The interest in topics such as the environment, health and sustainability has increased dramatically in recent years, due to concerns about global warming and demographic change, giving way to the concept of “green branding”.
This bachelor thesis proposes the application of a green branding strategy in order to position Irish agri-food products in the German grocery retail market, and explores its potential effectiveness and current relevance. Firstly, this work intends to offer an overall understanding of the characteristics and implications of a green branding strategy. Secondly, it analyses the connection with Ireland as a country of origin for agri-food products, by putting forward the different arguments for its suitability for the respective products. Finally, the key learnings regarding the successful implementation of a green branding strategy are discussed, based on a real-life best-practice case.
This research employed previous academic and trade literature to develop a theoretical foundation for understanding the concept of green branding in a marketing context. Various forms of industry, consumer and retail insights were used to identify the extent of demand for green brands in Germany and to analyse strength and weaknesses of the Irish agri-food industry in this regard.
An expert interview with the Marketing Manager for Kerrygold in Germany was conducted to uncover points arising from the best-practice application of a green branding strategy.
The findings indicate that there is significant theoretical and practical evidence to suggest that the application of a green branding would be an effective positioning strategy for Irish agri-food in the German consumer market.
Sales promotion are commonly used tool by marketers to manipulate consumer toward a certain offer or product. Attractiveness of a promotion can increase the demand of the promoted product. Monetary and non-monetary are considers the two main types of sales promotions. Monetary sales promotion, also known as price promotion, will provide immediate price discount upon purchase, for example 50% discount. Non-monetary sales promotions or premium promotion, on the other hand, usually grant consumer an extra free product or additional service for free. Previous studies also demonstrated that different sales promotion affect consumer behavior differently. Consumers’ value perception can be influenced by several factors. For instance, marketers use specific “phrase” such as “value pack” to influence consumer price perception. Rationally, consumers’ value perception should remain unchanged regardless of the phrases use to describe the promotion with same discount value. In this study, we examine the impact two sales promotion those are “50% discount” and “buy one get one free” on value perception of Thais consumers. These two deals have equal economic value but perceived differently by consumer. We aim to answer the question “does two different deals with the same value impact value perception of the same product differently?” In order to obtain logical answer, two set of questionnaires were send out to observe the maximum price which consumer willing to pay for “instant noodles” and “soy protein powder”. Unfortunately, the result from our survey were not significant enough for us to derive a concrete conclusion. We also discuss about potential cause of the unexpected result and interpret our result for better understanding. Even without a significant finding, this paper address that different sales promotions impact consumer in various ways supported by other literatures and also self-assumption.
Industry 4.0, a term coined at Hannover Messe in Germany in 2011, is believed to be the next disruptive force, driving human progress and innovation. The advent of technologies, such as the Internet of Things, Cloud Computing, Big Data, and new Mobile Technologies, fuel this disruption. To enable Industry 4.0, mankind is dependent on technological infrastructure, provided by companies, operating in the semiconductor industry. Over the last years, these companies have increased their profits and their stocks are currently trading near all-time highs. Yet, uncertainty created by the disruption of Industry 4.0, the growing influence of China on the semiconductor market, economic insecurities created by political uncertainties, like the 2020 US Presidential election, and the risk and implications of a second global wave of the COVID-19 pandemic, make the equity valuation of leading and established companies in the semiconductor industry exceptionally challenging. This paper examines, how different equity valuation methods compare under said circumstances and shows sophisticated valuation methods must be used to limit valuation error. Further, this paper gives an estimation of the possible ranges of value and suggests the industry may currently be overvalued.
The impact of store atmosphere elements on the purchase behaviour and emotions of customers has an important significance in modern marketing. How to design and conceptualize a store atmosphere in such a way that it provides an unforgettable experience for the customer and entices him or her to arouse an interest in the store environment is one of the most fundamental concerns merchants and marketers must ask and think through these days – likewise, the role of culture in connection with store atmosphere is necessary to understand. The goal of this paper is to answer the question on how behavioural and emotional responses to store atmospheric elements such as visual, aural, olfactory, tactile, social, exterior design, interior design and layout & design differ across individualist and collectivist cultures. A cross-cultural analysis between Germans and non-Germans is made in respect to the posed question. A quantitative online survey was conducted, in which a total of 99 valid participants took part, of which 57 were Germans and 42 were non-Germans. This research extended the study of Barros et al. (2019) and added two more separate store atmospheric elements which are the general exterior design and the general interior design. The data was then analyzed, and the findings were ultimately presented. The findings showed that overall store atmosphere elements have similar emotional and behavioural effects on individualist and collectivist cultures with the exception of the general exterior design element, where a significant difference was found. This paper gives a comprehensive overview on the importance of store atmospheric elements in retail and the comparison between Germany which acts as a country that scored relatively high on the Individualism dimension of Hofstede’s national culture model and the countries Turkey, Russia, Portugal, Albania, Bosnia, Romania, Kazakhstan, Vietnam, Sri Lanka and Iraq which serve as a union of cultures that performed high on the Collectivism dimension. Additional research on the topic needs to be done on how culture affects shopper’s emotional and behavioural responses.
Digitalization is one of the global megatrends of the 21st century. With the increase of mobile technology, constant connectivity, and data analytics, organizations are forced to become more digital to keep up with the increasingly digital world.
This research addresses the changing role of leadership due to digitalization. It examines factors which need to be considered when driving digital transformation in organizations as well as leadership competencies necessary in the digital age. Finally, the research addresses the resistance to digital transformation in organizations.
To investigate how leadership is affected by digitalization, qualitative research is carried out. The research is based on published secondary data.
The findings of this research suggest the growing importance of leadership in the digital age. Leadership needs to approach digitalization actively, thus driving digital transformation in organizations to stay competitive in the increasingly digital world. Further, the research suggests six leadership competencies which are essential in times of digital transformation and identifies two leadership roles which have arisen in recent years due to digitalization. Finally, the research proposes ways to overcome resistance to digital transformation.
A Descriptive Study on Customer Attitudes towards Green Branding in the Fashion Industry in Germany
(2021)
This paper attempts to provide an up-to-date representation and analysis of customers' attitudes towards green branding in the fashion industry and their willingness to pay (WTP) for sustainable and ethical clothing in Germany. Related literature strands are reviewed to understand how the fashion industry works, what green branding means, and how customer attitudes are shaped. After creating an attitude measurement model, an online questionnaire was designed and sent to Furtwangen University students, with 153 valid responses returned. The descriptive analysis sheds light on the three attitudinal components related to sustainability and ethics in the fashion industry. It is noted that customers do not hold a definite attitude. However, a tendency towards the positive end is ascertained. Significant gaps still exist in terms of knowledge and awareness of some commitment by fashion brands. Another huge factor influencing attitudes appears to be a lack of trust. The behavioral component showed that customers are trying to contribute through proper disposal and are willing to buy sustainable and ethical clothing more often. However, there is still some room for improvement in terms of customer education. Nevertheless, it is found that they are willing to accept an additional contribution for sustainable and ethical clothing. In general, it can be concluded that there is a foundation to improve the fashion industry towards more sustainability. However, all stakeholders, i.e., customers and fashion brands, as well as the government, need to work together to change the industry in the long run.
The real-world possibilities for blockchain applications are endless, yet few real-world use cases exist in early 2018 beyond cryptocurrency. Among the many newly initiated and emerging proposals for applications of this unique technology, the area of vehicle emissions provides an opportunity to bring the advantages of cryptography and decentralized databases to the collection and storage of scientific research data. The reporting of vehicle emissions has been a publicly acknowledged area of deceit and scandal, while the cornerstones of blockchain are transparency and consensus. There is, perhaps, a way for this newly expanding technology to provide a disruption to the automotive industry by efficiently and reliably reporting vehicle emissions.
This paper seeks to analyze: the capabilities of an emerging technology when applied to an existing older technology and its utilized environment as well as propose a system for efficiently and reliably collecting and reporting internal combustion engine based vehicle emissions data using blockchain; also, finally, theorize the impact of such a system on the automotive industry.
By combining multiple technologies which already exist in practice, as well as some which are expected to be massively implemented in the near future, it is theoretically possible to establish a blockchain based system for not only recording emissions from every participating vehicle, but also electronically executing a check against local emissions restrictions via smart contracts defined by geo-locational range and GPS referencing. The data can be processed and stored in a way that protects the identity and location history of the driver by assigning responsibility of compliance to the identity of the vehicle. The network can be protected from malicious actors by way of an emissions application specific protocol which involves unique GPS data.
While the short run effects of such a system may be met with pushback from the automotive industry because of increased regulation and impact on sales of internal combustion engine vehicle inventory, the long run effects parallel and may even supplement the future effects of the global trends which make the system possible.
When scaling, startups face managerial challenges and a downfall in innovation. A growing team and the resulting increased communication and organizational complexity bring issues previously not existing. Accountability Systems can assist startups overcome the mentioned issues and maintain their essence of innovation, vital for their success.
This paper discusses the relevance and benefits of implementing formal managerial systems in a growing startup. By mapping out the interdependence of culture, innovation and growth, it is demonstrated how Accountability Systems can support the preservation of an innovative culture when scaling a startup.
In a time when innovation is often disregarded due to a focus on process efficiency, Accountability Systems can provide a valuable tool for managing transition. This thesis serves as a general evaluation of Accountability Systems and their benefits. It is important to note that this paper is not intended to serve as a directly adaptable guide for startups.
Akka Cluster
(2021)
Akka Cluster ist ein Framework, das die Entwicklung verteilter Systeme ermöglicht. In dieser Arbeit wird der Funktionsumfang von Akka Cluster untersucht, ein Teilbereich des Frameworks Akka. Gegenstand der Analyse ist ein einfacher, mit Akka aufgesetzter Cluster, um anschließend Funktionen wie Singletons, Sharding, verteilte Daten und Mechanismen zur Fehlertoleranz zu untersuchen. Dabei wird auch versucht, unter die Abstraktionsschicht zu schauen, die Akka Cluster bietet. Dies gibt unter anderem ein klareres Bild, wie umfangreich die Entwicklung verteilter Systeme ist. Durch Monitoring soll anschließend ein Überblick über einen Cluster gegeben werden, welcher über eine REST-Schnittstelle auch anderweitig verwaltet werden kann.
This study is aimed at valuing two companies in the IT services industry with different valuation approaches. Therefore, the preconditions for an accurate and meaningful business value as well as the procedure, strengths and limitations of these approaches are examined. Additionally, the accuracy of the results is determined through comparison of valuation estimates with their corresponding stock prices occurring within the three months following the business valuations.
Furthermore, it is examined if one valuation approach is superior in terms of accuracy. Finally, to verify the quality and explanatory power of the valuation results, they are compared with the outcomes of the study on the information content of equity analyst reports by Paul Asquith, Michael B. Mikhail and Andrea S. Au. The results of the business valuations show that within the three-month period, no price target was exactly achieved by the corresponding stock prices.
Furthermore, no valuation approach could be determined that is significantly more accurate than the others. It can be concluded that despite some limitations in the explanatory power of the valuations, the average percentage approximations of Mastercard’s and Visa’s stock prices to target prices were only slightly below those of the comparative study. In view of the fact that the research capacities and experience behind these business valuations are significantly lower than those of the top analysts in the comparative study, the results are considered consistent with the outcomes of the study on the information content of equity analyst reports.
An analysis of the inter-rater reliability of ESG ratings within the consumer staples industry
(2020)
The aim of this study is to gain further insights into whether ESG ratings of the same firms from different rating agencies differ. To this end, this study examines and compares in particular the ratings of the providers Bloomberg, Sustainalytics and MSCI for companies in the consumer staples industry. The study comes to the conclusion that there are in some cases significant differences between these three providers in terms of the respective ESG ratings. Furthermore, a company-size bias is shown for Bloomberg and Sustainalytics ESG ratings. It appears that these agencies rate companies with a large market capitalization better than firms with a lower market value. These large discrepancies in ESG ratings of companies within the consumer staples industry and individual rating problems, such as the company-size bias, mean that today's ESG ratings tend to be not reliable and not valid. The study shows that ESG ratings will have to change a lot in the near future in order to contribute positively to the investment selection of socially responsible investors.
The aim of this study consists oftwo main objectives: First,to investigatethe penetration and preferences of fintech solutions from the payments sector within the studied population, as well as the elaboration of a forecast for the upcoming years.Second, to examinethe main elements that influence the intention of young customers when deciding to adopt fintech-basedpayment solutions. Existing research has tested several factorsfrom which the variables of trust, transaction efficiency and ease of use are included onthis paper. Additionally,the value-added propositionfrom this studyis represented by the incorporation of sustainability-related purposes into thisanalysiswith the intention of reflecting the increasing presence of efforts to integrate this component within thefinancial industryin recent years.A research model is proposed and tested by including elements based on theTechnology Adoption Model (TAM). By exploring the results of primary data through asurvey with 463 responses from university studentsandexamining secondary sourcesof information, the findings of this study demonstratethat all four tested variables have a positive impact on the intention of using fintech-based payment solutions.Sustainability-related purposes do not play a major role in the decision of using these apps, however, even with a minimal influence, theeffect on intention is positiveand statistically significant. The findings of this study pose important implications for stakeholders within the fintech spectrum whose purposes are related to increasing the intention of young consumers towards using these productsandto provide enoughevidence of the importance of designing incentives that fuel sustainability stewardshipwithin the financial sector.
Sustainability, encompassing the economy, the environment, and society in equal parts, is an increasingly prominent topic that is gaining in importance and awareness due to the climate crisis and the resulting urgent need for action. It is essential to simultaneously focus on the global and on the local scale in order to create a paradigm shift. This study addresses the attitude-behavior gap of employees in the daily operations within companies and evaluates how nudges can be implemented to narrow this gap. A literature review was conducted to understand the separate topics of sustainability, the attitude-behavior gap, and nudging. Based on these three topics and their interrelation, exemplary nudges on habits and on infrastructure to be applied in a company and modified to its needs are developed. The method of implementation of nudges cannot be generalized because (1) attitudes and behavior and their interrelation are individual and influenceable factors and (2) the corporate context and how nudges are communicated impact the effectiveness of the interventions. Investing in internal sustainability practices in combination with indispensable external practices leads companies to a holistic, authentic, and successful approach towards becoming a sustainable business.

An average investor trying to allocate his wealth among multiple assets ideally has nearly infinite possibilities to do so. However, asset allocation strategies try to facilitate this process. Nevertheless, no consensus exists on which strategy is ideal and yields the best performance. Therefore, this paper aims to determine an ideal asset allocation strategy for an average investor by comparing two asset allocation strategies.
The focus is on comparing the practical application of Markowitz’s Modern Portfolio Theory (MPT), a sophisticated asset allocation strategy, with an equally weighted asset allocation, namely the 1/N strategy. The past performance of these two strategies is compared with the help of a calculation example based on historical data. The quantitative analysis covers three time periods of different lengths between 1991 and 2022. Also, the strategies are applied to portfolios with different amounts of assets during these periods. Although the existing literature is very controversial concerning the performance of the two strategies, this research shows a clear result. Compared to the 1/N strategy, this study’s findings show an outperformance of the MPT strategy during every period and each portfolio combination. However, the difference in performance regarding return and risk is minimal in most scenarios and would not significantly affect an average investor who invests over a long-term horizon.
This thesis talks about the relation between investor sentiment, stock return and trading volume in the German stock market. Six Granger causality tests were performed in order to determine, whether one of the above mentioned factors is indicative of the others. The results imply that investor sentiment is indicative of both, stock return and trading volume in the specified time period. However, there is no further significant evidence for other relations among the variables. The results are mostly in line with the literature available on this topic and back up the importance of the concept of investor sentiment as investor sentiment delivers an attempt to explain why investors behave irrationally on the stock market. Hence, the factors influencing investor sentiment should be subject to further research in order to gain a broader understanding of the topic.
The present research sought to deepen the debates about how the collector of recyclable material, a subject that has built his political resistance in the Brazilian scenario from the process of re-signification of garbage and his profession. Its empowerment observed from the end of the 20th century was concomitant with the growth of environmental discussions and the strengthening of the solidarity economy as an alternative for economic emancipation in Brazil. In this context, the individual who used to live on the margins of society established himself as a fundamental factor in the recycling chain and became an environmental agent. The question that guided the investigation was "how has the pandemic influenced waste pickers' solidarity organizations, given their challenges and opportunities?". In this context, two specific objectives were determined to be answered in the course of the research. The first sought to understand the relationship between the solidarity economy and the formation of waste picker collectives; the second aimed to identify the challenges and opportunities that could arise from these solidarity organizations' experiences. A vast theoretical analysis was conducted to understand the
foundations of the Solidarity Economy, an alternative to the informal economy and a form of economic empowerment especially considered for vulnerable populations, as a
way to include them economically. Using the case study of Belo Horizonte, a city with a history of alternative economic expressions and strengthened waste pickers' movements, we approached various actors of the recycling chain through qualitative research, using
the in-depth interviews approach.
Among other findings, the research noted that one of the greatest challenges of the post-pandemic Solidarity Economy is related to the expansion of the capitalist market to areas traditionally aggregated by the Solidarity Economy, because they were previously considered to be on the “margins of society”. However, these threats also
give room for opportunities, from responses that reinforce the legitimacy of cooperatives and associations, through their contractual adequacy with the City Hall for
the payment of the environmental service rendered, disconnected from the number of solid waste collected. We have learned that in the daily struggles and achievements of
the waste pickers, challenges and opportunities go hand in hand.
Jährlich sterben etwa 3.000 Menschen bei Verkehrsunfällen in Deutschland. Trotz technischen Fortschrittes der Fahrzeuge und steigender Sicherheit im Straßenverkehr nimmt die Anzahl an Verkehrstoten nur minimal ab. Im Vergleich zu 1950 hat die Zahl an zugelassenen PKW in Deutschland deutlich zugenommen. Um die Anzahl der Todesfälle zu verringern, wurde durch die Europäische Union das 112-eCall Notrufsystem für alle PKW und leichten Nutzfahrzeugen mit einer vollen Typenzulassung ab dem 31.03.2018 verpflichtend eingeführt. Öffentliche Notrufleitstellen sowie der ADAC klagen über häufige Probleme mit dem eCall System. Fahrzeughersteller und andere Firmen dürfen auch ein eigenes eCall Angebot anbieten, wenn gewisse Bedingungen erfüllt sind. Bei Verkehrsunfällen ist eine schnelle Rettung und Transport in ein geeignetes Traumazentrum maßgeblich dafür verantwortlich, welche Überlebenschancen die verletzte Person hat. Ziel dieser Arbeit ist es, die verschiedenen eCall Arten anhand von Leitstellendaten zu untersuchen und zu ermitteln, wie viele dieser Einsätze in den Leitstellen eingegangen sind. Es sollen außerdem die Qualität und die Unterschiede der beiden Systeme in einer örtlichen Analyse ermittelt werden.
Das Streben des Menschen nach persönlichem Wohlbefinden steigt mit dem Wohlstand – die aktuelle Pandemiezeit wirkt hier stark beschleunigend. Den Traum von einem eigenen Wellnessbereich im privaten Heim erfüllen sich immer mehr Privatpersonen.
In der vorliegenden Arbeit wurde der Geschäftsprozess der Saunafertigung untersucht. Dabei lag der Fokus der Analyse auf den einzelnen Prozessschritten des Fertigungsprozesses hinsichtlich Zeit, Material, Maschine und Mensch. Die herausgearbeiteten Optimierungsansätze orientieren sich dabei an dem magischen Dreieck und der Digitalisierung.
Es zeigte sich, dass viele Prozessschritte noch händisch und in Papierform durchgeführt werden. Der technisch bereits mögliche Einsatz von digitalbasierten Schritten ist nicht in vollem Umfang ausgeschöpft. Für eine effiziente zukunftsorientierte Prozessgestaltung ist die weitere Digitalisierung unerlässlich.
This paper analyses five different Cryptocurrencies, namely Bitcoin, Ethereum, XRP, Dogecoin and Litecoin, and studies their impact on traditional financial portfolios under different allocation strategies. The allocation strategies under consideration in this paper are the modern portfolio theory according to Markowitz, an extension of it such as the tangency portfolio, and the equally weighted portfolio. Further, this study explores the effect on the efficient frontier when Cryptocurrencies are added to the efficient portfolios. In addition to that, the paper aims to examine whether the mean – variance portfolio optimization according to Markowitz outperforms the naïve and tangency portfolio strategy. The portfolio performance is evaluated based on the Sharpe ratio. The quantitative analysis of this paper covers the time period from 2017 to 2022, in total five years. In accordance with the existing literature on portfolio optimization with Cryptocurrencies, the study reveals that besides some issues related with Cryptocurrencies such as cybercrime and a lack of regulations, Cryptocurrencies can be beneficial for portfolio diversification with traditional financial assets. Referring to the portfolio strategies, the study highlights that the optimal mean – variance portfolio and tangency portfolio do not differ significantly in terms of Sharpe ratio. However, both strategies outperform equally weighted portfolios.
The following study examines the influence selected variables have on the price of the cryptocurrency Bitcoin by utilizing a multiple linear regression model. Data of 267 observations for each variable during a five-year period from 13 August 2016 to 1 October 2021 are analyzed. The results present empirical evidence on the relationship of Bitcoin and external determinants such as traditional financial assets, in particular the stock market, the bond market, domestic currencies, the real estate market, gold, and the popularity of Bitcoin, represented by a Google Trends analysis. The findings imply that only the stock market and the real estate market proxies significantly influence the price of the cryptocurrency Bitcoin.
New developments in decentralized ledger technologies may have a huge impact on how we perceive and use money now and in the future. Most notably, it has led to the development of cryptocurrencies and a variation thereof –stablecoins. This thesis discusses the potential impact of Proof of Work based cryptocurrencies such as Bitcoin on the money market and the central bank’s ability to maintain control over the money supply. The IS-LM model is used to evaluate the effects of a private-issued digital currency. However, due to the characteristics of POW based cryptocurrencies, their impact on the money market is neglectable. In contrast, private-issued stablecoins of large international businesses with the potential of gaining enough users to overcome hindering network effects may pose a serious threat to the financial system, if there is no regulation on their usage.
As a response to this development and combined with the phenomenon of a declining cash usage in many countries, central banks have started to conduct research in their own digital currency, namely central bank digital currency (CBDC). Countries such as Sweden or The Bahamas have already started with the implementation of trial phases of their respective CBDC. However, design choices of the country’s digital currency differ due to financial, geographical, and cultural circumstances, among others. Nevertheless, many countries have utilized decentralized ledger technologies as the underlying technology for CBDC, showing its promising potential for further research and future developments.
The relation between Frugal Innovation and Sustainability is a widely discussed topic in current academic literature. To assess the correlation between these two concepts, a sample of the most frequently mentioned Frugal Innovations was selected. The criteria to evaluate the sustainability potential for each of these cases was built upon the UN Sustainable Development Goals, a global reference indicator. Frugal Innovations among the banking, transport, energy, ICT, water, appliances and healthcare sectors were evaluated. The results suggested a positive contribution and impact of Frugal Innovations towards economic, social and environmental development.
This paper deals with the constructive adaptation of an existing mechanical single-jet valve meter (valve meter driven only by a water jet) for the realisation of a digital system. For this purpose, an existing mechanical single-jet valve meter system is constructively adapted in such a way that the existing mechanical counter can be replaced by an existing digital counter. Subsequently, the measuring behaviour of the newly created meter system is examined on a testing bench

Prostate segmentation is an essential part of brachytherapy treatment planning, in order to perform the procedure with required accuracy. Nowadays, segmentation of the prostate is still carried out manually during the planning steps, therefore it is a process that can be tedious, time-consuming and prone to inter-observer error. Much effort has been made in development of an computer-based algorithm that can perform prostate segmentation automatically, but only with appearance of deep learning methods, more promising algorithms emerged. So far, convolutional neural networks demonstrated excellent results in fully automatic prostate segmentation. Development of such an algorithm and training an efficient deep learning model is a challenging task, and requires a lot of optimizations. The objective of this study is development and evaluation of an algorithm for image processing based on deep learning methods that can perform fully automatic segmentation of the prostate gland in transrectal ultrasound images. Additionally, we made an overview of the development process, along with challenges and their solutions and demonstrated an algorithm implemented using Python and Tensorflow library, consisted of preprocessing, augmentation, training and validation, postprocessing and validation steps, which is able to successfully carry out fully automatic prostate segmentation with expert level of accuracy. Finally, we presented our implementation of fully convolutional neural network model and results that are encouraging to continue with model improvements and potential clinical application.
Das Ziel des vorliegenden Forschungsprojektes war es, eine kostengünstige, aber effektive und flexible Automatisierungsmaßnahme für Fräsbauteile einzurichten. Dadurch sollte der Mitarbeiter entlastet und für anderweitige Tätigkeiten eingesetzt werden, um durch diesen Aspekt zeitgleich Kosten einzusparen. Zudem musste die Lösung für zukünftige Optimierungen und Veränderungen an der Maschine ausgelegt sein. Durchgeführt wurde das Forschungsprojekt an einer 3-Achs CNC-Fräsmaschine (Chiron Mill 2000). Die Automatisierung bezieht sich auf die Entnahme von unterschiedlich langen Werkstücken (76 bis 400 mm), deren Abtransport aus dem Maschinenumfeld sowie das Nachschieben des Rohmaterials. Um eine zielgerechte Lösung zu finden, wurden Methoden wie der morphologische Kasten herangezogen. Es entstand eine einfach handhabbare und kosteneffiziente Lösung mit einem Transportband, einem pneumatisch beaufschlagten Spindelgreifer und einem profilgenauen, konstruiertem auf den Greifer montierbaren Fingerpaar. Mit dem Forschungsprojekt wurde eine deutliche Steigerung der Eingriffszeit durch einen Mitarbeiter ermöglicht, wobei aber die Prozesszeit für einen Zyklus angestiegen ist. Zudem konnten die Kosten für die Produktion der Bauteile deutlich gesenkt werden. Durch die Automatisierungslösung konnte der Werker von monotonen Arbeitsgängen befreit und für stärker wertschöpfende Tätigkeiten gewonnen werden.
In dieser Bachelorarbeit wird die Bedrohungslage durch den Einsatz von frei erhältlichen Drohnen zur Beeinträchtigung der Informationssicherheit von Organisationen umfassend untersucht. Unter Verwendung einer Kombination aus Literaturanalyse, Experteninterviews und Fallstudie wird die Vielfalt der Bedrohungen und die Machbarkeit von Drohnenunterstützte Angriffen auf die Informationssicherheit detailliert beleuchtet. Dabei zeigt sich, dass Drohnen eine reale und vielschichtige Gefahr darstellen. Die Einschätzung der Eintrittswahrscheinlichkeit solcher Angriffe ist aufgrund der dynamischen Entwicklung der Drohnentechnologie und der Vielfalt der Anwendungsmöglichkeiten komplex. Diese Arbeit betont die Notwendigkeit für Organisationen, effektive Abwehrstrategien zu entwickeln, und weist auf die Wichtigkeit weiterer Forschung in diesem Bereich hin, um den Herausforderungen der technologischen Entwicklungen und der sich ständig ändernden Bedrohungslandschaft gerecht zu werden.
After the Second World War and especially in the early 70s a new phenomenon arose – today widely known as globalization. It eliminated barriers and thus increased international competition. Companies such as Siemens, General Electrics and Procter & Gamble were forced to act globally in order to stay competitive and therefore they had to redefine their businesses in a strategic and internationally oriented manner. As one of a company’s most essential departments, human resources was tremendously forced to adapt to the changed business environment. Language skills, cultural awareness and global mobility were only a few new requirements in human resources.
Early in the beginning of globalization, large companies recognized the opportunity to outsource specific departments with the goal of cost-saving and resource bundling. Manufacturing was and still is a predestined department to make use of outsourcing, whereas the situation for other departments including IT, procurement and human resources is more complex. The main fear is losing control to the outsourcing partner. Main departments with a strategic importance for the overall success are therefore only conditionally suitable for outsourcing. Companies need to ask themselves, how much control over their human capital they are willing to sacrifice for saving costs and staying competitive. With the purpose to evade this conflict of objectives, companies seek for a hybrid model, which allowed them maintaining control and cutting costs at the same time.
In the early 70s, first companies found the solution in the Shared Service Center model, which then rapidly spread throughout a number of countries and industries. Human Resources Shared Service Centers can be defined as a hybrid model, combining advantages and avoiding disadvantages of outsourcing and decentralization of Human Resources. The Shared Service Center model is expected to lower costs, improve efficiency and service quality, and enable organizations to better focus on core functions. Although the strategy seems only having advantages, there are many aspects to consider in the pre-implementation phase. Moving to the Shared Service Center model represents an immense strategic project, including high risk, costs and impact on the overall success. For this reason, the project needs to be well planned, designed, implemented, monitored
and evaluated from the right people, at the right time and at the right place. Any small mistakes made during the project might have an unpredictable and irreversible impact and prevent the company from benefiting of the Shared Service Center model or might even force the organization to stop the project completely. Before deciding to implement Shared Service Centers, companies need to accept that there is neither guarantee for success nor a universally valid success strategy. Best and worst practices will be discovered during the transition at the earliest and a success evaluation can only happen in the post-transition phase. Although the Shared Service Center model is not a recent trend as it found first-time application many decades ago, the topic remains relevant as many companies still hesitate implementing this risky strategy. Some organizations succeeded, others failed and returned to their old approach while some are currently in the transition phase.
Before deciding to move to the Shared Service Center model, one of the top pharma company’s was facing the same issues as other companies on such a scale. The management increasingly felt the pressure to offer the same or an even better service quality at a lower price. Changing the strategy and implementing Shared Service Centers across the globe was seen as the most promising solution. The large pharma company with employees of many nationalities worldwide offers a huge variety of cultures, which can be seen as a chance, but also as an obstacle on the way to a successful Shared Service Center implementation. Primarily, the company has to consider that the project might not work in the same pace, quality and method for all countries. Finding best practices for all countries is a desirable goal, yet not easy to achieve.
With information on corporate ethical behavior now more accessible than ever, consumers have become increasingly socially and environmentally aware, which has translated into a growing demand for ethically made products. For ethically minded consumers, certification labels such as fair trade or organic are simple indicators of whether a product meets their ethical standards. For companies that wish to become certified, which is a lengthy and sometimes expensive process, there are several pertinent questions to consider, such as how much customers really value particular labels and whether multiple labels yield significant added competitive benefits. One should also consider how best to collect this information, because simply asking customers via surveys isn’t guaranteed to return results that actually reflect or predict real-life behavior (Carrington et al. 2010). For this paper, we collected information on consumers’ willingness to pay for products with the organic and fair trade labels (both individually and in combination) using two different methods: a traditional questionnaire and a reaction-time based electronic research method designed to reveal subconscious value perceptions. The factors involved were product type and number of labels. We found little evidence to suggest that additional ethical labels significantly increase willingness to pay.
Biomedizinische Statistik
(2024)
Die klassische konfirmatorische Statistik, auch frequentistische Statistik genannt, setzt voraus, dass man theoretisch unendlich viele Stichproben ziehen kann, und dass dann die aus den Stichproben berechnete Prüf- oder Testgröße unter der Nullhypothese H0 eine bestimmte Verteilung annimmt. Meistens sind die Testgrößen so konstruiert, dass bei Ziehung der Stichproben aus immer derselben Grundgesamtheit (es gilt die Nullhypothese H0) eine Verteilung der Testgröße um den Wert null herum entsteht, z.B. in Form einer Glockenkurve, d.h., kleine Werte überwiegen. Große Werte der Prüf- oder Testgröße kommen mit geringer Wahrscheinlichkeit vor und signalisieren einen möglichen Ausnahmefall. Statt anzunehmen, dass einer der seltenen Fälle einer großen Prüfgröße eingetroffen ist, nimmt man lieber an, dass sich die Grundgesamtheiten unterscheiden (Alternativhypothese HA).
The purpose of this paper has been to find out if the reengineering project at Daimler Trucks has been successful. In order to eloquently do so, the field of Business Process Reengineering (BPR) has been researched with regard to performance measurement. The theoretical part of the thesis concluded with choosing one methodology out of the findings.
The second part is about the consequences of Daimler AG top management’s decision, reacting to changes in business environment, to restructure the Finance organization of all its divisions. Daimler Trucks used that change which included office relocation of the accountants to where their controlling colleagues have been seated and the newly gained local proximity to execute the project Integration Accounting & Controlling (IAC). The goal has been to reengineer the closing process by eliminating redundancies and defining clear responsibilities.
The third part of the thesis is presenting the result of measuring process performance before and after reengineering according to the derived research methodology of part 1. Quantitative as well as qualitative evaluation shows an increase in efficiency and effectiveness. A conducted online survey, asking all involved employees, aligns with this result and names key success factors such as communication and transparency. Despite the undeniable success of IAC, maintaining a continuous improvement process is recommended.
The goal of this thesis is to give an overview of the carbon footprint of the commercial aviation industry and to introduce measures to mitigate emissions. This will be done by taking the German Lufthansa Group as an example.
In the first part, relevant theoretical background information will be given. It will be shown that the commercial aviation industry is subject to steady and relatively strong growth. Even though the global share of GHG emissions caused by air traffic is currently relatively low, it is projected to increase in accordance with overall industry growth.
In the second part, measures taken by the aviation industry to reduce its emissions are presented using the example of Lufthansa. The measures that are taken are various, reaching from fleet renewal over infrastructural improvements such as airspace management to alternative fuels. It is also shown that the efficiency of an airline depends on different things and hence leads to different performances in the industry.
Even though the reduction of emissions is typically related with a reduction of costs for the aviation industry, the progress in some areas is still relatively slow.
Beginning in the mid 2007’s the US financial market started to slide into the “worst financial crisis since the Great Depression of the early 1930’s” (Thakor, 2015: p.156). The domino effect of several events and occasions were leading first to a countrywide recession in the USA then later spreading globally. In the following this term paper will deal with the main causes and effects of 2008 financial crisis. Unlike other topics in literature there is no consensus about the question of guilt in this sense. Among economists there are different approaches to explain the main causes of the financial crisis.
It is a fundamental right of every natural person to control which personal information is collected, stored and processed by whom, for what purposes and how long. In fact, many (cloud based) services can only be used if the user allows them broad data collection and analysis. Often, users can only decide to either give their data or not to participate in communities. The refusal to provide personal data results in significant drawbacks for social interaction. That is why we believe that there is a need for tools to control one's own data in an easy and effective way as protection against economic interest of global companies and their cloud computing systems (as data collector from apps, mobiles and services). Especially, as nowadays everybody is permanently online using different services and devices, users are often lacking the means to effectively control the access to their private data. Therefore, we present an approach to manage and distribute privacy settings: PRIVACY-AVARE is intended to enable users to centrally determine their data protection preferences and to apply them on different devices. Thus, users gain control over their data when using cloud based services. In this paper, we present the main idea of PRIVACY-AVARE.
Islamic banking is the new trend emergent within the modern-day banking industry, yet minimal literature is written about it. Most of the literary content today is regarding conventional banking, especially in non-Muslim countries and continents, Europe and U.S. included. Lack of literature is a threat to the operationalization of both modes of banking, due to lack of information and market analysis data. One of the fields where minimal literature coverage exists is market regulation – which is basically information as to how these two types of banking are regulated according to legislative structures. In light of this literature gap, this study emerges to explore the market regulative structure of both Islamic and conventional banks. The methodology to collect primary data is through interviews of selected players in both Islamic and conventional banks, such as bank managers, consultants, and personnel in the IT and finance department. The results of the interviews demonstrate that Islamic banks are faced with shortage of market regulation structures while conventional banks, on the other hand, are overwhelmed with over-regulation. The study provides several feasible solutions for these challenges.
Die vorliegende Bachelorarbeit gibt einen Überblick darüber, inwiefern die gängigen Nachhaltigkeitslabels in Deutschland eine Hilfe für den nachhaltigen Konsumenten sind.
Dazu wurden 8 handelsübliche Labels miteinander verglichen. Das Hauptproblem der Labels war die fehlende Glaubwürdigkeit, aufgrund von fehlender Transparenz. In einem zweiten Schritt wurde ermittelt ob, und wenn ja, um wieviel sich die persönliche Zahlungsbereitschaft auch tatsächlich erhöht. Festgestellt wurde, durch Auswertung diverse Studien, dass sich die persönliche Zahlungsbereitschaft durchaus steigern lässt. Dazu muss die Preisbildung allerdings transparent nachvollziehbar sein. Es lässt sich sagen, dass sich die Zahlungsbereitschaft um ein Fünftel steigern lässt. Durch die Auswertung diverser Studien wurden Barrieren ermittelt, welche einen nachhaltigen Konsum erschweren. Auf Grundlage dieser Barrieren, wurden Handlungsempfehlungen entwickelt, durch die diese Barrieren überwindet werden könnten. Besonders interessant ist diese Arbeit für diejenigen, die den nachhaltigen Konsum fördern möchten. Dazu gehören die Initiatoren der bisherigen Labels, sowohl als auch zukünftige Initiatoren.

Cultural considerations for Germans working with Japanese in virtual teams for project management
(2019)
In today’s globalized and multinational working world, being part of a team that uses technology in order to cross distance, time zones and even organizations, a so-called virtual team is becoming increasingly common. While extensive research on this topic is available, most of the current research is very theoretical and only in part useful for a member of a virtual team in order to enhance performance. A clear guideline on how to effectively work in an intercultural virtual team is not existent at this point.
This research, aims to produce a clear guideline for Germans working in virtual teams with Japanese in the style of the Project Management Body of Knowledge Guide. Identifying the key challenges of virtual teams and the specific cultural differences of Germans and Japanese, based on Hofstede’s cultural dimensions model are the starting point for this research. Due to the specificity and the novelty of this research a grounded theory approach has been taken and in-depth qualitative interviews were conducted with 12 Japanese employees, who regularly work in virtual teams with Germans. Grounded in the experiences and challenges of the participants, the findings help construct a guideline for Germans working with Japanese in virtual teams.
Results are structured according to 4 of the key challenges virtual teams face: trust, communication, leadership and technology/knowledge sharing. The guideline addresses the different communication styles of Japanese and Germans, differences in hierarchical thinking as well as the more collectivistic point of view of many Japanese. The guideline, that has been produced, is intended as a quick guide including recommendations for Germans to enhance their virtual team work with Japanese.
Private equity investors acquire companies, aim to increase the company’s corporate value and thus aim at selling the respective company at a profit after some time. To increase the value of their portfolio companies, private equity investors employ three main value creation strategies. Financial leverage, multiple expansion, and operational value creation. There has been a significant shift in importance between these three value drivers. While in the 1980s more than 50% of value creation was achieved by leveraging equity with the help of debt capital, this value driver only accounted for 15% in the 2010s. Instead, the value driver operational value creation has gained significantly in importance. It alone accounted for 55% of total value creation in the 2010s, more than financial leverage and multiple expansion combined. The aim of this thesis is to answer the question which operational value creation levers private equity investors use to increase the value of their portfolio companies during the holding phase. In addition, the thesis deals with the question of operational value creation drivers of the future. These are derived based on prevailing megatrends of the future. Research on the operational value drivers used by private equity investors revealed that these drivers can be assigned to three main aspects.
These aspects are, on the one hand, financial aspects, where private equity investors take measures to improve working capital. Moreover, within the framework of financial aspects private equity investors influence the cost structure as well as the cost of capital and the capital structure. Furthermore, private equity investors assert influence on the governance structures of their portfolio companies. For the aspect of governance, measures such as replacement of management/change of management structure, monitoring and controlling as well as incentive systems were identified to increase the value of the company. Another identified aspect for value creation are strategic aspects. In terms of strategic aspects, private equity investors use the levers of mergers and acquisitions, organic expansion, outsourcing/insourcing as well as product and pricing strategies.
The research on the value creation levers that private equity investors will have to apply in the future in order to ensure value creation of their portfolio companies is based on the megatrends of digitalization, demographic change and sustainability. The research revealed the implementation of digitalization measures, employee, and talent management as well as the implementation of ESG criteria.
This thesis has structurally outlined value drivers that contribute to value creation in private equity investments. The research also showed that value creation levers taken can directly and indirectly influence the value of the portfolio company. Value drivers II with a direct effect on the change in equity value affect either revenue, margin or net debt, while the indirect value drivers affect the valuation multiple.
In a worldwide accessible marketplace with numerous competitors who try to beat prices and quality of services and products, it is vital for online businesses to strive for strategies to be able to survive in a competitive environment and to sustain growth. The company Usbstick-Producer has gained numerous customers in the German market, but nevertheless competes against many businesses which offer similar products to similar prices. Therefore, it is highly important to defend gained market share. Appropriate strategies and investments are necessary to implement in order to attract and retain customers.
The bachelor thesis aims to explore the nature of customer retention and to give the company Usbstick-Producer recommendations regarding possible improvements and customer retention strategies for the German market. The company’s goal is to retain more customers and to ensure customer satisfaction in order to guarantee profitability for the business.
In order to attain the objective of the thesis, a multi-method approach is being used. A literature review is carried out in order to develop a comprehensive analysis and theoretical framework on the topic of customer retention and related concepts. An internal and external analysis are conducted which help to understand the key drivers and most important influencing factors for the business using the PEST analysis, Porter’s five forces analysis and SWOT analysis.
Qualitative research is utilised in order to investigate the practical aspects of the topic in direct relation to the company. Valuable insights and expert opinions as well as experiences are collected during expert interviews in order to develop appropriate strategic recommendations.
The research concludes with strategic recommendations for the company Usbstick-Producer using the collected and analysed data of the literature review and expert interviews. In the conclusion, possible further research topics are assessed and limitations of the research are discussed.
Funding is the key to success for a start-up. Since start-ups are often operating in innovative industries, they rarely receive loans from traditional debt lenders such as banks. However, start-ups do have the option of acquiring money for company growth through equity financing. One possibility for this is venture capital. In this scope, Germany is significantly behind the United States of America due to various aspects. This problem shows the relevance of the topic and justifies the critical examination of this subject. This work aims to analyze the German venture capital market, its development over the last 20 years, its advantages on the one hand and its disadvantages on the other hand as well as its future perspectives. Beyond that, the differences between the German and the American venture capital market and its success factors are presented. To answer all research questions, a broad literature review in combi-nation with several conducted expert interviews, which are evaluated on the principle of the qualitative content analysis according to Mayring, is applied. The results of the analysis indicate that there are mainly three fields that are crucial for a successful venture capital market: Political actions, attitudes of the society, and the economic situation. Within these fields, some aspects of Germany are considered worse than in the U.S. In the United States of America politics often intervenes to create better conditions for investments via venture capital. Besides, the risk affinity of society in the U.S. is a major advantage compared to the risk-averse society in Germany. This is complemented by a pronounced start-up mentality in the U.S. and the positive attitude of society towards the failure of a new start-up. In Germany, the opposite can be found in both aspects. Nevertheless, the German venture capital market has developed positively in recent years and has some advantages, such as a wide range of government grants for start-ups and the opportunity for investors to earn high returns on the initial investment. All experts that were interviewed are very confident that venture capital in Germany will continue to develop positively. They identified the reasons for this evolution in an increasing number of start-ups and better skills among the founders, which increases a start-ups' chances of success. For this reason, the experts forecast rising yield expectations, as well as an increasing number of venture capital providers, and venture capital takers. This research also indicates that the volumes of venture capital funds will rise, and the COVID-19-pandemic will accelerate the development of venture capital in Germany. The results of the research clearly show that despite some weaknesses, the German venture capital market has been on a good path for several years, and that there is a high probability that the growth will continue in the future.
Diese Interventionsstudie untersucht die Auswirkungen eines Outdoor-Wildwassertrainings auf die Fähigkeiten des strategischen Planen und Denkens von Studenten an der Hochschule Furtwangen.

Um einen Lernerfolg beurteilen zu können, wurden sowohl teilnehmende Studenten an dem Training sowie eine Kontrollgruppe, nicht-teilnehmenden Studenten, mittels eines standardisierten Fragebogens zu einem Zeitpunkt vor und nach dem Training befragt. Die Auswertungen der Daten zeigten größere subjektiv eingeschätzte Lernerfolge seitens der teilnehmenden Studenten im Vergleich zur Kontrollgruppe.
A major problem in the automotive sector is dealing with used hydraulic oil. Since this oil loses its purity over time, it must be changed. In most cases, the condition of the oil is not really checked, but is changed after a certain number of kilometers. It is possible that intact hydraulic oil is wasted in the process. Until now, there is no cost-effective method to check the purity on hydraulic oils, so there is nothing left but to remove all of the oil. The purpose of this work is to develop a measuring station for a MEMS-based oil quality sensor. With the help of the oil quality sensor, deviations of aged hydraulic oils shall be investigated. An infrared light source and a Fabri-Perot spectrum sensor will be used for more accurate detection of deviations in aged hydraulic oil. The goal is to clarify whether it is possible to use wavelength spectra to detect differences in aged hydraulic oil. To do this, a suitable Fabri-Perot spectrum sensor and a light source with the appropriate wavelength range were carefully selected. Furthermore, a measurement setup for static measurements was worked out. Subsequently, measurements were carried out with and without hydraulic oil and the measured data was compared with reference data. Finally, differences in the aged hydraulic oil could be determined by means of light wave measurements.
Injury to the anterior and posterior cruciate ligaments is not an uncommon occurrence. A rapid movement can already cause such an injury. Reconstruction of the anterior and posterior cruciate ligaments (ACL/PCL) in the knee joint is a complex orthopedic challenge. In this context, the development of a graft preparation system is gaining importance. Such a system will help surgeons prepare grafts accurately and efficiently to optimize reconstruction processes. This can increase the accuracy of graft placement, reduce surgical times, and decrease recovery time and postoperative risk for patients.
This paper focuses on the development of a graft preparation system for ACL/PCL reconstruction in collaboration with Getsch+Hiller Medizintechnik. The challenges and requirements in developing such a system were analyzed to ensure functionality and effectiveness. Existing approaches and technologies were examined to identify potential improvements and innovations. Development included extensive research on ACL/PCL reconstruction using grafts, including various surgical techniques. A detailed analysis of the graft preparation process was performed to identify critical issues. The design of the graft preparation system is based on research data and is performed using CAD. The needs of the target group, customer requirements and findings from research were considered.
Die Frage ob das Elektroauto mittelfristig den Verbrenner in Deutschland ablösen wird beschäftigt momentan Politik und Medien. Aktuell stellen Elektroautos trotz staatlicher Förderung noch ein Nischenprodukt am deutschen Pkw-Markt dar. Die vorliegende Arbeit untersucht innerhalb einer ausführlichen Marktanalyse von Sekundärdaten ob und gegebenenfalls wann Elektroautos in Deutschland den Massenmarkt ansprechen werden. Hierzu wird der deutsche Pkw-Markt mithilfe von Modellen der Diffusionsforschung untersucht. Ziel der Diffusionsforschung ist es, die Verbreitung einer Innovation am Markt im Zeitverlauf zu beschreiben und zu erklären. Es wird dabei herausgearbeitet: welche Käufer Elektroautos momentan ansprechen, welche Faktoren erfüllt sein müssen, dass sich Elektroautos am Massenmarkt in Deutschland durchsetzen können und welche Faktoren den Verlauf der Verbreitung von Elektroautos in Deutsch¬land in Zukunft beeinflussen werden. Aus Basis der gewonnen Erkenntnisse wird schließlich eine Prognose zur zukünftigen Verbreitung von Elektroautos in Deutschland erstellt.

Ziel dieser Arbeit ist es zu erforschen inwiefern Führungskräfte den gesundheitlichen Zustand ihrer Mitarbeiter beeinflussen können. Macht falsche Führung krank? Wie kann man gesunde Führung umsetzen und warum ist das wichtig? Hierbei wird negativer Stress am Arbeitsplatz als Hauptfaktor für Burnout und psychische Erkrankungen näher analysiert. Traditionelles Führungsverhalten wird kritisch betrachtet und begründet folglich wichtige Ansätze gesundheitsförderlichen Führens. Die Bedeutung gesunder Führung und der Einfluss des direkten Vorgesetzten auf die eigene Zufriedenheit werden anhand aktueller Studien gezeigt. Gesundheitsmaßnahmen der leitenden Organisation und Personalentwicklung bilden zusätzlich wichtige Komponenten.
Jene Erwartungen, die heutzutage an die Führungspositionen gestellt sind, werden im weiteren Verlauf der Thesis hinterfragt. Welche Herausforderungen entstehen für Führungskräfte und Geschäftsleitung? Die Bedeutung von Führungskompetenzen und Führungskräfteentwicklung nimmt seit Jahren zu.
Als praktisches Beispiel dafür wurden zu den Forschungsfragen Interviews mit der jeweiligen Leitung des betrieblichen Gesundheitsmanagements zweier Unternehmen aus der Region Südschwarzwald geführt. Die qualitative Befragung ergab einen eindeutigen Bedarf an psychischem Gesundheitsmanagement. Die Rolle von Führungskräften wird in beiden Fällen als höchst bedeutend angesehen und in der Studienanalyse näher erläutert.
Differences in the perception and their effects on the implementation of organizational agility
(2021)
This thesis paper investigates the differences in organizational agility implementation and links practical approaches to complex theory. Several agile transformations have been studied to provide an overview of the common guidelines that foster agile working. In alignment with the ambivalence of agility, the results show that a symbiotic mixture of bottom- up and top-down features in the application is required. Especially in traditional organizations, where hierarchical structures prevail, the practical implementation requires the approval of managers and the active involvement of employees to be successful. Additionally, companies cannot apply a uniform approach to achieving agile but must alter practices to fit their specific needs. Consequently, this paper can be particularly beneficial to companies attempting an agile change.
Digital twin as a service : Ressourcenmanagement mit Energiedaten aus cyber-physischen Systemen
(2019)
Die Energiewende führt zu einer Paradigmenänderung. Der Zeitpunkt der Energieabnahme wird sich zunehmend an dem der Energieerzeugung orientierten. Die Steuerung des Energiebedarfs kann durch energieorientierte Produktionsplanung gesteigert werden. Dies erfordert eine Vorhersage des Energiebedarfs. Hierfür wird ein System entwickelt, das eine Modellierung mittels maschinellen Lernens nutzt. Die Datenbasis wird durch eine Vorgehensweise zur Abstrahierung von Fertigungsmaschinen erzeugt. Das System besteht aus gruppierten Microservices, es berücksichtigt die unterschiedlichen Anforderungen der Modelle an die Infrastruktur. Die Modelle sind in digitalen Zwillingen integriert, die als Dienst genutzt werden. Hierdurch ist eine effiziente Adaption von ˜Äderungen an Fertigungsmaschine oder Modell-Methodik möglich. Eine exemplarische Anwendung der Abstraktionsmethode und der Modellierung mittels neuronalen Netzes demonstrieren die Umsetzbarkeit.
Die Arbeit Digitale Markenentwicklung - Analyse des Markenauftritts der Bundeswehr anhand des identitätsbasierten Markenführungskonzepts beschäftigt sich mit der Bundeswehr als Markenkonstrukt. Als theoretische Grundlage dient das identitätsbasierte Markenführungskonzept von F.-R. Esch. Hierzu gilt es außerdem zu untersuchen, inwieweit sich Online-, Hybrid- und Offlinemarken voneinander abgrenzen und wie sich das identitätsbasierte Markenführungskonzept zu diesen verhält. Ziel ist es, die Marke Bundeswehr mit der Markenidentitätstheorie anhand eines ausgewählten Kanals praktisch zu beschreiben, sowie dessen Ergebnisse in Beziehung zur Theorie zu stellen. Kern des Ziels ist es auch festzustellen, wo die Bundeswehr der Theorie folgt und wo sie davon abweicht, woraus sich weiterführende Handlungsempfehlungen ergeben können.
The topic of traditional fashion retailers fighting for their position against growing e-commerce suppliers has been omnipresent in recent years. Therefore, it is important to understand what possibilities modern technology and innovation has to offer, and how these innovative technologies can be leveraged to achieve traditional brick-and-mortar-retailer’s goal of staying relevant and competitive.
The objective of this thesis is to examine and compare the effectiveness of different in-store digitalization concepts and technologies in retail organisations, analyzing different challenges such as the practical implementation in stores, customer adoption and acceptance factors in context of socio-demographic, and measuring the success of the concepts. Also, the current situation will be explored to see what is already being done today and where there is more potential using different approaches and technologies. For this purpose, a variety of studies, papers and other literature will be analyzed and put into context with the research topic.
Concluding the thesis, we find that all technologies and its practical applications affect relevant variables in different models such as TAM, the convenience/social presence model, and the customer decision-making process. Besides that, the socio-demographic variables geography, age and gender all influence adoption and readiness towards technology to a certain extent. Finally, we give examples on how the technologies can influence classic fashion retail KPIs.
Do Meat-Eating Consumers Use Organic Meat to Rationalize the Consumption of Conventional Meat?
(2021)
This thesis explores how meat-eating consumers may be able to rationalize the consumption of conventional meat by believing to substitute a certain amount of it for organic meat. The underlying rationale is that the positive associations elicited by the organic label and the favorable beliefs consumers have formed about organic meat enable them to use it as a moral license. Building on cognitive dissonance theory, this work specifically investigated whether (1) meat-eaters perceive organic meat better than vegetarians and (2) meat-eaters overestimate how much organic meat they consume. German meat-eating and vegetarian participants were recruited for a study (n=156) to answer these questions. The results show, first, that organic was generally rated as better than conventional meat on all dimensions surveyed, and to a greater extent by meat-eating than by vegetarian respondents. Second, meat-eating participants on average reported estimates of organic meat consumption that were significantly higher than the population mean, indicating that consumers may not eat as much organic meat as they believe. Overall, the findings of this study suggest that organic meat might be used to rationalize unsustainable food choices.
Agri-Photovoltaics is a novel renewable energy technology. Amid rising climate change concerns, integrated photovoltaic systems are gaining in importance. Problems such as the increasing scarcity of land and the sealing of fertile soils are becoming more and more serious. Land consumption is often at the expense of agriculture. Farmers are struggling to cope with the ever more difficult conditions due to the effects of climate change. Therefore, the world must increasingly deal with dual use of land. However, especially in Germany the technology of agri-photovoltaics is not yet very advanced. The objective of this thesis is to identify the potential of this technology for the energy transition in Germany. Furthermore, the economic potential for regional farmers in Germany will be elaborated based on an investment appraisal of a vertical agri-photovoltaic system. The application possibilities of agri-photovoltaics are versatile. The work shows that already today farmers in Germany can diversify their income by investing in an agri-photovoltaic system. The costs are higher than for ordinary ground mounted systems, however the land can still be used for agricultural purposes. The investment calculation is carried out in different scenarios. Particularly, the remuneration per kWh as well as the discount factor are decisive for a positive net present value project. The results of this work show that the potential of agri photovoltaics is high for both the energy transition in Germany and the economic benefits for regional farmers. For an increasing expansion of the technology, more precise legislation and appropriate subsidies for agri-photovoltaics are needed.
Currently, the technology is insufficiently covered in German legislation, which needs to be addressed.
Studierende und Lehrende als Kunden wissenschaftlicher Bibliotheken sind im digitalen Zeitalter aufgrund virtueller Angebote nicht mehr wie früher auf physische Bibliotheken angewiesen. Die Tendenz zu „entmaterialisierten Bibliotheken“, stellt komplexe Anforderungen an das Bibliotheksmanagement, mit dem Ziel, die E-Medien als umfassende Services für ihre Zielgruppen sichtbar darzustellen. Ausgehend von diesem Fokus soll das E-Medien-Portfolio der Bibliotheken der Hochschule Furtwangen konsequent an den Bedarfen ihrer Kernzielgruppen ausgerichtet werden. „E-Medien-Service nach Maß“ bedeutet eine komplexe Herausforderung und ist zugleich eine strategische Aufgabe des Bibliotheksmanagements, im Kontext von Studium und Lehre sowie dem Qualitätsmanagement der Hochschule.
Die Arbeit stellt dazu eine qualitative Studie vor, die im Wintersemester 2014/2015 am Campus Tuttlingen durchgeführt wurde. Sie erläutert Hintergrund und Zielsetzung der Untersuchungsfrage, beschreibt die angewandte Methode und das Untersuchungsdesign.
Ziel der Studie war, Nutzungsaspekte und Bedarfe der Zielgruppen Professoren und Studierende der Fakultät Industrial Technologies festzustellen. Darüber hinaus wurde ermittelt, inwieweit das E-Medien-Angebot der Bibliotheken bekannt ist und welche Möglichkeiten bestehen, es besser sichtbar zu machen. Die Ergebnisse aus der Studie wurden in Empfehlungen zur Optimierung des E-Medien-Portfolios zusammengefasst.
Darauf basierend kann ein strategisches Konzept entwickelt werden, welches durch die Untersuchung der Bedarfe und unter Beachtung der Relevanzsysteme ihrer Zielgruppen erfolgreich vom Bibliotheksmanagement eingeleitet werden kann.
This thesis proposes the adoption of renewable energies as a means to foster economicdiversification in oil and gas dependent rentier states. Surprisingly, oil and gas endowment does not always imply wealth and prosperity, mirroring the on-going debate whether natural resource dependent countries are blessed or cursed by their resource abundance.
This thesis seeks to bridge this gap by focussing on rentier states and the question whether rentier states are cursed or blessed. Based on the example of Oman, the proposed approach will be closely assessed. Additionally, the Sultanate’s challenges stemming from natural resource dependence and its preparedness for a post-oil era will be investigated.
Moreover, this thesis will analyze whether a paradigm shift in Oman’s energy sector can mitigate prevailing challenges and support the country’s economic diversification.
These three research questions will be answered through surveying and analyzing literature and data pertinent to the research topic. Findings indicate that rentier states tend to be more vulnerable to the resource curse and the impending fossil fuel depletion as it could cause public outcry and political and economic turmoil. Oman as a rentier state faces a grim post-oil era, fueled by many challenges, including dwindling oil and financial reserves, productivity losses driven by labor market distortions and rapid population growth.
Finally, findings suggest that the combination of economic and energy diversification can have strong positive effects on the Omani economy, such as freeing oil and gas reserves for export revenues, job creation, and private sector strengthening. However, Oman’s renewable energy industry is still in its infancy and faces various challenges, ranging from absent policies and adequate financing to heavily subsidized fossil fuels. As of now, the proposed approach is overly ambitious as the installed renewable energy capacity is too low to create significant employment opportunities or to free oil and gas for export purposes. However, heightened volatilities and economic shocks in recent years were eyeopening for the Omani government and have resulted in stronger efforts to enforce economic development plans. Similarly, the political transition after the death of Sultan Qaboos injected new impetus into Oman’s economy, which will facilitate the diversification of economic bases.
In summer 2015, the FIFA Football World Cup 2006 in Germany was brought back to the public interest due to the publication of corruption allegations against the organising committee, which allegedly bribed FIFA officials in order to bring the World Cup to Germany. Henceforward, the mega-event that was commonly regarded as Germany's summer fairy tale is no longer illuminated in such bright light.
For thin zinc sheets for construction purposes different welding techniques like tungsten inert gas (TIG), plasma arc (PAW) or micro-friction stir (μFSW) welding can be used. However, low ultimate tensile strength (UTS) often leads
to cracking in the weld even at low loads. The characteristics of laser welding make it particularly suitable for joining thin sheets and low-melting materials. Nevertheless, little is known about the weldability of thin zinc sheets by laser welding and the effects of the basic process parameters of laser power and travel speed on the welding process and the UTS of the weld. In this study,
thin zinc sheets were welded at different laser powers and travel speeds. Tensile testing of the welded joint showed, that the UTS and elongation at break increase with the energy input per unit length, but the welding process became gradually unstable and the susceptibility for welding defects increased. This leaves only a few laser powers and travel speeds that produce good welds with respect to UTS and elongation at break. Under these conditions laser welding is an alternative processing technique to
TIG, PAW and μFSW, but needs further investigation to
improve its stability. To implement laser welding in highly
automated production processes further research is required on laser welding of rolled zinc alloys.

Anschließend an die Analyse der Problematiken erarbeitet der Autor dieser Forschungsarbeit ein konzeptuelles Modell zur Bewältigung der geschilderten Problematiken, auf Basis von semantisch beschriebenen, wiederverwendbaren grafischen Visualisierungselementen und den ebenfalls semantisch beschriebenen in die Visualisierung zu überführenden Daten. Besonders hervorzuhebende Erkenntnisse dieser Masterarbeit sind die Identifikation von Qualitätskriterien zur Zielführung einer effektiven Visualisierung gemäß der visuellenWahrnehmung des menschlichen kognitiven Systems, die Notwendigkeit zur Erweiterung der Vokabularmenge der schema.org-Ontologie zur Anwendung der identifizieren Qualitätskriterien und das Auffinden geeigneter Visualisierungselemente sowie das Zuordnen der Daten zu entsprechenden Visualisierungselementen über den Aufbau und Vergleich einer Baumstruktur für sowohl die Daten als auch die der Visualisierungselemente. Diese Forschungsarbeit ist von besonderer Relevanz für Entscheider, Projektmanager und Softwareentwickler, die digitale Informationssysteme mit einer hohen Anzahl an heterogenen Datensätzen und Datenquellen entwickeln.
Durch den vorherrschenden Fachkräftemangel im Gesundheitswesen wird es für Kliniken zunehmend schwerer, qualifiziertes Personal zu finden. Damit sie wettbewerbsfähig bleiben, müssen diese Einrichtungen deshalb Strategien finden, um Personal zu gewinnen und es langfristig an das Unternehmen zu binden. Wichtiger Bestandteil muss es deshalb sein, neue Mitarbeiter effizient und nachhaltig in das Unternehmen zu integrieren.
Diese explorative Arbeit beschäftigt sich mit den Erfolgskriterien nachhaltiger Integration und damit, in welchen Bereichen es Potenzial zur Verbesserung gibt. Das Ziel der Arbeit liegt darin, die Wichtigkeit der nachhaltigen Integration neuer Mitarbeiter aufzuzeigen, sowie auf den Vorteil hinzuweisen, an dieser Stelle zu investieren.
Um einen Einblick in die Integrationsprozesse der Krankenhäuser zu bekommen, wurde im Rahmen der vorliegenden Bachelorarbeit eine Onlinebefragung erstellt und daraufhin Tiefeninterviews geführt, um somit sowohl die Perspektive der Mitarbeiter, wie auch die der Führungsebene zum Thema zu beleuchten. Auf die Datenerhebung aufbauend wurden Handlungsempfehlungen abgeleitet, die es Kliniken erleichtern sollen, neue Mitarbeiter optimal zu integrieren.
Die Resultate der empirischen Forschung belegen, dass die Integration neuer Mitarbeiter in manchen Bereichen bereits gut funktioniert, es aber dennoch Handlungsbedarf besteht. In einigen Einrichtung gibt es bereits Integrationskonzepte, leider mangelt es aber oft an der Umsetzung. Hinzu kommt, dass die zwei wichtigsten Ressourcen - Personal und Zeit - knapp sind.
Einfluss des Klimawandels auf die deutsche Weinindustrie - Zukunftsanalyse für die deutschen Winzer
(2022)
Die vorliegende Bachelorarbeit gibt einen Überblick über die Auswirkungen des Klimawandels auf die deutsche Weinindustrie. Das Ziel war es, die zukünftigen Risiken wie auch Chancen für die deutschen Winzer zu ermitteln und anhand der Ergebnisse Handlungsempfehlungen für die zukünftige Weinindustrie zu entwickeln. Um die Forschungsfragen zu beantworten, wurde eine Szenario- Analyse durchgeführt, welche sich an den deutschen Winzern orientiert. Dabei wurden die Einflüsse betrachtet und anhand dieser wurden unterschiedliche Zukunftsprojektionen erstellt. Die Szenario-Analyse zeigte, dass die deutsche Weinindustrie bei den aktuellen Entwicklungen des Klimawandels deutlich als Gewinner hervorgeht. Dennoch müssen Winzer und andere Akteure der Wein- industrie heute bereits wichtige Entscheidungen treffen und sich den Bedingun- gen anpassen um in der Zukunft die entstehen Chancen nutzen zu können.
Vernetzte Systeme in Fahrzeugen dienen vor allem
der Erhöhung der Sicherheit, Effizienz und dem Komfort im Straßenverkehr sowie der Reduzierung der Umweltbelastung. Ein Beispiel hierfür bietet das sogenannte eCall-System, welches seit März 2018 in allen Neuwägen verpflichtend verbaut werden muss. Dabei setzt das System nach einem Verkehrsunfall einen automatisierten Notruf ab, bei welchem Daten zum Standort, zur Uhrzeit, zur Fahrtrichtung sowie zur Fahrzeugbeschreibung übermittelt werden. Anhand der dadurch resultierenden Erhöhung der Reaktionszeit der Einsatzkräfte um 40 Prozent bis 50 Prozent, können sowohl Menschenleben gerettet als auch eine schnellere Behandlung an Verletzten durchgeführt werden. Trotz der schnelleren Reaktionszeiten ist die Anzahl an verletzten und getöteten Personen im Straßenverkehr annäherungsweise konstant geblieben. Daher stellt sich zunehmend die Frage, ob bestimmte Arten von Verkehrsunfällen, wie z.B. Unfälle
aufgrund von Alkoholeinfluss oder Sekundenschlaf, mit Unfallpräventionssystemen verhindert werden können. Hierzu stellt dieses Paper ein Konzept in Form eines UseCase- und Aktivitätsdiagrammes dar, bei welchem die Überwachung der Vitaldaten mit Hilfe von Biosensoren in das bereits existierende e-Call-System integriert wird. Dabei werden zu Beginn dieses Papers die theoretischen Grundlagen erläutert. Im Anschluss daran werden psychische und physische Faktoren im Straßenverkehr sowie die Messung dieser mit Hilfe von Vitaldaten aufgezeigt. Daraufhin wird das Prinzip des Gehörgangsensor erörtert,der als Grundlage zur Bearbeitung des Konzeptes dient. Nachfolgend wird das Konzept aufgezeigt und erläutert. Am Ende dieses Papers werden die wesentlichen Ergebnisse in prägnanter Form dargestellt und im Anschluss kritisch hinterfragt.

Zur Identifizierung von Einsparpotential und bei der Ausarbeitung kostengünstigerer Alternativen werden diverse Methoden des Lean Managements genutzt.
Over the past few decades, there has been an increasing amount of academic literature recognizing the significance of innovation systems. Entrepreneurship is an important component of an innovation system, contributing to the enhancement of regional as well as national innovation. The transfer of knowledge and technology between science and the economy has become particularly important to reinforce overall innovation performance. Today, universities and other institutions of higher education play a crucial role in the system of innovation and have evolved as active and highly relevant participants in the innovation system. Therefore, various supportive measures have been developed to increase the level of innovation at universities and to drive entrepreneurial activities. However, due to the ever-growing entrepreneurial support environment and the great variety of support programs,the distinction between support measures has become unclear. Consequently, the main objective of the present research work is to contribute to the overall understanding of supportive measures at German universities and other institutions of higher education.
Eight experts were interviewed to ensure the compilation of meaningful data. The research findings highlight the importance of a solid network of external experts as well as collaboration with other entrepreneurial institutions. Moreover, the research results indicated that an organizational structure with decentralized decision-making processes and a greater scope of actions enhances operational efficiency. While considering the indistinctness of different support programs and specific terms, although some significant differences were evaluated, overall, the results present a clear tendency toward a more cautious use of specialist terms, therefore substantiating the missing preciseness.
In der vorliegenden Arbeit werden empirische Ergebnisse aus einer Patientenbefragung und zwei Experteninterviews zu dem Thema Patientensicherheit und Versorgungsqualität im Bereich der Knieendoprothetik miteinander verglichen und ausgewertet. Zusätzlich werden die Ergebnisse dieses Vergleichs mit der Literatur verglichen und analysiert. Die verwendete Literatur besteht aus aktuellen Fachbüchern, Fachberichten sowie Fachpublikationen. Dabei sollen die zukünftigen Herausforderungen auf dem Gebiet der Knieendoprothetik herausgearbeitet und eine Patientenempfehlung in der Behandlung von Kniearthrose ausgesprochen werden.
Für die Patientenbefragungen und die Experteninterviews ist die sog. „Mixed-Methods“ – Methode angewendet worden, wobei es sich um die Kombination einer quantitativen (Patientenbefragung) und qualitativen (Experteninterview) empirischen Forschungsmethode handelt. Dabei sind insgesamt 31 Patienten, im Durchschnitt ein Jahr postoperativ, nach Einsatz einer Knieprothese anonym zu ihrem Beschwerdebild sowie ihrer Zufriedenheit mittels eines schriftlichen Fragebogens befragt worden. Anschließend sind zu kritischen Ergebnissen der Patientenbefragungen zwei Experten auf dem Gebiet der Knieendoprothetik per digitalem Interviewleitfragen, und einer davon auch persönlich, befragt worden.
Das Kniegelenk ist eines der komplexesten und kompliziertesten Gelenke unseres Körpers. Es ist das größte Gelenk unseres Körpers und verbindet die größten Knochen des Menschen miteinander. Umso wichtiger ist es, eine möglichst physiologische Wiederherstellung des Kniegelenks zu erreichen unter Beachtung einer genauen Selektion von geeigneten Patienten für den Kniegelenksersatz, geeigneter patientenindividueller Prothesekomponenten, der richtigen Operationstechnik sowie erfahrener Operateure. Verschiedene Akteure im Gesundheitswesen sollen genau dies regulieren um somit die Patientensicherheit und Versorgungsqualität zu gewährleisten. Eine verpflichtende Teilnahme am Endoprothesenregister Deutschland, um alle Knieendoprothesenverläufe zu dokumentieren, muss in Zukunft zur Pflicht werden. Mindestmengen, Ausbildungsanforderungen und definierte Behandlungsleitlinien müssen allem voran für die Operateure im Gesundheitssystem etabliert werden.
Durch die Patientenbefragung, das Experteninterview und Angaben in der Literatur hat sich eine sehr hohe Korrelation zwischen Übergewicht und der Entstehung von Kniearthrose ergeben. Eine stärkere Aufklärung in der Öffentlichkeit bzgl. Übergewicht und deren Folgeschäden durch die Politik wäre hier wünschenswert. Die Patienten müssen aktiv (z. B. Physiotherapie, Muskelaufbau) mehr für ein zufriedenstellendes Behandlungsergebnis tun, sowohl prä- als auch postoperativ, egal ob zur Schmerzreduktion oder zur Wiedererlangung von Funktionalität, Kraft und Sicherheit des Kniegelenks. Die Experten fordern eine bessere Aufklärung bzgl. einem realistischerem Behandlungsergebnis, was die Patientenzufriedenheit und Entscheidungsfindung für oder gegen einen Knieersatz maßgeblich mit beeinflusst.
Sehr vielversprechende Therapieansätze haben sich für die Patientenempfehlung ergeben. Dabei sei ganz besonders die SYSADOA-Medikamentengruppe („symptomatic slow acting drugs in osteoarthritis“) und die knorpelrehabilitativen und knorpelregenerativen Therapieverfahren („Tissue Engineering“, ACT, etc.) zu erwähnen.
Die Diagnose der Arthrose im frühen Stadium und der stetig wachsende Fortschritt im Bereich der Medizin, Biomolekularmedizin und Materialwissenschaften könnten die Therapien im Bereich der Knorpelrehabilitation im Hinblick auf die Kniearthrose revolutionieren.

Die Biografie- und Erinnerungspflege stellt eine Behandlungsform für die unheilbare Demenzerkrankung dar. Hierbei wird versucht durch Aktivitäten, welche einen Bezug zu der Vergangenheit des Menschen mit Demenz haben, Erinnerungen auszulösen. Dies hilft der an Demenz erkrankten Person ihr Identitätsgefühl zu festigen.
Im Rahmen dieser Bachelorarbeit wurde eine innovative Anwendung entwickelt, welche interaktive und multimediale Bilder für die Biografie- und Erinnerungspflege bereitstellt. Mit diesen Bildern kann der Mensch mit Demenz interagieren, indem er auf einzelne Objekte drückt und daraufhin ein thematisch passendes Medium präsentiert wird. Die interaktiven Bilder werden automatisch, mittels Machine Learning, erstellt. Des Weiteren wurde ein Recommender System implementiert, welches basierend auf den Präferenzen des Menschen mit Demenz, Inhalte für eine Biografie- und Erinnerungspflegesitzung vorschlägt.

Die Anforderungen sind hierbei Herstellkosten im einstelligen Bereich, eine Auflösung von ca. 0,1° und der Drehgeber soll auf Arduino-Basis betrieben werden. Ziel dieser Arbeit ist es mit Hilfe von Simulationen die Grenzen des Systems festzulegen, mit diesen Erkenntnissen einen Prototyp zu erstellen und diesen anschließend mit einem Messgerät zu validieren.
Die Firma XYZ benötigt einen neu entwickelten Tragarm für die folgende Generation der Schweißzange. Die Konzeption und Entwicklung des Tragarms findet unter den Gesichtspunkten der Fertigungs- und Montagekosten, sowie Nutzerfreundlichkeit und Design statt. Die Nutzerfreundlichkeit und das Design wird mit Hilfe des aktuellen Tragarms und einer Benchmarkanalyse optimiert. Die Benchmarkanalyse zeigt dabei die unterschiedlichen Ansätze der am Markt existierenden Produkte. Die Bewertung der Konzepte findet mit Hilfe einer Nutzwertanalyse statt. Durch die gewichteten Ergebnisse und Interviews mit den Projektbetreuern können Schwachstellen aufgedeckt und weitere Optimierungsmöglichkeiten gefunden werden. Die Konstruktion wird mit analytischen Methoden zur Berechnung und Auslegung ergänzt. Das Ergebnis ist ein Tragarm, dessen Reichweite und Arbeitsraum den Kundenbedürfnissen entspricht. Unter Berücksichtigung der Tragfähigkeit, Kippsicherheit und Nutzerfreundlichkeit weist der Tragarm ein eigenständiges Design mit Kippmechanismus auf, welches eine stufenlose Anpassung des Arbeitsraumes ermöglicht.
Im Rahmen dieser Master-Thesis wurden Verfahren zum Transfer eines Arrays kleiner Dies (unverkapselte Chips) mit einer Kantenlänge von 250 μm bis 300 μm untersucht. Die Dies sollten hierbei von UV-lichtempfindlicher Folie selektiv abgehoben und auf einem Zielsubstrat abgesetzt werden. Als Verfahren wurde die Stempeltechnologie gewählt. Zum Aufnehmen der Dies wurden Stempel aus Silikon gegossen. Als Substrate zum Absetzen der Dies wurden Gläser mit Zucker beschichtet. Zur Überprüfung des Verfahrens wurden Zugversuche durchgeführt. Die senkrechte Abzugskraft der verwendeten Folie und der Silikonstempel wurde ermittelt. Durch Abzugstests der Folie im belichteten und unbelichteten Zustand wurden die genutzten Belichtungsprozesse überprüft. Das Umsetzen wurde mit gesägten Stücken eines Siliziumwafers durchgeführt. Es konnte nachgewiesen werden, dass das Umsetzen mit Silikonstempeln möglich ist und die erzeugten Kräfte hierfür ausreichen. Die Herstellung und Vorbereitung der gesägten Siliziumwürfel erwies sich hierbei als kritischer Prozess, was die Reproduzierbarkeit der Umsetzung stark beeinträchtigt.

Diese Bachelorarbeit beschäftigt sich mit der Erstellung eines strategischen Marketingkonzepts für das B-to-B IT-Serviceproviderunternehmen agilTech Information Technologies GmbH. Durch mangelnde strategische Ausrichtung und die vorherrschende Projektarbeit als Individualsoftware entwickler und IT-Berater, sah sich das Unternehmen bisher einem großen Absatzrisiko und einer volatilen Nachfrage ausgesetzt. So hat sich das Unternehmen opportunistisch am Markt bewegt, keine konkreten Unternehmensziele definiert und konzeptlose Marketingmaßnahmen ohne Zielgruppenbestimmung durchgeführt. Ziel dieser Arbeit ist somit die Entwicklung eines strategischen Marketingkonzepts, um agilTech wettbewerbsfähig am Markt zu positionieren, mehr Projektanfragen zu generieren und so ein strategisches Unternehmenswachstum im fragmentierten Individualsoftwaremarkt zu ermöglichen. Der Lösungsansatz dieser Arbeit basiert auf Taylor’s (2015) strategischem Marketingplanungsprozess, der sich in die Phasen Ziele und Marktanalysen, Strategieentwicklung und operatives Marketing einteilen lässt. Als Ergebnis entstand eine Marketingstrategie, Servicemarketing Mix-Maßnahmen und Kommunikationsmittel wurden identifiziert sowie Handlungsvorschläge unterbreitet. Für die Organisation und Implementierung der Servicemarketing Mix-Maßnahmen wurde ein detaillierter Plan erstellt, für die Marketing-Kontrolle je Servicemarketing Mix-Maßnahme mehrere Key Performance Indicators definiert und Messinstrumente vorgestellt. Damit das erarbeitete, strategische Marketingkonzept positive Resultate erzielen kann, ist jedoch Top Management Support in Form von Engagement sowie zeitliches und finanzielles Investment notwendig.
Organized, competitive computer gaming, also referred to as eSports, are emerging sports within the sports entertainment industry. The industry generated almost 700 million U.S. Dollar in revenue and leading eSport titles attract millions of viewers to their events. This study aims to explore eSport live broadcasts of four leading titles and their appeal to be used as a communication media for marketers. It adopted secondary data from academic and scientific studies, journals and books from the fields of eSports, business and sports management to examine commercials, product placements, sponsorships and celebrity endorsements in regards of their applicability and effectiveness within eSports. Quantitative research in form of a survey among eSports viewership was carried out to gather data on viewership consumption patterns and perceptions towards said communication instruments and their effectiveness.
Findings suggest that the effectiveness of commercials rely on the timing shown during broadcasts. Product placements can be applied in many ways and show high effectiveness in terms of brand recognition in any form. Celebrity endorsements are highly ambiguous in terms of their applicability and effectiveness.
The population in the U.S. is getting more and more characterised by cultural diversity. “By 2020, minority groups will account for the majority of the U.S. population.” Especially, the Hispanics are becoming more significant as they represent the biggest minority. To successfully adapt to the changing composition of the population, marketers should adapt and segment the marketers according to the individual taste and preferences of the targeted consumers. Nevertheless, some companies ignore these developments and still use mass marketing to reach the consumers. In the following, the impact and importance of Hispanic-Americans will be examined. Is the Hispanic population worth pursuing? By giving some information on ethnic marketing and ethnic groups, the background and the sub-cultures of Hispanic Americans, evoking the characteristics of the Hispanic shopper and the importance of the Hispanics for the U.S. market, the previous question can be clarified at the end.
In this thesis, new methods for text classification are examined and compared to the current software of the DNB. Due to technical changes in the area machine learning in recent years, improvements in text classification have been achieved. The objective is to improve the subject groups allocation of the DNB and to allow a hierarchical classification based on the DDC system. The decision was made on the HDLTex tool, as the structure of the DNB data set and the DDC system, which supports a hierarchical classification, are perfectly designed for it. The use of RNN networks on both hierarchical levels improved the current software situation. Furthermore, the approach was examined, if a combination of the predictions of the two hierarchies levels leads to an additional improvement, which, however, produced a negative result. Both beginners and experts find themselves as readers of this master's thesis in the target group again.
In dieser Arbeit werden neue Verfahren zur Textklassifizierung untersucht und der aktuellen Software der DNB gegenübergestellt. Durch technische Veränderungen im Bereich Machine Learning in den letzten Jahren, konnten Verbesserungen in der Textklassifizierung erzielt werden. Dabei soll die Sachgruppenvergabe der DNB verbessert und anhand des DDC Systems eine hierarchische Klassifizierung ermöglicht werden. Die Entscheidung fiel auf das HDLTex Tool, da die Struktur des Datensatzes der DNB und das DDC System, welche eine hierarchische Klassifizierung unterstützt, perfekt darauf ausgelegt sind. Durch die Nutzung von RNN Netzen auf beiden Hierarchieebenen konnte eine Verbesserung zu der aktuellen Software erzielt werden. Weiterhin wurde der Ansatz untersucht, ob eine Kombinierung der Vorhersagen der beiden Hierarchieebenen zu einer aufbauenden Verbesserung führt, welches jedoch ein negatives Ergebnis hervorbrachte. Sowohl Anfänger als auch Experten finden sich als Leser dieser Masterarbeit in der Zielgruppe wieder.
University-Industry Collaboration (UIC) is considered by academics and industry as a vital factor that has the power to both positively and negatively impact the open innovation (OI). To contribute to the literature and to identify challenges as well as to conceptualize some recommendations to help industries, this thesis raised a question:
what are the challenges of UIC and what recommendations can be made to solve the challenges. The main research objective was to recognize the determinants of UIC challenges. An empirical study was conducted in order to give an answer to the research questions and to meet the research objective. This research explicitly focused on students/interns and internships to analyze and to discover the challenges and solutions since students or internships are the least researched area in the field of UIC research. Participants were personally contacted with the survey link that was created online to conduct explorative research with the help of close-ended (quantitative) and open-ended (qualitative) questions. The results reveal that there are numerous challenges students face during the internship and thus these most likely hinder the successful UIC and ultimately successful OI. According to the results obtained from both quantitative and qualitative sections obvious and major challenges lie in innovation mediators ‘organizational culture’. From the quantitative result perspective only, major challenges are in the area of absorptive capacity and supervisors' support, internalization, and trust. Similarly, from the qualitative results perspective only, major challenges are bad crisis management, communication, and hierarchical structure.
Football is unambiguously the national sport in Germany. No other sport attracts more people and has the power to connect more people of different ages, nationality or status. In football everyone is equal at least for 90 minutes. Having one favourite football club means having an emotional connection to it with celebrating the wins and suffering when the team loses. The German Bundesliga in particular is a magnet for fans coming into the stadium.
Prior research on choice in context demonstrated extremeness aversion to be very effective on consumers’ purchasing behaviour. However, it seems that previous studies have neglected to investigate the impact of the spatial arrangements of choice architectures on consumers purchasing behaviour. Based on indications of prior research, we pursued to demonstrate in this study that consumers who are uncertain regarding their
preferences tend to search for alternatives in the middle of a choice architecture. Therefore, we hypothesized that an alternative, positioned in the middle of a choice architecture, will present a relatively higher choice share. To research this hypothesis we conducted an online survey mainly in Central Europe, which involved a total number of
901 respondents at the age between 15 and 95. The study’s results demonstrate that the decision making of the majority of the participants is heavily influenced by a choice architecture’s spatial arrangement. It became evident that the choice share of one
alternative was higher when presented in the middle of a choice architecture than when presented in the periphery.
