Digital transformation is now reaching into topics like End-of-life Care, Funeral Culture, and Coping with Grief. Those developments are inevitably accompanied by the growing challenge to design IT systems that are appropriate and helpful for the stakeholders involved. Our aim in this paper is to further introduce the rather new combined research field of Socioinformatics and Thanatology (the scientific study of death and dying) and to present it with the first results on which requirements to consider for the design of digital tools within ‘Thanatopractice’. By using Participatory Design and the Sustainability Awareness Framework (SusAF) in the context of three workshops on socio-technical systems (Online Pastoral Care, Virtual Graveyards, and AI Memory Avatars), we want to sensitize software practitioners to the multidimensional impacts of their products and services in a field, which the participants in the workshops often described as “highly sensitive”.
The purpose of this study is to diffuse knowledge about the limited roles women still play in Nigeria, as opposed to the roles they could be playing if they were to be empowered,
especially in terms of local and national security. The research questions examined the different ways in which women in Nigeria are suffering the omnipresence of patriarchal beliefs and the norms they entail, which interviews with a sample of nine Nigerian women have testified for. It further analyzed the possible interdependence between patriarchy and insecurity levels, and how empowering women could help building peace in the region. Three experts on the topic were interviewed, and testified for this correlation between women and security, while also pointing out the need for governmental support in terms of financing and policing this inclusion of women. The paper finally proposes a set of recommendations to the different stakeholders of Nigeria, from the civil society and Non-Governmental Organizations (NGOs) to the Government itself, on how to reach empowerment and peacebuilding in a sustainable way. Structured mainly on the social and cultural determinants of women’s roles in Nigeria, the study revealed that such determinants need political and legislative will if they are to improve. There is an urgent need for the Nigerian Government to take responsibility for the insecurity the country is facing and acknowledge how this insecurity is curbing any improvement towards both women empowerment and peacebuilding at the national and regional levels. Some of the recommendations include the promotion of dialogue among stakeholders, the implementation of sport programs to diffuse values of tolerance and empowerment, and the alteration of discourse around women and girls to change the conceptualization of power and therefore the roles they play in the society.
Zur Stabilisierung der Konjunktur im Zuge der Covid-19-Krise hat die Bundesregierung Deutschlands mit der vom 01. Juli bis 31. Dezember 2020 eingeführten temporären Mehrwertsteuersenkung auf ein noch neuartiges konjunkturpolitisches Instrument zurückgegriffen. Dieses ist zentraler Teil eines mit 130 Milliarden dotierten Konjunkturpakets.
Ziel dieser Arbeit ist, die Wirksamkeit zentraler Elemente der Konjunkturpolitik anhand der damit verbundenen Anforderungen zu untersuchen und die Mehrwertsteuersenkung in diesem Kontext auf ihre Eignung zur Konjunkturstimulierung zu überprüfen. Zur empirischen Untersuchung wurden Experteninterviews mit Wirtschaftswissenschaftlern und betroffenen Verbänden durchgeführt. Die ersten richtungsweisenden Erkenntnisse aus den Interviews, Praxisbeispielen und bestehender Theorie zeigen, dass die Mehrwertsteuersenkung zwar zeitnah und temporär umgesetzt werden konnte, jedoch als wenig zielgerichtet und effektiv zu bewerten ist. Der von der Bundesregierung erhoffte Konjunktureffekt ist als gering zu beurteilen und kam Krisengewinnern stärker zu Gute als besonders betroffenen Branchen. Im Kontext der pandemiebedingten Krise wird zudem die grundsätzliche Wirksamkeit nachfrageorientierter Maßnahmen sowie die praktische Handhabung und zeitliche Koordinierung der Mehrwertsteuersenkung kritisch hinterfragt.
Compared to relational databases, graph database systems provide a novel way of processing and analyzing highly interconnected data. Due to their unique properties, graph databases embody an interesting area of research in academic circles. For this reason, this work is fundamentally concerned with examining the state of the industry and current challenges. In this regard, we revisit the basic concepts and highlight the tremendous heterogeneity of available systems using the example of differing path semantics. Based on this insight, we explore algorithmic advancements for graph query processing regarding path finding and worst-case optimal joins. Subsequently, we discuss issues regarding performance and support for graph analytics. Finally, we provide an overview of GQL, a joint standardization effort towards unification of property graph databases.
The longevity industry has been expanding for several years now, with the goal to prolong not only the lifespan of people but also their healthspan. One of the most remarkable techniques in the field is the CRISPR Cas-9 gene-editing tool, which owing to its flexibility and efficiency, allows humans to develop new treatments to prevent or cure a great variety of diseases. This paper aims to forecast the future state of the CRISPR Cas-9 technology in Germany in 2035 by using the INKA 4 scenario manager software. A total of five areas of influence –– i.e. scientific, economic, demographic, ethical, and legal –– were identified. From those, 11 descriptors were created based on relevant scientific literature and were introduced in the INKA software to develop the scenarios. This process resulted in three clearly differentiated scenarios that exhibit high probabilities of a positive outlook for the CRISPR-Cas9 technology in Germany by 2035.

Vergleicht man ein Automatisierungssystem mit dem menschlichen Körper, dann sind die Rechner (PC, SPS, Mikro-Controller) das Gehirn, die Signalleitungen die Nervenbahnen, die Sensoren die Augen und Ohren, die Aktoren die Muskeln, die Starkstromleitungen die Adern. Alle Teile sind wichtig und müssen zueinander passen.
For many practitioners, considering sustainability during a software development project is a challenge. The Sustainability Awareness Framework (SusAF) is a tool for thinking through short, medium-and long-term impacts of socio-technical systems on its surrounding environment. While SusAF has been used by several companies, is not widely adopted in industry yet. In this Vision Paper, we discuss the options for extending the reach of SusAF and what it would take to evolve SusAF into a (de-facto) standard
Vergleich maschineller Lernalgorithmen in Anwendung auf die 3D-Gestenerkennung per Leap Motion
(2017)
Die Gestensteuerung ermöglicht eine intuitive sowie natürliche Interaktion zwischen Mensch und Maschine. Um die Bewegungen des Nutzers im dreidimensionalen Raum erkennen und klassifizieren zu können, sind Sensoren nötig, deren Signale es gilt zu verarbeiten. Diese Verarbeitung geschieht mittlerweile überwiegend durch Algorithmen des maschinellen Lernens, welche mit Hilfe von eingelernten Daten selbstständig Vorhersagen über neue Eingabesignale treffen können.
In dieser Arbeit werden die Eigenschaften und die damit zusammenhängende Erkennungsgenauigkeit solcher Algorithmen untersucht und verglichen. Dabei sollen die Support Vector Machine und das neuronale Netz berücksichtigt werden, welche mit Hilfe der Open Source Bibliotheken TensorFlow und scikit-learn implementiert wurden. Als Untersuchungsgegenstand dienen die Positionskoordinaten von insgesamt 350 dynamischen Gesten. Diese wurden mit dem Tiefenensor Leap Motion mittels einer eigens entwickelten Software aufgezeichnet und entsprechend vorverarbeitet. Auf diese Software, sowie den Prozess der Datensammlung, der Vorverarbeitung und letztendlich der Klassifizierung wird in der Arbeit ausführlicher eingegangen.
Die durchgeführten Tests zeigen, dass beide Algorithmen in der Lage waren eine Erkennungsgenauigkeit von bis zu 93,40% zu erreichen. Die Support Vector Machine schnitt durchschnittlich mit 87,15%, gegenüber dem neuronalen Netz mit 80,47%, besser ab.
Das stoffliche Recycling von Handwerkzeugen stellt eine Herausforderung dar. Hierzu ist eine Trennung der Werkstoffverbunde in ihre Einzelkomponenten erforderlich. Im Rahmen dieser Arbeit werden unterschiedliche mechanische, thermische und chemische Verfahren zusammengefasst, mit welchen dieses Ziel erreicht werden kann. Um den Produktionsprozess der Handwerkzeuge noch ressourcenschonender zu gestalten und die Verwendung von rohölbasierten Kunststoffen zu reduzieren, werden im zweiten Teil der Arbeit Biokunststoffalternativen identifiziert und hinsichtlich ihrer Eignung für die Produktion von Handwerkzeugen untersucht.
Using 15N‐Ammonium to Characterise and Map Potassium Binding Sites in Proteins by NMR Spectroscopy

In der vorliegenden Masterarbeit wurden verschiedene Ansteuerungsstrategien für den Betrieb von dreiphasigen Active-Neutral-Point-Clamped- (ANPC) Mittelspannungs-Netzumrichtern mit Siliziumkarbid (SiC) Halbleiterschaltelementen untersucht. Durch die Vielzahl an aktiven Schaltelementen können bei der ANPC-Topologie zur Modellierung des gewünschten Ausgangssignals zahlreiche unterschiedliche Ansteuerungsstrategien eingesetzt werden. Je nach gewählter Ansteuerungsstrategie können so unter anderem die Faktoren Schalt- und Durchlassverluste, Wirkungsgrad, Verlustverteilung, Schalter- und Ausgangsschaltfrequenz, der Oberschwingungsanteil des Ausgangssignals, sowie die maximale Spannungsbelastung der Halbleiter beeinflusst werden.
Neben der elektrotechnischen Beschreibung der aktuell eingesetzten Umrichter-Technologien wurden in dieser Arbeit primär aus aktuellen Veröffentlichungen und Dissertationen verschiedene Möglichkeiten für die Ansteuerung von ANPC-Umrichter zusammengetragen und insgesamt sieben Sinus-Pulsweiten-Modulationsstrategien (S-PWM) im Detail untersucht. Hierbei wurde für jede vorgestellte Modulationsstrategie das Grundfunktionsprinzip aufgezeigt und analysiert, sowie die sich daraus ergebenden Vor- und Nachteile herausgearbeitet.
Anschließend wurden alle vorgestellten S-PWM-Strategien in der Schaltungssimulationssoftware PLECS implementiert und diese in verschiedenen Betriebszuständen simuliert. Die Simulation ergab, dass sich bei der ANPC-ALD-Strategie eine bestmögliche Verlustverteilung zwischen den Halbleiterelementen einstellt, bei der ANPC-OOZS-Strategie die geringsten Durchlassverluste entstehen und bei den Strategien ANPC-DF, -12, -R2:1 und -SSLD im Bereich der Nulldurchgänge des Ausgangssignals an den inneren Halbleitern kurzzeitige kritische Überspannungen auftreten. Bei den Strategien ANPC-11-Sync, -ALD und -OOZS treten dagegen keine Überspannungen an den Halbleitern auf.
Ausgehend von diesen Simulationsergebnissen wurden die Strategien ANPC-DF, -ALD und -OOZS für den potentiellen Einsatz in Mittelspannungsumrichtern ausgewählt, auf einem FPGA-Board implementiert und damit eine geeignete Niederspannungstestplattform in Betrieb genommen. Durch praktische Messungen auf dieser Testplattform konnten die Simulationsergebnisse in einem ersten Schritt verifiziert werden. Sowohl das erstellte Simulationsmodell als auch die in Betrieb genommene Testplattform können somit zukünftig für weitere Untersuchungen im Bereich der ANPC-Umrichter-Ansteuerungsstrategien eingesetzt werden.

Im Rahmen dieser Bachelorarbeit wird untersucht, ob kulturelle Faktoren einen Einfluss auf das Verhältnis zwischen in Deutschland lebenden türkischstämmigen Anwälten und Mandanten haben. Hierzu wird die ethnische Identität von Deutsch-Türken im Zusammenhang mit Generationsunterschieden untersucht. Zudem werden Akkulturationsmodelle, Kommunikationstheorien sowie Ziele und Möglichkeiten des ethnischen Marketings definiert.
Durch Anwendung qualitativer und quantitativer Forschungsmethoden werden jeweils aus Anwalts- und Mandantensicht die ethnische Identität sowie die für die Präferenz eines türkischstämmigen Anwalts relevanten Faktoren einzelner Einwanderergenerationen ermittelt.
Die Ergebnisse zeigen, dass die Anwalts-Mandanten-Beziehung stark von kulturellen Aspekten beeinflusst wird und dass Änderungen im anwaltlichen Ethno-Marketing notwendig sind, da diese nicht von türkischstämmigen Mandanten wahrgenommen werden.

The Sustainable Development Goals (SDGs) of the United Nations focus on key issues for the transformation of our world towards sustainability. We argue for stronger integration of the SDGs into requirements and software engineering and for the creation of methods and tools that support the analysis of potential effects of software systems on sustainability in general and on SDGs in particular. To demonstrate one way of undertaking this integration, we report on how the Sustainability Awareness Framework (SusAF -- a tool developed by the authors of this paper) can be mapped to the SDGs, allowing the identification of potential effects of software systems on sustainability and on the SDGs. This mapping exercise demonstrates that it is possible for requirements engineers working on a specific system to consider that system's impact with respect to SDGs.
Software engineering, as a central practice of digitalization, needs to become accountable for sustainability. In light of the ecological crises and the tremendous impact of digital systems on reshaping economic and social arrangements - often with negative side-effects - we need a sustainability transformation of the digital transformation. However, this is a complex and long-term task. In this article we combine an analysis of accountability arrangements in software engineering and a model of sustainability transformations to trace how certain dynamics are starting to make software engineering accountable for sustainability in the technological, cultural, economic and governance domains. The article discusses existing approaches for sustainable software engineering and software engineering for sustainability, traces emerging discourses that connect digitalization and sustainability, highlights new digital business models that may support sustainability and shows governance efforts to highlight “green and digital” policy problems. Yet, we argue that these are so far niche dynamics and that a sustainability transformation requires a collective and long-lasting effort to engender systemic changes. The goal should be to create varied accountability arrangements for sustainability in software engineering which is embedded in complex ways in society and economy.
The thesis introduces a case study research presenting the transfer pricing problem of a selected MNE. Hereby, the researcher derives an appropriate method for the case and concludes with a comparison of theory and practice. The theoretical part of the thesis evaluates existing transfer pricing methods as explained by the OECD, Germany and the USA. The second part is about the choice of the research methodology, case study research and expert interview.
The third part first introduces the case study, analyzes a theoretical framework of the transfer pricing process and evaluates the existing transfer pricing methods, which allows for the derivation of the most appropriate transfer pricing method for the case. The fourth part concludes the research by applying the derived transfer pricing method, the Cost Plus Method, to the particular case study. By combining theoretical and practical approaches, a solution to the problem is determined.
This study explores the complex dynamics influencing the establishment of secondary
vocational exchange programs, with an emphasis on identifying the barriers and
facilitators in this process. Adopting a qualitative research approach, the study seeks to
capture the rich, nuanced experiences of stakeholders and provide context-specific
insights. Semi-structured interviews were conducted with professionals, administrators,
and officials associated with German and United States Vocational Education. Employing
a two-tiered participant selection strategy, a range of perspectives were captured. The
data were analyzed using an inductive approach to thematic analysis, aiming to identify
underlying patterns and themes. Preliminary findings indicate that funding, policy and
governance challenges, educational structures, administrative elements, corporate
attitudes, and socio-cultural influences play significant roles in the establishment of these
exchange programs. The research also underscores the importance of participant
preparedness, program structure, stakeholder interest and engagement, diversity and
inclusion, and innovative program approaches as vital facilitators. These insights can
influence the development of policies and practices for future secondary vocational
exchange programs, thus contributing meaningfully to the larger conversation
surrounding vocational exchange programs and international educational partnerships.
In this paper, we present a study on the utilization of smart medical wearables and the user manuals of such devices. A total of 342 individuals provided input for 18 questions that address user behavior in the investigated context and the connections between various assessments and preferences. The presented work clusters individuals based on their professional relation to user manuals and analyzes the obtained results separately for these groups.
The Revive Turbo Cleaner is a cleaning fluid which removes carbon deposits from inside petrol or diesel engine systems. It is distributed internationally through wholesalers and sales agents to workshops and private car owners. After the acquisition of Revive Automotive Solutions Ltd by Bartec Auto ID Ltd in summer 2016, the new owners decided to further develop the brand and to move into the promising German automotive aftermarket, as the Cleaner had shown good sales figures in the home market UK and in a number of international markets. This paper examines environmental factors influencing the German marketplace, analyses Revive’s actual customer segments including consumers and business clients, provides profiles of its competitors and substituting technologies, regards the characteristics of the specific industry and defines the product’s qualities in order to draw a conclusion on the appropriate Marketing Mix to employ for the German market. In advance to the analytical work, the paper critically considers the range of theoretical frameworks used for the analysis, namely PESTEL, Porter’s Five Forces Analysis, the SWOT Analysis and the Marketing Mix in order to define and update original concepts as wells as adapt them to the research requirements.
The Present and Future of a Digital Montenegro: Analysis of C-ITS, Agriculture, and Healthcare

In two experiments, this empirical research examines consumers’ willingness to pay and the likelihood of purchase decisions by thoroughly investigating the neural, behavioral, and psychological properties of packaging design. A general theory is tested by functional magnetic resonance imaging (fMRI) and a NeuroPricing online survey on consumer behavior using the example product Tassimo. Hypotheses are tested with 592 German consumers who evaluated the packaging of Tassimo coffee. A closer look at the neural data from the brain imaging experiment shows that uncertainty can arise among consumers with regard to sustainable packaging and this can have a negative impact on the purchase decision and willingness to pay. The results from both experiments show that it is not possible to make a holistic statement as to which sustainable or enjoyment-focused packaging design increases the likelihood of a purchase decision or the willingness to pay. Implications for future packaging design research and underlying complexities with sustainable packaging are discussed.
Based on the history of office design, the changing technological environment and current business challenges, the physical workplace is an important aspect of the employee experience. The aesthetics of the work environment are one aspect that influences well-being and satisfaction on many different levels. This thesis provides a holistic and comprehensive perspective on the topic, including important influential factors from several scientific disciplines.
Two main dimensions of influence on the employee experience are considered. The direct- affective dimension deals with findings mostly from environmental psychology and neuroscience, which includes the impact of internal environmental quality and other psychological effects. Despite not always being consciously recognized, aesthetics and sensual perception have strong implications for the psychological well-being of organizational members.
The indirect-cognitive dimension deals with the work environment as an expression of organizational culture and the resulting implications of aesthetic considerations and the related symbolic and functional dimensions of the physical work environment. Common organizational artifacts and themes are explored as examples of the influence of aesthetic considerations for workplace design.
Next to the employee perspective, the managerial perspective and important implications, restrictions and issues for organizations in the creation and operation of workspaces are also considered.
Empirical research has been conducted to evaluate the application of aesthetic considerations and related issues in practice. Four expert interviews provide insight into the perspective of workplace design professionals on the aesthetics and related aspects of design, implementation processes and employee experience.
The aesthetic dimension of workplace design is often not actively considered by organizational members and management, but the research conducted in this work provides far-reaching evidence for the potential benefits of more considerate design choices for the aesthetics and beauty in the workplace. Using measures on both the direct and indirect levels of influence, the well-being and satisfaction of employees can be increased, and the attitudes and feelings held towards the organization can be improved. The importance of the interrelated fields of organizational culture and cultural change is explored. In addition, practical recommendations for the optimization of the aesthetical dimension of workplace design are offered at the conclusion of this work.
Many companies are struggling with the decision of whether they should invest resources in the new app TikTok to communicate and develop their employer brand. Therefore, this thesis addresses, the question: Should German companies invest in TikTok as an employer branding tool? As this topic is not well researched yet, this work is based on individual opinions of HR professionals and opinions on the internet. There is no scientific verification of the accuracy of the statements made in this paper.
To answer this question, interviews with 14 German HR experts have been conducted. Afterwards, the interviews have been summarized and evaluated. The results show that the answer to the research question depends on several factors.
TikTok is considered as a suitable tool if the company’s DNA correspond to that of the application and if enough personal resources are available. Also, if the target group and their needs match the young audience and if the company has already gained experiences on social media. Furthermore, the uploaded content should be authentic and involve motivated representatives of the target group (age 16 to 24). The company must give those employees full support, trust and freedom. Nevertheless, they should also invest in their training and let them know what is desired. The content on TikTok should be informative, short, in the language of the audience and the company should act as an adviser. Employer branding content should be published infrequently and only once a community has been built. The app should be understood as an awareness channel and it should not be expected to bring many applicants immediately. Firms should weigh the positive and negative sides and use the above factors to decide whether TikTok fits their own company.
The success of TikTok can be explained, for example, due to the dopamine release when watching videos on social media and the complex algorithm behind the app, which filters only relevant videos for the individual preferences of each user. Moreover, other hormones such as adrenalin and oxytocin are released, as well. The variety of sounds available and the possibility to share the content with other social media platforms, could also lead to a high popularity of the app. The short videos are favorable for the short attention span of social media users and not often being interrupted by any comments or advertisements makes watching TikTok videos fun.
In the light of incremental environmental degradation, social awareness and resource depletion along with high and volatile resource prices, food packaging manufacturers in Germany increasingly perceive pressure towards the implementation of circular business models. However, there does not exist any data neither about the current deployment of circular business models nor about the active efforts dedicated by manufacturers in the German food packaging industry while in many cases there is lacking expertise of how to implement circular business models. This thesis is going to close this gap by conducting a systematic observation of 41 food packaging manufacturers’ product portfolio and company policy in order to identify the current state of deployment and active efforts dedicated to the implementation. Moreover, the most applicable measures will be analysed in order to capture the level of circularity in the focal industry, while providing a step-by-step guidance of how to implement circular business models. There was found that the German food packaging industry is characterised by an open-loop approach since manufacturers focus on circular inputs but neglect the reuse and recycling of packaging materials. Besides, there could be identified six highly applicable metrics, which measure a range of different fundamental aspects of the circular economy. Finally, there was found that the process of implementing circular business models can be structured into four phases, whereas a set of key enablers permits food packaging manufacturers to overcome certain barriers and facilitates the implementation of circular business models. The conclusion was drawn that food packaging manufacturers in Germany still show noticeable potential for enhancement in order to increase circularity, especially by launching circular product designs, the reuse of certain types of food packaging and implementing a more holistic approach of circular business models.
Frugality has become a prerequisite for success in a low-resource environment, a reality exacerbated by the COVID-19 pandemic and the war in Ukraine. When it comes to consumer needs, the priorities affordability and functionality are increasingly coming into focus. This study examines how frugal products are performing in developed markets, whether they meet consumer needs, and ultimately if there is a demand for these products.
The aim of this paper is to assess the status of Frugal Innovation (FI) in developed markets, using Germany as an example, and thus consumer behavior, in order to better evaluate the current status and related potentials based on this. The link between FI and environmental and social sustainability can be traced back to and limited to the minimal use of resources. Against the backdrop of the current economic and political situation, these factors represent one of the most significant competitive advantages of today.
This multi-method experiment helps to understand the consumer behavior towards frugal products as well as the opinions and attitude towards it. As a result, it can be said that there is interest in innovation in general as well as FI. The respective buying decisions were balanced, what means that frugal products do not necessarily outperform non-frugal ones, but they are in strong competition. It can be concluded that there will be an increasing demand for frugal products in developed markets such as Germany, especially for certain product categories.
We, a group of students from the "International Business Administration (IBW)" course at the Faculty of Business and Economics, have carried out a project as part of the subject "Managing Business Processes" that is intended to strengthen HFU's international reputation. This digital cookbook is intended to provide our guest students from partner universities with the opportunity to root the culture they have brought with them. On the other hand, we as hosts would like to convey the local culture to our guest students. By sharing diverse, broad and varied cuisines, we as a community could fulfill our motto of students for students. Not only does the HFU CookBook focus on the culinary arts, but it was also possible to facilitate personal student exchanges through an individual fact sheet. Due to the Corona situation, HFU could not live up to its usual standard for international exchange. Therefore it was important for us to enable the students a personal exchange, based on cultural facts, personal experiences and certain background information.
We hope that all readers of this book will enjoy cooking the recipes and learning about the different cultures.
Bon appétit!
This thesis aims to provide a comprehensive and systematic analysis about the growing popularity of Korean pop music (K-pop) worldwide in recent years. On one hand, the international expansion of K-pop can be understood as a result of the strategic planning and business execution that are created and carried out by the entertainment agencies. On the other hand, external circumstances such as the rise of social media also create a wide array of opportunities for K-pop to broaden its global appeal. The research explores the ways how the interplay between external circumstances and organizational strategies has jointly contributed to the global circulation of K-pop. The research starts with providing a general descriptive overview of K-pop. Following that, quantitative methods are applied to measure and assess the international recognition and global spread of K-pop. Next, a systematic approach is used to identify and analyze factors and forces that have important influences and implications on K-pop’s globalization. The analysis is carried out based on three levels of business environment which are macro, operating, and internal level. PEST analysis is applied to identify critical macro-environmental factors including political, economic, socio-cultural, and technological. On the industrial level, major forces that shape the music industry in which K-pop’s business operates are evaluated based on the framework of Porter’s Five Forces. External environmental analysis is followed by the review of the global strategies of major Korean entertainment companies in achieving their organizational objective of turning K-pop into a successful global business. We identify all the key value-creating activities ranging from talent acquisition to customer relationship management in the value chain of K-pop’s industry, and analyze how each of these activities have contributed to K-pop’s success in the global market. In conclusion, the recent success of K-pop on the global stage can be understood as the rewards for the capability of its internal strategy to anticipate and capitalize new opportunities in external environment.
Introduction: Since the first revolution of robotic-assisted surgery officially happened in 2000, the healthcare service worldwide has transformed into a new era due to its superior technological advancements, particularly in laparoscopic surgery. Da Vinci which is seen as a master-slave system and Kymerax which is categorized as a hand-held device are commonly used in robotic-assisted laparoscopic surgery. Whilst a conventional or open method requires a large incision to perform a surgery, laparoscopy - a minimally invasive surgery (MIS) is an advantageous surgical method which reduces an abdominal incision to a minimum, and effectively exploited with robots.
Methods: Based on available articles with the object of robotic surgical surgery, two SWOT analysis for Da Vinci and Kymerax were formulated to understand strengths, weaknesses, opportunities and threats of each system in comparison with the traditional laparoscopic surgery. From that, the future outlook is anticipated based on the scientific background.
Results: Alongside technological advantages of Da Vinci mainly known as 6-degree of freedom, dexterity enhancement, stereovision, tremor filtering and especially minimal invasive surgery, it still has disadvantages that are not neglectable such as huge investment and lack of haptic feedback. Although the malfunction rate of Da Vinci is not significantly high, surgeons should be aware of it to fix or alter instruments in time. Kymerax is not as advanced as Da Vinci but it can fill in the gap of the Da Vinci which includes thelarge investment and bulky instruments. The Kymerax is the low-cost hand-held device allowing multiple degrees of freedom. It is an optimal combination between traditional performance and robotic performance allowing surgeons to manipulate in their hands and ensure haptic feedback.
Conclusions: Both Da Vinci and Kymerax systems offer superior benefits for medical service due to the ongoing technological growth. The cost-effectiveness of Da Vinci system is currently a problematic issue when medical institutions consider to install them. The surgical instruments market, however, has become highly competitive which is likely leading to the decline of the costly investments. In the digital world nowadays, it will be a promising future for more integrated medical inventions.
This research identifies positive and negative influence factors by examining the effectiveness of digital video advertising. The objective is to discover ways of leveraging
these factors successfully through an extensive literature review. As this ad format has developed into a staple in most brands' media strategy, it is valuable to drive
understanding of effective implementation forward. Three brands that utilize digital video advertising are selected for an analysis of their recently published ads. This analysis is supported by a suggested model that was developed based on advertising literature to assess ad effectiveness. Results show that the perceived intrusiveness of an ad and the consequential ad avoidance behaviours in consumers represent a hindrance to ad effectiveness. In contrast, elements used in an advertisement that increase its value facilitated ad effectiveness. Credibility, entertainment and informativeness are ad value contributors and impact ad recall, the gateway to positive marketing outcomes such as purchasing decisions. The circumstances under which consumers are exposed to digital video advertisements play a role in if the ad message can effectively be conveyed.
While negative influence factors have their detriment, they can still be counteracted and leveraged. Advertisers and ad-supported video streaming sites like YouTube can find

Global warming provokes our climate and the world how we know it today to change severely. The production of food together with its consumption is responsible for 19-29% of world’s greenhouse gas emissions caused by human activities and further rises are
expected. As a response to this phenomenon, the assessment of a product’s carbon footprint has awaken huge interest with the purpose of controlling food’s environmental impact during its life-cycle. In order to involve individuals in the target of reducing harmful emissions, besides governmental and business efforts, CO2 labels have been developed to communicate a product’s carbon footprint and enabling consumers to make more climate-friendly purchase decisions. However, it has been shown that a successful
implementation of CO2 labels on grocery products still confronts barriers from the consumer side.
For a better understanding of the meaning of mentioned labels, this thesis deepens the theoretical backgrounds of greenhouse gas emissions and the carbon footprint related to the food industry. In a second step, the acceptance and effectiveness of carbon labels on
groceries will be analysed critically by using contextual literature reviews and a case study on German purchase behaviour.
Growing environmental awareness, especially among young generations, is reflected in the willingness to accept price premiums for sustainable and recyclable products. In recent years, marketers have focused on reinforcing consumers’ attention and interest in green goods by increasing the effectiveness of various sustainability information on product packaging.
In this thesis, an analysis of variance (ANOVA) investigated the effect of visual and verbal recycling claims on product packaging upon the willingness to pay (WTP). Although findings showed no changes in WTP related to a visual claim, the presence of a verbal claim positively impacted the WTP in two of four cases. Further, significant interactions between the two factors were detected. The results suggest that students considered an imagery seal irrelevant during product evaluation, whilst communicating recycling information with a textual message or with a conjunction of both claims showed a tendency to improve price-value perception. However, results for the verbal and interaction effects showed variations across products. Therefore, one may not draw unequivocal assumptions from the findings of this study without research replication on a larger scale.
This thesis investigates the effect choice options in e-commerce applications have on consumers’ decision making. Previous research showed that a large number of options
can affect consumers negatively. However, the conditions for such choice overload are unclear. After reviewing the existing research, the amount of information (entropy)
contained in a choice set and individual differences were determined as possible influencing factors in an online environment. In a choice experiment, choice sets with
varying information loads and an assessment of the Big Five personality traits were used to test the impact of the two identified factors on choice avoidance behavior. Results from chi-square-tests and a logistic regression model suggest choice overload but without entropy having an effect. A logistic regression model revealed that extraverted consumers are easier overloaded. A low Neuroticism score was found to be related to less occurrence of a too-much-choice-effect. Consumers with a high Openness score on the other hand choose one of the presented options more often and were therefore less often
overwhelmed by the assortment. An interaction effect between personality and the amount of entropy was not found. These findings extend the research on choice overload and offer valuable input for marketers targeting consumers online.
Due to technical advances, multisensory technologies have gained traction in the research and development of many industries. With the launch of virtual and augmented reality systems, the potential for these technologies increased even further. The senses of vision and hearing have long been integrated into current products, leading to the assumption that olfactory stimuli are likely to be included soon to stimulate the sense of smell.
With this trend, the issue of implementation into current digital products and services arises, as odors currently cannot be captured in one place and released in another on a large scale. Therefore, this thesis deals with the nature of smell from a cognitive psychological and technological viewpoint. We show why it makes sense to stimulate the sense of smell in multisensory experiences and present early and current technical standards. In addition to this, we conducted expert interviews enabling us to provide insights into the digital scent and olfaction industry. Among other aspects, our results suggest that there are fundamental challenges that developers have to overcome and that a successful implementation depends on the business application.
This thesis aims to ascertain whether the concept of job sharing might be a solution for organizations to adapt their company values to meet the changing principles of society. The shift in demands results from the younger generations seeking different values in their free time, which also influences the demands at work. The disbalance between organizational and individual values leads to employee dissatisfaction and increasing turnover rates. The part-time concept of job sharing is on the rise regarding new work opportunities. Therefore, subtopics including flexibility, work-life balance, gender balance, and diversity in the workforce are positively encouraged through job sharing. The data and research in this thesis are obtained from existing literature on the work concept. Most previous research has focused on the influences on individuals and less on multiple levels within a company. The findings of this paper state that job sharing can significantly impact the value shift of a company in many different facets. Nevertheless, the concept also provides a large number of requirements on several levels which need to be adjusted to benefit from the concept.
In 2013 China's President Xi Jinping announced a new project. In his vision, the Belt and Road Initiative (BRI) creates and opens trade routes between China and western countries, mostly the Middle East, Central Asia, Afrika, and Europe, via maritime and land routes. These trade corridors should establish and improve trade relationships often by high investments in the infrastructure.
The motivation behind the initiative is manifold. On the one hand, China wants to become more independent from the Western industrialized countries by building a new economic system. On the other hand, it wants to consolidate and expand its geopolitical influence.
China's state-owned banks have been the largest investors in the Belt and Road Initiative so far, but China has also been able to attract major EU countries such as Germany, France, the UK, and others to jointly establish the Asian Infrastructure Investment Bank (AIIB) and invest in BRI projects through it.
Although German companies are hoping to participate in the Belt and Road because they expect significant economic benefits, the German government is refraining from concluding an agreement with China for the time being. The EU is somewhat skeptical about the initiative, but no sanctions or interventions have been taken from its side so far. Yet, the EU is split, and countries such as Greece or Italy have already signed an agreement with China and thus received financial support for their infrastructure.
This bachelor thesis explains the Belt and Road Initiative in detail, tries to highlight the motives behind it and illustrates the impact the Belt and Road Initiative has on Germany and the EU and which implications this has for the German economy.
Applications for the Internet of Things are becoming increasingly popular. Due to the large amount of available context data, such applications can be used effectively in many domains. By interlinking these data and analyzing them, it is possible to gather a lot of knowledge about a user. Therefore, these applications pose a threat to privacy. In this paper, we illustrate this threat by looking at a real-world application scenario. Current state of the art focuses on privacy mechanisms either for Smart Things or for big data processing systems. However, our studies show that for a comprehensive privacy protection a holistic view on these applications is required. Therefore, we describe how to combine two promising privacy approaches from both categories, namely AVARE and PATRON. Evaluation results confirm the thereby achieved synergy effects.
Pro-environmental attitude is, on many occasions, a weak indicator for pro-environmental behavior. Personal interests interfere with the human desire to follow normative goals during the decision-making process, which may result in the unpleasant state of attitudinal ambivalence. The more balanced two contrary attitudes are, the higher is the chance for external persuasion as it may decrease the internal ambivalent conflict. However, moral informational interventions seem not to cause the desired behavioral change but may instead increase the sense of resignation and guilt. This paper aims to set focus on the attitude-behavior relationship in the concrete example of plastic-packed food and how post-decisional evaluations vary when either individual (hedonic or gain goal) or collective motives (normative goal) are being followed. Measured indications for actual disengagement or attitude adaption are relatively weak but felt ambivalence in the case of immoral decisions could be demonstrated in the form of response times. Practical conclusions that may facilitate pro-environmental behavior are being presented at the end of the work.
