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.
Climate change is currently one of the biggest challenges both in terms of danger to natural habitats, wildlife, and humanity. To tackle climate change, we need to reduce our carbon emissions in a fast and decisive way. This thesis studies one of the potential solutions to do so: green hydrogen. More specifically, its potential development by 2030 in Spain using INKA 4.0 scenario planning software.
Green hydrogen shows to have a wide range of applications, from transport to heating and industry with great potential to decarbonize many sectors. It does come, however with a number of important hurdles mainly related to cost, scalability and technical difficulties that will need to be addressed for it to be successful. With this, 10 descriptors were created generating three scenarios to be studied. The most consistent of them, a successful development of green hydrogen in Spain by 2030 is characterized by having all of its descriptors in a favoring state while the other two have some or all in a hindering state, making its development not successful within the established timeframe. Concluding that due to the great challenge the development of green hydrogen is, its success needs to have all factors supporting it.
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.
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.
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.
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.
Patient engagement is the most important element in the process of research/development of medicinal products and healthcare management in today’s times. In a country like India which has a huge population and limited state of regulatory affairs it becomes important to walk the extra mile to protect the patient lives and truly serve them. Time and again it is seen that there is no or limited focus on patient centric processes and we still tend to focus on sponsors as the key stakeholder.
The author in this thesis aims to focus on the clinical trial landscape of India and determine if there is a need to improve the clinical trial processes. If yes, then what type of change is the audience looking for.
The author tries to introduce the human element in the process and remind us all that it is the ‘patients’ who are the centre for the drug development process and serving them and alleviating their pain in the true purpose of the process.
The author along with the helping us find a definition of patient centricity in India, also proposes a model that can be used by the Indian pharmaceutical companies to focus on patient centricity at different stages of the drug development cycle within their organisations.d
Financial technology, popularly known as Fintech, has disrupted and revolutionized the financial service sector. Today, institutions such as banks are adapting digital transformation with the help of technological devices. There is no doubt that Fintech has transformed the way we bank. Nevertheless, there has been a growing need of understanding the future of financial institution with a holistic approach. Regulatory and governmental support towards maximizing opportunity, minimizing risk, and integrating financial inclusion is needed to accelerate the economy and attain sustainable development.
The following thesis aims to study financial inclusion and how to achieve it in the Fintech industry. It comprises of four areas of influence; market, social, technology and regulatory while emphasizing on the economic development, social progress, uplifting digital finance and robust regulatory system in the globalized financial market. The research aims to close the gap among the regulatory, economic, technological and social aspects of Fintech and then develop a pathway to attain financial inclusion. In addition, the objective of the research is to provide a comprehensive strategic plan towards a prespecified future in finance. This was achieved with the help of normative scenario planning. The result was calculated using scenario planning software INKA 4. The result consisted of four distinct scenarios supporting the pathway to implement financial inclusion in Fintech sector by the year 2030.
The German banking landscape is currently undergoing a paradigm shift of an unprecedented magnitude. As the financial world is changing, the future of German banks is highly uncertain. A multitude of present-day driving factors will shape the banking world of tomorrow. Therefore, this thesis aims to investigate and analyze the future of the German banking sector until 2030. The concept of scenario planning serves as underlying method for this research. Based on current factors influencing the German banking sector, the present thesis systematically develops coherent future scenarios. The generation of these scenarios is performed with the help of the scenario software INKA 4. This enables to assess a comprehensive picture of the future environment and the interactions between external influencing factors. Based on the most consistent future scenario, implications for the strategies of German banks are derived. As a result, German incumbents can question their strategic orientation and position themselves optimally for the future.
Entrepreneurship research faces a crossroads and a new approach is needed to better understand entrepreneurial behavior. Incorporating neuroscience to comprehend the entrepreneurial mindset seems promising. Nevertheless, the potential of neuroscience for entrepreneurship research is only slowly being realized. Based on an extensive literature review, this thesis examines the emerging role of neuroscience with respect to entrepreneurship. Referring to the model of the entrepreneurial process, this thesis investigates how entrepreneurs discover, exploit, and finally capture opportunities. In this context, explanations regarding trait, expertise, adaptation, and mindset of the entrepreneur are relevant for further examination. Moreover, decision-making in uncertain situations is analyzed. In this context, the dynamic interplay between the reflective and reflexive system is considered. Ultimately, this thesis provides recommendations for organizational innovation to enhance entrepreneurial
activity.
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 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.
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.
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.
Population growth, urbanization and climate change are regarded as the megatrends of today's society. This goes hand in hand with a high consumption of resources and pollution. Indeed, these megatrends are mutually reinforcing. A significant part of this is due to mobility in daily life. Technological change such as digitalization, creates innovative concepts to improve mobility and to deal with these changing circumstances. A comprehensive concept in this respect is mobility as a service. This thesis focuses on the identification of the mobility ecosystem and thus on the various stakeholders. First of all, it deals with the definition of mobility as a service in order to identify the ecosystem in particular in the second step. Mobility is classified and analyzed by working on the basis of secondary literature and a quantitative as well as qualitative methodology in expert interviews. This allows conclusions about the relationships, prerequisites and obstacles within the ecosystem and stakeholders.
The results of the thesis suggest that collaboration within the ecosystem is a prerequisite for the implementation of mobility as a service. Furthermore, that mobility as a service should ensure adaptability, since local infrastructures differ between Germany, USA and China, but also within these countries. This adaption process is iterative. The obstacles are interoperability and the willingness to cooperate. Moreover, the results imply that mobility as a service will assert itself more quickly in urban areas due to factors such as the pressure to act and the availability of mobility services as well as the number of customers.
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.

Es muss Antworten und Lösungen finden, um in einem global vernetzten Marktumfeld die Wettbewerbsfähigkeit der Supply Chain sicherzustellen. Das Konzept der Blockchain und der Smart Contracts versprechen großes Potenzial. Gerade im Bereich der Prozessautomatisierung und der Kostensenkung, durch das Entfallen bisher notwendiger Clearingstellen. Allerdings stellt sich auch immer die Frage nach der Datensicherheit und Schutz vor unbefugter Manipulation. Ziel dieser Arbeit ist es Anwendungsmöglichkeiten und Potenziale einer Blockchain und Smart Contracts im Supply Chain Management zu identifizieren und zu beschreiben
Subject of the thesis at hand is the analysis of symmetric block ciphers with a block length of 32 bit. It is meant to give a comprising overview over the topic of 32 bit block ciphers. The topic is divided in the examination of three questions. It contains a list of state of the art block ciphers with a block length of 32 bit. The block ciphers are being described, focussing on the encryption function. An SPN-based cipher with 32 bit block length is being proposed by rescaling the AES cipher.
The 32 bit block length results in certain security issues. These so called risk factors are analysed and mitigating measures are proposed. The result of the thesis is, that 32 bit block ciphers can be implemented in a secure manner. The use of 32 bit ciphers should be limited to specific use-cases and with a profound risk analysis, to determine the protection class of the data to be encrypted.
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.
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.
Rising globalization and digitization resulted in crises for the fashion industry. High competition and the interconnectedness of the consumers rule the market and put it under pressure. Owing to the growing power consumers possess, the requirements towards the fashion players are increasing. Customer experience is frequently discussed these days by academics as well as practitioners and emphasized as a competitive advantage. Yet, it is difficult to measure and to track its consequences.
Since customer experience is elusive and no industry specific measurement scale is defined, at first this work aims to identify relevant touch points of customer experience in the fashion industry by dint of a focused interview. The further objective of this paper is to enhance the comprehension of the touch points’ effects or rather the relationship of customer experience with brand loyalty. This is approached by a questionnaire based on the preceding qualitative analysis and the resulting model. This model defines the customer experience touch points as the independent variables while brand loyalty is examined as the dependent variable. The conducted linear regression analysis reveals a moderate effect of customer experience on brand loyalty and the touch points concerning the products as most relevant in this relationship. Additionally, the digitization aspect is addressed by the examination of the relationship in the offline and online channels separately. With respect to this, the present study recognizes that the extent of the customer experience’s impact on brand loyalty and the significant touch points vary across channels to a certain degree.
Mobile diagnostics – or mobile health in general – is highly appealing, not only for clinicians, but also for patients. It implies empowerment, in particular of those who are really in need, such as inhabitants of less developed regions within the world who have limited access to healthcare. It also implies simplification: Easy data management – a continuous flow of information. Therefore, development of miniaturized and highly integrated diagnostic systems allowing near patient “instant” diagnostics gain a lot of momentum since more than a decade. However, system integration requires time and a significant amount of investment. In addition, there is strong competition on resources from other emergent technologies, such as next generation sequencing which made the collection of e.g. human genome data less expensive and much faster. A more severe challenge is that mobile diagnostics require a change in healthcare management, e.g. towards integrated practice units. This, in turn, requires implementation of adequate reimbursement, standards of interoperability, training of staff, quality control. In 2010, Germany’s Federal Ministry of Education and Research (BMBF) launched the grant initiative Mobile Diagnostic Systems (MD, 2011─2015) as part of its high-tech strategy. MD aimed at generating knowledge on how microsystem technologies fit into German healthcare environments. On the basis of interviews with multidisciplinary MD actors, this thesis evaluated retrospectively how the publicly funded innovation network managed to overcome pre-defined external barriers of diffusion, including technology, regulatory affairs and market access. Retrospectives reveal internal barriers involving knowledge and technology transfer, negatively influencing generation of innovation. In particular, financing still represents a high hurdle for biotech innovators in Germany: Larger firms look predominately for market-ready or in-market technologies rather than prototypes and venture capitalists are rare or extremely risk-averse. Another important finding was, that actors involved were highly focused on individual work packages. This risks of not seeing the whole environment embedding MD. Consequently, potential opportunities may be missed, e.g. synergies with relatively close (DIALOC) or more distant initiatives (Global Health Delivery Project-based discussion rounds). This could be partly due to the fact that publicly funded networking activities provide less freedom-to-operate because of pre-defined milestones. In addition, further development of actors with respect to role playing (e.g. boundary spanning or innovation selling) is often not included in such “innovation packages”, but can help to maneuver change. Internal barriers need to be addressed first before targeting the major remaining external hurdle: Reimbursement. Although the latter was covered within MD, standardization of technology evaluation is still an unmet need which strongly influences the willingness-to-implement novel mobile diagnostics. Thus, the value added is to be demonstrated to justify adequate reimbursement. Achieving this goal can be successful, when innovation networking finds its path towards a common vision, e.g. towards value-based integrated healthcare. Pathfinding and visioning can be facilitated by process promoter with excellent network management capabilities. In addition, such a promoter could help to further develop engagement, openness and commitment of collaborators. Therefore, transfer of MD activities to established “top” networks or clusters is recommended for securing valuable knowledge generated. In this environment, an important next step – globalization of MD for ensuring future return on investment – could be triggered as well.
Since MD innovation was found to involve both product and service innovation, maneuvering change is particularly challenging for small and medium sized enterprises. These could benefit from engagement in innovation networking. Findings of this case study can help all direct and indirect actors in the field of MD innovation or in other high complex environments to reconsider pathfinding as well as role playing in networking.
Open Educational Resources (OER) in der Hochschullehre - Anwendungsfall Informationssicherheit
(2016)
Das Ziel dieser Arbeit ist es, die Chancen von Open Educational Resources (OER) im Bereich Informationssicherheit festzustellen und zu fördern. Dabei liegt der Hauptfokus auf Bildungsmaterialien für die Hochschullehre. Um dieses Ziel zu erreichen, wird eine analytische Bestandsaufnahme der aktuellen Quellenlage von Materialien der Informationssicherheit durchgeführt. Die Ergebnisse werden in einer Datenbank festgehalten und theoretisch ausgewertet. Dies zeigt, dass aktuell nur wenige OER im Bereich Informationssicherheit verfügbar sind. Es stehen jedoch vielseitige Ausgangsmaterialien zur Verfügung. Um diese verarbeiten zu können, wird ein Handbuch für OER-Ersteller erarbeitet. Dieses bietet didaktische und lizenzrechtliche Hinweise für die OER-Erstellung. Als Beispiel zur Umsetzung dient das erstellte OER "Risikomanagement in der Informationssicherheit - Risikoidentifikation". Abschließend evaluiert diese Arbeit in theoretischer Form eine Möglichkeit, studentische Arbeiten unter einer freien Lizenz zu veröffentlichen.
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.
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.
