The notion of frugal innovation or how to do more with less becomes increasingly relevant in a world which faces many severe health care challenges. In general, frugal innovations have the potential to provide low-cost, simple, and valuable solutions to these challenges. Therefore, this research aims to shed light on key success factors and patterns of frugal innovations in the Indian health care sector. For this reason, the research analyzes a sample of nine selected frugal innovations. The frugal innovation examples are examined with respect to their innovation characteristics. Further, the examination of success patterns allows to investigate the potential of reversed innovation in developed countries in order to improve global health. To sum up, the research provides profound insights on the subject of frugal innovations and conclusions on the research questions. Finally, an outlook on future developments in the health care sector and future research are given.
How will the future of business schools in Germany look like in 2035? Scenario Planning with INKA 4
(2019)
Business schools have been largely successful in attracting students and producing publications in the last few decades. Nevertheless, this success has raised several concerns. With many variables influencing business schools, it is useful to predict how the future of business schools might look like. Hence, this paper aims to detect current trends in order to forecast and examine the future of German business schools by the year 2035. With the help of the scenario software INKA 4, future scenarios were generated. In order to develop these scenarios, various areas of influence, e.g. Environment, Supply, Demand, Pedagogy, and Technology were identified and conceptualized with regard to current research and literature. The final result consists of four distinct scenarios, which reflect the potential pathway of German business schools in the future.
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.

Parylene-C is used for various biomedical devices because of its high conformity and biocompatibility. However, delamination could occur because of low adhesion between Parylene-C and other materials. For this experiment 4-inch Si-wafers are used. Parylene is deposited by chemical vapour deposition (CVD). Silane A-174 as adhesion promoter is added between Parylene-Parylene layers. The samples are soaked at different duration 1 h, 24 h and 120 h in PBS solution at 37 °C. A peel test is further performed to investigate the adhesion properties of the samples.
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
ways to broadcast ads without significantly impeding the user experience and, in doing so, secure the continued profitability of this promotion format that depends on users
watching ads.
Nonlinearity of Magnetostrictive Torque Sensor under Varying External Magnetic Field Strength
(2021)
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.
Cybersecurity threads are a huge problem for all sizes of businesses. The traditional way of protecting valuable resources in the IT-Industry is a perimeter based security strategy. To ensure proper access rights for resources, firewalls, and other network-based inspection tools were used. The current move to the cloud undermines classic security strategies by blurring borders. The Zero Trust approach does not rely on edges and borders to ensure network security. Instead, all connections have to be verified and authenticated individually. In this thesis, a zero trust security model in a heterogeneous open source environment was verified. The three main observations were:
A zero trust architecture is possible, but the implementation is difficult. Half of the issues discovered must be covered by organisational measures. The tools available to cover technical measures are not developed enough. This is expected to change in the near future, as varoius companies already identified this issue.

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.
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.
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.
