The financial markets are currently facing uncertain circumstances, which is increasing their tail risk. A recent study was conducted to measure the tail connectedness between North America, Latin America, Europe, Asia, and Oceania. The study looked at 18 stock market indices using a neural network quantile regression approach from January 4, 2012, to May 5, 2022. The study found that the North American, European, and Latin American stock markets had the highest exposure to tail risk, while Asia and Oceania showed no significant risk compared to the rest of the world indices and were independent. The study also identified the Global Financial Crisis and the COVID-19 pandemic as intense events that yielded high tail risk. The Systematic Fragility Index ranked the pre-COVID period stock market and the Nasdaq during the COVID sample as the most susceptible markets. On the other hand, the Systematic Hazard Index identified the S&P as the chief risk contributor in the system.
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.
There is an increase in concern for the environmental impact such as GHGs emission and hazardous chemicals discharge along with the wastewater, from the product production process. Likewise the concern in the social impact also rises, in which it include the use of forced and child labor, unfair wages and inhumane treatment of worker in the production process of various industry.
Moreover, with the change in business strategies to fast fashion, in which new product collections are launch four times a year. In response, company have change the structure of their supply chain to shorten lead-time, higher inventory turnover, high order fulfilment and lower price for their customer. However, while focusing on these factors, environmental and ethical are being overlooked.
With the pressure from the public, laws mandate by the government, as well as the foreseen market opportunity make many of the large company to start thinking about a way to eliminate environmental and ethical impact from their supply chain. Various techniques and instruments are developed in order to help the company to analyze and abolish these problems.
Two companies are used as an empirical studies, which are H&M and Inditex. Though the analysis the challenges they faced and instruments and technique they used in response to the challenges, one can clearly observe the different approach in handling the challenges of these two companies. Nevertheless, positive improvement in eliminating environmental and social impact from their supply chain can clearly be seen from their effort.
Unfortunately, even in these years of high innovations in society, many countries still have gaps in basic needs such as energy supply. Many people live off-the-grid (OTG) referring to not being connected to the main or national electrical grid since they live scattered or in remote location or simple because it is unaffordable. On the other hand, according to the International Energy Agency (IEA), the use of fossil energy increased in the 8 firsts years of the 2000 decade, and half of the energy use in the last decade was accounted to coal. This type of energy source is proven to be harmful for the environment contributing to global warming. New methods of energy storage have been created mainly in developed countries. For example, the photovoltaic (PV) lamps as the main product of a German company that fulfill needs in sustainable and renewable energy resources. However, developing countries may also need to look for practical solutions and the private sector can help. The financing of renewable alternatives is imperative to increase progress and, in these sense, private sector can help. For instance, increasing systems using solar energy for rural communities and promotion of affordable and efficient PV products such as portable eco-friendly solar lamps that replace the kerosene lamps, fan plus lamps, water filters and icemakers among others are helpful in OTG communities and need to be supply. Entrepreneurs that focus in fulfill this gap in society creates value and make a change in the countries. The importance of increase electronic appliances (energy-efficient) and “smart” applications (home area networks and energy storage devices) is undeniable for progress in developing countries and better energy use all over the world Solar energy provides products that not only help people but also maintains a balance between nature and habitants.
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.
Non-R&D-intensive firms and industries play and continue to play an important role in the German manufacturing industry, as their 41% share of value added in 2007 indicates. Nonetheless, non-R&D-intensive SMEs especially need to ready themselves for a future shaped by a continuously increasing internationalization of competition, rising knowledge intensity and complexity and an impairing job market situation due to demographic changes. Non-R&D-intensive SMEs are therefore more than ever required to boost the effective and efficient exploitation of firm-specific resources and competences in order to generate, secure or enhance competitive advantages. As studies however show, existing strategic competence management concepts are currently implemented rather by large firms. In addition to small firm size, low R&D intensity effects staff setup, innovation behavior, generation and use of knowledge and competitive market behavior which further negatively influence a firm's possibilities and propensity to implement these strategic competence management concepts. In a first step into this field of study, this master thesis aims to identify and analyze specific characteristics facilitating or discouraging an implementation of strategic competence development processes in non-R&D-intensive SMEs in the form of requirements, drivers and barriers. A literature review addressing the particularities of non-R&D-intensive SMEs and the attributes of current strategic competence management concepts discouraging an implementation of strategic competence development builds the foundation for nine guided interviews of explorative nature involving four non-R&D-intensive SMEs conducted to acquire qualitative empirical data to complement the theoretical findings. A total of 22 specific characteristics, i.e. eleven requirements as well as six drivers and five barriers, facilitating or discouraging an implementation of strategic competence development in non-R&D-intensive SMEs were identified after forging the bridge between theoretical and empirical findings.
Before the eruption of the latest financial crisis in 2008, Social Responsible Investments were considered as not relevant within the financial market's spectrum, in fact, late 90`s academic literature argues that Social Responsible Investments worsen portfolio performance, seemingly a well established paradigm for almost thirty years. However, why the perception of financial markets about Social Responsible Investments is changing?
Given the controversy surrounding Social Responsible Investments, the current document has tested the performance of a selection of Social Responsible portfolios for the period (2007-2014). Results showed that performance is not diminished and Social Responsible portfolios do not perform significantly different from the benchmark market. Additionally, theory and results are replicated into an interactive business game that aims to discover Social Investment profiles for users and highlight the importance of Social Responsible Investment in financial markets making the current document a combination of financial theory with the design of practical game fully playable.
Common problems that urbanized areas have to face are an increase in accidents, air and noise pollution, traffic jams, lower road security and reduced available space. The increased amount of carbon emissions (CO2) is creating severe consequences that can be observed in climate change. Smart Mobility can help to put under control and lower the CO2 emissions derived from the transport sector. Thus, the paper investigates the benefits and challenges of Smart Mobility. Then, through a confrontation of two benchmark areas which are successfully adopting Smart Mobility techniques, and the utilization of SWOT and data analysis, it shows that Smart Mobility can effectively lower CO2 emissions from transport. Ultimately, the NEXT-Future Transportation project is proposed as an innovative solution that addresses most of the mobility challenges and incorporates the needs for future transportation.
This research aims to study transactional cost and organizational change management in a pharmaceutical company that had gone through the SSC implementation process through different regions, including Latin America. Eli Lilly SSC in Latin America is located in Mexico and was aimed to centralize standard routines and administrative transactions related to finance and accounting back office services for the entire region. In implementing changes of this magnitude, it is necessary to be prepared to encounter the transaction costs related to this strategic decision and for the internal resistance applied in organizational change process. In this sense, this research aims to study what are the main challenges and transaction costs involving a process of re-structuring the organization to the SSC business model, especially in Latin America. Taking as a base the change resistance elements mentioned by Burns and Scapens (2000) and transaction costs theory basis by Williamson (1981). The SSC, a relatively recent business model and a trend between multinational organizations, was implemented in Lilly across 4 different regions to support over 70 countries in all continents. Latin America the last region to be implemented had a proposed migration schedule within less than one year. The findings show that the main resistance to the existing process is related to lack of competence/information and attachment to control and existing routines. In addition, the transaction costs are closely related to the dimensions of asset specificity and uncertainty. We must consider that the lack of a formal change management strategy, within the LATAM region, was a risky move and had impacted the implementation process and stabilization period results. The chronogram had also to be changed due to unexpected details in the region. Latin America was more complex than expected due to the differences in regulations and culture between countries, also expressed a non-verbal resistance that was probably expressed through the lack of commitment of some personnel. The results of this research raise inputs to the next researchers and bring elements to be considered by organizations when implementing the SSC business model. It is useful to direct actions and strategies to control de change impact and possible transaction costs. Additionally, through the research we filled the purpose to build an overview on shared services model and discuss the main points that should be considered when taking into consideration to re-structure the business with this model, characterized as a centralization of services that are provided from one single point to multiple business units in order to avoid activities duplication, optimizing resources through the integration of technology, people and standardized processes (Deliotte, 2007).
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.
This research is aimed at analyzing social media patterns of consumers in Russia and in Germany, and social media strategy of automakers. The purpose of the paper is to observe social media presence of three major car manufacturing companies and see what the social media preferences of consumers are during purchasing journey. Furthermore, the results include comparison between Russia and Germany as well as social media best practices of automakers. For this, data was collected from a random sample of people in Russia and in Germany through online questionnaire. After that an analysis of secondary data on social media presence of automakers was done. A total of 650 people participated in the online questionnaire. The data was analyzed for each country and compared with each other. The results revealed that there are a lot of similarities in social media usage. However, existing differences are very drastic and needed to be considered by companies when it comes to establishing a social media strategy in a specific country. Furthermore, selected car manufacturing companies have a relatively strong social media presence but are different among each other with some gaps that can be improved.
Cost Optimization is a persistent discipline to adjust expenses and reduce costs while maximizing business value, and it has proven to be one of the most influential strategies to generate profits and stay competitive in the market. In this study, technical and strategic solutions that can lead to manufacturing cost optimization were considered. For this purpose, a test environment was created according to the DFMA methodology using the DFMA Concurrent Costing V4.1 software developed by Boothroyd Dewhurst Inc. and the production expenses of a JED029M3 aluminum bushing product from WABCO Group were analyzed.
Results revealed that these charges can be assigned to five main cost drivers Material, Machine Setup, Process, Scrap and Tools, of which Tooling was the most influential driver at lower volumes, while Material and Process remained two of the considerably substantial drivers across all ranges of volumes produced. Furthermore, among the optimization alternatives, the right choice for machine and raw material shape demonstrated to have a relative effects of less than 5% in reduction of manufacturing cost for 1,000 pieces, while outsourcing to China and transitioning toward economies of scale lowered could impact the total costs by -40% and -70%, respectively.
As waste generation increases, so are initiatives to recover products and recycling. A particular waste that has continuously grown is plastics. Since its introduction, it has provided practical implications to different industries; however, it has also negatively affected the environment by its disposal. The recycling of plastic has offered opportunities to conserve non-renewable fossil fuels, reduce energy consumption, and avoid waste. Many countries seek for a sustainable system to recover plastics such as PET bottles. Mexico’s high soft-drinks consumption had consequently increased the disposal of PET bottles. Mexico has developed a recycling industry of PET bottles by following a Shared Responsibility between government, industry and society. However, a lack of awareness and knowledge among the society about the importance to collect the bottles and to recycle them makes it imperative for the introduction of a system that could create a society that recycles more. Providing a description of the opportunities and challenges for a collection system in Mexico simplifies future chances of comprehending the direction and actions needed for increasing recycling activities in the country.
This thesis analyzes the effects that product label certification of Fairtrade products and the retail format where they are bought by consumers (Supermarkets vs. Discounters) have on the Willingness-to-Pay (WTP) of common grocery store goods. The thesis builds on data obtained from an online-conducted survey where participants had to respond if a determined price point was deemed as cheap or expensive to them and based on the average reaction times of their answers we determined the individual WTP. Two-way ANOVA analysis were performed with this data and some interesting findings were discovered: while a difference can be observed in consumers WTP for goods depending on the retail environment where they are acquired, there is no evidence of multiplicative effect of product labeling and retail format.
Advantest Company ("the company") is the world’s leading manufacturer of automatic test and measurement equipment used in the design and manufacturing of semiconductors. Because of the complexity of technologies and the supply chain of the semiconductor business segment, the company depends on both internal and external suppliers to manage some aspects of the supply chain of its main product, the System on Chip (“SoC”) test system. As a result, it is of ongoing interest to the company to have tools to continually strive for increased quality, reliability, capacity, and speed. Above all, these tools must enhance the relationships with the suppliers, and ensure the profitability and the company's position in the future.
The goal of this thesis is to understand the supply chain procedure at Advantest Company’s current state from the data-driven perspective by using the process mining technique. This technique is an emerging discipline, providing a comprehensive set of tools to provide fact-based insights and support process improvement. This new discipline is built on process model-driven approaches and data mining.
In this thesis, we discuss opportunities for process mining with an approach to analyse the process and how it can help the company enhance the procedure. This approach, which consists of data extraction from both third-party and internal software solutions, provides better visibility and faster disruptive event notification of the supply chain at the company.
Pricing is one of the foundations of any company’s market strategy and the only factor of the marketing mix that deals with revenue generation. The other three viz. product, promotion and place deal with expenditure. Pricing strategies provide varied degrees of flexibility based on organizational capabilities and customer segments. Pricing decisions are fundamental to a firm’s growth and are complex in implementation. Based on the author’s research, value-based pricing provides the best fit for all the important pricing factors like cost structure, profit margin, competition, supply and demand, etc. Despite this, cost-based and competition-based pricing strategies are still being widely used. The IT service industry in India has long focused on the competitive advantages of cheap and abundant manpower but the lack of focus on product development together with the emergence of other low waged countries and the growing nature of technology adaptation in the country have presented significant motivation to these IT firms to invest in research and development aimed at enhancing their product portfolio, which can be best taken advantage of by moving their pricing decisions towards a customer-value centric approach. Basing their prices on the different customer segments and focusing on value generation is the best way forward in the face of increased competition from both domestic and international organizations.
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.
