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.
In the contemporary business landscape characterized by global economic uncertainty and rapid technological advancements, companies face increasing complexity in meeting their innovation targets. To address this challenge, established firms are engaging in collaborative partnerships with external entities, particularly startups, to leverage their knowledge and capabilities to gain a competitive advantage. Despite the growing popularity of corporate-startup collaboration (CSC), there remains a noticeable gap in the literature regarding the analysis of the dynamics and key success factors that are relevant to enhancing the collaborative process between these asymmetric entities. This study aims to fill this research space by investigating the dynamics, motives, objectives, and challenges of CSC, with a specific focus on identifying the success factors crucial for achieving favorable outcomes. Drawing upon insights from eight expert managers using a mixed-method approach, the study highlights the significance of addressing internal barriers and prioritizing key success factors to ensure successful outcomes in CSC. The research methodology involves a literature review, a pre-stage questionnaire, and semi-structured interviews to gather comprehensive data. The researchers have synthesized the findings to enhance an existing Co-Canvas model in a way that it is specifically tailored for CSC, thereby offering managers a practical framework to effectively navigate the complexities of CSC. The findings of this research hold implications for scholars, corporate leaders, and entrepreneurs, enabling them to evaluate past collaboration initiatives, identify potential sources of errors, and devise strategies to enhance their collaboration performance. By shedding light on the dynamics and success factors of CSC, this study contributes to the existing body of knowledge and offers valuable insights for strategically enhancing collaboration performance. However, the study refrains from making broad generalizations of the model due to the small sample size of experts.
In the Job Satisfaction- Performance literature largely, job satisfaction is portrayed and
discussed positively as a performance driver for organizations that embark on the journey
of progress. This research asks whether job satisfaction inevitably leads to negative
implementation outcomes and how. This research focuses on factors other than job
satisfaction that can be used to drive better performance of employees and how
satisfaction could also lead to negative outcomes. In an attempt to answer this question,
the research undertakes three key tasks. First, it contextualizes how job satisfaction has
minor affects on performance. Second, it outlines the factors that can increase
performance. Third, it discusses crisply the adverse affects on job satisfaction through
empirical evidence to provide focus and 'evidential grounding' for the research.
Essentially, the research contends that for institutions that are unable to manage and lead
productivity from employees, this research serves a powerful purpose ensuring the multi-dimensional approach to view employee performance and modelled to take account of
the people on whom it may impact as well as the overall value it may deliver.
This thesis examines causes and effects of El Salvador’s transition to official dollarization conducted in 2001. The document analyzes preliminary and final impacts in the real, financial, fiscal, and external sectors of the country, and it also provides an economic and social perspective on how these effects have caused little effect on Salvadoran society. Several authors remark official dollarization might have positive effects on countries with macroeconomic disorders such as high inflation rates and drastic exchange rate variations. After more than 20 years of adoption of the U.S. dollar, official dollarization does not appear to have affected positively life of Salvadoran citizens but rather has prevented governments from using monetary policy to apply irresponsible economic policies and has also helped to prevent high inflation rates. To take advantage of the benefits official dollarization can offer, it is highly recommendable for El Salvador to implement transformative social and economic investments and policies that boost human development and economic competitiveness.
The covid-19 pandemic has significantly impacted economies all over the world, posing as a difficulty for companies all across the globe. The Micro, Small, and Medium Enterprises (MSMEs) in India were one of the most affected. These Enterprises make a substantial contribution to India's economic output.
Despite their significance, these enterprises had faced immense challenges during the pandemic, such as disrupted supply chains, financial needs, loss of customer interest, and administrative problems as well.
This paper, has the intention of studying the aftermath of the COVID-19 pandemic on the MSMEs of India and is focusing on the Volatility, Uncertainty, Complexities, and Ambiguity (VUCA) challenged encountered by them, the strategies that these businesses put into place to keep the organizations afloat, is also studied.
This paper includes a study spanning various fields, exploring the adaptive mechanisms, and strategies incorporated by MSMEs to manage and navigate through the turbulent business environment, sustaining operations and managing risks.
Furthermore, the thesis throws some light on the role of digital transformation in MSME resilience during the crisis, noting its effectiveness and potential barriers. The study aims to give insights and suggestions to better prepare MSMEs versatility against future disruptions, while also looking at government aid or help during the pandemic.
At last, this thesis adds to the understanding of challenges faced by MSMEs during the Covid-19 pandemic, while trying to offer valuable insights for the future.
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.
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.
Traditional networking severely limits the dynamic requirements of newly emerging
use cases like the Internet of Things. For this reason, this thesis is fundamentally
concerned with the proposal of a software-defined networking approach for industrial
IoT networks. We revisit the core concepts, examine related work and subsequently
present an SDN-focused edge architecture for the KOSMoS research project. In this regard, we aim to improve network flexibility, scalability, maintainability and security.
Finally, the developed concept is implemented as an emulated proof of concept in order to assess its feasibility. For our prototype, we present an intent-driven approach that automatically compiles and deploys network configuration policies based on business goals submitted as description templates.
Abstract
In today's business world, it is evident how, thanks to digital transformation, new business models have emerged, especially in the retail industry. Changes in customer preferences have been one of the main reasons why the vast majority of companies within the retail industry have accelerated their digital transformation processes. Evidence has also been found that this change in consumer thinking is related to one of the side effects left by the Covid-19 pandemic, where digital channels gained more strength due to the limitations of physical contact between product providers and their customers. Therefore, changes in consumer thinking and the use of new digital platforms have brought new challenges for companies transforming their businesses from offline to online. The biggest challenges for those companies are not only related to implementing new business models such as online sales or so-called E-commerce platforms but also attributed to the creation of unique and invaluable experiences for the customer, allowing the companies to retain their consumers and create loyalty.
Creating an outstanding customer experience is not an easy task on these platforms since the reach of digital channels is almost infinite, which makes the new entrepreneurs in this industry rethink over and over again the best strategy to approach their customers so that they feel delighted in their customer journey. The present work seeks to provide a solution to the challenge evidenced in the E-commerce platforms, where the main objective is to recognize, through the customer journey, all the critical touchpoints and elements to add value to the shopping experience and to raise levels of customer satisfaction. With the help of tools that measure the levels of customer satisfaction and dissatisfaction, such as the Kano model, and through a recommendation system, the current paper provides com- panies that trade their products online with a detail of what services should be improved in the shopping experience to be highly attractive. In addition, a guide is provided where its application in each company will show in a quantitative way what the customer satis- faction levels are like. This work, through exhaustive research in academia, concludes that the factors that most stimulate customer satisfaction are those related to e-services quality and highlights the importance of “Personalized information”, “Online sales agent”, and “Website reviews and rating” services to add value to customers in one of the most competitive markets, such as E-commerce.
This thesis has the purpose to investigate the oil price as the global economic factor but also to examine its implications on the worldwide economy. Thereby the determinants of the oil price are investigated by tackling the oil price itself from three different perspectives – the supply and demand framework, the prevailing world oil market structure as well as from the perspective of already statistically proven oil price determinants. In addition, the arising macroeconomic implications of oil price fluctuations on oil-importing and oil-exporting countries are examined. The investigation based on a thought experiment demonstrates the supply and demand framework to be unable to fully explain all past price changes. The examination on the prevailing market structure identifies the world oil market to be best described as a supply, pure, closed, partial and collusive form of an oligopoly. Analyzing the competitive behavior of the world oil market on three levels identifies non-OPEC producers’ competition to behave in a Cournot manner whereas among OPEC producers Saudi Arabia is identified to be a Stackelberg-follower with certain conditions while at the same time permanently bearing the ambition to become the Stackelberg-leader. The identification on the best describing oligopoly model for the overall industry is inconclusive. Investigating OPEC’s cartel hypothesis does not fully exclude its collusive behavior but denies the OPEC to be described as a prime example of a cartel. The examination of already existing econometric analyses identified a total of 13 determinants to play a key role in the oil price definition process. Investigating the arising macroeconomic implications of oil price fluctuations show oil price changes to be of great importance for the overall economic performance and is best described as a form of a positive of negative vicious circle in which the interconnected second or even third round effects intensify the implications on the macroeconomic activity.
The pivotal role of the service industry in the economy is increasing over the last decades, as shown by the significant contribution to the GDP made by travel and tourism. Among the varied range of travel companies, this paper focuses on travel agencies. The objective of the thesis is to find out the key drivers, which lead to the success of European travel agencies and to point out the factors that make them unable to compete and develop sustainably. This paper uses the PESTEL model, Porter’s Five Forces model analysis, flywheel concept and spontaneously conducted interviews with travel and tourism industry experts. A case study approach is adopted. There is also the analysis of the financial statements, business model and strategies of the top 15 world-leading travel agencies to find out the market structures and competitors’ behaviors. From the collected data and examination, three primary factors that lead to the sustainable development of travel agencies and four main factors that decreed the failure were identified. Besides, the research also finds out the answer for the three research questions: technology is the disruptive forces in the travel agency industry, there will be no monopoly in this industry at least in the next medium-term, and the adaptation of a new business model is possible. Finally, the study proposed a sustainable development model for a European travel agency as well as directions for future relevant research.
After-sales services play a crucial role in companies’ profit. Their importance is expected to increase given the intensifying leveling of product competition and a shift toward a buyer’s market. Ticketing systems are increasingly integrated into these services because of their ability to bundle multiple support channels, enhance the support’s knowledge base, and cut costs.
This thesis aims to create a comparative overview of ticketing systems, which evaluates eight selected market alternatives and one tentative in-house solution according to their compliance with the requirements of the focus company. This comparison is made by exploring the literature concerning build-or-buy, software evaluation and selection, and analyzing several guided interviews.
The results seek to aid the company in deciding on a ticketing system that meets its requirements, as well as to act as a blueprint for other SMEs. The findings include two recommended alternatives in conjunction with further strategic and decision-making considerations. The study ends with an outlook for academia and businesses.
This research examines the impact of social media on consumer behavior, focusing on how consumer behavior and habits change after the use of social media by German and Chinese young consumers. A comparison of the differences between the two groups is also conducted. The study was conducted based on theoretical background and terminology, followed by six hypotheses. Then this research determined the scope, target population, and sample size before using focus groups and online questionnaires as survey methods. While analyzing the questionnaire data, the research tested the hypotheses and demonstrated the effects between the variables. The results indicated partial agreement with existing studies. Browsing time positively correlates with the purchase journey. The duration of online discounts negatively correlates with transaction speed. Young consumers' demand increases with the amount of time they spend browsing product advertisements. However, some findings ran counter to previous investigations. The impact of SMM on young consumers has no adverse effect on the time spent browsing products. Moreover, only in some cases, young consumers' purchase intentions are positively correlated with demand.

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.
Through an extensive review of the literature, a research gap was identified concerning the knowledge around diversity and its impact on personality types and their influence on group performance. Previous literature revealed that diversity is a popular determinant for group composition, since it encompasses many different meanings and interpretations. Researchers would rather focus on easily measurable elements such as age or gender, but few studies have been conducted on deep-level diversity, such as personality traits or values. The aim of this study is to answer the research questions proposed concerning the effectiveness of homogeneous versus heterogeneous groups as well as the impact communication has on their performance. Through an analysis of previous studies and literature the research questions and hypotheses were formulated, and a methodology designed to answer them. The methodology used in this research was a variation of the Marshmallow Challenge. The groups were faced with two challenges. The first one was to build a 50cm-tall structure as quickly as possible, with a limited amount of material, including raw spaghetti, tape, rope and a marshmallow to test the stability of the structure. The second challenge was presented about one week later and involved the same materials, but the participants had to reach 70cm. Four teams of three were chosen. The personality tests had four possible outcomes: red, green, yellow, or blue. Each colour had specific characteristics and adjectives associated with it. The data collected revealed that the heterogeneous groups performed better overall. A slightly significant correlation was found between how well the teams performed and the words spoken per minute for the first experiment, but not for the second. The biggest limitation that hindered this study was the time pressure and limited sample size.
Nowadays, big sport events such as Olympic Games are not only an exciting carnival for sports enthusiasts, but also a good opportunity for the host country/city to accelerate its economic development. After more than 40 years of development, Computable General Equilibrium has been proved to be a very powerful tool to analyze the impact of big sports events on host country/city. In this paper, 2008 Beijing Olympic Games will be used as the target case to study the impact on the economy. A Supply model and a demand model will be established according to CGE theory to describe the case. This paper is not focused on the detail but the whole picture of Beijing’s economy by analyzing the industrial structure changes under the influences of hosting the Olympic. Beijing’s industrial structure development will also be analyzed in this paper.
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.
The aim of this research is to investigate the unique factors that affect the
adoption of green supply chain management (GSCM) practices in Greek
companies, with a specific focus on how they align with the overall business
strategy and performance. To achieve this objective, a "bottom-up" approach
is utilized, which involves conducting case studies to assess the status of
GSCM implementation in Greece. Additionally, the research seeks to identify
the key barriers that must be overcome for successful integration of GSCM in
Greek businesses.
A primary purpose of the study is to advance the field of Green Supply Chain
Management (GSCM) research by providing new and valuable insights on
the implementation of GSCM in a context that has received relatively minor
or even no attention in previous studies. The findings of this study have
practical implications for businesses operating in Greece and beyond, as
they offer recommendations, solutions and strategies for companies seeking
to implement GSCM practices. Eventually, this research aims to contribute to
the overall development and understanding of GSCM, as well as to promote
sustainable business practices in the region.
