This paper aims to evaluate the European Green Bond market's current state by analyzing the issuer countries, types, and sectors. Moreover, the impact of regulatory developments in the last two years on the market is analyzed. As a basis for discussion, both literature review and qualitative research in the form of a semi-structured interview were conducted. The interviews were held with four market experts to gain insight into the actual market's reaction to the EU Green Bond Standard and the upcoming EU Taxonomy. In detail, the following questions are answered: What is the current state of the European Green Bond Market? How many bonds are currently issued in Europe and in which countries? Which entities are the most active issuers, and to which sectors do they belong? What are the current developments with regards to regulations? How might upcoming regulations affect the market actors? The European green bond market made up 45% of the global market in 2019, dominated by Germany, France, the Netherlands, Sweden, Spain, and Italy. The market is still in its growth phase, with the amount issued nearly doubling each year. With the introduction of an EU Green Bond Standard, detailed standardization and framework is established. It will help issuers to overcome market barriers such as the risk of greenwashing and helps in identifying eligible projects. However, with the alignment of the EU GBS, an entity has to align with the extensive EU Taxonomy as well, which represents entry barriers to else willing corporations. Whether an activity counts as green or not based on thresholds is defined by the classification of economic activities. The thresholds are heavily discussed in the market as either too high and excluding whole sectors from the market or too low and not ambitious enough. The alignment with the EU GBS and thus with the EU Taxonomy is connected to various efforts. Nonetheless, it offers a great chance for the market by emphasizing the need for climate action. Through this, a strong green market can emerge and hopefully impacts the world positively.
Many entrepreneurs are still conducting business today according to the principle "the purpose of business is business". The focus here is primarily placed on the corporation’s profits while human relations within the enterprise are almost completely ignored. Humanity and business are, after all, seen as two mutually exclusive concepts. However, results of studies undertaken by well-known research institutes, such as Gallup, indicate this management style to be inefficient for businesses in the long run as the resulting low emotional bond of employees with their companies generates high costs for organizations.
For this reason, the present paper examines the extent to which humanity and business are really two mutually exclusive ideas and provides an answer to the research question of whether taking a human approach in a business is a crucial factor for its success. In addition, the possible effects resulting through the integration of humanity in business are analyzed.
To provide an answer to the research question, the currently most recent working challenges in organizations as well as their corresponding demands were first worked out. Subsequently, the human being - with a specific focus on human emotions and emotional needs – was closer examined due to its significance in the company. Finally, the possible effects achieved by taking a human approach in a business were presented on the basis of two already human-oriented corporations. All researches were predominantly based on primary sources as well as on the results of a self-conducted qualitative interview.
The results of all investigations clearly suggest that taking a human approach in an organization is a decisive factor for its success. In addition, it was established that human interactions even help enterprises in achieving astonishingly quick and long-lasting financial successes.
It is therefore plain that it is necessary for companies pursuing the goal to be successful in the long-term to break free from the common principle of "the purpose of business is business" and instead be more open to new forms of management, such as "Humanity and Business".
Zur Stabilisierung der Konjunktur im Zuge der Covid-19-Krise hat die Bundesregierung Deutschlands mit der vom 01. Juli bis 31. Dezember 2020 eingeführten temporären Mehrwertsteuersenkung auf ein noch neuartiges konjunkturpolitisches Instrument zurückgegriffen. Dieses ist zentraler Teil eines mit 130 Milliarden dotierten Konjunkturpakets.
Ziel dieser Arbeit ist, die Wirksamkeit zentraler Elemente der Konjunkturpolitik anhand der damit verbundenen Anforderungen zu untersuchen und die Mehrwertsteuersenkung in diesem Kontext auf ihre Eignung zur Konjunkturstimulierung zu überprüfen. Zur empirischen Untersuchung wurden Experteninterviews mit Wirtschaftswissenschaftlern und betroffenen Verbänden durchgeführt. Die ersten richtungsweisenden Erkenntnisse aus den Interviews, Praxisbeispielen und bestehender Theorie zeigen, dass die Mehrwertsteuersenkung zwar zeitnah und temporär umgesetzt werden konnte, jedoch als wenig zielgerichtet und effektiv zu bewerten ist. Der von der Bundesregierung erhoffte Konjunktureffekt ist als gering zu beurteilen und kam Krisengewinnern stärker zu Gute als besonders betroffenen Branchen. Im Kontext der pandemiebedingten Krise wird zudem die grundsätzliche Wirksamkeit nachfrageorientierter Maßnahmen sowie die praktische Handhabung und zeitliche Koordinierung der Mehrwertsteuersenkung kritisch hinterfragt.
In 2013 China's President Xi Jinping announced a new project. In his vision, the Belt and Road Initiative (BRI) creates and opens trade routes between China and western countries, mostly the Middle East, Central Asia, Afrika, and Europe, via maritime and land routes. These trade corridors should establish and improve trade relationships often by high investments in the infrastructure.
The motivation behind the initiative is manifold. On the one hand, China wants to become more independent from the Western industrialized countries by building a new economic system. On the other hand, it wants to consolidate and expand its geopolitical influence.
China's state-owned banks have been the largest investors in the Belt and Road Initiative so far, but China has also been able to attract major EU countries such as Germany, France, the UK, and others to jointly establish the Asian Infrastructure Investment Bank (AIIB) and invest in BRI projects through it.
Although German companies are hoping to participate in the Belt and Road because they expect significant economic benefits, the German government is refraining from concluding an agreement with China for the time being. The EU is somewhat skeptical about the initiative, but no sanctions or interventions have been taken from its side so far. Yet, the EU is split, and countries such as Greece or Italy have already signed an agreement with China and thus received financial support for their infrastructure.
This bachelor thesis explains the Belt and Road Initiative in detail, tries to highlight the motives behind it and illustrates the impact the Belt and Road Initiative has on Germany and the EU and which implications this has for the German economy.
Die Anforderungen an eingebettete Systeme steigen. Immer mehr Anwendungen mit steigender Komplexität sollen darauf ausgeführt werden, ohne dass der Energiebedarf zu stark zunimmt. Nur durch bessere Hardware lässt sich diese Herausforderung allerdings nicht bewältigen. In dieser Arbeit werden verschiedene Ansätze zur Optimierung eingebetteter Systeme betrachtet. Es werden Optimierungen der Software und der Einsatz rekonfigurierbarer Systeme vorgestellt. Außerdem werden Techniken zur Optimierung des Speichersystems erläutert. Dieses hat einen besonders hohen Anteil am Energieverbrauch eines eingebetteten Systems

Empfehlungssysteme sind aus dem modernen Web nicht wegzudenken. Für Unternehmen können mit relevanten Empfehlungen enorme Summen an Geschäftswert generiert werden. Für Benutzer wird dabei ein personalisiertes Erlebnis auf der Plattform geboten. In dieser Arbeit werden zunächst die Herausforderungen an Empfehlungssysteme sowie die unterschiedlichen Arten von Algorithmen umrissen. In einem Proof-of-Concept (PoC)werden zwei verfügbare Lösungen – Amazon Personalize und
LibRec – untersucht und bewertet. Grundlage des PoC ist ein offline Wikipedia-Modell, welches eine ausgewählte Untermenge von Artikeln aus unterschiedlichen Kategorien in einem zusammenhängenden Graphen abbildet. Zur Generierung von Daten für das Empfehlungssystem wird der Graph von simulierten Benutzern zufällig durchlaufen. Jeder Nutzer bekommt dabei pro Sitzung eine Lieblingskategorie. Artikel aus dieser Kategorie werden sehr gut bewertet, im Graph weit entfernte Artikel bekommen in dieser Sitzung schlechtere Bewertungen. Das Empfehlungssystem soll die Zugehörigkeit der Artikel zu den Kategorien reproduzieren, ohne explizite Kenntnis der Kategorien zu haben. Als Bewertungskriterium werden für jeden Artikel die besten fünf Empfehlungen des jeweiligen Empfehlungssystems betrachtet. Als Metrik dient dabei der Prozentsatz, wie viele der Empfehlungen zur selben Kategorie gehören, wie der Artikel, für den die Empfehlungen gegeben werden. Amazon Personalize erreicht mit diesem Test eine Präzision von über 95%, LibRec erreicht dabei bis zu 73%.
Smart Glasses sind Brillen mit einem integrierten Computer, welche dem Träger visuell Informationen in das Sichtfeld einfügen und mithilfe von Eyetracking, Gesten- und Sprachsteuerung bedient werden können. Smart Glasses werden bereits heutzutage in vielen verschiedenen Branchen wie Beispielsweise in der Logistik, Bauwirtschaft und Flugzeugwartung eingesetzt, um verschiedene Problemstellungen der Arbeiter zu vereinfachen beziehungsweise diese komplett zu lösen. In der Bauwirtschaft werden diese Beispielsweise benutzt, um Leitungen hinter Wänden und unter den Böden zu visualisieren, um diese beim Bohren nicht zu treffen. Aufgrund der variablen Einsatzmöglichkeiten gewinnen diese auch im medizinischen Kontext immer mehr an Bedeutung. Dieses Paper zeigt auf, wie aktuelle und zukünftige Smart Glasses Technologien in Zukunft im Chirurgischen Kontext eingesetzt werden können, um den Operationsprozess optimieren zu können.
Compared to relational databases, graph database systems provide a novel way of processing and analyzing highly interconnected data. Due to their unique properties, graph databases embody an interesting area of research in academic circles. For this reason, this work is fundamentally concerned with examining the state of the industry and current challenges. In this regard, we revisit the basic concepts and highlight the tremendous heterogeneity of available systems using the example of differing path semantics. Based on this insight, we explore algorithmic advancements for graph query processing regarding path finding and worst-case optimal joins. Subsequently, we discuss issues regarding performance and support for graph analytics. Finally, we provide an overview of GQL, a joint standardization effort towards unification of property graph databases.
