Bei dem deutsch-französischen Kulturkanal ARTE ist die Corporate Social Responsibility (CSR, dt. gesellschaftliche Verantwortung von Unternehmen) ein wichtiger Aspekt ihrer Unternehmensstrategie. Soziale und ökologische Belange sollen in den Unternehmensstrukturen und -tätigkeiten sowie in der Herstellung ihres Programms verbessert werden. Diese CSR-Strategie verfolgt ARTE in einem inkrementellen Prozess, welcher in dieser Arbeit einem organisatorischen Wandel 1. Ordnung (evolutionär, gradual change) zugeordnet wird. Von den Maßnahmen und Veränderungen, welche in der CSR bei ARTE verfolgt werden, sind auch die ARTE-Mitarbeitenden betroffen. Ein organisatorischer Wandel bedeutet nicht nur eine Veränderung auf der Sachebene, er wirkt sich auch auf die psychologische Ebene der betroffenen Mitarbeitenden aus und verlangt Veränderungen in ihren Gewohnheiten. Daher setzen Unternehmen zunehmend auf die Veränderungsbegleitung (Change Management), welche darauf abzielt, eine Veränderung aktiv zu steuern und zu beeinflussen. Eine spezifische Form des Change Managements, die Organisationsentwicklung, hat zum Ziel, bei der Veränderung die Betroffenen zu Beteiligten zu machen. Ein zentraler Aspekt der Organisationsentwicklung bildet daher die Mitarbeitendenbeteiligung (oder Partizipation).
Die vorliegende Arbeit beschäftigt sich mit der Frage, wie die Mitarbeitendenbeteiligung im CSR-Wandel von ARTE erfolgreich eingesetzt werden kann. Im Rahmen eines Praktikums im CSR-Bereich bei ARTE, konnte der Autor durch Beobachtungen, Mitarbeit und Dokumentenanalysen diesen Fragen nachgehen und die Ergebnisse durch fünf qualitative Expert:inneninterviews mit Personen aus dem Top-Management, dem CSR-Bereich und der Herstellungsleitung bei ARTE ergänzen und bekräftigen. Es zeigt sich, dass verschiedene Voraussetzungen erfüllt werden müssen, um eine Partizipation zielführend einsetzen zu können. Zudem kann die Mitarbeitendenbeteiligung in Form von Lösungserarbeitung und/oder in Form der Kommunikation eingesetzt werden. Die Mitarbeitendenbeteiligung wurde bei ARTE im CSR-Bereich bereits punktuell angewendet und es gibt Bestrebungen, künftig in der CSR noch stärker einen partizipativen Ansatz zu verfolgen. Für künftige Anwendungen der Mitarbeitendenbeteiligung im CSR-Wandel bei ARTE werden eine Reihe an Empfehlungen aufgestellt.
Videokonferenzen, überregionale Teamarbeit und ständig mögliche Kommunikation: Durch den in den letzten Jahrzehnten vorangetriebenen technischen Fortschritt sind die Möglichkeiten, global vernetzt zu arbeiten immer weiter gestiegen. Auch die Digitalisierung von Organisationen und die globale Wirtschaft erfordern durch den damit einhergehenden Wandel an Wettbewerb eine verstärkte und sogar notwendige Auseinandersetzung mit virtuellen Unternehmens- und Arbeitsstrukturen. So ergibt sich die Notwendigkeit, virtuelle Teambildung und die damit verbundenen Strukturen zu beleuchten. Ziel dieser Arbeit ist es, ein Modell zur virtuellen Teamentwicklung zu erarbeiten, das als Planungsrahmen für digitale Führungskräfte dienen soll.
Decarbonisation Strategies in Energy Systems Modelling: Biochar as a Carbon Capture Technology
(2022)
The energy system is changing since some years in order to achieve the climate goals from the Paris Agreement which wants to prevent an increase of the global temperature above 2 °C. Decarbonisation of the energy system has become for governments a big challenge and different strategies are being stablished. Germany has set greenhouse gas reduction limits for different years and keeps track of the improvement made yearly. The expansion of renewable energy systems (RES) together with decarbonisation technologies are a key factor to accomplish this objective.
This research is done to analyse the effect of introducing biochar, a decarbonisation technology, and study how it will affect the energy system. Pyrolysis is the process from which biochar is obtained and it is modelled in an open-source energy system model. A sensibility analysis is made in order to assess the effect of changing the biomass potential and the costs for pyrolysis.
The role of pyrolysis is analysed in the form of different future scenarios to evaluate the impact. The CO2 emission limits from the years 2030 and 2045 are considered to create the scenarios, as well as the integration of flexibility technologies. Four scenarios in total are assessed and the result from the sensibility analysis considering pyrolysis are always compared to the reference scenario, where pyrolysis is not considered.
Results show that pyrolysis has a bigger impact in the energy system when the CO2 limit is low. Biochar can be used to compensate the emissions from other conventional power plant and achieve an energy transition with lower costs. Furthermore, it was also found that pyrolysis can also reduce the need of flexibility. This study also shows that the biomass potential and the pyrolysis costs can affect a lot the behaviour of pyrolysis in the energy system.
Global energy demand is still on an increase during the last decade, with a lot of impact on the climate change due to the intensive use of conventional fossil-based fuels power plants to cover this demand. Most recently, leaders of the globe met in 2015 to come out with the Paris Agreement, stating that the countries will start to take a more responsible and effective behaviour toward the global warming and climate change issues. Many studies have discussed how the future energy system will look like with respecting the countries’ targets and limits of greenhouse gases and their CO2 emissions. However, these studies rarely discussed the industry sector in detail even though it is one of the major role players in the energy sector. Moreover, many studies have simulated and modelled the energy system with huge jumps of intervals in terms of years and environmental goals. In the first part of this study, a model will be developed for the German electrical grid with high spatial and temporal resolutions and different scenarios of it will be analysed meticulously on shorter periods (annual optimization), with different flexibilities and used technologies and degrees of innovations within each scenario. Moreover, the challenge in this research is to adequately map the diverse and different characteristics of the medium-sized industrial sector. In order to be able to take a first step in assessing the relevance of the industrial sector in Germany for climate protection goals, the industrial sector will be mapped in PyPSA-Eur (an open-source model data set of the European energy system at the level of the transmission network) by detailing the demand for different types of industry and assigning flexibilities to the industrial types. Synthetically generated load profiles of various industrial types are available. Flexibilities in the industrial sector are described by the project partner Fraunhofer IPA in the GaIN project and can be used. Using a scenario analysis, the development of the industrial sector and the use of flexibilities are then to be assessed quantitatively.
Durch die Fortschritte im Bereich der Quantencomputer rückt der Zeitpunkt näher, dass Quantencomputer die bestehenden mathematischen Probleme lösen können, welche in den aktuellen Public-Key-Verschlüsselungsverfahren verwendet werden. Als Reaktion darauf wurde ein Standardisierungsprozess für quantensichere Public-Key-Verschlüsselungsverfahren gestartet. Diese Arbeit analysiert diese und vergleicht sie untereinander, um Stärken und Schwächen der einzelnen Verfahren aufzuzeigen.
One of the most critical areas of research and expansion has been exploiting new technologies in supply chain risk management. One example of this is the use of Digital Twins. The performance of physical systems can be analyzed and simulated using digital twins, virtual versions of these systems that use real-time data, and sophisticated algorithms. Inside the supply chain risk management field, digital twins present a one-of-a-kind opportunity to improve an organization's ability to anticipate, address, and react to the possibility of problems within the supply chain.
The objective of this study is to identify and assess the advantages that accrue to supply chain risk management as a result of Digital Twins' adoption into the system, as well as to identify the challenges associated with achieving those benefits. In the context of supply chain risk management, a thorough literature study is conducted to analyze the essential traits and capabilities of digital twins and how these qualities lead to enhanced risk management methods. This study investigates the essential properties and capacities of digital twins. In addition, the state of digital twin technology and its applications in supply chain risk management are evaluated, and prospective areas for further study and development are highlighted.
The primary purpose of this investigation is to provide a comprehensive and in-depth analysis of the digital twins' role in supply chain risk management through the utilization of digital twins, as well as to highlight the potential benefits and challenges associated with the implementation of digital twins. The research was carried out based on the existing body of written material and the replies of 27 individuals who had previous experience making use of digital twins and took part in an online questionnaire.
The results of this study will be relevant to a diverse group of stakeholders, including specialists in risk management and researchers, amongst others.
Automation research has become one of the most important tools for future thinking organizations. It includes studying the economic and social aspects to determine how accountants were affected by automating the accounting profession. Moreover, this research studied the social aspect of automation, including the accountants' satisfaction and agreement towards the shift from manual-based accounting to automated accounting. Additionally, the purpose of the research was to comprehend the aspects that affect the variance of the satisfaction and agreement levels before and after automation and whether there is a relationship between those satisfaction and agreement levels and the demographic profile of accountants.
A quantitative method was used to answer the research questions. The findings and results were gathered through an online survey. The respondents in the study represent forty-three accountants who are located and working in Germany. The implications and conclusions of the research were observed from the accountants' perspective.
The research results presented that the automation of accounting significantly impacted the accountants' profession. It indicated that accountants are satisfied with automated accounting and agree with its effects and impacts on their profession. Accountants agreed that automated accounting tasks made the accounting process more effective and valuable. The findings also showed that educational level and length of experience in automated accounting are correlated with the satisfaction of accountants towards automated accounting. It presented that the more experience in automation and higher education accountants have, the more satisfied they are with automated accounting. Due to this phenomenon, higher qualifications and more basic IT knowledge are required in comparison with previous times.
Durch immer erschwinglichere Technik wird der Eintritt in die Videobranche zunehmend einfacher. Gleichzeitig gibt es immer mehr Personen, die am Markt aktiv werden und ihre Leistungen für Kunden anbieten. Was braucht das eigene Unternehmen, um im Bereich der Musikvideoproduktion, speziell innerhalb der Metalszene, erfolgreich zu sein, und welche Kanäle müssen genutzt werden, um Kunden innerhalb dieser Szene zu erreichen? Diese Fragen sollen eingangs durch Experteninterviews mit relevanten Personen innerhalb der Szene beantwortet werden. Anschließend liegt der Fokus der Arbeit darauf, mittels der gewonnenen Erkenntnisse, Literatur und eigenen Erfahrungen einen entsprechenden Unternehmensauftritt grafisch und inhaltlich zu konzipieren und umzusetzen. Dabei beginnt der Prozess bei der Namensfindung und führt über Logodesign, Farb- und Schriftwahl bis hin zur Erstellung der konzipierten Kanäle und Materialien, um die visuellen Arbeiten des Unternehmens bestmöglich zu präsentieren. Neben einer Webseite werden Social-Media-Kanäle, Printprodukte und ein Styleguide erstellt. Die gewonnenen Erkenntnisse und Rückschlüsse werden schließlich bei einer Musikvideoproduktion in der Praxis angewendet und anschließend reflektiert.
On a regular basis, we hear of well-known online services that have been abused or compromised as a result of data theft. Because insecure applications jeopardize users' privacy as well as the reputation of corporations and organizations, they must be effectively secured from the outset of the development process. The limited expertise and experience of involved parties, such as web developers, is frequently cited as a cause of risky programs. Consequently, they rarely have a full picture of the security-related decisions that must be made, nor do they understand how these decisions affect implementation accurately.
The selection of tools and procedures that can best assist a certain situation in order to protect an application against vulnerabilities is a critical decision. Regardless of the level of security that results from adhering to security standards, these factors inadvertently result in web applications that are insufficiently secured. JavaScript is a language that is heavily relied on as a mainstream programming language for web applications with several new JavaScript frameworks being released every year.
JavaScript is used on both the server-side in web applications development and the client-side in web browsers as well.
However, JavaScript web programming is based on a programming style in which the application developer can, and frequently must, automatically integrate various bits of code from third parties. This potent combination has resulted in a situation today where security issues are frequently exploited. These vulnerabilities can compromise an entire server if left unchecked. Even though there are numerous ad hoc security solutions for web browsers, client-side attacks are also popular. The issue is significantly worse on the server side because the security technologies available for server-side JavaScript application frameworks are nearly non-existent.
Consequently, this thesis focuses on the server-side aspect of JavaScript; the development and evaluation of robust server-side security technologies for JavaScript web applications. There is a clear need for robust security technologies and security best practices in server-side JavaScript that allow fine-grained security.
However, more than ever, there is this requirement of reducing the associated risks without hindering the web application in its functionality.
This is the problem that will be tackled in this thesis: the development of secure security practices and robust security technologies for JavaScript web applications, specifically, on the server-side, that offer adequate security guarantees without putting too many constraints on their functionality.
As information technology continues to advance at a rapid speed around the world, new difficulties emerge. The growing number of organizational vulnerabilities is among the most important issues. Finding and mitigating vulnerabilities is critical in order to protect an organization’s environment from multiple attack vectors.
The study investigates and comprehends the complete vulnerability management process from the standpoint of the security officer job role, as well as potential improvements. Few strategies are used to achieve efficient mitigation and the de- velopment of a process for tracking and mitigating vulnerabilities. As a result, a qualitative study is conducted in which the objective is to create a proposed vulner- ability and risk management process, as well as to develop a system for analyzing and tracking vulnerabilities and presenting the vulnerabilities in a graphical dash- board format. This thesis’s data was gathered through an organized literature study as well as through the use of various web resources. We explored numerous ap- proaches to analyze the data, such as categorizing the vulnerabilities every 30, 60, and 90 days to see whether the vulnerabilities were reoccurring or new. According to our findings, tracking vulnerabilities can be advantageous for a security officer.
We come to the conclusion that if an organization has a proper vulnerability tracking system and vulnerability management process, it can aid security officers in having a better understanding of and making plans for reducing vulnerabilities. In terms of system patching and vulnerability remediation, it will also assist the security officer in identifying areas of weakness in the process. As a result, the suggested ways provide an alternate approach to managing and tracking vulnerabilities in an effective manner, although there is still a small area that needs additional analysis and research to make it even better.
