To control the spread of the virus, countries around the world were forced to implement various strict measures that includes travel bans, lockdowns, and limited social contacts. As per pervious pandemics, this crisis had severe consequences on economy, consumer behavior, purchasing decisions and people's mental and physical wellbeing. Consumers were forced to adapt and find alternatives that would fit the "new norm". This added to the psychological distress people were experi-encing and in turn increased their feeling of risk and uncertainty. Thus, this research con-ducts a semi-structured exploratory in-depth interview (N=16) to profoundly investigate the effect of risk and uncertainty on consumers' purchasing decisions in Germany. Find-ings of this study suggests that consumers with high uncertainty avoidance and high per-ceived risk are more likely to have a changed behavior. Their purchasing decisions are more oriented toward necessities and self-development products. On the other hand, con-sumers with low uncertainity avoidance and risk perception have experiences less change in terms of consumer behavior and purchasing decisions. The results of this research would help companies understand consumers' psychological needs which is often ne-glected in literature to provide the needed products and services. It would also benefit the academic and professional world by knowing what to expect during crisis and if changed behaviors will continue after the pandemic is over.}, language = {en} } @masterthesis{Ponten, type = {Bachelor Thesis}, author = {Ponten, Marvin}, title = {Visualisierung von Kulturg{\"u}tern am Beispiel der r{\"o}mischen Kaiserthermen in Trier als 3D Modell.}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-15889}, school = {Hochschule Rhein-Waal}, pages = {49}, abstract = {This paper is a summary of the "Kaiserthermen Project'' for the "Landesmuseum Trier" and shows in detail how to convert a 3Ds Max 3D model for usage into an open source program like Blender.

The experiment is conducted at temperature points of 60°C, 70°C and 80°C, where at each temperature point cathode stoichiometry of 2 and 5 are set. Within each stoichiometry, the cell is operated at cathode relative humidity of 50\%, 75\% and 100\%. The fuel cell performance is analyzed using two methods, current-voltage measurement, and the electrochemical impedance spectroscopy, where the polarization curves, power output density and high-frequency resistance (HFR) are recorded. A numerical analysis is then conducted on a 3-dimensional straight single channel fuel cell and is fitted with the data measured experimentally. Increasing the temperature has a different degree of improvement on the fuel cell's performance based on its cathode stoichiometry and relative humidity settings. The HFR measurements provide an insight into the voltage loss that is exerted by the fuel cell on each test condition. The numerical analysis shows that the impact of operating conditions does not exhibit any significant differences on the fuel cell model.}, language = {en} } @masterthesis{Fischer, type = {Bachelor Thesis}, author = {Fischer, Luca Cedric}, title = {An Empirical Investigation on the Transparency of Capital Costs in the Annual Report among the DAX40 Companies}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-13679}, school = {Hochschule Rhein-Waal}, pages = {78}, abstract = {This study identifies the transparency levels of the DAX40 companies regarding their disclosure of capital costs. With reference to a theoretical foundation, capital cost theory and its origins are outlined, while the respective financial reporting standards according to IFRS and HGB are discussed. In the matter of preliminary step before examining the annual reports of the mentioned German companies, transparency in financial reporting is critically assessed in an in-depth literature review. The topics of efficiency of transparency, motives for transparency variations and consequences of transparency for companies are included. As a result, five hypotheses were derived that build the basis for the subsequent empirical case study. Thus, H1 expects most of the companies within the DAX to not transparently publish their capital costs within their annual reports. H2 expects that none of the DAX companies are transparent about their calculation scheme and application regarding the beta coefficient. H3 assumes that most companies listed in the DAX are inconsistent with their capital costs used for the Impairment Only Approach compared to the capital costs communicated in the management report. H4 predicts that most DAX companies are not publishing separate WACC's and derivation of capital cost parameters along their business units. Finally, H5 expects the ten new joiners within the DAX to be more transparent and consistent regarding their publication of capital costs and calculation schemes than their 30 peers.

The SPD, B{\"u}ndnis 90/Die Gr{\"u}nen and the FDP now make up the german parliament. Parts of the election campaign are taking place via social media. But how do the individual parties use modern media? Do the parties differ in the way they communicate their messages and, as a result, do they generate votes in diffe-rent ways? I will examine these questions in more detail in this bachelor's thesis, starting with the reunification of germany and including the last federal elections. The social me-dia platform I am investigating for political communication is twitter. I presented the past and current parliamentary election results and differences in eastern and western germany. To do this, I used sentiment analysis to examine tweets extracted from twitter at the federal and local/state political level, for their content and the accom-panying reactions. I created a detailed representation of the different social media appearances of politicians and determined whether appropriate conclusions can be drawn based on my results and data. My analysis shows that at the parliamentary level, Annalena Baerbock of B{\"u}ndnis 90/Die Gr{\"u}nen, followed by Dr. Alice Weidel of the AfD and Christian Lindner of the FDP, have the most likes and retweets. Olaf Scholz, with 826 tweets, is the most active on twitter in 2021. At federal and local/state level, the topics of all parties are often similar. There are differences with regard to the core issues of the respective parties. I have illustrated this in each case. Based on the politicians' use of twitter, I could not draw any concrete conclusions about voter behaviour. For this it would be important to evaluate other media, e.g. facebook.}, language = {de} } @techreport{Guggenberger, type = {Working Paper}, author = {Guggenberger, Lennart}, title = {Die Befristung von Arbeitsverh{\"a}ltnissen in der Rechtsprechung des Bundesarbeitsgerichts}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-15671}, pages = {6}, abstract = {In diesem Arbeitspapier werden die Befristung von Arbeitsverh{\"a}ltnissen und aktuelle F{\"a}lle der Rechtsprechung er{\"o}rtert.}, language = {de} } @masterthesis{Salobir, type = {Bachelor Thesis}, author = {Salobir, Randy}, title = {Dark Patterns in Videospielen - Unterschiede zwischen Casual-, Core- und Hardcore-Gamern}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-14911}, school = {Hochschule Rhein-Waal}, pages = {76}, abstract = {Gaming has become a huge industry. In an attempt to generate more revenue, manipulative design decisions, aimed towards making the consumer act in certain ways or perform certain actions, which are beneficial to the developers of the game, have become a common sight. Those design decisions have become known under the umbrella term "Dark Patterns". While individual Dark Patterns have already been researched on their impact on gamers as a whole, it stands to reason that groups with widely different gaming behaviors would exhibit differences in their exposure and vulnerability towards these patterns. This bachelor's thesis aims to use a quantitative approach in the form of an online survey (n=465), to research this. For that, the survey asked questions about the participants gaming behavior and interactions with a wide array of Dark Patterns. The participants will then be grouped into casual-, core- and hardcore gamers based on their answers about their gaming behavior, after which the groups will then be directly compared in terms of their exposure and vulnerability towards Dark Patterns, in order to find any significant differences.

Both sites were evaluated with respectively three test subjects for every site, to find out which site is more user- friendly. For this purpose The Web Content Accessibility Guidelines (WCAG) were explained. Afterwards ten E-Commerce-Sites that sell Dog Food were analyzed on their conformity to the WCAG, to find the most common WCAG-violations, in order to prevent these in the later implementation of the prototype. This prototype was developed in three stages, the first one was a paper-prototype to concept the structure. The second was modeled through the software „Figma" to specify the styling. At the end the final prototype was implemented in HTML with the „Angular" framework. Thereafter, the prototype was examined through user-tests to check if there were usability-errors or inaccessible elements, that need to be fixed in order to accomplish an accessible prototype. After the result were evaluated and the found accessibility- errors were fixed. The prototype went again through a usability-test execution, to ensure that the prototype is accessible. The result show, that the accessible site is more user-friendly and WCAG compliant than the inaccessible site.
