No full textUntersuchung der Präferenzen der Generationen Z und Y bei der Arbeitgeberwahl unter Betrachtung der Arbeitgeberattraktivität - eine empirische Untersuchung
No full textDas Ziel der vorliegenden Bachelorarbeit ist die Präferenzen der Generation Z und Y gemessen an der Arbeitgeberattraktivität zu analysieren und entsprechend zu vergleichen. Dazu wurden
93 Studierende in einer quantitativen Onlineumfrage befragt. Die Umfrage basiert auf der Employer Attractiveness Scale von Berthon, Ewing & Ha aus dem Jahr 2005 sowie auf der Authentic Living Scale von Wood et al. aus dem Jahre 2008. Ergänzungen wurden in den Bereichen ethischer Diversität, Unternehmenskultur, Glaubwürdigkeit, Authentizität und persönliche Werte vorgenommen. Diese Aspekte sind im Fragebogen von Berthon, Ewing & Ha im Vergleich mit anderen Arbeitsattraktivitätsmodellen, beispielsweise das Treiberfaktorenmodell von Nagel (2011), unterrepräsentiert, haben allerdings laut einer umfassenden Literaturrecherche für die jungen Generationen Z und Y an Wichtigkeit zugenommen. Die Ergebnisse liefern einen umfassenden Vergleich zu allgemeinen Aspekten der Präferenzen beider Generationen an den Arbeitgeber. Die jungen Generationen unterscheiden sich nur leicht voneinander, was aufwändige Anpassungen an HR-Strategien und Praktiken nicht notwendig macht.
Die Bachelorarbeit ist für jegliches Unternehmen interessant, das ihre Zielgruppen (Generation Y & Z) zum Zweck der Rekrutierung besser verstehen möchte. Die Ergebnisse können in Recruiting- und Employer Branding Maßnahmen adaptiert werden

No full textMedien als politisches Mittel: Propaganda und ihre historische Entwicklung
No full textIn der vorliegenden Literaturarbeit wird die Entwicklung von Propaganda anhand des Fortschritts von Massenmedien des 20. Jahrhunderts und der digitalen Wende um 2000 untersucht. Beginnend mit der Beschreibung von Büchern als Medien wird das letzte Jahrhundert chronologisch bis zum Fernsehen behandelt. Dabei werden historische Ereignisse in Verbindung mit der Verwendung von Propaganda gebracht. Mit Beginn des digitalen Zeitalters verlagert sich der Handlungsraum der Propagandamethoden aus der analogen auf die digitale Welt. Auszeichnend sind die Geschwindigkeit und Erreichbarkeit großer Menschengruppen mithilfe des Netzes. Durch die Demokratisierung des Internets in Form des Mitmach-Webs können Nutzende gezielt durch die Verwendung von Algorithmen und von künstlicher Intelligenz gesteuerten Social Bots angeworben werden. Es wird auf die Gefahren von Filterblasen und Echo-Kammern eingegangen, die zu einer Radikalisierung führen können. Vorschläge zur Eindämmung der Instrumentalisierung von sozialen Netzwerken zu Propagandazwecken durch die Verbreitung von Fake News und Verschwörungsnarrativen werden sowohl für Nutzende, Institutionen, der Regierung als auch für Tech-Unternehmen unterbreitet.The present work examines the development of propaganda based on the progression of mass media in the 20th century and the switch to digital media around the year 2000. Beginning with the description of books, the mass media of the last century is described chronologically up to the topic of television. Historical events are associated with the use of propaganda. With the onset of the digital age, the scope of propaganda methods is shifting from the analogue to the digital world. The risks on the internet of these processes are highlighted. Particularly outstanding is the speed and accessibility of large groups of people with the help of networks. By democratizing the internet with the help of the participatory web, users can be targeted using algorithms and artificial intelligence-driven social bots. The dangers of filter bubbles and echo-chambers, which can lead to radicalization, are discussed. Proposals to curb the exploitation of social networks for propaganda purposes through the dissemination of fake news and conspiracy narratives are laid out to users, institutions, governments and tech companies
Unravelling mortality of Perca fluviatilis: Meta-analysis and integration into a physiologically structured population model
No full textPerca fluviatilis is widely distributed food generalist fish across the Europe and Asia (Couture and Pyle, 2015). As a part of the project by Winkelmann et al. (2022), the continuos physiologically structured population model (cPSPM) of P. fluviatilis was established which appeared to have potential points for improvement. In this study, I attempted to modify mortality function of the population model. Hence based on thorough literature research 4 models for mortality estimation mortality as well as the data of life-traits of perch were found. The models include Hoenig-Then (Then et al., 2015), Pauly-Then (Then et al., 2015), Lorenzen (Lorenzen, 2022). and Weibull probability density function as function of weight dependent mortality. The methods were parametrised via arithmetic average of population specific traits and non-parametric least-square method. As a result, the mortality models were compared to each other as well as to the base model. Further on, each mortality model was integrated into cPSPM and stable population was found. At the end only Lorenzen and Weibull models were analysed. As a result of mortality model comparison, it was found that the difference between these models lies mainly in difference of magnitude. Integration of the models into cPSPM showed the potential correlation between the mortality and reproduction. The comparison of simulations results in similarity in population dynamics of our models with experimental data, with main difference in magnitude. Overall results suggest that every model has reason to be applied, and all of them have their own application. In terms of current cPSPM, it would be suggested to consider population dynamics of perch over multiple years period with different mortality method employed for each year to address the issue of variability of population dynamics on yearly basis
The Impact of Leader Behavior on Team Processes
No full textThe modern work environment is subject to constant change with a notable shift from individual to team-based work structures. This transition necessitates an improved un-derstanding of how managerial actions influence the dynamics within these teams, to optimally align them for success. Despite the substantial research about leader effec-tiveness and team effectiveness based on organizational performance indicators, it is rather infrequent that the direct influence of leader behavior on teams is explored. This thesis aims to address this gap by answering how leader behaviors impact team pro-cesses in the context of German medium to large-scale IT-enterprises. Using a quanti-tative cross-sectional methodology, individuals working in team-based structures under direct supervision were surveyed. Analyzing data from 94 respondents via hierarchical linear regression analysis, several significant relationships were identified. In general, leader behavior has a strong positive impact on team processes. Furthermore, task-oriented leaders have the greatest positive influence on action processes, while relation-oriented leaders have the greatest positive influence on interpersonal processes. Change-oriented leaders also significantly influence action processes and interpersonal processes, albeit less strongly than their counterparts. These results provide implications for team management practices, emphasizing the importance of leader behavior for aligning team processes in the direction of success

No full textSurvey of Eutheria for Alternative Caseins Suitable for Recombinant Production
No full textCaseins are the most abundant protein component in mammalian milk, and they are released as calcium-rich micelles. These phosphoproteins originate from four genes responsible for encoding αs1, αs2, β, and κ-caseins in the case of Bos taurus. Remarkably, the relative proportions of these caseins vary significantly among different species. Moreover, the primary sequences of αs1, αs2, and β-caseins exhibit substantial inter-species diversity, indicating a rapid evolutionary process stemming from a common precursor gene. In contrast, κ-caseins possess distinctive characteristics, implying a separate origin and role in stabilizing micelle structures.
The precision fermentation industry has long focused on the recombinant production of bovine caseins. However, the milk composition of placental mammals exhibits substantial variability in protein, fat, and sugar content, as well as diverse casein gene orthologs. This variability raises the possibility of alternative casein forms within Eutheria, which may be better suited for deployment in recombinant expression systems.
In the pursuit of this objective, the selection of β-casein and κ-casein proteins from various mammalian species was undertaken for recombinant production in Pichia pastoris
Production and Characterization of Polyhydroxyalkanoate Bioplastic from Palm Sludge Oil
No full textThe use of plastics has skyrocketed since its discovery in the 1900s and it can now be seen everywhere across the globe being used for many domestic as well as industrial applications.
The overuse along with the unwise behaviour of discarding this material has caused negative impacts to the environment such as degradation of ecosystem affecting the flora and fauna of the Earth as well as giving rise to heavily fluctuating climatic conditions. As an attempt to combat the undesired outcomes from the use of these commodity plastics, many researches were devoted to the development of bioplastics made from natural resources that are fully biodegradable. Polyhydroxyalkanoate (PHA), a type of biodegradable bioplastic that possesses many types of monomers has gained the limelight due to its ability to be accumulated naturally in various different microorganisms under certain nutrient limiting conditions. In particular, the copolymer of this PHA, Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), P(3HB-co-3HHx), has been studied vigorously due to its prominent resemblance to the commodity plastic on the basis of physical and mechanical properties.
Nevertheless, the production of this copolymer was bottlenecked by the high cost of production in which most of it is contributed by the cost of carbon source used. Therefore, many researches were performed in testing cheap and renewable resource especially oilbased material as it has been reported to result in high yields of this PHA synthesized. This study focuses on the use of a by-product of the palm oil industry, which is the palm sludge oil (PSO) in the making of this PHA copolymer using a recombinant strain of Cupriavidus necator;
a natural producer of this polymer. In addition to that, monomeric and physical characterisation of the PHA synthesized was performed in order to assess the PHA bioplastic produced from this possible feedstock
Personality Traits and Work Engagement among Human Services Workers: The Role of Coworker Support
No full textIt has been increasingly important to study the well-being of workers in the human services industry as the society benefits from their care and effort abundantly. Most research on human services workers has been focused on the topic related to mental “un-well being” such as exhaustion and burnout, instead mental “well-being”. However, lately a more positive approach of work engagement was introduced as a form of positive psychology. Since previous studies of work engagement have focused mainly on its environmental factors, this study attempted to explore the construct from another perspective which is the personality differences (extraversion and neuroticism). The main objective is to answer the question of why some individuals are more engaged than others while working in the same conditions. Moreover, the moderating effect of perceived coworker support as a form of social support is also examined in the model. A total of 246 nurses and caregivers working in Germany participated in an online survey. Findings show that extraversion and neuroticism are significant predictors of work engagement which indicates that extraverted workers are more engaged compared to the ones with high level of neuroticism. Coworker emotional support was found to buffer the negative effect of neuroticism on work engagement. However, there is no evidence of a moderating effect from coworker instrumental support on the relationship between personality traits and work engagement. The result of this study can be useful particularly for practitioners who may benefit from designing training programs that foster helping behavior among workers hence improving their work engagement
