Generation Z strömt derzeit mit neuen Wertvorstellungen und hohen Ansprüchen in die Arbeitswelt ein, was Führungskräfte vor eine große Herausforderung stellt. Um sich im Fachkräftemangel zu behaupten, die jungen Talente zu rekrutieren sowie langfristig an das Unternehmen zu binden, müssen Unternehmen, insbesondere Führungskräfte die Erwartungen und Anforderungen der Generation Z kennen und diesen gerecht werden. Während die Erwartungen und Anforderungen der Vorgängergenerationen bereits analysiert wurden, sind die der jungen Generation Z unbekannt.
Um die Erwartungen und Anforderungen der Generation Z an Führungskräfte und deren Verhaltensweisen zu identifizieren, wurde eine qualitative Forschungsmethode angewandt, indem fünf Experteninterviews mit Studierenden aus der Generation Z geführt wurden. Diese wurden anschließend mithilfe einer qualitativen Inhaltsanalyse anhand von Kategorien ausgewertet.
Die junge Generation stellt hohe Erwartungen an Führungskräfte sowie deren Verhalten ihnen gegenüber. So fordern sie nicht nur klare Vorgaben hinsichtlich der an sie gestellten Erwartungen, sondern zeigen auch das Bedürfnis nach regelmäßigem Austausch und Feedbackgesprächen mit ihrem Leader. Führung sollte für Generation Z immer auf Augenhöhe stattfinden, geprägt von einer offenen Kommunikation sowie einem wertschätzenden Umgang. Zudem sollte die Führungskraft als Ansprechpartner bei Problemen und Fragen für die Generation Z zur Seite stehen.
Die dargestellten Ergebnisse der Arbeit leisten einen wichtigen Beitrag für Wissenschaftler im Forschungsfeld Generationsmanagement und helfen zudem Entscheidungsträgern im Personalmanagement die Anforderungen und Erwartungen der jungen Generation Z zu erfüllen. Somit profitieren sie nicht nur im Recruiting davon, sondern können die jungen Talente möglicherweise langfristig an das Unternehmen binden.
Iterative Signing of RDF(S) Graphs, Named Graphs, and OWL Graphs: Formalization and Application
(2013)
When publishing graph data on the web such as vocabulariesrnusing RDF(S) or OWL, one has only limited means to verify the authenticity and integrity of the graph data. Today's approaches require a high signature overhead and do not allow for an iterative signing of graph data. This paper presents a formally defined framework for signing arbitrary graph data provided in RDF(S), Named Graphs, or OWL. Our framework supports signing graph data at different levels of granularity: minimum self-contained graphs (MSG), sets of MSGs, and entire graphs. It supports for an iterative signing of graph data, e. g., when different parties provide different parts of a common graph, and allows for signing multiple graphs. Both can be done with a constant, low overhead for the signature graph, even when iteratively signing graph data.
Bei dem für dieses Schutzprofil (engl. "Protection Profile" im Folgenden PP genannt) herangezogenen Evaluationsgegenstand (im Folgenden EVG genannt) handelt es sich um einen Router, der einen Schutz gegen Online-Überwachung bietet. Der EVG-Typ ist hierbei ein handelsüblicher Internet-Router, der in Privathaushalten und kleineren Firmen eingesetzt wird. Der EVG umfasst den gesamten Router, so dass sowohl die Hardwarekomponenten als auch die Softwarekomponenten betrachtet werden. Es ist dabei irrelevant, ob es ein Modell mit integriertem Breitband-Modem ist oder ob dieses separat angeschlossen ist.
Social Media is a world-wide phenomenon which has drastically changed the way humans communicate, the availability of information, as well as a crucial tool for various businesses. This has also heavily influenced the sporting community which presents the focus of this study. The work aims to examine the self-presentation, on the media platform Instagram, of footballers from FC Bayern Munich, to gain an understanding of how athletes use this medium as a communication and marketing tool to build their brand. Instagram was chosen due to it being a platform on which users post visual images as their primary communication mechanism. There are many social media uses for professional athletes. From the sharing of personal lives, professional highlights, and opinion, to product placement and endorsements, athletes are closer to fans and consumers than ever before. Social media also puts the athlete in charge of the message, image, and content regarding their careers and their lives Ten footballers were selected against specified criteria and examined against Goffman’s theory of self-presentation (1959) to formulate the research question: “Which forms of presentation of football players of FC Bayern Munich ́s Instagram posts achieve the highest user engagement?”
Empirical research analysed the effect of different visual and contextual forms on user engagement rates.
Through the works literature review, individual hypotheses were derived and tested in a quantitative standardized media content analysis. The first 50 Instagram posts of each of the ten FC Bayern Munich football players with the most followers were analyzed using IBM SPSS Statistics software. From the visual aspect seven photo categories were developed which were examined in relation to their engagement rate with the posts. Within the contextual framework, the importance and effect of the number of tags and hashtags used were analyzed.
Findings revealed differences to previous research on an athlete ́s use of written social media outlets such as Facebook and Twitter, as the majority of visual images posted by athletes were in sporty settings, thus reflecting frontpage-performance strategies according to the self-presentation theory. Further results showed that a greater utilization of hashtags and tags do not correlate with a higher impact on the engagement rates. Personal brand management implications for athletes are examined in greater detail in the discussion.
We present the user-centered, iterative design of Mobile Facets, a mobile application for the faceted search and exploration of a large, multi-dimensional data set of social media on a touchscreen mobile phone. Mobile Facets provides retrieval of resources such as places, persons, organizations, and events from an integration of different open social media sources and professional content sources, namely Wikipedia, Eventful, Upcoming, geo-located Flickr photos, and GeoNames. The data is queried live from the data sources. Thus, in contrast to other approaches we do not know in advance the number and type of facets and data items the Mobile Facets application receives in a specific contextual situation. While developingrnMobile Facets, we have continuously evaluated it with a small group of fifive users. We have conducted a task-based, formative evaluation of the fifinal prototype with 12 subjects to show the applicability and usability of our approach for faceted search and exploration on a touchscreen mobile phone.
Despite widespread plans of big companies like Amazon and Google to develop unmanned delivery drones, scholarly research in this field is scarce, especially in the information systems field. From technical and legal perspectives, drone delivery in last-mile scenarios is in a quite mature state. However, estimates of user acceptance are varying between high skepticism and exaggerated optimism. This research follows a mixed method approach consisting both qualitative and quantitative research, to identify and test determinants of consumer delivery drone service adoption. The qualitative part rests on ten interviews among average consumers, who use delivery services on a regular basis. Insights gained from the qualitative part were used to develop an online survey and to assess the influence of associated risks on adoption intentions. The quantitative results show that especially financial and physical risks impede drone delivery service adoption. Delivery companies who are currently thinking about providing a delivery drone service may find these results useful when evaluating usage behaviors in the future market for delivery drones.
The objective of this contribution is to conceptually analyze the potentials of entrepreneurial design thinking as being a rather new method for entrepreneurship education. Based on a literature review of different design thinking concepts we carve out a generic design thinking model upon we conceptually build a new model that considers entrepreneurial thinking as a valuable characteristic.
The results of our work show that the characteristics of entrepreneurial design thinking can enhance entrepreneurship education by supporting respective action fields of entrepreneurial learning. In addition we reveal that entrepreneurial design thinking offers beneficial guidelines for the design of entrepreneurship education programs.
Grundlagen der Systemtheorie zur Anwendung transdisziplinärer Verfahren der Technikfolgenabschätzung
(2020)
The technological progress is highly responsible for how people live their everyday life. Technical innovations provide new opportunities to re-design all areas of life and because of that the society has to adjust to these changes permanently. These days, due to the fact that there is a changeover from analog into digital processes, this circumstance is highly relevant. However, it is not always clear whether a technological innovation just entails chances or involves risks, too. The research field of technology assessment pursues the goal to examine the influence of technological innovations on the society. For this purpose, unpredictable consequences of a technology need to be anticipated in advance to provide the opportunity of earlier reactions. The core of this thesis a discussion about a project based approach of technology assessment. Additionally, it is being investigated whether and how systems theory approaches can be used to improve predictions in the research area of technology assessment. Therefore, the question of how reliable forecasts are in this kind of context will be answered. Moreover, there is an investigation if an added-value can be created through performing system thinking. As a methodical approach a literature review has been performed. Furthermore, experts were questioned in an interview and by e-mail to gain an insight in the practical work of technology assessment. Based on the elaborated project structure, for each part of the project was examined if significant results can be maintained through the sophisticated use of principles of the systems theory. The analysis of this paper has shown that the results of a technology assessment may have more reliable forecast value in comparison to an investigation without proper consideration of system thinking. Especially, the understanding of a system during the phase of conception of a project can be crucial for the positive outcome for the results of technology assessment. This master thesis represents the theoretical point of view regarding topics technology assessment and systems theory. An application test for the validation of the results in the practical work of technology assessment is recommended.
In order to enhance the company’s appeal for potential employees and improve the satisfaction of already salaried workers, it is necessary to offer a variety of work-life balance measures. But as their implementation causes time and financial costs, a prioritization of measures is needed. To express a recommendation for companies, this study is led by the questions if there are work-life balance measures which have more impact on employee satisfaction than others, how big the relative impact of work-life balance measures on job satisfaction in comparison to other work and private life variables is, if there is a relation between the effectiveness of measures and their use and if there is a difference between the measures which are most important from the employees’ perspective and the companies’ offers.
These questions are formulated in eight research hypotheses which are examined in a quantitative research design with online survey data from 289 employees of fifteen different German companies. The formation of a hierarchy of the effectiveness of measures towards job satisfaction as well as the investigation of the relative impact in comparison to other variables is performed using a multiple regression analysis, whilst the differences between employees’ expectations and the availability of offers are examined with t-tests.
Support in childcare, support in voluntary activities and teambuilding events have a significantly higher impact on job satisfaction than other work-life balance measures, and their potential use is higher than the actual use which leads to the conclusion that there is yet potential for companies to improve their employees’ satisfaction by implementing these measures. In addition, flexible work hours, flexible work locations and free time and overtime accounts are the most important measures from the employees’ point of view and already widely offered by the surveyed companies. In general, the overall use of the available measures and the quantity of offered measures are more important with regard to job satisfaction than the specific kind of measure. In addition, work-life balance measures are more important towards job satisfaction for younger people.
