Die Reputation von Unternehmen ist einer zunehmenden Gefahr ausgesetzt, die sich aus der (unreflektierten) Nutzung sozialer Netzwerke durch die eigenen Mitarbeiter ergibt. Die Treiber und Hemmnisse eines solchen Nutzerverhaltens von Arbeitnehmern in sozialen Netzwerken wurden bislang nur unzureichend erforscht. Der vorliegende Beitrag untersucht unter Verwendung der Boundary Theorie am Beispiel der Plattform Facebook, inwieweit die Persönlichkeitsmerkmale Neurotizismus und Extraversion, die Organisationsidentifikation und die Unternehmensreputation ein zustimmendes Verhalten von Nutzern begünstigen. Eine experimentelle Online-Studie mit 494 Probanden zeigt, dass insbesondere eine hohe Unternehmensreputation und Organisationsidentifikation zu einem erhöhten zustimmenden Verhalten führen.
Digital happiness
(2016)
Emotions in the digital world gain more and more importance by the accelerating digitalization of recent years. In everyday life as well as professional and educational environments, the use of media is almost inescapable. This work takes a closer look to the still relatively unknown topic, “Digital Happiness“. In the literature emotions in the digital world are studied increasingly, but concerning the topic of “Digital Happiness” there are not many insights.
In this research the differences between communicating emotions through digital media and face-to-face communications, as well as their impacts, are investigated. The perception and expression of emotions in the real and digital world are considered. Furthermore, a first definition of “Digital Happiness” and a model with the associated determinants that influence “Digital Happiness” is developed.
To achieve these goals, a literature analysis by the method of Webster & Watson (2002) is performed. Therefore, 15 articles are selected and analyzed in more detail to illustrate the current state of research. These articles are organized into a concept matrix. In addition, special phenomena, such as Quantified Self, are closely considered in order to determine other factors. Based on the literature analysis, a qualitative study by the method of Mayring (2014) is performed. It is developed into an interview guideline that serves as the basis for the investigation of the established determinants of the literature analysis. This is confirmed or refuted by 30 interviews with users of information and communication technologies. With the help of the interviews, a large part of the determinants in the literature can be confirmed. Moreover, some new determinants are identified. These results are included into the final model. This model provides a basis for further research in the field of “Digital Happiness“. Finally, different implications for research and practice are found, which reveal the need of further research.
Prototyp einer generischen Recommendation Engine basierend auf Echtzeit-Assoziationsanalysen mit R
(2016)
In dieser Arbeit wurde unter Verwendung der Programmiersprache R ein Prototyp zur Erstellung einer Recommendation Engine zur Aufdeckung von Assoziationen innerhalb einer gegebenen Datenmenge entwickelt. Die Berechnung der Assoziationen findet hierbei in Echtzeit statt und des Weiteren wurden die Analysefunktionen generisch programmiert, um ein schnelles Einbinden und einfaches Parametrisieren von Datensätzen zu ermöglichen. Die Entwicklung fußte auf der grundlegenden Motivation, Data Mining Methoden wie das Assoziationsverfahren teilweise zu automatisieren, um damit generierte Lösungen effizienter umsetzen zu können. Der Entwicklungsprozess war insgesamt erfolgreich, sodass alle Grundfunktionalitäten im Sinne eines evolutionären Prototypings vorhanden sind.
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.
Die Entstehung von Gründungsteams wird bisher lediglich als Abfolge von Suche, Auswahl und Gewinnung von Gründerpersonen verstanden. In der vorliegenden Arbeit wird auf Basis von 47 interviewten Gründerpersonen ein neues Verständnis für die Entstehung von Gründungsteams geschaffen. Dabei wird im Stil der Grounded Theory das bisher vorherrschende Model der Teamentstehung maßgeblich erweitert. So wird eine neue Art der Unterscheidung von Grünerpersonen entdeckt, welche auf die Intention von Teammitgliedern abzielt. Zudem zeigt sich, dass Teams in einem iterativ-epiodischen Prozess entstehen und Veränderungen von Teamzu-sammmensetzungen Bestandteil der Entstehung sind. Aufgrund der in dieser Arbeit geschaffenen neuen Erkenntnisse zur Teamentstehung können Handlungsempfehlungen für Gründerpersonen und die Gründungsförderung gegeben werden. Zudem werden neue Untersuchungsgebiete für Gründungsteams eröffnet, die das hier entwickelte Modell als Bezugsrahmen für weitere Forschung nehmen können.
Die vorliegende Arbeit beschäftigt sich mit der Betrachtung der Rolle von Vertrauen zwischen den Kapitalnehmern und Kapitalgebern auf einer der größten Crowdfunding-Plattformen, Kickstarter. Kernthema ist die Beantwortung der Forschungsfragen, wie das Vertrauen zwischen den Kapitalgebern und Kapitalnehmern im Kontext von Crowdfunding entsteht, welche Faktoren das Maß von Vertrauen in dieser Beziehung beeinflussen und welche Signale für die Vertrauensbildung verantwortlich sind. Das Ziel dieser Arbeit besteht darin, das von Zerwas, Kilian und von Kortzfleisch 2015 vorgestellte konzeptuelle Modell der Einflussfaktoren von Vertrauen im Kontext von Crowdfunding aus Sicht der Kapitalgeber zu überprüfen und gegebenenfalls zu erweitern.
Auf Grundlage einer Literaturrecherche und qualitativer, leitfadenorientierter Interviews werden die gesammelten Daten diskutiert, bestehende Faktoren verifiziert und weiterführend neue Faktoren und Signale identifiziert, die die Bildung von Vertrauen auf Crowdfunding-Plattformen beeinflussen.
Als Ergebnis werden die Überarbeitung sowie Erweiterung des Ausgangsmodells um die neuen Faktoren geographische Nähe, Vermittlerqualität und Verständnis vom Konzept Crowdfunding vorgeschlagen. Anhand der Häufigkeit der Erwähnung und Relevanz der Faktoren und beeinflussenden Signale in den durchgeführten Interviews wird weiterführend eine Gewichtung der Einzelfaktoren vorgenommen. Abschließend werden Implikationen und Bedeutung für Wissenschaft und Forschung diskutiert.
How entrepreneurs become successful with their business ideas has been a topic of discussion within entrepreneurial research circles for many years. Business success has been related to psychological characteristics and many research findings have explained how people become entrepreneurs and furthermore, how they find success in regards to their business ventures. People always wanted to know what defines an entrepreneur and more importantly, what is needed to become a successful entrepreneur. Curious minds began to search for the recipe for success. Personality Traits have been researched for years, leading to the discovery of many diverse and distinct forms which are still recognized today. Researchers compared the Behavioral Approach or the analysis of demographical characteristics to success.
This raises the question of what an entrepreneur needs to become successful which is made more difficult due to the fact that entrepreneurship and who an entrepreneur is can be difficult do define exactly. Entrepreneurs are diverse and distinct individuals that each possess their own characteristics, behavior and reasons for starting a business. Many people assume that it is just someone who starts their own business. While partially correct, this only scratches the surface of what it is to be an entrepreneur.
This thesis answers the following three research questions: 1. Which personality traits were found in the almost sixty years of researching? 2. What triggers do entrepreneurs need for starting a new business? 3. Which factor makes the entrepreneur successful with their business idea? Also, reading the thesis, one may gain a better understanding of what entrepreneurship is, what defines an entrepreneur and what one needs to become a successful entrepreneur.
In this thesis the reviewing literature method developed by Wolfswinkel et al. (2011) was used to identify suitable literature and references for the main chapters. For that the five stages of the grounded-theory method for reviewing the literature were used in an iterative fashion. In step one inclusion and exclusion criterias for literature were defined. Then literature was searched matching the criterias of step one. In step three the samples were refined. Then in step four the found literature was analyzed and coded before the results of this research was presented in the following text. Many entrepreneurial personality traits were discovered and confirmed during the studies conducted over the last sixty years, these include but are not limited to Need for Achievement, Locus of Control, or risk taking propensity. Motivation is clearly the main trigger to start your own business. During the studies reasons were discovered of how and why an entrepreneur may become successful outside of posessing the right combination of traits. For example: having human, financial and social capital, an entrepreneurial behavior and the right economic conditions to start a business that will survive for more than five years.
