Master's Thesis from the year 2002 in the subject Leadership and Human Resources - Miscellaneous, grade: 1,0 (A), Bielefeld University (Applied Computer Science), language: English, abstract: This study examines what factors determine the choice of governance structure made byalliance partners in the ICT-industry. First, the explanatory power of the transaction costtheory, the resource-based view, the structural contingency approach, strategic choice theory,resource dependence theory, organisational ecology and principal agent theory to answer thisquestion is surveyed. A deeper analysis using transaction cost theory, resource-based viewand structural contingency approach is employed to develop three models of alliancestructuring. Propositions related to the models are then tested on a sample of 101 strategicalliances in the ICT-industry. The findings suggest that there exist five influential factors: (1)the existence of alliance-specific investment by the partners, (2) the number of functionalareas contained by the alliance, (3) a limited duration of the alliance, (4) the type of resourcescontributed by the partners, and (5) uncertainty of the tasks of the alliance. These factors arethen recombined to form one integrated model. The success of this approach and theusefulness of such a modelling approach in general are discussed alongside future directionsfor research.

Diploma Thesis from the year 2003 in the subject Business economics - Investment and Finance, grade: 1,0 (A), Bielefeld University (Applied Computer Science), language: English, abstract: This paper critically reviews approaches for the evaluation of investments in informationsystems prior to their implementation. First, the ground for the review is prepared byexamining characteristics of evaluation, information systems and value. A classification of 54evaluation approaches identified in English and German literature is then presented. Examplesof each class are reviewed and their advantages and drawbacks are discussed. Their use inevaluation practice is analysed through the examination of empirical studies and directions forfuture research are given. Today, a significant share of corporate funds is spent on the implementation, upgrading andmaintenance of an information system (IS). Recent studies show that in 2001 the IS budget ofcompanies worldwide accounted for an averaged 8.8% of total corporate revenues (cf. CSC,2001). Consequently, a thorough evaluation of investments in information systems before,during and after the implementation of a project is important. However, the normativeliterature reports a great deal of difficulty in the appraisal of these investments (cf. Irani,2002:11). Although IS evaluation has been an issue for both academics and managers formore than three decades now, there are still serious concerns about how to select projects forinvestments, how to control the development and how to measure benefits after theimplementation (cf. Farbey, 1999:189). This concern has been matched by increased researchactivity which prevailed through two broad streams. The first stream aimed to directlymeasure the payoff of IS investments for companies and came to mixed conclusions (cf. Dehning and Richardson, 2002:8). The second stream addressed the question of how ISinvestments can actually be assessed by decision-makers and particularly focussed on theresearch of evaluation criteria, evaluation methods and the very nature of the evaluationprocess (cf. Avgerou, 2000:570). Of late, several deficiencies in the field of evaluation methods have induced calls for in-depthresearch. Academics have criticised the current state of the field as being immature andfragmented (cf. Mahmood and Szewczak, 1999:491) and have thus demanded an overviewof the whole panoply of evaluation methods, together with the assumptions they depend on...[in order to enable]... the identification of gaps. (Farbey, Land and Targett, 1999: 205). [...]

In meinem Buch geht es um ein kleines abenterlustiges Seepferdchen, dass von seinem Vater eine Gesschichte über einen Piratenschatz erzählt bekommt. Irgendwann ist die Abenteuerlust so stark, dass er sich mit zwei Freunden auf den Weg macht. Es handelt sich hierbei um eine Kurzgeschichte für Kinder, sehr schön für abends als Vorlesegeschichte.

Umfangreiche Förderprogramme sollen an Universitäten ein gründungsfreundliches Klima schaffen. Zur generellen Eignung von Hochschulen als „Unternehmerschmiede“ liegen jedoch bisher kaum Erkenntnisse vor. Sascha G. Walter untersucht, ob und in welcher Weise universitäre Fachbereiche ein Gründungsinteresse ihrer Studierenden wecken können und inwiefern der Wunsch nach einer späteren Selbstständigkeit primär personenbezogenen Determinanten unterliegt. Auf Basis einer deutschlandweiten Befragung von 389 Professoren sowie 2718 Studentinnen und Studenten (an je 24 und 66 Fachbereichen) zeigt er mit Hilfe der Hierarchisch Linearen Modellierung, dass die Gründungsneigung von Studenten, nicht jedoch von Studentinnen durch fachbereichsbezogene Einflüsse direkt geprägt wird. Weitere Geschlechterunterschiede existieren in der Wirkung von individuellen Einflüssen. Abschließend präsentiert der Autor praxisorientierte Empfehlungen für die universitäre Gründungsförderung.
