Nowadays, team-based approach is a common organizational strategy in many organizations. The study of the effect of team characteristics on team performance becomes a popular issue for many researchers. In order to ensure high performance, it is believed that the organizational strategy has to coordinate well with the characteristics of the team members. Aiming to determine the significance of work values, this study uses team members¡¦ work values as a variable, and tries to establish a relationship among work values, team characteristics and team performance. The results of the study are as follows: 1. The work values of members with different educational background and tenure are not the same. 2. Work values correlates with team characteristics. 3. Team characteristics correlates with team performance. 4. Some work values correlate with team performance. 5. Team characteristics have an effect on team performance. 6. Work values have an effect on customer orientation and team confidence. 7. Process-oriented work values have an effect on team characteristics. 8. Goal-oriented work values have an effect on the improvement of team performance. 9. Process-oriented work values have an effect on work quality, work values and innovation factors.

In knowledge economy, organizational knowledge is considered to be a critical strategic resource which may help the organization to achieve competitive advantage; therefore, knowledge sharing, as one of the knowledge management processes, attracts the attention of both researchers and practitioners. Knowledge sharing may bring many benefits such as personal development for the employees and knowledge accumulation for the organization. However, at the same time it is very challenging because employees may be very mobile, too occupied to engage in knowledge sharing, or just unwilling to share their valuable knowledge. Nevertheless, although many organizations have started to invest heavily in various knowledge sharing mechanisms, quite often these processes are not effective because various organizational and individual factors impede the usage of those mechanisms. This study seeks to increase the understanding of how and which of such factors affect knowledge sharing in voluntary project-based organizations. Ten in-depth interviews have been conducted with the project managers in AIESEC, the largest international student organization, in order to find out what KS mechanisms they use, and what enables or hinders KS in this organization. It was found that in this organization KS takes place at all organizational levels, and the most popular KS mechanisms are documents and social interaction. Various documents include planning and tracking tools, proposals for sponsors, budget spread-sheets, feedback forms from participants and companies, and reports about functional areas. Social interaction comprises individual and group meetings, including trainings, coaching or mentoring, conversations over the phone and software Skype, discussions in conferences and communication in social groups online. So there is a balance between the KS mechanisms used to personalize and codify knowledge. However, the individualized KS mechanisms dominate on the individualization- institutionalization dimension. Also AIESEC members share all types of knowledge: tacit and explicit, individual and collective. Factors affecting KS can be categorized in 5 groups: Organizational context, Interpersonal and Team characteristics, Cultural characteristics, Individual characteristics, and Motivational factors. As KS in AIESEC takes place quite intensively, not surprisingly more KS facilitators were identified. The most significant ones in each group are as follows: the organizational culture and structure; diversity and strong social ties; willingness to help, and structure and exactness; self-efficiency and personal characteristics such as talkativeness, open-mindedness, empathy, motivation, responsibility and ambitiousness; perceived personal benefits, interpersonal trust, and organizational commitment. The few factors identified that might impede KS in AIESEC are the lack of time, lack of KS regulation and some negative cultural attitudes.

The dissertation examines the impact of Organizational Life Cycle (OLC) and the Country Socio Economic Characteristics (CSEC) on Top Management Team (TMT) Characteristics. The dissertation first elaborates and establishes the theoretical link between Organization Life Cycle, Country Socio-Economic Characteristics and characteristics of TMT. Second, a quantitative empirical study is conducted to test the OLC phases and CSEC impact on the TMT characteristics through characteristics. The dissertation outlines a detailed research methodology based on the state-of-art in the area of OLC, TMT and CSEC that will be implemented to answer the key research questions in regards to the scope of the doctoral thesis. Data set is collected from the 300 largest Swiss, German and Czech companies at year-end 2011, including detailed data on the country socio economic characteristics and career backgrounds of all TMT members (executive boards) at these companies at the end of 2011. A detailed procedure is developed to accurately classify organizations at different lifecycle phases, drawing extensively on existing literature and scales. Multilevel data analysis techniques are employed to understand how the different organization lifecycle phases influence both the level of TMT characteristics as well as changes in TMT composition and diversity due to inbound and outbound mobility of top managers over time. Substantial research synergies and knowledge transfer effects expected to emanate from this dissertation. In the dissertation regression and correlation analysis are applied for each phase of the companies' OLC in Switzerland, Germany and the Czech Republic. The dissertation states that more mature the company is more diversified the TMT are regardless the country. Also, the country impact has its own role in the relationship between the OLC and TMT characteristics which is expressed by the findings that Switzerland and Germany are more diversified than the Czech Republic in terms of TMT characteristics as gender diversity, age diversity, nationality diversity, education background of the TMTs, TMT dominant functions and TMT career length. The doctoral thesis contributes to the research by revealing relationships between TMT, CSEC and OLC theories. Also it develops methods and techniques for finding the interconnections between the OLC phases, CSEC with the TMT characteristics and the dissertation outlines the future research gaps in the area of TMT.

This dissertation examines the ways international research collaboration affects the ability of Colombian research teams to produce bibliographic outputs, and to contribute to local knowledge. Research hypotheses are tested using Zero Inflated Negative Binomial Regression models to account for the effects of international research collaboration on team output while controlling for team characteristics, partner characteristics, scientific discipline, sector, the characteristics of the teams' home institution, and team location. The study uses control groups and the Propensity Score Matching approach to assess the overall impact of international research collaboration on research team performance while controlling for the effects of endogeneity and selection bias. Results show that international research collaboration is positively associated with both team output and teams' ability to contribute to local knowledge. The study shows that such effects depend on the type of collaboration chosen and the type of partner involved. Particularly, it shows that while co-authoring with colleagues located overseas or receiving foreign funding positively affects team performance, hosting foreign researchers does not seem to affect a team's productivity or its ability to contribute to local knowledge once all other variables are held constant. It also finds that collaborating with partners from the South yields greater productivity counts than collaborating with partners from the North, but that collaboration with partners from northern countries is strongly associated with a team's ability to contribute to local knowledge, while collaboration with partners from southern countries is not. Theoretical and policy implications of these and other counterintuitive findings are discussed.
