Instead of focusing on subordinate attributes as a substitute for leadership theory, this study examines leader＇s human capital attributes as a leadership contingency variable. This paper offers a fresh perspective to contingency leadership literature by exploring a new set of variables. Addressing leader-member exchange （LMX） rather than the conventional focus on leader＇s behaviors, this study examines previously untested contingency variables. Using a matched sample of leaders and employees from Portuguese firms, this study examines leader＇s education and leader＇s organizational tenure as alternatives for LMX with assessed job performance and organizational citizenship as dependent variables. Testing new independent variables sheds additional light on contingency approaches to leadership; as a result, this paper improves the current state of research on contingency leadership. Results seem to indicate that leader＇s education is an alternative for LMX as well as suggesting that the leader＇s organizational tenure improves LMX. This paper proposes that research focusing on the substitute for leadership may need to examine a different set of variables to determine the viability of contingency approaches to leadership.展开更多

Agents are regarded in MDGDE as special objects having more autonomy, and taking more initiative. Design of the agent involves three levels of activities: logical analysis and design, physical analysis, physical design. This classification corresponds to domain analysis and design, application analysis, and application design. Agent is an important analysis and design tool for MDGDE because it facilitates development of complex distributed system—the mobile robot. According to MDGDE, we designed a distributed communication middleware and a set of event-driven agents, which enables the robot to initiate actions adaptively to the dynamical changes in the environment. This paper describes our approach as well as its motivations and our practice.展开更多

Consequently, educational programs for teaching engineers should work with the fact that the capability of communicating with people with different background competences is important, nevertheless the engineering education has traditionally focused on technical skills rather than on personal development. In order to reform the B.Sc. courses to guide students to become better and more efficient engineers on all levels, the DTU （Technical University of Denmark） and Helsinki Metropolia University of Applied Sciences （Metropolia） modified their education according to the CDIO （conceive, design, implement and operate） approach in the autumn of 2008. The CDIO pedagogy encouraged to develop an interactive course in interpersonal skills, where the students have to take an active part in the exercises as well as involve themselves in the interactive communication process. The course consists of various exercises from which the participants will develop their awareness and knowledge of communication. It is the intention to give the students a personal understanding and idea of a different approach to communicating between people. The students evaluated the course, and the four key questions dealing with the quality of the course show a very high satisfaction with the instruction. The grades one and two （1 best/very much, 5 worst/very little） of the responses ＂to these four questions are ranging on average from 69.5% to 88% （on a yearly basis）. The positive responses indicate that the students are very satisfied with the course recognizing the need for education on international communication.展开更多

It is really unbelievable that in the period of information and scientific society such criteria do not exist and there are no fixed rules for assessment of scientific activities. However, in many fields of science, e.g., in reviews of scientific works or papers, reviewers are asked to assess whether or not the submitted work or text is scientific. Naturally, this decision is not objective even if done by leading scientific individuals. Scientists may possess rather different individual criteria, and especially in doctoral studies, but not only there, it is desirable to make the review more objective. A doctoral thesis should be accepted only in case it brings some scientific achievement. Keeping in mind how difficult it can be to formalize and evaluate science, the authors try to propose attributes of scientific activities and to formulate some basic recommendations how to assess scientific work. Of course, the paper does not intend to formulate any generally imperative rules, but rather to start a broader discussion of these topics.展开更多

文摘The current research attempts to revitalize contingency leadership theory. Instead of focusing on subordinate attributes as a substitute for leadership theory, this study examines leader＇s human capital attributes as a leadership contingency variable.
