In this paper, we show that sequence pair (SP) representation, primarily applied to the rectangle packing problems appearing in the VLSI industry, can be a solution representation of precedence constrained scheduling. We present three interpretations of sequence pair, which differ in complexity of schedule evaluation and size of a corresponding solution space. For each interpretation we construct an incremental precedence constrained SP neighborhood evaluation algorithm, computing feasibility of each solution in the insert neighborhood in an amortized constant time per examined solution, and prove the connectivity property of the considered neighborhoods. To compare proposed interpretations of SP, we construct heuristic and metaheuristic algorithms for the multiprocessor job scheduling problem, and verify their efficiency in the numerical experiment. 相似文献

This essay deals critically with the use of the term “systemic”. Initially three basic system-theoretical concepts used in consulting and counseling are introduced: the problem of complexity, the construction of realities and the paradigm of functionality. Subsequently, the author demonstrates, that these principles have always been integral components of the most early pedagogical/psychological consulting practices. The addition of the term “systemic” is thus often superfluous and misleading. 相似文献

The effect of a positive day reflection as a technique of positive psychology has been found repeatedly. The qualitative study is based on a sample of 74 participants and shows which kind of experiences people make during and after this exercise. For this purpose, participants were instructed to reflect their day based on four specific questions (4-Evening-Questions) every evening over a period of two weeks. Subsequently, individual experiences were collected and analyzed qualitatively. The results show that the exercise leads to a sensitization of perception, a change in the interpretation of situations as well as in one’s own actions. 相似文献

By analyzing cinema films, specific organizational cultures can be illustrated. The culture of prison as a “total institution” is explained on the basis of the movie “The Shawshank Redemption” (1994). With regard to the developing friendship between the former banker Andy Dufresne who is innocently convicted and the homicide delinquent Ellis Boyd Redding typical characteristics of a total institution are pointed out. Furthermore, the psychological function those characteristics serve for employees, inmates and even for the society as a whole is analyzed. Central to this interpretation is thinking of the prison as a father substitute. Many interactions become comprehensible viewed in this context. Additionally, the prison represents a huge object of projection which facilitates the collective release of aggression. 相似文献

This paper focuses on coaching and similar types of consulting in the field of personnel development. First the author discusses the current debate concerning personnel development; finally she describes the special goals, target-groups and issues of coaching, clinical supervision, mediation, mentoring and outplacement-consulting within the field of personnel development. 相似文献

The program “Mentoring for female junior executives at schools” in Hamburg has the goal of recruiting more female executives for schools in Hamburg. As a headmaster of a high school the author has attended this program as a mentor. She discusses the following questions: What are the differences between mentoring and coaching? Where are the limits of mentoring? When is coaching the better method? The main result is, that the mentor has to be very attentively of his position as a member of the organization. He has to decide, if he can advise the mentee for example in conflicts with superiors or if a coach could do a better job. A missing link in the mentoring program is the analysis of the culture of organizations, because this is an important factor for a successful start into the new function. 相似文献

Government institutions have introduced multichannel environments over time following trends and technological innovations. These public multichannel environments often neglect specific channel characteristics and potentials and thus miss the opportunity to make full use of a strategic channel integration and combination with a focus on customer value creation. This study offers a systematic approach to establish an integrated public multichannel system not only taking into account user preferences, habits and their environment, but also the respective channel issuer and the characteristics of channels and public interfaces. Against this background, the study presents a systematic approach to expand services and channels according to their capacities, and provides academics and practitioners with a framework on public multichannel strategies. 相似文献

This paper looks beyond more traditional evaluation activities to focus primarily on evaluation up front. It suggests that the early appraisal of an investment case or a project should apply essentially the same evaluation criteria that will be used in ex post evaluation, and thus increase the likelihood of a successful project outcome. However, the initial plan might be altered as result of subsequent analysis, assessment, negotiation, positioning, and the exercise of power. The last part of this paper presents an empirical study of 23 projects, which examines the complexity of processes that occur in the idea- and decision phases. 相似文献

We investigate organizational determinants and performance effects of formal target agreements for employees based on the IAB establishment panel, a representative panel of German establishments. The results show that establishments with a high employee turnover rate, a large proportion of temporary workers, and a highly qualified workforce are significantly more likely to implement target agreements. Also, establishments with works councils installed are more likely to do so, controlling, among others, for firm size. Concerning organizational performance, we apply a first-difference and a fixed effects approach and find that establishments that implement target agreements achieve around 5 % higher total sales compared to firms that did not introduce this practice. Hence, organizations seem to benefit from the implementation of formal target agreements for employees. 相似文献
