The Second General Conference of the UNIDO held in Lima in 1975 declared that the share of developing countries in total world industrial production should reach 25% by the year 2000. The model presented in this article has been constructed in order to investigate whether this target is consistent with other more generally accepted goals of development and is feasible within the area of production and trade possibilities.The model is a dynamic, multisectoral, multiregional input-output model. It focuses on the impacts and mutual consistency of targets of growth, regional income distribution, industrialization, consumption levels, and trade. In the empirical application three periods, three regions, and nine sectors have been distinguished to produce intersectorally, interregionally, and intertemporally consistent accounts for the main variables. Since the study is concerned with the maximum possible growth of industrial output of the developing countries, a linear programming approach has been used.The report is organized as follows. After an introduction, the second section describes the mathematical model. The third section contains a detailed explanation of the data basis and of the assumptions made to stimulate the model. The numerical results of the model are discussed in the fourth section, and the main conclusions are given in the fifth.  相似文献

This essay intends to define the role of entropy, in particular, the role of the maximum entropy criterion with respect to decision analysis and information economics. By considering the average opportunity loss interpretation, the basic hypothesis for Shannon's derivation can be derived from properties of decision problems. Using the representation Bayes Boundary it is possible to show that selecting a single probability from a set by the Maximum Entropy Criterion corresponds to a minimax criterion for decision-making. Since problems of randomly accessing and storing information as well as communicating information can often be stated in terms of coding problems, this result might be used to develop strategies for minimizing retrieval time or communication costs.  相似文献

To understand children's peer group affiliation, this study examined to what extent children in naturally occurring groups resemble each other on bullying, likeability, and perceived popularity. Participants were fourth‐ to sixth‐grade pupils (N = 461). Peer groups were identified using the social cognitive map procedure. Resemblance on bullying, likeability, and perceived popularity was evaluated by means of variance components models. Resemblance in peer groups was strongest for perceived popularity, followed by bullying and likeability. Moreover, resemblance on bullying could for a large part be attributed to the high‐perceived popularity of the group, and to a lesser extent, to the low likeability of the group. It is concluded that children showing bullying seem to affiliate with each other most of all to attain or maintain their position in a perceived popular peer group. Results stress the importance of considering the functionality of bullying from a group perspective.  相似文献

We use an experimental design to analyse the effect of symbolic capital of a nation’s higher education system and of single universities on students’ opportunities for international mobility. Fake applications of international doctoral students were sent to German sociology professors, who were asked to serve as supervisors during a research visit in Germany. Our fake applicants come from four different universities: Yale, Pennsylvania State University, National University Singapore, and Vietnam National University Hanoi. The results show that applicants from both US institutions get more positive, more informative and more personal feedback than applicants from Singapore and Vietnam. Moreover, the symbolic capital of a university seems more important than the quality of a specific department, which is problematic in normative terms.  相似文献

A German version of the Organizational Citizenship Behavior Questionnaire (GOCBQ) is developed and tested. Study 1 was conducted with 150 students working together in 39 project groups. The results show that the internal consistency and test-retest-reliability of the GOCBQ are good. Moreover, the GOCBQ measures a general altruism orientation which can be interpreted as a stable trait. The GOCBQ does neither correlate substantially with demographical variables nor with extroversion or neuroticism. Instead, substantial correlations are registered with mood and group atmosphere. In study 2 results from study 1 were cross-validated with data from 128 voluntary and professional helpers, in study 3 with data from 43 professionals. Implications for future research and applications in working life are discussed.  相似文献

The relation between citizenship and labor market position is complex. Besides a causal impact from citizenship towards labor market position, several selection mechanisms may cause particular immigrants to choose for naturalization. We investigate the empirical relation on the basis of German and Dutch survey data. For the Netherlands we find a positive relation between citizenship and labor market position, while for Germany we find mixed results as citizenship is negatively related to tenured employment. The contrasting results may be explained by institutional differences. In Germany, economic self-reliance is more strictly required for naturalization than in the Netherlands. This may lead to a stronger incentive to naturalize for workers with a temporary contract in Germany.  相似文献

Objective. To understand how adaptation/assimilation, disruption, and diffusion interact to produce changes in fertility levels among successive generations of Mexicans and Central Americans in the United States. Method. Using restricted access data that link individual data (CPS) to neighborhood data (census tracts), we examine the role of generation, personal characteristics, and neighborhood characteristics in determining children ever born (CEB). Results. There are significant differences in fertility across generations and, to a lesser extent, between women who live in ethnic enclaves and those who do not. Once personal characteristics are considered, the independent effect of generation on fertility is nearly eliminated. Personal characteristics dominate neighborhood characteristics in their ability to predict fertility. The most consistent predictor of CEB at the neighborhood level is the percentage of Hispanic adults. Conclusions. Personal characteristics dominate fertility change across generation, and were it not for increases in educational attainment, fertility might be higher in successive generations rather than lower or unchanged.  相似文献

Before a troubled State-owned company can be privatized, the management dimension must be examined. The privatization strategy must be closely linked with the overall business strategy to ensure that the opportunities afforded by the operation provide for long-term profit enhancement. The logic behind the state-owned enterprise is described and the objectives of privatization, the pros and cons, are analysed.  相似文献
