Privatisation Vouchers in Russia were heavily invested in the holders' own firms. Using data from a recent survey, we show that insider control in firms privatised in 1992-4 through the voucher process (as distinct from the earlier leased buy-out method) is insecure and dependent on managers' support. For employees, investment in insider control appears to have been motivated by employment income insurance rather than expected excess returns on the equity. Managers are predominantly the same individuals as before privatisation and display considerable hostility to outside investors, probably because they fear dismissal should outsiders gain control. Despite insider control, firms are shedding labour quite rapidly through voluntary resignations. Employment dynamics appear to be unrelated to insider equity ownership. 相似文献

Using the results of a recent survey of federal employees and focus groups of the same population, this article extends previous research on the existence of a glass ceiling in the federal bureaucracy. Even when controlling for differences between the sexes in human capital factors, work habits, work opportunities, and personal circumstances, women who have been in the federal bureaucracy from zero to 10 years and from 20 to 30 years have not advanced in their professions as successfully as have men. In contrast to and departing from previous research, there is little evidence that a glass ceiling has been experienced among women who have worked in the bureaucracy between 10 and 20 years. Additional findings consistent with past literature include the fact that among women who have faced gender-based barriers, those who chose to have children during their careers have been especially disadvantaged. We conclude that the glass ceiling on the federal level, where apparent, has been multidimensional and quite subtle. 相似文献

Genetic influences on the stability of low self-control: Results from a longitudinal sample of twins
Gottfredson and Hirschi's theory contained two propositions that have been the source of an emerging line of empirical scrutiny. First, according to the general theory of crime, levels of self-control are largely determined by parental management techniques and not by biogenic factors. Second, Gottfredson and Hirschi argued that low self-control should remain relatively stable over the life course. Data from twins drawn from the National Longitudinal Study of Adolescent Health were used to test these two hypotheses. The results of univariate model-fitting techniques revealed that genetic factors accounted for between 52 and 64 percent of the variance in low self-control, with the remaining variance attributable to the nonshared environment. Further, low self-control was stable over a two-year time period (r = .64). Bivariate Cholesky decomposition models indicated that the stability of self-control was determined almost exclusively by genetic factors, and that genetic factors also explained a moderate amount of change in self-control. 相似文献

Based on data from the National Longitudinal Study of Adolescent Health (Add Health), the current study was the first to use measures of genetic polymorphisms (DRD2 and DRD4) to empirically examine the onset of crime. Net of the effects of race, age, gender, and low self-control, genetic polymorphisms explained variation in police contacts and arrest, but only among youths in low risk family environments. Moreover, youths with genetic risk factors experienced a later onset than youths without these risk factors. Borrowing from the behavioral and molecular genetics literatures, various interpretations of the findings are discussed as well as a call for increasingly interdisciplinary perspectives in criminology that encompass both sociological and biosocial frameworks. 相似文献

This article extends the debate over personality disorders as dimensional or taxonic phenomena to the study of psychopathy and relates this issue to questions surrounding whether behaviors or personality traits best represent psychopathy. Proponents of dimensional measurements of psychopathy consider personality traits to be important constructs of psychopathy, whereas proponents of taxometric measurements consider behaviors to be important characteristics of psychopathy. After a brief introduction to the measurement of psychopathy, taxometric and dimensional measurement techniques are explained, their assumptions addressed, and their strengths and weaknesses discussed. Empirical evidence for each technique is then critiqued, and methodological problems are described. It is argued that methodological problems of existing studies largely preclude conclusions regarding whether psychopathy is dimensional or taxonic. Suggestions for future research are provided to address some of these methodological limitations. This review informs readers about each measurement approach and identifies problems regarding the dimensional or taxonic measurement of psychopathy. 相似文献

In this paper, we employ resource-based and institutional theories to examine the current role of business schools in academic
entrepreneurship. In particular, we seek to identify and understand the challenges to business schools contributing to the
transfer of knowledge to enable academic entrepreneurship. Employing a case-based method, we present evidence from 42 interviews
with technology transfer officers (TTOs), business school deans, business school entrepreneurship faculty and scientists in
eight UK universities. Our empirical analysis is focused on analyzing the challenges arising from the links between business
schools and three other principal stakeholders of academic entrepreneurship (i.e., the university management, TTOs and academics
in science departments). The findings suggest that in addition to concerns about the nature of their human capital, the ability
of business schools to fill knowledge gaps in the development of academic entrepreneurship is constrained by the institutional
structures of universities which influence: the strategies of the university and the business school; links between business
schools, TTOs and scientists; and process issues relating to differences in language and codes, goal differences, incentives
and rewards, expertise differences and the content of interactions. We conclude that if business schools are to play a more
prominent role in academic entrepreneurship there is a need to develop internal university processes and policies that promote
rather than hinder internal knowledge flows between business schools, TTOs and science departments. 相似文献
