“RateMyProfessors.com” ratings of the easiness, helpfulness, clarity, overall quality, and “hotness” of 407 criminal justice and criminology faculty members from across the United States were collected. Data were analyzed to determine what faculty characteristics determined these ratings. Experience working in the criminal justice field predicted higher ratings, while years of teaching experience was predictive of lower ratings. After controlling for instructors easiness and “hotness” ratings, the instructors’ ascribed characteristics (such as race and sex) explained the greatest proportion of variance in clarity, helpfulness, and overall quality scores. Professional characteristics, such as years of experience, publication rate, and possession of a doctorate were less influential on Ratemyprofessors.com scores.  相似文献

Abstract

In recent years a number of multifactorial theories of child sexual abuse have been developed. The most influential are Finkelhor's (1984) Precondition Model of child sexual abuse; Hall and Hirschman's (1992) Quadripartite Model; and Marshall and Barbaree's Integrated Theory (1990). While all three of these important theories have a number of strengths, each has serious weaknesses that limit its ability to provide a satisfactory explanation of child sexual abuse. In this paper we attempt to integrate the best elements of the three theories into a comprehensive etiological theory, or at least the beginnings of such a theory. After outlining the concept of theory knitting we briefly summarise each of the multifactorial theories and their major strengths and weaknesses. We then develop a comprehensive theoretical framework (the Pathways Model) integrating both the overlapping and unique elements of these broad perspectives with some additional concepts derived from various psychological domains. In the final section of the paper we consider the adequacy of the Pathways Model.  相似文献

News portals should be held to the same standard of liability for defamation as other news media. Internet service providers (ISPs) enjoy blanket immunity from liability for defamation under Section 230 of the Communications Decency Act, while information content providers (ICPs) might not. Some courts have indicated, however, that a defendant who participates in developing third-party content should be classified as an ICP and thus be held liable. Confusion over the difference between an ISP and an ICP is applied to the case of news portals. This study investigates to what extent news portals should enjoy immunity from liability for defamation. To determine a news portal's exposure to liability, a continuum of involvement is proposed as a standard in which liability is based on a defendant's actions and not on the medium employed. A defendant's involvement with third-party content can be classified under the four levels of the continuum, which can guide courts in deciding whether a defendant is liable. Congress should amend Section 230 to incorporate the continuum and allow courts discretion in determining whether a defendant is immune from liability.  相似文献

Compared to China and Japan, family and population studies of pre-modern Korea have not been widely available to scholars outside Korea. As a necessary step to increase scholarship in Korean historical demography, we introduce major historical materials currently available in Korea as useful for historical studies, summarizing demographic variables provided, the type of population covered, and the historical period referred in those historical materials. In particular, we focus on genealogies and household registers that provide demographic information of Korean population before the 20th century. We describe major features of those Korean materials as demographic sources, highlighting similarities and differences as compared to corresponding Chinese historical materials. Korean historical data showing their unique features, along with comparability with other East Asian data, have potential to expand the field of historical demography in East Asia.  相似文献

The collection presents an approach to history in which the dominance of structure is replaced by the effects of human agency. Individual motives and actions are the subject of these studies. In particular, the articles focus on the economic approach of family strategies, starting with a methodological discussion of the problematic concept of strategies: how to disentangle the influence of social structure, family circumstances, and individual behavior. The conflicting interests of individuals resulted in replacing the so-called “joint utility function” with that of “bargained family decisions.” The focus of the contributions is on the labor deployment of family members. All articles deal with three factors influencing labor deployment: adaptation to the structural environment, regulation of labor within the family, and reconciliation of choices at transition points during the individual life course of family members.  相似文献

A variety of taxes levied at various dates between the 1540s and the early nineteenth century are analysed to ascertain whether the frequency with which widows and unmarried women are listed as taxpayers matches the ratio between the numbers of widows and unmarried women and the number of men in the adult population. Examination of the tax assessments indicates that the proportion of taxpayers who were women often fell well below their proportion in the general population. This applies in the case of all taxes levied between the sixteenth and early nineteenth centuries and regardless of whether a tax was assessed primarily on goods, houses occupied, or land owned or occupied. That double the proportion of female than of male householders were exempted from payment of the hearth tax on houses they occupied in the second half of the seventeenth century indicates that many women maintained households on very depleted resources. However, the proportion of taxpayers who were women amongst those paying the least tax did not usually exceed the proportion of women amongst those paying most tax.  相似文献

This article, drawing upon a quantitative survey of over 80 parliamentarians, as well as website surveys combined with qualitative interviews, explores the degree of usage of Information and Communication Technologies (ICTs) by Swedish parliamentarians. It also begins to consider any implications for party organisations and parliamentary authorities. The authors suggest that, by 2005, Swedish MPs were becoming ‘electronic parliamentarians’ and that this, combined with the growing usage of political blogs, places increasing demands upon party organisations and the Riksdag to consider the broader management and accountability issues of greater ICT usage by individual MPs. The authors argue that there is a pressing requirement for further research on these organisational and institutional dimensions by scholars of legislative studies, particularly, given the developments in ICT-advanced political systems, like Sweden.  相似文献

The article looks at the development of parliamentary institutions and procedures in Russia and the extent to which Russian politicians have been interested in learning from ‘mature’ democracies.

There are few examples of parliamentary practices being transplanted without significant adaptation. The debate in Russia on the role of parliament indicates that the idea of imitating foreign models has to compete with the powerful notion of rediscovering a national democratic tradition and both are used rhetorically to support particular interests. Parliamentary rules and practices are organically linked with party organisation, with the balance of parties at any given time, with electoral law, and with the relationship of the executive to the legislative branch. Changes in political habits take time.

International contacts are valuable because they lend confidence and authority to those who are working to build on democratic habits, but it is more important that parliamentarians and officials should find solutions which are internally consistent, which work with the grain of their own slowly evolving political culture and which reflect the most positive of their own traditions, than that they should assemble best practice from around the world.  相似文献
