The author surveys and compares the legal professions of 15 nations, including both civil law and common law countries. The essay is organized around the ways that legal professionals control their markets—first by controlling "production of producers" or who and how many enter the profession (with formal education or apprenticeship requirements, examinations, access to entry-level positions). Legal professionals also control "production by producers"—both external competitors and lawyers themselves. This occurs, for example, through definition and defense of the professional monopoly, control of competition between licensed professionals, and creation of demand. The discussion takes place against the background of the legal profession's recent history—assessing changes in its composition (by race, age, gender), in lawyers' practice settings, in the categories of work they perform, and in the income and status associated with these categories and with the profession in general.  相似文献

This report presents, discusses and extends strategic models for representing the process of merging records from different sources when confidentiality of the records is required by law or custom. Examples and variations on the models cover simple situations, such as eliciting anonymous data from previously identified respondents, as well as more complex merge operations, such as merging files from different data archives and merging data under code linkage systems. The versatility and potential corruptibility of the models are also discussed.Supported by NSF Grants GI29843 and GS320-73X. Professors Eli Rubenstein, Donald T. Campbell, and Lance Hoffman were generous in providing advice on earlier drafts of the paper. However, views expressed here do not necessarily reflect the views of the sponsoring agency or of these individuals.  相似文献

Because of difficulties collecting sales taxes on Internet sales, several states have engaged in an effort (the Streamlined Sales Tax Project, SSTP) to simplify their sales tax systems. One hope among SSTP proponents is that a simplified system will result in Internet vendors voluntarily collecting the sales tax. We address two issues:
  • ? Will states adopt the extensive reforms proposed by the SSTP?
  • ? Will vendors voluntarily collect the sales tax?
We argue that states are unlikely to adopt extensive reforms, but if they did, many vendors would voluntarily collect sales taxes.  相似文献

In response to Nagin's comment on our paper, Methodological Sensitivities to Latent Class Analysis of Long-Term Criminal Trajectories, we reconsider the robustness and validity of group-based approaches to criminal trajectories and introduce additional issues for future research. We emphasize the limitations of typological approaches and the dangers of reifying the idea of distinct offender groupings for research and policy. We also clarify misunderstandings about the use of hierarchical linear models for studying trajectories of crime. Our basic conclusion is that methods in criminology need to be more tightly linked with theory.  相似文献
