This article, drawing on fieldwork in China, charts the ascendancy of Lian Tong (China Unicom), the first competitor to the incumbent Ministry of Posts and Telecommunications. Commencing with an historical overview of Chinese telecommunications, it suggests that Lian Tong's formation has been contingent upon support from key constituencies within China's political elite. The company's emergence mirrors technological trends and user pressure evident globally. It embodies the drive towards market liberalisation now evident within the Peoples’ Republic. While the Chinese policy community is sensible of the need to make haste slowly toward the goal of telecommunications competition — ‘touching stones to cross the river’ in the contemporary aphorism — the success of this ‘policy experiment’ depends both on the subtleties of Chinese politics and the construction of bold new regulatory frameworks. Lian Tong's genesis is symbolic of developments in the telecommunications sector, and maybe also more generally in the Chinese economy.  相似文献

This concept paper emerged from a Law and Human Behavior (LHB) Workshop, that was called by the journal's Editor, Richard Wiener, and held at St. Louis University on March 19–21, 1999. This workshop, which brought together 22 scholars and researchers in legal psychology, was part of James Ogloff's Presidential Initiative Project for the American Psychology/Law Society, and was supported by St. Louis University and an NSF grant. Prior to our arrival, each participant answered queries from the Editor about LHB and the field of psychology and law, and each was asked to offer five topics that were underrepresented in the journal or that we would like to see addressed in future issues. At the workshop, we were assigned to small groups, and the authors of this paper constituted one such group. The charge for all groups was to develop plans for encouraging submissions in areas of psycholegal scholarship that continue to be infrequent topics of investigation, and then to develop a concept paper. The direction our group took is captured by our title, Everyday Life and Legal Values, and within this paper we explicate the topic, identify a number of underrepresented research areas, suggest some research paradigms for investigating them, and present this within a perspectival directions frame that ties established lines of research to the newer ones we propose.  相似文献

A previous study suggested that small amounts of morphine are metabolically converted to hydromorphone. In the present study, morphine positive urine specimens obtained from a postmortem laboratory and a random urinalysis program were tested for morphine, codeine, hydromorphone, hydrocodone, oxymorphone, and oxycodone to assess the possibility that small amounts of hydromorphone are produced from the metabolism of morphine. The opioids were analyzed by gas chromatography-mass spectrometry as their respective trimethylsilyl derivatives following solid phase extraction. The limit of detection for hydromorphone was 5 ng/mL. A total of 73 morphine positive urine specimens were analyzed, with morphine concentrations ranging from 131 to 297,000 ng/mL. Hydromorphone was present at a concentration > or =5 ng/mL in 36 of these specimens at concentrations ranging from 0.02% to 12% of the morphine concentration. Hydrocodone was not detected in these specimens at the assay detection limit of 25 ng/mL. These results support earlier work suggesting that the detection of hydromorphone in urine specimens does not necessarily mean that exogenous hydromorphone or hydrocodone was used.  相似文献

The American myth of mobility suggests that educational attainment, as evidenced by some credential, is the road to achievement for everyone. This has never been entirely true, but recent trends suggest that the educational credential may increasingly limit as well as offer opportunity. Additional educational requirements have often been equated with increasing the “professionalism” of the public service, but they may also serve as a reason to keep out minorities or women now that non-meritorious discriminatory barriers have been eliminated by the courts. Examples from Mississippi and New York are cited. Although the courts have been vigilant in insisting that tests and other selection devices be validated, they have been much more tolerant of educational requirements, often failing to subject them to the stringent tests of job relatedness and validity. Even when a particular government unit is willing to lower credential barriers that cannot clearly be justified, it may be subject to pressures from other government units or associations, focusing on “improving” professional qualifications.  相似文献

Purpose

To compare theoretical explanations of the age-versatility curve including the hypotheses of: self-control theory stating that versatility is followed by specialization; taxonomic theory stating that adolescent-limited offenders are specialists and life-course offenders are versatile and orthogenetic theory stating that specialization and versatility are present in a large number of offender groups.

Methods

These explanations were tested with Israeli national population-based data on all first and subsequent juvenile offenders (n = 17,176) with 248,114 registered police contacts from 1996 to 2008.

Results

Semi-parametric group-based modeling identified two trajectory-groups that characterized the age-versatility curve of police contacts before first conviction. The trajectory-groups were labeled as versatility (n = 2,447; 14.2%), and specialization (n = 14,729; 85.8%). After controlling for 19 documented demographic, familial, and criminogenic risk factors, Cox regression showed that juvenile offenders in the versatility group were at increased risk of recidivism compared to offenders in the specialization group.

Conclusions

These results partially adhere with taxonomic theory than the remaining theories and indicate that assuming a trajectory of elevated pre-conviction versatility increases the risk of recidivism.  相似文献

We examine the dissent voting record of the Bank of England Monetary Policy Committee. Contrary to findings in the FOMC literature (for example Havrilesky and Schweitzer in The Political Economy of American Monetary Policy, pp. 197?C210, 1990; Chappell et al. in Q. J. Econ. 108(1):185?C218, 1993), the effects of members?? career backgrounds and the political channel of appointment on voting behavior are negligible, reflecting the distinct institutional constraints and incentives associated with UK monetary policy. Our findings also suggest that literature which characterizes voting behavior as being predominantly determined by members?? internal or external status is overly simplistic. This view is supported by econometric results appertaining to the introduction of member-specific fixed-effects, which account for possible unobserved heterogeneity.  相似文献
