The history of a particular policy office, located in the U.S. Department of the Interior, is reviewed from the standpoint of a long-time participant-observer. This office played an active part in the formation of federal policies with respect to the leasing of Outer Continental Shelf oil and gas, the leasing of federally owned coal, and the supply and distribution of federally controlled water in the west, but in many other areas the office was less involved. The article examines the factors that affected the level of office involvement and, more generally, the character of office interactions with the various parts of the Interior Department. The problems of sustaining long-term agency support for a policy office and other issues with respect to the practice of policy analysis in government are discussed.  相似文献

The use of temperature-based short-term postmortem interval (PMI) estimation methods can be useful to homicide investigators at the scene of a questionable death; however, a number of current PMI estimation techniques have high error rates such that they are of limited utility to law enforcement investigators and forensic professionals. These methods fail to control confounding errors present in individual data. An averages-based method of short term postmortem interval estimation was compared to eight other methods, and found to predict postmortem interval considerably more accurately, and for much longer periods of time.  相似文献

In a sample of female college students, dysphoric and intermittently dysphoric subjects, in comparison to nondysphoric subjects, were expected to perform more poorly on a game requiring eye-hand coordination. Actual performance showed no differences between these three groups. Following performance, relative to nondysphoric subjects, dysphoric and intermittently dysphoric subjects evaluated their performance more negatively. Results are discussed in terms of cognitive theories of depression and recent research. Implications for future research are suggested.  相似文献

This article addresses important developments in the field of medicine and the law during the last year and highlights some of the significant areas of law affecting health care providers that should be considered. Actions against health care providers may include challenges to peer review immunity, allegations concerning the practice of medicine across state lines without a license, and even accusations of wrongfully assisting a patient to commit suicide. These areas are addressed in turn by this article. Finally, antitrust developments over the last year are briefly addressed as an emerging area of concern for providers forming complex practice networks in today's health care arena.  相似文献

This study examines the issue of whether the relationship of fertility to measures of economic resources is different at lower income levels than at higher levels. Testing was done in a rural Philippine setting in 1978-79. 3 measures of economic resources were utilized -- income, quality of housing, and provision of schooling for children. The data were drawn from a survey of rural families residing in 5 muncipalities of Iloilo province, on Panay Island in the central Philippines. In the study design, villages (or barangays) were selected from the 5 municipalities to obtain equal numbers of 3 agricultural types -- upland, rainfed lowland, and irrigated lowland farms. Interviews were conducted during a 4-month period in late 1978 and early 1979. Completed interviews of 1077 married women were obtained from 1066 households in 46 villages. These women were under age 50. The number of children ever born was used as the measure of fertility. To derive household income for the families in the survey both farm production and nonfarm income were converted into Philippine pesos. For a measure of housing quality, an index was formed based on 7 household items which could be considered amenities for the family and on the reported construction materials for 5 parts of the dwelling. This sample of households in the rural villages of Iloilo Province exhibited evidence of a threshold in the relationship between housing quality and fertility and between per capita income and fertility. For those families with per capita income less than 200 pesos per year, there was a strong positive relationship between 2 of the economic resource measures and fertility. This threshold for families of very low income showed support for the presence of limiting factors other than contraception. When the contracepting women of low income were removed from the analysis, the slope below the threshold became steeper. The poor nutrition and poor health that are associated with very low income can result in lower fecundity, thus biologically or nonvolitionally limiting fertility from what it could be with conditions of good health and nutrition. Among the families with higher per capita income, there was a negative relationship between per capita income and fertility. Housing quality yielded the strongest evidence of the threshold effect. Education of the children was not related to fertility in this model. Study findings indicate that for about 1/3 of this rural population initial increases in their economic level or living standard could result in increasing fertility up to a threshold level.  相似文献

A feature of government departments is the continuous stream of policy issues which arise and require some response. Lindblom's Science of Muddling Through provides one way of dealing with this situation but has often been criticized as too limiting. Yet experience with more comprehensive approaches has not been encouraging. Research has been undertaken, with particular reference to health services, to develop another approach to planning and policy making; a key feature in this approach is that issues must be filtered so that those which require an analytical rather than an administrative approach can be identified and their relative importance decided. Thus, issues of major importance can be selected for detailed planning attention and the inevitably limited planning skills that are available used to best effect. This paper puts forward proposals for this process of selection; it describes a set of criteria for selection and demonstrates how these can be used in a procedure which is systematic yet retains political realism.  相似文献

The extent and nature of lawyers'participation in civic life probably has important effects on the character of the community's activity and its out-comes. Where and how lawyers participate in voluntary associations may influence the ability of those organizations to function within the larger structure of American institutions.
This paper compares findings from two surveys of Chicago lawyers, the first conducted in 1975 and the second in 1994-95. Contrary to some expectations, the available evidence does not suggest that community activities of lawyers decreased. Moreover, lawyers'energies in 1995 appear to have been devoted more often to socially concerned organizations, those with a reformist agenda, than had been the case in 1975. The types of organizations with the greatest increase in activity were religious and civic associations. A smaller percentage of the respondents held leadership positions in 1995 than in 1975, but, because of a doubling in the number of lawyers, the best estimate is that the bar's absolute level of contribution to community leadership did not change greatly.
In both 1975 and 1995, a hierarchy of social prestige appears to have influenced the pattern of lawyers'community activities. Lawyers who had higher incomes, were middle-aged, were Protestants, and who had attended elite law schools were more likely to be active or leaders in most kinds of organizations. In ethnic and fraternal organizations, however, the elites of the profession had relatively low rates of participation, while government lawyers, solo practitioners, and graduates of less prestigious law schools predominated. Status hierarchies within the broader community—as well as social differences in taste, preference, or "culture"—clearly penetrate the bar.  相似文献

The identification of forensically important blowflies of the genus Chrysomya (Diptera: Calliphoridae) may be hampered by their close morphological similarities, especially as immatures. In contrast to most previous studies, the utility of a nuclear rather than mitochondrial genetic marker was investigated to solve this problem. The second internal transcribed spacer (ITS2) of ribosomal DNA (rDNA) was amplified and sequenced from all nine Chrysomya species known from Australia. Difficulties encountered with direct sequencing of ITS2 for Chrysomya flavifrons necessitated cloning prior to sequencing for this species, which revealed a low level (0-0.23%) of intraindividual variation. Five restriction enzymes (DraI, BsaXI, BciVI, AseI and HinfI) were identified that were able to differentiate most members of the genus by polymerase chain reaction (PCR) restriction fragment length polymorphism (PCR-RFLP). The PCR-RFLP analysis revealed characteristic restriction profiles for all species except the closely related species pairs Chrysomya latifrons+Chrysomya semimetallica and Chrysomya incisuralis+Chrysomya rufifacies. Ch. incisuralis and Ch. rufifacies were able to be separated using the size differences resulting from amplification of the entire ITS region. The lack of intraspecific ITS2 sequence variation among eight Ch. incisuralis specimens was verified by the identical restriction profiles generated from these specimens. A DNA-based approach, such as PCR-RFLP, has the capacity to be useful for the identification of forensic entomological evidence in cases where morphological characters are unreliable.  相似文献
