To accomplish the objectives and the outcomes of the New Partnership for Africa's Development (NEPAD), African leaders have agreed, among other things, to subject their countries to peer review through the use of a unique and innovative African Peer Review Mechanism (APRM). This paper analytically describes and assesses the APRM. It contends that peer review represents a sea of change in the thinking of African leaders as they seek to reverse the trend of lack of accountability, political authoritarianism, state failure, and corruption to embrace and consolidate democracy as well as effect sound and transparent economic management. It is further argued that peer review would provide a number of benefits to those countries that subject themselves to it and that, in turn, would have positive multiplier effects on Africa's development performance. 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

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

The effects of dose–death interval on the detection of acute fentanyl exposure in fresh and decomposed skeletal tissues (marrow and bone), by automated enzyme-linked immunosorbent assay (ELISA) are described. Rats (n = 14) were administered fentanyl acutely at a dose of 0 (n = 2) or 60 μg/kg (n = 12) by intraperitoneal injection, and euthanized within 20, 45, 135, or 225 min. Femora and tibiae were extracted from the fresh corpses and marrow was isolated from the femoral and tibial medullary cavities. The remains were then allowed to decompose outdoors to the point of complete skeletonization, and vertebrae, pelvi and miscellaneous (humeri and scapulae) were recovered for analysis. In all cases, bones were cleaned in alkaline solution and then ground into a fine powder. Marrow was homogenized in alkaline solution. Fentanyl was extracted from ground bone by methanolic extraction. Extracts were adjusted to pH 6 and analyzed by ELISA. Perimortem heart blood was also collected and diluted in phosphate buffer prior to screening by ELISA. The effect of tissue type on ELISA response was examined through determination of binary classification test sensitivity and the relative decrease in absorbance (%DA, drug-positive tissues vs. drug-free controls) in each tissue type. Overall, the %DA varied significantly between extracts from different skeletal tissues at a given dose–death interval, according to the general order of marrow > decomposed bone > fresh bone. Binary classification test sensitivity values for fentanyl in marrow, fresh epiphyseal (femoral and tibial) bone, fresh diaphyseal (femoral and tibial) bone, decomposed vertebrae, decomposed pelvic bone, and decomposed miscellaneous bone were 67–100%, 0–33%, 0–33%, 0–67%, 0–67% and 0–33%, respectively, over all dose–death intervals. Although group mean %DA values showed a strong negative correlation with dose–death interval in marrow, fresh epiphyseal bone, decomposed vertebrae, pelvic and miscellaneous bone (r = ?0.989, ?0.930, ?0.955, ?0.903, and ?0.974, respectively), the high variability in both fresh and decomposed bone precluded differentiation of the dose–death intervals based on %DA value alone. Overall, the results suggested that the type of skeletal tissue sampled may not be as important as the amount of residual marrow remaining in skeletonized remains. 相似文献

This study compares ex ante estimates of the direct costs of individual regulations to ex post assessments of the same regulations. For total costs the results support conventional wisdom, namely that the costs of regulations tend to be overestimated. This is true for 14 of the 28 rules in the data set discussed, while for only 3 rules were the ex ante estimates too low. For unit costs, however, the story is quite different. At least for EPA and OSHA rules, unit cost estimates are often accurate, and even when they are not, overestimation of abatement costs occurs about as often as underestimation. In contrast, for those rules that use economic incentives, unit costs are consistently overestimated. The difference between the total‐cost and the unit‐cost results is caused by frequent errors in estimates of the effects of individual rules, which suggests, in turn, that the rule's benefits may also be overestimated. The quantity errors are driven both by difficulties in determining the baseline and by incomplete compliance. In cases of unit‐cost overestimation, unanticipated technological innovation appears to be an important factor — especially for economic incentive rules, although procedural and methodological explanations may also apply. © 2000 by the Association for Public Policy and Management. 相似文献

One of the most common motifs surrounding sports, sports teams, and sports stars is “the scandal.” One typifying feature of mediated scandals is the ease with which they can be presented as, or massaged into, an unfolding narrative. Although some research has been conducted into the initial stages of these narratives, there is significantly less that focusses on the ways in which the “transgressor” can be rehabilitated in a separate but linked part of that overarching story. This article addresses that gap by analysing two television commercials that significantly assisted the Melbourne Storm rugby league franchise in encouraging and maintaining identification and, coterminously, overcoming disidentification with its membership. Furthermore, we contend that the Melbourne Storm purposively used rhetorical strategies to emphasise the socially desirable aspects of its identity to repair damage done to its organisational image. Using rhetorical analysis, the article explicates the various techniques through which this was accomplished. 相似文献
