As performance‐based contracting in social welfare services continues to expand, concerns about potential unintended effects are also growing. We analyze the incentive effects of high‐powered, performance‐based contracts and their implications for program outcomes using panel data on Dutch cohorts of unemployed and disabled workers that were assigned to private social welfare providers in 2002 to 2005. We employ a difference‐in‐differences design that takes advantage of the fact that contracts gradually moved from partial performance‐contingent pay to full (100 percent) performance‐contingent contracting schemes. We develop explicit measures of selection into the programs and find evidence of cream skimming and other gaming activities on the part of providers, but little impact of these activities on program outcomes. Moving to a system with contract payments fully contingent on performance appears to increase job placements, but not job duration, for more readily employable workers.  相似文献

Citizenship tests are arguably intended as moments of hailing, or interpellation, through which norms are internalized and citizen-subjects produced. We analyse the multiple political subjects revealed through migrants’ narratives of the citizenship test process, drawing on 158 interviews with migrants in Leicester and London who are at different stages in the UK citizenship test process. In dialogue with three counter-figures in the critical naturalization literature – the ‘neoliberal citizen’; the ‘anxious citizen’; and the ‘heroic citizen’ – we propose the figure of the ‘citizen-negotiator’, a socially situated actor who attempts to assert control over their life as they navigate the test process and state power. Through the focus on negotiation, we see migrants navigating a process of differentiation founded on pre-existing inequalities rather than a journey toward transformation.  相似文献

General media outlets are increasingly arguing that the looting of cultural heritage artifacts contributes to the funding of terrorist groups such as Islamic State of Iraq and Syria (ISIS). This article reexamines this claim in light of the political science literature on internal conflicts duration. While we do know that armed conflicts contribute to an increase of looting activities in the territories at war, it is still too early to generalize the ISIS case and conclude that these activities contribute to significantly funding armed non-state actors and to prolonging internal armed conflicts. However, establishing this link may add political weight to archeologists' and art historians' efforts to curb the international trafficking of looted objects.  相似文献

The authors describe a case of suicide in the workplace. A 45-year-old man employed by a fruit and vegetable packing company was found dead in a room containing a modified atmosphere for the packaging of fruits and vegetables. The rescue team measured the carbon monoxide (CO) concentration of the ambient air with a digital CO tester and found a level higher than 600 particles per million. Analysis of an arterial blood sample taken with an airtight syringe revealed the absence of CO but high levels of carbon dioxide (CO(2)). Autopsy revealed no significant injury and police investigators found a handwritten note of intent, describing a recent personal crisis. The authors concluded that the cause of death was suicide by asphyxiation secondary to CO(2) intoxication and notably oxygen (O(2)) depletion. This manner of suicide is rare and most cases previously described in the literature were accidental intoxications. To the best of our knowledge, this is the first case of suicide by CO(2) intoxication and O(2) depletion in a room with a modified atmosphere.  相似文献

The use of amphetamine and 'ecstasy' (MDMA) has increased exponentially in many European countries since the late nineties, leading to a rapid growth in the number of clinical and forensic analyses. Therefore, a rapid screening procedure for these substances in biological specimens has become an important part of routine toxicological analysis in forensic laboratories. The objective of this study was to evaluate the Cozart amphetamine enzyme-linked immunosorbent assay (ELISA) for the screening of plasma samples and oral fluid samples (collected with the Intercept device). Authentic plasma samples from drivers (n=360) were screened, using an 1:5-fold dilution. True positive, true negative, false positive and false negative results were determined relative to the in-house routine GC-MS analysis. Samples consisted of 144 amphetamine-only positives, 141MDMA/MDA-only positives, and 74 negatives when using the limit of quantitation as the cut-off level for confirmation (10 ng/mL). Using these results, receiver operating characteristic (ROC) curves were generated and optimal cut-off values for the screening assay were calculated. Analysis showed that the ELISA is able to predict the presence of either amphetamine or *MDMA/MDA (*MDMA as its metabolite MDA) in plasma samples with 98.3% sensitivity and 100% specificity at a cut-off value of 66.5 ng/mL d-amphetamine equivalents. A similar analysis was conducted on 216 oral fluid specimens collected from a controlled double blind study. Subjects received placebo or a high (100 mg) or low (75 mg) dose of MDMA. Oral fluid samples were collected at 1.5 and 5.5h after administration. Combined results of the analysis of the high and low dose oral fluid samples indicated a screening cut-off of 51 ng/mL d-amphetamine equivalents with both a sensitivity and specificity of 98.6% (using a LC-MS/MS confirmation cut-off of 10 ng/mL). In conclusion, these data indicate that the Cozart AMP EIA plates constitute a fast and accurate screening technique for the identification of amphetamine and MDMA/MDA positive plasma samples and oral fluid specimens (collected with Intercept. It should be emphasized that method validation should be performed for each type of biological matrix.  相似文献

Abstract. The authors consider two separate questions concerning the independence of Quebec: would Quebec improve its standard of living if it left the federation? and would political independence make it easier for Quebec to solve its economic problems? They argue that the first question, which is entangled in the ‘battle of regional economic accounts,’ cannot be answered satisfactorily and has drawn too much attention so far. So they focus on the second question, which they dissect into four sub-questions: 1/the options open to Quebec in the international economy; 2/structural adjustment and development policies; 3/employment stabilization policies; and 4/the organization of production and income distribution policy. The authors stress that the margins of latitude open to an independent Quebec would be rather narrow at the international level. But they conclude that, if the rigidities injected by the federal bureaucracy into the functioning of the federation and into the debate between levels of government persist, an independent Quebec could reap some net benefits in terms of economic development, employment stabilization, production organization and income distribution. Hence, the cost of political independence would be an increasing function of the capacity of Canadian federalism to display more flexibility in those matters in the future.  相似文献
