Recent debates regarding the effectiveness of regulatory policymaking in the European Union (EU) focus on the merits of soft, non-binding forms of regulation between public and private actors. The emergence of less coercive forms of regulation is analyzed as a response to powerful functional pressures emanating from the complexity of regulatory issues, as well as the need to secure flexibility and adaptability of regulation to distinctive territorial economic, environmental, administrative, and social conditions. In this article we empirically assess the above normative claims regarding the effectiveness of soft regulation vis-à-vis uniformly binding legislation. We draw on an exploratory investigation of the application of the Integrated Pollution Prevention and Control Directive of the EU in four countries. Our study reveals that effectiveness in the application of soft policy instruments is largely contingent upon strong cognitive, material, and political capacities of both state regulators and industrial actors involved in regulatory policymaking. In the absence of those conditions, the application of soft, legally non-binding regulation may lead to adverse effects, such as non-compliance and the “hollowing out” of the systems of environmental permits to industry. In the medium term, such developments can undermine the normative authority of the EU. 相似文献

Industrialized economies in the EU depend heavily on imports of minerals. The extraction and parts of the transport and processing of these minerals take place in the Global South and often bear high human rights and environmental risks. A lack of traceability in mineral supply chains makes it particularly difficult to hold companies accountable for negative environmental and social impacts of their operations and those of their suppliers. This paper analyses three mineral supply chains (copper, platinum, and gold) in order to develop propositions about how supply chain-specific characteristics affect traceability and foreign corporate accountability (FCA) in mineral supply chains. The analytical framework focuses on three dimensions: geopolitical dynamics, industry characteristics, and private governance mechanisms. The authors argue that chain-specific characteristics may foster or thwart traceability and FCA in mineral supply chains and thus provides a novel contribution to the debate on traceability and accountability in mineral supply chains. 相似文献

Research on child‐related risk factors for filicide is scant. We investigated whether prior healthcare use for injury (including poisoning) influences filicide risk. Victims (0–14 years; n = 71) were identified in a national autopsy database for the years 1994–2012 and compared to matched, general population controls (n = 355). Healthcare use data were retrieved from a national patient registry. Risks were estimated using odds ratios (ORs) and 95% confidence intervals (CIs). For females, prior inpatient care for injury conferred a statistically significant sevenfold risk (OR = 6.67 [95% CI: 1.49–29.79]), and any prior injury‐related healthcare use conferred a statistically significant fourfold risk (OR = 3.57 [95% CI: 1.13–11.25]), of filicide victimization. No statistically significant risks were found for males. Healthcare personnel should be aware that children treated for injuries, especially females, may be at an elevated risk of filicide victimization. Nevertheless, the filicide base rate remains low, and parents may be stigmatized by unfounded alerts; thus, prudent reflection should precede reports to the authorities. 相似文献

Are victim and perpetrator blame attributions affected more by situational-specific variables or observers’ basic motives and personal beliefs? In three experiments, varying the scenario setting, the effects of victim and participant age, participant gender, sympathy for the victim, trust in the justice system, belief in a just world and acceptance of rape myths were investigated. In total, 877 Swedish adolescents and adults read scenarios reflecting common acquaintance rape situations. Victim age (18 or 31) was manipulated, but did not affect attributed blame. Effects of participant age and gender varied markedly across the three experiments. Sympathy for the victim and acceptance of rape myths were stronger predictors than belief in a just world. Consistently, blame attributions were found to be more affected by personal beliefs than situational-specific variables. 相似文献
