Since the rise of HIV/AIDS in Sub-Saharan Africa, there has been a massive promotion of condom use. Unfortunately, this promotion has not always been accompanied with instructions for safe use. In this case report, we describe a small child who aspirated a condom and subsequently died.  相似文献

Private organizations play a growing role in governing global issues alongside traditional public actors such as states, international organizations, and subnational governments. What do we know about how private authority and public policy interact? What are the implications of answering this question for understanding support for, and effects of, policy development generally? The purpose of this article is to reflect on these questions by introducing, and reviewing, a special issue that challenges explicit claims, and implicit methodologies, that treat private and public governance realms as distinct and/or static. We do so by advancing a theoretical and conceptual framework with which to explore how the contributions to this special issue enhance an understanding about governance interactions across a range of empirical, sectoral, and regional domains. We specifically introduce the concept of governance spheres to capture the proliferation of issue domains denoted by highly fluid interactions across public and private governance boundaries.  相似文献

During the 6th Conference of Parties (COP-6) in The Hague, the Netherlands, November 2000, crucial progress on a number of outstanding issues related to the Kyoto Protocol will have to be made to open the way for its early ratification, if not to save it from complete failure. Given the present lack of internal US political support for the Kyoto Protocol, the EU may play a pivotal role in making the Kyoto Protocol agreement a reality even without initial ratification of the US, if its able to provide sufficient leadership. In this overview article we discuss the main issues under negotiation, the problems of finding agreement and opportunities for the EU to catalyse a compromise agreement at COP-6, building on key scientific papers as included in this issue and discussions at the European Forum on Integrated Environmental Assessment Climate Policy Workshop in Amsterdam. Key elements are the inclusion of sinks, the use of the Kyoto Protocol mechanisms as a supplement to domestic action and the international compliance system. Domestic implementation of climate policy is a major factor for the EU's credibility.  相似文献

Interpreting a myocardial inflammation as causal, contributory or as of no significance at all in the cause of death can be challenging, especially in cases where other pathologic and/or medico-legal findings are also present. To further evaluate the significance of myocardial inflammation as a cause of death we performed a retrospective cohort study of forensic and clinical autopsy cases. We revised the spectrum of histological inflammatory parameters in the myocardium of 79 adult autopsy cases and related these to the reported cause of death. Myocardial slides were reviewed for the distribution and intensity of inflammatory cell infiltrations, the predominant inflammatory cell type, and the presence of inflammation-associated myocyte injury, fibrosis, edema and hemorrhage. Next, the cases were divided over three groups, based on the reported cause of death. Group 1 (n = 27) consisted of all individuals with an obvious unnatural cause of death. Group 2 (n = 29) included all individuals in which myocarditis was interpreted to be one out of more possible causes of death. Group 3 (n = 23) consisted of all individuals in which myocarditis was reported to be the only significant finding at autopsy, and no other cause of death was found. Systematic application of our histological parameters showed that only a diffuse increase of inflammatory cells could discriminate between an incidental presence of inflammation (Group 1) or a potentially significant one (Groups 2 and 3). No other histological parameter showed significant differences between the groups. Our results suggest that generally used histological parameters are often insufficient to differentiate an incidental myocarditis from a (potentially) significant one.  相似文献

The rule-of-law-backsliding in some Member States has subverted not only one of the EU fundamental values but also trust among national authorities when implementing European Arrest Warrants (EAW). However, when evaluating the execution of EAWs issued by countries experiencing rule-of-law crises, the Court of Justice of the EU (CJEU) sought to preserve judicial cooperation and imposed a rather “top-down” view on mutual trust among Member States. This approach seemingly disregards the (dis)trust which has emerged in the EU due to rule-of-law-backsliding and fails to acknowledge the psycho-sociological nature of trust. Drawing on the trust literature, the paper offers novel conceptual elements to rethink mutual trust in the EAW framework. Notably, it critically assesses some of the gaps in the CJEU's interpretation of mutual trust and advances suggestions to embed empirical considerations in the conceptualisation of this principle to bridge the gap between trust in practice and in principle.  相似文献

As evidence mounts about the positive effects of autonomous motivation such as public service motivation, there is a growing case for public organizations to design reforms to better support public employees’ inherent desire to help others. But how feasible is this in reality? Most experimental evidence on autonomous motivation stems from interventions at the individual level, possibly exaggerating what government reforms can achieve in reality. We present a longitudinal study that analyses a three-year trial in Danish hospitals in which incentives and autonomy were changed to encourage autonomous motivation. This set-up offers a rare opportunity to observe the potential malleability of intrinsic, public service, user and external motivation. The results show little observable change in motivation due to the reform. We explore the practical difficulties of translating evidence about motivation into reforms given implementation challenges, contextual factors and a recognition that motivation might be less malleable than implied by research.  相似文献

The claim that Public Service Motivation (PSM) is an antecedent of prosocial behaviour has often been empirically tested and supported. However, closer inspection of this literature reveals large disparities in relating the two constructs. One reason that could explain such differences is that the relationship between PSM and prosocial behaviours has been primarily tested using self-reported cross-sectional, single-rater and same-survey data. While all of these are widely used methodological approaches in social sciences, they are also susceptible to potential biases. We conduct two comparative studies to re-examine this relationship. Study 1 utilizes self-reported cross-sectional, single-rater and same-survey data linking PSM and prosocial behaviour, revealing a positive relationship with PSM's Compassion dimension. Study 2 involves observing actual prosocial behaviour in a real-life setting. Then, the correlation between PSM and prosocial behaviour disappears. We conclude by discussing the possible reasons that could lead to the differences found across the two studies.  相似文献

ABSTRACT

This article explores the emergence of Karl Marx’s concept of history over the period 1841 to 1846. Whereas in Marx’s view the productive forces shaped human history, it is argued in this article that Marx believed the productive forces in their turn were fuelled by psychological drives; in effect, Marx made the passions the deepest motive force of history. ‘Historical materialism’ as it crystallized in those early years was a theory of materialized subjectivity. Marx’s comments on various Antique and Modern philosophies of nature evince that he discerned important parallels between the developmental processes of human history and of nature. If Marx traced the dynamism of the productive forces to the human passions, he was adhering to an essentially Romanticist ontology of self-creative, impassioned nature.  相似文献

ABSTRACT

The current study had three aims: (1) to explore whether there is over-time change in adolescent delinquency and negativity in the parent–adolescent, sibling and marital relationships during adolescence; (2) to examine the interactions of negativity across subsystems; and (3) to examine whether levels and changes in adolescent delinquency are predicted by levels and changes in negativity in all family subsystems. Data of 497 families participating in the RADAR-young study were used. Ratings of all family members were used to measure negativity in family relationships, and adolescent self-report was used for delinquency. Multivariate latent growth curve models showed over-time increases in mother-adolescent negativity and over-time decreases in sibling negativity, as well as significant individual differences in these changes. Second, evidence for both social contagion and compensatory processes in family negativity was found. Third, initial levels of parent–adolescent negativity were related to initial levels but not over-time changes of adolescent delinquency, whereas initial levels of sibling negativity were related to over-time changes but not initial levels of adolescent delinquency. Finally, increases in parent–adolescent negativity were related to faster increases in adolescent delinquency, and decreases in sibling negativity were related to slower increases in adolescent delinquency. Implications of these results are discussed.  相似文献
