One challenge for government administration is to reap the benefits of specialization while minimizing its negative side effects. In this article, I study the factors that motivate departments to contribute to the joint formulation of public policies. I derive testable hypotheses that discriminate between two competing motivations for interdepartmental cooperation. If department managers are concerned for the quality of public policy, I expect cooperation to be efficient. If, by contrast, departments compete for administrative turf, I expect cooperation to be inefficient and resources to be wasted. I test those hypotheses by studying all policy proposals adopted and published by the European Commission between 2015 and 2017—a total of approximately 4,000 cases. For politically salient proposals, I find that departments are more likely to contribute if they expect competing departments to become active, too. By contrast, the preparation of technical, non-salient proposals is left to the most specialized departments. Overall, my findings suggest that interdepartmental cooperation in the European Commission is significantly motivated by DGs' competition for administrative turf. 相似文献

正Fashion is a way of life.Although it may be unique and based on cultural inclination,it is also a global language understood by all.Fashion can manifest itself in clothing,accessories,makeup,footwear and body posture,making it a diverse industry that is always relevant and dynamic.Being a fashion designer is all about telling a particular story through art,which I have been actively involved in for the past 10 years. 相似文献

Politicians who support higher public spending in the hope of gaining the support of transfer recipients, such as the aged, the unemployed, and those on welfare, have no reason to believe that the strategy will succeed; according to the evidence reviewed here, transfer recipients do not vote much differently on such issues from other voters. State and local employees have shown a clear preference for higher public spending, but their numbers are limited and the relative strength of their preference weak, so that their impact on voting outcomes has been only marginal. 相似文献

Use of proximal femur shape to determine ancestry has appeal, but its validity is problematic because of unaddressed issues associated with skeletal plasticity, within- and between-population variation, sample selection, and interobserver error. In this paper, I inspect within- and between-group variation in proximal femur shape using five groups (American Blacks, American Whites, Hispanics, Native Americans, and Polynesians), and examine the affect of three environmental variables (subsistence strategy, physical terrain, and geographical region). Finally. I consider the validity of using the proximal femur to assess ancestry. The results show that there is significant within-group variation in proximal femur shape. Among Native Americans, both geographical location and subsistence strategy have a significant affect on proximal femur shape. Nevertheless, this study generally verifies the assertion that the proximal femur can be used reliably to distinguish Native Americans from American Blacks and Whites, but its precision may be reduced in some geographical regions. 相似文献
