This study considers numerous non-budgetary measures of policy activity (called functional actions) that are conducted by agencies as they seek to implement their programs. Relationships found in earlier research among maturity, coalitions, and budgetary variables with the functional actions of agencies are extended here through a subsample test of the data and through the utilization of functional actions as independent as well as dependent variables. These functional actions are considered important because they directly affect the lives of citizens, seem manipulable by agencies, and represent a crucial first step in evaluating both the governmental and societal impact of agency programs. Data for eight federal agencies from fiscal years 1960 through 1971 were usedincorporating percentages and simple bivariate correlation coefficients. While the findings remain tentative,numerous implications are suggested for agency behavior and for the empirical study of public policy. 相似文献

As the result of a previous study many laboratories have used XAM neutral medium-improved white mounting medium in textile fibre examination for more than 20 years. Due to European Directive 98/79/EC, XAM is no longer available and an alternative needed to be found. A list of desirable properties was formulated and a number of mounting media were tested against this. Entellan New was identified as the best mounting medium, and performed similarly to XAM in all aspects. 相似文献

This article outlines Chinese strategic nuclear forces and the Chinese philosophical approach to nuclear security. It then focuses on the domestic conditions in China which could precipitate vulnerabilities to its nuclear forces. From information about internal security conditions in China, specific internal threats to Chinese nuclear security will be derived. Based on these threats, several outsider and insider scenarios will be outlined involving a variety of terrorist or terrorist related behaviors. These notional scenarios will include everything from overrun or attack, to diversion, to cyber terrorism, to sabotage. The article will then cover what these scenarios and the possible Chinese reaction to them may mean for the security, military and diplomatic strategies of the United States. 相似文献

Changes in the age structure are shown to have a limited impact on aggregate crime rates. Even the dramatic transformation of the age distribution accompanying the baby boom shifted crime rates by no more than 1 % per year. Projected changes in the age distribution between 1995 and 2010 will lead to slight declines in per capita crime rates. These results are at odds with recent predictions of an impending demographically driven crime wave. Such predictions have focused exclusively on a rise in juvenile crime and ignored the offsetting decreases among adults. 相似文献

The diagnosis of posttraumatic stress disorder (PTSD) sometimes is raised in compensation claims, in tort settings, and in other medical–legal settings. Accordingly, health-care and legal professionals working in these areas need to be familiar with the current findings and controversies concerning the disorder. The purpose of this article is twofold. First, we review the most important findings concerning the clinical features, etiology, and treatment of PTSD. Second, we examine six major controversies concerning the disorder that are relevant to psychologists and other medical–legal practitioners: (a) the issue of what qualifies as a traumatic stressor, (b) the question of whether traumatic stress causes brain damage, (c) the validity of the concept of delayed-onset PTSD, (d) the recovered memory controversy, (e) the question of whether PTSD can arise when the person has no memory of the trauma (e.g., due to concussion), and (f) issues concerning PTSD malingering. Throughout this article we offer recommendations for psychological and other medical–legal practice in relation to the evaluation of PTSD claims. 相似文献

Fifty-eight garments were taped and searched for mid to dark blue wool fibres. These were then removed from the tapings, mounted on slides and examined using a high-power microscope (400x). A total of 2,740 blue wool fibres were identified and visible range microspectrophotometry (MSP) was performed on them. Three hundred independent blue wool populations were identified on 56 of the 58 garments searched. The lack of control fibres meant the spectral range of each population was unknown. The number of populations may have been underestimated by grouping together the fibres that had broad single peaks and a lack of distinguishing features in the spectra. Although blue wool is considered to be a common fibre type, 300 unique spectral shapes were identified by the use of microspectrophotometry alone. This demonstrates that the dyes used in the dyeing of blue wool are variable. Showing that many different populations of blue wool occur on a range of garments should ensure that the forensic scientist does not underestimate or understate the strength of evidence in cases where blue wool is found. Hopefully this work will enlighten scientists and enable them to also assess the true value of their findings when other commonly occurring fibres are encountered. 相似文献
