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

The article explores the impact of Conservative governments since 1979 on business representation. It concentrates on the trade association—the most common form of business organization in the UK but one which has been largely neglected in the discussion of business representation. The results of a major survey of trade associations conducted in 1994 are reported and their significance assessed in the light of three general propositions about the direction of business representation since 1979. 相似文献

We show that Brazilian voters strongly sanction malfeasant mayors when presented with hypothetical scenarios but take no action when given the same information about their own mayor. Partnering with the State Accounts Court of Pernambuco, we conducted a field experiment during the 2016 municipal elections in which the treatment group received information about official wrongdoing by their mayor. The treatment has no effect on self‐reported voting behavior after the election, yet when informing about malfeasance in the context of a vignette experiment, we are able to replicate the strong negative effect found in prior studies. We argue that voters' behavior in the abstract reflects the comparatively strong norm against corruption in Brazil. Yet on Election Day, their behavior is constrained by factors such as attitudes toward local political dynasties and the greater salience of more pressing concerns like employment and health services. 相似文献

We evaluate the cost‐effectiveness of two early childhood interventions that use instructional coaching and parent coaching as levers for improvement. The study design allows us to compare the individual effects of each intervention as well as their combined effect on student outcomes. We find that teachers receiving instructional coaching improve their use of evidence‐based instructional practices, while families receiving parent coaching show increases in numerous responsive parenting behaviors associated with positive child outcomes. Both interventions demonstrate positive impacts on students, but only parent coaching shows statistically significant effects across a range of student outcomes. Instructional coaching alone is substantially less costly and may therefore be the most cost‐effective of the three treatment conditions; however, small sample sizes limit our ability to reach definitive conclusions. Policy simulations suggest that implementing these interventions could raise the overall cost‐effectiveness of Head Start by at least 16 percent. 相似文献
