There is consistent evidence that older adults have difficulties in perceiving emotions. However, emotion perception measures to date have focused on one particular type of assessment: using standard photographs of facial expressions posing six basic emotions. We argue that it is important in future research to explore adult age differences in understanding more complex, social and blended emotions. Using stimuli which are dynamic records of the emotions expressed by people of all ages, and the use of genuine rather than posed emotions, would also improve the ecological validity of future research into age differences in emotion perception. Important questions remain about possible links between difficulties in perceiving emotional signals and the implications that this has for the everyday interpersonal functioning of older adults.  相似文献

The two aims of the study were (a) to determine when infants begin to use force intentionally to defend objects to which they might have a claim and (b) to examine the relationship between toddlers’ instrumental use of force and their tendencies to make possession claims. Infants’ and toddlers’ reactions to peers’ attempts to take their toys were assessed in three independent data sets in which the same observational coding system had been used (N = 200). To ensure that infants’ use of force was goal‐directed and not a simple physical reaction, we recorded infants’ reactions when peers picked up toys that the focal infants had just put down, or were nearby or in the focal infants’ mothers’ laps. The use of force in response to peers’ taking over toys was evident before the first birthday, but more common thereafter, although only a minority of children in each sample used force. Analysis of a combined data set revealed that force was deployed more often by 2‐year‐olds than younger infants, and was significantly associated with verbal references to people’s possession of objects. These observations show that toddlers do deploy force intentionally to defend their possessions.  相似文献

The requirement for social work students to undergo assessed preparation prior to undertaking their first practice placement raises key questions about the type of knowledge and experience that is needed for those at the start of their training. This paper shows the need for social work educators to become re‐engaged in debates about the practice–theory relationship and to explore what is meant by an incremental approach to learning. A Preparation for Practice Learning module which was delivered to a cohort of Level 1 undergraduate social work students at a London university is described and evaluated. The paper highlights the key themes which emerged from the evaluation; these include the importance of work shadowing, observational learning and the centrality of critical reflection in aiding students' personal and professional learning. A discussion of its effectiveness in preparing students for their first practice learning experience follows. It concludes by recommending how students' learning in relation to the nature of social work and the skills required to undertake the role effectively might be addressed within the curriculum. Finally, a Preparation for Practice Learning model based on these findings is proposed.  相似文献

How do workers understand pay inequality? Every organizational field has a taken‐for‐granted compensation system that shapes understandings of rewards. Using data from 76 Wall Street professionals, I analyze how individuals interpret, understand, and justify inequality in a performance‐based reward system where pay is supposed to be based on merit. A majority of securities workers believed that the performance‐based pay system produced equitable rewards. But a substantial minority challenged the procedural and/or distributive justice of this pay system, producing counterinstitutional accounts. These accounts took three general forms: accounts of arbitrariness, accounts of misinformation, and accounts of discrimination. All of these counterinstitutional accounts pointed to nonmerit influences on bonuses. I argue that these challenges might undermine the legitimacy of the pay system, but most men and women who challenged the system exited their firms or the industry, so that their challenges did little to destabilize Wall Street's pay practices. Wall Street appears to maintain its legitimacy in part through the self‐selection of dissenters out of the system.  相似文献

This paper analyses the effects of government-sponsored attempts to change the way that the NHS, one of the largest employers in Europe, is managed. The theoretical issues raised relate to the concept of transformational change and attempts at public-sector restructuring, which set the context for the presentation of data. The empirical research, carried out over three years, examines the changes since the most recent reforms (the NHS and Community Care Act 1990).
The research considers the extent of organizational change which can be seen as the outcome of these reforms in relation to: a multiple and inter-related change agenda; the creation of new forms of organization; the creation of new roles; the reconfiguration of power relations; and the creation of a new culture, ideology and organizational meaning. These are presented as the key variables which could indicate whether transformational, rather than incremental, change has occurred. The focus of this analysis is at local board level.
This article concludes that earlier analyses of the limited success of administrative reform are no longer the case. Our analysis of the key variables suggests that what is occurring at least at local board level goes beyond incremental change and may represent the beginnings of an 'organizational transformation'. This contains unintended as well as intended elements as an unanticipated 'hybrid' form of management may be emerging.  相似文献

This article considers recent innovations and challenges withrespect to the evaluation of children’s services interventions.It sets out a method for designing and evaluating services thatis based on research evidence gathered on individual cases andthat permits revision of those services in the light of emergingresults. It starts by describing briefly different ways of identifyinga discrete group of children with similar needs. It then outlinesapproaches to ensuring that an intervention for those childrenis underpinned by theory and research evidence–includingthe idea of ‘logic modelling’–before discussingthe importance of capturing accurately how well the interventionis implemented. Experimental and non-experimental methods ofassessing an intervention’s effectiveness are considered,with particular emphasis on techniques for enhancing the causalinference that can be drawn from studies and the importanceof matching method and purpose. The article also demonstrateshow the principles and methods used in relation to evaluatingservices for groups can be applied in clinical work with individualcases, and identifies the benefits of this general approachto evaluation over and above the information that it provideson what works.  相似文献

The volume of research on terrorism has increased since the events of September 11, 2001. However, efforts to develop a contextualized model incorporating cognitive, social-contextual, and affective factors as predictors of individual responses to this threat have been limited. Therefore, the aim of this study was to evaluate a series of hypotheses drawn from such a model that was generated from a series of interviews with members of the Canadian public. Data of a national survey on perceived chemical, biological, radiological, nuclear, and explosives (CBRNE) terrorism threat and preparedness were analyzed. Results demonstrated that worry and behavioral responses to terrorism, such as individual preparedness, information seeking, and avoidance behaviors, were each a function of cognitive and social-contextual factors. As an affective response, worry about terrorism independently contributed to the prediction of behavioral responses above and beyond cognitive and social-contextual factors, and partially mediated the relationships of some of these factors with behavioral responses. Perceived coping efficacy emerged as the cognitive factor associated with the most favorable response to terrorism. Hence, findings highlight the importance of fostering a sense of coping efficacy to the effectiveness of strategies aimed at improving individual preparedness for terrorism.  相似文献

Intention‐to‐treat (ITT) analysis is widely used to establish efficacy in randomized clinical trials. However, in a long‐term outcomes study where non‐adherence to study drug is substantial, the on‐treatment effect of the study drug may be underestimated using the ITT analysis. The analyses presented herein are from the EVOLVE trial, a double‐blind, placebo‐controlled, event‐driven cardiovascular outcomes study conducted to assess whether a treatment regimen including cinacalcet compared with placebo in addition to other conventional therapies reduces the risk of mortality and major cardiovascular events in patients receiving hemodialysis with secondary hyperparathyroidism. Pre‐specified sensitivity analyses were performed to assess the impact of non‐adherence on the estimated effect of cinacalcet. These analyses included lag‐censoring, inverse probability of censoring weights (IPCW), rank preserving structural failure time model (RPSFTM) and iterative parameter estimation (IPE). The relative hazard (cinacalcet versus placebo) of mortality and major cardiovascular events was 0.93 (95% confidence interval 0.85, 1.02) using the ITT analysis; 0.85 (0.76, 0.95) using lag‐censoring analysis; 0.81 (0.70, 0.92) using IPCW; 0.85 (0.66, 1.04) using RPSFTM and 0.85 (0.75, 0.96) using IPE. These analyses, while not providing definitive evidence, suggest that the intervention may have an effect while subjects are receiving treatment. The ITT method remains the established method to evaluate efficacy of a new treatment; however, additional analyses should be considered to assess the on‐treatment effect when substantial non‐adherence to study drug is expected or observed.
