The employee assistance programme (EAP) is a benefit increasingly provided by UK employers that claims to reduce the effects of 'stress' on individuals and organisations, provide a 'management tool' to improve workplace performance and productivity, and respond to critical incidents. Although the marketing literature describes services as workplace-based counselling, there is evidence to suggest what they actually offer is consultation, assessment, referral and short-term treatment to clients experiencing a wide range of serious psychological and mental health difficulties. This article describes EAPs, their history, development and operation, and reviews the evidence to support their claims for effectiveness. Because employee distress is often the result of an interaction between organisational and individual factors, the role and claims of EAPs as organisational interventions are also critically examined.  相似文献

A non-monotonic logic, the Logic of Plausible Reasoning (LPR), capable of coping with the demands of what we call complex reasoning, is introduced. It is argued that creative complex reasoning is the way of reasoning required in many instances of scientific thought, professional practice and common life decision taking. For managing the simultaneous consideration of multiple scenarios inherent in these activities, two new modalities, weak and strong plausibility, are introduced as part of the Logic of Plausible Deduction (LPD), a deductive logic specially designed to serve as the monotonic support for LPR. Axiomatics and semantics for LPD, together with a completeness proof, are provided. Once LPD has been given, LPR may be defined via a concept of extension over LPD. Although the construction of LPR extensions is first presented in standard style, for the sake of comparison with existing non-monotonic formalisms, alternative more elegant and intuitive ways for constructing non-monotonic LPR extensions are also given and proofs of their equivalence are presented.  相似文献

The need for cultural competence and the need for evidence-based practice in mental health services are major issues in contemporary discourse, especially in the psychological treatment of people of color. Although these 2 paradigms are complementary in nature, there is little cross-fertilization in the psychological literature. The present article illustrates the complementary nature of these 2 paradigms. A main point of convergence is related to the development of culturally adapted interventions in the move from efficacy research to effectiveness studies. The implications of cultural adaptations of empirically supported treatments for mental health services in terms of research and practice with ethnic/racial minority populations are discussed.  相似文献

Past research has inconsistently distinguished the neural substrates of various types of working memory. Task design and individual performance differences are known to alter patterns of brain response during working-memory tasks. These task and individual differences may have produced discrepancies in imaging findings. This study of 50 healthy adults (M(age) = 19.6 yr., SD = .8) examined performance during various parametric manipulations of a verbal and spatial n-back working-memory task. Performance systematically dissociated on the basis of working-memory load, working memory type, and stimulus difficulty, with participants having greater accuracy but slower response time during conditions requiring verbal versus spatial working memory. These findings hold implications for cognitive and neuroimaging studies of verbal and spatial working memory and highlight the importance of considering both task design and individual behavior.  相似文献

Attitudes toward suicide among Chinese people in Hong Kong   总被引:1,自引:0,他引:1  
Since suicide in Chinese people exhibits certain distinctive characteristics, it is important to develop indigenous measures to assess Chinese attitudes toward suicide that may be used to inform suicide reduction programs. Combining qualitative and quantitative methods, we developed a Hong Kong version of the Chinese Attitude toward Suicide Questionnaire (CASQ-HK) which assesses attitudes toward suicide, suicidal inclination under 12 hypothetical scenarios, and prior suicidal experience. A convenience sample of 1,226 people completed the self-report questionnaire. In keeping with Chinese tradition, respondents revealed both tolerant and condemning attitudes that varied with their sociodemographic characteristics. Generally, they were not strongly inclined to consider suicide in the presence of difficult scenarios. Female gender, older age, and the presence of suicidal ideation were associated with more contemplation of suicide.  相似文献

Lexical decisions to high- and low-arousal negative words and to low-arousal neutral and positive words were examined in an event-related potentials (ERP) study. Reaction times to positive and high-arousal negative words were shorter than those to neutral (low-arousal) words, whereas those to low-arousal negative words were longer. A similar pattern was observed in an early time window of the ERP response: Both positive and high-arousal negative words elicited greater negative potentials in a time frame of 80 to 120 msec after stimulus onset. This result suggests that arousal has a differential impact on early lexical processing of positive and negative words. Source localization in the relevant time frame revealed that the arousal effect in negative words is likely to be localized in a left occipito-temporal region including the middle temporal and fusiform gyri. The ERP arousal effect appears to result from early lexico-semantic processing in high-arousal negative words.  相似文献

The purpose of the present study was to examine the nature of auditory representations by manipulating the semantic and physical relationships between auditory objects. On each trial, listeners heard a group of four simultaneous sounds for 1 sec, followed by 350 msec of noise, and then either the same sounds or three of the same plus a new one. Listeners completed a change-detection task and an object-encoding task. For change detection, listeners made a same-different judgment for the two groups of sounds. Object encoding was measured by presenting probe sounds that either were or were not present in the two groups. In Experiments 1 and 3, changing the target to an object that was acoustically different from but semantically the same as the original target resulted in more errors on both tasks than when the target changed to an acoustically and semantically different object. In Experiment 2, comparison of semantic and acoustic effects demonstrated that acoustics provide a weaker cue than semantics for both change detection and object encoding. The results suggest that listeners rely more on semantic information than on physical detail.)  相似文献
