The study investigated the relationship between employees’ experience of performance management and work engagement. Participants were a convenience sample of employed adults (N=202; females=59%, middle management?=?48%, White?=?54%, tenure more than 9 years?=?48%) in an organisation in the vehicle and asset-based finance industry. They completed the Performance Management Questionnaire (PMQ) and Utrecht Work Engagement Scale (UWES). Multiple regression analysis was used to determine the proportion of variance of work engagement that is explained by employees’ experience of performance management. Results revealed that only empowerment significantly predicted work engagement. These findings suggest that when employees experience performance management as empowering, they are also likely to have higher levels of work engagement.  相似文献

ObjectivesThis study aimed to examine the effects of change in perceived teacher achievement goal emphasis in physical education (PE) on physical self-perceptions and self-esteem across the transition to secondary school.Design & methodsA longitudinal design was adopted with three time points, one at the end of primary school and two during the first year of secondary school. Participants (N = 491) were cross-classified by primary (N = 42) and secondary (N = 46) PE class in order to examine the association between perceived class-level teacher-emphasised goals and within-class student goals with self-beliefs.ResultsPersonal approach goals and class perceptions of teacher mastery approach goal promotion were all positively associated with ratings of co-ordination, sport competence, flexibility, and endurance in primary school. More favourable perceptions of coordination, sport competence, strength, flexibility, and endurance during the first year of secondary school were predicted by an increase in performance approach goal emphasis, whereas ratings of sport competence and flexibility were negatively associated with an increase in mastery approach goal emphasis.ConclusionsAlthough not entirely consonant with theoretical predictions, current findings suggest that teacher-emphasised performance approach goals in PE can promote development of several physical self-perceptions in the initial year of secondary school.  相似文献

ObjectiveThe present study examined to what extent off-field offside decision-making training transfers to real-life offside situations.Design/methodsEighteen Belgian assistant referees were included in the experiment. Ten assistant referees (i.e., training group) were exposed to a pre- and posttest and, in between, four off-field offside training sessions via a web-based training protocol. The remaining eight assistant referees participated in the control group and only completed the pre- and posttest. During both test sessions, which were conducted separately for each group, both an on- and off-field offside decision-making test was completed.ResultsFirst, an increase in response accuracy and a decrease in flag errors were observed for the training group from pre- to posttest in both the on- and off-field offside test. Second, only the training group improved in the recall and recognition accuracy of the position of the receiving attacker at the moment of the pass.ConclusionsThis study demonstrates that perceptual-cognitive skill training results in a positive and direct transfer to on-field offside decisions. Therefore, the structure and the content of the current training intervention mimics the perceptual difficulties of real-match situations and can help the assistant referees to mediate and enhance their offside decision-making skills, both on- and off-field.  相似文献

Limited health literacy is a pervasive and independent risk factor for poor health outcomes. Despite decades of reports exhibiting that the healthcare system is overly complex, unneeded complexity remains commonplace and endangers the lives of patients, especially those with limited health literacy. In this article, we define health literacy and describe the empirical evidence associating health literacy and poor health outcomes. We recast the issue of poor health literacy from within the ethical perspective of the least well-off and argue that poor health outcomes deriving from limited health literacy ought to be understood as a fundamental injustice of the healthcare system. We offer three proposals that attempt to rectify this injustice, including: universal precautions that presume limited health literacy for all healthcare users; expanded use of technology supported communication; and clinical incentives that account for limited health literacy.  相似文献

Abstract

Curriculum-based measurement (CBM) has evolved as a reliable and valid method for measuring and monitoring student performance in basic academic skills. While the efficacy of CBM for assessing reading skills is not in question, issues remain regarding whether or not a difference exists between CBM probes derived directly from the instructional curriculum and generic probes. The current study extends previous research comparing the utility of two types of CBM reading probe materials. Both types of probes were administered to 13 second grade students twice weekly for 5 weeks. No significant differences were found between the two probe types' measurement of performance or progress over time, which suggests that school psychologists and educational professionals can use generic or curriculum-dependent probes in curriculum-based measurement.  相似文献

ABSTRACT

It is estimated that there have been over 4,000 articles in the literature on the subject of attentional problems, addressing its etiology, epidemiology, assessment, diagnosis, and treatment. This article reviews recent and relevant literature with an eye toward functional conclusions and linkages between assessment and intervention. The article concludes by providing a problem-solving model that integrates parent or teachers' referral concerns, reasons for these concerns, assessment methods, and intervention strategies. In the end, four definitive conclusions are drawn, and the importance of multimodal strategies that collaboratively involve home, school, and community settings is emphasized.  相似文献

Abstract

This study extended the evaluation of frequent vs non-frequent prompts to support task performance with people with severe intellectual disability. Three participants were involved in the study. The data indicated that the frequent prompts strategy promoted higher levels of on-task behaviour and correct responding for 2 participants and on-task behaviour for 1 participant. The relation of these data with previous findings and their implications for daily occupation programmes for persons with severe developmental disabilities are discussed  相似文献

Abstract

De olika kontrollerade gruppstudier och okontrollerade fallstudier som finns publicerade rörande beteendeterapeutiska metoder vid ångestneuros presenters och evalueras. Studierna har uppenbara brister vad gäller presentation av patientmaterialet, mätmetoderna och tillämpningen av vissa behandlingsmetoder. Resultaten visar i allmänhet på relativt små och sällan kliniskt signifikanta förbättringar. Artikeln avslutas med rekommendationer för fortsatt forskning framför allt rörande andra behandlingsmetoder än de hittills prövade.  相似文献

This paper reviews the evidence‐based literature concerning the efficacy and effectiveness of cognitive behavior therapy (CBT), drug treatment and their combination for obsessive‐compulsive disorder (OCD). After a brief outline of the seminal studies, the state of the art is presented with reference to the consensual recommendations proposed in the last 10 years. Management of OCD rests on potent selective serotonin re‐uptake inhibitors and CBT, used separately, sequentially, or concurrently. A hierarchical model for clinical decision‐making is reported. With greater severity of OCD, it is recommended to add medications. However, the response rate is still too low in many patients, and some patients remain refractory to any kind of treatment. This stresses the importance of joint efforts of psychological and biological teams to develop new treatments.  相似文献

Fifty-three national level cyclists completed competitive rides under both laboratory and field conditions to investigate the relationship between pre-competition anxiety and performance. A total of 39 males and 14 females participated in the study, ranging in age from 19 to 26. The objectives of the study were to, (a) measure the relationship between state anxiety and performance, (b) investigate differences in the anxiety-performance relationship under laboratory versus field conditions, and (c) examine the effect of trait anxiety on the state anxiety-performance relationship. State anxiety was measured using the Competitive State Anxiety Inventory-2 (CSAI-2; Martens, Vealey, & Burton, 1990), and trait anxiety with the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, & Lushene, 1970). Results indicated that anxiety was strongly correlated with performance on the field test, but that the anxiety-performance relationship was weaker under laboratory conditions. Results also showed that trait anxiety interacted with the relationship, as low and high trait-anxious subjects had differential response patterns to pre-competition anxiety. The findings are discussed in terms of their relevance for both practitioners and researchers.  相似文献
