This study assessed work-related and driver-related factors in fatigue among Finnish heavy vehicle drivers. 683 professional drivers responded to a questionnaire, 27.8% of whom reported often feeling fatigue during their work shifts. Of the respondents, 27.5% reported having momentarily fallen asleep at the wheel while driving during the past year. Almost half (46.8%) of the fatigued drivers estimated the reasons for momentarily falling asleep were work-related. Long working shifts and short sleeps significantly increased the risk of momentarily falling asleep at the wheel. The risk of fatigue was the highest for the drivers who were unable to choose the time of their breaks.  相似文献

The well established effect of word frequency on adult's picture naming performance is now called into question. This is particularly true for variables which are correlated with frequency, as is the case of age of word acquisition. Since the work of [Carrol and White, 1973] there is growing agreement among researchers to confer an important role in lexical access to this variable. Indeed, it has been shown ( [Hodgson and Ellis, 1998]) that for normal English-speaking adults only the variables 'age-of-acquisition' and 'name agreement' are independent predictors of naming success among the various variables considered. However, when brain-damaged subjects with and without degenerative pathologies are studied, word frequency and word length as well as concept familiarity all give significant effects ( [Hirsh and Funnell, 1995]; [Lambon Ralph et al., 1998]; [Nickels and Howard, 1995]). Finally, it has been suggested that the production of specific error types may be related to such variables. According to [Nickels and Howard, 1994] the production of semantic errors is specifically affected by 'imageability' and in the recent study by [Kremin et al., 2001] 'age of acquisition' predicts (frank) word finding difficulties.  相似文献

Assessment centers (ACs) are popular selection devices in which assessees are assessed on several dimensions during different exercises. Surveys indicate that ACs vary with regard to the transparency of the targeted dimensions and that the number of transparent ACs has increased during recent years. Furthermore, research on this design feature has put conceptual arguments forward regarding the effects of transparency on criterion‐related validity, impression management, and fairness perceptions. This study is the first to examine these effects using supervisor‐rated job performance data as the criterion. We conducted simulated ACs with transparency as a between‐subjects factor. The sample consisted of part‐time employed participants who would soon be applying for a new job. In line with our hypothesis, results showed that ratings from an AC with nontransparent dimensions were more criterion valid than ratings from an AC with transparent dimensions. Concerning impression management, our results supported the hypothesis that transparency moderates the relationship between self‐promotion and job performance, such that self‐promotion in the nontransparent AC was more positively related to job performance than self‐promotion in the transparent AC. The data lent no support for the hypothesis that participants’ perceptions of their opportunity to perform are higher in the transparent AC.  相似文献

This study explored the parenting self‐efficacy of the parents of 18‐month‐old children in the context of Finnish maternity and child health clinics. This parenting self‐efficacy was observed in relation with the relational continuity of care and parents' experienced loneliness and depressive symptoms. The relational continuity of care was provided by a public health nurse in maternity and child health clinics. The participating parents were drawn from the STEPS study that is being carried out by the Institute for Child and Youth Research at the University of Turku. The results showed that relational continuity of care provided by the same public health nurse in the maternity and child health clinics was associated with mothers' higher emotional loneliness and with lower scores on three dimensions of parents' parenting self‐efficacy. Loneliness and depressive symptoms negatively influenced parents' parenting self‐efficacy – however, in the case where the family had experienced relational continuity of care, the parents' higher levels of depressive symptoms had not weakened their parenting self‐efficacy beliefs. These results are discussed in terms of organizing maternity and child health clinic services.  相似文献

In the self‐worth model, burnout is considered to be a syndrome of performance‐based self‐esteem (PBSE) and experiences of exhaustion. Studies have shown that PBSE and burnout indices such as Pines’ Burnout Measure (BM) are associated. Whether these variables have overlapping etiologies has however not been studied before. Genetic and environmental components of covariation between PBSE and exhaustion measured with Pines’ BM were examined in a bivariate Cholesky model using data from 14,875 monozygotic and dizygotic Swedish twins. Fifty‐two per cent of the phenotypic correlation (r = 0.41) between PBSE and Pines’ BM was explained by genetics and 48% by environmental factors. The findings of the present study strengthen the assumption that PBSE should be considered in the burnout process as proposed by the self‐worth conception of burnout. The present results extend our understanding of the link between this contingent self‐esteem construct and exhaustion and provide additional information about the underlying mechanisms in terms of genetics and environment. This finding corroborates the assumed syndrome view on burnout, while it also suggests an altered view of how the syndrome emerges and how it can be alleviated.  相似文献

In responding to Mathias Beck's thought-provoking article, it seems helpful to begin with an outline and comments on Beck's case as I understand it. For me, this overview throws up three problematic areas that I explore further under the headings of 1. examining the New Testament evidence, 2. sin as disobedience, and 3. obedience, grace, and freedom. Clearly, the author's thoughts in all their nuances are not always adequately accessible in translation. Nevertheless, I hope that I have grasped the main thread of his argument. If I am right in my interpretation then Beck still has work to do to clarify and make explicit what is not only barely implicit but what is obscured by his central theme: that obedience to God's will is the mainstay of our relationship to God.  相似文献

Preventive mental health work has for many years been a cornerstone in child psychiatric work in Sweden. Psykologverksamheten, a program at Psykiska Barn och Ungdomsvarden (PBU), is the out-patient child psychiatry unit in Stockholm County. The aim of the program is to promote infant mental health and to prevent children from becoming future patients at the psychiatric child and adolescent clinics. Located in the residential areas, the Maternal and Child Health (MCH) centers reach almost 100% of infant families and are the platform for the preventive work. The pediatric staff at the MCH centers have been encouraged to apply a psycho-social working model in which not only the pediatric but also the psychological needs of the families are considered. In regular case-consultations child psychologist have offered training and support to the medical staff. This has been bases on the theoretical assumption that if the MCH staff are better equipped in dealing with mental health issues, the support they give to infant families will improve and the referrals to the psychologist at the Psykologverksamheten will decrease. However, through the working alliance established between the MCH staff and the psychologist, the latter has become a professional “secure base,” making the MCH staff more sensitive and observant than earlier. Because the Swedish welfare system is at present undergoing changes due to Government economic restraints, the stress put on families has increased. The referrals to the psychologists have almost doubled. The paper discusses the qualitative development of the relationship between the Psykologverksamheten and the MCH staff, and, with reference to a clinical vignette, discusses the importance of not only supporting general preventive work but also of specifying early dyadic therapeutic interventions. © 1998 Michigan Association for Infant Mental Health  相似文献
