Background: Vigilant coping is characterized by a deep processing of threat-related information. In many cases, vigilant coping increases stress symptoms, whereas avoidant coping decreases negative affect. However, vigilance may be beneficial when stress-eliciting situations involve a risk of injury or escalation as is usually the case in police operations. Design: We investigated the roles of vigilance and cognitive avoidance in police operations in a cross-sectional survey. Methods: The participants were 137 students (104?men, Mage?=?28.54, SD?=?8.04) from the Federal University of Applied Administrative Sciences; 76 of them were already police officers (work experience: M?=?12.59?years), and 61 were police officer candidates who had completed a 3- to 6-month police internship. Participants completed a paper-and-pencil survey and reported their operational stress, dispositional vigilance and cognitive avoidance in police operations, and stress symptoms. Results: We found that vigilance was negatively associated with stress symptoms and moderated the relationship between operational stress and stress symptoms. Cognitive avoidance, on the other hand, just missed the level of statistical significance in our test of whether it was positively associated with stress symptoms. Conclusions: Our findings demonstrate that vigilance may protect against the negative consequences of stress in police operations. 相似文献

Currently, the majority of investigations of linguistic manifestations of neurodegenerative disorders such as Alzheimer’s
disease are conducted based on manual linguistic analysis. Grammatical complexity is one of the language use characteristics
sensitive to the effects of Alzheimer’s disease and is difficult to operationalize and measure using manual approaches. In
the current study, we demonstrate the application of computational linguistic methods to automate the analysis of grammatical
complexity. We implemented the Computerized Linguistic Analysis System (CLAS) based on the Stanford syntactic parser (Klein
and Manning, Pattern Recognition, 38(9), 1407–1419, 2005) for longitudinal analysis of changes in syntactic complexity in language affected by neurodegenerative disorders. We manually
validated CLAS scoring and used it to analyze writings of Iris Murdoch, a renowned Irish author diagnosed with Alzheimer’s
disease. We found clear patterns of decline in grammatical complexity consistent with previous analyses of Murdoch’s writing
conducted by Garrard, Maloney, Hodges, and Patterson (Brain, 128(250–260, 2005). CLAS is a fully automated system that may be used to derive objective and reproducible measures of syntactic complexity
in language production and can be particularly useful in longitudinal studies with large volumes of language samples. 相似文献

Our intention in the following article is to bring forth connections with spiritual resources in teaching and supervision. We construct this focus within a collaborative learning approach. Methods and techniques used include curiosity, reflexivity inquiry, deconstruction, outsider witness practices and re‐authoring conversations. We evaluate how the dialogue has transformed our abilities to relate to spirituality. 相似文献

Acquired epileptiform aphasia (AEA) is characterized by deterioration in language in childhood associated with seizures or epileptiform electroencephalographic abnormalities. Despite an extensive literature, discrepancies and contradictions surround its definition and nosological boundaries. This paper reviews current conceptions of AEA and highlights variations in the aphasic disturbance, age of onset, epileptiform EEG abnormalities, temporal course, and long-term outcome. We suggest that AEA, rather than being a discrete entity, is comprised of multiple variants that have in common the features of language regression and epileptiform changes on EEG. Viewed this way, we argue that AEA can be conceptualized on a spectrum with other epileptiform neurocognitive disorders that may share pathophysiological features. The implications of this viewpoint are discussed, with emphasis on parallels between the AEA variants and regressive autistic spectrum disorders. 相似文献

Attitudes, beliefs, and orientations of 253 managers toward performance appraisal, along with the personality dimension conscientiousness, were used to predict rating behavior (i.e., mean ratings and measures of performance dimensions discrimination and ratee discrimination). As predicted, relationships between rater attitudes and rating behavior were moderated by conscientiousness; correlations between the attitudes and rating behavior were strongest for raters who were relatively low on conscientiousness. 相似文献

Classical conditioning of the nictitating membrane response requires a specific temporal interval between conditioned stimulus and unconditioned stimulus, and produces an increase in Protein Kinase C (PKC) activation in Purkinje cells. To evaluate whether biochemical interactions within the Purkinje cell may explain the temporal sensitivity, a model of PKC activation by Ca2+, diacylglycerol (DAG), and arachidonic acid (AA) is developed. Ca2+ elevation is due to CF stimulation and IP3 induced Ca2+ release (IICR). DAG and IP3 result from PF stimulation, while AA results from phospholipase A2 (PLA2). Simulations predict increased PKC activation when PF stimulation precedes CF stimulation by 0.1 to 3 s. The sensitivity of IICR to the temporal relation between PF and CF stimulation, together with the buffering system of Purkinje cells, significantly contribute to the temporal sensitivity. 相似文献

Postoperative Cognitive Dysfunction Versus Complaints: A Discrepancy in Long-Term Findings 总被引:17,自引:0,他引:17
This review describes the discrepancy in findings between postoperative cognitive performance and postoperative cognitive complaints long time after an operation under general anesthesia. Shortly (from 6 hr to 1 week) after an operation a decline in cognitive performance is reported in most studies. However, long time (from 3 weeks to 1–2 years) after an operation this is rarely found although some patients are still reporting cognitive complaints. In general this kind of research is suffering from severe methodological problems (use of insensitive tests, lack of control groups, lack of parallel tests, different definitions of cognitive decline). However, these problems cannot totally explain the discrepancy in findings in the long term. Thus, there are patients who have persistent cognitive complaints long time after an operation, that cannot be measured with cognitive tests. More psychological factors such as fixation on short-term cognitive dysfunction, mood, coping style, and personality are possible explanations for these cognitive complaints in the long term. As a consequence, these factors should be a topic in future research elucidating the persistence of these cognitive complaints long time after an operation under general anesthesia. 相似文献

Classical conditioning of the nictitating membrane response requires a specific temporal interval between conditioned stimulus
and unconditioned stimulus, and produces an incrase in Protein Kinase C (PKC) activation in Purkinje cells. To evaluate whether
biochemical interactions within the Purkinje cell may explain the temporal sensitivity, a model of PKC activation byCa
2+, diacylglycerol (DAG), and arachidonic acid (AA) is developed.Ca
2+ elevation is due to CF stimulation and IP3 inducedCa
2+ release (IICR). DAG andIP
3 result from PF stimulation, while AA results from phospholipase A2 (PLA
2). Simulations predict increased PKC activation when PF stimulation precedes CF stimulation by 0.1 to 3 s. The sensitivity
of IICR to the temporal relation between PF and CF stimulation, together with the buffering system of Purkinje cells, significantly

This article draws on data from a 1999 survey on youth victimization, crime and delinquency in Alberta conducted by the Canadian Research Institute for Law and the Family in collaboration with researchers from the University of Alberta. The survey included 2,001 youth attending Grades 7 to 12 in public and Catholic schools in selected urban and rural areas in the province. Analyses focus on self-reported past-year delinquency. Statistically significant results were found for relationships between extent of delinquency and gender, grade level, psychosocial problems (as measured by conduct, hyperactivity, and emotional problems), and extent of past-year victimization. For low/moderate delinquency, females were comparable to males, and even reported slightly higher rates for low/moderate violence-related delinquency. Younger students were more likely to indicate engaging in violence-related delinquency, while older students were more likely to report property-related delinquent acts. Overall, Grade 9 students had the highest rates of delinquency. For personal characteristics, a high score on conduct problems was most strongly correlated with moderate/high delinquency. The relationship between high levels of delinquency and victimization was stronger for violence-related delinquency than for property-related delinquency. 相似文献
