Workplace violence covers a wide spectrum of incidents of aggression that may occur at work. One area of particular concern relates to holdups. This study reviewed all incidents of robbery (holdups and bag snatches) occurring in a quasi-government wagering organization throughout Queensland, Australia between 1990 and August 1993. The study covered 30 robberies, at 28 sites with 34 subjects, 22 of whom consented to complete a questionnaire related to the stressfulness and impact of the event. Most robberies occurred at opening or closing time, at sites situated on a main thoroughfare, predominantly on a Monday. Single males (n =15) or a pair (n =15) mostly carrying a gun were the perpetrators. Nineteen of the 22 victims attended critical incident debriefing and most found this valuable. Only one subject interviewed lost time for stress (and this was the fourth time she had been robbed). One subject not interviewed was hospitalized. Other subjects had minor physical injuries, but suffered emotionally for up to a year after the incident. Recommendations focused on the hierarchy of control (environmental and engineering controls in preference to people-focused change). Additionally training in the normal processes of grief and trauma was recommended.  相似文献

Treisman and Gelade's (1980) feature-integration model claims that the search for separate ("primitive") stimulus features is parallel, but that the conjunctions of those features require serial scan. Recently, evidence has accumulated that parallel processing is not limited to these "primitive" stimulus features, but that combinations of features can also produce parallel search. In the experiments reported here, the processing of feature conjunctions was studied when the stimulus features of a combination were at different spatial scales. The patterns in the search array were composed of three cross-shaped or T-shaped (local) elements, which formed an oblique bar (the global pattern) 45 deg or 135 deg in orientation. When the target and distractors differed from each other at one spatial scale only (either in the bar orientation or in the shape of the local elements), target detection was independent of the number of distractors, i.e., the search was parallel. In the conjunction task, in which the target and distractors were defined as the combinations of the bar orientation and the element shape, i.e., both spatial scales were relevant, the detection of the target required slow serial scrutiny of the search array. It is possible that the conjunction search could not be performed in parallel because switches between the two scales (or spatial frequency channels) are linked to attention and the task required the use of both scales in order to find the target.  相似文献

A multiracial/multiethnic sample of middle school adolescents and their teachers was used to assess whether teacher ratings of student behavior problems varied according to teacher-student racial/ethnic differences and students' perception of teachers' attitudes toward them. No significant mean score differences were found for Hispanic or non-Hispanic white students according to the race/ethnicity of the teachers doing the ratings. However, African American students rated by Hispanic and non-Hispanic white teachers had significantly higher mean total behavior problem scores than African American students rated by African American teachers. Teacher ratings were also compared to those made by parents. The percentage of students rated as cases by teachers but not by parents differed significantly by race/ethnicity of student. Other findings indicated highly significant relationships between student-perceived teacher disparagement and the assignment of high behavior problem scores to students by teachers. This research was supported by a grant from the National Institute on Drug Abuse, R01DA05912; William A. Vega, Principal Investigator. The authors express their appreciation to Superintendent Octavio Visiedo, Dr. James Mennes, Dr. Sylvia Rothfarb, and the cooperating staff and teachers of the Dade County Public Schools for their support in the conduct of this research.  相似文献

Qualia in the node-point between mind and body: Dilemma of present discussion about the subjectivity of mental states. The present discussion about qualia shows a bewildering variety of different positions. We show implicit assumptions about brain, subject, and qualia of this complex discussion. By means of three assumptions we divide the discussion about qualia into three different positions (proposition, opposition, intermediate solutions). These positions and their exemplaric authors are briefly presented along the lines of the three assumptions. The next step shows how each position solves the dilemma which arises if one relates all three assumptions by eliminating at least one of the three assumptions. Finally, general problems in the discussion of qualia are shown by means of which the dilemma of the relation between brain, subject and qualia may be brought closer to a solution without eliminating one assumption.  相似文献

Forty-five adolescent boys from abusive and depriving homes were not doing well in positive peer culture residential care. Despite their backgrounds, given a modified form of the Relational Ethics Scale, they indicated that their relational life with their families of origin was trustworthy, fair, and worthy of continued devotion. In contrast, on the Firo-B these same boys demonstrated distrust of others outside of their families and an unwillingness to get involved. These results support the inference from contextual family theory that peer group interventions cannot bypass identification and resolution of the injustices that took place in the family of origin.This project was fully supported by Teen Ranch, Inc., Marlette, MI 48453.  相似文献
