Survey research was conducted to examine the effects of education, perceptions of community attitudes, and career commitment
upon overall job satisfaction of campus law enforcement officers in North Carolina. Thirteen (13) campus departments participated
in the 1984 study. Findings revealed both significant and insignificant relationships. The attained level of post-secondary
education was not significantly related to an officer’s perception of having his/her authority questioned, nor was education
related to an officer’s feeling of boredom with the job. However, significant relationships were found between several variables
including an officer’s willingness to recommend the job to another person and his/her perceptions of community attitudes and
the rank of the officer and his/her commitment to the current position.(1) 相似文献

An analysis of child care regulations in Germany, Sweden, and the United States reveals distinctive national policy styles.
A ‘social constructionist’ perspective, with its emphasis on variable problem definitions, helps to explain such differences.
However, a full understanding of regulatory differences requires attention to regulatory solutions as well. By disaggregating
the concept of regulation, we are able to demonstrate rather different rank-orderings of our three countries in their regulatory
solutions. We attribute these differences to cultural, institutional, and political characteristics of the three countries. 相似文献

To date, relatively little is known about differences between perpetrators and victims of cyber and traditional forms of aggression.
Hence, this study investigated differences among traditional and cyber aggressors and victims on psychosocial characteristics
typically examined in research on traditional aggression and victimization, specifically effortful control, manipulativeness,
remorselessness, proactive and reactive aggression, and anxious/depressive symptoms. Participants (N = 300; 63.2% female; M age = 12.89, SD = .95; 52% Caucasian, 27% African American, 11% Latino, and 10% other) were categorized based on aggressor
type (non/low aggressor, traditional-only, cyber-only, and combined traditional and cyber) and victim type (non-victim, traditional-only,
cyber-only, and combined traditional and cyber). Cyber aggressors reported lower levels of reactive aggression compared to
traditional-only and combined aggressors. Combined aggressors demonstrated the poorest psychosocial profile compared to all
other aggressor groups. For victimization, cyber-only and combined victims reported higher levels of reactive aggression and
were more likely to be cyber aggressors themselves compared to traditional-only victims and non-victims. Findings suggest
that there may be unique aspects about cyber aggression and victimization that warrant further investigation. 相似文献

Stress is known to amplify the link between pubertal timing and psychopathology. However, few studies have examined the role
of peer stress as a context for this link. The present study examined the interaction between perceived pubertal timing and
peer stress on symptoms of psychopathology in early adolescence. The sample consisted of 264 students (63% female; M
age = 12.40, SD = 1.00; 55% Caucasian, 23% African American, 7% Latino, 11% biracial and 4% other). Higher peer stress was associated
with symptoms of anxiety/depression; this effect did not vary by timing or gender. However, early-maturing girls with high
peer stress demonstrated higher rates of relational and overt aggression compared to other girls. Findings also suggested
that late-maturing boys with high stress are at risk for aggression problems; however, due to the small number of boys, analyses
were exploratory. Overall, results suggest that developmentally salient contexts as indicated by stressful peer experiences
may pose unique threats to early maturing girls and possibly late-maturing boys. 相似文献

A 36-year-old woman consulted the medical emergency unit of a private health center for abdominal pain and gastroenteritis of 5 days duration. Acute right pyelonephritis was diagnosed. Five hours after admission she became unconscious in a state of clinical shock. She was transferred to an intensive care unit but resuscitation attempts were unsuccessful and she died 3 h later. Three days after death, she was buried in the family vault. Five days after the burial, her husband lodged a complaint with the public prosecutor because he had not received a clear explanation from the physicians concerning the cause of his wife's death. After analysis of the medical records of the deceased by two forensic pathologists, a medicolegal autopsy was ordered by the public prosecutor. The corpse was exhumed and autopsy performed 9 days after death. Massive hemoperitoneum was diagnosed with a macroscopically ruptured subcapsular hematoma. Pathological study confirmed acute right pyelonephritis and demonstrated the precise cause of the hemorrhage: rupture of the hepatic artery at the hilar part, following infectious arteritis which was probably secondary to the acute pyelonephritis. To the best of our knowledge, this is the first published report of such a case. 相似文献

The democratic foundations of European integration in the foreign and defence realm are increasingly being debated. This article looks at the question of democratic legitimacy from one particular angle, by examining public opinion as measured in Eurobarometer surveys between 1989 and 2009. Based on reflections about the relation between polling results and wider questions of democracy, it examines three aspects of public opinion: general support for a common foreign and a common defence policy; differences among support rates in EU member states; and what roles Europeans would prefer for European armed forces. It turns out that general support for a common foreign policy is high, whereas the desirability of a common defence policy is much more contested. Moreover, citizens across Europe would prefer European armed forces to take on traditional tasks, as territorial defence. An EU defence policy that goes beyond strict intergovernmentalism and is directed towards protecting international law and universal human rights would thus require a significant communicative effort to become accepted. 相似文献
