Purpose
To examine the effect of victimization on self-control.Method
Five waves of data from the GREAT survey are analyzed; the effect of prior victimization on subsequent self-control is estimated using the dynamic panel generalized-method of moments.Results
Victimization reduces subsequent self-control in the near term.Conclusions
The findings point to another source of low self-control, help to explain why prior victimization is linked to subsequent victimization, and provide support for general strain theory - which predicts that strains such as victimization will reduce self-control. 相似文献43.

Homeland Security Preparedness: The Rebirth of Regionalism 总被引:1,自引:0,他引:1
The homeland security mission has placed many new demands onthe U.S. system of federalism. The successful implementationof homeland security policy requires cooperation among all levelsof governmentfederal, state, and local. Regionalism offersa powerful tool for encouraging greater intergovernmental cooperationand improved homeland security preparedness. We assess the impactof regionalism on intergovernmental cooperation and the implementationof the homeland security mission in Florida, an early proponentof the regional approach. From a regional perspective, we evaluatehow intergovernmental complexity, the quality and quantity ofintergovernmental networks, and security vulnerabilities contributeto perceived improvements in intergovernmental cooperation andhomeland security preparedness. The results of a 2004 mail surveyof city and county officials suggest that regional organizationalstructures are most effective in promoting intergovernmentalcooperation and preparedness where the intergovernmental landscapeis the most complex and where security vulnerabilities are themost intense. 相似文献

Stab-resistant body armour is now becoming a standard item of equipment for police officers in the United Kingdom. In the UK these are usually required to have a stab resistance as specified by the Police Scientific Development Branch KR42 standard [G. Parker, PSDB Stab Resistant Body Armour Test Procedure, Police Scientific Development Branch, Publication No 10/93, 1993]. There are several other test standards, all of which specify that body armour must resist penetration by a specific blade type delivered at a specific energy level or range of levels. However, the actual range of energy levels specified varies over almost an order of magnitude and the basis for these levels is not clearly defined. This paper describes tests to determine the energy range and characteristics of stabbing actions that might be directed against stab resistant body armour by an assailant. The energy and velocity that can be achieved in stabbing actions has been determined for a number of sample populations. Volunteers were asked to stab a target using an instrumented knife that measured the axial force and acceleration during the stabbing. The maximum energy obtained in underarm stabbing actions was 64 J whilst overarm stabbing actions could produce 115 J. The loads produced on contact with the target often approached 1000 N. 相似文献

GC and GC/MS analysis was used to detect cocaine and cocaethylene in hair extracts of mice injected with 20 mg/kg cocaine hydrochloride or an equivalent dose of cocaethylene fumarate twice daily for 3 weeks. Some mice were fed liquid Lieber-DeCarli diets containing ethanol (26% of total calories) and injected twice daily with the same doses of cocaine or cocaethylene or combination of cocaine and morphine (5 mg/kg). The average concentrations of cocaine in different experimental groups were in the range of 0.9-2.4 ng/mg of hair and for cocaethylene, 2.4-2.8 ng/mg of hair. There were no significant differences in hair concentrations of cocaine among groups receiving cocaine treatment, nor were there significant difference in cocaethylene concentration in hair in the two groups administered cocaethylene. In hair extracts of mice treated with cocaine and ethanol, levels of cocaethylene were below the limit of detection. 相似文献
