Demonstration of esophageal varices postmortem by gastroesophageal phlebography

The study presents a method for the demonstration of esophageal varices at autopsy by gastroesophageal phlebography. The veins visible on the radiographs were controlled and evaluated by studying the gross appearance of sections of the esophagus at the level of the varicose veins and by histologic examination of the sections. The phlebography was found to be useful in estimating the varicose and normal veins of the esophagus. The study indicates further that the degree of varicosity is not always proportional to the severity of cirrhosis of the liver, and there may be varicose esophageal veins in patients with liver or heart disorders without hepatic cirrhosis.     

Victims' perceptions of police response to domestic violence incidents

This study examined the nature of police response to domestic violence incidents with a focus on the identification of areas of police intervention that female victims of domestic abuse find “most” helpful and “least” helpful. The first part of the study was based on the analysis of a random sample of incident reports of domestic abuse cases recorded in 2000 and 2001. These reports were examined to obtain information about the characteristics of domestic abuse victims and summary information about the incidents of domestic abuse offenses. The second stage of the research study involved a telephone survey conducted with a random sample of fifty female domestic abuse victims who called the police. The study examined female victims' perceptions of how the police responded to the domestic abuse incidents, how helpful or not so helpful victims found the police to be when they responded to their calls, and how their cases were handled by the legal system.     

Job demands, job resources, and burnout among police officers

The purpose of this study was to examine the relationship between job demands, job resources, and burnout, and to examine if burnout could predict both work and health-related outcomes among police officers. The participants were 223 Norwegian police officers, and data were collected using a questionnaire. The study was part of a national survey of both health care and non-health care professions. The overall level of burnout was low among police officers compared to other occupational groups tested in Norway. Both job demands and job resources were related to burnout, especially work-family pressure was an important predictor for all of the three burnout dimensions. Burnout predicted individual outcomes, such as psychosomatic complaints and satisfaction with life, as well as work outcomes, such as job satisfaction, intention to quit, and organizational commitment. Suggestions for potential interventions to reduce burnout and negative individual and organizational consequences are presented.     

Local law enforcement terrorism prevention efforts: A state level case study

Although law enforcement agencies across the nation have assumed part of the responsibility in the fight against terrorism, significant confusion exists as to the role of local law enforcement. While some agencies have taken steps towards terrorism prevention, little data has been collected on which agencies have taken the greatest steps, how those agencies have changed, and how other agencies should direct their activity. This case study of law enforcement census data from a single state considered variations in terrorism preparedness and predictors of preparedness. Agency size, presence of funding, and other variables significantly predict levels of terrorism preparedness. Important policy implications such as the distribution of funding and which agencies should be working towards terrorism preparedness are discussed.
