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.

International institutions and market expectations: Stock price responses to the WTO ruling on the 2002 U.S. steel tariffs

Many scholars assert that international institutions have little power to enforce laws, punish offenders, or force compliance. Others stress that international institutions are important actors, specifically in the regulation of international trade. In this paper, I show that the recent trade dispute over U.S. steel protection provides us with a critical case to evaluate the role of the World Trade Organization in settling trade disputes and specifically stabilizing expectations of market actors over future steel policy. I argue that stock prices can serve as an important tool in answering these questions. In an empirical analysis using daily steel stock prices, I find that during the 2002 WTO steel case, the WTO dispute mechanism helped market actors stabilize expectations of future trade policy.

US Presidential popularity and opportunities to coerce North Korea: a quantitative test 1990 2000

This paper investigates how North Korean behaviour towards boththe United States and South Korea is influenced by the popularityof the American President. The study applies theories relatingto strategic conflict avoidance and signalling to suggest thatthe American President is able to demonstrate a willingnessto use force when he is unpopular and as such is better ableto coerce Pyongyang. Using a time-series model, I demonstratethat the North Koreans become more cooperative towards the UnitedStates in response to decreases in presidential popularity andincreasing levels of US inflation. However, the study also showsthat the North Koreans do not alter their behaviour towardsthe South Koreans in response to low American President Popularityratings. The research, therefore, suggests that the North Koreansbelieve that the United States would be unable to launch a diversionaryattack in response to North Korean behaviour towards the South.This study provides a clear support for the strategic avoidanceof conflict hypothesis and suggests that the American Presidentsare best able to coerce North Korea when they are unpopularat home.

Spatial variation of refractive index in a pane of float glass.

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane.     

Uncovered bones on the Baltic Sea beach--human or animal?]

Report of an unusual finding of bones on the shore of the Baltic Sea. Although the morphological findings appeared similar to a human foot skeleton, a quick identification as sea dog bone was possible.     

A statistical approach to drug sampling: a case study.

In many countries it is left to the discretion of the court to accept or reject conclusions based on sampling procedures as applied to the total drug exhibit. As an alternative to this subjective approach, a statistical basis is presented using binomial and hypergeometric distributions to determine a lower limit for the proportion of units in a population which contains a drug, at a given confidence level. A method for calculating the total weight of a drug present in a population within a given confidence interval is also presented. In the event of no failures (all units sampled contain a drug), a sample size of six or seven units is generally sufficient to state that a proportion of at least 0.70 of the population contains a drug at a confidence level of at least 90%. When failures do occur in the sample, point estimation is used as the basis for selecting the appropriate sample size.
