A 6-month-old girl died suddenly without any previous symptoms of heart failure. Autopsy examination showed cardiomegaly (97 g) with a severely fibrotized myocardium. The left coronary artery was originating from the pulmonary artery. Histologically, the myocardium showed myocardial infarcts of different ages, as well as grossly thickened arterial branches due to increased flow in left-right shunt. We suggest that rare anomalies of the coronary arteries should be considered in the autopsies of suspected sudden infant death syndrome cases. 相似文献

The impact of high temperatures (24 to 39 degrees C) and low to moderately high humidities (20 to 70%) on the applicability of TLC systems for drug identification was studied during a 6 month climatologic cycle in Burkina Faso (West Africa). In general, the Rf values as observed on the plates were found to be substantially affected as compared with values obtained at temperate climates. Some TLC systems were more affected than others and the largest deviations of up to 30 Rf units were at low humidities. Tropical conditions also had a negative effect on the reproducibility of Rf values. However, when an Rf-correction procedure was applied, using reference mixtures of known drugs on each plate, accuracy as well as reproducibility of the resulting Rfc values were drastically improved and data thus corrected were found to be compatible with existing TLC data bases developed under moderate climatological conditions. The impact of high to extremely high humidities (70 to 100%) remains to be investigated. 相似文献

Many attempts have been made over the last several decades to improve communication among law enforcement agencies. This article
is a case study of a “low-level” data sharing project in Florida that could serve as a national model. The Florida Law Enforcement
Data Sharing Consortium is a partnership between the University of Central Florida and more than one hundred law enforcement
agencies. It offers an inexpensive, yet technically advanced alternative to the proprietary data sharing model. Its distributed
architecture was endorsed by the Markle Foundation, the 9/11 Commission, and the 2004 National Security Act. Civil liberties
concerns raised by this and other types of data sharing projects are discussed. 相似文献

Experiencing a criminal victimization is among one of the most stressful human experiences. A cross-sectional study of victims of violent crime and victims of nonviolent crime suggests that there are statistically significant differences in experiences in the initial aftermath of the crime event and a few common effects. This article describes the common effects that are associated with criminal victimization in the context of intense distress and discusses the theoretical implications of well-being in the coping process. One hundred seventy-five victims of violent or nonviolent crime were interviewed. Implications for social work practice and theory and future research are delineated. 相似文献

U.S. Supreme Court Justice Thurgood Marshall offered his opinion regarding the utility of public opinion polls as a tool for assessing the “evolving standards of decency” regarding capital punishment. His arguments became known as the Marshall hypotheses and spawned a considerable body of empirical testing. The three Marshall hypotheses are: (1) support for capital punishment is inversely associated with knowledge about it, (2) exposure to information about capital punishment produces sentiments in opposition to capital punishment, but (3) exposure to information about capital punishment will have no impact on those who support it for retributive reasons. The results of previous tests of these hypotheses were somewhat mixed but supportive. None of these studies, however, examined the effects of change in knowledge levels with changes, if any, in death penalty attitudes and beliefs as needed for a more complete test of the Marshall hypotheses. The present study addressed this shortcoming. The results provided mixed support for these three hypotheses. That is, death penalty supporters were somewhat less informed than death penalty opponents; exposure to death penalty information and knowledge gains tended to be associated with attitudinal change in a directions suggested by these hypotheses; but, retributivists' attitudes toward and beliefs about capital punishment were not any more resistant to change than were the attitudes and beliefs of non-retributivists. 相似文献

This article reports the results of a study of the antecedents of long-term success in community mediation. Seventy-three mediation sessions were recorded and content analyzed. The participants were interviewed at two points: immediately after mediation and 4 to 8 months later. No relationship was found between the quality of the agreements—i.e., the extent to which they solved immediate problems- and long-term success as measured by compliance, improved relations between the parties, and the absence of new problems. On the other hand, joint problem solving by the disputants was related to complainant perceptions of improved relations with the other party. Also respondent perceptions that the mediation had been fair and that all the problems had come out were related to all aspects of long-term success in the eyes of the complainant. The latter results support a procedural justice analysis of mediation and underline the importance of mediator attention to the respondent. 相似文献

Research indicates that senators evaluate U.S. Supreme Court nominations on two ideological dimensions: the distance between themselves and the nominee, and the potential effect confirmation would have on the Court median. My analysis of nominations from 1968 to 2006 provides evidence that senators are also influenced by the ideological contrast between the nominee and the departing justice. 相似文献

This article assesses the effects of one jurisdiction's attempt to control its lockup population through creation of a separate processing center designed to expedite initial processing of individuals charged with misdemeanors and minor felonies. In the new center, cases were screened and initial hearings held around-the-clock, seven days per week. “Before” and “after” samples of arrestees are compared on prosecutorial screening time, time to court, and time in custody. The results show significant reductions in case screening and length of time to initial court hearing. Individuals released on recognizance and those with no charges filed spent significantly less time in custody and saved considerable bed space for the jurisdiction. Individuals with bond set experienced no reductions in length of custody. Collateral consequences of the new facility included improved procedural justice, expanded detention capacity in the county, and an end to part of the federal litigation. 相似文献
