As organ transplantation procedures become accepted as standard medical practice, it is anticipated that the frequency of liability claims against transplant care providers will increase. This article examines current statutory and common law analyses of malpractice issues in transplantation, with particular attention given to issues of informed consent as they arise both for the organ donor and donee. 相似文献

In TLC screenings of 335 urine samples taken because of suspicion of heroin consumption, positive evidence of morphine was found in about 50% of the cases, which was confirmed without exception by gas chromatography-mass spectrometry. In 66% of the positive cases, morphine and codeine were found; in about 31% only morphine was found, and the median value of 0.4 mg/l free morphine and 1.0 mg/l conjugated morphine was considerably lower than in the whole collection of samples. Comparison of the codeine/morphine quotients (Q), especially the free bases, proves that the groups of heroin/morphine or codeine consumers can be distinctly differentiated. The critical conditions of the conjugated bases worked out by Dutt et al. (1983) proved to be right. Using the equation Qf less than 0.5 square root c, a boundary condition for the free flare bases can also be developed, which is dependent on the sum of the codeine and morphine concentrations and which proves heroin/morphine consumption with 98% certainty. 相似文献

- The past ten years have been marked by significant changes in technology, politics and economics. These changes have affected the social and regulatory environments in which public affairs (PA) officers operate. This paper describes how PA officers at 74 large US corporations perceive these environmental changes and how PA activities have changed from ten years ago.
- The data reported in this paper were collected first in 1993, then again in 2003. The results show a rather even split between respondents: half (39) believe that their political/regulatory environment is simpler today than was the case ten years ago, half (33) believe that it has become more complicated; half (35) believe there is less social interest in their operations and half (32) believe there is more. The paper then examines the changes in PA activities and performance over the past ten years
- Overall, PA officers are more pleased with their performance (at least in managing social issues and achieving social objectives) than they were in 1993.

When discussing the biases of the U.S. Electoral College, researchersconclude that competitive states seem to occur randomly withoutany explanation. This study examines the consistency with whichthe same states have been competitive in presidential electionsfrom 1824 to 2000. It also identifies "spectator" states. Spectatorstates are those that have not been competitive for ten presidentialelections in a row. A statistical analysis illustrates thatthe identities of competitive states have become more unpredictable.In addition, few states have been spectators for long periods.In terms of representation, the facts that competitive statesare not consistent and that there are few spectators mean differentstates are in the presidential spotlight at different times.As opposed to any biases associated with the Electoral College,the changes in consistency coincide with the rise of candidate-centeredpolitics and decreasing voter loyalty to parties. The highlychangeable nature of competitive states strengthens the federalismargument for continuation of the Electoral College. 相似文献

A prospective study of 161 victims of falls from height is reported. The aim was to determine the interest of systematic qualitative and quantitative toxicological analysis in such fatalities. The primary cause of death was suicide (84.5%), followed by accidents (7%) and homicide (1%). In the remaining 7.5%, cause of death was undetermined. In the suicides, there was evidence of psychotropic medicines in 57% of the observations, with a much higher proportion of benzodiazepines and antidepressants in women than in men. Quantitative toxicologic analysis showed overdosing on medication in 16 suicide victims, with toxic levels in 11 of these. Systematic qualitative and quantitative toxicologic analysis made a significant contribution to the diagnosis of suicide by revealing either an unknown psychiatric treatment or a toxic level. 相似文献

Homicide-suicide forms a distinct form of homicide. An analysis of cases in the Yorkshire and Humberside region of England between 1991 and 2005 revealed 37 episodes with 42 victims. Previous studies have shown a high rate of use of firearms. Over the last 2 decades firearms legislation has become more restrictive. In this study all assailants were male, mean age 46.8 years. The commonest method of homicide was strangulation (36%) with 16% killed by firearms. This is a reduction compared with a previous study in the same region. All killers who shot their victims killed themselves with firearms. There were no multiple killings with firearms in this study and no stranger killings. Hanging was the commonest method of suicide. During the same period the use of firearms as a method of homicide increased in England and Wales with handguns, the most common weapon. Nationally, suicide after homicide has remained at a similar rate over the half century and is an uncommon phenomenon. Firearms use remains low in both homicide and homicide-suicide episodes in England, and further analysis is required to determine changes in patterns of killing. 相似文献

This study examined the association of victimization in a physically violent dating relationship with risk behaviors, age of risk behavior initiation, and co-occurrence of risk behaviors among students in grades 9 through 12 in the United States. Data were from the 2003 national Youth Risk Behavior Survey (YRBS). Nearly 9% of students reported experiencing dating violence victimization. Dating violence victimization was associated with alcohol use, marijuana use, and having ever had sexual intercourse among female students and having ever had sexual intercourse among male students. Dating violence victimization also was associated with early initiation of alcohol use among female students. The odds of dating violence victimization increased as the number of risk behaviors increased and as the number of lifetime sexual partners increased. These risk behavior patterns should serve as warning signs of elevated risk for dating violence victimization and may be helpful in identifying adolescents who could benefit from targeted, preventive interventions. 相似文献

This study sought to determine the screening practices of child and adolescent psychiatrists regarding adolescent dating violence (DV). A questionnaire regarding screening practices for DV and other risk behaviors was administered to 817 child and adolescent psychiatrists via the Internet and mail. Twenty-one percent of clinicians screened for DV "more than 90% of the time," and 65% had identified it in the past year. Multiple logistic regression analyses found that screening for DV was associated with consistent screening for either substance use or interparental violence (OR=3.0 and 6.3, respectively). Despite the prevalence of DV, only a minority of psychiatrists screen their adolescent patients for this type of risk. These data suggest that screening for DV is associated with consistent screening practices for other risk behaviors. Screening rates may be improved with training and adherence to specific protocols. 相似文献

Partner violence may have significant consequences on women's employment, yet limited information is available about how women cope on the job with perpetrators' tactics and the consequences of her coping methods on employment status. This article investigates whether there is an association between workplace disclosure of victimization and current employment status; and whether there is an association between receiving workplace support and current employment status among women who disclosed victimization circumstances to someone at work. Using a sample of partner victimized women who were employed within the past year (N = 485), cross-tabulation and ANOVA procedures were conducted to examine the differences between currently employed and unemployed women. Binary logistic regressions were conducted to examine whether disclosure and receiving workplace support were significantly associated with current employment. Results indicate that disclosure and workplace support are associated with employment. Implications for clinical practice, workplace policies, and future research are discussed. 相似文献

In general research suggests partner violence has a negative impact on women's employment. However, there has been limited examination of partner stalking and consequences for employment. The purpose of this study was to examine partner stalking and employment consequences among two samples of women. One sample was women who had obtained a protective order against a violent partner and had worked in the prior year (n = 482), about one half of these women were stalked by their violent partner and one half were not. The second study examined qualitative information from women recently stalked (n = 62) by a violent partner. Results from both studies suggest that women who were stalked by a violent partner were significantly more susceptible to on-the-job harassment and problems. Also, women reported that stalking by a partner interfered in their work through on-the-job harassment, work disruption, and job performance problems. Implications for policy and research are discussed. 相似文献
