This Article analyzes potential conflicts that arise from both the judicial and administrative approval processes that govern the closure of charitable hospitals through a sale of all or substantially all of their assets. Examining the recent closure attempt by the Manhattan Eye, Ear & Throat Hospital as an example, the Article highlights the various public health and corporate law issues that are raised when a not-for-profit hospital seeks closure. The Article thoroughly discusses both the statutorily and judicially required approval schemes applicable to the closure of charitable hospitals. The Article also suggests ways in which these conflicts might be avoided or remedied, as well as gives advice regarding hospital board decisionmaking.  相似文献

This study examined the psychological characteristics of a sample of self-reported stalkers in comparison with a control group, on measures of empathy, problem-solving skills, attachment, and borderline personality features. Stalkers were identified by their endorsement of specific behavioral items, consistent with a widely adopted definition of stalking, denoting behaviors that: (a) are repeatedly directed toward an identified target; (b) are intrusive and unwanted; and (c) evoke fear in the victim. Stalkers scored significantly higher than controls on measures of insecure attachment and borderline personality features, suggesting that the stalking group demonstrates a general pattern of inadequate interpersonal attachment, has limited abilities to form and maintain appropriate relationships, is emotionally labile and unstable, and experiences ambivalence regarding their interpersonal relationships. Treatment implications are discussed herein.  相似文献

On request of the International Criminal Tribunal for the former Yugoslavia (ICTY), the Danish-Swedish forensic teams worked in Kosovo during the summer and the fall of 1999. The teams worked mainly as "mobile teams" at sites with few graves. Only two larger sites were examined. Most of the bodies were buried separately. A few "multiple burial" graves were examined, but no mass graves were encountered. The main purpose of the autopsies was to establish the cause and manner of death. Identification was of less importance, but a majority of the bodies had been identified prior to the autopsy. A total of 308 bodies, mainly males, were examined. The age varied greatly with a mean age of 47 years. The most common cause of death was gun shot wounds and the most common manner of death was homicide.  相似文献

Methods for measuring a Russian narcotic analgesic prosidol are suggested: thin-layer chromatography, microcrystalloscopy, gaseous chromatography with ionization flame detector, gas chromatography with mass selective detector, ultraviolet spectroscopy, high-performance liquid chromatography with ultraviolet detector, proton nuclear magnetic resonance used in chemical toxicological analysis, pharmacological analysis, and investigation of material evidence pieces.  相似文献

Gas chromatographic conditions for qualitative and quantitative evaluation of acetonitrile in biological material were determined, including those for reactive gas chromatography. Absolute and relative time of acetonitrile and concomitant substances retention in three columns of different polarity was determined. Study of the time of acetonitrile retention in biological material showed that acetonitrile concentration in the blood virtually did not change in cadaveric material stored in a hermetically closed flask for 2 weeks at 20 +/- 3 degrees C, while its concentration in the stomach decreased by 10-15%. Distribution of acetonitrile in human viscera in lethal poisoning was studied; the agent was evenly distributed in the gastric wall, intestine, liver, and kidney, while its concentrations in the lung and brain were 2-3 times higher. Forensic chemical expert analyses of the blood, urine, and viscera from corpses of humans dead from lethal acetonitrile poisoning showed that lethal concentration in the blood was 28.3-57.0 mg and in the urine 23.2-40.6 mg/100 ml.  相似文献

Theories of judgment in decision making hypothesize that throughout adolescence, judgment is impaired because the development of several psychosocial factors that are presumed to influence decision making lags behind the development of the cognitive capacities that are required to make mature decisions. This study uses an innovative video technique to examine the role of several psychosocial factors—temporal perspective, peer influence, and risk perception—in adolescent criminal decision making. Results based on data collected from 56 adolescents between the ages of 13 and 18 years revealed that detained youth were more likely to think of future-oriented consequences of engaging in the depicted delinquent act and less likely to anticipate pressure from their friends than nondetained youth. Examination of the developmental functions of the psychosocial factors indicates age-based differences on standardized measures of temporal perspective and resistance to peer influence and on measures of the role of risk perception in criminal decision making. Assessments of criminal responsibility and culpability were predicted by age and ethnicity. Implications for punishment in the juvenile justice system are discussed.  相似文献

The pituitary was examined in patients with craniocerebral injuries who died in hospital in various periods after treatment. Control group consisted of victims died at the site of accident. The results indicate the significance of examining the pituitary in craniocerebral injuries for the diagnosis of thanatogenesis, particularly in patients died in hospital. Causes of traumatic changes in the organ were determined, highly incident in the practice of forensic medical experts: directly during injury, as a result of skull bone fractures; during development of dislocation syndrome and in disorders of blood and lymph circulation in the brain matter; resultant from augmenting traumatic edema of the brain.  相似文献
