The controversial decision to ban fracking in New York State, most notably in the Marcellus Shale formation, was informed by global, national, state, and local issues that have general relevance. Without prejudging whether fracking can be undertaken safely, we discuss the science of fracking, focusing primarily on widely reported public health and environmental risks, especially those associated with greenhouse gas emissions. Based upon such concerns, any reconsideration of the fracking ban in New York should include, at a minimum, consideration of imposing public and environmental health risk management requirements as proven feasible and successful via industry experience. Fracking should be viewed as one choice among alternative energy strategies, all of which pose risks, rather than simplistically classified as either safe or unsafe. Assuming that our energy needs will continue to grow, our goal should be to guide the evolution of our energy portfolio toward sustainable sources as they emerge as feasible energy alternatives.  相似文献

Ethanol has been detected in the majority of medical examiner cases involving nonnatural death and in a substantial number of natural deaths. The higher the serum alcohol concentration (SAC), the greater were the odds that death was due to external (traumatic) causes. We identified 149 medical examiner cases that were positive for ethanol and negative for 11 major drug of abuse groups, and studied those cases to further clarify ethanol-related risk factors and behaviors. Based on terms of frequency of occurrence, the data identify SACs of 201 mg% to 300 mg% as a particularly high risk factor for sudden, unexpected, traumatic death. Traumatic deaths associated with SACs below 100 mg% were infrequent, and attendant opinions concerning the contributory role of ethanol must be made with circumspection. SACs below 150 mg% could not be used to predict whether or not the decedents had been engaged in active or sedentary behavior prior to death because both situations occurred with equal frequency. At SACs between 151 mg% and 350 mg%, active situations were observed three times as often as sedentary situations. When SACs were 350 mg%, sedentary situations were observed twice as often as active situations. Suicide victims and driver fatalities rarely showed SACs above 350 mg%; therefore finding such SACs in apparent suicidal or driver fatality situations should prompt a thorough investigation to rule out other possibilities.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

In Gottfredson and Hirschi’s (1990)A General Theory of Crime, criminal and analogous behaviors are argued to be the result of a stable individual psychological trait referred to as “low self-control.” In this article, we test the proposition that low self-control is a stable characteristic. We conduct a two-wave panel study that measures the self-reported self-control of college students at two relatively close time points. Our test of the stability hypothesis includes conducting four separate analyses of the data (t-tests, correlations, individual change scores, and HLM analyses). In general, we find that most of the dimensions of self-control, and the overall self-control construct, appear to be relatively stable across this short period of time. However, given that the measurements were taken closely together and that we do not find correlations as strong as might be expected, at points the strength of the stability is somewhat unclear.

BACKGROUND: Medical examiner and coroner offices may face difficulties in trying to achieve identification of deceased persons who are unidentified or in locating next of kin for deceased persons who have been identified. The Fulton County medical examiner (FCME) has an office web site which includes information about unidentified decedents and cases for which next of kin are being sought. METHODS: Information about unidentified deceased and cases in need of next of kin has been posted on the FCME web site for 3 years and 1 year, respectively. FCME investigators and staff medical examiners were surveyed about the web site's usefulness for making identifications and locating next of kin. RESULTS: No cases were recalled in which the web site led to making an identification. Two cases were reported in which next of kin were located, and another case involved a missing person being ruled out as one of the decedents. The web site page is visited by agencies interested in missing and unidentified persons, and employees do find it useful for follow-up because information about all unidentified decedents is located and easily accessible, electronically, in a single location. CONCLUSIONS: Despite low yield in making identifications and locating next of kin, the UID web site is useful in some respects, and there is no compelling reason to discontinue its existence. It is proposed that UID pages on office web sites be divided into "hot" (less than 30 days, for example) and "warm" (31 days to 1 year, for example) cases and that cases older than a year be designated as "cold cases." It is conceivable that all unidentified deceased cases nationally could be placed on a single web site designed for such purposes, to remain in public access until identity is established and confirmed.  相似文献

CONTEXT: Alcohol can contribute to various manners of death by acute intoxication that places a person at risk for fatal injury, acute fatal alcohol poisoning, or the various fatal complications of chronic abuse with or without superimposed acute intoxication. The reporting of alcohol use on the death certificate may vary with office policy or procedure, certifier judgment, and the timing of information received during investigation. OBJECTIVE: To determine the number of deaths including mention of alcohol use in the investigative case file, the number of death certificates on which alcohol use is reported, the number of discrepancies between the 2, and the possible reasons for observed discrepancies. DESIGN, SETTING, AND PARTICIPANTS: Retrospective case review of all deaths where alcohol use was mentioned in the investigative case file and/or on the death certificate for deaths investigated by the Fulton County Medical Examiner in Atlanta, Georgia, during a 1-year period between January 1, 2004, and December 31, 2004. MAIN OUTCOME MEASURES: Percentage of deaths with alcohol use reported on the death certificate, tabulation of where and how alcohol use is reported on the death certificate, and tabulation of the differences between the investigative case file and death certificate regarding alcohol's possible role in causing death. RESULTS: Among the 1324 deaths certified by the office, 105 (8%) had alcohol use reported on the death certificate. The majority (67%) of these cases were natural deaths. Sixty-nine (5%) deaths had mention of alcohol use in the investigative case notes but did not include it on the death certificate. Twenty-five (2%) deaths had mention of alcohol on the death certificate but did not have mention of it in the investigative case file based on our search criteria. However, subsequent review of additional case follow-up information disclosed a history of alcohol use or acute intoxication in each case. CONCLUSIONS: The data show that more natural deaths are considered to be directly caused by alcohol than other manners of death. For the unnatural manners of death (excluding acute alcohol poisoning), alcohol use is often viewed by medical examiners as an incidental, associated finding or risk factor surrounding the circumstances of death rather than being an actual cause of death. In such cases, alcohol use is often omitted from the death certificate. For deaths directly caused by alcohol, the proportion of cases involving possible underreporting or overreporting of alcohol involvement was relatively small and usually involved the omission of chronic alcohol use from the death certificate. Researchers need to be aware of potential limitations of death certificate data for studying alcohol-related deaths.  相似文献

A total of 53 in-custody deaths that occurred in Atlanta-Fulton County, Georgia, between 1974 and 1985 are reviewed. Custody deaths showed characteristics similar to those described in other geographical areas. The majority of deaths were due to natural causes, about one-fourth were suicides, and homicides were rare. For jails that housed a daily population of about 1,000 prisoners, an average of 4.4 deaths were observed annually. Men predominated, and racial makeup paralleled the general prison population. Seizures, alcohol-related illness, and cardiovascular disease caused over half of the natural deaths. All suicides were accomplished by hanging. Over two-thirds of the incidents that led to death occurred in the prisoner's cell, and about one-half of the victims were found dead in their cells. Two-thirds of those who died in custody had been arrested for crimes in which persons were not harmed, while nearly two-thirds of those committing suicide had been arrested for crimes against persons. Deaths in custody are expected events, and familiarity with the circumstances under which they occur should be helpful in enabling prison managers to establish policies and procedures to minimize their occurrence.  相似文献

Since the development of electronic-monitoring programs in the early 80s, questions have surfaced concerning the similarities between institutionalization policies and electronic-monitoring policies. In the Commonwealth of Virginia, recent debate has centered on whether offenders on electronic monitoring should be awarded good-time credits. This article addresses the use of good-time for electronically monitored offenders by content analyzing comments of thirty electronic-monitoring program supervisors surveyed by the Virginia State Crime Commission in 1997. The data suggest that good-time policies can be useful for electronic-monitoring programs in some situations.  相似文献
