To investigate the use of ninhydrin-reactive nitrogen (NRN) in gravesoil to estimate early postmortem interval (PMI), we conducted an experiment to decompose swine (Sus scrofa) carcasses of contrasting mass (~1 kg, ~20 kg, ~40 kg, ~50 kg). Carcasses were placed on the soil surface during June 2007 to monitor mass loss and the concentration of gravesoil NRN over an interval of 15 days. Carcasses of a mass ≤ 20 kg decomposed more rapidly than larger carcasses. However, 1 kg carcasses were associated with a slower release of NRN into gravesoil but a greater concentration of NRN per kg carcass (NRN(C)). We conclude that carcass mass can affect the rate of decomposition and release of NRN into gravesoil, which reflects an interaction between carcass volume and blow fly colonization. Furthermore, we conclude that neonatal carcasses require a different equation than larger carcasses when using gravesoil chemistry to estimate PMI. 相似文献

Interviews were conducted with parents of 136 female and 45 male adolescents categorized into risk groups for the later development of an eating disorder. The family and school concomitants of risk status in females were demonstrated to be different from that in males. Risk group female adolescents rated family cohesion, parent-adolescent communication processes, and overall family satisfaction more negatively than the comparison group. Mothers of moderate risk group females reported lower family cohesion than the comparison group; there were no group differences for adolescent females in fathers' ratings of family measures. However, no group differences were found on any of the family measures between male risk and comparison males. For both females and males, there were no significant group differences in family history of eating and mood disorders, or alcohol dependence. Teacher ratings indicated relatively greater internalizing tendencies in the high-risk female group.This investigation was supported by NICHD Grant Number 1R01-HD24700 awarded to Gloria R.

Obesity has attained epidemic proportions in the United States, with more than 50% of adults classified as overweight or obese. If untreated, morbidly obese patients have a 1 in 7 chance of reaching normal life expectancy. The surgical treatment of obesity has emerged as the most effective treatment modality in long-term weight control and has become increasingly popular, with attendant postoperative complications and death. We performed a cross-sectional, coroner based, 2-year retrospective review of archival case records for decedents who died following bariatric surgery for the treatment of obesity to identify underlying causes of death and forensic characteristics of this cohort. Fifteen (0.5%) out of 3097 archival cases died following bariatric surgery, with approximately 73% of decedents dying within 6 months of surgery. The underlying causes of death in 80% of decedents were natural comorbidities of obesity, with cardiovascular diseases (33%) being the most frequent causes of death, followed by gastrointestinal diseases (20%), acute pulmonary thromboembolism (13%), and acute bacterial pneumonia (13%). The majority of decedents were white females who remained morbidly obese after bariatric surgery. Only 2 decedents died of direct inadvertent/accidental surgical complications. 相似文献

Lugol's iodine staining technique was used to examine oral samples from 10 men and 10 women. Examination of saliva samples before and after extraction with water shows that the low levels (49 positive cells and 3,951 negative cells) of glycogen in buccal epithelial cells become even lower after water extraction (0 positive cells and 4,000 negative cells). In addition to the 20 samples used in this paper, 40 oral swabs extracted with water were examined under classroom conditions with much less than 1% of the epithelial cells being positive for glycogen. Furthermore, 119 saliva samples from chewed gauze in sexual assault kits were extracted with water and all of them yielded less than 1% glycogen positive cells. This paper proposes that when more than 1% of the nucleated squamous epithelial cells are glycogen positive with Lugol's test after extraction in water, it is reasonable to eliminate the mouth as a source of these glycogen positive cells. 相似文献

The Bosnian War (1992–1995) was one of the most brutal conflicts in Europe since the end of World War II. Thirty‐four cease‐fires failed to produce peace in Bosnia and Herzegovina until the late American diplomat, Richard Holbrooke, brokered one that set the stage for a series of negotiations—starting in the Balkans and ending in Dayton, Ohio. The Dayton peace process finally terminated the Bosnian War. The interplay of military intervention by the North Atlantic Treaty Organization and diplomacy by the United States was remarkable. This article highlights thirteen conflict resolution lessons or “Holbrookeisms” that can be learned from the Dayton peace process. Some aspects of Holbrooke's approach toward the peace process helped him to successfully mediate an end to the Bosnian War, while others contributed toward some of the existing cleavages in today's Bosnian society. 相似文献

Social Context,Institutional Capacity,and Police Services: A Local Public Economies Perspective 下载免费PDF全文
Agustin Leon‐Moreta 《Public administration review》2018,78(2):270-283
This article examines levels of policing services, focusing on an assessment of resources and their measurement for municipalities. Two measures of policing levels assess the reliability of the findings across alternative measurements. Social and institutional characteristics are explored to evaluate alternative explanations in policing efforts. The article presents four decades of census data for municipalities in metropolitan areas. The central finding is that unequal levels of policing are prevalent across American municipalities. An additional finding is that social and institutional contexts affect policing, based on a pooled time‐series analysis of municipal governments. Although its main contribution is to local public economies research, the research also integrates the social and institutional literatures to identify factors in the allocation of resources to policing. 相似文献
