Advances in genomic science are attracting the interest of the U.S. military for their potential to improve medical care for members of the military and to aid in military recruitment, training, specialization, and mission accomplishment. While researchers have explored the ethical, legal, and social issues raised by the use of genomic science in a wide variety of contexts, there has been virtually no examination of these issues in connection with the use of genomics by the military. This article identifies potential uses of genomic science by the military, proposes an applicable ethical and legal framework, and applies the framework to provide ethical and legal guidance for military decision-makers.  相似文献

This research demonstrates the value of laser scanning confocal microscopy (LSCM) as a research tool in osteological studies, and diagenetic studies in particular. LSCM combines properties of light and scanning electron microscopy using laser light to excite fluorophores throughout the z-axis, developing a 3-D image. Using differential staining and selecting for specific wavelengths of light, one can image targeted materials. This research is divided into two parts: visualizing bone structures such as proteins and their decompositional products and visualizing diagenesis. Part one of this study utilized pig bones as a means of testing the overall ability of LSCM to fluoresce bone. Twenty-three samples were imaged, including 13 samples from a decompositional study conducted 5 years previous, and 10 “fresh” samples collected from a commercial butcher. This part of the study determined that protein and organic components of the bone could be fluoresced and diagenetic alteration could be imaged. The second part of the study used human samples as a means of imaging and mapping diagenetic alterations. The second part of the study used 13 samples, including 4 clinical, 7 ancient, and 2 modern controls. The pig study used Basic Fuchsin and SlowFade Gold stains, while the human study used toluidine blue. Images were also taken with unstained elements. The results of the non-human study found that a fresh bone fluoresced differently than that of a 5-year subset, while the results of the human study confirmed these findings and determined that the bone diagenesis can be mapped using LSCM.  相似文献

Analysis of neonaticide cases from a law enforcement perspective is virtually non-existent in the research literature. Nonetheless, law enforcement and prosecutors face unique challenges when investigating and prosecuting neonaticide; and a specialized, informed approach is necessary. By highlighting the crime scene characteristics and autopsy findings of 55 neonaticide victims, the authors hope to assist the law enforcement and legal communities in their neonaticide investigations. Specifically, this article clarifies how neonaticide occurs by chronologically examining the pregnancy, the birth and death of the infant, the subsequent crime scene (or scenes) and the pathological findings. The article also highlights the potential challenges that may arise during investigation and prosecution of these cases in addition to providing the forensic community with recommended investigative techniques.  相似文献

Household formation patterns have been adduced in recent years by historians and other social scientists to account for the economic development of western Europe. The so-called European Marriage Pattern, which prevailed throughout northwest Europe, is viewed as having been particularly conducive to early industrialisation and economic growth. But to what extent were household formation systems exogenous to the broader economic and social context in which they were located? Evidence from nineteenth-century Russia indicates that family systems were influenced by the same variables that determined the shape of the local economy; they were part of a complex web of institutions and thus cannot be viewed as independent determinants of economic development.  相似文献

Changes in federal government relations with First Nations and Métis in Canada have been described as shifting over time, from fur trade colonialism, to welfare colonialism, to neoliberal partnerships. Acknowledging changes and continuities in Aboriginal peoples–state relations over time, this article examines the effects of recent policies that emphasize private–public partnerships for economic development on Indigenous communities in northern Alberta. We argue that while the term ‘partnership’ connotes equality, cooperation, and consensus, the actual workings of partnerships are anything but equal, and the effects include fragmentation, competition, and lack of overall accountability. These outcomes work against the needs and aspirations of Indigenous communities.  相似文献

This study examines the effects of taphonomic processes on blunt force trauma (BFT) through an experimental study involving pig heads. Of particular concern is the possibility that taphonomic changes can create pseudo-trauma and/or conceal evidence of actual trauma. BFT was inflicted on 10 pig skulls using a hammer. The skulls were subsequently exposed to the environment for 12 months. Seven taphonomic changes were evaluated: the freeze-thaw cycle; rodent gnawing; carnivore scavenging; presence/weight of soil; presence/weight of rain and snow; movement/displacement of bones; and discoloration due to sun bleaching and grass staining. Taphonomic effects varied between cancellous, compact, fresh, and degreased bone. Freezing and thawing, exposure to rain and snow, movement of the skulls, and soil erosion altered and, in some cases disguised, pre-existing trauma. Rodent and carnivore activity did not obliterate evidence of BFT. Recommendations for evaluating BFT on remains affected by taphonomic processes are presented. As each taphonomic process outlined by this study has the potential to disguise antemortem injury, the authors propose that one must carefully examine large, circular openings in the skull that may represent the remnant evidence of BFT.  相似文献

Abstract: The frontal sinuses are known to be unique to each individual; however, no one has tested the independence of the frontal sinus traits to see if probability analysis through trait combination is a viable method of identifying an individual using the frontal sinuses. This research examines the feasibility of probability trait combination, based on criteria recommended in the literature, and examines two other methods of identification using the frontal sinuses: discrete trait combinations and superimposition pattern matching. This research finds that most sinus traits are dependent upon one another and thus cannot be used in probability combinations. When looking at traits that are independent, this research finds that metric methods are too fraught with potential errors to be useful. Discrete trait combinations do not have a high enough discriminating power to be useful. Only superimposition pattern matching is an effective method of identifying an individual using the frontal sinuses.  相似文献

Parochial schools are assumed to provide better social and academic experiences; however, few studies account for selection bias when comparing with public schools. This study contrasted public versus parochial schools using propensity score matching across a range of outcomes (e.g., perceptions of school, emotional symptoms, substance use, bullying). Using a sample of 58 public and 5 parochial high schools, the nonmatched analyses suggested a significant advantage for parochial schools students (e.g., better on 23 of 32 indicators). However, the propensity score matched analyses revealed nine differences (e.g., weapon carrying, smoking), two of which (i.e., stress and cyberbullying) favored public schools. While at first glance parochial schools generally appear to be healthier and safer learning environments, accounting for selection bias, the gap was narrowed. Students in parochial schools may struggle with issues related to social, emotional, and behavioral health risk, and thus prevention programs should also be implemented in these settings.  相似文献

The Trade and Tariff Act of 1984 includes a new measure, country graduation, designed to shift a greater share of the benefits of the US Generalized System of Preferences (GSP) from the more advanced developing countries to poorer beneficiary countries. This note presents estimates of the effects of graduating Hong Kong, South Korea, Singapore and Taiwan on the poorest countries of Africa. Our results show that the removal of these four countries will do little to increase the GSP benefits of the African beneficiary countries.  相似文献

Raman spectroscopy has found increased use in the forensic controlled substances laboratory in recent years due to its rapid and nondestructive analysis capabilities. Here, Raman spectroscopy as a screening test for methamphetamine in clandestine laboratory liquid samples is discussed as a way to improve the efficiency of a laboratory by identifying the most probative samples for further workup among multiple samples submitted for analysis. Solutions of methamphetamine in ethanol, diethyl ether, and Coleman fuel were prepared in concentrations ranging from 0.5% to 10% w/v, and Raman spectra of each were collected. A concentration‐dependant Raman peak was observed at 1003 per cm in each solution in 4% w/v and greater solutions. Case samples were analyzed and also found to reliably contain this diagnostic peak when methamphetamine was present. The use of this diagnostic indicator can save the forensic controlled substances laboratory time and materials when analyzing clandestine laboratory liquid submissions.  相似文献
