One hundred and twenty eight cases of shooting fatalities were investigated during an 11-year period. Of these 57% were homicidal shootings with 34% suicidal in nature. Only two suicidal fatalities were female. Analysis of the sites of entrance wounds confirmed the 'sites of election' in suicidal shootings, whilst homicidal wounds showed a much wider distribution. Multiple entrance wounds were seen in 42% of homicidal shootings. Injuries to hands were seen in 7 homicidal fatalities. 相似文献

This paper describes the recovery and identification of crew members lost during a collision at sea. On 9 February 2001, south of Honolulu, Hawaii, the Japanese fishing training boat, Ehime Maru was struck by the USS Greeneville (SSN 772), a Los Angeles-class fast attack submarine. Witnesses estimate that the vessel sank within 5-10 min after the collision. Nine of the 35 crew members remained unaccounted for after rescue procedures were completed. The U.S. Navy attempted the unprecedented procedure of moving the boat from a depth of 610 m (2000 ft) into shallower waters so that the missing could be located and recovered. Eight of the nine crew members were recovered and identified by their dental records. 相似文献

Photodegradation and laser desorption mass spectrometry (LDMS) is a powerful combination of methods capable of characterizing dyes found in pen inks. Rhodamine dyes in pens that contain red ink were analyzed directly from paper (no extraction step is necessary). Inks exposed to incandescent light form photodegradation products (compounds with lower molecular weights than that of the intact dye) and in some instances, photoproducts (compounds with higher molecular weights than that of the intact dye). The degradation products and photoproducts can be detected with LDMS, and the results can be used for dye identification. Advantages include: (1) the instrumental analysis takes less than a minute; (2) sample preparation is minimal; (3) LDMS is a minimally destructive technique; (4) incandescent light sources are inexpensive, safe to use, and readily available; and (5) isomeric dyes can be distinguished. 相似文献

The development of assisted reproductive technologies, including cryopreservation, or freezing, of embryos created through in vitro fertilization, has given rise to complex legal questions. Because cryopreservation permits indefinite storage of embryos, if couples fail to specify disposition directions, they may disagree regarding embryo treatment upon the occurrence of contingencies such as divorce. Few courts have resolved such disputes, and those that have appear to uphold the rights of the party seeking to prevent implantation in the absence of a written agreement specifying otherwise. In this Comment, Sara Petersen proposes that courts should draw upon contract law principles in determining whether the parties to such conflicts actually reached agreements regarding embryo disposition in the event of divorce. After analyzing existing precedent, the author assesses proposed approaches for deciding which party's interests should prevail and concludes that these methods are inherently ineffective. She then argues that, in an effort to preserve party expectations and to provide fair results, courts instead should examine whether the parties executed binding contracts or achieved mutual assent. Furthermore, she suggests that couples undergoing cryopreservation will be more likely to contemplate and to provide for various outcomes if they know that courts will look at evidence of their conversations and thought processes prior to cryopreserving their excess embryos. 相似文献

This study extends findings on community violence (CV) exposure in young adults by examining the prevalence, characteristics, and socioemotional effects related to hearing about violence. Surveys of lifetime CV exposure and socioemotional outcomes were completed by 518 male and female undergraduates completed and were divided into groups with high, moderate, or low scores on hearing. Of respondents, 97.8% reported hearing about violence at least once, with a substantial proportion hearing about different types of acts. Reportedly, the most frequent perpetrators were non-family members, the most frequent location was near home, and most incidents occurred within the past year. The high-scoring group reported significantly greater levels of depressed mood, posttraumatic stress symptoms, aggressive behavior, and interpersonal problems associated with personality disorders. Results extend previous findings on the unfortunate prevalence of violence exposure and its negative psychological effects in today's young adults and suggest that chronic exposure to hearing about violence can have deleterious repercussions. 相似文献

Not all the time … but mostly … is the outcome of collaboration across the genres of ethnographic research, and visual and performing arts. In exploring renewed methodologies for social research Maggie sought to develop a methodological model (ethno-mimesis) rooted in feminist thought and practice, that represented in visual artistic forms the multiple standpoints of women working in prostitution. Ethno-mimesis is a combination of ethnographic research and the representation of this work in visual/artistic form. Introduced by a mutual friend in 1997 our collaborative work began with Sara reading and interpreting the ethnographic work with a view to developing a performance text, as an exemplar of ethno-mimesis. In the collaborative work presented here the hybrid texts that emerge are an outcome of the inter-relationship between ethnographic research and the re-presentation of women's life stories through live art forms – video, and two movement based performances. Through this work we hope to reach a wider audience, beyond academic communities, facilitating understanding, interpretation and maybe even action/praxis in relation to prostitution as a social issue. In representing ethnographic data in artistic form it is hoped that we can access a richer understanding of the complexities of women's lived experiences that can throw light on broader social structures and processes. Such hybrid work may also help audiences to see that women working in prostitution are ordinary women; and that ‘prostitutes’ are indices for all women. 相似文献
