Sexual assault survivors often feel traumatized by the care received in traditional hospital emergency departments. To address these problems, Sexual Assault Nurse Examiner (SANE) programs were created to provide comprehensive medical care, crisis intervention, and forensic services. However, there is limited research on the actual experiences and emotional impact of sexual assault survivors who seek treatment from SANEs. This qualitative study examined twenty rape survivors' experiences with forensic nurse examiners of a Midwestern SANE program. Findings suggest that SANEs provided survivors with care and compassion, clear explanations, and choices. Taken together, these positive experiences were perceived as "humanizing". However, some survivors perceived forensic nurses as hurtful when they were not provided with choices, explanation, and/or acted cold and distant. Implications for future research on SANE care and practice are discussed.  相似文献

Anthropologists frequently encounter cases in which only partial human remains are recovered. This study reports how the percentage of the body recovered affects identification (ID) rates and cause and manner of death determination. A total of 773 cases involving anthropology consults were drawn from the New Mexico medical examiner's office (1974-2006). Results indicate a significant correlation between body percent recovered and ID rates, which ranged from 89% for complete bodies to 56% when less than half the body was present. Similar patterns were evident in cause/manner determination, which were the highest (83% and 79%, respectively) in complete bodies but declined to 40% when less than half the body was found. The absence of a skull also negatively impacted ID and ruling rates. Findings are compared with general autopsy ID rates (94-96%) and cause/manner determination rates (96-99%) as well as prior published rates for individual casework and mass death events.  相似文献

This paper reports the results of a series of experiments carried out to determine the precision of soil trace comparisons based on elemental peak height ratios determined by energy-dispersive X-ray analysis (EDXRA) in a variable pressure scanning electron microscope (VP-SEM). Experiments were conducted on 'bulk' soil aggregates, ground powders prepared from the <150 microm soil fractions and on smears of both the bulk soil and <150 microm material placed on cotton cloth. X-ray count data were obtained using area scans and spot analyses at different magnifications. The effects on elemental peak height ratios of varying the SEM chamber pressure, beam spot size, emission current and accelerating voltage were also examined. The peak height ratios for oxygen, silicon, aluminium, potassium, calcium and iron were found to show little variation as a function of chamber pressure, spot size and emission current over the ranges examined, but a strong dependency on accelerating voltage was observed. Within-sample variation in results, expressed by the percentage coefficient of variation, was found to be lowest for area scan analyses of the ground <150 microm fractions and greatest for the spot analyses of the bulk soil aggregates and the <150 microm fractions. We conclude that comparison of elemental peak height ratios determined by EDXRA can be a useful tool for rapid screening of soil samples, especially when combined with investigation of other attributes of the soil traces such as colour, fabric and the composition, shapes and surface textures of individual particles or aggregates within the soil traces. If sufficient material is available and can be readily separated without contamination or loss, higher resolution and more precise elemental data should be obtained by methods such as inductively coupled plasma atomic-emission spectrometry (ICP-AES) or mass-spectrometry (ICP-MS).  相似文献

The new and rapidly changing environment of development administrators includes (1) the emergence of a world society of interdependent nations, (2) a rapid and confusing technological and scientific revolution, (3) the expansion of service societies in industrialized countries, (4) new major alternatives for war, neocolonialism, despotism and materialism, and (5) development problems of ascending complexity and difficulty.Post-industrial beginnings in modern management arise from a background of management thought and technique in agriculturla epochs and the more recent industrial revolution. They encompass computer technology; operations research; systems approaches, including systems engineering, management information systems, and general systems research; cost-effectiveness analysis and PPBS; social indicators; and futurecasting. Their development has contributed to a growing gulf between technique and capability, to a triumph of technique over strategy and a retreat from human values.Attention is directed to specific strategies and tactics of introducing modern management techniques in developing nations. The efforts to do this during the 1960 Development Decade are reviewed. The prospects for the 1970's are previewed, and suggestions offered for problem area task forces and the expansion of U.N. activities in advancing, not merely diffusing, the current state of the art.Since the most significant modern management advances have been tactical, a dozen principles of strategic decisionmaking are suggested: (1) responsible decisionmaking, (2) the conflict essence of problems, (3) selectivity, (4) total system appreciation, (5) relative proportions, (6) sequential model-using, (7) problem interrelationships, (8) jointed incrementalism, (9) organized and unorganized interests, (10) the emotional basis of rational action, (11) investment in future capabilities, and (12) power mobilization and use.The paper ends by raising vital questions on the improvement of managerial values. This is done by specific proposals for a code of managerial ethics and the formulation of more humanistic management goals.  相似文献

A sex offender program delivered in a medium-security prison followed 109 treatment completers and 37 noncompleters for 2 years after release. Noncompleters, those who refused treatment or dropped out, had 6 times the rate of sexual and violent reoffending relative to completers. Among those who completed the program, however, positive evaluations of treatment change, such as quality of disclosure and enhanced victim empathy, found in posttreatment assessments did not correlate with recidivism. Furthermore, completers did not differ in their rates of recidivism from pretreatment rates predicted by the Static 99, an actuarial measure of anticipated sexual and violent recidivism. We conclude that the program did not influence propensities for sexual and violent recidivism but rather served as a prolonged screening instrument for sex offenders whose failure to comply with treatment attendance predicted higher rates of recidivism.  相似文献
