Expert testimony on rape trauma syndrome has been used in sexual assault cases to corroborate the victim's complaint and to educate the jury. One of the primary arguments against the admissibility of this testimony is that it is not helpful because most jurors are adequately informed about rape and rape victim behavior. To test this assumption, a Sexual Assault Questionnaire (SAQ) was administered to experts on rape and post-traumatic stress disorder (PTSD) and two nonexpert comparison groups. Results indicated that the nonexperts were not well informed on many rape-related issues and were significantly less knowledgeable than the expert groups. The data also showed considerable consensus among the experts about the current scientific database on rape trauma. The implications of these results for the use of expert psychological testimony on rape trauma syndrome in court are discussed.  相似文献

The 1990s witnessed Supreme Court decisions in both Canada and the United States on issues of competence that went against longstanding case law, psychological research, and common sense. These decisions held that there is to be one standard for all types of criminal competencies. The present research attempts to investigate whether this is an appropriate assumption and thus tests whether there are one or more constructs that underlie different types of competence. Two divergent types of competence were examined, competence to stand trial (both Canadian and American conceptualizations) and competence to consent to treatment, to determine if these different types of competence share a common underlying construct. Confirmatory factor analysis was used to test this question and results indicate that there is a common construct that underlies different types of competence.  相似文献

Childhood abuse and other developmentally adverse interpersonal traumas may put young adults at risk not only for posttraumatic stress disorder (PTSD) but also for impairment in affective, cognitive, biological, and relational self-regulation ("disorders of extreme stress not otherwise specified"; DESNOS). Structured clinical interviews with 345 sophomore college women, most of whom (84%) had experienced at least one traumatic event, indicated that the DESNOS syndrome was rare (1% prevalence), but DESNOS symptoms were reported by a majority of respondents. Controlling for PTSD and other anxiety or affective disorders, DESNOS symptom severity was associated with a history of single-incident interpersonal trauma and with more severe interpersonal trauma in a dose-response manner. Noninterpersonal trauma was associated with elevated prevalence of PTSD and dissociation but not with DESNOS severity. Study findings indicate that persistent posttraumatic problems with self-regulation warrant attention, even in relatively healthy young adult populations.  相似文献

The increase in both automation and precision in the analysis of geological materials has had significant impact upon forensic investigations in the last 10 years. There is however, a fundamental philosophical difference between forensic and geological enquiry. This paper presents the results of forensic geoscientific investigations of three cases of wildlife crime. Two cases involve the analysis of soils recovered after incidents of illegal badger baiting in the United Kingdom. The third case involves the illegal importation of Eleonora's Falcon (Falco eleonorae) into the United Kingdom from the Mediterranean. All three cases utilise the analysis of soils by a variety of physical, chemical and biological techniques. These involve mineral and grain size analyses, cation and anion compositions, pH, organic content and pollen analysis. The independent analysis undertaken by specialists in each of these three main fields conclude firstly, that there is a significant similarity between sediments taken at the crime site at both badger setts and with sediments recovered from various spades, shovels and clothing belonging to suspects and secondly, that the soils analysed associated with the removal of the falcon eggs in the Mediterranean contained characteristics similar in many respects to the soils of the breeding areas of F. eleonorae on the cliffs of Mallorca. The use of these independent techniques in wildlife crime detection has great potential given the ubiquitous nature of soils and sediments found in association with wildlife sites.  相似文献

Haplotype data were obtained from a sample of 777 unrelated male individuals from Antioquia Department (Colombia), for eight Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393). A total of 442 different haplotypes were identified of which 334 were represented only once in the database and the most frequent haplotype was found in 32 individuals. A high haplotype diversity was found (99.45%). Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of lberian origin.  相似文献

Many of the federal and state programs that provide income security to U.S. families have their roots in the Social Security Act (the Act) of 1935. This Act provided for unemployment insurance, old-age insurance, and means-tested welfare programs. The Great Depression was clearly a catalyst for the Social Security Act of 1935, and some of its provisions--notably the means-tested programs--were intended to offer immediate relief to families. However, the old-age insurance program-the precursor to today's Old-Age, Survivors, and Disability Insurance, or Social Security, program-was not designed specifically to deal with the economic crisis of that era. Indeed, monthly benefit payments, under the original Act, were not scheduled to begin until 1942. In addition, from the beginning, the Social Security program has embodied social insurance principles that were widely discussed even before the onset of the Great Depression. The first four decades of the Social Security program were, in general, ones of expansion. In fact, the program was expanded even before it became truly operational. In 1939, amendments added child, spouse, and survivor benefits to the retirement benefits authorized by the 1935 Act. Those amendments also allowed for monthly benefits to begin in 1940. Although the program was not changed substantially during the war years and the initial postwar period, the 1950s were a transformational decade in the program's history: benefit amounts were increased substantially, coverage under the program became close to universal, and a new disability insurance benefit was offered. The 1960s witnessed additional growth in Social Security, but the most important development in social insurance occurred in health insurance, with the creation of the Medicare program in 1965. Legislative actions in the 1970s had profound effects on the Social Security program and, indeed, set the stage for many of today's reform debates. Large benefit increases, a new benefit formula that was erroneously generous, and other changes in the early 1970s created a situation in which annual program costs, as a share of gross domestic product, increased during a 12-year period from about 3 percent to 5 percent. In 1977, amendments to the Act corrected the flawed benefit formula and made other changes in the financing of the system to shore up the program. Thus, the 1970s represent a watershed in the program's history-program growth gave way to increasing concerns about the program's finances. Those concerns were reflected in the amendments to the Act in 1983, which were the last major changes to the program. These amendments, based largely on recommendations from a commission chaired by Alan Greenspan, adjusted benefits and taxes to address pressing near-term financing problems faced by the system. Although the Greenspan Commission focused to a large extent on short-range issues, the resulting reforms have generated large surpluses in the program and the buildup of a substantial trust fund. However, the looming retirement of the baby boomers and several other demographic factors will, according to projections, result in the exhaustion of the trust fund by 2042.  相似文献
