The aim of the present epidemiological study was to investigate characteristics of assaults in the elderly aged 65 years and above from the perspective of the victim and perpetrator. This population-based study included 23,142 assaults (according to §§ 224/226 StGB of German criminal law) that were recorded in Bavaria, Germany, from 1999 to 2005. The population-based ratio of serious crimes of battery for the elderly in comparison with the reference population was markedly lower (0.10; 95% CI: 0.09-0.11) in suspects aged more than 65 years and 0.08 (95% CI: 0.07-0.09) for the injured above 65 years. Elderly perpetrators differed significantly concerning the manner of the assault (p < 0.001). They committed less crimes in urban areas (56.1% vs. 68.8%) and were victimized significantly more in rural areas (p < 0.001; 41.2% vs. 30.2%). Violence in the elderly differs from that of the younger population. Further research is warranted to establish prevention measures. 相似文献

The use of inductively coupled plasma-mass spectrometry (ICP-MS) in the study of gunshot residues (GSR) is relatively recent, and only a few studies have been published on the subject. In the present paper, this instrumental technique has been used to study the deposit pattern of the GSR around the bullet entrance hole, through the analysis of antimony (Sb), barium (Ba), and lead (Pb). The data obtained were used to establish a mathematical model for estimating the firing distance. Test shots using a 6.35-mm pistol were made against a target of cotton tissue, and the amounts of Sb, Ba, and Pb deposited in quadrangular pieces of the target, cut from 4 radial positions, were determined by ICP-MS. In these experimental conditions, it was possible to estimate the firing distance on the interval [20-80] cm. The best linear correlation between ln m and d, where m is the mass of Sb, Ba, or Pb in the samples, expressed in mug/g of target tissue, and d the firing distance, was obtained at radial distances between 3.5 cm and 4.5 cm from the entrance hole. The best regression curve which adjusted to the data was a linear multiple regression between the firing distance and the logarithm of the mass of each element: d = a + b(1)X(1) + b(2)X(2) + b(3)X(3), where X(1) = ln m (Sb), X(2) = ln m(Ba) and X(3) = ln m (Pb). The accuracy of firing distance estimation using only 1 or 2 elements was not significantly different from the one obtained with the 3 elements. 相似文献

This investigation intends to study materials and techniques used for biological evidence collection in sexual assault cases and is divided into two stages: in stage one, methods for biological evidence collection (the single swab (including three variants) and the “double swab technique”) were compared; in stage two, swabs’ component material was compared. The sampling was composed of 42 heterosexual couples who provided mock samples. The collection methods in which the whole swab is covered by evidence presented significantly better outcomes (p < 0.001), such as the “double swab technique.” Additionally, nylon swabs proved to present significantly better features regarding the capacity of sample elution, providing significantly higher amounts of DNA (p ≤ 0.034). This study provides guidelines for better collection of biological evidence regarding the collection method using a swab and the proper swab material to utilize. 相似文献

A Midwestern state’s child welfare agency contracted with a university to evaluate a 5-year Title IV-E Waiver Demonstration Project. As part of the process study, evaluators employed case study analysis to investigate Waiver knowledge and effects as reported by Regional and Executive Managers across 4 years of the demonstration period. Data from 78 interviews reveal enhanced levels of manager–evaluator rapport and integrated Waiver knowledge across years of data collection. This study highlights the value of middle managers as rich data sources, studying process through qualitative methods in child welfare evaluation, and how consistent relationships can support partnerships over time. 相似文献

Stigma as a barrier to employment: mental disability and the Americans with Disabilities Act 总被引:1,自引:0,他引:1
Scheid TL 《International journal of law and psychiatry》2005,28(6):670-690
In a controversial expansion of workplace civil rights, the 1990 Americans with Disability Act (ADA) extended anti-discrimination protection to individuals with "mental impairments." One of the most critical barriers to the employment of individuals with mental disabilities is the degree of social stigma such disabilities incur, and there is compelling evidence that employers have stigmatizing attitudes and have discriminated against those with mental disabilities. This study examines the role played by stigma in employers' response to the 1990 Americans with Disability Act (ADA). A stratified sample of one hundred ninety employers were surveyed in 1996-1997 in a major Southern metropolitan area. Telephone interviews were completed with one hundred seventeen employers (response rate of 61.6%). The article describes employers' experiences with employees with mental disabilities and accommodations, specific employment practices, and attitudes towards those with mental disabilities. Stigma played an important role in conformity to the ADA (operationalized as either hiring or having specific recruiting policies for hiring individuals with mental disabilities). Furthermore, employers expressing coercive (fear of a lawsuit) as opposed to normative (belief that it is the right thing to do) rationales for compliance were more likely to hold stigmatized attitudes. Employers' beliefs about mental disability form a crucial foundation for truly supportive work environments (those that value difference and diversity), and further research is needed to determine if over time the ADA is successful in changing attitudes as well as behavior. 相似文献

Positive psychologists found the increase of seven character strengths that encompass the so-called theological virtues, including hope and spirituality, in Americans after the September 11, 2001, attacks. Little is known about how they may affect post-September 11, 2001, mental health. Using multivariate analysis, this study investigated the relationship of hope and spiritual meaning with depression and anxiety in a sample of 457 students 3 months after September 11, 2001. Both characters contributed to lower levels of symptoms. In qualitative analysis, of 313 answers to an open-ended question regarding personal change, four categories emerged. The first three were consonant with other studies on posttraumatic growth (PTG), including changes in the self or behavior, relationships, and worldviews. The fourth category unique to September 11, 2001, was changes in political views. These findings offer further credence to the study of positive aspects resulting from violence-related trauma and highlight the needs for addressing the nature of traumatic events and PTG. 相似文献

The PowerPlex 16 BIO multiplex short tandem repeat (STR) system contains the 13 CODIS loci (FGA, TPOX, D8S1179, vWA, D18S51, D21S11, TH01, D3S1358, CSF1PO, D16S539, D7S820, D13S317, and DS5S818), plus two pentanucleotide repeat loci (Penta D and Penta E) and the sex-identifying locus. Amelogenin. The PowerPlex 16 BIO System is optimized for use with the Hitachi FMBIO gel imaging systems. A consortium of seven independent laboratories collaborated to perform the studies defined by the FBI standards for performing a developmental validation, including the evaluation of sample concordance, percent stutter determination, nonprobative casework, precision, sensitivity, mixture determination, effect of substrates, the impact of environmental insults, and species specificity. All samples tested for concordance were consistent except for one sample from the Virginia Division of Forensic Science database that displayed discordance at D13S317, a locus whose primer sequence was altered. Stutter values were comparable to those of other STR multiplex systems, the precision was comparable to other multiplexes analyzed by gel electrophoresis, the DNA profiles were unchanged by the substrate upon which the blood samples were placed, and the nonprobative casework samples re-typed for the PowerPlex 16 BIO System were consistent with previous typing results. When greater than 0.125 ng of DNA was placed into the PowerPlex 16 BIO System amplification reaction, a full profile was generated by all laboratories. The mixture study results were comparable to those reported for other multiplex systems, the environmental study demonstrated a loss of larger molecular weight loci when samples were incubated at elevated temperatures for a prolonged period of time, and the only notable cross species hybridization was observed with primate DNA samples. This extensive validation work performed demonstrates that the PowerPlex 16 BIO System provides STR data of a quality comparable with other PowerPlex STR multiplex kits as well as other widely used STR multiplexes and is thus suitable for evidentiary casework analysis as well as database sample profiling. 相似文献

This study examined the impact of the September 11 terrorist attacks on graduate and undergraduate students and the role of optimism in posttraumatic distress. A sample of 457 students who attended courses at three schools of social work (Nevada, Pennsylvania, and Washington) participated in the study. A quarter of them had a known person as an immediate victim of the attacks. Multivariate analysis showed that posttraumatic stress disorder symptom scores were positively related to personal loss and two types of previous trauma reactivated by the attacks, and levels of initial negative emotional response. Optimism and its interaction with personal loss were inversely associated with posttraumatic stress disorder symptom scores. 相似文献
