To examine correlates of the speed at which female soldiers carrying loads could cover 3.2 km on foot and traverse an obstacle course, 12 volunteers (mean +/- SD: 25.3 +/- 6 years, 166 +/- 7 cm, 61.3 +/- 7 kg) were timed over 3.2 km while carrying loads of 14, 27, and 41 kg, and while traversing an obstacle course with the two lighter loads. Pearson correlations showed that absolute VO_[2 max] and 3.2 km run time without a load were the best predictors of 3.2 km load carriage time for all loads. Also, larger subjects with greater muscle mass were able to carry the heaviest load faster than smaller, less muscular subjects, likely because the 41 kg load represented a smaller percentage of the former's bodyweight. Maximum number of sit-ups and push-ups, composite score of the Army Physical Fitness Test as well as body height were positively correlated with the speed at which some course segments were traversed. 相似文献

Over half of the people who become disabled whilst employed are thought to be pressured into leaving their job. This study investigates the experience of involuntary retirement/redundancy due to disability. Three researchers who had all experienced such involuntary job loss were trained to conduct the research. Semi-structured interviews were designed and conducted by disabled researchers. The training of the researchers enabled them to successfully conduct a research project. The results of the project show the impact of involuntary job loss due to disability to be considerable. This study would suggest that government reforms to create new opportunities for disabled people of a working age are well overdue. Although there were some problems experienced with the amount of training required and the lack of objectivity, training disabled researchers to conduct research proved to be a valuable experience for both the researchers and the facilitators. 相似文献

Although national level studies in the United States and Canada find that extreme partner age discrepancy is a risk factor for intimate partner homicide in opposite-sex couples, these studies carry two caveats: They are limited to cohabiting marital or common-law couples and they are not detailed enough to explore alternative explanations for the age discrepancy-homicide risk association. Using the Chicago Homicide Dataset, which includes all homicides that occurred in Chicago from 1965 to 1996, we analyze the 2,577 homicides in which the victim was killed by a current or former legal spouse, common-law spouse, or heterosexual boyfriend or girlfriend, and in which the woman was at least 18 years of age. Within each of 14 categories of couple age discrepancy, we estimate the population of intimate heterosexual couples and calculate the population-based risk of homicide. The results replicate national level findings showing that the risk of intimate partner homicide is considerably elevated for couples with a large discrepancy between their ages-where the man is at least 16 years older than the woman or the woman is at least 10 years older than the man. This risk pattern occurs regardless of whether the man or the woman was the homicide offender. We then investigate whether the link between partner age discrepancy and homicide risk is explained by the offender's arrest record. Results show that the higher risk of intimate partner homicide for age discrepant couples is robust, and does not depend on the previous arrest record of the offender. Discussion addresses other possible explanations for the increased risk of partner homicide for age discrepant couples, and the practical implications of these findings. 相似文献

ABSTRACTThis study evaluated the success of researcher-generated recruitment, enrollment, data collection, and safety protocols for field research with victims of elder abuse and neglect (EAN) identified from police incident reports in terms of their success including cost-effectiveness, ability to generate a representative sample, and safety. After reviewing 492 police incident reports involving victims age 65 years or older to identify cases of EAN 62 victims were identified. Mail, phone, and in-person recruitment strategies were used. After 259 recruitment attempts, 52 (84%) eligible victims were contacted, of which 24 (46%) consented to participate. Phone calls were the least expensive mechanism to produce a successfully enrolled participant. Findings from a regression show completion of a research interview could not be predicted by victim, suspect, or offense characteristics, indicating that the recruited victims likely represent the population they were drawn from. No safety or adverse events occurred. 相似文献

In this article we demonstrate that Yanyuwa people have detailed biological knowledge of their northern Australian environment, which is culturally defined and embedded within their relationships to country, resources and each other. Through a case study of the impact of Bufo marinus (cane toads) on Yanyuwa culture and everyday life, we argue that Aboriginal management strategies and Aboriginal peoples’ intimate knowledge of species and environment need to be understood as both legitimate and fundamental when engaging in management initiatives in Australia. We demonstrate that for Yanyuwa people emotional engagement with their environment is underpinned by a morality of social and environmental relations and that ‘memory’ is pivotal to this engagement. We conclude by briefly delineating how the adoption of a ‘moral ecology’ perspective goes some way to addressing issues pertinent to discursive encounters at cultural management frontiers. 相似文献
