Traditional explanations of delinquency have mostly focused on male offending. While men were the primary subjects of criminological research as well as the central focus of the justice system, gender was rarely explicitly examined, and consequently, girls often went unnoticed. Today, however, female juvenile offenders' visibility both in research and in the system has changed. This essay reviews feminist theorizing of girls' delinquency, with a concentrated focus on the 'pathways' perspective; the scope of girls' lawbreaking; and their historical and contemporary experiences inside and outside the juvenile justice system. This essay concludes with an examination of two promising girl-specific juvenile justice initiatives. 相似文献

The major tasks of adolescence: Implications for transition planning with youths with cerebral palsy
Adolescents with cerebral palsy are presented with unique challenges as they make the transition to adulthood. There are a number of considerations that need to be addressed in a collaborative manner by rehabilitation professionals, educators, parents, and adolescents to facilitate the transition process. This article (a) explores the challenges that youths with cerebral palsy encounter as they attempt to accomplish the developmental tasks of adolescence and (b) discusses how those tasks can be integrated into transition planning. An overview of the medical aspects of cerebral palsy is also provided. 相似文献

The purpose of this study was to evaluate the effects of a 24-month moderate-intensity resistive-training intervention on strength and function in older adults. A repeated-measures experimental research design was employed as a sample of 55 apparently healthy, older, community-dwelling volunteers (30 exercisers- 25 women and 5 men; 25 comparisons- 16 women and 9 men) were evaluated for strength of 5 muscle groups that influence lower extremity movement and physical function. Strength and function were evaluated at 6-month intervals. The findings from this study indicate that a moderate-intensity resistive-training program increases strength in older adults and that the strength benefits are retained for the duration of the intervention. Furthermore, a long-term strength-training program can increase independent-function skills in older adults and might therefore aid in prolonging functional independence. 相似文献

In this study we developed a methodology that associated land cover categories to aerial photographs. We selected 4, 42-mile (10 km2) study sites within metropolitan Tucson, Arizona for our pilot study. Land uses within these sites covered the range of landscapes found within Pima County, Arizona, although not necessarily in proportions representative of the metropolitan area. We designated land cover categories within the pilot sites based on recent (March, 1990) aerial photographs and developed a geographical information system (GIS) database of these land cover categories. We measured vegetation attributes on randomly selected samples within each land cover category and classified vegetation occurring on specific land cover categories according to the Brown et al. (1979) system. Our land cover classification system was nominal with a hierarchical structure, facilitating organization and providing flexibility for adding new categories.Our results showed that although neighborhood parks contained the greatest vegetated areas within our four study plots, very low density housing (4 acres/house), rivers whose banks were partially stabilized, naturally occurring washes (with no bank stabilization), and natural open space contained the highest percentage of native vegetation. Within our four study sites, low density housing (4 acres/house), rivers with partially stabilized banks, naturally occurring washes (no bank stabilization), and natural open space land cover categories contained the most area that was covered with vegetation providing escape cover. 相似文献

In 2021, the Biden Administration issued mandates requiring COVID-19 vaccinations for U.S. federal employees and contractors and for some healthcare and private sector workers. These mandates have been challenged in court; some have been halted or delayed. However, their costs and benefits have not been rigorously appraised. This study helps fill that gap. We estimate the direct costs and health-related benefits that would have accrued if these vaccination requirements had been implemented as intended. Compared with the January 2022 vaccination rates, we find that the mandates could have led to 15 million additional vaccinated individuals, increasing the overall proportion of the fully vaccinated U.S. population from 64% to 68%. The associated net benefits depend on the subsequent evolution of the pandemic—information unavailable ex ante to analysts or policymakers. In scenarios involving the emergence of a novel, more transmissible variant, against which vaccination and previous infection offer moderate protection, the estimated net benefits are potentially large. They reach almost $20,000 per additional vaccinated individual, with more than 20,000 total deaths averted over the 6-month period assessed. In scenarios involving a fading pandemic, existing vaccination-acquired or infection-acquired immunity provides sufficient protection, and the mandates’ benefits are unlikely to exceed their costs. Thus, mandates may be most useful when the consequences of inaction are catastrophic. However, we do not compare the effects of mandates with alternative policies for increasing vaccination rates or for promoting other protective measures, which may receive stronger public support and be less likely to be overturned by litigation. 相似文献
