Japan passed its Child Abuse Prevention Act on 20 November 2000. In these early years following the passage of this Act, it is especially important to attempt to define what constitutes child abuse. Definitions and practical responses may be coloured by perceptions of service providers, and since professional culture is believed to influence individuals, this study compared the perceptions of (a) social workers, (b) physicians, (c) lawyers, and (d) the general public. Results suggested less disagreement in perceptions than was anticipated. When differences were observed, they were correlated more frequently with age and gender rather than with profession. 相似文献

This paper studies the impact of logistics performance on global bilateral trade. Taking a supply chain perspective, logistics performance refers to cost, time, and complexity in accomplishing import and export activities. We draw on a data set compiled by the World Bank containing specific quantitative metrics of logistics performance in terms of time, cost, and variability in time. Numerous researchers have shown that logistics performance is statistically significantly related to the volume of bilateral trade. Our research calibrates the impact of specific improvements in logistics performance (time, cost, and reliability) on increased trade. Our findings can spur public and private agencies that have direct or indirect influence over logistics performance to focus attention on altering the most relevant aspects of logistics performance to improve their country's ability to compete in today's global economy. Moreover, as our logistics metrics are directly related to operational performance, countries can use these metrics to target actions to improve logistics and monitor their progress. 相似文献

Public Choices Between Life Saving Programs: The Tradeoff Between Qualitative Factors and Lives Saved 总被引:1,自引:0,他引:1
In a telephone survey 1000 adults were confronted with pairs of life saving programs that differed in number of lives saved and asked which program in each pair they would choose to implement. Respondents were also asked to rate qualitative program characteristics on 10 point scales. For most respondents, lives saved are significant in explaining program choices, as are psychological risk characteristics. The rate of technical substitution between these characteristics and lives saved is, however, inelastic. It is noteworthy that for about 20 percent of respondents, choices among programs appear to be insensitive to lives saved. 相似文献

Demand for air travel is projected to increase in the upcoming years, with a corresponding influence on emissions, air quality, and public health. The trajectory of health impacts would be influenced by not just emissions growth, but also changes in nonaviation ambient concentrations that influence secondary fine particulate matter (PM2.5) formation, population growth and aging, and potential shifts in PM2.5 concentration‐response functions (CRFs). However, studies to date have not systematically evaluated the individual and joint contributions of these factors to health risk trajectories. In this study, we simulated emissions during landing and takeoff from aircraft at 99 airports across the United States for 2005 and for a 2025 flight activity projection scenario. We applied the Community Multiscale Air Quality (CMAQ) model with the Speciated Modeled Attainment Test (SMAT) to determine the contributions of these emissions to ambient concentrations, including scenarios with 2025 aircraft emissions and 2005 nonaviation air quality. We combined CMAQ outputs with PM2.5 mortality CRFs and population projections, and evaluated the influence of changing emissions, nonaviation concentrations, and population factors. Given these scenarios, aviation‐related health impacts would increase by a factor of 6.1 from 2005 to 2025, with a factor of 2.1 attributable to emissions, a factor of 1.3 attributable to population factors, and a factor of 2.3 attributable to changing nonaviation concentrations which enhance secondary PM2.5 formation. Our study emphasizes that the public health burden of aviation emissions would be significantly influenced by the joint effects of flight activity increases, nonaviation concentration changes, and population growth and aging. 相似文献

This study sought to examine the association between adolescents’ relationship with family and school and depressive symptoms
across ethnic/racial groups (White, Black, Hispanic, and Asian), and to test potentially unique explanatory power in youth–family
relationship versus youth–school relationship, in a sample of 4,783 adolescents. Depressive symptoms were assessed with a
19-item, modified Center for Epidemiologic Studies-Depression Scale (CES-D). The results indicated that youth–family relationship
and youth–school relationship were significant predictors of adolescent depression. However, the findings of the study indicated
that unique contributions by youth–family relationship and youth–school relationship were different by racial/ethnic groups.
These findings elucidate protective factors for adolescent depression and highlight the importance of cultural context of
each racial/ethnic group. 相似文献

Guided by a risk and resilience framework, this study used a prospective longitudinal, multiple‐reporter design to examine how social support from a mother figure during pregnancy interacted with Mexican‐origin adolescent mothers' self‐esteem to inform their parenting efficacy when their children were 10 months old. Using reports of perceived social support by adolescent mothers (Mage = 16.24, SD = 0.99) and their mother figures (Mage = 40.84, SD = 7.04) in 205 dyads, and controlling for demographic factors (i.e., adolescent age, adolescent nativity, family income, mothers' educational attainment, adolescent – mother coresidence) and adolescents' social support from a significant other, the findings indicated that social support during pregnancy was positively associated with adolescent mothers' future parenting efficacy when adolescent mothers had relatively lower self‐esteem. The findings were consistent for adolescents' and mothers' reports and emphasize the value of social support from a mother figure among adolescent mothers with lower self‐esteem. Implications for interventions are presented. 相似文献

This article examines how cultural contexts influence the demonstration of resilient behaviors of women senior managers in large organizations. We compare the experiences of Malaysian and Australian women overcoming key challenges and obstacles in their career journeys by engaging in the resilience strategies of network leveraging, learning, and adaptability. Our findings reveal the unique, complex, and contextual nature of career resilience, and show how resilience can be demonstrated, often differently, across culture and context. Our study adds to the existing body of literature in the areas of careers, gender in the workplace, and resilience, by highlighting how senior women sustain and navigate their career paths within the constraints of their socio-cultural contexts. Practical and scholarly implications are discussed. 相似文献

Partant de la matière de ce numéro spécial, les auteurs mettent en évidence les grands thèmes de recherche sur l'avenir du travail. Ils décrivent les mutations accélérées du monde du travail qui offrent des possibilités de croissance génératrice d'égalité, mais avec le risque de mal gérer le changement technique, les inégalités (en insistant sur le caractère intersectionnel et persistant des inégalités entre hommes et femmes), les chaînes d'approvisionnement mondiales et les nouvelles possibilités de dialogue social. Partant, ils formulent des recommandations pour renforcer la protection des travailleurs et les institutions qui les représentent, revoir les cadres réglementaires et les systèmes fiscaux, et enfin assurer des transitions équitables. 相似文献

The current study utilized an ecological framework to examine the longitudinal interrelations among Latino adolescents’ (N = 323) cultural orientation (i.e., ethnic identity and enculturation), familial ethnic socialization experiences, and generational status. Findings indicated that ethnic identity and enculturation were both predicted by adolescents’ generational status, although some of these relations were indirect via the relation between generational status and familial ethnic socialization. Findings underscore the importance of examining the dimensions of cultural orientation independent of one another and considering the central role of familial socialization practices in these processes. Moreover, the current work provides direction for further theoretical work to advance our understanding of the unique aspects of cultural orientation. 相似文献
