While researchers have found that African American youth experience higher levels of juvenile justice involvement at every system level (arrest, sentencing, and incarceration) relative to their other ethnic counterparts, few studies have explored how juvenile justice involvement and number of contacts might be correlated with this broad range of problems. A convenience sample of 638 African American adolescents living in predominantly low-income, urban communities participated in a survey related to juvenile justice involvement. Major findings using logistic regression models indicated that adolescents who reported juvenile justice system involvement versus no involvement were 2.3 times as likely to report mental health problems, substance abuse, and delinquent or youth offending behaviors. Additional findings documented that the higher the number of juvenile justice system contacts, the higher the rates of delinquent behaviors, alcohol and marijuana use, sex while high on drugs, and commercial sex. These findings suggest that identifying and targeting youth who have multiple juvenile justice system contacts, especially those in low-resourced communities for early intervention services, may be beneficial. Future research should examine whether peer network norms might mediate the relationships between juvenile justice involvement and youth problem behaviors.  相似文献

Amid the rise of democratization movements since the 1980s, many governments in developing countries have proactively introduced the ideas of decentralization and devolution into the policy arena. In the pursuit of democratic planning processes where civil society is encouraged to be a part of the formal decision-making system, articles advocating the empowerment of non-governmental organizations (NGOs) have been included into a series of legislations. This shift was soon reflected in housing development frameworks for the poor, leading to the formulation of a new approach called "enablement." The Philippines' experience for the last two decades follows this line of development. Filipino NGOs are now prescribed as a catalyst to add further dynamism to the improvement of substandard living environments. Empirical findings of this study exemplify that NGO empowerment has been increasingly accelerated by the combination of NGOs' self-endeavors and governments' initiatives. By utilizing the paradigm shift under the enablement approach, NGOs are engaged in the attempt of alliance-formation and network-building to expand their influence. Contrary to ideals, however, NGO empowerment may reveal some adverse effects such as excessive dependency on NGOs and distorted representation by NGOs. Moreover, the professionalization of NGOs is an additional factor which generates hierarchization at the grass-roots level. This study suggests that further research analyze the depth and width to which NGO empowerment has been penetrated in order to precisely capture the processes and consequences resulting in disempowerment.  相似文献

To understand differences in labor market outcomes between genders, economists must examine a complex array of potentially significant factors, such as institutional context, productivity differences, child-bearing and home production, and bargaining behavior. Many of these factors are not well captured by standard data sources. We use a new survey of academics in Japan to better understand the sources of gender pay differences. We find a 6% pay gap which persists when we control for research productivity, despite an institutional context shaped by explicit salary tables. We do not find a motherhood wage penalty, and the gender salary we document is not affected by differences in outside job offers.  相似文献

The present study examined the influence of culturalbackground on the experience of loneliness. Threehundred and seventy five participants from NorthAmerica and 375 from Croatia volunteered to answer an82 item questionnaire which examined the quality oftheir loneliness experiences. The factors whichcomprise the experience of loneliness are Emotionaldistress, Social inadequacy and alienation, Growth anddiscovery, Interpersonal isolation, andSelf-alienation. Results indicated that culturalbackground, indeed, affects the experience ofloneliness. North Americans scored higher on all fivefactors, and a similar trend was evident when men andwomen were compared across cultures.  相似文献

This paper refreshes an empirical examination ofthe garbage can model, particularly in a sample drawnfrom Japanese firms. The garbage can model oforganizational decision making was originally developed by Cohen, March, and Olsen (1972) to describeorganized anarchy. This paper incorporates twomethodologies in an attempt to both validate and extendthe garbage can model: Simulation is first used togenerate a research hypothesis, then several surveys areconducted to test that hypothesis and to empiricallydevelop an ex-post model of decision ambiguity, flight,and anarchy. The data support our hypothesis and we find out new conditions of ambiguity:(i) fluid participation, (ii) divorce of solution fromdiscussion, and (iii) job performance rather thansubjective assessments, which are clearly related to the simulation assumption of our single garbagecan model. By using our new conditions of ambiguity, wedevelop a measure of degree of anarchy, and theregression analysis indicates a linear relationship between the flight ratio and the degree ofanarchy.  相似文献

This article focuses on conceptual and methodological developments allowing the integration of physical and social dynamics leading to model forecasts of circumstance‐specific human losses during a flash flood. To reach this objective, a random forest classifier is applied to assess the likelihood of fatality occurrence for a given circumstance as a function of representative indicators. Here, vehicle‐related circumstance is chosen as the literature indicates that most fatalities from flash flooding fall in this category. A database of flash flood events, with and without human losses from 2001 to 2011 in the United States, is supplemented with other variables describing the storm event, the spatial distribution of the sensitive characteristics of the exposed population, and built environment at the county level. The catastrophic flash floods of May 2015 in the states of Texas and Oklahoma are used as a case study to map the dynamics of the estimated probabilistic human risk on a daily scale. The results indicate the importance of time‐ and space‐dependent human vulnerability and risk assessment for short‐fuse flood events. The need for more systematic human impact data collection is also highlighted to advance impact‐based predictive models for flash flood casualties using machine‐learning approaches in the future.  相似文献

We obtain first order asymptotic expansions for the distribution of the excess of a standard normal random walk over a curved boundary and the error probabilities of some repeated significance tests. The key step in the analysis is an asymptotic expansion for the conditional probability that the random walk has not crossed the boundary before the N step, given that it is near the boundary after the nth step.  相似文献

Background

Decreased fetal movements are associated with adverse perinatal outcomes, including stillbirth. Delayed maternal visits to a health care provider after perceiving decreased fetal movements are frequently observed in stillbirths. Informing pregnant women of the normal range of fetal movement frequency is essential in their earlier visits in order to prevent stillbirth.

Aim

To investigate the fetal movement frequency in late pregnancy and the effects of associated perinatal factors.

Methods

This prospective multicenter study was conducted in 20 obstetric facilities in our region of Japan. A total of 2337 pregnant women were asked to record the time it took to perceive 10 fetal movements by the modified ‘count to 10’ method every day from 34 weeks of gestation until delivery.

Findings

The 90th percentile of the time for the maternal perception of 10 fetal movements was 18–29 min, with a gradually increasing trend toward the end of pregnancy. The numbers of both pregnant women giving birth after 39 weeks’ gestation and infants with a birth weight exceeding 3000 g were significantly higher in mothers who took ≥30 min to count 10 fetal movements than in those who took <30 min.

Conclusion

The maternal perception time of fetal movements shows a gradually increasing trend within 30 min for 10 fetal movements by the modified ‘count to 10’ method. Informing pregnant women of the normal range of the fetal movement count time will help improve the maternal recognition of decreased fetal movements, which might prevent fetal death in late pregnancy.  相似文献
