ABSTRACTThis study examined conflict, parenting communication style, and attitudes regarding the parent-child relationship for a marginalized special population: incarcerated mothers and their children. Bronfenbrenner’s bio-ecological perspective served as a guiding framework, based on its ability to consider family interactions across ecological contexts, both proximal and distal to the developing child’s home setting. Fifty incarcerated mothers in the central U.S. provided in-depth interviews and individual self-report surveys. Findings indicate that incarcerated mothers most frequently used an authoritative parenting communication style in conflict situations that ended positively, and authoritarian style in conflict that ended negatively. Authoritative parenting was associated with incarcerated mothers’ reports of greater satisfaction with parenting. Study findings suggest that parenting communication style can help support efforts to reduce recidivism. Contextualizing these findings within Bronfenbrenner’s model, the present study affirms the role of proximal as well as distal factors governing relational communication between incarcerated mothers and their children. 相似文献

Psychosocial discomfort may amplify job-related risk factors. The aim of this study is to evaluate job stress in a high fashion clothing company with upper limb biomechanical overload due to repetitive and forceful manual activities. Biomechanical risk was analyzed and in part reduced using the OCRA Check list. A total of 518 workers (433 females and 85 males) were investigated to determine anxiety (by STAI 1 and 2), occupational stress (using the Italian version of the Karasek Job Content Questionnaire) and perception of symptoms. Final biomechanical assessment did not reveal high risk jobs, except for cutting. Although the perception of anxiety and job insecurity was within the normal range, all the workers showed a high level of job strain (correlated with the perception of symptoms) due, probably, to very low decision latitude. It was suggested that job strain may increase the perception of symptoms. Moreover, the result of this study indicates that musculoskeletal overload has to be further analyzed since its low level is not in agreement with the level of discomfort due to the repetitive tasks. 相似文献

A statistical method is presented to determine the optima design of air quality networks detecting warning and alert levels.
A simulation model is used to describe temporal and spatial variations of atmospheric pollutants; air quality patterns serve
as the database of the procedure to design the network. Only the sites exceeding warning and alert levels, at different meteorological
scenarios, are considered as potential monitoring stations. For the selection of the optima set, spatial and temporal representativity
criteria are introduced; accordingly, the optima set provides a complete representativity of the space and time considered.
The method is applied to the Mestre urban area, in Venice district, for the carbon monoxide pollutant. 相似文献

We present an equilibrium model of the market for higher education. Our model simultaneously predicts student selection into institutions of higher education, financial aid, educational expenditures, and educational outcomes. We show that the model gives rise to a strict hierarchy of colleges that differ by the educational quality provided to the students. We also develop a new estimation procedure that exploits the observed variation in prices within colleges. Identification is based on variation in endowments and technology. It does not rely on observed variation in potentially endogenous characteristics of colleges such as peer quality measures and expenditures. We estimate the structural parameters using data collected by the National Center for Education Statistics and aggregate data from Peterson's and the National Science Foundation. 相似文献

This article investigates the heterogeneous effects of international migration on the expenditure of Bangladeshi migrant households. Adopting a counterfactual framework, we estimate the impact of migration on per capita expenditure of left‐behind households according to their position in the counterfactual expenditure distribution and the length of the migration period. The effects on households’ social mobility and on inequality are also assessed. The analysis indicates that migration has a positive impact on per capita expenditure and represents an important vehicle of social mobility, but may also be a source of inequality. We also find that only a tiny share of international migrants originates from households belonging to the lowest expenditure quintile and, since most of the characteristics which seem to influence the migration decision cannot be shaped by policy interventions, our results also suggest that pro‐migration policies might not be effective in lifting those most in need out of poverty. 相似文献

This qualitative study explored parents’ perspectives on the collateral consequences of youth sexual offending on siblings through the analysis of interview data among 16 caregivers from 10 Canadian families. Using thematic coding procedures, findings indicated that parents identified a range of safety, emotional and interpersonal impacts on siblings beginning with the criminal justice and child welfare investigations of the sexual offending and extending to siblings’ relationships with the offending youth, their caregivers and other relatives. Results demonstrate the need for greater acknowledgement of, and parent‐informed interventions that specifically address the impact of youth sexual offending on siblings by professionals and non‐professionals (e.g. relatives) alike. 相似文献

A growing body of evidence suggests a role for homocysteine (Hcys) and folate (FA) in erectile function (EF): Hcys appears to impair EF affecting endothelium via several mechanism whereas the role of FA remains to be elucidated, besides decreasing Hcys. To assess correlation between erectile dysfunction (ED) and serum levels of FA, Hcys, and B12, we enrolled 31 patients affected by ED (Group A; age 52.83?±?11.89 years) and 31 healthy adults (Group B; age 49.14?±?13.63 years). Fasting blood samples were taken for each subject. ED was assessed by the International Index of Erectile Function-5 (IIEF-5). IIEF-5 mean score was significantly lower in Group A than in Group B (10.71?±?4.24 versus 23.32?±?1.33, p?.001). Compared to Group B, Group A also showed significantly lower serum FA levels (5.11?±?1.79 versus 7.9?±?3.55?ng/ml, p?.001) and significantly higher serum Hcys levels (13.61?±?3.55 versus 9.17?±?2.32 µmol/L, p?.001). No significant correlation was observed between Hcys and FA both groups. Our results showed a significant association among ED, FA deficiency and hyperomocisteinemia. Lack of correlation between FA and Hcys suggests that FA deficit may directly impair EF. 相似文献

A Systematic Literature Review on Recent Lean Research: State‐of‐the‐art and Future Directions 下载免费PDF全文
Lean management (LM) has attracted the interest of scientists and practitioners since 1990, when Womack et al. (Womack, J.P., Jones, D.T. and Roos, D. (1990). The Machine that Changed the World. New York, NY: Rawson Associates) popularized the Japanese manufacturing approach aimed at eliminating waste to improve operational performance and customer satisfaction. Over the years, the lean concept has evolved becoming a managerial paradigm applicable to different sectors and processes with impressive results. This heterogeneity of implementations and settings makes the recent LM literature diverse and fragmented, and an extensive analysis of the latest contributions on this field is lacking. To address this gap, the authors propose a systematic literature review (SLR) of 240 articles published in 25 peer‐reviewed academic journals from January 2003 to December 2015. The purpose is to analyse the recent trends in this area and to provide a framework that organizes lean researched issues into mature, intermediate and nascent, based on their position in the research life cycle. Starting from the gaps that the SLR highlights, the authors suggest conducting lean research in the following directions: (a) grounding lean studies on existing managerial theories; (b) addressing service settings such as banking/finance, public sector and education; (c) exploring the role of national culture through cross‐country comparisons; (d) defining and conceptualizing ‘lean‐x’ processes; (e) understanding the relationships between lean and safety/environmental issues, and (f) unveiling the effects on social outcomes. Finally, the proposed framework helps scholars find issues not sufficiently explored that require theory‐building research (to move from nascent to intermediate) or theory‐testing research (to move from intermediate to mature). 相似文献
