County child poverty rates in the US: a spatial regression approach   总被引:2,自引:0,他引:2  
We apply methods of exploratory spatial data analysis (ESDA) and spatial regression analysis to examine intercounty variation in child poverty rates in the US. Such spatial analyses are important because regression models that exclude explicit specification of spatial effects, when they exist, can lead to inaccurate inferences about predictor variables. Using county-level data for 1990, we re-examine earlier published results [Friedman and Lichter (Popul Res Policy Rev 17:91–109, 1998)]. We find that formal tests for spatial autocorrelation among county child poverty rates confirm and quantify what is obvious from simple maps of such rates: the risk of a child living in poverty is not (spatially) a randomly distributed risk at the county level. Explicit acknowledgment of spatial effects in an explanatory regression model improves considerably the earlier published regression results, which did not take account of spatial autocorrelation. These improvements include: (1) the shifting of “wrong sign” parameters in the direction originally hypothesized by the authors, (2) a reduction of residual squared error, and (3) the elimination of any substantive residual spatial autocorrelation. While not without its own problems and some remaining ambiguities, this reanalysis is a convincing demonstration of the need for demographers and other social scientists to examine spatial autocorrelation in their data and to explicitly correct for spatial externalities, if indicated, when performing multiple regression analyses on variables that are spatially referenced. Substantively, the analysis improves the estimates of the joint effects of place-influences and family-influences on child poverty.

This article presents a qualitative arts-informed inquiry on teaching and learning in social work education. Using arts-informed research methodology and grounded theory methodology, the research analyses ten interviews of social work educators in two Canadian provinces. This article focused on how university educators use arts-informed methods of teaching about social justice through anti-racist and decolonizing lenses; also discussed are the educators’ personal and professional transformation and development within this process. The main findings discuss the importance of creating an ‘artful’ space as a platform for experiential, embodied and emotive learning, which offers an innovative, more holistic and comprehensive way of teaching social justice. This way of teaching emphasizes personal transformation, giving space to marginalized voices and expression; as well as collective co-creation of meaning and creating practical tools for future social change. The study also touches upon challenges and gaps in using an arts-informed approach, which include student resistance to alternative ways of education, expressed specifically by racialized educators and ambiguity related to assessing artful works in an academic setting. The paper ends with recommendations for social work education.  相似文献

Social casino games are online gambling-like games found on social networking sites. They are initially free to play, however, players are encouraged to make micro-transactions (i.e., in-game purchases) for additional game credits or functionality. As a result, they generate billions of dollars in revenue. Yet, little is known as to who purchases virtual credits, let alone why. In the present research, we assessed whether there are individual differences (impulsivity, reward sensitivity, competitiveness, and problem gambling severity) between who is and who is not likely to make micro-transactions during social casino game play. Moreover, we examined possible motivations for making micro-transactions (e.g., extend play, win back lost credits) and whether the individual difference variables of interest predict reported motivation(s) for making micro-transactions. Results showed that social casino gamers who engaged in micro-transactions reported significantly higher levels of impulsivity, reward sensitivity and problem gambling severity, but not competitiveness. In terms of motivation to make micro-transactions, desire to extend play was endorsed most frequently, followed by a desire to access additional features, chasing lost credits, and to speed up play. Lastly, among participants who made micro-transactions, reward sensitivity predicted making micro-transactions to chase lost credits. These results suggest the personality make-up of social casino gamers is important to understand who is likely to make micro-transactions as well as their motivation to do so—information that could prove useful for regulation of the industry.  相似文献

Problem

Low prenatal well-being has adverse outcomes for mother and infant but few interventions currently exist to promote and maintain prenatal well-being.

Background

Mindfulness and gratitude based interventions consistently demonstrate benefits in diverse populations. Interventions integrating these constructs have potential to improve psychological and physiological health during pregnancy.

Aim

The aim of this pilot study is to examine the effect of a novel gratitude and mindfulness based intervention on prenatal stress, cortisol levels, and well-being.

Methods

A pilot randomised controlled trial was conducted with 46 pregnant women. Participants used an online mindfulness and gratitude intervention 4 times a week for 3 weeks. Measures of prenatal stress, salivary cortisol, gratitude, mindfulness, and satisfaction with life were completed at baseline, 1.5 weeks later, and 3 weeks later.

Findings

Intervention participants demonstrated significant reductions in prenatal stress in comparison to the control condition (p = .04). Within subjects reductions in waking (p = .004) and evening cortisol (p > .001) measures were observed for intervention participants. Significant effects were not observed for other well-being outcomes.

Discussion

Reducing self-report and physiological stress in pregnancy can improve maternal and infant outcomes. The findings of this pilot study indicate potential direct effects of the intervention on self-reported stress in comparison to a treatment-as-usual control. Effects on a biomarker of stress, cortisol, were also observed within the intervention group.

Conclusion

A brief mindfulness and gratitude based intervention has the potential to reduce stress in pregnancy. Future research is needed to further explore mechanisms and potential benefits of such interventions.  相似文献

Sociologists have long recognized that social problems do not derive solely from objective conditions but from a process of collective definition. At the core of some social issues are framing competitions, struggles over the production of ideas and meanings. This article examines competing cultural meanings about the fat body. Through frame analysis of organizational materials, I map the contested field of obesity and document three cultural frames—medical frame, social justice frame, and market choice frame—as represented by the Centers for Disease Control and Prevention (CDC), the National Association to Advance Fat Acceptance (NAAFA), and the food industry group the Center for Consumer Freedom (CCF), respectively. Using the “framing matrix,” I explore each frame's key signature elements and discuss its social and cultural significance. Notably, each frame leads to different outcomes for social equality and how society thinks about fat bodies, health, and public policy.  相似文献

There is a considerable number of researches about workplace violence, but few relate young workers and work harassment. This study aimed to investigate the reported perceptions of young apprentices and trainees about moral harassment at work and related coping strategies. Forty adolescent workers (22 men and 18 women) between 15 and 20 years old who received training by a non-governmental organization in S?o Paulo, Brazil, participated in the study. Data collection included individual and collective interviews. It was used an in-depth semi structured interview protocol. The discourses were analyzed using the hermeneutic-dialectic frame. Results showed that young workers reported little or no knowledge of strategies to cope with moral harassment at work, showing vulnerability to the effects of aggression. Effective coping strategies at work should embrace two important concepts of health promotion: empowerment and autonomy.  相似文献

This pilot study examined the feasibility and potential efficacy of a self-management program for seniors with chronic back pain and assessed for possible race/ethnicity differences in program impact. Sixty-nine seniors (24 African Americans, 25 Hispanics, and 20 non-Hispanic Whites) enrolled in the 8-wk community-based program. Efficacy outcomes included pain-related disability as measured by the Roland Morris Disability Questionnaire (RMDQ), pain intensity, pain self-efficacy, depressive symptoms, social activity, and functional status. Eighty percent of enrollees completed the program. Clinically important decreases in RMDQ scores were found for non-Hispanic White (adjusted change score = -3.53), African American (-3.89), and Hispanic (-8.45) participants. Improvements in all other outcomes were observed, but only for Hispanic participants. Results confirm that implementation of the protocol in urban senior centers is feasible, and the program shows potential efficacy. The race/ethnicity differences observed in the current study merit further investigation.  相似文献

Upon encountering victim resistance during the commission of a sexual assault, an offender makes a decision as to how to react to the resistance via the use of varying degrees of coercive or noncoercive tactics. Exhaustive chi-squared automatic interaction detection (CHAID) analyses were performed on a sample of 369 criminal events to detect the significant situational and crime-specific factors, the pertinent interactions between these factors, and how these affect an offender's reaction to victim resistance depending on whether the victim is a child or an adult. Findings show that multiple interactions do occur and, moreover, factors affecting the offender's reaction to victim resistance are very different depending on whether the victim is a child or an adult. Planning and preparation variables, such as the offender's attack strategy, were found to be significant in the child victim model, whereas reactive variables, such as the type of victim resistance, were found to be significant in the adult victim model. The findings lend support to the social interac-tionist perspective and the importance of victim-offender dynamics.  相似文献

Some female victims of nonconsensual sex subsequently have consensual sexual intercourse with the perpetrator and are more likely to do so if intercourse occurred during the nonconsensual sex than if it did not. Some evolutionary psychologists have postulated that there is something significant about nonconsensual intercourse that causes women to subsequently have a sexual relationship with the perpetrator (e.g., risk of pregnancy). In this study, we investigated a parsimonious explanation that has previously been overlooked: Intercourse is more likely during nonconsensual sex when the victim and perpetrator have previously had a sexual relationship; thus, subsequent consensual intercourse may simply be a continuation of that prior relationship. A sample of 945 women completed an Internet-based survey, of whom 41% had experienced nonconsensual sex since age 14. As expected, victims who had intercourse with perpetrators prior to the nonconsensual sex event were significantly more likely than other victims to experience nonconsensual intercourse and to engage in subsequent consensual intercourse with the perpetrator. When considering only the small subsample of victims who never had a prior romantic or sexual relationship with the perpetrator, the odds of subsequent consensual intercourse were still significantly greater following nonconsensual sex with intercourse versus without intercourse.  相似文献
