We test three hypotheses about the role of housing affordability in child cognitive achievement, behavior, and health. Using longitudinal data from the Panel Study of Income Dynamics, we apply both propensity-score matching and instrumental-variable modeling as identification strategies and test the sensitivity of results to omitted variable bias. The analysis reveals an inverted-U-shaped relation between the fraction of income devoted to housing and cognitive achievement. The inflection point at approximately 30% supports the long-standing rule-of-thumb definition of affordable housing. There is no evidence of affordability effects on behavior or health. 相似文献

Despite technological advances, human remains detection (HRD) dogs still remain one of the best tools for locating clandestine graves. However, soil texture may affect the escape of decomposition gases and therefore the effectiveness of HDR dogs. Six nationally credentialed HRD dogs (three HRD only and three cross‐trained) were evaluated on novel buried human remains in contrasting soils, a clayey and a sandy soil. Search time and accuracy were compared for the clayey soil and sandy soil to assess odor location difficulty. Sandy soil (p < 0.001) yielded significantly faster trained response times, but no significant differences were found in performance accuracy between soil textures or training method. Results indicate soil texture may be significant factor in odor detection difficulty. Prior knowledge of soil texture and moisture may be useful for search management and planning. Appropriate adjustments to search segment sizes, sweep widths and search time allotment depending on soil texture may optimize successful detection. 相似文献

Personal narratives tell the stories of people’s lives as well as provide insight into the meaning of those experiences. These narratives both reflect and are influenced by the relationships within which an individual is embedded. In this study, autobiographical narratives for two groups of women were compared: women who had experienced habitual gender-based domestic violence in their couple relationships and women who had not. The language of narratives was analyzed by LIWC (Language Inquiry and Word Count procedure). Results showed that the language and structure of narratives by women with a history of domestic violence indicated greater stress and trauma, more incoherent space-time organization, and poorer relationship quality. Women who experienced violence wrote longer narratives that contained proportionately more negative emotion words and more references to cognitions and physical/body issues, and indicated more disorganized structure by means of incoherent use of verbal tense, more impoverished use of connectives, and greater use of negative sentence syntax and discrepancy words. They also included proportionately more pronoun references to ‘I’,‘You’,’ and ‘He’, indicating self vs. partner conflictual relationships. However, women who had experienced relationship violence for longer decreased their references to the emotions of fear and anxiety, suggesting adaptation to violence over time. 相似文献

There is a lack of consensus on whether the use of intimate partner violence (IPV) is distinctly different between men and women, or if men and women share similar risk markers for perpetrating IPV. In this study, we compared 60 different risk markers for IPV perpetration for men and women using a meta-analysis. We found three out of 60 risk markers significantly differed between men and women. Our results suggest that there are more similarities between men and women than there are differences in risk markers for IPV perpetration. 相似文献

Cottee (Br J Criminol 54(6):981–1001, 2014) makes the case that criminology has much to contribute to an understanding of theistic violence. However the ‘hubris of positivism’ (Young in The criminological imagination, Polity, Cambridge, 2011) curtails the criminological imagination and this is particularly evident in the debates that permeate contemporary understandings of religious extremism and radicalisation. Using the terrorist attacks in France 2015 as a touchstone, this paper explores the current state of criminological engagement with these issues. First a synopsis of orthodox current criminological talk about religious extremism and violent crime is considered. Next a critical analysis of the events in Paris based around what is ‘known’ about them is offered in the light of this knowledge. Finally, drawing on the work of Young (2011) the implications of this analysis for criminology are considered resulting in a refinement of the biases identified by Cottee (2014). 相似文献
