In many developing regions, women and young girls spend several hours daily in the collection of natural resources. Still the link between these household resource strategies and stakeholder perceptions of development priorities remains unexplored. This project examines this association with survey data representative of the adult population from Ghana’s Coastal Region. Although natural resource scarcity and the sustainability of resource use represent key development challenges, there are others (e.g., energy, sanitation, employment, and educational opportunities). As such, even in the face of natural resource scarcity, individuals may place greater importance on other dimensions of development, especially if household resource strategies are perceived as relatively efficient. The analytical focus here is on water and the results suggest that gender roles shape household water collection strategies, while also shaping these strategies’ perceived opportunity costs. Specifically, Ghanian adults more often see drinking water provision as their primary development need when water sources are distant and/or when male household members collect water (particularly male heads). In the end, I argue that social science inquiry benefits by contextualizing social dynamics within environmental context, particularly within cultural settings in which human subsistence is intimately tied to the state of the natural environment.  相似文献

Poor children1     
This article explores trends in child poverty in the UK since 1979 and examines the extent to which the government is making progress in pursuit of its objective to abolish child poverty in 20 years. The spatial distribution of child poverty is examined by country, local authority and ward. The characteristics of households containing poor children are presented and research on the dynamics of child poverty reviewed. Child poverty in the UK trebled during the 1980s and has only just begun to fall slowly. Child poverty is heavily spatially concentrated and the risks of child poverty are concentrated in certain types of household. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

This study focuses on levels of concern for hurricanes among individuals living along the Gulf Coast during the quiescent two‐year period following the exceptionally destructive 2005 hurricane season. A small study of risk perception and optimistic bias was conducted immediately following Hurricanes Katrina and Rita. Two years later, a follow‐up was done in which respondents were recontacted. This provided an opportunity to examine changes, and potential causal ordering, in risk perception and optimistic bias. The analysis uses 201 panel respondents who were matched across the two mail surveys. Measures included hurricane risk perception, optimistic bias for hurricane evacuation, past hurricane experience, and a small set of demographic variables (age, sex, income, and education). Paired t‐tests were used to compare scores across time. Hurricane risk perception declined and optimistic bias increased. Cross‐lagged correlations were used to test the potential causal ordering between risk perception and optimistic bias, with a weak effect suggesting the former affects the latter. Additional cross‐lagged analysis using structural equation modeling was used to look more closely at the components of optimistic bias (risk to self vs. risk to others). A significant and stronger potentially causal effect from risk perception to optimistic bias was found. Analysis of the experience and demographic variables’ effects on risk perception and optimistic bias, and their change, provided mixed results. The lessening of risk perception and increase in optimistic bias over the period of quiescence suggest that risk communicators and emergency managers should direct attention toward reversing these trends to increase disaster preparedness.  相似文献

This article explores masculinities and changes in men’s lives in the rural oil fields of Chad during the period of an oil and pipeline project described by the World Bank as a “model” for oil-as-development. In many parts of Africa, private sector investment is concentrated in the extractive industries, especially oil and gas projects. Africa’s emerging oil economies entail new institutional configurations, or what Michael Watts called an “oil complex,” that challenge antecedent norms and forms of identity. In this article, I describe the expectations, desires, and experiences of three distinct groups of men—those who found temporary employment on the project, those who continued to make a living from farming while contending with land expropriation, and those who migrated to oil field towns in search of work—to make three general points about the oil complex and masculinities in Chad. The structure of the global oil industry meant that local men who found jobs on the project could act as breadwinners and patriarchs, but only temporarily; local workers struggled post-employment with their exclusion from the possibilities associated with the project. Men who never found jobs continued to eke out a living from the land, but state-of-the-art policies governing land expropriation led simultaneously to conflict in families and greater economic interdependence among family members. Finally, in the low-media environment of the oil field region, ideas and images about sex, sexuality, and love emanating from the transient and hyper-masculine global oil industry workforce served as models for landless young men who migrated to oil field towns and who, in the absence of work, sought to transform themselves into objects of desire through the mediation of pharmaceuticals.

Mindfulness-based interventions are effective at improving symptoms of sexual dysfunction in women. The mechanisms by which mindfulness improves sexual function are less clear. The main objective of our study was to investigate the impact of a mindfulness task on sexual response in women. Forty-one women (mean age = 27.2, SD = 5.6) participated in two laboratory sessions that each included two erotic films and one attention task that were presented in counterbalanced order. Both attention tasks consisted of a six-minute audio recording of either a modified body scan, focusing on genital arousal sensations (mindfulness condition), or a visualization exercise. Subjective and genital sexual arousal were measured continuously during stimulus presentation. The mindfulness task led to greater subjective and lower genital arousal. The agreement of subjective and genital sexual arousal (i.e., concordance) was greater in the mindfulness condition. Trait mindfulness was related to lower sexual arousal but also greater sexual concordance in women. Mindfulness-based interventions that encourage women to focus on physical arousal sensations in the here and now may be associated with women’s improved sexual function by enhancing feelings of sexual arousal during sexual activity and by increasing concordance between subjective and genital sexual arousal.  相似文献

The teaching of decision sciences presupposes that careful attention is directed toward improving students' critical thinking and analytical skills. This paper presents an approach to teaching quantitative methods classes that focuses on developing student skills in the areas of analytical and critical thinking through written and oral communication. The approach requires very little additional instructor preparation time and does not require the instructor to make major changes in either the content or organization of the course. While the instructor's investment is minimal, the benefits to the students appear to be substantial.  相似文献

This paper presents a data driven modeling (DDM) approach to certain types of optimization problems. DDM relinquishes control of the completed model to the user department rather than the operations research (OR) staff. The approach emphasizes development of models that are dependent on data maintained and understood by the users. The data base consists of coded user rules which describe when changes will occur in the problem structure and data which captures the generalization of the problem. Both the rules and data can be updated by user department personnel. These data drive a matrix generator controlled by the rules which uses the data base as input to generate the specific model formulation. This DDM system is designed by OR consultants or staff to allow independence of use along with low-cost and minimal-effort maintenance. The DDM approach is illustrated with an application to a real-world medical scheduling problem.  相似文献

Achievement of early motor milestones in infancy affords new opportunities for social interaction and communication. Research has shown that both motor and social deficits are observed in infants who later develop autism spectrum disorder (ASD). This study examined associations between motor and Social communication skills in 12‐month‐old infant siblings of children with ASD who are at heightened risk for developmental delays (N = 86) and low‐risk, typically developing infants (N = 113). Infants were classified into one of three groups based on their walking ability: walkers (walks independently), standers (stands independently), or prewalkers (does not yet stand or walk independently). Social communication and cognitive skills were assessed with two standardized assessments (Communication and Symbolic Behaviors Scales [CSBS] and Mullen Scales of Early Learning) and compared across the three walking groups. Results demonstrated that high‐risk walkers showed superior Social communication skills, but commensurate cognitive skills, compared to high‐risk prewalkers. In contrast, Social communication and cognitive skills were largely comparable for low‐risk infants, regardless of walking status. Findings suggest that for high‐risk infants, who are already vulnerable to developmental delays and ASD, independent walking may facilitate the emergence of Social communication abilities. Pivotal motor milestones may serve as useful indicators of Social communication delays and targets for intervention.  相似文献

Persons referred by Child Protective Services (CPS) for substance abuse evidence high rates of nonattendance to therapy sessions, taxing systems of care and exacerbating outcomes. This study examined the influence of two telephone-based incentive programs on therapy session attendance in mothers who were referred by CPS for substance abuse. After baseline therapy session attendance was established in an evidence-based clinic that incorporated a telephone engagement intervention (Phase I), participants were provided free cellular telephones with limited minutes and permitted to order free meals delivered by the therapist during upcoming sessions (Phase II). The third phase was similar to Phase II, but participants were provided unlimited minutes. Results indicated that participants’ attendance was significantly improved when meals and cellular telephone minutes were contingent on attendance. Although the percentage of sessions attended by participants during Phase III was higher than Phase II, unlimited minutes and meals did not significantly enhance attendance relative to limited minutes and meals. Session attendance for significant others of these participants was significantly higher during Phase III as compared with Phase I. Session attendance of significant others was statistically similar between Phase I and II and between Phase II and Phase III. Study implications and recommendations for future research and practice are discussed in light of the findings.  相似文献
