Lack of access to potable water and good sanitation is still one of the most challenging public health concerns of the twenty-first century despite steady progress over recent decades. Almost a billion people globally lack access to safe water; over two billion live without adequate sanitation facilities. The challenge is even more daunting for Sub-Saharan Africa where coverage levels for both potable water and sanitation remain critically low. The urgent need to address the issue calls for adequate understanding of the socio-economic dimensions. Using the 2008 Ghana Demographic and Health Survey, we investigated the socio-economic and demographic factors associated with access to potable water and improved sanitation facilities. Our generalized linear models reveal that income, education, household size, and region are significant predictors of improved water and sanitation access. Our discussion and conclusion sections highlight the implications of the study results for water policy formulation and implementation in Ghana, and broadly for other developing countries.  相似文献

Time series data are increasingly common in many areas of the health sciences, and in some instances, may have natural boundaries serving as performance guidelines or as thresholds associated with adverse outcomes. Such boundaries may be labeled as semi-reflective, in that the time series values have an increased chance of returning towards middle levels as the boundaries are approached, but boundaries can still be breached. In this paper we review a model that was previously proposed for such data and we investigate its statistical properties. Specifically, this model consists of a third-order auto-regressive projection component, parameterized as a constrained linear combination of linear, flat, and quadratic trends, and an error term that uses a logistic regression model for its sign. We describe and compare a previously-proposed estimation method with a modified version thereof, using computer simulations, as well as data examples from heart monitoring and from a driving simulator. We find that the two methods tend to give different results, with the modified technique having lower bias and more accurate confidence intervals than the previously-proposed method.  相似文献

This study investigated differences in depressive symptoms, loneliness, and self-esteem for monosexual (lesbian, gay) and plurisexual (bisexual, pansexual, queer) sexual minority youth (SMY) by relationship status (single, partnered) and relationship configuration (same-gender partner, different-gender partner). Participants included 338 SMY (Mage = 19.10 years) who reported on their relationship status, partner's gender identity, well-being, and ability to confide in partner about LGBTQ issues. Results indicated that for plurisexual youth, single status was associated with greater loneliness; plurisexual youth with same-gender partners reported fewer depressive symptoms and marginally greater ability to confide in their partner about LGBTQ issues than those with different-gender partners. Findings reveal similarities across SMY while also highlighting some unique challenges among plurisexual youth with different-gender partners.  相似文献

This article summarizes the four articles in the Social Development quartet focused on positive affect regulation in youth. Each article in the quartet shows that parents’ socialization of youth positive affect (e.g., encouraging, enhancing, savoring, or dampening responses) is associated with youth positive affect regulation and depressive symptoms. Further, three of the studies provide novel evidence for an indirect relationship whereby parental socialization predicts youth depressive symptoms through youth positive affect regulation. The studies include samples of youth across mid‐childhood and adolescence (7–18‐year‐olds) from three countries (the United States, Belgium, and India), and utilize several methods of assessing youth positive affect regulation or parental socialization (parent‐reported surveys, youth‐reported surveys, coded parent–child discussions). This integrative article also identifies several ways in which the study of youth positive affect regulation can be advanced. We address the conceptualization of positive affect regulation and the socialization of children's positive affect, constraints on the adaptiveness of upregulating positive emotions, methodological directions, potential moderated effects based on child characteristics such as sex or temperament, and the importance of studying outcomes beyond depression.  相似文献

This article analyzes the arguments of two of the central positions in the debate over assimilationism in the gay and lesbian community as a means of exploring the meaning of resistance, opposition, struggle, and agency within the context of a dominant and generative field of power. Instead of debating which position is better or most effective, or which involves true resistance, we use Foucault's formulations to suggest that each represents but one among a multiplicity of strategies, all existing simultaneously in a field of power. Because this field is composed of a plurality of dissonant, multi-layered, multidimensional relations of power, we argue that no single form of resistance can be identified and uniquely practiced. Instead, each struggle contributes its own partial modification to the overall transformation of the field of power, and simultaneously highlights the inconsistencies faced by agents who attempt to present a coherent identity in opposition to structures of domination.  相似文献

Cross-sectional studies support negative associations between children’s skills in recognizing emotional expressions and their problem behaviors. Few studies have examined these associations over time, however, precluding our understanding of the direction of effects. Emotion recognition difficulties may contribute to the development of problem behaviors; additionally, problem behaviors may constrain the development of emotion recognition skill. The present study tested the bidirectional linkages between children’s emotion recognition and teacher-reported problem behaviors in 1st and 3rd grade. Specifically, emotion recognition, hyperactivity, internalizing behaviors, and externalizing behaviors were assessed in 117 children in 1st grade and in 3rd grade. Results from fully cross-lagged path models revealed divergent developmental patterns: Controlling for concurrent levels of problem behaviors and first-grade receptive language skills, lower emotion recognition in 1st grade significantly predicted greater internalizing behaviors, but not hyperactivity or externalizing behaviors, in 3rd grade. Moreover, greater hyperactivity in 1st grade marginally predicted lower emotion recognition in 3rd grade, but internalizing and externalizing behaviors were not predictive of emotion recognition over time. Together, these findings extend previous research to identify specific developmental pathways, whereby emotion recognition difficulties contribute to the development of internalizing behaviors, and early hyperactivity may contribute to the development of emotion recognition difficulties, thus highlighting the importance of examining these processes and their mutual development over time.  相似文献

This study examined the interaction effects of the amount of practice and the cane technique used in drop-off detection with a sample of 32 adults who were blind. The advantage of the constant contact technique over the two-point touch technique was significantly greater for the less experienced cane users than for the more experienced ones.  相似文献
