The debate over how to best guide HIV-infected mothers in resource-poor settings on infant feeding is more than two decades
old. Globally, breastfeeding is responsible for approximately 300,000 HIV infections per year, while at the same time, UNICEF
estimates that not breastfeeding (formula feeding with contaminated water) is responsible for 1.5 million child deaths per
year. The largest burden of these infections and deaths occur in Sub-Saharan Africa. Using this region as an example of the
burden faced more generally in other resource-poor settings, we contrast the evolution of the clinical standard of care for
infant feeding with HIV-infected mothers in high-income countries to the current international clinical guidelines for HIV-infected
mothers and infant feeding in resource-poor settings. While the international guidelines of exclusive breastfeeding for a
6-month period seem to offer the least-worst strategy for reducing mother-to-child transmission of HIV during infancy while
conferring some immunity through breastfeeding post-6 months, we argue that the impact of the policy on mothers and healthcare
workers on the ground is not well understood. The harm reduction approach on the level of health policy translates into a
complicated, painful moral dilemma for HIV-positive mothers and those offering them guidance on infant feeding. We argue that
the underlying socio-economic disparities that continue to fuel the need for a harm reduction policy on infant feeding and
the harm to women and children justify: (1) that higher priority be given to solving the infant feeding dilemma with improved
data on safe feeding alternatives, and (2) support of innovative, community-driven solutions that address the particular economic
and cultural challenges that continue to result in HIV-transmission to children within these communities.

The present study evaluated the hypothesis that measures of linguistic skills differentially contribute to the variability in reading achievement at different ages. Linguistic skills that develop earlier and are more important for earlier phases of reading were predicted to contribute more to the variability of reading achievement at earlier ages (5–7) than at older ages (10–12). Conversely, linguistic skills that develop later and are more important for later phases of reading were predicted to contribute more to the variability in reading achievement at older ages (10–12) than at younger ages (5–7). To test these developmental hypotheses, measures of language skills with different developmental rates were administered to cross-sectional samples of disabled and nondisabled readers at three mean ages: 5.5, 8.5, and 11 years. Reading group differences were apparent at each age on measures assumed to develop earlier, thus failing to confirm the first prediction. However, these measures may not have been sensitive to linguistic skills important for beginning reading. Reading group differences on measures of later developing language skills were apparent only for older readers, thus confirming the second prediction. The latter age-dependent relationships provided additional evidence for developmental changes in the linguistic correlates of reading achievement. 相似文献

As visual technologies become increasingly networked online, websites like YouTube provide a space to share vlogs (video blogs) online, suggest related content for viewers, and help in/form virtual communities, including those of mental illness. Within this space, vlogs of schizophrenia and comments generated about them by other users can represent transitional, dialogical states of illness that speak back to the analog body and affect a body’s way of being in the world. Moreover, as vlogs create resistance against static definitions of schizophrenia, they may foster a creativity, experimentation, and inventiveness that transforms understandings of schizophrenia within the sciences and humanities. 相似文献

Generalization of Sight Word Accuracy using a Common Stimulus Procedure: A Preliminary Investigation
Eric M. Mesmer Gary J. Duhon Karen Hogan Brandi Newry Savannah Hommema Courtney Fletcher Maggie Boso 《Journal of Behavioral Education》2010,19(1):47-61
The need to investigate strategies promoting the generalization of reading skills is well documented. The current study builds
upon previous literature by examining the impact of a common stimulus procedure on accuracy of reading generalization words
in isolation. The common stimulus procedure used in this study intended to enhance the salience of the orthographic and phonemic
features between taught and generalization words by highlighting the common rime structure in each word with a specific color.
Taught and generalization words representing four word families were used (e.g., end, et, ell, & en). Using a multiple-baseline
design across three participants with a replication of procedures for a fourth student, the impact of the common stimulus
on accuracy of reading generalization words was examined. Results demonstrated increased accuracy and stability of responding
when common stimulus procedures were implemented. 相似文献

Prior research and theory suggest that people use three main sets of criteria in mate selection: warmth/trustworthiness, attractiveness/vitality, and status/resources. In two studies, men and women made mating choices between pairs of hypothetical potential partners and were forced to make trade-offs among these three criteria (e.g., warm and homely vs. cold and attractive). As predicted, women (relative to men) placed greater importance on warmth/trustworthiness and status/resources in a potential mate but less importance on attractiveness/vitality. In addition, as expected (a) ratings of ideal standards partly mediated the link between sex and mate choices, (b) ideal standards declined in importance from long-term to short-term relationships, with the exception of attractiveness/vitality, and unexpectedly, (c) sex differences were higher for long-term (compared to short-term) mate choice. Explanations and implications are discussed. 相似文献
