Housing quality and access to material and learning resources within the home environment in developing countries     

Bradley RH  Putnick DL 《Child development》2012,83(1):76-91

This study examined home environment conditions (housing quality, material resources, formal and informal learning materials) and their relations with the Human Development Index (HDI) in 28 developing countries. Home environment conditions in these countries varied widely. The quality of housing and availability of material resources at home were consistently tied to HDI; the availability of formal and informal learning materials a little less so. Gross domestic product (GDP) tended to show a stronger independent relation with housing quality and material resources than life expectancy and education. Formal learning resources were independently related to the GDP and education indices, and informal learning resources were not independently related to any constituent indices of the overall HDI.  相似文献   

Chiming in on Museums and Participatory Culture     

Robert Stein 《Curator: The Museum Journal》2012,55(2):215-226

Abstract The deep trove of information available on the Internet and the expanding connections it affords to new communities online have been a transforming force in museums in the recent past. A single individual can publish thoughts and ideas to an audience of millions with a few simple clicks of a button. The cultural sector has made great strides in adopting these same methods to advance the missions and content of our organizations; however, a rise in participatory culture poses a number of challenges for the role of museums and our place in the evolving culture of our community. A debate surrounding the changing nature of authority and the participatory expectations of society is central to defining how museums can meaningfully engage with contemporary audiences. When making decisions that define how audiences play a role or not in their organizations, museums must consider the far‐reaching consequences of these choices on the relationships they have with their communities.  相似文献   

Looking Through Different Lenses: How Preservice Science Teachers Use Practice-Oriented Reflections to Negotiate More Reform-Minded Identities     

Robert M. Danielowich 《Journal of Science Teacher Education》2012,23(4):323-346

This study used identity as a framework to understand how preservice science teachers develop the reform-minded ideas inherent in science-specific reforms. Six participants systematically reflected about their reform-based and field lessons taught during a methods course and field lessons taught during student teaching. Patterns in their reflections revealed five different lenses they used to propose changing their practices and negotiate the dissonances those proposals created with their core conceptions about teaching. The extent to which participants expressed reform-minded thinking and enacted science-specific reforms in the field was associated with how they used the lenses to resolve dissonances. The findings suggest why preservice teachers need explicit opportunities to engage in work to cultivate the reform-minded identities required to enact science-specific reforms.  相似文献

“Life Between Fingers”: A Response to News Photography of an “Urban Ghetto”     

Robert E. Gutsche Jr. 《Visual Communication Quarterly》2014,21(1):14-23

This photo essay updates research previously presented in Visual Communication Quarterly about news characterizations of a “Black neighborhood” in Iowa City, Iowa. Shot by preschoolers in the city's Southeast Side, the images in this essay—peppered with the inadvertent appearance of the photographers' fingers—added to an artistic value that cast life there being other than dangerous, dark, and devious. Whereas hands can often be used to conceal, the fingers in these photographs frame special and specific glimpses of life, ultimately presenting a counternarrative to neighborhood characterizations constructed by news photographs.  相似文献   

Word Reading Fluency: Role of Genome‐Wide Single‐Nucleotide Polymorphisms in Developmental Stability and Correlations With Print Exposure     

Nicole Harlaar  Maciej Trzaskowski  Philip S. Dale  Robert Plomin 《Child development》2014,85(3):1190-1205

The genetic effects on individual differences in reading development were examined using genome‐wide complex trait analysis (GCTA) in a twin sample. In unrelated individuals (one twin per pair, n = 2,942), the GCTA‐based heritability of reading fluency was ~20%–29% at ages 7 and 12. GCTA bivariate results showed that the phenotypic stability of reading fluency from 7 to 12 years (r = 0.69) is largely driven by genetic stability (genetic r = 0.69). Genetic effects on print exposure at age 12 were moderate (~26%) and correlated with those influencing reading fluency at 12 (genetic r = 0.89), indicative of a gene–environment correlation. These findings were largely consistent with quantitative genetic twin analyses that used both twins in each pair (n = 1,066–1,409).  相似文献   

Strain,depressed mood and suicidal thoughts among maltreated adolescents in the United States     

Carol Coohey  April Dirks-Bihun  Lynette M. Renner  Robert Baller 《Child abuse & neglect》2014

Almost one-fourth of maltreated adolescents report they have thought about killing themselves in the last two weeks. We draw on Agnew's strain theory to develop a model to account for variability in suicidal thoughts among this high-risk group. We used data from a nationally representative sample of 572 maltreated adolescents, aged 11–15. One dimension of relational strain (poorer relationship with peers) and greater depressed mood were directly related to whether adolescents did or did not think about suicide. Depressed mood mediated the relationship between two strain variables (relationship with caregiver and with school) and suicidal thoughts. Child maltreatment strain (being severely harmed) and substance use were not directly related to suicidal thoughts; however, depressed mood appeared to mediate the relationship between drug use and suicidal thoughts. Adolescents who experience child maltreatment and who appear to be disconnected from caregivers, friends and school should be screened for depression and suicidal thoughts.  相似文献   

A contribution to the history of assessment: how a conversation simulator redeems Socratic method     

Robert Nelson  Phillip Dawson 《Assessment & Evaluation in Higher Education》2014,39(2):195-204

Assessment in education is a recent phenomenon. Although there were counterparts in former epochs, the term assessment only began to be spoken about in education after the Second World War; and, since that time, views, strategies and concerns over assessment have proliferated according to an uncomfortable dynamic. We fear that, increasingly, education is assessment-led rather than learning-led and ‘counter to what is desired’ in an ugly judgemental spirit whose moral underpinnings deserve scrutiny. In this article, we seek to historicise assessment and the anxieties of credentialising students. Through this longer history, we present a philosophy of assessment which underlies the development of a new method in assessment-as-learning. We hope that our development of a conversation simulator helps restore the innocence of education as learning-led, while still delivering on the incumbencies of assessment.  相似文献   

Impact of childhood maltreatment on physical health-related quality of life in U.S. active duty military personnel and combat veterans     

Laura H. Aversa  Jennifer Lemmer  Sarah Nunnink  Robert N. McLay  Dewleen G. Baker 《Child abuse & neglect》2014

Previous studies have found an association between childhood maltreatment (CM) and health-related quality of life (HRQoL), and to a lesser extent have considered whether psychiatric symptoms may explain the relationship. This study aimed to further our understanding of the link between CM and HRQoL by testing whether posttraumatic stress disorder (PTSD) or depressive symptoms mediate the relationship between childhood maltreatment and physical HRQoL. Mediation models were examined in a sample of male Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) active duty and combat veterans (n = 249). PTSD and depressive symptoms mediated the relationship between CM and overall physical HRQoL, as well as participation in daily activities due to physical health, bodily pain, and social functioning. Mediation of the relationship between childhood maltreatment and physical and social functioning by depression and PTSD symptoms may lend support to neurobiological hypotheses that childhood maltreatment sensitizes the nervous system and after repeated trauma may lead to the development of psychiatric symptoms, which have a major impact on morbidity and mortality.  相似文献
