School characteristics associated with the educational resilience of low-income and ethnic minority youth

textThis study empirically tested Benard’s (1991, 2004) theory of resilience and youth development by examining the influence of caring relationships, high expectations and opportunities for participation and contribution within the schools on the mathematics achievement and timely graduation of public high school students. Additional analyses focused on subsamples of students who were at risk of academic failure and school dropout—students from the lowest socioeconomic quartile, African American and Hispanic students, and a generic at-risk sample that includes students from these three groups plus students who had nontraditional families, had a disability, or were retained a grade in school. The study used data from the Educational Longitudinal Study: 2002, which was designed to monitor young people as they transition from tenth grade to postsecondary education and/or employment. Hierarchical Linear Models and Hierarchical Generalized Linear Models were used for the analyses. Experiences within the schools that conveyed caring relationships, high expectations, and opportunities for participation and contribution were associated with higher senior year mathematics achievement scores and increased odds of timely graduation for the overall public school sample and for the at-risk groups. Suggestions are made for increasing caring relationships, high expectations, and opportunities for participation and contribution within the schools. The limitations of this study and directions for further research are also discussed.Social Wor

Your Second Home: Re-thinking of Post-disaster Housing

Natural disasters such as tornadoes, wildfires, earthquakes, and hurricanes destroy our infrastructure, civic buildings, public amenities, and homes. These disasters create problems of homelessness, but they also create environments within the city that are unlivable due to a lack of electricity and potable water. People displaced by disasters often find themselves living in a government- or non-profit-run evacuation shelter, at the mercy of bureaucratic organizations for assistance to begin the recovery process. People forced to evacuate neighborhoods where they have perhaps been established for decades often also lose their ability to commute to work (if their employer still exists) as well as their ability to attend school. These shelter environments are repurposed public buildings like schools and sports stadiums, which become the temporary home of sometimes tens of thousands of people. Due to the social and political diversity and the recent collective trauma of the shelter residents, these environments become high-stress and potentially dangerous places. Because shelters can’t stay open forever, government organizations and nonprofits have a number of programs designed to get shelter residents to other forms of housing. FEMA can provide temporary sheltering in a hotel up to two years (for those who qualify) while organizations like the Red Cross can help find alternative housing solutions, and Catholic Charities can provide transportation to go even as far as the next state over to stay with family. Even with all of this assistance, circumstances arise where a certain margin of shelter residents struggle to move on to recovery before the shelter closes. This population mainly consists of people with disabilities, the elderly, and those who were homeless pre-disaster. Due to extenuating circumstances, these people have very little means to recover from disasters and there are limited transitional housing options for them. The author\u27s thesis situates itself within this issue of transitional housing and seeks to find a solution that can accommodate this often marginalized population. The thesis claims are as follows: 1. Every person after a disaster is entitled to shelter in some way, shape, or form 2. This shelter should be adequate in space and amenity to support the individual or group utilizing it 3. People should be made to feel safe, comfortable, and respected 4. Individuals with special needs and disabilities should be made to feel included in the solution, not like they are taking up extra resources

Why does research in finance have so little impact?

The quantity of finance research has grown enormously over the past two decades, yet questions remain over its breadth and ability to benefit the economy and society beyond academia. Using multisource data, we argue that individual and institutional incentives have fostered insularity and a consequent homogeneity in the discipline. We examine the characteristics of research that is published and cited in the leading field journals in finance, arguing that the work has become abstract and unrelated to real world issues. The work published in the ‘top’ journals makes increasing use of US data, even where the researchers are drawn from different countries. Using information from impact assessment, publication patterns, and grant capture, we illustrate that this narrow agenda lacks relevance to the financial services sector, the economy or wider society compared to other areas of business and management research. In particular, we highlight the relative absence of research on ethics in academic finance and discuss the likely consequences for the discipline including its relevance to society

Gender and the evaluation of research

This study examines if and how gender relates to research evaluation via panel assessment and journal ratings lists. Using data from UK business schools we find no evidence that the proportion of women in a submission for panel assessment affected the score received by the submitting institution. However, we do find that women on average receive lower scores according to some journal ratings lists. There are important differences in the rated quality of journals that men and women publish in across the sub-disciplines with men publishing significantly more research in the highest rated accountancy, information management and strategy journals. In addition, women who are able to utilise networks to co-author with individuals outside their institution are able to publish in higher-rated journals, although the same is not true for men; women who are attributed with “individual staff circumstances” (e.g. maternity leave or part-time working) have lower scores according to journal ratings lists

Emotional valence and arousal affect reading in an interactive way: neuroimaging evidence for an approach-withdrawal framework

A growing body of literature shows that the emotional content of verbal material affects reading, wherein emotional words are given processing priority compared to neutral words. Human emotions can be conceptualised within a two-dimensional model comprised of emotional valence and arousal (intensity). These variables are at least in part distinct, but recent studies report interactive effects during implicit emotion processing and relate these to stimulus-evoked approach-withdrawal tendencies. The aim of the present study was to explore how valence and arousal interact at the neural level, during implicit emotion word processing. The emotional attributes of written word stimuli were orthogonally manipulated based on behavioural ratings from a corpus of emotion words. Stimuli were presented during an fMRI experiment while 16 participants performed a lexical decision task, which did not require explicit evaluation of a word's emotional content. Results showed greater neural activation within right insular cortex in response to stimuli evoking conflicting approach-withdrawal tendencies (i.e., positive high-arousal and negative low-arousal words) compared to stimuli evoking congruent approach vs. withdrawal tendencies (i.e., positive low-arousal and negative high-arousal words). Further, a significant cluster of activation in the left extra-striate cortex was found in response to emotional than neutral words, suggesting enhanced perceptual processing of emotionally salient stimuli. These findings support an interactive two-dimensional approach to the study of emotion word recognition and suggest that the integration of valence and arousal dimensions recruits a brain region associated with interoception, emotional awareness and sympathetic functions

The South African guidelines on enuresis-2017

Introduction: Enuresis (or Nocturnal Enuresis) is defined as discreet episodes of urinary incontinence during sleep in children over 5 years of age in the absence of congenital or acquired neurological disorders. Recommendations: Suggestions and recommendations are made on the various therapeutic options available within a South African context. These therapeutic options include; behavioural modification, pharmaceutical therapy [Desmospressin (DDAVP), Anticholinergic (ACh) Agents, Mirabegron (beta 3-adrenoreceptor agonists), and Tricyclic Antidepressants (TCA)], alternative treatments, complementary therapies, urotherapy, alarm therapy, psychological therapy and biofeedback. The role of the Bladder Diary, additional investigations and Mobile Phone Applications (Apps) in enuresis is also explored. Standardised definitions are also outlined within this document. Conclusion: An independent, unbiased, national evaluation and treatment guideline based on the pathophysiological subcategory is proposed using an updated, evidence based approach. This Guideline has received endorsement from the South African Urological Association, Enuresis Academy of South Africa and further input from international experts within the field

Design, recruitment, and retention of African-American smokers in a pharmacokinetic study

<p>Abstract</p> <p>Background</p> <p>African-Americans remain underrepresented in clinical research despite experiencing a higher burden of disease compared to all other ethnic groups in the United States. The purpose of this article is to describe the study design and discuss strategies used to recruit and retain African-American smokers in a pharmacokinetic study.</p> <p>Methods</p> <p>The parent study was designed to evaluate the differences in the steady-state concentrations of bupropion and its three principal metabolites between African-American menthol and non-menthol cigarette smokers. Study participation consisted of four visits at a General Clinical Research Center (GCRC) over six weeks. After meeting telephone eligibility requirements, phone-eligible participants underwent additional screening during the first two GCRC visits. The last two visits (pharmacokinetic study phase) required repeated blood draws using an intravenous catheter over the course of 12 hours.</p> <p>Results</p> <p>Five hundred and fifteen African-American smokers completed telephone screening; 187 were phone-eligible and 92 were scheduled for the first GCRC visit. Of the 81 who attended the first visit, 48 individuals were enrolled in the pharmacokinetic study, and a total of 40 individuals completed the study (83% retention rate).</p> <p>Conclusions</p> <p>Although recruitment of African-American smokers into a non-treatment, pharmacokinetic study poses challenges, retention is feasible. The results provide valuable information for investigators embarking on non-treatment laboratory-based studies among minority populations.</p

Identification and Molecular Characterization of a New Ovarian Cancer Susceptibility Locus at 17q21.31

Epithelial ovarian cancer (EOC) has a heritable component that remains to be fully characterized. Most identified common susceptibility variants lie in non-protein-coding sequences. We hypothesized that variants in the 3 ′ untranslated region at putative microRNA (miRNA) binding sites represent functional targets that influence EOC susceptibility. Here, we evaluate the association between 767 miRNA binding site single nucleotide polymorphisms (miRSNPs) and EOC risk in 18,174 EOC cases and 26,134 controls from 43 studies genotyped through the Collaborative Oncological Gene-environment Study. We identify several miRSNPs associated with invasive serous EOC risk (OR=1.12, P =10−8 ) mapping to an inversion polymorphism at 17q21.31. Additional genotyping of non-miRSNPs at 17q21.31 reveals stronger signals outside the inversion ( P =10−10 ). Variation at 17q21.31 associates with neurological diseases, and our collaboration is the first to report an association with EOC susceptibility. An integrated molecular analysis in this region provides evidence for ARHGAP27 and PLEKHM1 as candidate EOC susceptibility genes

Moving in the anthropocene: global reductions in terrestrial mammalian movements

Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects not only population persistence but also ecosystem processes such as predator-prey interactions, nutrient cycling, and disease transmission

Frontotemporal dementia and its subtypes: a genome-wide association study

SummaryBackground Frontotemporal dementia (FTD) is a complex disorder characterised by a broad range of clinical manifestations, differential pathological signatures, and genetic variability. Mutations in three genes—MAPT, GRN, and C9orf72—have been associated with FTD. We sought to identify novel genetic risk loci associated with the disorder. Methods We did a two-stage genome-wide association study on clinical FTD, analysing samples from 3526 patients with {FTD} and 9402 healthy controls. To reduce genetic heterogeneity, all participants were of European ancestry. In the discovery phase (samples from 2154 patients with {FTD} and 4308 controls), we did separate association analyses for each {FTD} subtype (behavioural variant FTD, semantic dementia, progressive non-fluent aphasia, and {FTD} overlapping with motor neuron disease FTD-MND), followed by a meta-analysis of the entire dataset. We carried forward replication of the novel suggestive loci in an independent sample series (samples from 1372 patients and 5094 controls) and then did joint phase and brain expression and methylation quantitative trait loci analyses for the associated (p&lt;5 × 10−8) single-nucleotide polymorphisms. Findings We identified novel associations exceeding the genome-wide significance threshold (p&lt;5 × 10−8). Combined (joint) analyses of discovery and replication phases showed genome-wide significant association at 6p21.3, \{HLA\} locus (immune system), for rs9268877 (p=1·05 × 10−8; odds ratio=1·204 95% \{CI\} 1·11–1·30), rs9268856 (p=5·51 × 10−9; 0·809 0·76–0·86) and rs1980493 (p value=1·57 × 10−8, 0·775 0·69–0·86) in the entire cohort. We also identified a potential novel locus at 11q14, encompassing RAB38/CTSC (the transcripts of which are related to lysosomal biology), for the behavioural \{FTD\} subtype for which joint analyses showed suggestive association for rs302668 (p=2·44 × 10−7; 0·814 0·71–0·92). Analysis of expression and methylation quantitative trait loci data suggested that these loci might affect expression and methylation in cis. Interpretation Our findings suggest that immune system processes (link to 6p21.3) and possibly lysosomal and autophagy pathways (link to 11q14) are potentially involved in FTD. Our findings need to be replicated to better define the association of the newly identified loci with disease and to shed light on the pathomechanisms contributing to FTD.
