Iniciativas políticas: Examinando as práticas de múltiplos distritos superintendentes
Over the past decade, multiple states have implemented a form of regional school district consolidation referred to as multi-district unions. Their organizational structure enables districts to retain individual school boards within regional local education agencies, all of which are overseen by a superintendent and a central board. However, no empirical research has been conducted to date on the ensuing work of multi-district superintendents. In our exemplary case study, we analyze time records, interviews, and observations to understand the role allocations and work of one multi-district superintendent. We find the division of time and ensuing responsibilities of the multi-district superintendent is predominantly political to the organizational structure of the union, and we conclude with implications for policy and practice.

Evaluation of the GE Foundation-Supported Coaching & Demonstration Schools Initiative in Erie Public Schools, SY 2012-2013
This evaluation report summarizes the evidence of the implementation and early impacts of the General Electric Foundation’s (GEF) Demonstration Schools Initiative in the Erie Public School district (EPS) conducted by the Consortium for Policy Research in Education (CPRE) during the 2012-2013 school year. The Demonstration Schools Initiative provided intensive support to four schools (two elementary, one middle, and one high) implementing the Common Core State Standards (CCSS) in mathematics and English language arts. Concurrently during the 2012- 2013 school year, EPS also continued their implementation of another GEF-supported initiative— the Coaching Initiative—using a cadre of instructional coaches in mathematics, science, and ELA for the other schools in the district.
In both the Coaching and Demonstration School Initiatives, instructional coaches are key agents of change. Their function is to target and customize the support needed at the building, grade, and teacher levels to shift teachers’ understanding and practice to align to the CCSS. For the Demonstration Schools Initiative, coaches also focused much of their time trying to develop professional learning communities (PLCs) within their schools.
This evaluation was designed to answer three overarching questions: Did teachers in the Demonstration Schools gain more knowledge of the CCSS as a result of their participation in the GEF-supported initiative? What were the impacts of the initiative for the teachers in the GEF- Foundation supported Demonstration Schools compared to the rest of the district? How did teachers perceive their respective coaches throughout the district
The Masculinized Work of Energy Development: Unequal Opportunities and Risks for Women in Pennsylvania Shale Gas Boomtown Communities
The proliferation of unconventional shale gas development has revived scholarly interest in the impacts of rapid industrial development on communities, schools, policies and politics, public health, the environment, and economic growth. However, with few exceptions, close examinations of the gendered structure of opportunity within areas experiencing rapid shale gas development have largely been absent from this literature. This article uses key informant interview data from low income men and women, as well as from social service providers within Pennsylvania communities heavily affected by shale gas development. In contrast to assertions that shale gas development will yield broad-based economic development impacts for the region, the experiences of the participants in this study suggest a more segmented economic opportunity structure coupled with the creation of new gendered economic and social vulnerabilities as class and gender intersect to create decreased economic opportunities and increased social vulnerabilities for low-income women
Daily Rhythms of Plasma Melatonin, but Not Plasma Leptin or Leptin mRNA, Vary between Lean, Obese and Type 2 Diabetic Men
Melatonin and leptin exhibit daily rhythms that may contribute towards changes in metabolic physiology. It remains unclear, however, whether this rhythmicity is altered in obesity or type 2 diabetes (T2DM). We tested the hypothesis that 24-hour profiles of melatonin, leptin and leptin mRNA are altered by metabolic status in laboratory conditions. Men between 45–65 years old were recruited into lean, obese-non-diabetic or obese-T2DM groups. Volunteers followed strict sleep-wake and dietary regimes for 1 week before the laboratory study. They were then maintained in controlled light-dark conditions, semi-recumbent posture and fed hourly iso-energetic drinks during wake periods. Hourly blood samples were collected for hormone analysis. Subcutaneous adipose biopsies were collected 6-hourly for gene expression analysis. Although there was no effect of subject group on the timing of dim light melatonin onset (DLMO), nocturnal plasma melatonin concentration was significantly higher in obese-non-diabetic subjects compared to weight-matched T2DM subjects (p<0.01) and lean controls (p<0.05). Two T2DM subjects failed to produce any detectable melatonin, although did exhibit plasma cortisol rhythms comparable to others in the group. Consistent with the literature, there was a significant (p<0.001) effect of subject group on absolute plasma leptin concentration and, when expressed relative to an individual’s 24-hour mean, plasma leptin showed significant (p<0.001) diurnal variation. However, there was no difference in amplitude or timing of leptin rhythms between experimental groups. There was also no significant effect of time on leptin mRNA expression. Despite an overall effect (p<0.05) of experimental group, post-hoc analysis revealed no significant pair-wise effects of group on leptin mRNA expression. Altered plasma melatonin rhythms in weight-matched T2DM and non-diabetic individuals supports a possible role of melatonin in T2DM aetiology. However, neither obesity nor T2DM changed 24-hour rhythms of plasma leptin relative to cycle mean, or expression of subcutaneous adipose leptin gene expression, compared with lean subjects
Association of the PHACTR1/EDN1 genetic locus with spontaneous coronary artery dissection
Background:
Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndromes (ACS) afflicting predominantly younger to middle-aged women. Observational studies have reported a high prevalence of extracoronary vascular anomalies, especially fibromuscular dysplasia (FMD) and a low prevalence of coincidental cases of atherosclerosis. PHACTR1/EDN1 is a genetic risk locus for several vascular diseases, including FMD and coronary artery disease, with the putative causal noncoding variant at the rs9349379 locus acting as a potential enhancer for the endothelin-1 (EDN1) gene.
Objectives:
This study sought to test the association between the rs9349379 genotype and SCAD.
Methods:
Results from case control studies from France, United Kingdom, United States, and Australia were analyzed to test the association with SCAD risk, including age at first event, pregnancy-associated SCAD (P-SCAD), and recurrent SCAD.
Results:
The previously reported risk allele for FMD (rs9349379-A) was associated with a higher risk of SCAD in all studies. In a meta-analysis of 1,055 SCAD patients and 7,190 controls, the odds ratio (OR) was 1.67 (95% confidence interval [CI]: 1.50 to 1.86) per copy of rs9349379-A. In a subset of 491 SCAD patients, the OR estimate was found to be higher for the association with SCAD in patients without FMD (OR: 1.89; 95% CI: 1.53 to 2.33) than in SCAD cases with FMD (OR: 1.60; 95% CI: 1.28 to 1.99). There was no effect of genotype on age at first event, P-SCAD, or recurrence.
Conclusions:
The first genetic risk factor for SCAD was identified in the largest study conducted to date for this condition. This genetic link may contribute to the clinical overlap between SCAD and FMD
Genetic mechanisms of critical illness in COVID-19.
Host-mediated lung inflammation is present1, and drives mortality2, in the critical illness caused by coronavirus disease 2019 (COVID-19). Host genetic variants associated with critical illness may identify mechanistic targets for therapeutic development3. Here we report the results of the GenOMICC (Genetics Of Mortality In Critical Care) genome-wide association study in 2,244 critically ill patients with COVID-19 from 208 UK intensive care units. We have identified and replicated the following new genome-wide significant associations: on chromosome 12q24.13 (rs10735079, P = 1.65 × 10-8) in a gene cluster that encodes antiviral restriction enzyme activators (OAS1, OAS2 and OAS3); on chromosome 19p13.2 (rs74956615, P = 2.3 × 10-8) near the gene that encodes tyrosine kinase 2 (TYK2); on chromosome 19p13.3 (rs2109069, P = 3.98 × 10-12) within the gene that encodes dipeptidyl peptidase 9 (DPP9); and on chromosome 21q22.1 (rs2236757, P = 4.99 × 10-8) in the interferon receptor gene IFNAR2. We identified potential targets for repurposing of licensed medications: using Mendelian randomization, we found evidence that low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease; and transcriptome-wide association in lung tissue revealed that high expression of the monocyte-macrophage chemotactic receptor CCR2 is associated with severe COVID-19. Our results identify robust genetic signals relating to key host antiviral defence mechanisms and mediators of inflammatory organ damage in COVID-19. Both mechanisms may be amenable to targeted treatment with existing drugs. However, large-scale randomized clinical trials will be essential before any change to clinical practice
