Magnets e turnarounds escolares: Revisitando políticas para promover escolas diversificadas e eqüitativas

This case study examines how magnet school and school turnaround processes can work together to promote desegregation and improvement. Based on cross-case analysis of three magnet schools undergoing turnarounds, this study draws on data from the 2010 federal Magnet Schools Assistance Program grant and qualitative fieldwork through observations, interviews, and focus groups. In academically struggling schools with high concentrations of students of color and low-income students, successful magnet turnarounds involve changes across many aspects of the schools. While the local context is essential for shaping the magnet turnaround process, these three schools reveal common ways in which participants viewed their schools as successful turnarounds, the elements that supported success, and the challenges that magnets undergoing a turnaround are likely to face. Participants’ perceptions of a successful turnaround were based on increasing family interest and increasing racial and economic diversity, as well as improvements in curriculum and instruction, school culture, and academic achievement. This study helps broaden our definition of a school turnaround beyond higher test scores and reminds us of the origins of the concept, which revolved around desegregation. Lessons from the sites suggest that rather than closing underperforming or under-enrolled schools, districts should consider magnet schools as a turnaround approach.Este estudio de casos examina cómo los procesos de turnaround (recuperación) de escuela y escuela de magnet pueden trabajar juntos para promover la desregulación y la mejora. Con base en el análisis cruzado de tres escuelas de magnet en recuperación, este estudio se basa en datos del subsidio federal del Programa de Asistencia de las Escuelas Magnet y en el trabajo de campo cualitativo por medio de observaciones, entrevistas y grupos focales. En escuelas con dificultades académicas, con altas concentraciones de alumnos de color y alumnos de bajos ingresos, los turnos de éxito exitosos de los asociados involucra cambios en muchos aspectos de las escuelas. Aunque el contexto local es esencial para moldear el proceso de recuperación del magnet, estas tres escuelas revelan maneras comunes por las cuales los participantes veían sus escuelas como retornos exitosos, los elementos que sostenían el éxito y los desafíos que los imanes pasando por un giro probablemente se enfrentaría. Las percepciones de los participantes de un giro exitoso se basaron en el interés creciente de la familia y en el aumento de la diversidad racial y económica, así como mejoras en el currículo y la enseñanza, la cultura escolar y el desempeño académico. Este estudio ayuda a ampliar nuestra definición de un giro en la escuela más allá de los resultados de las pruebas más altas y nos recuerda los orígenes del concepto, que giraba en torno a la decesión. Las lecciones de los sitios sugieren que, en lugar de cerrar escuelas de bajo rendimiento o con bajo nivel de matriculación, los distritos deberían considerar las escuelas magnetcomo un enfoque de recuperación.Este estudo de caso examina como os processos de turnaround (recuperação) de escola e escola de magnet podem trabalhar juntos para promover a dessegregação e a melhoria.

Child Temperamental Regulation and Classroom Quality in Head Start: Considering the Role of Cumulative Economic Risk

There is growing recognition that cumulative economic risk places children at higher risk for depressed academic competencies (Crosnoe & Cooper, 2010; NCCP, 2008; Sameroff, 2000). Yet, children’s temperamental regulation and the quality of the early childhood classroom environment have been associated with better academic skills. This study is an examination of prekindergarten classroom quality (instructional support, emotional support, organization) as a moderator between temperamental regulation and early math and literacy skills for children at varying levels of cumulative economic risk. The sample includes children enrolled in Head Start programs drawn from the FACES 2009 study. Three main findings emerged. First, for lower and highest risk children, more instructional support was associated with better math performance when children had high levels of temperamental regulation but poorer performance when children had low temperamental regulation. Second, among highest risk children, low instructional support was protective for math performance for children with low temperamental regulation and detrimental for those with high temperamental regulation. Third, for highest risk children, high classroom organization predicted better literacy scores for those with high temperamental regulation. Children with low temperamental regulation were expected to perform about the same, regardless of the level of classroom organization. Implications are discussed

Coastal Ice-Core Record of Recent Northwest Greenland Temperature and Sea-Ice Concentration

Coastal ice cores provide an opportunity to investigate regional climate and sea-ice variability in the past to complement hemispheric-scale climate reconstructions from ice-sheet-interior ice cores. Here we describe robust proxies of Baffin Bay temperature and sea-ice concentration from the coastal 2Barrel ice core collected in the Thule region of northwest Greenland. Over the 1990–2010 record, 2Barrel annually averaged methanesulfonic acid (MSA) concentrations are significantly correlated with May–June Baffin Bay sea-ice concentrations and summer temperatures. Higher MSA is observed during warmer years with less sea ice, indicative of enhanced primary productivity in Baffin Bay. Similarly, 2Barrel annually averaged deuterium excess (d-excess) values are significantly correlated with annual Baffin Bay sea-ice concentrations and summer and annual temperatures. Warm (cool) years with anomalously low (high) sea-ice concentration are associated with proportionally more (less) low-d-excess Baffin Bay moisture at the ice-core site. Multilinear regression models incorporating 2Barrel MSA, d-excess and snow accumulation account for 38–51% of the Baffin Bay sea-ice and temperature variance. The annual temperature model is significantly correlated with temperatures throughout most of Greenland and eastern Arctic Canada due to the strong influence of the North Atlantic Oscillation and Atlantic Multidecadal Oscillation

Negative information seeking experiences of long-term prostate cancer survivors

Purpose Many prostate cancer survivors have lasting symptoms and disease-related concerns for which they seek information. To understand survivors’ information seeking experiences, we examined the topics of their information searches, their overall perceptions of the search, and perceptions of their health information seeking self-efficacy (i.e., confidence in their ability to obtain information). We hypothesized that negative search experiences and lower health information seeking self-efficacy would be associated with certain survivor characteristics such as non-white race, low income, and less education. Methods This was a retrospective study using data from the Michigan Prostate Cancer Survivor Study (state-based survey of long-term prostate cancer survivor outcomes, N=2,499, response rate = 38%). Participants recalled their last search for information and reported the topics and overall experience. We conducted multivariable regression to examine the association between survivor characteristics and the information-seeking experience. Results Nearly a third (31.7%) of prostate cancer survivors (median age of 76 years and 9 years since diagnosis) reported having negative information seeking experiences when looking for information. However, only 13.4% reported having low health information seeking self-efficacy. Lower income and less education were both significantly associated with negative information seeking experiences. Conclusions Our findings suggest that many long-term prostate cancer survivors have negative experiences when searching for information, and lower income and less education were survivor factors related to negative information seeking experiences. Implications for cancer survivors We advocate for ongoing, information needs assessment at the point-of-care as the survivorship experience progresses to assess and potentially improve survivors’ quality of life

Racial/ethnic differences in adequacy of information and support for women with breast cancer

BACKGROUND. Providing breast cancer patients with needed information and support is an essential component of quality care. This study investigated racial/ethnic variations in the information received and in the availability of peer support. METHODS. In total, 1766 women who were diagnosed with nonmetastatic breast cancer and reported to the Los Angeles County Surveillance, Epidemiology, and End Results registry from June 2005 to May 2006 were mailed a survey after initial treatment. Among accrued cases, 96.2% met eligibility criteria (n = 1698), and 72% completed the survey. Race/ethnicity categories were white, African American, and Latinas (2 categories indicating low or high acculturation, which was determined by using the Short Acculturation Scale for Hispanics). Outcomes included receipt and need for treatment-related and survivorship-related information, difficulty understanding information, and support from women with breast cancer. RESULTS. More women reported receiving treatment-related information than survivorship-related information. After adjusting for sociodemographic, clinical, and treatment factors, a higher percentage of low acculturated Latina women desired more information on treatment-related and survivorship-related issues ( P < .001). Significantly more Latina low acculturated women than white women reported difficulty understanding written materials, with 74.5% requiring help from others. A higher percentage of all minority groups compared with whites reported no contact with other women with breast cancer ( P < .05) and reported less contact through family/friends ( P < .05). Women rated the benefit of talking to other women high, particularly with emotional issues. CONCLUSIONS. Continued efforts to provide culturally appropriate information and support needs to women with breast cancer are necessary to achieve quality care. Latinas with low acculturation reported more unmet information and care support needs than women in other racial/ethnic groups.

A molecular cell biology toolkit for the study of meiosis in the silkworm Bombyx mori

Meiosis is usually described as 4 essential and sequential processes: (1) homolog pairing; (2) synapsis, mediated by the synaptonemal complex; (3) crossing over; and (4) segregation. In this canonical model, the maturation of crossovers into chiasmata plays a vital role in holding homologs together and ensuring their segregation at the first meiotic division. However, Lepidoptera (moths and butterflies) undergo 3 distinct meiotic processes, only one of which is canonical. Lepidoptera males utilize 2 meiotic processes: canonical meiosis that produces nucleated fertile sperm, and a noncanonical meiosis that produces anucleated nonfertile sperm which are nonetheless essential for reproduction. Lepidoptera females, which carry heteromorphic sex chromosomes, undergo a completely achiasmate (lacking crossovers) meiosis, thereby requiring an alternative mechanism to ensure proper homolog segregation. Here, we report that the development of a molecular cell biology toolkit designed to properly analyze features of meiosis, including the synaptonemal complex structure and function, in the silkworm Bombyx mori. In addition to standard homology searches to identify Bombyx orthologs of known synaptonemal complex encoding genes, we developed an ortholog discovery app (Shinyapp) to identify Bombyx orthologs of proteins involved in several meiotic processes. We used this information to clone genes expressed in the testes and then created antibodies against their protein products. We used the antibodies to confirm the localization of these proteins in normal male spermatocytes, as well as using in vitro assays to confirm orthologous interactions. The development of this toolkit will facilitate further study of the unique meiotic processes that characterize meiosis in Lepidoptera.</p

Per-treatment post-hoc analysis of clinical trial outcomes with Tolvaptan in autosomal dominant polycystic kidney disease

Introduction: In pivotal trials of patients with autosomal dominant polycystic kidney disease at risk of rapid progression, tolvaptan slowed estimated glomerular filtration rate (eGFR) decline in early-to-moderate (TEMPO 3:4 [NCT00428948]) and moderate-to-late stage (REPRISE [NCT02160145]) chronic kidney disease (CKD). Discontinuation was less frequent in REPRISE (15.0%) than TEMPO 3:4 (23.0%), given that in REPRISE, only subjects who tolerated tolvaptan 60/30 mg daily initiated the double-blind phase. We evaluated whether the greater treatment effect in REPRISE was attributable to different completion rates. Methods: We conducted post hoc analyses of TEMPO 3:4 and REPRISE completers, defined as subjects who took trial drug to the end of the treatment period in TEMPO 3:4 (3 years) or REPRISE (1 year). Efficacy (rate of change in eGFR for tolvaptan versus placebo) was analyzed as in each trial. Subjects from TEMPO 3:4 and REPRISE were also matched by propensity score for age, gender, and baseline eGFR to explore potential additional determinants of treatment effect. Results: The annualized tolvaptan treatment effect in TEMPO 3:4 completers (difference versus placebo of 0.98 mL/min/1.73 m2/year) and REPRISE completers (difference of 1.23) was similar to that of the respective total trial populations (TEMPO 3:4: 0.94; REPRISE: 1.27). The treatment effect of tolvaptan was also similar between matched subjects. Conclusion: Greater treatment completion rate did not drive greater treatment effect in REPRISE. The more advanced CKD of REPRISE subjects may be more relevant. More rapid decline in kidney function in later-stage CKD enabled the effects of tolvaptan to be more easily discerned

Randomised Trial to Evaluate the Effectiveness and Impact of Offering Postvisit Decision Support and Assistance in Obtaining Physician-Recommended Colorectal Cancer Screening: The e-Assist: Colon Health Study - A Protocol Study

INTRODUCTION: How to provide practice-integrated decision support to patients remains a challenge. We are testing the effectiveness of a practice-integrated programme targeting patients with a physician recommendation for colorectal cancer (CRC) screening. METHODS AND ANALYSIS: In partnership with healthcare teams, we developed \u27e-assist: Colon Health\u27, a patient-targeted, postvisit CRC screening decision support programme. The programme is housed within an electronic health record (EHR)-embedded patient portal. It leverages a physician screening recommendation as the cue to action and uses the portal to enrol and intervene with patients. Programme content complements patient-physician discussions by encouraging screening, addressing common questions and assisting with barrier removal. For evaluation, we are using a randomised trial in which patients are randomised to receive e-assist: Colon Health or one of two controls (usual care plus or usual care). Trial participants are average-risk, aged 50-75 years, due for CRC screening and received a physician order for stool testing or colonoscopy. Effectiveness will be evaluated by comparing screening use, as documented in the EHR, between trial enrollees in the e-assist: Colon Health and usual care plus (CRC screening information receipt) groups. Secondary outcomes include patient-perceived benefits of, barriers to and support for CRC screening and patient-reported CRC screening intent. The usual care group will be used to estimate screening use without intervention and programme impact at the population level. Differences in outcomes by study arm will be estimated with hierarchical logit models where patients are nested within physicians. ETHICS AND DISSEMINATION: All trial aspects have been approved by the Institutional Review Board of the health system in which the trial is being conducted. We will disseminate findings in diverse scientific venues and will target clinical and quality improvement audiences via other venues. The intervention could serve as a model for filling the gap between physician recommendations and patient action. TRIAL REGISTRATION NUMBER: NCT02798224; Pre-results

Development and psychometric properties of a brief measure of subjective decision quality for breast cancer treatment

Abstract Background Breast cancer patients face several preference-sensitive treatment decisions. Feelings such as regret or having had inadequate information about these decisions can significantly alter patient perceptions of recovery and recurrence. Numerous objective measures of decision quality (e.g., knowledge assessments, values concordance measures) have been developed; there are far fewer measures of subjective decision quality and little consensus regarding how the construct should be assessed. The current study explores the psychometric properties of a new subjective quality decision measure for breast cancer treatment that could be used for other preference sensitive decisions. Methods 320 women aged 20–79 diagnosed with AJCC stage 0 – III breast cancer were surveyed at two cancer specialty centers. Decision quality was assessed with single items representing six dimensions: regret, satisfaction, and fit as well as perceived adequacy of information, time, and involvement. Women rated decision quality for their overall treatment experience and surgery, chemotherapy, and radiation decisions separately. Principle components was used to explore factor structure. After scales were formed, internal consistency was computed using Cronbach’s alpha. The association of each of the four final scales with patient characteristics scores was examined by Pearson correlation. Results For overall breast cancer treatment as well as surgery, chemotherapy, and radiation decisions, the six items yielded a single factor solution. Factor loadings of the six decision items were all above .45 across the overall and treatment-specific scales, with the exception of “Right for You” for chemotherapy and radiation. Internal consistency was 0.77, 0.85, 0.82, and 0.78 for the overall, surgery, chemotherapy, and radiation decision quality scales, respectively. Conclusions Our measure of subjective appraisal of breast cancer treatment decisions includes 5 related elements; regret and satisfaction as well as perceived adequacy of information, time, and involvement. Future research is needed to establish norms for the measure as is further psychometric testing, particularly to examine how it is associated with outcomes such as quality of life, psychological coping and objective decision quality.http://deepblue.lib.umich.edu/bitstream/2027.42/109727/1/12911_2014_Article_110.pd

Risk factors of different hemoplasma species infections in cats

Background: Hemoplasma species (spp.) commonly cause infections in cats worldwide. However, data on risk factors for infections are limited. The aim of this study was to determine the prevalence of hemoplasma spp. infections in cats in Southern Germany and to assess risk factors associated with infection. Results: DNA was extracted from blood samples of 479 cats presented to different veterinary hospitals for various reasons. DNA of feline hemoplasmas was amplified by use of a previously reported PCR assay. Direct sequencing was used to confirm all purified amplicons and compared to hemoplasma sequences reported in GenBank. Results were evaluated in relation to the age, sex, housing conditions, feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) status of the cats. The overall hemoplasma prevalence rate was 9.4% (45/479;95% CI: 7.08-12.36). 'Candidatus Mycoplasma (M.) haemominutum' (Mhm) DNA was amplified from 42 samples, M. haemofelis from 2, and M. haemocanis from 1 sample. There was a significantly higher risk of hemoplasma infection in cats from multi-cat households, in outdoor cats, as well as in cats with FIVinfection and in cats with abortive FeLV infection, but not in cats with progressive or regressive FeLV infection. Conclusions: Mhm infection is common in cats in Southern Germany. Higher prevalence in multi-cat households and associations with FeLV infection likely reflect the potential for direct transmission amongst cats. Outdoor access, male gender, and FIV infection are additional risk factors that might relate to aggressive interactions and exposure to vectors
