Supporting the Literacy Development of Striving Readers through Competing Theoretical Perspectives

Abstract In this paper, we present educators with the theoretical underpinnings of competing pedagogical approaches to literacy instruction. Given the recent push by many states to universally screen students in the early grades for dyslexia and institute phonics-only standards, we seek to reiterate the importance of a balanced approach. Our purpose is to explain how two contrasting orientations regarding the reading process can together form a framework for providing the best literacy education possible for all students, especially striving readers. We explore both the cognitive information-processing and constructivist perspectives and examine prominent models and theories that inform each approach. Recent research showcasing effective instructional strategies that have emerged from both perspectives is presented, and practical ways that both perspectives find expression in effective classroom practice, including meaningful use of technology, are also delineated. Last, we provide explicit case studies illustrating what literacy support looks like when competing information-processing and constructivist perspectives are blended and how teachers can practically utilize dual approaches to support their most vulnerable students. We join our voices with those of other scholars who call on educators to embrace a holistic, balanced approach to literacy instruction that is informed by various perspectives in their effort to reach striving readers. Keywords: balanced literacy, effective literacy instruction, striving reader

Changing the Principal Supervisor Role to Better Support Principals: Evidence from the Principal Supervisor Initiative

The principal supervisor job has traditionally revolved around administration, operations and compliance, but as principals have increasingly been called on in recent years to concentrate on supporting high-quality teaching, the idea of a complementary makeover of the supervisor job has gained attention. In 2014, with funding from The Wallace Foundation, six large school districts around the country embarked on a four-year, $24-million initiative to redesign the supervisor position so it focused primarily on supporting principals in their role as instructional leaders.This report, which looks at the final year and the effects of the Principal Supervisor Initiative, concludes that the effort succeeded in changing the job so that it centered on developing and evaluating principals to help them promote effective teaching and learning in their schools. Over the course of the initiative, principals' ratings of their supervisors' effectiveness rose from 3.88 to 4.10 on a scale of 1-to-5, a statistically significant increase. Principals reported greater frequency of supervisor practices to develop school leadership—such as helping principals with data analysis, providing them with useful feedback and working with them to assess teacher effectiveness

Organizational Characteristics of High- and Low-Clozapine-Utilization Clinics in the Veterans Health Administration

Objective: Treatment-resistance schizophrenia occurs in 20-30% of patients. Clozapine is the only medication proven effective for treatment-resistant schizophrenia. However, less than 25% of treatment-resistant schizophrenia patients receive clozapine in most settings. Therefore, this study was conducted to identify facilitators and barriers to clozapine use, to inform development of interventions to maximize appropriate clozapine-utilization. Methods: Seventy semi-structured phone interviews were conducted with five high- and five low-utilization VA Medical Centers, from different US regions including urban and rural areas. Interviewees were key informants of clozapine processes, including mental health leadership, psychiatrists, clinical pharmacists and advanced practice nurses. Interviews were analyzed using an emergent thematic strategy to identify barriers and facilitators to clozapine prescribing. Results: Key elements associated with high-utilization included integration of non-physician psychiatric providers and clear organizational processes and infrastructure for treatment of severe mental illness (e.g. clozapine clinics, larger mental health intensive case management services). Low-utilization was associated with lack of champions to support clozapine processes and limited-capacity care systems. Obstacles identified at both high- and low-utilization sites included complex time-consuming paperwork, reliance on few individuals to facilitate processes, and issues related to transportation for patients living far from care facilities. Conclusions: Implementation efforts to organize, streamline and simplify clozapine processes, development of a multidisciplinary clozapine clinic, increasing the size and capacity of existing clinics, and provision of transportation are reasonable targets to increase clozapine utilization

Paradoxical patterns of sinusoidal obstruction syndrome-like liver injury in aged female CD-1 mice triggered by cannabidiol-rich cannabis extract and acetaminophen co-administration

© 2019 The Authors. Environmental Toxicology published by Wiley Periodicals, Inc. Exposure to environmental contaminants and consumption of a high, saturated fatty diet has been demonstrated to promote precursors for metabolic syndrome (hyperglycemia, hyperinsulinemia, and hypertriglyceridemia). The purpose of this study was to determine if exposure to the most prevalent environmental persistent organic pollutants (POPs) would act as causative agents to promote metabolic syndrome independent of dietary intake. We hypothesized that POPs will activate the advanced glycated end-product (AGE)-and receptor for AGE (RAGE) signaling cascade to promote downstream signaling modulators of cardiovascular remodeling and oxidative stress in the heart. At 5-weeks of age nondiabetic (WT) and diabetic (ob/ob) mice were exposed POPs mixtures by oral gavage twice a week for 6-weeks. At the end of 6-weeks, animals were sacrificed and the hearts were taken for biochemical analysis. Increased activation of the AGE-RAGE signaling cascade via POPs exposure resulted in elevated levels of fibroblast differentiation (α-smooth muscle actin) and RAGE expression indicated maladaptive cardiac remodeling. Conversely, the observed decreased superoxide dismutase-1 and -2 (SOD-1 and SOD-2) expression may exacerbate the adverse changes occurring as a result of POPs treatment to reduce innate cardioprotective mechanisms. In comparison, ventricular collagen levels were decreased in mice exposed to POPs. In conclusion, exposure to organic environmental pollutants may intensify oxidative and inflammatory stressors to overwhelm protective mechanisms allowing for adverse cardiac remodeling

Higher incidence of perineal community acquired MRSA infections among toddlers

<p>Abstract</p> <p>Background</p> <p>A six-fold increase in pediatric MRSA infections, prompted us to examine the clinical profile of children with MRSA infections seen at Mercy Children's Hospital, Toledo, Ohio and to characterize the responsible strains.</p> <p>Methods</p> <p>Records were reviewed of pediatric patients who cultured positive for MRSA from June 1 to December 31, 2007. Strain typing by pulsed field gel electrophoresis (PFT) and DiversiLab, SCC<it>mec </it>typing, and PCR-based <it>lukSF-PV </it>gene (encodes Panton-Valentine leukocidin), arginine catabolic mobile element (ACME) and <it>cap</it>5 gene detection was performed.</p> <p>Results</p> <p>Chart review of 63 patients with MRSA infections revealed that 58(92%) were community acquired MRSA (CAMRSA). All CAMRSA were skin and soft tissue infections (SSTI). Twenty five (43%) patients were aged < 3 yrs, 19(33%) aged 4-12 and 14(24%) aged 13-18. Nineteen (76%) of those aged < 3 yrs had higher incidence of perineal infections compared to only 2(11%) of the 4-12 yrs and none of the 13-18 yrs of age. Infections in the extremities were more common in the older youth compared to the youngest children. Overall, there was a significant association between site of the infection and age group (Fisher's Exact p-value < 0.001). All CAMRSA were USA300 PFT, clindamycin susceptible, SCC<it>mec </it>type IVa and <it>lukSF-PV gene </it>positive. Nearly all contained ACME and about 80% were <it>cap</it>5 positive. Of the 58 USA300 strains by PFT, 55(95%) were also identified as USA300 via the automated repetitive sequence-based PCR method from DiversiLab.</p> <p>Conclusions</p> <p>CAMRSA SSTI of the perineum was significantly more common among toddlers and that of the extremities in older children. The infecting strains were all USA300 PFT. Further studies are needed to identify the unique virulence and colonization characteristics of USA300 strains in these infections.</p

Haptoglobin 2 Allele is Associated With Histologic Response to Vitamin E in Subjects With Nonalcoholic Steatohepatitis

Background: Haptoglobin (Hp) genotype has been linked to oxidative stress and response to vitamin E (VitE) in patients with dyslipidemia. Its effect on histological response to VitE in nonalcoholic steatohepatitis (NASH) is unknown. Goals: Our objective was to determine if Hp genotype associates with response to VitE in patients with NASH. Study: A post hoc analysis of 228 patients receiving VitE or placebo in two clinical trials was performed. Regression analysis was used to assess the effect of VitE versus placebo, by Hp genotype (1–1, 2–1, or 2–2), on histologic features and laboratory markers of liver disease, comparing baseline to end of treatment values. An interaction term was included in the regression models to assess differential treatment effect across Hp genotype. Results: Hp 2–2 patients treated with VitE versus placebo showed significant histologic improvement (51% versus 20%, OR=4·2, p=0·006), resolution of steatohepatitis (44% versus 12%, OR=6.2, p=0·009), decrease in NAFLD Activity Score (NAS) (−2·2 versus −0·6, p=0·001), and decrease in liver enzymes alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and γ-glutamyl transpeptidase. Hp 2–1 patients on VitE versus placebo showed improved resolution of steatohepatitis, NAS and liver enzymes. Hp 1–1 patients showed no significant improvement in histology or liver enzymes. VitE had no effect on fibrosis stage in any group. Regression analysis showed incremental benefit of having Hp 2–2 or 2–1 versus 1–1 for all liver enzymes. Conclusion: Hp 2 allele is associated with greater histological and biological improvement in NASH with VitE treatment compared to the Hp 1 allele
