Teaching Advanced Writing: the Critical Essay. A Community Language Learning Based Approach
In this paper I will discuss how I applied my understanding of certain concepts of Community Language Learning to a writing class and specifically to the teaching of the critical essay. In Part One I will describe what we did in the class; in Part Two I will discuss the concepts of Community Language Learning that I was trying to apply in the class and how I was doing so; in the conclusion I will discuss how I see those concepts as being applicable to any class, regardless of the subject matter being taught
Reading Guidance: A Study Based on an Analysis of the Interests, Habits, and Abilities of a Selected Group of Ninth Grade Students at Horace Maynard High School
This study was an evaluation of efforts to stimulate and motivate the development and refinement of the attitudes and habits involved in the personal reading selections of ninth grade students. The specific purpose was to determine the extent to which reading interests can be elevated and broadened under a carefully planned reading guidance program. The guidance procedures used were based on an analysis of the reading interests and abilities of a selected group of students.
The problem of this investigation was to determine the following:
1. Into what categories do the personal reading interests and reading abilities of these students fall?
2. What relationship do sex and intelligence have to reading interests and preferences?
3. To what extent does the home environment affect achievement in reading and the development of literary taste as reflected by the reading choices of the students?
4. As a result of the planned reading guidance program, is there evidence of broadened interests and elevated reading tastes in (a) the quantity of books read, (b) a wider range of subjects selected, and (c) the quality and maturity level of books chosen
Nurse Researchers in Children\u27s Hospitals
Little is known about the role of nurse researchers (NRs) and the structure of nursing research programs in children\u27s hospitals in the United States. This descriptive study obtained survey data from 33 NRs. Data suggest that the NR role is emerging and has both commonalities and unique components when compared with the previous studies of NRs in adult hospitals. Most participants have been in their position for less than 4 years. Conducting research, having staff development related to research, and facilitating evidence-based practice or research were common responsibilities. The structure of nursing research programs impacts both the NRs and the program outcomes
Health service pathways for patients with chronic leg ulcers: identifying effective pathways for facilitation of evidence based wound care
Background: Chronic leg ulcers cause long term ill-health for older adults and the condition places a significant burden on health service resources. Although evidence on effective management of the condition is available, a significant evidence-practice gap is known to exist, with many suggested reasons e.g. multiple care providers, costs of care and treatments. This study aimed to identify effective health service pathways of care which facilitated evidence-based management of chronic leg ulcers.
Methods: A sample of 70 patients presenting with a lower limb leg or foot ulcer at specialist wound clinics in Queensland, Australia were recruited for an observational study and survey. Retrospective data were collected on demographics, health, medical history, treatments, costs and health service pathways in the previous 12 months. Prospective data were collected on health service pathways, pain, functional ability, quality of life, treatments, wound healing and recurrence outcomes for 24 weeks from admission.
Results: Retrospective data indicated that evidence based guidelines were poorly implemented prior to admission to the study, e.g. only 31% of participants with a lower limb ulcer had an ABPI or duplex assessment in the previous 12 months. On average, participants accessed care 2â3 times/week for 17 weeks from multiple health service providers in the twelve months before admission to the study clinics. Following admission to specialist wound clinics, participants accessed care on average once per week for 12 weeks from a smaller range of providers. The median ulcer duration on admission to the study was 22 weeks (range 2â728 weeks). Following admission to wound clinics, implementation of key indicators of evidence based care increased (p < 0.001) and Kaplan-Meier survival analysis found the median time to healing was 12 weeks (95% CI 9.3â14.7). Implementation of evidence based care was significantly related to improved healing outcomes (p < 0.001).
Conclusions: This study highlights the complexities involved in accessing expertise and evidence based wound care for adults with chronic leg or foot ulcers. Results demonstrate that access to wound management expertise can promote streamlined health services and evidence based wound care, leading to efficient use of health resources and improved health
Cost-Effectiveness of an Intervention to Reduce Emergency Re-Admissions to Hospital among Older Patients
Background. The objective is to estimate the cost-effectiveness of an intervention that reduces hospital readmission among older people at high risk. A cost-effectiveness model to estimate the costs and health benefits of the intervention was implemented. Methodology/Principal Findings. The model used data from a randomised controlled trial conducted in an Australian tertiary metropolitan hospital. Participants were acute medical admissions aged >65 years with at least one risk factor for readmission: multiple comorbidities, impaired functionality, aged >75 years, 30 recent multiple admissions, poor social support, history of depression. The intervention was a comprehensive nursing and physiotherapy assessment and an individually tailored program of exercise strategies and nurse home visits with telephone follow-up; commencing in hospital and continuing following discharge for 24 weeks. The change to cost outcomes, including the costs of implementing the intervention and all subsequent use of health care services, and, the change to health benefits, represented by quality adjusted life years, were estimated for the intervention as compared to existing practice. The mean change to total costs and quality 38 adjusted life years for an average individual over 24 weeks participating in the intervention were: cost savings of -1,932:1,282) and 0.118 extra quality adjusted life years (95% Bayesian credible interval 0.1:0.136). The mean net41 monetary-benefit per individual for the intervention group compared to the usual care condition was 5,959:$9,995) for the 24 week period. Conclusions/Significance. The estimation model that describes this intervention predicts cost savings and improved health outcomes. A decision to remain with existing practices causes unnecessary costs and reduced health. Decision makers should consider adopting this 46 program for elderly hospitalised patients
Electrostatic repulsion causes anticooperative DNA binding between tumor suppressor ETS transcription factors and JUN-FOS at composite DNA sites
Many different transcription factors (TFs) regulate gene expression in a combinatorial fashion, often by binding in close proximity to each other on composite cis-regulatory DNA elements. Here, we investigated how ETS TFs bind with the AP1 TFs JUN-FOS at composite DNA-binding sites. DNA-binding ability with JUN-FOS correlated with the phenotype of ETS proteins in prostate cancer. We found that the oncogenic ETS-related gene (ERG) and ETS variant (ETV) 1/4/5 subfamilies co-occupy ETS-AP1 sites with JUN-FOS in vitro, whereas JUN-FOS robustly inhibited DNA binding by the tumor suppressors ETS homologous factor (EHF) and SAM pointed domain-containing ETS TF (SPDEF). EHF bound ETS-AP1 DNA with tighter affinity than ERG in the absence of JUN-FOS, possibly enabling EHF to compete with ERG and JUN-FOS for binding to ETS-AP1 sites. Genome-wide mapping of EHF- and ERG-binding sites in prostate epithelial cells revealed that EHF is preferentially excluded from closely spaced ETS-AP1 DNA sequences. Structural modeling and mutational analyses indicated that adjacent positively charged surfaces from EHF and JUN-FOS use electrostatic repulsion to disfavor simultaneous DNA binding. Conservation of positive residues on the JUN-FOS interface identified E74-like ETS TF 1 (ELF1) as an additional ETS TF exhibiting anticooperative DNA binding with JUN-FOS, and we found that ELF1 is frequently down-regulated in prostate cancer. In summary, divergent electrostatic features of ETS TFs at their JUN-FOS interface enable distinct binding events at ETS-AP1 DNA sites, which may drive specific targeting of ETS TFs to facilitate distinct transcriptional programs
African American Women's Perspectives on Breast Cancer: Implications for Communicating Risk of Basal-like Breast Cancer
African American women suffer a higher burden of basal-like breast cancer, an aggressive subtype that has no targeted therapy. While epidemiologic research has identified key prevention strategies, little is known about how best to communicate risk to this population. This study explored womenâs knowledge, beliefs, and attitudes about breast cancer to learn about risk perceptions. Six focus groups with 57 women (ages 18â49) women were conducted in North Carolina. Findings revealed that age, race (especially perceptions of cancer as a âWhite diseaseâ), and lack of family history of breast cancer contributed to womenâs perceptions of low breastcancer susceptibility. Perceptions of low risk were also attributed to conflicting risk information from family, media, and health providers. Women had little knowledge about breast cancer subtypes, but emphasized that health communications should be personally relevant, culturally appropriate, and convenient. These study findings will assist in developing health communication tools that encourage prevention
Report from the âWhat is Open?â Workgroup
The scholarly communityâs current definition of âopenâ captures only some of the attributes of openness that exist across different publishing models and content types. Open is not an end in itself, but a means for achieving the most effective dissemination of scholarship and research. We suggest that the different attributes of open exist along a broad spectrum and propose an alternative way of describing and evaluating openness based on four attributes: discoverable, accessible, reusable, and transparent. These four attributes of openness, taken together, form the draft âDART Framework for Open Access.â This framework can be applied to both research artifacts as well as research processes. We welcome input from the broader scholarly community about this framework
Resequencing Candidate Genes Implicates Rare Variants in Asthma Susceptibility
Common variation in over 100 genes has been implicated in the risk of developing asthma, but the contribution of rare variants to asthma susceptibility remains largely unexplored. We selected nine genes that showed the strongest signatures of weak purifying selection from among 53 candidate asthma-associated genes, and we sequenced the coding exons and flanking noncoding regions in 450 asthmatic cases and 515 nonasthmatic controls. We observed an overall excess of p values <0.05 (p = 0.02), and rare variants in four genes (AGT, DPP10, IKBKAP, and IL12RB1) contributed to asthma susceptibility among African Americans. Rare variants in IL12RB1 were also associated with asthma susceptibility among European Americans, despite the fact that the majority of rare variants in IL12RB1 were specific to either one of the populations. The combined evidence of association with rare noncoding variants in IL12RB1 remained significant (p = 3.7Â Ă 10â4) after correcting for multiple testing. Overall, the contribution of rare variants to asthma susceptibility was predominantly due to noncoding variants in sequences flanking the exons, although nonsynonymous rare variants in DPP10 and in IL12RB1 were associated with asthma in African Americans and European Americans, respectively. This study provides evidence that rare variants contribute to asthma susceptibility. Additional studies are required for testing whether prioritizing genes for resequencing on the basis of signatures of purifying selection is an efficient means of identifying novel rare variants that contribute to complex disease
An analysis of three curriculum approaches to teaching English in public-sector schools
This article explores three current, influential English language teaching (ELT) curriculum approaches to the teaching of English in public-sector schools at the primary and secondary level and how the theory of each approach translates into curriculum practice. These approaches are communicative language teaching (CLT), genre-based pedagogy, and content and language integrated learning (CLIL). For consistency across approaches, the theoretical underpinnings of each will be briefly described according to a matrix of curriculum factors including: ⢠the view of language and language acquisition underlying the approach ⢠how learners' needs are construed ⢠the nature of the content and materials ⢠the teacher's role ⢠the context ⢠how language is assessed This is followed by a discussion of research on how each approach is implemented in primary and secondary contexts, the extent to which the theory is put into practice and factors that influence its success in the classroom. Implications for the future of curriculum development in ELT will be discussed. These implications address the viability of CLT in primary and secondary schools, the role of knowledge about language in curriculum implementation, and teacher roles and identity
