Increasingly and more interestingly, the landscape is being shaped by the narratives and experiences of the learners themselves (Creanor et al., 2006, Conole et al., 2006) and the use of Web 2.0 technologies. However, as Laurillard (2007, p.xv) reminds us we still, ‘tend to use technology to support traditional modes of teaching’ and ‘we scarcely have the infrastructure, the training, the habits or the access to the new technology, to be optimising its use just yet’ (p.48). Web 2.0 spaces, literacies and practices offer the possibility for new models of education (Mayes & de Freitas, 2007, p.13) which support iterative and integrative learning but as educators and higher educational establishments are we prepared and ready to re-think our pedagogies and re-do (Beetham & Sharpe 2007, p.3) our practices? This concise paper will reflect upon how the use of new learning landscapes such as eportfolios might offer us the opportunity to reflect upon the implications of letting in the e-learning eportfolio Trojan mouse (Sharpe & Oliver, 2007, p.49)
CES-D four-factor structure is confirmed, but not invariant, in a large cohort of African American women
No full textThis study examined the factor structure of the Centers for Epidemiologic Studies Depression Scale (CES-D) in a sample of 40,403 African American women participating in the Black Women\u27s Health Study (BWHS). To examine within group differences in the structural characteristics of the CES-D, women were stratified by age (\u3c 60 vs. ≥ 60 years). Confirmatory factor analysis indicated that a four-factor solution was a good fit for the data in both groups. The four factors extracted (depressed, somatic, positive, and interpersonal) matched findings from previous studies in other populations. Although item loadings were identical for 19 of 20 items, when equality restrictions were placed on factor loadings, the factors were not shown to be equivalent across groups. The only observed difference in item loadings was that the item people disliked me loaded higher on the interpersonal factor for younger women than older women. The variance/covariance matrix differed between groups. The correlations between the depressed and somatic factors were identical for the two age groups. However, correlations among the other factors were weaker among older women. We conclude that four-factor structure of the CES-D is supported for African American women, but the relationships among the factors vary with age. © 2006 Elsevier Ireland Ltd. All rights reserved

Association between cigarette smoking and colorectal cancer in the Women\u27s Health Initiative
No full textThe evidence linking cigarette smoking to the risk of colorectal cancer is inconsistent. We investigated the associations between active and passive smoking and colorectal cancer among 146877 Women\u27s Health Initiative participants. Women reported detailed smoking histories at enrollment. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated for the association between smoking and overall and site-specific risk of colorectal cancer. Invasive colorectal cancer was diagnosed in 1242 women over an average of 7.8 years (range = 0.003-11.2 years) of follow-up. In adjusted analyses, statistically significant positive associations were observed between most measures of cigarette smoking and risk of invasive colorectal cancer. Site-specific analyses indicated that current smokers had a statistically significantly increased risk of rectal cancer (HR = 1.95, 95% CI = 1.10 to 3.47) but not colon cancer (HR = 1.03, 95% CI = 0.77 to 1.38), compared with never smokers. Passive smoke exposure was not associated with colorectal cancer in adjusted analyses. Thus, active exposure to cigarette smoking appears to be a risk factor for rectal cancer. © The Author 2007.

A population approach to characterise amisulpride pharmacokinetics in older people and Alzheimer's disease
No full textIntroduction Current prescribing guidelines for the antipsychotic amisulpride are based largely on pharmacokinetic (PK) studies in young adults, and there is a relative absence of data on older patients, who are at greatest risk of developing adverse events.
Methods This study aimed to develop a population PK model for amisulpride specifically in older people, by combining data from a richly sampled phase 1, single (50 mg) dose study in healthy older people (n = 20, 65–79 years), with a clinical dataset obtained during off label, low-dose (25–75 mg daily) amisulpride prescribing in older people with Alzheimer’s disease (AD) (n = 25, 69–92 years), as part of an observational study.
Results After introducing a scaling factor based on body weight, age accounted for 20 % of the inter-individual variability in drug clearance (CL), resulting in a 54 % difference in CL between those aged 65 and those aged 85 years, and higher blood concentrations in older patients.
Discussion These findings argue for the consideration of age and weight-based dose stratification to optimise amisulpride prescribing in older people, particularly in those aged 85 years and above

On another day he speaks in front of the New England Fishery Management Council protesting limits to days at sea and saying he\u27ll have to be dragged kicking and screaming from his boat
"What does a scanner see?": Philip K. Dick's and Richard Linllater's take on identity and identity crisis
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Letras/Inglês e Literatura Correspondente, Florianópolis, 2012.Abstract : This research presents a comparative analysis between Philip K. Dick s 1977 novel A Scanner Darkly and Richard Linklater s 2006 homonymous film adaptation of it. The focus of this analysis is the theme of postmodern identity, having as a theoretical framework the issues about identity and postmodernism problematized by theorists such a Fredric Jameson and Stuart Hall. This analysis shows how the issue of postmodern identity is ubiquitous both in Dick s novel and in Linklater s film. In order to analyze the issue of adaptation, the ideas of scholars such as Dudley Andrew and Robert Stam, as well as film theorist André Bazin were used. The differences between a novel and a film that narrate the same story are unavoidable. However, what is possible to see in the case of A Scanner Darkly is that the treatment and the emphasis given to the issue of postmodern identity in both works is equivalent. In order to do so, the film takes advantage of the specificities of its medium to represent elements that, due to each medium s nature, cannot be transposed into a film.Esta pesquisa apresenta uma análise comparativa entre o romance de Philip K. Dick A Scanner Darkly (O Homem Duplo  1977) e a adaptação cinematográfica homônima feita por Richard Liklater em 2006. O foco desta análise é o tema da identidade pós-moderna, usando como base teórica as questões sobre identidade e pós-modernidade problematizadas por teóricos como Fredric Jameson e Stuart Hall. A partir desta análise, é possivel observar como o tema da identidade pósmoderna é ubíquo e ambas as obras. Para analisar as questões relacionadas a adaptação, foram utilizadas as ideias de acadêmicos como Dudley Andrew e Robert Stam, assim como do teórico André Bazin. As diferenças entre um romance e um filme que narram a mesma história são inevitáveis. Porém, o que é possível ver no caso de A Scanner Darkly é que o tratamento e a ênfase dados ao tema da identidade pós-moderna em ambas as obras é equivalente. Para tanto, o filme utiliza as especificidades do seu meio para representar possíveis elementos que, por conta da natureza de cada meio, não podem ser transpostos para o cinema
Leisure time physical activity in relation to depressive symptoms in the Black Women\u27s Health Study
No full textBackground: A growing body of evidence suggests that physical activity might reduce the risk of depressive symptoms, but there are limited data on Black women. Purpose: The objective was to evaluate the association between leisure time physical activity and depressive symptoms in U.S. Black women. Methods: Participants included 35,224 women ages 21 to 69 from the Black Women\u27s Health Study, a follow-up study of African American women in which data are collected biennially by mail questionnaire. Women answered questions on past and current exercise levels at baseline (1995) and follow-up (1997). The Center for Epidemiologic Studies Depression Scale (CES-D) was used to measure depressive symptoms in 1999. Women who reported a diagnosis of depression before 1999 were excluded. We used multivariate logistic regression models to compute odds ratios (ORs) and 95% confidence intervals (CIs) for physical activity in relation to depressive symptoms (CES-D score ≥ 16) with control for potential confounders. Results: Adult vigorous physical activity was inversely associated with depressive symptoms. Women who reported vigorous exercise both in high school (≥ 5 hr per week) and adulthood (≥ 2 hr per week) had the lowest odds of depressive symptoms (OR = 0.76, 95% CI = 0.71-0.82) relative to never active women; the OR was 0.90 for women who were active in high school but not adulthood (95% CI = 0.85-0.96) and 0.83 for women who were inactive in high school but became active in adulthood (95% CI = 0.77-0.91). Although walking for exercise was not associated with risk of depressive symptoms overall, there was evidence of a weak inverse relation among obese women (Body Mass Index ≥ 30). Conclusions: Leisure time vigorous physical activity was associated with a reduced odds of depressive symptoms in U.S. Black women. © 2006 by The Society of Behavioral Medicine
RedFeather- resource exhibition and discovery: a lightweight micro-repository for resource sharing
No full textOpen Educational Resources (OERs) depend on being hosted in repositories so that they can be effectively viewed, managed, searched and indexed online. Content – especially multimedia content – that is not hosted in this way has no metadata and is effectively dark to the wider community. Similarly content that is not described properly, and with appropriate licenses, is of limited use. This is a challenge for small-scale contributors, such as individuals and small projects, as the overhead of setting up and administrating a content repository can be prohibitive.In this paper we propose RedFeather, a micro-repository, as a solution to this problem. RedFeather is a simple and straightforward server-side tool that requires zero to little configuration, but that provides the core functionality of a fully-fledged OER repository, including: resource pages with inline preview, a resource manager with streamlined workflow, and views of the resource in OER critical formats (including RDF, JSON, and RSS). RedFeather is fully customizable, with a flexible plugin architecture and configurable templates, but also works without any customization as a single php script file uploaded to a web server. The goal of a micro-repository like RedFeather is both to enable small-scale contributors to easily join the OER community, and to act as a intermediate step for larger contributors beginning a collection, or requiring a temporary home for their resources while a more substantial repository is developed. Our hope is that by lowering the barriers to participation, RedFeather can help the OER community to take advantage of the long tail of small to medium sized content creators
