Once Were Science Teachers

This paper explores the development of three pre-service science teacher educators\u27 understandings of some critical incidents in their development of science teachers that has impacted on the manner in which they teach about teaching in a teacher preparation program. The study draws on self-study methodology by situating their reflection on practice within a critical discourse whereby reframing has been important in learning through a reconsideration from particular critical incidents in their high school science teaching experiences. The authors argue that through critical reflection on practice, as illustrated in this paper, that the beginnings of the articulation and documentation of a knowledge base of teaching about teaching might be initiated. They therefore offer some of their emerging views on what that knowledge base might encompass through some assertions of practice that they believe impact on their teaching about teaching

Biometric surveillance in schools : cause for concern or case for curriculum?

This article critically examines the draft consultation paper issued by the Scottish Government to local authorities on the use of biometric technologies in schools in September 2008 (see http://www.scotland.gov.uk/Publications/2008/09/08135019/0). Coming at a time when a number of schools are considering using biometric systems to register and confirm the identity of pupils in a number of settings (cashless catering systems, automated registration of pupils' arrival in school and school library automation), this guidance is undoubtedly welcome. The present focus seems to be on using fingerprints, but as the guidance acknowledges, the debate in future may encompass iris prints, voice prints and facial recognition systems, which are already in use in non-educational settings. The article notes broader developments in school surveillance in Scotland and in the rest of the UK and argues that serious attention must be given to the educational considerations which arise. Schools must prepare pupils for life in the newly emergent 'surveillance society', not by uncritically habituating them to the surveillance systems installed in their schools, but by critically engaging them in thought about the way surveillance technologies work in the wider world, the various rationales given to them, and the implications - in terms of privacy, safety and inclusion - of being a 'surveilled subject'

Methodology: The Effects of Music Therapy on Individuals with Alzheimer’s Disease

Alzheimer’s Disease negatively impacts multiple aspects of one’s life including, but not limited to, physical, mental, emotional, and behavioral abilities, as well as the ability to complete activities of daily living (ADL’s). There are not many treatment options in order to improve the overall quality of life for Alzheimer’s patients, which in turn, improves the quality of life of their caregivers. Multiple research studies were compared through recruiting people aged 65 and above with mild to severe Alzheimer’s Disease to participate in different types of music intervention programs. Through analyzing the following research experiments, it was found that music therapy generally had a positive effect on the lives of Alzheimer’s patients and those who are caring for them. The results of these studies can be useful in treating Alzheimer’s patients through implementing music intervention programs as a form of therapy in order to improve their mental, physical, emotional, and behavioral abilities

Super-dosed Phytase Improves Rate and Efficiency of Gain in Nursery Pigs

The performance and growth of four hundred forty newly weaned nursery pigs were observed over a 35-day trial at the Iowa State University Swine Nutrition Farm. Pigs were allotted to one of four treatments: an NRC derived positive control [PC], a negative control with 10% lower SID lysine with relative lowering of all other essential amino acids and 1% reduced fat [NC], and two phytase levels: 0 vs 2,500 FTU Quantum Blue, with the 2,500 FTU being considered ‘super-dosed’. Pigs started with an average initial body weight of 6.27 ± 0.01 kg., and received feed and water ad libitum. For the overall experiment, both diet and phytase improved ADG and G:F. However, ADFI was unaffected, and there were no interactions. In conclusion, including phytase at super-dosed levels in the nursery pig diet improves growth performance, regardless of diet adequacy

(Correcting) misdiagnoses of asthma: A cost effectiveness analysis

This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.Background: The prevalence of physician-diagnosed-asthma has risen over the past three decades and misdiagnosis of asthma is potentially common. Objective: to determine whether a secondary-screening-program to establish a correct diagnosis of asthma in those who report a physician diagnosis of asthma is cost effective.Method: Randomly selected physician-diagnosed-asthmatic subjects from 8 Canadian cities were studied with an extensive diagnostic algorithm to rule-in, or rule-out, a correct diagnosis of asthma. Subjects in whom the diagnosis of asthma was excluded were followed up for 6-months and data on asthma medications and heath care utilization was obtained. Economic analysis was performed to estimate the incremental lifetime costs associated with secondary screening of previously diagnosed asthmatic subjects. Analysis was from the perspective of the Canadian healthcare system and is reported in Canadian dollars.Results: Of 540 randomly selected patients with physician diagnosed asthma 150 (28%; 95%CI 19-37%) did not have asthma when objectively studied. 71% of these misdiagnosed patients were on some asthma medications. Incorporating the incremental cost of secondary-screening for the diagnosis of asthma, we found that the average cost savings per 100 individuals screened was $35,141 (95$4,588-$69,278).Conclusion: Cost savings primarily resulted from lifetime costs of medication use averted in those who had been misdiagnosed.This work was funded by the Canadian Institute of Health Research, Canada and the University Of Ottawa Division Of Respiratory Medicine

Mental health consumer and caregiver perceptions of stigma in Australian community pharmacies

Background: The stigma of mental illness can be a barrier to effective medication management in the community pharmacy setting. This article explored mental health consumers’ or caregivers’ experiences of stigma in Australian community pharmacies. Materials: Semi-structured interviews and focus groups were conducted with a purposive sample of consumers or caregivers (n = 74). Interview transcripts were analysed using a general inductive approach. Discussion: Stigma presented a barrier to effective mental health management. Self-stigma impeded consumers’ community pharmacy engagement. Positive relationships with knowledgeable staff are fundamental to reducing stigma. Conclusions: Findings provide insight into the stigma of mental illness in community pharmacies

Media Reporting of Health Interventions: Signs of Improvement, but Major Problems Persist

Background: Studies have persistently shown deficiencies in medical reporting by the mainstream media. We have been monitoring the accuracy and comprehensiveness of medical news reporting in Australia since mid 2004. This analysis of more than 1200 stories in the Australian media compares different types of media outlets and examines reporting trends over time. Methods and Findings: Between March 2004 and June 2008 1230 news stories were rated on a national medical news monitoring web site, Media Doctor Australia. These covered a variety of health interventions ranging from drugs, diagnostic tests and surgery to dietary and complementary therapies. Each story was independently assessed by two reviewers using ten criteria. Scores were expressed as percentages of total assessable items deemed satisfactory according to a coding guide. Analysis of variance was used to compare mean scores and Fishers exact test to compare proportions. Trends over time were analysed using un-weighted linear regression analysis. Broadsheet newspapers had the highest average satisfactory scores: 58% (95% CI 56–60%), compared with tabloid newspapers and online news outlets, 48% (95% CI 44–52) and 48% (95% CI 46–50) respectively. The lowest scores were assigned to stories broadcast by human interest/current affairs television programmes (average score 33% (95% CI 28–38)). While there was a non- significant increase in average scores for all outlets, a significant improvement was seen in the online news media: a rise of 5.1% (95%CI 1.32, 8.97; P 0.009). Statistically significant improvements were seen in coverage of the potential harms of interventions, the availability of treatment or diagnostic options, and accurate quantification of benefits. Conclusion: Although the overall quality of medical reporting in the general media remains poor, this study showed modest improvements in some areas. However, the most striking finding was the continuing very poor coverage of health news by commercial current affairs television programs

Certifications of citizenship: the history, politics and materiality of identity documents in South Asian states and diasporas

Experiences in the post-partition Indian subcontinent refute the conventional expectation that the 'possession of citizenship enables the acquisition of documents certifying it' (Jayal, 2013, 71). Instead, identity papers of various types play a vital part in certifying and authenticating claims to citizenship. This is particularly important in a context where the history of state formation, continuous migration flows and the rise of right-wing majoritarian politics has created an uncertain situation for individuals deemed to be on the ‘margins’ of the state. The papers that constitute this special issue bring together a range of disciplinary perspectives in order to investigate the history, politics and materiality of identity documents, and to dismantle citizenship as an absolute and fixed notion, seeking instead to theorise the very mutable ‘hierarchies’ and ‘degrees’ of citizenship. Collectively they offer a valuable lens onto how migrants, refugees and socio-economically marginal individuals negotiate their relationship with the state, both within South Asia and in South Asian diaspora communities. This introduction examines the wider context of the complex intersections between state-issued identity documents and the nature of citizenship and draws out cross-cutting themes across the papers in this collection

Methicillin Resistance Alters the Biofilm Phenotype and Attenuates Virulence in Staphylococcus aureus Device-Associated Infections

Clinical isolates of Staphylococcus aureus can express biofilm phenotypes promoted by the major cell wall autolysin and the fibronectin-binding proteins or the icaADBC-encoded polysaccharide intercellular adhesin/poly-N-acetylglucosamine (PIA/PNAG). Biofilm production in methicillin-susceptible S. aureus (MSSA) strains is typically dependent on PIA/PNAG whereas methicillin-resistant isolates express an Atl/FnBP-mediated biofilm phenotype suggesting a relationship between susceptibility to β-lactam antibiotics and biofilm. By introducing the methicillin resistance gene mecA into the PNAG-producing laboratory strain 8325-4 we generated a heterogeneously resistant (HeR) strain, from which a homogeneous, high-level resistant (HoR) derivative was isolated following exposure to oxacillin. The HoR phenotype was associated with a R602H substitution in the DHHA1 domain of GdpP, a recently identified c-di-AMP phosphodiesterase with roles in resistance/tolerance to β-lactam antibiotics and cell envelope stress. Transcription of icaADBC and PNAG production were impaired in the 8325-4 HoR derivative, which instead produced a proteinaceous biofilm that was significantly inhibited by antibodies against the mecA-encoded penicillin binding protein 2a (PBP2a). Conversely excision of the SCCmec element in the MRSA strain BH1CC resulted in oxacillin susceptibility and reduced biofilm production, both of which were complemented by mecA alone. Transcriptional activity of the accessory gene regulator locus was also repressed in the 8325-4 HoR strain, which in turn was accompanied by reduced protease production and significantly reduced virulence in a mouse model of device infection. Thus, homogeneous methicillin resistance has the potential to affect agr- and icaADBC-mediated phenotypes, including altered biofilm expression and virulence, which together are consistent with the adaptation of healthcare-associated MRSA strains to the antibiotic-rich hospital environment in which they are frequently responsible for device-related infections in immuno-compromised patients
