Teachers’ views on effective classroom management: a mixed-methods investigation in Western Australian high schools

© 2020, The Author(s). Teachers’ views about teaching, learning and school experiences are important considerations in education. As the central participants in classroom interactions, students and teachers naturally have strong views about what it takes to manage learning and surrounding behaviours effectively. With this in mind and because we believe that ignoring the thinking of either of these stakeholders would be to the detriment of teaching and teacher education, we focused on hearing and understanding teachers’ voices about teaching, learning and classroom management. Our aim was to further clarify teachers’ perspectives on how educators create quality learning environments as well as gathering their views of various disciplinary interventions, their perceptions of challenging students and their sense of efficacy for classroom management in order to inform both policy and practice in teacher education. A survey was conducted with 50 secondary school teachers to capture their views on their classroom experiences. Follow up interviews with teachers identified by students as effective in their classroom management provided consistent reports that effective classroom managers build positive relationships with their students, manage their classrooms by establishing clear boundaries and high expectations, and engage students in their learning

Classroom Management and National Professional Standards for Teachers: A Review of the Literature on Theory and Practice

This article reviews the conceptual and empirical research on classroom management to ascertain the extent to which there is consistency between the “advice” found in the research literature and the professional standards for teachers and initial teacher education, in regards to knowledge and perspectives about effective classroom management. Focusing on the evolution of beliefs, knowledge and perspectives about classroom management the article will clarify effective classroom management and place this within the frameworks on effective teaching, in particular the AITSL standards, and consequently consider some implications for best practice

Interaction between interleukin-10 (IL-10) polymorphisms and dietary fibre in relation to risk of colorectal cancer in a Danish case-cohort study

<p>Abstract</p> <p>Background</p> <p>More than 50% of the colorectal cancer (CRC) etiology has been attributed to diet. Established or suspected dietary factors modifying risk of CRC are red meat, cereals, fish, and fibre. Diet and lifestyle may be linked to cancer through inflammation. Interleukin-10 (IL-10) is an anti-inflammatory cytokine. We wanted to test if dietary factors and <it>IL10</it> polymorphisms interact in relation to colorectal carcinogenesis.</p> <p>Methods</p> <p>The functional <it>IL10</it> polymorphism C-592A (rs1800872) and the marker rs3024505 were assessed in relation to diet and lifestyle in a nested case-cohort study of 378 CRC cases and 775 randomly selected participants from a prospective study of 57,053 persons. Genotyping data on the <it>IL10</it> polymorphism C-592A, smoking and non-steroidal anti-inflammatory drugs (NSAID) was retrieved from Vogel et al. (Mutat Res, 2007; 624:88). Incidence rate ratios (IRR) and 95% Confidence Interval (95% CI) were calculated.</p> <p>Results</p> <p>No associations were found between the <it>IL10</it> rs3024505 polymorphism and risk of CRC. There was interaction between rs3024505 and dietary fibre (P-value for interaction = 0.01). <it>IL10</it> rs3024505 homozygous wildtype carriers were at 27% reduced risk of CRC per 10 g fibre per day (95% CI: 0.60-0.88) whereas variant carriers had no risk reduction by fibre intake. Also, interaction between <it>IL10</it> C-592A and intake of fibre was found (P-value for interaction = 0.02). Among those eating <17.0 grams of fibre per day, carriers of an C-592A variant allele had a statistically significantly higher risk of colorectal cancer compared to homozygous wildtypes. No significant differences in colorectal cancer risk were observed between the reference group (CC and <17.0 g/day) and carriers of one C-592A variant allele eating 17.0 or more grams of dietary fibre per day. This suggests that the increased risk due to carrying the variant allele can be overcome by higher fibre intake. No interactions between <it>IL10</it> polymorphisms and dietary meat, cereal, or fish intake, or between <it>IL10</it> rs3024505 and smoking or NSAID use were found.</p> <p>Conclusions</p> <p>In this northern Caucasian cohort we found interaction between <it>IL10</it> and dietary fibre in CRC carcinogenesis. High intake of fibre seems to protect against CRC among individuals with <it>IL10</it> related genetic susceptibility to CRC. This finding should be evaluated in other prospective and population-based cohorts with different ethnic groups.</p

Modelling the optimal sequence of biologic therapies in plaque psoriasis in Spain

Aim: The purpose of this manuscript was to illustrate the impact of the place in the treatment sequence on the cost and cost-effectiveness of different biologics for patients with moderate-to-severe plaque psoriasis. Materials and methods: We developed a treatment sequence model and focused on seven different biological treatment options and 840 combinations of treatment sequences. The model converted cost of treatment to a cost per responder by dividing treatment cost by expected number of patients achieving PASI100 after 52 weeks of treatment. We used Spanish ex-factory price levels, dosing recommendations and real-world data on drug survival to calculate the treatment costs. Results: The most cost-effective treatment sequence was brodalumab-risankizumab-guselkumab-ixekizumab, with a cost per responder of €139,281 during the first five years of treatment. In comparison, if brodalumab was not recommended as first-line therapy, total costs would increase by 7.4% to €149,616. If brodalumab was not recommended as any of the first four lines of treatment, total costs would increase by 13.1% to €157,527 relative to the most cost-effective treatment sequence. Conclusions: A sequential therapy model may improve efficiency in the treatment of psoriasis. According to our results, brodalumab as the first-line therapy in Spain leads to the most cost-effective treatment sequence

Meat, eggs, dairy products, and risk of breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort

Background: A Western diet is associated with breast cancer risk. Objective: We investigated the relation of meat, egg, and dairy product consumption with breast cancer risk by using data from the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: Between 1992 and 2003, information on diet was collected from 319,826 women. Disease hazard ratios were estimated with multivariate Cox proportional hazard models. Results: Breast cancer cases (n = 7119) were observed during 8.8 y (median) of follow-up. No consistent association was found between breast cancer risk and the consumption of any of the food groups under study, when analyzed by both categorical and continuous exposure variable models. High processed meat consumption was associated with a modest increase in breast cancer risk in the categorical model (hazard ratio: 1.10; 95% CI: 1.00, 1.20; highest compared with lowest quintile: P for trend = 0.07). Subgroup analyses suggested an association with butter consumption, limited to premenopausal women (hazard ratio: 1.28; 95% CI: 1.06, 1.53; highest compared with lowest quintile: P for trend = 0.21). Between-country heterogeneity was found for red meat (Q statistic = 18.03; P = 0.05) and was significantly explained (P = 0.023) by the proportion of meat cooked at high temperature. Conclusions: We have not consistently identified intakes of meat, eggs, or dairy products as risk factors for breast cancer. Future studies should investigate the possible role of high-temperature cooking in the relation of red meat intake with breast cancer risk. Am J Clin Nutr 2009;90:602-12

Meat consumption and mortality -results from the European Prospective Investigation into Cancer and Nutrition

Abstract Background: Recently, some US cohorts have shown a moderate association between red and processed meat consumption and mortality supporting the results of previous studies among vegetarians. The aim of this study was to examine the association of red meat, processed meat, and poultry consumption with the risk of early death in the European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: Included in the analysis were 448,568 men and women without prevalent cancer, stroke, or myocardial infarction, and with complete information on diet, smoking, physical activity and body mass index, who were between 35 and 69 years old at baseline. Cox proportional hazards regression was used to examine the association of meat consumption with all-cause and cause-specific mortality. Results: As of June 2009, 26,344 deaths were observed. After multivariate adjustment, a high consumption of red meat was related to higher all-cause mortality (hazard ratio (HR) = 1.14, 95% confidence interval (CI) 1.01 to 1.28, 160+ versus 10 to 19.9 g/day), and the association was stronger for processed meat (HR = 1.44, 95% CI 1.24 to 1.66, 160+ versus 10 to 19.9 g/day). After correction for measurement error, higher all-cause mortality remained significant only for processed meat (HR = 1.18, 95% CI 1.11 to 1.25, per 50 g/d). We estimated that 3.3% (95% CI 1.5% to 5.0%) of deaths could be prevented if all participants had a processed meat consumption of less than 20 g/day. Significant associations with processed meat intake were observed for cardiovascular diseases, cancer, and &apos;other causes of death&apos;. The consumption of poultry was not related to all-cause mortality. Conclusions: The results of our analysis support a moderate positive association between processed meat consumption and mortality, in particular due to cardiovascular diseases, but also to cancer
