Unexplored Areas of Teacher Collaboration: Evidence from a Bangladeshi Rural Primary school

This study investigated how teachers in a rural primary school in Bangladesh understood collaboration, how it was exercised in a daily routine context and the factors that influenced their collaborative activities in a school setting. Teachers’ collaboration in such a Low- and Middle-Income Country (LMIC) context is underexplored. Moreover, collaborative professional development is a policy imperative in this country, and it was assumed that findings of this study may inform teachers, policymakers and teacher educators when designing and implementing School-Based Teacher Development (SBTD) programmes. A Critical Realist (CR) philosophy was adopted which calls for an understanding of the deep social structure and human agency to understand a social event. It allowed an in-depth understanding of the social context of the school and the agency of the teachers. An ethnographic approach adopted in this study helped to obtain authentic data about teachers’ day-to-day collaborative practice in the school context. A range of data collection methods including the audio recording of staffroom conversations, participant observations and interviews was undertaken for two months. A thematic analysis of the data showed that teachers understood collaboration as a matter of their day-to-day activities, which are not restricted to formal professional works but also include a range of informal, professional, social and emotional activities. Teachers were involved in planned and unplanned collaboration with the majority of them being unplanned social conversations. Yet, the collaborative activities seemed to have little impact on teachers’ professional development. Teachers’ understanding of collaboration and the nature of their collaborative activities were very much shaped by the wider culture and organisational norms and regulations. This study concluded that teachers need to be supported to use the collaborative spaces for their professional development. Further research is needed to identify the way teachers can be supported to utilise their collaboration

English Proficiency Assessments of Primary and Secondary Students Participating in English in Action: Third Cohort (2014) Large-Scale Quantitative Study

The purpose of the study was to assess the student learning outcomes of English in Action’s (EIA’s) school-based teacher development programme, in terms of improved English language competence (ELC), against recognised international frameworks (specifically, the Graded Examinations in Spoken English [GESE)]; Trinity College London 2013), which map onto the Common European Framework of Reference for Languages (CEFR). Measurably improved student learning outcomes are the ultimate test of success of a teacher development programme. English Proficiency Assessments 2014 is a repeat of the study on the pilot EIA programme (Cohort 14) (EIA 2012), but focusing only on student ELC. The teachers and hence the students of Cohort 3 are substantially greater in number than in the pilot phase (347,000 primary students and almost 1.7 million secondary students compared with around 700 teachers, 35,000 primary students and over 83,000 secondary students in 2011). To enable this increase in scale, the programme has been delivered through a more decentralised model, with much less direct contact with English language teaching (ELT) experts, a greater embedding of expertise within teacher development materials (especially video), and a greater dependence upon localised peer support. This report addresses the following research question: To what extent do the students of Cohort 3 show improved post-intervention EL proficiencies, in speaking and listening, compared with the Cohort 1 2010 preintervention baseline

Domestic accidents in a rural community of Bangladesh: A cross-sectional study on their incidence and characteristics.

In a developing country like Bangladesh knowledge about domestic accidents is sparse. But accident is one of the major causes of morbidity and mortality in both developed and developing countries. [1] The relationship between domestic accidents and human health is direct and associated with a chain of socio-economic consequences. In this paper we try to bring out the patterns of domestic accidents and their characteristics in a rural community of Bangladesh. A questionnaire survey was conducted on 297 households of Shitpara village under Bormi union of Shreepur Upazilla constituting 1171 family members to determine the prevalence and characteristics of household accidents. The collected data were then analyzed by SPSS 16. (Statistical package for social science)A total of 171 domestic accidents had occurred during one year period with a prevalence of 146.02/1000 population. Majority of the victims are male (52.6%). Commonest household accident was fall (50.9%) followed by Cut injury (22.2%) and Burn (11.7%).Health education program aimed at prevention and first aid treatment of domestic accidents and proper use of personal protective measures are recommended.

Double burden of malnutrition in children aged 24 to 59 months by socioeconomic status in five South Asian countries: evidence from demographic and health surveys

Objectives We aimed to investigate the socioeconomic inequalities in the burden of underweight and overweight among children in South Asia. We also examined other factors that were associated with these outcomes independently of household’s socioeconomic status. Design Nationally-representative surveys. Settings Demographic and Health Surveys from Bangladesh, India, Pakistan, Maldives and Nepal, which were conducted between 2009 and 2016. Participants Children aged 24 to 59 months with valid measurement for height and weight (n=146 996). Primary exposure and outcome measures Primary exposures were household’s wealth index and level of education. Underweight and overweight were defined according to the WHO and International Obesity Task Force definitions, respectively. Results Underweight prevalence was 37% in Bangladesh, 38% in India, 19% in Maldives, 29% in Nepal and 28% in Pakistan. Bangladesh, India and Nepal had similar overweight prevalence (between 2% and 4%) whereas Pakistan (7%) and Maldives (9%) had higher prevalence. Households with higher wealth index or education had lower odds of having underweight children. Adjusted ORs of underweight for richest versus poorest households were 0.4 (95% CI: 0.3 to 0.5), 0.5 (95% CI: 0.5 to 0.6), 0.5 (95% CI: 0.2 to 1.4), 0.5 (95% CI: 0.3 to 0.8) and 0.7 (95% CI: 0.5 to 1.1) for Bangladesh, India, Maldives, Nepal and Pakistan, respectively. Compared with poorest households, richest households were more likely to have overweight children in all countries except Pakistan, but such associations were not significant after adjustment for other factors. There were higher odds of having overweight children in households with higher education in Bangladesh (OR 2.1 (95% CI: 1.3 to 3.5)), India (OR 1.2 (95% CI: 1.2 to 1.3)) and Pakistan (OR 1.8 (95% CI: 1.1 to 2.9)) when compared with households with no education. Maternal nutritional status was consistently associated with children’s nutritional outcomes after adjustments for socioeconomic status. Conclusions Our study provides evidence for socioeconomic inequalities for childhood underweight and overweight in South Asian countries, although the directions of associations for underweight and overweight might be different

Do the dietary and lifestyle practices make the private medical students overweight: A cross-sectional study in Bangladesh?

Introduction: Increased mechanization and change in the food patterns are leading to physical inactivity and more energy intake globally. That’s why, obesity and overweight are no longer confined to the industrialized countries; it has spread to the developing countries as well. In Bangladesh also over-nutrition is increasing alarmingly. As the future doctors, medical students should adopt healthy dietary and lifestyle practices from the very beginning of their youth for contributing more effectively and efficiently to the country’s healthcare. Objectives: The study assessed the prevalence of overweight, the dietary and lifestyle determinants of overweight among the students of an urban private medical college of Bangladesh. Methodology: A cross-sectional study was conducted in Ibrahim Medical College, a private medical college in Dhaka city. Data was collected through self-administered questionnaires and anthropometric measurements. Data Analysis was done by SPSS version 17.0 Results: The Prevalence of overweight among the medical students was found to be 27.16% (Male 39% and female 22%) . 58% of the respondents had positive family history of overweight/obesity and around 70% of them had positive family history of Type 2 Diabetes and Hypertension. The dietary factors associated with overweight were increased frequency of eating at fast food shops and drinking sweetened tea or coffee. Among the lifestyle factors, liberal family rules regarding food, prolonged gap (?120 minutes) between waking up and having breakfast, taking meal while watching TV or using computer and inadequate sleep (<7 hours of sleep) were found to be associated with being overweight. Binary logistic regression concludes that positive family history of overweight/obesity; inadequate sleep and a prolonged gap between waking up and having breakfast were significantly contributing to be overweight. Conclusion: The prevalence of overweight among the urban private medical college students was found to be higher than the available data of overweight in Bangladesh. Along with dietary habits, lifestyle practices are also becoming more and more important determinants of being overweight. The medical students should be counseled and advised to bring positive attitude towards healthy lifestyle and dietary practices.

Attitude towards diabetes and social and family support among type 2 diabetes patients attending a tertiary-care hospital in Bangladesh: a cross-sectional study

Background: Bangladesh has been suffering from an epidemiological transition from infectious and maternal diseases to non-communicable lifestyle-related diseases like diabetes, cardiovascular diseases, cancers etc. The burden of diabetes has been increasing rapidly due to high incidence as well as poor glycemic control leading to various macro and micro-vascular complications. In this study, we aim to assess the attitude towards diabetes and social and family support among the Bangladeshi type 2 diabetic mellitus (T2DM) patients. Methods: This was a cross-sectional study among 144 patients with T2DM at the medicine outpatient department of Dhaka Medical College Hospital (DMCH) in Dhaka, Bangladesh between 1 July and 31 July 2014. Data collection was done by interviewing patients using structured questionnaire. Understanding diabetes, education/advice received, attitude towards diabetes, family and friend support were measured by validated scales adapted from diabetes care profile. Results: This study includes a total of 144 patients (101 males and 43 females) with type 2 diabetes aged between 20 and 84 years. 87 % of the patients had inadequate blood glucose control (fasting blood sugar >7.2 mmol/L or >130 mg/dl). Statistically significant differences were observed in the mean scores of various attitude scales (i.e. positive, negative, care ability and self-care adherence scale) among patients with adequate and inadequate blood glucose control (p < 0.05). Statistically significant positive correlations were found between these three categories of social and family support. Self-satisfaction with diabetic care was significantly associated with adequate blood glucose control (p = 0.05). Conclusions: Positive attitude towards diabetes management and support from friends and family were associated with adequate diabetes management. Appropriate public health interventions should be designed to educate and motivate the family members to offer greater support to the diabetes patients

Adoption Determinants of Exotic Rice Cultivars in Bangladesh

Agrarian Bangladesh relies heavily on rice. Since independence, many varieties have been released and targeted to increase productivity, farmers' income, and food security. However, few gained widespread adoption. Moreover, farmers in the border regions are adopting exotic cultivars, and it's gradually spreading throughout the country. But, the reasons for adopting exotic rice cultivars are still unexplored. Using field data from 1,260 farm households and 42 focus group discussions, this study analyzes farmers' preferences for domestic and exotic rice varieties and identifies the factors of adoption linked to design national breeding programs and farmers' welfare. Findings show, exotic varieties (69%) monopolized the area coverage in the dry season, whereas in the wet season, domestic varieties (58%) dominated. Farmers select exotic varieties for their better yield and price, low production costs, high grain quality, resistance to pests and diseases, and ability to withstand stresses. Risk analysis shows domestic varieties adoption is riskier with lower returns. The empirical findings indicate that household characteristics, access to institutions and infrastructure, varietal characteristics, and weather condition, all play a significant role in adoption decisions. National breeding should focus on developing rice varieties in response to market demands and farmer preferences toward sustainable food security in Bangladesh

Hydrogeochemical quality and suitability studies of groundwater in northern Bangladesh

Agriculture, rapid urbanization and geochemical processes have direct or indirect effects on the chemical composition of groundwater and aquifer geochemistry. Hydro-chemical investigations, which are significant for assessment of water quality, were carried out to study the sources of dissolved ions in groundwater of Dinajpur district, northern Bangladesh. The groundwater samplish were analyzed for physico-chemical properties like pH, electrical conductance, hardness, alkalinity, total dissolved solids and Ca2+, Mg2+, Na+, K+, C032', HC03", SO,2 and CI" ions, respectively. Based on the analyses, certain parameters like sodium adsorption ratio, soluble sodium percentage, potential salinity, residual sodium carbonate, Kelly's ratio, permeability index and Gibbs ratio were also calculated. The results showed that the groundwater of study area was fresh, slightly acidic (pH 5.3-6.4) and low in TDS (35-275 mg I"1). Ground water of the study area was found suitable for irrigation, drinking and domestic purposes, since most of the parameters analyzed were within the WHO recommended values for drinking water. High concentration of N03" and CI' was reported in areas with extensive agriculture and rapid urbanization. Ion-exchange, weathering, oxidation and dissolution of minerals were major geochemical processes governing the groundwater evolution in study area. Gibb's diagram showed that all the samples fell in the rock dominance field. Based on evaluation, it is clear that groundwater quality of the study area was suitable for both domestic and irrigation purposes

Dynamic interventions to control COVID-19 pandemic: a multivariate prediction modelling study comparing 16 worldwide countries

Daniel Reidpath - ORCID: 0000-0002-8796-0420 https://orcid.org/0000-0002-8796-0420To date, non-pharmacological interventions (NPI) have been the mainstay for controlling the coronavirus disease-2019 (COVID-19) pandemic. While NPIs are effective in preventing health systems overload, these long-term measures are likely to have significant adverse economic consequences. Therefore, many countries are currently considering to lift the NPIs—increasing the likelihood of disease resurgence. In this regard, dynamic NPIs, with intervals of relaxed social distancing, may provide a more suitable alternative. However, the ideal frequency and duration of intermittent NPIs, and the ideal “break” when interventions can be temporarily relaxed, remain uncertain, especially in resource-poor settings. We employed a multivariate prediction model, based on up-to-date transmission and clinical parameters, to simulate outbreak trajectories in 16 countries, from diverse regions and economic categories. In each country, we then modelled the impacts on intensive care unit (ICU) admissions and deaths over an 18-month period for following scenarios: (1) no intervention, (2) consecutive cycles of mitigation measures followed by a relaxation period, and (3) consecutive cycles of suppression measures followed by a relaxation period. We defined these dynamic interventions based on reduction of the mean reproduction number during each cycle, assuming a basic reproduction number (R0) of 2.2 for no intervention, and subsequent effective reproduction numbers (R) of 0.8 and 0.5 for illustrative dynamic mitigation and suppression interventions, respectively. We found that dynamic cycles of 50-day mitigation followed by a 30-day relaxation reduced transmission, however, were unsuccessful in lowering ICU hospitalizations below manageable limits. By contrast, dynamic cycles of 50-day suppression followed by a 30-day relaxation kept the ICU demands below the national capacities. Additionally, we estimated that a significant number of new infections and deaths, especially in resource-poor countries, would be averted if these dynamic suppression measures were kept in place over an 18-month period. This multi-country analysis demonstrates that intermittent reductions of R below 1 through a potential combination of suppression interventions and relaxation can be an effective strategy for COVID-19 pandemic control. Such a “schedule” of social distancing might be particularly relevant to low-income countries, where a single, prolonged suppression intervention is unsustainable. Efficient implementation of dynamic suppression interventions, therefore, confers a pragmatic option to: (1) prevent critical care overload and deaths, (2) gain time to develop preventive and clinical measures, and (3) reduce economic hardship globally.https://doi.org/10.1007/s10654-020-00649-w35pubpub
