Solar energy has a great potential to give cheap and abundant energy to rural areas of the world, but is the technology ready to be implemented today? This stydy looked at the possibilities to introduce more renewable energy into the local hand-made paper production in Bangladesh. Specifically the potential of solar heated vacuum tubes filled with water as a heat carrier. This type of solar thermal collectors are cheap to produce, relatively efficient at converting both direct and diffuse solar energy into usable energy, and have a very simple construction that do not require a lot of training to handle. The study showed that the collector could convert about 70 % of the energy from the sun into usable energy in the form of hot water circulated in the system. On average in Bangladesh the 5 m2 collector used is expected to have an output of about 25.6 MJ per day (yearly average) and about 4.8 MJ was needed to evaporate 1 kg of water from the drying papers (including the system losses). This can be compared with the old system that used about 8 MJ per kg water evaporated. Finally the study includes a step by step guide into how to build a system like this by locally available material. The only parts that were imported were some measurement equipment and parts of the collector that was not yet available through local distributors. The pump was also not produced in Bangladesh, but a similar pump could be bought by local companies that import this type of equipment.

Efforts to commercialize water supply and sanitation in Dhaka, Bangladesh, have been pushed vigorously by internal and external proponents of neo-liberalism. The thesis takes a critical look at these developments and analyzes the role of multinational finance institutions in this process. In particular, it looks into the role of these finance institutions in funding reform projects to corporatize Dhaka Water Supply and Sewerage Authority (WASA), examining the impacts on end users, especially marginalized sections of society. The thesis describes how, in the process of corporatization, Dhaka WASA is and will continue to be more assertive in its commercial orientation than it was previously. The paper also studies a highly touted ‘successful’ co-operative model for revenue management called Program for Performance Improvement (PPI), seen by some as an alternative to privatization. I argue that the model in fact emerged as a consequence of the commercialization efforts of neoliberal reforms and that the revenue management model has created an isolated business unit with a reclusive management that undermines the egalitarian objectives of the water utility as a public service entity. / Thesis (Master, Environmental Studies) -- Queen's University, 2009-01-06 12:06:45.901

My dissertation discusses refugee rights and post-repatriation integration in South Asia in the context of debates over "citizenship." Postcolonial state-formation processes in South Asia have profoundly shaped questions of belonging and membership. As a result, official citizenship has become an important marker of group inclusion and exclusion in South Asian states. Using the literature on citizenship, I discuss the "belonging" claims of non-citizens (refugees) and argue that in practice this "belonging" extends beyond the state-centric "citizenship" view of membership. In doing so, I address two sets of interrelated questions: what factors determine whether or not refugees will be repatriated in South Asia, and why do some repatriated groups re-integrate more successfully than others in "post-peace" South Asian states? I answer these questions through a study of refugees from Sri Lanka and Bangladesh who sought asylum in India and were later repatriated to their countries of origin. The politics of postcolonial state-formation and subsequent discriminatory policies on language in Sri Lanka and non-recognition of the Jumma people in Bangladesh encouraged many citizens to flee to India as refugees. I argue, first, that India's state-centric politics of non-recognition of the two refugee groups contributed to their later repatriation. In the absence of rights and status in exile, refugees turned to "home" as a place to belong. I then analyze the post-repatriation variations in accommodation in Sri Lanka and Bangladesh as most refugees attempted to reclaim the lost identity and "citizenship" at "home" through the process of repatriation. However these countries pursued strategies of limited accommodation, which led to the minimal or partial re-integration of the two returnee-refugee groups.

This investigation reports on a study that explores the views of students, teachers and parents about the Communicative Language Teaching (CLT) approach in learning English as a second language in Bangladesh. This study focuses on the improvement of English language outcomes in Bangladesh. Though compulsory for fifteen years of schooling, public examination results indicate that students perform poorly in English. This research is conducted at the secondary schools in Bangladesh where English is compulsory because of its global nature as the second or foreign language. Mainstream students learning English using the Communicative Language Teaching (CLT) approach are facing many challenges. The study employs a mixed methods approach which includes qualitative interviews, semi-structured focus group interviews and observations; and quantitative data involved achievement tests to find gaps between oral and written attainment, in order to determine the effectiveness of CLT developing language skills to communicate in and outside the classrooms. ESL learners in Bangladesh have been using CLT for nearly two decades, but the attainments are not satisfactory particularly in oral language (listening and speaking) compared to written language (reading and writing). Four schools (two high and two low achievement) were selected from two divisional cities according to the public examination results. Five students, all English subject teachers and five parents from each school were invited randomly to participate. Findings indicated a confirmation of the gap between oral and written language achievements and highlighted that CLT is not working effectively to develop communicative competence to the learners. The participants identified several factors causing this. Among these were large class sizes (number of students), an extensive curriculum, insufficient class time (duration), an inappropriate examination system, excessive teacher workload, lack of parent awareness of CLT, and negative relationships between home and school. All of these factors impact on the effectiveness of CLT in Bangladesh. All participants agreed that CLT as an approach is better than other approaches used in Bangladesh to develop English language learning, but the varied interpretation and implementation (practice) makes it less effective. Therefore, they suggested some issues for local and national level policy makers that could enhance the CLT practice in Bangladesh.

Purpose – The purpose of this work is to examine the actual CSR situation in low wage countries of the textile industry and to identify obstacles and suggestions for improvements of the working conditions. In order to achieve that approach, different sources and various articles, magazines, books and related websites are being researched to get a wide range of information and to avoid a partial reflection. Furthermore an exemplary discussion of the CSR activities of two leading fashion retailers, Bestseller and H&M will be implemented by having a look on their company homepages as well as their current and previous annual reports and stated CSR activities. In addition, interviews with international operating NGO’s, fair trade unions and human right foundations will be conducted to receive widely independent information, deeper insights and critics concerning CSR and Human Development in the textile business. These interviews are of crucial importance for this work, since they provide widely independent assessments of the actual state of CSR implementation within the industry. By considering all the different information, this work provides ultimately indications for grievances and proposals for improvements in Human Development. Methodology – Using a qualitative research strategy, this work begins with a definition of CSR and Human Development, which provides a necessary background knowledge to approach CSR in the textile business. In order to get an idea of some of the industry wide activities and obstacles, this work contains an exemplary description of the CSR work of the two leading fashion retailers, Bestseller and H&M, using their company home pages as well as their current and previous annual reports and an outline of their reflection of the current stage of affairs regarding Human Development. Based on the findings from the homepages of H&M and Bestseller and the companies’ claim, different researched articles and the latest accidents in the news, eleven different interview questions were developed, regarding the actual textile production situation in the RGM industry. These questions are being used for semi-structured in-depth interviews with three different experts of the International Labour Organization, the German NGO Südwind Institute and the Confederation of the German Textile and Fashion Industry to get first hand information about the already achieved progress of the working conditions, as well as crucial driving forces and challenges within the Human Development “sector” of CSR in low wage countries. By considering all the different information, this work finally reveals grievances in CSR and gives proposals for improving the working conditions of the textile factory workers in emerging countries. Findings – The findings show the complexity and necessity of a controversy about CSR approaches in the textile and garment sector of developing countries. Recent accidents and different investigations by independent organizations are supporting the impression of an existing gap between the CSR policies of fashion companies on the one hand and the reality in the firms on the other hand. Different NGO’s are complaining about insufficiently implemented approaches and Codes of fashion brands and retailers within the supply chain. This work provides different suggestions for improving the working conditions of the textile factory workers in emerging countries. Possible ways for a human friendlier textile production are for example the strengthening of trade unions and worker advocacies, the ensuring of a social dialogue and closer collaborations between all the different stakeholders within the industry - including the governments, as well as more legal bindings and stricter regulations. Research limitations/ implications – The findings from this study are limited to the “sector” of Human Development and most of the results or hypotheses are not conclusively audited, due to the difficult validation. Additionally, the study is mainly focusing on the worker situation in selected low wage countries and does not provide global conclusions. Further research should aim to gain even further insights, for instance on a local company or local supplier level.

Fecundability is regarded as one of the important parameters of fertility performance of the married women. Due to the complex nature of fecundability, we have attempted to estimate mean fecundability from the first conception interval. The first conception intervals have been obtained utilizing the data extracted from the 1999-2000 Bangladesh Demographic and Health Survey(BDHS). The purpose of the study is to estimate mean fecundability by various classical and non classical methods of estimation. Since the cohort of women is not homogeneous, we have attempted to estimate the mean natural fecundability from the Beta Distribution with parameters a and b. For the classical method, the parameters are estimated by the method of moments and method of maximum likelihood. For the non classical methods, standard, hierarchical, and empirical Bayes were used to estimate the mean fecundability. By using the Bangladesh Demographic and Health Survey(1999-2000) Data, the mean conception delay of the Bangladeshi women has been found to be 21.31 months after their first marriage and mean fecundability is 0.04692. This mean fecundability is computed as the reciprocal of mean conception delay. The theoretical arithmetic mean fecundabilities were found to be 0.058 and 0.066 employing the method of moments and method of maximum likelihood. The standard Bayes estimate of fecundability is 0.04696 while the Hierarchical and Empirical Bayes estimate of fecundability are 0.04694 and 0.04692. To compute the Hierarchical Bayes estimate, we used the Gibbs Sampler technique. In the case of Hierarchical Bayes method, we model the prior in terms of another random variable but in Empirical Bayes method, we estimate the parameter instead of attempting to model the parameter from the data. In this study, we have observed that the variation in mean fecundability is negligible whatever the methods of estimation be. / Department of Mathematical Sciences

The thesis aimed to investigate the current situation of food security and initiatives by main actors in Dhaka, Bangladesh, with urban poor in focus. A qualitative study with the actors of food security and the urban poor is the basis of this research’s result complementing with previous studies on this topic. Income of the urban poor in Bangladesh is very low compare to the food price which is one of the main reasons why urban poor are not food secure in Dhaka city. There are many organizations working on income generating approaches in urban Dhaka but the work is too small to have an impact on the current situation of food security. Lack of social safety net is another reason identified for food insecurity in urban Dhaka. The government is provided low priced rice and wheat to the urban poor yet again this only covers 1 percent of the urban slums. Due to lack of resource sustainable development is not included in in the process of ensuring food security in urban Dhaka.

In order to improve the water situation in rural areas of Bangladesh, a research group at the University of Dhaka has been developing low cost domestic methods to remove pathogens from surface water through pasteurisation using free solar energy. Pasteurisation is a process in which water is heated to approximately 60 °C and maintained for about 30 minutes to destroy pathogens. In these methods, the water is also exposed to UV-light from the sunshine, which causes destruction of diarrhoeal pathogens at temperatures somewhat lower than required in normal pasteurisation. However, despite many advantages these devices need to be installed for each time of use. Recently, a semi-permanent device has been developed which is expected to be more user friendly. The objective of this Master thesis has been to study and optimize the low cost semi-permanent device that can deliver safe drinking water to people in rural areas. Two test devices were constructed to determine the most effective treatment e.g. temperature, time, solar radiation, user-friendliness and cost. To replicate the results from the solar heating tests a model, based on the solar radiation and convective heat loss from the device, was used. The model was also able to determine the time duration at a certain solar radiation level to estimate when the water is safe to drink. The results revealed that the performance of the device depends on thickness of the insulation and thickness of the air gap. This is because the most important factors to achieve safe drinking water are solar radiation and time. The modelling indicated that the measured water temperature corresponds well with the calculated water temperature and also showed that the lowest required solar radiation is 390 W/m2 to reach drinking water criteria, at an air temperature of 25 °C. A study of microbiology showed that the semi-permanent low cost device could purify surface water to a safe level.
