It can be described as a new face of self-awareness for female characters that will ultimately facilitate their journey on the path to self-independence. The study scrutinizes the novel The God of Small Things (1997) through female characters who are curving emancipation in the realm of patriarchal oppression. Most Indian women face current risks stemming from traditional gender roles. The worst social and economic conditions for Indian women were described in this way by Arundhati Roy. As a divorced woman, the life of Ammu with her parents and brother was not comfortable, and they treated her and her children in an awful way. Instead of these ill-treatments, some women desire to be emancipated from existing prejudiced social norms. The study forms a pragmatic combin...

How does the Audio-lingual Method effective in Bangladesh? The objective of this study is to explain the effectiveness of the Audio-lingual method in Bangladesh. It is expected that the result will provide a deeper understanding of the uses of the Audio-lingual Method and can be used as a teaching method for English language teachers and students. The study implemented an experiment test to accomplish the objectives. The participants of this study were the student of class 8 to 10. The academies of this study were from various secondary level Schools at Tongi in Bangladesh. The number of the School was five and our main purpose was to find out the problems of the audio-lingual method in the field of secondary education. As most of the teachers and students do not know about the method thus the research was fully unable to explore the problems of the audio-lingual method in terms of Bangladesh. keywords: Audio-lingual method, Secondary education in Bangladesh, English teaching method.

III-V semiconductors, InGaN alloy are very encouraging candidates for solar cells. In recent years, InGaN alloy provides the ability to tune the band gap for solar energy conversion. In this work, InGaN based QW and QD solar cells have been theoretically studied and evaluated the performance with various parameters for achieving high efficiency. Short circuit current density, open circuit voltage and efficiency are calculated with the dependencies of band gap energy. The efficiency is found to be 46.38% for InGaN based QW solar cell. The calculations show that the inclusion of the QDs in the intrinsic region does indeed enhance short circuit current without significant losses in the open circuit voltage and result significantly improved cell efficiency. Comparison of InGaN based MQW and QD solar cell implies that InGaN based QD solar cell offers the highest efficiency.

Research paper thumbnail of The impact of co-management on household income and expenditure: An empirical analysis of common property fishery resource management in Bangladesh

Ocean & Coastal Management, 2012

As a result of the continuation of the traditional leasing system, the elites and influential individuals captured and controlled the water bodies, and, as a consequence, low income individual lost their rights to fish and work in these water bodies. In 1995, the Bangladesh Department of Fisheries initiated a new management system called CBFM where local poor people were involved in the management process and received rights to fish in the common property water bodies. This study examined the impact of the CBFM-2 project on the income, expenditure and inequality of the fishing community and determines the relationship between poverty and inequality. Following simple random sampling, a representative sample of 196 fisher households comprising 101 CBFM (target) fishers and 95 non-CBFM (control) fishers were selected from Hakaluki and Halir haors of the Moulouvibazer and Sunamgonj districts, respectively. A propensity score matching method was used for impact evaluation. The results show that the CBFM-2 project has a positive and significant impact on fisher's income and household expenditure when poor fishers are involved in the co-management system. The results also reveal that inequality is not a major problem in the study areas, and no significant changes in the income and expenditure distribution has taken place following the project implementation. Finally, the results reveal that inequality and poverty are negatively related in the study area.

The fibers soaked in different concentration (1-10%) of monomer þ MeOH solution along with photoinitiator Irgacure 907 [2%] were cured under ultraviolet (UV) lamp at different UV radiation intensities (2-14 passes). Concentration of monomer at different radiation intensities was optimized with extent of mechanical properties such as polymer loading, tensile strength, and elongation at break. Enhanced tensile strength (268%) and elongation at break (110%) were achieved by the polymer treated fibers than untreated virgin fibers. We observed that, henequen fibers treated by 3% EA showed better physico-mechanical properties than those treated by 5% HEA. The tensile properties of henequen fibers treated by 3% EA can be enhanced by adding aloxysilane; 3-(trimethoxysilyl) propylmethacrylate additives with bulk monomer EA (3%). The degradability of the treated and untreated fibers due to accelerated weathering were also studied and it has been found that surface modified henequen fibers produced more resistivity towards different weathering conditions than untreated fibers.

This paper used data from the 2007 Bangladesh Demographic Health Survey. The analyses were based on the responses of 3374 ever-married men. Exposure to IPV was determined by men's self-reports of witnessing inter-parental violence in childhood. We used adjusted binary logistic regression models to assess the influence of exposure on husbands' perpetration of IPV and their endorsement of attitudes justifying wife beating. Nearly 60% of men reported violent behaviour towards an intimate partner and 35.7% endorsed attitudes justifying spousal abuse. Men who witnessed father-to-mother violence had higher odds of reporting any physical or sexual IPV (adjusted OR [AOR] = 3.26; 95% CI = 2.61, 4.06). Men who had witnessed father-to-mother violence were also 1.34 times (95% CI = 1.08, 1...

Intimate partner violence (IPV) is regarded as one of the potential psychosocial risk factors that may negatively affect exclusive breastfeeding (EBF). This study aimed to explore the influence of psychosocial factors including IPV on EBF. Cross-sectional survey data was collected from October 2015 to January 2016 in Chandpur District of Bangladesh from 426 married women, aged 15-49 years, who had at least one child 6 months of age or younger. Multivariate logistic regression models were used in order to investigate whether women who experienced IPV after childbirth, as well as other risk factors such as postpartum depression (PPD) and childhood sexual abuse, were more likely to face difficulties with EBF compared with women who had not experienced these same risk factors. Whilst the initiation rate of breastfeeding was 99.3%, at the time of the woman's interview, the overall EBF rate had fallen to 43.7%. Based on the adjusted model, women who experienced physical IPV (AOR 0.17, 95% CI [0.07, 0.40]) and psychological IPV (AOR 0.51, 95% CI [0.26, 1.00]) after childbirth and women who reported childhood sexual abuse (AOR 0.32, 95% CI [0.13, 0.80]) and PPD (AOR 0.20, 95% CI [0.09, 0.44]) were significantly less likely to exclusively breastfeed their infants than those who had not reported these experiences. Moreover, women with an intended pregnancy and high social support exhibited a higher likelihood of EBF. Our results suggest that preventing or reducing the occurrence of physical IPV, PPD and childhood sexual abuse may improve the EBF duration. Support from family members can assist in this process.

The 2011 Bangladesh Demographic and Health Survey, conducted from 8 July to 27 December 2011. Selected urban and rural areas of Bangladesh. A total of 2197 ever-married women living with at least one child younger than 5 years. Exposure was determined from maternal reports of high-risk fertility behaviours. We considered three parameters, maternal age at the time of delivery, birth order and birth interval, to define the high-risk fertility behaviours. Chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition among women were the outcome variables. A substantial percentage of women were exposed to have a high-risk fertility pattern (41·8 %); 33·0 % were at single high-risk and 8·8 % were at multiple high-risk. After adjusting for relevant covariates, high-risk fertility behaviours were associated with increased likelihood of chronic undernutrition (adjusted relative risk; 95 % CI: 1·22; 1·03, 1·44), anaemia (1·12; 1·00, 1·25) and the coexistence of anaemia and undernutrition (1·52; 1·17, 1·98). Furthermore, multiple high-risk fertility behaviours appeared to have more profound consequences on the outcome measured. Maternal high-risk fertility behaviours are shockingly frequent practices among women in Bangladesh. High-risk fertility behaviours are important predictors of the increased likelihood of women's chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition.

Research paper thumbnail of Spectra of Alternative Therapies of Hypercholesterolemia by Dietary Bioactives: Emphasis on Nutrigenomics of Polyphenols

Though current therapeutic strategies of hypercholesterolemia meet the present treatment demand but their efficacy is in question as well as the emergence of medicinal resistance. Demand of new therapeutic strategies is obvious while alternative therapeutic strategies are highly promising. Alternative therapeutic approaches are must in that respect but current experimental findings are still ambiguous and scarce. Several transcription factors playing vital role in cholesterol homeostasis and hypercholesterolemia change their expression profile in response to dietary polyphenols like PPARs, SREBPs, SHP, LXR, FXR etc. Function and expression of a number of proteins considered as therapeutically important regarding hypercholesterolemia like HMG-CoA reductase, CYP7A1, CETP, ABCA1 etc. are modulated by the dietary polyphenols. Experimental paradigm lacks to show the effect of polyphenols in metabolite profile under hypercholesterolemia. Therefore, alternative therapeutic approaches of the hypercholesterolemia under the shade of nutrigenomics by dietary bioactive like polyphenols should be focused and flourished for development of more efficient, highly specific and natural therapeutic approaches.

Keeping this in mind, the objectives of this study were to assess the effectiveness of OHE program in: 1) increasing oral health knowledge, attitude, and practices and 2) decreasing the prevalence of untreated dental caries among 6-8 grade school students in Bangladesh. This intervention study was conducted in Araihazar Thana, Narayanganj district, Bangladesh during April 2012 to March 2013. The total participants were 944 students from three local schools. At baseline, students were assessed for oral health knowledge, attitude and practices using a self-administered structured questionnaire and untreated dental caries was assessed using clinical examination. Follow up study was done after 6 months from baseline. McNemar's chi-square analysis was used to evaluate the impact of OHE program on four recurrent themes of oral health between the baseline and follow-up. Multiple logistic regression analyses were used to determine the impact of the intervention group on our outcome variables. Significant improvement was observed regarding school aged adolescents' self-reported higher knowledge, attitude and practices scores (p < 0.001) at follow-up compared with baseline. The prevalence of untreated dental caries of the study population after the OHE program was significantly (p < 0.01) reduced to 42.5 %. Multiple logistic regression analyses showed that the OHE intervention remained a significant predictor in reducing the risk of untreated dental caries (adjusted odds ratio [AOR] =0.51; 95 % confidence interval [CI] = 0.37, 0.81). In the follow-up period participants were 2.21 times (95 % CI = 1.87, 3.45) more likely to have higher level of knowledge regarding oral health compared to baseline. Compared with baseline participants in the follow-up were 1.89 times (95 % CI = 1.44-2.87) more likely to have higher attitude towards oral health. In addition, OHE intervention was found to be significantly associated with higher level of practices toward oral health (AOR = 1.64; 95 % CI = 1.12, 3.38). This study indicated that OHE intervention was effective in increasing i) knowledge, ii) attitude, and iii) practices towards oral health; it also significantly reduced the prevalence of untreated dental caries among school aged adolescents from grade 6-8 in a deprived rural area of Bangladesh.

Intimate partner violence (IPV) is regarded as one of the potential psychosocial risk factors that may negatively affect exclusive breastfeeding (EBF). This study aimed to explore the influence of psychosocial factors including IPV on EBF. Cross-sectional survey data was collected from October 2015 to January 2016 in Chandpur District of Bangladesh from 426 married women, aged 15-49 years, who had at least one child 6 months of age or younger. Multivariate logistic regression models were used in order to investigate whether women who experienced IPV after childbirth, as well as other risk factors such as postpartum depression (PPD) and childhood sexual abuse, were more likely to face difficulties with EBF compared with women who had not experienced these same risk factors. Whilst the initiation rate of breastfeeding was 99.3%, at the time of the woman's interview, the overall EBF rate had fallen to 43.7%. Based on the adjusted model, women who experienced physical IPV (AOR 0.17, 95% CI [0.07, 0.40]) and psychological IPV (AOR 0.51, 95% CI [0.26, 1.00]) after childbirth and women who reported childhood sexual abuse (AOR 0.32, 95% CI [0.13, 0.80]) and PPD (AOR 0.20, 95% CI [0.09, 0.44]) were significantly less likely to exclusively breastfeed their infants than those who had not reported these experiences. Moreover, women with an intended pregnancy and high social support exhibited a higher likelihood of EBF. Our results suggest that preventing or reducing the occurrence of physical IPV, PPD and childhood sexual abuse may improve the EBF duration. Support from family members can assist in this process.

The 2011 Bangladesh Demographic and Health Survey, conducted from 8 July to 27 December 2011. Selected urban and rural areas of Bangladesh. A total of 2197 ever-married women living with at least one child younger than 5 years. Exposure was determined from maternal reports of high-risk fertility behaviours. We considered three parameters, maternal age at the time of delivery, birth order and birth interval, to define the high-risk fertility behaviours. Chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition among women were the outcome variables. A substantial percentage of women were exposed to have a high-risk fertility pattern (41·8 %); 33·0 % were at single high-risk and 8·8 % were at multiple high-risk. After adjusting for relevant covariates, high-risk fertility behaviours were associated with increased likelihood of chronic undernutrition (adjusted relative risk; 95 % CI: 1·22; 1·03, 1·44), anaemia (1·12; 1·00, 1·25) and the coexistence of anaemia and undernutrition (1·52; 1·17, 1·98). Furthermore, multiple high-risk fertility behaviours appeared to have more profound consequences on the outcome measured. Maternal high-risk fertility behaviours are shockingly frequent practices among women in Bangladesh. High-risk fertility behaviours are important predictors of the increased likelihood of women's chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition.

Though current therapeutic strategies of hypercholesterolemia meet the present treatment demand but their efficacy is in question as well as the emergence of medicinal resistance. Demand of new therapeutic strategies is obvious while alternative therapeutic strategies are highly promising. Alternative therapeutic approaches are must in that respect but current experimental findings are still ambiguous and scarce. Several transcription factors playing vital role in cholesterol homeostasis and hypercholesterolemia change their expression profile in response to dietary polyphenols like PPARs, SREBPs, SHP, LXR, FXR etc. Function and expression of a number of proteins considered as therapeutically important regarding hypercholesterolemia like HMG-CoA reductase, CYP7A1, CETP, ABCA1 etc. are modulated by the dietary polyphenols. Experimental paradigm lacks to show the effect of polyphenols in metabolite profile under hypercholesterolemia. Therefore, alternative therapeutic approaches of the hypercholesterolemia under the shade of nutrigenomics by dietary bioactive like polyphenols should be focused and flourished for development of more efficient, highly specific and natural therapeutic approaches.

Keeping this in mind, the objectives of this study were to assess the effectiveness of OHE program in: 1) increasing oral health knowledge, attitude, and practices and 2) decreasing the prevalence of untreated dental caries among 6-8 grade school students in Bangladesh. This intervention study was conducted in Araihazar Thana, Narayanganj district, Bangladesh during April 2012 to March 2013. The total participants were 944 students from three local schools. At baseline, students were assessed for oral health knowledge, attitude and practices using a self-administered structured questionnaire and untreated dental caries was assessed using clinical examination. Follow up study was done after 6 months from baseline. McNemar's chi-square analysis was used to evaluate the impact of OHE program on four recurrent themes of oral health between the baseline and follow-up. Multiple logistic regression analyses were used to determine the impact of the intervention group on our outcome variables. Significant improvement was observed regarding school aged adolescents' self-reported higher knowledge, attitude and practices scores (p < 0.001) at follow-up compared with baseline. The prevalence of untreated dental caries of the study population after the OHE program was significantly (p < 0.01) reduced to 42.5 %. Multiple logistic regression analyses showed that the OHE intervention remained a significant predictor in reducing the risk of untreated dental caries (adjusted odds ratio [AOR] =0.51; 95 % confidence interval [CI] = 0.37, 0.81). In the follow-up period participants were 2.21 times (95 % CI = 1.87, 3.45) more likely to have higher level of knowledge regarding oral health compared to baseline. Compared with baseline participants in the follow-up were 1.89 times (95 % CI = 1.44-2.87) more likely to have higher attitude towards oral health. In addition, OHE intervention was found to be significantly associated with higher level of practices toward oral health (AOR = 1.64; 95 % CI = 1.12, 3.38). This study indicated that OHE intervention was effective in increasing i) knowledge, ii) attitude, and iii) practices towards oral health; it also significantly reduced the prevalence of untreated dental caries among school aged adolescents from grade 6-8 in a deprived rural area of Bangladesh.

Cross-sectional nationally representative study. Bangladesh. This paper used data from the 2011 Bangladesh Demographic Health Survey. The analyses were based on the responses of 339 diabetes hypertensive individuals. Diagnosis, treatment and control of hypertension. The age-adjusted prevalence of hypertension in diabetes individuals was 38.4% in the study population. Among diabetic hypertensive subjects only 65.7% had been diagnosed, 58.4% were receiving treatment and 42% controlled their hypertension. Individuals from high socioeconomic status (AOR 2.60; 95% CI 1.16-5.83) had an increased likelihood of reporting diagnosis of hypertension. Individuals from medium (AOR 2.22; 95% CI 1.11-4.46) and high socioeconomic status (AOR 3.47; 95% CI 1.59-7.58) had increased chance of receiving treatment. In addition, individua...
