Customers' attitude towards agro based benefits provided by the telecommunication operators in Bangladesh

The main objective of this research is to find out attitude of users only towards agro based benefits provided by telecommunication operators in Bangladesh. Agriculture is the most important sector of the economy of Bangladesh which provides 63% employment and contributing 18.6% to the national GDP. But unfortunately the farmer's community is one of the most deprived ones in the country and frequent access to information remains one of the crying needs for a long time period. It can enable them to enhance their quality of life. It has been argued that telecommunication operators can come to aid in this respect. Telecommunications operators have already expanded their services and provided specialized agro-based services to the farmers. It also explored the characteristics of the user's and their perception. Data were collected from 120 respondents who were the users of telecommunication operators in Bangladesh. The data were collected through a structured interview schedule. Evidence from interviews suggests that most of the users were young, had little farming experience with small farm size and from small to medium families. These services were treated helpful to overcome their obstacles to information collection but still not efficient like the means they use to collect information traditionally. They want information in various fields of agriculture especially in the area of price, weather information, cultivation technique, disease treatment, fertilizer dose etc. Small farmers found it as a very effective any of information service especially in case of emergency situation and due to its cost effectiveness. But the mechanism need to use this services found sometimes difficult especially for the illiterate farmers. From this research, students other researchers and policy makers will get an insight about the ‘Users attitude towards agro based services provide by the telecommunication operators in Bangladesh.

Climate proofing infrastructure in Bangladesh : the incremental cost of limiting future inland monsoon flood damage

Two-thirds of Bangladesh is less than 5 meters above sea level, making it one of the most flood prone countries in the world. Severe flooding during a monsoon causes significant damage to crops and property, with severe adverse impacts on rural livelihoods. Future climate change seems likely to increase the destructive power of monsoon floods. This paper examines the potential cost of offsetting increased flooding risk from climate change, based on simulations from a climate model of extreme floods out to 2050. Using the 1998 flood as a benchmark for evaluating additional protection measures, the authors calculate conservatively that necessary capital investments out to 2050 would total US$2,671 million (at 2009 prices) to protect roads and railways, river embankments surrounding agricultural lands, and drainage systems and erosion control measures for major towns. With gradual climate change, however, required investments would be phased. Beyond these capital-intensive investments, improved policies, planning and institutions are essential to ensure that such investments are used correctly and yield the expected benefits. Particular attention is needed to the robustness of benefits from large-scale fixed capital investments. Investments in increased understanding of risk-mitigation options and in economic mobility will have especially high returns.Hazard Risk Management,Transport Economics Policy&Planning,Climate Change Mitigation and Green House Gases,Science of Climate Change,Climate Change Economics

Antidiabetic Effects of Momordica Charantia (Karela) in Male Long Evans Rat

The hypoglycemic effect of Momordica charantia (Karela) has been reported from many laboratories. To our knowledge, the underlying biochemical mechanism of action of this important clinical effect has not been reported. During the course of investigation of this aspect of the herbal fruit, it was reported from our laboratory that ethanolic extract of Momordica charantia suppressed gluconeogenesis in normal and streptozotocin (STZ) induced diabetic rats by depressing the hepatic gluconeogenic enzymes fructose-1,6-bisphosphatase and glucose-6-phosphatase. The herbal extract had also enhanced the activity of glucose-6-phosphate dehydrogenase, the rate-limiting enzyme of hexose monophosphate shunt (a pathway for the oxidation of glucose)

Academic Use of Smartphones in Secondary Level Education in Bangladesh: A Non-Parametric Approach

This study aims to examine the use of smartphones for educational purposes and the acceptance of online learning among secondary students. To investigate the academic utilization of smartphones among secondary students in Bangladesh, a sample of 384 students from different districts of Bangladesh were surveyed. The survey was conducted using a selfadministered, semi-tailored computerized questionnaire. The collected data was analyzed using IBM SPSS statistics 26 and the Mann-Whitney U test. The findings indicate that male students used smartphones for educational purposes with greater confidence and less difficulty than female students. On the other hand, students in 8th to 10th grade classrooms reported a greater willingness to use smartphones for academic purposes, with urban students being more enthusiastic than their rural peers. The study’s findings have implications for the government, policymakers, educators, and non-governmental organizations (NGOs). They highlight the importance of ensuring equal access to resources and tools that support academic success, as well as addressing the adverse effects of excessive smartphone usage. In addition, the government and NGOs should prioritize the elimination of inequities between rural and urban areas and provide subsidies to rural students
