Abstract

­Large-scale mass poisoning through arsenic contaminated groundwater is a global concern and Bangladesh is among the countries exposed to high concentrations of arsenic in groundwater. As arsenic is a widespread contaminant, several studies have been conducted on it but only a few of these studies were held on micro regions by assessing its role on water quality index. In this study, the source and mobilization of arsenic, its effect on soil and plant, level and consequence of toxicity in human health along with current and potential methods to eliminate arsenic from groundwater in Bangladesh were reviewed based on previous researches. Along with the review, an experimental study was also carried out in an arsenic prone region of Bangladesh named Faridpur Sadar Upazila to delineate the role of arsenic in contamination by generating two synthetic scenarios where water quality was measured by the weighted arithmetic water quality index (WQI) method. From the review it was found that, both geogenic, as well as anthropogenic sources, contribute to arsenic affluence in groundwater in Bangladesh. The most accepted theory states that the Himalayan is the primary geogenic source of arsenic in the Bangladesh. Arsenic arrived in the aquifer transported with sediments which eventually releases into groundwater by several biogeochemical processes. This arsenic-contaminated groundwater is extensively used for drinking purpose and irrigation resulting in accumulation of arsenic in human body, soils and plants.  Moreover, the accumulated arsenic in soil and plants transmits into the human body jeopardizes human health. Though, several arsenic removal technologies are now in practice in Bangladesh, more eco-friendly and convenient methods may be utilized to attenuate the level of toxicity.  The experimental study revealed that, if the arsenic amount was reduced from the present condition, the overall WQI increases considerably. At one location, the index changed from category E to category B while considering a synthetic scenario of no arsenic in water. This indicates that arsenic is the key pollutant of groundwater in the area. This paper expects the kind attention of the local people and policymakers about the severity of arsenic pollution in the region.

Abstract

­Social business hubs play an important role in facilitating social innovation and support social entrepreneurs to deliver social benefits to the wider community. This paper aims to firstly identify and evaluate the key success factors of social business hubs in the Middle East with the focus on Jordan, Lebanon and Iraq, secondly, identify what successful social hubs offer, and thirdly, identify the challenges facing social business hubs in the region. In-depth interviews with eight social business hub managers were conducted using a pre-designed questionnaire. The findings were interesting and meaningful and show the impact severity of the COVID-19 pandemic on the infrastructure of the social business hubs. Networking and collaboration seem to be the predominant success factor for social business hubs. Finally, we observe that social business hubs in the region are facing many challenges; the main two are lack of government support and funding issues.

Abstract

­

In this paper, we attempted to test whether the governance has a positive impact on the structural change in SSA or not.  For the cause, we used the six indexes of the Institutional Quality namely Government Effectiveness, Rule of Law, Control of Corruption, Political Stability and Absence of Violence/Terrorism, Regulatory Quality, Voice of Accountability to see their impact on the structural change in SSA. We use 46 SSA countries from worldwide governance indicator of World Bank from 1996 to 2016 in a Generalized Method of Moment and Generalized Least Square regressions. The results show that only the Government Effectiveness is positively affecting the value added (proxy of structural change) of three sectors (agriculture, industry and service) of the SSA economies.   Some affect positively one sector and negatively another sector, while the rest are insignificant for one sector and negative for other as example. Our results show that more efforts need to be done for the betterment of the institutional quality considering each sector’s particularity.

Abstract

­

Bangladesh has been taken into consideration as a climate vulnerable country and the impacts of climate change increase threats of adverse condition in agricultural production. This study is primarily based on assessing farmer’s adaptive capacities to adaptation techniques, its determinants and problems of taking adaptations. It’s an empirical study that is conducted on the basis of 100 mango producers lived in the Chapai Nawabganj district. Adaptive Capacity Index (ACI) is utilized to calculate the adaptive capacity of farmers and using Multiple Regression Model (MRM) the determinants of adaptive capacities are identified based on OLS method. Another comprehensive index called Problem Confrontation Index (PCI) is also applied to rank the problems confronted by farmers to take adaptation techniques. The findings of this study reveal that farmer’s average adaptive capacity is moderate in degree in the study area which is 0.64 and 73% farmers are moderate level adapters. In addition, regression analysis reveals that the variables education, training, family size and weekly mango orchard visit have significant impact on the adaptive capacities of mango producers lived in the study area. It is also found that “lack of agricultural loan” ranked top and appears to be the most intense trouble of the mango producers to take adaptation techniques in the region studied. Finally, this study suggests that government should formulate proper policy to enhance adaptive capacities of farmers in Bangladesh.

Abstract

­

The study’s overall goal is to assess the influence of conflict management on managerial performance at the Ministry of Finance and Planning, and it employs a descriptive research methodology. The study employed a sample size of 44 respondents, which included senior managers, line managers, and support workers. The respondents were selected using a simple random sampling method and purposive sampling. In this study, questionnaires were employed as the primary data gathering tool. The data gathered in the field was analyzed using the Statistical Package for Social Sciences (SPSS) Version 16.0, which included descriptive statistics like percentages as well as inferential statistics like frequencies percentages analyses. According to the findings of this study, the majority of respondents believe that dialogue influences conflict management and managerial performance. They also believe that involving employees in conflict resolution leads to the achievement of a mutually optimal solution, implying that using an integrating strategy to manage conflicts improves managerial performance. The study concludes that conflict management strategies and managerial performance are linked, and that the most commonly used strategies are integrating, avoiding, and obliging. It is recommended that the Ministry of Finance and Planning highlight and use at least two or one strategy to ensure objectivity.

Abstract

­

Water treatment is crucial for agricultural production in order to maximize its value. It is suitable for use in agriculture, construction, and advanced technologies, and new technologies, especially in the field of IT. This paper presents an intelligent rule system based on a multi-agent architecture using fuzzy logic. This paper really solves the problem of regulating the supply of cold and hot water in industry. The problem of the lack of a clear mechanism for regulating water for use in the industrial process has led to unsatisfactory results in the production capacity of the financial sector. This can be solved through the development of the accessory function, which is an analysis of the causes of problems in the management of cold and hot water used in the manufacturing industry. The design of the accessory function, which consists of detecting deviations in the amount of liquid that had to pass through the hot and cold water tanks for industrial applications and necessity. Development of a smart rule that will control the amount of liquid in hot and cold water tanks, in trains, these are rules that must strictly follow the control format and consists in creating and developing a model of the water management process to increase production using an intelligent agent. The result is an increased level of performance where the intelligent agent that was used is concerned.

The Effect of Public Debt Composition and Government Expenditure on Economic Growth of Kenyan Government Angela Mucece Kithinji

The Effect of Public Debt Composition and Government Expenditure on Economic Growth of Kenyan Government

Author (s)

Angela Mucece Kithinji

Abstract

­

Many developing countries have high levels of public debt many of which do not have sufficient resources to meet the public debt obligations. The Kenya government has reported high debt levels the debt levels of which do not assume a downward trend but instead continue escalating from one year to another while not downplaying the role of the its huge expenditure. The major concern is whether some developing countries such as the Kenya government should raise more of foreign debt which is cheaper in terms of interest costs while adhering to the conditionality of lending countries or whether the country should borrow domestically despite the higher interest costs. It was thus feasible to establish the influence of the composition of the Kenya public debt and government expenditure on the country’s economic growth. The study employed a causal research design. The period under study ranged from 2002 to 2017. The study used secondary data which was extracted from the National Bureau of Statistics, and National Economic Surveys which were available at the Government of Kenya website. Descriptive statistics was used to test the magnitude of the study variables. Regression analysis was used to establish the effect of public debt composition and government expenditure on economic growth in Kenya. The study established that both public debt composition and government expenditure had significant effect on economic growth of the country when tested individually. However, the findings further revealed that on the combined effect of the two independent variables, only government expenditure was found to influence economic growth unlike domestic public debt. The study therefore recommended that the government of Kenya should take precautions when engaging borrowing domestically and by extension in any form of borrowing.
