Age-related risk factors and severity of SARS-CoV-2 infection: A systematic review and meta-analysis
(Pacini Editore S.p.A./AU-CNS, 2021-07-01) Rahman, Mohammad Meshbahur; Bhattacharjee, Badhan; Farhana, Zaki; Hamiduzzaman, Mohammad; Chowdhury, Muhammad Abdul Baker; Hossain, Mohammad Sorowar; Siddiqee, Mahbubul H.; Islam, Ziaul; Raheem, Enayetur; Uddin, Jamal; Department of Biotechnology
Objectives. We aimed to estimate the prevalence of reported symptoms and comorbidities, and investigate the factors associated with age of the SARS-CoV-2 infected patients. Methods. We performed a systematic review with meta-analysis (PROSPERO registration: CRD42020182677) where the databases (PubMed, SCOPUS, EMBASE, WHO, Semantic Scholar, and COVID-19 Primer) were searched for clinical studies published from January to April, 2020. Initially, the pooled prevalence of symptoms and comorbidity of COVID-19 patients were estimated using random effect model and the age –related factors were identified performing multivariate analysis [factor analysis]. Results. Twenty-nine articles with 4,884 COVID-19 patients were included in this study. Altogether, we found 33 symptoms and 44 comorbidities where the most frequent 19 symptoms and 11 comorbidities were included in the meta-analysis. The fever (84%), cough/dry cough (61%), and fatigue/weakness (42%) were found more prevalent while acute respiratory distress syndrome, hypertension and diabetes were the most prevalent comorbid condition. The factor analysis showed positive association between a cluster of symptoms and comorbidities with patients’ age. The symptoms comprising fever, dyspnea/shortness of breath, nausea, vomiting, abdominal pain, dizziness, anorexia and pharyngalgia; and the comorbidities including diabetes, hypertension, coronary heart disease, COPD/lung disease and ARDS were the factors positively associated with COVID-19 patient’s age. Conclusion. As an unique effort, this study found a group of symptoms (fever, dyspnea/shortness of breath, nausea, vomiting, abdominal pain, dizziness, anorexia and pharyngalgia) and comorbidities (diabetes, hypertension, coronary heart disease, COPD/lung disease and ARDS), associated with the age of COVID-19 infected patients. © Copyright by Pacini Editore Srl, Pisa, Italy.
Food insecurity and conflict events in Africa
(Walter de Gruyter GmbH, 2018-01-01) Murshed, Syed Mansoob; Badiuzzaman, Muhammad; Hasan, Rashel; Centre for Peace and Justice
The aim of this paper is to examine the relationship between food insecurity and conflict events short of war in Africa, taking account of a host of mediating factors, including the degree of inequality, the level of development, democratic quality, quality of governance and the degree of government expenditure, which we incorporate into our analysis. Our results suggest that food price volatility does contribute significantly to conflict events measured by political events in Africa (ACLED). Greater democracy can engender more conflict, but in a non-linear fashion. The broader V-DEM participatory index of democracy also encourages more protest. Our governance variables are significant, emphasising the salience of state capacity in this regard. An innovation of our study is the inclusion of inequality. We deploy two metrics of vertical inequality: the GINI coefficient and the broader V-DEM egalitarian index. The GINI index of income inequality has a counter-intuitive statistically insignificant sign, suggesting that greater income equality or middle-class share of income results in greater political unrest. We also utilise political measures of inter-group horizontal inequality which significantly engender conflict risk. © 2018 Walter de Gruyter GmbH, Berlin/Boston.
Is there a linkage between sustainable development and market access of LDCs?
(De Gruyter, 2013-10-01) Tania, Sharmin Jahan; School of Law
This article revisits the decades-long trade-sustainable development debate in the context of Rio+20 and its endorsement of green economy policy. It aims to grapple with the possible linkages between LDCs' market access regime and the concept of sustainable development itself. Conflicting perceptions of developed and least developed country (LDC) members of the WTO as to the conceptual basis of sustainable development, this article argues, explain the challenges LDCs face in the form of impediments to their market access. By examining the specific market access issues, this article reveals how developed countries' concerns for sustainable development turn out to be market access barriers for LDCs. As the call for transition to green economy could exacerbate some of these concerns of LDCs, the article suggests a common ground, where a balanced trading regime can be most productively envisioned through a reasoned discourse of market access for LDCs linked with a conceptual route of sustainable development.
Islamic social finance in Bangladesh: Challenges and opportunities of the institutional and regulatory landscape
(De Gruyter, 2020-01-01) Uddin, Tanvir Ahmed; Mohiuddin, Md Fazla; BRAC Business School
From the end of World War Two, the core methodology of law and development projects has been to transplant the best legal institutions of Western capitalism to poor and emerging economies. In many post-colonial contemporary Muslim-majority countries, such programs have not adequately engaged with local legal systems, cultures and traditions. Contrary to the restrictive modernist approach to law and development, and inspired by the Sharia, there are numerous Islamic social finance mechanisms that can be utilised for poverty alleviation and their existence is evident across Bangladesh. These cover the full spectrum of philanthropic to financing, investments and insurance built upon Sharia norms and principles. Unfortunately, the true potential of Islamic social finance is considerably constrained by the weak regulatory and policy environment. Islamic social finance does not feature in national development plans, is regulated through a patchwork framework, and operates at a negligible scale. This paper provides a detailed analysis of the existing regulatory and institutional landscape of Zakah (obligatory almsgiving), awqaf (perpetual endowments), Islamic microfinance and microtakaful (microinsurance) in Bangladesh and examines the potential and challenges for Islamic social finance to reduce poverty. Thereafter, several pertinent policy and institutional recommendations are provided to effectively modernise and advance the effectiveness of Islamic social finance institutions. The methodology employed is a mixed approach incorporating literature review, legal analysis of laws and regulation and contextual analysis and field interviews among industry stakeholders. Ultimately, while private investment and initiatives are always able to support the Islamic social finance sector, this paper focuses on the extent to which the regulatory and policy environment is a crucial enabler for widespread and sustained development impact. © 2020 Law and Development Review.
Analytic relations versus syntagmatic and paradigmatic relations of vocabulary depth knowledge: Their correlation and prediction to academic reading comprehension of EFL learners
(Walter de Gruyter GmbH, 2020-01-01) Hasan, Md Kamrul; Rahman, Mohammad Mosiur; BRAC Institute of Languages
The aims of the study were to examine the correlation and prediction of different dimensions of vocabulary depth knowledge to academic reading comprehension. Students were instructed to take part in four English-language proficiency tests voluntarily. The research was carried out, administering four instruments, word associates test, morphological knowledge test, and analytic relations test to measure the depth of vocabulary knowledge. In addition, a reading comprehension test that consisted of three reading passages by Longman Test of English as a Foreign Language was adopted and administered for the current study. The results highlighted that the analytic (part-whole) relations, which represented the depth of vocabulary knowledge had the highest correlation with academic reading comprehension in comparison with morphological knowledge and combined syntagmatic and paradigmatic relations, which represented word associates test. Of all the three independent variables, analytical relations made the most statistically significant unique contribution to the prediction of the outcome variable compared to word associates test and morphological knowledge. The present study suggests that the depth of vocabulary knowledge would have practical use for students and English teachers at tertiary level and further implications for lexical researchers. © 2020 Md Kamrul Hasan and Mohammad Mosiur Rahman, published by De Gruyter 2020.
