Abstract

For a long period of time, alcohol consumption has been considered a shortcut to relieve stress and modify behavior in order to have a better time and provide a pleasant company in the eyes of other fellow companions. This is peculiarly valid for young ages who occupy a more active social life. The habit of alcohol consumption has been repeatedly evaluated and each time a different factor has appeared to play a role in its development. Alcohol beverages are consumed by students at different rates in different countries. High-income countries seem to have a wider range of consumption among students, even though their rules in alcohol consumption seem to be stricter. Meanwhile, fewer evaluations have been provided in this aspect in low-income countries. What seems to be interesting is that different circumstances that accompany living in low-income countries may obtain a valuable set of results that would provide a solid comparison between alcohol consumption habits between students in low-income countries and high-income countries. The use of such data may facilitate the implementation of alcohol policies and regulations accordingly.

Abstract

The Nigeria’s presidential democracy has largely failed to meet the yearnings of the people. The government is deficit in the much-needed infrastructural development. Indeed, most of the existing institutions are in a state of coma. A cursory examination of the political architecture depicts waste coupled with high cost of governance at all tiers of government namely local, state and federal. The cost of running presidential democracy is astronomically high bordering on extravagance in a country that is riddled with mass poverty, youth unemployment resulting in insecurity of life and property, kidnapping, armed robbery, banditry etc. The question is how can the state arrest waste and channel human and material resources towards projects that can impact positively on the socio-economic well-being of the citizenry. This work will respond to these interrogations. The paper will employ secondary data such as journals, books, magazines and periodicals to elicit information necessary for its analysis.

Abstract

There are two fundamental ideas in which Kwasi Wiredu apply his conceptual decolonization. These to him are two complementary things that are both negative and positive. In the negative sense, Wiredu’s conceptual decolonization is the process that seeks to avoid and reverse “through a critical self-awareness the unexamined assimilation” in the thoughts of contemporary African philosophers those conceptual frameworks that are found in western or other philosophical cultures that have influenced African ways of life and thought. On the positive side, conceptual decolonization to Wiredu involves the exploitation of the vast “resources” of African conceptual frameworks in philosophical exercises or reflections on all the basic and crucial problems of contemporary philosophy. This establishes Wiredu’s conceptual decolonization on historical foundation of the African problems through the process of colonialism. This historical trend in Africa has significant impacts on the whole of African system, which include education, politics, culture, science, technology, religion, culture, language, and thought patterns. These suggest that African contemporary systems are greatly influenced through the means of language, religion and politics; and the methods of science and technology. However, a critical reflection on these indicate that Wiredu’s conceptual decolonization is distinctly opposed to the principles and tenets of globalization as a socio-political concept that is inspired by economic ideas, which are anchored on technological innovativeness and development. This explains the fact that globalization is driven by technological revolutionary and innovative ideas that are powered and energized by information, computer technology (ICT). This process thrives to link the world to a common system of circuit from where all knowledge and activities in the world can be viewed and known. This characteristically shrinks the world to what has been described as “global village” in an integrative pattern. These clearly in diverse manners promote interculturalism and interdependence to the extent that no nation or continent can be seen as an island. The world through globalization has been fused in a way that Wiredu’s conceptual decolonization has been rendered a philosophical failed project with no practical and epistemological relevance. In this paper therefore, effort will be made to assess the impacts of globalization on Wiredu’s conceptual decolonization. We submit that globalization has a more pragmatic, socio-economic and political allures to prevent Wiredu’s conceptual decolonization from making any positive impact on African philosophy. Our approach here will be analytic and speculative.

Abstract

This study is an assessment of knowledge and practice of ethical consideration for literacy in research among graduate students of the two Universities in Cross River State, Nigeria. The first was 214 graduate students’ who had defended proposals, while the second was 120 post field Theses. The two samples were selected through accidental technique from a population of 713 graduate students of the University of Calabar and the Cross River University of Technology who have at least defended their Thesis proposals. Results of the study indicate that only 47.31% of the students knew what ethical consideration meant in research with 83.52% of them emphasising confidentiality in their instruments. Only 33.86% and 26.17% emphasised voluntary participation and anonymity respectively. The study recommends the inclusion of ethical issues in university course outlines for research methods in education.

Abstract

Drug use has not been the problem but rather its abuse and irrespective of the risk thereof, people still abuse them. That is why this study was set out to examine the perceptions of drug use and abuse among adults in Enugu-Ezike in Igbo-Eze North Local Government Area, Enugu State, Nigeria. The study utilized a cross-sectional survey design. The study subjects consisted of 195 respondents (107 males and 88 females) aged 18 years and above. The quantitative data gathered were analyzed with Statistical Package for the Social Sciences (SPSS) using percentages and frequency distribution tables. Chi-square (X2) statistics were used to test the hypotheses The findings showed that 52.3% of the respondents know the meaning of drug use while majority of the respondents were aware of drug abuse. 81.0% of the respondents have negative perception of drug abuse. Also, 54.9% stated that Marijuana is the most abused drug in the study area. Eighty percent (80%) believed that increase in drug abuse increases the rate of crime in the communities. Above thirty-one percent believe that family problems contributed in abusing drugs. The implications of the study to social work practice therefore, is to carry out the public enlightenment, community education, counselling and research on the dangers of drug abuse in Nigeria. The study recommends that the stakeholders in drug use and management should develop appropriate measures to combat the menace of drug abuse that is ravaging our society.

Abstract

There is a tripartite global crises of social, economic and health unlike any in the past almost eight decades history of the United Nations that is fast killing people, increasing and spreading human woes and sufferings with an unending existential calamities. This is indeed, beyond health, economic and social crises. It is evidently human existential crises that have the potency and potential to bring about existential eclipse of the human race. The coronavirus disease (COVID-19) is wreaking havoc on societies at their core. With the International Monetary Fund (IMF) reassessment of the prospect for growth for 2020 and 2021, and the declaration that there is a global recession that is as bad as or even worse than the 2009 situation, Nigeria socio-economic survival is at risk. The only hope of any recovery in 2021 is if the country succeeds in containing the pandemic and take sound and necessary economic decisions and measures. The only roadmap for the socio-economic survival of the country will depend on the proactive management approaches, health policy framework and leadership that will comprehensively address the several social conditions that have to do with health education and literacy level, both nationally and internationally in the areas of economic stimulus that will demand both government and citizens partnerships and the constitution of National Technical Committee on Coronavirus (NTCC) that will relate with a global technical body. The efficient execution of these policy and ideas will certainly demand the total cooperation of all strata of the society, which will include governmental agencies, information experts, civil societies, health experts, educationists and the citizens. What the paper therefore advocates is a multi-disciplinary and interdisciplinary approaches anchored on a sound philosophy through the educational process towards overcoming this 21st century invisible monster. Our approach in this paper will be a combination of analysis and philosophical evidential speculation, which will inspire creativity that will match the novel nature of the crisis.

Abstract

The goal for this research is to build a framework for analysis of technological spillover effect between sectors in Lithuanian manufacturing industry and assess whether predictors of the created model closely follow dynamic fluctuations of technological progress assessed values. Analysis of academic literature suggested using Granger causality test and vector autoregression (VAR) model to analyze intersectoral technological progress spillover effect in any manufacturing industry. Granger causality test can suggest a potential relationship between technological progress values of particular sectors in manufacturing industry while VAR model can define the exact form and extent of spillover effect. VAR models identify presence of intersectoral technological spillover effect in case of 15 out of 18 sectors in Lithuanian manufacturing industry. In case of a few sectors error terms of VAR models are not stationary suggesting that additional exogenous variables need to be included to increase accuracy of estimated coefficients before these models can be used in further analysis. After minor changes presented VAR models can be used for sensitivity analysis analyzing how changes in different sectoral level parameters affect economic development of manufacturing industry as a whole.

Abstract

Coronavirus disease (COVID-19) has spread from China to the world since December 2019. In addition to being a pandemic with mortality risk, COVID-19 affected global mental health. This study is the first to address the mental health aspects among Saudi pharmacy students during this pandemic and to explore the potential effect on their academic development. An online cross-sectional survey was distributed among 677 students from the Faculty of Pharmacy at King Abdulaziz University, Jeddah, Saudi Arabia. Participants were assessed with demographic information, the validated Generalized Anxiety Disorder 7-item (GAD-7) scale, the validated Patient Health Questionnaire-2 (PHQ-2), and multiple stress factors and motivators that might influence their academic development. Collected data were statistically analyzed. Results demonstrated that 32% of the participants were experiencing mild anxiety, 22% moderate anxiety, and 19% severe anxiety. Statistical significance in anxiety level was seen in students living alone, previously diagnosed with mental illness, and within their 4th pharmacy academic year. 49.5% of the participants were PHQ-2 positive and maybe showing symptoms of depressions. Major academic stressor for students with anxiety was their grades while major academic motivator was the coordination of each course studied. Over 70% of pharmacy students had anxiety, and half of them were PHQ-2 positive. We recommend universities to address all students’ psychological needs more often in the future, especially during a crisis like this pandemic and look into the possibility of having a Pass/Fail outcome rather than a grade-based GPA.

Abstract

The research aims to explore the determinant of firm’s market-based performance in Indonesia manufacturing companies, listed in Indonesia Stock Exchange between 2014 to 2019. The proxies used in this research are Return on Equity (ROE), Leverage, Earning per Share (EPS), Growth, Liquidity (Liquid) and Non-Debt Tax Shield (NDTS). The sampling method employs purposive sampling while the analysis is performed using E-views version 11. The result indicates that in partial, Leverage is negatively significant affect to Firm Performance while the other measured variables, namely Return on Equity, Leverage, Earning Per Share, Liquidity and Non-Debt Tax Shield, prove to be insignificant affect to firm performance. All variables simultaneously affect strongly on Firm Performance. This research implies that the management of the firm should observe Return on Equity (ROE), Leverage, Earning- per Share (EPS), Growth, Liquidity (Liquid) and Non-Debt Tax Shield (NDTS) closely in developing their strategy for better firm performance.
