The study aims to look at the relationship between environmental quality and financial instability in Nigerian over the period of 1970 to 2019 respectively. The Autoregressive Distributed Lag (ARDL) model is used in estimating the short-run as well as the long-run relationship between financial instability and the quality of the environment. The results of the study reveal that financial instability has a significant and positive impact on CO2 emissions, implying that financial instability is lowering the quality of environment in Nigeria. In addition, consistency and strength are verified by the application of numerous tests of diagnostic. The research introduces new insights that would not only be of benefit in advancing prevailing research but may also be of specific concern to policymakers in the financial sector of the country and its starring role in enhancing the quality of the environment. The results recommend that to prevent financial instability and its effect on environmental degradation in the light of policy consequences, financial sector reforms should be implemented with great caution. Contribution/ Originality
This study contributes to the existing literature as the first research considering Nigeria that establishes the Aggregate Financial Stability Index (AFSI) to investigate the relationship between financial stability and environmental quality. The AFSI is made up of sub-indices that measure the development, vulnerability, and soundness of the financial sector.

Local Governments and the Conundrum of Service Delivery in Nigeria: What Policy Implications?
Research Article
Author(s):
Journal: International Journal of Public Policy and Administration Research
Local governments, the world over, in a bid to fulfil their role in delivering essential goods and services, are faced with enormous challenges and contend with allocating resources to meet up with increasing demands for public service. Adopting a multistage sampling method, the study sampled 400 respondents selected from 3 Local Council development Areas [LCDAs] covering 10 communities in Ikeja Local Government Area of Lagos State, Nigeria. Findings from the study indicated that lack of autonomy, corruption, and poor planning are the major challenges confronting local governments in service delivery in Nigeria. It also concludes that the challenges of service delivery by local governments are not restricted to rural areas alone, rather, local governments in urban areas suffer the same fate. The study, therefore, made policy recommendations which include the setting up of a Community Education System (CES) to sensitize the local government residents on the role of local governments in service delivery; setting up of Community Feedback Monitoring System (CFMS) to promote transparency, accountability and probity and the formation of Community Anti-Corruption Volunteers’ Group (CACVG) for campaigning against corruption at the local government level. Contribution/ Originality
This study contributes to the existing literature on local government administration and service delivery in Nigeria using primary data from an urban area. It proffers practicable solutions to the conundrum through the setting up of: Community Education System (CES); Community Feedback Monitoring System (CFMS); and Community Anti-Corruption Volunteers’ Group (CACVG).

Current Trends and Realities of International Students in East and Southeast Asia: The Cases of China, Hong Kong, Taiwan, and Malaysia
Research Article
Author(s):
Journal: International Journal of Education and Practice
By reviewing regulative documents and extant literature, this paper explores the realities and trends of international students in East and Southeast Asia (ESA). It also shows motivation and strategies of four new players in the international higher education sector in East and Southeast Asia i.e., China, Hong Kong, Taiwan and Malaysia. Apart from showing that intraregional students have not predominated the overall international student population in the region anymore, the paper highlights that ESA region has become an established hub of international students rather than a new emerging destination as it was in previous years. The overall net flow of international students in this region was still deficit prior to 2010s, but the deficit in 2017 is still less than that of 2010’s. This is probably the first study of its kind to examine the trends of international students as well as of higher education policies of countries in the ESA region. The findings of this study shall provide an insight into international higher education trends among the ESA countries for stakeholders, including policymakers, university managers, faculty, students, and parents. Contribution/ Originality

The Relationship among Body Composition, Exercise Participation, and Perception towards a Lifetime Fitness Class in College Students
The current study analyzed the relationship between body composition and exercise participation, along with perception toward lifetime fitness (LF) classes in college students. Thirty-eight college students (20 males and 18 females) in a regional university completed a survey pertaining an LF class and exercise participation. Additionally, height, weight, waist-to-hip ratio, and body composition [fat free mass (FFM), fat mass (FM), and body fat percentage (BF%)] were assessed. Most males (65%) and females (77%) reported personal wellbeing as their main motivation to exercise (p = 0.021) outside of their LF class, rather than it being driven by a personal achievement motivation (35% males and 23% females). Males who exercise less than twice a week were associated with having lower FFM (p = 0.041), whereas females who exercise less than twice a week were associated with lower body mass index (p = 0.004), FFM (p = 0.027), and FM (p = 0.001). Although personal wellbeing was the main motivation to exercise for both male and female students, each sex has shown unique trends in its desires to participate in an LF class. Therefore, future LF classes should consider adopting curriculums that are able to uphold personal wellbeing motivation and account for unique needs and goals males and females may have in order to promote LF class engagement. Contribution/ Originality
This study documents the importance of remodeling the curriculum for college fitness classes based on personal wellbeing motivation and sex-specific goals to promote engagement for reasons other than it being required and to reap the necessary benefits of regular exercise.

External Debt Dynamics and Sustainable Growth in Nigeria
Research Article
Author(s):
Journal: International Journal of Sustainable Development & World Policy
The paper provides empirical insights about how the interactions between the external debt and external sector dynamics impacts on economic growth in Nigeria. The paper underscored the critical desire to understand how debt-growth relationship could be optimized for sustainable economic development and growth in developing countries. It proposes modelling the external sector and debt dynamics in order to attain sustainable development in Nigeria. This study became imperative because Nigeria occupies a very significant position in Africa. Nigeria, though a developing country, is currently the largest black nation in the world and most populous country in Africa. The paper opted for an ex post facto research design using CBN statistics extrapolated from its statistical bulletin with 37year coverage from1980-2016. The data was analyzed using the ARDL and granger causality technique coupled with other pre-estimation and diagnostic tests. The result showed foreign-debt and debt-service was negatively not-significant on sustainable growth. It was concluded that though Nigeria wasn’t wrongly positioned on the debt-laffer-curve, the economy had not benefitted positively from the mass of debt funds accessed. The paper's primary contribution is finding that external debt and debts service had a negative (not-significant) impact on economic growth in Nigeria. The policy implication of this research may be applied to other developing countries. The propositions may however lack general applicability in more advanced economies. Contribution/ Originality
The paper contributes in the literature by providing empirical insights about how the interactions between the external debt and external sector dynamics impacts on economic growth in Nigeria. Economics » International Journal of Sustainable Development & World Policy » Month: 12-2021 Issue: 2
Suitability of Bacteria in Bioremediation Techniques Common for Petroleum-Related Pollutions
Petroleum hydrocarbon is an energy source that drives our modern society and at the same time impacts the environment. The consequences of hydrocarbon pollution range from microbial diversity distortion to cancer scourge in humans. To reverse these negative trends imposed by the contaminated environment, deliberate remediation steps, need to be employed, which depend on physical, chemical, and biological mechanistic principles. The physicochemical approach is quick-oriented but is more expensive relative to the biological option. The latter uses microorganisms, their parts, or enzymes to decontaminate and detoxify hazardous fractions of hydrocarbons into benign products. This biotechnology is referred to as bioremediation. Bioremediation effectiveness is achieved through the implementation of various techniques that are carried out under aerobic or anaerobic conditions or in ex-situ or in-situ. However, the aeration-related condition is the most deciding factor for microbial adaptation and survival. In aerobic conditions, fungi, bacteria, and algae contribute actively in the biotransformation and detoxification process, thus give the best result in such circumstances. However, in an anoxic environment, the prominence of bacteria comes into play (due to their ability to thrive in extreme environments) in degrading the contaminants into less harmful compounds. Thus, bacteria stand the chance of been used as the most resourceful biological tool for petroleum biotechnology including environmental remediation of extreme environments due to their high adaptive index value. Moreover, the hydrocarbon impacted environment is often characterized by high salinity, extreme temperatures, high pressure, and extreme pH. Contribution/ Originality
This review contributes to existing literature by indicating the utility of bacteria in bioremediation techniques. Biological Sciences » The Asia Journal of Applied Microbiology » Month: 06-2021 Issue: 1
The Contributions of Metacognitive Skills towards the Retention of Different Academic Ability Students for the Implementation of Several Learning Models
Research Article
Author(s):
Journal: International Journal of Education and Practice
Metacognitive skills are self-regulation activities required to achieve active learning, critical thinking, problem solving, and decision making. There is a dearth of research on the contribution of metacognitive skills for the retention of students with varying academic abilities. This research study aims to fill this gap by suggesting learning models including READS (Reading, Exploring, Answering Discussing and Summarizing) learning model, Reading, Questioning and Answering (RQA) learning model and Conventional learning models. The sample of the study comprised 206 students divided into two equal groups of 103 students, each of high academic abilities and low academic abilities. The data was collected through a test and a rubric. The results of the regression analysis show that the READS learning model was better able to improve the metacognitive skills and retention of students with lower academic abilities compared to students with upper academic abilities. The results in the RQA learning model and conventional learning models show an increase in metacognitive skills and retention of students with higher academic abilities much faster than in students with low academic abilities. This suggests that the application of the READS learning model is more suitable for students with low academic abilities. The study recommends that teachers should learn to implement effective learning models to improve the metacognitive skills and retention of the upper and lower academic ability students. Contribution/ Originality
This study has endeavored to explore the possibility of designing learning models by enhancing metacognitive skills and retention of students with varying academic abilities. The study premises that students with low academic abilities can compete with students with high academic abilities if given the right learning model.

Assessing the Efficacy of a Character Development Program in Non-Traditional Undergraduate Students
Research Article
Author(s):
Journal: International Journal of Education and Practice
The purpose of this quantitative ex post facto study was to examine if there is a significant difference in mean moral judgment levels of first year undergraduate students after participating in a character development program at a non-traditional program in a university in the southwestern United States. This study included new non-traditional students matriculating between October 2019 and June 2020. The measurement instrument for the study was the Defining Issues Test-2 (DIT-2). Pre- and post-test DIT-2 archival data was retrieved from the study site for the two assessments. The independent variable was the character education program of study, and the dependent variables were the difference in the mean scores from the DIT-2. Paired t-tests were used to determine if a statistical difference existed after character training. The positive mean change in post-conventional thinking scores, P (M = 2.24), N2 (M = 1.70), were not significantly different than zero (P score p = 0.203, N2 score p = 0.203). The positive mean change in scores for the lowest level of moral reasoning, PI, (M = 0.15) was not significantly different from zero (p = 0.912). The predominant moral schema used by the students, maintaining norms (MN) demonstrated a negative mean change (M = -1.35) but it was not significantly different from zero (p = 0.348). Therefore, the character program of study at the site did not increase moral reasoning levels. The results are significant, as they help to define what works and what does not in non-traditional student ethical development. Contribution/ Originality
This study is one of very few studies which have investigated the efficacy of a comprehensive character education program in non-traditional undergraduate students. These research findings may provide insights for institutional leaders looking to develop and evaluate high-impact character and ethics programming.

Author(s):
Journal: International Journal of Business, Economics and Management
Relational Capabilities (RC) appear are valuable capabilities not only for performance but also to generate profitability. In this vein, this study performed a meta-analytic investigation of RC dimensions influencing firm financial performance. It also examined the role of mediating and moderating effects of knowledge management and partners integration influencing this association. From a meta-analytic procedure, 54 empirical studies were examined through random-effects model of Pearson’s correlations as the effect size and a meta-analytical regression analysis (MARA) to examined moderation effects and meta-analytical structure equation modeling (MASEM) to examined mediation effects. Our findings confirm that firm financial performance is impacted directly and positively by RC itself excepting by the intrafirm relational capacity dimension. We also find that knowledge management and partner integration do not mediate positively the effect RC on firm financial performance. Further, RC dimensions effects on firm financial performance vary positively and negatively across partner integration and knowledge management moderation effects. Contribution/ Originality
This study challenges RC into firms’ business ecosystem as one of their sources of growth to create several opportunities. Therefore, by indicating a potential evolution of this dynamic capability in a more financial favorable comprehension, this article contributes to society, economy in general and to the science of business management.

Research Article
Author(s):
Journal: Current Research in Agricultural Sciences
Soil chemical properties plays a crucial role in crop yield. In this study, we evaluated the chemical properties of soils under three different cropping systems practiced for more than five years in Changunarayan municipality of Bhaktapur district of Nepal. The cropping systems includes- (i) cultivation inside polyhouse (Treatment A: polyhouse), (ii) paddy-wheat rotation (Treatment B: P-W), and (iii) paddy-wheat-vegetable rotation (Treatment C: P-W-V). Thirty-nine composite samples (13 replicates from each site) were taken from the area based on variation in landforms. Soil pH, organic matter (%), total nitrogen (%), available phosphorus (mgkg-1), and available potassium (mgkg-1) were evaluated for each sample. The study revealed that the soil pH was acidic and ranges between 4.71 and 5.39, organic matter (1.6-2.39%), total nitrogen (0.091-0.13%), phosphorus (4.48-29.24mg kg-1) and potassium (88.04-109.52 mg kg-1). A significant lower mean pH (4.71), and higher mean organic matter (2.39%), total nitrogen (0.13%) and available phosphorus (29.24 mgkg-1) were observed in cultivation under polyhouse. Incorporation of vegetable in paddy-wheat system gave significant (p<0.05) higher accumulation of soil phosphorus and consistently raised other nutrient status. Moreover, cultivation under polyhouse raised C:N ratio (10.55) significantly than other system. This finding can be relevant to wide range of readers that focus on soil chemical properties and can be used in developing future research strategy and sustainable soil management system in the area. Contribution/ Originality
In this paper we analyzed the impact of different cropping system over soil quality. Agricultural Sciences » Current Research in Agricultural Sciences » Month: 12-2021 Issue: 2
Trade Credit and Performance of Food Production Companies in Vietnam
Research Article
Author(s):
Journal: International Journal of Management and Sustainability
Trade credit (TR) plays an important role in financial structure and impacts on company performance. The issues related to TR have long been researched, with the first studies conducted by Nadiri (1969); Schwartz (1974); Lewellen, McConnell, and Scott (1980); Ferris (1981); Emery (1984). This study applies panel regression models, such as Pooled OLS, Fixed Effects, Random Effects, and FGLS, to evaluate the impact of TR on the performance of Food Production Companies in Vietnam. Company performance is measured by the Data Envelopment Analysis model (DEA). In addition, the Bayesian analysis method is used to test the robustness of the estimators from the models evaluating the effect of TR on company performance. Using annual data from the financial statements of 35 Vietnamese Food Production companies in the period 2008-2020, provided by Thomson Reuters, the results reveal a non-linear relationship between TR and company performance with an inverted U shape. Specifically, when TR, or accounts receivable on total assets, increases, company performance will also increase. However, when the increase in accounts receivable on total assets exceeds a certain limit, company performance will decrease. Based on the results, some policy implications are suggested to manage the accounts receivables effectively in Vietnamese Food Production Companies. Contribution/ Originality
This study contributes to the existing literature by analyzing the nonlinear effects of TR on company performance. Further, this study uses the Bayesian inference method instead of the frequency inference method to assess influencing factors.

Is Working from Home Good for Work-Life Balance, Stress, and Productivity, or does it Cause Problems?
This study aims to investigate the impact of employee productivity while working from home for a long period due to the COVID-19 pandemic quantitatively from the aspects of work-life balance, and employee stress levels. Several previous studies have explained that working from home (WFH) is known to contribute positively to work productivity. However, in contrast, several other studies have shown that working from home harms employee productivity. This research was conducted in Jakarta, Indonesia. The study sample comprised 135 employees who worked from home and the analysis was carried out using LISREL 8.5. The results of this study indicate that work-life balance and work-related stress affect work productivity. Meanwhile, working from home does not affect work productivity. The findings of this study show surprising results and can influence changes in organizational policies and strategies for collaborating between working from home and working from an office for employees. Contribution/ Originality
This study contributes to the existing literature related to work from home policies during the COVID-19 pandemic. This research has never been carried out by previous research regarding the impact of work from home on work-life balance, stress, and work productivity during the COVID-19 pandemic.

Earnings Quality and Audit Quality: Analysis of Investor Reaction
This study aims to analyze investor reaction to management behavior in preparing financial reports, especially earnings quality and audit quality. We also analyze the effect of financial performance as moderation. Generally, investors react positively to a company's financial performance, but the amount of fraud surrounding financial information, including auditor cooperation, raises big questions for investors about a company's financial information. We analyzed companies within the manufacturing sector that were listed on the Indonesia Stock Exchange from 2015 to 2019, and it was found that investors reacted positively to earnings quality and audit quality moderated by financial performance. These results provide evidence that management should focus on earnings quality in financial reports and on the audit process to ensure quality and exceptional financial performance to obtain positive reactions from investors, which has a positive impact on increasing the value of companies’ shares. This study used the stock prices on the publication date of the financial statements, which reflect the direct reactions of investors to the information contained in the financial statements, such as earnings quality, audit quality, and financial performance. The different investor reactions were apparent on the day of the deadline for submitting financial statements according to existing regulations. These results reflect that the use of stock prices on the publication dates more accurately describes the reaction of investors than on the deadline for submitting financial statements. Contribution/ Originality
This study contributes to existing literature by investigating investor reaction to management behavior in preparing financial reports, especially earnings quality and audit quality. Social Sciences » Humanities and Social Sciences Letters » Month: 09-2021 Issue: 3

Climate Change Effect on Irrigation Water Requirement of Wheat and Maize in Northern Part of Bangladesh
Research Article
Author(s):
Journal: International Journal of Climate Research
Bangladesh is one of the most vulnerable countries for climate change in agricultural water management. A research had been done to assess climate change effects on irrigation water use of wheat and maize in the northern part of Bangladesh. The twenty nine years of data (1990-2018) were analyzed with Mann-Kendall test as well as Sen’s slope for climate change impact and the responsible weather parameters due to climate change were identified with correlation coefficients. The crop water requirement of wheat in Bogura and Rangpur was declining at the rate of 3.3mm and 2.3mm per decade respectively. Net irrigation water requirement of wheat at both Bogura and Rangpur was inclining at the rate of 1mm and 10mm per decade respectively because the effective rainfall of these regions was decreasing at 5mm and 11mm per decade respectively. The crop water requirement of maize for similar districts was increasing at the rate of 3.2mm and 2.5mm per decade respectively although net irrigation water requirement had statistically non-significance for climate change effect. The weather parameter, which was mainly responsible for climatic change in irrigation water requirement, was increasing temperature. Therefore, wheat cultivation might be coped with climate change in the northern part of Bangladesh rather than maize on the basis of irrigation and water management. Contribution/ Originality
The paper's primary contribution is finding that the northern region of Bangladesh might be meet up extra irrigation water demand for wheat and maize cultivation due to climate change. Energy & Environmental Sciences » International Journal of Climate Research » Month: 06-2021 Issue: 1
Developing a Software Application for the Study and Learning of Linear a Script
The link between the scripts of many ancient languages and technology is minimum and occasionally superficial. As a result, their study and analysis remain a challenge for the researchers. Such an example of ancient script is Linear A, which is still considered the very first European script. Nowadays, there has been three main languages or language families of origin suggested, spoken in the Bronze Age, in order to attempt the decipherment of Linear A texts: (a) a language of the Aegean Sea, (b) certain languages of the Western Anatolia family and c) an Akkadian dialect. Therefore, there is a strong possibility that Linear A may render occasionally more than one language. The present survey initiates the adaptation of an existing computational framework for the interpretation and learning of syllabic scripts, already tested in Linear B script, to facilitate the research regarding the underlying language(s) of Linear A. Linear B have many signs in common with Linear A and of a known phonetic value per sign. Therefore, it is most appropriate for facilitating the study and potential decipherment of Linear A. This paper presents an outline of the designed software application, along with the sources that are studied and used for the adaptation of the existing computational framework for Linear B. Contribution/ Originality
This study is one of very few studies which have investigated the possibility of deciphering and simultaneously learning an ancient script of the Bronze Age, namely Linear A, by developing an interactive software application for this purpose that includes a multilingual database.

A security detection system was developed to secure any of the walls that were crossed. These walls are the north, east, south and, west wall. These walls are designed to be in a square environment, each of these walls has a Light Emitting Diode (LED) that functions as a transmitter and a Light Dependent Resistor (LDR) that function as a Receiver. A closed-circuit television (CCTV) was used to capture the real-time video of any of the crossed walls. A Liquid Crystal Display (LCD) was used to display the status of these walls and display the name of the crossed walls. A magnetic buzzer is also used to alert the security personnel after a system has displayed the name of the crossed wall on the LCD. A Microcontroller (PIC16F877A) is used as the brain of the developed security system. The Personal Computer (PC) is also used to display the system status through personal computer Parallel Port, to display the real-time video captured by the CCTV camera, saving the video on personal computer hard drive, and to control the developed system from the personal computer (PC) such as activating, deactivating and resetting the developed system. With the aid of the latest development in technology nowadays, it is possible to secure the properties and people’s lives using a security detection system that will monitor, guide, and protect the environments that need to be secure against burglars and abductors. Contribution/ Originality
It is to create awareness of the security alarm system and to prevent intrusion and abduction. Computer Sciences » Review of Computer Engineering Research » Month: 06-2021 Issue: 1
Twin Deficit Hypothesis and Macroeconomic Fundamentals: New Evidence from Nigeria
Research Article
Author(s):
Journal: Quarterly Journal of Econometrics Research
This study tests for the validity of the twin-deficit hypothesis in Nigeria for the period 1981 – 2018 and further seeks to ascertain the role of macroeconomic fundamentals in driving this hypothesis using the non-linear autoregressive distributed lag (NARDL) model and structural vector autoregressive (SVAR) model. With evidence from granger causality test, the results obtained for the NARDL model support the validation of the twin-deficit hypothesis for the Nigerian economy. As long-run equilibrium exists, it was further established that the twin deficits were majorly driven by the degrees of financial and trade openness in Nigeria as no substantial shock effects of the twin deficits were traceable to any of the macroeconomic fundamentals. It is therefore recommended that policy makers in Nigeria should properly sequence the degree of economic openness to ensure the overall health of the economy. Contribution/ Originality
The study employs the novel technique of non-linear autoregressive distributed lag (NARDL) to investigate the asymmetric relationship between fiscal and current account deficits. More so, the study distinguishes between budget deficit and fiscal deficit in estimations through the inclusion of borrowing, as a significant component of fiscal deficit in Nigeria.
