Geospatial Assessment of Groundwater Potential in Jos South Local Government Area of Plateau State, Nigeria

Groundwater occurrence in the Jos-Bukuru Younger Granite Complex of Jos South LGA. is regulated by permeabilities of the crystalline basement complex induced through weathering processes in which aquifers are usually discontinuous and could worsen the issue of water scarcity in addition to an improper sighting of water wells. This study identified the features for determining groundwater potential zones, examine the spatial pattern and relationship between the results obtained from geospatial and geophysical techniques. The study used geospatial techniques to construct and integrate thematic maps based on multi-criteria assessment using Saaty's Analytical Hierarchy method, and geophysical techniques such as Vertical Electrical Sounding (VES) using electrical resistivity method. The findings revealed very high groundwater potential in the northern part of the area characterized by high rainfall, low slope and dominated by cambisols with high relative water retention capacity. Also, moderate to low groundwater potential areas are scattered all over the study area, while the very low is found within the central areas. However, geophysical results overlaid on groundwater potential map coincides with the expected values. Areas with higher value of aquifer thickness such as Vom, Bukuru, and Barakin Columbai have high groundwater potential and areas with low aquifer thickness such as Dutsen Kato, Gyel and Du have low groundwater potential. Generally, from this study, it can be deduced that geospatial techniques such as Remote Sensing and GIS are faster, cost-effective and accurate in assessing groundwater potential zones. This study suggests that the government, decision-makers, and stakeholders in water resources should consider deploying geospatial techniques when conducting groundwater exploration.
Plankton food webs in the oligotrophic Gulf of Mexico spawning grounds of Atlantic bluefin tuna

Abstract We used linear inverse ecosystem modeling techniques to assimilate data from extensive Lagrangian field experiments into a mass-balance constrained food web for the Gulf of Mexico open-ocean ecosystem. This region is highly oligotrophic, yet Atlantic bluefin tuna (ABT) travel long distances from feeding grounds in the North Atlantic to spawn there. Our results show extensive nutrient regeneration fueling primary productivity (mostly by cyanobacteria and other picophytoplankton) in the upper euphotic zone. The food web is dominated by the microbial loop (>70% of net primary productivity is respired by heterotrophic bacteria and protists that feed on them). By contrast, herbivorous food web pathways from phytoplankton to metazoan zooplankton process <10% of the net primary production in the mixed layer. Nevertheless, ABT larvae feed preferentially on podonid cladocerans and other suspension-feeding zooplankton, which in turn derive much of their nutrition from nano- and micro-phytoplankton (mixotrophic flagellates, and to a lesser extent, diatoms). This allows ABT larvae to maintain a comparatively low trophic level (~4.2 for preflexion and postflexion larvae), which increases trophic transfer from phytoplankton to larval fish.
Trading support method based on computational intelligence for speculators in the options market

The financial world has changed dramatically in recent decades. Electronic data processing, globalisation, and deregulation have changed markets, and the biggest part of these major changes includes derivatives. As financial markets become more interconnected and global, volatility in these markets may increase dramatically in the future. It is natural that the derivatives market is gaining attention and popularity among market participants as an alternative to traditional investment and speculative instruments. The growing number of technologydriven applications and innovations in the financial sector encourages the inclusion of products relating to automated trading and robotic advice in financial decision-making. The aim of this paper is to investigate different option-trading strategies and to evaluate the effect of computational intelligence on trading success in the derivatives markets. The recurrent neural network (RNN) Keras was adopted for forecasting option prices, and the results were compared with the forecasting using the evolution of recurrent systems with optimal linear output algorithms (EVOLINO) for RNNs. This forecasting Received: January, 2020 1st Revision: July, 2020 Accepted: September, 2020 DOI: 10.14254/20718330.2020/13-3/15 Journal of International Studies S ci en ti fi c P a pe rs © Foundation of International Studies, 2020 © CSR, 2020 Journal of International Studies Vol.13, No.3, 2020 232 tool was investigated as a support system for speculators in the options market. The proposed method helps speculators select an appropriate option-trading strategy and increases the probability of profit. The values of trading according to the information from the tools of computational intelligence proved that the proposed method is useful, although trading in options is still very risky.
xtoaxaca - Extending the Kitagawa-Oaxaca-Blinder Decomposition Approach to Panel Data

The Kitagawa–Oaxaca–Blinder decomposition approach has been widely used to attribute group-level differences in an outcome to differences in endowment, coefficients, and their interactions. The method has been implemented for Stata in the popular oaxaca command for cross-sectional analyses. In recent decades, however, research questions have been more often focused on the decomposition of group-based differences in change over time, for example, diverging income trajectories, as well as decomposition of change in differences between groups, for example, change in the gender pay gap over time. We review five existing methods for the decomposition of changes in group means and contribute an extension that takes an interventionist perspective suitable for applications with a clear before–after comparison. These decompositions of levels and changes over time can be implemented using the xtoaxaca command, which works as a postestimation command for different regression commands in Stata. It is built to maximize flexibility in modeling and implements all decomposition techniques presented in this article.
Determinants of Work-from-Home Productivity among Higher Education Institution Employees during the Covid-19 Pandemic in Malaysia

This study focuses on evaluating direct relationships between workplace environment, peer support, employee motivation and organisational support, and employee productivity support within higher education institutions in Malaysia during the Covid-19 pandemic. The Structural Equation Model technique was utilised to assess the direct effects of workplace environment at home, peer support, employee motivation, and organisational support on employee productivity. The model was designed and later analysed using the Partial Least Square procedure on data collected from a survey that yielded 579 usable questionnaires. The results demonstrated that workplace environment, peer support, and employee motivation have a positive and significant influence on employee productivity, while organisational support has a negative and significant influence on employee productivity. The findings suggest that higher education institutions should give greater emphasis on strengthening the workplace environment at home, peer support, employee motivation, and organisational support to ensure employee productivity is high if a work-from-home policy is implemented.
"I Understand, Honey": Perceived Spousal Empathy's Moderating Influence on the Links Between Depression and Marital Satisfaction and Marital Satisfaction and Physical Health

I Understand, Honey”: Perceived Spousal Empathy’s Moderating Influence on the Links Between Depression and Marital Satisfaction and Marital Satisfaction and Physical Health Francisco Javier Celestino School of Family Life, Brigham Young University Master of Science An adapted version of the Vulnerability-Stress-Adaptation model was used as a theoretical guide for this study, which proposes that adaptive processes exist and can moderate relationships between enduring vulnerabilities and different outcomes. Relationships of interest include the negative link between depression and marital satisfaction and the positive link between marital satisfaction and physical health. An adaptive process of interest is empathy, due to its wellresearched positive impact on mental, relational, and physical health. This study examined whether perceived spousal empathy (i.e., the empathy perceived by one spouse coming from their spouse) had any moderating effects on the previously mentioned links. A clinical sample of 34 relationally distressed heterosexual couples was included in the study. Depression unexpectedly had a positive relationship with marital satisfaction and physical health. Marital satisfaction had no significant relationship with physical health. Perceived spousal empathy had no moderating effects. The clinical implications of the results are discussed.
A Tale of Two Hearts: Cardiac Manifestations of Coronavirus-2019. A Case Series and Literature Review

Coronavirus disease 2019 (COVID-19) originally emerged as respiratory disease from a novel coronavirus, SARSCoV-2. While initial cases revealed a spectrum of respiratory-associated clinical presentations ranging from mild shortness of breath with associated cough to severe respiratory distress, extrapulmonary symptoms, with or without concomitant respiratory disease, have been increasingly reported. Cardiovascular complications are noted in a subset of patients with presentations ranging from non-ST elevation myocardial infarction to fulminant myopericarditis. While cardiac myocytes express the SARS-CoV-2 receptor, Angiotensin converting enzyme 2 (ACE2), the mechanism of cardiac effects remains unknown, further underscoring the complex nature of COVID-19. Here we report two cases of COVID-19 in which cardiac manifestations – pericarditis with associated pericardial effusion and tamponade physiology and fulminant myocarditis – were the predominant manifestation of COVID-19. We hypothesize that many of COVID-19 pulmonary and extra-pulmonary manifestations manifest not only from direct SARS-CoV-2 toxicity in select tissues, but also its interaction with a complex interplay of host factors including genetic and epigenetic modifications of crucial genes – Angiotensin Converting Enzyme 2, Angiotensin Converting Enzyme 1, and Transmembrane protease serine-2 – and their respective affiliation with multiple signaling cascades with resultant dysregulated proinflammatory effects.

The aim of this paper is to check how users expressions matche subject headings and to prove jf knowledge structure used in online catalogs enhances searching effectiveness. A bibliographic revision about difficulties in subject access and proposed methods to improve it is also presented. For the empirical analysis, transaction logs from two university libraries, online catalogs (CISNE and FAMA) were collected. Results show that more than a quarter of user queries are effective due to an alphabetical subject index approach and browsing through hypertextuallinks.
Convergence results for proper splittings

Given anm× n linear system Ax = b (1) If A = M −N is a proper splitting, the iteration x = M †Nx(k) +M †b, k = 0, 1, 2 . (2) converges to the best least squares solution A†b if, and only if, ρ(M †N) < 1. We extend some convergence results of Berman and Plemmons (1974) for the iterative scheme (2) establishing analogous convergence conditions for splititngs of nonsingular matrices introduced by Climent and Perea (1998). Key-words: proper splitting, iterative process, Moore-Penrose inverse, cone, nonnegative matrix, nonnegative splitting.
The Effect of Depression, Anxiety, and Stress on Heart Rate Variability During Self-Critical and Self-Compassionate Exercises

The Effect of Depression, Anxiety, and Stress on Heart Rate Variability During Self-Critical and Self-Compassionate Exercises Derek C. Bartlett Department of Psychology, Brigham Young University Master of Science The cognitions of individuals who experience symptoms of depression, anxiety, and stress have been well documented, but their physiological reactions have not. The present study examines the physiological reactions of individuals with elevated levels of depression, anxiety, and stress during a self-critical and self-compassionate writing exercise to see if there is a difference in comparison to healthy participants. This study is a secondary analysis of data that was collected from a randomized controlled trial where participants followed a protocol. This protocol consisted of a 5-minute baseline, a 10-minute breathing exercise or nature video, 5minutes of a self-critical writing exercise, 5-minutes of a self-compassionate writing exercise, and a 10-minute recovery period. The individuals in the study were separated into different groups depending on their scores on a measure of depression, anxiety, and stress. The data were analyzed twice with two different grouping methods. One method compared individuals with mild to severe symptoms of depression (n = 35), anxiety (n = 43), and stress (n = 33) to healthy group (n = 26) and another method compared individuals with moderate to severe symptoms of depression (n = 28), anxiety (n = 36), and stress (n = 24) to 44 healthy individuals. In both methods, the participants with symptoms of depression, anxiety, and stress did not significantly differ from healthy participants on any measure of HRV. Overall, the results of this show that college students with symptoms of depression, anxiety, and stress physiologically react in a similar way to a self-critical and self-compassionate writing exercise.
The Two Bengals: Female Laborforce Participation in West Bengal and Bangladesh

Till the British granted independence to India and Pakistan in 1947, the area that now covers West Bengal and Bangladesh was part of the larger Bengal presidency under colonial rule. The war of 1971 saw East Pakistan gain independence from Pakistan and embark on a new political journey as the country now known as Bangladesh. Both West Bengal and Bangladesh have undergone rapid changes, both economic and political over the last 68 years but retain a shared culture, history and topography. Despite these commonalities, both regions exhibit very different levels of socio-economic development, one of which is the wide disparity in female labor force participation. Rapid development in garment manufacturing since the 1990s and more recently, community and health service, has driven young women to join the labor force in large numbers in Bangladesh. On the other hand LFPR for women remains abysmally low in West Bengal and is among the lowest across all major Indian states.
Synthesis and Characterization of Silver Nanoparticles Using Prodigiosin Pigment and Evaluation of Their Antibacterial and Anti-Inflammatory Activities

This study focused on the biological synthesis of silver nanoparticles (AgNPs), using prodigiosin pigment produced by Serratia marcescens. The effect of parameters such as pH, temperature, time, with various concentrations of silver nitrate (AgNO3) and prodigiosin on the synthesis of AgNPs were also studied. Optimized results of the biosynthesis process revealed an increase in the intensity of Surface Plasmon Resonance (SPR) bands of nanoparticles with shifting at the wavelength of 400 nm. In addition, optimum synthesis of AgNPs was achieved at pH 12, temperature 55°C, and reaction time 24 h, with concentrations of prodigiosin, as a reducing agent, of 12.5 μg/ml and silver ion concentration of 1 mM. Measurement of the size of silver nanoparticles by SEM diffraction revealed a value of 30 nm. Finally, the minimum inhibitory concentration of AgNPs against pathogenic bacteria was 32 μg/ml for Staphylococcus aureus and Pseudomonas aeruginosa. The results of anti-inflammatory effects of Ag NPs obviously demonstrated that the infections of test animals treated with AgNPs were completely healed after 4 days of treatment, while the animals treated with fucidin (as control) did not exhibit any healing.
Research on reaction mechanism of nitrogen in O_2/CO_2

The experiment sends gases mixture, which includes CH_4、O_2、CO_2、Ar、NO、NH_3, and coal into one dimension drop-tube furnace to simulate coal combustion in O_2/CO_2. The effect of fuel nitrogen recycled NO concentration and their interactions on NO emission are discussed respectively. The experiment result shows in reducing mood the homogeneous reaction between NH_3, HCN, CH_4, CO and recycled NO are major factors that can decrease NO emission when coal combusts in O_2/CO_2. And the heterogeneous reaction and adsorption reaction of carbon and NO have a better effect than in oxidization atmosphere. With the concentration of CO_2 increasing, oxidization ratio of fuel nitrogen increase but the reduction ratio of recycled NO decrease in oxidization atmosphere and increase in reducing atmosphere. When concentration of CO_2 keeps at a constant, the effect of NO deoxidization increase with the concentration of recycled NO increasing. When concentration of recycled NO keeps at a constant, with the excess air ratio increasing, low concentration of CO_2 is more favorable for NO deoxidization, but high concentration of CO_2 has negative effect on NO deoxidization.
EFFECTS OF DROUGHT STRESS AND POTASSIUM ON THE GROWTH AND YIELD OF LOCALLY PLANTED SWEET CORN

Drought stress is an abiotic factor affecting growth and yields of crop plants globally. The growth and yield performances of Thai Super Sweet (TSS) corn variety treated with drought stress levels (29.00%, 14.50% and 7.25% Soil Moisture Content, SMC) and potassium rates (30, 60 and 90 kg/ha) were investigated in an insect-proof net-house of Faculty of Sustainable Agriculture (FSA), Universiti Malaysia Sabah, Sandakan Campus, Malaysia. Drought treatment was applied at the flowering stage (period of tasseling to complete silk emergence) and lasted for 20 days. Experimental units were arranged factorial completely randomized design with four replications. Parameters of growth, chlorophyll content, proline content and yield were measured and analysed statistically in this study. Plant height, first cob height from the soil surface, fresh cob weight, grain number per cob, 100-grain weight and free proline content showed interaction effects among the drought and potassium treatments while cob length showed significant effect among drought stress treatments and relative chlorophyll content showed significant effect among potassium rates treatments. It may be concluded that 7.25% SMC + 60 kg/ha K was adequate for irrigation and fertilization for the corn plants as there was no significant difference observed when compared to the control treatment, 29.00% SMC + 60 kg/ha K. Corn plants treated with 7.25% SMC + 60 kg/ha K expressed tolerance response through the higher level of proline content which aid in resisting drought stress and hence was able to perform the best overall yield components. The irrigation cost that can be saved is RM722.90 per hectare with 7.25% SMC. Thus, irrigation reduced to 7.25% SMC can be recommended to the farmer to reduce the cost of irrigation and hence to obtain a better yield. Further research should be conducted to study the drought stress and potassium effects on other corn varieties and in the open field trial.
Nursing Students' Perception about Nursing as a Professional Career Choice at Taif University, Saudi Arabia

Globally, the significant and increasing shortage of nurses is alarming. Nursing students’ perception towards the image of the nursing profession has an apparent impact on their self-concept, self-esteem, recruitment, retention, and performance. Aim: To describe and explore nursing students' perception of professional nursing image as a career choice at Applied Medical Sciences College, Taif University, Saudi Arabia. Subjects and methods: A descriptive online survey was conducted at previously mentioned setting. All nursing students (114) enrolled in the second semester academic year 2016/2017 and as well as agreed to participate were included in this survey. One questionnaire was used for data collection. Results: The present study's findings revealed that most of participant students entered nursing department due to their preparatory year grades. Likewise, the highest percentage of both male and female students feel proud when talking about nursing, while, a small percentage of them were shy and attack nursing. Conclusion: The majority of participant students from both gender have positive image about nursing profession. The highest percentage of positive image were among male students. Recommendations: Develop and organize an awareness program about nursing as a profession. This awareness program should be implemented in the most public visited places. Moreover, it could be very effective to arrange nursing awareness program at national day events to attract large numbers of young Saudi students into nursing.
The overwintering movement behaviour of the Red Kite (Milvus milvus) in Switzerland

Since 2015, the Red Kite project from the Swiss Ornithological Institute observes the population and behaviour of Red Kites in Switzerland in a study area between Bern and Fribourg. Previous research suggests that adaptions to changes in environmental factors during winter can vary considerably between individuals. Yet, only few studies have experimentally assessed how intrinsic (i.e. sex) or extrinsic drivers (i.e. food availability, elevation) influence the special use. With the aim to find possible changes in behaviour during winter, a feeding experiment was implemented in the winter seasons, from 2017 to 2019. We calculated seasonal home ranges of tagged Red Kites and compared their summer and winter space use respectively. In particular, we assessed the effect of season, sex, elevation and food availability on a) home range expansion b) horizontal or c) elevational shift and d) the shape or home ranges. The analysis of the GPS-data of the tagged Red Kites shows that home ranges of fed birds in low elevations (below 800 m) are smaller in winter than in summer and there is no remarkable change in shape or the location of the used areas. Unfed birds only change their winter home ranges in higher elevations and home ranges shaped more elongated than comparable winter home ranges in lower elevations. In winter, home ranges of fed birds in higher elevations (above 800 m) are usually larger and more elongated than their summer home range. Further, most Red Kites use several areas in winter, potentially due to roosting sites or anthropogenic feeding sites. In conclusion, Red Kites are more likely to change their behaviour during winter if they use home ranges at higher elevations. Table of content
A Cross-Cultural Study on Occupational Stress and Depression among School Teachers of Sikkim

The study aims to investigate the occupational stress and depression among teachers in Sikkim as teaching job has been one of the most accepted stressful occupation all over the globe. Available literatures also support that teachers have showed excessive stress which have significantly related to depression. 300 teachers (150 male and 150 female) and 100 samples each from the three cultures Nepali, Bhutia and Lepcha served as samples. The Occupational Stress Index and Beck Depression Inventory-II were employed. Results portrayed gender and cultural differences on Occupational stress and depression which invites the need of psychological diagnosis and intervention for making appropriate suggestion to gender and culture.
