Self-Reported Habitual Practices and Perceptions of Young Drivers in Sri Lanka
Authors: Amarasingha N. , Firdhaws H.M.M.
Published: May 2021

Crashes on the road have become a significant socio-economic problem. Younger generations, who have lesser experience in driving, are at greater risks of facing road accidents. It is therefore important to identify driving practices and perceptions of young and inexperienced drivers at an early phase of exposure so that factors that improve safe driving can be identified.This study analysed 400 young and inexperienced drivers’ self-reported habitual practices and perceptions based on a questionnaire survey. The questionnaire focused on supervision of early driving, limitation made by parents, accident and traffic offenses by these youngsters as drivers as well as other habitual driving practices. Analyses were done using reliability statistics, inter-item correlation, likelihood ratio tests, and parameter estimates. The highest inter-item correlation value was 0.467 for the pair of overtaking vehicles in restricted areas and taking the chance to speed and run a yellow light when it is about to change to red. Driving after alcohol consumption, mobile phone usage, taking an illegal U-turn at restricted areas, non-use of signals when changing lanes and overtaking a slow driver from the left side were influenced non-use of seat-belts by young drivers. These habitual practices while driving highlighted the importance of early intervention to improve road safety.In conclusion, there is always one or more habitual driving practices that have affect the other driving habits of a young driver.

Published: May 2021

In questo lavoro vengono riportati i risultati del monitoraggio della fauna dei macrolepidotteri notturni di una azienda olivicola a conduzione biologica condotto da luglio 2018 a giugno 2019. L’area di studio è posta nella Stretta di Catanzaro e precisamente nel comune di Marcellinara, a circa 200 metri di quota. Sono state utilizzate 8 trappole luminose collocate all’interno dell’oliveto e ai suoi margini, dove è ancora presente una vegetazione seminaturale sottoposta ad un grado di disturbo variabile. Il monitoraggio, effettuato con cadenza mensile, ha permesso la raccolta di 7.569 esemplari appartenenti a 332 specie, fra le quali le più abbondanti sono state Eilema caniola, Peribatodes rhomboidaria, Dysauxes famula e Spodoptera exigua. Queste specie da una parte sottolineano la natura antropica dell’ambiente indagato e dall’altra il suo carattere mediterraneo. Oltre all’interessante rinvenimento di alcune specie solitamente rinvenute a quote più elevate, vanno evidenziate le presenze di Agrotis lata, definitivamente confermata in Italia continentale e segnalata per la prima volta in Calabria, e Rhodostrophia pudorata, per la quale questo è il rinvenimento più settentrionale in Italia. Entrambe le specie sono piuttosto frequenti in Sicilia e la loro presenza nella penisola è stata segnalata molto di rado. Inoltre, si riporta il primo rinvenimento di Eilema rungsi in Calabria.

Integrating an Evidence-Based Medicine Curriculum into Physician Assistant Education
Authors: Reinhold Martina Ingeborg , Bacon-Baguley Theresa Ann
Published: May 2021

Background:

Medical knowledge continuously evolves and to help health care providers to stay up to date, the evidence-based medicine (EBM) model has emerged. The practice of EBM requires new skills of the health care provider, including directed literature searches, the critical evaluation of research studies and the direct application of the findings to patient care.

Methods:

This paper describes the integration and evaluation of an evidence-based medicine course sequence into a Physician Assistant curriculum utilizing the expertise from faculty trained in basic science, nursing and primary care practice.

Results:

Collaboration of faculty with different educational backgrounds resulted in a course series that was equally strong in all aspects of EBM. This new course sequence teaches students to manage and use the best clinical research evidence to competently practice medicine. To assess the effectiveness of the EBM sequence a survey was developed and administered at the beginning and end of the sequence.

Conclusion:

EBM knowledge gained is essential to effective clinical decision making and this newly developed tool specifically helps to identify student competencies within the defined course objectives. Contributing to the uniqueness of the tool are case-based questions requiring integration of EBM knowledge by the student.

Published: May 2021

Clinical decision support tools should have a role in the management of patients with comorbidities. But until now, these tools have offered minimal support for managing such patients. BMJ Best Practice has recently launched a new resource – the comorbidities tool from BMJ Best Practice. This article describes and contextualizes the themes discussed at a workshop with junior doctors on clinical decision support for health-care professionals on comorbidities. Comorbidities were vitally important to the clinical practice of all the doctors in the workshop, but most perceived a lack of specific teaching and support on the subject of comorbidities. Most of the doctors found it a challenge to manage patients with comorbidities and were enthusiastic about a tool that would help them overcome these challenges and improve their clinical decision-making. We found that a workshop led by junior doctors provided deep insights into the issue of clinical decision support for patients with comorbidities.

Published: May 2021

Objective:

The purpose of this exploratory study was to examine adverse childhood experiences (ACEs), knowledge, and screening practices.

Methods:

A convenience sample of pediatric primary care providers in a health-care system within a high-prevalence state were invited to participate. The original 12-item survey addressed familiarity, tools, barriers, and prevalence regarding ACEs.

Results:

Study participants reported familiarity with ACEs; however, only 23% reported the use of any screening tool(s). Primary barriers included time and lack of staff and/or knowledge/training. About 77% of respondents have encountered at least eight of the 10 major types of ACEs. Most frequently encountered ACEs included parental separation or divorce, substance abuse in the household, and mental illness in the household. About 73% expressed interest in continuing medical education.

Conclusions:

Provider knowledge/familiarity with ACEs does not imply systematic screening. An efficient and evidence-based standardization for screening merits consideration. Continued education and training may address barriers to both provider understanding and screening of ACEs.
Qualitative Analysis of Student Responses to Survey Questions Investigating Student Perceptions of Case-Based Learning
Authors: Fogelberg Katherine , Simons Micha , Anderson Stacy
Published: May 2021

Background:

This qualitative study applied discourse analysis to open ended question responses of fourth semester veterinary students enrolled in case based learning (CBL) course. This was the first CBL course incorporated into the curriculum and was delivered via teams of two professors for each of eight sessions.

Aims:

Questions were designed to investigate student perceptions of CBL and determine how it impacted their learning.

Results:

Results were reported to faculty to help them deliver high quality, engaging, and challenging CBL sessions that pushed students without being discouraging. From a cognition and learning perspective, students felt that CBL helped with learning at all levels of Bloom's taxonomy, encouraged metacognition, and helped prepare them for clinical rotations and postgraduation careers. From a mechanics and delivery perspective, students desired resources to help them use cases to learn about species in which they have a particular interest beyond the classroom; wanted interactive sessions and in class assessments, primarily involving individual responses using audience response software (clickers); enjoyed class and small group discussions; and preferred little to no out of classwork or assignments unless explicitly related to the case and expectations for the assignment(s) is/are clearly laid out.

Conclusions:

Overall, most students wanted more CBL and found it engaging, fun, and supportive of their learning.

Published: May 2021

Objective:

The objective of this study was to outline the process and results of a curriculum map revision.

Methods:

A revision process was developed for curricular competencies and measurable abilities (MAs). A crosswalk of the original MAs to the revised MAs and curriculum mapping reports for the 2018–2019 and 2019–2020 academic years were evaluated.

Results:

The number of competencies decreased from 12 to 11 and MAs increased from 90 to 98. The MA word count decreased from 1719 to 1498 (12.9%); 25 were combined, 26 were deleted, seven were divided, and 47 were created. Course learning outcomes (CLOs) mapped to a mean of 139 and 39 MAs prerevision and postrevision, respectively. Prerevision, 86.9% of CLOs mapped to an MA. Postrevision, 100% of CLOs mapped to an MA.

Conclusion:

Our revision process reduced redundancy and complexity and addressed gaps. Institutions searching for a model to assist with curriculum mapping and revisions may find our process useful.
Study of the effect of early and late acute rejection episodes on renal graft survival
Authors: Ragheb Ahmed , Kora Mahmoud A. Elaziz , Hassan Yassin F. , Kasem Heba E.
Published: May 2021

Background

It has been demonstrated that acute rejection (AR) episodes are major risk factors of renal allograft loss. Still the impact of early acute rejection (EAR) on long-term graft survival is debated. The aim of this study was to study the impact of early acute rejection (EAR) and late acute rejection (LAR) on renal allograft survival.

Patients and methods

In this retrospective study we investigated the timing and frequency of AR episodes in 120 kidney transplant recipients for a 3-years period. Patients were divided into three groups; Group I: No acute rejection (No-AR), Group II: Early acute rejection (EAR), and Group III: Late acute rejection (LAR). The graft survivals in the three groups and the associated risk factors were analyzed.

Results

Of the 120 recipients one patient died (0.08%) and 14 grafts were lost (11.6%). The graft survival durations were 35.2, 23.6 and 27.2 months and the 3-years survival rates were 93%, 63.3% and 66.7% in the three groups respectively. The graft survival durations and rates were significantly higher in group I compared to groups II and III with no significant differences between the last two groups.

Conclusion

Both EAR and LAR have deleterious effects on graft survival following kidney transplantation.

Published: May 2021

Background

Variable prophylaxis regimens have been adapted to guard against cytomegalovirus (CMV) after renal transplantation. High-dose valganciclovir (VGCV) is the gold standard, but it is of very high cost. Herein, we compared another low-cost regimen [low-dose valacyclovir (VCV)] with low-dose VGCV to assess the efficacy and safety of VCV.

Patients and methods

This is a single-center randomized controlled trial that was held in Urology and Nephrology Center, Mansoura University, Egypt. The patients were divided into two groups according to CMV prophylaxis regimen used. Group I included 40 kidney transplant recipients who received low-dose VCV (2 g b.i.d.), and group II included 40 kidney transplant recipients who received low-dose VGCV (450 q.d.).

Results

Our patients’ age ranged from 18 to 58 years, and the majority were males. The median years of transplantation were 1.9 years. Efficacy of both regimens was similar. Interruption of VCV was more frequent, with significant difference, and it was associated with increased incidence of CMV infection but without any statistical significance. The cost of low-dose VGCV was very high in comparison with low-dose VCV.

Conclusion

Low-dose VCV showed the same efficacy and safety of low-dose VGCV as CMV prophylaxis protocol after kidney transplantation.
Plasma cortisol level and its relation to in-hospital mortality in acute kidney injury patients
Authors: Yousef Elshahat A. , El-Kannishy Sherif , Arfa Lamia F. , Mahmoud Rasha
Published: May 2021

Background

Critically ill patients are at risk of developing critical illness-related corticosteroid insufficiency (CIRCI). This may present as hypotension, unresponsiveness to catecholamine infusions, and/or ventilator dependence. Acute kidney injury (AKI) usually complicates critically ill patients and is associated with hemodynamic instability. There is usually failure to predict the severity and to assess the response to therapy in AKI. The aim of this study was to assess the plasma cortisol level and its relation to hospital mortality in AKI patients.

Patients and methods

This is a prospective, observational study that included 66 patients with AKI admitted to the Dialysis and Nephrology Unit, Mansoura University Hospital, who were assessed clinically, followed by cortisol level assay done at the day of admission. Patients were followed clinically and biochemically till discharge. Patients were classified according to random plasma cortisol level into two groups: group 1 included 14 patients with random plasma cortisol of less than 10 μg/dl (CIRCI group) and group 2 included 52 patients with random plasma cortisol of greater than or equal to 10 μg/dl.

Results

There was a significant increase in platelet count in group 1 compared with group 2, while there was a significant decrease in serum potassium level in group 1 compared with group 2. Moreover, there was a significant decrease in urine output volume in group 1 compared with group 2 (P=0.03). Finally the hospital mortality rate was significantly higher in group 1 (CIRCI group) compared with group 2 (P=0.004).

Conclusion

AKI patients with low cortisol level at admission have higher mortality rate during the hospitalization period.
Scaling limits of bosonic ground states, from many-body to non-linear Schrödinger
Authors: Rougerie Nicolas
Published: May 2021

How and why could an interacting system of many particles be described as if all particles were independent and identically distributed? This question is at least as old as statistical mechanics itself. Its quantum version has been rejuvenated by the birth of cold atoms physics. In particular, the experimental creation of Bose–Einstein condensates leads to the following variant: why and how can a large assembly of very cold interacting bosons (quantum particles deprived of the Pauli exclusion principle) all populate the same quantum state? In this text I review the various mathematical techniques allowing to prove that the lowest energy state of a bosonic system forms, in a reasonable macroscopic limit of large particle number, a Bose–Einstein condensate. This means that indeed in the relevant limit all particles approximately behave as if independent and identically distributed, according to a law determined by minimizing a non-linear Schrödinger energy functional. This is a particular instance of the justification of the mean-field approximation in statistical mechanics, starting from the basic many-body Schrödinger Hamiltonian.
Potential medicinal plant remedies and their possible mechanisms against COVID-19: A review
Authors: Ugwah-Oguejiofor C.J. , Adebisi I.M.
Published: May 2021

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) outbreak was first reported in Wuhan, a city in Hubei Province of China in December, 2019 and is known to be responsible for the novel coronavirus disease (COVID-19). COVID-19 was declared a pandemic in March, 2020 and since then, it has caused a number of deaths in over 200 countries around the world. Extensive researches have continued in the search of effective vaccines or drug compounds against SARS-CoV-2 and a total of 64 vaccines are currently in clinical trials with 12 currently approved for use by different regulatory bodies, depending on the country. Since the outbreak of SARS-CoV-2, many countries have utilised traditional herbal medicines alongside conventional drugs for the treatment of infected patients. In this review, traditional medicines used to prevent or treat SARS-CoV-2 infection are listed along with the plant parts as used by the traditional healers. Additionally, the possible mechanisms responsible for this preventive or therapeutic outcome are also identified and listed. Our literature search was conducted using Google Scholar, PubMed, Scopus and WHO website. Unpublished reports such asdissertations and theses are not included. Plant parts including roots, leaves, flowers, seeds and so on have been used in the treatment of COVID-19. These traditional medicinal herbs may exert their anti-COVID-19 activity by direct inhibition of the virus replication or entry. Some may act by blocking the ACE-2 receptor, SARS-CoV helicase, Type II Transmembrane Serine Protease (TMPRSS2) and which are required by SARS-CoV-2 in order to infect human cells. Others act by inhibiting the SARSCoV-2 life-cycle related proteins, namely chymotrypsin-like cysteine protease (3CL-pro) and Papain-like protease (PL-pro). Medicinal plants are promising alternative medicines for the treatment or prevention of SARS-CoV-2 infection. Further researches, are needed to decipher their active components and structures which may suggest clues for the development of drugs against this novel coronavirus.

Impact of doubling the recommended dose of Magicforce (Lambda-Cyhalothrin + Dimethoate) on major associated arthropods and performance of watermelon
Authors: Okrikata E. , Agere H. , Adepoju I.O. , Malu S.P.
Published: May 2021

Some crop growers hold the view that application of pesticides at higher than the manufacturer's recommended doses results in better pest control and crop productivity. The veracity of this perception was evaluated in field experiments at the experimental field of Federal University Wukari. A recommended insecticide and acaricide; ® Magicforce (Lambda-cyhalothrin 15g/L + Dimethoate 300 g/L) was evaluated against insect pests of watermelon (Citrullus lanatus Thunb.) and other associated beneficial arthropods. The  experiments were laid in a Randomized Complete Block Design with five treatments (control inclusive). Data collected includes  arthropod (pest and beneficial) densities, crop growth, and number of fruits at the early-fruiting stage which were analyzed using  variance analysis after appropriate transformations. Student's t-test was used to compare early- and lateseason's variables while  correlation and regression analyses were used to determine relationships between key variables. Results showed that plots treated with double the highest manufacturer's recommended dose of ® Magicforce (cost implication of ₦ 144,000) had lower pest (leaf beetle species and Bactrocera cucurbitae) and beneficial arthropod (predatory ants, spiders and Apis mellifera) densities than those treated with the lowest (cost – ₦ 48,000) and highest (cost – ₦ 72,000) recommended doses. Their plant growth (vine length and number of leaves) and fruit production were however comparatively lower though largely statistically comparable. The ® relationship between the quantity of Magicforce applied and number of fruits produced were though positive, 2 2 only moderate and insignificant in both early- (r = 0.665, R = 44.3%, p = 0.220) and late- (r = 0.659, R = 43.4%, p = 0.227) crops. The results revealed that the application of double the manufacturer's recommended dose of ® Magicforce (with its comparatively higher cost implication of 100 – 200%) suppressed growth  of watermelon by 1.96 – 6.20%, and impeded fruit production by 9.14 – 13.30%. While there is need to verify the mechanism of this key finding, the need to source for genuine pesticides and follow manufacturer's recommended doses a re highlighted.

THE DEAD-Box PROTEIN Csha IN STAPHYLOCOCCUS AUREUS CONTAINS ATP-INDEPENDENT DNA STRAND ANNEALING AND EXCHANGE ACTIVITIES
Authors: DIEU NGUYEN HANH THI , PHAM TAN-VIET , NGUYEN NGOC-AN , TRAN GIA-BUU
Published: May 2021

DEAD-box proteins (DBPs) that are usually RNA helicases have important roles in eukaryotic and bacterial RNA metabolism. Recent studies have reported that certain prokaryotic DBPs exhibit ATP-independent nucleic acid displacement and annealing activities. We investigated one putative RNA helicase, CshA DEAD-box protein, from vancomycin-resistant Staphylococcus aureus strain Mu 50 for ATP-independent activities on nucleic acids. We herein report that CshA has two novel ATP-independent activities - annealing of complementary single-stranded DNA (ssDNA) and strand exchange on short double-stranded DNA (dsDNA). These DNA strand annealing and exchange activities are independent of Mg2+ ion or ATP binding and hydrolysis. ssDNA annealing activity as well as versatile DNA strand exchange activity of CshA suggests a possible role in dsDNA break repair processes.

Published: May 2021

A magnetic multi-wall carbon nanotube (MCNTs) nanocomposite was synthesized and was used as an adsorbent for removal of oil from aqueous solutions. The MCNTs nanocomposite was composed of commercial multi-wall carbon nanotubes and iron oxide nanoparticles. The property of this magnetic adsorbent was characterized by scanning electron microscopy, X-ray diffraction and VSM. Adsorption characteristics of the MCNT nanocomposite was examined using diesel oil (DO) as adsorbate. The sorption capacity was affected significantly by the initial concentration of DO, sorbent amount and contact time. Batch experiments were conducted to investigate the affect of different DO initial concentration (ranging from 0.2 to 1.0%) and contact time (10 to 90 min) to the removal efficiency. This MCNTs nanocomposite can be recycled conveniently from water with the assist of an external magnet because of their exceptional properties.

Clients´ Perceptions of Sales Force Expert Power
Authors:   , Fricke Stefan
Published: May 2021

Expert power is based on the awareness that a person in a power relationship possesses valuable knowledge, information, or skills (Raven, 1992, 2008). It builds customer trust, long-term relationships, customer satisfaction, loyalty, and exit barriers. The buyer´s preferences for a product or solution are shaped by sales force expert power (Doney & Cannon, 1997; Clauss & Bouncken, 2018). With these preferences, the buyer participates in the decision-making process, where the mechanisms of organisational buying find application. However, what remains unclear is which attributes a buying centre specifically associates with sales force expert power, when and how the perception of sales force expert power alters in the buying process, also which factors are responsible for it are issues that have not yet been discussed in the context of group decision-making in buying centres, and finally to what extent does sales force expert power influences the decision frame of each member of the buying centre. To address these gaps, the aim of the study is to create an approach by which sales forces can consciously manage and enhance the clients´ perceptions of sales force expert power. For this purpose, Alpha Software customers from various industries were interviewed immediately after their purchase decision regarding the perception of sales force expert power and what influence this perception had on the buying centre’s decision. The findings of the study indicate an overload of sales force expert power can lead to mistrust and uncertainty. The perception of sales force expert power is important in all stages of the buying process. In early stages product knowledge is perceived more strongly while the perception of change knowledge in final stages predominates. Information exchange and recommendations lose their impact due to an unprofessional approach to change which minimises the perception of expert power significantly. Due to the intensity of change and how the change is perceived the perception of sales force expert power alters. Business customers, unlike consumers, expect a professional approach to change rather than benevolence. The interviewed clients perceive the software conversion project as a change project and expect the sales force to be approached and addressed accordingly. Change knowledge is cited as an important attribute for sales force expert power, which can advance the clients´ perceptions of sales force expert power.
A liberdade de expressão e o direito ao esquecimento
Authors: Silva Alves Guimarães João Alexandre , Silva Alves Guimarães Ana Júlia
Published: May 2021

O Direito à liberdade de expressão é reconhecido como um dos direitos fundamentais para o livre desenvolvimento da personalidade, juntamente com a imagem, honra e a vida privada. Porém, com o advento da tecnologia, as informações pessoais começaram a ser amplamente divulgadas, principalmente pelas mídias de massa e, no presente momento, nas redes sociais, sendo publicado pelo próprio detentor dos dados. O Direito ao Esquecimento surge como uma resposta e uma limitação quando a divulgação dessas informações pessoais inviabiliza que o detentor dos dados tenha sua vida cotidiana de forma normal. Desde 1890, nos Estados Unidos da América, com a preocupação da invenção da câmera fotográfica que poderia invadir a privacidade do cidadão comum, inicia a ideia da privacidade, aplicado ao caso Malvin vs. Reid, de 1931 na Califórnia, onde aplica-se uma limitação sobre a divulgação de um filme que invadia a privacidade de uma família. Posteriormente, no famoso Caso Lebach na Alemanha, onde pela primeira vez uma corte constitucional decidiu a favor da limitação da liberdade de expressão e da liberdade de comunicação. Com o estabelecimento do princípio constitucional da autodeterminação informacional e com o advento do Regulamento Geral de Proteção de Dados com a previsão do Direito ao Esquecimento de forma expressa, no art. 17.º, o Tribunal de Justiça Federal da Alemanha reconheceu que o Direito ao Esquecimento e a Liberdade de Expressão e Comunicação são direitos fundamentais, mas não absolutos, e cabe a corte que está julgando decidir no caso concreto qual desses direitos deve prevalecer.

Interferon-alfa in the management of cystic craniopharyngioma in children under 5 years of age
Authors: Tude Melo Jose Roberto , Santos Felipe Reynan Paiva Vieira , Da Silva Igor Campos , Barreto José Henrique Silva
Published: May 2021

Introduction: the best therapeutic option for the management of craniopharyngioma in younger children remains controversial, ranging from complete surgical resection, partial surgical resection associated with radiotherapy and application of chemotherapeutic agents such as bleomycin and interferon-alfa.
Objective: to verify the response to treatment with interferon-alfa via Ommaya reservoir in a group of children under 5 years of age with diagnosis of cystic craniopharyngioma.
Methods: description of a case series through consecutive review of medical records of children under 5 years of age diagnosed with cystic adamantinomatous craniopharyngioma who had an Ommaya reservoir catheter surgically implanted for intratumoral application of interferon-?.
Results: seven children aged 18 to 60 months (median 46 months) with the abovementioned diagnosis and treated with interferon-alfa between 2010 and 2019, according to a pre-established protocol, were identified. A reduction in tumor volume, ranging from 88 to 100%, one year after the end of treatment was observed in the study sample. There were no complications that justified the interruption or modification of the established therapy.
Conclusion: in all the cases evaluated of children less than 5 years of age with predominantly cystic adamantinomatous craniopharyngioma we observed a reduction of tumor volume on magnetic resonance imaging one year after the end of treatment with interferon-alfa.
Study on Hydrochemical Characteristics of Ordovician Limestone in Jiaozuo Mining Area
Authors:   School of Institute of Resource& Environment, Henan Polytechnic University, Jiaozuo 454000, Henan, China, Su Qiaoqiao
Published: May 2021

In order to understand the source of groundwater inrush and its hydrogeochemical evolution path truly, determine the evolution characteristics and development trend of water cycle, and effectively solve the problem of water disaster in mining area. In this paper, Jiaozuo mining area, a typical large water mining area of North China type, is selected as the study area. Taking the Ordovician aquifer in the study area as the research object, the Ca2+ hydrochemical equilibrium model of Ordovician limestone water system is established by analyzing the characteristics of concentration gradient field and the relationship between the hydrochemical ions (Ca2+、K++Na+、Mg2+、Cl-、SO42-、HCO3-) and TDS in the mining area, it made a systematic study on the characteristics of Ordovician limestone water circulation, and analyzed the recharge, runoff and discharge characteristics of groundwater in different areas of the mining area. The results show that the Ordovician limestone water in the Jiaozuo mining area has a weak leaching effect in the north and southwest, but a strong leaching effect in the southeast, which shows a runoff characteristic from the north and southwest to the southeast.

Authors:   Science Department, College of Agriculture Zuru, Kebbi State, M. Mukhtar
Published: May 2021

Groundwater is one of the most precious natural resource which supports human health, economic development and ecological diversity. Remote sensing and Geographical Information System (GIS) Techniques have been effectively used for the investigation of the potentiality of groundwater resource in Fakai local government area. The dataset for this research work are Landsat 8 Operational land imager (OLI), ASTER DEM, Topographical map and Geological map from which the essential criteria were obtained. The study used Weighted Linear Combination approach which involves mathematical weighing and ranking of the criteria. Multi-criteria evaluation was carried out on all the criteria using the Weighted Linear Combination approach in ArcGIS 10.4. Spatial analysis was carried out on the derived result using the Suitability Index (SI) value created from pairwise comparison analysis. The suitability map for groundwater recharge in the study area was hence produced using the suitability index. The result shows four classes for the study area. The classes include highly suitable, moderately suitable, less suitable and least suitable. Thus, the area most suitable for groundwater are found most towards the northern part, around the center and some regions in the northern part of the study area this serves as an indicator that most of the study area has good potential for groundwater recharge.

Published: May 2021

This study examined the impact of trade liberalization on manufacturing sector performance in Nigeria from 1970 to 2018. A multiple regression model was developed to achieve the study’s objectives with real manufacturing growth rate (RMGR) as proxy for manufacturing sector performance. Import penetration, export penetration, dummy variable for structural adjustment programme alongside other control variables were used. Using the Autoregressive Distributed Lag (ARDL) bound testing for cointegration approach, it was found that all the variables for the model had long run relationship. Furthermore, the ARDL results revealed a mixed impact of trade liberalization on the performance of the manufacturing sector. Specifically, while trade liberalization exerted insignificant positive impact on RMGR in the short run, the impact was positive and statistically significant in the long run. Consequently, the study recommended policies that would encourage the importation of capital goods to enhance manufacturing productivity in Nigeria.
