How Transformational Leadership Influences the Knowledge-Sharing Process
Authors: Naeem Ayesha , Lodhi Rab Nawaz , Ullah Aman
Published: February 2021

This study aims to investigate the mediating effects of both affect-based and cognition-based trust on the relationship between using a transformational leadership style and the effectiveness of followers' knowledge sharing processes (i.e., knowledge donating and knowledge collecting). Using data collected from 287 employees at 32 pharmaceutical companies in Pakistan, the structural equation modelling (SEM) technique was utilised to analyse the hypothesised relationships. The results showed that leaders with a transformational leadership style directly affect their followers' knowledge donating and knowledge collecting processes. In addition, affect-based trust was found to fully mediate the relationships between transformational leadership and followers' knowledge donating and knowledge collecting processes, while cognition-based trust produced insignificant mediation effects. From a social exchange perspective, these findings demonstrate the importance of focusing on building affect-based trust between leaders and followers in order to develop transformational leadership that could positively influence the knowledge sharing process.

Indeed, big data has invaded the domain of tourism as a source of innovation that serves to better understand tourists' behavior and enhance tourism destination management and marketing. Thus, tourism stakeholders have increasingly leveraging tourism-related big data sources to gather abundant information concerning all tourism industry axes. However, big data has several complexity aspects and brings commensurate challenges that go along with its exploitation. It has specifically changed the way data is acquired and managed, which may influence the nature and the quality of the conducted analyses and the made decisions. Thus, this article investigates the big data acquisition process and thoroughly identifies its challenges and requirements. It also reveals its current state-of-the-art protocols and frameworks.
Clustering-Based Optimal Relay Vehicle Selection Scheme for Vehicular Adhoc Networks (VANETs)
Authors: Kumar Virender , Dahiya Pawan Kumar
Published: February 2021

Due to the high speed of vehicles in vehicular adhoc networks (VANETs), a frequent out of range area termed as uncoverage area between two neighboring road side units (RSUs) occurs. In such an uncoverage area, the reachability of the requested contents or data to vehicles is minimized due to the non-established connection between vehicles and RSUs. To maintain connectivity in an uncoverage area, various relay vehicles (RVs) selection schemes have been proposed. In this paper, a cluster-based optimal relay vehicle (CORV) selection scheme is proposed in which firstly, cluster and cluster heads (CHs) are formed and then RVs are selected depending upon remaining connection time, range, and location of vehicle. And then requested data is forwarded to DVs, which was not forwarded to vehicles in coverage area. The simulation results depict that the proposed scheme is able to retrieve maximum amount of requested contents or data in an uncoverage area by vehicles.

Published: February 2021

Disasters are often described as a result of the combination of the exposure to a hazard, the conditions of vulnerability that are present, and insufficient capacity or measures to reduce or cope with the potential negative consequences. The inability to accurately predict these types of events underscores the need for countries to have disaster response plans to mobilize appropriate resources rapidly and efficiently. A well-defined organizational structure also must be created to coordinate both national and international assistance. Human race is always a fighter of natural calamities and disasters like earthquakes, floods, droughts, cyclones, pandemics, and blizzards. After disaster, they try to establish everything buildings, establishment, infrastructure, life of human, etc. like old or better. In this paper, an effort is taken to find barriers in SCM (supply chain management) during disaster and prioritize them by multicriterion decision-making electre method.

Authors: Burrell Darrell Norman
Published: February 2021

COVID-19, also known as Coronavirus, is an emergency pandemic that has an impact worldwide. In the U.S., a disturbing trend is where African Americans are experiencing a disproportionate amount of death. The US Centers for Disease Control recommends facemasks as protection from COVID-19. Many Black men feel that wearing a mask will give them the perception of being a criminal or being threatening in a non-Black community. Many Black men feel that wearing these masks will lead to racial profiling from people and police. Many Black men have a sense of anxiety about wearing a mask because they fear that it draws unwanted attention by wearing a mask in public. This paper explores this complexity through a content analysis of current events and theoretical literature. This applied research project intends to shed light on unique challenges facing people of Black American men as they attempt to navigate COVID-19.

Published: February 2021

Funding of higher education institutions is a major growing expense for the Oman government (13–14% of the total spending in 2016) and is at par with that of other governments (e.g., 11% in the UK and 15.5% in the US). However, there has been little investigation into the funding of quality higher education in Oman. The present research project aims to explore the sources of funding at Oman universities after it opened the private education sector in 1996. The research methodology includes conducting interviews with leaders in higher education to explore different types of funding (e.g., gifts, tuition fees, government support). This will enhance our understanding, as well as that of decision-makers, regarding universities' funding sources and of the higher education landscape.

Published: February 2021

Biodiesel is derived from triglycerides by transesterification reaction with alcohol (ethanol or methanol), and has classified as a renewable, biodegradable, and nontoxic fuel. Several methods for biodiesel production have been developed, among which transesterification using alkali-catalysis gives high levels of conversion of triglycerides to their corresponding methyl esters in short reaction times. This study was conducted to extract the neem and Jatropha oil for the production of biodiesel using alkali-catalyzed reaction The samples were subjected to reaction with sodium hydroxide (NaOH), 0.2:1 w/v methanol (MeOH) to oil mole ratio, reaction temperature of 6°C, and 30 min reaction time. The final biodiesel yield obtained was 47.5% and 45.5% from the neem and the jaropha oil sample respectively. The basic physicochemical properties of the jatropha methyl ester produced from both jatropha oil samples were found to be within the ASTM D6751 specified limits.

Authors: Ikobah Joanah M. , Uhegbu Kelechi , Agbor Iwasam E. , Udoh Ekong
Published: February 2021

Introduction: Breastfeeding is essential for optimum childhood development. Although there is an increased awareness of the importance of breast milk, the Nigerian Demographic and Health Survey of 2018 showed that less than one-third (29%) of mothers in Nigeria practice exclusive breastfeeding. This may be attributed to several factors, hence the need for this study to assess the indicators and predictors of breastfeeding practices among mothers in a tertiary facility in Calabar, Cross River State. Methods: This cross-sectional study was conducted in the University of Calabar Teaching Hospital, Calabar, Nigeria. Consenting mothers of children aged six weeks to two years were sequentially recruited into the study using an interviewer-administered questionnaire. A test of association of categorical variables was done using Chi square test and pvalue was set at 0.05. Results: One hundred and twenty one children and their mothers were surveyed. Mean age of children was 6.2±3.8months and mothers was 28±25years. Exclusive breastfeeding rate for six months was 67.8%.Timely breastfeeding within one hour of life was 44.6%,ever breastfed rate was 86%. Practice of giving water alongside breast milk and use of breast milk substitute was 18.2% and 14.0% respectively. Mothers age was significantly associated with practice of exclusive breastfeeding (p=0.014) and giving water alongside breast milk (p=0.005) while birth order was associated with timely commencement of breastfeeding within one hour of life (p=0.022). Conclusion: The ever breastfed and exclusive breastfeeding rates were fairly high. However, the timely first suckling rate, increased use of breast milk substitute and giving of water alongside breast milk in the first six months of life were low. There is the need for continuous health education of mothers.

Published: February 2021

Background: Neonatal mortality remains disturbingly high in Nigeria. Helping Babies Breathe (HBB) is an evidence- based neonatal resuscitation (NR) educational program designed to teach NR in resourcelimited areas. There is no information in Nigeria on what happens after health careworkers (HCWs) complete HBB training.Aim: To determine if HCWs who received HBB training utilized the acquired knowledge and skills (K&S) and engaged in any ongoing peer training. In addition, we studied HCW turnover one year after HBB training completion.Subjects and Methods: Seventy-two HCWs were trained in HBB, and surveyed 1 year later using a 10-item questionnaire. Data analysis used measures of central tendency and t testing.Results: Most HCWs reported the use of HBB daily. The commonest NR method used was suctioning (89.5 %), followed by drying and positioning (86%), however there was 0% reported use of bagmask- ventilation. Most HCWs (98%) reported sharing K&S with colleagues. Following training,100% HBB trainers remained at original employment but 53% HBB providers moved to new employment and did not utilize their HBB K&S at their new employment site.Conclusion: Frequent, brief, refresher practice sessions and implementation of a system for training new hires may improve HCW readiness for NR and their peer mentoring capabilities. Ensuring adequate equipment availability is critical for HCW to utilize acquired K&S. Significant HCW turnover occurred within a year of training. Trained HCW who left to new employment subsequently had limited impact at their new place of employment.

Published: February 2021

The latest available data indicate that since 2018, poultry has been the most widely consumed meat in the world. However, poultry meat is frequently highly contaminated with microorganisms. Total viable count (TVC), which is also called total aerobic mesophilic bacteria (TAMB), is an indicator of bacterial quality. The aim of this study was to investigate the factors associated with bacterial contamination of poultry meat at butcher shops. The study was carried out from January 2018 to July 2020 and included 10 butcher shops in Biskra (Algeria). Different poultry meat samples (n=159) were purchased from butcher shops, prior to and after the outbreak of COVID-19. Each sample was tested for TAMB and faecal coliforms. In this study, one independent variable was quantitative, which is the contamination of poultry meat by faecal coliforms, and nine variables were categorical: whole carcass packed at the slaughterhouse or cut at butcher shop, sample type: thigh skin, thigh meat, neck skin, liver, turkey escalope, and before or after the outbreak of COVID-19. Descriptive statistics, multiple correspondence analysis (MCA) and multiple linear regression were used to examine if the various factors identified were associated with the bacterial contamination of poultry meat. The average level of contamination of poultry meat by TAMB was: 6.40 ± 0.81 log10 CFU/g. MCA results with graphical representations of qualitative and quantitative variables show the interfactor relationships. The multiple regression model explained 48.6% of the TAMB variations and estimated TAMB contamination of poultry meat according to the equation: Y= 0.477 X1 + (- 0.639) X2 + (- 0.557) X3 + (- 0.295) X4 +5.522; Y (TAMB in log10 CFU/g), X1 (faecal coliforms in log10 CFU/g), X2 (Before/after COVID-19), X3 (Turkey escalope), X4 (Carcass/cut). Identifying the factors associated with bacterial contamination of poultry meat is necessary to implement effective preventive measures in butcher shops, thus significantly reducing contamination levels and providing customers with high quality poultry meat.

Published: February 2021

The exposure of the body to stress, regardless of whether it comes from physical, chemical or emotional stimuli from the environment, causes an inadequate adaptation of the organisms which can contribute to the development of various diseases. Abnormally high blood concentrations of cortisol, known as stress hormone, lead to the development of a hormonal disorder called hyperadrenocorticism or Cushing’s syndrome. In the majority of cases, Cushing’s syndrome is diagnosed when symptoms are apparent, and screening endocrinological test confirms the existence either of increased cortisol production or decreased sensitivity of the hypothalamic-pituitary-adrenal axis to negative glucocorticoid feedback. In our research, we examined a total of 23 male and 7 female dogs that were suspected to have Cushing’s syndrome, based on history and clinical signs. A total of 15 male and 5 female dogs were positive for Cushing’s syndrome (HAC group), whereas the remaining dogs were used to form non-HAC group. Using the apparatus IDEXX “Vet Test 8008”, the following biochemical parameters were determined: glucose, urea, creatinine, phosphorus, calcium, total protein, albumin, globulin, alanine aminotransferase, alkaline phosphatase, bilirubin, cholesterol, and amylase. Regarding haematological parameters, the following parameters were investigated: erythrocytes, leukocytes, platelets, erythrocyte indices (MCV, MCH, MCHC, RDW), white blood cell count, haemoglobin and haematocrit, using “Laser cite vet lab Station” (IDEXX). No significant differences in haematological and biochemical blood parameters were noticed between the HAC and the non-HAC group of dogs. However, dogs suffering from Cushing’s syndrome had a higher value in the number of erythrocytes compared to the control group. The finding that has to be payed attention to is the difference in platelet count between the control group of dogs and dogs suffering from Cushing’s syndrome.

Mucuna bracteata is a type of Leguminosae Cover Crop (LCC) which is widely used in Indonesian plantations. The advantage of Mucuna bracteata is that it grows fast. Based on this, a study was conducted to see the rate of difference in the number of internodes planted which could accelerate the growth and development of Mucuna bracteata. The research was carried out in the practical garden area of ​​the Medan Agricultural College of Agribusiness (STIPAP). The research was conducted from May to June 2020. This study used a non-factorial randomized block design (RBD), which consisted of 1 treatment with 4 levels, namely R0 (1 rolled segment), R1 (2 rolled sections), R2 (3 rolled humps), R3 (4 rolled humps) and with 5 repetitions. The results showed that the treatment of R2, namely 3 bundles of rolled knuckles, gave the best effect on the parameter increase in tendril length, namely 89.66 cm, the increase in the number of tendrils, namely 6.38, the increase in the number of leaves, namely 12.50 strands, the increase in the number of segments, namely 11.32 pieces, and the measurement of the root volume, namely 13.00 ml. The treatment of the number of bunded knots had a significant effect on the parameters of tendril length, number of tendrils, number of leaves, number of internodes, and volume of roots.
Lokális geopolitika és területfejlesztés
Authors: Tőkés Tibor
Published: February 2021

A lokális geopolitika nem más, mint a geopolitikai módszerek alkalmazása a helyi konfliktusok értelmezésében. E terület csak a közelmúltban került a francia geopolitikai kutatások témái közé. A területfejlesztés geopolitikájának vizsgálata a lokális geopolitika egyik fontos szakterülete Franciaországban. A területfejlesztés középszintjének kérdése erőteljesen foglalkoztatja a francia szakembereket, éppen ezért érdemes megvizsgálnunk e kérdést, hiszen a magyar területfejlesztés középszintjével kapcsolatos viták Magyarország esetében is folyamatosan napirenden voltak az elmúlt időszakban.

Abstract
Objective: To determine the pattern of antimicrobial sensitivity of common microorganisms isolated from diabetic foot infections presenting at a tertiary care center in North West, Pakistan.
Methods: 201 patients were included in the study, which was conducted over a period of 08 months from January 2019 to August 2019, at the Diabetes & Footcare Clinic (DFC), Mayo Hospital Lahore. Deep-seated tissue samples (0.5 x 0.5 cm) were taken from ulcer bed and immediately sent for culture & sensitivity (C&S) testing. Antimicrobial susceptibility was determined in accordance with Clinical & Laboratory Standards Institute (CLSI) guidelines. Statistical analysis was performed using SPSS version 26.0. Data was presented as Mean ± SD for continuous variables & frequency with percentage for categorical variables.
Results: Mean age of participants was 53.05 ± 10.70, from which 66.7 % (134) were male. Grade 3 DFUs (51.7%) and grade 2 DFIs were most prevalent (62.7%). Out of 201 tissue specimens, 389 bacterial isolates were collected. Monomicrobial specimens accounted for 28.4%, with the rest (71.6%) being polymicrobial. Gram negative organisms were 238 (61.11%) while the rest (38.89%) were gram positive organisms. There was a high incidence of methicillin resistant S. aureus (MRSA) at 64.58%. Highest susceptibility of S. aureus was reported with vancomycin and fusidic acid at 100% and 79.35%.

Yam is an important tuber crop in Nigeria. Some locations in South west Nigeria (Oyo State, Ondo State, Osun State, and Ogun State) were surveyed to find out the existence and the abundance of diversity of white guinea yam (Dioscorea rotundata). It was discovered that there are also diversity in other species of landrace yams (Dioscorea cayenensis, Dioscorea alata, Dioscorea dumentorum). One unidentified species of yam was found in Ondo State. This species also exist in Osun State. Some of the yam diversities are endangered. Genetic erosion of these yam diversities is imminent because of the decline of the traditional farmers growing these diversities; also because of modern commercial farms that tend to mono-cropping of improved variety and also because of problem of storage of yams and especially ex-situ conservation of yam genetic resources of yam in Nigeria.
For or against Brexit? Justifying oppositional arguments in online discussion
Authors:   Information Technology and Communication Sciences, Tampere University, Tampere, Finland, Savolainen Reijo
Published: February 2021

Introduction. This investigation examines argumentation about political issues occurring in online discussion groups. A case study was made by concentrating on debates about Brexit - the prospective withdrawal of the United Kingdom from the European Union. Method. Building on Toulmin’s model for argument patterns, it was examined how oppositional arguments about Brexit were grounded by drawing on facts and opinion-based evidence and how the evidence of information these types was justified. To this end, a sample of 40 discussion threads initiated before the 2016 Brexit referendum were downloaded from PoliticsForum - an online platform. Analysis. The data consisting of 1563 messages were scrutinized by means of descriptive statistical analysis and qualitative content analysis. The focus was placed on the latter method by analysing the ways in which the discussants justified the rebuttal of opposing arguments. Results. Oppositional arguments justifications were mainly based on the description of personal opinions and negative evaluation of opposing views. Analytic approaches to justification based on explanation and comparison were less popular. This preference is probably due to the lower cognitive effort required while simply describing the attributes of an entity or judging its positive or negative qualities by drawing on one’s beliefs and experiences. Conclusions. Argumentation occurring in online platforms will form an increasingly important part of political struggles. On the other hand, online debates on controversial issues such as Brexit tend to be broad rather than deep.
