Critical Success Factors to Improve the Adoption of Social Media in Teaching and Learning: A Case Study at a Traditional University
Authors: Murire Obrain , Cilliers Liezel 
Published: March 2019

Mobile devices and social media tools are two emerging technologies that have positively influenced teaching and learning practices at traditional universities. Regardless of the popularity of social media, few lecturers make use of these tools for educational purposes. The objective of this paper was to identify critical success factors to improve the adoption of social media among lecturers at a traditional university in South Africa. The unified theory of acceptance and use of technology (UTAUT) was chosen as the theoretical foundation for this study. A quantitative, survey data collection method was uses to collect data. A questionnaire was distributed to all academics at the university, with a response rate of 39 %. From these, descriptive statistics were used to analyse data and the Pearson chi-square test was used to establish the association amongst different variables. The following CSFs were identified to enhance emerging technologies at traditional universities: management support; provide adequate ICT infrastructure and resources; provide sufficient training for lecturers, and introduce a champion to promote social media. The study, therefore, recommends that these four critical success factors must be considered by universities to adopt social media in teaching and learning.<div><hr align="left" size="1" width="33%" /><div> </div><div> </div><div> </div></div>

België telt in totaal 5 700 000 auto’s, waarvan zo’n 650 000 bedrijfswagens in 2016. Naar schatting rijden er iedere dag ongeveer 100 000 bedrijfswagens in, uit en binnen het Brussels Gewest. Bedrijfswagens hebben dus zeker een grote impact op de mobiliteit in het gewest. Dit artikel beschrijft eerst en vooral het fiscale regime van de bedrijfswagens en de specifieke kenmerken van dit type wagens. Vervolgens gaat de synthesenota dieper in op de kenmerken van de bedrijven die deze voertuigen aanbieden en op het profiel van de werknemers die een bedrijfswagen ter beschikking gesteld krijgen. Verder analyseren de auteurs de afstanden die bedrijfswagens afleggen en hun impact op het autoverkeer en schatten zij de fiscale en loonimpact van het systeem in. Ook worden de gevolgen van bedrijfswagens voor het milieu kort geanalyseerd qua productie van broeikasgassen en impact van de emissies op de volksgezondheid. Tot slot plaatst het artikel de uitdagingen en debatten rond de kwestie van de bedrijfswagen op Brussels en op nationaal niveau in perspectief.
Company cars: identifying the problems and challenges of a tax system
Authors: May Xavier , Ermans Thomas , Hooftman Nils 
Published: March 2019

There were approximately 650 000 company cars in Belgium in 2016 of a total of 5 700 000 cars on the roads. It may be estimated that approximately 100 000 company cars enter, exit or are driven in the Brussels Region every day: they therefore undoubtedly have a significant impact on regional mobility. This article first attempts to describe the tax system for company cars along with the specificities of the cars concerned. Next, this synopsis describes the characteristics of the companies which provide these cars and the profile of the employees who use them. An analysis of the distances travelled by company cars and their impact on road traffic is conducted, as well as an assessment of the impact of the system on taxes and salaries. Finally, a brief analysis of the environmental impact of company cars is carried out concerning the production of greenhouse gases as well as the impact of emissions on human health. The challenges and debates related to company cars in Brussels and in Belgium are put into perspective at the end of the article.
Skin Wounding–Induced Monocyte Expansion in Mice Is Not Abrogated by IL-1 Receptor 1 Deficiency
Authors: Barman Pijus K. , Pang Jingbo , Urao Norifumi , Koh Timothy J. 
Published: March 2019

Abstract
The aim of this study was to determine whether skin wounding induces monocyte (Mo) expansion in bone marrow and whether IL-1R1 signaling regulates this process. Our data show that skin wounding increases myeloid lineage–committed multipotent progenitors (MPP3 subset) and Mo in bone marrow, but this expansion is not impaired in Il1r1−/− mice. We also demonstrate that M-CSF–induced differentiation of myeloid progenitors into Mo is not impaired by the loss of IL-1R1 ex vivo, indicating that IL-R1 deficiency does not abrogate myeloid progenitor differentiation potential. In addition, we observed modestly delayed wound closure in Il1r1−/− mice associated with higher frequency of Ly6Clo Mo in the circulation at baseline and in wounds early after injury. Thus, in contrast to other models of inflammation that involve IL-1R1–dependent monopoiesis, our results demonstrate that skin wounding induces Mo progenitor and Mo expansion independently of IL-1R1 signaling.

Authors: Lima Carolina De Souza , Ruchkys Úrsula De Azevedo 
Published: March 2019

Ouro Preto tem bens reconhecidos como Patrimônio pela UNESCO o que lhe dá uma significativa projeção que fomenta o turismo, geralmente restrito a esses bens. Esta pesquisa propõe um método fundamentado na análise espacial e na quantificação de atrativos naturais relacionados ao geopatrimônio para os 12 distritos que integram o município. Para cada atrativo, são definidos valores sobre o potencial educativo e recreativo, além da quantificação do risco de degradação. Posteriormente, é feita uma interpolação considerando a intensidade e densidade das quantificações obtidas, o que resulta em cinco classes representantes do potencial geoturístico. Os resultados indicam que todos os distritos têm potencial para o geoturismo com destaque para Santo Antônio do Leite e Lavras Novas. Espera-se que esse estudo possa auxiliar no desenvolvimento do geoturismo na região.
Epidemiology of traumatic maxillofacial injuries in Queensland, Australia
Authors: S. Alsayad Fatima A. 
Published: March 2019

Maxillofacial injury, also called facial trauma, is a major public health problem, representing a group of injuries in which there is an external force that traumatically injures the face. They comprise hard tissue as well as soft tissue injuries that exhibit different patterns of clinical features based on the severity and mechanism of the trauma. Traumatic maxillofacial injuries not only are a leading cause of morbidity and mortality in Queensland, Australia, but also have negative effects on quality of life, functional status, and social functioning. Further, they have a range of economic impacts, including on health care costs, employability, productivity, and insurability. Thus, control, minimization, and prevention of traumatic maxillofacial injuries have immediate health effectiveness, and considerable economic benefits.

IntroductionObesity has become the most prevalent chronic disorder that affects large populations, particularly children, all over the world. Although the cause of obesity has largely been considered to be multifactorial, the concept of a viral origin has been relatively understudied, in comparison with genetic and behavioral causes. Emerging evidence supports adenovirus 36 (Ad 36) as a potential cause of human obesity. We aimed to examine whether Ad 36 infection is associated with obesity and lipid disorders in Egyptian children.Material and methodsOne hundred and thirty children and adolescents were included in this study; 80 of them were obese and 50 were controls. All participated in physical and clinical examination. Personal habits of nutrition, anthropometric measurements, and laboratory parameters including plasma glucose, insulin, HOMA-IR index, lipid profile and Ad 36-specific neutralizing antibodies were assessed.ResultsFood habit inquiries revealed that 70% of all children had snacks before lunch, which were significantly higher in carbohydrates and fats in obese subjects (p = 0.009). No significant difference in lipid profile was found between the 2 groups. Obese children had significantly higher levels of insulin and HOMA-IR index than the controls. Adenovirus 36 IgG was positive in only 2 of the obese children. Age was positively correlated with BAZ, insulin levels and HOMA index (r = 0.29, p < 0.001; r = 0.29, p = 0.001 and r = 0.22, p = 0.013, respectively). A positive correlation between insulin and BAZ (r = 0.24, p = 0.007) was found.ConclusionsNo association was found between obesity and infection with Ad 36 in Egyptian children, indicating that Ad 36 has a limited effect as a causative agent of obesity in the Egyptian community.
Puzzling Politics: A Methodology for Turning World-Systems Analysis Inside-Out
Authors: Gates Leslie C. , Deniz Mehmet 
Published: March 2019

Can world-systems analysis illuminate politics? Can it help explain why illiberal regimes, outsider parties, and anti-immigrant rhetoric seem to be on the rise? Can it help explain any such nationalchanges that seem destined to shift how nations relate to world markets? Leading surveys of historical sociology seem to say no. We disagree. While there are problems with Wallerstein’s early mode of analyzing politicsin the capitalist world-system from the outside-in, historical sociologists have been too quick to dismiss world-systems analysis. We propose an alternative inside-out approach anchored in a methodology for selecting what to study: those national political transformations which constitute puzzling instances within a given world-historical political process. We recommend promising theoretical lineages to guide empirical research on the selected puzzle: those that specify the elite social bases of politics. We thereby turn world-systems analysis inside-out. Our inside-out approach advances the project of world-systems analysis as a methodology, rather than a theoretical prescription in several ways. First, it addresses an important but largely overlooked question: how to select what to study. Second, it devises a methodology that can, but does not have to, pair with the methodology of incorporated comparisons. Third, it offers a methodology that stimulates, rather than forecloses, theoretical flexibility and fresh interpretations of politics and the world-economy. We illustrate the strengths of this new approach with three books, two of which won the best book award from ASA’s Political Economy of the World System (PEWS) Section.
From Carbon Democracy to Carbon Rebellion: Countering Petro-Hegemony on the Frontlines of Climate Justice
Authors: LeQuesne Theo 
Published: March 2019

This essay combines salient instances of climate justice activism in key battlegrounds against the fossil fuel industry in the United States and Canada with theoretical interventions in studies of corporate power, grassroots democracy, and counter hegemony. It explores Timothy Mitchell's Carbon Democracy and the term’s relevance to understanding the conditions in which climate justice activists must combat the entrenched interests of fossil fuel companies. It suggests that Carbon Democracy is a helpful concept for understanding how fossil fuel dependency both shapes and distorts democratic governance. Drawing upon insights in three case studies - activism against Chevron in Richmond California, the Water Protectors and the Dakota Access Pipeline at Standing Rock, and the First Nations-led fight against the Trans Mountain Pipeline in British Columbia - the essay supplements Carbon Democracy with two more terms: Petro-Hegemony and Carbon Rebellion. These reveal three power relations, namely consent, compliance, and coercion, upon which fossil fuel companies depend and in which climate justice activists must strategically intervene to move beyond conditions of Carbon Democracy. I show that dual power is a logic of strategic intervention that climate justice activists are successfully using to intervene in all three of these relations to reign in corporate power and assert their own sovereignty.
Development and Environment: Industrial Action in the Anthracite Region of Pennsylvania, 1947–1968
Authors: Straub Alexandra 
Published: March 2019

ABSTRACT
Coal mining is a historically dirty business, creating numerous environmental problems. This article examines the detrimental impact anthracite mining had on the environment of northeastern Pennsylvania and the involvement of local groups, specifically business interests, in their efforts to reverse the effects of mining in the post–World War II era. Despite a rich social and labor historiography of the anthracite coalfields, little has been written on the environmental aspects of the region. The traditional historical perspective is one of environmental degradation due to uncontrolled capitalism. These accounts largely ignore the environmental perspectives and reactions of local interests. Examining local involvement reveals a strong correlation between a healthy environment and economic progress that ultimately changed the environment of the area. Seen in this way, business and environmental interests in the anthracite region were two sides of the same coin.

Longitudinal Assessment of Medical Student Emotional Intelligence Over Preclinical Training
Authors: Mintle Linda S. , Greer Clark F. , Russo Lauren E. 
Published: March 2019

Abstract

Context
Given the importance of emotional intelligence (EI) in physician leadership and success, the possible decline of EI over the course of training is a concern in medical education.

Objectives
To assess the EI of osteopathic medical students as they progress through the preclinical years of medical school, to discover the course of EI over time, and to identify specific core EI competencies to be enhanced or coached.

Methods
This exploratory, longitudinal study used survey data to assess the course and competencies of EI in the incoming 2019 class of medical students at a college of osteopathic medicine. Changes in EI overall scores and the 8 core competency scale scores were assessed, and additional demographic data were collected for use in analysis. Methods of analysis included paired samples t test, independent samples t test, Pearson product moment correlation, and multiple regression analysis. Statistical significance was defined as P<.05.

Results
Sixty-two participants completed the Six Seconds Emotional Intelligence Assessment survey at orientation and again after their second year. Overall EI scores declined over the course of the preclinical training for men and women (t
6
1=4.24, P<.001), although no differences were noted by gender when independent-samples t tests were run. However, 2 of the 8 competency scales of the composite EI scores did not decline over time—Enhanced Emotional Literacy and Pursue Noble Goals. A weak negative correlation was found between Medical College Admission Test scores and the scale of Apply Consequential Thinking (r=−0.3, P<.05). A weak positive correlation was found between grade point average and intrinsic motivation (r=0.3, P<.05) and optimism (r=0.3, P<.05), and a moderate positive correlation existed between preboard examination scores and intrinsic motivation (r=0.5, P<.001) and optimism (r=0.4, P<.01). None of the chosen independent variables (academic grades, test scores, age, or gender) contributed to overall EI scores.

Conclusions
During the preclinical training, osteopathic medical students’ overall EI scores, as well as 6 of the 8 core competency scales, declined. Therefore, EI coaching is warranted to address specific core competencies needed to build, enhance, and prevent the decline of EI through preclinical training.

Published: March 2019

Colletotrichum destructivum was isolated from infected seeds and pods of cowpea (Var. IAR-48) with typical symptoms of anthracnose disease. The fungus during the pathogenesis, reduced the protein, fat, ash, crude fibre, carbohydrate, calcium and phosphorus, and increased the amount of iron, sodium, zinc, magnesium and potassium in the infected seed and husk. The carbohydrate, protein and phosphorus contents in the healthy husk reduced from 55.05%, 11.21% and 171.85 mg to 39.94%, 8.92% and 42.92 respectively in the infected sample whereas potassium and sodium contents in the healthy pod increased from 1.03 mg and 78.29 to 2.90 mg and 100.65 mg respectively in the infected husk. The potassium, sodium, magnesium and iron increased from 1292.25 mg, 0.19 mg, 0.09 mg and 11.00 mg in the healthy seeds to 1536.03 mg, 0.28 mg, 0.21 mg and 13.19 mg respectively in the infected seeds. The fungus caused the depletion of phosphorus from 498. 06 mg in the healthy to 430.17 mg in the infected seed, protein from 24.09% to 17.86%, carbohydrate from 57.02% to 34.35%, fat from 1.70% to 1.33% and crude fibre from 3.94% to 2.61%. The average loss of the major nutrient values; protein, carbohydrate and fat were 28.95% and 22.55% for seed and husk respectively after 8 weeks of planting.

Published: March 2019

Laboratory study was conducted to evaluate the effect of leaf extracts of five indigenous plant on conidia germination, growth and sporulation of Pseudoperenospora cubensis causing downy mildew disease of muskmelon. Extracts of five plant; mexican sunflower (Tithonia diversifolia), bush banana (Uvaria chamae), salt and oil tree (Cleistopholis patens), goat weed (Ageratum conyzoides) and African eggplant (Solanum macrocarpon) at Four concentrations (15, 30, 45 and 60%) were tested against the growth, conidial germination and sporulation of Pseudoperenospora cubensis in vitro.
Results show that all the plant extracts significantly inhibited conidia germination and radial growth compared to the control. The extracts had no significant (p≤0.05) effect on sporulation. The rate of inhibition of growth and conidia germination was concentration dependent being highest at 60% for the extracts. The extracts of Solanum macrocarpon was the most effective followed by Ageratum conyzoides, Cleistopholis patens and Uvaria chamea whileTithonia diversifolia caused the least inhibition of growth and conidia germination. At 15, 30, 45 and 60% concentrations growth of Pseudoperenospora cubensis on PDA modified with Solanum macrocqrponwere 3.79, 3.65, 3.33 and 2.87; and 4.25, 4.12, 3.92 and 3.89 for PDA modified with Tithonia diversifolia. Similarly, conidia germination percentages recorded at same concentration of extracts S. macrocarpon were 87, 85, 70 and 62% while that of T. diversifolia were 91, 87, 84 and 72%. The study shows that the plant extracts has the potential for inhibition of the pathogen.

Authors: Ngwa N. N. , Nnam N. M. 
Published: March 2019

Aims: To correlate obesity/atherosclerosis with body mass index, serum cholesterol, serum triglyceride, serum low density lipoprotein and serum high density lipoprotein of diet induced obese wistar rats.
Study Design: Department of Home Science, Nutrition and Dietetics (Animal research house) and Department of veterinary science both in University of Nigeria Nsukka. The study was conducted between January to March 2012.
Methodology: Four groups of twenty male Wistar rats were fed a highly palatable diet for 2 weeks to induce obesity resembling mild obesity condition in human population after one week acclimatization period. DIO rats received rat chow and flavonoids extract daily for 6 weeks. Group 1 received rat chow alone; Group 2- 0.05% of flavonoids extract and rat chow; Group 3- 0.15% of flavonoid extract and rat chow; and Group 4- 0.25% of flavonoid extract and rat chow. BMI, Total cholesterol, HDL, LDL and Triglyceride were evaluated using standard assay technique. The data were statistically analyzed using ANOVA and mean separated using LSD.
Results: Feeding the rats with palatable diet showed increased in BMI (from 0.35-0.40 to 0.60-0.65), total cholesterol, LDL and triglyceride levels along with decrease in HDL (p<0.05). Consumption of flavonoids resulted in the significant reduction in BMI, LDL, total cholesterol and triglyceride level and exhibit significant elevation in HDL cholesterol compared to the rats fed only rat chow (p<0.05). It was observed that the decrease in BMI, Triglyceride, total cholesterol and LDL cholesterol level of rats fed 0.25% of flavonoids were significantly different (p<0.05) from those fed 0.15% and 0.05% flavonoids.
Conclusions: The results suggest that flavonoids extract from Solanum macranthum has atherogenic effect which can help to reduce obesity.
