Les déterminants technologiques de la persévérance des étudiants dans les cours à distance de niveau collégial : Les modalités de cours jouent-elles un rôle?
Authors: Lakhal Sawsen 
Published: October 2019

L’objectif de cette étude est d’identifier et d’analyser les déterminants technologiques de la persévérance dans les cours à distance de niveau collégial (n=61), issus du modèle Unified theory of acceptance and use of technology (UTAUT). Les résultats des analyses par équations structurelles (Partial Least Square) indiquent que parmi ces derniers déterminants, seulement les conditions facilitantes ont un impact significatif et positif sur l’intention comportementale d’utiliser les technologies des cours à distance (R2=54%) définie comme l’intention de l’étudiant de réaliser ce comportement, qui a son tour a un effet significatif et positif sur la persévérance, définie par l’intention de finir le cours à distance auquel l’étudiant est inscrit (R2=14,2%) et par l’intention de s’inscrire dans le futur dans d’autres cours à distance (R2=65%). Les analyses des ANOVA font ressortir des différences significatives entre les groupes d’étudiants assignés à des modalités différentes de cours à distance sur tous les facteurs technologiques laissant présager que des analyses différenciées, selon la modalité de cours, devraient être envisagées dans le futur.
This study aims to identify and analyze the technological determinants of persistence in college distance education courses (N=61), derived from the Unified theory of acceptance and use of technology (UTAUT) model. The results of the structural equation analyses (Partial Least Square) revealed that among these determinants, only facilitating conditions have a significant and positive impact on the behavioural intention to use distance learning technologies (R2 = 54%) defined as the student’s intention to display this behaviour. Moreover, behavioral intention to use distance learning technologies has a significant and positive effect on persistence, defined as the intention to finish the distance education course in which the student is enrolled (R2 = 14.2 %) and the intention to enroll in other distance education courses in the future (R2 = 65%). The ANOVA analyses revealed significant differences between the groups of students assigned to different courses delivery modes on all the technological factors, suggesting that differentiated analyses, depending on the course delivery mode, should be performed in the future.

Au 21e siècle, l'acquisition de compétences numériques est importante afin de rester à jour avec les avancements technologiques qui affectent la vie quotidienne. Cherchant à mieux comprendre l'acquisition des compétences numériques, ce projet de recherche vise les environnements d’apprentissage riches en technologies, plus précisément les laboratoires de fabrication numérique. Nous avons réalisé une étude de cas multiples dans 4 écoles dans la province canadienne du Nouveau‑Brunswick (N.-B.) où nous avons capturé un total de 23 vidéos d’élèves au travail dans des laboratoires de fabrication numérique. Les résultats démontrent que la pensée critique, la créativité, la collaboration, la communication et la résolution de problèmes sont mises en évidence dans les laboratoires de fabrication numérique.
In the 21st century, many school systems are turning to the development of skills as an educational goal, including digital skills. However, the current scientific literature on digital skills remains insufficient, both in terms of their definition and the processes of their development. Our research project aims to examine the presence of digital skills in learning environments that are considered technology-rich, specifically makerspaces. We conducted a multiple case study in three schools in New Brunswick where we observed students in the process of working on a project in a makerspace setting, and our analysis focused on the digital skills demonstrated. The results suggest that the type of activities that young people do in a makerspace, as well their age and the time they spend in the makerspace, can all influence the development of digital skills.

Background:Metabolic syndrome worsens complications in psoriasis patients by predisposing them to cardiovascular diseases. Psoriasis has been widely associated with metabolic syndrome; however, it has still not been proven owing to a limited number of studies and some of those reporting conflicting results.Objective:Psoriasis has reportedly been associated with metabolic syndrome; however, it has yet not been established beyond doubt owing to conflicting literature. The present meta-analysis of observational studies aims to evaluate the prevalence of metabolic syndrome in psoriasis patients and establish an inferring point that psoriasis patients are certainly susceptible to metabolic syndrome. The study will benefit clinicians to assess and monitor psoriasis patients for several associated comorbid conditions and in its treatment.Methods:A systematic web search for ‘Psoriasis’, ‘Metabolic Syndrome’, ‘Hypertension’, ‘Plasma Glucose’, ‘Dyslipidaemia’, ‘Waist Circumference’ was performed, collecting all original observational studies on humans up to April 30, 2018. Depending on the inclusion and exclusion criteria, articles were screened for eligibility. Due to the presence of significant heterogeneity, the Odds Ratio (OR) was calculated using a random-effect model with Der-Simonian and Laird method. The statistical heterogeneity was determined using I2 statistics. Comprehensive Meta-Analysis Software, Version 3 was used to perform all the analysis.Results:Sixty-three studies encompassing 15,939 psoriasis patients and 103,984 controls were included in this meta-analysis. Among them, 30.29 % of psoriasis patients were reported with metabolic syndrome in comparison to 21.70 % of subjects in the control group. The present study clearly indicates an increased prevalence of metabolic syndrome among psoriasis patients (OR: 2.077 [95% CI, 1.84 - 2.34]).Conclusions:The findings support the fact that psoriasis patients have a higher incidence of metabolic syndrome. Our study also recommends that psoriasis patients should be regularly monitored for metabolic syndrome complications and its associated risk factors such as hypertension, raised triglyceride, lowered HDL Cholesterol, increased fasting plasma glucose, and waist circumference.

Published: October 2019

Ralstonia solanacearum is a plant pathogen causes wilting which is a major obstacle in the cultivation of tomato plants. In plant breeding, knowledge of the source of resistance genes and inheritance patterns is important in the development of bacterial wilt resistant varieties. This study aimed to obtain bacterial wilt resistant lines and to find out the inheritance pattern of tomato resistance to bacterial wilt. Selection of resistant plant involved the selected breeding lines from irradiation and crossing collections of the Genetic Laboratory, Faculty of Agriculture, Universitas Gadjah Mada. Introduced lines of H-7996 and F1 Permata and Timoti were used as a control. H-7996 as resistant parents and GM2 as susceptible parents, and their offspring include F1 GM2 x H-7996, F1 reciprocal, F2, Back Cross 1 (F1 x GM2), and Back Cross 2 (F1 x H-7996) used in testing inheritance patterns. Inoculation was carried out 1 week after planting by pouring 100 ml of water suspension of R. solanacarum (108 cfu/ml) on the roots. Completely Randomized Design (CRD) was used in this experiment. The scoring observation was carried out every week for one month. This study showed that Permata as a control was the most resistant, while Timoti and H-7996 were medium resistant. The CLN, G6, G8, and G7 lines were susceptible medium, yet only G8 and G7 with the smallest percentage of disease intensity and not significantly different than Timoti. The resistance gene to bacterial wilt on H-7996 was controlled by genes in the cell nucleus with additive-dominant gene action. Resistance to bacteria has a moderate level of heritability.
UNDERWRITING PERFORMANCE SHOCKS IN THE NON-LIFE NIGERIAN INSURANCE INDUSTRY AND MACROECONOMIC RISKS: A VECTOR AUTO REGRESSIVE APPROACH
Authors: Onafalujo Akinwunmi Kunle 
Published: October 2019

Insurance company’s performance can be stymied by internal and external risks. Industry reports show 23 companies out of the 55 operating companies (about 42%) in Nigeria recorded net operating losses in 2015. Macroeconomic risks are external and may be quite significant in providing an (un)favourable environment for performance of the industry particularly in a developing economy like Nigeria. Reflecting on the contribution of insurance to the Nigerian economy which shows an abysmally low penetration, averaging below one percent of GDP when compared to African peers such as South Africa at 13% and Kenya above two percent; it is of essence to investigate how these risks affect its performance which by implication could adversely affect insurance penetration. Dynamic least square regression technique was employed to study the dynamics of macroeconomic risks (GDP, inflation rate, and interest rate) on underwriting performance over the period 1981-2015. Weighed against theoretical underpinnings and other studies particularly in western economies, the study has evidence that interest and inflation rate shock adversely underwriting performance. Also, real GDP does not have positive shock on premium growth and loss ratio. Monetary policy should address inflation, and interest rates if the underwriting performance shocks in the non-life sector are to be mitigated in Nigeria. In the long term, government should focus on how to improve income per capita and reduce income inequality and dependency ratio so as to connect insurance consumption to real GDP growth.

Известно, что для улучшения эксплуатационных характеристик металлических изделий широко применяются наплавки, в частности плазменные. В работе исследовалась плазменная наплавка из медно-никелевого сплава, нанесенная на стальную цилиндрическую поверхность. К наплавкам предъявляются повышенные требования: стабильность толщины покрытия, отсутствие макроскопических дефектов в виде трещин и непроваров как в толще наплавки, так и в зоне сплавления.Учитывая, что акустические свойства медно-никелевой наплавки и основного металла близки по своим характеристикам, обеспечить контроль качества наплавки существующими методиками (на базе акустических методов) достаточно сложно, особенно в условиях массового производства. В связи с этим возникает необходимость дальнейшего развития существующих методов и методик контроля толщины наплавок, акустические свойства которых близки к свойствам основного металла.Для решения данной проблемы были проведены исследования, которые показали, что можно использовать наклонный преобразователь поперечных волн с углом ввода, обеспечивающим контроль заданной толщины покрытия с погрешностью 0,02 мм. Экспериментальные данные, полученные акустическим методом, подтверждены результатами химического травления. Также по результатам этих исследований предложен автоматический контроль толщины покрытия с выводом результатов контроля в базу данных и на экран монитора.
The Poetics Of A Multiphonic Landscape
Authors: Torben Snekkestad  
Published: October 2019

The project is an artistic research project focusing on the saxophone􏰁s ability to produce multiphonics (multiple sounds on an instrument considered monophonic). It is a personal artistic exploration into the process of unfolding the poetics of these complex sonics and a reflection over the process, methods and the creation of an album trilogy, consisting of acoustic solo music recorded during the research period.

The main question I have been asking myself during this project has been:

What happens if the raw musical material, in the creation of a set of solo saxophone works, is based on the multiphonics only and what this material in itself suggest – possibly independent of any stylistic affiliation?

My main objective was to examine why the saxophone’s multiphonics have such a captivating effect on me. How could I possibly explore their intrinsic qualities and unfold the poetic potential in them? By the same token, my ambition was to find a suitable artistic context for this enamored relationship that so heavily has stirred the waves of my imagination.

In the reflection text on the project, I disclose how some unexpected paths during this pursuit revealed themselves. From sprouting interest toward underwater soundscapes, to the making of a hybrid instrument called reed-trumpet; and how my personal catalog of multiple sounds found its place, not in a public pdf-document or book release, but in a German wooden archive box.

I relay in what way I began to take on the intrinsic qualities of the multiphonics and the reason why an oscillation between artistic intention and action is so pivotal for an improviser. To make sure that the project had this focus at all time I sat up a dogma that contains a list of eight fundamental criteria that manifest the intentions and structure as well as sharpen the working methods.

On Soft Metric Spaces
Authors: Hassan Radwa mohamed 
Published: October 2019

After the famous article of Moldotsove [10] in 1999 which initiate the theory of soft sets as a mathematical theory to deal with the uncertainty problems, many research works in the softbmathematics and its applications in various fields are appeared. In [17], the authers introduced a new definition of the soft metric function using the soft elements. By this definition each soft metric in view of Das and Samanta [6] is also a soft metric in our concept but the converse is not true. In the present paper, some soft topological properties are given in details, namely (soft compactness, soft sequentially compactness, continuity and uniformly continues of soft functions between soft topological spaces). We hope that the findings in thispaper will help researcher enhance and promote the further study on soft topology to carry out a general framework for theirapplications in practical life.

Published: October 2019

Abstract
The quest for new sources of financing for the development of green economy sectors and enterprises is one of the challenges to effective management. This study verifies whether a relationship exists between the activity of selected companies who access the capital market in search for new financing sources, their development level and their competitive edge. The sample used in this study was composed of companies from the forestry and wood-based sector (a major part of the Polish economy) listed on the Warsaw Stock Exchange. The Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) was used to assess the development level of selected enterprises. The main recommendations were formulated based on the findings from the analysis of performance ratios and from the comparative and descriptive analysis of data on stock exchange transactions in the wood-based sector. This is because the assumption was made that by becoming more active in the capital market and, as a consequence, by strengthening their competitive position, the enterprises covered by this study may contribute to adding value in the circular economy.

Management of the Spare Parts Storage in the Production Process Using the Monte Carlo Method
Authors: Ślaski Paweł 
Published: October 2019

Abstract
The article presents the methodology of controlling stock of spare parts during short-run production of current equipment. A pseudo-random number generator has been developed, whose main task is to estimate the expected value E (Y) of the random variable Y which is the number of exchanges of a spare part of a particular equipment. By means of a Monte Carlo computer simulation, pseudo-random numbers are generated with a uniform distribution from the interval (0.1). These numbers, based on the cumulative distribution inversion method, are transformed into a form of distribution that uniquely determines the optimal size of spare parts
Advantages of Colour Etching in Quality Control of Recycled Al-Si Cast Alloys

Published: October 2019

Abstract
Colour Metallography is a set of light metallographic microscopy methodologies that utilize phase colour contrast as a source of new structure information compared to conventional techniques. In many cases, colour contrast can be induced where no identifiable phase contrast is obtained by conventional techniques. With the help of colour contrast, we gain new information on the structure of Al-Si alloys, especially intermetallic phases, in which the benefits of its use in casting quality control are of benefit.
Blue-yellow contrast is definitely more pronounced than dark grey or light grey contrast. There is no substantial reproducible colour reproduction, since it is irrelevant whether the two phases are distinguished by blue-yellow or green-ocher contrast. When using the colour contrast, the structural components differ not only according to their microscopic appearance, but also based on the knowledge of the chemical composition of alloys, interactions between structural components, knowledge of the possible influence of Al-alloys structure (e.g. refining, modifications, heat treatment).
Colour contrast in quality control of Al-Si alloys was applied to AlSiMg cast alloy (AlSi7Mg0.3; AlSi7MgTi; AlSi10MgMn; etc.)
