L’approche narrative collective : conversations en échafaudage pour l’intégration identitaire des étudiants en entrepreneuriat social et durable
Authors: Solbreux Julie , Hermans Julie , Pondeville Sophie
Published: October 2022

Cet article invite à découvrir l’approche narrative collective comme éclairage de nos pratiques d’enseignements en entrepreneuriat social et durable. L’objectif pédagogique majeur du dispositif vise à développer la capacité des étudiants à intégrer leur identité : faire du lien entre soi - son individualité complexe riche de ses valeurs et de ses intentions ; les autres - ses équipiers, dans l’échange et l’interaction des travaux de groupe ; et le reste du monde - l’environnement où s’inscrivent ses actions avec l’intention d’y produire un impact. Par l’utilisation d’histoires, de métaphores et d’objets flottants tel que le photolangage, les participants co-construisent des interprétations communes, riches et inclusives. Elles portent sur des moments d’exceptions où le groupe prend conscience et confiance en ses ressources et sa capacité à faire face aux défis sociaux et environnementaux qui l’entourent.

Quand la sexualité ne suffit plus à se démarquer : les démocrates LGBTQ+ à New York au temps de la « Resistance » anti-Trump
Authors: Bouvard Hugo , Thomas-Hébert Charlotte
Published: October 2022

Dans un champ politique devenu plus concurrentiel, l’orientation sexuelle ne constitue plus autant qu’avant un marqueur de distinction : désormais les candidat·es LGBTQ+ mettent en avant une multiplicité de capitaux corporels identitaires (jeunesse, racialisation, identité de genre marginalisée, etc.). Hugo Bouvard et Charlotte Thomas-Hébert mettent en évidence ces nouvelles ressources dans la compétition au sein du Parti démocrate en comparant les profils du personnel politique LGBTQ+ avant et après l’accession de Trump à la présidence en 2017.
Présidence Biden : l’ère des périls pour la gauche et le mouvement social
Authors: Magnaudeix Mathieu
Published: October 2022

La gauche états-unienne, en pleine ébullition sous Trump grâce à la puissance des mouvements activistes organisés, se retrouve (temporairement ?) pétrifiée sous la présidence Biden : en cause, l’immobilisme et le conservatisme des Démocrates, la prééminence d’institutions non démocratiques comme le Sénat et la Cour Suprême, mais aussi sa propre difficulté à mobiliser.
Statistical analysis of numerical solutions to constrained phase separation problems
Authors: Barg Michael , Mangum Amanda
Published: October 2022

We compute numerical solutions to a linearly constrained phase separation problem and a nonlinearly constrained phase separation problem on compact surfaces. Results are presented for oblate and prolate ellipsoids and Cassinian ovals. We implement a finite element, phase field method to determine solutions in the form of patches that are approximately geodesic disks for some values of the parameters. Our patches are numerical solutions to diffuse interface problems, and they exhibit qualitative features of solutions to corresponding sharp interface problems that are often studied in a $ \Gamma $-convergence setting. Our use of a nonlinear conservation constraint is motivated by a desire to sharpen the interface between two distinct regions: the patch and the rest of the surface. To this end, we explore features of the patches arising in both problems. A "geodesic protocol" is implemented to generate various statistics concerning the patch that are useful for measuring patch deviation from a geodesic disk shape. We then perform the Student's $ t $-test on paired differences of these statistics to determine whether or not there is a significant statistical difference between the linear constraint and nonlinear constraint approaches. The novel use of statistical analysis to compare these two methods reveals noteworthy differences. We show that the two approaches yield significantly different results for some of the statistics. The statistical results are found to depend on both the type of geometry and the patch size in some situations. Small patches are difficult to compute numerically, but we find that the use of a nonlinear constraint aids in their computation.
Analysis of horizontally polarized shear waves on a highly inhomogeneous loaded bi-material plate
Authors: Helmi Maha M. , Mubaraki Ali M. , Nuruddeen Rahmatullah Ibrahim
Published: October 2022

The current manuscript critically examines the propagation of horizontally polarized shear waves on the dispersion of a highly inhomogeneous thin bonded bi-material plate when a load due to the Winkler's elastic foundation is prescribed. An analytical procedure of solution is deployed for the study; in addition to the exploitation of effective boundary conditions approach for the asymptotic examination. The overall inference of the current study is the realization of the fact that the vibrational displacements in both layers are enhanced by an increase in the inhomogeneity parameter; at the same time lessened with an increment in the foundation parameter. Moreover, a perfect approximation of the dispersion relation has been realized, with its validity extending to almost the entire low-frequency range. Lastly, the influence of the material inhomogeneity has been noted to affect fundamental mode, as against the presence of the foundation parameter which affects the first harmonic curve. More so, an increase in the two parameters narrows the chances of low-frequency propagation.
Ćirić type nonunique fixed point theorems in the frame of fuzzy metric spaces
Authors: Došenović Tatjana , Rakić Dušan , Radenović Stojan , Carić Biljana
Published: October 2022

The paper defines a new contractive condition within $ \kappa- $orbitally complete fuzzy metric spaces $ (\Theta, \mathcal{M}, \mathcal{T}) $, as well as fixed point theorems for single-valued and multi-valued function on $ \Theta $ which is not necessarily continuous. The contractive condition is motivated by an idea proposed in Ćirić's paper "On some maps with a nonunique fixed points". Continuity of mapping $ \kappa $ is replaced by $ \kappa- $orbitally continuity property which provides the existence of the fixed point, but not necessarily uniqueness.
The Extended Technology Acceptance Model (ETAM): Examining Students’ Acceptance of Online Learning During COVID-19 Pandemic
Authors: Al Breiki Musabah , Al-Abri Abdullah
Published: October 2022

This study contributes to the existing literature on online learning during COVID-19 pandemic in higher education by investigating the relationships between the cognitive variables and students' adoption of online learning. Based on Technology Acceptance Model (TAM), some hypotheses we formulated to test the links between TAM constructs and online learning anxiety as an antecedent. This study adopted structural equation modeling (SEM) to scrutinize technology adoption for a sample of 569 students in Oman. The results indicated that attitude towards online learning is a strong predictor of technology adoption during COVID-19 pandemic. Furthermore, both the perceived usefulness of online learning and perceived ease of online use yielded a significant contribution of attitude. Besides, online learning anxiety affected both the perceived usefulness and perceived ease of online use negatively where perceived ease of use is predicted largely while perceived usefulness is predicted modestly. In the light of the previous findings, some recommendations and implications are provided.

Published: October 2022

Abstract—The article describes an integrated art and English project for specific purposes on the topic “Academic Conferences” used for teaching future Ukrainian engineers in the winter of 2022. The project finished right before the war in Ukraine began. The sample size included 90 third-course future chemical engineers who study English for specific purposes. This study investigated the benefits of the project for future engineers, the role of the art practices used, as well as students’ perceptions of the project. Online questionnaires, observations and interviews were used.  The results showed that the project improved students’ confidence in different conference-related skills and had a positive influence on the professional language skills development of future engineers. Art practices used in the project made learning memorable, contextualised and authentic. Art-related activities promoted professional communication and fostered the use of 21st-century skills such as cooperative, creative, critical and digital skills. The main hypothesis was supported and the project was effective due to the combination of project-based learning, art enhancement and integration, and specially chosen job-related art and ESP connections. The findings indicate an overwhelmingly positive response from the learners about this project and their interest in future art and ESP integrated projects. However, the study also revealed that students need additional support for developing XX cooperative, time management and writing skills as well as for working with authentic materials.

Authors: Jia Yufeng , Zhao Qi
Published: October 2022

The Learning Behavior Analysis (LBA) of students is a major function provided by most online education platforms. Based on the results of LBA, students can get customized learning path and recommended learning resources that suit their own situations, which can help them plan their individual training programs of Online Vocational Education (OVE). At first, this paper studied the resource recommendation algorithm based on the modelling of students’ online learning behavior sequences, and solved the problem of conventional learning resource recommendation algorithms of ignoring the dynamic changes in students’ learning preferences. Then, this paper presented the process of LBA applicable for OVE students, and gave a diagram of the flow of using big data to perform LBA. After that, this paper developed a bidirectional encoder based on self-attention model, and described the co-occurrence characteristics and dependencies of students’ online learning behavior sequences. At last, the model pre-training and fine-tuning processes were introduced in detail, and the experimental results verified the effectiveness of the proposed analysis and recommendation methods.

Authors: Ren Zibei
Published: October 2022

The Supply Chain Management (SCM) of agricultural products (AP) is an important part of modern logistics, and cultivating talents with rich theoretical knowledge and practical operation skills of the SCM of agricultural products is particularly meaningful for China as a major agricultural country. However, at present, few studies have concerned about the training path for such talents, so to fill in this research blank, this paper studied the training path for AP-SCM talents and the assessment of their training quality, aiming to find and solve the defects in the existing training programs. At first, this paper proposed training path for AP-SCM talents and attained the conclusion that colleges and universities should pose requirements for AP-SCM talents from 9 training directions. Then, a prediction model was built for assessing the training quality of AP-SCM talents, and the specific model framework and modeling principles were given. At last, experimental results verified the effectiveness of the prediction made by the proposed model.
Establishment and Study of an Evaluation Model for the Exploitation Effect of University Scientific and Technological Patents
Authors: Zhou Renguo
Published: October 2022

Due to the lack of sufficient understanding by the public of the process and mechanism of how university patents are exploited, the exploitation effect of university patents is not satisfactory. Therefore, it is necessary to effectively evaluate the exploitation effect of university patents in order to explore a reasonable path for and expand the role of university patent exploitation. Currently, there has been few research on how to evaluate the exploitation effect of university patents. To this end, this paper focuses on university scientific and technological patents and explores the effective evaluation method for the exploitation effect of these patents. First, market share, market benefit, patented technology maturity, enterprise nature and government support were selected as the evaluation indicators for the exploitation effect of the scientific and technological patents in colleges and universities in the study area. It was proposed that the five influencing factors and the exploitation effect of university scientific and technological patents interact with and influence each other. Then a combined model based on grey prediction GM (1,1) model and BP neural network model was constructed for the evaluation of the exploitation effect of scientific and technological patents in colleges and universities, which proved to have better prediction performance. The experimental results proved the effectiveness of the prediction model, and also verified the interactions between the five influencing factors and the exploitation effect of university scientific and technological patents.

Authors: Wang Na , Dai Bing , Pei Chunyan , Zhang Yujie
Published: October 2022

Data mining of the mobile learning behavior of learners can help researchers understand the underlying association rules of such behavior and the internal mechanism of the development of their thinking during the learning process, thereby giving the true and accurate evaluations on the thought and status of mobile learners. However, existing models established for mobile learning behavior recognition cannot give satisfactory enough explanations to the changes in the cognition level of learners, so this paper took employees in accounting profession as subjects to analyze the features and influencing factors of their mobile learning behavior. At first, this paper built a neural network model based on the attention mechanism and used it to classify and recognize the input data of mobile learning behavior via original data learning, and feature extraction and analysis. Then, this paper created evaluation scenarios for subjects participating in mobile learning, designed economic management tasks applicable for actual application scenarios, and proposed several evaluation indexes for assessing their learning performance. After that, the explicit learning behavior of the subjects was taken as the criterion for judging whether their learning performance has achieved the desired learning goals or not. At last, the effectiveness of our analysis model was verified by the experimental results.
La production de l’exception : discipline et sacralisation de la parole dans les couvents féminins post-tridentins
Authors: Roullet Antoine
Published: October 2022

Cet article examine les contraintes qui pèsent sur la circulation de l’information et de la parole dans des couvents féminins de l’époque tridentine, en particulier chez les carmélites déchaussées, à partir de la manière dont elle est dévotement lise en scène dans les hagiographies des religieuses. Il s’agit moins de mettre en évidence une répression de la parole, selon le poncif qui voudrait que les couvents soient exclusivement des lieux de silence qu’une discipline, circonstanciée, précise, englobante, qui tente de réguler jusqu’aux espaces et aux temps de la récréation dont le propos est de légitimer certaines paroles au détriment d’autres et de dessiner un espace de parole ordonné. En posant qua la prise de parole est l’exception, même si celle-ci est de fait fréquente, les normes conventuelles et l’usage que les religieuses savent en faire permettent l’émergence d’une parole sacralisée qui raffermit l’autorité des supérieures et espère réguler la vie communautaire
Callisto et Arcas, ou la maternité inaccomplie de l’ourse
Authors: Scaccuto Alessandra
Published: October 2022

Cet article vise à étudier les intersections entre genre, animaux et animalité dans le mythe grec antique de Callisto et Arcas, tel qu’il est raconté par plusieurs textes grecs et latins, dont Ovide, qui est la source privilégiée de notre enquête. Le mythe est analysé à la lumière des représentations et des significations symboliques que les cultures grecque et romaine associaient à l’animal en question, l’ourse, et plus particulièrement à sa maternité, afin de voir si certaines des caractéristiques qui lui sont attribuées dans la zoologie ancienne peuvent offrir de nouvelles pistes de compréhension du mythe de Callisto. La plasticité habituelle des mythes anciens se mélange, en effet, à la polysémie de la figure de l’ourse-mère, donnant ainsi lieu à des versions différentes du même mythe, qui partagent tout de même une caractéristique. En effet, la mère et l’enfant sont toujours séparés : par conséquent, l’histoire de Callisto et d’Arcas se configure comme une histoire de maternité inaccomplie.

Establishing a Student Research Day
Authors: Marchese Megan Margino
Published: October 2022

To develop Farmingdale State College's first interdisciplinary research event, the library collaborated with several campus departments to establish Student Research Day. Inspired by its acquisition of a poster printer, the library proposed the implementation of a student poster session, sought out campus partnerships to garner student involvement, and secured event funding through a campus grant. Specifically, the library formed a strong partnership with the Research Aligned Mentorship (RAM) Program. This program provides extra benefits and research opportunities to students who are selected from a lottery of minority, low income, and/or first-generation college students. Through its collaboration with the RAM Program, the library facilitated specialized instruction, assessed students' confidence levels in conducting research, and successfully hosted a large-scale research event, the first of its kind at the college.
Asset Mapping in Academic Libraries
Authors: Wegner Alia Levar , Henle Alea
Published: October 2022

Miami University Libraries harnessed the power of asset mapping to create and manage eight remote digital projects during the COVID-19 pandemic, drawing on library staff and students from across the university. This chapter documents the steps and actions and offers insights into techniques and approaches that may be adopted under different circumstances. Asset mapping facilitated matching available staff and skills with available projects and resulted in a dramatic increase in productivity. Properly deploying asset mapping involves identifying ways to provide benefit to all involved parties. Special collections used the quarantine to jumpstart alliances with other departments, who provided staff time, skill, and labor, but the initiative's success is demonstrated not merely by productivity during quarantine but staff interest in maintaining a degree of involvement afterward.

Authors: Al-Sabaawi Mohmed Y. Mohmed , Alyouzbaky Bassam A.
Published: October 2022

Understanding the effects of information technology infrastructure flexibility (ITIF) and behavioural biases on investment decisions will help investors make more informed choices. Due to a lack of investment and decision-maker biases, Iraqi universities' IT infrastructure is not well developed, resulting in low performance. However, few studies look into the causes of this phenomenon. This study aimed to investigate the impact of ITIF and behavioural biases on investment decision making and their impact on organisations' performance. A total of 209 valid responses from decision-makers in private universities of the Republic of Iraq are analyzed. A set of statistical analyzes are performed with SmartPLS software. The results show that there is a significant impact of ITIF factors and behavioural biases on investment decision making. Also, investment decision making influences organizational performance. The research confirms the significance of ITIF and behavioural biases as critical indicators of organizational strategic decision making.

Authors: Wu Xinli , Chang Jie , Lian Fei , Jiang Liheng , Liu Juntong , Yasrab Robail
Published: October 2022

The rapid development of big data technology has attracted a variety of sectors, including tertiary education. The purpose of this paper is to construct a precision teaching mode based on big data technology in order to improve teaching quality and further promote education and teaching reform. The proposed mode, based on the theory of precision teaching in colleges and universities as well as the intrinsic properties of big data teaching activities, describes five procedures for analyzing learning situations, determining teaching goals, preparing teachers, and evaluating teachers. When the big data-based precision teaching mode is applied to the “Python Language Programming” course, the results show that students are more satisfied with the design of the teaching and more efficient in learning. It is believed that this mode will significantly improve students' academic performance and their ability to work independently and collaboratively as a result of more frequently online and offline interactions between teachers and students.
Prediction of the Flattening Ratio and Hardness of Cold Sprayed Deposits
Authors: Sharma Mala M. , Wolff Francis L. , Eden Timothy J. , Champagne Victor K.
Published: October 2022

Cold spray technology is a solid-state deposition process where solid particles are accelerated to very high velocities by expanding a compressed gas through a supersonic nozzle. The particles impact a substrate located approximately 25 mm from the exit plane of the nozzle. Predicting the deformation and resultant properties helps in developing process parameters and tailoring coatings to get the desired properties. In this study, aluminum, copper, and nickel coatings were produced using a range of process parameters that produced different particle impact velocities. The Hollomon power law relationship and Johnson-Cook flow stress model were utilized to predict the hardness of cold spray coatings. Results showed there was good agreement between the predicted and measured hardness of the respective coatings. Additionally, a methodology was developed to measure deformation in the form of a flattening ratio of the deposited particles. There was good agreement between the predicted and measured flattening ratio, especially for the Al and Ni feedstock powders.

Authors: Ravaszová Simona , Dvořák Karel
Published: October 2022

The article deals with the laboratory preparation of clinker mineral belite. It monitors the stability of β-C2S with respect to the firing regime and the effect of the stabilizing additive H3BO3. Belite was prepared by high-speed milling using solid-state reaction at 1150, 1250, 1350 and 1450 °C with 30 min soaking. It deals in more detail with the higher temperature 1450 °C where it compares the content of individual phases of belite with samples prepared without the stabilizer H3BO3. The results showed a significant stabilizing effect of boron at a higher firing temperature. The effect of the stabilizer is more pronounced in firing regimes, where γ-C2S is more readily formed, especially at firing temperature 1450 °C with 0, 30, 60 and 90 min soaking. In the samples with the stabilizing additive, double the amount of β-C2S was identified in comparison with the samples prepared without the stabilizer. At a temperature of 1450 °C and 90 minutes, almost 100% β-C2S was prepared using a stabilizer H3BO3.

Published: October 2022

With energy demand and for promoting the energy supply to remote areas the fuel from biomass initiative is carried. Gasification technology is an efficient conversion technique for biomass resources to energy. The production of producer gas by gasification are used for various applications including electricity generation. Utilization of the Producer gas for applications involves the flow of gas through pipes from reactor to applications. During the flow, the producer gas is subjected to wet scrubbers and passes through various filters for gas clean-up. The pipelines suffer corrosion due to moisture deposits and chemical components in the Producer gas. In this paper, the influence of producer gas to the inner surface of pipelines in downdraft gasifiers is investigated. The inlet pipe exhibits reduction ranging 68 to 72 HRB in the hardness comparing to the outlet pipe ranging 77 to 78 HRB from the coarse filters.

Authors: Patil Pradip V. , Kale Rajendra D.
Published: October 2022

Aluminum Oxide thin films are potential candidate for anti-reflection, anti-soiling, and self-cleaning applications for solar cell panels, solar water heating panels, exterior windows of buildings, glasses, car windows, fabrics, and clothes. This paper reports on effect of chopping during deposition on the intrinsic stress and adhesion of Al2O3thin films deposited by electron beam evaporation. The kinetics of the growth and structure of the thin films is governed by adhesion. The durability and its wear are related to the certain extent adhesion of the thin film to the substrate. Effect of ambient aging on the adhesion and the internal stress in the films are also reported. The effect of chopping the thin film growth, phase change and presence of Al2O3 studied using scanning electron microscopy (SEM) and x-ray diffraction (XRD). The accumulation of strain energy in the thin film appears as internal stress and the binding of the vapor atoms to the substrates is referred to as adhesion. In this work, adhesion of thin films measured by direct pull off method and the internal stress is measured by interferometric method.
Multiscale Modelling of Atomistic Structure of Calcium Silicate Hydrate
Authors: Abrikosov Alexei I. , Veryazov Valera
Published: October 2022

The atomistic structure of calcium-silicate-hydrate (C-S-H) has been studied by applying force field simulations and quantum mechanical methods. Large number of crystallographically equivalent structures were used to account for the disordered nature of C-S-H. An extensive set of periodic structures of C-S-H (with a variation of chemical composition) has been generated and optimised. Special attention has been paid to two crystallographic models for tobermorite, which are used for the construction of C-S-H models. Re-optimisation of atomic structures, initially optimised with ReaxFF force field, by quantum chemical methods (semiempirical and Density functional theory) have been performed. Although the main structural characteristics of C-S-H remain the same in all calculations, the balance between the amount of OH groups and water in the structure is different. The obtained structures (optimised with a different level of theory) are combined into an on-line database and can be used for a future simulation of C-S-H materials.

The signs/symptoms of serious illness can be subtle in the first few weeks of life, so close monitoring is essential. The World Health Organization has identified nine “danger signs” that are closely associated with morbidity and mortality if not identified early and treated appropriately. This project was undertaken to assess mothers’ knowledge of these danger signs as well as their health seeking behavior before and after newborn danger sign training. From March to September 2021, this community-based interventional study was conducted among women in two rural communities in Enugu State. An interviewer administered questionnaire was used to assess participants’ knowledge of danger signs and care seeking behaviors before and after training on the danger signs of newborns using videos from the Integrated Management of Childhood Illnesses (IMCI). Three months apart, pre- and post-training data were collected for analysis and comparison using SPSS version 20.0 (Chicago IL). The study enrolled a total of 197 women. Only the number of newborns nursed in the past significantly predicted knowledge of danger signs in the sick newborn (p=0.032) among the socio-demographic indices examined. Prior to training, 47% of respondents could not recall any danger signs offhand, compared to 1.5% after training (p=0.001). Knowledge of up to three danger signs significantly increased after training (p=0.001), as did participants who admitted seeking medical help within 24 hours of noticing any danger signs in their newborn (p=0.043). Our study found that training mothers had a significant impact on their knowledge of danger signs in sick newborns as well as their healthcare seeking behavior. As a result, training and retraining of mothers and/or caregivers may aid in improving newborn care and lowering overall infant mortality.

Psoriasis is a chronic inflammatory disease which mostly affects skin. Tildrakizumab is a specific anti-interleukin-23p19 monoclonal antibody approved for the treatment of plaque psoriasis in adults. Herein, we report about a patient who came to our attention for a moderate-to-severe plaque psoriasis, involving primarily upper limbs, elbow, abdomen and knees (PASI 18 – DLQI 22). His medical history was relevant for epilepsy controlled pharmacologically. In addition, an eczematous and edematous appearance of the tibial area was detected; the histologic findings did not contradict the diagnostic hypothesis of subacute spongiotic dermatitis. The patient was treated with Tildrakizumab. After 12 weeks the clinical lesions improved significantly, and the eczematous component disappeared in the tibial area bilaterally. The clinical improvement was maintained even after one year of therapy. Tildrakizumab showed excellent results in the control of psoriasis, with an excellent safety profile. The promising results of clinical trials have been confirmed in a real-life setting. There are no reports about its safety in epileptic patients. In our case, neurological adverse events did not verify and tildrakizumab managed to control both the psoriatic and eczematous components

Advancing technology has made capital investment an important problem in many companies. Since investment decisions may have serious effects on the company’s liquidity, operational flexibility and profits, they require careful analysis. Investment proposals having different time patterns of savings or earnings are not comparable unless outlays or receipts associated with the alternative proposals are converted to their equivalent amounts at a common point in time. This conversion is accomplished by discounting future cash flows to a chosen date, using an appropriate rate of interest.This article illustrates the utility of the present worth technique in evaluating alternate proposals.

Fifth Era (5G) Innovation is a new age of versatile organizations. In this paper, assessments in versatile correspondence innovation are introduced. In every development, numerous difficulties were confronted that were caught with the assistance of cutting edge portable organizations. Among every one of the beforehand existing versatile organizations, 5G gives a high velocity web office, whenever, anyplace, for everybody. 5G is marginally unique because of highlights, for example, interconnecting individuals, and controlling gadgets, items, and machines. 5G versatile framework will bring different degrees of execution and capacity, which will act as new client encounters and interface new ventures. The mm-Wave beamforming configuration lessens the expense and power utilization which is lined up with an energy-productive plan vision of 5G. In this paper, we track the advancement in crossover beamforming for enormous MIMO correspondences with regards to framework models of the half breed handsets' designs, the computerized and simple beamforming lattices with the conceivable radio wire arrangement situations and the mixture beamforming in heterogeneous network (HetNET). This article gives a brief description about key enablers to enhance the beamforming in 5G network.

The main objective of this research is to evaluate the influence of intelectual human capital transformation, from the student´s perception, through the Open University of Brazil’s  distance education in the municipality of  Camaçari, which is an industrial hub in the metropolitan area of Salvador, Bahia. At this rate, education and development are closely connected, pondering previous studies where this approach is present. Meanwhile, distance education (DE) streamlines through its capillarity in several regions altering the perception and the way of transmitting knowledge. Additionaly, it enables significant changes if we relate the human capital and the field of study, considering cultural, ethical and social aspects. From a methodological point of view, descriptive research has been chosen, using qualitative inquiry. In relation to the methodological process, the Survey method research has been used. This study is justified due to the dimension in which the distance education has been widespread in Brazil and worldwide. As it is a regulated model by the superior instances of education in Brazil, and thus a more detailed one, it deserves more emphasis, once it often approaches DE, human capital and the region where it lies in. Following this understanding, studying the activities of the Open University of Brazil (OUB) in Camaçari, contributes to the perception of changes in the logic of education offer in the distance model, deployment in culture in a general scope and the perception of social freedoms in the object region of study. Hence, it is evident that the DE conducted by OUB in Camaçari gives rise to conditions for training and improving human capital taking into account its urban and social infrastructure, among other factors that combined, foster fertile ground to mitigate the social asymmetries while expanding individual freedoms and the progress of the region.
TODA-YAMAMOTO CAUSALITY TEST BETWEEN ENERGY CONSUMPTION AND ECONOMIC GROWTH: EVIDENCE FROM A PANEL OF MIDDLE EASTERN COUNTRIES.
Authors: AİMER Nagmi , DİLEK Serkan
Published: October 2022

In this paper, we examine the intertemporal causal relationship between economic growth and energy consumption in the selected sixteen the Middle East and North Africa countries by annual data (1985–2016). Unlike the majority of the previous studies and as an alternative to the conventional method of having the same integration of time series and large samples, the Autoregressive Distributed Lag (ARDL) bounds test approach and causality analysis were applied by Toda & Yamamoto (1995). The results of the bounds test show that there is a stable long run relationship between economic growth and total final energy consumption. On the other hand, the results of the causality test, show that there is a unidirectional causal flow from economic growth to total energy consumption that energy conservation policies may not unfavourable effects on economic growth. Overall, these countries meet the conservation hypothesis which means that the causal aspect is unidirectional from economic growth to total final energy consumption and that energy conservation policies will have little or no negative impact on growth in these energy-dependent countries.

This paper investigates the beliefs of the English for Specific Purposes Teachers (ESPTs) about their roles in teaching English Technical Vocabulary (ETV) in a Saudi Arabian Industrial college called Yanbu Industrial College (YIC). It also aims to find the reasons behind their beliefs and explores the extent to which their beliefs go in line with the literature available about this topic. Methodologically, a qualitative study under the case study tradition was conducted. Six ESPTs were interviewed to understand their beliefs regarding their roles in teaching technical vocabulary and the reasons behind their stated beliefs. The study found different beliefs held by ESPTs. They believed that ETV items form should be taught by them, meaning should be introduced jointly with subject teacher and use should be taught by subject teachers due to its advanced technicality. The study suggested some educational implications and recommended experts in the area to carry out future scrutiny to understand this topic from different dimensions.
