L'énergie éolienne en Europe
Authors: Fodor Ferenc
Published: May 2021

Ce chapitre présente une analyse sémio-discursive de la médiatisation de l’éolien terrestre et maritime. Un autre aspect de la notion d’acceptabilité sociale est ici mis au jour : celui se fondant sur les ambivalences qui structurent les énoncés discursifs portant sur cette source d’énergie. L’approche sémiologique permet de révéler les différentes isotopies et montre les sens implicites qui s’expriment à travers des choix lexicaux ou visuels, révélateurs de peurs, d’angoisses ou d’une vision positive d’un modèle de développement en émergence encore imparfaitement défini. Angoisse et enthousiasme nourrissent ainsi les imaginaires socio-discursifs des conflits qui se nouent autour des dimensions financières et environnementales de ces projets comme autant de topiques qui structurent les différents récits.
L'énergie éolienne en Europe
Authors: Bafoil François
Published: May 2021

À partir des données recueillies dans les études empiriques (chap. 1 à 5), ce chapitre de synthèse établit une classification de différents types d’acceptabilité sociale (positive, moyenne, nulle) en insistant sur la réaffirmation du rôle de l’État, la variété des innovations (institutionnelles, financières et politiques), l’accroissement de la demande de participation locale pour toute décision d’investissement dans l’éolien et, enfin, l’irréductibilité de chaque situation donnant ainsi à penser la limite de toute européanisation.
Tramway et art public
Authors: de Fleurian François , de Fleurian Luce
Published: May 2021

Cet article explore les conditions d’élaboration et de mise en œuvre d’une commande publique d’œuvres d’art autour du tramway dans une sélection de six villes. C’est à Strasbourg que les premières réalisations sont intervenues à l’inauguration de la première ligne en 1994. Par la suite, d’autres réseaux ont emboîté le pas à la capitale alsacienne, en attirant de grands noms de l’art et du design comme Daniel Buren (Mulhouse puis Tours) ou Ben (Nice), et l’art public ne s’est pas limité à des œuvres positionnées au fil des lignes. Les équipements fixes ou le matériel roulant sont devenus eux-mêmes des supports comme à Montpellier ou à Tours.
L’Architecture localement bio- et géo-sourcée de Christophe Aubertin : régionaliste, biorégionaliste ?
Authors: Rollot Mathias
Published: May 2021

Dans un contexte contemporain de critique généralisée des idéologies extractivistes, productivistes et naturalistes occidentales, l’article interroge un corpus d’œuvres bâties de l’architecte lorrain Christophe Aubertin dans une optique de réhabilitation de l’idée de ressources pour l’architecture. Au travers d’un questionnement sur les caractéristiques « régionalistes » ou « biorégionaliste » de cette pratique architecturale, l’argumentation cherche à mettre en lumière les aspects à la fois éthiques, esthétiques mais aussi politiques de cette utilisation disciplinaire des ressources locales tant bio- que géo-sourcées.
Aux origines de la francophonie
Authors: Suso López Javier , Fernández Fraile Maria Eugenia
Published: May 2021

Notre réflexion s’organise en deux volets qui se succèdent d’un point de vue chronologique : le premier veut montrer la genèse de l’expression « langue de civilisation », qui fait fortune dans les années 1920, 30, 40 et 50, et les notions (multiples et complexes) auxquelles elle est rattachée, à travers les positionnements d’une série de linguistes du début du XXe siècle ; une fois construite cette notion, et acceptée par la communauté des « intellectuels » de l’époque, elle est reprise pour appuyer une action politico-linguistique concrète, axée sur l’idée du français comme langue de civilisation (Unesco, Français élémentaire). Le tournant pris par la décolonisation écartera rapidement cette expression au profit de deux autres : le français « langue de culture » et « langue et civilisation françaises ».
L’aventure ambiguë d’un pays bilingue. Le cas du Cameroun
Authors: Bikoï Félix Nicodème
Published: May 2021

Pour contrer la nostalgie de l’époque allemande, les autorités françaises à l’époque coloniale créent la JEUCAFRA destinée à promouvoir l’amitié franco-camerounaise. Mais cette organisation, en même temps qu’elle défend la présence de la France au Cameroun, réclame plus de liberté pour les Camerounais. L’indépendance acquise en 1960 permet la réunification du Cameroun francophone et du Cameroun anglophone. Dès lors va commencer pour les dirigeants du pays un subtil jeu d’équilibre qui consiste à affirmer son appartenance à la francophonie, sans y adhérer entièrement.
Comenius (1592-1670) et le plurilinguisme
Authors: Caravolas Jean Antoine
Published: May 2021

Combien de langues un homme devrait-il connaître : une ? deux ? plusieurs ? toutes ? comment les apprendre et comment les enseigner ? Vieilles questions, toujours sans réponse.À ma connaissance le premier à s’occuper de multilinguisme de manière approfondie, à proposer des solutions pertinentes et à esquisser une base théorique pour la didactique du multilinguisme est Jan Amos Comenius. Il le fait dans Didactica Magna (1657), dans Methodus linguarum Novissima (1649) et dans Panglottia, cinquième livre de son magnum opus De Rerum Humanarum Emedatione Consultatio Catholica (1966).Dans mon exposé, j’examine l’opinion de Comenius sur les avantages et les inconvénients de l’unilinguisme (monoglottia), du bilinguisme (diglottia), du multilinguisme (polyglottia) et de la panglottie. Je me penche également sur son projet d’une éducation universelle pansophique et multilingue et sur les principes théoriques de base de sa didactique du plurilinguisme.A la fin, j’explique les raisons pour lesquelles ses suggestions furent après sa mort oubliées, comment elles sont présentement redécouvertes par les spécialistes de la pédagogie des langues et pourquoi elles sont aujourd’hui adoptées et promues par l’UNESCO et l’Union Européenne.
Le débat des langues dans l’enseignement secondaire en Suisse romande au XIXe siècle
Authors: Extermann Blaise
Published: May 2021

L’article traite de trois arguments majeurs ayant traversé les débats relatifs à l’introduction des langues vivantes : le caractère formatif de l’enseignement classique, l’utilité pratique des langues vivantes, leur vocation nationale. En adoptant un point de vue local, centré sur l’enseignement public dans quatre cantons romands (Genève, Vaud, Neuchâtel et Fribourg), en privilégiant les sources produites par les enseignants eux-mêmes, et en analysant l’évolution reliant deux périodes clés de l’histoire de l’institution scolaire, il met en évidence quelques variations que subit cet argumentaire. Il examine du même coup l’évolution des structures scolaires qui accueillent l’enseignement des langues vivantes.
Breeze or storm? The European Reform Movement and Dutch Foreign Language Teaching, c1880-1920
Authors: Wilhelm Frans
Published: May 2021

The drift of nearly all publications on the history of Dutch FLT is that the impact of the European Reform Movement (c1880-1910) was insignificant. However, the question is on what information this notion is based. From the comments of a number of persons who published their ideas during the 1930s - some 25 years after the Reform debate had fallen silent - it appears that their knowledge of the historical facts was small. And it seems that the comments of later critics are not based on proper research either. The question is if there was anything like a Dutch Reform Movement and, if so, in how far it was influenced by other European countries. Whoever wants to study the impact of the European Reform Movement on Dutch FLT should make systematic use of certain historical sources. This paper proposes four types of sources with which to address the research question. The paper first gives a brief sketch of the principles of the international Reform Movement. Next, it presents a picture of Dutch FLT around 1880. Finally, it describes the Dutch Reform in detail with the help of the aforementioned four types of sources. In the concluding paragraph I present my characteristic of the Movement in the Netherlands.
Antecedentes da Lealdade de Doadores de Instituições Filantrópicas: O Papel do Apego e da Confiança
Authors: Machado Andrelino Olímpio Vieira , Gonçalves Filho Cid , Tolentino Renata Sousa da Silva
Published: May 2021

O marketing focado no relacionamento consumidor-marca representa uma ferramenta estratégica e eficiente na criação e permanência de um relacionamento positivo entre as empresas e seus clientes,  e é bastante utilizado por organizações que visam o lucro. As instituições sem fins lucrativos diante das dificuldades de financiamento de suas atividades, podem utilizar o CBR (Consumer-Brand Relationships) para estreitar e aprofundar os laços com os atuais doadores, colaborando assim para a construção da lealdade e permanência dessas doações. Este trabalho teve o objetivo de estudar e compreender o papel do apego e da confiança na geração de lealdade de doadores em instituições filantrópicas. Para tanto foi realizada pesquisa quantitativa com a coleta de 339 questionários entre doadores reais. O modelo hipotético foi analisado por meio da modelagem de equações estruturais com o AMOS 23. Os resultados obtidos confirmaram que o apego juntamente com a confiança são bases para a geração de lealdade de doares, explicando 82% da lealdade. Neste sentido, este é o primeiro trabalho que trata do apego e da confiança como antecedentes simultâneos da lealdade de doações em instituições filantrópicas.
Efficacy of Phytoseiulus persimilis and Amblyseius swirskii for integrated pest management for greenhouse cucumbers under Mediterranean environmental conditions
Authors: Abou-Haidar André , Tawidian Patil , Sobh Hana , Skinner Margaret , Parker Bruce , Abou-Jawdah Yusuf
Published: May 2021

The greenhouse cucumber pests, Bemisia tabaci (Hemiptera: Aleyrodidae), Frankliniella occidentalis (Thysanoptera: Thripidae), and Tetranychus urticae (Acari: Tetranychidae), are major threats to the production of greenhouse cucumbers (Cucurbitaceae) in Lebanon. The development of insecticide resistance by these pests has prompted the use of alternative and sustainable pest management strategies. In this study, we used integrated pest management strategies, including the release of the biological control agents, Amblyseius swirskii Athias-Henriot (Mesostigmata: Phytoseiidae) and Phytoseiulus persimilis Athias-Henriot (Mesostigmata: Phytoseiidae), to control whitefly, thrips, and two-spotted spider mite populations on greenhouse cucumber plants in two commercial production sites (sites A and B). We also compared the efficacy of pest population suppression using the integrated pest management strategy with that of chemical pest control. Our results show that biological control effectively maintains the cucumber pest populations below the economic threshold when coupled with additional integrated pest management measures. In addition, we show that biological control agents were equally or more effective in pest population suppression compared to eight and 12 insecticidal and acaricidal sprays performed in the control greenhouses at sites A and B, respectively. Altogether, our results show the efficacy of adopting integrated pest management and biological control for pest population suppression in greenhouse cucumber production under Mediterranean environmental conditions.
Assessment of genetic diversity and population structure of Eulaema nigrita (Hymenoptera: Apidae: Euglossini) as a factor of habitat type in Brazilian Atlantic forest fragments
Authors: Costa Claudinéia Pereira , Machado Clycie Aparecida da Silva , Francoy Tiago Mauricio
Published: May 2021

In many organisms, habitat affects ecological and genetic diversity and, for certain species, it is expected that a large population should have higher genetic diversity than a smaller population. We analysed the genetics of males of the orchid bee, Eulaema nigrita (Hymenoptera: Apidae) and examined the links between local abundance and habitat with genetic diversity. We also investigated the impact of landscape features on genetic population structure, through microsatellite and mitochondrial DNA analysis, among populations found across 700 km of Brazilian Atlantic forest fragments. We found that genetic variation was not a function of local abundance, but it correlated significantly with habitat. There was significant but low genetic differentiation among populations. We found a single mitochondrial DNA haplotype in all sequenced specimens, which may be widespread throughout the Atlantic forest. Our results reinforce the idea that orchid bees can fly long distances. High-dispersal capacity, together with insufficient time in eventual isolation, can directly contribute to the high degree of similarity among populations for this species, despite their wide geographical distribution.
Design of TCR Structural Variants That Retain or Invert the Normal Activation Signal
Authors: Mock Jee-Young , Oh Julyun , Yi Jason , Daris Mark E , Hamburger Agnes , Kamb Alexander
Published: May 2021

We designed variant human TCRs composed of the full-length TCRα/β or extracellular and transmembrane domains of the associated CD3 subunits fused to polypeptides derived from proteins thought to either enhance or inhibit normal T cell function. First, we showed that the C termini of both the TCR α- and β-chains can accommodate specific additional sequences, without abrogating complex formation or acute sensitivity of the receptor. Replacement of ITAMs with ITIM-containing intracellular domains inverted the TCR signal (i.e., created a ligand-dependent inhibitory receptor). The normal signaling function of the CD3 complex was transferable to the TCR by eliminating all CD3 ITAMs and grafting three to six ITAMs onto the C termini of the α/β-chains, with no effect on acute sensitivity. The observation that TCR variants of such diverse C-terminal composition can fold and function as signaling receptors demonstrates substantial structural and functional malleability of TCRs. These results add to knowledge about TCR structure–function with regard to acute signaling and may provide a route to use TCRs in different ways for T cell therapy.
Old and new nomenclatural combinations for Echinochloa esculenta (Japanese millet) and E. frumentacea (Indian millet) (Poaceae)
Authors: Banfi Enrico , Galasso Gabriele
Published: May 2021

Echinochloa esculenta and E. frumentacea are crops derived from the wild E. crus-galli and E. colona respectively. They are currently treated at the species rank, although different infraspecific ranks have been proposed for both taxa in the past. After some considerations on domestication of Japanese and Indian millets, we propose to follow the concept by Harlan and De Wet, which implies the subspecific rank for the domesticated plants. Accordingly, the existing combination for Echinochloa esculenta is recovered and a new combination for E. frumentacea is here established.
Screening Electrocardiogram in Young Athletes and Military Members: A Systematic Review and Meta-Analysis
Authors: Lear Aaron , Patel Niraj , Mullen Chanda , Simonson Marian , Leone Vince , Koshiaris Constantinos , Nunan David
Published: May 2021

Objective

To determine the effect of electrocardiogram (ECG) screening on the prevention of sudden cardiac arrest and death in young athletes and military members.

Data Sources

MEDLINE, Embase, CENTRAL, Web of Science, BIOSIS, Scopus, SPORTDiscus, PEDro, and ClinicalTrials.gov were searched from inception to dates between February 21 and July 29, 2019.

Study Selection

Randomized and nonrandomized controlled trials in which preparticipation examination including ECG was the primary intervention used to screen athletes or military members aged ≤40 years. Acceptable control groups were those receiving no screening, usual care, or preparticipation examination without ECG. Three published studies and 1 conference abstract were identified for inclusion.

Data Extraction

In all 4 studies, risk of bias was assessed using the Cochrane risk-of-bias tool and was found to be generally high. Two studies had data extracted for random effects meta-analysis, and the remaining study and conference abstract were included in the narrative review. The overall quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach.

Data Synthesis

We included 4 nonrandomized studies (11 689 172 participants), of which all had a high risk of bias. Pooled data from 2 studies (n = 3 869 274; very low-quality evidence) showed an inconclusive 42% relative decrease in risk of sudden cardiac death (relative risk = 0.58; 95% CI = 0.23, 1.45), equating to an absolute risk reduction of 0.0016%. The findings were consistent with a potential 77% relative decreased risk to a 45% relative increased risk in participants screened using ECG. Heterogeneity was found to be high, as measured using I2 statistic (71%). Data from the remaining study and abstract were similarly inconclusive.

Conclusions

Existing evidence for the effect of ECG screening is inconclusive and of very low quality. In our meta-analysis, we observed that screening ECG may result in a considerable benefit or harm to participants. Higher-quality studies are needed to reduce this uncertainty.
Incidence of Sudden Cardiac Arrest and Death in Young Athletes and Military Members: A Systematic Review and Meta-Analysis
Authors: Lear Aaron , Patel Niraj , Mullen Chanda , Simonson Marian , Leone Vince , Koshiaris Constantinos , Nunan David
Published: May 2021

Objective

To evaluate the quality of the evidence on the incidence of sudden cardiac arrest (SCA) and sudden cardiac death (SCD) in athletes and military members and estimate the annual incidence of SCA and SCD.

Data Sources

We searched MEDLINE, Embase, Cochrane CENTRAL, Web of Science, BIOSIS, Scopus, SPORTDiscus, PEDro, and ClinicalTrials.gov from inception to dates between February 21 and July 29, 2019.

Study Selection

Studies in which the incidence of SCA, SCD, or both in athletes or military members aged <40 years was reported were eligible for inclusion. We identified 40 studies for inclusion.

Data Extraction

Risk of bias (ROB) was assessed using a validated, customized tool for prevalence studies. Twelve had a low ROB, while the remaining 28 had a moderate or high ROB. Data were extracted for narrative review and meta-analysis.

Data Synthesis

Random-effects meta-analysis was performed in studies judged to have a low ROB in 2 categories: (1) 5 studies of regional- or national-level data, including athletes at all levels and both sexes, demonstrated 130 SCD events with a total of 11 272 560 athlete-years, showing a cumulative incidence rate of 0.98 (95% CI = 0.62, 1.53) per 100 000 athlete-years and high heterogeneity (I2 = 78%) and (2) 3 studies of competitive athletes aged 14 to 25 years were combined for a total of 183 events and 17 798 758 athlete-years, showing an incidence rate of 1.91 (95% CI = 0.71, 5.14) per 100 000 athlete-years and high heterogeneity (I2 = 97%). The remaining low-ROB studies involved military members and were not synthesized.

Conclusions

The worldwide incidence of SCD is rare. Low-ROB studies indicated the incidence was <2 per 100 000 athlete-years. Overall, the quality of the available evidence was low, but high-quality individual studies inform the question of incidence levels.

Histopathological Study of Verrucous Lesions and its Mimics
Authors: Chauhan Kriti , Jassal Vikram , Sara Gazalpreet Kaur , Bansal Vijay , Hatwal Varun
Published: May 2021

Context:

Verrucous lesions pose a diagnostic challenge to the clinicians as well as pathologists. There are few discrete histological features which if looked for carefully can help differentiate them.

Aim:

The aim of this study is to bring into light the histological features of several verrucous lesions occuring on skin and mucosa lined by squamous epithelium.

Settings and Design:

This is a 6-month prospective and retrospective study done on cutaneous and squamous mucosal biopsies with an exophytic pattern of growth. Clinical details along with the diagnosis were retrieved from the case files and correlated with the histological diagnosis.

Subjects and Methods:

Only hematoxylin and eosin-stained sections were studied.

Results:

Of the 35 cases, 10 (28.5%) were female and 25 (71.4%) were male. The size of the lesions ranged from 0.5 cm to 6.5 cm. The site of lesions included anogenital (8 cases, 22.8%), cutaneous (24 cases, 68.5%), and oral mucosal (3 cases, 8.5%) areas. Warts were found to be the most common lesions (14 cases, 40%), of which cutaneous warts comprised 9 cases (64%) and genital warts comprised 5 cases (36%). It was observed that benign warts were clinically confused with other rare cutaneous lesions such as polyps and cysts. Malignant counterpart of a wart or condyloma called as warty carcinoma was not known to many and was mistaken for a conventional squamous cell carcinoma.

Conclusion:

Histology is of utmost importance in differentiating the several verrucous lesions because sometimes clinical appearance may mimic one another.
Health care workers experiences in emergency obstetric care following implementation of an in-service training program: case of 2 Referral Hospitals in Botswana
Authors: Nkhwalume Ludo , Mashalla Yohana
Published: May 2021

Background: Maternal mortality rate remains a challenge in many developing countries.

Objectives: This study explored experiences of Health Care Workers on Emergency Obstetrics Care (EMOC) in-service training and its effect on maternal mortality.

Methods: Descriptive qualitative study design was conducted using in-depth interviews and focus group discussions. Par- ticipants were EMOC trained midwives and doctors purposively selected from the 2 referral hospitals in the country. Data were transcribed verbatim, coded, and analysed using Grounded Theory approach.

Results: Four themes emerged including training, EMOC implementation, maternal death factors and EMOC prioritisation. The duration of training was viewed inadequate but responsiveness to and confidence in managing obstetric emergencies improved post EMOC training. Staff shortage, HCWs non-adherence and negative attitude to EMOC guidelines; delays in instituting interventions, inadequate community involvement, minimal or no health talk to women and their partners and communities on sexual reproductive matters and non-prioritisation of EMOC by authorities were concerns raised.

Conclusion: Strengthening health education at health facility levels, stakeholders’ involvement; and prioritising EMOC in-service training are necessary in reducing the national maternal mortality.

Keywords: Maternal mortality; health care workers; EMOC, in-service training.
Emerging Technology Mediation among Pre-service History Teachers at Makerere University
Authors: Sebbowa Dorothy Kyagaba , Nabushawo Harriet Mutambo
Published: May 2021

General pedagogy in higher education is constrained in terms of creativity and innovation. In the area of History Education, many teachers view history as a single accurate story about the past so they are slow in embracing dialogic and inclusive pedagogies that are mediated by emerging technologies (ETs) that can bring interpretation of the past in conversation with the present. This may become an impediment to improving the quality of learning since today’s students need to be taught using ETs that are aligned with the way they learn and think. Therefore, this study sought to support students’ participation in doing history mediated by ETs. Data was collected using interviews and observation from an educator and 20 pre-service teachers at Makerere University. The data were analysed through a Hermeneutic cycle-driven analysis. The findings revealed that historicity is constructed through active engagement in doing history by interpreting images, videos, pictures and texts as relics from the past afforded by ETs. Dialogical approaches to learning history through open conversations between the educator and students embedded by ETs helped the pre-service teachers to learn in a democratic way. If utilized this will be relevant to the pre-service teachers’ future students.
Adaptation of the ADKAR Model to the Management of the Higher Education Student Loan Scheme in Uganda
Authors: Mukwenda Hilary Tusiime
Published: May 2021

The financing of higher education through student loan schemes is a recent phenomenon in Uganda. It constitutes a major change in the financing of higher education in the country and, naturally, it has not been without controversy. Its processes have posed challenges to both its beneficiaries and implementers. For instance, the loan policy’s sustainability is yet to be guaranteed. It is with this understanding that this paper discusses how application of the ADKAR change management model can promote the performance and sustainability of the policy. Designed to help individuals and organisations, the model prescribes a five-step process towards adopting change and leveraging its power to bring about improvement by enhancing ability to confront new situations. In this paper, this process is proposed for ensuring effective disbursement of student loans, determination of interest rates and recovery of the loans from borrowers.
Challenges of Technical and Vocational Education and Training in Nigerian History
Authors: Oladejo Mutiat Titilope
Published: May 2021

Technical and Vocational Education (TVE) is a chequered aspect of education in contemporary Africa.  This paper examines the complicated realities of TVE in Nigeria. In practice, indigenous education systems embedded a standard learning procedure which British colonial administration keyed into and standardised in non-formal arrangements through government departments. Therefore, the paper tracks the (dis)oriented education-industry relationship that existed after 1960. TVE in Nigerian societies has rarely improved to revolve modern technology attuned to global development and still grapple with inadequate technical applications which implies an educational gap. It unravels the governmental and non-governmental interventions. Recently, entrepreneurs and industrialists in Nigeria identified technical education as a panacea by planning to fill the learning gap through the establishment of technical universities that reflect modernisation. Accumulation and circulation of skills in TVE learning feature a process of continuity and change which explains how old and new learning systems reflect. The methodology adopted is historical and it is intertwined with the context of education systems, politics and economy.
Status and Performance of University Librarians in Uganda
Authors: Namuleme RK
Published: May 2021

The thesis of this study is that the status of the university librarian is of significant value to his/ her performance. This study set out to ascertain this significance by investigating the status and performance of librarians in selected universities in Uganda. The findings were that the status of the university librarians in the country is only fairly satisfactory. It was also found that the status of university librarians is a significant predictor of their performance. Therefore, the paper urges university administrators in the country to re-examine the status accorded to their librarians because it is an important ingredient in their performance.Keywords: Library management; Performance management; Human resources development.
Staff Turnover in Public Universities in Uganda
Authors: Kyaligonza Robert , Kamagara Edson
Published: May 2021

In this study, we examined three sets of antecedents of staff turnover in public universities in Uganda: demographic, controllable and uncontrollable. Data were collected from lecturers and administrators at the universities. Our findings suggest that the extent of controllable turnover is greater than uncontrollable turnover and that poor management practices are the major cause of employee turnover. Poor motivation was reported to be a major problem. In particular, economic incentives were found to be grossly inadequate to retain lecturers in the university system. Therefore, it is recommended that the universities upgrade their incentive systems, especially the economic motivators. The study also revealed that there is a pressing need to make the lecturers working environment conducive for the universities core functions of teaching, research and community engagement.
Precambrian tectonic inheritance control of the NE Brazilian continental margin revealed by Curie point depth estimation
Authors: Cruz Oliveira Jefferson Tavares , Barbosa José Antonio , de Castro David , Correia Paulo , Magalhães José Ricardo , Correia Filho Osvaldo , Buarque Bruno
Published: May 2021

An investigation of Curie point depths (CPD) based on spectral analysis of airborne magnetic data was carried out in the NE Brazilian continental margin. The studied region represents a narrow hyper-extended margin with three sedimentary basins. Regional geothermal gradient and heat flow were also calculated. CPD results were integrated with interpretation of 2D deep seismic data and with estimated isostatic Moho depths. The results reveal that the narrow hyper-extended crust is 150 km wide in the southern sector and 80 km wide in the north, with a narrow ocean-continental transition (OCT) zone that varies from 50 km wide in the south sector to 30 to 20 km wide in the north. The CPD isotherm showed the strong influence of the three main continental blocks of Borborema ́s Shield in the tectonic evolution of the three marginal basins. The CPD analysis corroborated models provided by gravimetric data and successfully demonstrated the sharp control of basement compartments on the thermal properties of the marginal basins domains
Rock magnetic and micro-morphological analysis on snow deposits: recognition of anthropogenic origin of particulate matter in urban and wilderness areas (central Italy)
Authors: Alfonsi Laura , Macrì Patrizia , Nazzari Manuela
Published: May 2021

Low field magnetic susceptibility and other rock magnetic analyses are applied to inspect the magnetic nature of solid residuals in snow samples collected in downtown Rome and in two Natural Parks in central Italy. Field emission scanning electron microscope and energy dispersive spectroscopy (FESEM-EDS) analyses are utilized to reveal the nature of Fe-rich particles and discriminate their anthropogenic origin. The results indicate that magnetite (Fe3O4) is the main magnetic carrier in almost all samples and that the variations in concentration are directly associated with local sources of particulate matter (PM) from anthropogenic pollution related to automotive circulation in both environments. Magnetic minerals of other provenance are found as accessories. The snow deposits revealed to be an efficient neutral tool for fine particle collections, also in environments characterized by different concentration and source of pollutants.

Published: May 2021

Abstract

The formation of the Draft Law through the Omnibus Law method raises resistance in the community and a number of its contents have caused controversy. The research objective is to find out the concept of the Omnibus Law of the Job Creation Law in a sociological (legal sociology) perspective by focusing on the resistance of the community to the ratification of the Job Creation Law and the role of the company in responding to the process of resistance by the community. The research method uses descriptive qualitative methods, by searching for data sources obtained from various literature studies such as journals, articles, news, mass media and so on. The results show that there are several causes of community resistance to the ratification of the Job Creation Law and the more dominant role of companies in supporting the ratification of the Job Creation Law. The conclusion is that since the draft law becomes the work copyright law, it is still reaping resistance among the public.

This essay aims to establish how much influence the economic policies do have on staff motivation practices used by business organizations, in the context of their strategic analysis. To achieve this, there will be a tour of theoretical reflections related to the characteristics of the political system and the understanding of economic policies as a product of their interactions.
In a didactic way, specific economic policies are visited considering their objectives and implementation instruments. The link between economic policy and environmental analysis is established; also, the relationship between the inner environmental analysis and human resources management. Finally, a set of company practices to motivate their staff are listed.
All this sequence of concepts, from the political system, economic policy, analysis of the environment and surroundings, the role of human resources and motivational activities; creates a sufficient frame of reference to be able to conclude on the impact of economic policy on the motivation of individuals affiliated to a business system.

The swelling behavior of 18Cr10NiTi austenitic stainless steel irradiated with energetic Ar-ions in the dose range of 40…105 displacements per atom (dpa) with simultaneously implanted argon to the levels of 0.08…6.3 at.% at temperatures of 550…700 ºC was investigated. Transmission electron microscopy (TEM) has been used to study the microstructure evolution and to determine the dependence of swelling on the damage and Ar concentration. It is shown that the highest density and average size of the cavities was observed in the region of the calculated peak damage and Ar concentration. Argon was found to promote cavity swelling at lower temperature. At simultaneous creation of defects and argon implantation it was found a shift of swelling curve to higher temperatures compared to metallic-ion irradiation. The cavity swelling behavior of an austenitic 18Cr10NiTi steel irradiated with energetic argon ions are compared with those resulting from helium implantation.

This paper presents the results of studies on the strength and adsorption characteristics of granular activated charcoals of the brand ISQ DON GW4, С40/4 EXTRA KJ, and Norit RKJ4. The ultimate strength of samples was measured in different states: initial (H2O vapor saturation as a result of long-term storage), dehydrated, I2 vapor saturated and H2O + I2 vapor saturated. A significant (25…40%) decrease in the activated charcoal fracture stress due to the iodine vapor saturation, concerned with a Rehbinder effect, was observed. The degree of the adsorption decrease in the sorbent mechanical stability should be taken into account when selecting sorbents for filters of NPP air discharge purification systems (ventilation systems).

MEMLÜKLERDE SULTAN ŞABAN DÖNEMİ BÜYÜK EMİR İSYANLARI
Songül Akyurt
Özet
Dünyanın neresinde olursa olsun devleti yöneten kişinin çocuk yaşta ve tecrübesiz olması başta vezirler, büyük devlet adamları ve emirlerin devlet yönetimine karışarak hükümdarlar üzerinde tahakküm kurmalarına hatta yönetimi bile ele geçirmelerine neden olmuştur. Bu durumun en güzel örneklerinden biri de 1250-1517 yılları arasında Mısır, Suriye, Hicaz ve Güneydoğu Anadolu’da hüküm süren Memlûk Devleti’nde görülmektedir. Memlûk Devleti’nin XXII. sultanı olan el-Melik el-Eşref Şaban (1363-1377), selefi el-Melik el-Mansûr Selâhaddîn Muhammed’in aklî dengesinin yerinde olmadığı gerekçesiyle emirler tarafından tahtan indirilmesinden sonra 30 Mayıs 1363 tarihinde henüz on yaşında iken tahta oturtulmuş bir sultandır. Onun emirler tarafından sultan yapılması, saltanatının da nasıl geçeceğine dair önemli ipuçları vermiştir. Bu çalışmada, kendisinden önce olduğu gibi Sultan Şaban zamanında da tahtı vesayet altında tutan büyük emirler ve onların adeta döneme damgasını vuran isyanları hakkında ayrıntılı bilgi verilecektir.
Anahtar Kelimeler: Mısır, Memlûk Devleti, Sultan Şaban, Emir, İsyan.
THE GREAT AMİR REBELLİONS IN THE PERİOD OF SULTAN SHABAN
Abstract
Regardless of where you were in the world, the fact that the person who ruled the state was child and inexperienced caused the viziers, great statesmen and amirs to intervene in the state administration and establish dominance over the rulers and even take over the administration. One of the best examples of this situation is seen in the Mamluk State, which ruled in Egypt, Syria, Hejaz and Southeastern Anatolia between 1250-1517. Al-Malik al-Ashraf Shaban (1363-1377), the XXII. sultan of the Mamlûk State, was enthroned on May 30, 1363, when he was ten years old, after his predecessor al-Malik al-Mansur Salâdîn was dethroned by the amirs on the grounds that he was mentally unstable. The fact that he was made a sultan by the amirs gave important clues about how his reign would pass. In this study, detailed information will be given about the great amirs who kept the Sultan Shaban under the their tutelage during the his reign and marked the period with their rebellions.
Key Words: Egypt, Mamluk State, Sultan Shaban, Amir, Rebellion.

A Promising Opportunity for the Integration of Syrian Refugees in Turkey: New Targets in Accessing the Labor Market through Vocational Education and Training
Authors: ÖZER Mahmut
Published: May 2021

In recent years, the wars across the world have dramatically increased the demographic mobility among countries. Particularly, the Syrian civil war led to the displacement of millions of people within Syria and also caused the leave of Syrians from their country. The responsibilities of neighboring countries have increased considerably. Turkey, which has been implementing 'open-door diplomacy' since 2011, is the country hosting the highest number of refugees in the world as of 2021. This study evaluates Syrian refugees' access to vocational education and training (VET) in Turkey. In this context, the importance of policies to increase access to vocational training centers (VTCs), which have a major potential in facilitating their transition to the labor market and supporting their social integration, is highlighted. In addition, new steps taken by the Ministry of National Education (MoNE) towards the integration of Syrian migrants are discussed.
Effective Corporate Social Responsibility (Csr) Delivery as Panacea for Restiveness and Conflict in The Niger Delta: Role of The Mass Media
Authors:   Department of Theatre Arts Faculty of Arts Delta State University Abraka, Nigeria., L. Imiti Aghogho
Published: May 2021

The Niger Delta has been a cauldron of restiveness and violent conflicts. Most of these conflicts result from the failure of the multinational corporations operating in the region to adequately discharge their Corporate Social Responsibility to the people. It is against this backdrop that this paper examines the issue of Corporate Social Responsibility as the panacea for the restiveness and conflict in the region as we as the crucial role the mass media have to play in assisting the corporate organisations to effectively discharge their obligations to the people. It is propounded here that failure to disseminate relevant information in this regard has led to mistrust and misunderstanding which eventually culminate in restiveness and conflict. The role of the media is therefore equally examined. The paper discovers that the media are constrained in the performance of this role. These constraints are presented and ways of tackling them are proffered.

Authors: KAVAK Onur , KAYGIN Erman
Published: May 2021

Havacılık sektörü, küresel anlamda ekonomik, sosyal, siyasal gelişmelerden kaynaklanan etkilere son derece açık olmakla birlikte, kendi bünyesinde yer alan finansal, stratejik ve operasyonel kırılganlıklar dolayısıyla hem içsel hem de dışsal boyutlu risklerden etkilenen, oldukça hassas bir yapıdadır. İçsel risklere yönelik bir takım mekanizmalarla öngörüde bulunup tedbirler alınabilse de, dışsal risklere ilişkin öngörüde bulunup tedbir alabilmek her zaman mümkün olamamaktadır. Bahse konu dışsal risklerin başında ekonomik krizler gelmektedir. Küreselleşme ekonomik krizlerin yayılım gücünü arttırmış, dünyanın herhangi bir yerinde meydana gelen bir ekonomik kriz, tüm dünyayı etkisi altına alır hale gelmiştir. Bu çalışmada amaç, 1994, 2000-2001, 2008 ve 2020 ekonomik krizlerinin havacılık sektörü üzerinde yarattığı etkileri Türkiye perspektifinden ele alıp değerlendirmektir. Bu bağlamda sektörün gelişimi ile krizler arasındaki ilişki, bahse konu krizlerin tüketici tercihlerine etkisi, krizler dolayısıyla sektörel küçülme oranları, toparlanma süreleri gibi hususlar üzerinde durularak, Covid-19 pandemisinin havacılık sektörüne ilişkin etkilerine yönelik öngörüde bulunulmaya çalışılmıştır.
Investigation of Types of Errors Made by Primary School 4th Grade Students Regarding the Concept of Place Value
Authors: KESER Hilal
Published: May 2021

This study aims to examine the types of errors regarding the concept of place value made by primary school fourth grade students. The study was designed as a qualitative one as it defined error types of the students. The study comprised 158 fourth grade students attending four different state schools in the centre of Nevşehir province in 2019-2020 academic year. In order to define the error types of the students regarding place value, “place value concept” test involving 14 questions was used. This test was developed by Sarı and Olkun (2019). Descriptive analysis was used to determine the error types of the students. The themes proposed Paydar and Sarı (2019) were taken into account for “error types”. When the students’ errors were evaluated, it was found that the students were not successful in the areas of doing divisions, writing representations as grouped numbers, doing multiplication with tens and its multiples, showing the value of places in terms of standard units, writing numbers’ way of readings. These findings revealed that the students were not successful with regard to the understanding of conceptual and operational of place value. Enhancing students’ understanding of place value concept is seen significant for other subjects of maths.
