РЕКРЕАЦІЙНА ТРАНСФОРМАЦІЯ ПРИМІСЬКИХ ЛІСІВ ВОЛИНСЬКОЇ ОБЛАСТІ В УМОВАХ СУЧАСНОСТІ
Authors: Ковальчук Н.П. , Герасимчук О.П. , Шимчук Ю.П.
Published: June 2021

У статті проведено аналіз сучасних проблем приміських лісів, зокрема проблеми їх рекреаційної трансформації в умовах Волині. Проаналізовано шляхи забезпечення високої фітомеліоративної ефективності лісу. Описано моделі рекреаційної трансформації лісів в умовах сучасності та визначено модель, яка найбільш оптимальна для лісів Волинської області. Зазначено, що ліси, які трансформувалися за екстенсивною моделлю, опинилися у вирі стихійної рекреації, що негативно позначилося на їх стані (збіднення рослинного і тваринного світу). Встановлена можливість зменшення і врегулювання рекреаційних навантажень на приміські ліси. Дослідження рекреаційної трансформації приміських лісів проводилося з метою раціонального поєднання основного призначення лісопаркової частини з правильною організацією лісокористування. Для дослідження застосовувалися методи спостереження, опису, порівняльного аналізу та синтезу, узагальнення, системний метод, польовий метод та метод маршрутних обстежень. У статті застосовано комплексний підхід до проблеми рекреаційної трансформації приміських лісів із урахуванням дії негативних факторів сучасної урбанізації, що характеризується тенденцією до глобальної зміни клімату. Тому важливим є пошук альтернативних рішень протидії цим процесам у регіонах України, а саме максимальне заліснення та пошук нових видів деревних рослин, що стійкі до сучасних змін клімату і шкідників, а також які б максимально виконували покладені на них фітомеліоративні функції.

Authors: Ольховський В.О. , Дударєв І.М.
Published: June 2021

Очищення зерна від сміттєвих (незернових) і зернових домішок із одночасним сортуванням є обов’язковою технологічною  операцією, яка проводиться після його збирання, а також під час зберігання та перероблення. Для сепарування зернової маси використовують сепаратори різних конструкцій, але найбільш поширеними є сепаратори з плоскими та циліндричними решетами. Сепаратори із плоскими решетами мають перевагу, оскільки під час сепарування уся поверхня таких решіт використовується. Разом із тим, одним із недоліків таких решіт є великі габаритні розміри. Тому пошук конструктивних рішень компактного розташування плоских решіт в сепараторі є актуальним завданням. Серед таких конструкцій із компактним розташуванням решіт можна виокремити сепаратори ножичного типу, в яких решета розташовані на сепарувальних секціях-важелях, що з’єднані навхрест. Для забезпечення постійного розшаровування зернової маси на решетах такого сепаратора, що інтенсифікує сепарування, а також для ефективного очищення отворів решіт від забивання за допомогою гумових кульок, необхідно забезпечити коливання решіт вздовж вертикалі. Моделювання коливального руху конструктивних елементів зернового сепаратора ножичного типу із використанням основних положень теоретичної механіки дозволило встановити закони руху повзунка та рухомої рами сепаратора. Отримані залежності дозволяють розрахувати та обрати раціональні параметри і режими роботи механізму приводу сепаратора ножичного типу.
ЗАСТОСУВАННЯ ЛАЗЕРНОГО ЗМІЦНЕННЯ ДЕТАЛЕЙ АВТОМОБІЛЬНОГО ТРАНСПОРТУ В АПК
Authors: Ковальчук Ю.О. , Лісовий І.О.
Published: June 2021

Проаналізовано вплив лазерного зміцнення на властивості поверхневого шару залізовуглецевих сплавів, з яких виробляються різноманітні деталі автомобільного транспорту. Розглянуто особливості формування мікроструктури в зоні лазерного впливу для залізовуглецевих сплавів у результаті застосування методу поверхневого лазерного оброблення. Визначено, що внаслідок можливості аустеніту спричиняти різний вплив на зносостійкість сплавів, вибір режиму гартування та відповідного йому структурного стану в зоні лазерного впливу повинен проводитися із урахуванням умов експлуатації деталі. Так, для пари тертя циліндр двигуна – компресійне кільце залишковий аустеніт може сприяти кращому припрацюванню цих деталей. Показано розподіл мікротвердості за глибиною гартування зразків із залізовуглецевих сплавів під час оброблення лазером безперервної дії. Представлена залежність глибини зони лазерного впливу в оброблюваному зразку від швидкості лазерного оброблення. Визначено швидкість переміщення лазерного променя поверхнею оброблюваного зразка, за якої з’являється зона плавлення. Показано, що на поверхні зразків, що оброблені СО2-лазером безперервної дії, спостерігається неоднорідний розподіл залишкових макронапружень. Лазерне гартування забезпечує кращі показники відносного зносу, коефіцієнта тертя та числа циклів до припрацювання пар тертя порівняно із звичайним гартуванням. Таким чином, залізовуглецеві сплави можуть ефективно оброблятися лазерним випромінюванням.

CONCEPT OF MANAGEMENT FOR FORMING OF FULL HEALTH OF HUMAN
Authors: Komar  , Dubas  , Al-Tmaizi
Published: June 2021

Concepts of managing the formation of complete human health based on the creation of models of creative management. Research methods. The study used such research methods as system-logical method, attributive and hierarchical methods, analysis, induction and deduction, comparisons and key components. Research results. To date, scientists have failed to formulate a single theoretical and methodological framework for a comprehensive assessment of basic health, so it is necessary to only partially consider its individual types. Depending on the field of knowledge, there are several types of health: physical, mental, mental, spiritual, moral, social, etc., which together form a healthy health.

The authors justify the need to reduce the complexity of the Conceptual Decimal Model by reducing the number of types of good health. To address this issue, it is taken into account that mental and spiritual health belong to the category of "faith", moral and social - have common features and are characterized by a certain specificity, and sexual health is not fully adequate because it is absent in preschool children and most of the elderly. In its updated form, the concept of managing the formation of full-fledged human health is represented by five components: physical, physiological, financial, mental and occupational health.

Studies have shown that the first level of the hierarchical model of managing the formation of complete human health occupies physical health as a state of physical well-being of the human body, which is characterized by its functional readiness to perform the main activities, including professional. Physiological, financial and mental health are located according to the second, third and fourth levels of the five-element hierarchical model of good health and their functions also consist in ensuring the performance of the person in the conditions of his professional activity. Conclusions. The proposed concept of managing the formation of full-fledged human health is a universal, high-performance, five-element hierarchical management model of physical, physiological, financial, mental and occupational health that has a comprehensive impact and provides effective management of the formation of full health and financial health. Human well-being in any social environment that may be the subject of further scientific research.
GLOBAL PRINCIPLES OF MANAGERIAL ACCOUNTING AND THEIR APPLICATIONS AT ENTERPRISES
Authors: LEPETAN Іnna
Published: June 2021

The article describes the list and essence of accounting principles and focuses on the principles of accounting, since not all generally accepted accounting principles are suitable for application in management accounting. The basic principles of management accounting are combined with the integration of different aspects, which are distinguished by different scientists.

The Global Principles of Management, developed by international organizations and identifying best practices in accounting that help to make complex decisions that deliver value, are described in more detail.

The article describes the components of the principles and ways of their application. Attention is paid to the principle “Communication generates influential information”, which means that management accounting begins and ends with communication. The main purpose of this principle is to make effective decisions about the strategy and its implementation at all levels.

The “Information is relevant” principle directs management records to provide managers with relevant information when necessary, identifying past, current, and future information, including financial and non-financial data from internal and external sources. This includes social, environmental and economic data. The purpose of this principle is to provide the enterprise with information support in planning and developing strategy, tactics and their implementation.

The principle of “Impact analysis”, management accounting links the strategy of the organization with its business model. This principle helps to work out different scenarios to understand their impact on value creation and conservation. The main purpose of this principle is to simulate different scenarios that demonstrate cause and effect relationships between activity factors and outcomes.
The purpose of the principle of “Smart management builds trust” is formulated as the need to actively manage relationships and resources to protect the financial and non-financial assets of the company, its reputation and value.
Attention is drawn to the core competencies that management accounting professionals must possess to help an organization create, implement, and refine their strategies. The competency model covers four areas: specialized and business skills, communication skills and leadership.
The application of Global Principles in the fields of activity: cost transformation and management, external reporting, financial strategy, internal control, evaluation of investment efficiency, management and budgetary control, prices, discounts and product decisions, project management, regulatory compliance, management resources, risk management, strategic tax control, financial management, internal audit.
ALTERNATIVE SOURCES OF ENERGY IN GREEN TOURISM
Authors: DZIS Victor
Published: June 2021

The article considers promising areas of green tourism development in Vinnytsia region. Describes a number of extremely unique and interesting objects that are little known to tourists. These include the «Illinets astroblem» ˗ craters at the site of a meteorite fall 400 million years ago. The crater is located between the villages of Ivanky, Lypovets district and Luhovo, Illinets district. They arose as a result of the fall to Earth of a cosmic body with an approximate weight of 40 million tons. The diameter of the meteorite is about 230 - 300 m. At the time of the fall, the meteorite was divided into 3 parts. As a result, 13 craters appeared. The largest of them have diameters of 7-10 km. According to experts, the initial depth of the largest crater was about 800 m. The local places are witnesses of a unique phenomenon of planetary scale and are interesting for the tourist business. There are no analogues to Ilyinets Crater in the world.
The problems of exhaustion of traditional energy sources are analyzed, and in this connection the inevitable increase in their price. The necessity of wide introduction of alternative energy in the field of green rural tourism is proved. The use of autonomous, network and hybrid solar semiconductor power plants is. promising. Grid-connected solar power plants as an object of solar energy can be used both to generate electricity for household consumption and for the purpose of further sale to the national grid at a green tariff.
It is shown that the introduction of solar energy by tourism businesses significantly increases their profits and competitiveness, reduces electricity costs, significantly improves the quality of services, increases the level of tourist service in rural areas. The need for state support and investment for the development of renewable energy sources in rural areas and green rural tourism is substantiated.

Published: June 2021

The article examines the influence of the cluster approach on the formation of the competitiveness of recreational enterprises, as well as the development of their innovative activities. The main purpose of creating a cluster is determined, which is expressed in increasing the competitiveness of the enterprise and the emergence of opportunities for the development of the enterprise. At the same time, one should take into account the peculiarities of tourist clusters, which, despite the existing differences in individual countries and regions, can be formed only as a result of mutually beneficial effective cooperation between private business and the state.
A clausal analysis of free choice demo in Japanese
Authors: Nakanishi Kimiko
Published: June 2021

It is commonly assumed that in Japanese, an indeterminate pronoun followed by demo (indet-demo) corresponds to free choice any in English (FC any). Based on a number of semantic differences between the two, I argue that indet-demo is not a nominal free choice item, but a concealed unconditional adjunct, corroborating the claim made by Nakanishi and Hiraiwa (2019) and Hiraiwa and Nakanishi (2020, to appear). Based on Rawlins’s (2008, 2013) Hamblin analysis of unconditionals in English, I propose a compositional semantics of indet-demo that captures its semantics properties.
Development of an integrated approach to the design of textile rehabilitation products for children
Authors: Korobtseva Nadezhda A. , Golubchikova Anastasia V.
Published: June 2021

This paper reviews the characteristics of emergence formation and development of the Inclusive Design field. As it points out year after year the number of children with health disabilities is increasing, unfortunately. The research has shown that various rehabilitation tools should be developed for disabled children's more successful socialization, development and education. The authors suggests the technical means of rehabilitation classification based on the main material of manufacturing, which includes textile means of rehabilitation. Textile means of rehabilitation are an extensive list of products, comprising inclusive and rehabilitation clothing, technical equipment (for example, fixers for sedentary and bed patients of various purposes) also developing educational aids, as well as textile developing educational toys. Textile materials are differentiated by raw material composition, texture, physical properties, color scheme. This variety allows quick and convenient creation of various rehabilitation means with minimal material costs. Additional multifactorial capabilities are provided by the fact that products can be made from combinations of different textile materials, as well as complement products from other materials. Methods (transformations, combinatorics, etc.) and principles (adaptability, etc.) are defined, which contribute to solving certain problems of designing textile rehabilitation means. The paper comes up with an integrated approach to the design of such rehabilitation devices, which will allow designing products that have the greatest rehabilitation effectiveness. The authors also provide the classification of textile means of rehabilitation on a basis of purpose.
“Mikhailovskoe” Pushkin Readings 2020: “…to the glory of the battlefield Rus’…”
Authors: Nikitin Оleg V. , Uzenev Eduard A.
Published: June 2021

The Mikhailovskoe Pushkin readings, held in the State Museum-Reserve of A. S. Pushkin “Mikhailovskoe” in 2020, were dedicated to the next anniversary of Alexander Pushkin’s arrival in exile to Mikhailovskoe and another significant and very relevant date in the context of modern events — the 200th anniversary of Alexander Pushkin’s visit to the Crimea. At the same time, we are taking into account that 2020 is marked by the 75th anniversary of the victory in the Great Patriotic war, to which the peoples of our multi-ethnic Fatherland made a decisive contribution. The Great Victory is the result of unprecedented feat of our fathers and grandfathers, and this feat is a natural achievement of the centuries — old heroic history of Russia and spiritual development of its peoples. The events of 75 years ago, filled with tragedy and epic grandeur, are experienced with special fullness throughout this year. They defined the cross-cutting content of the conference. The theme of the readings made it possible to recall and comprehend heroic pages of our Fatherland`s history, reflected both in works of folk art and documents, written testimonies, literary sources, and in the work by A. S. Pushkin, writers of his generation, formed in the process of “opening Russian history” and understanding it in the context of the Patriotic war of 1812. During the Readings participants also discussed the problems of museum business, new archival publications, issues of cinema and its reception in a modern cultural space.

AIM: This study is a preliminary study to analyze the etiology and pathophysiology of exposure to wood dust and diisocyanates in the wood processing industry in Jepara, Central Java, Indonesia. This study also provides a diagnostic evaluation of occupational asthma (OA) for ongoing exposure.

METHODS: The research method was carried out with a systematic review of various previous findings and with a preliminary study of workers in the processing industry in Jepara, Indonesia.

RESULTS: The results show that from a sample of 32 respondents who have been carried out in a wood processing factory in Jepara, it shows that the suspect OA in sanding workers by hand is 75%, with the distribution of signs and symptoms: Chest tightness and pain (90%); cough (53%); shortness of breath (50%); and wheezing (2%). From the signs and symptoms felt, workers felt a continuous increase (progressivity) of OA by 75%.

CONCLUSION: Theoretically, this preliminary study is useful to provide information about exposure to wood dust and diisocyanates as a risk factor for OA, especially among workers in the wood industry.
Le droit à être protégé : des principes aux pratiques
Authors: Avenard Geneviève
Published: June 2021

La France n’a jamais disposé d’un arsenal juridique théorique et technique aussi étoffé pour protéger les enfants contre les violences commises dans un cadre intrafamilial. Par ailleurs, la prise de conscience de notre société sur la réalité des violences à enfants, sous toutes leurs formes, s’est amplifiée dans la période récente. Pourtant, de nombreux rapports ont au cours de ces derniers mois souligné un manque d’application effective du cadre existant, qui porte directement préjudice au droit inconditionnel des enfants au respect de leur intégrité et de leur dignité, et à leur protection. Et les travaux du Défenseur des droits ont régulièrement mis en lumière un écart grandissant entre les « droits proclamés » et les « droits réels ». Cet écart s’analyse notamment comme la conséquence d’un défaut récurrent d’accompagnement opérationnel par les pouvoirs publics au déploiement de la politique de protection de l’enfance. Plus globalement, il interroge sur la considération véritable portée à l’intérêt supérieur de l’enfant.
A Bayesian level set method for an inverse medium scattering problem in acoustics
Authors: Huang Jiangfeng , Deng Zhiliang , Xu Liwei
Published: June 2021

In this work, we are interested in the determination of the shape of the scatterer for the two dimensional time harmonic inverse medium scattering problems in acoustics. The scatterer is assumed to be a piecewise constant function with a known value inside inhomogeneities and its shape is represented by the level set functions for which we investigate the information using the Bayesian method. In the Bayesian framework, the solution of the geometric inverse problem is defined as a posterior probability distribution. The well-posedness of the posterior distribution is discussed and the Markov chain Monte Carlo (MCMC) method is applied to generate samples from the posterior distribution. Numerical experiments are presented to demonstrate the effectiveness of the proposed method.
Overcomplete representation in a hierarchical Bayesian framework
Authors: Pragliola Monica , Calvetti Daniela , Somersalo Erkki
Published: June 2021

A common task in inverse problems and imaging is finding a solution that is sparse, in the sense that most of its components vanish. In the framework of compressed sensing, general results guaranteeing exact recovery have been proven. In practice, sparse solutions are often computed combining \begin{document}$ \ell_1 $\end{document}-penalized least squares optimization with an appropriate numerical scheme to accomplish the task. A computationally efficient alternative for finding sparse solutions to linear inverse problems is provided by Bayesian hierarchical models, in which the sparsity is encoded by defining a conditionally Gaussian prior model with the prior parameter obeying a generalized gamma distribution. An iterative alternating sequential (IAS) algorithm has been demonstrated to lead to a computationally efficient scheme, and combined with Krylov subspace iterations with an early termination condition, the approach is particularly well suited for large scale problems. Here the Bayesian approach to sparsity is extended to problems whose solution allows a sparse coding in an overcomplete system such as composite frames. It is shown that among the multiple possible representations of the unknown, the IAS algorithm, and in particular, a hybrid version of it, is effectively identifying the most sparse solution. Computed examples show that the method is particularly well suited not only for traditional imaging applications but also for dictionary learning problems in the framework of machine learning.
Alignment of saline springs with evaporite karst structures in northeast Alberta, western Canada: analogue for cretaceous hypogene brine seeps to the surface
Authors: Broughton Paul
Published: June 2021

Meteoric and glacial meltwater charged groundwater, mixed with dissolved salts from Devonian sources at depth, discharged as saline springs along topographic lows of the Athabasca River Valley, which downcuts into the Cretaceous Athabasca oil sands deposit in northeast Alberta, western Canada. These Quaternary saline seeps have TDS measurements, isotope signatures and other chemical characteristics indicative of the groundwater flows coming in contact with Prairie Evaporite (M. Devonian) salt beds, 200 m below the surface. Migrations up-section of groundwater with dissolved chloride and sulphate salts occurred along salt dissolution collapse breccia zones that cross-cut Upper Devonian limestone strata. Seeps discharged along the karstic Devonian limestone paleotopography, the unconformity surface flooring the Lower Cretaceous McMurray Formation. Saline to brine springs along the Athabasca River Valley have TDS measurements that can exceed 100,000 mg/L. Quaternary salt removal was insignificant compared to the voluminous removal of the 80-130 m thick salt section for 1000s km2 during the Early Cretaceous configuration of the Devonian paleotopography, which partially controlled depositional patterns of the overlying McMurray Formation, principal host rock of the Athabasca oil sands. Little is known of the storage or disposition of voluminous brines that would have resulted from this regional-scale removal of the salt beds below the Athabasca deposit during the Cordilleran configuration of the foreland Alberta Basin. Holocene dissolution trends and discharges at the surface as saline springs are proposed as a modern analogue for voluminous Early Cretaceous brine seeps to the surface along salt dissolution collapse breccia zones, concurrent with deposition of the McMurray Formation. This model links several characteristics of the McMurray Formation as responses to Aptian brine seeps to the surface. These include: (1) the emplacement of a drainage-line silcrete along the margins of the Assiniboia PaleoValley, now partially exhumed by the Athabasca River Valley, (2) distribution of brackish-water burrowing organisms, and (3) diagenesis of calcite-cemented sand intervals.

Authors: Massa T.B. , Iwassa I.J. , Stevanato N. , Garcia V.A.S. , Silva C.
Published: June 2021

This work aims to remove the oil from passion fruit seeds using ethanol as solvent and then to carry out the transesterification of the product from the extraction step (oil + ethanol). The effects of operational variables in the ultrasound-assisted extraction (UAE) were evaluated and traditional extraction was performed for comparison. The extraction product was directed to the reaction step using an enzymatic catalyst. UAE provided oil yield from 12.32 to 21.76%, and the maximum value (73.7% of the traditional extraction yield) was obtained at 60 °C and 50 min using a solvent-to-seed ratio of 4. Oil removal was favored by increases in the investigated variables. g-tocopherol, δ-tocopherol and a high concentration of polyunsaturated fatty acids were identified in the oils. The oil obtained by UAE presented higher phytosterol contents. From the reaction step, samples were obtained with higher concentrations of ethyl esters, in addition to emulsifiers (diglycerides and monoglycerides).

Authors: Karadağ A.E. , Demirci B. , Çeçen Ö. , Tosun F. , Demirci F.
Published: June 2021

The chemical compositions of the essential oils (EOs) obtained by hydrodistillation from different parts of Cnidium silaifolium ssp. orientale (Boiss.) Tutin were analyzed both by GC-FID and GC/MS, simultaneously. One hundred nine compounds representing 90.1% of the total volatiles in the EOs were identified with the main characteristic compounds α-pinene (50.3%) in the root, germacrene D (20.3%) in the fruit, and β-caryophyllene (18.7%) in the aerial parts of C. silaifolium ssp. orientale. The antimicrobial activity against human pathogenic Gram-negative and Gram-positive bacteria was evaluated by the in vitro microdilution method. Antibacterial succeptibility was observed from the root and aerial part EOs against Staphylococcus aureus (0.039 and 0.156 mg/mL, respectively); while the fruit EO was most effective against Bacillus cereus at 0.07 mg/mL. The antioxidant capacities of the EOs were also evaluated by in vitro DPPH• and ABTS•+ scavenging assays, where no significant activity was observed compared to ascorbic acid and Trolox.
Apprendre et faire apprendre un geste professionnel
Authors: Petit Lucie , Oudart Anne-Catherine
Published: June 2021

Si l’apprentissage du geste professionnel semble relever simplement de techniques d’imitation ou d’entraînement, les apports de différents travaux en ergonomie, en clinique de l’activité ou en didactique professionnelle ont mis en évidence les paramètres corporels, psychologiques et conceptuels difficilement verbalisables et explicitables, mobilisés pour réaliser le geste de manière pertinente et efficace. De ce fait, l’apprentissage du geste s’avère une activité plus complexe qu’elle n’y paraît. L’hypothèse de formation qui consiste à penser qu’il suffit de mettre les apprenants en situation de regarder et de faire pour apprendre une gestuelle efficace est alors insuffisante pour assurer la construction des compétences professionnelles. Pour illustrer nos propos, nous prenons pour exemple le geste de soudage en formation professionnelle continue. Nous verrons notamment que si lors de l’apprentissage de ce geste les dimensions corporelles et sensori-motrices prédominent, elles sont nécessaires mais pas suffisantes à l’intégration des savoirs conceptuels essentiels pour obtenir le résultat attendu.
Conception en didactique professionnelle d’une formation des tuteurs à l’activité d’observation des pratiques en éducation physique et sportive
Authors: Ciavaldini-Cartaut Solange
Published: June 2021

Cet article porte sur l’activité d’observation des pratiques d’enseignants débutants en éducation physique et sportive comme étape préalable à la tenue d’entretien de tutorat en année de professionnalisation. Sa visée exploratoire est de montrer la conception et la mise en œuvre d’une formation de formateurs fondée sur l’analyse du travail et de l’activité d’experts dans une perspective de didactique professionnelle (Orly & Vidal-Gomel, 2011 ; Pastré, 1999, 2005, 2011). Les rapports entre le style de tutorat (Clarke, 2006), le modèle opératif et la structure conceptuelle de la situation d’observation mettent en évidence certaines limites des formations traditionnelles au tutorat. Il apparaît également comme nécessaire de permettre aux tuteurs entrant en fonction de revisiter leurs propres croyances ou conceptions sur la formation au métier d’enseignant afin de reconfigurer leurs compétences acquises ou déclaratives à des fins de développement professionnel.
Comment favoriser le développement de l’activité d’enseignants en prise avec la question du bien-être animal en élevage ?
Authors: Lipp Amélie , Simonneaux Laurence
Published: June 2021

Les enseignants de disciplines technologiques agricoles, dont la zootechnie, sont confrontés à de nombreuses difficultés lors de la conception et réalisation de situations d’enseignement-apprentissage notamment à cause des profonds bouleversements en cours dans les filières agricoles (impacts environnementaux de l’élevage, enjeux éthiques, santé publique…). Notre étude vise à analyser comment le pouvoir d’agir des enseignants de zootechnie se développe lorsqu’ils se saisissent d’un objet d’enseignement tel que le bien-être animal. Elle s’appuie sur une recherche-intervention réalisée auprès de trois enseignants de zootechnie en filière bovine. Cet article se centre plus particulièrement sur notre choix d’articuler deux cadres conceptuels et méthodologiques complémentaires, la didactique des questions socialement vives (Simonneaux & Legardez, 2011) et la clinique de l’activité (Clot, 1999) afin de rendre intelligible le développement du pouvoir d’agir des enseignants. Nos résultats mettent en évidence que l’introduction des dimensions conflictuelles du bien-être animal dans le dispositif de recherche-intervention permet de rendre dicible ce qui est difficile à dire ou à faire dans les genres professionnels concernés tels que la prise en compte des émotions des animaux d’élevage. En effet, des tensions fortes dans le réel de l’activité des enseignants participant à notre étude sont liées au genre professionnel éleveur que perçoivent les enseignants et au genre professionnel enseignant de zootechnie. Nos résultats mettent en évidence une ouverture du champ des possibles favorisant une amélioration de l’efficience de leur action mais sans que soient questionnés en retour les mobiles que tentent de réaliser les enseignants.
La triple démarche de l’enseignant en contexte hypermoderne
Authors: Pachod André
Published: June 2021

Situé dans un contexte hypermoderne caractérisé par de nouveaux rapports au temps, aux autres, à soi, aux savoirs, l’enseignant est invité à activer une triple démarche. La première, de nature sociologique, le fait évoluer dans un environnement contemporain à connaître et à comprendre dans ses évolutions, ses réalités, ses attentes, ses contradictions, ses défis. La seconde démarche, d’ordre philosophique et anthropologique, situe l’enseignant devant ou face à cette hypermodernité, l’invitant à s’arrêter pour questionner l’offre éducative et retenir certaines orientations. La troisième démarche est résolument éthique : au sein de sa classe et de l’école, il agit de façon éthique en décidant de priorités au service de la réussite de l’élève.
La transmission de legs ottomans en Tunisie. La maisonnée Bū Ḥājib des années 1870 aux années 1930
Authors: Oualdi M’hamed
Published: June 2021

À travers l’étude d’une stratégie patrimoniale développée par la famille Bū Ḥājib, dans la seconde moitié du xixe siècle à Tunis, cet article explore les formes multiples de legs ottomans et de pratiques provinciales ottomanes que des sujets tunisiens continuaient à mobiliser durant les cinq premières décennies de la colonisation française de la Tunisie. Cette étude de cas démontre ainsi que les stratégies familiales développées à partir de maisonnées – si cruciales dans la vie sociale et politique des provinces ottomanes aux temps modernes – continuaient à être des lieux de transformation sociale durant la période coloniale notamment par le biais des femmes. Cette approche micro permet aussi de remettre en cause une historiographie qui n’a pensé l’histoire de cette région que par le colonial et en ne se focalisant que sur les relations entre la métropole française et les colonies maghrébines, oubliant au passage, d’autres temporalités et d’autres territoires méditerranéens tels que l’Italie, Istanbul et Le Caire qui étaient encore des lieux importants pour des sujets tunisiens à l’époque.
La lettre de suicide du Premier Ministre ‘Abd al-Muḥsin al-Sa‘dūn
Authors: Schlaepfer Aline
Published: June 2021

Plus d’une dizaine d’années après le retrait de l’administration ottomane des provinces irakiennes de l’Empire, en novembre 1929, le Premier Ministre d’Irak ‘Abd al-Muḥsin al-Sa‘dūn met fin à ses jours en se tirant une balle de cœur. Et comme ultime déclaration, il adresse à son fils ‘Alī une lettre d’adieu qu’il rédige, non pas en arabe, mais en turc ottoman. Cet article interroge les mécanismes d’élaboration d’une « mémoire d’État hachémite » sous la monarchie de Fayṣal, centrée sur une arabité en apparence homogène et immémoriale, en se demandant s’il a pu exister, dans son ombre, une multiplicité de mémoires évoluant en marge. Sur la base d’une analyse détaillée de la trajectoire politique et personnelle du Premier Ministre – entre son bagage sociopolitique turc ottoman d’une part, et les tensions récurrentes avec le leadership chiite du sud de l’Irak d’autre part – il identifie et examine les enjeux d’une politique identitaire complexe, derrière l’écran d’une arabité revendiquée. L’héritage de la langue turque : amnésie ou indifférence ?
Ghosts of Empire in Egypt
Authors: Bishop Elizabeth
Published: June 2021

This article “Ghosts of Empire in Egypte” offer a fresh approach to the Cold War. The full story of Turkey’s ambassador in Egypt and his revenge remained out of the public eye until newspapers offered full details of a plot, clearly aimed at staging: “a military coup, assassinate Gamal Abdul Nasser and other revolution leaders, and re-establishing the monarchy in Egypt.” Great Britain’s prime minister Anthony Eden concluded the maintenance of his country’s Middle Eastern interests demanded the removal of Nasser from power, planning to isolate Nasser inside Egypt, placing a “gradual squeeze on the Egyptian economy in order to ferment popular dissatisfaction with the military regime”.

Successful completion of a doctoral degree often depends on the support a candidate receives from faculty and classmates. e-portfolios are an application of social learning pedagogy that promotes collaboration among peers while simultaneously archiving an individual's academic accomplishments. In this study, 10 cohort groups of Ph.D. students at a small liberal arts university were tasked with creating and sharing an e-portfolio throughout their doctoral program. The doctors invited all current and former Ph.D. students to participate in a survey about their e-portfolio experience: a potential sample of 140 participants. Thirty-seven current or former students completed the survey. Fifty-six percent of the responses indicated a positive reaction to the e-portfolio project. Specifically, respondents stated that the e-portfolio project promoted an increased sense of self-efficacy, encouraged relationship-building within cohort groups, and helped students to develop their research agendas.

The world is shifting. The pandemic has changed paradigms, and people have reacted by trying to find solutions for problems. New challenges arise, and, more than ever, people must understand that the future depends on the way they face the present. The COVID-19 pandemic reinforced the need to collectively work in accordance to our realities. Co-creation, entrepreneurship, holistic thinking, and creativity are huge contributions that can make a difference. This chapter aims to explain and share best practices of Portugal and Brazil to mitigate COVID-19 impacts. Using primary data, a presentation is made between a varied set of measures and actions carried out by the two countries, similar in language but different in cultures and realities. The results could be practical guidelines for potential implementation elsewhere. The conclusion seems to point out that solutions require involvement for all stakeholders, with innovation and critical behaviour as means to pursue the path of sustainable development.
Significant Complex and Non-Complex Objects During COVID-19
Authors: Pandolfo Berto
Published: June 2021

If, over time, the capacity and ability to make objects is replaced with importing products from other nations; then, when international borders are restricted or even closed, the provision of goods becomes a significant challenge. Observation of the response by Australian manufacturers as they pivoted their activities to address shortages of key objects needed during the COVID-19 pandemic highlights the value of this sector in the making of objects that are both complex and not so complex. Complex objects have long been revered due to their high value, and non-complex objects are generally less valued. However, non-complex objects have an equally important role to play, as was highlighted when borders and supply chains were disrupted due to the pandemic. This chapter will shed light on how the making of objects both complex and not complex should together be supported to maintain and grow the ability and capacity for a nation to provide for its object-based needs, particularly during difficult times.

Authors: Miller Shane , Curran Kevin , Lunney Tom
Published: June 2021

The detection of unauthorised users can be problematic for techniques that are available at present if the nefarious actors are using identity hiding tools such as anonymising proxies or Virtual Private Networks (VPNs). This work presents computational models to address the limitations currently experienced in detecting VPN traffic. The experiments conducted to classify OpenVPN usage found that the Neural Network was able to correctly identify the VPN traffic with an overall accuracy of 93.71%. These results demonstrate a significant advancement in the detection of unauthorised user access with evidence showing that there could be further advances for research in this field particularly in the application of business security where the detection of VPN usage is important to an organization.

Published: June 2021

In this work, gas metal arc welding of AISI 304 stainless steel at varying compositions of argon-CO2 shielding environment was performed using an established optimum parametric combination. Thereafter, investigations on the microstructure of the welded joints and mechanical properties of the weldments were carried out. Weldments of excellent surface quality that are void of spatters and pores were obtained when the shielding gas composition (wt.%) range is between 100% argon and 75% argon - 25% CO2. Increasing percentage composition of CO2 beyond 25% resulted in irregular bead formation characterized with spatters and pores. The hardness of the welded joint became significantly high as the CO2 composition in the shielding gas increased. The highest value of 310 HV was obtained when the shielding gas composition was 5% argon- 95% CO2. The least (220 HV) was obtained when the shielding gas was 100% argon. High ultimate tensile strength (596 - 378 MPa) was achieved when the shielding gas composition range is between 100% argon and 75% argon-25% CO2. The UTS dropped significantly as the CO2 composition in the shielding gas increased beyond 25%. It decreased from 336 MPa at 70% argon-30% CO2 shielding gas composition to 133 MPa when 100% CO2 was utilized as the shielding gas. At the end, the effects of the CO2 addition and suitable composition of CO2 addition to argon shielding environment during GMAW of AISI 304 stainless steel have been established.
