On the issue of the development of mechanisms for the implementation of business models of complex processing of mineral resources
Authors:   Luzin Institute for Economic Studies of the Kola Science Centre of the Russian Academy of Sciences, Bazhutova Ekaterina A.
Published: December 2021

The importance of implementing the concept of integrated processing of mineral resources is understood by both the state and the scientific and business communities. However, the practical implementation of the concept has not yet been properly reflected in economic activity, which is determined by a number of factors, one of which is the lack of elaboration of the issue of business models and mechanisms for their implementation in modern conditions of economic development. The economic system today is characterized by many different forms and types of manifestation of entrepreneurial activity by economic entities. Determining the optimal, balanced interaction of all economic agents of the system, providing a solution to the problem of complex processing of mineral resources, is considered in this article from the point of view of analyzing the possibilities of implementing business models corresponding to the specifics of entrepreneurial activity in the regional economic system based on an algorithm developed during previous studies, on the one hand, and existing technologies for processing mineral raw materials on the other. As an example for the analysis, the Khibinsky deposit of apatite-nepheline ores of the Murmansk region was selected, which in distinguished by a variety of valuable components and a complex material composition. The result of the work was the clarification of the proposed concepts of business activity management in the Murmansk region in the form of a description of possible business models for building a mining and processing complex; the development of a mechanism for its operation based on a network interaction agreement, as a new format of contractual relations in the mining and chemical industry, which differs from standard civil contracts; and an assessment of the prospects for the implementation of such production, ensuring the complexity of the use of raw materials when involved in processing, in addition to apatite, nepheline, sphene and titanium-magnetic concentrates.
Implementation of national projects as a factor of providing favorable conditions for self-development of territorial communities of the Far North and the Arctic
Authors:   Luzin Institute for Economic Studies of the Kola Science Centre of the Russian Academy of Sciences, Kondratovich Dmitry L.
Published: December 2021

The article examines a number of aspects of the implementation of priority national projects in the context of their impact on the self-development of territorial communities of the Far North and the Arctic, as an essential element of systemic spatial regional development. Regional and municipal aspects of self-development of territorial communities of the Far North and the Arctic are largely associated with economic, social, educational, legal, cultural and other features of interaction between the public and public authorities at all levels, including through the implementation of state programs for the development of regions. The paper analyzes the specifics of national projects implemented in the Russian Federation at the level of a number of municipalities belonging to the regions of the North and the Arctic, including: a list of national projects in which the municipality participates; the main problems hindering the implementation of national projects; issues requiring priority attention from municipal authorities; an assessment of the implementation of each national project. The analysis made it possible to determine the prerequisites for the creation of effective mechanisms and tools for interaction between the government and society as a whole, which are based on state priorities related to the implementation of socially oriented development of the territories of the Far North and the Arctic and the achievement of national interests. It is established that the state has a high interest in the self-development of territorial communities, which in particular is implemented through a set of national projects aimed at providing conditions for scientific, technical and socio-economic territorial development, as well as the possibility of self-realization of each person locally and improving the quality of life of the population. It is concluded that, despite the obvious successes in the implementation of priority national projects, there are limitations associated with both objective and subjective reasons — insufficient funding, weak information support, management organization at both local and regional and federal levels.

Aplicación del método Newton-Raphson por polinomio cúbicos usando el método Tartaglia-Cardano
Authors: Echeverría Briones Fabricio
Published: December 2021

Algunos de los métodos usados para encontrar raíces de funciones en las matemáticas aplicadas son los algoritmos interactivos, que constituyen un campo de interés muy importante dentro de la disciplina debido a que permiten encontrar soluciones para usar la menor capacidad de recursos dentro de los sistemas computacionales. La propuesta de estos algoritmos iterativos implica la relación de diferentes áreas de las matemáticas: álgebra, cálculo diferencial, cálculo vectorial y análisis numérico. Esta relación conjuga la teoría de cálculo diferencial y el análisis numérico realizado por matemáticos ingleses, como Newton y Raphson. Estos propusieron la primera forma de buscar una raíz de una función usando iteraciones, la que a su vez se sustentó en teorías algebraicas desarrolladas por algunos matemáticos italianos, como Tartaglia y Cardano, quienes anteriormente habían encontrado las soluciones a las raíces de un polinomio de orden cúbico. Dentro del proceso deductivo que se siguió en el proceso, se utilizaron las aproximaciones recomendadas que se generaron al aplicar las Series de Taylor. Por otro lado, durante el proceso de experimentación se han identificado determinados patrones repetitivos, especialmente, cuando el punto de inicio se aleja de la raíz. Esto permitió mejorar el algoritmo iterativo al identificar el lugar de la curva de convergencia.  Finalmente, se generalizó la ecuación iterativa para muchas variables, a partir de las deducciones utilizadas de 1 y 2 variables.

The electroencephalogram (EEG) gained a lot of importance in recent years because of its property to depict the nature and actions of human perception. EEG signals are good at capturing the emotional state of a person by measuring the neuronal activities in different regions of the brain. Lots of EEG-based brain-computer interfaces with a different number of channels ( 62 channels, 32 channels, etc.) are being used to capture neuronal activities which can be segmented into different frequency ranges (delta, theta, alpha. beta and gamma). This paper puts forward a neural network architecture for the recognition of emotion from EEG signals and a study providing the set of brain regions and the frequency type associated with the corresponding brain region which contributes most for the detection of emotion though EEG signals. For experimentation, SEED-IV dataset has been used

Published: December 2021

The purpose of this study was to determine the variables affecting the implementation of writing skills instruction and learning in grades 7 and 8 in North Shoa Zone Second Cycle Primary schools. The study's primary purpose was to determine the difficulties encountered by English language instructors and students while teaching and learning to write in English classes. The research included the participation of 25 English language instructors and 1484 pupils from 14 Second Cycle Primary Schools. A questionnaire and an interview were used to obtain the required data. Questionnaires were completed by instructors and students, and English language teachers were interviewed. The questionnaire data was tallied and examined statistically in terms of frequency and percentage. Similarly, interview data were categorized and qualitatively characterized. The investigation revealed that the majority of instructors and students struggle with teaching and learning writing skills. Additionally, although both English instructors and students believe they are engaging in writing activities in the classroom, the students' writing performance is not as promising as shown by open-ended questions and comments from English language teachers interviewed. Several key suggestions are made in light of the results of this research in order to mitigate the issues that impede the efficient implementation of writing instruction and learning in second cycle primary schools. The primary recommendation is to offer enough training for English language instructors on how to teach writing skills, which will then be conveyed to students in order for them to enhance their writing performance.

La resistencia incompleta del café a la roya: una revisión.
Authors: Quiroga-Cardona Julio
Published: December 2021

En los programas de mejoramiento genético vegetal, los objetivos son diversos, entre ellos se encuentra eldesarrollar genotipos altamente productivos, de amplia adaptabilidad y con resistencia genética a patógenos limitantes para el cultivo. Para el caso de resistencia a enfermedades, es relativamente fácil de lograr cuando se cuenta con fuentes de genes y la expresión de estos es monogénica – dominante. En este caso, pueden obtenerse variedades con resistencia genética de tipo vertical; sin embargo, este tipo de resistencia rápidamente puede ser vencida por patotipos compatibles, y cuando esto sucede, debe recurrirse a un cambio en la estrategia, con el fin de lograr que la resistencia de plantas a patógenos perdure en el tiempo y su durabilidad se logra mediante el uso de la resistencia genética horizontal o cuantitativa. Este tipo de resistencia sólo estará presente en variedades poseedoras de diversidad genética, factor condicionante que las hace más aptas para enfrentar a futuro factores de riesgo. En esta revisión se hace una recopilación de conceptos generales, factores que afectan la resistencia y avances logrados en la comprensión de la resistencia genética de tipo horizontal de Coffea arabica L. y Coffea canephora Pierre ex Froehner.
EVOLUTIONARY GAME ANALYSIS FOR RENT-SEEKING BEHAVIOR SUPERVISION OF MAJOR INFRASTRUCTURE PROJECTS BASED ON PROSPECT THEORY
Authors: Lv Lelin , Li Huimin Li , Wang Zhuofu , Zhang Chengyi , Qiao Ran
Published: December 2021

Major infrastructure projects (MIPs) possess significant strategic positions in the national economy and social development. However, recently, the rent-seeking behavior between supervision units and project contractors has intensified in project construction. This paper aims to study the behavior decision-making of stakeholders in rent-seeking behavior supervision system of MIPs. In the complex and uncertain environment of MIPs, game players have cognitive bias and value perception preference. Therefore, this study introduced prospect theory and constructed the perceived return matrix and evolutionary game model of MIP rent-seeking behavior supervision among project owners, supervision units, and project contractors. From the perspective of risk perception theory, the reasons for the behavioral tendencies of game participants and the conditions for the steady state of strategy selection were explored through system dynamics simulations. The results showed that the stable state of the optimal strategy in the rent-seeking behavior supervision system of MIPs is related to the cognitive bias of the game players and is influenced by the level of regulation cost, the intensity of punishment and the size of accident losses. The contribution of this study lies in providing theoretical basis and decision support for constructing a long-term preventive mechanism for rent-seeking activities in MIPs.
PROFIT DISTRIBUTION IN IPD PROJECTS BASED ON WEIGHT FUZZY COOPERATIVE GAMES
Authors: Guo Shuwen , Wang Junwu
Published: December 2021

Integrated Project Delivery (IPD) is regarded as an effective project delivery method that can deal with the challenge of the rapid development of the architecture, engineering, and construction (AEC) industry. In the IPD team, the alliance profit is not distributed fairly and effectively due to uncertainty, preventing the achievement of the IPD project goals. This study focuses on optimizing the profit distribution among stakeholders in IPD projects and uses quadratic programming models to solve fuzzy cooperative games in the IPD. A payoff function is used in the fuzzy alliance to determine the characteristics of the interval-valued fuzzy numbers, and different weights of the alliance and the efficiency of the player’s participation in the IPD are considered in the profit distribution. A case study is conducted, and the results of the proposed method are compared with those of crisp cooperative games. The results show that the fuzzy cooperative game increases the profit of participants in IPD projects. It is more practical to use weight fuzzy cooperative games than crisp games to express imputation. Moreover, the quadratic programming models and methods result in a fair and efficient profit distribution scheme in IPD projects.
CDFS-6664: A Candidate of Lyman-continuum Emission at z ∼ 3.8 Detected by the Hubble Deep UV Legacy Survey
Authors: Yuan Fang-Ting , Zheng Zhen-Ya , Lin Ruqiu , Zhu Shuairu , Rahna P. T.
Published: December 2021

We report the detection of Lyman continuum (LyC) emission from the galaxy, CDFS-6664, at z = 3.797 in a sample of Lyman break galaxies with detected [O iii] emission lines. The LyC emission is detected with a significance ∼5σ in the F336W band of the Hubble Deep UV Legacy Survey, corresponding to the 650–770 Å rest frame. The light centroid of the LyC emission is offset from the galaxy center by about 0.″2 (1.4 pkpc). The Hubble deep images at longer wavelengths show that the emission is unlikely provided by low-redshift interlopers. The photometric and spectroscopic data show that the possible contribution of an active galactic nucleus is quite low. Fitting the spectral energy distribution of this source to stellar population synthesis models, we find that the galaxy is young (∼50 Myr) and actively forming stars with a rate of 52.1 ± 4.9 M
⊙ yr−1. The significant star formation and the spatially offset LyC emission support a scenario where the ionizing photons escape from the low-density cavities in the ISM excavated by massive young stars. From the nebular model, we estimate the escape fraction of LyC photons to be 38% ± 7% and the corresponding intergalactic medium (IGM) transmission to be 60%, which deviates more than 3σ from the average transmission. The unusually high IGM transmission of LyC photons in CDFS-6664 may be related to a foreground type-2 quasar, CDF-202, at z = 3.7, with a projected separation of 1.′2 only. The quasar may have photoevaporated optically thick absorbers and enhance the transmission on the sightline of CDFS-6664.

Authors: Goranov Georgi , Nikolov Petar
Published: December 2021

Backgrounds and purpose: To analyse the periprocedural CAS complications in patients with concomitant coronary disease. Material and methods: A prospective study analysed the frequency and characteristics of periprocedural complications after CAS in 329 patients, of whom 62.2% had symptomatic carotid stenosis > 50% and 37.8% had asymptomatic > 70%. The mean age was 70.2 (45-88) years, male/female ratio – 253/76. The degree of carotid stenosis was assessed angiographically according to NASCET criteria and was stratified by a newly proposed carotid score in three risk groups. Distal embolic protection was used in all patients. Results: Periprocedural complications were observed in 25/349 CAS interventions: TIA – 4.9%, major stroke – 0.6%, minor stroke – 1.4%, hyperperfusion syndrome – 0.3%. No MI and death were registered. Out of more than 20 factors analysed, previous MI (χ2 = 7,707; p = 0.021) and stroke (χ2 = 9,835, p = 0.043), “slow flow” (χ2 = 3.752; p = 0.001), residual stenosis> 20% (χ2 = 13.752; p = 0.001), radiation time (F = 13.323; p = 0.000), the amount of contrast used (F = 5.297; p = 0.006), contrast- induced OBN (χ2 = 25.845; p = 0.000), females with CKD (χ2 = 8.681; p = 0.013) or with a high carotid score (χ2 = 7.329; p = 0.026) were found to be predictors of complications. Conclusion: CAS is a safe procedure with low risk of MI and death in patients with concomitant coronary disease.
Effects of Vitamin E Supplementation to Metabolic Markers on Diet-Induced Obesity in Mice 
Authors: Megawati Eka Roina , Lubis Lokot Donna , Harahap Febi Yanti
Published: December 2021

Introduction: Obesity creates health problems by increasing the risks of chronic diseases such as type 2 diabetes and cardiovascular disorders. Obesity leads to insulin resistance, higher blood glucose and cholesterol levels. Adipose tissues synthesize adiponectin which acts as anti-inflammatory, antidiabetic, and anti-atherogenic agent. Meanwhile, vitamin E is an antioxidant that acts as an anti-inflammation.

Aim: The purpose of this study was to analyze the effects of vitamin E supplementation to metabolic markers on diet-induced obesity in mice.

Materials and methods: Twenty-four mice (Mus musculus, L) aged four weeks were divided into six groups which were fed different diets and given vitamin E in different dosages or methods. The period of treatment was 18 weeks. The mice body weights were measured every week; blood sugar and cholesterol levels were measured every six weeks, and the adiponectin level measurement was done at week 18.

Results: A repeated measures ANOVA showed that body weight and cholesterol level within groups were not significantly different [F(15, 54)=1.417, 0.173 and F(10, 36)=1.391, 0.224 respectively]. The glucose levels were found to be significantly different [F(7.646, 27.526)=2.625, 0.030]. There was no significant difference in the adiponectin levels.

Conclusions: Vitamin E supplementation could not prevent the increase of body weight, the elevation of blood sugar and cholesterol levels, and also could not increase adiponectin level.
Melatonin and Epilepsy
Authors: Vasileva Zdravka
Published: December 2021

Epilepsy is a chronic neurological disease with recurrent seizures. Its incidence, the social and psychological aspects of epilepsy-associated stigmatization in society, the medical risk of severe seizures, and the challenges in treatment confirm its medical and social significance. The pathogenesis of the diseases is associated with abnormal activity of a population of neurons due to various mechanisms, the most frequent being oxidative stress, glutamate excitotoxicity, and mitochondrial dysfunction. In the last 3-4 decades, the possible connection between epilepsy and melatonin – a neurohormone secreted by the pineal gland – has been sought and studied. Various physiological functions of melatonin in humans have been proven – regulation of circadian rhythms (diurnal, seasonal), sleep and wakefulness, participation in the processes of thermoregulation, tumour growth and aging, sexual activity and reproductive functions. It also has immunomodulatory, cytoprotective and antioxidant activity. The results from the studies with experimental models with animals conducted so far in search of a correlation between melatonin and epileptogenesis are mainly in support of the hypothesis of its anticonvulsant effect. The studies with humans are diverse in design, with a smaller number of participants, and the results are not always in explicit support of this hypothesis. The correlation between melatonin concentration and the course of the disease in patients with epilepsy has been discussed. The possibility of adding melatonin to anti-epileptic therapy has also been studied recently.
A Comparative Study on Intranasal Versus Intravenous Lorazepam in the Management of Acute Seizure in Children
Authors: Rudra Nandan , Ghosh Taraknath , Roy Uttam Kumar
Published: December 2021

Introduction: The acute seizure in childhood is a medical emergency which is usually managed by benzodiazepines used as a first line of therapy. There are no strict guidelines of using intranasal lorazepam in India. Many paediatricians use it in an emergency situation as it is inexpensive, easy to administer and even treatment can be started at home. Very few studies are available to compare efficacy and safety of intravenous lorazepam with intranasal lorazepam in childhood seizure, though both routes have comparable pharmacokinetic profile. Intravenous lorazepam (0.1 mg/kg) is already recommended as a first-line treatment of acute childhood seizures in India. There are very few studies regarding the usefulness of intranasal lorazepam. With this background, we compared intranasal lorazepam with the more widely accepted intravenous lorazepam for control of acute seizure.

Aim: To compare effectiveness and safety of intranasal and intravenous lorazepam in acute seizure in children aged 5-12 years.

Materials and methods: This is an analytical observational cross-sectional study involving patients with acute seizure who received lorazepam via either the intravenous or intranasal route. Formulation and dosage of lorazepam were the same in both routes.

Results: Distributions of patient groups according to sex, age, and weight were statistically not significant (p=0.42, p=0.391, and p=0.605, respectively). Time to control seizure within 10 min and persistent cessation of seizure activity were similar in both groups. Safety parameters showed no differences statistically.

Conclusions: Though intravenous lorazepam is recommended as first-line treatment, intranasal lorazepam may be a good alternative choice in a convulsing child.

Introduction: Dyslipidemia is one of the most common metabolic disorders. Vitamin D is one of the essential fat soluble vitamins which has many functions in the human body.

Aim: The aim of this study was to evaluate the association between dyslipidemia and vitamin D deficiency.

Materials and methods: This is a cross-sectional study which included 130 participants (58 males and 72 females) aged between 20-70 years and conducted between June 1 and October 30, 2020. The level of vitamin D was determined for each participant; we also measured the serum levels of cholesterol, triglyceride, high density lipoprotein, and low density lipoprotein.

Results: There were 79 persons with vitamin D deficiency, 21 persons were vitamin D insufficient, and 10 - vitamin D sufficient. There were significant differences in the level of cholesterol, triglycerides, high-density and low-density lipoproteins according to the level of vitamin D.

Conclusions: Deficiency of vitamin D has a negative impact on the levels of cholesterol, triglycerides, high-density and low-density lipoproteins.
Intraductal Papillary Mucinous Neoplasm of the Pancreas: Need for a Tailored Approach to a Rare Entity
Authors: Konaktchieva Marina , Penchev Dimitar , Popivanov Georgi , Vladova Lilia , Cirocchi Roberto , Penkov Marin , Karagyozov Petko , Mutafchiyski Ventsislav
Published: December 2021

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a relatively new entity that has gained increased attention because of its unique features – presence of different subtypes with different malignant potential, biological behavior, and prognosis, higher rates of recurrences and concomitant or metachronous pancreatic duct cancer. It is rare with an incidence of 4 to 5 cases per 100 000. The relative lack of experience significantly hampers decision making for surgery (pancreatic head resection, distal pancreatectomy or enucleation) or follow-up.

Herein we present two cases managed by diametrically different tactic according to the risk stratification – distal pancreatectomy with splenectomy and observation, respectively. An up-to-date literature review on the key points in diagnostics, indications for surgery, the extent of surgery, follow-up, and prognosis is provided.

The tailored approach based on risk stratification is the cornerstone of management. Absolute indications for surgery are the lesions with high-risk stigmata, whereas the worrisome features should be evaluated by endoscopic ultrasound and fine-needle aspiration. Main duct and mixed type are usually referred to surgery, whereas the management of a branch type is more conservative due to the lower rate of invasive cancer. Strict postoperative follow-up is mandatory even in negative resection margins due to a high risk for recurrences and metachronous lesions.

Despite the guidelines, the intraductal papillary mucinous neoplasm remains a major challenge for clinicians and surgeons in the balance the risk/benefit of observation versus resection. Risk stratification plays a key role in decision-making. Future trials need to determine the optimal period of surveillance and the most reliable predictive factors for concomitant pancreatic duct cancer.

Authors: Pelcaru Cristina Florentina , Alistar Alexandru
Published: December 2021

This paper confirms the presence of steppe polecat Mustela eversmanii in Giurgiu County after more than 50 years. Mustela eversmanii is considered a vulnerable species, being listed in Annexes II and IV of the Habitats Directive. The specimen was found within the Site of Community Importance - ROSCI0043 Comana, included in the Natura 2000 network, which significantly overlaps with the protected natural area (Comana Natural Park). Currently, the steppe polecat is not added to the list of the Standard Form, because its presence was uncertain. We consider that this discovery is valuable and has important implications for the conservation of the species.

Vérité et perspectivisme selon Nietzsche
Authors: Benoit Blaise
Published: December 2021

Le perspectivisme nietzschéen se situe-t-il « après la vérité » ? Si Nietzsche critique le concept même de vérité, il emploie pourtant très régulièrement cette expression, jusque dans Ecce homo et L’Antéchrist . Prendre acte de cette tension est insuffisant : y a-t-il contradiction ou s’agit-il plutôt de polysémie ? Cette étude, qui distingue chemin faisant perspectivisme et relativisme, procède à l’examen des différents sens de « vérité » dans l’œuvre de Nietzsche afin de construire une réponse à ce problème.
Dimension sociétale du phénomène Jeanne-Calment : mythe moderne ?
Authors: Allard Michel
Published: December 2021

Nous postulons que Jeanne Calment constitue un mythe moderne vecteur de nombreux stéréotypes comme l’allongement de l’espérance de vie, la concrétisation effective et personnalisée d’un changement de paradigme, la consécration du standard français comme modèle de longévité (spécialement féminin). La construction de la célébrité n’a été possible qu’en raison de circonstances très particulières : la durée du règne de la doyenne de l’humanité, la validation très solide de son âge, la concordance entre la « vraie » Jeanne Calment et le personnage que les médias ont créé et entretenu. Cet article propose de revenir sur la genèse de ce mythe moderne.
Généalogie de la famille Calment
Authors: Bisson Boyer Caroline
Published: December 2021

Le 14 février 1991, la Française Jeanne Calment détient le titre de nouvelle doyenne mondiale. L’authentification de la longévité exceptionnelle de cette femme exigeait d’obtenir un maximum de preuves légitimes et incontestables de son existence. Une recherche généalogique était essentielle pour vérifier qu’il n’existe aucune imposture, afin d’exclure tout homonyme, principalement plus jeune. Cette étude nécessite une connaissance approfondie de toutes les sources légales disponibles afin de les analyser. La France est un pays possédant depuis des siècles des archives de qualité, notamment les registres paroissiaux et civils. Aussi, en exploitant les données de tous ces documents, il est possible de prouver l’identité d’une personne depuis sa naissance jusqu’à sa mort. L’enquête sur la personne de Jeanne Calment, au fil du temps, fut alors facilitée par un fait significatif : elle vécut toute sa vie dans sa ville natale d’Arles, comme le reste de sa famille. Ainsi, à partir des nombreuses données recueillies, l’étude démographique comparant la longévité des membres appartenant aux multiples branches familiales de cette doyenne à celle d’un échantillon de la population locale a été facilement réalisée.
À propos de « super-vieillissement ». Idéalisation, hypomanie, renoncement
Authors: Verdon Benoît , Rexand-Galais Franck
Published: December 2021

La psychologie clinique du vieillissement permet de dresser un tableau du grand âge bien plus contrasté que celui proposé par les tenants de l’idéologie du super-vieillissement. Deux cas cliniques, celui d’un centenaire très sthénique résidant en institution et celui d’une femme hyperactive d’un peu plus de 50 ans, permettent d’aborder le sens du maintien à tout prix de la performance dans le vieillissement. Si l’existence de potentialités humaines sortant de l’ordinaire, support de toutes les convoitises et de tous les fantasmes de généralisation, n’est pas rejetée, l’exigence de l’endurance et de l’exceptionnel, si souvent portée par les médias, vient questionner le fonctionnement psychique de ceux qui se l’approprient au-delà d’une certaine dose où le raisonnable se fait porteur d’élan. L’idéalisation de la performance, l’arrogance de l’exception, le mépris de la différence et du handicap, le déni de la perte et du manque, une tentative de défense contre une dépressivité consécutive aux altérations et un refus de la mort ressortent comme des motifs communs de cette identification individuelle au super-vieillissement.
Clinique du chaos et soins palliatifs
Authors: Mallet Donatien
Published: December 2021

Alors que nous sommes soumis depuis 2020 à un enchainement de vagues virales désorganisant notre quotidien, voilà que le terme « chaos » revient dans le langage courant, comme venant nommer le monde que nous découvrons, ou plutôt redécouvrons. Car le chaos ne nous est pas si étranger. C’est à partir d’une expérience professionnelle auprès des personnes atteintes de maladies graves que nous proposons d’explorer ce thème. Dans cette démarche, nous nous appuierons sur une pratique soignante, reconnue sous les termes de « soins palliatifs », et chercherons à dégager des points de repères pour faire face au chaos, ou plutôt continuer d’être dans le chaos. Sur le plan philosophique, nous nous inspirerons de Friedrich Nietzsche car ce philosophe offre des renversements de perspectives pertinents pour aborder ce qui semble être un socle fondateur de notre humanité.
Légitimation du théâtre à machines et transfert du savoir technique (1630-1650)
Authors: Visentin Hélène
Published: December 2021

S’interrogeant sur les conditions matérielles du théâtre dans la première moitié du xvii e  siècle, cet article montre que la pratique du théâtre à machines, loin d’être marginale, est centrale à la politique culturelle du cardinal de Richelieu et indissociable de ses activités politiques. À partir d’une étude de cas – Mirame  (1641) de Desmarets de Saint-Sorlin –, il s’agit de comprendre le processus de légitimation du théâtre à machines qui passe à la fois par un transfert du savoir-faire technique entre l’Italie et la France et par un processus de traduction culturelle de ce savoir.
Naissance de la machine médiatique : théâtre et supports publicitaires, d’ Andromède à La Devineresse
Authors: Schuwey Christophe
Published: December 2021

L’histoire des spectacles équivaut largement à celle de leur publicité : la majeure partie des documents dont on dispose aujourd’hui était à l’origine des discours à vocation promotionnelle. Partant de ce constat, cet article retrace le développement et l’évolution de la machine publicitaire. Dans quels espaces, sur quels supports a-t-on promu le théâtre et comment ces différents médias ont-ils façonné la forme et le contenu de cette promotion ? Comment les besoins publicitaires des différents genres théâtraux (notamment les pièces à machines) ont-ils fait évoluer l’édition théâtrale ; corollairement, comment l’apparition de ces nouveaux supports a-t-elle modifié les formes du discours promotionnel ? Et, surtout, dans quelle mesure cette évolution a-t-elle déterminé les documents dont nous disposons aujourd’hui pour écrire l’histoire des spectacles ?
Aider ceux qui ne l’ont pas (vraiment) demandé : le travail d’un SASE
Authors: Messaoudi Fadoua
Published: December 2021

À partir de la situation de la famille Demol, tirée des résultats d’une recherche doctorale en cours, je propose dans cet article de montrer comment les intervenants sociaux d’un service d’accompagnement socioéducatif (SASE) de Bruxelles s’emploient à intervenir auprès d’un public qui ne l’a pas (vraiment) demandé. Je confronte la thèse d’une « autonomie-condition » (Ehrenberg, 2012) à la façon dont elle est pratiquée en situation. Pour cela, je montre d’abord comment les pratiques des intervenants sociaux sont affectées par la nature de la relation qui les lie à leur public ; j’expose ensuite comment ils cherchent à intervenir pour induire un changement chez les bénéficiaires, en (ré)interprétant en permanence à qui ils ont affaire ; je présente enfin, à l’aide de la métaphore d’un match de football mobilisé par Norbert Elias, comment par ce travail de repérage ils se repèrent en fait au sein d’une « configuration ».
La plateformisation est-elle compatible avec l’exercice discrétionnaire ?
Authors: Decamp André
Published: December 2021

La mise en place du programme Action Publique 2022 met en lumière la redéfinition de la protection sociale et celle des relations de l’État avec les usagers, par le biais de la dématérialisation du Service public. Les agents du travail social voient leur pouvoir discrétionnaire pris en étau entre le big data et la plateformisation du service public. Quel est l’effet de la plateformisation et de ce big data sur les marges de manœuvres des fonctionnaires du travail social, leurs pratiques de contrôle et leur processus décisionnel ? Ce projet de programme gouvernemental Action Publique 2022 donne l’opportunité d’explorer les pistes de réponses à ces questions, et d’analyser la place actuelle de l’usager ainsi que les notions d’enjeux du numérique et du glissement progressif de la notion de « risques ».
Bilan de compétences et travail soutenable
Authors: Laloy David
Published: December 2021

L’article propose d’analyser, à travers le prisme du concept de travail soutenable, le bilan de compétences, un dispositif d’accompagnement individuel à l’orientation et à l’évolution professionnelle. Ce concept a une portée heuristique pour comprendre ce que vivent les travailleurs dans ce cheminement de questionnement et d’orientation professionnelle. L’auteur s’appuie sur les résultats d’une évaluation du bilan de compétences qu’il mène depuis de nombreuses années. Après une discussion et une présentation de la genèse du concept de travail soutenable, il décrit le bilan de compétences, ses objectifs, son mode de fonctionnement. Enfin, à partir des données récoltées dans le cadre de l’évaluation, il montre ce qui rend le travail « non-soutenable » et en quoi le bilan de compétences permet d’outiller le travailleur pour s’inscrire dans un parcours professionnel davantage soutenable.
Sur la contention et la contrainte en psychiatrie
Authors: Engel Céline , Maugiron Philippe , Gross Olivia
Published: December 2021

Les auteurs mentionnent trois lois majeures, adoptées en ce début de XXIème siècle. La loi de 2002 oblige à un consentement libre éclairé pour les actes et traitements proposés. Celle de 2005 reconnaît le handicap psychique, ainsi que l’égalité des droits et des chances de participation à la citoyenneté. Enfin, la loi de 2011, spécifique à la psychiatrie, réforme le dispositif d’hospitalisation sous contrainte. Ils constatent un recours excessif à la contention et à la contrainte, tout en décrivant des effets semblables entre contention physique et camisole chimique. Il convient de rapporter cette situation à son contexte, caractérisé par une contradiction. D’une part, la demande du nombre de personnes concernées par les soins croît et, d’autre part, les moyens pour y répondre décroissent. Une double conséquence en résulte : réduction du temps de soin par la parole et augmentation du recours à l’hospitalisation sous contrainte. Les trois auteurs ne s’en tiennent pas à ce constat. Ils proposent une alternative aux multiples aspects : groupes d’entraide mutuelle, pair-aidance, directives anticipées en psychiatrie, autonomisation par les programmes de rétablissement. Les conditions de leur succès dépendant à la fois d’une modification de l’opinion publique et de l’engagement tant des professionnels que des personnes concernées.
Silent Herding in Initial Public Offering (IPO) Reluctance: Evidence from Developing Countries
Authors: Simo Landry , Nzongang Joseph , Álvarez-Otero Susana
Published: December 2021

Cet article vise à mettre en évidence les fondements psychologiques de la prise de décisions financières des managers d’entreprises, eu égard à la réticence à l’introduction en bourse. 67 entretiens approfondis ont été menés dans le cadre d’une analyse phénoménologique constructiviste, combinée à des modèles de régression et logit/probit. Les résultats montrent que la réticence des managers vis-à-vis des marchés boursiers est motivée par le mimétisme silencieux. Cet article fournit les premières preuves empiriques du mimétisme silencieux dans la littérature économique et contribue donc à l’enrichissement du champ théorique de la finance comportementale et celui de la prise de décision en matière d’introduction en bourse. D’un point de vue pratique, cet article formule à l’endroit des pouvoirs publics, des recommandations à mettre en œuvre dans le cadre des politiques d’incitation à l’introduction en bourse.
Strategies for fostering emotional intelligence among organizational leaders
Authors: Garza Astrid , Salcedo Jorge
Published: December 2021

À l’heure actuelle, les dirigeants des organisations rencontrent différents défis et, pour cette raison, certains traits sont nécessaires pour qu’un leadership efficace ait lieu. L’intelligence émotionnelle (IE) a pris de l’importance dans le secteur organisationnel. En conséquence, la formation des dirigeants organisationnels actuels et des futurs dirigeants organisationnels sur l’intelligence émotionnelle est nécessaire. Le but de cette recherche appliquée qualitative était d’en apprendre davantage sur les aspects les plus importants à prendre en compte lors de la conception d’un programme de formation à l’intelligence émotionnelle qui pourrait être mis en œuvre parmi les dirigeants de Monterrey, le Mexique et l’Amérique latine. Les programmes de formation existants sur l’intelligence émotionnelle ont été analysés et les experts ont été interrogés pour la collecte de données.
A virtual element generalization on polygonal meshes of the Scott-Vogelius finite element method for the 2-D Stokes problem
Authors: Manzini Gianmarco , Mazzia Annamaria
Published: December 2021

The Virtual Element Method (VEM) is a Galerkin approximation method that extends the Finite Element Method (FEM) to polytopal meshes. In this paper, we present a conforming formulation that generalizes the Scott-Vogelius finite element method for the numerical approximation of the Stokes problem to polygonal meshes in the framework of the virtual element method. In particular, we consider a straightforward application of the virtual element approximation space for scalar elliptic problems to the vector case and approximate the pressure variable through discontinuous polynomials. We assess the effectiveness of the numerical approximation by investigating the convergence on a manufactured solution problem and a set of representative polygonal meshes. We numerically show that this formulation is convergent with optimal convergence rates except for the lowest-order case on triangular meshes, where the method coincides with the \begin{document}$ {\mathbb{P}}_{{1}}-{\mathbb{P}}_{{0}} $\end{document} Scott-Vogelius scheme, and on square meshes, which are situations that are well-known to be unstable.
Numerical preservation issues in stochastic dynamical systems by $ \vartheta $-methods
Authors: D'Ambrosio Raffaele , Di Giovacchino Stefano
Published: December 2021

This paper analyzes conservation issues in the discretization of certain stochastic dynamical systems by means of stochastic \begin{document}$ \vartheta $\end{document}-mehods. The analysis also takes into account the effects of the estimation of the expected values by means of Monte Carlo simulations. The theoretical analysis is supported by a numerical evidence on a given stochastic oscillator, inspired by the Duffing oscillator.
