Post-stroke aphasia recovery: actual understanding, future perspectives
Authors:   Neurology Department, University Emergency Hospital, Bucharest, Romania, Marinescu Doina Carmen
Published: October 2022

Post-stroke aphasia is a frequent encounter, with 20 – 30% of ischemic stroke patients affected; despite classical recovery attempts, 10 – 15% of these will still have a severe form of aphasia at 6 months. Its presence greatly impedes both motor recovery and post-stroke quality of life. With stroke as one of the leading causes of disability worldwide, improved understanding of spontaneous recovery mechanisms and adequate, tailored intervention could represent important ways of limiting personal, social and economic costs in such patients.

Pathogenesis of spontaneous carotid artery dissection (sCAD) is still a domain of research. Classical inherited connective tissue disease, primary or systemic arteriopathies and ultrastructural alterations of the arterial wall were reported in sCAD. We report a case of sCAD in a middle-aged woman with dystrophic epidermolysis bullosa, an inherited blistering disease due to a deficiency of type VII collagen at the basement membrane zone (BMZ).

During dentition development stages, various defects of the dental structures can appear and can be in shape, number, position, structure. The latter primarily affect the aesthetic appearance, but also the other functions of the dentomaxillary system, when the severity of the lesions is important. Enamel hypoplasia in the frontal area of dental arches, with moderate extension of defects, can be easily treated with modern resin composite materials using adhesive technique, by direct restorations. In this way, the coronal morphological integrity and the harmonious dento-facial appearance are restored. Restorations for this type of dental lesions need to be carefully monitored and retreatment performed if necessary.
FUNCTIONING OF THE RUSSIAN PARTICIPLES IN PUBLICISTIC TEXTS
Authors: Аносова Анастасия Александровна
Published: October 2022

В статье представлены результаты сопоставительного анализа употребления причастных словоформ в новостном и аналитическом жанрах публицистического стиля русского языка. Исследование проведено на материале новостных заметок и аналитических статей электронных версий газет «Известия» и «Московский Комсомолец», а также новостных сайтов interfax.ru и rbc.ru. Внимание сосредоточено на выявлении частотности употребления разных видов причастий в новостных заметках и аналитических статьях, рассмотрении явления адъективации причастий в данных типах текстов. Анализ текстов информационных и аналитических жанров показал, что в новостных заметках наиболее широкое применение получили пассивные конструкции с использованием кратких страдательных причастий. В текстах обоих жанров преобладают двучленные пассивные конструкции. Среди субстантивированных причастий наиболее частотны субстантиваты среднего рода прилагательного склонения, обозначающие отвлеченные понятия, а также одушевленные субстантиваты с собирательным значением. Одиночные причастия в функции определения, стоящие перед определяемым словом, имеют тенденцию к адъективации. В аналитических текстах адъективации чаще всего подвергаются действительные причастия настоящего времени в метафорическом и переносном значениях, в то время как в информационных текстах наибольший процент адъективированных причастий - это страдательные причастия прошедшего времени со стертыми значениями.

The article presents the results of the comparative analysis of the use of participle forms in the information and analytical genres in the publicistic style of the Russian language. The research has been made using the news and analytical articles from electronic versions of Russian daily newspapers “Izvestia” and “Moskovskij Komsomolets” and news sites interfax.ru and rbc.ru. The attention is focused on determining the frequency of using different participle forms in the news and analytical texts, examining of adjectivization of participles in the given types of texts. The analysis of information and analytical texts has shown that passive structures with short forms of participles are most frequently used in the news articles. Binominal passive structures dominate in the texts of both genres. Among substantivized participles, most frequently used forms are substantivized participles of neuter gender denoting abstract notions and animate substantivized participles meaning collective notions. Single participles in attributive function which precede a defined word tend to be adjectivized. Active present participles in a metaphorical and figurative meanings are adjectivized in analytical texts, while past passive participles with erased meanings are adjectivized in the news articles.
LEXICAL AND SEMANTIC MICROFIELD “D. TRUMP AS A PARTICIPANT IN THE 2020 US PRESIDENTIAL CAMPAIGN” (IN THE AMERICAN MEDIA)
Authors: Гурьянова Татьяна Юрьевна , Зайцева Елена Львовна , Билан Ольга Александровна
Published: October 2022

Настоящая статья посвящена языковой репрезентации прошедших президентских выборов в американских СМИ и нацелена на анализ языковых фактов, в которых манифестируется отношение к кандидату на пост президента США - Д. Трампу. Статьи о выборах президента всегда характеризуются различной степенью оценочности, т. е. в условиях конкуренции кандидатов и определенного ограниченного количества избирателей отрицательная и положительная оценка кандидатов вербализуется посредством языковых средств, уже имеющих оценочный компонент в значении, или же оценка может возникать контекстуально. Языковые факты, в которых проявляется негативное отношение к Д. Трампу, численно преобладают по сравнению с примерами, в которых Д. Трамп оценивается положительно. Оценочная сторона дискурса президентской кампании проявляется в виде парной структуры, в которой негативная оценка нечестного/глупого/жадного Д. Трампа, его стремление к наживе/прибыли при минимальном словесном уважении к нему в дискурсе подается на фоне языковых фактов, в которых описывается компетентность/честность/опытность Дж. Байдена. Авторы приходят к выводу, что негативное отношение к Д. Трампу в период выборов отличается использованием более разнообразных языковых средств по сравнению с его положительной оценкой.

This article is devoted to the linguistic representation of the past presidential elections in the American media and is aimed at analyzing the linguistic facts in which the attitude towards the candidate for the US presidency, D. Trump, is manifested. Articles on presidential elections are always characterized by varying degrees of evaluativeness, i.e., in the conditions of competition between candidates and a certain limited number of voters, negative and positive evaluations of candidates are verbalized with the linguistic means that already have an evaluative component in the meaning, or the evaluation may arise contextually. Linguistic facts in which a negative attitude towards D. Trump is manifested numerically predominate in comparison with the examples in which D. Trump is evaluated positively. The evaluative side of the discourse of the presidential campaign manifests itself in the form of a paired structure, in which a negative evaluation of the dishonest/stupid/greedy D. Trump, his desire for profit with minimal verbal respect for him is presented in the discourse against the background of linguistic facts describing the competence/honesty/experience of J. Biden. The authors come to the conclusion that the negative attitude towards D. Trump during the election campaign is distinguished by the use of more diverse linguistic means compared to his positive evaluation.
Testing Strong Gravitational Lensing Effects of Supermassive Compact Objects with Regular Spacetimes
Authors: Kumar Jitendra , Ul Islam Shafqat , Ghosh Sushant G.
Published: October 2022

We compare and contrast gravitational lensing, in the strong field limit, by the photon sphere in spherically symmetric regular electrically charged (REC) black holes (0 < b ≤ b

E
) and with those by corresponding REC no-horizon spacetimes (b > b

E
). Here, b is an additional parameter due to the charge and the value b = b

E
≈ 0.226 corresponds to an extremal black hole with degenerate horizons. Interestingly, the spacetime admits a photon sphere for 0 < b ≤ b

P
≈ 0.247 and an anti-photon sphere only for b

E
< b ≤ b

P
. With no-horizon spacetime, images by lensing from the inside of the photon sphere (u < u
ps) can also appear. Interestingly, for the case of u < u
ps the deflection angle α

D
increases with u. We analyze the lensing observables by modeling compact objects Sgr A*, M87*, NGC 4649, and NGC 1332 as black holes and no-horizon spacetimes. The angular position θ
∞ and photon sphere radius x
ps decrease with increasing parameter b. Our findings suggest that the angular separations (s) and magnification (r) of relativistic images inside the photon sphere may be higher than those outside. Moreover, the time delay for Sgr A* and M87* can reach ∼8.8809 and ∼12,701.8 minutes, respectively, at b = 0.2, deviating from Schwarzschild black holes by ∼2.615 and ∼4677 minutes. These deviations are insignificant for Sgr A* because it is too small, but they are sufficient for astronomical observation of M87* and some other black holes. With EHT bounds on the θ
sh of Sgr A* and M87* within the 1σ region, placing bounds on the parameter b, our analysis concludes that REC black holes agree with the EHT results in finite space, whereas the corresponding REC no-horizon spacetimes are completely ruled out.
Effects of Radiative Diffusion on Dynamical Corotation Torque in Three-dimensional Protoplanetary Disks
Authors: Yun Han-Gyeol , Kim Woong-Tae , Bae Jaehan , Han Cheongho
Published: October 2022

The dynamical corotation torque arising from the deformation of horseshoe orbits, along with the vortensity gradient in the background disk, is important for determining the orbital migration rate and direction of low-mass planets. Previous two-dimensional studies have predicted that the dynamical corotation torque is positive, decelerating inward planet migration. In contrast, recent three-dimensional studies have shown that buoyancy resonance makes the dynamical corotation torque negative, accelerating inward migration. In this paper, we study the dependence of the dynamical corotation torque on thermal transport, using three-dimensional simulations. We first show that our results are consistent with previous three-dimensional studies when the disk is fully adiabatic. In more realistic radiative disks, however, radiative diffusion suppresses buoyancy resonance significantly, especially in high-altitude regions, and yields a positive dynamical corotation torque. This alleviates the issue of rapid migration being caused by the negative dynamical corotation torque in adiabatic disks. Our results suggest that radiative diffusion, together with stellar irradiation and accretion heating, are needed to accurately describe the migration of low-mass planets.

We measure homogeneous distances to M31 and 38 associated stellar systems (−16.8 ≤ M

V
≤ −6.0), using time-series observations of RR Lyrae stars taken as part of the Hubble Space Telescope Treasury Survey of M31 Satellites. From >700 orbits of new/archival Advanced Camera for Surveys imaging, we identify >4700 RR Lyrae stars and determine their periods and mean magnitudes to a typical precision of 0.01 day and 0.04 mag. Based on period–Wesenheit–metallicity relationships consistent with the Gaia eDR3 distance scale, we uniformly measure heliocentric and M31-centric distances to a typical precision of ∼20 kpc (3%) and ∼10 kpc (8%), respectively. We revise the 3D structure of the M31 galactic ecosystem and: (i) confirm a highly anisotropic spatial distribution such that ∼80% of M31's satellites reside on the near side of M31; this feature is not easily explained by observational effects; (ii) affirm the thin (rms 7–23 kpc) planar “arc” of satellites that comprises roughly half (15) of the galaxies within 300 kpc from M31; (iii) reassess the physical proximity of notable associations such as the NGC 147/185 pair and M33/AND xxii; and (iv) illustrate challenges in tip-of-the-red-giant branch distances for galaxies with M

V
> − 9.5, which can be biased by up to 35%. We emphasize the importance of RR Lyrae for accurate distances to faint galaxies that should be discovered by upcoming facilities (e.g., Rubin Observatory). We provide updated luminosities and sizes for our sample. Our distances will serve as the basis for future investigation of the star formation and orbital histories of the entire known M31 satellite system.
On the Nature of Rotation in the Praesepe Cluster

Published: October 2022

Although a large number of Galactic open clusters (OCs) have been identified, the internal kinematic properties (e.g., rotation) of almost all the known OCs are still far from clear. With the high-precision astrometric data of Gaia EDR3, we have developed a methodology to unveil the rotational properties of the Praesepe cluster. Statistics of the three-dimensional residual motions of the member stars reveal the presence of Praesepe’s rotation and determine its spatial rotation axis. The mean rotation velocity of the Praesepe cluster within its tidal radius is estimated to be 0.2 ± 0.05 km s−1, and the corresponding rotation axis is tilted in relation to the Galactic plane with an angle of 41° ± 12°. We also analyzed the rms rotational velocity of the member stars around the rotation axis, and found that the rotation of the member stars within the tidal radius of Praesepe probably follows Newton’s classical theorems.
Entre alteridades e precariedades: breves apontamentos sobre gênero, performatividade e poder a partir da diferença
Authors: Matheus Neto Romão , Ribeiro Regiane Regina
Published: October 2022

Este texto objetiva compreender brevemente, por meio do sentido de alteridade e diferença, as definições teóricas de gênero, performatividade e poder. Para tanto, é proposta uma revisão de literatura acerca dos conceitos em Lévinas (1999), Hall (2016), Pinchesvki (2005; 2016), Butler (2009; 2011; 2018), Louro (2016) e Foucault (2017). Considera-se que a alteridade não só é a diferença imprescindível entre um ser e o Outro, mas principalmente, um processo intrínseco à comunicação e aos encadeamentos simbólicos e discursivos que condicionam certas realidades e entendimentos culturais, políticos e econômicos. Tais negociações pressupõem embates, de modo a potencializarem a precarização de corpos e identidades consideradas ininteligíveis e opostas àquelas consolidadas pelas normas.  Como práticas citacionais, o gênero e sexualidade constituem-se como algumas das importantes ferramentas para produzir vulnerabilidades e, ao mesmo tempo, para entender as diferenças de modo responsável.
First record of Theloderma khoii Ninh, Nguyen, Nguyen, Hoang, Siliyavong, Nguyen, Le, Le & Ziegler, 2022 from China, with confirmation of Rhacophorus orlovi Ziegler & Köhler, 2001 in China (Anura, Rhacophoridae)

Published: October 2022

We report the first country record of Theloderma khoii Ninh, Nguyen, Nguyen, Hoang, Siliyavong, Nguyen, Le, Le & Ziegler, 2022 from China based on a specimen collected from Wenshan Prefecture, southeastern Yunnan, China. Morphologically, the specimen from Wenshan Prefecture agrees well with the type specimens of T. khoii from Vietnam except for having a smaller body size, and phylogenetically clustered with the type specimens of T. khoii from Vietnam. In addition, we confirm the distribution of Rhacophorus orlovi Ziegler & Köhler, 2001 in China based on three specimens collected from Honghe Prefecture, southern Yunnan, China. Morphologically, the specimens from Honghe Prefecture agree well with the type specimens of R. orlovi from Vietnam except for having a slightly larger body size in adult females, and phylogenetically clustered with the specimens of R. orlovi from Vietnam (including the type locality of R. orlovi).
Épistémologie du concept d’hétérosis
Authors: Brault Nicolas
Published: October 2022

Cet article vise à étudier d’un point de vue historique et épistémologique le concept d’hétérosis. Plus précisément, il s’agit d’adopter une approche internaliste de ce concept et de cette discipline, et notamment de la resituer dans l’histoire de la génétique, à laquelle ils sont étroitement liés. En effet, la question de l’amélioration des plantes a jusqu’ici été abordée essentiellement selon une approche externaliste, qui met l’accent sur ses dimensions politiques et économiques. Si cette approche est nécessaire, elle nous parait insuffisante, et les critiques émises contre la pertinence épistémologique du concept d’hétérosis et la réalité du phénomène qu’il désigne nous semblent en grande partie injustifiées.
Les relations civilo-militaires, révélatrices du maintien des autoritarismes au Maghreb depuis 2011
Authors: Delamare Thibault
Published: October 2022

Entre 2011 et 2021, l’Algérie, le Maroc et la Tunisie ont vécu des transformations politiques suite à des mobilisations populaires massives, mais aussi la montée du terrorisme et la résurgence de la rivalité algéro-marocaine. Au cœur de ces transformations, les relations entre les institutions politiques, les armées et les forces de sécurité ont à la fois participé au déroulement des événements et évolué sous leur pression. À travers l’étude des relations civilo-militaires, cet article explique les raisons pour lesquelles ces régimes politiques ont conservé ou retrouvé leur identité propre : oligarchie politico-militaire, monarchie pluraliste et présidentialisme nationaliste-conservateur autoritaire. Ils continuent donc de s’inscrire dans un « autoritarisme durable », notamment par l’action des forces armées et de sécurité intérieure, signant l’échec des différentes mobilisations populaires aspirant à la démocratisation.
Les armées et les services de sécurité et de renseignement dans le monde arabe
Authors: Levallois Agnès
Published: October 2022

Les services de sécurité et de renseignement jouent un rôle central dans les différents pays du monde arabe. Cet article propose de présenter leurs caractéristiques communes, la première d’entre elle étant la protection du régime basée sur une culture de l’impunité sans négliger bien évidemment les spécificités propres aux différentes aires géographiques et aux conditions dans lesquelles ces États sont nés. Il s’agira ensuite de proposer une typologie des services suivant leur place au sein du pouvoir. Enfin, nous nous pencherons sur leur rôle – ou non – lors des mouvements de contestation de 2011.
Teşkilat , une série sécuritaire au service de la communication politique sur les opérations militaires de la Turquie en Syrie
Authors: Poyraz Solène
Published: October 2022

Cet article vise à démontrer la place que les séries peuvent prendre dans l’arsenal de communication développé par l’État turc, notamment après la tentative de coup d’État du 15 juillet 2016. Alors que l’entreprise de recherche et consultation Konda qualifie la société turque de « société à télévision » et que les séries constituent une interface entre le domaine public et la vie privée, une série d’espionnage diffusée sur TRT1 et mettant en scène les forces armées turques en Syrie n’est pas anodine. Il s’agit de légitimer les interventions, et plus généralement la politique syrienne de la Turquie, tout en montrant la réorganisation de l’appareil sécuritaire en faveur des services de renseignement. Finalement, la série « Teşkilat » est une mise en scène sérielle du Nouveau Concept de Sécurité qui rassure et familiarise le public avec une rhétorique basée sur un récit historique, et normalise des pratiques violentes autorisées par l’état d’exception permanent instauré depuis 2016.
The Egyptian army in the political and economic fields since 2013: a neo-military society
Authors: Tonsy Sara
Published: October 2022

Après l’arrivée au pouvoir en 2014 de l’actuel président égyptien Abdel Fattah al-Sisi, ancien général des forces armées, l’armée a gagné en puissance, en dominant encore plusieurs domaines, notamment l’économie, la politique et le récit national. À partir de matériaux primaires et de travail ethnographique, tels que les journaux et le discours politique des politiciens et des médias en Égypte, cet article répondra aux questions suivantes : Quels sont les changements politiques, économiques et discursifs mis en avant par Sisi depuis 2014 ? Comment cela a-t-il investi dans la construction d’une société militaire dominante ? En utilisant la description et l’analyse d’Anouar Abdel-Malek, de Gamal Abdel Nasser et de la société militaire des officiers libres, nous répondons aux questions susmentionnées tout en décrivant les processus et les procédures qui ont conduit à la domination actuelle de l’armée malgré la promesse initiale de Sisi que cela n’arriverait pas. Nous soutenons que le régime de Sisi a essayé d’incorporer l’appareil militaire dans tous les aspects de la vie sociale, économique et politique, tout en essayant de construire une société néo-militaire qui hégémonise ces domaines. En utilisant le discours de Sisi, et ceux de personnalités politiques et médiatiques, nous fournissons des preuves discursives pour notre argumentation et notre analyse. Le travail de terrain étant presque impossible depuis 2013 en Égypte, nous mobilisons du matériel ethnographique collecté en ligne et à travers de nombreuses visites dans le Grand Caire.
La construction d’une utopie kurde dans l’histoire. Analyse à partir d’empreintes d’archives
Authors: Le Saout Didier
Published: October 2022

Comment une utopie kurde peut se former et se maintenir dans l’histoire dans des configurations territoriales et politiques les plus variées ? A partir des documents produits par les acteurs kurdes et conservés dans les centres d’archives en France, la construction d’une utopie kurde est étudiée dans trois contextes distincts. Tout d’abord, le règlement de la Première Guerre mondiale qui organise le démembrement de l’Empire ottoman est interprété par les nationalistes kurdes comme une reconnaissance du droit de disposer d’un Etat. Ensuite, la République du Kurdistan proclamée en Iran en 1946, renouvelle l’imaginaire kurde en rendant concrets les objectifs d’autonomie et d’indépendance kurde. Enfin, durant les années soixante, les différents mémorandums rédigés par Mustafa Barzani et ses partisans en Irak révèlent les transformations induites par des contextes où la lutte armée alterne avec des négociations entre Kurdes et dirigeants irakiens. Plutôt que de considérer que l’utopie kurde aurait muté au cours du vingtième siècle d’une vision programmatique révolutionnaire en une vision réformiste à des fins d’intégration politique, il importe de mettre en avant la souplesse de la production symbolique adaptée à des contextes dans lesquels les Kurdes résistent par la force armée ou cherchent à s’affranchir de l’intégration politique au sein des Etats-nations.
Les emplois de donc au C.H.U. : étude linguistique appliquée au contexte du soin
Authors: Delsart Aline , Pironom Julie , Auriac-Slusarczyk Emmanuèle
Published: October 2022

Les fonctions de donc analysées au sein d’échanges entre patients et soignants, à partir d’un corpus de paroles authentiques recueillies en C.H.U., se ventilent en trois grandes catégories : interactionnelle, discursive et logicoïde. Sur 142 emplois étudiés, dix fonctions sont révélées parmi les treize recensées dans la littérature et sa poly-fonctionnalité s’équilibre entre fonctions prépondérantes et secondaires. Employé comme logicoïde explicatif, conséquentiel puis causal, et ce, indifféremment par les médecins et les thérapeutes, donc connaît un aspect interactionnel qui s’ajoute préférentiellement à ses emplois explicatifs. La fonction discursive est sous-représentée. En contexte de soin, l’emploi de donc contraste tendanciellement les rôles du soignant (médecin vs thérapeute) : le médecin emploie donc en fréquence standard quand le thérapeute réduit ses emplois au tiers.
Les emprunts verbaux du français à l’anglais : une analyse sémantique
Authors: Zayed Ahmad
Published: October 2022

Ce travail est consacré à la sémantique des anglicismes verbaux du français. Le sens de verbes français créés à partir d’un lexème anglais, comme cheater , liker , zoomer , est comparé au sens des verbes d’origine dans la langue source ( cheat , like , zoom ) et à celui des éventuels concurrents dans la langue cible lors de l’adoption du néologisme ( tricher , aimer ). L’analyse met en avant plusieurs mécanismes importants dans la compréhension des aspects sémantiques de l’emprunt en général et des emprunts verbaux en particulier, comme la réduction de la polysémie, la spécialisation sémantique, les extensions métaphoriques ou métonymiques et les changements de structure valencielle. Lorsqu’un terme concurrent existe dans la langue cible au moment de l’emprunt ( cheater vs tricher ), la question de l’utilité du néologisme verbal se pose. La spécificité sémantique paraît jouer un rôle crucial dans l’adoption du nouveau verbe, tout comme le marquage pragmatique.
Does size matter in group decision making? Simulation experiments with LNG professionals bidding in auction markets
Authors: Otamendi F. Javier , Muñoz Félix-Fernando
Published: October 2022

Purpose: An important issue in decision-making processes is whether groups decide better than individuals. This paper compares the bidding behavior of groups of professionals while playing a business game that simulates, in a controlled environment, the sequential unit capacity auctions in the Spanish LNG market.Design/methodology/approach: First, we randomly grouped professionals in groups of different size—SOLOs, DUOs, and TRIOs—and played the game in-situ under both First and Second price unit capacity auctions, with SOLOs outperforming groups. Second, we ran non-parametric simulations mixing professionals in groups of different size, in which bids were coupled with those registered during the in-situ sessions. Third, we ran non-parametric simulations in which the players were either ‘rational machines’ that bid according to Nash equilibrium or groups of ‘professionals’ of different size.Findings: The size of the decision group does matter. After the in-situ and the bootstrapped simulated games, the main result is that size does matter, and groups are not necessarily superior to individuals bidding alone. SOLO players bid closer to MACHINEs and lower than DUOs or TRIOs, while obtaining about the same number of units and higher payoffs than groups. Additionally, the ‘degree of rationality’ of the participants does also matter.Research limitations/implications: Even after applying the hybrid simulation methodology to increase sample size and allow for additional experimental settings, some of the scenarios are fictitious. Modification of the business game to allow for an even more realistic game could be implemented.Practical implications: After the hybrid simulation approach, the main implication of the paper is that to increase efficiency in resource allocation professionals should bid individually while using the theoretical knowledge of rational machines.Originality/value: To our knowledge, this is the first time that this double-experiment simulation methodology is used to analyze bidding behavior in auctions.
Indización automática de artículos científicos sobre Biblioteconomía y Documentación con SISA, KEA y MAUI
Authors: Gil-Leiva Isidoro , Díaz Ortuño Pedro , Fernandes Corrêa Renato
Published: October 2022

Este artículo evalúa los sistemas de indización automática SISA (Automatic Indexing System), KEA (Keyphrase Extraction Algorithm) y MAUI (Multi-Purpose Automatic Topic Indexing) para averiguar cómo funcionan en relación con la indización realzada por especialistas. El algoritmo de SISA se basa en reglas sobre la posición de los términos en los diferentes componentes estructurales del documento, mientras que los algoritmos de KEA y MAUI se basan en el aprendizaje automático y las frecuencia estadística de los términos. Para la evaluación se utilizó una colección documental de 230 artículos científicos de la Revista Española de Documentación Científica, publicada por el Consejo Superior de Investigaciones Científicas (CSIC), de los cuales 30 se utilizaron para tareas formativas y no formaban parte del conjunto de pruebas de evaluación. Los artículos fueron escritos en español e indizados por indizadores humanos utilizando un vocabulario controlado en la base de datos InDICES, también perteneciente al CSIC. La indización humana de estos documentos constituye la referencia contra la cual se evalúa el resultado de los sistemas de indización automáticos, comparando conjuntos de términos usando métricas de evaluación de precisión, recuperación, medida F y consistencia. Los resultados muestran que el sistema SISA funciona mejor, seguido de KEA y MAUI.
Corporate Social Responsibility vs. Corporate Sustainability
Authors: Falcó Javier Martínez , Marco-Lajara Bartolomé , Zaragoza-Saez Patrocinio
Published: October 2022

The research is of great interest since it allows us to know the points of convergence and divergence between two of the concepts most used today to refer to the company's commitment to society and the environment in which it operates: corporate social responsibility (CSR) and corporate sustainability (CS). Through the narrative review conducted, the research shows that both concepts are converging to refer to the commitment of companies to economic, social, and environmental well-being. However, CS researchers consider that the three dimensions are interconnected, while CSR researchers do not seem to recognize this link. Furthermore, CSR is considered to have emerged to address social issues, while CS focused on environmental issues, given that CSR has its origins in the critique of neoclassical economic theory and CS in the environmental impact of organizations.
Corporate Social Responsibility
Authors: Falcó Javier Martínez , Marco-Lajara Bartolomé , Zaragoza-Sáez Patrocinio
Published: October 2022

Corporate social responsibility (CSR) refers to a business approach that takes into account economic, environmental, and social issues in a balanced, holistic, and long-term manner for the benefit of current and future stakeholders. However, when did the term emerge? How has it evolved since its inception? Under what theoretical perspectives has it been approached? Through a narrative review of the literature, the research addresses these research questions to bring clarity to the field of study. The results of the research show that the term emerged in the 1950s, having evolved to include the economic, social, and environmental dimensions and that there are five motivations that drive its implementation: (1) alignment of interests between agents and principal, (2) satisfaction of stakeholder demands, (3) compliance with the institutional context, (4) obtaining a competitive advantage, and (5) maintaining congruence between the objectives of society and the objectives of the organization.
A Philosophical Reflection of SDG 4 and Our Education Policy
Authors: Chowdhury Jahid Siraz , Roy Parimal Kumar
Published: October 2022

No creed has called for education for peace. Instead of revealing the world of injustices, such an assertion emerged since the 1970s by Paulo Freire, Frantz Fanon from French, Syed Hussein Alatas from Malaysia, Vine Deloria from the American Indians. Later, Gayatri Spivak, Walter Mignolo, Eve Tuck, and Yung have pointed out the system's problem. This chapter demonstrates an unorthodox, non-linear discussion with UNESCO's (in effect, the SDG 4) educational program references. The inspiration came from different masterpieces—Spivak's Righting Wrong, Vine Deloria's Indigenous Metaphysics, Frantz Fanon's Black Skin White Mask, Darryl Macer's Bioethics for Love. In terms of gnoseology, the authors followed Sadia Gaon's phrase—a polymath said in 872 AD: ‘observe the unobserved' in the new normalcy—a part of practical philosophy—and the analytical or conceptual domain.

Published: October 2022

The main alloying elements have a decisive influence on the type and quantity of the second phase of the Al-Zn-Mg-Cu alloy, and even on the dissolution of the second phase during solution treatment. The effect of Zn/Mg ratio on second phase dissolution during solution treatment of Al-Zn-Mg-Cu alloys was investigated by means of differential scanning calorimetry (DSC), scanning electron microscope (SEM) and electrical conductivity testing. The results showed that Mg (Zn,Cu,Al)2 phase and Fe-rich phase existed in the as-deformed alloys. In addition, a small amount of Al2CuMg phase was found in the low and medium Zn/Mg ratio alloy. The number of Mg (Zn,Cu,Al)2 phases as the major second phase in the alloys was inversely proportional to the Zn/Mg ratio. Mg (Zn,Cu,Al)2 phase essentially dissolved into the matrix after solution treatment at 465°C/2h. Increasing the solution temperature and time were both beneficial to the dissolution of the Al2CuMg phase. With the increase of the solution temperature from 465°C to 475°C, the conductivity of the alloy showed a decreasing trend initially and then increased. As the solution time increased at 470°C, the electrical conductivity of the low-Zn/Mg ratio alloy decreased and then increased due to the more secondary phase. After the second phase was fully dissolved in the alloy, the electrical conductivity gradually increased with the increase of the solution time.

Homogenization treatment is usually indispensable to obtain a good microstructure pattern and brilliant final performance of Al-Cu-Li alloys. In the present study, the effect of different Mg contents on the microstructure of Al-Cu-Li alloys during homogenization was investigated utilizing optical microscopy (OM), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and differential scanning calorimetry (DSC) analysis. The results indicated that the higher Mg content changed the type of grain boundary phase in the as-cast alloy. The eutectic phases in the low Mg alloy were dominated by Cu-rich phases while the high Mg alloy also had many Ag-containing Al2CuMg phases. The difference in Mg contents did not affect the grain morphology, while the high Mg content in the Cu-rich phase caused a decrease in its melting point. Suitable homogenization treatments for the low and high Mg alloys are 520 °C/12 h and 495 °C/24h + 505 °C/48 h, respectively. This provides a reference for studies related to the effect of composition evolution on the dissolution of the second phase during the homogenization treatment.

The aim of this study was to characterize and evaluate the performance of two wood species, pine (Pinus sylvestris L.) and spruce (Picea abies Karst.) used for wooden furniture in outdoor coated with a water based ecological paint and subjected to artificial weathering. Another task of this research was to investigate the potential of the application of paint using dipping method in alternative to traditional brush or spraying coating application methods, since, if wood samples are grouped in stacks, the processing time can be reduced, compared to samples painted singularly. From the analysis of the dipping parameters, such as time and paint concentrations, more practical and specific knowledge was obtained regarding this painting method.From the characterization of the painted samples and from the measurements of color changes during artificial weathering it was observed that coated wood surfaces have similar optical properties also in case of different dipping times, although the type of wood could affect the performance of final product during artificial weathering test as in case of spruce wood samples, specifically those prepared with the shortest dipping time: for these samples a lower resistance to weathering and higher color changes were observed.

Necessity for reduction of greenhouse gases emissions, the growing demand for improvement of biorefinery technologies and the development of new biorefining concepts, oblige us as a society, mainly scientists, to develop novel biorefinery approaches. The aim of this research was to comprehensively characterize lignocellulosic biomass that was obtained after 2-furaldehyde production, in terms of further valorization of this resource. This research shows that birch wood chips can be used in the new biorefinery processing chain for production of 2-furaldehyde, acetic acid and subsequent cellulose pulp obtaining, using thermomechanical and alkaline peroxide mechanical pulping process. In addition, obtained lignocellulosic residue was also characterized. Unique bench-scale reactor system was used to obtain a lignocellulosic material without pentoses and with maximum preservation of cellulose fiber for further use. Studies on the deacetylation and dehydration of birch wood hemicelluloses of pentose monosaccharides to 2-furaldehyde and acetic acid using orthophosphoric acid as a catalyst were carried out. Results showed that depending on the used pretreatment conditions the 2-furaldehyde yield was from 0.04 to 10.84 % o.d.m., the acetic acid yield was from 0.51 to 6.50 % o.d.m. and the lignocellulose residue yield was from 68.13 to 98.07 % o.d.m. with minimal content of admixtures. In addition, experimentally the optimal 2-furaldehyde production conditions regarding to purity and usability of cellulose in leftover of lignocellulosic material were developed. Best results in terms of both 2-furaldehyde yield and purity of residual lignocellulose were obtained in experiment where catalyst concentration was 70%, catalyst amount 4 wt.%, reaction temperature 175 °C and treatment time 60 min. By performing alkaline peroxide mechanical pulping of the relevant LC residue, it was possible to obtain pulp with tensile index comparable to standard printing paper, indicating that it is possible to perform stepwise 2-furaldehyde production with subsequent pulping to obtain various value added products.

Plastic waste is an ever-growing concern, causing harm to many ecological and human health aspects, one of the major contributors to this problem being packaging. Mycelium composites (MC) are ecologically safe materials, well suited for the short-life usage as packaging materials. In our study we made MC using fine and coarse granulometry hemp shives applying them in 3 substrate variants – with added bran, with added bran and birch bark, and as the sole substrate. We assessed material's water absorption and mechanical properties, chemical decomposition, biodegradability, mold resistance and fungal biomass. Granulometric effect was observed only when using shives as the sole substrate, where larger particle size gave poorer results. Bran did not significantly improve mechanical properties or water uptake. Bark reduced water uptake by ~200 %, but lowered mechanical properties, and provided no benefits to mold resistance which was low for all specimens. Overall, hemp MC showed complete biodegradability after 12 weeks, mechanical properties up to 0,235 MPa, compatible with expanded polystyrene, but very high water uptake of up to 1000 %. Future studies are needed to reduce water absorption and improve mold resistance, as well as invent consensus methodology for better cross-study comparison.
Multi-target trajectory tracking in multi-frame video images of basketball sports based on deep learning
Authors: Gong Yong , Srivastava Gautam
Published: October 2022

INTRODUCTION: There is occlusion interference in the multi-target visual tracking process of basketball video images, which leads to poor accuracy of multi-target trajectory tracking. This paper studies the multi-target trajectory tracking method in multi-frame video images of basketball sports based on deep learning.
OBJECTIVES: Aiming at the problem of target occlusion in the tracking process and the problem of trajectory tracking anomaly caused by target occlusion, a modified algorithm is proposed.
METHODS:  The method is divided into two parts: detection and tracking. In the detection part, the YOLOv3 algorithm in deep learning technology is used to detect each target in the video, and the original YOLOv3 backbone network Darknet-53 is replaced by the lightweight backbone network MobileNetV2 to extract the target features.
RESULTS: Based on the target detection results, the Kalman filter is used to predict the next position and bounding box size of the target to obtain the target trajectory prediction results according to the current target position, then a hierarchical data association algorithm is designed, and multi-target tracking of the same category is completed based on the target appearance feature similarity and feature similarity.
CONCLUSION: The experimental results show that the method can accurately detect the targets in multi-frame video images in basketball sports and obtain high-precision target trajectory tracking results.

Published: October 2022

We improve to nearly optimal the known asymptotic and explicit bounds for the number of
$\mathbb {F}_q$
-rational points on a geometrically irreducible hypersurface over a (large) finite field. The proof involves a Bertini-type probabilistic combinatorial technique. Namely, we slice the given hypersurface with a random plane.
Determinantal probability measures on Grassmannians
Authors: Kassel Adrien , Lévy Thierry
Published: October 2022

We introduce and study a class of determinantal probability measures generalising the class of discrete determinantal point processes. These measures live on the Grassmannian of a real, complex, or quaternionic inner product space that is split into pairwise orthogonal finite-dimensional subspaces. They are determined by a positive self-adjoint contraction of the inner product space, in a way that is equivariant under the action of the group of isometries that preserve the splitting.
Configuration polynomials under contact equivalence

Published: October 2022

Configuration polynomials generalize the classical Kirchhoff polynomial defined by a graph. Their study sheds light on certain polynomials appearing in Feynman integrands. Contact equivalence provides a way to study the associated configuration hypersurface. In the contact equivalence class of any configuration polynomial we identify a polynomial with minimal number of variables; it is a configuration polynomial. This minimal number is bounded by

r+1\choose 2

, where

r

is the rank of the underlying matroid. We show that the number of equivalence classes is finite exactly up to rank

3

and list explicit normal forms for these classes.
Real semisimple Lie groups and balanced metrics

Published: October 2022

Given any non-compact real simple Lie group

\mathrm{G}_o

of inner type and even dimension, we prove the existence of an invariant complex structure

\mathrm{J}

and a Hermitian balanced metric on

\mathrm{G}_o

and on any compact quotient

\mathrm{M}= \Gamma\backslash\mathrm{G}_o

, with

\Gamma

a cocompact lattice. We also prove that

(\mathrm{M},\mathrm{J})

does not carry any pluriclosed metric, in contrast to the case of even dimensional compact Lie groups, which admit pluriclosed but not balanced metrics.
