"Physical culture" and "sport" are considered, first and foremost, in social terms, as a specific sphere of society's life (physical culture and health), an educational sphere (training and development of specialists in the field), and a competitive one (generating income and competitive advantages). Secondly, from an economic point of view, as a branch of the non-productive sphere, this field is a type of activity, useful from a social point of view, because it offers the population various types of services. This activity is carried out by enterprises, institutions, organizations of various forms of ownership and departmental affiliation, including individuals. According to the classification of the branches of the national economy in the Republic of Moldova, physical culture and sports are an integral part of the industry "Art, recreation and leisure activities" [3]. However, there is every reason to believe that this sphere has now formed an independent branch of the national economy, whose main product is social and cultural services, offering organized forms of exercise and sport for various purposes, as well as activities to ensure for its beneficiaries, sports facilities, organization of services, provision of sports competitions and entertainment events, professional training, scientific research, trade, rental and maintenance of sports equipment and inventory, sports insurance services, etc. Also, individuals and sports entities are the most important subjects of market relations in this field. Experts define a service as a type of activity that aims to meet the needs of others, in the process of which does not create a new material product, previously non-existent, but changes the quality of an existing product, created, i.e. services are provided (these are benefits provided not in the form of things, but in the form of socially useful activities). Thus, the provision of services itself creates the desired result. In this context, we can mention that sports services can be defined as a set of forms of activity, socio-pedagogical developed to meet the needs of different socio-demographic groups of the population towards improving fitness or to make a sports show.
THE IMPORTANCE OF THE PSYCHOMOTRICITY DEVELOPMENT IN THE LIFE CYCLE
Authors:   Secondary School „Nicolae Iorga”, Romania, Constantin Iuliana Luminiţa
Published: September 2021

In the literature, psychomotor skills are considered as a complex function, an aptitude that integrates both aspects of motor activity and manifestations of perceptual functions. The evolution of the psychomotor behaviors of each individual develops depending on his aptitude, the degree of physical and intellectual development and the educational influences to which he was subjected throughout childhood. Psychomotor skills, as a complex function that determines the regulation of human behavior, include the participation of various processes and psychic functions that ensure both the reception of information and the proper execution of motor response acts. Psychomotor skills make possible pragmatic adaptation (learning professional, manual, intellectual techniques), social adaptation (ways of interpersonal communication), aesthetic adaptation (body expression techniques), educational adaptation, through its basic components.

Published: September 2021

The article analyzes the process of institutionalization of the Olympic Movement in the Republic of Moldova, as well as the formation of the normative base of great achievement sport and its role as an instrument of foreign policy and a factor of soft power of the Moldovan State. In this regard, the author examines the continuity in the development of sports, in accordance with the two historical and political periods of the Moldovan statehood - "Soviet" and "Post-Soviet", through a comparative analysis of specific sports achievements. In this context, the author examines the main reasons for the slowdown in the development of the Olympic movement, including through the prism of content analysis the leaders of this structure, as well as the admission of systemic errors associated with insufficient funding of Moldovan sports, the lack of a legal framework for sponsoring performance sports, and the loss of the system for training highly qualified coaches.

Published: September 2021

The knowledge of the physiological processes and the mechanisms of vital activity of the organisms gives the possibility to the future specialist in the field of physical education and sports to understand the causes of the appearance of the complicated functional states of the organism characteristic for the muscular activity. This will allow them to rationally distribute physical effort and rest in both physical education and training classes, to forecast short- and longterm sports results. The results of the theoretical-praxiological analysis of the instructive-educational process within the disciplines provided by the curriculum of the faculties of physical education and sports show that in this field: - a specific evaluation system does not work, therefore it is not known what level of professional competencies and what didactic competencies the student actually has; - the desire of students to train and use their professional skills in quality sports is more declared, it is not supported by appropriate actions [6, 15, 16]. The theoretical study of the problem of training-development of professional skills identified different approaches to its classification and typology: some real results-oriented, and others with confusing orientation in this regard, neither of the two types of approaches, at least in the field of physical education, not being sufficiently argued from a systemic point of view

Numerous scientific studies report on the importance of improving the methodology of developing motor skills through martial arts, while identifying the links between these indices, which ensures an optimal level of motor training of subjects. In this paper are presented the results of the study on the existence of correlative links between the indices of motor skills development and the level of mastery of the technique of the martial arts elements. For this purpose, a test was carried out in which the military students (first year) of the "Henri Coandă" Air Force Academy from Brasov participated. The test results confirmed the existence of a reciprocal link, highlighting significant interdependencies between the indices obtained. The analysis of the correlation of the parameters of motor skills and the level of mastery of technical elements in martial arts allow us to mention that the intensity of links is significant at high and medium levels in most cases, which reflects the fact that the indices influence each other.

The current situation regarding the state of health, and here we can refer to the functional impairment of the spine of pre-pubertal age children, is superficially approached from the prevention point of view. Global or partial physical deficiencies, as well as the vicious positions of the body, could be favorably influenced by the use of physical exercises as an associated means of kinesiotherapy. Currently, the problem of somato-functional growth and development of pre-pubertal children, related to the existing postural hygiene programs, is in a deficient situation, favoring the installation of vicious postural attitudes, which cause complications in the spine such as functional physical deficiencies.

Published: September 2021

Après le coup d’envoi des chantiers de développement au Maroc, le tourisme est un secteur qui a été mis en exergue avec une certaine solennité. Il a été considéré comme étant l’un des pilotis des ressources économiques et la machine motrice du développement. En effet, le secteur a renouvelé ses stratégies managériales en définissant des objectifs très ambitieux qui permettent la consolidation et la mise en relief de différents types de tourisme, notamment le durable, le rural et le tourisme de nature.
Ces nouveaux chantiers préconisés ont été pris en considération après les nouvelles envergures qu’a connues le monde, telles que la valorisation du patrimoine culturel, la protection du patrimoine naturel et de l’environnement, les nouvelles destinations rurales… (etc). De l’idée de faire fondre les barrières entre ces différentes considérations, de vouloir participer à la gestion touristique de notre pays et d’attirer l’attention vers les lieux naturels à attraits touristiques ; nous nous somme emportés par l’idée de loger le tout sous la même toiture et c’est là où nous sommes parvenus aux Paiements pour Services Environnementaux (PSE). Notre projet est la définition d’un fond de PSE permettant la préservation, la sauvegarde et la valorisation des sites naturels à caractère touristique, il verra jour à Tafraout/Ameln. Une région appartenant à la Réserve de Biosphère de l’Arganeraie (RBA), qui offre des ressources d’exception au niveau géographique et socioculturel ainsi que des potentialités naturelles, lui permettant de devenir une destination de tourisme durable et d’écotourisme. L’instauration d’un concept PSE dans cette région prendra la forme d’un financement de système de préservation, de sauvegarde et de promotion, qui aura pour buts de: consolider les efforts de gestion et de management déployés par les acteurs dans le sens de l’environnement, de la nature et du tourisme; d’allouer le financement nécessaire aux frais de gestion et de combler les insuffisances de financement de l’état au profit de la valorisation, la structuration et la préservation des sites naturels touristiques. Toutefois, ce projet fait remonter une panoplie d’interrogations ; Quel sera le montant de ce financement ? Pour quelle démarche de sauvegarde ? Qui en sera le bénéficiaire ? Est-ce que cette nouvelle méthode managériale sera efficiente ? Tant d’autres énigmes ont été résolues dans notre travail de recherche, cet article fera le tour des enquêtes, des études de terrain et des collaborations avec les parties prenantes qui nous ont permises de confectionner notre modèle PSE.

The paper presents studying sedative activity of the combined tincture of motherwort and St. John's wort. The combined tincture of motherwort and St. John's wort was obtained by percolation method in a ratio 1:10. Standardization of the obtained tincture was carried out with quality indicators: description, content of active ingredients and ethanol, relative density, dry residue. According to all quality indicators, the tincture obtained met the requirements of the State Pharmacopoeia of the Republic of Belarus. Specific sedative activity of the combined tincture of motherwort and St. John's wort was assessed by barbiturates hypnotic effect prolongation (sodium thiopental), by the rate of falling asleep in animals and by animals staying in lateral position in relation to the control group to which sodium thiopental was injected. In the studies carried out it was found that injection of the combined tincture of motherwort and St. John's wort at a dose of 0,1 ml / kg increases sleep by 125,63% and also accelerates the process of falling asleep by 327,75% compared with the separate injection of motherwort and St. John's wort tincture at doses of 0,1 ml/kg. It was shown that the injection of the combined tincture of motherwort and St. John's wort at a dose of 0,1 ml/kg exhibits a potentiated effect and enhances the hypnotic effect of sodium thiopental administered at a dose of 10 mg/kg.
Optimality Theoretical Approach in Resolving Vocalic Hiatus in Tiv Language
Authors: I.A. Francis , U. Elizabeth
Published: September 2021

This paper investigates vocalic hiatus resolution strategies in Tiv language. Hiatus is a phonological phenomenon whereby two vowel sounds occur in adjacent syllables with no intervening consonant. It is a dispreferred configuration in many languages but when it inevitably occurs, it is resolved through some of these strategies: epenthesis, vowel assimilation, vowel elision, secondary articulation, vowel coalescence, glide formation and diphthongization. Though there are other hiatus resolution strategies in Tiv, for want of time and space, this paper examines the most common ones: vowel assimilation and vowel elision, as hiatus resolution/repair strategies in Tiv, through the lenses of the Optimality Theory. It adopts a descriptive and analytical research design. The intuitive phonological ability of the researcher and oral interview through purposive sampling were used for eliciting data. Data were presented and analysed in tables. The study establishes the occurrence of vowel hiatus in Tiv. It demonstrates that vocalic hiatus is dispreferred in Tiv as it is in many other languages of the world. The study has shown that Tiv utilises inter-alia vowel assimilation and vowel elision to resolve vowel hiatus. The resolution is meant to ease articulation of Tiv words. Well-formedness of vowel configurations in Tiv was found to be constraint based in which case optimality of a candidate that undergoes repairs through either vowel assimilation or elision is determined by the ranking of the universal constraints that interact in the selection of candidates.

O artigo apresenta a noção de hexis corporal na obra de Bourdieu e um levantamento de sua utilização em teses e dissertações brasileiras. A noção de hexis corporal compreende as disposições corporais do habitus, trata-se da compreensão do corpo enquanto um signum social. A busca realizada no Catálogo de Teses e Dissertações da CAPES revelou a utilização da noção de hexis corporal em pesquisas empíricas com diversos grupos sociais, tais como: professores, militares, camponeses, esportistas, dentre outros. Nessas pesquisas, a noção é associada às análises que remetem a outros aspectos da obra de Bourdieu: a distinção social, o senso prático, as disputas simbólicas, as matrizes de classificações sociais e ao corpo socialmente tratado.
medo dos muçulmanos
Authors: Souza Felipe Freitas de
Published: September 2021

O espaço social contemporâneo nas grandes cidades ocidentais recebe muçulmanos que estão em situação de refúgio e migração. Junto às transformações globais acarretadas por diferentes dinâmicas, a islamofobia surge enquanto discurso e prática sobre essas populações. Neste artigo, objetiva-se discutir as representações sobre os muçulmanos em situação de refúgio tomando-se como representativos quatro eventos recentes na década de 2010 envolvendo a direita e a extrema direita: o atentado de Anders Breivik na Noruega; a manifestação do grupo Direita São Paulo na capital do estado; a manifestação do grupo Geração de Mártires no Rio de Janeiro; e o atentado terrorista contra uma mesquita na cidade de Christchurch, na Nova Zelândia. Indicamos a internet enquanto meio de projeção dos discursos anti- Islam e anti-refugiados. Concluímos que a islamofobia, enquanto mentalidade, deve ser problematizada, uma vez que a xenofobia acerca dos muçulmanos é socialmente estimulada mais do que resultante exclusivamente de processos psicológicos individuais.

When the economy is in such bad shape, any of us who has a job is fortunate. Human resource managers and practitioners are concerned with whether employees are contributing to the organization’s Strategy, goals, and priorities or not, as well as how to proceed with the recruiting and selection process, employee engagement, and training and development programs, as a consequence of the pandemic of Covid-19. Organizations all over the world are in a difficult situation; for the first time in history, the value of a barrel of oil dropped to less than zero on April 20, 2020; the only explanation for this is the ongoing global lockdown. The actual workplace has been transformed into a virtual workplace, and HR managers are now pondering how to effectively involve workers. The aim of this paper was to clarify how employee engagement affects organizational efficiency within Covid-19 pandemic and shed the light on all the factors and provide a set of managerial implications to the professionals.
The regulatory compliance system: Impact of AML/CFT implementation on the financial performance of Lebanese banks
Authors: Chaabo Naser
Published: September 2021

The purpose of this paper is to provide a better understanding of how the financing of the compliance obligations which are related to “AML / CFT” (Anti-Money Laundering and Combating the Financing of Terrorism) does affect the financial performance of banks in Lebanon. The main question is: Does the compliance system play a positive impact on the risk management in Lebanese banking sector? Based on a sample of 66 respondents from BLOM Bank employees, the empirical results showed that the employment of a compliance regulatory system has increased bank’s costs. However, its implementation is not an option since it guarantees the compliance with the local, regional and international policies. Besides, the study revealed that there are numerous benefits associated with these costs that help banks to increase their awareness towards policies and regulations. These benefits are related to the high level of staff training, the closer due-diligence leveling, and the deeper contribution in combating tax evasion by implementing the CRS (Common Reporting Standards) standard in banks systems, which guarantee that information on financial accounts will be automatically exchanged between governments from a worldwide point of view
Política económica y derechos humanos
Authors: Moya Francisca , Salgado Constanza
Published: September 2021

La noción de constitución económica es generalmente usada para referirnos al marco social y político que configura la economía en un país. Este marco se puede encontrar consagrado en normas establecidas en la constitución o bien por su interpretación doctrinaria o jurisprudencial. El presente trabajo busca analizar la Constitución de 1980 para identificar y entender su contenido económico, y cómo éste ha configurado la política económica chilena en las últimas cuatro décadas. Con este objetivo, este trabajo está dividido en tres secciones, además de esta introducción. En la sección b nos referimos al concepto de constitución económica buscando aclarar los distintos usos que éste ha recibido. Sobre esta base, revisamos los elementos más característicos de la noción de constitución económica en el derecho comparado y proponemos una clasificación en base a estos elementos. Luego, en la sección c, describimos los elementos económicos que pueden encontrarse en el texto constitucional de 1980 y explicamos cómo la doctrina hegemónica fue mucho más allá del texto constitucional generando una cultura interpretativa que veía en ella una constitución neoliberal. Esta cultura interpretativa a su vez contribuyó a proteger el modelo económico impuesto por la dictadura durante la década de los 80’. Finalmente, en la sección d, proponemos para la nueva Constitución chilena una constitución económica abierta, que, a diferencia de la Constitución de 1980, permita a la deliberación pública democrática elegir la política económica a aplicar.
La prohibición de regresividad en materia de derechos sociales: apuntes introductorios
Authors: Courtis Christian
Published: September 2021

El presente trabajo introduce el tema de la prohibición de regresividad y los principales problemas de interpretación que ella plantea.118 La cuestión resulta relevante para la reforma constitucional chilena en la medida en que la plena incorporación de derechos económicos, sociales y culturales a la nueva constitución debe ser cualificada por el principio de progresividad, en línea con el PIDESC y con otras constituciones que emplean un lenguaje similar. En tal sentido, la prohibición de regresividad constituye una garantía contra la afectación de los niveles ya otorgados de estos derechos. En este artículo me dedicaré a la identificación de los parámetros en materia de prohibición de regresividad desarrollados a partir del Pacto Internacional de Derechos Económicos, Sociales y Culturales, del que Chile es parte, y ofreceré algunos criterios para su interpretación y aplicación.
¿Tiene límites la Convención Constitucional?
Authors: Astroza Suárez Paulina , Maturana Toledo Carlos
Published: September 2021

La instauración de un nuevo orden constitucional es siempre un tema crítico que produce un fuerte impacto generándose un período de incertidumbre inicial y un proceso posterior de ajuste al nuevo sistema, no exento de dificultades y dudas, de avances y retrocesos. Esta afirmación cobra aún más relevancia en nuestros días en que la Constitución ha dejado de ser un simple código político, una carta de navegación de escasa significación jurídica y se ha transformado en una verdadera norma jurídica, con alto valor normativo, pese a su frecuentemente menor densidad prescriptiva. Los desarrollos legislativos, las prácticas políticas y las decisiones de los tribunales han ido dotándola de una vigencia real y efectiva, a veces hasta insospechada para sus redactores. Además, la opinión pública y la ciudadanía están cada día más involucrados en la res publica, manifestándose y presionando por cambios en los Estados que incluyen, en muchos casos, su texto constitucional. Este trabajo pretende concentrarse en los posibles límites del poder constituyente originario con un análisis en particular del artículo 135 de la Ley N° 21.200 de reforma constitucional. Abordaremos el concepto de poder constituyente y derivado, la dimensión interna e internacional y sus consecuencias, para concluir respondiendo la pregunta de inicio de nuestro análisis.

Обзор научной литературы по теории интерференции рентгеновских лучей
показывает, что вопросам изучения тонких имплантированных слоев рентгенодифракционными методами посвящено много работ. Все эти работы имеют некоторые общие
характерные черты. В частности, все рентгенотопографические исследования проводились с образцами, которые облучались энергиями выше 1 МэВ.
При облучении ионами с низкими энергиями, в особенности в малых дозах,
необходимо пользоваться рентгеноинтерферометрическими методами, чувствительность и разрешение которых несравнимо велики. В настоящей работе приведены
результаты теоретических и экспериментальных рентгеноинтерферометрических
исследований несовершенств кристаллов, возникающих в результате ионной
имплантации малыми дозами и низкими энергиями.
Результаты исследований представлены с помощью рентгенодифракционных
муаровых картин полей деформаций, возникающих в одной из работающих частей
зеркального блока трехкристального рентгеновского кремниевого интерферометра,
подвергнутого ионной имплантации, в зависимости от дозы облучения. Исследовано
также перераспределение напряжений, возникающих в этом участке блока интерферометра при его бомбардировке. Полученные результаты дают основу для решения
обратной задачи, а именно - задачи восстановления полей механических напряжений
в кристаллических блоках интерферометра путем расшифровки муаровых картин, так
как изменение муаровых картин будет заключать в себе информацию о механических
напряжениях. Таким образом, метод рентгеноинтерферометрического муара дает возможность прямого экспериментального изучения полей механических напряжений,
созданных структурными дефектами кристаллической решетки. Выведено условие

In-silico discovery of antidiabetic drug potential of Balanites aegyptiaca leaf’s phenolic compounds
Authors: Mhya Daniel , Nuhu Asmau , Mankilik Mary
Published: September 2021

Balanites aegyptiaca leaf is very eﬀective in managing diabetes and rich in phenolic compounds. However, the modes of action of the phytochemicals are mainly unknown. Thus, the present in silico drug discovery study on some phenolic compounds was designed to evaluate potential mechanisms of action of the antihyperglycemic phytochemicals of B. aegyptiaca leaf extract. The study deployed in silico drug-like studying techniques such as; predicted activity spectra of substances (PASS), molecular docking, prediction of adsorption, distribution, metabolism, excretion, and toxicity (ADMET), Lipinski’s rule of 5 (PLOP). The study reveals six compounds with good drug-like properties: cLogp, hydrogen bond donor/acceptor (<5/ < 10), and molar refractivity. In addition, ADMET and drug properties like kinase inhibitors, ion channel modulators, and nuclear receptors were positive for the compounds. Each phenolic compound showed one or more antidiabetic activities like insulin promoter, insulin sensitizer and inhibitors of α-amylase and α-glucosidase. Docking result predicted that the phenolic compounds inhibited either α-amylase or α-glucosidase while one of the compounds; 2-methoxy-4-(1-propenyl)-phenol inhibited both α-amylase and α-glucosidase with binding energies of -4.4 and -4.2 kcal/mol against -3.8 and -4.8 kcal/mol by Acarbose. The study revealed that phenolic compounds from B. aegyptiaca leaf possessed drug-like properties, including the ability to interact with α-amylase and α-glucosidase, a vital target protein in the management of diabetes mellitus. The data from the in silico study is a step toward the pharmaceutical discovery of the antidiabetic drug potential of B. aegyptiaca leaf.
Reared to become wild-like: addressing behavioral and cognitive deficits in cultured aquatic animals destined for stocking into natural environments—a critical review
Authors: Näslund Joacim
Published: September 2021

Hatchery-reared aquatic animals tend to perform worse in natural environments than wild conspecifics. This was pointed out over a century ago and while there are many possible causes, one persistent observation is that unnatural rearing environments cause behavioral expressions unsuitable
for a life in the wild. Behavioral traits being adaptive in barren, food-rich, and predator-free hatchery tanks likely differ from those being adaptive in nature. More recently, suspicions of cognitive deficiencies due to sensory deprivation have also been raised. Over the last few decades,
substantial research has been devoted to produce more wild-like phenotypes in animals reared for stocking. This research includes life- skills training programs, where animals learn to cope with important features of the natural environment (e. g., live food and predation risk), and environmental
modifications aimed at stimulating the formation of adequate cognitive and behavioral traits (e. g., environmental enrichment and reduction of the number of individuals per tank). The main purpose of this paper is to provide a summary of the current state-of-knowledge of interventions aimed
at ameliorating cognitive and behavioral deficiencies in aquatic animals reared for stocking. Furthermore, it aims to provide a foundation to assist in the development of future questions, hypotheses, and experiments to eventually improve the postrelease performance of these animals.
Free transport for convex potentials
Authors: Dabrowski Yoann , Guionnet Alice , Shlyakhtenko Dima
Published: September 2021

We construct non-commutative analogs of transport maps among free Gibbs state satisfying a certain convexity condition. Unlike previous constructions, our approach is non-perturbative in nature and thus can be used to construct transport maps between free Gibbs states associated to potentials which are far from quadratic, i.e., states which are far from the semicircle law. An essential technical ingredient in our approach is the extension of free stochastic analysis to non-commutative spaces of functions based on the Haagerup tensor product.
Circulant association schemes on triples
Authors: Praeger Cheryl , Bhattacharya Prabir
Published: September 2021

Association Schemes and coherent configurations (and the related Bose-Mesner algebra and coherent algebras) are well known in combinatorics with many applications. In the 1990s, Mesner and Bhattacharya introduced a three-dimensional generalisation of association schemes which they called an {\em association scheme on triples} (AST) and constructed examples of several families of ASTs. Many of their examples used 2-transitive permutation groups: the non-trivial ternary relations of the ASTs were sets of ordered triples of pairwise distinct points of the underlying set left invariant by the group; and the given permutation group was a subgroup of automorphisms of the AST. In this paper, we consider ASTs that do not necessarily admit 2-transitive groups as automorphism groups but instead a transitive cyclic subgroup of the symmetric group acts as automorphisms. Such ASTs are called {\em circulant} ASTs and the corresponding ternary relations are called {\em circulant relations}. We give a complete characterisation of circulant ASTs in terms of AST-regular partitions of the underlying set. We also show that a special type of circulant, that we call a {\em thin circulant}, plays a key role in describing the structure of circulant ASTs. We outline several open questions.
Dynamics of the meromorphic families $f_\lambda=\lambda \tan^pz^q$
Authors: Chen Tao , Keen Linda
Published: September 2021

This paper continues our investigation of the dynamics of families of transcendental meromorphic functions with finitely many singular values all of which are finite.   Here we  look at a generalization of the family of polynomials $P_a(z)=z^{d-1}(z- \frac{da}{(d-1)})$, the family $f_{\lambda}=\lambda \tan^p z^q$.  These functions have a super-attractive fixed point, and, depending on $p$, one or two asymptotic values.   Although many of the dynamical properties generalize, the existence of an essential singularity and of poles of multiplicity greater than one implies that significantly different techniques are required here.   Adding transcendental methods to standard ones, we give a description of the dynamical properties; in particular we prove the Julia set of a hyperbolic map is either connected and locally connected or a Cantor set.   We also give a description of the parameter plane of the family $f_{\lambda}$.  Again there are similarities to and differences from  the parameter plane of the family $P_a$ and again  there are new techniques.   In particular, we prove there is dense set of points on the boundaries of the hyperbolic components that are accessible along curves and we characterize these  points.

Authors: Ionescu Marius , Kumjian Alex , Renault Jean N. , Sims Aidan , Williams Dana P.
Published: September 2021

We analyse extensions $\Sigma$ of groupoids G by bundles A of abelian groups. We describe a pushout construction for such extensions, and use it to describe the extension group of a given groupoid G by a given bundle A. There is a natural action of Sigma on the dual of A, yielding a corresponding transformation groupoid. The pushout of this transformation groupoid by the natural map from the fibre product of A with its dual to the Cartesian product of the dual with the circle is a twist over the transformation groupoid resulting from the action of G on the dual of A. We prove that the full C*-algebra of this twist is isomorphic to the full C*-algebra of $\Sigma$, and that this isomorphism descends to an isomorphism of reduced algebras. We give a number of examples and applications.
Trisections and link surgeries
Authors: Kirby Robion , Thompson Abigail
Published: September 2021

We examine questions about surgery on links which arise naturally from the trisection decomposition of 4-manifolds developed by Gay and Kirby \cite{G-K3}. These links lie on Heegaard surfaces in $\#^j S^1 \times S^2$ and have surgeries yielding $\#^k S^1 \times S^2$. We describe families of links which have such surgeries. One can ask whether all links with such surgeries lie in these families; the answer is almost certainly no. We nevertheless give a small piece of evidence in favor of a positive answer.
TURİZMDE JEOSEMİYOTİK: BİR META-SENTEZ ÇALIŞMASI
Authors: AVCI Ceren
Published: September 2021

ÖZ
Gösterge, başka bir şeyi temsil etmek için kullanılabilecek herhangi bir şey olarak tanımlanmaktadır. Gösterge sistemlerinin çalışmasına göstergebilim denmektedir. Jeosemiyotik ise, mekân göstergebilimi, görsel göstergebilim ve etkileşim düzeni bileşenlerinden oluşmaktadır. Mevcut çalışmada jeosemiyotik ve turizm kapsamında gerçekleştirilmiş alan araştırmalarının meta-sentezi yapılmıştır. Bu amaçla ilk olarak çeşitli veri tabanları taranarak konuyla ilgili çalışmalara ulaşılmış, ardından bu çalışmalar bir elemeye tabi tutularak toplamda 14 çalışmanın ortaya koyduğu ortak temalar belirlenmiş ve bu temalar yorumlanmıştır. Araştırma bulgularına göre, İngilizce’nin bir statü veya bir ayrıcalık göstergesi, bir dışlanma ve içerilme aracı olarak kullanılabilmekte olduğu, özellikle otantik bir deneyim amaçlandığında ise küresel göstergelerin yerini yerel göstergelere, yerel dil kullanımlarına bırakmakta olduğu ortaya çıkmıştır. Ayrıca dışlanma ve içerilmeye ilişkin göstergeler en çok turistlerin kendini ayrıcalıklı hissetmek istediği lüks veya alternatif turizm türleriyle kitle turizmi arasındaki ayrımda gerçekleşmektedir. Sonuç kısmında, sentezde ulaşılan temel noktalar özetlenmiş ve araştırmanın, takip eden araştırmalara bir yol çizmesi hedeflenmiştir.
jóvenes y los límites de la democracia. El rol de los jóvenes indígenas en el escenario político peruano
Authors: Pariona Tarqui Tania
Published: September 2021

A la gravedad de la crisis político-institucional que vive el Perú se suman la vigencia de viejos problemas y brechas sociales, culturales y económicas que provienen, a dos años de nuestro Bicentenario como República, desde nuestra propia independencia política, que se han mantenido durante nuestra etapa republicana y afectan principalmente a los indígenas peruanos. El presente ensayo pretende realizar un contraste entre las graves fracturas persistentes y, a partir de ellas y desde mi experiencia como congresista de la República, realizaré la formulación de temas estratégicos desde la perspectiva de la juventud indígena nacional.
condición tecno-ecológica. Heidegger ante los nuevos post-humanismos
Authors: Sandoval Rodrigo Y.
Published: September 2021

Muchas de las reflexiones contemporáneas sobre ecología parten del cuestionamiento de la excepcionalidad del ser humano. Se busca de esta manera el distanciamiento de todo antropocentrismo y, en consecuencia, un marco conceptual ―post-humanista‖. El rol de Martin Heidegger en la búsqueda de alternativas al humanismo es reconocido, particularmente, por su rechazo al ―antropocentrismo‖ de Sartre. Sin embargo, mientras muchos post-humanismos ven en la tecnología un factor positivo en el descentramiento de lo humano, son conocidas las críticas heideggerianas a la técnica y su comprensión de ésta como parte del mismo movimiento metafísico (y antropocéntrico) moderno. En lugar de tomar en cuenta sus textos sobre la técnica, en este artículo se explora la relación de Heidegger con los post- humanismos contemporáneos a partir de la analítica existencial del Dasein. En primer lugar, se considera la situación tecnocientífica actual, siguiendo a autores como Wiener, Haraway y Latour. En segundo lugar, se evalúa la relación entre Dasein, cíborg y animal, a partir de las lecturas heideggerianas de Hubert Dreyfus (What Computers Can’t Do) y Steven Crowell (We Have Never Been Animals).

Much of the contemporary thought about ecology begins with the questioning of the human exceptionality. By means of this, anthropocentrism is rejected and replaced by a ―post-humanist‖ framework. In this context, Martin Heidegger‘s oeuvre is credited for its search of alternatives to humanism, particularly because of its rejection of Sartre‘s ―anthropocentrism‖. However, while post- humanisms tend to behold the role of technology positively, Heidegger‘s critiques to the technique as a consequence of the same metaphysical and anthropocentric movement are widely known. Instead of considering the common Heideggerian texts about technique, in this paper I explore the relationship between Heidegger and contemporary post-humanisms from the perspective of his existential analytic. In the first place, I will briefly describe the contemporary techno-scientific context, following the insights of Wiener, Haraway and Latour. In the second place, I will consider the relationship between Dasein, cyborgs and animals, discussing the Heideggerian interpretations of Hubert Dreyfus (What Computers Can’t Do) and Steven Crowell (We Have Never Been Animals).
entumecimiento subjetivo:
Authors: Bazán Luis Enrique
Published: September 2021

El presente trabajo articula a la categoría Entumecimiento Subjetivo como una alternativa de colocación para leer las realidades sociales contemporáneas. A raíz de experiencias coyunturales de alta tensión emocional, el entumecimiento se piensa para responder y resignificar el espacio psíquico límbico con sensación de desconexión en que los sujetos se encuentran cuando el contexto ejerce lo dominante para mantener tendencias hegemónicas. La categoría sirve de dispositivo para reconocer aquello que bloquea la visualización de horizontes posibles de cambio, pero también para ver la potencialidad de desencadenar conciencias y esperanzas que respondan a las preocupaciones sociales más sentidas. Lo subjetivo, lo social, lo sistémico y lo hegemónico son elementos que se complementan y tensionan entre sí constantemente, lo cual llena de contenido a lo que se quiere articular, y permite la oportunidad de participar en la transformación con sentido de los propios contextos sociales.
This work articulates the Subjective Numbness category as a placement alternative to read contemporary social realities. As a result of conjunctural experiences of high emotional tension, numbness is thought to respond and resignify the limbic psychic space with a feeling of disconnection in which the subjects find themselves when the context exerts the dominant to maintain hegemonic tendencies. This category serves as a device to recognize what blocks the visualization of possible horizons of change, but also to see the potentiality of unleashing consciences and hopes that respond to the most felt social concerns. The subjective, social, systemic, and hegemonic are elements that constantly complement and tension each other, which fills with content what one wants to articulate, and the understanding of these tensions opens the opportunity to participate in the meaningful transformation of their own social contexts.
Deberes de caridad, deberes de justicia y la creación del otro en la tradición kantiana
Authors: Sanchez-Perez Jorge H.
Published: September 2021

Este artículo sostiene que hay problemas importantes en la tradición kantiana, en la medida en que existe una tendencia persistente a atribuir valor intrínseco basado en la existencia de capacidades cognitivamente relevantes. Además, se argumenta que después de un análisis de la obra de Kant, la exclusión de seres moralmente relevantes es una inclinación prevalente de la tradición. El trabajo de Rawls es utilizado para mostrar cómo, del racismo, el proyecto kantiano pasa al capacitismo. En la conclusión, se demuestra que incluso una versión más contemporánea y abierta de la tradición kantiana, como la defendida por Korsgaard, sigue vinculada a los mismos problemas que las formulaciones anteriores de la tradición.

In this paper, there are important problems in the Kantian tradition that are argued, insofar as there is a persistent tendency to attribute intrinsic value based on the existence of cognitively distinct capacities. Furthermore, it is argued that after an analysis of the work of Kant the exclusion of morally relevant beings is a prevalent inclination of the tradition. The work of Rawls is used to show how from racism, the project moves on to ableism. In the conclusions, is showed that even a more contemporary and open version of the Kantian tradition, such as the one defended by Korsgaard, is still bound to the same problems as the previous formulations of the tradition.

Authors: Kaur Arshpreet , Sidhu M. C. ,   Department of Botany, Panjab University, Chandigarh - 160 014, India
Published: September 2021

The present study was aimed to investigate the biologically active compounds present in the seed and leaf extracts of Millettia peguensis. Screening was done through preliminary qualitative analysis of phytochemicals and Gas Chromatography-Mass Spectroscopy (GC-MS) method. The study revealed the presence of alkaloids, carbohydrates, flavonoids, glycosides, gum and mucilage, phenolics, quinones, steroids and terpenoids in both aqueous and ethanol extracts of leaves and seeds. The GC-MS analysis of ethanol extracts of seeds and leaves have yielded 29 and 23 phytoconstituents, respectively. These observations were further validated by Fourier transform infrared spectroscopy (FT-IR) of the leaves and seeds powder. FT-IR has provided detailed information of the various functional groups associated with the compounds present in the samples. A single compound was isolated through Column Chromatography and Thin Layer Chromatography whose characterization was done through mass spectroscopy and IR spectroscopy.
