Abstract

The Lindholm rock lizard,Darevskia lindholmi, is the only member of the genusDarevskiawhose range is restricted solely to Europe, representing a local endemism found only in the Crimean Mountains. In our study, we investigated the cytochromebgene (mtDNA) of 101D. lindholmisequences from 65 Crimean localities, representing its entire range. We found thatD. lindholmiis highly genetically structured, and its range is divided into populations belonging to three mitochondrial lineages. The Lindholm rock lizard populations inhabiting the middle part of the Crimean Mountains (further referred to as the Central lineage) are sharply differentiated from the other two lineages (the Common and the Southwestern lineages), which are present in most of the species range. The genetic distance between the Central lineage and the other two taken together is 4.6%, according to our results, suggesting that the divergence occurred during the Early Pleistocene. The narrowly distributed Southwestern lineage and the widespread Common lineage, on the other hand, are differentiated by 1%. Field observations on the representatives of the main evolutionary groups show that their ecology is also different: the Central lineage is a mesophilic and cold-resistant form, while the other two closely related lineages are more xerophilic and thermophilic. Results of the potential ranges modeling and ecological niche analysis confirm that the genetic lineages occupy different niches of the Crimea. Furthermore, the area of inhabitation of the Central lineage splits the western and eastern parts of the Common lineage range, while the Southwestern lineage is restricted along the coast of the southwestern coast of the peninsula. The long-term co-existence of deeply divergent sister mitochondrial lineages in a relatively small (circa 7,000 km2) isolated mountain system serves as a mesocosm for understanding the speciation process. Our data suggest that the Central lineage warrants further taxonomic investigation.

Higher education is one of the driving forces behind the social and economic development of countries, with the ultimate aim of providing quality academic training. At present, teaching-learning models in virtual environments face a number of important challenges, particularly in the current situation caused by COVID-19. Some of these challenges will be addressed in this study. We worked with 225 third-year undergraduate students in health science degrees over two academic years during the pandemic. The objectives were: (1) to ascertain whether there were significant differences in student satisfaction with the teaching process in the first year of the pandemic (e-learning teaching) vs. the second year (b-learning teaching); (2) to determine whether there were significant differences in academic performance between the two groups. Quantitative research (using a 2x2 factorial design, ANOVA and ANCOVA) and qualitative research (using a comparative design with categorisation analysis) were carried out. The results indicate differences in some aspects of satisfaction and learning outcomes in favour of teaching in the second of the two years. Students rated the use of active methodologies and technological resources positively, although they concluded that their use required more work time. Future studies will seek to compare student satisfaction in other areas of knowledge.

La Educación Superior es uno de los motores del desarrollo social y económico de los países, teniendo como objetivo último el de facilitar una formación académica de calidad. En la actualidad, los modelos de enseñanza-aprendizaje en entornos virtuales implican retos importantes, específicamente en la actual situación por la COVID-19. Algunos de estos desafíos se abordarán en este estudio. Se trabajó con 225 estudiantes de tercero de grado en titulaciones de Ciencias de la Salud, a lo largo de dos cursos académicos impartidos durante la situación de pandemia. Los objetivos fueron: 1) comprobar si existían diferencias significativas en la satisfacción de los estudiantes con el proceso docente respecto del primer año de pandemia (se aplicó docencia e-Learning) vs. el segundo año (se aplicó docencia b-Learning); 2) comprobar si existían diferencias significativas en los resultados académicos entre ambos grupos. Se realizó una investigación cuantitativa (se utilizó un diseño factorial 2x2, ANOVA y ANCOVA) y otra cualitativa (se utilizó un diseño comparativo con análisis de categorización). Los resultados indican diferencias en algunos aspectos de la satisfacción y en los resultados de aprendizaje, a favor de la docencia en el segundo año. Los estudiantes valoraron positivamente el uso de metodologías activas y de recursos tecnológicos, si bien concluyeron que su uso exigía más tiempo de trabajo. Futuros estudios se dirigirán a contrastar la satisfacción de estudiantes en otras ramas de conocimiento.
Families’ perception of children’s academic performance during the COVID-19 lockdown

Published: October 2021

The COVID-19 pandemic forced many countries to impose a strict lockdown policy on citizens during a prolonged period of time, which led to changes in lifestyle habits. This unprecedented situation has given rise to numerous studies aimed at determining the effects of the changes brought about by this widespread lockdown. One of the important changes was the digitisation of education and, therefore, teaching, which caused a forced and abrupt immersion in distance learning. In this study, a quantitative methodology based on an ex post facto research design was used with the aim of analysing the impact of the COVID-19 lockdown on the academic performance of schoolchildren (aged 3-12 years). A total of 529 parents completed an ad hoc questionnaire on the impact of COVID-19 on their children’s education in Spain. The results produced a robust model based on structural equations that explain 39.7% of the variance in academic performance at home. The family-school relationship was the variable with the greatest explanatory weight (?=.505; p<.05). In conclusion, the benefits derived from a strong relationship between families and schools, evidenced by the creation of cooperation and communication links, facilitate the management of shared educational challenges such as on-line education in times of crises.

La situación generada por el obligado confinamiento a la sociedad por la COVID-19 ha llevado, en muchos países, a cambios en los hábitos de vida que han generado numerosos estudios para conocer los efectos de esta nueva situación social. Un importante cambio fue la digitalización del trabajo y, por ende, de la enseñanza, provocando la inmersión forzada en una educación escolar a distancia de una manera abrupta. Se realizó un estudio empleando metodología cuantitativa y basado en un diseño ex post facto, con el objetivo de analizar el impacto que ha tenido el confinamiento por COVID-19 en el desempeño de los escolares (de 3 a 12 años de edad). Un total de 529 participantes completaron el cuestionario CIEN (Cuestionario sobre el Impacto Educativo en la Infancia) sobre impacto educativo de la COVID-19 en sus hijas e hijos escolarizados en España. Los resultados arrojaron un modelo robusto basado en ecuaciones estructurales que explicó el 39,7% de la varianza en el desempeño escolar en casa, siendo la relación familia-escuela, la variable que reveló mayor peso explicativo (?=.505; p<.05). En conclusión, los beneficios derivados de una relación entre la familia y la escuela, patente en el establecimiento de lazos de comunicación y cooperación, facilitan el afrontamiento de retos educativos compartidos tales como la educación a distancia en tiempos de COVID-19.

Émigré belge arrivé à New York au milieu des années 1950, Luc Sante a fait divers petits boulots avant de travailler au service du courrier de la New York Review of Books , dont il n’aura cessé de « détourner » des ouvrages pour son propre intérêt. De fil en aiguille, il devient chroniqueur culturel, conteur de la vie quotidienne du New York prolétaire, critique photo, éditeur pour la Library of Larceny — une collection consacrée aux vies de délinquants et d’escrocs — pour finir observateur désabusé de la gentifrication de sa ville d’élection, et professeur à quelques centaines de kilomètres au nord de celle-ci, où il a fini par déménager. Le texte que vous allez lire est extrait d’une histoire qu’il a construite en sept parties, « E.S.P. », publiée en 2020 dans son livre Maybe The People Would Be The Times chez Verse Chorus Press. En très peu de temps, Sante fait résonner ensemble la musique de General Echo, l’ambiance sociale d’un club et l’effet d’une danse.

Ce que la scène techno peut apprendre de l’autonomie italienne
Authors: Kabuiku Jean-Hugues
Published: October 2021

Cet article reprend et prolonge une publication en anglais au sein du média américain Dweller , qui met en avant une perspective noire sur l’histoire de la techno et la club culture contemporaine. Le site aborde des conflits locaux, à Berlin, Amsterdam, New York, Le Cap, ou Johannesbourg, notamment la discrimination, l’exclusion ou l’exploitation des Noirs et des queers dans les clubs, qu’ils soient artistes, publics ou travailleurs, ainsi que des questions plus générales comme le blanchiment de la techno et l’appropriation culturelle, le rapport entre identification noire et diaspora musicale, ou les effets du capitalisme urbain. Le texte que vous allez lire reprend et étend une réflexion qui se concentrait sur la politique culturelle pendant la crise du Covid-19 aux États-Unis et en Allemagne, afin d’entamer un dialogue international entre les scènes américaine et européenne et d’échanger des pratiques. Son auteur, le DJ, musicien et auteur Jean-Hugues Kabuiku, s’y montre passablement remonté par ce qui s’est produit ces derniers mois. Pour lui, la parenthèse vécue par le « monde de la nuit » doit permettre d’en repenser la culture et les objectifs politiques. En s’inspirant de l’histoire des luttes autonomes, et en particulier de l’opéraïsme italien, il estime qu’il est possible d’ouvrir des possibilités stratégiques plus radicales que ce que proposent actuellement les organisateurs·trices de soirées et les lobbys animés par des promoteurs. Cet article polémique, qui constitue pour nous une rare incursion dans les débats d’actualité, est loin de proposer des solutions « clés en main » par rapport aux initiatives en cours, mais il représente une position radicale d’autant plus intéressante qu’elle fait aussi écho à certains aspects de luttes récentes, comme Art en grève, ainsi qu’à la réapparition, dans l’intervalle entre l’édition de ce texte et sa parution, des actions de la Coordination des intermittents et précaires.
Qui a inventé le reggaeton ?
Authors: Marshall Wayne , Croze Benjamin
Published: October 2021

Dans la première partie de cette histoire du reggaeton, initialement parue en 2009 et que nous avions commencé à traduire dans notre précédent numéro, nous nous étions arrêtés sur une première tentative de crossover des musiques issues du reggae dancehall et des circulations de grooves entre Porto Rico, Panama et New York : le « meren-rap », une musique rap-reggae-merengue new-yorkaise marketée à destination des classes moyennes. Cette seconde partie en arrive maintenant au reggaeton tel qu’il a conquis les charts américains et européens, dans sa version électronique et hyper-sexualisée. Si on parle souvent d’appropriation culturelle ou de standardisation d’esthétiques locales au moment de leur popularisation, ces mouvements sont rarement décrits avec la précision qui se dessine ici, quand les collages à cent à l’heure de DJ Nelson laissent la place aux beats programmés sur FruityLoops par les Luny Tunes. Ce qu’il y a de plus précieux dans cet article est sans doute la façon dont Marshall profite de ses connaissances de musicologue, d’amateur et d’historien pour établir ce qu’il appelle une « politique culturelle » du reggaeton. Il est capable de nommer sa part de sexisme tout en parant au moralisme puritain, de dire ce qui s’est « perdu » dans ses dernières versions transnationales sans rejeter en bloc les nouvelles formes qui sont produites, de décrire la standardisation sans réinventer un passé purifié et sans en bouder les plaisirs.
Remédiation orthophonique par la musique
Authors: Commeiras Céline , Dormoy Alice , Habib Michel
Published: October 2021

Après un aperçu des recherches neurocognitives montrant les bienfaits de jouer et d’écouter de la musique chez les enfants « dys », ce chapitre présente un exemple de remédiation cognitivo-musicale de la dyslexie en partant du principe que la dyslexie se conçoit comme un déficit de mise en relation des engrammes sensorimoteurs de la parole avec la représentation auditive des phonèmes de la langue et un défaut de mise en relation des formes auditives et visuelle des lettres et des mots. C’est donc la manifestation d’une dys-connectivité entre différentes régions corticales. La pratique musicale peut y remédier en favorisant la connectivité des régions du cortex qui peinent à communiquer entre elles.
Émergence de la prison moderne en Haïti : discours, pratiques, institutions
Authors: Dandoy Arnaud , Edouard Roberson
Published: October 2021

Cet article explore la façon dont le nouvel État d’Haïti s’est approprié la question carcérale au lendemain de son indépendance. Nous analysons le système carcéral au cours de la période allant de 1804 à 1915 sur un triple plan : les idées, les pratiques et leur institutionnalisation. Nous commençons par retracer la sociogenèse de la prison nationale haïtienne en ayant soin de mettre en relief les facteurs sociopolitiques et économiques qui ont contribué à sa création. Notre attention se porte ensuite sur le régime carcéral instauré dans les prisons après l’indépendance et sur sa rationalité. Nous nous appliquons enfin à montrer comment le discours de la réforme pénitentiaire a percolé dans les débats d’idées (académiques et politiques), mais sans jamais réussir à infléchir le cours des pratiques judiciaires et pénitentiaires et leur sédimentation dans des normes et des habitudes organisationnelles et professionnelles le plus souvent préjudiciables aux détenus. La généalogie de la prison haïtienne lève le voile sur son impasse en rétablissant la filiation entre elle et son héritage colonial, malgré son discours moderne. Elle a pour but d’enrichir les connaissances en histoire des savoirs sur la peine et sur la prison en particulier.
« Histoire d’une mobilisation ». Dynamiques de mobilisation locales et influences internationales au sein de trois communautés libyennes
Authors: Badi Emadeddin
Published: October 2021

Le contexte géopolitique libyen actuel résulte, d’une part, d’une multiplicité d’acteurs internationaux poursuivant leurs intérêts propres, mais aussi de fragmentations aux niveaux local et national, qui déterminent souvent les dynamiques de mobilisation (et de démobilisation) des acteurs armés. Pour mieux saisir la complexité de ces enjeux, cet article aborde trois études de cas : les milices de Tripoli, les groupes armés de la ville de Misrata et l’Armée arabe nationale libyenne de Khalifa Haftar – à travers lesquels sont explorées différentes dynamiques de mobilisation dans des oligopoles de violence. Contrairement à la présence symbolique d’un monopole sur la violence et à la présence d’ordres de gouvernance fondés sur des lois dans l’« État idéal », les oligopoles de violence se caractérisent par une multiplicité d’acteurs locaux intégrant la violence à leur mode opératoire, et bénéficiant de différents degrés de légitimité. Ces acteurs peuvent rivaliser ou coopérer les uns avec les autres, mais aussi avec l’État. À chaque cas d’étude sélectionné correspond une dynamique distincte concernant les rivalités de pouvoir entre les principaux acteurs, et ce à plusieurs niveaux : groupes armés, institutions officielles et sponsors régionaux. À travers l’étude de ces différents oligopoles, les intersections entre les échelles communale, locale, nationale et internationale démontrent qu’un cadre analytique centré sur l’État peine à analyser une telle confluence de politiques internationales et de dynamiques communautaires susceptibles de déclencher les mobilisations ou d’engendrer la fragmentation des groupes armés. Cet article examine donc de manière critique le rôle et les stratégies des acteurs internationaux dans le déclenchement, l’appui ou la fragmentation de ces processus de mobilisation, ainsi que leurs impacts sur les rivalités locales. Pour ce faire, est utilisé le cadre théorique des Critical Security Studies (études critiques de sécurité) pour analyser ces phénomènes à différents niveaux.
Psychopharmacology of Pediatric Attention-Deficit/Hyperactivity Disorder
Authors: Greydanus Donald E. , Rowland Dustin C. , Patel Dilip R. , Soares Neelkamal
Published: October 2021

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder identified in 4% to 8% of children, adolescents, and adults. Features of ADHD found in childhood and adolescence persist into adulthood in as many as 70% of pediatric patients with this diagnosis. Various behavioral therapies are helpful for ADHD. This discussion focuses on medications that research has shown to be beneficial for treating the core features of this condition. Drugs that are approved by the US Food and Drug Administration for ADHD are psychostimulants (methylphenidate and amphetamine products), long-acting alpha-2 agonists (clonidine, guanfacine), and a selective norepinephrine reuptake inhibitor (atomoxetine). Clinicians prescribing these drugs should monitor their patients for both beneficial and adverse effects. Although it is often difficult to find a specific medication that is superior to others for all people with ADHD, research does show that methylpheni-date is typically superior to amphetamines. Thus, careful clinician scrutiny is needed to find the optimal formulation for those taking these medications.

Management of Common Psychiatric Illnesses on Pediatric Medical Floors
Authors: Latif Finza , Albreiki Mohamed
Published: October 2021

Pediatric consultation-liaison (CL) psychiatry focuses on the treatment of mental health difficulties in physically ill children. This article focuses on three diagnoses that a pediatric CL psychiatrist commonly encounters: delirium, somatic symptom and related disorders (SSRD), and pediatric medical traumatic stress (PMTS). Delirium is an acute cerebral dysfunction secondary to an organic cause and can present with agitation, sleep disruption, disorientation, inattention, perceptual disturbances or apathy, and withdrawal. The management of delirium involves the treatment of underlying medical causes by environmental modifications and pharmacological strategies. SSRDs present with medically unexplained symptoms in which physical examination and laboratory testing do not justify a diagnosis of a known medical illness. Cognitive-behavioral therapy has the most evidence for the treatment of SSRDs, whereas pharmacological interventions have insufficient evidence in improving core symptoms of SSRDs. PMTS is defined as a set of posttraumatic stress symptoms (PTSS) in response to pain, injury, serious illness, medical procedures, and invasive or frightening treatment experiences. Brief, focused cognitive-behavioral strategies delivered in a family-centered approach can prevent or reduce symptoms.

What is It Like To Be a Bat in the Time of Covid-19, or How Many Pandemics Could We Have?
Authors: Goran Đurđević  , Suzana Marjanić
Published: October 2021

In these paired years (2020–2021), the whole world has been impacted by the Covid-19 pandemic, which has resulted in the emergence of different presumptions, alternative facts, and fake news. Among those, the most dominant news was about bats as the culprits of expansion of the virus and, indirectly, the Chinese diet as the root cause. However, there is no proof that the links in the triangle of bat-virus-human are valid; and the source of infection has not been identified. In addition to bats, these viruses can be found in other animals, such as camels, pangolins, and humans. Therefore, individual scientists are reversing the situation by presenting the possibility of transmitting the virus from humans to animals. Nevertheless, it has become ultimately ‘acceptable’ to demonise the bat. In this respect, various authors remind us of certain historical contexts of notions and perceptions of the bats, as well as the similarities and differences of those perceptions during the pandemic, referring to it mainly in the context of Croatia and the world. In the end, the article’s conclusion is that the story about the bats is, actually, a great indicator of the representations of Otherness and the strengthening of a binary and hierarchical division of ‘us’ and ‘them’.
Tudi stari Slovani so poznali gnomone
Authors: Andrej Pleterski
Published: October 2021

The belief that only written records of ancient Greek science are relevant to our knowledge of past science and that there is nothing outside of that knowledge that is not contained in written sources is misleading. The ancient Slavs were able to develop their knowledge of mathematics and astronomy independently of ancient Greek science. Neglecting the knowledge of the ancient Slavs in comparing it with that of the ancient Greeks is misguided and cannot lead to useful findings.
Angioma sepiginosus: two cases in children and review of literature

Published: October 2021

Angioma serpiginosum (AS) is a rare benign vascular lesion that typically arises in early childhood, with a prevalence in female, and then grow up over a period of months/years. It is characterized by small asymptomatic purple-red dots that cluster together and they do not disappear on diascopy. It is mainly localized on the arms but some cases on face and neck have been reported. The etiology of AS is unknown, dermoscopy may aid in the diagnosis but usually the biopsy is necessary. We report 2 cases: one male and one female with angioma serpiginosum, aged 13 and 8 years old.

Dear Editor, Localized scleroderma (LSc; morphea) is a rare fibrosing disease of the skin and underlying tissues, which is different from systemic sclerosis (SSc). 1 LSc is classified based on clinical presentations: circumscribed, linear, generalized, pansclerotic, and mixed morphea. 1 Generalized morphea (GM) , which is characterized by widespread skin lesions with multiple indurated plaques or hyperpigmentation, is a relatively rare subtype occurring in 7-9% of patients with LSc. 1 Previous studies have shown that SSc can be complicated by GM, separately from GM-like SSc. Here, we present a rare case of coexistence of LSc and SSc in which LSc skin lesions appeared before SSc became apparent [...].

Published: October 2021

Stressful situations such as the COVID-19 pandemic can serve as a niche for developing pathological mental state or influence the symptomatology of patients with psychiatric disorders. Here, we present four such cases. Three cases highlight the onset of psychosis precipitated by the immense stress posed by the pandemic. In the last case, psychopathology of a patient with preexisting mental illness getting influenced by the pandemic is highlighted. In all the four cases, it is interesting to note that delusional work is weaved around the COVID-19.
Awareness among parents of individuals with intellectual disability about sexual health education
Authors: Saini Ravinder , Ahmad Wasim , Nazli
Published: October 2021

Background:

Most of the parents have no idea that how and when they should educate about sexual health to their typically growing children. It is important for parents to educate their children with intellectual disability about sexual health. The risk of sexual exploitation and abuse is very high in individuals with intellectual disability.

Objective:

The present study was conducted to find out the awareness among the parents of individuals with intellectual disability about sexual health education.

Materials and Methods:

Subjects for the present study were the parents of individuals with intellectual disability studying at government rehabilitation institute for intellectual disabilities, chandigarh (n = 100). The present study is a cross-sectional study and subjects were selected by making use of random sampling technique. A Rating scale on “Awareness on sexual health education for parents of intellectually challenged children” developed by Lakshmi and Navya, (2014) was used.

Results:

The results revealed that there is a significant difference in knowledge, attitude, and practice among the parents of individuals with intellectual disability about sexual health education. The significant difference with respect to the gender on awareness about sexual health education (knowledge, attitude, and practice) among the parents of individuals with intellectual disability was found. No significant difference with respect to family type on awareness about sexual health education was found.

Conclusion:

Parents who live in rural locality have responded greater on the knowledge and practice than those who live in urban locality. However, parents living in urban locality have scored more on attitude over the parents who live in rural locality.

Published: October 2021

OBJECTIVES: An A/H5N1 vaccine (IVACFLU-A/H5N1) was accepted for use in Vietnam; however, antibody persistence after vaccination has not been well characterized. We examined post-vaccination antibody persistence and related risk factors in individuals enrolled in the phase II IVACFLU-A/ H5N1 vaccine trial in Ninh Hoa, Vietnam, who received a 15-μg dose (2 injections 21 days apart).METHODS: We used a longitudinal study design to follow 86 participants, without a control group. The participants tested as anti-A/H5N1 immunoglobulin G seronegative at baseline and received both doses of the vaccine. Blood was drawn at 30 months and 36 months after the complete vaccination to assess antibody status. Antibody persistence status was compared by demographic characteristics and exposure risk factors using univariate logistic regression.RESULTS: In total, 84.9% and 52.3% of the population showed persistence of at least 1/10 of the A/H5N1 antibodies at 30 months and 36 months after IVACFLU-A/H5N1 vaccination, respectively. The odds of antibody persistence were higher in older people, but lower in people who had experienced flu-like symptoms in the past 18 months or between 2 visits. We recorded no differences between A/H5N1 antibody persistence and exposure risk factors, including having a poultry farm, coming into contact with poultry, and slaughtering and processing poultry.CONCLUSIONS: This study demonstrated noteworthy antibody persistence, indicated by the seroconversion rate and geometric mean titer at 30 months and 36 months after the IVACFLU-A/H5N1 vaccine. Further studies should investigate older people and those who experienced flu-like symptoms to determine a suitable time for a booster shot.

Published: October 2021

With the goal of ensuring the security of passengers for automotive industry, the present work addresses the ductile fracture process of plasticized PVC. Dedicated clamped single edge notch bending (SENB) specimens were used to characterize the mechanisms of crack initiation and propagation for the studied material. The exploitation of the experimental database associated with finite element simulation of the crack propagation allowed, on the one hand, the calibration factor ηp of this specific SENB specimen to be established, as a function of the crack depth ratio. On the other hand, the fracture toughness of the studied plasticized PVC was estimated to be 10.8 kJ/m2, value which was close to that reported in the literature for modified PVC. By using this fracture toughness value, a methodology aiming at the prediction of ductile crack initiation of the PVC skin integrated into a real dashboard (full scale test) was proposed.

O conhecimento das gestantes sobre a importância do cuidado com sua higiene bucal e do bebê contribui para redução de doenças bucais e obtenção de hábitos saudáveis desde a gravidez. Este estudo teve como objetivo avaliar o conhecimento sobre saúde bucal de gestantes, bem como os fatores associados a esse conhecimento. Trata-se de um estudo transversal, com abordagem quantitativa, realizado com 196 gestantes. Dois questionários foram preenchidos, com o primeiro abordando aspectos sociodemográficos e econômicos e o segundo relacionado ao pré-natal e conhecimento sobre a saúde bucal do bebê. Os escores de conhecimento foram comparados por meio dos testes Mann-Whitney e Kruskal-Wallis. O nível de significância adotado no estudo foi de 5% (α = 0,05). As gestantes do grupo etário de 31 a 44 anos, com ensino superior, com renda familiar maior que 3 salários mínimos e que achavam necessário ir ao dentista durante a gravidez apresentaram maior escore de conhecimento, quando comparadas aos seus pares. O conhecimento sobre a saúde bucal das gestantes e do bebê ainda é muito limitado a alguns grupos sociais.
Impact of COVID-19 on People with Disabilities
Authors: Pant Smriti , Koirala Saugat , Subedi Madhusudan
Published: October 2021

Any condition of the body or mind that makes it more difficult for the person with the condition to do certain activities and interact with the world around them is known as a disability. Despite the various efforts being done to ensure their rights and equity of the disabled, they still suffer more during various crises like conflicts, natural disasters and pandemics. The purpose of this narrative review is to access the impact that the COVID-19 pandemic has had on People with disability (PWD). For writing this narrative review, Google, Google Scholar, Pub Med and online news portals were searched by using various combination of the following terminologies; “Disability”, “Differently “Disabled”, “Disable”, “People with Disability”, “PWD” “Impact”, “COVID-19”, “Corona Pandemic”, “Challenges”, “Issues”, “Policies”, “Social”, and “increased risk”. The pandemic has created many challenges for people with disability. They not have greater risk of contracting COVID-19, but also have problems accessing health services. It has also had various social impacts like problems related to education, employment as well as discrimination. The COVID pandemic has exposed gaps in the health system that make the poor, marginalized and disabled population more vulnerable to neglect and mistreatment. Proper implementation and monitoring of policies should be done to ensure that PWD feel included and respected. It is important to continually integrate PWD into the mainstream society while minimizing their risks of contracting COVID-19. The caretakers should use the necessary PPE when attending to their needs.

TOURISM INDUSTRY AND THE COVID-19 PANDEMIC: IMPACT AND CONSEQUENCES
Authors:   Lomonosov Moscow State University, Sarafanova A.G. , Sarafanov A.A. ,   Lomonosov Moscow State University
Published: October 2021

The study aims to explore the relationship between the pandemic and the tourism industry. The emergence of infectious diseases is one of the consequences of tourism and mobility of citizens. The article examines the scientific research of foreign authors on the impact of epidemiological diseases on the tourism industry. The pricing strategies of travel companies caused by the policy of curbing the spread of coronavirus infection are analyzed. The authors cite some forms of adaptation of the tourism industry to the conditions of the COVID-19 pandemic (in such countries as Costa Rica, Jamaica, the Republic of Fiji, Finland, Greece, Iceland, Israel, Japan, the UAE, China). A statistical analysis of the tourism development in the Russian Federation (the number of incoming and outgoing tourists, the number of hotels and similar accommodation facilities) was carried out. The COVID-19 pandemic has reoriented the outbound tourist flow to domestic destinations. The advantages of developing domestic trips in comparison with international ones regarding their role in the economic development of regions are presented. The pandemic has led to an inevitable surge in the use of digital technologies due to the norms of social distancing and nationwide restrictions. One of the most popular forms of technological applications in the tourism industry is virtual reality. The use of virtual reality can contribute to the creation of a new, more sustainable model of tourism.

Desde una visión sistémica la gestión del conocimiento afecta al proceso de toma de decisiones en las organizaciones que, en un entorno globalizado, deben plantear estrategias que posibiliten el incremento de la competitividad y productividad. El objetivo es determinar los factores de gestión de conocimiento (GC) en una entidad pública del sector transporte en Colombia que optimizan la prestación de sus servicios, ofreciendo herramientas que facilitan la captura, creación, retención, difusión y uso del conocimiento, tomando como referencia, el análisis relacional de cuatro factores como lo son el manejo de información, la planeación estratégica, la comunicación e incentivos y la gestión tecnológica.
La investigación es de enfoque cuantitativo, con un alcance correlacional y diseño no experimental de tipo transversal. En el análisis de los datos se aplicaron técnicas estadísticas multivariadas. Se realizó un análisis correlacional a través del cálculo del coeficiente de correlación de Sperman, para establecer cómo son las relaciones entre las dimensiones de los factores estudiados y entre cada factor. Luego se validan los factores mediante un analisis de ecuaciones estructurales con estimaciones de máxima verosimilitud. Dentro de los hallazgos destaca que no existe una asociación entre el manejo de información y la gestión tecnológica, lo que limita la gestión del conocimiento organizacional, pero a su vez constituye una oportunidad de mejora para la efectiva ejecución futura de los procesos.

The purpose-on the basis of the analysis of the current state and location of enterprises in the dairy industry of the republic and Almaty region, in particular, to identify the main factors that hinder its development, to develop recommendations for solving the existing problems. Methods - monographic, computational-constructive, analytical, economic-statistical, logical generalization. Results - research confirms the underdevelopment of the infrastructure for effective promotion of dairy products from producer to consumer along the production-processing-sale technological chain, especially primary milk processing; often there is a discrepancy between the required proportions between the existing production capacities of milk processing enterprises and the level of development of their raw material zones. Based on production potential of each district of a specific region and calculation of the population's demand for dairy products, a forecast for creation of agricultural cooperatives (APC) of dairy direction for purification of milk from mechanical impurities, cooling, storage and transportation in the context of districtsis presented. It is necessary to create 77 APC for the period 2021-2022, incl. 64 cooperatives for primary milk processing. Conclusions - it is recommended to merge small farms into agricultural cooperatives. The economic efficiency of organizing a cooperative milk collection point at the district level has been justified. Based on the study of the existing schemes for location of milk processing enterprises, proposals have been developed for the localization of new cooperative milk collection points in the territorial units of the region. Dairy industry enterprises need investments to renew their fixed assets. The authors note that the possibilities and advantages of cooperative principles and the potential reserve of agricultural cooperation are not yet fully realized.

The agro-industrial complex of Kazakhstan has the objectives on increasing the volume of production of competitive, export-oriented agricultural products and increasing labor productivity by 2.5 times by 2022. Thus, the country's agricultural policy is aimed at ensuring food security. The goal -is to analyze the current state of providing the population of the republic with food at the expense of own production and to identify further ways of its development. Methods – comparative analysis, statistical and economical for market research; systematic approach. Results - The Ministry of National Economy of the Republic of Kazakhstan dated December 9, 2016, No.503, approved scientifically grounded physiological norms of food consumption. In connection with the pandemic, the State has set the priority anti-crisis tasks to achieve the stability of the socio-economic development of Kazakhstan, including regulation of prices for agricultural products. The conducted comparative analysis showed that the population in the country is mainly provided with domestic food products within the established standards, with the exception of poultry meat, cheese, cottage cheese, fruits, berries, vegetables, sugar and fish. The undertaken measures show that in the near future they will allow increasing the scale of production of these food products, which is quite justified. It has been determined that the republic has potential opportunities, in particular, natural and labor resources for import substitution. Conclusions - meeting the needs of the republic's residents for all types of their own products requires deep research. State regulation of agricultural market is aimed at improving the living standards of the population in the regions by creating favorable conditions for the development of crop production, animal husbandry, food industry, social infrastructure, and technical equipment.

По данным международных центров потребление питьевой воды испытывает бурный рост. К 2025 году две трети населения планеты столкнутся с нехваткой пресной воды. В настоящее время одной из причин массовой миграции людей из развивающихся стран в Европу, США и Канаду является отсутствие постоянных источников питьевой воды. Пресная вода становится ключевым фактором геополитики 21 века. Использование главного ее источника – запасов недр – является востребованным и актуальным. Целью исследования является решение проблем эффективного извлечения подземных вод путем создания условий для нормального проявления внутренней энергии водоносных пластов в сочетании с физическими принципами отбора воды, а также возможности и целесообразности применения струй высокого давления в буровых долотах, армированных PDC, для бурения пород VII-VIII категорий по буримости. Методы исследований: использован экспериментально-аналитический метод исследований на экспериментальной установке циркуляционной системы с возможностью визуального наблюдения за режимом движения воды, а также установление ресурсных возможностей циркуляционной системы разработки залежей подземных вод инжекционно-принудительным самоизливом. Существующая методика разведки и освоения месторождений подземных вод бурением вертикальных скважин морально устарела. Применяемые способы проводки скважин в целом не соответствуют геолого-техническим условиям подземных водных объектов, что приводит к технологическим осложнениям и низкой водоотдаче массива. Повышение эффективности вскрытия и освоения залежей подземных вод достигается при создании условий для проявления внутренней энергии водоносных пластов в сочетании с физическими принципами отбора воды и подъема ее на высоту без затрат энергии. Результаты исследований.На основании анализа и обобщения результатов аналитических и лабораторных исследований ресурсных возможностей предложена циркуляционная система разработки залежей подземных вод инжекционно-принудительным самоизливом; установлена целесообразность оснащения нисходящего ствола компоновкой гидроструйного аппарата, ориентированного на элементы залегания водоносных пластов. Зарождение неполного гидроудара в компоновке гидроструйного гидроаппарата создает динамическую депрессию на водоносные пласты с эффектом инжекции и силы гидротарана. Предлагаемая циркуляционная система может быть использована для извлечения воды из низконапорных водоносных пластов.
