Stability and Bayesian Consistency in Two-Sided Markets
Authors: Liu Qingmin
Published: July 2020

We propose a criterion of stability for two-sided markets with asymmetric information. A central idea is to formulate off-path beliefs conditional on counterfactual pairwise deviations and on-path beliefs in the absence of such deviations. A matching-belief configuration is stable if the matching is individually rational with respect to the system of on-path beliefs and is not blocked with respect to the system of off-path beliefs. The formulation provides a language for assessing matching outcomes with respect to their supporting beliefs and opens the door to further belief-based refinements. The main refinement analyzed in the paper requires the Bayesian consistency of on-path and off-path beliefs with prior beliefs. We define concepts of Bayesian efficiency, the rational expectations competitive equilibrium, and the core. Their contrast with pairwise stability manifests the role of information asymmetry in matching formation. (JEL C78, D40, D82, D83)

Authors: Ahmad Munir , Rehman Abdur , Adnan Mudasser , Surani Muhammad Khalil
Published: July 2020

Objective: To determine the incidence of acute bilirubin encephalopathy (ABE) and its risk factors in neonates presenting with hyperbilirubinemia in a tertiary care children hospital.

Methods: This descriptive observational study was conducted from June 2018 to June 2019. A total of 300 infants who were admitted in neonatal ICU with diagnosis of hyperbilirubinemia in The Children’s Hospital & The Institute of Child Health, Multan, Pakistan were included in this period. Incidence of ABE was noted. ABE was divided into two categories on the basis of severity of symptoms; mild ABE and moderate to severe ABE. Total serum bilirubin (TSB) in all neonates was measured in all patients in hospital laboratory using colorimetric method. ABO incompatibility and Rh factor incompatibility was also noted for each neonate.

Results: Out of 300 neonates who presented with hyperbilirubinemia, ABE was diagnosed in only 42 (14.0%) neonates (mild ABE in 17 (5.7%) and moderate in 25 (8.3%). Out of 42 neonates of ABE, total serum bilirubin levels were 20-29.9 mg/dL in 24 (40.5%) neonates, and >30 mg/dL in 18 (42.8%) neonates. Pre-term birth was a significant risk factor of ABE; 23.8% in ABE and 10.70% in non-ABE (p-value 0.01). During treatment, 02 (4.76%) neonates expired due to ABE.

Conclusion: In present study, ABE was diagnosed in 14.0% neonates who presented with hyperbilirubinemia. We found pre-term delivery as a significant risk factor of ABE.

Centromere-specific antibody-mediated karyotyping of Okinawan Oikopleura dioica suggests the presence of three chromosomes
Authors: Liu Andrew W. , Tan Yongkai , Masunaga Aki , Plessy Charles , Luscombe Nicholas M.
Published: July 2020

Oikopleura dioica is a ubiquitous marine tunicate of biological interest due to features that include dioecious reproduction, short life cycle, and vertebrate-like dorsal notochord while possessing a relatively compact genome. The use of tunicates as model organisms, particularly with these characteristics, offers the advantage of facilitating studies in evolutionary development and furthering understanding of enduring attributes found in the more complex vertebrates. At present, we are undertaking an initiative to sequence the genomes of Oikopleura individuals in populations found among the seas surrounding the Ryukyu Islands in southern Japan. To facilitate and validate genome assemblies, karyotyping was employed to count individual animals’ chromosomes in situ using centromere-specific antibodies directed against H3S28P, a prophase-metaphase cell cycle-specific marker of histone H3. New imaging data of embryos and oocytes stained with two different antibodies were obtained; interpretation of these data lead us to conclude that the Okinawan Oikopleura dioica has three pairs of chromosomes, akin to previous results from genomic assemblies in Atlantic populations. The imaging data have been deposited to the open-access EBI BioImage Archive for reuse while additionally providing representative images of two commercially available anti-H3S28P antibodies’ staining properties for use in epifluorescent and confocal based fluorescent microscopy.

На современном этапе развития российской экономики становится очевидным, что любое предприятие для сохранения финансовой устойчивости и долгосрочной конкурентоспособности должно отвечать требованиям окружающей действительности [13]. Одной из наиболее развивающихся отраслей экономики является рынок связи и телекоммуникаций, что во многом связано с современным трендом – цифровая экономика [1], а в частности, с национальным проектом «Цифровая экономика в Российской Федерации». Потребность в оценке финансового состояния и прогнозирования его изменений испытывает как сам экономический субъект, так и его контрагенты, инвесторы и другие заинтересованные пользователи отчётности. Как следствие, выявление неблагоприятных тенденций развития предприятия, рисковых факторов, приводящих к банкротству и методов их оценки, приобретают первостепенное значение. Но, несмотря на большое количество различных моделей оценки степени риска банкротства, в современной экономической науке нет единого формализованного подхода, каждая модель опирается на свою группу показателей и нормативных значений. Именно поэтому для получения объективной информации о финансовом состоянии предприятий сотовой связи необходимо использовать модели различных авторов. Помимо этого следует рассмотреть показатели, необходимые для прогнозирования финансовой несостоятельности исследуемых субъектов, а также разработать возможные их модификации, применимые непосредственно к телекоммуникационной отрасли. Приведённый порядок действий, безусловно, помогает выявить слабые места в деятельности исследуемых экономических субъектов, а вместе с этим, выяснить, смогут ли крупные участники рынка связи, такие как, как ПАО «Мегафон», ПАО «МТС», ПАО «Ростелеком», стать основополагающими, с помощью которых удастся реализовать национальный проект в Самарской области.Цель: оценить возможность применения известных методик прогнозирования банкротства и финансовых коэффициентов к крупным телекоммуникационным компаниям Самарского региона.Метод или методология проведения работы: в статье использовались экономико-математические методы, а также статистические методы анализа.Результаты: оценена возможность применения представлена известных методик прогнозирования банкротства к телекоммуникационным компаниям региона. Представлена скорректированная формула собственных оборотных средств, которая учитывает отраслевые особенности участников рынка связи, тем самым показывает их реальное финансовое положение.Область применения результатов: полученные результаты целесообразно применять экономическим субъектам телекоммуникационной отрасли экономики.
FAZENDO ANA PAZ: A METAFICÇÃO NO FAZER LITERÁRIO DE LYGIA BOJUNGA
Authors: Gamboni Gabriela Trevizo
Published: July 2020

Esse artigo tem por objetivo estudar a metaficção na  obra  Fazendo Ana Paz (1991) de Lygia Bojunga, além de estabelecer suas correlações no tocante ao emprego das estratégias autorreferenciais. Almejamos refletir acerca desse recurso como motivador e instigador de um leitor mais reflexivo e crítico, haja vista que, ao se deparar com narrativas metaficcionais, ele não será um mero consumidor, mas, sim, um colaborador na construção dessas narrativas. A participação do leitor nessa (re)construção do texto literário acaba por ser um convite a experimentar os bastidores da produção artística, incitando-o a tornar-se mais reflexivo e a realizar  uma leitura menos ingênua. A metaficção gera certa instabilidade, pelo deslocamento do foco de atenção para o processo de criação da narrativa, muda-se o foco da história contada para o como essa história é contada. Além disso, o papel do leitor também é alterado, pois aqui ele passa a ser coautor, um colaborador do processo. Pensando em tais implicações, trazemos Fazendo Ana Paz (1991) uma vez que nos adentramos na ficção a partir de uma autora que, com um tom informal, conta ao seu leitor como surgiu a necessidade de escrever, expondo seu fazer literário, situando o leitor pelos caminhos da construção de suas narrativas, e também a confecção de seus personagens, deixando “à mostra” todo o processo.Palavras-chave: Metaficção; Lygia Bojunga; Criador; Criatura.

a formação continuada e a experiência ética do corpo na produção do currículo da educação infantil
Authors: Lopes Sammy William
Published: July 2020

The paper addresses the problem of continuing education of teachers in early childhood education in contemporary times, asking how to elaborate formative pathways that do not focus exclusively on the models/standards of professionalization predetermined by academic production, and later adopted by government policies. It is organized from the investigative movement traced with the teachers who participate in the extension-research project UERJ-EDU-DEDI, coordinated by the author. It critically analyzes the main causes that justify the failure of the training projects established based on the aforementioned models of professionalization and points out conceptual possibilities to think more immanent formative processes, that is, produced from the experiences that unfold itself in the curricular movement, experiences in which teachers try to build more ethical educational relationships with childhood. It concludes that the formative movement needs to be configured as space-time for the expression and collective evaluation of the ethical-educational potentialities engendered in these experiences. The work is conceptually aligned with Gilles Deleuze's philosophy of difference, especially the reading he performs of Baruch Spinoza's "Ethics". It is methodologically guided by the monitoring the modes of subjectivation cartography traced by the teachers in the process of curriculum production for early childhood education, according to the theoretical guidance provided by Suely Rolnik and Felix Guattari.
ação de desenhar na infância como iniciação aos segredos do mundo
Authors: Richter Sandra Regina simonis , Murillo Márcia Vilma
Published: July 2020

In order to highlight the intimate relationship between imagining, drawing and making worlds, this essay questions the educational meaning of children to initiate in the action of drawing in face of the growing cultural tendency of the body being less and less required to produce senses. The incarnated action of drawing, as an aesthetic action of touching and being touched by the world when transposing the visible limits and entering into the intimacy of worldly invisibility, constitutes an experience that is as recurrent and trivialized in school daily life as it is existentially complex due to its poetic power to enter the invisible and inaugurate worldviews. The historical disqualification of the image and imagination in Western thought, supported by the separation between subjectivity of the body and objectivity of the world, does not allow educational thought to consider the phenomenon of poetic imagination as an existential experience of language insertion in the world from the gesture of drawing. Gesture that finds its specificity in the instant the hand traces and inscribes lines on the surface of the supports as infinitely creative writing. The aesthetic gesture of drawing, temporalized by the rhythm of the body in the emergence of the fabulation that accompanies the repetition of the marks, implies a poetic experience of language that involves the fusion of two senses: that of the gesture in materiality and that of the mark configured in it, marked and cicatrized in the surface of the support by the body’s action that performed it. The approximation between education, arts and childhood allows us to highlight the philosophical and pedagogical tensions that involve the question of poetic imagination and to take another look at the action of drawing in the context of children's education. What emerges, from the dialogue between Gaston Bachelard, Maurice Merleau-Ponty and Jean-Luc Nancy, is the relevance of the educational intention of caring for the vital function of language as an aesthetic and poetic experience that is constituted in the processuality of the body to make something appear that produces and contains presence, that which promotes and expands the existential density of the real.

Geometric method for assessing the shadowing of objects in solar power engineering
Authors: MARKIN Leonid V.
Published: July 2020

This paper describes a geometric model for assessing the effective area of solar panels with regard to their shadowing when the object is illuminated by the solar flow from a given direction. Using energy methods, the flow density, the irradiation created by it, and the exposure in radiant or effective units of measurement were determined. Both physical and mathematical formulation of the problem of assessing the energy efficiency of solar panels using the method of geometric modeling are described. To evaluate energy efficiency, a voxel geometric model was selected that discretizes the computational space. A significant difference in the developed voxel geometric model is that it is multivalued, i.e. uses not a 2-digit, but a 4-digit code. Such ambiguity allows the decisive algorithm to quickly “figure out” the origin of the shadow source when calculating the total effective area of solar panels. The described software implementation of the geometric model, graphical shell, and model verification results can be used in the optimization system for designing spacecraft and other solar energy facilities.

Authors: ASTAKHOV Sergey A. , BIRIUKOV Vasilii I.
Published: July 2020

The article discusses the problems that arise when creating new models of supersonic and hypersonic aircraft, which can be solved by model high-speed ground track tests. Mathematical modelling of the aerodynamic characteristics of an aircraft (test object) placed on a rail carriage and accelerated by the solid fuel rocket engines is performed. The numerical method solves the problem of the motion of a body of variable mass along a rail track. To determine the required length of the rail track, a mathematical model of the ballistic characteristics of the upper stage of the rocket carriage was compiled, calculations were made, and the influence of various factors on achieving the maximum speed of the test object was analysed. An analysis is made of the influence of the total mass of the carriage with the load and engine thrust on the possibility of accelerating the test object to the Mach speed (4-5).

Authors: BABAYTSEV Arseniy V. , RABINSKIY Lev N. , AUNG Kyaw Thu
Published: July 2020

The article presents the results of a study of the contact zone of a thin-walled cylindrical shell located between two parallel rigid plates. The shell under consideration was located with various gaps from the rigid plate and was subsequently subjected to internal pressure. In the course of such a study, experimental, numerical and analytical estimates of the contact zone width were obtained depending on the discharge pressure. The obtained numerical and analytical estimates are tested with experiment. To study the width of the contact zone, depending on the gap, a testing workbench was used. The problem of numerical and analytical modelling was solved by the finite element analysis in the Ansys Workbench system. The solution to transcendental equation was found numerically using the Newton-Raphson method. As a result of experimental, numerical and analytical studies, results were obtained for a plane-oval shell with gaps of 0.5 mm, 1 mm and 2 mm, depending on the applied pressure.
Particularities of mathematical modeling of deformation processes for arched and panel designs of composites with large displacements and rotation angles
Authors: DMITRIEV Vladimir G. , EGOROVA Olga V. , STAROVOITOV Eduard I.
Published: July 2020

In aerospace systems and automotive industry flexible elastic and thin-walled structures are widely used. The adequate mathematical models are in the process of development as well as numerical algorithms for examination of the features of processes of deformation of panel and arch designs with large displacements and arbitrary angles of rotation of the normal. For the discretization of the original continuum problem in spatial variables, the finite difference method can be used with the replacement of differential operators by finite-difference second-order approximations. The computational algorithm for solving a substantially nonlinear boundary-value problem is constructed on the basis of adaptation of the calculation method with construction of an explicit two-layer difference scheme in time of the second order of accuracy. The influence of the boundary conditions on the features of subcritical and supercritical behavior of the elastic arch structure under the influence of the surface load of the “tracking” type is considered.

Authors: KYAW Ye Ko , KUZNETSOVA Ekaterina L. , MAKARENKO Alexander V.
Published: July 2020

The characteristics of power sources affect the performance of autonomous electrically driven systems, such as unmanned aerial vehicles, aircraft missiles, guided bombs, torpedoes, space and aerospace vehicles, controlled gliding parachutes. The creation of control systems for the aircraft flight control surfaces of autonomous mobile objects is an urgent topic in modern research. This article provides how a mathematical model based on integrated approach is developed for an energy-efficient mechatronic module for control systems of promising mobile objects powered by various current sources; a comparison of the energy and dynamic characteristics of mechatronic modules of promising mobile objects for various power options is made. As a result, a new type of integrated power-supply source based on capacitive energy storage with floating charge from a primary chemical source of current has been developed. The proposed approaches, dependencies and algorithms can be used in the design of highly efficient mechatronic control algorithms for autonomous mobile objects of a new generation.
Method for solving plane unsteady contact problems for rigid stamp and elastic half-space with a cavity of arbitrary geometry and location
Authors: LI Yulong , ARUTIUNIAN Aron M. , KUZNETSOVA Elena L. , FEDOTENKOV Grigory V.
Published: July 2020

In the work, the process of unsteady contact interaction of rigid stamp and elastic half-space having a recessed cavity of arbitrary geometry and location with a smooth boundary was investigated. Three variants of contact conditions are considered: free slip, rigid coupling, and bonded contact. The method for solving the problem is constructed using boundary integral equations. To obtain boundary integral equations, the dynamic reciprocal work theorem is used. The kernels of integral operators are bulk Green functions for the elastic plane. Because of straight-line approximations of the domain boundaries with respect to the spatial variable and straight-line approximations of the boundary values of the desired functions with respect to time, the problem is reduced to solving a system of algebraic equations with respect to the pivotal values of the desired displacements and stresses at each time interval. One of the axes is directed along the regular boundary of half-space, the second - deep into half-space.
Development of a light field measuring system with corrected distortion based on imaging analysis
Authors: Zhou Panyu , Kong Lingbao , Wang Junhua , Xu Min
Published: July 2020

A light field microscope can realize three-dimensional measurement through only one exposure by the addition of a critical optical component called a microlens array (MLA). MLA errors will introduce aberrations in the captured image and then affect measurement results. This paper proposes a light field measuring system with aberration correction based on imaging analysis. The effect of MLA errors is investigated and quantitatively analyzed through a series of simulation studies. Aberration correction is realized based on computational imaging, in which an image segmentation and fusion distortion model is employed to correct the distortion, while a gradient-based linear recognition algorithm is used to address MLA rotation errors. Experimental results show that the developed light field measuring system can achieve improved measurement accuracy by correcting aberrations with the proposed algorithms.

have been used as a surface passivation treatment to improve the electrical and optical performance of AlGaN nanowire ultraviolet (UV) light-emitting diodes (LEDs). Enhancements in photoluminescence at 335 nm (49%), optical output power (65%), and electroluminescence (83%), with respect to the as-grown nanowire LED are recorded for the AlGaN nanowire UV LEDs with surface passivation. These enhancements are attributed to the reduced nonradiative recombination on the nanowire surfaces. This study provides a potential surface passivation approach to produce high-power AlGaN nanowire LEDs operating in the UV spectrum.

Published: July 2020

Respiration is monitored in neonatal wards using chest impedance (CI), which is obtrusive and can cause skin damage to the infants. Therefore, unobtrusive solutions based on infrared thermography are being investigated. This work proposes an algorithm to merge multiple thermal camera views and automatically detect the pixels containing respiration motion or flow using three features. The method was tested on 152 minutes of recordings acquired on seven infants. We performed a comparison with the CI respiration rate yielding a mean absolute error equal to 2.07 breaths/min. Merging the three features resulted in reducing the dependency on the window size typical of spectrum-based features.
Evaluation of commercial virtually imaged phase array and Fabry-Pérot based Brillouin spectrometers for applications to biology
Authors: Yan Guqi , Bazir Antony , Margueritat Jeremie , Dehoux Thomas
Published: July 2020

Measuring the complex mechanical properties of biological objects has become a necessity to answer key questions in mechanobiology and to propose innovative clinical and therapeutic strategies. In this context, Brillouin light scattering (BLS) has recently come into vogue, offering quantitative imaging of the mechanical properties without labels and with a micrometer resolution. In biological samples, the magnitude of the spectral changes are typically of a few tens of MHz, and the ability of modern spectrometers to monitor such subtle changes needs to be evaluated. Moreover, the multiplicity of variations in optical arrangements, specific to each lab, requires to set a standard for the assessment of the characteristics of BLS systems. In this paper we propose a protocol to evaluate the precision and accuracy of two commercial spectrometers that is reproducible across labs. For a meaningful comparison, we coupled the spectrometers to the same microscope and to the same laser. We first evaluated the optimum acquisition time and laser power. We evaluated the precision using pure water samples. We determined the accuracy by probing water solutions with increasing concentration of salt and comparing it with theory. Following these quantifications, we applied the VIPA-based spectrometer to tumor spheroids engineered from different cell lines that possess different metastatic potentials and resistance to therapies. On these models, we detected significant changes in the linewidth suggesting that BLS measurements of the viscosity could be used as a read-out to distinguish different levels of drug resistance.

Published: July 2020

We report on the crystal growth, structure, thermal, spectral properties, and laser performance of a novel disordered crystal, Yb3+-doped CaYAl3O7 (Yb: CYAM). The complete set of anisotropic thermal properties were systematically studied. Due to the random distributions of Y3+ and Ca2+ ions, the internal disordered structure determines a significant broadening of the absorption (FWHM=25 nm) and emission (FWHM=60 nm) bands. Polarized absorption, emission and gain cross-section spectra are determined. A maximum σem at 1011 nm for π polarization was calculated to be 0.57 × 10−20 cm2. CW laser operation at 1.06 µm with the c-cut sample has been demonstrated. A maximum power of 505 mW was achieved at 1026.5 nm, corresponding to the slope efficiency and optical conversion efficiency being 12.5% and 6.7%, respectively. Yb: CYAM crystal reveals its superiority and potentiality in the ultrashort pulse laser field.
Active dual-tunable broadband absorber based on a hybrid graphene-vanadium dioxide metamaterial
Authors: Li Hui , Yu Jiang
Published: July 2020

In this paper, we demonstrated an active dual tunable broadband terahertz absorber with polarization-independent characteristic, which consists of a hybrid graphene-vanadium dioxide (VO2) metasurface array and a VO2 ground plane separated by a dielectric layer. Numerical simulation results indicate that there are the most distinctive broad absorption spectra and a bandwidth with an absorptance over 90% as wide as 1.7 THz. Blue shift occur in the perfect absorption peaks of the absorber, which shift 1.18 THz from 0.1 eV to 0.6 eV by adjusting the Fermi energy of graphene. Additionally, by using external stimuli to change the conductivity of the VO2, the corresponding absorptance can be continuously adjusted from 28% to 99%, indicating that we can modulate the amplitude on the absorption spectrum. Therefore, we can achieve the tunable property in both frequency and amplitude through an external stimulus on the proposed simple structure. The electric field distribution and impedance matching theory can be explained the inherent physical mechanism. The absorber is effective to reach a 0°∼75° range of incident angles for both TE and TM polarizations. It indicates that the proposed absorber is beneficial to a new design method for high-performance terahertz devices.

From Enclave to Counterpublic: Doubled Rhetorical Space and the Civil Rights Mass Meeting
Authors: Miller Elizabeth Ellis
Published: July 2020

This essay considers civil rights mass meetings as rhetorical events that operated with doubled purpose. Surveying three 1960s civil rights scenes, the study reveals how meetings provided spaces to recharge and regroup at the same time that they functioned as sites for countermovement engagement. Centering attention on this fluid movement among purposes offers insights into strategies activists devised for double-voicing. For the speakers and meetings analyzed here, metonymy, parrhesia, and religious reframing provided rhetors with modes for exploiting outsiders’ presence at these events while continuing to use the meeting for their own ends.

Wirtschaftswunder und Mangelwirtschaft
Authors: Krüger Kai
Published: July 2020

Aktuelle Schulbücher erzählen eine Erfolgsgeschichte der »Sozialen Marktwirtschaft«, welche die Forschung der letzten 40 Jahre kaum berücksichtigt und seit Jahren als überholt gilt. Anhand der Darstellung des »Wirtschaftswunders« und der Planwirtschaft liefert Kai Krüger nicht nur einen Überblick der Wirtschaftsgeschichte von BRD und DDR für die Jahre 1945-1973, sondern zeigt auch auf, dass zeitgenössische Quellen für Schulbücher gezielt verändert werden, damit sie in die deutsche Erfolgsgeschichte passen. Seine Schulbuchanalyse schließt aber nicht bloß auf bewusste Ideologieproduktion oder fehlendes Wissen, sondern auch auf den Konkurrenzkampf unter den Verlagen.
Inklusion im kommunalen Raum
Authors: Trescher Hendrik , Hauck Teresa
Published: July 2020

Inklusion hat immer auch eine räumliche Komponente - doch wie vollzieht sie sich und in welcher Abhängigkeit stehen dabei Raum und (Nicht-)Teilhabe? Diese Fragen sind der Ausgangspunkt für Hendrik Trescher und Teresa Hauck, die qualitative und quantitative Szenarien beschreiben, anhand derer Praxen von Ausschluss und vor allem Inklusionspotenziale offengelegt werden. Diese Betrachtungen nehmen sie im Anschluss an raumtheoretische Überlegungen vor, die Raum als relationalen Vollzugsort von Teilhabe entfalten. Im Ergebnis zeigt sich, dass Teilhabe je situativ in der Auseinandersetzung mit vielfältig bestehenden Barrieren ausgehandelt wird - und es vielfältiges Potenzial gibt, bislang ausgeschlossenen Personen Teilhabemöglichkeiten zu eröffnen.
Beyond the Mirror
Authors: Falkenhausen Susanne von
Published: July 2020

Since the late 1980s visibility has become a currency of social recognition, and a political issue. It also brought forth a new discipline, visual culture studies, and a hotly contested debate unfolded between art history and visual culture studies over the interpretation of visual culture, whose impact can still be felt today. In this first comparative study Susanne von Falkenhausen reveals the concepts of seeing as scholarly act that underwrite these competing approaches to visuality and society, along with the agendas of identity politics that motivate them. In close readings of key texts spanning from the early 20th century to the present the author crosses expertly between American, German, and British versions of art history, cultural studies, aesthetics, and film studies.

PADRÕES ESPAÇOS-TEMPORAIS DA ROTA DO COVID19 (CORONAVIRUS) NO ESTADO DE SANTA CATARINA, BRASIL
Authors: Ribeiro Eduardo Augusto Werneck
Published: July 2020

Este artigo trata-se de uma análise dos padrões espaços temporais do COVID19 em Santa Catarina, Brasil em dois momentos:entre março e abril de 2020. A metodologia aplicada  considerou a configuração e tipificação espacial de seus municípios a partir de dois estudos do IBGE e os casos confirmados dos municípios em Santa Catarina. Não se avaliou o número de casos, nem de óbitos. A partir dos resultados, identificou-se três dinâmicas espaciais distintas (grau de urbanização e concentração populacional), com dois fluxos difusores da COVID19. Com crescimento do número de municípios com casos confirmados e com características distintas entre eles, o cenário futuro implicará planejamento e adequação da infraestrutura de atendimento emergencial diferenciado no enfrentamento da COVID19 no estado de Santa Catarina, Brasil.

Identificou-se os impactos no cotidiano da população mediante escopo encontrado na literatura científica. É um estudo de revisão integrativa, de abordagem qualitativa e de caráter exploratório, realizado nas bases de dados PubMed e Biblioteca Virtual da Saúde (BVS), através do cruzamento dos descritores disponíveis no DeCS (Descritores em Ciências da Saúde): “isolamento social” AND “pandemia” AND “COVID-19”, e em seguida tratados em inglês, de acordo com Medical Subject Headings – (MeSH): “social isolation” AND “pandemic” AND “COVID-19”. Foram usados os seguintes critérios de inclusão: disponibilidade de texto completo, artigos publicados nos últimos cinco anos e disponíveis nos idiomas português, inglês e espanhol; sendo excluídos: artigos repetidos entre as bases de dados, e os que não se enquadram nos objetivos do estudo. Foram encontrados 44 artigos no PubMed e 38 artigos na BVS, que após aplicação dos filtros e leitura minuciosa, restaram 5 artigos do Pubmed e 10 na BVS, totalizando a avaliação de 15 artigos. Dessa forma, conclui-se que o isolamento social trouxe várias repercussões em todos os aspectos, desde os emocionais até o socioeconômico, e desde as atividades laborais/acadêmicas até ao lazer, assim como também implicações positivas no âmbito virtual.
A PANDEMIA DA COVID-19 NA FRONTEIRA AMAZÔNICA: UMA ANÁLISE PRELIMINAR NAS CIDADES-GÊMEAS DE TABATINGA E LETICIA
Authors: Goveia Luís Alberto Miranda
Published: July 2020

O presente artigo é um estudo preliminar que tem por objetivo analisar a pandemia da Covid-19 na fronteira amazônica entre o Brasil e a Colômbia, mais especificamente nas cidades-gêmeas de Tabatinga e Letícia. Para tanto, busca-se identificar os principais decretos emitidos pelo poder público, tanto municipal, quanto estadual e nacional e verificar seus impactos na circulação de pessoas e tráfego aéreo e os resultados na quantidade de infectados e óbitos por essa doença. Os resultados mostram que Tabatinga e Letícia apresentam considerável crescimento no número de infectados pela Covid-19. Conclui-se que a integração desses espaços com outros centros regionais possibilitada pela rede de transporte aéreo e fluvial acabou contribuindo para a entrada do novo Coronavírus confirmando a inserção dessas cidades ao processo de globalização.

O objetivo do trabalho foi analisar a difusão dos casos confirmados da COVID-19 no Amazonas, nos meses de março e abril de 2020. Para isso, foram coletados dados dos casos confirmados e óbitos da FVS/AM, dados da população e características dos municípios (IBGE, 2010; 2019) e dados dos equipamentos em saúde do CNES/DATASUS. Foram realizados mapeamentos das estruturas espaciais e da difusão da doença no software QGIS 3.8. Os resultados demonstraram aspectos coexistentes da difusão hierárquica no início da pandemia no estado e por contágio ao longo do tempo, bem como desigualdades no acesso aos serviços de saúde. Conclui-se que as medidas de isolamento social, as políticas públicas de proteção a população mais vulnerável, recursos humanos e físicos nos serviços de baixa e média complexidade no interior e alta na capital, bem como a logística de transporte para o acesso a saúde são ações que devem ser reforçadas no estado.

Quando surge um novo vírus, com potencial pandêmico, comumente ocorre a partir do contato dos seres humanos com animais silvestres portadores. Nestes casos, o organismo humano não possui mecanismos para combater essa nova infecção, por não ter imunidade natural. Assim, devido à possibilidade de uma alta taxa de transmissão, pesquisadores em todo o mundo buscam estratégias que sejam eficazes contra quaisquer vírus da gripe. Neste artigo, o olhar científico foi direcionado à gestão pública municipal, sendo pertinente compreender de que forma as cidades minimizam a vulnerabilidade das pessoas em seus territórios e, a partir de suas ações, compreender como as medidas tomadas pelo poder público estão contribuindo para o enfrentamento da pandemia gerada pela doença Covid-19. Realizou-se, portanto, um estudo sobre o plano de contingenciamento brasileiro para infecção humana pelo novo coronavírus e, a partir deste, buscou-se compreender quais medidas podem contribuir para a equidade, a justiça social e a cultura de paz. O estudo buscou demonstrar que a adoção de indicadores de sustentabilidade no planejamento pode ser uma forma capaz de minimizar a vulnerabilidade das pessoas e dos lugares, no entanto as cidades brasileiras evidenciaram suas fragilidades, devido aos desafios impostos pela gestão territorial em países em desenvolvimento. Ainda é preciso avançar nas discussões e evidências. Até o momento, o que se sabe é que o distanciamento social é a única forma de evitar o contágio e ser capaz de achatar a curva de contaminação.

Objetivo: caracterizar o processo de difusão espacial da Covid-19 pelos municípios do Estado do Rio de Janeiro. Método: Para análise da difusão espacial dos primeiros casos confirmados de Covid-19 segundo municípios do estado foi utilizada a metodologia de interpolação pelo IDW. Resultados: Foram identificados três eixos principais de difusão no Estado do Rio de Janeiro, todos partindo da Região metropolitana. O primeiro eixo segue em direção a São Paulo pela via Dutra promovendo a difusão pelo Vale do Paraíba. O segundo eixo segue em direção ao Espírito Santo pela BR-101. O terceiro eixo segue em direção a região da cidade de Juiz de Fora em Minas Gerais pela BR-040.Conclusão: A caracterização da difusão da Covid-19 no estado do Rio de Janeiro demostrou seu processo de espalhamento tanto por saltos (seguindo a hierarquia urbana) quanto por contágio uma vez instalada nos novos centros de difusão. A interiorização da difusão impõe a urgente tomada de ações articuladas e solidárias considerando que as políticas de saúde para contenção da Covid-19 se baseiam majoritariamente em medidas não farmacológicas e que a capacidade médico-hospitalar dos municípios de médio e pequeno porte que se encontram nessa rota de difusão é limitada.

O presente artigo objetiva caracterizar e analisar a introdução do vírus SARS-CoV-2, causador da Covid-19, na cidade de Maringá-PR. Maringá é a segunda maior cidade do interior do estado e, como cidade média, desempenha importantes papéis regionais. Estudos e análises preliminares indicam que a doença se dissemina no território estreitamente associada às estruturas espaciais preexistentes. Os eixos econômicos mais vigorosos, identificados pelas rodovias de maior fluxo e as cidades com destacados papeis regionais, que sediam aeroportos com voos comerciais, modulam significativamente a direção e a intensidade nos novos casos. Apesar de se tratar de uma cidade específica no interior do Paraná, no presente texto podem ser reconhecidos padrões espaciais, processos e dinâmicas que conectam e determinam diferentes territórios. Para tratar dessas questões, o texto está composto por três partes: 1) contextualização da situação geográfica de Maringá; 2) caracterização e análise dos dados de casos confirmados e notificados no período de 18/03/2020 a 30/04/2020, e; 3) Análise dos principais fatores de risco à Covid-19 na escala intraurbana. A análise permite concluir que: 1) os primeiros casos confirmados na cidade de Maringá foram importados diretamente do exterior, sem mediação de São Paulo ou Curitiba; 2) No primeiro mês, os casos estiveram fortemente concentrados nas áreas mais valorizadas, onde se situam as classes com os maiores rendimentos; 3) Após o primeiro mês, contado a partir da confirmação do primeiro caso, iniciou-se a tendência de dispersão para as áreas mais vulneráveis da cidade. Esta breve análise fornece importantes características geográficas de processos pandêmicos, sua configuração e dinâmica espacial na escala intraurbana. Além disso, contém elementos importantes para pesquisas futuras não só da Covid-19, mas de eventos de saúde de modo geral.

Published: July 2020

A pandemia de COVID-19 apresenta desafios significativos para o Brasil. O conhecimento geográfico pode contribuir para compreender a dinâmica de distribuição dessa doença e assim compor mecanismos de seu enfrentamento. A partir do recorte da mesorregião sul/sudoeste de Minas Gerais, analisou-se como o novo coronavírus se disseminou nesses municípios, quais os principais nexos geográficos e os riscos. Para isso, analisou-se geograficamente um conjunto de informações como hierarquia urbana, população total e proporção de idosos, casos confirmados e mortes em decorrência da doença, e o papel das vias de transporte. Como conclusão, aponta-se para o destacado papel da estruturação da rede urbana e dos eixos rodoviários na disseminação da COVID-19 no sul de Minas Gerais. Elabora-se também a hipótese a ser verificada por pesquisas posteriores de que os estabelecimentos que margeiam as rodovias (postos de gasolina, conveniência, restaurantes, borracheiros, etc) sejam eixos de disseminação da doença. É proposto ao poder público a manutenção do isolamento social e a instalação de postos de controle nas entradas rodoviárias dos municípios, visando a medição de temperatura e orientação dos cidadãos.
