Effects of platelets on extracellular traps of neutrophils in patients with systemic lupus erythematosus
Authors: Novikova I. A. , Zubkova Z. V.
Published: January 2021

Platelets are central participants in hemostasis, and also contribute to the host inflammatory and immune responses. Platelets are known to have a direct effect on the formation of neutrophil extracellular traps. Moreover, the patients with systemic lupus erythematosus exhibit multidirectional disturbances in the functional activity of platelets and neutrophils. Changes in inflammatory and thrombotic events can be considered predictors for adverse clinical course in systemic pathology. The aim of present study was to evaluate the possible role of platelets in maintaining increased netosis in patients with systemic lupus erythematosus. Blood platelets and white blood cells from 29 patients with systemic lupus erythematosus (SLE) were subject to the study. We have registered the in vitro effects of platelets upon formation of extracellular traps by autologous neutrophils under the conditions of co-cultivation for 30 minutes (vital NETosis) and 150 minutes (suicidal NETosis), as well as the relationships between the platelet counts, their activity and the number of NETs observed. It was found that the severity and direction of the platelets effect upon NETosis in vitro cultures depends on the degree of activity of disease: in the 1st degree of SLE, the effect of platelets did not differ from healthy individuals, i.e., intact platelets suppress NETosis (p = 0.002), whereas ADP-induced patelets did not exert any effect); at the 2nd degree of activity, both intact and activated platelets increase NETotic activity (p = 0.03 and p = 0.04 for intact and activated platelets, respectively). In the patients with 3rd degree of the disease activity, platelets did not affect formation of NETs. Hyperactivation of platelets was detected in SLE patients, mostly pronounced in the cases with 2nd degree of activity. However, we have not revealed any significant relationships between the count of platelets, their functional activity (according to results of ADP-test aggregation), and the indexes of NETosis. At the same time, the counts of neutrophil extracellular traps in bloodstream depended on the concentration of C-reactive protein (r = 0.58; p = 0.02), the titer of autoantibodies (anti-SS-A and anti-SS-B) (r = 0.66; p = 0.04 and r = 0.76; p = 0.02, respectively), rheumatoid factor (r = 0.73; p = 0.007) and circulating immune complexes (r = 0.68; p = 0.02). The obtained results indicate that the platelet/neutrophil interactions are not the leading cause for increased NETs numbers in SLE, compared to significantly higher effects of soluble autoagressive factors.

Mechanisms of recognition and effector responses of immune system upon initiation and maintenance of immune-mediated inflammation and tissue damage in inflammatory bowel diseases, including Crohn’s disease and ulcerative colitis (UC), have been actively studied over recent time. Existing evidence suggests these diseases to be caused by abnormal immune response against intestinal flora microorganisms in genetically susceptible individuals. Despite available data on the features of immune disorders in ulcerative colitis and Crohn’s disease, there are still many questions about the involved minor lymphocyte subpopulations and contribution of various functionally active molecules, which play a key role in recognition and initiation of the immune response and can be considered biomarkers of a pathological process in inflammatory bowel diseases. The populations of T lymphocytes with γδT cell receptor, B1 cells and NK T lymphocytes are of greatest interest, as well as functionally active TLRs (Toll-like receptors), CD89, CD314, etc. Due to substantial progress in studying the nature of recognition and activation of the immune cells, the paper presents phenotypic and functional characteristics of major and minor subpopulations of peripheral blood lymphocytes observed in 25 patients treated at the Surgery Department of the State Institution “Minsk Regional Clinical Hospital” (Republic of Belarus) from 2018 to 2020. The detected changes in peripheral blood lymphocyte phenotype of inflammatory bowel diseases patients suggest distinct immunological profiles prevailing in the damage mechanisms in Crohn’s disease and ulcerative colitis. I.e., in Crohn’s disease patients, B1 lymphocytes with CD19+CD5+ and NK cells in combination with increased CD56bright population, as well as NK T cells with anti-inflammatory and regulatory activity are involved into genesis of the disease. In ulcerative colitis, T, B, NK lymphocytes with pro-inflammatory phenotype and T lymphocytes with γδ T cell receptor may play a pathogenetic role in maintenance of chronic inflammation. With respect to functional significance of activating receptors, the number of TLR4- и CD89-positive cells may be used for developing immunological criteria/ biomarkers of therapeutic efficacy of new drugs. Studying interactions between innate and adaptive immunity will open new perspectives in understanding immunological disorders associated with chronic gastrointestinal inflammation.
Successful long-term prophylaxis of hereditary pregnancy-associated angioedema with plasma-derived C1-inhibitor concentrate: a case report
Authors: Demina D. V. , Makeeva A. O. , Kudelya L. M. , Novikova E. V. , Kozlov V. A.
Published: January 2021

Hereditary angioedema (HAE) is a rare autosomal dominant disease caused by quantitative (type I) or functional (type II) deficiency in C1 esterase inhibitor (C1-INH). It may be caused by new mutations in up to 20% of patients. Prevalence of HAE is uncertain but is estimated to be approximately 1 case per 50,000 persons, without known differences among ethnic groups. C1-INH protein is a serine protease inhibitor that is important in controlling vascular permeability by acting on the initial phase of the complement activation, blood clotting, and fibrinolysis. Deficiency in functional C1-INH protein permits release of bradykinin, a key mediator of vascular permeability. Symptoms typically begin since childhood, worsening at puberty, and persist throughout the life, with unpredictable clinical course. The patients with HAE suffer from recurrent, acute attacks of edema that can affect any body sites, causing potentially life-threatening disorders (laryngeal edema). Results of clinical studies show that minor traumas, stress and medical interventions may be frequent precipitants of swelling episodes, but many attacks occur without an apparent cause. Pregnancy-associated hormonal changes may affect the course of C1-INH angioedema attacks by worsening, improving, or having no impact at all, but a higher percentage of pregnant women experienced an increase in C1-INH-HAE attack rates. Therapeutic options for patients with HAE are limited during pregnancy. C1-INH concentrate is recommended as the first-line therapy for pregnant women with HAE for on-demand treatment, shortterm and long-term prophylaxis, due to its safety and efficiency. Other therapies, e.g., treatment with fresh frozen plasma, androgens, icatibant, antifibrinolytics, may show variable efficacy, or cause undesirable side effects. The case below illustrates the successful treatment of HAE in a pregnant woman with C1 esterase inhibitor (C1-INH) concentrate. This patient had a very mild course of HAE during her lifetime and didn’t get any treatment. During pregnancy, she experienced a significant increase in the frequency of attacks, and the decision was made to start replacement therapy with a plasma-derived, double virus-inactivated C1-INH concentrate as a long-term prophylaxis throughout the full term of her pregnancy, before, during and after the cesarean section delivery.

Resumo O objetivo do presente artigo consistiu em revisar a literatura em empreendedorismo publicada em língua francesa. Para tanto, estruturou-se uma revisão de escopo dos artigos listados em periódicos relevantes para o contexto francófono da produção científica em empreendedorismo (LASCH e YAMI, 2008): Management International; Revue Française de Gestion; e Revue Internationale PME, com base nos critérios de inclusão e exclusão detalhados e estabelecidos na metodologia do mapeamento. Isso possibilitou a categorização de 166 artigos que abordam a temática, publicados entre 2006 e 2019. Os textos foram analisados e categorizados em torno da distribuição dos artigos entre os periódicos, sua distribuição anual, principais temas de pesquisa, tipo de abordagem, escolhas metodológicas e principais autores do campo. Os resultados indicaram predominância de temáticas específicas na produção francófona, como: fomento ao empreendedorismo, intraempreendedorismo, processo empreendedor e oportunidades, empreendedorismo feminino, finanças, educação empreendedora, perfil e comportamento empreendedor, intenção empreendedora, motivações ao empreendedorismo e empreendedorismo social. Houve predominância de estudos teórico-empíricos, de natureza qualitativa, mas também com espaço significativo para ensaios teóricos sobre o tema. Verificou-se, ainda, a participação de um conjunto de autores centrais que produzem, pesquisam e disseminam resultados de suas investigações sobre empreendedorismo. Com isso, nota-se a constituição de um campo de pesquisas francófono em empreendedorismo plural e multifacetado, que apresenta possibilidades e alternativas teórico-metodológicas para a realização de estudos e investigações sobre o fenômeno empreendedor.
Women in politics: emotions and challenges in complex institutional dynamics

Published: January 2021

Abstract Seminal studies about institutional theory highlighted the focus on cognitive issues in research on institutions. However, during the last few years, a growing body of literature has also been devoted to understanding the role of emotions in institutional dynamics. In one of the classic texts on institutional theory, Scott emphasizes three institutional pillars, the regulatory, the normative, and the cognitive. Researchers point out that there is now a fourth pillar: the role of emotions in institutional theory. This article explores the emotions’ role in institutional dynamics, especially related to women’s political participation in the 2018 Brazilian elections. Three cases of female candidates who showed high performance in pre-election polls, were discussed. The research analyzed the candidates’ interviews and social media, observing their emotions in publications and expressions. Also, emotional expressions of society toward the studied candidates, as well as expressions potentially reflecting the institutional dynamic present in the Brazilian political arrangement, were analyzed. The main results show that during the 2018 Brazilian electoral campaign, in the face of the institutionalization of a masculine environment on the political scenario, the society expressed emotions of hatred and aggression against the three candidates since they violated institutional arrangements about behaviors considered acceptable in the dominant institutional logic. Despite this, two of the three female candidates were elected with the highest number of votes in their states, surpassing their male competitors. The candidate who was not elected obtained a significant number of votes.
From the sacred to the profane: connections between Christian theology and administration
Authors: NEUTGEM ALINE VAN , DELLAGNELO ELOISE HELENA LIVRAMENTO
Published: January 2021

Resumo Este ensaio teórico procurou realizar uma aproximação entre a administração e a teologia cristã. Para tanto, a partir, principalmente, das ideias de Agamben (2008), procurou-se estabelecer relações entre aspectos relativos à teologia cristã e sua ordem trinitária com as características de organizações burocráticas e flexíveis, no intuito de desvelar a sacralidade e a deidade presente nessas organizações, a despeito da ideia de secularização e racionalidade, no sentido weberiano, impetrada às mesmas. A partir dessas relações e da observação de um novo tipo de sacralização nessas organizações que, sem romper com o ideário divino, tornam sagrado o poder econômico, o dinheiro, a técnica e a lógica formal sobre tudo o mais, advoga-se pela profanação do sagrado. Entende-se que essa saída pode se dar por meio das reflexões acerca da inoperosidade e sua relação com a política e a estética, que remetem a uma nova possibilidade de uso do prazer, do desejo e do corpo.
Pandemia de COVID-19 y Estado: ¿Hacia una nueva la configuración administración-Estado

Resumen Como consecuencia de los impactos causados por la pandemia de COVID-19, el Estado ha acelerado reformas ya iniciadas referentes a su alcance, responsabilidades y modelo. Estas también han tenido impacto en la administración pública y en su autonomía y configuración. En escenario deviene de una situación de contingencia, que puede significar un horizonte de posibilidades no imposibles, lo que equivale a un horizonte abierto a cambios. El Estado puede orientarse hacia estructuras y métodos horizontales y participativos, o hacia jerarquías verticales y centralizadas. En esta situación extraordinaria de complejidad, contingencia e incertidumbre, parece necesario cuestionar los conceptos y metodologías teóricas disponibles en las áreas de estudio de la Ciencia Política y la Administración. A partir de estas cuestiones, los ilustramos con la dirección que se está perfilando en el Estado y la administración en Brasil.
Mais uma vez o conceito de gestão social
Authors: TENÓRIO FERNANDO GUILHERME , ARAÚJO EDGILSON TAVARES DE
Published: January 2021

Resumo Este artigo busca repetir, uma vez mais, o conceito de gestão social, que talvez seja um sonho que pode não se realizar, dadas as condições de “temperatura e pressão” sob as quais vivemos na contemporaneidade. Não obstante, a resistência conceitual deve ser o motivo para que possamos reagir ao que consideramos predominante na hodierna área da Administração: a gestão estratégica. Assim, a repetição de um tema que, desde o início dos anos 1990, vem sendo apresentado à academia brasileira é um caminhar em busca de uma qualificação melhor para o conceito central deste texto: a gestão social. Para tanto, apesar de estarmos no início do século XXI, recorremos ao fim do século XVIII, a fim de aproximar o conceito de gestão social dos parâmetros iluministas dessa centúria. Iluminismo ou barbárie? Eis a questão.

Published: January 2021

RESUMO O objetivo do estudo foi verificar a adesão de usuários a grupos de atividade física realizados por fisioterapeutas na atenção básica (AB) e seus fatores associados. Quanto à metodologia, trata-se de estudo transversal, quantitativo. Foi aplicado um questionário semiestruturado e outro de adesão adaptado, que investiga fatores gerais, motivadores e barreiras que podem influenciar na adesão. A amostra foi subdivida em 3 grupos em relação à adesão: 1-30% de frequência em 6 meses baixa adesão, de 31 - 70% média e acima de 71% alta adesão. Os grupos foram comparados pelos testes de Kruskall-Wallis e análise de variância (Anova) e a associação avaliada por regressão logística multinomial. Nos resultados, em relação à adesão, 46,8% da amostra apresentou baixa, 42,2% média e 11% alta adesão entre os 154 participantes, com média etária de 58,98±11,54 anos para fatores gerais, barreiras e motivadores foram diferentes (p<0,05) entre os grupos, e menor relato de fatores gerais de não adesão reduziram a chance de média adesão aos grupos. O maior tempo de participação nos grupos aumentou a chance de média e alta adesão em toda a amostra. Concluímos que o conhecimento dos fatores que influenciam positivamente na adesão, como tempo de participação, disposição e interesse, facilitam o desenvolvimento de estratégias pelos profissionais da AB para sua manutenção. Os resultados mostraram que existem fatores que interferem na adesão aos grupos realizados na AB.

Published: January 2021

RESUMO O movimento de remada representa 51,4% do tempo total de prática do surfe, gerando alta demanda muscular do complexo do ombro. Apesar disso, há uma lacuna na literatura sobre a prevalência de dor e discinese escapular (DE) em surfistas. Este estudo teve o objetivo de avaliar a prevalência de dor no ombro em surfistas amadores do estado do Rio Grande do Sul, no Brasil. Trata-se de estudo observacional descritivo transversal. Foram incluídos 21 homens, com idade entre 18 e 42 anos, que praticassem surfe há no mínimo dois anos. Os desfechos avaliados foram DE estática, DE dinâmica, dor no ombro - através da escala numérica da dor -, comprimento do músculo peitoral menor, e escore no The Western Ontario Shoulder Instability Index. As variáveis contínuas foram apresentadas em média e desvio-padrão. As variáveis categóricas foram expressas em percentual. Associações dos dados foram testadas através do teste qui-quadrado e do teste de correlação de Pearson. A DE estava presente em 71,4% da amostra, tendo uma maior prevalência a discinesia do tipo I (57,1%), e 42,9% apresentaram dor no ombro durante o momento da avaliação. DE foi observada na maioria da população estudada, enquanto dor foi apresentada por pouco menos da metade dos participantes. Embora a DE seja um achado muito prevalente em surfistas amadores, não foi observada correlação com dor e redução da qualidade de vida.

RESUMO Este estudo teve como objetivo avaliar as características da pressão plantar, tipo e sensibilidade do pé em recrutas durante o período do serviço militar obrigatório. Sessenta indivíduos que prestaram o serviço militar obrigatório foram avaliados para pressão plantar (baropodômetro EPS LoranEngineering, Bolonha, Itália) e sensibilidade plantar ao toque superficial (estesiômetro de Semmes-Weinsten) em três momentos distintos: março (linha de base), junho (após 16 semanas de treinamento) e setembro (após 36 semanas de treinamento militar). Foram avaliadas a descarga de peso ântero-posterior e latero-lateral, pressão média, pressão máxima, área de contato do pé, tipologia de pé e sensibilidade plantar. Os dados foram analisados pelo teste do Qui-quadrado, anova de medidas repetidas e pelo teste de Friedman com pos hoc de Bonferroni (p<0,05). Houve aumento na área de contato (p=0,001) e na pressão média de ambos os pés (p<0,001). Quanto a tipologia, aproximadamente 60% dos indivíduos possuíam o pé direito do tipo normal, enquanto o pé esquerdo era do tipo cavo (50,3%); ou seja, mesmos sujeitos apresentaram diferentes tipologias do pé. Em relação a sensibilidade plantar, houve diferença na região do médio pé ao longo do treinamento (p=0,001 no pé dominante e p=0,009 no pé não dominante). Esses resultados demonstram que houve aumento da pressão média e área total de contato do pé, bem como alterações na sensibilidade plantar da região do médio pé ao longo do serviço militar obrigatório.
A Aprendizagem da Dor
Authors: Hermann Nadja
Published: January 2021

Resumo: O interesse pela pandemia extrapola a área de especialistas em saúde pelas repercussões em todos os âmbitos da vida, particularmente na educação. Ao mesmo tempo que traz o estranho, o que é ameaçador, desestabilizando a ordem vigente, a dolorosa experiência mobiliza nossa capacidade de sentir e aprender. Dessa aprendizagem da dor já é possível recolher as primeiras lições da pandemia: o reconhecimento da vulnerabilidade da condição humana, a importância da verdade para enfrentar os problemas e a solidariedade com o outro. O artigo conclui que a aprendizagem e o saber mais amplo decorrentes dessas lições tem uma força transformadora, que se constitui numa espécie de superação, não no sentido de um sentimentalismo ingênuo, mas algo que surge da própria situação dolorosa, pois, como percebe Hölderlin, justamente onde há o perigo cresce a salvação.

Published: January 2021

In order to improve the feature extraction ability of nanofibers, a feature detection method based on non-linear mapping pattern recognition is proposed. The cluster–cluster hybrid molecular reconstruction method is used to deal with the spatial spectrum beamforming of nanofiber features, and the recursive graph analysis method is used to decompose the association rule features of nanofibers to realize the non-linear mapping pattern recognition of nanofiber features. Combined with the related attribute-clustering method, the characteristics of nanofibers are classified and identified to achieve the optimization of nanofiber feature detection. The simulation results show that the method has high accuracy, good performance of pattern recognition of non-linear mapping and good ability of accurate recognition of the crystal structure characteristics of nanofibers.
See how it feels to move: Relationships between movement characteristics and perception of emotions in dance
Authors: Burger Birgitta , Toiviainen Petri
Published: January 2021

Music makes humans move in ways found to relate to, for instance, musical characteristics, personality, or emotional content of the music. In this study, we investigated associations between embodiments of musical emotions and the perception thereof. After collecting motion capture data of dancers moving to emotionally distinct musical stimuli, silent stick-figure animations were rated by a set of observers regarding perceived discrete emotions, while 10 movement features were computationally extracted from the motion capture data. Results indicate kinematic profiles—emotion-specific sets of movement characteristics—that furthermore conform with dimensional models of valence and arousal, suggesting that observers rated the emotions consistently according to distinct movement features prevalent in the animations. Outcomes show commonalities and differences to a previous study that linked these movement features to auditory perception of musical emotion, providing insights into how emotional expression of music-induced movement could be conveyed and understood through auditory and visual channels, respectively.

The article presents two methods of modeling discrete heights of a quasigeoid on a local area of the earth’s surface using a gen-eralized Fourier series. The first method is based on modeling the characteristics of the earth’s gravitational field on a plane and involves the use of a two-dimensional Fourier transform by an orthonormal system of trigonometric functions. The second method consists in the expansion of the quasigeoid heights in a Fourier series by an orthonormal system of spherical functions on a local area of the earth’s surface. The errors of approxima-tion of the obtained discrete values of the quasigeoid heights on the local territory are analyzed. It is shown that with the modern computing technology, the most accurate and technologically simple way to model the quasigeoid heights on local areas is to expand them into a Fourier series by an orthonormal system of spherical functions.
Linguistic Diversity as a Challenge for Street-Level Bureaucrats in a Monolingually-Oriented Organisation
Authors: Scheibelhofer Elisabeth , Holzinger Clara , Draxl Anna-Katharina
Published: January 2021

Migration-induced diversity has led to the global emergence of multilingual life worlds in which language regimes are particularly intertwined with labour markets. Thus, state institutions such as national unemployment services must fulfil a special role in society. In a qualitative research project (2019–2021), we interviewed employees at the Austrian Public Employment Service (AMS) at multiple organisational levels. The results demonstrate diverging and (apparently) contradicting approaches and strategies throughout the organisation concerning the appropriateness of using German exclusively during interactions with clients. This is illustrated along a continuum, ranging from a reflective, critical approach towards linguistic diversity that is at least partly based on ideas promoting the value of multilingualism to frequently encountered notions of the need for monolingualism. Such a framework must be understood by considering the coexistence of diverging ideas and ideologies surrounding multilingualism, as well as a neoliberal working context characterised by new public management and activation policy.
SPECIFIC WOMEN FEARS DURING THE COVID-19 PANDEMIC DEPENDING ON AGE AND HAVING CHILDREN
Authors: Nefedova Tetiana
Published: January 2021

The COVID-19 pandemic has changed the reality of Ukrainian women. Strong movement restriction, social isolation, the disinclination of the health care system have caused stress and intense emotional fear reaction for their lives and future, future and health of their relatives and children. A survey conducted in the UK has shown that men are more likely to get worse symptoms and die from COVID-19. Other researches, which took place in different countries around the world, have shown that women are more worried, anxious and scared about the consequences of the spread of the coronavirus. The article highlights the actual women's fears during the COVID-19 pandemic. It analyses the relationship of women's emotional state to different fears and state/trait anxiety. The aim of the article is to determine the influence of special terms during the COVID-19 pandemic on the intensity of women fears depending on age and having children. Participants (n=140) were asked to complete the Questionnaire of Actual Specific Fears (Ju. Shherbatyh), the Spielberger State-Trait Anxiety Inventory and the visual/verbal analogue fear ‘here and now' scale. The comparative analysis of two age-band groups has shown that there is no significant difference in the intensity of specific fears and anxiety for 25-44 and 45-60 age groups. It was found that women who have children are rather more worried about not getting ill with some disease, have much higher values of fear ‘here and now' and fear of heights as opposed to women who do not have children. The present study shows with what fears were women affected by during quarantine restrictions and the spread of the coronavirus. The article emphasizes the importance of the women psychological state, especially women who have children. It is obvious that additional researches are needed; they should explore specific fears connected with children and COVID-19. Further searches are seen in developing a system of psychological support for people who feel fear during the spread of different diseases and new probable pandemics.
Exploring the Psychosocial Impact of a Mindfulness Workforce Development Program on Instructors of Color: A Qualitative Descriptive Study
Authors: Damian April Joy , McAfee Ciara , Yoo Sera , Mendelson Tamar
Published: January 2021

A growing body of literature supports the use of mindfulness-based practices to increase resilience and reduce emotional and behavioral problems of low-income youth of color who are exposed to chronic trauma. The current study, the first of its kind, addresses existing gaps in the literature by examining the social and emotional effects of mindfulness on instructors of color, a largely understudied population. All trainees (n = 25) in a year-long, mindfulness-based workforce development program in Baltimore were invited to participate in this qualitative descriptive study that involved semistructured interviews regarding the personal emotional impact of participating in the program, as well as possible changes in the subjects’ perceptions of yoga and the potential role of yoga in their communities. We applied a transcript-based analysis approach to the data from the individual interviews and derived themes using the constant comparative method. Twenty-one trainees (84%) participated in semistructured interviews. Participants were between the ages of 18 and 29 and were predominantly male (71.4%) and African-American (85.7%). We identified four key themes related to participating in the program: (1) changes in emotional functioning and self-perception, (2) changes in interactions with others, (3) changes in perception of yoga and mindfulness, and (4) perceived real-world application of yoga and mindfulness. The current study adds to the literature by exploring the public health implications of mindfulness, particularly in addressing effects of chronic trauma in low-income communities of color. The workforce development program also merits further evaluation as a potential model for enabling local and national nonprofit organizations to offer low-income youth and youth of color employment options that enhance resources in trauma-affected communities.
A Region-Specific Ground-Motion Model for Inelastic Spectral Displacement in Northern Italy Considering Spatial Correlation Properties
Authors: Huang Chen , Tarbali Karim , Galasso Carmine
Published: January 2021

The peak inelastic displacement of single-degree-of-freedom bilinear systems (Sdi) is an effective intensity measure linking ground-motion features to the inelastic response and subsequent structural and nonstructural damage of engineered systems. This study develops a region-specific ground-motion model for Sdi considering source, path, and site effects and explicitly accounting for the spatial correlation between intraevent residuals when the model parameters are estimated. The model is developed based on 2427 two-component horizontal ground-motion records from 85 events in northern Italy with magnitudes ranging from 4.0 to 6.4 and source-to-site distances less than 200 km. An exponential stationary and isotropic model is considered to represent the spatial correlation properties of Sdi (after scrutinizing the appropriateness of the underlying assumptions for such a model). Comparisons are performed with existing models in the literature in terms of Sdi estimates, as well as the (spatial correlation) effective range parameter. Two practical applications of the developed model are presented: one on estimating the spatial distribution of Sdi (as an essential ingredient for seismic loss assessments) and one on the engineering validation of region-specific ground-motion simulations. Challenges regarding such validations are also discussed.
Coseismic Fault Slip and Afterslip Associated with the 18 March 2020 M 5.7 Magna, Utah, Earthquake
Authors: Pollitz Fred F. , Wicks Charles W. , Svarc Jerry L.
Published: January 2021

The 2020 Magna, Utah, earthquake produced observable crustal deformation over an ∼100  km2 area around the southeast margin of Great Salt Lake, but it did not produce any surface rupture. To obtain a detailed picture of the fault slip, we combine strong-motion seismic waveforms with Global Positioning System static offsets and Interferometric Synthetic Aperture Radar observations to obtain kinematic and static slip models of the event. We sample the regional seismic wavefield with three-component records from 68 stations of the University of Utah Seismograph Stations network. We find that coseismic slip and afterslip, with predominantly normal slip, distributed on a shallowly west-dipping plane, possibly augmented by afterslip on a steeply northeast-dipping plane, best fits the joint dataset. The west-dipping plane locates near previously inferred sources of interseismic creep at depth. Hence, the earthquake may have occurred on the down-dip extension of the Wasatch fault and activated further slip (afterslip) at shallow depth east of the hypocenter. This inferred afterslip may have driven the vigorous aftershock activity that was concentrated east of the hypocenter.

Published: January 2021

1917 yılında Rusya’da Bolşeviklerin iktidarı ele geçirmesiyle Rusya’da yeni bir dönem başladı. Ekim Devrimi olarak adlandırılan bu dönemden sonra kurulan Sovyetler Birliği, döneminin en etkili güçlerinden biriydi. Lenin öncülüğünde kurulan devlet sosyalist dünya görüşüyle yönetilmekteydi. Dolayısıyla tüm dinlere karşı olumsuz bir bakış açısına sahipti. Bu nedenle devrimin ilk günlerinden itibaren tüm dinlere karşı agresif bir propaganda kampanyası başlatıldı. Ateist bir toplum inşa etmek için yıllarca birçok propaganda yöntem ve tekniği kullanıldı. Ancak 1917-1960 yılları arası dönem Sovyetler Birliği’nde din karşıtı propaganda faaliyetlerinin en etkin yapıldığı dönem olarak ele alınabilir. Bu çalışmada din karşıtı propaganda kavramından yola çıkılarak Sovyetler Birliği’nde 1917-1960 yılları arasında yapılmış olan din karşıtı propaganda çalışmalarına odaklanılmıştır. Sovyetler Birliği’nin dinlere yönelik yaptığı ateist propagandanın ve devletin bu doğrultudaki politikasının ele alındığı çalışmamızda literatür taraması yöntemi kullanılmıştır. Çalışmanın amacı Sovyetler Birliği’nde devlet eliyle yürütülmüş olan propaganda faaliyetlerini, din karşıtı propaganda özelinde incelemektir. Ayrıca yapılan din karşıtı propagandada hangi araçlardan faydalanıldığı ve ateizmi yaymak için ne tür yöntemler kullanıldığını ortaya koymak amaçlanmıştır. Sonuç olarak Sovyetler Birliği’nde 1917 yılından İkinci Dünya Savaşı’na kadar agresif bir din karşıtı propaganda yapıldığı, savaş dönemi ve sonrasında ise bu tutumun terk edildiği görülmüştür. Din karşıtı propagandada ise medya, eğitim ve yüz yüze propaganda araçları etkin bir biçimde kullanılmıştır.

Published: January 2021

Dijital dünyaya çevrimiçi gazeteler ve haber siteleri ile adım atan ulusal gazeteler, sosyal medyanın öneminin giderek artmasıyla birlikte Facebook, Twitter, Youtube gibi farklı sosyal medya mecralardan da haber paylaşmaya başlamıştır. Bu mecralar içerisinde Youtube, sunduğu fırsat ve olanaklar bakımından gazetecilik için giderek daha önemli bir platform hâline gelmektedir. Bu çalışmanın amacı, ulusal gazetelerin Youtube kanallarında paylaştıkları haber videolarını inceleyerek Youtube’u kullanma biçimlerini ortaya koymaktır. Çalışma kapsamında, Youtube’da en çok görüntülenen 5 ulusal gazetenin 1-31 Ağustos 2020 tarihinde Youtube’da paylaştığı toplam 554 video içerik analizi yöntemiyle çözümlenmiştir. Çalışmada; gazeteler tarafından paylaşılan videoların çoğunun televizyon ya da ajansların ürettiği gündem haberlerinden oluştuğu, bu haberlerin, haber kaynağı sesi ile ortam sesi içeren ham görüntüler olduğu ve haber videolarının süresinin 01.00-04.00 dakika aralığında seyrettiği sonuçlarına ulaşılmıştır. Çalışmanın sonuçları ışığında; gazetelerin Youtube’da paylaştığı haber videolarının genel karakteristiğini televizyon ve haber ajanslarından gelen görüntülerin belirlediği, gazetelerin Youtube’u, televizyon ve ajans haberlerini paylaştıkları bir platform olarak konumlandırdıkları, Youtube’a özel içerik üretmede yetersiz kaldıkları ve dolayısıyla Youtube gibi önemli bir mecranın potansiyelini tam olarak kullanamadıkları söylenebilmektedir.

This study aims to analyze the perception of members of the Costa das Dunas Tourist Pole, in the State of Rio Grande do Norte [Brazil], regarding the potential effects of tourism in Protected Natural Áreas, especially in those that are in the process of being implemented. The state parks Mangues do Potengi, in Natal, and Jiqui, in Parnamirim, are studied. The research is exploratory, with a qualitative approach, using for data collection semi-structured interviews, followed by content analysis. It’s noted that the economic aspects are highlighted in their possibility of generating employment and income for the communities. It is also noteworthy that despite tourism being seen as a significant contributor to improving the resident’s quality of life, the involvement of these people in the planning and management of areas, as well as sensitizing visitors, is essential to mitigate undesirable impacts.

This article aims to discuss tourist activity in Brazil from the perspective of uncertainties and fluctuations arising from the country's social, political and economic environment. The article presents data on national and international passenger traffic in Brazil and relates to major events and the occurrence of economic and political crises at the national and international levels. To verify whether crises affect the performance of tourism, a 27-year historical series was prepared based on official statistics from Brazilian government agencies and international organizations such as the WTO. The results presented indicate that, despite the increase in tourist traffic in the first decade of the 21st century, the Brazilian tourism market still underperforms capacity due to the persistent and serious economic and social disparities and political and economic uncertainties. This research offers an alternative perspective regarding the performance of tourist activity in Brazil, by relating the flow of national and international landings to the economic and political turbulences experienced in the period, indicating that contagious systemic crises at an international level affect the Brazilian tourism market less than domestic crises.

Increasingly innovatory techniques are being developed for the manufacturer of coated sheets. Magnetite non-Newtonian fluids have been shown to exhibit stretchable wall slip, which arises due to non-adherence of the non-Newtonian fluid to the boundary. Motivated by the physical nature of the magnetic non-Newtonian fluid in manufacturing transport phenomena, we develop a model to analyze the collective influence of velocity and thermal slips, radiative heat flux effects on fluid and heat transport phenomena in magnetic non-Newtonian fluid flow in a channel with stretchable walls. Governing equations are non-dimensionalized and solved numerically. Grid independence test has been performed and then compared with existing literature in limiting cases. Results are discussed with the aid of graphs for the sway of several physical parameters, Casson parameter, Magnetic parameter, Thermal radiation parameter on fluid velocity, as well as temperature profiles for different cases: No-slip, only first-order slip, and first and second-order slips.

Published: January 2021

In this present works, a generalized approach for the two-phase flow analysis of a natural circulation in hybrid boiler. The model uses the combination of node and loop equations and the Newton Raphson technique for the solution of the set of equations. Loop equations have been developed for each evaporator tube with the unique driving force and pressure drop of the concerned loop. Node equations are mainly developed for common risers and downcomers. A unique connectivity matrix has been used to correlate each branch flow with loop and node equations. The model is validated by a unique indirect method by comparing the actual water level and calculated water level. Experiments have been performed with uniform diameter of tubes in 53 channels circulating loop to find the volume of steam. The model shows good agreement with experimental investigations with a maximum of 3.57% absolute error. The model can be used for the design, analysis, and optimization of the natural circulation network.
