Published: June 2020

BACKGROUND

COVID-19 has not only psychological but also economic and social effects and social media increased the negative effects by disseminating COVID-19 infodemic.

OBJECTIVE

This study aims to investigate impact of the global infection rate on social media posting during the COVID-19 pandemic.

METHODS

The study analyzed 179+ million tweets collected between March 22nd and April 13th, 2020, and global COVID-19 infection rate by using evolutionary clustering analysis.

RESULTS

The results indicated six clusters constructed for each term type, including three-level n-grams (unigrams, bigrams, and trigrams). The frequent occurrences of unigrams (“COVID-19”, “virus”, “government”, “people”, etc.), bigrams (“COVID-19”, “COVID-19 cases”, “times share”, etc.), and trigrams (“COVID 19 crisis”, “things help stop”, “trying times share”). The results demonstrated that the unigram trends on Twitter were up to about two times and 54 times more common than bigram and trigram terms, respectively. Unigrams like “home” or “need” also became important as these terms reflected the main concerns of people during this period. Taken together, the present findings confirm that many tweets were used to broadcast people’s prevalent topics of interest during the COVID-19 pandemic. Further, the results indicated that the number of COVID-19 infections has a significant impact on all clusters, being strong on 86% of clusters and moderate on 16% of clusters. The downward slope in the global infection rate reflected the start of the trending of “social distancing” and “stay at home.”

CONCLUSIONS

These findings suggested that infection rates have a significant impact on social media postings during the COVID-19 pandemic.

Daya Saing, Ekuivalen Tarif, dan Faktor-Faktor yang Memengaruhi Permintaan Ekspor Minyak Sawit Indonesia di Negara OKI
Authors: Nibras Ghina Saarah , Widyastutik Widyastutik
Published: June 2020

Indonesia merupakan negara pengekspor minyak sawit terbesar di dunia. Namun, dalam beberapa tahun terakhir, minyak sawit Indonesia dihadapi oleh beberapa hambatan. Oleh karena itu, Indonesia diharapkan mampu melakukan diversifikasi pasar, salah satunya dengan menjadikan negara anggota Organisasi Kerja sama Islam (OKI) sebagai negara tujuan ekspornya. Penelitian ini bertujuan untuk menganalisis bagaimana daya saing, besarnya ekuivalen tarif, dan faktor-faktor yang memengaruhi permintaan ekspor minyak sawit Indonesia di 28 negara OKI. Metode yang digunakan adalah Export Products Dynamics (EPD) dan regresi data panel. Metode analisis untuk mengestimasi ekuivalen tarif adalah model gravity. Hasil penelitian menunjukkan bahwa minyak sawit Indonesia memiliki daya saing yang cukup kuat pada 15 negara OKI. Sedangkan, minyak sawit Indonesia pada 13 negara OKI lainnya menempati posisi falling star, lost opportunity, dan retreat. Hal ini disebabkan oleh beberapa faktor, di antaranya adanya beberapa negara OKI yang juga merupakan produsen dari minyak sawit, serta adanya kompetitor di negara tujuan. Hasil estimasi menggunakan metode regresi data panel menunjukkan bahwa Produk Domestik Bruto (PDB) per kapita negara importir, jarak ekonomi, harga ekspor, populasi, dan nilai tukar riil berpengaruh signifikan terhadap volume ekspor minyak sawit Indonesia ke negara OKI. Penelitian ini juga menemukan bahwa negara OKI memberlakukan hambatan nontarif terhadap minyak sawit Indonesia walaupun besarannya relatif rendah. Nilai ekuivalen tarif impor tertinggi dikenakan oleh negara Benin sebesar 19,67.
Comparing Means under Heteroscedasticity and Nonnormality: Further Exploring Robust Means Modeling
Authors: Counsell Alyssa , Chalmers Robert Philip , Cribbie Robert A.
Published: June 2020

Comparing the means of independent groups is a concern when the assumptions of normality and variance homogeneity are violated. Robust means modeling (RMM) was proposed as an alternative to ANOVA-type procedures when the assumptions of normality and variance homogeneity are violated. The purpose of this study is to compare the Type I error and power rates of RMM to the trimmed Welch procedure. A Monte Carlo study was used to investigate RMM and the trimmed Welch procedure under several conditions of nonnormality and variance heterogeneity. The results suggest that the trimmed Welch provides a better balance of Type I error control and power than RMM.

El consumo como escenario para la “forja de sí” en las categorías cuerpo y salud: una mirada desde la psicología humanista existencial
Authors: Ortiz Pabón Norela
Published: June 2020

Este artículo plantea una reflexión teórica sobre los valores existenciales en el consumo como fenómeno social. Se definió como marco teórico la psicología humanista existencial y se delimitó el análisis al cuerpo y la salud, categorías de interés para la psicología, el mercadeo y la publicidad. Se acudió a la investigación cualitativa con una revisión bibliográfica de tipo hermenéutico. Estas categorías remitieron a las nociones de “cuidado de sí” y de “forja de sí”, las cuales son necesarias para que el hombre se oriente, si es su elección, a una “buena vida”. Se encontró como línea temática vinculante el límite como inherente a la libertad y a la responsabilidad. El estudio finalmente permitió comprender que la “forja de sí” y el “cuidado de sí” están enmarcados dentro de ese ejercicio del límite, la libertad y la responsabilidad. Si bien en las categorías cuerpo y salud el hombre de hoy tiene prácticas para “cuidar de sí”, estas están atravesadas por las dinámicas de mercado que lo orientan hacia lograr un cuerpo y una salud idealizados, medicalizados y funcionales para el trabajo y la productividad, así como para experiencias de goce hedónico que lo esclavizan y no necesariamente lo conducen a una “forja de sí”.
As diversas fronteiras da América Meridional: alianças e inimizades com infiéis no século XVIII
Authors: Felippe Guilherme Galhegos , Santos Maria Cristina dos
Published: June 2020

A fronteira faz parte da constituição espacial e política da América Meridional. Nessa região, os conflitos gerados pela disputa e controle dos territórios tendem a se acirrar à medida que avança o projeto colonial, fazendo com que surjam também, nas fronteiras, outras interfaces culturais. A categoria de índios infiéis, por oposição aos indígenas cristianizados, é recorrente na documentação colonial, convertendo-se numa ambígua categoria identificadora dos primeiros. O propósito desse texto é discutir as possibilidades de alianças e inimizades a partir da vinculação que se estabelece entre fronteira e infiel, na primeira quinzena do século XVIII.
A estratégia político-administrativa do imperador Teodósio II na convocação de Nestório para o episcopado de Constantinopla (428 d.C.)
Authors: De Figueiredo Daniel
Published: June 2020

O objetivo desse artigo é analisar a estratégia político-administrativa do imperador Teodósio II (408-450 d.C.) na convocação do bispo Nestório para o episcopado de Constantinopla, em 428 d.C. Esse acontecimento deu início à Controvérsia Nestoriana, conflito teológico que emergiu na hierarquia eclesiástica do Império Romano do Oriente e buscava estabelecer uma ortodoxia em relação ao modo como se deu a interação entre as naturezas humana e divina no Cristo encarnado. Ao se perceber que as facções formadasna defesa da união das naturezas, advogada pelo bispo Cirilo de Alexandria, e separação delas, defendida por Nestório de Constantinopla, contemplavam a presença de funcionários da administração imperial na disputa, indicaremos que o sentido da convocação de Nestório para o episcopado de Constantinopla,por Teodósio II, esteve relacionado não apenas ao estabelecimento de projeto de unidade religiosa, mas se inseria, também, no complexo jogo político-administrativo que abarcava a acomodação de interesses e o contrabalanceamento de poderes com as aristocracias de funcionários que contribuíam para legitimar a unidade imperial.
Reinos e notícias reluzentes nos meandros do Rio da Prata e da cordilheira andina: a iconografia cartográfica francesa em meados do século XVI

Published: June 2020

No presente estudo, analisamos mapas franceses produzidos entre 1546 e 1555, buscando observar a maneira como representavam, cartográfica/iconograficamente, os meandros da região do Rio da Prata e da Cordilheira Andina. O foco da atenção incide sobre imagens alusivas às minas de ouro e prata e aos supostos reinos indígenas ocultos, porém, vagamente noticiados por conquistadores espanhóis. Asrepresentações dos indígenas, os anseios coloniais ultramarinos e o caráter de instigação política promovida pelas cartas geográficas francesas são os temas que constituem nosso âmbito de interesse. Nosso diálogo epistemológico envolve áreas afins como a Antropologia, História da Arte e da Cartografia.
Competencias digitales docentes: un acercamiento inicial
Authors: Castro-Granados Alejandra , Artavia-Díaz  Karla Yanitzia
Published: June 2020

El estudio tiene un alcance de tipo descriptivo, no experimental, bajo el paradigma cualitativo ya que realiza un análisis documental acerca de las competencias digitales docentes que posteriormente permita el desarrollo de nuevas investigaciones a partir de esta materia. Para ello, se llevó a cabo una búsqueda y selección de documentos que permitió establecer los antecedentes sobre el tema desde los países anglosajones, algunos europeos y de América Latina hasta llegar al ámbito nacional. Seguidamente, se definen la alfabetización digital, las habilidades y competencias (entre ellas la digital), para finalizar con el rol docente y las Tecnologías de Información y Comunicación (TIC) como parte del eje central de esta indagación; ya que se puede concluir que es un arduo papel el que desempeña la educación y por consiguiente el rol docente, como el encargado de planificar y ejecutar las acciones que formen a un ciudadano integral, crítico y competente en los diferentes saberes. De ahí la relevancia de conocer sobre la temática y a partir de ella proponer requerimientos de referencia contextualizados que de forma paralela impulsen la formación del profesorado para lograr los objetivos comunes del país y de la región en el mercado laboral.

La incorporación de las actividades lúdicas como herramienta de aprendizaje en el proceso de enseñanza aprendizaje se utilizó en tres asignaturas durante el año 2018. Con el objetivo de conocer la percepción de los estudiantes en el uso de las actividades lúdicas como estrategia de enseñanza–aprendizaje en los entornos virtuales.  Es la primera vez que se utiliza en la Cátedra Producción Sustentable y a nivel de la carrera de Manejo de Recursos Naturales. La utilización de estas actividades proporciona un refrescamiento en la forma de aprender del estudiante, además, generó una sensación de satisfacción al realizarlas y ganar la mayor cantidad de puntaje o en sentido opuesto, de que deben repasar más la materia si no le fue tan bien. De los estudiantes a 83% les pareció entretenida, no obstante, para un grupo de estudiantes fue tenso.  La primera vez que el estudiante a nivel de bachillerato se enfrentó a este tipo de actividad, se sintieron poco cómodos, sin embargo, el siguiente cuatrimestre se enfrentaron a otras actividades similares y su aceptación fue mucho mejor.

Published: June 2020

El camino recorrido por las editoriales universitarias en América Latina y el Caribe se ha consolidado, al igual que las organizaciones que impulsan su desarrollo y el de la producción didáctica; por tanto, en este texto se versa sobre el recorrido, sus aportes y la teoría que lo acompaña. Específicamente, la investigación se enfocó en contrastar el proceso de producción de unidades didácticas generadas por el Programa de Producción de Materiales Didácticos (Promade) de la Universidad Estatal a Distancia de Costa Rica (UNED), con el marco Unesco como referente teórico para la elaboración de los materiales didácticos. Los resultados indican que el proceso de Promade mantiene clara concordancia con el referente, además, se destacan sus aportes de producción de materiales a lo largo de los últimos 16 años. Se concluye que el proceso de producción de Promade cumple un ciclo maduro, cuya característica le permite aplicar estándares de calidad que podrían ser trazados. También se identifican oportunidades de mejora, entre ellas el mercadeo y la comercialización de los productos.

Crustaceans (Decapoda & Stomatopoda) from Golfo Dulce (Pacific, Costa Rica) in the collection of the Museum of Zoology, University of Costa Rica
Authors: Vargas Castillo Rita , Vargas-Zamora José A.
Published: June 2020

Introduction: The availability of recently updated lists of species from a particular area is an important first step to evaluate changes in species composition and abundance. Golfo Dulce is a fjord-like embayment with relatively pristine shores and relatively deep waters (200m) that have been sampled occasionally for crustaceans. Methods: In this study the all species from Golfo Dulce deposited in the collection of the University of Costa Rica Museum of Zoology were listed and scientific names were updated. The MZUCR catalog number, station, substrate type, and year or collection were included for each species. Results: A total of 106 species were listed. Neogonodactylus zacae was present in four of the 19 stations represented in the collections for Golfo Dulce. Nine species were present in three stations, 19 in two stations and the remaining 77 in one station each. The families with most species were Ocypodidae y Palaemonidae (7) and Porcellanidae (14). Conclusions: Is necessary to improve our knowledge of the decapods and stomatopods fauna from Golfo Dulce through further samplings. Intertidal sites such as Golfito and Rincón bays have been poorly sampled as well as intertidal and subtidal environment from the western and eastern shores. However, the fauna is relatively rich when it is related to the area of Golfo Dulce (750km2) and is indicative of a relatively undisturbed environment. Updated management policies are urgently needed and this list of species is a step towards this goal.

Authors: Leão Aline Aparecida de Souza , Silva Marcela Flores da , Lanza Leni Boghossiam
Published: June 2020

Introdução: A segurança do paciente é um tema importante que deve ser sempre preocupação dos profissionais de saúde e uma das metas da prestação do cuidado. A prevenção das lesões por pressão (LPP) é considerada item imprescindível nesse contexto. Sendo assim, a profilaxia das LPP é compromisso ético e legal da equipe enfermagem. Método: Trata-se de estudo exploratório, descritivo e de modalidade qualiquantitativa. Foi realizado em duas instituições hospitalares, uma pública e outra privada, com 34 profissionais de enfermagem dos períodos noturno e diurno das clínicas médica e cirúrgica de ambas e da unidade de terapia intensiva. Utilizaram-se formulários com duas partes: a primeira para caracterização dos participantes; a segunda com perguntas abertas e de múltipla escolha. As respostas das perguntas abertas foram organizadas tematicamente, e os dados sociodemográficos e as respostas às perguntas de múltipla escolha foram organizados segundo a frequência. Resultados: Cerca de 45% dos técnicos e 50% dos auxiliares de enfermagem apresentam carência no conhecimento das LPP, reafirmando as noções limitadas sobre o Programa Nacional de Segurança do Paciente. Todos os enfermeiros, 73,33% dos técnicos e 37,5% dos auxiliares de enfermagem reconheceram que nem todas as medidas profiláticas são úteis nas situações de risco para as lesões, evidenciando o pouco comprometimento da equipe na aplicação integral dessas medidas. Considerações finais: A educação permanente em saúde é o meio mais eficaz a ser desenvolvido pela equipe de enfermagem, estimulando atuação crítica, reflexiva, propositiva, compromissada e tecnicamente eficiente, o que auxilia na efetivação das medidas de segurança do paciente.
Economic Activities of African Migrants in Major EU Countries: New Approaches
Authors: Kuznetsov A. V.
Published: June 2020

The growing interest in migration issues in the EU has not affected the analysis of African migrants. The focus is on social and political issues, while the economic issues studied are primarily related to the assessment of the reasons for the arrival of Africans in the EU, the trajectory of their movement, as well as the scale of remittances to their homeland and the conditions for their return back to Africa. The article focuses on the main features of African migrants’ economic activity in the EU. Instead of the traditional consideration of only one or several diasporas in a single country or a generalized analysis of the entire EU, we compare the specifics of immigrants from different African countries in the 4 largest EU member states (including the UK, which left the integration project in 2020). Our article begins with a review of studies that contain information on the economic activities of migrants from African countries. Then, based on data from Eurostat and national statistics from Germany, France, Italy and the UK, the role of people from Africa in these countries population is shown. The reasons for the differences between these four countries in the dynamics and structure of immigration from Africa are explained. Statistics of refugees, naturalized persons over the past 10 years, foreign citizens and residents with migration past are considered. France is the leader in the number of migrants, mainly due to people from French-speaking countries of North and West Africa. Italy stands out because it is targeted by many illegal migrant routes due to its geographical proximity to this region. The UK has become a target mainly for residents of former British colonies who are quite successful in naturalization in the United Kingdom (therefore, there are as many Africans without local passports in the UK as in Germany – 0.6 million). Further, it is shown that the key factor for taking a particular economic position in society is the status of migrants, their education also plays an important role (although Africans often work in places where a lower level of qualification is required than they have), as well as language barriers. There are big gender differences. At the end of the article we make conclusions about the problems of African migrants’ adaptation, although the EU countries cannot refuse to employ migrants in unattractive jobs in any case.
Global Cities as the Hubs of New Transnational Actors
Authors: Sluka N. A. , Karyakin V. V. , Kolyasev E. F.
Published: June 2020

In the context of the world development paradigm shift and the transition to a network structure, so-called new transnational actors are beginning to play an increasing role in global governance processes, their activity is constantly growing and their composition is expanding. In the economic sphere their core is made up of transnational corporations (TNC), in the political sphere  – of international organizations of different profiles and status. Placing their headquarters in cities, such structures, together with the institutions of traditional subjects of international relations, largely determine both the set of command and control functions over urban agglomerations, their competitiveness, sustainability of development and the variability of the configuration of the General framework of “centers of power” operating on the world stage. Their influence growth in the context of desovereignization process development means the approximation of the historical transition in the spatial organization of the international community from its traditional “countries-nations” model to the “archipelago of cities”, which is a set of centers of different rank and functional profile, closely interacting on a global scale.

The global cities concept, which emerged in the 1990s, is aimed at revealing this phenomenon. The explanatory part of this concept is based on the superposition of network structures of global firms highly specialized business services in global cities. The article discusses the main directions in modern research of global cities, argues for the need for a qualitative update of existing approaches, and the importance of new transnational actors in their formation. An assessment of the dynamics and localization of the headquarters of the world’s leading TNCs and international organizations is given. The revealed asymmetry in their placement refutes the hypothesis that global cities are equally attractive. Based on the rating and grouping of centers, several types of hubs of new transnational actors were identified, including complex ones headed by “hegemonic cities” (New York, London, Paris), and specialized ones of various ranks – geoeconomic and geopolitical. Given the relevance and significance of the phenomenon of new transnational actors based in urban agglomerations, it is assumed that a productive study of the features of their formation, composition, specialization, placement and interaction mechanisms can become the subject field of a new scientific problem area at the intersection of a number of disciplines  – geopolitical urbanism, which can make a significant contribution to the study of the contours of future global transformations.
Cyber crimes in the banking sector: Case study of Vietnam
Authors: Tam LE Thanh , Chau Nguyen Minh , Mai Pham Ngoc , Phuong Ngo Ha , Tran Vu Khanh Huyen
Published: June 2020

The technological revolution 4.0 brings great opportunities, but also cybercrimes to economic sectors, especially to banks. Using secondary data and survey results of 305 bank clients, the main findings of this paper are: (i) there are several types of cybercrimes in the banking sector; (ii) Vietnam is one of the top countries worldwide having hackers and being attacked by hackers, especially the banking sector. Three most common attacks are skimming, hacking and phishing. Number of cybercrime attacks in Vietnam are increasing rapidly over years; (iii) Vietnamese customers are very vulnerable to cybercrime in banking, as more than 58% seem to hear about cybercrimes, and how banks provide services to let them know about their transactions. However, more than 50% do not have any deep knowledge or any measures for preventing cybercrime; (iii) Customers believe in banks, but do not think that banks can deal with cybercrime issues well. They still feel traditional transactions are more secure than e-transactions; (iv) the reasons for high cybercrimes come from commercial banks (low management and human capacity), supporting environment (inadequate), legal framework (not yet strong and strict enough on cybercrimes), and clients (low level of financial literacy). Therefore, several solutions should be carried out, from all stakeholders, for improving the cybersecurity in Vietnamese banks.
LABORATORY EVALUATION OF BENGKULU ISOLATES OF Beauveria bassiana AND Metarhizium anisopliae AGAINST COFFEE BERRY BORER, Hyphotenemus hampei, USING SPRAYING METHOD

Published: June 2020

Laboratory Evaluation of Local Isolates of Beauveria bassiana and Metarhizium anisopliae against Coffee Berry Borer, Hyphotenemus hampei, using spryaing method. Beauveria bassiana Bals (Vuillemin) and Metarhizium anisopliae (Metschnikoff) Sorokin are two species of fungi that have been studied widely and used as biological control of various insect pests, including coffee berry borer (CBB), Hyphotenemus hampei Ferrari. Laboratory studies were done in June – July 2017, to evaluate local isolates of both fungi species against CBB, the most destructive insect pest of coffee worldwide, including in Indonesia. B. bassiana was isolated from dead sweet potato weevil (Cylas formicarius) and green stink bug (Nezara viridula), and from soil. M. anisopliae was isolated from soil. The pure cultures of the fungi were mass-cultured on corn based media. The conidia harvested from 4 week colonies was hand sprayed directly upon CBB adults (females) and damaged coffee berry at the concentration of 109 ml-1. In additions, the conidia of B. bassiana isolated from C. formicarius alone was diluted to 106- 109 ml-1 and applied to damaged coffee berry. The results showed that when the conidia were applied directly upon the insects, the mortality of beetle were higher in B. bassiana than in M. anisopliae treatments. Pooled data indicated that B. bassiana isolated from death insects significantly caused higher mortality than did M. anisopliae isolated from soil. Beetle mortality was 76.7 and 80.0% for B. basiana, and 60.3 and 60% for M. anysopliae treatments. Application upon damage coffee berry indicated much lower mortality. Application of higher concentration upon damaged coffee berry resulted higher mortality, but data are not consistent. The mortality of CBB larvae was much less and negligible even at the highest conidia concentration.

Published: June 2020

Metabolic impairments could be seen at any point in human development. Although emphasis has been placed on older adults but it could be encountered in any age brackets. The aim of this study was to compare prevalence rates using different definitions of Metabolic syndrome (MetS) among students of Faculty of Health Sciences and Technology (FHST) in Ebonyi State University (EBSU), Abakaliki. Â This was a cross-sectional study involving 80 students (28 male students and 52 female students) recruited from among students of FHST in EBSU, Abakaliki, Ebonyi State, Nigeria. MetS was defined in three different ways [by International Diabetes Federation (IDF), National Cholesterol Education Programâ€”Adult Treatment Panel III (NCEP-ATPIII), or World Health Organization (WHO) criteria]. Prevalence was found to be 6.3%, 2.5% and 7.5% using NCEP-ATP III, WHO, and IDF definitions respectively.Â  The most common MetS components among female students using the NCEP-ATP III criteria were high blood pressure (5.8%) and abdominal obesity (5.8%), whilst low HDL-C concentrations, high blood pressure and abdominal obesity were most common among male students (7.1 % for each component mentioned). According to WHO, abdominal obesity (7.1%) and hyperglycaemia (7.1%) were the most common MetS components among male students. The most common MetS components among participants using the IDF criteria were abdominal obesity and high blood pressure. While some participants did not meet the MetS criteria of the NCEP-ATP III, WHO and IDF criteria (50%), many had one (30%) or two (13.8%) components and may be at risk of developing the syndrome in the future. The mean values of the risk factorsÂ  used as criteria for the diagnosis of MetS were relatively normal in the study population thereby masking the presence of MetS, thus showing that the prevalence of MetS may gradually increase undetected unless individual members of the study population are subjected to laboratory investigation using different criteria for diagnosis of MetS. Therefore, traditional risk factors might be late markers for diagnosis of MetS since findings from this study showed that MetS was only detected in participants that already had it.

Forecasting future energy demand values is of paramount importance for proper resource planning. This paper examines energy outlook for the coming decade in CÃ´te dâ€™Ivoire presented as a business as usual scenario. We, therefore, build a forecasting model using the Autoregressive Integrated Moving Average (ARIMA) to estimate primary energy demand and energy demand by fuels. The results indicate that energy demand will increase steadily within the forecasted period (2017-2030). However, the annual growth rate of each fuel,, including the primary energy demand item, will first rise from the year 1990 to the year 2016 and then decrease within the forecasted period except hydropower that will experience a steady increase from 1990 to 2030. Furthermore, it is noticed that the energy structure of the country will still be biofuels (fuelwood and charcoal) intensive with a significant presence of conventional sources of energy. Based on these findings, we propose some policy recommendations.

Desenvolvimento regional do sudeste do Pará
Authors: Alves Erisvaldo de Oliveira , Oliveira Nilton Marques de
Published: June 2020

Este artigo examinou o processo de desenvolvimento regional do sudeste do Pará, identificado como a parte do Estado pertencente à região de referência denominada Centro Norte do Brasil. A metodologia utilizada foi o Índice de Desenvolvimento Regional e, como recorte temporal, os anos de 2000 a 2010. Os principais resultados apontam para uma região onde o município de Marabá se destaca como lugar central, mas Parauapebas e Tucuruí também têm destaque, de formas e intensidades diferentes. De modo geral, todos os municípios avançaram no conjunto dos indicadores. A região tem aptidão para crescimento sustentado em uma economia de base exportadora, necessitando investir em agregação de valor ao produto regional, fixar os ganhos e internalizar seus benefícios. Do ponto de vista do capital social, ocorreram melhoras no período analisado, havendo, porém, espaço para o fortalecimento do empoderamento da sociedade organizada.

Produção de soja, desigualdades no campo e mudanças climáticas na região do Matopiba
Authors: Santos João Francisco Severo
Published: June 2020

O objetivo deste estudo foi analisar a relação entre produção de soja e desigualdade fundiária dos municípios e de renda dos estabelecimentos agropecuários da região do Matopiba, no período entre 2006 e 2017. Também de verificar se a expansão das áreas de sojicultura está associada as mudanças climáticas locais no período de 1999 a 2018. Para isso, os indicadores econômicos e fundiários dos municípios produtores - MPS e não produtores de soja - NPS foram comparados. Além disso, foi realizada a análise de correlação entre variáveis climáticas e a área destinada à soja. Os resultados indicam que o crescimento econômico dos MPS não reduz as desigualdades. Os MPS há mais de 30 anos são os que apresentaram maior crescimento econômico e concentração de renda, porém, sem alterações significativas na concentração fundiária. Os NPS apresentaram queda da desigualdade fundiária e de renda, embora sua renda total e suas áreas produtivas sejam menores que as dos MPS.  O tamanho das áreas de cultivo dessa conmoditie apresentou significativa relação com os efeitos indesejados o clima, como elevação das temperaturas médias e redução do volume de chuvas. Conclui-se que a sojicultura induz a um tipo de crescimento econômico que destoa dos princípios do desenvolvimento sustentável.

«Dios ha muerto» y «¿Dioniso contra el crucificado?» Sobre la crítica de Nietzsche a la religión y al cristianismo
Authors: Sommer Andreas Urs
Published: June 2020

El artículo confronta los eslóganes bien conocidos de ‘Dios ha muerto’ y ‘Dionisos contra el cruciﬁcado’ y pregunta por qué trata de nuevo del problema del Cristianismo (particularmente en El Anticristo) , aunque él ya había establecido en general su rechazo del teísmo a comienzos de 1880. El artículo muestra  que no era suﬁciente para la transvaloración proyectada de Nietzsche quedarse dentro de los límites de crítica general de religión. En cambio, la religión ‘positiva’ concreta tenía que ser reemplazada. Esto era una nueva manera del escepticismo experimental de Nietzsche
Влияние ультразвукового излучения на время всплытия микропузырьков воздуха

Published: June 2020

Представлены результаты экспериментального исследования влияния ультразвукового излучения, генерируемого дисковым пьезокерамическим элементом ЦТС-19, на время всплытия микропузырьков, выделяемых из пересыщенного воздухом водного раствора. Показано, что под действием ультразвука происходит объединение пузырьков в комплексы, что увеличивает скорость их всплытия. Зависимость времени всплытия от частоты излучения носит сложный характер, применение ультразвука с частотой 160 кГц может снизить время всплытия с 39,9 до 13,5 с. Результаты работы могут быть использованы для увеличения производительности установок очистки сточных вод методом напорной флотации.
The paper presents the results of an experimental study of the effect of ultrasonic radiation generated by a piezoelectric ceramic disk on the ascent time of microbubbles released from an
aqueous solution saturated with air. It was shown that being irradiated by ultrasound, the bubbles
combine into complexes, which increases the rate of their ascent. Dependency of the ascent time on
the frequency of ultrasonic radiation is of a complex nature; however, the use of ultrasound with a
frequency of 160 kHz can reduce the ascent time from 39.9 to 13.5 s. The results can be used to increase the productivity of wastewater treatment plants by pressure flotation.
