As alterações causadas pela ação do homem ao meio ambiente podem influenciar a disponibilidade de água em bacias hidrográficas, e mensurar os impactos causados por essa ação é imprescindível para a tomada de decisões por órgãos gestores. Dessa forma, o objetivo deste estudo foi realizar a calibração e validação do modelo MGB-IPH para simular o comportamento da vazão na bacia hidrográfica do rio Pardo em diferentes cenários de uso e ocupação do solo. Para isso, foram usadas informações de uso e ocupação do solo que revelaram que a bacia hidrográfica em estudo teve uma redução em sua área de floresta e aumento das áreas dedicadas às atividades agropecuárias, entre os anos de 2001 e 2016. Com essas informações acerca da bacia e com os dados climáticos e os tipos de solos disponíveis, foram realizadas a calibração e a validação do modelo, que teve seus desempenhos verificados. As mudanças nas vazões mensais médias, totais, máximas e mínimas simuladas pelos diferentes cenários foram comparadas por meio de teste de média para amostras dependentes e avaliação das vazões anuais máximas, médias e mínimas dos valores testados. O MGB-IPH foi validado de forma satisfatória para a estação 53880000 da Agência Nacional de Águas, tendo problemas de subestimativa de picos de vazões máximas, porém conseguindo representar adequadamente os dados observados em termos da sazonalidade das vazões, da diferenciação de anos mais úmidos e anos mais secos, e dos picos de cheias de média e pequena intensidade. O modelo foi sensível ao identificar o impacto das mudanças do uso e ocupação do solo nas vazões simuladas para a bacia hidrográfica do rio Pardo, com o cenário de 2016 apresentando maiores valores de vazões mensais médias, totais, máximas e mínimas que as encontradas no cenário de 2001.

O trabalho objetivou acompanhar a colonização da comunidade da fauna edáfica, como indicador de qualidade de ambiente, após a revegetação de áreas alteradas pela atividade de mineração de bauxita, em Porto Trombetas, Pará. As amostragens foram realizadas nos anos 2000, 2002, 2003, 2004 e 2008 em plantios de diferentes idades, e com diferentes arranjos de espécies, majoritariamente nativas do bioma, implantadas sobre subsolo com e sem adição de solo superficial. Os organismos da fauna edáfica foram capturados em armadilhas do tipo pitfall e triados no laboratório. Os parâmetros usados para avaliação foram a abundância, a riqueza, os índices de diversidade de Shannon e Equabilidade de Pielou e o padrão de colonização dos indivíduos da fauna do solo. De modo geral, em todos os plantios sobre o estéril, os grupos que apareceram em maior abundância foram Collembola, Formicidae e Coleoptera. A idade do plantio e a adição de solo superficial foram fatores determinantes na recomposição da comunidade edáfica, que se mostrou mais intensa nos plantios mais antigos. Nessas áreas, o desenvolvimento da vegetação levou à maior colonização e à melhor estruturação da comunidade de fauna edáfica, aumentando sua diversidade e o restabelecimento de processos ecológicos.

Published: April 2021

Blastopsylla occidentalis Taylor,1985 (Hemiptera: Aphalaridae) é um psilídeo que tem como hospedeiro o eucalipto, originário da Austrália, foi introduzido no Brasil em meados da década de 1990. Devido à escassez de informações a respeito da biologia desse inseto, este trabalho teve como objetivo conhecer o efeito da temperatura no desenvolvimento e reprodução do psilídeo sob condições de laboratório. O experimento foi realizado entre 2018 e 2019, em câmaras climatizadas reguladas em cinco temperaturas (15, 20, 25, 30 e 35°C). Os parâmetros observados nessa etapa do experimento foram: período de desenvolvimento dos ovos (número de dias, da postura até a eclosão); taxa de eclosão de imaturos; desenvolvimento de imaturos; taxa de emergência de adultos; longevidade, o período (em dia) de postura até a morte dos adultos da primeira geração (F1). Como resultado obteve-se o ciclo completo nas temperaturas 20, 25 e 30oC, com duração média de 32,78, 27,76 e 28,44 dias, respectivamente. Para a geração F1, não foram observadas postura na temperatura 30ºC, enquanto em 20 e 25ºC, a fecundidade média das fêmeas foi de 19,04 e 26,40, respectivamente. A duração média do período de incubação de ovos foi de 6,70 (20ºC) e 5,59 dias (25ºC). Portanto, infere-se que as temperaturas 15 e 35ºC são limitantes para o desenvolvimento do inseto, pois, durante o estudo, os imaturos de Blastopsylla occidentalis não completaram o ciclo de desenvolvimento. A faixa de temperatura ótima para o desenvolvimento e reprodução foi entre 20 e 25ºC, sendo que em 25ºC foi a temperatura em que o inseto apresentou menor mortalidade em todas as fases, menor tempo de desenvolvimento e maior número médio de ovos/dias. Espera-se que esses resultados sirvam para conduzir estudos para a aplicação de técnicas de manejo para eventual controle da espécie.

Published: April 2021

O artigo tem como objetivo analisar de que forma o Manual Escolar, como recurso material central do processo educativo, se tem adaptado às alterações curriculares introduzidas em Portugal com a publicação de nova legislação relacionada com as aprendizagens escolares e a formação integral dos/as alunos/as ao terminar a escolaridade obrigatória. Procurou-se conhecer a visão dos professores e professoras sobre a forma como as alterações curriculares foram (ou não) acompanhadas por uma reformulação dos manuais escolares no sentido de responder aos novos desafios colocados a docentes e discentes. A recolha de dados sobre a perceção dos/das docentes foi realizada mediante a utilização de inquéritos por questionário. Os resultados preliminares apontam para a existência de algum desfasamento entre as novas indicações curriculares e os manuais escolares que suportam o trabalho de docentes e discentes. Com efeito, a nova legislação relacionada com as aprendizagens escolares e a formação integral dos discentes não inclui uma nova visão e uso do manual escolar no sentido de responder às novas exigências do sistema educativo nacional. Apresentam-se algumas recomendações com base nas necessidades detetadas pelos/as docentes.
Estado y educación en tiempos de la crisis neoliberal: Venezuela, un espacio de resistencia
Authors: Ruiz Samuel Hilcías Carvajal
Published: April 2021

El presente ensayo tiene como eje reflexivo la relación entre el Estado y la educación a partir de la problematización de las políticas públicas bajo la impronta neoliberal, la crisis por la cual atraviesa y sus implicaciones generales y específicas, en un escenario concreto como es el contexto venezolano. Para este propósito se indaga sobre la situación del sistema – mundo gobernado por una suerte de caos ordenado en el que lo ha sumido la hegemonía cultural y material del neoliberalismo. Esta crisis ha tenido impactos asimétricamente adversos en la región y, de manera específica, en Venezuela; donde pese a las medidas coercitivas unilaterales de bloqueo impuesta por la administración Obama e incrementadas por la actual gestión de Donald Trump, más la sumisión colonizada de la mayoría de los países que están bajo la órbita de la Organización de Estados Americanos (OEA) a la política injerencista de Washington comprometido en la política de “cambio de régimen”, el país ha mantenido el proyecto de transformación estructural de la sociedad venezolana, con la Constitución de la República Bolivariana de Venezuela y el Plan de la Patria (2019 – 2025) como referentes teleológicos y programáticos del proyecto de políticas públicas garantista de derechos económicos, políticos, sociales y culturales, entre ellos el de la educación.

Published: April 2021

Quantification of sediment yield is important in determining the impacts of erosion processes on the watersheds. One way to determine their values is through the construction of the sediment-transport curve. The objective of this work is to calculate the sediment yield and to analyze the time variation in a hydrosedimentological monitoring station by designing and adjusting the sediment-transport curve, testing the deviations for curve fitting with a single section and divided into two sections. The 87380000 station is located in the municipality of Campo Bom (RS), operated by CPRM. The sediment-transport curve was built in a single section and divided into two sections. In addition, the Excel solver was used to set the curve to the data. Comparison of the relative standard deviation calculated for each curve allowed a comparison of the results. The sediment-transport curve. that best represented the data set was the one constructed with the split in two sections adjusted by the solver.

It has been of great interest, both on the part of researchers and investors, to define negotiation rules that make it possible to capture the dynamics of the financial markets. This article presents a negotiation model among financial agents, based on the stock buying and selling process, that form a financial market. For the adaptation of economic agents to the market, a Particle Swarm Optimization (PSO) algorithm was implemented to optimize trading rules between agents aiming at maximizing gains in the market. Times series of artificial markets and real Bovespa brazillian market, descripted by the index Bovespa, were used in the computational simulations. Through the simulations, the dynamics of the interaction of buying and selling between financial agents was explored. The results show that there is a dependence on the gains of the agents in the markets in relation to the trading strategies adopted. On the other hand, in the low markets this dependence was not observed, since no statistically significant differences were found for the amount of wealth accumulated among the market participants. For the Bovespa market, from the sell and purchase thresholds of the trades carried out, the agents that have the best strategies in the negotiations were identified.

The digital roots S* (x), of a n positive integer is the digit 0 ≤ b ≤ 9 obtained through an iterative digit sum process, where each iteration is obtained from the previous result so that only the b digit remains. For example, the iterated sum of 999999 is 9 because 9 + 9 + 9 + 9 + 9 + 9 = 54 and 5 + 4 = 9. The sum of the digits of a positive integer, and even the digital roots, is a recurring subject in mathematical competitions and has been addressed in several papers, for example in Ghannam (2012), Ismirli (2014) or Lin (2016). Here we extend the application Sast to a positive rational number x with finite decimal representation. We highlight the following result: given a rational number x, with finite decimal representation, and the sum of its digits is 9, so when divided x by powers of 2, the number resulting also has the sum of its digits 9. Fact that also occurs when the x number is divided by powers of 5. Similar results were found when the x digit sum is 3 or 6.
The relation between gender and differences in emotional intelligence of female managers in modern rural tourism
Authors: Čolović Milica , Nikić Gordana , Stamatović Milan
Published: April 2021

The main goal of this research is to examine the relation between gender and differences in affective attachment, emotional intelligence and self-esteem among students population. The scales for self-assessment of emotional intelligence, affective attachment and self-esteem were used in the current research. The sample consisted of 231 respondents, students of tourism and hospitality management, 71 males and 160 females. Considering that our sample is not representative, because there is a large disproportion in the number of male and female respondents, and that distribution of scores on measured variables deviates from normal, we used nonparametric techniques: Mann-Whitney U test and Kruskal-Walis oneway analysis of variance. The results show that female students have more pronounced emotional intelligence in the domain of perceiving and understanding emotions, as well as a better ability to regulate and manage emotions compared to male respondents, while the measured scores at scale of affective attachment and self-esteem did not show statistically significant differences between gender. On further, female managers in our research see the development of rural tourism as their business opportunity.

Published: April 2021

This paper examines the earnings and cash flow persistence of selected agriculture Serbian enterprises as a measure of their earnings quality. We study the persistence of income statements and cash flow statement items of medium-sized agriculture enterprises in Serbia. Agriculture is a relevant sector for the national economy and medium-sized enterprises are the main drivers of her economic growth. We use panel regression analysis with annual data over the period from 2010 to 2018. The results of our research indicate that earnings and cash flow-based indicators have different persistence. Analysing accruals and net cash flows of operating activities as determinants of operating profit of analysed enterprises, we conclude that operating profit that represents accruals are more persistent than operating profit backed by net operating cash flows.

Despite the significant results that State Audit Institution achieved in the domain of determining regularities of doing business and truthfulness of financial reports of budget users, performance audit was given significantly less attention, which points to the necessity of developing a methodology for this discipline, as well as a technique to apply it. This contribution represents an attempt to apply a technique of finding hidden knowledge-implicit knowledge (Data mining - DM) in the process of auditing public procurement procedures and illustrating the significance of developing a technique for assessing the purposefulness of using budget assets on an example of public procurements performed in an agricultural company.
The advanced iterative learning control algorithm for rehabilitation exoskeletons
Authors: Lazarević Mihailo , Živković Nikola
Published: April 2021

In this paper an advanced iterative learning control algorithm for rehabilitation exoskeletons is proposed. A simplified biomechanical model is used as the control object to verify control algorithm feasibility. The control design is proposed as two level controller consisting of inner and outer loop. In the inner loop the feedback linearization is applied to cancel out the model nonlinearities. In the outer loop the advanced iterative learning control algorithm of sgnPDD2 type is applied as a feedforward controller and classical PD controller as a feedback controller. Uncertainties are added in order to examine the controller design robustness. Numerical simulation is carried out.
Safety in health: The evacuation of immobile persons from gerontology institution
Authors: Jevtić Radoje
Published: April 2021

Introduction/Aim: Gerontology institutions present objects with the presence of a great number of partly mobile or immobile persons. In emergency conditions, their evacuation because of noted reasons can take longer, so the aim of the research was to present several ways for the evacuation of partly mobile and immobile persons older than 70, from gerontology institutions, and to evaluate necessary evacuation time. Methods: For this research, the software Pathfinder 2020 was used for the calculation of evacuation times and predicting of potential situations during evacuation. The gerontology institution, as a used model, presents an object with a basement and four floors. All floors have 16 rooms with two patients in every room. Floors are connected with main stairs, emergency stairs and with four elevators (two cargo elevators for 12 persons per elevator, and two passenger elevators for 6 persons per elevator). The total number of medical and administrative staff is 44, and the number of users of gerontological institution services is 128. The simulation of evacuation from gerontology institution was realized for four different scenarios: The first, when all the elevators are in function and all stairs are accessible; the second, when none of the elevators works but stairs are accessible; the third, when only emergency stairs are in function; the fourth, when only main stairs are in function. Each of these four scenarios has four different situations that depend on the evaluated speed of patient`s movement. Results: The evacuation time when it is possible to use all elevators and stairs is from 895 seconds (14.9 minutes) (for the fastest movement of persons - the first situation) to 958 seconds (16 minutes) (for the slowest movement of persons - the fourth situation), for main and emergency stairs from 984 to 1111.1 seconds (16.4-18.5 minutes), only for emergency stairs from 1997.6 to 2765.3 seconds (33.3-46.1 minutes), and only for main stairs from 1365 to 2342 seconds (22.8-39.0 minutes). Conclusion: The usage of computer software Pathfinder 2020 for the simulation of evacuation presents a very important, safe and cheap way for predicting evacuation way and speed, which can contribute to the national strategy for emergency situations.

La idea es seguir aportando a la creación de una comunidad científica feminista.One of the most relevant social problems in Mexico is femicide violence. That is the reason why we need to think about solutions. This paper is based on a work in which we have carried out situated knowledges and followed some principles of the Feminist Activist Research. The work focused on collecting the experiences of relatives and activists who fight to stop femicide violence in a region of central Mexico. The article explains how research was constructed from feminist approaches and shows how to weave the collected data as a dialogue of knowledge and not a hierarchical analysis. The idea is to continue contributing to the creation of a feminist scientific community.
“Se busca”. Métodos de investigación para una aproximación feminista a mujeres detenidas por la policía
Authors: De Miguel Calvo Estibaliz
Published: April 2021

Este artículo explora cómo es posible poner en práctica métodos de investigación para analizar la experiencia de las mujeres detenidas en calabozos desde una perspectiva feminista. Presentamos el proceso metodológico desarrollado con las mujeres que pasaron por una experiencia de detención policial, prestando especial atención a las cuestiones éticas. Para ello, se realiza un análisis de la literatura sobre este objeto de investigación, se describe el contexto de la investigación, la metodología desarrollada y las decisiones tomadas sobre las técnicas de investigación más apropiadas al contexto concreto y las especificidades de las mujeres detenidas por la policía. Se ilustra la utilidad de la reunión de cierre con un doble propósito: sopesar el impacto de la investigación para las participantes y devolver los resultados. Pero el grupo de cierre posibilitó cumplir con otros objetivos no contemplados inicialmente, tales como el contraste grupal de resultados, la rendición de cuentas acerca de la marcha de la investigación y la generación de dinámicas de empatía y validación mutua En definitiva, el grupo de cierre fue mucho más allá de las expectativas iniciales, sirviendo de aprendizaje para las investigadoras acerca del enorme potencial de las técnicas grupales para el estudio de experiencias de mujeres.Más allá de lo inicialmente previsto, el grupo de cierre permitió establecer otras formas de relación con las mujeres participantes reduciendo la distancia investigadoras/participantes y facilitando formas más horizontales de generar conocimiento.This article explores how research methods can be used to analyse the experience of women in police custody from a feminist approach. Here, there are presented the methodological process developed with women who went through an experience of police detention, paying particular attention to ethical issues, through a review of the literature on this object of research, a description of the research context, the methodology developed and the decisions made about the most appropriate research techniques for the specific context and the specificities of women in police detention. The usefulness of the closing meeting is illustrated with a double purpose: to weigh the impact of the research for the participants and to return the results, But the closing group made it possible to fulfil other objectives not initially envisaged, such as group comparison of results, accountability on the progress of the research, as well as the generation of dynamics of empathy and mutual validation. In short, the closing group went far beyond the initial expectations, serving as a learning experience for the researchers about the enormous potential of group techniques for the study of women's experiences. Beyond what was initially envisaged, the focus group allowed for the establishment of other forms of relationships with the women participants, reducing the researcher/participant distance and facilitating more horizontal ways of generating knowledge.
A High Sense of Calling: Joseph Connolly, A.W. Holmes, and their Buildings for the Roman Catholic Archdiocese of Toronto, 1885-1935
Authors: Thomas Christopher A.
Published: April 2021

Pendant cinquante ans Joseph Connolly (ca. 1840-1904) et Arthur W. Holmes (1863-1944) furent les architectes attitrés des évêques de l’Église catholique de l’Ontario, en particulier de Toronto; ils ont dessiné pour eux, dans les styles traditionnels, églises, presbytères et collèges qu’exigeait l’urbanisation rapide d’une population en plein essor. Né et formé en Irlande, Connolly préféra les styles médiévaux, comme le gothique français de l’église Our Lady à Guelph (commencée en 1876) et de l’église St. Mary à Toronto (1885-1889). Il pouvait aussi cependant rendre des formes plus classiques, comme à l’église St. Paul, rue Power à Toronto (1887-1889), de style roman italien à l’extérieur, mais tout à fait classique et même académique à l’intérieur. La vogue du style classique, particulièrement du baroque, traduit en effet le conservatisme doctrinal des catholiques à cette époque et leur complète allégeance à l’égard de Rome. Arthur Holmes, architecte anglais formé par G.E. Street, puis disciple et successeur de Connolly, préféra comme ce dernier les styles médiévaux pour les églises de village et de banlieue, mais moins pour les églises urbaines; l’église St. Helen de Toronto (1908-1910) est en ce sens une exception. Après 1900, la popularité du classicisme académique et la demande pour de vastes bâtiments économiques amenèrent Holmes à dessiner plutôt ses églises urbaines à hauts murs cintrés, dans un ordre classique simple, derrière des façades baroques imposantes; les églises St. Ann et Holy Name (1914-1926), dans l’est de Toronto, en sont des exemples. Le presbytère de St. Ann, conçu en même temps que l’église, est caractéristique de la manière de Holmes pour ce type de résidence. Sa commande la plus importante pour l’archidiocèse de Toronto fut le séminaire St. Augustine à Scarborough (1910-1913), bâtiment sobre et massif à plan conventionnel, entourant une chapelle à large voûte en berceau et aux détails inspirés du baroque anglais. La préférence profonde de Holmes pour le gothique se manifestera à nouveau avec l’église Saint-François d’Assise (1914-1915), à l’extrémité ouest de Toronto, la chapelle Saint-Thomas d’Aquin de l’Université de Toronto (ca. 1927), et surtout sa charmante reproduction d’un modèle médiéval anglais pour la congrégation du Saint-Rosaire, rue St. Clair (1926-1927). Holmes termina sa carrière dans les années trente avec la collégiale gothique du St. Michael’s College à Toronto, en interprétant une fois de plus des formes traditionnelles associées à l’architecture religieuse.
‘Latens Deitas’: The Holy Sacrament Altarpiece of Dieric Bouts
Authors: Dale William S. A.
Published: April 2021

À travers les grandes lignes de composition des cinq panneaux du Retable du Saint-Sacrement de Dierck Bouts, on peut découvrir les formes cachées de lettres grecques révélant les monogrammes sacrés Alpha-Omega et Chi-Ro, et le nom médiéval contracté de Jesu. L’auteur relie le dessin de ces lettres aux alphabets fantastiques de l’époque, mais il conclut que leur emploi cryptographique est l’invention de Bouts, qui a voulu ainsi exprimer dans son retable la « présence cachée » du Christ dans le Saint-Sacrement et dans les sources de l’Ancien Testament. Le thème du retable et son illustration semblent d’autre part avoir été inspirés par les textes de la Messe et des Offices de la Fête du Saint-Sacrement de Thomas d’Aquin.
Fragmentação na unidade: uma interpretação do feminino em Natália Correia
Authors: Duarte Vânia
Published: April 2021

A obra édita e inédita de Natália Correia faz, de forma inequívoca, a apologia do feminino. Um feminino fragmentado na procura da unidade, um feminino que se define herdeiro de cosmogonias primitivas e de correntes filosófico-religiosas sincréticas que ensaiaram a redefinição de um imaginário universal masculino. Também a proposta de uma Utopia Feminina do Espírito Santo, na senda da Teoria das Três Idades de Joachim de Fiore, comprova a vontade nataliana de reorganização de uma ordem simbólica masculina, culminando na reunificação do feminino e do masculino, no que a autora designa de “Frátria”, muito na esteira do proposto por feministas como Simone de Beauvoir. Este artigo pretende, por conseguinte, apresentar as várias conceptualizações natalianas do feminino, numa perspetiva feminista.
Vestígios da trajetória de Edith Stein rumo ao Carmelo
Authors: Kirchner Renato
Published: April 2021

Edith Theresa Hedwig Stein nasceu em Breslávia, Polônia, em 1891, e morreu como mártir no Campo de Concentração de Auschwitz, em 9 de agosto de 1942. Foi canonizada como Santa Teresa Benedita da Cruz, tendo sido santa, filósofa e teóloga alemã nascida judia que se converteu à Igreja Católica. Entender a relação entre filosofia e tradição cristã em Edith Stein só é possível tento em vista sua trajetória de formação humana, cultural, cívica e religiosa de matizações diversas. Sendo assim, é possível compreender que sua trajetória espiritual está intimamente ligada às posições filosóficas e, sobretudo, a profundas experiências intelectuais e religiosas. Neste sentido, conforme enunciado no título, assumimos aqui a tarefa, na medida do possível, de encontrar e evidenciar alguns vestígios da trajetória de Edith Stein rumo ao Carmelo. Santa Teresa Benedita da Cruz foi canonizada, em 1998, por João Paulo II, que a chamou “Ilustre filha de Israel”. Em Audiência Geral de 8 de agosto de 2018, o Papa Francisco recordou a santa como “mulher de diálogo e de esperança”.
Mulher, este é o teu emblema da vergonha: Quando a mulher é objeto mas não co-sujeito da jurisdição social e religiosa
Authors: Bartolomei Teresa
Published: April 2021

Em A Letra Escarlate (1850), de Nathaniel Hawthorne, são expostas as consequências existencialmente destrutivas de uma sociedade patriarcal e de uma Igreja clerical em que a mulher é expulsa do espaço público como sujeito e destinatário normativo e acolhida nele unicamente como sujeita a (nomeadamente transgressora de) uma normatividade estabelecida exclusivamente pelo homem. Esta desigualdade não é, no entanto, prejudicial unicamente à condição social da mulher, mas também à autocompreensão geral da sociedade e dos homens em particular, ao privar a sua elaboração ética, jurídica e religiosa dos recursos hermenêuticos peculiares da experiência feminina (especialmente a da maternidade). A constelação judiciária de norma, transgressão, condenação e castigo, sobrepõe-se ideologicamente à interpretação religiosa da culpa do ponto de vista cristão, tornando incompreensível a constelação evangélica de mandamento, pecado, conversão e perdão, assim como a diferença entre castigo e expiação. Unicamente na perspetiva ‘materna’ de orientação para o futuro, gerada pelo amor e pela assunção de responsabilidade para com o humanamente ‘dado à luz’, se dá a abertura à gratuidade do amor redentivo de Deus, cuja justiça é força de salvação e não de perdição. Esta diferença de perspetiva tem consequências relevantes na moral familiar, em particular em relação aos divorciados recasados. No comportamento do padre coprotagonista do romance, de ocultamento público da própria culpa e de irresponsabilidade para com os indivíduos nela envolvidos (a antiga amante e a filha), é exposto o mecanismo patriarcal de ‘excecionalismo clerical’ ainda hoje difuso no seio da Igreja e que está na base da gestão moralmente errada e historicamente falimentar do fenómeno do abuso de menores e de pessoas vulneráveis.
Progressive Multifocal Leukoencephalopathy Risk Perception in Patients Considering Natalizumab for Multiple Sclerosis
Authors: Berkovich Regina , Eskenazi Jonathan , Yakupova Aida , Riddle Evan Lawrence
Published: April 2021

Background:

Progressive multifocal leukoencephalopathy (PML) remains a concern when considering natalizumab for multiple sclerosis (MS) treatment. Extensive research has identified factors that increase PML risk, and it is important that providers and patients accurately understand risk to make appropriate benefit-risk decisions.

Methods:

One hundred adult US patient-candidates for natalizumab therapy were questioned about their PML risk perception, the maximum PML risk they deemed acceptable, and sources of information used to understand risk. Differences in group distributions were compared.

Results:

Patients estimated their potential PML risk from 0.1% to 87% (mean, 31.5%). Maximum PML risk deemed acceptable ranged from 0.1% to 45% (mean, 14.5%). Actual risk (mean, 0.01%), based on published risk estimates, was calculated as a function of time receiving therapy, anti–John Cunningham virus antibody index, and previous use of immunosuppressants. The sexes perceived their risks similarly and had similar risk acceptance. Patient perception of PML risk increased with age, whereas willingness to accept risk remained similar among all ages. Higher levels of education correlated with more accurate risk perception and lower risk tolerance. Neither risk perception nor tolerance was correlated with disability level. Sixty-three percent of patients indicated that their primary/referring physician’s concern level regarding potential risk of PML during the benefit-risk discussion was their main source of information about risk.

Conclusions:

Patients with MS substantially overestimated their PML risk, often by three orders of magnitude. Patients with MS could benefit from accurate risk education, and providers could play an essential role in presenting PML risk information in a manner understandable to each individual patient.
Impacts of Clear Cutting on Diversity of Ground Ants (Hymenoptera: Formicidae) in Pine Plantation Forest in Sukabumi Forest Management Unit, West Java

Clear cutting is the main source of timber production of plantation forest management in Indonesia, but this activity disrupts the lives of ground ants. It is rarely known how clear cutting affects the ground ant community in the Indonesian plantation forest. The study aimed to analyze the impacts of clear cutting on the diversity of ground ants in the pine plantation forest of Sukabumi, West Java. The study compared the community structure of ground ants before clear cutting and after clear cutting. Ground ants were collected using a pitfall trap. Trapping of ground ants was carried out six days before the clear cutting and six days after the clear cutting. The ground ants were identified to the morphospecies level and classified into their functional role. The results showed that clear cutting alters the community indices of ground ants. Abundance, morphospecies composition, diversity index, richness index, and evenness index of ground ants after clear cutting was lower compared with those before clear cutting. The clear-felled area due to clear cutting provided favorable habitat for the generalist groups of ground ants, but negatively affected the predator and forager groups of ground ants. These findings can be used as an important factor in the development of environmenllyt-friendly forest harvesting systems in Indonesian plantation forests.
The Influence the Language Learning Environment on Negative Transfer and its Connection to Status and Face-Saving Refusal Strategies
Authors: Case Rod E. , Xu Wei
Published: April 2021

While there is some research into the role of the target language community in understanding negative transfer and refusals (e.g., Beebe, Takahashi, Uliss-Weltz,1990; Ikoma & Shimura, 1993; Takahashi & Beebe, 1987; Yamagashira, 2001), most research has focused on determining the extent to which L2 proficiency influences negative transfer without close attention to status of the interlocuter or face-saving strategies (e.g., Félix-Brasdefer, 2004; Chang, 2009, Jiang, 2015). In response to this gap in the research, this study reports on findings from an investigation into the negative transfer of refusals among 59 students studying in Japan and the USA. Findings demonstrated that learning environments play a role in determining the frequency of negative transfers and that negative transfer was sensitive to status. Content-related findings suggest that the production of face-saving refusals is sensitive to the learning environment as well. Implications for pragmatic research comparing L1 and L2 environments are offered.
Reconfiguring Regulation: Towards an Empathic, Person-Centred Highly Compulsory Course of Study
Authors: Mitcham Rick
Published: April 2021

This paper offers a model for a highly compulsory course designed to be empathic and person-centred within the parameters of the regulatory environment. Highly compulsory courses are those which require undergraduate students to study general subjects, in addition to subjects in their chosen academic degrees, and to satisfy the requirements within the duration of a first-degree course programme. Students who fail to comply must either remain at university until all highly compulsory courses have been successfully completed or to leave university without a degree. A relatively recent phenomenon, the highly compulsory course blueprint is being reproduced in university settings across Asia. The empathic person-centred highly compulsory course model described in the paper emerged through the interplay of three elements: an understanding of the modern regulatory environment informed by the work of philosopher-historian, Michel Foucault; an approach to writing ordinary lives extrapolated from the work of cultural historian, Catherine Hall; and real life-like scenarios based on a knowledge and understanding of the ordinary lives of students conscripted to the course that accrued in an 18-month period between 2015 and 2016. The resulting course is predicated on four principles: challenge; openness and transparency; availability; and flexibility. The first is a response to the regulatory environment’s requirement that the highly compulsory courses within its purview be meaningful from a pedagogical perspective; the other three are designed to support student-conscripts through the challenge. If neither the detail of the course nor the principles on which it is predicated convince, the three elements introduced in the first part of the paper offer a possible approach for the development of highly compulsory courses that are sensitive to, and which mitigate against conflict with, learners’ lives outside the classroom.
Contextualizing Gender’s Role in Kate Chopin’s The Awakening and Rajaa Alsanea’s Girls of Riyadh: A Comparative Historical Study
Authors: Albader Arwa Waleed
Published: April 2021

This study, through a new historicist comparative approach, strives to explore the dynamics of women in marriages and in friendships for Kate Chopin’s The Awakening and Rajaa Alsanea’s Girls of Riyadh. Although Chopin’s novel was written in 1899 and Alsanea’s in 2005, both received harsh condemnation and rejection in newspapers and book reviews when they were published, emphasizing gender`s role in both cultures. By explaining the reciprocal relationships between the texts and the newspaper reviews, and ephemera, this paper adds to scholarly understanding of how the newspapers and the critics` reflection for a certain literary text, as a human constant, can describe the gender segregation of the context`s time. Using textual analyses in the form of close readings of the female characters’ interactions with their partners and other women, and the struggle and experience of each women in both novels in terms of marriage, this paper will demonstrate links between the thoughts of critics as context and the novel as a creative historical output as both writers deftly caused great social discussions for change.

Online reviews regarding different products or services have become the main source to determine public opinions. Consequently, manufacturers and sellers are extremely concerned with customer reviews as these have a direct impact on their businesses. Unfortunately, to gain profit or fame, spam reviews are written to promote or demote targeted products or services. This practice is known as review spamming. In recent years, Spam Review Detection problem (SRD) has gained much attention from researchers, but still there is a need to identify review spammers who often work collaboratively to promote or demote targeted products. It can severely harm the review system. This work presents the Spammer Group Detection (SGD) method which identifies suspicious spammer groups based on the similarity of all reviewer’s activities considering their review time and review ratings. After removing these identified spammer groups and spam reviews, the resulting non-spam reviews are displayed using diversification technique. For the diversification, this study proposed Diversified Set of Reviews (DSR) method which selects diversified set of top-k reviews having positive, negative, and neutral reviews/feedback covering all possible product features. Experimental evaluations are conducted on Roman Urdu and English real-world review datasets. The results show that the proposed methods outperformed the existing approaches when compared in terms of accuracy.

Introduction: The automobile industry is a large and growing industry in India and this industry employs many workers as manufacturers, distributors, retailers, and automobile garage workers. Automobile garage workers suffer from many health problems among which Musculoskeletal Discomfort (MSD) is very common. Aim: To find the proportion of MSD among automobile garage workers in Chetla, Kolkata and to describe the factors associated with the musculoskeletal discomfort. Materials and Methods: The study was a work place based, observational study with cross-sectional design. The study was conducted among 101 automobile garage workers at nine automobile garages of Chetla, Kolkata. A pre-designed, pre-tested structured schedule was used to collect data. The outcome variable was MSD and it was assessed using Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). MSD score was categorised into mild, moderate and severe discomfort. Data was analysed using IBM SPSS Software version 16. Results: Around one-third (30.7%) study participants belonged to the age group 41-50 years with mean (SD) age 43.35 (13.46) years. Knee discomfort was present among 42% study participants while 21% had low back pain according to CMDQ tool. Around three fourth (73.3%) study participants had at least one kind of MSD and around 46.6% had moderate to severe musculoskeletal discomfort. MSD was significantly associated with increasing age and increasing duration of working hours per week in univariate and multivariable logistic regression. Conclusion: The proportion of musculoskeletal discomfort among automobile workers was quite high. Early diagnosis and regular screening of MSD is very much needed to introduce appropriate preventive and treatment measures at appropriate time.

Introduction: Decision-making process of healthcare professionals in an acute care setting is inevitable that necessitates a balancing paradigm of clinical knowledge with the practices of evidence-based implementation. Nurses face contextual challenges in managing the issues of decision-making intervening domains of cognition, skills, and values. Aim: This study was implemented to determine the decision-making processes used by registered nurses in wound care management in acute care settings. Materials and Methods: A qualitative method was adopted using a thematic analysis approach. Fifteen nurses involved in the management of wound care unit were purposefully included in the interview from 23rd May to 15th July 2020. The semi-structured face-to-face interview was conducted, and the collected data was analysed through inductive thematic analysis. Results: Fifteen nurses working at a tertiary hospital with a mean age of 34.26±3.31 years experience ranging from 3 to 15 years were included in this study. The transcribed interviews were categorised under five themes: Foundation Knowledge and Education; Randomness in seeking practice education; Expert opinion and Evidence-based practice; Multidisciplinary Coordination and Streamlining; and Patient engagement in care. Conclusion: Nurses demonstrated that wound care management requires the practice of decision-making that requires multidisciplinary and holistic approaches tempered with knowledge about the patient and the expertise of others.

Generally, dental tooth fixtures are made of conventional metals like titanium, gold, silver etc and also some other materials like Acrylic and porcelain. These fixtures are either too expensive to make or are delicate and would deteriorate after a certain number of cycles. Therefore, a possibility of using composite materials was looked at owing to its high strength to weight ratio under compressive conditions, durability and cost. On conducting research on various materials available, Hydroxyapatite in combination with Zirconia was chosen to be the ideal material. This pair was tested for the weaker one among them and the results are established conclusively which confirmed that it is indeed a viable option to go for.
Bending and low‐frequency vortex shedding of flexible cylinders in laminar shear flow
Authors: Derksen Jos J.
Published: April 2021

Simulations of the interaction between flexible cylinders attached to a solid surface and a laminar shear flow have been performed. The flow simulations fully resolve the geometrical details and are based on the lattice‐Boltzmann method. An immersed boundary method is used to impose the no‐slip conditions at the cylinder surfaces and to determine the distribution of hydrodynamic forces over the cylinder. The latter are responsible for the bending deformation of the cylinders. We first study simple shear systems under steady conditions for which experimental data are available that we use for validation. We then study flexible cylinders in Poiseuille flow that exhibit vortex shedding and demonstrate that the flexibility of the cylinders has a pronounced effect on the temporal behavior of the flow system.
