Authors: Wei Zhenyu , Huang Jianqiu , Chen Wenhao , Huang Qingan
Published: July 2021

Porous polytetrafluoroethylene (PTFE) is physically flexible, thermally and chemically stable, relatively inexpensive, and commercially available. It is attractive for various flexible sensors. This paper has studied flexible capacitive humidity sensors fabricated on porous PTFE substrates. Graphene oxide (GO) was used as a sensing material, both hydrophobic and hydrophilic porous PTFE as the substrates, and interdigitated electrodes on the PTFE substrates were screen-printed. SEM and Raman spectrum were utilized to characterize GO and PTFE. An ethanol soak process is developed to increase the yield of the humidity sensors based on hydrophobic porous PTFE substrates. Static and dynamic properties of these sensors are tested and analyzed. It demonstrates that the flexible capacitive humidity sensors fabricated on the ethanol-treated hydrophobic PTFE exhibit high sensitivity, small hysteresis, and fast response/recovery time.

Published: July 2021

With the ongoing efforts for widespread Internet of Things (IoT) adoption, one of the key factors hindering the wide acceptance of IoT is security. Securing IoT networks such as the electric power grid or water supply systems has emerged as a major national and global priority. To address the security issue of IoT, several studies are being carried out that involve the use of, but are not limited to, blockchain, artificial intelligence, and edge/fog computing. Authentication and authorization are crucial aspects of the CIA triad to protect the network from malicious parties. However, existing authorization and authentication schemes are not sufficient for handling security, due to the scale of the IoT networks and the resource-constrained nature of devices. In order to overcome challenges due to various constraints of IoT networks, there is a significant interest in using machine learning techniques to assist in the authentication and authorization process for IoT. In this paper, recent advances in authentication and authorization techniques for IoT networks are reviewed. Based on the review, we present a taxonomy of authentication and authorization schemes in IoT focusing on machine learning-based schemes. Using the presented taxonomy, a thorough analysis is provided of the authentication and authorization (AA) security threats and challenges for IoT. Furthermore, various criteria to achieve a high degree of AA resiliency in IoT implementations to enhance IoT security are evaluated. Lastly, a detailed discussion on open issues, challenges, and future research directions is presented for enabling secure communication among IoT nodes.
MSF-Net: Multi-Scale Feature Learning Network for Classification of Surface Defects of Multifarious Sizes
Authors: Xu Pengcheng , Guo Zhongyuan , Liang Lei , Xu Xiaohang
Published: July 2021

In the field of surface defect detection, the scale difference of product surface defects is often huge. The existing defect detection methods based on Convolutional Neural Networks (CNNs) are more inclined to express macro and abstract features, and the ability to express local and small defects is insufficient, resulting in an imbalance of feature expression capabilities. In this paper, a Multi-Scale Feature Learning Network (MSF-Net) based on Dual Module Feature (DMF) extractor is proposed. DMF extractor is mainly composed of optimized Concatenated Rectified Linear Units (CReLUs) and optimized Inception feature extraction modules, which increases the diversity of feature receptive fields while reducing the amount of calculation; the feature maps of the middle layer with different sizes of receptive fields are merged to increase the richness of the receptive fields of the last layer of feature maps; the residual shortcut connections, batch normalization layer and average pooling layer are used to replace the fully connected layer to improve training efficiency, and make the multi-scale feature learning ability more balanced at the same time. Two representative multi-scale defect data sets are used for experiments, and the experimental results verify the advancement and effectiveness of the proposed MSF-Net in the detection of surface defects with multi-scale features.
Racial Disparities in Police Crime Victimization
Authors: Stinson Philip Matthew , Wentzlof Chloe Ann , Liederbach John , Brewer Steven L.
Published: July 2021

Policing has become a topic of intense public scrutiny and protest in the aftermath of several recent highly questionable and violent police–citizen encounters including the acts of police violence against George Floyd in Minneapolis (MN), Breonna Taylor in Louisville (KY), and Jacob Blake in Kenosha (WI). These encounters have led to large-scale street protests, the legitimization of the Black Lives Matter movement, and what many commentators perceive as a “national reckoning” on the issue of racial justice. The focus of our research is on police crime—a particular form of police misconduct that involves the criminal arrest of police officers. Our work is designed to identify cases in which law enforcement officers have been arrested for any type of criminal offense(s). One area of police scholarship that has thus far been neglected is the relationship between citizen race and the perpetration of police crime. We are aware of no existing empirical studies on whether, and if so, to what degree, citizen race is associated with crimes committed by police officers. The public has been forced to re-examine and question the role and legitimacy of police against the backdrop of protests and concerns about how police may contribute to racial injustice and discrimination. The broadest research issue involved an examination of the association between police crime and the race of the victim. Our goal was to identify and examine any racial disparities of police crime overall and within specific types of police crime. The analyses compared police crimes committed against Black victims to all other police crimes identified within the dataset. More specifically, we examined the degree to which police crimes perpetrated against Black victims tend to be more violent than those perpetrated against non-Black victims. CHAID regression models were utilized to explore any multivariate relationships between race and police crime. Data were derived from published news articles using the Google News search engine and its Google Alerts email update service. Our database currently includes information on more than 18,700 cases of police crime from years 2005–2021. The study utilized data derived from this larger project. The study examined those cases of police crime in which we have identified a victim and recorded information on the race of the victim. The dataset for this study includes information on 865 criminal arrest cases of sworn nonfederal law enforcement officers within the United States from 2005 through 2014.
Financial Additionality of Multilateral Development Banks in Private Participation in Infrastructure Projects
Authors: Taguchi Hiroyuki , Yasumura Kota
Published: July 2021

This paper aims to provide empirical evidence for demonstrating financial additionality of multilateral development banks (MDBs) in private participation in infrastructure (PPI) projects in terms of financing beyond what is available in the markets. To verify MDB financial additionality, this study examines whether the PPI projects with multilateral support have significantly larger investment commitments than the total average projects by using the PPI database of the World Bank for 1996–2020. The empirical analysis identifies MDB financial additionality, in that the larger investment commitments of multilateral-supported projects beyond the average are confirmed in any income levels and regions in host countries and any sectors and types in the projects. In particular, MDB financial additionality is valid even in low-income countries where private finance is still too premature to be available. In the host countries where their government effectiveness is in the poorest edge, however, MDB financial additionality loses its significance, thereby requiring the governance enhancement and capacity building in the host countries and innovative blended finance instruments for its additionality to work.
Chemical Modification of Combusted Coal Gangue for U(VI) Adsorption: Towards a Waste Control by Waste Strategy
Authors: Gao Yuan , Huang Jiandong , Li Meng , Dai Zhongran , Jiang Rongli , Zhang Jixiong
Published: July 2021

Uranium mining waste causes serious radiation-related health and environmental problems. This has encouraged efforts toward U(VI) removal with low cost and high efficiency. Typical uranium adsorbents, such as polymers, geopolymers, zeolites, and MOFs, and their associated high costs limit their practical applications. In this regard, this work found that the natural combusted coal gangue (CCG) could be a potential precursor of cheap sorbents to eliminate U(VI). The removal efficiency was modulated by chemical activation under acid and alkaline conditions, obtaining HCG (CCG activated with HCl) and KCG (CCG activated with KOH), respectively. The detailed structural analysis uncovered that those natural mineral substances, including quartz and kaolinite, were the main components in CCG and HCG. One of the key findings was that kalsilite formed in KCG under a mild synthetic condition can conspicuous enhance the affinity towards U(VI). The best equilibrium adsorption capacity with KCG was observed to be 140 mg/g under pH 6 within 120 min, following a pseudo-second-order kinetic model. To understand the improved adsorption performance, an adsorption mechanism was proposed by evaluating the pH of uranyl solutions, adsorbent dosage, as well as contact time. Combining with the structural analysis, this revealed that the uranyl adsorption process was mainly governed by chemisorption. This study gave rise to a utilization approach for CCG to obtain cost-effective adsorbents and paved a novel way towards eliminating uranium by a waste control by waste strategy.
Structural Equation Approach to Analyze Cyclists Risk Perception and Their Behavior Riding on Two-Lane Rural Roads in Spain
Authors: López Griselda , Arroyo Rosa , García Alfredo
Published: July 2021

The use of bicycles on two-lane rural roads in Spain has been increasing in recent years. However, these roads have no bicycle infrastructure, being cyclists forced to share the road and interact with motorized vehicles. In rural environments, the interaction between road users from the cyclist’s point of view is still not well understood. To analyze it, the relationships between risk perceptions and behavioral factors of rural cyclists according to their demographic characteristics, profile, and self-reported knowledge on traffic rules were obtained. An online survey was used, which collected the opinion of 523 cyclists. Data were analyzed by using structural equation models. The Thurstonian Item Response Theory approach was adopted to include raking responses. Different perceptions among demographic groups were found. Younger cyclists present the lowest risk perception while having a higher risk behavior. The knowledge about traffic rules was correlated with safety behavior, showing the importance of this factor. These results are in line with urban cycling. However important differences under risk elements for rural cyclists, mainly associated with potential hazards on the shoulder, have been drawn. These findings may help policy makers to integrate cycling with vehicular traffic on two-lane rural roads in a safe way.
Sustainable Development Goals in Early COVID-19 Prevention and Control
Authors: Kim Taejong , Kim Hyosun
Published: July 2021

Recent failures in COVID-19 prevention and control in some of the richest countries raise questions about the relevance of Sustainable Development Goals (SDGs) in the fight against pandemics. To examine this issue, we adopted the measure of countries’ progress for the SDGs in the SDG Index Scores (SDGS) and employed two analytical devices. The first was regression-aided adjustment of the number of deaths and confirmed cases. The second was the use of robust regressions to control the undue influence of outliers. The results are mixed. Between the SDGS and the adjusted infection rates, we found no significant correlation; however, between the SDGS and the adjusted death rates, the correlation was negative and statistically significant. These results provide a nuanced contrast to the hasty conclusions some of us might be tempted to draw from apparent positive correlations between SDGS and the cases and the deaths. The SDGs represent the fruit of painstaking global efforts to encourage and coordinate international action to enhance sustainability. We find the results reassuring, in that they suggest that the countries with higher SDGS have been able to control the devastation of deaths from COVID-19 more effectively, despite being unable to control the propagation of infections.

The COVID-19 pandemic has exposed new aspects of sustainable entrepreneurship and the resilience of SMEs in the conditions of individual countries. This empirical study contributes to entrepreneurship sustainability literature and business resilience literature by estimating the impact of various utilized internal crisis management tools and state compensation measures on retaining the pre-crisis levels of employment after two waves of the pandemic on the conditions of a V4 country. The study adopts an econometric approach towards assessing the influence of key factors of mitigating the problems caused by the pandemic, and the results suggest a crucial role of digitalization, internal policies optimizing variable costs, and utilization of direct governmental supportive measures to compensate for restrictions in force for employment retention in knowledge-intensive SMEs. According to the results, knowledge-intensive SMEs appears to have increased resilience towards economic shocks due to the capability to swiftly change the management of ventures to adapt to a crisis.
Societal Changes Due to “COVID-19”. An Analysis of the Tourism Sector of Galicia, Spain
Authors: Araújo-Vila Noelia , Fraiz-Brea Jose A. , Pereira Alexandra Matos
Published: July 2021

With the outbreak of the COVID-19 pandemic, an unprecedented global health and economic crisis started. This situation has had a devastating effect on all economic and social sectors, provoking either a decrease or cessation of business or profound changes in life habits. One of the most affected industries has been tourism, due to the resulting travel restrictions and a sharp drop in demand among travellers as well as temporary hotel and restaurant closures. Thus, the primary purpose of this study is to analyse the changes during the pandemic in individual consumers’ behaviour patterns in the tourism sector. Predictive market research techniques through quantitative analysis were carried out via surveys (n = 712). One of the more significant findings to emerge from this study is that recollection of these times will be in people’s minds for a long time after the pandemic. Notably, tourists will reward safety over leisure and will continue to undertake independent tours with their own vehicles. Findings also proved—and for the tourism sector this is good news—that travellers’ trust will be rebuilt, and tourists will be travelling again.
Sustainable Development Goals Localisation in the Hospitality Sector in Botswana and Zimbabwe
Authors: Dube Kaitano
Published: July 2021

Many countries have fronted tourism as a tool for achieving Sustainable Development Goals (SDGs) in their voluntary national reviews. Nevertheless, very few studies have examined how the tourism industry has been localising SDGs. Therefore, this study is borne out of that knowledge gap. A qualitative approach comprising the use of primary and secondary data from integrated annual reports was adopted. The study found some progress made by hotel companies in localising SDGs. It emerged that Cresta Hotels and the African Sun group of hotels are only at the inception stage of SDG localisation, focusing on several SDGs that respond to the socio-economic and environmental demands of the environments they work in. Given that most of the work under the SDGs only began inception between 2018 and 2019, there is still a long way to go before meaningful progress can be reported regarding SDG localization, with preliminary evidence showing that the hotel industry is likely to have made significant inroads when the SDGs lapse in 2030 if their efforts are not disturbed by the COVID-19 pandemic. The study recommends continuous monitoring and support for the sector as the SDG framework offers a better and more focused sector to achieve sustainable and responsible tourism in Zimbabwe and Botswana.

Published: July 2021

Pearl millet (Pennisetum glaucum) is a staple food crop in Burkina Faso that is widely grown in the Sahelian and Sudano-Sahelian zones, characterised by poor soil conditions and erratic rainfall, and high temperatures. The objective of this study was to document farmers’ perceptions of the prevailing constraints affecting pearl millet production and related approaches to manage the parasitic weeds S. hermonthica. The study was conducted in the Sahel, Sudano-Sahelian zones in the North, North Central, West Central, Central Plateau, and South Central of Burkina Faso. Data were collected through a structured questionnaire and focus group discussions involving 492 participant farmers. Recurrent drought, S. hermonthica infestation, shortage of labour, lack of fertilisers, lack of cash, and the use of low-yielding varieties were the main challenges hindering pearl millet production in the study areas. The majority of the respondents (40%) ranked S. hermonthica infestation as the primary constraint affecting pearl millet production. Respondent farmers reported yield losses of up to 80% due to S. hermonthica infestation. 61.4% of the respondents in the study areas had achieved a mean pearl millet yields of <1 t/ha. Poor access and the high cost of introduced seed, and a lack of farmers preferred traits in the existing introduced pearl millet varieties were the main reasons for their low adoption, as reported by 32% of respondents. S. hermonthica management options in pearl millet production fields included moisture conservation using terraces, manual hoeing, hand weeding, use of microplots locally referred to as ‘zaï’, crop rotation and mulching. These management techniques were ineffective because they do not suppress the below ground S. hermonthica seed, and they are difficult to implement. Integrated management practices employing breeding for S. hermonthica resistant varieties with the aforementioned control measures could offer a sustainable solution for S. hermonthica management and improved pearl millet productivity in Burkina Faso.
Kernel-Free Quadratic Surface Minimax Probability Machine for a Binary Classification Problem
Authors: Wang Yulan , Yang Zhixia , Yang Xiaomei
Published: July 2021

In this paper, we propose a novel binary classification method called the kernel-free quadratic surface minimax probability machine (QSMPM), that makes use of the kernel-free techniques of the quadratic surface support vector machine (QSSVM) and inherits the advantage of the minimax probability machine (MPM) without any parameters. Specifically, it attempts to find a quadratic hypersurface that separates two classes of samples with maximum probability. However, the optimization problem derived directly was too difficult to solve. Therefore, a nonlinear transformation was introduced to change the quadratic function involved into a linear function. Through such processing, our optimization problem finally became a second-order cone programming problem, which was solved efficiently by an alternate iteration method. It should be pointed out that our method is both kernel-free and parameter-free, making it easy to use. In addition, the quadratic hypersurface obtained by our method was allowed to be any general form of quadratic hypersurface. It has better interpretability than the methods with the kernel function. Finally, in order to demonstrate the geometric interpretation of our QSMPM, five artificial datasets were implemented, including showing the ability to obtain a linear separating hyperplane. Furthermore, numerical experiments on benchmark datasets confirmed that the proposed method had better accuracy and less CPU time than corresponding methods.

Published: July 2021

Tubular epithelial cells of the human kidney are considered as targets of Shiga toxins (Stxs) in the Stx-mediated pathogenesis of hemolytic–uremic syndrome (HUS) caused by Stx-releasing enterohemorrhagic Escherichia coli (EHEC). Analysis of Stx-binding glycosphingolipids (GSLs) of primary human renal proximal tubular epithelial cells (pHRPTEpiCs) yielded globotriaosylceramide (Gb3Cer) and globotetraosylceramide (Gb4Cer) with Cer (d18:1, C16:0), Cer (d18:1, C22:0), and Cer (d18:1, C24:1/C24:0) as the dominant lipoforms. Investigation of detergent-resistant membranes (DRMs) and nonDRMs, serving as equivalents for the liquid-ordered and liquid-disordered membrane phase, respectively, revealed the prevalence of Gb3Cer and Gb4Cer together with cholesterol and sphingomyelin in DRMs, suggesting lipid raft association. Stx1a and Stx2a exerted strong cellular damage with half-maximal cytotoxic doses (CD50) of 1.31 × 102 pg/mL and 1.66 × 103 pg/mL, respectively, indicating one order of magnitude higher cellular cytotoxicity of Stx1a. Surface acoustic wave (SAW) real-time interaction analysis using biosensor surfaces coated with DRM or nonDRM fractions gave stronger binding capability of Stx1a versus Stx2a that correlated with the lower cytotoxicity of Stx2a. Our study underlines the substantial role of proximal tubular epithelial cells of the human kidney being associated with the development of Stx-mediated HUS at least for Stx1a, while the impact of Stx2a remains somewhat ambiguous.

Yellow fever virus remains a major threat in low resource countries in South America and Africa despite the existence of an effective vaccine. In Senegal and particularly in the eastern part of the country, periodic sylvatic circulation has been demonstrated with varying degrees of impact on populations in perpetual renewal. We report an outbreak that occurred from October 2020 to February 2021 in eastern Senegal, notified and managed through the synergistic effort yellow fever national surveillance implemented by the Senegalese Ministry of Health in collaboration with the World Health Organization, the countrywide 4S network set up by the Ministry of Health, the Institut Pasteur de Dakar, and the surveillance of arboviruses and hemorrhagic fever viruses in human and vector populations implemented since mid 2020 in eastern Senegal. Virological analyses highlighted the implication of sylvatic mosquito species in virus transmission. Genomic analysis showed a close relationship between the circulating strain in eastern Senegal, 2020, and another one from the West African lineage previously detected and sequenced two years ago from an unvaccinated Dutch traveler who visited the Gambia and Senegal before developing signs after returning to Europe. Moreover, genome analysis identified a 6-nucleotide deletion in the variable domain of the 3′UTR with potential impact on the biology of the viral strain that merits further investigations. Integrated surveillance of yellow fever virus but also of other arboviruses of public health interest is crucial in an ecosystem such as eastern Senegal.
How Epstein–Barr Virus and Kaposi’s Sarcoma-Associated Herpesvirus Are Maintained Together to Transform the Same B-Cell
Authors: Sugden Arthur U. , Hayes Mitch , Sugden Bill
Published: July 2021

Epstein–Barr virus (EBV) and Kaposi’s sarcoma-associated herpesvirus (KSHV) independently cause human cancers, and both are maintained as plasmids in tumor cells. They differ, however, in their mechanisms of segregation; EBV partitions its genomes quasi-faithfully, while KSHV often clusters its genomes and partitions them randomly. Both viruses can infect the same B-cell to transform it in vitro and to cause primary effusion lymphomas (PELs) in vivo. We have developed simulations based on our measurements of these replicons in B-cells transformed in vitro to elucidate the synthesis and partitioning of these two viral genomes when in the same cell. These simulations successfully capture the biology of EBV and KSHV in PELs. They have revealed that EBV and KSHV replicate and partition independently, that they both contribute selective advantages to their host cell, and that KSHV pays a penalty to cluster its genomes.

Single Incision Laparoscopic Surgery (SILS) in Small Animals: A Systematic Review and Meta-Analysis of Current Veterinary Literature
Authors: Lacitignola Luca , Guadalupi Marta , Massari Federico
Published: July 2021

In veterinary surgery, single incision laparoscopic surgery (SILS) techniques have been described since 2009, and, in recent decades, many authors have reported the application of SILS in small animals, thus, promoting the wide dissemination of this novel approach among veterinary laparoscopists. The aim of this literature review is to provide a critical evaluation of the scientific reports on SILS in the field of small animal laparoscopic surgery. A comprehensive literature review was performed including from 1 January 2009 to 1 July 2020. The following data were recorded from each study: the design, year of publication, surgical procedure, species, number of animals included, and surgical time. The type of SILS technique and type of control group technique were evaluated. In total, 90 articles were identified through database searches and manual searches. The qualitative analysis showed that most of the articles were retrospective studies, without a control group or case series. A meta-analysis was performed on the eight controlled studies, showing that SILS ovariectomy and gastrointestinal procedures had a comparable surgical time to multiport techniques. The study of the articles available in the veterinary literature did not allow for an adequate meta-analysis of the published results, especially regarding post-operative pain, evaluations of surgical times, and post-operative complications in comparison to multiport techniques. Therefore, veterinary surgeons who want to employ these techniques must consider the real advantages of SILS techniques.

Dentre as pessoas que realizaram, a maior parte informou utilizar medicação prescrita (7,2%), pilates (5,6%) e automedicação (4,8%). A intensidade da dor foi semelhante à de outros estudos (média de 6,05±2,77). A maioria informou não ter impedimentos para realizar atividades (76%) e a incapacidade causada pela dor caracterizou-se como moderada (média de 29,46±18,87). A média de estresse percebido condiz com resultados de estudos nacionais (19,06±4,73). Conclusão: O conhecimento dessa realidade pode subsidiar o planejamento de políticas e implementação de estratégias que contribuam com a promoção da saúde dos trabalhadores e qualidade de vida no trabalho.
Dimensão fractal e lacunaridade como parâmetros de avaliação da qualidade óssea na mandíbula de indivíduos saudáveis: análise por meio da tomografia computadorizada de feixe cônico
Authors: Cambraia Faria Gabrielle , Ramos de Faria Fernanda , De Sá Werneck Carolina , Davi Rabelo Gustavo , José da Silva Campos Marcio
Published: July 2021

Introdução: A qualidade óssea pode ser avaliada pela análise de textura nos exames de imagem, por meio da mensuração da dimensão fractal (DF) e lacunaridade (Lac). A DF está relacionada com a complexidade da organização estrutural óssea e a Lac representa a distribuição e o tamanho dos espaços vazios. Objetivo: Avaliar a qualidade óssea trabecular em região posterior da mandíbula por meio da DF e Lac e analisar o volume ósseo no exame de tomografia computadorizada de feixe cônico (TCFC), em indivíduos saudáveis, e, ainda, comparando homens e mulheres. Material e Métodos: 21 exames de TCFC foram utilizados. Utilizou-se o software ImageJ com dez cortes axiais sequenciais de cada paciente, delimitando a região de interesse (ROI) entre canino e primeiro molar inferiores, de ambos os lados. Foram avaliados os parâmetros: a) Bone Volume (BV), Tissue Volume (TV) e BV/TV, pelo processo de binarização; b) DF e Lac pelo método de Box-couting, em escala de cinza, sem binarização. Resultados: Na comparação entre os lados, BV e TV apresentaram diferença significativa (p=0,02 e 0,01, respectivamente), com maiores valores para o lado direito. Na comparação entre os sexos não houve diferença significativa. Os valores de DF apresentaram média de 0,87 para mulheres e 0,86 para homens. Valores de Lac foram em média 0,17 para mulheres e 0,15 para homens. A idade apresentou correlação negativa significativa com o volume ósseo. Conclusão: DF e Lac são parâmetros viáveis para serem analisados quando se trata de acessar a qualidade óssea trabecular em mandíbula. Foram encontrados valores menores que 1 para DF, e abaixo de 0,17 para Lac, em indivíduos saudáveis. Tanto DF quanto Lac não mostraram diferenças entre homens e mulheres. O osso trabecular na região posterior da mandíbula apresentou maior volume no lado direito em comparação ao esquerdo, e não houve diferença entre os sexos.

Published: July 2021

Introdução: A atuação dos profissionais de saúde da atenção primária à saúde demonstra qualificação insuficiente para assegurar a redução da carga da hanseníase. Há uma demanda crescente de educação permanente para esses profissionais com o intuito de ressignificar seu compromisso na implementação e fortalecimento das ações de prevenção e controle da doença. Objetivo: Relatar a experiência no desenvolvimento de capacitações em ações de controle de hanseníase para profissionais da atenção primária à saúde. Relato de Experiência: Nos meses de outubro e novembro de 2019, foram realizadas capacitações dirigidas a enfermeiros e médicos inseridos em 43 unidades de saúde de Divinópolis, Minas Gerais. O treinamento teve carga horária total de 12 horas, sendo oito horas teóricas e quatro horas de prática. Os conteúdos teóricos foram organizados em cinco unidades temáticas: epidemiologia da hanseníase; diagnóstico e tratamento; avaliação e monitoramento da função neural; prevenção de incapacidades; vigilância epidemiológica e organização do serviço. O total de três enfermeiras com expertise na temática foram responsáveis pela sua condução. O total de 90 profissionais, sendo 35 médicos e 45 enfermeiros foram capacitados. Findada a capacitação, dois novos casos foram diagnosticados pelos profissionais no ano de 2019 e oito casos em 2020. Conclusão: As capacitações foram capazes de mobilizar e preparar os profissionais de saúde para a realização das ações de controle da hanseníase.

Published: July 2021

The liberalization of the operation of European airports is concerned with the influence of these factors on the development of air transport in Europe. The basic theoretical background is elaborated in the article. Air transport has had to make significant technological developments to come to the state as we know it today. At the same time, a new regulation and measures must be adopted, which were then not previously necessary given the nature of the air transport in the past. The measures that have shaped the current state of air transport in Europe, also known as liberalization measures, have fundamentally affected the development of air transport in Europe, which has also affected other areas of the industry.

Un siniestro humanitarismo como pathos contemporáneo en Os Anões de Veronica Stigger
Authors: Kelly Carolina
Published: July 2021

A partir de una serie de lecturas críticas que postulan una contemporánea sintomatología de la modernidad literaria como desilusión, desengaño y desconfianza de toda utopía (Garramuño 2009), este trabajo intenta pensar de qué manera el libro Os anões (2010) de Verônica Stigger es ejemplar, como respuesta artística a este panorama de problemas críticos, culturales y epistemológicos, para reflexionar sobre los alcances, los sentidos y las tensiones que emergen de este viejo-nuevo debate. En última instancia, desde la experiencia de lectura de un objeto contemporáneo, este trabajo buscar dar cuenta de lo siniestro de un “humanitarismo ilustrado” que nos interpela como pathéticos protagonistas de la serie discontinua de espectáculos enanos, pobres y éxtimos que se escenifican.

Drácula y la teología
Authors: Ventura Virginia
Published: July 2021

Existe un mito moderno, el del vampiro. Los románticos habían pensado en la necesidad de crear nuevos mitos, y la literatura tenía que ser la encargada de eso. Bram Stoker fue el encargado de configurar al vampiro más icónico y mítico que daría la literatura. A pesar de que su historia tiene un origen de mito moderno nacido en Rumania, y que Polidori, Le Fanu y muchos otros escribieron sobre este mito, este símbolo de lo erótico y lo tanático alcanza su forma final con Drácula. En la novela, el autor hace que este ser horroroso se convierta en un aristócrata y su simbología crezca. En esa simbología, se manifiesta el problema de la fe moderna, la angustia de la existencia que padece el hombre moderno.
Las categorías tipos de discurso y secuencias textuales en el género de texto debate: desarrollo de un razonamiento lógico-argumentativo en un diálogo monologal artificial
Authors: Navarro Paula
Published: July 2021

El objetivo de este artículo es caracterizar la composición discursiva del género de texto debate a partir de relevar la distribución de los tipos de discursos y de las secuencias textuales en un corpus de debates auténticos conformado por las intervenciones de los participantes del programa televisivo “El Debate en la Televisión Pública” y por las textualizaciones orales de estudiantes de tercer año de la escuela secundaria “Superior de Comercio Libertador General San Martín” de Rosario. Nuestro análisis demostró que la infraestructura general de este género oral institucionalizado combina los tipos de discursos del orden del exponer (teórico, interactivo y mixto) con las secuencias textuales dialogal y argumentativa según las restricciones que detentan los roles sociales y finalidades de los participantes que co-gestionan la producción del debate (moderador y argumentadores). Específicamente, los participantes que argumentan despliegan un razonamien-to lógico-argumentativo, en combina-ción con uno interactivo-dialogal, en el marco de una configuración artificial de interacción dialógica o diálogo monologal que es regulado por un moderador.
