Nuevas rutas en el desarrollo de la teoría de las representaciones sociales
Authors:   Universidad Nacional Autónoma de México, González Pérez Marco Antonio
Published: June 2021

El propósito de este artículo es presentar algunas rutas que transitan, actualmente, los estudios de representaciones sociales, en América Latina, con base en una revisión documental del estado del arte sobre el tema. Se observan nociones tradicionales que permanecen, otras que se han transformado y conceptualizaciones novedosas. Se aprecia un auge de estos estudios debido a los procesos de cambio social que reclaman una comprensión psicosocial con orientación histórica-cultural. La lucha contra el neoliberalismo ha impuesto un modelo de hacer ciencia social positivista, individualista, sin relevancia social, que genera la búsqueda de interpretaciones críticas de los fenómenos representacionales. Se observan interesantes intentos de vinculación teórica y aplicaciones relevantes en campos del conocimiento diferentes, como la comunicación, la educación y la ciencia política. Se presentan las formas de análisis de las representaciones sociales desde las perspectivas procesual y de producto. Finalmente, se discute el devenir de la teoría iniciada por Moscovici.

Resumo

Ao longo dos anos, a Geografia demonstra grande preocupação com a relação inerente entre o homem e a natureza. Não é possível deixar de notar a associação existente entre a degradação ambiental, a desigualdade social e as práticas capitalistas de exploração e esgotamento dos recursos naturais. Tal ligação evoca o conceito de justiça social e seus aspectos, discutidos neste ensaio, o qual considera as relações sociais, de poder, e o meio ambiente, observa a possibilidade de equidade na distribuição de recursos, e compreende a perspectiva que conecta a desigualdade ambiental à desigualdade social.

Palavras-chave: Ecologia política. Meio ambiente. Justiça ambiental.

Abstract 

Over the years, Geography has shown great concern upon the inherent relationship between man and nature. One cannot fail to notice the relationship between environmental degradation, social inequality, and capitalist practices of exploitation and depletion of natural resources. Such association evokes the social justice concept and its aspects, discussed in this essay, which considers social and power relations and the environment, observes equity possibility in resources distribution, and understands the perspective that connects environmental inequality to social inequality.

Keywords: Political Ecology. Environment. Environmental Justice.

AUDIÊNCIA DE CUSTÓDIA: EFETIVAÇÃO DO DIREITO FUNDAMENTAL AO CONTRADITÓRIO COMO LEGITIMAÇÃO DA DECISÃO JUDICIAL
CUSTODY HEARING: FUNDAMENTAL RIGHT TO CONTRADICTORY AS LEGITIMACY TO THE COURT DECISION

Published: June 2021

Trata-se de artigo que busca definir uma base sólida para a construção de um processo penal constitucional e democrático. O processo penal precisa abandonar funções que em nada contribuem para a solidificação do Estado de Direito. O trabalho tem por foco a análise da reforma das medidas cautelares implementadas pela Lei n. 12.403/2011 que, apesar de representar grandes avanços, ficou aquém da expectativa quanto à efetivação do princípio do contraditório. A participação do acusado na construção de um provimento jurisdicional o coloca de vez como um dos atores no processo penal e não mais como mero expectador ou objeto. A audiência de custódia atende aos preceitos fundamentais previstos no Pacto de São José da Costa Rica, do qual o Brasil é signatário. Nesse diapasão, imprescindível alinhar a legislação interna aos direitos e garantias fundamentais, por meio da aprovação do Projeto de Lei n. 554 de 2011, que trata da apresentação imediata do flagranteado perante o juiz. A introdução da audiência de custódia em nosso ordenamento jurídico coloca o Brasil no mesmo nível de avanço processual penal de países que já prevêem esse importante instituto.
DA LÓGICA CLÁSSICA À LÓGICA DEÔNTICA: COMO O DISCURSO PRÁTICO RACIONAL GERAL DE ALEXY LIDA COM AS INCERTEZAS INERENTES AO DISCURSO JURÍDICO NA BUSCA DA PRETENSÃO DE CORREÇÃO?
FROM CLASSICAL LOGIC TO DEONTIC LOGIC: HOW DOES ALEXY'S GENERAL PRACTICAL RATIONAL DISCOURSE DEAL WITH UNCERTAINTIES INHERENT TO THE LEGAL DISCOURSE IN ORDER TO SEEK A CLAIM TO CORRECTNESS?

Published: June 2021

O discurso jurídico, por ser baseado na comunicação, está também marcado pelas incertezas e ambiguidades inerentes da linguagem natural. Para tentar lidar com essas incertezas no ato comunicativo e nas contradições tipicamente presentes no comportamento humano, o discurso prático racional geral de Alexy busca uma pretensão de correção com base em uma fundamentação racional das proposições normativas valendo-se não só da lógica deôntica, mas, principalmente, do aspecto comportamental humano presente em um discurso que mais se aproxima do conceito de racionalidade. Cabe este artigo demonstrar como essas idéias lidam com as incertezas inerentes ao discurso jurídico e como a metodologia procedimental presente no discurso prático racional geral, na busca da pretensão de correção, consegue realizar uma aproximação de uma fundamentação racional em uma realidade fática do “ser” extremamente mais complexa do que o “dever-ser”.
TERRITORIALIZAÇÃO DA AÇÃO PÚBLICA NO MEIO OESTE CONTESTADO: UMA FERRAMENTA PARA O ENFRENTAMENTO DA POBREZA?
Authors: Tecchio Andréia , Cazella Ademir Antonio
Published: June 2021

O Brasil inovou ao territorializar a ação pública de enfrentamento da pobreza com a criação do Programa Desenvolvimento Sustentável dos Territórios Rurais (Pronat) em 2003 e do Programa Território da Cidadania (PTC) em 2008. A ação pública territorializada busca a aplicação articulada de um conjunto de políticas públicas num território para tratar de forma diferenciada determinados segmentos sociais, tendo sua gestão compartilhada por atores da sociedade civil e do Estado. A partir dessa perspectiva, este artigo analisa os entraves e as potencialidades do Pronat e do PTC no enfrentamento da pobreza no Território Meio Oeste Contestado, composto por 29 municípios da região Oeste de Santa Catarina. Para tanto, realizou-se pesquisa documental e de campo em dez municípios, na qual foram entrevistados 38 atores institucionais. Os resultados indicam que a territorialização da ação pública não foi acompanhada de uma ferramenta de planejamento das ações de enfrentamento da pobreza. O Pronat beneficiou agricultores familiares ligados a movimentos sociais e sindicais do campo e inseridos em cadeias de comercialização. O PTC melhorou as condições de vida das populações pobres, todavia, não foi suficiente para fazer com que superassem a condição de pobreza. A extinção do Ministério do Desenvolvimento Agrário em 2016 implicou na descontinuidade desses programas, mas o aprendizado social da sua implementação pode embasar futuras ações públicas de desenvolvimento territorial com foco no enfrentamento da pobreza rural.
PERFIL SOCIOECONÔMICO DOS TITULARES DE AGROINDÚSTRIAS FAMILIARES NO OESTE DO PARANÁ

Published: June 2021

Este trabalho consiste em um estudo exploratório descritivo de um conjunto de 35 agroindústrias de 8 municípios do Oeste do Paraná, obtidos por uma empresa de assessoramento técnico na região, relacionados aos aspectos socioeconômicos dos titulares destas agroindústrias. Uma revisão bibliográfica contribuiu na análise e apresentação dos resultados estudados. O uso de uma matriz para tomada de decisão possibilitou identificar a ordem de prioridade de iniciativas, tanto de políticas públicas quanto dos proprietários dos empreendimentos agropecuários viabilizando, ações para melhorar a atratividade desses empreendimentos com rentabilidade e bem-estar dos proprietários. Identificou-se que 15 agroindústrias familiares possuem apenas dois membros na propriedade e 09 possuem apenas 03 membros, totalizando um percentual de 68,6% da amostra. A agroindústria contrata mão de obra terceirizada, mas identificou-se que apenas 22,9% faz uso dessa mão de obra. Há uma pequena predominância masculina na atividade. Quanto à matriz aplicada, os resultados ordenam a priorização de ações a serem desenvolvidas por meio de políticas públicas e/ou dos agricultores familiares para potencializar estabilidade e rendimentos em seus empreendimentos.
AQUICULTURA NA REGIÃO DE LARANJEIRAS DO SUL, PARANÁ: DIAGNÓSTICO E POLÍTICAS PÚBLICAS

Published: June 2021

Aquicultura tem crescido constantemente no Brasil e no Paraná, apresentando-se como oportunidade de diversificação da produção rural e geração de renda, sem aumento de mão de obra. No entanto, a atividade está pouco estruturada, com poucos estudos realizados sobre sua situação, viabilidade e caminhos para o desenvolvimento sustentável na região estudada. Objetivou-se com este trabalho diagnosticar a situação da aquicultura na região geopolítica de Laranjeiras do Sul – Paraná. A pesquisa é um estudo transversal descritivo baseado em entrevistas com questionário semiestruturado in loco em todas as entidades envolvidas no setor aquícola e em amostra aleatória de 70 de 190 aquicultores existentes, proporcionalmente, nos dez municípios avaliados. Dados foram submetidos ao teste qui-quadrado, nos softwares R e Sphinx. Entre entidades, observou-se que a maioria desconhece a cadeia, realizou projetos pontuais e sem continuidade, mas consideram alto o potencial de desenvolvimento. A maioria das políticas públicas até o momento buscaram apoiar o aquicultor na assistência técnica e construção de viveiros. O foco da produção apontou a venda direta e autoconsumo, havendo abate informal. Propriedades são majoritariamente pequenas, com outra atividade como principal, pequena lâmina de água, mão de obra predominantemente familiar e chefiadas por homens. A produção principal é de tilápia em policultivo semi-intensivo. Parte significativa relatou problemas na venda e entrega produção diretamente ao consumidor. Conclui-se que os principais problemas são: acesso a mercados, falta de abatedouros ou frigoríficos regularizados e assistência técnica. Considera-se que, solucionando-se estes, a aquicultura na região tem potencial de crescimento e pode representar forma de diversificação.
La Universidad en su redefinición epistemológica institucional
Authors: Cortez Schall Carolina
Published: June 2021

En este ensayo se aborda, como objeto de estudio, la definición de la Universidad Argentina y sus funciones desde sus orígenes, a través de una mirada analítica, focalizada en la transformación de la ciencia, la tecnología y su vínculo con el medio socio-productivo. Para luego concluir sobre las situaciones sociales emergentes que establecen la redefinición de las funciones de la universidad, visibilizadas en sus políticas, estrategias y prácticas concretas; en primer lugar,enlazadas a resolver las problemáticas sociales, para luego llegar al sector productivo y económico de un país.Frente a una transformación continua y dinámica de las estructuras configurantes de la universidad que se conoce, se evidencia un proceso de constantes cambios sociales y culturales, los cuales demandan otras funciones y acciones de las instituciones enmarcadas en un contexto político, social y económico; en medio de este, indefectiblemente la universidad, además de buscar su propio financiamiento, debe vincularse por medio de la empatía y la responsabilidad social. 

La situación emergente que se suscita, de una profunda crisis social, económica y sanitaria, lleva ante la inminente necesidad de pensar y repensar en la generación de políticas desde la gestión universitaria, que le ofrezcan centralidad y sustento al conocimiento para el desarrollo y el acompañamiento actual y futuro de la sociedad. Todo esto, por medio de la innovación, la tecnología y la transferencia de la ciencia de la mano con el medio socio productivo desde una profunda convicción de responsabilidad y calidad social universitaria.

Desafíos para la formación de docentes en matemática en Costa Rica
Authors: Sánchez-Ávila Alejandra
Published: June 2021

La reforma curricular de 2012 para la enseñanza y el aprendizaje de la matemática en Costa Rica a nivel de primaria y secundaria produjo cambios en algunos de los planes de formación de las personas docentes. Además, las últimas investigaciones realizadas para los Informes del Estado de la Educación señalan carencias en las prácticas de matemática en el aula. Durante la pandemia del virus responsable de la COVID-19, se evidencian debilidades para la atención del estudiante en modalidad a distancia y virtual. Por estas razones, se plantean cuatro retos que proponen una nueva revisión de estos planes de estudio por parte de las universidades desde la formación inicial del profesorado en esta asignatura.

Authors: Fauzi Fitriya , Antoni Darius , Suwarni Emi
Published: June 2021

This study aims to map the potential sectors based on the financial and digital literacy of women entrepreneurs in the city of Palembang, Indonesia, which continues from the previous research by Fauzi, Antoni, and Suwarni (2020). The research sample is small and medium businesses owned and managed by women entrepreneurs in Palembang where there are 18 districts. The research sample is selected from 18 districts in the city of Palembang and the total sample used is 115 women entrepreneur respondents. Descriptive statistics is employed in this study to map potential sectors and the results show that most businesses in Palembang are businesses engaged in the food, beverage, and tobacco industry, which account for 44.9%, while businesses engaged in other processing sectors rank second among the micro and small businesses in Palembang. Local and provincial governments can be more responsive to stimulate the food, beverage, and tobacco industry sector, other processing industry sectors and the wood industry sector, and wood furniture products so that products in the industrial sector can be superior in the future. The provision of coaching and training must also be more intensively provided by the relevant agencies so that they can help micro, small and medium enterprises (MSMEs) to develop in the future.
Accept. Understand. Then play! The impact of sport and physical activity in autism spectrum disorder
Authors: Sorgente Vincenzo , Cohen Erez James , Bravi Riccardo , Minciacchi Diego
Published: June 2021

Participating in sports and physical activity has physical,
psychological, cognitive and social benefits for everyone, including
young people with autism spectrum disorder (ASD). The practice
environment and instructorship are significant inclusion factors for
young people with ASD. A safe, attractive and easy-to-access environment
has a positive impact on the practice of physical activity for all
disabilities, ASD included. Nonetheless, the teachers and coaches are
not always informed of the condition of the young people for which they
are responsible and they may not have been trained to adapt their
coaching to the reality of these young people. They may not have the
knowledge, openness or resources to properly integrate a person with ASD
in their group. Hence, it is relevant to give them tools so they can
intervene more adequately with people living with ASD.

Published: June 2021

Bacteriophage is considered an alternative to antibiotics and
environmentally friendly approach to tackle antimicrobial resistance
(AMR) in aquaculture. Here, we reported isolation, morphology and
genomic characterizations of a newly isolated lytic bacteriophage,
designated pAh6.2TG. Host range and stability of pAh6.2TG in different
environmental conditions, and protective efficacy against a pathogenic
multidrug-resistant (MDR) Aeromonas hydrophila in Nile tilapia
were subsequently evaluated. The results showed that pAh6.2TG is a
member of the family Myoviridae which has genome size of 51,780
bp, encoding 65 putative open reading frames (ORFs), and is most closely
related to Aeromonas phage PVN02 (99.33% nucleotide identity).
The pAh6.2TG was highly specific to A. hydrophila and infected
83.3% tested strains of MDR A. hydrophila (10 out of 12) with
relative stability at pH 7 ­ 9, temperature 0 ­ 40 C
and salinity 0 ­ 40 ppt. In experimental challenge, pAh6.2TG treatments
significantly improved survivability of Nile tilapia exposed to a lethal
dose of the pathogenic MDR A. hydrophila, with relative percent
survival (RPS) of 73.3% and 50% for phage multiplicity of infection
(MOI) 1.0 and 0.1, respectively. Significant reduction of bacterial
counts in rearing water at 3 h (6.7 ± 0.5 to 18.1 ± 6.98 folds) and in
fish liver at 48 h post-treatment (2.7 ± 0.24 to 34.08 ± 26.4 folds) was
observed in phage treatment groups while opposite pattern for bacterial
counts was observed in untreated control. Interestingly, the surviving
fish provoked specific antibody (IgM) against the challenged A.
hydrophila. These results might explain the higher survival in phage
treatment groups. In summary, the findings suggested that the lytic
bacteriophage pAh6.2TG is an effective alternative to antibiotics to
control MDR A. hydrophila in tilapia and possibly other
freshwater fish.
Loading regulation prevents phloem failure during drought and widens the range of phloem and stomatal traits
Authors: Stanfield Ryan , Bartlett Megan
Published: June 2021

Plant carbon transport is controlled by a multitude of parameters both
internal and external to the sugar transporting phloem tissue. Sucrose
transporter kinetics, conduit hydraulic resistance, and xylem water
stress are all hypothesized to impact the amount of carbon delivered to
sink tissues. However, the most important traits determining carbon
export under drought are not well understood, especially for species
with active molecular regulation of sucrose transport. This in turn
limits our ability to assess species’ resistances to phloem dysfunction
under drought. Here, we use an integrated xylem-phloem-stomatal model to
calculate leaf water potential from soil dryness, which is then used to
determine gas exchange and phloem pressure gradients. We quantitatively
compare the impacts of phloem loading kinetics, including feedbacks
between loading and phloem pressure, phloem conduit resistances, and
stomatal responses to water stress, on the total carbon export to sinks
during drought. Regulating sucrose transporter kinetics which
downregulates loading at high phloem pressures prevented runaway
viscosity in the phloem sap and was the most important determinant of
export rates under drought. In contrast to previous models, we found
this feedback mechanism decoupled stomatal traits from phloem export
efficiency during drought and increased the operational range of phloem
hydraulic resistances.
Toll-Like Receptor 2 (TLR2) Knockout Abrogates Diabetic and Obese Phenotypes While Restoring Endothelial Function via Inhibition of NOX1
Authors: Guo Zhen , Zhang Yixuan , Liu Chang , Youn Ji Youn , Cai Hua
Published: June 2021

We have previously demonstrated a novel role of bone morphogenic protein 4 (BMP4) in inducing NOX1-dependent endothelial nitric oxide synthase (eNOS) uncoupling, endothelial dysfunction, and inflammatory activation in type 2 diabetes mellitus (T2DM). However, how BMP4 activates NOX1 and whether targeting the new mechanistic pathway revealed is effective in preserving endothelial function in T2DM remains unclear. In this study, we observed that BMP4 induced a marked, time-dependent increase in physiological binding between TLR2 and NOX1 in aortic endothelial cells as well as increased binding of TLR2 to NOXO1. In TLR2 knockout (Tlr2−/−) mice fed high-fat diet, body weight gain was significantly less compared with wild-type (WT) mice both in males and females. The high-fat diet–induced increases in fasting blood glucose levels, as well as in circulating insulin and leptin levels, were absent in Tlr2−/− mice. High-fat feeding induced increases in overall fat mass, and in fat mass of different pockets were abrogated in Tlr2−/− mice. Whereas energy intake was similar in high-fat–fed WT and Tlr2−/− mice, TLR2 deficiency resulted in higher energy expenditure attributable to improved physical activity, which was accompanied by restored skeletal muscle mitochondrial function. In addition, TLR2 deficiency recoupled eNOS, reduced total superoxide production, improved H4B and NO bioavailabilities in aortas, and restored endothelium-dependent vasorelaxation. Collectively, our data strongly indicate that TLR2 plays important roles in the development of metabolic features of T2DM and its related endothelial/vascular dysfunction. Therefore, targeting TLR2 may represent a novel therapeutic strategy for T2DM, obesity, and cardiovascular complications via specific inhibition of NOX1.
Differences in U.S. Rural-Urban Trends in Diabetes ABCS, 1999–2018

Published: June 2021

OBJECTIVE

To examine changes in and the relationships between diabetes management and rural and urban residence.

RESEARCH DESIGN AND METHODS

Using National Health and Nutrition Examination Survey (1999–2018) data from 6,372 adults aged ≥18 years with self-reported diagnosed diabetes, we examined poor ABCS: A1C >9% (>75 mmol/mol), Blood pressure (BP) ≥140/90 mmHg, Cholesterol (non-HDL) ≥160 mg/dL (≥4.1 mmol/L), and current Smoking. We compared odds of urban versus rural residents (census tract population size ≥2,500 considered urban, otherwise rural) having poor ABCS across time (1999–2006, 2007–2012, and 2013–2018), overall and by sociodemographic and clinical characteristics.

RESULTS

During 1999–2018, the proportion of U.S. adults with diabetes residing in rural areas ranged between 15% and 19.5%. In 1999–2006, there were no statistically significant rural-urban differences in poor ABCS. However, from 1999–2006 to 2013–2018, there were greater improvements for urban adults with diabetes than for rural for BP ≥140/90 mmHg (relative odds ratio [OR] 0.8, 95% CI 0.6–0.9) and non-HDL ≥160 mg/dL (≥4.1 mmol/L) (relative OR 0.45, 0.4–0.5). These differences remained statistically significant after adjustment for race/ethnicity, education, poverty levels, and clinical characteristics. Yet, over the 1999–2018 time period, minority race/ethnicity, lower education attainment, poverty, and lack of health insurance coverage were factors associated with poorer A, B, C, or S in urban adults compared with their rural counterparts.

CONCLUSIONS

Over two decades, rural U.S. adults with diabetes have had less improvement in BP and cholesterol control. In addition, rural-urban differences exist across sociodemographic groups, suggesting that efforts to narrow this divide may need to address both socioeconomic and clinical aspects of care.

Published: June 2021

Purpose. The purpose of the research is to analyze Ukraine and its enterprise’s methods of implementation of circular principles and business models to ensure their sustainable development. Design/methodology/approach. The study examines the hypothesis of the global need and high efficiency of changing the economic model from linear to circular at different levels, including the adaptation of circular business models at Ukrainian enterprises. To assess the essence, advantages, practical approaches, and examples of transformation by enterprises of the circular principles and business models, general scientific theoretical methods of scientific research (formalization, analysis, and synthesis, systematization, and explanation) are used. Findings. The hypothesis of the global need and high efficiency of changing the economic model from linear to circular at different levels, including the adaptation of circular business models at Ukrainian enterprises, is proven. The world experience and practice, first of all, European, are analyzed, and successful examples of their introduction by the leading enterprises are given. They confirmed that circular principles are helpful not only for ecology and the environment but also for enterprises and states’ economic efficiency. Practical implications. The results of this research show that taking into account the world experience and provided recommendations, in particular on “green procurement”, it is expedient for domestic enterprises to implement promptly circular business models for sustainable development and international competitiveness boosting, and for the state – to develop a clear strategy for transition to a circular economic model. For its effective implementation, it is necessary to consider three aspects: economic, environmental, and social, as well as possible risks. Originality/value. Considering current environmental and economic problems, the circular model was recognized as especially relevant for Ukraine today on its way to the E.U. This study highlights the essence, principles, prerequisites, and world experience of transition from a linear to a circular model of the economy and ways of sustainable development and competitiveness of domestic enterprises by adapting circular business models. The results are valuable for enterprises and countries in their transition to circularity, providing waste recovery and recycling, using renewable materials and reuse of products, prevention of pollution and depletion of resources, ensuring profitability and sustainable development.

Calcium oxalate is one of the most common components in urolithiasis. Its treatment includes the use of synthetic drugs, ultrasound and surgery. However, cheaper alternative treatment using herbal medicine with less adverse side effect is preferred. Essential oils from Thai basil (Ocimum bacilicum L.), Vietnamese coriander (Persicaria odorata) and Chinese parsley (Coriandum sativum L.) were extracted and investigated for antiurolithic activity based on calcium oxalate crystallisation. Most of the crystals formed in control sample were hexagonal calcium oxalate monohydrate with sizes ranging between 3 to 4 m. The size of the crystals was found to be slightly reduced in O. bacilicum oil (2-4 m) at high concentration with less aggregation of crystals. Samples with P. odorata oil gave smaller crystal size (3 m) mainly in dehydrate form and the oil was also found to inhibit the aggregation of the crystals at high concentration. C. sativum oil enhanced crystallisation (5-6 m) with increased concentration and showed high aggregation of the crystals. This preliminary study shows the therapeutic potential of these medicinal plants to be used in traditional anti-urolithic therapy.

Etlingera coccinea, a native Borneon Zingiberaceae are found to exert allelopathic effect on some weed species. The objective of this study is to investigate the allelopathic effects of hexane (80%), methanol (80%), ethyl acetate (80%) extracts from the dried powder of both stem and leaf of E. coccinea on mung bean (Vigna radiata) and Siam weed (Chromolaena odorata). The phytochemical screening of both stem and leaf crude extracts elicited saponin, tannin, flavonoid, and terpenoid, which are targeted bioactive compounds for allelopathy. The allelopathic activity was assessed by evaluating their effects on seed germination and percentage of radicle and shoot growth. The results showed that both stem and leaf extracts have a suppressive effect on the mung bean development during in-vitro bioassay. The methanolic extracts of both stem and leaf showed the most significant suppression (100%) than other solvent extracts. In the pot experiment, the methanolic stem extracts suppressed the Siam weed’s germination by 57 ± 0.13% and the methanolic leaf extracts suppressed the growth by 46 ± 0.29%. The present study shows that E. coccinea methanolic extract has the potential as bio-herbicide.

Polyaniline (PANI) and Kronos C doped Titanium dioxide (TiO2) was fabricated as PANI/TiO2 solar cell and reported on its simple photovoltaic performance detected by using voltameter and tested for stability for 12 months. The PANI and TiO2 were coated onto different indium tin oxide (ITO) glass plates by using a drop-casting method and sandwich attached for simple solar cell preparation. PT4 sample was the optimum solar cell with 0.2: 0.2 g of PANI: TiO2 ratio under 2 cm2 surface area based on the highest voltage produces from 100 mW cm-1 of light intensity metal highlight lamp. No voltage was detected for PT7 where the single layer TiO2 coated without PANI attached for solar cell system using same fabrication. It shows that PANI has a significant role in functionalizing the photovoltaic system. The C-N stretching of aromatic amine and C-N stretching for the benzenoid at peaks of 1222 and 1166 cm-1 respectively in FTIR spectra has confirmed the PANI structure supported by an XRD pattern. TP4 has the highest photovoltaic performance compared to other types of TiO2 based on the electron lifetime (τe) and the voltage produced was sustained up to 12 months.
Violencia sexual en el trabajo de campo: autoetnografía a dos voces
Authors: Romero Plana Virginia , Martínez Santamaría Luz
Published: June 2021

Este artículo analiza, desde la crítica feminista y decolonial, la violencia sexual hacia las mujeres durante la formación universitaria y particularmente en el trabajo de campo, como un aspecto microsocial de la estructura patriarcal y de las desigualdades sufridas por las mujeres. Desde un enfoque autoetnográfico, a partir del relato de nuestras experiencias de violencia sexual, identificamos cómo opera la violencia de género en el trabajo de campo y rescatamos las respuestas a nuestras denuncias y el impacto en nuestras vidas y trayectorias académicas. Ante la falta de preparación de las universidades para hacer frente a este problema se concluye que es urgente generar un diálogo entre instituciones educativas y voces feministas para reconocer y eliminar la violencia de género.
Az iskolai egészségfejlesztés hazai és nemzetközi szemléletének bemutatása
Authors: Járomi Éva , Vitrai József
Published: June 2021

Háttér: A magyar lakosság egészsége elmarad az EU fejlettebb tagországaihoz képest. Az egészségveszteségek döntően a viselkedéssel összefüggő kockázatokra vezethetők vissza. A gyermekkorban kialakított egészségmagatartás kulcsszerepet játszik a lakosság egészségének javításában. A közlemény célja az iskolai egészségfejlesztés egyes megközelítéseinek bemutatása valamint az esetlegesen fennálló (szemléletbeli) különbségek okainak feltárása. Ezt követően pedig új fejlesztési lehetőségek bemutatása, majd ezek alapján ajánlások megfogalmazása a szakemberek és döntéshozók számára. Módszer: Hazai és nemzetközi adatbázisok (MATARKA és PubMed, ScienceDirect, Cochrane Library) alapján szakirodalmi áttekintés készítése. A szakirodalmi keresés a következő kulcsszavas kereséssel történt: iskolai egészségfejlesztés, egészségfejlesztő iskola, iskolai beavatkozások, szervezeti beavatkozás, komplexitás, teljes körűség, rendszer, valamint ezek angol nyelvű megfelelői. Eredmények: Alapvető szemléletmódbeli különbségek figyelhetőek meg az egészségfejlesztésben élenjáró országok és Magyarország között. Míg hazánkban az egészségfejlesztés elszigetelve, az egészségügy peremére szorulva tevékenykedik, addig a kedvezőbb egészségügyi mutatókkal rendelkező államokban (pl. az Egyesült Királyság, Kanada) az egészségfejlesztés egy sokszereplős, interszektoriális rendszerben működik. Azokban az országokban részvételen alapuló, koordinált, komplex adaptív rendszerként tekintenek az egészségfejlesztésre, mely a helyi közösségbe ágyazva, integráltan működik. Más megközelítések szerint az egészségmagatartás, mint az elhízást eredményező egészségtelen táplálkozás kulturálisan befolyásolt, komplex probléma. Feltételezhető, hogy az egészségfejlesztési törekvések, mint pl. az elhízás visszaszorításának sikertelenségét egyfajta „ördögi kör” magyarázza: egy adott közösség kultúrája egyben akadálya is a kultúra megváltoztatásának. Következtetések: A hazai iskolai egészségfejlesztés teljes körűségét előíró jogi szabályozások önmagukban nem elegendőek a köznevelési intézmények egészségfejlesztési tevékenységeinek hatékony megvalósításához. Az iskolai színtéren történő egészségfejlesztés kitörési pont lehet. A hatékony egészségfejlesztéshez komplex megközelítésre van szükség, azaz a társadalmi szereplők különböző szinten megvalósuló, összehangolt tevékenységére. A járási szinten előírt közösségi egészségtervezés lehetőséget kínál a komplex iskolai egészségfejlesztés Magyarországon történő megvalósítására.
A leggyakoribb nemi betegségekre vonatkozó ismeretek középiskolai pedagógusok számára I. rész
Authors: Burián Katalin , Spengler Gabriella

A nemi betegségekről, a terjedési módokról, a betegséget kiváltó kórokozókról a szexuális élet megkezdése előtt a fiataloknak megfelelő tudásanyaggal kellene rendelkezniük. A téma viszont rendkívül kényes, nehéz beszélni róla, még a harmonikus családban élő fiatalok számára is. Az iskolai biológia- és egészségtanórák tempója is meglehetősen feszes, így ez a témakör kevésbé ismert fiatalok között. A szerzők a rendszertani kategóriákat követve (vírusok, baktériumok, gombák, véglények) bemutatják azokat a Magyarországon gyakrabban előforduló mikroorganizmusokat, amelyek nemi betegséget okozhatnak. Ismertetésre kerülnek a különböző nemi betegségeket kísérő tünetek és panaszok, amelyek felhívják a fertőzött személy figyelmét a betegségre. Ahhoz, hogy ezek a betegségek elkerülhetők legyenek, a fiataloknak tudatában kell lenniük, hogy ezek a kórokozók nemcsak az intim szexuális együttlét során, hanem a szexuális szokásoktól függően nyálkahártyán keresztül, akár orálisan is terjedhetnek. Fontos arról is tudni, hogy ezek a mikroorganizmusok mennyire ellenállóak a környezetükben, számíthatnak-e fertőzésre uszodában vagy mellékhelységben. A téma megismertetésében a szakemberek segítsége a biológiatanárok és a tanulók részére tartott iskolai előadások keretében sokat javíthatna.
Az egészség ökoszociális elmélete
Authors: Csizmadia Péter
Published: June 2021

Az ökoszociális egészségmodell az emberre ható jelenségek egymással minden szinten való egybefonódását hangsúlyozza. Kiemeli, hogy az egészséget meghatározó egyéni tényezőket – leszámítva az öröklött tulajdonságokat – jórészt a környezeti tényezők befolyásolják, és ezek között is a társadalmi-gazdasági-politikai körülmények azok, amelyek, mint az „okok okai” valamennyi tényezőre hatással vannak. Kiemeli, hogy az egyének önkárosító magatartását is a külső környezet döntően meghatározza. Emiatt a kockázati egészségmagatartás visszaszorítása is csakis a társadalmi-gazdasági-politikai környezet megfelelő változtatása révén lehet sikeres
Effects of potential confounding variables on accuracy of a commercially available veterinary point-of-care hematocrit meter in the evaluation of blood samples from dogs and cats
Authors: Thevelein Britt A. L. , Koenig Amie , Brainard Benjamin M. , Lane Selena L.
Published: June 2021

OBJECTIVE

To assess the agreement in measurements of Hct values and hemoglobin (Hgb) concentrations in blood samples from dogs and cats between a commercially available veterinary point-of-care (POC) Hct meter and a laboratory-based (LAB) analyzer and to determine the effects of various conditions (ie, lipemia, hyperbilirubinemia, hemolysis, autoagglutination, and reticulocytosis) on the accuracy of the POC meter.

SAMPLES

Blood samples from 86 dogs and 18 cats

PROCEDURES

Blood samples were run in duplicate on the POC meter, which reported Hgb concentration, measured via optical reflectance, and a calculated Hct value. The POC meter results were compared with results from a LAB analyzer. Blood samples with grossly visible lipemia, icterus, hemolysis, and autoagglutination were noted.

RESULTS

Mean ± SD values for LAB Hct were 33.9 ± 15.73% (range, 3.9% to 75.8%), and for LAB Hgb were 11.2 ± 5.4 g/dL (range, 1 to 24.6 g/dL). Mean bias between POC Hct and LAB Hct values was–1.8% with 95% limits of agreement (LOAs) of–11.1% to 7.5% and between POC Hgb and LAB Hgb concentrations was–0.5 g/dL with 95% LOAs of–3.8 to 2.8 g/dL. There was no influence of lipemia (14 samples), icterus (23), autoagglutination (14), hemolysis (12), or high reticulocyte count (15) on the accuracy of the POC meter. The POC meter was unable to read 13 blood samples; 9 had a LAB Hct ≤ 12%, and 4 had a LAB Hct concentration between 13% and 17%.

CONCLUSIONS AND CLINICAL RELEVANCE

Overall, measurements from the POC meter had good agreement with those from the LAB analyzer. However, LOAs were fairly wide, indicating that there may be clinically important differences between measurements from the POC meter and LAB analyzer. (J Am Vet Med Assoc 2021;259:49–55)
Role of an ABCB1 1930_1931del TC gene mutation in a temporal cluster of macrocyclic lactone–induced neurologic toxicosis in cats associated with products labeled for companion animal use
Authors: Mealey Katrina L. , Burke Neal S. , Connors Rebecca L.
Published: June 2021

OBJECTIVE

To determine whether ABCB11930_1931del TC predisposed cats to macrocyclic-lactone toxicosis and the frequency of the ABCB11930_1931del TC gene mutation in banked feline DNA samples.

SAMPLE

DNA samples from 5 cats presented for neurologic clinical signs presumed to be caused by exposure to macrocyclic lactones and 1,006 banked feline DNA samples.

PROCEDURES

The medical history pertaining to 5 cats was obtained from veterinarians who examined, treated, or performed necropsies on them. The DNA from these 5 cats and 1,006 banked feline samples were analyzed for the presence of the ABCB11930_1931del TC genotype.

RESULTS

4 of the 5 cats with neurologic signs presumed to be associated with macro-cyclic-lactone exposure were homozygous for ABCB11930_1931del TC. The other cat had unilateral vestibular signs not typical of macrocyclic-lactone toxicosis. The distribution of genotypes from the banked feline DNA samples was as follows: 0 homozygous for ABCB11930_1931del TC, 47 heterozygous for ABCB11930_1931del TC, and 959 homozygous for the wild-type ABCB1 allele. Among the 47 cats with the mutant ABCB1 allele, only 3 were purebred (Ragdoll, Russian Blue, and Siamese).

CONCLUSIONS AND CLINICAL RELEVANCE

Results suggested a strong relationship between homozygosity for ABCB11930_1931del TC and neurologic toxicosis after topical application with eprinomectin-containing antiparasitic products labeled for use in cats. Although this genotype is likely rare in the general cat population, veterinarians should be aware of this genetic mutation in cats and its potential for enhancing susceptibility to adverse drug reactions.
