Abstract Background Acne is a chronic inflammatory disorder of the pilosebaceous unit that is associated with a negative impact on quality of life, causing anxiety, depression, and poor self-esteem. The treatment of acne is not simple and presents some new challenges. This article addresses important issues faced by dermatologists on their daily, some of them specific for Latin America. Objective To discuss daily practice recommendations when managing acne patients. Methods A literature review was conducted by a group of eight experts with extensive experience in the field of acne. The results of the data review were presented at an initial kick-off meeting to align the consensus topics. Two e-surveys using the Delphi methodology and an interim group webinar meeting were held. Results The expert panel reached a consensus on all proposed key statements, providing scientific support to help dermatologists and healthcare providers make acne management decisions on topics that can be challenging in the everyday practice of dermatology, such as the characteristics of Generation Z or the importance of the maintenance phase of adult acne treatment. Conclusion This article provides current recommendations for managing acne patients. The high level of agreement achieved based on the latest evidence supports the best acne therapeutic choices in both established topics and new important issues that have emerged in recent years, such as the impact of social media, Generation Z characteristics, and transgender male patient specifics.

ABSTRACT Objective To evaluate the in vitro and in vivo toxicities of polyethylene glycol-coated gold nanoparticles synthesized using a one-step process. Methods Gold nanoparticles were prepared via a co-precipitation method using polyethylene glycol, and the synthesis product was characterized. For the in vitro evaluation, a flow cytometry analysis with Annexin V and iodide propidium staining was used to assess cytotoxicity in MG-63 cells labeled with 10, 50, and 100µg/mL of nanoparticle concentration. For the in vivo evaluation, nanoparticles were administered intraperitoneally at a dose of 10mg/kg dose in 10-week-old mice. Toxicity was assessed 24 hours and 7 days after administration via histopathological analysis of various tissues, as well as through renal, hepatic, and hematopoietic evaluations. Results Synthesized nanoparticles exhibited different hydrodynamic sizes depending on the medium: 51.27±1.62nm in water and 268.12±28.45nm (0 hour) in culture medium. They demonstrated a maximum absorbance at 520nm and a zeta potential of -8.419mV. Cellular viability exceeded 90%, with less than 3% early apoptosis, 6% late apoptosis, and 1% necrosis across all labeling conditions, indicating minimal cytotoxicity differences. Histopathological analysis highlighted the accumulation of nanoparticles in the mesentery; however, no lesions or visible agglomeration was observed in the remaining tissues. Renal, hepatic, and hematopoietic analyses showed no significant differences at any time point. Conclusion Polyethylene glycol-coated gold nanoparticles exhibit extremely low toxicity and high biocompatibility, showing promise for future studies.

Capillary electrophoresis (CE) methods have unique potential for applications in quality control of pharmaceutical formulations. Here, we show that a single and ultra-fast CE method can be used for the determination of hydrochlorothiazide (HCT) in combination with nine other active ingredients in a single run in different pharmaceutical samples: atenolol (ATE), metoprolol (MET), propranolol (PRO), benazepril (BEN), captopril (CAP), enalapril (ENA), lisinopril (LIS), ramipril (RAM), and valsartan (VAL). This goal was achieved using a single and simple background electrolyte (BGE) composed of 10 mmol L-1 of boric acid with pH adjusted to 9.0 with sodium hydroxide. All samples can be analyzed in less than 1 min with the attainment of good analytical performance, such as high-resolution separation (r > 1.3), low sample and reagents consumption (environmentally friendly method), low relative standard deviation (RSD) values for peak area (< 4.0%) and migration times (< 1.7%), and linear relationships with good correlation coefficients (> 0.995). Furthermore, recovery tests showed good results (100 ± 5%) for all evaluated compounds.

RESUMO Este artigo teve como objetivo compreender os Determinantes Sociais da Saúde (DSS), em área periférica de uma capital brasileira, sob a perspectiva de atores sociais e políticos da região. Baseou-se na abordagem qualitativa, com 45 participantes, entre trabalhadores do setor saúde; de sede administrativa regional; vereadores, líderes religiosos e representantes de entidades organizadas do Grande Bom Jardim, Fortaleza (CE). Utilizou-se de análise documental, de grupo focal e de entrevista semiestruturada. Realizou-se análise de conteúdo, englobando as categorias dos DSS e os temas gerais ‘dentro e fora de casa’, analisados com base nas representações sociais. As mudanças positivas se evidenciaram no tema ‘dentro das casas’ dos moradores: alimentação, melhorias advindas de benefícios da política de assistência social, aumento do abastecimento de água e de energia elétrica. No tema ‘fora das casas’, a influência negativa na saúde destacou-se com baixo índice de cobertura de saneamento básico, insuficiência na oferta de transporte público e insegurança. Propõe-se a inclusão de temas sobre segurança, energia elétrica, mobilidade urbana, assistência social e saneamento básico para subsidiar novos estudos sobre determinação social e elaboração de medidas que contribuam para a promoção da saúde e equidade social nos territórios urbanos.

Tratando sobre las extravagancias de la referencia, Quine estudia la vaguedad, ambigüedad y opacidad de los términos. Las reflexiones que siguen pretenden centrarse fundamentalmente en la ambigüedad; pero para ello creí oportuno aclarar conceptos en torno a la vaguedad, como introducción casi necesaria aI tema

Desde la primera página, Katz plantea eI problema – que estudiará desde distintos puntos de vista a to largo de toda la obra –,1 de la necesidad de no detener se en una lógica de nivel sintáctico, y de pasar al plano de la lógica semántica, si queremos demostrar la validez de muchos argumentos que, de otro modo, quedarían sin explicaci6n consecuencial

O autor inicia seu estudo com a colocação do postulado da Lógica Moderna segundo o qual apenas as proposições particulares apresentam conteúdo existencial. Essa posição indica, segundo o autor, confusão entre conclusões demonstradas e postulados. Os medievais também partiram de posição semelhante e constroem a Lógica partindo do postulado de que somente as proposições afirmativas apresentam conteúdo existencial e não as negativas. Pretende o autor demonstrar a congruência do postulado da Lógica medieval, estudando especialmente Alberto de Saxônia, sem a pretensão de refutar a Lógica Moderna, mas recusando a exigência moderna da cláusula existencial já prevista no postulado medieval.

Introduction: The rights of social protection policies for children and youth need to be discussed for their strengthening to guarantee universality or to create new forms of that policies. Method: Documentary review supported by content analysis techniques and interpretive analysis of four social protection systems for children and youth: integral social security, family subsidy, social assistance, and the national system of family welfare. For the analysis, theoretical-political references to universal social protection and the doctrine of the protection of the rights of children and young people were considered. Results: The social protection systems analyzed are described in terms of implementation mechanisms, participation of children and youth criteria, financing, and rectory. The life course approach and its universality, institutional appropriation, and participation of children and young people were discussed. Conclusion: The social protection systems analyzed show social protection strategies for children and young people within the framework of the Social Constitutional State, but they are implemented through welfare, compensatory and targeted policies that contrast the perspectives of needs with that of the protection of children’s rights, and provide insufficient support for the principles of equality, participation, and universality.

Este trabajo tiene como objetivo desvelar la forma en la que se representa la edad a través de los personajes en la película La flor de mi secreto (Pedro Almodóvar, 1995) En particular, a través del personaje de Leo Macías —y su alter ego literario, Amanda Gris—, su hermana Rosa y Jacinta, la madre de ambas. Se pretende analizar las motivaciones del cineasta a la hora de tratar la edad e identificar las aportaciones de Almodóvar como creador a esta realidad social y determinar la posible correlación con la propia experiencia vital del director. Se optará por una metodología basada en el análisis de personajes (Chatman, Casetti y Di Chio, Pérez Rufi; Guarinos) complementada con la idea del conflicto de Seger, aplicable al personaje de Leo Macías y un marco teórico fundamentado en la Teoría Fílmica Feminista (Colaizzi), la Teoría Queer (De Lauretis) así como trabajos sobre estudios etarios en el audiovisual (Zurian, Menendéz y García-Ramos). Se demuestra que La flor de mi secreto plantea una ruptura con los patrones sociales establecidos con la representación de la vejez en la mujer a través de las expectativas de vida de personajes en los que Almodóvar se autorrepresenta y autorreferencia.

Este trabajo analiza los procesos de manumisión de esclavos que se dieron en la provincia de Popayán entre 1821 y 1851. El estudio muestra que las élites esclavistas payanesas lograron obstaculizar los mecanismos dispuestos para liberar la mano de obra, especialmente antes de 1845. Las estrategias intentaron retardar el final del sistema esclavista e incluyeron la manipulación del marco legal, la exportación de esclavos, el entorpecimiento del funcionamiento administrativo de las juntas de manumisión cantonales y otras maniobras jurídicas para impedir la liberación de los esclavos a través de mecanismos ajenos a las juntas.

The objective of this study was to conduct a systematic review focused on studies that used micro-computed tomography (micro-CT) analysis to evaluate untouched canal areas after root canal preparation with continuous rotary and reciprocating kinematics. Electronic search strategies were used in LILACS, PubMed (MedLine), Science Direct, Cochrane, Scopus and Web of Science databases. An additional search for gray literature was performed on Google Scholar, OpenGrey and ProQuest. In addition, manual searches were performed on the reference list of included articles. It covered studies in English, Portuguese and Spanish, without restriction regarding the publication time. The articles selected for inclusion in this review meet all the following criteria: in vitro studies that evaluated, with the use of micro-CT, the percentage of untouched areas after root canal preparation comparing rotary and reciprocating kinematics. A total of 11 studies were selected for qualitative and quantitative analysis. One study showed that the Reciproc system has a smaller percentage of untouched channel walls in lower incisors when compared to BioRace system. Another study showed no significant differences between reciprocating systems Reciproc and WaveOne with BioRace in mesial root canals of lower molars. Similarly, they did not observe any difference between ProTaper Next and ProTaper Universal with WaveOne. A single study showed differences between XP-Endo Shaper system (rotary) compared with WaveOne Gold. The studies evaluated in the present review showed by micro-CT that none of the instrumentation systems, regardless of the kinematics used or NiTi heat treatment, was able to completely touch the root canal walls.

El objetivo de este artículo es explorar los efectos del contexto económico del país de residencia en la declaración de la intención de retorno entre los inmigrantes. Con base en los datos del Segundo Registro de Chilenos en el Exterior, este artículo establece un análisis multinivel de los determinantes de la intención de retorno entre emigrantes chilenos con más de 54 países diferentes. Se pretende entender cómo se articulan diversas variables explicativas en distintos niveles, es decir, en qué medida las características de los países de residencia de los emigrantes determinan la intención de retorno en relación con los factores vinculados con su trayectoria vital. La contribución de este artículo es mostrar que mientras los efectos del contexto económico no parecen ser significativos, las variables individuales, en cambio, demuestran tener un fuerte impacto, lo que resulta congruente con el resto de la literatura sobre la intención de retorno.

El Estado chileno ha desarrollado programas habitacionales destinados a dotar de viviendas a sectores de bajos ingresos en zonas rurales. Si bien estas soluciones constituyen un avance en las condiciones de vida de las familias, persisten aspectos por mejorar. Uno de estos se refiere a la coherencia entre los diseños de las viviendas y las características identitarias de los usuarios. El presente trabajo analiza la respuesta del Estado, a través de sus políticas habitacionales, a las necesidades del habitar del pueblo Mapuche-Pewenche, así como su cultura y forma de vida, entendidos estos como patrimonio material e inmaterial. El estudio se centra en los territorios cordilleranos de la comuna de Alto Biobío, ubicada en la región homónima, donde se encuentran asentadas las comunidades pewenches. La metodología utilizada involucra entrevistas a informantes claves, visitas a terreno y consultas a fuentes primarias y secundarias. Los resultados confirman que la política habitacional ha aportado mejores estándares tecnológicos y, con ello, mayor calidad de vida a las familias, que, en general, viven en condiciones de vulnerabilidad material. Sin embargo, a partir de la percepción de las comunidades, se evidencia que, aún cuando existen familias proclives a incorporar formas de vida ajenas, un número importante desea preservar su cultura, la que consideran amenazada por la imposición de formas de vida exógenas.

En este artículo se analizan las trayectorias de investigación de trabajadoras/es sociales chilenos, relevando una dimensión específica como foco interpretativo: la posicionalidad geopolítica que va dando forma a estas trayectorias, es decir, las complejas relaciones de poder que les posicionan en espacios de valor cambiante y frecuentemente contradictorio, marcados por las exigencias del capitalismo cognitivo. En base a las contribuciones de la teoría crítica, el pensamiento decolonial, perspectivas interseccionales, critical race theory y teorías de posicionamiento indígena, se analizan los resultados preliminares de una investigación cualitativa sobre trayectorias de investigación. Se identifican ciertos “marcadores” o jerarquías de opresión que dan forma a esta posicionalidad –clase, género, etnia, territorio, disciplina, entre otras- , las cuales configuran la posición que construyen las/os trabajadores sociales en su trabajo investigativo y los anclajes identitarios que dan sentido a la tarea de investigar en un escenario competitivo y regido por los criterios de la “economía del conocimiento”.

In this work, we present the most recent numerical results in a nodal approach, which resulted in the development of a new numerical spectral nodal method, based on the spectral analysis of the multigroup, isotropic scattering neutron transport equations in the discrete ordinates ($S_N$) formulation for fixed-source calculations in non-multiplying media (shielding problems). The numerical results refer to simulations of typical problems from the reactor physics field, in rectangular two-dimensional Cartesian geometry, $X, Y$ geometry, and are compared with the traditional Diamond Difference ($DD$) fine-mesh method results, used as a reference, and the spectral coarse-mesh method Green's function ($SGF$) results.

Cristina Rivera Garza’s (non) fiction trajectory is a dialogue of interests threaded by her passions for translation, history, poetics, among many other topics. In this article, Diamantina -- a repetitive character in the author’s corpora -- is traced to analyze how gender and cultural memory are portrayed in Nadie me verá llorar (1999) Ningún reloj cuenta esto (2002) and Dolerse: textos desde un país herido (2011). By commenting on Ramón López Velarde’s famous stanza “La patria es impecable y diamantina” in “Suave patria” (1921), Rivera Garza proposes an alternative way of performing nation by women who resist the virtuous adjectives exalted by Velarde in post-revolutionary Mexico, which can be threaded to the glitter used in recent public demonstrations against femicides and gender-based violence. Narrative memory is proposed to name the intersections of intertextuality and cultural memory in her literary cultural production that goes beyond the borders of a nation. This article centralizes the short-story, “La alineación también tiene su belleza” in Ningún reloj cuenta esto, which is set in San Antonio, Texas and New York City, to analyze Mexican canonical representations of women as Patria from a transnational lens.

La psicología del consumidor permite analizar las respuestas de los individuos ante diversas situaciones. El objetivo de este estudio es explorar los mecanismos de afrontamiento de la soledad generada por rupturas amorosas a la luz de la psicología del consumidor, con un enfoque centrado en las motivaciones de resolución de la situación de ruptura de manera no clínica y mediada por la dinámica de consumo de bienes o servicios reparadores. El estudio fue de tipo cualitativo, sobre diez entrevistas en profundidad a siete mujeres y tres hombres que experimentaron los efectos y las consecuencias de una ruptura amorosa en el último año. Se encontró que los afectados recurren a variadas formas de consumo como la música, libros de apoyo, actividades deportivas y de ocio, lo que les proporcionó maneras de pasar el tiempo, mantener la mente activa, tener interacción social para divertirse y reconectarse con amigos y familia, de tal forma que pudieron mejorar la relación consigo mismos en esa fase situacional de sus vidas. Se concluye que la mediación de actividades de consumo y el redescubrimiento de nexos sociales son fuentes importantes para reponerse de la ruptura amorosa. El estudio presenta limitaciones en cuanto al número de participantes, pero logrando saturación en la información obtenida.

A exportação de bovinos vivos é uma das novas áreas comerciais em que o Brasil está inserido, porém é necessário que os animais sejam livres de doenças infectocontagiosas, principalmente as exigidas pelos países importadores. Os 1800 soros utilizados neste estudo foram de bovinos dos Estados de Goiás (GO), Minas Gerais (MG) e São Paulo (SP), que seriam destinados à exportação. Foram realizados os diagnósticos sorológicos para brucelose bovina (BB), paratuberculose (PTB), leucose enzoótica bovina (EBL) e diarreia viral bovina (BVD), sendo este o primeiro trabalho no Brasil a realizar o levantamento sorológico para PTB em bovinos nos Estados de SP, GO e MG, e de BVD em GO. A porcentagem total de animais positivos para cada uma das patologias foi de 0,33% (2/1800) para BB; 16,17% (97/1800) para PTB; 31,50% (189/ 1800) para EBL e 9,67% (58/1800) para BVD.

A adaptação das espécies de Pleurotus a novos resíduos representa atualmente um dos principais processos de bioconversão de resíduos agroindustriais em produtos comestíveis de alto valor nutricional. Com o presente trabalho, utilizando-se do princípio das tecnologias limpas, cultivou-se a linhagem/lote EF-136B de Pleurotus ostreatus em bagaço de Bocaiúva suplementado com bagaço de cana-de-açúcar. A eficiência biológica (EB) obtida no Tratamento 1 (T1 - composto de 70% bagaço de cana e 30% do bagaço de Bocaiúva) foi de 30,81±9,23 e no Tratamento 2 (T2 - composto por 50% do bagaço de cana e 50% de bagaço de Bocaiúva) foi 37,51±9,45, tais não apresentaram diferença estatística para o intervalo de confiança de 95%, contudo percebe-se uma tendência de aumento na EB com a maior quantidade de bagaço de Bocaiúva, provavelmente por este apresentar maior relação C/N, de 55,80:1 contra 49,48:1 para o T1, confirmando a literatura que afirma que a relação C/N deve ser maior que 29:1. A padronização do cultivo em bagaço de Bocaiúva permitirá uma EB razoável podendo ser utilizado como substrato para futuros cultivos comerciais.

O Método de Ritchie (1948) é uma metodologia eficiente para diagnóstico parasitário em matrizes ambientais, porém apresenta como desvantagem o uso do éter etílico e formaldeído, reagentes toxicológicos para a saúde ambiental e ocupacional. O objetivo do estudo foi padronizar uma técnica adaptada do Método de Ritchie para identificação de parasitas em lodo de esgoto, que evite o uso de substâncias tóxicas e possa ser utilizada em laboratórios de parasitologia. Amostras de lodo foram submetidas ao Método Ritchie (MR) e ao Método de Ritchie Modificado por Régis Anécimo (MRMRA), no qual substancias químicas são substituídas por água a 45°C e detergente neutro. Os resultados demonstraram que, no MR, a porcentagem de Ancylostoma sp foi de 19%, Hymenolepis sp 79%, Ascaris sp 2% e Trichuris trichiura 0%, em um total de 1970 helmintos visualizados. Porém, no MRMRA, a porcentagem de Ancylostoma sp foi de 56%, Hymenolepis sp 40%, Ascaris sp 4% e Tricuris trichiura 0%, em um total de 398 helmintos. Avaliando quantitativamente o MRMRA foi menos eficiente, pois esses resultados demonstraram uma diferença significativa de helmintos visualizados entre os métodos. Porém, enquanto análise qualitativa, a técnica pode ser considerada válida, uma vez que a qualidade da visualização dos parasitas é correspondente em ambos os métodos. Pode ser concluído que o MRMRA é um método simples de realizar e de fácil implementação na rotina de laboratórios e estações de tratamento de esgoto.

El trabajo crítico de Rodríguez Puértolas en relación con la literatura española del siglo XX está fundamentalmente determinado por dos grandes procesos que, en buena medida, caracterizan los conflictos históricos que lo conforman: de una parte, la literatura revolucionaria y los procesos de radicalización, y en algunos casos de proletarización, de los intelectuales españoles (artículos sobre Miguel Hemández, la literatura republicana, Cernuda, etc.), básicamente centrada en la figura de Antonio Machado; de otra, la literatura fascista que dominó un largo periodo de la historia de España. En ambos casos se trata de trabajos de compilación de textos olvidados (los de Machado) u ocultados (los de intelectuales fascistas como Laín Entralgo, Ridruejo, Cela, etc.). Su labor no acata el «consenso social» que habían impuesto las élites franquistas y la oposición en los años de la llamada transición democrática. Los artículos y el libro sobre Machado presentan al poeta y pensador participando activamente en la comprensión de las transformaciones de su tiempo y entregando toda su producción literaria al servicio del pueblo en armas (concretando, con ello, mucho más la idea del Machado «comprometido» y anulando el silencio que se había hecho respecto a sus vinculaciones con las ideologías revolucionaiias fortalecidas con la Revolución de Octubre).

Resumen Los efectos positivos del mindfulness en el tratamiento de múltiples problemas psicológicos en diversas poblaciones han popularizado su uso dentro de la psicología clínica en los últimos años. No obstante, las investigaciones empíricas y revisiones teóricas sobre el mindfulness muestran tres usos diferentes del mindfulness dentro de las aproximaciones conductuales: como proceso, como habilidad y como estrategia. Las discrepancias en las definiciones de mindfulness han generado ambigüedad con respecto a qué y cómo se investiga este fenómeno. En este trabajo se realizó un análisis conceptual de las definiciones del mindfulness de acuerdo con los supuestos filosóficos analíticos-conductuales y contextualistas-funcionales. Finalmente, se discutió la importancia de contar con una definición precisa y unánime con el fin de desarrollar una agenda coordinada de investigación en esse campo.

A caminhabilidade tem sido explorada para avaliar quanto as cidades podem ser atrativas para a mobilidade ativa, no sentido de que cidades caminháveis tornam-se mais seguras, atrativas e permitem uma melhor integração entre diferentes usuários do espaço ao priorizar a escala do pedestre. Neste artigo buscou-se investigar o índice de caminhabilidade no espaço urbano de uma via da cidade de Cajazeiras (PB) utilizando como método a ferramenta iCam 2.0. Como resultados, descobriu-se que o trecho apresenta a condição de insuficiência, principalmente nos quesitos calçadas e segurança pública, determinando os pontos principais de remodelação urbana possíveis para adaptação do espaço com enfoque na ótica do pedestre.

Intracardiac electrophysiological invasive procedures guided by fluoroscopy aim to study the cardiac depolarization process. Depending on the complexity of the clinical case, both patients and professionals are subjected to radiation for a prolonged period. This work evaluated if a direct ions storage (DIS) dosimeter could measure occupational doses in different regions of the physician's body during these procedures. Doses were monitored close to the left eye (LE), right eye (RE), extremity (left ankle), and thorax, as well as the environmental dose, positioning the dosimeter in the center of the equipment gantry. These doses were evaluated in 31 procedures using 01 DIS dosimeter in each region. The Mann-Whitney U test demonstrated that the values obtained in the different regions represent different samples, while the Spearman test demonstrated that there is no evidence that there is a correlation between the data recorded in the different regions. DIS was effective in recording the doses in the LE region and the doses of dispersed radiation (Arc), with the values obtained: (30 quartile / maximum): LE (0.07 / 0.20 mSv); Arc (0.38 / 1.53 mSv). It was not possible to compare occupational doses between different regions of the physician's body, limiting its use as a complementary monitor in the control of occupational doses.

Objective. This review describes the geographic and temporal distribution of, detection methods for, and other epidemiological features of published leptospirosis outbreaks, with the aim of informing efforts to standardize outbreak-reporting practices. Methods. We conducted a systematic review of leptospirosis outbreaks reported in the scientific literature and ProMED during 1970–2012. Predefined criteria were used to identify and classify outbreaks and a standard form was used to extract information. Results. During 1970–2012, we identified 318 outbreaks (average: 7 outbreaks/year; range: 1–19). Most outbreaks were reported in the Latin America and the Caribbean region (36%), followed by Southern Asia (13%), and North America (11%). Most outbreaks were located in tropical and subtropical ecoregions (55%). Quality classification showed that there was clear description of laboratory-confirmed cases in 40% of outbreaks. Among those, the average outbreak size was 82 cases overall (range: 2–2 259) but reached 253 cases in tropical/subtropical ecoregions. Common risk factors included outdoor work activities (25%), exposure to floodwaters (23%), and recreational exposure to water (22%). Epidemiologic investigation was conducted in 80% of outbreaks, mainly as case interviews. Case fatality was 5% overall (range: 0%–60%). Conclusions. Outbreak reporting increased over the study period with outbreaks covering tropical and non-tropical regions. Outbreaks varied by size, setting, and risk factors; however, data reviewed often had limited information regarding diagnosis and epidemiology. Guidelines are recommended to develop standardized procedures for diagnostic and epidemiological investigations during an outbreak and for reporting.

Live cattle export is one of the newest commercial sectors available to Brazilian farmers, but to be exported animals must be free of infectious diseases, especially those prohibited by the countries importing them. In this study, 1,800 bovine sera were collected from animals destined for export in the Brazilian states of Goiás (GO), Minas Gerais (MG), and São Paulo (SP). The sera were tested for bovine brucellosis (BB), paratuberculosis (PTB), enzootic bovine leukosis (EBL), and bovine viral diarrhea (BVD). This was the first study in Brazil to conduct a serological survey for bovine PTB in the states of SP, GO, and MG, and the first survey for BVD in GO. The total percentage of animals positive for each disease was 0.33% (2/1,800) for BB, 16.17% (97/1,800) for PTB, 31.50% (189/1,800) for EBL, and 9.67% (58/1,800) for BVD.

Resumo Nesse estudo buscou-se desenvolver uma metodologia simples, capaz de caracterizar diferentes propriedades de telhas cerâmicas por meio da propagação de ondas acústicas. Para isso, foi utilizada a energia potencial gravitacional provocada pelo impacto de uma esfera de aço em queda livre sobre a superfície de telhas cerâmicas, sendo o sinal acústico capturado com o auxílio de um computador e um software livre. Os resultados obtidos mostraram a viabilidade do método como proposta didática a ser implementada nas aulas de laboratório de materiais de construção, ministradas regularmente nos cursos de Engenharia Civil.

Objetivo: caracterizar la gravedad de los trastornos asociados a sustancias en las personas en tratamiento en los Centros de Atención Psicosocial Alcohol y otras Drogas. Método: estudio transversal, que se realizó en tres Centros de Atención Psicosocial Alcohol y otras Drogas III, en Curitiba-Paraná, con 137 personas con trastornos asociados a sustancias. Se obtuvieron los dados entre abril y noviembre de 2018, por medio de aplicación del instrumento Addiction Severity Index sexta versión, analizándolos de modo descriptivo a partir de frecuencias absolutas y relativas, promedio y desviación estándar. Resultados: del total de la muestra, 89,1% (122) eran del sexo masculino; las sub escalas de mayor gravedad fueron Familia/niños 57,8 (± 8,6), Alcohol 52,8 (±10,9) y Familia/problemas sociales 51,0 (±8,9). Conclusión: El uso de sustancias psicoactivas afecta las relaciones familiares y sociales y el alcohol, una substancia lícita, de fácil acceso, está presente en la vida de las personas desde la infancia, presentando mayor frecuencia entre todas las franjas etarias.

La inclusión de estudiantes sordos en aulas regulares ha puesto en evidencia la necesidad del intérprete de lengua de señas chilena como mediador entre dos lenguas, la lengua de señas y la lengua oral. Por ello, el objetivo de este estudio fue analizar la formación y las funciones del intérprete de lengua de señas chilena en el contexto educativo. El instrumento para alcanzar el objetivo fue una entrevista semiestructurada a doce intérpretes de lengua de señas chilena y a tres actores relevantes de este ámbito. Los resultados muestran la informalidad en el proceso de formación. También evidencian funciones prescritas que se distancian de las no prescritas, y una serie de barreras para el servicio de interpretación establecidas por el contexto educativo, de las cuales surge la figura de facilitador de la lengua de señas chilena. Este contribuye a dar respuesta a las necesidades de acceso a los aprendizajes de los estudiantes sordos en contextos educativos.

During recent decades, and in the context of global movements for educational reforms, a series of inclusive policies have been enacted in Chile. Based on these transformations, the objective of this article is to analyse a set of policies aimed at the attention of special needs students. Methodologically, a documentary work was conducted, in which texts related exclusively to the attention of students with special needs were selected, and which were temporarily published between 1990 and 2018. Thus, a corpus of 14 documents was obtained, seven of which are analysed in-depth in this article. The analysis of the texts occurred in two phases: first, from a hermeneutical distancing process (Ricoeur, 1986, 2003), and, later, from a deconstructive analysis (Derrida, 1997). Among the most relevant findings, the binarisation of inclusion is observed, reducing it to the erection of barriers of accessing and teaching, and the shifting from disciplinary logic associated to normalisation to others of self-regulation. Finally, the emergence of logics of standardised difference was observed, which leans toward a normocentrality, where otherness would be understood as threat.

El artículo problematiza la privatización de los derechos del agua en Chile en perspectiva histórica. Analiza la configuración del papel hegemónico de la Sociedad del Canal Maipo sobre la gestión del agua de riego, como un caso paradigmático que condicionó la estructuración de las redes hidrosociales en Chile, en el contexto del proceso de incorporación del país en los mercados mundiales. Sostenemos que la Asociación de Canalistas del Maipo logró, a partir de una eventualidad histórica particular (aguaceros de 1827 en el Canal San Carlos), apoderarse de un bien común sin ningún contrapeso, ejerciendo un poder despótico sobre el riego que terminó, en el largo plazo, condicionando profundamente la relación entre la sociedad y el agua en Chile. Analizamos diferentes conflictos en torno a las distintas estrategias de control, administración y acceso al agua empleadas por la Asociación, a fin de dilucidar los mecanismos que adoptó con el objetivo de legitimar y perpetuar su predominio y poder.

The multiple positioning of the blended virtual superior education service (EDMIX) or simultaneous positioning, both in the enrolment niche as in the co-producers suppliers, associates in their minds the educative service with the attribute that satisfies each one of them, when more value or priority is perceived in it than in other options of life or occupation, considered in the same category of belonging. For the niche (capable young people, interested, economically vulnerables, no enroled), the perception of the benefits provided by superior education (ES), influenced by the cultural pattern that an profissional academic with a diploma has job, better quality of life and social status, is not enough to position EDMIX, at least that will guarantee: support to attenuate its economic vulnerability, terminal efficacy and vinculation to the productive sector; however, these attributes desired in the educative service need to be positioned in the several co-producers. Under a mixed methodological perspective, a forecaster exploratory design supported in hybrid methods and techniques for the collecting, analysis and interpretation of data, a model of multiple positioning that aligns the interests of each one of the involved towards the strategic objetive of reach a quality service is proposed. The community hopes that the effort invested in a superior preparation will produce, proportionally, human development, at least for the profissional itself; the municipal administration, as facilitator partner of the local instalations and equipment, could enhance and optimize with minimum investment the development of human and social capital; the professors and administrators, could consolidate their professional and vocational expectations; and the students, directly benefited, could obtain what explicitly or implicitly demand: the effectiveness of the project in which they have decided to participate. The sinergy of the quality promoves sustentability; but the disagreement, desertion and/or the positioning no desired of discredit.

O presente artigo tem por objetivo a metodologia da resolução de problemas como uma possibilidade de desenvolver a Educação Ambiental na escola.

This article presents the results of a comparative study on the presence / absence of discursive quality concreteness and metonymic projections on the first and last version of narratives produced by subjects, teachers of Portuguese Language trainees during a course of Specialization / UFGD. We tried to see to what extent the concept of discursive qualities worked with the subjects during the course contributed to the improvement in quality of stylisticdiscursive narratives. From the methodological point of view, the comparative analysis between the textual versions written by the subjects, there was no relationship between the presence of discursive quality concreteness and the presence of metonymic projections (reminiscent, hipalage and synecdoche) in 1st and last version of the narrative. The results indicate the absence of discursive quality concreteness and metonymic projections in version 1st and effective presence in the latest version of the texts resulting in a positive discourse-stylistic effect when comparing the 1st and the last version rewritten by the subjects.

This paper explores some of the advances in the institutionalization of political science in Colombia, considering that the stages of its creation as a vocation (1968-1990) and its expansion as a profession (1990-2006) have been completed. To do this, the article presents a brief overview of the history of political science in the country, with emphasis on the second half of the twentieth century. It also shows that advances in the institutionalization process of the discipline are linked to the creation of the Colombian Association of Political Science (ACCPOL) and the establishment of shared content and criteria in political science programs within the country.

Partiendo del paralelo que se establece tempranamente entre cine y sueño, y mostrando el cambio que se produce en las teorías cinematográficas de lo que suele llamarse la metapsicología del espectador al estudio histórico del dispositivo cinematográfico, este artículo estudiará la aparición del “oniroscopio” (una máquina fantástica con la que se puede observar los sueños) en el cine. Después de algunas observaciones generales, se pasará a analizar más en detalle las películas argentinas No te mueras sin decirme adónde vas (Eliseo Subiela, 1995) y La sonámbula (Fernando Spiner, 1998) con el fin de interrogar las modalidades de representación que presupone el oniroscopio como forma de metadispositivo crítico.
