Authors: Linares-Gabriel Ariadna , Rodríguez-Orozco Nereida , Hernández-Chontal Mario Alejandro
Published: April 2019

Ensuring extension of the vase life of Heliconia commercial stems is essential for the consumer acceptance process. For this, the objective of this research was to evaluate the effect of hydration on the vase life of two Heliconia cultivars. The experimental design was in randomized blocks with subdivided plots (cultivar x hydration) with 6 replicates, being cultivars x hydration: no hydration (control), water hydration and hydration + sugar. The results considering cultivars as a factor showed a statistically significant difference (P ≤ 0.05). According to the comparison of means (P ≤ 0.05), the Heliconia psittacorum x spathorcinata tropics showed the best response. Both hydration and interaction between cultivars, showed no significant differences (P ≤ 0.05). Hydration did not guarantee a greater number of days of durability, so it is a good alternative, the use of dry treatment and the reduction on the excessive water use, according to the results obtained in this study.
The encyclical Laudato si’ in the context of modernity: a voice in the dialogue on the ecological crisis
Authors: Florensa IQS Albert , Menacho IQS Joaquin
Published: April 2019

El hecho de que vivamos en un mundo plural e interconectado hace necesario que los problemas comunes, como la crisis ambiental, se resuelvan en común. Una de las mejores maneras de lograr esto es a través del diálogo, cuanto más extenso, mejor. La pluralidad, que tiene muchas virtudes, también puede llevar a dificultades al definir las condiciones de posibilidad de dicho diálogo. El presente trabajo desea analizar si la Iglesia Católica, a través de la encíclica «Laudato Si» del Papa Francisco, podría ser un interlocutor válido en la crisis ambiental, específicamente en el contexto de la modernidad. ¿Puede un texto escrito por la máxima autoridad del catolicismo ser de interés para otros, aparte de los creyentes de esta religión y los eruditos que estudian los fenómenos religiosos? ¿Las críticas de LS a la tecnociencia implican un rechazo de la modernidad, dado que la tecnociencia es una parte inequívoca de la racionalidad moderna?
Assessment of eco-diversity status of Homalomena aromatica (Spreng.) Schott and its habitat in tropical forest of Indian Eastern Himalaya
Authors: Ronald Khumukcham , Gajurel Padma Raj , Singh Binay
Published: April 2019

Homalomena aromatica (Spreng.) Schott is one of the economically important plant species occurring in the North east and Eastern Himalayan region of India which received least attention in its ecological and conservation studies. The current study has been undertaken in the north eastern state of Arunachal Pradesh. The population, phytosociological status of its habitat, regeneration and species association of H. aromatica were worked out using standard ecological methods. Out of the 15 selected forest sites for survey, H. aromatica was found only in 9 sites. A total of 288 species representing 99 families are documented from the selected sites where Euphorbiaceae, Meliaceae, Araceae, Dipterocarpaceae and Poaceae are found dominant in all the 9 sites. Species diversity index (H?) of all the three habits i.e. the tree, shrub, and herb were found highest in Happy Valley site followed by Ganga Lake. A total of 219 individuals of H. aromatica recorded which were found confined within the altitudinal ranges of 350m-450m asl. The IVI (1.95 to 9.64) and Frequency % (5 to 12.5) range of H. aromatica found significantly low at all the survey sites. Pearson’s correlation analysis reveals that there is a positive relationship between the population size and the species diversity index, where shrub showed the strongest relationship (r(7)=0.900, P=0.001) followed by tree r(7)=0.736, P=0.024 and the herbs with weakest relationship (r(7)=0.39, P=0.269). The Chi-square test of association indicated significant association of 10 species with H. aromatica in the various sites where Alocasia acuminate (Aracaceae), Amomum sp. (Zingiberaceae) and Pteris sp. (Pteridaceae) showed highest association with higher Chi square value. The poor population status with average density of 3041.67/hectare and 8.89 frequency percentage as well the existing anthropogenic threats to the species recorded in the present study has warrants for its immediate conservation.
Individual entrenchment vs. community-wide conventionalization of contact features in L2 Basque speakers’ individual styles
Authors: Lantto Hanna
Published: April 2019

This article examines individual variation of contact features in the speech patterns of four L2 Basque speakers. The individual styles are examined through the concepts of individual entrenchment and community-wide conventionalization to bridge the gap between linguistic variation and change at the individual and social levels. All the informants speak Spanish as their L1. They have acquired Basque in classroom contexts, and they belong to the same macrosociolinguistic categories. Yet their patterns of using the language contact between standard Basque, vernacular Basque dialects and Spanish as a resource in creating individual speech styles differ considerably, reflecting their language attitudes and their personal experience. Nevertheless, there are conventionalized patterns that emerge out of this diversity: All speakers use the standard Basque as the base language, and none of them adopts of vernacular variety as a whole. The Spanish resources seem to be used mainly for pragmatic and stylistic functions, whereas the features of vernacular Basque that the speakers have adopted as part of their individual styles are high frequency elements of core grammar.
Vitamin D status and its relationship with systemic lupus erythematosus as a determinant and outcome of disease activity
Authors: Dutta Chayanika , Kakati Sanjeeb , Barman Bhupen , Bora Kaustubh
Published: April 2019

Background

The importance of vitamin D (VD) in systemic lupus erythematosus (SLE) is being increasingly appreciated, with studies suggesting a relationship between VD deficiency and SLE onset/disease activity. We investigated VD status in SLE patients and its associations with disease activity in a geographical region of India receiving low solar ultraviolet-B (UV-B) index.

Materials and methods

We enrolled 109 SLE patients along with 109 healthy controls belonging to same ethnicity and localities. Demographic and clinico-laboratory information were recorded. VD status was assessed by estimating serum 25-hydroxyvitamin D (25-OH-D) concentrations (deficient: <20 ng/mL, insufficient: 21–29 ng/mL, and sufficient/normal: ≥30 ng/mL) using an enzyme-linked fluorescent assay (ELFA). The SLE Disease Activity Index (SLEDAI) scoring system was used to evaluate disease activity. The association between VD status and disease activity was assessed by univariate and multivariate approaches.

Results

Hypovitaminosis D was prevalent in 90.83% SLE patients [vs. 77.98% healthy controls; chi-squared (χ2) = 10.125, df = 2, p < 0.01]. SLEDAI scores and 25-OH-D values were inversely associated, which extended in a two-way manner as revealed by multiple logistic regression models. SLE patients with VD deficiency were more likely to have high/very high disease activity [adjusted odds ratio (OR) = 3.5, 95% confidence intervals (CI): 1.4–8.9]. Conversely, patients with high SLEDAI scores (>10) also had greater risks of being VD deficient (adjusted OR = 3.9, 95% CI: 1.5–10.8).

Conclusion

VD deficiency is widespread in SLE. The relationship appears to be bidirectional, with VD status associated both as determinant and outcome of disease activity in SLE.
The Youden Index in the Generalized Receiver Operating Characteristic Curve Context
Authors: Martínez-Camblor Pablo , Pardo-Fernández Juan Carlos
Published: April 2019

The receiver operating characteristic (ROC) curve and their associated summary indices, such as the Youden index, are statistical tools commonly used to analyze the discrimination ability of a (bio)marker to distinguish between two populations. This paper presents the concept of Youden index in the context of the generalized ROC (gROC) curve for non-monotone relationships. The interval estimation of the Youden index and the associated cutoff points in a parametric (binormal) and a non-parametric setting is considered. Monte Carlo simulations and a real-world application illustrate the proposed methodology.

Authors: Mann Navjot S. , Makkar Sameer , Sharma Reetika
Published: April 2019

Introduction The aim of this study was to evaluate marginal sealing ability of newly introduced Dyad Flow flowable composite and compare to total-etch and self-etch adhesive system at the coronal and apical margins of class V resin composite restorations.

Material and Methods A standard class V cavity (3 mm mesiodistal width, 3 mm occlusogingival height and 1.5 mm axial depth) was prepared on the buccal surface of freshly extracted sound human teeth. Occlusal and gingival margins of the cavities were located in enamel and cementum/dentin, respectively. Teeth were randomly assigned into the three groups (n=10) and restored with different composite materials following the manufacturer’s instructions: group I was restored with nanohybrid resin composite using total-etch bonding agent; group II was restored with nanohybrid resin composite using self-etch technique; group III was restored with flowable composite (Dyad Flow), respectively. After finishing and polishing, the teeth were coated with nail varnish and immersed in rhodamine B dye and sectioned longitudinally. Dye penetration was examined under stereomicroscope and scored separately for occlusal and gingival margins on a 0–3 ordinal scale. Data were analyzed with Kruskal–Wallis, Mann–Whitney and Wilcoxon tests (a=0.05).

Result Statistical analysis showed that specimens restored with the total-etch and self-etch adhesive systems revealed reduced leakage at the coronal margin. At the apical margin, Dyad Flow showed greater leakage than other groups.

Conclusion Newly introduced flowable composite Dyad Flow showed inferior adhesive bond with enamel and dentin compared to total-etch and self-etch techniques.

Introduction There is growing interest in the world for estimating the cost for the treatment of a disease. This value can be used to determine to which extent a particular disease or group of diseases burden society in terms of the global crisis (Segel 2006). In 2000, Organization for Economic Countries Development (OECD) established a System of Health Accounts (SHA), and provided methodological guide for calculating the cost of treating the disease.

The aim of this study was to determine the cost of individual health care in the Republic of Serbia according to the major International Classification of Diseases (ICD) for the period 2010-2015.

Material and Methods A retrospective and comparative analysis of health statistics from the database of the Institute of Public Health of Serbia (IPHS) and financial information provided by the National Health Insurance Fund (NHIF) in the period 2010-2015 was performed. Financial information and data on hospital services, outpatient, home health care, auxiliary health care services, drug consumption and consumer goods in healthcare were analyzed using SHA methodology.

Results showed that during observation period the maximum cost of individual health care in Serbia by main classification ICD was achieved in 2015 and it was 194,128,864,011 RSD (€1,580,853,941; $1,764,807,854) and the minimal cost was achieved in 2010, 151,333,139,835 RSD (€1,434,464,541; $1,908,843,843).

Conclusion The cost of individual health care in the Republic of Serbia in the period 2010-2015 increased by thirty percent. The highest amount was allocated to treat people with diseases of the circulatory system.

Published: April 2019

Introduction The aim of this study was to evaluate the efficacy of new rotary NiTi instrument XP endo SHAPER (XPS) used with conventional irrigation protocol on the root canal cleaning in the apical area.

Material and methods The research was conducted in vitro on 40 extracted single-rooted teeth divided into the four groups. Instrumentation in the first group was performed using iRa Ce NiTi rotary instruments, in the second group the same instruments were used plus XP endo FINISHER (XPF) for smear layer removal. In the third group, canal instrumentation was done using new instrument XPS, and in the fourth XPS instruments plus XPF was used. During the instrumentation 2% NaOCl solution was used for rinsing canals. The SEM analysis of the cleaning quality in the apical third of the canal was performed on longitudinal root cross-sections and standardized microphotography with a 2000x magnification.

Results The thickest smear layer in the apical third was recorded in the first group (iRa Ce) NiTi instruments (2.12), and somewhat less in the group with the new XPS instrument (1.95). An identical and somewhat smaller amount of smear layer was registered in the second and fourth groups where XPF was used with the final irrigant (1.64) (p<0.001).

Conclusion The application of only one instrument (XPS) in the canal enabled efficient cleaning of a very complex apical third. Cleaning was more efficient when XPF was used with final irrigant after the canal instrumentation.
Analytical Models for 3-D Diffusion of Ions from Salt-Contaminated Aggregates
Authors: Thomas Robert J. , Sorensen Andrew D. , Maguire Marc
Published: April 2019

This article presents an analytical investigation of the mobility of salts from contaminated aggregates in concrete. Salt-contaminated aggregates may have varied effects on the mechanical properties and durability of concrete. These depend primarily on the mobility of salts within the concrete matrix. Existing diffusion-based models for the mobility of salts in concrete focus on their intrusion from external sources (e.g., chloride penetration from deicing salts and brines). Such problems are well described by the closed-form solution of Fick’s law for diffusion in one dimension from a continuous source. Salt-contaminated aggregates represent a case of diffusion from a finite internal source rather than intrusion from a continuous external source. When the source is internal—as in the case of salt-contaminated aggregates—diffusion occurs in three dimensions and the source is finite. The 1-D solution is ill conditioned to model this problem, so new diffusion models must be introduced. This article presents two models of varying complexity that are well conditioned to model diffusion of salts from contaminated aggregates. First, the problem is modeled using Fick’s law for the simplified case of 3-D diffusion from an instantaneous point source in an infinite medium. Contaminated aggregates are treated as infinitesimal slugs of diffusing material. The same problem is then modeled using Fick’s law for the more realistic case of 3-D diffusion from an instantaneous spherical source, where contaminated aggregates are treated as approximately spherical. The intent of this article is to present an academic discussion on how chloride ions might migrate within the concrete matrix if they are assumed to do so by diffusion alone.
Microstructural Characterization of Portland Cement Concrete Containing Reclaimed Asphalt Pavement Aggregates Using Conventional and Advanced Petrographic Techniques
Authors: Mukhopadhyay Anol , Shi Xijun
Published: April 2019

Potential issues associated with depletion of good aggregate sources and management of excess reclaimed asphalt pavement (RAP) stockpiles increasingly motivate the use of RAP in portland cement concrete (PCC) as an aggregate replacement. Although the mechanical properties of the PCC containing RAP (RAP-PCC) have been extensively studied, detailed microstructural characterization and understanding crack propagation in RAP-PCC is yet to be established. Although thin-section-based petrographic study (ASTM C856, Standard Practice for Petrographic Examination of Hardened Concrete) combined with scanning electron microscope-energy dispersive x-ray spectroscopy (SEM-EDS) provides useful information on this aspect, both methods introduce artifacts associated with destructive sample preparation techniques. High-resolution X-ray computed tomography (X-ray CT) testing has the merits to provide three-dimensional (3D) dispositions of the microstructural features nondestructively and can be used effectively to validate the observation based on conventional techniques. This paper presents a comprehensive microstructural characterization and crack propagation of RAP-PCC through a combined approach of thin section based petrographic observation, SEM-EDS, and X-ray CT. Thin-section study was useful to (1) identify agglomerated RAP particles, (2) characterize air void distribution and quantify air voids content, and (3) perform overall characterization of interfacial transition zone (ITZ). The SEM-EDS was used for a detailed characterization of ITZ and calcium hydroxide distribution. Based on thin-section and SEM studies, a cohesive failure through the asphalt layer was identified as the primary mechanism for strength reductions in RAP-PCC. X-ray CT was used to scan the RAP-PCC samples with high resolution followed by image reconstruction to generate 3D images of the specimens, which was effective not only to validate the cohesive failure mechanism but also to provide an extensive analysis of multiple features, including air void distribution and quantification and crack propagation.
Implementation of Mineralogical Analysis in Cement Processing
Authors: van Weeren Harald , van der Haar Marco , Kemmerer Jeffrey
Published: April 2019

Assessment of the mineralogical phase composition of cement and its intermediates play an increasingly important role in cement production. Traditionally, sampling for phase analysis has mostly focused on the kiln and cement. The most essential mineralogical analysis is the free lime quantification for optimizing kiln operation along with the quantification of alite, belite, aluminate, and ferrite to judge the clinker quality. With the drive for more efficient and environmentally friendly cement production, the application of phase analysis has further extended to the analysis of blended cements containing supplementary cementitious materials, such as fly ash, slag, silica fume, or pozzolan. Moreover, mineralogical phase analysis can offer an attractive means for further process optimization in various stages of the cement production process. In this paper, we provide an overview and practical examples of how accurate phase analysis using X-ray diffraction at the various stages in the process helps to produce cement more efficiently and in a more environmentally friendly manner. Furthermore, we discuss the latest X-ray techniques for accurate and rapid mineralogical phase quantification for efficient process control.
Machismo y violencia contra la mujer
Authors: Oblitas Béjar Beatriz
Published: April 2019

El estudio permite inferir que hay un doble discurso, el de la realidad y el del deseo. El de la realidad hace reconocimiento de lo que es ser hombre y ser mujer en el sistema patriarcal a partir de las pautas machistas que la sociedad asigna. Las mujeres se siguen ubicando en el terreno de lo privado/doméstico,  responsables de brindar cariño y cuidado a los hijos. El discurso del deseo que pasa como real, lo que señala es lo ideal respecto a la relación hombremujer. Cuando las respuestas de este discurso se comparan con las otras, es cuando aparecen como una aspiración, es el caso de las opiniones referidas al trabajo de hombres en jardines de infancia, al llanto de los hombres, a la infidelidad, a la violencia entre pareja o cuando los hombres no se consideran machistas. La violencia contra la mujer está asociada estrechamente al sistema patriarcal o sistema machista, como se le llama coloquialmente. Este sistema justifica, reproduce y tolera una serie de imaginarios y prácticas entre hombres y mujeres, que partiendo de la desigualdad y discriminación de géneros, termina afectando la vida familiar.

Authors: Cristina Florez Gloria
Published: April 2019

La génesis del Estado Moderno en Occidente iniciada a fines del siglo XIII y que ha logrado su consolidación en el siglo XVIII necesitó realizar ciertas modificaciones y emplear diversos recursos para legitimar el poder monárquico. Entre ellos destaca la dinámica intelectual, que comprende aspectos muy variados tales como: las imágenes, los discursos y los tratados políticos pero también los espectáculos, las ceremonias cívicas y religiosas. Hemos elegido entre esos recursos, algunos ejemplos de la prédica en el Perú del siglo XVII y mostrar así el papel importante que tuvieron los sermones legitimando la monarquía de los Austrias en nuestro territorio
Hacia una metodología de análisis etnológico del arte y representaciones andinas prehispánicas
Authors: Arana Bustamante Luis
Published: April 2019

RESUMEN Hago aquí una revisión de las orientaciones teóricas principales empleadas en el estudio e interpretación del arte prehispánico andino, aunque desde esta perspectiva el asunto se entrecruza completamente con aspectos como el planeamiento arquitectónico o el diseño monumental, lo cual trataremos en otra comunicación. Como parte preliminar de la aplicación de un enfoque más etnológico al tema, y en la medida en que se partirá de que todas estas representaciones prehispánicas reflejan y están concebidas a partir de las concepciones cosmológicas de los pueblos e individuos que las llevaron a cabo, examino aquí los enfoques anteriores que han empleado una orientación etnológica y expongo algunos aspectos de la aplicación que propongo de una concepción amplia que he planteado sobre la naturaleza de la cultura (2011) a este amplio asunto. Exploro ya en los principios teóricos mismos de este enfoque propuesto sobre el tema que se derivan de esta concepción, pero no trato ahora estos principios cosmológicos amplios —por otro lado más o menos conocidos en otras sociedades sudamericanas— pero no muy aplicados al caso andino. Mostraré de modo preliminar cómo tanto el uso combinado de algunos aspectos de las diversas ópticas adoptadas sobre el fenómeno simbólico, así como el carácter ‘estratigráfico’ de la cultura en la concepción propuesta —incorporando el factor diacrónico y de la transformación histórica— permitirían desarrollar los fundamentos de una metodología que permita comparaciones y diferenciaciones más controladas en el análisis e interpretación de significados en esta producción artística y las otras representaciones mencionadas.

La lenta estructuración de la iglesia a través de la instrucción de 1545 y los concilios limenses, siglo XVI
Authors: León Fernández Dino
Published: April 2019

Los dos primeros Concilios Limenses establecieron, pues, los fundamentos de la iglesia en los Andes y determinaron las grandes orientaciones a seguir por todos cuantos profesan la fe católica. Los prelados y autoridades proclaman las normas por ser observados los indígenas que recibieran el bautismo, y se preocuparon por aquellos que aún no eran bautizados. Este intento de adaptación está re ejado en las normas dadas por el citado Concilio en la parte concerniente a la evangelización de los naturales. Y la principal labor del Tercer Concilio es la importancia dada al Catecismo, Confesionario y Sermonario.

Published: April 2019

Las luchas fraticidas desatadas en el Tahuantinsuyo y la conmoción sufrida por sus gentes, ante la llegada de hombres y animales desconocidos, precipitaron el derrumbe de aquel Estado aparentemente sin resistencia. Pero una vez superada la sorpresa, los incas pusieron cerco al Cusco y, tras no poder tomar la ciudad, se refugiaron en las montañas de Vilcabamba, desde donde, tratando de expulsar a los extranjeros, iniciaron una incómoda guerra de guerrillas, durante casi cuarenta años, que sucesivamente dirigieron cuatro príncipes cusqueños descendientes del poderoso Huayna Cápac. En este artículo, mediante el estudio de nueva documentación, se aborda la figura y la muerte de Topa Amaro, el último gobernante vilcabambino; se analiza la evolución arquitectónica del Qorikancha, el templo en que recibieron sepultura los restos mortales del Inca, y se exponen los trabajos realizados para encontrar su cripta mortuoria

Abstract Background Elevated arterial stiffness is associated with increased cardiovascular mortality. The relationship between arterial stiffness and critical limb ischemia (CLI) is not well established. Objectives The objective of this study is to analyze the relationship between arterial stiffness indices and the degree of limb ischemia measured by the ankle-brachial index (ABI). Methods A cross-sectional study comparing patients with CLI and controls. Arterial stiffness was measured using brachial artery oscillometry. The arterial stiffness indices pulse wave velocity (PWV) and augmentation index normalized to 75 beats/min (AIx@75) were determined. Multiple linear regression was applied to identify predictors of arterial stiffness indices. Results Patients in the CLI group had higher PWV (12.1±1.9 m/s vs. 10.1±1.9 m/s, p < 0.01) and AIx@75 (31.8±7.8% vs. 17.5±10.8%, p < 0.01) than controls. Central systolic pressure was higher in the CLI group (129.2±18.4 mmHg vs. 115.2±13.1 mmHg, p < 0.01). There was an inverse relationship between AIx@75 and ABI (Pearson coefficient = 0.24, p = 0.048), but there was no relationship between ABI and PWV (Pearson coefficient = 0.19, p = 0.12). In multiple regression analysis, reduced ABI was a predictor of elevated levels of AIx@75 (β = -25.02, p < 0.01). Conclusions Patients with CLI have high arterial stiffness measured by brachial artery oscillometry. The degree of limb ischemia, as measured by the ABI, is a predictor of increased AIx@75. The increased AIx@75 observed in CLI may have implications for the prognosis of this group of patients with advanced atherosclerosis.

Resumo Fístulas arteriovenosas (FAVs) renais adquiridas são raras, correspondendo a uma conexão anômala entre o sistema arterial e o sistema venoso. As FAVs renais se dividem em três grandes grupos: idiopáticas, congênitas e adquiridas, sendo as últimas as mais comuns. Atualmente, têm incidência aumentada em decorrência do crescente número de biópsias renais. Apesar de, atualmente, o procedimento de biópsia renal ser relativamente seguro, ele carrega como complicação a formação de FAV no território vascular renal. O tratamento de FAV renal é amplamente discutido na literatura e diversas modalidades terapêuticas podem ser aplicadas. Apresentamos um caso de FAV pós-biópsia renal que foi submetida a tratamento endovascular com sucesso mediante embolização com molas.

ABSTRACT: Albinism is a genetic disease characterized by deficient melanin production making affected animals more susceptible to skin problems, negatively influencing production systems of the same. In buffalo, a nonsense mutation (c.1431G>A) in the tyrosinase gene was already described, which is responsible for the oculocutaneous albinism buffalo phenotype. However, prevalence studies have never been performed for this anomaly in Brazil. Therefore, the objective of this study was to investigate this mutation in buffalo herd in Brazil. Of the 315 buffalo tested with no albinism phenotype evident, 11 (3.5%) were heterozygous for the mutation and none were mutated homozygous, showing the existence of the albinism gene in buffalo production herds and proving the importance of prevalence studies for hereditary diseases in order to prevent the dissemination of these same genes and their negative productivity consequences.
IGUALDADE SUBVERSIVA CONTRA O CINISMO DEMOCRÁTICO LIBERAL
Authors: Mendonça Daniel de
Published: April 2019

Resumo O objetivo do artigo é discutir teoricamente a relação entre democracia liberal e desigualdade, na defesa da ideia de que a luta pela igualdade é sempre um profundo e necessário ato de subversão política contra uma estrutura de poder estabelecida. Para a consecução desse objetivo, inicialmente, apresentamos a discussão acerca do fundamento democrático da vontade dos iguais. Na sequência, articulamos a relação entre um sistema político e a necessária exclusão que ele promove. Na seção seguinte, analisamos a ideia da lei como a arbitrariedade. Por fim, propomos, tendo em vista o fundamento democrático da vontade dos iguais, que a lei seja preterida em nome desta vontade, que o sistema jurídico seja um meio de execução da decisão política e não o contrário, como comumente tem ocorrido nas democracias ocidentais.
MAPEANDO AS CONTROVÉRSIAS QUE ENVOLVEM O PROCESSO DE MEDICALIZAÇÃO DA INFÂNCIA
Authors: Barbosa Saionara Aparecida
Published: April 2019

Resumo O presente artigo tem como finalidade apresentar aspectos da discussão sobre as controvérsias presentes no processo de medicalização infantil, fruto de um estudo ainda em andamento, em um Programa de Mestrado em Psicologia1, orientado pela teoria Ator-Rede. Podemos observar que, no âmbito infantil, a medicalização provocou mudanças significativas, que se estendem desde o crescente aumento de seu uso até às constantes mudanças na visão de um trabalho viável com os pequenos. O brincar, visto como uma atividade não só de lazer, mas de elaboração e resolução de conflitos, está sendo, em muitos casos, relegado a um segundo plano e substituído pela medicação. Para mapear as controvérsias e entender como a rede da medicalização infantil tem sido construída, é necessário ouvir os atores envolvidos e seguir as cadeias que dão emergência a esse fenômeno.
COTIDIANO DE UMA EXPERIÊNCIA URBANA INFORME: DILACERAMENTOS, TRAJETÓRIAS E POLÍTICAS DO COMUM
Authors: Batista Lazaro
Published: April 2019

Resumo O texto busca estabelecer articulações entre o cotidiano como categoria conceitual e as formas de experimentação urbana dele decorrentes. Para tanto, recorremos a Michel de Certeau, Michel Blanchot e outros autores a fim de estabelecer um contraponto e oposição entre uma noção de cotidiano como existência rotineira, sossegada e acabada e outras formas de apreensão conceitual que apostam na potência de inventá-lo e efetivá-lo em processos diversos, paradoxais e informes. Como indicativo dessa dupla visada, recorre-se a uma imagem do dia a dia urbano de uma cidade brasileira. Com os afetos por e com ela evocados, sugere-se positivar a experiência urbana a partir dos paradoxos de um cotidiano informe e ordinariamente comum, efetivada nos dilaceramentos, tremores e vertigens dos modos instituídos de uso, consumo e apropriação da vida, da cidade e de suas histórias.

ABSTRACT Due to water limitations in terms of both quantity and quality in the semi-arid region of northeastern Brazil, the use of waters with high concentrations of salts become necessary in irrigated agriculture. Thus, this study aimed to evaluate the growth and production of grafted West Indian cherry under saline water irrigation and potassium fertilization. The experiment was carried out in drainage lysimeters under protected environment conditions, using a Regolithic Neosol with sandy loam texture. Treatments resulted from the combination of two levels of electrical conductivity - ECw (0.8 and 3.8 dS m-1) of irrigation water and four doses of potassium (50, 75, 100 and 125% of the recommendation of Musser), arranged in a randomized block design, with three replicates. Irrigation water salinity of 3.8 dS m-1 markedly inhibited the growth in stem diameter and mean fruit weight of West Indian cherry. Potassium fertilization mitigated the deleterious effects of salt stress on the relative growth in stem diameter of the rootstock, total number of fruits and total fresh mass of fruits of West Indian cherry, with highest values in plants irrigated with water of lowest level of salinity associated with the highest dose of K2O.
A maternidade como resistência à violência de Estado
Authors: Santiago Vinicius
Published: April 2019

Resumo Este trabalho analisa o movimento de mães que perderam seus filhos, assassinados por policiais militares nas favelas do Rio de Janeiro, como um dos efeitos perversos da política de pacificação das favelas. A luta das mães pela responsabilização e pelo reconhecimento do Estado brasileiro pelas mortes de seus filhos as inscreve em um movimento que mobiliza a maternidade como símbolo central para o engajamento político. É sobre os limites e ambivalências da maternidade que as mães mobilizam as condições para catalisar um espaço de aliança e resistência. A violência perpetrada sobre os filhos também atinge essas mulheres, cujos corpos maternos se tornam protagonistas no enfrentamento à violência de Estado.
Dançarinas no "circuito integrado" televisivo: problemas de gênero e sexualidade na busca pela audiência*
Authors: Bispo Raphael
Published: April 2019

Resumo O objetivo deste artigo é contribuir para uma história do audiovisual no Brasil a partir da experiência das chacretes, dançarinas que acompanhavam Chacrinha, nos anos 1970, no programa de televisão que apresentava. Busca-se refletir sobre as questões de gênero e sexualidade recorrentes nas estratégias de mercado adotadas pelos produtores de TV. A fim de matizar tais narrativas técnico-científicas de busca pela audiência, a proposta é realçar também as conexões afetivas tecidas pelas chacretes com seus telespectadores, particularmente com as "mulheres donas de casa", "público-alvo" dos programas de auditório.
Museus, mulheres e gênero: olhares sobre o passado para possibilidades do presente*
Authors: Brulon Bruno
Published: April 2019

Resumo Na Museologia, campo predominantemente constituído por mulheres no Brasil, o papel dessas profissionais se mostrou, ao longo da história da disciplina, submetido à tutela masculina, reproduzida e naturalizada nos museus. Por meio da análise histórica, este artigo busca evidenciar a subversão da dominação masculina no campo acadêmico da Museologia, por meio da mudança do papel desempenhado por museólogas brasileiras no século XX. As reflexões sobre o passado nos levam a considerar as relações de gênero na Museologia, evidenciando relações de poder construídas historicamente nesse campo, ou, ainda, nos levam a pensar uma museologia pelo viés queer, subvertendo por completo as categorias identitárias reproduzidas nos museus.

Published: April 2019

Resumo Descreve-se as noções de "terapia" hormonal em cenários medicalizantes nos quais homens transexuais se movem na constituição de transições de gênero. Em meio aos acessos e práticas à (auto)administração de ésteres de testosterona (cipionato e/ou propionato), esses sujeitos acionam a ideia de "terapia" - seja para se afastar ou para reiterá-la -, levando-nos a uma reflexão sobre a atual classificação da transexualidade como doença mental. Realizou-se pesquisa etnográfica em grupos de ativismo trans no Brasil com entrevistas em profundidade no período de 2014 a 2015.

Abstract Introduction: The gastroplasty post-operative period can alter respiratory mechanics and predispose patients to respiratory complications. Objective: The objective was to evaluate the effects of exercises with inspiratory load on respiratory muscle function and on the prevalence of atelectasis after gastroplasty. Method: 40 participants were randomly allocated into two groups: Control Group (CG), its members underwent conventional respiratory physical therapy (CRP) and the Inspiratory Load Group (ILG), its members performed exercises with linear inspiratory pressure load, with 40% of the maximum inspiratory pressure (MIP), associated with CRP. Therapy procedures were conducted twice during the immediate post-operative period and thrice on the first post-operative day. In addition to evaluating the MIP, the nasal inspiratory pressure (NIP) and the sustained maximum inspiratory pressure (SMIP) were evaluated before and after treatment. Analysis of variance followed by the Bonferroni correction were applied considering a 5% significance level (p < 0.05). Results: There was no significant difference in NIP and SMIP values when the pre- and post-operative periods were compared for the ILG; however, these values were significantly lower for the CG, also with intergroup differences in NIP values. Atelectasis prevalence was 5% for ILG and 15% for CG, with no intergroup difference. Conclusion: The inspiratory muscle strength and resistance of the respiratory muscles were maintained in the group that performed exercises with inspiratory load associated with CRP, with a low rate of atelectasis after gastroplasty.
