Testemunhos de Sobreviventes ao Desastre de 2011 em Petrópolis: Abordagem Psicossocial em um Campo Ferido
Authors: Younes-Ibrahim Samira , Pinheiro Marta De Araújo , Pardo Catalina Revollo
Published: August 2019

Este artigo apresenta uma análise dos testemunhos de sobreviventes ao desastre ocorrido em 2011, no Vale do Cuiabá (Petrópolis, RJ), região serrana do Estado do Rio de Janeiro, a partir de uma abordagem psicossocial. Os testemunhos foram coletados sete anos após a tragédia por meio de entrevistas individuais e grupais e mostram que o desastre continua. Dentre os resultados, evidencia-se que as pessoas entrevistadas se percebem como sobreviventes e não como afetados, atingidos ou vítimas; a vivência do abandono permanece com a ausência do Estado; e a precariedade das políticas públicas praticadas fragmentaram as relações comunitárias, gerando comprometimento da comunicação interpessoal. Destaca-se que o desastre permanece enquanto durar o sofrimento social dos envolvidos e que os profissionais que atuam nesse campo necessitam desenvolver uma escuta qualificada.

Published: August 2019

O objetivo do presente estudo foi analisar as representações sociais dos surdos universitários acerca da sexualidade. Esta pesquisa teve como aporte teórico a Teoria das Representações Sociais (TRS), que possibilita compreender a sexualidade, além do aspecto individual, elucidando a função do saber compartilhado. Tratou-se de uma pesquisa descritiva, com abordagem qualitativa, realizada com cinco universitários surdos que foram entrevistados de forma individual, em Língua Brasileira de Sinais (Libras) e por meio de um roteiro semiestruturado. Utilizou-se o Software IRAMUTEQ para a análise dos dados mediante a Classificação Hierárquica Descendente (CHD). Observou-se que as representações sociais da sexualidade dos participantes estão ancoradas no cuidado com a saúde sexual, no futuro profissional e nas relações amorosas, nas relações com a comunidade surda e com os familiares. Com isso, foi identificado que os participantes tiveram preocupação com a afetividade, o bem-estar, a atividade sexual e a satisfação em seus relacionamentos. No entanto, percebe-se a necessidade de desmistificar a temática entre os jovens surdos para que esses desenvolvam a sexualidade com autonomia.
Concepções de famílias: Um estudo sobre as representações gráficas de crianças cariocas
Authors: Landim Ilana , Borsa Juliane Callegaro
Published: August 2019

As configurações familiares estão em processo de diversificação, de maneira que o modelo formado por homem e mulher unidos em matrimônio não é o único a ser legitimado pela sociedade. Este estudo objetivou investigar de que forma as crianças cariocas representam graficamente as famílias, tomando como base a teoria da análise do comportamento. Participaram da amostra 108 crianças cariocas (52,8% meninos e 47,2% meninas), com idades entre cinco e 12 anos (M= 8,58; DP= 1,54) e seus respectivos responsáveis (M= 36,9; DP= 7,31). Foi solicitado que as crianças desenhassem individualmente uma família e a descrevessem. Aos responsáveis foi pedido que preenchessem um questionário sociodemográfico. Os conteúdos dos desenhos e os dados do questionário sociodemográfico foram tabulados e analisados por meio do software estatístico IBM SPSS versão 22. A maior parte das crianças representou famílias tradicionais em seus desenhos. No entanto, as concepções de família pareceram mais associadas à dimensão afetiva que aos espaços de convivência e moradia. Esse estudo propôs novas perspectivas empíricas e teóricas para avaliar o desenho da família e sugere a necessidade de melhor compreender como os diversos arranjos familiares são apreendidos pelas crianças.
Estilos de uso e significados dos autorretratos no Instagram: Identidades narrativas de adultos jovens brasileiros
Authors: Hage Zakiee Castro Mufarrej , Kublikowski Ida
Published: August 2019

O Brasil é o segundo país que mais acessa o Instagram e seu público mais conectado são os adultos jovens. Com foco na constituição de identidades narrativas e de uma perspectiva sistêmica, a presente pesquisa buscou identificar quantitativamente os estilos de uso e compreender qualitativamente os significados atribuídos por jovens adultos aos autorretratos postados no Instagram. Foi adotado o método misto sequencial explanatório. Primeiramente, foram contabilizadas e analisadas imagens postadas durante dez dias por 30 homens e 30 mulheres brasileiros, com idades entre 25 e 29 anos. Na fase seguinte, foram entrevistados seis colaboradores, três homens e três mulheres, selecionados a partir da quantidade de fotos postadas no período abordado. A análise estatística evidenciou que a categoria de imagens mais postada por homens e mulheres corresponde à dos autorretratos. A análise temática das entrevistas indicou que o Instagram oferece maior liberdade de exposição e que os participantes sofrem influência do olhar externo. Os significados atribuídos às postagens foram: privacidade, memória, beleza e felicidade. Identidades narrativas imagéticas se constituem e moldam as formas de expressão possíveis na rede, regidas pelos ideais de gênero, beleza e felicidade. A liberdade imaginada nas escolhas biográficas se vê tolhida por um olhar que vigia e curte.
Effect of critical shoulder angle, glenoid lateralization, and humeral inclination on range of movement in reverse shoulder arthroplasty
Authors: Lädermann Alexandre , Tay Eileen , Collin Philippe , Piotton Sébastien , Chiu Chih-Hao , Michelet Aude , Charbonnier Caecilia
Published: August 2019

Objectives

To date, no study has considered the impact of acromial morphology on shoulder range of movement (ROM). The purpose of our study was to evaluate the effects of lateralization of the centre of rotation (COR) and neck-shaft angle (NSA) on shoulder ROM after reverse shoulder arthroplasty (RSA) in patients with different scapular morphologies.

Methods

3D computer models were constructed from CT scans of 12 patients with a critical shoulder angle (CSA) of 25°, 30°, 35°, and 40°. For each model, shoulder ROM was evaluated at a NSA of 135° and 145°, and lateralization of 0 mm, 5 mm, and 10 mm for seven standardized movements: glenohumeral abduction, adduction, forward flexion, extension, internal rotation with the arm at 90° of abduction, as well as external rotation with the arm at 10° and 90° of abduction.

Results

CSA did not seem to influence ROM in any of the models, but greater lateralization achieved greater ROM for all movements in all configurations. Internal and external rotation at 90° of abduction were impossible in most configurations, except in models with a CSA of 25°.

Conclusion

Postoperative ROM following RSA depends on multiple patient and surgical factors. This study, based on computer simulation, suggests that CSA has no influence on ROM after RSA, while lateralization increases ROM in all configurations. Furthermore, increasing subacromial space is important to grant sufficient rotation at 90° of abduction. In summary, increased lateralization of the COR and increased subacromial space improve ROM in all CSA configurations. Cite this article: A. Lädermann, E. Tay, P. Collin, S. Piotton, C-H Chiu, A.

Current trends in hernia surgery in NHS England
Authors: Pawlak M , Tulloh B , de Beaux A
Published: August 2019

Background

Mesh is recommended for the repair of most hernias when prevention of recurrence is the primary endpoint. However, mesh may be associated with increased complications for the patient. The aim of this study was to quantify the use of mesh for abdominal wall hernia surgery in NHS England in recent years.

Materials and methods

The NHS Digital Secondary Uses Service database for 2016/17 and 2017/18 was interrogated for numbers of patient undergoing elective primary hernia surgery. Using the specific hernia code inguinal (T201-9), umbilical (T241-9), incisional (T251-9) and other abdominal wall hernia (T271-9), the use of mesh or suture repair was determined. Recurrent and emergency hernia surgery were excluded. All data were provided by NHS RightCare.

Results

There are almost 100,000 hernia repairs performed annually in NHS England. For every four hernias, three are repaired with mesh. The percentage repaired by mesh varies by hernia type. Mesh repairs in inguinal, umbilical and incisional hernias accounted for 95%, 50% and 82%, respectively.

Conclusions

Mesh repair for all hernia types is more common than suture repair. However, for umbilical and other abdominal wall hernias, a significant proportion are repaired without the use of mesh.
The long-term effects of time use during high school on positive development
Authors: Tjaden Jasper , Rolando Dominique , Doty Jennifer , Mortimer Jeylan
Published: August 2019

This longitudinal study examines how the time that youth spend in activities during high school may contribute to positive or negative development in adolescence and in early adulthood. We draw on data from 1,103 participants in the longitudinal Youth Development Study (Minnesota), followed from entry to high school to their mid-20s. Controlling demographic, socio-economic and psychological influences, we estimate the effects of average time spent on homework, in extracurricular activities and with friends during the four years of high school on outcomes measured in the final year of high school and 12 years after the start. Our results suggest that policies surrounding the implementation and practice of homework may have long-term benefits for struggling students. In contrast, time spent with peers on weeknights was associated with both short- and long-term maladjustment.
The Russian panel study ‘Trajectories in Education and Careers’
Authors: Malik Valeriya
Published: August 2019

This study profile presents the Russian panel study Trajectories in Education and Careers (TrEC). This longitudinal project has been conducted in Russia since 2009 and comprises one national panel and several regional panels of school and university students. The national panel is a longitudinal follow-up with the participants of the Trends in International Mathematics and Science Study (TIMSS) in Russia, who were eighth-grade students in 2011 (aged 13–14) and have been interviewed yearly since then. The unique feature of the national panel is that its respondents also took the tests in the Programme for International Student Assessment (PISA) in 2012, as an additional sample of that study in Russia. The paper gives an outline of TrEC’s progress to date, focusing on its design, data collection and data description. Researchers from all over the world are invited to submit research proposals and analyse TrEC data.
The quarter-life crisis? Precarious labour market status and mental health among 25-year-old in England
Authors: Henderson Morag
Published: August 2019

Despite an increase in living standards and material comforts in industrialised societies, today's ‘emerging adults’ (aged from late teens to mid-to-late 20s) face greater challenges than ever before. The aim of this paper is to explore the relationship between labour market status and mental health for the ‘millennial generation’ in England, and whether it varies by gender and ethnicity. This study will be the first to draw on the results from the 2015 sweep of Next Steps data when the sample members are aged 25 and, together with the previous seven sweeps, bring the debate up to date by providing first estimates of the life condition of contemporary emerging adults. We find black and minority ethnic groups have lower odds of reporting mental ill-health at age 25 than the white group. With respect to labour market status, we find that net of socio-economic characteristics, educational attainment, behavioural variables and income at age 25, those who are unemployed are more than twice as likely to report symptoms of poor mental health as those who are employed. Shift workers and those on zero-hours contracts are also at a greater risk of mental ill-health by 47% and 44% respectively than those who are not shift workers or zero-hours workers. We find no significant difference for those who have a second job or are on a permanent contract for mental health at age 25 compared to those who do not have a second job or are on a temporary contract.
Young people and the Great Recession: Variations in the school-to-work transition in Europe and the United States
Authors: Schoon Ingrid , Bynner John
Published: August 2019

This paper reviews evidence on young people in Europe and the US making the transition from school-to-work before and after the 2008 Great Recession. Taking a macro-level perspective, similarities and differences in education and employment experiences across different European countries are described, considering the role of different institutional support systems in ‘scaffolding’ young people's transitions to independence. It is argued that the 2008 financial crisis brought with it reduced employment opportunities for young people and accelerated pre-existing trends towards prolonged education participation and precarious employment. There are, however, considerable variations across different countries, highlighting the role of social institutions in supporting young people during the school-to-work transition. Transition systems that created bridges between education and employment are associated with lower national levels of youth unemployment, while young people coming of age in less-protective transition regimes suffered highest levels of youth unemployment, high levels of temporary employment and not being in education, employment or training (NEET).
A reassessment of socio-economic gradients in child cognitive development using growth mixture models
Authors: Sindall Katy , Sturgis Patrick , Steele Fiona , Leckie George , French Rob
Published: August 2019

Recent social and educational policy debate in the UK has been strongly influenced by studies that have found children’s cognitive developmental trajectories to be significantly affected by the socio-economic status of the households into which they were born. Most notably, using data from the 1970 British cohort study, Feinstein (2003) concluded that children from less-advantaged backgrounds who scored high on cognitive tests at 22 months had been overtaken by age seven by children from more advantaged origins, who had scored lower on the baseline test. However, questions have been raised about the methodological robustness of these studies, particularly the possibility that their key findings are, at least in part, an artefact of regression to the mean. In this paper, we assess growth mixture models as an alternative approach for identifying and explaining cognitive developmental trajectories in children which is robust to regression to the mean. We apply this approach to children’s cognitive test score data from the Millennium Cohort Study. Our findings provide no support for the contention that more initially able children from disadvantaged backgrounds are ‘overtaken’ in cognitive development by less initially able children from more affluent backgrounds. We do, however, find that cognitive developmental trajectories are related to socio-economic status, such that initial class-based inequalities increase over time.
Explaining disparities in transitions among visual-functioning states
Authors: Liew Hui
Published: August 2019

Visual impairment is one of the most common disabilities among older adults and the majority of the visually impaired and blind worldwide are those aged 50 and older. This study aims to examine whether transitions across different visual-functioning states (good and better to poor) among older adults in the United States reflect the processes associated with double-jeopardy intersectionality, cumulative advantage (disadvantage), persistent inequality and age-as-leveller. The empirical work of this study is based on the 2002–14 Health and Retirement Study (HRS). Multistate life tables are used to assess the aim of the study. Findings from multistate life tables reveal higher transition probabilities associated with vision deterioration among females, black people, Hispanic people and those with less than a four-year degree. Findings provide support for both the intersectionality hypothesis in conjunction with the cumulative advantage (disadvantage) and persistent inequality hypothesis. Targeted interventions that detect visual loss and prevent vision impairment as well as the provision of appropriate and accessible refraction and surgical services should begin early on in life and should continue to focus on the specific needs of ethnic minorities, females and those with low education. Understanding how individuals move through different visual-functioning states and identifying the risk factors for poor vision are relevant to many policy concerns that seek to reduce the disease burden or health consequences associated with visual impairment.
Economic roles and marriage timing: A cohort comparison between women and men in East and West Germany
Authors: Müller Nora , Dräger Jascha
Published: August 2019

Over recent decades, we have seen a delay of marriage and simultaneously an expansion of the educational system and massive changes in the labour market in most Western countries. In this paper, we link these phenomena within the unique historical context of the Federal Republic of Germany (FRG) and the former German Democratic Republic (GDR). Making use of data from the German National Educational Panel Study (NEPS), we analyse the associations between individuals’ current economic roles –full- and part-time employed, unemployed, enrolment in education or training– and the timing of their first marriage for men and women born between 1944 and 1986 in the former FRG and GDR. We find that full-time employees are most likely to enter first marriage, while being unemployed or enrolled in education are associated with a delay of first marriage. However, there are crucial differences by gender, region and birth cohort. Women are more likely to marry when they finish education, while for men it seems to be more important to find gainful employment. These associations rarely change over birth cohorts in West Germany. In East Germany, the situation differs significantly. For the older (pre-reunification) cohorts, we find almost no associations between economic roles and marriage timing. For the younger (post-reunification) cohorts, we find convergence to the West German patterns.

Published: August 2019

The LIVES-FORS Cohort Study (LCS) is a longitudinal annual survey following a cohort of young adults born between 1988 and 1997 who grew up in Switzerland (initial N = 1,691). The LCS was launched in 2013 and complements the Swiss Household Panel (SHP) by over-representing the second generation of immigrants (‘secondos’). The principal aim of the study is to observe the transition into adulthood with a focus on the life course and on vulnerability processes, comparing participants whose parents arrived in Switzerland as adults to participants whose parents have grown up in Switzerland. The LCS provides rich data both on the factual (such as education, employment and financial situation) and on the self-judgement (well-being, personality and health, for example) dimensions of respondents’ lives. The first wave of the LCS used a life-history calendar to collect information on each respondent’s past life trajectory. In this first wave, several life trajectories were investigated (residence, cohabitation, couple’s relationship, family, activities and health). This paper provides an overview of the LCS with a specific focus on the first four waves (the last data were released in December 2017).

They determine the probability distributions on this interval.
It is proved that the set of all transformations is infinite and forms a non-commutative group with respect to the operation of a composition (superposition).
Thus, a group of probability distributions is constructed on the interval.
These distributions have non-trivial local properties (self-similar structure).
Bursts with High and Low Load of Epileptiform Spikes Show Context-Dependent Correlations in Epileptic Mice

Published: August 2019

Hypersynchronous network activity is the defining hallmark of epilepsy and manifests in a wide spectrum of phenomena, of which electrographic activity during seizures is only one extreme. The aim of this study was to differentiate between different types of epileptiform activity (EA) patterns and investigate their temporal succession and interactions. We analyzed local field potentials (LFPs) from freely behaving male mice that had received an intrahippocampal kainate injection to model mesial temporal lobe epilepsy (MTLE). Epileptiform spikes occurred in distinct bursts. Using machine learning, we derived a scale reflecting the spike load of bursts and three main burst categories that we labeled high-load, medium-load, and low-load bursts. We found that bursts of these categories were non-randomly distributed in time. High-load bursts formed clusters and were typically surrounded by transition phases with increased rates of medium-load and low-load bursts. In apparent contradiction to this, increased rates of low-load bursts were also associated with longer background phases, i.e., periods lacking high-load bursting. Furthermore, the rate of low-load bursts was more strongly correlated with the duration of background phases than the overall rate of epileptiform spikes. Our findings are consistent with the hypothesis that low-level EA could promote network stability but could also participate in transitions towards major epileptiform events, depending on the current state of the network.
Neonatal Injury Alters Sensory Input and Synaptic Plasticity in GABAergic Interneurons of the Adult Mouse Dorsal Horn
Authors: Li Jie , Baccei Mark L.
Published: August 2019

Neonatal tissue injury disrupts the balance between primary afferent-evoked excitation and inhibition onto adult spinal projection neurons. However, whether this reflects cell-type-specific alterations at synapses onto ascending projection neurons, or rather is indicative of global changes in synaptic signaling across the mature superficial dorsal horn (SDH), remains unknown. Therefore the present study investigated the effects of neonatal surgical injury on primary afferent synaptic input to adult mouse SDH interneurons usingin vitropatch-clamp techniques. Hindpaw incision at postnatal day (P)3 significantly diminished total primary afferent-evoked glutamatergic drive to adult Gad67-GFP and non-GFP neurons, and reduced their firing in response to sensory input, in both males and females. Early tissue damage also shaped the relative prevalence of monosynaptic A- versus C-fiber-mediated input to mature GABAergic neurons, with an increased prevalence of Aβ- and Aδ-fiber input observed in neonatally-incised mice compared with naive littermate controls. Paired presynaptic and postsynaptic stimulation at an interval that exclusively produced spike timing-dependent long-term potentiation (t-LTP) in projection neurons predominantly evoked NMDAR-dependent long-term depression in naive Gad67-GFP interneurons. Meanwhile, P3 tissue damage enhanced the likelihood of t-LTP generation at sensory synapses onto the mature GABAergic population, and increased the contribution of Ca2+-permeable AMPARs to the overall glutamatergic response. Collectively, the results indicate that neonatal injury suppresses sensory drive to multiple subpopulations of interneurons in the adult SDH, which likely represents one mechanism contributing to reduced feedforward inhibition of ascending projection neurons, and the priming of developing pain pathways, following early life trauma.

SIGNIFICANCE STATEMENTMounting clinical and preclinical evidence suggests that neonatal tissue damage can result in long-term changes in nociceptive processing within the CNS. Although recent work has demonstrated that early life injury weakens the ability of sensory afferents to evoke feedforward inhibition of adult spinal projection neurons, the underlying circuit mechanisms remain poorly understood. Here we demonstrate that neonatal surgical injury leads to persistent deficits in primary afferent drive to both GABAergic and presumed glutamatergic neurons in the mature superficial dorsal horn (SDH), and modifies activity-dependent plasticity at sensory synapses onto the GABAergic population. The functional denervation of spinal interneurons within the mature SDH may contribute to the “priming” of developing pain pathways following early life injury.
CIUDADES COMPACTAS Y VERDES: DISCUSIONES SOBRE LA CALIDAD DE VIDA Y LA SOSTENIBILIDAD URBANA

Published: August 2019

El presente artículo hace un análisis de los aspectos positivos y negativos del modelo compacto, valiéndose de una comparación entre este y los principales planteamientos de la propuesta estadounidense denominada “smart growth” (crecimiento inteligente). El objetivo principal de la investigación fue explorar los dos modelos, estableciendo el impacto urbano que cada uno ha tenido sobre la naturaleza, el consumo de energía, el agotamiento de los espacios naturales y sobre la misma calidad de vida de los habitantes. En términos metodológicos, se tomaron como punto de partida algunas de las hipótesis que se han estructurado con base en la teoría disponible, así como ciertos índices de compactación urbana, utilizados internacionalmente. Mediante simulaciones se obtuvieron conclusiones relativas a la disponibilidad y accesibilidad de elementos cualitativos urbanos. Este método también permitió identificar la percepción que tiene la comunidad de dichos elementos. Los resultados obtenidos muestran que si bien en algunos casos los indicadores cuantitativos y cualitativos de un modelo urbano más expansivo pueden parecer mejores por la cantidad de espacio disponible (por ejemplo, áreas verdes), una aplicación más eficiente de estos se puede observar en un modelo más compacto, dado que esposible una mejor distribución de los espacios, correctamente dimensionados y oportunamente accesibles, para así optimizar su potencial de uso.

Nile tilapia (Oreochromis niloticus) is one of the most cultivated and economically important species in world aquaculture. Intensive production promotes the use of monosex animals, due to an important dimorphism that favors male growth. Currently, the main mechanism to obtain all-male populations is the use of hormones in feeding during larval and fry phases. Identifying genomic regions associated with sex determination in Nile tilapia is a research topic of great interest. The objective of this study was to identify genomic variants associated with sex determination in three commercial populations of Nile tilapia. Whole-genome sequencing of 326 individuals was performed, and a total of 2.4 million high-quality bi-allelic single nucleotide polymorphisms (SNPs) were identified after quality control. A genome-wide association study (GWAS) was conducted to identify markers associated with the binary sex trait (males = 1; females = 0). A mixed logistic regression GWAS model was fitted and a genome-wide significant signal comprising 36 SNPs, spanning a genomic region of 536 kb in chromosome 23 was identified. Ten out of these 36 genetic variants intercept the anti-Müllerian (Amh) hormone gene. Other significant SNPs were located in the neighboring Amh gene region. This gene has been strongly associated with sex determination in several vertebrate species, playing an essential role in the differentiation of male and female reproductive tissue in early stages of development. This finding provides useful information to better understand the genetic mechanisms underlying sex determination in Nile tilapia.
Legal Characters of Partnership Agreement 212 Mart
Authors: Mulhadi Mulhadi , Sembiring Zulkifli
Published: August 2019

AbstractBased on partnership principles, partnership agreements can take place when one or more people have the same interests and awareness to work together to achieve common interests. Although the national economic conditions are currently experiencing a significant decline with low public purchasing power, which is marked by the many closures of retail businesses, but the desire to build a business in the form of partnership in this sector in certain groups of people is still showing encouraging development. One of them is the spirit of partnership in the establishment of 212 Mart Supermarkets in Indonesia, especially Medan City. This study uses a normative juridical approach, which is nature descriptive because it seeks to explain clearly the pattern of the agreement of establishing 212 Mart supermarkets, where the population is 218 agreement documents. The sample selection was determined purposively because of the form and content of the same agreement from each investor from several 212 Mart Supermarkets that had been established in Medan City. Based on research shown that partnership agreement 212 Mart has several legal characters namely that partnership agreement 212 mart was identified as an unnamed (anonymous) agreement, reciprocal agreement, as an agreement which gave birth to new partnerships, and jamaat-based agreements.Keywords: legal characters, partnership, agreement, 212 Mart

Published: August 2019

The applicability of gas chromatography–triple quadrupole mass spectrometry (GC–MS/MS) for determination of dioxins in soil was investigated. The analytical method was validated based on US Environmental Protection Agency (EPA) Method 1613 and European Union (EU) Regulation No. 709/2014 for selectivity, linearity of sensitivity, and instrumental limits of quantification (iLOQs). Method development commenced with determination of retention times for 17 native polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) and selection of characteristic ions from GC–MS/MS spectra. The linearity was measured using 1613 standard solutions (CS1–CS5) containing 0.5 to 200 ng/mL tetrachlorodibenzo-p-dioxin/furan (TCDD/F) congeners, 2.5 to 1000 ng/mL pentachlorodibenzo-p-dioxin/furan (PeCDD/F) to heptachlorodibenzo-p-dioxin/furan (HpCDD/F) congeners, and 20 to 2000 ng/mL octachlorodibenzo-p-dioxin/furan (OCDD/F) congeners. The correlation coefficient (R2) values ranged between 0.9990 and 0.9999, and the iLOQ values ranged from 0.052 to 0.350 pg/μL for TCDD/F congeners, with a relative standard deviation of 2.7–9.6%. The entire analytical method was verified by analysis of certified reference materials (BCR-529 and BCR-530), and the recoveries were 71.79–103.87% and 81.50–103.12%, respectively. Thus, the GC–MS/MS system provides an alternative to GC–high-resolution MS for the simultaneous determination of TCDD/F congeners in soil.
A História da Religião na Filosofia Positiva de Schelling – a tese tillichiana de 1910
Authors: Calvani Carlos Eduardo Brandão
Published: August 2019

A obra de Paul Tillich é fortemente influenciada pela filosofia de Friedrich Schelling. O doutorado em Filosofia de Tillich, defendido em 1910 na Universidade de Breslau evidencia seu interesse nesse autor. Intitulado “A história da religião na Filosofia Positiva de Schelling”, a tese de 1910 só foi publicada em 1974, em inglês, com tradução de Victor Nuovo. Embora seja um texto de juventude, nele se enuncia um estilo de escrita que acompanhará o posterior amadurecimento de Tillich, bem como temas que serão aprofundados ao longo de sua trajetória, tais como a importância da história, da mitologia, a busca por identidade, o símbolo da queda, a encarnação e a profundidade da mensagem cristã como revelação da possibilidade de harmonização entre o ser humano e o Absoluto. O presente artigo apresenta um resumo dessa tese, com considerações pontuais que identificam elementos que posteriormente serão desenvolvidos por Tillich, e é resultado de um projeto de IC (Iniciação Científica) coordenado pelo autor principal e acompanhado pelo discente que providenciou a tradução da tese de 1910.Abstract The work of Paul Tillich is strongly influenced by the philosophy of Friedrich Schelling. Tillich’s doctorate in philosophy, defended in 1910 at the University of Breslau evidences his interest in this author. Entitled "The History of Religion in Schelling's Positive Philosophy," the 1910 thesis was only published in 1974, in English, with translation by Victor Nuovo. Although it is a text of his youth, it already enunciates a style of writing that will accompany the later maturation of Tillich’s work, with themes that will be deepened along his trajectory, such as the importance of history, mythology, the search for identity, the symbol of the fall, the incarnation and depth of the Christian message as revelation of the possibility of harmonization between humanity and the Absolute. The present article presents a summary of Tillich’s thesis, with specific considerations that identify elements that will later be developed by Tillich, and is the result of an IC project (Scientific Initiation) coordinated by the main author of this article and accompanied by the student who provided the translation of the 1910 thesis.

A proposta de gestão do trabalho da Fundação Estatal Saúde da Família (FESF-SUS, n.d.) incluiu os seguintes aspectos: remuneração variável, mobilidade do trabalhador entre os municípios e fatores associados ao suprimento de médicos. A complexidade dessa proposta se depara com a ausência de experiência na gestão desse modelo e também com as questões estruturais e institucionais que marcaram historicamente a gestão do trabalho nos municípios.

Resumo Este artigo tem por objetivo explicar relações entre os investimentos em pesquisa e desenvolvimento (P&D) e os resultados da inovação entre os anos de 2009 e 2013 em empresas beneficiárias dos incentivos para inovação tecnológica da Lei n. 11.196 (2005) - a chamada Lei do Bem. São estimados modelos econométricos logit para efeitos fixos e modelos de probabilidade linear com efeitos fixos. Os resultados indicam que a probabilidade das beneficiárias inovarem em produtos, processos ou serviços, ou apenas em produtos, depende do tamanho da empresa e do montante investido em P&D, principalmente em recursos humanos (RH). As chances das empresas inovarem em processos se relacionam ao tamanho da empresa, aos gastos e aos programas de desenvolvimento de RH. Logo, os resultados confirmam que os investimentos em P&D das beneficiárias geram resultados de inovação tecnológica.

Resumo Este artigo apresenta uma investigação acerca da influência que as variáveis de background familiar (escolaridade do pai, escolaridade da mãe e renda familiar) exercem sobre o desempenho de um estudante, candidato às vagas dos processos de seleção em uma instituição de Ensino Técnico Federal brasileira. A pesquisa consistiu em analisar a influência do background familiar, como determinante de desempenho do aluno, no acesso ao Ensino Técnico Profissional brasileiro. Para conduzir essa investigação foram utilizados dados secundários, totalizando 19.226 observações. Buscando alcançar o objetivo proposto, formulou-se um modelo conceitual composto por 3 hipóteses. Os resultados são apresentados em 3 etapas: etapa I - separação dos campi em clusters; etapa II - análise das regressões múltiplas; e etapa III - análise das regressões logísticas. As hipóteses 1 e 2 foram confirmadas e a Hipótese 3, refutada. Os resultados apresentaram um efeito positivo das variáveis renda familiar e escolaridade do pai, mas sem significância estatística para a variável escolaridade mãe.
Identifying public policies: Public Defenders and men who broke the Maria da Penha Law
Authors: Vidal Josep Pont
Published: August 2019

Resumo A avaliação dos serviços de assistência prestados pela Defensoria Pública possibilita a identificação de demandas e problemas que constituirão a origem de futuras políticas públicas. Este artigo apresenta os resultados de uma observação na qual se avaliaram os serviços de assistência prestados pelo Núcleo de Atendimento ao Homem Autor de Violência Doméstica e Familiar (Neah), a partir de depoimentos dos assistidos e de suas companheiras. Como resultado, identificam-se futuros serviços e políticas públicas voltados à prevenção, autorreflexão e mudança de percepção dos homens agressores. Os resultados da observação empírica ressaltam o paradoxo das políticas públicas de atendimento a homens acusados de violência doméstica: enquanto a avaliação dos serviços de assistência prestados pela DP-PA e do atendimento policial por parte das mulheres cônjuges manifesta uma insatisfação pelos resultados do atendimento recebido na DP-PA, com relação aos seus parceiros. Os homens que participaram do grupo terapêutico manifestaram nas entrevistas haver experimentado uma mudança de comportamento com relação às suas cônjuges e sobre a visão da mulher.

Published: August 2019

Resumen Este artículo ofrece un panorama del estado de la investigación latinoamericana sobre cooperación intermunicipal, un fenómeno que ha adquirido relevancia empírica en la región desde la década de los años noventa. A partir de una revisión sistemática de la literatura y del análisis de contenido de 47 artículos publicados entre 2005 y 2016 en revistas indexadas en WOS, Scopus y LatinIndex, este trabajo informa acerca de los avances de la investigación sobre los condicionantes relevantes, las complejidades de la operación y los diferentes efectos de la cooperación intermunicipal en países de América Latina. Los resultados identifican las brechas de investigación en el estudio de las causas y los factores explicativos de la colaboración como modelo organizacional y gobernanza territorial, como también la falta de estudios de efectividad de dichos arreglos. La identificación de estas brechas permitirá orientar la agenda de investigación futura sobre cooperación entre municipios.
The three types of power distribution, that structure decentralization in South America

Resumen Es común en las investigaciones sobre el Estado y la administración pública realizar un análisis de su estructura, función, forma y tipo. Sin embargo, en algunas oportunidades estas categorías generales no revelan la distribución de potestades o poder real ejercido en los distintos niveles territoriales. En este trabajo se propone, a través de una revisión histórico-institucional de los últimos 50 años en países de América del Sur, verificar la existencia de estructuras de poder características que permanecen en el tiempo con cambios graduales que mantienen la esencia de su origen histórico y otras que se forman producto de cambios disruptivos que modifican los paradigmas dominantes. La existencia de estas estructuras arroja tres tipos característicos que, denominamos compuesto, integrado y simple.
Cashew crop propagation

Published: August 2019

Abstract The cashew tree, a genuinely Brazilian fruit tree, is grown mainly because of its nuts and cashew nut shell liquid (CNSL), widely used in industry. Of great food importance, the cashew apple also presents economic representativeness in Brazil. With great variability, the culture has recently begun researches for improvement, with selection of new clones, more productive and with specific purpose. Usually propagated from seeds to produce new orchards, which has been replaced by vegetative propagation using the seed only for rootstocks production. Vegetative propagation by lateral grafting is the mainly technique used to multiplicated this crop, but various clonal propagation techniques, such air layering and tissue culture have been attempted. The last one, however, needs further studies because of their high costs.

Abstract Banana farming has an important position in Brazilian agricultural production. This position was earned due to the use of cultivation technologies and adequate fertilization made through recommendations of evaluation of foliar analyzes. The objective of this study was to determine the seasonality of the nutritional status of the diagnostic leaf during the development of banana tree. The experiments took place in the city of Sete Barras / SP, with cultivars such as Grande naine and Prata, on summer and winter. It was evaluated the influence of the collection of the diagnostic leaf in the stations, in six seasons during the development of the banana bunch and it was compared with the standard sampling. The values were submitted to analysis of variance, and when the F was significant, a comparison of means was performed. The sampling stations and the collection stages influence the nutrient behavior in the diagnostic leaf of both varieties, with exceptions for Mg and Mn. The average levels of nutrients during the collection stages showed no difference among the 1st, 2nd, 3rd and 4th (standard). Even for the ‘Prata’ and Grande Naine banana plants cultivated in the Ribeira Valley, there is no significant alteration in the nutrient content of the foliage among the 1st to 4th stages, allowing an increasing of collection for foliar tissue analysis.

Abstract There are several banana cultivars resistant to Black Sigatoka disease and to Panama disease, but due to the lack of information regarding post-harvest characteristics, many are rejected in the market. Nitrogen and potassium fertilization may help to improve the sensory characteristics of ripe banana, but there is lack of studies on its effects on banana cultivation, especially those resistant to diseases. The aim of this study was to evaluate the post-harvest characteristics of ‘Prata-Anã’, ‘BRS Platina’ and ‘PA94-01’ banana cultivars at four N and K2O fertilization levels (NK0: no fertilization, NK1: 175 and 285 kg ha-1 year-1, NK2: 350 and 570 kg ha-1 year-1, NK3: 525 and 855 kg ha-1 year-1, respectively) in three production cycles. It could be concluded that N and K doses adopted in this work did not influence the post-harvest physicochemical characteristics of ‘Prata-Anã’, ‘BRS Platina’ and ‘PA94-01’ banana cultivars. Regardless of N and K doses, ‘Prata-Anã’, ‘BRS Platina’ and PA94-01’ banana cultivars presented differences regarding post-harvest physicochemical characteristics. Production cycles did not influence the physical characteristics but differed in post-harvest chemical characteristics in ‘Prata-Anã’, ‘BRS Platina’ and ‘PA94-01’ banana cultivars.

Abstract Objective: To investigate whether quantitative computed tomography (CT) measurements can predict microvascular invasion (MVI) in hepatocellular carcinoma (HCC). Materials and Methods: This was a retrospective analysis of 200 cases of surgically proven HCCs in 125 consecutive patients evaluated between March 2010 and November 2017. We quantitatively measured regions of interest in lesions and adjacent areas of the liver on unenhanced CT scans, as well as in the arterial, portal venous, and equilibrium phases on contrast-enhanced CT scans. Enhancement profiles were analyzed and compared with histopathological references of MVI. Univariate and multivariate logistic regression analyses were used in order to evaluate CT parameters as potential predictors of MVI. Results: Of the 200 HCCs, 77 (38.5%) showed evidence of MVI on histopathological analysis. There was no statistical difference between HCCs with MVI and those without, in terms of the percentage attenuation ratio in the portal venous phase (114.7 vs. 115.8) and equilibrium phase (126.7 vs. 128.2), as well as in terms of the relative washout ratio, also in the portal venous and equilibrium phases (15.0 vs. 8.2 and 31.4 vs. 26.3, respectively). Conclusion: Quantitative dynamic CT parameters measured in the preoperative period do not appear to correlate with MVI in HCC.
