Authors: Rocha Andréa Ferretto , Handem Abdel Correia , Filho Mario Luiz Biazzetti , Stech Marcia Regina , Figueiredo Mario Roberto Chim 
Published: November 2019

Um estudo foi realizado com o objetivo de avaliar as características seminais do cará Geophagus brasiliensis mantido em cativeiro com e sem indução hormonal. Para tanto, foram utilizados 26 machos distribuídos entre os seguintes tratamentos: nove machos sem indução hormonal; nove machos com indução hormonal de extrato de hipófise de carpa (HC) e oito machos com indução hormonal por gonadotropina coriônica humana (HCG). Os parâmetros avaliados para a caracterização seminal nos diferentes tratamentos foram volume seminal, cor do sêmen, motilidade espermática, vigor espermático, tempo de latência, concentração espermática e viabilidade espermática. Os dados foram submetidos à análise de variância com 95% de confiança. A coloração do sêmen foi classificada como branco leitoso. Os valores médios para a motilidade, vigor espermático e concentrações dos espermatozoides foram: 94,44%, 78,75% e 63,88%; 4,44, 4,00 e 3,55; 5,10, 5,00 e 5,72 x 109 mL-1, para os tratamentos sem indução, HCG e HC, respectivamente. O tempo de latência espermático variou de 143,4 a 988,2 segundos e a viabilidade espermática foi de 100% para todos os tratamentos. A análise de variância não apresentou diferença significativa entre os efeitos dos diferentes tratamentos sobre nenhum dos parâmetros avaliados. Embora os resultados tenham demonstrado não ser necessária a indução artificial de machos durante o período reprodutivo, outros protocolos de reprodução artificial devem ser testados para G. brasiliensis vislumbrando o uso da espécie de forma comercial na aquicultura.
Accretion Kinematics in the T Tauri Binary TWA 3A: Evidence for Preferential Accretion onto the TWA 3A Primary
Authors: Tofflemire Benjamin M. , Mathieu Robert D. , Johns-Krull Christopher M. 
Published: November 2019

Abstract
We present time-series, high-resolution optical spectroscopy of the eccentric T Tauri binary TWA 3A. Our analysis focuses on variability in the strength and structure of the accretion-tracing emission lines Hα and He i 5876 Å. We find emission line strengths to display the same orbital phase–dependent behavior found with time-series photometry, namely, bursts of accretion near periastron passages. Such bursts are in good agreement with numerical simulations of young eccentric binaries. During accretion bursts, the emission of He i 5876 Å consistently traces the velocity of the primary star. After removing a model for the system’s chromospheric emission, we find the primary star typically emits ∼70% of the He i accretion flux. We interpret this result as evidence for circumbinary accretion streams that preferentially feed the TWA 3A primary. This finding is in contrast to most numerical simulations, which predict the secondary should be the dominant accretor in a binary system. Our results may be consistent with a model in which the precession of an eccentric circumbinary disk gap alternates between preferentially supplying mass to the primary and secondary.
On the GeV Emission of the Type I BdHN GRB 130427A

Abstract
We propose that the inner engine of a type I binary-driven hypernova (BdHN) is composed of Kerr black hole (BH) in a non-stationary state, embedded in a uniform magnetic field B
0 aligned with the BH rotation axis and surrounded by an ionized plasma of extremely low density of 10−14 g cm−3. Using GRB 130427A as a prototype, we show that this inner engine acts in a sequence of elementary impulses. Electrons accelerate to ultrarelativistic energy near the BH horizon, propagating along the polar axis, θ = 0, where they can reach energies of ∼1018 eV, partially contributing to ultrahigh-energy cosmic rays. When propagating with

through the magnetic field B
0, they produce GeV and TeV radiation through synchroton emission. The mass of BH, M = 2.31M
⊙, its spin, α = 0.47, and the value of magnetic field B
0 = 3.48 × 1010 G, are determined self consistently to fulfill the energetic and the transparency requirement. The repetition time of each elementary impulse of energy

erg is ∼10−14 s at the beginning of the process, then slowly increases with time evolution. In principle, this “inner engine” can operate in a gamma-ray burst (GRB) for thousands of years. By scaling the BH mass and the magnetic field, the same inner engine can describe active galactic nuclei.
Mondialisation des réseaux d’acteurs de l’artisanat dans l’arrière-pays marocain
Authors: Bouaabid Hanane 
Published: November 2019

L’activité de tissage dans les arrière-pays marocains subit de profondes transformations en raison de sa marchandisation et de son internationalisation. Le réseau d’acteurs impliqué se développe et se spécialise en jouant un rôle de « traduction » au sens de la théorie de l’acteur-réseau. Cela se fait au détriment des femmes-tisseuses qui se trouvent dans une situation de plus grande dépendance.
Gouvernance politique, diversité du genre et transition démocratique : leçons tunisiennes
Authors: Kchouk Bilel , Ben Rhouma Amel 
Published: November 2019

Le rapport entre transition démocratique et percée des femmes dans la gouvernance politique constitue un objet de recherche prolifique dans la littérature politiste. Les résultats sont pourtant divergents. Pour les uns, la transition démocratique favoriserait l’évolution de la place des femmes dans les instances du pouvoir politique. Pour d’autres, il n’existe pas nécessairement de lien entre ces deux phénomènes, parfois même la transition nuirait à la représentativité des femmes.	Notre recherche qui porte sur la Tunisie entre 2011 et 2016, procède selon trois logiques : une analyse statistique de l’évolution genrée du pouvoir politique depuis la chute du régime autoritaire de Ben Ali ; une étude sociographique des femmes dans les postes décisionnaires ; et un examen des perceptions de ces mêmes élites féminines sur leur place dans le nouvel échiquier politique. La confrontation des résultats de notre étude quantitative et qualitative montre qu’en dépit d’une évolution quantitative positive au sein du gouvernement et du parlement ainsi que d’une diversification sociologique de ces femmes politiques, ces dernières, très fréquemment, jugent la transition démocratique négativement en termes de représentation des femmes.
Du mouvement des droits de l’enfant à la mise en place de politiques de protection en Argentine (1989-2005)
Authors: Grimberg Julieta 
Published: November 2019

Cet article s’intéresse à la diffusion et à l’appropriation du discours des droits de l’enfant en Argentine. Dans ce but, il reconstruit dans un premier temps la création d’un mouvement local pour les droits de l’enfance, en identifiant les critiques faites par les nouveaux activistes au « système tutélaire » de protection en vigueur, en analysant l’usage particulier qu’ils font de la Convention des droits de l’enfant de 1989. Ensuite, l’article explore le processus de mise en place des nouvelles politiques basées sur la perspective de la « protection intégrale des droits de l’enfant » dans la ville de Buenos Aires ; un territoire où coexistent lois nationales et locales issues de visions divergentes de ce qu’est un enfant en danger et de ce que signifie la protection de ses droits. En mettant la focale sur ce processus, l’article analyse les conflits et luttes de pouvoir qui traversent les rapports entre institutions administratives et judiciaires du champ de la protection de l’enfance et montre que les droits de l’enfant ont été l’objet d’interprétations et d’instrumentalisations diverses.
Trois continents et une île
Authors: Fejtö François 
Published: November 2019

Dans cette Lettre de la Havane , l’histoirien François Fejtö décrit avec un certain sarcasme l’envers du décor de la Conférence de la Havane – la « Tricontinentale », qui pris place à Cuba du 3 au 15 janvier 1966. Du luxueux décor – destiné à l’origine aux touristes américains – aux différentes tensions qui traversent les mouvements tiers-mondistes d’alors, l’historien décrit à la fois adroitement et précisément les dissensions entre les mouvements qui composent les participants, mais aussi leurs rapports avec chacun des « frères ennemis » ; les Soviétiques et les Chinois. L’éviction ou du moins l’isolement de ces derniers semblait avoir été, au départ, un des objectifs de la conférence pour l’URSS –. Fetjö relate également les débats relatifs à la création d’une organisation tricontinentale, dont les bases sont alors jetées, qui conserve pourtant l’appareil de l’ancienne organisation, fondée sur la coopération asiatico-africaine. Ce texte apporte enfin des éléments de compréhension importants pour saisir les différentes tensions suivant le départ du Che de Cuba en 1965 – qui provoqua une crise du castrisme, bloquée entre intérêts des régimes révolutionnaires stabilisés, en voie d’embourgeoisement, et la pression des « révoltés inassouvis », exaspérés par les progrès du « colonialisme », qui « exigent une aide quasi illimitée, sacrifice sur sacrifice ».

Published: November 2019

BACKGROUND AND OBJECTIVE:
To evaluate the retinal and vasculature changes in infants with congenital Zika syndrome (CZS) using fluorescein angiography (FA).

PATIENTS AND METHODS:
This consecutive case series included six infants with CZS. FA and color fundus imaging were performed under general anesthesia in both eyes of all infants using a contact widefield digital imaging system. All color fundus images were obtained using a 130° field of view lens, and the FA images were captured using either a 130° or 80° field of view lens. The immunoglobulin M antibody capture enzyme-linked immunosorbent assay was positive for Zika virus in the cerebrospinal fluid samples of all infants. Other congenital infections were ruled out.

RESULTS:
The mean ± standard deviation age of the infants at the time of examination was 1.4 years ± 0.1 years (range: 1.3 years to 1.5 years). Contact fundus photographs showed macular abnormalities in seven eyes (58%) and retinal vasculature changes in two eyes (17%). FA detected macular abnormalities in all 12 eyes (100%) and retinal vasculature changes in five eyes (42%). The main retinal vasculature changes were peripheral avascularity in five eyes (42%) and microvasculature abnormalities in three eyes (25%).

CONCLUSION:
FA may be an important tool for detecting subtle macular and retinal vasculature changes in CZS.

Complete Posterior Vitreous Detachment Reduces the Need for Treatment of Diabetic Macular Edema
Authors: Anderson William , Piggott Kisha , Bao Yicheng K. , Pham Hang , Kavali Sweta , Rajagopal Rithwick 
Published: November 2019

BACKGROUND AND OBJECTIVE:
To evaluate the vitreomacular interface and its relation to treatment burden for diabetic macular edema (DME) in patients without overt vitreomacular traction (VMT).

PATIENTS AND METHODS:
A retrospective cohort study of 494 eyes from 274 patients who had macular spectral-domain optical coherence tomography (SD-OCT) and did not have proliferative diabetic retinopathy, DME, or VMT at the initial visit. Posterior vitreous detachment (PVD) was categorized at the initial visit into five stages (0–4) using SD-OCT parameters alone.

RESULTS:

Two of 34 eyes (6.9%) presenting with a complete PVD required DME treatment during follow-up, whereas 144 of 460 eyes (31.3%) without a complete PVD at baseline required treatment (
P
= .001, Chi-squared). After adjusting for age, ethnicity, gender, and HbA1c, complete PVD at baseline was associated with a significant reduction in risk of DME therapy (hazard ratio: 0.18; 95% confidence interval, 0.05–0.73;
P
= .02).

CONCLUSION:
Complete PVD is independently associated with a reduced need for DME treatment.

Comparison of Observation Versus Vitrectomy for Patients With Hemorrhagic Posterior Vitreous Detachment
Authors: Mason Lauren B. , Wilhite James B. , McGwin Gerald , Swain Thomas A. , Crosson Jason N. 
Published: November 2019

BACKGROUND AND OBJECTIVE:
Patients with hemorrhagic posterior vitreous detachments (HPVDs) have a high rate of retinal tears and often develop retinal detachments (RDs). This study aims to compare outcomes of 25-gauge pars plana vitrectomy (PPV) for HPVD versus an observational group.

PATIENTS AND METHODS:
Retrospective cohort study of 109 consecutive eyes of 105 patients diagnosed with HPVD; 66 eyes underwent PPV and 43 eyes were observed.

RESULTS:

Twenty-four eyes (36.4%) in the surgical group were found to have tears intraoperatively not seen preoperatively. The median time to vitreous hemorrhage (VH) resolution was significantly shorter for the PPV group, 14 days (interquartile range [IQR]: 7 days to 35 days), compared to those who were observed, 58.5 days (IQR: 30 days to 91 days) (
P
< .0001). RDs occurred more frequently among observational patients (11.63%) compared to 1.52% of surgical patients (
P
= .0344).

CONCLUSION:
Twenty-five-gauge PPV for HPVD resulted in less RDs, diagnosis of occult retinal breaks intraoperatively, and shorter time to VH resolution.

O exercício da lectio na tradição medieval - <i>Lecturis salutem
Authors: Martines Paulo Ricardo 
Published: November 2019

O tema deste artigo se refere à prática da leitura de textos, no âmbito da universidade medieval, particularmente ao ensino cultivado por mestres e alunos segundo normas pedagógicas institucionalizadas. O exercício da leitura foi uma preocupação constante entre os mestres do período medieval, algo consignado, seja nas advertências daquelas leituras que não edificam a formação do caráter do cristão, por cultuarem tão somente a eloquência e não a virtude da sabedoria (Isidoro de Sevilha), seja pela importância dada ao saber ler e aos modos pelos quais devemos ler determinado texto (Hugo de São Vítor), a fim de formar um ‘leitor cuidadoso’ (Abelardo) e preparado para enfrentar os grandes temas da filosofia, como aqueles oferecidos nas escolas do século XII, ou na futura universidade do século XIII. Essa universidade é organizada como uma corporação de ofício e é inseparável daquilo que, na esfera da cultura da época, se denomina como ‘escolástica’, cujo ensino magistral é o elemento irradiador e foco dos estudos universitários. Veremos, neste artigo, como se consubstancia o exercício da leitura, na tradição medieval, presente no método preconizado pelos autores da ‘escolástica’ e, em particular, destacaremos o comentário de Tomás de Aquino ao tratado Sobre a Trindade, de Boécio, no tocante ao tema da classificação do saber teórico.
O FINANCIAMENTO DA EDUCAÇÃO INFANTIL A PARTIR DA IMPLEMENTAÇÃO DO FUNDEB: AVANÇOS E LIMITES
Authors: Santos Joedson Brito dos 
Published: November 2019

O presente texto objetiva discutir os possíveis avanços e limites da política de financiamento da educação infantil depois da criação do Fundo de Manutenção e Desenvolvimento da Educação Básica e de Valorização dos Profissionais da Educação (Fundeb). Trata-se de uma pesquisa qualitativa de cunho bibliográfico e documental subsidiada em autores do campo das políticas de educação infantil como Campos (1992), Campos, Rosemberg e Ferreira (2001), Didonet (2006) e Santos (2015), da área do financiamento da educação como Araújo (2006), Bassi (2011), Cara (2012; 2014), Pinto (2007), Daives (2008), Martins (2008) e Santos (2015) e em documentos legais como Brasil (1988;1996; 2006;2007; 2013). Constatou-se que apesar dos avanços do Fundeb para o financiamento desse segmento é preciso considerar que: a presença de poucos recursos novos no Fundeb considerando os recursos já previsto constitucionalmente; os baixos fatores de ponderação definidos para distribuição dos recursos para o provimento dessa etapa da educação; e, o fato dos municípios serem os entes federados com menor capacidade de arrecadação para financiar à educação, são alguns dos fatores que limitam a capacidade dessa política em assegurar a expansão do atendimento à educação infantil.
AID Phosphorylation Regulates Mismatch Repair–Dependent Class Switch Recombination and Affinity Maturation
Authors: Choi Jee Eun , Matthews Allysia J. , Michel Genesis , Vuong Bao Q. 
Published: November 2019

Abstract
Activation-induced cytidine deaminase (AID) generates U:G mismatches in Ig genes that can be converted into untemplated mutations during somatic hypermutation or DNA double-strand breaks during class switch recombination (CSR). Null mutations in UNG and MSH2 demonstrate the complementary roles of the base excision repair (BER) and mismatch repair pathways, respectively, in CSR. Phosphorylation of AID at serine 38 was previously hypothesized to regulate BER during CSR, as the AID phosphorylation mutant, AID(S38A), cannot interact with APE1, a BER protein. Consistent with these findings, we observe a complete block in CSR in AIDS38A/S38AMSH2−/− mouse B cells that correlates with an impaired mutation frequency at 5′Sμ. Similarly, somatic hypermutation is almost negligible at the JH4 intron in AIDS38A/S38AMSH2−/− mouse B cells, and, consistent with this, NP-specific affinity maturation in AIDS38A/S38AMSH2−/− mice is not significantly elevated in response to NP-CGG immunization. Surprisingly, AIDS38A/S38AUNG−/− mouse B cells also cannot complete CSR or affinity maturation despite accumulating significant mutations in 5′Sμ as well as the JH4 intron. These data identify a novel role for phosphorylation of AID at serine 38 in mismatch repair–dependent CSR and affinity maturation.

Consumer habits and preferences in the renewable energy market
Authors: Bai Attila , Balogh Péter , Pető Károly , Szakály Zoltán 
Published: November 2019

The world energy consumption was about 567-578 EJ in 2017 which is still increasing – in 2017 by 2.2%, and yearly by 1.7% on average since 2006 (BP, 2018, IEA, 2018). Within this, the consumption of residential segment plays a significant role both in the EU (42%) and in Hungary (35%) as well (Eurostat, 2019). The Hungarian population spend 12.8% (35 EUR/capita/month) of their income on energy sources, and this rate is even higher in case of the pensioners, singles and those who have lower income (KSH, 2019). At the same time, the rate of renewables in the energy mix stagnates for years worldwide (14%), it is a bit higher in the EU and in Hungary than the world average (18-18%, IEA, 2018). Thus, the renewable energy sources can also have serious perspectives in the residential cost reduction, in the sustainable energy consumption and in the local income production. Our aim is to analyse the knowledge of Hungarian consumers on renewable energy sources, their willingness to apply them and the socio-demographic factors on these. To execute the research objectives, a national representative survey with 1000 people was started in April 2019 in Hungary. Based on the results of the questionnaire, it was concluded that the information of the inhabitants is below the average in case of every examined renewable energy source, which is especially true for the biomass-based energy sources. The ease is almost as important as the environment friendliness. An excessively high rate of respondents (34 and 27%) is interested in solar panels and solar collectors, 32% of them seclude themselves from the use of these energy sources. It would be justified to extend these consumer researches in the future for more countries. The authors wish to clarify how the differences in location, income status and residential segment and values influence the spread of these energy sources in the EU and by which tools could support the usage of these in the future.

European Integrated Care Horizon 2020: increase societal participation; reduce care demands and costs in Finnish context
Authors: Heikkinen Katja , Lahti Mari , Berg Johanna , Kiseleva Arina , Eloranta Sini 
Published: November 2019

This project is part of larger European level integrated care project led by HU University of Applied Sciences.Background: In Finland, the integration of social and health care services has taken centre stage in both the policy and practice arenas. The needs of many client groups, for example mental health client, older people and families of child, are many and varied.For example, poor mental health considerably impairs well-being of the population and has considerable economic consequences like absence from work, early retirement and productive losses. Efforts to move towards integrated care in social and health care have been met with increased interest and enthusiasm in recent years. This will increase the focus to improve care and population health while containing costs. However, there is a need to better understand different integrated care approaches for social and health care and guide future implementation of new integrated care models.It is now important to move towards integrated care for many client groups e.g. mental disorders. In this, professionals with different training backgrounds co-ordinate their expertise in providing care for theirshared clients. It provides a safe nexus for the exchange of knowledge and opinions, as well as a framework for reaching a consensus about appropriate health care delivery for a particular client or client cohort. The client should have an immediate access to integrated care, with a focus on rehabilitation in patient’s social roles.Aim: Support societal participation, quality of live and reduce care demand and costs in social and health care client, for example mental health client through integration of healthcare and welfare services.
