O presente trabalho tem como finalidade oferecer informações para o médico veterinário sobre o comércio e manejo de peixes ornamentais, uma área de atuação pouco abordada pelas faculdades de Medicina Veterinária e cursos de pós-graduação. O comércio de peixes ornamentais é uma atividade bem estabelecida no Brasil. Entretanto, carece de profissionais atuando em questões como manejo profilático, patologia, diagnóstico e tratamento. Também abrange novos conceitos para o médico veterinário, como os representados pelas propriedades físicas e químicas da água, O artigo aborda, de maneira sucinta, os principais pontos dessa atividade, os quais devem ser observados sob a ótica da Medicina Veterinária.
UMA JANELA PARA O MUNDO: REFLEXÕES SOBRE AS REDES SOCIAIS EM ESPAÇOS DE APRENDIZAGEM NO ENSINO SUPERIOR
Authors: Bernardo Cavassani Thiago , De Jesus de Andrade Joana
Published: October 2019

Ao investigar a importância das novas tecnologias nas relações de ensino em nível superior a partir de interações pedagogicamente orientadas, o presente trabalho discute o impacto das redes sociais na educação. Com metodologia qualitativa, utilizou-se questionário e análise sociométrica (Gephi 0.8.2 Beta) das interações no grupo criado em uma disciplina de graduação e os dados são analisados à luz dos referenciais teóricos da área. Conclui-se que, apesar do grande potencial comunicativo, colaborativo e da ampliação do espaço-tempo acadêmico, os alunos não utilizam/entendem de forma unânime as redes sociais como recurso pedagógico formal. Talvez o momento de instabilidade e discordância expressa possa expor a difícil, mas necessária mudança das instituições educacionais.

Neste artigo apresentamos uma discussão conjunta, oriunda das inquietações de um grupo que está preocupado com questões e com processos de identificação e definição da identidade curricular dos Institutos Federais de Educação, Ciência e Tecnologia (IFs), especialmente relacionada à Educação Profissional, que considere a realidade, a sociedade e as evoluções científicas e tecnológicas. Nosso objetivo é trazer à tona, para além dos aspectos teóricos e formais na educação profissional, uma discussão que envolva o enfrentamento das questões científicas, tecnológicas e sociais por meio do currículo. Muito se fala que o currículo deve ser ativo, deve proporcionar ao estudante a possibilidade de ser um cidadão crítico e atuante, comprometido com os reflexos que a ciência e a tecnologia trazem para a sociedade. Mas o currículo realmente dá conta disso? Vivemos em uma sociedade eminentemente capitalista, na qual o consumo, a competição e o individualismo são o foco principal. Como então falar em currículo voltado para a prática social? Ou ainda vamos mais longe: de qual prática social estamos falando?

Published: October 2019

O presente artigo tem como objetivo investigar as concepções, possibilidades e desafios encontrados por professores dos Anos Iniciais do Ensino Fundamental ao desenvolverem atividades investigativas. Tais professores participaram de um processo formativo desenvolvido na Universidade Federal do ABC. Para atingir o objetivo, foi utilizada a transcrição de episódios videogravados do curso de formação, entrevistas e formulários respondidos pelos cursistas. Esses materiais são registros de avaliação do citado curso, utilizados com a devida autorização. Como referencial para o processamento e análise dos dados, foram utilizadas as contribuições para análise de dados qualitativos e foi realizada também uma análise de conteúdo do material transcrito. Foram evidenciados desafios na implementação d atividades investigativas, dentre eles estão em destaque a escassez de materiais disponíveis aos professores para implementarem este tipo de proposta, um repertório escasso de ideia dos professores, a ausência de espaço apropriado em algumas escolas e a necessidade de auxílio de outras pessoas. Os professores evidenciaram alguns desafios enfrentados, como, por exemplo, aproveitar o “erro” em atividades investigativas e problemas com a inserção das mesmas na rotina escolar. Foram encontradas também diversas potencialidades, como a possibilidade de atrelar o ensino de Ciências ao ensino de outras disciplinas por meio das atividades investigativas, possibilitar atuação mais autônoma do aluno no processo de aprendizagem e proporcionar autonomia discente para a criação de novas investigações e a metodologia. Tais elementos evidenciados devem ser estudados por mais pesquisadores em diferentes contextos para que se possa ter cada vez mais clareza deste fenômeno. Se realizadas, essas pesquisas contribuiriam com o trabalho de professores que decidam implementar atividades investigativas e de formadores que ministram cursos de formação continuada. Além disso, fundamentariam também a literatura da área e os documentos oficiais que regem a educação.

Cigarettes was one of the industrial products and international commodities that contain around 1,500 chemicals harmful to human health, but the behavior of some Indonesian teenagers had assumed that smoking is an inevitable need, a need to get along, a need to relax or share other reasons which makes smoking a normal thing. This study aimed to know the relationship between adolescent knowledge about smoking with smoking behavior in adolescents. Type of research used in this study was descriptive correlational. The number of samples used by 45 respondents. Data analysis used univariate and bivariate gang analysis using the chi-quare test. The result showed that most of the adolescents have high knowledge about smoking namely 15 people (33.3%) of respondents, with the smoking behavior of adolescents showing that the majority of adolescents amounted to 34 people (75.6%) respondents, the relationship of knowledge with adolescent smoking behavior shows that adolescents who have high knowledge with smoking behavior are 34 people (75.6%) respondents. Chi square test results show there is a relationship between knowledge and smoking behavior of adolescents, so that the value of p = 0.002 (p> 0.05). Adolescents with high knowledge experience smoking behavior more than adolescents who lack knowledge about smoking behavior. It expected that the results of this study would be one of the sources of information for the local health office and health center in overcoming disease problems arising from smoking with adolescent smoking behavior. This is valuable information for conducting or determining adolescent smoking behavioral habits.

Transmisi Wahyu: Antara Filsafat Takwil Nasr Hamid Abu Zaid dan Teori “Message Production” Ilmu Komunikasi
Authors: Hannase Mulawarman
Published: October 2019

Tulisan ini merupakan sebuah upaya untuk mengintegrasi- kan berbagai teori-teori ilmu pengetahuan modern, khususnya teori ilmu komunikasi, dengan metode penafsiran al-Qur’an yang dikem- bangkan oleh Nasr Hâmid Abû Zaid yaitu teori takwil al-Qur’an. Stu- di ini menemukan bahwa tipologi teori takwil yang dikonstruksi oleh Nasr Hâmid Abû Zaid begitu menekankan pentingnya memperhatikan peran pengarang dari teks, penafsir serta konteks, sebagai teori menaf- sirkan al-Qur’an. Setelah dibandingkan, teori ini nampak jelas sejalan dengan pandangan teori ilmu komunikasi modern yang dikembang- kan oleh Katherine Miller. Adapun pendekatan yang digunakan dalam studi ini adalah pendekatan hermeneutik dalam rangka memahami transmisi dan interpretasi teks-teks agama yang dianggap relevan de- ngan teori produksi pesan dalam ilmu komunikasi.

MEMBANGUN RELASI DI ATAS ZAWIYAH
Authors: Surasman Otong
Published: October 2019

In this modern era, even though advances in technology are increasingly advanced and communication tools are increasingly sophisticated, there is something missing that is forgotten by most humans. In fact, what is even more sad is the loss of specialties in performing prayer services, which are carried out by Muslims today. As the barometer is so very simple, the majority of Muslims today Al-Qur'an illiteracy reaches 65% more and both Muslims are still under ignorance and poverty, which shows that Muslims are not united in solving the problems of the people. Each of them prioritizes their personal and group interests, compared to resolving common interests. One very important effort to build a people, in order to achieve success in performing prayer services, is able to build the people's economy in eradicating poverty and ignorance, then start building relationships with Allah SWT above Zawiyah. This is a means of control which at the same time begs for guidance to Allah SWT, so that every problem faced by Muslims and the public is given a solution to the solution.

Making Clinical Trials More Patient-Centered Using Digital Interactive E-Consent Tools
Authors: Biesecker Barbara , Raspa Melissa , Rupert Douglas , Moultrie Rebecca , Furberg Robert , McCormack Lauren A.
Published: October 2019

Research participants are required to give their consent to participate in clinical trials and nonexempt government-funded studies. The goal is to facilitate participant understanding of the intent of the research, its voluntary nature, and the potential benefits and harms. Ideally, participants make an informed choice whether to participate; one that is based on having sufficient relevant knowledge and that is consistent with their values and preferences. Achieving this objective can be challenging, and as such, many scholars have declared the consent process flawed or “broken.” Moreover, clinical trials are complex studies, and compelling evidence suggests that current consent processes are inadequate in achieving informed choice. E-consent offers a dynamic, engaging consent delivery mode that can effectively support making informed decisions about whether to participate in a trial.
Predicting the Yield of Potential Venus Analogs from TESS and Their Potential for Atmospheric Characterization
Authors: Ostberg Colby , Kane Stephen R.
Published: October 2019

The transit method is biased toward short orbital period planets that are interior to their host star’s habitable zone. These planets are particularly interesting from the perspective of exploring runaway greenhouse scenarios and the possibility of potential Venus analogs. Here, we conduct an analysis of predicted Transiting Exoplanet Survey Satellite (TESS) planet yield estimates produced by Huang et al., as well as the TESS Object of Interest (TOI) list resulting from the observations of sectors 1–13 during Cycle 1 of the TESS primary mission. In our analysis we consider potential terrestrial planets that lie within their host star’s Venus zone. These requirements are then applied to a predicted planetary yield from the TESS primary mission and the TOI list, which results in an estimated 259 Venus analogs by the end of the TESS primary mission, and 46 Venus analogs in the TOI list for sectors 1–13. We also calculate the estimated transmission spectroscopy signal-to-noise ratio (S/N) for Venus analogs from the predicted yield and TOI list if they were to be observed by the Near-Infrared Imager and Slitless Spectrograph on the James Webb Space Telescope, as well as update the S/N cutoff values determined by Kempton et al. Our findings show that the best estimated Venus analogs and TOI Venus analogs with R

We carry out a comprehensive Bayesian correlation analysis between hot halos and direct masses of supermassive black holes (SMBHs), by retrieving the X-ray plasma properties (temperature, luminosity, density, pressure, and masses) over galactic to cluster scales for 85 diverse systems. We find new key scalings, with the tightest relation being

correlates better with the gas mass than dark matter mass. We show the important role of the environment, morphology, and relic galaxies/coronae, as well as the main departures from virialization/self-similarity via the optical/X-ray fundamental planes. We test the three major channels for SMBH growth: hot/Bondi-like models have inconsistent anticorrelation with X-ray halos and too low feeding; cosmological simulations find SMBH mergers as subdominant over most of cosmic time and too rare to induce a central-limit-theorem effect; the scalings are consistent with chaotic cold accretion, the rain of matter condensing out of the turbulent X-ray halos that sustains a long-term self-regulated feedback loop. The new correlations are major observational constraints for models of SMBH feeding/feedback in galaxies, groups, and clusters (e.g., to test cosmological hydrodynamical simulations), and enable the study of SMBHs not only through X-rays, but also via the Sunyaev–Zel’dovich effect (Compton parameter), lensing (total masses), and cosmology (gas fractions).
Investigation of 13C Isotopic Fractionation of CCH in Two Starless Cores: L1521B and L134N
Authors: Taniguchi Kotomi , Herbst Eric , Ozeki Hiroyuki , Saito Masao
Published: October 2019

We carried out observations of CCH and its two 13C isotopologues, 13CCH and C13CH, in the 84–88 GHz band toward two starless cores, L1521B and L134N (L183), using the Nobeyama 45 m radio telescope. We detected C13CH with a signal-to-noise ratio of 4, whereas no line of 13CCH was detected in either of the dark clouds. The column densities of the normal species were derived to be (1.66 ± 0.18) × 1014 cm−2 and (7.3 ± 0.9) × 1013 cm−2 (1σ) in L1521B and L134N, respectively. The column density ratios of N(C13CH)/N(13CCH) were calculated to be >1.1 and >1.4 in L1521B and L134N, respectively. The characteristic that 13CCH is less abundant than C13CH is likely common for dark clouds. Moreover, we find that the 12C/13C ratios of CCH are much higher than those of HC3N in L1521B by more than a factor of 2, as well as in Taurus Molecular Cloud-1 (TMC-1). In L134N, the differences in the 12C/13C ratios between CCH and HC3N seem to be smaller than those in L1521B and TMC-1. We discuss the origins of the 13C isotopic fractionation of CCH and investigate possible routes that cause the significantly high 12C/13C ratio of CCH especially in young dark clouds, with the help of chemical simulations. The high 12C/13C ratios of CCH seem to be caused by reactions between hydrocarbons (e.g., CCH, C2H2, l-C3H and c-C3H) and C+.

Compact symmetric objects (CSOs) have been observed with Chandra and XMM-Newton to gain insights into the initial stages of a radio source evolution and to probe the black hole activity at the time of relativistic outflow formation. However, there have been no CSO observations to date at the hard X-ray energies (>10 keV), impeding our ability to robustly constrain the properties of the intrinsic X-ray emission and of the medium surrounding the young expanding jets. We present the first hard X-ray observation of a CSO performed with the Nuclear Spectroscopic Telescope Array (NuSTAR). Our target, OQ +208, is detected up to 30 keV, and thus we establish CSOs as a new class of the NuSTAR sources. We analyze the NuSTAR data jointly with our new Chandra and archival XMM-Newton data and find that a young (∼250 yr old) radio jet spanning the length of 10 pc coexists with cold obscuring matter, consistent with a dusty torus, with an equivalent hydrogen column density of N
H = 1023–1024 cm−2. The primary X-ray emission is characterized by a photon index of Γ ∼ 1.45 and an intrinsic 0.5–30 keV luminosity of L ≃ 1043 erg s−1. The results of our spectral modeling and broad-line optical classification of the source suggest a porous structure of the obscuring torus. Alternatively, the source may belong to the class of optically unobscured/X-ray-obscured active galactic nucleus. The observed X-ray emission is too weak compared to that predicted by the expanding radio lobes model, leaving an accretion disk corona or jets as the possible origins of the X-ray emission from this young radio galaxy.

We analyze the light curve of the M5.5 dwarf Proxima Centauri obtained by the Transiting Exoplanet Survey Satellite (TESS) in Sectors 11 and 12. In the ≈50 day long light curve we identified and analyzed 72 flare events. The flare rate was 1.49 events per day; in total, 7.2% of the observing time was classified as flaring. The estimated flare energies were on the order of 1030–1032 erg in the TESS passband (≈4.8× higher in bolometric energies, but on the same order of magnitude). Most of the eruptions appeared in groups. Two events showed quasiperiodic oscillations during their decay phase with a timescale of a few hours, which could be caused by quasiperiodic motions of the emitting plasma or oscillatory reconnection. From the cumulative flare frequency distribution we estimate that superflares with energy output of 1033 erg are expected to occur three times per year, while magnitude larger events (with 1034 erg) can occur every second year. This reduces the chances of habitability of Proxima Cen b, although earlier numerical models did not rule out the existence of liquid water on the planetary surface. We did not find any obvious signs of planetary transit in the light curve.

We present calculated cross sections and rate coefficients for the formation of the dicarbon cation (

Résumé Dans cet article, nous nous attachons à étudier avec précision, l’impact de l’arrivée d’informations publiques sur le processus générateur de prix des actifs financier, et plus particulièrement dans quelle mesure les changements dans le processus d’arrivée de l’information destinée aux investisseurs sont à l’origine des sauts de variances généralement observés. À l’aide d’un échantillon composé de l’ensemble des titres inclus dans l’indice CAC 40 sur la période du 01/01/1999 au 31/12/2003 et de la totalité des annonces Reuters spécifiques à ceuxci, nous répliquons dans un premier temps les travaux de Kalev, Liu, Pham et Jarnecic (2004) et démontrons que le flux d’informations publiques explique une grande partie de la persistance de la volatilité conditionnelle mise en évidence par les processus GARCH. Dans un second temps, nous introduisons les processus à changement de régime markovien afin de déterminer la probabilité qu’a le processus générateur des rentabilités de se trouver dans un régime à haute volatilité. Leur utilisation démontre alors l’impact positif et significatif, pour une grande majorité des titres étudiés, du nombre d’annonces quotidiennes sur la probabilité de se trouver dans un régime à haute volatilité. L’analyse en panel confirme ces résultats tout en contrôlant l’impact de la variance conditionnelle du portefeuille de marché et celui de l’indice sectoriel dont les titres font partie. De tels résultats confortent l’hypothèse de mélange de distributions de Clark (1973), et plus particulièrement l’intuition de Roll (1984) affirmant que le processus des rentabilités est un mélange de distributions guidé par la fréquence de l’arrivée d’informations. En divisant notre échantillon par catégorie de sujet d’annonces ou par la période durant laquelle elles sont publiées, nous mettons également en évidence le fait que les informations tombées durant les heures de cotation ont un impact plus important que celles publiées durant les heures de non cotation. Concernant le contenu de ces annonces, celles traitant des politiques gouvernementales ou de régulations sont celles ayant le plus d’impact sur la volatilité conditionnelle des titres, viennent ensuite les prévisions de résultats, et plus particulièrement les recommandations et commentaires d’analystes. Et enfin les annonces concernant les fusions et acquisitions qui paraissent bien, elles aussi, affecter significativement la volatilité des actions. Enfin, nous examinons également les effets asymétriques mis en évidence dans la littérature. Les résultats sont globalement identiques aux précédents travaux et les annonces négatives semblent, en moyenne, se situer de manière plus probable que les positives, dans le régime à forte volatilité. Néanmoins, une fois pris en compte le contenu informationnel moyen de l’ensemble des annonces publiées, cette asymétrie disparaît.
Le rôle de la garantie des dépôts dans la prévention des paniques bancaires : fondements théoriques et études empiriques
Authors: Madiès Philippe
Published: October 2019

Résumé Cet article se propose tout d’abord de tirer les enseignements de la littérature théorique sur les ruées bancaires et sur les moyens de prévenir de tels phénomènes. La garantie des dépôts sera comparée à un certain nombre de solutions alternatives telles qu’elles ont pu être, pour certaines, observées dans le passé : la suspension partielle ou totale de la convertibilité des dépôts (dans le cadre ou non d’une association de banques, clearinghouse association ) et le «  narrow banking  ». Il en ressort que deux conceptions des ruées bancaires s’opposent. Tout d’abord, les ruées bancaires peuvent être purement auto-réalisatrices et résultent d’un défaut de coordination entre déposants. Elles sont inefficientes au sens où elles peuvent conduire à la faillite de banques saines et nécessitent pour être évitées la mise en place d’une assurance des dépôts fortement protectrice. Ensuite, la théorie des « ruées informées » montre que les déposants, informés des difficultés à venir de leur banque (informations sur les fondamentaux), se précipitent de manière préventive pour retirer leur fonds. Les prescriptions réglementaires sont alors différentes. Pour tester les théories en concurrence, les travaux empiriques ont pris la forme tout d’abord d’études historiques menées sur les paniques bancaires passées, notamment aux États-Unis. La théorie des « ruées informées » en ressort renforcée, même si les résultats demeurent controversés. Cependant, des études expérimentales menées sur les paniques bancaires auto-réalisatrices montrent que ces ruées sont des phénomènes récurrents et persistants. Pour prévenir de telles paniques, l’assurance des dépôts doit en outre proposer aux déposants une couverture totale même si une protection élevée incite les déposants à moins de vigilance et conduit donc à une prise de risque accrue des banques (aléa de moralité). En revanche, une couverture partielle des déposants constitue un moyen suffisant d’empêcher des « ruées informées ». Enfin, les études empiriques menées sur les crises bancaires récentes montrent que l’assurance des dépôts obligatoire et fortement protectrice peut être source d’instabilité sauf si elle se situe dans un environnement institutionnel de qualité où la supervision bancaire et la réglementation bancaire s’exercent efficacement. L’efficacité de la garantie des dépôts ne peut donc s’évaluer indépendamment du cadre réglementaire dans lequel celle-ci s’insère.
La prime de risque dans un cadre international : le risque de change est-il apprécié ?
Authors: Arouri Mohamed El Hédi
Published: October 2019

Résumé L’objet de cet article est d’étudier les déterminants et la dynamique de la prime de risque des actions dans un cadre international. Pour ce faire, nous utilisons un modèle GARCH multivarié et testons une version conditionnelle du MEDAF international avec déviations de la PPA. Le modèle est estimé sous l’hypothèse d’intégration financière parfaite puis sous l’hypothèse de segmentation partielle conjointement pour cinq marchés : deux marchés développés, deux marchés émergents et le marché mondial. Nos résultats soutiennent le MEDAFI et indiquent que le risque des taux de change est rémunéré internationalement. Cependant, nous trouvons que la prime de change varie considérablement dans le temps et d’un marché à l’autre.
Stock Prices, Inflation and Stock Returns Predictability
Authors: Boucher Christophe
Published: October 2019

Résumé Dans cet article, nous considérons la relation entre les cours boursiers et l’inflation aux États-Unis dans une nouvelle perspective. Nous estimons la tendance stochastique commune entre les cours boursiers réels, tels que reflétés par l’ Earning Price Ratio (EPR), et l’inflation anticipée et réalisée. Nous étudions en particulier le rôle des déviations transitoires de la tendance de long terme commune entre l’EPR et l’inflation réalisée pour prévoir les fluctuations du marché boursier. Nos résultats montrent que ces déviations temporaires possèdent un pouvoir prédictif hors-échantillon sur les rendements réels des actions. Nos résultats indiquent également que l’information sur les rendements réels futurs contenue dans ces déviations n’apparaît pas, à des horizons courts et intermédiaires, dans les variables identifiées jusqu’ici par la littérature pour prévoir les rendements boursiers.
Dynamique non-linéaire des marchés boursiers du G7 : une application des modèles STAR
Authors: Jawadi Fredj , Koubbaa Yosra
Published: October 2019

Résumé Un des débats d’actualité se focalise autour de l’étude de la structure de dépendance des prix des actifs financiers. La recherche d’une spécification de cette dépendance et d’une représentation de la dynamique sous-jacente a fait l’objet de plusieurs études empiriques. Ces travaux se sont essentiellement centrés sur la définition de la forme fonctionnelle du processus sous-jacent à la dynamique des prix. L’idée consiste à adapter la théorie des oscillations non-linéaires aux phénomènes économiques puisque ce type de modélisation coïncide avec l’évolution des séries et financières. La réflexion a été pour l’essentiel conduite dans le cadre temporel et peu d’études ont porté sur la spécification de la non-linéarité à travers les tests d’efficience du marché financier, la prise en compte de l’hétérogénéité des agents et de l’asymétrie due à la présence de coûts de transaction et d’information. La réponse n’est pas évidente en soi car les approches linéarité-non linéarité, efficience-inefficience, dépendance-indépendance sont alternatives mais exclusives. Néanmoins, ce travail a pour ambition de présenter un point de vue personnel sur la problématique sous-jacente aux dynamiques des marchés boursiers. Plus spécifiquement, la volonté de trouver un sens économique au rejet de la linéarité nous a conduit à tester l’hypothèse d’indépendance contre l’alternative de dépendance non-linéaire. À cette fin, nous proposons de modéliser les séries boursières au moyen des modèles à changement de régime de type STAR (Smooth Transition Autoregressive Models) afin de reproduire la non-linéarité présente en moyenne tout en utilisant des outils statistiques et des tests économétriques récents en vue d’examiner la dynamique des cours boursiers à court terme.
L'impact de l'admission à la cote sur les performances économiques des entreprises
Authors: Serve Stéphanie
Published: October 2019

Résumé Cet article étudie l’évolution des performances économiques de 115 entreprises introduites en bourse au Nouveau Marché français sur la période 1996-2000. Les résultats mettent en évidence un déclin significatif des performances économiques sur la période post-introduction. Il va de pair avec une croissance soutenue du chiffre d’affaires mais une réduction des dépenses d’investissement. Par ailleurs, les entreprises où le taux de rétention de l’actionnariat dirigeant est le plus élevé enregistrent le plus fort déclin de performance.
