Relationships Among Animal Communities, Lentic Habitats, and Channel Characteristics for Ecological Sediment Management
Authors: Choi Mikyoung , Takemon Yasuhiro , Ikeda Kinko , Jung Kwansue
Published: October 2018

This study used a multiscale analysis of relationships among the bitterling and mussel communities, lentic habitat structures with conditions and flooding frequency, and channel characteristics for application in ecological sediment management. From the Kizu River in Japan, 120 lentic habitats were sampled in 2007 and 2010. The floodplain vertical shape index (FVSI), which indicates the degree of convexity or concavity of the vertical shape of a floodplain, was used as channel characteristics using historical cross-section profiles obtained from 1960 to 2012. For examining the relationships between bitterlings/mussels and each habitat condition or structure, abundance values of bitterlings and mussels were transformed into habitat suitability index (HSI). Furthermore, the relationships between the number of habitat structures and FVSI were analyzed. The results indicated that bitterlings and mussels are more abundant in terrace ponds than in active ponds, especially so in terrace ponds located in the lower area of bars with a flooding frequency of 8–16 days/year (bitterlings), those located in the lower area of bars with a flooding frequency of 8 days/year, and those located in the upper area of bars with a flooding frequency of 16–22 days/year (mussels). These ponds tended to have less than 1 cm mud depth that was negatively related to abundance of mussels. These suitable habitat types tended to be located in channels with a floodplain vertical shape index between −0.35 and 0.05. We established countermeasures to prevent channel types with floodplain vertical shape index exceeding 0.05 instead of restoring the previous channel conditions.

Published: October 2018

The aim of the study was to demonstrate the diagnostic and prognostic value of SPECT/CT in sentinel lymph node mapping (SLNM) in patients with invasive breast cancer. Methods: 114 patients with invasive breast cancer with clinically negative lymph nodes were included in this retrospective study as they were referred for SLNM with 99mTc-nanocolloid. Planar image acquisition was accomplished in a one-day or two-day protocol depending on the schedule of the surgical procedure. Low dose SPECT/CT was performed after the planar images. The sentinel lymph node biopsy (SLNB) was considered false negative if a primary recurrence developed within 12 months after SLNB in the axilla from which a tumor-free SLN had been removed. Results: Between December 2009 and December 2011, 114 patients (pts.) underwent SLNM with additional SPECT/CT. Planar imaging identified in 109 pts. 139 SLNs, which were tumor-positive in 42 nodes (n = 41 pts.). SPECT/CT identified in 81 pts. 151 additional SLNs, of which 19 were tumor-positive and led to therapy change (axillary lymph node dissection) in 11 pts. (9.6 %). Of overall 61 tumor-positive SLNs (n = 52 pts.) SPECT/CT detected all, whereas planar imaging detected only 42 of 61 (P < 0.0001). No patient had lymph node metastasis within 12 months after SLNB in the axilla from which a tumor-free SLN had been removed resulting in a false-negative rate of 0 %. The local relapse rate was 1.8 % leading to a 4-year disease-free survival rate of 90 %. Conclusion: Among patients with breast cancer, the use of SPECT/CT-aided SLNM correlated due to a better anatomical localization and identification of planar not visible SLNs with a higher detection rate of SLNs. This led to therapeutic consequences and an excellent false-negative and 4-year disease-free survival rate.

Published: October 2018

In this article, we have successfully designed and demonstrated a novel continuous process for assembling targeting ligands, peptidic spacers, fluorescent tags and a chelating core for the attachment of cytotoxic molecules, radiotracers, nanomaterials in a standard Fmoc solid-phase peptide synthesis in high yield and purity. The differentially protected Fmoc-Lys-(Tfa)-OH plays a vital role in attaching fluorescent tags while growing the peptide chain in an uninterrupted manner. The methodology is versatile for solid-phase resins that are sensitive to mild and strong acidic conditions when acid-sensitive side chain amino protecting groups such as Trt (chlorotrityl), Mtt (4-methyltrityl), Mmt (4-methoxytrityl) are employed to synthesise the ligand targeted fluorescent tagged bioconjugates. Using this methodology, DUPA rhodamine B conjugate (DUPA = 2-[3-(1,3-dicarboxypropyl)ureido]pentanedioic acid), targeting prostate specific membrane antigen (PSMA) expressed on prostate, breast, bladder and brain cancers and pteroate rhodamine B, targeting folate receptor positive cancers such as ovarian, lung, endometrium as well as inflammatory diseases have been synthesized. In vitro studies using LNCaP (PSMA +ve), PC-3 (PSMA −ve, FR −ve) and CHO-β (FR +ve) cell lines and their respective competition experiments demonstrate the specificity of the newly synthesized bioconstructs for future application in fluorescent guided intra-operative imaging.
THE DYNAMIC EFFECTS OF ONLINE PRODUCT REVIEWS ON PURCHASE DECISIONS
Authors: Chen Jia , Kou Gang , Peng Yi
Published: October 2018

Previous studies have demonstrated that online reviews play an important role in the purchase decision process. Though the effects of positive and negative reviews to consumers’ purchase decisions have been analyzed, they were examined statically and separately. In reality, online review community allows everyone to express and receive opinions and individuals can reexamine their opinions after receiving messages from others. The goal of this paper is to study how potential customers form their opinions dynamically under the effects of both positive and negative reviews using a numerical simulation. The results show that consumers with different membership levels have different information sensitivities to online reviews. Consumers at low and medium membership levels are often persuaded by online reviews, regardless of their initial opinion about a product. On the other hand, online reviews have less effect on consumers at higher membership levels, who often make purchase decisions based on their initial impressions of a product.
Analytical Model for the Dynamical Motion of the Bulges of Two Interacting Galaxies
Authors: López Elkin L. , López Gustavo V. , Kemp Simon N.
Published: October 2018

Two mathematical models of three bodies of variable masses are used to obtain a qualitative description of two interacting galaxies with mass exchange and mass loss. The reference system is centered on the largest body (the most massive galaxy), and the other two bodies are allowed to move around this one under the laws of gravity. The third body, which simulated the mass lost by the second galaxy in the form of a tail, increases its mass due to the mass lost by the second body and follows its trajectory. We are interested in knowing the time evolution of the separation of the two bulges of the interacting galaxies, and the parameters for the analytical models are obtained by running simulations with the GADGET-2 N-body code. The resulting behavior of this distance in our mathematical models is qualitatively in good agreement with that obtained by this code.

We present the results of a deep high-contrast imaging search for planets around Vega. Vega is an ideal target for high-contrast imaging because it is bright, nearby, and young with a face-on two-belt debris disk that may be shaped by unseen planets. We obtained J- and H-band data on Vega with the coronagraphic integral-field spectrograph Project 1640 (P1640) at Palomar Observatory. Two nights of data were obtained in 2016, in poor seeing conditions, and two additional nights in more favorable conditions in 2017. In total, we obtained 5.5 hours of integration time on Vega in moderate to good seeing conditions (<1.″5). We did not detect any low-mass companions in this system. Our data present the most sensitive contrast limits around Vega at very small separations (2–15 au) thus far, allowing us to place new constraints on the companions that may be sculpting the Vega system. In addition to new constraints, as the deepest data obtained with P1640, these observations form the final legacy of the now decommissioned instrument.
Disentangling Blended K2 Photometry: Determining the Planetary Host Star
Authors: Payne Alan N. , Ciardi David R. , Kane Stephen R. , Carter Brad
Published: October 2018

The presence of companion stars, whether bound or unbound, make correct identification of the planetary hosting star difficult when a planet has been detected through a photometrically blended transiting event. We present an approach that uses a combination of light curve analysis and stellar modeling to disentangle eight K2 photometrically blended binary systems that have either a confirmed or suspected planet to identify the probable host star. The key to our approach is the use of the mean stellar density, calculated using the transit geometry, as a discriminator. The approach is strongly dependent on the difference in magnitude between the stars and the observed transit depth, which is corrected by the flux ratio between the two stars. While our approach does not lead to a definitive result for all systems, we were able to determine the following for the eight systems in this case study: there are two systems where the primary was highly likely to be the planet-hosting star (>90% likelihood); three systems where the primary was likely to be the hosting star (>55% likelihood); one system where the secondary was likely to be the planet-hosting star (>55% likelihood); and two systems where we were uncertain which star was the planet-hosting star (≈50% likelihood to be either the primary or the secondary). Two systems, denoted by their EPIC number, EPIC 201546283 and EPIC 201862715, had confirmed planets, K2-27b and K2-94b, respectively, with radii of 4.0 ± 0.1 and 16.4 ± 2.9 R⊕, respectively.
Hints of Multiple Populations in Intermediate-age Clusters of the Small Magellanic Cloud
Authors: Piatti Andrés E.
Published: October 2018

We report on the magnitude of the intrinsic [Fe/H] spread in the Small Magellanic Cloud (SMC) intermediate-age massive clusters NGC 339, 361, Lindsay 1 and 113, respectively. In order to measure the cluster metallicity dispersions, we used accurate Strömgren photometry of carefully selected cluster red giant branch (RGB) stars. We determined the Fe-abundance spreads by employing a maximum likelihood approach. The spreads obtained using the more accurate photometry of the brighter RGB stars resulted to be marginal (∼0.05 ± 0.03 dex) for NGC 339 and NGC 361, while for Lindsay 1 and Lindsay 113, we obtained metallicity spreads of 0.00 ± 0.04 dex. From these results, we speculate that NGC 361 is added to the group of four SMC clusters with observational evidence of multiple populations (MPs). Furthermore, in the context of the present debate about the existence of Fe-abundance inhomogeneities among old clusters with MPs, these outcomes place new constrains on recent theoretical speculations for making this phenomenon visible.
The First Orbital Period of a Very Bright and Fast Nova in M31: M31N 2013-01b
Authors: Marelli Martino , De Martino Domitilla , Mereghetti Sandro , De Luca Andrea , Salvaterra Ruben , Sidoli Lara , Israel Gianluca , Rodriguez Guillermo
Published: October 2018

We present the first X-ray and UV/optical observations of a very bright and fast nova in the disk of M31, M31N 2013-01b. The nova reached a peak magnitude R ∼ 15 mag and decayed by 2 mag in only 3 days, making it one of the brightest and fastest novae ever detected in Andromeda. From archival multiband data we have been able to trace its fast evolution down to U > 21 mag in less than two weeks and to uncover for the first time the super-soft X-ray phase, whose onset occurred 10–30 days from the optical maximum. The X-ray spectrum is consistent with a blackbody with a temperature of ∼50 eV and emitting radius of ∼4 × 109 cm, larger than a white dwarf (WD) radius, indicating an expanded region. Its peak X-ray luminosity, 3.5 × 1037 erg s−1, places M31N 2013-01b among the most luminous novae in M31. We also unambiguously detect a short 1.28 ± 0.02 hr X-ray periodicity that we ascribe to the binary orbital period, possibly due to partial eclipses. This makes M31N 2013-01b the first nova in M31 with an orbital period determined. The short period also makes this nova one of the few known below the 2–3 hr orbital period gap. All of the observed characteristics strongly indicate that M31N 2013-01b harbors a massive WD and a very low mass companion, consistent with being a nova belonging to the disk population of the Andromeda galaxy.
Coronal Properties of Swift/BAT-selected Seyfert 1 AGNs Observed with NuSTAR

Published: October 2018

The NuSTAR observatory, with its high sensitivity in hard X-rays, has enabled detailed broadband modeling of the X-ray spectra of active galactic nuclei (AGNs), thereby allowing constraints to be placed on the high-energy cutoff of the X-ray coronal continuum. We investigate the spectral properties of a sample of 46 NuSTAR-observed Seyfert 1 AGNs selected from the Swift/Burst Alert Telescope 70 month hard X-ray survey. Our measurements of the high-energy cutoff of the continuum from modeling the NuSTAR X-ray spectra are used to map out the temperature–compactness (θ–l) plane for AGN coronae. We find that most of the coronae lie clustered near the boundary for runaway pair production, suggesting that annihilation and pair production act to regulate the temperature of the corona. We discuss the implications of coronae whose high-energy cutoff may indicate a low coronal temperature on the heating and thermalization mechanisms in the corona.
The Changing-look Quasar Mrk 590 Is Awakening

Mrk 590 was originally classified as a Seyfert 1 galaxy, but then it underwent dramatic changes: the nuclear luminosity dropped by over two orders of magnitude and the broad emission lines all but disappeared from the optical spectrum. Here we present follow-up observations to the original discovery and characterization of this “changing-look” active galactic nucleus (AGN). The new Chandra  and Hubble Space Telescope observations from 2014 show that Mrk 590 is awakening, changing its appearance again. While the source continues to be in a low state, its soft excess has re-emerged, though not to the previous level. The UV continuum is brighter by more than a factor of two and the broad Mg ii emission line is present, indicating that the ionizing continuum is also brightening. These observations suggest that the soft excess is not due to reprocessed hard X-ray emission. Instead, it is connected to the UV continuum through warm Comptonization. Variability of the Fe Kα emission lines suggests that the reprocessing region is within ∼10 lt-yr or 3 pc of the central source. The change in AGN type is neither due to obscuration nor due to one-way evolution from Type 1 to Type 2, as suggested in the literature, but may be related to episodic accretion events.
Percepções de estudantes de um curso de licenciatura em física sobre a leitura e a escrita no ensino e na aprendizagem de física
Authors: Setlik Joselaine , Higa Ivanilda
Published: October 2018

Este trabalho problematiza percepções de licenciandos em Física sobre a leitura e escrita de textos no ensino e na aprendizagem de física. Estudos têm indicado dificuldades que professores enfrentam ao utilizar esses processos, que podem estar ligadas com a não usualidade dessas práticas na própria formação inicial desses profissionais. São analisadas respostas de oito estudantes a um questionário organizado em três partes: a primeira visa conhecer o perfil do estudante, a segunda suas concepções sobre o uso e importância da leitura e da escrita na sua aprendizagem de conceitos físicos e formação profissional, e a terceira, suas percepções sobre essas práticas no Ensino Médio (colocando-se como futuro professor). As reflexões são construídas tendo em vista a teoria de Vigotski sobre leitura e escrita, assumindo-as como práticas socioculturais. Os resultados indicam que para estes futuros professores a leitura é considerada importante para a aprendizagem, principalmente pela compreensão conceitual que ela proporciona. A escrita de textos é vista como mais um recurso e, principalmente no Ensino Superior, associada à memorização de informações. O trabalho alerta para a necessidade de ampliar o olhar desses futuros professores sobre a leitura e a escrita através de discussões da temática durante sua formação inicial, além de incentivar o seu uso na aprendizagem de física, como alunos que são da Licenciatura.
A prática da leitura no ensino de química: modos e finalidades de seu uso em sala de aula
Authors: Scherer Wenzel Judite , Martins Joana Laura de Castro , Colpo Camila Carolina , Dos Anjos Ribeiro Thiago
Published: October 2018

O presente artigo contempla um estudo sobre a prática da leitura no Ensino de Química. Parte-se do pressuposto de que a prática da leitura em aulas de Química possibilita ao estudante um maior contato com a linguagem específica dessa ciência e com isso qualifica a sua aprendizagem. Com o objetivo de visualizar como tal prática tem sido conduzida nas aulas de Química e de compreender as finalidades do seu uso, realizou-se uma revisão bibliográfica nos Anais do Encontro Nacional de Ensino de Química e nos anais do Encontro Nacional de Pesquisa em Educação em Ciências. Também foi realizado um olhar para os últimos anos de publicações da Revista Química Nova na Escola. Os dados foram analisados com base na análise textual discursiva e emergiram três categorias: gêneros discursivos, interações discursivas e estratégias de leitura. Os resultados construídos reforçaram a importância da prática da leitura no processo de aprender Química apontando-a como modo de oportunizar a apropriação e a significação conceitual em química e a formação de um estudante mais crítico e participativo.
Abordagem para Seleção de Variáveis Preditivas no Contexto de Controle de Inventários
Authors: Burgel Evandro , Anzanello Michel José
Published: October 2018

A obsolescência de estoques é um fenômeno de destaque nas organizações, demandando o uso de métodos que identifiquem o inventário excessivo antes dele tornar-se obsoleto. Este artigo propõe um método para selecionar variáveis independentes em modelos de regressão preditivos com vistas à projeção do inventário ao longo do tempo, com o objetivo de reduzir o risco de obsolescência futuro. A abordagem proposta possui cinco passos, sendo os quatro primeiros dedicados à identificação dos fatores que contribuem para a obsolescência do inventário, a classificação do estoque em categorias e faixas de idade, a seleção de variáveis em contexto de PLS, a modelagem de regressão para projeção da idade do inventário ao longo do tempo e a definição de diretrizes para redução do risco de obsolescência. O quinto passo do método utiliza o conceito do ciclo PDCA buscando a melhoria contínua do processo e dos resultados. Na aplicação em uma indústria de bens de consumo, o método previu com precisão superior a 95% o montante do inventário por faixa de idade em um horizonte de seis meses.

Mediante técnicas bibliométricas analisaram-se as variáveis associadas ao uso da literatura quanto ao tipo de documento citado, periódicos mais utilizados, procedência geográfica e institucional dos autores e da bibliografia utilizada, além da análise das citações e das redes de relações estabelecidas mundialmente, referentes às pesquisas sobre cianobactérias, cianotoxinas e o tratamento de água, em escala mundial. Analisaram-se os dados bibliométricos de 1255 trabalhos publicados entre 1980 e junho de 2017. Pesquisadores pertencentes à Chinese Academy of Sciences lideram o número de publicações, seguidos do Australian Water Quality Center e da Universidade do Porto. Em relação ao país de origem dos autores, a China apresenta a maior frequência de ocorrência, seguida dos Estados Unidos, Austrália, Alemanha, Reino Unido, Polônia e Brasil (em sétimo lugar). Os três periódicos de maior destaque foram o Toxicon, Water Research, Environmental Science and Technology. O ano de 2013 apresentou o maior número de publicações desde 1980.
A temática CTS na educação tecnológica
Authors: Ferri Juliana , Freitas Carlos Cesar Garcia , Rosa Selma Dos Santos
Published: October 2018

Este trabalho teve o objetivo de analisar a inserção da temática Ciência, Tecnologia e Sociedade (CTS) nos cursos de graduação, em uma Universidade Pública Federal no Estado do Paraná - Brasil. Para cumprir com este objetivo efetuamos uma pesquisa descritiva, de caráter quantitativa, mediante análise documental dos cursos, sob a perspectiva do material disponível no website da Instituição. Por conseguinte, complementamos a pesquisa com um levantamento de campo junto aos docentes por meio da aplicação de um questionário eletrônico. O que foi constatado, na instituição, é que institucionalmente a temática CTS não é considerada como algo relevante dentro da educação tecnológica, em nível de graduação, sendo um assunto optativo entre um rol de alternativas dispostas aos alunos. Apesar da maioria dos docentes conhecerem o assunto e terem ciência da importância da temática, este fato não provocou uma mudança efetiva nas propostas dos cursos.
Des faillis dans l’ombre de la « Belle Époque ». Faire face à l’échec, faire face à la honte. Belgique, 1896-1914
Authors: Debruyne Emmanuel
Published: October 2018

Quelle est la part de la honte dans le vécu d’un failli ? En confrontant la procédure de mise en faillite aux trajectoires de vie de 21 individus qui y ont été soumis dans la région de Namur au tournant des XIX e et XX e  siècles, cet article explore la charge de la honte dans de telles situations et comment elle a pu influencer leur devenir et les choix qu’ils ont posés pour se reconstruire. Si l’expression de la honte apparaît rarement de manière explicite dans les pièces de procédure, le déroulement de celle-ci et les trajectoires individuelles n’en laissent pas moins cerner sa présence. Face à la procédure, les faillis s’avèrent notamment réticents à consentir à faire aveu de leur faillite, alors même que celui-ci est prescrit par la loi. Une minorité va plus loin en anticipant par la fuite la découverte de leur état. Une fois la procédure enclenchée, la révélation de la faillite par voie de presse, les confrontations avec les créanciers ou encore la vente publique ne font qu’accentuer l’humiliation. Et au lendemain de celle-ci, rares sont les faillis qui demeurent dans la localité où ils ont fait faillite. La honte affecte leur mobilité résidentielle en les dirigeant vers la grande ville, qui leur offre le soulagement de l’anonymat et la possibilité de se reconstruire socialement et économiquement. Son rôle n’est pas fini pour autant, tant elle peut peser jusqu’à l’éclatement sur le noyau familial, mais aussi pousser le failli et ses proches à la combattre et à rétablir leur honneur.
L’usure de la décentralisation, un handicap pour la France de demain ?
Authors: Olivérès Christian
Published: October 2018

La décentralisation devait apporter une vraie amélioration dans l’administration de nos territoires. Rapprocher la décision des citoyens, renforcer la démocratie, permettre une proximité d’action, favoriser l’investissement, tels étaient ses objectifs. Après vingt ans de développement et de croissance, parfois débridée, les collectivités locales n’ont pas su dépasser de façon active et adaptée leurs limites administratives pour promouvoir des formes d’association répondant aux besoins de leurs populations. Elles se sont enfermées dans des territoires exigus et parfois devenus incohérents car les modes de vie et les attentes de nos concitoyens ont fortement changé. Elles ont été fortement affectées par les difficultés financières qu’elles ont peu anticipées. Une caste de responsables politiques et techniques s’est imposée à leur tête sans que pour autant la démocratie locale connaisse une nouvelle dynamique. À l’heure d’une recomposition du fonctionnement territorial de l’espace national, il faut trouver d’autres modalités de choix et d’arbitrage. L’usure oblige à refonder.

La Télé-fibrinolyse est reconnue comme outil incontournable pour permettre à tout citoyen de bénéficier du 1 er traitement curatif que représente la fibrinolyse dans les premières heures d’un infarctus cérébral. Utilisée à grande échelle en Bourgogne avec 21 Hôpitaux Généraux en lien avec le CHU de Dijon, une évaluation médicale et économique s’est imposée. Méthodes : Nous exposons nos travaux menés sous la coordination du Registre Dijonnais des AVC qui évalue depuis plus de 30 ans les pratiques de soins et les innovations thérapeutiques dédiées à l’Accident Vasculaire Cérébral (AVC). Résultats : Il a été démontré en Bourgogne que la Télé-fibrinolyse est aussi efficace et sécurisée que la fibrinolyse effectuée par le site expert. Sur le plan médico-économique, notre travail a montré 2 résultats : un coût de prise en charge légèrement supérieur pour les actes de fibrinolyse effectués à distance comparés à la fibrinolyse effectuée dans le site expert, expliqué par le coût des transports. un coût moyen par patient significativement plus élevé que les recettes uniquement pour la fibrinolyse effectuée dans le site expert. En conclusion : La Télé-fibrinolyse est un acte efficace et sécurisée qui va devoir s’adapter avec les prochaines recommandations sur la sélection des malades pouvant bénéficier du 2 e traitement efficace que représente la Thrombectomie Mécanique qui, pour l’instant, ne s’effectue que dans des sites experts.
« Moi je whitise jamais. » Accent, subjectivité et processus d’accommodation langagière en contexte migratoire et postcolonial
Authors: Telep Suzie
Published: October 2018

Cet article a pour but d’analyser le rôle de la subjectivité dans les processus d’accommodation phonétique des sujets parlants en contexte migratoire et postcolonial, à partir de l’étude du cas d’un jeune adulte migrant d’origine camerounaise, militant dans une association panafricaine à Paris. La subjectivité, processus de construction du sujet, est toujours marquée par le « paradoxe de l’assujettissement » (Butler 2002), soit une tension entre assujettissement et émancipation. À partir de l’analyse de la variabilité phonostylistique dans des interactions publiques à visée politique, il s’agit de montrer dans quelle mesure l’accent fonctionne comme un lieu du désir central dans la subjectivation du sujet racisé, et manifeste une tension entre son désir d’identification à l’autre et son désir de singularisation, résultant en partie des rapports de pouvoir postcoloniaux qui contraignent sa puissance d’agir.

Taming Tax Competition with a European Corporate Income Tax
Authors: Candau Fabien , Le Cacheux Jacques
Published: October 2018

Cet article propose une revue de la littérature originale sur la concurrence fiscale et apporte de nouvelles preuves empiriques concernant l’intensité des interactions stratégiques entre gouvernements européens, la concurrence fiscale est ainsi trois fois plus forte pour les actifs financiers que pour d’autres capitaux moins mobiles. Nous présentons également plusieurs stratégies d’optimisation fiscale d’entreprises multinationales et documentons quelques études de cas d’évasion fiscale. Les montants optimisés par ces entreprises sont comparables aux contributions annuelles versées au budget de l’UE par des pays comme le Royaume-Uni, l’Irlande, les Pays-Bas ou le Luxembourg. Nous estimons que les pertes totales de recettes pour les gouvernements de l’UE dues à l’évasion fiscale s’élèvent à près de 100 milliards d’euros. Après cette description de l’échec du système fiscal actuel, cet article analyse les régimes alternatifs tels que l’assiette commune consolidée pour l’impôt sur les sociétés (ACCIS) et conclut avec la perspective d’un impôt des sociétés européen comme véritable ressource propre pour le budget de l’UE.

La conception atemporaliste de la création dans les débats de philosophie analytique contemporaine
Authors: Clavier Paul
Published: October 2018

Longtemps éclipsée, la question de la compatibilité de la (pre)science divine avec la liberté a été exhumée dans les débats de philosophie analytique. Les promoteurs de la logique temporelle ont proposé un argument d’incompatibilité qui continue d’exercer la sagacité des commentateurs. L’objet de cet article est de suggérer que la conception atemporaliste de Dieu, dont on explique pourquoi elle est si peu en vogue aujourd’hui, est à même, sinon de résoudre complètement, au moins d’atténuer considérablement ces problèmes de compatibilité, qui rejoignent le problème de l’articulation de la souveraineté absolue de Dieu avec la contribution authentique des causes secondes.
Félix Hedde (1879-1960)
Authors: Bùi Thiện Thảo Jérôme
Published: October 2018

Mgr Félix Hedde (1879-1960), o.p., est un personnage-clé de la mission des dominicains de Lyon dans le Haut-Tonkin. Son long ministère au Việt Nam (1926-1960) en fit un témoin privilégié d’une période dramatique de l’histoire du pays. Il a connu les années prospères de la colonisation française jusqu’en 1940, les souffrances de ses compatriotes pendant la Seconde Guerre mondiale et la guerre d’Indochine, leur humiliation face à la décolonisation forcée, et enfin la persécution ouverte ou larvée des chrétiens sous le régime communiste. Chez Félix Hedde, l’amour pour la mission du Tonkin, le désir d’y implanter l’Église, se conjuguait à sa volonté d’honorer ses traditions familiales et nationales. L’épreuve de l’occupation japonaise, de la guerre d’Indochine, des défaites de l’armée française, autant que le réconfort de la fidélité des chrétiens vietnamiens de la mission dans une situation de plus en plus critique, détachant Mgr Hedde de ses rêves patriotiques, le conduisirent à l’accomplissement de sa vocation missionnaire. Les conditions particulières de son territoire de mission, où les ethnies montagnardes sont très largement majoritaires, l’amenèrent cependant à proposer pour lui succéder le Français André Jacq, privant ainsi d’évêque les chrétiens du lieu, de 1958 à 1990.

L’article tente d’éclairer un monde en transformation – le monde rural – et d’en délimiter les contours et les problématiques. L’action sanitaire et sociale qui est mise en place doit accompagner depuis plus de quarante ans une évolution profonde des territoires et des espaces de vie, qui voit la « campagne » se réduire au profit d’une périurbanisation. Ces modifications de l’espace, mais aussi des modes de vie, engendrent des problématiques nouvelles et spécifiques comme la mobilité. Comment les travailleurs sociaux s’emparent-ils de ces évolutions, et des enjeux qui les accompagnent ? Cet article introduit donc la problématique générale du présent numéro.

Les services d’action sanitaire et sociale de la msa : une implication forte en milieu rural
Authors: Lachesnaie Bruno , Garandel Anne-Lise
Published: October 2018

Depuis les années 1970, il a été observé un accroissement de l’isolement physique et social et une diminution de la population active agricole, le vieillissement de l’ensemble de la population rurale, une perte de vitalité (attractivité, qualité de vie) et de cohésion sociale de certains territoires ruraux. C’est la raison pour laquelle la Mutualité sociale agricole ( msa ), deuxième régime de protection sociale de France, a opéré, dès les années 1980, un élargissement de sa politique d’action sociale centrée jusqu’alors sur les publics agricoles vers une politique s’intéressant aux problématiques multiples générées par une déstructuration/recomposition des espaces ruraux. Les services d’action sanitaire et sociale de la msa conduisent aujourd’hui des missions d’accompagnement social individuel et collectif, d’ingénierie sociale et de conduite de projets de développement social.

Published: October 2018

BACKGROUND AND OBJECTIVE:

To investigate the effects of antiangiogenic drugs on the transcription profile of acetylation genes in immortalized human retinal pigment epithelium cells (ARPE-19) in vitro.

MATERIALS AND METHODS:

This in vitro study evaluated the effect of antiangiogenic drugs on the expression of histone acetylation genes on immortalized ARPE-19 cell cultures. ARPE-19 cells were cultured, plated, and treated for 24 hours with aflibercept (Eylea; Regeneron, Tarrytown, NY), ranibizumab (Lucentis; Genentech, South San Francisco, CA), or bevacizumab (Avastin; Genentech, South San Francisco, CA) at one (1×) or two times (2×) the concentrations of the clinical intravitreal dose. Untreated cells were used as controls. RNA was isolated, and real-time quantitative reverse transcription polymerase chain reaction analysis was performed on individual samples to quantify expression levels of genes associated with epigenetic acetylation pathways: histone acetyltransferase 1 (
HAT1
) and histone deacetylases 1, 6, and 11 (
HDAC1
,
HDAC6
, and
HDAC11
). Differences in cycle thresholds (ΔΔCts) were obtained, and folds were calculated using the formula 2
^ΔΔCt
. Main outcome measures were expression levels of candidate genes in treated versus untreated samples.

RESULTS:

Compared with untreated cells, 1× ranibizumab-treated cells expressed higher levels of
HDAC6
, and 2× ranibizumab-treated cells expressed higher
HDAC11
levels. Bevacizumab-treated (1×) cells had significant change in
HDAC1
,
HDAC6
, and
HDAC11
. In cultures treated with 2× bevacizumab, only
HDAC11
expression levels were significantly affected compared with controls. Aflibercept-treated (1×) cells had changes in expression of
HDAC1
,
HDAC6
, and
HDAC11
. At 2× concentration, only
HDAC11
was significantly changed.

CONCLUSION:

Our results show that antiangiogenic drugs can affect the transcription profile of genes regulating the histone acetylation status in ARPE-19 cells in vitro. This finding may have an implication in differential patient response to anti-vascular endothelial growth factor therapy by means of possible interactions between treatment and patient's epigenomic profile.

Efectos de la irradiación solar concentrada en las transformaciones alotrópicas del acero inoxidable AISI 316
Authors: Álvarez Omar , Rojas Armando , Barba Arturo , Arancibia Camilo A. , Álvarez Jorge , Melo Dulce V. , Arreola Carlos E.
Published: October 2018

Se investiga la transformación de fases que pueden ocurrir en un acero austenítico (AISI 316) mediante la demostración de la aparición de ferrita-δ que se obtiene en ciclos iniciales de calentamiento usando irradiación solar concentrada (ISC) a magnitudes necesitadas para obtener temperaturas de operación de sistemas de tipo torre central. Cuatro especímenes de acero inoxidable AISI 316 cortados de una misma pieza, fueron expuestos a ISC en el Horno Solar de Alto Flujo Radiativo de la Universidad Nacional Autónoma de México para desarrollar el ciclado térmico. El acero AISI 316 fue seleccionado por ser reportado entre los materiales más baratos usado en receptores de ISC. Pruebas de resistencia a la tensión monotónica demostraron que no existe un efecto relevante del ciclado térmico en las propiedades mecánicas resultantes. Las transformaciones de fase fueron caracterizadas usando microscopía óptica, difracción de rayos X, y microscopía electrónica de barrido con espectroscopía de dispersión de energía de rayos X. La aparición de la fase de ferrita-δ fue la principal diferencia entre los especímenes tratados con ISC y dos especímenes de referencia. La fracción UV de la ISC demostró tener el potencial de lograr estas transformaciones de fase a una temperatura cercana a los 630 °C.
Une nouvelle tradition : la céramique algéroise à l’aube du xxe siècle
Authors: Álvarez Dopico Clara Ilham
Published: October 2018

L’architecture néo-mauresque et la transformation des grandes demeures suburbaines d’époque ottomane à Alger, donne naissance, à la fin des années 1880, à une production de céramique historiciste, qui décline à partir des années 1920. Il est question ici du milieu algérien – collectionneurs, architectes, industriels, historien – qui, revendiquant la tradition, permet l’essor de cette nouvelle industrie d’art. L’article présente une expérience éphémère de rénovation, plutôt création, de l’artisanat algérois : l’atelier de céramique ouvert, entre 1899 et 1901, au musée des Arts et des Antiquités à Mustapha sous la direction du conservateur Georges Marye et de l’écrivain Émile Violard.
Tlemcen ou la source des sources
Authors: Sanson Hervé
Published: October 2018

L’ouvrage Tlemcen ou les lieux de l’écriture de l’écrivain algérien d’expression française Mohammed Dib, publié en 1993, est une œuvre singulière : associant photographies prises par le jeune Dib au lendemain de la guerre aux photographies prises quasiment cinquante ans plus tard par le photographie français Philippe Bordas, l’opus est prétexte pour l’écrivain à une exploration par l’écriture d’une ville spécifique, Tlemcen, et des strates mémorielles qui la composent. Mais c’est aussi à une exploration de l’œuvre dibienne que cet ouvrage invite : faire le portrait de Tlemcen, entreprise par essence infinie, consiste à faire le portrait d’une écriture.

Critical Thinking of Human Resources in the Goal
Authors: Galli Brian J.
Published: October 2018

Recently, changes within the business industry have led to human resource management (HRM) positions and structures being reconsidered. Human resources (HR) used to be centralized, but the constant changes to organizational culture has caused HR to become decentralized. The HR operations have been incorporated into other departments, as well. Now, HRM is essential to business processes that mirror other departments, such as accounting and finance, but HR is still centralized in specialized areas, such as recruitment and compensation. Examining Goldratt & Cox's “The Goal” reveals its involvement with HRM. This study evaluates the implication of HRM on a business, its relationship to the Theory of Constraints (TOC), and the ways in which these concepts can aid a business in reaching its main objective.
