Published: September 2018

A cultura do trigo (Triticum aestivum L.), tem relevante importância no mundo. Ao longo dos tempos, com o surgimento de doenças, foram desenvolvidas pesquisas para buscar a melhor eficiência no controle desses patógenos. Para obter resultados de melhor eficiência em aplicação curativa de fungicidas, o presente trabalho objetivou avaliar técnicas de pulverização sobre o depósito de gotas nas folhas da cultura. Foram realizados dois experimentos na área experimental da FCA/UNESP – Campus de Botucatu, sendo divididos em duas áreas: área de agricultura e área cascalheira. No Experimento I utilizou-se o esquema fatorial 3 x 2, com quatro repetições; foram dispostos três níveis de ar (0; 15; 29 km h-1), dois volumes de pulverização (100 L ha-1 e 200 L ha-1). No Experimento II foram três níveis de ar (0; 15; 29 km h-1) e dois ângulos diferentes de inclinação das pontas de pulverização em relação a cultura (0° e 30°). Nos estádios de segundo nó visível com 53 dias após semeadura (DAS) e emborrachamento completo 67 DAS foram realizadas pulverizações com fungicida triazol (tebuconazole). No Experimento I, na aplicação realizada aos 53 DAS, o tratamento com 200 L ha-1 com 29 km h-1 foi mais eficiente, para o Experimento II o melhor resultado foi obtido aos 67 DAS com ângulo de 30° e vento de 15 km h-1. Com base no estudo realizado torna-se possível alcançar melhor controle curativo dos patógenos que possam se instalar na cultura.

Published: September 2018

O tomate é uma das hortaliças tipo fruto mais populares do Brasil. Desta forma, torna-se de suma importância realizar pesquisas para garantir produtividade e frutos de alta qualidade. Objetivo do trabalho foi avaliar diferentes doses de ácidos húmicos e fúlvicos sobre o crescimento e produtividade do tomateiro cultivado com diferentes densidades de plantio. O experimento foi realizado na fazenda da Universidade Estadual de Goiás (UEG), Campus de Ipameri. Foi adotado os espaçamentos de 0,30 e 0,50 m entre plantas, correspondendo, respectivamente, às populações de 33.333 e 20.000 plantas ha-1; com as diferentes doses (0, 20, 40, 60 e 80 L ha-1) de ácidos húmicos e fúlvicos. O delineamento experimental utilizado foi de blocos casualizados em esquema fatorial 2 x 5 (espaçamentos x doses de ácidos) com quatro repetições. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de probabilidade. A produtividade do tomateiro foi maior no espaçamento de 0,50 cm, e as doses crescentes de ácidos húmicos e fúlvicos influenciaram positivamente no teor de clorofila e na firmeza do tomate de mesa. Conclui-se que para o adequado cultivo do Híbrido Santy, recomenda-se a densidade de plantio de 20.000 plantas ha-1 e doses crescentes de substâncias húmicas que assim garantem alta produtividade e qualidade dos frutos.

Published: September 2018

O presente trabalho teve por objetivo avaliar a resposta de plantas de milho submetidas a diferentes fontes de adubos nitrogenados. O experimento foi conduzido em um delineamento em blocos casualizados (DBC), com quatro tratamentos e cinco repetições, totalizando 20 parcelas. Os tratamentos usados foram: T1= controle (sem aplicação de N), T2= 300 kg ha-1 de sulfato de amônio (18% de N), T3= 200 kg ha-1 de ureia (45% de N) e T4= 2 L ha-1 de Fortune® (20% de N), os quais foram aplicados em adubação de cobertura via solo e via foliar, conforme especificidade de cada produto, entre os estádios fenológicos V6 e V8. Os parâmetros avaliados foram: clorofila total (SPAD), diâmetro de espigas (cm), número de fileiras de grãos por espiga, massa de grãos por espiga (g), comprimento de espigas (cm) e produtividade de grãos (kg ha-1). O tratamento T3 foi superior a todos os parâmetros avaliados, exceto quanto ao número de grãos por espiga que não apresentou diferenças estatísticas para nenhum tratamento. Concluiu-se que de fato, a demanda por N pelas plantas de milho é muito alta e que a mesma responde bem a adubação de cobertura com ureia e sulfato de amônio e que o fertilizante foliar Fortune® aplicado via foliar, pode contribuir para incremento na produtividade da cultura do milho, mas não consegue suprir a demanda de N pela cultura, quando aplicado como única forma de fornecimento de N inorgânico às plantas.

Published: September 2018

O mofo branco, causado por Sclerotinia sclerotiorum, é uma doença muito importante para muitas culturas agrícolas e seu controle tem sido feito por meio da adoção de medidas de forma integrada. Foi avaliada a ação antifúngica de um fertilizante foliar preparado com óleo essencial da casca de laranja (Orobor N1®: nitrogênio 1%, boro 0,22 %) sobre o crescimento micelial e germinação carpogênica de S. sclerotiorum. Os experimentos foram conduzidos em delineamento inteiramente casualizados, em esquema fatorial, utilizando-se cinco isolados do patógeno e seis concentrações do fertilizante foliar. Na avaliação do crescimento micelial, discos de BDA (6 mm) com micélio fúngico, foram depositados em placas de Petri contendo a mistura de BDA com o produto nas concentrações de 0, 50, 100, 150, 200 e 250 mL.100 L-1 de água. Mediram-se diariamente os dois diâmetros ortogonais da colônia, até que o tratamento testemunha colonizasse todo o meio de cultura. Na germinação carpogênica, depositaram-se 16 escleródios/caixas gerbox contendo solo umedecido a 62% da capacidade de campo (CC). Em seguida, foram adicionadas as respectivas concentrações do produto, atingindo assim 100% da CC do solo. As avaliações ocorreram aos 30, 45, 60 e 75 dias, mensurando o número de escleródios germinados, estipes e apotécios formados. Verificou-se que o fertilizante foliar inibiu o crescimento micelial, reduziu a formação de escleródios e não reduziu a germinação carpogênica de S. sclerotiorum.

Published: September 2018

A espécie humana pode estar progressivamente gerando mudanças catastróficas ao ambiente natural. Muitas vezes, estas consequências são atribuídas à natureza ou à ação natural do tempo (como o aquecimento global e degelo das áreas glaciais). No entanto, não se dão por conta que a própria sociedade vem “orquestrando uma sinfonia de desastres”, em prol da comodidade e satisfação. O objetivo deste trabalho pretende expor pontos impactantes de uma situação-problema, como é o assoreamento nas nascentes, nos rios, riachos, aterramento total ou parcial de lagoas, contribuindo rapidamente para aumento da extensão do mar, na área do litoral paraibano, nordeste do Brasil. As observações nos locais de estudo podem evidenciar: ocupações irregulares em ambientes aquíferos de superfície que foram aterrados; somadas às chuvas que ocorrem de forma abundante durante todo o ano no litoral do estado da Paraíba, que podem contribuir diretamente para a lixiviação de materiais (sedimentos). Estes materiais terão seu destino final o mar, proporcionando o assoreamento. O fenômeno da progradação na costa brasileira mostra que essas situações impactantes podem ser ocasionadas pelo homem, sendo notório que essas modificações diversas a curto ou em longo prazo poderão causar danos. Desta forma, esta pesquisa busca trazer informações importantes sobre o tema, e sugerir medidas de prevenção e/ou mitigação, a fim de evitar os efeitos da degradação.

Forms of livelihood of Can Gio residents, Ho Chi Minh City: the interaction between factors of policy, market and environment
Authors: Ngo Lan Thi Phuong
Published: September 2018

When doing research on the livelihood of human groups and communities, many studies have shown that the environment exerts important impacts on the forms of livelihood (Julian Steward 1955). Accordingly, the environment will provide capacities for the survival of man. However, from another perspective, studies have also shown that the choice of the forms of livelihood or economic thinking of ethnic groups or other groups is governed by such other factors as history, culture, psychology of ethnic groups or religion (Jared Diamond 1997, Charles Keyes 1983, McElwee 2007). This leads to the current state where, though in the same environment, ethnic groups possess different livelihood forms. Analysing the livelihoods of Can Gio residents, Ho Chi Minh City in today’s context of modern society, the paper’s author believes that livelihood forms of the residents of this land results from the interaction between economic-political and ecological factors. Specifically, the livelihood activities of the residents here, in the context of contemporary social management, are affected by the government’s economic development policy factors, market demands and ecological factors which are inherently understood as providing specific capabilities for human survival at a specific environment. In this interaction, the ones between factors of policy, environment and market control the shaping of livelihood forms of the residents. Depending on the characteristics of each profession, the impact level of each factor varies.
Nguyen Du – a marvelous matchmaker in literature
Authors: Nguyen Xuan Thi Thanh
Published: September 2018

Nguyen Du entered the literature world as an experienced genius. Being a highly sensitive person, living in the chaotic times and going through many vicissitudes, the poet Nguyen Du was always anxious. However, those almost constant anxieties seemed to be transformed into the power, into the sublime (with the meaning given by Sigmund Freud) which in some moments helped the poet get into the calmness overcoming his ordinary ego. It was the calmness coming from the poetical creativity. In his calmness of creativity, Nguyen Du made the marvelously cultural matches. My paper focuses on seven matches in Nguyen Du’s works as of the following: (1) Vietnam and China, (2) Buddhism and Confucianism, (3) Man and Nature, (4) Vulgarity and Holiness, (5) Poetry and Novel, (6) Romanticism and Realism, (7) Traditionality and Modernity. The contents, the manners and the characteristics of those cultural matches could light up the cultural mind, the aesthetic perception and the intertextual tendency of Nguyen Du as representative of Vietnamese literature.

Published: September 2018

Fulltime students have more free time than working students. They can spare a lot of time on doing tasks from their lecturers and spend the rest to play or to do any other activity they like. While working students must share their time wisely to make a balance of studying and working. The hardship of balancing these two states in some ways, affects students’ achievement in class. To get better achievement, there are many influencing factors. One of them is motivation. Coming across this situation, it becomes an interesting matter to find out correlation of students’ employment status and achievement, students’ motivation and achievement, and correlation of students’ employment status and motivation simultaneously on achievement.  Keywords: Correlation, Employment Status, Motivation, Achievement.

‘Colonial livery’ and the chemise à la reine, 1779–1784
Authors: Ashelford Jane
Published: September 2018

When Jane Austen wrote in January 1801 that ‘Mrs Powlett was at once expensively and nakedly dressed’, the fashion for muslin dresses had existed for some eighteen years. This article examines the crucial period between 1779 and 1784 when the muslin garment, which became known as the chemise à la reine, was developed and refined. Originating in the French West Indies, the gaulle was the ‘colonial livery’ worn by the wives of the white elite, the ‘grands blancs’, and first appeared as a costume in a ballet performed in Paris in 1779. The version worn by Queen Marie Antoinette in Vigée Le Brun's controversial portrait of 1783 provoked, according to the Baron de Frénilly, ‘a revolution in dress’ which eventually destabilized society. The article focuses on the role played by Saint-Domingue, France's most valuable overseas possession, in the transference of the gaulle from colonial to metropolitan fashion, and how the colony became one of the major providers of unprocessed cotton to the French cotton industry.
Enhanced antineoplastic/therapeutic efficacy using 5-fluorouracil-loaded calcium phosphate nanoparticles
Authors: Mohiyuddin Shanid , Naqvi Saba , Packirisamy Gopinath
Published: September 2018

In the past few decades, the successful theranostic application of nanomaterials in drug delivery systems has significantly improved the antineoplastic potency of conventional anticancer therapy. Several mechanistic advantages of nanomaterials, such as enhanced permeability, retention, and low toxicity, as well as surface engineering with targeting moieties, can be used as a tool in enhancing the therapeutic efficacy of current approaches. Inorganic calcium phosphate nanoparticles have the potential to increase the therapeutic potential of antiproliferative drugs due to their excellent loading efficiency, biodegradable nature and controlled-release behaviour. Herein, we report a novel system of 5-fluorouracil (5-FU)-loaded calcium phosphate nanoparticles (CaP@5-FU NPs) synthesized via a reverse micelle method. The formation of monodispersed, spherical, crystalline nanoparticles with an approximate diameter of 160–180 nm was confirmed by different methods. The physicochemical characterization of the synthesized CaP@5-FU NPs was done with transmission electron microscopy (TEM), dynamic light scattering (DLS), field emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The antineoplastic potential of the CaP@5-FU NPs against colorectal and lung cancer cells was reported. The CaP@5-FU NPs were found to inhibit half the population (IC50) of lung adenocarcinoma (A549) cells at 32 μg/mL and colorectal (HCT-15) cancer cells at 48.5 μg/mL treatment. The apoptotic induction of CaP@5-FU NPs was confirmed with acridine orange/ethidium bromide (AO/EB) staining and by examining the morphological changes with Hoechst and rhodamine B staining in a time-dependent manner. The apparent membrane bleb formation was observed in FE-SEM micrographs. The up-regulated proapoptotic and down-regulated antiapoptotic gene expressions were further confirmed with semiquantitative reverse transcriptase polymerase chain reaction (PCR). The increased intracellular reactive oxygen species (ROS) were quantified via flow cytometry upon CaP@5-FU NP treatment. Likewise, the cell cycle analysis was performed to confirm the enhanced apoptotic induction. Our study concludes that the calcium phosphate nanocarriers system, i.e. CaP@5-FU NPs, has higher antineoplastic potential as compared to 5-FU alone and can be used as an improved alternative to the antimitotic drug, which causes severe side effects when administrated alone.
Synthesis of eunicellane-type bicycles embedding a 1,3-cyclohexadiene moiety
Authors: Frichert Alex , Jones Peter G , Lindel Thomas
Published: September 2018

The first synthesis of diterpenoid eunicellane skeletons incorporating a 1,3-cyclohexadiene moiety is presented. Key step is a low-valent titanium-induced pinacol cyclization that proved to be perfectly diastereoselective. Determination of the relative configuration of the diol was aided by the conversion to the diastereomer by oxidation and reduction. Conformational analysis of some of the resulting diols obtained under McMurry conditions was complicated by the presence of several conformers of similar energy. The pinacol coupling appears to start at the ketone, as indicated by the selective reduction of non-cyclizing cyclohexane systems that were synthesized from limonene oxide. The title compounds and their synthetic precursors are prone to aromatization on contact with air oxygen. Attempted synthesis of cyclohexene-containing eunicellane bicycles by elimination of water from tertiary alkynyl carbinols afforded novel allene systems. Our study may be of help towards the total synthesis of solenopodin or klysimplexin derivatives.
Gradients of Synchrotron Polarization: Tracing 3D Distribution of Magnetic Fields
Authors: Lazarian A. , Yuen Ka Ho
Published: September 2018

We describe a new technique for probing galactic and extragalactic 2D and 3D magnetic field distribution using gradients of polarized synchrotron emission. The fluctuations of magnetic field are elongated along the ambient magnetic field. Therefore, the field variations are maximal perpendicular to the B-field. This allows tracing the B-field with synchrotron polarization gradients. We demonstrate that the Faraday depolarization allows us to map 3D B-field structure. The depolarization ensures that the polarization gradients sample the regions close to the observer with the sampling depth controlled by the frequency of radiation. We also analyze the B-field properties along the line of sight (LOS) by applying the gradient technique to the wavelength derivative of synchrotron polarization. This Synchrotron Derivative Polarization Gradients technique can recover the 3D vectors of the underlying B-fields. The new techniques are different from the Faraday tomography, as they provide a way to map the 3D distribution of B-field components perpendicular to the LOS. In addition, we find that the alignment of gradients of polarization with the synchrotron polarization can be used to separate the contribution of the foreground from the polarization of cosmological origin. We notice that the same alignment is also present for the dust polarization.
Time Variations of the Nonpotential and Volume-threading Magnetic Helicities
Authors: Linan L. , Pariat É. , Moraitis K. , Valori G. , Leake J.
Published: September 2018

Relative magnetic helicity is a gauge-invariant quantity suitable for the study of the magnetic helicity content of heliospheric plasmas. Relative magnetic helicity can be decomposed uniquely into two gauge-invariant quantities, the magnetic helicity of the nonpotential component of the field and a complementary volume-threading helicity. Recent analysis of numerical experiments simulating the generation of solar eruptions have shown that the ratio of the nonpotential helicity to the total relative helicity is a clear marker of the eruptivity of the magnetic system, and that the high value of that quantity could be a sufficient condition for the onset of the instability generating the eruptions. The present study introduces the first analytical examination of the time variations of these nonpotential and volume-threading helicities. The validity of the analytical formulae derived are confirmed with analysis of 3D magnetohydrodynamics (MHD) simulations of solar coronal dynamics. Both the analytical investigation and the numerical application show that, unlike magnetic helicity, the nonpotential and the volume-threading helicities are not conserved quantities, even in the ideal MHD regime. A term corresponding to the transformation between the nonpotential and volume-threading helicities frequently dominates their dynamics. This finding has an important consequence for their estimation in the solar corona: unlike with relative helicity, their volume coronal evolution cannot be ascertained by the flux of these quantities through the volume’s boundaries. Only techniques extrapolating the 3D coronal field will enable both the proper study of the nonpotential and volume-threading helicities and the observational analysis of helicity-based solar-eruptivity proxies.

Previous findings show that the existence of dense cores or bulges is the prerequisite for quenching a galaxy, leading to a proposed two-step quenching scenario: compaction and quenching. In this scenario, galaxies first grow their cores to a stellar mass surface density threshold, and subsequently quenching occurs, suggesting that galaxies evolve from extended star-forming galaxies (eSFGs), through compact star-forming galaxies (cSFGs), to a quenched population. In this work, we aim at examining the possible evolutionary link between eSFGs and cSFGs by identifying the trends in star formation rate (SFR), gas-phase metallicity, and H I content, since one would naturally expect that galaxies evolve along the track of cold gas consumption and metal enhancement. We select a volume-limited sample of 15,933 galaxies with stellar mass above

and redshift of

from the NASA Sloan Atlas catalog within the ALFALFA footprint. The cSFGs on average exhibit similar or slightly higher SFRs of ∼0.06 dex and significantly higher gas-phase metallicity (up to 0.2 dex at low mass) with respect to the eSFGs, while the cSFGs dominate the galaxy population of the most intense star formation activities. More importantly, overall the median H i content and gas depletion time of cSFGs are about half of eSFGs. Our result supports the compaction and quenching scenario that galaxies evolve and grow their cores along the track of cold gas consumption and metal enhancement. The environments of eSFGs and cSFGs are indistinguishable, suggesting that the compaction process is independent of any environmental effects at least for the low-redshift universe.
The fishing mantid: predation on fish as a new adaptive strategy for praying mantids (Insecta: Mantodea)
Authors: Battiston Roberto , Puttaswamaiah Rajesh , Manjunath Nayak
Published: September 2018

Observations in unmanipulated, semi-natural conditions were made of a single individual of the praying mantid Hierodulatenuidentata, while hunting and capturing an unusual prey for this kind of insect, guppy fish, Poeciliareticulata. This repetitive fishing behavior, recorded daily, is reported here for the first time and discussed in relation to the adaptive behavioral plasticity of praying mantids. We speculate regarding learning from experience as a hunting strategy.
Du fils de Dieu au Père du peuple. Des rapports équivoques entre le marxisme et les religions
Authors: Robelin Jean
Published: September 2018

Si l’inspiration initiale des marxismes conduisait à rendre la religion à sa référence sociale et à briser le bloc théologico-politique, le marxisme stalinien a abouti à l’érection de la doctrine en religion laïque. La dissolution de cette sacralisation conduit à une problématique de la laïcité opposant aux religions du pouvoir, les effets impolitiques des religions.
Le SIRH peut-il être un outil de communication de proximité ?
Authors: Comtet Isabelle , Chassigneux Sandrine
Published: September 2018

La fonction RH est aujourd’hui en partie décentralisée auprès des managers de proximité afin d’avoir une meilleure connaissance du terrain et de l’activité professionnelle des collaborateurs. Pour rééquilibrer les actions de chacun des acteurs, proposer des solutions de facilitation pour les gestionnaires des ressources humaines, favoriser l’implication des managers dans le fonctionnement de leurs équipes, le SIRH semble un véritable dispositif d’optimisation de la gestion des RH au service de l’entreprise. Mais que reste-t-il aux relations interpersonnelles entre collaborateurs ? Que devient la part de « l’humain » spécifique à la gestion des ressources « humaines » ? ; Qu’en est-il du manager et de son rôle essentiel de relai, de partage de sens ? Le SIRH ne serait-il pas une fausse bonne idée ?
Conditions d’acceptabilité d’une technologie de domotique dans les contextes professionnels de service
Authors: Barnier Frédérique , Chekkar Rahma
Published: September 2018

La recherche, relatée dans cet article, tente de comprendre comment se construit l’acceptabilité des TIC dans les contextes professionnels de service. Dans cet objectif, les auteurs se basent sur les données issues d’une enquête d’acceptabilité conduite sous la forme d’entretiens semi-directifs auprès de 83 professionnels exerçant dans des organisations de service au sujet d’une technologie de domotique. La recherche met en évidence trois dimensions que peut revêtir l’acceptabilité d’une technologie : acceptabilité fonctionnelle, acceptabilité financière et acceptabilité socio-éthique. Elle montre, par ailleurs, l’influence de facteurs intrinsèques individuels et organisationnels sur le raisonnement qui sous-tend l’acceptabilité des technologies.

Authors: Hassani Nadia
Published: September 2018

Dans une démarche empirique visant à produire un savoir à visée scientifique inédit dans le champ des Sciences de l’Information et de la Communication, et à l’appui d’une enquête qualitative et quantitative menée en ligne auprès de 60 Chief Happiness Officers (CHO) français via le réseau social numérique professionnel LinkedIn, l’objet de notre contribution est d’analyser les stratégies communicationnelles et les concepts interactionnistes mis en œuvre par les CHO pour mesurer et améliorer le bien-être de leurs collaborateurs, et d’étudier dans quelles mesures l’usage des NTIC participe in fine à leur propre « bonheur au travail ».
Qui regarde quoi ?
Authors: Marcelli Daniel
Published: September 2018

À partir de la lecture du tableau bien connu du Caravage Narcisse , tableau où peuvent se lire des déplacements, des décalages, des dissimulations et des tromperies, l’auteur fait le parallèle avec la situation du jeune enfant dans les bras parentaux qui, pour la première fois, est « présenté devant le miroir ». Là aussi, il s’y joue des décalages du regard, des tromperies, des surprises. Pour l’auteur, ces mouvements constituent l’essence même du narcissisme, une ombre jamais saisissable, toujours décalée et porteuse d’une inéluctable part de méconnaissance. Le jeu de réflexion entre ce Narcisse dont on peut se demander ce qu’il contemple et le jeu des regards entre parents et enfants devant le miroir représente une excellente métaphore de la construction précoce du narcissisme.
Adoption, miroirs et reflets narcissiques
Authors: Farkas Olivia
Published: September 2018

Recevoir des candidats lors d’entretiens pré-agréments, ou bien des parents et des enfants liés par la filiation adoptive, dévoile de nombreux enjeux narcissiques variés qui se partagent et qui peuvent se heurter. Il est intéressant de pouvoir les écouter et les laisser se déployer lors de nos entretiens, percevant leurs multiples reflets dans les histoires particulières des sujets que nous rencontrons.
Apprentissage du brossage dentaire chez des enfants présentant un trouble du spectre autistique : effets de l’utilisation de tablettes tactiles
Authors: Lefer Gaëlle , Bourdon Patrice , Mercier Cendrine , Lopez-Cazaux Serena
Published: September 2018

Objectif : L’objectif de cette étude exploratoire est d’évaluer les effets à court terme (quatre mois) d’un programme d’apprentissage du brossage dentaire, utilisant des pictogrammes proposés via l’application numérique çATED conçue pour des patients présentant un trouble du spectre autistique (TSA). Méthodes : Cinquante-deux patients avec TSA, âgés de 3 à 19 ans, issus de sept structures éducatives, ont été inclus. Un programme d’entraînement au brossage est proposé en lien avec les équipes éducatives. Des évaluations sont effectuées à partir de grilles d’observation où sont évaluées l’autonomie lors du brossage dentaire et les interactions avec la tablette. Résultats : Les résultats montrent une amélioration du brossage dentaire. Les enfants progressent dans l’acquisition des diverses étapes du brossage, même si certaines étapes restent difficiles à effectuer. Les interactions avec la tablette sont aussi plus nombreuses, ce qui encourage l’utilisation de cet outil dans l’apprentissage du brossage dentaire. Conclusions : L’accompagnement des enfants de façon quotidienne permet d’améliorer la réalisation du brossage dentaire, ce qui participe à la prise en charge préventive de ces patients. L’usage d’une tablette tactile en contexte dentaire et notamment pour l’apprentissage du brossage est simple et efficient.
Élaboration des normes de prévention : une réflexion éthique nécessaire
Authors: Pagani Victoria , Alla François , Cambon Linda , Claudot Frédérique
Published: September 2018

Introduction : La santé publique tenterait de modifier les normes sociales existantes en mettant en place des stratégies favorisant l’émergence de normes plus propices à son objectif de bonne santé et de bien-être. Les politiques de prévention et les interventions qui en découlent, en s’intéressant aux comportements de santé, chercheraient à modifier les « habitus » des individus et contribueraient à définir de nouvelles manières d’être, d’agir et de vivre. La prévention met ainsi en jeu de nombreuses valeurs personnelles, culturelles, sociétales et collectives. Ces démarches ne peuvent ainsi s’affranchir d’un questionnement éthique sur leur sens, leur bien-fondé et leur justice. L’objectif de cette étude est de caractériser la prise en compte d’une réflexion éthique lors de la création de la norme de santé publique. Méthodes : Pour répondre à l’objectif, une revue narrative a été conduite. Elle a été effectuée à partir de la base de données Web of Science, celle-ci permettant de couvrir des revues des différents champs disciplinaires concernés. Résultats : Trente-quatre publications ont été retenues qui objectivent de nombreuses définitions et types de normes utilisées par la santé publique dans ses stratégies d’intervention. Un grand nombre d’acteurs intervient dans le processus de création d’une norme de santé publique : spécialistes, leaders d’opinion, acteurs sociaux. Enfin, si certaines publications mettent en avant que l’utilisation de la norme en prévention soulève certains questionnements éthiques, aucune publication ne fait référence à la présence d’une réflexion éthique structurée dans ce processus. Conclusion : Les interventions de prévention et les outils utilisés ne peuvent se passer d’une réflexion éthique. Comment faire pour « bien » faire ? Comment gérer les conflits de valeurs ? Ces questionnements sont nécessaires lorsque l’on conduit des politiques ou des programmes et peuvent orienter plus justement leurs stratégies et contribuer à favoriser leur acceptabilité et leur efficacité auprès des populations.
Les motivations des médecins généralistes en centres de santé. Enquête par entretiens
Authors: Ridard Elise , Somme Dominique
Published: September 2018

Objectifs : Les centres de santé (CDS) sont des structures de soins ambulatoires, mono- ou pluridisciplinaires, dont le personnel est salarié. Ils ont une vocation d’accessibilité sociale et financière. Depuis quelques années, de nouveaux CDS sont créés afin d’attirer des médecins généralistes. Pour que ces CDS puissent être une réponse à la désertification médicale, il faudrait connaître les motivations des médecins y travaillant, afin de déterminer s’il est possible d’amplifier ce phénomène. L’étude réalisée cherche à préciser les raisons qui orientent les médecins vers ce choix d’exercice et leurs motivations. Méthodes : Une étude qualitative, par entretiens individuels semi-directifs auprès de médecins exerçant dans des CDS des régions Bretagne et Pays de la Loire a été réalisée. Une analyse thématique des données a été effectuée. Résultats : Douze médecins généralistes ont été inclus. Les motivations principales sont le salariat et ses avantages, les conditions de travail intéressantes. Les échanges professionnels, souvent informels, sont valorisés. D’autres motivations apparaissent au second plan dans les entretiens : les médecins mettent en avant le service rendu à la population, l’accessibilité des CDS et leur sentiment de pouvoir y exercer une médecine de qualité. Conclusion : Ces motivations professionnelles peuvent être classées en motivations externes et internes. Afin de diffuser le modèle des CDS, d’y recruter des médecins, mais aussi de les fidéliser, les gestionnaires pourraient, en plus de proposer des conditions de travail attrayantes, développer le volet actions de santé publique, et améliorer leur communication pour faire connaître les CDS.
Análisis de la adscripcion a valores
Authors: Gobernado Arribas Rafael
Published: September 2018

Se desarrolla en este trabajo un esquema teórico que sirve para explicar la adscripción a valores. Ese esquema es generalizable a los demás componentes de la cultura, no sólo a los valores. La adscripción a valores puede explicarse por la biología, la personalidad, la sociedad y la cultura. En la cultura a su vez se encuentran tres elementos ligados también a la citada adscripción: los conocimientos, la cultura arbitraria y la coherencia cultural. El factor que explica con más éxito la adscripción a valores es la cultura arbitraria.
