Farmers’ Perception and Drivers of Membership in Rice Production Community Enterprises: Evidence from the Central Region, Thailand
Authors: Petcho Wachira , Szabo Sylvia , Kusakabe Kyoko , Yukongdi Vimolwan
Published: October 2019

In rapidly developing economies such as Thailand, farmers face multiple challenges preventing them from improving their livelihoods, and are therefore reverting to collective action as a means to overcome those obstacles. Community enterprises (CEs) have recently emerged as a new form of such collective action, yet there is limited evidence regarding farmers’ perception of rice production CEs (RPCEs) and the specific factors influencing their decision to join. In order to fill this gap, primary data were collected through questionnaires administered to 406 farmers in six districts in Uthai Thani province in the central region of Thailand. A weighted average index (WAI) was employed to assess the farmers’ perception of RPCEs’ role, and a binary logit regression model was used to investigate the determinants of perception and membership in RPCEs. The results revealed that both members and non-members perceived RPCEs as a saving source but not a credit provider. Compared to non-members, members put more emphasis on the product competition with rivals. Decision to join was associated with small landholdings, diversity of rice varieties cultivated, participation in networks, membership of economic groups, access to extension services, access to credit, and proximity to the market. The results suggest that production-oriented and marketing-oriented policies should be promoted in order to encourage farmers to cultivate organic rice and rice for the niche market to supply to RPCEs in order to generate greater group income.
International Tourists’ Loyalty to Ho Chi Minh City Destination—A Mediation Analysis of Perceived Service Quality and Perceived Value

Published: October 2019

At present, tourism is a key component of the modern Vietnamese economy. However, it is increasing the country’s pitifully low return visitor rate. The aim of this study was to explore the structural relationships among destination attributes, perceived service quality, perceived value, and loyalty of international tourists in Ho Chi Minh City. The destination attributes were investigated in terms of cultural and historical attractions, local cuisine, perceived price, safety and security, service facilities, natural environment, entertainment and recreation activities, negative attributes, and destination image. Data were collected through a self-administered questionnaire survey of 2073 respondents employed using SmartPLS analysis. The results indicate that destination attributes, perceived service quality, and perceived value have positive and direct influences on tourist loyalty. In addition, the findings also confirmed that these destination attributes indirectly affected tourist loyalty through their perceived value and perceived service quality. Based on the findings, some recommendations and implications are suggested to enhance traveler intention to re-visit and increase awareness of the necessity for sustainable development tourism in Ho Chi Minh City, with their willingness to recommend this place to others.
Implementing LEED v4 BD+C Projects in Vietnam: Contributions and Challenges for General Contractor
Authors: Pham Duy Hoang , Lee Joosung , Ahn Yonghan
Published: October 2019

Sustainable construction addresses both rising housing demand and the need to reduce energy consumption, but is not yet widespread in Vietnam, although the number of Green Building Certified projects has increased significantly since 2015, especially those with LEED certification. Certification adds value to the project but also incurs additional costs and implementation challenges for general contractors (GCs) and other stakeholders. The growing popularity of LEED buildings requires GCs to understand their role in fulfilling the LEED requirements. We therefore conducted a thorough review of the previous research on LEED v4 guidelines and their local equivalents to determine what is expected of GCs working on LEED v4 BD + C projects in Vietnam. A survey of 72 experts, engineers, and architects working in the construction sector identified the LEED tasks where Vietnamese GCs lack experience and suggested solutions to address this shortfall were developed. In particular, Vietnamese GCs lacked experience in implementing their sustainable roles. These results provide a useful foundation for Vietnamese GCs seeking to expand the scope of their LEED work and identified necessary training. Our findings will also guide future research to help GCs in Vietnam adapt to LEED’s sustainability requirements and support sustainable construction in Vietnam.

Published: October 2019

The selection and rational use of mechanization significantly affects the cost of agricultural products. To achieve the best financial effects, it is necessary to optimize the use of existing machine parks. The authors suggest a decision tree for deciding whether to ‘innovate or not’. The aim of the research is to define an algorithm that determines whether or not the land is arable, and in this way to help the owner of the family farm in the planning of working hours for agricultural machines, i.e., managing the machine park. The lack of plans, which stems from the lack of accurate data on the appropriate conditions of cultivation, leads to inappropriate use of time and the capacity of the machine park. The decision process is split into four compound variables: biological conditions, economic environment, technological conditions, and expertise and workmanship quality. Linguistic values of these variables are modeled with intuitionistic fuzzy sets, allowing for imprecision in data as well as experts’ hesitation.
Food Safety Event Detection Based on Multi-Feature Fusion
Authors: Xiao Kejing , Wang Chenmeng , Zhang Qingchuan , Qian Zhaopeng
Published: October 2019

Food safety event detection is a technique used to discover food safety events by monitoring online news. In general, a set of keywords are extracted as features to represent news, and then the news is clustered to generate events. The most popular method for news feature extraction is Term Frequency-Inverse Document Frequency (TF-IDF), however, it has some defects such as being prone to the “dimension disaster”, low computational efficiency, and a lack of semantic information. In addition, Latent Dirichlet Allocation (LDA) is also widely used in news representation. Despite its low dimension, it still suffers from some drawbacks such as the need to set a predefined number of clusters and has difficulty recognizing new events. In this paper, a method based on multi-feature fusion is proposed, which combines the TF-IDF features, the named entity features, and the headline features to represent the news. Based on the representations, the incremental clustering method is used to cluster the news documents and to detect food safety events. Compared with the traditional methods, the proposed method achieved higher Precision, Recall, and F1 scores. The proposed method can help regulatory authorities to make decisions and improve the reputation of the government, whilst reducing social anxiety and economic losses.

Published: October 2019

Sustainable engineering practices always provide an opportunity for engineers to produce long-term solutions. In the fields of construction and irrigation, soil bed formation symmetry is very important, especially in the case of its behavior with reference to water runoff, whether natural or artificial. In this study, different soil bed formations were tested with the help of advanced hydrology apparatus under severe rainfall conditions. A major focus was to observe the water retention and volume discharge with reference to soil combinations and slope level change. Furthermore, an advanced decision-making technique incorporating artificial neural networks (ANNs) was used to predict and explore the interrelationship behavior of different parameters. It was observed that ST-1 (100% clay) performed well as it tried to retain a large quantity of water (7.28 L/min), making it suitable for irrigation, while ST-2 (100% sand) performed better for structures, as sand tries to quickly drain water, thus retaining less water (0.16 L/min). Change of slope was also another factor; at a 3% slope level along with 100% clay, water resistance was higher as compared to sand. Soil type-3 (ST-3) helped in the retention of water even at a 3% soil bed slope. This study will help engineers and designers in the optimization of soil bed formation for construction and irrigation purposes.
Host Range of Bacteriophages Against a World-Wide Collection of Erwinia amylovora Determined Using a Quantitative PCR Assay
Authors: Gayder Steven , Parcey Michael , Castle Alan J. , Svircev Antonet M.
Published: October 2019

Erwinia amylovora is a globally devastating pathogen of apple, pear, and other Rosaceous plants. The use of lytic bacteriophages for disease management continues to garner attention as a possible supplement or alternative to antibiotics. A quantitative productive host range was established for 10 Erwinia phages using 106 wild type global isolates of E. amylovora, and the closely related Erwinia pyrifoliae, to investigate the potential regional efficacy of these phages within a biopesticide. Each host was individually infected with each of the 10 Erwinia phages and phage production after 8 h incubation was measured using quantitative real time PCR (qPCR) in conjunction with a standardized plasmid. PCR amplicons for all phages used in the study were incorporated into a single plasmid, allowing standardized quantification of the phage genome copy number after the infection process. Nine of the tested phages exhibited a broad host range, replicating their genomes by at least one log in over 88% of tested hosts. Also, every Amygdaloideae infecting E. amylovora host was able to increase at least one phage by three logs. Bacterial hosts isolated in western North America were less susceptible to most phages, as the mean genomic titre produced dropped by nearly two logs, and this phenomenon was strongly correlated to the amount of exopolysaccharide produced by the host. This method of host range analysis is faster and requires less effort than traditional plaque assay techniques, and the resulting quantitative data highlight subtle differences in phage host preference not observable with typical plaque-based host range assays. These quantitative host range data will be useful to determine which phages should be incorporated into a phage-mediated biocontrol formulation to be tested for regional and universal control of E. amylovora.
Phobia of the Introduction of Ethical Financing through Islamic Banking System in Nigeria: Respondents’ Perceptions on Business and Economic Suitability
Authors: Sabo Bello Hashim , Suleiman Galadima Ibrahim , Ibrahim Aliyu Baraka
Published: October 2019

This research work aimed at studying the business and economic suitability of the introduction of alternative ethical finance through Islamic banking system in Nigeria as being consistent with modern economies. As Islamic banking system is working in a number of countries, then, Nigeria shouldn’t be a battle ground between Muslims and Christians mostly because it carries the toga of Islam thereby ignoring the beneficial social goals inherent in the Islamic alternative modes of ethical financing and investments. The issue of interest is a philosophical question which has to do with the core concept of ‘is money a commodity that can be traded on its own or not? The central issue is that the contemporary financial system is exploitative, unjust,  discriminating, unstable and crisis generating. The sampling method adopted for the study was stratified random sampling technique. The study was conducted with 480 respondents in Abuja and responses elicited from questionnaires administered. The instrument used for data collection was questionnaire and data analysis made used of simple percentage and ANOVA was adopted for hypothesis testing. Data obtained was analyzed with inferential statistical technique. ANOVA was employed to test each hypothesis at 99 per cent confidence level. Results were analyzed through descriptive statistics  and hypotheses tested using ANOVA at 0.01 level of significance. Thus, this paper believes that the Islamic banking provides financial solutions that are not only concerned with the growth of money but the ethical means by which money can be used to generate wealth. The paper also believes that with the establishment of Islamic banking system in Nigeria therefore will relatively remedy the problems of interest banking system that are making unemployment and redundancy to becoming order of the day. This study suggested that the introduction of Islamic banking system in Nigeria might promote a balance between the social and economic aspects of human society, the self and social interests and between the individual, family, society and the State. It can effectively address issues like income distribution and poverty alleviation, which capitalism has not been able to address and at the global level, it will rid the basis of instability, so making the world a happier place with harmony among followers of various religions.

Published: October 2019

Este artigo visa refletir sobre a formação do professor de língua inglesa, a partir da análise da mudança curricular de um Curso de Licenciatura em Letras-Inglês, em uma universidade pública mineira. Fundamentamo-nos no pressuposto bakhtiniano de que a linguagem é dialógica e buscamos, com base em uma metodologia qualitativa de pesquisa, identificar alguns enunciados, no Projeto Pedagógico do Curso em questão, que apontassem para concepções do que seja formar um professor de língua inglesa. Nossas análises apontam que o eixo organizador das diferentes vozes colocadas em cena acerca da formação parece estar na necessidade de interpelar o licenciando a tomar um posicionamento diante das diversas concepções de língua(gem) que constituem sua profissão.
El principio de la buena fe y dineros pagados en exceso por la Administración Estatal: Un análisis de las sentencias del Consejo de Estado
Authors: Castillo Yara Esperanza
Published: October 2019

En el presente artículo se expondrán los criterios que han sido desarrollados en
la jurisprudencia del Consejo de Estado colombiano en torno a la no devolución
de dinero que fue pagado en exceso por parte de la Administración Estatal; en
este se describe cómo opera el Principio General del Derecho de la buena fe; para
tal fin se realizó un estudio de las sentencias que este alto Tribunal ha proferido
en los últimos diez años; es decir, en el periodo comprendido entre el año 2007
y 2017, lapso en el que han proliferado decisiones judiciales que resuelven este
tipo de pretensiones alzadas por las entidades estatales, específicamente al ser
incoado el medio de control de nulidad y restablecimiento del derecho, el cual ha
sido denominado por varios autores como acción de lesividad.

El efecto en el patrimonio del Estado no es tenido en cuenta en las decisiones
judiciales, dado que existe un enriquecimiento y un correlativo empobrecimiento
del tesoro público, siendo sin más la causa, el error de la Administración al
reconocer y entregar dinero adicional a los particulares; en todo caso, no puede
aceptarse la aplicación de la presunción de buena fe cuando se ha obtenido lucro
a través de una acción reprochable; sin embargo, para que el juez contencioso
ordene devolver sumas de dinero por parte de los particulares, prima el aspecto
subjetivo con el cual actuó el particular para recibir esos beneficios económicos.
An Unusual Case of Gallbladder Carcinoma with Pseudopancreatic cyst
Authors: Nahin Akhtar  , Mushtaq Huma , Ahmed Raza
Published: October 2019

Generally, carcinoma of the gallbladder is an extremely unusual neoplasm, however, high incidence rates have been reported in certain parts of the world. The role of certain factors such as genetic susceptibility, lifestyle and infections of gallbladder in causing carcinogenesis is still not clearly understood. Due to its early vague symptoms and lack of serosa in the gallbladder to slow its spread, gallbladder carcinoma typically presents at an advanced stage with a five-year survival rate of less than 5%. Pseudopancreatic cyst is an uncommon but not a rare complication of acute pancreatitis and injury to the pancreas. However, it rarely presents with carcinoma of gallbladder. We present here an unusual case of gallbladder carcinoma with pseudopancreatic cyst in a 58-year old male.

A INVENÇÃO E A REINVENÇÃO: FLUÊNCIA E CONFLUÊNCIA ENTRE MICHEL SERRES E PAULO FREIRE
Authors: De Sá Geraldo Mateus de Sá Mateus
Published: October 2019

Este texto, ainda que de forma breve, pretende aproximar Michel Serres e Paulo Freire. Neste sentido, entende-se que as ideias contidas em suas obras são possibilidades inovadoras de se pensar o mundo, o homem, a educação, a sociedade e o conhecimento. São também obras que instigam a invenção e a reinvenção de novas formas de ensinar e de aprender, especialmente no contexto contemporâneo, em que os jovens e os educadores, ambientados em outra realidade, não mais vivem nem convivem no mundo de seus antepassados. Por isso, o pensamento de Michel Serres e de Paulo Freire sugere, à luz de uma abordagem crítica, novos caminhos e alternativas para uma educação voltada para a concretude do mundo e para o inacabamento do homem, cujo intuito primeiro é a humanização do homem arraigada no mundo e na relação com outros homens. Conceitos como invenção e reinvenção são assinaturas originais e dinâmicas da concepção pedagógica do ‘filósofo das narrativas’ e do ‘educador viajante do óbvio’, ambos concatenados com o mundo, o homem, a educação e a efetivação de uma nova pedagogia.

Esta pesquisa objetivou analisar as condições de trabalho dos professores de ensino fundamental das escolas estaduais da região central de Divinópolis-MG e verificar a relação destas com o estresse docente. Para obtenção dos dados foi utilizado um questionário para caracterizar as condições de trabalho e o Inventário de Sintomas de Estresse. Para verificar a relação entre as condições de trabalho e a presença de estresse, foi utilizado o teste ?2 (Chi-quadrado). Participaram do estudo 95 professores. Dentre as condições de trabalho analisadas, destacaram-se negativamente a inadequada infraestrutura das escolas, a violência contra os docentes e a insatisfação com a remuneração. Com relação ao estresse, foi constatado que 58% dos amostrados apresentavam algum nível de estresse, que mostrou-se significativamente associado ao fato do docente trabalhar em dois ou mais turnos e ter presenciado/sofrido violência na escola. Estes dados reforçam a importância da valorização do trabalho docente como forma de minimizar os impactos da função sobre a saúde deste trabalhador.

Gerencialismo e Performatividade na Gestão da Educação Brasileira
Authors: PARENTE Juliano Mota
Published: October 2019

The objective of this article is to identify the main elements that underpin managerialism and performativity in Brazilian educational management, instituting regulatory parameters and performance culture. The expansion of performativity in Brazilian education, based on financial rationality and productivity, introduces a new perspective in the educational process, legitimizing the competitiveness and standardization of education. The present work constitutes a theoretical essay that sought to systematize the main characteristics of managerialism and performativity and its consequences in the management of Brazilian education. The analysis of the theme allowed us to conclude that the performative flow that has been established in Brazilian education has modified the conception of education insofar as it demands from the teacher a high degree of productivity and accountability in the educational process.

Antimony deposition onto Au (111) and insertion of Mg
Authors: Lingxing Zan , Xing Da , Abd-El-Latif Abdelaziz , Baltruschat Helmut
Published: October 2019

Magnesium based secondary batteries have been regarded as a viable alternative compared to the immensely popular Li-ion systems owing to its high volumetric capacity. One of the largest challenges is the selection of Mg anode material since the insertion/extraction processes are kinetically slow because the large ionic radius and high charge density of Mg2+ compared with Li+.

We prepared very thin films of Sb by electrodeposition on an Au (111) substrate. Monolayer and multilayer deposition (up to 20 Monolayer) were characterized by cyclic voltammetry and STM (Scanning-Tunneling-Microscope). Monolayer deposition results in a characteristic row structure; the monolayer is commensurate in one dimension, but not in the other. The row structure is to some extent maintained after deposition of further layers. After dissolution of the multilayers of Sb the substrate is roughened on the atomic scale due to alloy formation, as demonstrated by CV and STM. Further multilayer deposition correspondingly leads to rough deposit with protrusion of up to 3 nm.

The cyclic voltammogram for Mg insertion/de-insertion from MgCl2/AlCl3/Tetraglyme (MACC/TG) electrolyte into/from Sb modified electrode shows a positive shift (400 mV) of the onset potential of Mg deposition compared to that at bare Au electrode. From the charge of Mg deposition, we find that the ratio of Mg to Sb is 1:1; and this somewhat less than expected for the Mg3Sb2 alloy.
Associations between Handgrip Strength and Vitamin 25(OH)D Levels in Geriatric Patients
Authors: Aksoy Meliha Kasapoğlu , Altan Lale , Karlıbel İlknur Aykurt
Published: October 2019

Introduction: Thirty percent of the muscle mass is lost between the third and eighth decades of life. Vitamin D may have different roles in different aspects of the muscle cell function.

Aim: To assess the correlation between vitamin 25(OH)D levels, handgrip strength (HGS), and finger pinch strength (FPS) in elderly.

Materials and methods: This was a clinical observational study. It included a total of 92 patients of 65 years and over with good general health status and 66 young healthy volunteers. They all underwent HGS and FPS measurements. Study groups were further stratified into those with a serum 25(OH)D levels higher than 30 ng/dl and those with lower than 30 ng/dl.

Results: When geriatric patients were divided into two groups based on 25(OH)D levels, no statistically significant intergroup differences were found in FPS (p>0.05) while statistically significant differences were found in HGS (p<0.05). The analysis of the correlations between HGS and 25(OH)D concentrations revealed a positive, statistically significant correlation between these two parameters at r= 0.330 (p<0.05).

Conclusions: This study demonstrated that serum vitamin 25(OH)D levels have an impact on HGS in both geriatric group and control group.
Megafire effects on spotted owls: elucidation of a growing threat and a response to Hanson et al. (2018)

Published: October 2019

The extent to which wildfire adversely affects spotted owls (Strix occidentalis) is a key consideration for ecosystem restoration efforts in seasonally dry forests of the western United States. Recently, Jones et al. (2016) demonstrated that the 2014 King Fire (a “megafire”) adversely affected a population of individually-marked California spotted owls (S. o. occidentalis) monitored as part of a long-term demographic study in the Sierra Nevada, California, USA because territory occupancy declined substantially at territories burned at high-severity and GPS-tagged spotted owls avoided large patches of high-severity fire. Hanson et al. (2018) attempted to reassess changes in territory occupancy of the Jones et al. (2016) study population and claimed that occupancy declined as a result of post-fire salvage logging not fire per se and suggested that the avoidance of GPS-marked owls from areas that burned at high-severity was due to post-fire logging rather than a response to high-severity fire. Here, we demonstrate that Hanson et al. (2018) used erroneous data, inadequate statistical analyses and faulty inferences to reach their conclusion that the King Fire did not affect spotted owls and, more broadly, that large, high-severity fires do not pose risks to spotted owls in western North American dry forest ecosystems. We also provide further evidence indicating that the King Fire exerted a clear and significant negative effect on our marked study population of spotted owls. Collectively, the additional evidence presented here and in Jones et al. (2016) suggests that large, high-severity fires can pose a threat to spotted owls and that restoration of natural low- to mixed-severity frequent fire regimes would likely benefit both old-forest species and dry forest ecosystems in this era of climate change. Meeting these dual objectives of species conservation and forest restoration will be complex but it is made more challenging by faulty science that does not acknowledge the full range of wildfire effects on spotted owls.
Aux sources du coaching et de ses morales (1930-2018)
Authors: Salman Scarlett
Published: October 2019

Le coaching en entreprise relève d’une perspective d’optimisation de soi, en liant performance et bien-être au travail. L’article propose de réinscrire ce dispositif dans une histoire longue des relations entre psychologie et management, saisie à partir de l’entre-deux-guerres et dans le contexte français. Le retour sur cette généalogie permet de dégager la spécificité des idéologies du coaching – d’une part, la « réalisation de soi » et la figure de « l’entrepreneur de soi » ; d’autre part, le « savoir-être » et la figure du « manager-coach » ou du « leader » – et de les resituer au sein des transformations du capitalisme.
Optimiser sa beauté, s’approprier esthétiquement son corps : succès et échecs au sein des élections de Miss
Authors: Couvry Camille , Braizaz Marion
Published: October 2019

Certaines personnes, dans toutes les catégories sociales, d’âge et de sexe, prêtent un sens positif, en termes de bien-être, aux pratiques esthétiques qu’elles mettent en œuvre. À partir d’une enquête qualitative conduite dans un espace où l’optimisation esthétique est instituée et est au cœur des activités, les élections de Miss en France, cet article vise à expliciter dans quelle mesure les pratiques de beauté constituent des techniques exemplaires de l’optimisation du bien-être, et plus largement de soi. Après avoir développé les modalités de l’optimisation esthétique dans les élections de Miss, nous nous intéresserons à deux sens du bien-être – subjectif et interactionnel – associés à l’optimisation esthétique de soi. Ensuite, nous mettrons en évidence les situations dans lesquelles la gestion de l’apparence se heurte à certaines limites, voire échoue à être vectrice de satisfaction ; l’optimisation de soi par l’esthétique restant, dans de nombreuses configurations sociales, une entreprise stigmatisante.
(Micro-) “Psychedelic” Experiences: from the 1960s creativity at the workplace to the 21st Century neuro-newspeak
Authors: Aronov Milana
Published: October 2019

Depuis les années 1990, la réévaluation des hallucinogènes, ou psychédéliques , comme catégorie de substances a généré des hypothèses de recherche sur l’utilité de « micro-doses » de celles-ci pour l’amélioration d’activités de la vie quotidienne. Si dans la recherche en management ces substances ont été perçues par certains comme un outil pour l’étude de la « créativité », le « microdosage » a aussi suscité la critique. À partir d’un corpus documentaire et d’entretiens, cet article s’intéresse aux façons dont la notion « d’amélioration », telle que liée au terme psychédélique , a émergé dans la Californie des années 1960, et à son déploiement dans les pratiques et discours actuels autour du « microdosage ».
Extension chiffrée du domaine du perfectionnement ? La place des technologies de quantification du soi dans les projets d’auto-optimisation des individus
Authors: Dagiral Éric
Published: October 2019

Cet article analyse les usages contemporains des technologies numériques de quantification lorsqu’elles sont employées dans le but d’optimiser différentes facettes de l’existence des individus. Appuyé sur une enquête des pratiques émergentes du Quantified Self d’une vingtaine de cadres américains et français, il étudie la place des chiffres et la mesure des activités parmi les projets d’auto-optimisation du soi. Il montre que ce travail de perfectionnement, parce qu’il s’efforce d’articuler des objectifs et des valeurs, rend délicate et souvent épuisante l’entreprise de perfectionnement par les chiffres – ces derniers occupant en conséquence une place limitée. Il met également en évidence combien ces pratiques, à l’interface de la vie professionnelle, familiale, amicale et personnelle, attestent de l’intensification du souci de soi et des pratiques d’auto-contrôle des cadres en matière d’hygiène, de santé et de « bien-être », lesquels se positionnent en garants de ce nouvel équilibre général.
Sensibilités alimentaires et séditions corporelles : de la vulnérabilité à un idéal moral ?
Authors: Wolff Virginie
Published: October 2019

À partir d’entretiens et d’observations ethnographiques réalisés avec des personnes qui évitent les aliments contenant du gluten, cet article propose de montrer comment la sensibilité alimentaire n’est pas un donné, mais l’issue d’un parcours d’optimisation de soi, qui fait de la vulnérabilité du corps, une ressource menant à la connaissance et à l’amélioration de soi. À partir d’un décodage fin de la sensation corporelle, les personnes adoptant un régime « sans » déclarent mettre en œuvre une nouvelle éthique et un sens pratique ; la sensibilité alimentaire devenant également un langage exprimant une relation conflictuelle avec le modèle de société contemporain.
Garder le cap. Corps, masculinité et pratiques alimentaires à « l’âge critique »
Authors: Diasio Nicoletta , Fidolini Vulca
Published: October 2019

Les recherches sur les masculinités font l’objet d’un intérêt grandissant depuis deux décennies. Elles ont toutefois peu interrogé le rapport des hommes adultes à leur corps, à leur santé et aux pratiques alimentaires. À travers une ethnographie des choix alimentaires d’hommes ayant entre 40 et 60 ans rencontrés en France et en Italie, le texte essaie de répondre aux questions suivantes : comment s’articulent constructions des âges, pratiques alimentaires et stratégies d’optimisation de soi ? Et, en particulier, comment cet agencement aboutit-il à des formes de masculinité renforcées ou renouvelées ? L’article présente les stratégies d’amélioration de soi mises en œuvre par nos interlocuteurs à travers l’adoption de différents régimes (carnivore, végétarien, végan, cas de jeûne) et essaie de dégager les figures de la masculinité qui émergent de ces pratiques alimentaires et des discours utilisés pour les justifier.
Le véganisme : l’abolition par la nutrition. Comment se complémenter en vitamine B 12
Authors: Mouret Sébastien
Published: October 2019

Cet article montre comment l’invention et les pratiques d’un régime végane, fondé sur une alimentation végétalienne, s’appuient sur une technologie alimentaire : la complémentation en vitamine B 12 . D’un côté, celle-ci consacre une rupture anthropologique avec l’incorporation d’animaux, pour œuvrer à la réparation du monde vivant et contribuer ainsi à l’amélioration morale des hommes. De l’autre, elle permet de vaincre les maux du corps humain liés à ce régime, donc de taire sa résistance au véganisme. Devenir végane implique une forme d’optimisation de soi qui a trait autant avec l’ascétisme, qu’avec l’ human enhancement.
« Libérées, délivrées ! » : stérilisées et sans enfant
Authors: Tillich Emma
Published: October 2019

Cet article se penche sur la pratique de la stérilisation chez des femmes childfree (sans enfant par choix). La stérilisation constitue la contraception optimale à bien des aspects pour les enquêtées. Elle est à penser dans le contexte d’une culture subversive de l’optimisation de soi qui impose une nouvelle hiérarchie des valeurs en plaçant la procréation au bas de l’échelle de la réalisation personnelle et l’auto-contrôle reproductif au sommet. Quasiment uniquement féminine, la pratique est donc aussi une forme genrée d’amélioration de soi.
« Ce n’étaient peut-être pas des canards ». L’anthropologue à l’épreuve de l’intersubjectivité
Authors: Ariel de Vidas Anath
Published: October 2019

Ce texte concerne les retombées sociales et culturelles d’un accident qui a coûté la vie à un jeune homme de 18 ans du village indien nahua de La Esperanza au nord-est du Mexique. L’anthropologue, endeuillée par la mort de son filleul devient ainsi partie prenante de cette société qu’elle étudie. Entre affect et raison elle tente de parer à l’inconcevable en rapportant un récit ethnographique dense de rituels, mécanismes sociaux et émotions, celles de ses interlocuteurs et les siennes. Ces métadonnées restituent finalement le terreau sur lequel se construit le savoir anthropologique sur la société étudiée.
Philippe II et les anciens Pays-Bas (1555-1598). Les limites d’un gouvernement à distance dans un empire global
Authors: Soen Violet
Published: October 2019

La relation du roi d’Espagne Philippe II avec ses territoires patrimoniaux aux anciens Pays-Bas a fait couler beaucoup d’encre. Selon la « légende noire » largement diffusée depuis le xvi e  siècle, le souverain semble tromper et mépriser ses terres héréditaires, mais selon une « légende rose » récente et révisionniste, il paraît apprécier les Pays-Bas, en particulier pour leur art, leur architecture et leur horticulture. Cet article a par conséquent pour ambition d’envisager sous un nouvel angle le gouvernement de Philippe II dans les Dix-Sept Provinces dans son contexte propre et en se fondant sur l’ensemble des apports de l’historiographie des deux dernières décennies. Il envisage successivement la stratégie de Philippe aux Pays-Bas dans le cadre des logiques dynastiques au sein de la famille des Habsbourg et d’une monarchie composite, l’importance de la cour et de la bureaucratie dans le maintien de liens de loyauté entre Bruxelles et Madrid et enfin l’importance des divisions religieuses, d’ampleur européenne, dans les conflits des anciens Pays-Bas. Une attention toute particulière a été accordée à la manière dont le roi a fait usage des réseaux de patronage et de communication pour intégrer ces territoires à sa monarchie polycentrique et à l’échec partiel qu’il a rencontré dans ce domaine à l’issue de son règne.
La marine de guerre française et les grandes épidémies en Méditerranée. Quarantaines, réseau hospitalier et proto-impérialisme sanitaire (années 1820-années 1830)
Authors: Pouget Benoît
Published: October 2019

Dans les années 1820 et 1830, la fièvre jaune et le cholera s’associent à la peste pour renouveler les risques épidémiques qui pèsent sur l’espace méditerranéen. En proposant une réflexion à partir du « choc de circulations » induit par la confrontation qui met aux prises la marine de guerre française et ces grandes épidémies en Méditerranée, il s’agit bien de voir comment la Marine s’adapte au défi épidémique et s’affirme comme un acteur important d’un proto-impérialisme sanitaire français en amont des grandes conférences sanitaires internationales du second xix e  siècle. À la défense maritime passive héritée de pratiques multiséculaires de quarantaines, une approche plus dynamique aboutit à la formalisation d’un réseau hospitalier français (et au-delà européen) de points d’appuis sanitaires maritimes. Ce sont autant de positions géostratégiques essentielles alors que la France s’emploie à construire, exercer et soutenir ses ambitions méditerranéennes.
Radiographie du mouvement anarchiste français de 1881 à 1894 : éléments pour servir une réflexion sur l’existence d’une internationale noire à la fin du XIX e siècle
Authors: Bouhey Vivien
Published: October 2019

Alors que les historiens n’hésitent pas aujourd’hui à donner des définitions moins restrictives de ce qu’est une internationale, Vivien Bouhey prolonge ici la réflexion menée dans sa thèse sur le fonctionnement du mouvement anarchiste en montrant que celui-ci serait une internationale faible. Son article s’inscrit dans le cadre d’un débat sur l’existence d’une internationale anarchiste ouvert en 2009 par Marianne Enckell dans Le Mouvement Social 1 .
