L’affaire du lait contaminé
Authors: Keck Frédéric
Published: June 2013

L e scandale produit par la révélation de l’usage de mélamine dans le lait en poudre, causant des troubles du système rénal, est une des plus grandes crises sanitaires de la Chine contemporaine. Depuis l’épidémie de SRAS en 2003, le gouvernement chinois est particulièrement mobilisé sur les questions de santé publique (1) . Celles ci donnent l’occasion à la population d’exprimer des critiques légitimes, interdites dans le cadre strictement politique, en posant la question de la responsabilité au plus haut niveau possible. Comment le gouvernement chinois a-t-il pu laisser un tel agent toxique contaminer le circuit commercial du lait ? Les médias étrangers se sont emparés de l’affaire pour brocarder un peu plus le label « Made in China » , déjà mis à mal par le scandale touchant les jouets Mattel. Ce n’est plus le gouvernement mais toute une culture chinoise de la fraude qui est alors critiquée au niveau international. Dans sa structure, son déroulement et l’ampleur de ses conséquences possibles, cette crise est très analogue à «l’affaire du sang contaminé » , qui a secoué le gouvernement socialiste français au début des années 1990 et conduit à un des plus retentissants procès de la Ve République (2). Or, on sait que des phénomènes comparables de contamination du circuit de transfusion du sang ont eu lieu dans la province du Henan, sans susciter une affaire menant à l’accusation de responsables politiques (3). La question doit être alors posée à un autre niveau que celui sur lequel se situe immédiatement l’émotion publique. Comment comprendre qu’une industrie apparemment mineure en Chine – la fabrication de produits laitiers – puisse susciter une crise sanitaire que les révélations sur le sang contaminé en Chine n’ont pas réussi à provoquer ? L’analyse qui suit s’appuie sur la lecture des articles concernant ce scandale, entre sa révélation en septembre 2008 et le procès des responsables de Sanlu en janvier 2009, ainsi que sur une hypothèse anthropologique mise à l’épreuve lors d’autres crises sanitaires. La source principale est le South China Morning Post (SCMP), suivi pendant toute la période et complété par quelques sondages dans les médias chinois et français. On distinguera trois étapes : la révélation du scandale, l’enquête sur la sécurité sanitaire des aliments, la difficile résolution judiciaire.
Photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides
Authors: Kobiki Yohsuke , Kawaguchi Shin-ichi , Ohe Takashi , Ogawa Akiya
Published: June 2013

A novel method of photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides has been developed. Although the arylation reactions with triarylbismuthines are usually catalyzed by transition-metal complexes, the present arylation of diaryl diselenides with triarylbismuthines proceeds upon photoirradiation in the absence of transition-metal catalysts. A variety of unsymmetrical diaryl selenides can be conveniently prepared by using this arylation method.
Remaniements pulsionnels autour de la grossesse
Authors: Stern Sarah , Dupeyron Louise
Published: June 2013

La grossesse est l’occasion de remaniements pulsionnels, quelle incidence cela a-t-il sur le Surmoi ? Si Freud a toujours considéré le Surmoi féminin immature, plus faible que chez le garçon, la clinique nous montre parfois au contraire des jeunes femmes en proie à des conflits d’une très vive intensité. À partir d’un cas clinique, les auteurs interrogent l’impact de la grossesse sur l’émergence d’un Surmoi féroce, sur la nature de ses impératifs, et ses liens avec l’œdipe. Enfin, on peut se demander ce qu’induisent les débordements pulsionnels contemporains de l’arrivée du bébé dans les institutions du champ de la périnatalité.
Parentalité coupable ou hypercoupable ? Telle est la question !
Authors: Apter Gisèle , Palacio Espasa Francisco
Published: June 2013

La naissance d’un enfant vient modifier la position des parents dans la lignée des générations. La mise en route des processus inhérents à la parentalité contient, en germe, une conflictualité intrapsychique active. Le jeu des identifications des parents avec leurs propres imagos parentales détermineront les possibilités de l’abord de leur conflictualité interne. Les auteurs souhaitent proposer une relecture de l’élément central qu’est la position dépressive comme étape essentielle dans la construction psychique. Il s’agira d’analyser la détresse infantile du parent et/ou du patient afin de ne pas renforcer son sentiment de culpabilité, et d’empêcher les projections et les identifications à un Surmoi dévastateur et/ou castrateur. Les trois scénarios névrotique, masochique et narcissique de la parentalité permettent de repérer la nature des mécanismes identificatoires, afin de mieux les aborder et de les dénouer si les mécanismes sont névrotiques, de les éclaircir et de les apaiser s’ils sont masochiques, et de les limiter en les contenant s’ils sont narcissiques.
Troubles dans l'écriture
Authors: Melot Michel
Published: June 2013

L’histoire de l’écriture n’est plus ce long fleuve tranquille qui prenait sa source à Sumer pour aller se jeter dans l’alphabet, loin du continent des idéogrammes chinois. Les écritures de l’image et du son, celles des calculs et des programmations, circulent à vive allure au large de la langue. L’écriture mécanique déjà s’émancipait du scribe ; mais qu’advient-il de l’écrivain, à l’ère des codes numériques que seuls savent lire les robots ?

Una introduccion al renacimiento de la taxonomia
Authors: Faugère Elsa , Arpin Isabelle
Published: June 2013

El texto muestra como la disciplina de la taxonomía o también llamada sistemática, a través de los diferentes enfoques y técnicas utilizadas (entre otros el barcoding) para la exploración y documentación de nuevas especies, se vuelca en una lucha por mantenerse viva en un contexto que no está influido por los mismos límites de la biodiversidad a estudiar, si no por la organización misma de la disciplina, como es el minimizar la ausencia de especialistas y afrontar las restricciones geopolíticas y de propiedad intelectual (como se da en las expediciones de países del sur). Los autores muestran la necesidad de incluir en los estudios de biodiversidad a investigadores de disciplinas como las ciencias sociales para dar una transformación y apertura de campos en las investigaciones, a través de los resultados obtenidos en las diferentes expediciones naturalistas. El texto es claro al detallar la problemática surgida en las dificultades de forjar relaciones de confianza entre los sistemáticos y los investigadores en ciencias sociales. El deterioro y el poco intercambio de información y técnicas, amenaza con perder la lucha por sacar la taxonomía del contexto académico y dar el tan esperado renacimiento a la disciplina.
Platon à l'époque victorienne contre l'idée de système
Authors: Schofield Malcolm
Published: June 2013

On considère généralement que les deux grands platoniciens de l’ère victorienne – George Grote et Benjamin Jowett – ont défendu des perspectives opposées sur Platon. Tout ce que leurs lectures respectives ont de commun n’est pas moins important : une herméneutique « atomiste », en réaction contre toutes les tentatives de systématisation des Dialogues , et un mélange d’attention scrupuleuse portée à l’historicité des textes et d’insistance sur l’idée que donner sa place à Platon dans l’histoire de la philosophie et dans « l’échelle du progrès humain » fait partie de l’obligation qui incombe à l’historien
De l'homme démocratique à l'animal grégaire
Authors: Dixsaut Monique
Published: June 2013

Ce n’est pas leur critique du régime démocratique qui rapproche Platon et Nietzsche mais un même diagnostic : la démocratie est l’avant-dernière étape d’une déchéance dont la dernière est la tyrannie. Un tel diagnostic ne se comprend qu’à la condition de rejeter les interprétations déterministes du livre VIII de la République et de faire appel aux concepts nietzschéens de généalogie, provenance ( Herkunft ), type. C’est ce même schème qui explique chez Platon le passage d’un extrême à l’autre – de l’homme démocratique au tyran – et qui chez Nietzsche annonce le destin de l’Européen moderne : son nihilisme passif engendrera un animal grégaire, un « dernier homme ».
Ivan Grafenauer. First Chair of the SAZU Institute of Slovenian Ethnology and Researcher of Literary Folklore
Authors: Stanonik Marija
Published: June 2013

Razprava o Ivanu Grafenauerju na kratko predstavi njegovo življenjsko pot. Izkazal se je že kot študent slovanske in germanske filologije, vendar kljub odlični strokovni pripravljenosti ni postal visokošolski učitelj. Zanj osebno je nadomestilo za to izgubljeno možnost pomenila priložnost, da je postal prvi predstojnik novoustanovljenega Inštituta za slovensko narodopisje pri Slovenski akademiji znanosti in umetnosti. Sledijo poglavja s povzetki in komentarji o njegovem delu, predvsem glede na slovstveno folkloristiko. Zanjo je zaslužen predvsem s sintetičnimi članki (npr. v Narodopisje Slovencev II) in nekaterimi temeljitimi razpravami o »narodni pesmi«, medtem ko »kulturno-historična metoda«, ki jo je s takim zanosom prakticiral, že zdavnaj nima več prave veljave.
***
This discussion briefly recounts the life of Ivan Grafenauer. He stood out as a university student of Slavic and German philology; however, despite his excellent training he did not pursue a career in this field. Grafenauer instead substituted this lost professional option with the opportunity to become the first head of the newly established Institute for Slovenian Ethnology at the Slovenian Academy of Sciences and Arts. The following chapters are commentaries of his life work, focused primarily on literary folklore. The themes set apart for discussion include this synthetic works (for example The Ethnography of Slovenians II) and certain fine-grained analyses of folk songs. However, the cultural-historical method, which he implemented with such enthusiasm, is no longer held to be professionally valid.
El amianto en la edificación: variedades y riesgos asociados a las labores de deconstrucción
Authors: Mateo M. , Pérez-Carramiñana C. , Chinchón S.
Published: June 2013

El amianto es un producto mineral que fue ampliamente utilizado como material de construcción durante la segunda mitad del siglo XX. El descubrimiento de las enfermedades producidas por la inhalación de sus fibras impulsaron la creación de normativas para proteger a los trabajadores y prohibir su comercialización.

Este artículo describe los tipos mineralógicos más importantes desde el punto de vista de la construcción, los principales efectos sobre la salud derivados de su exposición, e identifica su presencia en materiales de construcción y su riesgo potencial. Se revisa el proceso de diagnóstico de amianto en edificios existentes, la toma de muestras y la determinación de la concentración de fibras de amianto. Estos datos permiten conocer el grado de friabilidad del material y determinar el tipo de actuación a realizar. Asimismo, se revisa la situación actual de la gestión de residuos de amianto.
La participación en asociaciones de los inmigrantes africanos. Vías de interpretación del distanciamiento asociativo
Authors: Lacomba Vázquez Joan , Giner Monfort Jordi
Published: June 2013

Este artículo se adentra en las razones de la no-participación de la población africana en las asociaciones de inmigrantes. Para ello se utilizan entrevistas semidirigidas realizadas a personas que deciden de manera consciente no participar en las asociaciones y a entidades que trabajan con inmigrantes, en el contexto de un proyecto de investigación mucho más amplio y de carácter multilocal centrado en Cataluña, la Comunidad Valenciana y Navarra. El desapego asociativo, observado a través de las entrevistas, se interpreta como un distanciamiento más o menos voluntario, basado en la ausencia de información, la falta de tiempo, el desencanto, el activismo unipersonal, la espera pasiva o la condición de población únicamente usuaria, pero también en factores de mayor calado como la cultura política o el cuestionamiento de los liderazgos asociativos.
Liderazgo femenino. Un análisis de las diferencias de género en la formación y desarrollo de asociaciones de inmigrantes africanos
Authors: Molina Luque Fidel , Samper Rasero Luis , Mayoral Arque Dolors
Published: June 2013

En el presente estudio se describen, analizan y comparan las manifestaciones del liderazgo femenino en las asociaciones de inmigrantes africanos: sus objetivos de trabajo, temáticas y formas, organización e institucionalización. Para ello se analizan en profundidad diez historias de vida, partiendo de la hipótesis de la existencia de una clara diferenciación de objetivos entre las asociaciones de hombres y mujeres africanos derivados de la desigualdad básica de las posiciones sociales entre hombres y mujeres, y muy especialmente, de las culturas de género. Los resultados obtenidos sugieren que existen mujeres inmigrantes “fuertes” (ni sumisas ni ignorantes) con capacidad de liderazgo en la asociación, pero no por unas supuestas especificidades “femeninas” sino por un proceso de aprendizaje temprano (adolescente), éxito educativo y un origen social relativamente elevado que forjan una cierta rebeldía y la asunción de una autoridad explícita. De cualquier modo, no se observan diferencias relevantes entre el liderazgo femenino y el liderazgo masculino, ya que en ambos casos se da un cierto “carisma”, la existencia de unas dotes personales que se desarrollan desde la interacción en situaciones sociales concretas.

Authors: Liu Yan Fang , Mao Ming Chong , Xu Xiang Yang , Shi Gang
Published: June 2013

Solenoid valve is complex heterogeneous system involving multi-physics coupling of mechanics, electronics, magnetics, thermotics, etc, whose reliability and life depends largely on the heat generated during the operation. A multi-physics coupled thermo-mechanics model of a hydraulic proportional solenoid valve used in an automatic transmission was built up with the finite element method (FEM), the temperature and thermal deformation of the solenoid valve with different currents under two operating environments was analyzed. The calculated results show that the operating environment and current are important factors leading to thermal failure of solenoid valves. The model has high accuracy because of considering the multi-physics coupling control characteristics of mechanics, electronics, magnetics, thermotics, etc, and so can be used for the reliability design of solenoid valves.

Published: June 2013

In this paper we propose a powerful visual event pattern learning method to address the issue of high-level video understanding. We first model the deformable temporal structure of the action event in videos by a temporal composition of several primitive motions. Moreover, we describe each action class by multiple temporal models to deal with the significant intra-class variability. We implement a multiple instance learning method to train the models in the weakly supervised setting. We have conducted experiments on three major benchmarks. The results are comparative to the state-of-the-arts.

An Improved Color Image Enhancement Algorithm Based on 3-D Color Histogram Equalization
Authors: Song Yu Ting , Ji Xiu Hua , Zhao Shi Lin
Published: June 2013

This paper proposes an improved color image enhancement algorithm based on 3-D color histogram equalization algorithm. When the existed 3-D color histogram equalization algorithms in the literatures are applied in processing dim color images, the processed color images often turn pale due to the decrease of color-saturations and have false contours due to gray-scale merging phenomenon in the histogram equalization algorithm. In this paper, the proposed algorithm can make more pixels of the processed color images keep their color-saturations and reduce the gray-scale merging with Logarithmic histogram equalization algorithm. Test results with dim color images present a better effect of image enhancement.

The way of kernel function has been widely applied in machine learning field, such as artificial neural network and support vector machine, for avoiding dimensional disaster of feature space and improving performance of learning machine effectively. The selection of kernel function and construction of new kernel are the core problems, which have a direct relation with the performance of classification, and the research of this field is not enough. In this paper support vector machine (SVM) was used as an example, and the performance of common kernel functions was evaluated through observing and computing the features of kernel matrix. Base on this, a new mixed kernel function was gotten by optimization of kernel functions, and the experimental data proved that the performance of SVM was improved by the mixed kernel function. If the weighting coefficient was selected properly, the correct rate could even reach to 100%. What’s more, not only a method to construct a new learning machine was given, but also a reference for selecting kernel function was given.

Authors: Naushad Ali M.M. , Abdullah-Al-Wadud M. , Lee Seok Lyong
Published: June 2013

Moving human detection and tracking are challenging tasks in computer vision. Human motion is usually non-linear and non-Gaussian, and thus many common algorithms are not appropriate for tracking. In this paper we propose a robust tracking algorithm based on particle filter. Multiple moving human in a video sequence are detected using frame difference and morphological operation. Then feature points of every person are extracted using a Harris Corner detection algorithm. Finally, Histogram of Oriented Gradient (HOG) is calculated for each feature point and feature points of the corresponding person are tracked using particle filter. Experimental results demonstrate that our method is efficient to improve the performance of tracking.

Authors: Zhao Jie , Yi Fa Ling , Huang Zhan Peng
Published: June 2013

In order to overcome the shortcomings that GVF model is susceptible to structures with slender topology, an improved watershed algorithm is proposed to determine initial contour of GVF Snake model. The organs in medical CT images often were irregular and had deep boundary concavities, and CT serial images were up to hundreds pieces. Firstly, in a CT image the improved watershed algorithm grows an organ from a seed block by the principle of the similarity between gray scale and texture, then using its edge as the start contour of the adjacent CT sequence, with GVF algorithm segment the organ from a sequence of images, the process is repeated until get all slices of the entire abdomen. Experiment results which are the basic of 3-D reconstruction and cancer detection show that the new contour initialization algorithm can obtain segmentation result efficiently, accurately and cost less time.

A Theoretical Approach of the Time Cycle Optimisation Based Control of a Mechatronics Line Served by Mobile Robot
Authors: Minca Eugenia
Published: June 2013

In this paper a theoretical approach of the generalized hybrid model and time cycle optimization of a mechatronics line served by mobile robot with manipulator is presented. Thus, the considered global model is a hybrid one as it is based on the dynamics of discrete and continuous components which interact on a basic level. The generalized Synchronized Hybrid Petri Nets (SHPN) model describes this hybrid system with N degree of repetitive tasks. The advantage of this generalized approach consists in the optimization of the process parameters. Consequently, a time cycle optimization which is based on the minimization of temporal duration events is proposed. The proposal is exemplified by the assembly/disassembly process of a mechatronics line (A/DML), served by a wheeled mobile robot (WMR) equipped with a robotic manipulator (RM).

Authors: Yan Lu Tao , Yang Zhi Peng , Li Hong
Published: June 2013

The dynamic model of the reaction mass system in the large-scale vibration test system is set up, and the crossover frequencies are calculated in order to determine the operation capability and the interval between reaction mass and foundation. On the basis of the finite element method (FEM) analysis and theory of analysis mechanics, the dynamic response of the reaction mass is studied. The results show that the maximum amplitude of the dynamical system is obtained at the natural frequency of the system. The results of theoretical and FEM calculations indicate that the maximum displacements responses are all much lower than the design of the interval, which means the design is satisfied and reasonable. This method can calculate the operation capability of the reaction mass effectively and can be used for vibration test system design and optimization.

Published: June 2013

In order to increase the reliability and efficiency of the kineto-static analysis of complex multibody systems, the corresponding vector bond graph procedure is proposed. By the kinematic constraint condition, spatial multibody systems can be modeled by vector bond graph. For the algebraic difficulties brought by differential causality in system automatic kineto-static analysis, the effective decoupling method is proposed, thus the differential causalities in system vector bond graph model can be eliminated. In the case of considering EJS, the unified formulae of driving moment and constraint forces at joints are derived based on vector bond graph, which are easily derived on a computer in a complete form and very suitable for spatial multibody systems. As a result, the automatic kineto-static analysis of spatial multibody system on a computer is realized, its validity is illustrated by the spatial multibody system with three degrees of freedom.

Published: June 2013

The dynamic models of the infinite cylindrical shell with integrated piezoelectric actuator are derived firstly in this paper, then, the total input power flow is calculated and expressed as the Hermitian quadratic form to act as the objective function to implement the control. The optimum set of secondary force is obtained by using feed-forward quadratic optimal theory, and the total input power flow with control was calculated for different locations of the actuator. The results show that different axial and circumferential locations will induce different influences on the control effect, and the results are greatly related to the vibration type and the circumferential mode.

Published: June 2013

Independent components analysis (ICA) with constraint of seismic wavelet estimated from bispectrum of seismic traces is combined with short time Fourier transforms (STFT) to improve the traditional frequency domain seismic deconvolution. Neglecting noise, the seismic record is changed from time domain to frequency domain with STFT in order to transform the common seismic model to the basic ICA model. By applying FastICA algorithm with constraint of seismic wavelet estimated from bispectrum of seismic traces, reflectivity series and the seismic wavelet can be produced in frequency domain and changed back to the time domain subsequently. The model and real seismic data numerical examples all show the algorithm valid.
