  1. Quis custodiet ipsos custodies: who watches the watchmen?

    Should this be said again? No cell is an island and in tissue-specificity and cancer, context is supreme. Decades ago, seminal recombination experiments illustrated the dominant role of mammary mesenchyme in directing epithelial development, and strongly suggested that the microenvironment plays a significant role also in the manifestation of carcinoma. More direct evidence for such functions came from a study demonstrating that an unadulterated microenvironment can suppress the malignant phenotype and re-direct tumor cells to give rise to normally functioning tissues and indeed healthy mice. One may wonder why such a stunning finding did not convince the scientific community to pay more attention to the role of context. The answers are complex, not the least of which is that concomitantly with this finding, the roles of oncogenes and mutations were being discovered. That excitement carried the day, specially because no one subsequently determined whether or not these mice generated from malignant cells contained tumorigenic mutations, and no new group reproduced the work. The following decade saw the discovery that even potent oncogenes could be ruled by context, and another couple of decades later it was shown that similar reprogramming of metastatic melanoma by an embryonic microenvironment was possible. There are many more examples which are not as clear cut, but are nevertheless compelling. The extensive literature of two-stage carcinogenesis, namely initiation and progression, indeed clearly indicates that 'initiation' and DNA damage alone are not sufficient to allow carcinogenesis. Implicit in these findings is: once a tumor or an oncogene, not always a tumor or an oncogene. A renewed focus on the tumor microenvironment as a therapeutic target has also led to the recognition that markers within the microenvironment could have predictive power. Two recently published reports identifying 'stromal signatures' in breast cancer patients prognostic for patient survival and predictive of response to chemotherapeutic treatment provide proof of this concept. In the current issue of The American Journal of Pathology, two independent studies identify a novel stromal marker, caveolin (Cav)-1, which predicts clinical outcome of breast cancer patients irrespective of its expression in tumor epithelium. Cav-1 is a scaffolding protein essential to the structure of caveolae, 'little caves' or invaginations in cellular plasma membranes. Cav-1 recruits and arranges lipids and proteins to these membrane sites to function in endocytosis and signal transduction. The observation that Cav-1 expression is attenuated in oncogenically transformed cells led to exploration of whether Cav-1 loss in mammary epithelium was causative. Although mechanistic data suggested that Cav-1 null mice exhibited aberrant epithelial growth, and that forcing Cav-1 expression in breast cancer cell lines inhibited growth and metastases in xenograft models, a clinical link proved elusive. However, MMTV-PyMT tumors transplanted into the fat pads of Cav-1 knockout mice displayed significantly enhanced growth (vs. wild-type mice), motivating investigation of whether stromal Cav-1 expression correlates with human breast cancer patient survival. This is precisely what Sloan et al. and Witkiewicz, Dasgupta, et al. demonstrate in this issue of AJP. Using tissue microarray data in conjunction with breast tumor sections and extensive patient survival data, Sloan et al. demonstrate that strong stromal Cav-1 expression is associated with smaller breast tumor size and grade, and is highly predictive of increased survival (Fig. 1). Patients with positive expression of stromal Cav-1 had a 91% ten year survival rate, vs. a 43% survival rate for patients lacking stromal Cav-1 expression. Importantly, there was no correlation between Cav-1 expression in the tumor epithelium and clinical outcome in either tissue arrays or tumor sections.

    Full Text Available International criminal law has been long focusing on providing criminal responsibility to perpetrators of international crimes and preventing their impunity, but it also has to provide fair trial at the same time. In connection to this an issue arises, whether the legality of the procedure has to be ensured by external supervision. That became especially relevant with the establishment of a permanent International Criminal Court (the ICC. This paper therefore tries to verify the hypothesis that the Rome Statute includes all the regular mechanisms for protection of the defendant’s rights, but the external supervision is still required. The paper firstly discussed the existing possibility of protection of the defendant’s rights in the ICC − means of invoking or sanctioning violations of these rights through legal remedies, criminal, civil and tort liability or inadmissibility of evidence. Second part of the paper includes thoughts on possibility of the ICC joining the existing universal, regional or national supervisory mechanisms.

    Full Text Available The main purpose of this exercise was to develop an improved model of ministerial and spiritual formation in the training of ministers in the Uniting Presbyterian Church in Southern Africa at the University of Pretoria. This is a perennial problem in many churches where there is a general dissatisfaction with the products, (i.e. ministers not only in terms of personal spirituality but in their inability to minister effectively in the many diverse situations to which they are called or appointed. The exercise of power becomes an issue in a vocation which is premised on servant ministry and so Juvenal’s quotation is apt as it is expressed as ‘Who can be trusted with authority/power?’.

Pour commencer, Méduse est une jeune fille qui se fait remarquer : séduite puis violée par Poséidon, elle se révèle fertile puisqu'elle accouche de faux jumeaux, le cheval Pégase et le géant Chrysaor. Une longue fable la transforme en terrible puissance. Pour simplifier, disons que le monstre est par deux fois tué : Persée assassine d'abord Méduse pour assurer la protection de sa mère, Danaé, importunée par le roi Polydectès. Ensuite, il délivre Andromède des liens méduséens qui la retiennent et, pour ce faire, tranche la tête de la Gorgone. La mer se teinte de sang, tandis que le vainqueur tient à l'écart l'épouvantail de Méduse, de peur que ne soient changés en statues de pierre ceux qui s'exposeraient à sa vue.

    A theoretical basis for the regulation of corporate security warning and resources was provided in order to reveal the laws behind the security state in mine production logistics. Considering complex mine production logistics system and the variable is difficult to acquire, a superior security status predicting model of mine production logistics system based on the improved particle swarm optimization and support vector machine (IPSO-SVM) is proposed in this paper. Firstly, through the linear adjustments of inertia weight and learning weights, the convergence speed and search accuracy are enhanced with the aim to deal with situations associated with the changeable complexity and the data acquisition difficulty. The improved particle swarm optimization (IPSO) is then introduced to resolve the problem of parameter settings in traditional support vector machines (SVM). At the same time, security status index system is built to determine the classification standards of safety status. The feasibility and effectiveness of this method is finally verified using the experimental results.

    Full Text Available The problem of portfolio optimization has always been a key concern for investors. This paper addresses a realistic portfolio optimization problem with floor, ceiling, and cardinality constraints. This problem is a mixed integer quadratic programming where traditional optimization methods fail to find the optimal solution, efficiently. The present paper develops a new hybrid approach based on an improved particle swarm optimization (PSO and a modified simulated annealing (SA methods to find the cardinality constrained efficient frontier. The proposed algorithm benefits simple and easy characteristics of PSO with an adaptation of inertia weights and constriction factor. In addition, incorporating an SA procedure into IPSO helps escaping from local optima and improves the precision of convergence. Computational results on benchmark problems with up to 225 assets signify that our proposed algorithm exceeds not only the standard PSO but also the other heuristic algorithms previously presented to solve the cardinality constrained portfolio problem.

    2015-01-01

    N-acetylquinovosamine (2-acetamido-2,6-di-deoxy-d-glucose, QuiNAc) is a relatively rare amino sugar residue found in glycans of few pathogenic gram-negative bacteria where it can play a role in infection. However, little is known about QuiNAc-related polysaccharides in gram-positive bacteria. In a routine screen for bacillus glycan grown at defined medium, it was surprising to identify a QuiNAc residue in polysaccharides isolated from this gram-positive bacterium. To gain insight into the biosynthesis of these glycans, we report the identification of an operon in Bacillus cereus ATCC 14579 that contains two genes encoding activities not previously described in gram-positive bacteria. One gene encodes a UDP-N-acetylglucosamine C4,6-dehydratase, (abbreviated Pdeg) that converts UDP-GlcNAc to UDP-4-keto-4,6-d-deoxy-GlcNAc (UDP-2-acetamido-2,6-dideoxy-α-d-xylo-4-hexulose); and the second encodes a UDP-4-reductase (abbr. Preq) that converts UDP-4-keto-4,6-d-deoxy-GlcNAc to UDP-N-acetyl-quinovosamine in the presence of NADPH. Biochemical studies established that the sequential Pdeg and Preq reaction product is UDP-d-QuiNAc as determined by mass spectrometry and one- and two-dimensional NMR experiments. Also, unambiguous evidence for the conversions of the dehydratase product, UDP-α-d-4-keto-4,6-deoxy-GlcNAc, to UDP-α-d-QuiNAc was obtained using real-time 1H-NMR spectroscopy and mass spectrometry. The two genes overlap by 4 nucleotides and similar operon organization and identical gene sequences were also identified in a few other Bacillus species suggesting they may have similar roles in the lifecycle of this class of bacteria important to human health. Our results provide new information about the ability of Bacilli to form UDP-QuiNAc and will provide insight to evaluate their role in the biology of Bacillus. PMID:26207987

The IPSO algorithm improves the standard PSO algorithm to perfect the convergence rate and the capability of global convergence and is used for the BP neural network learning algorithm for adaptive semi-active suspension control. Adaptive controller has a two-unit structure neural network. One is an input controller, which adjusts the value of semi-active suspension damping in accordance with the road input; and the other is a semi-active suspension identifier which is used for online identification. Through the adaptive control test of the semi-active suspension based on the semi-active suspension controller, results show that the controller based on the IPSO-BP algorithm obviously improves the comfort and ride quality of the car. The vertical acceleration of the car body reduces 21.73% compared with the PSO-BP semi-active suspension. This algorithm improves the vehicle

    Si un monde de matière rencontrait un monde d’antimatière, on assisterait à une conflagration d’une extrême violence ! L’antimatière apparaît dans la théorie quantique comme une matière « miroir » selon les transformations de l’espace et de la charge, ou selon celle du temps. Pourquoi la nature a-t-elle créé ce monde miroir du nôtre ? L’Univers contient-il autant de matière que d’antimatière ? Où donc est passée toute l’antimatière qui était présente au début de l’Univers et pourquoi en a-t-on perdu la trace ? Dans cet ouvrage, qui fait référence, Gabriel Chardin nous aide à approcher cette « matière qui remonte le temps » !

    Full Text Available Dans l’église de Nārgā Śellāsē, construite dans les années 1738-1750, une sculpture très inhabituelle montre un homme qui fume. Cette représentation est d’autant plus surprenante que nous pensons généralement que le fait de fumer était fortement condamné dans la société chrétienne, comme en témoignent les textes qui prolifèrent à la fin du xixe siècle. Mais les images et l’archéologie donnent des informations contradictoires sur cette pratique, ce qui nous conduit à reconsidérer l’histoire des textes. Du xvie au xxe siècle, fumer a été stigmatisé comme une activité païenne pour montrer du doigt l’étranger, et par conséquent, affirmer la domination de l’État chrétien sur la région du Choa méridional. Enfin, la position de la sculpture de Nārgā au sein de l’église, en relation avec la liturgie, montre que l’image du « roi arrogant » a été utilisée pour créer une représentation religieuse du mal.In the church of Nārgā Śellāsē, built in the years 1738-50, a very unusual sculpture depicts a man smoking. This representation is surprising for we generally think that smoking was highly condemned in the Christian society. It is however what texts from the end of the nineteenth century assert. However pictures and archaeology give contradictory information on that practice. It leads us to reconsider the history of written sources. From the sixteenth to the twentieth century, smoking was stigmatized as a pagan tradition in order to designate the “alien” and, thus, to assert the domination of the Christian State on the region of the Southern Choa. To come back to the carving of Nārgā, the position of the sculpture inside the church according to the liturgy confirms that the association of this image with the “arrogant king” was used to create a religious representation of evil.

    Full Text Available A inicios del siglo XXI, América Latina se ve gobernada en su mayor parte por gobiernos de izquierda. Varios autores han diferenciado entre una izquierda ‘pragmática’, por un lado, y una ‘populista’ por otro. Usando datos de las encuestas AmericasBarometer del 2012, indagamos sobre el perfil socio-demográfico de quién apoya a la izquierda ‘populista’ en cuatro naciones: Argentina, Bolivia, Ecuador y Venezuela. Mediante modelos de regresión logística, analizamos las probabilidades de expresar intención de voto por el candidato o partido del actual presidente de ciudadanos pertenecientes a distintos niveles de educación, riqueza, y otras variables socio-demográficas. Los resultados permiten concluir que no todos los gobiernos calificados como pertenecientes a la izquierda ‘populista’ latinoamericana reciben el apoyo del mismo tipo de individuos.

    Full Text Available Depuis 2009, la sole de soja ne cesse d’augmenter en Allemagne, surtout dans le sud du pays mais aussi à l’est et un peu partout dans les régions au climat propice. Un programme national a permis de créer les références nécessaires pour un conseil qualifié apporté aux agriculteurs via un réseau de développement. Ainsi toute une filière soja est déjà bien avancée dans le sud et en cours de mise en place dans le reste du pays, pour organiser la collecte auprès des producteurs et obtenir une offre groupée pour les transformateurs pour l’alimentation animale et humaine. Le soja allemand ne veut pas rivaliser avec le soja OGM ni pour instant avec le soja non-OGM des Amériques mais vise plutôt les filières courtes régionales et le marché bio qui est encore plus déficitaire en auto-approvisionnement que le conventionnel. Avec 10 000 ha en 2014, dont 25 % en bio, le soja en Allemagne est encore loin de la surface du maïs grain (2008–2014 autour de 500 000 ha. En pratique, 20 % de ces surfaces de maïs au climat a priori propice pourraient représenter le potentiel réel pour le soja en Allemagne, sous condition de prix garantissant une rentabilité suffisante par rapport aux autres grandes cultures. Pour les programmes non-OGM des grands distributeurs, il faut de toute façon une base de production élargie comme celle proposée par l’initiative Danube-Soja, qui dans une version Europe-Soja engloberait aussi la France. Avec le verdissement de la PAC et la montée du cours du Dollar par rapport à l’Euro, les perspectives pour une augmentation de la surface de production de soja en Allemagne et en Europe paraissent bonnes. Maintenant il faut travailler sur les débouchés pour garantir l’absorption de la production grandissante par les marchés et les consommateurs à tous les niveaux : régional, national et européen.

    Full Text Available Este artículo recoge información nacional e internacional relacionada con la industria de drogas ilícitas. Si bien la lista de drogas prohibidas es amplia, este trabajo solamente se concentra en tres de ellas: la heroína, la cocaína y la marihuana. De estos tres productos, la marihuana tiene multitud de usos, pero su empleo como fármaco no exige ningún proceso adicional que le agregue valor. La producción de las otras dos, estrictamente hablando, no se realiza en una industria de grandes proporciones; se trata de producción en pequeña escala, integrada por un archipiélago muy grande de productores, cuyo volumen y nivel de operaciones suma miles de millones de dólares. El artículo pone de relieve las leyes que prohíben este negocio, pero al mismo tiempo destaca su inoperancia. Además estudia los procesos de producción y de comercialización, las estrategias de penetración en los mercados, y aborda las implicaciones éticas y morales del negocio. El trabajo se concentra en el estudio de las consideraciones socioeconómicas de este negocio, ilustra con algunos ejemplos quiénes son los principales beneficiarios de este tráfico, y llama la atención para que se consideren salidas diferentes a la represión y se piense mejor en la eliminación de las condiciones que hacen posible que la enorme masa de valor agregado que genera el proletariado rural que cultiva y procesa estos productos no sea el incentivo para que los narcotraficantes se apropien de ella a través de la especulación clandestina y para que su magnitud se reduzca a expresiones controlables política y socialmente.

    Full Text Available Fruit d’une enquête ethnographique auprès des correspondants de la presse étrangère en Israël dans les années 2000, cet article analyse la façon dont les relations des journalistes avec les différents états et nations (y compris les leurs impliqués dans le conflit, affectent leur travail. Il montre comment les journalistes, en fonction de leurs appartenances nationales ou ethniques, sont sommés de prendre parti vis-à-vis de multiples acteurs, ce qui déstabilise la possibilité d’une couverture « neutre » ou « extérieure » acceptable par tous. Cette déstabilisation est analysée à quatre niveaux. 1. Le monde professionnel des journalistes est traversé par ce conflit qui est perçu comme très proche, « quasiment une affaire de politique intérieure », les divisions étant politiques mais aussi nationales, singulièrement entre journalistes américains et européens. 2. Les journalistes sont sommés par les deux parties au conflit, toutes deux très soucieuses de leur image, l’Etat d’Israël recourant aux brimades – ou à la force vis-à-vis des gens d’image palestiniens, les deux partis étant « assoiffés de médias » ; 3.

Transcurría el año 1950 cuando estudiaba medicina en la Universidad Javeriana en Bogotá. Una tarde casi noche, con el frío sabanero, conocí un personaje cuyo nombre era Arturo Morillo Quiñones, el cual generaría en mí un impacto a diferentes niveles: intelectuales, científicos y humanos, en especial por su manera de ser auténtica, veraz, cálida, con un amplio humor, leal, inteligente, real y brillante. Por aquellos años 1950 establecimos una relación de una profunda amistad. Así vinieron diferentes hechos de nuestras historias personales y el conocimiento de la vida familiar, así como nuestras experiencias. Arturo relataba una serie de reminiscencias vividas de niño por allá en la región del Sinú, el Magdalena, y toda la región llamada de la “Costa Caribe”. Las narraciones que él hacía tenían un tinte de fascinación y despertaban al niño que todos guardamos, y que le seduce esa clase de historias, las cuales oscilaban entre la realidad y la fantasía, lo absurdo y lo lógico, lo primitivo imaginario de sueños despiertos a la realidad, además de una multiplicidad de creencias supersticiones dirigidas por el pensamiento mágico. Personalmente no cesaba de preguntar sobre detalles de los contenidos de las narraciones. Aquí consigno, cómo en los años 1967 volví a leer en textos novelescos estos mismos relatos de Arturo Morillo; ahora escritos por un genio Nobel, Gabriel García Márquez. El doctor Arturo Morillo Quiñones, académico y neurocientífico acabó sus estudios de medicina en 1951 y se graduó en 1954 en la misma Universidad Javeriana; realizó su postgrado en electroencefalografía y neurofisiología en National Institutes of Health, Bethesda, Maryland.

    To evaluate the impact of triaging women at risk of spontaneous preterm birth (sPTB) using the QUiPP App, which incorporates a predictive model combining history of sPTB, gestational age and quantitative measurements of fetal fibronectin, compared with a treat-all policy (advocated by the UK National Institute for Health and Care Excellence) among women with threatened preterm labor before 30 weeks' gestation. Prospectively collected data of pregnant women presenting with symptoms of preterm labor (abdominal pain or tightening) at 24-34 weeks' gestation were retrieved from the research databases of the EQUIPP and PETRA studies for subanalysis. Each episode of threatened preterm labor was retrospectively assigned a risk for sPTB within 7 days using the QUiPP App. A primary outcome of delivery within 7 days was used to model the performance accuracy of the QUiPP App compared with a treat-all policy. Using a 5% risk of delivery within 7 days according to the QUiPP App as the threshold for intervention, 9/9 women who presented with threatened preterm labor preterm labor would have been missed, as no woman who was assigned a risk of preterm labor, the QUiPP App can accurately guide management at risk thresholds for sPTB of 1%, 5% and 10%, allowing outpatient management in the vast majority of cases. A treat-all approach would not have avoided admission for any woman, and would have exposed 188 mothers and their babies to unnecessary hospitalization and steroid administration and increased the burden on network and transport services owing to unnecessary in-utero transfers. Prediction of sPTB should be performed before 30 weeks to determine management until there is evidence that such a high level of unnecessary intervention, as suggested by the treat-all strategy, does less harm than the occurrence of rare false negatives.

Passant en revue diverses situations empruntées à la vie quotidienne ou puisées dans des matériaux littéraires (écrits et surtout oraux, l'auteur relève diverses stratégies adoptées, soit par les injurieurs, soit par les injuriaires, pour tenter de maîtriser les effets des mots (ou gestes « déplacés ». Bien que le problème du contrôle de soi semble presque toujours primordial, la gestion de l'injure laisse apparaître une différenciation importante en fonction du sexe et du statut relatif des acteurs sociaux concernés.

    2003-01-01

    The Higgs boson was theoretically created about 40 years ago by a Scott Peter Higgs who wanted to explain why some particles get a mass. Since then the Higgs boson has taken consistency and has become an important point of the standard model theory. Its experimental discovery would be a milestone of modern physics. The search for the Higgs boson is an international challenge that takes place around 2 huge machines: the Tevatron near Chicago and the LHC (large hadron collider) that is being built in CERN. The Tevatron is in fact the upgrading of an old particle accelerator, it is a proton collider and its narrow range of energy is compensated by a low background noise. On the other hand the LHC will begin operating only in 2007 and its full power will be reached a few years later, the energy available to create particles will be then 7 times higher than for the Tevatron. Both machines have chance of succeeding by being the first to detect the Higgs boson. Time plays in favor of the Tevatron but in any case if ...

  7. The prescription pattern of Chinese herbal products that contain dang-qui and risk of endometrial cancer among tamoxifen-treated female breast cancer survivors in Taiwan: a population-based study.

    Directory of Open Access Journals (Sweden)

    Chien-Tung Wu

    Full Text Available PURPOSE: The increased practice of traditional Chinese medicine worldwide has raised concerns regarding herb-drug interactions. We analyzed the usage of Chinese herbal products containing dang-qui and investigated whether dang-qui therapy increases endometrial cancer risk among tamoxifen-treated breast cancer survivors in Taiwan. METHODS: All patients newly diagnosed with invasive breast cancer who received tamoxifen treatment from January 1, 1998, to December 31, 2008 were selected from the National Health Insurance Research Database. The usage, frequency of service and type of Chinese herbal products containing dang-qui prescribed across the 31,970 survivors were evaluated. Logistic regression method was employed to estimate the odds ratios for utilization of Chinese herbal products containing dang-qui. Cox proportional hazard regression was performed to calculate the hazard ratio of endometrial cancer associated with dang-qui use within the cohort. RESULTS: Almost one in two study subjects had used dang-qui. Among 31,938 tamoxifen-treated breast cancer survivors, 157 cases of subsequent endometrial cancer were identified. The hazard ratio for development of endometrial cancer among breast cancer survivors aged 20-79 years who had taken dang-qui after tamoxifen treatment was decreased compared to survivors who had never used dang-qui (HR: 0.61, 95%CI: 0.44-0.84. To minimise potential confounding factors, women with breast cancer in the reproductive age were excluded from further analysis, and the negative relationship between dang-qui consumption and subsequent endometrial cancer among breast cancer survivors aged 55-79 years was still observed, although not significantly (HR: 0.74, 95%CI: 0.46-1.17. CONCLUSIONS: Dang-qui consumption is common among breast cancer survivors aged 20-79 years and seems decrease the risk of subsequent endometrial cancer after less than a cumulative dose of 7,500 mg of tamoxifen treatment.

    2015-12-01

    Full Text Available Cibler la poétique d’Amprimoz est aussi problématique que situer une unique tendance littéraire, esthétique et philosophique chez le critique qu’était le professeur de littérature et de linguistique françaises : ses vastes intérêts et ses publications multiples dans des domaines aussi amples que la littérature canadienne française, la littérature pour la jeunesse, le symbolisme – de Germain Nouveau à Rimbaud, la sémiotique, entre autres –, sans oublier le crepuscolarismo italien et le modernisme anglophone, en font foi. Pour lui rendre hommage, je souhaite surtout explorer, dans la présente analyse, la relation ambigüe entre la poétique symboliste et l’écriture moderniste : la poésie d’Amprimoz semblerait réconcilier, par le biais d’un multilinguisme sans effort, la représentation artistique qui unit les pensées contradictoires d’un Stéphane Mallarmé et d’un Ezra Pound. Certes, la poétique d’Amprimoz reste essentiellement inclassable. Cependant, en l’inscrivant dans les courants littéraires qui le fascinaient tant, on est capable de déchiffrer un travail à la fois critique et poétique, qui rassemble des mouvements littéraires distincts et que l’on regroupe, souvent à tort, sous l’unique nomenclature anglophone de « modernisme ».

    2012-08-01

    Full Text Available Si le recueil Cœur élégie rouge de James Sacré fait bien apparaître l’ombre d’une femme aimée et perdue, ne voir dans cette élégie qu’une dimension autobiographique serait réducteur, et il faut peut-être y entendre aussi, selon une approche réflexive, le poème qui échoue à restituer le monde, le végétal, les visages. De la sorte, l’élégie serait aussi le deuil de ce rêve, avec le constat de l’incompatibilité du poème et du monde, pour peu que le sujet lyrique s’abandonne à un aveu naïf de son amour. Le poème doit donc se reconstruire comme espérance, projet incessamment relancé d’une écriture par quoi la vie continue. L’élégie ne se contente plus de chanter la perte ni de méditer sur l’inadéquation de la langue, elle tire sa force d’un espoir qui renaît toujours et dont témoigne la prégnance de la métaphore végétale.

    Full Text Available The article deals with the rhetoric and discursive strategies through which surrealist artist and writer Clade Cahun elaborates forms of self-representations which, by subverting gender norms, reinvent non only femininity but humanity overall. The analysis will be carried out on the basis of Roland Barthes’ reflections on androgyny which he elaborated during his course on Neutre at the Collège de France. For Barthes, Neutre is a vector of symbolic change: « un mélange, un dosage, une dialectique, non de l’homme et de la femme (génitalité, mais du masculin et du féminin. Ou mieux encore: l’homme en qui il y a du féminin, la femme en qui il y a du masculin ». Neutre is whatever breaks the binary opposition between terms A and B by assuming the form of either “not A nor B”, or “A+B”. Neutre is therefore an attempt to elude the doxa and all immutable binary scheme of meaning through linguistic and rhetoric strategies such as epicene nouns and names, impersonals, a fluctuant use of gender forms, amphibology, irony, paradox, parallelism, antiphrasis.

    Comme tous les travailleurs, les chercheurs ne peuvent échapper à l'évaluation. Celle-ci ne peut être conduite par eux-mêmes. De nombreuses questions se posent : qui doit les évaluer ? À quel rythme ? Et surtout, sur quelles bases ? Sur leur réputation, leurs interventions, leur implication dans la discipline, leur présence dans la littérature scientifique ? Mais alors quelle littérature ? Comment apprécier cette présence ? Par le nombre de textes publiés ? La diversité des revues ? Par l'écho qu'ont les textes dans la littérature ? La bibliométrie tend aujourd'hui à saturer l'évaluation. Elle est une réponse à quelques-unes de ces questions. Elle propose une forme d'évaluation comptable qu'on voudrait objective mais qui comporte de nombreuses limites et ambiguïtés.

    Full Text Available The only extant poem by Sail d’Escola, “Gran esfortz fai qui chanta ni·s deporta”, must have been quite successful with the troubadours since its melody was reused several times. Without a doubt its interest also lies in the fact that it mentions another (or others? poem in which the troubadour has recourse to the ‘mala canso’, believing, quite rightly, that he may offend the lady who proved to be a bad ‘amigua’. The text is ambiguous: it appears to be a love song asking for forgiveness to a lady who had previously been treated badly, but it also contains hidden threats of abuse, should the lady not show herself to be once more well-disposed towards her lover. This paper will propose a new interpretation of the simile in ll. 5-7, as well as some corrections to the previous edition (Chabaneau.

Analizar estos proveedores permite dar respuesta a preguntas en torno a los actores involucrados: quiénes eran; cuántos eran; qué porcentaje representaron dentro de la población del complejo portuario rioplatense en ese momento; si eran proveedores especializados en un solo bien, o iban rotando sus provisiones; si eran proveedores directos o eran “intermediarios” entre éstos y los destinatarios de los bienes y/o servicios; qué incidencia económica tuvieron sus provisiones dentro de los gastos totales del sitio y en comparación con la economía local del complejo portuario rioplatense; de esta manera se seguirá trabajando en el estudio de la estructura socio económica del Río de la Plata de ese momento, prestando especial atención a estos sectores medios y/o bajos. La detallada contabilidad del Proveedor General de la Expedición de la Colonia del Sacramento, ofrece una invalorable puerta de acceso a estos problemas, ya que a través de cientos de registros es posible establecer qué se compraba, quiénes lo proveían, cómo llegaba lo comprado a destino y todos los demás elementos que invitan a pensar en un mundo de la producción y la circulación mucho más rico y complejo que el conocido hasta ahora a través del gran comercio.

    Full Text Available Dans les mois qui suivent les attentats du 11 septembre 2001, face aux douleurs encore vives et à la phobie anti-terroriste qui gagne du terrain, rares sont ceux qui s’interrogent sur le caractère liberticide de l’arsenal juridique mis en place par l’administration Bush. Encore plus rares sont les observateurs qui choisissent de jouer la carte de l’humour et de la dérision. Pourtant, en dépit du contexte, le 15 décembre 2001, soit trois mois après les attentats, le quotidien d’Atlanta en Géorgie, The Atlanta Journal-Constitution, fait paraître un dessin humoristique de Mike Luckovich caricaturant la politique du ministre de la justice John Ashcroft. De prime abord, l’auteur de la caricature dénonce la diabolisation de l’ennemi interne que forme alors la communauté américaine de culture arabe ou islamique. Dans son dessin, Luckovich met en effet clairement en cause la pratique du profilage racial et le caractère artificiel de la division dichotomique mise en avant par l’administration fédérale. Cependant, le choix de caricaturer John Ashcroft, représentant notoire de la droite religieuse, nous porte à croire que c’est en fait la délicate problématique des relations entre pouvoir et religion qui est au cœur du message adressé par l’auteur.Le dessin humoristique constituant un instrument de lecture privilégié d’une époque, cette analyse sera l’occasion de mettre en évidence les sentiments d’une catégorie d’Américains qui, dans les mois ayant suivi la réaction des agences fédérales, se sont opposés aux manœuvres visant à réduire le patriotisme aux seules convictions religieuses.In the months following the September 11 attacks on New York and Washington when the anti-terrorist phobia was at its peak, very few Americans dared voice criticism of the Bush administration’s assault on civil liberties. Even fewer commentators dared to use humor in dealing with the tragedy. However, despite the

    Full Text Available Depuis moins d’une dizaine d’années, le double registre des valeurs et du récit de communication prend une importance croissante dans la conduite des projets urbains. C’est cette transformation de la production urbanistique, co-occurrente d’une transformation de la condition d’urbaniste, que discute cet article. Pour ce faire, il revient sur l’avènement d’un urbanisme de coordination consécutif à la généralisation de l’idéologie du projet urbain. Dans un deuxième temps, l’hypothèse d’une dématérialisation de l’urbanisme corrélatif à l’émergence d’un paradigme du mouvant est discutée. Enfin, l’émergence des valeurs et du récit dans la conduite de projet urbain, simultanément à un affaissement de la règle et de la regula, est envisagée du point de vue de la reconfiguration du champ de la pratique professionnelle qu’il occasionne.

    Full Text Available El sistema político mexicano ha experimentado transformaciones que han afectado hondamente el proceso legislativo. El poder Ejecutivo no sólo ha dejado de jugar un papel fundamental en este proceso, sino que, además, la descentralización política ha obligado a los legisladores a cultivar una reputación personal frente a los distintos actores con capacidad de dar continuidad a su carrera política. En este contexto, en necesario preguntar quién legisla en México. Para responder a esta cuestión, en este artículo se analizan los cambios observados en la forma de hacer la ley y la carrera seguida por los autores de las iniciativas aprobadas en la Cámara de Diputados durante las tres legislaturas que siguieron a la alternancia.The Mexican political system has undergone transformations that have deeply affected the legislative process. Not only has the executive branch stopped playing a key role in this process but political decentralization has forced legislators to cultivate a personal reputation in regard to the various actors able to lend continuity to their political careers.

In order to explore this issue, this article analyzes the changes observed in the ways of making laws and the career followed by the authors of the initiatives passed in the Chamber of Deputies during the three periods of office that followed the party alternation of the year 2000.

    Full Text Available Presentamos un análisis de las estrategias textuales de representación del campesinado indígena que se han desarrollado tanto desde la disciplina arqueológica como desde la etnohistoria. Cada una de estas disciplinas, a lo largo del tiempo, ha defendido sus modos diferenciales de acceso al pasado frente a los de la otra. Es nuestra intención mostrar cómo, a pesar de las diferencias marcadas en esas discusiones, ambas disciplinas parten de presupuestos comunes respecto del objeto de estudio por ellas construido. Se tomaron para los análisis diferentes textos referidos a la arqueología, historia o etnohistoria de la Puna de Atacama desde la conquista hasta el siglo XIX y se confrontaron con los resultados de nuestras propias investigaciones. Finalmente argumentamos que los discursos académicos nos dicen más acerca de quién escribe que sobre quienes lo hacen.Archaeological and ethnohistorical textual practices regarding indigenous peasantry are analyzed. Both disciplines, along their history, have defended their own specific methods of approaching the past against the methods of the other. We intend to show how, despite the differences noticed on those discussions, both disciplines are based on common cultural biases about their subject matter. For analytical purposes we use different texts from archaeology, history or ethnohistory of the Atacama Plateau from the Castilian Conquest to the twentieth century, which are also confronted with the results of our own research. It is argued that academic discourses tell us more about who writes than about who is being described.

El propósito de este artículo es analizar quién pagó en realidad los tributos cobrados sobre el vino en Madrid en el siglo XVII. La primera parte muestra que la creciente carga fiscal que recayó sobre el vino causó el desarrollo de un fraude masivo que perjudicó a los miembros del Gremio de Taberneros de la villa y a la hacienda real y municipal, en beneficio de todos aquellos que podían vender esta bebida de forma ilegal. La segunda parte indica que a pesar de la continua introducción de tributos sobre el vino en Madrid a lo largo del siglo, los niveles de consumo individual de esta bebida sólo se redujeron moderadamente. Pudiera alegarse que gracias al fraude los consumidores madrileños compraron vino a precios baratos, pero la evidencia ofrecida sugiere que no debió de ser así. De hecho, el vino vendido de forma ilegal apenas era un 5-10% más barato que el vendido legalmente por los taberneros. Según se muestra en la tercera parte, los precios del vino vendido en Madrid a lo largo del siglo XVII tanto en los mercados legales como

Antes de ofrecer algunas puntadas analíticas de apertura a este número, comenzaremos la disertación comentando que el azar quiso que la elaboración de esta introducción se haya dado entre la firma protocolaria de los acuerdos de paz entre el Gobierno colombiano y las Fuerzas Armadas Revolucionarias de Colombia - Ejército del Pueblo (farc-ep del 26 de septiembre y el inesperado rechazo de estos en el plebiscito del 2 de octubre del 2016. En esta transición histórica, esculpida con dolores, fallos, paciencias y esperanzas, las prácticas y las políticas de la memoria han desempeñado una función crucial, marcando los términos del debate en cuanto a la agencia y al estatus de las víctimas, la puesta en marcha de una justicia transicional y la redefinición de Colombia como país. El título Memorias del presente y del futuro corresponde precisamente a esta coyuntura, en la que convergen relatos de vida abortados, así como procesos históricos de amplio alcance, tácticas y estrategias de resistencia, macro- y micropolíticas. Al formular la convocatoria para el número teníamos en mente que la memoria, como acto colectivo de rememoración, articula el pasado, el presente y el futuro, y queríamos ir más allá de la noción habitual de memoria como anclada en el pasado, focalizada en una serie de hechos que se sitúan en un tiempo y un espacio que resultan significativos para alguien desde el presente. Si bien el pasado parece un país extraño al que queremos retornar, como lo ha dicho el escritor David Lowenthal (1998, igualmente, asumimos que la memoria es un

These sources are: waste water discharges, an urban solid waste dump, situated in the very bed of the stream, and the intensive aggregate extraction which made the stream itself disappear at various points. This article also deals with the recuperation of the surrounding wood in a natural and landscape-friendly way, which would facilitate the access and the walk along the sides of the stream. This would lead to the clearing of other areas of a high ecological value within this municipality.

    Our climate crisis may at times appear to be happening slowly, but in fact it is happening very quickly-and has become a true planetary emergency. The Chinese expression for crisis consists of two characters. The first is a symbol for danger; the second is a symbol for opportunity. In order to face down the danger that is stalking us and move through it, we first have to recognize that we are facing a crisis. So why is it that our leaders seem not to hear such clarion warnings? Are they resisting the truth because they know that the moment they acknowledge it, they will face a moral imperative to act? Is it simply more convenient to ignore the warnings? Perhaps, but inconvenient truths do not go away just because they are not seen. Indeed, when they are responded to, their significance does not diminish; it grows. (author)

    Full Text Available Bone mineral density (BMD is the tool for diagnosing osteoporosis in older adults. However, BMD alone is not sufficient for deciding who should be given treatment at either the individual patient or the public health level. Robust, scientifically validated algorithms that combine BMD with other clinical risk factors provide more accurate assessment of fracture probability. New guidelines for managing osteoporosis are now based on the assessment of absolute fracture risk, not simply on bone mineral density values. Accordingly, treatment resources will be redirected away from young postmenopausal women with low BMD and low fracture risk toward older adults at moderate or high risk for fracture. It is expected that, with these algorithms, the cost and effectiveness of medical care for patients with osteoporosis will be improved.La densidad mineral ósea (DMO es la herramienta de diagnóstico para osteoporosis en adultos mayores. Sin embargo, por sí sola la DMO no es suficiente para decidir quién debe recibir tratamiento ni al nivel del paciente individual ni al nivel de salud pública. Los algoritmos robustos, científicamente comprobados, que combinan DMO con otros factores de riesgo clínicos proporcionan una evaluación más precisa de la probabilidad de fractura. Los nuevos lineamientos para el manejo de la osteoporosis se basan en la evaluación del riesgo de fractura absoluto, no ya tan sólo en los valores de densidad mineral ósea. Por lo tanto, los recursos para el tratamiento cambiarán, de dirigirse a mujeres postmenopáusicas jóvenes con baja DMO y bajo riesgo de fractura, a mujeres mayores con riesgo de fractura alto o moderado. Se espera que con estos algoritmos haya una mejora en cuanto al costo y la efectividad de la atención médica para pacientes con osteoporosis.

    Full Text Available Desde finales del siglo XX, gobiernos locales de diferentes ciudades de América Latina implementan políticas urbanas de corte neoliberal. El objetivo es re-configurar ciudades económicamente productivas. Para ello, se busca el mejoramiento del factor de localización de estas a través de la atracción de visitantes e inversionistas. Con ello, se da el paso de una lógica de gobernanza urbano gerencial a “la ciudad empresarial”. Una de las implicaciones más significativas es el carácter selectivo que toman los espacios públicos. Concretamente, se los convierte en nuevas centralidades orientadas, fundamentalmente, al consumo de sectores de altos ingresos. Esto deriva en una producción del espacio público, que profundiza la polarización socio-económica y la configuración de ciudades fragmentadas y desiguales. Sin embargo, la producción de un determinado espacio se realiza tanto desde las políticas urbanas, como desde los actores del lugar. En este sentido, el espacio público es uno de los lugares en los cuales se materializa la tensión entre estas dos escalas. Tensión que se deriva a partir de la disputa por quien instalará los parámetros de cómo y quién podrá habitar y consumir el espacio público. En esta línea, el presente trabajo analiza la producción de espacios públicos en dos casos de estudios latinoamericanos: la construcción del Boulevard Naciones Unidas, en la ciudad de Quito, y la renovación urbana del barrio La Boca, en la Ciudad de Buenos Aires.

    The University of Québec in Montréal has agreements with trade unions providing access to university resources. Researchers involved in this program worked in partnership with union women's and health and safety committees for more than twenty years. Not all studies succeeded in improving women's working conditions. One joint project involved observational studies of tasks done by health-care workers, complemented by interviews and questionnaires. We found that task assignments, movements, postures, and work-related musculoskeletal disorders varied by gender/sex and made recommendations for change. However, issues of pay equity, spending on health care, and contracting-out of "ancillary work" were salient. Researchers learned that in the absence of changes in power relationships in the workplace, women may be disadvantaged by denial as well as by exaggeration of female-male differences. Men may also be at risk when their gender is invisible. We suggest some feminist approaches to workplace solutions and some pathways for research. Résumé L'Université du Québec à Montréal a signé avec des centrales syndicales des ententes leur donnant un accès à des ressources universitaires.

  9. Adieu, de Balzac : « Une absence au monde qui vient de se déclarer au cœur de l’histoire »

    Full Text Available Balzac s’est toujours intéressé au sort des victimes « oubliées » des campagnes napoléoniennes et, outre Le Colonel Chabert, on rencontre dans son œuvre plusieurs figures de vieux grognards, mutilés ou survivant avec une maigre pension. Mais il est une nouvelle peu connue, Adieu, dont le sujet manifeste une préoccupation étonnamment moderne, et si insolite à son époque qu’il conduit le romancier à inventer une forme narrative inédite et surprenante, dont je tenterai de montrer qu’il l’emprunte au discours et à la pratique psychiatrique alors récemment mis en œuvre par Esquirol. Il s’y agit d’une femme, chose rare, qui a été traumatisée par les horreurs de la retraite de la Bérésina (où elle accompagnait son mari et, après des années d’errance, est devenue folle et muette sans qu’aucun traitement soit parvenu à la guérir. La nouvelle, qui relève l’invraisemblable défi de nous faire pénétrer l’univers d’une folle aphasique, évoque le stratagème spectaculaire qu’invente son ancien amant pour éveiller un instant sa raison et sa parole, avant qu’elle ne meure, et qu’il se suicide dix ans après. Non sans éveiller chez le lecteur des abîmes de réflexion sur cette victime « collatérale », et le recentrement de l’Histoire.Balzac siempre se interesó por la suerte de las víctimas «olvidadas» de las campañas napoleónicas. Además de El Coronel Chabert, en su obra se pueden encontrar muchos personajes de viejos gruñones, mutilados o supervivientes con una reducida pensión. Pero es en una novela muy poco estudiada, Adieu, donde el tema ofrece una preocupación asombrosamente moderna y tan insólita para su época que obliga al novelista a inventarse una forma narrativa inédita y sorprendente, Mi intención es mostrar que Balzac toma esta forma del discurso y la práctica psiquiátrica, desarrollada en aquel entonces por Esquirol. La novela trata de una mujer, cosa rara

    éterminants environnementaux jouent un rôle clé pour modeler la maîtrise de soi dans le processus d’apprentissage. Cet article rapporte une étude sur les influences de l’environnement de cyberapprentissage 2.0 sur la maîtrise de soi. L’étude a cerné les facteurs qui, dans un tel environnement, influencent la maîtrise de soi et déterminent les relations entre les facteurs et la maîtrise de soi. Un modèle théorique de catégorisation des facteurs de réussite pour l’apprentissage autogéré a été proposé pour ce type d’environnement. Un questionnaire a été conçu selon ce modèle et plus de deux cent cinquante élèves en téléapprentissage à Beijing et à Hong Kong y ont répondu. À l’aide d’une technique de modélisation par équation structurelle, les relations entre les facteurs environnementaux et l’autogestion ont été analysées. Les résultats statistiques ont démontré que plusieurs facteurs affectent l’autogestion dans l’environnement de cyberapprentissage 2.0. Ceux-ci comprennent la qualité du système, la qualité de l’information, la qualité du service et la satisfaction de l’usager.

    Full Text Available Cet article s’articule autour d’une source, le rapport préliminaire de la Commission royale d’enquête sur le bilinguisme et le biculturalisme, qui permet, à l’aide de bribes de témoignages de citoyens canadiens et de l’analyse des commissaires, de pénétrer les mémoires québécoise et canadienne, qui évoluent en vases clos. Paru en 1965, le rapport préliminaire révèle au grand jour l’intensité de la crise canadienne, une intensité telle qu’elle menace, aux yeux des commissaires, l’unité du pays. Comment se manifestent les traces du passé au sein du rapport ? Qu’est-ce que le document révèle sur les mémoires canadienne et québécoise ? Où la crise décrite par les commissaires puise-t-elle sa source ? Tels sont les questionnements qui nous intéresseront. À travers l’analyse du rapport préliminaire, se dégage toute la complexité des rapports canado-québécois. Se dégage également des pistes de solutions qui sont encore criantes d’actualité.This article is about a source, the Preliminary Report of the Royal Commission on Bilinguism and Biculturalism, that permits to enter, through the fragments of testimonies of Canadian citizens and their analysis by the commissers, in the Quebecers and Canadians’ memories, which evolve in two ways apart. Published in 1965, the Preliminary Report had the effect of a bomb in revealing the intensity of the Canadian crisis, which threatens, according to the commissers, the Canadian unity. How does the tracks of past manifest themselves within the report? What does the document reveal on the Canadian and Quebecois memories? Where does the crisis described by commissers draws its source? Such are the questionings which will interest us. Through the analysis of the preliminary report, all the complexity of the Canado-Quebecois connections is appearing. Also appears some solutions which are still of a profound actuality.

    Full Text Available Taking into account that the Romanian Constitution mentions the "state of law" and "constitutional democracy", concomitantly specifying the essential values- human dignity, citizens' rights and freedoms, the free development of human personality, justice and political pluralism- defended by the domestic legal order, it seems of a real practical interest to notice the concrete means established in order to protect the above mentioned values. As it has been mentioned before, the contentious administrative represents one of the most efficient ways under which the values constitutionally affirmed are guaranteed and defended. The contentious administrative basically answers the old question: "Quis custodiet custodes?", question that comprises one of the most difficult obstacles against the state of law actualization: to find the most efficient procedural ways for the state bodies able to use, directly or indirectly, the coercion force in order to make the citizens observe the laws, to be in their turn under the situation to observe the same laws. As the contentious administrative represents the courts of law activity meant to settle the conflicts whereas at least one of the parties is a public authority, we will try, while evoking procedural aspects, procedural means available for someone prejudiced by a public authority, to stress the weight of the procedural rules in guarantying and defending effectively the citizens' rights and legitimate interests.

    Full Text Available Aunque el objetivo óptimo del tratamiento de la Hepatitis B, sería la erradicación del virus, con las terapias con que contamos, en la actualidad, esto se consigue en un porcentaje mínimo de los pacientes. Por lo tanto, según el conocimiento actual, queda claro que el tratamiento que genera y logra mantener una supresión de larga duración del HBV DNA en niveles indetectables, reduce la incidencia de enfermedad hepática avanzada y hepatocarcinoma y este debería ser el objetivo que se plantee al tratar a los pacientes. Para la decisión de qué pacientes tratar debe considerarse su perfil clínico, perfil serológico, bioquímico y valores de carga viral. En algunas ocasiones, el clínico completará el estudio con una biopsia hepática. Hay tres grupos de pacientes por considerar cuándo se evalúa el paciente para darle tratamiento y todos tienen criterios distintos que guiarán la decisión del médico tratante, a saber: pacientes con hepatitis crónica HbeAg positivo, pacientes con hepatitis crónica HbeAg negativo, pacientes con enfermedad hepática avanzada.

    Out of the scope of the usual positions of computing in the field of music and musicology, one notices the emergence of human-computer systems that do exist by breaking off. Though these singular systems take effect in the usual fields of expansion of music, they do not make any systematic reference to known musicological categories. On the contrary, they make possible experiments that open uses where listening, composition and musical transmission get merged in a gesture sometimes named as ?music-ripping?. We will show in which way the music-ripping practices provoke traditional musicology, whose canonical categories happen to be ineffectual to explain here. To achieve that purpose, we shall need: - to make explicit a minimal set of categories that is sufficient to underlie the usual models of computer assisted music;- to do the same for human-computer systems (anti-musicological?) that disturb us; - to examine the possibility conditions of reduction of the second set to the first; - to conclude on the natur...

A global evaluation report about these researches is to be supplied in 2006 by the French government to the Parliament. A first synthesis of the knowledge gained after 14 years of research has led the national commission of the public debate (CNDP) to organize a national debate about the general options of management of high-level and long-lived radioactive wastes before the 2006 date line. The debate comprises 4 public hearings (September 2005: Bar-le-Duc, Saint-Dizier, Pont-du-Gard, Cherbourg), 12 round-tables (October and November 2005: Paris, Joinville, Caen, Nancy, Marseille), a synthesis meeting (December 2005, Dunkerque) and a closing meeting (January 2006, Lyon). This document is the synthesis of the round table debates which took place at Marseille.

    Full Text Available Planning, conducting, and reporting leading-edge research requires professionals who are capable of highly skilled reading. This study reports the development of an empirically informed computer-based learning environment designed to foster the acquisition of reading comprehension strategies that mediate expertise in the social sciences. Empirical data were gathered in a mixed-methods explanatory sequential design that examined the reading comprehension strategies used by an expert social scientist while reading a professional-level text. Process data were collected through a concurrent think-aloud protocol and coded according to reading comprehension processes. We combined both quantitative and qualitative analyses to identify, describe, and explain patterns in the expert’s use of reading strategies. Our findings indicate that highly-skilled reading is characterized by critiquing text information, relating information to prior knowledge, and evaluating one’s own understanding of text information. Findings are used to inform the design of worked-examples and a pedagogical agent embedded within the Highly-Skilled Reading Tutor.

    Full Text Available Production processes are monitored by control charts since their inception by Shewhart (1924. This surveillance is useful in improving the production process due to increased stabilization of the process, and consequently standardization of the output. Control charts keep track of a few key quality characteristics of the outcome of the production process. This is done by means of univariate or multivariate charts. Small improvements in control chart methodology can have significant economic impact in the production process. In this investigation, we propose the monitoring of a single variable by means of a variable parameter non-central chi-square control chart. The design of the chart is accomplished by means of optimizing a cost function. We use here a simulated annealing optimization tool, due to the difficulty of classical gradient based optimization techniques to handle the optimization of the cost function. The results show some of the drawbacks of using this model.Processos de produção são monitorados por gráficos de controle desde a sua introdução por Shewhart (1924. Este monitoramento é útil na melhoria do processo de produção devido à crescente estabilização do processo, e consequentemente, padronização do produto.

The quality of spirulina produced in these developing countries continues to increase to the extent that it can now be exported. Thus, associations such as Spirulidaire market a traditional, fair and supportive spirulina in France and Europe and thus promote local producers.The perception of spirulina continues to evolve with the multiplication of field initiatives and the accumulation of scientific data.

    neutralizzazione dei possibili rinforzi negativi che provengono invece dai “non-giocatori”.Dans cet article, l’auteur analyse les caractéristiques de ce qu’elle a appelé « sous-culture des jeux de hasard », décelable dans certains milieux de loisirs et dans les sous-groupes de joueurs particulièrement « acharnés ». Parmi ces formes de sous-culture, l’article va identifier les règles et les sanctions, les valeurs, les comportements durables, la caractérisation des relations et des interactions, en concluant que ce qui est construit dans l'espace du jeu est un univers séparé, une «réalité extérieure» dans laquelle des nouvelles règles sont écrites et où les valeurs changent par rapport au «monde extérieur» . Il a également été possible de conclure que l'adhésion à l' «univers du jeu» - l'internalisation de ses normes, le partage de ses valeurs, le développement des relations en son sein - est un facteur de maintenance de la conduite du jeu, car cette adhésion permet d'envisager comme «normal» son propre comportement grâce à des réactions positives provenant des compagnons de jeu et à la neutralisation d’éventuelles réactions négatives provenant des «non joueurs».

    Full Text Available En la literatura de gestión y de la Psicología del Trabajo y de las Organizaciones existe una sobreabundancia de testimonios referidos a la influencia positiva de los equipos de trabajo sobre variables psicosociales y sobre los resultados económicos de las empresas donde se implantan. Sin embargo, sospechamos que tal sobre representación de éxitos no siempre refleja la realidad de las empresas. Este trabajo pretende realizar un análisis de las dificultades que la implantación de equipos de trabajo conlleva en los procesos de reestructuración del poder y de la organización del trabajo. También se examinarán algunas de las resistencias de carácter individual que suelen aparecer al iniciar procesos de reestructuración organizacional en base a equipos de trabajo. Este artículo no pone en duda la potencialidad de los equipos de trabajo, lo que cuestiona es que puedan llegar a ser efectivos sin una adecuada dirección, estructura, formación y facilitación. Desarrollando una apreciación más crítica de los costes y beneficios de la implantación de sistemas de trabajo basados en equipos esperamos favorecer un uso más apropiado de los mismos.

    Full Text Available Les bouleversements intervenus ces dernières décennies dans la composition de l'ichtyofaune d'eau douce française incitent, d'une part, à faire un bilan de la situation présente (cf. l'Atlas des poissons d'eau douce de France et, d'autre part, à promouvoir une politique de gestion cohérente avec le principe de protection du patrimoine biologique naturel. Cette notion de patrimoine reste toutefois à définir. En effet, les changements actuels ne sont que les derniers d'une longue série, où l'homme est un acteur capital depuis plus longtemps qu'on ne le croit. De fait, beaucoup des espèces dites françaises n'ont probablement pas de valeur patrimoniale dans nombre de nos bassins fluviaux. Le présent article a pour ambition de décrire l'ampleur du problème et de solliciter la communauté scientifique, afin de rassembler les informations et développer les investigations selon un cadre géographique et historique précis.

Se llevó a cabo una revisión conceptual, desde la sociología del trabajo y las diferentes formas de flexibilidad. Asimismo, se hizo una indagación documental relativa a la normatividad en el transporte revisando algunas de las declaraciones de actores involucrados en la prestación de este servicio ante el debate suscitado por la entrada de Uber a México. Como resultado se encontró que Uber replica el modelo de gestión del taxi tradicional, en relación con la flexibilidad en la organización y relaciones de trabajo.

    Full Text Available Au Québec, en santé au travail, l’approche de santé publique a été privilégiée à l’approche médicale individuelle, parce qu’elle est conséquente aux objectifs de la loi, à savoir la prise en charge par le milieu de ses problèmes et la diminution, voire l’élimination des dangers. Quant aux activités médicales individuelles, elles ne sont réalisées que lorsqu’elles sont légitimes, c’est-à-dire lorsque leur pertinence et leur efficacité sur le plan de la prévention ont été démontrées. Quelques évaluations l’ont confirmé, l’approche par programme des services de santé publique québécois fonctionne en général très bien et elle est efficace. Mieux que l’examen médical de chaque sujet, elle permet de centrer les énergies sur les expositions professionnelles et les composantes de l’organisation du travail susceptibles de provoquer des problèmes. Malgré toutes ses qualités, le système de santé au travail québécois se heurte à de sérieuses résistances institutionnelles et politiques qui ont compromis son développement et mènent progressivement à son essoufflement.In Québec, in occupational health, the public health approach has been favoured over the individual medical approach because it is consistent with the objectives of the law, namely this community taking charge of its problems, and the reduction and even elimination of risk factors. Individual medical activities are limited to cases where the relevance and effectiveness of preventive benefits have been demonstrated. Some evaluative studies have shown that this Québec public health program approach works well in general, and is effective. Compared with the medical examination of each subject, it has a better potential for focusing energies on occupational exposures and on work organizational factors that could cause problems. Despite all its advantages, the Québec occupational health system is facing serious institutional and

En primer lugar se analiza el proceso de construcción social del propio concepto de “infancia y adolescencia en dificultad”, a la luz de los cambios que se han producido, especialmente a lo largo del último siglo, en las ciencias sociales y su repercusión en la formación de una idea de infancia en el imaginario colectivo. En segundo término, se aborda la condición de ser niño o adolescente en la llamada “sociedad del riesgo”, caracterizada, entre otras cosas, por la incertidumbre y los deseos de alcanzar un cierto control sobre los peligros percibidos como potenciales. La percepción de los riesgos para la infancia en la sociedad tiene dos caras: por un lado los peligros a los que están expuestos y por otro aquellos que causan, esto es, lo que nos amenaza. Para conjurar estos riesgos se exige mayor control por parte de las instituciones que regulan la vida de los niños (la familia, la escuela o el sistema de protección. El resultado es una restricción de la autonomía de los niños, niñas y adolescentes, que contrasta con las expectativas de que, como “hijos de la modernidad”, sean capaces de elegir sus propios caminos de autorrealización.-------------------------------------------------------------------This article tries to be an invitation to a journey in which the shared safeties taken for granted on the reality of the children and today teenagers, are being put in question, looking for other alternative explanations, which enable us to approach the study of the lives of the children, or the interventions with children (be they or we who meet in difficulty with a different look. First it is analyzed the process of social construction of the proper concept of "childhood and adolescence in difficulty", in the light of the changes that have taken place, specially throughout last century, in the social sciences and its repercussion in the social images of childhood. In the second term, it is approached the condition to be child or teenager in so called "risk society", characterized, among other things, by the uncertainty and the desires to reach a certain control on the dangers perceived as potentials. The perception of the risks for the childhood in the society has two faces: on the one hand the dangers to those who are exposed and for other one those that they cause, which threatens us. To conspire these risks it is required major control on the part of the institutions that regulate the life of the children (the family, the school or the protection system. The result is a restriction of the autonomy of the children and teenagers, which confront with the expectations of whom, as " children of the modernity ", are capable of choosing their own ways of self-realization.

    Full Text Available A partir de 1990 la legislación colombiana ha tenido significativos avances para permitir que todas las personas puedan acceder a los servicios de telecomunicaciones, tal como corresponde en ejercicio del derecho fundamental del acceso a la información. Gracias al desarrollo de la tecnología, la limitación que generaba la necesidad de utilizar frecuencias radioeléctricas ya no es una razón válida desde el punto de vista constitucional para restringir el establecimiento de nuevos servicios y la difusión de información. Esta realidad técnica debe ser reconocida por el ordenamiento jurídico respecto de todos los servicios de telecomunicaciones. Dentro del actual marco constitucional no existe ningún fundamento para que los servicios que no utilicen frecuencias radioeléctricas sean objeto de reserva estatal. Este reconocimiento ya lo hizo el legislador al establecer que el servicio de telefonía pública básica conmutada local no sea objeto de concesión. En el mismo sentido, los medios masivos de comunicación, incluida la televisión, que no requieran el uso de frecuencias radioeléctricas y que puedan ser trasmitidos a través de redes de cable, gozan del derecho constitucional de establecerse libremente, aunque deben someterse a los reglamentos del servicio que establezca la autoridad competente. Las disposiciones legales que actualmente no permiten el ejercicio de tal derecho, son inconstitucionales. / Since 1990 Colombian telecommunication law has had significant advances allowing everybody access to telecommunication services in exercise of the fundamental right of information. Technology development permit that the limitation which generated the need of use frequencies, know days is not a valid reason -from a constitutional point of view- to restrict the operation of new telecommunication services and the information diffusion. This technical reality, have to be recognize in the legal order among all the telecommunication services. Colombian constitutional framework, does not has any rule that allow the restriction of telecom services which do not use frequencies under a "state reserve regime". Legal recognition in this sense, has been made by the legislator, when he established that the local telephony service does not required concession for its operation. In the same sense, massive media operators -including television operators- which do not use frequencies and which can be transmitted by wires, can be freely established observing only the specific service regulation dictated by the telecommunication authority. Legal dispositions that today do not allow the exercise of this constitutional right are illegal.

The paper argues that states are morally constrained in the sorts of criteria they can use to exclude and select immigrants. In particular, they normally cannot use racial or ethnic criteria in selection. Furthermore, states have an obligation to admit as immigrants the immediate relatives (spouse and minor children or current and permanent residents and an obligation to accept refugees who apply for asylum.

Igualmente, se discute el papel de la universidad, como ente determinante en la calificación y profesionalización del Recurso Humano. Su quehacer en el campo de la investigación,  su liderazgo en el tratamiento de los grandes conflictos nacionales, su papel en el manejo de las organizaciones  empresariales, etc. Tradicionalmente, la universidad encaminó su acción hacia la formación de profesionales con capacidad de enfrentar los retos del mundo productivo, como empleados. Sin embargo, en los últimos 20 años el modelo cambió. Hoy la sociedad espera empresarios que generen su propio  negocio y contribuyan al fomento de nuevos empleos.

    Full Text Available The fall of the Visigothic Kingdom of Toledo from the Muslim incursion in the year 711 has been generally explained by specialists as an inevitable consequence of a disintegration process in the Visigothic power structures. Historians have associated this situation to a confrontation – either direct or indirect – between Hispanic-Visigothic monarchy and aristocracy, being the standstill of the kingdom (caused by its administrative, military and judicial institutional incapacity also considered. In this paper, as opposed to the fatalistic perspective where the idea of an inevitable end was irrationally imposed, a different explanation is proposed based on the multiple power dynamics, the Kingdom’s defense mechanisms and the last Visigothic monarchs’ legislative activity. All these ideas will be framed into the context of the (unstable normality and the efficacy of the Visigothic institutional machinery.

Les anomalies biochimiques et comportementales sont partiellement réversées par une supplémentation avec des phospholipides, notamment extraits d’oeuf enrichis en ω3 ou de cervelle de porc. Une étude effet-dose montre que les phospholipides d’origine animale sont plus efficaces que ceux d’origine végétale pour réverser les conséquences du déficit, dans la mesure, entre autres, où ils apportent les très longues chaînes pré-formées.

Cautivos del sistema de transporte masivo, operado hoy en su totalidad por empresas privadas; desprotegidos por un Estado debilitado y permeable al poder de lobby de los concesionarios, ven desdibujarse hasta casi desaparecer el concepto de servicio público, cuya esencia implica la garantía de universalidad de las prestaciones. Presentamos la medición de la accesibilidad departamental, relacionando oferta de transporte masivo con población residente y niveles de pobreza. El análisis de su distribución socioespacial explicaría las incidencias con que los costos de transporte gravitan sobre los estratos más desprotegidos, los que por sus características y localización, no conforman mercados rentables para la operatoria privadaThis article pretends to demostrate, specially about the case of the metropolitan public transport system, how the changes to the state structures, resulting from the new flexible ownership patterns, impact to the detriment of increasing groups of captive users. The mass transport system, now operated solely by private operators, without sufficient regulatory protection, shows the gradual disappearance of public service concept, since weakness state is more receptive to the lobbying power of the concessionaires. With that objective, we present the results of our accessibility departmental measurement, by comparing the amount of public transport service offer with the number of residents and poor levels. The analysis would explain a socio-spatial pattern of higher costs of public transport in areas where the most vulnerable population groups are located due to the lack of profitable markets to be served

    Women were not "silent" at all in the Middle Ages, but the feminine way to compose texts at that time was oral, being made in the native Jewish-Languages, while Hebrew – known almost only by men - was the language of the written Literature. In this essay we will deal with the (self-representation of women in the Judaeo-Provencal medieval literary corpus. First, we will analyze some texts, explicitly composed for women, in order to understand the feminine perspective and literary liking as a public. Second, we will deal with an example of women literary creativeness, i.e. a particular Jewish blessing, transmitted in three extant Jewish prayerbooks (XV century, which recites: “Bless you God, for I was born a woman”. This probably refers to a local tradition of Provencal Jewish women who created it during the Middle Ages.

    Directory of Open Access Journals (Sweden)

    Pinilla Cañadas, Scheherezade

    2016-06-01

    Full Text Available This article attempts to answer all those scholars who maintain that Hannah Arendt is a political thinker of Hellenic nostalgia. From such a perspective, it is easy to conclude not only that Arendt´s thought is irrelevant to contemporary concerns but that she is an elitist reactionary when it comes to assessing the prospects of representative democracies. It is to be considered here that this reading is wrong and one-sided, and that the major work upon which it is based, The Human Condition, needs to be studied in a nuanced way, as engaging in multiple complex dialogue with philosophic-political tradition. To this end, this paper begins by briefly explicating not at all her dependency upon Heidegger, but rather a “radical conversation” with him. This conversation, even when only partially explored, casts considerable light on Arendt´s entire philosophical project. Secondly, this paper supports the view that Homer offers an ideal vantage point from which to tackle what Miguel Abensour has called “a political conception of heroism.” More specifically, the thesis which is to be defended here is that Iliad, and particularly the catalogue of ships in Book 2, could be understood as the origin of the Arendtian account of plurality.Este artículo pretende dar respuesta a toda esa crítica que sostiene que Hannah Arendt es una pensadora política con nostalgia de la pólis. Desde esta perspectiva, no resulta muy difícil concluir, no sólo que el pensamiento de Arendt es irrelevante en relación con los problemas contemporáneos; sino que estamos ante una auténtica reaccionaria cuando se trata de analizar las grandes cuestiones de las democracias representativas. Aquí se entiende que esta lectura es errónea y parcial y también que la obra sobre la que dicha interpretación se articula, La condición humana, debe ser estudiada de un modo mucho más sutil; que pasaría por un diálogo múltiple y complejo con la tradición filosófico-política. A tal fin, se hace una breve exposición, no tanto de su dependencia con Heidegger, cuanto de su “conversación radical” con él. Esta conversación (si bien sólo se estudia parcialmente arroja mucha luz sobre el proyecto filosófico de Hannah Arendt en su conjunto. En segundo lugar, en este trabajo se postula que Homero ofrece una perspectiva inmejorable a la hora de analizar lo que Miguel Abensour ha denominado “una concepción política del heroísmo.” De manera más específica, la tesis que aquí se defiende es que la Ilíada, y particularmente el catálogo de las naves del Canto II, podrían ser interpretados como el origen del concepto arendtiano de pluralidad.

  1. ¿A quién beneficia el comercio paralelo de medicamentos en la Unión Europea?

    Full Text Available El comercio paralelo constituye un movimiento legal (arbitraje comercial de productos de un país donde éstos se han puesto en circulación a otro país sin la autorización y la garantía del que posee los derechos de propiedad intelectual del producto. Este fenómeno se deriva de la aplicación del principio de subsidiariedad que lleva asociado la existencia de diferentes sistemas de regulación de precios y el de libre movilidad de bienes. En este artículo examinamos las tendencias de precios y penetración de medicamentos paralelamente importados respecto al precio del producto en el país de destino (beneficios de una mayor competencia en 2002. En segundo lugar, establecemos una descomposición empírica de los efectos del comercio paralelo de medicamentos en los tres mercados principales de la Unión Europea en los diferentes agentes de la cadena del medicamento. Los resultados no siguieren pruebas de un efecto competitivo del comercio paralelo. Por otra parte, se observa que los principales beneficiarios son los propios importadores paralelos en la medida que el comercio paralelo genera ahorros muy limitados en la factura de los sistemas de salud, que difícilmente superan los perjuicios en la innovación farmacéutica.

  3. Non bene olet qui bene semper olet! Incenso e aromi e fenomenologia dell’eros presso i Greci

    Directory of Open Access Journals (Sweden)

    Sara Petrucci

    2012-06-01

    Full Text Available Nel mondo greco i profumi sono sempre stati correlati al concetto di ἡδονή, termine che designa, in senso lato, la voluttà e la dedizione alle mollezze e ai piaceri dell’esistenza. Le essenze richiamano uno stile di vita raffinato, talvolta effimero e superficiale, ma sempre seducente e appetibile. L’assenza di ogni fragranza rappresenta invece il rifiuto di una realtà impalpabile ed eterea, rifiuto che va di pari passo con la condanna delle varie artes del lusso. Nell’ambito dei sentimenti e dell’attrazione amorosa la forza magnetica degli aromi costituisce un elemento essenziale dell’eros, poiché la donna -sia essa sposa legittima, o amante spregiudicata- acquista la charis attraverso il profumo, che ne esalta il fascino ren­dendola oltremodo sensuale. Generalmente considerati sinonimo di perversione, gli aromi non sono dunque completamente banditi dalla vita quotidiana, anche se il loro impiego è pericoloso poiché ogni forma di seduzione, seppur legittima, reca in sé il principio di una minaccia di corruzione. In the greek world aromas and perfumes have been always correlated to the conception of ἡδονή, word which indicates, in a broad sense, delight and devotion to the looseness and luxury of the existence. Essences remind a life-style refined, sometimes ephemeral and superficial, but always tempting and pleasing. The absence of perfumes represents, on the other hand, a refusing of a impalpable and ethereal reality, and it is, at the same time, a condemnation to various kinds of luxury. In the world of feelings and erotic attraction the strong power of aromas is an essential thing because women -lawful brides or open-minded lover- get the charis with perfume, that exalt female glamour. However essences are generally judged proof of perversion, they aren’t totally excluded, even if it could be dangerous because every kind of seduction can easily becoming a threat of corruption.

    The aim of this work is to show the implication of the experimental parameters (welding temperature, temperature holding time, lining pressure, surface states, atmosphere) on the bonds quality. On the other hand, the feasibility of an homogeneous bond has been shown on two materials prepared by the Haynes firm: the HR-120 (iron-nickel-chromium alloy which has good properties at high temperature: 1100 C) and the HR-230 (other iron-nickel-chromium alloy which has a very good resistance at high temperature: until 1150 C and at oxidation too). The study of welding specimens by metallographic analysis allows to conclude to the establishment of healthy bonds, particularly if the experimental parameters are scrupulously respected. (O.M.)

    Full Text Available La consideración sistemática, comprehensiva, teórica y analítica del diasporismo y las diás- poras es relativamente reciente. Sus primeros análisis sistemáticos comenzaron a producirse en la década de 1980, de modo que existen todavía lagunas significativas en su investigación y análisis así como en la formulación de un panorama general del diasporismo y las diásporas. En consecuencia, existen también dificultades en cuanto a una plena comprensión abarcadora del fenómeno. Al pasar revista a la literatura existente sobre diasporismo y diásporas, se evidencia que la comprensión de las diásporas en general, y particularmente de, por una parte, su reciente involucramiento en política, terrorismo y actividades criminales en los países receptores y, por la otra, sus contribuciones culturales, sociales, políticas y económicas a dichos países y a sus patrias de origen, está muy lejos de ser exhaustiva. Con el objeto de dar cuenta de modo más preciso sobre las particularidades del fenómeno, en este artículo se describe y analiza el fenómeno diaspórico en toda su amplitud, dejando a un lado las miradas convencionales que han obstaculizado y restringido significativamente el alcance del debate sobre el fenómeno diaspórico etno-nacional-religioso en general, y sobre las contribuciones o amenazas generadas por dichas diásporas en sus países receptores.

Frente a la complejidad que reviste tal situación, me propongo analizar las ambigüedades y contradicciones que se desprenden de esta clasificación en el ámbito legislativo provincial y los conflictos que se tejen en torno a esta activación patrimonial entre los agentes estatales y el pueblo mapuche. Intento demostrar que estas contradicciones son producto de -y moldean- la dinámica que ha adquirido en años recientes la relación entre el pueblo mapuche y los agentes estatales, a la vez que de ciertas directrices internacionales.In the past, the national/provincial&'s history and identity was shaped by refusing and/or rejecting differences, while inequity was hidden by claiming for a particular and homogeneous cultural unity: &"the criollismo&". Nowadays, the archaeological rests of indigenous past are re-categorized in Rio Negro`s legislation as a province`s cultural heritage. Considering the complexity of these circumstances, the purpose of this article is (to analyse the contradictions and ambiguousness released by this classification at the legislative context and the conflicts that this heritage activation weaves between the state`s agents and mapuche`s people. I will try to demonstrate that this contradictions are the product of -and also provide- the relationship between mapuche`s people, state`s agents and certain international directrices in recent years.

En nous intéressant d’abord au rapport à l’autre mis en place par le bavard lui-même, puis à la manière dont ce rapport à l’autre infléchit, obscurcit le texte et s’y figure, pour ensuite en venir à la position du lecteur empirique. En somme, Le Bavard ferait de nous des lecteurs parce qu’il interrompt la croyance à l’œuvre dans la lecture.The present article questions the mode of address used in Le Bavard. Can a “bavard”, a prattler, that, in several respects is a writer, address another, and in what circumstances? This address is determined by a relation to language, which is also the object of our investigation. We will first explore the relationship to the other established by the “bavard” himself, then the way in which this very relationship warps and obscures the text as it is reflected in it, and finally the position of the empirical reader. At the end of the day it is argued that Le Bavard turns us into readers because the text disrupts the belief that underlies the act of reading.En este artículo interrogamos el tipo de interpelación utilizado en Le Bavard (El Hablador. ¿Un hablador, es decir, desde otro punto de vista, un escritor, puede dirigirse al otro, y bajo qué condiciones ?

The analysis of this rate allows to portrait a more complete profile of those individuals who are more likely to either become unemployed or stay in such a situation. We find significant differences in the analysis of the unemployment rate and the incidence rate in Colombia, which suggests the importance of addressing certain elements underlying unemployment duration when appraising unemployment typology and policies aimed to overcome it.

    Full Text Available The Municipality of Bistriţa – a potential model for surpassing urban risks and for the touristic capitalisation of its historic center. Situated on the trail of an important trade route, exploiting from an early age its rich natural surroundings, Bistriţa has developed as a typical Transylvanian city. Its historic center, built during the XIV-XVII centuries, compact and uniform, is a valuable urban and architectural heritage and was declared a protected architectural area. In time, especially during 1948-1990, a series of urban risks affected Bistriţa’s historic center, due to the carelessness and ignorance towards the past and the area’s identity, which are highlighted in this study. After 1990, a beneficial process of restoring this heritage began, along with the awareness and the sense of ownership of the local community regarding its value and along with its capitalisation through tourism.

El artículo es producto de una investigación sobre las condiciones de implementación de la política educativa colombiana Programa Nacional de Bilingüismo. Para el estudio se empleó una encuesta que fue respondida por 70 administradores escolares de 46 instituciones educativas de la ciudad. Los resultados mostraron que el perfil típico del administrador escolar corresponde a mujeres entre los 50y 60 años que tuvieron contacto con el idioma inglés durante sus estudios de básica secundaria, tienen título de Especialización como máximo nivel de formación alcanzado y cuentan con experiencia profesional superior a 11 años. Se hallaron diferencias entre los sectores público y privado: en el primero los directivos tienen un nivel más alto de formación académica y mejores salarios. Los resultados sugieren que se necesita mayor apoyo a la formación de los directivos del sector privado y un mejor reconocimiento económico a la labor desempeñada por los directivos docentes en ambos sectores.

The Mann Whitney U test showed no differences between variables with respect to sex, we observed older children were more creative. The Kruskal -Wallis test reported significant differences amongst the three groups in creativity, task commitment, academic self-concept and teacher nomination. The Spearman correlation showed significant positive associations between age and creativity; and task commitment to academic self-concept. We conclude outstanding students are part of heterogeneous group, so it is necessary to evaluate them with different variables to determine their educational needs.

En secret, il rêve de mener une existence héroïque sur le modèle de Napoléon. Le rôle idéal de Napoléon et le rôle social de prêtre sont conçus comme contraires, mais peuvent, néanmoins, difficilement être séparés dans les actions concrètes de Julien. La présente étude porte sur la dialectique entre l'idéal de Napoléon et la réalité de prêtre, et s'inscrit tant dans les sciences littéraires que dans la théorie des rôles sociaux, avec le but d'intégrer la perspective de la sociologie ainsi que celle de l'anthropologie.In Le Rouge et le Noir erzählt Stendhal den sozialen Aufstieg des Kleinbürgersohns Julien Sorel in der Restaurationsgesellschaft. Julien ist ein Priesterschüler, der die Restaurationsgesellschaft und ihre Werte verachtet und heimlich eine napoleonische Heldenexistenz ersehnt. „Napoleon“ und „Priester“ werden in der literaturwissenschaftlichen Rezeption des Werkes dabei immer wieder als Rollen interpretiert. Diese beiden Rollen sind zwar konträr konzipiert, in Juliens Handlungen aber kaum voneinander zu trennen. Die Dialektik von Napoleon-Ideal und Priester-Realität wird hier mit Hilfe literaturwissenschaftlicher Rezeptionsansätze, sowie unter den soziologischen und  anthropologischen Perspektiven der Rollentheorie untersucht.

Potencialmente peligroso y despreciable, el estereotipo es fuente de cohesión social: cuando, privados de conocimientos empíricos, nos remitimos a fuentes de segunda mano y asimilamos imágenes de manera indiscriminada porque “así lo quiere la tradición”, apelamos al estereotipo, que nos conforta en la sensación de pertenecer a un cuerpo social solidario... y nos aleja del cuerpo. A nivel de los textos ocampianos, para que el estereotipo sea eficaz y logre hacer reír a pesar de la presencia obvia del horror (cuerpos deformes, crímenes, violaciones... debe poder ser reconocido por un público advertido. Sin embargo, el vértigo que produce la oscilación entre lo familiar y lo que “no soy yo” alcanzará probablemente también a un lector extranjero

    Full Text Available Obwohl Konstantin als der erste christliche Kaiser im Bewusstsein der Christen seit Jahrtunderten einen besonderen Platz eingenommen hat, sind dabei trotzdem einige nicht notwendig geringe Unterschiede zwischen der West- und Ostkirche zu beobachten. Die kommen symbolisch in der Tatsache zum Ausdruck, dass im Westen Konstantin niemals als Heiliger verehrt wurde, was auch die zu Teil stürmische Kritik an seine Person seit der Aufklärung erleichterte. Der Autor mochte in diesem Aufsatz die Frage beantworten, wie es mit dem Konstantinbild in der frühesten Geschichtsschreibung der Westkirche steht. Zu diesem Zweck analysierte er einige typische Konstantinstellen bei Laktanz, Hieronymus in seiner Chronik, Rufin von Concordia, Orosius und schliesslich auch das Konstantineulogium in De civitate Dei Augustins. Dabei zeigte sich, dass lediglich Rufin in seiner, von östlichen Einflussen stark geprägten Kirchengeschichte dem östlichen Eusebianischen Model treu folgte und den Kaiser in erster Reihe als vorbildlichen Christen, dem der Fortschritt des christlichen Glaubens alles bedeutet, schilderte. Alle andere herangezogenen Geschichtsschreiber zeigen zu Teil erhebliche Abweichungen davon, die meist auf Grund der kirchenpolitischen Zusammenhänge, in denen sie wirkten, verstanden werden können. Das trifft schon für das Konstantinbild bei Laktanz zu. Konstantin in De mortibus persecutorum ist zwar makellos und vom Anfang an ein grosser Befürworter des Christentums, muss sich jedoch auf Grund der frühen Entstehungszeit der Schrift unmittelbar nach der Konstantinischen Wende seinen erhobenen Platz mit seinem Mitkaiser Licinius teilen, was bei den Lesern aus den späteren Jahrhunderten für Verwirrung sorgte. Ganz anders stehen die Dinge bei Hieronymus. Er macht Konstantin für die Ausbreitung des Arianismus verantwortlich, was alle seine Erfolge überschattet und in einem düsteren Bild des ersten christlichen Kaisers resultiert, wobei alle seine problematischen Taten Erwähnung finden, sein Christentum dagegen kaum. Auch Orosius übernimmt die gerade erwähnten Taten in seine Erzählung, entschärft jedoch das negative Urteil des Hieronymus über Konstantin. Zugleich lässt er den Kaiser jedoch nicht nur weit hinter dem vorbildlichen Kaiser Theodosius, sondern auch hinter dem ersten römischen Kaiser Augustus stehen. Augustinus schliesslich betonte zu einem das Glück Konstantins in allen Bereichen, was er auf sein Christentum zurück führt, da er keine Götzen verehrt habe, was jedoch im krassen Gegensatz zu seiner Behauptung, das irdische Glück könne nicht als Massstab des christlischen Herrschers gelten, steht, und somit das Konstantineulogium wenigstens zweideutig erscheinen lässt.

    In the context of climate change, no one solution is future-proof. It is going to take a coordinated worldwide effort to find the right mix of energy policies while balancing diverse and sometimes competing priorities. The WLPGA Climate Change Working Group (CCWG) seeks to demonstrate that the technologies needed to continue current rates of development while mitigating climate change already exist and that LP gas can be a major part of today's solutions to this challenge. LP gas is not a zero-GHG fuel. However, in most cases it can make major and immediate contributions to delivering real GHG emissions reductions. In some ways LP Gas can claim to be ahead of its time, for its clean-burning, low-carbon advantage is available at once, so that even using today's technology, most industries can exceed Kyoto GHG reduction targets by switching to LP Gas. The fact is that LP Gas produces lower GHG emissions compared to conventional energy supplies in virtually every application it is used, from stationary applications such as water heating, space heating, cooking and industrial boilers to transportation applications. There are opportunities to switch to clean burning LP gas for virtually every industry as a means meet GHG targets. LP gas is also portable, making it a perfect complement to distributed renewable energy source such as solar, wind and wave energy (and soon the fuel cell), thereby reducing our reliance centrally produced electricity. LP Gas used in combination with these renewable sources also can improve energy reliability while reducing the overall life-cycle costs. The portable and clean burning nature of LP Gas also makes it an ideal substitute for solid fuels in domestic cooking and heating applications. Household solid fuel use, overwhelmingly concentrated in developing countries, accounts for up to 30% of black carbon emissions worldwide according to some statistics. Switching to LP Gas could lower global GHG emissions as well as help to diminish deforestation thus preserving the trees needed to maintain a global climatic equilibrium and combat climate change. When implementing climate change policies, every ton of GHG reduction helps, especially in the context of emissions trading. LP Gas offers a tremendous opportunity for a range of industries to meet or exceed their legislative requirements on GHG emissions, and it is widely available today. Policy-makers should consider LP gas when seeking a switch from business-as-usual energy solutions. The European Union (EU) is taking a world leadership towards sustainable (World Energy Technology Outlook), a 'Carbon Constraint Case' can lead to a future win-win solution: a strong reduction of CO{sub 2} emissions and the emergence of new and clean energy technologies. The way towards a post-carbon society is challenging. Technological developments are necessary but not sufficient. Socio-economic actions, market instruments and land use measures should also help to make the difference. (author)

    The STIC 2001 and STIC 2002 projects intend to allow the implementation and the assessment of Intensity Modulated Radiation Therapy in France. IMRT is an innovative technique in which the high-dose radiation volume conforms to an accurately defined target volume with less morbidity to the surrounding normal tissues. The main medical objectives of the projects are (1) to improve the therapeutic index while decreasing acute toxicity and late sequelae (mainly xerostomia and acute mucite for head and neck tumors), which allows an increase in the radiation dose to the tumor and then a better tumor control; (2) to propose a salvage treatment to patients who locally recurred in previously irradiated sites; (3) to determine the optimal treatment guidelines for a safe use of the technique in clinical routine. Our projects also aim at comparing IMRT and 3D conformal treatments on the one hand (STIC 2001), and IMRT and conventional treatments on the other hand (STIC 2002), with regard to costs. As a matter of fact, the use of IMRT is presently limited in France because its implementation requires high investment and personnel costs. The seventeen French Regional Cancer Centres involved in the two projects intend to study the additional cost of the use IMRT in comparison with the use of standard techniques, which appears to be a step for a wide use of this technique in France. Each of the studies is two-year prospective, and includes patients with head and neck tumors treated with a curative intend (post operative or exclusive treatments for STIC 2002 and STIC 2002), and patients with a prostate cancer (STIC 2001).

    In order to accomplish the task of supporting and ‘fostering’ human self-understanding, philosophy obviously has to deal with human psychology. The normative dimension of its results, though, depends on whether philosophy regards human psychology in an essentialist or in a historical way, that is, it depends on the anthropological assumptions constituting the background of its inquiry. Through his project of a ‘natural history of morals’, Nietzsche helps clarifying some issues ...

    Fukushima is the third major accident in the short history of civilian nuclear reactors. As the two previous ones, Three Mile Island and Chernobyl, it has delivered lessons which have to be learnt by governments, nuclear organizations and industry. Among them, the most important ones are the followings: - The past upgrades of the operating reactors against severe accidents has to be reassessed; - The requirements on the plant to sustain external hazards (earthquakes, flooding,...) has to be reviewed and improved in some cases; - Plants have to be tested against unrealistic situations to verify that no cliff edge effect can be expected; - The competence and the independence of the Safety Bodies have to be verified. The situation in the Fukushima reactors is not yet completely stabilized and it will take years before a return to normal life in the vicinity can take place; nevertheless, considering the size of the disaster, due to the exceptional magnitude of the earthquake and the height of the tsunami, the consequences of the nuclear part of the event are rather low: no casualty and limited risks of cancer for people in the future.

    Directory of Open Access Journals (Sweden)

    Estefanía Estévez

    2010-12-01

    Full Text Available Estudios previos han identificado dos subgrupos de víctimas de violencia escolar: víctimas sumisas y víctimas agresivas. Las víctimas sumisas se caracterizan por su retraimiento ante la situación de violencia, mientras que las víctimas agresivas presentan un comportamiento hostil combinado con la situación de victimización. El presente estudio se centra en el segundo subgrupo y tiene como objetivo analizar posibles factores influyentes en el proceso que conduce del estado de victimización a la implicación en conductas agresivas en la escuela. La asunción de partida se fundamenta en la teoría de Emler que sostiene que el sentimiento de indefensión producido por la situación de victimización, junto con la decepción en las figuras adultas de autoridad ante su fracaso en la protección esperada, generan en el adolescente la necesidad de buscar una reputación antisocial y no conformista que le permita defenderse de los ataques venideros. Para poner a prueba estas relaciones, se ha utilizado una muestra compuesta por 1.319 adolescentes de entre 12 y 16 años. Los análisis estadísticos mediante un modelo de ecuaciones estructurales muestran resultados en la línea de la argumentación de Emler. En la discusión se comentan las implicaciones prácticas de estos resultados

    Full Text Available This paper reviews the extent to which the development of instruments that implement the principle of mutual recognition of judicial decisions in criminal matters, particularly the European arrest warrant (EAW, may be considered valuable tools for effectively combating cross-border crime in the European Union. In addition, we assess how these policy orientations may or may not overcome the persistent mistrust and lack of confidence among the member states, while at the same time respecting human rights and civil liberties. In particular, this paper analyses:1. EU judicial cooperation in criminal matters: does it fight and prevent cross-border crime effectively in the EU? 2. The European arrest warrant – is it an improved method to replace extradition? Does the EAW provide a better solution to the practical complexities and difficulties that characterise the current extradition system? What are the inherent gaps in the proposed new surrender procedure under the EAW? 3. Does the EAW guarantee a good balance between efficiency and judicial protection of the individual’s fundamental rights? Does the Green Paper on procedural safeguards for suspect sand defendants in criminal proceedings throughout the EU provide the right way forward? Does the EAW involve a real risk to the legal position and human rights of suspected individuals? 4. What is the added value of EU judicial cooperation against cross-border crime?

    The many and always increasing applications of Atomic Energy for peaceful uses set many safety and security problems relatively to the workers, populations, and locating of the sites in general. A comparative study of the radiation hazards to which the people working in the 'Commissariat a l'energie atomique' installations were exposed during 1957 and the results obtained concerning individual and collective safety and security were extremely satisfactory owing to a continuous control and supervision. 2. However a few contamination and irradiation incidents - exposed subsequently as well as the way they were dealt with - show the necessity of a circumstantial regulation inside of an atomic center to establish the responsibility of the service in charge of the control of the radiation and the responsibility of the services using radioactive products with regard to contamination by radioactive materials. 3. Abstract of the different practical safety and security regulations concerning holding, manipulation, transport and stocking of radioactive materials. Pursuant to the recommendations of the International Commission on Radiologic Protection, the radioelements are classified according to the danger that can occur from them in comparison with the Pu with regard to: - radioactive noxiousness; specific activity per unit of mass; contamination hazards. 4. The service in charge of radiation protection plays the important part of a technical adviser for the construction of specialized laboratories and sees to the keeping of protection regulations. 5. Data essential to radiation protection are given to the people using radioactive materials; particularly: - a table of the radioisotopes and the hazards occurring from them; - radiation hazards regarding {gamma} ray emitted by irradiated Pu; - radiation hazards regarding {gamma} ray emitted by irradiated Th. 6. As the hazards occasioned by irradiated uranium have already been studied, the case of a low and total irradiation will only be considered with regard to recuperation of uranium after simple machining.

L'utilisation croissante de l'energie nucleaire sous toutes ses formes a des fins pacifiques pose des problemes de securite vis-a-vis des travailleurs, des populations et des sites en general. Une etude comparee des risques d'irradiation auxquels le personnel du Commissariat a l'Energie atomique (CEA) a ete expose au cours de l'annee 1957 et des resultats du controle des radiations par les moyens de detection collectifs ou individuels montre que les installations du CEA ont une influence negligeable sur la sante, en raison de la surveillance exercee. 2. Cependant, quelques incidents de contamination et d'irradiation - sommairement indiques ainsi que la maniere dont ils ont ete regles - rendent necessaire l'elaboration d'une reglementation precise definissant les responsabilites respectives, au sein d'un etablissement nucleaire, des services utilisateurs et du Service charge de la Protection contre les Radiations, en matiere de prevention de la contamination. 3.

    Full Text Available In this paper I would like to highlight the signifi cant architectural regularity which characterizes the pre-Roman archeological remains registered in Carthage. Despite having been repeatedly interpreted from a preconceived logical and spatial point of view, these remains allow us to set out that the Tyrian foundation was established in the Carthaginian peninsula according to a model that is referred to as per strigas in archaeological literature because it was documented better at the Archaic Greek colonies in Sicily. To defend this idea, I will indicate which architectonic remains make up its material basic, paying special attention to the remains found underneath the crossroads of the decumanus maximus and the cardo x-east, and I will try to summarize the state of the current issue on the urban shape of Phoenician Carthage. I will then go over several documentated examples of orthogonal land division in urban spaces from the Ancient Near East. This information will provide insight on the possible technical and practical context of Phoenician societies in the 9th and 8th centuries BC and, more specifically, the socio-political context of the Carthaginian founders. Finally, in light of these elements, I will put forward a proposal of a reconstruction of the urban layout of Phoenician Carthage as a whole.En este artículo quiero llamar la atención sobre la significativa regularidad arquitectónica que caracteriza los restos arqueológicos prerromanos registrados en Cartago. Pese a haber sido repetidas veces interpretados desde un prejuicio lógico-espacial, estos datos permiten proponer que la fundación tiria se implantó en la península cartaginesa según un modelo que, estando mejor documentado en las colonias arcaicas griegas de Sicilia, ha sido denominado per strigas por la historiografía arqueológica. Para defender esta tesis señalaré qué restos arquitectónicos le sirven de base material, con especial atención a los hallados bajo el cruce entre el decumano máximo y el cardo x este, e intentaré sintetizar el estado de la cuestión actual sobre la forma urbana de la Cartago fenicia. A continuación repasaré algunos ejemplos de segmentación ortogonal de espacios urbanos documentados en el Próximo Oriente antiguo. Ello nos ayudará a suponer cuál habría sido el contexto técnico y práctico en que vivieron las sociedades fenicias de los siglos IX-VIII a.C. y, más concretamente, el contexto sociopolítico de los fundadores de Cartago. Por último y a la luz de estos elementos, presentaré una propuesta de reconstrucción de la forma urbana de la Cartago fenicia.

Questi concetti sono collegati alle asserzioni Romantiche di identità tra popolo, nazione, lingua e letteratura (e dunque al momento storico che crea le condizioni per la nascita della letteratura comparata come disciplina, all’espansione rinascimentale delle lingue nazionali (momento in cui Pascale Casanova colloca la nascita dello spazio letterario internazionale, e all’affermarsi delle lingue volgari in epoca medievale.

    The program ''plastic photovoltaic solar cells'' was launched in june 2002 at LCOF (laboratory of functional organic components - CEA). The aim of this program is to show the feasibility of efficient organic photovoltaic cells. At the moment the most efficient organic cells reach a conversion rate of 3,5 % compared to the average value of 16 % for silicon cells. This program sets a term of 4 years to reach a conversion rate of 5 % and an operating life of 5000 hours. Plastics (or polymers) are less expensive than silicon, are available on an unlimited basis and are environment friendly. Plastics are easy to handle and a sole technology (serigraphy) is necessary for all the stages of the fabrication process of the organic cells: serigraphy technology is used for the deposition of the substrate, of the material in which the conversion takes place, and of the protective skin.

    Full Text Available Many have invoked the nihilism that is endemic of the age we call the anthropocene. Bernard Stiegler has articulated this sentiment by highlighting how anthropocene films are typically nihi listic, for example, Von Trier’s Melancholia. But if the age is characterized by a cultural pessi mism about the future of human kind, or again about its posthuman supersession, there is also a complementary symptom that corresponds to a strange optimism before the impasses of our age. This optimism, we find it represented in another anthropocene film: Nolan’s Interstellar. This too is a film where the protagonists are faced with a world lacking a future, a world dying under the stresses caused by the human’s exploitation of nature. Here, instead of the mantra ‘Enjoy it while it lasts’, an opposing moral is repeated: ‘Don’t go gentle into that good night, Rage, rage against the dying of the light.’ In the film, Thomas’ poem is a tribute to prometheanism; the death of the earth will not mean the end of human life, it declares, the human will surpass all the limits of its ecosystem, the constraints of space time itself, and become pure hyperdimensional intelligence. The film echoes the superstitious optimism in the promise of technology we now find at the heart of contemporary movements such as accelerationism. This paper assesses the validity of this intrumentalization of optimism, drawing from Leibniz’s concept of compossibility and the cosmological anthropic principle (observer bias.

    2009-10-01

    Full Text Available Las políticas educativas desarrolladas en el contexto del auge del neoliberalismo económico asumen una serie de efectos beneficiosos para el crecimiento económico y la igualdad de oportunidades educativas. Su hegemonía a lo largo de los últimos años, con un especial protagonismo del Banco Mundial, se ha traducido en su extensión en diversas partes del globo, y especialmente en los países en vías de desarrollo. Dichas políticas se presentan como respuesta a los retos de la globalización y como estrategia eficaz para asegurar beneficios colectivos del desarrollo educativo, especialmente para aquellos grupos socialmente más desfavorecidos. El artículo identifica las principales tesis de la política educativa neoliberal en el terreno de las relaciones entre educación y empleo, entre expansión educativa y gasto público y en las estrategias educativas de lucha contra la pobreza. Para cada una de ellas cuestiona los efectos esperados de las propuestas políticas hegemónicas y ofrece evidencias de resultados que muestran que en ningún caso los beneficiarios son los colectivos más desfavorecidos.In the context of economic neoliberalism, educational policies assume positive effects for both economic growth and equality of educational opportunities. In recent years, this thinking has been hegemonic: it has been extended around the world and especially in developing countries (with a special role of the World Bank. Those policies are presented as a response to the challenges of globalisation and as the correct strategy to ensure collective benefits of educational development, especially for socially disadvantaged groups. This paper identifies the main theses of neoliberal educational policy. The relationship of education and labor market, the connection between educational expansion and public expenditure and educational strategies to combat poverty are explored as some of the fields where neoliberal educational policies are produced. Expected effects of educational policy measures are questioned for each of these fields. At the same time, the text provides evidence of results that show that the most disadvantaged groups are not those that can really obtain the main benefits of mainstream educational policies.

    Full Text Available La probabilidad de que una persona mayor tenga que declarar como testigo o víctima de un atraco o un suceso similar aumenta en función de la esperanza de vida de la población. Por ello, resulta relevante conocer si las personas mayores producen testimonios menos exactos que los jóvenes, así como determinar cuáles son las circunstancias en las que pueden ser más proclives a cometer errores. En este estudio utilizamos una prueba de reconocimiento para analizar la memoria para las acciones de un atraco en adultos jóvenes y mayores. Aunque no hubo diferencias en los aciertos, las personas mayores cometieron una proporción superior de falsas alarmas y resultaron menos exactas que los jóvenes en el reconocimiento de las acciones del suceso. Además, las personas mayores tuvieron más dificultades que los jóvenes a la hora determinar el autor de las acciones correctamente reconocidas como pertenecientes al atraco. Por lo tanto, los déficits de las personas mayores en el control del origen de la información que recuerdan podrían ayudar a explicar la menor exactitud de su memoria para el suceso, un hallazgo especialmente relevante al tomar declaración a una persona de edad avanzada.

A secondary data analysis was performed to an epidemiological survey done in seven cities in Peru (Lima, Arequipa, Huamanga, Trujillo, Cuzco, Callao and Maynas. 6399 men and women participated, of whom 3909 participants declared living together with an intimate partner at the time of the interview. Univariate and multivariate logistic regression models were used to identify associated factors to the roles of victim or aggressor. Results. The likelihood of being aggressor or victim in cases of intimate partner physical violence was independent of sex (p<0,01 and the couple´s time living together. Factors associated to a higher probability of both roles included a history of exposure to physical violence during childhood, having a favorable attitude towards violence, heavy alcohol drinking, and being younger than 45 years, as well as having a monthly family income of less than 750 USD or an educational attainment of less than complete tertiary school. Geographically, Cusco was the city where it was most likely to find an aggressor or a victim of intimate partner physical violence. Most of these associations obtained p-values of less than 0.001. Conclusions. In cases of intimate partner physical violence, the pattern of predictors is similar in both roles, i.e., aggressor and victim. Sex and the couple´s span of time living together did not predict any of both roles.

  19. The Bi-Directional Prediction of Carbon Fiber Production Using a Combination of Improved Particle Swarm Optimization and Support Vector Machine

    Directory of Open Access Journals (Sweden)

    Chuncai Xiao

    2014-12-01

    Full Text Available This paper creates a bi-directional prediction model to predict the performance of carbon fiber and the productive parameters based on a support vector machine (SVM and improved particle swarm optimization (IPSO algorithm (SVM-IPSO. In the SVM, it is crucial to select the parameters that have an important impact on the performance of prediction. The IPSO is proposed to optimize them, and then the SVM-IPSO model is applied to the bi-directional prediction of carbon fiber production. The predictive accuracy of SVM is mainly dependent on its parameters, and IPSO is thus exploited to seek the optimal parameters for SVM in order to improve its prediction capability. Inspired by a cell communication mechanism, we propose IPSO by incorporating information of the global best solution into the search strategy to improve exploitation, and we employ IPSO to establish the bi-directional prediction model: in the direction of the forward prediction, we consider productive parameters as input and property indexes as output; in the direction of the backward prediction, we consider property indexes as input and productive parameters as output, and in this case, the model becomes a scheme design for novel style carbon fibers. The results from a set of the experimental data show that the proposed model can outperform the radial basis function neural network (RNN, the basic particle swarm optimization (PSO method and the hybrid approach of genetic algorithm and improved particle swarm optimization (GA-IPSO method in most of the experiments. In other words, simulation results demonstrate the effectiveness and advantages of the SVM-IPSO model in dealing with the problem of forecasting.

In this study, we present a preclassification and later regression based method optimized by improved particle swarm optimization (IPSO for sales growth rate forecasting. We use support vector machine (SVM as a classification model. The nonlinear relationship in sales growth rate forecasting is efficiently represented by SVM, while IPSO is optimizing the training parameters of SVM. IPSO addresses issues of traditional PSO, such as relapsing into local optimum, slow convergence speed, and low convergence precision in the later evolution. We performed two experiments; firstly, three classic benchmark functions are used to verify the validity of the IPSO algorithm against PSO. Having shown IPSO outperform PSO in convergence speed, precision, and escaping local optima, in our second experiment, we apply IPSO to the proposed model. The sales growth rate forecasting cases are used to testify the forecasting performance of proposed model. According to the requirements and industry knowledge, the sample data was first classified to obtain types of the test samples. Next, the values of the test samples were forecast using the SVM regression algorithm. The experimental results demonstrate that the proposed model has good forecasting performance.

Un conjunto importante de variables (cuantificables y cualitativas fueron puestas en diálogo activo con numerosas y variadas fuentes de información de diversa procedencia. Las conclusiones se orientan a mostrar que, a comienzos del siglo XX, Entre Ríos estaba encaminado indudablemente en la sociedad escriturada, pero gran parte de sus habitantes no tenían acceso a la lectura. Existían importantes esfuerzos para la producción de textos escritos (periódicos, revistas, propagandas aunque muchos de sus destinatarios sólo podían acceder a ellos a través de otros lectores o decodificar las imágenes -en caso de haberlas-. Mercado creciente para la producción y circulación de bienes de lectura, pero de límites precisos con insuficiente consistencia para poder mantenerlo.

    Full Text Available El objetivo de la investigación fue la adaptación al español de las escalas de interés y comportamientos generativos de McAdams, así como el estudio de la generatividad en la vejez y su relación con el bienestar. La muestra estuvo compuesta por 165 voluntarios mayores de 65 años que, además de las versiones españolas de las escalas de generatividad, completaron instrumentos para evaluar satisfacción con la vida y orientación al futuro. Los resultados indicaron que la fiabilidad de las versiones españolas de las escalas de generatividad fue aceptable y similar a las originales en inglés. Mientras el interés generativo se relacionó con la satisfacción con la vida, los comportamientos generativos no lo hicieron. Sin embargo, ambas escalas sí se relacionaron con la orientación al futuro, aunque esta relación no se confirmó en un análisis multivariable. Los resultados resaltan la importancia de la generatividad en la vejez y de distinguir entre interés y acción generativa, ya que sus beneficios podrían ser muy diferentes.

    Fusobacterium nucleatum is present in colon cancers where it was shown to generate a proinflammatory microenvironment that supports colorectal neoplasia progression. Remarkably, alongside with proinflammatory stimulation, fusobacteria also inhibit cytotoxicity of immune cells. Thus, it appears as if tumors exploit fusobacteria to generate a favorable proinflammatory and anti-cytotoxic microenvironment.

    Full Text Available On the 11th of January 2015, France experienced its largest demonstration since World War Two, in the aftermath of the terrorist attacks against Charlie Hebdo and the Hyper Casher supermarket. Rapidly though the profiles and motivations of the participants to the rallies were questioned. Were they “good citizens” marching in defense of freedom of expression, tolerance and republican values? Or were they actually expressing their rejection of Islam and Muslims, as suggested by the demographer Emmanuel Todd (2015? To answer these questions this article takes a social movement approach and draws from the data of a national opinion poll conducted two months after the attacks. First, the results show that the “Charlie” in the streets had the usual profile of demonstrators mobilized on post-materialist issues: They were overrepresented among young, urban, educated, leftwing, and tolerant citizens. Second, they highlight the importance of the religious factor: Muslims were less inclined to say they had participated to the rallies, and practicing Catholics to say they wished they had. Last, they show that terrorism does not automatically trigger an authoritarian dynamic, on the contrary. Its effects depend on how the issue is framed in social and political discourses.    Résumé Le 11 janvier 2015, les attentats contre Charlie Hebdo et l’Hyper Casher ont suscité les plus grandes manifestations que la France ait connues depuis la Seconde Guerre mondiale. Assez vite cependant le profil et les motivations des manifestants ont été mis en cause. S’agissait-il de “bons citoyens” marchant pour la défense de la liberté d’expression, de la tolérance et des valeurs républicaines? Ou n’exprimaient-ils pas plutôt leur rejet de l’Islam et des Musulmans, comme le suggérait le démographe Emmanuel Todd (2015? Pour répondre à ces questions cet article, inscrit dans la sociologie des mouvements sociaux, s’appuie sur les données d’une enquête nationale par sondage conduite deux mois après les attentats. Les résultats montrent, d’abord, que les manifestants pro “Charlie” avaient le profil habituel des manifestants mobilisés pour des causes post-matérialistes : surreprésentation des citoyens jeunes, urbains, instruits, de gauche et tolérants. Ensuite ils soulignent l’importance du facteur religieux. Les Musulmans ont été moins enclins à dire qu’ils avaient manifesté, et les Catholiques pratiquants à dire qu’ils auraient souhaité le faire. Ils montrent enfin que le terrorisme ne déclenche pas automatiquement une dynamique autoritaire, au contraire. Tout dépend de la manière dont le problème est cadré dans les discours socio-politiques.

En primer lugar, la denominada escuela preterista albergaría a aquellos autores que encajan el libro en un período ya pasado. De acuerdo con esta interpretación, que casi ha gozado de un carácter oficial en ciertos medios católicos, sostenida entre otros por el jesuíta Alcázar en 1614, el Apocalipsis describiría la historia de la iglesia desde el siglo primero hasta el triunfo en la época de Constantino.

    Drying refers to the removal of water from solid materials and tends to cover processes such as filtration, heat removal of humidity and even sublimation. It is probably the most energy intensive operation in industry, consuming nearly 8.4% of all the energy used by Canadian industry. This datum applies to a vast gamut of technologies and techniques for drying products in the form of solid particles, pastes, slurries or solutions. The CANMET Energy Diversification Laboratory developed a new type of dryer for the dewatering of solid particles: the pulsed-fluidized bed dryer. The new technology is described as well as its performance and advantages. In the course of the last four years, the laboratory transferred Polish technology and modified it for high temperature operation. The laboratory obtained a patent for the modified technology and negotiated a licence with Barr-Rosin Inc. for the manufacturing and commercialization of pulsed-fluidized bed dryers. Given the numerous advantages of the technology, and economic and technical planning, the laboratory foresees a vast gamut of uses for the future. 3 refs.

    Full Text Available This article addresses a key issue during the course of Mexico's 2006 presidential campaign: How did markets react to changes in support for the left-leaning Andrés Manuel López Obrador (PRD? To answer this question, I develop a series of alternative arguments for how investors would respond changes in PRD support during the campaign. I evaluate the arguments using a times series GARCH model.The results show that changes in the levels of support for the candidate did not affect market returns but they did affect market volatility. Increased electoral uncertainty as margins narrowed, raised market volatility, while increasing electoral certainty regardless of whether rises in support were for López Obrador or the market-friendly Felipe Calderón (PAN, reduced it. This finding reveals that investors may have accepted the prospect of a López Obrador presidency ahead of the election but not the possible post-election social and political instability associated with a tight race.

    Full Text Available Los datos existentes sobre la indicación y el momento de inicio del soporte nutricional en pacientes críticos no son homogéneos. No obstante, la presencia de deterioro en la situación nutricional se acompaña de efectos perjudiciales por lo que, en líneas generales, sería recomendable el inicio de soporte nutricional especializado si es presumible un periodo de ayuno superior a 5-7 días. La nutrición parenteral administrada rutinariamente a los pacientes críticos puede incrementar su morbi-mortalidad. En los casos en los que sea posible, la nutrición enteral debe ser la vía de aporte preferente de nutrientes, dado que con ello se ha descrito un efecto favorable sobre la tasa de complicaciones infecciosas. La nutrición enteral debería iniciarse de forma precoz (dentro de las primeras 36 horas de ingreso. No obstante, si bien la administración transpilórica de nutrientes podría reducir la broncoaspiración e incrementar el volumen eficaz de dieta recibido por los pacientes, no existen datos para recomendar el uso rutinario de la vía transpilórica para el soporte nutricional en los pacientes críticos.Existing data about indication and time of onset of nutritional support are not homogeneous. However, the presence of a deterioration of the nutritional status is accompanied by harmful effects so that, broadly speaking, specialized nutritional support onset would be advisable if a fasting period longer than 5-7 days is foreseen. Parenteral nutrition routinely administered to critically ill patients may increase their morbidity and mortality. Whenever possible, enteral nutrition should be the preferred route of nutrients intake since it has been shown to have a favorable effect on infectious complications rates. Enteral nutrition should be started early on (within the first 36 hours of admission. Although transpyloric nutrients administration may however reduce broncho-aspiration and increase the diet effective volume received by patients, there are no data for recommending routinary usage of the transpyloric route for nutritional support in the critically ill patients.

    Full Text Available This paper purposes to argue with Paul Ricoeur's interpretation accordingto which a narrative concept of identity may be found in Hannah Arendt's works. Firstly, Arendt's peculiar fragmentary nature of narration will be studied. Secondly, the connection between identity and speech depicted by Arendt will be emphasized on, thus allowing for an articulation of a not necessarily narrative character. Finally, it shall be considered that identity has a phenomenological dimension in Arendt, manifest in the fact that theÿ'who' appears andUNLPshows itselfÿonly to others.ÿThese singularities of Arendt's approach are in turn clarified in relation to Walter Benjamin's concept of history and his notion of dialectical image

    A study was conducted with a view to determining the steps to be taken in order to control the Bacharach opacity of smoke released by different types of engines powered by fuel oil through the same chimney. A statistical model was constructed to relate Bacharach opacity to the operational parameters of the burning equipment on the basis of information recorded during its routine functioning over a period of about one year, with no laboratory experiments nor intentional alteration of such parameters. Different chemo-metric tools were applied to the data recorded over a period long enough to ensure a good model. Owing to the high complexity of the data handled (equipment parameters, fuel oil properties, operating conditions, etc.), the model was constructed by using different tools that were tested in order of increasing complexity. Thus, a Principal Component Analysis (PCA) was initially conducted on the variables defining the different types of fuel oil used in order to suppress their high correlation. The scores obtained from this analysis were used as the fuel data in the subsequent steps. Owing to the high complexity of the parameters involved, linear regression methods were not functional, so the non-linear regression method Alternating Conditional Expectations (ACE) had to be used instead to determine the influence of these parameters on Bacharach opacity. After the model was constructed, the parameters that govern opacity were determined and the model was experimentally validated by exploring the variables that can be modified at plant level (viz. the combination of conradson coke and asphaltenes in the fuel, the oil viscosity at burner and the proportion of oxygen in the furnace). Changes in these variables were found to alter the properties of the stack; also, the predictions of the ACE model were confirmed. Consequently, the proposed methodology allows the effective control of smoke released by the equipment. (authors)

Active actors favoring smoking in Spain were identified and classified according to their characteristics, the sphere in which they act, and their preferred territorial arena. Results: We identified tobacco companies (Altadis and Philip Morris dominate the market, tobacco trade organizations (tobacconists, front-line organizations created by the tobacco industry (The Smokers for Tolerance Club, organizations of tobacco growers, and processing companies. Distribution to retailers is dominated by Logista, owned by Altadis. Other sectors to take into account are vending companies and those manufacturing related products (cigarette paper, matches or lighters. The contacts of these actors with the public administration are reviewed, notable among which are the role of the Commissioner for the Tobacco Market, the Ministry of Agriculture, the Ministry of Finance and the Ministry of the Economy. Ties were also found with employers' organizations, some political parties, and unions, as well as with other sectors with social influence such as the media and advertising sectors. Conclusions: The map of actors favoring smoking in Spain is complex and goes beyond the confines of the tobacco industry. Understanding this web is crucial to promoting comprehensive prevention policies.

    To determine factors that may predict intestinal pseudo-obstruction (IpsO) in systemic lupus erythematosus (SLE) patients complicated by digestive manifestations. SLE patients with digestive manifestations (n = 135) were followed at Southern Medical University affiliated Nanfang Hospital from 2000 until 2013. Demographic variables, clinical features, and laboratory data were compared between the two groups. Univariate and multivariate logistic regression models were used to establish factors that predispose to IpsO in these patients. At the end of the study period, 32 (23.7%) patients had developed IpsO. Mortality (9 patients) was infrequent and the cause of death was unrelated to IpsO. Independent predictors of IpsO in SLE were ureterectasia, anti-U1 RNP(+), peritonitis, and low C3 levels. Regular abdominal X-ray examinations are recommended in SLE patients with ureterectasia, anti-U1 RNP(+), peritonitis, or low C3 levels, as early diagnosis and therapy may prevent unnecessary surgical intervention and improve the disease course. © The Author(s) 2015.

    Full Text Available Making full use of abundant renewable solar energy through the development of photovoltaic (PV technology is an effective means to solve the problems such as difficulty in electricity supply and energy shortages in remote rural areas. In order to improve the electricity generating efficiency of PV cells, it is necessary to track the maximum power point of PV array, which is difficult to make under partially shaded conditions due to the odds of the appearance of two or more local maximum power points., In this paper, a control algorithm of maximum power point tracking (MPPT based on improved particle swarm optimization (IPSO algorithm is presented for PV systems. Firstly, the current in maximum power point is searched with the IPSO algorithm, and then the real maximum power point is tracked through controlling the output current of PV array.,. The MPPT method based on IPSO algorithm is established and simulated with Matlab / Simulink, and meanwhile, the comparison between IPSO MPPT algorithm and traditional MPPT algorithm is also performed in this paper. It is proved through simulation and experimental results that the IPSO algorithm has good performances and very fast response even to partial shaded PV modules, , which ensures the stability of PV system.  

  15. Improved Particle Swarm Optimization for Global Optimization of Unimodal and Multimodal Functions

    Particle swarm optimization (PSO) performs well for small dimensional and less complicated problems but fails to locate global minima for complex multi-minima functions. This paper proposes an improved particle swarm optimization (IPSO) which introduces Gaussian random variables in velocity term. This improves search efficiency and guarantees a high probability of obtaining the global optimum without significantly impairing the speed of convergence and the simplicity of the structure of particle swarm optimization. The algorithm is experimentally validated on 17 benchmark functions and the results demonstrate good performance of the IPSO in solving unimodal and multimodal problems. Its high performance is verified by comparing with two popular PSO variants.

    Aryl boronic acids or pinacol esters containing EDG were converted in good yields and fast reactions to the corresponding aryl fluorides using the readily obtainable solutions of AcOF. In reactions with aryl boronic acids containing EWG at the para position, there are two competing forces: one directing the fluorination to take place ortho to the boronic acid and the other, toward an ipso substitution. With EWG meta to the boronic acid, substitution ipso to the boron moiety takes place in good yields.

    The unexpected ability of arylzinc reagents bearing electron-donating substituents to react in a Friedel-Crafts fashion (cine) with electrophiles like perpivaloylated glucoside bromide and benzhydryl bromides in competition with organometallic coupling (ipso) is shown. The stereoelectronic factors required to promote the cine reactivity versus the classical ipso, and the mechanism of this alternative pathway, have been investigated. The Wheland intermediate is deprotonated intramolecularly in a 1,2-shift but also in a longer-range shift, leaving in this case the C-Zn untouched. In the latter case, it is possible to take advantage of this result for further functionalization.

  8. An Optimized K-Harmonic Means Algorithm Combined with Modified Particle Swarm Optimization and Cuckoo Search Algorithm

    Full Text Available Among the data clustering algorithms, k-means (KM algorithm is one of the most popular clustering techniques due to its simplicity and efficiency. However, k-means is sensitive to initial centers and it has the local optima problem. K-harmonic-means (KHM clustering algorithm solves the initialization problem of k-means algorithm, but it also has local optima problem. In this paper, we develop a new algorithm for solving this problem based on an improved version of particle swarm optimization (IPSO algorithm and KHM clustering. In the proposed algorithm, IPSO is equipped with Cuckoo Search algorithm and two new concepts used in PSO in order to improve the efficiency, fast convergence and escape from local optima. IPSO updates positions of particles based on a combination of global worst, global best with personal worst and personal best to dynamically be used in each iteration of the IPSO. The experimental result on five real-world datasets and two artificial datasets confirms that this improved version is superior to k-harmonic means and regular PSO algorithm. The results of the simulation show that the new algorithm is able to create promising solutions with fast convergence, high accuracy and correctness while markedly improving the processing time.

  11. An improved PSO algorithm for generating protective SNP barcodes in breast cancer.

    Directory of Open Access Journals (Sweden)

    Li-Yeh Chuang

    Full Text Available BACKGROUND: Possible single nucleotide polymorphism (SNP interactions in breast cancer are usually not investigated in genome-wide association studies. Previously, we proposed a particle swarm optimization (PSO method to compute these kinds of SNP interactions. However, this PSO does not guarantee to find the best result in every implement, especially when high-dimensional data is investigated for SNP-SNP interactions. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we propose IPSO algorithm to improve the reliability of PSO for the identification of the best protective SNP barcodes (SNP combinations and genotypes with maximum difference between cases and controls associated with breast cancer. SNP barcodes containing different numbers of SNPs were computed. The top five SNP barcode results are retained for computing the next SNP barcode with a one-SNP-increase for each processing step. Based on the simulated data for 23 SNPs of six steroid hormone metabolisms and signalling-related genes, the performance of our proposed IPSO algorithm is evaluated. Among 23 SNPs, 13 SNPs displayed significant odds ratio (OR values (1.268 to 0.848; p<0.05 for breast cancer. Based on IPSO algorithm, the jointed effect in terms of SNP barcodes with two to seven SNPs show significantly decreasing OR values (0.84 to 0.57; p<0.05 to 0.001. Using PSO algorithm, two to four SNPs show significantly decreasing OR values (0.84 to 0.77; p<0.05 to 0.001. Based on the results of 20 simulations, medians of the maximum differences for each SNP barcode generated by IPSO are higher than by PSO. The interquartile ranges of the boxplot, as well as the upper and lower hinges for each n-SNP barcode (n = 3∼10 are more narrow in IPSO than in PSO, suggesting that IPSO is highly reliable for SNP barcode identification. CONCLUSIONS/SIGNIFICANCE: Overall, the proposed IPSO algorithm is robust to provide exact identification of the best protective SNP barcodes for breast cancer.

    Full Text Available Riders to the Sea: An opera in one act based on the play by John Millington Synge, Ralph Vaughan Williams’s fifth opera, composed between 1925 and 1932, after The Poisoned Kiss (A Romantic Extravaganza, was first performed at London’s Royal College of Music on December 1st, 1937, with Malcolm Sargent conducting. A masterpiece of poetic intensity and a compendium of pain and quiet, resigned courage, worthy of a Greek tragedy, the Irish dramatist’s play was faithfully adapted by the composer-librettist in a work whose originality and universal message cannot fail to impress. Originating in his wide-ranging imagination―humanistic, brotherly, idealistic, universal―it speaks of a voyage of initiation to the Aran Islands, off the west coast of Ireland. The composer, inspired by folk wisdom and the world of the Spirit, open to worldly solicitations as well as to meditation, saw the play as a vehicle to highlight some aspects of his own musical heritage. In a few pages of dialogue, the score conveys a whole range of different emotions arising from the confrontation with Nature, and more particularly, from the forlorn struggle of the islanders against the sea and God, their ruler.

After the strike ended the employers went to the Labor Court. Proving the strike to be illegal resulted in the production of much documentary evidence, used here as a historical source. As a phenomenon, the strike, which marks the end of a cycle of strikes in the post-war years, also has aspects related to the 1945-1964 period in Brazil (and later. The way it was treated by the Labor Court shows how the political system, in dealing with the labor movement, sought to minimize its fears and tensions by containing the insinuations of workers as a social class, in a scenario whose democratic content strongly demanded the end of the Estado Novo dictatorship.

Discussions about the Regulation of assisted reproductive techniques in ColombiaThe recent concern for the normative regulation of assisted reproduction techniques (ART, raises discussions about how to manage the embryos, how many times to use a sample, how to define parenthood, and other issues. However, it has not been questioned who would be favouredwith these regulations and what is their contribution to social equity and development for an entire country. Considering that the urgency to guarantee the sexual and reproductive rights —theoretical framework invoked to require ART— should be aimed at reaching a fair society.The proposed analysis will be undertaken considering the case of applying the ART for surrogate mothers in Colombia. The paper presents the context in which it is intended to apply the normative regulation, alongside the review of some conceptual and empirical contributions by Michael Sandel concerning trends in surrogate motherhood among «developed» and «third world» countries. This should allow considering the profiles of fertility in Colombia as a sign of inequality in our country.Subsequently, we will approach the current legal discussion in Colombia concerning surrogate motherhood, from the only case of surrogate motherhood resolved by the Colombian Constitutional Court and the bill projects presented in the Colombian Congress to regulate this issue. Finally,we will present some reflections and discussion on the normative regulation of the ART and surrogate gestation, and the law as a transmission belt of varied interests, that is, that it ought to lead to common good, solidarity and cooperation, and not simply function as a regulator that ensures the fulfilment of contracts.

    Full Text Available The purpose of this paper is to better know how adult grand-children perceive their family history when their grand-parents have gone through major ordeals such as Holocaust and exile; what consequences these events and the way they have been transmitted have on their sense of identity and on their choices in their life. The grandchildren show a great diversity in the way they perceive their family history, their heritage, their identity, and they build their own life.

    The electricity sector has experienced a slow evolution. Renewable production developments and telecommunications and computers usage will bring major changes with hard to predict effects. Computerized management of production and local storage combined to a certain mastering of the allowed consumption by home automation could improve reliability and the final price for consumers. This change offers great opportunities but also risks of failures, both financial and technical. The regulators have a major role to play in order to understand the concrete gains of the technological propositions and to regulate the investment costs involved. [French] Le secteur de l'electricite a connu une evolution lente.

    The conference was related with some of the major questions concerning global energy governance today, the role of the different international organizations dealing with energy, the rules of the game between market and state players, the efforts to deal with climate change, and the integration of emerging countries in global energy governance, the roles of the different international organizations dealing with energy (will we see further fragmentation or more cooperation between them?). Tatsuo Masuda in his contribution discussed global energy governance from an oil perspective. Andre Mernier noted the particular nature of the Energy Charter, which, as it is founded upon an international treaty, is unlike other organizations in being legally binding. The legal basis of the organization means that agreements are especially powerful. Then Richard H. Jones underlined that last summer's volatility in oil markets, the ensuing financial and economic crisis, the major disruption in gas supplies to European markets this winter and the upcoming climate change negotiations have led to increasing calls for a stronger global dialogue on energy issues. This dialogue should deal with prices and investment, energy security and climate change

    As the reactors supplying the world production of radioelements for medical use have over 40 years of operation, the nuclear safety authority alerts the stake holders on the necessity to prevent the conflicts between public health and nuclear safety in the production of these elements; Asn estimates that the solution is not to extend the lifetime of the reactors but goes for a new international concerted approach. The most of the present production comes from five old reactors: N.R.U. at Chalk river (Canada, 40%), H.F.R. at Petten (Netherlands, 30%), Safari at Pelindaba (South Africa, 10%) B.R.2 at Mol (Belgium, 9%) and Osiris at Saclay (France, 5%). In this context, Asn organised in january 2009 a seminar on the safety-availability of facilities of radio-isotopes production with safety authorities of the concerned countries. Nea organised a seminar on the radiopharmaceuticals supply at the end of january 2009. (N.C.)

    2016-07-01

    This paper presents the first hardware implementation of neuro-fuzzy system (NFS) with its metaheuristic learning ability on field programmable gate array (FPGA). Metaheuristic learning of NFS for all of its parameters is accomplished by using the improved particle swarm optimization (iPSO). As a second novelty, a new functional approach, which does not require any memory and multiplier usage, is proposed for the Gaussian membership functions of NFS. NFS and its learning using iPSO are implemented on Xilinx Virtex5 xc5vlx110-3ff1153 and efficiency of the proposed implementation tested on two dynamic system identification problems and licence plate detection problem as a practical application. Results indicate that proposed NFS implementation and membership function approximation is as effective as the other approaches available in the literature but requires less hardware resources.

The T-S CIN is built through the combination of cloud model and T-S fuzzy neural network. Moreover, the IPSO algorithm employs parameter automation adjustment strategy and velocity resetting to significantly improve the performance of basic PSO algorithm in global search and fine-tuning of the solutions, and the flowchart of proposed approach is designed. Furthermore, some simulation examples are carried out and comparison results indicate that the proposed method is feasible, efficient, and is outperforming others. Finally, an industrial application example of coal mining face is demonstrated to specify the effect of proposed system.

    2004-01-01

    Optimising the major next-generation cosmological surveys (such as SNAP, KAOS etc...) is a key problem given our ignorance of the physics underlying cosmic acceleration and the plethora of surveys planned. We propose a Bayesian design framework which (1) maximises the discrimination power of a survey without assuming any underlying dark energy model, (2) finds the best niche survey geometry given current data and future competing experiments, (3) maximises the cross-section for serendipitous discoveries and (4) can be adapted to answer specific questions (such as `is dark energy dynamical?'). Integrated Parameter Space Optimisation (IPSO) is a design framework that integrates projected parameter errors over an entire dark energy parameter space and then extremises a figure of merit (such as Shannon entropy gain wich we show is stable to off-diagonal covariance matrix perturbations) as a function of survey parameters using analytical, grid or MCMC techniques. IPSO is thus a flexible, model-independent and scal...

First, the input features symbolizing the transient stability of power systems are extracted from synchronized measurements. Then, an ELM classifier is employed to build the TSP model. And finally, the optimal parameters of the model are optimized by using the improved particle swarm optimization (IPSO algorithm. The novelty of the proposal is in the fact that it improves the prediction performance of the ELM-based TSP model by using IPSO to optimize the parameters of the model with synchrophasors. And finally, based on the test results on both IEEE 39-bus system and a large-scale real power system, the correctness and validity of the presented approach are verified.

    A novel method for the prediction of RNA secondary structure was proposed based on the particle swarm optimization(PSO). PSO is known to be effective in solving many different types of optimization problems and known for being able to approximate the global optimal results in the solution space. We designed an efficient objective function according to the minimum free energy, the number of selected stems and the average length of selected stems. We calculated how many legal stems there were in the sequence, and selected some of them to obtain an optimal result using PSO in the right of the objective function. A method based on the improved particle swarm optimization(IPSO) was proposed to predict RNA secondary structure, which consisted of three stages. The first stage was applied to e ncoding the source sequences, and to exploring all the legal stems. Then, a set of encoded stems were created in order to prepare input data for the second stage. In the second stage, IPSO was responsible for structure selection. At last, the optimal result was obtained from the secondary structures selected via IPSO. Nine sequences from the comparative RNA website were selected for the evaluation of the proposed method. Compared with other six methods, the proposed method decreased the complexity and enhanced the sensitivity and specificity on the basis of the experiment results.

    A precise predictive model is needed to obtain a clear understanding of the changing dissolved oxygen content in outdoor crab ponds, to assess how to reduce risk and to optimize water quality management. The uncertainties in the data from multiple sensors are a significant factor when building a dissolved oxygen content prediction model. To increase prediction accuracy, a new hybrid dissolved oxygen content forecasting model based on the radial basis function neural networks (RBFNN) data fusion method and a least squares support vector machine (LSSVM) with an optimal improved particle swarm optimization(IPSO) is developed. In the modelling process, the RBFNN data fusion method is used to improve information accuracy and provide more trustworthy training samples for the IPSO-LSSVM prediction model. The LSSVM is a powerful tool for achieving nonlinear dissolved oxygen content forecasting. In addition, an improved particle swarm optimization algorithm is developed to determine the optimal parameters for the LSSVM with high accuracy and generalizability. In this study, the comparison of the prediction results of different traditional models validates the effectiveness and accuracy of the proposed hybrid RBFNN-IPSO-LSSVM model for dissolved oxygen content prediction in outdoor crab ponds.

    Full Text Available En el texto se problematizará la inclusión del género en psicología a partir de las construcciones discursivas obtenidas en una investigación cualitativa sobre las opiniones de estudiantes, profesores y profesionales. Dado que la mayor aceptación asimila "género" a "diferencia sexual" desde la tradición positivista y dualista, se neutraliza su capacidad transformadora. Esta versión "descomprometida" del género, se disocia discursivamente del feminismo social y las epistemologías feministas que generan mayores resistencias y temores. Tal y como argumentaré, una psicología positivista con su supuesta neutralidad y objetividad así como la permanencia de un imaginario androcéntrico y etnocéntrico dificultan la capacidad de cuestionar una psicología poco sensible a las relaciones de poder. Finamente, propongo la necesidad de combinar un análisis del currículo oculto con una comprensión de las argumentaciones y creencias que forman parte de la vida cotidiana del ejercicio y docencia de la psicología. Así se pueden retomar de forma conjunta los mecanismos de (reproducción y difusión de la ciencia con las relaciones e interacciones académicas y profesionales marcadas por el sistema sexo-género, que operan de forma compleja en las combinaciones de ciencia e ideología o discurso y acción.This text provides a discussion on the inclusion of gender in psychology from the discoursive constructions obtained in a qualitative investigation about students', teachers' and professionals' opinions. Since most people who support this idea relate "gender" to "sexual difference", based on to the positivist and dualistic tradition, its capacity of transformation is neutralized. In discoursive terms, this "uncommitted" version of gender is dissociated from social feminism and the feminist epistemologies that generate great resistance and fear. As it will be explained, a positivist kind of psychology with supposed neutrality and objectivity, as well as the continuous character of an androcentric and ethnocentric imaginary field, makes it difficult to question a kind of psychology that is little sensitive to power relations. Finally, there is a proposal of combining the analysis of a hidden curriculum with the understanding of argumentation and beliefs that consist part of everyday teaching and working with psychology. This way, it is possible to resume the mechanisms of science (reproduction and diffusion with the academic and profesional relations and interactions that are characterized by the sex-gender system and operate discourse and action in a complex way, in the combinations of science and ideology.

    Full Text Available Following the Charlie Hebdo terrorist attack that happened on January 7th 2015, around 4 million people gathered all over France in a rally of national unity. Soon, however, critics argued that those who participated to the rallies publicly displayed antiracist attitudes, but were driven by implicit prejudice toward Muslims. Our study addresses the question of whether implicit prejudice measured at the city-level can predict participation rates observed in these cities. We used data from the French/Arab IAT of the Project Implicit collected from 2007 to 2014 on the French territory (n = 3365, 35 cities and computed mean IAT scores for each city. We then tested whether the IAT scores predicted the participation rate observed in each city. In sharp contrast with the idea that Charlie Hebdo marchers were implicitly biased against Muslims, we found that cities implicitly biased against Arabs (as compared with French participated less, and not more, to the Charlie Hebdo rallies. These results also show, for the first time, that the level of implicit prejudice measured at the city-level, sometime several years before an event (2007, can predict large scale social behaviors. Résumé Suite aux attentats de Charlie Hebdo du 7 janvier 2015, plus de 4 millions d’individus se sont rassemblés en France dans un élan d’unité nationale. Rapidement, des critiques ont émergé, soutenant que même si les manifestants ont affiché des attitudes ouvertement antiracistes, ils étaient en fait motivés par des préjugés implicites vis-à-vis de la population musulmane. Notre étude traite la question de savoir si les préjugés implicites mesurés au niveau d’une ville peuvent prédire les taux de participation aux manifestations dans chacune de ces villes. Pour cela, nous avons utilisé les données issues de l’IAT Français/Maghrébins du 'Project Implicit' collectées en France entre 2007 et 2014 (N = 3365, 35 villes et calculé un score IAT moyen pour chaque ville. Nous avons ensuite testé si ces scores IAT permettaient de prédire le taux de participation observé dans chaque ville. Contrairement à l’idée que les « manifestants Charlie Hebdo » aient été poussés par des préjugés implicites vis-à-vis des musulmans, nous avons observé que les villes les plus biaisées à l’encontre du groupe « Maghrébins » (en comparaison au groupe « Français » ont moins, et non pas davantage, participé aux manifestations Charlie Hebdo. Ces résultats montrent également, pour la première fois, que le niveau de préjugés implicites mesuré au niveau de la ville, parfois plusieurs années avant le comportement cible (2007, permet de prédire des comportements de masse.

    Full Text Available La paternité japonaise a longtemps été caractérisée par un engagement professionnel exacerbé et une absence marquée au niveau familial. Cependant, le contexte économique et politique récent a induit certains changements dans la manière d’appréhender la paternité. Il est ainsi possible d’identifier trois types de positionnements dans les discours récents relatifs à la paternité au Japon : 1 le père “pourvoyeur”, garantissant les ressources économiques nécessaires aux besoins des enfants, 2 le père “socialisateur”, encadrant ses enfants dans l’apprentissage des normes sociales, 3 le père “soigneur”, aidant ses enfants pour ce qu’ils ne peuvent faire. Il n’est pas facile pour les pères de trouver un équilibre par rapport aux responsabilités que ces trois approches supposent. Les codes professionnels valorisant “l’homme dominant” et les carences du système d’encadrement des enfants obligent de nombreux pères à s’investir énormément dans leur vie professionnelle tandis que de nombreuses mères restent à la maison. Les réactions des pères face à cette situation sont variées. Certains valorisent une division genrée des responsabilités parentales et se consacrent pleinement à leur travail. D’autres articulent travail et famille tandis que l’épouse reste à la maison. D’autres, enfin, optent pour une articulation travail/famille impliquant les deux membres du couple, redéfinissant ainsi la signification de la masculinité.Japanese fatherhood has been characterized as preoccupation with work and alienation from family. However, Japan’s recent political and economic conditions have brought about changes and diversification in fatherhood. We can recognize three types of father’s responsibilities in recent discourses on fatherhood in Japan : 1 “provider,” supplying necessary economic resources for the growth of children, 2 “socializer,” supporting children to learn social norms and good manners, 3 “carer,” helping children by doing what children cannot do. It is difficult for fathers to keep a balance between the responsibility as a provider and as a socializer/carer. Male-dominant employment practices and insufficient child-support systems force many fathers to work very long and many mothers to stay home. Fathers’ reactions to the conflict are various. Some affirm gender division of parental responsibilities and justify their insufficient involvement in childcare. Some take a responsibility as a sole provider and make an effort to get involved in childcare as much as possible. Some try to juggle work and childcare and build egalitarian relationship with his wife, rethinking the meaning of masculinity.

Anthropologists and ethnographers spent a minimum of 5.5 hours with each consented patient and filmed their behaviors in everyday situations. Visual data and notes were analyzed to identify HRQoL-related themes.Results: The study included 50 adult patients. Patients described their appearance with disgust and self-loathing. Frustration was expressed due to a perceived lack of control of their lives. Prior to initiation of biologic treatment, daily rituals absorbed a good part of their day, including applying creams, checking one's appearance, and covering the body. Due to a lack of cultural discourse and patient's difficulty in articulating the impact of psoriasis, partners and family did not know how to react nor did they realize the full extent of the problem, and many patients experienced perceived social discrimination due to psoriasis, leaving them with feelings of isolation. Patients established on biologic treatment noticed a significant physical improvement and regained confidence, but psychosocial impacts, including social isolation, remained.Conclusion: This ethnographic study vividly depicted the unarticulated and emotional impact of psoriasis on the everyday lives of patients and presents an effective method of assessing HRQoL in chronic diseases.Keywords: psoriasis, health-related quality of life, ethnography, patient reported outcomes, conceptual model

  5. A detailed kinetic modeling study of toluene oxidation in a premixed laminar flame

    An improved chemical kinetic model for the toluene oxidation based on experimental data obtained in a premixed laminar low-pressure flame with vacuum ultraviolet (VUV) photoionization and molecular beam mass spectrometry (MBMS) techniques has been proposed. The present mechanism consists of 273 species up to chrysene and 1740 reactions. The rate constants of reactions of toluene, decomposition, reaction with oxygen, ipso-additions and metatheses with abstraction of phenylic H-atom are updated; new pathways of C{sub 4} + C{sub 2} species giving benzene and fulvene are added. Based on the experimental observations, combustion intermediates such as fulvenallene, naphtol, methylnaphthalene, acenaphthylene, 2-ethynylnaphthalene, phenanthrene, anthracene, 1-methylphenanthrene, pyrene and chrysene are involved in the present mechanism. The final toluene model leads to an overall satisfactory agreement between the experimentally observed and predicted mole fraction profiles for the major products and most combustion intermediates. The toluene depletion is governed by metathese giving benzyl radicals, ipso-addition forming benzene and metatheses leading to C{sub 6}H{sub 4}CH{sub 3} radicals. A sensitivity analysis indicates that the unimolecular decomposition via the cleavage of a C-H bond has a strong inhibiting effect, while decomposition via C-C bond breaking, ipso-addition of H-atom to toluene, decomposition of benzyl radicals and reactions related to C{sub 6}H{sub 4}CH{sub 3} radicals have promoting effect for the consumption of toluene. Moreover, flow rate analysis is performed to illustrate the formation pathways of mono- and polycyclic aromatics.

    In this paper, bond cleavage reactions are discussed in relation to the softening and solubilization of coal. Were used 9,10-dihydroanthracene (DHA) and 9,10-dihydrophenanthrene (DHP) as models of hydrogen donating compounds in coal, and bibenzyl, 1,2-diethane, benzylphenylether, and 1,5-dibenzylnaphthalene were used as models of bridge structure compounds. They were compared mutually, as to reactivity of coal against DHA and DHP. For the homolytic cleavage of bridges, DHA with excellent radical supplement performance provided excellent hydrogen donating performance. While, for the ipso-position cleavage of bridges, it was found that DHP can act as an effective hydrogen donor. For the reaction between coal and hydrogenated aromatic compounds, cleavage of relatively weak bonds, such as ether linkage and dimethylene linkage, occurred at about 380{degree}C, and hydrogen from DHA or DHP was consumed. On the other hand, the results suggested that the cleavage reaction at ipso-position affected by hydrogen donating solvent is also important at temperature range around 420{degree}C. 2 refs., 3 figs., 1 tab.

    Full Text Available Meisenheimer complexes are important intermediates in Nucleophilic Aromatic Substitution Reactions (SNAr. They are formed by the addition of electron rich species to polynitro aromatic compounds or aromatic compounds with strong electron withdrawing groups. It is possible to distinguish two types of Meisenheimer or σ-complexes, the σHcomplex or σX-complex (also named ipso, depending on the aromatic ring position attacked by the nucleophile (a non-substituted or substituted one, respectively. Special examples of σX- or ipso-complexes are formed through intermediate spiro adducts, via intramolecular SNAr. Some of these spirocyclic Meisenheimer complexes, a type of σXcomplex, are exceptionally stable in solution and/or as solids. They can be isolated and characterized using X-ray, and various spectroscopic techniques such as NMR, UV-Vis, IR, and fluorescence. A few of these stable spirocyclic Meisenheimer complexes are zwitterionic and exhibit interesting photophysical and redox properties. We will review recent advances, synthesis and potential applications of these stable spirocyclic Meisenheimer complexes.

    2016-03-01

    Full Text Available Classical Q-learning takes huge computation to calculate the Q-value for all possible actions in a particular state and takes large space to store its Q-value for all actions, as a result of which its convergence rate is slow. This paper proposed a new methodology to determine the optimize trajectory of the path for multi-robots in clutter environment using hybridization of improving classical Q-learning based on four fundamental principles with improved particle swarm optimization (IPSO by modifying parameters and differentially perturbed velocity (DV algorithm for improving the convergence. The algorithms are used to minimize path length and arrival time of all the robots to their respective destination in the environment and reducing the turning angle of each robot to reduce the energy consumption of each robot. In this proposed scheme, the improve classical Q-learning stores the Q-value of the best action of the state and thus save the storage space, which is used to decide the Pbest and gbest of the improved PSO in each iteration, and the velocity of the IPSO is adjusted by the vector differential operator inherited from differential evolution (DE. The validation of the algorithm is studied in simulated and Khepera-II robot.

  18. Immune particle swarm optimization of linear frequency modulation in acoustic communication

    Institute of Scientific and Technical Information of China (English)

    Haipeng Ren; Yang Zhao

    2015-01-01

    With the exploration of the ocean, underwater acoustic communication has attracted more and more attention in recent years. The underwater acoustic channel is considered to be one of the most complicated channels because it suffers from more serious multipath effect, fewer available bandwidths and quite complex noise. Since the signals experience a serious distortion after being transmitted through the underwater acoustic channel, the underwater acoustic communication experiences a high bit error rate (BER). To solve this problem, carrier waveform inter-displacement (CWID) modulation is proposed. It has been proved that CWID modulation is an effective method to decrease BER. The linear frequency modulation (LFM) carrier-waves are used in CWID modulation. The performance of the communication using CWID modulation is sensitive to the change of the frequency band of LFM carrier-waves. The immune particle swarm optimization (IPSO) is introduced to search for the optimal frequency band of the LFM carrier-waves, due to its excel ent performance in solving complicated optimization problems. The multi-objective and multi-peak optimization nature of the IPSO gives a suitable description of the relationship between the upper band and the lower band of the LFM carrier-waves. Simulations verify the improved perfor-mance and effectiveness of the optimization method.

    Full Text Available Enhancing speech recognition is the primary intention of this work. In this paper a novel speech recognition method based on vector quantization and improved particle swarm optimization (IPSO is suggested. The suggested methodology contains four stages, namely, (i denoising, (ii feature mining (iii, vector quantization, and (iv IPSO based hidden Markov model (HMM technique (IP-HMM. At first, the speech signals are denoised using median filter. Next, characteristics such as peak, pitch spectrum, Mel frequency Cepstral coefficients (MFCC, mean, standard deviation, and minimum and maximum of the signal are extorted from the denoised signal. Following that, to accomplish the training process, the extracted characteristics are given to genetic algorithm based codebook generation in vector quantization. The initial populations are created by selecting random code vectors from the training set for the codebooks for the genetic algorithm process and IP-HMM helps in doing the recognition. At this point the creativeness will be done in terms of one of the genetic operation crossovers. The proposed speech recognition technique offers 97.14% accuracy.

    At the first Banff Summit for Urban Animal Strategies (BSUAS) in 2006, delegates clearly indicated that a lack of reliable Canadian statistics hampers municipal leaders and legislators in their efforts to develop urban animal strategies that create and sustain a healthy community for pets and people. To gain a better understanding of the situation, BSUAS municipal delegates and other industry stakeholders partnered with Ipsos Reid, one of the world's leading polling firms, to conduct a national survey on the "Business of Urban Animals." The results of the survey, summarized in this article, were presented at the BSUAS meeting in October 2008. In addition, each participating community will receive a comprehensive written analysis, as well as a customized report. The online survey was conducted from September 22 to October 1, 2008. There were 7208 participants, including 3973 pet and 3235 non-pet owners from the Ipsos-Reid's proprietary Canadian online panel. The national results were weighted to reflect the true population distribution across Canada and the panel was balanced on all major demographics to mirror Statistics Canada census information. The margin for error for the national results is 1/- 1.15%.

    This paper reviews the status of various practices used throughout the world for managing low-level radioactive wastes. Most of the information in this review was obtained through the DOE-sponsored International Program Support Office (IPSO) activities at Pacific Northwest Laboratory (PNL) at Richland, Washington. The objective of IPSO is to collect, evaluate, and disseminate information on international waste management and nuclear fuel cycle activities. The center's sources of information vary widely and include the proceedings of international symposia, papers presented at technical society meetings, published topical reports, foreign trip reports, and the news media. Periodically, the information is published in topical reports. Much of the information contained in this report was presented at the Fifth Annual Participants' Information Meeting sponsored by DOE's Low-Level Waste Management Program Office at Denver, Colorado, in September of 1983. Subsequent to that presentation, the information has been updated, particularly with information provided by Dr. P. Colombo of Brookhaven National Laboratory who corresponded with low-level waste management specialists in many countries. The practices reviewed in this paper generally represent actual operations. However, major R and D activities, along with future plans, are also discussed. 98 refs., 6 tabls.

    2014-01-01

    Full Text Available This paper presents a control strategy proposed for power maximizing which is a critical mechanism to ensure power track is maximized. Many tracking algorithms have been proposed for this purpose. One of the more commonly used techniques is the incremental conductance method. In this paper, an improved particle swarm optimization- (IPSO- based MPPT technique for photovoltaic system operating under varying environmental conditions is proposed. The approach of linearly decreasing scheme for weighting factor and cognitive and social parameter is modified. The proposed control scheme can overcome deficiency and accelerate convergence of the IPSO-based MPPT algorithm. The approach is not only capable of tracking the maximum power point under uniform insolation state, but also able to find the maximum power point under fast changing nonuniform insolation conditions. The photovoltaic systematic process with control schemes is created using MATLAB Simulink to verify the effectiveness with several simulations being carried out and then compared with the conventional incremental conductance technique. Lastly, the effectiveness of the intended techniques is proven using real data obtained form previous literature. With the change in insolation and temperature portrait, it produces exceptional MPPT maximization. This shows that optimum performance is achieved using the intended method compared to the typical method.

    Quality function deployment (QFD) is a wel-known customer-oriented product design methodology. Rating the final importance of customer requirements (CRs) is real y a very es-sential starting point in the implementation of QFD, since it largely affects the target setting value of design requirements. This pa-per aims to propose a novel method to deal with the relative importance ratings (RIRs) of CRs problem considering customers’ diversified requirements and unknown information on customers’ weights, which is an indispensable process for determining the final importance ratings of CRs. First, a new concept of customer’s assessment structure is proposed according to the basic idea of grey relational analysis (GRA), and then a constrained nonlinear optimization model is constructed to describe the assessment information aggregation factors of CRs considering customers’ personalized and diversified requirements. Furthermore, an im-mune particle swarm optimization (IPSO) algorithm is designed to solve the model, and the weight vector of customers is obtained. Final y, a car door design example is introduced to il ustrate the novel hybrid GRA-IPSO method’s potential application in deter-mining the RIRs of CRs.

  8. Kinetics and mechanism of the reaction of OH with the trimethylbenzenes--experimental evidence for the formation of adduct isomers.

    Science.gov (United States)

    Bohn, Birger; Zetzsch, Cornelius

    2012-10-28

    The reversible gas-phase addition of OH radicals to the trimethylbenzenes was investigated in pulsed experiments utilizing VUV flash-photolysis resonance-fluorescence of H(2)O in the temperature range of 275-340 K. Triexponential OH decays were observed in the presence of the trimethylbenzenes, indicating the participation of more than one adduct species. Analytical solutions for the system of differential equations with two adduct isomers were derived, and the OH decay curves were evaluated based on this reaction model. This led to significant improvements of fit qualities and notable changes in OH rate constants compared to a previous model with a single adduct species. The detailed analysis was confined to 1,3,5-trimethylbenzene where reversible formation of two OH-aromatic ortho- and ipso-adduct isomers is feasible in accordance with the extended reaction model. Only after inclusion of additional isomerization reactions, consistent thermochemical data were obtained from the fitted rate constants. Reaction enthalpies of -83 ± 7 kJ mol(-1) and -35 ± 22 kJ mol(-1) were derived for the formation of one adduct isomer and the isomerization into the other, respectively. Based on literature data, the more and less stable adducts were assigned to ipso- and ortho-adduct isomers, respectively. The potential isomerization precluded the determination of primary yields of adduct isomers but formation of the ipso-adduct in any case is a minor process. For the rate constants of the OH + 1,3,5-trimethylbenzene reaction an Arrhenius expression k(OH) = 1.32 × 10(-11) cm(3) s(-1) exp(450 ± 50 K/T) was obtained. Based on the same approach, the rate constants of the OH reactions with 1,2,3-trimethylbenzene and 1,2,4-trimethylbenzene were derived as k(OH) = 3.61 × 10(-12) cm(3) s(-1) exp(620 ± 80 K/T) and k(OH) = 2.73 × 10(-12) cm(3) s(-1) exp(730 ± 70 K/T), respectively.

    2013-01-01

    Based on the life cycle cost (LCC) approach, this paper presents an integral mathematical model and particle swarm optimization (PSO) algorithm for the heating system planning (HSP) problem. The proposed mathematical model minimizes the cost of heating system as the objective for a given life cycle time. For the particularity of HSP problem, the general particle swarm optimization algorithm was improved. An actual case study was calculated to check its feasibility in practical use. The results show that the improved particle swarm optimization (IPSO) algorithm can more preferably solve the HSP problem than PSO algorithm. Moreover, the results also present the potential to provide useful information when making decisions in the practical planning process. Therefore, it is believed that if this approach is applied correctly and in combination with other elements, it can become a powerful and effective optimization tool for HSP problem.

    2015-03-01

    Due to its inherent hysteretic characteristics, the main challenge for the application of a magnetorheological elastomer- (MRE) based isolator is the exploitation of the accurate model, which could fully describe its unique behaviour. This paper proposes a nonparametric model for a MRE-based isolator based on support vector regression (SVR). The trained identification model is to forecast the shear force of the MRE-based isolator online; thus, the dynamic response from the MRE-based isolator can be well captured. In order to improve the forecast capacity of the model, a type of improved particle swarm optimization (IPSO) is employed to optimize the parameters in SVR. Eventually, the trained model is applied to the MRE-based isolator modelling with testing data. The results indicate that the proposed hybrid model has a better generalization capacity and better recognition accuracy than other conventional models, and it is an effective and suitable approach for forecasting the behaviours of a MRE-based isolator.

    The mechanism of particle swarm optimization algorithm is studied, and one can draw the conclusion that the best particle found by the swarm falling into local minima is one of the main reasons for premature convergence. Therefore, an improved particle swarm optimization algorithm is proposed. This algorithm selects the best particle with roulette wheel selection method, so premature converging to local optima is avoided. At last, the improved particle swarm optimization algorithm is applied to optimization of time-sharing power supply for zinc electrolytic process. Simulation and practical results show that the global search ability of IPSO is improved greatly and optimization of time-sharing power supply for zinc electrolytic process can bring about outstanding economic benefit for plant.

    This section presents some of the results of four studies on international public opinion about nuclear energy, the first one made several years before the Fukushima accident, conducted in 2005 by the IAEA through the company Globe Scan Inc. The second study was conducted by the same company in 2011 a few months after the Fukushima accident, including also corresponding results to two studies conducted by the British firm Ipsos Mori (of years 2011 and 2012 respectively). Finally three studies conducted by the Instituto Nacional de Investigaciones Nucleares (ININ) in 2006, 2008 and 2013 are presented. From the results of these studies was determined that the Fukushima accident itself had a negative effect on public opinion in Mexico, as throughout the world, but this trend is reversing. Also it found that public opinion in Mexico on using reactors to generate electricity is favorable, although not still has much support from the government for the construction of new nuclear power plants.

    Maurizio Fagnoni

    2013-04-01

    Full Text Available Steady-state irradiation in neat acetonitrile of some aromatic nitriles, imides and esters (10−5–10−3 M solution in the presence of tertiary amines allowed the accumulation of the corresponding radical anions, up to quantitative yield for polysubstituted benzenes and partially with naphthalene and anthracene derivatives. The condition for such an accumulation was that the donor radical cation underwent further evolution that precluded back electron transfer and any chemical reaction with the radical anion. In fact, no accumulation occurred with 1,4-diazabicyclo[2.2.2]octane (DABCO, for which this condition is not possible. The radical anions were produced from benzene polyesters too, but decomposition began early. Ipso substitution was one of the paths with secondary amines and the only reaction with tetrabutylstannane. The results fully support the previously proposed mechanism for electron transfer (ET mediated photochemical alkylation of aromatic acceptors via radical ions and radical intermediates.

  16. Towards a Common Platform to Support Business Processes, Services and Semantics

    Science.gov (United States)

    Piprani, Baba

    The search for the Holy Grail in achieving interoperability of business processes, services and semantics continues with every new type or search for the Silver Bullet. Most approaches towards interoperability either are focusing narrowly on the simplistic notion using technology supporting a cowboy-style development without much regard to metadata or semantics. At the same time, the distortions on semantics created by many of current modeling paradigms and approaches - including the disharmony created by multiplicity of parallel approaches to standardization - are not helping us resolve the real issues facing knowledge and semantics management. This paper will address some of the issues facing us, like: What have we achieved? Where did we go wrong? What are we doing right? - providing an ipso-facto encapsulated candid snapshot on an approach to harmonizing our approach to interoperability, and propose a common platform to support Business Processes, Services and Semantics.

    Survey data on 1217 adults living in Alberta, Canada were collected by Ipsos Reid Public Affairs and made available to us for analysis. The survey questioned participants on issues related to science including their perceived knowledge of science, attitudes toward science, and trust in science and technology. We developed a structural equation model to account for the causal relations implied by the correlations among the variables in the data set. Results show that trust in generalized science and technology is a large determiner of trust in specific technologies, but that trust in specific technologies is not a determinant of overall trust in science and technology. We also found that attitudes towards science have an effect on trust in generalized science and technology whereas perceived knowledge does not. Education and gender contribute to attitudes supporting an increased personal attachment to science, which was the strongest predictor of trust in our model.

    2014-02-01

    Full Text Available A mathematical model of electroslag remelting (ESR process is established based on its technical features and dynamic characteristics. A new multivariable self-tuning proportional-integral-derivative (PID controller tuned optimally by an improved particle swarm optimization (IPSO algorithm is proposed to control the two-input/two-output (TITO ESR process. An adaptive chaotic migration mutation operator is used to tackle the particles trapped in the clustering field in order to enhance the diversity of the particles in the population, prevent premature convergence and improve the search efficiency of PSO algorithm. The simulation results show the feasibility and effectiveness of the proposed control method. The new method can overcome dynamic working conditions and coupling features of the system in a wide range, and it has strong robustness and adaptability.

    An efficient, metal and base-free, chemoselective synthesis of aryl-, heteroaryl-, and alkyl primary amines from the corresponding boronic acids has been achieved at ambient temperature mediated by [bis(trifluoroacetoxy)iodo]benzene (PIFA) and N-bromosuccinimide (NBS) using cyanamidyl/arylcyanamidyl radicals as the aminating species. The primary amine compounds were initially obtained as their corresponding ammonium trifluoroacetate salts which, on treatment with aq NaOH, provide the free amines. Finally, the primary amines were isolated through column chromatography over silica-gel using hexane-EtOAc solvent system as the eluent. The reactions are sufficiently fast, completing within 1 h. Quantum chemical calculations in combination with experimental observations validate that the ipso amination of substituted boronic acids involves the formation of cyanamidyl/arylcyanamidyl radical, followed by regiospecific interaction of its nitrile-N center with boron atom of the boronic acids, leading to chemoselective primary amination.

    Full Text Available A new method called mutable smart bee (MSB algorithm proposed for cooperative optimizing of the maximum power output (MPO and minimum entropy generation (MEG of an Atkinson cycle as a multiobjective, multi-modal mechanical problem. This method utilizes mutable smart bee instead of classical bees. The results have been checked with some of the most common optimizing algorithms like Karaboga’s original artificial bee colony, bees algorithm (BA, improved particle swarm optimization (IPSO, Lukasik firefly algorithm (LFFA, and self-adaptive penalty function genetic algorithm (SAPF-GA. According to obtained results, it can be concluded that Mutable Smart Bee (MSB is capable to maintain its historical memory for the location and quality of food sources and also a little chance of mutation is considered for this bee. These features were found as strong elements for mining data in constraint areas and the results will prove this claim.

    As the U. S. Department of Energy (DOE) and DOE contractors have increased the magnitude and scope of their cooperative activities with other nations in the nuclear fuel cycle and waste management field, a need has developed for ready sources of information concerning foreign waste management programs, DOE technology exchange policies, bilateral fuel cycle and waste management agreements and plans and activities to implement those agreements. The INFX (International InLormation E~change) Guide is one of a series of documents that have been prepared to provide that information. The INFX Guide has been compiled under the charter of PNL's International Support Office (IPSO) to maintain for DOE a center to collect, organize, evaluate and disseminate information on foreign and international radioactive waste management programs. Because the information in this document is constantly subject to change, the document is assembled in loose-leaf form to accommodate frequent updates.

    The reaction between monomeric bis(1,2,4-tri-t-butylcyclopentadienyl)cerium hydride, Cp'2CeH, and several hydrofluorobenzene derivatives is described. The aryl derivatives that are the primary products, Cp'2Ce(C6H5-xFx) where x = 1,2,3,4, are thermally stable enough to be isolated in only two cases, since all of them decompose at different rates to Cp'2CeF and a fluorobenzyne; the latter is trapped by either solvent when C6D6 is used or by a Cp'H ring when C6D12 is the solvent. The trapped products are identified by GCMS analysis after hydrolysis. The aryl derivatives are generated cleanly by reaction of the metallacycle, Cp'((Me3C)2C5H2C(Me2)CH2)Ce, with a hydrofluorobenzene and the resulting arylcerium products, in each case, are identified by their 1H and 19F NMR spectra at 20oC. The stereochemical principle that evolves from these studies is that the thermodynamic isomer is the one in which the CeC bond is flanked by two ortho-CF bonds. This orientation is suggested to arise from the negative charge that is localized on the ipso-carbon atom due to Co(delta+)-Fo(delta-) polarization. The preferred regioisomer is determined by thermodynamic rather than kinetic effects; this is illustrated by the quantitative, irreversible solid-state conversion at 25oC over two months of Cp'2Ce(2,3,4,5-C6HF4) to Cp'2Ce(2,3,4,6-C6HF4), an isomerization that involves a CeC(ipso) for C(ortho)F site exchange.

The stereochemical principle that evolves from these studies is that the thermodynamic isomer is the one in which the CeC bond is flanked by two ortho-CF bonds. This orientation is suggested to arise from the negative charge that is localized on the ipso-carbon atom due to Co(delta+)-Fo(delta-) polarization. The preferred regioisomer is determined by thermodynamic rather than kinetic effects; this is illustrated by the quantitative, irreversible solid-state conversion at 25oC over two months of Cp'2Ce(2,3,4,5-C6HF4) to Cp'2Ce(2,3,4,6-C6HF4), an isomerization that involves a CeC(ipso) for C(ortho)F site exchange.

    Full Text Available The crystal and molecular structures of two diphenyltin bis(dithiocarbamates, [Sn(C6H52(C5H10NOS22], (I, and [Sn(C6H52(C7H14NO2S22], (II, are described. In (I, in which the metal atom lies on a twofold rotation axis, the dithiocarbamate ligand coordinates with approximately equal Sn—S bond lengths and the ipso-C atoms of the Sn-bound phenyl groups occupy cis-positions in the resulting octahedral C2S4 donor set. A quite distinct coordination geometry is noted in (II, arising as a result of quite disparate Sn—S bond lengths. Here, the four S-donors define a trapezoidal plane with the ipso-C atoms lying over the weaker of the Sn—S bonds so that the C2S4 donor set defines a skewed trapezoidal bipyramid. The packing of (I features supramolecular layers in the ab plane sustained by methylene-C—H...π(Sn–aryl interactions; these stack along the c-axis direction with no specific interactions between them. In (II, supramolecular chains along the b-axis direction are formed by methylene-C—O(ether interactions; these pack with no directional interactions between them. A Hirshfeld surface analysis was conducted on both (I and (II and revealed the dominance of H...H interactions contributing to the respective surfaces, i.e. >60% in each case, and other features consistent with the description of the molecular packing above.

    The reaction mechanism for o-xylene with OH radical and O2 was studied by density functional theory (DFT) method. The geometries of the reactants, intermediates, transition states, and products were optimized at B3LYP/6-31G(d,p) level. The corresponding vibration frequencies were calculated at the same level. The single-point calculations for all the stationary points were carried out at the B3LYP/6-311++G(2df,2pd) level using the B3LYP/6-31G(d,p) optimized geometries. Reaction energies for the formation of the aromatic intermediate radicals have been obtained to determine their relative stability and reversibility, and their activation barriers have been analyzed to assess the energetically favorable pathways to propagate the o-xylene oxidation. The results of the theoretical study indicate that OH addition to o-xylene forms ipso, meta, and para isomers of o-xylene-OH adducts, and the ipso o-xylene adduct is the most stable among these isomers. Oxygen is expected to add to the o-xylene-OH adducts forming o-xylene peroxy radicals. And subsequent ring closure of the peroxyl radicals to form bicyclic radicals. With relatively low barriers, isomerization of the o-xylene bicyclic radicals to more stable epoxide radicals likely occurs, competing with O2 addition to form bicyclic peroxy radicals. The study provides thermochemical data for assessment of the photochemical production potential of ozone and formation of toxic products and secondary organic aerosol from o-xylene photooxidation.0

  10. Restrictive concept of surrogacy in the draft text of the Civil Code of Serbia

    Bordaš Bernadet I.

    2015-01-01

    Full Text Available The working draft of the Civil Code of Serbia, which was published in June 2015, includes model-provisions on surrogate motherhood, which is, at present, expressly prohibited by law. The paper gives a survey of the proposed provisions and examines particularly those that define which persons can conclude a contract on surrogacy. By limiting this right to persons holding the nationality of Serbia, or to these nationals and persons residing in the territory of Serbia for at least three (five years the legislator wish to avoid reproductive tourism. Surrogate mothering with cross-border effects gives rise to complicated legal problems as regards the definition and recognition of legal parentage of the intended parents both in the countries in which the surrogate mother gives birth to the child, as well as in countries in which the intended parents wish to live with their child. The restrictive concept which retains surrogate mothering within the borders of the domestic state and between domestic nationals disables outgoing cases of surrogate motherhood, but it is not quite true for persons who are not citizens of Serbia, but living on its territory. For these reasons the paper critically examines these limitations in the proposals, and indicates that the incoming cases of surrogate motherhood cannot be prevented due to the free movement of people. The paper also provides analysis of the legal issues of the incoming cases of surrogate motherhood, and suggests solution for them if in the future Civil Code the proposed ipso jure legal parenthood of intended parents will be adopted. With ipso jure legal parenthood of a child who is born to a surrogate mother abroad there is no need to restrict surrogacy cases to nationals of Serbia or to foreigners domiciled in Serbia for three (five years minimum.

    ABSTRACT:Ground grid has great significance for substations. IEEE Std80-2000 points out that the characteristics of horizontal multilayered earth parameters have a great influence on the grounding performance of ground grids. Apparent resistivity is the direct electrical index, and its mathematical model based on Wenner method is an important means to study earth parameters; the corresponding formula in a generalized integral form can be established utilizing Poisson’s equation and the boundary conditions of point current source in multi-layered soil. With the combination of Prony expansion and Lipschitz integration, the equation for fast computation of apparent resistivity is deduced with the summation of limited polynomial terms. Afterwards, improved particle swarm optimization(IPSO) was adopted to solve the horizontal multi-layered earth model using the measured apparent resistivity while the fitness function is chosen as the RMSE between the measured and computed apparent resistivity. In the end of optimization, the particles corresponding to the minimized fitness function were output as the optimal earth parameters. Compared with those published algorithms, IPSO was verified by two-and three-layered earth model, which demonstrate that it is more effective and feasible to obtain horizontal multi-layered earth parameters. The equation of measured apparent resistivity is simplified under the assumption ofd>10t (d is electrode spacing andt is electrode buried depth); therefore, the measured apparent resistivity with respect tod10t(d为电极间距,t为电极入地深度)假设下进行简化得出的,所以提出剔除d<1m时无效的视在电阻率测量值的方法来提高水平多层土壤参数估计的精度,该方法也能够对采用Wenner法的视在电阻率现场测量提出指导意见。

  12. π-face donation from the aromatic N-substituent of N-heterocyclic carbene ligands to metal and its role in catalysis

    2012-05-16

    In this work, we calculate the redox potential in a series of Ir and Ru complexes bearing a N-heterocyclic carbene (NHC) ligand presenting different Y groups in the para position of the aromatic N-substituent. The calculated redox potentials excellently correlate with the experimental ΔE 1/2 potentials, offering a handle to rationalize the experimental findings. Analysis of the HOMO of the complexes before oxidation suggests that electron-donating Y groups destabilize the metal centered HOMO. Energy decomposition of the metal-NHC interaction indicates that electron-donating Y groups reinforce this interaction in the oxidized complexes. Analysis of the electron density in the reduced and oxidized states of representative complexes indicates a clear donation from the C ipso of the N-substituents to an empty d orbital on the metal. In case of the Ru complexes, this mechanism involves the Ru-alkylidene moiety. All of these results suggest that electron-donating Y groups render the aromatic N-substituent able to donate more density to electron-deficient metals through the C ipso atom. This conclusion suggests that electron-donating Y groups could stabilize higher oxidation states during catalysis. To test this hypothesis, we investigated the effect of differently donating Y groups in model reactions of Ru-catalyzed olefin metathesis and Pd-catalyzed C-C cross-coupling. Consistent with the experimental results, calculations indicate an easier reaction pathway if the N-substituent of the NHC ligand presents an electron-donating Y group. © 2012 American Chemical Society.

    The present study investigated and compared the estrogenic and androgenic activities of the three different classes of environmental pollutants and their metabolites using the XenoScreen XL YES/YAS assay, which has advantages compared with the original YES/YAS protocol. Contrary to the parent brominated flame retardants TBB and TBPH, which demonstrated no or very weak (anti)estrogenic or (anti)androgenic activities, their metabolites, TBBA and TBMEPH, exhibited anti-estrogenic (IC50 for TBBA=31.75 μM and IC50 for TBMEPH=0.265 μM) and anti-androgenic (IC50 for TBBA=73.95 μM and IC50 for TBMEPH=2.92 μM) activities. These results reveal that metabolism can enhance the anti-estrogenic and anti-androgenic effects of these two novel brominated flame retardants. Based on the activities of BPAF, BPF, BPA and MBP, we can conclude that the XenoScreen XL YES/YAS assay gives comparable results to the (anti)estrogenic or (anti)androgenic assays that are reported in the literature. For BPA, it was confirmed previously that the metabolite formed after an ipso-reaction (hydroxycumyl alcohol) exhibited higher estrogenic activity compared with the parent BPA, but this was not confirmed for BPAF and BPF ipso-metabolites, which were not active in the XenoScreen YES/YAS assay. Among the substituted BPA analogues, bis-GMA exhibited weak anti-estrogenic activity, BADGE demonstrated weak anti-estrogenic and anti-androgenic activities (IC50=13.73 μM), and the hydrolysed product BADGE·2H2O demonstrated no (anti)estrogenic or (anti)androgenic activities.

    Full Text Available The electrochemical behavior of a biologically important heterocyclic compound quinoxaline (QUI was investigated by cyclic voltammetry (CV in solutions of differing pH, using a glassy carbon electrode (GCE. The reduction of QUI occurs as a quasi-reversible reaction in acid medium, reaching reversibility in alkaline solutions. The kinetic parameters of the electrode process such as αnα, diffusion coefficient (D and heterogeneous rate constant (ks, were evaluated and discussed. Redox mechanism of QUI was proposed on the basis of experimental results. Reduction process involves a transfer of two electrons and two protons at the pyrazine ring of QUI forming a dihydro-derivative. In acid solutions, the product of QUI reduction undergoes irreversible oxidation in a one-electron process. The electrode processes was found to be diffusion controlled.

    This document presents the analysis made by the French commission of electricity regulation (CRE) about a disagreement between Semmaris company (Rungis, France) and Electricite de France (EdF) concerning the request by Semmaris for the subscription of a single contract of access to the grid for its 18 supply points instead of 9 contracts as proposed by EdF after acceptation of a partial regrouping of some supply points under the same contracts. After examination of the hearings, the CRE requested EdF to establish non-discriminatory objective criteria for the regrouping of different delivery points in a same contract before making a new examination of the disagreement between Semmaris and EdF.

    This dossier presents a status of todays situation of the use of bio-energies in France and of its perspectives of development at the year 2006 vista. Seven aspects of bio-energies are considered: wood fuel, district and industrial heating, biomass production and gasification processes, biogas (methane) production from municipal waste tips, bio-fuels and bio-additives (bio-ethanol, ETBE, colza derived oils, vegetal oil methyl esters), bio-molecules production and valorization as substitutes to petroleum products (lubricants, wetting agents, solvents, polymers, coatings), development of wood materials (environmental advantages: CO{sub 2} immobilization, lower energy needs during fabrication, possible energy valorization at end life).

    Gabriel García Márquez dans son roman Cent ans de solitude présente toute une lignée de personnages qui déambulent au fil de l'histoire pouvant laisser croire dans une premier temps en une apparente chaîne de solidarité qui se délite sous le poids de la mémoire et des événements historiques et ne laissant aucune transcendance qui pourrait apporter une consolation à la solitude absolue de Macondo.

Une revue critique de ses origines, de ses affordances, des fondements des reproches qui lui sont faits et de son usage effectif permet de mettre en lumière combien PowerPoint est une « machine rhétorique » qui modifie les genres communicationnels en y exacerbant l’usage de l’image.

    Dès que l’on traite de questions qui courent sur plusieurs siècles ou millénaires, les dualismes simplificateurs et les raccourcis nous amènent à des anachronismes ou à des transpositions qui n’ont pas lieu d’être. Lorsque les termes sont mal posés, on risque dans certains travaux la réduction de théories à des figures mythiques qui sont extrêmement problématiques dans un cadre scientifique.

    La pobreza es un concepto complejo y multidimensional que puede interpretarse de diferentes formas, ya sea mediante una explicación monetaria o filosófica. Para medir la pobreza se usa lo que llamamos una “línea de pobreza”. Esta línea delimita quién es pobre y quién no. Esta necesidad de cuantificar la pobreza no sólo responde a una búsqueda del conocimiento, sino también a la voluntad de determinar quién tiene derecho a beneficiarse de las ayudas del Estado y c...

Il lui faut donc patienter, s’adapter dans la contrainte au "rhythm" défini par l’administration, tantôt lent, tantôt rapide. Et trouver aussi son propre rythme en posant des actes. Il lui faut faire avec le blues, qui survient souvent par la prise de conscience du décalage entre l’espoir d’une vie meilleure qui avait déclenché le ...
