Les arènes de la normalisation internationale à l'épreuve de la participation : le projet INTERNORM

Our paper presents a pilot project (INTERNORM) funded by the University of Lausanne to support the involvement of not-for-profit organisations in international standard setting bodies such as the ISO. It analyses preliminary results on how a distinct participatory mechanism can influence the institutional environment of technical diplomacy in which ISO standards are developed. It reflects on the contribution of innovative deliberative mechanisms to democratise the field of international standardisation, largely dominated by expert knowledge and market players. It draws upon international relations literature on new institutional forms in global governance and social studies of science on participatory issues in science-society relations. The paper argues that there are significant limitations to the rise of civil society participation in such global governance mechanisms and examines several types of barriers to the involvement of not-for-profit organisations in ISO standard-setting processes. Notre communication porte sur un projet pilote (INTERNORM) financé par l'Université de Lausanne pour favoriser l'implication des acteurs associatifs dans l'élaboration des normes internationales de type ISO. Elle analyse les effets d'un dispositif participatif sur l'environnement institutionnel très particulier de la diplomatie technique ayant cours à l'ISO. Elle présente les résultats intermédiaires d'une réflexion sur l'apport de dispositifs délibératifs pour démocratiser le champ de la normalisation internationale, largement dominé par le savoir expert et les acteurs économiques. Elle situe cette réflexion au croisement des travaux de relations internationales sur les nouvelles formes institutionnelles de la gouvernance de la mondialisation et des études sociales des sciences et des techniques sur la participation dans les rapports science - société. En identifiant plusieurs registres dans lesquels situer les difficultés d'une plus grande implication des acteurs associatifs dans les procédures d'élaboration de spécifications techniques de type ISO, nous posons l'hypothèse qu'il existe d'importantes limites à l'accroissement de la dimension participative de la gouvernance globale.

Infection prothétique de hanche à Listeria monocytogenes [Prosthetic hip infection due to Listeria monocytogenes: review of the literature and case report].

With the ageing of the population, articular prosthetic replacements are becoming more and more frequent. One of the most feared complications is prosthetic infection, mostly due to bacteria of the cutaneous flora. Listeria monocytogenes is rarely the cause. This paper describes the management of a hip prosthetic infection due to Listeria monocytogenes. The patient was cured with antimicrobial therapy and a two-stage exchange. This case report creates an opportunity to review the literature in the aim of determining the risk factors and the optimal care.

La evaluación como elemento clave de la formación basada en competencias: tres casos en el ámbito de la ingenierías

El Espacio Europeo de Educación Superior implica cambios organizativos y académicos referentes a la formación basada en competencias. El proyecto AlineaME, coordinado por la Unidad de Soporte a la Calidad y la Innovación Docente de la Escuela Superior Politécnica - Universidad Pompeu Fabra, propuso a docentes del área TIC y a pedagogos la reflexión conjunta en aras a diseñar recomendaciones centradas en la alineación entre los tres elementos clave del proyecto: competencias, metodología y evaluación (C*M*E). Este trabajo recoge tres casos de aplicación de recomendaciones, concretamente de Ingeniería Telemática (dos casos - Universidad de Valladolid y Pompeu Fabra) y de Ingeniería Técnica en Informática de Gestión (un caso - Universidad de Sevilla).Las recomendaciones aplicadas hacen referencia a la necesidad de explicitar la alineación C*M*E en los Planes Docentes de Asignaturas y de presentar esta alineación al estudiantado. También a la integración de la evaluación de la asignatura como tarea-proceso de aprendizaje. La metodología seguida para laaplicación de ambas es (salvo pequeñas diferencias) parecida en los tres casos. La primera recomendación consistió en recoger en el Plan Docente la Alineación y en verbalizar dicha alineación en la sesión de presentación de la asignatura. La segunda se incorporó incluyendo actividades formativas en las que se favorecía la evaluación entre iguales. Para evaluar la aplicación de recomendaciones se recogieron evidencias en clave de satisfacción por parte del estudiantado así como valoraciones de los propios docentes. Para ello se diseñaron instrumentos específicos.En cuanto a la presentación de la alineación C*M*E en los Planes Docentes de asignaturas, los resultados indican que los alumnos son más conscientes de qué, cómo y por qué van a trabajar y ser evaluados. Globalmente valoran positivamente su utilidad para la autorregulación. Asimismo, plantear la evaluación como tarea deaprendizaje resultó ser para los estudiantes un interesante elemento de reflexión.

Sensing, uptake and response to c4-dicarboxylic acids in pseudomonas aeruginosa pao1

C4-dicarboxylates are one of the preferred carbon and energy sources for the growth of P. aeruginosa, a ubiquitous and metabolically versatile bacterium. However, despite their importance, C4-dicarboxylates sensing and uptake systems were poorly understood in P. aeruginosa and only little information was available in the literature. In our work, the C4-dicarboxylate transport (Dct) system in P. aeruginosa was found to be composed of a novel two-component system, called DctB/DctD, regulating together with the sigma factor RpoN the expression of two newly identified C4-dicarboxylate transporters: DctA and DctPQM. Inactivation of the dct A, dctB or dctD gene caused a growth defect of the strain in minimal media supplemented with succinate, fumarate or malate, indicating their major role in Dct. However, residual growth of the dctA mutant in these media suggested the presence of redundant C4-dicarboxylate transporter(s). Tn5 insertion mutagenesis of the kdctA mutant, combined with a screening for growth on succinate, led to the identification of a second Dct system, the DctPQM transporter, belonging to the tripartite ATP-independent periplasmic (TRAP) family of carriers. AdctAAdctPQM double mutant showed no growth on malate and fumarate albeit residual growth on succinate suggested that additional transporters for succinate are present. Competition experiments demonstrated that the DctPQM carrier was more efficient than the DctA carrier for the utilization of succinate at μΜ concentrations, whereas DctA was the major transporter at mM concentrations. For the first time, high- and low-affinity uptake systems for succinate (DctA and DctPQM) are reported to function co-ordinately to transport C4- dicarboxylates. Most probably, the presence of redundant uptake systems contributes to the versatility of this bacterium. Next, the regulation of the Dct system was investigated. While performing a parallel study about the carbon catabolite repression (CCR) phenomenon in P. aeruginosa, a link between the CCR cascade (CbrAB/CrcZ/Crc) and the Dct system was observed. Crc is a translational repressor acting when preferred carbon sources (like C4-dicarboxylates) are present. CrcZ is a small RNA acting as a functional antagonist of Crc and induced by the CbrA/CbrB two-component system when non preferred carbon sources (like mannitol) are utilized. Novel targets of the CbrAB/CrcZ/Crc system in P. aeruginosa were identified using transcriptome analysis; among them dctA and dctPQM were detected. CCR is regulating the dct transporter genes expression depending on the succinate concentrations in the medium of growth; this modulation of CCR is possible because, at the same time, succinate concentrations tune CCR. In a medium containing high succinate concentrations, CrcZ levels were low and therefore Crc inhibited the translation of mRNA targets. Whereas in a medium containing low succinate concentrations, the subsequent increase of CrcZ levels sequestered Crc, inhibiting its activity. This model shows for the first time that CCR possesses a feedback-based circuitry, a very important type of regulatory loop that confers the best adaptive response under changing environmental conditions. The expression of the dct transporter genes is also found to be regulated by the RNA chaperone protein Hfq. Hfq has the same post-transcriptional effect than Crc at high concentration of succinate, i.e. inhibiting dctP and dctR and indirectly favouring dctA expression. Moreover, an additional indirect positive regulation of dctP expression by Hfq was found. Finally, a metabolome approach was performed to investigate the internal signals modulating CCR via induction of CbrA activity in P. aeruginosa PAOl and P. putida KT2442. The results of the analysis are currently under study in the laboratory. - Les acides C4-dicarboxyliques font partie des sources de carbone et d'énergie préférés de P. aeruginosa, une bactérie versatile et ubiquitaire. Néanmoins, malgré leur importance, comment la présence des acides C4-dicarboxyliques dans le milieu est sentie par la bactérie et comment ils sont transportés dans la cellule chez P. aeruginosa n'étaient pas connus. De plus, peu d'informations sur ces procédés ont été répertoriées dans la littérature. Grace à notre travail, le système de transport des acides C4-dicarboxyliques (Dct) chez P. aeruginosa a pu être caractérisé. En effet, il est composé d'un nouveau système à deux composants, nommé DctB/DctD, qui régule, en combinaison avec le facteur sigma alternatif RpoN, l'expression des deux nouveaux transporteurs des acides C4-dicarboxyliques: DctA et DctPQM. L'inactivation des gènes dctA, dctB or dctD cause un défaut de croissance des souches mutantes dans un milieu minimum contenant du succinate, fumarate ou malate; confirmation de leur rôle dans le Dct. Cependant, une croissance résiduelle du mutant dctA dans ces milieux suggérerait une redondance des transporteurs d'acides Grdicarboxyliques. Une expérience de mutagenèse dans la souche AdctA, utilisant le transposon Tn5, combiné avec un criblage génétique sur la croissance dans le succinate, nous a permis d'identifier le deuxième transporteur DctPQM. DctPQM appartient à la famille des transporteurs TRAP (tripartite ATP-independent periplasmic). Un double mutant AdctAAdctPQM ne pousse pas dans du malate ou fumarate mais par contre présente une croissance résiduelle dans le succinate suggérant l'existence de transporteurs supplémentaires pour le succinate. En réalisant des expériences de compétitions nous avons démontré que le transporteur DctPQM est plus efficace que le transporteur DctA pour l'utilisation de succinate à une concentration de l'ordre du μΜ. Par contre, DctA est le transporteur le plus important pour une concentration de succinate de l'ordre du raM. Pour la première fois, deux systèmes de transport, un avec une forte- et un avec une faible-affinité (DctA et DctPQM) pour le succinate, sont coordonnés dans leur activité de transport des acides C4- dicarboxyliques, probablement contribuant à la versatilité de la bactérie. Ensuite, nous avons étudié la régulation du system Dct. En effectuant, en parallèle, une étude sur le phénomène de la répression catabolique (RC) chez P. aeruginosa, un lien entre la RC et le système Dct a été observé. La cascade des régulateurs formant la RC est composée de CbrA/CbrB, CrcZ et Crc. Crc est un répresseur traductionnel qui agit quand des sources de carbone préférées (comme les acides C4-dicarboxyliques) sont présentes dans le milieu. CrcZ est un petit ARN non-codant qui agit comme antagoniste de Crc. L'expression de CrcZ est induite par le système à deux composants CbrA/CbrB lorsque une source de carbone non-préférée est utilisée (comme le mannitol). Des nouvelles cibles du système CbrAB/CrcZ/Crc chez P. aeruginosa ont été identifiées grâce à une analyse du transcriptome des souches mutantes des régulateurs de la cascade. Parmi les cibles identifiées, les gènes dctA et dctPQM étaient présents. La RC régule l'expression des transporteurs dct en fonction de la concentration de succinate dans le milieu de croissance. Cette régulation est possible parce que, en même temps, les acides C4- dicarboxyliques régulent la RC. Dans un milieu contenant une grande concentration du succinate, le niveau d'expression de CrcZ est faible, donc Crc peut inhiber l'expression de ces ARN messagers cibles. Par contre, dans un milieu avec une faible concentration de succinate, l'augmentation de l'expression de CrcZ titre Crc et inhibe son activité. Ce modèle de régulation rétroactive est très important pour le phénomène de la RC, parce qu'il permet à la bactérie d'accorder une meilleure réponse à un changement environnemental. L'expression des gènes codant pour les transporteurs dct sont aussi régulés par la protéine chaperonne d'ARN Hfq. Hfq semble avoir le même effet traductionnelle que Crc, lorsqu'il y a une forte concentration de succinate. Nous avons ainsi observé une régulation négative de l'expression du gène dct Ρ et dctR, qui code pour un répresseur de la transcription de dctA. Nous avons aussi observé une régulation positive de la transcription de dctP par Hfq, probablement de façon indirecte. Enfin, une analyse du metabolome a était utilisée pour chercher les signaux internes modulant la RC et, en particulier, l'activité de la protéine senseur CbrA chez P. aeruginosa PAOl et P. putida KT2442. Les résultats de l'analyse sont en cours d'étude dans le laboratoire.

Money, Fame and the Allocation of Talent: Brain Drain, the Matthew Effect and the Institution of Science

The earning structure in science is known to be flat relative to the one in the private sector, which could cause a brain drain toward the private sector. In this paper, we assume that agents value both money and fame and study the role of the institution of science in the allocation of talent between the science sector and the private sector. Following works on the Sociology of Science, we model the institution of science as a mechanism distributing fame (i.e. peer recognition). We show that since the intrinsic performance is less noisy signal of talent in the science sector than in the private sector, a good institution of science can mitigate the brain drain. We also find that providing extra monetary incentives through the market might undermine the incentives provided by the institution and thereby worsen the brain drain. Finally, we study the optimal balance between monetary and non-monetary incentives in science.

Prevalence of nursing diagnosis of fluid volume excess in patients undergoing hemodialysis

Objective: To identify the prevalence of nursing diagnosis of fluid volume excess and their defining characteristics in hemodialysis patients and the association between them. Method: Cross-sectional study conducted in two steps. We interviewed 100 patients between the months of December 2012 and April 2013 in a teaching hospital and one hemodialysis clinic. The inference was performed by diagnostician nurses between July and September 2013. Results: The diagnostic studied was identified in 82% of patients. The characteristics that were statistically associated: bounding pulses, pulmonary congestion, jugular vein distention, edema, change in electrolytes, weight gain, intake greater than output and abnormal breath sounds. Among these, edema and weight gain had the highest chances for the development of this diagnostic. Conclusion: The analyzed diagnostic is prevalent in this population and eight characteristics presented significant association.


Health problems of nursing workers in a public educational institution

A case of suicide by ingestion of caffeine.

Intentional or unintentional caffeine abuse due to excessive intake of beverages or energy drinks containing caffeine is relatively frequent. However, death due to caffeine intoxication is rare and case reports of fatalities from caffeine toxicity are relatively infrequent. In this report, we describe an autopsy case involving a 31 year-old man who intentionally took a large amount of caffeine tablets in the form of a weight loss supplement as part of a suicide plan. Caffeine femoral blood concentration (170 mg/l) was within the toxic and potentially lethal ranges reported in the literature in similar cases. Postmortem biochemistry results suggested depressed glomerular filtration rate and pre-renal failure at the time of death but failed to reveal myoglobinuria, glycosuria, ketonuria or ketonemia. Based on the absence of pathological findings at autopsy and the high blood caffeine level, death was attributed to acute caffeine toxicity. The case emphasizes the usefulness of performing exhaustive toxicology and searching for all potentially relevant information in order to formulate appropriate hypotheses concerning the cause and manner of death.

O texto literário na aula de português L2: uma proposta de didactização: Vida e morte de João Cabafume, de Gabriel Mariano

Na concepção deste trabalho, que tem como tema O texto literário na aula de Português L2 – Uma proposta de didactização: Vida e Morte de João Cabafume, de Gabriel Mariano, procurámos investigar e reflectir sobre a abordagem do texto literário no 3º ciclo do ensino secundário cabo-verdiano, especificamente na aula de Português L2, nas áreas de estudos Científica e Tecnológica e Económica e Social, do 11º ano de escolaridade, seguida da apresentação, a título de exemplo, de uma proposta de didactização do texto acima mencionado, na perspectiva da utilização do texto literário como material em que o uso estético da língua potencia a dimensão plural da significação. Para a consecução dos objectivos propostos, procurámos dar visibilidade, na perspectiva da leitura do texto literário, às orientações do programa, às potenciais práticas pedagógicas no ensino de narrativa literária, incluindo os métodos de ensino, os recursos utilizados pelos professores, a forma como os alunos encaram todo o processo de leitura do texto literário em que está envolvido. No entanto, para a concepção da proposta de didactização, procurámos cruzar propostas metodológicas de modelos de leitura e métodos de ensino do texto narrativo e de línguas defendidos por vários autores do campo da didáctica da literatura e das línguas, cujos princípios assentam em bases que valorizam a interacção entre o texto e o leitor. Partindo de um conto de Gabriel Mariano, escritor cabo-verdiano, Vida e Morte de João Cabafume, tentámos propor um roteiro de leitura adequada do texto narrativo, de forma a conduzir o aluno não só na leitura do contexto narrativo, como também na compreensão da dimensão plural da língua enquanto material estético, procurando desenvolver, fundamentalmente, as suas atitudes, os valores éticos e morais e, num âmbito complementar, as suas competências da escrita e da oralidade. Palavras-chave: Texto Literário, Leitura, Escrita, Oralidade, Português L2.

Aprendizagens em contexto de formação inicial: um estudo com futuros professores de ciências em Cabo Verde

O estudo faz parte de um projecto mais amplo, desenvolvido no âmbito do Grupo ESSA (Estudos Sociológicos em Sala de Aula), centrado na formação inicial de professores de ciências. Neste estudo partiu-se do seguinte problema: Que prática(s) pedagógica(s) é(são) implementada(s) na formação inicial de professores de ciências em Cabo Verde e de que forma essa(s) prática(s) se reflecte(m) na aprendizagem e intervenção pedagógica dos formandos? Teoricamente, o estudo baseia-se, em termos sociológicos, no modelo do discurso pedagógico de Bernstein (Bernstein, 2000). Em termos psicológicos, baseia-se nas ideias de Vygotsky (1978) e, na sua vertente epistemológica, na conceptualização de Ziman (1984) sobre a construção da ciência. Metodologicamente, o estudo enquadra-se numa abordagem de investigação mista. Com base numa dialéctica entre o teórico e o empírico, construíram-se instrumentos para caracterizar o contexto de formação inicial e a prática em sala de aula, e um guião de entrevista para apreciar as aprendizagens dos formandos. A investigação envolveu uma formadora e formandos de uma disciplina da área da Metodologia da Biologia de uma Escola Superior de Educação. Os resultados mostraram que o contexto específico de formação se caracterizou, em particular, pela desvalorização do trabalho experimental e da relação entre ciência e metaciência, por um baixo nível de exigência conceptual, por uma fraca articulação entre os conhecimentos e por um grau muito baixo de explicitação do texto a ser adquirido pelos formandos. Revelaram também que a formação pouco contribuiu para a aprendizagem e intervenção pedagógica dos formandos, isto é, para a aquisição da orientação específica de codificação (regras de reconhecimento e de realização) para características relacionadas com o que e com o como do ensino/aprendizagem das ciências. O estudo pretende contribuir com sugestões sobre a inclusão de características pedagógicas da aprendizagem científica na formação inicial de professores de ciências em Cabo Verde e permite reflectir sobre a importância da utilização de instrumentos metodológicos que possibilitem uma análise comparativa entre contextos e textos presentes na formação de professores.

Relationship of aerobic fitness and motor skills with memory and attention in preschoolers (Ballabeina): A cross-sectional and longitudinal study.

Background: The debate about a possible relationship between aerobic fitness and motor skills with cognitive development in children has recently re-emerged, because of the decrease in children's aerobic fitness and the concomitant pressure of schools to enhance cognitive performance. As the literature in young children is scarce, we examined the cross-sectional and longitudinal relationship of aerobic fitness and motor skills with spatial working memory and attention in preschool children.Methods: Data from 245 ethnically diverse preschool children (mean age: 5.2 (0.6) years, girls: 49.4%) analyzed at baseline and 9 months later. Assessments included aerobic fitness (20 m shuttle run) and motor skills with agility (obstacle course) and dynamic balance (balance beam). Cognitive parameters included spatial working memory (IDS) and attention (KHV-VK). All analyses were adjusted for age, sex, BMI, migration status, parental education, native language and linguistic region. Longitudinal analyses were additionally adjusted for the respective baseline value.Results: In the cross-sectional analysis, aerobic fitness was associated with better attention (r = 0.16, p = 0.03). A shorter time in the agility test was independently associated with a better performance both in working memory (r = -0.17, p = 0.01) and in attention (r = -0.20, p = 0.01). In the longitudinal analyses, baseline aerobic fitness was independently related to improvements in attention (r = 0.16, p = 0.03), while baseline dynamic balance was associated with improvements in working memory (r = 0.15, p = 0.04).Conclusions: In young children, higher baseline aerobic fitness and motor skills were related to a better spatial working memory and/or attention at baseline, and to some extent also to their future improvements over the following 9 months.
