The crew-scheduling module in the GIST system

The public transportation is gaining importance every year basically duethe population growth, environmental policies and, route and streetcongestion. Too able an efficient management of all the resources relatedto public transportation, several techniques from different areas are beingapplied and several projects in Transportation Planning Systems, indifferent countries, are being developed. In this work, we present theGIST Planning Transportation Systems, a Portuguese project involving twouniversities and six public transportation companies. We describe indetail one of the most relevant modules of this project, the crew-scheduling module. The crew-scheduling module is based on the application of meta-heuristics, in particular GRASP, tabu search and geneticalgorithm to solve the bus-driver-scheduling problem. The metaheuristicshave been successfully incorporated in the GIST Planning TransportationSystems and are actually used by several companies.

L'examen clinique du sein : vidéos d'enseignement des compétences cliniques en gynécologie destinés à un module en ligne

Cette thèse présente un travail audiovisuel « L'examen clinique du sein ». Avec l'unité « L'examen génital » elle forme le module « Gynécologie » du projet Virtual Skills Lab (VSL). Le but du projet VSL est d'établir un portail d'enseignement en ligne pour l'enseignement des compétences cliniques (ce terme étant utilisé ici comme équivalent de l'anglais « clinical skills »). Les compétences traitées sont celles exigées par le Catalogue suisse des objectifs d'apprentissage. L'unité « L'examen clinique du sein » est constituée d'une multitude de courtes séquences vidéo qui peuvent être regardées à la suite ou de manière individuelle. Elle est divisée en étapes logiques telles que l'inspection ou la palpation. Chacune de ces étapes appelées « skill » est présentée de deux façons : comme vue d'ensemble et par une approche pas à pas. La séquence « vue d'ensemble » présente le skill en temps réel et représente donc une visualisation du but à atteindre par l'apprenant. Le skill est décomposé en petites étapes (step), les procédures sont montrées au ralenti, munies d'une explication par une voix off. Le format de ces séquences est présenté en double largeur, la partie de gauche montre l'action, la partie de droite est utilisée pour des tableaux ou des graphiques explicatifs. Les différents gestes des compétences cliniques sont rarement standardisés. Pour VSL, un processus de validation sur la base d'un consensus suisse a été mis en place. Ceci ne veut néanmoins pas dire que les modules VSL validés ont été intégrés dans le curriculum de toutes les universités suisses. Vu la complexité des curriculums et la multitude de facteurs entrant enjeu, notamment sur l'intégration des moyens d'enseignement audiovisuels, leur implémentation est une phase critique de tout projet de ce genre. En Suisse, le multilinguisme y ajoute un degré de complexité. A Lausanne, « L'examen clinique du sein » a été introduit aussi bien dans la formation pré- que postgraduée.

Analyse des besoins du système de prise en charge des addictions en Suisse: Module 1 : revue de littérature

Le but de cette étude est d'explorer et de définir, par une analyse des besoins, si l'offre actuelle en services dans le domaine des addictions est encore adaptée à la situation épidémiologique actuelle des addictions, à l'évolution des types de comportements liés à la dépendance et aux besoins des clients. Il s'agit en particulier de répondre aux questions suivantes: Existe-t-il actuellement des besoins en traitement pour lesquels il n'existe aucune offre appropriée ? Quels groupes ne sont pas ou sont insuffisamment atteints par l'offre existante? A quels genres de problèmes liés à la dépendance et à quels nouveaux besoins des clients les structures oeuvrant dans le domaine de la dépendance sont-elles confrontées? Quels sont les besoins d'adaptation du système de prise en charge nécessaires concernant soit les groupes-cibles de services, soit les types d'offres - en particulier le besoin en nouveaux concepts/modèles de prise en charge pour répondre à l'évolution des besoins? Comment ces structures font-elles face à l'accroissement de l'usage de multiples substances (multi-consommation)?

Effects of communication training on real practice performance: a role-play module versus a standardized patient module.

This study investigated the effectiveness of modules involving standardized patients and role-plays on training communication skills. The first module involved standardized patients and an Objective Structured Clinical Examination (OSCE); the second module consisted of peer role-plays and a written examination. A randomized posttest-only control group design with first-year nursing students was used. The intervention group received one-to-one communication training with direct oral feedback from the standardized patient. The control group had training with peer role-playing and mutual feedback. The posttest involved students' rating their self-efficacy, and real patients and clinical supervisors evaluated their communication skills. No significant differences were found between self-efficacy and patient ratings. However, the clinical supervisors rated the intervention group's communication skills to be significantly (p < 0.0001) superior. Assessments by clinical supervisors indicate that communication training modules including standardized patients and an OSCE are superior to communication training modules with peer role-playing.

Validation of the 34-item Supportive Care Needs Survey and 8-item Breast module French versions (SCNS-SF34-Fr and SCNS-BR8-Fr) in breast cancer patients.

This study aimed to assess the psychometric robustness of the French version of the Supportive Care Needs Survey and breast cancer (BC) module (SCNS-SF34-Fr and SCNS-BR8-Fr). Breast cancer patients were recruited in two hospitals (in Paris, France and Lausanne, Switzerland) either in ambulatory chemotherapy or radiotherapy, or surgery services. They were invited to complete the SCNS-SF34-Fr and SCNS-BR8-Fr as well as quality of life and patient satisfaction questionnaires. Three hundred and eighty-four (73% response rate) BC patients returned completed questionnaires. A five-factor model was confirmed for the SCNS-SF34-Fr with adequate goodness-of-fit indexes, although some items evidenced content redundancy, and a one-factor was identified for the SCNS-BR8-Fr. Internal consistency and test-retest estimates were satisfactory for most scales. The SCNS-SF34-Fr and SCNS-BR8-Fr scales demonstrated conceptual differences with the quality of life and satisfaction with care scales, highlighting the specific relevance of this assessment. Different levels of needs could be differentiated between groups of BC patients in terms of age and level of education (P < 0.001). The SCNS-SF34-Fr and SCNS-BR8-Fr present adequate psychometric properties despite some redundant items. These questionnaires allow for the crucial endeavour to design appropriate care services according to BC patients' characteristics.

Establishment of an in vitro system for studies on the induced resistance of cotton to Xanthomonas campestris pv. malvacearum

An in vitro system for studying the resistance response of cotton (Gossypium hirsutum L.) to Xanthomonas campestris pv. malvacearum was investigated. Cell suspension cultures, established from hypocotyl-derived callus of cotton cultivar 101-102B, were treated with bacterial extracellular polysaccharides (EPS) extracted from the incompatible race 18 of X. campestris pv. malvacearum. EPS at 600 mug/mL caused pronounced darkening of the suspension cultures, as indicative of cell death, 48 hours after incubation. Protein electrophoresis analysis of the time course of EPS-treated cells showed differential accumulation of several protein bands after 12-24 hours. The time course of protein accumulation and cell death was consistent with an elicitor-mediated hypersensitive response.

Sobrevivência de Xanthomonas axonopodis pv. manihotis em manipueira sob condições ambientais

O objetivo deste trabalho foi avaliar a sobrevivência de um isolado de Xanthomonas axonopodis pv. manihotis (Xam), resistente ao sulfato de estreptomicina, em manipueira incubada em condições ambientais, em três épocas (março, julho e outubro de 2000). Foram utilizados um meio de cultura semi-seletivo para o isolamento de X. axonopodis pv. manihotis e a técnica de reação de polimerase em cadeia (PCR) ou de amplificação biológica (BIO-PCR). Foram determinados o pH e a acidez total da manipueira durante o período de incubação estudado. O isolado sobreviveu por um período inferior a 24 horas, nas três épocas do ano. A técnica de PCR ou BIO-PCR não foi eficaz em monitorar a sobrevivência do isolado em manipueira, pois apresentou resultados contraditórios e não confiáveis. Observou-se queda do pH e aumento da acidez total da manipueira incubada nas condições estudadas, que pode explicar o comportamento da sobrevivência de Xam em manipueira.

The activity of the anti-apoptotic fragment generated by the caspase-3/p120 RasGAP stress-sensing module displays strict Akt isoform specificity.

The caspase-3/p120 RasGAP module acts as a stress sensor that promotes pro-survival or pro-death signaling depending on the intensity and the duration of the stressful stimuli. Partial cleavage of p120 RasGAP generates a fragment, called fragment N, which protects stressed cells by activating Akt signaling. Akt family members regulate many cellular processes including proliferation, inhibition of apoptosis and metabolism. These cellular processes are regulated by three distinct Akt isoforms: Akt1, Akt2 and Akt3. However, which of these isoforms are required for fragment N mediated protection have not been defined. In this study, we investigated the individual contribution of each isoform in fragment N-mediated cell protection against Fas ligand induced cell death. To this end, DLD1 and HCT116 isogenic cell lines lacking specific Akt isoforms were used. It was found that fragment N could activate Akt1 and Akt2 but that only the former could mediate the protective activity of the RasGAP-derived fragment. Even overexpression of Akt2 or Akt3 could not rescue the inability of fragment N to protect cells lacking Akt1. These results demonstrate a strict Akt isoform requirement for the anti-apoptotic activity of fragment N.
