What Are Effective Program Characteristics of Self-Management Interventions in Patients With Heart Failure? : An Individual Patient Data Meta-analysis

Background To identify those characteristics of self-management interventions in patients with heart failure (HF) that are effective in influencing health-related quality of life, mortality, and hospitalizations. Methods and Results Randomized trials on self-management interventions conducted between January 1985 and June 2013 were identified and individual patient data were requested for meta-analysis. Generalized mixed effects models and Cox proportional hazard models including frailty terms were used to assess the relation between characteristics of interventions and health-related outcomes. Twenty randomized trials (5624 patients) were included. Longer intervention duration reduced mortality risk (hazard ratio 0.99, 95% confidence interval [CI] 0.97–0.999 per month increase in duration), risk of HF-related hospitalization (hazard ratio 0.98, 95% CI 0.96–0.99), and HF-related hospitalization at 6 months (risk ratio 0.96, 95% CI 0.92–0.995). Although results were not consistent across outcomes, interventions comprising standardized training of interventionists, peer contact, log keeping, or goal-setting skills appeared less effective than interventions without these characteristics. Conclusion No specific program characteristics were consistently associated with better effects of self-management interventions, but longer duration seemed to improve the effect of self-management interventions on several outcomes. Future research using factorial trial designs and process evaluations is needed to understand the working mechanism of specific program characteristics of self-management interventions in HF patients.

A New Sense of Motion: Framing the Idea of the Archive in the New Information Order

In evolution: that there are a myriad of ways a diversity of folks can archive digital documents (perhaps as print).Documents can only move through containers, and those containers rely on perception to be used.Further, the decision of what constitutes an archive is up to the archon.

Peptide-based low molecular weight gelators for the preparation of self-assembled materials

Low molecular weight gelators (LMWGs) based on pseudo-peptides are here studied for the preparation of supramolecular materials. These compounds can self-assemble through non-covalent interactions such as hydrogen bonds and π-π stacking, forming fibres and gels. A wide variety of materials can be prepared starting from these building blocks, which can be tuned and functionalised depending on the application. In this work, derivatives of the three aromatic amino acids L-Phenylalanine, L-Tyrosine and L-DOPA (3,4-dihydroxiphenylalanine) were synthesised and tested as gelators for water or organic solvents. First, the optimal gelating conditions were studied for each compound, varying concentration, solvent and trigger. Then the materials were characterised in terms of mechanical properties and morphology. Water remediation from dye pollution was the first focus of this work. Organogels were studied as absorbent of dyes from contaminated water. Hydrogels functionalised with TiO2 nanoparticles and graphene platelets were proposed as efficient materials for the photo-degradation of dyes. An efficient method for the incorporation of graphene inside hydrogels using the gelator itself as dispersant was proposed. In these materials a high storage modulus coexists with good self-healing and biocompatibility. The incorporation of a mineral phase inside the gel matrix was then investigated, leading to the preparation of composite organic/inorganic materials. In a first study, the growth of calcium carbonate crystals was achieved inside the hydrogel, which preserved its structure after crystal formation. Then the self-assembled fibres made of LMWGs were used for the first time instead of the polymeric ones as reinforcement inside calcium phosphate cements (CPCs) for bone regeneration. Gel-to-crystal transitions occurring with time in a metastable gel were also examined. The formation of organic crystals in gels can be achieved in multicomponent systems, in which a second gelator constitutes the independent gel network. Finally, some compounds unable to gelate were tested as underwater adhesives.

Nanostructured piezoelectric materials for the design and development of self-sensing composite materials and energy harvesting devices

The work activities reported in this PhD thesis regard the functionalization of composite materials and the realization of energy harvesting devices by using nanostructured piezoelectric materials, which can be integrated in the composite without affecting its mechanical properties. The self-sensing composite materials were fabricated by interleaving between the plies of the laminate the piezoelectric elements. The problem of negatively impacting on the mechanical properties of the hosting structure was addressed by shaping the piezoelectric materials in appropriate ways. In the case of polymeric piezoelectric materials, the electrospinning technique allowed to produce highly-porous nanofibrous membranes which can be immerged in the hosting matrix without inducing delamination risk. The flexibility of the polymers was exploited also for the production of flexible tactile sensors. The sensing performances of the specimens were evaluated also in terms of lifetime with fatigue tests. In the case of ceramic piezo-materials, the production and the interleaving of nanometric piezoelectric powder limitedly affected the impact resistance of the laminate, which showed enhanced sensing properties. In addition to this, a model was proposed to predict the piezoelectric response of the self-sensing composite materials as function of the amount of the piezo-phase within the laminate and to adapt its sensing functionalities also for quasi-static loads. Indeed, one final application of the work was to integrate the piezoelectric nanofibers in the sole of a prosthetic foot in order to detect the walking cycle, which has a period in the order of 1 second. In the end, the energy harvesting capabilities of the piezoelectric materials were investigated, with the aim to design wearable devices able to collect energy from the environment and from the body movements. The research activities focused both on the power transfer capability to an external load and the charging of an energy storage unit, like, e.g., a supercapacitor.

Analytic models of self-gravitating rotating gaseous tori with central black hole

In this thesis project, I present stationary models of rotating fluids with toroidal distributions that can be used to represent the active galactic nuclei (AGN) central obscurers, i.e. molecular tori (Combes et al., 2019), as well as geometrically thick accretion discs, like ADAF discs (Narayan and Yi, 1995) or Polish doughnuts (Abramowicz, 2005). In particular, I study stationary rotating systems with a more general baroclinic distribution (with a vertical gradient of the angular velocity), which are often more realistic and less studied, due to their complexity, than the barotropic ones (with cylindrical rotation), which are easier to construct. In the thesis, I compute analytically the main intrinsic and projected properties of the power-law tori based on the potential-density pairs of Ciotti and Bertin (2005). I study the density distribution and the resulting gravitational potential for different values of α, in the range 2 < α < 5. For the same models, I compute the surface density of the systems when seen face-on and edge-on. I then apply the stationary Euler equations to obtain rotational velocity and temperature distributions of the self-gravitating models in the absence of an external gravitational potential. In the thesis I also consider the power-law tori with the presence of a central black hole in addition to the gas self-gravity, and solving analytically the stationary Euler equations, I compute how the properties of the system are modified by the black hole and how they vary as a function of the black hole mass. Finally, applying the Solberg-Høiland criterion, I show that these baroclinic stationary models are linearly stable in the absence of the black hole. In the presence of the black hole I derive the analytical condition for stability, which depends on α and on the black hole mass. I also study the stability of the tori in the hypothesis that they are weakly magnetized, finding that they are always unstable to this instability.

Relatório de estágio realizado na Escola Secundária José Gomes Ferreira

Para a grande maioria dos professores, tornarem-se melhores profissionais passa pelo alcance máximo de sucesso pelos seus alunos (Guskey, 2002), sendo este o principal foco deste relatório. A interligação entre as quatro áreas de intervenção do estágio pedagógico, permite potencializar cada uma. A reflexão sobre o desenvolvimento pessoal e profissional enquanto professora estagiária tendo em conta um sentimento de auto-eficácia positivo (Jardim & Onofre, 2009) e uma inteligência emocial (Mouton, Hansenne, Delcour & Coles, 2013) foi fundamental para contribuir para uma gestão correta da sala de aula através do modelo ecológico (Hastie e Siedentop, 1999) em conjunto com as 4 dimensões de uma intervenção pedagógico de sucesso (Sidentop, 1983; citado por Onofre, 1995). Tornando-se essencial entender a evolução e as diferenças entre os alunos por ser o centro do processo de ensino-aprendizagem. Assim, o trabalho do professor, começa muito antes do espaço de sala de aula (Fentermacher & Soltis, 1986). A comunidade escolar da Escola Secundária José Gomes Ferreira, compreende que a disciplina tem benefícios educacionais, mas nem sempre a consegue suportar. Assim, é necessário promover experiências positivas no 1º ciclo, de forma a desenvolver atitudes positivas face à Educação Física.

Promoting young people's social and emotional wellbeing in secondary education.

This guidance is for all those who have a responsibility for the social and emotional wellbeing of young people in secondary education. This includes teachers, support staff, governors and professionals with public health as part of their remit working in education (including the independent sector), local authorities, the NHS and the wider public, voluntary and community sectors. It focuses on interventions to support all young people aged 11-19 who attend any education establishment. Social and emotional wellbeing includes being happy, confident and in control, with the ability to solve and cope with problems and have good relationships with other people. The six recommendations cover: strategy, the key principles and conditions, working in partnership with parents, families and young people, the curriculum, and training and professional development. They include: â?¢ Secondary education establishments should have access to the specialist skills, advice and support they require. â?¢ Practitioners should have the knowledge, understanding and skills they need to develop young peopleâ?Ts social and emotional wellbeing. â?¢ Secondary education establishments should provide a safe environment which nurtures and encourages young peopleâ?Ts sense of self-worth, reduces the threat of bullying and violence and promotes positive behaviour. â?¢ Social and emotional skills education should be tailored to the developmental needs of young people.This resource was contributed by The National Documentation Centre on Drug Use.

Am I my brain or my genitals? A nature-culture controversy in the hermaphrodite debate from the mid-1960s to the late 1990s.

The groundbreaking and prophetic rhetoric of neuroscience has recently highlighted the fetal brain as the most promising organ for understanding why transsexuals feel "trapped in the wrong body", and for predicting whether children born with "ambiguous" genitalia will grow up to feel like a man or a woman.This article proposes a recent history of the cerebralization of intersexuality and of transsexuality as atypical neurodevelopmental conditions. It examines the ways in which the organizational theory of brain sex differentiation developed in the late 1950s in behavioral neuroendocrinology has gained increased prominence in and through controversies over best practice issues in the case management of intersex newborns, and the etiology of transsexuality.It focuses on the American context and on the leading warrior in this battle: Milton Diamond, now a most prominent figure in professional debates about the clinical management of intersexuality, and the intersex person's best friend. Persons with an intersexed or transsexual condition consider, not their gonads, but their brains, their core sense of self, as the primary determinant of sex. (Diamond and Beh 2005, 6-7, note 1)

Creativity and the schizophrenia spectrum unveiled : the similarities and the differences

This study examined the commonalities and the differences between creativity and the schizophrenia spectrum. The variables measured as potential commonalities and differences were creativity, schizotypy, cognitive inhibition, spatial ability, balancing skills, positive and negative presence, absorption, mystical experiences, childhood abuse, and neuroticism. Three community groups were recruited, consisting of 31 artists, 10 people with schizophrenia, and 31 comparisons matched for gender and age with the artists. A larger student group consisting of 102 students was also recruited in order to examine the correlations among the same variables within a larger, more normative, group. The largest commonality between the artist and the schizophrenic groups, who represented the extreme end of the schizophrenia spectrum, was the propensity to mystical experiences. The greatest differences between the artist and the schizophrenic groups were that the artists were higher in creativity, performed better on spatial abilities, had better balance, had more positive states of presence, and were lower in neuroticism than the schizophrenic group. In the student group, creativity was correlated with spatial ability, positive presence, absorption, and mystical experiences. In addition, creativity was significantly related to two facets of schizotypy, unusual experiences and impulsive nonconformity. In other words, students high in certain facets of schizotypy, who may share certain characteristics with those who have schizophrenia, are higher in creativity, but people who are on the extreme end of the schizophrenia spectrum, who have been diagnosed with schizophrenia, are not. The differences between the artist and schizophrenic groups on spatial ability, balance, sense of presence, and neuroticism may help to determine whether mystical experiences help to integrate creative work or destabilize and disorganize the sense of self. It may be that mystical experiences can be used more positively by the creative individuals than people with schizophrenia, in that artists and people high in creativity were higher in positive traits such as positive presence and lower on negative variables such as neuroticism, and introvertive anhedonia.

Pratiques traditionnelles chez les sages-femmes autochtones du Nunavik et programme de formation

Les communautés inuites de la Baie d’Hudson au Nunavik (Québec) se distinguent des autres communautés autochtones par leur réappropriation des naissances depuis 1986 et par la création d’un programme de formation de sages-femmes locales. Cela a permis de mettre un terme à une longue période de transfert des femmes pour accouchement en structure hospitalière, à des kilomètres de leur village. De plus, ce programme a pour objectif de réintégrer les pratiques traditionnelles au sein d’une obstétrique moderne afin d’offrir aux femmes des services de qualité et culturellement appropriés. Le but de notre étude était d’établir si le programme de formation de sages-femmes autochtones du Nunavik a permis de concilier ces deux approches d’enseignement différentes : l’une axée sur le savoir traditionnel, et l’autre concernant les normes de qualité de soins à respecter. Une méthode de recherche qualitative a été adoptée et les données ont été recueillies à l’aide d’entrevues réalisées auprès de cinq sages-femmes inuites et de six étudiantes sages-femmes du programme de formation du Nunavik, au sein des trois villages de la Baie d’Hudson pourvus de centre de naissances. L’analyse qualitative des données ne permet pas de confirmer la réintégration du savoir traditionnel dans la pratique des sages-femmes autochtones. Les résultats révèlent, en effet, une rareté des pratiques traditionnelles connues et/ou utilisées par celles-ci (notamment l’utilisation de plantes ou de remèdes médicinaux, les postures d’accouchement, les manœuvres obstétricales, etc) en relation avec la période périnatale. Les croyances ou codes de conduite à respecter pendant la grossesse semblent bénéficier d’une meilleure transmission, mais ne font plus l’unanimité au sein des communautés. Concernant le volet de l’obstétrique moderne, le programme de formation semble conforme aux exigences actuelles occidentales, étant reconnu par l’Ordre des sages-femmes du Québec depuis septembre 2008. De plus, les sages-femmes et les étudiantes sont conscientes de la nécessité de recevoir une formation de qualité. Elles aimeraient bénéficier d’une plus grande rigueur dans l’enseignement théorique ainsi que d’une meilleure continuité du processus d’apprentissage. La difficulté retrouvée dans la mixité de l’enseignement de ces deux savoirs (traditionnel et moderne) semble donc être liée plus particulièrement au savoir traditionnel. Les sages-femmes et étudiantes inuites souhaitent protéger et promouvoir leur patrimoine culturel, mais plus dans une optique de responsabilité communautaire que dans le cadre d’un programme de formation. Une collaboration entre les volontés des communautés concernant la réintégration de ce patrimoine et la réalité actuelle de la biomédecine demeure primordiale pour continuer à garantir la sécurité et la qualité des services dispensés.

Flexibilité des pratiques de gestion des ressources humaines et intention de quitter des salariés.

Cette recherche s’intéresse au concept de la GRH à la carte et à son influence sur l’intention de départ des salariés. Pour ce faire, nous avons dû définir les différentes composantes qui entourent notre concept principal, nous faisons référence aux espaces de choix relatifs à l’organisation et à l’aménagement du temps de travail, aux espaces de choix relatifs à la rémunération, à la formation, etc. Dans leur description, ces pratiques qu’on trouve au coeur du concept de la GRH à la carte nous permettent de prendre conscience que la gestion des ressources humaines connaît une nouvelle facette. Celle-ci s’explique principalement par le souci des entreprises d’aujourd’hui de se rapprocher des attentes de leurs salariés, en leur offrant un certain nombre d’espaces de choix dans leur emploi. Les gestionnaires des ressources humaines parlent alors de personnalisation des pratiques des RH, ce qui exige une certaine flexibilité de la part des organisations. Ainsi, l’élaboration de notre étude nous a permis de présenter un modèle théorique dont l’objectif est de tester l’influence de la flexibilité des différents espaces de choix de la GRH à la carte sur l’intention de départ souvent manifestée par les salariés. Les résultats obtenus à l’aide de l’analyse multivariée appliquée à des données d’une institution bancaire haïtienne mettent en évidence l’impact significatif de certaines pratiques et le rôle médiateur du sentiment d’autodétermination dans la décision des salariés. Mots clés : Intention de départ volontaire, flexibilité des pratiques de la GRH à la carte, sentiment d’auto-détermination

Regard sur le projet migratoire et d’intégration et sur le processus identitaire de jeunes réfugiés au Québec

Cette recherche qualitative de type exploratoire tente, à l'aide du discours de jeunes réfugiés, de comprendre de quelle manière leur parcours migratoire contribue à leur projet d'intégration et identitaire, notamment en saisissant leurs perceptions de leur situation actuelle, leurs rapports avec différents réseaux sociaux, l'impact de leur statut identitaire sur leur insertion scolaire, l'impact de leur statut d’immigrant sur les relations intrafamiliales comme sur leurs choix de relations avec les pairs et leur vision de leur futur. De plus, le but de ce mémoire est de poser un regard sur la mise en place de différentes formes de stratégies identitaires au sein de divers réseaux d'appartenance locaux ou transnationaux (école, religion, organismes communautaires, etc.). Afin de mieux comprendre cette réalité, encore peu traitée au Québec, de jeunes réfugiés âgés entre 15 et 21 ans ont été sollicités pour prendre la parole lors de deux entrevues semi-dirigées. Les données résultant des entrevues mettent en évidence une singularité des cas. Malgré tout, quelques tendances semblent ressortir dans le projet migratoire et d’intégration, tels que des trajectoires migratoires empreintes d’événements douloureux, des défis dans le parcours social et scolaire au Québec et une capacité à surmonter l’adversité dans des situations de contraintes répétitives.

Le corps fantomatique dans Le Ravissement de Lol V. Stein de Marguerite Duras et La Maison étrangère d'Élise Turcotte

Depuis la valorisation du corps comme site identitaire et comme langage autre dans la théorisation de l’écriture au féminin des années 1970, les représentations du corps, notamment du corps féminin, occupent la scène romanesque jusqu’à aujourd’hui. Dans cette perspective, le présent mémoire s’intéresse au corps fantomatique des héroïnes du Ravissement de Lol V. Stein de Marguerite Duras et de La Maison étrangère d’Élise Turcotte. Le corps se fait littéralement hantise chez Duras et Turcotte : il est marqué d’absence, d’étrangeté, de fatigue et d’errance, ne trouvant plus de lieu d’être ni de repères à la suite d’un événement « traumatique », dans le cas de Lol, ou à la suite d’une séparation, dans celui d’Élisabeth. Les protagonistes sont sous l’emprise d’un sentiment d’étrangeté qui spectralise le corps en introduisant un décalage dans le rapport à soi et à autrui. Ce sentiment est causé en partie par une mémoire défaillante qui fragmente leur identité. C’est par un travail mémoriel que Lol V. Stein et Élisabeth tenteront de résoudre la hantise de leur histoire individuelle et familiale. Le texte fait écho à la corporalité fantomatique – mise en scène selon diverses représentations du corps dématérialisé – en se spectralisant à son tour par l’inscription des « blancs » dans l’écriture. Le processus d’effacement des corps sera mis en parallèle avec une spatio-temporalité elle aussi marquée par la hantise du passé. La spectralité apparaît, dans le récit contemporain au féminin, pour témoigner d’une identité (cor)rompue par la rupture ; celle-ci devient prétexte à une réflexion sur la manière d’habiter son corps et d’un être-au-monde à repenser.

Quête spirituelle et réconciliation identitaire : une ethnographie de la Communauté des druides du Québec

Au cours du vingtième siècle, le Québec a connu un bouleversement identitaire et religieux lorsqu’une majorité de Québécois a délaissé les prescriptions doctrinales catholiques, la religion identitaire du Québec, qui encadrait leur vie et s’imposait en tant que détentrice du « code exclusif du sens » (Hervieu-Léger 1993 : 155). Pour combler la perte de repères (Lemieux 2008) engendrée par les bouleversements décrits précédemment, plusieurs individus se tournèrent vers d’autres formes de spiritualité, soit en se convertissant à un nouveau système religieux ou en s’engageant dans une quête spirituelle. Certains Québécois, au cours de leur quête, ont alors découvert le druidisme, une spiritualité fondée sur le désir de retour à l’ancienne religion païenne des Celtes, et l’ont intégré en tant que composante principale ou secondaire de leur spiritualité. Le but de ce mémoire sera d’apporter quelques éléments d’explication à la présence du druidisme au Québec. Nous soulignerons l’importance du contexte moderne dans la quête de sens amorcée par l’adepte de paganisme celte, car ce contexte semble avoir servi de catalyseur dans le processus de découverte du druidisme pour ces Québécois. Puis, nous mettrons l’accent sur les raisons identitaires mises de l’avant par la CDQ pour justifier leur choix d’intégrer le druidisme à leur cheminement spirituel. Nous verrons que pour le druidisant, cette religion vient à la fois répondre à des besoins spirituels et combler un vide identitaire.
