L’environnement de naissance : saisir l’expérience d’accouchement en maison de naissance

L’aménagement des maisons de naissance est actuellement en hausse sur le territoire québécois, pour répondre à la forte demande des femmes pour un service sage‐femme et également pour répondre au désir des femmes de donner naissance dans un milieu alternatif à l’hôpital ou à la maison. La problématique consiste à s’interroger sur la pertinence de l’environnement actuel des maisons de naissance, à savoir s’il soutient les besoins des femmes qui y donnent naissance, mais également si cet environnement affecte l’expérience d’accouchement des femmes, dans le but futur que les maisons de naissance soient parfaitement adaptées aux nécessités des femmes qui y accouchent. Cette problématique, axée sur la relation personne‐environnement avec point d’ancrage l’expérience sensible de l’usagère, est adressée en premier lieu par une analyse critique des maisons de naissance de Montréal, puis en analysant le discours des femmes, recueillis sous forme d’entretiens semi‐dirigés, pour en exprimer l’expérience d’accouchement en ces lieux. Se basant sur les principes d’études en relations personnes‐environnement, cette recherche vise ainsi à saisir les besoins relatifs au lieu de naissance à travers l’expérience sensible de la femme et des liens affectifs que tisse celle‐ci avec l’environnement lors de son accouchement, plus particulièrement au sein des maisons de naissance. Cette recherche vise également à saisir comment, à l’inverse, l’environnement de naissance affecte l’expérience de la femme lorsqu’elle donne naissance. Parmi les constats de cette recherche, nous réalisons que l’environnement affecte l’expérience d’accouchement dans une certaine mesure et qu’il aurait avantage à se faire des plus discret, afin de ne pas affecter la concentration des femmes durant leur travail. Cette « bulle » que les femmes se forment durant l’accouchement s’avère très importante dans le bon déroulement de la naissance; l’environnement devrait permettre et la mise en place de cette « bulle » et sa continuité jusqu’à la naissance de l’enfant. La poursuite des recherches sur le sujet pourrait entre autres mener à un modèle d’aménagement non rigide pour les maisons de naissance et pourrait également contribuer à l’amélioration des maisons de naissance existantes ainsi que celles à venir.

Aprender a cuidar em enfermagem: do diálogo reflexivo aos significados : perspectiva do estudante da licenciatura

Este estudo tem como tema central a „vivência de aprender a cuidar sendo cuidado‟ na formação inicial em enfermagem. A conjugação, sistemática e contínua, de estratégias baseadas no princípio da realidade e da relação dialógica enquadram a pertinência de compreender o fenómeno da vivência de aprender a cuidar. Um dispositivo pedagógico inovador, fundamentado no Teoria Humanista de Enfermagem de Paterson & Zderad, foi desenvolvido nos anos lectivos 2005/2006 e 2006/2007 desde a teoria à prática clínica, na Unidade Curricular Enfermagem Pediátrica, em que participaram 86 estudantes do 3º ano. O estudo de investigação, com uma abordagem qualitativa, foi elaborado a partir da participação de 12 sujeitos paradigmáticos oriundos das três comunidades de aprender, que realizaram reflexões individuais, diários de aprendizagem e portefólios, instrumentos nos quais registaram as descrições significativas. Estas foram submetidas a análise qualitativa, com os critérios propostos pelo Método Fenomenológico conjugados com os de Van Manen, que nos permitiu identificar e relacionar semelhanças e idiossincrasias nas comunidades de aprender. Emergiram treze temas: tempo; lugar; consciência do outro; autoconhecimento; auto-realização; reciprocidade; abertura; responsabilidade; respeito; confiança interpessoal; ligação; competência no cuidar e compreensão do aprender. Concluímos que um dispositivo pedagógico fundamentado nesta teoria promove o desenvolvimento pessoal e profissional do estudante quando conjugada com as estratégias seleccionadas e potencia o acto de cuidar sensível. A congruência, sistematização e continuidade de uma matriz pedagógica construtivista e humanista (re)coloca a centralidade no ser humano, levando-nos a recomendar a sua implementação no ensino de enfermagem.

Contribution of Genetic Background, Traditional Risk Factors, and HIV-Related Factors to Coronary Artery Disease Events in HIV-Positive Persons

Background Persons infected with human immunodeficiency virus (HIV) have increased rates of coronary artery disease (CAD). The relative contribution of genetic background, HIV-related factors, antiretroviral medications, and traditional risk factors to CAD has not been fully evaluated in the setting of HIV infection. Methods In the general population, 23 common single-nucleotide polymorphisms (SNPs) were shown to be associated with CAD through genome-wide association analysis. Using the Metabochip, we genotyped 1875 HIV-positive, white individuals enrolled in 24 HIV observational studies, including 571 participants with a first CAD event during the 9-year study period and 1304 controls matched on sex and cohort. Results A genetic risk score built from 23 CAD-associated SNPs contributed significantly to CAD (P = 2.9×10−4). In the final multivariable model, participants with an unfavorable genetic background (top genetic score quartile) had a CAD odds ratio (OR) of 1.47 (95% confidence interval [CI], 1.05–2.04). This effect was similar to hypertension (OR = 1.36; 95% CI, 1.06–1.73), hypercholesterolemia (OR = 1.51; 95% CI, 1.16–1.96), diabetes (OR = 1.66; 95% CI, 1.10–2.49), ≥1 year lopinavir exposure (OR = 1.36; 95% CI, 1.06–1.73), and current abacavir treatment (OR = 1.56; 95% CI, 1.17–2.07). The effect of the genetic risk score was additive to the effect of nongenetic CAD risk factors, and did not change after adjustment for family history of CAD. Conclusions In the setting of HIV infection, the effect of an unfavorable genetic background was similar to traditional CAD risk factors and certain adverse antiretroviral exposures. Genetic testing may provide prognostic information complementary to family history of CAD.

NARRATIVAS DE EXPERIÊNCIAS VIVIDAS POR DOCENTES E DISCENTES COM USO DE TECNOLOGIA DE INFORMAÇÃO E COMUNICAÇÃO – TDIC NA EDUCAÇÃO BÁSICA

Vivemos um período de transformações políticas, econômicas, sociais e culturais que, a todo instante, nos impõe desafios. Neste contexto, nas últimas décadas, o uso da tecnologia tem sido ampliado na realização de diversas atividades cotidianas, na divulgação de informações, na comunicação, como forma de expressão e organização da sociedade. A escola, enquanto instituição social, precisa reconhecer esta nova realidade, esta diferente possibilidade de aquisição e transformação de saber, para que possa intervir, ressignificar e redirecionar sua ação, a fim de atender as demandas de seu tempo. O objetivo geral desta pesquisa, a partir da apresentação e análise de experiências realizadas com o uso de Tecnologias da Informação e Conhecimento, é o de refletir sobre como inserir estas ferramentas no processo de ensinar e aprender na escola a partir da visão de professores e alunos, visando a formação integral do educando. Deste modo, no desenvolvimento, entendemos como necessário conhecer e considerar o contexto histórico, bem como as perspectivas relacionadas a escola e seus protagonistas (professores e estudantes) na chamada Sociedade da Informação e do Conhecimento. Ressaltamos a importância do docente (sua formação) e seu papel de mediador nos processos de aprendizagem, assim como a recepção à tecnologia, observando função e espaço de atuação desta. Destacamos experiências com a utilização de TDIC, realizada por professores e alunos, como a produção de game, revistas científicas, escrita de histórias, produções artísticas, blogs, vlogs, discussões em grupos presentes em redes sociais. A metodologia utilizada nesta pesquisa é qualitativa, na modalidade de pesquisa-ação e narrativa, em função do envolvimento com o grupo e com as atividades desenvolvidas, nas quais os participantes compartilham com o pesquisador suas histórias pessoais e de aprendizagem relacionadas às ações ou às atividades que realiza, fornecendo informações e indícios relevantes sobre o seu processo de formação ao longo do tempo. A revisão de literatura foi realizada por meio de análise bibliográfica e documental em livros, teses, dissertações, periódicos específicos sobre o assunto, além de artigos publicados na Internet. A coleta de dados foi realizada a partir de conversas informais, entrevistas semiestruturadas e filmagem dos relatos. A análise foi realizada a partir da abordagem hermenêutico-fenomenológica, que busca descrever e interpretar fenômenos da experiência humana, a fim de investigar a essência por meio da identificação de temas. Os resultados apontam para a necessidade e possibilidade da ampliação da utilização de TDIC como recurso no processo de ensino e aprendizagem, por meio de formação, diálogo, interação, intencionalidade, expectativas, esperança e seus desdobramentos.

The teacher portfolio as a vehicle for reflective practice

This qualitative case study was limited to an eighteen-hour workshop on “Constructing a Reflective Teacher Portfolio.” The study was conducted at the Nova Center, a research and development school, in the Broward County Public School System. Six participants took part in the study. The study examined the process used by the participants as they constructed their portfolios, explored the reflective aspect of their construction, and investigated the impact that constructing a portfolio had on them and their work. ^ Data was gathered using interviews, observations, and artifacts. Content analysis and the combined frameworks of Van Manen (1977), Smyth (1989), and Pugach and Johnson (1990) were used to examine the data. The data indicates that the portfolios and workshop were not as effective as anticipated in encouraging the participants to examine their work. The following themes emerged as a result of this study: (a) teachers begin constructing their portfolios by gathering material that represents past successes; (b) examining philosophies of education, writing a personal narrative and sharing with colleagues stimulates reflective practice; (c) teachers have difficulty expressing their personal beliefs about education; (d) creating a reflective portfolio is a constructivist process that encourages divergent products; (e) teachers initially do not recognize a strong connection between constructing a portfolio and improving their work; and (f) constructing a portfolio may be an inside-out approach to educational reform. ^ Recommendations were presented to improve the workshop, specifically focusing on teachers examining their practices and learning from students' work. Additional study is needed to evaluate the influence of these changes in the workshop. ^

A hermeneutic phenomenology of graduate education students' understandings of instructor power in a higher education classroom

Higher education is a distribution center of knowledge and economic, social, and cultural power (Cervero & Wilson, 2001). A critical approach to understanding a higher education classroom begins with recognizing the instructor's position of power and authority (Tisdell, Hanley, & Taylor, 2000). The power instructors wield exists mostly unquestioned, allowing for teaching practices that reproduce the existing societal patterns of inequity in the classroom (Brookfield, 2000). ^ The purpose of this hermeneutic phenomenological study was to explore students' experiences with the power of their instructors in a higher education classroom. A hermeneutic phenomenological study intertwines the interpretations of both the participants and the researcher about a lived experience to uncover layers of meaning because the meanings of lived experiences are usually not readily apparent (van Manen, 1990). Fifteen participants were selected using criterion, convenience, and snowball sampling. The primary data gathering method were semi-structured interviews guided by an interview protocol (Creswell, 2003). Data were interpreted using thematic reflection (van Manen, 1990). ^ Three themes emerged from data interpretation: (a) structuring of instructor-student relationships, (b) connecting power to instructor personality, and (c) learning to navigate the terrains of higher education. How interpersonal relationships were structured in a higher education classroom shaped how students perceived power in that higher education classroom. Positive relationships were described using the metaphor of family and a perceived ethic of caring and nurturing by the instructor. As participants were consistently exposed to exercises of instructor power in a higher education classroom, they attributed those exercises of power to particular instructor traits rather than systemic exercises of power. As participants progressed from undergraduate to graduate studies, they perceived the benefits of expertise in content or knowledge development as secondary to expertise in successfully navigating the social, cultural, political, and interpersonal terrains of higher education. Ultimately, participants expressed that higher education is not about what you know; it is about learning how to play the game. Implications for teaching in higher education and considerations for future research conclude the study.^

Island diasporas: Perceptions of Indo-Caribbean protégés regarding the effects of their cross-cultural mentoring experiences in the United States

Mentoring is defined as an "intense caring relationship in which persons with more experience work with less experienced persons to promote both professional and personal development" (Caffarella, 1992, p. 38). It is "a powerful emotional, and passionate interaction whereby the mentor and protégé experience...intellectual growth and development" (Galbraith & Zelenak, 1991, p. 126). In cross-cultural mentoring, mentors and protégés from different cultures confront social and cultural identities, goals, expectations, values, and beliefs (Cross & Lincoln, 2005) to "achieve a higher level of potency in education and society" (Mullen, 2005, p. 6). Cross-cultural mentoring research explores attitudes, behaviors, linguistics and motivators of the more visible racial and ethnic groups in the U.S. (Elmer, 1986, Ulmer, 2008). The cross-cultural mentoring experiences of Indo-Caribbeans in the U.S. are obscured from the research despite their rich socio-historic culture. The purpose of this phenomenological study was to explore the perceptions of Indo-Caribbean protégés regarding the effects of their cross-cultural mentoring experiences in the United States. Phenomenology is "the systematic attempt to uncover and describe...the internal meaning structures, of lived experience [by studying the] particulars or instances as they are encountered" (Van Manen, 1990, p. 10). Criterion and snowball sampling were used to recruit 15 participants. A semi-structured interview guide was used to gather data and Creswell's (2007) simplified version of Moustakas's (1994) Modification of the Stevick-Colaizzi-Keen Method of Analysis of Phenomenological Data was used to analyze the data. Three themes emerged: (a) "Sitting at the feet of gurus" taught protégés how to accept guidance, (b) Guru-Shishya: Learning and Discipleship, ways that protégés perceived mentors' guidance related to work, skill acquisition, and social or emotional support, and (c) Samavartan sanskar: Building Coherence, helped protégés understand, manage and find meaning. Protégés' goals and professional expectations determined what they wanted from cross-cultural mentoring relationships and what they were willing to endure within those relationships. Since participants valued achievement and continuous improvement, mentor support was integral to making meaning and developing a sense of coherence in their lives. Implications regarding cross-cultural mentoring relationships together with recommendations for future research conclude the study.

Key determinants of organisational silence for non-standard workers

Purpose – The purpose of this paper is to identify the key determinants of organisational silence from the perspective of non-standard workers (NSWs). The study focuses on three research themes: first, analysing the experiences motivating NSWs to remain silent; second, analysing the role of the NSW life cycle in the motivation to remain silent, the final theme is evaluation of the impact on organisational voice of an organisation employing a workforce in which NSWs and standard workers (SWs) are blended. Design/methodology/approach – The study utilises a phenomenological approach, as defined by Van Manen (2007), to collect and analyse the phenomenon of organisational silence from the perspective of NSWs. The NSWs are defined as individuals operating via Limited Liability UK registered companies created for the purpose of delivering services to organisations via a contract of services. This study employed a combination of phenomenology and hermeneutics to collect and analyse the data collected from the NSWs using semi-structured interviews (Lindseth and Norberg, 2004). Findings – The study concludes with three core findings. NSWs experience similar motivational factors to silence as experienced by standard workers (SWs). The key differential between a SW and a NSW is the role of defensive silence as a dominant motivator for a start-up NSW. The study identified that the reasons for this is that new NSWs are defensive to protect their reputation for any future contract opportunities. In addition, organisations are utilising the low confidence of new start up NSWs to suppress the ability of NSWs to voice. The research indicates how experienced NSWs use the marketing stage of their life cycle to establish voice mechanisms. The study identified that NSWs, fulfiling management and supervisory roles for organisations, are supporting/creating climates of silence through their transfer of experiences as SWs prior to becoming NSWs. Research limitations/implications – This study is a pilot study, and the findings from this study will be carried forward into a larger scale study through engagement with further participants across a diverse range of sectors. This study has identified that there is a need for further studies on organisational silence and NSWs to analyse more fully the impact of silence on the individuals and the organisation itself. A qualitative phenomenological hermeneutical study is not intended to be extrapolated to provide broad trends. The focus of the phenomenological hermeneutic research methodology is on describing and analysing the richness and depth of the NSW’s experiences of silence in organisational settings. Originality/value – This paper draws together the studies of worker classification, motivators for organisational silence, and the impact of blending SWs and NSWs in an organisational setting. The study demonstrates that academic research to date has focused predominantly on SWs to the exclusion of the 1.5 million, and growing, NSWs in the UK. This study examines these under-represented workers to analyse the participants’ experiences of organisational silence, and its consequences in organisational settings, demonstrating a need for further studies.

Sur l’existence de solutions pour l’équation de van der Pol et pour certaines équations différentielles du second ordre, en présence d’impulsions ; sur la moyennisation pour les équations différentielles floues

Cette thèse est constituée de deux parties : Dans la première partie nous étudions l’existence de solutions périodiques, de periode donnée, et à variations bornées, de l’équation de van der Pol en présence d’impulsions. Nous étudions, en premier, le cas où les impulsions ne dépendent pas de l’état. Ensuite, nous considèrons le cas où les impulsions dépendent de la moyenne de l’état et enfin, nous traitons le cas général où les impulsions dépendent de l’état. La méthode de résolution est basée sur le principe de point fixe de type contraction. Nous nous intéressons ensuite à l’étude d’un problème avec trois points aux limites, associé à certaines équations différentielles impulsives du second ordre. Nous obtenons un premier résultat d’existence de solutions en appliquant le théorème de point fixe de Schaefer. Un deuxième résultat est obtenu en utilisant le théorème de point fixe de Sadovskii. Pour le résultat d’unicité des solutions nous appliquons, enfin, un théorème de point fixe de type contraction. La deuxième partie est consacrée à la justification de la technique de moyennisation dans le cadre des équations différentielles floues. Les conditions sur les données que nous imposons sont moins restrictives que celles de la littérature.

Diagramas de Ellingham e de Van't Hoff: algumas considerações

The main subject of this article is to show the parallelism betwen the Ellingham and Van't Hoff diagrams. The first one is a graphic representation of the changes in the standard Gibbs free energy (deltarGtheta) as a function of T and was introduced by Ellingham in 1944, in order to study metallurgic processes involving oxides and sulphides. On the other hand, the Van't Hoff diagram is a representation of the function ln K versus (1/T). The equivalence between both diagrams is easily demonstrated, making simple mathematical manipulations. In order to show the parallelism between both diagrams, they are presented briefly and two examples are discussed. The comparison of the both diagrams surely will be helpful to students and teachers in their learning and teaching activities, and will certainly enrich important aspects of chemical thermodynamics.
