El autocuidado y apoyo social de mujeres de un proyecto de seguimiento mamográfico en Porto Alegre/Brasil

Objective: Identify preventive self-care practices and analyze the configurations of the network support for women with and without breast cancer registered in a mammography-monitoring project from Porto Alegre/Brazil.Method: a mixed sequential delimitation was performed, which expanded the results of the quantitative step (cross and correlation section) in a qualitative step (narrative interviews). 37 women diagnosed with breast cancer (group 1) and 72 without this diagnosis (group 2 – monitoring) participated. The following instruments were used: Assessment Questionnaire Self-care Ability (ASA-A) and Assessment Questionnaire Perceived Social Support and Community. There were performed descriptive analysis and comparison of means (t test and ANOVA) between the two groups. To deepen the understanding of the data, we selected four women with breast cancer with extreme levels on the scale of Social Support to participate in the biographical narrative interviews.Results: the analysis indicate that women who had breast cancer have better self-care practices than the women from the monitoring project (t = 1.791, P = 0.027). As for the analysis of social support, there were no statistically significant differences between the two groups. All participants have an average level of perceived social and community support. It was highlighted by the qualitative data that it was after the diagnosis of breast cancer that women lived self-care aspects they had not previously experienced.Conclusions: the self-care was significantly bigger in the group of women with breast cancer, where the cancer diagnosis was a trigger to increase self-care.

Receptive Vocabulary of CLIL and Non-CLIL Primary and Secondary School Learners

CLIL instruction has been reported to be beneficial for foreign language vocabulary learning since CLIL students show higher vocabulary profiles than students of their same age in traditional EFL contexts. However, to our knowledge, the receptive vocabulary knowledge of CLIL and non-CLIL learners at the end of primary and secondary education has not been examined yet. Hence, this study aims at comparing the receptive vocabulary size 79 CLIL primary learners with the receptive vocabulary knowledge of 331 non-CLIL learners at the end of primary and secondary school. Sex-based differences were also analysed. The 2k Vocabulary Levels Test (VLT) was used for the purposes of the study. Results revealed that learners’ receptive vocabulary sizes lie within the most frequent 1000 words, non-CLIL secondary school students throw better results than primary students but the differences between the secondary group and the CLIL group are not statistically significant. As for sex-based differences, we found no significant differences among the groups. These findings led us to believe that the CLIL approach offers a benefit for vocabulary acquisition since CLIL learners have been exposed to the foreign language for a shorter period of time and the results are quite similar to their non-CLIL secondary school partners.

Social media integration for the purpose of self-regulated learning

In this study, design based research in a teacher design team is performed. Teachers who intend to use social media to extend their school class teaching, are confronted with a lack of clear guidelines that inform them how to utilize them effectively. In this study, we aim at formulating such guidelines and testing their usefulness. First, opportunities to facilitate self-regulated learning (SRL) in higher education through the use of social media are elaborated in a literature study. Second, these opportunities are translated into teacher education to search for stimulating and limiting factors within the design, resulting in guidelines for effective social media integration.

Students’ Use of Knowledge Resources in Environmental Interaction on an Outdoor Learning Trail

This study examined how students leveraged different types of knowledge resources on an outdoor learning trail. We positioned the learning trail as an integral part of the curriculum with a pre- and post-trail phase to scaffold and to support students’ meaning-making process. The study was conducted with two classes of secondary two students. We coded two groups’ discourse to examine the use of knowledge resource types in the meaning-making process in an outdoor learning setting: contextual resource, new conceptual resource, prior knowledge resource, as well as the relationship among these knowledge resource types. Next, we also examined environmental interaction and integration in the students’ use of these knowledge resource types. Analysis showed that contextual resources are chiefly instrumental in fostering students’ capacity to harness new conceptual resource and to activate prior knowledge resource in interacting with and integrating the outdoor learning environment in the meaning-making process.

Prior knowledge transfer across transcriptional data sets and technologies using compositional statistics yields new mislabelled ovarian cell line

Here, we describe gene expression compositional assignment (GECA), a powerful, yet simple method based on compositional statistics that can validate the transfer of prior knowledge, such as gene lists, into independent data sets, platforms and technologies. Transcriptional profiling has been used to derive gene lists that stratify patients into prognostic molecular subgroups and assess biomarker performance in the pre-clinical setting. Archived public data sets are an invaluable resource for subsequent in silico validation, though their use can lead to data integration issues. We show that GECA can be used without the need for normalising expression levels between data sets and can outperform rank-based correlation methods. To validate GECA, we demonstrate its success in the cross-platform transfer of gene lists in different domains including: bladder cancer staging, tumour site of origin and mislabelled cell lines. We also show its effectiveness in transferring an epithelial ovarian cancer prognostic gene signature across technologies, from a microarray to a next-generation sequencing setting. In a final case study, we predict the tumour site of origin and histopathology of epithelial ovarian cancer cell lines. In particular, we identify and validate the commonly-used cell line OVCAR-5 as non-ovarian, being gastrointestinal in origin. GECA is available as an open-source R package.

Development of sustainable, innovative and energy-efficient concrete, based on the integration of all-waste materials: SUS-CON panels for building applications

The building sector requires the worldwide production of 4 billion tonnes of cement annually, consuming more than 40% of global energy and accounting for about 8% of the total CO2 emissions. The SUS-CON project aimed at integrating waste materials in the production cycle of concrete, for both ready-mixed and pre-cast applications, resulting in an innovative light-weight, ecocompatible and cost-effective construction material, made by all-waste materials and characterized by enhanced thermal insulation performance and low embodied energy and CO2. Alkali activated “cementless” binders, which have recently emerged as eco-friendly construction materials, were used in conjunction with lightweight recycled aggregates to produce sustainable concrete for a range of applications. This paper presents some results from the development of a concrete made with a geopolymeric binder (alkali activated fly ash) and aggregate from recycled mixed plastic. Mix optimisation was achieved through an extensive investigation on production parameters for binder and aggregate. The mix recipe was developed for achieving the required fresh and hardened properties. The optimised mix gave compressive strength of about 7 MPa, flexural strength of about 1.3 MPa and a thermal conductivity of 0.34 W/mK. Fresh and hardened properties were deemed suitable for the industrial production of precast products. Precast panels were designed and produced for the construction of demonstration buildings. Mock-ups of about 2.5 x 2.5 x 2.5 m were built at a demo park in Spain both with SUS-CON and Portland cement concrete, monitoring internal and external temperatures. Field results indicate that the SUS-CON mock-ups have better insulation. During the warmest period of the day, the measured temperature in the SUS-CON mock-ups was lower.

Sustainable solutions for the construction sector: integration of secondary raw materials in the production cycle of concrete

The construction industry is one of the largest consumers of raw materials and energy and one of the highest contributor to green-houses gases emissions. In order to become more sustainable it needs to reduce the use of both raw materials and energy, thus lim-iting its environmental impact. Developing novel technologies to integrate secondary raw materials (i.e. lightweight recycled aggre-gates and alkali activated “cementless” binders - geopolymers) in the production cycle of concrete is an all-inclusive solution to im-prove both sustainability and cost-efficiency of construction industry. SUS-CON “SUStainable, Innovative and Energy-Efficiency CONcrete, based on the integration of all-waste materials” is an European project (duration 2012-2015), which aim was the inte-gration of secondary raw materials in the production cycle of concrete, thus resulting in innovative, sustainable and cost-effective building solutions. This paper presents the main outcomes related to the successful scaling-up of SUS-CON concrete solutions in traditional production plants. Two European industrial concrete producers have been involved, to design and produce both pre-cast components (blocks and panels) and ready-mixed concrete. Recycled polyurethane foams and mixed plastics were used as aggre-gates, PFA (Pulverized Fuel Ash, a by-product of coal fuelled power plants) and GGBS (Ground Granulated Blast furnace Slag, a by-product of iron and steel industries) as binders. Eventually, the installation of SUS-CON concrete solutions on real buildings has been demonstrated, with the construction of three mock-ups located in Europe (Spain, Turkey and Romania)

La persévérance scolaire des immigrants haïtiens de première génération au Québec et à New York

Le but de cette thèse a consisté à comprendre les facteurs de la persévérance et de l’abandon scolaire des nouveaux arrivants haïtiens au Québec et à New York. La recension d’écrits a révélé une sous-documentation de la thématique en question. Toutefois, l’élaboration du cadre conceptuel nous a permis de mieux cerner la problématique, d’analyser et de synthétiser plusieurs approches théoriques dont les théories du rendement scolaire des immigrants (Rong et Brown, 2001 ; Warikoo et Carter, 2009 ; Xie et Greenman, 2011), l’approche bourdieusienne des capitaux (1979a, 1979b, 1980), le structuro-fonctionnalisme de Merton (1965) et le courant effets-écoles/ effets-enseignants (Crahay, 2000 ; Bressoux, 1994a). Nous avons également mis en évidence deux approches compréhensives à savoir l’interactionnisme (Weber, 1959 ; Boudon, 1979, 1994 ; Goffman, 1998 ; Garfinkel, 1967) et l’approche du rapport au savoir de l’équipe ESCOL (Rochex, 2002 ; Charlot, 2003) dans l’objectif de faire valoir le caractère relatif des conclusions d’une recherche qualitative qui priorise la subjectivité des participants dans l’analyse des faits sociaux. Dans cette recherche, nous avons interviewé onze participants à Montréal et à Brooklyn, parmi lesquels sept hommes et quatre femmes. Ils ont tous une expérience d’abandon scolaire au secondaire ou au secteur des adultes. Nous avons utilisé l’entretien semi-dirigé comme méthode de collecte d’information et l’analyse thématique est celle de l’analyse des données. L’analyse des données nous a permis de classer les informations fournies par les participants en cinq rubriques : capital économique, capital culturel, capital social, encadrement institutionnel et facteurs spécifiques. Ces cinq rubriques regroupent les facteurs de la persévérance et du décrochage scolaire évoqués par les participants de la recherche. La réalisation de cette thèse nous apporte un bon éclairage quant à notre tentative de comprendre la dynamique de l’abandon scolaire des jeunes et des jeunes adultes immigrants haïtiens de première génération au Québec et à New York, au secondaire et au secteur de l’éducation des adultes. Nous avons mis en relation les résultats de la recherche avec ceux des travaux que nous avons recensés dans la problématique et dans le cadre conceptuel de cette thèse. La synthèse de ces résultats nous a amené à faire une proposition d’éléments d’un modèle d’analyse que nous qualifions de « relance scolaire des nouveaux arrivants haïtiens au Québec et à New York ». L’analyse et la synthèse des facteurs émergents de la recherche, plus précisément des six thèmes qui composent la rubrique des facteurs spécifiques : facteurs démographiques, motivation personnelle, lacunes de base, facteurs affectifs, traits de personnalité et problèmes de comportement, nous ont permis d’élaborer un autre concept qui peut représenter une grande contribution à la persévérance scolaire des nouveaux arrivants haïtiens. Il s’agit de l’encadrement psycho-intégrationnel qui est une forme d’accompagnement dont les jeunes et les jeunes adultes nouveaux arrivants haïtiens pourront être bénéficiaires au début en vue d’un bon démarrage sur le plan socioéducatif et de leur persévérance scolaire au pays d’accueil. L’encadrement psycho-intégrationnel, consistera à mettre en relation certains faits psychologiques qui ont marqué la vie pré-migratoire des élèves jeunes et jeunes adultes d’origine haïtienne avec les faits sociaux qui peuvent influencer leur vie au pays d’accueil. C’est une forme d’assistance individuelle dont l’État, les institutions sociales d’intégration et l’école constitueront les principales structures de matérialisation. Les principaux intervenants, notamment les psychologues, les travailleurs sociaux et les anthropo-sociologues se chargeront de comprendre et d’orienter les nouveaux arrivants quant au nouveau comportement à adopter pour une meilleure évolution sur les plans socio-culturel, professionnel et économique. Mots clés : Persévérance scolaire, relance scolaire, immigrants haïtiens, première génération, nouveaux arrivants.

Learning from one another: evaluating the impact of horizontal knowledge exchange for environmental management and governance

There is increasing advocacy for inclusive community-based approaches to environmental management, and growing evidence that involving communities improves the sustainability of social-ecological systems. Most community-based approaches rely on partnerships and knowledge exchange between communities, civil society organizations, and professionals such as practitioners and/or scientists. However, few models have actively integrated more horizontal knowledge exchange from community to community. We reflect on the transferability of community owned solutions between indigenous communities by exploring challenges and achievements of community peer-to-peer knowledge exchange as a way of empowering communities to face up to local environmental and social challenges. Using participatory visual methods, indigenous communities of the North Rupununi (Guyana) identified and documented their community owned solutions through films and photostories. Indigenous researchers from this community then shared their solutions with six other communities that faced similar challenges within Guyana, Suriname, Venezuela, Colombia, French Guiana, and Brazil. They were supported by in-country civil society organizations and academics. We analyzed the impact of the knowledge exchange through interviews, field reports, and observations. Our results show that indigenous community members were significantly more receptive to solutions emerging from, and communicated by, other indigenous peoples, and that this approach was a significant motivating force for galvanizing communities to make changes in their community. We identified a range of enabling factors, such as building capacity for a shared conceptual and technical understanding, that strengthens the exchange between communities and contributes to a lasting impact. With national and international policy-makers mobilizing significant financial resources for biodiversity conservation and climate change mitigation, we argue that the promotion of community owned solutions through community peer-to-peer exchange may deliver more long-lasting, socially and ecologically integrated, and investment-effective strategies compared to top-down, expert led, and/or foreign-led initiatives.

Farmers’ knowledge and use of soil fauna in agriculture: a worldwide review

General knowledge of the small, invisible, or hidden organisms that make soil one of the most biodiverse habitats on Earth is thought to be scarce, despite their importance in food systems and agricultural production. We provide the first worldwide review of high-quality research that reports on farmers’ knowledge of soil organisms in agriculture. The depth of farmers’ knowledge varied; some farming communities held detailed local taxonomies and observations of soil biota, or used soil biological activity as indicators of soil fertility, while others were largely unaware of soil fauna. Elicitation of soil biota knowledge was often incidental to the main research goal in many of the reviewed studies. Farmers are rarely deliberately or deeply consulted by researchers on their existing knowledge of soil biota, soil ecology, or soil ecological processes. Deeper understanding of how farmers use and value soil life can lead to more effective development of collaborative extension programs, policies, and management initiatives directed at maintaining healthy, living soils.

"It’s just very natural" – interpersonal knowledge as a didactical device in guided classroom conversations in religious education

This article investigates how teachers in religious education (RE) think and act as professionals while working with differences in religious and philosophy of life experiences and beliefs in class and trying to do this in respectful and inclusive ways. It analyses data from two research projects that were carried out in lower secondary school in Norway. The main research question is: What is the relationship between teachers’ contextual knowledge and knowledge of the child and how do these two dimensions of professional knowledge interact when religious education teachers try to strike a good balance between inclusion and productive learning in their teaching practice? The data analysed were drawn from three different data sets featuring three Norwegian religious education-teachers. The research was part of the EU-funded "REDCo"-project and the "Religious education and diversity" - project ["ROM"] funded by the Norwegian Research Council. The interviewees emphasized the potential of the religious education subject to contribute to a wider tolerance for difference and to support individual students in their identity management. The analysis shows, however, that considerable contextual awareness - of the classroom and of the local community - is needed to realize this potential. It also shows the importance of interpersonal knowledge between the teacher and each student if contextual awareness is to be effective in terms of inclusion, participation, wellbeing and good learning outcomes for all students.

Federated architecture for biomedical data integration

The last decades have been characterized by a continuous adoption of IT solutions in the healthcare sector, which resulted in the proliferation of tremendous amounts of data over heterogeneous systems. Distinct data types are currently generated, manipulated, and stored, in the several institutions where patients are treated. The data sharing and an integrated access to this information will allow extracting relevant knowledge that can lead to better diagnostics and treatments. This thesis proposes new integration models for gathering information and extracting knowledge from multiple and heterogeneous biomedical sources. The scenario complexity led us to split the integration problem according to the data type and to the usage specificity. The first contribution is a cloud-based architecture for exchanging medical imaging services. It offers a simplified registration mechanism for providers and services, promotes remote data access, and facilitates the integration of distributed data sources. Moreover, it is compliant with international standards, ensuring the platform interoperability with current medical imaging devices. The second proposal is a sensor-based architecture for integration of electronic health records. It follows a federated integration model and aims to provide a scalable solution to search and retrieve data from multiple information systems. The last contribution is an open architecture for gathering patient-level data from disperse and heterogeneous databases. All the proposed solutions were deployed and validated in real world use cases.

Transportation of Children in Ground Ambulances: Professionals' Knowledge and Safety Measures

Background: The transport of children in ground ambulances is a rarely studied topic worldwide. The ambulance vehicle is a unique and complex environment with particular challenges for the safe, correct and effective transportation of patients. Unlike the well developed and readily available guidelines on the safe transportation of a child in motor vehicles, there is a lack on consistent specifications for transporting children in ambulances. Nurses are called daily to transfer children to hospitals or other care centers, so safe transport practices should be a major concern. Purpose: to know which are the safety precautions and specific measures used in the transport of children in ground ambulances by nurses and firefighters and to identify what knowledge these professionals had about safe modes of children transportation in ground ambulances. Methods: In this context, an exploratory - descriptive study and quantitative analysis was conducted. A questionnaire was completed by 135 nurses and firefighters / ambulance crew based on 4 possible children transport scenarios proposed by the NHTSA (National Highway Traffic Safety Administration) and covered 5 different children´s age groups (new born children, 1 to 12 months; 1 to 3 years old; 4 to 7 years old and 8 to 12 years old). Results: The main results showed a variety of safety measures used by the professionals and a significant difference between their actual mode of transportation and the mode they consider to be the ideal considering security goals. In addition, findings showed that achieved scores related to what ambulance crews do in the considered scenarios reflect mostly satisfactory levels of transportation rather than optimum levels of safety, according to NHTSA recommendations. Variables as gender, educational qualifications, occupational group and local where professionals work seem to influence the transport options. Female professionals and nurses from pediatric units appear to do a safer transportation of children in ground ambulances than other professionals. Conclusion: Several professionals refereed unawareness of the safest transportation options for children in ambulances and did not to know the existence of specific recommendations for this type of transportation. The dispersion of the results suggests the need for investment in professional training and further regulation for this type of transportation.
