Gènere i immigració en les narratives visuals de les noies dels països del sud d’Àsia escolaritzades a Catalunya

Aquesta recerca aborda la interpretació de les relacions entre escolarització, immigració i gènere de forma complexa mitjançant la construcció d’una recerca visual narrativa i d’històries de vida amb el grup de noies/dones immigrades procedent dels països del sud d’Àsia que viuen i han estat escolaritzades –totalment o parcialment– a Catalunya. La investigació dóna visibilitat a les trajectòries d’èxit escolar de les noies/dones immigrades al seu pas per l’escola secundària, tot narrant: les seves expectatives i desitjos, els moments i canvis, les identitats i relacions, així com els aprenentatges assolits i les perspectives de futur. La recerca s’ha portat a terme a partir d’observar, entrevistar i conversar amb diversos grups de noies immigrades (principalment de la regió del Panjab de l’Índia i el Pakistan) en 4 centres educatius i 1 entitat, de l’àmbit de Barcelona i la seva àrea metropolitana. La investigació reconstrueix la trajectòria de 20 noies immigrades com a protagonistes. El treball de camp etnogràfic i la construcció de les històries visuals de vida culmina amb l’edició d’un documental audiovisual. De forma resumida, l’anàlisi de les dades realitzada a partir del treball de camp etnogràfic, de les entrevistes en profunditat i les converses en els cinc contextos presentats, s’organitza d’acord amb els següents eixos temàtics: 1. Migracions, espacialització i mobilitat en un context transnacional i local; 2. La construcció de les subjectivitats i del gènere de les adolescents/adultes immigrades; 3. Processos d’escolarització i formació a Catalunya de les noies/dones immigrades; i 4. Visibilitat, visualitat i representació en la recerca.

Testing the predictive adaptive response in a host-parasite system

1. Harsh environmental conditions experienced during development can reduce the performance of the same individuals in adulthood. However, the 'predictive adaptive response' hypothesis postulates that if individuals adapt their phenotype during development to the environments where they are likely to live in the future, individuals exposed to harsh conditions in early life perform better when encountering the same harsh conditions in adulthood compared to those never exposed to these conditions before. 2. Using the common vole (Microtus arvalis) as study organism, we tested how exposure to flea parasitism during the juvenile stage affects the physiology (haematocrit, resistance to oxidative stress, resting metabolism, spleen mass, and testosterone), morphology (body mass, testis mass) and motor performance (open field activity and swimming speed) of the same individuals when infested with fleas in adulthood. According to the 'predictive adaptive response' hypothesis, we predicted that voles parasitized at the adult stage would perform better if they had already been parasitized with fleas at the juvenile stage. 3. We found that voles exposed to fleas in adulthood had a higher metabolic rate if already exposed to fleas when juvenile, compared to voles free of fleas when juvenile and voles free of fleas in adulthood. Independently of juvenile parasitism, adult parasitism impaired adult haematocrit and motor performances. Independently of adult parasitism, juvenile parasitism slowed down crawling speed in adult female voles. 4. Our results suggest that juvenile parasitism has long-term effects that do not protect from the detrimental effects of adult parasitism. On the contrary, experiencing parasitism in early-life incurs additional costs upon adult parasitism measured in terms of higher energy expenditure, rather than inducing an adaptive shift in the developmental trajectory. 5. Hence, our study provides experimental evidence for long term costs of parasitism. We found no support for a predictive adaptive response in this host-parasite system.

The corrosion of career? Occupational trajectories of engineers and business economists in Switzerland

This doctoral thesis deals with the rise and potential fall of achievement career as an institutional biographical pattern. I start with the assumption that the achievement career, as a result of the spread of large-scale bureaucratic companies, the male-breadwinner family model, and meritocratic ideals, came to life in the first half of the twentieth century. During the so-called 30 glorieuses, it became even a normatively dominant and also politically significant male biographical pattern. But the structural changes that announced the end of the post-war golden age seemed also to threaten and-according to certain scholars-erode this type of occupational trajectory. In order to understand this dynamic I will try to reconstruct the achievement career in Switzerland empirically. I examine (1) the structural changes of the economic field from 1970 to 2000, (2) the transformations of the trajectories during this period, and (3) ways in which the concerned individuals interpret and react to these changes.

Barriers in health care to breast cancer: perception of women

Identifying the barriers in the access to health care to breast cancer perceived by women undergoing chemotherapy.Method: An exploratory descriptive study. The sample consisted of 58 women with breast cancer receiving chemotherapy and registered in the public oncology ambulatory of Aracaju-Sergipe. Data collection was carried out between October 2011 and March 2012 by semistructured interviews, and data were processed using the SPSS, version 17.Results: Among the interviewed women, 37 (63.8%) reported at least a barrier in the trajectory of care for breast cancer. The organizational and health services barriers were the most reported in the periods of investigation and treatment of breast cancer.Conclusion: In face of these findings, the barriers should be considered in public health policies and programs for the control of breast cancer in Sergipe.



Late diagnosis and vulnerabilities of the elderly living with HIV/AIDS

OBJECTIVE To identify vulnerabilities of elderly people with HIV/AIDS and the trajectory that they follow until reaching the diagnosis of the disease. METHOD Qualitative research conducted in specialized clinics in the state of São Paulo, from January to June 2011. Semi-structured interviews were conducted with 11 elderly people who were found to be infected with the virus at the age of 60 years or older. The interviews were analyzed using content analysis. RESULTS In this process four categories emerged, then analyzed with reference to the theoretical framework of vulnerability. CONCLUSION Late diagnosis of HIV infection or AIDS among the elderly happens in the secondary or tertiary service. Issues related to sexual life of the elderly are only questioned by health professionals after the diagnosis, also the time that condom use becomes absolute. It is believed that the investigation of the vulnerability of the elderly to HIV/AIDS allows for carrying out appropriate interventions for this population.

Parallel imaging with phase scrambling.

PURPOSE: Most existing methods for accelerated parallel imaging in MRI require additional data, which are used to derive information about the sensitivity profile of each radiofrequency (RF) channel. In this work, a method is presented to avoid the acquisition of separate coil calibration data for accelerated Cartesian trajectories. METHODS: Quadratic phase is imparted to the image to spread the signals in k-space (aka phase scrambling). By rewriting the Fourier transform as a convolution operation, a window can be introduced to the convolved chirp function, allowing a low-resolution image to be reconstructed from phase-scrambled data without prominent aliasing. This image (for each RF channel) can be used to derive coil sensitivities to drive existing parallel imaging techniques. As a proof of concept, the quadratic phase was applied by introducing an offset to the x(2) - y(2) shim and the data were reconstructed using adapted versions of the image space-based sensitivity encoding and GeneRalized Autocalibrating Partially Parallel Acquisitions algorithms. RESULTS: The method is demonstrated in a phantom (1 × 2, 1 × 3, and 2 × 2 acceleration) and in vivo (2 × 2 acceleration) using a 3D gradient echo acquisition. CONCLUSION: Phase scrambling can be used to perform parallel imaging acceleration without acquisition of separate coil calibration data, demonstrated here for a 3D-Cartesian trajectory. Further research is required to prove the applicability to other 2D and 3D sampling schemes. Magn Reson Med, 2014. © 2014 Wiley Periodicals, Inc.

Schubert i les seves composicions per a violí

Amb aquest projecte he volgut aproximar-me al repertori de cambra per violí i piano del compositor vienès Franz Schubert. Les tres obres escollides són poc habituals a les sales de concert, en part per la seva complexitat tècnica i interpretativa, i representen tres propostes ben contrastants en la seva trajectòria compositiva. Es tracte de la introspectiva Sonatina en La menor D. 385, l’eloqüent Rondó Brillant en Si menor D. 895 i la seva obra de maduresa, la gran Fantasia en Do Major D. 934. Gràcies a l’anàlisi musical i la recerca del seu context cultural i artístic, juntament amb la meva experiència en l’instrument, he guanyat una percepció i comprensió molt més profunda de les seves obres, creixent com a persona i intèrpret amb el procés.

Appartenances en fête: entre l'ordinaire et le spectaculaire

Résumé Alors que les pratiques religieuses régulières diminuent et que les groupes religieux majoritaires perdent des membres formellement enregistrés, une évènementisation de l'appartenance religieuse peut être observée depuis environ deux décennies. Dans un premier exemple, l'auteure montre que le réseau transnational de la confrérie soufie des Mourides resserre les liens entre adeptes dans un contexte migratoire qui tend à fragiliser les relations sociales. La confrérie y fait face à travers une spectacularisation de la pratique religieuse, occupant l'espace public à Harlem ou, dans une moindre mesure, à Paris. Le second exemple traite du pèlerinage aux Saintes et Saints d'Afrique dans la ville valaisanne de Saint Maurice. Ce dernier fut inventé par l'Église catholique suisse afin d'attirer des migrants africains, mais aussi afin de redynamiser une pratique religieuse ordinaire en perte de vitesse. L'évènement a lieu en même temps que le pèlerinage de Namugongo en Ouganda, réunissant plus d'un demi-million de personnes. Les communautés évènementielles ainsi créées sont-elles durables ou plutôt liquides ? Abstract While regular religious practice is decreasing and the major religious groups are losing formally registered members, a 'spectacularization' of religious belonging can be observed over the last two decades. The author presents two examples to support this argument. In the first, the transnational network of the Murids, a Sufi brotherhood, has tried to reinforce the relations between its members, which become fragile during migration. The brotherhood occupies a public space in Harlem, and, to a lesser extent, in Paris, in a spectacularization of religious belonging, in order to remain attractive to migrants. The second example deals with the pilgrimage dedicated to African Saints in the Swiss town of Saint Maurice. This event was invented by the missionary service of the Swiss Catholic Church in order to attract African migrants, but also in order to make ordinary religious practice more appealing. The event takes place at the same time as the Ugandan pilgrimage of Namugongo, which assembles more than half a million people. However, are these 'event communities' sustainable or ephemeral?

Aromatherapy and nursing: historical and theoretical conception

Abstract Aromatherapy is a Practical or Complementary Health Therapy that uses volatile concentrates extracted from plants called essential oils, in order to improve physical, mental and emotional well-being. Aromatherapy has been practiced historically and worldwide by nurses and, as in Brazil is supported by the Federal Nursing Council, it is relevant to discuss this practice in the context of Nursing through Theories of Nursing. This study of theoretical reflection, exploratory and descriptive, aims to discuss the pharmacognosy of essential oils, the historical trajectory of Aromatherapy in Nursing and the conceptions to support Aromatherapy in light of eight Nursing Theorists (Florence Nightingale, Myra Levine, Hildegard Peplau, Martha Rogers, Callista Roy, Wanda Horta, Jean Watson and Katharine Kolcaba), contributing to its inclusion as a nursing care practice.

An attempt to refine rockfall hazard zoning based on the kinetic energy, frequency and fragmentation degree

Rockfall hazard zoning is usually achieved using a qualitative estimate of hazard, and not an absolute scale. In Switzerland, danger maps, which correspond to a hazard zoning depending on the intensity of the considered phenomenon (e.g. kinetic energy for rockfalls), are replacing hazard maps. Basically, the danger grows with the mean frequency and with the intensity of the rockfall. This principle based on intensity thresholds may also be applied to other intensity threshold values than those used in Switzerland for rockfall hazard zoning method, i.e. danger mapping. In this paper, we explore the effect of slope geometry and rockfall frequency on the rockfall hazard zoning. First, the transition from 2D zoning to 3D zoning based on rockfall trajectory simulation is examined; then, its dependency on slope geometry is emphasized. The spatial extent of hazard zones is examined, showing that limits may vary widely depending on the rockfall frequency. This approach is especially dedicated to highly populated regions, because the hazard zoning has to be very fine in order to delineate the greatest possible territory containing acceptable risks.

Impactos Decorrentes da Expansão da Cidade de Assomada, Município de Santa Catarina – Cabo Verde

Esta dissertação tem por finalidade evidenciar os “Impactos Decorrentes da Expansão da Cidade de Assomada”. Propõe-se ainda, analisar a relação urbanorural no município de Santa Catarina, Cabo Verde. Essa análise incidiu sobre os dados da sua ocupação, que remonta à 2ª metade do século XIX, no decurso da crise e decadência da primeira cidade de Cabo Verde (Ribeira Grande, atual Cidade- Velha) e às conjunturas regionais e nacionais que condicionaram sua trajetória, bem como, os principais agentes intervenientes na transformação do espaço urbano de Assomada (Estado, proprietários de terra e comerciantes), sobretudo, no período que decorre de 1961 a 2003. A pesquisa empreendida demonstra que a “ruralidade” é um dos aspectos fundamentais de Santa Catarina, abrangendo 21,3% da população rural do território nacional e 37,9% da ilha de Santiago. Do ponto de vista urbanístico, o mapeamento da evolução da cidade de Assomada, referente à área ocupada pelas edificações nesse lapso de tempo, permite-nos perceber um crescimento bastante acelerado desse espaço urbano, sobretudo, a partir dos anos 90. Dois aspectos importantes se encontram na base dessa transformação: a Independência Nacional ocorrida em 1975 e a Emigração. Com a Independência, o país passou a beneficiar de amplos programas de cooperação internacional o que veio a reforçar a sua importância econômica e política, visualizada através de projetos industrializantes, infra-estruturas e equipamentos de diversas naturezas. Esses investimentos foram por sua vez reforçados por aportes dos emigrantes, que passaram a ser um dos parceiros fundamentais no desenvolvimento de Santa Catarina, através de iniciativas privadas e empresariais, como a construção de residências e constituição de empresas. A análise do indicador uso e ocupação do solo urbano permitiu-nos identificar alguns impactos ambientais causados, sobretudo, pela falta de instrumentos de gestão urbanística, ausência de cadastro municipal e uma deficiente fiscalização dos órgãos administrativos.

Colonic movements in healthy subjects as monitored by a Magnet Tracking System.

The Magnet Tracking System (MTS) is a minimally-invasive technique of continuous evaluation of gastrointestinal motility. In this study, MTS was used to analyse colonic propulsive dynamics and compare the transit of a magnetic pill with that of standard radio-opaque markers. MTS monitors the progress in real time of a magnetic pill through the gut. Ten men and 10 women with regular daily bowel movements swallowed this pill and 10 radio-opaque markers at 8 pm. Five hours of recordings were conducted during 2 following mornings. Origin, direction, amplitude and velocity of movements were analysed relative to space-time plots of the pill trajectory. Abdominal radiographs were taken to compare the progress of both pill and markers. The magnetic pill lay idle for 90% of its sojourn in the colon; its total retrograde displacement accounted for only 20% of its overall movement. Analysis of these movements showed a bimodal distribution of velocities: around 1.5 and 50 cm min(-1), the latter being responsible for 2/3 of distance traversed. There were more movements overall and more mass movements in males. Net hourly forward progress was greater in the left than right colon, and greater in males. The position of the magnetic pill correlated well with the advancement of markers. MTS showed patterns and propulsion dynamics of colonic segments with as yet unmet precision. Detailed analysis of slow and fast patterns of colonic progress makes it possible to specify the motility of colonic segments, and any variability in gender. Such analysis opens up promising avenues in studies of motility disorders.

Comparative morphology of the mandibles of female polistine social wasps (Hymenoptera, Vespidae, Polistinae)

Comparative morphology of the mandibles of female polistine social wasps (Hymenoptera, Vespidae, Polistinae). Diversity of mandibular forms in female polistines is explored and compared among 116 species of all polistine genera. Inferences about function are made and discussed based on observed form differences. Mandible length and width measurements are analyzed for a subset of polistine species plus two vespines and two eumenines. A variable expressing the ratio between these variables is also considered in morphometric analyses. The following mechanical interactions among mandible structural elements are highlighted: opposition and crossing of mandibles' apical teeth at the middle of the closing trajectory; shearing action of the apical teeth against mesial denticles of the opposite mandible; shearing action of the mandible anterior margin against the ventral margin of the clypeus. In the genera Agelaia and Angiopolybia, exceptionally developed mesial mandibular structures may be related to necrophagy. In some epiponine genera, poorly developed mesial denticles and strong torsion of mandibles may be partially related to use of short wood fibers in nest construction as advanced by Sarmiento (2004). The considerable morphological variation found across the subfamily Polistinae is certain to be important in taxonomic and phylogenetic studies at the genus and species levels.

Facteurs de risque fracturaire, nouveaux traitements: comment evolue la prise en charge de l'ostéoporose de la personne agée [Fracture risk, new treatments: how does the management of the osteoporosis of elderly change?]

Osteoporosis of elderly is a growing medical, economic and health-care problem. It is due to the increase of the life expectancy and the number of osteoporotic fractures. With the new Swiss-specific tool FRAX and the development of inpatients fracture trajectory, we can better identify patients with high risk of fracture. An appropriate treatment can be proposed more quickly. The follow-up of bone markers increases the treatment efficiency. With a better identification, treatment and follow-up of osteoporosis of elderly patients, we can ameliorate the patient's quality of life and decrease the number of osteoporotic fractures with a good cost-effectiveness ratio.

Lung microbiota promotes tolerance to allergens in neonates via PD-L1.

Epidemiological data point toward a critical period in early life during which environmental cues can set an individual on a trajectory toward respiratory health or disease. The neonatal immune system matures during this period, although little is known about the signals that lead to its maturation. Here we report that the formation of the lung microbiota is a key parameter in this process. Immediately following birth, neonatal mice were prone to develop exaggerated airway eosinophilia, release type 2 helper T cell cytokines and exhibit airway hyper-responsiveness following exposure to house dust mite allergens, even though their lungs harbored high numbers of natural CD4(+)Foxp3(+)CD25(+)Helios(+) regulatory T (Treg) cells. During the first 2 weeks after birth, the bacterial load in the lungs increased, and representation of the bacterial phyla shifts from a predominance of Gammaproteobacteria and Firmicutes towards Bacteroidetes. The changes in the microbiota were associated with decreased aeroallergen responsiveness and the emergence of a Helios(-) Treg cell subset that required interaction with programmed death ligand 1 (PD-L1) for development. Absence of microbial colonization(10) or blockade of PD-L1 during the first 2 weeks postpartum maintained exaggerated responsiveness to allergens through to adulthood. Adoptive transfer of Treg cells from adult mice to neonates before aeroallergen exposure ameliorated disease. Thus, formation of the airway microbiota induces regulatory cells early in life, which, when dysregulated, can lead to sustained susceptibility to allergic airway inflammation in adulthood.
