Este artículo explora las fuentes de incertidumbre en la experiencia contemporánea del amor y las estrategias que los jóvenes españoles ponen en práctica para afrontarla. Para ello, se utiliza el material empírico obtenido a través de la realización de 31 entrevistas en profundidad a adultos jóvenes entre 25 y 35 años de edad, residentes en Madrid. Su análisis ha permitido identificar una serie de estrategias que apuntan hacia la extensión de cierta “normatividad de la cautela” en la experiencia de los vínculos amorosos: a) La “disciplina emocional” para controlar la imagen que se otorga de los propios sentimientos, b) la concatenación de emparejamientos, c) la priorización del propio “yo” en las expectativas y d) la búsqueda de fórmulas alternativas al modelo de pareja monógama tradicional. Se analiza, además, cómo cada una de estas estrategias se hace plausible en función de determinados contextos y posiciones de clase y género.

En el presente trabajo indagaremos sobre la reconfiguración de las dinámicas institucionales en dos cárceles de la provincia de Santa Fe, Argentina, tras la inserción del dispositivo religiosoevangélico- pentecostal. Los casos serán las penitenciarías n° 3 —mediana seguridad— y n° 11 — máxima seguridad—, y nos interrogaremos sobre las relaciones de reciprocidad que el dispositivo religioso configura en el encierro, en cómo dichas relaciones definen nuevas estrategias de gobierno por parte del servicio penitenciario y de qué manera se rediseñan las relaciones de poder en el dispositivo carcelario. Abordaje comparativo que responde a la hipótesis de que el dispositivo religioso-evangélicopentecostal construye matrices comunes de ordenamiento social, funcionamiento y reciprocidades en el encierro pero, al mismo tiempo, consolida su funcionamiento a raíz de una identificación precisa de las necesidades y oportunidades de los sujetos según atraviesen situaciones de ingreso o egreso carcelario.

This thesis nalyzes the wayfinding in Landscape Museum of Contemporary Art (MPAC), based on the Institute of Contemporary Art CACI, Minas Gerais, Brazil and the Museum of Contemporary Art of the Serralves Foundation, Porto, Portugal. The study focuses on the interrelationship of the public/visitors with the landscape, architecture and contemporary art museums in these, in order to understand visual perception and apprehension of such an environment for their users. For both were confronted documentation (visual and written) and people talk. The main hypothesis put forward is that the audience/visitor MPAC appreciates the interrelationship between the natural environment (park/garden) and built environment (the works of contemporary art and the galleries), giving equal value to both. To complement this, a second hypothesis is that during the visit to MPACS, visitors define their paths spontaneously, but strongly influenced by existing visual indicators (maps, signage and striking landscape elements), which facilitate the readability of space, which also contribute to the offered services and the experiences of similar institutions. The analytical basis of the research used the concepts of legibility (LYNCH, 2009), wayfinding (GIBSON, 2009; ARTHUR, PASSINI, 2002; WEISMAN, 1982), Experiential Cotinnum (TUAN, 1985), Space Bound (CRUZ PINTO, 2007) and habitus (BOURDIEU, 1992). Methodologically was used qualitative research (DEMO 2000) by means of a case study (YIN, 2005; STAKE, 1999) and participant observation (WHYTE, 2005). In the two institutions interviews with researchers and curators, behavior observation and questionnaires from employees, trainees, monitors and the public/visitor of the two museums were performed. Although partially referende the initial hypothesis, the research showed that the public/visitor value appears more natural environments, they experience a greater intensity and in addition to the factors listed in the second case, your perception and definition of paths suffer significant influence of emotional relations established with space. Generally the audience/visitor adapts easily to different demands of contemporary art exhibition in the two museums and the built environment (park/garden and museum) interferes with your reading path during the visit, perceived by the public/visitor condition as a factor that favors the enjoyment of works on different mounts (wayfinding), though often become a factor that hinders the legibility of the building and its built environment

Esta investigação, de natureza qualitativa, visou conhecer as concepções e práticas de professores dos anos iniciais sobre o ensino de ciências e promover reflexões sobre tal ensino. O trabalho teve como base o Processo de Reflexão Orientada, uma estratégia para o desenvolvimento profissional a partir do enfoque de questões da prática docente. As questões de investigação foram: Como professores dos anos iniciais concebem, refletem, planejam e realizam o ensino de Ciências? Como refletem e realizam o ensino de Ciências a partir de um Processo de Reflexão Orientada? E, como a partir de um Processo de Reflexão Orientada para professores dos anos iniciais do Ensino Fundamental avaliam o seu próprio desenvolvimento profissional? Os dados foram obtidos a partir de questionários, entrevistas, planejamentos escritos e de vídeogravações dos encontros e de aulas ministradas. Sequências de ensino foram planejadas e discutidas, novas reflexões foram realizadas e reelaborações foram propostas. As aulas desenvolvidas evidenciaram um progresso de Lívia com relação à participação dos alunos, com a proposição de uma situação-problema, da consideração das ideias prévias dos alunos, embora apresentasse ainda dificuldades em promover uma discussão orientada, que pudesse favorecer a argumentação dos alunos e a compreensão do fenômeno. Já, nas aulas de Roberta observaram-se atividades que privilegiaram a participação dos alunos. O processo de reflexão orientada mostrou ser uma estratégia importante para o desenvolvimento profissional dessas professoras, possibilitando reflexões significativas sobre a própria prática, bem como a tomada de consciência de uma nova sistematização das ações docentes.

This study evaluated the antifungal susceptibility profile and the production of potential virulence attributes in a clinical strain of Candida nivariensis for the first time in Brazil, as identified by sequencing the internal transcribed spacer (ITS)1-5.8S-ITS2 region and D1/D2 domains of the 28S of the rDNA. For comparative purposes, tests were also performed with reference strains. All strains presented low planktonic minimal inhibitory concentrations (PMICs) to amphotericin B (AMB), caspofungin (CAS), and voriconazole. However, our strain showed elevated planktonic MICs to posaconazole (POS) and itraconazole, in addition to fluconazole resistance. Adherence to inert surfaces was conducted onto glass and polystyrene. The biofilm formation and antifungal susceptibility on biofilmgrowing cells were evaluated by crystal violet staining and a XTT reduction assay. All fungal strains were able to bind both tested surfaces and form biofilm, with a binding preference to polystyrene (p < 0.001). AMB promoted significant reductions (≈50%) in biofilm production by our C. nivariensis strain using both methodologies. This reduction was also observed for CAS and POS, but only in the XTT assay. All strains were excellent protease producers and moderate phytase producers, but lipases were not detected. This study reinforces the pathogenic potential of C. nivariensis and its possible resistance profile to the azolic drugs generally used for candidiasis management.

Este trabajo examina la evolución de los roles de género en diferentes regiones del mundo. Usando datos para 12 países de los tres últimos módulos del ISSP “Family and Changing Gender Roles” (1994, 2002 and 2012), se compara la evolución de los roles de género en lo que se refiere a la maternidad y su relación con la extensión de la incorporación laboral de las mujeres en todo el mundo: cuatro países europeos occidentales, representantes de diferentes regímenes de bienestar (Alemania, Reino Unido, Noruega y España), Estados Unidos, dos países de Europa del Este (Polonia y República Checa) y Rusia, dos países latinoamericanos (Chile y México) y dos asiáticos (Japón y Taiwán). Los datos muestran que el cambio en la familia (medido tanto en términos de actitudes como de prácticas sociales) se está expandiendo desde los contextos occidentales hacia otras regiones del mundo, aunque el ritmo de este cambio varía de un país a otro, dependiendo de factores políticos, culturales y económicos.

Aim: To investigate the relation between uncooperative behavior and salivary cortisol level in children who underwent preventive dental care. Methods: The sample was composed by 10 children of both sexes aged 40 to 52 months, presenting uncooperative behavior during dental preventive treatments. The saliva collection was performed using a cotton wheel and an Eppendorf tube (Sarstedt Salivete®) in 3 different moments: a) at home, on a day without dental treatment and at the same time on the day of the sessions treatment; b) 30 min after the end of the session, when there was manifestation of uncooperative behavior; c) 30 min after the end of the session, when there was a cooperative behavior of the child. A sample of saliva was centrifuged for 5 minutes at 2400 rpm, 1 of mL of saliva was pipetted in an Eppendorf tube and stored in a freezer at -20 ° C. For the determination of the levels of salivary cortisol was used an Active® kit for cortisol enzyme immunoassay (EIA) DSL-10-67100, composed of specific rabbit antibody anti-cortisol. Data were analyzed statistically for the uncooperative behavior issued in the beginning and at the end of sessions, using the paired t test (p<0.05) and for cortisol levels in saliva samples at home, after the beginning and at the end of sessions, using repeated-measures ANOVA and Tukey’s test (p<0.05). Results: During expression of uncooperative behavior in preventive dental care sessions the salivary cortisol level was significantly higher (0.65 ± 0.25 μg/dL) compared with expression of collaborative behavior (0.24 ± 0.10 μg/dL). Conclusions: It is possible to conclude that, even under preventive intervention, the stress must be controlled in order to reduce dental anxiety and fear.
