El proceso de doble carrera en Brasil: revelando tipologías

Un fenómeno que aparece estrechamente relacionado con los cambios en el contexto social, económico y cultural, y que sigue creciendo a lo largo de los años, ha atraído la atención de investigadores en el sentido de desarrollar estudios que incluyan tanto al individuo como el campo organizacional. Conocido como familias de doble carrera, este fenómeno pone de relieve un movimiento conjunto de marido y mujer (pareja) en el ámbito de la familia y el desarrollo de la carrera profesional de ambos. Con el fin de saber cómo se establecen estas relaciones, en este estudio se investigan los factores que constituyen el fenómeno de doble carrera en el contexto brasileño. La encuesta ha contado con 340 participantes, todos ex alumnos de una universidad pública que deberían estar casados o hacer vida marital. Los resultados permiten identificar, por medio de la estadística descriptiva, el perfil de las parejas con dos carreras en el ámbito brasileño y comprobar qué tipos de doble carrera existen en el país. Se han obtenido cinco tipos de doble carrera: familista coordinada, familista convencional, centrada en la carrera coordinada, centrada en la carrera convencional y acróbata.Um fenômeno que surge estreitamente relacionado às mudanças nos âmbitos social, econômico e cultural, e que cresce à medida que os anos caminham, vem despertando a atenção de pesquisadores para o desenvolvimento de estudos que envolvem tanto o campo individual quanto o organizacional.

Named as "dual career family", this phenomenon emphasizes a joint move from a husband and wife (a couple) in the family sphere and in the development of both careers. Thus, in order to know how these relationships are being established, this study set out to investigate what are the determining factors that compose the dual career phenomenon in the Brazilian context. The research involved 340 participants, all former students of a public university, married or living in a marital status. The results allowed to feature, through descriptive statistics, the profile of dual career couples in the Brazilian scene and check what are the types of dual career in the country. We obtained five types of dual career: coordinated familistic, conventional familistic, coordinated careerist, conventional careerist and acrobat

Marginal resection and adjuvant strontium plesiotherapy in the management of feline eyelid malignant peripheral nerve sheath tumours: two cases

Case series summary Two cats with a marginally resected eyelid malignant peripheral nerve sheath tumour were treated with adjuvant strontium plesiotherapy a few weeks after surgery. The dose applied in both cases was 200 Gy to the surface, in five fractions, on a Monday–Wednesday–Friday basis. The treatment aimed to achieve a clinical margin of approximately 1 cm around the surgical scar and multiple application fields were required to cover such an area. Local recurrence was not seen in either case after 1330 and 645 days, respectively. Relevance and novel information The majority of periocular malignant peripheral nerve sheath tumours reported in the literature recur after surgery. In the two cases described in this report the combination of surgery and adjuvant plesiotherapy has been able to provide good local control with minimal toxicity. This multimodal approach could be considered as an alternative to aggressive surgery such as enucleation or exenteration

Gamma-ray bursts as cool synchrotron sources

Gamma-ray bursts are the most energetic electromagnetic sources in the Universe. Their prompt gamma-ray radiation corresponds to an energy release of 1E42-1E47J. Fifty years after their discovery and several dedicated space-based instruments, the physical origin of this emission is still unknown. Synchrotron emission has been one of the early contenders but was criticized because spectral fits of empirical models (such as a smoothly-connected broken power law or a cut-off power law) suggest too hard a slope of the low-energy power law, violating the so-called synchrotron line-of-death. We perform time-resolved gamma-ray spectroscopy of single-peaked GRBs as measured with Fermi/GBM. We demonstrate that idealized synchrotron emission, when properly incorporating time-dependent cooling of the electrons, is capable of fitting ~95% of all these GBM spectra. The comparison with spectral fit results based on previous empirical models demonstrates that the past exclusion of synchrotron radiation as an emission mechanism derived via the line-of-death was misleading. Our analysis probes the physics of these ultra-relativistic outflows and the related microphysical processes, and for the first time provides estimates of magnetic field strength and Lorentz factors of the emitting region directly from spectral fits. Our modeling of the Fermi/GBM observations provides evidence that GRBs are produced by moderately magnetized jets in which relativistic mini-jets emit optically-thin synchrotron radiation at large emission radii.Comment: submitte

Condition monitoring indicators for pitting detection in planetary gear units

In industrial field, there is an increasing demand for monitoring systems enabling predictive maintenance programs. In this context, the present work concerns the monitoring of distributed wear (pitting) in planetary gearboxes. For this purpose, some metrics of the synchronous average of the vibration signal, based on the statistical moment of the fourth order, are present in literature; in this paper, a new indicator is proposed, namely NA4mod. The effectiveness of this metric in identifying the early stage of pitting has been evaluated by conducting an accelerated life test of about 700 hours on a test bench using a back-to-back configuration. The paper introduces the proposed metric, describes the test, presents and dis-cusses the results. Metric NA4mod exhibits satisfactory capability to detect pitting with better reliability than other metrics in literature. In addition, the metric is shown to be sensitive to both early stage damage and pitting severity in the final stage. Results are verified by means of wavelet-transform analysis

Cellular Proliferation in the Prognosis of Intermediate Grade Mast Cell Tumour in Dogs

This was a retrospective study including ninety samples of dogs with a histological diagnosis of intermediate grade cutaneous mast cell tumour (MCT). The objectives of the study were to validate Minichromosome Maintenance Protein 7 (MCM7) as a prognostic marker in MCTs and to compare the ability of mitotic index (MI), Ki67 and MCM7 to predict outcome. The median survival for the entire population was not reached at 2099 days. The mean survival time was 1708 days. Seventy-two cases were censored after a median follow up of 1136 days and eighteen dogs died for causes related to the MCT after a median of 116 days. For each sample MI, Ki67 and MCM7 were determined. The Receiver Operating Characteristic (ROC) curve was obtained for each prognostic marker to evaluate the performance of the test, expressed as area under the curve, and whether the published threshold value was adequate. Kaplan-Meier and corresponding logrank test for MI, Ki67 and MCM7 as binary variables was highly significant (P 0.18 (Hazard Ration [HR] 14.7; P 5 (HR 13.9; P 0.018 (HR 8.9; P<0.001). Concluding, the present study confirmed that MCM7 is an excellent prognostic marker in cutaneous MCTs being able to divide Patnaik intermediate grade tumours in two categories with different prognosis. Ki67 was equally good confirming its value as a prognostic marker in intermediate grade MCTs. The mitotic index was extremely specific, but lacked of sensitivity. Interestingly, mitotic index, Ki67 and MCM7 were independent from each other suggesting that their combination would improve their individual prognostic value

Orientador: Roberta Rafaela Sotero CostaMonografia (especialização) - Universidade Federal do Paraná, Especialização em Mídias Integradas na EducaçãoInclui referênciasResumo: Este trabalho envolve o uso de mídias na educação de jovens e adultos (EJA) e tem a finalidade de apresentar algumas considerações importantes sobre a inclusão digital e o uso das Tecnologias de Informação e Comunicação (TIC’s) na escola e no processo de ensino e aprendizagem. A pesquisa de campo proporcionou levantar dados importantes sobre o conhecimento que os professores e alunos de EJA têm sobre a inclusão digital e como a mesma vem se processando na escola e no cotidiano. O desconhecimento desses termos ainda é grande no espaço escolar, professores e alunos do ensino regular não avançaram satisfatoriamente no sentido de usar as ferramentas como apoio para melhor a pesquisa e consequentemente o ensino em sala de aula. Com professores e alunos de EJA as dificuldades são ainda maiores, existem outros entraves que dificultam o progresso dos educandos em outras instâncias da aprendizagem. Os alunos jovens e adultos necessitam estar incluídos no mundo digital, são exigências da sociedade e do trabalho, portanto as propostas de inclusão digital e das TIC’s, são prioritárias para inserir esses indivíduos no mundo do trabalh
