Somewhere near reality: artistic portrayal of violence in post WWII British realistic drama

ABSTRACT - I will explore and present the portrayal of violence in some British plays that were staged between 1951 and 1965, in order to discuss the role, impact and aim of its representation. Thus, I will consider John Whiting’s Saint’s Day (1951), Ann Jelicoe’s The Sport of my Mad Mother (1956), Arnold Wesker (Chicken Soup with Barley (1958), Harold Pinter’s Birthday Party (1958), David Rudkin’s Afore Night Come (1962) and Edward Bond’s Saved (1965). My aim is to discuss the way how theatre in the post WWII changed the traditional ways of representing violence. On one hand, violence and reality became more and more familiar and domestic, permitting a representation of multiple and non-agonic violence; and, on the other hand, the violence that was depicted often changed the way one perceived reality itself, being part of a socially engaged artistic attitude.

POST-PROCESSING TECHNIQUES SUITABILITY FOR MESOLEVEL FREE BOUNDARY FLOWS

Reliable flow simulation software is inevitable to determine an optimal injection strategy in Liquid Composite Molding processes. Several methodologies can be implemented into standard software in order to reduce CPU time. Post-processing techniques might be one of them. Post-processing a finite element solution is a well-known procedure, which consists in a recalculation of the originally obtained quantities such that the rate of convergence increases without the need for expensive remeshing techniques. Post-processing is especially effective in problems where better accuracy is required for derivatives of nodal variables in regions where Dirichlet essential boundary condition is imposed strongly. In previous works influence of smoothness of non-homogeneous Dirichlet condition, imposed on smooth front was examined. However, usually quite a non-smooth boundary is obtained at each time step of the infiltration process due to discretization. Then direct application of post-processing techniques does not improve final results as expected. The new contribution of this paper lies in improvement of the standard methodology. Improved results clearly show that the recalculated flow front is closer to the ”exact” one, is smoother that the previous one and it improves local disturbances of the “exact” solution.

Post-processing Techniques in Free Boundary Flows during Liquid Composite Moulding Processes

Post-processing a finite element solution is a well-known technique, which consists in a recalculation of the originally obtained quantities such that the rate of convergence increases without the need for expensive remeshing techniques. Postprocessing is especially effective in problems where better accuracy is required for derivatives of nodal variables in regions where Dirichlet essential boundary condition is imposed strongly. Consequently such an approach can be exceptionally good in modelling of resin infiltration under quasi steady-state assumption by remeshing techniques and with explicit time integration, because only the free-front normal velocities are necessary to advance the resin front to the next position. The new contribution is the post-processing analysis and implementation of the freeboundary velocities of mesolevel infiltration analysis. Such implementation ensures better accuracy on even coarser meshes, which in consequence reduces the computational time also by the possibility of employing larger time steps.

Formación de profesores post Bolonia: los desafíos de un proceso en dos etapas

En los últimos años, las políticas de formación de profesores se han convertido en un foco de interés para gobernantes, investigadores y profesionales de la educación. En Portugal, como en otros países europeos, la reestructuración de la formación de profesores estuvo marcada por las políticas, directrices y tendencias de la Comisión Europea, adecuándolas a las especificidades propias de la cultura e historia nacionales. Actualmente, la formación de profesores para los primeros años (0-12) se realiza en instituciones de enseñanza superior, bajo una estructura de dos etapas, constituida por el primer ciclo (licenciatura en Educación Básica) y el segundo ciclo (maestros en educación de infancia y/o ciclo de Enseñanza Básica), con una duración de 4,5 a 5 años. Esta organización en dos etapas ha traído nuevos desafíos a la coherencia y consistencia de los cursos de formación, sobre todo, por lo que respecta a la articulación de la formación académica con la formación práctica. Los problemas generados se vuelven especialmente relevantes en el 6º semestre de la licenciatura en Educación Básica, periodo de transición entre la conclusión de una etapa y el inicio de otra. En este artículo, relatamos el recorrido realizado en la organización de la formación en Educación Básica en una escuela superior de educación en Portugal. El proyecto duró 4 años e incidió en la orientación, organización y procesos de apoyo a la iniciación a la práctica profesional en el 6º semestre del curso. En este proceso, la participación e implicación de los estudiantes, a través de la evaluación de la formación, fue el rasgo fundamental y distintivo.

Clinical and endoscopic findings in the mucosae of the upper respiratory and digestive tracts in post-treatment follow-up of paracoccidioidomycosis patients

Systematic examination of the upper respiratory and digestive tracts (URDT) was performed in a group of 80 paracoccidioidomycosis (PCM) patients submitted to post-treatment follow-up ranging from 8 months to 17 years. Mucosae of the URDT had been involved prior to specific treatment in 74 patients, distributed as follows: oropharynx, 50 (41 alone, 7 in association with the larynx, and 2 with the nasal mucosa); larynx, 30 (23 alone and 7 in association); and nasal mucosa, 3(1 alone and 2 in association). Inactive lesions were observed in all the 50 patients with lesions of the oropharynx, 3 of whom with deforming scars (1 with retraction of the tongue and 2 with narrowing of the oral orifice). One case presented a destructive lesion, with perfuration of the palate. Of the other 46 cases, examination showed nacreous white striated scars which were nearly imperceptible in some cases and in others displayed partial retraction of anatomical structures without any alteration of their features. Patients presented a high rate of missing teeth. In 3 patients with involvement of the nasal mucosa, none of whom presented active PCM lesions, 2 still had nasal voices. In 30 patients with lesions of the larynx, 1 suffered a relapse of PCM and 2 developed epidermoid carcinoma. Of the other 27 cases, none of whom had active PCM lesions, 15 presented dysphonia, 3 were tracheotomized, and 9 were asymptomatic.

Repercussões crónicas nas vias aéreas da hiperóxia neonatal : modelo experimental

RESUMO: O objectivo deste trabalho foi avaliar se a exposição crónica neonatal à hiperóxia mo-derada induz alterações funcionais e estruturais persistentes nas vias aéreas. Desenvolveu-se um modelo animal, no rato, a partir do qual se retiraram implicações para a compreensão das repercussões crónicas da hiperóxia neonatal sobre as vias aéreas de displasia broncopulmonar (DBP), em duas fases distintas: imediatamente após a exposi-ção neonatal a 50%O2 (grupo 50%O2) e após três semanas de recuperação em ar ambiente (grupo 50%O2+Ar).Compararam-se os resultados da resposta do músculo liso de traqueia (MLT) à esti-mulação in vitro com metacolina e salbutamol e avaliaram-se as alterações quantitativas da área de MLT, bem como as alterações qualitativas da estrutura da traqueia. Demonstrou-se que a exposição a 50% de oxigénio não tinha repercussões imediatas sobre a resposta in vitro do MLT à estimulação colinérgica, mas que induzia um aumento do relaxamento em resposta ao salbutamol. A contractilidade do MLT em resposta à estimula-ção com metacolina no grupo 50%O2+Ar foi significativamente superior à do grupo de con-trolo da mesma idade e também superior à observada no grupo 50%O2, enquanto que a resposta ao salbutamol se voltou a aproximar dos valores de controlo após a recuperação em normóxia. Não se observaram diferenças estatisticamente significativas na área de MLT entre os grupos experimental e de controlo, o que se deve provavelmente ao número reduzido de amostras avaliadas e à variabilidade deste parâmetro no grupo de controlo; contudo, verifi-cou-se um aumento médio de 15% imediatamente após a exposição à hiperóxia que persis-tiu após o período de recuperação.As alterações qualitativas sobre a arquitectura da traqueia, avaliadas por microscopia óptica, revelaram no grupo 50%O2 aumentos da espessura da matriz extracelular e da den-sidade de mastócitos desgranulados na submucosa e adventícia vizinhas do MLT, sem outras alterações relativamente ao grupo de controlo com 15 dias. As alterações da matriz extrace-lular foram reversíveis após a recuperação em ar ambiente. A densidade de mastócitos per-maneceu superior à do grupo de controlo de 36 dias de idade, apresentando-se em maior contiguidade com o MLT relativamente ao grupo 50%O2. Em síntese, demonstrou-se que a hiperóxia neonatal crónica em níveis moderados in-duz alterações da resposta contráctil do MLT e da estrutura da traqueia que podem ter ex-pressão funcional após a exposição ter cessado. Assim, o contributo original do presente trabalho foi o desenvolvimento de um modelo animal que permite avaliar os mecanismos pelos quais a hiperóxia é capaz de induzir, isoladamente, alterações crónicas da contracti-lidade, do relaxamento do ML e da estrutura das vias aéreas que podem ser responsáveis pela HRB persistente em doentes sujeitos a oxigenioterapia neonatal.-------------ABSTRACT: The aim of this work was to evaluate whether chronic neonatal exposure to hyperoxia in-duces persistent structural and functional airway changes. An animal model was developed, using neonatal rats, in order to understand the chronic effects of neonatal hyperoxia on the airways, in bronchopulmonary dysplasia, in two distinct phases: immediately after neonatal exposure to 50%O2 (50%O2 group) and after three weeks of recovery at ambient air (50%O2+Ar group).The results from the tracheal smooth muscle (TSM) response to in vitro stimulation with metacholine and salbutamol were compared and quantitative changes in TSM area, as well as qualitative changes in tracheal structure were evaluated. It was demonstrated that while exposure to 50% oxygen had no immediate effects on in vitro TSM response to cholinergic stimulation, it induced an increase in relaxation as a result of salbutamol administration. TSM contractility as a result of methacholine administration in the 50%O2 + Ar group was significantly higher than that of the same-age control group, and also higher than the one observed in the 50%O2 group, whereas the response to salbutamol admini-stration was once again closer to the control values after recovery in normoxia. There were no statistically significant differences in the TSM area between the experi-mental and control groups, which is most likely due to the reduced number of samples evalu-ated and to the variability of this parameter in the control group. However, there was an aver-age increase of 15% immediately after exposure to hyperoxia, which persisted after the recov-ery period. Qualitative changes in tracheal architecture, evaluated by optic microscopy, revealed that the 50%O2 group suffered an increase in the thickness of the extracellular matrix and degranu-lated mast cell density in the submucosa and adventitia adjacent to the TSM, without further changes when compared with the control group at 15 days of age. The changes in extracellular matrix were reversible after recovery in ambient air. Mast cell density remained higher than that of the control group at 36 days of age, and more contiguous to TSM than the 50%O2 group. In conclusion, it has been demonstrated that moderate levels of chronic neonatal hyperoxia in-duce changes in TSM contractile response and tracheal structure, which may be functionally ex-pressed after discontinuation of exposure. Therefore, the original contribution of the present work was the development of an animal model which allows the evaluation of the mechanisms through which hyperoxia alone can induce chronic changes in contractility and relaxation of SM and also in airway structure that can be responsible for the persistent airway hyperrespon-siveness found in patients who were submited to neonatal oxygen therapy.

Designing a technology assessment post-graduation programme: experiences, limits and needs

The post-graduation in the field of Technology Assessment (TA) is recent and that are several and different ways to be organised. Most experiences are related with the Masters diplom level (2nd cycle of graduation in high education). Just one in PhD level is explicit in the field of TA, and some other PhD courses include also TA topics in their programme structure. In this chapter we will analyse the problems related with the design of a post-graduation (MA, MSc or PhD) programme in the field of TA using as reference some international experiences. Hereby, the main conclusion seems to address labour market needs in the specialised knowledge of TA, of technology management or technology innovation. In this sense TA should be included as “minor” into post-graduation courses which may range from engineering disciplines to social sciences. As a graduation programme it can fill an expertise gap between technicians, engineers, scientists and the strategic decision makers or policy makers.

Congenital cytomegalovirus infection in a neonatal intensive care unit in Brazil evaluated by PCR and association with perinatal aspects

Cytomegalovirus (CMV) infection is the most common congenital infection, affecting 0.4% to 2.3% newborns. Most of them are asymptomatic at birth, but later 10% develop handicaps, mainly neurological disturbances. Our aim was to determine the prevalence of CMV shed in urine of newborns from a neonatal intensive care unit using the polymerase chain reaction (PCR) and correlate positive cases to some perinatal aspects. Urine samples obtained at first week of life were processed according to a PCR protocol. Perinatal data were collected retrospectively from medical records. Twenty of the 292 cases (6.8%) were CMV-DNA positive. There was no statistical difference between newborns with and without CMV congenital infection concerning birth weight (p=0.11), gestational age (p=0.11), Apgar scores in the first and fifth minutes of life (p=0.99 and 0.16), mother's age (p=0.67) and gestational history. Moreover, CMV congenital infection was neither related to gender (p=0.55) nor to low weight (<2,500g) at birth (p=0.13). This high prevalence of CMV congenital infection (6.8%) could be due to the high sensitivity of PCR technique, the low socioeconomic level of studied population or the severe clinical status of these newborns.
