Escola e diversidade cultural dos alunos: Um estudo no 1º ciclo do ensino básico

Portugal não foi exceção à globalização do mundo e hoje é procurado por povos de toda a parte. A diferença cultural destes povos/minorias reflete-se nas escolas a partir do 1.° Ciclo do Ensino Básico (CEB). No enquadramento teórico de vários autores sobre educação inter/ multicultural para as minorias, abordámos questões sobre a "Sociedade Inter/ Multicultural, Escola Multicultural”, a "Educação Multicultural", e a "Autonomia da escola e gestão do Currículo”. Focalizámos o estudo na "Escola e Minorias étnicas”, na relação da escola com, "estereótipos, preconceitos e atitudes” na sua inter ação com a comunidade e estudámos o caso concreto da escola e a etnia cigana. No estudo empírico, através de um questionário, recolhemos a opinião dos docentes de seis concelhos do distrito de Évora de Escolas do 1.° CEB, sobre as ”Práticas Educativas Desejáveis" e “Existentes” nas escolas em relação a estes alunos. Os resultados obtidos levam-nos a concluir que as práticas educativas existentes não respeitam totalmente a cultura dos alunos de minorias/ciganos mas que existe uma sensibilização para práticas educativas que transformem a escola numa escola multicultural. /ABSTRACT - School and Student's Cultural Diversity Portugal was not exception to the world's globalization and today is looked by peoples (ethnic minorities) of all different places. The cultural difference of these peoples/minorities reflects in the schools since 1.st degree (1. ° Ciclo do Ensino Básico). In the theoretical part of several authors on inter/multicultural education for the minorities, we approached questions on the "Inter/Multicultural Society,” Multicultural School", "School and multicultural education", the "School’s autonomy, curriculum management and multicultural education". We focused the study on the "gypsies" (ethnic minority) approaching questions of´Minority ethnic and school” and "School, Preconceptions and Stereotypes". In the empirical study, through a questionnaire, we collected the opinion of the professors of 1.st degree, from six councils (concelhos) of Évora's district, on "Desirable Educative Practice" and "the Existing ones" in the schools in relation to these pupils. The gotten results take us to conclude that the existing educative practice do not totally respect the culture of the pupils of minorities/gypsies but that exists a sensibilization for educative practice that transform the school into a multicultural school.

Immunological disturbance in West and Lennox-Gastaut syndromes

Investigamos a imunidade humoral e celular em 18 pacientes com sindrome de West, 12 com sindrome de Lennox-Gastaut e 19 controles. Os exames realizados foram os seguintes: percentagem de linfócitos Ô e  no sangue periférico, niveis séricos de IgG, IgA e IgM, sensibilização cutânea com o DNCB, PHA intra dérmica, teste de inibição de migração de leucócitos e transformação blástica de linfócitos em presença de PHA. Detectamos deficiência de imunidade celular em 28 crianças, (18 com sindrome de West e 10 com sindrome de Lennox-Gastaut) e baixos níveis de imunoglobulinas em apenas 6. A depressão imunitária mostrou-se mais intensa nas crianças que apresentam sindrome de West.

Some effects of gamma-irradiated autologous sera on their donors

The present paper is a further step to elucidate the effect of γ-irradiated molecules and their action as immunogens. Rabbits were bled, the total serum was γ-irradiated and reinjected to the autologous donor. Bleeding and reinjection of non-irradiated serum do not produce any alteration hence the animal is able to recognize the autologous unmodified serum proteins as 'self'. Electrophoretic results demonstrate that as an effect of γ-irradiation, alteration of the normal migration properties are occurring. The obtained data are suggesting that due to the possible alteration of the molecular structure, resulting as the effect of γ-rays, the antibody forming system of the animal injected with irradiated autologous serum might recognize the substances as 'not self' what may be the possible reason of antibody formation. The presence of antibodies and probably their complexes with antigens are demonstrated by cutaneous sensibilization technics. The low level of the complement starting from the 7-9 days, the histological alteration of the kidney and the cardiac lesions are tempting to try an interpretation comparing these symptoms to those observed in serum sickness.

Influence of climate changes on cross allergies: possible involvement of pollen transglutaminase

Allergies are a complex of symptoms derived from altered IgE-mediated reactions of the immune system towards substances known as allergens. Allergic sensibilization can be of food or respiratory origin and, in particular, apple and hazelnut allergens have been identified in pollens or fruits. Allergic cross-reactivity can occur in a patient reacting to similar allergens from different origins, justifying the research in both systems as in Europe a greater number of people suffers from apple fruit allergy, but little evidence exists about pollen. Apple fruit allergies are due to four different classes of allergens (Mal d 1, 2, 3, 4), whose allergenicity is related both to genotype and tissue specificity; therefore I have investigated their presence also in pollen at different time of germination to clarify the apple pollen allergenic potential. I have observed that the same four classes of allergens found in fruit are expressed at different levels also in pollen, and their presence might support that the apple pollen can be considered allergenic as the fruit, deducing that apple allergy could also be indirectly caused by sensitization to pollen. Climate changes resulting from increases in temperature and air pollution influence pollen allergenicity, responsible for the dramatic raise in respiratory allergies (hay fever, bronchial asthma, conjunctivitis). Although the link between climate change and pollen allergenicity is proven, the underlying mechanism is little understood. Transglutaminases (TGases), a class of enzymes able to post-translationally modify proteins, are activated under stress and involved in some inflammatory responses, enhancing the activity of pro-inflammatory phospholipase A2, suggesting a role in allergies. Recently, a calcium-dependent TGase activity has been identified in the pollen cell wall, raising the possibility that pollen TGase may have a role in the modification of pollen allergens reported above, thus stabilizing them against proteases. This enzyme can be involved also in the transamidation of proteins present in the human mucosa interacting with surface pollen or, finally, the enzyme itself can represent an allergen, as suggested by studies on celiac desease. I have hypothesized that this pollen enzyme can be affected by climate changes and be involved in exhacerbating allergy response. The data presented in this thesis represent a scientific basis for future development of studies devoted to verify the hypothesis set out here. First, I have demonstrated the presence of an extracellular TGase on the surface of the grain observed either at the apical or the proximal parts of the pollen-tube by laser confocal microscopy (Iorio et al., 2008), that plays an essential role in apple pollen-tube growth, as suggested by the arrest of tube elongation by TGase inhibitors, such as EGTA or R281. Its involvement in pollen tube growth is mainly confirmed by the data of activity and gene expression, because TGase showed a peak between 15 min and 30 min of germination, when this process is well established, and an optimal pH around 6.5, which is close to that recorded for the germination medium. Moreover, data show that pollen TGase can be a glycoprotein as the glycosylation profile is linked both with the activation of the enzyme and with its localization at the pollen cell wall during germination, because from the data presented seems that the active form of TGase involved in pollen tube growth and pollen-stylar interaction is more exposed and more weakly bound to the cell wall. Interestingly, TGase interacts with fibronectin (FN), a putative SAMs or psECM component, inducing possibly intracellular signal transduction during the interaction between pollen-stylar occuring in the germination process, since a protein immunorecognised by anti-FN antibody is also present in pollen, in particular at the level of pollen grain cell wall in a punctuate pattern, but also along the shank of the pollen tube wall, in a similar pattern that recalls the signal obtained with the antibody anti TGase. FN represents a good substrate for the enzyme activity, better than DMC usually used as standard substrate for animal TGase. Thus, this pollen enzyme, necessary for its germination, is exposed on the pollen surface and consequently can easily interact with mucosal proteins, as it has been found germinated pollen in studies conducted on human mucus (Forlani, personal communication). I have obtained data that TGase activity increases in a very remarkable way when pollen is exposed to stressful conditions, such as climate changes and environmental pollution. I have used two different species of pollen, an aero allergenic (hazelnut, Corylus avellana) pollen, whose allergenicity is well documented, and an enthomophylus (apple, Malus domestica) pollen, which is not yet well characterized, to compare data on their mechanism of action in response to stressors. The two pollens have been exposed to climate changes (different temperatures, relative humidity (rH), acid rain at pH 5.6 and copper pollution (3.10 µg/l)) and showed an increase in pollen surface TGase activity that is not accompanied to an induced expression of TGase immunoreactive protein with AtPNG1p. Probably, climate change induce an alteration or damage to pollen cell wall that carries the pollen grains to release their content in the medium including TGase enzyme, that can be free to carry out its function as confirmed by the immunolocalisation and by the in situ TGase activity assay data; morphological examination indicated pollen damage, viability significantly reduced and in acid rain conditions an early germination of apple pollen, thus possibly enhancing the TGase exposure on pollen surface. Several pollen proteins were post-translationally modified, as well as mammalian sPLA2 especially with Corylus pollen, which results in its activation, potentially altering pollen allergenicity and inflammation. Pollen TGase activity mimicked the behaviour of gpl TGase and AtPNG1p in the stimulation of sPLA2, even if the regulatory mechanism seems different to gpl TGase, because pollen TGase favours an intermolecular cross-linking between various molecules of sPLA2, giving rise to high-molecular protein networks normally more stable. In general, pollens exhibited a significant endogenous phospholipase activity and it has been observed differences according to the allergenic (Corylus) or not-well characterized allergenic (Malus) attitude of the pollen. However, even if with a different intensity level in activation, pollen enzyme share the ability to activate the sPLA2, thus suggesting an important regulatory role for the activation of a key enzyme of the inflammatory response, among which my interest was addressed to pollen allergy. In conclusion, from all the data presented, mainly presence of allergens, presence of an extracellular TGase, increasing in its activity following exposure to environmental pollution and PLA2 activation, I can conclude that also Malus pollen can behave as potentially allergenic. The mechanisms described here that could affect the allergenicity of pollen, maybe could be the same occurring in fruit, paving the way for future studies in the identification of hyper- and hypo- allergenic cultivars, in preventing environmental stressor effects and, possibly, in the production of transgenic plants.

Campañas de sensibilización para la conciliación de la vida laboral y familiar: una propuesta de investigación para la igualdad de género

From a gender perspective, protection and advertising political actions about work-family should promote sharing responsibilities between sexes. Next to political action and specific measures, the project of equal opportunities needs a long-term strategy based on the education on equality. This article proposes the methodologic exposition of a study based on these premises. It facilitates and explains the protocol used for the analysis of the audio-visual advertising campaigns on conciliation emitted by the Woman’s Institute. The evaluation of the actions is focused on the effectiveness from the point of view of mass media. It provides some data that illustrates the proposed study. Finally, it considers the difficulties of the available sources of information.

A contribuição da educação ambiental para uma compreensão ética da relação entre indivíduos humanos e cães: inferências teóricas a partir de um estudo de caso no município de Rio Grande-RS

A presente pesquisa teve como problemática o cão abandonado, e fez a relação entre esta situação e os processos humanos e culturais que perpassam o problema. A questão central da pesquisa é: Como compreender a relação dos humanos com os cães, e como a Educação Ambiental pode contribuir para a construção da reflexão sobre o tema e a consequente mudança de postura dos humanos para com estes animais em seu convívio social? O foco da pesquisa é a ética entendida como ética da vida a partir de autores como Morin, Singer e Brugger. O objetivo da pesquisa é contribuir para a construção de uma nova mentalidade; fazer perceber uma ética que não está clara, e buscar compreender os processos que afastem os humanos desta mentalidade. Sendo assim, a fundamentação teórica concentra - se em estudos sobre a ética, a domesticação e o antropocentrismo. Justifico este trabalho por tratar de uma situação degradante para com a vida deste animal, por seu valor intrínseco, e por ser um animal que, em minha opinião, acompanhou e refletiu a própria história da humanidade. A metodologia utilizada foi o Estudo de Caso, aplicado na cidade de Rio Grande, entre 2011 e 2013, e contou com entrevistas com grupos de proteção animal, e com o atual prefeito municipal. Como ferramenta metodológica, para a realização da pesquisa e do texto, utilizei a Mandala Reflexiva, da Prof. Dra. Virginia Machado, que é uma configuração de abordagem pedagógica e epistemológica do processo de investigação. A interação da pesquisa, além do resultado da atividade com alunos jovens e adultos da 8ª série do PROMEJA de uma escola municipal, envolveu a proposta da produção de vídeos amadores de sensibilização sobre o tema, para ser aplicada em escolas ou em quaisquer tipos de projetos com interessados sobre o tema, a fim de difundir a questão a partir da experiência ético - estética. O resultado prático é o registro de uma nova expectativa em relação à resolução do problema dos cães abandonados nesta cidade. Filosoficamente, chegou - se a uma reflexão complexa sobre o ser humano e suas ações no planeta, que indicam que, quanto mais formos capazes de pensar no todo, e substituir o egoísmo por uma dosagem de altruísmo e de ética, mais sentido terá a nossa própria vida.

Instrumentos de apoio à gestão estratégica e ao desempenho organizacional dos fisioterapeutas em unidades privadas de fisioterapia

O sucesso de uma gestão baseada na estratégia reside, no aproveitamento racional e eficiente dos seus recursos humanos, financeiros e organizacionais, bem como na sua capacidade para concretizar objectivos e alcançar resultados. Esta dissertação foi elaborada baseando-se no pressuposto que, a selecção e a aplicação de um Instrumento de Apoio à Gestão em unidades privadas de fisioterapia (UPF’s) permitirão induzir níveis acrescidos de melhoria do desempenho individual e/ou organizacional. Constituiu objectivo geral da mesma contribuir para a sensibilização e a difusão alargada das ferramentas de apoio à gestão que, aplicadas naquelas unidades, poderiam induzir níveis acrescidos de melhoria do desempenho. Definiram-se ainda três objectivos específicos consubstanciando preocupações relacionadas com a reprodução do conhecimento especializado em gestão, com a sua aplicação específica no terreno e com a subjacente criação de valor individual e organizacional. A metodologia utilizada foi a abordagem de Estudo de Caso, inspirada na técnica focus-group, aplicada a três UPF’s, e os resultados obtidos através das análises efectuadas permitiram identificar a ausência da aplicação de instrumentos de apoio à gestão e de avaliação de desempenho, bem como níveis elevados de desempenho, satisfação e autonomia nos profissionais de fisioterapia, constituindo estes a base para justificar a necessidade urgente da elaboração de um plano de implementação de um sistema de avaliação de desempenho nas unidades estudadas. /ABSTRACT: The success of a management based on strategy relies in the rational and efficient use of its human, financial and organizational resources, as well as its ability to achieve objectives and results. This thesis was developed, based on the assumption that the selection and application of a management support instrument in private physiotherapy units would induce higher levels of individual performance and / or organization. It was general objective the contribution to the sensibilization and diffusion of tools to support management, which applied in those units, could induce higher levels of performance. There were defined three specific objectives which concerned whereabouts with the reproduction of specialized knowledge in management, with its specified applicability in the work field and with the underneath creation of individual and organizational value. The applied methodology was a case study, inspired by the focus-group technique applied in three private physiotherapy units, and the results obtained through the analysis allowed the identification of lack of use of any support management tools and performance evaluation, as well as high standard levels of performance, satisfaction and professional autonomy in physical therapists, being this the base for justifying the urgent need for developing an implementation plan of a performance evaluation system applied to these units.
