Ensino da gramática: conceções, práticas, currículo e terminologia, currículo e terminologia

Com este texto, pretende-se apresentar alguns dos resultados de um estudo multicasos, que teve como objetivos de investigação: i) conhecer conceções dos professores de Língua Portuguesa do 2.º CEB em relação ao ensino e à aprendizagem da gramática; ii) conhecer opiniões desses professores em relação ao Dicionário Terminológico (DT); iii) conhecer opiniões desses professores face ao Conhecimento Explícito da Língua (CEL); iv) Conhecer práticas desses professores em relação ao ensino e à aprendizagem da gramática; v) e identificar necessidades de formação desses professores em relação ao ensino da gramática. O estudo, de natureza exploratória e inserido no paradigma interpretativo, teve como participantes seis professores de Português, língua materna, e seis turmas do 2.º CEB, de três escolas do distrito de Lisboa. A informação foi recolhida no ano letivo 2011 – 2012, através das técnicas da observação direta e da entrevista. Concluiu-se que nem sempre se verifica uma linearidade entre a prática e o discurso, tendo ocorrido situações de incoerência entre as práticas observadas e as manifestações verbais dos docentes em contexto de entrevista. Por outro lado, os professores reconheceram a importância do conhecimento gramatical e a sua influência no sucesso em outras competências do modo oral ou escrito. No entanto, nem todos valorizaram esse conhecimento do mesmo modo relativamente às restantes competências nucleares da língua. Os docentes revelaram, ainda, dificuldades ao nível da atualização exigida pelo tempo de transição em que vivem e do conhecimento científico e didático.

Shall I compare thee to an old man? A velhice em William Shakespeare e Rugénio de Andrade

A velhice é um tema que emerge com frequência nas obras de William Shakespeare e de Eugénio de Andrade, sempre num tom disfórico. Em ambos, a última das sete idades do ser humano, acarreta uma série de consequências negativas: a) A beleza é efémera e os amantes abandonam; b) O declínio físico e mental é inevitável; c) Na fase final da vida, sobrevém o temor da morte. Para expressarem o efeito da senectude, Shakespeare e Eugénio recorrem a comparações semelhantes entre o ser humano e o Outono (velhice) e o Inverno (morte). Neste artigo, numa perspectiva comparada e intertextual, exemplifico e analiso essas melancólicas e dolorosas imagens. Para tanto, recorro à obra dos dois escritores, à opinião de ensaístas reputados na área dos estudos literários e da psicologia da morte e, naturalmente, à minha opinião.

Seroprevalence of antibodies to Venezuelan equine encephalitis complex (subtypes IAB and VI) in humans from General Belgrano Island, Formosa, Argentina

This work presents the results of the detection of antibodies (immunoglobulin G) for subtypes I and VI of VEE viruses complex (Togaviridae family) in people from the General Belgrano island, Formosa province (Argentina). The prevalence of neutralizing (NT) antibodies for subtype VI was from 30% to 70% and the prevalence of antibodies inhibitory of hemagglutination (HI) was of 0% in the first and second inquiry respectively. For the subtype IAB the prevalence of NT antibodies was from 13% to 3.6%, similar to the prevalence total for both subtypes. HI antibodies were not detected in any inquiries for any subtype. It was observed that both subtypes circulate simultaneously, while subtype VI remains constant with some peaks, subtype I was found in low level.

Development and validation of a risk model for prediction of hazardous alcohol consumption in general practice attendees : the PredictAL study

Background: Little is known about the risk of progression to hazardous alcohol use in people currently drinking at safe limits. We aimed to develop a prediction model (predictAL) for the development of hazardous drinking in safe drinkers. Methods: A prospective cohort study of adult general practice attendees in six European countries and Chile followed up over 6 months. We recruited 10,045 attendees between April 2003 to February 2005. 6193 European and 2462 Chilean attendees recorded AUDIT scores below 8 in men and 5 in women at recruitment and were used in modelling risk. 38 risk factors were measured to construct a risk model for the development of hazardous drinking using stepwise logistic regression. The model was corrected for over fitting and tested in an external population. The main outcome was hazardous drinking defined by an AUDIT score >= 8 in men and >= 5 in women. Results: 69.0% of attendees were recruited, of whom 89.5% participated again after six months. The risk factors in the final predictAL model were sex, age, country, baseline AUDIT score, panic syndrome and lifetime alcohol problem. The predictAL model's average c-index across all six European countries was 0.839 (95% CI 0.805, 0.873). The Hedge's g effect size for the difference in log odds of predicted probability between safe drinkers in Europe who subsequently developed hazardous alcohol use and those who did not was 1.38 (95% CI 1.25, 1.51). External validation of the algorithm in Chilean safe drinkers resulted in a c-index of 0.781 (95% CI 0.717, 0.846) and Hedge's g of 0.68 (95% CI 0.57, 0.78). Conclusions: The predictAL risk model for development of hazardous consumption in safe drinkers compares favourably with risk algorithms for disorders in other medical settings and can be a useful first step in prevention of alcohol misuse.

A Communication Intervention for Training Southern European Oncologists to Recognize Psychosocial Morbidity in Cancer. I - Development of the Model and Preliminary Results on Physicians' Satisfaction

BACKGROUND: The detection of psychosocial distress is a significant communication problem in Southern Europe and other countries. Work in this area is hampered by a lack of data. Because not much is known about training aimed at improving the recognition of psychosocial disorders in cancer patients, we developed a basic course model for medical oncology professionals. METHODS: A specific educational and experiential model (12 hours divided into 2 modules) involving formal teaching (ie, journal articles, large-group presentations), practice in small groups (ie, small-group exercises and role playing), and discussion in large groups was developed with the aim of improving the ability of oncologists to detect emotional disturbances in cancer patients (ie, depression, anxiety, and adjustment disorders). RESULTS: A total of 30 oncologists from 3 Southern European countries (Italy, Portugal, and Spain) participated in the workshop. The training course was well accepted by most participants who expressed general satisfaction and a positive subjective perception of the utility of the course for clinical practice. Of the total participants, 28 physicians (93.3%) thought that had they been exposed to this material sooner, they would have incorporated the techniques received in the workshop into their practices; 2 participants stated they would likely have done so. Half of the doctors (n = 15) believed that their clinical communication techniques were improved by participating in the workshop, and the remaining half thought that their abilities to communicate with cancer patients had improved. CONCLUSIONS: This model is a feasible approach for oncologists and is easily applicable to various oncology settings. Further studies will demonstrate the effectiveness of this method for improving oncologists skills in recognizing emotional disorders in their patients with cancer.

The general practitioner and the surgeon: stereotypes and medical specialties

OBJECTIVE: To investigate and characterize the professional stereotypes associated with general medicine and surgery among Brazilian medical residents. METHODS: A randomized sample of residents of the General Medicine and Surgery Residence Programs were interviewed and their perceptions and views of general and surgical doctors were compared. RESULTS: The general practitioner was characterized by the residents in general to be principally a sensitive and concerned doctor with a close relationship with the patient; (45%); calm, tranquil, and balanced (27%); with intellectual skills (25%); meticulous and attentive to details (23%); slow to resolve problems and make decisions (22%); and working more with probabilities and hypotheses (20%). The surgeon was considered to be practical and objective (40%); quickly resolving problems (35%); technical with manual skills (23%); omnipotent, arrogant, and domineering (23%); anxious, stressed, nervous, and temperamental (23%); and more decided, secure, and courageous (20%). Only the residents of general medicine attributed the surgeon with less knowledge of medicine and only the surgeons attributed gender characteristics to their own specialty. CONCLUSION: There was considerable similarity in the description of a typical general practitioner and surgeon among the residents in general, regardless of the specialty they had chosen. It was interesting to observe that these stereotypes persist despite the transformations in the history of medicine, i.e. the first physicians (especially regarding the valorization of knowledge) and the first surgeons, so-called "barber surgeons" in Brazil (associated with less knowledge and the performance of high-risk procedures).

Can the dopaminergic-related effects of general anesthetics be linked to mechanisms involved in drug abuse and addiction?

BACKGROUND: General anesthetics (GA) are well known for the ability to induce a state of reversible loss of consciousness and unresponsiveness to painful stimuli. However, evidence from animal models and clinical studies show that GA exposure may induce behavioral changes beyond acute effects. Most research and concerns are focused on changes in cognition and memory. METHODS: We will look at effects of GA on behavior that is mediated by the dopaminergic system. RESULTS: Pharmacological resemblance of GA with drugs of abuse, and the complexity and importance of dopaminergic systems in both reward seeking and addictive illnesses make us believe that it deserves an overview about what is already known and what matters to us as healthcare workers and specifically as anesthesiologists. CONCLUSION: A review of available evidence strongly suggests that there may be a link between the effects of GA on the brain and substance abuse, partly explained by their influence on the dopaminergic system.

Proyecto integrado en el Area de Microelectrónica para el Diseño de circuitos integrados (Programa de Modernización Tecnológica III I-P - PAE 2006)

El objetivo general de este proyecto estratégico es incorporar una actividad de alto valor agregado como es el diseño de circuitos integrados dentro del segmento de alta tecnología de la cadena productiva nacional. Para ello resulta necesario cumplimentar los siguientes objetivos específicos:• Fortalecer los grupos de investigación y desarrollo que realizan tareas dentro de este área temática, tanto en infraestructura como en recursos humanos; • Fortalecer y desarrollar la Industria Electrónica mediante la incorporación de estas nuevas tecnologías en sus productos; • Representar y asistir a los grupos de diseño locales en la búsqueda de oportunidades para realizar “outsourcing” de diseño para compañías del exterior; • Establecer una primer masa crítica de diseñadores, que funcione como impulsora de la actividad en el medio; • Generar una red a nivel local, donde convivan empresas, universidades y profesionales. La mejora continua en las prestaciones de los productos y en los procesos productivos ha llevado a que la microelectrónica esté presente en los más diversos ámbitos de la actividad humana, con la perspectiva de ir incrementando constantemente su participación. Por eso mismo, un país que pretenda insertarse en el mundo de manera soberana no puede menospreciar la necesidad de incrementar la capacidad de su industria en el área. Los componentes de la Cadena de valor de la ME son los siguientes: • Diseño del circuito, con valor agregado de conocimientos y experiencia del diseñador; • Herramientas de Software de diseño (CAD) con verificación y simulación; • Prototipeo de circuitos y ensayo (testing); • Fabricación de chip en línea; •Encapsulado y testeo. Salvo el primer eslabón, los restantes requieren de una gran inversión en infraestructura, con una permanente actualización. Sin embargo, el Diseño de circuitos es perfectamente abordable en la Argentina, dado que solo requiere de conocimiento y experiencia, y se puede realizar sobre computadoras estándar.

Efecto de las Fenotiazinas sobre la vitalidad del <i>Trypanosoma cruzii>

La Enfermedad de Chagas, causada por el <i>Tripanosoma cruzii> es una parasitosis ampliamente difundida en los países latinoamericanos, constituyendo una patología con un intrincado problema bioecológico y político social. Dado que existen sólo dos drogas tripanocidas aprobadas por la Organización Mundial de la Salud (OMS) efectivas durante la fase aguda de la enfermedad (Nifrutimox, Benznidasol) y con un alto nivel de toxicidad, es que resulta de imperiosa necesidad la búsqueda de nuevos agentes terapéuticos que presenten menores riesgos y mayores beneficios para el paciente, así como para la quimioprofilaxis de la sangre a transfundir en zonas alejadas de centros de salud de complejidad. Hemos demostrado que algunas fenotiazinas, derivados tricíclicos y usados en la clínica psiquiátrica resultan letales sobre tripomastigotes y epimastigotes de <i>T. cruzii>, cepa Tulahuen, produciendo disrupción de membrana celular con liberación del contenido citoplasmático o disrupción de la mitocondria del parásito con la consiguiente alteración en la producción de ATP y la posterior muerte del mismo. Los ensayos "in vivo" han revelado ausencia o disminución de la parasitemia con importante sobrevida de los ratones infectados. El presente plan de trabajo tiene como objetivos: Continuar con los estudios de los efectos de derivados fenotiazínicos (Tioridazina) e iniciar el de otros compuestos (Propanolol), sobre la vitalidad del <i>T. cruzii> en diseños "in vitro" e "in vivo". El conocimiento de los mecanismos de acción de los compuestos señalados sobre la biología y composición química del parásito, así como sobre el huésped facilitará el hallazgo de potenciales agentes terapéuticos para la Enfermedad de Chagas experimental.
