Cosas de escuela: Aproximaciones a la vida cotidiana escolar
Macera,Irene;
Ciencia, docencia y tecnolog?-a , 2011,
Abstract: this paper presents a possible trajectory to think, from a daily and subjective perspective, the ways in which the school again becomes made up as a public space from the constitution of relationships produced by the subjects within it. it constitutes an analitical interpretative route where borders between private and public events seem displaced turning the school image diffused. testimonies collected during the methodological course of the study were registered and situationally analized, confrontated and put into tension within the space of the collective inquiry.
Cosas de escuela. Aproximaciones a la vida cotidiana escolar
Irene Macera
Ciencia, Docencia y Tecnología , 2011,
Abstract: Este artículo presenta, desde una perspectiva cotidiana y subjetiva, un recorrido posible para pensar los modos en que la escuela vuelve a componerse como lugar público desde la construcción de relaciones que producen los sujetos que la habitan. Es un recorrido interpretativo analítico donde se advierten fronteras desplazadas entre los asuntos privados y públicos que hacen de lo escolar una imagen difusa. Se presenta un registro y un análisis situacional acerca de testimonios recogidos durante el proceso metodológico de la investigación en curso, puestos en intercambio y tensión en el "espacio de indagación colectiva" del mismo.
Un estudio de las concepciones docentes acerca de la formación permanente Um estudo das concep es docentes sobre a forma o permanente A Survey of Teachers' Thoughts on Continuing Education

Educación y Educadores , 2012,
Abstract: Este trabajo presenta las concepciones docentes acerca de su formación permanente. Se identificaron distintos puntos de análisis relacionados con la antigüedad en la profesión, intereses metodológicos, intereses de actualización de conocimientos, intereses de incorporación de nuevos saberes y, por último, el lugar que ocupa la formación en la subjetividad docente. En los inicios de la docencia, la formación permanente funciona y se concibe como un modo de mantenerse activos mientras se insertan en el mercado laboral. En cambio, para los docentes que ya tienen una trayectoria, esta se concibe como una fuga del trabajo, un recurso que en ocasiones le otorga sentido al trabajo, asumiendo de este modo un lugar subjetivo importante en el quehacer docente. Pero, cualquiera que sea la motivación, la adquisición de nuevos saberes es la razón más antigua que los docentes asumen para formarse. Este trabalho apresenta as concep es docentes sobre sua forma o permanente. Identificaram-se diferentes pontos de análise relacionados com a antiguidade na profiss o, interesses metodológicos, interesses de atualiza o de conhecimentos, interesses de incorpora o de novos saberes e, por último, o lugar que a forma o ocupa na subjetividade docente. No início da docência, a forma o permanente funciona e se concebe como um modo de se manterem ativos enquanto se inserem no mercado de trabalho. Em compensa o, para os docentes que já têm uma trajetória, esta se concebe como uma fuga do trabalho, um recurso que em ocasi es outorga sentido ao trabalho e assume, desse modo, um lugar subjetivo importante no fazer docente. Contudo, qualquer que seja a motiva o, a aquisi o de novos saberes é a raz o mais antiga que os docentes assumem para se formar. This study delves into what teachers think about their own continuing education. Different points of analysis are identified with respect to seniority in the profession, methodological interests, interest in updating know-how, interest in incorporating new knowledge and, finally, the place training occupies in the teacher's subjective thinking. At the onset of teaching, continuing education works and is conceived as a way to stay active while entering the job market. In contrast, for teachers who already have a history in the profession, it is viewed as an escape from work or a recourse that occasionally gives meaning to work, thus assuming an important subjective place in the teacher's vocation. Yet, regardless of the motivation, the acquisition of new knowledge is the most enduring reason teachers draw on to further their training

Abstract: the purpose of this paper is to investigate the export market orientation of a sample of brazilian exporters. the multi-item scale proposed by cadogan et al. (1999) was applied in brazil and its adjustment assessed. the results provided support for: a) reliability (internal consistency of the scale); b) dimensionality (the export market orientation construct has four dimensions); c) convergent validity (high correlations among independent measures of the construct). however, evidence for discriminant validity was partially provided, suggesting that it might exist better measures for the dimensions export intelligence and dissemination. similarly, only partial evidence was provided for nomological validity, that is, the correlation between export market orientation and export performance. despite the limitations of the model, the score of export market orientation was calculated for the brazilian sample. brazilian exporters scored above the average.

The agent increases the signal intensity of the normal liver, and to a lesser extent of the pancreas, adrenal glands, kidneys and myocardium, on T1-weighted imaging. The increase of the signal intensity on the T1 images allows better visualization of focal lesions, especially of those that are of non-hepatocitary origin such as metastases. For this reason the most important indication for the use of mangafodipir trisodium is in detecting liver metastases, especially when the information may influence therapeutic planning, which in many cases is surgical resection. New data show that this liver-specific contrast agent is accurate in detecting small lesions and in assessing the liver status following neoadjuvant chemotherapy, where other imaging techniques, such as CT and PET, fail. Other lesser indications for studies with mangafodipir trisodium are: in characterizing liver and pancreatic lesions; in identifying biliary leakage following bile duct and/or liver surgery; and possibly in the future in the assessment of the extent of myocardial damage.

Abstract: Introduction The purpose of this study was to examine trends in walking for transportation among U.S. adults and youth for Healthy People 2010 objective 22-14. The objective calls for increasing the proportion of trips of 1 mile or less made by walking to 25% for adults and 50% for youth. National transportation surveys are used to track national health objectives, but data interpretation and caveats to use have not been discussed in the public health literature to date. Methods Cross-sectional analyses at two time points used data from the 1995 Nationwide Personal Transportation Survey and the subsequent 2001 National Household Travel Survey. The populations of interest were U.S. civilian noninstitutionalized adults (aged 18 years and older) and youth (aged 5 to 15 years). Trends were reported for the percentage of walking trips of 1 mile or less for transportation (adults) and walking trips of 1 mile or less to school (youth) using 86,286 trips (1995) and 119,462 trips (2001) made by adults and 3114 trips (1995) and 4073 trips (2001) made by youth. Results Of trips of 1 mile or less, adults reported more walking in 2001 (21.2%; 95% confidence interval [CI], 20.5–21.9) than in 1995 (16.7%; CI, 15.9–17.5). For trips to school of 1 mile or less, youths also increased walking from 1995 (31.3%; CI, 27.9–34.4) to 2001 (35.9%; CI, 33.0–38.8). Changes in survey methodology affected the interpretation of the Healthy People 2010 trends. Conclusion In spite of small increases in walking between 1995 and 2001 accompanying a change in survey methodology, U.S. adults and youth fall short of meeting Healthy People 2010 walking objectives for trips of 1 mile or less.

Abstract: Introduction The health benefits of regular cardiovascular exercise are well-known. Such exercise, however, has traditionally been defined as vigorous physical activity, such as jogging, swimming, or aerobic dance. Exercise of moderate intensity also promotes health, and many U.S. adults may be experiencing the health benefits of exercise through lifestyle activities of moderate intensity, such as yard work, housework, or walking for transportation. Until recently, public health surveillance systems have not included assessments of this type of physical activity, focusing on exercise of vigorous intensity. We used an enhanced surveillance tool to describe the prevalence and amount of both moderate-intensity and vigorous-intensity physical activity among U.S. adults. Methods We analyzed data from the 2001 Behavioral Risk Factor Surveillance System, a state-based, random-digit dialed telephone survey administered to U.S. adults aged 18 years and older (n = 82,834 men and 120,286 women). Physical activity behavior was assessed using questions designed to quantify the frequency of participation in moderate- or vigorous-intensity physical activities performed during leisure time or for household chores and transportation. Results Overall, 45% of adults (48% of men and 43% of women) were active at recommended levels during nonworking hours (at least 30 minutes five or more days per week in moderate-intensity activities, equivalent to brisk walking, or at least 20 minutes three or more days per week in vigorous activities, equivalent to running, heavy yard work, or aerobic dance). Less than 16% of adults (15% of men and 17% of women) reported no moderate or vigorous activity in a usual week. Conclusion Integrating surveillance of lifestyle activities into national systems is possible, and doing so may provide a more accurate representation of the prevalence of recommended levels of physical activity. These results, however, suggest that the majority of U.S. adults are not active at levels associated with the promotion and maintenance of health.
