The profile of general practitioners (GPs) who publish in selected family practice journals

Background: Providing support for research is one of the key issues in the ongoing attempts to improve Primary Care. However, when patient care takes up a significant part of a GP's time, conducting research is difficult. In this study we examine the working conditions and profile of GPs who publish in three leading medical journals and propose possible remedial policy actions. Findings: The authors of all articles published in 2006 and 2007 in three international Family Medicine journals - Annals of Family Medicine, Family Practice, and Journal of Family Practice - were contacted by E-mail. They were asked to complete a questionnaire investigating the following variables: availability of specific time for research, time devoted to research, number of patients attended, and university affiliation. Only GPs were included in the study. Three hundred and ten relevant articles published between 2006 and 2007 were identified and the authors contacted using a survey tool. 124 researchers responded to our questionnaire; 45% of respondents who were not GPs were excluded. On average GPs spent 2.52 days per week and 6.9 hours per day on patient care, seeing 45 patients per week. Seventy-five per cent of GPs had specific time assigned to research, on average 13 hours per week; 79% were affiliated to a university and 69% held teaching positions. Conclusions: Most GPs who publish original articles in leading journals have time specifically assigned to research as part of their normal working schedule. They see a relatively small number of patients. Improving the working conditions of family physicians who intend to investigate is likely to lead to better research results.

Web 2.0 en la docencia universitaria: aprendizaje colaborativo a través de la tecnología

El concepto web 2.0 se utiliza para denominar a un conjunto de aplicaciones que están siempre en evolución de acuerdo a los requerimientos que los usuarios van realizando. En la red podemos encontrar muchas herramientas desarrolladas en la línea de la web 2.0: blogs, wikis, herramientas para compartir marcadores, para compartir archivos, etc. Consideramos que el sistema educativo no puede estar al margen de esta evolución tecnológica y necesita adaptarse a todos los niveles. Las universidades también se encuentran en la necesidad de adecuarse a estos nuevos tiempos, y cada vez encontramos más experiencias formativas de trabajo colaborativo en red para favorecer el aprendizaje de los estudiantes. El trabajo que presentamos es un análisis de herramientas web 2.0 y de una recopilación de buenas prácticas docentes universitarias de desarrollo de metodologías colaborativas utilizando las TIC. Además, ofrecemos recomendaciones del uso de estas herramientas en los procesos de enseñanza y aprendizaje universitario.

Condicionantes contextuales de las atribuciones de los profesores respecto al rendimiento de sus alumnos

El estudio se centró en la hipótesis de que los profesores que enseñan en contextos de enseñanza obligatoria realizarán atribuciones de responsabilidad por los resultados de sus alumnos más internas que los que lo hacen en contextos de enseñanza selectiva. Se aplicó la escala Responsibility for Student Achievement (RSA) de Guskey (1981) a un grupo piloto de profesores de Primaria (n = 86) y a otro de Secundaria (n = 308), éste último incorporando profesorado de los niveles selectivos y obligatorios. Los resultados obtenidos tienden a confirmar la hipótesis de que los profesores de Primaria y los que enseñan mayoritariamente en la enseñanza Secundaria Obligatoria realizan atribuciones más internas que los profesores que enseñan mayoritariamente en la enseñanza Secundaria selectiva. Se discute la interpretación y las ímplicaciones de los resultados.

The membrane-permeable calmodulin inhibitors (W-7/W-13) bind to membranes changing the electrostatic surface potential. Dual effect of W-13 on EGFR activation

Membrane-permeable calmodulin inhibitors, such as the napthalenesulfonamide derivatives W-7/W-13, trifluoperazine, and calmidazolium, are used widely to investigate the role of calcium/calmodulin (Ca2+/CaM) in living cells. If two chemically different inhibitors (e.g. W-7 and trifluoperazine) produce similar effects, investigators often assume the effects are due to CaM inhibition. Zeta potential measurements, however, show that these amphipathic weak bases bind to phospholipid vesicles at the same concentrations as they inhibit Ca 2 /CaM; this suggests that they also bind to the inner leaflet of the plasma membrane, reducing its negative electrostatic surface potential. This change will cause electrostatically bound clusters of basic residues on peripheral (e.g. Src and K-Ras4B) and integral (e.g. epidermal growth factor receptor (EGFR)) proteins to translocate from the membrane to the cytoplasm. We measured inhibitor-mediated translocation of a simple basic peptide corresponding to the calmodulin-binding juxtamembrane region of the EGFR on model membranes; W-7/W-13 causes translocation of this peptide from membrane to solution, suggesting that caution must be exercised when interpreting the results obtained with these inhibitors in living cells. We present evidence that they exert dual effects on autophosphorylation of EGFR;W-13 inhibits epidermal growth factordependent EGFR autophosphorylation under different experimental conditions, but in the absence of epidermal growth factor, W-13 stimulates autophosphorylation of the receptor in four different cell types. Our interpretation is that the former effect is due toW-13inhibition of Ca 2 /CaM, but thelatter results could be due to binding of W-13 to the plasma membrane.

La autoeficacia docente e investigadora del profesorado universitario: relación con su estilo docente e influencia en sus concepciones sobre el nexo docencia-investigación

The aim of this paper was to explore whether self-efficacy as teacher and researcher perceived by university lecturers was related to teaching styles and approaches. Two instruments were administered to 259 teachers at the University of Girona (Spain), who were active researchers and had a teaching workload of 9 ECTS or above. The results showed that self-efficacy as a researcher was the variable which yielded most differences. The higher the self-efficacy of the researcher, the stronger the belief that teaching was guided by research. Certain beliefs about the teaching-research nexus were very different according to the degree of self-efficacy as a researcher, while there were fewer differences in terms of gender and field of study

Acción interpretativa para la finca pública de son real Mallorca

Cualquier acción dinamizadora que tenga como objetivo la desestacionalización turística basada en la explotación del patrimonio de la finca pública de Son Real, debe sustentarse necesariamente en una política gestora explícita, dotada de contenidos e integral.Pero ante todo debe tener una base de conocimiento, de contextualización del territorio y debe recoger todas las incidencias que afectan al bien para desarrollar estrategias consecuentes destinadas al conocimiento, conservación y difusión de este patrimonio, ligándolo a las demandas y necesidades de la sociedad actual y futura.
