Productividad del recurso humano de ciencia y tecnología en Colombia 1990-2004

El documento estudia los determinantes de la productividad del recurso humano dedicado a actividades de C&T en Colombia. A partir de la medición que realizó Colciencias en el año 2004 para la clasificación de grupos a nivel nacional, se encuentra que el nivel de formación del investigador tiene impacto en la productividad del grupo, al igual que las relaciones sociales complejas dadas por la preferencia de trabajo con los investigadores que tienen más prestigio dentro del grupo, ya que esto ofrece la posibilidad de generar mayores habilidades a los investigadores de menor clasificación. El segundo análisis se realiza a partir de la información de los becarios de estudios de postgrado en el exterior de Colciencias y utilizando los datos de su CvLac, encontrando que variables como el nivel de formación y el manejo de idiomas son determinantes de la productividad del investigador y que para Colombia, el área de conocimiento del investigador no son referentes a su productividad.

Educational resources offered by the European Board of Physical and Rehabilitation Medicine (EBPRM)

Background .- Physical and Rehabilitation Medicine (PRM) is a very demanding medical speciality. To ensure high standard of research and care in PRM all across Europe, it is crucial to attract gifted trainees and offer them high quality education. At undergraduate level, many medical schools in Europe omit to offer teaching on disabled persons and on basic PRM knowledge. Thus PRM is hardly known to medical students. For postgraduate trainees access to evidence-based knowledge as well as teaching of research methodology specific to PRM, rehabilitation methodology, disability management and team building also need to be strengthened to increase the visibility of PRM. Action .- To address these issues the EBPRM proposes presently a specific undergraduate curriculum in PRM including the issues of disability, participation and handicap as a basis for general medical practice and postgraduate rehabilitation training. For PRM trainees many educational documents are now available on the EBPRM website. A growing number of educational sessions for PRM trainees take place during international and national PRM Congresses which can be accessed at low cost. Educational papers published regularly in European rehabilitation journals and European PRM Schools are offered free or at very low cost to trainees.

Deep molecular response is reached by the majority of patients treated with imatinib, predicts survival, and is achieved more quickly by optimized high-dose imatinib: results from the randomized CML-study IV

PURPOSE Deep molecular response (MR(4.5)) defines a subgroup of patients with chronic myeloid leukemia (CML) who may stay in unmaintained remission after treatment discontinuation. It is unclear how many patients achieve MR(4.5) under different treatment modalities and whether MR(4.5) predicts survival. PATIENTS AND METHODS Patients from the randomized CML-Study IV were analyzed for confirmed MR(4.5) which was defined as ≥ 4.5 log reduction of BCR-ABL on the international scale (IS) and determined by reverse transcriptase polymerase chain reaction in two consecutive analyses. Landmark analyses were performed to assess the impact of MR(4.5) on survival. RESULTS Of 1,551 randomly assigned patients, 1,524 were assessable. After a median observation time of 67.5 months, 5-year overall survival (OS) was 90%, 5-year progression-free-survival was 87.5%, and 8-year OS was 86%. The cumulative incidence of MR(4.5) after 9 years was 70% (median, 4.9 years); confirmed MR(4.5) was 54%. MR(4.5) was reached more quickly with optimized high-dose imatinib than with imatinib 400 mg/day (P = .016). Independent of treatment approach, confirmed MR(4.5) at 4 years predicted significantly higher survival probabilities than 0.1% to 1% IS, which corresponds to complete cytogenetic remission (8-year OS, 92% v 83%; P = .047). High-dose imatinib and early major molecular remission predicted MR(4.5). No patient with confirmed MR(4.5) has experienced progression. CONCLUSION MR(4.5) is a new molecular predictor of long-term outcome, is reached by a majority of patients treated with imatinib, and is achieved more quickly with optimized high-dose imatinib, which may provide an improved therapeutic basis for treatment discontinuation in CML.

The FaceUOC Project : An Open Social Learning experience by the Open University of Catalonia

The possibilities and expansion of the use of Web 2.0 has opened up a world of possibilities in online learning. In spite of the integration of these tools in education major changes are required in the educational design of instructional processes.This paper presents an educational experience conducted by the Open University of Catalonia using the social network Facebook for the purpose of testing a learning model that uses a participation and collaboration methodology among users based on the use of open educational resources.- The aim of the experience is to test an Open Social Learning (OSL) model, understood to be a virtual learning environment open to the Internet community, based on the use of open resources and on a methodology focused on the participation and collaboration of users in the construction of knowledge.- The topic chosen for this experience in Facebook was 2.0 Journeys: online tools and resources. The objective of this 5 weeks course was to provide students with resources for managing the various textual, photographic, audiovisual and multimedia materials resulting from a journey.- The most important changes in the design and development of a course based on OSL are the role of the teacher, the role of the student, the type of content and the methodology:- The teacher mixes with the participants, guiding them and offering the benefit of his/her experience and knowledge.- Students learn through their participation and collaboration with a mixed group of users.- The content is open and editable under different types of license that specify the level of accessibility.- The methodology of the course was based on the creation of a learning community able to self-manage its learning process. For this a facilitator was needed and also a central activity was established for people to participate and contribute in the community.- We used an ethnographic methodology and also questionnaires to students in order to acquire results regarding the quality of this type of learning experience.- Some of the data obtained raised questions to consider for future designs of educational situations based on OSL:- Difficulties in breaking the facilitator-centred structure- Change in the time required to adapt to the system and to achieve the objectives- Lack of commitment with free courses- The trend to return to traditional ways of learning- Accreditation- This experience has taught all of us that education can happen any time and in any place but not in any way.

Factores asociados al no deseo del primer embarazo en adolescentes gestantes colombianas. Estudio exploratorio de la ENDS 2010

Introducción: El inicio de la vida sexual dispone a las jóvenes a sufrir de las consecuencias inherentes de esta actividad, entre ellas, el embarazo no deseado. Para efectos del presente estudio, se indago en el contexto nacional la asociación del no deseo del primer embarazo en adolescentes gestantes con diversos factores sociodemográficos, individuales y de servicios de salud. Metodología: Estudio exploratorio, descriptivo y analítico; la población estudiada proviene de la Encuesta Nacional de Demografía y Salud 2010. La selección de la población tuvo como criterio a mujeres menores de 20 años, que cursan con su primer embarazo al momento de la encuesta. Se realizaron análisis descriptivos, comparativos y asociativos. Resultados: Se seleccionaron 286 adolescentes colombianas en estado de su primer embarazo. 71,3% corresponden a embarazos no deseados y 28,7% a embarazos deseados al momento de la encuesta. Se encontró asociación estadística del no deseo del embarazo con la asistencia escolar actual OR 2.3 (IC95% 1.2 a 4.56), sentir que le ha hecho falta más educación sexual OR 1.94 (IC95% 1.11 a 3.36), decisión del embarazo en conjunto OR 0.05 (IC95% 0.02 a 0.1) y nivel educativo alto OR: 3.5 (IC 95% de 1,397 a 8,792). Conclusión: Existe asociación estadísticamente significativa del no deseo del embarazo y un nivel educativo alto alcanzado por la mujer y la edad del esposo. Se requieren de más estudios para verificar los demás resultados.
