The Digital Divide in the University: The Appropriation of ICT in Higher Education Students from Bogota, Colombia

The growth and integration of ICTs in the global economy have created conditions that profoundly affect our society, dividing communities between those who effectively appropriate these resources and those who do not, what is called the digital divide. This exploratory study seeks to propose and validate ways of assessing this phenomenon in higher education, from the construction of a model and a comprehensive methodology that value contextual conditions, in addition to measuring access factors and motivation for use, that have been employed in previous research. To obtain indications about the behavior of this phenomenon, we developed research with students from three universities in Bogota, administering 566 surveys in four phases that would test the variables proposed in the model. The results show that the variables of the model link causally, with the strongest relations between education, attitude towards ICTs and ICT application. Although students have good access to ICTs and high levels of education, no strong relationship was found in regards to perceived impact on production. This may be explained by a superficial appropriation of ICT, due to a context that is alien to its conditions of origin (industrialism, innovation), poor quality of education and economies not centered around R&D.

Selección del tratamiento farmacológico en el estado de mal epiléptico en niños

The status epilepticus (SE) is characterized by a series of crises which occur without recovery of consciousness or a single seizure lasting more than 30 minutes and can damage the central nervous system and systemic. The duration and frequency of attacks are directly related to patient prognosis. Whether seizures occur often and are longer, increase the risk of neurological and systemic complications. Child population has a higher frequency of seizures and it is associated with a lower threshold of immature brain to trigger these episodes. Aim: To determine the safest drugs prescribed for children in SE, their doses and schedules. A bibliographic survey was performed in electronic databases. Methods: The scientific health descriptors used for search was: “status epilecticus” and “anticonvulsivants” and “child”. Results: This strategy identified 396 manuscripts, of whom four were considered eligible for the study, after the assessment by floating reading and criteria. Of these, two were randomized trials and two descriptive. The studies address the use of oral midazolam, rectal diazepam and intravenous lorazepam. Conclusions: All investigated drugs were effective in treat in status epilepticus. Lorazepam is highlight, since it has fewer secondary effects and, as an alternative to the intravenous, oral midazolam. However, there is a need for further studies to demonstrate the efficacy and safety in the use of drugs in children.

Entrevista al Dr. Javier Santaolalla, ingeniero de telecomunicación y fisico español, participante en las investigaciones del boson Higgs en el CERN.

Entrevista a Javier Santaolalla investigador en el experimento del CERN que describió recientemente una nueva partícula: el bosón de Higgs, que trata de explicar el origen de la masa de las partículas elementales. La existencia del bosón de Higgs y su campo asociado intentan explicar la razón de la existencia de masa en las partículas elementales. El 4 de julio de 2012, el CERN anunció la observación de una nueva partícula «consistente con el bosón de Higgs», pero se necesitaría más tiempo y datos para confirmarlo. El 14 de marzo de 2013 el CERN, con dos veces más datos de los que disponía en el anuncio del descubrimiento en julio de 2012, encontraron que la nueva partícula se ve cada vez más como el bosón de Higgs. Javier Santaolalla es ingeniero de telecomunicación por la Universidad de las Palmas de Gran Canaria y licenciado en ciencias físicas por la Universidad Complutense de Madrid. Investigador del CIEMAT (Madrid) y Dr. por esta última universidad en ciencias físicas. El Dr. Javier Santaolalla se encuentra unos días de escala en Las Palmas de Gran Canaria procedente de Brasil y con destino a Ginebra. Le agradecemos cuantas facilidades nos ha proporcionado en la realización de la presente entrevista así como sus aportaciones.
