Estudio prospectivo del sector de transporte aéreo a 2020 y su impacto en sectores conexos

El análisis del sector se realizó entre 2006 y 2011 con los estados financieros de las tres aerolíneas con mayor representación en el mercado. El trabajo inicia con la elaboración de la historia de la aviación en Colombia, seguido de un análisis del sector, iniciando con un análisis de hacinamiento, a partir de los indicadores ROA y ROE; después se hace el análisis del panorama competitivo; se hace un análisis de las fuerzas del mercado, un análisis de competidores y por último un análisis en conjunto. En la segunda etapa de la investigación, se hace un análisis prospectivo del sector de transporte aéreo, calificando las variables más influyentes y su impacto en otros sectores de la economía nacional, después de lo anterior, se hace un análisis del sector por parte de los actores se construyen las hipótesis y una evaluación final de los posibles escenarios.

Constitutional judges (guarantee of the Constitution and responsibility)

My aim in this paper is to propose a reflection on the position and the importance that the constitutional judge has in the legal systems of contemporary constitutionalism. The figure of the judge responsible of protecting the Constitution is a key institution, without which we cannot understand the laws of constitutional democracies, their current lines of development, and the guarantee of rights and freedoms that constitute the normative core of these systems. Moreover, the reflection on the exercise of the powers of the judge, its scope and its justification is an important part of contemporary legal discussion, still relevant, albeit not exclusively - in the field of legal philosophy. The object of attention of my reflection is the judge who has the power of judicial review, in a scheme of defense of the Constitution, regardless the specific ways of this defense.

Brain injury: Assessment of hemineglect occurence and of attentional deficit through cancellation tasks

Hemineglect (HN) is a widely studied syndrome after unilateral lesions due to stroke. However, although there are some studies with HN rehabilitation of posttraumatic brain injury (TBI), there seems to be no published data about the prevalence of HN in TBI through cancellation tasks. Thus, the objective of this study was to characterize the occurrence of this syndrome and of attentional deficits in patients with TBI by means of the Bells Test and of a line cancellation task. The sample was comprised of 21 patients with TBI and 21 healthy controls matched by education, age and frequency of written language habits. There was a poorer performance of patients with TBI with a greater number of omissions on the left side and lower speed processing. In addition, suggestive signs of HN were found in 38 % of the sample of TBI patients. More research is needed to characterize clinical syndromes regarding the occurrence of HN after a TBI through the traditionally known cancellation paradigm.
