Entropic system of daily mobility in a Metropolitan Area of Bogota, Colombia.

The fundamental diseconomy in the large metropolitan areas is the significant and sustained increase in travel time incurred by its inhabitants daily. Since a portion of the energy consumed in the daily mobility does not necessarily translate into individual and collective wealth, entropic systems have a feature which, as discussed for the case of Bogotá, does not have metropolitan institutions with the ability to redirect.

Residential Mobility: a Sociological Concern

The aim of this paper is to present a theoretical-conceptual approach to residential mobility, in general, and residential trajectories, in particular. It seeks to understand how from the unequal distribution and appropriation of social resources —both material and symbolic— different trajectories are developed and how socio-territorial structures constrain, shape and enable interactions between families, their members and the various contexts of action towards meeting their housing needs. From sociological contributions of different traditions, we present a scheme that pays attention to articulating the relationship between structural factors, position in social structure and decisions elating to changes of residence. We conclude that mobility patterns are relational patterns that are defined in dialogue with the opportunities and limitations that are set up around the housing stock and new or vacant land, the land market dynamics and housing, the labor market, the provision of nfrastructure services and social facilities, etc.

Análisis de la producción escrita en revistas internacionales especializadas en terapia ocupacional (American Journal of Occupational Therapy – Canadian Journal of Occupational Therapy) sobre el concepto de desempeño ocupacional en el periodo comprendido entre 1996 – 2006

En todas las etapas de la vida, las personas se encuentran influenciadas por el ambiente, el cual es un facilitador o inhibidor para el desarrollo de sus actividades, permitiéndole elegir qué ocupaciones desea desempeñar de acuerdo a sus intereses y habilidades. Es por ello que el presente trabajo sustenta el objeto de estudio por medio de la revisión, análisis y reflexión de textos especializados en terapia ocupacional en el periodo comprendido entre 1996 – 2006, en las revistas Canadiense y Americana de Terapia Ocupacional, encontradas en la Biblioteca Ciencias de la Salud de la Universidad del Rosario.

Occupational therapy and its relevance in social projects. relationships, learning and opportunities: collection of experiences of University of Alberta Mscot students in Bogotá, Colombia

Occupational therapists are equipped to promote wellbeing through occupation and to enable participation and meaningful engagement of people in their social and physical environments (WFOT, 2012). As such, the role of the occupational therapists is profoundly linked to the social, cultural and environmental characteristics of the contexts in which occupations take place. The central role that context plays in occupational performance creates an interesting dichotomy for the occupational therapist: on one hand, a profound understanding of cultural and social factors is required from the Occupational Therapy (OT) in order to develop a meaningful and successful collaboration with the person; on the other hand, the ability of the occupational therapists to recognize and explore the contextual factor of an occupation-person dyad transcends cultural and spatial barriers. As a result, occupational therapists are equipped to engage in international collaboration and practice, and as such face unique and enriching challenges. International fieldwork experiences have become a tool through which occupational therapists in training can develop the critical skills for understanding the impact of cultural and social factors on occupation. An OT student in an international fieldwork experience faces numerous challenges in leading a process that is both relevant and respectful to the characteristics of the local context: language, cultural perceptions of occupation and personhood, religious backgrounds, health care access, etc. These challenges stand out as ethical considerations that must be considered when navigating an international fieldwork experience (AOTA, 2009). For more than five years now, the Faculty of Rehabilitation Medicine (FRM) of the University of Alberta (UoFA) and the School of Medicine and Health Sciences at the Universidad del Rosario (UR), Bogota, Colombia, have sustained a productive and meaningful international collaboration. This collaboration includes a visit by Dr. Albert Cook, professor of the FRM and former dean, to the UR as the main guest speaker in the International Congress of Technologies for Disability Support (IBERDISCAP) in 2008. Furthermore, Dr. Cook was a speaker in the research seminar of the Assistive Technology Research Group of the Universidad del Rosario. Following Dr. Cook’s visit, Professors Liliana Álvarez and Adriana Ríos travelled to Edmonton and initiated collaboration with the FRM, resulting in the signing of an agreement between the FRM and the UR in 2009, agreement that has been maintained to this day. The main goal of this agreement is to increase academic and cultural cooperation between the UR and the UofA. Other activities have included the cooperation between Dr. Kim Adams (who has largely maintained interest and effort in supporting the capacity building of the UR rehabilitation programs in coordinating the provision of research placement opportunities for UR students at the UofA), an Assistive Technology course for clinicians and students led by Dr. Adams, and a research project that researched the use of basic cell phones to provide social interaction and health information access for people with disabilities in a low-income community in Colombia (led by Tim Barlott, OT, MSc, under the supervision of Dr. Adams). Since the beginning, the occupational therapy programs of the Universidad del Rosario and the University of Alberta have promoted this collaboration and have strived to engage in interactions that provide further development opportunities for students and staff. As part of this process, the international placement experience of UofA OT students was born under the leadership of: Claudia Rozo, OT program director at UR, placement and academic leadership of Elvis Castro and Angélica Monsalve, professors of the occupational therapy program at UR; and Dr. Lili Liu, OT department director at UofA, Cori Schmitz, Academic coordinator of clinical education at the UofA; and Tim Barlott and Liliana Álvarez leading the international and cross-cultural aspect of this collaboration.This publication summarizes and illustrates the process of international placement in community settings in Colombia, undertaken by occupational therapy students of the University of Alberta. It is our hope that this document can provide and document the ethical considerations of international fieldwork experience, the special characteristics of communities and the ways in which cultural and social competences are developed and help international students navigate the international setting. We also hope that this document will stimulate discussion among professional and academic communities about the importance and richness of international placement experiences and encourage staff and students to articulate their daily efforts with the global occupational therapy agenda.

Estimaciones de los determinantes de los ingresos laborales en Colombia con consideraciones diferenciales para asalariados y cuenta propia

La literatura sobre determinantes de los ingresos laborales ha evolucionado en sus fundamentos teóricos, metodológicos y estimaciones empíricas. Colombia no ha sido ajena a este proceso, pero su evolución, notoria en fertilidad, ha venido relajándose en rigor conceptual: se tiende a considerar a los cuenta propia y asalariados como categorías relativamente semejantes. Para mostrar el efecto de dicha relajación realizamos estimaciones conjuntas de determinantes del ingreso laboral para ocupados asalariados y cuenta propia, y luego las contrastamos con estimaciones más detalladas y desagregadas ilustrando los sesgos efectivos que se generan si no se tienen en cuenta las características laborales de los ocupados cuenta propia y asalariado.

Conformations of poly{G}-poly{C} π stacks with high hole mobility

Charge transfer properties of DNA depend strongly on the π stack conformation. In the present paper, we identify conformations of homogeneous poly-{G}-poly-{C} stacks that should exhibit high charge mobility. Two different computational approaches were applied. First, we calculated the electronic coupling squared, V2, between adjacent base pairs for all 1 ps snapshots extracted from 15 ns molecular dynamics trajectory of the duplex G15. The average value of the coupling squared 〈 V2 〉 is found to be 0.0065 eV2. Then we analyze the base-pair and step parameters of the configurations in which V2 is at least an order of magnitude larger than 〈 V2 〉. To obtain more consistent data, ∼65 000 configurations of the (G:C)2 stack were built using systematic screening of the step parameters shift, slide, and twist. We show that undertwisted structures (twist<20°) are of special interest, because the π stack conformations with strong electronic couplings are found for a wide range of slide and shift. Although effective hole transfer can also occur in configurations with twist=30° and 35°, large mutual displacements of neighboring base pairs are required for that. Overtwisted conformation (twist38°) seems to be of limited interest in the context of effective hole transfer. The results may be helpful in the search for DNA based elements for nanoelectronics

Castes, Social Mobility and Politics in Goa

While the colonial policies and the missionary activities dented the caste system by playing upon the caste rivalries to divide and rule, the post-independence Indian democracy transformed the traditional castes into valuable vote-banks that have permitted non-brahmin castes to achieve political leadership in several States, particularly following the politics of reservation recommended by the Mandal Commission in 1980s.

Collaboration between infection control and occupational health in three continents: a success story with international impact

Globalization has been accompanied by the rapid spread of infectious diseases, and further strain on working conditions for health workers globally. Post-SARS, Canadian occupational health and infection control researchers got together to study how to better protect health workers, and found that training was indeed perceived as key to a positive safety culture. This led to developing information and communication technology (ICT) tools. The research conducted also showed the need for better workplace inspections, so a workplace audit tool was also developed to supplement worker questionnaires and the ICT. When invited to join Ecuadorean colleagues to promote occupational health and infection control, these tools were collectively adapted and improved, including face-to-face as well as on-line problem-based learning scenarios. The South African government then invited the team to work with local colleagues to improve occupational health and infection control, resulting in an improved web-based health information system to track incidents, exposures, and occupational injury and diseases. As the H1N1 pandemic struck, the online infection control course was adapted and translated into Spanish, as was a novel skill-building learning tool that permits health workers to practice selecting personal protective equipment. This tool was originally developed in collaboration with the countries from the Caribbean region and the Pan American Health Organization (PAHO). Research from these experiences led to strengthened focus on building capacity of health and safety committees, and new modules are thus being created, informed by that work. The products developed have been widely heralded as innovative and interactive, leading to their inclusion into “toolkits” used internationally. The tools used in Canada were substantially improved from the collaborative adaptation process for South and Central America and South Africa. This international collaboration between occupational health and infection control researchers led to the improvement of the research framework and development of tools, guidelines and information systems. Furthermore, the research and knowledge-transfer experience highlighted the value of partnership amongst Northern and Southern researchers in terms of sharing resources, experiences and knowledge.
