El Mapocho Talagantino: proyectos de ayer y necesidades de hoy. /The Mapocho river in Talagante: yesterday projects and new necessities
María Isabel Pavez Reyes,Diego Vallejos Oberg
Revista de Urbanismo , 2010, DOI: doi: 10.5354/0717-5051.2010.6278
Abstract: El objetivo de este escrito es dar cuenta de la situación general del borde del río Mapocho en su paso por Talagante, tanto desde los proyectos habidos, como desde la realidad actual en el marco de un nuevo objetivo de desarrollo local asociado al turismo. Se se ala algunos problemas y desafíos a superar en lo referido a valorar el potencial paisajístico global y a generar proyectos desde la ordenación territorial, considerando, por tanto, no sólo las necesidades de la población actual y esperada de Talagante y Santiago, sino también las del mismo corredor fluvial./ This paper shows the historical treatment of the Mapocho river in Talagante, near Santiago, in the perspective of a new local development focused on turism. The autors indicates problems and opportunities of the actual use of the river side, with consequences involving Talagante and all the river.
Productivity and Efficiency in the Development of the Swedish Construction Sector  [PDF]
Anne Landin, Mats Oberg
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.46038
Abstract:

The measurement of productivity and efficiency of activities in the Swedish construction sector is examined. Understanding past and present levels of productivity is necessary to steer emerging and future developments aimed at increasing efficiency of construction. The absence of purposeful measurement methods and tools for determining current and targeted levels of productivity creates confusion for clients, designers, constructors and end-users, who are unable to make confident forecasts of costs and revenues or benefits over project life cycles. The findings of an investigation using panels of expert practitioners guided by senior researchers revealed shortcomings in the understanding of factors of driving productivity as well as uncertainty over where improvements might be achieved. The significance of the findings is that methods and tools must be calibrated to current and emerging construction practices and their technical bases rather than continuing with measurements that were conceived for earlier processes and products. The paper concludes with an outline of further research aimed at improving self-learning in regard to both process and product as part of a broad response to raising efficiency through innovation.

LIBYA – WHAT SHOULD HAVE BEEN DONE?
Jan OBERG
Bezbednosni Dijalozi , 2011,
Abstract: This article comes in three parts. First, what decision-makers could have learned about conflict-management in the light of the major conflicts the last few decades, beginning if you like with the lessons learned from (mis)handling the Balkans. Secondly, the author argues that a series of initiatives could - and should - have been tried and found in vain before taking to the NATO bombing campaign in the name of protecting the Libyan people. It also disputes the stated motives of that decision even though it had a mandate from the UN Security Council. The third part makes up a status as of August 15, 2011; a series of facts are presented that have not been featured prominently in the Western mainstream media, including the fact that over 15% of the Libyan people have become refugees which indicates a deficient protection. Next it makes 9 predictions about the future of Libya andargues that the NATO bombings may well be the starting point of a prolonged and complex violent conflict. The article ends with some reflections - pertaining to Scandinavia but other too - on whether war has become "Salongf hig" with both the Right and the Left; it is thefirst time in the history of Denmark, Sweden and Norway that their parliament votes "yes" to NATO's intervention with one little xenophobic party in Sweden as the only exception. In summary, although the author is strongly critical of this case of conflict-handling, the main thrust is the article is the constructive perspective - and thus the title - that it could have been handled with much less violence had the knowledge, the tools, the interests and the political will been present.
Semiclassical approach to fidelity amplitude
Ignacio García-Mata,Raúl O. Vallejos,Diego A. Wisniacki
Physics , 2011, DOI: 10.1088/1367-2630/13/10/103040
Abstract: The fidelity amplitude is a quantity of paramount importance in echo type experiments. We use semiclassical theory to study the average fidelity amplitude for quantum chaotic systems under external perturbation. We explain analytically two extreme cases: the random dynamics limit --attained approximately by strongly chaotic systems-- and the random perturbation limit, which shows a Lyapunov decay. Numerical simulations help us bridge the gap between both extreme cases.
Rol de la Nefrología en la pandemia por Influenza A (H1N1): Puesta al día
Vallejos,A.;
Nefrología (Madrid) , 2009,
Abstract: in june 2009, who declared pandemic swine origin influenza a virus (h1n1). since then, nephrologists were involved in several of our activities. decreased work attendance of healthcare for chronic renal patients. appeared new cases of acute renal failure associated with viral infection, mostly in young adults, with high mortality rate. there were infections in renal transplant patients and temporarily decreased the organs procurement in the weeks of further spread. scientific institutions were mobilized to agree on protocols for assessment and treatment in order to lessen the impact of the pandemic in renal patients.
Reacciones adversas por antibióticos en una unidad de cuidado intensivo pediátrico y neonatal de Bogotá
Vallejos,Alvaro;
Biomédica , 2007,
Abstract: introduction. critical care patients have a high probability of presenting adverse drugs reactions because the polytherapy that they receive usually include schemes with two or more antibiotics. most antibiotics have high toxicity risk, which can be potentialized when being associated with other drugs. objective. adverse reactions were detected and described in patients treated with antibiotics in a pediatric and neonatal intensive care. materials and methods. a follow up, descriptive and observational study of a cohort was made without control group. a daily follow-up was administered for a three month period for each patient. causality was evaluated on the basis of the naranjo scale. results. eighty-five patients were included in the study, 36.5% from the neonatal intensive care unit and 63.5% from the pediatric clinic. of twenty-seven antimicrobial medications administered, 97 adverse reactions were detected for 15 of these, in 37 patients (20 newborn and 17 older children). they were classified as mild (65%), moderate (35%) and serious (0). according to scale of naranjo, 68% were possible, 32% probable, and defined, none. based on laboratory test results, renal toxicity was detected in 38.1%, hematotoxicity in 24.7%,electrolytic abnormalities in 21.6% and hepatotoxicity in 15.5%. the distribution of adverse antibiotic reactions was as follows: gentamycine 20.6%, vancomycin 17.5%, amikacine 16.5%, ceftriaxone 15.5% and piperaciline tazobactam 13.4%. conclusions. the proportion of adverse reactions was of 43.7%. 55.6% of antibiotics produced adverse reactions. a program of institutional pharmacovigilance coordinated by a medical pharmacologist or pharmaceutical chemist was recommended by these data.
Conflictos socioambientales en la periferia de la modernidad: Apuntes para la intervención en contextos locales
Vallejos,Arturo;
Revista de Ciencias Sociales , 2008,
Abstract: this paper proposes to contribute to intervention in socio-environmental conflicts that have occurred in chile and latin america. in its general structure, the proposal tries to state the empirical evidence, that is, the context and pressure regarding natural resources that end in conflicts, such as the current proposal for intervention to resolve socio-environmental conflicts. later, the study introduces some theoretical suppositions from the social systems theory of niklas luhmann that should be taken into account for the intervention, and which will help to clarify a possible kind of intervention that takes into account the form and type of operation of the society where the socio-environmental conflict occurs.

Biomédica , 2010,
Abstract: Introducción. Los pacientes críticos tienen alta probabilidad de presentar reacciones adversas a los medicamentos por la politerapia farmacológica que reciben, pues incluye esquemas con dos o más antibióticos. La mayoría de antibióticos tienen alto riesgo de toxicidad, que puede potencializarse al asociarse con otros medicamentos. Objetivo. Detectar y describir las reacciones adversas por antibióticos en pacientes de cuidado intensivo pediátrico y neonatal. Materiales y métodos. Se realizó un estudio observacional descriptivo de seguimiento de una cohorte sin grupo de control con seguimiento diario durante tres meses de los pacientes. Se evaluó causalidad con la escala de Naranjo. Resultados. Se incluyeron 85 pacientes en el estudio, 36,5% en cuidado intensivo neonatal y 63,5% en pediátrico. Se administraron 27 antibióticos y se detectaron 97 reacciones adversas para 15 de estos en 37 pacientes (20 neonatos y 17 ni os mayores). Se clasificaron como leves el 65%, moderadas, 35% y ninguna como grave. Según la escala de Naranjo, 68% fueron posibles, 32%, probables y no hubo definidas. Por exámenes paraclínicos se detectó nefrotoxicidad en 38,1%, hematotoxicidad en 24,7%, alteraciones electrolíticas en 21,6% y hepatotoxicidad en 15,5%. La distribución de reacciones adversas fue de 20,6% para gentamicina, 17,5% para vancomicina, 16,5% para amikacina, 15,5% para ceftriaxona y 13,4% para piperacilina tazobactam. Conclusiones. La proporción de reacciones adversas fue de 43,7%. El 55,6% de los antibióticos ocasionó reacciones adversas. Es necesario un programa de farmacovigilancia institucional coordinado por médicos fármacólogos o químicos farmacéuticos. Introduction.
