Manzini,Jorge Luis;
Acta bioethica , 2005, DOI: 10.4067/S1726-569X2005000200009
Abstract: this paper pretends to draw a brief review upon the ethical aspects of a prescription at a "micro" level, that is of the therapeutic relationship based on the georgetown "theory of principles" and on the technical aspects of a correct prescription according to the lex artis, sustained on the so-called "evidence based medicine" and on the who's requests and publications. it then turns to the subject of the medical prescription as a problem of public health. it stops at its social impact and at the undue pressures that doctors must suffer in order to prescribe, especially those coming from the pharmaceutical industry. it also offers a juridical framework focused on the human rights' international law. universal access to medication should be reached -understood as a social good of fundamental importance- in order to attain the right to sanitary assistance. several ethical justifications that hold up this right are taken into account, especially rawls' theory of justice

Abstract: this paper consists in a particularised analysis of the declaration of helsinki, revised at the 52nd wma general assembly at edinburgh in october 2000. the framework was as follows: 1) an introduction to the subject 2) a general consideration about formal and substantial aspects of the changes 3) a detailed analysis of every modified article, be it a change or an addition; and the comparison, when appropiate, between the spanish and the english versions of the declaration. this plan was developed by means of xxv "commentaries" interpolated along the transcription of the declaration, as was available from the wma website, http://www.wma.net/s/helsinki.html, on november 28, 2000. the phrases and paragraphs analysed are identified by means of different printing characters for the modified and new pieces, and the english version. the analysis was made from a bioethical perspective, especially regarding human rights concerns, as well as considering the scientific issues of medical research, including the viewpoint of evidence based medicine. conclusions: 1) all of the amendments strengthen the declaration, advocating for higher respect for the human rights of research subjects. 2) a further revision of the formal aspects (language) of the spanish version would be advisable, because of its many punctual weaknesses and ambiguities, as compared with the english version

Abstract: Este artículo hace una sucinta revisión de los aspectos éticos de la prescripción a nivel "micro", el de la relación terapéutica, con fundamento en la "teoría de los principios" (de Georgetown), y en los aspectos técnicos de la correcta prescripción según la lex artis, sustentada en la denominada "medicina basada en la evidencia" y en las recomendaciones y publicaciones de la OMS. Luego, se aborda el tema de la prescripción médica en tanto problema de salud pública. Se comenta su impacto social y las presiones indebidas que sufren los médicos para prescribir, especialmente por parte de la industria farmacéutica. Se provee a continuación un marco jurídico, centrado en el llamado Derecho Internacional de los Derechos Humanos. Se considera que podría lograrse el acceso universal a los medicamentos, entendidos como bien social, de fundamental importancia para efectivizar el Derecho a la Asistencia Sanitaria. Se revisan las distintas justificaciones éticas que sostienen este derecho, especialmente la teoría de la justicia de John Rawls Este texto se inicia como uma breve revis o dos aspectos éticos da prescri o em nível "micro", ou seja, a da rela o terapêutica, com fundamento na "teoria dos princípios (Georgetown)", e dos aspectos técnicos da correta prescri o segundo a lex artis, sustentada na denominada "medicina baseada em evidência", as recomenda es e publica es da OMS.

A Decision-Support System for the Car Pooling Problem  [PDF]
Riccardo Manzini, Arrigo Pareschi
Journal of Transportation Technologies (JTTs) , 2012, DOI: 10.4236/jtts.2012.22011
Abstract: The continuous increase of human mobility combined with a relevant use of private vehicles contributes to increase the ill effects of vehicle externalities on the environment, e.g. high levels of air pollution, toxic emissions, noise pollution, and on the quality of life, e.g. parking problem, traffic congestion, and increase in the number of crashes and accidents. Transport demand management plays a very critical role in achieving greenhouse gas emission reduction targets. This study demonstrates that car pooling (CP) is an effective strategy to reduce transport volumes, transportation costs and related hill externalities in agreement with EU programs of emissions reduction targets. This paper presents an original approach to solve the CP problem. It is based on hierarchical clustering models, which have been adopted by an original decision support system (DSS). The DSS helps mobility managers to generate the pools and to design feasible paths for shared vehicles. A significant case studies and obtained results by the application of the proposed models are illustrated. They demonstrate the effectiveness of the approach and the supporting decisions tool.
Lower bounds for sparse matrix vector multiplication on hypercubic networks
Giovanni Manzini
Discrete Mathematics & Theoretical Computer Science , 1998,
Abstract: In this paper we consider the problem of computing on a local memory machine the product y = Ax,where A is a random n×n sparse matrix with Θ(n) nonzero elements. To study the average case communication cost of this problem, we introduce four different probability measures on the set of sparse matrices. We prove that on most local memory machines with p processors, this computation requires Ω((n/p) log p) time on the average. We prove that the same lower bound also holds, in the worst case, for matrices with only 2n or 3n nonzero elements.
Tragedia humanitaria del desplazamiento forzado en Colombia
Garay Salamanca,Luis Jorge;
Estudios Políticos , 2009,
Abstract: this article presents a diagnosis of the situation of the population of displaced persons in colombia, from the results of the second national verification survey of the monitoring commission of public policies on forced displacement carried out in 2008. factors of vulnerability in the areas of health, education, food security, housing, informal labor, generation of incomes, among others, reveal a situation of extreme precariousness that is still far away from the effective enjoyment of rights on the part of populations in situations of forced displacement, which synthesizes the gravity of the humanitarian crisis from which the country suffers.

Mesoamérica o el Proyecto Mesoamérica: La historia como pretexto
Capdepont Ballina, Jorge Luis;
LiminaR , 2011,
Abstract: this work focuses on the analysis of the historical context related to the proyecto mesoamérica, questioning the official version that tries to bring down the economical rates indexes and social backwardness of the south -south-east of mexico and central america, when everything seems to indicate that it is one more of the attempts for taking advantage of the strategic location of the region and its valuable natural resources (forest, mineral and water), in benefit of the big world powers, especially the united states. the results obtained till now from the putting in march of the plan puebla-panamá, now proyecto mesoamérica, indicate that communications and transport infrastructure have improved in the area, but continues existing a high social and economic marginalization of the people; whereas the new strategies of the agreement appear towards a clear utilization and exploitation of the natural resources, more than to promoting the industrialization with technology of top and the own conservation of the environment.

Dolor agudo o episodico por cáncer
Yera Nadal,Jorge Luis;
Revista Cubana de Anestesiolog?-a y Reanimaci?3n , 2012,
Abstract: introduction: from the concept introduced by the international association for the study and treatment of pain, the terms acute, subacute, chronic and intermittent pain are considered and key in the course of pain in a cancer patient, as well as the elements related to pain pathophysiology. objectives: to identify the incidence and prevalence of episodical pain know as "breakthrough pain", the definitions of other authors, the clinical features and its control using opioids. development: it is refer to the pathophysiological features of cancer pain and the causes that could originate it in its interrelation with acute pain due to cancer. it is emphasized the role played by the osteoclastic and osteoblastic activity and the allogenic substances produced from the tumor stroma causing the incidental pain. authors analyzed the definitions of "breakthrough pain" mentioned by some authors. the use of opioids in the basal control of cancer pain and the usefulness of the new opioids of fast action are examined are the ideal treatment of episodical pain due to cancer how we define in spanish language to the term used in english language during years. conclusions: it is essential and important the appropriate use of the fentanyl formulas with a good titration of dose to be use.
