Síndrome Respiratorio Agudo Severo (SRAS): Lecciones y Retos
Valero,Nereida; Larreal,Yraima; Mosquera,Jesús; Rincón,Enrique;
Investigación Clínica , 2005,
Abstract: after four months of silence before a new incursion of severe acute respiratory syndrome virus (sars), world wide investigators specially from asia had have to face a coronavirus capable of great spreading and inducing high morbidity. the source and the capacity of this virus to associate with other opportunist microorganisms to induce progression of the disease, remain unclear. the comparison of the genomic sequence of different strains has generated discrepancies as for if the sars epidemic arose as an unique outbreak or it was produced for more than one genotype. however, this fact is secondary to the imminent threat that was controlled in august of 2003, after affecting 8.422 individuals, but before which we should be remain alert, since it is clear that the end of the sars is not yet here; and that the appearance of a single case can mean the beginning of a new wave, joining the outbreak of other diseases such as the avian flu. in this regard, it is very important to know the epidemic bases of morbid-mortality of sars and to keep a world wide surveillance in order to detect possible further cases.
Síndrome Respiratorio Agudo Severo (SRAS): Lecciones y Retos Severe Acute Respiratory Syndrome (SARS): Lesson and challenges

Abstract: Después de varios meses de silencio, ante una nueva incursión del virus causante del Síndrome Respiratorio Agudo Severo (SRAS), investigadores en todo el mundo y especialmente asiáticos se enfrentan a un coronavirus que ha demostrado gran transmisibilidad y morbilidad y que constituye una gran incógnita en cuanto a origen y asociación con otros patógenos que actuando como oportunistas puedan agravar la progresión de la enfermedad. La comparación de la secuencia genómica de distintas cepas ha generado discrepancias en cuanto a si la epidemia de SRAS surgió como un brote único o fue producida por más de un genotipo; sin embargo este hecho es secundario ante la inminente amenaza que fue controlada en agosto de 2003 después de afectar a 8.422 individuos pero ante la cual se debe permanecer alerta, dado que está claro que no se ha marcado el fin del SRAS y que la aparición de un solo caso puede significar el comienzo de una nueva oleada, aunado a la aparición de otras enfermedades como la influenza aviaria. De allí la importancia de conocer las bases epidemiológicas sobre las cuales se ha establecido la morbi-mortalidad de esta afección y asegurar la persistencia de la vigilancia mundial en el futuro, hecho crucial para detectar a tiempo posibles casos y por ende controlar su diseminación.

Manipulación mediática, identidad juvenil y prostitución de un bien necesario
Mosquera,Alexander;
Enlace , 2007,
Abstract: mobile telephony is something that identifies the current young. this is a new technology that is present in all fields of both public and private life, and whose presence can be felt across the ?ring-tones? multiplicity. this paper describes the relation between mass-media manipulation across the advertising discourse about cell phones, the youthful identity construction and the prostitution of an ancient necessary possession like the telephone. a corpus of some advertising announcements that appeared on venezuelan newspapers el nacional, la verdad and panorama during august 2005 was analyzed, from a theoretical-methodological gonzález de avila critical semiotics and lotman semiotics of culture perspective. also, magari?os de morentin?s contributions about the advertising messages, as well caro almela, bourdieu, pasquali, and eco?s contributions about mass-media. the results show a mass-media manipulation across the advertising discourse. this manipulation is focused on creating an urgent necessity to own a cell phone, because this is the sign-goods that identify the current young. as a preliminary conclusion, it can be said that the non-possession of a cell phone makes young people appear as ?excluded? from that mobile telephony world.
La semiótica de Lotman como teoría del conocimiento
Mosquera,Alexander;
Enlace , 2009,
Abstract: iuri mijailovich lotman (1922-1993) was an investigator of tartu university (estonia) with a recognized international trajectory, whose contributions in the field of the semiotics of culture extended the borders of the then so called soviet union, in spite of the difficulties and censorships imposed by the communist government to the diffusion of their work. according to caceres sanchez (in lotman, 1996), this work included a whole diversity of problems beyond the semiotics theory, to enter itself in mythology, cinema, history of culture, aesthetic one, theater, literature, among others. the present theoretical reflection tries to add a value more to the lotman contributions, when examining his text la semiosfera ii. semiótica de la cultura, del texto, de la conducta y del espacio (1998) and showing them as the bases to construct a knowledge theory.
La confrontación Colombia-Venezuela desde la perspectiva del análisis del discurso
Mosquera,Alexander;
Opción , 2006,
Abstract: many news broadcasts reflected the tension of the recent colombia-venezuela crisis, which occurred due to the capture in 2004 of a farc guerilla fighter in caracas (rodrigo granda). this paper is a preliminary advance on a research project, the objectives of which are to: 1) describe the implicit discourse of those announcements; 2) identify the semantic and pragmatic aspects of that discursive confrontation; 3) delineate the ideological components of those communications. some methodological and theoretical elements from colle (2000), bolívar (1998) and molero de cabeza (1985) were taken for the analysis. as preliminary conclusions, it can be said that in the granda affair colombia applied the old ?purposes justify the means? policy, and it questioned venezuela?s performance in the fight against terrorism, perhaps due to its close relationship with the u.s. government.

Advances in Geosciences (ADGEO) , 2008,
Abstract: The response of the equatorial and South American coastal ocean circulation to the anomalous March 2002 wind jet extending from the Gulf of Panama to 6° S is studied in a linear ocean model. Two experiments were performed: one without continental boundaries and the other with an eastern boundary at 81° W, representing the American continent. The spatial and temporal structure of the imposed wind anomaly, represented with idealized mathematical functions, is similar to that of the real jet. The duration of the wind jet was six days where the maximum intensity occurred at the third day. The results of the experiments indicate that the wind-jet anomaly over the Gulf of Panama is another source of ocean waves that influence the western coast of South America in the form of coastal Kelvin waves (CKW).
Cultivos transgénicos: una mirada desde la economía Transgenic cultures: from the economic viewpoint
Mosquera Mauricio
Revista Colombiana de Biotecnología , 2001,
Abstract: La introducción de semillas transgénicas en la actividad agrícola plantea una modificación a la función de producción de la misma, debido a la potencialidad de alcanzar características deseadas tales como mayores rendimientos, lo cual resulta fundamental en un entorno económico caracterizado por la libre competencia. Sin embargo, la aceptación de los productos de la ingeniería genética dista mucho de ser un proceso sencillo; en efecto, se ponen sobre el tapete discusiones relativas a la predominancia de los intereses del sector privado, del monopolio del conocimiento y de la seguridad de estos alimentos. Este artículo presenta los principales puntos de debate en torno a la adopción de los cultivos transgé-nicos y contribuye a la discusión sobre este tópico para Colombia. The introduction of transgenic seeds for agricultural purposes poses modification to their production, due to the potential for reaching desired characteristics such as greater yield, this being fundamental in an economic environment characterised by open market conditions. However, acceptance of products resulting from genetic engineering is far from becoming a simple process; discussion relating to the predominance of private sector interests, the monopoly of knowledge and the safety of such seeds/food is currently in the spotlight. This article presents the main points of debate regarding adoption of transgenic cultures, contributing to discussion about this topic for Colombia.
Lecturas críticas de los talleres de salud sexual y reproductiva y de fortalecimiento cultural desarrollados con mujeres negras desterradas por el conflicto armado en Colombia
Claudia Mosquera
Revista de Estudios Sociales , 2007,
Abstract: This article analyzes the speeches and social practices of government social practitioners - social workers and psychologists - who work in pro- grams that provide psychosocial care for displaced black women who come to Bogotá from the Pacific region as result of the country's internal armed conflict. The article focuses on the assumptions underlying two types of workshops that these programs offer: sexual and reproductive health, and cultural strengthening. It then shows how the speeches and practices used in these workshops illustrate two contradictory ways of valuing the black ethnic-racial presence in the country. Instead of being spaces of equity and justice, these workshops reproduce images and social representations of this "otherness" and create social distances that promote asymmetries in ethnic-racial relations with black people.
