La guerra contra las drogas es contraproducente: un análisis económico de edquilibrio general
Carlos Ortiz
Lecturas de Economía , 2002,
Abstract: La represión de la oferta de drogas ilícitas es anlizada en un contexto de equilibrio general. Los riesgos de la actividad productora de drogas son explícitamente considerados y las drogas son pensadas como bienes básicos. El modelo estático arroja que la represión de la oferta de drogas amplifica la ofera incrementando su rentabilidad. Adicionalmente, en un contexto de economía abierta la mayor demanda del mercado mundial induce una mayor especialización del país productor de drotas. Finalmente, una versión dinámica del modelo arroja que la represión de la oferta de drogas disminuye la tasa de crecimiento económico tanto en el corto como en el largo plazo. Por consiguiente, estos modelos predicen que la represión de la oferta de drogas ilícitas no es sólo inútil sino también contraproducente.
Compa ías militares privadas: hacia la transformación del estado y la nueva gerencia pública de la seguridad.
Carlos ORTIZ
Relaciones Internacionales , 2008,
Abstract: Las compa ías militares privadas (CMPs) han generado muchas inquietudes en el público debido a su notoria participación en los conflictos de Afganistán e Irak. La amplia cobertura de sus actividades en los medios de comunicación ha contribuido a presentarlos como un nuevo fenómeno. Sin embargo, su surgimiento y proliferación se dan durante décadas de un proceso de transformación del estado y penetración gradual de su monopolio sobre el uso legítimo de la fuerza. Este artículo discute que la Nueva Gerencia Pública ha enlazado dinámicas históricas importantes de una manera que ayuda a explicar la continua legitimación y expansión del mercado de los servicios militares privados en el nuevo milenio. Se espera que el enfoque técnico del artículo contribuya a la apertura de un debate constructivo, ya que las tendencias actuales apuntan a la expansión de las actividades de las compa ías militares privadas en el mercado hispano parlante. The involvement of Private Military Companies (PMCs) in the conflicts in Afghanistan and Iraq has engendered many concerns in the public. Although the wide coverage of their activities by the news media has contributed to present PMCs anew, their proliferation builds on decades of state transformation and the gradual penetration of the state monopoly of violence by private actors. This article argues that New Public Management has enmeshed historical dynamics in a way that helps explaining the apparently novel nature of the phenomenon and the broader consolidation of the market for private military services in the twenty-first century. It is hoped that the technical nature of the argument will contribute to open up a constructive debate at a time when unfolding trends suggest an expansion of the activities of PMCs in Latin America and beyond.
Uniform Versions of Infinitary Properties in Banach Spaces
Carlos Ortiz
Mathematics , 1999,
Abstract: In functional analysis it is of interest to study the following general question: Is the uniform version of a property that holds in all Banach spaces also valid in all Banach spaces? Examples of affirmative answers to the above question are the host of proofs of almost-isometric versions of well known isometric theorems. Another example is Rosenthal's uniform version of Krivine's Theorem. Using an extended version of Henson's Compactness result for positive bounded formulas in normed structures, we show that the answer of the above question is in fact yes for every property that can be expressed in a particular infinitary language.
A Model Existence Theorem for Infinitary Formulas in Metric Spaces
Carlos Ortiz
Mathematics , 1998,
Abstract: We prove a Model Existence Theorem for a fully infinitary logic for metric structures. This result is based on a generalization of the notions of approximate formulas and approximate truth in normed structures introduced by Henson and studied in different forms by Anderson and Fajardo & Keisler. This theorem extends Henson's Compactness Theorem for approximate truth in normed space structures to infinitary formulas.
La idealización del amor y la mujer en La vorágine
Ortiz Caraballo,Carlos Daniel;
Folios , 2008,
Abstract: this essay is a sociocritic analysis of the novel la vorágine (1924), written by josé eustasio rivera (neiva, 1888-new york, 1928). its objective is to elucidate one of the existent axiological position presented in this literary work, specifically, the romantic one (girard, 1963). the reading of the text is organized in two parts: first, the idealization of love, where it is established the construction of the romantic position taken in terms of love, the socioeconomic values of modernity and capitalism, taking into account the hero of the novel and the idealization of a woman, according to the women characters and their ideological voice.
The War on Drugs is Counterproductive, Once Again
Ortiz,Carlos Humberto;
Lecturas de Economía , 2009,
Abstract: a two-sector general equilibrium model that included drugs as basic goods was relatively successful at explaining the waste of resources that the war on drugs incurs (ortiz, 2003). due to the assumption of constant productivity, the model predicted the rise of the drug price with supply repression. yet plan colombia, an unparalleled effort to eradicate drug production in colombia, had no significant effect on drug prices. in order to correct the model two sources of productivity improvement in the drugs sector are examined. the modified model helps to understand why drug prices have remained stable, why global supply and demand have not diminished, and why coca plantations were spread throughout the nation under plan colombia.
Crisis y evolución actual de la epistemología
Moreno Ortiz,Juan Carlos;
Co-herencia , 2008,
Abstract: it is not easy to reflect upon epistemology today, for three special reasons: because the crisis which has taken place in epistemology, defined as something specifically modern; because of its ever more tangled and disguised relationship with fields like cognitive theory and philosophy of science, among others; and because of its increasing naturalization. epistemology has stopped being the a priori normative and universal reflection, pretending to establish the essential conditions of rationality, in order to evolve towards a critical and plural reflection, whose normative function consists on offering operating and pragmatic criteria to reconcile the advances of knowledge. this article synthesizes the changes operated on contemporary epistemology and identifies new ways of reflecting about regulation and knowledge, other than the epistemological proposals developed in modernity.
APRENDIZAJE EN LA PRODUCCIóN DE CAPITAL, CRECIMIENTO ACELERADO Y CAMBIO ESTRUCTURAL
Ortiz,Carlos Humberto;
Cuadernos de Economía , 2008,
Abstract: based on a two-sector model of endogenous growth (rebelo 1991), where a consumption good and a capital good are produced, this paper analyzes the effect of assuming learning-by-doing in the capital-good sector. the modified model reproduces two patterns of long-run economic development: accelerated growth and structural change.
LUCHANDO INFRUCTUOSAMENTE CONTRA LA HIDRA: UN MODELO SENCILLO DEL NARCOTRáFICO
Ortiz,Carlos Humberto;
Cuadernos de Economía , 2002,
Abstract: a simple model of drug trafficking, which embodies this activity risks, is shown in this paper. the model helps to explain two stylized facts of this activity: the generation of extraordinary profits and strong reproduction ability under prohibition and repression. the model creates a direct link between the repression of supply, which has been the dominant strategy in the fight against drug trafficking, and the mentioned facts.
Realidad aumentada en medicina
Ortiz Rangel,Carlos Enrique;
Revista Colombiana de Cardiología , 2011,
Abstract: nowadays, augmented reality represents a new form of visualization that combines virtuality with reality in a functional way, creating new possibilities for the interpretation of information that was not previously available. these possibilities lead to new ways of learning and acknowledging data, to process them into information and to convert them into knowledge easily. various ways to carry out experiments in augmented reality are available from different computing and telecommunications platforms, which facilitate the fast and economic development of projects. medicine, and cardiology in particular, can take advantage of this new type of media to complement the information yet available, transforming it into other formats and passing them to three dimensions, wherever these images are an appropriate complement.
