Las negociaciones para el Tratado de Libre Comercio entre los países andinos y los Estados Unidos: reflexiones para el debate (Tema Central)

Este artículo presenta un análisis de las ventajas y desventajas que traería consigo la firma de un TLC andino con Estados Unidos. A partir del acercamiento a diferentes sectores de la economía andina, el autor determina quienes podrían ser los posibles perdedores y ganadores con la firma de un Tratado de este tipo. La inexistencia de una agenda productiva interna en cada uno de los países, es señalada como una de las principales desventajas que tienen los andinos para poder aprovechar las ventajas que representaría la firma de un TLC y para poder convertir en oportunidades las exigencias que el mismo plantea. El desarrollo de un debate sustentado en criterios técnicos y políticos, más allá de fundamentos ideológicos, es para el autor el elemento central del cual se debe partir para determinar la conveniencia del TLC.

La Ley de Preferencias Arancelarias Andinas y el Proceso ALCA (Tema Central)

El autor analiza la Ley de Preferencias Arancelarias Andinas como política unilateral concedida por EE.UU. a países andinos (excepto Venezuela) dirigidas a promover las exportaciones andinas a mercados estadounidenses y la sustitución de cultivos ilícitos. El artículo explora las implicaciones de esta ley, y contrapone varios enfoques sobre su efectividad, unos en el sentido de que la ATPA no ha tenido una incidencia significativa en la modificación de la producción o la estructura exportadora de las naciones beneficiarias, y otros que mencionan que esta ley sí ha promovido importantes flujos de inversión entre EE.UU. y los países andinos.

Simón Rodríguez: un pensamiento americano (Dossier: Bicentenario, rastros y revelaciones de la Independencia)

El autor sostiene que Simón Rodríguez se propuso crear un pensamiento americano, que conociera y llegara a resolver los problemas de la región. Estos últimos tenían que ver con la vida social, las instituciones, las conductas e ideas, las perspectivas del pasado y del futuro. Era importante crear una conciencia del “ser social” en América por medio de la Razón, y no basarse en proyectos civilizatorios inspirados en ideas importadas y en la política del exterminio, como los de Andrés Bello y Faustino Sarmiento. Guzmán enfatiza que Rodríguez fue defensor de la república, inspirado en la Revolución francesa y en las utopías sociales europeas, que sus ideas pedagógicas planteaban una instrucción social general, basada en la Razón que proviene del estudio de las cosas, y en una valoración por el trabajo útil. El autor resalta dos nociones de Rodríguez: que sin luces, no habría proyectos propios y los políticos estarían condenados a imitar, y que la realidad podía cambiarse con la unión, el desarrollo de las industrias y el derecho de propiedad, junto a la enseñanza de oficios útiles.

Land-cover classification from airborne LIDAR data fused with aerial optical images

Airborne LIght Detection And Ranging (LIDAR) provides accurate height information for objects on the earth, which makes LIDAR become more and more popular in terrain and land surveying. In particular, LIDAR data offer vital and significant features for land-cover classification which is an important task in many application domains. In this paper, an unsupervised approach based on an improved fuzzy Markov random field (FMRF) model is developed, by which the LIDAR data, its co-registered images acquired by optical sensors, i.e. aerial color image and near infrared image, and other derived features are fused effectively to improve the ability of the LIDAR system for the accurate land-cover classification. In the proposed FMRF model-based approach, the spatial contextual information is applied by modeling the image as a Markov random field (MRF), with which the fuzzy logic is introduced simultaneously to reduce the errors caused by the hard classification. Moreover, a Lagrange-Multiplier (LM) algorithm is employed to calculate a maximum A posteriori (MAP) estimate for the classification. The experimental results have proved that fusing the height data and optical images is particularly suited for the land-cover classification. The proposed approach works very well for the classification from airborne LIDAR data fused with its coregistered optical images and the average accuracy is improved to 88.9%.

Perfil motivacional da geração Y comparado ao de outros grupos etários: investigação em uma instituição financeira nacional

A presente dissertação investiga o perfil motivacional de empregados de uma grande instituição financeira brasileira, inseridos no corte demográfico designado de “Geração Y” (Y’s). Tal perfil foi comparado ao de empregados pertencentes a outros grupos etários da mesma instituição. Para dar suporte à pesquisa, o referencial teórico analisa os cortes geracionais – com enfoque na Geração Y – e diferentes visões sobre o tema da motivação, bem como debate a importância do conhecimento do perfil motivacional desses empregados, para uma adequada formulação de estratégias de motivação laboral. Secundariamente, para essa análise a pesquisa busca auxílio na teoria do contrato psicológico de trabalho. Na coleta de dados da pesquisa foi utilizada a Escala de Valores de Schwartz (Schwartz Value Survey), em sua versão PVQ – Portrait Value Questionnaire, com o objetivo de prescrutar os tipos motivacionais mais relevantes dos Y’s e seus cohorts, permitindo-se, com isso, traçar um perfil motivacional de cada grupo demográfico. Com base na amostra coletada, o estudo conclui que não há evidência sobre a existência de diferenças no perfil motivacional, sob o ponto de vista estatístico, entre os cortes geracionais dentro da organização pesquisada.

Folkcomunicación ciudadana a partir de la web 2.0 y de la movilidad

The social media are increasingly present in the lives of citizens, especially when the intention is to share views and information among its communities. However, that is something that leaves the control of citizens near the cluster communication, and reinforce construction of public opinion. This paper presents, from a conceptual discussion and case study grounds to believe that contemporary citizens are the true owners of the fourth estate.

An in vitro comparison of subjective image quality of panoramic views acquired via 2D or 3D imaging

Objectives: The objective of this study is to compare subjective image quality and diagnostic validity of cone-beam CT (CBCT) panoramic reformatting with digital panoramic radiographs. Materials and methods: Four dry human skulls and two formalin-fixed human heads were scanned using nine different CBCTs, one multi-slice CT (MSCT) and one standard digital panoramic device. Panoramic views were generated from CBCTs in four slice thicknesses. Seven observers scored image quality and visibility of 14 anatomical structures. Four observers repeated the observation after 4 weeks. Results: Digital panoramic radiographs showed significantly better visualization of anatomical structures except for the condyle. Statistical analysis of image quality showed that the 3D imaging modalities (CBCTs and MSCT) were 7.3 times more likely to receive poor scores than the 2D modality. Yet, image quality from NewTom VGi® and 3D Accuitomo 170® was almost equivalent to that of digital panoramic radiographs with respective odds ratio estimates of 1.2 and 1.6 at 95% Wald confidence limits. A substantial overall agreement amongst observers was found. Intra-observer agreement was moderate to substantial. Conclusions: While 2D-panoramic images are significantly better for subjective diagnosis, 2/3 of the 3D-reformatted panoramic images are moderate or good for diagnostic purposes. Clinical relevance: Panoramic reformattings from particular CBCTs are comparable to digital panoramic images concerning the overall image quality and visualization of anatomical structures. This clinically implies that a 3D-derived panoramic view can be generated for diagnosis with a recommended 20-mm slice thickness, if CBCT data is a priori available for other purposes.
