Este documento presenta el perfil sociodemográfico de la infancia y adolescencia en Haití y los principales desafíos a los que se enfrentan, analizando para cada sector —educación, seguridad alimentaria y nutrición, salud materna e infantil, protección de la infancia, inserción laboral y empleabilidad de las y los adolescentes— los desafíos específicos e ineludibles, así como los mecanismos de protección y promoción social vigentes. De acuerdo con los datos disponibles, se tratará de aplicar una parrilla temática con perspectiva de género, que incluye los marcos referenciales y los sistemas de información, los mecanismos en vigor, las fuentes y niveles de financiamiento.

En el año 2010, se creó la Red de los Sistemas Nacionales de Inversión Pública (Red SNIP), cuya misión principal es la de contribuir a mejorar la gestión de la inversión pública de los países miembros a través del intercambio de experiencias, documentos e información sobre evaluación y gestión de proyectos, sistemas de información y actividades de capacitación, entre otras tareas de cooperación. En este documento se presenta el resumen de las principales metodologías generales y sectoriales que se encuentran actualmente en vigencia en los países que forman parte de la Red SNIP.

Este documento se enfoca en la identificación de los retos económicos, sociales y ambientales del desarrollo rural y agroalimentario en Centroamérica y la República Dominicana, y la importancia de los sistemas de información para la formulación, monitoreo y evaluación de políticas públicas. Asimismo, se muestra la interconexión de dichos retos con los ODS y con las demás metas e indicadores sobre la seguridad alimentaria y nutricional y el desarrollo rural. En última instancia, se plantea la necesidad de fortalecer y perfeccionar la base de datos SIAGRO-GIPP —mediante recursos de asistencia y cooperación técnica domésticos e internacionales— para facilitar la interacción de la información con la generación de conocimiento, análisis y recomendaciones de políticas públicas para un desarrollo sostenible e incluyente de las sociedades centroamericanas, en particular, de sus zonas rurales.

The concept of ontoloy as a tool for knowledge organization and representation, which is not yet stable, is analyzed in two spanish journals of information science, namely “Scire: representación y organización del conocimiento” and “Ibersid: revista de sistemas de información y documentación”, both published by the University of Zaragoza. The term "ontology" and its variations were searched in the fields of title, keywords and abstract. A corpus of eighteen articles was obtained. The approaches to ontologies were classified into four categories of analysis: conceptualization, comparison, application and new applications. It was observed that the way which the concept of ontologies is treated in both periodicals is in consonance with their editorial policies. The term ontology is suffering a process of meta-terminologization, from the field of philosophy towards information science, a fact that deserves further and more vertical studies.

The misuse of land by man and is causing serious problems to the environment, resulting in ecological imbalance and depletion of natural resources, especially when it comes to areas of permanent preservation, that ecosystems are essential for balance and water conservation importance . Conflicts of land use is a major cause of silting of rivers and water bodies, causing significant losses in soil and decaying natural water resources both in quantity and in quality. Within this scenario, the planning becomes essential for the control of environmental impacts to the environment factor. This study aimed to evaluate land use conflicts in permanent preservation areas of the stream Água Fria watershed, Bofete (SP) using Geographic Information System and satellite image of LANDSAT - 5 of 2010, scale 1:50000. The results show that 51.16% of the permanent preservation areas of the watershed are conflicting, especially for pasture (88.94%) and reforestation with eucalyptus (11.06%). The GIS IDRISI Selva and Cartalinx along with GIS techniques demonstrated speed and efficiency in identifying, measuring and editing maps of land use, preservation and ongoing conflicts in areas of permanent preservation.

This study aims to perform the morphometric characterization of the watershed stream Petiço, Botucatu-SP, through techniques of GIS by GIS IDRISI Selva and Charter planialtimetric Botucatu (SF-22-ZB-VI-3) , edited by IBGE (1969), scale 1: 50000 for ranking the drainage network and the morphometric analysis. The variables analyzed were the dimensions, the relief pattern, pattern of the drainage network and the shape variables. The results show that related to how the watershed has an oblong shape with environmental interpretation with low tendency to flooding and erosion. The sinuosity index of 1.22 shows that the channels of the micro tend to be somewhat sinuous, which allows to infer that is permeable soil with good water infiltration. Based on the results of the morphometric variables was found that the watershed is in good condition of conservation, however, presents certain risks of susceptibility to erosion, and environmental degradation in some points, being fundamental to the maintenance of vegetation cover, in view of the roughness coefficient (Rn). Thus, the evaluation of morphometric characteristics in the study watershed constitutes an important tool in conjunction with the use of GIS and Geographic Information Systems makes possible the planning and management of natural resources aimed at their conservation.

The study aimed to obtain the land use of the watershed Stream São Caetano - Botucatu (SP), through the satellite image. The cartographic databases were: planialtimetric letter in digital format (IBGE) used in georeferencing, and satellite image. Geographic Information Systems (GIS) -IDRISI Selva was use to perform the image georeferencing and to do the final thematic map. In the software CAD - CartaLinx, it was performed the delimitation of the area under study (boundary, drainage network and areas of use and coverage). The land use of the watershed showed that pasture was the class which occupied most of the area, with 34.51% (1117,94 ha), the remainder of the area was urban (692,19ha), forests (809,79ha), cultures (599,96ha) and a very small part of reforestation (19,53ha). The use of remote sensing and geoprocessing were very satisfactory in the present work. Technologies must be increasingly used in agricultural and environmental studies, because technological tools, such as Geographic Information System (GIS), present speed, efficiency, reliable results, helping in increasing sustainability

The study aimed to obtain the land use of the watershed Ribeirão Santo Antonio - São Manuel (SP), through the thematic map of the satellite image. The cartographic databases were planialtimetric letter in digital format used in georeferencing and the satellite image. Geographic Information Systems (GIS) -IDRISI Andes 15.0 was use to perform the image georeferencing and to do the thematic map obtained from the visual interpretation the satellite image. The map of land use showed that the culture of sugar cane occupies most of the area (81.00%), when analyzing the satellite image. This result show us the predominance of agricultural occupation in the region. The thematic map obtained by the classification screen, using GIS, allowed the mapping of land use, generating data that will assist in future planning area recovery. The results of the study showed the efficiency, speed and reliability of the tools used, these being very useful for future projects.

A Informação Profissional, um dos componentes do processo de Orientação Profissional Vocacional ou para a Carreira, visa fornecer dados da realidade do mundo ocupacional de forma a auxiliar pessoas em processos de tomada de decisão. Este estudo objetiva sistematizar e analisar a produção do conhecimento sobre a temática Informação Profissional com base na revisão da literatura. Os dados foram organizados em três categorias, com base em Robinson e colaboradores: (1) modelos de recursos impressos, (2) programas e sistemas de informação e (3) sites na internet. Os resultados mostram que as novas Tecnologias da Informação e Comunicação (TICs) aliadas às estratégias tradicionais representam inúmeras oportunidades de desenvolvimento da Informação Profissional, com desafios e limites a serem enfrentados em um campo que não para de evoluir. O estudo evidencia o papel da Informação Profissional, com seus limites e possibilidades, no contexto brasileiro bem como nos países desenvolvidos.
