Quantifying the risk of coronary artery disease in a community: The Bambuí Project

OBJECTIVE: To determine the coronary risk profile in adults and elderly in a community. METHODS: The study comprised a sample of adults (30-59 years, n=547) and the entire elderly population (60-74 years, n=1165) residing in Bambuí town, Brazil. The Framingham score based on sex, age, smoking, diabetes mellitus, systolic and diastolic blood pressure, total cholesterol, and HDL-C was used. The score based on age and sex was defined as "expected" and compared with the mean score obtained by the sum of all risk factors in each age group and sex (score "observed"). RESULTS: The difference between the scores "observed" and "expected" increased with aging in both sexes. Smoking increased the difference from 30 years of age onwards, in both sexes, and hypertension was important in men above the age of 30 years and in women above the age of 50 years. Diabetes and elevated total cholesterol increased the risk of the disease above the age of 50 years in both sexes. A higher level of HDL-C reduced the risk among men above the age of 30 years, with no significant difference among women. Less schooling (< 4 years versus ³ 4 years) was associated with a higher score in adults of both sexes, but not among the elderly. CONCLUSION: Based on these results, in the community studied, the risk of coronary artery disease may be reduced up to 44% in men and 38% in women.

Educación de adolescentes y jóvenes: una mirada desde los procesos de diseño y gestión de políticas públicas en la educación secundaria obligatoria. El caso de las provincias de Buenos Aires, Córdoba y Entre Ríos, República Argentina (2010-2015).

El Sistema Educativo constituye un conjunto organizado de servicios y acciones educativas reguladas por el Estado que posibilitan el ejercicio del derecho a la educación. Por ello, le corresponde garantizar el acceso de niños, adolescentes, jóvenes y adultos a la información, el conocimiento y la diversidad de bienes culturales, claves para el desarrollo personal y social y la participación ciudadana. Este Proyecto centra su interés en un nivel educativo que por la multiplicidad, diversidad y multicausalidad de las problemáticas que lo atraviesan se constituye en uno de los más críticos y complejos del sistema: el Nivel Secundario. Se propone, entonces, analizar la configuración de la Educación Secundaria Obligatoria en las provincias de Buenos Aires, Córdoba y Entre Ríos -en el contexto nacional- durante el período 2010-2015, en relación con el diseño y gestión de políticas públicas; comprender los procesos de mejora, identificar las problemáticas prioritarias y contribuir a la generación de nuevas alternativas y posibilidades en los respectivos territorios. Las jurisdicciones seleccionadas han adoptado un conjunto de decisiones contextualizadas tendientes a expandir y mejorar el servicio que brindan las escuelas secundarias de sus respectivos territorios, en concordancia con lo dispuesto en la Ley de Educación Nacional N°26.206. A partir de la focalización de diversos aspectos (ofertas formativas, normativa, implementación, cobertura, trayectoria educativa; organización institucional, currículum y prácticas; organización formal del trabajo docente y desarrollo profesional), se realizará un estudio de corte exploratorio-descriptivo, de base cuanti-cualitativa focalizado en las provincias seleccionadas. Se entiende que una investigación de esta naturaleza podrá contribuir con el conocimiento y comprensión de los cambios implementados en estas jurisdicciones, colaborando en la mejora de los procesos en curso y en la prevención de efectos no deseados en aquellas que aún no han tomado la decisión de innovar. El equipo de investigación desarrollará un análisis detallado de la realidad de la Educación Secundaria Obligatoria, las problemáticas que presenta el Nivel y los retos que, para enfrentarlas, se han asumido desde distintas gestiones. Se pretende dar cuenta de lo que sucede, intentar algunas interpretaciones sobre por qué es así y aportar a la construcción de alternativas de acción, cuya materialización pudiera contribuir con los procesos de mejora.

Instrumentation and software for the VERITAS Project and the detection of TeV Gamma-Ray Emission from the BL Lacertae Object 1ES1959+650

Transmission of Cherenkov light through the atmosphere is strongly influenced by the optical clarity of the atmosphere and the prevailing weather conditions. The performance of telescopes measuring this light is therefore dependent on atmospheric effects. This thesis presents software and hardware developed to implement a prototype sky monitoring system for use on the proposed next-generation gamma-ray telescope array, VERITAS. The system, consisting of a CCD camera and a far-infrared pyrometer, was successfully installed and tested on the ten metre atmospheric Cherenkov imaging telescope operated by the VERITAS Collaboration at the F.L. Whipple Observatory in Arizona. The thesis also presents the results of observations of the BL Lacertae object, 1ES1959+650, made with the Whipple ten metre telescope. The observations provide evidence for TeV gamma-ray emission from the BL Lacertae object, 1ES1959+650, at a level of more than 15 standard deviations above background. This represents the first unequivocal detection of this object at TeV energies, making it only the third extragalactic source seen at such levels of significance in this energy range. The flux variability of the source on a number of timescales is also investigated.

RECERCAT. El Dipòsit de la Recerca de Catalunya

Seguint la tendència mundial de crear dipòsits institucionals d'accés lliure per recopilar i preservar els documents d'investigació generats en les institucions acadèmiques, el CESCA i el CBUC han posat en funcionament RECERCAT. RECERCAT és un dipòsit cooperatiu de documents digitals que inclou la literatura de recerca de les universitats i dels centres d'investigació de Catalunya, com ara articles encara no publicats (preprints), comunicacions a congressos, informes de recerca, working papers, projectes de final de carrera, memòries tècniques, etc. La comunicació pretén explicar els processos que s'han seguit per posar en marxa aquest projecte: des de la selecció i adaptació del programari amb el que funciona (DSpace), fins als treballs duts a terme per establir les polítiques d'accés, d’introducció de dades, de metadades Dublin Core necessàries per descriure els documents, el tipus de llicència de les Creative Commons sota la qual es troben subjectes els documents, etc.

Dipòsits col·lectius d'e-informació

El Centre de Supercomputació de Catalunya (CESCA) i el Consorci de Biblioteques Universitàries de Catalunya (CBUC) des del 1999, com a fruït del llavors Pla Estratègic Catalunya en Xarxa, promouen activitats per posar continguts a la xarxa en accés obert. Això s’ha materialitzat, de moment, en la posada en marxa de tres dipòsits col·lectius d'e-informació: Tesis Doctorals en Xarxa (TDX), Dipòsit de la Recerca de Catalunya (RECERCAT) i Revistes Catalanes amb Accés Obert (RACO). Al febrer de 2001 va néixer el TDX (www.tesisenxarxa.net), que permet la consulta de més de 3400 tesis doctorals llegides a les universitats de Catalunya i d'altres comunitats autònomes. Al setembre de 2005 es va inaugurar RECERCAT (www.recercat.net), un dipòsit cooperatiu de documents digitals que inclou la literatura de recerca de les universitats i dels centres d’investigació de Catalunya, com ara articles encara no publicats (preprints), comunicacions a congressos, informes de recerca, working papers, projectes de final de carrera, memòries tècniques, etc. El tercer dipòsit, RACO (www.raco.cat), s'ha posat en marxa a març de 2006, fent possible la consulta, en accés obert, dels articles a text complet de revistes científiques, culturals i erudites catalanes. Per al desenvolupament de tots tres dipòsits s'ha usat programari lliure. Per al TDX es va adaptar l'Electronic Theses and Dissertations (ETD) de la Universitat de Virgina Tech. Per a RECERCAT, el DSpace, fet pel Massachusetts Institute of Technology (MIT) i Hewlett-Packard (HP). I per a RACO s'ha fet servir el Open Journal Systems (OJS) del Public Knowledge Project (PKP). La comunicació pretén explicar breument què són aquests tres dipòsits, els beneficis obtinguts pel fet que hagin estat desenvolupats sota programari lliure i que les tesis, els documents de recerca i les revistes que contenen siguin en accés obert. Programari lliure i accés obert, un binomi guanyador.

The Catalan countries project (1931-1939)

In the evolution of Catalan nationalism, as much politician as cultural, the period of II Spanish Republic (1931-1939) was essential. The obtaining of the Statute of Autonomy (1931-1932) supposed the beginning of a stage of expansion in multiple aspects. One of them were the contacts with the Catalanists nuclei of the rest of the cultural space of Catalan language in which, at that time, it would begin to call Catalan Countries (Balearic Islands, Valencian Country, Andorra, Rosselló, to l'Alguer). On Those Collaborations between cultural organizations, political and particular parties Catalonia always will be the model to follow. The Increasing connections will be visualized on press, as well as on cultural celebrations, policy of parties and Constituent Courts. This evolution will be cut by the Franco victory in the Civil War in 1939.

Transferring QTL technology to the pig breeding industry (PigQTech) - a demonstration project

The aim of the project has been to demonstrate how the farm animal breeding industry can utilise gene mapping technology to accelerate genetic improvement. Previous theoretical studies had suggested that the use of marker assisted selection could potentially increase the annual improvement for quantitative traits like backfat with about 10% and for more difficult traits such as meat quality and reproduction by as much as 40-60% compared with existing technology. The work has comprised two major tasks: 1. Commercially relevant populations have been screened for segregation at QTLs identified in experimental populations. The aim has been to establish optimal strategies for QTL detection in commercial pig populations and the extent to which QTLs explaining major phenotypic differences between divergent lines used in experimental studies also explain quantitative variation within commercial lines. The results are important for specifying future strategies for finding economically valuable QTLs. 2. Marker assisted backcrossing has been used to demonstrate how a QTL allele can be introgressed from one breed to another. The work has focused on the major fatness QTL on pig chromosome 4 previously identified in a wild pig/Large White intercross. The end result was not designed to be a commercially viable product in its own right, but the process has validated a number of points of major importance for the exploitation of QTLs in livestock.

Percepción del riesgo de los agroquímicos en la localidad de Basavilbaso, Entre Ríos

El modelo agrario argentino actual se basa en el monocultivo de la soja para la exportación. Este cultivo aumentó de forma masiva a partir de la entrada de la soja transgénica resistente al herbicida glifosato, en los 90. Los plaguicidas han representado el gran sostén del crecimiento de la producción agropecuaria argentina. Debido al uso creciente que están teniendo y a la proximidad de los cultivos a los pueblos, los habitantes empiezan a percibir las prácticas de manejo y aplicación de plaguicidas como un riesgo para su salud y el medio ambiente de la zona. El clima de incertidumbre acerca de los impactos de los agroquímicos se percibe en las áreas productoras de soja, convirtiéndose en un conflicto entre expertos y población local. Con el estudio de este riesgo, del modo en que es percibido por la población y de los factores que causan dicha percepción, se ha observado que los problemas que generan la elevada percepción son principalmente las malas prácticas en la aplicación de los agroquímicos, la ausencia de regulación del organismo de control y la incertidumbre sobre los efectos que dichos productos pueden causar.

Inequality and a repeated joint project

Agents voluntarily contribute to an infinitely repeated joint project. We investigate the conditions for cooperation to be a renegotiation-proof and coalition-proof equilibrium before examining the influence of output share inequality on the sustainability of cooperation. When shares are not equally distributed, cooperation requires agents to be more patient than under perfect equality. Beyond a certain degree of share inequality, full efficiency cannot be reached without redistribution. This model also explains the coexistence of one cooperating and one free-riding coalition. In this case, increasing inequality can have a positive or negative impact on the aggregate level of effort.

Behind the Scenes of an Ant Genome Project

Dramatic improvements in DNA sequencing technologies have led to amore than 1,000-fold reduction in sequencing costs over the past five years.Genome-wide research approaches can thus now be applied beyond medicallyrelevant questions to examine the molecular-genetic basis of behavior,development and unique life histories in almost any organism. A first step foran emerging model organism is usually establishing a reference genomesequence. I offer insight gained from the fire ant genome project. First, I detailhow the project came to be and how sequencing, assembly and annotationstrategies were chosen. Subsequently, I describe some of the issues linked toworking with data from recently sequenced genomes. Finally, I discuss anapproach undertaken in a follow-up project based on the fire ant genomesequence.

The Importance of Revenue Sharing for the Local Economic Impacts of a Renewable Energy Project: A Social Accounting Matrix Approach

As demand for electricity from renewable energy sources grows, there is increasing interest, and public and financial support, for local communities to become involved in the development of renewable energy projects. In the UK, “Community Benefit” payments are the most common financial link between renewable energy projects and local communities. These are “goodwill” payments from the project developer for the community to spend as it wishes. However, if an ownership stake in the renewable energy project were possible, receipts to the local community would potentially be considerably higher. The local economic impacts of these receipts are difficult to quantify using traditional Input-Output techniques, but can be more appropriately handled within a Social Accounting Matrix (SAM) framework where income flows between agents can be traced in detail. We use a SAM for the Shetland Islands to evaluate the potential local economic and employment impact of a large onshore wind energy project proposed for the Islands. Sensitivity analysis is used to show how the local impact varies with: the level of Community Benefit payments; the portion of intermediate inputs being sourced from within the local economy; and the level of any local community ownership of the project. By a substantial margin, local ownership confers the greatest economic impacts for the local community.
