Scientific Production on Open Access : A Worldwide Bibliometric Analysis in the Academic and Scientific Context

This research aims to diachronically analyze the worldwide scientific production on open access, in the academic and scientific context, in order to contribute to knowledge and visualization of its main actors. As a method, bibliographical, descriptive and analytical research was used, with the contribution of bibliometric studies, especially the production indicators, scientific collaboration and indicators of thematic co-occurrence. The Scopus database was used as a source to retrieve the articles on the subject, with a resulting corpus of 1179 articles. Using Bibexcel software, frequency tables were constructed for the variables, and Pajek software was used to visualize the collaboration network and VoSViewer for the construction of the keywords' network. As for the results, the most productive researchers come from countries such as the United States, Canada, France and Spain. Journals with higher impact in the academic community have disseminated the new constructed knowledge. A collaborative network with a few subnets where co-authors are from different countries has been observed. As conclusions, this study allows identifying the themes of debates that mark the development of open access at the international level, and it is possible to state that open access is one of the new emerging and frontier fields of library and information science

La política demográfica del tercer gobierno peronista: justificaciones, repercusiones y resistencias a las restricciones al control de la natalidad (1973-1976)

Desde mediados de la década del '50, el tamaño de la población comenzó a ser considerado en relación a necesidades geopolíticas y proyectos de desarrollo, mientras proliferaban organismos internacionales decididos a influir sobre las conductas reproductivas de los países del Tercer Mundo. En este contexto, Argentina defendió su autonomía e intentó diseñar una política de población que atendiera a su particular situación de caída demográfica. El tercer gobierno peronista incluyó esta problemática en su plan de gobierno y fue más allá de lo discursivo al implementar, por primera vez en el país, medidas coercitivas sobre el libre acceso a la anticoncepción. Estas disposiciones generaron importantes debates sociales que se expresaron en los medios de prensa escrita, al interior de la corporación médica y en las calles, a través del accionar del movimiento feminista y el Frente de Liberación Homosexual. En este artículo nos proponemos iluminar este aspecto poco estudiado por la historiografía, reconstruyendo la cosmovisión de la época sobre el problema demográfico, las contradicciones al interior del gobierno respecto a las medidas a seguir, sus repercusiones y las resistencias que generaron. Consideramos necesario conocer con mayor profundidad este tema y sus perdurables consecuencias negativas en la 'cultura anticonceptiva' del país.

Solución de gestión y control de la integridad de pozos

El objetivo de este proyecto es la creación de un modelo de gestión y control de la integridad de pozo, basado en el seguimiento de la operación y el análisis de su diseño y construcción. Para ello se diseña una herramienta tecnológica que permita disponer de la información necesaria y gestionarla según estándares internacionales. En la fase inicial del proyecto se realizó una revisión bibliográfica de los estudios más relevantes sobre integridad de pozos, tanto de la asociación SPE (Society of Petroleum Engineers), de Universidades de Noruega y México, o de empresas como ECOPETROL, con el fin entrar en el contexto y analizar antecedentes de modelos y herramientas similares. En segundo lugar se ha realizado un estudio de las bases de datos, comenzando por un análisis de los estándares de PPDM (The Professional Petroleum Data Management Association) sobre los que se realiza la herramienta y se ha seleccionado la base de datos que más se adecua a la herramienta, considerando Access como la mejor opción por ser de fácil acceso e incorporar el módulo de informes. Para la creación de la solución se diseñó un modelo de datos, condicionado por los requisitos de integridad de pozos de la normativa noruega NORSOK D-010 y de la guía de recomendaciones para la integridad de pozos de la asociación de petróleo y gas de Noruega. La materialización de este modelo se realizó mediante la creación de una base de datos en la plataforma Access, y empleando lenguaje propio de Access combinado con programación SQL. Una vez definido y construido el modelo de datos, es posible crear una capa de visualización de la información. Para ello se define un informe de estado de pozo. Este informe será visible por el usuario según sus roles y responsabilidades. ABSTRACT The objective of this project is to create a model for managing and controlling the well integrity. It is based on the monitoring of the operation and the analysis of its design and construction. Therefore a technological tool is designed; to allow having the necessary information and to manage it according to international standards. At the beginning of the project, a literature review of the most relevant studies on well integrity was performed. It was made to enter into context and to analyze the history of the models and available similar tools. It included texts from the association SPE (Society of Petroleum Engineers), universities from Norway and Mexico, and companies like ECOPETROL. Secondly there has been a study of the databases. It began with an analysis of PPDM (The Professional Petroleum Data Management Association) standards; about which, the tool is made. After the analysis, Access was considered the best option because it is easily accessible and incorporates the reporting module. In order to create the solution a data model was designed. It was conditioned by the requirements of integrity of wells, in the Norwegian standards and in the NORSOK D010 recommendations guide for well integrity of the Norwegian oil and gas Association. This model was performed by a database in the Access platform, and using Access language, combined with SQL programming. Once the data model is defined and built, it is possible to create a layer of data visualization. A report of this well is defined to create it. This report will be visible for the user according to their roles and responsibilities.

Changes in Access to Health Services of the Immigrant and Native-Born Population in Spain in the Context of Economic Crisis

Aim: To analyze changes in access to health care and its determinants in the immigrant and native-born populations in Spain, before and during the economic crisis. Methods: Comparative analysis of two iterations of the Spanish National Health Survey (2006 and 2012). Outcome variables were: unmet need and use of different healthcare levels; explanatory variables: need, predisposing and enabling factors. Multivariate models were performed (1) to compare outcome variables in each group between years, (2) to compare outcome variables between both groups within each year, and (3) to determine the factors associated with health service use for each group and year. Results: unmet healthcare needs decreased in 2012 compared to 2006; the use of health services remained constant, with some changes worth highlighting, such as the decline in general practitioner visits among autochthons and a narrowed gap in specialist visits between the two populations. The factors associated with health service use in 2006 remained constant in 2012. Conclusion: Access to healthcare did not worsen, possibly due to the fact that, until 2012, the national health system may have cushioned the deterioration of social determinants as a consequence of the financial crisis. Further studies are necessary to evaluate the effects of health policy responses to the crisis after 2012.

European antitrust control and standard setting. Bruegel Working Paper 2013/01, February 2012

Standards reduce production costs and increase products’ value to consumers. Standards however entail risks of anti-competitive abuse. After the adoption of a standard, the chosen technology normally lacks credible substitutes. The owner of the patented technology might thus have additional market power relative to locked-in licensees, and might exploit this power to charge higher access rates. In the economic literature this phenomenon is referred to as ‘hold-up’. To reduce the risk of hold-up, standard-setting organisations often require patent holders to disclose their standard-essential patents before the adoption of the standard and to commit to license on fair, reasonable and non-discriminatory (FRAND) terms. The European Commission normally investigates unfair pricing abuse in a standard-setting context if a patent holder who committed to FRAND ex-ante is suspected not to abide to it ex-post. However, this approach risks ignoring a number of potential abuses which are likely harmful for welfare. That can happen if, for example, ex-post a licensee is able to impose excessively low access rates (‘reverse hold-up’) or if a patent holder acquires additional market power thanks to the standard but its essential patents are not encumbered by FRAND commitments, for instance because the patent holder did not directly participate to the standard setting process and was therefore not required by the standard-setting organisations to commit to FRAND ex-ante. A consistent policy by the Commission capable of tackling all sources of harm should be enforced regardless of whether FRAND commitments are given. Antitrust enforcement should hinge on the identification of a distortion in the bargaining process around technology access prices, which is determined by the adoption of the standard and is not attributable to pro-competitive merits of any of the involved players.

(Table1) Sedimentation rates and age-control points form ODP Hole 152-919A

Planktic d18O and d13C records and point count records of biogenic, volcanic, and nonvolcanic terrigenous [ice-rafted debris (IRD)] sediment components from Hole 919A in the Irminger basin, northern North Atlantic provide a comprehensive dataset from which a paleoceanographic reconstruction for the last 630 kyr has been developed. The paleoceanographic evolution of the Irminger basin during this time contains both long-term patterns and significant developmental steps. One long-term pattern observed is the persistent deposition of hematite-stained ice-rafted debris. This record suggests that the modern and late Pleistocene discharges of icebergs from northern redbed regions to the Irminger Sea lie in the low end of the range observed over the last 630 kyr. In addition, Arctic front fluctuations appear to have been the main controlling factor on the long-term accumulation patterns of IRD and planktic biogenic groups. The Hole 919A sediment record also contains a long-term association between felsic volcanic ash abundances and light d18O excursions in both interglacial and glacial stages, which suggests a causal link between deglaciations and explosive Icelandic eruptions. A significant developmental step in the paleoceanographic reconstruction based on benthic evidence was for diminished supply of Denmark Strait Overflow Water (DSOW) beginning at ~380 ka, possibly initiated by the influx of meltwater from broad-scale iceberg discharges along the east Greenland coast. There is also planktic evidence of a two-step cooling of sea surface conditions in the Irminger basin, first at ~338-309 ka and later at ~211-190 ka, after which both glacials and interglacials were colder as the Arctic front migrated southeast of Site 919. In addition to offering these findings, this reconstruction provides a longer-term geologic context for the interpretation of more recent paleoceanographic events and patterns of deposition from this region.

Improving learning in undergraduate control engineering courses using context-based learning models

Control Engineering is an essential part of university electrical engineering education. Normally, a control course requires considerable mathematical as well as engineering knowledge and is consequently regarded as a difficult course by many undergraduate students. From the academic point of view, how to help the students to improve their learning of the control engineering knowledge is therefore an important task which requires careful planning and innovative teaching methods. Traditionally, the didactic teaching approach has been used to teach the students the concepts needed to solve control problems. This approach is commonly adopted in many mathematics intensive courses; however it generally lacks reflection from the students to improve their learning. This paper addresses the practice of action learning and context-based learning models in teaching university control courses. This context-based approach has been practised in teaching several control engineering courses in a university with promising results, particularly in view of student learning performances.

Co-opting conservation: Migrant resource control and access to national park management in the Philippine uplands

The history of political and economic inequality in forest villages can shape how and why resource use conflicts arise during the evolution of national parks management. In the Philippine uplands, indigenous peoples and migrant settlers co-exist, compete over land and forest resources, and shape how managers preserve forests through national parks. This article examines how migrants have claimed lands and changed production and exchange relations among the indigenous Tagbanua to build on and benefit from otherwise coercive park management on Palawan Island, the Philippines. Migrant control over productive resources has influenced who, within each group, could sustain agriculture in the face of the state's dominant conservation narrative - valorizing migrant paddy rice and criminalizing Tagbanua swiddens. Upon settling, migrant farmers used new political and economic strengths to tap into provincial political networks in order to be hired at a national park. As a result, they were able to steer management to support paddy rice at the expense of swidden cultivation. While state conservation policy shapes how national parks impact upon local resource access and use, older political economic inequalities in forest villages build on such policies to influence how management affects the livelihoods of poor households.

Using machine vision classification to control access of animals to water

Invasive vertebrate pests together with overabundant native species cause significant economic and environmental damage in the Australian rangelands. Access to artificial watering points, created for the pastoral industry, has been a major factor in the spread and survival of these pests. Existing methods of controlling watering points are mechanical and cannot discriminate between target species. This paper describes an intelligent system of controlling watering points based on machine vision technology. Initial test results clearly demonstrate proof of concept for machine vision in this application. These initial experiments were carried out as part of a 3-year project using machine vision software to manage all large vertebrates in the Australian rangelands. Concurrent work is testing the use of automated gates and innovative laneway and enclosure design. The system will have application in any habitat throughout the world where a resource is limited and can be enclosed for the management of livestock or wildlife.
