Elements of Resource Representation in Institutional Repositories: a Bibliographic Review

This review focuses on identifying how the literature studies the existing problems in the Resource Representation (RR) of Institutional Repositories (IR). RR is a process of recording in a persistent manner a set of data (metadata) as a synthesis and replacement of the "real" object, to allow its identification, retrieval and dissemination. RR is defined by certain elements: resources, metadata schema, storage and cataloging. On the other hand, IRs are based on functional processes according to the material that is deposited and the ISO 14.721 standard: ingest, storage, cataloging, indexing, search engine and browsing. The results of this review show that identifying the problems found in these elements and functional processes is not a subject of study for the researchers, which leads to a vacant area in this field, and in this way to solve some of the problems present in the RI, from the point of view of functional elements and processes

Recepción de estructuras de hormigón: comparación de los criterios adoptados por los distintos códigos y reglamentos

Se hace un análisis comparativo de los criterios de evaluación que distintos reglamentos de seguridad estructural aplican para la recepción del hormigón. Dichos criterios fueron aplicados a ensayos de control de calidad disponibles de diversas obras en las cuales participaron los autores. Comprende hormigones de Clase H-170 a H-500 con desviaciones normales variables entre 25 kgf/cm2 y 40 kgf/cm2 Se informan los resultados obtenidos, incluyendo los volúmenes de hormigón rechazados según los diferentes criterios reglamentarios

The TRUST Principles for digital repositories.

As information and communication technology has become pervasive in our society, we are increasingly dependent on both digital data and repositories that provide access to and enable the use of such resources. Repositories must earn the trust of the communities they intend to serve and demonstrate that they are reliable and capable of appropriately managing the data they hold. Following a year-long public discussion and building on existing community consensus1, several stakeholders, representing various segments of the digital repository community, have collaboratively developed and endorsed a set of guiding principles to demonstrate digital repository trustworthiness. Transparency, Responsibility, User focus, Sustainability and Technology: the TRUST Principles provide a common framework to facilitate discussion and implementation of best practice in digital preservation by all stakeholders.Proyecto de Enlace de Biblioteca

Simulation framework for teaching in modeling and simulation areas

Simulation is the process of executing a model that describes a system with enough detail; this model has its entities, an internal state, some input and output variables and a list of processes bound to these variables. Teaching a simulation language such as general purpose simulation system (GPSS) is always a challenge, because of the way it executes the models and the abstraction level it can achieve, very different compared with most well-known programming languages. This article presents an open source simulation framework that implements a subset of entities of GPSS, which could help students to improve the understanding of this language. This tool also stores all entities of simulations in every single simulation time, which is very useful for debugging simulations, but also for getting a detailed history of all entities in the simulations, knowing exactly how they have behaved in every simulation time.Proyecto de Enlace de Bibliotecas (PrEBi

Los principios TRUST en los repositorios digitales

Con la adopción cada vez más generalizada de las TICs en nuestra sociedad, dependemos cada vez más de los datos digitales y de los repositorios que brindan acceso a ese tipo de recursos y nos permiten utilizarlos. Los repositorios deben ganarse la confianza de las comunidades a las que pretenden brindar servicios y demostrar que son confiables y capaces de administrar adecuadamente los datos que contienen. Tras un debate público que se prolongó durante un año y en función del consenso actual de la comunidad, varias partes interesadas, que representan diversos segmentos de la comunidad de los repositorios digitales, han colaborado para desarrollar y avalar un conjunto de principios rectores, para demostrar que el repositorio digital es confiable. Estos principios abarcan la Transparencia, la Responsabilidad, el Foco en el Usuario, la Sostenibilidad y la Tecnología, y presentan un marco común para facilitar el debate y la implementación de las mejores prácticas en cuanto a preservación digital en beneficio de todas las partes interesadas.Este artículo es una traducción de: Lin, D., Crabtree, J., Dillo, I., Downs, R.

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
