Contenido factorial y comercio España-Mercosur
1999
El presente artículo analiza las características asociadas al comercio España-Mercosur a través de la estimación de sus factores determinantes. Este ejercicio supone la aplicación de diversas técnicas de análisis económico, las cuales se basan en el Teorema de Heckscher y Ohlin. El resultado de la estimación permite evidenciar que la economía española se revela como relativamente abundante en capital humano frente al Mercosur, mientras que el Mercosur se revela como relativamente abundante en capital físico respecto de la economía española lo que supone un resultado del tipo «paradoja de Leontieff». Los resultados obtenidos permiten recomendar la intensificación de las relaciones comerciale…
Modular Strategies for Recursive Game Graphs
2006
AbstractMany problems in formal verification and program analysis can be formalized as computing winning strategies for two-player games on graphs. In this paper, we focus on solving games in recursive game graphs which can model the control flow in sequential programs with recursive procedure calls. While such games can be viewed as the pushdown games studied in the literature, the natural notion of winning in our framework requires the strategies to be modular with only local memory; that is, resolution of choices within a module does not depend on the context in which the module is invoked, but only on the history within the current invocation of the module. While reachability in (global…
A Generic Approach to Scheduling and Checkpointing Workflows
2018
This work deals with scheduling and checkpointing strategies to execute scientific workflows on failure-prone large-scale platforms. To the best of our knowledge, this work is the first to target fail-stop errors for arbitrary workflows. Most previous work addresses soft errors, which corrupt the task being executed by a processor but do not cause the entire memory of that processor to be lost, contrarily to fail-stop errors. We revisit classical mapping heuristics such as HEFT and MinMin and complement them with several checkpointing strategies. The objective is to derive an efficient trade-off between checkpointing every task (CkptAll), which is an overkill when failures are rare events, …
Empirically Determined, Psychopathological Subtypes in Children With ADHD
2013
OBJECTIVE: The aim of this study was to empirically determine subgroups of ADHD defined by specific patterns of psychopathology. METHOD: A clinical sample of 223 children with ADHD, aged 5 to 14 years, was examined with the Child Behavior Checklist (CBCL). In addition, comorbid psychiatric disorders, psychosocial risk factors, and socioeconomic status were assessed. RESULTS: Cluster analysis of CBCL subscales yielded a solution with four distinct subgroups. While "externalizers" showed a high rate of comorbid oppositional defiant disorder (ODD) and conduct disorder (CD), "obsessive-compulsives" exhibited thought problems, low rates of comorbid CD, and high symptoms of inattention. "High psy…
Is participation in the tourism market an opportunity for everyone? Some evidence from Italy
2016
This paper investigates whether there are differences in tourism consumption behaviour among families by analysing the main determinants of tourism participation at national and international levels. In particular, it explores whether tourism is becoming part of the lifestyle of Italians or whether it is still a luxury good only for the privileged. A Heckman model was used on micro-data on Italian family expenditure over the period 1997–2007, and an income elasticity analysis for different personal and household characteristics was carried out. The results show that participation in the tourism market is strongly affected by the personal characteristics of individuals and that tourism cons…
Control Flow Error Checking with ISIS
2005
The Interleaved Signature Instruction Stream (ISIS) is a signature embedding technique that allows signatures to co-exist with the main processor instruction stream with a minimal impact on processor performance, without sacrificing error detection coverage or latency. While ISIS incorporate some novel error detection mechanisms to assess the integrity of the program executed by the main processor, the limited number of bits available in the signature control word question if the detection mechanisms are effective detecting errors in the program execution flow. Increasing the signature size would negatively impact the memory requirements, so this option has been rejected. The effectiveness …
Problemas adolescentes en Iberoamérica
2002
Data gathered in an Iberoamerican descriptive-comparative study on adolescent students are reported. Samples include subjects living in three different Argentine urban regions (Buenos Aires, Tucuman and Patagonia) and in the city of Valencia (Spain). For psychological assessment the Symptom Checklist (SCL – 90 – R), a sociodemographic survey including an open question on the most important emotional problem experienced during last year and a coping scale, in their Spanish versions, were used. We present data on reported problems, analyzed by sex, age and region, pointing out main differences found.
Meeting Report from the Second “Minimum Information for Biological and Biomedical Investigations” (MIBBI) workshop
2011
This report summarizes the proceedings of the second workshop of the ‘Minimum Information for Biological and Biomedical Investigations’ (MIBBI) consortium held on Dec 1–2, 2010 in Rudesheim, Germany through the sponsorship of the Beilstein-Institute. MIBBI is an umbrella organization uniting communities developing Minimum Information (MI) checklists to standardize the description of data sets, the workflows by which they were generated and the scientific context for the work. This workshop brought together representatives of more than twenty communities to present the status of their MI checklists and plans for future development. Shared challenges and solutions were identified and the role…

Association of Nursing Practice Environment on reported adverse events in private management hospitals: A cross‐sectional study
2021
Aims and objectives To examine the relationships between nurses' perceptions of their practice environment, other working conditions and reported adverse events in two private management hospitals. Background Patient safety is influenced by knowledge, available resources and the context in which nursing care is provided. In this sense, it has been found that certain work environments (e.g., workload, nurse turnover level, patient-to-nurse ratio, nurse staffing, nurse manager ability) influence patient outcomes. The association between nursing practice environment and reported adverse events has not been explored in private management hospitals. Design A cross-sectional study. The STROBE was…
