Computational aspects in checking of coherence and propagation of conditional probability bounds
2000
In this paper we consider the problem of reducing the computational difficulties in g-coherence checking and propagation of imprecise conditional probability assessments. We review some theoretical results related with the linear structure of the random gain in the betting criterion. Then, we propose a modi ed version of two existing algorithms, used for g-coherence checking and propagation, which are based on linear systems with a reduced number of unknowns. The reduction in the number of unknowns is obtained by an iterative algorithm. Finally, to illustrate our procedure we give some applications.
Algorithms for coherence checking and propagation of conditional probability bounds
2001
In this paper, we propose some algorithms for the checking of generalized coherence (g-coherence) and for the extension of imprecise conditional probability assessments. Our concept of g-coherence is a generalization of de Finetti’s coherence principle and is equivalent to the ”avoiding uniform loss” property for lower and upper probabilities (a la Walley). By our algorithms we can check the g-coherence of a given imprecise assessment and we can correct it in order to obtain the associated coherent assessment (in the sense of Walley and Williams). Exploiting some properties of the random gain we show how, in the linear systems involved in our algorithms, we can work with a reduced set of va…
Colonoscopic screening of first-degree relatives of patients with large adenomas: increased risk of colorectal tumors.
2007
International audience; Background & Aims: The risk of developing colorectal neoplasia is not well established among family members of individuals with large adenomas and screening strategies remain under debate in this population. This study aimed at quantifying the risk of colorectal adenomas and cancers using colonoscopic screening in first-degree relatives of patients with large adenomas. Methods: This case-control study was performed in 18 endoscopic units of French non-University Hospitals. A colonoscopy was offered to first-degree relatives of 306 index cases with adenomas ≥ 10 mm, if they were alive, aged 40-75 and could be contacted by the index case. Among 674 relatives meeting th…
Catholic Religious Practices Questionnaire (CRPQ): Construction and Analysis of Psychometric Properties
2022
Members of the Catholic Church express their faith in a variety of manners, in general with a focus on liturgical and popular forms of piety. This article provided construction and initial validation for a brief questionnaire to measure Catholic religious practices. The authors used Sample 1 (n = 219) for exploratory factor analysis and Sample 2 (n = 181) for confirmatory factor analysis and to test the validity of a new scale. A model with two factors with five items each provided a good fit. The Catholic Religious Practices Questionnaire (CRPQ) consists of two subscales: official religiosity and folk practices. Both exhibit positive though varying correlations with the Centrality of Relig…
Assessment itineraries and its relation with academic achievement
2017
[EN] In recent years the university educational reality shows signs of change. Among other innovations, it has meant the introduction of new ways of assessment, arousing the scientific interest it deserves. Concretely, the formative and shared assessment is developed in assessment routes that try to adapt to the needs of the students. However, the continuous, mixed and final assessment methods are related to different academic performance, which is worth considering. This article tries to deepen in the relation that these itineraries have with the obtained marks and analyses descriptively teacher assessment trends and students’ system assessment preferences of choice. The results show, on t…
Problemi attuali della valutazione della ricerca giuridica
2016
The present contribution aims at underlying that the research quality assessment, beyond the debate on the functions of its system, is nowadays - even in the field of legal research - a fundamental tool for related public policies. At the same time, the increasing complexity of the evaluation's systems and methods is taken into account, especially with regard to the peculiarities of research in the legal field. Examples thereof may be found in the relationship between theory and praxis, in the importance of vocational training and, more generally, of didactics, as well as in the international dimension of the legal problems and in the growing tendency to provide researches, including the le…
Nitrate and nitrite in the diet: How to assess their benefit and risk for human health
2015
Nitrate is a natural constituent of the human diet and an approved food additive. It can be partially converted to nitrogen monoxide, which induces vasodilation and thereby decreases blood pressure. This effect is associated with a reduced risk regarding cardiovascular disease, myocardial infarction, and stroke. Moreover, dietary nitrate has been associated with beneficial effects in patients with gastric ulcer, renal failure, or metabolic syndrome. Recent studies indicate that such beneficial health effects due to dietary nitrate may be achievable at intake levels resulting from the daily consumption of nitrate-rich vegetables. N-nitroso compounds are endogenously formed in humans. However…
FMECA Application in Tomotherapy: Comparison between Classic and Fuzzy Methodologies
2022
Accident analysis in radiotherapy highlighted the need to increase quality assurance (QA) programs by the identification of failures/errors with very low probability (rare event) but very severe consequences. In this field, a Failure Mode, Effects and Criticality Analysis (FMECA) technique, used in various industrial processes to rank critical events, has been met with much interest. The literature describes different FMECA methods; however, it is necessary to understand if these tools are incisive and effective in the healthcare sector. In this work, comparisons of FMECA methodologies in the risk assessment of patients undergoing treatments performed with helical tomotherapy are reported. …
Sull’inquadramento sistematico e sulla natura giuridica degli accordi preventivi per le imprese con attività internazionale e sulla loro estensibilit…
2019
L’articolo intende affrontare tre questioni specifiche che sorgono con riguardo all’istituto degli accordi preventivi per le imprese con attività internazionale. La prima è quella concernente la natura giuridica di tali accordi, che, secondo la dottrina maggioritaria, sarebbe dichiarativa e non negoziale. La seconda riguarda il rapporto esistente fra il nuovo istituto e gli interpelli. Analisi che viene effettuata anche mettendo in risalto i profili di innovazione che gli «accordi preventivi» presentano rispetto al previgente ruling internazionale. La terza concerne la possibilità di estendere gli effetti degli accordi anche all’IVA, con particolare riferimento al problema della stabile org…
Cardiorespiratory Fitness and the Risk of Serious Ventricular Arrhythmias: A Prospective Cohort Study.
2019
Cardiorespiratory fitness (CRF) is an established risk factor for cardiovascular disease outcomes. However, the relationship of CRF with risk of ventricular arrhythmias (VAs) is unknown. We aimed to assess the prospective association of CRF with the risk of serious VAs. Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed using a respiratory gas exchange analyzer in 2299 middle-aged men in the Kuopio Ischemic Heart Disease prospective cohort. We corrected for within-person variability in CRF levels using data from repeated measurements 11 years apart. During median follow-up of 25.3 years (interquartile range, 18.7-27.2 years), 73 serious VAs were recorded. The age-…
