On general conditional prevision assessments
2009
In this paper we consider general conditional random quantities of the kind $X|Y$, where $X$ and $Y$ are finite discrete random quantities. Then, we introduce the notion of coherence for conditional prevision assessments on finite families of general conditional random quantities. Moreover, we give a compound prevision theorem and we examine the relation between the previsions of $X|Y$ and $Y|X$. Then, we give some results on random gains and, by a suitable alternative theorem, we obtain a characterization of coherence. We also propose an algorithm for the checking of coherence. Finally, we briefly examine the case of imprecise conditional prevision assessments by introducing the notions of…
Chernobyl exposure as stressor during pregnancy and behaviour in adolescent offspring.
2007
Objective: Research in animals has shown that exposure to stressors during pregnancy is associated with offspring behavioural disorders. We aimed to study the effect of in utero exposure to the Chernobyl disaster in 1986, and maternal anxiety presumably associated with that exposure, on behaviour disorder observed at age 14. Method: Exposed (n = 232) and non-exposed Finnish twins (n = 572) were compared. A semi-structured interview was used to assess lifetime symptoms of depression, generalized anxiety disorder, attention deficit hyperactivity disorder, conduct disorder and oppositional defiant disorder symptoms. Results: Adolescents who were exposed from the second trimester in pregnancy o…
On utilizing dependence-based information to enhance micro-aggregation for secure statistical databases
2011
Published version of an article in the journal: Pattern Analysis and Applications. Also available from the publisher at: http://dx.doi.org/10.1007/s10044-011-0199-9 We consider the micro-aggregation problem which involves partitioning a set of individual records in a micro-data file into a number of mutually exclusive and exhaustive groups. This problem, which seeks for the best partition of the micro-data file, is known to be NP-hard, and has been tackled using many heuristic solutions. In this paper, we would like to demonstrate that in the process of developing micro-aggregation techniques (MATs), it is expedient to incorporate information about the dependence between the random variable…
A questionnaire to collect unintended effects of transcranial magnetic stimulation: A consensus based approach
2022
Transcranial magnetic stimulation (TMS) has been widely used in both clinical and research practice. However, TMS might induce unintended sensations and undesired effects as well as serious adverse effects. To date, no shared forms are available to report such unintended effects. This study aimed at developing a questionnaire enabling reporting of TMS unintended effects. A Delphi procedure was applied which allowed consensus among TMS experts. A steering committee nominated a number of experts to be involved in the Delphi procedure. Three rounds were conducted before reaching a consen-sus. Afterwards, the questionnaire was publicized on the International Federation of Clinical Neurophysiolo…
Corticosteroids in oncology: Use, overuse, indications, contraindications. An Italian Association of Medical Oncology (AIOM)/ Italian Association of …
2022
Corticosteroids (CSs) are widely used in oncology, presenting several different indications. They are useful for induction of apoptosis in hematological neoplasms, for management of anaphylaxis and cytokine release/hypersensitivity reaction and for the symptomatic treatment of many tumour- and treatment-related complications. If the employment of CSs in the oncological setting results in several benefits for patients and satisfaction for clinicians, on the other hand, many potential adverse events (AEs), both during treatment and after withdrawal of CSs, as well as the duality of the effects of these compounds in oncology, recommend being cautious in clinical practice. To date, several gray…
Random Variables Recorded Under Mutually Exclusive Conditions: Contextuality-by-Default
2014
We present general principles underlying analysis of the dependence of random variables (outputs) on deterministic conditions (inputs). Random outputs recorded under mutually exclusive input values are labeled by these values and considered stochastically unrelated, possessing no joint distribution. An input that does not directly influence an output creates a context for the latter. Any constraint imposed on the dependence of random outputs on inputs can be characterized by considering all possible couplings (joint distributions) imposed on stochastically unrelated outputs. The target application of these principles is a quantum mechanical system of entangled particles, with directions of …
Cambios de Identidad asociados a la vivencia de una transición ritualizada: aprobar una oposición
2008
This qualitative research study depicts the main categories obtained by means of an inductive methodology based on the content analysis of 8 interviews using the N’Vivo program. The sample consisted of 8 men (between 26 and 45 years) who had passed a competitive examination. We take into consideration whether this life event and its related transition is an example of a contemporary rite of passage. We focus on changes reported by the subjects once the developmental transition was over. These changes are related to new social identities. The most relevant psychological and structural processes in order to get this kind of optimal changes are also discussed.
Organizational Learning Capability and Job Satisfaction: an Empirical Assessment in the Ceramic Tile Industry
2009
Organizational learning capability has been considered an essential issue of an organization's effectiveness and potential to innovate and grow. Although its positive effects on organizations and employees are generally assumed, there is no empirical evidence of its positive association with employee attitudes such as job satisfaction. This paper aims to investigate the relationship between organizational learning capability and job satisfaction through the questionnaire responses of 157 employees from eight companies in the Spanish ceramic tile industry. Results suggest that organizational learning capability and job satisfaction are strongly linked.
Moderating influence of organizational justice on the relationship between job insecurity and its outcomes: A multilevel analysis
2010
A great amount of research has illustrated the evident prevalence of job insecurity in working life and its harmful outcomes for employees and organizations. Some authors have identified factors that can reduce this negative influence. However, up until now, most of these factors have only been studied at an individual level, without taking into account the fact that contextual conditions can play a moderating role in organizations. Following this perspective, this article analyses the moderator role of organizational justice and organizational justice climate in the relationship between job insecurity and its outcomes. The study was carried out with a sample of 942 employees from 47 Spanis…
Cognitive emotion regulation and psychopathology across cultures: A comparison between six European countries
2016
Abstract Use of cognitive emotion regulation strategies in response to stressful life events varies by country, though research has been limited to comparisons between American and Asian cultures. This study aimed to compare six European countries to investigate cross-cultural differences in the use of cognitive strategies and test if the relationship between specific strategies and psychopathology varies across countries. Data arrays were collected from the Netherlands, Hungary, Spain, Italy, Portugal and Germany (N = 1553) and cross-cultural measures of cognitive emotion regulation using the Cognitive Emotion Regulation Questionnaire (CERQ) were included. Measures of depression and anxiet…
