The role of different game-genres in predicting internet gaming disorder (IGD)
2020
Introduction: Internet gaming disorder (IGD) is a new diagnosis in DSM 5 worth of research. New potentially addictive features are emerging in pay- and free-to-play videogames, involving different at-risk populations of gamers. However, few studies have examined whether and how different game-genres can contribute to the risk of IGD. Objectives: This study aimed to investigate how game-genres can predict IGD, accounting for alexithymia scores, time-related play- ing habits, and other predictors. Methods: Participants were gamers joining online communities, surveyed about which games they played more than 20 hours in their lifetime, time-variables, other stressors and alexithymia scores. A s…
Interoceptive Abilities in Inflammatory Bowel Diseases and Irritable Bowel Syndrome
2020
International audience; Alexithymia is usually described by three main dimensions difficulty identifying feelings (DIF), difficulty describing feelings (DDF), and externally oriented thinking (EOT). The most commonly used questionnaire investigating alexithymia, the Toronto Alexithymia Scale (TAS-20), supports this three-factor structure. One important assumption is that alexithymia severity is associated to vulnerability to somatic diseases, among them gastrointestinal disorders. However, the association between alexithymia and gastrointestinal disorders is not systematic, thus questioning the role of alexithymia as a vulnerability factor for those illnesses. A recent factor analysis sugge…
Psychodiagnostic Assessment of Pathological Gamblers: A Focus on Personality Disorders, Clinical Syndromes and Alexithymia
2015
Comorbid psychopathological syndromes are common in pathological gamblers (PGs), but the contribution of alexithymia, as a disorder of affect regulation, has not been fully explored yet. This study sought to examine the association between personality disorders, clinical syndromes and alexithymia levels in a group of PGs and to highlight a relationship between gambling behaviour and alexithymia scores, apart from the relationship between other disorders and gambling behaviour. Psychological assessment included the South Oaks Gambling Screen, Millon Clinical Multiaxial Inventory (MCMI-III) and Toronto Alexithymia Scale (TAS-20) performed on 70 treatment seeking PGs and 70 healthy controls. S…
The Relationships between Early Trauma, Dissociation, and Alexithymia in Alcohol Addiction
2014
Objective Addiction is often considered a dissociative behavior that is related to alexithymia and developmental trauma. The study aims were to explore the relationships between early trauma, alexithymia, and dissociation. Methods A total of 117 (males=60; females=57) alcohol-addicted individuals and 117 healthy individuals (males=60; females=57) were administered a series of self-report questionnaires that assess traumatic experiences, alexithymia, and pathological dissociation. Results Correlation analyses indicated significant correlations between alexithymia, dissociation, and trauma and a significant difference between the target and control groups, with higher alexithymia and dissocia…
Risk factors for internet gaming disorder in a sample of 5,979 italian online gamers.
2020
Introduction: Online gaming is potentially harmful to a group, but not for the entire population, of online gamers. The prevalence varies by geographical areas, however, there are few Italian studies about risk factors for Internet Gaming Disorder (IGD) and its presence among non-occasional gamers. Objectives: This study aimed to describe the presence of IGD in internet gamers who participate in online communities, and how well-established risk-factors can predict it. Methods: Participants were surveyed about their playing habits and other relevant characteristics. IGDS-SF9 diagnosed IGD. TAS-20 measured alexithymia scores, i.e. Difficult in Identifying (DIF) and Describing Feelings (DDF), …
Relative principal congruences in congruence-modular quasivarieties
1998
The problem of definability of relative principal congruences in relatively congruence modular (RCM) quasivarieties is investigated. The RCM quasivarieties are characterized in terms of parameterized families of finite sets of pairs of terms which define relative principal congruences.
Injectors with a normal complement in a finite solvable group
2011
Abstract Suppose G is a finite solvable group, and H is a subgroup with a normal complement in G. We shall find necessary and sufficient conditions (some of which are related to the properties of coprime actions) for H to be an injector in G. We shall also use these criteria to find characterizations of injectors which need not have a normal complement.
Algebraic and logical characterizations of deterministic linear time classes
1997
In this paper an algebraic characterization of the class DLIN of functions that can be computed in linear time by a deterministic RAM using only numbers of linear size is given. This class was introduced by Grandjean, who showed that it is robust and contains most computational problems that are usually considered to be solvable in deterministic linear time.
Proving convexity preserving properties of interpolatory subdivision schemes through reconstruction operators
2013
We introduce a new approach towards proving convexity preserving properties for interpolatory subdivision schemes. Our approach is based on the relation between subdivision schemes and prediction operators within Harten's framework for multiresolution, and hinges on certain convexity properties of the reconstruction operator associated to prediction. Our results allow us to recover certain known results [10,8,1,7]. In addition, we are able to determine the necessary conditions for convexity preservation of the family of subdivision schemes based on the Hermite interpolation considered in [4].
Improving Interpolants for Linear Arithmetic
2015
Craig interpolation for satisfiability modulo theory formulas have come more into focus for applications of formal verification. In this paper we, introduce a method to reduce the size of linear constraints used in the description of already computed interpolant in the theory of linear arithmetic with respect to the number of linear constraints. We successfully improve interpolants by combining satisfiability modulo theory and linear programming in a local search heuristic. Our experimental results suggest a lower running time and a larger reduction compared to other methods from the literature.
