La influencia de la distancia al mar en la distribución de la flora de las dunas del Cabo de Gata

1989

Se realiza un estudio de la distribución respecto de la distancia al mar de las especies presentes en una porción de la franja arenosa del Cabo de Gata (Almería, España). La distancia al mar ha resultado ser un factor decisivo cuya influencia sobre otros factores ambientales -microrrelieve- ha sido revelada por la interpretación de la ordenación establecida por el Análisis Factorial de Correspondencias efectuado sobre los datos de los valores de cobertura de Ias especies en los inventarios de los intervalos de distancia considerados. A species distribution study in relation to the sea distance is realized in a portion of the sandy strip from "Cabo de Gata" (Almeria, Spain). The sea distance…

Chen’s iterated integral represents the operator product expansion

1999

The recently discovered formalism underlying renormalization theory, the Hopf algebra of rooted trees, allows to generalize Chen’s lemma. In its generalized form it describes the change of a scale in Green functions, and hence relates to the operator product expansion. Hand in hand with this generalization goes the generalization of the ordinary factorial n! to the tree factorial t. Various identities on tree-factorials are derived which clarify the relation between Connes-Moscovici weights and Quantum Field Theory.

Evidence, and replication thereof, that molecular-genetic and environmental risks for psychosis impact through an affective pathway

2022

AbstractBackgroundThere is evidence that environmental and genetic risk factors for schizophrenia spectrum disorders are transdiagnostic and mediated in part through a generic pathway of affective dysregulation.MethodsWe analysed to what degree the impact of schizophrenia polygenic risk (PRS-SZ) and childhood adversity (CA) on psychosis outcomes was contingent on co-presence of affective dysregulation, defined as significant depressive symptoms, in (i) NEMESIS-2 (n = 6646), a representative general population sample, interviewed four times over nine years and (ii) EUGEI (n = 4068) a sample of patients with schizophrenia spectrum disorder, the siblings of these patients and controls.ResultsT…

Socialização parental: adaptação ao Brasil da escala ESPA29

2011

The objective of this study was to analyze the psychometric properties of the Brazilian version of the ESPA29 Parental Socialization Scale (Musitu & Garcia, 2001). This scale allows measuring parental styles - authoritative, authoritarian, indulgent, and negligent - by means of two independent dimensions of parental conduct extracted from parents' use of different socialization practices. Using a sample of 2.105 Brazilian adolescents from 10 to 18 years old, the structure of two factors that define the scale - Acceptance/Implication and Strictness/Imposition - has been replicated using an exploratory factorial analysis. In order to complete a proper replication of the ESPA29 scale structure…

Validation of the Marathon Motivation Scale in Chile

2021

The objective of this work was to validate the Marathon Motivation Scale (MOMS) for its application in the Chilean context. The study used a non-experimental, descriptive and transversal design. The sample was non-probability and intentional and was composed of 250 subjects (143 male and 104 female) runners who participated in the International Marathon of Viña del Mar with an average age of 29.8 (TD = 10.1) years. For the analysis of the data, an exploratory factorial analysis was carried out with free parameters, another one with seven factors fixed to the theoretical dimensions and a confirmatory factorial analysis with the items corresponding to the MOMS model. The validity and reliabil…

The Italian version of the Cognitive Style Indicator and its association with decision-making preferences

2018

By adopting a more flexible view, Cools and Van den Broeck (2007) developed the Cognitive Style Indicator (CoSI) which includes three cognitive dimensions: Creating (flexible, open-ended and inventive), Knowing (emphasizing facts, details, objectivity, and rationality), and Planning (guided by preferences for certainty and well-structured information). The first aim of this research was to validate the three factor structure of the CoSI within the Italian context, whereas the second was to verify whether cognitive styles, as measured by the CoSI, accounted for individual differences in decision-making processes. Two studies were conducted using two different samples (n = 549 and n = 397). C…

The Reciprocal Influences among Motivation, Personality Traits, and Game Habits for Playing Pokémon GO

2018

This article reports a study exploring motivations of Pokémon Game use, individual differences related to personality traits, and game habits. First, it analyzed Pokémon GO motivations through exploratory factor analysis (EFA) by administering online the Pokémon GO Motivational Scale to a group of Italian gamers (N = 560). Successively, a Confirmatory Factor Analysis (CFA) was conducted testing three factorial models of Pokémon Game motivations on a selected random sample (N = 310). Results showed a three-factor model of Pokémon GO Game motivations (i.e. Personal Needs, Social Needs and Recreation), accounting for 68.9% of total variance plus a general higher order factor that best fits the…

2018

Data presented in this article are supplementary material to our article entitled "Identification and diagnosis of patients with familial chylomicronaemia syndrome (FCS): expert panel recom mendations and proposal of an "FCS Score" (Moulin et al., 2018, in press). The data describe the genotypes of patients with familial chylomicronaemia syndrome (FCS) and multifactorial chylomicro naemia syndrome (MCS), from the validation and replication cohorts.
