Psychometric analysis of the Test of Dependence of Videogames (TDV) in Peruvian population
2017
Resumen El objetivo del presente trabajo es validar en población peruana, el Test de Dependencia de Videojuegos (TDV) (Chóliz & Marco, 2011). Los resultados obtenidos demuestran que se trata de una herramienta confiable y válida. Se encontró una sola estructura factorial, en lugar de cuatro dimensiones, como plantearon los autores del TDV. Este factor podría denominarse genéricamente: adicción a videojuegos, y podría servir como evidencia de la existencia de este trastorno, que coincidiría con el denominado ‘Trastorno de Juego por Internet’, que aparece en la Sección III del DSM-5. Los resultados hallados se discuten en relación a lo planteado por Chóliz y Marco (2011), en lo que se refiere…
Distinctive attributes for predicted secondary structures at terminal sequences of non-classically secreted proteins from proteobacteria
2008
Abstract C- and N-terminal sequences (64 amino acid residues each) of 89 non-classically secreted type I, type III and type IV proteins (Swiss-Prot/TrEMBL) from proteobacteria were transformed into predicted secondary structures. Multivariate analysis of variance (MANOVA) confirmed the significance of location (C- or N-termini) and secretion type as essential factors in respect of quantitative representations of structured (a-helices, b-strands) and unstructured (coils) elements. The profiles of secondary structures were transcripted using unequal property values for helices, strands and coils and corresponding numerical vectors (independent variables) were subjected to multiple discriminan…
An Autonomous System to Take Angular Thermal-Infrared Measurements for Validating Satellite Products
2015
An autonomous system for field land surface temperature (LST) measurements taken at different observation angles was developed to be deployed easily at any conventional meteorological tower station. The system permits ground-truth data to be acquired on a continuous basis, and angularly scans land and sky hemispheres with a single thermal-infrared (TIR) radiometer. This paper describes the autonomous angular system and the methodology to assess ground-truth LST and relative-to-nadir emissivity data from system measurements. Ground-truth LSTs were used to validate satellite-retrieved LST products at two experimental sites (rice crop and shrubland areas). The relative-to-nadir emissivity valu…
Validācijas principa piemērošana, nosakot starptautiskam šķīrējtiesas līgumam piemērojamo likumu
2022
Lai nodrošinātu starptautiskajam šķīrējtiesas procesam labvēlīgu nacionālu vidi, ir attīstīta īpaša kolīziju norma – validācijas princips. Validācijas princips paredz: ja lietā ir potenciāli piemērojami vairāki likumi, validācijas princips uzliek tiesai vai šķīrējtiesai pienākumu piemērot likumu, kurš nodrošina šķīrējtiesas līguma spēkā esamību. Par spīti validācijas principa plašai piemērošanai starptautiskajā doktrīna un praksē, Latvijas tiesību sistēmā šāda kolīziju norma vēl netiek piemērota. Tādēļ pētījuma mērķis ir attīstīt validācijas principa kā kolīziju normas piemērošanas shēmu, ko piemērot tribunālu un tiesu praksē, tajā skaitā Latvijā. Darba uzdevumi ir (1) izpētīt validācijas p…
The Utrecht-Management of Identity Commitments Scale (U-MICS)
2021
Abstract. The current study proposed the adaptation of the Utrecht-Management of Identity Commitments Scale (U-MICS) to the religious domain as an instrument to measure both individuals’ religious identity formation processes (when a variable-centered approach is adopted) and religious identity statuses (when a person-centered approach is adopted). The scale has been tested on a sample of 727 Italian participants aged 13–65 years, by collecting evidence of score structure, convergent, and criterion-related validity. Regarding the score structure validity, we confirmed that religious identity formation consists of three processes (commitment, in-depth exploration, reconsideration of commitm…
Resilience and the Aging Process: Assessment Tools and Needs
2015
Abstract Successful resilience is a variable often related to an optimal aging process and that might have a role on education. However, literature is rather limited when dealing with assessment instruments for the elderly in the Spanish language. The objective of this work is to examine the Brief Resilient Coping Scale (Sinclair &Wallston, 2004), a four item likert scale, in the Spanish elderly. This scale was administrated to a sample of 920 elderly Spanish participants, and the data set analysed in terms of exploratory and confirmatory factor analysis and internal consistency. The scale demonstrated good psychometric properties. Furthermore, the homogeneity indices were higher than in th…
Temperament and personality: the German version of the Adult Temperament Questionnaire (ATQ)
2006
The psychobiological orientation inherent in temperament concepts permits a close tie between temperament and the rapidly proliferating research areas of neurosciences and behavioural genetics. Based on developmental and psychobiological studies, the Adult Temperament Questionnaire (ATQ) by Rothbart measures self-regulatory processes in addition to constitutionally based individual reactivity. The purpose of this paper is to validate a German version of the short form of the ATQ with 77 items. 213 psychosomatic inpatients and outpatients and 116 control subjects took part in this study. The study included standardized measures of personality and symptoms. The German version reliably measure…
The structural validity of the Finnish version of the Disabilities of the Arm, Shoulder and Hand : a Rasch model analysis
2020
Abstract Introduction: The construct validity of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) has previously been questioned. The purpose of this study was to evaluate the measurement properties of the Finnish version of the DASH for assessing disability in patients with hand complaints using Rasch Measurement Theory. Methods: A cohort of 193 patients with typical hand and wrist complaints were recruited at a surgery outpatient clinic. The DASH scores were analysed using the Rasch model for differential item functioning, unidimensionality, fit statistics, item residual correlation, coverage/targeting and reliability. Results: In the original DASH questionnaire, the it…
A New Academic Quality at Work Tool (AQ@workT) to Assess the Quality of Life at Work in the Italian Academic Context
2022
Refereed/Peer-reviewed The present study provides evidence for a valid and reliable tool, the Academic Quality at Work Tool (AQ@workT), to investigate the quality of life at work in academics within the Italian university sector. The AQ@workT was developed by the QoL@Work research team, namely a group of expert academics in the field of work and organizational psychology affiliated with the Italian Association of Psychologists. The tool is grounded in the job demands-resources model and its psychometric properties were assessed in three studies comprising a wide sample of lecturers, researchers, and professors: a pilot study (N = 120), a calibration study (N = 1084), and a validation study …
