Propiedades psicométricas del Inventario Breve de Síntomas-18 en una muestra heterogénea de pacientes de cáncer adulto
2019
espanolResumen El Inventario Breve de Sintomas-18 (BSI-18) es un instrumento de cribado ampliamente utilizado para evaluar distres emocional (GSI) y tres tipos de sintomas: ansiedad, depresion, y somatizacion. Este trabajo estudia la estructura factorial del BSI-18, utilizando analisis factorial confirmatorio (AFC), su fiabilidad y validez convergente, asi como su invarianza factorial a traves del sexo. Una muestra de 1183 pacientes de cancer completo el BSI 18 y la lista de problemas de la NCCN. Los modelos jerarquicos de tres y cuatro factores proporcionaron ajustes adecuados y similares. Sin embargo, el modelo de tres factores (propuesta teorica) fue seleccionado por razones metodologica…
Quality-based assessment of camera navigation skills for laparoscopic fundoplication.
2020
Summary Laparoscopic fundoplication is considered the gold standard surgical procedure for the treatment of symptomatic hiatus hernia. Studies on surgical performance in minimally invasive hiatus hernia repair have neglected the role of the camera assistant so far. The current study was designed to assess the applicability of the structured assessment of laparoscopic assistance skills (SALAS) score to laparoscopic fundoplication as an advanced and commonly performed laparoscopic upper GI procedure. Randomly selected laparoscopic fundoplications (n = 20) at a single institute were evaluated. Four trained reviewers independently assigned SALAS scoring based on synchronized video and voice rec…
Theory of ground state factorization in quantum cooperative systems.
2008
We introduce a general analytic approach to the study of factorization points and factorized ground states in quantum cooperative systems. The method allows to determine rigorously existence, location, and exact form of separable ground states in a large variety of, generally non-exactly solvable, spin models belonging to different universality classes. The theory applies to translationally invariant systems, irrespective of spatial dimensionality, and for spin-spin interactions of arbitrary range.
Integrating the Analysis of Mental Operations Into Multilevel Models to Validate an Assessment of Higher Education Students’ Competency in Business a…
2016
The Standards for Educational and Psychological Testing indicate that validation of assessments should include analyses of participants’ response processes. However, such analyses typically are conducted only to supplement quantitative field studies with qualitative data, and seldom are such data connected to quantitative data on student or item performance. This paper presents an example of how data from an analysis of mental operations collected using a sociocognitive approach can be quantitatively integrated with other data on student and item performance to validate in part an assessment of higher education students’ competency in business and economics. Evidence of forward reasoning an…
Psychometric properties of saving cognition inventory in Italian nonclinical samples
2020
The main purpose of the study was aimed to examine the psychometric properties of the Saving Cognition Inventory (SCI) in Italian nonclinical samples. Two studies were conducted: (a) study 1 was focused on the confirmation of the factorial structure, internal consistency reliability, and subscales' intercorrelations on a sample of 252 participants; (b) study 2 was focused on gathering construct validity data on a sample of 244 participants. In addition to the SCI, other seven self-report measures were administered in order to assess hoarding, depression, anxiety, and obsessive compulsive disorder symptoms. Our results supported the hypothesis of four adequately reliable dimensions. Support …
The Primary Care Evaluation of Mental Disorders (PRIME-MD), German version: a comparison with the CIDI
2000
There is a need for the development and evaluation of diagnostic instruments suitable for daily use in primary care offices that can improve recognition rates of psychopathology. The objective of this study is the comparison of the German version of the Primary Care Evaluation of Mental Disorders (PRIME-MD), a short structured diagnostic instrument, with the Composite International Diagnostic Interview (CIDI) and to gather some information on the usefulness of the PRIME-MD. Seven hundred and four patients were assessed three times, once using the physician's clinical judgement, subsequently, administering the PRIME-MD, DSM-IV version and finally, with the CIDI. The CIDI was administered on …
Problemi di giurisdizione nel contrasto al traffico di migranti via mare
2018
I trafficanti di esseri umani si avvalgono con sempre più insistenza di ben collaudati protocolli operativi. Questi ultimi consentono loro di sottrarsi alla giurisdizione penale italiana che non si radica qualora – in ossequio ai criteri di cui all’art. 6 c.p.ed in conformità alla Convenzione sull’Alto Mare– l’azione illecita avvenga in acque internazionali.Così, premesse alcune linee concettuali sui limiti spaziali alla efficacia della legge penale, l’indagine si sofferma sulla soluzione ermeneutica offerta dallaCassazione che, apparentemente in modo sbrigativo e per esigenze di effettività della risposta punitiva, ha fatto ricorso alla controversa figura dell’autore mediato per sanzionare condott…
Intuitive eating: A novel eating style? Evidence from a Spanish sample
2020
Contains fulltext : 217000.pdf (Publisher’s version ) (Closed access) Intuitive eating is defined as an adaptive way of eating that maintains a strong connection with the internal physiological signs of hunger and satiety. It has four elements: unconditional permission to eat whenever and whatever food is desired, eating for physical rather than for emotional reasons, reliance on hunger and satiety cues to determine when and how much to eat, and body-food choice congruence. In this study, we assessed the differences and similarities between intuitive eating, as measured with the Intuitive Eating Scale-2, and eating styles (restrained, emotional, and external eating), as assessed with the Du…
PO-CALC: A novel tool to correct common inconsistencies in the measurement of phenoloxidase activity
2015
Abstract A broad range of physiological and evolutionarily studies requires standard and robust methods to assess the strength and activity of an individual’s immune defense. In insects, this goal is generally reached by spectrophotometrically measuring (pro-) phenoloxidase activity, an enzymatic and non-specific process activated after wounding and parasite infections. However, the literature surprisingly lacks a standard method to calculate these values from spectrophotometer data and thus to be able to compare results across studies. In this study, we demonstrated that nine methods commonly used to extract phenoloxidase activities (1) provide inconsistent results when tested on the same …
Tourism-led growth hypothesis in the top ten tourist destinations: New evidence using the quantile-on-quantile approach
2017
This paper examines the empirical validity of the tourism-led growth hypothesis in the top ten tourist destinations in the world (China, France, Germany, Italy, Mexico, Russia, Spain, Turkey, the United Kingdom, and the United States) using the quantile-on-quantile (QQ) approach and a new index of tourism activity that combines the most commonly used tourism indicators. This methodology, recently introduced by Sim and Zhou (2015), provides an ideal framework with which to capture the overall dependence structure between tourism development and economic growth. The empirical results primarily show a positive relation between tourism and economic growth for the ten countries considered with s…
