Prevalence of fatigue in Parkinson disease and its clinical correlates
2014
Objective: To assess in a noninterventional setting the prevalence and severity of fatigue in patients with Parkinson disease (PD). Methods: This was a cross-sectional study conducted in Italian patients with PD. Objectives included the evaluation of the current prevalence and severity of fatigue in patients with PD measured using the 16-item Parkinson Fatigue Scale (PFS-16), distressing fatigue (defined as a PFS-16 mean score $3.3), and assessment of its clinical correlates. Results: A total of 402 patients were enrolled and 394 patients completed the PFS-16 questionnaire with a PFS-16 mean (6SD) score of 2.87 6 0.99. Of these, 136 patients (33.8%) reported distressing fatigue (PFS-16 mean…
Measuring patient experiences in Fabry disease: validation of the Fabry-specific Pediatric Health and Pain Questionnaire (FPHPQ)
2012
Abstract Introduction Common symptoms for children with Anderson-Fabry Disease (FD) such as acroparaesthesia and gastrointestinal manifestations can only be objectively assessed in patients using a valid instrument. To date, no such instrument exists. Methods A preliminary 40-item measure of symptoms and experience with FD, the Fabry-specific Paediatric Health and Pain Questionnaire (FPHPQ) was developed, but lacked a formal assessment of its measurement properties. The FPHPQ was used in the Fabry Outcome Survey (FOS), a registry for all patients with a confirmed diagnosis of FD who are receiving agalsidase alfa, or are treatment naïve and who are managed by physicians participating in FOS.…
Polycitemia vera and pulmonary embolism: case report
2013
Pulmonary embolism is a rare clinical onset of chronic myeloproliferative diseases. Early diagnosis is very important because medical therapy reduces both mortality and morbility. We describe a case of pulmonary embolism as clinical onset of an unknown myeloproliferative disorder. On the basis of our experience is very important early diagnosis and therapy to reduce incidence of later major thrombotic complications.
Evaluating multidimensional prices
1998
The price at which a product is offered often does not consist of a single item of information, for example VW Golf, price; DM25,476. Instead, a multidimensional pricing system is used, e.g. the price comprises a down payment, monthly installments and a repayment period in months. Despite the considerable significance of offers of this type for marketing policy, no information is presently available to describe how a consumer integrates the individual price dimensions (e.g. down payment, monthly installments and number of repayment periods) to form a global judgment. This article derives hypotheses to explain the formation of a price judgment about multidimensional prices. Then, an empirica…
Multitemporal Cloud Masking in the Google Earth Engine
2018
The exploitation of Earth observation satellite images acquired by optical instruments requires an automatic and accurate cloud detection. Multitemporal approaches to cloud detection are usually more powerful than their single scene counterparts since the presence of clouds varies greatly from one acquisition to another whereas surface can be assumed stationary in a broad sense. However, two practical limitations usually hamper their operational use: the access to the complete satellite image archive and the required computational power. This work presents a cloud detection and removal methodology implemented in the Google Earth Engine (GEE) cloud computing platform in order to meet these r…
Real time polarization imaging of weld pool surface
2015
The search for an efficient on-line monitoring system focused on the real-time analysis of arc welding quality is an active area of research. The topography and the superficial temperature field of the weld pool can provide important information which can be used to regulate the welding parameters for depositing consistent welds. One difficulty relies on accessing this information despite the bright dazzling welding arc. In the present work, Stokes polarimetry and associated shape-from-polarization methods are applied for the analysis of the weld pool through its 810 nm-wavelength infrared emissions. The obtained information can provide a better understanding of the process, such as the usa…
Les chiffres : les comprendre pour s'en dépendre
2011
C'est le regard d'une sociologue qualitativiste qui a fait l'objet de cette conférence invitée. D'un forum qui replaçait au centre des débats l'éthique et le vivre-ensemble, mais inscrit dans un atelier sur "les nombres", l'intervention d'un chercheur qualitativiste, aux côtés d'un mathématicien Thierry Duchesne (Université Laval) et de la démographe Chantal Girard (ISQ - Institut de la statistique du Québec), a fait figure de contre-emploi. La communication s'est centrée sur la remise en question de l'universalité du nombre : le nombre, dans son rapport à l'écrit est-il un sociocentrisme ? Cet universalisme supposé peut également être débattu au regard de l'usage historique du nombre (de l…
Psychometric Properties of an Emotional Adjustment Measure
2007
Item response theory (IRT) provides valuable methods for the analysis of the psychometric properties of a psychological measure. However, IRT has been mainly used for assessing achievements and ability rather than personality factors. This paper presents an application of the IRT to a personality measure. Thus, the psychometric properties of a new emotional adjustment measure that consists of a 28-six graded response items is shown. Classical test theory (CTT) analyses as well as IRT analyses are carried out. Samejima's (1969) graded-response model has been used for estimating item parameters. Results show that the bank of items fulfills model assumptions and fits the data reasonably well,…
A Short Measure of Acceptability of Intimate Partner Violence Against Women: Development and Validation of the A-IPVAW-8 Scale
2021
Attitudes of acceptability of intimate partner violence against women (IPVAW) are considered one of the main risk factors of this type of violence. The aim of this study is to develop and validate a short version of the acceptability of IPVAW scale, the A-IPVAW-8, for large scale studies where space and time are limited. A panel of experts were asked to assess item content validity. Two samples were recruited to assemble an 8-item short version of the scale using automated test assembly, and to reassess the psychometric properties of the A-IPVAW-8 in an independent sample. Results showed that the A-IPVAW-8 had adequate internal consistency (α = .72-.76, ω = .73-.81), a stable one-factor la…
