Many content-based recommendation approaches are based on a dissimilarity measure based on the product attributes. In this paper, we evaluate four dissimilarity measures for product recommendation using an online survey. In this survey, we asked users to specify which products they considered to be relevant recommendations given a reference product. We used microwave ovens as product category. ...

OBJECTIVE To validate a body dissatisfaction scale for adolescents. METHODS The study included 386 female and male adolescents aged 10 to 17 years enrolled in a private elementary and middle school in the city of São Bernardo do Campo, southeastern Brazil, in 2006. 'Escala de Evaluación da Insatisfación Corporal para Adolescentes' (body dissatisfaction scale for adolescents) was translated an...

STUDY DESIGN Prospective study. PURPOSE To evaluate the reliability and validity of the adapted Korean version of the Quality of Life Questionnaire of the European Foundation for Osteoporosis (ECOS-16). OVERVIEW OF LITERATURE The validity of the Korean version of ECOS-16 has not been completely demonstrated. METHODS Translation/retranslation of the English version of ECOS-16, and full cro...

OBJECTIVES To determine the reliability and the content and construct validity of the Mackey Childbirth Satisfaction Rating Scale to measure women's satisfaction with labor and delivery. METHODS The translation-back translation method was used to obtain an adapted version of the scale. For the validation study, a sample of 325 women who had delivered a healthy neonate through the vaginal rout...

We formulate a new class of stochastic partial differential equations (SPDEs), named high-order vector backward SPDEs (B-SPDEs) with jumps, which allow the high-order integral-partial differential operators into both drift and diffusion coefficients. Under certain type of Lipschitz and linear growth conditions, we develop a method to prove the existence and uniqueness of adapted solution to the...

BACKGROUND To develop a culturally adapted and validated Bengali Short Form SF 12v2 among Rheumatoid arthritis (RA) patients. METHODS The English SF 12v2 was translated, adapted and back translated into and from Bengali, pre-tested by 60 patients. The Bengali SF 12v2 was administered twice with 14 days interval to 130 Bangladeshi RA patients. The psychometric properties of the Bengali SF 12v2...

Performance on a visuomotor task in the presence of novel vestibular stimulation was assessed in nine healthy subjects. Four subjects had previously been adapted to 120 min exposure to noisy Galvanic vestibular stimulation (GVS) over 12 weekly sessions of 10 min; the remaining five subjects had never experienced GVS. Subjects were seated in a flight simulator and asked to null the roll motion o...

This paper considers the numerical solution of elliptic boundary value problems with a complicated (nonperiodic) diffusion matrix which is smooth but highly oscillating on very different scales. We study the influence of the scales and amplitudes of these oscillations to the regularity of the solution. We introduce weighted Sobolev norms of integer order, where the (p + 1)st seminorm is weighte...
