Associations Between Interpersonal Problems, Negative Affect, and Symptoms of Night Eating Syndrome

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Research on social support, attachment insecurity, and negative affect in night eating syndrome (NES) is sparse, although these factors have been proposed as key components of etiological models in other eating disorders. This study investigated whether individuals with night eating (NE) symptoms reported lower social support ...

Virtual (Self) Reflection: Frequent Videoconferencing Usage Is Uniquely Associated With Body Dissatisfaction and Dietary Restraint Symptoms Among Adults

European Eating Disorders Review, EarlyView.
ABSTRACT Objective This study examined the relationship between videoconferencing usage frequency for work/study purposes and eating disorder (ED)‐related symptoms, focusing on psychological factors that may heighten vulnerability to such concerns in appearance‐focused interactions.

A transference result of the $L^p$ continuity of the Jacobi Riesz transform to the Gaussian and Laguerre Riesz transforms [PDF]

, 2012
In this paper using the well known asymptotic relations between Jacobi polynomials and Hermite and Laguerre polynomials. We develop a transference method to obtain the $L^p$-continuity of the Gaussian-Riesz transform and the $L^p$-continuity of the ...

Mixed Fourier–Jacobi spectral method [PDF]

Journal of Mathematical Analysis and Applications, 2006
This paper is for mixed Fourier–Jacobi approximation and its applications to numerical solutions of semiperiodic singular problems, semi-periodic problems on unbounded domains and axisymmetric domains, and exterior problems. The stability and convergence of proposed spectral schemes are proved.

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

Journal of Quaternary Science, EarlyView.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Three‐Week Video‐ and Home‐Based Training Program for People with Ataxia: A Pilot Randomized Controlled Trial

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Gait and balance impairment is a disabling clinical feature in people with degenerative cerebellar ataxia. Objectives We performed a rater‐blinded, parallel 3‐arm randomized controlled trial with delayed‐start‐design (exploratory proof‐of‐concept study) to assess whether, compared to control, people with mild/moderate hereditary ...

Mixed Jacobi-Fourier spectral method for Fisher equation

Mathematical Modelling and Analysis, 2018
In this paper, we propose a mixed Jacobi-Fourier spectral method for solving the Fisher equation in a disc. Some mixed Jacobi-Fourier approximation results are established, which play important roles in numerical simulation of various problems defined in ...
