Virtual reality in the treatment of claustrophobic fear: A controlled, multiple-baseline design

2000

The aim of this study was to determine the effectiveness of virtual reality (VR) exposure in the treatment of claustrophobic fear. We evaluated the intervention following a controlled, multiple-baseline design across 4 participants with claustrophobic fear who sought psychological help in our anxiety disorders clinic. The treatment consisted of 8 individual VR graded exposure sessions. Data were obtained at pretreatment, posttreatment, and 3-month follow-up on several clinical measures: Behavioral Avoidance Test, Self-Efficacy Toward Closed Spaces, Problem-Related Impairment Questionnaire, Beck Depression Inventory (Beck, 1978), and Anxiety Sensitivity Index (Peterson & Reiss, 1992). Result…

VIII: Statistik in klinischen Publikationen: Checklisten für Autoren

2003

The "Material and Methods" section of clinical research papers should reference major aspects concerning statistical planning and evaluation of the study design and the resulting clinical data. Particular focus is laid on the listing of methods for description and significance evaluation of the trial data, as well as on design-associated study determinants (randomisation and masking strategy, response rate evaluation, primary endpoints, power and sample size determination, multiple testing, software and methods for statistical analysis). Suggestions for the minimum content to be mentioned in a trial publication are listed in author check lists and are illustrated by means of the study synop…

Cognitive impairment in relapsing-remitting multiple sclerosis can be predicted by imaging performed several years earlier.

2007

Cognitive deficits in multiple sclerosis (MS) are common and correlate with contemporary MRI brain abnormalities, particularly atrophy, but the ability of imaging early in the disease to predict later cognitive impairment remains to be determined. Thirty relapsing—remitting MS patients recruited within three years of the onset of the disease, and in whom MRI had been performed at baseline and a year later, were assessed neuropsychologically five years later. Imaging parameters accounting for significant variance in cognitive performance were identified using multiple regressions, once confounding variables were controlled. Patients performed significantly worse than expected on tests of at…

Demonstration Tasks for Assessment

2017

International audience; Learning from animations is conventionally measured using static assessment tools such as multiple choice tests or extended answer questions. These tools tend to rely heavily on textual information both for presenting the assessment items and as the medium for learner response. However, such assessments are not well aligned with the defining dynamic, pictorial characteristics of animated learning materials. This chapter considers the potential of demonstration tasks to offer more appropriate assessments of learning from animation. In these tasks, learners interact with a manipulable model of the animation’s subject matter to provide an explanatory account of how it c…

Spatial information transmission using orthogonal mutual coherence coding.

2005

We use the coherence of a light beam to encode spatial information. We apply this principle to obtain spatial superresolution in a limited aperture system. The method is based on shaping the mutual intensity function of the illumination beam in a set of orthogonal distributions, each one carrying the information for a different frequency bandpass or spatial region of the input object. The coherence coding is analogous to time multiplexing but with multiplexing time slots that are given by the coherence time of the illumination beam. Most images are static during times much longer than this coherence time, and thus the increase of resolution in our system is obtained without any noticeable c…

An interactive approach to multiple criteria optimization with multiple decision-makers

1986

In this article we propose a formal man-machine interactive approach to multiple criteria optimization with multiple decision makers. The approach is based on some of our earlier research findings in multiple criteria decision making. A discrete decision space is assumed. The same framework may readily be used for multiple criteria mathematical programming problems. To test the approach two experiments were conducted using undergraduate Business School students as subjects in Finland and in the United States. The context was, respectively, a high-level Finnish labor-management problem and the management-union collective bargaining game developed at the Krannert Graduate School of Management…

Successful control of an outbreak of colonization by Klebsiella pneumoniae carbapenemase-producing K. pneumoniae sequence type 258 in a neonatal inte…

2013

This article reports an outbreak of colonization by Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) sequence type (ST) 258 in a neonatal intensive care unit (NICU) in Palermo, Italy. KPC-Kp ST258 was detected by an active surveillance culture programme. Between 18th September and 14th November 2012, KPC-Kp was isolated from 10 out of 54 neonates admitted in the outbreak period. No cases of infection were recorded. Male sex was associated with colonization, whereas administration of ampicilline-sulbactam plus gentamicin was protective. Infection control interventions interrupted the spread of KPC-Kp without the need to close the NICU to new admissions. (C) 2013 The Healt…

A longitudinal examination of the transition to symbolic communication in the second year of life

2003

Between 10 and 24 months of age, children progress from communicating through conventional signals to communicating through symbols in a variety of situations. The present study investigates this transition analysing mother–child communication frames and the child’s communicative acts, and tracing the developmental changes in both frames and communicative acts. Four children (2 girls, 2 boys) and their mothers were observed longitudinally and extensively, from 10 to 24 months of age, using a multiple case-study method. Through the detailed investigation of these single cases, clear developmental trajectories were found, showing that conventional frames and representational gestures ‘bridge’…

Exon deletions of the PAH gene in Italian hyperphenylalaninemics

2010

A consistent finding of many studies describing the spectrum of mutant phenylalanine hydroxylase alleles underlying hyperphenylalaninemia is the impossibility of achieving a 100% mutation ascertainment rate using conventional gene-scanning methods such as Denaturing Gradient Gel Electrophoresis (DGGE), Denaturing High Performance Liquid Chromatography (DHPLC), direct sequencing. In recent years, it has been shown that a significant proportion of these undetermined alleles consist of large deletions overlapping one or more exons. These deletions have been difficult to detect in compound heterozygotes by gene-scanning methods due to the masking effect by the non-deleted allele. To date no sys…
