Principal component analysis (PCA) is one of the most important and powerful methods in chemometrics as well as in a wealth of other areas. Running a PCA results in two main elements, the score plot and the loading plot; the score plot provides the location of the samples, and the loading plot indicates correlations among variables, the trends in…

Purpose: This study was intended to adapt into Spanish and validate the short form of the Marwit-Meuser Caregiver Grief Inventory (MMCGI), an instrument for the assessment of levels of grief in caregivers of patients with dementia. Method: The adaptation was based on the cross-cultural equivalence model that included forward and backward…

Purpose of the study: Studies have shown that patient safety culture (PSC) is poorly developed in nursing homes (NHs), and, therefore, residents of NHs may be at risk of harm. Using Donabedian's Structure-Process-Outcome (SPO) model, we examined the relationships among top management's ratings of NH PSC, a process of care, and safety outcomes.…

The CORFIS ("Community-Based Cardiovascular Risk Factors Intervention Strategies") program was piloted in community clinics in Malaysia to address the lack of health education in chronic disease management. The stages of change model was applied in a multicenter quasi-experimental design to evaluate adherence to advocated behaviors in…

A theoretical framework which considers the verbal functions of the brain under a multivariate and comprehensive cognitive model was statistically analyzed. A confirmatory factor analysis was performed to verify whether some recognized aphasia constructs can be hierarchically integrated as latent factors from a homogenously verbal test. The Brief…

Letter recognition is the foundation of the human reading system. Despite this, it tends to receive little attention in computational modelling of single word reading. Here we present a model that can be trained to recognise letters in various spatial transformations. When presented with degraded stimuli the model makes letter confusion errors…

Despite the existence of speech errors, verbal communication is successful because speakers can detect (and correct) their errors. The standard theory of speech-error detection, the perceptual-loop account, posits that the comprehension system monitors production output for errors. Such a comprehension-based monitor, however, cannot explain the…

Purpose: To assess the association between Veterans Affairs (VA) stroke patients' poststroke rehabilitation utilization and their residential settings by using 2 common rural-urban taxonomies. Methods: This retrospective study included all VA stroke inpatients in 2001 and 2002. Rehabilitation utilization referred to rehabilitation therapy received…

A role for the cerebellum in cognition has been proposed based on studies suggesting a profile of cognitive deficits due to cerebellar stroke. Such studies are limited in the determination of the detailed organisation of cerebellar subregions that are critical for different aspects of cognition. In this study we examined the correlation between…

Junior doctors are at risk of work-related burnout and mental health problems due to training workload demands and responsibilities. This study investigated the predictors of work-related burnout and depressive symptoms in junior doctors. Participants were 349 Australian doctors in postgraduate years 1-4, who completed a web-based survey assessing…

Stroke is the second leading cause of death and a major cause of adult disability in Taiwan. This research established correlations between pre-admission and discharge data in stroke patients to promote education of the general public, prevention, treatment and high standards of chronic care. A total of 790 stroke patients at Chung Shan Medical…

A word-length effect is often described in pure alexia, with reading time proportional to the number of letters in a word. Given the frequent association of right hemianopia with pure alexia, it is uncertain whether and how much of the word-length effect may be attributable to the hemifield loss. To isolate the contribution of the visual field…

The nature of the alliance-outcome relationship is still emerging. This study examined the reciprocal influence of change in alliance to the group and change in urge to restrict in eating-disordered individuals attending a group-based day treatment. Participants (N = 238) were a transdiagnostic or mixed diagnostic sample of eating-disordered…

Narrative discourse is an essential component of day-to-day communication, but little is known about narrative in Lewy body spectrum disorder (LBSD), including Parkinson's disease (PD), Parkinson's disease with dementia (PDD), and dementia with Lewy bodies (DLB). We performed a detailed analysis of a semi-structured speech sample in 32 non-aphasic…

Theoretical models of addiction suggest that attentional bias for substance-related cues should be associated with self-reported craving. The authors evaluated the strength of the association by performing a meta-analysis on 68 independent data sets from which correlation coefficients between subjective craving and attentional bias indices were…
