Value-based benefits design research high-level findings
No full text[Report] -- Attachment A. Methodology -- Attachment B. Presentation Slides.prepared for: Portland State University & Office for Oregon Health Policy & Research ; by Carol Foley, Ph.D.Title from PDF cover (viewed on April 16, 2020)."During a period from late September to mid-October of 2010, a series of research forums were conducted to get feedback from those impacted by a value-based benefits design; the benefit design is intended for employers and individual purchasers in an Oregon health exchange. Insurers, agents/brokers, hospitals, providers, employers, consumers, and consumer advocates participated in the forums"--Page 2.This archived document is maintained by the State Library of Oregon as part of the Oregon Documents Depository Program.

Anxiety in Parkinson's: what do we know, what can we learn from research, and practical tips for dealing with the problem. [Podcast]
No full textWelcome to part 1 of our special two-part podcast to mark World Mental Health Day 2023 on the 10th October. Julie Jones and Neil Morrison from NoSPRIG are joined by Senior Clinical Neuropsychologist Dr Jennifer Foley and mental health specialist Parkinson's Nurse Emma Edwards. In this first episode, we take an in-depth look at anxiety - one of the most common mental health issues facing people with Parkinson's
Contribution of Executive Functions and Dual-Tasking on Performance on the Edinburgh Virtual Errands Tests (EVET): An Individual Difference Study
No full textThis individual differences study reports the role of Executive Function tests of Shifting, Updating and Inhibition, as well as Dual-Tasking and IQ on performance within the Edinburgh Virtual Errands Test (EVET). 62 healthy young adults between 18-35 where tested in this study. The stimulus used in this study was Dual-Tasking (Della Sala, Foley, Beschin, Allerhand, & Logie, 2010), EVET (Logie, Trawley, & Law, 2010), DKEFS Category Switching, DKEFS Color-Word Interference, Letter Number Sequencing (Wechsler Adult Intelligence Scale), and the National Adult Reading Test (Nelson, 1982). A significant correlation was found between Dual-Tasking and Inhibition, although no other significant correlations where found between the variables. Regression analysis revealed that Inhibition accounted for 5.5% of the variance in performance on the EVET. Further post-hoc analysis was conducted to examine the unexplained variance. Regression analysis revealed that Memory and Processing Speed accounted for 41.5% of the variance within the EVET

Ececutive Functions in Multi-tasking: Two, not four, evidenced in complex behaviours
No full textTraditional neuropsychological or ‘frontal’ tests often fail to reveal deficits of people exhibiting dysexecutive behaviours. Every-day multi-tasking is problematic and thought to relate to deficits in non-domain-specific executive functions (EFs). Miyake et al (2000), through systematic testing, developed a model of EFs: shifting, inhibition, updating and dual-tasking. Dual-tasking is reliably shown to be diminished in participants with every-day problems. This study aimed to show that dual-tasking was predictive of multi-tasking. Paper-and-pencil tests provided measures of EF and intelligence and multi-tasking ability was measured using the Edinburgh, Virtual Errands Test (EVET). Correlations between primary measures were non-significant except between ‘inhibition’ and ‘dual-tasking’. Contrary to hypothesis, dual-tasking was not found to be a significant predictor of multi-tasking. Exploratory analyses revealed relationships in component measures, particularly with an unadjusted measure of inhibition. The ‘supervisory system’ (Shallice & Burgess, 2006) was used as a framework to discuss findings, as well as research into activations in the anterior cingulate cortex (ACC) and dorsolateral prefrontal cortex (DLPFC) during inhibitory processing. The study concluded that EFs of ‘inhibition’ and ‘shifting’ were involved in the specification and later implementation of stimulus-response intentions but depend on interaction with monitoring processes in the ACC. ‘Updating’ was proposed to be representative of working memory and ‘dual-tasking’ was proposed to reflect successful strategy application to enable the monitoring of two independent behaviours without need of EF input. Deficits in dual-tasking are proposed to be a failure to impose the necessary monitoring criteria
Microsecond resolution of cavitation bubble dynamics using a high-speed electrochemical impedance approach
No full textA new method to detect the uncompensated resistance, the capacitance and the Faradaic current at an electrode exposed to ultrasonic cavitation is presented. The method enables these parameters to be resolved with a 2 microsecond resolution and relies on the detection of the impedance of an electrode recorded as a function of time with a suitable AC excitation signal (here 500 kHz). Data obtained from an aluminium electrode, held under potentiostatic control, is used to illustrate the technique with particular relevance to the effects of cavitation bubbles generated by ultrasound. Analysis of the data recorded shows that the cavitation bubbles form close to the surface of the electrode and collapse, causing damage to the passive film formed at the aluminium surface. The capacitance, uncompensated resistance and Faradaic signals are used to explore the dynamic processes and show expansion and collapse of bubbles prior to erosion/corrosion. The close proximity of the bubbles to the surface is deduced from the reductions in capacitance and increases in resistance prior to bubble collapse, which is then shown to trigger the onset of a Faradaic signal, thus confirming the erosion/corrosion mechanism previously assumed
Executive Functioning and Social Behaviour: How Are They Related and How Does This Change With Age?
No full textExecutive functions, such as inhibition and dual tasking, have repeatedly been linked to social behaviour (e.g. McDonald & Pearce, 1996; Foley, Cantagallo, Della Sala & Logie, 2010); however the exact strength and nature of this relationship is still unknown. Although certain executive functions, such as dual tasking, are maintained at a high-level into old age (e.g. Logie, Cocchini, Della Sala & Baddeley, 2004) others, such as inhibition, have repeatedly been shown to decline with age (e.g. Wecker, Kramer, Wisniewski, Delis & Kaplan, 2000). It has been suggested these changes in executive function ability may mediate some of the social-behavioural changes we see with age (e.g. Henry, von Hippel & Baynes, 2009).
This study aimed to investigate the relationship between executive and social functioning and further to this, how changes of executive performance with age may contribute to changing social performance. The study focusses on inhibition and dual-tasking as executive functions and assesses social ability via an emotion recognition test and a social inference test. Performance on a battery of social and executive tests was measured in both a younger (N=48) and older age group (N=48).
Younger adults were found to outperform older adults on all social tasks. In accordance with previous research, older adults performed dual-tasking at a level equivalent to younger adults; they did however show decreased inhibition ability. Dual tasking ability was not found to be related to social performance, some evidence however was found for a role of inhibition as a mediator of decreased social ability with age
