Pica among Persons with Intellectual Disability: Prevalence, Correlates, and Interventions
(University of Waterloo, 2006)<b>Background:</b> Individuals with intellectual disabilities (ID) have a higher prevalence of comorbid psychiatric disorders and challenging behaviours compared to the general population. Though less common, one area ... -
Pick Interpolation and the Distance Formula
(University of Waterloo, 2012-05-09)The classical interpolation theorem for the open complex unit disk, due to Nevanlinna and Pick in the early 20th century, gives an elegant criterion for the solvability of the problem as an eigenvalue problem. In the 1960s, ... -
A Picture is Worth a Thousand Words: A Randomized Controlled Trial to Assess the Impact of a Computerized Pictorial Medication Calendar Medication Taking Behaviour
(University of Waterloo, 2017-08-11)OBJECTIVES The primary was to determine if a pictorial medication calendar would improve patient adherence to supportive medication regimens for adult patients receiving chemotherapy treatment. The secondary objectives ... -
Pictures in an Exhibition
(University of Waterloo, 2013-05-01)Can the female feel at home in nature, myth and on screen, realms where she is so often laid to rest? "Pictures in an Exhibition" is a pastiche that exposes popular culture and art historical tropes in which ambiguous ... -
Picturing Leisure: Using Photovoice to Understand the Experience of Leisure and Dementia
(Nova Southeastern University: College of Arts, Humanities, and Social Sciences, 2013-03-18)Interviews and participant observation are commonly used to explore the experience of dementia, yet may not adequately capture perspectives of persons with dementia as communication changes. We used photovoice (i.e., using ... -
PID Control of Systems with Hysteresis
(University of Waterloo, 2009-04-29)Hysteresis is exhibited by many physical systems. Smart materials such as piezoelectrics, magnetostrictives and shape memory alloys possess useful properties, especially in the field of micropositioning, but the control ... -
The pie sharing problem: Unbiased sampling of N+1 summative weights
(Elsevier, 2022-02)A simple algorithm is provided for randomly sampling a set of N+1 weights such that their sum is constrained to be equal to one, analogous to randomly subdividing a pie into N+1 slices where the probability distribution ... -
Piercing axis-parallel boxes
(The Electronic Journal of Combinatorics, 2018)Let F be a finite family of axis-parallel boxes in Rd such that F contains no k + 1 pairwise disjoint boxes. We prove that if F contains a subfamily M of k pairwise disjoint boxes with the property that for every F E F ... -
Piers, Bridges and Sheds: An architectural response to changing rural geographies and resortscapes (The case of Thornbury, Ontario)
(University of Waterloo, 2011-10-31)Mass tourism is a critical agent of change, with a proven capacity of forging new landscapes and thoroughly modifying the internal structure of a community. Thornbury, a rural settlement located in South-western Ontario, ... -
Pilot Project: Adaptive Strategies for Sustainable Rural Development
(University of Waterloo, 2013-09-20)The outport is in the midst of great change. Twenty years since the moratorium on cod fishing, the province of Newfoundland and Labrador is experiencing rapid economic development in another industrial resource boom. While ... -
A Pilot Study Regarding the Use of Food Waste Grinders in a Multi-Unit Residential Building
(University of Waterloo, 2022-07-25)This study evaluated the impact of food waste grinders (FWGs) in multi-unit residential buildings (MURBs) that also had access to green bins (GBs) on solid waste and wastewater generation. A 15-month technical sampling ... -
Pipe and Ductwork Progress Tracking using 3D Sensing Technologies
(University of Waterloo, 2012-04-30)Automated construction progress tracking is becoming critical to efficient and effective construction management. More and more construction companies are putting aside the old way of tracking progress, which was mainly ... -
Pipeline Flow Behavior of Water-In-Oil Emulsions
(University of Waterloo, 2009-12-23)Water-in-oil (W/O) emulsions consist of water droplets dispersed in continuous oil phase. They are encountered at various stages of oil production. The oil produced from an oil-well usually carries a significant amount of ... -
