What Are the Facilitators and Barriers to Participation in Meaningful Occupations of Retired Community Based Older Adults?
Retirement is an important life transition, with a growing population of individuals in this stage. This thesis explores the meaningfulness of occupations retired individuals engage in and the barriers or facilitators to ... -
EXPECTANCY AS A MEDIATOR OF DRUG AND PLACEBO EFFECTS: METHODOLOGICAL AND CLINICAL CONSIDERATIONS FOR HUMAN RESEARCH OF NICOTINE AND TOBACCO EFFECTS
Drug responses are frequently presumed to arise directly from the pharmacological properties of ingested substances; however, there is growing recognition that non-pharmacological factors likely also make important ... -
IDENTIFICATION AND MANIPULATION OF KEY REGULATORS IN LACE PLANT PROGRAMMED CELL DEATH
The lace plant (Aponogeton madagascariensis) is an aquatic monocot species that has emerged as a model for studying developmental programmed cell death (PCD). In multicellular eukaryotes, PCD plays vital roles in development ... -
A CONDUCTIVITY-BASED MEASUREMENT DEVICE TO DETERMINE VOLUME FRACTION AND GAS SLIP VELOCITY FOR MULTIPHASE FLOW
Multiphase flow metering is needed in the oil and gas industry for well-monitoring, gas fraction, oil cut, and water cut and tracking of solid content. The two-phase flow of gas and liquid is regularly used in the design ... -
The Population Uptake of Laparoscopic Colon Cancer Surgery in Canada:2004-2014
BACKGROUND Although the safety and efficacy of laparoscopic surgery in colon cancer (LAC) have been established, the proportion of colectomies for cancer being performed laparoscopically (use) and uptake (change in use) ... -
STUDIES ON THE ANTI-CANCER PROPERTIES OF ARTESUNATE: ANTI-PROLIFERATIVE AND CYTOTOXIC EFFECTS ON BREAST AND OVARIAN CANCER CELLS
In women, breast cancer is the most prevalent cancer diagnosis while ovarian cancer represents the most lethal gynecological neoplasm. The high incidence and mortality of these cancer types, in addition to the emergence ... -
Abundance of Antibiotic Resistance Genes in Two Municipal Wastewater Treatment Plants and Receiving Water in Atlantic Canada
Antibiotic resistance genes (ARGs) in pathogenic bacteria confer resistance to many clinically important antibiotics and will, if found in treated wastewater and the environment, threaten public health. Using quantitative ... -
The Virtue of Process: Finding the Legitimacy of Judicial Fact-Finding in Personal Injury Litigation
This thesis is an inquiry into the legitimacy of judicial fact-finding in civil litigation. Judges make authoritative factual findings in conditions of uncertainty and the decision-making process cannot, and does not, ... -
MECHANICAL CHARACTERIZATION OF SINGLE MICROBIAL CELLS USING MEMS
In this study, the mechanical properties of single yeast cells (baker’s and brewer’s strains) were measured by an on-chip PolyMUMPs MEMS squeezer in aqueous media. An electrothermal actuator with mechanical amplifiers was ... -
HEMATOLOGICAL PROFILES ASSOCIATED WITH PRODUCTIVE PERFORMANCE AND ESTRUS STATE IN GRASS-FED BEEF HEIFERS
Feeding expenses and reproductive success are major drivers impacting profitability in the cow-calf sector. Similarities between feed efficient phenotypes and estrus state may be supported by markers of energetic shifts. ... -
PHLORIDZIN DOCOSAHEXAENOATE INDUCES CYTOTOXIC EFFECTS IN HUMAN LEUKEMIC CELLS
Polyphenols have potential as pharmacological adjuvants to overcome some clinical challenges that arise in leukemia management. The efficacy of polyphenols can be enhanced by acylation with fatty acids. In this study, the ... -
NOS1APc associates with Hippo Signaling components and contributes to spinal cord development
The nitric oxide synthase 1 adaptor protein (NOS1AP) is an adaptor protein implicated in a number of human conditions including schizophrenia, anxiety and cardiac QT syndrome. Previous studies have shown that NOS1AP and ... -
EFFECT OF MOLECULAR WEIGHT, CHARGE AND HYDROPHOBICITY OF WHEY PEPTIDES ON ENCAPSULATION EFFICIENCY AND SURFACE PROPERTIES OF SOY LECITHIN-DERIVED NANOLIPOSOMES
Encapsulation of peptides has been explored to enhance their stability, but there is a paucity of information on effects of peptide structural properties on encapsulation. Impact of the molecular properties, including ... -
The role of culture in pain-related caregiver behavior: Comparing Canadian, Icelandic, and Thai caregivers of 6-12-year-old children
The aim of the study was to examine the role culture plays in caregiver’s pain-related parent behaviors. This study used a cross-cultural survey design with a convenience sample of caregivers of 6-12-year-old children (N ... -
LABOUR REALLOCATION OUT OF AGRICULTURE. EVIDENCE FROM DEVELOPING COUNTRIES
This dissertation studies the process of reallocation of labour out of agriculture in developing countries. I develop a two-sector general equilibrium model where land is a quasi-fixed factor, and population growth constrains ... -
Field Guide to an Urban Nature: Designing for ecological democracy on McNabs Island
In the middle of the city and on the edge of the ocean, McNabs and Lawlor Islands Provincial Park is an expansive protected area in Halifax, Nova Scotia, Atlantic Canada’s largest metropolitan area. Given its location at ... -
ENHANCING THE EFFECTIVENESS OF SCHOOL-BASED SUBSTANCE USE PREVENTION PROGRAMS: DOES SCHOOL-CONNECTEDNESS PLAY A ROLE?
The aim of this study was to examine whether higher levels of school-connectedness (SC) among high school students are associated with better receptivity of school-based alcohol and drug educational programs, and lower ... -
THE ROLES OF CHEMOKINES, CHEMOKINE RECEPTORS AND GLYCOLIPID ACTIVATION IN NKT CELL TUMOUR INFILTRATION
Higher levels of NKT cell infiltration correlate with improved prognosis in many human cancers. Therefore, we sought to identify factors which contribute to this process. We identified three chemokine receptors, CXCR3, ... -
Development of a novel in vitro model system to characterize the role of activity in motor neurons during development and disease
Neural activity modulates motor axon guidance and synaptic function during development. Differences in neural activity also contribute to the demise of specific motor neuron subtypes in amyotrophic lateral sclerosis (ALS). ... -
Visual Acuity Prediction Based on Transient Sweep Visual Evoked Potentials and the Effect of Image Degradation
Purpose: To investigate the accuracy of a new transient sweep visual evoked potential (SVEP) technology to estimate optotype visual acuity (VA) under various viewing conditions and to compare the standard model for SVEP ...
