The association between access to medical care (physicians and nurse practitioners) and impact on resident outcomes: A retrospective cross-sectional analysis
Creators: Bali, Krittika
Publisher: name: University of Alberta Library
Year: 2022

The nursing home population is vulnerable and medically complex, yet little is known about models of medical service provision and associated quality outcomes. The goal of this thesis project is to examine the association between physician and nurse practitioner accessibility and practice sensitive outcomes. This project used data from the Translating Research in Elder Care (TREC) longitudinal study and the routinely collected Resident Assessment Instrument – Minimum Data Set version 2.0 (RAI-MDS 2.0) to test the association between the availability of physicians (MD) and nurse practitioners (NP) in nursing homes (NH) and clinically-relevant resident outcomes of antipsychotic medication (APM) use without indication of psychosis, physical restraint use,

hospitalization and emergency department (ED) transfers, and polypharmacy. Eight models were created using logistic regression to test the association between the access measures of daily presence of MD or NP on unit and MDs being involved in care planning and each of the four resident outcomes. The sample consisted of 10,888 residents across 320 units in 92 facilities. Staff from 277 (86%) units reported an MD or NP visited daily and 318 (99%) units reported that the MD or NP could be reached when needed. Following adjustment for multiple confounding variables, there were no associations between either measure of access and any of the resident outcomes. For example, the association between having an NP visit the unit on a typical weekday and APM use

(OR= 1.18, 95% CI: 0.56-2.53), NP presence on a unit on a typical weekday and physical restraint use among residents (OR=2.08, 95% CI: 0.26-2.10) and MDs (OR=1.42, 95% CI: 0.54-3.75) should be noted for having wide confidence intervals. Associations between having visits with either an MD or NP at the unit level and hospitalization and ED transfers (OR=1.17, 95% CI: 0.46-3.10) and polypharmacy and visits by either NP or MD (OR=1.37, 95% CI: 0.64-2.93) follow the same trend. There were wide 95% confidence intervals for all estimates of association. Although no associations were identified between these medical care access measures and the selected resident outcomes, the wide confidence intervals demonstrate uncertainty on the point estimates. Additional research with more direct measures of access to medical care is still needed.

A Modest View of the Black Hole Information Paradox

description: Thirty years ago, John Preskill concluded "that the information loss paradox may well presage a revolution in fundamental physics" and mused that "Conceivably, the puzzle of black hole evaporation portends a scientific revolution as sweeping as that that led to the formulation of quantum theory in the early 20th century." Many still agree with this assessment. On the other hand, it seems to me the "paradox" has little to do with the physical world but rather, at best, simply points out the possible inconsistency of two, already disparate, theories (mathematical models) of nature, general relativity and quantum mechanics, with virtually no conceivable observational consequences. The information paradox hinges on the concepts of a pure quantum state, the unitarity of quantum mechanics, and Hawking's semi-classical calculation of black hole evaporation. I used the qualifier "at best" above because, for me, the concept of a quantum state is far more restrictive than required by the paradox while unitarity is not a property of nature but rather of a mathematical model and is already violated by the process of making a measurement. Furthermore, the semi-classical calculation of Hawking is surely of limited applicability.

Characterization of Abrasive Wear by Mass Loss and Acoustic Emission using the Ball-on-Plate Testing
Creators: Kawakami, Haroldo
Publisher: name: University of Alberta Library
Year: 2022

The present work developed an automated ball-on-plate abrasive wear tester and examined the material abrasion wear resistance by volume loss and their acoustic emission characteristics. The performance of three types of materials with varying material properties, including aluminum, polyurethane-coated aluminum and stainless steel, were investigated. Friction and wear testing were carried out under different experimental conditions. To test the effect of normal load, three levels of normal load at approximately 20, 15 and 10 N and three types of lubrication conditions using water, silicone oil and no lubricant were tested. An average sliding velocity of 0.418 m/s and a test duration of 120 s were employed, achieving a total sliding distance of 50.2 m. Two types of acoustic emission data were acquired, including continuous data at 50 Hz and bursts data at 10 MHz. The investigations found that the volume loss due to sliding abrasion for aluminum and stainless steel was inversely proportional to the hardness and proportional to the normal load, which is consistent with the Archard’s equation. Polyurethane, when used as a protective film on aluminum, reduced volume loss due to its high elastic deformability. Overall, stainless steel showed the least volume loss and, thus, the highest abrasion wear resistance, with polyurethane being less and aluminum the least wear resistant. This was likely due to stainless steel having greater hardness than the other two types of materials examined. In addition, AE RMS analysis, FFT transformation and correlation with friction force was performed for 50 Hz continuous data, showing a positive correlation between kinetic friction and delayed onset of AE.  For the 10 MHz burst data, FFT power spectra in dB scale was obtained and compared for different test conditions. Variance, skewness, and kurtosis were calculated on an assumed beta distribution and plotted against time. Furthermore, the Hilbert-Huang transform was applied to the burst data acquired at 40 s, demonstrating patterns in the Hilbert spectra characteristic of material type, normal load and lubrication conditions, and also showing a correlation between volume wear and instantaneous energy. These AE characteristics can potentially be used for abrasion wear monitoring.

Chromatin and epigenetic regulation of Herpes  Simplex Virus 1 lytic genomes
Creators: Hu, MiYao
Publisher: name: University of Alberta Library
Year: 2022

Primary herpes simplex virus 1 (HSV-1) infections are common in childhood,

affecting mainly the oropharyngeal mucosa. The virus is then transported to the

neuronal bodies in the trigeminal ganglia, where it establishes lifelong latency. Although

latent infections are asymptomatic, HSV-1 reactivates upon a variety of stresses,

producing recrudescence of disease and spreading infection. Lytic infections are treated

with several drugs, but latency and reactivation cannot be cured or prevented. HSV-1

chromatin and epigenetic regulation during lytic and latent infections have been studied

for decades. HSV-1 genomes are regularly chromatinized into inaccessible chromatin

during latency but become more accessible during reactivation. Epigenetics thus likely

play a major role in the regulation of HSV-1 transcription, replication, and reactivation

from latency. Although HSV-1 DNA is non-regularly chromatinized in lytic infections,

most current models assume a similar epigenetic regulation for HSV-1 as for cells.

To evaluate the chromatinization of HSV-1 genomes during lytic infections, I

performed nuclease protection assay coupled with bio-physical fractionation, to

separate viral DNA-nucleoprotein complexes by hydrodynamic ratios, followed by deep

sequencing (in collaboration with Dr. Depledge) of each fraction. Gene sampling and

cluster analyses indicated that chromatin dynamics relate to the transcriptional

competency of HSV-1 genomes, not the transcriptional levels of any individual genes or

groups of genes. The transcriptionally competent genomes are in highly dynamic, and

iii

accessible, chromatin and the incompetent ones in far less dynamic, or accessible,

chromatin. Moreover, chromatin insulator elements such as the CCCTC binding factor

(CTCF) flank highly transcribed genome regions from mostly non-transcribed ones. My

findings indicate that chromatin is a key regulator of HSV-1 transcription during lytic

infections in that chromatin provide a first level of regulation, dictating transcriptional

competency. I thus uncovered a new level of viral transcription regulation. During

reactivation, the HSV-1 chromatin also changes from regular, mostly inaccessible,

chromatin to a far more dynamic, and accessible, state. My findings during the lytic

infections thus also provide a framework to better understand HSV-1 latency and

reactivation.
Development  and use of a ray-based analysis tool for the investigation of stimulated Raman scattering in laser-plasma interaction experiments
Creators: Hironaka, Steven
Publisher: name: University of Alberta Library
Year: 2022

Recent long-scale-length spherical target experiments, performed on the OMEGA EP laser, are analyzed for stimulated Raman side-scattering (SRSS). This work has been motivated by results obtained on experiments performed at the Nation Ignition Facility (NIF), relevant to directly-driven inertial confinement fusion (ICF). These NIF experiments have shown SRSS to be an important process, possibly responsible for the observed hot electron generation. Our model, based on ray tracing, is able to explain the time-dependent scattered light spectra from the OMEGA EP experiments: It identifies SRS side-scatter and near backscatter from portions of each incident beam where the scattered electromagnetic wave is generated in the direction parallel to contours of constant density. The nature of SRSS instability (temporal versus spatial growth) is discussed. It is suggested that the OMEGA EP platform could provide a good surrogate in which to develop SRSS mitigation strategies.

description: This study simultaneously examines long-run stock returns and abnormal accruals of
private placements of common stock, convertible debt and straight debt. We investigate
patterns surrounding private placements and compare our results to predictions of
competing hypotheses. We find that the long-term abnormal return for common stock is
significantly positive in the year immediately before the private placement but
significantly negative in the post periods. The abnormal return is significantly negative
for convertible debt in the year immediately following the private placement. Our results
are more consistent with the last-resort financing hypothesis rather than the
overvaluation hypothesis, which is often used to explain the performance of public
issuers.

We show that the Big Crunch singularity is delayed compared to the standard case; the delay crucially depends upon the strength of Galileon correction. As for the phantom Galileon, $ρ_ϕ$ is shown to grow more slowly compared to the standard phantom delaying the approach to singularity. In case, $V\sim ϕ^n, n>4$, Big Rip is also delayed, similar phenomenon is shown to take place for potentials steeper than the exponential.

Building an expert-system based conversational agent to provide personalised resources about neurological disorders
Creators: Sajed, Tanvir
Publisher: name: University of Alberta Library
Year: 2022

Researchers developing artificially intelligent conversational agents (aka, chat-

bots) seek effective ways to provide personal assistance to users with various

needs. We have implemented a web-based conversational agent that recom-

mends resources to help clients (caregivers of patients suffering from various

neurodevelopmental disorders — either family members or health-care pro-

fessionals). Our agent first asks the client a conditional sequence of relevant

questions about the patient’s medical symptoms to fill out a patient profile,

then recommends an appropriate website from a curated knowledge base of

resources, previously validated by experts. We implement this agent as an

expert-system (ES), using an inference engine to make recommendations based

on a knowledge base of information about resources and the information ac-

quired about the patient. This ES technology means the designer can easily

update information about the resources, without redesigning the question-

answering process. We anticipate that our framework can be used in different

applications that require a conversational agent to ask personalised questions

to identify the best recommendations for users.

We show that our proposal covers many models obtained in different schemes of parametrization under one umbrella. We demonstrate that a simple modification in the functional form of Hubble parameter can give rise to interesting cosmological phenomena such as big rip singularity, bounce and others. We have also constrained the model parameters using the latest 28 points of H(z) data for three cases which admit transition from deceleration to acceleration.

A Narrative Inquiry into the Experiences of Two Syrian Refugee Families: Searching for Social Inclusion within Schools
Creators: Vigneau, Gillian Ashley
Publisher: name: University of Alberta Library
Year: 2022

This narrative inquiry explores the experiences of two Syrian refugee families with preschool aged children who arrived in Canada. Narrative inquiry in this study is understood as both methodology and phenomenon under study (Clandinin & Connelly, 2000). The study focus is on their experiences over time as they navigated the complexities of making a home for themselves in Canada. The intent is to understand unique individual stories rather than to focus only on the larger narratives that generalize across families and that may silence individual’s experiences. The study is nested within a larger study (Caine et al., 2017) that explored the experiences of Syrian refugee families as they left Syria and journeyed to Edmonton, Canada. Questions of belonging and social inclusion were central in the overall study and in this study. Within narrative inquiry, a relational methodology, researchers must attend to their own life experiences throughout the study (Clandinin & Connelly, 2000). In order to walk alongside participants, I began the inquiry by telling and inquiring into my stories of experience. I came alongside two families for 18 months and composed field texts including field notes of the places where we met and conversation transcripts of our meetings. I was accompanied in the field by a Syrian interpreter and cultural guide. In a first level of analysis, I composed two narrative accounts (Clandinin, 2013) with attention to the three dimensions of narrative inquiry: temporality, place and sociality (Clandinin & Connelly, 2000). In the second level of analysis, as part of the research team, we looked across all participants’ narrative accounts to discern narrative threads. In this thesis I attend most closely to the bumping places of the families’ experiences with dominant school practices and policies.
An Empirical Study on Learning and Improving the Search Objective for Unsupervised Paraphrasing
Creators: Lu, Weikai S
Publisher: name: University of Alberta Library
Year: 2022

Research in unsupervised text generation has been gaining attention over the years. One recent approach is local search towards a heuristically defined objective, which specifies language fluency, semantic meanings, and other task-specific attributes. Search in the sentence space is realized by word-level edit operations including insertion, replacement, and deletion. However, such objective function is manually designed with multiple components. Although previous work has shown maximizing this objective yields good performance

in terms of true measure of success (i.e. BLEU and iBLEU), the objective landscape is considered to be non-smooth with significant noises, posing challenge for optimization.

In this dissertation, we address the research problem of smoothing the noise in the heuristic search objective by learning to model the search dynamics. Then, the learned model is combined with the original objective function to

guide the search in a bootstrapping fashion. Experimental results show that the learned models combined with the original search objective can indeed provide a smoothing effect, improving the search performance by a small margin.
Neighbourhood income inequality and preschooler’s internalizing and externalizing problems
Creators: Farmer, Gregory
Publisher: name: University of Alberta Library
Year: 2022

Background Several studies have linked neighbourhood social and economic characteristics to preschool-aged children’s emotional and behavioural problems. Although income inequality has been identified as a risk factor for mental health and behavioural outcomes among adolescents, no studies have been conducted on young children less than 10 years of age. The objective of the current study is to explore the association between neighbourhood-level income inequality and internalizing and externalizing problems among preschool-aged children.

Methods We analyzed cross-sectional data from the All Our Families (AOF) longitudinal cohort located in Calgary, Alberta at 3-years postpartum. The analytical sample consisted of 1598 mother-preschooler dyads nested within 184 neighbourhoods. Mothers completed the National Longitudinal Survey of Children and Youth adapted Child Behaviour Checklist (NLSCY- CBCL), which assessed internalizing and externalizing symptoms of their child. Multilevel logistic regression modelling was used to assess a relationship between neighbourhood income inequality measured via the Gini coefficient and preschooler’s internalizing and externalizing problems.

Results The mean Gini coefficient across the 184 neighbourhoods was 0.33 (S.D = 0.05) and ranged from 0.23 to 0.55. Neighbourhood income inequality was not associated with either externalizing (OR = 1.04, 95%CI: 0.89, 1.20) or internalizing (OR = 0.96, 95%CI: 0.84, 1.14) problems in preschoolers. Before-tax household income was significant in internalizing (OR = 1.38, 95%CI: 1.02,1.86), however, was not significant for externalizing problems in fully adjusted models.

Conclusion Neighbourhood-level inequality is not associated with internalizing or externalizing problems at 3-years of age. No association was observed among preschool-aged children because they may be too young to experience its effects or are more sensitive to the household environment such as lower household incomes, as opposed to their neighbourhood environment.

description: We present a new algorithm which detects the maximal possible number of matched disjoint pairs satisfying a given caliper when a bipartite matching is done with respect to a scalar index (e.g., propensity score), and constructs a corresponding matching. Variable width calipers are compatible with the technique, provided that the width of the caliper is a Lipschitz function of the index. If the observations are ordered with respect to the index then the matching needs $O(N)$ operations, where $N$ is the total number of subjects to be matched. The case of 1-to-$n$ matching is also considered. We offer also a new fast algorithm for optimal complete one-to-one matching on a scalar index when the treatment and control groups are of the same size. This allows us to improve greedy nearest neighbor matching on a scalar index. Keywords: propensity score matching, nearest neighbor matching, matching with caliper, variable width caliper.

Molecular pathotyping platforms for the clubroot pathogen, Plasmodiophora brassicae
Creators: Tso, Heather H
Publisher: name: University of Alberta Library
Year: 2022

Clubroot, caused by the soilborne pathogen Plasmodiophora brassicae, is a threat to cruciferous crops worldwide and an important disease of canola (Brassica napus L.) in Canada. At present, pathotypes of P. brassicae are distinguished phenotypically based on their virulence patterns on host differential sets, including the systems of Williams, Somé et al., the European Clubroot Differential set, and most recently, the Canadian Clubroot Differential and the Sinitic Clubroot Differential sets. While these are frequently used because of their simplicity of application, they are time-consuming, labor-intensive, and can lack sensitivity. Early and preventative pathotype detection is imperative to maximize productivity and promote sustainable crop production. The decreased turnaround time and increased specificity of molecular pathotyping will be valuable for the development of integrated clubroot management strategies, and interest in molecular approaches to complement phenotypic bioassays is increasing. In this study, two rapid and sensitive molecular P. brassicae pathotyping assays were developed, the first using RNase H2-dependent PCR (rhPCR) technology, and the second using a modified single base extension technique known as SNaPshot. Both assays clearly distinguished between pathotype clusters. The results correlated fully with whole genome sequencing data in silico for all 38 single-spore isolates of P. brassicae tested. Additional isolates from pathotyped clubroot galls and from samples in a single-blind test were also identified correctly. The rhPCR assay generated differentiating electrophoretic bands without non-specific amplification. The SNaPshot assay was able to detect down to a 10% relative allelic proportion in template (pathotype) mixtures with both single-spore and field isolates. Collectively, the results demonstrated that the rhPCR-based and single base extension assays developed in this study may be used as fast and reliable diagnostic tools to detect and distinguish between P. brassicae pathotype clusters. The ability to identify pathotypes in a rapid manner will aid in clubroot diagnosis and surveillance activities, complementing traditional bioassays.

title: Entwicklung eines Leitfades zur Abschätzung der Wirtschaftlichkeit des Einsatzes einer Kleinstwasserkraftanlage in einem Entwicklungsland
Creators: name: Priester, Marvin

description: Kleinstwasserkraft stellt eine valide Option zur Elektrifizierung ruraler Gebiete in Schwellen- und Entwicklungsländern mit erneuerbarer Energie da. Kleinstwasserkraftanlagen haben den Vorteil, bereits bei sehr geringen Fallhöhen und Durchflüssen arbeiten zu können, ökologisch verträglich zu sein und eine hohe soziale Akzeptanz aufzuweisen. Ein Nachteil liegt jedoch in den hohen Kapitalkosten der Anlagen, die von den meisten Kommunen in Entwicklungsländern nicht alleine getragen werden können und die deshalb auf die Hilfe eines Investors angewiesen sind. Investoren besitzen jedoch meist nicht die nötige technische Expertise, um die Eignung einer Kleinstwasserkraftanlage an einem gegeben Standort abschätzen zu können. Diese Arbeit stellt einen Leitfaden für die Abschätzung der Wirtschaftlichkeit einer Kleinstwasserkraftanlage in einem Entwicklungsland dar. Es existiert eine Vielzahl von Turbinen für die Kleinstwasserkraft und sie stellen den Kern jeder Anlage dar. Es wird ein Überblick über gängige Kleinstwasserkraftturbinen gegeben. Zusätzlich werden bestehende Kleinstwasserkraftsysteme beschrieben. Die wesentlichen Einflussparameter (hydrologisch, technisch, wirtschaftlich…), welche für den erfolgreichen Einsatz einer Kleinstwasserkraftanlage notwendig sind, werden aufgelistet und erläutert. Anschließen sorgt eine Checkliste dafür, dass ein Investor die Wirtschaftlichkeit einer Anlage an einem gegeben Standort grob abschätzen kann.

description: The uncertainty of multidimensional shift spaces draws attracted attention of researchers. For example, the emptiness problem is undecidable; there exist aperiodic shifts of finite type; there is a nonempty shift of finite type exhibiting nonextensible local patterns. This paper investigates symbolic dynamics on Cayley trees and gives affirmative answers to the above questions in tree-shifts. Beyond that, with introducing block gluing tree-shift, a sufficient condition of exhibiting positive topological entropy is revealed.

description: The notion of tree-shifts constitutes an intermediate class in between one-sided shift spaces and multidimensional ones. This paper proposes an algorithm for computing of the entropy of a tree-shift of finite type. Meanwhile, the entropy of a tree-shift of finite type is $\dfrac{1}{p} \ln λ$ for some $p \in \mathbb{N}$, where $λ$ is a Perron number. This extends Lind's work on one-dimensional shifts of finite type. As an application, the entropy minimality problem is investigated, and we obtain the necessary and sufficient condition for a tree-shift of finite type being entropy minimal with some additional conditions.

description: This paper has examined the uses of fungi and associated mycorhizae in crop production. Integrated controls such as chemical and biological methods of pest reduction for the general fungi and enhancement of nutrition for the mycorhizae were considered. Actions of two general types of mycorhizae (endotropic and ectotropic) were also investigated based on their structure. Fungi that are capable of entering into the mycorhizal relationship were found to be of several groups, viz: Phycomycetess, Ascomycetes, Basidiomycetec and fungi imperfecti. The paper concludes that both fungi and mycorhizae can enhance the yield of crops in a perfect symbiotic relationship.

description: In classical physics, properties of the objects exist independently on the context, i.e. whether and how measurements are performed. Quantum physics showed this assumption to be wrong and that Nature is indeed "contextual". Contextuality has been observed in the simplest physical systems such as single particles, and plays fundamental roles in quantum computation advantage. Here, we demonstrate for the first time quantum contextuality in an integrated photonic chip. The chip implements different combinations of measurements on a single photon delocalized on four distinct spatial modes. We show violations of a CHSH-like non-contextuality inequality by 14 standard deviations. This paves the way to compact and portable devices for contextuality-based quantum-powered protocols.

Characterization and Treatment of Chromatin Remodeling Protein Deficient DDEC

Some of the most aggressive endometrial cancer cases display extensive heterogeneity within the same tumor in the form of mixed undifferentiated and well-differentiated phenotypes.  The emergence of dedifferentiation in higher grade endometrial carcinomas presents an obstacle for both timely and accurate diagnosis and specific and effective treatment.  Even though endometrial cancers of this nature are less common, we used a collection of patient tissue and developed cell line-based models of disease using gene editing technology to discover and interrogate many features of dedifferentiated endometrial cancer or DDEC.  Firstly, utilizing targeted sequencing and gene expression profiling paired with immunohistochemistry, I discovered loss of chromatin remodellers and markers of epithelial differentiation to be a defining feature of the undifferentiated portions of DDEC neoplasms. By comparing the profiles of the undifferentiated regions to their well-differentiated predecessors within the same tumor, I also demonstrated the emergence of a population of undifferentiated cells within DDEC acquires cancer stem cell-like features.  Secondly, three models of DDEC with absent SWI/SNF chromatin remodelling complex subunit SMARCA4 expression, were generated and extensively characterized.  I thoroughly documented how in vitro, SMARCA4 loss results in endometrial cancer cells exhibiting senescence but in vivo, SMARCA4 deficiency leads to the formation of tumors that recapitulate clinical DDEC neoplasms.  I propose dysregulation of transcription factors governing epithelial cell-related gene expression as a major driver of dedifferentiation in the context of DDEC.  Finally, screening of one of the isogenic pairs of gene edited endometrial cancer cells, revealed several synthetic lethal vulnerabilities specific to cells with absent SMARCA4 expression. In vitro, I extensively validated many of the hits and found chemical inhibition of CDK4 and EGFR both alone and in combination to be potentially effective in targeting DDEC-like cells. Preclinical animal studies demonstrated the efficacy of targeting CDK4 and EGFR may be counteracted by in vivo transformation of the model and stromal contribution.  In its totality, the work in this thesis provides one of the first comprehensive examinations of DDEC and my development of and findings with the cell line models of this malignancy constitute a noteworthy contribution to our overall understanding of SWI/SNF deficient cancers of the gynecological tract.
Lyapunov exponents for the random product of two shears

description: We give lower and upper bounds on both the Lyapunov exponent and generalised Lyapunov exponents for the random product of positive and negative shear matrices. These types of random products arise in applications such as fluid stirring devices. The bounds, obtained by considering invariant cones in tangent space, give excellent accuracy compared to standard and general bounds, and are increasingly accurate with increasing shear. Bounds on generalised exponents are useful for testing numerical methods, since these exponents are difficult to compute in practice.

description: A spatially homogeneous anisotropic LRS Bianchi type-I cosmological model is studied in $f(R,T)$ gravity with a special form of Hubble's parameter, which leads to constant deceleration parameter. The parameters involved in the considered form of Hubble parameter can be tuned to match, our models with the $Λ$CDM model. With the present observed value of the deceleration parameter, we have discussed physical and kinematical properties of a specific model. Moreover, we have discussed the cosmological distances for our model.

description: We construct a factorization of the Giry monad through the category of convex spaces, and show that, provided that no measurable cardinals exist, probability measures can be viewed as natural transformations. Using the adjunction of this factorization, we then show the category of Giry algebras is equivalent to the category of convex measurable spaces where the $σ$-algebra structure associated with a convex space satisfies an elementary property.
description: Lemma 9.5 page 13 is incorrect. The Giry monad cannot be factored through the category of convex spaces except for finite spaces. Using standard measurable spaces one can obtain an adjoint factorizaton, and is described in the article Giry algebras for standard measurable spaces (2022)
Oncology Patients’ Experiences of Using Electronic Patient Portals and Other Online Tools to Support Care and Treatment

With the current proliferation of clinical information technologies in Canada, patient portals and other online tools are becoming increasingly adopted in healthcare. Many people use the Internet for health-related purposes to connect with peer support groups and read about their medical conditions and prescribed medications. Research studies show that oncology patients have a keen interest in portals, as they often require more comprehensive health information when compared to the general population. In Canada, patient portal technology is relatively new and evidence on the benefits of portals is limited. Moreover, research has not been conducted in Canada regarding the use and effects of patient portals in oncology practice. This qualitative descriptive study employed individual semi-structured interviews with oncology patients and/or their family caregivers to explore patient experiences of using portals and other online tools for care and treatment. Eleven participants were enrolled in the study. Interviews were audio-recorded and transcribed verbatim. Using thematic analysis, the following themes were identified: (i) experiencing doubt and the desire for transparency; (ii) becoming an informed and active member of the healthcare team; (iii) encountering complexity; and (iv) emphasizing the importance of the patient-provider relationship. Although participants considered online tools as beneficial, it was unclear whether they actually fostered feelings of empowerment; thus, further research is needed to clarify this association
