description: This study aims to investigate the current status of studies on "neophobia and gastronomic tourism" published in the international literature over the last 41 years (1980-2021). The data was extracted from Web of Science (WOS), and so a bibliometric analysis of the publications indexed in WOS was made in this study. The Vosviewer program was employed in order to analyse and visualize the data for a total of 3269 studies on the subject of "neophobia and gastronomy tourism" from the relevant database. Besides, the analysis of the data was supported by the R package program. It has been observed that there are 2113 articles out of 3269 documents on neophobia and gastronomy tourism and that the highest number of articles were published in 2021. The findings indicate that the most cited author was Siegrist, M. and that the most cited document was Birch, I.I. (1999). Also, it has been found that the most co-cited article was written by Pliner, P. The United States, with the most cited and strongest ties, also appears to be the most prolific country. This study is presenting an overview of neophobia and gastronomy tourism research which has been conducted over the last 41 years through bibliometric analysis.

description: We describe a versatile toolbox for the quantum simulation of many-body lattice models, capable of exploring the combined effects of background Abelian and non-Abelian gauge fields, bond and site disorder, and strong on-site interactions. We show how to control the quantum dynamics of particles trapped in lattice potentials by the photon-assisted tunneling induced by periodic drivings. This scheme is general enough to be applied to either bosons or fermions with the additional advantage of being non-perturbative. It finds an ideal application in microfabricated ion trap arrays, where the quantized vibrational modes of the ions can be described by a quantum lattice model. We present a detailed theoretical proposal for a quantum simulator in that experimental setup, and show that it is possible to explore phases of matter that range from the fractional quantum Hall effect, to exotic strongly-correlated glasses, or flux-lattice models decorated with arbitrary patterns of localized defects.

description: Growing concerns surrounding children’s changing socioenvironmental contexts, such as the increasing impacts of urbanization and decreases in unstructured outdoor play, have led to the emergence of an intentional movement to increase natural play spaces. Among the variety of natural play space initiatives are natural playgrounds: play spaces that encompass a wide variety of interpretations, but generally involve the intentional incorporation of natural features and materials into the playground. Research on natural playgrounds has increased; however, several areas of inquiry remain, including a need for increased understanding of children’s perspectives on natural playground sites and more critical considerations of the complexities surrounding these spaces. In this qualitative study, I explore several areas of inquiry in relation to natural playgrounds in Calgary, Alberta. These areas of inquiry include play affordances, issues of accessibility and inclusivity, concepts of nature and sustainability, and settler colonialism in relation to natural playground development and usage in Calgary, Alberta. This study focuses on the development and usage of five natural playground sites. Primary research methods include online and mobile/walking interviews with 44 natural playgrounds users (e.g., children and caregivers) and seven playground developers (e.g., designers). This study is theoretically informed by political ecology, concepts of nature, and play affordances. Findings from this study are presented in a manuscript-based dissertation, which comprises four manuscripts along with two introductory chapters and a conclusion.

description: This work introduces a new concept, the so-called Darboux family, which is employed to determine, to analyse geometrically, and to classify up to Lie algebra automorphisms, in a relatively easy manner, coboundary Liebialgebras on real four-dimensional indecomposable Lie algebras. The Darboux family notion can be consideredas a generalisation of the Darboux polynomial for a vector field. The classification of $r$-matrices and solutions to classical Yang-Baxter equations for real four-dimensional indecomposable Lie algebras is also given in detail. Our methods can further be applied to general, even higher-dimensional, Lie algebras. As a byproduct, a method to obtain matrix representations of certain Lie algebras with a non-trivial center is developed.

description: Recently, a number of physical models has emerged described by a random process with increments given by a quadratic form of a fast Gaussian process. We find that the rate function which describes sample-path large deviations for such a process can be computed from the large domain size asymptotic of a certain Fredholm determinant. The latter can be evaluated analytically using a theorem of Widom which generalizes the celebrated Szegő-Kac formula to the multi-dimensional case. This provides a large class of random dynamical systems with time scale separation for which an explicit sample-path large deviation functional can be found. Inspired by problems in hydrodynamics and atmosphere dynamics, we construct a simple example with a single slow degree of freedom driven by the square of a fast multi-variate Gaussian process and analyse its large deviations functional using our general results. Even though the noiseless limit of this example has a single fixed point, the corresponding large deviations effective potential has multiple fixed points. In other words, it is the addition of noise that leads to metastability. We use the explicit answers for the rate function to construct instanton trajectories connecting the metastable states.

description: Space-borne missions CoRoT and {\it Kepler} are providing a rich harvest of high-quality constraints on solar-like pulsators. Among the seismic parameters, mode damping rates remains poorly understood and thus barely used to infer physical properties of stars. Nevertheless, thanks to CoRoT and {\it Kepler} space-crafts it is now possible to measure damping rates for hundreds of main-sequence and thousands of red-giant stars with an unprecedented precision. By using a non-adiabatic pulsation code including a time-dependent convection treatment, we compute damping rates for stellar models representative for solar-like pulsators from the main-sequence to the red-giant phase. This allows us to reproduce the observations of both CoRoT and {\it Kepler}, which validates our modeling of mode damping rates and thus the underlying physical mechanisms included in the modeling. Actually, by considering the perturbations of turbulent pressure and entropy (including perturbation of the dissipation rate of turbulent energy into heat) by the oscillation in our computation, we succeed in reproducing the observed relation between damping rates and effective temperature. Moreover, we discuss the physical reasons for mode damping rates to scale with effective temperature, as observationally exhibited. Finally, this opens the way for the use of mode damping rates to probe turbulent convection in solar-like stars.

description: Geophysical inversion involves determining the subsurface properties of the earth by analyzing geophysical data. Conventionally, geophysical inversions have encountered several challenges including non-unique solutions, nonlinearity, low-resolution and noisy data analyses, mandatory constraints and simplifications, computational costs, and subjective interpretations. Addressing these challenges necessitates the development of advanced inversion algorithms to enable a more comprehensive and robust analysis of subsurface properties. Implementing deep neural networks, this thesis conducts nonlinear inversions of gravity and magnetic data for subsurface modeling by learning complex patterns and relationships in large training datasets. Nevertheless, a key challenge lies in the scarcity of large-scale training datasets required for the intelligent inversion problem. To address this issue, a novel technique has been developed to simulate geopotential datasets that represent the characteristics of real-world subsurface properties and their corresponding geopotential data. The technique's adaptability to diverse subsurface complexities allows for more comprehensive and accurate nonlinear inversion of geopotential data. The dataset simulation technique adopts forward modeling to visualize the subsurface into crustal layers and incorporates physic-based constraints into the process. To ensure comprehensive coverage of geological complexities in the forward models, the technique incorporates multiple structural parameters. This results in randomized changes in the topography and depth of the subsurface layers. The forward model simulations are followed by calculating their synthetic gravity and magnetic anomalies. The final training dataset is created by putting together the calculated gravity and magnetic anomalies of the forward models as input features and the topography of the subsurface layers as labels. The application of the proposed technique is practiced on airborne gravity and aeromagnetic anomalies offshore Abu Dhabi, United Arab Emirates. Using simulated datasets, several deep neural network models are trained to implement inversion of gravity anomalies, inversion of magnetic anomalies, and joint inversion of gravity and magnetic anomalies. The performance of the models is evaluated on actual and noise-added synthetic gravity and magnetic anomalies. By leveraging the trained models, the salts and basement structures are investigated, providing valuable insights into the geological structures of hydrocarbon reservoirs in this region.

description: We numerically investigate the electric potential distribution over a two-dimensional continuum percolation model between the electrodes. The model consists of overlapped conductive particles on the background with an infinitesimal conductivity. Using the finite difference method, we solve the generalized Laplace equation and show that in the potential distribution, there appear the {\it{quasi-equipotential clusters}} which approximately and locally have the same values like steps and stairs. Since the quasi-equipotential clusters has the fractal structure, we compute the fractal dimension of equipotential curves and its dependence on the volume fraction over $[0,1]$. The fractal dimension in [1.00, 1.257] has a peak at the percolation threshold $p_c$.

description: Computationally intractable tasks are often encountered in physics and optimization. Such tasks often comprise a cost function to be optimized over a so-called feasible set, which is specified by a set of constraints. This may yield, in general, to difficult and non-convex optimization tasks. A number of standard methods are used to tackle such problems: variational approaches focus on parameterizing a subclass of solutions within the feasible set; in contrast, relaxation techniques have been proposed to approximate it from outside, thus complementing the variational approach by providing ultimate bounds to the global optimal solution. In this work, we propose a novel approach combining the power of relaxation techniques with deep reinforcement learning in order to find the best possible bounds within a limited computational budget. We illustrate the viability of the method in the context of finding the ground state energy of many-body quantum systems, a paradigmatic problem in quantum physics. We benchmark our approach against other classical optimization algorithms such as breadth-first search or Monte-Carlo, and we characterize the effect of transfer learning. We find the latter may be indicative of phase transitions, with a completely autonomous approach. Finally, we provide tools to generalize the approach to other common applications in the field of quantum information processing.

description: We present a consistent \emph{ab initio} computation of the longitudinal response function $R_L$ in $^{40}$Ca using the coupled-cluster and Lorentz integral transform methods starting from chiral nucleon-nucleon and three-nucleon interactions. We validate our approach by comparing our results for $R_L$ in $^4$He and the Coulomb sum rule in $^{40}$Ca against experimental data and other calculations. For $R_L$ in $^{40}$Ca we obtain a very good agreement with experiment in the quasi-elastic peak up to intermediate momentum transfers, and we find that final state interactions are essential for an accurate description of the data. This work presents a milestone towards \emph{ab initio} computations of neutrino-nucleus cross sections relevant for experimental long-baseline neutrino programs.

description: We establish long-time existence for a projected Sobolev gradient flow of generalized integral Menger curvature in the Hilbert case, and provide $C^{1,1}$-bounds in time for the solution that only depend on the initial curve. The self-avoidance property of integral Menger curvature guarantees that the knot class of the initial curve is preserved under the flow, and the projection ensures that each curve along the flow is parametrized with the same speed as the initial configuration. Finally, we describe how to simulate this flow numerically with substantially higher efficiency than in the corresponding numerical $L^2$ gradient descent or other optimization methods.

description: We propose an interesting BPS/CFT correspondence playground: the correlation function of two intersecting half-BPS surface defects in four-dimensional $\mathcal{N}=2$ supersymmetric $SU(N)$ gauge theory with $2N$ fundamental hypermultiplets. We show it satisfies a difference equation, the fractional quantum T-Q relation. Its Fourier transform is the $5$-point conformal block of the $\widehat{\mathfrak{sl}}_N$ current algebra with one of the vertex operators corresponding to the $N$-dimensional $\mathfrak{sl}_N$ representation, which we demonstrate with the help of the Knizhnik-Zamolodchikov equation. We also identify the correlator with a state of the $XXX_{\mathfrak{sl}_2}$ spin chain of $N$ Heisenberg-Weyl modules over $Y(\mathfrak{sl}_2)$. We discuss the associated quantum Lax operators, and connections to isomonodromic deformations.

description: Liquified noble gases are widely used as a target in direct Dark Matter searches. Signals from scintillation in the liquid, following energy deposition from the recoil nuclei scattered by Dark Matter particles (e.g. WIMPs), should be recorded down to very low energies by photosensors suitably designed to operate at cryogenic temperatures. Liquid Argon based detectors for Dark Matter searches currently implement photo multiplier tubes for signal read-out. In the last few years PMTs with photocathodes operating down to liquid Argon temperatures (87 K) have been specially developed with increasing Quantum Efficiency characteristics. The most recent of these, Hamamatsu Photonics Mod. R11065 with peak QE up to about 35%, has been extensively tested within the R&D program of the WArP Collaboration. During these testes the Hamamatsu PMTs showed superb performance and allowed obtaining a light yield around 7 phel/keVee in a Liquid Argon detector with a photocathodic coverage in the 12% range, sufficient for detection of events down to few keVee of energy deposition. This shows that this new type of PMT is suited for experimental applications, in particular for new direct Dark Matter searches with LAr-based experiments.

description: The state function entropy and its quantum thermodynamical implication for two typical dissipative systems with anomalous spectral densities are studied by investigating on their low-temperature quantum behavior. In all cases it is found that the entropy decays quickly and vanishes as the temperature approaches zero. This reveals a good conformity with the third law of thermodynamics and provides another evidence for the validity of fundamental thermodynamical laws in the quantum dissipative region.

description: We apply a parametric reconstruction method to a homogeneous, isotropic and spatially flat Friedmann-Robertson-Walker (FRW) cosmological model filled of a fluid of dark energy (DE) with constant equation of state (EOS) parameter interacting with dark matter (DM). The reconstruction method is based on expansions of the general interaction term and the relevant cosmological variables in terms of Chebyshev polynomials which form a complete set orthonormal functions. This interaction term describes an exchange of energy flow between the DE and DM within dark sector. To show how the method works we do the reconstruction of the interaction function expanding it in terms of only the first six Chebyshev polynomials and obtain the best estimation for the coefficients of the expansion assuming three models: (a) a DE equation of the state parameter $w =-1$ (an interacting cosmological $Λ$), (b) a DE equation of the state parameter $w =$ constant with a dark matter density parameter fixed, (c) a DE equation of the state parameter $w =$ constant with a free constant dark matter density parameter to be estimated, and using the Union2 SNe Ia data set from "The Supernova Cosmology Project" (SCP) composed by 557 type Ia supernovae. In both cases, the preliminary reconstruction shows that in the best scenario there exist the possibility of a crossing of the noninteracting line Q=0 in the recent past within the $1σ$ and $2σ$ errors from positive values at early times to negative values at late times. This means that, in this reconstruction, there is an energy transfer from DE to DM at early times and an energy transfer from DM to DE at late times. We conclude that this fact is an indication of the possible existence of a crossing behavior in a general interaction coupling between dark components.

Incorporating delayed entry into the joint frailty model for recurrent events and a terminal event

description: In studies of recurrent events, joint modeling approaches are often needed to allow for potential dependent censoring by a terminal event such as death. Joint frailty models for recurrent events and death with an additional dependence parameter have been studied for cases in which individuals are observed from the start of the event processes. However, the samples are often selected at a later time, which results in delayed entry. Thus, only individuals who have not yet experienced the terminal event will be included in the study. We propose a method for estimating the joint frailty model from such left-truncated data. The frailty distribution among the selected survivors differs from the frailty distribution in the underlying population if the recurrence process and the terminal event are associated. The correctly adjusted marginal likelihood can be expressed as a ratio of two integrals over the frailty distribution, which may be approximated using Gaussian quadrature. The baseline rates are specified as piecewise constant functions, and the covariates are assumed to have multiplicative effects on the event rates. We assess the performance of the estimation procedure in a simulation study, and apply the method to estimate age-specific rates of recurrent urinary tract infections and mortality in an older population.

Publisher: name: Journal of Tourism & Development
Year: 2023

description: This article presents the interplay of community-based tourism (CBT), local supply and carrying capacity by focusing on how to decrease leakages related to goods and services in tourism (such a food and drink, construction material for accommodation establishments and tourism services). It is a conceptual paper whose aim is to present a new direction in tourism carrying capacity to enhance local impacts. It advances a different approach to carrying capacity linked to the concept of CBT, where a company’s Corporate Social Responsibility also contributes to the local economy in pursuit of tourism linkages. A new approach to carrying capacity is suggested steeped in local resources, both human and natural, supply capacity and the concept of CBT. The article argues that communities must define their own development trajectories based on their capabilities, capacities and context.

description: We study the impact of the assumed velocity distribution of galactic dark matter particles on the interpretation of results from nuclear recoil detectors. By converting experimental data to variables that make the astrophysical unknowns explicit, different experiments can be compared without implicit assumptions concerning the dark matter halo. We extend this framework to include the annual modulation signal, as well as multiple target elements. Recent results from DAMA, CoGeNT and CRESST-II can be brought into agreement if the velocity distribution is very anisotropic and thus allows a large modulation fraction. However constraints from CDMS and XENON cannot be evaded by appealing to such astrophysical uncertainties alone.

Multi-Agent Modelling of Industrial Cyber-Physical Systems for IEC 61499 Based Distributed Intelligent Automation

description: Traditional industrial automation systems developed under IEC 61131-3 in centralized architectures are statically programmed with determined procedures to perform predefined tasks in structured environments. Major challenges are that these systems designed under traditional engineering techniques and running on legacy automation platforms are unable to automatically discover alternative solutions, flexibly coordinate reconfigurable modules, and actively deploy corresponding functions, to quickly respond to frequent changes and intelligently adapt to evolving requirements in dynamic environments. The core objective of this research is to explore the design of multi-layer automation architectures to enable real-time adaptation at the device level and run-time intelligence throughout the whole system under a well-integrated modelling framework. Central to this goal is the research on the integration of multi-agent modelling and IEC 61499 function block modelling to form a new automation infrastructure for industrial cyber-physical systems. Multi-agent modelling uses autonomous and cooperative agents to achieve run-time intelligence in system design and module reconfiguration. IEC 61499 function block modelling applies object-oriented and event-driven function blocks to realize real-time adaption of automation logic and control algorithms. In this thesis, the design focuses on a two-layer self-manageable architecture modelling: a) the high-level cyber module designed as multi-agent computing model consisting of Monitoring Agent, Analysis Agent, Self-Learning Agent, Planning Agent, Execution Agent, and Knowledge Agent; and b) the low-level physical module designed as agent-embedded IEC 61499 function block model with Self-Manageable Service Execution Agent, Self-Configuration Agent, Self-Healing Agent, Self-Optimization Agent, and Self-Protection Agent. The design results in a new computing module for high-level multi-agent based automation architectures and a new design pattern for low-level function block modelled control solutions. The architecture modelling framework is demonstrated through various tests on the multi-agent simulation model developed in the agent modelling environment NetLogo and the experimental testbed designed on the Jetson Nano and Raspberry Pi platforms. The performance evaluation of regular execution time and adaptation time in two typical conditions for systems designed under three different architectures are also analyzed. The results demonstrate the ability of the proposed architecture to respond to major challenges in Industry 4.0.
Intensive care unit patients in the post-anesthetic recovery room : a case study exploring how registered nurses manage change
Creators: name: White, Crystal Andria
Publisher: name: University of British Columbia

description: Health care in the acute setting is in a constant state of change with evolving technology, higher acuity, and changing patient care models. In the midsize hospital in this study there was a practice change which involved the Recovery Room nurses caring for Intensive Care Unit (ICU) overflow patients. The purpose of this research was to explore the experiences of the Recovery Room nurses during this practice change. Six Recovery Room nurses from this midsized hospital participated in this study. Participants were interviewed using a semi-structured format with open-ended questions to guide the conversation. Interviews lasted 25 to 35 minutes, were digitally recorded, transcribed verbatim by a transcriptionist, and then checked for accuracy. Interpretive Description was used to guide the data analysis. The first three transcripts were read independently by co-investigators who then met to construct an initial coding framework. This framework was used to code the remaining interviews with constant comparative analysis to ensure accuracy and integrity of the codes. The coding framework was then reviewed by the remaining committee members to further enhance coding integrity. The coding framework was continually refined throughout the study to strive for accuracy. Three main themes were constructed from the data: the Expert Mind-set, Specialty Practice and Unit Culture. Expert mind-set was further broken down into sub-themes, Knowing but not Doing and Dual Focus/Dual Duty. Specialty Practice was broken down into sub-themes Doing but not Knowing and Contextual Supports. Finally, Unit Culture was broken down into Identity and Relationships. These findings lead to a more in-depth discussion of the dilemma of not being able to deliver a standard of care, i.e. the concept of knowing but not doing, and the dilemma of generalist versus specialist approach to critical care, i.e. the concept of doing but not knowing. The results of this study have multifaceted implications which include the use of a change model when implementing practice change; developing relationships to support practice change; valuing a self-directed learning culture; and the importance of having practice standards and resources available to support practice change.

description: An object's interior material properties, while invisible to the human eye, determine motion observed on its surface. We propose an approach that estimates heterogeneous material properties of an object from a monocular video of its surface vibrations. Specifically, we show how to estimate Young's modulus and density throughout a 3D object with known geometry. Knowledge of how these values change across the object is useful for simulating its motion and characterizing any defects. Traditional non-destructive testing approaches, which often require expensive instruments, generally estimate only homogenized material properties or simply identify the presence of defects. In contrast, our approach leverages monocular video to (1) identify image-space modes from an object's sub-pixel motion, and (2) directly infer spatially-varying Young's modulus and density values from the observed modes. We demonstrate our approach on both simulated and real videos.

description: With tourists’ growing interest in revitalising their bodies, mind, and spirit through learning and practicing yoga, yoga tourism is getting attention rapidly in academia and industry, The age-long practice of yoga, ayurveda, and meditation make India an excellent hotspot for yoga tourism. Patanjali Yogpeeth is chosen as the area of the study, considering its prominence and impact on the whole industry. The institution promotes exercise, research, and advances in ayurveda and yoga. This research examines the influence of electronic word of mouth (E-WoM) and servicescape on tourists’ revisit intention to the Patanjali Yogpeeth with the mediating role of tourist satisfaction. Quantitative methodology was applied in the current study, and 231 tourists’ data was collected from those who have revisited Patanjali Yogpeeth. The findings showed that tourists’ revisit intention towards Patanjali Yogpeeth has a significant relationship with E-WoM and servicescape. In addition, perceived satisfaction mediates the relationship between tourists’ revisit intention and E-WoM and servicescape. From the practical aspect, this research will help the tourism and travel industry stakeholders with empirical evidence. From the theoretical aspect, the study extends the applicability of the Stimulus Organism Response (S-O-R) theory.

description: This paper aims to understand the perceptions of tourism-related business owners/managers regarding the use of digital technologies for the provision, dynamization, and communication of cultural experiences targeting families. To achieve this aim, a qualitative approach was adopted by conducting ten semi-structured interviews with business owners/managers operating in the District of Viana do Castelo, in Northwest Portugal. Participants were selected through a convenience sampling method after being initially identified as licensed by Turismo de Portugal at the National Register of Tourism leisure-related Agents, offering cultural experiences and online presence. The interviews were transcribed and analysed manually, based on a systematic analysis matrix. The research shows that digital technologies are not used very often by companies and that the ones they use are mostly related to promotional activities (Social Media and Websites). Nevertheless, disadvantages and barriers to its use are also acknowledged. Finally, practical and theoretical implications are highlighted, along with suggestions for further future research.

description: Being the birthplace of Sikhism, Pakistan has massive tourism potential related to Sikh Pilgrimage. However, it has failed to make this sector a boosting industry. The study aims to find the impediments of this sector and the problems faced by Sikh pilgrims during their pilgrimage journey (Yatra) in Pakistan. The study used a qualitative approach. The data was collected through questionnaires, visits, and interviews with pilgrims and govt. Officials. The findings showed that the Pilgrimage sector faced many problems, including Indo-Pak bilateral tension and strict visa policy, lack of advertisement campaigns, poor law and order situation, infrastructural & transportation issues, etc. Therefore, to make the Sikh tourism sector a multi-million-dollar industry these issues must be addressed.

description: Context. The properties of variable stars can give independent constraints on the star formation history of the host galaxy, by determining the age and metallicity of the parent population. Aims. We investigate the pulsation properties of 84 Anomalous Cepheids (ACs) detected by the OGLE-III survey in the Large Magellanic Cloud (LMC), in order to understand the formation mechanism and the characteristics of the parent population they came from. Methods. We used an updated theoretical pulsation scenario to derive the mass and the pulsation mode of each AC in the sample. We also used a Kolmogorov-Smirnov test to analyze the spatial distribution of the ACs, in comparison with that of other groups of variable stars, and connect their properties with the star formation history of the LMC. Results. We find that the mean mass of ACs is 1.2 \pm 0.2Mo. We show that ACs do not follow the same spatial distribution of classical Cepheids. This and the difference in their period-luminosity relations further support the hypothesis that ACs are not the extension to low luminosity of classical Cepheids. The spatial distribution of ACs is also different from that of bona-fide tracers of the old population, such as RR Lyrae stars and population II Cepheids. We therefore suggest that the majority of ACs in the LMC are made of intermediate-age (1-6Gyr), metal-poor single stars. Finally, we investigate the relation between the frequency of ACs and the luminosity of the host galaxy, disclosing that purely old systems follow a very tight relation and that galaxies with strong intermediate-age and young star formation tend to have an excess of ACs, in agreement with their hosting ACs formed via both single and binary star channels.

description: Background: Providing material benefits to increase access to healthy food (e.g., food coupons/vouchers, free food, or financial subsidies/incentives) for people with diabetes may be an effective healthcare intervention to improve food insecurity, dietary patterns, clinical parameters, and ultimately health outcomes. There are several studies that have investigated the impact of providing material benefits to improve food access among people with diabetes. There is also interest in Alberta, Canada in potentially implementing a healthy food prescription incentive for people with type 2 diabetes mellitus (T2DM) and food insecurity, which is being investigated in the “Food Rx” trial (NCT04725630). However, there has not been a systematic review or cost-effectiveness analysis on the impacts of providing material benefits to improve food access among people with diabetes. Thesis studies: a systematic review on the impacts of providing material benefits to improve food access on food insecurity, dietary patterns, and clinical parameters in people with diabetes; and a theoretical economic analysis to determine the minimum A1C improvement required for the Food Rx intervention to be cost-effective from the third-party healthcare payer perspective. Results: The systematic review showed that providing material benefits to improve food access for people with diabetes may improve household food insecurity, fruit and vegetable intake, and overall diet quality but is less likely to change clinical parameters and whole grain intake. The evidence from randomized controlled trials was limited to only six studies at high risk of bias, most commonly due to unblinded subjective outcomes measurement and high participant attrition. The economic threshold analysis showed that providing a healthy food prescription incentive to people with T2DM and food insecurity was unlikely to be cost-effective at $50,000/QALY, when projecting health outcomes from improvements in A1C and diabetes-related clinical parameters. Conclusion: The evidence of clinical effectiveness from providing material benefits to improve food access among people with T2DM is highly uncertain, and a healthy food prescription incentive for people with T2DM and food insecurity in Alberta has a low likelihood of cost-effectiveness, when measuring outcomes from improvements in diabetes-related clinical parameters
