Mexican migrant agricultural workers’ experiences of the public health measures during the COVID-19 pandemic in the Okanagan
Creators: name: Novoa Vignau, Maria Fernanda
Publisher: name: University of British Columbia
Year: 2023

description: Migrant agricultural workers (MAWs) play a key role in ensuring Canadian food security, with nearly half of these workers coming from Mexico. Extensive research reveals that MAWs in Canada face numerous barriers to access healthcare and face a high risk of health inequities, including substandard housing and hazardous working conditions. The COVID-19 pandemic exacerbated many of these health inequities, leading to some of the largest COVID-19 outbreaks outside long-term care facilities in Canada, along with the reported deaths of nine MAWs. Despite these critical issues, there is limited research exploring Mexican MAWs' barriers, facilitators and adverse effects associated with the pandemic response and its public health measures (PHM). To address this gap, this study focused on Mexican MAWs in the Okanagan region. The study employs community-based research using an interpretive description methodology and is guided by an intersectionality lens. The overarching question is as follows: What are the experiences of Mexican MAWs with PHM during the COVID-19 pandemic in the Okanagan region? Data were collected through field notes taken during volunteer work and individual semi-structured interviews with 14 Mexican MAWs, two healthcare professionals, and three support individuals. Interview transcripts and field notes were coded and subjected to thematic analysis using the NVivo software. Results of this study describe how pandemic responses failed to protect MAWs and to address the precarious conditions of Mexican MAWs, exacerbating avoidable inequities. The profound influence of deeply rooted structural factors that underpinned and perpetuated the health inequities experienced by Mexican MAWs throughout the pandemic are detailed as well as the invaluable role of community-based organizations in serving as crucial support for Mexican MAWs, and their significance as indispensable partners and pivotal allies to health authorities during times of crisis. These findings contribute to advancing knowledge and informing policy recommendations to address health inequities faced by Mexican MAWs, particularly in pandemic contexts, and add to growing calls for comprehensive policy reform of the Seasonal Workers Agricultural Program (SWAP).

description: Event DP-Ø23211-2 (hereafter referred to as DP23211) maize expresses the DvSSJ1 double-stranded RNA (DvSSJ1 dsRNA) and the IPD072Aa protein, encoded by the ipd072Aa gene. DvSSJ1 dsRNA and the IPD072Aa protein each provide control of corn rootworms (Diabrotica spp.) when expressed in plants. As part of the environmental risk assessment (ERA), the potential hazard to non-target organisms (NTOs) exposed to the DvSSJ1 dsRNA and the IPD072Aa protein expressed in DP23211 maize was assessed. Worst-case estimated environmental concentrations (EECs) for different NTO functional groups (pollinators and pollen feeders, soil dwelling detritivores, predators and parasitoids, aquatic detritivores, insectivorous birds, and wild mammals) were calculated using worst-case assumptions. Several factors that reduce exposure to NTOs under more realistic environmental conditions were applied, when needed to provide more environmentally relevant EECs. Laboratory bioassays were conducted to assess the activity of DvSSJ1 dsRNA or the IPD072Aa protein against selected surrogate species, and margins of exposure (MOEs) were calculated by comparing the Tier I hazard study results to worst-case or refined EECs. Based on specificity and MOE values, DvSSJ1 dsRNA and the IPD072Aa protein expressed in DP23211 maize are not expected to be harmful to NTO populations at environmentally relevant concentrations.

description: We study the phase space structure of the Jackiw-Teitelboim model in its connection variables formulation where the gauge group of the field theory is given by local SL(2,R) (or SU(2) for the Euclidean model), i.e. the de Sitter group in two dimensions. In order to make the connection with two dimensional gravity explicit, a partial gauge fixing of the de Sitter symmetry can be introduced that reduces it to spacetime diffeomorphisms. This can be done in different ways. Having no local physical degrees of freedom, the reduced phase space of the model is finite dimensional. The simplicity of this gauge field theory allows for studying different avenues for quantization, which may use various (partial) gauge fixings. We show that reduction and quantization are noncommuting operations: the representation of basic variables as operators in a Hilbert space depend on the order chosen for the latter. Moreover, a representation that is natural in one case may not even be available in the other leading to inequivalent quantum theories.

description: Objective: The presence of cervical lymph node metastasis is an important prognostic factor for patients with head and neck squamous cell carcinomas (HNSCC). Accurate assessment of lymph node metastasis in these patients is essential for appropriate management and for prognostic and management purposes. Here, we evaluated the effectiveness of the maximum standardized uptake value (SUVmax) on positron emission tomography (PET) in assessing lymph node metastasis in head and neck squamous cell carcinomas prior to surgery.
 Methods: A retrospective review of 74 patients with HNSCC who underwent PET/CT prior to neck dissection were examined. Pre-operative PET/CT scans were reviewed by a single, experienced nuclear medicine physician and SUVmax of the largest node in each nodal basin documented. These were compared with the histology results of the neck dissection.
 Results: A total of 364 nodal basins including 86 basins with metastatic nodes were evaluated. A nodal SUVmax ≥3.16 yielded a sensitivity of 74.4% and specificity of 84.9% in detecting metastatic nodes. The ratio between nodal SUVmax and liver SUVmax was found on receiver operating characteristic (ROC) to be effective in detecting metastatic nodes with an area under ROC curve of 0.90. A nodal SUVmax /Liver SUVmax ratio ≥0.90 yielded a sensitivity of 74.1% and specificity of 93.4%.
 Conclusions: Nodal SUVmax and nodal SUVmax/ liver SUVmax are both useful in the pre-operative detection of metastatic nodes. The latter is likely to be more useful as it corrects for inter-scanner variability.

description: Motivated by the growing consumer interest in new energy vehicles, this paper studies a manufacturer's pricing and channel selection issues when selling green products to environmentally conscious consumers. Three channel structures are examined: (1) a single agency selling channel, (2) a single reselling channel, and (3) dual channels of agency selling and reselling. Agency selling refers to the case in which the manufacturer directly sells products to consumers on the platform by paying a fixed fee. Reselling refers to when the manufacturer wholesales products to the platform, which is then responsible for selling to end consumers. We find that an increase in consumers' green awareness has a positive impact on green technology levels, retail prices, and the profits of the manufacturer, platform, and retailer. When consumers' green awareness and the revenue-sharing rate are relatively low, the manufacturer will choose the single reselling channel, which is beneficial for both the manufacturer and retailer. When consumers' green awareness is moderate, the manufacturer will choose the hybrid channel in which the manufacturer and platform will reach a win-win situation. When consumers' green awareness is high, the dual channel is simultaneously beneficial for the manufacturer, platform, and retailer, which reveals that Pareto optimisation occurs.

description: We present first-principles, density-functional theory calculations of the NMR chemical shifts for polycyclic aromatic hydrocarbons, starting with benzene and increasing sizes up to the one- and two-dimensional infinite limits of graphene ribbons and sheets. Our calculations are performed using a combination of the recently developed theory of orbital magnetization in solids, and a novel approach to NMR calculations where chemical shifts are obtained from the derivative of the orbital magnetization with respect to a microscopic, localized magnetic dipole. Using these methods we study on equal footing the $^1$H and $^{13}$C shifts in benzene, pyrene, coronene, in naphthalene, anthracene, naphthacene, and pentacene, and finally in graphene, graphite, and an infinite graphene ribbon. Our results show very good agreement with experiments and allow us to characterize the trends for the chemical shifts as a function of system size.

description: When genetically modified (GM) maize is planted in an open field, it may cross-pollinate with the nearby non-GM maize under certain airflow conditions. Suitable sampling methods are crucial for tracing adventitious GM content. By using field data and bootstrap simulation, we evaluated the performance of common sampling schemes to determine the adventitious GM content in small maize fields in Taiwan. A pollen dispersal model that considered the effect of field borders, which are common in Asian agricultural landscapes, was used to predict the cross-pollination (CP) rate. For the 2009–1 field data, the six-transect (Tsix), JM method for low expected flow (JM[L]), JM method for high expected flow (JM[H]), and V-shaped transect (TV) methods performed comparably to simple random sampling (SRS). Tsix, TV, JM(L), and JM(H) required only 13% or less of the sample size required by SRS. After the simulation and verification of the 2009–2 and 2010–1 field data, we concluded that Tsix, TV, JM(L), and systematic random sampling methods performed equally as well as SRS in CP rate predictions. Our findings can serve as a reference for monitoring the pollen dispersal tendencies of maize in countries with smallholder farming systems.
Enhancing post-harvest regeneration monitoring with digital aerial photogrammetry and deep learning

Publisher: name: University of British Columbia

description: Surveys to monitor forest regeneration are vital for ensuring sustainable forest management and informing long-term timber supply but are often challenged by high costs, safety, and availability of qualified field crews. Advances in fine spatial resolution imagery and digital aerial photogrammetry have enabled detailed 3D mapping of individual regenerating trees. Deep learning, utilizing convolutional neural networks like Mask R-CNN, offers high accuracy and automation for deriving regeneration survey data. This dissertation explores, in Alberta, Canada, automating the acquisition and analysis of regeneration survey data using these technologies. To do so, a Mask R-CNN model was trained to accurately delineate 85% of coniferous tree crowns across different growth conditions. I then derived photogrammetric height measurements that were strongly correlated with field measurements (r2 = 0.93, RMSE = 0.34 m). I then assessed the potential of near-infrared versus conventional optical imagery for the species classification of delineated lodgepole pine (Pinus contorta) and white spruce (Picea glauca) crowns, concluding that conventional optical imagery was suitable for this task. Using this optical imagery, I then applied transfer learning to extend the crown delineation model to instead delineate and classify crown species simultaneously, achieving a mAP of 0.72 and class F1 scores of 0.69 for lodgepole pine and 0.78 for white spruce. Additional fine-tuning on new data showed a potential for further improvement. To support long-term planning, I then developed a methodology to integrate these derived attributes with Alberta's existing growth and yield model. Despite some discrepancies between initial conditions estimated by these methods and conventional field-based surveys, the trajectories and end points of the growth and yield predictions of these datasets were comparable. This research demonstrates the feasibility of these methods and provides guidelines and recommendations for operational implementation, contributing towards more efficient and sustainable forest management in Alberta.

description: Using the tight-binding approximation and the nonequilibrium Green's function approach, we investigate the coherent spin-dependent transport in planar magnetic junctions consisting of two ferromagnetic (FM) electrodes separated by a graphene flake (GF) with zigzag or armchair interfaces. It is found that the electron conduction strongly depends on the geometry of contact between the GF and the FM electrodes. In the case of zigzag interfaces, the junction demonstrates a spin-valve effect with high magnetoresistance (MR) ratios and shows negative differential resistance features for a single spin channel at positive gate voltage. In the case of armchair interfaces, the current-voltage characteristics behave linearly at low bias voltages and hence, both spin channels are in on state with low MR ratios.

description: The high-entropy concept was applied to the synthesis of transition-metal antimonides, M1-xPtxSb (M = equimolar Ru, Rh, Pd, and Ir). High-entropy antimonide samples crystallized in a pseudo-hexagonal NiAs-type crystal structure with a P63/mmc space group were successfully synthesized through a conventional solid-state reaction and subsequent quenching. A detailed investigation of the composition and equilibration conditions confirmed the reversible phase transition between a multi-phase state at low temperature and an entropy-driven single-phase solid solution at high temperatures. Electrical resistivity, magnetization, and heat capacity measurements of single-phase M1-xPtxSb (x = 0.2) samples revealed a bulk superconducting transition at 2.15(2) K. This study demonstrates that the high-entropy concept provides numerous opportunities for the discovery of new functional materials such as superconductors.

description: The development of technology starts with the greatest advantage and massive disadvantage. One of its disadvantages is with the growth in home Personal Computer (PC) usage and the more readily available access to the World Wide Web over the past decade, child pornographers have found a convenient venue for sharing horrific pictures and videos of children being sexually abused. The method used by the police and law enforcement to solve this problem is like searching for needles in a haystack or other words it may be considered to be primitive and inefficient. In this paper, we discuss the technical issue faced by the user who surfs on the internet then ends up with illegal things. Then how children get stuck with pornography. We also propose a new solution for eliminating the hashtags of the child pornography content and to link the physical data are collected with the help of technology to search for the victim. We are trying to implement this method and we believe in our method which will bring a complete end to this cruelty and can be implemented easily and executed faster than other means to a solution. We are trying to make sure that “Let kids be kids”.

description: The outbreak of the novel coronavirus, COVID-19, has become one of the most severe pandemics in human history. In this paper, we propose to leverage social media users as social sensors to simultaneously predict the pandemic trends and suggest potential risk factors for public health experts to understand spread situations and recommend proper interventions. More precisely, we develop novel deep learning models to recognize important entities and their relations over time, thereby establishing dynamic heterogeneous graphs to describe the observations of social media users. A dynamic graph neural network model can then forecast the trends (e.g. newly diagnosed cases and death rates) and identify high-risk events from social media. Based on the proposed computational method, we also develop a web-based system for domain experts without any computer science background to easily interact with. We conduct extensive experiments on large-scale datasets of COVID-19 related tweets provided by Twitter, which show that our method can precisely predict the new cases and death rates. We also demonstrate the robustness of our web-based pandemic surveillance system and its ability to retrieve essential knowledge and derive accurate predictions across a variety of circumstances. Our system is also available at http://scaiweb.cs.ucla.edu/covidsurveiller/.This article is part of the theme issue ‘Data science approachs to infectious diseases surveillance’.

description: Over the past two decades, helioseismology has revolutionized our understanding of the interior structure and dynamics of the Sun. Asteroseismology will soon place this knowledge into a broader context by providing structural data for hundreds of Sun-like stars. Solar-like oscillations have already been detected from the ground in several stars, and NASA's Kepler mission is poised to unleash a flood of stellar pulsation data. Deriving reliable asteroseismic information from these observations demands a significant improvement in our analysis methods. In this paper we report the initial results of our efforts to develop an objective stellar model-fitting pipeline for asteroseismic data. The cornerstone of our automated approach is an optimization method using a parallel genetic algorithm. We describe the details of the pipeline and we present the initial application to Sun-as-a-star data, yielding an optimal model that accurately reproduces the known solar properties.

description: We present data from the archival plates at Harvard College Observatory and Sonneberg Observatory showing the field of the solar type pre-main sequence star GM Cep. A total of 186 magnitudes of GM Cep have been measured on these archival plates, with 176 in blue sensitivity, 6 in visible, and 4 in red. We combine our data with data from the literature and from the American Association of Variable Star Observers to depict the long-term light curves of GM Cep in both B and V wavelengths. The light curves span from 1895 until now, with two densely sampled regions (1935 to 1945 in B band, and 2006 until now in V band). The long-term light curves do not show any fast rise behavior as predicted by an accretion mechanism. Both the light curves and the magnitude histograms confirm the conclusion that the light curves are dominated by dips (possibly from extinction) superposed on some quiescence state, instead of outbursts caused by accretion flares.Our result excludes the possibility of GM Cep being a FUor, EXor, or McNeil's Nebula type star. Several special cases of T Tauri stars were checked, but none of these light curves are compatible with that of GM Cep. The lack of periodicity in the light curve excludes the possibility of GM Cep being a KH 15D system.

description: As space-faring nations across the globe are fueling a new race of human space exploration that goes well beyond the Moon, national agencies and private entities across the globe have accelerated the research and development that will promote the safety and success of such missions. Prolonged body unloading and reduced physical activity levels associated with space travel could adversely affect brain and behavior. Long-duration bed rest in –6° head-down tilt (>1 month) is an established spaceflight analog on Earth to simulate the physiological and psychological adaptations of prolonged inactivity and headward fluid shift during space travel. The present work investigated the effects of long-duration bed rest on brain function and cognitive performance. In a series of five studies combining behavioral, electrocortical and magnetic resonance imaging data it was shown that bed rest can induce significant functional brain changes and cognitive impairments including emotion processing, memory formation, and selective attention, and that these effects may not recover quickly. Structured physical activity programs superimposed to bed rest were found to mitigate cognitive impairments. The benefits of antioxidant supplementation and artificial gravity or their combination with exercise remain to be determined. Some caution is warranted when behavioral data are collected in different body positions, i.e., seated vs. head-down tilt, because the neurophysiological reactions associated with postural changes may mask the effects attributed to physical inactivity. Future work in this field should be characterized by an interdisciplinary approach, integrating multimodal brain imaging, psychological and behavioral, neurovestibular, cardiovascular, biochemical, and circadian data. Such an approach could promote a holistic understanding of intellectual frameworks that together exceed individual disciplinary perspectives. The knowledge from such approaches could go beyond their application to spaceflight. It can translate to the prevention and treatment of various clinical conditions associated with cognitive impairments, and for which reduced physical activity levels are a critical risk factor.

description: We conducted an extensive computational experiment, lasting multiple CPU-years, to optimally select parameters for two important classes of algorithms for finding sparse solutions of underdetermined systems of linear equations. We make the optimally tuned implementations available at {\tt sparselab.stanford.edu}; they run `out of the box' with no user tuning: it is not necessary to select thresholds or know the likely degree of sparsity. Our class of algorithms includes iterative hard and soft thresholding with or without relaxation, as well as CoSaMP, subspace pursuit and some natural extensions. As a result, our optimally tuned algorithms dominate such proposals. Our notion of optimality is defined in terms of phase transitions, i.e. we maximize the number of nonzeros at which the algorithm can successfully operate. We show that the phase transition is a well-defined quantity with our suite of random underdetermined linear systems. Our tuning gives the highest transition possible within each class of algorithms.

description: Background: The prevalence of food allergy (FA) among European school children is poorly defined. Estimates have commonly been based on parent-reported symptoms. We aimed to estimate the frequency of FA and sensitization against food allergens in primary school children in eight European countries. Methods: A follow-up assessment at age 6-10 years of a multicentre European birth cohort based was undertaken using an online parental questionnaire, clinical visits including structured interviews and skin prick tests (SPT). Children with suspected FA were scheduled for double-blind, placebo-controlled oral food challenges (DBPCFC). Results: A total of 6105 children participated in this school-age follow-up (57.8% of 10 563 recruited at birth). For 982 of 6069 children (16.2%), parents reported adverse reactions after food consumption in the online questionnaire. Of 2288 children with parental face-to-face interviews and/or skin prick testing, 238 (10.4%) were eligible for a DBPCFC. Sixty-three foods were challenge-tested in 46 children. Twenty food challenges were positive in 17 children, including seven to hazelnut and three to peanut. Another seventy-one children were estimated to suffer FA among those who were eligible but refused DBPCFC. This yielded prevalence estimates for FA in school age between 1.4% (88 related to all 6105 participants of this follow-up) and 3.8% (88 related to 2289 with completed eligibility assessment). Interpretation: In primary school children in eight European countries, the prevalence of FA was lower than expected even though parents of this cohort have become especially aware of allergic reactions to food. There was moderate variation between centres hampering valid regional comparisons.

Knowledge, attitudes, and behaviours toward support resources among first-year students at a Canadian dental school
Creators: name: Nguyen, Kristie
Publisher: name: University of British Columbia
Year: 2023

description: Objectives: This study investigated the attitudes, knowledge, and behaviours of first-year Doctor of Dental Medicine (DMD) students toward existing student support resources within the University of British Columbia (UBC)’s Faculty of Dentistry (FoD) and the additional resources needed from the student perspective to inform the development of student support programming. Methods: An online survey was distributed to all 59 first-year DMD students in April 2022. This survey included three parts: 1) demographics; 2) Likert-scale questions inquiring about the perception and utilization of available support resources; and 3) open-ended questions exploring academic and non-academic experiences. A focus group with 5 students followed in May 2022 to further explore the themes emerging from the survey. Results: Forty-six (46) students participated in the survey for a 78% response rate. Survey findings revealed that most student respondents (70%) were familiar with FoD support resources, but only a quarter (24%) of respondents accessed them. Few (26%) were familiar with resources across UBC, and most (98% of total respondents) did not access them. Some (26%) felt stigma prevented them from accessing resources within and outside the FoD. More respondents who identified with the pronouns she/her knew who to contact for academic support in comparison to respondents who identified with the pronouns he/him (70% vs. 53%; P=0.029). No statistical significance was found between age and utilization of resources (P=0.071). Survey themes that emerged from qualitative analysis included: challenges with transitioning into a professional program, imposter syndrome, stigmatization of accessing resources, suggestions for increasing mentorship with senior DMD students, and unfamiliarity with existing resources. Focus group respondents elaborated on their experiences and challenges, including recommendations for further support for student needs. Conclusion: Grounded in the student voice, this study informs future support programming and development of student support systems at UBC and other institutions. Recommendations include improving awareness of the availability and purpose of support resources within the FoD, and expanding peer mentorship opportunities to include senior DMD students.
Results in Kalb-Ramond field localization and resonances on deformed branes

description: We make an analysis about several aspects of localization of the Kalb-Ramond gauge field in a specific four dimensional AdS membrane embedded in a five dimensional space-time. The membrane is generated from a deformation of the $λϕ^4$ potential and belongs to a new class of defect solutions. In this context we find resonance structures in the analysis of massive modes. The study of deformed defects is important because they contain internal structures and these may have implications to the way the background space-time is constructed and the way its curvature behaves. The main objective here is to observe the contributions of the deformation procedure to the resonances and the well known field localization methods.

description: The characterisation of the stellar population toward young high-mass star-forming regions allows to constrain fundamental cluster properties like distance and age. These are essential when using high-mass clusters as probes to conduct Galactic studies. NGC 7538 is a star-forming region with an embedded stellar population only unearthed in the near-infrared. We present the first near-infrared spectro-photometric study of the candidate high-mass stellar content in NGC 7538. We obtained H and K spectra of 21 sources with both the multi-object and long-slit modes of LIRIS at the WHT, and complement these data with sub-arcsecond JHKs photometry of the region using the imaging mode of the same instrument. We find a wide variety of objects within the studied stellar population of NGC 7538. Our results discriminate between a stellar population associated to the HII region, but not contained within its extent, and several pockets of more recent star formation. We report the detection of CO bandhead emission toward several sources as well as other features indicative of a young stellar nature. We infer a spectro-photometric distance of 2.7+-0.5 kpc, an age spread in the range 0.5-2.2 Myr and a total mass ~1.7x10^3 Msun for the older population.

description: Transgender and gender nonconforming (TGNC) individuals, estimated to surpass 1.6 million in the United States alone, encounter significant disparities in accessing comprehensive healthcare, including reproductive services. Certified Nurse Midwives (CNMs), pivotal in primary reproductive health care delivery, are uniquely positioned to address these disparities, particularly in underserved settings such as Federally Qualified Health Centers and rural areas. However, TGNC individuals face multifaceted barriers to general and reproductive healthcare, stemming from structural, interpersonal, and individual-level factors. These barriers include elevated rates of sexually transmitted infections (STIs), reluctance to seek sexual and reproductive health services, and encounters with uninformed or unwelcoming providers. Furthermore, accessing care necessitates disclosing intimate details and potentially outing oneself, adding layers of complexity to an already challenging process. This review explores the unique healthcare needs of TGNC individuals, emphasizing the crucial role CNMs can play in mitigating disparities and fostering inclusive and affirming reproductive healthcare environments

description: Gestational diabetes mellitus (GDM) is a common metabolic disease associated with maternal and foetal complications; gut microbiome might participate in GDM pathogenesis. Possible biological links include short chain fatty acids, incretin hormones, bile acids homeostasis and peroxisome proliferator-activated receptor gamma deficiency. Gut microbiome differs in patients with GDM even in early pregnancy, but no differences are observed five years postpartum. Patients have enriched Verrucomicrobia phylum, Christensenellaceae and Lachnospiraceae families, Haemophilus, Prevotella, Actinomyces, Collinsella and Ruminococcus genera during pregnancy. Clostridiales order, Alistipes, Faecalibacterium, Blautia, Eubacterium and Roseburia genera are depleted. However, there is great heterogeneity in the reviewed studies and scientific data on the use of gut microbiome characteristics and related biomarkers in GDM risk stratification and diagnosis are scarce. Probiotics and synbiotics have been tested for prevention and treatment for GDM with limited efficacy. Future studies should explore the effect of probiotics administration at first trimester of pregnancy and their value as adjuvant therapy.
