description: Basic equations of diffusional kinetics in alloys are statistically derived using the master equation approach. To describe diffusional transformations in substitution alloys, we derive the "quasi-equilibrium" kinetic equation which generalizes its earlier versions by taking into account possible "interaction renormalization" effects. For the interstitial alloys Me-X, we derive the explicit expression for the diffusivity D of an interstitial atom X which notably differs from those used in previous phenomenological treatments. This microscopic expression for D is applied to describe the diffusion of carbon in austenite basing on some simple models of carbon-carbon interaction. The results obtained enable us to make certain conclusions about the real form of these interactions, and about the scale of the "transition state entropy" for diffusion of carbon in austenite.

Static and dynamic variational principles for strongly correlated electron systems
Creators: name: Potthoff, Michael
Publisher: name: arXiv
Year: 2012
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The equilibrium state of a system consisting of a large number of strongly interacting electrons can be characterized by its density operator. This gives a direct access to the ground-state energy or, at finite temperatures, to the free energy of the system as well as to other static physical quantities. Elementary excitations of the system, on the other hand, are described within the language of Green's functions, i.e. time- or frequency-dependent dynamic quantities which give a direct access to the linear response of the system subjected to a weak time-dependent external perturbation. A typical example is angle-revolved photoemission spectroscopy which is linked to the single-electron Green's function. Since usually both, the static as well as the dynamic physical quantities, cannot be obtained exactly for lattice fermion models like the Hubbard model, one has to resort to approximations. Opposed to more ad hoc treatments, variational principles promise to provide consistent and controlled approximations. Here, the Ritz principle and a generalized version of the Ritz principle at finite temperatures for the static case on the one hand and a dynamical variational principle for the single-electron Green's function or the self-energy on the other hand are introduced, discussed in detail and compared to each other to show up conceptual similarities and differences. In particular, the construction recipe for non-perturbative dynamic approximations is taken over from the construction of static mean-field theory based on the generalized Ritz principle. Within the two different frameworks, it is shown which types of approximations are accessible, and their respective weaknesses and strengths are worked out. Static Hartree-Fock theory as well as dynamical mean-field theory are found as the prototypical approximations.

Aboriginal people in a time of disorder : exploring indigenous interactions with justice in Colombia
Creators: name: Gomez-Isaza, Lina Maria
Publisher: name: University of British Columbia
Year: 2010

description: This study of law and aboriginal people in Colombia builds on the premise that law is a form of local knowledge and that state law is reshaped locally, producing outcomes unanticipated by the state itself. Comaroff’s (2001) idea of lawfare, in which the state uses a legal regime to erode local autonomy, reflects the current reality in Colombia, but this notion does not explain this situation entirely. My data come from interviews with aboriginal leaders, experience as a public servant and reading of academic and popular literature. This case study of the Justice and Peace Law of 2005 examines legal processes of the state and aboriginal communities’ public responses to the state and their own internal debates and processes. In the end, I was able to explore the intersection of the state and aboriginal people. Colombia’s unique violence, product of political struggles and economical interests, was supposed to disrupt society has, paradoxically, strengthened community ties. I have drawn three major conclusions to my argument. First, the passage of the JPL has inadvertently strengthened solidarity amongst the Embera – Chamí and other aboriginal groups. Second, this strengthening of solidarity has itself increased indigenous identity; and third, aboriginal justice practices have been transformed and solidified. This too has strengthened community cohesion.
Bayesian Calibration for Logit Model Microsimulations: Case for PECAS SD in San Diego

description: Bayesian inference is a versatile method for incorporating new information into a model while still respecting existing knowledge. One application of Bayesian inference is the calibration of models that are controlled by a large number of parameters, but where the data usable for calibration is incomplete or unreliable. Microsimulation models of urban development fit both of these criteria, but calibrating them is further complicated by their non-determinism. I investigated a calibration method called Bayesian Expected Value Calibration, which is designed to overcome non-determinism while incorporating existing knowledge, in the context of the PECAS Space Development model of the San Diego area. The test consisted of creating synthetic data using known behavioural parameters, calibrating the Space Development model to targets derived from the synthetic data and with priors reflecting imperfect existing knowledge, and assessing how closely the calibrated parameters matched the true values. I found that BEVC was generally effective at converging towards the true values of the parameters, and often received meaningful contributions from both the prior knowledge and the new observations under a range of plausible conditions. As would be expected from Bayesian theory, increasing the number of observations or the amount of useful prior knowledge improved the accuracy of the calibration. The method was robust under reasonable levels of human fallibility in creating the priors, and only suffered from significant loss of accuracy under extreme assumptions. However, more sophisticated methods of objectively determining the weights to assign to the data sources did not significantly improve calibration accuracy.

description: The B[e] phenomenon is manifested by a heterogeneous group of stars surrounded by gaseous and dusty circumstellar envelopes with similar physical conditions. Among these stars, the FS CMa-type objects are suspected to be binary systems, which could be experiencing or have undergone a mass-transfer process that could explain the large amount of material surrounding them. We aim to contribute to the knowledge of a recently confirmed binary, MWC 645, which could be undergoing an active mass-transfer process. We present near-infrared and optical spectra, identify atomic and molecular spectral features, and derive different quantitative properties of line profiles. Based on publicly available photometric data, we search for periodicity in the light curve and model the spectral energy distribution. We have detected molecular bands of CO in absorption at 1.62 $μ$m and 2.3 $μ$m for the first time. We derive an upper limit for the effective temperature of the cool binary component. We found a correlation between the enhancement of the H$α$ emission and the decrease in optical brightness that could be associated with mass-ejection events or an increase in mass loss. We outline the global properties of the envelope, possibly responsible for brightness variations due to a variable extinction, and briefly speculate on different possible scenarios.

description: In the light of the recent LHC data on proton-proton and lead-lead collisions we examine the question of the multiplicity scaling of HBT radii in relativistic nuclei and particle interactions. Within the UrQMD transport approach we study a large variety of system sizes at different beam energies and extract the HBT radii. In the calculation, we find a good scaling of the radii as a function of charged particle multiplicity, if the change in the multiplicity is caused by a change of centrality at the same energy. However, the scaling is only approximate when the energy, $\sqrt{s}$, is changed and breaks down when comparing pp to AA reactions.

description: Many IoT use cases demand both secure storage and secure communication. Resource-constrained devices cannot afford having one set of crypto protocols for storage and another for communication. Lightweight application layer security standards are being developed for IoT communication. Extending these protocols for secure storage can significantly reduce communication latency and local processing. We present BLEND, combining secure storage and communication by storing IoT data as pre-computed encrypted network packets. Unlike local methods, BLEND not only eliminates separate crypto for secure storage needs, but also eliminates a need for real-time crypto operations, reducing the communication latency significantly. Our evaluation shows that compared with a local solution, BLEND reduces send latency from 630 microseconds to 110 microseconds per packet. BLEND enables PKI based key management while being sufficiently lightweight for IoT. BLEND doesn't need modifications to communication standards used when extended for secure storage, and can therefore preserve underlying protocols' security guarantees.

description: This thesis investigates psychological distress in Emergency Medical Services practitioners through three pieces of inter-related research. The first examines the prevalence of compassion fatigue in all health care practitioners by systematic review of literature. The second conceptualizes three manifestations of distress (compassion fatigue, burnout, and post-traumatic stress disorder), places them in the context of EMS work by describing practitioners’ experience, and broadly strategizes ways to address them. The third measures the presence of compassion fatigue, burnout, and post-traumatic stress disorder in a sample of EMS practitioners through a survey based study. Overall, the research showed that EMS practitioners are experiencing psychological distress as compassion fatigue, burnout and PTSD, and that compassion fatigue has been identified across diverse practitioner groups in health care. Recommendations are consistently made that further research needs to be conducted to investigate root causes, and that education and support programs would be of benefit to practitioners.

description: Many inverse problems include nuisance parameters which, while not of direct interest, are required to recover primary parameters. Structure present in these problems allows efficient optimization strategies - a well known example is variable projection, where nonlinear least squares problems which are linear in some parameters can be very efficiently optimized. In this paper, we extend the idea of projecting out a subset over the variables to a broad class of maximum likelihood (ML) and maximum a posteriori likelihood (MAP) problems with nuisance parameters, such as variance or degrees of freedom. As a result, we are able to incorporate nuisance parameter estimation into large-scale constrained and unconstrained inverse problem formulations. We apply the approach to a variety of problems, including estimation of unknown variance parameters in the Gaussian model, degree of freedom (d.o.f.) parameter estimation in the context of robust inverse problems, automatic calibration, and optimal experimental design. Using numerical examples, we demonstrate improvement in recovery of primary parameters for several large- scale inverse problems. The proposed approach is compatible with a wide variety of algorithms and formulations, and its implementation requires only minor modifications to existing algorithms.

description: This paper investigates the impact of LiDAR configuration shifts on the performance of 3D LiDAR point cloud semantic segmentation models, a topic not extensively studied before. We explore the effect of using different LiDAR channels when training and testing a 3D LiDAR point cloud semantic segmentation model, utilizing Cylinder3D for the experiments. A Cylinder3D model is trained and tested on simulated 3D LiDAR point cloud datasets created using the Mississippi State University Autonomous Vehicle Simulator (MAVS) and 32, 64 channel 3D LiDAR point clouds of the RELLIS-3D dataset collected in a real-world off-road environment. Our experimental results demonstrate that sensor and spatial domain shifts significantly impact the performance of LiDAR-based semantic segmentation models. In the absence of spatial domain changes between training and testing, models trained and tested on the same sensor type generally exhibited better performance. Moreover, higher-resolution sensors showed improved performance compared to those with lower-resolution ones. However, results varied when spatial domain changes were present. In some cases, the advantage of a sensor's higher resolution led to better performance both with and without sensor domain shifts. In other instances, the higher resolution resulted in overfitting within a specific domain, causing a lack of generalization capability and decreased performance when tested on data with different sensor configurations.

description: Acoustic impedance is a rock property that can be derived from seismic data and contains important information about subsurface properties. Mathematically, the acoustic impedance can be calculated from earth’s reflectivity function and this function can be estimated from seismic data. However, estimation of reflectivity from seismic data even after excellent data processing, is always very bandlimited, lacking both low and high frequencies. In this situation, recovering any of this bandwidth, especially low frequencies, can be helpful. The thesis will be focused on recovering low frequencies to improve impedance estimation and this includes trying to improve a frequency domain deconvolution algorithm using different smoother types and correcting the whitening error of deconvolution operator using color operator. At the end, the maximum correlation results between acoustic impedance inversion and well impedance demonstrate using color operator can increase the maximum correlation by around 20 percent comparing with the result without using color operator.

description: Abstract: - This systematic review explores the applications of High-Performance Computing (HPC) in AI-driven disease prediction models, emphasizing the role of machine learning (ML) and deep learning (DL) algorithms in advancing healthcare diagnostics. HPC, by enabling rapid data processing and complex simulations, has become indispensable in analyzing large-scale medical data, such as genomic sequencing, biomedical imaging, and electronic health records (EHRs). Through the application of AI, particularly ML and DL models, healthcare systems can achieve more accurate disease predictions and personalized treatment strategies. These models, which learn from vast amounts of medical records and images, improve over time, becoming more precise in diagnosing conditions such as cancer and diabetes. This review assesses the effectiveness, scalability, and practical applications of HPC and AI in healthcare diagnostics, including drug discovery and disease progression modeling. We conducted a comprehensive literature search in multiple databases, including PubMed, Scopus, and IEEE Xplore, focusing on studies published between 2020 and 2025. After applying inclusion and exclusion criteria, 600 relevant studies were selected. The findings underscore the transformative potential of HPC and AI in healthcare, highlighting the accuracy and efficiency these technologies offer in disease prediction and treatment. Future research should focus on enhancing unsupervised learning algorithms and integrating HPC-enabled AI solutions into automated healthcare delivery systems, such as those supported by 5G networks and advanced neural networks. This review provides a critical overview of current advancements and sets the stage for further innovations in AI-driven healthcare diagnostics.

description: Among various definitions of quantum correlations, quantum discord has attracted considerable attention. To find analytical expression of quantum discord is an intractable task. In this paper, we discuss thoroughly the case of two-qubit rank-two states. An analytical expression for the quantum discord is obtained by means of Koashi-Winter relation. A geometric picture is demonstrated by means of quantum steering ellipsoid. We point out that in this case the optimal measurement is indeed the von Neumann measurement, which is usually used in the study of quantum discord. However, for some two-qubit states with the rank larger than two, we find that three-element POVM measurement is more optimal. It means that more careful attention should be paid in the discussion of quantum discord.

description: We investigate the problem of packing identical hard objects on regular lattices in d dimensions. Restricting configuration space to parallel alignment of the objects, we study the densest packing at a given aspect ratio X. For rectangles and ellipses on the square lattice as well as for biaxial ellipsoids on a simple cubic lattice, we calculate the maximum packing fraction ϕ_d(X). It is proved to be continuous with an infinite number of singular points X^{\rm min}_ν, X^{\rm max}_ν, ν=0, \pm 1, \pm 2,... In two dimensions, all maxima have the same height, whereas there is a unique global maximum for the case of ellipsoids. The form of ϕ_d(X) is discussed in the context of geometrical frustration effects, transitions in the contact numbers and number theoretical properties. Implications and generalizations for more general packing problems are outlined.

The Role of Stress in Recovery of Function After Spinal Cord Injur

subject: SCI

description: Neurotrauma patients frequently suffer from stress both acutely and chronically following the injury. However, little is understood regarding the impact of stress on recovery of function following spinal cord injury (SCI). The hypothesis for this thesis is that stress will reduce functional recovery from SCI. The first aim of this thesis was to develop a chronic unpredictable stress paradigm. Three measurements were used to verify its effectiveness, circulating corticosteroid levels, weight of adrenal glands and performance in the open field. In aim 2, the effect of stress on locomotor performance was assessed in uninjured mice. Stress did not affect performance on any of the behavioural assays used. The final aim was to assess the effects of stress on recovery from SCI. The Basso Mouse Scale was used to assess recovery which showed that stress negatively influenced scores. These data suggest that chronic stress reduces functional recovery from spinal cord injury.

Wood property relationships and survival models in reliability
Creators: name: Cheng, Yan
Publisher: name: University of British Columbia
Year: 2010

description: It has been a topic of great interest in wood engineering to understand the relationships between the different strength properties of lumber and the relationships between the strength properties and covariates such as visual grading characteristics. In our mechanical wood strength tests, each piece fails (breaks) after surviving a continuously increasing load to a level. The response of the test is the wood strength property -- load-to-failure, which is in a very different context from the standard time-to-failure data in Biostatistics. This topic is also called reliability analysis in engineering. In order to describe the relationships among strength properties, we develop joint and conditional survival functions by both a parametric method and a nonparametric approach. However, each piece of lumber can only be tested to destruction with one method, which makes modeling these joint strengths distributions challenging. In the past, this kind of problem has been solved by subjectively matching pieces of lumber, but the quality of this approach is then an issue. We apply the methodologies in survival analysis to the wood strength data collected in the FPInnovations (FPI) laboratory. The objective of the analysis is to build a predictive model that relates the strength properties to the recorded characteristics (i.e. a survival model in reliability). Our conclusion is that a type of wood defect (knot), a lumber grade status (off-grade: Yes/No) and a lumber's module of elasticity (moe) have statistically significant effects on wood strength. These significant covariates can be used to match pieces of lumber. This paper also supports use of the accelerated failure time (AFT) model as an alternative to the Cox proportional hazard (Cox PH) model in the analysis of survival data. Moreover, we conclude that the Weibull AFT model provides a much better fit than the Cox PH model in our data set with a satisfying predictive accuracy.
Ultra-high field enhancing in Split Ring Resonators by azimuthally polarized excitation

description: We study the field enhancement and resonance frequencies in split-ring resonators (SRR) illuminated by azimuthally polarized light. We find that compared to linearly polarized illumination, the azimuthally polarized illumination increase the intensity enhancement by more than an order of magnitude. We attribute the increase in the intensity enhancement to the improved overlap between the SRR geometry and the direction of the electric field vector in each point. In addition, we present and explore a method to tune the resonance frequency of the SRR (for azimuthal polarization) by introducing more gaps to the structure. This approach allows for simple and straightforward tuning of the resonance frequency with small impact on the intensity enhancement. The impact of the design parameters on the intensity enhancement under azimuthally polarized illumination is also studied in details, exhibiting clear differences to the case of linear polarized illumination.

description: We study the single-particle density of states of one-dimensional and two-dimensional quantum disordered systems with long-range interactions. We consider a $1/\sqrt{r}$ interaction in one dimension and a Coulomb interaction in two dimensions, which produce linear gaps in the density of states in both cases. We focus on the strong localization regime where the localization length is small but non-zero. We use an exact diagonalization technique for small system sizes and a perturbation approach for larger sizes. We find that, with both methods, the inclusion of a finite hopping contribution does not change the linear character of the gap, but reduces its slope, widening the gap.

Bridging the Gap: When Mid-career Teachers Transition from Traditional to Multiage Contexts: Lessons from the Field

description: The purpose of this study was to describe and analyze from a cultural perspective the complex interaction of individual, organizational, and contextual influences on the development of mid-career teachers’ professional identity as they transitioned from traditional to multiage contexts. The following questions were answered: What do teachers perceive as their greatest challenges and opportunities in making the transition to a multiage classroom? Do these perceptions change over time? Do the teachers’ beliefs and perceptions match their actions and practices? What supports were put in place for teachers making the transition from traditional contexts to multiage learning environments? Were these supports effective? Ten key findings clustered in three areas emerged from this study: multilevel classrooms were: 1) beneficial to the teacher when they had students for more than the traditional academic year; multilevel classrooms allowed for the development of independent thinkers and learners; 2) students in the multilevel classroom exhibited positive interactions, nurturance and spirit of cooperation, and 3) team teaching provided an opportunity to learn and share new skills, and provided both pedagogical and affective support for the educators involved. Challenges included: 1) meeting the needs of a more diverse group of learners; 2) piloting change in a culture and climate that was largely against the change and/or did not fully understand the change, and 3) the instance of negative peer role models within the multiage class composition. Foremost, the findings of this study indicated that the participants initially drew from their experience as graded teachers to make sense of the multilevel philosophy, in essence filtering multilevel philosophy through the lens of gradedness. In doing so each participant created a ‘false understanding’ of the multilevel philosophy. It was not until they began employing multilevel strategies within their classrooms and saw the resultant benefits of those strategies that they began to reflect, personally challenge, deconstruct and finally begin to reconstruct their understanding of the multilevel philosophy, and in essence their professional identities.

description: Electronic patient records (EPRs) are replacing paper notes in hospitals across the National Health Service (NHS). Digital records have been promised to provide increased accessibility, legibility, safety, and efficiency, but despite costly national programmes, adoption of EPRs in hospitals, as replacements for paper, has been slow. In addition, research has shown that removal of paper records as a central communication and collaboration device appears to have unintended consequences for the ways that clinicians work together. This project, based in an NHS hospital, used ethnographic methods to observe an EPR in use on paperlight inpatient medical wards. Informed by actor-network theory, this thesis gives an account of how the relocation of information, from paper records to the EPR devices, is changing the ways that medicine is practiced. Through following the use of computers on wheels and handheld digital devices, the findings of this research emphasise the role that the materiality of the medical record has in both the evolution and holding together of clinical practices. These findings form the central contribution of this thesis, which is the development of the concept of the materialised EPR and how the physical housing of the electronic record has effects in collaborative and communicative healthcare settings. The findings emphasise the ways in which mobile digital devices lack the material and tangible properties of paper records, which functioned as a sophisticated network of physical coordination tools in the support of medical practices. This research provides novel insights on the utilisation of medical records, and how their materiality participates in shaping medical practice. This reconfigured work has consequences, not only in the way that communication and collaboration are changing between professionals, but also in influencing care.

description: The pair density wave (PDW) is a novel superconducting state in which Cooper pairs carry center-of-mass momentum in equilibrium, leading to the breaking of translational symmetry. Experimental evidence for such a state exists in high magnetic field and in some materials that feature density wave orders that explicitly break translational symmetry. However, evidence for a zero-field PDW state that exists independent of other spatially ordered states has so far been elusive. Here, we show that such a state exists in the iron pnictide superconductor EuRbFe4As4 (Eu-1144), a material that features coexisting superconductivity (Tc ~ 37K) and magnetism (Tm ~ 15 K). We show from the Spectroscopic Imaging Scanning Tunneling Microscopy (SI-STM) measurements that the superconducting gap at low temperature has long-range, unidirectional spatial modulations with an incommensurate period of ~8 unit cells. Upon raising the temperature above Tm, the modulated superconductor disappears, but a uniform superconducting gap survives to Tc. When an external magnetic field is applied, gap modulations disappear inside the vortex halo. The SI-STM and bulk measurements show the absence of other density wave orders, showing that the PDW state is a primary, zero-field superconducting state in this compound. Both four-fold rotational symmetry and translation symmetry are recovered above Tm, indicating that the PDW is a smectic order.
Making the Sneutrino a Higgs with a $U(1)_R$ Lepton Number

description: We present a supersymmetric extension of the Standard Model that posseses a continuous $ U(1)_R$ symmetry, which is identified with one of three lepton numbers, and where a sneutrino vev gives mass to the down type quark and leptons. This idea allows for a smaller particle content than the minimal $R$-symmetric supersymmetry extension of the standard model (MRSSM). We explore bounds on this model coming from electroweak precision measurements, neutrino masses and gravitino decay. Bounds from electroweak precision measurements lead to a two-sided bound on $\tan β$ while gravitino decay forces a low reheating temperature. Finally, the generation of neutrino masses from $R$-symmetry violation put an upper bound on the SUSY breaking scale. Despite all of this, we find that the allowed parameter space is still large and would lead to a distinctive phenomenology at the LHC.

Women's Attention as a Function of Body Dissatisfaction and Images of Thin Models: An Eye-Tracking Study
Creators: name: Tobin, Leah
Publisher: name: Graduate Studies
Year: 2015
Subjects: subject: Psychology--Clinical
subject: Body Image
subject: Attentional Bias
subject: Thin Media

description: To gain insight into cognitive underpinnings of body dissatisfaction, we compared attentional biases in body-dissatisfied and body-satisfied women, as well as the influence of thin media images on attention. Women (42 body-dissatisfied and 40 body-satisfied) completed a paradigm measuring attention to fat- and thin-related words via eye gaze, both before and after exposure to images of thin models. Participants self-reported on height, weight, and body dissatisfaction. Body-dissatisfied women paid more attention to weight words (both fat and thin) than body-satisfied women. Exposure to thin model images did not affect attention to weight words. Body mass index was related to attention to fat words only prior to image exposure. Our findings suggest that body-dissatisfied women display an attentional bias to weight words but not in the direction predicted by the cognitive model of eating disorders, and that brief exposures to models do not affect the attentional biases.
Publication patterns of award-winning forest scientists and implications for the ERA journal ranking

description: Publication patterns of 79 forest scientists awarded major international forestry prizes during 1990-2010 were compared with the journal classification and ranking promoted as part of the 'Excellence in Research for Australia' (ERA) by the Australian Research Council. The data revealed that these scientists exhibited an elite publication performance during the decade before and two decades following their first major award. An analysis of their 1703 articles in 431 journals revealed substantial differences between the journal choices of these elite scientists and the ERA classification and ranking of journals. Implications from these findings are that additional cross-classifications should be added for many journals, and there should be an adjustment to the ranking of several journals relevant to the ERA Field of Research classified as 0705 Forestry Sciences.

description: Over the past four decades, there has been an increased call for prevention and promotion efforts to address increasing rates of eating disorders and obesity in children (Public Health Agency of Canada [PHAC], 2011a; 2011b). Despite efforts, there are ongoing concerns about weight-related issues in children such as weight dissatisfaction (Davison, Markey, & Birch, 2003); dieting and disordered eating (McVey, Tweed, & Blackmore, 2005); and weight bias, weight-based teasing, and weight-based victimization (Peterson, Puhl, & Luedicke, 2012). Addressing children’s weight-related issues in schools is a very complex endeavour. The purpose of this project was to engage a school community in a collaborative approach to improving body image and diversity acceptance. A feminist-informed participatory action research (f-PAR) approach was used. Piran and Teall’s (2012) Developmental Theory of Embodiment was used to critically examine experiences of embodiment as well as gender, power, and relational issues. However, practical and political challenges occurred during the research process. Conflicting priorities, administrative gatekeeping, silencing, teacher non-engagement, and lack of parental and student knowledge of the research impacted the project. Two teacher in-services, a teacher focus group, and a parent in-service were conducted. The Body Image Kits (Body Image Works, 2005) were used in Junior High health classes, and body image discussions occurred in Senior High Career and Life Management (CALM) classes. Participants identified a number of issues affecting students’ body image. Action initiatives included the development of Elementary and Junior High Girls Groups, changing the school fundraising policy, and revisiting the staff wellness plan. Collaborative discussions with educational policy makers about policies and practices regarding children’s weight-related issues in schools are indicated. There is a need to listen to students’ voices, transform the school context, develop a Comprehensive School Health approach, improve teacher professional development, utilize a social justice perspective, and involve parents. University-school research partnerships are indicated to utilize evidence-based best practices and build capacity. In conclusion, the creation of a healthy school environment involves far more than healthy nutrition plans and physical activities: it requires an orientation towards social justice and the courage to advocate for social change.
