description: Background: Rural residents have lower levels of physical activity (PA) and higher rates of cancer than non-rural residents. Promoting PA is important for cancer prevention but requires reliable and valid measurement of PA. However, little is known about effectively collecting objective PA data in rural communities. Purpose: We used data from a randomized controlled trial (Heartland Moves), which aims to increase PA in rural Missouri to explore factors associated with successful objective PA data collection and present lessons learned. Methods: Baseline survey and accelerometry data was collected through Heartland Moves (n=368) from August 2019-Februray 2021. Descriptive statistics, chi-squared, and logistic regression analyses were used to explore factors associated with valid wear of objective PA devices. Results: Overall, 77% had valid wear-time. We found associations with valid wear-time for marital status (x(5) = 16.23, p =0.01), living situation (x(2) = 8.13, p = 0.02), meeting self-reported PA guidelines (x(1) = 4.39 p = 0.04), and receiving SMS reminders (x(1) = 22.27, p <0.001). Of recruited participants, 33% were consented for device wear, 69% of whom obtained valid wear-time. On average, participants with invalid wear-time had devices for 36 days, 19 days longer than participants with valid wear-time. Conclusions: Results support three lessons learned (importance of communication, strategies for hard-to-reach groups, and importance of adapting during data collection) for PA data collection in rural communities.

description: We have recently shown that in non-equilibrium spin systems at criticality the limit $\Xin$ of the fluctuation-dissipation ratio X(t,tw) for t >> tw >> 1 can be measured using observables such as magnetization or energy [Phys. Rev.\ E {\bf 68}, 016116 (2003)]. Pleimling argues in a Comment [cond-mat/0309652] on our paper that for such observables correlation and response functions are dominated by one-time quantities dependent only on t, and are therefore not suitable for a determination of $\Xin$. Using standard scaling forms of correlation and response functions, as used by Pleimling, we show that our data do have a genuine two-time dependence and allow X(t,tw) and $\Xin$ to be measured, so that Pleimling's criticisms are easily refuted. We also compare with predictions from renormalization-group calculations, which are consistent with our numerical observation of a fluctuation-dissipation plot for the magnetization that is very close to a straight line. A key point remains that coherent observables make measurements of $\Xin$ easier than the traditionally used incoherent ones, producing fluctuation-dissipation plots whose slope is close to $\Xin$ over a much larger range.

description: Background: There is limited evidence about how social-ecological factors impacting physical activity differ based on rural-urban location or manifest as barriers to physical activity. Purpose: To compare barriers and correlates of physical activity between adults living in rural and urban areas of Canada and to explore interactions between socio-demographic factors and rural-urban location. Methods: We completed a cross-sectional analysis of the 2017 Canadian Community Health Survey Barriers to Physical Activity Rapid Response, with a final weighted sample of 24,499,462 (unweighted n=21,967). Nine barriers were classified as individual motivation-related, individual resource-related, and environmental (social and built). Results: Rural residents had higher odds of reporting barriers to facility access (OR=4.15 [3.58, 4.83]) and lack of social support (OR=1.17 [1.04, 1.32]) compared to urban residents. In the absence of any environmental barriers, rural residents were more likely to meet physical activity guidelines (OR=1.32 [1.10, 1.59]). Social support barriers were associated with lower odds of meeting physical activity guidelines for self-identified females and not males (OR=0.79 [0.66, 0.94]). There was no effect of location on the odds of reporting an individual resource-related variable (e.g., time, energy). Conclusions: Rural and urban residents were equally likely to report individual-level barriers to physical activity, however, rural residents reported increased environmental barriers. It is important to consider place and gender when characterizing barriers to physical activity. Funding: University of Northern British Columbia Research Data Centre.

description: In this paper we study a three dimensional thermocline planetary geostrophic ``horizontal" hyper--diffusion model of the gyre-scale midlatitude ocean. We show the global existence and uniqueness of the weak and strong solutions to this model. Moreover, we establish the existence of a finite dimensional global attractor to this dissipative evolution system. Preliminary computational tests indicate that our hyper--diffusion model does not exhibit any of the nonphysical instabilities near the literal boundary which are observed numerically in other models.

description: This year, for the eleventh time since its inception in the Trade Agreements Act of 1934, the reciprocal trade program is up for Congressional renewal. This program, for which the avowed purpose has been to promote new markets for United States exports by tariff concessions that are carefully chosen so as to cause no injury to protected American interests, will die, with its 1955 extension, on June 30, unless Congress prolongs it by specific legislation.President Eisenhower has made extension of this program a major positive element in his 1958 Administration policy, starting with his State of the Union Message. It has also been the subject of a message to Congress and of legislative proposals, as well as of various press conferences and remarks and of an address to the March bipartisan rally of the National Conference on International Trade. The President's stated reason for the essentiality of the program is the national welfare, and his Cabinet and other Administration officials have followed his lead in a high-powered public effort to induce Congress to enact the desired legislation.

description: Background: Latinx children are disproportionally affected by overweight and obesity. Parents play a central role on children’s development of early healthy behaviors that ultimately impact weight status. To date the majority of available childhood obesity prevention research in the United States (US) among Latinx has focused on Mexican Americans and Mexican immigrants. Central Americans from the northern triangle countries (Guatemala, El Salvador, and Honduras) represent a growing population in the US and there is a lack of research focused on Central American children. Purpose: To assess Central American parents’ perceptions of importance, interest, and preferences (content and delivery) for the development of a home-based intervention designed to promote healthful energy balance-related behaviors (EBRBs) in their preschool-age children. Methods: Cross-sectional survey. Results: Seventy-four Central American parents, majority immigrants (59.5%) and low acculturation level (60.8%) participated. Approximately half were fathers (51.5%), and parents' mean age was 31.6 years. The majority was married (81.1%), low-educational level (

Implementing movement integration in elementary schools through a job-embedded professional development intervention for teachers
Creators: name: Sobolewski, Kristina
name: Kerpan, Serene
Publisher: name: The Health & Fitness Journal of Canada
Year: 2022

description: Background: Movement integration (MI) is a method to increase school-based physical activity (PA). MI helps teachers work towards connecting and meeting diverse education outcomes by infusing PA with a variety of academic subject areas (e.g., math); thus, addressing some time constraint challenges that teachers face increasing children’s PA at school. This approach to integrating PA throughout the school day supports integrative public health aligned physical education, where broad-based PA promotion is designed to extend PA opportunities in schools while supporting diverse education outcomes. Despite documented benefits in PA levels and academic achievement, implementation is low. Purpose: The purpose of this pilot study was to investigate the effects of a job-embedded professional development (JEPD) intervention on teachers’ MI barriers and implementation. An implementation science approach was used to assess the ability of a novel teacher professional development intervention to help close to research to practice gap. Methods: The professional development intervention was developed and delivered through six procedures developed from The Consolidated Framework for Implementation Research and previous MI research. Mixed-methods data was used to develop the intervention and assess outcomes. The intervention was delivered over three weeks to 12 participants. Results: Results indicated a significant increase in teachers self-reported MI use from pre- to post-implementation (Z = -2.138, p = 0.0165, r = 0.6), improved confidence (p = 0.048), and a strong, positive correlation (ꚍƅ = 0.627, p = 0.018) between confidence and competence. Conclusion: JEPD may be an effective strategy to support teachers level behaviour change in implementing MI.

description: Air-sea drag governs the momentum transfer between the atmosphere and the ocean, and remains largely unknown in hurricane winds. We revisit the momentum budget and eddy-covariance methods to estimate the surface drag coefficient in the laboratory. Our drag estimates agree with field measurements in low-to-moderate winds, and previous laboratory measurements in hurricane-force winds. The drag coefficient saturates at $2.6 \times 10^{-3}$ and $U_{10} \approx 25\ m\ s^{-1}$, in agreement with previous laboratory results by Takagaki et al. (2012). During our analysis, we discovered an error in the original source code used by Donelan et al. (2004). We present the corrected data and describe the correction procedure. Although the correction to the data does not change the key finding of drag saturation in strong winds, its magnitude and wind speed threshold are significantly changed. Our findings emphasize the need for an updated and unified drag parameterization based on field and laboratory data.

description: Quantum networks play a major role in long-distance communication, quantum cryptography, clock synchronization, and distributed quantum computing. Generally, these protocols involve many independent sources sharing entanglement among distant parties that, upon measuring their systems, generate correlations across the network. The question of which correlations a given quantum network can give rise to, remains almost uncharted. Here we show that constraints on the observable covariances, previously derived for the classical case, also hold for quantum networks. The network topology yields tests that can be cast as semidefinite programs, thus allowing for the efficient characterization of the correlations in a wide class of quantum networks, as well as systematic derivations of device-independent and experimentally testable witnesses. We obtain such semidefinite tests for fixed measurement settings, as well as parties that independently choose among collections of measurement settings. The applicability of the method is demonstrated for various networks, and compared with previous approaches.

description: MTT Consulting has been tasked with redesigning Chancellor Boulevard between Acadia Road and Drummond Drive. The existing corridor has been assessed and significant issues noted, including: deteriorating road surfaces, a lack of defined bike lanes, vehicles speeding, and traffic congestion near Hamber Road. The preferred design promotes safety and active transportation on the corridor which are in line with the community and client’s goals. The finalized design is defined by the following aspects: ● Multi-modal transportation infrastructure: a two-way bike path and wide pedestrian path on the south side and a multi-use pathway on the north side, ● Four lanes are maintained for vehicle traffic: The roadway has been developed to lower driving speeds including narrowing the lanes and median. ● Pedestrian underpass: Located at Hamber Road near the bus stops and Hamber Elementary School to accommodate the high pedestrian traffic at that intersection and allow for the removal of the existing signal light. The underpass was analyzed and designed in accordance to CSA standards. Synchro analysis software was used for the intersection design, concluding that the intersection of Chancellor Boulevard and Hamber Road will be reconfigured to a protected-T intersection from the existing pedestrian-controlled half signal. Corridor traffic analysis and design was completed in accordance with the Highway Capacity Manual and TAC and AASHTO Standards . Construction is scheduled for May, 2018 with expected completion in August 2018. Based on a Class A cost estimate, the expected total cost for the project will be $4.75 million with an annual maintenance cost of $48,000, including the repair and remediation and preventative maintenance costs.

Decaying neutron propagation in the Galaxy and the Cosmic Ray anisotropy at 1 EeV

description: We study the cosmic ray arrival distribution expected from a source of neutrons in the galactic center at energies around 1 EeV and compare it with the anisotropy detected by AGASA and SUGAR. Besides the point-like signal in the source direction produced by the direct neutrons, an extended signal due to the protons produced in neutron decays is expected. This associated proton signal also leads to an excess in the direction of the spiral arm. For realistic models of the regular and random galactic magnetic fields, the resulting anisotropy as a function of the energy is obtained. We find that for the anisotropy to become sufficiently suppressed below E\sim 10^{17.9}eV, a significant random magnetic field component is required, while on the other hand, this also tends to increase the angular spread of the associated proton signal and to reduce the excess in the spiral arm direction. The source luminosity required in order that the right ascension anisotropy be 4% for the AGASA angular exposure corresponds to a prediction for the point-like flux from direct neutrons compatible with the flux detected by SUGAR. We also analyse the distinguishing features predicted for a large statistics southern observatory.

description: Background: Early childhood educators (ECEs) are important daytime role models for young children; they program and lead physical activity (PA) and sedentary behaviour (SB) opportunities in childcare. Despite this important role, ECEs have noted receiving little PA and SB-related training during their pre-service schooling. Purpose: The purpose of this pilot study was to examine the influence of an e-Learning course in PA and SB on pre- and in-service ECEs’ knowledge, self-efficacy, behavioural intention, and perceived behavioural control. Methods: A pre-post pilot study, part of the larger Training pre-service EArly CHildhood educators (TEACH) study, was conducted with pre-service ECEs recruited from three Canadian colleges, while in-service ECEs were recruited via social media. ECEs completed an online survey via Qualtrics prior to, and immediately following the completion of the e-Learning course (~5 hours). McNemar Chi-Square tests and paired samples t-tests were used to examine changes in ECEs’ question-specific, and total knowledge scores, while Wilcoxon Signed Ranks tests were run to examine changes in self-efficacy, behavioural intention, and perceived behavioural control. Results: A significant increase in both pre- (n = 32) and in-service (n = 121) ECEs’ knowledge from pre- to post-course completion was observed. Additionally, significant positive changes across self-efficacy, behavioural intention, and perceived behavioural control items were displayed by in-service ECEs, while pre-service ECEs exhibited significance for these tools for select items only. Conclusions: These findings offer preliminary evidence of the appropriateness of an e-Learning course for improving ECEs’ knowledge, self-efficacy, behavioural intention, and perceived behavioural control to support physical activity and minimize sedentary time in childcare.

description: (Abridged) We consider the polarization properties of optically thin synchrotron radiation emitted by relativistically moving electron--positron jets carrying large-scale helical magnetic fields. In our model, the jet is cylindrical, and the emitting plasma moves parallel to the jet axis with a characteristic Lorentz factor $Γ$. We draw attention to the strong influence that the bulk relativistic motion of the emitting relativistic particles has on the observed polarization. We conclude that large-scale magnetic fields can explain the salient polarization properties of parsec-scale AGN jets. Since the typical degrees of polarization are $\leq 15%$, the emitting parts of the jets must have comparable rest-frame toroidal and poloidal fields. In this case, most relativistic jets are strongly dominated by the toroidal magnetic field component in the observer's frame, $B_ϕ/B_z \sim Γ$. We also discuss the possibility that relativistic AGN jets may be electromagnetically (Poynting flux) dominated. In this case, dissipation of the toroidal magnetic field (and not fluid shocks) may be responsible for particle acceleration.

description: We compute the error threshold for the semion code, the companion of the Kitaev toric code with the same gauge symmetry group $\mathbb{Z}_2$. The application of statistical mechanical mapping methods is highly discouraged for the semion code, since the code is non-Pauli and non-CSS. Thus, we use machine learning methods, taking advantage of the near-optimal performance of some neural network decoders: multilayer perceptrons and convolutional neural networks (CNNs). We find the values $p_{\text {eff}}=9.5\%$ for uncorrelated bit-flip and phase-flip noise, and $p_{\text {eff}}=10.5\%$ for depolarizing noise. We contrast these values with a similar analysis of the Kitaev toric code on a hexagonal lattice with the same methods. For convolutional neural networks, we use the ResNet architecture, which allows us to implement very deep networks and results in better performance and scalability than the multilayer perceptron approach. We analyze and compare in detail both approaches and provide a clear argument favoring the CNN as the best suited numerical method for the semion code.

description: Background: Early childhood educators (ECEs) play an important role in promoting healthy physical activity (PA) and sedentary behaviour (SB) in childcare, but have reported lacking appropriate training in this area. Purpose: The purpose of this Delphi study was to develop consensus on content to include in a PA and SB e-Learning course for pre-service ECEs. Methods: Two expert panels (PA/SB [n = 26] and ECE [n = 35]) were formed via purposeful sampling of Canadian/international researchers. PA/SB experts were asked to propose topics for the course via online survey. Topics were pooled (n = 19), and in a second survey, both expert panels rated their importance (0 = unimportant to 5 = very important). Mean ratings were ranked by panel, and then pooled to generate an overall ranked list of content areas. Inter-panel agreement of rankings was quantified using Spearman’s rho. Results: Outdoor Play was the top-rated content area (M = 4.77 ± .64), while Monitor PA and Sedentary Time within Your Classroom scored the lowest (M = 3.77 ± 1.44). Content area importance rankings showed moderate-to-strong inter-panel agreement (rs = 0.60, 95% CI: 0.20 to 0.83). Conclusions: Providing pre-service ECEs with PA/SB training is a proactive way to ensure they prioritize healthy PA/SB in childcare. The results of this study provide a solid foundation for the development of this training – and this expert endorsement should facilitate its implementation within ECE programs.

An all-atom model of the peptide is employed and the protein-solvent interactions are approximated by an implicit solvent. Our results demonstrate that generalized-ensemble simulations are well suited to sample low-energy structures of such large polypeptides. Configurations with a root-mean-square deviation (rmsd) to the crystal structure of less than one Åare found. Finally, we discuss limitations of our implicit solvent model.

title: Thermal infrared and optical observations of near-Earth asteroids.

description: Increased physical characterisation of Near-Earth Asteroids (NEAs) is important for understanding their origin and evolution, the links between meteorites and their parent bodies, and for assessing the impact hazard. NEAs are also representative of small main belt asteroids.
Optical observations of 13 NEAs taken at the Jacobus Kapteyn Telescope in 2001 and 2002 are presented, from which composite lightcurves, mean magnitudes, absolute visual magnitudes, rotation periods and lightcurve amplitudes are derived. Thermal infrared photometry and spectrophotometry of 10 NEAs taken at the United Kingdom Infrared Telescope (UKIRT) in March and September 2002 are presented. The Standard Thermal Model (STM), Fast Rotating Model (FRM) and Near-Earth Asteroid Thermal Model (NEATM) have been fitted to the measured fluxes to derive geometric albedos (pv), effective diameters (Deff) and beaming parameters (rj).
The NEATM assumes zero thermal emission on the night side of an asteroid, affecting the best-fit rj, overestimating Deff and underestimating pv at large phase angles. The Night Emission Simulated Thermal Model (NESTM) is introduced. NESTM models the night side temperature (Tnight) as an iso-latitudinal fraction if) of the maximum day side 1/4temperature (Tmax calculated for NEATM with rj = 1): Tnight = fTmax cos (f), where (j) is the latitude. A range of / is found for different thermal parameters, which depend on the surface thermal inertia (T). NESTM is tested on thermal IR fluxes generated from simulated asteroid surfaces with different T. NESTM, NEATM and radar diameters are compared and it is found that NESTM removes a systematic bias of NEATM that overestimates asteroid diameters. From these tests, it is suggested that a version of the NESTM which assumes T = 200 J m-2 s-1/2 K-1 (f~ 0.6) is adopted as a default model when the solar phase angle is greater than 45°.

description: Background: Physical activity (PA) is recommended for children with ADHD to improve symptoms and reduce risk of negative health outcomes. Many studies use subjective report of PA for convenience, but there is limited understanding of how these measures compare to objective measures in children with ADHD. Purpose: To characterize the PA of a sample of children with ADHD who participated in a clinical trial on behavioral parent training and compare parents’ reports of children’s PA to accelerometry. Methods:The sample includes 71 (31 female, mean age 7.9) children with ADHD who met inclusion criteria for the trial (parent-reported <5 days/week of ≥60 mins of MVPA). Children’s PA was assessed by parent report and measured by hip-worn Actigraph accelerometers. Results: Mean MVPA was 52.9 mins/day (via accelerometers), mean days/week with ≥60 mins of MVPA was 2.72 days. 5.6 % of children attained the recommended 7 days/week of ≥60 mins of MVPA. Daily MVPA did not differ by child gender, ADHD medications, or family income. For families with parent-reported PA data (n=59), report of days with ≥60 mins of MVPA (M=2.0 days/week) was different (p=0.018) from accelerometer measures. 51% of parents under-reported days/week with ≥60 mins/day of MVPA compared to accelerometer measure. Conclusions: Children with ADHD in this sample attained suboptimal daily MVPA, but PA was not different by gender, medication use, or family income. On average, parents’ reports underestimated child PA. Funding: Study funded by NIH R21 and R33 Grants for the LEAP Study.

A Figure Painting in Tempera Emulsion

Publisher: name: American University

description: This painting and paper have presented many challenges to me and I feel that in working them out I have learned a considerable amount. Many colleges and universities still abide by the old rules that in order for a painter to obtain a graduate degree he must spend hundreds of hours away from his painting rewriting what others have written about art history, I heartily endorse the new painting thesis program of American University and hope that this system will be continued. The greatest source material for this work was found in galleries rather than books. The original paintings in the National Gallery, the Phillips Collection, and the Corcoran Gallery were of great service to me. I wish to express my appreciation to Miss Sarah Baker, Mr. Robert F. Gates, and Mr. Ben L. Summerford for their interest in my development as a creative painter, and for their assistance with this project.

description: This is the 4-th paper in the series devoted to a systematic study of the problem of mathematically correct formulation of the rules needed to manage an effective field theory. Here we consider the problem of constructing the full set of essential parameters in the case of the most general effective scattering theory containing no massless particles with spin J > 1/2. We perform the detailed classification of combinations of the Hamiltonian coupling constants and select those which appear in the expressions for renormalized S-matrix elements at a given loop order.

title: Parenting capacity and reading with children: enhancing the assessment framework for children in need and their families.
Creators: name: Seden, Pauline Janet
Publisher: name: The Open University
Year: 2006

description: This thesis draws together two strands of thinking to consider their usefulness, when combined, to vulnerable children, their parents and practitioners who work in children's services. One strand conceptualises the abilities and qualities required by a parent to respond to children's developmental needs, as summarised by the term 'parenting capacity', in the psychological and social work literature which underpins assessment and intervention frameworks for practitioners. The second strand is the psychological and educational literature which considers the contribution of reading children's books to child development and the benefits to child-parent relationships of reading together.

Both literatures draw from common knowledge, informed from research into the developmental needs of children and the abilities parents need to raise them. There is also contemporary research and scholarship which interprets the relevance of this heritage in contemporary cultural contexts. To add to and link these understandings, this study explores and discusses the views of 33 contemporary parents. Their views on both what makes for a good parent and the benefits of reading with children were gathered.

The parents' views were analysed within the paradigm of the parenting capacity dimensions of The Framework for the Assessment of Children in Need and their Families, published as government guidance to practitioners in 2000 (Department of Health et al. 2000), which remains relevant to children's services in 2006. The use of this framework which draws mainly from one of the strands of literature that is explored (psychological and social work) means that the second strand of thinking (psychological and education) can be brought into the framework and relevant connections and comparisons made, in order to enhance the understanding of parenting capacity contained there. The study concludes by considering how the findings from this analysis have relevance to child welfare practice in contemporary contexts.

description: Calculating the yield limit $Y_c$ (the critical ratio of the yield stress to the driving stress), of a viscoplastic fluid flow is a challenging problem, often needing iteration in the rheological parameters to approach this limit, as well as accurate computations that account properly for the yield stress and potentially adaptive meshing. For particle settling flows, in recent years calculating $Y_c$ has been accomplished analytically for many antiplane shear flow configurations and also computationally for many geometries, under either two dimensional (2D) or axisymmetric flow restrictions. Here we approach the problem of 3D particle settling and how to compute the yield limit directly, i.e. without iteratively changing the rheology to approach the yield limit. The presented approach develops tools from optimization theory, taking advantage of the fact that $Y_c$ is defined via a minimization problem. We recast this minimization in terms of primal and dual variational problems, develop the necessary theory and finally implement a basic but workable algorithm. We benchmark results against accurate axisymmetric flow computations for cylinders and ellipsoids, computed using adaptive meshing. We also make comparisons of accuracy in calculating $Y_c$ on comparable fixed meshes. This demonstrates the feasibility and benefits of directly computing $Y_c$ in multiple dimensions. Lastly, we present some sample computations for complex 3D particle shapes.
