title: The structures of protonated and alkali metal cationized nucleobase self-assemblies and base pairs by infrared multiphoton dissociation spectroscopy and computational methods
Creators: name: Cheng, Ruodi
Publisher: name: Memorial University of Newfoundland
Year: 2019

description: Nucleobases are the bricks of nucleic acids such as deoxyribonucleic acid (DNA)/ribonucleic acid (RNA) molecules. In the current research, ionic nucleobase self-assemblies and base pairs were studied using gas-phase ion techniques in either a Fourier transform ion cyclotron resonance (FTICR) or ‘paul-type’ quadrupole ion-trap (QIT) mass spectrometers. Sustained off-resonance irradiation collision-induced dissociation (SORI-CID) and infrared multiphoton dissociation (IRMPD) were used to fragment the target ions. IRMPD spectroscopy was employed to collect spectra by using tunable IR lasers, either an optical parametric oscillator or amplifier (OPO/A) or a free-electron laser (FEL). Density functional theory (DFT) was mainly used to study the structural information, calculate thermodynamic results, and perform IR frequency calculations for isomers. Besides, computed IR intensities were compared to experimental IRMPD spectra to explore their consistency.
 The study of uracil with Ca²⁺ clusters was presented in Chapter 3. There were agreements between the global minima IR spectra and the experimental results. Uracil tetramer, pentamer and hexamer with Ca²⁺ are composed of both tautomerized and canonical uracils, which were not proposed by previous work. Further research on discovering the structures of 1-methylcytosine dimers with alkali metal cations has revealed two possible structures; a new one which is in planar geometry containing the interbase hydrogen bonding as well as being bound by the metal cation (Chapter 4). There was a conclusion that, as alkali metal cations’ radii increased, the ion-dipole interaction weakened. In Chapter 5 the research dug into the effects of alkali metal cations and proton on guanine:cytosine (G:C) base pair. The heavier metal cations were found less likely to interrupt the hydrogen bonds between Watson-Crick G:C base pairs. Moreover, an unexpected great abundance of protonated cytosine for the dissociation of protonated G:C molecule, termed an anomaly by previous works, was explained because of the high proton transfer barrier but not the proposed thermochemistries. Guanine-involved base pair mismatches with protons were discussed in Chapters 6. For (9eG:1mT)H⁺ and (9eG:9eG)H⁺, the lowest energy structures were sufficient to explain their IRMPD spectra while the global minimum of (9eG:9eG)H⁺ presented only one classical hydrogen bond. For (9eG:9mA)H⁺ the lowest energy structures’ weighted-average spectrum was substantially consistent with its IRMPD spectrum.

description: 72. Chrysura trimaculata (Förster, 1853)
Chrysis trimaculata Förster 1853: 307. Syntypes ♀♀; Hungary (ZMB?). Cederberg 2000: 177, Cederberg 2005: 290.
Chrysura trimaculata: Soon 2004: 46, Sörensson 2008b, Dyntaxa 2013.
Distribution. Sweden.—Westpalearctic: southern and central Europe, Asia Minor (Linsenmaier 1997).
Remarks. The species was reported relatively recently from Sweden (Cederberg 2000), as it was found new to the country from Öland (Sörensson 2008b). Currently several localities are known from Öland, and in 2013 it was also recorded from Gotland. C. trimaculata was classified as vulnerable in the Swedish red lists of 2000 and 2005 (Cederberg 2000, 2005), but later it was removed from the list due to the apparently stable population in Öland (Cederberg et al. 2010).

description: We present the first maximum-light ultraviolet (UV) through near-infrared (NIR) Type Ia supernova (SN Ia) spectrum. This spectrum of SN 2011iv was obtained nearly simultaneously by the Hubble Space Telescope at UV/optical wavelengths and the Magellan Baade telescope at NIR wavelengths. These data provide the opportunity to examine the entire maximum-light SN Ia spectral-energy distribution. Since the UV region of a SN Ia spectrum is extremely sensitive to the composition of the outer layers of the explosion, which are transparent at longer wavelengths, this unprecedented spectrum can provide strong constraints on the composition of the SN ejecta, and similarly the SN explosion and progenitor system. SN 2011iv is spectroscopically normal, but has a relatively fast decline (Delta m_15 (B) = 1.69 +/- 0.05 mag). We compare SN 2011iv to other SNe Ia with UV spectra near maximum light and examine trends between UV spectral properties, light-curve shape, and ejecta velocity. We tentatively find that SNe with similar light-curve shapes but different ejecta velocities have similar UV spectra, while those with similar ejecta velocities but different light-curve shapes have very different UV spectra. Through a comparison with explosion models, we find that both a solar-metallicity W7 and a zero-metallicity delayed-detonation model provide a reasonable fit to the spectrum of SN 2011iv from the UV to the NIR.

Critical thinking and Empathy in the Helping Professions

description: As espoused by most institutions of post-secondary education, critical thinking is considered one of the most important outcomes of that education. Despite this, the literature does not provide a coherent or concise meaning for this term. In previous research, examining students’ understandings and discursive uses of critical thinking, empathy was occasionally implicated in a relationship with critical thinking. This research project attempted to further examine students’ understandings of critical thinking and its implicated relationship with empathy through focus groups of graduate students and students pursuing a professional degree in a subset of the helping professions. Using a form of discursive psychology for analysis, three major findings were presented. First, students’ discussions produced a wide array of meanings for critical thinking, but an interpretative repertoire for critical thinking was not made evident. Secondly, students’ talk also demonstrated the rhetorical use of critical thinking to account for what should be occurring in practices of students’ profession or academic disciplines. Finally, students’ discussion of empathy did not evidence an interpretative repertoire for a relationship between critical thinking and empathy. Rather students’ accounts demonstrated considerable discursive flexibility in their talk of critical thinking, which appeared to account for the relationship between critical thinking and empathy found in previous research.

description: We investigate an inhomogeneous Ising model in the context of tax evasion dynamics where different types of agents are parametrized via local temperatures and magnetic fields. In particular, we analyse the impact of backauditing and endogenously determined penalty rates on tax compliance. Both features contribute to a microfoundation of agent-based econophysics models of tax evasion.

Einstein-Hopf drag, Doppler shift of thermal radiation and blackbody friction: A unifying perspective on an intriguing physical effect

description: The thermal friction force acting on an atom moving relative to a thermal photon bath has recently been calculated on the basis of the fluctuation-dissipation theorem. The thermal fluctuations of the electromagnetic field give rise to a drag force on an atom provided one allows for dissipation of the field energy via spontaneous emission. The drag force exists if the atomic polarizability has a nonvanishing imaginary part. Here, we explore alternative derivations. The damping of the motion of a simple harmonic oscillator is described by radiative reaction theory (result of Einstein and Hopf), taking into account the known stochastic fluctuations of the electromagnetic field. Describing the excitations of the atom as an ensemble of damped harmonic oscillators, we identify the previously found expressions as generalizations of the Einstein-Hopf result. In addition, we present a simple explanation for blackbody friction in terms of a Doppler shift of the thermal radiation in the inertial frame of the moving atom: The atom absorbs blue-shifted photons from the front and radiates off energy in all directions, thereby losing energy. The original plus the two alternative derivations provide for additional confirmation of an intriguing physical effect, and leave no doubt regarding its existence.

Learning Chinese : three autobiographical narratives
Creators: name: Lester, Pamela Lyn
Publisher: name: University of British Columbia
Year: 2010

description: This autobiographical case-study is an arts-informed narrative inquiry into learning (Mandarin) Chinese as an Additional Language (CAL). I have been studying Chinese for over a decade, but in this thesis I focus on the six months (September 2009–February 2010) I spent studying CAL at a high intermediate level in Taipei. I offer three creative non-fiction narratives connected to that experience. The first is a language memoir that mixes languages (English and Chinese), poetry and prose. The second is a reader’s theatre script that re- presents conversations on Chinese with a variety of people (students, teachers and expatriates) from my CAL community in Taipei. The third is a bricolage of image-texts related to CAL selected from internet sources. I conceptualize all three narratives as autobiographical in that they explore various sources – individual, communal, and societal – that are invariably woven together in any story of the self. By using multiple autobiographical accounts to explore lived experience I am working with an opportunity to explore the elusive, shifting, context- dependent and influential nature of narrative sense-making. This approach also provides an opportunity for tensions, resolutions, dissonances, and resonances to reverberate across the stories in ways that stimulate unity without the expense of uniformity. Further, each narrative serves to triangulate the others, drawing as they do on different source materials and perspectives. Yet all three narratives are also fundamentally individual creations, identity texts (Cummins, 2006) even, and as such work to investigate how the personal is inevitably professional, the artistic simultaneously academic, and how representation is always also creation. This investigation of narratives and identities is not peripheral to CAL learning itself. As my understanding of the forces operating on my CAL identity increases, implications for my trajectory as a language learner emerge in significant, liberating ways. This in turn, allows the integration of CAL-related linguistic, sociolinguistic, and cultural habits into my ongoing personal narrative to become more conscious, comfortable and complete. I offer this study as an invitation to participate in the important, complex, and urgent work of increasing awareness of one’s self-in-context.

Here, we present an integrated photonic quantum technology platform utilising the silicon-on-insulator material system, where quantum interference and the manipulation of quantum states of light are demonstrated in components orders of magnitude smaller than in previous implementations. Two-photon quantum interference is presented in a multi-mode interference coupler, and manipulation of entanglement is demonstrated in a Mach-Zehnder interferometer, opening the way to an all-silicon photonic quantum technology platform.

description: The effects on the 4f and 5d levels of Ce3+ of its first coordination shell geometry in Ce-doped oxides with a D2 8-fold site, like garnets, are studied with embedded cluster, wave function based ab initio methods. The only deformations of a CeO8 cube that are found to shift the lowest 4f-5d transition to the red are the symmetric Ce-O bond compression and the tetragonal symmetric bond bending. These results are analyzed in terms of centroid and ligand field stabilization energy differences. The splittings of the upper 5d levels and of the 4f levels are also discussed.

Classifying Hyperelliptic Trace Zero Varieties Susceptible To Low Genus Cover Attack

description: A cover attack (on a Jacobian of a curve) is a method of decreasing the complexity of the discrete logarithm problem defined on the Jacobian of a curve by transferring it via a shared cover to the Jacobian of a new curve which admits a more efficient solution for this problem. We study different approaches that have been taken toward cover attacks and we propose new approaches for the problem of finding covers. We then concentrate on the case of cryptosystems based on the Trace Zero Variety (TZV) associated with hyperelliptic curves. We propose and implement an algorithmic solution to answer the question of finding the best cover to attack a given TZV of genus 2 curves. We extend current methods for constructing covers suitable for the attack. Subsequently, we construct all families of covers of genus 3, 4, and 5 which can potentially be used to attack such TZVs. In this way, we classify, as parametric families, all hyperelliptic curves which are vulnerable to a lower genus cover attack. As a result, we develop a method to avoid using hyperelliptic TZVs with a lower genus cover in cryptographic applications.

description: NGC 6240 is a pair of colliding disk galaxies, each with a black hole in its core. We have used laser guide star adaptive optics on the Keck II telescope to obtain high-resolution ($\sim 0.06$") near-infrared integral-field spectra of the region surrounding the supermassive black hole in the south nucleus of this galaxy merger. We use the K-band CO absorption bandheads to trace stellar kinematics. We obtain a spatial resolution of about 20 pc and thus directly resolve the sphere of gravitational influence of the massive black hole. We explore two different methods to measure the black hole mass. Using a Jeans Axisymmetric Multi-Gaussian mass model, we investigate the limit that a relaxed mass distribution produces all of the measured velocity dispersion, and find an upper limit on the black hole mass at $2.0 \pm 0.2 \times 10^9 M_{\sun}$. When assuming the young stars whose spectra we observe remain in a thin disk, we compare Keplerian velocity fields to the measured two-dimensional velocity field measured and fit for a mass profile containing a black hole point mass plus a radially-varying spherical component, which suggests a lower limit for the black hole mass of $8.7 \pm 0.3 \times 10^8 M_{\sun}$. Our measurements of the stellar velocity dispersion place this AGN within the scatter of the $M_{BH}$-$σ_{*}$ relation. As NGC 6240 is a merging system, this may indicate that the relation is preserved during a merger at least until the final coalescence of the two nuclei.

description: While past research has identified the importance of teacher beliefs in informing practice, fewer studies have investigated the context of Canadian French as a Second Language (FSL) teachers in recent years (Lapkin, Mady, & Arnott, 2009; Lawrence, 2014). By considering how practicing FSL teachers in Alberta experience the integration of technology in second language learning, I sought to contribute a current understanding of these influences. Through an interpretive lens, I explored the context of four FSL teachers in an urban school board in southern Alberta. In an instrumental multicase study, qualitative data were collected through semistructured individual interviews, and analyzed using simultaneous thematic coding. The participants’ responses revealed that while current trends in technology integration seem to align well with these teachers’ beliefs, numerous barriers, including the treatment and status of FSL programs in the board, were seen as ongoing challenges in enacting their vision for their professional practice.

En este sentido, la recreación histórica se convierte en un recurso fundamental para aproximar la historia al alumnado y desarrollar en él competencias ciudadanas y de pensamiento histórico, ya que potencia la experiencia directa con los acontecimientos del pasado, en el entorno donde ocurrieron, favoreciendo actitudes de respeto, valoración y conservación del patrimonio en todas sus dimensiones. Conscientes de su valor educativo y partiendo del modelo de recreación histórica que se viene desarrollando en Padules (Almería) desde hace siete años, donde se recrea con el máximo rigor la Paz de las Alpujarras de 1570, proponemos una serie de orientaciones para que el profesorado de educación secundaria pueda emplear la recreación histórica como recurso para estimular en el alumnado un mejor conocimiento e interpretación de los procesos históricos. Señalamos también las posibilidades didácticas de la recreación como eje vertebrador del trabajo interdisciplinar y como motor de aprendizajes significativos, fundamentados en el constructivismo social.

description: Modeling the radiation generated by accreting matter is an important step towards realistic simulations of black hole accretion disks, especially at high accretion rates. To this end, we have recently added radiation transport to the existing general relativistic magnetohydrodynamic code, Cosmos++. However, before attempting to model radiative accretion disks, we have tested the new code using a series of shock tube and Bondi (spherical inflow) problems. The four radiative shock tube tests, first presented by Farris et al. (2008), have known analytic solutions, allowing us to calculate errors and convergence rates for our code. The Bondi problem only has an analytic solution when radiative processes are ignored, but is pertinent because it is closer to the physics we ultimately want to study. In our simulations, we include Thomson scattering and thermal bremsstrahlung in the opacity, focusing exclusively on the super-Eddington regime. Unlike accretion onto bodies with solid surfaces, super-Eddington accretion onto black holes does not produce super-Eddington luminosity. In our examples, despite accreting at up to 300 times the Eddington rate, our measured luminosity is always several orders of magnitude below Eddington.

description: Clearance of apoptotic neutrophils following infection is critical for the resolution of inflammation. Despite demonstrating immunomodulatory properties, the effects of retinoids in neutrophils in the context of an inflammatory response remain unknown. The objective of this project was to evaluate the immunomodulatory properties of retinoic acid (RA) and oxidatively transformed carotene-β (OxC-β) in a model of Mannheimia haemolytica-induced bovine respiratory disease, which is characterized by severe inflammation. Results in vitro and in vivo demonstrate that both RA and OxC-β induce apoptosis in bovine neutrophils and that this phenomenon promotes efferocytosis in bovine macrophages. These effects occur in the absence of antimicrobial properties and any alteration in neutrophil function. The induction of neutrophil apoptosis and their subsequent phagocytic clearance by macrophages are key mechanisms that promote the resolution of inflammation following infection. As such, RA and OxC-β may represent novel nutraceuticals that confer anti-inflammatory benefits following infection.

description: In Canada, both Nexen’s Long Lake and Suncor’s Firebag steam-assisted gravity drainage (SAGD) Projects reported existence of intersecting lean zones that behave as thief zones. Thoroughly understanding the effect of lean zones and improving SAGD operations with such heterogeneity are critically important in reducing the disadvantages of lean zones during SAGD production. The mechanisms of how mobile water affects the SAGD production are thoroughly studied by developing analytical transient solutions. Meanwhile, the effects of the location, thickness, size, and interval distance of lean zones on SAGD are numerically discussed. The relationship between the steam chamber volume and steam-oil ratios is also highlighted. The ten-year history match is performed based on the geological model in the Lone Lake Field. A hybrid cyclic steam stimulation (CSS)/SAGD method is furthermore proposed and studied to overcome the practical problem of low injection pressure due to lean zones.

description: La recreación histórica o historical re-enactment es una actividad recreativa cuyo objetivo es evocar, con el mayor grado de fidelidad posible, la indumentaria y la cultura material de un momento elegido del pasado. Se trata de un fenómeno que ha ido cobrando importancia durante los últimos años y tiene una significativa presencia en producciones audiovisuales, publicaciones divulgativas y aniversarios de efemérides. Los periodos más populares son el Imperio romano (y sus enemigos o aliados), la Era Vikinga, la Baja Edad Media, las Guerras Napoleónicas y la Segunda Guerra Mundial. Este artículo se centra en la evolución de la recreación histórica altomedieval en Europa (siglos V-XI), prestando una especial atención a España. La experiencia parece mostrar que el mejor modo de aumentar el rigor histórico es a través de pequeñas agrupaciones independientes que mantengan vínculos con otras de una misma filosofía.

description: My interdisciplinary art practice, informed by a geological career, is a discourse on the complex inter-relationship of human beings within nature. Interbeing is an installation inspired by a specific event. In June 2013 a catastrophic flood originating in the Canadian Rocky Mountains inundated southern Alberta like an inland tsunami, leaving a swath of destruction along rivers due to erosion, and the deposition of vast cobble beds, a residue of the flood. On a visceral level this experience felt like the end of the world. Through natural cyclical processes the earth is transformed in geological time in contrast to human activity which is transforming the earth on a human timescale. Climate change is impacting the natural earth cycles. Interbeing is located in a natural setting in rural Bragg Creek, Alberta; it is both site specific and universal in its scope. The natural materials, flood stones and forest residue, used for the installation are harvested from the site. “The ambition is not just to translate a local knowledge of place into an artwork that claims to speak universally about nature, but rather to mediate a visceral contact with nature in order to suggest a way of interacting with it.”

description: The viscoelasticity of a two-dimensional liquid strongly-coupled dusty plasma is studied experimentally, without macroscopic shear. Positions and velocities of the dust particles, measured by video microscopy, are used as the inputs to the generalized Green-Kubo relation to obtain the complex viscosity $η(ω)$. The real part of $η(ω)$ (which corresponds to dissipation) diminishes gradually with frequency, while the imaginary part (which corresponds to elasticity) is peaked at a frequency below the 2D dusty plasma frequency. The viscoelastic approximation is found to accurately describe the 2D experimental results for $η(ω)$, yielding the Maxwell relaxation time $τ_M = 0.10 s$. Results for $η(ω)$ are compared to 2D molecular dynamics Yukawa simulations and to a previous experiment that was performed using an oscillating macroscopic shear.

Our approach produces the derived category of the base change scheme $X_L$ if the category one starts with is the bounded derived category of a smooth projective variety $X$ over $K$ and the field extension is finite and Galois. We also investigate how the dimension of a triangulated category behaves under scalar extensions.

description: El Encuentro de Grupos de Recreación Histórica «Peracense siglo XIII» viene desarrollándose, desde el año 2007, en el interior de la fortaleza ubicada en la localidad aragonesa de Peracense. El objetivo de estos encuentros es difundir nuestra historia y, principalmente, nuestro patrimonio de un modo atractivo, pero al mismo tiempo riguroso. Durante estos doce años se ha ido creando una historia, que sirve de telón de fondo, vinculada a los acontecimientos que ocurrían en la corona de Aragón y cómo podían afectar a un castillo de frontera. Pero en esta recreación podemos llegar a realizar una valoración del público, presente en la misma, en las últimas ediciones, a través de la evolución del número de visitantes. ¿Sirven las recreaciones históricas como foco de atracción hacia un elemento patrimonial, como el castillo de Peracense?

description: Deep-water depositional systems are as diverse as their shallow marine counterparts, yet remain more poorly understood. Due to an inability to directly monitor high-energy currents in the deep-sea, key insights about formative processes are deduced from the stratigraphic record. In this thesis, sedimentary processes and stratigraphic architecture of slope depositional systems are studied at multiple scales and in varied datasets. The basis of this investigation are two Cretaceous-aged slope systems of similar relief and evolution: 1) the Brookian succession of the Colville Basin, North Slope, Alaska; and 2) the Tres Pasos-Dorotea succession of the Magallanes Basin, Chile. Sediment transfer from shallow marine shelf settings to the deep-sea is controlled by a variety of allogenic (e.g., sediment supply) and autogenic (e.g., delta lobe switching) factors. 3-D seismic analysis of the Alaskan slope system demonstrates varied sediment delivery beyond the shelf edge to the deep-sea both in time and space. The unique perspective of along-strike variation in slope to basin processes stresses the limitations of classical 2-D interpretations of basin margin evolution (e.g., sequence stratigraphy, trajectory analysis). Lateral switching of shelf-edge delta lobes, for example, variably impacts the shelf-edge trajectory, slope rugosity and linked basin floor sedimentation along strike. In outcropping Chilean strata, a deep-water sediment-routing system segment characterized by the transition from weakly confined to confined channels is identified. This depositional setting has been poorly constrained, and detailed sedimentological analysis characterizes various stratigraphic units attributed to channels, scours, and sandy bedform deposits characterized by back-set stratification. The dataset captures submarine channels in various stages of development, including scour fills and cyclic steps, low aspect-ratio channel fills, and high aspect-ratio channel fills. The outcrop-constrained strata provide the basis for a geocellular model populated with facies and rock properties, which is used to generate a series of synthetic seismic models. Comparison of the lithology model and seismic volumes reveals differences in the expressions of stratigraphic surfaces and sedimentary bodies. Surfaces that are clear in the outcrop are often not imaged in seismic data; conversely, surfaces defined by high amplitude in seismic volumes are often highly composite, comprised of reflections generated from numerous outcrop-constrained surfaces.

Microscopic approach to the proton asymmetry in the non-mesonic weak decay of Lambda-hypernuclei

description: The non--mesonic weak decay of polarized $Λ$-hypernuclei is studied with a microscopic diagrammatic formalism in which one- and two-nucleon induced decay mechanisms, $\vecΛ N \to NN$ and $\vecΛ NN \to NNN$, are considered together with (and on the same ground of) nucleon final state interactions. We adopt a nuclear matter formalism extended to finite nuclei via the local density approximation. Our approach adopts different one-meson-exchange weak transition potentials, while the strong interaction effects are accounted for by a Bonn nucleon-nucleon interaction. We also consider the two-pion-exchange effect in the weak transition potential. Both the two-nucleon induced decay mechanism and the final state interactions reduce the magnitude of the asymmetry. The quantum interference terms considered in the present microscopic approach give rise to an opposite behavior of the asymmetry with increasing energy cuts to that observed in models describing the nucleon final state interactions semi-classically via the intranuclear cascade code. Our results for the asymmetry parameter in $^{12}_Λ$C obtained with different potential models are consistent with the asymmetry measured at KEK.
Liar at First Sight? Early Impressions and Interviewer Judgments, Attributions, and False Perceptions of Faking

description: Recent research and theory suggests interviewer characteristics and early impressions might strongly influence later perceptions and judgments of applicant behaviour. In this study, I experimentally investigated the effects of interviewer personality and first impressions of the applicant on later performance judgments, attributions, and perceptions of applicant faking. The sample comprised 247 undergraduate students. Pre-interview qualifications information about the applicant and applicant impression management during the rapport-building stage were manipulated to determine if early information, before the structured question-and-answer stage of the interview, biased interviewers. Findings demonstrated that early impressions altered interviewers’ perceptions and judgments of the applicant. The same applicant, with lower pre- interview qualifications, was judged a worse performer, and perceived as more deceptive in the same videotaped structured stage of the interview. The applicant was also considered less likeable, competent, and dedicated, and more conceited. Conversely, applicant impression management did not have an effect on interviewer impressions and judgments. Interviewer personality also affected perceptions and attributions of the applicant, where more Machiavellian and lower honesty-humility interviewers perceived more faking and made more negative attributions. Interviewer personality, however, did not relate to judgments of applicant fit and suitability. Based on these findings, human resources practitioners are encouraged to exercise caution with information provided to interviewers pre-interview, and researchers are encouraged to suspect interviewer perceptions of faking as symptomatic of interviewer dispositional and early impression biases.

description: Many researchers have explored the impact or effectiveness of eating disorder and obesity prevention programs in schools. Few, however, have investigated integrated prevention efforts, and despite recommendations to shift the focus to environmental or systemic change, even fewer researchers have considered the broader situation of weight-related issues. In this study, I intend to address this gap by exploring how weight-related issues are negotiated in schools, and what institutional and social practices influence their construction. I used situational analysis to develop a broader picture of the complexities of the situation and the differences or tensions extant. Analysis of multiple sources of data such as research literature, participant interviews, personal memos, and educational curricula/policy documents contributed to a more comprehensive understanding of the elements within the situation. Mapping processes involved in situational analysis indicated multiple tensions involved in promoting health in relation to weight in schools, and highlighted the importance of opening-up conversations amongst various stakeholders involved in the situation. Findings also emphasized the importance of exploring ways to (a) promote acceptance of all bodies, and (b) change policies or practices that contribute to the stigmatization of individuals based on body size.
