Wolf-Rayet stars
Astronomy

description: Wolf-Rayet (WR) stars are a late stage in the evolution of massive stars (M ≥ 25 M⊙), characterized by strong stellar winds (dM/dt ~ 10−5 M⊙/yr). Ionizing radiation from the central star heats the expanding outer envelope of material, leading to recombination emission lines of helium, carbon, nitrogen, oxygen, and/or hydrogen in the WR star spectrum. This outflow of material enriches the surrounding ISM, which is further enriched when the WR star likely explodes as a type Ib or Ic supernova. WR stars are also likely progenitors for long soft gamma-ray bursts, and they are excellent tracers of the present sites of massive star formation in our Galaxy.
      The current Galactic WR star catalog is very incomplete. I discuss three methods of selecting strong WR star candidates from crowded fields in the Galactic plane: image subtraction, narrowband (NB) color, and broadband (BB) color. Using these methods, an extensive near-infrared narrowband survey begun in 2005-2006, and extended by me, has yielded 28% of the known Galactic WR stars to date; I add 59 new WR stars to the total in this thesis. I then compare two recent models of the Galactic population of WR stars, discuss the implications with respect to how many WR stars remain to be found, and use these results to inform an analysis of the remaining 834 strong carbon-rich WC star candidates from the survey. I also provide a listing of these 834 WC star candidates throughout our Galaxy, and map them; a central result of this thesis. Finally, I present selection criteria which may be used to identify [WR] stars (central stars of planetary nebulae which display WR spectral features), and proof of concept observations which led to 7 new confirmed [WC] stars.

description: Geocrinia Blake 1973
 Geocrinia Blake, 1973. Type species: Pterophrynus laevis Günther, 1864, by original designation.
 Hesperocrinia Wells and Wellington, 1985. Type species: Crinia leai Fletcher, 1898, by original designation. Synonymy by acclamation.
 Definition. Terrestrial/aquatic life history, aquatic exotrophic larvae with keratinised feeding mouthparts, larvae> 20 mm in maximum length, adults <31 mm in maximum length, fourth toe length> 7mm (G. leai / G. victoriana) and> 6mm (G. laevis), testes mass> 0.001 g, egg compliment>50; biphasic call, primarily autumn breeding.
 Content. Three species: Geocinia laevis (Günther), leai (Fletcher), and victoriana (Boulenger).
 Distribution. Occurring in southern Australia (south-eastern and south-western).
 Etymology. The generic name Geocrinia is derived from Ancient Greek, a combination of the prefix γεω- (geô-) “earth” and verb κρῑνω (krînô) “to separate”. While no etymology was provided by Blake, it presumably means “earth Crinia ”, referring to the terrestrial egg deposition and larval development of the contained species relative to the aquatic life history of the morphologically similar Crinia.

description: We develop a theory of soliton spiraling in a bulk nonlinear medium and reveal a new physical mechanism: periodic power exchange via induced coherence, which can lead to stable spiraling and the formation of dynamical two-soliton states. Our theory not only explains earlier observations, but provides a number of predictions which are also verified experimentally. Finally, we show theoretically and experimentally that soliton spiraling can be controled by the degree of mutual initial coherence.

description: Between 1898 and 1913, the limited manpower and resources of the United States Army forced it to employ thousands of Cubans and inhabitants of the Philippines to fight the Spanish and Philippine-American and Moro Wars and conduct civil administration in Cuba and the Philippines. The colonial military labor of Cubans and Philippine islanders both affirmed and challenged the claims of American political and military leaders that the United States practiced a liberal and benevolent form of colonial and neo-colonial rule. In the Pacific Ocean and Caribbean Sea, the U.S. army's exploitation of ordinary colonial subjects breathed new life into often coercive colonial institutions, such as Chinese migrant contract labor, forced labor for public works such as roads, and the impressment of interpreters and guides and other intermediaries for military operations. The impact of American military labor relations in war and occupation endured well into periods of civilian rule in these countries, shaping the politics of race and immigration, infrastructure development and public obligation, and the civil apparatus of colonial and neo-colonial states.

description: Supernovae (SNe) are considered to have a major role in dust enrichment of high redshift galaxies and, due to the short lifetimes of interstellar grains, in dust replenishment of local galaxies. Here we explore how SN dust yields depend on the mass, metallicity, and rotation rate of the progenitor stars, and on the properties of the explosion. To this aim, assuming uniform mixing inside the ejecta, we quantify the dust mass produced by a sample of SN models with progenitor masses $13~M_{\odot} \leq M \leq 120~M_{\odot}$, metallicity $\rm -3 \leq [Fe/H] \leq 0$, rotation rate $\rm v_{\rm rot} = 0$ and $300$~km/s, that explode with a fixed energy of $1.2 \times 10^{51}$~erg (FE models) or with explosion properties calibrated to reproduce the $\rm ^{56}Ni$ - $M$ relation inferred from SN observations (CE models). We find that rotation favours more efficient dust production, particularly for more massive, low metallicity stars, but that metallicity and explosion properties have the largest effects on the dust mass and its composition. In FE models, SNe with $M \leq 20 - 25 ~M_{\odot}$ are more efficient at forming dust: between 0.1 and 1 $M_\odot$ is formed in a single explosion, with a composition dominated by silicates, carbon and magnetite grains when $\rm [Fe/H] = 0$, and by carbon and magnetite grains when $\rm [Fe/H] < 0$. In CE models, the ejecta are massive and metal-rich and dust production is more efficient. The dust mass increases with $M$ and it is dominated by silicates, at all [Fe/H].

description: The complexity of (unbounded-arity) Max-CSPs under structural restrictions is poorly understood. The two most general hypergraph properties known to ensure tractability of Max-CSPs, $β$-acyclicity and bounded (incidence) MIM-width, are incomparable and lead to very different algorithms. We introduce the framework of point decompositions for hypergraphs and use it to derive a new sufficient condition for the tractability of (structurally restricted) Max-CSPs, which generalises both bounded MIM-width and \b{eta}-acyclicity. On the way, we give a new characterisation of bounded MIM-width and discuss other hypergraph properties which are relevant to the complexity of Max-CSPs, such as $β$-hypertreewidth.

The Wounded Educational Leader: A Qualitative Study of How Six Superintendents Describe and Understand a Wounding Experience

description: Leaders are often wounded in practice, most often psychologically. My dissertation is a qualitative three-part interview study that explored how six superintendents describe and understand a wounding experience—defined as a serious conflict, dilemma, or critical event in leadership practice that has a profound impact on the person. This study was built on Maslin-Ostrowski and Ackerman’s (1998, 2000a, 2000b) and Ackerman and Maslin-Ostrowski’s (2001, 2002a) series of research studies. It addressed a gap in educational research by providing insights needed to better understand how six superintendents described, processed, and made meaning of their wounding experience. Additionally, I explored how they learned, healed, or recovered. Two professors with expertise in educational leadership and practice recommended superintendents who self-identify as having been wounded. I purposefully selected participants located in the eastern United States and conducted three in-depth interviews. All six participants described and understood their wounding crisis as follows—it: (a) originated from doing what they referred to as the right thing for students (and other stakeholders); (b) was a “rub” against their “core values”; and (c) was a “blindsiding experience,” which they did not anticipate. All participants (6/6) stated that they believed that wounding happens to most educational leaders and that being wounded felt inevitable when standing by tough leadership decisions that impacted stakeholders. In addition, all participants (6/6) told me that they had rarely—if ever—discussed their wounding experience. I concluded that these superintendents, who expressed that they cared deeply for their students and communities (i.e., their moral purpose), experienced hurtful wounding crises that they framed predominantly as adaptive challenges in which their values were threatened or compromised, and for these participants, the wounding crises were emotional experiences that were—for the most part—often left undiscussed. These findings imply that spaces are needed where wounded leaders can tell their stories in confidence. I recommend creating forums for voicing, processing, responding to, and learning from wounding crises where leaders can express their emotions to determine avenues for recovery and healing. Supports may include social-emotional development, reflective practices, collegial inquiry, mentoring, and coaching.

description: The little q-Jacobi function transform depends on three parameters. An explicit expression as a sum of two very-well-poised 8W7-series is derived for the dual transmutation kernel (a kind of non-symmetric Poisson kernel) relating little q-Jacobi function transforms for different parameter sets. A product formula for the dual transmutation kernel is obtained. For the inverse transform the transmutation kernel is given as a 3\phi2-series, and a product formula as a finite sum is derived. The transmutation kernel gives rise to intertwining operators for the second order hypergeometric q-difference operator, which generalise the intertwining operators arising from a Darboux factorisation.

Multi-set matrix product state calculations reveal mobile Franck-Condon excitations under strong Holstein-type coupling

description: We show that the dynamics of (vertical) Franck-Condon excitations in the regime where Holstein-coupled vibrational modes mix strongly with electronic degrees of freedom sharply contrasts with the known self-localized behavior of vibrationally relaxed excitations. Instead, the strongly-coupled modes are found to periodically induce resonances between interacting electronic sites, during which effective excitation transfer occurs, allowing Franck-Condon excitations to attain substantial mean square displacements under conditions where relaxed excitations are essentially trapped to a single site. In demonstrating this behavior, we employ a multi-set matrix product state formalism. We find this numerically exact technique to be a remarkably efficient approach to the notoriously difficult problem posed by the Holstein model in the regime where the electronic coupling, the vibrational quantum, and the vibrational reorganization energy are comparable in magnitude.

description: A numerical approach for solving evolutionary partial differential equations in two and three space dimensions on block-based adaptive grids is presented. The numerical discretization is based on high-order, central finite-differences and explicit time integration. Grid refinement and coarsening are triggered by multiresolution analysis, i.e. thresholding of wavelet coefficients, which allow controlling the precision of the adaptive approximation of the solution with respect to uniform grid computations. The implementation of the scheme is fully parallel using MPI with a hybrid data structure. Load balancing relies on space filling curves techniques. Validation tests for 2D advection equations allow to assess the precision and performance of the developed code. Computations of the compressible Navier-Stokes equations for a temporally developing 2D mixing layer illustrate the properties of the code for nonlinear multi-scale problems. The code is open source.

description: Numerical evidence for a finite-time singularity in ideal 3D magnetohydrodynamics (MHD) is presented. The simulations start from two interlocking magnetic flux rings with no initial velocity. The magnetic curvature force causes the flux rings to shrink until they come into contact. This produces a current sheet between them. In the ideal compressible calculations, the evidence for a singularity in a finite time $t_c$ is that the peak current density behaves like $|J|_\infty \sim 1/(t_c-t)$ for a range of sound speeds (or plasma betas). For the incompressible calculations consistency with the compressible calculations is noted and evidence is presented that there is convergence to a self-similar state. In the resistive reconnection calculations the magnetic helicity is nearly conserved and energy is dissipated.

We then analyze the question of the generality of inflationary solutions in this more general setting of a dissipative system. We find a surprisingly rich behavior for the solutions of the dynamical system of equations in the presence of dissipational effects. We also determine that a value of dissipation as small as $\sim 10^{-7} H$ can lead to a smooth exit from inflation to radiation.

description: X-ray binaries with black hole (BH) accretors and massive star donors at short orbital periods of a few days can evolve into close binary BH systems (BBH) that merge within the Hubble time through stable mass transfer evolution. From observational point of view, upon the Roche-lobe overflow, such systems will most likely appear as ultra-luminous X-ray sources (ULXs). To study this connection, we compute the mass transfer phase in systems with BH accretors and massive star donors ($M > 15 \,M_\odot$) at various orbital separations and metallicities using the MESA stellar evolution code. In the case of core-hydrogen and core-helium burning donors (cases A and C of mass transfer) we find the typical duration of super-Eddington mass transfer of up to $10^6$ and $10^5 \, \rm yr$ , with rates of $10^{-6}$ and $10^{-5} \,M_\odot \, \rm yr^{-1}$ , respectively. Given that roughly $0.5$ ULXs are found per unit of star formation rate ($\,M_\odot \, \rm yr^{-1}$), and assuming that $10\%$ of all the observed ULXs form merging BBH, we estimate the rate of BBH mergers from stable mass transfer evolution to be at most $10 {\rm ~Gpc}^{-3} {\rm ~yr}^{-1}$.

description: We report the discovery of two Li-rich giant stars (fainter than the red giant branch bump) in the stellar system Omega Centauri using GIRAFFE-FLAMES spectra. These two stars have A(Li)=1.65 and 2.40 dex and they belong to the main population of the system ([Fe/H]=--1.70 and --1.82, respectively). The most Li-rich of them (#25664) has [Na/Fe]=+0.87 dex that is ~0.5 dex higher than those measured in the most Na-rich stars of Omega Centauri of similar metallicity. The chemical abundances of Li and Na in #25664 can be qualitatively explained by deep extra mixing efficient within the star during its RGB evolution or by super-asymptotic giant branch (AGB) stars with masses between ~7 and 8 Msun. In the latter scenario, this Li-Na-rich star could be formed from the pure ejecta of super-AGB stars before the dilution with pristine material occurs, or, alternatively, be part of a binary system and experienced mass transfer from the companion when this latter evolved through the super-AGB phase. In both these cases, the chemical composition of this unique object could allow to look for the first time at the chemical composition of the gas processed in the interior of super-AGB stars.

description: The purpose of this qualitative teacher research study is to explore the ways in which the use of performance in the college composition classroom can impact under-represented writers and their engagement in the writing process. Through the lens of performance theory, this study identifies how students present their sociocultural knowledge through writing and explores how this presentation, as a performance of the self, informs pedagogical practice. One of the major problems typically troubling developmental or basic freshman composition classrooms is that too many of the students seem detached from their own writing and indifferently engaged in their own writing process. This study focuses on examining how the students’ presentation of their knowledge and their own lived experiences through writing and performing their writing in collaboration with classmates influences the quality of their engagement with their own writing and their attitudes toward the academic work of a freshman English class. To this end, data were collected in the form of observation field notes of student writing conferences and performances, student responses to reflective questions, and student writing. The study used discourse analysis to examine, compare, and analyze the data collected. My interpretations of data were framed by my own performance experiences and the discourse of performance theory, which allowed me to analyze my students’ conferences and group work as rehearsals and preparation for the final performance of their writing and their writing as a performance of the self.
The World Could Not Contain the Pages: A Sufi Reading of the Gospel of John Based on the Writings of Muḥyī al-Dīn Ibn al-ʿArabī (1165-1240 CE)

description: This dissertation addresses the question: how might the Sufi master, Muḥyī al-Dīn Ibn al-ʿArabī (1165-1240 CE), have read the Gospel of John? Although the Gospel of John belongs originally to the Christian tradition, this dissertation is a contribution to Islamic Studies, endeavoring to illuminate Ibn al-ʿArabī’s distinctive manner of reading religious texts and to highlight features of his negotiation of a dual heritage from Jesus and Muḥammad. To set Ibn al-ʿArabī’s thought against an Islamic backdrop and situate it in an Islamic context, this dissertation adopts the device of constructing a commentary, guided by seminal passages in Ibn al-ʿArabī’s written corpus, on an Arabic translation of the Gospel of John: the Alexandrian Vulgate, widely circulated in the Arab world during Ibn al-ʿArabī’s time. This amounts not only to a comparison between Johannine doctrines and Ibn al-ʿArabī’s doctrines, but also a comparison between the latter and historical Muslim commentaries on the Christian scriptures—particularly the Biblical commentary (in circulation by the thirteenth century) attributed to the famed Sufi theologian Abū Ḥāmid al-Ghazālī, and the fourteenth-century Muslim Biblical commentary by Najm al-Dīn al-Ṭūfī (d. 1316 CE). Part I of the dissertation establishes a foundation for the commentary, inquiring into Ibn al-ʿArabī’s general attitudes towards non-Islamic religions, then considering autobiographical accounts of his relationship to Christianity, the question of his familiarity with the New Testament, and illustrations of his creative engagement with Christian doctrines. Part II of the dissertation constitutes the commentary, considering Ibn al-ʿArabī’s possible views on a number of Johannine doctrines: Jesus’ claim to have been the son of God; Jesus’ claim to have been one with God; the doctrine that Jesus was the embodied Word; the expiatory and epistemic functions of the embodied Word (paralleled by a dialectic relationship between two divergent kinds of witnessing); and the rumor, at the end of the Gospel of John, that the Beloved Disciple would never die.

description: Mutualistic interactions including pollination are essential for the functioning of ecosystems, but increasingly endangered due to anthropogenic disturbances. Understanding factors that affect their stability is therefore essential.We use a population dynamics model in combination with a trait-based network architecture to investigate the stability and structure of bipartite mutualistic networks.We find that pollinator specialisation increases robustness, i.e. the proportion of surviving species, when survival is limited by pollinator competition, by low interaction strengths, or by high mortality rates. In the opposite situations, networks with more generalists are more robust.When plant-pollinator interactions depend in an asymmetric way on their trait difference, nestedness is increased compared to a model with symmetric interactions, and specialists and generalists show a different distribution in trait space. Increased nestedness is only in some situations correlated with a higher robustness, while in other situations the correlation is negative or neutral.
The Youth in Iceland Model and Icelandic Adolescent Mental Health

description: Over the last 20 years, Iceland has made major progress in reducing substance use among its youth. Many credit this impressive reduction to implementation of the Youth in Iceland (YiI) Model. YiI programming aims to prevent substance use by increasing youth social support through strengthening family relationships, peer relationships, community connection, and community engagement. It involves a wide variety of relevant stakeholders, including policymakers, teachers, parents, and youth workers. Specific programming ranges from recreational sports teams to parental neighborhood watches.
      While studies have indicated that YiI programming has greatly reduced substance use among youth, new data have suggested that mental health problems are rising among Icelandic adolescents. Despite an increase in the prevalence of mental health problems, no studies have explored the impact of YiI programming on Icelandic youth mental health.
      This mixed-methods project consisted of three studies that evaluated the effect of YiI Model programming on Icelandic adolescent mental health. In the first study, a secondary data analysis of cross-sectional YiI Survey data of all 8th to 10th grade students enrolled in Icelandic public schools was performed to explore the relationship between the YiI Model components and self-reported mental illness symptoms. The annual transnational YiI Survey collects data on demographics, behavior, and other social variables. In the second and third studies, focus groups and interviews were conducted with adolescents and key stakeholders to collect feedback on the YiI Model programming and identify barriers and resources for adolescent mental health. For the secondary data analysis of the YiI Survey data, a multivariate logistic regression model was constructed to relate YiI and mental health scores, including terms for covariates that may confound or bias. To supplement the quantitative component, a content analysis of the transcribed focus groups and interviews was performed to elucidate key themes and patterns surrounding Icelandic adolescent mental health and the YiI model.
      Study results suggest that more engagement in the YiI programming may be associated with fewer symptoms of anxiety and depression. Focus group and interview results pointed to a possible fifth YiI Model domain, and highlighted barriers to adolescent mental healthcare.

description: The wavefunction of an incommensurate ground state for a one-dimensional discrete sine-Gordon model -- the Frenkel-Kontorova (FK) model -- at zero temperature is calculated by the quantum Monte Carlo method. It is found that the ground state wavefunction crosses over from an extended state to a localized state when the coupling constant exceeds a certain critical value. So, although the quantum fluctuation has smeared out the breaking of analyticity transition as observed in the classical case, the remnant of this transition is still discernible in the quantum regime.

Known as cold dark matter, this non-luminous source is predicted to constitute 83% of matter and 26% of mass-energy in the universe.  Experiments are currently searching for dark matter via its possible creation in particle colliders, annihilation in high-density regions of the universe, and interactions with Standard Model particles.  So far dark matter has eluded detection so its composition and properties remain a mystery.
      Weakly interacting massive particles (WIMPs) are hypothetical elementary particles that interact on the scale of the weak nuclear force.  They naturally satisfy predictions from extensions of the Standard Model, and are one of the most favored dark matter candidates.  A number of direct detection experiments dedicated to measuring their predicted interactions with atomic nuclei have been constructed over the last 25 years.
      Liquid xenon dual phase time projection chambers (TPCs) have led the field for spin-independent WIMP searches at WIMP masses of >10 GeV/c^2 for most of the last decade.  XENON1T is the first tonne-scale TPC, and with 278.8 days of dark matter data has set the strictest limits on WIMP-nucleon interaction cross sections above WIMP masses of 6 GeV/c^2, with a minimum of 4.1 x10^{-47} cm^2 at 30 GeV/c^2.  XENON1T and the analysis that led to this result are discussed, with an emphasis on electronic and nuclear recoil calibration fits, which help discriminate between background and WIMP-like events.
      Interactions in liquid xenon produce light and charge that are measured in TPCs.  These signals are attenuated by electronegative impurities including O_2 and H_2O, which are homogeneously distributed throughout the liquid xenon.  The decrease in observables enlarges the uncertainty in our analysis, and can decrease our sensitivity.  Methods on measuring the charge loss are presented, and a physics model that describes the behavior of the electronegative impurity concentration over the lifetime of XENON1T is derived.  The model is shown to successfully explain the more than two years of data.

description: We study operator entanglement measures of the unitary evolution operators of (1+1)-dimensional conformal field theories (CFTs), aiming to uncover their scrambling and chaotic behaviors. In particular, we compute the bi-partite and tri-partite mutual information for various configurations of input and output subsystems, and as a function of time. We contrast three different CFTs: the free fermion theory, compactified free boson theory at various radii, and CFTs with holographic dual. We find that the bi-partite mutual information exhibits distinct behaviors for these different CFTs, reflecting the different information scrambling capabilities of these unitary operators; while a quasi-particle picture can describe well the case the free fermion and free boson CFTs, it completely fails for the case of holographic CFTs. Similarly, the tri-partite mutual information also distinguishes the unitary evolution operators of different CFTs. In particular, its late-time behaviors, when the output subsystems are semi-infinite, are quite distinct for these theories. We speculate that for holographic theories the late-time saturation value of the tri-partite mutual information takes the largest possible negative value and saturates the lower bound among quantum field theories.

Binary-Induced Gravitational Collapse: A Trivial Example

description: We present a simple model illustrating how a highly relativistic, compact object which is stable in isolation can be driven dynamically unstable by the tidal field of a binary companion. Our compact object consists of a test-particle in a relativistic orbit about a black hole; the binary companion is a distant point mass. Our example is presented in light of mounting theoretical opposition to the possibility that sufficiently massive, binary neutron stars inspiraling from large distance can collapse to form black holes prior to merger. Our strong-field model suggests that first order post-Newtonian treatments of binaries, and stability analyses of binary equilibria based on orbit-averaged, mean gravitational fields, may not be adequate to rule out this possibility.

Matrix Models in Homogeneous Spaces

description: We investigate non-commutative gauge theories in homogeneous spaces G/H. We construct such theories by adding cubic terms to IIB matrix model which contain the structure constants of G. The isometry of a homogeneous space, G must be a subgroup of SO(10) in our construction. We investigate CP^2=SU(3)/U(2) case in detail which gives rise to 4 dimensional non-commutative gauge theory. We show that non-commutative gauge theory on R^4 can be realized in the large N limit by letting the action approach IIB matrix model in a definite way. We discuss possible relevances of these theories to the large N limit of IIB matrix model.

The Zionist Quest for Honor: France and Jewish Zionist Ideology and Subjectivity

description: This dissertation combines affect, race, history and colonial studies to examine the process of Christian othering of Jews in Europe since the Protestant Reformation, with a focus on the narrative of honor that was used to depict European Jews as lacking it. While the ways Jews were portrayed and constructed have changed as Europe redefined itself through the subsequent centuries, following the Protestant Reformation, this dissertation points out that the essence of Christian perception and depiction of Jews as dishonorable remained unchanged. This study traces how this depiction emerges in French Christian and anti-Semitic representations through a reading of French religious and non-religious texts that have come to gradually produce French Jews, first as a people and then as an ethnic collectivity that does not belong among other nations, all within a narrative of honor. The claim that Jews lack honor came to be internalized subsequently by Zionist Jewish writers and leaders and was spread in Zionist Jewish literature. In providing a history of the constructed social, political, religious and cultural phenomenon of the dishonorable Jew, this dissertation intervenes in the discussions surrounding subjectivity in Zionist thought and how it internalized and adopted the notion of the dishonorable Jew by safeguarding and appropriating Christian and secular Zionist and anti-Semitic sentiments of contempt, disdain, shame and superiority over Diaspora Jews.
Risk and protective factors for bullying in sport: A scoping review

description: The aim of the current study was to examine risk and protective factors related to bullying in sport. Adopting the methodological approach outlined by Arksey and O’Malley (International Journal of Social Research Methodology 8(1):19–32, 2005), 37 articles met the inclusion criteria. A consistent definition of bullying could not be identified in the publications examined, and several articles (n=8) did not explicitly define bullying. The most frequent risk factor identified was an individual’s social background (n=9). Negative influence of coaches (n=5), level of competition (n=5), lack of supportive club culture (n=5) and issues in locker rooms (n=4) were among the most commonly cited risk factors for bullying in sport settings. Preventative policies were cited as the most common method to reduce the incidence of bullying (n=13). Contextually tailored intervention programmes (n=5) were also noted as a key protective factor, particularly for marginalised groups, including athletes with disabilities or members of the LGBTQ+community. The need for sport-specific bullying prevention education was highlighted by 10 of the articles reviewed. In summary, the current review accentuates the range of risk and protective factors associated with sport participation. Furthermore, the need for educational training programmes to support coaches in addressing and preventing bullying within sport settings is emphasised.

description: We present a scheme implementing an a posteriori refinement strategy in the context of a high-order meshless method for problems involving point singularities and fluid-solid interfaces. The generalized moving least squares (GMLS) discretization used in this work has been previously demonstrated to provide high-order compatible discretization of the Stokes and Darcy problems, offering a high-fidelity simulation tool for problems with moving boundaries. The meshless nature of the discretization is particularly attractive for adaptive h-refinement, especially when resolving the near-field aspects of variables and point singularities governing lubrication effects in fluid-structure interactions. We demonstrate that the resulting spatially adaptive GMLS method is able to achieve optimal convergence in the presence of singularities for both the div-grad and Stokes problems. Further, we present a series of simulations for flows of colloid suspensions, in which the refinement strategy efficiently achieved highly accurate solutions, particularly for colloids with complex geometries.

description: We study the sine-Gordon kink diffusion at finite temperature in the overdamped limit. By means of a general perturbative approach, we calculate the first- and second-order (in temperature) contributions to the diffusion coefficient. We compare our analytical predictions with numerical simulations. The good agreement allows us to conclude that, up to temperatures where kink-antikink nucleation processes cannot be neglected, a diffusion constant linear and quadratic in temperature gives a very accurate description of the diffusive motion of the kink. The quadratic temperature dependence is shown to stem from the interaction with the phonons. In addition, we calculate and compute the average value $$ of the wave function as a function of time and show that its width grows with $\sqrt{t}$. We discuss the interpretation of this finding and show that it arises from the dispersion of the kink center positions of individual realizations which all keep their width.

description: Powerful radio sources and quasars emit relativistic jets of plasma and magnetic fields that travel hundreds of kilo-parsecs, ultimately depositing energy into the intra- or inter-cluster medium. In the rest frame of the jet, the energy density of the cosmic microwave background is enhanced by the bulk Lorentz factor squared, and when this exceeds the magnetic energy density the primary loss mechanism of the relativistic electrons is via inverse Compton scattering. The microwave energy density is also enhanced by a factor (1+z)^4, which becomes important at large redshifts. We are using Chandra to survey a z>3 sub-sample of radio sources selected with 21 cm wavelength flux density > 70 mJy, and with a spectroscopic redshift. Out of the first 12 objects observed, there are two clear cases of the X-rays extending beyond the detectable radio jet.
