description: Building on the original work of Bunker and Thorpe and their Teaching Games for Understanding (TGfU) approach to physical education, there is now a proliferation of Game Based Approaches (GBA) in the research literature (Bunker & Thorpe, 1982, A model for the teaching of games in secondary schools. Bulletin of Physical Education, 18, 5–8, 1983). Unlike other approaches to games teaching and coaching which trace their roots to TGfU, Non Linear Pedagogy (NLP) has been defined as distinct from, and even an alternative to, TGfU (Renshaw et al., 2016, Why the constraints-led approach is not teaching games for understanding: A clarification. Physical Education and Sport Pedagogy, 21(5), 459–480. https://doi.org/10.1080/17408989.2015.1095870). Although comparisons between approaches have arisen at a theoretical level, there is no comparison of the influence that these approaches have on learners. Addressing this issue, we turn to Postman and Weingartner’s (1971, Teaching as a subversive activity) pedagogical use of the famous aphorism of Marshall McLuhan, that ‘the medium is the message’. Deploying this concept, we ask: what is the message that the use of these approaches sends? First, we identify the main features of NLP and TGfU. Second, we compare their media with reference to two empirical studies. Third, we identify and discuss questioning and decision-making as two key differences between these otherwise similar approaches. Finally, we consider the implications of these results for teaching and learning of games under Mcluhan’s aphorism.

description: The latest Micromesh Gas Amplification Structures (Micromegas) are achieving outstanding energy resolution for low energy photons, with values as low as 11% FWHM for the 5.9 keV line of $^{55}$Fe in argon/isobutane mixtures at atmospheric pressure. At higher energies (MeV scale), these measurements are more complicated due to the difficulty in confining the events in the chamber, although there is no fundamental reason why resolutions of 1% FWHM or below could not be reached. There is much motivation to demonstrate experimentally this fact in Xe mixtures due to the possible application of Micromegas readouts to the Double Beta Decay search of $^{136}$Xe, or in other experiments needing calorimetry and topology in the same detector. In this paper, we report on systematic measurements of energy resolution with state-of-the-art Micromegas using a 5.5 MeV alpha source in high pressure Ar/isobutane mixtures. Values as low as 1.8% FWHM have been obtained, with possible evidence that better resolutions are achievable. Similar measurements in Xe, of which a preliminary result is also shown here, are under progress.

description: Recently it has been proposed that there are two types of SN Ia progenitors -- short-lived and long-lived. On the basis of this idea, we develope a theory of a unified mechanism for the formation of the bimodal radial distribution of iron and oxygen in the Galactic disc. The underlying cause for the formation of the fine structure of the radial abundance pattern is the influence of spiral arms, specifically, the combined effect of the corotation resonance and turbulent diffusion. From our modelling we conclude that to explain the bimodal radial distributions simultaneously for oxygen and iron and to obtain approximately equal total iron output from different types of supernovae, the mean ejected iron mass per supernova event should be the same as quoted in literature if maximum mass of stars, that eject heavy elements, is $50 M_{\odot}$. For the upper mass limit of $70 M_{\odot}$ the production of iron by a supernova II explosion should be increased by about 1.5 times.

2GP : two-phase graph partitioner
Creators: name: Sinaee, Hadi
Publisher: name: University of British Columbia
Year: 2023

description: Graph partitioning is a crucial problem for processing and analyzing large graphs. The two main classes of graph partitioners are in-memory partitioners and streaming partitioners. In-memory partitioners require that the entire graph be read into memory before being partitioned into some number of partitions. Conversely, a streaming partitioner reads the graph one edge at a time and immediately places the source and destination vertices in a partition, unless they have already been placed. While in-memory partitioners produce higher-quality partitions, they require a large amount of memory and are slow, which makes them less practical for larger graphs. Streaming partitioners can partition large graphs quickly. However, since they lack more information about the overall graph, their placement decisions are not as good as in-memory partitioners, leading to lower-quality partitions. We designed and evaluated a two-phase partitioning algorithm (2GP) that combines the best of both worlds. 2GP has two phases: first, it read a portion of a graph into memory and partitions it using an in-memory partitioner. Then, it partitions the remaining graph using a streaming partitioner. 2GP achieves better partition quality than a state-of-the-art streaming partitioner with significantly better performance.

description: The elecrooptical response of graphene due to heating and drift of carriers is studied theoretically. Real and imaginary parts of the dynamic conductivity tensor are calculated for the case of effective momentum relaxation, when anisotropic contributions are small. We use the quasiequilibrium distribution of electrons and holes, characterized by the effective temperature of carriers and by concentrations, which are controlled by gate voltage and in-plane electric field. The geometry of normal propagation of probe radiation is considered, spectral and field dependences of the reflection coefficient and the relative absorption are analyzed. The ellipticity degree of the reflected and transmitted radiation due to small birefringence of graphene sheet with current have also been determined.

Subjects: linked data, cultural heritage collections, information visualization, coherence techniques, space-time cube, coordinated multiple views

description: Art-historical institutions such as museums and archives are digitizing their object collections, and the same is happening to related art-historical documentation and discourse. Digitized collections allow for new forms of representation and reception, as provided by multiple methods of information visualization. But how can we create more interconnected “bigger pictures” of rich cultural collections? With regard to linked cultural heritage data, we introduce the PolyCubism framework as a means to overcome the imminent risk of putting linked data back into "visualization silos". By utilizing a flexible visualization system of coordinated space-time cubes, a wide variety of relations between entities within the field of art and in other fields of society can become visible.

description: Real world mathematical modeling activities can develop needed and valuable 21st century skills. The knowledge and skills to become adept at mathematical modeling need to develop over time and students in the elementary grades should have experiences with mathematical modeling. For this to occur elementary teachers need to have positive experiences themselves with mathematical modeling. This paper describes how a four-part 21st century skills framework—innovate, synthesize, adapt, and communicate—was integrated with a mathematical modeling activity that one class of pre-service elementary teachers completed. The pre-service elementary teachers were able to generate a variety of ideas, communicate effectively, and work towards successful solutions by using their resources and prior knowledge.

"Bailing with a red SOLO® cup" : recognition, disregard, and the everyday horror of climate crisis in coastal Florida
Creators: name: Jewell, Kendra
Publisher: name: University of British Columbia
Year: 2023

description: By many metrics, the state of Florida is “ground zero” for climate change in continental North America. The reasons for this are manifold: stifling heat, stronger hurricanes, and the swelling ocean combine with ambitious development policies and conservative state leadership that obscure environmental risk in service to capital. In urban centers like Miami, seemingly countless organizations and committees are working to confront the climate crisis head on. Five hours away, in Florida’s whiter, more rural zones, what can seem like extreme environmental risk doesn’t necessarily translate into a fear of – or even a belief in – global climate change. The end result in Florida is a morbidly fascinating cultural-epistemological dissonance, a contradiction in culture and risk perception that’s reaching a fever pitch as the waters rise. In this dissertation, which draws on multi-sited ethnographic fieldwork undertaken in Miami and along Florida’s Gulf Coast, I analyze how the stark realities of environmental shift are felt, integrated, and resisted by people on the front lines of the climate crisis. Specifically, I explore how seemingly different responses to the climate crisis in Florida are steeped in parallel habits of denialism and instincts of environmental mastery that have been ingrained in settler bodies over centuries of brutal domination. I argue that looking away from climate change – whether it’s denied outright or manifests in climate change dissonance – might be thought of as subsumed within a much vaster culture of denial and disregard that finds roots in the horrors of colonialism, slavery, and capitalism more broadly construed. Responsibly mitigating the climate crisis requires reckoning with this culture, lest people and policymakers end up thinking the horrors of climate change are “just part of the thing,” the white noise we all adjust to without even thinking.

description: We study fluctuations in the atom number difference between two halves of a harmonically trapped Bose gas in three dimensions. We solve the problem analytically for non interacting atoms. In the interacting case we find an analytical solution in the Thomas-Fermi and high temperature limit in good agreement with classical field simulations. In the large system size limit, fluctuations in the number difference are maximal for a temperature $T\simeq 0.7 T_c$ where $T_c$ is the critical temperature, independently of the trap anisotropy. The occurrence of this maximum is due to an interference effect between the condensate and the non-condensed field.

A simple example of Value at Risk versus Expected Shortfall in a Generalized Central Limit Theorem World

Publisher: name: Zenodo
Year: 2022
Subjects: heavy-tailed, finance, Expected Shortfall

description: An example of Value at Risk (VaR) versus Expected Shortfall (ES) in a potential heavy-tailed World where the Generalized Central Limit Theorem (GCLT) directly plots daily variations in assets. It consists of a single Python script file with one example and with comments. VaR and ES are calculated for an heavy-tailed Lévy alpha-stable simulation of an example asset as well as for the Gaussian particular case. The insight of footnote 8 of Basel's d457 explanatory document is replicated for both the Gaussian simulation and the heavy-tailed case. This reusable example also highlights how the VaR metric can be deceiving in an heavy-tailed World that only mildly departs from the Gaussian particular case of the GCLT. Percentile calculation in a sample, even if a very large sample (which is used to find the confidence interval to compute VaR), will lead to almost the same value for the Gaussian case as for the case of a Lévy alpha-stable distributed variable with alpha only slightly departing from the Gaussian. However, ES will differ significantly.

A Primer for Mathematical Modeling

Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2013

description: With the implementation of the National Council of Teachers of Mathematics recommendations and the adoption of the Common Core State Standards for Mathematics, modeling has moved to the forefront of K–12 education. Modeling activities not only reinforce purposeful problem-solving skills, they also connect the mathematics students learn in school with the mathematics they will use outside of school. Instructors have found mathematical modeling difficult to teach. To successfully incorporate modeling activities I believe that curricular changes should be accompanied by professional development for curriculum developers, classroom teachers, and higher education professionals. This article serves as an introduction to modeling by defining mathematical modeling, outlining the steps to construct a model, and providing an example that illustrates the iterative non-linear process. Key to teaching modeling is the ability to understand how the modeling process differs from problemsolving activities, which this article discusses. This article describes the benefits and challenges of incorporating mathematical models. The overarching aim of this article is to serve as a primer to aid with the implementation of curricular reforms that call for an increased focus on modeling activities.

description: We study semiparametric varying-coefficient partially linear models when some linear covariates are not observed, but ancillary variables are available. Semiparametric profile least-square based estimation procedures are developed for parametric and nonparametric components after we calibrate the error-prone covariates. Asymptotic properties of the proposed estimators are established. We also propose the profile least-square based ratio test and Wald test to identify significant parametric and nonparametric components. To improve accuracy of the proposed tests for small or moderate sample sizes, a wild bootstrap version is also proposed to calculate the critical values. Intensive simulation experiments are conducted to illustrate the proposed approaches.

description: The most efficient way to pack equally sized spheres isotropically in 3D is known as the random close packed state, which provides a starting point for many approximations in physics and engineering. However, the particle size distribution of a real granular material is never monodisperse. Here we present a simple but accurate approximation for the random close packing density of hard spheres of any size distribution, based upon a mapping onto a one-dimensional problem. To test this theory we performed extensive simulations for mixtures of elastic spheres with hydrodynamic friction. The simulations show a general (but weak) dependence of the final (essentially hard sphere) packing density on fluid viscosity and on particle size, but this can be eliminated by choosing a specific relation between mass and particle size, making the random close packed volume fraction well-defined. Our theory agrees well with the simulations for bidisperse, tridisperse and log-normal distributions, and correctly reproduces the exact limits for large size ratios.

description: This paper discusses an alternative approach for developing problem solving experiences for students. The major argument is that students can develop their creativity by engaging in collaborative problem solving activities in which they apply a variety of mathematical methods creatively to solve problems. The argument is supported by: considering why developing creativity is a worthwhile adventure for students; describing why collaborative problem solving is a unique endeavor in which to engage students more fluidly and less compartmentally; and discussing how students can become skilled at thinking logically and creatively about mathematics content through their engagement in collaborative problem solving tasks.

description: Analyzing the spectra from Wolf-Rayet stars requires adequate non-LTE modeling of their expanding atmosphere. The numerical schemes for solving the radiative transfer in the co-moving frame of reference have been developed by Mihalas and co-workers 30 years ago. The most elaborate codes can cope today with many hundred explicit non-LTE levels or super-levels and account for metal-line blanketing. The limited agreement with observed spectra indicates that the model simplifications are still severe. One approximation that has to be blamed is homogeneity. Stellar-wind clumping on small scales was easily implemented, while "macro-clumping" is still a big challenge. First studies showed that macro-clumping can reduce the strength of predicted P-Cygni line profiles in O-star spectra, and largely affects the X-ray line spectra from stellar winds. The classical model for radiation-driven winds by Castor, Abbot and Klein fails to explain the very dense winds from Wolf-Rayet stars. Only when we solved the detailed non-LTE radiative transfer consistently with the hydrodynamic equations, mass-loss rates above the single-scattering limit have been obtained.

This study therefore analysed the trend of Federal Government agricultural expenditure in Nigeria and ascertained the drivers of agricultural investment outlay using qualitative and quantitative approaches The scope of the study spans 35 years (1981- 2015). Descriptive statistics, pictorial analysis and the co-integration approach were employed The outcome of the study revealed that expenditure patterns fluctuated, rose and become fairly premeditated and consistent with the return of civilian administration, probably due to the priority attention to agriculture and sustained economic management Also, past agriculture expenditures were observed to he long run driver of current agriculture expenditure, thus, affirming the garbage can or instrumentalism approach (probabilistic strategy) to federal government agriculture expenditure in Nigeria, while the outcome on content analysis noted the influences of actors, institutions and ethical state of the country on government agricultural expenditure The study recommended sustenance of democratic tenets, given the expenditure priority focus on agriculture and innovative expenditure programming based on needs and results, rather than random approach to resource allocation and expenditure programming.
The Effects of Constraints in a Mathematics Classroom
Creators: name: Stokes, Patricia D.

description: The dictionary definition of constraint is one-sided, solely restrictive. The problem-solving definition is twosided. Constraints come in pairs. One retains its restrictive function, precluding something specific; the other directs search for its substitute. The paired constraint model is applied to both domain and classroom. I discuss the effects of curricular, variability, testing, cognitive, and talent constraints; demonstrate how paired constraints can be used to create a new curriculum; and close with suggestions for using constraints effectively and creatively in the classroom.

description: In this paper we investigate the von Neumann entropy in the ground state of one-dimensional anyonic systems with the repulsive interaction. Based on the Bethe-ansatz method, the entanglement properties for the arbitrary statistical parameter ($0\leqκ\leq1$) are obtained from the one-particle reduced density matrix in the full interacting regime. It is shown that the entanglement entropy increases with the increase in the interaction strength and statistical parameter. The statistic parameter affects the entanglement properties from two aspects: renormalizing of the effective interaction strength and introducing an additional anyonic phase. We also evaluate the entanglement entropy of hard-core anyons for different statistical parameters in order to clarify solely the effect induced by the anyonic phase.

On the existence of a static black hole on a brane

description: We study a static black hole localized on a brane in the Randall-Sundrum (RS) II braneworld scenario. To solve this problem numerically, we develop a code having the almost 4th-order accuracy. This code derives the highly accurate result for the case where the brane tension is zero, i.e., the spherically symmetric case. However, a nonsystematic error is detected in the cases where the brane tension is nonzero. This error is irremovable by any systematic methods such as increasing the resolution, setting the outer boundary at more distant location, or improving the convergence of the numerical relaxation. We discuss the possible origins for the nonsystematic error, and conclude that our result is naturally interpreted as the evidence for the nonexistence of solutions to this setup, although an "approximate" solution exists for sufficiently small brane tension. We discuss the possibility that the black holes produced on a brane may be unstable and lead to two interesting consequences: the event horizon pinch and the brane pinch.

Substitutional Al solute interaction with edge and screw dislocation in Ni: a comparison between atomistic computation and continuum elastic theory

description: Molecular static simulations have been performed to study the interaction between a single dislocation and a substitutional Al solute atom in a pure crystal of Ni. When the Al solute is situated at intermediate distance from the slip plane, we find that both edge and screw dislocations experiment a non-negligible binding energy. We show that for such length scale the description of the elasticity theory can be improved by taking into account the spreading of dislocation cores via the Peierls-Nabarro model.

description: Nanofluidics has emerged recently in the footsteps of microfluidics, following the quest of scale reduction inherent to nanotechnologies. By definition, nanofluidics explores transport phenomena of fluids at the nanometer scales. Why is the nanometer scale specific ? What fluid properties are probed at nanometric scales ? In other words, why 'nanofluidics' deserves its own brand name ? In this critical review, we will explore the vast manifold of length scales emerging for the fluid behavior at the nanoscales, as well as the associated mechanisms and corresponding applications. We will in particular explore the interplay between bulk and interface phenomena. The limit of validity of the continuum approaches will be discussed, as well as the numerous surface induced effects occuring at these scales, from hydrodynamic slippage to the various electro-kinetic phenomena originating from the couplings between hydrodynamics and electrostatics. An enlightening analogy between ion transport in nanochannels and transport in doped semi-conductors will be discussed.

description: Teaching and learning of mathematical modelling has become a key competence within school curricula and educational standards in many countries of the world. The term mathematical modelling, its meaning, and how it can be implemented in mathematics lessons have been intensively discussed during several Conferences of the European Society for Research in Mathematics (CERME), particularly in the last few years. The aim of the article is to show the similarities and the differences in the teaching and learning of mathematical modelling within education in Europe.

Automatically Discovering Hidden Transformation Chaining Constraints

description: Model transformations operate on models conforming to precisely defined metamodels. Consequently, it often seems relatively easy to chain them: the output of a transformation may be given as input to a second one if metamodels match. However, this simple rule has some obvious limitations. For instance, a transformation may only use a subset of a metamodel. Therefore, chaining transformations appropriately requires more information. We present here an approach that automatically discovers more detailed information about actual chaining constraints by statically analyzing transformations. The objective is to provide developers who decide to chain transformations with more data on which to base their choices. This approach has been successfully applied to the case of a library of endogenous transformations. They all have the same source and target metamodel but have some hidden chaining constraints. In such a case, the simple metamodel matching rule given above does not provide any useful information.

Land privatization and formalization as traditional leasehold properties in Ghana : structure, transparency, and efficiency of the tenure model for housing investment and delivery

description: In the 1980s and 1990s, the Bretton Woods Institutions demanded that debt-destressing countries in the Global South introduce free-market systems to improve efficiency and attract investment to key sectors of the economy, including housing. Following this, several countries in sub-Saharan Africa introduced economic reforms, including traditional land tenure privatization and rights formalization in Ghana. This dissertation examined how the formalization of traditional tenure into leasehold works, including how the leasehold model influences housing investments. I interviewed 21 people – chiefs, landlords, and staff of institutions – involved in leasehold administration and development control and surveyed 420 lessees who function as landlords in the city of Kumasi. These interviews and surveys show that the structure and practices of traditional leaseholds do not meet the tenets of lease creation and tenure security, particularly regarding issues of legitimacy, and certainty, and are thus not equitable and secure. Also, the processes that led to the privatization and formalization of rights in stool lands as traditional leasehold properties lacked transparency and public engagement, factors needed to ensure equity and certainty. Consequently, many lessees lack the necessary institutional knowledge [of leasehold tenure for residential and commercial use] and are, thus, unwilling to comply with the terms and provisions of their lease upon expiry. The study also found that the structure of Ghana’s traditional leasehold reflects a tenure trusteeship model that works to benefit the leaders (chiefs) and to the detriment of the community. Further, the traditional leasehold model (requirements) led to increased transaction costs and market inefficiencies, undermining investment in housing improvements and redevelopment. This outcome, the dissertation argues, is not a function of the formalization of traditional tenure into leasehold, which happened with a constitutional amendment in 1992, instead it is the function of insufficient formalization of leasehold tenure and thus underscores the need to approach land tenure reforms in ways that formalize property rights with clear and enforceable titles to assets. Finally, the study makes a series of policy proposals, including a model (famivest 80-20) to secure improved tenure and finance housing [re]development in cities of Ghana and sub-Saharan Africa and, more broadly, the urban world.

description: Rules for the transformation of time parameters in relativistic Langevin equations are derived and discussed. In particular, it is shown that, if a coordinate-time parameterized process approaches the relativistic Juttner-Maxwell distribution, the associated proper-time parameterized process converges to a modified momentum distribution, differing by a factor proportional to the inverse energy.
