Power and Inclusion in Coaching - The Role of Humour
Creators: name: Edwards, Christian
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Sports science and exercise not elsewhere classified

description: Within the field of sports coaching, a burgeoning belief exists that sociological thought has the potential to challenge and shape the boundaries of related knowledge. Such enquiry has set about explaining how coaches manipulate their ‘social competencies’ (Lemert, 1997: x) in order to maintain and improve their various contextual relationships (Jones, 2011a). Despite such developments, a paucity of research still exists examining how humour serves as a vital ingredient in establishing, developing and maintaining social interaction within the coaching context.
The aim of this PhD thesis, therefore, was to explore what type of humour is used, why it was used and the effects of such humour on the context that it occurs. In adopting an interpretive methodology, through ethnographic methods, data were collected by tracking and observing the coaches and players of Senghenyndd City F.C. (pseudonym) during the course of their domestic season. The ‘coding’ of the results moved away from the traditional inductive theorising and used the constant comparative method to revisit existing ideas in respect of the new data collected. The findings were subsequently subject to a ‘light’ theoretical analysis through Goffman’s (1963; 1967; 1983) presentation of self, impression management and interaction order, and Garfinkel’s (1963; 1967) work on social order to highlight how individuals used varying degrees of inclusionary, shared, self-deprecating and disciplinary humour to manage the often micro-political landscape of sports coaching. The results contribute to the recent investigative upsurge into humour and sports coaching by bringing to light the mundane, taken for granted discourses of interaction evident within the relational, everyday aspects coaching.

Duality for Relative Logarithmic de Rham-Witt Sheaves on Semistable Schemes over F_q[[t]]
Creators: name: Zhao, Yigeng
Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2018

description: We study duality theorems for the relative logarithmic de Rham-Witt sheaves on semi-stable schemes $X$ over a local ring $\mathbb{F}_q[[t]]$, where $\mathbb{F}_q$ is a finite field. As an application, we obtain a new filtration on the maximal abelian quotient $\pi^{\text{ab}}_1(U)$ of the \'etale fundamental groups $\pi_1(U)$ of an open subscheme $U \subseteq X$, which gives a measure of ramification along a divisor $D$ with normal crossing and $\text{Supp}(D) \subseteq X-U$. This filtration coincides with the Brylinski-Kato-Matsuda filtration in the relative dimension zero case.

The $L^2$-Torsion Polytope of Amenable Groups
Creators: name: Funke, Florian
Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2018

description: We introduce the notion of groups of polytope class and show that torsion-free amenable groups satisfying the Atiyah Conjecture possess this property. A direct consequence is the homotopy invariance of the $L^2$-torsion polytope among $G$-CW-complexes for these groups. As another application we prove that the $L^2$-torsion polytope of an amenable group vanishes provided that it contains a non-abelian elementary amenable normal subgroup.

description: We prove that in the complement of a highly twisted link, all closed, essential, meridionally incompressible surfaces must have high genus. The genus bound is proportional to the number of crossings per twist region. A similar result holds for surfaces with meridional boundary: such a surface either has large negative Euler characteristic, or is an n-punctured sphere visible in the diagram.

description: In this paper, we consider the Wiener-Hopf algebra, denoted $\mathcal{W}(A,P,G,\alpha)$, associated to an action of a discrete subsemigroup $P$ of a group $G$ on a $C^{*}$-algebra $A$. We show that $\mathcal{W}(A,P,G,\alpha)$ can be represented as a groupoid crossed product. As an application, we show that when $P=\mathbb{F}_{n}^{+}$, the free semigroup on $n$ generators, the $K$-theory of $\mathcal{W}(A,P,G,\alpha)$ and the $K$-theory of $A$ coincides.

Year: 2006
Subjects: subject: 510 Mathematik

description: An asymptotic analysis of a phase field model for solidification in multicomponent alloy systems is presented. In the limit of vanishing interface thickness the related sharp interface model is approximated to second order by taking a non-constant kinetic correction term into account. In numerical experiments the approximation properties of the phase field model as well as the gain in computational effort due to the correction are investigated.
Understanding biomechanical differences in technique between phases of a sprint

description: Sprinting requires the rapid development of velocity while technique changes across multiple steps. Research Themes (Phase analysis, Technique analysis and Induced acceleration analysis) were formulated to investigate and understand the biomechanical differences in technique between the initial acceleration, transition and maximal velocity phases of a sprint.
Theme 1 (Phase analysis) revealed relatively large changes in touchdown variables (e.g. centre of mass height, touchdown distances, shank angles) during the initial acceleration phase. This likely reflects an increasing need to generate larger vertical forces early during stance as a sprint progresses. At toe-off, smaller yet progressive changes in variables (e.g. trunk angles and centre of mass height) across the initial acceleration and transition phases reflect a constraint determining decreases in propulsive forces during a sprint. Theme 2 (Technique analysis) revealed a trend linking smaller horizontal foot velocities and touchdown distances with smaller braking impulses during the transition and maximal velocity phases. Furthermore, moderate to large increases in negative work by the ankle plantar flexors and knee extensors suggests an increased contribution to absorb forces at those joints and maintain the height of the centre of mass as a sprint progresses. Finally, theme 3 (Induced acceleration analysis) revealed that the braking impulses relative to body mass (expressed in m·s-1) due to the accelerations at contact point, which largely resulted from the foot being decelerated at touchdown, increased from -0.01 ± 0.01 m·s-1 to -0.08 ± 0.02 m·s-1 between steps three to 19 of a sprint. The ankle moment provided the largest contributions to centre of mass acceleration throughout stance with the changing orientation of the ground reaction force vector ultimately determined by the increasing foot, shank and trunk angles as the sprint progressed.

This thesis developed the conceptual understanding of the technical differences between different phases of sprinting. It will contribute to the development and evaluation of sprinting technical models associated with different phases of the event and provide a greater understanding of key contributors to performance. As a sprint progresses, sprinters should emphasise the development of the leg mechanics during the terminal swing and early stance phases to ensure step-to-step changes in braking impulses are managed.

description: We present a computer algebra package based on Magma for performing computations in rational Cherednik algebras at arbitrary parameters and in Verma modules for restricted rational Cherednik algebras. Part of this package is a new general Las Vegas algorithm for computing the head and the constituents of a module with simple head in characteristic zero which we develop here theoretically. This algorithm is very successful when applied to Verma modules for restricted rational Cherednik algebras and it allows us to answer several questions posed by Gordon in some specific cases. We could determine the decomposition matrices of the Verma modules, the graded G-module structure of the simple modules, and the Calogero-Moser families of the generic restricted rational Cherednik algebra for around half of the exceptional complex reflection groups. In this way we could also confirm Martino's conjecture for several exceptional complex reflection groups.

description: To examine the validity of the Motor Functional Development Scale for Young Children (DF-mot) to predict motor developmental delays in preterm infants. This retrospective cohort study includes 67 preterm infants who were assessed at 3–5 months by the DF-mot and the Alberta Infant Motor Scale (AIMS); and at 22–25 months by the Bayley Scales of Infant-Toddler Development (Bayley-III). The properties of the DF-mot and the AIMS were examined based on their ability to predict motor delays on the Bayley-III. The DF-mot gross motor subscale −2 SD and the AIMS 10th centile showed best balance between sensitivity and specificity (respectively Se = 57.1%, Sp = 71.7% and Se = 50%, Sp = 73.5%). Overall, the DF-mot fine motor subscale fails to predict motor delays. The DF-mot shows a lack of sensitivity and of positive predictive value to accurately predict motor outcome at 2 years in preterm infants.

description: We give a generalisation of the character formula of Deligne--Lusztig representations from the finite field case to the truncated formal power series case. Motivated by this generalisation, we give a definition of Green functions for these local rings, and prove some basic properties along the lines of the finite field case, like a summation formula. As an application we show that the higher Deligne--Lusztig characters and G\'erardin's characters agree at regular semisimple elements.

Better bitmap performance with Roaring bitmaps

description: Bitmap indexes are commonly used in databases and search engines. By exploiting bit-level parallelism, they can significantly accelerate queries. However, they can use much memory, and thus we might prefer compressed bitmap indexes. Following Oracle's lead, bitmaps are often compressed using run-length encoding (RLE). Building on prior work, we introduce the Roaring compressed bitmap format: it uses packed arrays for compression instead of RLE. We compare it to two high-performance RLE-based bitmap encoding techniques: WAH (Word Aligned Hybrid compression scheme) and Concise (Compressed `n' Composable Integer Set). On synthetic and real data, we find that Roaring bitmaps (1) often compress significantly better (e.g., 2 times) and (2) are faster than the compressed alternatives (up to 900 times faster for intersections). Our results challenge the view that RLE-based bitmap compression is best.

description: Localization of salient facial landmark points, such as eye corners or the tip of the nose, is still considered a challenging computer vision problem despite recent efforts. This is especially evident in unconstrained environments, i.e., in the presence of background clutter and large head pose variations. Most methods that achieve state-of-the-art accuracy are slow, and, thus, have limited applications. We describe a method that can accurately estimate the positions of relevant facial landmarks in real-time even on hardware with limited processing power, such as mobile devices. This is achieved with a sequence of estimators based on ensembles of regression trees. The trees use simple pixel intensity comparisons in their internal nodes and this makes them able to process image regions very fast. We test the developed system on several publicly available datasets and analyse its processing speed on various devices. Experimental results show that our method has practical value.

Freeze-out radii extracted from three-pion cumulants in pp, p-Pb and Pb-Pb collisions at the LHC

description: In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose-Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. In low-multiplicity collisions, unlike in high-multiplicity collisions, two-pion correlations are substantially altered by background correlations, e.g. mini-jets. Such correlations can be suppressed using three-pion cumulant correlations. We present the first measurements of the size of the system at freeze-out extracted from three-pion cumulant correlations in pp, p-Pb and Pb-Pb collisions at the LHC with ALICE. At similar multiplicity, the invariant radii extracted in p-Pb collisions are found to be 5-15% larger than those in pp, while those in Pb-Pb are 35-55% larger than those in p-Pb. Our measurements disfavor models which incorporate substantially stronger collective expansion in p-Pb as compared to pp collisions at similar multiplicity.

description: We calculate the angular dependence of the x-ray linear and circular dichroism at the $L_{2,3}$ edges of $α$-Fe(II) Phthalocyanine (FePc) thin films using a ligand field model with full configuration interaction. We find the best agreement with the experimental spectra for a mixed ground state of $^3E_{g}(a_{1g}^2e_g^3b_{2g}^1)$ and $^3B_{2g}(a_{1g}^1e_g^4b_{2g}^1)$ with the two configurations coupled by the spin-orbit interaction. The $^3E_{g}(b)$ and $^3B_{2g}$ states have an easy axis and plane anisotropies, respectively. Our model accounts for an easy-plane magnetic anisotropy and the measured magnitudes of the in-plane orbital and spin moments. The proximity in energy of the two configurations allows a switching of the magnetic anisotropy from easy plane to easy axis with a small change in the crystal field, as recently observed for FePc adsorbed on an oxidized Cu surface. We also discuss the possibility of a quintet ground state ($^5A_{1g}$ is 250~meV above the ground state) with planar anisotropy by manipulation of the Fe-C bond length by depositing the complex on a substrate that is subjected to a mechanical strain.

description: The guidance system HELIPORT aims to make the components or steps of the entire life cycle of a research project at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) discoverable, accessible, interoperable and reusable according to the FAIR principles. In particular, this data management solution deals with the entire lifecycle of research experiments, starting with the generation of the first digital objects, the workflows carried out and the actual publication of research results. For this purpose, a concept was developed that identifies the different systems involved and their connections. By integrating computational workflows (CWL and others), HELIPORT can automate calculations that work with metadata from different internal systems (application management, Labbook, GitLab, and further). In this poster, the overall system will be presented using a practical example.

description: The phase diagram of a frustrated spin-$S$ zig-zag ladder is studied through different numerical and analytical methods. We show that for arbitrary $S$, there is a family of Hamiltonians for which a fully-dimerized state is an exact ground state, being the Majumdar-Ghosh point a particular member of the family. We show that the system presents a transition between a dimerized phase to a Néel-like phase for $S=1/2$, and spiral phases can appear for large $S$. The phase diagram is characterized by means of a generalization of the usual Mean Field Approximation (MFA). The novelty in the present implementation is to consider the strongest coupled sites as the unit cell. The gap and the excitation spectrum is analyzed through the Random Phase Approximation (RPA). Also, a perturbative treatment to obtain the critical points is discussed. Comparisons of the results with numerical methods like DMRG are also presented.

description: With the increasing popularity of herbomineral preparations in healthcare, a new proprietary herbomineral formulation was formulated with ashwagandha root extract and minerals viz. zinc, magnesium, and selenium. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the herbomineral test formulation using mice splenocytes. The test formulation was divided into two parts. One part was the control without the Biofield Treatment. The other part was labelled the Biofield Treated sample, which received the Biofield Energy Healing Treatment remotely from twenty renowned Biofield Energy Healers. The splenocyte cells were exposed with the test formulation at ranges of 0.00001053 to 10.53 µg/mL for cell viability by MTT assay, with cell viability ranging from 77.50% to 176.52%. TNF-α was significantly inhibited by 15.88%, 15.28%, 12.30%, 12.60%, and 22.72% at 0.00001053, 0.001053, 0.1053, 1.053, and 10.53 µg/mL, respectively in the Biofield Treated test formulation compared to the vehicle control (VC). TNF-α was significantly reduced by 2.33% and 8.35% at 1.053 and 10.53 µg/mL, respectively compared to the untreated test formulation. IL-1β was significantly reduced by 30.81%, 27.36%, 23.92%, 18.40%, 11.27%, and 21.16% at 0.00001053, 0.0001053, 0.001053, 0.01053, 0.1053, and 1.053 µg/mL, respectively in the Biofield Treated test formulation compared to the VC.

description: Several modern control and online identification algorithms for electrical machines are based on fast current slope detection. This paper shows and compares several identification methods for the inverter induced current slopes at high switching frequencies and high bandwidth of the measured signal. Test bench measurements with a SiC-MOSFET-inverter with switching frequencies up to 𝟔𝟎 𝐤𝐇𝐳 and an RL-load are used to compare the different identification methods. Best results among the investigated methods have been achieved with an easy implementable printed circuit board (PCB) design of a planar Rogowski coil.

description: Collective phenomena, whereby agent-agent interactions determine spatial patterns, are ubiquitous in the animal kingdom. On the other hand, movement and space use are also greatly influenced by the interactions between animals and their environment. Despite both types of interaction fundamentally influencing animal behaviour, there has hitherto been no unifying framework for the models proposed in both areas. Here, we construct a general method for inferring population-level spatial patterns from underlying individual movement and interaction processes, a key ingredient in building a statistical mechanics for ecological systems. We show that resource selection functions, as well as several examples of collective motion models, arise as special cases of our framework, thus bringing together resource selection analysis and collective animal behaviour into a single theory. In particular, we focus on combining the various mechanistic models of territorial interactions in the literature with step selection functions, by incorporate interactions into the step selection framework and demonstrating how to derive territorial patterns from the resulting models. We demonstrate the efficacy of our model by application to a population of insectivore birds in the Amazon rainforest.

On the number of connected components of random algebraic hypersurfaces

description: We study the expectation of the number of components $b_0(X)$ of a random algebraic hypersurface $X$ defined by the zero set in projective space $\mathbb{R}P^n$ of a random homogeneous polynomial $f$ of degree $d$. Specifically, we consider "invariant ensembles", that is Gaussian ensembles of polynomials that are invariant under an orthogonal change of variables. The classification due to E. Kostlan shows that specifying an invariant ensemble is equivalent to assigning a weight to each eigenspace of the spherical Laplacian. Fixing $n$, we consider a family of invariant ensembles (choice of eigenspace weights) depending on the degree $d$. Under a rescaling assumption on the eigenspace weights (as $d \rightarrow \infty$), we prove that the order of growth of $\mathbb{E} b_0(X)$ satisfies: $$\mathbb{E} b_{0}(X)=Θ\left(\left[ \mathbb{E} b_0(X\cap \mathbb{R}P^1) \right]^{n} \right). $$ This relates the average number of components of $X$ to the classical problem of M. Kac (1943) on the number of zeros of the random univariate polynomial $f|_{\mathbb{R}P^1}.$ The proof requires an upper bound for $\mathbb{E} b_0(X)$, which we obtain by counting extrema using Random Matrix Theory methods from recent work of the first author, and it also requires a lower bound, which we obtain by a modification of the barrier method. We also provide a quantitative upper bound for the implied constant in the above asymptotic; for the real Fubini-Study model these estimates reveal super-exponential decay of the leading coefficient (in $d$) of $\mathbb{E} b_0(X)$ (as $n \rightarrow \infty$).

description: H-2 is regarded to play a crucial role in the transition from a fossil fuel-based energy economy towards an environmentally friendly one. However, storage of H-2 is still challenging, but palladium (Pd) based materials show exciting properties. Therefore, nanoparticulate Pd has been intensely studied for hydrogen storage in the past years. Here, we stabilize Pd nanoparticles by intercalation between inorganic nanosheets of hectorite (NaHec). Compared to nanoparticles stabilized by the polymer polyvinylpyrrolidone (PVP), the H-2 storage capacity was found to be 86 % higher for identical Pd nanoparticles being intercalated between nanosheets. We attribute this remarkably enhanced H-2 storage capacity to the partial oxidation of Pd, as evidenced by X-ray photoelectron spectroscopy (XPS). The higher amount of holes in the 4d band leads to a higher amount of H-2 that can be absorbed when Pd is stabilized between the nanosheets of hectorite compared to the PVP stabilized nanoparticles.

description: Earlier theory and measurements show that nanomechanical electron shuttles can work as ratchets for radio-frequency rectification, but its performance was hard to predict so far. This paper focuses on the coupled shuttles which can potentially break symmetry better than a single shuttle. We propose a full stochastic model of coupled shuttles, where the mechanical motion of nanopillars and the incoherent electronic tunneling are modeled as a Markov chain. A linear master equation is constructed. In particular, the interaction of the their randomness is taken into account. This model favors analyzing the symmetry breaking that results in the observed rectification current~\cite{Kim2010_PRL}. Further, based on the model we propose the deterministic equations of mean physical variables by assuming multivariate Gaussian distribution, which enables complex device simulation and design.

description: The computational cost of transfer matrix methods for the Potts model is directly related to the problem of \textit{into how many ways can two adjacent blocks of a lattice be connected}. Answering this question leads to the generation of a combinatorial set of lattice configurations. This set defines the \textit{configuration space} of the problem, and the smaller it is, the faster the transfer matrix method can be. The configuration space of generic transfer matrix methods for strip lattices in the Potts model is in the order of the Catalan numbers, leading to an asymptotic cost of $O(4^m)$ with $m$ being the width of the strip. Transfer matrix methods with a smaller configuration space indeed exist but they make assumptions on the temperature, number of spin states, or restrict the topology of the lattice in order to work. In this paper we propose a general and parallel transfer matrix method, based on family trees, that uses a sub-Catalan configuration space of size $O(3^m)$. The improvement is achieved by grouping the original set of Catalan configurations into a forest of family trees, in such a way that the solution to the problem is now computed by just solving the root node of each family. As a result, the algorithm becomes exponentially faster and highly parallel. An additional advantage is that the final matrix ends up being compressed, not only saving space but also making numerical evaluation on $(q,v)$ faster than in a non-compressed scenario. Experimental results for different sizes of strip lattices show that the \textit{Parallel family trees (PFT)} strategy indeed runs exponentially faster than the \textit{Catalan Parallel Method (CPM)}, specially when dealing with dense transfer matrices. We can confirm that a parallel implementation of the PFT algorithm is highly effective and efficient for large problem sizes...
