description: Anticipatory looking on mindreading tasks can indicate our expectation of an agent's action. The challenge is that social situations are often more complex, involving instances where we need to track an agent's false belief to successfully identify the outcome to which an action is directed. If motor processes can guide how action goals are understood, it is conceivable-where that kind of goal ascription occurs in false-belief tasks-for motor representations to account for someone's belief-like state. Testing adults (N = 42) in a real-time interactive helping scenario, we discovered that participants' early mediolateral motor activity (leftwards-rightwards leaning on balance board) foreshadowed the agent's belief-based action preparation. These results suggest fast belief-tracking can modulate motor representations generated in the course of one's interaction with an agent. While adults' leaning, and anticipatory looking, revealed the contribution of fast false-belief tracking, participants did not correct the agent's mistake in their final helping action. These discoveries suggest that adults may not necessarily use another's belief during overt social interaction or find reflecting on another's belief as being normatively relevant to one's own choice of action. Our interactive task design offers a promising way to investigate how motor and mindreading processes may be variously integrated.

description: Die Methode der Positronenannihilationslebensdauerspektroskopie (PALS) wurde zur Charakterisierung einer Reihe von Controlled Pore Glasses (CPG) genutzt. Die im Lebensdauerspektrum zu findende längste Lebensdauer hat ihren Ursprung in der pick-off Annihilation, des in den Mikro- bzw. Mesoporen lokalisierten ortho-Positroniums (o-Ps). Unter Verwendung eines geeigneten Modells lässt sich die gemessene Lebensdauer direkt in eine Porengröße umrechnen. Es wird gezeigt, daß das erweiterte Tao-Eldrup-Modell in Zylindergeometrie eine sehr gute Übereinstimmung von Experimenten an Proben bekannter Porengröße liefert. Die Lebensdauerspektren wurden ebenfalls hinsichtlich der Verteilung der pick-off Lebensdauer untersucht. Es wird eine Methode vorgestellt um aus den erhaltenen Daten direkt eine Porengrößenverteilung zu berechnen. Die erarbeiteten Methoden werden letztlich zur Charakterisierung verschiedener mikro- und mesoporöser Gläser verwendet. Ferner werden erste Messungen zur Phasenumwandlung von verschiedenen Gasen in "confinement" präsentiert.
description: Positron annihilation lifetime spectroscopy (PALS) is used to study a series of controlled pore glasses (CPG). The largest lifetime in the spectrum is attributed to the pick-off annihilation of ortho-positronium (o-Ps) localized at meso- and micropores. The pick-off lifetime is a function of the pore size which can be calculated from the lifetime using an adequate model. It is shown that the Tao-Eldrup model extended to cylinders of infinite length describes well the experiments done on samples with known pore sizes. The spectra were also analyzed allowing a distribution of o-Ps lifetimes. A method is developed to calculate the pore size distribution from the lifetime distribution. The developed methods are used to characterize different porous materials. Furthermore first PALS measurements on the phase transition of different gases in confinement are shown.

description: We introduce the spinor representations for osp(m|2n). These generalize the spinors for so(m) and the symplectic spinors for sp(2n) and correspond to representations of the supergroup with supergroup pair (Spin(m) x Mp(2n),osp(m|2n)). We prove that these spinor spaces are uniquely characterized as the completely pointed osp(m|2n)-modules. Then the tensor product of this representation with irreducible finite dimensional osp(m|2n)-modules is studied. Therefore we derive a criterion for complete reducibility of tensor product representations. We calculate the decomposition into irreducible osp(m|2n)-representations of the tensor product of the super spinor space with an extensive class of such representations and also obtain cases where the tensor product is not completely reducible.
Physical activity measurement strategies in advanced chronic lung disease
Creators: name: Dhillon, Satvir Singh
Publisher: name: University of British Columbia
Year: 2014

description: Background: Physical activity may reduce mortality risk in advanced chronic lung disease by optimizing functional capacity, which is a major prognostic indicator in lung transplantation candidates. There is uncertainty as to the optimal method to measure physical activity in this patient population. We assessed different commercially-available physical activity measurement techniques (flex heart rate monitoring (FHR); pedometry; tri-axial accelerometry; and multi-sensor technology) by investigating their agreement with indirect calorimetry (IC) in adult lung disease patients (chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), and cystic fibrosis (CF)) with advanced pulmonary impairment. Methods: This is a cross-sectional method comparison study conducted on two separate days. We recruited consecutive COPD, ILD, and CF patients with physician diagnosis of advanced pulmonary impairment. On day one, participants performed cardiopulmonary exercise testing until exhaustion with measurements of oxygen uptake (VO₂) and heart rate (HR) collected. On day two, subjects had their VO₂ and HR measured during standardized resting and sub-maximal activity. Simultaneous VO₂ and HR measures from both days were used to develop individual regressions for FHR-derived energy expenditure (EE). We then simultaneously measured each subject’s EE using a variety of index measures of physical activity and IC during standardized “free-living” type activities and varying intensities of sub-maximal cycle exercise. Results: In a sample of eight participants (CF, n=5; COPD, n=2; ILD, n=1), Flex HR methods using submaximal (FMSUB) and CPET-derived (FMCPX) calibrations showed the best agreement and interchangeability with IC during free-living and cycling activities compared to the SenseWear (SW) and ActiCal (AC) devices as evidenced by lower mean differences with IC and widths of limit of agreement (LOA) + 95% confidence interval (CI). For the secondary index methods assessed, the Tractivity and DigiWalker devices significantly over and underestimated IC EE respectively (p<0.05), whereas the Dynaport device did not differ from IC (p>0.05) over the entire protocol. Conclusion: Our study found that the Flex HR method for EE estimation had the lowest bias and variability during free-living activities and exercise. EE estimation using Flex HR methods may be potentially useful clinical tools to ensure metabolic energy balance and activity monitoring in advanced lung disease groups.

description: We examine sparse grid quadrature on weighted tensor products (WTP) of reproducing kernel Hilbert spaces on products of the unit sphere, in the case of worst case quadrature error for rules with arbitrary quadrature weights. We describe a dimension adaptive quadrature algorithm based on an algorithm of Hegland (2003), and also formulate a version of Wasilkowski and Wozniakowski's WTP algorithm (1999), here called the WW algorithm. We prove that the dimension adaptive algorithm is optimal in the sense of Dantzig (1957) and therefore no greater in cost than the WW algorithm. Both algorithms therefore have the optimal asymptotic rate of convergence given by Theorem 3 of Wasilkowski and Wozniakowski (1999). A numerical example shows that, even though the asymptotic convergence rate is optimal, if the dimension weights decay slowly enough, and the dimensionality of the problem is large enough, the initial convergence of the dimension adaptive algorithm can be slow.

description: In a recent work on Euler-type formulae for even Dirichlet beta values, i.e. $β{(2n)}$, I have derived an exact closed-form expression for a class of zeta series. From this result, I have conjectured closed-form summations for two families of zeta series. Here in this work, I begin by using a known formula by Wilton to prove those conjectures. As example of applications, some special cases are explored, yielding rapidly converging series representations for the Apéry constant, $ζ(3)$, and the Catalan constant, $G = β(2)$. Interestingly, our series for $\,ζ(3)\,$ converges faster than that used by Apéry in his irrationality proof (1978). Also, our series for $\,G\,$ converges faster than a celebrated one discovered by Ramanujan (1915). At last, I present a simpler, more direct proof for a recent theorem by Katsurada which generalizes the above results.

Subjects: subject: 615

description: Im Rahmen dieser Arbeit wurden 79 Naturstoffe aus Pflanzen, Pilzen und Flechten hinsichtlich evtl. Einflüsse auf die Thrombozytenfunktion untersucht. Es stellte sich heraus, dass nur einer dieser Naturstoffe, das Purpurogallin, eine signifikante Hemmung der Aggregation nach Stimulation mit Thrombin auslösen kann. Weiteres Interesse galt dem Permethylpurpurogallin, der methylierten Form des Purpurogallins. Es zeigte sich, dass keine der nachgewiesenen Wirkungen des Purpruogallins auf das Permethylpurpurogallin übertragen werden kann. Der erstmalige Nachweis der Polo-Like-Kinase 1 ist im Rahmen dieser Arbeit gelungen. Ebenfalls konnte nachgewiesen werden, dass die PLK-1 in Thrombozyten in phosphorylierter Form vorliegt. Da ein Zusammenhang zwischen der PLK-1 und den MAPKinasen im Rahmen des Primings der PLK-1 beschrieben wird, haben wir auch untersucht, ob sich die Aktivität der MAPKinasen durch Purpurogallin hemmen lässt. Es konnte nachgewiesen werden, dass Purpurogallin einen hemmenden Einfluß auf die Aktivität auf die MAPKinasen ERK und p38 in Thrombozyten hat.
description: Within the scope of this work, 79 natural products from plants, mushrooms and lichens were examined with regard to possible effects on the platelet function. It turned out, only the purpurogallin, can trigger a significant inhibition of aggregation after stimulation with thrombin. Another drug was the permethylpurpurogallin, the methylated form of purpurogallin. It was shown that none of the detected effects of purpruogallin can be transferred to the permethylpurpurogallin. The first-time detection of polo-like kinase 1 has been successful in this work. It has also been shown that PLK-1 is present in platelets in phosphorylated form. As a link between the PLK-1 and the MAPKinases is described in the context of the priming of PLK-1, we also investigated whether the activity of the MAPKinases can be inhibited by purpurogallin. Purpurogallin has been shown to have an inhibitory effect on the activity on MAPKinases ERK and p38 in platelets.

description: Die Charakterisierung genetischer Variationen in Estrogenrezeptor-α-Koregulatoren kann zu einem besseren Verständnis führen, wie der genetische Hintergrund einer Person die Entstehung von estrogenabhängigen Krankheiten und deren Behandlungschancen beeinflusst. Dies kann zu individuellen Behandlungsmöglichkeiten für Patienten und dadurch zur Verbesserung von Therapien und der Diagnostik in der Zukunft führen. Wir identifizierten einen Einzelnukleotidpolymorphismus im Steroidrezeptor-Koaktivator 1 (SRC-1), der die Aminosäuresequenz von Prolin zu Serin an Position 1272 ändert (SRC-1 P1272S). Dieser Einzelnukleotidpolymorphismus verringert das Koaktivierungspotenzial von SRC-1 und resultiert in verringerter Estrogenrezeptoraktivität, vermutlich durch eine geringere Proteinhalbwertzeit. In vitro und in vivo Daten zeigen eine verminderte Wirkung von endogenem und exogenem Estrogen im Knochen wenn dieser Einzelnukleotidpolymorphismus vorliegt. Klinische Daten zeigten eine verringerte Tamoxifenwirkung bezüglich des Prozesses des Knochenwiederaufbaus. Zusammenfassend zeigen diese Daten, dass Frauen, die diesen Einzelnukleotidpolymorphismus im Genom tragen, einem erhöhten Osteoporoserisiko unterliegen könnten. Ein Screening für SRC-1 P1272S könnte den Therapieerfolg von Tamoxifen zur Verhinderung von Osteoporose beeinflussen. Falls dieser Einzelnukleotidpolymorphismus vorliegen sollte, würde das bedeuten, dass die betroffenen Patienten zusätzliche Therapien benötigen, um den estrogenabhängigen Knochenabbau zu verhindern. Dies ist ein wichtiger Schritt, um individuelle Therapien für die estrogenabhängige Osteoporose zu etablieren.
Bootstrap percolation on the Hamming torus

description: The Hamming torus of dimension $d$ is the graph with vertices $\{1,\dots,n\}^d$ and an edge between any two vertices that differ in a single coordinate. Bootstrap percolation with threshold $θ$ starts with a random set of open vertices, to which every vertex belongs independently with probability $p$, and at each time step the open set grows by adjoining every vertex with at least $θ$ open neighbors. We assume that $n$ is large and that $p$ scales as $n^{-α}$ for some $α>1$, and study the probability that an $i$-dimensional subgraph ever becomes open. For large $θ$, we prove that the critical exponent $α$ is about $1+d/θ$ for $i=1$, and about $1+2/θ+Θ(θ^{-3/2})$ for $i\ge2$. Our small $θ$ results are mostly limited to $d=3$, where we identify the critical $α$ in many cases and, when $θ=3$, compute exactly the critical probability that the entire graph is eventually open.

description: A tree is called double starlike if it has exactly two vertices of degree greater than two.

description: We prove a limit theorem for an integral functional of a Markov process. The Markovian dynamics is characterized by a linear Boltzmann equation modeling a one-dimensional test particle of mass $λ^{-1}\gg 1$ in an external periodic potential and undergoing collisions with a background gas of particles with mass one. The object of our limit theorem is the time integral of the force exerted on the test particle by the potential, and we consider this quantity in the limit that $λ$ tends to zero for time intervals on the scale $λ^{-1}$. Under appropriate rescaling, the total drift in momentum generated by the potential converges to a Brownian motion time-changed by the local time at zero of an Ornstein-Uhlenbeck process.

description: The problem of sharing entanglement over large distances is crucial for implementations of quantum cryptography. A possible scheme for long-distance entanglement sharing and quantum communication exploits networks whose nodes share Einstein-Podolsky-Rosen (EPR) pairs. In Perseguers et al. [Phys. Rev. A 78, 062324 (2008)] the authors put forward an important isomorphism between storing quantum information in a dimension $D$ and transmission of quantum information in a $D+1$-dimensional network. We show that it is possible to obtain long-distance entanglement in a noisy two-dimensional (2D) network, even when taking into account that encoding and decoding of a state is exposed to an error. For 3D networks we propose a simple encoding and decoding scheme based solely on syndrome measurements on 2D Kitaev topological quantum memory. Our procedure constitutes an alternative scheme of state injection that can be used for universal quantum computation on 2D Kitaev code. It is shown that the encoding scheme is equivalent to teleporting the state, from a specific node into a whole two-dimensional network, through some virtual EPR pair existing within the rest of network qubits. We present an analytic lower bound on fidelity of the encoding and decoding procedure, using as our main tool a modified metric on space-time lattice, deviating from a taxicab metric at the first and the last time slices.

description: In the present paper, we consider the problem of matrix completion with noise. Unlike previous works, we consider quite general sampling distribution and we do not need to know or to estimate the variance of the noise. Two new nuclear-norm penalized estimators are proposed, one of them of "square-root" type. We analyse their performance under high-dimensional scaling and provide non-asymptotic bounds on the Frobenius norm error. Up to a logarithmic factor, these performance guarantees are minimax optimal in a number of circumstances.

Heterosexual tensions within Canadian neoliberalism : young South Asian women’s negotiations toward sexual autonomy
Creators: name: Dhillon, Michelle
Publisher: name: University of British Columbia
Year: 2014

description: With the proliferation of neoliberal discourse in the West, there has been a congruous emphasis on the sexual freedoms purportedly available to young women. While navigating gendered, racialized, and ethnically-grounded understandings of and expectations for their heterosexuality, young women are simultaneously compelled to understand themselves as sexually ‘empowered,’ able to freely dictate the terms of their heterosexual desire and behaviour. Exploring the experiences of young, heterosexually-active South Asian women in Vancouver and the Lower Mainland, my research builds upon a burgeoning area of scholarship considering these contradictions of contemporary femininity. Through a thematic analysis of data generated through focus group discussions, with a total of twelve participants, I consider how these young South Asian women experience and make meaning of their heterosexual desire and behaviour. Ultimately, I found participants’ heterosexual experiences to be characterized by their negotiation of a central tension: while their sexual freedoms remain conditional and constrained, these young South Asian women nonetheless constructed themselves as fully in control of their heterosexual experiences and, accordingly, as individually responsible for effectively navigating any restrictive understandings or expectations that may threaten their sexual autonomy. In the following analytic discussion, I trace this tension through participants’ navigation of the heterosexual expectations encompassed within an idealized notion of South Asian femininity, efforts to work through moralistic understandings of heterosexuality, and pursuit of wanted and pleasurable heterosexual encounters.

description: Parenterale Fettemulsionen sind gut untersucht und bewährt als Träger für lipophile Arzneistoffe. Zur Vereinfachung von Screeningprozessen für lipophile Arzneistoffe, wurde die Anwendung der dualen asymmetrischen Zentrifugierung als eine alternative Herstellungstechnik für kleine Probenmengen untersucht. Es war möglich physiologisch verträgliche Nanoemulsionen mit dieser Methode herzustellen. Die Charakterisierung der Partikelgröße und der Partikelgrößenverteilung erfolgte mittels Lichtstreuung. Die Stabilität der Emulsionen wurde durch regelmäßige Messungen der Partikelgröße, des Zetapotentials, des pH-Wertes und der Osmolalität gezeigt. Die etablierte Methode zur Herstellung konnte auch mit leicht veränderten Formulierungen verwendet werden. Außerdem wurden lipophile Arzneistoffe eingearbeitet. Die Emulsionsbildung erfolgte über zwei halbfeste Zwischenschritte. Deren Aussehen und Strukturen wurden mit mehreren Methoden, wie Polarisationsmikroskopie, Gefrierbruchelektronenmikroskopie und Benchtop-NMR untersucht. Ihre Stabilität wurde unter verschiedenen Bedingungen getestet. Ein Zusammenhang zwischen dem Aussehen der Zwischenschritte und der Qualität des Endproduktes konnte hergestellt werden.
description: Parenteral fat emulsions are well established as drug delivery systems for lipophilic drugs. The applicability of dual asymmetric centrifugation as an alternative technique to produce small amounts of nanoemulsions was investigated. With this method physiological tolerable nanoemulsions could be prepared which facilitates screening processes for active pharmaceutical ingredients. The droplet size and droplet size distribution was determined by light scattering. Stability was shown by repeated measurements of particle size, zeta potential, pH and osmolality. The established procedure could also be applied for modified formulations. Active ingredients were successfully incorporated. During the process of emulsification two semisolid intermediate steps were formed. Their appearance and structure was investigated with several methods, e. g. light microscopy, electron transmission microscopy and benchtop nuclear magnetic resonance. Stability under different conditions was examined. The observed intermediate step was important for predicting the quality of the final product.

description: We propose dimension reduction methods for sparse, high-dimensional multivariate response regression models. Both the number of responses and that of the predictors may exceed the sample size. Sometimes viewed as complementary, predictor selection and rank reduction are the most popular strategies for obtaining lower-dimensional approximations of the parameter matrix in such models. We show in this article that important gains in prediction accuracy can be obtained by considering them jointly. We motivate a new class of sparse multivariate regression models, in which the coefficient matrix has low rank and zero rows or can be well approximated by such a matrix. Next, we introduce estimators that are based on penalized least squares, with novel penalties that impose simultaneous row and rank restrictions on the coefficient matrix. We prove that these estimators indeed adapt to the unknown matrix sparsity and have fast rates of convergence. We support our theoretical results with an extensive simulation study and two data analyses.

description: We study global scale invariance along with the unimodular gravity in the vacuum. The global scale invariant gravitational action which follows the unimodular general coordinate transformations is considered without invoking any scalar field. This is generalization of conformal theory described in the Ref. \cite{Mannheim}. The possible solutions for the gravitational potential under static linear field approximation are discussed. The new modified solution has additional corrections to the Schwarzschild solution which describe the galactic rotational curve. A comparative study of unimodular theory with conformal theory is also presented. Furthermore, the cosmological solution is studied and it is shown that the unimodular constraint preserve the de Sitter solution explaining the dark energy of the universe.

description: We study the effect of nuclear matter in Upsilon production in dAu collisions at RHIC and pPb collisions at the LHC. We find that the nuclear modification factor, R^Upsilon_dAu, measured at RHIC is not satisfactorily reproduced by the conventional effects used in the literature, namely the modification of the gluon distribution in bound nucleons and an --effective-- survival probability for a bound state to escape the nucleus. In particular, we argue that this probability should be close to 1 as opposed to the J/psi case. We note that, at backward rapidities, the unexpected suppression of R^Upsilon_dAu observed by PHENIX hints at the presence of a gluon EMC effect, analogous to the quark EMC effect -- but likely stronger. Further nuclear matter effects, such as saturation and fractional energy loss, are discussed, but none of them fit in a more global picture of quarkonium production. Predictions for Upsilon(nS) for the forthcoming pPb run at 5 TeV at the LHC are also presented.

description: An investigation has been made to predict the effects of forebody and afterbody as one of the pivotal initiatives of Saudi Arabia's Vision 2030; the human capabilities development program is a beacon of hope, aiming to enhance the skills of citizens and boost global competitiveness. As a critical project under this initiative, the Ministry of Education has been diligently updating educational programs to meet the needs of the global job market. In line with these efforts, this study investigates the alignment of architectural education in Saudi Arabia with labour market demands and international accreditation requirements. Using curricula of fourteen local architectural programs and Junior Jobs required skills and knowledge from International Architectural Firms. The study achieves its objectives through a comprehensive survey of local educational institutes, tabulating their curriculums, and identifying the main topics, categories, and sections of these curriculums. The study then compares the curricula to international accreditation requirements and market-required skills and knowledge. Results highlight gaps, including business practice background knowledge, problem-solving skills, analytical skills, experience with modern construction materials and techniques, and advanced knowledge of computer tools. Finally, specific fields to be enhanced within the curricula to increase the readiness of the graduates were introduced. Moreover, the study recommended cooperation actions between the three directing parties of the education process: professional associations, educational institutions, and accrediting organizations.
Discord, intransigence, ambivalence, and ultimate coherence : relationships between the musical surface and its underlying structures in Fauré’s nocturne no. 6, op. 63
Creators: name: Lin, Hoi Wai

description: The Sixth Nocturne of Gabriel Fauré has long been acclaimed and widely performed. However, its musical and compositional values sadly lack reflection in the music-analytical literature. The Nocturne’s style is eclectic, incorporating chromatic, modal, and non-tonal (symmetric) collections into diatonic tonality. That the frame of traditional, functional tonality is made to accommodate these diverse constructs suggests many questions and implies the need for advanced analysis. In Chapter 1 I identify specific complexities encountered in this work, including deformed voice leading, temporally skewed counterpoint, subtle metric dissonance, recourse to the whole-tone and octatonic collections, modal mixture in local and global context, and ambiguity of tonic and dominant functions. Their presence serves as my justification in searching for a simpler, more fundamental and continuous underlying structure, of the sort aimed at by Schenkerian analysis. Because this type of analysis must be adapted for late nineteenth-century music, the Chapter also summarizes prior work along these lines that I found suggestive. A 1993 article by Edward Phillips was of primary importance to me, but I also summarize noteworthy contributions by James Sobaskie, Taylor Greer and Robert Morgan. Chapter 2 presents a complete Schenkerian two-leveled graph (the standard background graph is omitted), accompanied by a detailed commentary. Finally, Chapter 3 summarizes four significant structural features of the Nocturne that my experience suggests are of general importance to the composer’s style. They are 1) Discord: when what may seem “wrong” at the surface sounds “right” at a deeper level; 2) Intransigence: conflict in the harmonic-melodic structure due to skewed counterpoint and persisting, sometimes migratory scale degrees; 3) Ambivalence: blurring between tonic and dominant harmonies and 4) Coherence: modality and mixture in the large and the small. Ultimately, I hope this study successfully portrays the delightful equilibrium that constitutes the distinctive “flavor of Fauré”––between innovation and tradition, the clouded and the clear, the conflicted and the concordant; and that it captures some of the ways in which these balances operate, thereby shedding additional aesthetic light on one of the gems of the piano repertoire.

description: In clinical practice, physicians make a series of treatment decisions over the course of a patient's disease based on his/her baseline and evolving characteristics. A dynamic treatment regime is a set of sequential decision rules that operationalizes this process. Each rule corresponds to a decision point and dictates the next treatment action based on the accrued information. Using existing data, a key goal is estimating the optimal regime, that, if followed by the patient population, would yield the most favorable outcome on average. Q- and A-learning are two main approaches for this purpose. We provide a detailed account of these methods, study their performance, and illustrate them using data from a depression study.

The Unruh-deWitt Detector and the Vacuum in the General Boundary formalism

description: We discuss how to formulate a condition for choosing the vacuum state of a quantum scalar field on a timelike hyperplane in the general boundary formulation (GBF) using the coupling to an Unruh-DeWitt detector. We explicitly study the response of an Unruh-DeWitt detector for evanescent modes which occur naturally in quantum field theory in the presence of the equivalent of a dielectric boundary. We find that the physically correct vacuum state has to depend on the physical situation outside of the boundaries of the spacetime region considered. Thus it cannot be determined by general principles pertaining only to a subset of spacetime.

The multiple-slit version of Loewner's differential equation and pointwise Hölder continuity of driving functions
Creators: name: Schleißinger, Sebastian
Publisher: name: arXiv
Year: 2012
Subjects: subject: Complex Variables (math.CV)
subject: FOS: Mathematics

description: We consider the chordal Loewner differential equation for multiple slits in the upper half-plane and relations between the pointwise Hölder continuity of the driving functions and the generated hulls. The first result generalizes a result of Lind that gives a sufficient condition for driving functions to generate simple curves. The second result translates the property that the hulls locally look like straight lines at their starting points into a condition for the driving functions.

The use of Quality Talk to foster critical thinking in a low socio-economic secondary Geography Classroom (Accepted Manuscript).pdf
Creators: name: Davies, Maree
name: Esling, Simon
Publisher: name: The University of Auckland
Year: 2021
Subjects: Education

description: This small case study investigated the use of the Quality Talk framework to empower students to pool their knowledge in group discussions around a novel topic or event. The main goals of the Quality Talk approach were to provide teachers with a prescriptive framework for increasing their students’ critical-analytical thinking by providing greater opportunity for student voice. The quasi-experimental methodology involved students and a teacher from a low socio-economic secondary school in a large city in New Zealand in the curriculum area of Geography. The students, on self-report, identified as coming from predominantly Pasifika backgrounds. Following the intervention and additional opportunities to conduct group discussions, many of the students identified how other opinions contributed to their understanding of the topic. An episode of talk is considered a ‘dialogic spell’, rather than a discussion, if the discussion begins with a student’s question and is followed by at least two more questions from other students. When students used higher numbers of uptake questions and high-level questions, they increased their levels of ‘dialogic spell’. The students’ increase of critical-analytical thinking in their pre- and post-test was assessed and graded. The study was important because it also showed that when the teacher relinquished their role as facilitator of the discussions, the students self-facilitated the dialogue amongst themselves.

description: We track the secondary bifurcations of coherent states in plane Couette flow and show that they undergo an incomplete periodic doubling cascade that ends with a crisis bifurcation. We introduce a symbolic dynamics for the orbits and show that the ones that exist fall into the universal sequence described by Metropolis, Stein and Stein for unimodal maps. The periodic orbits cover much of the turbulent dynamics in that their temporal evolution overlaps with turbulent motions when projected onto a plane spanned by energy production and dissipation.
