description: In this letter, we address the question of whether the almost four standard deviations difference between theory and experiment for the muon anomalous magnetic moment $a_μ$ can be explained as a higher-order Standard Model perturbation effect in the pion form factor measurements. This question has, until now, remained open, obscuring the source of discrepancies between the measurements. We calculate the last radiative corrections for the extraction of the pion form factor, which were believed to be potentially substantial enough to explain the data within the Standard Model. We find that the corrections are too small to diminish existing discrepancies in the determination of the pion form factor for different kinematical configurations of low-energy BABAR, BESS-III and KLOE experiments. Consequently, they cannot noticeably change the previous predictions for $a_μ$ and decrease the deviations between theory and direct measurements. To solve the above issues, new data and better understanding of low-energy experimental setups are needed, especially as new direct $a_μ$ measurements at Fermilab and J-PARC will provide new insights and substantially shrink the experimental error.

description: Failure to find homogeneous scalar unitary cellular automata (CA) in one dimension led to consideration of only ``approximately unitary'' CA---which motivated our recent proof of a No-go Lemma in one dimension. In this note we extend the one dimensional result to prove the absence of nontrivial homogeneous scalar unitary CA on Euclidean lattices in any dimension.

description: The exceptional electronic and spintronic properties of magnetic Heusler alloys, which include half-metals and Weyl semimetals, are strongly sensitive to deviations from the ideal atomic structure. To ensure that these materials have been produced with the desired properties, it is necessary to determine both the structural ordering and the electronic structure, which can be challenging. Here, we present the results of a far-infrared-to-visible optical spectroscopy study of films of room-temperature ferromagnetic Weyl semimetal Co2MnGa. Combined with a determination of the level of ordering from x-ray diffraction, we have investigated near Fermi energy valence and conduction band intra- and interband transitions and their dependence on the atomic order. Motivated by band structure calculations, we have modeled our optical spectra with two Drude terms and two Lorentz oscillators, where the latter are assigned to interband transitions. The scattering rate of the itinerant carriers, determined from the width of the Drude term, increases threefold with increasing disorder, while the carrier density to effective mass ratio is unchanged. Based on our band structure and the joint density of states calculations, we have assigned the oscillator that dominates the interband spectral region near 1 eV to transitions across the minority spin gap along the Γ-X direction. It is found that the energy of this transition is strongly sensitive to the degree of order and decreases rapidly with increasing disorder as states fill a decreasing minority spin gap. Our results demonstrate optical spectroscopy is a sensitive way to fingerprint structural order in the technologically relevant near Fermi level electronic states in Heusler alloys.
title: A change agent for improving quality: The educational leader in Australian early childhood education and care

description: Recognising the importance of effective leadership in early childhood education and care (ECEC), the Australian Government mandated an educational leader role be created within ECEC services as part of the National Quality Reform Agenda. This study seeks to understand the educational leader role and its potential for improving quality in ECEC through the lived experiences of those most influenced by this reform: educational leaders and early childhood professionals (directors, teachers, and educators who are not the educational leader) employed in approved prior-to-school ECEC services. These services include long day care, kindergarten, preschool, and family day care. The study employed a mixed methods phenomenological approach with an explanatory, sequential, qualitative dominant design. Data were collected in two phases. Phase One involved an online national survey involving ECEC professionals from all states and territories, with analysis of this first phase (n = 279) providing a broad understanding of the educational leader role from the perspective of both educational leaders (n = 207) and early childhood professionals (n = 70). Phase Two of the study provided a deeper insight into the role, with data gathered through semi-structured interviews (n = 22), again from the perspective of both educational leaders and early childhood professionals. The findings indicate that while the majority of participants perceive the educational leader role to be beneficial, many are concerned about how the role is being implemented and perceive the role to be working only sometimes and in some ways. A lack of attention to contextual factors influencing leadership has limited the potential of leadership provided by the educational leader. In response to these findings an ECEC Leadership for Improving Quality Framework was developed. This framework is also informed by key literature from three interrelated fields: quality in ECEC, leadership, and educational change. It is presented in the conclusion of this thesis in order to inform the discourse around leadership in ECEC, to support the processes used to improve quality, and to inform further policy and reform.

description: This paper reports on two case studies concerning young children’s reasoning about human actions on nature. In each study, children are presented with a different plausible scenario of tree logging, before and after a teaching intervention. The latter has to do with trees as animal-habitats and is set in the broader context of Education for Sustainable Development. We are discussing the possible impact of the teaching intervention as well as that of the probing scenarios, on children’s attitudes for tree logging and on the ways they justify them.

A geometric approach to the sup-norm problem for automorphic forms: the case of newforms on $GL_2(\mathbb F_q(T))$ with squarefree level
Creators: name: Sawin, Will
Publisher: name: arXiv
Year: 2019
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: The sup-norm problem in analytic number theory asks for the largest value taken by a given automorphic form. We observe that the function-field version of this problem can be reduced to the geometric problem of finding the largest dimension of the $i$th stalk cohomology group of a given Hecke eigensheaf at any point. This problem, in turn, can be reduced to the intersection-theoretic problem of bounding the "polar multiplicities" of the characteristic cycle of the Hecke eigensheaf, which in known cases is the nilpotent cone of the moduli space of Higgs bundles. We solve this problem for newforms on $GL_2 (\mathbb A_{\mathbb F_q(t)})$ of squarefree level, leading to bounds on the sup-norm that are stronger than what is known in the analogous problem for newforms on $GL_2(\mathbb A_{\mathbb Q})$ (i.e. classical holomorphic and Maass modular forms.)

We consider the problem from the information engine point of view. The circuit synthesis as a whole and different steps of the design process (an example of decision diagram is given) are presented via such measurements as entropy, logical work and information vitality. We also introduce new information measures to provide better estimates of synthesis criteria. We show that the basic properties of information engine, such as the conservation law of information flow and the equilibrium law of information can be formulated.

description: The first part of this paper extends the Doplicher-Haag-Roberts theory of superselection sectors to quantum field theory on arbitrary globally hyperbolic spacetimes. The statistics of a superselection sector may be defined as in flat spacetime and each charge has a conjugate charge when the spacetime possesses non-compact Cauchy surfaces. In this case, the field net and the gauge group can be constructed as in Minkowski spacetime. The second part of this paper derives spin-statistics theorems on spacetimes with appropriate symmetries. Two situations are considered: First, if the spacetime has a bifurcate Killing horizon, as is the case in the presence of black holes, then restricting the observables to the Killing horizon together with "modular covariance" for the Killing flow yields a conformally covariant quantum field theory on the circle and a conformal spin-statistics theorem for charged sectors localizable on the Killing horizon. Secondly, if the spacetime has a rotation and PT symmetry like the Schwarzschild-Kruskal black holes, "geometric modular action" of the rotational symmetry leads to a spin-statistics theorem for charged covariant sectors where the spin is defined via the SU(2)-covering of the spatial rotation group SO(3).

The model of situational teaching that we developed and tested shows the feasibility of the first two stages, namely professional transposition content to teach in a Repository Professional Skills, situational transposing it into a Repository declined in didactic training situations. In order to assess the contributions and limitations of this model, we gathered feedback from students, before and after training, through two questionnaires. The results show a positive trend in the mastery and skills transfer for professional communication and mobilization in a real situation during the internship.

description: The aim of this thesis was to investigate the use of mobile phones as an adjunct to face-to-face psychotherapy. This aim was developed from two structured reviews of the literature concerning the types of adjunctive technologies in use, and the ways in which they have been used to increase adherence. Adjunctive use of the mobile phone was investigated in regards to its capacity to achieve greater client adherence and engagement in therapy, in order to facilitate improved treatment outcomes and client satisfaction. This overarching aim and hypothesis was investigated in three empirical studies, presented as a series of published and unpublished papers. Study One investigated the use of Short Message Service (SMS) appointment reminders. It was predicted that the SMS prompts, delivered the day prior to a scheduled appointment at an outpatient psychology clinic, would decrease client non­ attendance and dropout. In a Randomised Controlled Trial (RCT), 140 participants were allocated to either receive SMS appointment reminders or to receive no reminders. No significant differences were found between the two conditions in relation to client attendance. Dropout was higher in the SMS condition than in the no SMS condition. It was concluded that the SMS reminders did not increase client adherence to appointment attendance behaviours. This study also highlighted the importance of careful examination of technological interventions before dissemination.

description: In this paper, we provide a conceptual new construction of the algebraic structure on the pair of the Hochschild cohomology spectrum (cochain complex) and Hochschild homology spectrum, which is analogous to the structure of calculus on a manifold. This algebraic structure is encoded by a two-colored operad introduced by Kontsevich and Soibelman. We prove that for a stable idempotent-complete infinity-category, the pair of its Hochschild cohomology and homology spectra naturally admits the structure of algebra over the operad. Moreover, we prove a generalization to the equivariant context.

School workshops or workplace? Moreover, who is the appropriate teacher? Is it the VET teacher or the VET workplace trainer? In this research we have tried to elicit, within the theoretical framework of vocational didactics, what is a professional task for vocational school teachers and for practitioners who exercise such tasks in workplace. The recording of oral descriptions was employed as method. Clear differences were registered between the descriptions of teachers and practitioners which are attempted to be explained in this work. Implications regarding vocational education and research are discussed.

description: The fractal properties of models of randomly placed $n$-dimensional spheres ($n$=1,2,3) are studied using standard techniques for calculating fractal dimensions in empirical data (the box counting and Minkowski-sausage techniques). Using analytical and numerical calculations it is shown that in the regime of low volume fraction occupied by the spheres, apparent fractal behavior is observed for a range of scales between physically relevant cut-offs. The width of this range, typically spanning between one and two orders of magnitude, is in very good agreement with the typical range observed in experimental measurements of fractals. The dimensions are not universal and depend on density. These observations are applicable to spatial, temporal and spectral random structures. Polydispersivity in sphere radii and impenetrability of the spheres (resulting in short range correlations) are also introduced and are found to have little effect on the scaling properties. We thus propose that apparent fractal behavior observed experimentally over a limited range may often have its origin in underlying randomness.

Subjects: Economics

description: While previous literature has emphasized the importance of energy and public infrastructure services for economic development, questions surrounding the implications of unequal spatial distribution in access to these resources remain, particularly in the developing country context.  This dissertation provides evidence on the nature, origins and implications of this distribution uniting three strands of research from the development and political economy, regional science and energy economics fields. The dissertation unites three papers on the nature of spatial inequality of access to energy and infrastructure with further implications for conflict risk , the historical institutional and biogeographical determinants of current distribution of access to energy and public infrastructure services and the response of households to fuel price changes over time. Chapter 2 uses a novel survey dataset to provide evidence for spatial clustering of public infrastructure non-functionality at schools by geopolitical zone in Nigeria with further implications for armed conflict risk in the region. Chapter 3 investigates the drivers of the results in chapter 2, exploiting variation in the spatial distribution of precolonial institutions and geography in the region, to provide evidence for the long-term impacts of these factors on current heterogeneity of access to public services. Chapter 4 addresses the policy implications of energy access, providing the first multi-year evidence on firewood demand elasticities in India, using the spatial variation in prices for estimation.

description: A new method for deriving universal Ř matrices from braid group representation is discussed. In this case, universal Ř operators can be defined and expressed in terms of products of braid group generators. The advantage of this method is that matrix elements of Ř are rank independent, and leaves multiplicity problem concerning coproducts of the corresponding quantum groups untouched. As examples, Ř matrix elements of $[1]\times [1]$, $[2]\times [2]$, $[1^{2}]\times [1^{2}]$, and $[21]\times [21]$ with multiplicity two for $A_{n}$, and $[1]\times [1]$ for $B_{n}$, $C_{n}$, and $D_{n}$ type quantum groups, which are related to Hecke algebra and Birman-Wenzl algebra, respectively, are derived by using this method.

subject: Sustainable development--Government policy

description: This dissertation examines the relationship between political institutions and development policies across a wide array of policy arenas. It consists of three essays. In the first essay, I examine how corruption in political institutions affects citizens’ attitudes towards proposed policy reforms that should yield long-run benefits. I argue that where corruption in political institutions reduces citizens’ benefits from existing programs, governmental promises to deliver benefits via reforms are less credible. Thus, citizens will cling to inefficient policies not because they are unable to recognize the benefits of reform but because they do not trust political institutions to implement reforms in ways that will benefit them in practice. I use this logic to explain why citizens frequently resist attempts to reform the economically and environmentally costly practice of setting domestic gasoline prices below market prices. To reveal these patterns, I rely on original survey and administrative data from Indonesia. The second essay maintains the focuses on the quality of political institutions and natural resource governance but from a more macro perspective. In this essay, I argue that political regimes and political time horizons shape financial arrangements between governments and multinational oil companies. This essentially asks the reverse of a central question in comparative politics. Rather than asking how oil income affects political institutions, I ask how political institutions motivate politicians to make policy choices that increase or decrease the government’s access to oil income over time. To do so, I utilize an original dataset on financial arrangements between host countries and multinational oil companies, as reflected in historically confidential oil contracts. The final essay travels to a different substantive area of development policy, yet allows for a critical role for political institutions. This essay argues that the relationship between developing country governments and foreign aid donors should be conditional on the quality of political institutions, with aid donors giving countries with institutions better able to commit to selecting policies that promote development wider latitude to direct foreign aid resources towards local priorities. Instead, I find that political and security alliances shape whether donors give developing country governments more “ownership” over aid flows. Overall, the dissertation deepens understanding of the relationship between the quality of political institutions and policies within developing countries, while offering insights into contemporary policy debates about natural resource governance, environmental politics, and development aid.

description: Leveraging size effects, nanoparticles of metal-organic frameworks, nanoMOFs, have recently gained traction, amplifying their scopes in electrochemical sensing. However, their synthesis, especially under eco-friendly ambient conditions remains an unmet challenge. Herein, an ambient and fast secondary building unit (SBU)-assisted synthesis (SAS) route to afford a prototypal porphyrinic MOF, Fe-MOF-525 is introduced. Albeit the benign room temperature conditions, Fe-MOF-525(SAS) nanocrystallites obtained are of ≈30 nm size, relatively smaller than the ones conventional solvothermal methods elicit. Integrating Fe-MOF-525(SAS) as a thin film on a conductive indium tin oxide (ITO) surface affords Fe-MOF-525(SAS)/ITO, an electrochemical biosensor. Synergistic confluence of modular MOF composition, analyte-specific redox metalloporphyrin sites, and crystal downsizing contribute to its benchmark voltammetric uric acid (UA) sensing. Showcasing a wide linear range of UA detection with high sensitivity and low detection limit, this SAS strategy coalesces ambient condition synthesis and nanoparticle size control, paving a green way to advanced sensors.
Essays on the Financial Sector Inefficiencies

description: This dissertation investigates the sources of inefficiencies in financial sector and effects of these inefficiencies on the economy. In the first chapter, I analyze the effects of asset prices on financial institutions in a dynamic stochastic general equilibrium model including bank defaults and related agency costs. I find that pecuniary externalities exist in asset prices as decentralized banks do not internalize the effects of their lending on asset price distributions. These externalities lead to excess risk taking and leverage in the financial sector. Excess risk taking behavior deteriorates welfare of both depositors and banks in a stochastic economy. I show that a restricted social planner is able to improve welfare by limiting the leverage in the economy. In planner's problem, robust banking system is more resilient against the shocks. This in turn creates more stable economy with lower bankruptcy costs and increases welfare. Thus, I show that significant economic gains are possible with appropriate regulations in the financial sector.  In the second chapter, I examine the welfare effects of pecuniary asset price externalities using a dynamic stochastic general equilibrium model. I show that decentralized financial system is socially inefficient due to pecuniary price externalities. I compare various regulations using quantitative welfare analysis. I find that bailout policies cause moral hazard problems and induce excess risk taking. Therefore, such policies worsen the inefficiency. However, macro-prudential policies limit the leverage and provide resilience against the systemic shocks. Thus, these policies mitigate distortions and improve welfare. Furthermore, I show that combination of bailout and prudential reserve requirement policies is pareto better than other regulations. Finally, I introduce credit default swaps (CDS) into the model and find that CDSs can mitigate the distortions. But the benefits of CDSs are limited to the size of systemic shocks. If systemic shocks are big enough, CDS linkages will make crisis contagious among the financial institutions. In the third chapter, I analyze the impacts of asymmetric information and imperfect monitoring on financial sector using a single period model with agency costs. I solve the model analytically comparing different levels of imperfect monitoring on heterogeneous banks. I find that information asymmetries and noises in monitoring encourage risk taking behaviors among the banks with low loan returns. I also show that these asymmetries cause inefficiently low lending among banks with high loan returns. In the extension of the model, I analyze government's incentive to prevent asymmetric information using regulatory tools such as stress tests. I analytically show that if the government is elected for short term and the rate of low return banks is high in the economy, government won't have incentive to announce real type of the banks.

This work takes on socio-constructivist approach in order to study the activity of the teacher and the students. The video data analysis of the didactic engineering have been recorded with the software Kronos. Our results show a more important student's speaking time during the debate when they have written hypothesis before. And this difference occurs differently according to the themes reached during the debate.

description: Person retrieval aims at matching person images across multiple non-overlapping camera views. It has facilitated a wide range of important applications in intelligent video analysis. The task of person retrieval remains challenging due to dramatic changes on visual appearance that are caused by large intra-class variations from human pose and camera viewpoint, misaligned person detection and occlusion. How to learn discriminative features under these challenging conditions becomes the core issue for the task of person retrieval. According to the input modality, person retrieval could be categorised into image-based retrieval and video-based retrieval. Despite decades of efforts, person retrieval is still very challenging and remains unsolved due to the following factors: 1) the large intra-class variations (e.g., pose variation) of pedestrian images, leading to a dramatic change in their appearances; 2) only heuristically coarse-grained region strips or pixel-level annotations directly borrowed from pretrained human parsing models are employed, impeding the efficacy and practicality of region representation learning; 3) absence of useful temporal cues for boosting the video person retrieval system; This thesis reports a series of technical solutions towards addressing the above challenges in person retrieval. To address the large intra-class variations among the person images, we introduce an improved triplet loss such that the global feature representations from the same identity are closely clustered for person retrieval. To learn a discriminative region representation within fine-grained segments while avoiding expensive pixel-level annotations, we introduce a novel identityguided human region segmentation method that can predict informative region segments, enabling discriminative region representation learning for person retrieval. To extract useful temporal cues for video person retrieval, we build a two-stream architecture, named appearance-gait network, to jointly learn the appearance features and gait feaures from RGB video clips and silhouette video clips. To further provide potentially useful information for person retrieval, we introduce a lightweight and effective knowledge distillation method for facial landmark detection. We believe that the proposed person retrieval approaches can serve as benchmark methods and provide new perspectives for the person retrieval task.

description: The integrated low-level trigger and data acquisition (TDAQ) system of the NA62 experiment at CERN is described. The requirements of a large and fast data reduction in a high-rate environment for a medium-scale, distributed ensemble of many different sub-detectors led to the concept of a fully digital integrated system with good scaling capabilities. The NA62 TDAQ system is rather unique in allowing full flexibility on this scale, allowing in principle any information available from the detector to be used for triggering. The design concept, implementation and performances from the first years of running are illustrated.

Psychoacoustically Motivated Audio Declipping Based on Weighted l1 Minimization

description: A novel method for audio declipping based on sparsity is presented. The method incorporates psychoacoustic information by weighting the transform coefficients in the $\ell_1$ minimization. Weighting leads to an improved quality of restoration while retaining a low complexity of the algorithm. Three possible constructions of the weights are proposed, based on the absolute threshold of hearing, the global masking threshold and on a quadratic curve. Experiments compare the restoration quality according to the signal-to-distortion ratio (SDR) and PEMO-Q objective difference grade (ODG) and indicate that with correctly chosen weights, the presented method is able to compete, or even outperform, the current state of the art.

description: It is demonstrated in the context of the simple one-dimensional example of a barrier in an infinite well, that highly complex behavior of the time evolution of a wave function is associated with the almost degeneracy of levels in the process of tunneling. Degenerate conditions are obtained by shifting the position of the barrier. The complexity strength depends on the number of almost degenerate levels which depend on geometrical symmetry. The presence of complex behavior is studied to establish correlation with spectral degeneracy.

description: We consider the cosmological application of a (variant of) relatively newly proposed model \cite{1609.06915} unifying inflation, dark energy, dark matter, and the Higgs mechanism. The model was originally defined using additional non-Riemannian measures but it can be reformulated into effective quintessential model unifying inflation, dark energy and dark matter. Here we demonstrate numerically that it is capable of describing the entire Universe evolution in a seamless way, but this requires some revision of the model setup. The main reason is that there is a strong effective friction in the model, a feature which has been neglected in the pioneer work. This improves the model potential for proper description of the Universe evolution, because the friction ensures a finite time inflation with dynamically maintained low-value slow-roll parameters in the realistic scenarios. In addition, the model predicts the existence of a constant scalar field in late Universe.

description: A series of 3-perfluoroalkylbenzoate esters are synthesised. They tend to exhibit enantiotropic SmA and SmC phases. The clearing points are decreased with increasing the alkoxy chain length and show odd-even effect. With increasing the fluorocarbon chain length, the melting and clearing points increase; however, the SmC phase is suppressed.

description: We study the impact of fission on the production and destruction of translead nuclei during the r-process nucleosynthesis occurring in neutron-star mergers. Abundance patterns and rates of nuclear energy production are obtained for different ejecta conditions using three sets of stellar reaction rates, one of which is based on microscopic and consistent calculations of nuclear masses, fission barriers, and collective inertias. We show that the accumulation of fissioning material during the r process can strongly affect the free neutron abundance after the r-process freeze-out. This leads to a significant impact on the abundances of heavy nuclei that undergo $α$ decay or spontaneous fission, affecting the radioactive energy production by the ejecta at timescales relevant for kilonova emission.

description: We study the Z 3 meta-stable states in the Polyakov loop Nambu-Jona-Lasinio (PNJL) model. These states exist for temperatures above T m ~ 194 MeV and can decay via bubble nucleation. We numerically solve the bounce equation to compute the nucleation rate. We speculate that, in the context of heavy-ion collisions, the likely scenario for the decay of the meta-stable states is via spinodal decomposition.
