title: Reflection
title: A means to faculty engagement in meaningful continuing professional development

Creators: name: Efu, Ifeatu

Year: 2021

description: This study sought to understand reflection as a means to faculty engagement in continuing professional development (CPD) by examining faculty perceptions about reflection; reflection as a tool to facilitate responsibility and participation in professional development (PD) activities; the extent faculty members reflect on their PD needs; and how they identify PD initiatives that aim to enhance their professional growth. To examine these questions, a mixed method study was undertaken with faculty members in a Canadian higher education institution (HEI). Drawing on data from a questionnaire and semi-structured interviews, the extent to which faculty members use reflection as a tool to engage in CPD was revealed. Though faculty members believe that reflection can help inform their practice and professional growth, it is used minimally to inform CPD due to the issues of time and workload, and the types of PDA supported by the college. To promote reflection among faculty members, time for reflection and training on how to engage in critical reflection is necessary. This can only be achieved within a reflective space and environment of trust, especially between faculty members and management in HEIs. With limited research examining how faculty members can identify relevant and meaningful CPD, this study provides a basis for the use of reflection as a means for them to make deliberate and systematic attempts to reflect on their practice. Through reflection, faculty members generate information and knowledge that helps them make meaning of their actions and experiences, and from which learning through meaningful CPD can continue.

Absorption cross section, luminosity of Hawking radiation and cross section in the low-energy approximation were found. We envisage that parameter connected with the existence of a brane imprints its role in the Hawking radiation of the considered fields.

Strong coupling cavity QED using rare-earth-ion dopants in monolithic resonators: what you can do with a weak oscillator

description: We investigate the possibility of achieving the strong coupling regime of cavity quantum electrodynamics using rare earth ions as impurities in monolithic optical resonators. We conclude that due to the weak oscillator strengths of the rare earths, it may be possible but difficult, to reach the regime where the single photon Rabi frequency is large compared to both the cavity and atom decay rates. However reaching the regime where the saturation photon and atom numbers are less than one should be much more achievable. We show that in this `bad cavity' regime, transfer of quantum states and an optical phase shift conditional on the state of the atom is still possible, and suggest a method for coherent detection of single dopants.

description: The measurement of the spin frequency in accreting millisecond X-ray pulsars (AMXPs) is strongly affected by the presence of an unmodeled component in the pulse arrival times called 'timing noise'. We show that it is possible to attribute much of this timing noise to a pulse phase offset that varies in correlation with X-ray flux, such that noise in flux translates into timing noise. This could explain many of the pulse frequency variations previously interpreted in terms of true spin up or spin down, and would bias measured spin frequencies. Spin frequencies improved under this hypothesis are reported for six AMXPs. The effect would most easily be accounted for by an accretion rate dependent hot spot location.

Copositivity and Complete Positivity

Year: 2017
Subjects: subject: Konferenzschrift
subject: 510

description: A real matrix $A$ is called copositive if $x^TAx \ge 0$ holds for all $x \in \mathbb R^n_+$. A matrix $A$ is called completely positive if it can be factorized as $A = BB^T$ , where $B$ is an entrywise nonnegative matrix. The concept of copositivity can be traced back to Theodore Motzkin in 1952, and that of complete positivity to Marshal Hall Jr. in 1958. The two classes are related, and both have received considerable attention in the linear algebra community and in the last two decades also in the mathematical optimization community. These matrix classes have important applications in various fields, in which they arise naturally, including mathematical modeling, optimization, dynamical systems and statistics. More applications constantly arise. The workshop brought together people working in various disciplines related to copositivity and complete positivity, in order to discuss these concepts from different viewpoints and to join forces to better understand these difficult but fascinating classes of matrices.

remembrance
poppy
cenotaph
creative-critical

description: This thesis, through a combination of autobiographical reflections and a consideration of the work of Roland Barthes, offers a new approach to thinking about the British culture of “Remembrance.” Remembrance is here defined as a range of practices, including, in particular, the selling and wearing of the Remembrance Poppy, the Tomb of the Unknown Warrior, the Two Minute Silence held on both Armistice Day and Remembrance Sunday, and the ceremonies held at the Cenotaph on Whitehall. The thesis explores how Remembrance is presented as an uncomplicated and unchanging phenomenon, and considers how this is simply not the case and what follows from this realisation. The thesis employs throughout a method that might be termed “creative-critical” or “post- critical,” which means that it seeks to move beyond the conventional form of the essay or thesis in the hope of finding – and presenting – new insights on a familiar subject. This occurs most obviously in the way in which the thesis has been written, which is close to what is called a “stream-of-consciousness.” Furthermore, the thesis draws heavily from the entire oeuvre of Roland Barthes, whose work has never before been used to analyse Remembrance so thoroughly. The references to Barthes – which are peppered throughout the text – are offered without quotation marks (to signal just how embedded Barthes’s thoughts are with mine), but are instead coloured in blue (as a way of distinguishing his words from my own). The thesis takes the form of four chapters, each of which is based on one of the seasons, beginning with autumn. The thesis plays on the different images and metaphors of each season in order to offer four different (but related) engagements with the question of Remembrance.

description: Reducing the atmospheric haze and enhancing image clarity is crucial for computer vision applications. The lack of real-life hazy ground truth images necessitates synthetic datasets, which often lack diverse haze types, impeding effective haze type classification and dehazing algorithm selection. This research introduces the HazeSpace2M dataset, a collection of over 2 million images designed to enhance dehazing through haze type classification. HazeSpace2M includes diverse scenes with 10 haze intensity levels, featuring Fog, Cloud, and Environmental Haze (EH). Using the dataset, we introduce a technique of haze type classification followed by specialized dehazers to clear hazy images. Unlike conventional methods, our approach classifies haze types before applying type-specific dehazing, improving clarity in real-life hazy images. Benchmarking with state-of-the-art (SOTA) models, ResNet50 and AlexNet achieve 92.75\% and 92.50\% accuracy, respectively, against existing synthetic datasets. However, these models achieve only 80% and 70% accuracy, respectively, against our Real Hazy Testset (RHT), highlighting the challenging nature of our HazeSpace2M dataset. Additional experiments show that haze type classification followed by specialized dehazing improves results by 2.41% in PSNR, 17.14% in SSIM, and 10.2\% in MSE over general dehazers. Moreover, when testing with SOTA dehazing models, we found that applying our proposed framework significantly improves their performance. These results underscore the significance of HazeSpace2M and our proposed framework in addressing atmospheric haze in multimedia processing.

Factors in early termination of family day care service
Creators: name: Bjerring, Barbara Frances
Publisher: name: University of British Columbia
Year: 2011

description: There is an increasing need for day care services for children in most major urban centres on this continent due to marked changes in the patterns of family life, especially the tendency for women to be gainfully employed after marriage. For children under three years of age, family day care is generally considered to be the preferable type of care outside the home. There is an awareness of the need for this type of care in Vancouver, and also an awareness of the limited facilities available. The Department of Day Care Services of The Family Service Centre, in Vancouver, is an agency, which offers both group day care and family day care service. Because there are some parents who make frequent changes in family day care arrangements for their children, and because agency policy prefers that the duration of agency care be at least one year, agency, staff members feel concern about the use being made of family day care services. Also, since the literature based on psychiatric research suggests that frequent changes of substitute mothers is potentially damaging to children, the social workers at the agency are anxious to know whether there are causal factors in the terminations which could be eliminated. The study has been designed as an experience survey, which makes use of a control group defined operationally as stable, and two groups representing short term care and multiple placements. It was expected that there would be identifiable differences between these groups, some of which might prove to be significant. The study has three main objectives. The first objective is to discover the extent of the problem. The second objective is to identify, if possible, the factors involved in early termination of service and frequent replacements. The third objective is to design an instrument which would be of value in future research. In other words, although this was to be at first an experience survey, it also became a pre- evaluative study. Data have been collected from family day care case files and from information supplied by agency staff members. An instrument has been designed for the collection of data from the files. Our findings indicate that a number of factors appear in the family day care cases in various combinations but, of these, only two have proved to be significant. The families in the stable group are significantly more concerned about the quality of care their children receive. Also, in the stable group, there is a significantly higher frequency of adequate communication between the day care mothers and the natural mothers. Our experience with this study has allowed us to conclude tentatively, that early closing or replacement of children is generally due to factors beyond the control of the agency. It is possible, however, that methods could be developed by the agency to encourage better communication between the natural mother and the family day care mother. More research on parental motivation for using day care is indicated.

Variational Methods for Evolution

description: Many evolutionary systems, as for example gradient flows or Hamiltonian systems, can be formulated in terms of variational principles or can be approximated using time-incremental minimization. Hence they can be studied using the mathematical techniques of the field of calculus of variations. This viewpoint has led to many discoveries and rapid expansion of the field over the last two decades. Relevant applications arise in mechanics of fluids and solids, in reaction-diffusion systems, in biology, in many-particle models, as well as in emerging uses in data science. This workshop brought together a broad spectrum of researchers from calculus of variations, partial differential equations, metric geometry, and stochastics, as well as applied and computational scientists to discuss and exchange ideas. It focused on variational tools such as minimizing movement schemes, Gamma convergence, optimal transport, gradient flows, and large-deviation principles for time-continuous Markov processes.
Linking tree community functional change with soil carbon dynamics during secondary succession in a naturally regenerating tropical forest in Panama
Creators: name: Wallwork, Abby
Publisher: name: Lancaster University
Year: 2021

description: Naturally regenerating tropical forests are increasingly important for their role in the global carbon (C) balance, particularly due to their ability to rapidly sequester large amounts of C in aboveground biomass during forest regrowth. Over half of all C in tropical forests is stored belowground, yet in contrast to the predictable pattern aboveground, there is no clear pattern of soil C accumulation with time during forest regrowth, and we are therefore currently unable to predict and increase soil C sequestration during tropical forest regrowth. Soil C turnover and storage depends on the input of plant-derived organic matter which is likely to be affected by shifts in tree community resource-use strategy (functional group) during secondary succession from light-demanding to shade-tolerant species, and the corresponding reduction in litter quality. As tree community composition can differ between forest stands of similar ages, I hypothesised that tree community functional composition would better predict soil C dynamics during secondary tropical forest succession than stand age and specifically, that differences in litter quality between shade-tolerant and light-demanding tree species would influence rates of soil C turnover via litter decay rates and changes to the soil microbial community. The body of work presented in this thesis provides compelling evidence in support of my overarching hypothesis that soil C accumulation is more closely related to tree functional composition than forest age. My studies highlight some of the potential pathways by which tree community composition can influence soil C storage via plant-derived organic matter inputs representing substrate for the soil microbial community. Overall, the research presented in this thesis demonstrates that tree functional composition could be one of the main factors determining belowground C storage and therefore, my work represents an important first step towards using tree functional groups to predict soil C accumulation in secondary tropical forests.

description: Evaluation of policies in recommender systems typically involves A/B testing using live experiments on real users to assess a new policy's impact on relevant metrics. This ``gold standard'' comes at a high cost, however, in terms of cycle time, user cost, and potential user retention. In developing policies for ``onboarding'' new users, these costs can be especially problematic, since on-boarding occurs only once. In this work, we describe a simulation methodology used to augment (and reduce) the use of live experiments. We illustrate its deployment for the evaluation of ``preference elicitation'' algorithms used to onboard new users of the YouTube Music platform. By developing counterfactually robust user behavior models, and a simulation service that couples such models with production infrastructure, we are able to test new algorithms in a way that reliably predicts their performance on key metrics when deployed live. We describe our domain, our simulation models and platform, results of experiments and deployment, and suggest future steps needed to further realistic simulation as a powerful complement to live experiments.

description: Since 1950, mathematicians have become increasingly familiar with the digital computer in their professional practice. Previously, however, many other instruments, now mostly forgotten, were commonly used to compute numerical solutions, generate geometrical objects, investigate mathematical problems, derive new results, and apply mathematics in a variety of scientific contexts. The problem of characterizing the mathematical objects that can be constructed with a given set of instruments frequently prompted deep theoretical investigations, from the Euclidean geometry of constructions with straightedge and compass, to Shannon’s theorem which, in 1941, stated that the functions constructible with a differential analyzer are exactly the solutions of algebraic differential equations. Beyond these mathematical considerations, instruments should also be viewed as social objects of a given time period and cultural tradition that can amalgamate the perspectives of the inventor, the maker, the user, and the collector; in this sense, mathematical instruments are an important part of the mathematical cultural heritage and are thus widely used in many science museums to demonstrate the cultural value of mathematics to the public. This workshop brought together mathematicians, historians, philosophers, collection curators, and scholars of education to address the various approaches to the history of mathematical instruments and compare the definition and role of these instruments over time, with the following fundamental questions in mind – What is mathematical in a mathematical instrument? What kind of mathematics is involved? What does it mean to embody mathematics in a material artefact, and how do non-mathematicians engage with this kind of embodied mathematics?

description: In a liberal evolutionary scenario, mass can escape from a binary during eras of fast mass transfer. We calculate the mass lost by binaries with a B-type primary at birth where mass transfer starts during hydrogen core burning of the donor. We simulate the distribution of mass-ratios and orbital periods for those interacting binaries. The amount of time the binary shows Algol characteristics within different values of mass-ratio and orbital period has been fixed from conservative and liberal evolutionary calculations. We use these data to simulate the distribution of mass-ratios and orbital periods of Algols with the conservative as well as the liberal model. We compare mass-ratios and orbital periods of Algols obtained by conservative evolution with those obtained by our liberal model. Since binaries with a late B-type primary evolve almost conservatively, the overall distribution of mass-ratios will only yield a few Algols more with high mass-ratios than conservative calculations do. Whereas the simulated distribution of orbital periods of Algols fits the observations well, the simulated distribution of mass-ratios produces always too few systems with large values.

The background from single electromagnetic subcascades for a stereo system of air Cherenkov telescopes

description: The MAGIC experiment, a very large Imaging Air Cherenkov Telescope (IACT) with sensitivity to low energy (E < 100 GeV) VHE gamma rays, has been operated since 2004. It has been found that the gamma/hadron separation in IACTs becomes much more difficult below 100 GeV [Albert et al 2008] A system of two large telescopes may eventually be triggered by hadronic events containing Cherenkov light from only one electromagnetic subcascade or two gamma subcascades, which are products of the single pi^0 decay. This is a possible reason for the deterioration of the experiment's sensitivity below 100 GeV. In this paper a system of two MAGIC telescopes working in stereoscopic mode is studied using Monte Carlo simulations. The detected images have similar shapes to that of primary gamma-rays and they have small sizes (mainly below 400 photoelectrons (p.e.)) which correspond to an energy of primary gamma-rays below 100 GeV. The background from single or two electromagnetic subcascdes is concentrated at energies below 200 GeV. Finally the number of background events is compared to the number of VHE gamma-ray excess events from the Crab Nebula. The investigated background survives simple cuts for sizes below 250 p.e. and thus the experiment's sensitivity deteriorates at lower energies.

description: The anisotropic complex dielectric response was accurately extracted from spectroscopic ellipsometry measurements at phonon frequencies for the three principal crystallographic directions of an orthorhombic (Pbnm) YTiO_3 single crystal. We identify all twenty five infrared-active phonon modes allowed by symmetry, 7B_1u, 9B_2u, and 9B_3u, polarized along the c-, b-, and a-axis, respectively. From a classical dispersion analysis of the complex dielectric functions \tildeε(ω) and their inverses -1/\tildeε(ω) we define the resonant frequencies, widths, and oscillator strengths of the transverse (TO) and longitudinal (LO) phonon modes. We calculate eigenfrequencies and eigenvectors of B_1u, B_2u, and B_3u normal modes and suggest assignments of the TO phonon modes observed in our ellipsometry spectra by comparing their frequencies and oscillator strengths with those resulting from the present lattice-dynamics study. Based on these assignments, we estimate dynamical effective charges of the atoms in the YTiO_3 lattice. We find that, in general, the dynamical effective charges in YTiO_3 lattice are typical for a family of perovskite oxides. By contrast to a ferroelectric BaTiO_3, the dynamical effective charge of oxygen related to a displacement along the c-axis does not show the anomalously large value. At the same time, the dynamical effective charges of Y and ab-plane oxygen exhibit anisotropy, indicating strong hybridization along the a-axis.

Mini-Workshop: Cluster Expansions: From Combinatorics to Analysis through Probability
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2017
Subjects: subject: Konferenzschrift
subject: 510

description: The workshop addressed the interplay between theory and applications of cluster expansions. These expansions, historically geared towards the study of systems in statistical mechanics, thermodynamics, and physical chemistry, have recently found applications in different areas of current mathematical research, such as point processes, random graphs, coloring issues, logics and inverse problems in numerical analysis. The workshop developed both directions of the theory–application interplay. On the one hand, speakers presented advances in the theoretical foundations of the abstract polymer model and improved tree-graph inequalities, and explored their consequences for the theory of liquids and other applied issues. On the other hand, researchers in stochastic modelisation exposed needs and challenges brought by concrete models of liquids and liquid crystal to the theory of cluster expansions. In addition other complementary methods were discussed, such as disagrement percolation – an expansion-free approach to uniqueness and decay of correlations – and lace expansions – an expansion technique popular for its applications to random walks and percolation problems.

Multiple condensed phases in attractively interacting Bose systems

subject: FOS: Physical sciences

description: We investigate a Bose gas with finite-range interaction using a scheme to eliminate unphysical processes in the T-matrix approximation. In this way the corrected T-matrix becomes suitable to calculate properties below the critical temperature. For attractive interaction, an Evans-Rashid transition occurs between a quasi-ideal Bose gas and a BCS-like phase with a gaped dispersion. The gap decreases with increasing density and vanishes at a critical density where the single-particle dispersion becomes linear for small momenta indicating Bose-Einstein condensation. The investigation of the pressure shows however, that the mentioned quantum phase transitions might be inaccessible due to a preceding first order transition.
Mini-Workshop: Stochastic Differential Equations: Regularity and Numerical Analysis in Finite and Infinite Dimensions
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2017
Subjects: subject: Konferenzschrift
subject: 510

description: This Mini-Workshop is devoted to regularity and numerical analysis of stochastic ordinary and partial differential equations (SDEs for both). The standard assumption in the literature on SDEs is global Lipschitz continuity of the coefficient functions. However, many SDEs arising from applications fail to have globally Lipschitz continuous coefficients. Recent years have seen a prosper growth of the literature on regularity and numerical approximations for SDEs with non-globally Lipschitz coefficients. Some surprising results have been obtained – e.g., the Euler–Maruyama method diverges for a large class of SDEs with super-linearly growing coefficients, and the limiting equation of a spatial discretization of the stochastic Burgers equation depends on whether the discretization is symmetric or not. Several positive results have been obtained. However the regularity of numerous important SDEs and the closely related question of convergence and convergence rates of numerical approximations remain open. The aim of this workshop is to bring together the main contributers in this direction and to foster significant progress.
Computability Theory

Publisher: name: Zürich : EMS Publ. House
Year: 2018
Subjects: subject: Konferenzschrift
subject: 510

description: Computability and computable enumerability are two of the fundamental notions of mathematics. Interest in effectiveness is already apparent in the famous Hilbert problems, in particular the second and tenth, and in early 20th century work of Dehn, initiating the study of word problems in group theory. The last decade has seen both completely new subareas develop as well as remarkable growth in two-way interactions between classical computability theory and areas of applications. There is also a great deal of work on algorithmic randomness, reverse mathematics, computable analysis, and in computable structure theory/computable model theory. The goal of this workshop is to bring together researchers representing different aspects of computability theory to discuss recent advances, and to stimulate future work.
Mini-Workshop: Entropy, Information and Control
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2018
Subjects: subject: Konferenzschrift
subject: 510

description: This mini-workshop was motivated by the emerging field of networked control, which combines concepts from the disciplines of control theory, information theory and dynamical systems. Many current approaches to networked control simplify one or more of these three aspects, for instance by assuming no dynamical disturbances, or noiseless communication channels, or linear dynamics. The aim of this meeting was to approach a common understanding of the relevant results and techniques from each discipline in order to study the major, multi-disciplinary problems in networked control.
The topological structure of direct limits in the category of uniform spaces

description: Let $(X_n)_{n}$ be a sequence of uniform spaces such that each space $X_n$ is a closed subspace in $X_{n+1}$. We give an explicit description of the topology and uniformity of the direct limit $u-lim X_n$ of the sequence $(X_n)$ in the category of uniform spaces. This description implies that a function $f:u-lim X_n\to Y$ to a uniform space $Y$ is continuous if for every $n$ the restriction $f|X_n$ is continuous and regular at the subset $X_{n-1}$ in the sense that for any entourages $U\in\U_Y$ and $V\in\U_X$ there is an entourage $V\in\U_X$ such that for each point $x\in B(X_{n-1},V)$ there is a point $x'\in X_{n-1}$ with $(x,x')\in V$ and $(f(x),f(x'))\in U$. Also we shall compare topologies of direct limits in various categories.

Subjects: subject: Konferenzschrift
subject: 510

description: Machine learning and in particular deep learning offer several data-driven methods to amend the typical shortcomings of purely analytical approaches. The mathematical research on these combined models is presently exploding on the experimental side but still lacking on the theoretical point of view. This workshop addresses the challenge of developing a solid mathematical theory for analyzing deep neural networks for inverse problems.

Longitudinal permeability within Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) growth increments
Creators: name: Bramhall, George
Publisher: name: University of British Columbia
Year: 2011

description: An apparatus was constructed to measure the longitudinal gas-permeability of wood microsections about 150 microns thick. This apparatus was used to examine low surface tension drying methods of wood (freeze-drying and alcohol-benzene extraction) believed to maintain the bordered pit tori of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) in the non-aspirated condition. Results were compared with drying methods believed to aspirate tori (air-drying, oven-drying and boiling-under-vacuum). Dry nitrogen gas-permeability measurements were made under "steady state" conditions. Similar drying techniques were used to prepare gross specimens which were subsequently subjected to “non-steady state" pressure treatment in end-penetration. Sapwood and heartwood specimens from impermeable interior-type and permeable coast-type Douglas fir were tested. With both gross sections and microsections, the two low surface tension drying methods provided more permeable wood than did air-drying. Boiling-under-vacuum was as effective as low surface tension methods in improving gas-permeability, but not creosote-permeability, whereas oven-drying was as effective as low surface tension methods in improving creosote-permeability, but not gas-permeability. The improvement was most striking in all sapwood samples, less in coast-type heartwood, and nil or not measurable in interior-type heartwood. Under the experimental conditions, latewood gas-permeability was about 2 darcies for all specimens and drying methods. Heartwood early-wood gas-permeability ranged from 0.02 to 2 darcies but was unaffected by drying methods. Sapwood earlywood gas-permeability was improved from 8 to 30 times by low surface tension drying. The greatest gas-permeability was found in the first-formed earlywood, which ranged from 2 to 100 darcies. The later-formed earlywood ranged from 0.02 to 100 darcies, depending on wood origin and drying method. Creosote-permeability of interior-type heartwood was uniformly low by all drying methods. Interior-type sapwood and coast-type sapwood and heartwood were much more permeable after low surface tension drying or oven-drying. By visual observations, after all drying methods, latewood was more permeable than earlywood. Low surface tension drying methods improve earlywood gas-permeability of sapwood, and latewood creosote-permeability of sapwood and coast-type heartwood.
