description: We report the discovery of 28 candidate high-velocity stars (HVSs) at heliocentric distances of less than 3 kpc, based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 1. Our sample of HVS candidates covers a much broader color range than the equivalent ranges discussed in previous studies and comprises the first and largest sample of HVSs in the solar neighborhood. The sufficiently accurate observed and derived parameters for all candidates allow us to ascertain their nature as genuine HVSs, while a subset of 12 objects represents the most promising candidates. Our results also highlight the great potential of discovering statistically large numbers of HVSs of different spectral types in LAMOST survey data. This will ultimately enable us to achieve a better understanding of the nature of Galactic HVSs and their ejection mechanisms, and to constrain the structure of the Galaxy.

Case study of a school-based agriculture program and its impact on student learning and the school community
Creators: Faber, Jason Lee
Publisher: name: University of Alberta Library
Year: 2022

Rural schools in Alberta face unique challenges such as decreased funding linked to declining enrollment, obstacles in attracting and retaining teachers, and difficulty providing diverse programs. Despite such challenges, many rural schools have proven sustainable and resilient. Through innovative and creative responses, such as place-based pedagogy and community partnerships, there are examples of rural schools that have successfully navigated the trials inherent in rural education. This research project is a case study of a remote, rural Alberta school implementing a school-based agriculture program. Through community partnerships, New Haven Community School developed a school-based agriculture program to re-engage the community, increase student engagement and success, and develop career pathways for students.

Gamma rays and neutrinos from a cosmic ray source in the Galactic Center region
Creators: name: Supanitsky, A. D.
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The center of the our Galaxy is a region where very energetic phenomena take place. In particular powerful cosmic ray sources can be located in that region. The cosmic rays accelerated in these sources may interact with ambient protons and/or low energy photons producing gamma rays and neutrinos. The observation of these two types of secondary particles can be very useful for the identification of the cosmic ray sources and for the understanding of the physical processes occurring during acceleration. Motivated by the excess in the neutrino spectrum recently reported by the IceCube Collaboration, we study in detail the shape of the gamma ray and neutrino spectra originated from the interaction of cosmic ray protons with ambient protons for sources located in the Galactic Center region. We consider different models for proton acceleration and study the impact on the gamma ray and neutrino spectra. We also discuss the possibility to constrain and even identify a particular neutrino source by using the information given by the gamma ray spectrum taking advantage of the modification of the spectral shape, caused by the interaction of the gamma rays with the photons of the radiation field present in the interstellar medium, which strongly depends on the source distance.

description: Dieses Diskussionspapier beschäftigt sich mit der Frage, wie sich digitale Kompetenzen im Zuge der COVID-19-Pandemie verändert haben und welche Rückschlüsse daraus auf soziale Nachhaltigkeit gezogen werden können. Dabei werden verschiedene Konzepte zu digitalen Kompetenzen vorgestellt sowie die Resilienz, Selbstwirksamkeit und gesellschaftliche Teilhabe als Dimensionen sozialer Nachhaltigkeit eingeführt. Die Ergebnisse beruhen auf dem Datenmaterial der ersten drei Erhebungsphasen zwischen März und September 2020 des bürger- und sozialwissenschaftlichen Forschungsprojekts „Logbuch der Veränderungen“ der Hochschule für nachhaltige Entwicklung Eberswalde (HNEE). Dabei handelt es sich um eine Online-Tagebuchstudie, welche anhand der COVID-19- Pandemie gesellschaftlichen Wandel besser verstehen möchte. In dem vorliegenden Diskussionspapier wurde das Handlungsfeld „Information und Kommunikation“ mit knapp 650 Logbuch-Einträgen ausgewertet. Den theoretischen Rahmen bildet die Praxistheorie, welche gemeinsam geteilte soziale Praktiken ins Zentrum der Betrachtung stellt. Bei der Analyse des vielfältigen, qualitativen Datenmaterials wurden sechs veränderte Praktiken identifiziert: 1) „Informationsbeschaffung“, 2) „Virtuelle Kommunikation und Begegnung“, 3) „Digitales Arbeiten“, 4) „Freizeit und Unterhaltung“, 5) „Social-Media-Nutzung“ und 6) „Analoge Begegnungen“. Bei allen Praktiken gibt es das Bedürfnis nach Abgrenzung von der digitalen Nutzung bzw. teilweise wahrgenommenen Übernutzung. Dies bedarf neuer Kompetenzen, um diese Abgrenzung zu ermöglichen. Zudem wird ein Spannungsfeld zwischen den zahlreichen neuen Möglichkeiten und der Herausforderung, mit dieser neuen Vielfalt umzugehen, deutlich. Es kann von einer gewissen kulturellen Verzögerung bei der Anpassung an den (technischen) Wandel gesprochen werden. Zum Umgang damit braucht es einen gesellschaftlichen Diskurs, damit neue kulturelle Normen und soziale Regeln entwickelt werden können, mit dem Ziel, die negativen Auswirkungen der digitalen Praktiken zu reduzieren und die positiven Auswirkungen zu erkennen und nutzbar zu machen.

description: The working paper focuses on examining the practice of curating and exhibiting from a cultural studies perspective. The considerations in this paper are guided by relating Stuart Hall’s constructivist and post-structuralist work on representation theory, which has so far been widely received in media theory, to the field of exhibiting. Hall’s theoretical insight is significant because of its multidimensionality, as he comprehends the constitution of meaning and knowledge, considering not only the production practices, their mediality and materiality, but also the reception of media representations. The paper presents a tentative theoretical classification for understanding curating and exhibiting as practices of representation. Furthermore, it underscores the salience of this analytical perspective to reflect on educational exhibitions and the corresponding curatorial work, which seek to address socially significant issues and bring about political awareness.
description: Das Arbeitspapier widmet sich der Auseinandersetzung mit der Praxis des Kuratierens und des Ausstellens aus einer kulturwissenschaftlichen Perspektive. Geleitet werden die Überlegungen in diesem Papier davon, die konstruktivistisch und poststrukturalistisch begründete repräsentationstheoretische Arbeit von Stuart Hall, welche bisher insbesondere in der Medientheorie breite Rezeption erfährt, auf das Feld des Ausstellens zu beziehen. Überzeugend und anregend an Halls Theorie ist nicht zuletzt auch das Konzept der Mehrdimensionalität, mit der er die Konstitution von Bedeutung und Wissen erkundet und hierbei sowohl die Herstellungspraktiken wie ihre Medialität und Materialität als auch die Rezeption von medialen Darstellungen berücksichtigt. Das Papier stellt Markierungen einer theoretischen Einordnung des Kuratierens und Ausstellens als Repräsentationspraxis vor und nähert sich abschließend der Frage, inwiefern diese analytische Perspektive auch für die Reflexion des professionellen Handelns produktiv sein kann. Im Fokus der Betrachtungen stehen insbesondere Ausstellungen und in diesem Kontext die entsprechende kuratorische Arbeit, welche Vermittlung von gesellschaftlich bedeutsamen Themen zum Ziel haben und sich u.a. auch als bildungspädagogische Angebote verstehen.

description: In this survey paper, we will present a number of core algorithmic questions concerning several transitive reduction problems on network that have applications in network synthesis and analysis involving cellular processes. Our starting point will be the so-called minimum equivalent digraph problem, a classic computational problem in combinatorial algorithms. We will subsequently consider a few non-trivial extensions or generalizations of this problem motivated by applications in systems biology. We will then discuss the applications of these algorithmic methodologies in the context of three major biological research questions: synthesizing and simplifying signal transduction networks, analyzing disease networks, and measuring redundancy of biological networks.

description: The effects of commercial enzymes (pectinases, cellulases, beta-1-3-glucanases, and pectin lyases) on the recovery of anthocyanins and polyphenols from blackcurrant press cake were studied considering two solid:solvent ratios (1:10 and 1:4 w/v). β-glucanase enabled the recovery of the highest total phenolic content – 1142 mg/100 g, and the extraction of anthocyanins was similar using all enzymes (~400 mg/100 g). The use of cellulases and pectinases enhanced the extraction of antioxidants (DPPH − 1080 mg/100 g; CUPRAC – 3697 mg/100 g). The freeze-dried extracts presented antioxidant potential (CUPRAC, DPPH), which was associated with their biological effects in different systems: antiviral activity against both non-enveloped viruses (enterovirus coxsack-ievirus A-9) and enveloped coronaviruses (HCoV-OC43), and cytotoxicity towards cancer cells (A549 and HCT8). No cytotoxic effects on normal human lung fibroblast (IMR90) were observed, and no anti-inflammatory activity was detected in lipopolysaccharides-treated murine immortalised microglial cells.

description: The Capability Approach/Capability Theory (CA/T) makes the normative claim that freedom to achieve well-being is of primary moral importance. It has made significant contributions in its original field of Development Studies and has also been used in other fields as a framework to assess the relation between well-being and socio-economic contexts, to inform policies for social change. CA/T’s move from a focus only on resources (redistribution) reveals how the relation between the elements of participation and freedom in the achievement of well-being becomes contested. This paper will use two examples from empirical research conducted with disabled people, their personal assistants and care workers to explore how attention to participation, connection, and affiliation can further develop CA/T.
Exploring teacher stress: Impacts and implications of teacher stress during a pandemic
Creators: Truemner, Deana Kristin
Publisher: name: University of Alberta Library
Year: 2022

The globe has faced extraordinary challenges as a result of the COVID-19 pandemic since March of 2020. Teachers in K-12 education are negotiating new ground in terms of teaching methods, technology, and student and family requirements (including mental health needs), all while adhering to mandatory curriculum and testing and maintaining a sense of balance in their personal lives and health. Teachers are affected on both a professional and personal level by this new configuration of stressors in the workplace, including their relationships and overall health and wellbeing. Despite recommendations to use current resources, few studies have investigated how pandemic stressors have affected teachers' professional and personal health and well-being, as well as student learning. Teachers are responsible for curriculum implementation. This research inquires into the personal experiences of three Alberta certificated teachers in their professional roles during the COVID-19 pandemic. It highlights key themes and challenges participants and their students experienced due to systemic failures in providing adequate resources, training and support for education in Alberta during the crisis. Participants share their trials, victories and perspectives regarding their environment, schools and divisions navigated the complexities of teaching during pandemic conditions.

subject: FOS: Computer and information sciences

description: We investigate the phenomenon that "every monad is a linear state monad". We do this by studying a fully-complete state-passing translation from an impure call-by-value language to a new linear type theory: the enriched call-by-value calculus. The results are not specific to store, but can be applied to any computational effect expressible using algebraic operations, even to effects that are not usually thought of as stateful. There is a bijective correspondence between generic effects in the source language and state access operations in the enriched call-by-value calculus. From the perspective of categorical models, the enriched call-by-value calculus suggests a refinement of the traditional Kleisli models of effectful call-by-value languages. The new models can be understood as enriched adjunctions.

description: A new platform for fabricating polariton lasers operating at room temperature is introduced: nitride-based distributed Bragg reflectors epitaxially grown on patterned silicon substrates. The patterning allows for an enhanced strain relaxation thereby enabling to stack a large number of crack-free AlN/AlGaN pairs and achieve cavity quality factors of several thousands with a large spatial homogeneity. GaN and ZnO active regions are epitaxially grown thereon and the cavities are completed with top dielectric Bragg reflectors. The two structures display strong-coupling and polariton lasing at room temperature and constitute an intermediate step in the way towards integrated polariton devices.
Archaeology and the history of Port Essington
Creators: name: Allen, Frederick James
Publisher: name: The Australian National University
Year: 1969

description: This thesis is an investigation into the use of archaeology as a technique for widening the range of historical evidence in the recent past. It records the first professional excavations of a European site in Australia, Port Essington in the Northern Territory. Consequently chapters 2 - 5 are concerned with describing the excavations and architecture remaining at Port Essington, and the methods and results of the analysis of a body of artifacts of types which have not been rul adequately described (at least in archaeological terms) elsewhere. The main object of this protracted analysis is to take full advantage of the unique opportunities of the site which was occupied for only eleven years and which has remained largely undisturbed since, thus providing a closely dated context for the artifacts which were recovered. A second major area of enquiry in this section is the analysis of an Aboriginal assemblage of implements made from bottle glass obtained from the European settlement.The implications of this collection are several: 1. It is the archaeological reflection of the impact of the Europeans upon the indigenous people. 2.It supports a hypothesis that the reasons for the non-manufacture of stone implements in the coastal regions of Arnhem Land may simply be explained as one of environmental determinism rather than cultural preference. 3. It adds important new information for the discussion of glass artifacts found elsewhere in the world. The second section is a brief history of the settlement. Chapter 6 examines the reasons for the establishment of Port Essington and suggests that the commercial reasons suggested by previous historians may be less important than the political considerations behind the establishment. Chapters 7 and 8 relate the history of the settlement, chapter 8 introducing the archaeological data as historical evidence. Chapter 9 suggests that following the discussion in chapter 6, Port Essington might well be regarded as a success rather than the failure it is generally considered to have been. The final chapter discusses the value of archaeology as a research tool for the recent historical past.

description: We study the time evolution of Ginibre matrices whose elements undergo Brownian motion. The non-Hermitian character of the Ginibre ensemble binds the dynamics of eigenvalues to the evolution of eigenvectors in a non-trivial way, leading to a system of coupled nonlinear equations resembling those for turbulent systems. We formulate a mathematical framework allowing simultaneous description of the flow of eigenvalues and eigenvectors, and we unravel a hidden dynamics as a function of new complex variable, which in the standard description is treated as a regulator only. We solve the evolution equations for large matrices and demonstrate that the non-analytic behavior of the Green's functions is associated with a shock wave stemming from a Burgers-like equation describing correlations of eigenvectors. We conjecture that the hidden dynamics, that we observe for the Ginibre ensemble, is a general feature of non-Hermitian random matrix models and is relevant to related physical applications.

description: The thermoelectric properties of MoS2 armchair nanoribbons with different width are studied by using first-principles calculations and Boltzmann transport theory, where the relaxation time is predicted from deformation potential theory. Due to the dangling bonds at the armchair edge, there is obvious structure reconstruction of the nanoribbons which plays an important role in governing the electronic and transport properties. The investigated armchair nanoribbons are found to be semiconducting with indirect gaps, which exhibit interesting width-dependent oscillation behavior. The smaller gap of nanoribbon with width N = 4 leads to a much larger electrical conductivity at 300 K, which outweighs the relatively larger electronic thermal conductivity when compared with those of N = 5, 6. As a results, the room temperature ZT values can be optimized to 2.7 (p-type) and 2.0 (n-type), which significantly exceed the performance of most laboratory results reported in the literature.

In this paper we derive and solve the kinetic equation for an equilibrium configuration in presence of the dark energy, by considering the Newtonian regime, being the observed velocities of the galaxies inside a cluster largely smaller than the light velocity. Results. The presence of the dark energy in the gravitational equilibrium equation leads to wide regions in the $W_0-ρ_Λ$ diagram where the equilibrium solutions are not permitted, due to the prevalence of the effects of the dark energy on the gravity.

description: Recently, the {\it Belle} and {\it BABAR} Collaborations published the single-inclusive electron-positron annihilation data at the center of mass energies ($\sqrt{s}$) of $10.52$ GeV and $10.54$ GeV, respectively. These new data offer one the possibility to determine the nonperturbative initial conditions of fragmentation functions much more accurately. In our previous work \cite{Soleymaninia:2013cxa}, we extracted the fragmentation functions for $π^\pm$ and $K^\pm$ particles at next-to-leading order (NLO) including these new data, for the first time. These new data are in the regions of larger scaled-energy $z$ and lower $\sqrt{s}$. Our main purpose is to show that adding these new data in our analysis how much improve the fragmentation functions of $π^\pm$ and $K^\pm$ at NLO. We hope this analysis can obvious the effects of these recent data on FFs for whom is studying the behavior of light meson FFs. We also apply, for the first time, the extracted fragmentation functions to make our predictions for the scaled-energy distributions of $π^\pm$ and $K^\pm$ inclusively produced in polarized top quark decays at NLO.

Construction of points realizing the regular systems of Wolfgang Schmidt and Leonard Summerer

description: In a series of recent papers, W. M. Schmidt and L. Summerer developed a new theory by which they recover all major generic inequalities relating exponents of Diophantine approximation to a point in $\mathbb{R}^n$, and find new ones. Given a point in $\mathbb{R}^n$, they first show how most of its exponents of Diophantine approximation can be computed in terms of the successive minima of a parametric family of convex bodies attached to that point. Then they prove that these successive minima can in turn be approximated by a certain class of functions which they call $(n,γ)$-systems. In this way, they bring the whole problem to the study of these functions. To complete the theory, one would like to know if, conversely, given an $(n,γ)$-system, there exists a point in $\mathbb{R}^n$ whose associated family of convex bodies has successive minima which approximate that function. In the present paper, we show that this is true for a class of functions which they call regular systems.

description: There is an ongoing debate about how to test and operationalize self-control. This limited understanding is in large part due to a variety of different tests and measures used to assess self-control, as well as the lack of empirical studies examining the temporal dynamics during the exertion of self-control. In order to track changes that occur over the course of exposure to a self-control task, we investigate and compare behavioral, subjective, and physiological indicators during the exertion of self-control. Participants completed both a task requiring inhibitory control (Go/No-Go task) and a control task (two-choice task). Behavioral performance and pupil size were measured during the tasks. Subjective vitality was measured before and after the tasks. While pupil size and subjective vitality showed similar trajectories in the two tasks, behavioral performance decreased in the inhibitory control-demanding task, but not in the control task. However, behavioral, subjective, and physiological measures were not significantly correlated. These results suggest that there is a disconnect between different measures of self-control with high intra- and interindividual variability. Theoretical and methodological implications for self-control theory and future empirical work are discussed.

Metha-Ramanathan for ε and k-semistable Decorated Sheaves

description: This paper is devoted to generalizing the Mehta-Ramanathan restriction theorem to the case of ε-semistable and k-semistable decorated sheaves. After recalling the definition of decorated sheaves and their usual semistability we define the ε and k-(semi)stablility. We first prove the existence of a (unique) ε-maximal destabilizing subsheaf for decorated sheaves (Section 3.1). After some others preliminar results (such as the opennes condition for families of ε-semistable decorated sheaves) we finally prove, in Section 3.7, a restriction theorem for slope ε-semistable decorated sheaves. In Section 4 we reach the same results in the k-semistability case that we did in the ε-semistability, but only for decorated sheaves of rank less or equal than 3.

description: We investigate non-resonant Raman response for iron-based superconductors using the framework of an effective S4 model that was recently proposed to capture the essential electronic and magnetic properties of Iron based superconductors. We compute the momentum matrix elements and the resulting Raman vertices exactly for different polarization geometries and amazingly find that a simple coskxcosky superconducting gap function is in good agreement with experimental data measured in both iron-pnictides and iron-chalcogenides. The Raman peaks are also matched quantitatively with the measured superconducting gaps by other experimental techniques. The result strengthens the validity of the S4 model and the dominance of the s-wave pairing for iron-based superconductors.

description: We use the worldline formalism to derive integral representations for three classes of amplitudes in scalar field theory: (i) the scalar propagator exchanging N momenta with a scalar background field (ii) the "half-ladder" with N rungs in x - space (iii) the four-point ladder with N rungs in x - space as well as in (off-shell) momentum space. In each case we give a compact expression combining the N! Feynman diagrams contributing to the amplitude. As our main application, we reconsider the well-known case of two massive scalars interacting through the exchange of a massless scalar. Applying asymptotic estimates and a saddle-point approximation to the N-rung ladder plus crossed ladder diagrams, we derive a semi-analytic approximation formula for the lowest bound state mass in this model.

description: We report on the discovery of SN2014J in the nearby galaxy M82. Given its proximity, it offers the best opportunity to date to study a thermonuclear supernova over a wide range of the electromagnetic spectrum. The first set of optical, near-IR and mid-IR observations of SN2014J, orchestrated by the intermediate Palomar Transient Factory (iPTF), show that SN2014J is a spectroscopically normal Type Ia supernova, albeit exhibiting high-velocity features in its spectrum and heavily reddened by dust in the host galaxy. Our earliest detections start just hours after the fitted time of explosion. We use high-resolution optical spectroscopy to analyze the dense intervening material and do not detect any evolution in the resolved absorption features during the lightcurve rise. Similarly to other highly reddened Type Ia supernovae, a low value of total-to-selective extinction, Rv < 2, provides the best match to our observations. We also study pre-explosion optical and near-IR images from HST with special emphasis on the sources nearest to the SN location.

description: We invoke the estimates of the amplitudes of the velocity perturbations $f_R$ and $f_θ$ caused by the influence of a spiral density wave that have been obtained by us previously from three stellar samples. These include Galactic masers with measured VLBI trigonometric parallaxes and proper motions, OB2 stars, and Cepheids. From these data we have obtained new estimates of the spiral pattern speed in the Galaxy $Ω_p:$ $24.61\pm2.06$, $24.71\pm1.29$ and $25.98\pm1.37$~km s$^{-1}$ kpc$^{-1}$ from the samples of masers, OB2 stars, and Cepheids, respectively. The corotation radii for these three samples $R_{\rm cor}/R_0$ are $1.16\pm0.09$, $1.15\pm0.06$ and $1.09\pm0.06,$ suggesting that the corotation circle is located between the Sun and the Perseus arm segment.

Partial restoration of chiral symmetry in a confining string

description: We attempt to describe the interplay of confinement and chiral symmetry breaking in QCD by using the string model. We argue that in the quasi-abelian picture of confinement based on the condensation of magnetic monopoles and the dual Meissner effect, the worldsheet dynamics of the confining string can be effectively described by the $1+1$ dimensional massless electrodynamics, which is exactly soluble. The transverse plane distribution of the chromoelectric field stretched between the quark and antiquark sources can then be attributed to the fluctuations in the position of the string. The dependence of the chiral condensate in the string on the (chromo-)electric field can be evaluated analytically, and is determined by the chiral anomaly and the $θ$-vacuum structure. Therefore, our picture allows to predict the distribution of the chiral condensate in the plane transverse to the axis connecting the quark and antiquark. This prediction is compared to the lattice QCD results; a good agreement is found.
