Issues of Respect: Reflections of First Nations Students' Experiences in Postsecondary Anthropology Classrooms
Creators: name: Te Hennepe, Sheila
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: First Nations students discuss negative responses to participation in anthropolo­gy classes. After contextualizing anthropology courses in the undergraduate curriculum of the Native Indian Teacher Education Program at the University of British Columbia, in connection with Indian control of Indian education, this article explores those negative reactions. A first analytic procedure is the applica­tion of Agar's (1986) discussion of perspective and voice. The issue is identified as one of unreconciled claims to authority to describe and define First Nations is­ sues. The position is adopted in this article that the students speak with authority about their reactions, and speak with authority as well about First Nations issues. Some of the students' discussion is categorized and presented in a request to people in the discipline to engage in reflexive examination of underlying premises about authority in anthropological discourse in the broader context of respect. Respect is an issue both in the way research about First Nations peoples is con­ ducted and in the way those issues are presented to students.

description: Η παρούσα διατριβή έχει ως στόχο την ανάπτυξη μιας μεθοδολογίας για τη δημιουργία ενός πρότυπου συστήματος αξιολόγησης της προσφερόμενης ποιότητος των Δ.Σ. με γνώμονα την αόποψη του επιβάτη. Η μεθοδολογία αυτή επεκτέινεται επίσης και στη χρήση στατιστικών μοντέλων για τον υπολογισμό σύνθετων παραμέτρων και δεικτών ικανοποίησης του πελάτη. Με τον τρόπο αυτό αναδεικνύονται οι ποιοτικοί παράμετροι που έχουν τη μεγαλύτερη βαρύτητα στη συνολική εικόνατου συστήματος και άρα επιτυγχάνεται η ιεράρχηση των παρεμβάσεων στις οποίες θα πρέπει να προβεί ο φορέας, ενώ συγχρόνως δημιουργείται ένας μηχανισμός υπολογισμού των επιπτώσεων που θα έχουν οι πραγματοποιούμενες παρεμβάσεις
description: The present thesis aims at the development of a methodology for the development of an evaluation system for the public transport systems provided quality taking into consideration the passengers point of view. This methodology is also extended to the use of statistical models for the calculation of complex parameters and customer satisfaction indicators. Thus, the qualitative parameters that have the greatest importance in the whole system are formed and hence the interventions hierarchy the relative authorities must proceed to are achieved, while, at the same time, a calculation mechanism for the repercussions the realized interventions have is created

description: We discuss two methods to encode one qubit into six physical qubits. Each of our two examples corrects an arbitrary single-qubit error. Our first example is a degenerate six-qubit quantum error-correcting code. We explicitly provide the stabilizer generators, encoding circuit, codewords, logical Pauli operators, and logical CNOT operator for this code. We also show how to convert this code into a non-trivial subsystem code that saturates the subsystem Singleton bound. We then prove that a six-qubit code without entanglement assistance cannot simultaneously possess a Calderbank-Shor-Steane (CSS) stabilizer and correct an arbitrary single-qubit error. A corollary of this result is that the Steane seven-qubit code is the smallest single-error correcting CSS code. Our second example is the construction of a non-degenerate six-qubit CSS entanglement-assisted code. This code uses one bit of entanglement (an ebit) shared between the sender and the receiver and corrects an arbitrary single-qubit error. The code we obtain is globally equivalent to the Steane seven-qubit code and thus corrects an arbitrary error on the receiver's half of the ebit as well. We prove that this code is the smallest code with a CSS structure that uses only one ebit and corrects an arbitrary single-qubit error on the sender's side. We discuss the advantages and disadvantages for each of the two codes.

Superlattices with a fixed LSMO layer thickness of 20 unit cells (u.c.) and varying SRO layer thickness show a sudden drop in magnetization on cooling through temperature where both LSMO and SRO layers are ferromagnetic. This behavior suggests an antiferromagnetic coupling between the layers. In addition, the samples having thinner SRO layers (n \TEXTsymbol{

description: On the whole, 51 patients and 59 edentulous jaws were examined. During the examination the patients had a silicon bite-block containing a known dimension aluminium object. The width of the object was measured in the cross-sectional reformatted images. The measurements were carried out by means of compasses is the scale of the radiographis film. They were performed by two examiners who measured twice each. It was demostrated that slight breathing and swallowing movements affect the sharpness of the image which affects the measurement accuracy. The importance of personal examiner intervention was shown the rippen limit error for Denta-Scan was estimated at 0,2mm. The reformatted images are perpenticular to the plane designated by the curve drawn to the axial slice and not to the surface of alveolar crest

description: The electronic self-energy is studied for a two dimensional electron gas coupled to a spin-orbit Rashba field and interacting with dispersionless phonons. For the case of a momentum independent electron-phonon coupling (Holstein model) we solve numerically the self-consistent non-crossing approximation for the self-energy and calculate the electron mass enhancement $m^*/m$ and the spectral properties. We find that, even for nominal weak electron-phonon interaction, for strong spin-orbit couplings the electrons behave as effectively strongly coupled to the phonons. We interpret this result by a topological change of the Fermi surface occurring at sufficiently strong spin-orbit coupling, which induces a square-root divergence in the electronic density of states at low energies. We provide results for $m^*/m$ and for the density of states of the interacting electrons for several values of the electron filling and of the spin-orbit interaction.

description: Let n be a positive integer, and let A be a strongly commutative differential graded (DG) algebra over a commutative ring R. Assume that (a) B=A[X_1,...,X_n] is a polynomial extension of A, where X_1,...,X_n are variables of positive degrees; or (b) A is a divided power DG R-algebra and B=A is a free extension of A obtained by adjunction of variables X_1,...,X_n of positive degrees. In this paper, we study naive liftability of DG modules along the natural injection A-->B using the notions of diagonal ideals and homotopy limits. We prove that if N is a bounded below semifree DG B-module such that Ext_B^i(N, N)=0 for all i>0, then N is naively liftable to A. This implies that N is a direct summand of a DG B-module that is liftable to A. Also, the relation between naive liftability of DG modules and the Auslander-Reiten Conjecture has been described.

description: Exploring the physics and potential applications of vectorially structured light with propagation-invariant transverse structures has benefited many areas of modern optics and photonics. In this paper, we investigate the non-eigen vector modes of paraxial light fields, focusing on the propagation variations and revivals of their transverse structures, including both spatial and polarization structures. We show that the physical mechanism behind the variations and revivals of their transverse structure is linked to the evolution of the intramodal phases between the constituting spatial modes. Such evolution originates from fractional Gouy phases, or rather, Geometric-phase difference between spatial modes with different orders under a same unitary transformation. This underlying principle, provides a general guideline for shaping vectorially structured light with custom propagation-evolution properties, and may also inspire a wide variety of new applications based on structured light.

Παράλληλα διερευνήθηκαν ερωτήματα για τους τρόπους πρόσληψης, κατανόησης και αξιοποίησης του διδακτικού υλικού από τους μαθητές. Κύρια διαπίστωση της έρευνας είναι ότι το διδακτικό υλικό μπορεί να συμβάλλει στη συγκρότηση της έννοιας της γραμμικής συνάρτησης μόνο στο βαθμό που αποκτά κατάλληλη νοηματοδότηση στο πλαίσιο της διδασκαλίας των μαθηματικών
description: In this dissertation the role and constribution of manipulatives in the formation of the mathematical concept of linear function is explored. An experimental plan was developed and applied for the selection of data, which involved students attending the 4th and 6th grade of primary school in the area of Thessaloniki. Students were taught the concept of linear function with the use of various types of reaching materials(manipulatives, diagrams tables, word problems). Questions about the ways of conception, comprehension and using of the teaching materials by the students were explored in parallel. Main conclusion of the research in that the teaching materials may contribute to the formation of the linear function concept only to the extent that it attributes proper meaning in the context of proper teaching of mathematics

description: Social decision support systems are able to aggregate the local perspectives of a diverse group of individuals into a global social decision. This paper presents a multi-relational network ontology and grammar-based particle swarm algorithm capable of aggregating the decisions of millions of individuals. This framework supports a diverse problem space and a broad range of vote aggregation algorithms. These algorithms account for individual expertise and representation across different domains of the group problem space. Individuals are able to pose and categorize problems, generate potential solutions, choose trusted representatives, and vote for particular solutions. Ultimately, via a social decision making algorithm, the system aggregates all the individual votes into a single collective decision.

description: Large samples of experimentally produced graphene are polycrystalline. For the study of this material, it helps to have realistic computer samples that are also polycrystalline. A common approach to produce such samples in computer simulations is based on the method of Wooten, Winer, and Weaire, originally introduced for the simulation of amorphous silicon. We introduce an early rejection variation of their method, applied to graphene, which exploits the local nature of the structural changes to achieve a significant speed-up in the relaxation of the material, without compromising the dynamics. We test it on a 3,200 atoms sample, obtaining a speedup between one and two orders of magnitude. We also introduce a further variation called early decision specifically for relaxing large samples even faster and we test it on two samples of 10,024 and 20,000 atoms, obtaining a further speed-up of an order of magnitude. Furthermore, we provide a graphical manipulation tool to remove unwanted artifacts in a sample, such as bond crossings.

description: Experimental studies on single-molecule junctions are typically in need of a simple theoretical approach that can reproduce or be fitted to experimentally measured transport data. In this context, the single-level variant of the Landauer approach is most commonly used but methods based on Marcus theory are also gaining in popularity. Recently, a generalized theory unifying these two approaches has also been developed. In the present work, we extend this theory so that it includes entropic effects (which can be important when polar solvents are involved, but are likely minor for solid-state systems). We investigate the temperature-dependence of the electric current and compare it to the behavior predicted by the Landauer and the conventional Marcus theory. We argue that this generalized theory provides a simple yet effective framework for understanding charge transport through molecular junctions. Furthermore, we explore the role of the entropic effects in different transport regimes and suggest experimental criteria for detecting them in solvated molecular junctions. Lastly, in order to account for nuclear tunnelling effects, we also demonstrate how lifetime broadening can be introduced into the Marcus-Levich-Dogonadze-Jortner-type description of electron transport.

description: We discuss the first moments of the parity-even Generalized Parton Distributions (GPDs) in a nucleon, corresponding to six (generalized) vector form factors. We evaluate these fundamental properties of baryon structure at low energies, utilizing the methods of covariant Chiral Perturbation Theory in the baryon sector (BChPT). Our analysis is performed at leading-one-loop order in BChPT, predicting both the momentum and the quark-mass dependence for the three (generalized) isovector and (generalized) isoscalar form factors, which are currently under investigation in lattice QCD analyses of baryon structure. We also study the limit of vanishing four-momentum transfer where the GPD-moments reduce to the well known moments of Parton Distribution Functions (PDFs). For the isovector moment _{u-d} our BChPT calculation predicts a new mechanism for chiral curvature, connecting the high values for this moment typically found in lattice QCD studies for large quark masses with the smaller value known from phenomenology. Likewise, we analyze the quark-mass dependence of the isoscalar moments in the forward limit and extract the contribution of quarks to the total spin of the nucleon. We close with a first glance at the momentum dependence of the isoscalar C-form factor of the nucleon.

We initially discussed some features of the model to only then compute the corrections to the Bose-Einstein condensation. The calculations were done by computing the generating functional, from which we extract the thermodynamics parameters. We also obtained the Lifshitz scaling correction for the critical temperature $T_c$ that sets the Bose-Einstein Condensation.

Προτείνεται ένα μαθηματικό μοντέλο για την κίνηση κύλισης παραμορφώσιμων ακροδακτύλων το οποίο βασίζεται σε πειραματικά δεδομένα της απόστασης κύλισης για μια πλειάδα παραμορφώσιμων υλικών. Γίνεται η κινηματική και δυναμική ανάλυση του συστήματος "ρομποτικά δάκτυλα-αντικείμενο". Εξάγονται οι δυναμικές εξισώσεις του συστήματος συμπεριλαμβάνοντας και τους περιορισμούς κύλισης των ακροδακτύλων. Μελετάται η κατάσταση ισορροπίας του συστήματος των ακροδακτύλων με το αντικείμενο η οποία εξερτάται από την παραμόρφωση και το είδος του υλικού που χρησιμοποιείται στα ακροδάκτυλα. Στη διατριβή παρουσιάζονται απλοί νόμοι ελέγχου για την ευσταθή λαβή του χειρισμού ενός αντικειμένου με παράλληλες πλευρές επαφών. Ο έλεγχος δεν προϋποθέτει την λύση των κινηματικών εξισώσεων του συστήματος για τη σχεδίαση της τροχιάς των δακτύλων, ούτε εξερτάται από την πλήρη γνώση των δυναμικών παραμέτρων του.

description: We show how to apply the scaling theory in an inhomogeneous system like harmonically trapped Bose condensate at finite temperatures. We calculate the temperature dependence of the critical number of particles by a scaling theory within the Hartree-Fock approximation and find that there is a dramatic increase in the critical number of particles as the condensation point is approached.

description: Maintaining security and privacy in real-world enterprise networks is becoming more and more challenging. Cyber actors are increasingly employing previously unreported and state-of-the-art techniques to break into corporate networks. To develop novel and effective methods to thwart these sophisticated cyberattacks, we need datasets that reflect real-world enterprise scenarios to a high degree of accuracy. However, precious few such datasets are publicly available. Researchers still predominantly use the decade-old KDD datasets, however, studies showed that these datasets do not adequately reflect modern attacks like Advanced Persistent Threats(APT). In this work, we analyze the usefulness of the recently introduced DARPA Operationally Transparent Cyber (OpTC) dataset in this regard. We describe the content of the dataset in detail and present a qualitative analysis. We show that the OpTC dataset is an excellent candidate for advanced cyber threat detection research while also highlighting its limitations. Additionally, we propose several research directions where this dataset can be useful.

description: In this work, we explore the possibility of using synthetically generated data for video-based gesture recognition with large pre-trained models. We consider whether these models have sufficiently robust and expressive representation spaces to enable "training-free" classification. Specifically, we utilize various state-of-the-art video encoders to extract features for use in k-nearest neighbors classification, where the training data points are derived from synthetic videos only. We compare these results with another training-free approach -- zero-shot classification using text descriptions of each gesture. In our experiments with the RoCoG-v2 dataset, we find that using synthetic training videos yields significantly lower classification accuracy on real test videos compared to using a relatively small number of real training videos. We also observe that video backbones that were fine-tuned on classification tasks serve as superior feature extractors, and that the choice of fine-tuning data has a substantial impact on k-nearest neighbors performance. Lastly, we find that zero-shot text-based classification performs poorly on the gesture recognition task, as gestures are not easily described through natural language.

Low emission zones: Effects on alternative-fuel vehicle uptake and fleet CO2 emissions

description: This study analyses the actual effect of a representative low-emission zone (LEZ) in terms of shifting vehicle registrations towards alternative fuel technologies and its effectiveness for reducing vehicle fleet CO2 emissions. Vehicle registration data is combined with real life fuel consumption values on individual vehicle model level, and the impact of the LEZ is then determined via an econometric approach. The increase in alternative fuel vehicles (AFV) registration shares due to the LEZ is found to be significant but fosters rather fossil fuel powered AFV and plug-in hybrid electric vehicles than zero emission vehicles. This is reflected in the average CO2 emissions of newly registered vehicles, which do not decrease significantly. In consequence, while the LEZ is an effective measure for stimulating the shift towards low emission vehicles, the support of non-electric AFV as low emission vehicles jeopardizes its effectiveness for decarbonizing the vehicle fleet.

description: We investigate nongeminate recombination in organic solar cells based on copper phthalocyanine (CuPc) and C$_{60}$. Two device architectures, the planar heterojunction (PHJ) and the bulk heterojunction (BHJ), are directly compared in view of differences in charge carrier decay dynamics. We apply a combination of transient photovoltage (TPV) experiments, yielding the small perturbation charge carrier lifetime, and charge extraction measurements, providing the charge carrier density. In organic solar cells, charge photogeneration and recombination primarily occur at the donor--acceptor heterointerface. Whereas the BHJ can often be approximated by an effective medium due to rather small scale phase separation, the PHJ has a well defined two-dimensional heterointerface. To study recombination dynamics in PHJ devices most relevant is the charge accumulation at this interface. As from extraction techniques only the spatially averaged carrier concentration can be determined, we derive the charge carrier density at the interface $n_{int}$ from the open circuit voltage. Comparing the experimental results with macroscopic device simulation we discuss the differences of recombination and charge carrier densities in CuPc:C$_{60}$ PHJ and BHJ devices with respect to the device performance. The open circuit voltage of BHJ is larger than for PHJ at low light intensities, but at 0.3 sun the situation is reversed: here, the PHJ can finally take advantage of its generally longer charge carrier lifetimes, as the active recombination region is smaller.

description: Sufficient conditions for the similarity of the operator $A := 1/r(x) (-d^2/dx^2 +q(x))$ with an indefinite weight $r(x)=(\sgn x)|r(x)|$ are obtained. These conditions are formulated in terms of Titchmarsh-Weyl $m$-coefficients. Sufficient conditions for the regularity of the critical points 0 and $\infty$ of $J$-nonnegative Sturm-Liouville operators are also obtained. This result is exploited to prove the regularity of 0 for various classes of Sturm-Liouville operators. This implies the similarity of the considered operators to self-adjoint ones. In particular, in the case $r(x)=\sgn x$ and $q\in L^1(R, (1+|x|)dx)$, we prove that $A$ is similar to a self-adjoint operator if and only if $A$ is $J$-nonnegative. The latter condition on $q$ is sharp, i.e., we construct $q\in \cap_{γ<1} L^1(R, (1+|x|)^γdx)$ such that $A$ is $J$-nonnegative with the singular critical point 0. Hence $A$ is not similar to a self-adjoint operator. For periodic and infinite-zone potentials, we show that $J$-positivity is sufficient for the similarity of $A$ to a self-adjoint operator. In the case $q\equiv 0$, we prove the regularity of the critical point 0 for a wide class of weights $r$. This yields new results for "forward-backward" diffusion equations.

description: Previously, the Einstein equation has been described as an equation of state, general relativity as the equilibrium state of gravity, and $f({\cal R})$ gravity as a non-equilibrium one. We apply Eckart's first order thermodynamics to the effective dissipative fluid describing scalar-tensor gravity. Surprisingly, we obtain simple expressions for the effective heat flux, "temperature of gravity", shear and bulk viscosity, and entropy density, plus a generalized Fourier law in a consistent Eckart thermodynamical picture. Well-defined notions of temperature and approach to equilibrium, missing in the current thermodynamics of spacetime scenarios, naturally emerge.

 historical time in Guy Debord and Robert Kurz-Roswitha Scholz. 201 f. (Doctoral Thesis).

 Janeiro. Rio de Janeiro-RJ, 2017.
 This thesis aims to analyze the subject of historical time implicit in the theory of the spectacle,
 by means of the theory of crisis related to the theory of value-dissociation. Such an endeavor
 relied especially upon chapters V and VI from Guy Debord’s “The society of the spectacle”
 (1967) (but also, to a certain extent, made use of pre-situationist, situationist, and postsituationist
 works), carrying out a study of time and history registered in some of his most
 remarkable influences, such as Marx, Hegel, Feuerbach, and Lukács, following a critique of
 commodity fetishism. It is understood that in a non-orthodox fashion composed for a
 Debordian explanation of historical time contributed to a critique of social time much too
 distant from Marx’s époque, although situated under the specificity of fetish-capital. The
 critique of spectacular time, highlighted by the situationists themselves, firstly was activated
 with a views to surpassing art, which led to the critique of the spectacle per se, right in the
 middle of the interval of the Situationist International operations (1957-1972). The purpose of
 this articulation was found in a Kurzian assumption that the 20th century presented a higher
 level of historical alienation, that is, the spectacular alienation, peaking in what he called
 ‘collapse of modernity’. Provided that, together with Scholz, his body of theory (also thought
 within the contribution of Moishe Postone and Alfred Sohn-Rethel) worked herein as a causa
 movens for the situationist view of time, his own understanding of social time was asserted as
 well. Thus, the motif was not understood since what a theory could enable another in what
 could be said, but rather within what could be said regards to the immanence of the time
 subject related to both bodies of theory. Firstly, the inquiry unfolded from what could be
 referred to as historical time of capital, so that afterwards an analytical typification of the
 spectacular time of obsolescence and a time of the collapse of modernity could be structured
 independently; both of them potentially operating as an introductory study of the historical
 obsolescence of the commodity and of capital, in its sociotemporal dimension.
 Key words: Time; History; Spectacle; Crisis; Collapse of modernity.
A Conserved epitope on the surface of carlaviruses
Creators: name: Wieczorek, Andrew A.
Publisher: name: University of British Columbia
Year: 2008

description: The seed certification program in British Columbia relies heavily on double antibody sandwich-enzyme-linked immunosorbent assays (DAS-ELISA) for detection of plant pathogens. Each individual sample requires a separate test for each pathogen. The aim of this research was to simplify the procedure, which would result in considerable savings in both cost and labour. A method to facilitate the testing by allowing several individual samples to be evaluated in a single trial was developed by finding a unique antibody that could be used for the detection of several viruses. A monoclonal antibody was raised to the coat protein of potato virus M which also reacted to other members of the carlavirus group. Viruses morphologically similar to carlaviruses but belonging to the potyvirus and potexvirus groups were also challenged with the PVM antibody, but failed to react, despite evidence of conserved amino acid sequences in the coat proteins of carlaviruses and potexvirus. A variety of host species infected with viruses from all three groups were also tested to eliminate the possibility of a reaction by the antibody to a plant component. Partial characterization of the epitope to which the antibody reacts was also accomplished. It is postulated that the epitope is conformational in nature, since the antibody fails to detect coat protein subunits in Western blots, and does not react to virus degraded by long-term storage either in purified form or in tissue. Since the epitope readily reacts in DAS-ELISA, it was concluded that the antigenic site must be located on the surface of the virus particle. This is the first demonstration of an epitope that shows broad specificity within a virus group which is located on the surface of the virus rather than buried in the viral core. The utilization of this epitope for diagnostic purposes is discussed.
