description: The primary aim of this study was to extend existing theory on the relationship between chance-level performance and the number of alternatives and trials in closed-set, forced-choice speech audiometry and sound localization methods. When calculating chance performance for closed-set, forced-choice experiments with multiple trials, the binomial distribution should be preferred over the simple 1/a probability, as the latter is appropriate only for single trial experiments. The historical use of constant hit rates for determining chance performance has been based upon the assumption that random hits are distributed evenly across multiple trials. For any closed-set, forced-choice task with 2 to 10 alternatives and 2 to 100 trials, we calculated the probability of obtaining any given hit rate due to random guessing alone according to the binomial distribution. Hit rates with probabilities p > 0.05 were interpreted as being likely to occur due to random chance alone, whereas hit rates with probabilities of p <= 0.05 were interpreted as being unlikely to occur due to chance alone. For sound localization experiments with speakers at fixed positions, the expected probability of a random hit was also calculated using the binomial distribution. The expected angular root mean square (rms) error in sound localization resulting from the random selection of sound sources was investigated using Monte Carlo simulations. A new aspect in the interpretation of test results was identified for situations in which the observed number of hits is much lower than would be expected due to chance alone. For test methods incorporating a relatively low number of alternatives and a sufficiently high, yet clinically feasible, number of trials, both upper and lower thresholds for chance-level performance could be identified. This lower threshold represents the lowest hit rate which can be expected through random chance alone. Extending interpretation of results to include this lower threshold affords the ability to not only identify performance significantly superior to that of chance, but also that significantly poorer than chance and thereby represents a simple method for the objective detection of malingering.

Novice and experienced science teachers' perspectives on theory and practice : a shift toward integrating everyday and academic concepts
Creators: name: O'Reilly, Tara-Lynn
Publisher: name: University of British Columbia
Year: 2015

description: The current research used a Vygotskian approach, in particular his definitions of everyday and academic concepts, to examine the perspectives of two novice and two experienced science teachers on the relationship between theory and practice. Semi-structured and artefact-mediated interviews were used to examine novice and experienced science teachers’ definitions of theory, practice, and learning, as well as their experiences in teacher education, and their expectations for their future pedagogy. Thematic analysis was conducted to analyze and interpret the interviews and the artefacts produced. There were five findings that emerged from the research: different perspectives on theory and its role in decision-making processes; a shift in perspective on teaching practice, student practice, and learning; the importance of gaining teaching experience—and further education—in the development of effective teaching; how the role a teacher candidate plays, as a student or a teacher, affects their learning and identity construction and; the importance of the relationships between the university and the practicum school. There were eight barriers that appeared to affect teacher candidate learning and development that were identified in the research and eight recommendations were articulated to overcome these barriers. Three of the recommendations included: for teacher education programs to examine ways to make theory explicit and to discuss how to apply theory and practice; to develop assessments that assess teacher candidates’ understanding of theory and their ability to apply theory in practice; to increase time for guided dialogue and reflection around why certain strategies are used in different contexts and/or for different students and how theoretical grounding can help teachers think about approaching classroom interactions. Working toward the integration of everyday and academic concepts in teacher education may enable the development of theory and practice as related academic concepts, thus, improving their internalization as psychological tools that facilitate learning and development in classroom contexts.

description: We have measured the half-life of the beta decay of 198Au to be 2.6948(9) d, with the nuclide sited in an insulating environment. Comparing this result with the half-life we measured previously with a metallic environment, we find the half-lives in both environments to be the same within 0.04%, thus contradicting a prediction that screening from a "plasma" of quasi-free electrons in a metal increases the half-life by as much as 7%.

description: Plasma membranes appear as deformable systems wherein molecules are free to move and diffuse giving rise to condensed microdomains (composed of ordered lipids, transmembrane proteins and cholesterol) surrounded by disordered lipid molecules. Such denser and thicker regions, namely lipid rafts, are important communication hubs for cells. Indeed, recent experiments revealed how the most of active signaling proteins co-localize on such domains, thereby intensifying the biochemical trafficking of substances. From a material standpoint, it is reasonable to assume the bilayer as a visco-elastic body accounting for both in-plane fluidity and elasticity. Consequently, lipid rafts contribute to membrane heterogeneity by typically exhibiting higher stiffness and viscosity and by locally altering the bilayer dynamics and proteins activity. A chemo-mechanical model of lipid bilayer coupled with interspecific dynamics among the resident species (typically transmembrane receptors and trasporters) has been recently formulated to explain and predict how proteins regulate the dynamic heterogeneity of membrane. However, the explicit inclusion of the membrane viscosity in the model was not considered. To this aim, the present work enriches the constitutive description of the bilayer by modeling its visco-elastic behavior. This is done through a strain-level dependent viscosity able to theoretically trace back the alteration of membrane fluidity experimentally observed in lipid phase transitions. This provides new insights into how the quasi-solid and fluid components of lipid membrane response interact with the evolution of resident proteins by affecting the activity of raft domains, with effects on cell mechano-signaling.

description: Context: Warps occurring in galactic discs have been studied extensively in HI and in the optical, but rarely in the near-infrared (NIR) bands that trace the older stellar populations. Aims: We provide NIR data of nearby edge-on galaxies, combined with optical observations, for direct comparison of the properties of galactic warps as a function of wavelength, and calculate warp curves for each galaxy and obtain the characteristic warp parameters. We discuss these properties as possible constraints to the different mechanisms that have been proposed for the development and persistence of galactic warps. Methods: We observed 20 galaxies that were selected from a statistically complete diameter-limited subsample of edge-on disc galaxies. We used the Cerro Tololo Infrared Imager (CIRIM) at the CTIO 1.5m Ritchey-Chretien telescope to acquire the NIR data. We used the 1.54m Danish and 0.92m Dutch telescopes at the European Southern Observatory's La Silla site for our optical observations. Results: Our results show that 13 of our 20 sample galaxies are warped, with the warp more pronounced in the optical than at NIR wavelengths. In the remaining seven galaxies, no warp is apparent within the limitations of our automated detection method. The transition between the unperturbed inner disc and the outer, warped region is rather abrupt. S0 galaxies exhibit very small or no warps. The magnetic model remains one of a number of interesting formation scenarios.

Do positive memories change over time? : an examination of memory and social anxiety
Creators: name: Glazier, Brianne
Publisher: name: University of British Columbia
Year: 2015

description: Cognitive theorists suggest that individuals with social anxiety disorder (SAD) display negative memory biases when recalling social events. However, evidence for memory bias has proved elusive. This study builds on recent work on post-event processing of negative events and extends this research to investigate whether positive memories change over time. Undergraduate participants engaged in an unexpected speech task with free choice of topic. After rating their own performance, participants were randomly assigned to receive either positive or neutral feedback. Following a distractor task, participants reported their memory of the feedback they received and completed brief measures of mood and affect. One week later, participants rated their memory of the session one feedback, indicated the amount of post-event processing they engaged in during the week, and completed symptom measures. Results indicated a significant interaction between social anxiety and condition predicting change in memory valence. This relationship was not mediated by post-event processing. This study provides evidence for biased memory of social performance feedback among socially anxious individuals.

description: High-quality Pr0.7Ca0.3MnO3/SrRuO3 superlattices were fabricated by pulsed laser deposition and were investigated by high-resolution transmission electron microscopy and SQUID magnetometry. Superlattices with orthorhombic and tetragonal SrRuO3 layers were investigated. The superlattices grew coherently; in the growth direction Pr0.7Ca0.3MnO3 layers were terminated by MnO2- and SrRuO3 layers by RuO2-planes. All superlattices showed antiferromagnetic interlayer coupling in low magnetic fields. The coupling strength was significantly higher for orthorhombic than for tetragonal symmetry of the SrRuO3 layers. The strong interlayer exchange coupling in the superlattice with orthorhombic SrRuO3 layers led to a magnetization reversal mechanism with a partially inverted hysteresis loop.

Understanding weight restoration in adolescent anorexia as a parent project
Creators: name: Socholotiuk, Krista Deanne
Publisher: name: University of British Columbia
Year: 2015

description: Parent-led weight restoration is a key intervention of family-based treatment, an empirically-supported approach for the treatment of adolescent anorexia. Little is known about the processes by which parents implement weight restoration, and current understandings of this intervention are primarily informed by professional perspectives. The aim of this study was to increase knowledge and understanding of parent-led weight restoration by examining parents’ actions while engaged in efforts to help their adolescent recover weight. The guiding research question was, “How do parents participate in the weight restoration of their adolescent as he or she recovers from anorexia?” This multicase study (Stake, 2006) used the action project method (Young, Valach, & Domene, 2005) and conceptual framework of contextual action theory (Valach, Young & Lynam, 2002) to examine five cases of parents engaged in actions intended to help their adolescent recover weight and to alter eating disorder behaviours. Data were collected using multi-part interviews, and analyzed according to the action project method and the multicase approach. Qualitative analysis revealed parents’ treatment-related goals of adolescent weight recovery were situated in a larger system of projects and careers in the parents’ personal and family lives. Conceptualizing the parents’ actions within this system revealed personally and socially meaningful weight restoration projects, and the relational and social meaning of these projects was found to motivate and steer parents’ day-to-day weight restoration actions. Some common joint projects emerged across the cases, such as seeking support and partnership and managing burden and distress associated with tension between weight restoration and other personal and parenting projects, especially adolescent development and parent identity processes. Implications for counselling practice with parents implementing weight restoration treatments are drawn.

description: We consider a classical system of two-dimensional (2D) charged particles, which interact through a repulsive Yukawa potential $exp(-r/λ)/r$, confined in a parabolic channel which limits the motion of the particles in the $y$-direction. Along the $x$-direction, the particles are also subject to a periodic potential substrate. The ground state configurations and the normal mode spectra of the system are obtained as function of the periodicity and strength of the periodic potential ($V_0$), and density. An interesting set of tunable ground state configurations are found, with first and second order structural transitions between them. A magic configuration with particles aligned in each minimum of the periodic potential is obtained for V_0 larger than some critical value which has a power law dependence on the density. The phonon spectrum of different configurations were also calculated. A localization of the modes into a small frequency interval is observed for a sufficient strength of the periodic potential. A tunable band-gap is found as a function of $V_0$. This model system can be viewed as a generalization of the Frenkel and Kontorova model.

Advances in Atmospheric Sciences is intensely interrelated with international peer journals in terms of similar citing pattern. However, there is still room for an increase in its academic visibility given the comparatively smaller reception in terms of cited references.

description: We derive a general formalism for evaluating the high-frequency limit of the thermoelectric power of strongly correlated materials, which can be straightforwardly implemented in available first principles LDA+DMFT programs. We explore this formalism using model Hamiltonians and we investigate the validity of approximating the static thermoelectric power $S_0$, by its high-temperature limit, $S^*$. We point out that the behaviors of $S^*$ and $S_0$ are qualitatively different for a correlated Fermi liquid near the Mott transition, when the temperature is in the coherent regime. When the temperature is well above the coherent regime, e.g., when the transport is dominated by incoherent excitations, $S^*$ provides a good estimation of $S_0$.

Title: Analysis of In-vehicle Black Carbon Exposure and Trip Characteristics Using GPS Logs and Diaries

Abstract:

Background: Global Positioning Systems (GPS) are being used more frequently in health research. To limit respondent burden, and because of technical problems with the development of miniaturized air quality sensors; exposure is determined afterwards by linking GPS traces with air pollution models or nearby monitoring stations. In-vehicle exposure may however be not only related to yearly averaged outdoor concentrations. Objectives: To investigate whether the levels of in-vehicle Black Carbon (BC) concentrations are influenced by trip duration, hour of the day, traffic intensities, and spatial parameters like degree of urbanization or road type. Methods: Personal exposure measurements were done using µ-aethalometers, trip diaries and GPS devices. More than 1000 car-trips were evaluated in Flanders, Belgium. GPS coordinates were assigned to road segments to allow BC concentrations to be linked with trip and road characteristics. Results: Due to loss of signal, technical issues or participant’s error, 30% of all car trips had no GPS coordinates. If the distance between a GPS point and the closest road with known traffic intensities was larger than 30m, the observation was omitted (23% of all recorded coordinates). Average BC concentrations on highways are comparable to concentrations on urban roads (8.3 µg/m3), but almost double the concentrations on rural roads (4.7 µg/m3). BC concentrations are elevated at lower speeds (<30 km/h) and at speeds above 80 km/h. Driving on roads with low instantaneous traffic intensities resulted in lower exposures than driving on roads with higher traffic intensities. Concentrations on traffic peak hours are higher compared to off-peak hours. We found no evidence of a buildup of BC particles inside a vehicle; but there is a link between trip length and use of certain road types. Conclusions: We found evidence that BC concentrations in vehicles depend on speed, timing of the trip, degree of urbanization, and traffic intensities.
Massive runaway stars in the Large Magellanic Cloud

description: The origin of massive field stars in the Large Magellanic Cloud (LMC) has long been an enigma. The recent measurements of large offsets (~100 km/s) between the heliocentric radial velocities of some very massive (O2-type) field stars and the systemic LMC velocity provides a possible explanation of this enigma and suggests that the field stars are runaway stars ejected from their birth places at the very beginning of their parent cluster's dynamical evolution. A straightforward way to prove this explanation is to measure the proper motions of the field stars and to show that they are moving away from one of the nearby star clusters or OB associations. This approach however is complicated by the large distance to the LMC, which makes accurate proper motion measurements difficult. We use an alternative approach for solving the problem, based on the search for bow shocks produced by runaway stars. The geometry of detected bow shocks would allow us to infer the direction of stellar motion and thereby to determine their possible parent clusters. In this paper we present the results of a search for bow shocks around six massive field stars which were suggested in the literature as candidate runaway stars. Using archival (Spitzer Space Telescope) data, we found a bow shock associated with one of our program stars, the O2 V((f*)) star BI 237, which is the first-ever detection of bow shocks in the LMC. Orientation of the bow shock suggests that BI 237 was ejected from the OB association LH 82 (located at ~120 pc in projection from the star). A by-product of our search is the detection of bow shocks generated by four OB stars in the field of the LMC and an arc-like structure attached to the candidate luminous blue variable R81 (HD 269128). The geometry of two of these bow shocks is consistent with the possibility that their associated stars were ejected from the 30 Doradus star forming complex.

description: The overall objective of LEA is to “speed up” knowledge transfer, dialogue and awareness raising of innovative procurement. One of the key objectives of the LEA project is to strengthen the dialogue between the demand and supply stakeholders of the Learntech procurement process. The purpose of WP4 is to support this objective by developing trainings and capacity building across various formats - including seminars, webinars, labs and think tank events - with a focus on accelerating knowledge exchange between the demand- and supply-side of the learntech market.

The overall objective of increasing knowledge exchange and dialogue between demand- and supply-side stakeholders is to inform the development of demand-based and cost-effective future learning environments. This dialogue has been accelerated in four main ways to ensure that suppliers have a good knowledge of the end users´ demands:

Open dialogues between the demand- and supply-side are fundamental for the success of the preparatory activities for launching an innovative procurement call and for the procurement process itself (after the awarding phase). In addition, involvement of end-users is deemed necessary for the success of the research and innovation activities. LEA will devote huge efforts in designing and implementing opportunities for concrete and constructive industry dialogues, where procurers, suppliers, researchers, end-users and other interested stakeholders will find the tools and the opportunity to be part of the process of shaping the challenges and needs and the visions for the future in education and learning technology.

description: The current industry standard for cybersecurity is risk mitigation, which is the identification, evaluation, and categorization of threats that are posed to an organization's network. The goal is to prevent attacks and if an organization is attacked popular standard is to react and remedy the attack. This form of cyber defense isn’t very reassuring to an organization and its users, once an attack is executed based on a study conducted by Booz Allen the average time an advanced persistent threat (APT) dwells on a victims’ network before it’s discovered is 200-250 days. That’s plenty of time for a malicious third party to extract valuable and personal data from an organization's network on its users and the organization. To prevent vulnerabilities like this organizations, need to reevaluate their network security methods and a newly proposed method of cyber defense is a cyber offense. Cyber Offense as a defense is already seen in some organizations but not widely accepted, these forms of offense can include but aren’t limited to threat hunting, red teaming, and ethical hacking.

description: An incomplete sky coverage poses difficulties in the extraction of the weak lensing information from the CMB. We test the reconstruction of the weak lensing convergence from CMB maps to which masks of point sources have been applied. We use the quadratic estimator with a kernel with finite support acting in real space for a Planck simulation. We recover the lensing signal without significant loss of power or addition of spurious correlations, thus showing that masking defected pixels does not affect the reconstruction of the weak lensing convergence in real space.

description: We study the structure of electromagnetic field of slowly rotating magnetized star in a Randall-Sundrum II type braneworld. The star is modeled as a sphere consisting of perfect highly magnetized fluid with infinite conductivity and frozen-in dipolar magnetic field. Maxwell's equations for the external magnetic field of the star in the braneworld are analytically solved in approximation of small distance from the surface of the star. We have also found numerical solution for the electric field outside the rotating magnetized neutron star in the braneworld in dependence on brane tension. The influence of brane tension on the electromagnetic energy losses of the rotating magnetized star is underlined. Obtained "brane" corrections are shown to be relevant and have non-negligible values. In comparison with astrophysical observations on pulsars spindown data they may provide an evidence for the brane tension and, thus, serve as a test for the braneworld model of the Universe.

In close proximity to the antiferromagnetic phase transition in BaFe$_2$As$_2$, a crossover to three dimensional critical behavior is anticipated and has been preliminarily observed. Here we report complementary measurements of two-dimensional magnetic fluctuations over a broad temperature range about T$_N$. The potential role of two-dimensional critical fluctuations in the magnetic phase behavior of BaFe$_2$As$_2$ and their evolution near the anticipated crossover to three dimensional critical behavior and long-range order are discussed.

Of particular interest is the timing of "peak water," when the reduction in ice area associated with retreat begins to offset the increased rate of climatic warming-induced melt. This study examines streamflow variability downstream of Bridge Glacier, in the southern Coast Mountains of BC. The glacier currently calves into a proglacial lake, and has been retreating rapidly since 1991, when the terminus retreated into an over-deepened basin. Despite the glacier's areal decrease from 92 km² in the early 1990s to 81 km² in 2014, interannual climatic variability has obscured any resulting reductions in late-summer streamflow. The objective of this study was to diagnose trends in streamflow, as associated with the accelerating retreat of a lake-calving glacier, examining the role of calving and retreat on the magnitude and timing of summer streamflow, as well as the persistence of icebergs in the basin. Snow melt, ice melt, and rainfall-runoff were estimated using a semi-distributed hydrological model, with glacier area determined from Landsat imagery. Two seasonal discharge trends were observed, an increase in winter flow attributed to ice discharge into the lake, and a decrease in late-summer flow attributed to decreasing glacier area behind the grounding line. Decreasing streamflow trends suggested that the glacier has passed peak water, and that streamflow will continue declining with reducing glacier area. Surface and subaqueous iceberg melt were computed using an energy-balance approach, assuming that net radiation received by the ice-proximal basin was consumed by subaqueous melt and heating of 0⁰C melt water. Fractional iceberg cover in the proximal basin was determined by spectral unmixing of Landsat imagery. Estimated melt volumes suggested that in the absence of large calving events, icebergs persist for roughly a year, with high fractional iceberg cover allowing for persistence into a second year. The results from this study contribute to our understanding of streamflow response for retreating valley glaciers, many of which will likely experience a transient lake-terminating phase as the terminus retreats into over-deepened basins.

description: While being one of the most popular question types, simple questions such as "Who is the author of Cinderella?", are still not completely solved. Surprisingly, even the most powerful modern Large Language Models are prone to errors when dealing with such questions, especially when dealing with rare entities. At the same time, as an answer may be one hop away from the question entity, one can try to develop a method that uses structured knowledge graphs (KGs) to answer such questions. In this paper, we introduce Konstruktor - an efficient and robust approach that breaks down the problem into three steps: (i) entity extraction and entity linking, (ii) relation prediction, and (iii) querying the knowledge graph. Our approach integrates language models and knowledge graphs, exploiting the power of the former and the interpretability of the latter. We experiment with two named entity recognition and entity linking methods and several relation detection techniques. We show that for relation detection, the most challenging step of the workflow, a combination of relation classification/generation and ranking outperforms other methods. We report Konstruktor's strong results on four datasets.

Community as client : an investigation of what helps and what hinders the integration of social justice into counselling practice

description: The purpose of this study is to shed light on the factors that promote or detract from the integration of social justice (SJ) into counselling practice. Research shows that psychological well-being is contingent on the presence of SJ (Prilleltensky, 1999; 2012), therefore, it must be a priority in the practice of counselling psychology. Over the past ten years there has been an increasing amount of literature written about the importance of integrating SJ into counselling practice (Lewis, 2011), but there appears to be a gap in applied research that explores the factors that promote or detract from successfully integrating SJ into counselling practice. By using the enhanced critical incident technique (Butterfield, Borgen, Maglio, & Amundson, 2009), this investigation sought to answer the following research question: How do counselling psychologists successfully integrate SJ into their practice? Six registered counsellors and two counselling psychologists from North America, who reported that that feel that they are doing well at integrating SJ into their practice were interviewed. Data analysis and interpretation identified contextual issues, common factors among positive and negative incidents of integrating SJ into counselling practice, as well as wish list items of resources that were not present at the time of integrating SJ, but that participants felt would have helped them to effectively integrate SJ into their counselling practice. To increase the trustworthiness of the research results, nine credibility checks were conducted throughout the study (Butterfield et al., 2009).

description: During the First World War soldiers from all combatant nations suffered from a wide range of debilitating nervous complaints as a result of the stresses and strains of modern warfare. War psychiatrists struggled to manage these complaints and shell-shocked men struggled to ensure that they had decent treatment and proper pensions. In each country the politics of shell shock differed but, regardless of context, men protested against unjust or inadequate treatment throughout Europe and the history of shell shock is part of a wider history of trauma and also a history of popular protest.

description: Wide, fragile binary stellar systems are found in the galactic field, and have recently been noted in the outskirts of expanding star clusters in numerical simulations. Energetically soft, with semi-major axes exceeding the initial size of their birth cluster, it is puzzling how these binaries are created and preserved. We provide an interpretation of the formation of these binaries that explains the total number formed and their distribution of energies. A population of weakly bound binaries can always be found in the cluster, in accordance with statistical detailed balance, limited at the soft end only by the current size of the cluster and whatever observational criteria are imposed. At any given time, the observed soft binary distribution is predominantly a snapshot of a transient population. However, there is a constantly growing population of long-lived soft binaries that are removed from the detailed balance cycle due to the changing density and velocity dispersion of an expanding cluster. The total number of wide binaries that form, and their energy distribution, are insensitive to the cluster population; the number is approximately one per cluster. This suggests that a population composed of many dissolved small-N clusters will more efficiently populate the field with wide binaries than that composed of dissolved large-N clusters. Locally such binaries are present at approximately the 2% level; thus the production rate is consistent with the field being populated by clusters with a median of a few hundred stars rather than a few thousand.

description: Let $\UT_n(q)$ denote the unitriangular group of unipotent $n\times n$ upper triangular matrices over a finite field with cardinality $q$ and prime characteristic $p$. It has been known for some time that when $p$ is fixed and $n$ is sufficiently large, $\UT_n(q)$ has ``exotic'' irreducible characters taking values outside the cyclotomic field $\QQ(ζ_p)$. However, all proofs of this fact to date have been both non-constructive and computer dependent. In a preliminary work, we defined a family of orthogonal characters decomposing the supercharacters of an arbitrary algebra group. By applying this construction to the unitriangular group, we are able to derive by hand an explicit description of a family of characters of $\UT_n(q)$ taking values in arbitrarily large cyclotomic fields. In particular, we prove that if $r$ is a positive integer power of $p$ and $n>6r$, then $\UT_n(q)$ has an irreducible character of degree $q^{5r^2-2r}$ which takes values outside $\QQ(ζ_{pr})$. By the same techniques, we are also able to construct explicit Kirillov functions which fail to be characters of $\UT_n(q)$ when $n>12$ and $q$ is arbitrary.

description: We demonstrate that dynamical noncommutative space-time will give rise to deformed oscillator algebras. In turn, starting from some q-deformations of these algebras in a two dimensional space for which the entire deformed Fock space can be constructed explicitly, we derive the commutation relations for the dynamical variables in noncommutative space-time. We compute minimal areas resulting from these relations, i.e. finitely extended regions for which it is impossible to resolve any substructure in form of measurable knowledge. The size of the regions we find is determined by the noncommutative constant and the deformation parameter q. Any object in this type of space-time structure has to be of membrane type or in certain limits of string type.
