Children as experimenters : elementary students' actions in an experimental context with magnets
Creators: name: Meyer, Karen
Publisher: name: University of British Columbia
Year: 2011

description: In science education the nature and value of science laboratory activities have become the subject of critical debate. Some science educators argue that a better understanding of what students do while purposefully engaged with materials would provide some answers. The intent of this study is to explore elementary students' actions and the knowledge they use while designing and conducting experiments. Four dyads each from grades 4 and 7 participated in three events. First, each pair was presented with a question (Which magnet is strongest?), two sets of magnets (one set at a time) and materials. The researcher observed and videotaped dyads' actions with materials until they made a conclusion for both magnet sets. Second, the researcher presented dyads with a selective set of materials to further explore their conceptions of magnetism. Finally, the pairs of students were interviewed while they watched the video of themselves experimenting during the first two events. The data were analyzed using an action theory perspective which emphasizes the cognitive nature of action. Students' models of magnetism were constructed from the data. Students used more than one model to explain different effects they observed. The designs of student experiments were grounded in their operational knowledge of the materials. Dyads generated data from a series of experiments whereby they manipulated different materials in a variety of ways. Dyads who obtained variable data did not repeat experiments to confirm or disconfirm results; rather they used specific strategies to make conclusions. The designs and procedures of experiments of students from both grades were similar, likely due to their common knowledge of the materials and their limited experience with open-ended tasks.

description: Light-matter strong coupling in the vacuum limit has been shown to enhance material properties over the past decade. Oxide nanoparticles are known to exhibit weak ferromagnetism due to vacancies in the lattice. Here we report the 700-fold enhancement of the ferromagnetism of YBa$_2$Cu$_3$O$_{7-x}$ nanoparticles under cooperative strong coupling at room temperature. The magnetic moment reaches 0.90 $μ_{\rm B}$/mol, and with such a high value, it competes with YBa$_2$Cu$_3$O$_{7-x}$ superconductivity at low temperature. This strong ferromagnetism at room temperature suggest that strong coupling is a new tool for the development of next generations of magnetic and spintronic nanodevices.

description: We study a sample of approximately 16,500 galaxies with I_AB <= 22.5 in the COSMOS field. Structural information on the galaxies is derived by fitting single Sersic models to their two-dimensional surface brightness distributions. We investigate the evolution of the number density of disk galaxies larger than 5 kpc between redshift z~1 and the present epoch. To this end, we use the measurements of the half-light radii to construct, as a function of redshift, the size function of both the total disk galaxy population and of disk galaxies split in four bins of bulge-to-disk ratio. Furthermore, we use a selected sample of roughly 1800 SDSS galaxies to calibrate our results with respect to the local universe. We find that: (i) The number density of disk galaxies with intermediate sizes (r_{1/2}~5-7 kpc) remains nearly constant from z~1 to today. (ii) The number density of the largest disks (r_{1/2}>7 kpc) decreases by a factor of about two out to z~1. (iii) There is a constancy in the number density of large bulgeless disks out to z~1; the deficit of large disks at early epochs seems to arise from a smaller number of bulged disks. Our results indicate that the bulk of the large disk galaxy population has completed its growth by z~1, and support the hypothesis that secular evolution processes produce - or at least add stellar mass to - the bulge components of disk galaxies.

description: We find that a $Z$-string is stable in a wide range of parameter space of the two Higgs doublet model due to a split into a pair of two topological $Z$-strings with fractional $Z$ fluxes. This configuration, a bound state of the two strings connected by a domain wall, is called a vortex molecule. Although the vortex molecule has no net topological charge, the locally induced topological charge density is polarized, namely distributed positively around one constituent string and negatively around the other constituent string, leading to the stability of the molecule. We numerically show that the vortex molecule is indeed a stable solution of the equation of motions in a much wider parameter space of the model than the usual axially symmetric $Z$-string in the Standard Model and the two Higgs doublet model, although it is not the case for experimental values of the parameters.

description: We report here discovery of Quasi Periodic Oscillations (QPOs) in the High Mass X-ray Binary (HMXB) Pulsar XTE J0111.20-7317 during a transient outburst in this source in December 1998. Using observations made with the proportional counter array of the Rossi X-ray Timing Explorer during the second peak and the declining phase of this outburst we have discovered a QPO feature at a frequency of 1.27 Hz. We have ruled out the possibility that the observed QPOs can instead be from the neighbouring bright X-ray pulsar SMC X-1. This is the highest frequency QPO feature ever detected in any HMXB pulsar. In the absence of a cyclotron absorption feature in the X-ray spectrum, the QPO feature, along with the pulse period and X-ray flux measurement measurement helps us to constrain the magnetic field strength of the neutron star.

description: Superconducting quantum computing technology has ushered in a new era of computational possibilities. While a considerable research effort has been geared toward improving the quantum technology and building the software stack to efficiently execute quantum algorithms with reduced error rate, effort toward optimizing how quantum output states are defined and classified for the purpose of reducing the error rate is still limited. To this end, this paper proposes DisQ, a quantum output state classification approach which reduces error rates of quantum programs on NISQ devices.

Conceptual change in a context of collegial consultation : a case of two secondary teachers
Creators: name: Hansby, Robin
Publisher: name: University of British Columbia
Year: 2011

description: This case study is based upon the experiences of Tim and Joe, two experienced, competent, reflective, secondary teachers who chose to engage, for the first time, in observing and discussing one another's lessons. The purpose of the study was to gain some insights into how teachers learn from each other and, more specifically, to describe the processes involved in teachers' conceptual change within a context of collegial consultation. It was hoped that framing collegial consultation in terms of teachers' conceptual change would demonstrate the value of such an activity, inform the collegial practice of teachers, and enable those who would facilitate this means of professional growth. Data consisted of field notes on observed lessons, transcripts of post-observation conferences, and transcripts of stimulated recall interviews conducted with each participant on each conference. These data were collected through four rounds of observation and were analysed for participants' conceptions and conceptual change, using the constant comparative method described by Glaser and Strauss (1967) and elaborated by Lincoln and Guba (1985). A constructivist perspective on learning (e.g. Von Glasersfeld, 1989) and a theory of conceptual change proposed by Posner, Strike, Hewson, and Gertzog (1982) informed the analysis. The results of this analysis were descriptions of some aspects of the participants' conceptions of teaching and collegial consultation, three examples of conceptual change, and a more detailed 'story' of conceptual change. Findings were constructed with respect to the nature of participants' conceptions, evidence of conceptual change, the process of conceptual change, events that contributed to conceptual change, and factors in the collegial relationship that seem to be associated with conceptual change. The findings of the study led to the general conclusions that (1) teachers will attempt to make sense of an anomalous situation by constructing an intelligible and initially plausible 'new' conception that resolves or explains the anomaly and (2) collegial consultation provides teachers with opportunities for experiences that initiate and enable such conceptual change. In addition to these two general conclusions, the findings of this study led to eight specific conclusions--four with respect to the process of conceptual change, and four 'parallel' conclusions with respect to collegial consultation.

description: We compare the non-linear matter power spectrum in real space calculated analytically from 3rd-order perturbation theory with N-body simulations at 11, the shape of oscillations is distorted from the linear theory prediction. Nevertheless, our results suggest that one can correct the distortion caused by non-linearity almost exactly. We also find that perturbation theory, which does not contain any free parameters, provides a significantly better fit to the simulations than the conventional approaches based on empirical fitting functions to simulations. The future work would include perturbation theory calculations of non-linearity in redshift space distortion and halo biasing in the weakly non-linear regime.

description: Consider a random walk $(S_n:n\geq0)$ with drift $-μ$ and $S_0=0$. Assuming that the increments have exponential moments, negative mean, and are strongly nonlattice, we provide a complete asymptotic expansion (in powers of $μ>0$) that corrects the diffusion approximation of the all time maximum $M=\max_{n\geq0}S_n$. Our results extend both the first-order correction of Siegmund [Adv. in Appl. Probab. 11 (1979) 701--719] and the full asymptotic expansion provided in the Gaussian case by Chang and Peres [Ann. Probab. 25 (1997) 787--802]. We also show that the Cramér--Lundberg constant (as a function of $μ$) admits an analytic extension throughout a neighborhood of the origin in the complex plane $\mathbb{C}$. Finally, when the increments of the random walk have nonnegative mean $μ$, we show that the Laplace transform, $E_μ\exp(-bR(\infty))$, of the limiting overshoot, $R(\infty)$, can be analytically extended throughout a disc centered at the origin in $\mathbb{C\times C}$ (jointly for both $b$ and $μ$). In addition, when the distribution of the increments is continuous and appropriately symmetric, we show that $E_μS_τ$ [where $τ$ is the first (strict) ascending ladder epoch] can be analytically extended to a disc centered at the origin in $\mathbb{C}$, generalizing the main result in [Ann. Probab. 25 (1997) 787--802] and extending a related result of Chang [Ann. Appl. Probab. 2 (1992) 714--738].

The resulting patent citation network provides a picture of the large-scale organization of innovations and its time evolution. Here we study the patterns of change of patents registered by the US Patent and Trademark Office (USPTO). We show that the scaling behavior exhibited by this network is consistent with a preferential attachment mechanism together with a Weibull-shaped aging term. Such attachment kernel is shared by scientific citation networks, thus indicating an universal type of mechanism linking ideas and designs and their evolution. The implications for evolutionary theory of innovation are discussed.

description: This work is on the effect of inflation on product financing of solar energy by delight limited, Lagos Nigeria. The objectives of the study were to determine the effect of cost-push inflation on debt financing and ascertain the effect of demand-pull inflation on equity financing of delight limited, Lagos Nigeria. A total population of one hundred (100) staff selected from the Lagos branches of delight Limited was used. Linear regression analysis was utilized to test the hypotheses of the study. The statistical tool used for the analysis is the statistical package for social sciences (SPSS) version 26. The findings of the study revealed that cost-push inflation does have significant effect on debt financing of delight limited, Lagos Nigeria and emand-pull inflation does have significant effect on equity financing of delight limited, Lagos Nigeria. The study concludes that that inflation, whether cost-push or demand-pull, plays a crucial role in shaping the financing options for solar energy companies such as delight Limited in Lagos, Nigeria. It was recommended among other things that the company adopts a proactive approach to managing its debt financing in the face of inflationary pressures

description: This research aims to investigate the morphological characteristics, chemical composition and possible sources of aerosol particles. Aerosol samples of the urban atmosphere were examined in the city of Vlora, located in the south of Albania. Scanning electron microscope JEOL JSM-563 equipped with an Oxford Link ISIS L300 for energy-dispersive X-ray [EDS] analysis was used to examine aerosol particles. In addition, images of aerosol particles were processed by ImageJ software for dimensional and morphological analyses. The primary data automatically generated by ImageJ were surface, perimeter, minimal and maximal size, circularity, and aspect ratio parameters. Then, the projected area diameter, volume equivalent diameter (dev), physical diameter, and aerodynamic diameter were calculated. Based on the results of particle morphology and chemical composition nine groups of aerosol particles were classified: aluminosilicates (fly ash and soil particles), Ca-rich particles, carbon particles (soot particles and biogenic particles), sea salt particles, Si-rich particles, Fe -rich particles, and mixed particles. The morphological analysis results indicated that aerosol particles were relatively distributed over a wide size range of 0.5 μm to 28 μm fitted to lognormal distributions. In the measured distributions a peak around 2 μm is dominant. By accounting for volume equivalent and diameter aerodynamic shape factor, this study develops the method of the aerodynamic diameter calculation.

description: The production of hydrogen fuels, via water splitting, is of practical relevance for meeting global energy needs and mitigating the environmental consequences of fossil-fuel-based transportation. Water photoelectrolysis has been proposed as a viable approach for generating hydrogen, provided that stable and inexpensive photocatalysts with conversion efficiencies over 10% can be discovered, synthesized at scale, and successfully deployed (Pinaud et al., Energy Environ. Sci., 2013, 6, 1983). While a number of first-principles studies have focused on the data-driven discovery of photocatalysts, in the absence of systematic experimental validation, the success rate of these predictions may be limited. We address this problem by developing a screening procedure with co-validation between experiment and theory to expedite the synthesis, characterization, and testing of the computationally predicted, most desirable materials. Starting with 70,150 compounds in the Materials Project database, the proposed protocol yielded 71 candidate photocatalysts, 11 of which were synthesized as single-phase materials. Experiments confirmed hydrogen generation and favorable band alignment for 6 of the 11 compounds, with the most promising ones belonging to the families of alkali and alkaline-earth indates and orthoplumbates. This study shows the accuracy of a nonempirical, Hubbard-corrected density-functional theory method to predict band gaps and band offsets at a fraction of the computational cost of hybrid functionals, and outlines an effective strategy to identify photocatalysts for solar hydrogen generation.

description: The non-linear dynamics of long-wavelength cosmological fluctuations may be phrased in terms of an effective classical, but stochastic evolution equation. The stochastic noise represents short-wavelength modes that continually redshift into the long-wavelength domain. The effective evolution may be derived from first principles quantum field theory in an expanding background, through a sequence of approximations calling for additional scrutiny. We perform such an analysis, putting particular emphasis on the amplitude of the stochastic noise, which ultimately determines the cosmological correlations and provides a non-perturbative IR regulator to the dynamics.

description: Solvent extraction (SX) is a common method used for nickel extraction, and conventional acidic extractants such as Cyanex 272, PC88A, and D2EHPA are typically employed. The extractant requires multi-step extraction and separating various metal impurities before the cobalt extraction stage. However, strict pH maintenance is needed during extraction, and strong acids must be used in stripping, which can negatively impact the environment and ecosystem. Treatments such as saponification are also required in conventional extractants to control the fall of pH and extraction value. The ionic liquid is a type of extract that is more environmentally friendly, harmless to the ecosystem and does not require further treatment such as saponification to get good results. One type that has been tried to separate cobalt from nickel is Phosphonium ionic liquids (PILs). The extraction value can exceed 95%, the use of acidic solutions is reduced, as well as proven to be more environmentally friendly. The advantages of ionic liquid are based on the lack of release of H+ ions in the by-product of the solvent extraction process and stripping agents can use deionized water very effectively. Further research on ionic liquid solvents such as PILs could bring us closer to the realization of an economically viable and environmentally friendly extraction process at an industrial scale.

description: New molecular line lists for calcium monohydride ($^{40}$Ca$^{1}$H) and magnesium monohydride ($^{24}$Mg$^{1}$H) and its minor isotopologues ($^{25}$Mg$^{1}$H and $^{26}$Mg$^{1}$H) are presented. The rotation-vibration-electronic (rovibronic) line lists, named \texttt{XAB}, consider transitions involving the \X, \A, and \BBp\ electronic states in the 0--30\,000~cm$^{-1}$ region (wavelengths $λ> 0.33$~$μ$m) and are suitable for temperatures up to 5000 K. A comprehensive analysis of the published spectroscopic literature on CaH and MgH is used to obtain new extensive datasets of accurate rovibronic energy levels with measurement uncertainties and consistent quantum number labelling. These datasets are used to produce new spectroscopic models for CaH and MgH, composed of newly empirically-refined potential energy curves and couplings in/between the different electronic states (e.g.\ spin-orbit, electronic angular momentum, Born-Oppenheimer breakdown, spin-rotation, $Λ$-doubling) and previously published \textit{ab initio} transition dipole moment curves. Along with Einstein $A$ coefficients, state lifetimes and Landé $g$-factors are provided, the latter being particularly useful as CaH and MgH can be used to probe stellar magnetic fields. Computed energy levels have been replaced with the more accurate empirical values (if available) when post-processing the line lists, thus tailoring the line lists to high resolution applications. The \texttt{XAB} line lists are available from the ExoMol database at http://www.exomol.com and the CDS astronomical database.

description: We calculate the ratios $R_{τ/ P}\equiv Γ\left( τ\to P ν_τ[γ] \right) / Γ\left(P\to μν_μ[γ]\right)$ ($P=π,K$) at one loop following a large-$N_C$ expansion where Chiral Perturbation Theory is enlarged by including the lightest resonances and respecting the short-distance behavior dictated by QCD.

We test the lepton universality, obtaining $\left|g_τ/g_μ\right|_π=0.9964\pm 0.0038$ and $\left|g_τ/g_μ\right|_K=0.9857\pm 0.0078$, and analyze the CKM unitarity, getting results at $2.1σ$ and $1.5σ$ from unitarity via $|V_{us}/V_{ud}|$ and $|V_{us}|$, respectively. We also update the search for non-standard interactions in $τ$ decays. As a by-product, we report the theoretical radiative corrections to the $τ\to P ν_τ[γ]$ decay rates: $δ_{τπ} = -(0.24 \pm 0.56) \%$ and $δ_{τK} = -(0.15 \pm 0.57) \%$.} \maketitle

description: While innovations in scientific instrumentation have pushed the boundaries of Mars rover mission capabilities, the increase in data complexity has pressured Mars Science Laboratory (MSL) and future Mars rover operations staff to quickly analyze complex data sets to meet progressively shorter tactical and strategic planning timelines. MSLWEB is an internal data tracking tool used by operations staff to perform first pass analysis on MSL image sequences, a series of products taken by the Mast camera, Mastcam. Mastcam's multiband multispectral image sequences require more complex analysis compared to standard 3-band RGB images. Typically, these are analyzed using traditional methods to identify unique features within the sequence. Given the short time frame of tactical planning in which downlinked images might need to be analyzed (within 5-10 hours before the next uplink), there exists a need to triage analysis time to focus on the most important sequences and parts of a sequence. We address this need by creating products for MSLWEB that use novelty detection to help operations staff identify unusual data that might be diagnostic of new or atypical compositions or mineralogies detected within an imaging scene. This was achieved in two ways: 1) by creating products for each sequence to identify novel regions in the image, and 2) by assigning multispectral sequences a sortable novelty score. These new products provide colorized heat maps of inferred novelty that operations staff can use to rapidly review downlinked data and focus their efforts on analyzing potentially new kinds of diagnostic multispectral signatures. This approach has the potential to guide scientists to new discoveries by quickly drawing their attention to often subtle variations not detectable with simple color composites.

description: R script for the analysis of the histopathological features of thoracic endometriosis (TE) using ggplot2, DT, pROC and vcd packages in R statistical software. The aim is to review the histopathological findings in TE, summarise the diagnostic features, identify any major histo-morphological indicator(s) hitherto unrecognised as such, suggest diagnostic algorithms; all with the aim of improving the diagnostic capacity and reducing observer error even where the clinical suspicion is low. Statistical methods applied include chi-squared test of independence, Cramér’s V test of strength of association and the area under the curve of the receiver operating characteristic (AUC-ROC) curve. The final conclusion is summarised with a Venn plot identifying endometrioid glands, ceroid macrophages, siderophages and lymphoid clusters as the major markers of TE.

description: It has long been suspected that powerful radio sources may lower the efficiency with which stars form from the molecular gas in their host galaxy, but so far, alternative mechanisms, in particular related to the stellar mass distribution in the massive bulges of their host galaxies, are not ruled out. We present new ALMA CO(1-0) interferometry of cold molecular gas in the nearby (z=0.0755), massive (M_stellar=4x10^11 M_sun), isolated, late-type spiral galaxy 2MASSX J23453269-044925, which is outstanding for having two pairs of powerful, giant radio jets, and a bright X-ray halo. The molecular gas is in a massive (M_gas=2x10^10 M_sun), 24 kpc wide, rapidly rotating ring, which is associated with the inner stellar disk. Broad (FWHM=70-180 km s^-1) lines with complex profiles associated with the radio source are seen over large regions in the ring, indicating gas velocities that are high enough to keep the otherwise marginally Toomre-stable gas from fragmenting into gravitationally bound, star-forming clouds. About 1-2% of the jet kinetic energy are required to power these motions. Resolved star-formation rate surface densities fall factors 50-75 short of expectations from the Kennicutt-Schmidt law of star-forming galaxies, and near gas-rich early-type galaxies with signatures of star formation lowered by jet feedback. We argue that radio AGN feedback is the only plausible mechanism to explain the low star-formation rates in this galaxy. Previous authors have already noted that the X-ray halo of J2345-0449 implies a baryon fraction near the cosmic average, which is very high for a galaxy. We contrast this finding with other, equally massive baryon-rich spiral galaxies without prominent radio sources. Most of the baryons in these galaxies are in stars, not in the halos. We also discuss the implications of our results for our general understanding of AGN feedback in massive galaxies.

Portrayal of world interdependence in social studies textbooks
Creators: name: Hannah, John Ogilvie Leo
Publisher: name: University of British Columbia
Year: 2011

description: This thesis focuses on how social studies textbooks, authorized for use in Canadian classrooms, portray our changing world. Preparing young people for citizenship in a world that is becoming increasingly interdependent requires presenting them with a way of thinking about the world that allows for consideration of alternative perspectives. The textbook, as a major vehicle for transmitting knowledge, can play an important role in that process. Although the volume of textual accounts of world interdependence is expanding, it is contended that the themes and images presented to students tend to reinforce unilateral rather than multilateral interpretations of reality. A framework of analysis is developed to determine if the textbooks employ either a multilateral thematic or unilateral thematic approach to the study of world interdependence. A multilateral approach encourages the exploration of different points of view on important world issues whereas a unilateral approach tends to focus on a particular interpretation of the same issues or events. This framework employs four rubrics suited to the analysis of the transmission of knowledge, description, explanation, prediction and prescription, to guide a series of analytical questions designed to determine if textbooks present unilateral or multilateral themes. Six significant world issue areas are evaluated in fourteen social studies textbooks. The issue areas profiled are: food supply issues, population issues, environmental issues, peace and security issues, human rights issues and economic Issues. The findings of this study indicate that the four dimensions of the framework are not adequately addressed in the selected textbooks. Twenty-two of the twenty-eight profiles studied tend to support a unilateral thematic rather than a multilateral thematic portrayal of how the world works. Preparing students for citizenship in a global age requires providing them with access to a body of knowledge that helps them to acquire a more integrated understanding of their world in order to make informed decisions and judgements about pressing global concerns. That goal is impeded when there is a propensity for textbooks to provide a particular viewpoint rather than a variety of viewpoints on important world Issues. Although this study is exploratory in nature, its findings present considerations for social studies educators when choosing to adopt particular textual materials for instructional purposes.

A Flexible Structured-based Representation for XML Document Mining

description: This paper reports on the INRIA group's approach to XML mining while participating in the INEX XML Mining track 2005. We use a flexible representation of XML documents that allows taking into account the structure only or both the structure and content. Our approach consists of representing XML documents by a set of their sub-paths, defined according to some criteria (length, root beginning, leaf ending). By considering those sub-paths as words, we can use standard methods for vocabulary reduction, and simple clustering methods such as K-means that scale well. We actually use an implementation of the clustering algorithm known as "dynamic clouds" that can work with distinct groups of independent variables put in separate variables. This is useful in our model since embedded sub-paths are not independent: we split potentially dependant paths into separate variables, resulting in each of them containing independant paths. Experiments with the INEX collections show good results for the structure-only collections, but our approach could not scale well for large structure-and-content collections.

description: Unsupervised health monitoring has gained much attention in the last decade as the most practical real-time structural health monitoring (SHM) approach. Among the proposed unsupervised techniques in the literature, there are still obstacles to robust and real-time health monitoring. These barriers include loss of information from dimensionality reduction in feature extraction steps, case-dependency of those steps, lack of a dynamic clustering, and detection results' sensitivity to user-defined parameters. This study introduces an unsupervised real-time SHM method with a mixture of low- and high-dimensional features without a case-dependent extraction scheme. Both features are used to train multi-ensembles of Generative Adversarial Networks (GAN) and one-class joint Gaussian distribution models (1-CG). A novelty detection system of limit-state functions based on GAN and 1-CG models' detection scores is constructed. The Resistance of those limit-state functions (detection thresholds) is tuned to user-defined parameters with the GAN-generated data objects by employing the Monte Carlo histogram sampling through a reliability-based analysis. The tuning makes the method robust to user-defined parameters, which is crucial as there is no rule for selecting those parameters in a real-time SHM. The proposed novelty detection framework is applied to two standard SHM datasets to illustrate its generalizability: Yellow Frame (twenty damage classes) and Z24 Bridge (fifteen damage classes). All different damage categories are identified with low sensitivity to the initial choice of user-defined parameters with both introduced dynamic and static baseline approaches with few or no false alarms.

description: We complete the computation of viscous transport coefficients in the near horizon geometries that arise from a stack of black Dp-branes for p=2,...,6 in the decoupling limit. The main new result is the obtention of the bulk viscosity which, for all p, is found to be related to the speed of sound by the simple relation ζ/η= -2(v_s^2-1/p). For completeness the shear viscosity is rederived from gravitational perturbations in the shear and scalar channels. We comment on technical issues like the counterterms needed, or the possible dependence on the conformal frame.
