Cultural wealth for all : an analysis of the aesthetic values in the Getty's discipline-based art education program
Creators: name: Bergland, Donald Lowell
Publisher: name: University of British Columbia
Year: 2010

description: The Getty Center for Education in the Arts has issued a set of documents containing descriptions of its discipline-based art education program (DBAE). This program has been criticized as promoting a set of aesthetic values based solely in the Western fine art tradition, and hence may be insensitive to the educational needs of a modern democratic pluralistic society. Aesthetic value in this study refers to any criteria by which one visual experience is considered to be of greater import or value than another. Although the documents describing these values have been both attacked by critics and defended by the Getty, no sustained and in-depth analysis has been conducted to determine the nature and larger context of the aesthetic values they promote. This study analyzes the body of documents issued by the Getty in order to discover the nature of the aesthetic values and their larger context and purpose. Content analysis was performed on the publicly available Getty documents and all statements containing references to the nature, function, value, appreciation, criteria, standards, and judgment of art were extracted, analyzed and then classified and explicated insofar as they pertained to the criteria for determining superiority in a visual experience. Six criteria for aesthetic value were identified and characterized. These criteria defined the standard for superiority in terms of the art work, the fine art tradition, the visual code, literacy, and intellectual, cultural, and formal values. It was discovered that these criteria were part of a larger body of values which is based in the humanities tradition. After a discussion concerning the impact these values have in a modern democracy and the implications for Canadian art education, the study concludes that the kinds of aesthetic values promoted by the Getty's DBAE program are monocultural in that they exalt and promote only the values of the Western fine art tradition, and hence, may not be appropriate as the sole basis for art education in a pluralistic society. Curriculum frameworks for discipline-based art education which allow a more culturally democratic approach to the treatment of aesthetic values are available and these, rather than the Getty formulations should be utilized when designing discipline-based art education curricula.
Fast Collisionless Reconnection Condition and Self-Organization of Solar Coronal Heating

description: I propose that solar coronal heating is a self-regulating process that keeps the coronal plasma roughly marginally collisionless. The self-regulating mechanism is based on the interplay of two effects. First, plasma density controls coronal energy release via the transition between the slow collisional Sweet-Parker regime and the fast collisionless reconnection regime. This transition takes place when the Sweet--Parker layer becomes thinner than the characteristic collisionless reconnection scale. I present a simple criterion for this transition in terms of the upstream plasma density (n_e), the reconnecting (B_0) and guide (B_z) magnetic field components, and the global length (L) of the reconnection layer: L < 6.10^9 cm [n_e/(10^{10}/cm^3)]^(-3) (B_0/30G)^4 (B_0/B_z)^2. Next, coronal energy release by reconnection raises the ambient plasma density via chromospheric evaporation and this, in turn, temporarily inhibits subsequent reconnection involving the newly-reconnected loops. Over time, however, radiative cooling gradually lowers the density again below the critical value and fast reconnection again becomes possible. As a result, the density is highly inhomogeneous and intermittent but, statistically, does not deviate strongly from the critical value which is comparable with the observed coronal density. Thus, in the long run, the coronal heating process can be represented by repeating cycles that consist of fast reconnection events (i.e., nanoflares), followed by rapid evaporation episodes, followed by relatively long periods (1-hour) during which magnetic stresses build up and simultaneously the plasma cools down and precipitates.

description: We revisit a classic study [D. S. Hall {\it et al.}, Phys. Rev. Lett. {\bf 81}, 1539 (1998)] of interpenetrating Bose-Einstein condensates in the hyperfine states $\ket{F = 1, m_f = -1}\equiv\ket{1}$ and $\ket{F = 2, m_f = +1}\equiv\ket{2}$ of ${}^{87}$Rb and observe striking new non-equilibrium component separation dynamics in the form of oscillating ring-like structures. The process of component separation is not significantly damped, a finding that also contrasts sharply with earlier experimental work, allowing a clean first look at a collective excitation of a binary superfluid. We further demonstrate extraordinary quantitative agreement between theoretical and experimental results using a multi-component mean-field model with key additional features: the inclusion of atomic losses and the careful characterization of trap potentials (at the level of a fraction of a percent).

description: The paper deals with Herschel-Bulkley system describing a two-phase flow of blood trough vessels with rough walls. We analyze a stationary case with a variable viscosity depending on the boundary roughness. We derive the asymptotic formula for the blood velocity behavior in the limit when both vessel’s radius and the roughness period are small. Theoretical results are approved by numerical simulations. It turned out that the high boundary oscillations of vessel’s wall cause rapid oscillations of velocity.

description: This paper presents an efficient equivalent circuit approach (ECA), based on a Floquet modal expansion, for the study of the co- and cross-polarization in frequency selective surfaces (FSS) formed by periodic arrays of patches/apertures in either single or stacked configurations. The ECA makes it possible the derivation of analytical expressions for the generalized scattering parameters associated with the proposed circuit networks. Furthermore, the proposed circuit approach is an efficient surrogate model that can be combined with optimization techniques and artificial intelligence algorithms for the efficient design of FSS structures, saving efforts in the computation compared to time-consuming full-wave simulators and tedious synthesis (simulation-assisted) techniques. Due to the simplicity of the topology of the involved networks, the ECA can also be advantageously used to gain physical insight. The proposed approach is applied and validated in different FSS configurations where the cross-pol component plays a fundamental role in the design, as in circular polarizers, polarization rotators, and reflectarray cells.

description: We investigate the temporal dynamics of Doppler cooling of an initially hot single trapped atom in the weak binding regime using a semiclassical approach. We develop an analytical model for the simplest case of a single vibrational mode for a harmonic trap, and show how this model allows us to estimate the initial energy of the trapped particle by observing the fluorescence rate during the cooling process. The experimental implementation of this temperature measurement provides a way to measure atom heating rates by observing the temperature rise in the absence of cooling. This method is technically relatively simple compared to conventional sideband detection methods, and the two methods are in reasonable agreement. We also discuss the effects of RF micromotion, relevant for a trapped atomic ion, and the effect of coupling between the vibrational modes on the cooling dynamics.

description: The article considers issues related to increasing the competitiveness of domestic agricultural enterprises. Internal and external factors influencing the increase of competitiveness are determined. Research has shown that the assessment of the competitiveness of the enterprise is an important tool of strategic management, without proper attention to which it is almost impossible to optimize their activities and increase the degree of competitiveness for further promotion in other markets. Particular attention is paid to the factors that have the greatest impact on improving the competitiveness of the enterprise, taking into account the peculiarities of the modern agricultural market. Measures are proposed that have a direct impact on increasing the competitiveness of the organization.

description: The inclusive energy distributions of the complex fragments (3 $\leq$ Z $\leq$ 7) emitted from the bombardment of ^{12}C by ^{20}Ne beams with incident energies between 145 and 200 MeV have been measured in the angular range 10$^{o} \leq θ_{lab} \leq$ 50^{o}. Damped fragment yields in all the cases have been found to be the characteristic of emission from fully energy equilibrated composites. The binary fragment yields are compared with the standard statistical model predictions. Enhanced yields of entrance channel fragments (5 $\leq$ Z $\leq$ 7) indicate the survival of orbiting-like process in ^{20}Ne + ^{12}C system at these energies.

description: Cash payment is still king in several markets, accounting for more than 90\ of the payments in almost all the developing countries. The usage of mobile phones is pretty ordinary in this present era. Mobile phones have become an inseparable friend for many users, serving much more than just communication tools. Every subsequent person is heavily relying on them due to multifaceted usage and affordability. Every person wants to manage his/her daily transactions and related issues by using his/her mobile phone. With the rise and advancements of mobile-specific security, threats are evolving as well. In this paper, we provide a survey of various security models for mobile phones. We explore multiple proposed models of the mobile payment system (MPS), their technologies and comparisons, payment methods, different security mechanisms involved in MPS, and provide analysis of the encryption technologies, authentication methods, and firewall in MPS. We also present current challenges and future directions of mobile phone security.

An approach to teaching metaphoric understanding and metaphoric expression in the visual arts
Creators: name: Ehlers, Wendy Joan
Publisher: name: University of British Columbia
Year: 2010

description: This thesis advances the proposition that a program of study designed to improve recognition and understanding of metaphor in the art and literature of others, will assist post-secondary Fine Arts students with expressing metaphoric thought in their own imagery. Twenty-two first year college students responded to a ten week investigation of metaphor, with a variety of visual and written assignments, demonstrating how their ability to recognize, understand and use metaphor was affected over the period of the study. Several approaches to the problem of expressing metaphor with visual language are identified and described, and the results are compared. Many of the products motivated by a preconceived, deliberate approach to visual metaphor relied upon visual and written information gathered from vicarious sources. These images lacked a sense of personal involvement between the student and his subject. Those images that relied upon direct, personal involvement with a particular set of qualities possessed by the subject, initiated more spontaneous expressions. The conclusions drawn from the study suggest that, while a theoretical knowledge of metaphor provides students with a necessary conceptual foundation to recognize and understand the meaning of metaphor, authentic expressions of metaphoric thought are more likely to occur when a less deliberate approach to visual metaphor is taken. Theoretical knowledge of metaphor can be applied more effectively to the process of critical analysis and interpretation of visual imagery; while the making of visual imagery may be more appropriately served by intuitive use of metaphor.

description: Estimating an optimal individualized treatment rule (ITR) based on patients’ information is an important problem in precision medicine. An optimal ITR is a decision function that optimizes patients’ expected clinical outcomes. Many existing methods in the literature are designed for binary treatment settings with the interest of a continuous outcome. Much less work has been done on estimating optimal ITRs in multiple treatment settings with good interpretations. In this article, we propose angle-based direct learning (AD-learning) to efficiently estimate optimal ITRs with multiple treatments. Our proposed method can be applied to various types of outcomes, such as continuous, survival, or binary outcomes. Moreover, it has an interesting geometric interpretation on the effect of different treatments for each individual patient, which can help doctors and patients make better decisions. Finite sample error bounds have been established to provide a theoretical guarantee for AD-learning. Finally, we demonstrate the superior performance of our method via an extensive simulation study and real data applications. Supplementary materials for this article are available online.

description: We use the VESPA algorithm and spectra from the Sloan Digital Sky Survey to investigate the star formation history of the host galaxies of 257 Type Ia supernovae. We find 5$σ$ evidence for a short-lived population of progenitors with lifetimes of less than 180 Myr, indicating a Type Ia supernova channel arising from stars in the mass range $\sim$3.5-8 $M_\odot$. As standardizeable candles, Type Ia supernovae play an important role in determining the expansion history of the Universe, but to be useful for future cosmological surveys, the peak luminosity needs to be free of uncorrected systematic effects at the level of 1-2%. If the different progenitor routes lead to supernovae with even moderately small differences in properties, then these need to be corrected for separately, or they could lead to a systematic bias in future supernovae surveys, as the prompt route is likely to increase in importance at high redshift. VESPA analysis of hosts could be a valuable tool in this, by identifying which progenitor route is most likely.

description: This study looked at four types of learning environments for developmentally delayed 3-5 year old preschool children, namely segregated programs, reversed mainstreamed programs, day care centres, and nursery schools in order to describe and analyze the experiences children have in these settings. Twenty preschool classroom environments were analyzed, forty children were observed to obtain child-child interaction data, twenty teachers were observed and interviewed in order to gather information on teacher-child interaction and type and amount of support services available to the programs and sixty parents of special needs children were interviewed to obtain information on parental involvement. The analysis of the environment indicated that statistically significant differences existed in the data between the scores obtained by the different types of centres. Higher scores were obtained by segregated and reversed mainstreamed programs than day care centres. No significant statistical differences were found between types of settings for child-child interaction and teacher-child interaction, although there were large differences among centres within a type. Special needs children across settings were observed mostly in parallel, solitary, and associative play. Little cooperative and dramatic play was observed across types of settings. Teachers in all types of settings spent a high portion of their time talking to children on a one-to-one basis. Teachers in day care centres spent significantly more time talking to children about matters related to misbehavior rather than academics. Little use of praise and corrective feedback was observed by teachers of special needs preschool children. Greater availability and higher expectations for parental involvement existed both in segregated and reversed mainstreamed programs than in day care centres for parents of special needs children. Support services for preschool programs were very low in the community the research sampled.

description: L’attention des élèves en classe est un sujet qui questionne depuis de nombreuses années. Notre réflexion sur ce questionnement nous a poussé à conduire une étude basée sur l’introduction du mouvement durant des périodes définies de la journée et d’en observer l’effet sur les élèves. Cette pratique devait nous permettre de voir si cela augmentait l’attention des élèves durant l’enseignement. Lors de cette recherche, nous avons utilisé le système d’observation des incidents disciplinaires (SOID) (Brunelle et al., 1993) pour observer les comportements perturbateurs. L’expérience s’est déroulée de la manière suivante : pendant quatre jours dans deux classes de degrés différents, nous avons alterné des périodes d’enseignement en intégrant parfois du mouvement. Nous avons observé et filmé six élèves que nous avions préalablement sélectionnés dans chaque classe, dans le but de relever l’ensemble de leurs comportements perturbateurs. Nous avons identifié trois catégories : les élèves atteints de TDAH, les élèves avec des facilités scolaires et les élèves avec difficultés scolaires. Nos observations nous ont permis d’analyser les effets de notre pratique sur les élèves. À la fin de notre étude, nous avons constaté que la mise en place du mouvement dans notre pratique a été bénéfique pour la majorité des élèves mais surtout pour les élèves atteints de TDAH. Cependant, elle a eu des répercussions négatives sur un élève présentant des comportements déviants.
VP12-23: Research on Electromagnetic Transformation and Raising Knee Frequency of Hybrid Medium High Frequency Transformer
Creators: Chang-Hung Hsu

Sensors, High Frequency Devices, and Power Devices (Virtual)
Transformer core material determines its operating frequency and magnetic flux saturation density due to its natural characteristics. This research proposes a design, simulation and experimental discussion of a composite miniature high-frequency transformer (HFT). In this paper, the artificial intelligence-like neural network algorithm is used to model the HFT transformer, and the calculation and evaluation are carried out from the aspects of core mathematical modeling, low core loss, high load power and operating efficiency, as shown in Figure 1. A medium-frequency high-power (MFHP) transformer is one of the most important components of a dc/dc converter, as shown in Figure 2. In the design application, consider the circulating current it has in the parallel secondary winding of the thin winding, and the primary series secondary parallel structure. Based on the asymmetrical mutual inductance phenomenon i.e. asymmetrical coupling between primary and secondary windings (primary-series secondary-parallel, PSSP) situation, this will not achieve an absolutely symmetrical result. There is an inflection point frequency for medium and high frequency operation of the transformer, and setting the operating frequency of the transformer at the inflection point frequency will result in an increase in the AC resistance. Therefore, this study uses the artificial intelligence algorithm to predict the position of the inflection point frequency caused by the asymmetric coupling of the winding. The neural network model analyzes the asymmetric coupling coefficient of the transformer, and compares the prediction with the calculation of the actual scaled transformer's corner frequency. Finally, based on the consideration of the inflection point frequency optimized by the experiment, it is used to construct the development and research of the miniature medium and high frequency transformer with PSSP structure.References: [1] M.

description: We propose a new form of the colour-kinematics/double-copy duality for heavy-mass effective field theories, which we apply to construct compact expressions for tree amplitudes with heavy matter particles in Yang-Mills and in gravity to leading order in the mass. In this set-up, the new BCJ numerators are fixed uniquely and directly written in terms of field strengths, making gauge invariance manifest. Furthermore, they are local and automatically satisfy the Jacobi relations and crossing symmetry. We construct these BCJ numerators explicitly up to six particles. We also discuss relations of the BCJ numerators in the heavy-mass effective theory with those in pure Yang-Mills amplitudes.

description: SoulCollage® in the experience of a group of autobiographical writing in artistic mediation. 
SoulCollage® is a method of collage that is rooted in Jungian theories and humanistic psychology. Developed in the ‘80s, in America, by Seena Frost, Jungian psychoanalyst, it invites and guides – according to a specific methodo- logy – to the construction a “deck” of cards which, taken all together, represent the uniqueness and multiplicity of the person. Based on the principle of freedom of asso- ciation (in the choice of the images) and what Jung, in his Red Book , called “active imagination”, is easy, fun and affordable for all, lends itself to sharing in groups and can be used in different contexts, from the family, the school and group meetings, up to counseling and various forms of psychotherapy and even psychiatric rehabilitation. SoulCollage® gives participants the opportunity to be together, in a creative way, ba- sed on mutual acceptance, and reflect on themselves. The cards that are built form the collage, in permanent evolution, of each person, in particular of his or her elements of personality, of the component relating to the community of personal affects, of the physical energies, and of the most important archetypes in personal life. The rappor- teur has made experience of SoulCollage® (along with other methods of artistic media- tion) in the groups of autobiographical writing she leads and will explain how to use this method in such a context.

description: From sensation to expression: metaphors, synaesthesia and oxymora in the “now moments” of poetry and clinical sessions.
 “Now moments” according to Daniel Stern are special and critical moments that happen within a psychotherapy session or, more in general, within a significant relationship: empathy and strong bonds are part of those moments as well as unpredictable and unavoidable outcomes. Interpersonal love relationships are made of such contrasting elements that imply surprise effects but also the growing of mutual and reassuring links. The aim of this paper is to show how also in the poetry structures “now moments” play an important role. Rhetorical figures such metaphors, synesthesia and oxymora go beyond the words in search of a significant interpersonal or intrapersonal contact that is a process con- cerning somehow expression and regulation of emotions. In so far as most of the rhe- torical figures come from pre-linguistic realms (such as sensation and perception) some forms of those figures may be present in nonverbal languages as music and may be successfully used in many art therapy models and methods.

description: Equilibration of observables in closed quantum systems that are described by a unitary time evolution is a meanwhile well-established phenomenon apart from a few equally well-established exceptions. Here we report the surprising theoretical observation that integrable as well as non-integrable spin rings with nearest-neighbor or long-range isotropic Heisenberg interaction not only equilibrate but moreover also synchronize the directions of the expectation values of the individual spins. We highlight that this differs from spontaneous synchronization in quantum dissipative systems. Here, we observe mutual synchronization of local spin directions in closed systems under unitary time evolution. Contrary to dissipative systems, this synchronization is independent of whether the interaction is ferro- or antiferromagnetic. In our numerical simulations, we investigate the free induction decay (FID) of an ensemble of up to $N = 25$ quantum spins with $s = 1/2$ each by solving the time-dependent Schrödinger equation numerically exactly. Our findings are related to, but not fully explained by conservation laws of the system. The synchronization is very robust against for instance random fluctuations of the Heisenberg couplings and inhomogeneous magnetic fields. Synchronization is not observed with strong enough symmetry-breaking interactions such as the dipolar interaction. We also compare our results to closed-system classical spin dynamics which does not exhibit phase synchronization due to the lack of entanglement. For classical spin systems the fixed magnitude of individual spins effectively acts like additional $N$ conservation laws.

School improvement and the culture of the school
Creators: name: Riecken, Theodore John
Publisher: name: University of British Columbia
Year: 2010

description: This study was an investigation of one elementary school staffs experience with a school-based school improvement program. Using the conception of school "culture" as an analytic construct, the investigator examined the interaction of the culture of the school with a locally developed school improvement program. For the purposes of this investigation, culture was defined as a commonly held set of values and beliefs. Using interviews and participant-observation, the researcher collected data from the school setting over an eight month period. Observational and interview data along with data in the form of program documents and minutes of staff meetings were analyzed to obtain a) an understanding of the shared values and beliefs that constitute the culture of the school and, b) a picture of the developing relationship between the culture of the school and the school improvement program. Data pertaining to the culture of the school was analyzed and categorized into seven broad themes that appeared to characterize the school's culture. As a further refinement of the construct of theme, five "key suppositions" were identified. These key suppositions consisted of shared values and beliefs about a particular topic, and were seen as the cultural nexus of the school. They included a set of commonly held values and beliefs about the importance of 1) active involvement of students in learning, 2) ongoing professional development, 3) a cooperative ethos among staff, 4) active administrative leadership, and 5) time as a valuable commodity in the school environment. Using these key suppositions as a framework for analysis, the researcher examined the interaction of the school improvement program with the culture of the school. Analysis of the program's implementation in the school indicated that there was a reciprocal interaction between the program and the school's culture. There was evidence to indicate that three of the key suppositions had an influence on the way the program was implemented in the school. The key suppositions that had an influence on the program's implementation were 1) active involvement of students in learning, 2) active administrative leadership, and 3) time as a valuable commodity in the school environment. There was also evidence to indicate that the school improvement program acted to strengthen two of the key suppositions of the school's culture. The key suppositions that were strengthened were 1) a cooperative ethos, and 2) ongoing professional development. An examination of teachers' perceptions of the school Improvement process indicated that, on occasion, the improvement process held the potential for conflict when staff engaged in debate about multiple interpretations of some of the program materials. The researcher has hypothesized that in such situations of potential conflict, the culture of the school acted as a stabilizing mechanism in that it provided staff with a common set of assumptions on which to focus their school improvement efforts.

description: Data collected in various scientific fields are count data. One way to analyze such data is to compare the individual levels of the factor treatment using multiple comparisons. However, the measured individuals are often clustered–e.g. according to litter or rearing. This must be considered when estimating the parameters by a repeated measurement model. In addition, ignoring the overdispersion to which count data is prone leads to an increase of the type one error rate. We carry out simulation studies using several different data settings and compare different multiple contrast tests with parameter estimates from generalized estimation equations and generalized linear mixed models in order to observe coverage and rejection probabilities. We generate overdispersed, clustered count data in small samples as can be observed in many biological settings. We have found that the generalized estimation equations outperform generalized linear mixed models if the variance-sandwich estimator is correctly specified. Furthermore, generalized linear mixed models show problems with the convergence rate under certain data settings, but there are model implementations with lower implications exists. Finally, we use an example of genetic data to demonstrate the application of the multiple contrast test and the problems of ignoring strong overdispersion.
$B_c$ meson exclusive decays to a $P$-wave charmonium and a pion at NLO accuracy

description: In this paper, we calculate the next-to-leading order (NLO) quantum chromodynamics (QCD) corrections to the exclusive processes $B_c^+\to χ_{cJ}(h_c)π^+$ in the framework of the nonrelativistic QCD (NRQCD) factorization formalism. The results show that NLO QCD corrections markedly enhance the branching ratios with $K$ factors of about 2.5. In combination with the study of $B_c^+\to J/ψπ^+$, we find that the NLO NRQCD prediction for the ratio of branching fractions $\frac{\mathcal{B}(B_c^+\to χ_{c0}π^+)}{\mathcal{B}(B_c^+\to J/ψπ^+)}$ is then compatible with the experimental measurement.

description: We study the ground state one-body correlation function in the Lieb-Liniger model. In the spectral representation, correlations are built from contributions stemming from different excited states of the model. We aim to understand which excited states carry significant contributions, specifically focusing on the small energy-momentum part of the dynamic one-body function. We conjecture that relevant excitations take form similar to two-spinon states known from XXZ spin chain. We validate this hypothesis by numerical evaluation of the correlator with ABACUS algorithm and by analytical computations in the strongly interacting regime.
