description: The interaction between emerging magnetic flux and the pre-existing ambient field has become a "hot" topic for both numerical simulations and high-resolution observations of the solar atmosphere. The appearance of brightenings and surges during episodes of flux emergence is believed to be a signature of magnetic reconnection processes. We present an analysis of a small-scale flux emergence event in NOAA 10971, observed simultaneously with the Swedish 1-m Solar Telescope on La Palma and the \emph{Hinode} satellite during a joint campaign in September 2007. Extremely high-resolution G-band, H$α$, and \ion{Ca}{2} H filtergrams, \ion{Fe}{1} and \ion{Na}{1} magnetograms, EUV raster scans, and X-ray images show that the emerging region was associated with chromospheric, transition region and coronal brightenings, as well as with chromospheric surges. We suggest that these features were caused by magnetic reconnection at low altitude in the atmosphere. To support this idea, we perform potential and linear force-free field extrapolations using the FROMAGE service. The extrapolations show that the emergence site is cospatial with a 3D null point, from which a spine originates. This magnetic configuration and the overall orientation of the field lines above the emerging flux region are compatible with the structures observed in the different atmospheric layers, and remain stable against variations of the force-free field parameter. Our analysis supports the predictions of recent 3D numerical simulations that energetic phenomena may result from the interaction between emerging flux and the pre-existing chromospheric and coronal field.

Sexuality and disordered eating : a dimensional perspective
Creators: name: Dunkley, Cara Rae
Publisher: name: University of British Columbia

description: A growing body of research points to notable parallels between eating disorders and sexual dysfunctions. In addition to being highly comorbid, sexual dysfunctions and eating disorders have similarities in affective and cognitive characteristics, overlapping neurobiological features, and a shared treatment approach. These features provide theoretical evidence for an underlying, shared vulnerability which may serve as risk factors for the development and maintenance of both sexual concerns and disordered eating symptoms. Within the Hierarchical Taxonomy of Psychopathology (HiTOP) – an empirically derived dimensional system of nosology - sexual dysfunctions, eating disorders, and disorders of mood and anxiety are classified under an overarching spectrum of internalizing psychopathology. The current series of studies examines associations between eating disorder symptoms and sexual difficulties across multiple samples from an internalizing disorder perspective. Undergraduate women (n = 656) and clinical samples of women with an eating disorder (n = 120) and women with a chronic vulvar pain condition (n = 166) completed a series of online questionnaires assessing sexual function, sexual distress, sexual insecurities, eating disorder symptoms, body dissatisfaction, negative affect, and psychological features characteristic of eating disorders. In each sample, disordered eating symptoms, body dissatisfaction, and psychological features characteristic of eating disorders were associated with more sexual difficulties, and both psychological features characteristic of eating disorders and negative affect were found to mediate these associations. Women with an eating disorder also reported more sexual concerns than women in the undergraduate sample. These findings suggest that sexual difficulties are common among women with an eating disorder, and that the severity of eating disorder symptoms may be associated with the severity of sexual concerns. Examining sexuality in individuals with an eating disorder has the potential to inform prognosis, case conceptualization, and treatment planning. These findings lend support for the consideration of sexual concerns being included in the internalizing spectrum with specific reference to shared latent liability with eating disorders.

description: While the transport of matter by wheeled vehicles or legged robots can be guaranteed in engineered landscapes like roads or rails, locomotion prediction in complex environments like collapsed buildings or crop fields remains challenging. Inspired by principles of information transmission which allow signals to be reliably transmitted over noisy channels, we develop a ``matter transport" framework demonstrating that non-inertial locomotion can be provably generated over ``noisy" rugose landscapes (heterogeneities on the scale of locomotor dimensions). Experiments confirm that sufficient spatial redundancy in the form of serially-connected legged robots leads to reliable transport on such terrain without requiring sensing and control. Further analogies from communication theory coupled to advances in gaits (coding) and sensor-based feedback control (error detection/correction) can lead to agile locomotion in complex terradynamic regimes.

description: Attraverso la stesura di questo lavoro di diploma ho cercato di teorizzare e istituzionalizzare il CQT (acrostico di Controllo Qualità Testo), una metodologia che l’allievo impiega per arrivare a produrre un testo della massima efficacia in base alle proprie risorse e alla conoscenza di sé stesso. In primo luogo ci si prefigge di smontare la complessità della scrittura e di offrire gli strumenti necessari allo studente affinché egli riesca a produrre un testo leggero, logico nelle sue parti e lieve in superficie; secondariamente di rendere l’allievo consapevole del fatto che lo scrivere implica un dispendio di energie molto elevato. Non si poteva affrontare questa ricerca se non seguendo i principi metodologici della ricercaazione. L’obiettivo è stato quello di analizzare una pratica relativa a un campo di esperienza con lo scopo di introdurre, nella pratica stessa, dei cambiamenti migliorativi. Il lavoro è stato suddiviso in tre fasi principali: nella prima sono state definite le intenzioni educative del docente, fondamentali per avviare correttamente il lavoro con gli allievi; nella seconda è stato sottoposto agli allievi un questionario di valutazione intermedia che si prefiggeva di comprendere se la strada percorsa fino a quel punto fosse favorevole, o no, a perseguire nello sperimentalismo del CQT; nella terza sono state proposte alcune attività didattiche, suggerite dai risultati del questionario, al fine di pianificare e calibrare al meglio il prosieguo dell’anno scolastico.

description: We have investigated structural and magnetic phase transitions under high pressures in a quaternary rare earth transition metal arsenide oxide NdCoAsO compound that is isostructural to high temperature superconductor NdFeAsO. Four-probe electrical resistance measurements carried out in a designer diamond anvil cell show that the ferromagnetic Curie temperature and anti-ferromagnetic Neel temperature increase with an increase in pressure. High pressure x-ray diffraction studies using a synchrotron source show a structural phase transition from a tetragonal phase to a new crystallographic phase at a pressure of 23 GPa at 300 K. The NdCoAsO sample remained anti-ferromagnetic and non-superconducting to temperatures down to 10 K and to the highest pressure achieved in this experiment of 53 GPa. A P-T phase diagram for NdCoAsO is presented to a pressure of 53 GPa and low temperatures of 10 K.

description: The relationship of network structure and dynamics is one of the most extensively investigated problems in the theory of complex systems of the last years. Understanding this relationship is of relevance to a range of disciplines—from Neuroscience to Geomorphology. A major strategy of investigating this relationship is the quantitative comparison of a representation of network architecture (structural connectivity) with a (network) representation of the dynamics (functional connectivity). Here, we show that one can distinguish two classes of functional connectivity—one based on simultaneous activity (co-activity) of nodes, the other based on sequential activity of nodes. We delineate these two classes in different categories of dynamical processes—excitations, regular and chaotic oscillators—and provide examples for SC/FC correlations of both classes in each of these models. We expand the theoretical view of the SC/FC relationships, with conceptual instances of the SC and the two classes of FC for various application scenarios in Geomorphology, Ecology, Systems Biology, Neuroscience and Socio-Ecological Systems. Seeing the organisation of dynamical processes in a network either as governed by co-activity or by sequential activity allows us to bring some order in the myriad of observations relating structure and function of complex networks.

description: We present the results of simulations of forced turbulence in a slab where the mean kinetic helicity has a maximum near the mid-plane, generating gradients of magnetic helicity of both large and small-scale fields. We also study systems that have poorly conducting buffer zones away from the midplane in order to assess the effects of boundaries. The dynamical alpha quenching phenomenology requires that the magnetic helicity in the small-scale fields approaches a nearly static, gauge independent state. To stress-test this steady state condition we choose a system with a uniform sign of kinetic helicity, so that the total magnetic helicity can reach a steady state value only through fluxes through the boundary, which are themselves suppressed by the velocity boundary conditions. Even with such a set up, the small-scale magnetic helicity is found to reach a steady state. In agreement with earlier work, the magnetic helicity fluxes of small-scale fields are found to be turbulently diffusive. By comparing results with and without halos, we show that artificial constraints on magnetic helicity at the boundary do not have a significant impact on the evolution of the magnetic helicity, except that "softer" (halo) boundary conditions give a lower energy of the saturated mean magnetic field.

description: La presente ricerca si propone di indagare l’evoluzione della scuola dell’infanzia nella relazione con le famiglie, nell’evolversi della professione e nel mutato contesto in cui tutto questo avviene. A sostegno della ricerca storico-documentale, effettuata analizzando fonti primarie (in particolare leggi e regolamenti) e letteratura scientifica, ho cercato di approfondire quanto emerso con delle interviste semi-strutturate a 4 docenti di scuola dell’infanzia, con esperienza lavorativa di durata diversa, attualmente attive sul territorio ticinese. Dalla ricerca ho potuto individuare analogie e differenze, sia tra le testimonianze raccolte, sia nel confronto con le fonti storiche, che hanno permesso di indagare il vissuto professionale dei soggetti e stimolare la riflessione e il paragone tra passato e presente. Questi scambi comunicativi hanno inoltre accresciuto, in termini di apprendimento, il mio sapere - come pure spesso hanno incuriosito le mie interlocutrici -, permettendomi di stilare, sulla base di quanto poi emerso nelle interviste, un elenco di accorgimenti da tenere in considerazione nel delicato rapporto scuola-famiglie. Attraverso questo lavoro mi sono arricchita di un solido sapere professionale per cercare di diventare, sempre più, una professionista sicura e consapevole del proprio ruolo e dell’importanza che esso ricopre nella società.

description: In order to investigate the electronic state in the normal state of high-Tc cuprates in a wide range of temperature and hole-concentration, specific-heat, electrical-resistivity, magnetization and muon-spin-relaxation (muSR) measurements have been performed in non-superconducting Ni-substituted La2-xSrxCu1-yNiyO4 where the superconductivity is suppressed through the partial substitution of Ni for Cu without disturbing the Cu-spin correlation in the CuO2 plane so much. In the underdoped regime, it has been found that there exist both weakly localized holes around Ni and itinerant holes at high temperatures. With decreasing temperature, all holes tend to be localized, followed by the occurrence of variable-range hopping conduction at low temperatures. Finally, in the ground state, it has been found that each Ni2+ ion traps a hole strongly and that a magnetically ordered state appears. In the overdoped regime, on the other hand, it has been found that a Kondo-like state is formed around each Ni2+ spin at low temperatures. In conclusion, the ground state of non-superconducting La2-xSrxCu1-yNiyO4 changes upon hole doping from a magnetically ordered state with the strong hole-trapping by Ni2+ to a metallic state with Kondo-like behavior due to Ni2+ spins, and the quantum phase transition is crossover-like due to the phase separation into short-range magnetically ordered and metallic regions.

description: Land-use planning influences economic performance as it can intervene with location-specific and heterogeneous production externalities. This paper examines the impacts of heterogeneous externalities on local employment growth using a panel model framework with block-level land-use data inventory for Chicago. Cross-industry spillovers provide positive impacts on growth, but the mechanisms behind them differ across sectors and spatial scales. Improved understanding of heterogeneity in agglomeration economies can better support plan-making and urban economic performance. The results show significant and positive influence of cross-industry spillovers, a missing consideration in existing planning processes.

description: Conversational recommender systems (CRSs) aim to understand the information needs and preferences expressed in a dialogue to recommend suitable items to the user. Most of the existing conversational recommendation datasets are synthesized or simulated with crowdsourcing, which has a large gap with real-world scenarios. To bridge the gap, previous work contributes a dataset E-ConvRec, based on pre-sales dialogues between users and customer service staff in E-commerce scenarios. However, E-ConvRec only supplies coarse-grained annotations and general tasks for making recommendations in pre-sales dialogues. Different from that, we use real user needs as a clue to explore the E-commerce conversational recommendation in complex pre-sales dialogues, namely user needs-centric E-commerce conversational recommendation (UNECR). In this paper, we construct a user needs-centric E-commerce conversational recommendation dataset (U-NEED) from real-world E-commerce scenarios. U-NEED consists of 3 types of resources: (i) 7,698 fine-grained annotated pre-sales dialogues in 5 top categories (ii) 333,879 user behaviors and (iii) 332,148 product knowledge tuples. To facilitate the research of UNECR, we propose 5 critical tasks: (i) pre-sales dialogue understanding (ii) user needs elicitation (iii) user needs-based recommendation (iv) pre-sales dialogue generation and (v) pre-sales dialogue evaluation. We establish baseline methods and evaluation metrics for each task. We report experimental results of 5 tasks on U-NEED. We also report results in 3 typical categories. Experimental results indicate that the challenges of UNECR in various categories are different.

description: The Banach space $\ell_1(\Z)$ admits many non-isomorphic preduals, for example, $C(K)$ for any compact countable space $K$, along with many more exotic Banach spaces. In this paper, we impose an extra condition: the predual must make the bilateral shift on $\ell_1(\Z)$ weak$^*$-continuous. This is equivalent to making the natural convolution multiplication on $\ell_1(\Z)$ separately weak*-continuous and so turning $\ell_1(\Z)$ into a dual Banach algebra. We call such preduals \emph{shift-invariant}. It is known that the only shift-invariant predual arising from the standard duality between $C_0(K)$ (for countable locally compact $K$) and $\ell_1(\Z)$ is $c_0(\Z)$. We provide an explicit construction of an uncountable family of distinct preduals which do make the bilateral shift weak$^*$-continuous. Using Szlenk index arguments, we show that merely as Banach spaces, these are all isomorphic to $c_0$. We then build some theory to study such preduals, showing that they arise from certain semigroup compactifications of $\Z$. This allows us to produce a large number of other examples, including non-isometric preduals, and preduals which are not Banach space isomorphic to $c_0$.

The use of goal setting in improving first-year science and non-science major students' academic success and intrinsic motivation
Creators: name: Hay, Tristyn N.
Publisher: name: University of British Columbia
Year: 2021

description: The fundamental question this study aims to answer is one that many educational researchers are trying to understand: How can we best improve the academic success of our students? Students are most successful academically and otherwise when they are intrinsically motivated. Intrinsic motivation can be increased and maintained when student autonomy, competence and relatedness are nurtured (Deci & Ryan, 2000). As goal setting, particularly SMART goals, may help to embed these psychological requirements, this research sought to determine whether SMART goal setting will result in an increased level of intrinsic motivation and thus academic success. Levels of intrinsic motivation, metacognition and self-control along with grades were assessed in both science and non-science majors in first year post-secondary students utilizing pre- and post- self-reporting questionnaires and a single online goal setting intervention. When the intervention was received earlier in the term, science majors’ grades increased; however, no other responses were observed. In the non-majors there was an increase in self-control, control of learning beliefs, metacognition and intrinsic motivation three weeks following the intervention. Across both majors and non-majors, students’ self-control was also observed to be correlated with goal usage and goal completions. This study suggests that goal setting may be a worthwhile endeavor in the struggle to improve students’ academic success and persistence in first year post-secondary students.
A joint time-dependent density-functional theory for excited states of electronic systems in solution

description: We present a novel joint time-dependent density-functional theory for the description of solute-solvent systems in time-dependent external potentials. Starting with the exact quantum-mechanical action functional for both electrons and nuclei, we systematically eliminate solvent degrees of freedom and thus arrive at coarse-grained action functionals which retain the highly accurate \emph{ab initio} description for the solute and are, in principle, exact. This procedure allows us to examine approximations underlying popular embedding theories for excited states. Finally, we introduce a novel approximate action functional for the solute-water system and compute the solvato-chromic shift of the lowest singlet excited state of formaldehyde in aqueous solution, which is in good agreement with experimental findings.

During this unique solar minimum epoch, however, solar wind high - speed streams emanating from near-equatorial coronal holes occurred frequently and were the primary contributor to the recurrent geomagnetic activity at Earth. These conditions enabled the isolation of forcing by geomagnetic activity on the preconditioned solar minimum state of the upper atmosphere caused by Corotating Interaction Regions (CIRs). Thermosphere density observations around 400 km from the CHAMP satellite are used to study the thermosphere density response to solar wind high - speed streams/CIRs. Superposed epoch results show that thermosphere density responds to high - speed streams globally, and the density at 400 km changes by 75% on average. The relative changes of neutral density are comparable at different latitudes, although its variability is largest at high latitudes. In addition, the response of thermosphere density to high - speed streams is larger at night than in daytime, indicating the preconditioning effect of the thermosphere response to storms. Finally, the thermosphere density variations at the periods of 9 and 13.5 days associated with CIRs are linked to the spatial distribution of low - middle latitude coronal holes on the basis of the EUVI observations from the STEREO.

description: We report the discovery of KxFe2-yS2 single crystals, isostructural to KxFe2-ySe2 superconductors. The sulfide compound is a small gap semiconductor and shows spin-glass behavior below 32 K. Our results indicate that stoichiometry, defects, and the local environment of FeCh (Ch = S,Se) tetrahedra have important effects on the physical properties of isostructural and isoelectronic KxFe2-yCh2 compounds.

description: Young people, who are marginalised from conventional schooling, need equitable access to a full secondary school curriculum. In this study, Critical Discourse Theory identified power relations between such young people, youth workers, teachers, and administrators working with them in a flexible, community-based learning environment. A three-level discourse analysis uncovered the convivial and manipulative features of this environment and the impacts these features had on these young people’s future learning pathways. The research findings from this study have implications for the ways in which alternative learning environments engage young people and prepare them for their transition to life beyond senior secondary schooling.

description: Land-use planning influences economic performance as it can intervene with location-specific and heterogeneous production externalities. This paper examines the impacts of heterogeneous externalities on local employment growth using a panel model framework with block-level land-use data inventory for Chicago. Cross-industry spillovers provide positive impacts on growth, but the mechanisms behind them differ across sectors and spatial scales. Improved understanding of heterogeneity in agglomeration economies can better support plan-making and urban economic performance. The results show significant and positive influence of cross-industry spillovers, a missing consideration in existing planning processes.

description: Determination of design parameters based on electromagnetic simulations of microwave circuits is an iterative and often time-consuming procedure. Space mapping is a powerful technique to optimize such complex models by efficiently substituting accurate but expensive electromagnetic models, fine models, with fast and approximate models, coarse models. In this paper, we apply two space mapping, an explicit space mapping as well as an implicit and response residual space mapping, techniques to a case study application, a microstrip band-pass filter. First, we model the case study application and optimize its design parameters, using explicit space mapping modelling approach. Then, we use implicit and response residual space mapping approach to optimize the filter's design parameters. Finally, the performance of each design methods is evaluated. It is shown that the use of above-mentioned techniques leads to achieving satisfactory design solutions with a minimum number of computationally expensive fine model evaluations.

description: The structural properties of EuCo2As2 have been studied up to 35 GPa, through the use of x-ray diffraction in a diamond anvil cell at a synchrotron source. At ambient conditions, EuCo2As2 (I4/mmm) has a tetragonal lattice structure with a bulk modulus of 48 +/-4 GPa. With the application of pressure, the a-axis exhibits negative compressibility with a concurrent sharp decrease in c-axis length. The anomalous compressibility of the a-axis continues until 4.7 GPa, at which point the structure undergoes a second-order phase transition to a collapsed tetragonal (CT) state with a bulk modulus of 111 +/- 2 GPa. We found a strong correlation between the ambient pressure volume of 122 parents of superconductors and the corresponding tetragonal to collapsed tetragonal phase transition pressures

description: We revisit a classical continuum model for the diffusion of multiple species with size-exclusion constraint, which leads to a degenerate nonlinear cross-diffusion system. The purpose of this article is twofold: first, it aims at a systematic study of the question of existence of weak solutions and their long-time asymptotic behaviour. Second, it provides a weak-strong stability estimate for a wide range of coefficients, which had been missing so far. In order to achieve the results mentioned above, we exploit the formal gradient-flow structure of the model with respect to a logarithmic entropy, which leads to best estimates in the full-interaction case, where all cross-diffusion coefficients are non-zero. Those are crucial to obtain the minimal Sobolev regularity needed for a weak-strong stability result. For meaningful cases when some of the coefficients vanish, we provide a novel existence result based on approximation by the full-interaction case.

description: We consider the spin determination of new colored particles in the missing energy plus jets channel at the early stage of LHC. We use a three site moose model to describe the low energy Lagrangian of all same spin partner (LHT or UED like) models and check the gauge invariance of the amplitude. For the benchmark production and decay channel $pp \rightarrow U^{(R)} U^{(R)} \rightarrow u u B_H B_H$, in contrast to those in supersymmetric models, there are spin correlations which affect the polar and azimuthal angle distributions of the quarks from the heavy partner $U^{(R)}$ decay. We show such effects would be visible in the $E_{\rm T miss} / M_{\rm eff}$ distribution and the reconstructed azimuthal angle correlation using MAOS reconstruction.

description: Computer Mediated Courseware (CMC) has been developed so far for individual courses considering single or multiple text books. A group of courseware can be developed by using multiple text books and in this case, it is a requirement to cluster the contents of different books to form a generalized clustered content. No work has been found to develop courseware applying generalized clustered content. We have proposed a clustering of content supporting computer mediated courseware development based on data mining techniques to construct a hierarchical general structure of a group of courseware combining the individual structure of a set of books. The clustering will help the courseware developer to dynamically allocate contents to develop different courses using a group of books. The authors have applied this methodology for different level of courses on database. The methodology is generalized and can be applied to any other courses.
