description: The purpose of this study was to investigate the influence of a five-day summer residential mathematics and technology program on the mathematics motivation and self-efficacy of 210 middle-grades girls who participated in this female-only event. Entrance measures and gain scores were examined for the study sample as a whole and for demographic groups formed by race/ethnicity, family socioeconomic status, and grade level. The results show that this program favorably influenced participants’ short-term self-efficacy and motivation for learning mathematics. Overall, significant increases appeared in self-efficacy, intrinsic motivation, and extrinsic motivation from program beginning to end. Self-efficacy showed the strongest improvements, followed by intrinsic motivation, and finally extrinsic motivation. Some differences appeared among demographic subgroups.

description: This paper presents an approach to characterising the professional identity of technical vocational teachers based on psychosociological indicators. The indicators are based on the scientific literature and refer to the representation of colleagues and the profession to oneself and the representation of oneself as a person. A questionnaire survey was submitted to two groups of teachers with several years of service. The first group was made up of teachers with a professional degree. The second group consisted of contract teachers who teach without a professional diploma. This study shows the existence of several identity profiles of technical vocational training (TVET) teachers in Senegal.

description: We introduce positive cones on algebras with involution. These allow us to prove analogues of Artin's solution to Hilbert's 17th problem, the Artin-Schreier theorem characterizing formally real fields, and to define signatures with respect to positive cones. We consider the space of positive cones of an algebra with involution and investigate its topological properties, showing in particular that it is a spectral space. As an application we solve the problem of the existence of positive involutions.

description: Multivariate models for longitudinal data attempt to examine change in multiple variables as well as their interrelations over time. In this study, we present a Mixed-Effects Model with Crossed Random effects (MEM-CR) for individuals and variables, and compare it with two existing structural equation models for multivariate longitudinal data, namely the Curve-of-Factor-Scores (CUFFS) and the Factor-of-Curve-Scores (FOCUS). We compare these models in two types of longitudinal studies based on balanced and unbalanced data: panel studies and cohort-sequential designs, respectively. We illustrate the performance of these statistical techniques using empirical data from two studies (MHS, a panel study, and NLSY79, a cohort-sequential design) with discrete and continuous time metric modeling, respectively. We conclude that MEMs-CR provides relevant information about the developmental trajectories of individuals and variables in multivariate longitudinal data under either type of data condition. We discuss the theoretical and methodological implications of our findings.

description: Successful implementation of projects in NGOs within urban slums is a challenging endeavor to undertake due to government policy, scarcity of funding and stakeholders relationship on implementation of the project need utmost care. Hence, considering the stated difficulties the study is conducted using 28 respondents to analyze slum upgrading activity of Habitat for Humanity Ethiopia's in Addis Ababa through descriptive analysis. The study indicates positive effect of capacity building, stakeholder's relationships and implementation of project as well as timely implementation of project is the strength of the slum upgrading projects. Contrarily scarcity of finance and the government policy of 30/70 ratio of funding have adversely affected the projects. The study recommends the government need to revise it is policy on the financing of projects that has a direct influence on poverty reduction and welfare of the city's image.

description: Structural equation modeling (SEM) and path analysis using composite-scores are distinct classes of methods for modeling the relationship of theoretical constructs. The two classes of methods are integrated in the partial-least-squares approach to structural equation modeling (PLS-SEM), which systematically generates weighted composites and uses them to conduct path analysis of the structural model via the least-squares method. However, the goodness of PLS-SEM depends on the statistical properties of the composites, which are further determined by the formulations of the weights. This article studies how the formulations of PLS-SEM composites are affected by model specification, with focus on the sensitivity of the weights to common specification errors. Results indicate that the weights under PLS-SEM mode A are not affected by within-block error-covariances but those under mode B are. While between-block error-covariances and cross-loadings only affect the weights of the involved items under both PLS-SEM modes A and B, the weights under mode B are much more sensitive than those under mode A. In contrast, the weights under a recently proposed transformed mode (denoted as BA) are a compromise between those of modes A and B. The findings not only advance the understanding of the PLS-SEM methodology but also facilitate model diagnostics. Empirical applications of the results are illustrated via the analysis of a real dataset.
Microstructure-enabled control of wrinkling in nematic elastomer sheets

Year: 2016
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Nematic elastomers are rubbery solids which have liquid crystals incorporated into their polymer chains. These materials display many unusual mechanical properties, one such being the ability to form fine-scale microstructure. In this work, we explore the response of taut and appreciably stressed sheets made of nematic elastomer. Such sheets feature two potential instabilities -- the formation of fine-scale material microstructure and the formation of fine-scale wrinkles. We develop a theoretical framework to study these sheets that accounts for both instabilities, and we implement this framework numerically. Specifically, we show that these instabilities occur for distinct mesoscale stretches, and observe that microstructure is finer than wrinkles for physically relevant parameters. Therefore, we relax (i.e., implicitly but rigorously account for) the microstructure while we regularize (i.e., compute the details explicitly) the wrinkles. Using both analytical and numerical studies, we show that nematic elastomer sheets can suppress wrinkling by modifying the expected state of stress through the formation of microstructure.

description: We present an improved orderly algorithm for constructing all unlabelled lattices up to a given size, that is, an algorithm that constructs the minimal element of each isomorphism class relative to some total order. Our algorithm employs a stabiliser chain approach for cutting branches of the search space that cannot contain a minimal lattice; to make this work, we grow lattices by adding a new layer at a time, as opposed to adding one new element at a time, and we use a total order that is compatible with this modified strategy. The gain in speed is between one and two orders of magnitude. As an application, we compute the number of unlabelled lattices on 20 elements.

The possibility of gravitational self-interaction due to an attractive Bose-Einstein condensate is analyzed. The classical behavior of the scale factor of the universe is determined by a parameter associated with the Bose-Einstein fluid with bouncing or Big Crunch solutions. After we proceed to compute the finite-norm wave packet solutions to the Wheeler-DeWitt equation. The behavior of the scale factor is studied by applying the many-worlds interpretation of quantum mechanics. The quantum cosmological model is free from the singularities.

Hubbard-to-Heisenberg crossover (and efficient computation) of Drude weights at low temperatures
Creators: name: Karrasch, C.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We illustrate how finite-temperature charge and thermal Drude weights of one-dimensional systems can be obtained from the relaxation of initial states featuring global (left-right) gradients in the chemical potential or temperature. The approach is tested for spinless interacting fermions as well as for the Fermi-Hubbard model, and the behaviour in the vicinity of singular points (such as half filling or isotropic chains) is discussed. We present technical details on how to implement the calculation in practice using the density matrix renormalization group and show that the non-equilibrium dynamics is often less demanding to simulate numerically and features simpler finite-time transients than the corresponding linear response current correlators; thus, new parameter regimes can become accessible. As an application, we determine the thermal Drude weight of the Hubbard model for temperatures T which are an order of magnitude smaller than those reached in the equilibrium approach. This allows us to demonstrate that at low T and half filling, thermal transport is successively governed by spin excitations and described quantitatively by the Bethe ansatz Drude weight of the Heisenberg chain.

Numerische Auswertung von Funktionalintegralen über kohärente Zustände
Creators: name: Burghardt, Bernd
Publisher: name: Universität Dortmund
Year: 1999
Subjects: subject: 530

description: In der Arbeit wird ein neues numerisches Verfahren zur Lösung der Schrödinger - Gleichung vorgestellt. Für einen gegebenen Anfangszustand soll die zeitliche Entwicklung unter einem Hamilton - Operator mittels eines deterministischen Verfahrens berechnet werden. Hierfür wird eine Funktionalintegraldarstellung über kohärente Zustände benutzt. Die Funktionalintegralformulierung bedient sich einer verallgemeinerten Trotter - Formel und der Aufspaltung des Hamilton - Operators in einen harmonischen und einen anharmonischen Anteil. Die Umsetzung in ein numerisches Verfahren erfolgt über ein Vektor - Matrix - Multiplikations - Schema. Anhand von eindimensionalen Systemen (Morse - Potential, Doppelmuldenpotential) wird demonstriert, dass das Verfahren sowohl für zeitunabhängige als auch für zeitabhängige Hamilton - Operatoren in der Lage ist, über lange Zeiten stabile Ergebnisse zu liefern. Insbesondere konnte das von Großmann et al. (Phys. Rev. Lett., 67:516-519, 1991) an der periodisch getriebenen Doppelmulde entdeckte Phänomen des unterdrückten Tunnelns reproduziert werden. Dieses Problem beinhaltet drei verschiedene Zeitskalen, deren größte die kleinste um fünf Größenordnungen übertrifft.

description: We show that certain solutions to the linearized Einstein equation can---by the application of a particular type of linearized gauge transformation---be straightforwardly transformed into solutions of the exact Einstein equation. In cases with nontrivial matter content, the exact stress-energy tensor of the transformed metric has the same eigenvalues and eigenvectors as the linearized stress-energy tensor of the initial approximation. When our gauge exists, the tensorial structure of transformed metric perturbations identically eliminates all nonlinearities in Einstein's equation. As examples, we derive the exact Kerr and gravitational plane wave metrics from standard harmonic-gauge approximations.

description: We find a family of Kähler metrics invariantly defined on the radius $r_0>0$ tangent disk bundle ${{\cal T}_{M,r_0}}$ of any given real space-form $M$ or any of its quotients by discrete groups of isometries. Such metrics are complete in the non-negative curvature case and non-complete in the negative curvature case. If $\dim M=2$ and $M$ has constant sectional curvature $K\neq0$, then the Kähler manifolds ${{\cal T}_{M,r_0}}$ have holonomy $\mathrm{SU}(2)$; hence they are Ricci-flat. For $M=S^2$, just this dimension, the metric coincides with the Stenzel metric on the tangent manifold ${{\cal T}_{S^2}}$, giving us a new most natural description of this well-know metric.

description: Precisely modeling complex systems like cyber-physical systems is challenging, which often render model-based system verification techniques like model checking infeasible. To overcome this challenge, we propose a method called LAR to automatically `verify' such complex systems through a combination of learning, abstraction and refinement from a set of system log traces. We assume that log traces and sampling frequency are adequate to capture `enough' behaviour of the system. Given a safety property and the concrete system log traces as input, LAR automatically learns and refines system models, and produces two kinds of outputs. One is a counterexample with a bounded probability of being spurious. The other is a probabilistic model based on which the given property is `verified'. The model can be viewed as a proof obligation, i.e., the property is verified if the model is correct. It can also be used for subsequent system analysis activities like runtime monitoring or model-based testing. Our method has been implemented as a self-contained software toolkit. The evaluation on multiple benchmark systems as well as a real-world water treatment system shows promising results.

description: Metrics derived from Twitter and other social media---often referred to as altmetrics---are increasingly used to estimate the broader social impacts of scholarship. Such efforts, however, may produce highly misleading results, as the entities that participate in conversations about science on these platforms are largely unknown. For instance, if altmetric activities are generated mainly by scientists, does it really capture broader social impacts of science? Here we present a systematic approach to identifying and analyzing scientists on Twitter. Our method can identify scientists across many disciplines, without relying on external bibliographic data, and be easily adapted to identify other stakeholder groups in science. We investigate the demographics, sharing behaviors, and interconnectivity of the identified scientists. We find that Twitter has been employed by scholars across the disciplinary spectrum, with an over-representation of social and computer and information scientists; under-representation of mathematical, physical, and life scientists; and a better representation of women compared to scholarly publishing. Analysis of the sharing of URLs reveals a distinct imprint of scholarly sites, yet only a small fraction of shared URLs are science-related. We find an assortative mixing with respect to disciplines in the networks between scientists, suggesting the maintenance of disciplinary walls in social media. Our work contributes to the literature both methodologically and conceptually---we provide new methods for disambiguating and identifying particular actors on social media and describing the behaviors of scientists, thus providing foundational information for the construction and use of indicators on the basis of social media metrics.

We consider in particular a two-dimensional harmonic oscillator, which can serve as a model of a field mode on expanding space. We assume an initial wave function with small perturbations to the ground state. We present evidence that the trajectories are highly confined so as to preclude relaxation to equilibrium even over very long timescales. Cosmological implications are briefly discussed.

description: CMB and lensing reconstruction power spectra are powerful probes of cosmology. However they are correlated, since the CMB power spectra are lensed and the lensing reconstruction is constructed using CMB multipoles. We perform a full analysis of the auto- and cross-covariances, including polarization power spectra and minimum variance lensing estimators, and compare with simulations of idealized future CMB-S4 observations. Covariances sourced by fluctuations in the unlensed CMB and instrumental noise can largely be removed by using a realization-dependent subtraction of lensing reconstruction noise, leaving a relatively simple covariance model that is dominated by lensing-induced terms and well described by a small number of principal components. The correlations between the CMB and lensing power spectra will be detectable at the level of $\sim 5σ$ for a CMB-S4 mission, and neglecting those could underestimate some parameter error bars by several tens of percent. However we found that the inclusion of external priors or data sets to estimate parameter error bars can make the impact of the correlations almost negligible.

description: We compare two models for $\infty$-operads: the complete Segal operads of Barwick and the complete dendroidal Segal spaces of Cisinski and Moerdijk. Combining this with comparison results already in the literature, this implies that all known models for $\infty$-operads are equivalent - for instance, it follows that the homotopy theory of Lurie's $\infty$-operads is equivalent to that of dendroidal sets and that of simplicial operads.

description: Diese Arbeit vergleicht den Stand der Umwelterziehung in Griechenland mit dem in NRW. Umwelterziehung in NRW ist seit Jahren Bestandteil des Schulunterrichtes mit Einbeziehung von Dritten. In Griechenland ist die Umwelterziehung ein jüngerer Teilbereich des Erziehungswesens, das starre Strukturen unter straffer Führung durch das zentrale Erziehungsministerium ohne Einbeziehung von außerschulischen Organisationen aufweist. Umwelterziehung erfolgt auf freiwilliger Basis unter Kontrolle des Erziehungsministeriums. Der Vergleich der Lehrpläne und Richtlinien zeigt, daß der Lehrer in NRW Themen mit umwelterzieherischer Relevanz in jedem Fach und in jeder Jahrgangsstufe finden kann. Zudem ist fächerübergreifender Unterricht vorgesehen, der der Komplexität der Umwelterziehung Rechnung trägt. In Griechenland beziehen sich die Lehranweisungen auf das jeweilige Schulbuch und schreiben die Lehrinhalte vor. In den Schulbüchern werden Umweltthemen kaum behandelt. Auch lassen sich keine Hinweise auf Methoden finden, die sich speziell für die Umwelterziehung eignen. Effektive Umwelterziehung setzt voraus, daß der Unterricht auf Erleben, Erkennen, Begreifen und Schützen aufbaut. In NRW gibt es dazu ein breit gefächertes Angebot an außerschulischen Lernorten. Die Träger dieser Lernorte reichen vom Staat bis zu Privatpersonen mit nicht nur auf Schüler zugeschnittenen Programmen. Kinder können sich, auch in ihrer Freizeit, sinnvoll und intensiv mit der Natur beschäftigen. Griechenland bietet weder diese Vielfalt von Institutionen noch stehen die schulischen Umweltzentren anderen Interessierten außer Schulklassen offen. In Griechenland befähigt ein abgeschlossener Diplomstudiengang zum Beruf des Lehrers. In der Aus-und Fortbildung von Lehrern im Hinblick auf die Umwelterziehung fehlen didaktische und größtenteils auch pädagogische Lehrinhalte. Dieses Defizit führt allmählich dazu, daß Aus- und Fortbildungsveranstaltungen angeboten werden. Eine Untersuchung über den Stand der Umwelterziehung in Griechenland in Anlehnung an die Untersuchungen von Eulefeld 1988 und Hellberg-Rode 1992 belegt, daß die Hindernisse das Fehlen entsprechender Ausbildungsinhalte in den Studiengängen, der starre Unterrichtsablauf sowie die unzureichende Ausstattung der Schulen sind.

Anisotropic Boltzmann-Gibbs dynamics of strongly magnetized Vlasov-Fokker-Planck equations

description: We consider various sets of Vlasov-Fokker-Planck equations modeling the dynamics of charged particles in a plasma under the effect of a strong magnetic field. For each of them in a regime where the strength of the magnetic field is effectively stronger than that of collisions we first formally derive asymptotically reduced models. In this regime, strong anisotropic phenomena occur; while equilibrium along magnetic field lines is asymptotically reached our asymptotic models capture a non trivial dynamics in the perpendicular directions. We do check that in any case the obtained asymptotic model defines a well-posed dynamical system and when self consistent electric fields are neglected we provide a rigorous mathematical justification of the formally derived systems. In this last step we provide a complete control on solutions by developing anisotropic hypocoercive estimates.

description: Knowledge transfer has been a major concern in offshore outsourced telecom projects where new technologies and services are at stake. However the effect of knowledge transfer practices, challenges and influencing factors on the rate of organizational knowledge transfer has never caught the required attention. As a contribution to this gap, this paper aims to investigate the effect of current knowledge transfer practices (existence of strategies, processes and procedures, lessons learned, use of project knowledge repository, recognition scheme, training quality evaluation, IT and training opportunities), challenges (organizational readiness, organizational politics, organizational culture, national culture, and language barriers) and influencing factors (client- related, vendor-related, Knowledge complexity, transfer mechanism and relationships quality) on overall effectiveness of project knowledge transfer. The survey was conducted in ethio telecom and vendor organizations targeting project staffs that are familiar with the project environment. The study findings based on an overall sample response rate of 96.66% indicated that the current knowledge transfer practices are not mature in areas such as establishing processes and procedures, incentive schemes, and evaluation of training quality and content. There are also different challenges found to impact the effectiveness of knowledge transfer such as lack of organizational readiness, organizational politics, national culture, language barrier and informal relationships. Moreover, factors such as dissemination capability, willingness, trustworthiness, and knowledge complexity has been perceived as significant factors affecting knowledge transfer in outsourcing projects of the telecom sector.

description: We present in the first part cross sections for single pion production, quasi-elastic and deep inelastic scattering by muon and tau-neutrinos relevant for oscillation experiments, including nuclear effects. It will be useful for the study of neutrino oscillations in future oscillation experiments. In the second part we introduce a method to separate perturbative and non-perturbative parts in the dispersive sector of the Euler-Heisenberg Lagrangian density in strong (quasi-)Abelian fields. Further, using (modified) Borel-Pade approximation applied to the Euler-Heisenberg Lagrangian, we test numerically the approximate analytic continuation of the perturbative results into the nonperturbative sector.
Composites and Categories of Euclidean Jordan Algebras

description: We consider possible non-signaling composites of probabilistic models based on euclidean Jordan algebras (EJAs), satisfying some reasonable additional constraints motivated by the desire to construct dagger-compact categories of such models. We show that no such composite has the exceptional Jordan algebra as a direct summand, nor does any such composite exist if one factor has an exceptional summand, unless the other factor is a direct sum of one-dimensional Jordan algebras (representing essentially a classical system). Moreover, we show that any composite of simple, non-exceptional EJAs is a direct summand of their universal tensor product, sharply limiting the possibilities. These results warrant our focussing on concrete Jordan algebras of hermitian matrices, i.e., euclidean Jordan algebras with a preferred embedding in a complex matrix algebra}. We show that these can be organized in a natural way as a symmetric monoidal category, albeit one that is not compact closed. We then construct a related category InvQM of embedded euclidean Jordan algebras, having fewer objects but more morphisms, that is not only compact closed but dagger-compact. This category unifies finite-dimensional real, complex and quaternionic mixed-state quantum mechanics, except that the composite of two complex quantum systems comes with an extra classical bit. Our notion of composite requires neither tomographic locality, nor preservation of purity under tensor product. The categories we construct include examples in which both of these conditions fail. In such cases, the information capacity (the maximum number of mutually distinguishable states) of a composite is greater than the product of the capacities of its constituents.
