description: An understanding of emotion regulation (ER) is important to children’s development, allowing for better navigation of the world. This learning happens in the company of caregivers, within the context of relationships inside and outside the home. Detrimental circumstances (e.g., poverty, lack of quality early childcare options, homelessness), however, exist for children in the United States. These factors have the potential to affect children’s academic readiness and success, resulting in them entering Kindergarten labeled at risk for school failure. To manage these factors and the at-risk characterization children receive, one solution has been to send children considered at risk to more school and school earlier (i.e., Universal Pre-Kindergarten, 3-K). Once in school, children spend more waking hours with teachers than with family. Given the importance of the dyadic relationship between teacher and child, much like the parent-child relationship, this researcher sought to understand if at-risk children are, in fact, favorably served by earlier school when teachers themselves operate under equal, but differing, types of stress. Using an explanatory sequential mixed-methods design, the researcher reanalyzed Chicago School Readiness Project (CSRP) data, looking for associations among teacher stress, teacher warmth, and children’s ability to regulate emotion; the researcher also qualitatively investigated Head Start (HS) teachers in the Chicago metropolitan area, asking (a) Do teachers exhibiting more warmth help children develop better emotion regulation (ER) skills? and (b) What are teachers’ lived experiences, histories, stories, and perspectives regarding child ER in relation to their own stress and warmth? Reanalysis of the CSRP data demonstrated teacher stress and teacher warmth were each associated with increased child externalizing and internalizing behaviors. Individual and focus group interview data of present-day HS teachers illuminated the problematic circles of influence in which HS teachers work, enriching the quantitative data. When children’s first years in school are considered a sensitive period, researchers, policymakers, and educators would do well to learn more about teachers who work around the realities and consequences of stress, as well as what their insights may offer to close the described achievement gap. Implications and recommendations are discussed.

description: This case study explores the relationship between teachers' language knowledge and their grammar teaching practices within the context of a bilingual school for the deaf in Sweden, a country that has demonstrated success in educating deaf children bilingually in written Swedish and Sweden's signed language. The study's participants were two Swedish language teachers and their 17 elementary school students; both participants were identified as high quality teachers and models of the school's approach to the bilingual education of deaf children. Teacher Language Awareness was selected as the theoretical construct through which to explore the relationship between teacher knowledge and practice because of its focus on knowledge-in-action, or the sites where knowledge intersects with practice. The study's main data sources were classroom observation and stimulated recall interviews. Data were analyzed sequentially using a start list of codes derived from a review of the relevant literature. Two portraits of the teachers' grammatical Teacher Language Awareness emerged from my analysis of the data. Suggested pedagogical applications for these portraits in teacher education programs are presented.

description: The present paper completes our earlier results on nonlinear stability of stationary solutions of the Vlasov-Poisson system in the stellar dynamics case. By minimizing the energy under a mass-Casimir constraint we construct a large class of isotropic, spherically symmetric steady states and prove their nonlinear stability against general, i. e., not necessarily symmetric perturbations. The class is optimal in a certain sense, in particular, it includes all polytropes of finite mass with decreasing dependence on the particle energy.

description: The Björkdal Mine is a gold mine situated 28 km northwest of Skellefteå in Northern Sweden and owned by Mandalay Resources since 2014. Mining operations started in 1988. In 2018 a new permit was granted to extend the life of the tailings management facility (TMF) for an additional 10 years, as well as increase the annual ore production by 30%, up to 1,7 million tonnes per annum. This extension of the TMF includes a 6.5 m raise of an existing dam, dam K1, and major extensions of both abutments. The raise results in approximately a three-fold increase of the total length of dam K1. Construction of the abutments brought specific challenges when it came to foundation works as the south extension involved foundation on saturated silt and the north on complicated bedrock. The silt foundation was required as the silt in this location, close to a waste rock dump, could not be excavated to the required depth. During construction, a control program with pore water pressure measurements was set up to maintain safe and stable conditions. The north extension included extensive excavation work in loose soils (peat and silt) to great depths, where bedrock was encountered. To conduct this excavation, the work had to take place during winter in frozen soils. The depth to bedrock was in line with previous investigations, but the complex surface and the quality of the bedrock became an unexpected challenge, with increased design work and extensive special measurements required. This paper will describe the foundation challenges of extending dam K1, as well as how these challenges affected the project.

description: The pion structure function is investigated in a simple model, where pion and constituent quark fields are coupled through the simplest pseudoscalar coupling. The imaginary part of the forward gamma* pi-> gamma* pi scattering amplitude is evaluated and related to the structure functions. It is shown that the introduction of non-perturbative effects, linked to the size of the pion and preserving gauge invariance, allows a connection with the quark distribution. It is predicted that higher-twist terms become negligible for Q2 larger than about 2 GeV2 and that quarks in the pion have a momentum fraction smaller than in the proton case.

description: Avoiding detection can provide significant survival advantages for prey, predators, or the military; conversely, maximizing visibility would be useful for signalling. One simple determinant of detectability is an animal's colour relative to its environment. But identifying the optimal colour to minimize (or maximize) detectability in a given natural environment is complex, partly because of the nature of the perceptual space. Here for the first time, using image processing techniques to embed targets into realistic environments together with psychophysics to estimate detectability and deep neural networks to interpolate between sampled colours, we propose a method to identify the optimal colour that either minimizes or maximizes visibility. We apply our approach in two natural environments (temperate forest and semi-arid desert) and show how a comparatively small number of samples can be used to predict robustly the most and least effective colours for camouflage. To illustrate how our approach can be generalized to other non-human visual systems, we also identify the optimum colours for concealment and visibility when viewed by simulated red-green colour-blind dichromats, typical for non-human mammals. Contrasting the results from these visual systems sheds light on why some predators seem, at least to humans, to have colouring that would appear detrimental to ambush hunting. We found that for simulated dichromatic observers, colour strongly affected detection time for both environments. In contrast, trichromatic observers were more effective at breaking camouflage.
Spinorial Structure of $O(3)$ and Application to Dark Matter

description: An $O(3)$ spinor, $Φ$, as a doublet denoted by ${\bf 2}_D$ consists of an $SO(3)$ spinor, $ϕ$, and its complex conjugate, $ϕ^\ast$, which form $Φ=\left(ϕ,ϕ^\ast\right)^T$ to be identified with a Majorana-type spinor of $O(4)$. The four gamma matrices $Γ_μ$ ($μ=1\sim 4$) are given by $Γ_i=\text{diag.}\left(τ_i,τ^\ast_i\right)$ ($i=1,2,3$) and $Γ_4=-τ_2\otimesτ_2$, where $τ_i$ denote the Pauli matrices. The rotations and axis-reflections of $O(3)$ are, respectively, generated by $Σ_{ij}$ and $Σ_{i4}$, where $Σ_{μν}=[Γ_μ,Γ_ν]/2i$. While $Φ$ is regarded as a scalar, a fermionic $O(3)$ spinor is constructed out of an $SO(3)$ doublet Dirac spinor and its charge conjugate. These $O(3)$ spinors are restricted to be neutral and cannot carry the standard model quantum numbers because they contain particles and antiparticles. Our $O(3)$ spinors serve as candidates of dark matter. The $O(3)$ symmetry in particle physics is visible when the invariance of interactions is considered by explicitly including their complex conjugates. It is possible to introduce a dark gauge symmetry based on $SO(3)\times\boldsymbol{Z}_2$ equivalent to $O(3)$, where the $\boldsymbol{Z}_2$ parity is described by a $U(1)$ charge giving 1 for a particle and $-1$ for an antiparticle. The $SO(3)$ and $U(1)$ gauge bosons turn out to transform as the axial vector of $O(3)$ and the pseudoscalar of $O(3)$, respectively. This property is related to the consistent definition of the nonabelian field strength tensor of $O(3)$ or of the U(1) charge of the O(3)-transformed spinor. To see the feasibility of our dark matter models, we discuss scalar dark matter phenomenology based on the dark $U(1)$ gauge model.

description: In inflationary cosmology, the particles constituting the Universe are created after inflation in the process of reheating due to their interaction with the oscillating inflaton field. In the bosonic sector, the leading channel of particle production is the non-perturbative regime of parametric resonance, preheating, during which bosons are created exponentially fast. Pauli blocking prohibits the unbounded creation of fermions. For this reason, it has been silently assumed that the creation of fermions can be treated with perturbation theory for the decay of individual inflatons. We consider the production of fermions interacting with the coherently oscillating inflatons. We find that the actual particle production occurs in a regime of the parametric excitation of fermions, leading to preheating of fermions. Fermion preheating differs significantly from the perturbative expectation. It turns out that the number density of fermions varies periodically with time. The total number of fermions quickly saturates to an average value within a broad range of momenta $\propto q^{1/4}$, where $q$ is the usual resonance parameter. The resonant excitation of fermions may affect the transfer inflaton energy, estimations of the reheating temperature, and the abundance of superheavy fermions and gravitinos. Back in the bosonic sector, outside of the parametric resonance bands there is an additional effect of parametric excitation of bosons with bounded occupation number in the momentum range $\propto q^{1/4}$.

description: Teachers represent a large portion of professional voice users in the United States and the development of poor vocal health has related to their work. Elementary music educators are expected to use their voices in both speech and song and are vocally active for much of their workday. This study investigates elementary music teachers’ conceptualization of their voices, what personal and professional value teachers place upon their voices, and how vocal health may affect, support, or detract from their careers. In this multiple case study conducted with three participants, a questionnaire addressed background demographics for the teacher and information regarding the music program. An interview collected more in depth data on thoughts and perceptions of voice use. Teachers completed the Voice Handicap Index and Singing Voice Handicap Index and each teacher was observed for one full workday. Vocal professionalism and caring for the voice’s professional use vary in definition and importance from teacher to teacher. Participants seem more conscious of their physical health than other aspects of professional vocal demand. Participants described themselves as vocal professionals while also engaging in behaviors which did not consistently support sustainable vocal health or hygiene. While each teacher viewed their voice as a professional tool, none had received training in the care of their voices, in what to do if their voice was injured, or in how to use their voices safely while teaching. Each teacher reported mild to no voice handicap on both the Voice Handicap Index and the Singing Voice Handicap Index. This may reflect some degree of label avoidance. Teachers at the elementary level of music come from diverse backgrounds and teach in widely varying circumstances. Teachers may hold some information on vocal health but may not have been trained in how to use the voice while teaching and may develop habitual practices which are not conducive to a career of healthy vocal production. Increased attention is indicated for the populations who professionally use their voices in both speech and song.

In the present paper, we define the Fock space representation $\mathcal{F}_{\mathbb{R}}$ of the quantum group $\mathbf{U}_\upsilon(\mathfrak{sl}(\mathbb{R}))$ as the vector space generated by real pyramids (a continuous generalization of the notion of partition). In addition, by using a variant of the "folding procedure" of Hayashi-Misra-Miwa, we define an action of $\mathbf{U}_\upsilon(\mathfrak{sl}(S^1))$ on $\mathcal{F}_{\mathbb{R}}$.

description: We present a class of static, spherically symmetric, non-singular solutions of the tree-level string effective action, truncated to first order in $α'$. In the string frame the solutions approach asymptotically (at $r\to 0$ and $r\to \infty$) two different anti-de Sitter configurations, thus interpolating between two maximally symmetric states of different constant curvature. The radial-dependent dilaton defines a string coupling which is everywhere finite, with a peak value that can be chosen arbitrarily small so as to neglect quantum-loop corrections. This example stresses the possible importance of finite-size $α'$ corrections, typical of string theory, in avoiding space-time singularities.

description: Der deutsche Leser – und nicht nur er – assoziiert beim Thema ‚Steuer – Italien‘ wohl in erster Linie Bestechung, Steuerflucht und brutale Razzien der Guardia di Finanza in den Urlaubsorten der Reichen und Schönen. Vielleicht weiß er auch, dass in Italien bis in die 1980er Jahre direkte Steuern vielfach von Steuerpächtern eingezogen wurden, und noch Ältere erinnern sich womöglich, dass nur wenig früher an den Ortseingängen noch Zollstellen waren, die dort von LKWs städtische Zuschlagsteuern kassierten. Und möglicherweise wurde ihm in den 1990er Jahren ja auch in Neapel oder anderswo im Süden nach dem Besuch eines Ladens oder Restaurants von „accompagnatori fiscali“ angeboten, sie die nächsten 500 Meter zu begleiten, um nötigenfalls den kontrollierenden ‚Finanzern‘ einen Kassenbon vorweisen zu können. Von allen diesen Dingen ist in Lars Döpkings Buch auch die Rede, aber es liefert keine Chronique scandaleuse, sondern seriöse Forschung.

description: A review of CP violation in the $B$ system and strategies to determine the unitarity triangle of the CKM matrix is given. We begin with an introduction to the description of CP violation in the Standard Model of electroweak interactions, and discuss the basic features of the theoretical framework to deal with non-leptonic B decays, which play the main role in this review. After a brief look at CP violation in the kaon system and a discussion of the rare decays $K^+\toπ^+ν\barν$ and $K_L\toπ^0ν\barν$, we turn to the formalism of $B^0_{d,s}$--$\bar{B^0_{d,s}}$ mixing, allowing us to explore important $B$-factory benchmark modes and the $B_s$-meson system. We then focus on charged B decays, $B\toπK$ modes and the phenomenology of $U$-spin related B decays, including the $B_d\toπ^+π^-$, $B_s\to K^+K^-$ system. Finally, we discuss a particularly simple -- but very predictive -- scenario for new physics, which is provided by models with ``minimal flavour violation''. In this framework, various bounds can be derived and interesting connections between the $B$ system and the rare kaon decays $K^+\toπ^+ν\barν$ and $K_L\toπ^0ν\barν$ arise.

description: A discrete random walk method on grids was proposed and used to solve the linearized Poisson-Boltzmann equation (LPBE) \cite{Rammile}. Here, we present a new and efficient grid-free random walk method. Based on a modified `` Walk On Spheres" (WOS) algorithm \cite{Elepov-Mihailov1973} for the LPBE, this Monte Carlo algorithm uses a survival probability distribution function for the random walker in a continuous and free diffusion region. The new simulation method is illustrated by computing four analytically solvable problems. In all cases, excellent agreement is observed.

description: Problem-solving skills, as a major component of mathematics curriculum, assist students to become equipped and competent individuals for the requirements of the century. The researcher used mixed method approaches to examine the relationship among in-service high school mathematics teachers’ backgrounds, beliefs, and skills about mathematical problem solving, and to analyze students’ approaches during problem-solving, and how they describe their problem-solving beliefs and their teachers’ mathematics instruction. Seven teachers and 91 students from one private and one public high school in the New York City area participated in the study. Both groups of participants completed belief questionnaires and mathematics activities which included problems with real-life contexts. Teachers also completed a background/opinion questionnaire. This study contributes deeper comprehension of the reasons behind developing problem-solving beliefs and skills. Statistical analysis did not reveal any significant correlation between teachers’ questionnaire responses and mathematics activity scores. However, working at these particular public and private school was an indicator of teachers’ belief scores, mathematics activity scores, and preferences of instructional methods. The qualitative analysis indicated that, for in-service teachers, taking problem solving courses in graduate school, participating in problem-solving related professional development activities, and enjoying freedom in the workplace to adopt more problem-solving centered instruction affected teachers’ problem solving skills and beliefs beneficially. The qualitative analysis of mathematics activities highlighted some common misunderstandings about certain mathematical contents and common approaches among students, such as performing random calculations with no apparent strategy, using wrong formulas, substituting erroneous numbers into equations. Also, most students experienced difficulties in understanding a problem and devising a plan to solve it. Although most students did not see themselves as strong problem solvers, they tended to stick with a problem until they solved it, tried new approaches, and were comfortable with making mistakes. Students generally showed agreement levels similar to those of their teachers for statements about looking back at answers, using different representatives, and encouraging different ways to solve the same problem. Students generally received lower scores on belief questionnaires and mathematics activities than did their teachers.

description: The damping of hot giant dipole resonances is investigated. The contribution of surface scattering is compared with the contribution from interparticle collisions. A unified response function is presented which includes surface damping as well as collisional damping. The surface damping enters the response via the Lyapunov exponent and the collisional damping via the relaxation time. The former is calculated for different shape deformations of quadrupole and octupole type. The surface as well as the collisional contribution each reproduce almost the experimental value, therefore we propose a proper weighting between both contributions related to their relative occurrence due to collision frequencies between particles and of particles with the surface. We find that for low and high temperatures the collisional contribution dominates whereas the surface damping is dominant around the temperatures $\sqrt{3}/2π$ of the centroid energy.

description: By work of Berglund and Madsen, the rings of rational characteristic classes of fibrations and smooth block bundles with fibre $D^{2n}\sharp(S^n\times S^n)^{\sharp g}$, relative to the boundary, are for $2n\ge 6$ independent of $g$ in degrees $*\le (g-6)/2$. In this note, we explain how this range can be improved to $*\le g-2$ using cohomological vanishing results due to Borel and classical invariant theory. This implies that the analogous ring for smooth bundles is independent of $g$ in the same range, provided the degree is small compared to the dimension.

description: Writing instruction has been neglected, both in teacher preparation courses and in professional development in literacy. Yet, the adoption of new standards and teacher evaluation systems by many states demands increased writing instruction and teacher “effectiveness” in providing it. Teachers, then, have faced higher expectations for writing instruction with little support for what those expectations mean or how to enact them in their own contexts. To meet these demands, it has been suggested that teachers must see themselves as writers in order to work most productively with children as writers. Therefore, if teachers must identify as writers to be “effective,” then teachers who do not identify as writers are also denied an identity as “good teachers.” These static, binary identity categories serve as “cover stories” to obscure a much more complicated reality.
      Informed by critical writing pedagogy and a literacy-and-identity studies framework, this study explored how teacher-writers in one school-based writing group perform, understand, and narrate their identities as writers and teachers of writing. Utilizing a narrative inquiry methodology for group meetings and interviews, I analyzed the complex, fluid, and sometimes contradictory identities of teacher-writers, and the construction, reconstruction, and mobilization of stories within and about the group. The static, binary identities group members claimed served as cover stories, the static categorical writer-selves that we construct in relation to our conceptions of an idealized writer. My study concluded that the relative autonomy of the writing group provided a shelter from the school culture of accountability where emotion and profanation were possible.
      This work proposed that, in acknowledging the complex nature of writing identities and the “unofficial” emotional lives of teachers, we can push beyond a static writer/non-writer binary and disrupt a hierarchical, outcome-based notion of staff development. As a result, space for staff development, in which a diverse school community joins together to engage in experiences, learning, and identity work that make space for emotion, may be created.
Testing causality violation on spacetimes with closed timelike curves

description: Generalized quantum mechanics is used to examine a simple two-particle scattering experiment in which there is a bounded region of closed timelike curves (CTCs) in the experiment's future. The transitional probability is shown to depend on the existence and distribution of the CTCs. The effect is therefore acausal, since the CTCs are in the experiment's causal future. The effect is due to the non-unitary evolution of the pre- and post-scattering particles as they pass through the region of CTCs. We use the time-machine spacetime developed by Politzer [1], in which CTCs are formed due to the identification of a single spatial region at one time with the same region at another time. For certain initial data, the total cross-section of a scattering experiment is shown to deviate from the standard value (the value predicted if no CTCs existed). It is shown that if the time machines are small, sparsely distributed, or far away, then the deviation in the total cross-section may be negligible as compared to the experimental error of even the most accurate measurements of cross-sections. For a spacetime with CTCs at all points, or one where microscopic time machines pervade the spacetime in the final moments before the big crunch, the total cross-section is shown to agree with the standard result (no CTCs) due to a cancellation effect.

description: Tailings Storage Facilities (TSFs) have the potential to impact Human Rights in several ways. The risks associated with TSFs include the potential for catastrophic failure, which can result in the loss of life, destruction of property, and irreversible harm to people, society, and the environment. In addition, the uncontrolled release of substances from TSFs can contaminate water sources, soils, and air, posing significant risks to human health and ecosystems. This can impact fundamental Human Rights such as the right to health, water, and a clean environment. In some cases, the rights of local communities to participate in decision-making processes, including the right to consultation and the right to free, prior, and informed consent (FPIC), are neglected in the TSF planning and design process. Furthermore, the construction and operation of TSFs can result in the displacement of communities and the loss of traditional lands and livelihoods, impacting the rights to property, culture, and an adequate standard of living. It is therefore essential to confirm that TSFs are planned, designed, constructed, operated, closed, and reclaimed in a manner that protects Human Rights, and also to conduct Human Rights impact assessments (HRIA) to identify and mitigate potential impacts. This paper aims to present the approach taken by Gold Fields to update the existing knowledge base and prepare a dedicated tailings HRIA, aligned to the GISTM, for the Tarkwa Gold Mine (TGM) in Ghana.

description: The in-class learning environments of a traditional and hybrid mathematics course were compared. The hybrid course had half the face-to-face meetings as the traditional course; outside of class, the students in the hybrid section completed asynchronous online assignments that involved watching content-delivery videos. Moving the content delivery outside of the classroom for the hybrid format had an impact on the interactions between the students and the professor inside the classroom. Quantitative and qualitative analysis of verbal discourse determined that the hybrid class format reduced the amount of in-class time devoted to direct instruction and increased the level of student discourse. Students assisted other students, had the freedom to make mistakes, and were able to receive personal guidance from the professor. The professor was able to address student misconceptions on formative assessments in class. Previous studies of the hybrid class model had focused on comparing differences in examination scores, GPAs, and pre- and post-test scores between the traditional and hybrid class model rather than comparing what is occurring inside the classroom. Quantifying what effect the shift from the traditional to the hybrid class model had on discourse inside the classroom is a first step towards confirming how the different methods of content delivery affects the in-class learning environment, and provides insight into certain pedagogic advantages the hybrid format may offer.

description: Source localization based on electroencephalography (EEG) has become a widely used neuroimagining technique. However its precision has been shown to be very dependent on how accurately the brain, head and scalp can be electrically modeled within the so-called forward problem. The construction of this model is traditionally performed by leveraging Finite Element or Boundary Element Methods (FEM or BEM). Even though the latter is more computationally efficient thanks to the smaller interaction matrices it yields and near-linear solvers, it has traditionally been used on simpler models than the former. Indeed, while FEM models taking into account the different media anisotropies are widely available, BEM models have been limited to isotropic, piecewise homogeneous models. In this work we introduce a new BEM scheme taking into account the anisotropies of the white matter. The boundary nature of the formulation allows for an efficient discretization and modelling of the fibrous nature of the white matter as one-dimensional basis functions, limiting the computational impact of their modelling. We compare our scheme against widely used formulations and establish its correctness in both canonical and realistic cases.
