description: In this article, we construct a supersymmetric real mass deformation for the adjoint chiral multiplets in the gauge theory describing the dynamics of a stack of D2-branes in type II string theory. We do so by placing the D2-branes into the T-dual of a supersymmetric NS fluxbrane background. We furthermore note that this background is the string theoretic realization of an Omega-deformation of flat space in the directions transverse to the branes where the deformation parameters satisfy ε_1 = - ε_2. This Ω-deformation therefore serves to give supersymmetric real masses to the chiral multiplets of the 3D gauge theory. To illustrate the physical effect of the real mass term, we derive BPS-saturated classical solutions for the branes rotating in this background. Finally, we reproduce all the same structure in the presence of NS fivebranes and comment on the relationship to the gauge theory/spin-chain correspondence of Nekrasov and Shatashvili.

description: Young children in families experiencing deep poverty – those with incomes below 50 percent of the federal poverty line -- are likely to experience severe early adversities that contribute to poor health and education outcomes. This brief offers information about young children, age birth to nine, living in deep poverty in New York State, and about policies that could support their healthy development and success. It includes information about the state and county-level prevalence and characteristics of these children and recommendations for strengthening family and work support policies and developing new two-generation policies that could promote better outcomes for young children and families in deep poverty.

description: We derive the primordial power spectrum of density fluctuations in the framework of quantum cosmology. For this purpose we perform a Born-Oppenheimer approximation to the Wheeler-DeWitt equation for an inflationary universe with a scalar field. In this way we first recover the scale-invariant power spectrum that is found as an approximation in the simplest inflationary models. We then obtain quantum gravitational corrections to this spectrum and discuss whether they lead to measurable signatures in the CMB anisotropy spectrum. The non-observation so far of such corrections translates into an upper bound on the energy scale of inflation.

The best interests of the child and the potential of collaborative family law : a critical analysis of collaborative lawyers' perspectives on important issues in collaborative practice
Creators: name: Ledger, Matthew
Publisher: name: University of British Columbia
Year: 2017

description: Children are very important to the future of Canadian society. In addition to being one of the most cherished aspects of parents’ lives, they represent Canada’s future politically, economically and socially. Family conflict, and resulting events such as divorce or separation, can represent a significant challenge to healthy child development. The manner in which family disputes are resolved between parents therefore has an important role to play in ensuring the healthy development of children. To that end, it is incumbent upon those engaged with the topic of family dispute resolution, to further explore family dispute resolution methods that have potential to help achieve these goals. Collaborative family law, with its emphasis on a more holistic approach to resolving family disputes, appears to be one promising method. The literature review contained herein reveals the potential of collaborative law to help children and families. It also identifies several key issues with the collaborative process that collaborative lawyers should think about when trying to achieve this goal. The interview study that forms a key part of this thesis is focused on the collaborative family law model practiced in the Vancouver area. The study involved semi-structured interviews of ten collaborative lawyers. A set of standard questions, and flexible follow ups as necessary, were asked of each lawyer, concerning difficult issues with collaborative family law as identified in the literature. The goal of these interviews was to obtain lawyers’ perspectives on important issues facing their practice. Few such studies have been done in Canada. The result was an in depth exploration and critical analysis of major issues facing those practicing collaborative family law, and how collaborative lawyers in the Vancouver area address these issues. The success of collaborative family law at maximizing its benefit to families is arguably contingent upon suitable families choosing the collaborative process, as well as the proper execution of the process to suit the individual needs of each family. Hopefully, the discussion herein will further the pursuit of these objectives.

description: When President Obama took office in 2009, he faced the worst recession since the Great Depression. As a direct response to the economic crisis, the American Recovery and Reinvestment Act (ARRA) introduced a series of coordinated investments in the economy with the goals of spurring job creation, increasing economic spending, and creating a new foundation for long-term prosperity for all working families. The Recovery Act increased funding for health care, education and entitlement programs by $224 billion. Specifically, states received $1.2 billion through the Workforce Investment Act (WIA) youth funds to provide employment and training services targeted to disadvantaged youth. At a recent White House Briefing organized by the Office of Public Engagement, the administration announced a number of ARRA-funded job creation initiatives. Officials identified two promising priorities for future job-related investments: The TANF Emergency Contingency Fund; The Summer Youth Employment Initiative. The TANF Emergency Contingency Fund, created through ARRA with $5 billion to cover FY2009 and FY2010, helps states serve more families that seek employment opportunities and assistance during the economic downturn. The TANF Emergency Fund served as a resource for job creation by subsidizing state employment programs and initiatives (such as paid work, work-study, etc). According to recent estimates, more than 100,000 jobs will be created by the time authorization expires. The Summer Youth Employment Initiative (SYEI), implemented last summer, has enrolled 355,000 youth in summer jobs nationwide. This is a critical program not only for stimulating the local economy in depressed communities but offering income support to families through youth employment. Through SYEI, public and private employers worked with states and counties to create summer youth internships and programs that provided financial support through the summer and linked them to year-round career readiness programs and skills training for the future. The administration is currently evaluating ARRA-funding programs with an eye towards investments that have far-reaching impacts across communities and on the economy. Moving forward, the administration will focus on youth employment as a critical workforce and economic development strategy.

This removes the "ordinary" hypothesis required in previous work of the author.

description: Technical grade vitreous silica was dissolved hydrothermally in NaOH lyes. Liquid sodium water glasses with silica concentrations of up to 26.4 wt % and molar SiO2:Na2O ratios of up to 3.5 were obtained. The dissolution behavior showed two temperature regimes: up to 130 °C the SiO2 content approached a final solubility limit controlled by cristobalite crystallization. Above 130 °C, crystallization of low quartz restricted solubility. The dissolution kinetics were governed by surface area reduction and saturation control according to the Noyce-Whitney law.
Random maximal isotropic subspaces and Selmer groups

description: Under suitable hypotheses, we construct a probability measure on the set of closed maximal isotropic subspaces of a locally compact quadratic space over F_p. A random subspace chosen with respect to this measure is discrete with probability 1, and the dimension of its intersection with a fixed compact open maximal isotropic subspace is a certain nonnegative-integer-valued random variable. We then prove that the p-Selmer group of an elliptic curve is naturally the intersection of a discrete maximal isotropic subspace with a compact open maximal isotropic subspace in a locally compact quadratic space over F_p. By modeling the first subspace as being random, we can explain the known phenomena regarding distribution of Selmer ranks, such as the theorems of Heath-Brown, Swinnerton-Dyer, and Kane for 2-Selmer groups in certain families of quadratic twists, and the average size of 2- and 3-Selmer groups as computed by Bhargava and Shankar. Our model is compatible with Delaunay's heuristics for p-torsion in Shafarevich-Tate groups, and predicts that the average rank of elliptic curves over a fixed number field is at most 1/2. Many of our results generalize to abelian varieties over global fields.

description: We study dynamical surface gravity in a general spherically symmetric setting using Painlevé-Gullstrand (PG) coordinates. Our analysis includes several definitions that have been proposed in the past as well as two new definitions adapted to PG coordinates. Various properties are considered, including general covariance, value at extremality, locality and static limit. We illustrate with specific examples of "dirty" black holes that even for spacetimes possessing a global timelike Killing vector, local definitions of surface gravity can differ substantially from "non-local" ones that require an asymptotic normalization condition. Finally, we present numerical calculations of dynamical surface gravity for black hole formation via spherically symmetric scalar field collapse. Our results highlight the differences between the various definitions in a dynamical setting and provide further insight into the distinction between local and non-local definitions of surface gravity.

description: The critical rheology of sheared frictional granular materials near jamming transition is numer- ically investigated. It is confirmed that there exist a true critical density which characterizes the onset of the yield stress, and two fictitious critical densities which characterize the scaling laws of rheological properties. We find the existence of a hysteresis loop between two of the critical densities for each friction coefficient. It is noteworthy that the critical scaling law for frictionless jamming transition seems to be still valid even for frictional jamming despite using fictitious critical density values.

description: Within the academic debate about good citizenship, several authors have emphasized different possible notions – such as adhesion to more traditional-elitist, solidarity-based or participative norms (Denters, Gabriel, & Torcal, 2007). Recently, scholars have proposed the use of person- centred approaches to analyze typologies of good citizenship conceptions (Hooghe, Oser & Marien, 2016; Reichert, 2016). The existing studies have not addressed until now the European political context or investigated ideas of good citizenship related to a supranational level. The present study examines by means of latent profile analysis young people’s patterns of adhesion to different notions about what is a good European citizen and investigates how the different groups are characterized by socio-demographic characteristics, levels of participation and perceptions of belonging or political alienation related to the European context. The study is part of the Catch-EyoU project and uses the pilot questionnaire data with a sample of 994 respondents from two age groups –adolescents (16-19 years old, 52.7%) and young adults (20-26 years old, 47.3%)– collected in eight European countries. The results identified five different profiles that distinguished between youth who held a mixed conception of the good European citizen (where different normative ideas coexist), groups that emphasized a particular view and a pattern of low adhesion to all theorized conceptions. While most respondents give high importance on both traditional and more participative norms, the findings confirm the existence of comparatively more passive views and of a critically oriented group differentiated by more negative perception of the European context.

description: These are challenging economic times for American families, especially those headed by lowwage workers. But state policy can play an important role in helping those who work hard achieve economic security for their families. This document outlines why state policymakers need to pay more attention to low-wage work, its effects on families and children, and what it takes for low-wage workers to make their families economically secure. It also describes a set of State Family Economic Security Profiles that the National Center for Children in Poverty (NCCP) designed to highlight policy options available to state policymakers, the choices each state has made, and how families are doing economically in all 50 states and the District of Columbia.

description: While analyzing decades of very long baseline interferometry (VLBI) data, we detected the secular aberration drift of the extragalatic radio source proper motions caused by the rotation of the Solar System barycenter around the Galactic center. Our results agree with the predicted estimate to be 4-6 micro arcseconds per year (μas/yr) towards α = 266\circ and δ = -29\circ. In addition, we tried to detect the quadrupole systematics of the velocity field. The analysis method consisted of three steps. First, we analyzed geodetic and astrometric VLBI data to produce radio source coordinate time series. Second, we fitted proper motions of 555 sources with long observational histories over the period 1990-2010 to their respective coordinate time series. Finally, we fitted vector spherical harmonic components of degrees 1 and 2 to the proper motion field. Within the error bars, the magnitude and the direction of the dipole component agree with predictions. The dipole vector has an amplitude of 6.4 \pm 1.5 μas/yr and is directed towards equatorial coordinates α = 263\circ and δ = -20\circ. The quadrupole component has not been detected. The primordial gravitational wave density, integrated over a range of frequencies less than 10-9 Hz, has a limit of 0.0042 h-2 where h is the normalized Hubble constant is H0/(100 km s-1).
Revisiting global trends in freshwater insect biodiversity: a reply

description: Jähnig et al. make some useful points regarding the conclusions that can be drawn from our meta-analysis; however, some issues require clarification. First, we never suggested that there was a globally increasing trend of freshwater insect abundances, but only spoke of an average increasing trend in the available data. We also did not suggest that freshwater quality has improved globally, but rather that documented improvements in water quality can explain at least some of the trends we observed. Second, as we acknowledged, our data are not a representative set of freshwater ecosystems around the world, but they are what is currently accessible. Third, there is indeed no doubt that changes in abundance or biomass need not correlate with changes in other aspects of biodiversity, such as species richness or functional composition. Our analysis was specifically focused on trends in community abundance/biomass because it has been the subject of recent study and speculation, and is a widely available metric in long-term studies. To better understand the recent changes in freshwater insect assemblages, we encourage freshwater ecologists to further open their troves of data from countless long-term monitoring schemes so that larger and more comprehensive syntheses can be undertaken.

description: Quantum walk represents one of the most promising resources for the simulation of physical quantum systems, and has also emerged as an alternative to the standard circuit model for quantum computing. Up to now the experimental implementations have been restricted to single particle quantum walk, while very recently the quantum walks of two identical photons have been reported. Here, for the first time, we investigate how the particle statistics, either bosonic or fermionic, influences a two-particle discrete quantum walk. Such experiment has been realized by adopting two-photon entangled states and integrated photonic circuits. The polarization entanglement was exploited to simulate the bunching-antibunching feature of non interacting bosons and fermions. To this scope a novel three-dimensional geometry for the waveguide circuit is introduced, which allows accurate polarization independent behaviour, maintaining a remarkable control on both phase and balancement.

description: We probe in some depth into the structure of eleven-dimensional, osp(32|1)-based Chern-Simons supergravity, as put forward by Troncoso and Zanelli (TZ) in 1997. We find that the TZ Lagrangian may be cast as a polynomial in 1/l, where l is a length, and compute explicitly the first three dominant terms. The term proportional to 1/l^9 turns out to be essentially the Lagrangian of the standard 1978 supergravity theory of Cremmer, Julia and Scherk, thus establishing a previously unknown relation between the two theories. The computation is nontrivial because, when written in a sufficiently explicit way, the TZ Lagrangian has roughly one thousand non-explicitly Lorentz-covariant terms. Specially designed algebraic techniques are used to accomplish the results.

On the Meaning of the Principle of General Covariance
Creators: name: Chamorro, Alberto
Publisher: name: arXiv
Year: 2011
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We present a definite formulation of the Principle of General Covariance (GCP) as a Principle of General Relativity with physical content and thus susceptible of verification or contradiction. To that end it is useful to introduce a kind of coordinates, that we call quasi-Minkowskian coordinates (QMC), as an empirical extension of the Minkowskian coordinates employed by the inertial observers in flat space-time to general observers in the curved situations in presence of gravitation. The QMC are operationally defined by some of the operational protocols through which the inertial observers determine their Minkowskian coordinates and may be mathematically characterized in a neighbourhood of the world-line of the corresponding observer. It is taken care of the fact that the set of all the operational protocols which are equivalent to measure a quantity in flat space-time split into inequivalent subsets of operational prescriptions under the presence of a gravitational field or when the observer is not inertial. We deal with the Hole Argument by resorting to de idea of the QMC and show how it is the metric field that supplies the physical meaning of coordinates and individuates point-events in regions of space-time where no other fields exist. Because of that the GCP has also value as a guiding principle supporting Einstein's appreciation of its heuristic worth in his reply to Kretschmann in 1918.

description: Recent experiments revealed the importance of higher-band effects for the Mott insulator (MI) -- superfluid transition (SF) of ultracold bosonic atoms or mixtures of bosons and fermions in deep optical lattices [Best \emph{et al.}, PRL \textbf{102}, 030408 (2009); Will \emph{et al.}, Nature \textbf{465}, 197 (2010)]. In the present work, we derive an effective lowest-band Hamiltonian in 3D that generalizes the standard Bose-Fermi Hubbard model taking these effects as well as nonlinear corrections of the tunneling amplitudes mediated by interspecies interactions into account. It is shown that a correct description of the lattice states in terms of the bare-lattice Wannier functions rather than approximations such as harmonic oscillator states is essential. In contrast to self-consistent approaches based on effective Wannier functions our approach provides a quantitative explanation of the observed reduction of the superfluid phase for repulsive interspecies interactions.

description: This report presents the efforts of leaders in Virginia to learn more about teachers’ experience with children who demonstrate challenging behavior in center-based and home-based ECE settings. These leaders partnered with the National Center for Children in Poverty (NCCP) to design and implement a survey of Virginia’s ECE teachers that serve infants, toddlers, and preschoolers. The survey and analysis of responses examined the following questions: How common are different types of challenging behavior? How many children with challenging behavior, in different age groups, do teachers have in their classrooms or child care homes in the course of a year? What are the consequences of challenging behavior, and how often does removal from the ECE setting occur? What are the family circumstances of children with challenging behavior? How do teachers address challenging behavior and what barriers do they face? What factors contribute to the incidence of children with challenging behavior and removal from programs? What supports do teachers believe will help them address the needs of children with challenging behavior?
Lagrangian spheres, symplectic surfaces and the symplectic mapping class group

Subjects: subject: Symplectic Geometry (math.SG)

description: Given a Lagrangian sphere in a symplectic 4-manifold $(M, ω)$ with $b^+=1$, we find embedded symplectic surfaces intersecting it minimally. When the Kodaira dimension $κ$ of $(M, ω)$ is $-\infty$, this minimal intersection property turns out to be very powerful for both the uniqueness and existence problems of Lagrangian spheres. On the uniqueness side, for a symplectic rational manifold and any class which is not characteristic and ternary, we show that homologous Lagrangian spheres are smoothly isotopic, and when the Euler number is less than 8, we generalize Hind and Evans' Hamiltonian uniqueness in the monotone case. On the existence side, when $κ=-\infty$, we give a characterization of classes represented by Lagrangian spheres, which enables us to describe the non-Torelli part of the symplectic mapping class group.

The generality of our approach permits us to investigate flavor oscillation in exotic parameter regimes, and present the corresponding oscillation formulae.

description: The naming game (NG) describes the agreement dynamics of a population of agents that interact locally in a pairwise fashion, and in recent years statistical physics tools and techniques have greatly contributed to shed light on its rich phenomenology. Here we investigate in details the role played by the way in which the two agents update their states after an interaction. We show that slightly modifying the NG rules in terms of which agent performs the update in given circumstances (i.e. after a success) can either alter dramatically the overall dynamics or leave it qualitatively unchanged. We understand analytically the first case by casting the model in the broader framework of a generalized NG. As for the second case, on the other hand, we note that the modified rule reproducing the main features of the usual NG corresponds in fact to a simplification of it consisting in the elimination of feedback between the agents. This allows us to introduce and study a very natural broadcasting scheme on networks that can be potentially relevant for different applications, such as the design and implementation of autonomous sensor networks, as pointed out in the recent literature.

description: Equal-mass two-component Fermi gases under spherically symmetric external harmonic confinement with large s-wave scattering length are considered. Using the stochastic variational approach, we determine the lowest 286 and 164 relative eigenenergies of the (2,2) and (3,1) systems at unitarity as a function of the range $r_0$ of the underlying two-body potential and extrapolate to the $r_0 \rightarrow 0$ limit. Our calculations include all states with vanishing and finite angular momentum $L$ (and natural and unnatural parity $Π$) with relative energy up to $10.5 \hbar Ω$, where $Ω$ denotes the angular trapping frequency of the external confinement. Our extrapolated zero-range energies are estimated to have uncertainties of 0.1% or smaller. The (2,2) and (3,1) energies are used to determine the fourth-order virial coefficient of the trapped unitary two-component Fermi gas in the low-temperature regime. Our results are compared with recent predictions for the fourth-order virial coefficient of the homogeneous system. We also calculate small portions of the energy spectra of the (3,2) and (4,1) systems at unitarity.

Poverty and Brain Development in Early Childhood

description: Researchers have gathered new evidence on the importance of the first years of life for children’s emotional and intellectual development. Unfortunately, millions of American children are poor during these crucial years. More than one in five of America’s children under age three lived in poverty in 1997. These 2.5 million poor children face a greater risk of impaired brain development due to their exposure to a number of risk factors associated with poverty. Many poor young children are resilient and able to overcome tremendous obstacles but poverty poses serious threats to children’s brain development. Recent advances in the study of brain development show a sensitive period when the brain is most able to respond to and grow from exposure to environmental stimulation. This window of optimal brain development is from the prenatal period to the first years of a child’s life. While all children are potentially vulnerable to a number of risk factors which can impede brain development during this sensitive period, a disproportionate number of children in poverty are actually exposed to such risk factors. These risk factors can influence the brain through multiple pathways.

description: We study a supersymmetric model for strongly interacting lattice fermions in the presence of a staggering parameter. The staggering is introduced as a tunable parameter in the manifestly supersymmetric Hamiltonian. We obtain analytic expressions for the ground states in the limit of small and large staggering for the model on the class of doubly decorated lattices. On this type of lattice there are two ground states, each with a different density. In one limit we find these ground states to be a simple Wigner crystal and a valence bond solid (VBS) state. In the other limit we find two types of quantum liquids. As a special case, we investigate the quantum liquid state on the one dimensional chain in detail. It is characterized by a massless kink that separates two types of order.

Infants--Mental health services

description: There is now substantial evidence that young children’s mental health plays a critical role in their early learning and school readiness, long-term school success and self-sufficiency, and future health and mental health outcomes. Fortunately, many states are working to strengthen supports for infants’ and young children’s mental health. This brief examines states’ Medicaid coverage for key infant and early childhood mental health (IECMH) services, along with policies that contribute to service access and quality. It presents the results of an updated 50-state survey that gathered information from state administrators about Medicaid coverage and policies related to the following services for children from birth to age 6: Child screening for social-emotional problems; Maternal depression screening in pediatric and family medicine settings; Developmentally appropriate diagnosis using DC:0–5; Family navigators to help families access services; Mental health services in pediatric, child care and early education, and home settings; Dyadic (parent-child) treatment; Parenting programs to address child mental health needs
Universality of scaling and multiscaling in turbulent symmetric binary fluids

description: We elucidate the universal scaling and multiscaling properties of the nonequilibrium steady states (NESS) in a driven symmetric binary fluid (SBF) mixture in its homogeneous miscible phase in three dimensions (3d). We show, for the first time, via Direct Numerical Simulations (DNS) that structure functions of the velocity and the concentration gradient exhibit multiscaling in 3d and extended self-similarity (ESS). We also find that, in contrast to the well-known passive scalar turbulence problem, structure functions of the concentration show simple scaling. We propose a new shell model for SBF turbulence which preserve all the invariances in the ideal limit of the SBF equations and which reduces to a well-known shell model for fluid turbulence in the zero concentration field limit. We show that the shell model has the same scaling properties as the 3d SBF equations. Our combined results from our DNS of the SBF equations and shell-model studies consistently bring out the multiscaling of the velocity and concentration gradient fields and simple scaling of the concentration field.

description: The early childhood field has known for decades that the quality of a child’s early experience has a great impact on his or her growth and development. Recent research confirms that at no time in a child’s life is the nature of the environment, and especially the earliest relationships, more crucial than during the infant and toddler years. At the same time, there is also increasing pressure for mothers with very young children to work. Thus, those responsible for policy and program efforts for babies and their families face a significant challenge: simultaneously providing healthy environments for infants and toddlers, promoting strong parent-child relationships, and supporting parents’ ability to work. This issue brief explores emerging efforts that aim to meet the needs of infants and toddlers in low-income families by: (1) addressing access and quality issues related to child care for infants and toddlers and (2) stimulating strong and nurturing parent-child relationships, while at the same time supporting lowincome parents with babies (both infants and toddlers) who are currently in the workforce or who are moving into the workforce. (Although child health and nutrition are also very important, this issue brief does not address these topics.) Specifically, the brief identifies the policy and program implications of the special needs of this age group. It describes opportunities and barriers presented by current policy and programs related to child care, early childhood development, and welfare reform. The issue brief outlines some approaches being explored by programs, communities, and states to assist families in ways that take into account families’ needs, preferences, and working lives. It ends with a discussion of five key approaches to promoting the healthy development of infants and toddlers in the context of promoting family economic security.

description: A study of the substructure of jets with transverse momentum greater than 400 GeV/c produced in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV at the Fermilab Tevatron Collider and recorded by the CDF II detector is presented. The distributions of the jet mass, angularity, and planar flow are measured for the first time in a sample with an integrated luminosity of 5.95 fb^-1. The observed substructure for high mass jets is consistent with predictions from perturbative quantum chromodynamics.

Extreme value distributions for weakly correlated fitnesses in block model

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study the limit distribution of the largest fitness for two models of weakly correlated and identically distributed random fitnesses. The correlated fitness is given by a linear combination of a fixed number of independent random variables drawn from a common parent distribution. We find that for certain class of parent distributions, the extreme value distribution for correlated random variables can be related either to one of the known limit laws for independent variables or the parent distribution itself. For other cases, new limiting distributions appear. The conditions under which these results hold are identified.
