description: The merger of two neutron stars produces an outflow of radioactive heavy nuclei. Within a second of merger, the central remnant is expected to also launch a relativistic jet, which shock-heats and disrupts a portion of the radioactive ejecta. Within a few hours, emission from the radioactive material gives rise to an ultraviolet, optical, and infrared transient (a kilonova). We use the endstates of a suite of 2D relativistic hydrodynamic simulations of jet-ejecta interaction as initial conditions for multi-dimensional Monte Carlo radiation transport simulations of the resulting viewing angle-dependent light curves and spectra starting at 1.5h after merger. We find that on this timescale, jet shock heating does not affect the kilonova emission. However, the jet disruption to the density structure of the ejecta does change the light curves. The jet carves a channel into the otherwise spheroidal ejecta, revealing the hot, inner regions. As seen from near ($\lesssim 30 °$) the jet axis, the kilonova is brighter by a factor of a few and bluer. The strength of this effect depends on the jet parameters, since the light curves of more heavily disrupted ejecta are more strongly affected. The light curves and spectra are also more heavily modified in the ultraviolet than in the optical.

description: Magnetic properties of the silver vanadium phosphate Ag(2)VOP(2)O(7) are studied by means of magnetic susceptibility measurements and electronic structure calculations. In spite of the layered crystal structure suggesting 1D or 2D magnetic behavior, this compound can be understood as a spin dimer system. The fit of the magnetic susceptibility indicates an intradimer interaction of about 30 K in perfect agreement with the computational results. Our study emphasizes the possible pitfalls in interpreting experimental data on structural basis only and points out the importance of microscopic models for the understanding of the magnetic properties of vanadium phosphates.

description: We find unusual temperature dependence of the ferromagnetic resonance (FMR) frequency $f_{\rm R}$ for the spin-reorientation (SR) transition, in which the easy axis changes depending on temperature, observed in the Nd permanent magnet, Nd$_2$Fe$_{14}$B: $f_{\rm R} \sim 0$ below the SR transition temperature ($T_{\rm R}$), drastic increase of $f_{\rm R}$ around $T_{\rm R}$, and decrease from a peak at higher temperatures. It is nontrivial that the SR transition causes the unusual behavior of the FMR frequency in a wide temperature region. We show the mechanism of the temperature dependence by theoretical and computational analyses. We derive a general relation between $f_{\rm R}$ and magnetizations to help the understanding of the mechanism, and clarify that the fluctuation of the transverse magnetization is a key ingredient for the resonance in all temperature regions.

description: We investigate the Cauchy problem for a class of nonlinear elliptic operators with $C^\infty$-coefficients at a regular set $Ω\subset R^n$. The Cauchy data are given at a manifold $Γ\subset \partialΩ$ and our goal is to reconstruct the trace of the $H^1(Ω)$ solution of a nonlinear elliptic equation at $\partial Ω/ Γ$. We propose two iterative methods based on the segmenting Mann iteration applied to fixed point equations, which are closely related to the original problem. The first approach consists in obtaining a corresponding linear Cauchy problem and analyzing a linear fixed point equation; a convergence proof is given and convergence rates are obtained. On the second approach a nonlinear fixed point equation is considered and a fully nonlinear iterative method is investigated; some preliminary convergence results are proven and a numerical analysis is provided.

description: The magnetic susceptibility of the one-dimensional Hubbard model with open boundary conditions at arbitrary filling is obtained from field theory at low temperatures and small magnetic fields, including leading and next-leading orders. Logarithmic contributions to the bulk part are identified as well as algebraic-logarithmic divergences in the boundary contribution. As a manifestation of spin-charge separation, the result for the boundary part at low energies turns out to be independent of filling and interaction strength and identical to the result for the Heisenberg model. For the bulk part at zero temperature, the scale in the logarithms is determined exactly from the Bethe ansatz. At finite temperature, the susceptibility profile as well as the Friedel oscillations in the magnetisation are obtained numerically from the density-matrix renormalisation group applied to transfer matrices. Agreement is found with an exact asymptotic expansion of the relevant correlation function.

description: This qualitative research study explored the perceptions of African American baccalaureate nursing students as they prepared for and completed their NCLEX-RN examination experiences. Thirteen study participants were included in this inquiry. Four informants participated in the one-time focus group session and the remaining nine informants participated in the individual interviews. Two dominant themes were identified through the informants' perspectives:  1) Professional entry into practice, and 2) Achievement of personal goals. Five supporting themes were also identified and included:  1) The preparation process for the NCLEX-RN examination; 2) Mentoring and the importance of minority faculty presence; 3) Family support throughout nursing education and the NCLEX-RN experience; 4) Spirituality; and 5) Race and persistence. The informants identified the NCLEX-RN examination experience as a requirement necessary to gain entry to professional practice and viewed it as a means to an end. Their responses suggested that the NCLEX-RN examination required both individualized and customized approaches to address the needs of the test candidates.

description: Two biological antioxidant capacity assays, based on a reactive oxygen species inducible E. coli strain, were described.  The strain harbored fusion genes sodA::gfp, and these genes measure oxidative stress by quantitatively responding to superoxide anions.  The system measures ascorbate and Trolox antioxidant capacity in response to free radical generation by paraquat.  Antioxidant capacity was measured by the degree of inhibition of induced fluorescence.  At a fixed oxidant concentration, specific fluorescence decreased as the concentration of the antioxidant increased.  Both assays were validated for their reproducibility of the calibration curves, their precision and their accuracy.  In both assays, the limit of detection and the limit of quantitation were 2.50mM and 5.00mM, respectively.  The hydrophilic antioxidant capacity assay was also correlated with the currently used standard assays, ORAC (r = 0.981) and DPPH assays (r = 0.841).  By utilizing the autofluorescent green fluorescent protein (GFP) as the reporter gene and a multi-well plate reader as the screening tool, the method was noninvasive and cost effective.  Compared to other available antioxidant capacity assays, most of which need further dilution of the test samples, this assay is one of the few assays that is able to assess samples with high antioxidant concentrations.  Furthermore, since living cells are employed, actual bio-availability is assessed. The hydrophilic antioxidant capacity assay was also utilized to compare antioxidant capacity in common teas, wines and juices.  Different processing methods of foods, coffees with different roasting levels and different nutritional supplements were investigated for their effects on antioxidant capacity as well.

description: A wide range of techniques have been developed to search for particle dark matter, including direct detection, indirect detection, and collider searches. The prospects for the detection of neutralino dark matter is quite promising for each of these three very different methods. Looking ahead to a time in which these techniques have successfully detected neutralino dark matter, we explore the ability of these observations to determine the parameters of supersymmetry. In particular, we focus on the ability of direct and indirect detection techniques to measure the parameters $μ$ and $m_A$. We find that $μ$ can be much more tightly constrained if astrophysical measurements are considered than by LHC data alone. In supersymmetric models within the $A$-funnel region of parameter space, we find that astrophysical measurements can determine $m_A$ to roughly $\pm100$ GeV precision.

description: This study sought to evaluate the effectiveness of virtual reality (VR) videogame distraction for children experiencing acute pain and clarify the role of coping style and pain coping strategies as moderators of VR distraction effectiveness.  Sixty-two children (6-13 years old) underwent a baseline cold pressor trial followed by two cold pressor trials in which interactive videogame distraction was delivered with or without a VR helmet in counterbalanced order.  As predicted, children demonstrated significant improvement in pain tolerance during both distraction conditions.  However, there were no differences in pain tolerance between the distraction conditions.  Neither coping style nor pain coping strategies moderated children's responses to distraction.  Distraction was effective for both avoiders and approachers.

description: Surveys have shown radio-loud (RL) quasars constitute $10 \%$-$15 \%$ of the total quasar population. However, it is unknown if the radio-loud fraction (RL quasars/Total quasars) remains consistent among different parameter spaces. This study shows that radio-loud fraction increases for increasing full width half maximum (FWHM) velocity of the H$β$ and MgII broad emission line. Our data has been obtained from Shen et al. (2011) catalogue. To investigate the reason, in this preliminary study we analyse various properties like bolometric luminosity, optical continuum luminosity, black hole (BH) mass and accretion rate of RL quasars and RQ quasars sample which have FWHM greater than 15000km/s (High broad line). From the distributions we can conclude for all the properties in high broad line, RL quasars are having higher values than RQ quasars. We have predicted RL quasars are intrinsically brighter than RQ quasars and also predicted BH mass-jet connection and accretion disk-jet connection from our results but to conclude anything more analysis is needed.

description: The nonperturbative nature of nucleon-nucleon interactions as a function of a momentum cutoff is studied using Weinberg eigenvalues as a diagnostic. This investigation extends an earlier study of the perturbative convergence of the Born series to partial waves beyond the 3S1-3D1 channel and to positive energies. As the cutoff is lowered using renormalization-group or model-space techniques, the evolution of nonperturbative features at large cutoffs from strong short-range repulsion and the iterated tensor interaction are monitored via the complex Weinberg eigenvalues. When all eigenvalues lie within the unit circle, the expansion of the scattering amplitude in terms of the interaction is perturbative, with the magnitude of the largest eigenvalue setting the rate of convergence. Major decreases in the magnitudes of repulsive eigenvalues are observed as the Argonne v18, CD-Bonn or Nijmegen potentials are evolved to low momentum, even though two-body observables are unchanged. For chiral EFT potentials, running the cutoff lower tames the impact of the tensor force and of new nonperturbative features entering at N3LO. The efficacy of separable approximations to nuclear interactions derived from the Weinberg analysis is studied as a function of cutoff, and the connection to inverse scattering is demonstrated.

SBMH

description: A number of trends in adolescent health have increased the importance of mental health services.  In 1999, there were about 21 percent of children and adolescents between the ages of 9 and 17 that had a diagnosable mental disorder, causing some functional impairment (US DHHS, 1999).  School based mental health (SBMH) has been reported to increase access to services (Armbruster, Gerstein & Fallon, 1997, Weist & Albus, 2004).  Seventy-five percent of children who have mental health problems do not receive care (Kataoka, Zhang & Wells, 2002).  Of those that receive care, 75 percent receive care from within the school (Burns, et al, 1995).   ""SBMH services offer promise in the effort to bridge the gap between service need and service utilization by providing access to underserved populations""(Armbruster & Lichtman, 1999, p.493).  However, states vary in their ability to provide services to children in school based mental health settings. This study conducted interviews with participants in nine states that are establishing connections between schools and mental health systems.  Information gathered from these states was then used to seek opinions and perceptions of other State Mental Health Directors for Children. The model for this study combined the works of Rogers (1995), Berry and Berry (1990) and Mintrom and Vergari (1998) to examine the factors that influence the diffusion of innovation. The qualitative piece of this research identifies prominent necessities in an innovative SBMH program, factors that facilitate SBMH programs and barriers to innovative SBMH programs.  The questionnaires that were sent to each of the state Directors also provided data on perceptions of SBMH innovations. The multivariate analyses included twenty programmatic measures and two per capita spending measures of readiness for innovation in SBMH.  The models that were estimated revealed that state resources matter.  The professionalism measure also showed a positive association. Bivariate analyses between measures of innovation and Census Divisions revealed some positive associations.  The political variables did not show any associations with measures of readiness for innovation in the models.

description: In the Great Plains, playas are critical wetland habitats for migratory birds and a source of recharge for the agriculturally-important High Plains aquifer. The temporary wetlands exhibit complex hydrology, filling rapidly via local rain storms and then drying through evaporation and groundwater infiltration. Using a long short-term memory (LSTM) neural network to account for these complex processes, we modeled playa inundation for 71,842 playas in the Great Plains from 1984-2018. At the level of individual playas, the model achieved an F1-score of 0.538 on a withheld test set, displaying the ability to predict complex inundation patterns. When averaging over all the playas in the entire region, the model is able to very closely track inundation trends, even during periods of drought. Our results demonstrate potential for using LSTMs to model complex hydrological dynamics. Our modeling approach could be used to model playa inundation into the future under different climate scenarios to better understand how wetland habitats and groundwater will be impacted by changing climate.

Burden of Child Support and the Likelihood of Collection: An Empirical Examination

description: One important consideration in making a determination on what is an appropriate order amount for child support is the likelihood for collection, since the right order amount is useless if it does not result in real money being transferred to the child. This is the focus of my dissertation research. I use administrative data for a sample of child support orders established in Maryland between 2002 and 2006 (n=3,687) to investigate my central research question, which is whether and how obligor burden level and the child support collection rate are related. I model the relationship using Ordinary Least Squares (OLS) to estimate a multivariate linear regression, controlling for a variety of descriptive characteristics both at the baseline and during a 3-year follow up period.  My results confirm that an obligor's child support burden level and collection rate are negatively related and statistically significant. Importantly, the magnitude of the relationship is relatively small (though not insubstantial) once other factors are controlled for, so adjusting the burden level is not likely to generate large increases in the collection rate overall. In addition, I find that the negative relationship between burden level and collection rates exists across a range of incomes and order amounts, which may be unique to states using an income shares guidelines approach. Finally, I find that the relationship is nonlinear and that the impact of burden level on the collection rate is stronger for those with a higher burden level, indicating a possible threshold beyond which orders are less likely to result in collections. The final section of the dissertation includes an large-scale application of my results, which shows modest increases in the collection rate broadly defined if order amounts are capped at a particular burden level (i.e. 20 or 30 percent of an obligor's income). However, the impact could be dramatic for individual cases and obligors, if the reduction motivates increases in compliance and prevents the accumulation of arrears in the long-term, even if the total amount collected is slightly less in the short-run.

description: Background:  Human immunodeficiency virus (HIV) remains a major public health problem in the United States. It is estimated that one in five Americans with HIV are unaware that they are infected. Populations with addictive disorders are disproportionately impacted by HIV. While the importance of conducting on-site HIV testing as part of substance abuse treatment has long been recognized, research shows that many programs do not offer this service.  Aims: The current study examines the role of specific organizational, community, and policy factors in shaping the availability of on-site HIV testing in U.S. substance abuse treatment facilities.  Methods:  This study uses a project-specific dataset that draws from several complementary data sources, including the National Survey of Substance Abuse Treatment Services (N-SSATS), the American Community Survey, the Kaiser Family Foundation, and the peer-reviewed literature. Hypothesized relationships at the organizational, county, and state levels are tested using a multilevel logistic regression modeling approach.  Results: This study identifies a number of factors associated with substance abuse treatment organizations' adoption of on-site HIV testing, including public ownership/operation, county-level demographics (proportion of the population that is African American or Hispanic), and policies requiring allocation of substance abuse block grants towards HIV prevention. Adoption of HIV testing did not differ based on organizations' receipt of direct public funding, county economic characteristics, state HIV testing statutes, or state-level public expenditures on substance abuse treatment or HIV prevention.  Conclusions:  Adoption of HIV testing in substance abuse treatment programs is influenced by a complex web of organizational, community, and state characteristics. The patterning of treatment organizations' adoption of on-site HIV testing holds potential implications for facilitating diffusion of this evidence-based public health technology throughout the substance abuse treatment system.

description: The growing foreclosure crisis has brought to light the problems of subprime and predatory lending.  These problems include the potential for lost equity, foreclosure of homes, and the targeting of vulnerable populations.  Beginning in 1999, states began passing legislation designed to limit predatory lending.  However, much is still unknown about the impacts of these laws.   In this study I expand the growing literature on the impacts of state anti-predatory lending laws by addressing the impacts in unique ways.  I examined the impact on populations typically targeted for predatory loans that have not been part of previous studies.  Another unique aspect of my study was my focus on whether the impacts of state anti-predatory lending laws change over time in an attempt to understand whether lenders learn to compensate for these laws.  I used data collected under the Home Mortgage Disclosure Act (HMDA) from 1997 to 2002 to examine the impacts of state anti-predatory lending legislation.  I examined these impacts through descriptive statistics and logistic regressions.    I found that state anti-predatory lending laws have little meaningful impact on the likelihood of receiving a subprime loan.  Despite the limited overall impact, I found a substantial impact when examining refinance and home purchase loans separately.  As a result, I concluded that state anti-predatory lending laws may reduce those loans most likely to be predatory.  Some populations, particularly minority borrowers, had the impact I expected of a reduced likelihood of receiving subprime loans.  This was also evident among subprime refinance loans relative to home purchase loans.  This may indicate a potential reduction in the targeting of predatory loans to vulnerable borrower populations.  However, to the extent that this reduction occurs, it appears to be limited to only a few groups.  I also found few results that imply lenders learn to compensate for these laws over time.  Finally, I discovered that the impacts of state anti-predatory lending legislation are sensitive to the definition of subprime loans and model specification.

description: Increasing numbers of nursing home residents are working-aged individuals between the ages of 18 and 64 years. Though there are several plausible explanations, it is unclear why working-aged adults are entering nursing homes in greater numbers. Recent data indicate that the prevalence of chronic disease and disability are increasing among working-aged adults. Combined, these trends may contribute to increased utilization of nursing home care. In addition to these factors, a lack of family and social supports may also contribute to increased use of nursing home care. One of the goals of this research is to determine the relationships between these variables and length of stay among working-aged nursing home residents. Further, increased nursing home use among this population is occurring within a post-Olmstead policy environment. According to the precedent set by the Supreme Court in 1999 in Olmstead v. L.C., individuals with disabilities are not to be indiscriminately placed in institutional settings when they are able and express a preference to live in the community. In other words, states are legally required to provide individuals with disabilities with access to community-based settings where appropriate and within the state's resources. The purpose of this research is to determine the strength and direction of the relationships between length of stay and other variables among working-aged adults in nursing homes. To examine these trends, this study utilizes data from the National Nursing Home Survey (NNHS), survey years 1985 through 2004. Length of stay has fiscal and programmatic ramifications for the Medicaid program, as individuals with nursing home longer stays are more likely to transition to Medicaid. Additional policy implications relate to transition programs for adults already in nursing homes who may be better served in the community and home and community-based services for adults without familial and social supports. Lastly, this study suggests the need for policy interventions to improve the Medicaid program to ensure that working-aged adults with disabilities have viable options for accessing services. This study adds to the existing body of research, because it 1) creates a profile of working-aged individuals entering nursing homes, 2) examines if this profile has changed between 1985 and 2004 using National Nursing Home Survey data, 3) determines the variables that have the greatest impact on length of stay, 4) estimates the relationship between discharge location and length of stay among discharge residents, and 5) examines the resulting policy implications for the Medicaid program.

description: We model the gas and dust dynamics in a turbulent protoplanetary disc undergoing extreme-UV photoevaporation in order to better characterise the dust properties in thermal winds (e.g. size distribution, flux rate, trajectories). Our semi-analytic approach allows us to rapidly calculate these dust properties without resorting to expensive hydrodynamic simulations. We find that photoevaporation creates a vertical gas flow within the disc that assists turbulence in supplying dust to the ionisation front. We examine both the delivery of dust to the ionisation front and its subsequent entrainment in the overlying wind. We derive a simple analytic criterion for the maximum grain size that can be entrained and show that this is in good agreement with the results of previous simulations where photoevaporation is driven by a range of radiation types. We show that, in contrast to the case for magnetically driven winds, we do not expect large scale dust transport within the disc to be effected by photoevaporation. We also show that the maximum size of grains that can be entrained in the wind ($s_{\rm max}$) is around an order of magnitude larger than the maximum size of grains that can be delivered to the front by advection alone ($s_{\rm crit} \lesssim 1$ $μ{\rm m}$ for Herbig Ae/Be stars and $\lesssim 0.01$ $μ{\rm m}$ for T Tauri stars). We further investigate how larger grains, up to a limiting size $s_{\rm limit}$, can be delivered to the front by turbulent diffusion alone. In all cases, we find $s_{\rm max} \gtrsim s_{\rm limit}$ so that we expect that any dust that is delivered to the front can be entrained in the wind and that most entrained dust follows trajectories close to that of the gas.

description: We study the systems of scalar and spinor particles with mixing emitted by external classical sources. The particles wave functions exactly accounting for external sources are obtained directly from the Lorentz invariant wave equations in (3+1)-dimensional space-time. Then we discuss sources which are localized in space and emit harmonic radiation. We obtain that the considered scalar and spinor fields can be converted from one type to another due to the presence of the vacuum mixing. This phenomenon is shown to be analogous to neutrino flavor oscillations in vacuum since the calculated transition and survival probabilities coincide with the corresponding expressions for neutrino oscillations. When we discuss the evolution of spinor particles, the situation of general mass matrix, which has both Dirac and Majorana mass terms, is studied. In this case we analyze the appearance of antiparticles in the initial particles beam. The relevance of the developed technique to the description of neutrino flavor oscillations is examined.

description: A concept of an electrically tunable resonance detector of THz-frequency signals based on antiferromagnetic/heavy metal (AFM/HM) hetero-structure is proposed. The conversion of a THz-frequency input signal into DC voltage is done using the inverse spin Hall effect in an (AFM/HM) bilayer. An additional bias DC current in the HM layer can be used to vary the effective anisotropy of the AFM, and, therefore, to tune the AFMR frequency. The proposed AFM/HM hetero-structure works as a resonance-type quadratic detector which can be tuned by the bias current in the range of at least 10 percent of the AFMR frequency and our estimations show that the sensitivity of this detector could be comparable to that of modern detectors based on the Schottky, Gunn or graphene-based diodes.

description: Software engineering educators are continually challenged by rapidly evolving concepts, technologies, and industry demands. Due to the omnipresence of software in a digitalized society, higher education institutions (HEIs) have to educate the students such that they learn how to learn, and that they are equipped with a profound basic knowledge and with latest knowledge about modern software and system development. Since industry demands change constantly, HEIs are challenged in meeting such current and future demands in a timely manner. This paper analyzes the current state of practice in software engineering education. Specifically, we want to compare contemporary education with industrial practice to understand if frameworks, methods and practices for software and system development taught at HEIs reflect industrial practice. For this, we conducted an online survey and collected information about 67 software engineering courses. Our findings show that development approaches taught at HEIs quite closely reflect industrial practice. We also found that the choice of what process to teach is sometimes driven by the wish to make a course successful. Especially when this happens for project courses, it could be beneficial to put more emphasis on building learning sequences with other courses.

description: We revisit the uniaxially strained graphene immersed in a uniform homogeneous magnetic field orthogonal to the layer in order to describe the time evolution of coherent states build from a semi-classical model. We consider the symmetric gauge vector potential to render the magnetic field, and we encode the tensile and compression deformations on an anisotropy parameter $ζ$. After solving the Dirac-like equation with an anisotropic Fermi velocity, we define a set of matrix ladder operators and construct electron coherent states as eigenstates of a matrix annihilation operator with complex eigenvalues. Through the corresponding probability density, we are able to study the anisotropy effects on these states on the $xy$-plane as well as their time evolution. Our results show clearly that the quasi-period of electron coherent states is affected by the uniaxial strain.

Seed dispersal, seed attributes and edaphic factors : their role and impact on the regeneration of antelope bitterbrush (purshia tridentata, rosaceae)

description: The purpose of this research was to collect detailed demographic information concerning the early life stages of antelope bitterbrush Purshia tridentata and elucidate those biotic and abiotic factors limiting or enhancing seed dispersal, seedling emergence and survival. Agricultural and urban development have seriously reduced the size and continuity of natural areas in the Okanagan valley, British Columbia. Antelope bitterbrush has its most northern distribution in this setting and this study was initiated to address questions concerning the ability of this shrub to persist in the face of rapid change. The research was undertaken in three parts represented by the separate chapters of this manuscript; Chapter 1 a survey of juvenile plants, Chapter 2 a seed removal experiment and Chapter 3 a reciprocal planting experiment. In 1994 I estimated the density of juvenile Purshia shrubs at ten separate sites. This indicated significant variation in seedling establishment between sites and provided the basis for 2 separate lines of research. First, I placed Purshia seeds into the field at feeding stations to determine what class of seed eating animals, insects, birds or rodents, were responsible for seed predation. Seed predation was mostly due to nocturnal rodents some of which, through caching behaviour, also acted as effective agents of seed dispersal. Secondly, 8,000 seeds were planted individually 2.25 cm beneath the soil surface. Environmental factors explained 40 % of the variation in seedling emergence while variation between maternal families accounted for 16 %. Seedling emergence correlated negatively with silt content of soils and positively with moss cover. Shrubs that on average produced seeds with a higher nitrogen content also produced seeds that were less likely to emerge. In silty soils initial seedling emergence appeared to be limited by crusting at the soil surface. However, soils with higher silt content contained more seedlings at the end of the first year, presumably due to greater moisture availability. The correlation between moss cover and seedling emergence provides some evidence that cryptogamic crusts confer conditions favourable to seedling establishment. Knowledge of factors limiting seedling establishment is required to manage and where appropriate to restore Purshia shrubs in the highly impacted landscape of the south Okanagan valley.
