The Effect of Peanut/Tree Nut Allergy on Perceived Parental Overprotection and Young Adult Autonomy, Anxiety, Depression, and Self-Esteem
Creators: name: Jones, Linda
Publisher: name: Maryland Shared Open Access Repository
Year: 2007
Subjects: Psychology, Clinical (0622)

description: The prevalence of childhood peanut/tree nut allergy has increased rapidly over the last several decades. The primary goals of this study were to examine how young adults with peanut and/or tree nut allergy perceived parental characteristics compared to healthy young adults and to determine if these two groups self-reported differences in autonomy, anxiety, depression, and self-esteem. Fifty-five peanut/tree nut allergic participants and 344 healthy participants between the ages of 18 and 22 were recruited through internet college forums and food allergy support groups to complete an online survey. Results indicated that peanut/tree nut allergic participants reported fewer social self-confidence concerns than healthy participants, but the samples did not differ with respect to other variables of interest. Further analyses revealed that food allergic participants with a perceived history of anaphylaxis rated their parents as more overprotective than food allergic participants without a perceived history of anaphylaxis. These findings were not evident when based on physical indicators of anaphylaxis. Additionally, perceived risk of allergen exposure was related to higher ratings of anxiety and depression. As a group, peanut/tree nut allergic young adults did not differ from healthy young adults. However, perception of allergy severity may be a reliable indicator of food allergic individuals who are at risk for psychological distress. Further research to replicate and expand on these findings is warranted.
A Mann iterative regularization method for elliptic Cauchy problems

description: We investigate the Cauchy problem for linear elliptic operators with $C^\infty$-coefficients at a regular set $Ω\subset R^2$, which is a classical example of an ill-posed problem. The Cauchy data are given at the manifold $Γ\subset \partialΩ$ and our goal is to reconstruct the trace of the $H^1(Ω)$ solution of an elliptic equation at $\partial Ω/ Γ$. The method proposed here composes the segmenting Mann iteration with a fixed point equation associated with the elliptic Cauchy problem. Our algorithm generalizes the iterative method developed by Maz'ya et al., who proposed a method based on solving successive well-posed mixed boundary value problems. We analyze the regularizing and convergence properties both theoretically and numerically.

description: We have extended our model for charged current neutrino-nucleus interactions to neutral current reactions. For the elementary neutrino-nucleon interaction, we take into account quasielastic scattering, Delta excitation and the excitation of the resonances in the second resonance region. Our model for the neutrino-nucleus collisions includes in-medium effects such as Fermi motion, Pauli blocking, nuclear binding, and final-state interactions. They are implemented by means of the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) coupled-channel transport model. This allows us to study exclusive channels, namely pion production and nucleon knockout. We find that final-state interactions modify considerably the distributions through rescattering, charge-exchange and absorption. Side-feeding induced by charge-exchange scattering is important in both cases. In the case of pions, there is a strong absorption associated with the in-medium pionless decay modes of the Delta, while nucleon knockout exhibits a considerable enhancement of low energy nucleons due to rescattering. At neutrino energies above 1 GeV, we also obtain that the contribution to nucleon knockout from Delta excitation is comparable to that from quasielastic scattering.

description: Imaging and spectroscopy of the knots, clumps, and extended arcs in the complex ejecta of VY CMa confirm a record of high mass loss events over the past few hundred years. HST/STIS spectroscopy of numerous small knots close to the star allow us to measure their radial velocities from the strong K I emission and determine their separate motions, spatial orientations, and time since ejecta. Their ages concentrate around 70, 120, 200 and 250 years ago. A K I emission knot only 50 mas from the star ejected as recently as 1985 -- 1995 may coincide with an H2O maser. Comparison with VY CMa's historic light curve from 1800 to the present, shows several knots with ejection times that correspond with extended periods of variability and deep minima. The similarity of this correspondence in VY CMa with the remarkable recent dimming of Betelgeuse and an outflow of gas is apparent. The evidence for similar outflows from the surface of a more typical red supergiant suggests that discrete ejections are more common and surface or convective activity is a major source of mass loss for red supergiants.

description: Very recently, motivated by the result of Bhatia and Šemrl which characterizes the Birkhoff-James orthogonality of operators on a finite dimensional Hilbert space in terms of norm attaining points, the Bhatia-Šemrl property was introduced. The main purpose of this article is to study the denseness of the set of multilinear maps with the Bhatia-Šemrl property which is contained in the set of norm attaining ones. Contrary to the most of previous results which were shown for operators on real Banach spaces, we prove the denseness for multilinear maps on some complex Banach spaces. We also show that the denseness of operators does not hold when the domain space is $c_0$ for arbitrary range. Moreover, we find plenty of Banach spaces $Y$ such that only the zero operator has the Bhatia-Šemrl property in the space of operators from $c_0$ to $Y$.

The corresponding lower bounds on distillable entanglement are provided. We also present a simple alternative proof that for any bipartite quantum state entanglement cost is an upper bound on distillable cryptographic key in bipartite scenario.

description: Parent-teacher communication is an important aspect of parental involvement in education. Research suggests that because Hispanic immigrant parents encounter communication barriers, they tend to be less involved at school than other parents. Currently there are no instruments that measure communication barriers. The present study developed a questionnaire, The Communication Questionnaire, designed to measure communication barriers and examined aspects of construct validity. A literature review and feedback from professionals support aspects of content validity. Cognitive interviews provide evidence that support aspects of substantive validity: questionnaire items were interpreted as intended. Cronbach's alpha supports aspects of structural validity: high internal consistency was observed. Aspects of external validity were supported: there was a moderate correlation with a related measure and a weak correlation with an unrelated measure. These results provide evidence for the validity of the use of the scores on The Communication Questionnaire.

description: The use of glucose as a source in biofuel cell technology has received a lot of attention in part due to the potential applications of such systems.  In addition to the being a clean energy alternative, it provides a pathway for implantable microelectronic devices, such as pacemakers, to be powered by interstitial fluid and eliminate the need for batteries.  Furthermore, using interstitial fluid as fuel sources will drastically reduce necessary invasive surgeries to replace batteries.  Additionally, cost to such patients will be reduced while quality of life enhanced.  The research presents a unique platform for harvesting energy from glucose.  Using semiconductor cleanroom techniques, electrically conductive palladium nanowires are grown on anodized aluminum oxide templates using silicon and glass as supporting substrates.  Photolithography is used to create two non-continuous gold windows and contact pads on the substrates.   AAO templates are attached to the two gold windows and palladium nanowires are electrochemically grown on the AAO templates.  Glucose oxidase and catalase are immobilized on the anode and laccase on the cathode.  In the presence of glucose, electrons are released that result in the generation of voltage and current.  The current-voltage behavior of the fuel cell, as well as electrochemical properties, is characterized using standard performance metrics.  In 5 mM glucose solution with a neutral pH of 7.3, the open circuit voltage obtained was 335 mV and the short circuit current of 6 ?A to yield a maximum power output of 1.38 ?W.

The Association of Neighborhood Crime and Cardiovascular Risk Factors in the Healthy Aging in Neighborhoods of Diversity Across the Life Span (HANDLS) Study

description: Aspects of neighborhood socioeconomic status (SES) may be associated with cardiovascular disease (CVD) independent of individual SES and other known risk factors. The present study investigated relations of neighborhood crime to CVD risk factors, and potential psychosocial mediators, in a sample of 1787 community-dwelling Black and White men and women who participated in the Healthy Aging in Neighborhoods of Diversity Across the Lifespan Study (HANDLS). Objective neighborhood crime rates and a composite measure of psychosocial vulnerability were examined for associations with waist circumference, body mass index, systolic and diastolic blood pressure, total, HDL, and LDL cholesterol, triglycerides and glucose. No significant associations were noted for neighborhood crime and CVD risk in the entire sample. Exploratory analyses showed, among Whites, a significant association of greater overall crime rate with higher total and LDL cholesterol (p's < .05) among those not living in poverty. In Blacks, greater overall crime was associated significantly with higher diastolic blood pressure and glucose (p's < .05); and was associated significantly with lower HDL cholesterol in women (p < .05). These associations were not mediated by psychosocial vulnerability.  Thus, for Whites, those living above the poverty line may be most vulnerable to the impact of neighborhood crime on metabolic risk factors, whereas Blacks may be vulnerable for diastolic blood pressure and glucose, and HDL cholesterol in women only. Relations of crime to cardiovascular risk factors are subject to complex effect modification that is not explained by psychosocial mediators.

description: This paper presents a document analysis of the Norwegian qualification framework Professional Digital Competence Framework for Teachers (PDC) to explore the underlying assumptions within the policy. Employing a post-structural policy analysis, the paper analyses the representation of the ‘problem’ of PDC by asking what the document does in relation to teachers’ professionalism. To do this, the analysis explores the underlying assumptions of the policy document and its construction of the problem. The paper argues that the policy document is constructing a particular image of a digital future and presenting the teacher as the ‘problem’ in realising this imagined future. The paper discusses the discursive effects of this policy and explores the implications for the teaching profession.
Mass and Redshift Dependence of Star Formation in Relaxed Galaxy Clusters

description: We investigate the star-formation properties of dynamically relaxed galaxy clusters as a function of cluster mass for 308 low-redshift clusters drawn from the Sloan Digital Sky Survey (SDSS) C4 cluster catalog. It is important to establish if cluster star-formation properties have a mass dependence before comparing clusters at different epochs, and here we use cluster velocity dispersion as a measure of cluster mass. We find that the total stellar mass, the number of star-forming galaxies, and total star-formation rate scale linearly with the number of member galaxies, with no residual dependence on cluster velocity dispersion. With the mass-dependence of cluster star-formation rates established, we compare the SDSS clusters with a sample of z = 0.75 clusters from the literature and find that on average the total H-alpha luminosity of the high-redshift clusters is 10 times greater than that of the low-redshift clusters. This can be explained by a decline in the H-alpha luminosities of individual cluster galaxies by a factor of up to 10 since z = 0.75. The magnitude of this evolution is comparable to that of field galaxies over a similar redshift interval, and thus the effect of the cluster environment on the evolution of star-forming galaxies is at most modest. Our results suggest that the physical mechanism driving the evolution of cluster star-formation rates is independent of cluster mass, at least for clusters with velocity dispersion greater than 450 km/s, and operates over a fairly long timescale such that the star-formation rates of individual galaxies decline by an order of magnitude over ~7 billion years.

Near-infrared polarimetry setting constraints on the orbiting spot model for Sgr A* flares

description: Context: Recent near-infrared polarization measurements of SgrA* show that its emission is significantly polarized during flares and consists of a non- or weakly polarized main flare with highly polarized sub-flares. The flare activity suggests a quasi-periodicity of ~20 minutes in agreement with previous observations. Aims: By simultaneous fitting of the lightcurve fluctuations and the time-variable polarization angle, we address the question of whether these changes are consistent with a simple hot spot/ring model, in which the interplay of relativistic effects plays the major role, or whether some more complex dependency of the intrinsic emissivity is required. Methods: We discuss the significance of the 20min peak in the periodogram of a flare from 2003. We consider all general relativistic effects that imprint on the polarization degree and angle and fit the recent polarimetric data, assuming that the synchrotron mechanism is responsible for the intrinsic polarization and considering two different magnetic field configurations. Results: Within the quality of the available data, we think that the model of a single spot in addition to an underlying ring is favoured. In this model the broad near-infrared flares of Sgr A* are due to a sound wave that travels around the MBH once while the sub-flares, superimposed on the broad flare, are due to transiently heated and accelerated electrons which can be modeled as a plasma blob. Within this model it turns out that a strong statement about the spin parameter is difficult to achieve, while the inclination can be constrained to values > 35 deg on a 3sigma level.

description: New facilities of the 2020s, such as the High Luminosity Large Hadron Collider (HL-LHC), will be relevant through at least the 2030s. This means that their software efforts and those that are used to analyze their data need to consider sustainability to enable their adaptability to new challenges, longevity, and efficiency, over at least this period. This will help ensure that this software will be easier to develop and maintain, that it remains available in the future on new platforms, that it meets new needs, and that it is as reusable as possible. This report discusses a virtual half-day workshop on "Software Sustainability and High Energy Physics" that aimed 1) to bring together experts from HEP as well as those from outside to share their experiences and practices, and 2) to articulate a vision that helps the Institute for Research and Innovation in Software for High Energy Physics (IRIS-HEP) to create a work plan to implement elements of software sustainability. Software sustainability practices could lead to new collaborations, including elements of HEP software being directly used outside the field, and, as has happened more frequently in recent years, to HEP developers contributing to software developed outside the field rather than reinventing it. A focus on and skills related to sustainable software will give HEP software developers an important skill that is essential to careers in the realm of software, inside or outside HEP. The report closes with recommendations to improve software sustainability in HEP, aimed at the HEP community via IRIS-HEP and the HEP Software Foundation (HSF).

description: It will be shown analytically that the light sector of the identity block of a mixed heavy-light correlator in the large central charge limit is given by a correlation function of light operators on an effective background geometry. This geometry is generated by the presence of the heavy operators. It is shown that this background geometry is a solution to the Liouville equation of motion sourced by corresponding heavy vertex operators and subsequently that the light sector of the identity block matches the Liouville correlation function in the semi-classical limit. This method effectively captures the spirit of Einstein gravity as a theory of dynamical geometry in AdS/CFT. The reason being that Liouville theory is closely related to semi-classical asymptotically AdS$_3$ gravity.

description: Nonlinear electrodynamic (NLED) theories are well-motivated for their extensions to classical electrodynamics in the strong field regime, and have been extensively investigated in seeking for regular black hole solutions. In this paper, we focus on two spherically symmetric and static black hole solutions based on two types of NLED models: the Euler-Heisenberg NLED model and the Bronnikov NLED model, and calculate the weak deflection angle of light by these two black holes with the help of the Gauss-Bonnet theorem. We investigate the effects of the one-loop corrections to quantum electrodynamics on the deflection angle and analyse the behavior of the deflection angle by a regular magnetically charged black hole. It is found that the weak deflection angle of the electrically charged Einstein-Euler-Heisenberg black hole increases with the one-loop corrections and the regular magnetically charged black hole based on the Bronnikov NLED model has a smaller deflection angle than the singular one. Besides, we also calculate the deflection angle of light by the geodesic method for verification. In addition, we discuss the effects of a cold non-magnetized plasma on the deflection angle and find that the deflection angle increases with the plasma parameter.

description: We report the discovery of a new ultra-faint stellar system found near the Magellanic Clouds in the DECam Local Volume Exploration (DELVE) Survey. This new system, DELVE J0155$-$6815 (DELVE 2), is located at a heliocentric distance of $D_{\odot} = 71 \pm 4\text{ kpc}$, which places it at a 3D physical separation of 12 kpc from the center of Small Magellanic Cloud (SMC) and 28 kpc from the center of the Large Magellanic Cloud (LMC). DELVE 2 is identified as a resolved overdensity of old ($τ> 13.3\text{ Gyr}$) and metal-poor (${\rm [Fe/H]} = -2.0_{-0.5}^{+0.2}$ dex) stars with a projected half-light radius of $r_{1/2} = 21^{+4}_{-3}\text{ pc}$ and an absolute magnitude of $M_V = -2.1^{+0.4}_{-0.5}\text{ mag}$. The size and luminosity of DELVE 2 are consistent with both the population of recently discovered ultra-faint globular clusters and the smallest ultra-faint dwarf galaxies. However, its age and metallicity would place it among the oldest and most metal-poor globular clusters in the Magellanic system. DELVE 2 is detected in Gaia DR2 with a clear proper motion signal, with multiple blue horizontal branch stars near the centroid of the system with proper motions consistent with the systemic mean. We measure the system proper motion to be $(μ_α \cos δ, μ_δ)= (1.02_{-0.25}^{+0.24}, -0.85_{-0.19}^{+0.18})$ mas yr$^{-1}$. We compare the spatial position and proper motion of DELVE 2 with simulations of the accreted satellite population of the LMC and find that it is very likely to be associated with the LMC.

description: We investigate cosmological evolution and implications of cosmic strings with time-dependent tension. We derive basic equations of time development of the correlation length and the velocity of such strings, based on the one scale model. Then, we find that, in the case where the tension depends on some power of the cosmic time, cosmic strings with time-dependent tension goes into the scaling solution if the power is lower than a critical value. We also discuss cosmic microwave background anisotropy and matter power spectra produced by these strings. The constraints on their tensions from the Wilkinson microwave anisotropy probe (WMAP) three year data and Sloan digital sky survey (SDSS) data are also given.

description: The turbulent boundary layer over a Gaussian shaped bump is computed by direct numerical simulation (DNS) of the incompressible Navier-Stokes equations. The two-dimensional bump causes a series of strong pressure gradients alternating in rapid succession. At the inflow, the momentum thickness Reynolds number is approximately 1,000 and the boundary layer thickness is 1/8 of the bump height. DNS results show that the strong favorable pressure gradient (FPG) causes the boundary layer to enter a relaminarization process. The near-wall turbulence is significantly weakened and becomes intermittent, however relaminarization does not complete. The streamwise velocity profiles deviate above the standard logarithmic law and the Reynolds shear stress is reduced. The strong acceleration also suppresses the wall-shear normalized turbulent kinetic energy production rate. At the bump peak, where the FPG switches to an adverse gradient (APG), the near-wall turbulence is suddenly enhanced through a partial retransition process. This results in a new highly energized internal layer which is more resilient to the strong APG and only produces incipient flow separation on the downstream side. In the strong FPG and APG regions, the inner and outer layers become largely independent of each other. The near-wall region responds to the pressure gradients and determines the skin friction. The outer layer behaves similarly to a free-shear layer subject to pressure gradients and mean streamline curvature effects. Results from a RANS simulation of the bump are also discussed and clearly show the lack of predictive capacity of the near-wall pressure gradient effects on the mean flow.

description: Whenever a microservice is the protagonist there is always an antagonist called monolithic application. Both terms are not well defined and is dangerous to use ambiguous terms which could lead to misconceptions. In the context of microservices, deficiencies in the use of abstract concepts and the interpretation of dependencies can also be observed. As a result, microservices are ascribed properties that are not true in general. This article discusses some misconceptions that can be found in the literature.

description: Aim: To examine the association between the integrated care competencies and cross-cultural competence of registered nurses prior to the integration of social and healthcare services in Finland. Design: A descriptive correlational cross-sectional questionnaire survey was conducted. Methods: A simple random sample of 10,000 registered nurses was drawn from the Finnish Central Register of Valvira (National Supervisory Authority for Welfare and Health); 7000 of them were sent the online questionnaire, and a total of 1232 registered nurses participated in the study. We collected data using background questions, revised versions of the Competent Workforce for the Future tool in the four domains of client orientation, responsibility for personal or relative's welfare, fluency and clarity of services and access to the services and of the Cross-Cultural Competence of Healthcare Professional tool in the four domains of motivation/curiosity, attitude, skill and emotion/empathy. Results: Participants demonstrated a high level of integrated care competencies (mean = 4.00,SD ± 0.49).Anassociation was observed between integrated care competencies and their domains of skills, motivation/curiosity, emotions/empathy, and cross-cultural competence (p< 0.001). Female sex, older age, more working experience, employment in the private sector, and higher self-rated competence for working in a multicultural environment were positively associated with higher integrated care competencies. Conclusion: It is recommended that nurse managers and nurse educators emphasize the development of registered nurses' cross-cultural competence alongside integrated care competencies to meet the needs of different individuals and communities when providing integrated care. Patient or Public Contribution: Finnish registered nurses including all types of nurses, midwives and paramedics working the public and private healthcare, were involved in this study by responding to the online survey.
Fisher information as a probe of spacetime structure: Relativistic quantum metrology in (A)dS

description: Relativistic quantum metrology studies the maximal achievable precision for estimating a physical quantity when both quantum and relativistic effects are taken into account. We study the relativistic quantum metrology of temperature in (3+1)-dimensional de Sitter and anti-de Sitter space. Using Unruh-DeWitt detectors coupled to a massless scalar field as probes and treating them as open quantum systems, we compute the Fisher information for estimating temperature. We investigate the effect of acceleration in dS, and the effect of boundary condition in AdS. We find that the phenomenology of the Fisher information in the two spacetimes can be unified, and analyze its dependence on temperature, detector energy gap, curvature, interaction time, and detector initial state. We then identify estimation strategies that maximize the Fisher information and therefore the precision of estimation.

Dynamics and Disequilibrium Carbon Chemistry in Hot Jupiter Atmospheres, With Application to HD 209458b

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: Chemical equilibrium considerations suggest that, assuming solar elemental abundances, carbon on HD 209458b is sequestered primarily as carbon monoxide (CO) and methane (CH4). The relative mole fractions of CO(g) and CH4(g) in chemical equilibrium are expected to vary greatly according to variations in local temperature and pressure. We show, however, that in the p = 1--1000 mbar range, chemical equilibrium does not hold. To explore disequilibrium effects, we couple the chemical kinetics of CO and CH4 to a three-dimensional numerical model of HD 209458b's atmospheric circulation. These simulations show that vigorous dynamics caused by uneven heating of this tidally locked planet homogenize the CO and CH4 concentrations at p < 1 bar, even in the presence of lateral temperature variations of ~500--1000 K. In the 1--1000 mbar pressure range, we find that over 98% of the carbon is in CO. This is true even in cool regions where CH4 is much more stable thermodynamically. Our work shows furthermore that planets 300--500 K cooler than HD 209458b can also have abundant CO in their upper layers due to disequilibrium effects. We demonstrate several interesting observational consequences of these results.

description: The LiteBIRD satellite is planned to be launched by JAXA in the late 2020s. Its main purpose is to observe the large-scale B-mode polarization in the Cosmic Microwave Background (CMB) anticipated from the Inflation theory. LiteBIRD will observe the sky for three years at the second Lagrangian point (L2) of the Sun-Earth system. Planck was the predecessor for observing the CMB at L2, and the onboard High Frequency Instrument (HFI) suffered contamination by glitches caused by the cosmic-ray (CR) hits. We consider the CR hits can also be a serious source of the systematic uncertainty for LiteBIRD. Thus, we have started a comprehensive end-to-end simulation study to assess impact of the CR hits for the LiteBIRD detectors. Here, we describe procedures to make maps and power spectra from the simulated time-ordered data, and present initial results. Our initial estimate is that $C_l^{BB}$ by CR is $\sim 2 \times 10^{-6}~μ$K$_{\mathrm{CMB}}^{2}$ in a one-year observation with 12 detectors assuming that the noise is 1~aW/$\sqrt{\mathrm{Hz}}$ for the differential mode of two detectors constituting a polarization pair.

description: Class of spherically symmetric Stephani cosmological models is examined in the context of evolution type. It is assumed that the equation of state at the symmetry center of the models is barotropic. Classification of cosmological models is performed depending on different values and signs of two free parameters. It is shown that for (hyperbolic geometry) dust-like cosmological model exhibits accelerated expansion at later stages of evolution. The Hubble and deceleration parameters are defined in the model and it is shown that the deceleration parameter decreases with the distance becoming negative for sufficiently distant galaxies. Redshift-magnitude relation is calculated and discussed in the context of SnIa observational data. It is noticed that the most distant supernovae of type Ia fit quite well to the redshift-magnitude relation calculated in the considered model without introducing the cosmological constant. It is also shown that the age of the universe in the model is longer than in the Friedmann model corresponding to the same Hubble and energy density parameters.
