description: Background To date, cultural clinical research has primarily focused on differences between ethnic groups when investigating causal beliefs about mental disorders. While individual as well as contextual factors are considered important for gaining a better understanding of cultural influences, research on causal beliefs about post-traumatic stress disorder (PTSD) and cultural correlates in laypersons is scarce. Objective This study aimed at gaining a better understanding of the association between causal beliefs about PTSD and cultural aspects, as well as other contextual and individual correlates of causal beliefs. Method We conducted a cross-sectional, vignette-based online survey with 737 laypersons from Mexico, Ecuador, Germany, Greece, and Russia. Participants completed the revised Illness Perception Questionnaire (IPQ-R) and reported several cultural and sociodemographic (e.g. country of residence, gender, personal values) as well as mental health–related variables (e.g. PTSD symptoms, previous seeking of help). Latent class analysis (LCA) was performed to identify subgroups of individuals expressing similar causal beliefs for PTSD. Multinomial logistic regression was used to analyse covariates of class membership. Results LCA resulted in a three-class solution of casual beliefs: a traumatic event–focused class (41.1%); an intrapersonal causes class (40.1%); and a multiple causes class (18.0%). Multinomial logistic regression analysis revealed country of residence, gender, personal value of security, PTSD symptoms, and mental health literacy as significant covariates of class membership. Conclusions Integrating a more diverse concept of culture into cultural clinical research can be a valuable addition to group comparisons based on nationality or ethnicity. Cultural clinical research needs to move towards a more integrated approach that accounts for the complexity of culture. Including additional contextual and sociodemographic factors can help to reach a more accurate understanding of the cultural influences on the development of causal beliefs and mental health.

description: It appears the major private benefit from peer reviewed journals such as the Review of Agricultural Economics (RAE) is certification. To maintain public support for our journals, increased efforts are needed to demonstrate the social benefits from peer reviewed publications. Research cost considerations have led agricultural economists to emphasize applied disciplinary work using secondary data and to ignore the important work of careful data collection and reporting. Moreover, pressures to publish have led to more isolated research efforts ignoring other disciplines. Recommendations to improve the relevance of journal publications include more active efforts by journal editors to make applied journals such as RAE more accessible to the public.

description: While remaining cognizant of several aspects of current information literacy (IL) instruction methods, including threshold concepts, the author re-created experiences shared by students as she searched for, analyzed, and compiled resources pertaining to the Renaissance. Good IL instruction supports education of the whole person, develops new modes of thinking, and defines scholars' relationships to their disciplines, their institution, and their communities. In short, good information literacy instruction draws from the ideals of the Renaissance and often results in a change of perspective after discovering deeper meanings in materials, concepts, and processes.

description: Graph Neural Networks (GNNs) have proven to be useful for many different practical applications. However, many existing GNN models have implicitly assumed homophily among the nodes connected in the graph, and therefore have largely overlooked the important setting of heterophily, where most connected nodes are from different classes. In this work, we propose a novel framework called CPGNN that generalizes GNNs for graphs with either homophily or heterophily. The proposed framework incorporates an interpretable compatibility matrix for modeling the heterophily or homophily level in the graph, which can be learned in an end-to-end fashion, enabling it to go beyond the assumption of strong homophily. Theoretically, we show that replacing the compatibility matrix in our framework with the identity (which represents pure homophily) reduces to GCN. Our extensive experiments demonstrate the effectiveness of our approach in more realistic and challenging experimental settings with significantly less training data compared to previous works: CPGNN variants achieve state-of-the-art results in heterophily settings with or without contextual node features, while maintaining comparable performance in homophily settings.

description: Given a $2k$-dimensional symplectic space $(Z,F)$ in $N$ variables, $1 < 2k \leq N$, over a global field $K$, we prove the existence of a symplectic basis for $(Z,F)$ of bounded height. This can be viewed as a version of Siegel's lemma for a symplectic space. As corollaries of our main result, we prove the existence of a small-height decomposition of $(Z,F)$ into hyperbolic planes, as well as the existence of two generating flags of totally isotropic subspaces. These present analogues of known results for quadratic spaces. A distinctive feature of our argument is that it works simultaneously for essentially any field with a product formula, algebraically closed or not. In fact, we prove an even more general version of these statements, where canonical height is replaced with twisted height. All bounds on height are explicit.

Economic factors were found to dominate the decision about future conservation effort. Attitudes towards conservation were found to have no significant influence on the decision. This fact may relate to the recent changes in the regulatory environment brought about by the 1985 Food Security Act which changed conservation from a voluntary to regulated nature.

description: Temporal modulation of components of electromagnetic systems provides an exceptional opportunity to engineer the response of those systems in a desired fashion, both in the time and frequency domains. For engineering time-modulated systems, one needs to thoroughly study the basic concepts and understand the salient characteristics of temporal modulation. In this paper, we carefully study physical models of basic bulk circuit elements -- capacitors, inductors, and resistors -- as frequency dispersive and time-varying components and study their effects in the case of periodical time modulations. We develop a solid theory for understanding these elements, and apply it to two important applications: wireless power transfer and antennas. For the first application, we show that by periodically modulating the mutual inductance between the transmitter and receiver, the fundamental limits of classical wireless power transfer systems can be overcome. Regarding the second application, we consider a time-varying source for electrically small dipole antennas and show how time modulation can enhance the antenna performance. The developed theory of electromagnetic systems engineered by temporal modulation is applicable from radio frequencies to optical wavelengths.

description: This paper introduces and briefly discusses the economics of two important trade and environment policy issues--international harmonization of environmental standards and the use trade measures for environmental purposes. Both issues are likely to generate lively international debate among environmentalists, industry representatives, and trade negotiators over the next few years. As the international community seeks new multilateral rules in these areas, agricultural producers will want to know how they will be affected. Thus, this paper also examines the potential impacts of environmental policy on the competitiveness of commodities unique to the Southern region of the United States.

Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we describe a new method for studying the hydrodynamical problem of a planet embedded in a gaseous disk. We use a finite volume method with an approximate Riemann solver (the Roe solver), together with a special way to integrate the source terms. This new source term integration scheme sheds new light on the Coriolis instability, and we show that our method does not suffer from this instability. The first results on flow structure and gap formation are presented, as well as accretion and migration rates. For Mpl < 0.1 M_J and Mpl > 1.0 M_J (M_J = Jupiter's mass) the accretion rates do not depend sensitively on numerical parameters, and we find that within the disk's lifetime a planet can grow to 3-4 M_J. In between these two limits numerics play a major role, leading to differences of more than 50 % for different numerical parameters. Migration rates are not affected by numerics at all as long as the mass inside the Roche lobe is not considered. We can reproduce the Type I and Type II migration for low-mass and high-mass planets, respectively, and the fastest moving planet of 0.1 M_J has a migration time of only 2.0 10^4 yr.

description: The technique of weak value amplification, proposed by Aharonov et al. in 1988, has been applied for various fields of physics for the purpose of precision measurement, which is made possible by exploiting the freedom of `postselection' specifying actively the final state in the physical process. Here we report for the first time the feasibility of utilizing the technique of weak value amplification in high energy particle physics, especially in measuring the CP-violating parameters in B meson decays, where the effective lifetime of the decay mode is expected to be prolonged statistically due to the postselection. Our analysis shows that, when adopted in the Belle II experiment at the SuperKEKB collider, the effective lifetime may be prolonged up to 2.6 times, and that the measurement precision of the CP-violating parameters will also be improved by its effect.

Soil/geotextile filtration behavior under dynamic conditions of cyclic flow and vibration

Publisher: name: University of British Columbia
Year: 2009

description: An evaluation of soil internal stability and soil/geotextile filtration compatibility for different types of loading conditions is important for the proper use and extension of empirically based design procedures. Static conditions like those found in earth dams and vertical drains, are characterized by steady flow. Dynamic conditions can, however, be present in some situations, for example under revetments due to hydraulic disturbance and under railways due to physical mechanical disturbance. To better understand the filtration performance of nonwoven geotextiles under dynamic conditions, this experimental study was undertaken. An existing permeation (Gradient Ratio) device was modified to perform tests with vibration. In addition, a new automatic cyclic Gradient Ratio device with a computerized control system was designed and commissioned to perform tests with cyclic flow. Forty-one combinations of four nonwoven geotextiles with narrow, wide, or gap-graded model soils were examined in testing. The reconstituted model soils were composed of glass bead fractions in the range between coarse silt and fine sand. The test program was conducted under a hydraulic gradient of four, and involved multi-stage tests. In the vibration tests, an initial stage of unidirectional flow was imposed and followed by a dynamic stage that involved physical disturbance using controlled energy blows at a frequency of 3 FIz. In cyclic flow tests the initial unidirectional flow was followed by reversing the direction of flow at frequencies of 0.2 Hz and 0.02 Hz, under both confined (av=25 kPa) and unconfined (ov=0 kPa) conditions. The results of each test were interpreted from the measurements of flow rate, water head distribution along the sample length, visual observations both during and after testing, and the weight and gradation of the particles that passed through the geotextile. Reflecting on existing design criteria and previous research work, the analysis and conclusions address issues of internal stability and soil geotextile compatibility under both static and dynamic conditions.

description: Intensity mapping of 21-cm line by several radio telescope experiments will probe the large-scale structure of the Universe in the post-reionization epoch. It requires a theoretical framework of neutral hydrogen (HI) clustering, such as modelling of HI power spectrum for Baryon Acoustic Oscillations (BAO) analysis. We propose a new method for reconstructing the HI map from dark matter distribution using N-body simulations. Several studies attempt to compute the HI power spectrum with N-body simulations by pasting HI gas at the dark matter halo centre, assuming the relation between the halo and HI masses. On the other hand, the method proposed in this paper reproduces the HI power spectrum from simulated dark matter distribution truncated at specific scales from the halo centre. With this method, the slope of HI power spectrum is reproduced well at the BAO scales, $k<1 h/{\rm Mpc}$. Furthermore, we find the fluctuation of spin temperature, which is often ignored at the post-reionization epoch, alters the power spectrum of brightness temperature by at most 8% in the power spectrum. Finally, we discuss how our method works by comparing the density profiles of HI and dark matter around the dark matter halos.

description: Feedforward networks have powerful approximation capabilities without the "explosion of parameters" problem faced by Fourier and polynomial expansions. This paper first introduces feedforward networks and describes their approximation capabilities, then we address several practical issues faced by applications of feedforward networks. First, we demonstrate networks can provide a reasonable estimate of a Bermudagrass hay fertilizer response function with the relatively sparse data often available from experiments. Second, we demonstrate that the estimated network with a practical number of hidden units provides reasonable flexibility. Third, we show how one can constrain feedforward networks to satisfy a priori information without losing their flexible functional form characteristic.

description: We present the One-orbital Ensemble Self-Consistent Field (OE-SCF) method, an {alternative} orbital-free DFT solver that extends the applicability of DFT to system sizes beyond the nanoscale while retaining the accuracy required to be predictive. OE-SCF is an iterative solver where the (typically computationally expensive) Pauli potential is treated as an external potential and updated after each iteration. Because only up to a dozen iterations are needed to reach convergence, OE-SCF dramatically outperforms current orbital-free DFT solvers. Employing merely a single CPU, we carried out the largest ab initio simulation for silicon-based materials to date. OE-SCF is able to converge the energy of bulk-cut Si nanoparticles as a function of their diameter up to 16 nm, for the first time reproducing known empirical results. We model polarization and interface charge transfer when a Si slab is sandwiched between two metal slabs where lattice matching mandates a very large slab size. Additionally, OE-SCF opens the door to adopt even more accurate functionals in orbital-free DFT simulations while still tackling systems sizes beyond the nanoscale.

description: The impact of an ad valorem pesticide tax on cropping patterns and pesticide use was examined in the South Central Texas Crop Reporting District. Output supply equations were econometrically estimated and used in the simulation. A 25 percent tax on pesticide was estimated to have major impacts on cropping patterns and on pesticide use. Assuming other input and output prices were unaffected, the supply of one important crop would fall by more than half. Demand for some of the highly soluble and persistent pesticides, which present the greatest threat to groundwater quality, would also decrease substantially (some as much as 50 percent).

A $ν$e$^{-}$ scattering experiment (Xmass) and/or a charged-current experiment (the indium detector) can measure the flux of electron pp-neutrinos. One can find the total flux of pp-neutrinos from a luminosity constraint after the contribution of $^7$Be and CNO neutrinos to the total luminosity of the Sun are measured. The radiochemical experiment utilizing a lithium target has the high sensitivity to the CNO neutrinos, thus, it has a good promise for the precise measurement of a mixing angle and for the test of a current theory of the evolution of the stars.

description: This paper investigates how the control and devolution of productive assets are allocated among husband and wife. Theory predicts that bargaining power within marriage depends on the division of assets upon divorce (exit option) and on control over assets during marriage (noncooperative marriage). In empirical applications, bargaining power is typically proxied by variables such as dowry payments, assets brought to marriage, and ownership of assets within marriage. Using detailed household data from rural Ethiopia, we show that assets brought to marriage, ownership of assets, control within marriage, and disposition upon death or divorce are only partly related (strictly speaking, surveyed households do not “own” land since all agricultural land is legally owned by the state). In rural Ethiopia, control over productive resources is centralized into the hands of the household head, be it a man or a woman, irrespective of ownership at or after marriage. Disposition upon death or divorce only loosely depends on individual ownership during marriage but control over assets is associated with larger claims over these assets upon divorce, a finding consistent with the presence of incentive problems. Assets brought into marriage have little impact on disposition upon death, but matter in case of divorce.

description: We study the K-correction for the case of emission lines formed in the X-ray illuminated atmosphere of a Roche lobe filling star. We compute the K-correction as function of the mass ratio 'q' and the disc flaring angle 'alpha' using a compact binary code where the companion's Roche lobe is divided into 10^5 resolution elements. We also study the effect of the inclination angle in the results. We apply our model to the case of the neutron star low-mass X-ray binary X1822-371 (V691 CrA), where a K-emission velocity K_em=300 +-8 km/s has been measured by Casares et al. (2003). Our numerical results, combined with previous determination of system parameters, yields 1.61Msun < M_NS < 2.32Msun and 0.44Msun < M_2 < 0.56Msun for the two binary components(i. e. 0.24 < q < 0.27), which provide a compelling evidence for a massive neutron star in this system. We also discuss the implications of these masses into the evolutionary history of the binary.

The real Chern-Simons wave function

Year: 2020
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We examine the status of the Chern-Simons (or Kodama) state from the point of view of a formulation of gravity that uses only real connection and metric variables and a real action. We may package the {\it real} connection variables into the complex Self-Dual Ashtekar connection (and will do so to make contact with previous work), but that operation is essentially cosmetic and can be undone at any step or even bypassed altogether. The action will remain the (real) Einstein-Cartan action, forgoing the addition of the usual Holst (or Nieh-Yan) term with an imaginary coefficient. It is then found that the constraints are solved by a modification of the Chern-Simons state which is a pure phase (in the Lorentzian theory, we stress), the phase containing only the fully gauge-invariant imaginary part of the Chern-Simons functional. Thus, the state for the "real theory" is non-pathological with regards to the most egregious criticisms facing its "non-real" cousin, solving the complex theory. A straightforward modification of the real Chern-Simons state is also a solution in quasi-topological theories based on the Euler invariant, for which the cosmological constant, $Λ$, is dynamical. In that case it is enough to shift the usual factor of $Λ$ in the wave function to the inside of the spatial Chern-Simons integral. The trick only works for the quasi-Euler theory with a critical coupling previously identified in the literature. It does not apply to the quasi-Pontryagin theory.

At the peristome, the height and width are 40 mm and 32 mm, respectively. The body chamber is 36 mm long and in lateral view has slightly convex margins. The conch cross section is elliptical. At a distance of ca 10 mm from the peristome, a ca 10 mm wide and 1.5 mm deep constriction forms an amphora-like aperture. The peristome is directly transverse with a wide, inconspicuous hyponomic sinus on the prosiphuncular side. Traces of a septal foramen close to the conch margin are preserved.
Remarks
The specimen is assigned to Dowlingoceras based on shape of the mature body chamber. Its size and rounded elliptical cross section can be compared with D. torni, while the gibbous shape and terminal constriction can be compared with D. kallholnense. Based on this single incomplete specimen, erection of a new species is impossible.

description: This paper models the assimilation process of migrants and shows evidence of the complementarity between their destination experience and upon-arrival human capital. Bayesian learning and dynamics of matching are modeled and empirically assessed, using panel data of wages from the Bangkok labor market in Thailand. The analysis incorporates (1) the heterogeneity of technologies and products, characteristic of urban labor markets, (2) imperfect information on migrants' types and skill demanded in the markets, and (3) migrants' optimal learning over time. Returns to destination experience emerge endogenously. Estimation results, which control migrants' selectivity by first-differencing procedures, show that (1) schooling returns are lower for migrants than for natives, (2) the accumulation of destination experience raises wages for migrants, (3) the experience effect is greater for more-educated agents, i.e., education and experience are complementary, and (4) the complementarity increases as destination experience accumulates. The results imply that more-educated migrants have higher learning efficiency and can perform tasks of greater complexity, ultimately yielding higher wage growth in the destination market. Simulations show that, due to the complementarity, wages for different levels of upon-arrival human capital diverge in the migrants' assimilation process.

description: The very large (100-1000) mass-to-light ratio applicable to the ultra-faint dwarf galaxies (UFDs) implies a high concentration of dark matter, thus rendering them ideal theatres for indirect signatures of dark matter. In this paper, we consider 14 recently discovered UFDs and study the electromagnetic radiation emanating from them over a wide range, from gamma ray down to radio frequencies. We analyze the Fermi-LAT data on high energy gamma rays and radio fluxes at the GMRT and VLA to obtain upper limits on annihilation cross section $\langleσv\rangle$ in a model independent way. We further discuss the sensitivity of the Square Kilometer Array radio telescope in probing the synchrotron radiation from the aforementioned UFDs. We also investigate the dependences of the said upper limits on the uncertainties in the determination of various astrophysical parameters.

description: In this work, gravitational collapse of a spherical cloud, consists of both dark matter and dark energy in the form of modified Chaplygin gas is studied. It is found that dark energy alone in the form of modified Chaplygin gas forms black hole. Also when both components of the fluid are present then the collapse favors the formation of black hole in cases the dark energy dominates over dark matter. The conclusion is totally opposite to the usually known results.

description: Summary indicators for measuring and assessing infant and child feeding practices are needed for research, communication and advocacy, and program evaluation. This paper reports on progress in developing a summary measure of infant and child feeding practices that addresses the following two challenges: infant and child feeding is multidimensional, and appropriate practices vary by age of the child. Much previous research in the area of infant and child feeding has focused on single practices over a narrow age range and so has not addressed the determinants and impact of adequate or optimal infant and child feeding. Using data from the Ethiopia Demographic and Health Survey, an infant and child feeding index is constructed, summarizing a range of key practices, including breastfeeding, bottle use, feeding frequency, and diet diversity. Because it provides age-specific scoring and incorporates various practices, the index is a useful analytic tool. The index is associated with an indicator of child growth (height-for-age) in bivariate and multivariate analyses. Examination of individual indicators shows that this association is driven by a strong positive association between one component "diet diversity" and height-for-age. Further work is required to establish the nature of the relationship between infant and child feeding indicators, nutrient adequacy, growth, and other outcomes. But because it can be used to illustrate the association between a set of recommended practices and growth, the index may serve as a communication tool with policymakers. Simulations show that the index accurately reflects an averaging of changes in individual component practices, and so it may also be of use to program managers who seek a summary measure for assessing program impact on a range of early feeding practices.
ATTRITION IN THE KWAZULU NATAL INCOME DYNAMICS STUDY, 1993-1998

description: Panel (or longitudinal) data often provide an understanding of the dynamic behavior of individual households not possible with cross-sectional or time-series information alone. However, a disturbing feature of this type of survey in both developed and developing countries is that there is often substantial, nonrandom attrition. Therefore, an important concern is the extent to which attrition inhibits inferences made using the data. This note examines attrition in the KwaZulu-Natal Income Dynamics Study (1993– 1998) and assesses the extent of attrition bias for a specific empirical example. The analysis shows that 1993 first round nonresponse is largely unrelated to observable characteristics of the communities other than indicators of migration activity. Multivariate regressions are then used to describe the characteristics of the households attriting in 1998, revealing the importance of distinguishing between two types of attriting households, those that moved and those that apparently moved but left no trace. For example, increased household size reduced the probability of either type of attrition, whereas measures of higher quality of fieldwork in the 1993 survey only reduced the probability that a household left no trace. While observable differences between attritors and non-attritors indicate attrition is nonrandom, it does not necessarily follow that estimated relationships based on the non-attriting sample suffer from attrition bias. To more directly explore attrition bias, which is by its nature model specific, this analysis estimates household-level expenditure functions correcting for attrition bias using standard Heckman selection procedures and a quality of 1993 interview variables as identifying instruments. There is positive selection, and although many of the other parameter estimates are quite similar, a Hausman test rejects the equality of coefficients between the corrected and uncorrected models. Therefore, this study concludes, at least for this simple case, that attrition does appear to bias the “behavioral” coefficients. These results are in contrast to other work using these data that suggests little attrition bias for different estimated models, highlighting that attrition is indeed model specific. Large levels of attrition do not always lead to attrition bias; however, sometimes they do. Since it is typically difficult to determine the bias for a particular analysis a priori, it behooves researchers using panel data not to avoid using panel data when there is attrition, but to always evaluate the effect of such bias on the analysis at hand.

description: There is hardly need these days to repeat that HIV/AIDS is devastating African societies and economies, threatening the hard-won human development gains of the past several decades. The changes to the development landscape wrought by AIDS demand a review of existing development actions at many levels, from households seeking to secure viable livelihoods, to policymakers attempting to better understand and internalize the implications of AIDS for their own sectoral goals and strategies. In this paper, we describe processes of understanding and responding that are needed for HIV/AIDS to be effectively addressed. Key concepts of resistance and resilience are illustrated through a discussion of the two-way interactions between food insecurity and HIV/AIDS, and their implications for the ways in which affected households, communities, and sectors may best respond. One major set of responses is required from the agriculture sector, as the need to secure and provision food for populations affected by HIV/AIDS is rapidly increasing as the impact waves hit. Food is the first priority of many people affected by the pandemic. We are also beginning to learn more about the crucial role of nutritional status—both in terms of susceptibility to HIV infection and transmission and in terms of the quality and quantity of like of HIV-positive individual. A sea change is required—in attitudes and consciousness of what HIV/AIDS is doing at different levels and the pathways through which it moves through societies. Such a new awareness may be facilitated by the use of an ‘HIV/AIDS lens’—essentially a tool for reviewing situations and development actions from the perspective of our evolving knowledge of AIDS interactions. The lens will facilitate the development of more HIV-relevant policies and programs of more sectors—and ultimately in larger scale, use of the lens, external support will likely be most effective in the long run where it is directed to preserving and developing institutional capacities to strengthen resistance and resilience.
