description: By setting the urban-rural public goods supply model, this paper evaluates the effects of coordinating supply public goods on resource allocation and welfare from efficiency and fairness, and examines the necessity and possibility of coordinating public goods supply in urban and rural areas. The model assumes that the population size of urban and rural areas is different, and the population can not flow freely between urban and rural areas; there are different degrees of spillover in the public goods supply. Model results show that coordinating public goods supply in urban and rural areas is the result of optimizing resource allocation efficiency, but the residents' individual utility level will not necessarily improve, so residents' willingness to support coordinated urban-rural supply is different, and public goods spillover and different tax systems are the factors that affect the residents' utility level. Finally, this paper uses the practice of coordinating urban and rural compulsory education in Chengdu City to confirm the above conclusions.

description: In order to examine the prediction that the broad-line radio galaxies (BLRGs) with double-peaked Balmer lines harbor an accretion disk characterized by an advection-dominated accretion flow (ADAF) in their nuclei, we investigate narrow emission-line flux ratios of the narrow-line regions which are photoionized by the nuclear continuum radiation. We compile data from the literature and confirm the pioneering work of Eracleous & Halpern that the BLRGs with the double-peaked Balmer emission exhibit larger flux ratios of both [O I]6300/[O III]5007 and [O II]3727/[O III]5007 than the BLRGs without the double-peaked Balmer emission. To examine whether or not these properties are attributed to the difference in the spectral energy distribution (SED) of the ionizing radiation between the BLRGs with and without the double-peaked Balmer emission, we perform photoionization model calculations using two types of input continuum radiation; one has the strong big blue bump which is expected for standard optically-thick accretion disks and another does not exhibit a strong big blue bump as expected for optically-thin ADAFs. We find that the data of the BLRGs with the double-peaked Balmer lines are consistent with the models adopting the SED without a strong big blue bump while the data of the BLRGs without the double-peaked emission lines are well described by the models adopting the SED with a strong big blue bump. On the other hand, the observed differences in the NLR emission is hard to be explain by the difference in the contribution of shocks. These results support the idea that the double-peaked Balmer lines arise at an outer region of an accretion disk which is illuminated by an inner, geometrically-thick ADAF.

Ще одним сутнісним моментом є особливості художнього розвитку дитини: до трьох років життя вона знаходиться на так званому до зображувальному етапі, коли про створення художніх образів ще не йдеться. Тільки на межі трирічного віку дитина може задумувати, що зображатиме, добирати художні матеріали і втілювати свій замисел.

description: Recent analyses of 21-cm neutral hydrogen (HI) emission have demonstrated that HI gas is organized into linear filamentary structures that are preferentially aligned with the local magnetic field, and that the coherence of these structures in velocity space traces line-of-sight magnetic field tangling. On this basis, we introduce a paradigm for modeling the properties of magnetized, dusty regions of the interstellar medium, using the orientation of HI structure at different velocities to map "magnetically coherent" regions of space. We construct three-dimensional (position-position-velocity) Stokes parameter maps using HI4PI full-sky spectroscopic HI data. We compare these maps, integrated over the velocity dimension, to Planck maps of the polarized dust emission at 353 GHz. Without any free parameters governing the relation between HI intensity and dust emission, we find that our $Q$ and $U$ maps are highly correlated ($r > 0.75$) with the 353 GHz $Q$ and $U$ maps of polarized dust emission observed by Planck and reproduce many of its large-scale features. The $E/B$ ratio of the dust emission maps agrees well with the HI-derived maps at large angular scales ($\ell \lesssim 120$), supporting the interpretation that this asymmetry arises from the coupling of linear density structures to the Galactic magnetic field. We demonstrate that our 3D Stokes parameter maps constrain the 3D structure of the Galactic interstellar medium and the orientation of the interstellar magnetic field.

description: Health and nutrition status including dietary adequacy are basic components of the human development and indicators for welfare in a certain community. The study focused upon how far the socio-economic environment would affect the dietary pattern and adequacy in Egypt. The current dietary pattern was compared with that before the economic reform adjustment, i.e. before 1986. Dietary adequacy of energy and protein was assessed to define the poverty line among urban and rural populations. The investigated changes in the socio-economic environment were income level, distribution, growth and price level by region; as well as demographic features of the household. Finally, the study discussed policy implications on both micro and macro level and provided recommendations to the decision-makers for how to secure adequate diet quantity-wise as well as quality-wise for poor categories and vulnerable groups among the Egyptian community.

description: The study generates a case study model for social project appraisal that simulates the economic treatment of a depletable resource, environment protection from pollution effects and public goods damage. The project is a high dam project that generates a an "environmental friendly technology" for energy creation "Hydroelectric" that saves a depl eted fuel and reduces the premature death probability and it preserves water for i rrigating additional newly reclaimed land for agricultural production. Although, this model simulates the comparable one in Egypt, its volume and figures were simplified here for several reasons. The study is interest in building up a model to test its validity for further applications, rather than to restrict it to access the feasibility or validity of the High Dam, as the protection of Egypt from drought several times within the last three decades was enough evidence to judge how valid was the decision to establish it. The externalities of the actual "Aswan" high dam are much more beyond what presented here.

description: Quantum error correction is vital for implementing universal quantum computing. A key component is the encoding circuit that maps a product state of physical qubits into the encoded multipartite entangled logical state. Known methods are typically not 'optimal' either in terms of the circuit depth (and therefore the error burden) or the specifics of the target platform, i.e. the native gates and topology of a system. This work introduces a variational compiler for efficiently finding the encoding circuit of general quantum error correcting codes with given quantum hardware. Focusing on the noisy intermediate scale quantum regime, we show how to systematically compile the circuit following an optimising process seeking to minimise the number of noisy operations that are allowed by the noisy quantum hardware or to obtain the highest fidelity of the encoded state with noisy gates. We demonstrate our method by deriving novel encoders for logic states of the five qubit code and the seven qubit Steane code. We describe ways to augment the discovered circuits with error detection. Our method is applicable quite generally for compiling the encoding circuits of quantum error correcting codes.

We find agreement between the matrix model and the gauge theory descriptions of these theories. The analysis leads to a partial description of the Higgs branch of the gauge theory. We argue that the transition between phases with different unbroken flavor symmetry groups is related to the appearance of cuts in the matrix model computation.

description: The ground state properties and low-lying excitations of a (quasi) one-dimensional system of longitudinally confined interacting bosons are studied. This is achieved by extending Haldane's harmonic-fluid description to open boundary conditions. The boson density, one-particle density matrix, and momentum distribution are obtained accounting for finite-size and boundary effects. Friedel oscillations are found in the density. Finite-size scaling of the momentum distribution at zero momentum is proposed as a method to obtain from the experiment the exponent that governs phase correlations. The strong correlations between bosons induced by reduced dimensionality and interactions are displayed by a Bijl-Jastrow wave function for the ground state, which is also derived.

description: The aim of this investigation was an assessment of the application effectiveness of three alternatives for rainwater harvesting systems for individual households, in central Great Poland climatic conditions. During the study the amount of storm water, which can be collected from the 3 different size roof areas (80, 135, 185 m2) was assessed, in relation to the needs of a four-person family, for the region of the Tarnowo Podgórne. The receivable amount of rainwater was analysed at a rate of 10, 25, 50% of total annual precipitation occurrence probability, including the lower values, appeared in the period of 1960-2008. For the financial efficiency evaluation of investment, an indicator of the average annual cost per unit (Ws) and the net present value (NPV) were used. The results show that for the Great Poland region with the average annual sum of precipitation of 550mm, only the roof surfaces of 185 m2 and bigger allow obtaining the profits from collected rainwater and reimbursement for building rainwater harvesting installations within 30 years of its operation.

description: The structure and kinematics of gaseous, disk-halo interfaces are imprinted with the processes that transfer mass, metals, and energy between galactic disks and their environments. We study the extraplanar diffuse ionized gas (eDIG) layer in the interacting, star-forming galaxy NGC 5775 to better understand the consequences of star-formation feedback on the dynamical state of the thick-disk interstellar medium (ISM). Combining emission-line spectroscopy from the Robert Stobie Spectrograph on the Southern African Large Telescope with radio continuum observations from Continuum Halos in Nearby Galaxies - an EVLA Survey, we ask whether thermal, turbulent, magnetic field, and cosmic-ray pressure gradients can stably support the eDIG layer in dynamical equilibrium. This model fails to reproduce the observed exponential electron scale heights of the eDIG thick disk and halo on the northeast ($h_{z,e} = 0.6, 7.5$ kpc) and southwest ($h_{z,e} = 0.8, 3.6$ kpc) sides of the galaxy at $R < 11$ kpc. We report the first definitive detection of an increasing eDIG velocity dispersion as a function of height above the disk. Blueshifted gas along the minor axis at large distances from the midplane hints at a disk-halo circulation and/or ram pressure effects caused by the ongoing interaction with NGC 5774. This work motivates further integral field unit and/or Fabry-Perot spectroscopy of galaxies with a range of star-formation rates to develop a spatially-resolved understanding of the role of star-formation feedback in shaping the kinematics of the disk-halo interface.

description: In this paper we study the dynamics of smallholder participation in export value chains focusing on the example of small-scale broccoli producers in the highlands of Ecuador. We analyze the extent of participation over an 11-year time period using correlated random effects and diff-GMM models and explain the hazards of dropping out of the export chain based on a multi-spell cox duration model. The empirical results suggest that small-scale farmers' exit from the export sector is accelerated by hold-ups experienced in the past and that family ties play an important role in farmers' marketing decisions. Negative external shocks – such as the global financial crisis starting in 2007 that was associated with the bankruptcy of the main buyer in our case study – represent a major threat towards the sustainability of smallholder inclusion in high-value chains

description: A general model independent approach using the `off-shell Bethe Ansatz' is presented to obtain an integral representation of generalized form factors. The general techniques are applied to the quantum sine-Gordon model alias the massive Thirring model. Exact expressions of all matrix elements are obtained for several local operators. In particular soliton form factors of charge-less operators as for example all higher currents are investigated. It turns out that the various local operators correspond to specific scalar functions called p-functions. The identification of the local operators is performed. In particular the exact results are checked with Feynman graph expansion and full agreement is found. Furthermore all eigenvalues of the infinitely many conserved charges are calculated and the results agree with what is expected from the classical case. Within the frame work of integrable quantum field theories a general model independent `crossing' formula is derived. Furthermore the `bound state intertwiners' are introduced and the bound state form factors are investigated. The general results are again applied to the sine-Gordon model. The integrations are performed and in particular for the lowest breathers a simple formula for generalized form factors is obtained.

description: We propose a framework by which websites can coordinate to detect credential stuffing on individual user accounts. Our detection algorithm teases apart normal login behavior (involving password reuse, entering correct passwords into the wrong sites, etc.) from credential stuffing, by leveraging modern anomaly detection and carefully tracking suspicious logins. Websites coordinate using a novel private membership-test protocol, thereby ensuring that information about passwords is not leaked; this protocol is highly scalable, partly due to its use of cuckoo filters, and is more secure than similarly scalable alternatives in an important measure that we define. We use probabilistic model checking to estimate our credential-stuffing detection accuracy across a range of operating points. These methods might be of independent interest for their novel application of formal methods to estimate the usability impacts of our design. We show that even a minimal-infrastructure deployment of our framework should already support the combined login load experienced by the airline, hotel, retail, and consumer banking industries in the U.S.

Participation is not enough: practices associated with giving due weight to the views of children and young people in out-of-home care policy-making in Australia

description: The obligation to ensure children’s right to express themselves freely and to give due weight to their views in policy decision making is described in Article 12 of the United Nations Convention on the Rights of the Child (UNCRC). Despite findings that direct engagement and dialogue are critical for meaningful participation, little is known about what happens when policy actors listen and consider their views in out-of-home care (OOHC) policy-making in Australia. The dearth of evidence risks overlooking the lived experience expertise of children and young people whose lives are affected by child protection, OOHC, and other policy systems. This study used a critical-participatory methodology informed by practice theory, children’s rights and relational accountability. It aimed to identify practices associated with giving due weight in policy-making, arrangements enabling and constraining practice, and young people’s ideas about improving practice.
description: The study sought to extend participatory research practice by involving co-researchers in each research phase, including design of research methods, data collection, data analysis, knowledge co-creation and dissemination. Five young co-researchers with first hand experience in OOHC were engaged in observing over 100 policy actors in six national and state policy-making sites and interviewing 12 senior policy practitioners in Phase 1. In Phase 2, an eBook practice resource was co-created with co-researchers and shared with over 700 readers. Findings uncovered 14 policy-making practices, including four directly associated with giving due weight: listening and giving serious consideration, feedback and reporting back, amplifying their views and including children and young people as policy actors. Participatory analysis uncovered complex cultural-discursive, material-economic, and socio-political arrangements that enabled contracting out consultation and engaging caseworkers as experts on children and young people’s lives. Arrangements also constrained direct engagement, listening and including children and young people as policy actors.
description: Improving the practice of giving due weight in participating Australian policy organisations relies on valuing the lived experience of children and young people and engaging in direct and ongoing dialogue with them. Such a dialogue is an opportunity to mobilise trust and relational accountability between policy actors. Beyond participation, giving due weight is an opportunity to activate ethical responsiveness in the organisations that serve children and young people’s welfare, wellbeing and safety for a more child-centred approach to policy practice.

description: In this article, we study the impact of an institutional intervention on market efficiency in Ethiopia. More specifically, we study whether regional warehouses that are connected to a national commodity exchange reduce transaction cost and price dispersion between regions. In order to identify the causal effect we take advantage of the fact that the warehouses that are connected to the Ethiopian Commodity Exchange were sequentially rolled out. Using retail price data and information about warehouse operation from 2007-2012, we find that the average price spread between market pairs is reduced by 0.86-1.775 ETB when both markets have an operating warehouse. This is a substantial reduction considering that the average price spread over the full period is 3.33 ETB.

description: In the conventional misalignment mechanism, the axion field has a constant initial field value in the early universe and later begins to oscillate. We present an alternative scenario where the axion field has a nonzero initial velocity, allowing an axion decay constant much below the conventional prediction from axion dark matter. This axion velocity can be generated from explicit breaking of the axion shift symmetry in the early universe, which may occur as this symmetry is approximate.

A linear electrostatic quadrupole with a curved section selects molecules with small transverse and longitudinal velocities. The source is tested with formaldehyde (H2CO) and deuterated ammonia (ND3). With H2CO a continuous flux is measured of approximately 10^9/s and a longitudinal temperature of a few K. The data are compared with the result of a Monte Carlo simulation.

description: The study provides the basic parameters and technical coefficients of the cost benefit analysis model for the socio-economic and environmental impact of introducing a renewable energy source (Hydroelectric) that replaced the conventional depleted fuel source. The study applied this model for quantitative profile of the socio-economic and environmental impact as net present value of replacement the conventional depleted fuel for a renewable energy source. It shows that the avoidance of premature mortality is the main source of benefits, even though it is an external benefit, which in most feasibility studies is ignored

description: We present the stellar mass-[Fe/H] and mass-[Mg/H] relation of quiescent galaxies in two galaxy clusters at $z\sim0.39$ and $z\sim0.54$. We derive the age, [Fe/H], and [Mg/Fe] for each individual galaxy using a full-spectrum fitting technique. By comparing with the relations for $z\sim0$ SDSS galaxies, we confirm our previous finding that the mass-[Fe/H] relation evolves with redshift. The mass-[Fe/H] relation at higher redshift has lower normalization and possibly steeper slope. However, based on our sample, the mass-[Mg/H] relation does not evolve over the observed redshift range. We use a simple analytic chemical evolution model to constrain average outflow that these galaxies experience over their lifetime, via the calculation of mass-loading factor. We find that the average mass-loading factor $η$ is a power-law function of galaxy stellar mass, $η\propto M_*^{-0.21\pm0.09}$. The measured mass-loading factors are consistent with the results of other observational methods for outflow measurements and with the predictions where outflow is caused by star formation feedback in turbulent disks.

Gemäß internationaler Menschenrechtsnormen haben Menschen ein Recht auf qualitativ hochwertige Informationen über Empfängnisverhütung, allerdings wird die Qualität der Online-Informationen zu diesem Thema in der aktuellen Fachdiskussionen als problematisch eingestuft. Da die „Pille“ das beliebteste Verhütungsmittel bei jungen Menschen darstellt und die Informationsqualität über Verhütung im Internet in Frage gestellt wird, werden in dieser Arbeit häufig angezeigte Internetseiten über die „Pille“ mittels einer qualitativen Inhaltsanalyse untersucht und deren Informationsgehalt und - qualität bewertet. Die Anwendung der „Pille“ stellt speziell Jugendliche vor einige Herausforderungen, wie zB. die regelmäßige Einnahme, verordnungsrechtliche Regelungen und lebensgefährliche Nebenwirkungen. Die ausgewählten Internetangebote wurden nach diesen für Jugendliche wichtigen Informationen durchsucht und ihre Qualität eingeschätzt, wobei das Ergebnis insgesamt kritisch ausfällt. Sozialarbeitende sollten junge Menschen daher ausführlich über die „Pille“ aufklären, Onlinesexualaufklärung in sexual- und medienpädagogischen Angeboten verstärkt ansprechen, sowie die Medienkompetenz der Jugendlichen fördern.

description: A universal symmetric truncation of the bosonic string Hilbert space yields all known closed fermionic string theories in ten dimensions, their D-branes and their open descendants. We highlight the crucial role played by group theory and two-dimensional conformal field theory in the construction and emphasize the predictive power of the truncation. Such circumstantial evidence points towards the existence of a mechanism which generates space-time fermions out of bosons dynamically within the framework of bosonic string theory.

Assessing the current state of affairs surrounding education on counseling direct-to-consumer testing patients through surveying genetic counseling program directors
Creators: name: Swartz, Erin
Publisher: name: No Publisher Supplied

description: Direct-to-consumer (DTC) genetic testing is highly popular but often met with skepticism. Consumers who purchase DTC genetic testing commonly have questions or concerns about their test. Even though they are often not sought out directly, genetic counselors (GCs) may be uniquely poised as the best health care professionals to interface with these consumers. Therefore, genetic counselors should be educated and prepared to counsel consumers of DTC genetic testing. However, most practicing genetic counselors do not feel confident discussing DTC genetic testing with patients. In an effort to evaluate how current genetic counseling students are being educated on DTC genetic testing and whether the next generation of genetic counselors may be better equipped to counsel these patients, we investigated current curricula for genetic counseling training programs by surveying genetic counseling program directors. We found that 95.65% of genetic counseling programs surveyed include some level of education on DTC genetic testing in their programs’ curriculum and about half of programs are assessing the effectiveness of their education. Students are being educated about DTC genetic testing through combinations of course lectures, optional guest lectures, journal clubs, grand rounds, clinical rotations, non-clinical industry rotations, professional meetings, and small group discussions. It appears that genetic counseling students are being exposed to multiple aspects of DTC genetic testing via a variety of methods and settings. However, the effectiveness of this education is unclear because most students are not being assessed on what they are taught. These results suggest that while education on DTC genetic testing is established at most genetic counseling programs, it is neither standardized nor proven effective for training future genetic counselors to advise DTC test consumers.

description: We consider vacuum polarization from massless scalar electrodynamics in de Sitter inflation. The theory exhibits a 3+1 dimensional analogue of the Schwinger mechanism in which a photon mass is dynamically generated. The mechanism is generic for light scalar fields that couple minimally to gravity. The non-vanishing of the photon mass during inflation may result in magnetic fields on cosmological scales.

Survey of Mortgage Lenders, 2001
Survey of Mortgage Lenders, 1992-
Creators: name: Department For Transport, Local Government
Publisher: name: UK Data Service
Year: 2002

description: The Survey of Mortgage Lenders (SML) was launched on 1st April 1992 to succeed the 5% Sample Survey of Building Society Mortgage Completions (BSM) (See GN:33191). The aims were to improve the survey in three principal ways:

a) to broaden the range of institutions surveyed to incorporate other mortgage lenders in addition to building societies and Abbey National. With the entry of the high street banks and then the centralised lenders into the mortgage market, information provided by the building societies no longer represented the whole market in the way it did when the BSM was set up in the 1960s.

b) to extend its coverage to include further advances, remortgages and top-up loans in addition to first mortgages.

c) to increase the level of detail on the questionnaire especially with respect to the characteristics of the mortgage loan.

An important consideration for users of the data is that the SML figures allow continuity with the BSM survey results to be maintained for a reasonable period.

description: In this paper, we study a time-inconsistent consumption-investment problem with random endowments in a possibly incomplete market under general discount functions. We provide a necessary condition and a verification theorem for an open-loop equilibrium consumption-investment pair in terms of a coupled forward-backward stochastic differential equation. Moreover, we prove the uniqueness of the open-loop equilibrium pair by showing that the original time-inconsistent problem is equivalent to an associated time-consistent one.

description: We study the perturbative unitarity of scattering amplitudes in general dimensional reductions of Yang-Mills theories and general relativity on closed internal manifolds. For the tree amplitudes of the dimensionally reduced theory to have the expected high-energy behavior of the higher-dimensional theory, the masses and cubic couplings of the Kaluza-Klein states must satisfy certain sum rules that ensure there are nontrivial cancellations between Feynman diagrams. These sum rules give constraints on the spectra and triple overlap integrals of eigenfunctions of Laplacian operators on the internal manifold and can be proven directly using Hodge and eigenfunction decompositions. One consequence of these constraints is that there is an upper bound on the ratio of consecutive eigenvalues of the scalar Laplacian on closed Ricci-flat manifolds with special holonomy. This gives a sharp bound on the allowed gaps between Kaluza-Klein excitations of the graviton that also applies to Calabi-Yau compactifications of string theory.

description: This study explores the perceptions of study habits and their impact on academic performance among African students at Memorial University. The study employed a case study design and qualitative methods, utilizing semi-structured interviews with fifteen participants who were international students from Africa. Data were analyzed to know perceptions of students’ study habits and academic performance. The research seeks to understand how these students perceive their own study habits and their correlation with their academic success. The findings reveal a complex relationship influenced by factors such as time management skills, school environment, and socialization. While some students attribute their success to disciplined study routines, others highlight challenges such as time management and balancing academic demands with other responsibilities. This case study provides insights into the unique experiences of African students at Memorial University and offers recommendations for academic support.

description: A Monte Carlo method based on a density-of-states sampling is proposed for study of arbitrary statistical mechanical ensembles in a continuum. A random walk in the two-dimensional space of particle number and energy is used to estimate the density of states of the system; this density of states is continuously updated as the random walk visits individual states. The validity and usefulness of the method are demonstrated by applying it to the simulation of a Lennard-Jones fluid. Results for its thermodynamic properties, including the vapor-liquid phase coexistence curve, are shown to be in good agreement with high-accuracy literature data.

description: Present-day galaxies are surrounded by cool and enriched halo gas extending to hundreds of kiloparsecs. This halo gas is thought to be the dominant reservoir of material available to fuel future star formation, but direct constraints on its mass and physical properties have been difficult to obtain. We report the detection of a fast radio burst (FRB 181112) with arcsecond precision, which passes through the halo of a foreground galaxy. Analysis of the burst shows the halo gas has low net magnetization and turbulence. Our results imply predominantly diffuse gas in massive galactic halos, even those hosting active supermassive black holes, contrary to some previous results.
