subject: Clinical and health psychology

description: This study investigated perceptions of and reactions to depression among recovered-depressed (RD) and never-depressed (ND) adults from the community. Participants completed a revised version of the Self Appraisal Questionnaire (Coyne & Calarco, 1995), reworded to assess the perceptions of others' depressive experiences. They also listened to audiotapes of confederates reading depressive and non-depressive scripts, and completed measures assessing their reactions to the tapes. Contrary to prediction, neither history of depression nor depression proneness predicted perceptions of or reactions to depression. However, higher depression proneness significantly correlated with stronger beliefs about depression contagion. Likewise, stronger contagion beliefs and lower levels of empathic responding significantly predicted behavioral rejection of the depressive stimulus. Results are discussed in context of interpersonal theory of depression.

description: The software of track reconstruction of the vertex chamber of BESII-VCJULI was studied when it was transplanted from the HP-Unix platform to PC-Linux. The problems of distinct dictionary storage and precision treatment in these two different platforms were found and settled in the modified software. Then the obvious differences of the candidate track number in an event and some track parameters caused by them were reduced from 74% to 0.02% and from 5% to 0.5%, respectively. As a result, the quality of the track finding was greatly improved and the CPU time saved.

Isotropic-Nematic Transition in Liquid-Crystalline Elastomers: Lattice Model with Quenched Disorder

description: When liquid-crystalline elastomers pass through the isotropic-nematic transition, the orientational order parameter and the elastic strain vary rapidly but smoothly, without the expected first-order discontinuity. This broadening of the phase transition is an important issue for applications of liquid-crystalline elastomers as actuators or artificial muscles. To understand this behavior, we develop a lattice model of liquid-crystalline elastomers, with local directors coupled to a global strain variable. In this model, we can consider either random-bond disorder (representing chemical heterogeneity) or random-field disorder (representing heterogeneous local stresses). Monte Carlo simulations show that both types of disorder cause the first-order isotropic-nematic transition to broaden into a smooth crossover, consistent with the experiments. For random-field disorder, the smooth crossover into an ordered state can be attributed to the long-range elastic interaction.

Targeting customers under response-dependent costs

description: This study provides a formal analysis of the customer targeting problem when the cost for a marketing action depends on the customer response and proposes a framework to estimate the decision variables for campaign profit optimization. Targeting a customer is profitable if the impact and associated profit of the marketing treatment are higher than its cost. Despite the growing literature on uplift models to identify the strongest treatment-responders, no research has investigated optimal targeting when the costs of the treatment are unknown at the time of the targeting decision. Stochastic costs are ubiquitous in direct marketing and customer retention campaigns because marketing incentives are conditioned on a positive customer response. This study makes two contributions to the literature, which are evaluated on an e-commerce coupon targeting campaign. First, we formally analyze the targeting decision problem under response-dependent costs. Profit-optimal targeting requires an estimate of the treatment effect on the customer and an estimate of the customer response probability under treatment. The empirical results demonstrate that the consideration of treatment cost substantially increases campaign profit when used for customer targeting in combination with an estimate of the average or customer-level treatment effect. Second, we propose a framework to jointly estimate the treatment effect and the response probability by combining methods for causal inference with a hurdle mixture model. The proposed causal hurdle model achieves competitive campaign profit while streamlining model building. Code is available at https://github.com/Humboldt-WI/response-dependent-costs.

description: Government by majority rule voting requires that compromise be attainable, but not too easily. Little of the nation’s business could be transacted without an ability on the part of the legislators and political parties to strike bargains, but government by majority rule voting could not withstand a bargaining equilibrium comparable to the general equilibrium in a competitive economy. Democratic government is designed to foster bargaining where it should be fostered and to impede bargaining where it should be impeded.

description: Many international macroeconomic models link the real exchange rate to a ratio of marginal utilities. We examine this link empirically, allowing the marginal utility of consumption to depend on government expenditure, real money balances, or external habit. We also consider two environments with incomplete asset markets; one with exogenously missing markets but an endogenous discount rate that anchors the distribution of wealth and one with endogenous market segmentation. Although none of these satisfies theoretical and over-identifying restrictions for every country, utility with external habit persistence provides the best match with real exchange rates for OECD countries between 1961 and 2001.
Black Hole as a Quantum Field Configuration

description: We describe 4D evaporating black holes as quantum field configurations by solving the semi-classical Einstein equation $G_{μν}=8πG \langle ψ|T_{μν}|ψ\rangle$ and quantum matter fields in a self-consistent manner. As the matter fields we consider $N$ massless free scalar fields ($N$ is large). We find a spherically symmetric self-consistent solution of the metric $g_{μν}$ and state $|ψ\rangle$. Here, $g_{μν}$ is locally $AdS_2\times S^2$ geometry, and $|ψ\rangle$ provides $\langle ψ|T_{μν}|ψ\rangle=\langle0|T_{μν}|0 \rangle+T_{μν}^{(ψ)}$, where $|0\rangle$ is the ground state of the matter fields in the metric and $T_{μν}^{(ψ)}$ consists of the excitation of s-waves that describe the collapsing matter and Hawking radiation with the ingoing negative energy flow. This object is supported by a large tangential pressure $\langle0|T^θ_θ|0 \rangle$ due to the vacuum fluctuation of the bound modes with large angular momenta. This describes the interior of the black hole when the back reaction of the evaporation is considered. The black hole is a compact object with a surface (instead of horizon) that looks like a conventional black hole from the outside and eventually evaporates without a singularity. If we count the number of self-consistent configurations $\{|ψ\rangle\}$, we reproduce the area law of the entropy. This tells that the information is carried by the s-waves inside the black hole. $|ψ\rangle$ also describes the process that the negative ingoing energy flow created with Hawking radiation is superposed on the collapsing matter to decrease the total energy while the total energy density remains positive. As a special case, we consider conformal matter fields and show that the interior metric is determined by the matter content of the theory, which leads to a new constraint to the matter content.

description: We prove global Schauder estimates for kinetic Kolmogorov equations with coefficients that are Hölder continuous in the spatial variables but only measurable in time. Compared to other available results in the literature, our estimates are optimal in the sense that the inherent Hölder spaces are the strongest possible under the given assumptions: in particular, under a parabolic Hörmander condition, we introduce Hölder norms defined in terms of the intrinsic geometry that the operator induces on the space-time variables. The technique is based on the existence and the regularity estimates of the fundamental solution of the equation. These results are essential for studying backward Kolmogorov equations associated with kinetic-type diffusions, e.g. stochastic Langevin equation.

description: New mathematics teachers may be considered for positions to teach upper-level mathematics courses. Whether or not they are prepared to do so will likely depend upon their pre-service experience. Veteran teachers without experience teaching upper-level mathematics may also be asked to teach this unfamiliar material. Teacher preparation and professional development in-service programs hold the potential for meeting the unique needs of mathematics teachers placed into these positions. This study sought to identify the needs of secondary mathematics teachers specifically in the area of upper-level mathematics preparation at the pre-service and in-service levels. A quantitative survey of 240 teachers and qualitative follow-up with sixteen teachers from three public school systems in Maryland focused on individual teacher preparation and experience. It was concluded that a significant number of mathematics teachers do not feel they were initially prepared to teach upper-level mathematics, and that veteran teachers without prior teaching experience in upper-level mathematics are unlikely to be prepared to teach these courses. In terms of content, mathematics teachers were divided regarding the amount of theoretical mathematics that is important in their training. Some firmly believe that mathematics teachers do not need to take more courses while others strongly disagree. Overall, teachers who maintain that they have a firm understanding of the secondary mathematics sequence believe that they are better prepared to teach upper-level mathematics. Specific components of mathematics education training valued by the majority of the surveyed teachers included pre-service mathematics and professional development workshops. The research also indicated that teachers who receive strong support and assistance from their colleagues are able to more successfully make the necessary transitions. Although teacher opinions regarding preparation are subjective, it is important to gather information from current teachers to learn what they perceive to be effective preparation techniques. It is also important to identify lapses in communication that exist within the mathematics education community. Teachers need to communicate their needs and expectations in order to help administrators and university faculty plan effective programs.

description: There is much research on consumption-savings problems with risky labor income and a constant interest rate and also on portfolio allocation with risky returns but nonstochastic labor income. Less is known quantitatively about the interaction between the two forms of risk. Under CRRA utility, undiversifiable income risk should be reflected in both savings rates and portfolio allocations. To quantify these effects in a model of consumption and portfolio choice, we adopt a semi-parametric projection method for solving dynamic programmes, based on generalized method of moments estimation of the parameters of approximate decision rules. We find that background income risk does affect optimal portfolios but that this effect may be difficult to detect empirically.

Three essays on the economic effects of crime on home ownership and suburban economic *growth
Creators: name: Burnham, Ray W.
Publisher: name: American University
Year: 2023

description: This dissertation consists of three essays. The first essay examines the impact of crime on residential housing decisions through its effect on mortgage default risk. The second essay is also a literature review that examines the relationship between crime and economic growth. The third essay uses a panel data set on 318 U.S. counties from 1982--1997 to examine whether inner-city crime affects suburban economic growth within the metropolitan area and migratory patterns to other metropolitan areas. The dependent variable is suburban county personal income growth. The independent variables include U.S. personal income growth, state personal income growth, county education and other expenditures, both violent and property crime rates within the central city and county total crime rates. A spatial variable, distance from the county to the central city, is also included. Ordinary least squares and random effects models are used to adjust for county and time specific effects. I find violent crime within the central city to have a negative impact on suburban county personal income growth and to have a lessening impact farther away from the central city. However, the impact of property crime is not as clear, perhaps due to simultaneity problems.

Dynamics of quantum anisotropies in a Taub Universe in the WKB approximation

description: We analyze the dynamics of a Taub cosmological model in the presence of a massless minimally coupled scalar field and a cosmological constant, in the limit when both the Universe volume and the scalar field live in a quasi-classical approximation. By other words, we study the dynamics of a quantum small anisotropy evolving on a de Sitter background and in the presence of a kinetic term of the inflaton field. We demonstrate that the quantum anisotropy exponentially decays during the Universe expansion, approaching a finite and small value. This result suggests that the quantum isotropization of the Universe during a de Sitter phase is much weaker than the corresponding classical evolution, favouring the survival of certain degree of anisotropy to the de Sitter phase. Finally we analyze the case when also the scalar field is considered as quantum variable, by showing how its variance naturally spreads because of no potential term significantly affects its dynamics. This behaviour results to be different from the anisotropy which is subjected to the potential coming out from the spatial curvature.

Ακολουθώντας την ποιοτική μεθοδολογική προσέγγιση διεξήχθησαν ημιδομημένες συνεντεύξεις με εννέα βιβλιοθηκονόμους από αντίστοιχες δημοτικές βιβλιοθήκες της διοικητικής Περιφερειακής Ενότητας Αθηνών. Τα ευρήματα από τη θεματική ανάλυση των δεδομένων κατέδειξαν ότι οι βιβλιοθηκονόμοι εκφράζουν την πεποίθησή τους και τηρούν τις αρχές της πνευματικής ελευθερίας, ακόμα και όταν αντιμετωπίζουν ηθικά διλήμματα και εσωτερικές συγκρούσεις που αφορούν την επαγγελματική δεοντολογία και τις προσωπικές τους πεποιθήσεις. Ωστόσο, κατά την επιλογή του αμφιλεγόμενου υλικού, οι προσωπικές αξίες των βιβλιοθηκoνόμων και η αντίληψη ότι οφείλουν να προστατεύουν την κοινότητα μερικές φορές τους οδηγούν σε λογοκρισία. Άλλοι παράγοντες που προκαλούν μια τέτοια συμπεριφορά είναι ο φόβος για πιθανές αντιδράσεις από την κοινότητα και η έλλειψη σαφούς και γραπτής πολιτικής για την ανάπτυξη των συλλογών των βιβλιοθηκών. Επιπροσθέτως, όταν οι βιβλιοθηκονόμοι αντιμετωπίζουν προκλήσεις κατά τη διαχείριση αμφιλεγόμενου υλικού, έχουν, σε μεμονωμένες περιπτώσεις, υιοθετήσει λογοκριτική συμπεριφορά που αναφέρεται κυρίως στην αποφυγή πρόσκτησης του αμφιλεγόμενου υλικού και την καθοδήγηση των αναγνωστών προς πιο «ασφαλείς» επιλογές και λιγότερο στην απόσυρση του υλικού.

[Lectotype: ANSP; ♂ California, USA; spring-summer 1873]
Diadasia bituberculata is almost exclusively found within the CFP. The BBPT collected 20 females and 15 males from various ecoregions of the CFP. Based on both previous records and our own findings, its flight season typically spans from March to June in sync with their host plant. This species is a specialist on Calystegia macrostegia (Schlising 1972); however, the BBPT has also collected females and males on Eriodictyon flowers in Sierra San Pedro Mártir and Sierra Blanca.

Key to their great versatility as quantum simulators is the ability to use engineered light potentials at the microscopic level. Here, we employ dynamically varying microscopic light potentials in a quantum-gas microscope to study commensurate and incommensurate 1D systems of interacting bosonic Rb atoms. Such incommensurate systems are analogous to doped insulating states that exhibit atom transport and compressibility. Initially, a commensurate system with unit filling and fixed atom number is prepared between two potential barriers. We deterministically create an incommensurate system by dynamically changing the position of the barriers such that the number of available lattice sites is reduced while retaining the atom number. Our systems are characterised by measuring the distribution of particles and holes as a function of the lattice filling, and interaction strength, and we probe the particle mobility by applying a bias potential. Our work provides the foundation for preparation of low-entropy states with controlled filling in optical-lattice experiments.

description: We provide two complementary approaches to the treatment of disorder in a fundamental nonequilibrium model, the asymmetric simple exclusion process. Firstly, a mean-field steady state mapping is generalized to the disordered case, where it provides a mapping of probability distributions and demonstrates how disorder results in a new flat regime in the steady state current--density plot for periodic boundary conditions. This effect was earlier observed by Tripathy and Barma but we provide treatment for more general distributions of disorder, including both numerical results and analytic expressions for the width $2Δ_C$ of the flat section. We then apply an argument based on moving shock fronts to show how this leads to an increase in the high current region of the phase diagram for open boundary conditions. Secondly, we show how equivalent results can be obtained easily by taking the continuum limit of the problem and then using a disordered version of the well-known Cole--Hopf mapping to linearize the equation. Within this approach we show that adding disorder induces a localization transformation (verified by numerical scaling), and $Δ_C$ maps to an inverse localization length, helping to give a new physical interpretation to the problem.

description: The martingale characterizes a kind of fairness or unbiased nature of the stochastic process which is associated with another stochastic process. If $x_t$ evolves according to the Langevin equation whose mean drift is $a_t$ as function of $x_t,$ and that $a_t$ as induced stochastic process is martingale in turn associated with the former process, then we show that the amplitude of $a_t$ is the Langevin function, which is originally the canonical response of a single classical Heisenberg spin under static field. Furthermore, the asymptotic limit of $x_t/t$ obeys the ensemble statistics of such Heisenberg spin.

Numerical criteria for divisors on $\M_{g}$ to be ample

description: The moduli space $\M_{g,n}$ of $n-$pointed stable curves of genus $g$ is stratified by the topological type of the curves being parametrized: the closure of the locus of curves with $k$ nodes has codimension $k$. The one dimensional components of this stratification are smooth rational curves (whose numerical equivalence classes are) called F-curves. The F-conjecture asserts that a divisor on $\M_{g,n}$ is ample if and only if it positively intersects the $F-$curves. In this paper the F-conjecture on $\M_{g,n}$ is reduced to showing that certain divisors in $\M_{0,N}$ for $N \leq g+n$ are equivalent to the sum of the canonical divisor plus an effective divisor supported on the boundary. As an application of the reduction, numerical criteria are given which if satisfied by a divisor $D$ on $\M_g$, show that $D$ is ample. Additionally, an algorithm is described to check that a given divisor is ample. Using a computer program called Nef Wizard, written by Daniel Krashen (http://www.yale.edu/users/dkrashen/nefwiz), one can use the criteria and the algorithm to verify the conjecture for low genus. This is done on $\M_g$ for $g \le 24$, more than doubling the known cases of the conjecture and showing it is true for the first genus such that $\M_g$ is known to be of general type.

description: The polarized spin structure functions gp2 and gd2 have been measured at SLAC via the process of deep inelastic scattering. The data were collected over the kinematic range 0.02 ≤ x ≤ 0.8 and 0.7 (GeV/c)2 ≤ Q2 ≤ 20 (GeV/c) 2 by scattering 29.1 and 32.3 GeV longitudinally polarized electrons from transversely polarized 15NH3 and 6LiD targets. This is the first data set for gp2 with sufficient precision to differentiate between current theoretical models for the proton. The data show that gp2 is consistant with gWW2 as well as the bag model of Strattman and the Chiral model of Weigel while showing that it is inconsistent by several sigma with g 2 = 0 in the region x > 0.2. The absolute value of A2 is significantly smaller than the R positivity limit over the measured range and is also within the Soffer limit. The results for the twist-3 reduced matrix elements dp2 , dd2 and dn2 are also obtained. The Burkhardt-Cottingham sum rule integral and the Efremov-Leader-Taryaev sum rule integral are reported for the experimental kinematic range.

description: We construct the most general non-extremal deformation of the D-instanton solution with maximal rotational symmetry. The general non-supersymmetric solution carries electric charges of the SL(2,R) symmetry, which correspond to each of the three conjugacy classes of SL(2,R). Our calculations naturally generalise to arbitrary dimensions and arbitrary dilaton couplings. We show that for specific values of the dilaton coupling parameter, the non-extremal instanton solutions can be viewed as wormholes of non-extremal Reissner-Nordström black holes in one higher dimension. We extend this result by showing that for other values of the dilaton coupling parameter, the non-extremal instanton solutions can be uplifted to non-extremal non-dilatonic p-branes in p+1 dimensions higher. Finally, we attempt to consider the solutions as instantons of (compactified) type IIB superstring theory. In particular, we derive an elegant formula for the instanton action. We conjecture that the non-extremal D-instantons can contribute to the R^8-terms in the type IIB string effective action.

Individuato nelle grandi nubi di gas della galassia Ngp–190387 sotto forma di acido fluoridrico, il fluoro non era mai stato osservato in un ambiente di formazione stellare così antico, risalente a quando l’universo aveva appena il 10 per cento della sua età attuale. Ciò implica che le stelle nel cui nucleo è stato sintetizzato devono essere vissute e morte rapidamente: stelle di tipo Wolf-Rayet, suggeriscono gli autori dello studio pubblicato oggi su Nature Astronomy

description: This paper formally compares the fit of various versions of the incomplete markets model with aggregate uncertainty, relying on a simple Bayesian empirical framework. The models differ in the degree of households’ heterogeneity, with a focus on the role of preferences. For every specification, empirically motivated priors for the parameters are postulated to obtain the models’ predictive distributions, which are interpreted as being the distributions of population moments. These are in turn contrasted with the posterior distributions of the same moments obtained from an atheoretical (Bayesian) econometric model. It is shown that aggregate data on consumption and income contain valuable information to determine which models are more likely to have generated the data. In particular, despite its generality, a model with both risk aversion and discount factor heterogeneity displays a very low marginal likelihood, and should not be employed for the design of macroeconomic policies and welfare analysis. It is also found that the other models display similar posterior odds, with the Bayes factors ranging between 1 and 3. Finally, it is shown that practitioners in the field should carefully calibrate the values of the unemployment rate in booms and expansions, as they heavily affect the autocorrelation of aggregate consumption and the correlation between consumption and income. This finding suggests that the magnitude of welfare effects computations is likely to be influenced considerably by these two parameters.

description: Quantum absorption refrigerator (QAR) autonomously extracts heat from a cold bath and dumps into a hot bath by exploiting the input heat from a higher temperature reservoir. QARs typically require three-body interactions. We propose and examine a two-body QAR model based upon optomechanical-like coupling in the working medium composed of either two two-level systems or two harmonic oscillators or one two-level atom and a harmonic oscillator. In the ideal case without internal dissipation, within the experimentally realizable parameters, our model can attain the coefficient of performance that is arbitrarily close to the Carnot bound. We study the efficiency at maximum power, a bound for practical purposes, and show that by using suitable reservoir engineering and exploiting the nonlinear optomechanial-like coupling, one can achieve efficiency at maximum power close to the Carnot bound, though the power gradually approaches to zero as the efficiency approaches the Carnot bound. Moreover, we discuss the impact of non-classical correlations and the size of Hilbert space on the cooling power. Finally, we consider a more realistic version of our model in which we consider heat leaks that makes QAR non-ideal and prevent it to achieve the Carnot efficiency.
