description: This study examined the extent to which dyadic communication apprehension (CA) manifested in heart-rate (HR; index of sympathetic activity) and heart-rate variability (HRV; index of parasympathetic [vagal] activity) during dyadic interaction and explored the inhibiting role of self-esteem for dyadic-communication distress through two explanatory frameworks: A moderation and an indirect effect. Participants first completed self-report measures for dyadic CA and self-esteem. Their cardiac activity was then monitored in a noncommunicative period and then while engaging in impromptu dyadic communication. Results indicated that during interaction, higher dyadic CA manifests strongly in higher HR and lower HRV. Dyadic CA manifested in HR independently of HRV differences, suggesting dyadic CA prompts substantial cardiac acceleration through sympathetic influences given that this effect is not dependent on vagal activity. Dyadic CA also manifested in lower HRV independently of HR differences, substantiating the direct impact that dyadic CA has on vagally mediated cardiac dysregulation. Together, these results suggested that dyadic CA induces psycho-cardiac distress two ways, prompting arousal via sympathetic input and dysregulation via parasympathetic withdrawal. Regarding self-esteem, there was tentative evidence of a moderating effect for the impact of dyadic CA on HR, but not on HRV. Tests of indirect effects showed significant evidence of its inhibitory influence on both distress symptoms via dyadic CA. Findings are interpreted in the context of arousal and emotion regulation when navigating one-on-one conversations.

description: The ratios among the leading-order (LO) hadronic vacuum polarization (HVP) contributions to the anomalous magnetic moments of electron, muon and tau-lepton, $a_{\ell=e,μτ}^{HVP,LO}$, are computed using lattice QCD+QED simulations. The results include the effects at order $O(α_{em}^2)$ as well as the electromagnetic and strong isospin-breaking corrections at orders $O(α_{em}^3)$ and $O(α_{em}^2(m_u-m_d))$, respectively, where $(m_u-m_d)$ is the $u$- and $d$-quark mass difference. We employ the gauge configurations generated by the Extended Twisted Mass Collaboration with $N_f=2+1+1$ dynamical quarks at three values of the lattice spacing ($a \simeq 0.062, 0.082, 0.089$ fm) with pion masses in the range 210 - 450 MeV. We show that in the case of the electron-muon ratio the hadronic uncertainties in the numerator and in the denominator largely cancel out, while in the cases of the electron-tau and muon-tau ratios such a cancellation does not occur. For the electron-muon ratio we get $R_{e/μ} \equiv (m_μ/m_e)^2 (a_e^{HVP,LO} / a_μ^{HVP,LO}) = 1.1456~(83)$ with an uncertainty of $\simeq 0.7 \%$. Our result, which represents an accurate Standard Model (SM) prediction, agrees very well with the estimate obtained using the results of dispersive analyses of the experimental $e^+ e^- \to$ hadrons data. Instead, it differs by $\simeq 2.7$ standard deviations from the value expected from present electron and muon (g - 2) experiments after subtraction of the current estimates of the QED, electro-weak, hadronic light-by-light and higher-order HVP contributions, namely $R_{e/μ} = 0.575~(213)$. An improvement of the precision of both the experiment and the QED contribution to the electron (g - 2) by a factor of $\simeq 2$ could be sufficient to reach a tension with our SM value of the ratio $R_{e/μ}$ at a significance level of $\simeq 5$ standard deviations.

description: We study horizon shells and soldering freedom for extreme black holes and how supertranslation-like Bondi-Metzner-Sachs (BMS) symmetries appear as soldering transformations. Further, for a null shell placed infinitesimally close to the horizon of an extreme Reissner-Nordstr$\ddot{o}$m (RN) black hole, we show superrotation-like symmetries also arise as soldering freedom. Next, considering the interaction of impulsive gravitational waves supported at the horizon shell with test particles, we study how the "memory" (or the imprints) of BMS-like symmetries gets encoded in the geodesics (test particles) crossing the shell. Our study shows, timelike test particles get displaced from their initial plane when they cross the horizon shell. For a null geodesic congruence crossing the horizon shell, the optical tensors corresponding to the congruence suffer jumps. In both the cases, the changes are induced by BMS parameters that constitute the gravity wave and matter degrees of freedom of the shell.

title: The development of children's ability to recognize facial emotion
Creators: name: Mount, Hazel Florence
Publisher: name: The Open University
Year: 1981

description: This study investigated the development among 3 1/2 to 11 year old children of the ability to recognize six common emotions (Happiness, Disgust, Sadness, Anger, Surprise and Fear), using a procedure which employed six standard photographs (of male and female faces and of parts o f the female face) accompanied by illustrative short stories. Additionally,children's ability to match photographs on the basis of emotion expression was examined and compared with performance on the recognition task. The relationship between recognition of facial emotion and age, social class, sex, popularity with peers, extraversion and neuroticism, birth order and the presence or absence of siblings was also investigated. Individual testing of children aged 3 1/2 to 6 was employed, and a procedure was developed for group testing of older children. The results confirmed that accuracy of recognition of emotion increases with age. Social class differences emerged on recognition of emotion in the male and female face,and in parts of the face (excluding the nose). Only in recognition of emotion in eyes did girls perform more accurately than boys. Accuracy of recognition correlated significantly with popularity with peers except in judgments of emotion in the eyes. Extraversion was significantly correlated with accuracy of recognition of emotion in the female face and eyes. Presence or absence of siblings was not significantly related to emotion recognition, but later born children recognized emotion in noses more accurately than first born children. It was also demonstrated that children's ability to match emotion expressions emerges before their ability to recognize the expressions. Analysis of errors showed that the pattern of errors made in emotion recognition was similar to that found in emotion recognition studies with adults. The errors in emotion matching reflected those found in recognition. However, there were also common confusions in matching which were found in emotion recognition by the younger children, but not among older children in the present study, or in the adult studies.

description: Exoplanets orbiting M dwarfs present a valuable opportunity for their detection and atmospheric characterisation. This is evident from recent inferences of H$_2$O in such atmospheres, including that of the habitable-zone exoplanet K2-18b. With a bulk density between Earth and Neptune, K2-18b may be expected to possess a H/He envelope. However, the extent of such an envelope and the thermodynamic conditions of the interior remain unexplored. In the present work, we investigate the atmospheric and interior properties of K2-18b based on its bulk properties and its atmospheric transmission spectrum. We constrain the atmosphere to be H$_2$-rich with a H$_2$O volume mixing ratio of $0.02-14.8$%, consistent with previous studies, and find a depletion of CH$_4$ and NH$_3$, indicating chemical disequilibrium. We do not conclusively detect clouds/hazes in the observable atmosphere. We use the bulk parameters and retrieved atmospheric properties to constrain the internal structure and thermodynamic conditions in the planet. The constraints on the interior allow multiple scenarios between rocky worlds with massive H/He envelopes and water worlds with thin envelopes. We constrain the mass fraction of the H/He envelope to be $\lesssim 6$%; spanning $\lesssim 10^{-5}$ for a predominantly water world to $\sim6$% for a pure iron interior. The thermodynamic conditions at the surface of the H$_2$O layer range from the super-critical to liquid phases, with a range of solutions allowing for habitable conditions on K2-18b. Our results demonstrate that the potential for habitable conditions is not necessarily restricted to Earth-like rocky exoplanets.

EXAMINING PROTEIN-PROTEIN INTERACTIONS AND THEIR ROLE IN THE TRANSCRIPTIONAL REGULATION OF THE FLORAL ORGANS OF ARABIDOPSIS THALIANA
Creators: name: Wokasch, Anthony
Publisher: name: American University
Year: 2023

description: In this study, the organism Arabidopsis thaliana, a known model of floral development, is used to outline the combinatorial role that multiple genes and their proteins play in the regulation and specificity of each floral organ. The ABCE homeotic floral organ identity genes are responsible for the specification of floral organ fate in each whorl of the flower. Other genes known as boundary genes are characterized to uphold the boundaries between whorls by regulating the expression of the identity genes. This study examines the boundary genes known as SUPERMAN (SUP) and RABBIT EARS (RBE) and their interactions with other proteins to achieve a mechanism of transcriptional repression resulting in proper floral organ development and patterning. We demonstrate that the corepressor TOPLESS (TPL) interacts with SUP through its EAR motif and that a fully intact EAR motif is required for this interaction to occur. Additionally, our findings suggest that this SUP-TPL interaction is responsible for upholding the boundary between whorls 3 and 4 by repressing the expression of the B-class genes AP3 and PI in the innermost whorl. Overall, this study can lead to a better understanding of how specific mechanisms of transcriptional regulation are used to maintain the function of stem cell populations for proper organ specification and development in all eukaryotes.

description: AGN activity is known to drive fast outflows of gas. We report the discovery of fast outflows of neutral gas with velocities over 1000 km/s in a number of radio galaxies. In the best studied object, 3C~293, the kinematical properties of the neutral and ionised outflows are similar, indicating a common origin. Moreover, the outflow appears to be located near the radio lobes and not near the nucleus. This suggests that the interaction between the radio jet and the ISM is driving the outflow.

description: Recent intense X-ray and UV monitoring campaigns with Swift have detected clear UV lags behind X-ray in several local active galactic nuclei (AGNs). The UV to X-ray lags are often larger (by a factor up to ~ 20) than expected if the UV variation is simply due to the X-ray reprocessing. We previously developed a model in which the UV/optical variations are attributed to disk turbulences, and the effect of large-scale turbulence is considered. Our model, which overcomes many severe challenges to the reprocessing scheme, can well explain the observed variations in NGC 5548, particularly the correlations and lags among the UV/optical bands. In this work, assuming the corona heating is associated with turbulences in the inner accretion disk, we extend our study to model the correlations and lags between the X-ray and UV/optical bands. We find that our model, without the need of light echoing, can well reproduce the observed UV to X-ray lags and the optical to UV lags simultaneously in four local Seyfert galaxies, including NGC 4151, NGC 4395, NGC 4593, and NGC 5548. In our scenario, relatively larger UV to X-ray lag is expected for AGN with smaller innermost disk radius and thus more compact corona. Interestingly, for these Seyfert galaxies studied in this work, sources with relatively larger UV to X-ray lags do have broader Fe Ka lines, indicative of relativistic broadening due to more compact corona and smaller innermost disk radius. If confirmed with more X-ray and UV monitoring campaigns, this interesting discovery would provide a new probe to the inner disk/corona.

title: The chromatic index of simple graphs
Creators: name: Fiorini, S
Publisher: name: The Open University
Year: 1975

description: The object of this thesis is twofold: (i) to study the structural properties of graphs which are critical with respect to edge-colourings; (ii) to apply the results obtained to the classification problem arising from Vizing's Theorem. Chapter 1 contains a historical, non-technical introduction, general graph-theoretic definitions and notation, a discussion of Vizing's Theorem as well as a survey of the main results obtained to date in Vizing's classification problem. Chapter 2 introduces the notion of criticality in the first section; the second section contains both well-known and new constructions of critical graphs which will be used in later chapters. The third and final section contains new results concerning elementary properties of critical graphs. Chapter 3 deals with uniquely-colourable graphs and their relationship to critical graphs. Chapter 4 contains results on the connectivity of critical graphs, whereas Chapter 5 deals with bounds on the number of edges of these graphs. In particular, bounds improving those given by Vizing are presented. These results are applied to problems concerning planar graphs. In Chapter 6, critical graphs of small order are discussed. All such graphs of order at most 8 are determined, while the 'critical graph conjecture’ of Beineke & Wilson and Jakobsen is shown to be true for all graphs on at most 10 vertices. The seventh and final chapter deals with circuit length properties of critical graphs. In particular, the minimal order of certain critical graphs with given girth and maximum valency is determined. Results improving Vizing’s estimate of the circumference of critical graphs are also given. The Appendix includes a computer programme which generates critical graphs from simpler ones using a constructive algorithm given in Chapter 2.

Post-Newtonian Freely Specifiable Initial Data for Binary Black Holes in Numerical Relativity

Year: 2005
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Construction of astrophysically realistic initial data remains a central problem when modelling the merger and eventual coalescence of binary black holes in numerical relativity. The objective of this paper is to provide astrophysically realistic freely specifiable initial data for binary black hole systems in numerical relativity, which are in agreement with post-Newtonian results. Following the approach taken by Blanchet, we propose a particular solution to the time-asymmetric constraint equations, which represent a system of two moving black holes, in the form of the standard conformal decomposition of the spatial metric and the extrinsic curvature. The solution for the spatial metric is given in symmetric tracefree form, as well as in Dirac coordinates. We show that the solution differs from the usual post-Newtonian metric up to the 2PN order by a coordinate transformation. In addition, the solutions, defined at every point of space, differ at second post-Newtonian order from the exact, conformally flat, Bowen-York solution of the constraints.

description: Here we report the first detection of polarization signals induced by the Zeeman effect in spectral lines of the E^4Π-A^4Πsystem of FeH located around 1.6 $μ$m. Motivated by the tentative detection of this band in the intensity spectrum of late-type dwarfs, we have investigated the full Stokes sunspot spectrum finding circular and linear polarization signatures that we associate with the FeH lines of the E^4Π-A^4Πband system. We investigate the Zeeman effect in these molecular transitions pointing out that in Hund's case (a) coupling the effective Landé factors are never negative. For this reason, the fact that our spectropolarimetric observations indicate that the Landé factors of pairs of FeH lines have opposite signs, prompt us to conclude that the E^4Π-A^4Πsystem must be in intermediate angular momentum coupling between Hund's cases (a) and (b). We emphasize that theoretical and/or laboratory investigations of this molecular system are urgently needed for exploiting its promising diagnostic capabilities.

Neutrino masses from beta decays after KamLAND and WMAP (Updated including the NC enhanced SNO data)

description: The first data released by the KamLAND collaboration have confirmed the strong evidence in favour of the LMA solution of the solar neutrino problem. Taking into account the ranges for the oscillation parameters allowed by the global analysis of the solar, CHOOZ and KamLAND data, we update the limits on the neutrinoless double beta decay effective neutrino mass parameter and analyze the impact of all the available data from neutrinoless double beta decay experiments on the neutrino mass bounds, in view of the latest WMAP results. For the normal neutrino mass spectrum the range (0.05-0.23) eV is obtained for the lightest neutrino mass if one takes into account the Heidelberg-Moscow evidence for neutrinoless double beta decay and the cosmological bound. It is also shown that under the same conditions the mass of the lightest neutrino may not be bounded from below if the spectrum is of the inverted type. Finnaly, we discuss how future experiments can improve the present bounds on the lightest neutrino mass set by the Troitsk, Mainz and WMAP results. In the addendum we update the allowed ranges for the effective Majorana neutrino mass parameter in view of the latest NC enhanced SNO data.

A Derivation of the Pythagorean Won-Loss Formula in Baseball
Creators: name: Miller, Steven J.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Statistics Theory (math.ST)
subject: History and Overview (math.HO)
subject: FOS: Mathematics

description: It has been noted that in many professional sports leagues a good predictor of a team's won-loss percentage is Bill James' Pythagorean Formula RSobs^c / (RSobs^c + RAobs^c), where RSobs (resp. RAobs) is the observed average number of runs scored (allowed) per game and c is a constant for the league; for baseball the best agreement is when c is about 1.82. We provide a theoretical justification for this formula and value of c by modelling the number of runs scored and allowed in baseball games as independent random variables drawn from Weibull distributions with the same b and c but different a; the probability density f(x;a,b,c) is 0 for x < b and is (c/a) ((x-b)/a)^{c-1} exp(-((x-b)/a)^c) otherwise. This model leads to a predicted won-loss percentage of (RS-b)^c / ((RS-b)^c + (RA-b)^c); here RS (resp. RA) is the mean of the random variable corresponding to runs scored (allowed), and RS - b (resp. RA - b) is an estimator of RSobs (resp. RAobs). An analysis of the 14 American League teams from the 2004 baseball season shows that (1) given that the runs scored and allowed in a game cannot be equal, the runs scored and allowed are statistically independent; (2) the best fit Weibull parameters attained from a least squares or a maximum likelihood analysis give good fits; least squares gives a mean value of c of 1.79 with a standard deviation of .09, and maximum likelihood gives a mean value of c of 1.74 with a standard deviation of .06, which agree beautifully with the observed best value of 1.82 attained by fitting RSobs^c / (RSobs^c + RAobs^c) to the observed winning percentages.
description: 13 pages, 10 figures, 4 tables (second revised version: some typos corrected, further analysis of whether or not runs scored and allowed are independent. the correct phrasing is: given that runs scored and allowed must be distinct integers, they are statistically independent.)

title: The development of small craft-based businesses in Scotland
Creators: name: Brown, Douglas C.J.
Publisher: name: The Open University
Year: 1981

description: As it had been found that there was little authoritative published evidence regarding the crafts in Scotland, this research programme was initiated in 1975 to rectify that situation. The subjects were broadly defined as being self-employed, engaged in all aspects of the craft business and within the range of skills and creativity which combine to form the commonly accepted basis of a craft. Within the overall objective, emphasis was placed on the identification of the craftsmen and craft businesses, of the influences upon them and on the general trends. From the combined results it was anticipated that development potential might be assessed. The co-operation of bodies such as the Scottish Development Agency was sought and received, providing invaluable source material, and leading to the development of an index of craft businesses. That index, up-dated annually throughout the four-year period of research, was the basis for analysis of elements such as the movements in craft population, physical distribution and the numerical strengths of the individual crafts. Such analysis established a clear relationship between the location of craft businesses and population density, found the largest craft groups to be ceramics, silversmithing and jewellery and weaving, and identified an increase in the craft business population between 1975 and 1977 and a decrease in 1978. A pilot survey in 1976 confirmed the feasibility of a survey which was conducted in 1977. The survey results established the importance of these businesses in terms of employment and contribution, and identified the strong characteristics of independence and personal association with the craft on the part of the proprietors. The principal influences externally were found to be those exerted by market forces, the attitudes adopted by the retail trade, the policies adopted by government agencies responsible for the crafts, and internally by the background training, experience and motivation of the proprietor. It was found, despite the rich variety of backgrounds and the lack of training and experience of many, that there were insufficient features which could adequately distinguish the performance potential in a business at this point in time. The strategy being adopted by the Scottish Development Agency, as one of the principal planners and administrators for the crafts, of directing assistance towards entrants with assessable levels of training and of exerting pressure towards improved standards, was noted. It was therefore concluded that an alternative staged strategy should be adopted - of improving basic knowledge of factors such as the reasons for failure in business; of providing a broad base of assistance in the initial stages of a business with more specialised and appropriate assistance being made available as the business develops according to the capability and motivation of the proprietor.

We also approach the back-reaction problem as a second-order calculation in perturbation theory finding no evidence that the back-reaction of cosmological fluctuations is a gauge artifact. In agreement with the results on the EMT, the average expansion rate is decreased by the back-reaction of cosmological fluctuations.

description: We extend dilaton chiral perturbation theory (dChPT) to include the taste splittings in the Nambu--Goldstone sector observed in lattice simulations of near-conformal theories with staggered fermions. We then apply dChPT to a recent simulation by the LSD collaboration of the SU(3) gauge theory with 8 fermions in the fundamental representation, which is believed to exhibit near-conformal behavior in the infrared, and in which a light singlet scalar state, nearly degenerate with the pions, has been found. We find that the mesonic sector of this theory can be successfully described by dChPT, including, in particular, the mesonic taste splittings found in the simulation. We confirm that current simulations of this theory are in the "large-mass" regime.

SPATIAL HABITAT PARAMETERS AND EFFECTS OF HABITAT FRAGMENTATION ON HYPOTELMINORHEIC FAUNA IN SEEPAGE SPRINGS IN SOUTHEAST WASHINGTON, DC
Creators: name: Burch, Elizabeth
Publisher: name: American University
Year: 2023

description: The hypotelminorheic is a shallow subterranean habitat that is groundwater fed and home to aquatic, troglomorphic animals which have a limited range and low occupancy at each site. This study explored the spatial parameters of the seep habitat and nearby fragmentation, at two spatial scales, with the goal of defining what makes the habitat suitable, especially for isopods and amphipods. Using ArcMap, spatial, surface, and fragmentation variables were calculated and added at each georeferenced point where sampling occurred in the small parklands of southeast Washington, DC. At the land patch scale, only forest cover and the number of seeps on an uninterrupted land patch could predict patch occupancy. At the seeps scale, the animals were not very edge avoidant, but geologic and surface features predicted seep occupancy. Removing forest cover is a threat to the habitat, and larger protected parklands would allow for more seeps on each patch of land.

description: While low-luminosity galaxies dominate number counts at all redshifts, their contribution to cosmic Reionization is poorly understood due to a lack of knowledge of their physical properties. We isolate a sample of 35 z~4-5 continuum-faint Lyman-alpha emitters from deep VLT/MUSE spectroscopy and directly measure their Halpha emission using stacked Spitzer/IRAC Ch. 1 photometry. Based on Hubble Space Telescope imaging, we determine that the average UV continuum magnitude is fainter than -16 (~0.01 L_star), implying a median Lyman-alpha equivalent width of 249 Angstroms. By combining the Halpha measurement with the UV magnitude we determine the ionizing photon production efficiency, xi_ion, a first for such faint galaxies. The measurement of log (xi_ion [Hz/erg]) = 26.28 (+0.28; -0.40) is in excess of literature measurements of both continuum- and emission line-selected samples, implying a more efficient production of ionizing photons in these lower-luminosity, Lyman-alpha-selected systems. We conclude that this elevated efficiency can be explained by stellar populations with metallicities between 4e-4 and 0.008, with light-weighted ages less than 3 Myr.

Regularization of spherically symmetric evolution codes in numerical relativity

description: The lack of regularity of geometric variables at the origin is often a source of serious problem for spherically symmetric evolution codes in numerical relativity. One usually deals with this by restricting the gauge and solving the hamiltonian constraint for the metric. Here we present a generic algorithm for dealing with the regularization of the origin that can be used directly on the evolution equations and that allows very general gauge choices. Our approach is similar in spirit to the one introduced by Arbona and Bona for the particular case of the Bona-Masso formulation. However, our algorithm is more general and can be used with a wide variety of evolution systems.

Periodicity of superconducting shape resonances in thin films

description: The pairing temperature of superconducting thin films is expected to display, within the Bardeen-Cooper-Schrieffer theory, oscillations as a function of the film thickness. We show that the pattern of these oscillations switches between two different periodicities at a density-dependent value of the superconducting coupling. The transition is most abrupt in the anti-adiabatic regime, where the Fermi energy is less than the Debye energy. To support our numerical data, we provide new analytical expressions for the chemical potential and the pairing temperature as a function of thickness, which only differ from the exact solution at weak coupling by exponentially-small corrections.

Community Structure in Jazz

description: Using a database of jazz recordings we study the collaboration network of jazz musicians. We define the network at two different levels. First we study the collaboration network between individuals, where two musicians are connected if they have played in the same band. Then we consider the collaboration between bands, where two bands are connected if they have a musician in common. The community structure analysis reveals that these constructions capture essential ingredients of the social interactions between jazz musicians. We observe correlations between recording locations, racial segregation and the community structure. A quantitative analysis of the community size distribution reveals a surprising similarity with an e-mail based social network recently studied.

Antiferroelectricity in a family of pyroxene-like oxides with rich polymorphism

description: Antiferroelectrics have potential applications in energy conversion and storage, but are scarce, particularly among oxides that otherwise display rich ferroic behaviours. Are we overlooking potential antiferroelectrics, simply because we have not discovered their corresponding ferroelectric phase yet? Here we report a first-principles study suggesting this is the case of a family ABO$_3$ pyroxene-like materials, characterized by chains of corner-sharing BO$_4$ tetrahedra, a well-known member being KVO$_3$. The irregular tetrahedra have an electric dipole associated to them. In the most stable polymorph, the dipoles display an antipolar pattern with zero net moment. However, upon application of an electric field, half of the tetrahedra rotate, flipping the corresponding dipoles and reaching a ferroelectric state. We discuss the unique possibilities for tuning and optimization these antiferroelectrics offer. We argue that the structural features enabling this antiferroelectric behaviour are also present in other all-important mineral families.

CHARACTERIZING THE NEUROCHEMICAL, PHYSIOLOGICAL AND BEHAVIORAL EFFECTS OF THE SYNTHETIC CATHINONE α-PYRROLIDINOPENTIOPHENONE (α-PVP)

description: α-pyrrolidinopentiophenone (α-PVP, Flakka) is a synthetic cathinone that is highly addictive and poses serious risks to the user’s mental and physical health. Despite these dangers, α-PVP remains largely unstudied. The abuse potential of a drug (i.e., its likelihood of self-administration) is dependent upon the balance of the drug’s rewarding and aversive effects and while α-PVP has begun to be studied for these effects, factors that impact them have received little attention. In this context, the goal of these experiments was to further characterize α-PVP by evaluating neurochemical (stereochemistry; Experiment 1), subject (sex; Experiment 2) and experiential (drug history; Experiment 3) factors impacting the affective properties of α-PVP. For Experiments 1A, 2, and 3, the aversive (conditioned taste avoidance (CTA), body temperature, locomotor activity and stereotypies) and rewarding (conditioned place preference (CPP)) effects of α-PVP were investigated. Experiment 1B assessed uptake inhibition of the brain amines, dopamine and norepinephrine. Results: In Experiment 1A, the S-enantiomer of α-PVP mediated the aversive effects of the racemate (in each: CTA, temperature and activity) in male Sprague Dawley (SD) rats at all doses tested. Uptake assessments (Experiment 1B) showed that the R-enantiomer was active, but less potent than the S-enantiomer and racemate. In Experiment 2, male SD rats displayed greater effects of α-PVP than females both in CPP and CTA. Males had a faster onset of temperature effects and had a longer duration of action than females, while females displayed greater locomotor activity than males (although males displayed greater stereotypies than females). In Experiment 3, ethanol pre-exposure attenuated taste avoidance but did not affect reward, which could increase abuse liability. Ethanol pre-exposure increased the locomotor effects of α-PVP (at 3 mg/kg) but had no effect on thermoregulation or stereotypies. The present data indicate that the rewarding and aversive effects of α-PVP are dependent upon its stereochemistry and significantly affected by sex and an ethanol drug history. While these findings lay initial groundwork in characterizing the aversive and rewarding effects of α-PVP, future studies assessing the effects of these properties on intravenous self-administration will be necessary to predict the abuse liability of α-PVP.
