Campus Sex Courts: Beyond a Reasonable Doubt
Creators: name: Davis, John
Publisher: name: figshare
Year: 2020
Subjects: Education

description: Many experts mistakenly believe that proving culpability beyond a reasonable doubt is only necessary in criminal-court trials. However, the United States Supreme Court has ruled otherwise (as have many courts in many jurisdictions). There is no other determination made in our culture that has more grave social consequences on a person than an accusation of sexual misconduct. These severe consequences, impairment of liberty and property, as well as a lifelong stigma as a sex offender, compel high standards of due process, according to Supreme Court rulings, in making such a determination against accused persons. This article comments on the Department of Education’s proposed rulemaking on campus adjudications of Title IX proceedings, especially those pertaining to sexual misconduct or sexual harassment.
Natural attenuation of acqueous zinc in shallow soils over permafrost downslope of Galkeno 300 Mine Adit, United Keno Hill Mines, Central Yukon
Creators: name: MacGregor, Dylan B.
Publisher: name: University of British Columbia
Year: 2009

description: This study investigated the natural attenuation of zinc in mine drainage at the Galkeno 300 mine site, located at the northern limit of the discontinuous permafrost zone in central Yukon Territory. The mine drainage contains -150 mg/1 Zn where it exits the mine; where these same waters enter the receiving environment of Christal Creek, the Zn concentrations have been reduced to ~2 mg/1. The research program examining this natural attenuation consisted of two phases. Phase 1 was comprised of a site investigation along with the collection of samples for chemical analyses and laboratory testing. Phase 2 consisted of laboratory characterisation and testing of samples collected during Phase 1. The Phase 1 site investigation was carried out during summer 2000. A climate station was established to monitor precipitation and temperature during the study-period. Site water balance was monitored through the erection of two weirs; inputs exceeded outputs by and average of 16%, indicating a minor degree of dilution. Water samples collected at sites along the longitudinal mine drainage flowpath showed no temporal trends, but clearly outlined a dramatic decrease in Zn concentrations with distance from the adit. Soil samples of upper organic and lower mineral horizons were collected from within and immediately adjacent to the flowpath. Chemical analysis of aliquots of these samples clearly showed elevation of Zn concentrations in samples in contact with mine drainage; upper organic horizon samples in particular were found to contain highly anomalous Zn levels.

description: Resumen El presente trabajo tiene como objetivo elaborar un modelo teórico para explicar la intensidad de consumo de vino de calidad. Para la recogida de datos se ha realizado una encuesta a 50 profesionales de la restauración de la provincia de Alicante y una encuesta a 408 consumidores de vino de la misma provincia. El tratamiento estadístico de los datos se ha realizado mediante análisis de ecuaciones estructurales, que ha permitido la construcción de las variables latentes explicativas de la intensidad de consumo, así como la cuantificación de la influencia de cada uno de esos constructos teóricos sobre la variable a explicar. Los resultados muestran que la variable con mayor influencia sobre la intensidad de consumo de vino de calidad es el interés por la gastronomía, seguida de la actividad social. La preocupación por la salud, al contrario de lo que puede extraerse de ciertas estrategias de comunicación, es una variable que influye negativamente sobre la intensidad de consumo, esto es, cuanto mayor es la preocupación por la salud del consumidor, menor es su intensidad de consumo. Palabras clave: vino de calidad, modelos ecuaciones estructurales, frecuencia de consumo Summary The aim of this work is the design of a theoretical model that explains quality wine consumption frequency. To collect the data, two surveys were carried out: the first one to 50 hostel professionals from Alicante, and the second one to 408 wine consumers from the same region. Structural equation models was used to estimate the model. This method allows for the construction of independent latent (unobserved) variables which influence consumption intensity. Moreover, this analysis permit the quantification of the influence of the theoretical constructs over the dependent variable. The results show that the variable that influence the most over quality wine consumption intensity is the "interest in gastronomy", followed by the "social activity". The "worry about health" has a negative influence over consumption intensity, that is, the highest worry about health, the lowest consumption intensity.

description: RESUMEN - La reforma de la Política Agrícola Común (PAC) de la Agenda 2000, justifica la intervención pública como medio de consecución de dos objetivos fundamentales: potenciar la competitividad de la agricultura europea y defender su carácter multifuncional. Este artículo trata de analizar el grado de consecución del primero de estos objetivos, en su doble vertiente de adopción de nuevas tecnologías productivas y de reforma estructural. Para ello se han construido sendos modelos de programación matemática con los que se simulan los efectos de la adopción de diferentes innovaciones tecnológicas sobre explotaciones tipo de dos comarcas agrícolas españolas (Tierra de Campos de Valladolid y Campiña Baja de Córdoba). Junto con la Agenda 2000 y su situación previa, se estudian los efectos de otros tres escenarios alternativos de política agraria. Los resultados relativos de estos escenarios permiten evaluar el incentivo que cada sistema de intervención introduce sobre los procesos de adopción de nuevas tecnologías y de reforma estructural. SUMMARY - The Agenda 2000 reform of the Common Agricultural Policy (CAP) justifies public intervention in agriculture in the basis of two main objectives: increasing the competitiveness of European agriculture and its multifunctional role. This paper attends to assess the ability of the reform to address this first objective. Competitiveness is considered both as the capacity to adopt new technologies and to restructure land holdings towards those more efficient. Mathematical programming models simulating the adoption of new technologies by selected representative farms have been constructed for two Spanish agricultural areas - Tierra de Campos of Valladolid and Campiña Baja of Córdoba. The simulation has included not only Agenda 2000 and the previous intervention system, but also three alternative policy scenarios. Relative results between scenarios allow to evaluate the size of the incentive introduce by each intervention system to adopt new technologies or promote structural reforms.

description: Paper presented at the Spring Technical Meeting of the Eastern States Section of the Combustion Institute, March 4–7 2018, State College PA.
Yield Sooting Index (YSI) was determined for 13 oxygen-containing aromatic compounds by measuring line-of-sight spectral radiance (LSSR) in a laminar non-premixed methane/air flame doped with 1000 ppm of each compound. The compounds included anisole (methoxybenzene), other aromatic ethers, and phenols. The presence of oxygen greatly reduced soot formation in some cases, but increased it in others. Thus oxygenated aromatics are potentially valuable as fuel components with intrinsically low particulate emissions, but the specific structure is important. Compounds containing an aromatic ring with an adjacent oxygen atom tended to have a lower sooting tendency than did compounds with oxygen atoms elsewhere in the side chain. This observation was quantitatively explored using Density Functional Theory (DFT) calculations. The bond dissociation energies for nine aromatic hydrocarbons and oxygenates were calculated using GGA B3LYP density functions with 6-31G(d) basis sets. When possible, unimolecular dissociation to phenoxy radical was favored and resulted in much lower YSIs than similar compounds where the oxygen atom was not adjacent to the aromatic ring. Structures that dissociated to benzyl radical had much higher sooting tendencies, sometimes by over a factor of two in comparison to phenoxy- forming compounds.

Anisotropy of the cosmic gamma-ray background from dark matter annihilation

description: High-energy photons from dark matter annihilation contribute to the cosmic gamma-ray background (CGB). Since dark matter particles are weakly interacting, annihilation can happen only in high density regions such as dark matter halos. The precise shape of the energy spectrum of CGB depends on the nature of dark matter particles, as well as the cosmological evolution of dark matter halos. In order to discriminate between the signals from dark matter annihilation and other astrophysical sources, however, the information from the energy spectrum may not be sufficient. We show that dark matter annihilation also produces a characteristic anisotropy of the CGB, which provides a powerful tool for testing the origin. We develop the formalism based on a halo model approach to calculate the three-dimensional power spectrum of dark matter clumping, which determines the power spectrum of annihilation signals. We show that the sensitivity of future gamma-ray detectors such as GLAST should allow us to measure the angular power spectrum of CGB anisotropy, if dark matter particles are supersymmetric neutralinos and they account for most of the observed mean intensity of CGB in GeV region. On the other hand, if dark matter has a relatively small mass, and accounts for most of the CGB in MeV region, then the future Advanced Compton Telescope should be able to measure the anisotropy in MeV region. As the intensity of photons from annihilation is proportional to the density squared, we show that the predicted shape of the angular power spectrum of gamma rays from dark matter annihilation is different from that due to other astrophysical sources such as blazars. Therefore, the angular power spectrum of the CGB provides a smoking-gun signature of dark matter annihilation.

description: We present ISO mid-infrared spectrophotometry and far-infrared photometry of galaxies with Hidden Broad Line Regions (HBLR). We also present radiative transfer models of their spectral energy distributions which enable us to separate the contributions from the dusty disc of the AGN and the dusty starbursts. We find that the combination of tapered discs (discs whose thickness increases with distance from the central source in the inner part but stays constant in the outer part) and starbursts provide good fits to the data. The tapered discs dominate in the mid-infrared part of the spectrum and the starbursts in the far-infrared. After correcting the AGN luminosity for anisotropic emission we find that the ratio of the AGN luminosity to the starburst luminosity, L(AGN)/L(SB), ranges from about unity for IRAS14454-4343 to about 13 for IRAS01475-0740. Our results suggest that the warm IRAS colours of HBLR are due to the relatively high L(AGN)/L(SB). Our fits are consistent with the unified model and the idea that the infrared emission of AGN is dominated by a dusty disc in the mid-infrared and starbursts in the far-infrared.

These include macroscopic "vacuum" forces on a metallic layer in-between a dielectric medium and an inert ($ε(ω) = 1$) one. Ways to control the sign of these forces, based on dielectric properties of the media, are thus suggested. Finally, the large positive Casimir pressure, due to surface plasmons on thin metallic layers, is evaluated and discussed.

description: The Internet of Things (IoT) connected by Software Defined Networking (SDN) promises to bring great benefits to cyber-physical systems. However, the increased attack surface offered by the growing number of connected vulnerable devices and complex nature of SDN control plane applications could overturn the huge benefits of such a system. This paper addresses the vulnerability of some unspecified security flaw in the SDN control plane application (such as a zero-day software vulnerability) which can be exploited to insert malicious flow rules in the switch that do not match network policies. Specifically, we propose a blockchain-as-a-service (BaaS) based framework that supports switch flow verification and insertion; and additionally provides straightforward deployment of blockchain technology within an existing SDN infrastructure. While use of an external BaaS brings straightforward deployment, it obscures knowledge of the blockchain agents who are responsible for flow conformance testing through a smart blockchain contract, leading to potential exploitation. Thus, we design a strategy to prevent the blockchain agents from acting arbitrarily, as this would result in what is termed a "moral hazard". We achieve this by developing a novel mathematical model of the fair reward scheme based on game theory. To understand the performance of our system, we evaluate our model using a Matlab based simulation framework. The simulation results demonstrate that the proposed algorithm balances the needs of the blockchain agents to maximise the overall social welfare, i.e. the sum of profits across all parties.

description: An SPQR-tree is a data structure that efficiently represents all planar embeddings of a biconnected planar graph. It is a key tool in a number of constrained planarity testing algorithms, which seek a planar embedding of a graph subject to some given set of constraints. We develop an SPQR-tree-like data structure that represents all level-planar embeddings of a biconnected level graph with a single source, called the LP-tree, and give a simple algorithm to compute it in linear time. Moreover, we show that LP-trees can be used to adapt three constrained planarity algorithms to the level-planar case by using them as a drop-in replacement for SPQR-trees.

Durch Beeinflussung dieses TH2-Zytokinmilleus haben CD24hi CD38hi regulatorische B-Zellen möglicherweise einen protektiven Effekt auf die für das allergische Asthma bronchiale typische Obstruktion der Atemwege. Des Weiteren scheint ein Ungleichgewicht zwischen den proinflammatorischen non-Tregs einerseits und den immunsuppressiven rTregs und aTregs andererseits eine besondere Rolle in der Pathogenese der Erkrankung zu spielen.

description: The joint effect of the electron-phonon interaction and Kondo effect on the nonequilibrium transport through the single molecule transistor is investigated by using the improved canonical transformation scheme and extended equation of motion approach. Two types of Kondo phonon-satellites with different asymmetric shapes are fully confirmed in the spectral function, and are related to the electron spin singlet or hole spin singlet, respectively. Moreover, when a moderate Zeeman splitting is caused by a local magnetic field, the Kondo satellites in the spin resolved spectral function are found disappeared on one side of the main peak, which is opposite for different spin component. All these peculiar signatures that manifest themselves in the nonlinear differential conductance, are explained with a clear physics picture.

Hydraulic and design aspects of natural and constructed riffles in gravel-cobble bed rivers
Creators: name: Walker, Daniel Richard
Publisher: name: University of British Columbia
Year: 2009

description: The reintroduction of riffle-pool sequences has increasingly been promoted as an appropriate rehabilitation alternative for the re-naturalization of modified gravel-cobble bed channels. However, in the absence of hydraulic design guidelines, enhancement efforts often fail to evaluate the subsequent impacts to flood levels and sediment transport capacity. This has led to increased flooding and channel instability concerns. Accordingly, the intent of this thesis was to develop a hydraulic design procedure for the evaluation of the potential long-term hydraulic effects of riffle rehabilitation in uniform and degraded gravel-cobble bed rivers. Accordingly, a hydraulic analysis of natural and constructed riffle-pool sequences in four gravel-cobble bed streams was performed to investigate the variation in energy across constructed riffles at varying discharges up to and including bankfull. Significantly, riffle energy loss is shown to be substantial ranging between 50 and 100% of the total mini-reach loss. This indicates that the sampled rock-riffles are not being completely "drowned out" at higher stages, and that riffle-pool reconstruction may influence channel flow resistance, flood levels and sediment transporting capacity. Therefore, a comprehensive hydraulic analysis should be considered an essential component of rigorous riffle-pool rehabilitation design. A result of particular significance to the hydraulic design and analysis of rock-riffles is the strong relationship observed between riffle energy loss and amplitude for the rock-riffles sampled. This suggests the resultant rock-riffle energy loss in similar channels can be effectively described using a project-specific design variable. Drawing on this observation, an iterative procedure for the hydraulic design and analysis of rock-riffles in uniform or channelized gravel-cobble bed rivers is developed. Specifically, the procedure, which includes quantitative guidelines for the design of rock-riffle amplitude, spacing and stability, considers both the expectant energy loss and the potential effects on channel sediment transport capacity. This enables the creation of design channel profiles that better reflect the individual catchment and reach characteristics, the governing fluvial processes, and the specific rehabilitation goals and objectives. When used in association with appropriate geomorphic, hydraulic, hydrologic and ecologic appraisal, this new hydraulic analysis procedure should therefore provide a sound basis for the effective design and evaluation of riffle-pool rehabilitation projects in relatively steep gravel-cobble bed rivers

description: We consider electronic current transport through a ballistic one-dimensional quantum wire connected to two ferromagnetic leads. We study the effects of the spin-dependence of interfacial phase shifts (SDIPS) acquired by electrons upon scattering at the boundaries of the wire. The SDIPS produces a spin splitting of the wire resonant energies which is tunable with the gate voltage and the angle between the ferromagnetic polarizations. This property could be used for manipulating spins. In particular, it leads to a giant magnetoresistance effect with a sign tunable with the gate voltage and the magnetic field applied to the wire.

description: As heavy analog of graphene, plumbene is a two-dimensional material with strong spin-orbit coupling effects. Using scanning tunneling microscopy (STM), we observe that Pb forms a flat honeycomb lattice on an Fe monolayer on Ir(111). In contrast, without the Fe layer, a c(2x4) structure of Pb on Ir(111) is found. We use density functional theory (DFT) calculations to rationalize these findings and analyze the impact of the hybridization on the plumbene band structure. In the unoccupied states the splitting of the Dirac cone by spin-orbit interaction is clearly observed while in the occupied states of the freestanding plumbene we find a band inversion that leads to the formation of a topologically non-trivial gap. Exchange splitting as mediated by the strong hybridization with the Fe layer drives a quantum spin Hall to quantum anomalous Hall state transition.

description: We report magnetoresistance oscillations in high magnetic fields, B, up to 45 T and over a wide range of temperature in the Mott-like system Ca3Ru2O7. For B rotating within the ac-plane, slow and strong Shubnikov-de Haas (SdH) oscillations periodic in 1/B are observed for T≤1.5 K in the presence of metamagnetism. These oscillations are highly angular dependent and intimately correlated with the spin-polarization of the ferromagnetic state. For B||[110], oscillations are also observed but periodic in B (rather than 1/B) which persist up to 15 K. While the SdH oscillations are a manifestation of the presence of small Fermi surface (FS) pockets in the Mott-like system, the B-periodic oscillations, an exotic quantum phenomenon, may be a result of anomalous coupling of the magnetic field to the t2g-orbitals that makes the extremal cross-section of the FS field-dependent.

description: Cumulative probability distributions of income for management scenarios involving four pre-harvest marketing strategies are subjected to stochastic dominance analysis to determine risk-efficient sets of strategies for different groups of farmers in North Florida. Results indicate that farmers should behave differently in their choice of marketing strategies according to their risk attitudes. Highly risk-averse farmers should prefer some forward contracting while low risk-averse and risk loving farmers should prefer cash sales at harvest. Use of the futures markets leads to both higher income and greater risk than forward contracting but lower income and risk than cash sales.

description: A scheme for retrieving quantum information stored in collective atomic spin systems onto optical pulses is presented. Two off-resonant light pulses cross the atomic medium in two orthogonal directions and are interferometrically recombined in such a way that one of the outputs carries most of the information stored in the medium. In contrast to previous schemes our approach requires neither multiple passes through the medium nor feedback on the light after passing the sample which makes the scheme very efficient. The price for that is some added noise which is however small enough for the method to beat the classical limits.

description: We present a new numerical model to simulate settling trajectories of discretized individual or a mixture of particles of different geometrical shapes in a quiescent fluid and their flow trajectories in a flowing fluid. Simulations unveiled diverse particle settling trajectories as a function of their geometrical shape and density. The effects of the surface concavity of a boomerang particle and aspect ratio of a rectangular particle on the periodicity and amplitude of oscillations in their settling trajectories were numerically captured. Use of surrogate circular particles for settling or flowing of a mixture of non-circular particles were shown to miscalculate particle velocities by a factor of 0.9-2.2 and inaccurately determine the particles' trajectories. In a microfluidic chamber with particles of different shapes and sizes, simulations showed that steady vortices do not necessarily always control particle entrapments, nor do larger particles get selectively and consistently entrapped in steady vortices. Strikingly, a change in the shape of large particles from circular to elliptical resulted in stronger entrapments of smaller circular particles, but enhanced outflows of larger particles, which could be an alternative microfluidics-based method for sorting and separation of particles of different sizes and shapes.

description: We calculate the decoherence time of the ground state wave function of a nucleus in a high energy heavy ion collision. We define this time as the decay time of the ratio Tr D^2 / (Tr D)^2 of traces of the density matrix D. We find that this time is smaller or equal to 1/Q_s, where the saturation scale Q_s is defined within the color glass condensate model of parton saturation. Our result supports the notion that the extremely rapid entropy production deduced for the early stage of heavy ion collisions at collider energies is to a large extent caused by the decoherence of the initial-state wave functions.

description: An analysis of risk attitudes for a sample of grain sorghum producers in the Texas Coastal Bend is reported. Four alternative functional forms were estimated on data elicited by the direct elicitation of utility approach. The exponential functional form described most producers' utility preferences better than other utility forms. Relationships between exponential risk measures and both producer attributes and farm characteristics, including interactions among them, were identified as significant. Risk aversion was found to diminish with more experience in farming and to increase with more leasing of farm land. Risk aversion was also found to decline with larger farm size and to increase with higher dependency of farm operators on farm income.

description: Florida is typical of many southeastern states in that it exports feeder cattle and imports carcass and boxed beef. The objective of this paper is to estimate the cost of retaining feeder cattle in Florida, feeding these cattle to slaughter weights, slaughtering them, and distributing the meat to retail outlets. A mixed integer programming model is developed. The optimal number and location of feedlots and slaughter plants are determined. The results indicate that at production levels exceeding 600,000 head, the cost of producing carcass beef in the State is comparable to the average for the United States.

description: We study fractional 2p-branes and their intersection numbers in non-compact orbifolds as well the continuation of these objects in Kahler moduli space to coherent sheaves in the corresponding smooth non-compact Calabi-Yau manifolds. We show that the restriction of these objects to compact Calabi-Yau hypersurfaces gives the new fractional branes in LG orbifolds constructed by Ashok et. al. in hep-th/0401135. We thus demonstrate the equivalence of the B-type branes corresponding to linear boundary conditions in LG orbifolds, originally constructed in hep-th/9907131, to a subset of those constructed in LG orbifolds using boundary fermions and matrix factorization of the world-sheet superpotential. The relationship between the coherent sheaves corresponding to the fractional two-branes leads to a generalization of the McKay correspondence that we call the quantum McKay correspondence due to a close parallel with the construction of branes on non-supersymmetric orbifolds. We also provide evidence that the boundary states associated to these branes in a conformal field theory description corresponds to a sub-class of the boundary states associated to the permutation branes in the Gepner model associated with the LG orbifold.

description: I review the profound connection between the see-saw mechanism for neutrino masses and grand unification. This connection points naturally towards SO(10) grand unified theory. The emphasis here is on the supersymmetric theory, but I also discuss salient features of its split supersymmetry version and ordinary non-supersymmetric SO(10). Particular attention is paid to the crucial issue of the minimal such theory, i.e. the question of the Higgs sector needed to break SO(10) down to the Minimal Supersymmetric Standard Model or the Standard Model. Some essential features of the see-saw mechanism are clarified, in particular its precise origin at the high scale.

Installation and load testing of helical piles in a sensitive fine-grained soil
Creators: name: Weech, Christopher Nathan
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this research was to determine how soil disturbance caused by the installation of helical piles in sensitive fine-grained soils affects the mobilization of axial pile capacity at different times after installation. Six instrumented, full-scale helical piles were installed in lightly overconsolidated, highly sensitive, marine silt and clay at the Colebrook test site in South Surrey, B.C. Prior to pile installation, a detailed in-situ testing program was carried out using field vane shear tests and seismic piezocone penetration testing which included pore pressure dissipation tests. The excess pore pressures within the soil surrounding the piles was monitored during and after pile installation by means of piezometers located at various depths and radial distances from the pile shaft, and using piezo-ports which were mounted on the pile shaft. The changes in pore pressure during pile installation were indicators of the soil deformations caused by pile installation. The observed pore pressure dissipation around the piles indicated that primary reconsolidation of the soil was complete after about 7 days. After allowing a recovery period following installation, which varied between 19 hours, 7 days and 6 weeks, piles with two different helix plate spacings were loaded to failure under axial compressive loads. Strain gauges mounted on the pile shaft were monitored during load testing to determine the distribution of loading throughout the pile at the various load levels up to and including failure. Load-settlement curves were generated for different pile sections at different times after installation. The piezometers and piezo-ports were also monitored during load testing and the distribution of excess pore pressures was used as an indicator of the distribution of soil deformations caused by pile displacement. The undrained shear strengths mobilized by the different sections of the piles were backcalculated from the measured loads using published formulations. An "index of soil destructuring" is proposed which relates the ratio of the mobilized undrained shear strength to the in-situ vertical effective stress at the start of load testing to the corresponding strength ratios of the soil in its intact state and in a completely destructured state. The index of soil destructuring is proposed as the basis for a proposed capacity prediction method that is based on the undrained strength ratio.

description: We present a pilot study of 16 micron imaging within the GOODS northern field. Observations were obtained using the PeakUp imaging capability of the Spitzer IRS. We survey 35 square arcminutes to an average 3 sigma depth of 0.075 mJy and detect 149 sources. The survey partially overlaps the area imaged at 15 microns by ISO, and we demonstrate that our photometry and galaxy-number counts are consistent with their measurements. We infer the total infrared luminosity of 16 micron detections using a comparison to local templates and find a wide range of L_IR} from ~10^9 to 10^{12} L_sun. Approximately one fifth of the detected sources have counterparts in the Chandra 2 Msec catalog, and we show that the hard band (2-8 keV) detected sources are likely to have strong AGN contributions to the X-ray flux. The ultradeep sensitivity of Chandra implies some X-ray detections may be purely starbursting objects. We examine the 16 to 24 micron flux ratio and conclude that it shows evidence for the detection of redshifted PAH emission at z~0.5 and z>0.8.

The Discovery of a Hidden Broad Line AGN in a Bulgeless Galaxy: Keck NIR Spectroscopic Observations of SDSS J085153.64+392611.76

description: We report the discovery of a buried, active supermassive black hole in SDSS J085153.64+392611.76, a bulgeless Seyfert 2 (Sy2) galaxy. Keck near-infrared observations reveal a hidden broad line region, allowing for the rare case where strong constraints can be placed on both the black hole mass and bulge component. Using virial mass estimators, we obtain a black hole mass of log($M_{\rm{BH}}/M_{\odot}$) = $6.78 \pm 0.50$. This is one of the only Sy2 AGN hosted in a bulgeless galaxy with a virial black hole mass estimate and could provide important constraints on the formation scenarios of the black hole seed population. The lack of a bulge component suggests that the SMBH has grown quiescently, likely caused by secular processes independent of major mergers. In the absence of a detectable bulge component, we find the $M_{\rm{BH}}$ - $M_{\rm{stellar}}$ relation to be more reliable than the $M_{\rm{BH}}$ - $M_{\rm{bulge}}$ relation. In addition, we detect extended narrow Pa$α$ emission that allows us to create a rotation curve where we see counter-rotating gas within the central kiloparsec (kpc). Possible causes of this counter-rotation include a galactic bar or disruption of the inner gas by a recent fly-by of a companion galaxy. This in turn could have triggered accretion onto the central SMBH in the current AGN phase.

description: It has been previously demonstrated that women who utilize the competitorderogation strategy (which requires fierce and explicit tactics to secure resources)are perceived more negatively than those who utilize the self-promoting strategy(which includes subtler tactics to secure resources). Some of these resources aredirectly related to and for the benefit of a woman’s offspring. However, it remainsunknown how women who use these strategies for accessing resources for theiroffspring are perceived by potential rivals (other females) and potential mates(males). We propose that mothers who derogate their competition (other mothers)will be seen more negatively than those who self-promote. Using a pre-post studydesign, female participants rated 12 mothers’ photographs for attractiveness,competency as a mother, and personality. In the pre-condition participants rated thewoman in the photograph, while in the post-condition the participants rated her afterbeing told the woman made a ‘Facebook post’ containing maternal competitorderogation or self-promotion. Differences in pre-post ratings were calculated, withchange presumably caused by strategy use. Results indicate women who promotetheir maternal competency via self-promotion are perceived to be less likeablecompared to baseline ratings, and women who derogate their competition areperceived less positively on the majority of attributes.
