Connecting Numbers To Discrete Quantification: A Step In The Child’S Construction Of Integer Concepts, Emily Slusser, A. Ditta, B. Sarnecka Oct 2013

Connecting Numbers To Discrete Quantification: A Step In The Child’S Construction Of Integer Concepts, Emily Slusser, A. Ditta, B. Sarnecka

Emily Slusser

The present study asks when young children understand that number words quantify over sets of discrete individuals. For this study, 2- to 4-year-old children were asked to extend the number word five or six either to a cup containing discrete objects (e.g., blocks) or to a cup containing a continuous substance (e.g., water). In Experiment 1, only children who knew the exact meanings of the words one, two and three extended higher number words (five or six) to sets of discrete objects. In Experiment 2, children who only knew the exact meaning of one extended higher number words to discrete …


Finite-Temperature Properties Of Strongly Correlated Fermions In The Honeycomb Lattice, Baoming Tang, Thereza Paiva, Ehsan Khatami, Marchos Rigol Sep 2013

Finite-Temperature Properties Of Strongly Correlated Fermions In The Honeycomb Lattice, Baoming Tang, Thereza Paiva, Ehsan Khatami, Marchos Rigol

Ehsan Khatami

We study finite-temperature properties of strongly interacting fermions in the honeycomb lattice using numerical linked-cluster expansions and determinantal quantum Monte Carlo simulations. We analyze a number of thermodynamic quantities, including the entropy, the specific heat, uniform and staggered spin susceptibilities, short-range spin correlations, and the double occupancy at and away from half filling. We examine the viability of adiabatic cooling by increasing the interaction strength for homogeneous as well as for trapped systems. For the homogeneous case, this process is found to be more efficient at finite doping than at half filling. That, in turn, leads to an efficient adiabatic …

Laurie A. Drabble

University-community partnerships are increasingly recognized as valuable in educating students for professional practice and bridging the gap between research and practice. This manuscript describes the evolution and design of a university-community partnership between a School of Social Work in one urban university and local child welfare agencies: the Child Welfare Partnership for Research and Training (CW-PART). This local partnership illustrates types of opportunities and outcomes that emerge when state and local entities leverage greater results from federal funding through partnerships with local universities. The manuscript describes 1), the community-engaged framework used to inform the overall approach and partner roles; 2) …


Alcohol In The Life Narratives Of Women: Commonalities And Differences By Sexual Orientation, Laurie A. Drabble, K. Trocki Jul 2013

Alcohol In The Life Narratives Of Women: Commonalities And Differences By Sexual Orientation, Laurie A. Drabble, K. Trocki

Laurie A. Drabble

Aim: The aim of this study was to explore social representations of alcohol use among women, with a focus on possible differences between sexual minority and heterosexual women. Methods: This qualitative study was part of a larger study examining mediators of heavier drinking among sexual minority women (lesbian identified, bisexual identified, and heterosexual identified with same sex partners) compared to heterosexual women based on the National Alcohol Survey. Qualitative in-depth life history interviews were conducted over the telephone with 48 women who had participated in the 2009–2010 National Alcohol Survey, including respondents representing different sexual orientation groups. Questions explored the …


Lines In The Sand: Social Representations Of Substance Use Boundaries In Life Narratives, K. F. Trocki, L. O. Michalak, Laurie A. Drabble Apr 2013

Lines In The Sand: Social Representations Of Substance Use Boundaries In Life Narratives, K. F. Trocki, L. O. Michalak, Laurie A. Drabble

Laurie A. Drabble

This study identifies social representations in interviews about alcohol and substance use in the discourse of 129 young adults, who were interviewed for 2.5 to 3.5 hr each for their life histories and use or nonuse of alcoholic beverages and drugs. Respondents spontaneously delineated their substance use boundaries, creating a continuum of behaviors with boundary points separating acceptable from unacceptable behaviors. They used signaling expressions to indicate go and stop signs and movement along the substance use continuum and reported negotiating substance use boundaries both internally and with peers. A ubiquitous narrative element was the cautionary tale, in which a …


Effects Of Ad-Valorem Taxes On Location Decision Under Free Entry Cournot Oligopoly, Yeung-Nan Shieh Mar 2013

Effects Of Ad-Valorem Taxes On Location Decision Under Free Entry Cournot Oligopoly, Yeung-Nan Shieh

Yeung-Nan Shieh

This paper examines the impact of the ad-valorem commodity tax as a policy device on the location decision of undifferentiated oligopolistic firms with free entry. It shows that: (1) When the distance between the plant location and the output market is held constant, the optimum location for the oligopolistic firm would be independent of the ad-valorem tax if the production function is homothetic, and (2) when the distance between the plant location and the output market is a decision variable, the optimum location for the oligopolistic firm will move closer to the output market if the demand function is linear …


Sexual Orientation Differences In The Relationship Between Victimization And Hazardous Drinking Among Women In The National Alcohol Survey, Laurie A. Drabble, K. F.. Trocki, T. L. Hughes, R. A. Korcha, A. E.. Lown Feb 2013

Sexual Orientation Differences In The Relationship Between Victimization And Hazardous Drinking Among Women In The National Alcohol Survey, Laurie A. Drabble, K. F.. Trocki, T. L. Hughes, R. A. Korcha, A. E.. Lown

Laurie A. Drabble

This study examined relationships between past experiences of victimization (sexual abuse and physical abuse in childhood, sexual abuse and physical abuse in adulthood, and lifetime victimization) and hazardous drinking among sexual minority women compared to exclusively heterosexual women. Data were from 11,169 women responding to sexual identity and sexual behavior questions from three National Alcohol Survey waves: 2000 (n = 3,880), 2005 (n = 3,464), and 2010 (n = 3,825). A hazardous drinking index was constructed from five dichotomous variables (5+ drinking in the past year, drinking two or more drinks daily, drinking to intoxication in the past year, two …

Impact Of Older Adults’ Experience With Psychotherapy On Treatment Engagement, Erin L. Woodhead, I. I. Ivan, E. E. Emery Jan 2013

Impact Of Older Adults’ Experience With Psychotherapy On Treatment Engagement, Erin L. Woodhead, I. I. Ivan, E. E. Emery

Erin L. Woodhead

The goal of the study was to characterize older adults' experience with psychotherapy and examine its impact on engagement in psychotherapy. The study included 50 adults over age 60 who screened positive for depression and participated in the BRIGHTEN Program, an interdisciplinary geriatric mental health program. Qualitative analyses revealed five themes leading to treatment initiation: health concerns, family issues, the experience of depressive symptoms, beliefs about what participants could get from psychotherapy, and positive outcomes seen in others. Those without a history of mental health treatment were more likely to endorse health concerns as a treatment motivator and were more …


Brief Communication: Evolution Of A Specific O Allele (O1vg542a) Supports Unique Ancestry Of Native Americans, Fernando A. Villanea, Deborah A. Bolnick, Cara Monroe, Rosita Worl, Rosemary Cambra, Alan M. Leventhal, Brian M. Kemp Jan 2013

Brief Communication: Evolution Of A Specific O Allele (O1vg542a) Supports Unique Ancestry Of Native Americans, Fernando A. Villanea, Deborah A. Bolnick, Cara Monroe, Rosita Worl, Rosemary Cambra, Alan M. Leventhal, Brian M. Kemp

Alan M. Leventhal

In this study, we explore the geographic and temporal distribution of a unique variant of the O blood group allele called O1vG542A, which has been shown to be shared among Native Americans but is rare in other populations. O1vG542A was previously reported in Native American populations in Mesoamerica and South America, and has been proposed as an ancestry informative marker. We investigated whether this allele is also found in the Tlingit and Haida, two contemporary indigenous populations from Alaska, and a pre-Columbian population from California. If O1vG542A is present in Na-Dene speakers (i.e., Tlingits), it would indicate that Na-Dene speaking …

The Role Of Canids In Ritual And Domestic Contexts: New Ancient Dna Insights From Complex Hunter-Gatherer Sites In Prehistoric Central California, Alan M. Leventhal, Brian F. Byrd, Anna Cornellas, Jelmer W. Eerkens, Jeffrey Rosenthal, Tim R. Carpenter, Jennifer A. Leonard Jan 2013

The Role Of Canids In Ritual And Domestic Contexts: New Ancient Dna Insights From Complex Hunter-Gatherer Sites In Prehistoric Central California, Alan M. Leventhal, Brian F. Byrd, Anna Cornellas, Jelmer W. Eerkens, Jeffrey Rosenthal, Tim R. Carpenter, Jennifer A. Leonard

Alan M. Leventhal

This study explores the interrelationship between the genus Canis and hunter–gatherers through a case study of prehistoric Native Americans in the San Francisco Bay-Sacramento Delta area. A distinctive aspect of the region's prehistoric record is the interment of canids, variously classified as coyotes, dogs, and wolves. Since these species are difficult to distinguish based solely on morphology, ancient DNA analysis was employed to distinguish species. The DNA study results, the first on canids from archaeological sites in California, are entirely represented by domesticated dogs (including both interments and disarticulated samples from midden deposits). These results, buttressed by stable isotope analyses, …


Situating The Customer: The Genealogy Of Customer Language In Libraries, Susan Maret, Ben Eagle Jan 2013

Situating The Customer: The Genealogy Of Customer Language In Libraries, Susan Maret, Ben Eagle

Susan Maret

By way of Michel Foucault’s genealogical method, in this article we hope to advance discussion within Library and Information Science (LIS) of customer language and “customer-driven librarianship,” or those themes and practices “that both responds to and reinforces an economic vision of librarianship at its base, culminating in the ‘customer’ concept” (Buschman, 2003, p. 110).


Planetary Nebula Spectrograph Survey Of S0 Galaxy Kinematics – Ii. Clues To The Origins Of S0 Galaxies, A. Cortesi, M. R. Merrifield, L. Coccato, M. Arnaboldi, O. Gerhard, Aaron J. Romanowsky, N. G. Douglass, K. Kuiijken, M. Capaccioli, K. C. Freeman, K. Saha, A. L. Chies-Santos Jan 2013

Planetary Nebula Spectrograph Survey Of S0 Galaxy Kinematics – Ii. Clues To The Origins Of S0 Galaxies, A. Cortesi, M. R. Merrifield, L. Coccato, M. Arnaboldi, O. Gerhard, Aaron J. Romanowsky, N. G. Douglass, K. Kuiijken, M. Capaccioli, K. C. Freeman, K. Saha, A. L. Chies-Santos

Aaron J. Romanowsky

The stellar kinematics of the spheroids and discs of S0 galaxies contain clues to their formation histories. Unfortunately, it is difficult to disentangle the two components and to recover their stellar kinematics in the faint outer parts of the galaxies using conventional absorption line spectroscopy. This paper therefore presents the stellar kinematics of six S0 galaxies derived from observations of planetary nebulae, obtained using the Planetary Nebula Spectrograph. To separate the kinematics of the two components, we use a maximum-likelihood method that combines the discrete kinematic data with a photometric component decomposition. The results of this analysis reveal that: the …

Aaron J. Romanowsky

The origins of S0 galaxies remain obscure, with various mechanisms proposed for their formation, likely depending on environment. These mechanisms would imprint different signatures in the galaxies' stellar kinematics out to large radii, offering a method for distinguishing between them. We aim to study a sample of six S0 galaxies from a range of environments, and use planetary nebulae (PNe) as tracers of their stellar populations out to very large radii, to determine their kinematics in order to understand their origins. Using a special-purpose instrument, the Planetary Nebula Spectrograph, we observe and extract PNe catalogues for these six systems*. We …


The Sluggs Survey: Wide Field Imaging Of The Globular Cluster System Of Ngc 4278, C. Usher, D. A. Forbes, L. R. Spitler, J. P. Brodie, Aaron J. Romanowsky, J. Strader, K. A. Woodley Jan 2013

The Sluggs Survey: Wide Field Imaging Of The Globular Cluster System Of Ngc 4278, C. Usher, D. A. Forbes, L. R. Spitler, J. P. Brodie, Aaron J. Romanowsky, J. Strader, K. A. Woodley

Aaron J. Romanowsky

We use multipointing Hubble Space Telescope Advanced Camera for Surveys and wide field Subaru Suprime-Cam imaging to study the globular cluster system of the L* elliptical galaxy NGC 4278. We have also obtained a handful of new globular cluster spectra with the Keck Deep Imaging Multi-Object Spectrograph. We determine the globular cluster surface density profile and use it to calculate the total number of globular clusters, finding the system to be slightly more populous than average for galaxies of its luminosity. We find clear evidence for bimodality in the globular cluster colour distribution and for a colour–magnitude relation in the …


Deer Herd Management Using The Internet: A Comparative Study Of California Targeted By Data Mining The Internet, G. Kent Webb Jan 2013

Deer Herd Management Using The Internet: A Comparative Study Of California Targeted By Data Mining The Internet, G. Kent Webb

G. Kent Webb

An ongoing project to investigate the use of the internet as an information source for decision support identified the decline of the California deer population as a significant issue. Using Google Alerts, an automated keyword search tool, text and numerical data were collected from a daily internet search and categorized by region and topic to allow for identification of information trends. This simple data mining approach determined that California is one of only four states that do not currently report total, finalized deer harvest (kill) data online and that it is the only state that has reduced the amount of …


Angular Momentum And Galaxy Formation Revisited: Effects Of Variable Mass-To-Light Ratios, S. M. Fall, Aaron J. Romanowsky Jan 2013

Angular Momentum And Galaxy Formation Revisited: Effects Of Variable Mass-To-Light Ratios, S. M. Fall, Aaron J. Romanowsky

Aaron J. Romanowsky

We rederive the relation between the specific angular momentum j sstarf and the mass M sstarf of the stellar matter in galaxies of different morphological types. This is a revision of the j sstarf-M sstarf diagram presented in our recent comprehensive study of galactic angular momentum. In that work, we estimated j sstarf from kinematic and photometric data that extended to large radii and M sstarf from near-infrared luminosities LK with an assumed universal mass-to-light ratio M sstarf/LK . However, recent stellar population models show large variations in M sstarf/LK correlated with B – V color. In the present work, …

Filling The Gap: A New Class Of Old Star Cluster?, D. A. Forbes, V. Pota, C. Usher, Aaron J. Romanowsky, J. Strader, J. P. Brodie, J. A. Arnold, L. R. Spitler

Aaron J. Romanowsky

It is not understood whether long-lived star clusters possess a continuous range of sizes and masses (and hence densities) or if rather, they should be considered as distinct types with different origins. Utilizing the Hubble Space Telescope to measure sizes and long exposures on the Keck 10 m telescope to obtain distances, we have discovered the first confirmed star clusters that lie within a previously claimed size–luminosity gap dubbed the ‘avoidance zone’ by Hwang et al. The existence of these star clusters extends the range of sizes, masses and densities for star clusters, and argues against current formation models that …


The Sluggs Survey: Outer Triaxiality In The Fast Rotator Elliptical Ngc 4473, C. Foster, J. A. Arnold, D. A. Forbes, N. Pastorello, Aaron J. Romanowsky, L. R. Spitler, J. Strader, J. P. Brodie Jan 2013

The Sluggs Survey: Outer Triaxiality In The Fast Rotator Elliptical Ngc 4473, C. Foster, J. A. Arnold, D. A. Forbes, N. Pastorello, Aaron J. Romanowsky, L. R. Spitler, J. Strader, J. P. Brodie

Aaron J. Romanowsky

Systematic surveys of nearby early-type galaxies using integral field unit (IFU) spectrograph data have revealed that galaxies can hide interesting structures only visible through kinematic studies. As part of their pioneering work, the ATLAS3D team have shown that most morphologically elliptical galaxies are centrally kinematically disc like. Hence, while global morphology suggests that ellipticals are ellipsoidal/triaxial in shape, their central kinematics may be consistent with (inclined) oblate systems. Here, we study the fast rotator elliptical galaxy: NGC 4473. Using slitlets, we obtain galaxy light kinematics out to unprecedentedly large galactocentric radii (2.5 effective radii). While we confirm the IFU results …


The Sluggs Survey: Probing The Supermassive Blackhole Connection With Bulges And Haloes Using Red And Blue Globular Cluster Systems, V. Pota, A. W. Graham, D. A. Forbes, Aaron J. Romanowsky, A. J. Brodie, J. Strader Jan 2013

The Sluggs Survey: Probing The Supermassive Blackhole Connection With Bulges And Haloes Using Red And Blue Globular Cluster Systems, V. Pota, A. W. Graham, D. A. Forbes, Aaron J. Romanowsky, A. J. Brodie, J. Strader

Aaron J. Romanowsky

Understanding whether the bulge or the halo provides the primary link to the growth of supermassive black holes has strong implications for galaxy evolution and supermassive black hole formation itself. In this paper, we approach this issue by investigating extragalactic globular cluster (GC) systems, which can be used to probe the physics of both the bulge and the halo of the host galaxy. We study the relation between the supermassive black hole masses (MBH) and the GC system velocity dispersions (σGC) using an updated and improved sample of 21 galaxies. We exploit the dichotomy of GC system colours, to test …


An Inventory Of The Stellar Initial Mass Function In Early-Type Galaxies, C. Tortora, Aaron J. Romanowsky, N. R. Napolitano Jan 2013

An Inventory Of The Stellar Initial Mass Function In Early-Type Galaxies, C. Tortora, Aaron J. Romanowsky, N. R. Napolitano

Aaron J. Romanowsky

Given a flurry of recent claims for systematic variations in the stellar initial mass function (IMF), we carry out the first inventory of the observational evidence using different approaches. This includes literature results, as well as our own new findings from combined stellar population synthesis (SPS) and Jeans dynamical analyses of data on ~4500 early-type galaxies (ETGs) from the SPIDER project. We focus on the mass-to-light ratio mismatch relative to the Milky Way IMF, δIMF, correlated against the central stellar velocity dispersion, σsstarf. We find a strong correlation between δIMF and σsstarf, for a wide set of dark matter (DM) …


The Paucity Of Globular Clusters Around The Field Elliptical Ngc 7507, J. P. Caso, T. Richtler, L. P. Bassino, R. Salinas, R. R. Lane, Aaron J. Romanowsky Jan 2013

The Paucity Of Globular Clusters Around The Field Elliptical Ngc 7507, J. P. Caso, T. Richtler, L. P. Bassino, R. Salinas, R. R. Lane, Aaron J. Romanowsky

Aaron J. Romanowsky

There is strong evidence that globular cluster systems (GCSs) of massive galaxies are largely assembled by infall/accretion processes. Therefore, we expect the GCSs of isolated elliptical galaxies to be poor. Alhough not completely isolated, NGC 7507 is a massive field elliptical galaxy with an apparently very low dark matter content. Aims: We determine the richness, the colour distribution, and the structural properties of the GCS of NGC 7507. Methods: We perform wide-field Washington photometry with data obtained with the MOSAIC II camera at the 4m-Blanco telescope, CTIO. Results: The GCS is very poor with S_N ~ 0.6. We identify three …

Aaron J. Romanowsky

We report the discovery of a remarkable ultra-compact dwarf galaxy around the massive Virgo elliptical galaxy NGC 4649 (M60), which we call M60-UCD1. With a dynamical mass of 2.0 × 108 M ☉ but a half-light radius of only ~24 pc, M60-UCD1 is more massive than any ultra-compact dwarfs of comparable size, and is arguably the densest galaxy known in the local universe. It has a two-component structure well fit by a sum of Sérsic functions, with an elliptical, compact (rh = 14 pc; n ~ 3.3) inner component and a round, exponential, extended (rh = 49 pc) outer component. …
