Teaching The Process Of Molecular Phylogeny And Systematics: A Multi-Part Inquiry-Based Exercise, Nathan H. Lents, Oscar E. Cifuentes, Anthony Carpi

Publications and Research

Three approaches to molecular phylogenetics are demonstrated to biology students as they explore molecular data from Homo sapiens and four related primates. By analyzing DNA sequences, protein sequences, and chromosomal maps, students are repeatedly challenged to develop hypotheses regarding the ancestry of the five species. Although these exercises were designed to supplement and enhance classroom instruction on phylogeny, cladistics, and systematics in the context of a postsecondary majors-level introductory biology course, the activities themselves require very little prior student exposure to these topics. Thus, they are well suited for students in a wide range of educational levels, including a biology …

Survivalism And Public Opinion On Criminality: A Cross-National Analysis Of Prostitution, Steven Stack, Amy Adamczyk, Liqun Cao

Publications and Research

Explanations of variability in public opinion on crime have drawn disproportionately from the literature on specific symbolic orientations including religious fundamentalism and racial prejudice. In contrast, this article hypothesizes that public opinion is linked to the strength of a general cultural axis of nations: survivalism vs. self-expressionism. Data are from the fourth wave of the World Values Survey. Hierarchical modeling techniques are used to sort out the bi-level effects of survivalist culture on the approval of prostitution. Controlling for all other predictors, the personal survivalism index was the most powerful predictor of prostitution acceptability, followed by the country-level survivalism index. …

The Mds Mortality Risk Index: The Evolution Of A Method For Predicting 6-Month Mortality In Nursing Home Residents, Davina Porock, Debra Parker-Oliver, Gregory F. Petroski, Marilyn Rantz

Publications and Research

Background: Accurate prognosis is vital to the initiation of advance care planning particularly in a vulnerable, at risk population such as care home residents. The aim of this paper is to report on the revision and simplification of the MDS Mortality Rating Index (MMRI) for use in clinical practice to predict the probability of death in six months for care home residents.

Methods: The design was a secondary analysis of a US Minimum Data Set (MDS) for long term care residents using regression analysis to identify predictors of mortality within six months.

Results: Using twelve easy to collect …

Gloria E. Anzaldúa’S Decolonizing Ritual De Conocimiento, Sarah S. Ohmer

Publications and Research

Gloria E. Anzaldúa’s work makes up one of the many Chican@ works that contribute another history, a history repressed by the national discourses on both sides of the border. Influenced by antecedents of U.S. Hispanic Literature who superposed “official” history with another history, Chicano activists had already enacted a retrieval of pre-conquest histories to revive their people’s historical consciousness. As Saldívar-Hull states in “Mestiza Consciousness and Politics: Gloria Anzaldúa’s Borderlands/ La frontera,” the publication of Borderlands/ La Frontera distinguished itself from the Chicano movement’s as it unveiled the curtain that hid the Aztec goddesses and kept aspects of pre-conquest history …

Rotational Doppler Effect In Magnetic Resonance, S Ledinez, Eugene M. Chudnovsky, Javier Tejada

Publications and Research

We compute the shift in the frequency of the spin resonance in a solid that rotates in the field of a circularly polarized electromagnetic wave. Electron spin resonance, nuclear magnetic resonance, and ferromagnetic resonance are considered. We show that contrary to the case of the rotating LC circuit, the shift in the frequency of the spin resonance has strong dependence on the symmetry of the receiver. The shift due to rotation occurs only when rotational symmetry is broken by the anisotropy of the gyromagnetic tensor, by the shape of the body, or by magnetocrystalline anisotropy. General expressions for the resonance …

Dipolar Ordering In Crystals Of Mn12 Ac, Dmitry A. Garanin

Publications and Research

Ordering in realistic elongated box-shape crystals of the molecular magnet Mn_12 Ac is investigated with the site-resolved mean-field approximation that does not assume a uniform ordering. It is shown that ferromagnetic ordering should not occur in crystals with the aspect ratio up to 12. Instead, for the aspect ratio about 6, the inner and outer regions of the crystal order in different directions, uniformly along its length. Finding ordering temperature by extrapolating the inverse susceptibility curve does not provide a correct T_C.

Edges And Diffractive Effects In Casimir Energies, Daniel N. Kabat, Dimitra Karabali, V P. Nair

Publications and Research

The prototypical Casimir effect arises when a scalar field is confined between parallel Dirichlet boundaries. We study corrections to this when the boundaries themselves have apertures and edges. We consider several geometries: a single plate with a slit in it, perpendicular plates separated by a gap, and two parallel plates, one of which has a long slit of large width, related to the case of one plate being semi-infinite. We develop a general formalism for studying such problems, based on the wavefunctional for the field in the gap between the plates. This formalism leads to a lower dimensional theory defined …

On The Casimir Interaction Between Holes In A Plate, Daniel N. Kabat, Dimitra Karabali, V P. Nair

Publications and Research

We study the leading long-distance attractive force between two holes in a plate arising from a scalar eld with Dirichlet boundary conditions on the plate. We use a formalism in which the interaction is governed by a non-local eld theory which lives on the two holes. The interaction energy is proportional to Q1Q2=r7 at large separation r, where Q1 and Q2 are certain charges associated with the holes. We compute these charges for round and rectangular holes. We show that the 1=r7 behavior is universal for separations large compared to the linear dimensions of the holes, irrespective of the spin …

Dynamical Decompactification And Three Large Dimensions, Brian Greene, Daniel N. Kabat, Stefanos Marnerides

Publications and Research

We study string gas dynamics in the early universe and seek to realize the Brandenberger - Vafa mechanism - a goal that has eluded earlier works - that singles out three or fewer spatial dimensions as the number which grow large cosmologically. Considering wound string interactions in an impact parameter picture, we show that a strong exponential suppression in the interaction rates for d > 3 spatial dimensions reflects the classical argument that string worldsheets generically intersect in at most four spacetime dimensions. This description is appropriate in the early universe if wound strings are heavy - wrapping long cycles - …

The Hamiltonian Approach To Yang-Mills (2 + 1): Expansion Scheme And Corrections To String Tension, Dimitra Karabali, V P. Nair, Alexandr Yelinkov

Publications and Research

We carry out further analysis of the Hamiltonian approach to Yang-Mills theory in 2+1 dimensions which helps to place the calculation of the vacuum wave function and the string tension in the context of a systematic expansion scheme. The solution of the Schrodinger equation is carried out recursively. The computation of correlators is re-expressed in terms of a two-dimensional chiral boson theory. The effective action for this theory is calculated to first order in our expansion scheme and to the fourth order in a kinematic expansion parameter. The resulting corrections to the string tension are shown to be very small, …

Nearest Neighbor Search With Strong Location Privacy, Stavros Papadopoulos, Spiridon Bakiras, Dimitris Papadias

Publications and Research

The tremendous growth of the Internet has significantly reduced the cost of obtaining and sharing information about individuals, raising many concerns about user privacy. Spatial queries pose an additional threat to privacy because the location of a query may be sufficient to reveal sensitive information about the querier. In this paper we focus on k nearest neighbor (kNN) queries and define the notion of strong location privacy, which renders a query indistinguishable from any location in the data space. We argue that previous work fails to support this property for arbitrary kNN search. Towards this end, we introduce methods that …

Modern Time: Photography And Temporality, Kris Belden-Adams

Dissertations, Theses, and Capstone Projects

This dissertation explores the fluid relationship of photography to time. Many theorists have noted that photography has a distinctive manner of representing temporality. Roland Barthes, for example, wrote that the photograph has a peculiar capacity to represent the past in the present, and thus to imply the passing of time in general. As a consequence, Barthes argued, all photographs speak of the inevitability of our own death in the future. Moreover, he linked photography's peculiar temporality to its capacity for a certain kind of realism: "false on the level of perception, true on the level of time." Barthes's analysis poses …

The Interaction Of Intensity And Deviance On Auditory Event-Related Potentials: Findings Using Principal Component Analysis (Pca) Of Current Source Densities (Csds), Nathan A. Gates

Dissertations, Theses, and Capstone Projects

Mismatch negativity (MMN) studies provide insights into the brain's ability to perceive and/or detect deviations from established sensory patterns. Clinical studies investigating the loudness-dependency of auditory evoked potential (LDAEP) have shown a relationship between the intensity of an auditory stimulus and neuro-physiological or -chemical activity of the primary auditory cortex. Unfortunately, these two bodies of literature remain disjointed. The present study integrates elements of each body of literature to a) investigate the impact of varying levels of intensity deviance on N1/P2 with a standard set of intensities used in LDAEP paradigms, and b) assess the extent to which deviance-related processes …

Madness, Sexuality, And Gender In Early Twentieth Century Music Theater Works: Four Interpretive Essays, Megan B. Jenkins

Dissertations, Theses, and Capstone Projects

Diagnoses of madness are inextricably entwined with social and cultural beliefs about gender and sexual behavior. The portrayal of characters in music theater as mad relies on contemporaneous understanding of mental illness, as often resulting from, or expressed in transgression of normative gender roles or heteronormativity, and this may apply either to male or female characters. Such transgressions are explored--with regard to recent reconceptualizations of madness within Disability Studies--in four works: Arnold Schoenberg's monodrama Erwartung (1924); Richard Strauss's opera Salome (1905); Kurt Weill's ballet chanté, Anna-Anna (1933), also known as The Seven Deadly Sins; and Igor Stravinsky's neo-classical …

“We Went To The Hills": Four Afghan Life Stories, James M. Weir

Dissertations, Theses, and Capstone Projects

This dissertation examines four Afghan life stories for prevalent micro-historical perspectives on shared Afghan macro-historical experiences. The introduction explains my background, motivations and objectives for conducting life history research in Afghanistan in 2004 and 2005. The first chapter outlines an approach applied to examining life stories that addresses three interrelated questions: first, how the narrator's presentation is related to the memory of the actual events narrated (biographical chronology), second, how a narrative image/s of a person's past is established in relationships to individually significant audience/s (narrative self / audience), and third, how interrelationships between the individual …

Colombian Artists In Paris, 1865-1905, Maya Jiménez

Dissertations, Theses, and Capstone Projects

This dissertation brings together a group of artists not previously studied collectively, within the broader context of both Colombian and Latin American artists in Paris. Taking into account their conditions of travel, as well as the precarious political and economic situation of Colombia at the turn of the twentieth century, this investigation exposes the ways in which government, politics and religion influenced the stylistic and thematic choices made by these artists abroad. For those who were pensioned artists and who were restricted by a defined political agenda, their artistic experimentation was limited, while the more radical artists were typically wealthy …

Moderator Effects Of Working Memory On Symptom Stability In Attention-Deficit/Hyperactivity Disorder By Dopamine D1 And D2 Receptor Polymorphisms During Development, Joey W. Trampush

Dissertations, Theses, and Capstone Projects

Background: Developmental changes in dopaminergic pathways in the prefrontal cortex (PFC) that are important for working memory have been hypothesized to play a central role in the trajectory of attention-deficit/hyperactivity disorder (ADHD), but not the initial onset of the disorder. This dissertation research examines whether dopamine receptor D1 (DRD1) and dopamine receptor D2 (DRD2) gene polymorphisms moderate the association between improvements in working memory and declines in attention problems in ADHD from childhood to adolescence/young adulthood. Methods: Participants were 76 racially/ethnically diverse youth diagnosed with ADHD in childhood and followed prospectively for almost 10 years. Stability of ADHD symptomatology …

Teaching Style: An Investigation Of New York City Public High School Teacher Dress Practices, Anne J. Brownstein

Dissertations, Theses, and Capstone Projects

In recent decades there has been increasing interest in regulating teacher appearance in the schools. While there is a great deal of anecdotal data available about what dress standards for teachers should be, to the best of the researcher's knowledge no one has undertaken scholarly research to investigate teacher attitudes towards their constructions of self, self-as-teacher, and educational philosophies as expressed by dress practices.

Predicated upon the theory that the study of self presentation provides a window through which we can gain insight into these constructions, this dissertation investigates how a sample of nine New York City public high school …

Discrimination Of Tone Contrasts In Mandarin Disyllables By Naïve American English Listeners, Shari Salzhauer Berkowitz

Dissertations, Theses, and Capstone Projects

The present study examined the perception of Mandarin disyllabic tones by inexperienced American English speakers. Participants heard two naturally-produced Mandarin disyllables, and indicated if the two were the same or different. A small native Mandarin-speaking control group participated as well. All 21 possible Mandarin contrasts where the initial syllable varied but the final syllable stayed the same were tested. Acoustic analysis was performed on the stimuli under study. Mandarin subjects scored at ceiling on all contrasts. American English subjects performed poorly on contrasts where the difference in mean F0 was small, or where the difference in the offset F0 of …

The Effect Of Teaching Attending To A Face On Joint Attention Skills In Children With An Autism Spectrum Disorder, Tina Rovito Gomez

Dissertations, Theses, and Capstone Projects

Autism spectrum disorders are characterized in terms of behavioral deficits in areas of social behavior and language development. A failure to attend to the faces of others is the single best discriminator between 1-year-old children later diagnosed with an autism spectrum disorder (ASD) and those with typical development. Attending to the face of another provides the opportunity for episodes of attention sharing and is important to the development of communication, joint attention, and social behavior. A more advanced form of attending to a face is joint attention which has been defined as the ability to coordinate attention between an object …

Children's Tolerance Of Word-Form Variation, Paul Reeves Breuning

Dissertations, Theses, and Capstone Projects

This study compared children's (N=96, mean age 4;1, range 2;8-5;3) and adults' (N=96, mean age 21 years) tolerance of word-onset modifications (e.g., wabbit and warabbit) and pseudo affixes (e.g., kocat and catko) in a label extension task. Trials comprised an introductory phase where children saw a picture of an animal and were told its name, and a test phase where they were shown the same picture along with one of a different animal. For `similar-name' trials, participants heard a word-form modification of the previously introduced name (e.g., introduced to a dib, they were asked, `which animal is a wib?'). For …

Qualitative And Quantitative X-Ray Diffraction Analysis For Forensic Examination Of Duct Tapes, Rebecca E. Bucht

Dissertations, Theses, and Capstone Projects

Duct tapes are an increasingly important class of forensic evidence. This research has studied the value of using x-ray diffraction (XRD) to extend the ability of evidence examiners to gain additional information about a duct tape specimen.

Duct tapes are composed of five different layers. Starting from the non-adhesive side, these layers are the release coating, backing, scrim, primer and adhesive. The release coating assists in reducing unwind tension and preventing the tape from sticking to itself when on a roll. The backing layer serves as a support for the adhesive, and is usually based on polyethylene. The scrim is …

Essays On Economic Policy: Income Inequality And Health Insurance, Eric Doviak

Dissertations, Theses, and Capstone Projects

This dissertation contains economic analyses of two critical social issues facing the United States at the dawn of the 21st century: income inequality and the affordability of health insurance.

The chapter on income inequality uses the Solow Model of economic growth to model the evolution of inequality over time. In steady state, differences in household saving rates generate differences in household capital income. Households that save more accumulate more capital and have higher steady-state income. Tax policy affects the distribution of income through its influence on household saving rates. Increasing the tax rate on labor income causes a greater percentage …
