description: The unremitting image of Asian Americans as being "Model Minority" has created a veil that conceals their incessant struggles with discrimination, prejudice and microaggressions on individual, institutional and cultural levels.  Previous studies have highlighted the personal and collective struggles of this group and emphasized the harmful consequences to physical, emotional and mental well-being of Asian Americans. The current study explored potential factors that may influence the impact of experiencing racial microaggressions for Asian Americans.  More specifically, a 2 x 2 between-subjects factorial design was utilized to examine whether level of familiarity and role of power in the target's relationship with the perpetrator differentially impacts the experience of a racial microaggression.  A vignette illustrated a microaggressive encounter with a perpetrator who differed on these conditions with a sample of 263 Asian Americans.  The findings indicate support for the damaging psychological consequences of receiving racial microaggressions with participants reporting significantly negative experience when the perpetrator was someone familiar in a position of authority.  The results of the present study contribute to the literature on racial microaggressions by providing support for the injurious impact it has for Asian Americans and continues to challenge the model minority myth that persists to silence their voices and invalidate their racial reality.

description: Academic self-concept (ASC) is comprised of individual perceptions of one’s own academic ability. In a cross-sectional quasi-representative sample of 3,779 German elementary school children in grades 1 to 4, we investigated (a) the structure of ASC, (b) ASC profile formation, an aspect of differentiation that is reflected in lower correlations between domain-specific ASCs with increasing grade level, (c) the impact of (internal) dimensional comparisons of one’s own ability in different school subjects for profile formation of ASC, and (d) the role played by differences in school grades between subjects for these dimensional comparisons. The nested Marsh/Shavelson model, with general ASC at the apex and math, writing, and reading ASC as specific factors nested under general ASC fitted the data at all grade levels. A first-order factor model with math, writing, reading, and general ASCs as correlated factors provided a good fit, too. ASC profile formation became apparent during the first two to three years of school. Dimensional comparisons across subjects contributed to ASC profile formation. School grades enhanced these comparisons, especially when achievement profiles were uneven. In part, findings depended on the assumed structural model of ASCs. Implications for further research are discussed with special regard to factors influencing and moderating dimensional comparisons.
Differential Structure and Function of Primary Groups in Age Homogeneous versus Age Heterogeneous Areas for the Elderly
Creators: Siegel, David
Publisher: name: Columbia University
Year: 1982
Subjects: subject: Social service
subject: Aging
subject: Demography
subject: FOS: Sociology

description: Much of the relevant literature has indicated that age homogeneity of the neighborhood is beneficial for the elderly in increasing life satisfaction and morale, in fostering contacts with friends and neighbors, and in creating a high level of social activity.

However, the dependent variables used in these studies may create distortions in comparing age homogeneous and age heterogeneous neighborhoods. Life satisfaction and morale may be too global as dependent variables and based on too many factors in a person's environment to compare the effects of different neighborhood structures. Contacts with neighbors and friends may not be meaningful in all areas requiring primary group supports.

Therefore, in this study of 1423 elderly people in New York and Florida, Litwak's "Theory of Shared Functions" is used to suggest the application of another type of dependent variable (performance of primary group functions) to compare age homogeneous and age heterogeneous areas. The effect of homogeneity would depend on the degree the structure of primary groups available matches the requirements for the function to be performed.

Age homogeneity, while increasing the concentration of proximate age peers, may create distance from kin who have the most long term commitment. Therefore, one type of function (participation in leisure), which is based on common or age-related interests, is shown to be strongly facilitated by age homogeneity. Another (watching one's place), which benefits from proximity of neighbors, but not from a loss of speed of reaction by the elderly, is weakly facilitated. Another (help in long illness), which is based on long term commitment, is affected little by age homogeneity. With moderate long term commitment required, neighbors and friends are able to substitute for kin.

However, when larger degrees of long term commitment are required, for help with money matters, or help in long illness for those who are disabled, very old, or have low income, there is a significant decrease in the level of primary group aid between age heterogeneous and age homogeneous areas. This is particularly so for the elderly who are handicapped or who have multiple resource deficiencies, and are most affected by lack of kin.

The effects of homogeneity are found to be largely independent of state of residence.

description: This thesis presents the results of a spectroelectrochemical investigation into the interactions of two flotation collectors (mercaptobenzothiazole (MBT) and dithiophosphate (DTP)) with gold electrode and nanorods surfaces. The relevant compounds and ligands of these two collectors were characterised and identified by Raman spectroscopy and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). Gold nanorods (Au NRs) with average aspect ratio of 4.04 ± 0.08 were synthesised and reacted with MBT and DTP. Gold particle flotation was investigated using controlled potential techniques. Electrochemical techniques have also been used to investigate the open circuit potential (OCP) and controlled potential oxidation of chalcopyrite. The interaction of collectors with gold electrode surfaces was investigated using in situ surface-enhanced Raman scattering (SERS) spectroscopy. The SERS surface for a gold electrode was generated by electrochemically roughening using an oxidation-reduction cycling (ORC).

description: The formal education of musicians in popular music production requires students to engage with learning to use music technology. This can present a challenge to beginners, who can struggle to engage with the technical processes involved in operating these technologies. Navigating the complexities of a wide range of software and hardware can be a significant challenge. The development of effective strategies for supporting their learning activities requires consideration, because of the volume of information required for successful outcomes. The delivery of on-demand information through improved access to mobile technologies is a subject of interest in post-secondary education. This learning approach aligns with the learning strategies of users of technologies outside of formal education, where seeking technical tutorials is increasingly more common. Often musicians combine learning opportunities with popular music production activities, because of the wide range of skills and technologies involved in the area. Supporting students with a range of on-demand resources could assist students to develop skills in popular music production. This research project investigates the design principles that could be used to deliver these resources to maximise student engagement in on-demand learning. The study is conducted using a design-based-research methodology with students and staff within a conservatorium teaching popular music. The cohort of 125 students was invited to participate in the research through surveys and focus groups, while eight staff members contributed to the research through interviews. This evolved a series of design principles, which could be used as a guide for developing on-demand resources to support education in the area.

description: The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic processing has been difficult to interpret. For an understanding of complex sensory processing, detailed concepts of the corticothalamic interplay need yet to be established. To study corticogeniculate processing in a model, we draw on various physiological and anatomical data concerning the intrinsic dynamics of geniculate relay neurons, the cortical influence on relay modes, lagged and nonlagged neurons, and the structure of visual cortical receptive fields. In extensive computer simulations we elaborate the novel hypothesis that the visual cortex controls via feedback the temporal response properties of geniculate relay cells in a way that alters the tuning of cortical cells for speed.

Cancer in women

description: Breast cancer is fast becoming the leading cause of mortality in women worldwide. As of this year, there are more than 3.1 million women with a history of breast cancer in the U.S., and about 41,760 women are expected to die from this disease. Neoadjuvant chemotherapy (NAC) has become a well-established therapy in the treatment of patients with locally advanced or primarily inoperable breast cancer. It consists of 3-9 months of drug treatment to shrink the tumor size before surgical removal of any remaining mass. A pathological complete response (pCR) is defined as complete disappearance of the tumor before surgery and correlates with 5-year overall survival of the treated patient. However, only 15-40% of subjects who undergo NAC will achieve a pCR, while the remaining patients do not benefit from a therapy that has considerable side effects. In this Ph.D. thesis, I explore the potential of diffuse optical tomography (DOT) for breast cancer imaging and NAC monitoring. The overall objective is two-fold. First, I seek to identify breast cancer patients who will not respond to NAC shortly after the initiation of a 5-9 months therapy regimen. Identifying these patients early will allow a switch to a more promising therapy and avoiding months of ineffective therapy with a drug regimen that has considerable side effects. Second, I use the optical data simultaneously obtained from the contralateral, non-tumor bearing breast to better understand the factors that modulate breast density and the source of its contrast in DOT. This work analyzed DOT data from 105 patients with stage II-III breast cancer under NAC regimen. Data processing and image analysis protocols were developed to more effectively evaluate static tissue contrast and dynamic functional imaging of the breast. Notably, we observed that there are differences in the time evolution of DOT features between pCR and non-pCR tumors under NAC, and DOT features can contribute to the successful prediction of pCR status from pretreatment imaging. Lastly, our analysis demonstrated a positive correlation between DOT feature and mammographic density classification, which could lead to research on the potential use of DOT as a predictor of breast cancer as well as an assessment tool to longitudinally evaluate the efficacy of chemoprevention strategies. These findings represent important steps towards the translation of DOT into current clinical workflow to contribute to better-personalized breast cancer therapies and breast cancer risk management.

description: Simulations of neutron star-black hole (NSBH) binaries generally consider black holes with masses in the range $(5-10)M_\odot$, where we expect to find most stellar mass black holes. The existence of lower mass black holes, however, cannot be theoretically ruled out. Low-mass black holes in binary systems with a neutron star companion could mimic neutron star-neutron (NSNS) binaries, as they power similar gravitational wave (GW) and electromagnetic (EM) signals. To understand the differences and similarities between NSNS mergers and low-mass NSBH mergers, numerical simulations are required. Here, we perform a set of simulations of low-mass NSBH mergers, including systems compatible with GW170817. Our simulations use a composition and temperature dependent equation of state (DD2) and approximate neutrino transport, but no magnetic fields. We find that low-mass NSBH mergers produce remnant disks significantly less massive than previously expected, and consistent with the post-merger outflow mass inferred from GW170817 for moderately asymmetric mass ratio. The dynamical ejecta produced by systems compatible with GW170817 is negligible except if the mass ratio and black hole spin are at the edge of the allowed parameter space. That dynamical ejecta is cold, neutron-rich, and surprisingly slow for ejecta produced during the tidal disruption of a neutron star : $v\sim (0.1-0.15)c$. We also find that the final mass of the remnant black hole is consistent with existing analytical predictions, while the final spin of that black hole is noticeably larger than expected -- up to $χ_{\rm BH}=0.84$ for our equal mass case.

description: Peripheral arterial disease (PAD) affects approximately 200 million individuals worldwide. It is characterized by a reduction in blood flow to the lower extremities due to atherosclerosis. This can result in leg pain, tissue loss, and ultimately amputation. Revascularization procedures aim to restore blood flow, but up to 50% of patients require another intervention within a year. Revascularization monitoring and early detection of failure are crucial in preventing limb loss and adverse cardiovascular events. However, current evaluation methods do not directly measure perfusion and are limited in a significant segment of PAD patients, such as those with diabetes and renal insufficiency. Diffuse optical imaging (DOI) techniques are promising tools to overcome these limitations. Employing near-infrared light, they are non-invasive, non-ionizing, contrast-free, and cost-effective methods that are sensitive to hemodynamic parameters such as changes in oxy-, deoxy-, and total hemoglobin concentration, making DOI ideal for revascularization monitoring.
      In this dissertation, I investigate and develop DOI systems for the purpose of monitoring lower extremity revascularization procedures in PAD patients. We utilize a contact-based diffuse optical spectroscopy (DOS) system to monitor localized foot perfusion in an ongoing clinical study of 100 patients undergoing lower extremity angiography. I demonstrate the utility of DOS measurements to provide valuable insights into revascularization related hemodynamic remodeling and to predict revascularization success. Furthermore, I also develop a clinic friendly contact-free diffuse optical tomography (DOT) system that is better-suited for PAD patients with ulcers. I show that this system can provide spatial maps of perfusion within the foot. Collectively, this work establishes diffuse optical imaging as a valuable imaging modality for the evaluation of lower extremity perfusion.

description: This dissertation redefines Los Angeles “light and space” art, tracing the multiple strains of abstract light art that developed in California during the postwar technology boom. These artists used new technical materials and industrial processes to expand modernist definitions of medium and create perceptual experiences based on their shared understanding of light as artistic material. The diversity and experimental nature of early Light and Space practice has been suppressed within the discourse of “minimal abstraction,” a term I use to signal the expansion of my analysis beyond the boundaries of work that is traditionally associated with “minimalism” as a movement. My project focuses on three women: Mary Corse, Helen Pashgian and Maria Nordman, each of whom represents a different trajectory of postwar light-based practice in California. While all of these artists express ambivalence about attempts to align their practice with the Light and Space movement, their work provides fundamental insight into the development of light art and minimal abstract practice in California during this era. In chapter one, I map the evolution of Mary Corse’s experimental “light painting” between 1964 and 1971, in which the artist experimented with new technology—including fluorescent bulbs and the reflective glass microspheres used in freeway lane dividers—to expand the perceptual boundaries of monochrome painting by manifesting an experience of pure white light. In chapter two, I plot the development of Helen Pashgian’s plastic resin sculpture from her early pieces cast in handmade molds to her disc sculptures that mobilized the expertise of the faculty and aeronautical engineering technology available to her during an artist residency at the California Institute of Technology between 1969 and 1971. In chapter three, I chart the origins of Maria Nordman’s ephemeral post-studio practice using natural light from her early works that modified the architecture of her Los Angeles studio, to installations in which she excised sections of the walls or ceilings of commercial spaces and galleries, and finally to her project at the University Art Museum at the University of California, Berkeley for the 1979 Space as Support series, in which she turned the museum building into a container for the light of the summer solstice. The reception history I construct outlines how gender bias suppressed the contributions of women within the critical and historical discourse surrounding light-based work and minimal abstraction, while also exploring how women mobilized Light and Space’s interest in embodied perceptual experience as part of my wider analysis of the tactics deployed by women making abstract work before the discursive spaces of feminism and institutional critique were fully formed.
Diffusion related processes in nanoconfined liquids and in proteins under force

description: This thesis investigates some diffusion related problems, in acetonitrile confined in silica nanopores, and in modeling single molecule forced rupture experiments of biomacromolecules. Based on a method used to calculate the position-dependent diffusion coefficients in inhomogeneous liquids, we apply absorbing boundary conditions in the analysis of molecular dynamics trajectories of confined acetonitrile. We show that the dynamics of acetonitrile may be described by a two population exchange model that accounts for bulk-like relaxation in the center, frustrated dynamics near the surface of the pore and the self-diffusion. We find that hydrogen-bonding interactions play a large role in engendering this behavior. We compare our method with prior techniques that do not take diffusion into account and discuss their pitfalls. We also calculate the position-dependent diffusion tensors in the center population of acetonitrile. To model single molecule forced rupture experiments under constant velocity conditions, we study the barrier crossing problem of a diffusive particle in a time-dependent potential, We develop an integral equation connecting the first passage time distribution of a Brownian diffusion process in the presence of an absorbing boundary condition and the corresponding Green's function in the absence of the absorbing boundary. We further investigate the numerical solutions of the integral equation for a diffusion process in a time-dependent potential. Our numerical procedure, based on the exact integral equation, avoids the adiabatic approximation used in the previous analytical theories and is useful for fitting the rupture force distribution data from experiments, especially at larger pulling speeds, large cantilever spring constants, and smaller reaction rates. We also propose a model based on subdiffusion to explain the anomalous rupture force distributions with positive skewness that are observed in some single molecule forced rupture experiments of ligand-receptor complexes.

description: Since their inception in the 30's by von Neumann, operator algebras have been used in shedding light in many mathematical theories. Classification results for self-adjoint and non-self-adjoint operator algebras manifest this approach, but a clear connection between the two was sought since their emergence in the late 60's. We connect these seemingly separate type of results by uncovering a hierarchy of classification for non-self-adjoint operator algebras and $C^*$-algebras with additional $C^*$-algebraic structure. Our approach naturally applies to algebras arising from $C^*$-correspondences to resolve self-adjoint and non-self-adjoint isomorphism problems in the literature. We apply our strategy to completely elucidate this newly found hierarchy for operator algebras arising from directed graphs.

description: Atmospheric temperatures are increasing and precipitation ranges are generally believed to become more variable and more extreme, with a general reduction in rainfall expected across South-eastern Australia. Additionally, increases in evapotranspiration are expected, resulting in an expected prevailing net loss in the terrestrial water balance. Changes in climate are bringing increasing uncertainty to ecological systems, where the predicted changes to climate are likely to have impacts on amphibians due to the close ecological associations of amphibians to temperature and environmental water balances. Amphibians largely have a dependency upon free-standing water to enable recruitment, which for many species is dependent upon the occurrence of seasonally ephemeral, low predator ponds. While climate change is recognised to affect species along gradients, many gradients occur at smaller spatial scales than that of latitudinal and altitudinal gradients.

Architecture--Preservation

description: Digital photogrammetry has established itself as an effective tool for documenting cultural heritage in the twenty-first century. With portable equipment and a relatively short amount of time, an incredible amount of surface data can be captured for an object and stored as point clouds. This richness of data raises questions of whether it should be used for analytical purposes in addition to documentation.

 This thesis researches using close-range, digital photogrammetry to describe physical change over time. The image sets were captured, point clouds created in Agisoft, and analyzed using CloudCompare to identify any dislocations.

 Three-dimensional changes that are not easily measured or observed were chosen as the focus of this research and they were broken into three typologies: cracking, erosion, and warping. Each was recreated using a proxy experiment and gave different degrees of analytical data for The degree to which these changes can be detected will drive what sort of analytical conclusions can be drawn.

 This comparative photogrammetry can identify areas of change that may be easily ignored by the humane eye due to their slow, gradual rate of change. When these two points in time are compared directly in the form of two high resolution point clouds, minute changes become discreet and take shape. Once the shape becomes a pattern, material condition could begin to be speculated.

 With two well executed data sets, it is possible to detect and visualize the changes between two experimental models. The challenge lies in understanding how CloudCompare understands these changes and then translating that language into analytical decisions about the condition of the material. The speed, ease, and relatively low cost of photogrammetry makes it very effective at homing in on areas of concern.

description: In this paper we develop a phenomenological model inspired by QCD that mimics QCD theory. We use gauge theory in color dielectric medium ($G(ϕ)$) coupled with fermion fields to produce scalar and vector confinement in chromoelectric flux tube scenario. Abelian theory will be used to approximate the non-Abelian QCD theory in a consistent manner. We will calculate vector and scalar glueballs and compare the result to the existing simulation and experimental results and projections. The QCD-like vacuum associated with the model will be calculated and its behavior studied relative to changing quark masses. We will also comment on the relationship between tachyon condensation, dual Higgs mechanism, QCD monopole condensation and their association with confinement. The behavior of the QCD string tension obtained from the vector potential of the model will be studied to establish vector dominance in confinement theories.

description: We discuss the nature and physical properties of gas-mass selected galaxies in the ALMA spectroscopic survey (ASPECS) of the Hubble Ultra Deep Field (HUDF). We capitalize on the deep optical integral-field spectroscopy from the MUSE HUDF Survey and multi-wavelength data to uniquely associate all 16 line-emitters, detected in the ALMA data without preselection, with rotational transitions of carbon monoxide (CO). We identify ten as CO(2-1) at $1 < z < 2$, five as CO(3-2) at $2 < z < 3$ and one as CO(4-3) at $z = 3.6$. Using the MUSE data as a prior, we identify two additional CO(2-1)-emitters, increasing the total sample size to 18. We infer metallicities consistent with (super-)solar for the CO-detected galaxies at $z \le 1.5$, motivating our choice of a Galactic conversion factor between CO luminosity and molecular gas mass for these galaxies. Using deep Chandra imaging of the HUDF, we determine an X-ray AGN fraction of 20% and 60% among the CO-emitters at $z \sim 1.4$ and $z \sim 2.6$, respectively. Being a CO-flux limited survey, ASPECS-LP detects molecular gas in galaxies on, above and below the main sequence (MS) at $z \sim 1.4$. For stellar masses $\ge 10^{10} (10^{10.5})$ M$_{\odot}$, we detect about 40% (50%) of all galaxies in the HUDF at $1 < z < 2$ ($2 < z < 3$). The combination of ALMA and MUSE integral-field spectroscopy thus enables an unprecedented view on MS galaxies during the peak of galaxy formation.

description: A profile from the Argo ocean observation array is a sequence of three-dimensional vectors composed of pressure, salinity, and temperature, appearing as a continuous curve in three-dimensional space. The shape of this curve is faithfully represented by a path signature, which is a collection of all the iterated integrals. Moreover, the product of two terms of the signature of a path can be expressed as the sum of higher-order terms. Thanks to this algebraic property, a nonlinear function of profile shape can always be represented by a weighted linear combination of the iterated integrals, which enables machine learning of a complicated function of the profile shape. In this study, we performed supervised learning for existing Argo data with quality control flags by using the signature method, and demonstrated the estimation performance by cross-validation. Unlike rule-based approaches, which require several complicated and possibly subjective rules, this method is simple and objective in nature because it relies only on past knowledge regarding the shape of profiles. This technique should be critical to realizing automatic quality control for Argo profile data.

description: Classical strings propagating in $AdS_{3}\times S^{3}\times T^{4}$ supported with Neveu-Schwarz-Neveu-Schwarz flux are described by a Wess-Zumino-Witten model. In this note, we study the emergence of their semiclassical $SU(2)$ spectrally flowed sectors as the Landau-Lifshitz limit of the underlying quantum spin chain. We consider the propagator in the coherent state picture, and find that the time interval is discretized proportionally to the lattice spacing. In the Landau-Lifshitz limit, where both time and space become continuous, we derive a path integral representation of the propagator for each spectrally flowed sector. We prove that the arbitrariness of the global phase of coherent states is mapped to the gauge freedom of the $B$-field in the classical action. We show that higher order corrections in the Landau-Lifshitz limit are suppressed by inverse powers of the 't Hooft coupling.

Educational technology

description: The aspects of educational institutions and the systemic practice of education are the product of 2 distinct features of education. The first is the institutional practice of a chosen philosophy of education. The second is the technologies that have afforded the facilitation of information production, consumption and distribution essential processes of education. Taking advantage of major reform opportunities in educational practice, made possible by an emerging digital information system the current trend in education tends to relinquish the long tradition of philosophy of education and embraces the cultivation of a reflective and productive citizenry through education. However, by looking at the ways in which the technologies of their time constrained or enabled the imaginations of our most influential philosophers of education (Plato, Rousseau and Dewey), we will better understand how real technologies and ideal philosophies are necessarily related. With such knowledge, we may inform our educational reform alternatives with the goal of developing a democratic citizenry through education. In no way, is this dissertation meant to provide specific recommendations for educational reform though the Digital Dante case study illustrates some possible reform alternatives. Rather, it is meant to demonstrate the ways in which technology and philosophy, educational institutions and industry and K-12 and higher education are all necessary players in the goal of creating a new form of civic education.
