An ethnographic account of economic constraints and ethical issues: Terminal illness in three institutional settings
Creators: name: Mottur-Pilson, Christel
Publisher: name: American University
Year: 2023

description: American society and medicine are experiencing severe strains and tensions in their attitudes toward and management of adult terminal illness. Several factors contribute to this crisis of confidence and judgment: (1) The number of our older citizens is steadily increasing. (2) Sophisticated medical technology can sustain biological life beyond previously imagined limits. (3) The very success of medicine has ushered in an era of ambivalence. (4) The boundaries of life and death are no longer clearly defined but open to interpretation. (5) The right to adequate medical care is challenged by concerns over cost containment and the appropriate allocation of health care resources. This research is a qualitative analysis of clinical cases in three institutions: hospital, hospice, and nursing home. The focus is on the decision-making process surrounding adult terminal care. The ethnographer is the main research instrument. Since the research addresses the interplay of bioethics and economic constraints, reflexive ethnography is used to highlight how public policy affects individuals and institutions. In effect, this is an account of the struggles of individuals as they attempt to make sense out of existing ambiguities. Within their particular economic constraints, each institution tailors the dying process so that it accords with its own health care goals and functions. For example, the hospital, an acute care institution, defines and manages terminal illness differently from a hospice. The hospice, an institution designed to address the needs of the dying, avoids any "heroic efforts" to prolong life unduly. The nursing home, a long-term care institution, concentrates primarily on health care maintenance measures designed to prevent flare-ups of chronic conditions or drastic deterioration. Yet each institution has to deal with dying patients. Terminal care requires not only medical expertise but compassion and ethical concern for the patients. Specifically then, bioethics can help health professionals mediate the tensions among institutional goals, economic constraints, technological influences, and patient and family preferences. The extent to which this is true is the focus of this dissertation. Concluding, this dissertation presents proposals on how to cope with some of the problematical areas in all three institutions.

description: We investigate theoretically the emergence of classical statistical physics in a finite quantum system that is either totally isolated or otherwise subjected to a quantum measurement process. We show via a random matrix theory approach to nonintegrable quantum systems that the set of outcomes of the measurement of a macroscopic observable evolve in time like stochastic variables, whose variance satisfies the celebrated Einstein relation for Brownian diffusion. Our results show how to extend the framework of eigenstate thermalization to the prediction of properties of quantum measurements on an otherwise closed quantum system. We show numerically the validity of the random matrix approach in quantum chain models.

description: This dissertation examines feminist claims about the relationship between women and peace and men and war against the backdrop of women's roles in organizing for peace and participating in wars in a historical, contemporary, and international context. It argues, through an analysis of feminist theory, peace research, and praxis, that we must move beyond both androcentric and gynocentric constructions of reality, which are both products of patriarchal ideologies and relations that give rise to the dualistic, polemical, and intransigent politics of war and peace. The first three chapters make the case that past and contemporary feminist attempts to idealize women's roles in the private or reproductive realm as a basis for a unified feminist politics, which counters men's "armed civic virtue" with women's "feminine civic virtue," are problematic with respect to the struggles for women's liberation and peace. The next two chapters offer a case study of women's international peace conference held in Halifax, Canada just prior to the final UN Decade for Women events in Nairobi, Kenya in 1985. In exploring the Halifax conference process, which involved over 1,000 women from thirty-three countries, it is found that women do not have homogeneous views on peace and security. In fact, it is shown that women's political identities and priorities in the struggle for peace vary with class, race, culture, and nationality, giving rise to varying, and, sometimes, conflicting "practical" and "strategic" gender interests. However, the conference process did reveal that all women suffer to some degree from the social, economic, and political priorities of patriarchy, capitalism, imperialism, and militarism which depend upon women's undervalued and unremunerated reproductive labor under increasingly oppressive and repressive conditions. The final chapter calls for a feminist political process that enlarges the scope of political change and embraces women's multiple identities, feminisms, and struggles for peace. Such a process opens up the possibility for women to forge more liberatory solidarities with other women and with men to break through the polemics, in discourse and praxis, of women and peace and men and war.
Assessing the effects of foregrounds and sky removal in WMAP

subject: FOS: Physical sciences

description: Many recent analyses have indicated that large scale WMAP data display anomalies that appear inconsistent with the standard cosmological paradigm. However, the effects of foreground contamination, which require elimination of some fraction of the data, have not been carefully investigated due to the complexity in the analysis. Here we develop a general formalism of how to incorporate these effects in any analysis of this type. Our approach is to compute the full multi-dimensional probability distribution function of all possible sky realizations that are consistent with the data and with the allowed level of contamination. As an example we apply this method to compute the joint probability distribution function for the possible realizations of quadrupole and octopole using the WMAP data. This 12 dimensional distribution function is explored using the Markov Chain Monte Carlo technique. The resulting chains are used to asses the statistical significance of the low quadrupole using frequentist methods, the quadrupole-octopole alignment using several methods (angular momentum dispersion, multipole vectors and a new method based of feature matching) and the quadrupole-octopole aligment with ecliptic.

description: We present the proton and neutron vector form factors in a convenient parametric form that is optimized for momentum transfers $\lesssim$ few GeV$^2$. The form factors are determined from a global fit to electron scattering data and precise charge radius measurements. A new treatment of radiative corrections is applied. This parametric representation of the form factors, uncertainties and correlations provides an efficient means to evaluate many derived observables. We consider two classes of illustrative examples: neutrino-nucleon scattering cross sections at GeV energies for neutrino oscillation experiments and nucleon structure corrections for atomic spectroscopy. The neutrino-nucleon charged current quasielastic (CCQE) cross section differs by 3-5% compared to commonly used form factor models when the vector form factors are constrained by recent high-statistics electron-proton scattering data from the A1 Collaboration. Nucleon structure parameter determinations include: the magnetic and Zemach radii of the proton and neutron, $[r_M^p, r_M^n] = [ 0.739(41)(23), 0.776(53)(28)]$ fm and $[r_Z^p, r_Z^n] = [ 1.0227(94)(51), -0.0445(14)(3)]$ fm; the Friar radius of nucleons, $[(r^p_F)^3, (r^n_F)^3] = [2.246(58)(2), 0.0093(6)(1)]$ fm$^3$; the electric curvatures, $[\langle r^4 \rangle^p_E, \langle r^4 \rangle^n_E ] = [1.08(28)(5), -0.33(24)(3)]$ fm$^4$; and bounds on the magnetic curvatures, $[ \langle r^4 \rangle^p_M, \langle r^4 \rangle^n_M ] = [ -2.0(1.7)(0.8), -2.3(2.1)(1.1)]$ fm$^4$. The first and dominant uncertainty is propagated from the experimental data and radiative corrections, and the second error is due to the fitting procedure.

description: Rural people no longer rely primarily on agriculture for their livelihood. The number of agricultural counties receiving at least 20 percent of their total labor and proprietors’ income from farming declined from 2,016 in 1950 to 684 in the midseventies. This report documents the decline in counties dependent on agriculture and identifies counties where farming still provides a large portion of income and employment. Counties still depending on agriculture have unique farm and economic characteristics. This report also examines the structure of agriculture in its changing local environment.

description: This work describes through semiclassical Boltzmann transport theory and simulation a novel nanostructured material design that can lead to unprecedentedly high thermoelectric power factors, with improvements of more than an order of magnitude compared to optimal bulk material power factors. The design is based on a specific grain/grain-boundary (potential well/barrier) engineering such that: i) carrier energy filtering is achieved using potential barriers, combined with ii) higher than usual doping operating conditions such that high carrier velocities and mean-free-paths are utilized, iii) minimal carrier energy relaxation after passing over the barriers to propagate the high Seebeck coefficient of the barriers into the potential wells, and importantly, iv) the formation of an intermediate dopant-free (depleted) region. The design consists thus of a three-region geometry, in which the high doping resides in the center/core of the potential well, with a dopant-depleted region separating the doped region from the potential barriers. It is shown that the filtering barriers are optimal when they mitigate the reduction in conductivity they introduce, and this can be done primarily when they are clean from dopants during the process of filtering. The potential wells, on the other hand, are optimal when they mitigate the reduced Seebeck they introduce by: i) not allowing carrier energy relaxation, and importantly ii) by mitigating the reduction in mobility that the high concentration of dopant impurities cause. Dopant segregation, with clean dopant-depletion regions around the potential barriers, serves this key purpose of improved mobility towards the phonon-limited mobility levels in the wells. Using quantum transport simulations as well as semi-classical Monte Carlo simulations we also verify the important ingredients and validate this clean-filtering design.

Socio-economic adaptation and ethnicity evolution of the Chinese in the Washington, D.C. area: A contextualist perspective
Creators: name: Chen, Mau-Thai
Publisher: name: American University
Year: 2023

description: Human societies in the modern world, with the rare exception of some homogeneous societies, are plagued with internal multiethnic tensions and conflicts, the political aspects every society has to cope with effectively. A multicultural society turns out to be a mosaic in reality, due to the reasons that cultural pluralism does not facilitate cultural integration but leads to hierarchical social segments characterized by different access to political, economic, and jural resources. Probably out of reaction to the failure of multiculturism, current American society has been galloping away from its ideal of melting-pot and toward a "purification" campaign. Far from intending to engage in a herculean effort to counteract the trend of this campaign, this study aims at providing a piece of solid research relevant to the issue concerning the validity and reliability of this campaign. With this aim, this study combines historical scope and anthropological depth to investigate five contextualizations of ethnicity, which emerge from the Toisanese-Chinese's creation of adaptive actions throughout the historical time of their presence in the Metropolitan Washington area. The impacts from larger American society, Toisanese culture, and social situations were produced and reproduced to entail the unique contextualization of societal formation, social personality, ethnic enclave development, dramatization of social role performance and community framing process among the Toisanese-Chinese. As noted, these five contextualizations show that actors in different levels hold different ethnic consciousness, reflecting their different adaptations to the life contexts they are exposed to. This study, by marshalling a multitude of sources of data, offers an apparently unlikely connection among microcosm, macrocosm, synchronicity, and diachronicity to those who study culture for the sake of culture. All these five contextualizations, epitomized by the interplay between the microcosm and the macrocosm in the multidimensional processes, have led straight into one of the most important aspects concerning ethnicity change; that is, ethnicity evolution is understandable only by linking microanalysis with macrothemes. All in all, this study confirms the applicability of the emerging culture model and the impact-integration model as evidenced by the fact that Toisanese-Chinese ethnicity has acquired a shifting profile and characteristics that set it apart from those previous ones.

description: Adaptive optics (AO) is critical in astronomy, optical communications and remote sensing to deal with the rapid blurring caused by the Earth's turbulent atmosphere. But current AO systems are limited by their wavefront sensors, which need to be in an optical plane non-common to the science image and are insensitive to certain wavefront-error modes. Here we present a wavefront sensor based on a photonic lantern fibre-mode-converter and deep learning, which can be placed at the same focal plane as the science image, and is optimal for single-mode fibre injection. By measuring the intensities of an array of single-mode outputs, both phase and amplitude information on the incident wavefront can be reconstructed. We demonstrate the concept with simulations and an experimental realisation wherein Zernike wavefront errors are recovered from focal-plane measurements to a precision of $5.1\times10^{-3}\;π$ radians root-mean-squared-error.

description: Electro-production of pions and kaons at the kinematics of quasi-elastic knockout (which is well known in the physics of atomic nucleus and corresponds to the $t$-pole diagram) is proposed for obtaining their momentum distribution (MD) in various channels of virtual decay $N \to B+π$, $B=N$, $Δ$, $N^*$, $N^{**}$, and $N \to Y+K$, $Y=Λ$, $Σ$. It is a powerful tool for investigation of a quark microscopic picture of the meson cloud in the nucleon. A model of scalar $q \bar{q}$ ($^3P_0$) fluctuation in the non-trivial QCD vacuum is used to calculate pion and kaon momentum distributions (MD) in these channels.

In other words, they exist in any spacetime of the form R^{1,1} x M_8, with M_8 any of the usual reduced holonomy manifolds. These generalised supertubes preserve 1/4 of the supersymmetries preserved by the choice of the manifold M_8. We also support this picture with the construction of their corresponding family of IIA supergravity backgrounds preserving from 1/4 to 1/32 of the total supercharges.

description: The ground state of a hole-doped t-t'-J ladder with four legs favors a striped charge distribution. Spin excitation from the striped ground state is known to exhibit incommensurate spin excitation near q=(pi,pi) along the leg direction (qx direction). However, an outward dispersion from the incommensurate position toward q=(0,pi) is strong in intensity, inconsistent with inelastic neutron scattering (INS) experiment in hole-doped cuprates. Motivated by this inconsistency, we use the t-t'-J model with m x n=96 lattice sites by changing lattice geometry from four-leg (24x4) to rectangle (12x8) shape and investigate the dynamical spin structure factor by using the dynamical density matrix renormalization group. We find that the outward dispersion has weak spectral weights in the 12x8 lattice, accompanied with the decrease of excitation energy close to q=(pi,pi), being consistent with the INS data. In the 12x8 lattice, weakening of incommensurate spin correlation is realized even in the presence of the striped charge distribution. For further investigation of geometry related spin dynamics, we focus on direction dependent spin excitation reported by recent resonant inelastic x-ray scattering (RIXS) for cuprate superconductors and obtain a consistent result with RIXS by examining an 8x8 t-t'-J square lattice.

description: We present results from a spectroscopic study of ~4000 galaxies in a 6.2 square degree field in the direction of the Aquarius supercluster and a smaller typical field region in Cetus, down to R<19.5. Galaxy redshifts were measured using the Two Degree Field system on the Anglo-Australian Telescope, and form part of our wider efforts to conduct a spectro-photometric and weak gravitational lensing study of these regions. At the magnitude limit of the survey, we are capable of probing L_* galaxies out to z~0.4. We construct median spectra as a function of various survey parameters as a diagnostic of the quality of the sample. We use the redshift data to identify galaxy clusters and groups within the survey volume. In the Aquarius region, we find a total of 48 clusters and groups, of which 26 are previously unknown systems, and in Cetus we find 14 clusters and groups, of which 12 are new. We estimate centroid redshifts and velocity dispersions for all these systems. In the Aquarius region, we see a superposition of two strong superclusters at z=0.08 and z=0.11, which both have estimated masses and overdensities similar to the Corona Borealis supercluster.

description: The nearby ($\sim$500 kpc) metal-poor ([Fe/H] $\approx$ -1.2; $Z$ $\approx$ 30% $Z_{\odot}$) star-forming galaxy NGC 6822 has a metallicity similar to systems at the epoch of peak star formation. Through identification and study of dusty and dust-producing stars, it is therefore a useful laboratory to shed light on the dust life cycle in the early Universe. We present a catalog of sources combining near- and mid-IR photometry from the United Kingdom Infrared Telescope (UKIRT; $J$, $H$, and $K$) and the $Spitzer$ $Space$ $Telescope$ (IRAC 3.6, 4.5, 5.8, and 8.0 $μ$m and MIPS 24 $μ$m). This catalog is employed to identify dusty and evolved stars in NGC 6822 utilizing three color-magnitude diagrams (CMDs). With diagnostic CMDs covering a wavelength range spanning the near- and mid-IR, we develop color cuts using kernel density estimate (KDE) techniques to identify dust-producing evolved stars, including red supergiant (RSG) and thermally-pulsing asymptotic giant branch (TP-AGB) star candidates. In total, we report 1,292 RSG candidates, 1,050 oxygen-rich AGB star candidates, and 560 carbon-rich AGB star candidates with high confidence in NGC 6822. Our analysis of the AGB stars suggests a robust population inhabiting the central stellar bar of the galaxy, with a measured global stellar metallicity of [Fe/H] = -1.286 $\pm$ 0.095, consistent with previous studies. In addition, we identify 277 young stellar object (YSO) candidates. The detection of a large number of YSO candidates within a centrally-located, compact cluster reveals the existence of an embedded, high-mass star-formation region that has eluded previous detailed study. Spitzer I appears to be younger and more active than the other prominent star-forming regions in the galaxy.

To make a connection with ultrasonic experiments on ergodic elastodynamic billiards, the channels injecting and collecting the waves are assumed to be negligibly coupled to the medium, and to contribute essentially no dissipation. Within the RMT model we calculate the quantities of interest exactly, employing the supersymmetry technique. This approach is found to be more accurate than another method based on simplifying naive assumptions for the statistics of the eigenfrequencies and the eigenfunctions. The results of the supersymmetric method are confirmed by Monte Carlo numerical simulation and are used to reveal a possible source of the disagreement between the predictions of the naive theory and ultrasonic measurements.

The cultural dimension of external dependence: An inquiry into the internal cultural consequences of external dependence in Iran

Subjects: classificationCode: 44
subject: Human society

description: The purpose of this research is to investigate the cultural consequences of Iran's dependent relationship with the Western Capitalist countries. The "dependency" paradigm is used as the theoretical framework, and the historical analysis is applied to examine the general condition of Iran during the nineteenth and twentieth centuries and to find out what factors were responsible for Iran's dependency. The study argues that the commercial penetration of Iran by the European rival forces, beginning in the late sixteenth century, led to the early incorporation of the Iranian economy into the emerging world Capitalist system. The intensification of Colonial rivalry for the domination of the Iranian market by the late nineteenth century transformed the pre-Capitalist structure of Iran into a dependent Capitalism. According to the study, in addition to the penetration of foreign capital, the absolute arbitrary power of the Iranian kings was a major obstacle to the economic development of Iran. The study maintains that Western domination of the Iranian society also affected the Iranian culture through market structure. The early cultural penetration of Iran, beginning in the nineteenth century, was facilitated and accelerated during the period between 1925 to 1978 by Western-oriented policies of the Iranian regimes. This was due to the fact that the increased influence of foreign capital forced the Iranian ruling class to adopt certain directions and policies for social reforms to change the traditional structure of the society. These policies facilitated the cultural penetration of the country, through the massive importation of Western consumer goods and cultural products. Factors such as education, mass media communication, and printed publications played a crucial role in the course of Western cultural penetration into Iran. The result was cultural polarization of the country: a minority among the upper and upper-middle classes became westernized and alienated from the indigenous culture and the majority who rejected Western culture and opposed the regime's westernization policies. This study maintains that the lranian revolution of 1979, with religious characteristics, symbolized the response of the Iranian people to the Western domination, especially its cultural hegemony over the Iranian society.

An empirical model of technological change and industry-level investment
Creators: name: Cooper, Ronald Scott
Publisher: name: American University
Year: 2023

description: The role of technological change as a determinant of investment behavior has been either ignored or inadequately incorporated in the mainstream literature on investment dynamics, as well as in alternative traditions of economic thought. In this study, a recent empirical model of firm investment behavior in the United States is extended to include variables representing the effects of technological progress. The model that is extended lies within the post-Keynesian tradition in that it views investment as a function of capacity utilization and internally- and externally-generated finance. The principal empirical hypothesis tested is that U.S. industry and firm investment behavior during the 1980s was partly determined by the intensity of industry-level technological change. An additional hypothesis, that technological change influences investment by creating competitive pressures on firms to increase their investments in new productive capital, is also explored. A composite variable representing the intensity or pace of technological change is constructed, using factor analysis, and entered into a single-equation variance components regression model. The composite variable is based upon the rates of change in five proxy variables assumed to be correlates of the process of technological change. The model is estimated from pooled time series-cross section data at the firm segment and industry levels for the U.S. manufacturing sector from 1981 through 1986. The analysis shows the technological change variable (which is assumed to represent primarily product-related technological change) to be a significant determinant of investment behavior, especially in highly concentrated industries.
