description: The general goal of this dissertation is to shed some light on the involvement of developing countries in communications satellite activities. The specific aims are: (1) to investigate predominant factors that have made Indonesia the first developing country to acquire its own domestic communications satellite, PALAPA; (2) to discuss the decision making and implementations processes of both international and domestic communications satellite systems in Indonesia: and (3) to analyze the applications and the implications of this sophisticated technology in Indonesia. To put the analysis in its proper perspective, a review of the historical development, present global status, and the basic technological principles of the communications satellite is provided. And using contextual analysis, the political, economic, technological, and socio-cultural factors that appear to have influenced the implementation and applications of the technology are discussed. The study is founded on the base of a large and varied collection of resources, including reports, newspaper and magazine articles, Indonesian parliamentary hearings, personal interviews, archives materials, governmental and non-governmental documents and data which mostly heretofore had not been used in scholarly research. The study shows that the degree of involvement of developing countries in communications satellite activities is determined by three conditions: the availability and accessibility of the technology, the suitability of the technology with the country's particular needs and conditions, and the existence of supportive external and internal factors and actors. While the external economic factors and actors were found to be dominant in the applications of the communications satellite for international communications in Indonesia, the internal political factors and actors were found to be more determinant in its domestic communications. The research finds that the satellite PALAPA was established and has been used predominantly for national integration, revenue-earning point-to-point telecommunications, national television, and the armed forces network in Indonesia. The challenge now is to increase the utilization of this technology for community development--e.g., education, health, agricultural extension--to benefit the underprivileged segments of the society.

description: Recent theories predict dissipationless spin current induced by an electric field in doped semiconductors. Nevertheless, the charge current is still dissipative in these systems. In this work, we theoretically predict the dissipationless spin Hall effect, without any accompanying charge current, in some classes of band insulators, including zero-gap semiconductors such as HgTe and narrow-gap semiconductors such as PbTe. This effect is similar to the quantum Hall effect in that all the states below the gap contribute and there occurs no dissipation. However the spin Hall conductance is not quantized even in two dimensions. This is the first example of a nontrivial topological structure in a band insulator without any magnetic field.

description: Based on a critique of the popular assumption that teenagers participate in sexual relationships within a context of mutuality, equality and personal choice, a conceptual model is developed which examines gender differences in characteristics of power and dependency and how these factors help explain patterns of teenage sexual behavior. Drawing on the basic ideas of power-dependency theory, a multistage 12-variable path model is used to analyze a set of secondary data on teenage sexual behavior. The data analyzed come from a 1984 survey of a sample of 326 Ohio teenagers. The data are disaggregated to examine gender differences in sexuality among three groups, white teenagers, teenagers of color and teenagers who have had at least one experience of full sexual intercourse. Multiple regression and path analytic techniques are used to identify the ways in which measures of dependency (feelings of discomfort with physical appearance, the need for self-disclosure and closeness, the need for physical gratification in sex and the need for emotional gratification in sex) intervene between power-enhancing attributes (confidence with members of the opposite sex, popularity, the extent to which the friendship network is primarily of the opposite sex and egalitarian gender role attitudes) and sexual activity (participation in unwanted sex and the extent of intimate sexual behavior). It is hypothesized that attributes of power will decrease sexual activity through their diminishing effect on the dependency measures. As hypothesized, the power attributes have important indirect negative effects which decrease sexual activity for males through their diminishing influence on the measures of dependency. While many of the power attributes tend to decrease dependency for the females, few of these measures directly influence sexual activity at the high levels observed for the males. Although few gender differences are found in the white and the sexually-experienced subgroups, important differences are observed between the females and males of color. The females of color appear to be uniquely in control of their sexual experiences when compared to the rest of the teens in the sample, both male and female.

description: Architecture-based heat dissipation analyses allow us to reveal fundamental sources of inefficiency in a given processor and thereby provide us with road-maps to design less dissipative computing schemes independent of technology-base used to implement them. In this work, we study architectural-level contributions to energy dissipation in an Artificial Neural Network (ANN)-based processor that is trained to perform edge-detection task. We compare the training and information processing cost of ANN to that of conventional architectures and algorithms using 64-pixel binary image. Our results reveal the inherent efficiency advantages of an ANN network trained for specific tasks over general-purpose processors based on von Neumann architecture. We also compare the proposed performance improvements to that of Cellular Array Processors (CAPs) and illustrate the reduction in dissipation for special purpose processors. Lastly, we calculate the change in dissipation as a result of input data structure and show the effect of randomness on energetic cost of information processing. The results we obtained provide a basis for comparison for task-based fundamental energy efficiency analyses for a range of processors and therefore contribute to the study of architecture-level descriptions of processors and thermodynamic cost calculations based on physics of computation.

description: The one-loop structure of the trace anomaly is investigated using different regularizations and renormalization schemes: dimensional, proper time and Pauli-Villars. The universality of this anomaly is analyzed from a very general perspective. The Euler and Weyl terms of the anomalous trace of the stress tensor are absolutely universal. The pure derivative $ \square R$-term is shown to be universal only if the regularization breaks conformal symmetry softly. If the breaking of conformal symmetry by the regularization method is hard the coefficient of this term might become arbitrary which points out the presence of an ambiguous $ \int\sqrt{-g} R^2$-term in the effective quantum action. These ambiguities arise in some prescriptions of dimensional and Pauli-Villars regularizations. We discuss the implications of these results for anomaly-induced inflationary scenarios and AdS/CFT correspondence.

Modulation of cellular transglutaminase: Isolation and characterization of transglutaminases from guinea pig epidermis
Creators: name: Kim, Hee Chul
Publisher: name: American University
Year: 2023

description: Transglutaminases are calcium-dependent enzymes that catalyze the formation of covalent $\varepsilon(\gamma$-glutamyl)lysine cross-links in proteins. A cationic proenzyme form of epidermal transglutaminase (protransglutaminase E) has been isolated from epidermis of new born mouse and from adult guinea pig. Upon activation, this zymogen is the source of most of the extractable enzyme activity in epidermis and skin. The molecular mass of protransglutaminase E determined by sedimentation equilibrium was 77,800 and was similar to the value estimated by SDS-PAGE. Dispase or thrombin treatment of the proenzyme resulted in an 80-fold activation of transglutaminase activity. In the nondenatured state, the Dispase-activated enzyme was shown by gel permeation and sedimentation equilibrium methods to be the same molecular size as the proenzyme. In the denatured state, the enzyme consisted of two peptide fragments of M$\sb{\rm r}$ 50,000 and M$\sb{\rm r}$ 27,000, as analyzed by SDS-PAGE under non-reducing conditions. The activated epidermal transglutaminase showed a thiol dependency for full enzyme activity as well as a low Ca$\sp{2+}$ ion requirement (Ka $<$ 10$\sp{-10}$ M). High levels of Ca$\sp{2+}$ ion induced a concentration dependent activation of proenzyme in a reversible manner. The purified zymogen from guinea pig skin displayed higher glycine, serine, and alanine contents then guinea pig liver transglutaminase. Westernbolt analysis of three different forms of transglutaminase present in epidermis, with monospecific polyclonal antibodies to protransglutaminase E, showed non-identity with either the membrane-associated transglutaminase or the cytosolic tissue transglutaminase. These results indicate that a substantial portion of the total transglutaminase in skin occurs as proenzyme form of the epidermal transglutaminase and that activation could be induced by neutral protease and Ca$\sp{2+}$ ions that are made available during the terminal differentiation of epidermal calls into the cornified layers of skin.

description: We consider the problems of calculating the dynamical order parameter two-point function at finite temperatures and the one-point function after a quantum quench in the transverse field Ising chain. Both of these can be expressed in terms of form factor sums in the basis of physical excitations of the model. We develop a general framework for carrying out these sums based on a decomposition of form factors into partial fractions, which leads to a factorization of the multiple sums and permits them to be evaluated asymptotically. This naturally leads to systematic low density expansions. At late times these expansions can be summed to all orders by means of a determinant representation. Our method has a natural generalization to semi-local operators in interacting integrable models.

description: A theory is proposed that explains how rule emerges among independent rational actors. Most international relations theory assumes that anarchy is the defining characteristic of the international system. Anarchy, however, is an ideal rather than an empirical reality. This is especially true if anarchy is conceptualized as the absence of rule rather than the absence of government. Where anarchy implies uncertainty, rule implies order. An axiomatic theory is presented that shows that in an infinitely iterated sequential game, there is an inevitable tendency for rational actors to create rules and for conditions of rule to emerge. A field theoretic conception of power is developed to define rules and conditions of rule. A rational actor will use power to change the utility calculus of its opponent in order to persuade the opponent to perform actions that the actor desires. An actor can affect the opponent's choice of action by changing the opponent's subjective probability of the actor's response, by changing the opponent's utility gained from various outcomes, or by changing the set of actions that are available to the opponent. Rule results from rational actors using these power mechanisms to reduce the uncertainty in their environment. Hypotheses derived from the theory of rule are tested by simulating games that are commonly used to model international relations. The tests show that conflictual games such as the Prisoner's Dilemma and the Chicken game produce cooperative outcomes if the players are sufficiently interested in future benefits and if the opponent's subjective probability of the actor's response is skewed toward a rule condition. Two empirical cases are examined to illustrate the emergence of rule in real world settings. These two cases are the development of the Rules of the Road at Sea and the shift away from the gold standard between the two world wars.

description: We study the wave equation for a massive scalar field in three-dimensional AdS-black hole and dS (de Sitter) spaces to find what is the difference and similarity between two spaces. Here the AdS-black hole is provided by the J=0 BTZ black hole. To investigate its event (cosmological) horizons, we compute the absorption cross section, quasinormal modes, and study the AdS(dS)/CFT correspondences. Although there remains an unclear point in defining the ingoing flux near infinity of the BTZ black hole, quasinormal modes are obtained and the AdS/CFT correspondence is confirmed. However, we do not find quasinormal modes and thus do not confirm the assumed dS/CFT correspondence. This difference between AdS-black hole and dS spaces is very interesting, because their global structures are similar to each other.

description: A vortex lattice ratchet effect has been investigated in Nb films grown on arrays of nanometric Ni triangles, which induce periodic asymmetric pinning potentials. The vortex lattice motion yields a net dc-voltage when an ac driving current is applied to the sample and the vortex lattice moves through the field of asymmetric potentials. This ratchet effect is studied taking into account the array geometry, the temperature, the number of vortices per unit cell of the array and the applied ac currents.

description: The ASPIRE program, which is based on the Landau singularities and the method of power geometry to unveil the regions required for the evaluation of a given Feynman diagram asymptotically in a given limit, also allows for the evaluation of scaling coming from the top facets. In this work, we relate the scaling having equal components of the top facets of the Newton polytope to the maximal cut of given Feynman integrals. We have therefore connected two independent approaches to the analysis of Feynman diagrams.

description: The Jacobi identity is the key relation in the definition of a Lie algebra. In the last decade, it also appeared at the heart of the theory of finite type invariants of knots, links and 3-manifolds (and is there called the IHX-relation). In addition, this relation was recently found to arise naturally in a theory of embedding obstructions for 2-spheres in 4-manifolds. We expose the underlying topological unity between the 3- and 4-dimensional IHX-relations, deriving from a picture of the Borromean rings embedded on the boundary of an unknotted genus three handlebody in 3-space. This is most naturally related to knot and 3-manifold invariants via the theory of grope cobordisms.

description: This paper examines the behavior of utility-maximizing migrants in a system of guest-worker migration. Their pattern of leisure and commodity consumption at honie and abroad is analysed and related to those chosen by the natives of the host country and the non-migrants of the source country. The paper also highlights an important distinction between permanent and temporary migration. While a permanent migrant is primarily interested in the real-wage differential between countries of immigration and emigration, a guest worker's decision to migrate depends on both the real and the nominal differential. The relative importance of the nominal differential is found to be inversely related to the degree of concavity of his instantaneous utility function.

description: When working on intelligent tutor systems designed for mathematics education and its specificities, an interesting objective is to provide relevant help to the students by anticipating their next steps. This can only be done by knowing, beforehand, the possible ways to solve a problem. Hence the need for an automated theorem prover that provide proofs as they would be written by a student. To achieve this objective, logic programming is a natural tool due to the similarity of its reasoning with a mathematical proof by inference. In this paper, we present the core ideas we used to implement such a prover, from its encoding in Prolog to the generation of the complete set of proofs. However, when dealing with educational aspects, there are many challenges to overcome. We also present the main issues we encountered, as well as the chosen solutions.

description: This paper is concerned with the general problem of testing one form of covariance structure against another in a normal linear regression. It is shown that all the point-optimal tests recently proposed by King and his associates can be interpreted as special cases of a Cox test for non-nested hypotheses. This provides a synthesis of a whole range of point-optimal tests as well as demonstrating that King and his associates have exposed a class of Cox tests which have an exact distribution.
A psychological and economic model of straight ticket, split ticket, single ticket, and nonvoting: Party identification and spatial voter choice in the American national election of 1984
Creators: name: Semiatin, Richard Jeffrey
Publisher: name: American University
Year: 2023

description: This dissertation hypothesizes a psychological and economic model of voting behavior. The model posits that party identification (an implicit psychological model) and spatial voter choice (an implicit economic model) can predict straight ticket, split ticket, single ticket, and nonvoting. The psychological theory is represented by a party identification model. The economic theory is represented by the Downsian model of spatial voter choice, and a model of spatial candidate choice introduced in this model. Moreover, this dissertation hypothesizes that both theories represent a more complete model and is statistically different from the varying models of party identification and spatial voter choice. The parameters of the party identification and spatial voter choice coefficients are estimated by a logit model utilizing American National Election Series survey data from 1984. Results indicated that the full model significantly differs from each individual model. The implications are that voting and nonvoting decisions are viewed as a process representing a current tally of evaluations of psychological and spatial voter choice variables.

We first review a number of results about these tests in linear regression models, and present some new material on their distribution when the model being tested is false, and on a simple way to improve their power in certain cases. We then show how in a general nonlinear setting they may be computed as "score" tests by means of slightly modified versions of any artificial linear regression that can be used to calculate Lagrange Multiplier tests, and explore some of the implications of this result. In particular, we show how to create a variant of the information matrix test that tests for parameter consistency. We examine both the conventional information matrix test and our new version in the context of binary choice models, and provide a simple way to compute both tests based on artificial regressions. Some Monte Carlo evidence is also presented; it suggests that the most common form of the information matrix test can be extremely badly behaved in samples of even quite large size.

description: This dissertation hypothesizes a psychological and economic model of voting behavior. The model posits that party identification (an implicit psychological model) and spatial voter choice (an implicit economic model) can predict straight ticket, split ticket, single ticket, and nonvoting. The psychological theory is represented by a party identification model. The economic theory is represented by the Downsian model of spatial voter choice, and a model of spatial candidate choice introduced in this model. Moreover, this dissertation hypothesizes that both theories represent a more complete model and is statistically different from the varying models of party identification and spatial voter choice. The parameters of the party identification and spatial voter choice coefficients are estimated by a logit model utilizing American National Election Series survey data from 1984. Results indicated that the full model significantly differs from each individual model. The implications are that voting and nonvoting decisions are viewed as a process representing a current tally of evaluations of psychological and spatial voter choice variables.

description: The paper deals with cosmological solutions describing different phases of the Universe for the homogeneous and isotropic FLRW model of the Universe with torsion. Normally, torsion field is not suitable for maximally symmetric space time model. However, one may use a specific profile of vectorial torsion field, derived from a scalar function. By proper choices of the torsion scalar function, it is shown that a continuous cosmic evolution starting from the emergent scenario to the present late time acceleration is possible. Also thermodynamics of the system is analyzed and equivalence with Einstein gravity is discussed.

description: Oxygen, the third most abundant element in the universe, plays a key role in the chemistry of condensed matter and biological systems. Here, we report evidence for a hitherto unexplored Auger transition in oxides, where a valence band electron fills a vacancy in the 2s state of oxygen, transferring sufficient energy to allow electron emission. We used a beam of positrons with kinetic energies of $\sim$1 eV to create O 2s holes via matter-antimatter annihilation. This made possible the elimination of the large secondary electron background that has precluded definitive measurements of the low-energy electrons emitted through this process. Our experiments indicate that low-energy electron emission following the Auger decay of O 2s holes from adsorbed oxygen and oxide surfaces are very efficient. Specifically, our results indicate that the low energy electron emission following the Auger decay of O 2s hole is nearly as efficient as electron emission following the relaxation of O 1s holes in TiO$_2$. This has important implications for the understanding of Auger-stimulated ion desorption, Coulombic decay, photodynamic cancer therapies, and may yield important insights into the radiation-induced reactive sites for corrosion and catalysis.

Press coverage of selected members of the Senate Foreign Relations Committee and House Foreign Affairs Committee in their states and districts

description: This research analyzed the foreign affairs news coverage of 18 members of the Senate Foreign Relations Committee and House Foreign Affairs Committee in newspapers back in their home states and districts. The study drew on previous research in two areas--Congress and the news media, and the international flow of news. Data was generated by three sources: a content analysis of news in 18 daily newspapers around the country, plus one national newspaper, the Washington Post; a content analysis of the news releases distributed by members of the two committees; and interviews conducted with press secretaries, journalists, and others. The study found the foreign affairs coverage to be a mere trickle rather than a genuine flow with much more attention going to domestic issues. Members and journalists agreed that the public is more interested in news about domestic issues that could be more easily related to such everyday concerns as jobs, pollution, and crime. The foreign affairs coverage that did appear was not well rounded. It emphasized only a few countries and issues. National security concerns dominated the coverage--wars in Nicaragua and the Persian Gulf, the loss of intelligence secrets to the Soviet Union, weapons sales to foreign countries, and covert operations. Other important issues on the world agenda went uncovered--for example, environmental deterioration and the disease, poverty, hunger, and other ills that beset the developing countries. The coverage reflected a strong East-West orientation. One key to generating press coverage back home was to find a local angle to foreign affairs in one of three ways: issues that combined domestic and international dimensions (intermestic issues), especially trade with its emphasis on jobs; issues of special interest to ethnic groups in the community; and initiatives by local organizations and individuals--for example, interest groups that try to influence a senator's vote on a foreign affairs issue. For a number of reasons, the coverage of members of Congress in newspapers back in their home states makes only a minimal contribution toward creating an informed public on foreign affairs.

description: Structural induction is a proof technique that is widely used to prove statements about discrete structures. Students find it hard to construct inductive proofs, and when learning to construct such proofs, receiving feedback is important. In this paper we discuss the design of a tutoring system, LogInd, that helps students with constructing stepwise inductive proofs by providing hints, next steps and feedback. As far as we know, this is the first tutoring system for structural induction with this functionality. We explain how we use a strategy to construct proofs for a restricted class of problems. This strategy can also be used to complete partial student solutions, and hence to provide hints or next steps. We use constraints to provide feedback. A pilot evaluation with a small group of students shows that LogInd indeed can give hints and next steps in almost all cases.

description: Artificial linear regressions often provide a convenient way to calculate test statistics and estimated covariance matrices. This paper discusses one family of these regressions, called "double-length" because the number of "observations" in the artificial regression is twice the actual number of observations. These double-length regressions can be useful in a wide variety of situations. They are quite easy to calculate, and seem to have good properties when applied to samples of modest size. We first discuss how they are related to the more familiar Gauss-Newton and squared-residuals regressions for nonlinear regression models, then show how they may be used to test for functional form, and finally discuss several other ways in which they may be useful in applied econometric work.

description: We revisit and present new linear spaces of explicit solutions to incompressible Euler and Navier-Stokes equations on $\mathbb{R}^n$, as well as the rotating Boussinesq equations on $\mathbb{R}^3$. We cast these solutions are superpositions of certain linear plane waves of arbitrary amplitudes that also solve the nonlinear equations by constraints on wave vectors and flow directions. For $n\leq 3$ these are explicit examples for generalized Beltrami flows. We show that forcing terms of corresponding plane wave type yield explicit solutions by linear variation of constants. We work in Eulerian coordinates and distinguish the two situations of vanishing and of gradient nonlinear terms, where the nonlinear terms modify the pressure. The methods, that we introduce to find explicit solutions in some nonlinear fluid models, can also be used in other equations with material derivative. Our approach offers another view on known explicit solutions of different fluid models from a plane wave perspective, and provides transparent nonlinear interactions between different flow components.
