Two-Temperature Discrete Model For Nonlocal Heat Conduction, Sergey Sobolev

Sergey Sobolev

The two-temperature discrete model for heat conduction in heterogeneous media is proposed. It is shown that the discrete model contains as limiting cases both hyperbolic and parabolic heat conduction equations for propagative and diffusive regimes, respectively. To obtain these limiting cases two different laws of continuum limit have been introduced. The evolution of the two-temperature system comprises three stages with distinct time scales : fast relaxation of each subsystem to local equilibrium, energy exchange between the subsystems and classical hydrodynamics.

Who Enrolled In A State Program For The Uninsured: Was There Adverse Selection?, Paula Diehr

Paula Diehr

Managed care plans may hesitate to participate in programs for uninsured persons because they fear adverse selection, whereby only the sickest people or highest users would choose to join the program. We studied this issue in Washington State's Basic Health Plan, a demonstration program that provides subsidized health insurance for families earning less than 200% of the poverty level. We interviewed people in three counties who enrolled in the program, and compared them to people in the same counties who were eligible but did not enroll. There were substantial differences between enrollees and eligibles in education, age, income, employment, race, …

'Quality Ladders' And Ricardian Trade, M. Scott Taylor

M. Scott Taylor

A Model of endogenous growth and trade is developed that extends the continuum Ricardian model of Dornbusch et al. (1977) to a dynamic framework, generalizes the 'Quality ladders' approach of Grossman and Helpman (1991a,b), and complements the work of Krugman (1987) on dynamic Ricardian economies. In contrast to earlier work the model incorporates heterogeneity across industries in research and production technologies, and in the technological opportunity for innovation. The importance of heterogeneity is demonstrated through a comparative steady-state analysis. Several applications for the model are discussed and many others appear possible given its relatively simple structure.

Power Output And Propulsive Efficiency Of Swimming Bottle-Nosed Dolphins (Tursiops-Truncatus), Frank E. Fish

Frank E. Fish

The power output and propulsive efficiency of swimming bottlenose dolphins (Tursiops truncatus) were determined from a hydromechanical model. The propulsive movements were filmed as dolphins swam in large pools. Dolphins swam at velocities of 1.2-6.0 m s-1. Propulsion was provided by dorsoventral oscillations of the posterior body and flukes. The maximum angle of attack of the flukes showed a linear decrease with velocity, whereas the frequency of the propulsive cycle increased linearly with increasing velocity. Amplitude was 20 % of body length and remained constant with velocity. Propulsive efficiency was 0.81. The thrust power computed was within physiological limits. After …

Association Of K-1 Capsule, Smooth Lipopolysaccharides, Trat Gene, And Colicin V Production With Complement Resistance And Virulence Of Avian Escherichia Coli, Richard E. Wooley, Lisa K. Nolan, John Brown, Penelope S. Gibbs, Catherine W. Giddings, Kathy S. Turner

Lisa K. Nolan

A group of complement-resistant, virulent avian Eschberichia coli isolates were compared with a group of complement-sensitive, avirulent avian isolates for the presence of K-1 capsule, smooth lipopolysaccharides (LPS), the traT gene, and Colicin V (ColV) production. These parameters were selected because of their reported association with complement resistance and virulence in E. coli. Lethality in chicken embryos has also been shown to be correlated with virulence of avian E. colifor chickens. The complement-resistant, virulent E. coli isolates did not possess a K-1 capsule. Production of ColV and the presence of smooth LPS were significantly correlated with embryo lethality. There was …

Relatedness And Performance: A Reexamination Of The Diversification-Performance Link, John Y. Ding, Julie Caswell, Furen Zhou

Julie Caswell

Empirical studies of firm diversification suggest the existence of a positive relationship between the relatedness of diversification and firm performance. Using evidence from the food manufacturing sector, we find that this relationship is weak at best and that market share appears to be a more powerful predictor of firm performance.

Predicting Birth Weight: Relative Importance Of Sociodemographic, Medical, And Prenatal Care Variables, Terri Combs-Orme, Christina Rtisley-Curtiss, Ronald Taylor

Terri Combs-Orme

This study uses the 1980 National Natality Study to examine the relative importance of sociodemographic factors, medical-risk factors, and prenatal care in predicting birth weight. Findings indicate that both sociodemographic and medical-risk factors are important in predicting birth weight, with medical risks accounting for slightly more variance (after accounting for social variables) in birth weight. Although prenatal care accounts for only 1 percent of the variance, a statistical interaction between prenatal care and labor complications accounts for an additional 1 percent.

A Reinterpretation Of Some Bay Area Shellmound Sites: A View From The Mortuary Complex From Ca-Ala-329, The Ryan Mound, Alan M. Leventhal

Alan M. Leventhal

This monograph is a slightly revised and updated version of my 1993 thesis A Reinterpretation of Some Bay Area Shellmound Sites: A View from the Mortuary Complex from Ca-Ala-329, the Ryan Mound. This study addresses the archaeological assemblages derived from prehistoric site Ca-Ala-329, and applies generated data to pre-existing settlement-subsistence models developed for central California and the San Francisco Bay. When these data failed to conform neatly to the expected pattern of shellmounds-as-villages model, alternative explanations had to be explored. Alternative explanations were developed by critically evaluating the treatment of comparable published archaeological data from other San Francisco Bay shellmounds …

La Gestión Urbana: Estrategías, Dilemas Y Retos, Fernando Carrión Mena

Fernando Carrión Mena

A pesar de la importancia creciente que ha ido adquiriendo el tema ambiental, su avance teórico en relación con la ciudad es insuficiente; al extremo de que aún no se ha logrado construir un marco conceptual que establezca las respectivas mediaciones y relaciones con lo urbano, la planificación y la gestión. No hay una visión integrada o cuando menos integradora; de allí que en este mundo de dicotomías, el maniqueísmo tienda a salir a flote: mientras lo natural, lo rural, el campo son lo bueno, lo artificial, lo urbano, la ciudad son lo malo. En este contexto se ha satanizado, …

Constitutional Design And Law: The Political Economy Of Cabinet And Congressional Government, Matthew S. R. Palmer

The Hon Justice Matthew Palmer

The dissertation takes a political economy approach to constitutional design and legislation in the Westminster (Cabinet) and US (Congressional) models of government. Part I develops the economics of comparative political organization by constructing a theoretical framework for analyzing constitutional design. Part II applies the framework to distinguish the essences of the Cabinet and Congressional systems of constitutional design in the contexts of US and Canadian federal government. Part III analyzes the effects of the different constitutional designs on the processes of legislating in each system and on the substantive characteristics of legislation in each system. The analysis is subjected to …

Brittle Composites Modeling: Compazisons With Mosi2/Zro2, S.P. Chen, Richard Alan Lesar, A. D. Rollett

Richard Alan Lesar

We have calculated the mechanical properties of brittle composites with spring-network (SN) model. The composites that we studied involve the transformation toughening effects and the accompanying micro-cracking. Our simulation results are consistent with experiments of MoSi2 toughened with ZrO2. By monitoring the stress changes due to the transformation and micro-cracking we are able to separate, for the first time, the contributions from these two competing effects. We also found that the fracture toughness of the composite increases as the modulus, interfacial cohesion of particle increases.

Session Duration And The Vi Response Function: With-In Session Prospective And Retrospective Efffects, James Dougan, Alfred Kuh, K. Vink

James Dougan

Two experiments examined the effects of session duration on responding during simple variable-interval schedules. In Experiment 1, rats were exposed to a series of simple variable-interval schedules differing in both session duration (10 min or 30 min) and scheduled reinforcement rate (7.5 s,15 s, 30 s, and 480 s). The functions relating response rate to reinforcement rate were predominantly monotonic for the short (10-min) sessions but were predominantly bitonic for the long (30-min) sessions, when data from the entire session were considered. Examination of responding within sessions suggested that differences in the whole-session data were produced by a combination of …
