Using Geologic and Geodetic Analyses to Define the Location, Slip Rate, and Geometry of Off Fault Deformation, Hidden Spring Fault Zone, Southern California

A strain deficit of about 10 mm/yr exists across the San Andreas Fault system on the boundary between the North American and Pacific plates. We investigate the role of the Hidden Spring Fault Zone, east of the Salton Sea in Southern California, and related structures in accommodating some of this slip. We compile data from historic and current aerial and satellite imagery, coupled with UAVSAR and LiDAR data have allowed us to identify and map hundreds of new fault segments in the region. Where possible, we correlate some of these data with geologic evidence for the faults. These data emphasize the orientations and potential fault linkages that are vital for a kinematic analysis of the Hidden Spring Fault Zone and in creating a baseline analysis of deformation in a region where large seismic ruptures are likely to occur

Adult Learning and the Shrinking Globe

The purpose of this roundtable is to explore the evolution of Adult Education in several European nations relative to the United States and the advantages of the broadened European vision of adult learning as lifelong-lifewide. Through examining these practices we may discover options for inclusion in the United States

The Role of Functional, Social, and Mobility Dynamics in Facilitating Older African Americans Participation in Clinical Research

Purpose: Older African Americans experience disproportionately higher incidence of morbidity and mortality related to chronic and infectious diseases, yet are significantly underrepresented in clinical research compared to other racial and ethnic groups. This study aimed to understand the extent to which social support, transportation access, and physical impediments function as barriers or facilitators to clinical trial recruitment of older African Americans. Methods: Participants (N=221) were recruited from six African American churches in Atlanta and surveyed on various influences on clinical trial participation

Hypercube technology

The JPL designed MARKIII hypercube supercomputer has been in application service since June 1988 and has had successful application to a broad problem set including electromagnetic scattering, discrete event simulation, plasma transport, matrix algorithms, neural network simulation, image processing, and graphics. Currently, problems that are not homogeneous are being attempted, and, through this involvement with real world applications, the software is evolving to handle the heterogeneous class problems efficiently

Violence and the limits of modern liberalism: the political novels of Joseph Conrad

Conrad wrote in his political essay, ‘Autocracy and War,’ of the inevitable degradation of political ideals in the cut and thrust of actual politics. This thesis proposes that Conrad’s political novels are fundamentally engaged with modern liberalism. It places Conrad’s political novels in conversation with modern liberal political theory, arguing that close attention to aesthetic concerns is illuminating of the latter’s limits. Violence is abhorred by modern liberalism as a fundamental limit on liberty, yet Conrad’s writing posits violence as ubiquitous in modern liberal politics. Freedom itself is presented in his work as a form of violence; additionally, core liberal concerns––conversation, the public/private split, autonomy, the individual self––are implicated in different forms of violence that tend to perpetuate an unequal status quo. In Conrad’s writing, these all appear as limits on freedom, thus modern liberalism is represented as a negotiation of competing forms of violence. However, Conrad’s self-contradictory writing both undermines and unexpectedly affirms modern liberalism, at least in part. These critiques emerge not from conceptual analysis, but rather from close attention to issues of literary form: in particular, Conrad’s modernist aesthetic, dialogic narrative, and complex use of genre. In terms of the latter, both romance and burlesque infiltrate realist fiction, bringing with them a range of contradictory politics. Via these generic interactions, Conrad finds the origins of modern liberalism in an archaic politics based in elite feudal values that were historically involved in the regulation of violence. This archaic value system is degraded by the democratic impulse of burlesque. Conrad is unable to commit wholeheartedly to either archaic feudalism or modern liberalism, and elitism and democracy appear as two further limits to the latter. Against the grain, perhaps, it is the very debasement of feudal mores by populism that enables modern liberalism’s partial recuperation in Conrad’s work

Computing Fault Displacements from Surface Deformations

Simplex is a computer program that calculates locations and displacements of subterranean faults from data on Earth-surface deformations. The calculation involves inversion of a forward model (given a point source representing a fault, a forward model calculates the surface deformations) for displacements, and strains caused by a fault located in isotropic, elastic half-space. The inversion involves the use of nonlinear, multiparameter estimation techniques. The input surface-deformation data can be in multiple formats, with absolute or differential positioning. The input data can be derived from multiple sources, including interferometric synthetic-aperture radar, the Global Positioning System, and strain meters. Parameters can be constrained or free. Estimates can be calculated for single or multiple faults. Estimates of parameters are accompanied by reports of their covariances and uncertainties. Simplex has been tested extensively against forward models and against other means of inverting geodetic data and seismic observations. This wor
