Compact Routing In Fault-Tolerant Distributed Systems, James Edward Lawrence Jan 1997

Compact Routing In Fault-Tolerant Distributed Systems, James Edward Lawrence

UNLV Retrospective Theses & Dissertations

A compact routing algorithm is a routing algorithm which reduces the space complexity of all-pairs shortest path routing. Compact routing protocols in distributed systems have been studied extensively as an attractive alternative to the traditional method of all-pairs shortest path routing. The use of compact routing protocols have several advantages. Compact routing schemes are not only more memory-efficient, but provide faster routing table lookup, more efficient broadcast scheme, and allow for a more scalable network. These routing schemes still maintain optimal or near-optimal routing paths. However, most of the compact routing protocols are not fault-tolerant. This thesis will first report …

Generation X: A Social Movement Toward Cynicism, Paula Gottula Miles Jan 1997

Generation X: A Social Movement Toward Cynicism, Paula Gottula Miles

UNLV Retrospective Theses & Dissertations

In the past twenty-five years Americans have shifted from modern values of reason, science, and progress, to postmodern values of cynicism and relativism. Due to the different social climate and the ubiquitous mass media, Generation Xers--those born between 1960 and 1980--are the first to be socialized from infancy to possess postmodern values. Because of this dramatic shift in values, Generation X can be viewed as an intellectual or cultural social movement, in the sense of a social movement being a collective change in values over time. This study examines the differing values of Generation X by comparing their values to …

The Vietnam War: A Comparison Of Interpretations, David Scott Morokoff Jan 1997

The Vietnam War: A Comparison Of Interpretations, David Scott Morokoff

UNLV Retrospective Theses & Dissertations

This thesis is based on a quantitative analysis of Time magazine's coverage of the Vietnam War. It demonstrates that Time held a pro-war bias in 1967, was neutral during 1968, and turned strongly against the war from 1969 through 1974. From mid-1969 on, some articles factually misrepresented what was happening in Vietnam in such a way as to promote the goals of the anti-war movement. If events admitted of both a pro-war and an anti-war interpretation Time published almost exclusively the anti-war view. By 1972, administration supporters had published a large body of verifiable evidence (summarized in chapter 3) demonstrating …

When Playing God: Concerning Artificial Reproduction, Christina Ann Brandom Sessa Jan 1997

When Playing God: Concerning Artificial Reproduction, Christina Ann Brandom Sessa

UNLV Retrospective Theses & Dissertations

This thesis is a discussion about new reproductive technologies and the ethical implications of those technologies. Until now, fetal personhood was the focus of pro-choice and pro-life groups battling about abortion versus women's rights. However, new reproductive technologies such as in vitro fertilization and cryopreservation further complicate the foundation upon which traditional abortion arguments are based. The focus of the argument should be shifted from fetal personhood to a more comprehensive argument for the respect of the sanctity of human life. This shift would force society to address the more crucial issues which have led us to abortion and new …
