Curbing Urban Traffic Congestion In Singapore: A Comprehensive Review, Rex S. Toh, Sock-Yong Phang Dec 1997

Curbing Urban Traffic Congestion In Singapore: A Comprehensive Review, Rex S. Toh, Sock-Yong Phang

Research Collection School Of Economics

One of the most pervasive and frustrating of modern transportation problems is urban traffic congestion. Since 1975, Singapore has introduced a relentless series of traditional and experimental measures to slow down the growth of the motor vehicle population and to control its usage. While some of the measures have been somewhat successful, some of the problems were shifted or were substituted. The Area Licensing Scheme led to a shifting of the problem in time and place while the quota system has substituted uncertainty in quantity with uncertainty in price. Furthermore, the Preferential Additional Registration Fee system and the Quota System …

Anthroposophic Perspectives In Primary Care, Ira S. Cantor Md, Steven Rosenzweig Md Dec 1997

Anthroposophic Perspectives In Primary Care, Ira S. Cantor Md, Steven Rosenzweig Md

Department of Emergency Medicine Faculty Papers

A core challenge of contemporary medicine is to integrate the technological successes of biomedical science with a comprehensive under-standing of the physical, psychosocial, ecological, and spiritual dimensions of health and illness. Toward this end, bridges are being created between conventional medicine and alternative systems of healing which reflect a holistic model of the human being. Even when both conventional and complementary approaches are used side-by-side in the same patient, they remain separate in their basic assumptions and goals. Today's mechanistic disease model is cut off from such notions as life-energy, consciousness, and spirituality, so integral to many alternative paradigms. Anthroposophically …

Jury Reform: Of Myths And Moral Panics, Peter Duff, Mark Findlay Dec 1997

Jury Reform: Of Myths And Moral Panics, Peter Duff, Mark Findlay

Research Collection Yong Pung How School Of Law

It is now commonplace to assert that the jury performs an important ideological or symbolic role in the criminal justice process. Indeed, it is often argued that this function is more significant than the impact the jury has in practice (see Mungham & Bankowski 1976; Duff & Findlay 1982; Findlay & Duff 1988: 1–7; Darbyshire 1991). Certainly it is true that, in virtually every jurisdiction where the jury exists, only a very small proportion of alleged offenders have their cases heard before a jury. There are two principal reasons for this. First, the vast majority of those charged with criminal …

Physician Assisted Suicide And The Supreme Court: Putting The Constitutional Claim To Rest, Wendy K. Mariner Dec 1997

Physician Assisted Suicide And The Supreme Court: Putting The Constitutional Claim To Rest, Wendy K. Mariner

Faculty Scholarship

Like the debate about many controversial questions of ethics and medical care in America, public debate about physician assisted suicide became focused on questions of constitutional law. On June 26, 1997, the United States Supreme Court unanimously rejected any constitutional right of terminally ill patients to physician assisted suicide. An analysis of the Court's reasoning reveals that its decisions resolved only a narrow constitutional question that affects relatively few people--mentally competent, terminally ill patients who wish to hasten their imminent deaths by having a physician prescribe medication that they intend to use to commit suicide. Although suicide is not a …

In Search Of A Substantive Republic, James E. Fleming, Linda C. Mcclain Dec 1997

In Search Of A Substantive Republic, James E. Fleming, Linda C. Mcclain

Faculty Scholarship

The publication of Michael J. Sandel's Democracy's Discontent: America in Search of a Public Philosophy is a long-awaited and important event in political and constitutional theory. In 1982, through his first book, Liberalism and the Limits of Justice,1 Sandel emerged as a leading communitarian or civic republican critic of liberalism. That book became prominent, not because its criticisms of liberalism were dispositive, but because it eloquently and elegantly captured discontent with liberalism and evoked yearnings for an alternative. Since then, Sandel has occupied a position on the American intellectual landscape as a placeholder for a *510 communitarian or civic …

A System Dynamics Investigation Of Environmental Attitudes And Behaviors Influencing Solid Waste Reduction, Louis E. Lilley Dec 1997

A System Dynamics Investigation Of Environmental Attitudes And Behaviors Influencing Solid Waste Reduction, Louis E. Lilley

Theses and Dissertations

The relationship between attitudes and behavior is investigated in regard to the reduction of solid waste in a community. The theory of reasoned action, as identified by Ajzen and Fishbein in 1975, is investigated using as system dynamics approach. The closed loop system structure that would produce the expected real world response is established. The structure is then translated into a flow diagram and coded into a mathematical model. The model quantifies the values of beliefs, attitudes, intentions, behaviors, external and demographic variables, perceptions, and waste generation levels in order to illustrate how each changes over time when influenced by …

Cepstral Processing For Gps Multipath Detection And Mitigation, Charles D. Ormsby Dec 1997

Cepstral Processing For Gps Multipath Detection And Mitigation, Charles D. Ormsby

Theses and Dissertations

This work presents a novel approach to code phase multipath mitigation for Global Positioning System (GPS) receivers. It uses the power and complex cepstra for multipath detection and mitigation prior to code phase tracking by a standard non-coherent delay lock loop. Cepstral theory is presented to demonstrate how multipath reflection delays can be detected through the use of the power cepstrum. Filtering can then be performed on the complex cepstrum to remove multipath effects in the cepstral domain. Finally, an inverse complex cepstrum is calculated yielding a theoretically multipath free direct path estimate in the time domain. Simulations are presented …

A Dichotomous Role For Nitric Oxide During Acute Toxoplasma Gondii Infection In Mice, Imtiaz A. Khan, Joseph D. Schwartzman, Tadashi Matsuura, Lloyd H. Kasper Dec 1997

A Dichotomous Role For Nitric Oxide During Acute Toxoplasma Gondii Infection In Mice, Imtiaz A. Khan, Joseph D. Schwartzman, Tadashi Matsuura, Lloyd H. Kasper

Dartmouth Scholarship

Production of nitric oxide by macrophages is believed to be an important microbicidal mechanism for a variety of intracellular pathogens, including Toxoplasma gondii. Mice with a targeted disruption of the inducible nitric oxide synthase gene (iNOS) were infected orally with T. gondii tissue cysts. Time to death was prolonged compared with parental controls. Histologic analysis of tissue from infected mice showed scattered small foci of inflammation with parasites in various tissues of iNOS−/− mice, whereas tissue from the parental C57BL/6 mice had more extensive tissue inflammation with few visible parasites. In particular, extensive ulceration and necrosis of distal small …

An Investigation Of Plume Rise From Titan Iv Rocket Launches, Joseph D. Brands Dec 1997

An Investigation Of Plume Rise From Titan Iv Rocket Launches, Joseph D. Brands

Theses and Dissertations

Space launches at Cape Canaveral Air Station (CCAS) and Vandenberg Air Force Base (vAFB) produce exhaust ground clouds from the solid rocket boosters and liquid hypergolic fuels containing several toxic substances. In order to estimate the health effects that would be imposed upon the public by scheduled launches, range safety officials rely on the Rocket Exhaust Effluent Diffusion Model to predict ground level concentrations of these substances. A drawback to the REEDM is its underprediction of the initial ground clouds stabilization height. This underprediction causes an overprediction of the ground level toxic substance concentrations. This thesis focused on increasing the …

An Investigation Of Environmental Paradigms And Organizational Classifications, Marvin T. Ee Dec 1997

An Investigation Of Environmental Paradigms And Organizational Classifications, Marvin T. Ee

Theses and Dissertations

The extent of environmental management in organizations is largely determined by what paradigms are espoused with respect to maintaining both natural resources and raw materials. Environmental management paradigms possibly stem from whether an organization is private or public, producing a product or providing a service. However, no established methods exist for comparing organizations with regard to environmental management approaches and perspectives. The purpose of this thesis is to determine whether particular organizational classifications are linked to specific environmental management paradigms. This study incorporates several environmental management concepts to develop an analytical instrument for observing organizations. Environmental management paradigms provide a …

Optimal Orbit Insertion Strategies Using Combined High And Low Thrust Propulsion Systems, Darren W. Johnson Dec 1997

Optimal Orbit Insertion Strategies Using Combined High And Low Thrust Propulsion Systems, Darren W. Johnson

Theses and Dissertations

Low thrust electric propulsion systems are becoming sufficiently mature to consider their use as primary propulsion for orbital transfer in place of high thrust chemical systems. Instead of facing an either/or situation, it may be advantageous to use both types. This effort demonstrates a technique for finding orbital transfer strategies that use both high and low thrust propulsion systems and which result in optimal tradeoffs of the performance parameters cost of orbit insertion, total orbit transfer time, and available spacecraft mass at final orbit. These performance parameters are calculated as a function of the fraction of orbit transfer from Low …

Sinusoidal-Gaussian Beams In Complex Optical Systems, Lee W. Casperson, Dennis G. Hall, Anthony A. Tovar Dec 1997

Sinusoidal-Gaussian Beams In Complex Optical Systems, Lee W. Casperson, Dennis G. Hall, Anthony A. Tovar

Electrical and Computer Engineering Faculty Publications and Presentations

Sinusoidal-Gaussian beam solutions are derived for the propagation of electromagnetic waves in free space and in media having at most quadratic transverse variations of the index of refraction and the gain or loss. The resulting expressions are also valid for propagation through other real and complex lens elements and systems that can be represented in terms of complex beam matrices. The solutions are in the form of sinusoidal functions of complex argument times a conventional Gaussian beam factor. In the limit of large Gaussian beam size, the sine and cosine factors of the beams are dominant and reduce to the …

Non-Convex Costs And Capital Utilization: A Study Of Production Scheduling At Automobile Assembly Plants, George J. Hall Dec 1997

Non-Convex Costs And Capital Utilization: A Study Of Production Scheduling At Automobile Assembly Plants, George J. Hall

Cowles Foundation Discussion Papers

This paper studies how managers at automobile assembly plants organize production across time. Detailed data from eleven single-source automobile assembly plants display considerable cross-plant heterogeneity. At plants which make low- and medium-selling vehicles the capital stock often sits idle, production is more variable than sales, and weeklong shutdowns are often used to vary output. In contrast, at plants which make high-selling vehicles, the capital stock rarely sits idle, production is about as variable as sales, and over time — bit weeklong shutdowns — is most frequently used to vary output. To explain this difference in production scheduling, I formulate and …

Temperature-Dependence Studies Of Photorefractive Effect In A Low Glass-Transition-Temperature Polymer Composite, Bogdan Swedek, Ning Cheng, Yiping Cui, Jaroslaw W. Zieba, Jeffrey G. Winiarz, Paras N. Prasad Dec 1997

Temperature-Dependence Studies Of Photorefractive Effect In A Low Glass-Transition-Temperature Polymer Composite, Bogdan Swedek, Ning Cheng, Yiping Cui, Jaroslaw W. Zieba, Jeffrey G. Winiarz, Paras N. Prasad

Chemistry Faculty Research & Creative Works

The temperature dependence of the photorefractive effect in a polymer composite containing poly(9-vinycarbazole), tricresyl phosphate, buckminsterfullerene, and 4-(N,N-diethylamino)-β-nitrostyrene is presented. The photoconductive, electro-optic and photorefractive properties of the material have been studied in the temperature range of 22-61°C. An apparent increase of electro-optic modulation with temperature and its eventual saturation is observed. This behavior is attributed to the temperature activated orientational mobility of the second-order nonlinear chromophores. The polarization anisotropy between the p- and s-polarized readouts is consistent with what would be expected on the basis of directly measured effective electro-optic coefficients. By correlating the electro-optic value with the diffraction …
