Critical Study Of John Rawls’ Theory Of Justice, Jae-Wan Chung

Masters Theses

In discussing John Rawls' theory of justice , my main concern is to examine his theory, especially in difference principle, and to criticize the principle. The difference principle is that without improving the conditions of those who are worst off, the advantages of all those better off should not be permitted. The principle has some problems.

First, the principle is against our common judgment. There is no reason that we choose the principle under "original position," and the principle brings about a result to disregard others' important advantages for the least favored's profits. Secondly, according to Robert Nozick's entitlement theory, …

The Effects Of Non-Uniform Blade Geometries On Cascade And Turbine Stage Performance, Hiroyuki Maeda

Masters Theses

It is known that in-service turbomachinery blades do not have uniform shapes. There are small differences due to blade erosion, manufacturing tolerances, or faulty installation. These differences can be in the size, shape, or relative angles of the blade. In an effort to predict losses resulting from changes in blade thickness and/or blade angles, a two-part investigation has been conducted. A two-dimensional unsteady Navier-Stokes flow analysis has been used to perform numerical experiments.

First, simulations were performed for an isolated cascade. One of the two stators was scaled and/or rotated. Results of the numerical simulations show that increasing the blade …

The Photonic Band Structure Of Dielectric Systems With A Frequency Dependent Dielectric Function, Jiezhou Liu

Masters Theses

The concepts of band theory for electrons can be employed to describe the behavior of electromagnetic waves propagaiting in periodic dielectric structures with a frequency independent dielectric function. These periodic structures can produce photonic band gaps in which the propagation of electromagnetic waves is strictly prohibited. The introduction of a frequency dependent dielectric function in such systems gives rise to strong changes of the photonic bands in the neighborhood of the frequency resonance of the dielectric function.

In my thesis, the photonic band structure of a dielectric system with a frequency dependent dielectric function which undergoes a dielectric resonance will …

The Encirclement At Cherkassy-Korsun: An Assessment Of The Winners And Losers, Joseph Kent Lutes

Masters Theses

During the winter of 1944, two Russian armies encircled two German corps on the Dnieper River. The Germans managed to break out of the encirclement after an attempt to relieve them failed. The battle lasted only three weeks, but cost both sides greatly. Both sides carried out a successful airlift to keep their troops in action. The Germans carried out a brilliant campaign, while the Russians demonstrated that they still needed to perfect their encirclement doctrine and their propaganda.

Each side was hindered by its leaders. Hitler forced the Germans to hold ground, while Stalin forced his generals to fight …

Consanguinitas Et Ius Sanguinis: Kinship Calculation And Medieval Marriage, Sandra Masters

Masters Theses

Consanguinity, or blood-relatedness, was one of the most important criteria which determined the formation of marriage in the medieval era. Unfortunately, there is no comprehensive study in English which describes the development of consanguinity prohibitions and which explains fully the types of kinship calculation used as a part of the restrictions which developed. In order to fill this void, my goal in this thesis has been to offer a well-researched, comprehensive study of this topic.

I have examined the studies completed by other researchers and combined any pertinent information from those sources with my own research on medieval attitudes and …

An Experimental Apparatus For Studying Double Differential Scattering By Low-Energy Multiply Charged Ions From Atomic Targets, Meenatchi S. Gopinathan

Masters Theses

A new differential energy-gain spectrometer with a movable parallel-plate electrostatic energy analyzer has been constructed and tested for the study of double differential (in energy and angle) cross sections for state-selective electron capture processes in collisions of low-energy multiply charged ions with atomic gases. The ion beam is produced by extracting recoil ions from a primary interaction region where these ions are generated in collisions between a neutral target gas and a fast fluorine beam from the WMU tandem Van de Graaff accelerator. An einzel lens is used to focus the ion beam extracted from the recoil-ion source into a …

An Evolutionary Approach To Allocating Tasks In Hard Real-Time Distributed Systems, Christian Lang

Masters Theses

In real-time systems, correctness not only depends on the result of the computation but also on the time at which this result is available. The violation of timing constraints in hard real-time systems can be critical to human life or environment. Therefore, the scheduling algorithm for distributed systems has to allocate tasks to processing nodes so that no timing constraints can be violated. In addition to timing constraints, tasks have precedence and fault-tolerance constraints.

Static scheduling allocates tasks to processing nodes before the tasks are executed. Static scheduling problems are known to be NP-hard [4]. Therefore, heuristic techniques are necessary …

Zambian Nurses And The Aids Crisis: Towards A Socio-Cultural Analysis Of Hiv/Aids, Alicia Worley

Masters Theses

This study addresses the need for AIDS research that goes beyond quantitative in formation to deal with the complexities of local context. Sociocultural analyses have been frequently lost in a sea of research that is rooted in a biomedical/quantitative paradigm. As a result of this, issues of political economy, culture, and human agency are often handled at best, tangentially-this to the detriment of prevention and control programs. This study underscores the factors involved in the spread of HIV that lie outside the realm of physiology and medical "fact." The perception and responses of Zambian nurses at a governmental training hospital …

Estrogen Induced Eosinophil Migration Into The August Rat Uterus Is Associated With Intercellular Adhesion Molecule Expression, Daniel R. Orcutt

Masters Theses

Estrogen causes an influx of eosinophils into the uterus in female rats. The diapedesis of eosinophils out of the vasculature has also been observed in allergic reactions, parasitic infections, and atopic dermatitis, and has been associated with cellular adhesion molecules (CAMs). Antibody blocking studies against ICAM-1/ LFA-1 and VCAM-1/VLA-4 have suggested that both ligand/receptor sets of CAMs are involved in the selective recruitment of eosinophils out of the vasculature. ICAM- 1 is expressed on the vascular endothelium and decreases in expression when IL-4 is introduced. VLA-4 is present on eosinophils and is suspected to allow selective migration of eosinophils out …

Wintertime Observations On Pig (Sus Scrofa) Decomposition, David Glynn Mcbride

Masters Theses

Detailed knowledge of the behavior of insects and other arthropods associated with decomposing remains is essential to estimate the time since death. To date, many studies have been conducted on human and animal decomposition rates in warm and/or humid climates, but little is known about decomposition rates in a northern wintertime environment. This study was undertaken to document the progression of decay and arthropod activity under these conditions and provide data that can be utilized for estimating time since death in such climates.

Six stillborn pigs (Sus scrofa Linnaeus) were placed in cages in a woodlot near Western Michigan …
