Occupational Patterns Of Three Generations Of Taishan Chinese : A Reconsideration Of Middleman Minority Theory, Wei Wei Lou
Occupational Patterns Of Three Generations Of Taishan Chinese : A Reconsideration Of Middleman Minority Theory, Wei Wei Lou
Dissertations and Theses
Middleman minority theory explains why certain minorities in America have made impressive socioeconomic achievements. It is found that their occupational patterns play an important role in their socioeconomic success. Middleman minorities usually concentrate in certain occupations and dominate these occupations. The term "middleman" indicates that such ethnic minorities are functioning as middleman between lower and upper class, customer and producer in the host society.
The three preconditions through which middleman minorities get into these occupations are cultural, contextual and situational variables.
The cultural variables concern mainly the homeland of the minorities, the value system of their native culture, and the …

Mmpi And The Juvenile Sex Offender Russell Funk, Russell Funk
Mmpi And The Juvenile Sex Offender Russell Funk, Russell Funk
Dissertations and Theses
This study examined the effectiveness of the MMPI in identifying juvenile sex offenders. This study examined the hypothesis that previously identified subscales of the MMPI (i.e., Toobert et al. (1959) Pe scale and Dolan (1986) Ic scale) could be used in discriminating juvenile sex offenders (n=l 02) (and subgroups of juvenile sex offenders i.e., pedophiles n=79, and incest perpetrators n=41) from a control group of 40 juvenile offenders who had been adjudicated for non-sex related crimes. The study yielded results which indicate that the Pe subscale was not effective in discriminating pedophiles from non-pedophile sex offenders or from the control …

Two Dimensional And Three Dimensional Path Planning In Robotics, Hyun Suk Kim
Two Dimensional And Three Dimensional Path Planning In Robotics, Hyun Suk Kim
Dissertations and Theses
A methodology for 2D and 3D collision free path planning algorithm in a structured environment is presented. The isolated free convex areas are represented as a nodes in a graph, and a graph traversal strategy that dynamically allocates costs to graph path is used. Modification of the algorithm for small computational time and optimality is discussed. The 3D path planning is done in the three orthogonal two-dimensional projections of a 3D environment. Collision checking to increase the optimality for 3D paths is done in each of the three orthogonal two-dimensional subspaces.
A Contextualized Grammar Proficiency Test Using Informal Spoken English, Sally Wellenbrock Hinrich
A Contextualized Grammar Proficiency Test Using Informal Spoken English, Sally Wellenbrock Hinrich
Dissertations and Theses
Intensive college-level ESL programs typically focus on building students' academic skills in English. Yet many ESL students leave the intensive programs only to find that they cannot sufficiently comprehend conversations with native English-speaking classmates or understand freshman-level lectures. While the students frequently perceive the problem as relating to the rapid speech tempo used by native speakers, an integral part of the comprehension problem is the pervasive use of modified forms of English, commonly called reductions, contractions, and assimilations.
The present research investigates whether comprehension of certain modified forms of spoken informal English can be used to measure students' level of …
Off-Axis Multimode Light Beam Propagation In Tapered Lenslike Media Including Those With Spatial Gain Or Loss Variation, Anthony Alan Tovar
Off-Axis Multimode Light Beam Propagation In Tapered Lenslike Media Including Those With Spatial Gain Or Loss Variation, Anthony Alan Tovar
Dissertations and Theses
The propagation of light beams in inhomogeneous dielectric media is considered. The derivation begins with first principles and remains general enough to include off-axis asymmetric multimode input beams in tapered lenslike media with spatial variations of gain or loss. The tapering of lenslike media leads to a number of important applications. A parabolic taper is proposed as a model for a heated axially stretched fiber taper, and beams in such media are fully characterized. Other models are proposed by the concatenation of a parabola with other taper functions.
Syntactic Complexity, Error And The Holistic Evaluation Of Esl Student Essays, John S. Sparks

Rock Slope Stability Studies In Siskiyou National Forest, Greg Visconty
Rock Slope Stability Studies In Siskiyou National Forest, Greg Visconty
Dissertations and Theses
The line mapping method of Piteau and Martin (1977) was tested on two different rock type road cuts in the Siskiyou National Forest, and was found to be an efficient means of collecting geological data for rock slope stability analysis. The unbiased approach of this method calls for close scrutiny of the outcrops in question, covering more ground than other methods in less time. In turn, this close attention to every crack in the outcrop reveals more about the stability of the slope, and can reveal hidden hazards of rock fall.
The supportive systems for analyzing the data - stereonets …

Hyperbolic Soil Parameters For Granular Soils Derived From Pressuremeter Tests For Finite Element Programs, Dieter Neumann
Hyperbolic Soil Parameters For Granular Soils Derived From Pressuremeter Tests For Finite Element Programs, Dieter Neumann
Dissertations and Theses
In the discipline of geotechnical Engineering the majority of finite element program users is familiar with the hyperbolic soil model. The input parameters are commonly obtained from a series of triaxial tests. For cohesionless soils however, today's sampling techniques fail to provide undisturbed soil specimen. Furthermore, routine triaxial tests can not be carried out on soils with grains exceeding 10 - 15 mm in size.
Initial developments towards a link between high quality pressuremeter tests and the hyperbolic finite parameters element input are presented. Theoretical and empirical approaches are used to determine the entire set of and from pressuremeter tests. …

Development Of A Parametric Analysis Microcomputer Model For Evaluating The Thermodynamic Performance Of A Reciprocating Brayton Cycle Engine, Thomas Joseph White
Development Of A Parametric Analysis Microcomputer Model For Evaluating The Thermodynamic Performance Of A Reciprocating Brayton Cycle Engine, Thomas Joseph White
Dissertations and Theses
In this thesis, applicable data from research on IC engines have been adapted to PACE engine designs. Data from studies on heat transfer, friction, and pressure losses, in particular, have been used. Certain parameters which define operation and design characteristics appear to influence PACE engine performance very strongly. Some of the more critical parameters, notably friction and heat transfer coefficients, must be determined experimentally if accurate model results are to be expected. Pressure ratio, compressor RPM, and maximum combustor temperature, the independent operating parameters, also have a dramatic effect on engine performance. Other design or operating characteristics and working fluid …
The Differential Role Of The Ssi With Normal Preschool Children, Caroline Joy Semler
The Differential Role Of The Ssi With Normal Preschool Children, Caroline Joy Semler
Dissertations and Theses
The onset of stuttering usually occurs between two and six years which is the same time most children exhibit normal disfluencies often making it difficult to differentiate between normally disfluent children and incipient stutterers. Clinicians need information on the types and frequencies of disfluencies exhibited by normal preschool children in order to determine if a child is more likely to be an incipient stutterer or normally disfluent child. Some clinicians feel uncomfortable relying on past literature since there is a limited amount of information available and the studies have shown a considerable amount of variability in the types and frequencies …
The Effect Of Cold Acclimation On The Temperature Preference Of The Goldfish, Carassius Auratus, And The Brown Bullhead, Ictalurus Nebulosus, Alfred Lord
Dissertations and Theses
Two species of fish, Carassius auratus and Ictalurus nebulosus, were subjected to cold acclimation regimes. Acclimation temperatures were slowly lowered to 3°C, then held for a period of time. At various times during this regime, fish were taken out and allowed to spend time in a temperature gradient to determine their preferred temperatures. Carassius were left in the gradient just long enough to determine a measure of the acute temperature preference, while Ictalurus were left in the temperature gradient for longer periods of time to observe any changes that might occur as the fish adjusted to selected temperatures. In …
The Effects Of Test Result And Diagnosticity On Physicians’ Revisions Of Probability Of Disease In Medical Diagnosis, Ann Elizabeth Sinclair
The Effects Of Test Result And Diagnosticity On Physicians’ Revisions Of Probability Of Disease In Medical Diagnosis, Ann Elizabeth Sinclair
Dissertations and Theses
This study examined the effects of sensitivity, specificity and result of diagnostic tests on the uses which physicians make of those results. These were compared with the Bayesian model of probability adjustment, which is generally accepted for medical diagnosis. Ninety six active members of the Oregon Academy of Family Physicians were interviewed by telephone, using a case scenario describing a patient with a newly discovered breast lump. Subjects estimated prior probability of malignancy, based on history and physical findings, and then estimated posterior probability following results of a mammogram. Mammograms varied by result (positive or negative) and by high and …
The Influence Of Work Station Architecture On Work Perceptions And Work Behavior, Connie L. True
The Influence Of Work Station Architecture On Work Perceptions And Work Behavior, Connie L. True
Dissertations and Theses
A field study was conducted to find whether open office architecture is related to employees' perceptions of their jobs and their work groups, and to their behavior in and around their work stations. Fifty-two employees in the administrative division of a large manufacturing operation volunteered to participate by answering a questionnaire and allowing their work stations to be analyzed for levels of visual access and visual exposure, the two independent variables. Access and exposure, at first theorized to be independent and interacting functions, were found to be too highly correlated in this open office setting to test as originally planned. …

Disfluencies In Normal Three-Year-Old And Five-Year-Old Male Children, Pamela Paguia Christianson
Disfluencies In Normal Three-Year-Old And Five-Year-Old Male Children, Pamela Paguia Christianson
Dissertations and Theses
The purpose of this study was to compare the frequency of specific disfluencies in 3 year old and 5 year old normal male children in terms of part-word repetitions, word repetitions, phrase repetitions, interjections, revision-incomplete phrases, disrhythmic phonations and tense pauses. The disfluencies were observed while each child spontaneously interacted with an investigator in a clinical room. Two questions were addressed:
- Do three-year-old male children exhibit a higher overall frequency of disfluencies than five-year-old male children?
- Do three-year-old male children exhibit a greater frequency of certain disfluencies than five-year old male children?
Decrease In Selected Temperature After Intracranial Dopamine Injections In Goldfish, Hercules Theodore Panayiotides-Djaferis
Decrease In Selected Temperature After Intracranial Dopamine Injections In Goldfish, Hercules Theodore Panayiotides-Djaferis
Dissertations and Theses
Goldfish (Carassius auratus) (40-80g) were injected with dopamine into the forebrain to study the possible involvement of this amine in central temperature regulation in these fish. Dopamine caused a decrease in selected temperature after injection into the rostral nucleus preopticus periventricularis (NPP). This effect was dependent on the dose of dopamine administered. Doses of 25, 50, 100 and 250 ng were used, injected in a volume of 0.2μ1. Injections in regions adjacent to the NPP elicited hypothermic effects only at the higher dosages. These effects were not consistent. Injections in caudal regions of the NPP elicited no effect. …
Geomorphic Character, Age And Distribution Of Rock Glaciers In The Olympic Mountains, Washington, Steven Paul Welter
Geomorphic Character, Age And Distribution Of Rock Glaciers In The Olympic Mountains, Washington, Steven Paul Welter
Dissertations and Theses
Rock glaciers are tongue-shaped or lobate masses of rock debris which occur below cliffs and talus in many alpine regions. They are best developed in continental alpine climates where it is cold enough to preserve a core or matrix of ice within the rock mass but insufficiently snowy to produce true glaciers. Previous reports have identified and briefly described several rock glaciers in the Olympic Mountains, Washington, but no detailed integrative study has been made regarding the geomorphic character, age, and distribution of these features.
The purpose of this study is two-fold. First, surface sediment fabric analysis and relative and …
Friendship Between Women: The Influence Of Incest, Laurie Lockert
Friendship Between Women: The Influence Of Incest, Laurie Lockert
Dissertations and Theses
This study focused on the mother/daughter relationship in father/daughter incest and how that relationship influences women's friendships with other women. Many researchers have concluded that females who were sexually abused by male authority figures, i.e., father, step-father, grandfather, older brother, minister, babysitter, will have impaired relationships with men. Clinicians surmise that the enormous betrayal of trust involved in the incest leads the child to generalize from her experience with one male to all males. Victims express feelings of distrust, fear of intimacy, and fear of personal expression in all male/female relationships. Studies suggest that in families where father/daughter incest has …
Hugo Grotius And The Liberal Tradition, Karen Diane Csajko
Hugo Grotius And The Liberal Tradition, Karen Diane Csajko
Dissertations and Theses
One approach in contemporary international relations theory is the moralist position. Most moralists argue that obligations which an individual has toward the state and toward persons qua fellow citizens should not override the obligations which every individual has toward other persons qua members of humanity. Essential to a moralist approach is the idea that every individual shares some feature, such as rights, which is universal to all men and incontrovertible by any body. Many moralists base their theory upon the thought of Hugo Grotius, equating Grotius's thought with their own moralist approach.
This thesis argues that Grotius does not present …

The relative contribution of arteriovenous oxygen (A-V O2) difference to thermally-induced and activity-induced changes in metabolic rate (VO2) were delineated in the toad, B. marinus. In conjunction, the influence of rest and activity, temperature, and removal of the pericardial sac on separation efficiency (Es) in the anuran ventricle was determined by direct measurement of arterial and venous percent oxygen saturation (% saturation), using a microsampling technique.
El Sindicato De Las Costureras 19 De Septiembre: The Impact Of The 1985 Mexico City Earthquake On Social Process, Margaret Mccrea
El Sindicato De Las Costureras 19 De Septiembre: The Impact Of The 1985 Mexico City Earthquake On Social Process, Margaret Mccrea
Dissertations and Theses
The paper traces out the relationships between three sets of actors--workers, factory owners, and government--before, during and after the 1985 Mexico City earthquake, and places those relationships in the broader context of Mexico's political and economic development, as well as the spatial structure of Mexico City and the garment district. The paper concludes that although victims respond to the crisis by attempting to restore and repair previous social and physical conditions, as social theory predicts, disasters have different effects on different classes of people, who respond according to their needs, vulnerabilities, perceptions, values, and their socially prescribed powers. Where there …

Gun Running In Arabia: The Introduction Of Modern Arms To The Peninsula, 1880-1914, James W. Fiscus
Gun Running In Arabia: The Introduction Of Modern Arms To The Peninsula, 1880-1914, James W. Fiscus
Dissertations and Theses
Modern breech-loading rifles flooded into Arabia and the region around the Persian Gulf between 1880 and World War I. This work examines in detail, and analyzes, the introduction of modern arms to Arabia, the origin of those arms, the trade patterns by which they were moved, and the international and local political factors that affected the trade. The international arms trade was driven by three major factors. First, the rapid technological development of small arms in the nineteenth century fed the market, resulting in the availability of hundreds of thousands of obsolete military rifles for resale. Each time new rifles …
