Flow Near Submarine Canyons Driven By Constant Winds, Jun She, John M. Klinck

CCPO Publications

Circulation over coastal submarine canyons driven by constant upwelling or downwelling wind stress is simulated and analyzed with a primitive equation ocean model. Astoria Canyon, on the west coast of North America, is the focus of this study, and model results are consistent with most major features of mean canyon circulation observed in Astoria Canyon. Near-surface flow crosses over the canyon, while a closed cyclone occurs within the canyon. Upwelling prevails within the canyon and is larger than wind-driven upwelling along the adjacent shelf break. Water rises from depths reaching 300 m to the canyon rim and, subsequently, onto the …

Antidepressent Treatment For Depression: Total Charges And Therapy Duration, Deborah G. Dobrez, Catherine A. Melfi, Thomas W. Croghan, Thomas J. Kniesner, Robert L. Obenchain

Center for Policy Research

Background: The economic costs of depression are significant, both the direct medical costs of care and the indirect costs of lost productivity. Empirical studies of antidepressant costeffectiveness suggest that the use of selective serotonin reuptake inhibitors (SSRI) may be no more costly than tricyclic antidepressants (TCA), will improve tolerability, and is associated with longer therapy duration. However the success of depression care usually involves multiple factors, including source of care, type of care, and patient characteristics, in addition to drug choice. The cost-effective mix of antidepressant therapy components is unclear.

Aims of the Study: Our study evaluates cost and antidepressant-continuity …

Microsatellite Dna Diversity And Paternity Determination In A Captive Population Of Radiated Tortoises (Geochelone Radiata), Jennifer Leigh Mook

All Theses

In the present study, five microsatellite loci are used to examine genetic diversity and determine genetic similarities among 66 radiated tortoises (Geochelone radiata) located in ten different zoos and institutions in the United States. These tortoises, representatives of one of the world's most endangered species, were originally collected in Madagascar and are being used as founders in the development of an organized breeding program, the radiated tortoise Species Survival Plan (SSP). Parentage analysis was also conducted for 13 juvenile tortoises of uncertain parentage from two institutions. Founder tortoises demonstrated high levels of genetic diversity at the five loci …

Computer-Based Methods For Constructing Two-Level Fractional-Factorial Experimental Designs With A Requirement Set, Steven L. Forsythe

Theses and Dissertations

This dissertation developed four methodologies for computer-aided experimental design of two-level fractional factorial designs with requirement sets (DOE/RS). The requirement sets identify all the experimental factors and the appropriate interaction terms to be evaluated in the experiment. Taguchi graphs and similar manual methods provide techniques for solving the DOE/RS problem. Unfortunately, these methods are limited because they become difficult to use as the number of factors or interaction terms exceeds ten. This research showed that the DOE/RS problem belongs to a class of difficult-to-solve problems known as NP-Complete. It is the combinatorial nature of NP-Complete problems that causes them to …

Covalidation Of Dissimilarly Structured Models, Samuel A. Wright

Theses and Dissertations

A methodology is presented which allows comparison between models constructed under different modeling paradigms. Consider the following situation: Two models are constructed to study different aspects of the same system. One model simulates a fleet of aircraft moving a given combination of cargo and passengers from an onload point to an offload point. A second model is a linear programming model that optimizes the aircraft and route selection required for the same scenario. We develop a methodology to structure the comparison between large-scale models such as these. Models that compare favorably using this methodology are deemed covalid. Models that perform …

Subcutaneous Adipose Tissue Thickness Changes Cooling Time During Cryotherapy, Jeffrey W. Otte

All-Inclusive List of Electronic Theses and Dissertations

Context: Cryotherapy is often applied using a standard treatment time. Use of a standard treatment time fails to consider the insulating effect subculaneous adipose tissue has during cooling of underlying muscle. If differences in adipose lissuc thickness alter I he effects of cryotherapy, then a standard application time may not produce a slamlard clTcct for all patients. Objective: The purpose of this study was to examine the effects of subcutaneous adipose tissue on cooling time during cryothcrapy. Design: A 1 x 4 factorial design was used in this study. The independent variable was skin-fold thickness, 0-10mm, 1 l-20mm, 2 l-30mm, …

The Effects Of Eldercare Responsibilities On Employed Caregivers, Nancy Jean Mcenroe

Theses and Dissertations

The number of people in the older population will continue to grow as the decades progress. The most rapid increase expected would be between the years 2010 and 2030 when the “baby boom” generation reaches 65 years or older. By the year 2030, there will be about 70 million older persons, more than twice the number than for the year 1998.

More and more people will live long enough to experience multiple chronic illnesses, disability, and dependency; in addition there will be more relatives in their fifties and sixties who will be facing the concern and expense of caring for …

A Spatial Inquiry Of Infant Low Birthweight And Cancer Mortality In East Baton Rouge Parish, Louisiana, Esra Qzdenerol

LSU Historical Dissertations and Theses

Infant low birthweight rate in East Baton Rouge Parish is higher compared to the nation. Cancer is one of the most serious health problems in Louisiana. A few studies have indicated a relationship between the two health outcomes and their environment, but conclusions from these studies have not always been consistent. The spatial and temporal scales of the data and the methods used in these studies contribute to the inconsistent and uncertain results. The spatial patterns of infant low birthweight and cancer mortality in East Baton Rouge Parish from 1993 to 1996 and their relationships with environmental factors at three …

An Investigation Into The Effect Of Plate Hardness, And Surface Speed Differential On Flexographic Gear Marking, Wisit Wirojrungson

Theses

Gear marking is a print defect in flexography. It appears as a uniformly spaced pattern of lateral alternating dark and light bands along the web length corresponding to the distance between gear teeth. A comprehensive definition characterizes gear marking as a regular pattern attributable to metal burrs, nicks, debris, or other flaws that lead to unsmooth movement somewhere in the mechanical system of the press. Gear marking can be caused by a multitude of different factors. In most cases, gear marking results from more than one phenomenon. The objective of this study was to investigate some factors that were expected …

Long-Toed Salamanders In Harvested And Intact Douglas-Fir Forests Of Western Montana, George P. Naughton, Colin B. Henderson, Kerry R. Foresman, Rex L. Mcgraw Ii

Biological Sciences Faculty Publications

There is little known about how timber harvest practices have affected terrestrial amphibians in the northern Rocky Mountains. Especially lacking is information on the effects of revised harvest methods that fall within the framework of environmental or New Forestry. We estimated the relative abundance of a common forest amphibian, the long-toed salamander (Ambystoma macrodactylum) captured in pitfall arrays on intact, environmentally harvested, and overstory-removal harvested sites in mixed-conifer forests of western Montana. Pitfall data from 1994 through 1996 showed that previously logged sites contained significantly fewer long-toed salamanders regardless of harvest method used. The number of salamanders captured …

Final Report: Study Of Sympatric Moose And Elk In The Garnet Range Of Western Montana, 1997-2000, Milo Burcham, C. Les Marcum, Dave Mccleerey, Mike Thompson

Wildlife Biology Faculty Publications

Elk (Cervus elaphus) have been a major consideration in forest management in the western United States. Other ungulate species that are sympatric with elk, such as Shiras moose (Alces alces shirasi), have often received less management consideration. We studied a moose population in the Garnet Mountains of west-central Montana from 1997 to 2000, to learn more about moose habitat preferences. At the same time, we capitalized on elk data collected in a portion of the moose study area from 1993,...1996, so that moose and elk habitat use could be o compared. Logistic regression was used to model moose and elk …

The Relative Age Of The Thin And Thick Galactic Disks, Wilson M. Liu, Brian Chaboyer

Dartmouth Scholarship

We determine the relative ages of the open cluster NGC 188 and selected Hipparcos field stars by isochrone fitting and compare them to the age of the thick-disk globular cluster 47 Tuc. The best-fit age for NGC 188 was determined to be 6.5 ± 1.0 Gyr. The solar-metallicity Hipparcos field stars yielded a slightly older thin-disk age, 7.5 ± 0.7 Gyr. Two slightly metal-poor ([Fe/H] = -0.22) field stars whose kinematic and orbital parameters indicate that they are members of the thin disk were found to have an age of 9.7 ± 0.6 Gyr. The age for 47 Tuc was …

Worker's Compensation, H. Michael Bagley, Daniel C. Kniffen, Katherine D. Dixon, Marion Handley Martin

Mercer Law Review

For workers' compensation, the 1999-2000 survey period was largely notable for a number of legislative changes and for another year in which Georgia's appellate courts dealt with numerous cases interpreting the exclusive remedy provisions of the Workers' Compensation Act. As always, however, the appellate courts also decided numerous workers' compensation cases, with issues ranging from the "any evidence" rule to superior court judgments.

Additional legislative activity is possible in the coming year as a special commission appointed by Governor Barnes readies a report, due in April 2001, on proposed changes to the workers' compensation system.

A Genre Study Of Ralph Ellison’S Invisible Man, Marilyn Faye Garrett

Theses (Pre-2016)

This study tests the hypothesis that Ralph Ellison's novel, Invisible Man, employs eclectic techniques, and is therefore a complex genre. Accordingly, the assumptions which undergird this investigation embrace notions attendant to folklore, myth and comedy. Testing these assumptions, the study proceeds with the following objectives: (1) , ,to isolate and identify major characteristics found in three genre of the literary canon, and (2) to focus on Jacques Lacan's theory of psychoanalysis and its applicability to the narratology of the novel. Specifically, there are three distinct concepts which shape the study. These are (1) Ellison's use of the blues in his …

Residual Stress And Wear Resistance Of Composite Coatings Of Nickel/Gamma-Alumina, Khaled Abdulrahman Al-Ogab

Masters Theses

Nickel reinforced with nanoparticles of γ−Al₂O₃ have been successfully codeposited on 2024-T3 cold rolled aluminum alloy by electrodeposition with direct current. The effects of current density, particle concentration in the nickel sulfamate bath, air agitation, and coating time on Ni/γ−Al₂O₃ composite have been investigated. The residual stresses and wear resistance of the Ni/γ−Al₂O₃ composite have been measured using X-ray diffractometer and pin-on-disk techniques respectively. The residual stress and wear resistance behavior of the composite were compared with those of nickel-only deposits. An annealed ground nickel, which was mechanically removed from the …

Performance Comparison Of A Roundabout Versus Two-Way Stop Controlled (Twsc) Intersections, Deogratias Eustace

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

The superior safety record of modern roundabouts is well known in Western Europe, Australia and in most British-influenced countries around the world. The experience from a single modern roundabout installed in the City of Manhattan, Kansas, some three years ago, also shares the same experience. A major study of the performance of Manhattan, Kansas, modern roundabout was conducted at Kansas State University (KSU) and was co-sponsored by Mac-Blackwell National Rural Transportation Study Center, Kansas State University, and the City of Manhattan. The study examined three intersections, one modern roundabout and two Two-Way Stop Controlled (TWSC) intersections with similar traffic conditions. …

Job Stability And Wage Progression Patterns Among Early Tanf Leavers, Steven G. Anderson, Anthony P. Halter, George Julnes, Richard Schuldt

The Journal of Sociology & Social Welfare

This article reports on first-year employment experiences of a randomly selected sample of 213 Illinois TANF leavers. Aggregate employment levels were 70 percent at exit, and leavers typically generated earnings from a single full-time job. However, employment often was unstable, so that only about one-fourth of leavers had the same job both at exit and when interviewed 10-11 months later. Employment instability resulted from the marginal or temporary nature of many jobs, as well as employment barriers such as health problems and lack of day care. Average wage levels easily exceeded the minimum wage and grew during the first year …
