Forest Landscape Dynamics: a Semi-Markov Modeling Approach
A transition model (MOSAIC) is used to describe forest dynamics at the landscape scale. The model uses a semi-Markov framework by considering transition probabilities and Erlang distributed holding times in each transition. Parameters for the transition model are derived from a gap model (ZELIG). This procedure ensures conceptual consistency of the landscape model with the fine scale ecological detail represented by the forest gap model. Spatial heterogeneity in the transition model is driven by maps of terrain with characteristics contained in a Geographic Information System (GIS) database. The results of the transition model simulations, percent cover forest type maps, are exported to grid-maps in the GIS. These cover type maps can be classified and used to describe forest dynamics using landscape statistics metrics. The linkage model-GIS enhances the transition model spatial analytical capabilities. A parameterization algorithm was developed that takes as input gap model tracer files which contain the percent occupation of each cover type through time. As output, the algorithm produces a file that contains the parameter values needed for MOSAIC for each one of the possible transitions. Parameters for the holding time distribution were found by calculating an empirical estimate of the cumulative probability function and using a …

Southern Genre Painting and Illustration from 1830 to 1890
The purpose of this thesis is to give a concise view of stylistic, iconographical, and iconological trends in Southern genre paintings and illustrations between 1830 and 1890 by native Southern artists and artists who lived at least ten years in the South. Exploration of artworks was accomplished by compiling as many artworks as possible per decade, separating each decade by dominant trends in subject matter, and researching to determine political and/or social implications associated with and affecting each image. Historical documents and the findings of other scholars revealed that many artworks carried political overtones reflecting the dominant thought of the white ruling class during the period while the significance and interpretation of other artworks was achieved by studying dominant personal beliefs and social practices.

A Structural Equation Analysis of Intergenerational Differences in Attitudes toward Individual Modernity in the United Arab Emirates: Implications for Cross-Cultural Research
It has been widely believed that modernity is a byproduct of a nuclear family system, a highly urbanized society, and a secular way of life. As such, developing countries are characterized as modern insofar as their social and cultural structures are able to correspond to these criteria. To examine the validity of these propositions, data on two randomly-selected generations--daughters and mothers in the United Arab Emirates--were generated.

Mail Order Music: the Hinners Organ Company in the Dakotas, 1879-1936
Founded in 1879 by John L. Hinners, the Hinners Organ Company developed a number of stock models of small mechanical-action instruments that were advertised throughout the Midwest. Operating without outside salesmen, the company was one of the first to conduct all of its affairs by mail, including the financial arrangements, selection of the basic design, and custom alterations where required. Buyers first met a company representative when he arrived by train to set up the crated instrument that had been shipped ahead of him. Tracker organs with hand-operated bellows were easily repaired by local craftsmen, and were suited to an area that, for the most part, lacked electricity. In all, the company constructed nearly three thousand pipe organs during its sixty years of operation. Rapid decline of the firm began in the decade prior to 1936 during which the company sold fewer than one hundred instruments, and closed in that year when John's son Arthur found himself without sufficient financial resources to weather the lengthy depression. The studies of the original-condition Hinners organs in the Dakotas include extensive photographs and measurements, and provide an excellent cross section of the smaller instruments produced by the company. They are loud, excellently crafted, …

Systematics of the Stonefly Tribe Suwalliini Surdick and Behavioral Studies of Selected Species in the Stonefly Families Chloroperlidae and Perlidae
The purpose of this study is to revise the genus Suwallia and to evaluate the potential taxonomic importance of adeagal and other genitalic characters, adult pigment patterns and egg characters. The revision concentrates on western North American species while providing coverage of all species, except Suwallia asiatica Zhiltzova and Lavanidova where only presumed females have been available for study. Communication and mate locating behaviors in adult stoneflies are critical for life cycle completion and species perpetuation. Drumming signals are known for numerous species of Plecoptera, but mate searching patterns and specifically, if or how vibrational communication is utilized for locating mates are virtually unknown for all stonefly species. I conducted field or laboratory studies of three species to elucidate mate searching patterns and how vibrational communication is used for locating mates. The species studied included a bushtopper, Suwallia pallidula (Banks); a ground scrambler, Claassenia sabulosa (Banks); and treetopper, Perlinella drymo (Newman). The "fly-tremulate-search". "rock to rock" and "fly-drum-search" search patterns exhibited by these species are described, as well as how vibrational communication is used for mate finding. Vibrational signal production by tremulation is reported for the first time in Suwallia, and for only the second time Plecoptera.

Critical Factors in Successful Texas Middle Schools 1993-1995
An examination of the characteristics of Texas middle schools has been conducted with the objective of developing a planning tool for middle staffs. This success is measured by the Academic Excellence Indicator System (AEIS), whose rating scale has three components: campus scores on the Texas Assessment of Basic Skills (TAAS), campus attendance percentages, and campus dropout rates. TAAS scores and attendance rates have been the focus of this study. Two years of data were examined separately for research question. Principal component analysis reduced the number of indicators in both years' data to 20 factors/ Each of these factors received a designated based on the characteristics that the component indicators had in common. A multiple regression analysis was performed on these factors to determine the influence each had on the campus TAAS scores and attendance. The unpredictability of human subjects requires an additional step in this study to achieve valid conclusions. A comparison of the two years' results is made to discover attendance, gifted and talented programs, and teacher gender were the strongest overall positive influences on student achievement. Campus demographics, retention, and ESL/bilingual programs have the strongest association with low student achievement.

Factors Influencing Freshmen Students' College Choice at the University of North Texas: a Focus Group Study
This study focused on factors that may influence freshmen students when choosing their colleges, specifically those who attend metropolitan universities such as the University of North Texas. In addition to identifying major characteristics of the institution that attract students, it also explored the sources of information that students considered important when making their choice about where to attend college. The primary instrument for gathering the data was focus groups. These informal, small groups provided a format for in-depth discussion and probing questioning about the needs, wants and influential factors driving freshmen college choice. Ten focus groups were held with between six and ten students in a specially designed room on the campus of the University of North Texas. A professional moderator was employed and sessions were observed via a two-way mirror and tape recorded for later transcription. The major questions addressed in the focus groups included: What factors influenced students the most to attend the University of North Texas? What did they consider the level of friendliness on campus? And how did the marketing materials that the university distributed impact their decision to attend? The study found that the factors that most influenced freshmen to attend the University of North …
