The Effect Of Socioeconomic Status On Year-To-Year Persistence Of First-Generation And Continuing Generation Students At Two-Year And Four-Year Institutions: Developing A Conceptual Model, Jim S. Settle

Dissertations

Estimating the persistence of first-time students from the first year to the second year of college is a growing social and financial concern for postsecondary education. Studying how socioeconomic status affects year-to-year persistence may help to identify and assist those students who had socioeconomic profiles most likely to indicate challenges to year-to-year persistence.

This study used data from the Beginning Postsecondary Students Longitudinal Study (BPS:96/98). BPS is a nationally representative survey designed to provide additional information about the patterns of educational attainment and persistence for a subset of the more than 51,000 students included in the NPSAS:96 survey. This study …

An Empirical Study Of Fiscal Decentralization Of Local Governments In China, Jianfeng Wang

Dissertations

The world is experiencing dramatic fiscal reconstruction in the socialist and (former) socialist countries and of continuing and fascinating evolution of government structure elsewhere. Being one of the fastest growing economies over the past nearly three decades, China seems deeply embracing this global mantra of power devolution in her effort to energize local economy that was suffocated in the highly constricted state-planning system. The literature of the Chinese central-local studies suggests that fiscal decentralization from the central government to provincial governments is a key institutional factor to explain Chinese economic success. However, the literature misses various lower levels of government …

Performance Evaluation Models For Strategic Decision-Making: Towards A Hybrid Model, Geraldina Villalobos Quezada

Dissertations

Performance management systems serve strategic, administrative, and developmental purposes; therefore, their role in an organization cannot be overestimated. As a function of this strategic role, different evaluation models have been developed and implemented by organizations: BSC, CIPP, TQM, Six Sigma, and AOP.

Following a review of current evaluation theory and practice models that focus on improving strategic decision-making in organizations, four research questions were developed that sought to identify the interrelationships, evaluation components, evaluation indicators, data collected to support the evaluation,evaluation implementation protocols, quantitative and qualitative analyses, outcomes, and critical factors of the BSC and CIPP models.

A multiple case …

Hacks, Cracks, And Crime: An Examination Of The Subculture And Social Organization Of Computer Hackers, Thomas Jeffrey Holt

Dissertations

This dissertation examines both the subculture and social organization practices of computer hackers. The concept of normative orders (Herbert, 1998: 347) is used to explore hacker subculture in different contexts. To assess hacker social organization, I use Best and Luckenbill¿s (1994) framework of organizational sophistication as well as measures from Decker et al. (1998). The relationships between subculture, social organization, and behavior are explored as well. I collected three qualitative data sets to explore these issues, including posts from six on-line hacker discussion forums, in-depth interviews with active hackers, and field observations at the Defcon 12 hacker convention. These data …

The Lost Journals Of Sylvia Plath, Kimberly Dawn Knutsen

Dissertations

Sylvia Plath is one of the few authors who has been posthumously awarded the Pulitzer Prize. Plath's exceptional literary career is not limited with that. When twentieth-century literary history is examined, it becomes patent that no writer has created such an enormous impact as Sylvia Plath. Furthermore, no writer or poet has been as misunderstood as in the case of Plath. In addition, no writer or poet has been labeled often as "schizophrenic" or "mad" by scholars or researchers who do not have the slightest education in psychology or psychopathology. Therefore, the works written on Plath, or the studies that …

The Politics Of Neighborhood Governance: Understanding China’S State-Society Relations Through An Examination Of The Residents Committee, Jianfeng Wang

Dissertations

For the nearly three decades of coexistence between economic liberalization and political authoritarianism, China remains as an anomaly to the liberal mantraof our time. This project explores a segment of the China Paradox, the state-society interaction channeled by the Residents Committee. Being the largest urban neighborhood organization, the committee deserves study because of its controversial status interlaid between ordinary residents it claims to represent and the authoritarian state. The committee enters the discourse as a directly congruent example of the same paradox that the whole China displays, when it is endowed with important, yet tension-changed statutory functions ranging from social …

Analysis Of Group Differences And Predictors Of Hooper Visual Organization Test Scores, Michael R. Devries

Dissertations

The Hooper Visual Organization Test (VOT) is described in the manual as a screening instrument that measures the ability to organize visual stimuli (Hooper, 1983). The VOT is identified as being particularly sensitive to neurological impairment. Studies to determine the criterion and construct validity of the VOT have examined its usefulness in distinguishing between individuals with neurological impairment from those with other disorders. Few studies have included samples from normal, psychiatrically impaired, and neurologically impaired populations in determining the VOT's usefulness in identifying neurologically impaired individuals. Furthermore, as neuropsychology has moved away from the understanding of neurological impairment as a …

Willa Cather: The Letters And Novels Of A Romantic Modernist, Lisa Bouma Garvelink

Dissertations

Willa Cather believed the primary goal of art was to simplify, but she never believed the world to be a simple place. Her letters reveal abundant conflicted feelings about her own place in the world, while also revealing a concomitant determination to succeed at any cost. From O Pioneers! (1913) to Sapphira andthe Slave Girl (1940), her novels vary vastly, evidencing a complex dialectic between romantic absolutes and modernist uncertainties. Even in the novelsmost critics would see as notably romantic--specifically her earlier works--the modernist temperament and techniques create recognizable tension. Just as significantly, in her later, darker novels the romantic …

Starlight Drive, William R. Reynolds Jr.

Dissertations

Starlight Drive is a book-length manuscript of poems that reflects my abiding interest in how poetry can use the fiction writer's tools, such as characterization and setting, without sacrificing the beauty of the lyric. Like Rodney Jones, I write about my north Alabama childhood filtered through the lens of my adult life here in the Midwest. My field of perception does not begin in a cotton field like Jones', but on a cul-de-sac in a middle-class neighborhood of Huntsville, where my father was an engineer for NASA. The poems in my manuscript show my protagonist moving through a landscape peopled …
