The Effect Of The Galactic Spheroid On Globular Cluster Evolution, C Murali, Md Weinberg

Astronomy Department Faculty Publication Series

We study the combined effects of relaxation, tidal heating and binary heating on globular cluster evolution, exploring the physical consequences of external effects and examining evolutionary trends in the MilkyWay population. Our analysis demonstrates that heating on circular and low-eccentricity orbits can dominate cluster evolution. The results also predict rapid evolution on eccentric orbits either due to strong relaxation caused by the high densities needed for tidal limitation or due to efficient bulge shocking of low density clusters. The combination of effects leads to strong evolution of the population as a whole. For example, within the solar circle, tidally-limited 105M⊙ …

Globular Cluster Evolution In M87 And Fundamental Plane Ellipticals, C Murali, Md Weinberg

Astronomy Department Faculty Publication Series

The globular cluster population in M87 has decreased measurably through dynamical evolution caused by relaxation, binary heating and time-dependent tidal perturbation. For fundamental plane ellipticals in general, cluster populations evolve more rapidly in smaller galaxies because of the higher mass density. A simple evolutionary model reproduces the observed trend in specific frequency with luminosity for an initially constant relationship. Fits of theoretically evolved populations to M87 cluster data from McLaughlin et al. (1994) show the following: 1) dynamical effects drive evolution in the initial mass and space distributions and can account for the large core in the spatial profile as …

A Cuban Convent In The Age Of Enlightened Reform: The Observant Franciscan Community Of Santa Clara Of Havana, 1768-1808., John James Clune Jr

LSU Historical Dissertations and Theses

The reform of Mexican convents in the late eighteenth and early nineteenth century generally has been shown to have been ineffective. I suggest that reform at the Observant Franciscan community of Santa Clara of Havana achieved much better results. While conventual reform in Cuba did not attain perfection, it followed the pattern of administrative, economic and military reform in that it was more effective on the island than it was elsewhere in the Spanish empire. The success of conventual reform in Havana must be attributed to the diligence of the Spanish Crown. Whereas the reform of convents in Mexico became …

An Analysis Of Medium Of Exchange In Takeovers., Yuan-Shing Liao

LSU Historical Dissertations and Theses

This dissertation provides a detailed analysis of the medium of exchange in corporate takeovers. Previous theoretical works and empirical evidence suggest three distinct (but not necessarily mutually exclusive) elements of information asymmetry: the bidder's value, the target's value, and the synergy from a takeover. Chapter two of this dissertation integrates the theory of financial intermediation into the research of the medium of exchange in takeovers. The research question is how the bidders with favorable information employ financial intermediaries, such as accounting firms, investment banks, and commercial banks, to reduce the market's unfavorable reaction to announcements of equity-financed takeovers. Chapter three …

The Third Way: A Study Of Economic Justice In The Writings Of Karol Wojtyla (Pope John Paul Ii)., Woodard King Mott Jr

LSU Historical Dissertations and Theses

Pope John Paul II, born Karol Wojtyla, has written extensively about the human person and how that person acts in the world. Beginning with Wojtyla's doctoral dissertation presented at the Pontifical University of St. Thomas Aquinas on the Catholic mystic St. John of the Cross and continuing through the most recent best seller, Crossing the Threshold of Hope, Christian personalism has pervaded Wojtyla's writings, encyclicals, and public utterances. Wojtyla's perspective on economic justice, as shaped by his Christian personalism, is the subject of this dissertation. A systematic investigation of Wojtyla's theory of economic justice reveals a third way of economic …

Student Achievement, Parental Effort And Schooling, Andrew James Houtenville

Doctoral Dissertations

When evaluating public education programs that are aimed at improving student achievement, it is often assumed that a child's family background is an exogenous factor, albeit an important factor. However, parental decisions may be influenced by such programs. It is the assertion of Becker and Tomes (1976) that distortions in parental behavior (time allocation) may be one of the reasons that compensatory education fails to improve student achievement. In short, parents reduce their own effort when school services (schooling) is increased. However, theoretically parental responses are ambiguous; parental effort can increase or decrease in response to increased schooling. This dissertation …

Psychosocial And Sociostructural Determinants Of Mastery: The Context Of Age And Disability, Scott David Schieman

Doctoral Dissertations

The "active" and "potent" self has held a special interest to philosophers, psychologists, and sociologists since the inception of those disciplines. The present research uses sociological perspectives on social comparison and reference group theory to provide a framework for understanding the various dimensions of self-process in the context of age and disability. Specifically, this research examines associations between age, disability, and social status indicators as they impress upon personal agency or mastery.

This study uses secondary data that includes respondents aged 18 and over who resided in any of ten counties in Southwestern Ontario and were part of a two-wave …

Numerical Analysis For Blood Distribution In Complete Flow Cross-Section Microvascular Networks, Jewen Xiao

Doctoral Dissertations

As the blood flows through a bifurcation, the axisymmetric red blood cell concentration profile is skewed by plasma skimming. In the downstream segment of the bifurcation the concentration profile of red blood cells recovers symmetry by the red blood cell dispersion process.

In this study, the concentration convective equation, which models the red blood cell dispersion process, is solved with the method of finite differences in cylindrical coordinates. In the computation, a shear-induced diffusivity coefficient is used. The computed hematocrit ratios at the second bifurcation are compared with in vitro experimental data obtained from 50 $\mu$m serial trees with two …

The Female Coach In The World Of Collegiate Sport: Accommodation And Resistance To The Dominant Sport Culture, Nita Marie Lamborghini

Doctoral Dissertations

This research explores the nature and meaning of collegiate coaching as an occupation for women and the extent to which women coaches accommodate to and resist the dominant sport culture. This study includes a brief historical analysis of the roots of coaching as an occupation for women and the emergence and nature of the "female model" of sport. To further explore the nature and meaning of coaching and the extent of accommodation and resistance to the dominant sport culture, forty-six (46) in-depth interviews were conducted with women collegiate coaches currently employed at an NCAA affiliated institution. A brief survey and …

This Is Gonna Hurt Like Hell: A Pentecostal Student Enters The Academy, Stephen R. Barrett

Doctoral Dissertations

The little that has been written about expressions of religious experience in the field of Composition Studies focuses on the many ways religious belief places its adherents at a disadvantage in writing classrooms. We discuss in our journals and staffrooms only those religious conservatives who are most expressive of their beliefs. Many others sit in silence during discussions that may reveal anything of their beliefs, fearing to offend teachers and peers or to expose themselves to offenses from others. Unfortunately, these silent students contribute little or nothing to our understanding of the abilities of faith-centered students. Many are writing with …

Public Poetry, Memory, And The Historical Present: 1660-1745, Paul H. Mccallum

Doctoral Dissertations

"Public Poetry, Memory, and the Historical Present: 1660-1745" examines the role public poetry played in the fashioning of social memory during the so-called Augustan age of English literature; further, it traces in the rise and decline of public poetry during this period the emergence and subsequent estrangement of two distinctive modes of public memory: one highly emblematic and allusive in nature, fostering and indeed dependent upon a well-endowed collective sense of historical and literary tradition; the other far more literal and individualistic, fashioning social memory of the historical present--the present moment set against the backdrop of historical consciousness--by encouraging a …

Unruly Acts: An Inquiry Into The Art Of Letter Writing, Anne Righton Malone

Doctoral Dissertations

Although professors of ancient art of letter writing were among the most revered in medieval universities, instruction in this "gentle art" as Virginia Woolf once described it, is currently relegated to etiquette manuals and elementary school textbooks. And for most composition instructors and rhetoricians, that is where it should stay. Most twentieth century rhetoricians portray the medieval genre of letter writing as the product of a dark period in the history of rhetoric, passing it by in a quick move from the sermons of Saint Augustine to the classically grounded rhetoric of Peter Ramus.

During the nineteenth century, training in …

A Place In Town: Women Producing Cultural Stratification, Carrie Lynn Yodanis

Doctoral Dissertations

This study examines how women in a working class, fishing community select and present cultural orientations to distinguish themselves from other women and create stratification. Based on data gathered through eight months of participant observation and 44 in-depth interviews, the research shows that local women choose and then reinforce social identities that reflect the norms, values, lifestyles of either the working class town, the wealthy summer colony, or people from outside the community. They present their cultural orientations through their work ethics, leisure activities, consumption practices, and family values and expectations. By producing these identities, women create and establish a …

Mothers' Helpers: The Resources Of Female-Headed Families In A Working Class Community, Margaret Walsh

Doctoral Dissertations

This study examines why women form single parent households and how they maintain them in a rural community. In 1995 and 1996 I conducted in-depth interviews with 50 divorced, separated, and never-married mothers, and 10 interviews with people working in community service programs. My findings show how one group of women benefited from early financial investments from their own steadily employed parents who owned their home and raised a large family. These "strong" families are headed by women who finished high school and had work experience before getting pregnant. Although many of them gave birth out of wedlock, they had …

Moved By The Spirit: Protestant Diffusion And Church Location In Central America, With A Case Study From Southwestern Honduras., Terri Shawn Mitchell

LSU Historical Dissertations and Theses

This dissertation traces the evolution of Protestant missions in Central America from the colonial period to the present, focusing on the agents, direction, and methods of Protestant diffusion as well as the changing criteria for site selection. Chapters are arranged chronologically and progress from the macro-scale, Central America, to the micro-scale, six towns in southwestern Honduras (La Esperanza, Intibuca, Yamaranguila, San Juan, Erandique and Gracias). The chapters dealing with Central America outline when and where different mission boards have worked, as well as the geographical, economic, political and theological considerations driving site selection. The focus then narrows to patterns of …

Evolution Of The Galactic Globular Cluster System, C Murali, Md Weinberg

Astronomy Department Faculty Publication Series

We study the dynamical evolution of disk and halo globular clusters in the Milky Way using a series of Fokker-Planck calculations combined with parametric statistical models. Our sample of 113 clusters with velocity data is predicted to descend from an initial population of 250 clusters, implying more than a factor of two decrease in population size due to evolution. Approximately 200 of these clusters are in a halo component and 50 in a disk component. The estimated initial halo population follows a coreless R−3.38 density profile in good agreement with current estimates for the distribution of halo field stars. The …

Boris Yeltsin's Ascent To Power: Personae And The Rhetoric Of Revolution., Matthew Thomas Althouse

LSU Historical Dissertations and Theses

This study is an examination of the rhetorical strategies utilized by Boris Yeltsin during his rise to prominence and his role in the second Russian revolution. By borrowing concepts from the study of revolutions in science, the author contends that Yeltsin used three distinct rhetorical personae, or modes of public presentation, to forward his discourse between 1985 and 1991. These personae include the revolutionary, the conciliatory, and the conservative. With this critical vocabulary, the author argues that Yeltsin's successes and failures hinged on his fitting use of rhetorical personae in relation to four exigencies during the late-Soviet era: the evolution …

Technical Training Program Evaluation: Present Practices In United States' Business And Industry., Skip Twitchell

LSU Historical Dissertations and Theses

There is a lack of information on training evaluation. For those studies addressing the amount of evaluation that occurs and in which samples can be identified, the samples are non-random. There have been very few reports on the methods used for evaluation or the reasons why there is so little evaluation. This study used a random sample selected from members of the ASTD professional practice area titled, Technical and Skills Trainers. It can be argued that this is an informed sample involved in a training area that produces objective outcomes and should produce a favorable picture of training evaluation. Questions …

The Development Of A New Deal Land Policy: Fergus County, Montana (1900-1945)., Melissa Gilbert Wiedenfeld

LSU Historical Dissertations and Theses

Encouraged by the Enlarged Homestead Act, higher than average rainfall, and various boosters, thousands of Americans homesteaded in Montana and the northern Great Plains during the 1910s. The agricultural economy boomed during World War I, but the post-war contraction during the 1920s, coupled with drought, caused serious economic problems for farmers. In response to the problems in the agricultural economy, a Land Utilization movement emerged, led by agricultural economists such as Lewis C. Gray. Land utilizationists believed that a readjustment of land use would correct the problems in the agricultural economy. Toward that end they sought changes in federal land …

Nature And The Divine: Classical Greek Philosophy And The Political In The Thought Of Leo Strauss And Eric Voegelin., Todd Eric Myers

LSU Historical Dissertations and Theses

The following work is an attempt to clarify the relationship of two of the most significant political thinkers of the later part of the twentieth century. Previous scholarship on the relationship between Leo Strauss and Eric Voegelin has focused on the two men's different interpretations of the religious traditions of Judaism and Christianity. In this work, we explore the two men's presentations of classical Greek philosophy to illuminate how their differing readings of the classics come to similar conclusions regarding the nature and limits of the political. Our investigation probes how Strauss's treatment of philosophy as being slightly more comic …
