The Meaning Of Masculinity For Male Baccalaureate Nursing Program Graduates, Kenneth Tillman

LSU Doctoral Dissertations

Previous researchers have reported that societal definitions of masculinity may act as a barrier to men entering the nursing profession, and that men who do enter nursing may hold a different view of masculinity. The purpose of this study was to describe the meaning of masculinity for recent male baccalaureate nursing program graduates. In addition, the study explored how the participants’ perceived meaning of masculinity shaped or influenced their nursing education experiences, and in turn how their nursing education experiences may have shaped or influenced their perceived meaning of masculinity. A phenomenological research design was used to study eight male …

Distribution And Biogeography Of Central American Howling Monkeys (Alouatta Pigra And A. Palliata), Amrei Baumgarten

LSU Master's Theses

Central America has two howling monkey species: the widespread mantled howling monkey (Alouatta palliata) and the endemic and endangered black howling monkey (A. pigra) limited to southeastern Mexico, northern Guatemala and Belize. Studies that verify the distribution of these species are needed, especially in their contact zones where sympatry is reported. Their evolutionary history remains controversial. My study examines their distribution at a local scale in a potential contact zone in eastern Guatemala through direct observations and interviews and at a regional scale across the entire isthmus using data from museum specimen localities, study sites, historic records and field surveys. …

Tribological Aspects Of Journal Bearings Focusing On The Stribeck Curve, Xiaobin Lu

LSU Doctoral Dissertations

The dissertation focuses on the frictional characteristics of journal bearings as represented by the Stribeck curve. The behavior of lift-off speed and the factors that affect it are explored. An equation is proposed for predicting the lift-off speed. The comparison between the experimental results of oil- and grease-lubricated journal bearings with a mixed elastohydrodynamic lubrication model for line contacts is indicative of good agreement in the mixed lubrication regime. Efforts are made to modify the surface profile of bushing by putting dimples on its surface. Experimental results show that with proper dimensions of dimples, the friction performance of journal bearings …

New Programs In The Old Asylum: The Deinstitutionalization Of Long-Term Psychiatric Hospital Patients In Argentina, Erica Dillon

LSU Master's Theses

Large psychiatric hospitals with inpatients interned for decades are still the norm in Argentina, where deinstitutionalization and community-based mental health care is almost inexistent. This thesis focuses on some changes taking place in a centenary psychiatric hospital in Buenos Aires province: the externación of long-term psychiatric patients through new programs planned and run from inside the institution by health professionals compromised in making a change in the old asylum. Can long-term inpatients with serious mental illness such as schizophrenia leave the asylum and integrate in the society having a recovered life? Do the new externación programs make this possible? What …

Statistical analyses provided estimates of direct heterosis (h_i), cross heterosis (h_ij), maternal effects (m_i), line effects (l_i), reciprocal and specific reciprocal effects (r_ij and r**_ij), and general and specific combining abilities (GCA and S_ij). Analysis of genetic effects for ST indicated that FL …

Mothers Grimm And Other House Held Tales, Holly Kay Streekstra

LSU Master's Theses

Mothers Grimm and Other House Held Tales is a body of work that uses fairy tale archetypes and narrative traditions to comment upon tensions and conflicts in sexual self-understanding. This is achieved through a reflection on attitudes that women adopt regarding their own sexuality. Such a reflection is instigated through a presentation of prominent cultural archetypes that exist, no longer as received ideas, but as a bold and entertaining expression of how sex can change our attitude towards those ideas that we often take for granted. Through an assemblage of objects and video, this body of work evokes a domestic …

Lock'em Up And Throw Away The Key: Racial Attitudes And The Structural Determinants Of Support For Crime Policy Among White Americans, Amanda J. Abraham

The Other Side Of The Tracks: Railroads, Race, And The Performance Of Unity In Nineteenth-Century American Entertainment, Elissa Sartwell

LSU Doctoral Dissertations

Nineteenth-century Americans took great pride in the completion of the first transcontinental railroad in 1869. This pride was not solely grounded in the knowledge that a grand, technological feat had been accomplished. When placed in its historical context, the celebration surrounding the completion of the railroad suggests a clear and visible statement of unity following a bitter and divisive civil war. The transcontinental railroad of 1869 undeniably unified the States. But any railroad simultaneously unites and divides, for while the tracks serve to link distant locations, they also produce a literal and metaphorical division in the communities through which they …

Re-Examining The Subculture Of Violence In The South, Timothy Curt Hayes

LSU Doctoral Dissertations

The Southern region of the United States historically has a high rate of violent crime, especially homicide. This has led to a number of studies tackling the issue by relying on subcultural theory or by using structural correlates of crime to account for the South versus non-South difference in homicide. Macro level research has focused on pitting culture (usually measured by a dummy variable for South) against structural characteristics such as poverty and measures of income inequality, but suffers from a lack of direct cultural measures needed to successfully evaluate the subcultural thesis. Micro level research tends to focus on …

System Optimization For Realizing A Miniaturized Gas Chromatograph Sensor For Rapid Chemical Analysis, Abhinav Bhushan

LSU Doctoral Dissertations

Rapid and comprehensive on-site analysis of chemicals in applications ranging from industrial process control to homeland security is of significant importance to improve the environment and save human life. The need for sensors that are fast, reliable, and portable has never been greater. For the challenging task of on-site instrumentation, where power sources can be limited, shrinking the size of the device is the most effective way to conserve power. Although gas chromatography is a mature technique well suited for these applications, current instrumentation has deficiencies that limit its usage. Speed of analysis and non portability are severe hindrances to …

Retention And Transport Of Arsenic In Soils, Hua Zhang

LSU Doctoral Dissertations

Arsenic transport in soils and aquifers is highly dependent on the adsorption-desorption reactions in the solid phase. Results from our kinetic batch experiments indicated that adsorption of arsenate [As(V)] was highly nonlinear and strongly kinetic. Desorption of As(V) were hysteretic in nature and a significant amount of As(V) was irreversibly adsorbed on all soils. Results from column experiments indicated strong As(V) retardation followed by slow release or extensive tailing of the breakthrough curves (BTCs). Sharp decrease in As(V) concentration during flow interruption verified the extensive non-equilibrium condition which was likely due to the dominance of kinetic retention processes. We evaluated …

Cultivar, Juice Extraction, Ultra Violet Irradiation And Storage Influence The Stilbene Content Of Muscadine Grapes (Vitis Rotundifolia Michx.), Mark Rene' Leblanc

LSU Doctoral Dissertations

Stilbene concentration was analyzed in juice and tissue of muscadine grape (Vitis rotundifolia Michx.) and bunch grape (Vitis labrusca L.) from fresh fruit, after processing and after postharvest treatments. Five filter types were evaluated for percent resveratrol recovery when filtering standard and spiked juice samples in preparation for HPLC analysis. Only two (polycarbonate and Anopore) of the five filter types had more than 90 percent recovery. Polycarbonate was chosen for sample preparation since it was more durable during handling. Eight muscadine grape cultivars and three bunch grape cultivars were evaluated. Skin tissue had approximately 100 times higher stilbene concentration than …

Assessing The Coverage Carnage: Asbestos Liability And Insurance After Three Decades Of Dispute, Jeffrey W. Stempel

Scholarly Works

Often overlooked are the insurance issues related to asbestos and the degree to which the asbestos mass tort has changed the face of liability insurance and liability insurance law. The asbestos mass tort brought insurance coverage litigation into the big leagues of litigation, adjudication, and scholarly examination (although even the most rabid insurance coverage junkie would concede this is not much silver lining to the asbestos cloud). But after 30 years of big-time liability insurance coverage litigation involving asbestos or influenced by asbestos, what is the outcome? My assessment is:

1. Despite their protestations, insurers have not been unfairly treated …

Differential Expression And Detection Of Transcripts In Sweetpotato (Ipomoea Batatas (L.) Lam.) Using Cdna Microarrays, Cecilia E. Mcgregor

Microarray protocols were developed for sweetpotato (Ipomoea batatas (L.) Lam.) and then used to study issues of importance in sweetpotato physiology and production. The effect of replication number and image analysis software was compared with results obtained by quantitative real-time PCR. The results indicated that reliable results could be obtained using six replicates and UCSF Spot image analysis software. These methodologies were employed to elucidate aspects of sweetpotato development, physiology and response to virus infection. Storage root formation is the most economically important process in sweetpotato development. Gene expression levels were compared between fibrous and storage roots of the cultivar …

Do Overweight Inactive Parents Raise Overweight Inactive Children? Examination Of The Influence Of The Home Environment On Weight Status Of Children Over Time, Emily York-Crowe

LSU Doctoral Dissertations

The primary aim of this study was to test whether body mass index (BMI), psychosocial, and behavioral parental variables were associated with similar variables in children at baseline, and whether these variables also served as significant predictors of overweight status in children after two years. While there have been several cross-sectional studies examining the impact of parental behaviors and characteristics on similar variables in children, and several longitudinal studies predicting weight status, BMI percentile, and risk factors of disease in children over time, there is a paucity of research that has identified (cross-sectionally) and then tested (longitudinally) significant parental variables …

Jack Kerouac's Spontaneous Prose: A Performance Genealogy Of The Fiction, Justin Thomas Trudeau

LSU Doctoral Dissertations

This study analyzes Jack Kerouac’s writing method of spontaneous prose and articulates how the method can be understood as performative writing. Kerouac’s “Essentials of Spontaneous Prose,” On the Road, Visions of Cody, and Doctor Sax are explored to evaluate both the successes and failures of the author’s attempts to break literary boundaries and create a new writing method based upon spontaneous tenets. These three novels, which were written in succession from 1950 to 1953 when Kerouac was in his most productive period, represent both the emergence and dissent of the author’s use of performative writing. To explicate the cultural genesis …

Using The Rod: Education, Punishment, And The New Woman In Fin De Siã¨Cle British Literature, Kristin C. Ross

LSU Doctoral Dissertations

This study examines the relationship between female education and punishment in the British novel of the fin de siécle. It considers the “New Woman” (the emancipated, intellectualized, and unmarried prototypical feminist appearing in late nineteenth-century culture) in light of how female education affects fictional characterizations of her. Female education in the “New Woman” and her fictional counterparts worked to destabilize class and gender hierarchies for Victorian Society, producing anxiety in its culture and texts. To defuse this anxiety, authors frequently demonstrated the consequences of espousing the feminism driving the “New Woman” and the education producing her. The education she desired/received …

Measuring The Degree Of Market Power In The Export Demand For Soybean Complex, Dwi Susanto

LSU Doctoral Dissertations

Previous studies on market power hypothesis strictly assumed that the data used in the analysis were a stationary process. This assumption has been argued that not all time series exhibit a stationary process such that conventional asymptotic theory cannot be applied. This study adopts the “New Empirical Industrial Organization” (NEIO) approach developed by Bresnahan (1982) and Lau (1982) to measure the degree of market power in the export market for soybean complex. The non-stationary properties of the data were accommodated by formulating the model in an error correction framework (ECM) developed by Bårdsen (1989) and applied by Steen and Salvanes …

Assessment Of Interactions Amoung Viruses Infecting Sweetpotato, Charalambos D. Kokkinos

LSU Doctoral Dissertations

Viral diseases, especially those caused by mixed infections, are among the economically most important diseases of sweetpotato. Real-time PCR assays were developed for the detection and quantification of the potyviruses Sweet potato feathery mottle virus (SPFMV), Sweet potato virus G (SPVG), Ipomoea vein mosaic virus (IVMV); the crinivirus Sweet potato chlorotic stunt virus (SPCSV), and the begomovirus Sweet potato leaf curl virus (SPLCV) directly from infected sweetpotato plants. Titers of SPFMV, IVMV, and SPVG were lower in singly-infected sweetpotato plants compared to singly-infected plants of the standard indicator host Brazilian morning-glory (Ipomoea setosa) and the standard propagation host I. nil …

The Temporal And Spatial Scale Of Microevolution: Fine-Scale Color Pattern Variation In The Lake Erie Watersnake, Richard B. King, J.M. Ray

Faculty Articles, Papers, and Other Scholarship

Question: What is the temporal and spatial scale of microevolution? Hypotheses: The combined effects of natural selection and gene flow result in variation in heritable traits on fine spatial and geographic scales. Organism: The Lake Erie watersnake, Nerodia sipedon insularum. Field site: US and Canadian islands in western Lake Erie. Methods: We tested for variation in colour pattern frequency within islands, among islands, and over time using data from nearly annual censuses conducted since 1980, museum specimens, and published sources. We compared FST for a presumptive major colour pattern locus to FST for allozyme loci to determine whether spatial variation …
