Identification Of A Class Of Chromatin Boundary Elements, Olivier Cuvier, Craig M. Hart, Ulrich K. Laemmli Jan 1998

Identification Of A Class Of Chromatin Boundary Elements, Olivier Cuvier, Craig M. Hart, Ulrich K. Laemmli

Faculty Publications

Boundary elements are thought to define the ends of functionally independent domains of genetic activity. An assay for boundary activity based on this concept measures the ability to insulate a bracketed, chromosomally integrated reporter gene from position effects. Despite their presumed importance, the few examples identified to date apparently do not share sequence motifs or DNA binding proteins. The Drosophila protein BEAF binds the scs' boundary element of the 87A7 hsp70 locus and roughly half of polytene chromosome interband loci. To see if these sites represent a class of boundary elements that have BEAF in common, we have isolated and …

Overt And Relational Aggression In Russian Nursery-School-Age Children: Parenting Style And Marital Linkages., C. H. Hart, D. A. Nelson, C. C. Robinson, S. F. Olsen, M. K. Mcneilly-Choque Jan 1998

Overt And Relational Aggression In Russian Nursery-School-Age Children: Parenting Style And Marital Linkages., C. H. Hart, D. A. Nelson, C. C. Robinson, S. F. Olsen, M. K. Mcneilly-Choque

Faculty Publications

Maternal and paternal parenting styles and marital interactions linked to childhood aggressive behavior as described in Western psychological literature were measured in an ethnic Russian sample of 207 families of nursery-school-age children. Results corroborated and extended findings from Western samples. Maternal and paternal coercion, lack of responsiveness, and psychological control (for mothers only) were significantly correlated with children's overt aggression with peers. Less responsiveness (for mothers and fathers) and maternal coercion positively correlated with relational aggression. Some of these associations differed for boys versus girls. Marital conflict was also linked to more overt and relational aggression for boys. When entered …

Emergence Of Western Diseases In The Tropical World: The Experience With Chronic Cardiovascular Diseases, Terrence Forrester, Richard S. Cooper, David Weatherall Jan 1998

Emergence Of Western Diseases In The Tropical World: The Experience With Chronic Cardiovascular Diseases, Terrence Forrester, Richard S. Cooper, David Weatherall

Faculty Publications

Our knowledge of the disease burden components of tropical populations is fragmentary. Historically, the infectious diseases have been emphasized but, as some populations have undergone socio-economic changes, vital statistics have described a change in the pattern of disease. The picture is of a decline in infectious and a rise in chronic non-communicable disease. We focus here on the emergence of chronic cardiovascular diseases, and use hypertension as the paradigmic example. Early blood pressure surveys showed a virtual absence of hypertension among rural Africans and moderate prevalences in the Caribbean. Prevalence was highest among US and UK blacks. In a recent …

Accelerated Degradation Tests: Modeling And Analysis, William Q. Meeker, Luis A. Escobar, C. Joseph Lu Jan 1998

Accelerated Degradation Tests: Modeling And Analysis, William Q. Meeker, Luis A. Escobar, C. Joseph Lu

Faculty Publications

High reliability systems generally require individual system components having extremely high reliability over long periods of time. Short product development times require reliability tests to be conducted with severe time constraints. Frequently few or no failures occur during such tests, even with acceleration. Thus, it is difficult to assess reliability with traditional life tests that record only failure times. For some components, degradation measures can be taken over time. A relationship between component failure and amount of degradation makes it possible to use degradation models and data to make inferences and predictions about a failure-time distribution. This article describes degradation …

Susceptibility Of Field Populations Of Beet Armyworm (Lepidoptera: Noctuidae) To Commercial And Experimental Insecticides, V. J. Mascarenhas, J. B. Graves, B. R. Leonard, E. Burris

Faculty Publications

Susceptibility of field-collected strains of beet armyworm, Spodoptera exigua (Hübner), to commercial and experimental insecticides was evaluated in a diet overlay bioassay by using 2-d-old larvae. Larvae were collected from cotton, Gossypium hirsutum L., fields in Alabama, California, Louisiana, Mississippi, and Texas, and from Rio Bravo, Mexico. Several field strains exhibited reduced susceptibility to chlorpyrifos and thiodicarb, which are the only 2 labeled insecticides recommended for beet armyworm control in Louisiana. In chlorpyrifos bioassays, 7 of the 11 field strains had significantly higher LC50s than the reference strain from the Southern Insect Management Laboratory at Stoneville, MS. In thiodicarb bioassays, …

Genetic Evidence For The Proto-Austronesian Homeland In Asia: Mtdna And Nuclear Dna Variation In Taiwanese Aboriginal Tribes, Terry Melton, Stephanie Clifford, Jeremy Martinson, Mark Batzer, Mark Stoneking Jan 1998

Genetic Evidence For The Proto-Austronesian Homeland In Asia: Mtdna And Nuclear Dna Variation In Taiwanese Aboriginal Tribes, Terry Melton, Stephanie Clifford, Jeremy Martinson, Mark Batzer, Mark Stoneking

Faculty Publications

Previous studies of mtDNA variation in indigenous Taiwanese populations have suggested that they held an ancestral position in the spread of mtDNAs throughout Southeast Asia and Oceania (Melton et al. 1995; Sykes et al. 1995), but the question of an absolute proto-Austronesian homeland remains. To search for Asian roots for indigenous Taiwanese populations, 28 mtDNAs representative of variation in four tribal groups (Ami, Atayal, Bunun, and Paiwan) were sequenced and were compared with each other and with mtDNAs from 25 other populations from Asia and Oceania. In addition, eight polymorphic Alu insertion loci were analyzed, to determine if the pattern …

On Summability Of Distributions And Spectral Geometry, R. Estrada, J. M. Gracia-Bondía, J. C. Várilly Jan 1998

On Summability Of Distributions And Spectral Geometry, R. Estrada, J. M. Gracia-Bondía, J. C. Várilly

Faculty Publications

Modulo the moment asymptotic expansion, the Cesàro and parametric behaviours of distributions at infinity are equivalent. On the strength of this result, we construct the asymptotic analysis for spectral densities arising from elliptic pseudodifferential operators. We show how Cesàro developments lead to efficient calculations of the expansion coefficients of counting number functionals and Green functions. The bosonic action functional proposed by Chamseddine and Connes can more generally be validated as a Cesàro asymptotic development.

Variations In The Secondary Metabolite Camptothecin In Relation To Tissue Age And Season In Camptotheca Acuminata, Zhijun Liu, Stanley B. Carpenter, Wayne J. Bourgeois, Ying Yu, Roysell J. Constantin, Matthew J. Falcon, John C. Adams

Faculty Publications

We investigated variation in concentration of the secondary metabolite, camptothecin (CPT), in relation to leaf, branch and tree age, season, and leaf drying method in Camptotheca acuminata Decaisne saplings. Younger leaves contained higher CPT concentrations than older leaves. Within a branch, there was a linear decline in CPT concentration from leaves at the apex of the branch down to Leaf 7. Comparing leaves of similar age, those from younger trees had higher CPT concentrations than those from older trees. Over the course of the growing season, there was a steady decline of 11% per month in leaf CPT concentration. Branches …

Educational Technology And State Reform: Examining The First-Year Impact Of Louisiana's State Technology Policy On Public School Districts., Jeffrey Paul Gagne Jan 1998

Educational Technology And State Reform: Examining The First-Year Impact Of Louisiana's State Technology Policy On Public School Districts., Jeffrey Paul Gagne

LSU Historical Dissertations and Theses

During the 1990's educational technology became a major educational policy issue for every state (White, 1997; Education Commission of the States, 1997; National Council of State Legislators, 1996; Trotter, 1997). By early 1998, all 50 states had state-level technology plans in various stages of implementation, and state funding for educational technologies was rapidly increasing across the country (Trotter, 1997). The purpose of this study was to examine the impact of recently enacted Louisiana state-level technology reforms on public school district technology efforts between the 1996--97 and 1997--98 school years. Both quantitative and qualitative methods were used to collect data, creating …

Applications Of Band Ratioing At Fort Irwin, California., Alexander Wright Taylor Jan 1998

Applications Of Band Ratioing At Fort Irwin, California., Alexander Wright Taylor

LSU Historical Dissertations and Theses

This dissertation describes the results of two projects that demonstrate the power of band ratioing of remote sensing data. The first method, Band Ratio Differencing (BRD), challenges the more traditional techniques for detecting environmental disturbance of the surface in and terrains. These traditional techniques are inadequate because they cannot identify the nature of the change (physical, chemical, biological) or the processes (natural, anthropogenic) involved in causing the change. In contrast, BRD of Landsat TM data has the advantage of providing information about changes in the composition of alluvial surfaces. These compositional changes, when combined with empirical field data provides insight …

Living Arrangements Of The Elderly In The United States: Comparing Whites, Blacks, Hispanics, And Asians' Households., Kiyomi Ando Jan 1998

Living Arrangements Of The Elderly In The United States: Comparing Whites, Blacks, Hispanics, And Asians' Households., Kiyomi Ando

LSU Historical Dissertations and Theses

My dissertation analyzed the living arrangements of the elderly, focusing on differences across gender and racial/ethnic lines. Drawing upon rational choice and family solidarity theoretical perspectives. I derived hypotheses dealing with the effects of individual resources, cultural characteristics, and geographic context on the elderly's living arrangements. These hypotheses were empirically tested using logistic regression models to estimate the odds of the elderly choosing from among three options of living arrangements--independent living, joint living, and dependent living. Separate models were applied to non-Hispanic white, African American, Hispanic, and Asian subsamples. Data were from the 1990 Census Public Use Sample (PUMS-L). The …

Assessing Applicant "Fit" Within The Selection Process: Which Interviewer Perceptions Matter?, Dawn Ebe Haptonstahl Jan 1998

Assessing Applicant "Fit" Within The Selection Process: Which Interviewer Perceptions Matter?, Dawn Ebe Haptonstahl

LSU Historical Dissertations and Theses

The research literature has noted that organizations are moving beyond simply hiring individuals with the necessary knowledge, skills, and abilities (KSAs) that fulfill the requirements of the job--employers are also looking for people who can fit in with a particular work group or even an entire organization. This study tested an exploratory model that predicted recruiter selection decisions from their evaluations of applicants' person-job (P-J), person-group (P-G), and person-organization (P-O) fit. The model also postulated that P-G and P-O fit would be predicted by the perceived congruence (similarity) of work values between applicants and groups/organizations, Hypotheses were field-tested with 64 …

A Normative Study Of The Psychopathology Instrument For Mentally Retarded Adults (Pimra)., Kelley Lynne Francis

LSU Historical Dissertations and Theses

Indices were established for the Psychopathology Instrument for Mentally Retarded Adults (PIMRA) to signify that a particular score warranted further assessment. The subjects were 431 individuals with mild and moderate mental retardation in state schools and developmental centers in Texas and Louisiana. Almost 65% of the sample met the cutoff for further assessment using the newly established criteria, while approximately 40% of the sample had elevations on two or more of the subscales. Critical items were identified for the Schizophrenia, Affective Disorders, Somatoform Disorders, and Adjustment Disorders subscales. No significant differences were noted for gender with respect to the subscales. …

The Clarity Of The Modern: Or, The Ambiguities Of Henry James And Wallace Stevens., Gregory Angelo Marks Jan 1998

The Clarity Of The Modern: Or, The Ambiguities Of Henry James And Wallace Stevens., Gregory Angelo Marks

LSU Historical Dissertations and Theses

Clarity, in all its various guises, was before the advent of Romanticism looked upon as an unquestioned focus of attention and irrefutable goal of human endeavor. Conversely, ambiguity was seen negatively: it was in language an obstacle to communication; in ethics, an indecisiveness failing action; and in ontology and aesthetics, a slovenly disorder. With Romanticism, this basic consensus regarding these terms ends. No longer an expression of censure, ambiguity is imagined as a liberatory force. Clarity, if attainable at all, is dismissed as mere rigidity. The works of Americans Henry James and Wallace Stevens embody and enact this tension and …

Using Mathematical Modeling For The Prediction Of Success In Developmental Math., Kathy Rogers Autrey

LSU Historical Dissertations and Theses

This exploratory study was primarily designed to determine the possibility of developing a discriminant model to predict success in developmental mathematics. The sample included 402 students enrolled in a developmental math class at Northwestern State University, a small public school in North Louisiana, in the fall semester of 1996. Demographic, achievement and attitudinal variables were used in the development of the model. High school GPA, social enrichment scores from the College Student Inventory, and black were factors identified as significant in the model. Although limited in its predictive ability, the model does provide faculty and advisors with additional information to …

Evaluation Of The Toxicological Consequences Of Dietary Exposure To Individual Classes Of Polycyclic Aromatic Hydrocarbons Or A Mixture In The Fischer-344 Rat., Mary Durand Boudreau Jan 1998

Evaluation Of The Toxicological Consequences Of Dietary Exposure To Individual Classes Of Polycyclic Aromatic Hydrocarbons Or A Mixture In The Fischer-344 Rat., Mary Durand Boudreau

LSU Historical Dissertations and Theses

There is special concern about the potential health effects of by-products released into the environment after combustion or conversion of fossil fuels. Polycyclic aromatic hydrocarbons (PAH), while initially released largely into the atmosphere, are subsequently deposited in soil and water and on foods. Although the significance of PAH contamination with regard to environmentally caused diseases and cancer in humans is difficult to estimate, it is suggested that the potential hazards may be underestimated. In an effort to understand the potential adverse health effects of PAHs, a comprehensive study was undertaken to determine the metabolic fate of selected PAHs as individual …

The Effects Of Gender And Race On Physician Treatment Of Patient Emotion., Vaughn A. Decoster Jan 1998

The Effects Of Gender And Race On Physician Treatment Of Patient Emotion., Vaughn A. Decoster

LSU Historical Dissertations and Theses

This study established theoretical and empirical foundations for the investigation into how physicians deal with (treat) patient emotion. The questions posed, "Do physicians employ specific strategies to treat patient emotion?" and "What are the effects of physician-patient social characteristics (gender and race) on emotion treatment?" Coalescing two seemingly incongruent perspectives (social constructionism and Kemper's social relational theory), I clarified the conceptual basis for the emotion management of other people. From these perspectives, I developed a three stage theory to describe and explain the physician treatment of patient emotion (triaging, diagnosing, and treatment), as well as appreciate the effects of social …

Marginal Employment In The United States: 1971-1993., Nicole Thomson Flynn Jan 1998

Marginal Employment In The United States: 1971-1993., Nicole Thomson Flynn

LSU Historical Dissertations and Theses

In this dissertation, I examine trends in production and the concomitant demographic transformation of the labor force, in the context a series of economic cycles since 1969. Using these three forces as a backdrop, I first consider changes in employment hardship and the forces contributing to underemployment during periods following economic recessions. Then, I examine differences between men and women for employment outcomes. Next, to explain hardship during these periods, I include important demographic and geographic factors related to underemployment. Finally, I examine the impact of labor market context on individual outcomes. Based on the transformation of work, I explain …

Characterization Ofp53 Gene Sequence In Exons 5-8 Of The Western Mosquito Fish, Gambusia Affinis., Neeraja Kondapi Erraguntla

LSU Historical Dissertations and Theses

Cancer is a multistage disease that involves both genetic and epigenetic factors. The number of physical and chemical agents with which human beings come in contact on a regular basis is increasing everyday. Somatic mutations can result due to such exposures and trigger uncontrolled cell division resulting in cancer. The p53 tumor suppressor gene has been identified in several vertebrate species ranging from man to fish. In addition, inactivation of p53 has been observed in a wide variety of tumors. Fish models are becoming increasingly popular for assessing environmental exposure. Low background incidence of mutations, relatively low cost tumor studies, …

Adjective Acquisition: Developmental Changes In The Use Of The Shape Bias, Syntax, Shape Consistency, And Semantic Attributes., Lenore Carol Frigo Jan 1998

Adjective Acquisition: Developmental Changes In The Use Of The Shape Bias, Syntax, Shape Consistency, And Semantic Attributes., Lenore Carol Frigo

LSU Historical Dissertations and Theses

When learning vocabulary, children must determine the meaning of each word that they hear. In hypothesizing about word meanings, children follow certain principles that simplify vocabulary acquisition. Among these principles are several that lead children to follow a shape bias. Under the shape bias, children assume that words extend to objects that share a common shape. This shape bias is useful for learning count nouns, which often include whole-object shape as an important aspect of meaning. However, the shape bias is not useful for the development of other word classes, such as adjectives. In this study, several variables were examined …

Using Academic And Demographic Variables To Predict Success In The General Education Curriculum., Steven Giles Horton

LSU Historical Dissertations and Theses

Student success and attrition in all levels of education is becoming a more important issue in an age where education dollars are diminishing while various schools of higher learning are increasing. As a result, schools are reevaluating their current programs of study in an attempt to determine if both students and universities are fulfilling their respective goals. This process of reevaluation has several fundamental considerations, one of these which is addressed in this study--the effectiveness of prerequisite requirements and other demographic variables on predicting the success of students in courses in the general education curriculum. The purpose of this study, …
