A Social Skills Measure For Adults With Mild Or Moderate Mental Retardation: Development Of The Measure Of Observable Social Skills (Moss)., Debra Farrar-Schneider Jan 1995

A Social Skills Measure For Adults With Mild Or Moderate Mental Retardation: Development Of The Measure Of Observable Social Skills (Moss)., Debra Farrar-Schneider

LSU Historical Dissertations and Theses

The literature on the history, definition, etiology, and assessment of social skills in mentally retarded adults was reviewed and the lack of adequate assessment measures was noted. Given the importance of social skills for mentally retarded individuals, especially in the area of community adjustment (e.g., residential and vocational placements), a behavioral checklist to assess these skills was developed. The Measure of Observable Social Skills (MOSS) was derived from reviewing social skills assessment and treatment literature, questionnaires, rating scales, and checklists. Two forms, each containing 47 different items, were developed and completed by caregivers of 212 mild to mentally retarded adults. …

The Church In Post-Transition Societies: Evidence From Eastern Europe., Mary L. Gautier Jan 1995

The Church In Post-Transition Societies: Evidence From Eastern Europe., Mary L. Gautier

LSU Historical Dissertations and Theses

I explore the relationship between religious affiliation and support for democratic values in postcommunist societies. Using the Tocquevillian idea of the institutional learning of democratic values within civil society, I examine three post-transition countries of Eastern Europe for evidence that the churches preserved and promoted democratic values during the years of Soviet regime control. Comparative historical examination of the relationship between the institutional churches and the state during the years of communist regime control demonstrate how the churches worked to preserve and promote democratic values. In those countries where the churches were marginalized and excluded from power by the state …

Using Drawing Tasks To Communicate Ideas About Photosynthesis: A Conceptual Change Strategy For Use In The Elementary School Classroom., Byron Levy Launey Jan 1995

Using Drawing Tasks To Communicate Ideas About Photosynthesis: A Conceptual Change Strategy For Use In The Elementary School Classroom., Byron Levy Launey

LSU Historical Dissertations and Theses

It is difficult for a teacher to determine if a learner has acquired an accurate concept of the topic being taught. Most of the children in this study had sufficient language skills to communicate successfully with their teachers even though they held inappropriate concepts of photosynthesis. This study examined the use of drawing tasks to assess children's ideas related to photosynthesis in an elementary-grade classroom. Two research questions guided the study to determine if this strategy was a valid improvement over traditional methods of classroom instruction. The first question asked if elementary-grade students receiving instruction about photosynthesis would acquire and …

The Influence Of Subject Sophistication On The Ability To Feign Mild Head Injury Symptoms., Roy Clayton Martin Jan 1995

The Influence Of Subject Sophistication On The Ability To Feign Mild Head Injury Symptoms., Roy Clayton Martin

LSU Historical Dissertations and Theses

The present study examined the effects that personal experience with head injury, task specific instruction and brain injury knowledge have on the ability to feign postconcussion symptoms and neuropsychological performance patterns seen in mild head injured patients. A sample of non-head injured and head injured college students served as the experimental subjects. These subjects were randomly assigned to conditions in which they were told to either do their best, feign deficits consistent with mild head injury without task specific instruction, or feign deficits while given task specific instruction. Subjects were also classified into one of two head injury knowledge groups …

Seen And Unseen Cities: Embodied Worlds In Epic And The Novel., Eamon G. Halpin Jan 1995

Seen And Unseen Cities: Embodied Worlds In Epic And The Novel., Eamon G. Halpin

LSU Historical Dissertations and Theses

By all accounts, the city has ceased to function as a cosmos, a coherent world which can offer meaning and validity to the lives of its inhabitants. If the ancient city presented the very image of order, the city since the advent of the Industrial Revolution has appeared to us as a jungle, a wilderness, a wasteland, an endless labyrinth--all images which suggest an essentially chaotic space, one which lacks any organizing principle or rationale. Moreover, if the city once offered the individual the greatest possible realization of his freedom, it now appears as the space in which he is …

A Two Dimensional Vertically Integrated Moving Boundary Hydrodynamic Model In Curvilinear Coordinates., Vibhas Aravamuthan Jan 1995

A Two Dimensional Vertically Integrated Moving Boundary Hydrodynamic Model In Curvilinear Coordinates., Vibhas Aravamuthan

LSU Historical Dissertations and Theses

A two dimensional, vertically averaged, hydrodynamic mathematical model on an adaptive boundary fitted grid is developed. This model addresses numerous drawbacks in the traditional finite difference models and incorporates such features as moving boundaries due to tidal incursion, and the ability to resolve irregular coastline geometries. A semi-implicit finite difference scheme is developed in order to overcome time step restrictions due to the gravity wave stability criterion. An eulerian-lagrangian formulation is used to solve the hydrodynamic equations on unsteady grid systems. The model is applied to study circulation features in Lake Pontchartrain (a medium sized physical system) and to the …

Notions Of Happiness In Rousseau's "Julie"., Peter Buttross Jr Jan 1995

Notions Of Happiness In Rousseau's "Julie"., Peter Buttross Jr

LSU Historical Dissertations and Theses

This enquiry first establishes both the importance and the general meaning of the notions of happiness in Rousseau's corpus. Both private and public happiness are seen as the overarching intent of his life as a thinker. The possibility of a tertiary notion of happiness--between private and public--is presented with the introduction of the subject work Julie; or The New Heloise. Themes considered at some length are passion/virtue, happiness/duty, love/friendship, as well as the notions of Platonic and courtly love--not to mention the dichotomy motion/rest. At the end of Part One of the novel, the lovers are forcibly separated, and the …

Some Problems In Algebraic And Extremal Graph Theory., Edward Tauscher Dobson Jan 1995

Some Problems In Algebraic And Extremal Graph Theory., Edward Tauscher Dobson

LSU Historical Dissertations and Theses

In this dissertation, we consider a wide range of problems in algebraic and extremal graph theory. In extremal graph theory, we will prove that the Tree Packing Conjecture is true for all sequences of trees that are 'almost stars'; and we prove that the Erdos-Sos conjecture is true for all graphs G with girth at least 5. We also conjecture that every graph G with minimal degree k and girth at least $2t+1$ contains every tree T of order $kt+1$ such that $\Delta(T)\leq k.$ This conjecture is trivially true for t = 1. We Prove the conjecture is true for …

Abstract Volterra Equations., Mihi Kim Jan 1995

Abstract Volterra Equations., Mihi Kim

LSU Historical Dissertations and Theses

This dissertation is devoted to the study of the abstract Volterra equation $$v(t) = A\int\sbsp{0}{t}\ v(t - s)d\mu(s) + f(t)\qquad{\rm for}\ t\ge0,\eqno&(\rm VE)$$. where A is a closed linear operator in a complex Banach space $X,\ \mu$ is a complex valued function of local bounded variation, and $f:\lbrack0,\infty)\to X$ is continuous and Laplace transformable. Laplace transform methods are used to characterize the existence and uniqueness of exponentially bounded solutions v for a given forcing term f, an operator A, and a given kernel $\mu$. We extend the methods of a solution family (or a resolvent) for (VE) by studying integrated …

Continuously Differentiable Selections And Parametrizations Of Multifunctions In One Dimension., Craig Knuckles Jan 1995

Continuously Differentiable Selections And Parametrizations Of Multifunctions In One Dimension., Craig Knuckles

LSU Historical Dissertations and Theses

Sufficient conditions are given for a multifunction (set-valued function) to admit a continuously differentiable selection in one dimension. These conditions are given in terms of Clarke generalized gradients of the Hamiltonian associated with the multifunction. Also, the multifunctions in one dimension that can be parametrized with continuously differentiable functions are completely characterized. The characterization is again in terms of Clarke generalized gradients of the Hamiltonian associated with the multifunction.

A Comparison Of Ecological Factors Affecting Two Species Of Lotic Molluscs., Paul David Johnson Jan 1995

A Comparison Of Ecological Factors Affecting Two Species Of Lotic Molluscs., Paul David Johnson

LSU Historical Dissertations and Theses

This study examined habitat-mediated differences in the population structure of two species of stream molluscs, the Louisiana pearl-shell mussel, Margaritifera hembeli, a protected species, and Elimia semicarinata, a pleurocerid gastropod. In 1991 I located Margaritifera hembeli in a drainage system where it was previously unknown, and describe here the distribution of M. hembeli in the Bayou Rigolette drainage in Grant Parish, Louisiana. The mussel was limited to small second- and third-order lotic systems. Of several physicochemical and habitat parameters, specific conductance, Ca$\sp{+2}$ concentration, sediment particle size, sediment compaction and channel width were most important in explaining abundance. Substratum stability was …

An Integrated Model Of Job Satisfaction., Mark Stephen Nagy Jan 1995

An Integrated Model Of Job Satisfaction., Mark Stephen Nagy

LSU Historical Dissertations and Theses

A model of job satisfaction is proposed that integrates the components of discrepancy, equity, need, value and valence theories using a control theory framework. Data was collected from 341 full-time employees from a variety of organizations. The results indicated support for the proposed model. The results illustrated that discrepancies are largely involved in both facet and global evaluations of job satisfaction and that the interaction of discrepancies and importance is instrumental in explaining global satisfaction. The results also demonstrated that comparison others are involved in the evaluation of job satisfaction and that different comparison others are associated with present and …

On The Relationship Between Representation Equivalence And Isomorphism Of Fundamental Groups Of Three-Step Nilmanifolds., Colathur Raja Vijayan Jan 1995

On The Relationship Between Representation Equivalence And Isomorphism Of Fundamental Groups Of Three-Step Nilmanifolds., Colathur Raja Vijayan

LSU Historical Dissertations and Theses

This dissertation arose from efforts to investigate an example which appeared in (G) of a phenomenon which has been considered to be rare: namely, the existence of two discrete cocompact subgroups $\Gamma\sb1$ and $\Gamma\sb2$ in a Lie group G such that $\Gamma\sb1/G$ and $\Gamma\sb2/G$ have the same (unitary) spectrum but $\Gamma\sb1$ is not isomorphic to $\Gamma\sb2.$ This phenomenon may be called representation equivalence of $\Gamma\sb1$ and $\Gamma\sb2$ with $\Gamma\sb1$ non-isomorphic to $\Gamma\sb2.$. In (G) the first known example of this phenomenon in the class of solvable Lie groups was given. In this example G was a specific three-step nilpotent Lie …

Popular Theatre In Eighteenth- And Nineteenth-Century Vienna: Stage Characters And Performance Sites., Gregory John Dykhouse Jan 1995

Popular Theatre In Eighteenth- And Nineteenth-Century Vienna: Stage Characters And Performance Sites., Gregory John Dykhouse

LSU Historical Dissertations and Theses

This dissertation pursues a relationship between the changing venues of the Viennese popular theatrical tradition, or Wiener Komodie, and the evolution of the comic figure from the performances of Josef Anton Stranitzky (1676-1726) to Johann Nestroy (1801-1862). This study follows a procedure of reconstructing the major venues associated with the Viennese comic tradition and analyzing the changes in the depiction of the comic character as they relate to the changes in the venues. This presentation of Viennese performance sites and stage characters ultimately explores the relationship between physical space (object of material culture, such as a purpose-built theatre) and theatrical …

In Vitro Maturation, In Vitro Fertilization And Development Of Bovine Oocytes., Li Zhang Jan 1995

In Vitro Maturation, In Vitro Fertilization And Development Of Bovine Oocytes., Li Zhang

LSU Historical Dissertations and Theses

To improve the efficiency of the culture system for bovine in vitro fertilization (IVF), several factors affecting the success of in vitro maturation (IVM), IVF and in vitro culture (IVC) of bovine oocytes were studied. A simple and efficient procedure has been developed for IVM/IVF/IVC of bovine follicular oocytes, which consistently produced 45 to 50% morulae and blastocysts during the treatment of over 6,000 oocytes. Ovary holding temperatures of $\rm 0\sp\circ C,\ 18\sp\circ C\ and\ 25\sp\circ C$ were found to affect the rate of maturation, fertilization and cleavage (P $<$ 0.05). When ovaries were held at 25$\sp\circ$C for 3 h, 20% of the oocytes developed to blastocysts and hatched in vitro, indicating that this temperature is suitable for holding ovaries during transportation. The highest cleavage rate (79%) was obtained when oocytes were matured and fertilized both at 39$\sp\circ$C in 5% CO$\sb2$. Fertilization rate was impaired with a lowered incubation temperature (37$\sp\circ$C) and CO$\sb2$ level (2.5%). Cumulus cells were shown to be important and necessary for IVM and acquisition of competence for full embryonic development. Cumulus cell removal before IVM, before IVF or 7 h after IVF reduced the rates of maturation, fertilization and development at all embryo stages evaluated (P $<$.05). Cumulus cell removal at 20 h after fertilization resulted in a rate of development similar to control embryos (P $>$.05). Co-culture enhanced the development of IVF-derived embryos. More embryos …

Gulf Literacy: A Marine Science-Based Model Of Scientific Literacy., John Edward Trowbridge

LSU Historical Dissertations and Theses

A trend in science education reform is the move towards the goal of scientific literacy. Attributes of scientific literacy include: (a) understanding key concepts and principles of science; (b) understanding newspaper articles and graphics related to science issues; and (c) using scientific ways of evaluating evidence for individual and societal purposes (AAAS, 1989; Demastes & Wandersee, 1992). Furthermore, BSCS (1993) has proposed a model of biological literacy that includes four distinct levels (nominal, functional, structural, and multidimensional). The Gulf of Mexico and its coastal environments are of social, economic and scientific importance. An understanding of the Gulf of Mexico in …

Dietary Chromium Supplementation For Pigs And Chickens., Terry Lynn Ward Jan 1995

Dietary Chromium Supplementation For Pigs And Chickens., Terry Lynn Ward

LSU Historical Dissertations and Theses

Three experiments were conducted with pigs and four experiments were conducted with chickens to determine the effects of supplemental dietary Cr on growth performance, carcass characteristics, tissue minerals and plasma metabolite and hormone concentrations. In pigs (Exp. 1) 200 ppb Cr from seven different sources tended to decrease performance during the grower phase and increase growth performance during the finisher phase. Dietary Cr had minimal effects on plasma metabolite and hormone concentrations and Cr did not affect carcass characteristics. In general, dietary Cr increased tissue Cr concentration, except for longissimus muscle (LM). In Exp. 2, pigs were fed 400 ppb …

Binding Of Hepatic Nuclear Proteins From Obese And Lean Zucker Rats To The Upstream Region Of Malic Enzyme Gene., Yibing Wang Jan 1995

Binding Of Hepatic Nuclear Proteins From Obese And Lean Zucker Rats To The Upstream Region Of Malic Enzyme Gene., Yibing Wang

LSU Historical Dissertations and Theses

Adrenal glucocorticoids are essential for the development of all forms of experimental obesity. In the obese (fa/fa) Zucker rats, adrenalectomy prevents the further development of obesity, and glucocorticoid replacement restores the obese phenotype. We have hypothesized that this dependence on glucocorticoids is due to differences in transcriptional regulation of a group of genes that are normally regulated by glucocorticoids. We have chosen to study the DNA fragments from the upstream region of the malic enzyme (ME) gene, which is positively regulated by glucocorticoids. Hepatic nuclear extracts from lean and obese Zucker rats were used in band shift studies to look …

Modelling A Multispecies Schooling Fishery In An Upwelling Environment, Mauritania, West Africa., Sidina Ould Dedah

LSU Historical Dissertations and Theses

Off Mauritania, Northwest Africa, small pelagic fish have long been a valuable target of a large and diverse international fleet. In the early 1990's, average annual catch was about 400,000 metric tons in which three to four families were frequently represented: carangidae (Trachurus trachurus, T. trecae and Decapterus rhonchus); clupeidae (Sardina pilchardus, Sardinella aurita and S. maderensis); scombridae (Scomber japonicus); and lately, trichiuridae (Trichiurus lepturus). Using empirical orthogonal function analysis, it was shown that the study area is a transition zone between permanent upwelling in the north (20-25$\sp\circ$N) and regions with seasonal upwelling in the south (10-16$\sp\circ$N). Also, from 1985 …

Data Analysis Using Reconstructability Theory., Deky Dicky Joe Gouw Jan 1995

Data Analysis Using Reconstructability Theory., Deky Dicky Joe Gouw

LSU Historical Dissertations and Theses

In this dissertation, we develop a new data analysis method using reconstructability theory, particularly k-systems theory. K-systems or Klir systems theory is a branch of reconstructability theory and provides a setting wherein common problems in statistics can be solved using the power of information theory by invoking the maximum entropy principle. The method is superior over classical statistical data analysis. The approach starts with the concept of variable interaction in reconstructability analysis (RA), We then use the RA definition of interaction to improve the quality of main and interaction effects in data analysis. With classical statistical data analysis, we need …

A Cross-Case Analysis Of Middle School Reading Teachers' Theoretical Orientations As They Relate To Classroom Practices., Shirley Theriot Fogleman Jan 1995

A Cross-Case Analysis Of Middle School Reading Teachers' Theoretical Orientations As They Relate To Classroom Practices., Shirley Theriot Fogleman

LSU Historical Dissertations and Theses

Each interaction between teachers and students is a reflection of the theory that these professionals, sometimes unknowingly, posit about what should be occurring in their classrooms. The purpose of this study is to explore the differences between middle school language arts teachers' beliefs about how children actually read a text, and how these teachers translate these beliefs into classroom practices. The beliefs we hold about reading comprehension are essential to our understanding about how we should instruct and assess our students in our classes. Leu and Kinzer (1988) refer to two beliefs' frameworks of comprehension in reading, based on the …

Bamboo Specialization In Amazonian Birds., Andrew Ward Kratter Jan 1995

Bamboo Specialization In Amazonian Birds., Andrew Ward Kratter

LSU Historical Dissertations and Theses

By spot-mapping territories of lowland forest birds in southeastern Peru, 19 "bamboo specialists" were documented to be restricted to thickets of bamboo (Guadua weberbaueri). Six specialists are restricted to thickets throughout their entire geographic range (obligate bamboo users); seven specialists may use other habitats sparingly away from southeastern Peru (near-obligate bamboo users); the remaining six species are frequent users of habitats lacking bamboo in area besides southeastern Peru (facultative bamboo users). The 19 specialists, all insectivorous, were classified into five guilds based on foraging maneuver and substrate preferences: four sallying tyrannid species; four arboreal antbirds; four stem-searching specialists; four dead-leaf-searching …
