The Usefulness And Predictability Of Net Realizable Values: An Empirical Study., Jerry Joseph Baudin Jan 1982

The Usefulness And Predictability Of Net Realizable Values: An Empirical Study., Jerry Joseph Baudin

LSU Historical Dissertations and Theses

The general objective of financial reporting is to provide useful information for making economic decisions. Net realizable value has been recommended and advocated as a valuation method that would improve the usefulness of reported fnancial information. One shortcoming of the net realizable value method is that there are no established used market prices for certain fixed assets, such as buildings. At present, there is no evidence indicating that a solution to this shortcoming has been found. Therefore, the purpose of this study is to empirically test the reliability of using specific price indexes in predicting net realizable values for certain …

Reducing Shoplifting Incidents Through The Use Of Signs., Jeffrey Allan Gottlieb Jan 1982

Reducing Shoplifting Incidents Through The Use Of Signs., Jeffrey Allan Gottlieb

LSU Historical Dissertations and Theses

This study consisted of three experiments designed to reduce the shoplifting rate of targeted merchandise in retail establishments without adversely affecting sales. In the first two experiments, attempts were made to replicate earlier findings suggesting that identifying frequently stolen merchandise would reduce its theft rate. In addition, signs were posted in locations where shoppers contemplated or carried out the act of shoplifting in order to achieve generalized reductions in shoplifting. Neither the signs identifying frequently stolen merchandise nor the signs identifying locations used by shoplifters had a consistent impact on any of the target merchandise. The third experiment was designed …

Microbial Products From Sweet Potato Wastes., Nhuan Phu Nghiem Jan 1982

Microbial Products From Sweet Potato Wastes., Nhuan Phu Nghiem

LSU Historical Dissertations and Theses

Microbial production of methane from alkaline sweet potato wastes was studied. Assessment of methane production potential was based on total COD of the wastes. A single-stage and a two-stage system were studied. In both systems, to ensure stable operation and high performance, methane fermenters had to be initially seeded with large quantities of methane formers. A 50% inoculum (based on total fermenter volume) was found to be most effective. Methane formers tended to aggregate to form spherical particles which had extremely high settling rates, this eliminated the requirement of cell recycle. They obtained the nutrients required for their growth through …

Rural Community Influentials: Participation In Local Voluntary Organizations., Jusoh Nordin B Muhamad Jan 1982

Rural Community Influentials: Participation In Local Voluntary Organizations., Jusoh Nordin B Muhamad

LSU Historical Dissertations and Theses

The purpose of this study is to identify the variables or types of variables that are possible predictors of organizational participation. Three categories of independent variables--ecological, situational, and individualistic variables are investigated. The sample consists of 442 rural community influentials from twelve counties in six southern states. Both the Spearman's test of correlation as well as multiple regression analysis are employed to assess the relationships among the independent and dependent variables. The zero-order correlations show that ecological variables (population size, percent white, and urbanization) and situational variables (organization availability and organization diversity) are generally highly correlated with organizational participation (p < 0.001). On the other hand, individualistic variables (occupation, education, age, and length of residence) are generally not significantly related to organizational participation, particularly in membership in influential organizations. The multiple regression analysis reveals that the three categories of variables account for about 20 percent of the variance in membership in influential organizations, and about 15 percent of the variance in the general measures of participation (simple memberships in any set of organizations, attendance at meetings and holding offices). Situational variables are found to have the most influence on membership in influential organizations, whereas population size (an ecological variable) is found to have the most influence on participation as indicated by the general measures of participation. Situational variables account for about 13.5 percent of the variance in membership in influential organizations, although the percentage of explained variance in the general measures of participation is less than 2 percent. Ecological variables, on the other hand, account for about 9 percent of the variance in organizational participation. One of the important tasks of the study is to examine whether organizational participation is related to community influence. Although there is some evidence that participation is associated with influence, the amount of variance explained by organizational participation is rather weak (less than 9 percent). Overall, the study suggests that structural variables (ecological and situational variables) are more important predictors of participation than individualistic variables. Hence, any explanation of the phenomenon of participation will be incomplete if structural factors are ignored.

Application Of Electroanalytical Techniques To Environmental Thallium Compounds., Linda Katherine Hoeflich Jan 1982

Application Of Electroanalytical Techniques To Environmental Thallium Compounds., Linda Katherine Hoeflich

LSU Historical Dissertations and Theses

Because of increasing concern over global pollution by the energy production industry, especially large, centralized utility complexes, the quantitation and speciation of heavy metals have taken on great importance. These metals are emitted with coal fly ash and may be subsequently deposited in natural waters. Complications arise when certain inorganic compounds undergo biomethylation by microbial action in these waters. Therefore, procedures must be developed to analyze and differentiate the mixture of inorganic and organometallic compounds present. This work is a study of the electrochemical properties of inorganic and organothallium compounds. The toxicological significance of thallium compounds is known, and their …

A Mechanistic Study Of Free-Radical Initiation Of Alkene Oxidation By Nitrogen Dioxide., John William Lightsey Jan 1982

A Mechanistic Study Of Free-Radical Initiation Of Alkene Oxidation By Nitrogen Dioxide., John William Lightsey

LSU Historical Dissertations and Theses

The reactions of part per million (ppm) levels of nitrogen dioxide with cyclohexene have been studied to serve as a model for the reactions that occur between nitrogen dioxide in smoggy air and unsaturated fatty acids in pulmonary lipids. Previous studies done at high nitrogen dioxide levels were confirmed by these studies with nitrogen dioxide at concentrations of 10,000 ppm and higher. These show that nitrogen dioxide reacts with cyclohexene predominantly by addition to the double bond; in the presence of air or oxygen this addition initiates the autoxidation of the alkene. However, at low ppm levels, nitrogen dioxide reacts …

Ion-Ion And Ion-Solvent Interactions In The System Sodium-Aluminum Tetraethyl-Benzene-Hmpa., James Harold Medley Jan 1982

Ion-Ion And Ion-Solvent Interactions In The System Sodium-Aluminum Tetraethyl-Benzene-Hmpa., James Harold Medley

LSU Historical Dissertations and Theses

The behavior of the system NaAlEt(,4)-benzene-HMPA as a function of the mole ratio HMPA:NaAlEt(,4) has been studied via equivalent conductance measurements, viscosity measurements and ('23)Na, ('27)Al and ('1)H nmr spectroscopy. This system has the property of forming two immiscible liquid phases. Therefore a careful analysis of the dependence of the lower phase volume on the mole ratio was undertaken. Additionally the uptake of benzene in the lower phase can be followed via nmr integration. The volume studies indicate a similarity in behavior of the anionic organoaluminum "liquid clathrate" compounds. The formation of two liquid phases has been related to the …

Luminescence Studies: Luminescence Of Aqueous Ionic Solutions; Temperature Dependence Of The Phosphorescence Of Phenanthene In Ethanol - Effects Of Gases., Terrence Lenoir Mathers Jan 1982

Luminescence Studies: Luminescence Of Aqueous Ionic Solutions; Temperature Dependence Of The Phosphorescence Of Phenanthene In Ethanol - Effects Of Gases., Terrence Lenoir Mathers

LSU Historical Dissertations and Theses

Part I. Luminescence of Aqueous Ionic Solutions. An anomolous luminescence of aqueous solutions of I('-), Br('-), OH('-) etc. is observed and appears to be characteristic of the solvent. The emission of a KBr solution is greatly reduced by purification of the KBr. However, upon addition of acids, this emission reappears. Since all of the ions involved are known to have charge transfer to solvent (CTTS) transitions, the luminescence is postulated to be due to the recombination of H(,3)O('+) and e('-). Hydroxide and hydrosulfide appear to be a special case and may be transferring a hydrogen atom to the water. Discussions …

Spectroscopy And Photochemistry Of Aromatic And Cyclic Beta-Diketones., Felipe Antonio Pascal Hamilton Jan 1982

Spectroscopy And Photochemistry Of Aromatic And Cyclic Beta-Diketones., Felipe Antonio Pascal Hamilton

LSU Historical Dissertations and Theses

(beta)-Diketones exist in a tautomeric equilibrium between the enol and the keto forms. The enol form is the most stable because of the formation of an intramolecular hydrogen bond. (beta)-Diketones in solution at 77K exhibit changes in their absorption and phosphorescence spectra upon irradiation with a powerful UV visible source. The changes observed in the molecule result from rupture of the intramolecular hydrogen bond. Once the hydrogen bond has been broken a distribution of conformers of the enol is possible. The formation of a negative ion can also result from the irradiation and a distribution of conformers of the negative …

Methane Production From Alkaline Food Waste., Wilson Thomas Gautreaux Jr Jan 1981

Methane Production From Alkaline Food Waste., Wilson Thomas Gautreaux Jr

LSU Historical Dissertations and Theses

Anaerobic digestion of an alkaline food waste for methane production was investigated. The waste generated by potato processing contained significant quantities of carbohydrate degradation products and sodium carbonate. Anaerobic digestion was determined to be a reliable process for waste treatment and methane production. The high sodium levels did not inhibit anaerobic digestion at a substrate concentration of 1.0 wt % alkaline peel solids. Single and two-stage (separate acid, methane stages) anaerobic digestion systems were studied. In two-stage bench-scale studies at 37(DEGREES)C, methane production averaged 0.28 m('3)/kg COD feed or 0.65 m('3)/(m('3)(.)d) in a settled bacterial sludge methane fermenter with a …
