Attitudes And Behavior Of Educators Involved In Confluent Teaching, Martin M. Koller

Theses and Dissertations

The study attempted to clarify the relationships between expressed attitude and observed teacher behavior. The purpose was to find positive ways of causing educators to incorporate cognitive and affective processes into their educational activities. At the same time, ways of meeting student needs in a confluent setting were sought.

The review of the literature provided relevant information already available through the efforts of other researchers. A multidiscipline approach in this review resulted in several conclusions:

1. Certain bio-self needs result in feelings that cause behavior.

2. Feelings and learning can be correlated so that behavior change takes place.

3. Learning …

Symbolic Civic Awareness: A Study Of Political Socialization In The City Of Grand Forks, Richard J. Hardy

Theses and Dissertations

Numerous studies in political socialization have suggested that the child's political world begins about the age of three and is basically- completed by age thirteen. Using this finding as a guideline, the author proposed in this study to determine at what age elementary school children develop a symbolic awareness of their government.

Based on a format similar to that used by Greenstein, Hess, and Easton, a study was made in the City of Grand Forks involving 951 children in grades one through six. To achieve representativeness and control, six elementary schools were selected based on socio-economic, philosophic, and religious variable. …

The Effects Of Different Gases On Excystation Of Coccidian Oocysts, James B. Jensen

Theses and Dissertations

Excystation of coccidian oocysts is a diphasic process where CO2 and suitable reducing agents cause changes in oocyst wall permeability (phase I) allowing the entrance of trypsin and bile which activate the sporozoites (phase II). This project was an indirect study of the mechanism of CO2 action by the substitution of NO, NO2, N2O, H2S, SO2 , CH4, NH3 and 8M urea in place of CO2. Changes in oocyst wall permeability of Eimeria stiedae, E. bovis and E. tenella were determined by incubation with the reagents and cysteine HCl followed by treatment with trypsin and bile to initiate activation of …

Bionomics And The Influence Of Diet Upon The Maturation Of Orchopeas Leucopus (Baker), Lynden Phillip Baum

Theses and Dissertations

Knowledge of the bionomics of plague vectors, es-pecially factors which influence life history, host pre-ference, and fluctuations of flea populations, are basic to an understanding of plague ecology. Orchopeas leucopus (Baker), an ectoparasite of cricetid rodents such as Peromyscus maniculatus (Wagner), and Peromyscus truei (Baird), is a vector of plague in the western United States (Holdenried and Morlan, 1955). In a study of nine biotic corrnnunities in the Utah portion of the Great Basin, P. maniculatus was the most abundant rodent in seven of the biotic corrnnunities (Olsen, 1966). Because of the ubiquitous nature of P. maniculatus an interchange of …

Lipids Of Fungal Spores, Identification And Metabolism, Jim L. Bushnell

Theses and Dissertations

The lipids of the spores of the Basidiomycetes: Ustilago bullata, Lycoperdon perlatum and Calvatia gigantea were investigated. The spores of U. bullata were found to have hydrocarbons ranging from C_9 to C_24, methyl esters of fatty acids ranging from C_14 to C_24, and free fatty acids from C_14 to C_24. The spores of L. perlatum were found to have few hydrocarbons (C_22 being the predominent one); no methyl esters were detected and the fatty acids were from C_15 to C_18. Long chain aldehydes (C_30) were also detected in low concentration. At the ultrastructural level the Lycoperdon spores were found to …

The Effects Of Temperatures And Chemicals On The Oocysts Of Eimeria Stiedae, Charles Larry Keehner

Theses and Dissertations

A study was made of the effects of temperatures and chemicals on the unsporulated and sporulated oocysts of Eimeria stiedae. In general, oocysts were affected by temperatures lower than -10 C and above +39 C, while normal development occurred between these temperatures. Unsporulated oocysts were more tolerant to temperature extremes, as they survived up to 8 days at 39 C and 12 days at -28 C. Sporulated oocysts were killed after 24 hours storage at 39 C and 4 days at -28 C. Oocyst resistance to low temperatures was not improved if unsporulated and sporulated oocysts were conditioned before and …
