Systemic Studies Of The Genus Gila (Cyprinidae) Of The Colorado River Basin, Paul Bernard Holden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three Hundred and nine specimens of Gila from the Colorado River basin were studied. A form of numerical taxonomy, taximetrics, was used to help classify the specimens. The data from these fish indicate that many of the present hypotheses concerning their taxonomy are not valid. The concept of ecosubspecies or ecological subspecies does not fit the Colorado basin Gila. The roundtail and bonytail chubs, G. robusta Baird and Girard and G. elegans Baird and Girard respectively, currently treated as subspecies, are well separated morphologically, ecologically and reproductively and therefore are better considered two valid species. The relationship between G. …

Teacher's Attitudes And Teacher's And Student's Knowledge Of Alcohol And Alcoholism In Selected Utah High Schools, Ladawn Anderson Gibbons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparison of teacher's attitudes and teacher's and student's knowledge of alcohol and alcoholism were studied in nine selected high schools in Utah.

It was found that some teachers knew important positive facts about alcohol and alcoholism, but when personal obligations were written into "attitude" questions, their responses changed.

Some health and driver education teachers were poorly informed on the subject of alcohol and alcoholism. Some important facts known by teachers were either being deleted from instruction on alcohol or not being communicated very well.

In some schools it appears that students are learning about alcohol and alcoholism from other …

The Value Of A Trout Stream Fishery, Archie Allen Dyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data analysis indicated that travel distance, user age, and user income level are important determinants of use of trout streams.

These variables were incorporated into regression analysis to develop a use-prediction model.

This use-prediction model was used to determine predicted use levels of sample streams. The predicted use levels combined with travel costs and expenditures on new fishing equipment were used to derive a statistical estimate of the demand schedules for the sample streams.

These statistical demand curves were subjected to consumer surplus procedures to determine the values of the sample streams.

The Corporate Image Of Utah State University, Jon I. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past four years it has been easy to see that there has been no art direction in the visual communications of Utah State University. Recently the university has become aware of the importance of a good public relations program and has taken steps in that direction. Very little thought has been given to the visual design of these public relations though. Advertising gives information, plants ideas, and provokes interest in a service and company, but it must be designed well to be noticed. Corporate image includes many things, but I shall only deal with the visual or graphic …
