- Description:
- Cancer is the second leading cause of death among women in the United States, and breast cancer kills more women than any other type of cancer. This study is an attempt to utilize personality variables to determine which women have a high risk of developing cancer of the breast. To achieve this end, a group of 115 women with either breast cancer, benign breast growths, or no growths was administered a relatively short, simple personality inventory, the Guilford-Zimmerman Temperament Survey. The personality variables, along with age, were utilized in successive multiple linear regressions until a relationship was achieved which appeared to have discriminatory value. The final regression equation was: Y = 21.7418- .0579A + .0481G- .0476R- .1036F + .028T where A = age G = general activity R = restraint F = friendliness T=thoughtfulness Using an arbitrary cut off score of 18.2, through the use of the equation 87.5 percent of the women with cancer were successfully identified as belonging to the cancer group and 50 percent of the normal patients were correctly identified as noncancerous. Of the group of patients with benign growths, half were identified as cancerous and half as normal. The goal of differentiating between women with and without breast cancer was achieved for this particular group of women with about half of the contribution made by the personality variables and the remainder by age.

- Description:
- This series of paintings demonstrated horizontal configurations of interrelating bands of color. The problem is to present a composition, within a rectangular framework, allowing for maximum color juxtaposition within a severely non-representational format. Color is the dominant motif and the key to the composition. The system devised is one in which maximum juxtapositions are possible. Since there is no fixed point of focus, the color causes optical expansions and contractions over the whole surface. This optical “excitement” is one aim of the exploration into color.

- Description:
- The solution of unbalanced electrical circuits has been found to be most practical by the method of Symmetrical Components. It is very powerful analytical tool and is based on sound theory. This project is intended to meet the needs of the practicing engineer and the engineering student. It presupposes a knowledge of fundamental single phase and poly phase circuit theory and the operating characteristics of the more important types of alternating current apparatus. A theoretical analysis is based on the assumption of three phase abc system. The paper was undertaken to investigate the characteristics of loads, when the systems are connected in three different ways . These three connections are star connected loads, grounded star connected loads and delta connected loads. Results from these informations are then developed into the “a” matrix transformation in each case, The advantages of these matrix trans formations are essential to be able to look at the phase diagram and immediately write the necessary sequence components from it. This paper also deals with the three phase, two winding transformers, From the knowledge of the Symmetrical Components are then decomposed the voltages and currents into a matrix equation which lead us to the solution of the equivalent circuits of the trans formers. Three different connections of two winding transformers were created to study (Delta-Delta connection, Star-Star connection and Star-Delta connection). The illustration involving the applications of the Symmetrical Components to solve the unbalanced three phase system is also presented in this paper.

- Description:
- A study was undertaken as a part of a larger, more detailed dissertation of the development of the Independent State Banks in California from 1945-1964. The primary source of information for such a study is the Annual Report by the Superintendent of Banks, State of California for each of the years covered. Information was put in a computer-readable form, a program was written, and the General Electric "420" Computer was used to compile and compute various totals and ratios for approximately 125,000 separate entries. The resulting output was used to study the development of the State Chartered Banks over the twenty-year period. The first area covered was the change in Capital Funds in the total system. State Banks showed a growing position in California banking, expanding to 33% of Total Capital of all banks in the state by 1964. The growth followed the same pattern for Total Resources, increasing from less than 20% in 1945 to over 32% in 1964. The great majority of both Capital and Resources was concentrated in a very few banks. Almost 80% of Capital and Resources were found in less than 8% of all the State Chartered Banks. The mix of deposits showed an aggressive shift from Demand Deposits to Time Deposits, with variations emerging in the three size-groups. The Capital Ratios (general measures of bank liquidity and safety) showed steady improvement for all groups over the twenty years. Allocation of Resources followed a general pattern of seeking the higher returns available, with interesting variations among the three groups. The examination of new banks being formed and others becoming extinct showed some interesting trends of small and medium-sized banks being formed, growing, and merging with other banks. Many areas were touched upon and questions raised to be answered in further studies that are recommended in the closing chapter of this thesis.

- Description:
- On the basis of the Rosen and Komorita findings demonstrating high correlations between Action Potential (AP) and Behavioural Criterion (BC), it was hypothesized that Ss who scored low, medium, and high on the AP index will also score low, medium, and high in their overt behaviour, respectively. Two hundred and eighty-four Ss from California State University (Northridge) participated in this study. Ss were classified as low, medium, and high on three assessed variables: (1) Action Potential(AP),(2) Internal-•External Scale (IE), and (3) Anomie Scale (A). The AP index consisted of measures of intention to act (I) and perceived effectiveness of act ion (E) and "was obtained by weighting each response to the I scale with the effectiveness rating for that item, and summing the product across all items." (Rosen and Komorita,1971, p.193). The IE scale as developed by Rotter, differentiates people who believe what happens to them is contingent on their own behaviour and those who feel that what happens to them is determined by chance or forces outside their control. Srole's A scale measures the individual's perception of social environment and his place in this environment.

- Description:
- At present there are many methods of psychotherapy. Freudian, Rogerian, Gestalt, Rolphing, Sensitivity Training, and many more approaches are designed mainly to delve into person self-awareness and help him do the same. Each approach uses its own definitions, techniques, and philosophy; however each requires a deep personal investment by the client. Often therapy is painful, supposedly indicating deep emotional gain. All too often people assume that emotional gain is dependent on pain. Thus many people only feel real insight if they are tormented or cry. I call this the "Thanks, I needed that, syndrome. I realize that this is all totally subjective, but to show that there is at least some validity in the above, I quote Frederick Pearls. In Gestalt therapy Verbatim, Pearls said, “To suffer one's death and to be reborn is not easy.” This metaphorically implies that mental health is dependent on emotional death accompanied by deep emotional pain. In light of the above statements, I would like to add another approach to the ones listed above, groups based on nonverbal communication. This is not sensitivity, or touch groups, but rather an educational approach designed as a complement to other approaches or as a basis for group interaction in and of itself. Before explaining my own philosophy, I would like to present some background information that was influential in the development of my philosophy. My approach is based on a child's early learning experiences. In the pre-school years a child develops skills for interpersonal interactions. Children also learn to evaluate and interpret their and other person's behaviors. An experiment by Bandura, as described by Mussen, indicated that children learn processes of self-evaluation and judgmental orientations from even brief exposure to models. Aside from learning these specific procedures, children also derive much motivation from their parents. Motivation directs them into socially accepted behaviors, and thus they learn to avoid the anxiety associated with parental disapproval. In addition, a child experiences anxiety when his own behavior is incongruent with social rules. By the second year, a child begins to inhibit his own behaviors and also chooses a subject with which to identify. Through identification the child learns gestures and behaviors needed for social interactions Thus, a child acquires a set of behaviors that he will use and modify for the rest of his life; he becomes socialized. Socialization includes methods of coping, identification, interpretation, and impression formation as well as personal and interpersonal behaviors and skills. Most of these skills require intricate use of nonverbal and verbal techniques. Non I will present a short treatment of nonverbal communication as a subject in and of itself. Many professions, such as acting, are directly based on nonverbal communication. Actors, salesmen, and everyone rely on nonverbal techniques seemingly instinctively to express attitudes and feelings. Are nonverbal cues instinctual or are they learned social behaviors? (See more in text.)

- Description:
- A questionnaire was administered to 131 teachers in sixteen elementary schools and six junior high and high schools in the Ventura Unified School District to determine whether instructional materials selected for individualized reading instruction were appropriate. Seventy six teachers responded from fourteen elementary and six secondary schools. Correlation of a pilot and final instrument yielded a Pearson Product-Moment Correlation Coefficient of .79. Statistical reliability approached the .80 level. Response scores were computed using a modified Likert scale progressing from five to zero. The answers were sought to three basic questions. These questions and the characterization of the means of the response scores for related items were: 1. Are decisions about instructional materials based on diagnosis? ("sometimes”) 2. Are the selected materials appropriate? ("often") 3. Are materials available in sufficient number and variety? (“usually”). Schools and grade levels were identified for which the characterization of the means of response scores was "seldom" for specified kinds of diagnostic tests. Schools were specified where a sufficiency of materials was characterized as being available less than “usually". Tests were identified which were most widely used and thought to be most valuable. Materials were identified which were used to implement individualized instruction based on diagnosis. Recommendations were made: l. That in-service training in individualized reading instruction be instituted. 2. That a District diagnostic procedure be established. 3. That diagnostic data be centrally processed and recommendations for individual students be provided for classroom teachers.4. That insufficiencies in materials be verified and immediately corrected.

- Description:
- This graduate project develops a method of analysis which determines the stability of high order nonlinear systems. The solution of the sets of differential equations of these high order nonlinear systems was accomplished by the use of a nonlinear analog model. This method of analysis uses no simplifying linearizations and hence yields results which are as accurate as the model describing the physical system. The results of the analog study are real-time trace solutions and are presented in the form of Stability Maps. Stabi1ity maps give a clear presentation of the relationship between the critical variables that govern the system; and thus yield a clear and simple method to make judgments en the effect of controllers on these systems. The design of a controller for a rocket engine combustion system was chosen as a motivating example to illustrate the method. This particular physical system was chosen since it is complex enough to fully illustrate the method. As in Liapunov's Methods, regions of stability for state variables are determined, except that this method gives the stability region which is largest in size. This ability to determine the complete region of stability gives this study a uniqueness not found in current methods of nonlinear analysis.
