The Case Of Pearl S. Buck: Neglect And Abandonment Vs. Recognition And Recovery, Linda K. Adkins

Dissertations and Theses @ UNI

Pearls. Buck was the third American to win the Nobel Prize for Literature, the first American woman to win this Prize, and only the fourth woman in the world to do so. Taking into consideration the Nobel Prize and all the additional honors and awards Buck and her writing received, it is odd that she has been abandoned by American literary critics. Therefore, it is the goal of this thesis to identify reasons why Pearl Buck and her works have been neglected, and to provide significant reasons why she and her work should be recognized and studied. The first part …

Differential Effects Of Game Structure And Sociomoral Atmosphere On The Social Behaviors Of First Grade Students, Taunjah Patrease Bell

Dissertations and Theses @ UNI

Previous research has suggested that the structure of games influences children's social behaviors. However, no research to date has focused on the effects of both game structure and sociomoral atmosphere on children's social behaviors in the classroom. Thus, the purpose of the present study was to detennine the differential effects of game structure and sociomoral atmosphere on children's social behaviors during game time. Specifically, this study examined the differential effects of cooperative and competitive games on the cooperative, aggressive, disengaged and engaged onlooking behaviors of children in a constructivist and traditional classroom atmosphere.

With current demographic trends such as increasing longevity and increasing prevalence of chronic diseases, along with structural changes in medical care, the family (or more appropriately women), are called on to provide care to aging family members. Although current literature documents the situation of caregiving women, rarely are their voices heard and words included in pertinent analyses. This study is a qualitative and interpretive study using in-depth, semi-structured interviews with women and participant observation of caregiver support group meetings to understand, …

Gender, Religion, Causal Attributions, And Correctional Orientations Among Juvenile Justice Personnel, Amy Lynn Lyons

Dissertations and Theses @ UNI

The purpose of this quantitative study is to examine the attitudes and orientations of juvenile justice personnel from four urban counties within the state of Iowa. The nonrandom sample used in the present study is secondary and originally collected for a larger study conducted by Leiber (1993). A closed-ended, self-report survey was administered to each respondent. The total sample for the present research is 263. The hypotheses guiding the present study are based on the assumption that women experience religion differently from men, and in turn, will blame society for youth crime and favor orientations supporting diversion.

Sex, Violence, And Hand Puppets: History And Structure Of Punch And Judy Performance Tradition, James Robert Davis

Dissertations and Theses @ UNI

Punch and Judy are characters who exist only within the boundaries of the puppet theatre, in performances where characters are portrayed by inanimate figures. Nonetheless, the history of the puppet theatre, and particularly that of Punch and Judy, is closely related to the history of more widely accepted, actor-based theatre, where characters are portrayed by human beings. While the two traditions-share many common elements--such as the importance of characterization, direction, and design--the essential difference between actor-theatre and puppetry is the manner in which the performance is presented. The approach of this study is threefold: first, a linear history of the …

Physical Activity Patterns Among Physical Education Major Students In Selected Institutions Of China And The United States, Wei Bian

Dissertations and Theses @ UNI

The benefits associated with regular physical activity have been well documented in recent years. Numerous studies have investigated physical activity patterns among children, adolescents, and adults, yet little work to date has examined the patterns of habitual physical activity participation among pre-service physical education (PE) majors. Furthermore, inasmuch as physical activity affords health benefits irrespective of one's nationality or culture, comparisons among the peoples of nations around the world becomes of greater interest.

This study was designed to examine the leisure-time physical activity patterns of physical education major students in selected institutions from the People's Republic of China (PRC) and …

Pre-Performance Routines And Rhythm: A Comparative Study, Blake Wade Miller

Dissertations and Theses @ UNI

The present study was designed to investigate the effects of pre-performance routine rhythm on novel motor task success. At the center of the study was the comparison of differing characteristics of two theories of motor control: the dynamical systems theory and the schema theory. It was hypothesized that an even pre-performance routine rhythm would be more advantageous to task success than an uneven preperformance routine rhythm, regardless of the rhythmic characteristic of the task. The results concluded the contrary to be more accurate, and indicated that task success was more likely to occur when the pre-performance routine rhythm was congruent …

Factors That Influence Women’S Decision Regarding Hormone Replacement Therapy At Menopause, Judy Mixsell

Dissertations and Theses @ UNI

The purpose of this study was to describe factors that influence women's decision regarding hormone replacement therapy (HRT) at menopause. It is estimated that between 15 and 25% of eligible women are on HRT today. With all of the scientific evidence on the benefits of HR T, this percentage is very low. A questionnaire was sent to 420 randomly selected women from Black Hawk County ages 40 years and older. There were 161 usable responses for a 38.3% return rate. The majority of the women in the study were in the 40-60 years-old age group and were Caucasian college graduates. …

A Study Of Service Programs At Selected Midwest Universities, Tammy Lee

Dissertations and Theses @ UNI

When students enter a four-year college or university, they begin the journey of higher education. Through direct and indirect means of structured course work, involvement in campus organizations, and other activities, students gain the knowledge and skills crucial to obtaining a career in their chosen field. Although a college or university has primary responsibilities for the education of students, it also has a social obligation to the community in which it is located. One mechanism that has been devised to mutually benefit the students' need to develop as responsible citizens and the communities' need for college or university expertise is …

An Efficient Implementation Of The Transportation Problem, Alissa Michele Sustarsic

UNF Graduate Theses and Dissertations

The transportation problem is a special type of linear program in which the objective is to minimize the total cost of shipping a single commodity from a number of sources (m) to a number of destinations or sinks (n).

Because of the special structure of the transportation problem, a special algorithm can be designed to find an optimal solution efficiently. Due to the large amount of information in the problem, judicious storage and management of the data are essential requirements of any viable implementation of the transportation algorithm.

Using sparse matrix techniques to store the solution …

Robust I-Sample Analysis Of Means Type Randomization Tests For Variances, Anthony Joseph Bernard

UNF Graduate Theses and Dissertations

The advent of powerful computers has brought about the randomization technique for testing statistical hypotheses. Randomization tests are based on shuffles or rearrangements of the (combined) sample. Putting each of the I samples "in a bowl" forms the combined sample. Drawing samples "from the bowl" forms a shuffle. Shuffles can be made with or without replacement.

In this thesis, analysis of means type randomization tests will be presented to solve the homogeneity of variance problem. An advantage of these tests is that they allow the user to graphically present the results via a decision chart similar to a Shewhart control …

Deception In Interpersonal Settings: The Relationship Between The Content Of An Excuse And Its Recipient, Vera Margaret Trefry

UNF Graduate Theses and Dissertations

A correlational study investigated the nature of excuses, including the relationship of excuse complexity, uniqueness, frequency, and success to the level of knowledge the recipient has about the excuse giver. Analysis of results from responses of 121 participants to questionnaires describing excuses to employers, teachers, parents, and spouse/boy/girlfriends found that the complexity and uniqueness of excuses vary positively with the knowledge level of the recipient, but only when an unequal power relationship exists between the recipient and the excuse giver. Excuses to recipients with a low personal knowledge level of the excuse giver, such as employers or teachers, tended to …

Conjoint Behavioral Consultation: How Effective Is Cbc With Ethnic Minorities, Tina L. Hoffman

Dissertations and Theses @ UNI

The literature over the past decade has provided evidence of the positive relationship between home-school collaboration and student success. Yet such educational partnerships are not as common as they should be, particularly among minority families and their schools. Empirical evidence of effective, culturally sensitive, homeschool partnership models focused on the individual-child level of collaboration is virtually absent in the literature. Conjoint Behavioral Consultation (CBC) is one model of home-school collaboration at the individual child level. CBC represents an expansion of traditional behavioral consultation. In CBC both parents and teachers serve as joint consultees to provide a more holistic view of …

The Architecture Of Privacy: Remaking Privacy In Cyberspace, Lawrence Lessig

Vanderbilt Journal of Entertainment & Technology Law

This is an essay about privacy. My aim is to understand privacy through these two very different ideas. Privacy, in the sense that I mean here, can be described by these two different ideas. It stands in competition with these ideas. It is that part of life that is left after one subtracts, as it were, the monitored and the searchable. A life where less is monitored is a life where more is private; and life where less can (legally or technologically) be searched is also a life where more is private. By understanding the technologies of these two different …

Phoenix Rising: Inside The Owner's Box With Counsel To Jerry Colangelo, J. S. Ruffner

Vanderbilt Journal of Entertainment & Technology Law

In late spring of 1987, I received a telephone call that changed my law practice. Jerry Colangelo, General Manager of the Suns since its arrival in Phoenix as an expansion NBA franchise in 1969, called me to discuss representing a group of investors he was putting together for the purchase of the franchise. At the time, the Suns franchise was the only major professional sports team in Arizona and had been very successful. Unfortunately, the reputation of the team, carefully nurtured from its arrival, recently had been tarnished by allegations and investigations concerning drugs. Jerry explained that the Tucson and …
