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 …

Changing The Rules: Why The Current "Actual Knowledge" Sexual Harrasment Standard Doesn't Make The Cut In Athletics, Andrea Ivory

Vanderbilt Journal of Entertainment & Technology Law

In clear cases of sexual harassment, it is easy and appropriate to punish improper, predatory behavior. In such cases, the victim will be compelled to report the abuse, and the school will be compelled to respond. But the athletic environment occupies the blurry periphery of conduct that violates personhood. Here, in the sports context, intimate contact is routine, whether in heated moments on the field or in the forced companionship on the road. There is an increased risk of sexual harassment because the very environment is characterized by close physical and emotional relationships as well as unequal power relations. Physical …

Treasure Salvage And The United States Supreme Court: Issues Remaining After Brother Jonathan, John Paul Jones

Law Faculty Publications

On April 22, 1998, the United States Supreme Court announced its decision in California v. Deep Sea Research, Inc., 1 a case of shipwreck salvage begun as a maritime action in rem. Because the Court does not often accept cases of admiralty and maritime law, its decision was eagerly anticipated by American maritime lawyers and constitutionalists, both for what it might say about the Eleventh Amendment and sovereign immunity in a federal system and how it might limit Congressional power to alter the general maritime law and admiralty jurisdiction. Also anxious for the Court's decision were the few maritime lawyers …

An Analysis Of Physicians' Reluctance To Follow Terminally Ill Patients' Advance Directives, Norma Poirier

Harold L. Hodgkinson Award for Outstanding Dissertation

This explanatory study examined the reasons why physicians have difficulty respecting the wishes of terminally ill patients who refuse treatment. Consistent with the relevant literature, three alternative explanations were hypothesized in answering the question: fear of litigation, religious beliefs, and medical professional values.

Evidence was gathered from three different sources. Semistructured interviews were carried out with 24 emergency physicians from the Moncton Area in the Canadian province of New Brunswick and submitted to both quantitative and qualitative content analysis. Nineteen cases of terminally ill patients whose wishes not to be treated were not respected were collected and submitted to content …

The College Student Worry Questionnaire: Development And Preliminary Psychometric Properties, Gretchen M. Domek

Dissertations and Theses @ UNI

To date, there has not been a well-developed measure designed specifically to evaluate the content of worry. The purpose of this study was to examine the psychometric properties of a worry questionnaire designed to measure the worry content of college students, the College Student Worry Questionnaire (CSWQ). A total of 315 participants were recruited from several undergraduate psychology courses at a large mid-western university. Participants completed a questionnaire packet which consisted of a written informed consent form, a background questionnaire, the CSWQ, the Satisfaction With Life Scale, the Marlowe-Crowne Social Desirability Scale, the Positive and Negative Affect Schedule, the Beck …

Stability Of Paleosinks And Karstic Carbonates In The Southern Fire Clay Mining District Of Missouri, Robert Weiser Dillon

Doctoral Dissertations

"The Southern Fire Clay District of Missouri was intensely mined during the late-1800’s to mid-1900’s for its valuable resource of high refractory clays deposited within Pennsylvanian sinkholes “paleosinks”. Mining operations have produced modifications in the Ozark aquifer, which in effect has possibly increased the instability of this paleokarst terrain and the potential of further environmental impacts to the land. Evidence supporting this hypothesis are: (1) A southerly shift in the regional groundwater divide relative to the topographic divide. This possibly is caused by the distribution of leaking clay pits, which suggests that the bedrock permeability or hydraulic conductivity has been …

Facciones​: Fictional Identity And The Face In Borges’S “La Forma De La Espada.’, David Laraway

Faculty Publications

A SCAR, AS HOMER KNEW LONG AGO, is more than a distinguishing mark that permits one to be identified: it is the promise of a story to be told. Upon Odysseus's return to Ithaca, his old nurse Eurykleia, without yet recognizing her master, prepares to bathe his feet. Richmond Lattimore's translation renders the ensuing scene in these words: "Now Odysseus I was sitting close to the fire, but suddenly turned to the dark side; I for presently he thought in his heart that, as she handled him, / she might be aware of his scar, and all his story might …

Spin-Up In A Tank Induced By A Rotating Bluff Body, R. Daniel Maynes, J. Klewicki, P. Mcmurty

Faculty Publications

Spin-up of a turbulent flow in a cylindrical tank caused by a rotating bluff body has been investigated using flow visualization, fluid velocity measurements, and hydrodynamic torque measurements. During the spin-up process three distinct temporal regimes exist. These regimes are: (i) a build-up regime where the torque and the tangential velocity fluctuations in the close proximity of the body remain constant; (ii) a decay regime where these quantities decay with power-law relations; and (iii) a mean flow steady state where these values remain relatively constant. Experiments were conducted in two tanks differing in volume by a factor of 80 and …

Some Aspects Of The Adsorption Of A Lennard-Jones Gas On A Rough Surface, Douglas Henderson, Pawel Bryk, Stefan Sokolowski

Faculty Publications

We study the adsorption, including wetting, of a Lennard-Jones gas on a rough surface consisting of rough layer on a smooth substrate with which the gas interacts via a 9-3 potential. The rough layer is two molecular diameters thick and consists of a disordered quenched matrix of hard spheres. As well as interacting with the other matrix spheres by the hard-sphere potential, the matrix molecules interact with the gas molecules by the hard-sphere potential. Hence, on average, the degree to which the gas molecules can approach the substrate depends only on the density of the matrix layer. The density of …
