The Development of a Psychobiologic Profile of Individuals Who Experience and Those Who Do Not Experience Exercise-Related Mood-Enhancement (open access)

The Development of a Psychobiologic Profile of Individuals Who Experience and Those Who Do Not Experience Exercise-Related Mood-Enhancement

The present investigation involved the development of a psychobiologic profile of individuals who experience exercise-related mood-enhancement and those who do not. The sample (N=301) consisted of students participating in 10-week exercise classes at North Texas State University. All subjects completed pre-test inventories assessing various psychological (i.e., trait anxiety and depression, attitude toward physical activity, self-estimation of physical ability and attraction to physical activity, expectancies of health benefits from exercise, and self-motivation) and biological (i.e., aerobic capacity and body fat percentage) variables. Trait anxiety and depression were also assessed before and after the 10-week exercise program and state anxiety and depression were assessed on an acute basis on two separate occasions during the program. Multivariate analysis of variance and discriminant function analysis were employed to determine which variables maximally discriminated between individuals who experienced mood-elevations following exercise and those who did not enjoy such rewards. The hypothesis that these two groups of individuals differ significantly from each other was not upheld by the results; thus, an overall psychobiologic profile could not be developed. However, the data did reveal that individuals who held a more positive attitude toward physical activity for the purpose of health and fitness reduced their state anxiety and …

A Monte Carlo Analysis of Experimentwise and Comparisonwise Type I Error Rate of Six Specified Multiple Comparison Procedures When Applied to Small k's and Equal and Unequal Sample Sizes (open access)

A Monte Carlo Analysis of Experimentwise and Comparisonwise Type I Error Rate of Six Specified Multiple Comparison Procedures When Applied to Small k's and Equal and Unequal Sample Sizes

The problem of this study was to determine the differences in experimentwise and comparisonwise Type I error rate among six multiple comparison procedures when applied to twenty-eight combinations of normally distributed data. These were the Least Significant Difference, the Fisher-protected Least Significant Difference, the Student Newman-Keuls Test, the Duncan Multiple Range Test, the Tukey Honestly Significant Difference, and the Scheffe Significant Difference. The Spjøtvoll-Stoline and Tukey—Kramer HSD modifications were used for unequal n conditions. A Monte Carlo simulation was used for twenty-eight combinations of k and n. The scores were normally distributed (µ=100; σ=10). Specified multiple comparison procedures were applied under two conditions: (a) all experiments and (b) experiments in which the F-ratio was significant (0.05). Error counts were maintained over 1000 repetitions. The FLSD held experimentwise Type I error rate to nominal alpha for the complete null hypothesis. The FLSD was more sensitive to sample mean differences than the HSD while protecting against experimentwise error. The unprotected LSD was the only procedure to yield comparisonwise Type I error rate at nominal alpha. The SNK and MRT error rates fell between the FLSD and HSD rates. The SSD error rate was the most conservative. Use of the harmonic mean of …

The Symptoms of Childhood Depression as Factors in Children's Reading Difficulties (open access)

The Symptoms of Childhood Depression as Factors in Children's Reading Difficulties

The purpose of this study was to investigate symptoms of childhood depression as factors in elementary school age children's reading difficulties. Subjects for study included children who evidenced symptoms of depression from among those referred to the Pupil Appraisal Center (PAC) at North Texas State University for reading difficulties between October, 1983, and April, 1985. The Weinberg Affective Scale (WAS), a screening device for childhood depression, was used to identify the subjects for this study. Using document analysis as the research approach, the researcher examined, recorded, and categorized referral and evaluation statements made by parents, teachers, counselors, and reading specialists the subjects1 PAC files that described symptoms of childhood depression. Also analyzed were diagnostic test data from the evaluation reports of PAC counselors and reading specialists.

An Historical Inquiry Into the Development of Higher Education in Ghana 1948-1984: a Study of the Major Factors That Have Controlled and Inhibited the Development of the Universities of Ghana (open access)

An Historical Inquiry Into the Development of Higher Education in Ghana 1948-1984: a Study of the Major Factors That Have Controlled and Inhibited the Development of the Universities of Ghana

Universities in many industrialized countries including Japan, and Australia, have enabled those countries to achieve rapid economic and social advancement. However, this is untrue for the universities of Ghana, due to the country's ailing economy, its continued dependence on foreign manpower, aid, and material goods. The purpose of this study, therefore, was to illuminate the major factors and events that have controlled and inhibited the development of higher education in Ghana from 1948 to 1984. The method of acquiring data involved a computer and manual search for documents from 1) ERIC Database, 2) libraries , and 3) Embassy of Ghana, Washington, D.C. The findings include (1) Establishment of universities on the basis of the Asquith Doctrine; (2) Imitation of British universities' curriculum, constitution, standards and social functions; (3) Characterization of universities by elitism, lack of diversity and adaptation, autonomy, excellence and narrow specialism in their honor degree programs; (4) Emphasis on cognitive rather than psychomotor learning; (5) Matriculation of inadequately qualified secondary school science students; (6) Absence of a nationally formulated statement of manpower needs, goals, and effective long-term planning; (7) Financial exigencies; (8) Suppression, perversion and abuse of academic and intellectual freedom by the government and universities; (9) Inconsistent …

The Prevalence of Specific Learning Disabilities in School-Aged Hearing Impaired Children (open access)

The Prevalence of Specific Learning Disabilities in School-Aged Hearing Impaired Children

The purpose of this investigation was to determine the prevalence of specific learning disabilities in school-aged hearing impaired children based on the proposed theoretical definition of the National Joint Committee for Learning Disabilities (1981) and the theoretical definition constructed by the Canadian Association for Children and Adults with Learning Disabilities (1981). The operationalization of these theoretical definitions, coupled with the current operational definition issued by the Texas Education Agency (1983), formulated the investigative framework.

Interactional Patterns in Families of Patients with Breast Cancer (open access)

Interactional Patterns in Families of Patients with Breast Cancer

This study utilized ethnographic methodology to describe the communicative interactional patterns in families with a member who has breast cancer. Three breast cancer patients whose families were between the adolescent and launching of children developmental lifestage (McGoldrick & Carter, 1982) were chosen for the study. Data were collected from a series of three interview sessions over a period of four weeks with a two week time lapse between each of the interview sessions. Interview sessions were conducted in the families' homes by the researcher. All interviews were video and audio tape recorded for the purpose of preserving data for transcribing and coding. Research questions examined individual perception of meaning in regard to the disease, the structure and organization of the family in relation to the illness, and the effects of family communicative interaction on the course and management of the disease. Findings indicated that family members' responses to the diagnosis of "breast cancer were influenced by multi-generational "beliefs. All three families formulated a collective belief which supported the mother's belief about the disease. Each of the three families were mother-centered, and each mother seemed to use a metacommunicative approach to mediating family transactions. Each of the three fathers were reported …
