The Relationship Between Self-Actualization and Aspects of Female Sexuality

Paxton, Anne 01 May 1976 (has links)
The study reported examined the relationship between self-actualization and aspects of female sexuality. Ninety-five white, single female undergraduates from a regional Southeastern state university volunteered to serve as subjects. Three questionnaires were administered to the subjects: the Personal Orientation Inventory (POI), Eysenck’s Inventory of Attitudes to Sex, and a two-item religiosity measure. The data were analyzed via correlation and hierarchical multiple regression analysis. The results indicated that when the effects of the covariates were controlled, there was a significant relationship between self-actualization and sexual permissiveness, sexual satisfaction and prudishness. Although self-actualization and sexual libido were significantly correlated, after the effects of the covariates were controlled, self-actualization did not account for a significant portion of the variance in sexual libido. The importance of controlling for extraneous variables when examining the relationship between self-actualization and sexual attitudes is stressed. Implications for future research include using different populations to investigate the relationship between self-actualization and sexual attitudes, using different measures of self-actualization to investigate its relationship to sexual attitudes, and examining the relationship between self-actualization and other aspects of sexuality.

A Study of Ylide Extractions of Mercury in Fish and Water Using Cold Vapor Flameless Atomic Absorption Techniques

Vail, Howard 01 January 1980 (has links)
Cold vapor flameless atomic absorption spectrophotometry is an analytical method used in the determination of mercury. Its sensitivity is less than one part per billion using a 100 milliliter sample, and there are virtually no interferences from other metal ions. The method is best carried out making use of a permanganate-persulfate oxidation step with heat. The ylide, triphenylphosphoniumcyclopentadienylide (CpPPh3), which extracts mercury almost quantitatively from water, was used in attempts to remove mercury from exposed goldfish. Though not toxic to the fish, CpPPh3 did not significantly lower mercury levels. Evaluation of CpPPh3 as a possible phase transfer catalyst failed to identify a true catalytic species.

Some Aspects of the Ecology of Larval Fishes in Rough River Lake, Kentucky

Kindschi, Greg Allen 01 May 1979 (has links)
In Rough River Lake, Kentucky, some aspects of the ecology of larval and juvenile fishes were investigated from April – August, 1978. Larval fishes were collected weekly from the upper reaches of the lake from the surface and bottom, during daylight and dark periods. Twenty-three species and three categories of unknown larval and juvenile fishes, represented by 177,119 individuals, were collected. White bass and logperch larvae were the first to appear on April 15 with surface water temperatures of 18.5 C. Gizzard shad larvae dominated net collection while Lepomis spp. were the second most abundant. Larvae were primarily concentrated near the surface and taken mostly at night. Larval concentrations were greatest on May 30. Throughout the study, most specimens were collected along the shorelines. Growth rates of most taxa generally lagged early in life but increased greatly after the first 6-8 weeks. Light traps proved to be an effective method of capture for certain species. Piscivory was observed in white bass 10.5 – 25 mm total length on gizzard shad, and logperch 16.5 – 17 mm total length on unknown larvae and suckers.

The Social Construction of Professional Knowledge Illustrative Empirical Patterns in Social Work, 1956-1973

Jorgensen, Danny L. 01 July 1974 (has links)
Traditional sociological conceptions of professions are examined in this thesis by refocusing attention upon knowledge and ideology as a key to understanding changes in professional reality and action. In a proposed transcending model of professional knowledge it is hypothesized that conflicts between certain ideological positions will result in the displacement of one position by an opposing position and thereby produce changes in the definition and meaning of specific aspects of professional knowledge. Furthermore, it is suggested that knowledge construction, ideological debate, and changes in professional meaning may be observed in the arena of professional communication which is represented by major professional journals in a field. Using the field of social work as a test case for this study, a content analysis design is employed to examine population of 778 journal articles appearing in this field’s major journal publication, Social Work, from 1956 through 1973. The results of this analysis indicate the presence of six identifiable ideological positions in social work knowledge. Three pairs of these ideological positions were found to conflict and vary inversely with each other between 1956 and 1974, and thereby illustrate three unique temporal patterns of ideological conflict and debate. Another set of ideological positions were found to be positively associated together and vary inversely with an opposing constellation of ideological claims. In general, these findings support the proposed transcending model and evidence a relatively radical change in the defined meaning of social work from 1956 through 1973. Several possible interpretations of these findings are explored from the perspective of traditional sociological conceptions of professions and the proposed transcending model. The favored interpretation suggests that the normative view of the professions is outdated by recent changes in professional meaning, and that a processual conception of the professions and their operation as dynamic and competitive is a more accurate and useful theoretical model of professions, their reality, and their change. Implication of the results of this study for social service fields are explored and in conclusion certain suggestions are made for needed future inquiry into professional knowledge and related topics raised by this thesis.

Determination of (n, 2n) Reaction Isomeric Cross Section for 87Rb, 112Cd, 138Bz, and 186W Using 14 MeV Neutrons

Kao, Hsiao-Chueh 01 August 1973 (has links)
The purpose of this investigation was to measure the cross section for each of the reactions 87Rb(n, 2n) 86mRb, 112Cd(n, 2n)111mCd, 138Ba(n, 2n) 137mBa and 186W(n, 2n) 185mW at 14.7 ± 0.03 MeV incident neutron energy. The incident neutron flux was determined during each irradiation from the activity produced in copper or aluminum disks between which the isotopically enriched sample was sandwiched. The 63Cu(n, 2n)62Cu and 27Al(n, p)27Mg reaction cross sections were assumed to be 593 ± 45 mb and 73 ± 5 mb respectively. The activity of the sample and monitors was determined by using a 7.6 cm x 7.6 cm NaI(Tl) scintillation spectrometer calibrated with NBS standard sources or by employing the coincidence method in the case of the copper monitors. The measured cross sections in this experiment were 87Rb(n, 2n)86mRb (450 ±51 mb), 112CD(n, 2n)111mCd (400 ± 45 mb), 138Ba(n, 2n) 137mBa (769 ± 87 mb), and 186W(n, 2n)185mW (602 ± 74 mb).

Impact of Several Chemical and Physical Properties of Two H-Coal Recycle Solvent Streams on Their Relative Solvent Quality

Collins, Joe 01 August 1984 (has links)
The purpose of this study was to follow the solvent quality curve of the recycle solvent streams of the H-Coal Pilot Plant run by Ashland Petroleum Company at Catlettsburg, Kentucky. This was done with the use of a microautoclave (shaker-bomb liquefaction unit). Several physical and chemical properties of these recycle oils were determined, and these values were correlated with the observed solvent quality. It is shown that the relative, solvent quality of these recycle oils correlate well with many of the chemical and some of the physical properties determined in this study.

Work Decrement and Facilitation of Performance as a Function of the Accuracy of Mental Imagery

Turner, Maxwell 01 September 1982 (has links)
The purpose of this study is twofold: to determine the relationship between accuracy of the image and work decrement and to investigate the relationship between accuracy of the image and facilitation of performance. A total of 36 right-handed undergraduates were tested on the rotor pursuit operating at 45 rpm and asked to imagine themselves actually tracking the target with the stylus. During the imagery trials the subjects verbalized the word “top” each time their image made one complete revolution. Each subject engaged in a 9 30-sec imagery trials which were followed by either an 8-sec rest and then 9 30-sec performance trials (no-rest condition) or a 5-min rest and then 9 30-sec performance trials (rest condition). Each subject attended two sessions seven days apart. During the first session the subjects received either the rest or no-rest condition, and during the second session the subject received the other condition. The order in which the rest and no-rest conditions were administered was counterbalanced across subjects so that half received the rest condition first while the other half received the no-rest condition first. Accuracy of the image was measured by the number of “tops” the subject verbalized during each 30-sec imagery trial. Performance was measured by the total time the subjects kept the stylus over the rotating target during each 30-sec performance trial. A regression analysis showed that accuracy of the image predicted overall performance. This finding supports previous research which indicates that performance increases as the similarity of practice and criterion tasks increases. A second regression revealed that accuracy of the image, for under imagers and accurate imagers, did not predict work decrement. This outcome supports White’s (1981) results that under and accurate imagers accumulate equivalent amounts of work decrement. Finally, the author discusses a possible mechanism involved in producing the apparently equal levels of work decrement for both under and accurate imagers. It is speculated that perhaps the apparent level of work decrement for those who under image is exaggerated by an abrupt change in information density.

A Study of the Holding Power and Follow-Up of North Bullitt High School Students (Classes of 1978, 1979 and 1980)

Wagoner, Robert 01 December 1981 (has links)
Data concerning the Classes of 1978, 1979 and 1980 from North Bullitt High School, the Bullitt County School System and the State of Kentucky were compared to determine the holding power, survival rates and whereabouts of graduates. The comparison of data concerning holding power and survival rates showed that North Bullitt High School compared favorably with both the Bullitt County School System and the State of Kentucky. The data showed that for the three year period from 1978 to 1980 the holding power of North Bullitt High School increased while the holding power of both the Bullitt County School System and the State of Kentucky decreased. The comparison of data concerning the whereabouts of graduates showed that North Bullitt High School compared favorably with the Bullitt County School System and the State of Kentucky in all but one area. The data showed that the State of Kentucky had a significantly higher percentage of graduates who planned to attend college than either North Bullitt High School or the Bullitt County School System. The comparison of data concerning the whereabouts of North Bullitt High School’s 1978, 1979 and 1980 graduates showed a significant differences between what the graduates anticipated doing after leaving school and what the graduates are actually doing.

Population Dynamics and Tackle Catch Susceptibility of the Smallmouth Buffalo, Ictiobus Bubalus (Rafinesque), in Rough River Lake, Kentucky

Waite, Alan 01 May 1976 (has links)
The population of the smallmouth buffalo, Ictiobus bubalus (Rafinesque), was studied in Rough River Lake, Kentucky, from July, 1974, through June, 1975. A total of 758 individuals were collected with 587 being marked and returned. From calculations made using poison population sample data, population size was estimated to be between 150,00 to 225,000 adult fish or 29 to 44 fish per acre. Scales were studied to determine age and through back calculation, the total length of each fish at the time of each annulus formation determined. Ten year ciasses were observed with the majority of the fish in age groups IV and V. Eighty percent of all fish taken in the study ranged from 400 to 550 mm total length. Age groups III through VIII were represented in this 150 mm size range. Only two age group II fish were collected with no individuals less than two years old represented. Condition or plumpness was greatest in smaller fish and decreased as the length of the fish increased. During the month of April, fish moved upstream to spawn, at which time catch success per fishing effort was greatest. Flag nets of 2 ½- and 3-inch mesh sizes were the most efficient tackle. Gill nets followed in order in catch success with the trammel and hoop nets catching very little throughout the year. Fish 400 to 550 mm in length were seldom caught in 4-inch mesh nets, which is the state legal minimum size for commercial tackle in Kentucky. The large percentage of the population ranging from 400 to 550 mm total length, representing a non-harvestable size range, indicated an overpopulation of slow growing smallmouth buffalo.
