<p>This study examines L.P. Hartley's male protagonists who provide the focus for his major fiction. The male characters' difficulties in understanding themselves, and the world which confronts them, are issues discussed by the few serious critics of Hartley's work. The book-length criticism, however, has tended to rely heavily upon figures like Freud and Jung, and upon Romantic and Judaeo-Christian thinking and symbolism, in order to establish its views. My study constitutes an attempt to avoid the overt application of "schools" to Hartley's work, although like Hartley himself I cannot claim to have been completely untainted, for example, by our Freudian climate. Specifically, I am interested in demonstrating the complex processes by which Hartley's sensitive male protagonists near self-understanding, and how Hartley uses detailed, even intricate, symbolism to express those developments.</p> <p>Using the Eustace and Hilda trilogy, I thoroughly examine Eustace Cherrington's growth toward self-understanding in order to demonstrate the special problems confronted by a typical Hartleian male. Leo Colston, in The Go-Between, and Stephen Leadbitter, in The Hireling, are then included in the discussion, and the three males' associations with fantasy worlds, and with manipulative women, are seen to contribute to the difficulties faced by these protagonists. In a final chapter, by examining the earlier fiction in the light of some of Hartley's less symbolic later novels, in particular The Harness Room, I indicate how Hartley's symbolism has been used, in the past, to conceal his interest in male homosexual relationships.</p> <p>Hartley, in addressing the issue of self-knowledge in his fiction, also makes a statement concerning the difficulty faced by the individual who, after the Second World War, was especially confronted with the task of securing an identity for himself in an increasingly egalitarian, fast-paced "modern" world. Hartley's canon is a metaphoric expression of how what Hartley terms the "Great Man" of Victorian fiction becomes the weak, victimised, but in many ways "greater" twentieth century man; for all his insecurity and failure, the Hartleian male of the 1970's is one who has painfully explored both himself and his environment in an attempt to survive, and to establish for himself, however temporarily, a "unique personality" appropriate to his time.</p> / Thesis / Doctor of Philosophy (PhD)

The current study evaluated the potentially detrimental effects of daily resistance training on cardiovascular health using a longitudinal study design. This study also addressed the effects of resistance training on vascular endothelial function. Recent cross-sectional studies have shown resistance trained individuals have reduced whole-body arterial compliance compared to sedentary controls and that the age-associated reduction of arterial compliance is augmented in resistance trained athletes. The effect of resistance training on vascular endothelial function has not been addressed to date in the literature. Twenty-eight young healthy males (age: 23±3.9 [mean±SD]) were whole body resistance trained five times a week for twelve weeks, using a split body design. Measurements of supine resting arterial blood pressure at the brachial artery, carotid, brachial and femoral cross-sectional compliance, and brachial vascular endothelial function (using flow-mediated dilation) were acquired prior to, halfway through and following the exercise training protocol. Strength of various body segments increased significantly following the resistance training program. Shoulder press one repetition maximum (1RM) lifts increased from 141.4±7.6 lbs. to 185.2±8.8 lbs. and double leg press 1RM from 483.0±29.0 lbs. to 859.8±52.1 lbs. Resting diastolic blood pressure increased significantly from Mid to Post training (61.8±1.3 mmHg to 65.4±1.2 mmHg) yet was not significantly changed from Pre values (62.9±1.2 mmHg). Pulse pressure was reduced significantly with exercise training by the Post training time-point (Pre 63.3±1.9 mmHg; Mid 59.0±2.4 mmHg; Post 53.7±2.8 mmHg). Mean arterial carotid and femoral artery diameters were not changed with resistance training; however, mean brachial artery diameter increased by the Mid training time-point and remained elevated at the Post training time-point (Pre 3.81±0.10 mm; Mid 4.03±0.1 0 mm; Post 4.04±0.11 mm). Cross-sectional compliance did not change at the carotid or the brachial arteries, however the femoral artery experienced a reduction of compliance by the Mid time-point that remained to the Post training time-point (Pre 0.162±0.012 mm²/mmHg; 0.125±0.013 mm²/mmHg; Post 0.129±0.015 mm²/mmHg). Brachial vascular endothelial function measured using flow-mediated dilation did not show a significant change with resistance training. When normalized for shear rate (which was also unaltered with resistance training) there were no changes in endothelial function. Peak and 1 0-s average brachial post-occlusion blood flow was enhanced with resistance training (Pre 247.5±14.0 ml/min; Mid 331.1±18.5 ml/min; Post 290.5±21.0 ml/min) possibly revealing enhanced resistance vessel function. In conclusion, resistance exercise training results decreased PP, reduced femoral compliance, an increase in mean brachial artery diameter and enhanced post-ischemic blood flow. The exact mechanisms responsible for such changes remain unknown and require further investigation. / Thesis / Master of Science (MS)

Grounded theory methods of Strauss and Corbin (1990) and multidimensional scaling techniques (Kruskal & Wish, 1991) were used in this investigation to study the factors that influence a woman's choice to remain in or to leave a male-dominated major (Zuckerman, 1981). Focus group interviews were conducted with 62 sophomore women who had originally chosen male-dominated majors as freshmen to gain insight into the meanings and motivations of the student decisions. The participants responded to a 25-item survey which yielded a-three dimension solution with five clusters in the multidimensional scaling analysis. Five themes emerged from the focus groups as factors influencing a woman's choice to remain in or to leave a male-dominated major: (a) self confidence and refuse to lose attitude; (b) interest in the field; (c) career goals, jobs, and money; (d) ability and experience in the field; and (e) the desire to make a difference. The three dimensions were (a) time of experience, (b) motivation, and (c) career rewards. The five clusters were: (a) pre-college experiences, (b) college experiences, (c) career rewards, (d) self-confidence, and (e) self-fulfillment. The findings are consistent with current literature; however, the use of the multidimensional procedure goes further and helps to explain some of the motivations of the students and challenges some of the beliefs that persons in the practice of student affairs profess about woman and chilly climate. The study extends knowledge about how women deal with their chilly environment. / Ph. D.
