If f is analytic in a neighborhood of ∂D = {z| |z|= 1} and if K = f(∂D), then C-K has only finitely many components; moreover, if U is a bounded simply connected region of the plane, then ∂U = U_j=0<sup>n</sup r_j where each r_j is a rectifiable Jordan curve and r_i ∩ r_j is a finite set whenever i ≠ j. Let μ be a positive regular Borel measure supported on ∂D and let m denote normalized Lebesgue measure on ∂D. If L is a compact set such that ∂L ⊂ K and R(L) is a Dirichlet algebra and if ν = μof⁻¹, then the Lebesgue decomposition of ν|_∂V with respect to harmonic measure for L is ν|_∂V = μ_aof⁻¹|_∂V + μ_sof⁻¹|_∂V where V = intL and μ = μ_a + μ_s is the Lebesgue decomposition of μ with respect to m. Applying Sarason’s process, we obtain P^∞(ν) ≠ L^∞(ν) if, and only if there is a Jordan curve r contained in K such that mof⁻¹|_Γ << μ_aof⁻¹|_Γ. If U is a unitary operator with scalar-valued spectral measure μ then f(U) is non-reductive if and only if there is a Jordan curve r ⊂ K such that mof⁻¹|_Γ << μ_aof⁻¹|_Γ. Let G be a bounded region of the plane and B(H) the algebra of bounded operators in the separable Hilbert space H. If π: H^∞(G)→B(H) is a norm-continuous homomorphism such that π(1) = 1 and π(z) is pure subnormal then π is weak-star, weak-star continuous. Moreover, if S is a pure subnormal contraction, the S^*n→0 sot. / Ph. D.

Family characteristics, and their typologies were examined in relationship to family adaptation in 97 nonclinical families with adolescents. Cohesion, adaptability, and satisfaction were measured by Family Adaptability and Cohesion Evaluation Scales III. Quantity of family time and routines and value of family time and routines were assessed using an adapted version of the Family Time and Routines Index. The dependent variable, family adaptation, was obtained using the Family Member Wellbeing Index. Neither the Rhythmic Typology nor the Balanced Typology had significant differences in family across typology groups. Multiple regression analyses showed that the only family characteristic that explained variance in family adaptation was family satisfaction (Beta=.22, p <.05). The results suggest that it may be too simplistic to expect family characteristics or typologies alone to explain variance in family adaptation. The characteristics need to be examined in conjunction with stress theory variables. / Master of Science

Under the conditions of this study, the following conclusions seemed justified: 1. Cud inoculations did not improve rate of growth or efficiency of feed utilization in calves through four months of age. Consumption of hay was not materially increased by cud inoculations. 2. Thus. it is concluded that cud inoculation is of no economic value under practical calf raising conditions. 3. Calves restricted in grain feeding did consume more hay than unrestricted calves; however, the increase was not great. Efficiency of feed utilization, as measured by the pounds of T. D. N. consumed per pound of gain was essentially the same for calves on a grain:hay ratio of 1:2 (restricted grain feeding) as those on a 1:1 grain:hay ratio (unrestricted grain feeding). 4. Skeletal growth, as determined by height at withers, was adversely affected by restriction or grain in the feeding program. 5. Calves fed one pound of whole milk per ten pounds of body weight daily up to 60 days of age, and a simple grain ration made satisfactory growth when grain was fed free choice (with a four-pound daily maximum) and hay of average or better quality was fed free choice. 6. Thus, it is indicated that a substantial monetary saving in the raising of herd replacements may be affected by the use of a simple grain ration instead of high-priced commercial calf mixtures. / Master of Science

A long-term project was initiated in order to stuq the et!ecta of sawdust Jlltll.ch and two .forms of a synthetic soil conditioner on the yield of vegetable crops. Data is in this thesis concerning experimental results of two years, 1953 and 1954. In addition, a report is given on a preliminary study which was conducted in 1952. In general, not enough research has been done on this project to formulate definite conclusions. However, certain tr.nds are apparent: 1. The soil treatments have caused no significant changes in the pH values of the soil. 2. The treatments have caused no wide fluctuations in the amounts of calcium, magnesium, phosphoric acid, or potash in the soil. 3. The potassium dichromate and sulphuric acid tests, used by the Soils Laboratory of this institution, did not indicate that the soil treatments increased the organic matter content of the soil. 4. In general, synthetic soil conditioners as used in this test have produced no significant effects. 5. Incorporation of sawdust into the soil mq result in nitrate deficiency. However, this deficiency can be readily corrected by the addition or fertilizers containing nitrogen. 6. Sawdust mulch has, in general, benefitted the production of vegetable crops. The beneficial effects are probably caused by conservation of soil moisture (including an increase in the percentage of moisture available to plants), and by reduction of soil temperature fluctuations. / Master of Science

The problem explored in this study was the effectiveness of a community leadership development program in training identified emerging community leaders to develop networks of communication and understanding between the governmental, economic, and educational elements of the city and to use these contacts in community organizations that address the problems of the city. Attention was given to what networks were in place before, during, and after a short leadership program. Contact type was addressed. Secondly, the study analyzed the use of network structure by participants in community organizations. The association of race and gender was considered. Finally, the use of network analysis as a method of evaluating the outcomes of a community leadership program was researched. Findings on interpersonal contacts were similar in four classes. Prior to the program contacts were minimal. By June 1984 contacts among participants in all four classes increased from a range of 70% to 392%. Another finding was that contacts among participants prior to the program were with those of the same race. Contacts changed during and after the class. By June 1984 black participants In three of the four classes surveyed had more contacts with whites than with blacks. White participants continued to have most contacts with whites. Race seems to be a more important factor In the selection and maintenance of contact than does gender. These findings were generally borne out by LMR II Interviews who said that the networking process with persons of a different race, gender, and residence was the single most important outcome of the program. Findings on contact type suggest that gender is more important than race In contact type. Black females' contacts with fellow participants were usually work contacts; male contacts were community contacts. Neither race nor gender was significant in community organizational memberships of participants. However, participant memberships shifted busIness/professional memberships to civic/ government memberships, a desired program outcome, in three out of four classes. Black females joined more political/government organizations both before and after the program as well as business/ professional organizations. White females, on the other hand, joined more civic/community organizations and black males joined more educational/religious organizations. Program outcomes suggest that the leadership development model of Leadership Metro Richmond seems to be an appropriate model to bring about the desired outcomes of the program. / Ed.

The problem for this study was to identify standards desirable for faculty when four-year hospitality management education programs are accredited. A modified Delphi technique was used to determine standards and reach agreement among a panel of hospitality professionals concerning desirable standards to be used to evaluate faculty during the self-study section of the specialized accreditation process. Nine faculty qualifications identified in the literature as being common to the self-study section of specialized accreditation constituted the framework of the study. These qualifications included academic preparation, scholarly productivity, applied professional experience, involvement in professional associations, competency in area of specialization, teaching effectiveness, interest in curricular experimentation, ability to work with students, and public service. A professional panel consisting of 15 hospitality management education administrators/faculty and 12 hospitality management industry representatives developed standards for each of the above qualifications. The panel rated the desirability of the standards using a Likert-type scale (4=very desirable, 3=desirable, 2=undesirable, l=very undesirable). All standards receiving a total of two-thirds of the responding panel members' votes in the very desirable and desirable categories were included in a proposed accreditation model of faculty standards. Unexpectedly, the panel questioned the inclusion of the qualification of public service and agreed to omit the evaluation of faculty on this qualification during specialized accreditation. It was recommended that eight of the qualifications and their corresponding standards be used by The Council on Hotel Restaurant and Institutional Education (CHRIE) to form criteria necessary for the self-study section of specialized accreditation. It was also recommended that the developed standards be used by hospitality management faculty as a means of self-evaluation. Finally, it was recommended that hospitality management education administrators use the standards as (a) guidelines when hiring and evaluating faculty and (b) a means for assessing faculty needs prior to faculty development programs. / Ed.

Methods designed to improve the practicality of the elliptical-core two-mode optical fiber sensors for use in real-life applications are presented. The improvements include the development of insensitive lead fibers and an optical device which allows fringe counting at the output of the sensor. The insensitive leads eliminate extraneous perturbations and effectively isolate the sensing region. The fringe counting optics are designed to generate quadrature-phase shifted signals, thereby allowing the determination of whether the strain is increasing or decreasing. Work performed to advance the understanding of the effect of sensor placement within a composite specimen is also presented. Optical fiber sensors are embedded between different laminae of a graphite-epoxy composite panel, and the outputs of the sensors are shown to be proportional to the distance of the sensor from the neutral axis. / Master of Science
