While the word “pedagogue” may evoke a vision of an instructor who is dogmatic and set in his own ways, the word descends from Greek origins: ped “child” + agogos “leader.” A pedagogue is, by definition, literally the servant who escorts the child to and from school – the “pedagogue” accompanies the student on the journey for knowledge. True to this definition, Douglas Campbell is model pedagogue – one who gently guided his countless students throughout their musical journeys. As Professor of Music (Horn) at Michigan State University for 45 years, and Horn Instructor at Interlochen Arts Camp for 25 years, Campbell was a significant influence on many developing hornists. Following their study with him, Campbell's students eventually won orchestral and college teaching positions across the United States and throughout the world. Having influenced an extraordinary number of horn students during his tenures at Michigan State University and Interlochen Arts Camp, Douglas Campbell's life and career serve as an excellent example of contemporary horn pedagogy in the United States. This dissertation provides a detailed biography of Douglas Campbell and provides evidence of his contributions to American horn pedagogy, while documenting Campbell’s performing career with the Richards Quintet, which toured the United States, Canada, and China. Additionally, compositions written for or commissioned by Campbell (Harmonielehre: Variations for Solo Horn [1996] and Epitaph [2012]) are discussed, to illustrate Campbell's influence on solo literature for the horn.

Thesis (M.A.)--University of Montana--Missoula, 2007. / Title from PDF title page (viewed on Aug. 12, 2007). Includes bibliographical references (p. 72-74).

This thesis includes a video and a production report . The video documents a Denton artist, John Thomas Campbell who was working on a project for the Texas State Fair during the filming period. This documentary follows Campbell through his production on sculptures, using a biographical style to explore his life and his art work. The accompanying paper reports on the production background, pre-production process, and includes discussion of the problems encountered from production through post production stages.

Clarification of the bracteole restraint on germination and the development of an improved seed pre-treatment were the objectives of this study. Bracteole cell walls were isolated and hydrolyzed with 72% sulfuric acid followed by dilution and further hydrolysis. Individual monosaccharide yields were monitored with gas chromaixtography and colorimetry. Lignin was determined as the acid insoluble residue . Cell wall composition on a dry weight basis was 17.0% lignin, 32 . 75% glucose, 28.77% xylose, 7.21% arabinose, 1.11% galactose and 0.35% mannose. Linear xylans and glucans represent a large portion of the cell wall . The quantity of lignified tissue is extraordinarily large, resulting in a rigid, impermeable seed case. Bracteole cell walls were delignified with acid chlorite. A comparison of enzyme catalyzed hydrolysis of the untreated cell walls with delignified cell walls followed. Three commercial enzyme preparations were incubated with the samples separately and in combination treatments: cellulase (EC 3 . 2. 1.4) from Trichoderma viride supplemented with B- D-glucosidase (EC 3.2.1.21); crude-hemicellulase from Aspergillus niger; polygalacturonase (EC 3.2.1.15) from Aspergillus niger. The production of reducing groups was monitored. Enzyme catalyzed hydr olysis of lignified cell walls was limited: cellulase followed by polygalacturonase degraded 14.1% of the lignified cell wall, all other treatments yielded less than 10% degradation. Dramatic improvements in the activity of all enzymes was noted after delignification. Cellulase activity increased to 35%, hemicellulase to 25%, and polygalacturonase to 36% hydrolysis of the sample. Intact seeds were subjected to delignification with acid chlorite at 35 degrees. Of these seeds, half were treated with cellulase, supplemented as before . The germination percentages of delignified and delignified/enzyme treated seeds were compared with other common germination pre-treatments. Four hundred seeds of each treatment were sown in soil and allowed to germinate with 20 degree days and 15 degree nights. The thirty minute delignification left the seed viable, but still lignified: only 3% germinated as compared with 28.0% for physically scarified seeds, 6% for acid treated seeds, 5.5% for surface sterilized seeds, and 4.0% for cold water leached seeds. Physical scarification proved to be the easiest method of pre-treatment.

Joseph Campbell's comparative studies in mythology revealed to him that culturally bred mythologies, despite their ethnic inflections, continually point to universal archetypes and a common human identity. Campbell's belief in the common human identity stems from his adherence to Carl Jung's mystical perspective on myth, where archetypes of the personal and collective unconscious help us understand humankind in the past, present and future. Myth, like art, Campbell believed, should be interpreted metaphorically, in terms of connotation instead of denotation. Failure to interpret myth poetically leads to religious, social, and political divisiveness. Examples of consequences of a literally interpreted mythology prevail in contemporary ethnic and global warring. This thesis examines the prominent themes in Campbell's alternative philosophy of mythology, and particularly the interpretation of some selected notions in Biblical mythology which, he suggests, have to be reviewed and re-interpreted metaphorically. With the collapse of cultural boundaries due to modernity, the world community needs a mythology for the whole planet. This thesis will discuss the serious implications for religious education of Campbell's hermeneutics of mythology.
