    No. 617 Stuart Ruckman

    Transcript (12, 40 pages) of two interviews by Matt Driscoll with Stuart Ruckman on April 9, 2010, and July 7, 2011Ruckman (b. 1966) was born in Salt Lake City, Utah. Stuart shares how his family, particularly his father, played a significant role in introducing him to the outdoors. Some of his initial explorations included a hike to the top of Mount Olympus when he was five years old, backpacking trips in the Wasatch and Uinta Mountains, and a successful summit attempt on the Grand Teton when he was twelve. Stuart discovered technical rock climbing due to the influence of his older brother Bret, five years Stuart\u27s senior. Bret learned under Dennis Turville, a well-respected Salt Lake climbing instructor. Stuart shares his observations on the Salt Lake climbing community of the late 1970s and 1980s, noting the intimacy of the community, while also pointing out the significant influence of a handful of climbers, including Merrill Bitter, Les Ellison, and Brian Smoot. He briefly describes the proliferation of new-route development in the Wasatch during his first decade in climbing. In collaboration with his brother Bret, Stuart published comprehensive guidebooks on climbing in the Wasatch Mountains. Stuart\u27s contributions as a first-ascensionist and co-author of Rock Climbing the Wasatch Range attest to his lasting impact on Utah climbing. Interview is part of the Outdoor Recreation History Project. Interviewer: Matt Driscol

    Redemption in the work of Francis Stuart

    No full text
    The idea of redemption is central to an understanding of the work of Francis Stuart. Through an examination of its development and expression, it is possible to demonstrate the integrity of his work and its distinctive qualities. Such a demonstration is necessary because Stuart's writing has been subjected to comparatively little scholarly inquiry, although reviews of his work, especially that produced since 1949, suggest that it is impressive and important. First, a general background to Stuart's work, a discussion of the special problems associated with reading it, and a summary of his corpus is provided. This indicates that the idea of redemption is important to his earliest writing. The state of redemption is shown to be a necessary apotheosis for Stuart's outcast heroes; it involves spiritual suffering through which may be found a sense of reintegration and a higher reality. This is expressed through interrelated themes such as those of gambler, artist and ordinary man; mystic and criminal; sacred and profane love; and spirituality and the mundane. The nature of the redemptive experience is further elaborated by distinctive, complex motifs, especially the hare, the ark and the woman-Christ. Their recurrence provides an important element in the unity of Stuart's work. Because Stuart's idea of the outcast raises important biographical questions, an examination of the relationship between Stuart's life and his work is made. Finally, the way in which the idea of redemption exists in the language structures of Stuart's novels is examined, with especial reference to his most recent work, The High Consistory. The thesis shows that the development of the these of redemption demonstrates the integrity of Stuart's work

    John Stuart Mill’s projected science of society: 1827-1848

    No full text
    The purpose of the thesis is to examine John Stuart Mill’s political thought from about 1827 to 1848 as an exercise in intellectual history. It focuses, first, on Mill’s view, formulated by the late 1830s, that contemporary society was ‘civilized’, and second, on his project of a science of society, which he aspired to develop in the late 1830s and early 1840s. By the late 1830s, Mill came to the view that his contemporary society was a ‘commercial society or civilization’, dominated by the middle, commercial class. The first part of my thesis, constituted by Chapters 2-4, discusses the way in which Mill formed his notion of civilization, and what he meant by the term ‘civilization’. Mill paid attention to the implications of the rise of the middle class, and regarded such phenomena of contemporary society as the corruption of the commercial spirit and excessive social conformity as an inevitable consequence of the rise of the middle class. The second part of the thesis, constituted by Chapters 5-9, examines Mill’s projected science of society. In the late 1830s and early 1840s, Mill attempted to develop a new science of society whose subject-matter was the nature and prospects of commercial, civilized society. This aspiration culminated in A System of Logic, published in 1843. In examining Mill’s projected science, I pay particular attention to the fact that he conceived new sciences of history and of the formation of character, both of which were indispensable in his project, although he failed to give a complete account of these sciences. My thesis shows that the implications of his interest both in history and in the formation of character are more significant than Mill scholars have assumed

    Similar estimates of population genetic composition and sex ratio derived from carcasses and faeces of Eurasian otter <i>Lutra lutra</i>

    Collecting faeces is viewed as a potentially efficient way to sample elusive animals. Nonetheless, any biases in estimates of population composition associated with such sampling remain uncharacterized. The goal of this study was to compare estimates of genetic composition and sex ratio derived from Eurasian otter Lutra lutra spraints (faeces) with estimates derived from carcasses. Twenty per cent of 426 wild‐collected spraints from SW England yielded composite genotypes for 7–9 microsatellites and the SRY gene. The expected number of incorrect spraint genotypes was negligible, given the proportions of allele dropout and false allele detection estimated using paired blood and spraint samples of three captive otters. Fifty‐two different spraint genotypes were detected and compared with genotypes of 70 otter carcasses from the same area. Carcass and spraint genotypes did not differ significantly in mean number of alleles, mean unbiased heterozygosity or sex ratio, although statistical power to detect all but large differences in sex ratio was low. The genetic compositions of carcass and spraint genotypes were very similar according to confidence intervals of θ and two methods for assigning composite genotypes to groups. A distinct group of approximately 11 carcass and spraint genotypes was detected using the latter methods. The results suggest that spraints can yield unbiased estimates of population genetic composition and sex ratio
