No. 617 Stuart Ruckman
No full textTranscript (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 textThe 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
Inelastic scattering dynamics of ammonia with small molecules
No full textCrossed molecular beam velocity map imaging (VMI) is employed to state-selectively
record the NH3 inelastic scattering products from collisions with a series of colliders;
atomic Ar, diatomic D2, and the polyatomics CH4, C2H6 and C(CH3)4.
The differential cross sections (DCSs) presented for NH3-Ar expand on the existing
literature. The angular distribution of the scattering is found to exhibit a dependence on
the angular momentum projection quantum number (k) of the NH3 product state in
addition to the known dependency on the total angular momentum quantum number (J).
It is found that for increasing k the total scattering into sideways and backwards angles
(θ ≥ 60°) decreases.
For the smallest molecular colliders D2 and CH4 co-excitation is observed. DCSs are
presented for each NH3 product state and evidence of separate D2 co-excitation channels
is obtained by a new extraction method for acquiring multiple DCSs from a single VMI
image. The promotion of D2 into the JD2 = 3 rotational level exhibits an unusual
propensity for excitation at larger impact parameters. It is proposed that this is due to
interactions at larger distances with attractive regions of the potential energy surface
(PES), at smaller impact parameters the steeper gradient of the PES inhibits coexcitation.
The DCSs of NH3 scattering with methane, ethane and neopentane exhibit a striking
similarity across all three systems and when comparing individual NH3 product states
from a single collider. The DCSs are all dominated by forwards scattering angles (θ ≤
60°) for all NH3 collisional excitations. The dominant mechanism suggested is a “tug-of-
war” type trajectory, however calculations are required for confirmation of this
interaction.EPSRC grant number EP/J002534
John Stuart Mill’s projected science of society: 1827-1848
No full textThe 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

Increasing complexity in molecular chemical dynamics
No full textCrossed molecular beam (CMB) methods are combined with velocity map imaging (VMI) in
order to study the scattering of gaseous polyatomics from colliders of increasing complexity.
In addition to this, molecular dynamics (MD) simulations are used to model the surfaces of a
range of atmospherically relevant fatty acids and mixtures of hydrocarbons.
The first known measurements of k-j-k′ correlations for an inelastic scattering system, are
reported. The scattering system of choice was NO(A, 2+) + Ne, with the NO(A) initially
rotationally excited to the N = 4, j = 3.5 state, making this also one of only a small number of
studies of initially rotationally excited NO(A). During excitation molecules are aligned using
linearly polarised light, allowing for the extraction of both differential cross sections (DCSs)
and 0
2
polarisation dependent DCSs (PDDCSs).
Results of scattering experiments involving NH3 and a series of atomic and molecular
colliders of increasing size are reanalysed using a fitting routine modified by the author.
Where Ar and D2 are used as co-colliders, the DCSs extracted are compared to those from
quantum scattering (QS) calculations. Good experiment-theory agreement is found for the
work involving Ar. For the NH3 + D2 work, however, a much higher degree of product D2
excitation is observed in the experiments than predicted based on theory. DCSs are also
extracted from data on the scattering of NH3 from a series of hydrocarbons, representing one
of the first systems involving polyatomic-polyatomic scattering.
MD simulations of the vacuum-liquid interfaces of members of the oleic acid family, and of
mixtures of squalane and squalene, are presented, with an emphasis placed on which groups
are preferentially present at the surface, as opposed to the bulk. An above-statistical
distribution of methyl groups is observed at the interface, with the implications of this for
atmospheric pollution cycles discussed
Reading Stuart Elden’s The Birth of Territory
No full textThe Birth of Territory is an outstanding scholarly achievement, a book ‘of remarkable depth and breadth’, as noted by Alec Murphy in his comment, a book that already promises to become a ‘classic’ in geography, together with very few others published in the past decades. But Elden's book is also a difficult one to position within mainstream human geography. Its genealogical engagement with multiple sources/texts in various historical and linguistic contexts is far reaching, and it has very few precedents in the discipline—since it is deliberately inspired by the Cambridge school of contextual history, and the German tradition of Begriffsgeschichte, conceptual history. The Birth of Territory is also methodologically challenging, as its account of territory is carved out of a clear selection of ‘presences and absences’ operated by the author that, like all work of this kind, is open to criticism in relation to the strategies of inclusion/exclusion (of texts, concepts, people) adopted. What follows is a brief account of an Author meets Critics panel on The Birth of Territory held at the AAG Conference held in Tampa in April 2014
DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
No full textThe majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire
Quasi-classical trajectory study of the dynamics of the Cl + CH4→ HCl + CH3 reaction
No full textWe present an on-the-fly classical trajectory study of the Cl + CH4 -> HCl + CH3 reaction using a specific reaction parameter (SRP) AM1 Hamiltonian that was previously optimized for the Cl + ethane reaction [S. J. Greaves et al., J. Phys Chem A, 2008, 112, 9387]. The SRP-AM1 Hamiltonian is shown to be a good model for the potential energy surface of the title reaction. Calculated differential cross sections, obtained from trajectories propagated with the SRP-AM1 Hamiltonian compare favourably with experimental results for this system. Analysis of the vibrational modes of the methyl radical shows different scattering distributions for ground and vibrationally excited products.</p
