Students' everyday problems: a systematic qualitative analysis
The growing acceptance ofqualitative research promises to minimise the perceived gap between counselling practitioner and counselling researcher, but brings with it the challenge offinding methods for dealing systematically, yet respectfully, with textual data. This article presents just such a method. Seventy-five students provided brief descriptions of the everyday problems of their university careers. A random sample of these first hand accounts was then sorted by 30 further students. Hierarchical cluster analysis and multidimensional scaling procedures were used to construct a categorical and dimensional framework within which the original first hand accounts are explored in more detail

The military career of John Churchill, Duke of Marlborough
The prpose of this thesis is two-fold: First, it is the author\u27s intention to present a short biography of John Churchill from his birth in 1650 to the outbreak of the great continental war of 1700. The second and primary purpose is to evaluate Marlborough \u27s military role during the War of Spanish Succession, while serving as Commander in Chief, Allied Armies, on the Continent. The four major battles to be emphasized in this section are Blenheim, 1704; Ramilles, 1706; Oudenarde, 1706; and Malpaquet, 1709, with primary emphasis on Blenheim. The central theme of this thesis is to illustrate how Marlborough \u27s mastery of the battlefield completely revolutionized both strategy and tactics of land warfare. During each of the four campaigns, his tactics, overall strategy, logistics, support, lines of communications, cavalry and artillery employment, and personal leadership will be evaluated
Vertical quantum wire realized with double cleaved-edge overgrowth
A quantum wire is fabricated on (001)-GaAs at the intersection of two
overgrown cleaves. The wire is contacted at each end to n+ GaAs layers via
two-dimensional (2D) leads. A sidegate controls the density of the wire
revealing conductance quantization. The step height is strongly reduced from
2e^2/h due to the 2D-lead series resistance. We characterize the 2D density and
mobility for both cleave facets with four-point measurements. The density on
the first facet is modulated by the substrate potential, depleting a 2um wide
strip that defines the wire length. Micro-photoluminescence shows an extra peak
consistent with 1D electron states at the corner.Comment: 4 pages, 4 figure

Investigating the Intelligibility of a Computer Vision System for Blind Users
Computer vision systems to help blind usersare becoming increasingly common yet often these systems are not intelligible. Our work investigates the intelligibility of a wearable computer vision system to help blind users locate and identify people in their vicinity. Providing a continuous stream of information, this system allows us to explore intelligibility through interaction and instructions, going beyond studies of intelligibility that focus on explaining a decision a computer vision system might make. In a study with 13 blind users, we explored whether varying instructions (either basic or enhanced) about how the system worked would change blind users’ experience of the system. We found offering a more detailed set of instructions did not affect how successful users were using the system nor their perceived workload. We did, however, find evidence of significant differences in what they knew about the system, and they employed different, and potentially more effective, use strategies. Our findings have important implications for researchers and designers of computer vision systemsfor blind users, as well more general implications for understanding what it means to make interactive computer vision systems intelligible
Edge Magnetoplasmons in Quantum Hall Line Junction Systems
A quantum Hall line junction system consists of a one-dimensional Luttinger
liquid (LL) and two chiral channels that allow density waves incident upon and
reflected by the LL to be measured separately. We demonstrate that interactions
in a quantum Hall line junction system can be probed by studying edge
magnetoplasmon absorption spectra and their polarization dependences. Strong
interactions in the junction lead to collective modes that are isolated in
either Luttinger liquid or contact subsystems.Comment: 4 pages, 3 figures, submitted to Phys. Rev. B Rapid Communicatio
