Are schools panoptic?
Schools are often understood by social researchers as panoptic spaces, where power is exercised through constant surveillance and monitoring. In this paper, I use Foucaultâs notorious account of the Panopticon as a point of departure for a detailed empirical investigation of the specificities of surveillance in schools. Drawing on ethnographic data from fieldwork in a primary school, I argue that how surveillance actually operated in this context diverged from the panoptic programme in two crucial ways: surveillance was (i) discontinuous rather than total, and therefore open to resistance and evasion, and (ii) exercised through sound and hearing as much as through vision
Five-country Study on Service and Volunteering in Southern Africa Malawi Country Report
This study on the nature and form of civic service and volunteering in Malawi followed a qualitative, descriptive research approach, drawing on information from an extensive document search, interviews with key informants responsible for supporting and/or implementing service and volunteering programmes and a focus group discussion with representatives of national and international organisations running structured service programmes, as well as those involved in district and community-based activities
Intermolecular C-H...N and C-H...O interactions in (2S,4S,5R)-(-)-3,4-dimethyl-5-phenyl-2-(1,3-thiazol-2-yl)-1,3-oxazolidine
The title compound, CââHââNâOS, prepared from
(1R,2S)-(-)-ephedrine, contains the oxazolidine ring
in an envelope conformation, with the nitrogen atom
0.623 (2) Ă
from the plane of the other four oxazolidine ring
atoms. Intermolecular C--H...N and C--H...O interactions
generate a two-dimensional hydrogen-bonded
network, with shortest C...N and C...O distances of
3.403 (3) and 3.463 (2) Ă
, respectively
Accreditation of practice educators: An expectation too far ?
The successful completion of practice placements is essential to the education
of occupational therapists; however, ensuring quality placements is challenging
for occupational therapy educators. In 2000, Brunel University introduced a
revised system of accreditation of practice educators which involved attendance
at a course, the supervision of a student and the submission of an essay to be
assessed.
An audit revealed that a total of 314 therapists attended 15 courses between
2000 and 2003; of these, 243 (77%) subsequently supervised students and
32 (10%) became accredited. The requirement to accredit practice educators,
which is a commendable attempt to ensure quality, may paradoxically have
been detrimental in achieving quality. The College of Occupational Therapistsâ
apparent change of emphasis on this topic is welcome
Stop-list slicing.
Traditional program slicing requires two parameters: a program location and a variable, or perhaps a set of variables, of interest. Stop-list slicing adds a third parameter to the slicing criterion: those variables that are not of interest. This third parameter is called the stoplist. When a variable in the stop-list is encountered, the data-flow dependence analysis of slicing is terminated for that variable. Stop-list slicing further focuses on the computation of interest, while ignoring computations known or determined to be uninteresting. This has the potential to reduce slice size when compared to traditional forms of slicing. In order to assess the size of the reduction obtained via stop-list slicing, the paper reports the results of three empirical evaluations: a large scale empirical study into the maximum slice size reduction that can be achieved when all program variables are on the stop-list; a study on a real program, to determine the reductions that could be obtained in a typical application; and qualitative case-based studies to illustrate stop-list slicing in the small. The large-scale study concerned a suite of 42 programs of approximately 800KLoc in total. Over 600K slices were computed. Using the maximal stoplist reduced the size of the computed slices by about one third on average. The typical program showed a slice size reduction of about one-quarter. The casebased studies indicate that the comprehension effects are worth further consideration
Conceptual techniques for reducing parasitic current gain of lateral pnp transistors
Two techniques have been conceptually proposed as possible means of reducing parasitic beta in lateral p-n-p transistors. One method uses a degenerate substrate and high concentration P /plus/ guard-ring diffusion, another places the base contact at the center of an annular ring structure
Diffusion technique stabilizes resistor values
Reduction of the contact resistance stabilizes the values, over a broad temperature range, of resistors used in linear integrated circuits. This reduction is accomplished by p-plus diffusion under the alloyed aluminum contacts
