Pupils or prisoners? Institutional geographies and internal exclusion in UK secondary schools
This is the accepted version of the following article: Barker, J., Alldred, P., Watts, M. and Dodman, H. (2010), Pupils or prisoners? Institutional geographies and internal exclusion in UK secondary schools. Area, 42: 378â386, which has been published in final form at the link below. Copyright © 2010 The Authors.A growing interest in the geographies of schooling has led to an exploration of a variety of school spaces. An increasing number of secondary schools offer internal fixed-term exclusions so that temporary removal from school is not seen as âtime offâ for students. This particular strategy has led to the creation of a new type of space in schools. Drawing upon research undertaken in a London secondary school, this paper explores the geography of these new secluded spaces. We highlight that the configuration of physical space in Seclusion Units and the regulation of spatial practices create highly controlled and segregated spaces of punishment. We explore the powerful transformative effects of these spaces to change students' behaviour, social interaction and attitudes to learning. However, rather than simply creating docile subjects, we recognise that domination is never complete and we explore the extent and the limit of student resistance to the discipline and control of the Seclusion Unit
Testing collapse models with levitated nanoparticles: the detection challenge
We consider a nanoparticle levitated in a Paul trap in ultrahigh cryogenic
vacuum, and look for the conditions which allow for a stringent
noninterferometric test of spontaneous collapse models. In particular we
compare different possible techniques to detect the particle motion. Key
conditions which need to be achieved are extremely low residual pressure and
the ability to detect the particle at ultralow power. We compare three
different detection approaches based respectively on a optical cavity, optical
tweezer and a electrical readout, and for each one we assess advantages,
drawbacks and technical challenges
Subharmonics and Aperiodicity in Hysteresis Loops
We show that it is possible to have hysteretic behavior for magnets that does
not form simple closed loops in steady state, but must cycle multiple times
before returning to its initial state. We show this by studying the
zero-temperature dynamics of the 3d Edwards Anderson spin glass. The specific
multiple varies from system to system and is often quite large and increases
with system size. The last result suggests that the magnetization could be
aperiodic in the large system limit for some realizations of randomness. It
should be possible to observe this phenomena in low-temperature experiments.Comment: 4 pages, 3 figure
Studies in matter antimatter separation and in the origin of lunar magnetism
A progress report, covering lunar and planetary research is introduced. Data cover lunar ionospheric models, lunar and planetary geology, and lunar magnetism. Wind tunnel simulations of Mars aeolian problems and a comparative study of basaltic analogs of Lunar and Martial volcanic features was discussed
An Alternative Parameterization of R-matrix Theory
An alternative parameterization of R-matrix theory is presented which is
mathematically equivalent to the standard approach, but possesses features
which simplify the fitting of experimental data. In particular there are no
level shifts and no boundary-condition constants which allows the positions and
partial widths of an arbitrary number levels to be easily fixed in an analysis.
These alternative parameters can be converted to standard R-matrix parameters
by a straightforward matrix diagonalization procedure. In addition it is
possible to express the collision matrix directly in terms of the alternative
parameters.Comment: 8 pages; accepted for publication in Phys. Rev. C; expanded Sec. IV,

Starting a Streaming Video Program on a Limited Budget
Streaming videos are a desirable supplement to physical DVDs, but academic libraries may feel intimidated by the cost of adding another format to their collections. However, streaming videos can be surprisingly affordable. In the midst of a budget crunch, the librarians at Western Carolina University were able to start a streaming video program, first by selecting titles Ă la carte, and later by launching two streaming services, Kanopy (using a demand-driven acquisitions model) and Swank (using a mediated acquisitions model). These streaming videos allow for unlimited simultaneous access by local users as well as distance-education students, and they come with performance rights that help teaching faculty prevent copyright infringement. Despite some limitations with streaming videos, the format has been well received by faculty, students, and staff
Chromosomal Assignment of a Family of Human Oncogenes
A family of human transforming genes, previously shown to share homology with the ras family of viral oncogenes, maps to three different human chromosomes. A well-characterized mouse-human hybrid cell panel, combined with Southern blotting, was used in this study. The transforming gene of the T24 bladder carcinoma cell line maps to human chromosome 11. An oncogene isolated from the lung carcinoma cell line SK-Calu-1 maps to human chromosome 12. The third ras-related gene, cloned from SK-N-SH, a neuroblastoma cell line, maps to human chromosome 1
The Question of Low-Lying Intruder States in and Neighboring Nuclei
The presence of not yet detected intruder states in e.g. a
intruder at 9 excitation would affect the shape of the -delayed alpha spectra of and . In order to test the
plausibility of this assumption, shell model calculations with up to excitations in (and up to excitations in
) were performed. With the above restrictions on the model spaces, the
calculations did not yield any low-lying intruder state in . Another
approach -the simple deformed oscillator model with self-consistent frequencies
and volume conservation gives an intruder state in which is lower in
energy than the above shell model results, but its energy is still considerably
higher than 9 .Comment: 16 pages (RevTeX), 1 PS figure. To appear in Phys. Rev.
Metastability of a granular surface in a spinning bucket
The surface shape of a spinning bucket of granular material is studied using
a continuum model of surface flow developed by Bouchaud et al. and Mehta et al.
An experimentally observed central subcritical region is reproduced by the
model. The subcritical region occurs when a metastable surface becomes unstable
via a nonlinear instability mechanism. The nonlinear instability mechanism
destabilizes the surface in large systems while a linear instability mechanism
is relevant for smaller systems. The range of angles in which the granular
surface is metastable vanishes with increasing system size.Comment: 8 pages with postscript figures, RevTex, to appear in Phys. Rev.
