âWe face rape. We face all thingsâ: Understandings of gender-based violence amongst female students at a South African university
This study explores how female residence students at a South African university understand and experience gender-based violence. This article examines how womenâs identities and social interactions are affected by the presence of gender-based violence in their communities, and specifically the issue of violence in higher education institutions. Social constructionist theory framed this study as it focuses on how these womenâs âtalkâ constructed their understanding of gender-based violence. Unstructured interviews were conducted with 12 female residence students and discourse analysis was used to analyse the interview material. Findings revealed that the fear of becoming a victim of gender-based violence serves to constrict the daily activities of these women. This research maps these ongoing discourses of fear which are present in all aspects of womenâs lives. It provides a formal articulation of womenâs experiences that are significant but frequently marginalised and normalised, showing the pervasive effects of fear of gender-based violence on identity and social life. The study contributes towards a growing body of knowledge surrounding the impact of gender-based violence at higher education institutions and works towards protecting students.Keywords: Gender-based violence; South Africa; women; students; higher education; fea
A Pinned Polymer Model of Posture Control
A phenomenological model of human posture control is posited. The dynamics
are modelled as an elastically pinned polymer under the influence of noise. The
model accurately reproduces the two-point correlation functions of experimental
posture data and makes predictions for the response function of the postural
control system. The physiological and clinical significance of the model is
discussed.Comment: uuencoded post script file, 17 pages with 3 figure
Diffusion-limited reaction for the one-dimensional trap system
We have previously discussed the one-dimensional multitrap system of finite
range and found the somewhat unexpected result that the larger is the number of
imperfect traps the higher is the transmission through them. We discuss in this
work the effect of a small number of such traps arrayed along either a constant
or a variable finite spatial section. It is shown that under specific
conditions, to be described in the following, the remarked high transmission
may be obtained for this case also. Thus, compared to the theoretical large
number of traps case these results may be experimentally applied to real
phenomenaComment: 18 pages, 8 PS Figures; 3 former figures were removed, a new section

Influence of auto-organization and fluctuation effects on the kinetics of a monomer-monomer catalytic scheme
We study analytically kinetics of an elementary bimolecular reaction scheme
of the Langmuir-Hinshelwood type taking place on a d-dimensional catalytic
substrate. We propose a general approach which takes into account explicitly
the influence of spatial correlations on the time evolution of particles mean
densities and allows for the analytical analysis. In terms of this approach we
recover some of known results concerning the time evolution of particles mean
densities and establish several new ones.Comment: Latex, 25 pages, one figure, submitted to J. Chem. Phy
Lattice theory of trapping reactions with mobile species
We present a stochastic lattice theory describing the kinetic behavior of
trapping reactions , in which both the and particles
perform an independent stochastic motion on a regular hypercubic lattice. Upon
an encounter of an particle with any of the particles, is
annihilated with a finite probability; finite reaction rate is taken into
account by introducing a set of two-state random variables - "gates", imposed
on each particle, such that an open (closed) gate corresponds to a reactive
(passive) state. We evaluate here a formal expression describing the time
evolution of the particle survival probability, which generalizes our
previous results. We prove that for quite a general class of random motion of
the species involved in the reaction process, for infinite or finite number of
traps, and for any time , the particle survival probability is always
larger in case when stays immobile, than in situations when it moves.Comment: 12 pages, appearing in PR

Proton structure function at small Q^2
A fit is made to the data for the proton structure function up to Q^2=10
GeV^2, including the real gamma p total cross-section. It is economical and
simple, and its form is motivated by physical principles. It is extrapolated
down to very small values of x. Data for the ratio (nu W_2^n/nu W_2^p) are also
fitted. A FORTRAN program for the fit to (nu W_2^p) is available by email on
request Figure 5 from the original version has been deleted.Comment: 10 pages plus 9 figure
Energy Relaxation in Nonlinear One-Dimensional Lattices
We study energy relaxation in thermalized one-dimensional nonlinear arrays of
the Fermi-Pasta-Ulam type. The ends of the thermalized systems are placed in
contact with a zero-temperature reservoir via damping forces. Harmonic arrays
relax by sequential phonon decay into the cold reservoir, the lower frequency
modes relaxing first. The relaxation pathway for purely anharmonic arrays
involves the degradation of higher-energy nonlinear modes into lower energy
ones. The lowest energy modes are absorbed by the cold reservoir, but a small
amount of energy is persistently left behind in the array in the form of almost
stationary low-frequency localized modes. Arrays with interactions that contain
both a harmonic and an anharmonic contribution exhibit behavior that involves
the interplay of phonon modes and breather modes. At long times relaxation is
extremely slow due to the spontaneous appearance and persistence of energetic
high-frequency stationary breathers. Breather behavior is further ascertained
by explicitly injecting a localized excitation into the thermalized array and
observing the relaxation behavior
