THE EFFECTS OF SHOE TYPE ON FOOT FUNCTIONING AND CONTACT PRESSURES DURING
The purpose of this study was to evaluate the functional effectiveness of a selection of women's walking shoes with particular attention being directed towards an assessment of specific shoe modifications which were included in a prototype model to theoretically reduce the undesirable characteristics associated with flexible shoes. Nine female subjects performed three trials for each of five shoe conditions. The prototype model decreased the encountered pressures and pressure integrals in the region of the second metatarsal-phalangeal joint. The use of the prototype shoe did not appear to unduly affect the gait of the subject
Augmenting forearm crutches with wireless sensors for lower limb rehabilitation
Forearm crutches are frequently used in the rehabilitation of an injury to the lower limb. The recovery rate is improved if the patient correctly applies a certain fraction of their body weight (specified by a clinician) through the axis of the crutch, referred to as partial weight bearing (PWB). Incorrect weight bearing has been shown to result in an extended recovery period or even cause further damage to the limb. There is currently no minimally invasive tool for long-term monitoring of a patient's PWB in a home environment. This paper describes the research and development of an instrumented forearm crutch that has been developed to wirelessly and autonomously monitor a patient's weight bearing over the full period of their recovery, including its potential use in a home environment. A pair of standard forearm crutches are augmented with low-cost off-the-shelf wireless sensor nodes and electronic components to provide indicative measurements of the applied weight, crutch tilt and hand position on the grip. Data are wirelessly transmitted between crutches and to a remote computer (where they are processed and visualized in LabVIEW), and the patient receives biofeedback by means of an audible signal when they put too much or too little weight through the crutch. The initial results obtained highlight the capability of the instrumented crutch to support physiotherapists and patients in monitoring usage
Improvement of the Staggered Fermion Operators
We present a complete and detailed derivation of the finite lattice spacing
corrections to staggered fermion matrix elements. Expanding upon arguments of
Sharpe, we explicitly implement the Symanzik improvement program demonstrating
the absence of order terms in the Symanzik improved action. We propose a
general program to improve fermion operators to remove corrections from
their matrix elements, and demonstrate this program for the examples of matrix
elements of fermion bilinears and . We find the former does have
corrections while the latter does not.Comment: 16 pages, latex, 1 figur
EXTRAVERSION-INTROVERSION AND THE SEXUAL BEHAVIOR OP COLLEGE STUDENTS APPROVED: Major Professor <^5
The results obtained indicated that there is little correlation between Extraversion-Introversion and most of the areas investigated for the population sampled. A correlation coefficient was performed on the five predictions using the male sample only, the female sample only, and the entire sample with males and females combined. Two of the fifteen coefficients proved to be significant and were discussed along with other findings of the study. Weaknesses of the study were also cited and suggestions were given regarding the improvement of similar studies which may be done in the future. EXTRAVERSION-INTROVERSION AND THE SEXUA
Lady Gaga as (dis)simulacrum of monstrosity
Lady Gaga’s celebrity DNA revolves around the notion of monstrosity, an extensively
researched concept in postmodern cultural studies. The analysis that is offered in this
paper is largely informed by Deleuze and Guattari’s notion of monstrosity, as well as
by their approach to the study of sign-systems that was deployed in A Thousand
Plateaus. By drawing on biographical and archival visual data, with a focus on the
relatively underexplored live show, an elucidation is afforded of what is really monstrous
about Lady Gaga. The main argument put forward is that monstrosity as sign
seeks to appropriate the horizon of unlimited semiosis as radical alterity and openness
to signifying possibilities. In this context it is held that Gaga effectively delimits her
unique semioscape; however, any claims to monstrosity are undercut by the inherent
limits of a representationalist approach in sufficiently engulfing this concept. Gaga is
monstrous for her community insofar as she demands of her fans to project their
semiosic horizon onto her as a simulacrum of infinite semiosis. However, this simulacrum
may only be evinced in a feigned manner as a (dis)simulacrum. The analysis of
imagery from seminal live shows during 2011–2012 shows that Gaga’s presumed
monstrosity is more akin to hyperdifferentiation as simultaneous employment of
heterogeneous and potentially dissonant inter pares cultural representations. The article
concludes with a problematisation of audience effects in the light of Gaga’s adoption of
a schematic and post-representationalist strategy in the event of her strategy’s emulation
