A Narrative Exploration of 'Unhealthy' Attitudes Towards 'Healthy' Eating.
This qualitative research study employed a narrative method, in order to explore how individuals who consider themselves to have an âunhealthyâ approach to âhealthyâ eating make sense of this experience through the stories they tell. Narrative interviews were undertaken with four research participants and the data was subsequently subjected to a six stage Critical Narrative Analysis.
This allowed for a multi-layered analytical approach that identified narrative tone and function, the creation of identity through narrative, dominant narrative themes and the opportunity to interrogate the texts further from a feminist standpoint. In particular, attention was paid to the impact of broader sociocultural influences on the narratives. Implications for therapeutic practice with eating disordered individuals are subsequently explored and suggestions are made for the
direction of future research

Graduate recruitment at professional entry level: clinical judgements and empirically derived methods of selection
This research provides evidence to support the argument that selection procedures dependent upon clinical judgements, being used in the chartered accountancy profession, may well provide results not significantly different from those obtained by chance. Research has suggested that personality type, choice of vocation and performance are predictable from personal histories (Holland, 1976; Owens and Schoenfeldt, 1979; Eberhardt and Muchinsky, 1982a; Super, 1980; Wernimont and Campbell, 1968) and using a predictive model approach to scoring biographical data (biodata) is explored here as a means of improving the selection function. Part I of this study develops predictive models for scoring the biodata of applicants to the profession. An original contribution is made by carefully comparing two empirical model-building methodologies: the generally accepted, non-parametric, Weighted Application Blank technique and the parametric, logistic regression technique. The validity of both are explicitly tested using information from a sample of 23 training offices from 22 medium size chartered accountancy firms. The sample trainees were all non-accounting graduates entrants entering between 1985 and 1987 (N=665). Evidence is provided of the superiority of the results of the parametric models, in terms of true predictive validity. Relevant theory and the important implications of the results for related biodata studies generally are discussed. The result of applying the models to applicants, rather than recruits, is examined in a pilot study. An original approach to scoring applications is presented. Specifically developed software is provided to minimise both processing time and error margins. The biodata logit scores of the applicants and their likely success as trainees as indicated by that score, are compared with the firm's decision whether to accept or reject. Severe problems inherent in the judgemental approach to selection are revealed and the superior performance of the model-based approach demonstrated. Part II addresses the crucial issue of long term validation of biodata models by scoring a sample of recruits from 3 representative firms' 1988-90 entrants (N=323). The evidence does not support criticism of long term validity, as the logit models demonstrate effective performance, measured interms of the probability of correct classification, successfully predicting the criteria on those entering the profession up to 5 years after subjects used in model development. It is suggested that poor methodology may be responsible for excessive loss of validity over time in other studies and their lack of use of hard data. In addition, original evidence is provided to support the hypothesis of the generalizability of such models (i) across organizations and (ii) across samples significantly different from the development sample. This evidence suggests that, not only may the models be used to score applicants accounting firms of different sizes (and are therefore not organization-specific) but they may be used to score accounting graduates, who differ considerably from the original development sample (indicating that they, are not sample specific). The appropriateness of using these models in a manner similar to psychometric tests is considered. An assessment of approximate net profit associated with successful, failing or partially successful trainees is made. Accounting graduate trainees are more financially viable than non-accounting graduate

The association between body mass index and mood state
The weight of an individual appears to have an influence on mood state. Therefore, the purpose of this study was to evaluate this potential relationship. It was found that body mass index (BMI) does not have an association with the emotions of this sample (N = 206).This paper was initially delivered at the Annual Congress of the Biological Sciences Division of the South African Academy for Science and Art, ARC-Plant Protection Research Institute, Roodeplaat, Pretoria, South

Green Currents for Meromorphic Maps of Compact K\"ahler Manifolds
We consider the dynamics of meromorphic maps of compact K\"ahler manifolds.
In this work, our goal is to locate the non-nef locus of invariant classes and
provide necessary and sufficient conditions for existence of Green currents in
codimension one.Comment: Statement of Theorem 1.5 is slightly improved. Proposition 5.2 and
Theorem 5.3 are adde
Radiative Seesaw Mechanism at Weak Scale
We investigate an alternative seesaw mechanism for neutrino mass generation.
Neutrino mass is generated at loop level but the basic concept of usual seesaw
mechanism is kept. One simple model is constructed to show how this mechanism
is realized. The applications of this seesaw mechanism at weak scale to
cosmology and neutrino physics are discussed.Comment: 12 Pages, latex, no figure
Notes on Exact Multi-Soliton Solutions of Noncommutative Integrable Hierarchies
We study exact multi-soliton solutions of integrable hierarchies on
noncommutative space-times which are represented in terms of quasi-determinants
of Wronski matrices by Etingof, Gelfand and Retakh. We analyze the asymptotic
behavior of the multi-soliton solutions and found that the asymptotic
configurations in soliton scattering process can be all the same as commutative
ones, that is, the configuration of N-soliton solution has N isolated localized
energy densities and the each solitary wave-packet preserves its shape and
velocity in the scattering process. The phase shifts are also the same as
commutative ones. Furthermore noncommutative toroidal Gelfand-Dickey hierarchy
is introduced and the exact multi-soliton solutions are given.Comment: 18 pages, v3: references added, version to appear in JHE
Recent Progress at SLAC Extracting High Charge from Highly-Polarized Photocathodes for Future-Collider Applications
Future colliders such as NLC and JLC will require a highly-polarized
macropulse with charge that is more than an order of magnitude beyond that
which could be produced for the SLC. The maximum charge from the SLC
uniformly-doped GaAs photocathode was limited by the surface charge limit
(SCL). The SCL effect can be overcome by using an extremely high (>1019 cm-3)
surface dopant concentration. When combined with a medium dopant concentration
in the majority of the active layer (to avoid depolarization), the surface
concentration has been found to degrade during normal heat cleaning (1 hour at
600 C). The Be dopant as typically used in an MBE-grown superlattice cathode is
especially susceptible to this effect compared to Zn or C dopant. Some relief
can be found by lowering the cleaning temperature, but the long-term general
solution appears to be atomic hydrogen cleaning.Comment: 11 pages, 3 figures, 1 table, contributed to 10th Workshop on
Polarized Sources and Targets, Novosibirsk, Sept. 22-26, 2003, to be

Triggering an eruptive flare by emerging flux in a solar active-region complex
A flare and fast coronal mass ejection originated between solar active
regions NOAA 11514 and 11515 on July 1, 2012 in response to flux emergence in
front of the leading sunspot of the trailing region 11515. Analyzing the
evolution of the photospheric magnetic flux and the coronal structure, we find
that the flux emergence triggered the eruption by interaction with overlying
flux in a non-standard way. The new flux neither had the opposite orientation
nor a location near the polarity inversion line, which are favorable for strong
reconnection with the arcade flux under which it emerged. Moreover, its flux
content remained significantly smaller than that of the arcade (approximately
40 %). However, a loop system rooted in the trailing active region ran in part
under the arcade between the active regions, passing over the site of flux
emergence. The reconnection with the emerging flux, leading to a series of jet
emissions into the loop system, caused a strong but confined rise of the loop
system. This lifted the arcade between the two active regions, weakening its
downward tension force and thus destabilizing the considerably sheared flux
under the arcade. The complex event was also associated with supporting
precursor activity in an enhanced network near the active regions, acting on
the large-scale overlying flux, and with two simultaneous confined flares
within the active regions.Comment: Accepted for publication in Topical Issue of Solar Physics: Solar and
Stellar Flares. 25 pages, 12 figure
The Final Fate of the Rolling Tachyon
We propose an alternative interpretation of the boundary state for the
rolling tachyon, which may depict the time evolution of unstable D-branes in
string theory. Splitting the string variable in the temporal direction into the
classical part, which we may call "time" and the quantum one, we observe the
time dependent behaviour of the boundary. Using the fermion representation of
the rolling tachyon boundary state, we show that the boundary state correctly
describes the time-dependent decay process of the unstable D-brane into a
S-brane at the classical level.Comment: 9 pages, revte
