Dressing Their Best: Independent Fashion Bloggers and the Complexities of Ethos
Fashion is a site of cultural production where issues of gender, identity and consumerism meet. While the rhetoric of the fashion industry often remains focused on innovation at the expense of women\u27s lived experiences, independent fashion bloggers provide a necessary cultural critique of its practices. However, as the fashion industry pays more attention to bloggers in order to engage their growing readership, bloggers’ oppositional role has become more complicated. To explore the current context of these women’s writing in relation to a powerful economic industry, I analyze the role that ethos plays as a rhetorical concept and analyze how it is used by female bloggers who write about women’s fashion. In light of recent scholarship and of the current media landscape, bloggers’ use of ethos is important to their work even as it is complex and contradictory
Static critical behavior of the ferromagnetic transition in LaMnO3.14 manganite
The ferromagnetic phase transition in LaMnO3.14 is investigated by measuring
the dc magnetization as a function of magnetic field and temperature. Modified
Arrott plot and Kouvel Fisher analysis yield estimates for the critical
exponents beta, and gama, with values between that predicted for the Heisenberg
model and mean field theory. At low fields we found an anomalous small value of
beta, indicating that the critical behavior is influenced by the range of
magnetic fields used.Comment: Presented at ICM 2000 conference. Accepted for publication at J.

Half-skyrmion picture of single hole doped CuO_2 plane
Based on the Zhang-Rice singlet picture, it is argued that the half-skyrmion
is created by the doped hole in the single hole doped high-T_c cuprates with
N'eel ordering. The spin configuration around the Zhang-Rice singlet, which has
the form of superposition of the two different d-orbital hole spin states, is
studied within the non-linear \sigma model and the CP^1 model. The spin
configurations associated with each hole spin state are obtained, and we find
that the superposition of these spin configuration turns out to be the
half-skyrmion that is characterized by a half of the topological charge. The
excitation spectrum of the half-skyrmion is obtained by making use of Lorentz
invariance of the effective theory and is qualitatively in good agreement with
angle resolved photoemission spectroscopy on the parent compunds. Estimated
values of the parameters contained in the excitation spectrum are in good
agreement with experimentally obtained values. The half-skyrmion theory
suggests a picture for the difference between the hole doped compounds and the
electron doped compounds.Comment: 13 pages, 2 figures, to be published in Phys. Rev.
Timing Studies on RXTE Observations of SAX J2103.5+4545
SAX J2103.5+4545 has been continuously monitored for 900 days by
Rossi X-ray Timing Explorer (RXTE) since its outburst in July 2002. Using these
observations and previous archival RXTE observations of SAX J2103.5+4545, we
refined the binary orbital parameters and find the new orbital period as P=
(12.66536 0.00088) days and the eccentricity as 0.4055 0.0032. With
these new orbital parameters, we constructed the pulse frequency and pulse
frequency derivative histories of the pulsar and confirmed the correlation
between X-ray flux and pulse frequency derivative presented by Baykal, Stark
and Swank (2002). We constructed the power spectra for the fluctuations of
pulse frequency derivatives and found that the power law index of the noise
spectra is 2.13 0.6. The power law index is consistent with random walk
in pulse frequency derivative and is the steepest among the HMXRBs.
X-ray spectra analysis confirmed the inverse correlation trend between
power-law index and X-ray flux found by Baykal, Stark and Swank (2002).Comment: 23 pages, 7 figures, revised version accepted for publication in

The organization and operation of the Savannah River Plant`s groundwater monitoring program. Revision 3
The Savannah River Plant (SRP) is operated by Du Pont for the Department of Energy. The plant has been operating since 1952 and is one of the largest industrial facilities in the nation. Its function is to produce nuclear materials for the national defense. This paper describes the organization and operation of the Groundwater Monitoring Program (GMP) at the SRP. Groundwater has been actively monitored for radiological parameters at the SRP since the commencement of site operations in the 1950s. More recently, monitoring expanded to include chemical parameters and numerous additional facilities. The GMP is a large monitoring program. Over 700 wells monitor more than 70 facilities which are spread over 300 square miles. The program includes both Du Pont personnel and contractors and is responsible for all phases of groundwater monitoring: the installation (or abandonment) of monitoring wells, the determination of water quality (sample collection, analysis, data review, etc.), and the generation of reports
Pressure and linear heat capacity in the superconducting state of thoriated UBe13
Even well below Tc, the heavy-fermion superconductor (U,Th)Be13 has a large
linear term in its specific heat. We show that under uniaxial pressure, the
linear heat capacity increases in magnitude by more than a factor of two. The
change is reversible and suggests that the linear term is an intrinsic property
of the material. In addition, we find no evidence of hysteresis or of latent
heat in the low-temperature and low-pressure portion of the phase diagram,
showing that all transitions in this region are second order.Comment: 5 pages, 4 figure
Spin dynamics in a structurally ordered non-Fermi liquid compound: YbRh_2Si_2
Muon spin relaxation (muSR) experiments have been carried out at low
temperatures in the non-Fermi-liquid heavy-fermion compound YbRh_2Si_2. The
longitudinal-field muSR relaxation function is exponential, indicative that the
dynamic spin fluctuations are homogeneous. The relaxation rate 1/T_1 varies
with applied field as H^{-y}, y = 1.0 \pm 0.1, which implies a scaling law of
the form \chi''(\omega) \propto \omega^{-y} f(\omega/T), \lim_{x\to0} f(x) = x
for the dynamic spin susceptibility.Comment: 5 pages, 2 figures. To be published in proceedings of musr2002
