The subversion of women's anger in travel guidebooks
Guidebooks have a privileged role in tourism as they direct bodily engagement with destinations, and yet few feminist leisure scholars have analysed guidebooks. This paper applies a feminist critical discourse analysis (FCDA) to explore Lonely Planet’s online travel advice for women. The results of the FCDA reveal that Lonely Planet advice acts to subvert women travellers’ anger, particularly when confronted with gender-based violence such as sexual harassment. The guidance offered to women travellers transmits the message that anger at gender-based violence is not legitimate and suggests that feeling anger when abroad is culturally inappropriate. This paper contributes to the literature by demonstrating that women’s anger is routinely subverted, particularly in contexts where freedom is ostensibly promised, such as leisure. The findings of this paper illustrate the value in applying FCDA to instances of otherwise hidden subversion and oppression and should inform future advice offered to women travellers

Discovery of a Binary Centaur
We have identified a binary companion to (42355) 2002 CR46 in our ongoing
deep survey using the Hubble Space Telescope's High Resolution Camera. It is
the first companion to be found around an object in a non-resonant orbit that
crosses the orbits of giant planets. Objects in orbits of this kind, the
Centaurs, have experienced repeated strong scattering with one or more giant
planets and therefore the survival of binaries in this transient population has
been in question. Monte Carlo simulations suggest, however, that binaries in
(42355) 2002 CR46 -like heliocentric orbits have a high probability of survival
for reasonable estimates of the binary's still-unknown system mass and
separation. Because Centaurs are thought to be precursors to short period
comets, the question of the existence of binary comets naturally arises; none
has yet been definitively identified. The discovery of one binary in a sample
of eight observed by HST suggests that binaries in this population may not be
uncommon.Comment: 20 pages, 4 figures, 1 table accepted for publication in Icaru
Evidence for the outcomes and impact of clinical pharmacy: context of UK hospital pharmacy practice
Objectives: The role of clinical pharmacists in hospitals has evolved and continues to expand. In the UK, outside of a few national policy drivers, there are no agreed priorities, measures or defined outcomes for hospital clinical pharmacy (CP). This paper aims to (1) highlight the need to identify and prioritise specific CP roles, responsibilities and practices that will bring the greatest benefit to patients and health systems and (2) describe systematic weaknesses in current research methodologies for evaluating CP services and propose a different approach.
Method: Published reviews of CP services are discussed using the Economic, Clinical and Humanistic Outcomes framework. Recurring themes regarding study methodologies, measurements and outcomes are used to highlight current weaknesses in studies evaluating CP.
Results: Published studies aiming to demonstrate the economic, clinical or humanistic outcomes of CP often suffer from poor research design and inconsistencies in interventions, measurements and outcomes. This has caused difficulties in drawing meaningful conclusions regarding CP’s definitive contribution to patient outcomes.
Conclusion: There is a need for more research work in National Health Service (NHS) hospitals, employing a different paradigm to address some of the weaknesses of existing research on CP practice. We propose a mixed-methods approach, including qualitative research designs, and with emphasis on cost-consequence analyses for economic evaluations. This approach will provide more meaningful data to inform policy and demonstrate the contribution of hospital CP activities to patient care and the NHS
Constructing smooth potentials of mean force, radial, distribution functions and probability densities from sampled data
In this paper a method of obtaining smooth analytical estimates of
probability densities, radial distribution functions and potentials of mean
force from sampled data in a statistically controlled fashion is presented. The
approach is general and can be applied to any density of a single random
variable. The method outlined here avoids the use of histograms, which require
the specification of a physical parameter (bin size) and tend to give noisy
results. The technique is an extension of the Berg-Harris method [B.A. Berg and
R.C. Harris, Comp. Phys. Comm. 179, 443 (2008)], which is typically inaccurate
for radial distribution functions and potentials of mean force due to a
non-uniform Jacobian factor. In addition, the standard method often requires a
large number of Fourier modes to represent radial distribution functions, which
tends to lead to oscillatory fits. It is shown that the issues of poor sampling
due to a Jacobian factor can be resolved using a biased resampling scheme,
while the requirement of a large number of Fourier modes is mitigated through
an automated piecewise construction approach. The method is demonstrated by
analyzing the radial distribution functions in an energy-discretized water
model. In addition, the fitting procedure is illustrated on three more
applications for which the original Berg-Harris method is not suitable, namely,
a random variable with a discontinuous probability density, a density with long
tails, and the distribution of the first arrival times of a diffusing particle
to a sphere, which has both long tails and short-time structure. In all cases,
the resampled, piecewise analytical fit outperforms the histogram and the
original Berg-Harris method.Comment: 14 pages, 15 figures. To appear in J. Chem. Phy
Infrared Emissions from Shock Heated Hydrocarbons
The primary objective of this study was to ascertain whether low molecular weight hydrocarbons (LMWH) in the range C4 to C7, upon heating to temperatures above 900 K, emit IR radiations at frequencies that correspond to the 'unidentified infrared' (UIR) features - the recorded emissions from a variety of astronomical sources - reflection nebulae, HII regions, planetary nebulae, spiral galaxies and other extra galactic objects. We describe IR emission spectra recorded from shock-heated gases (C2H2; (H3C)2C = CH2; H2C = C(CH3) - C(CH3) = CH2; (H3C)2C = CH - C(CH3) = CH2), that arise from excitation of the fundamental C-H stretching vibrations. While the IR emissions from LMWH, anticipated over the entire spectra range, do not present a perfect match to UIR, the correspondence over several wavelength regions is better than the emissions anticipated from polycyclic aromatic hydrocarbon (PAH) species. Finally, we briefly review the range of proposals that have been presented for the origin of the UIR bands

Linear dust polarization during the embedded phase of protostar formation
Measuring polarization from thermal dust emission can provide constraints on
the magnetic field structure around embedded protostars. However, interpreting
the observations is challenging without models that consistently account for
both the complexity of the protostellar birth environment and polarization
mechanisms. We aim to provide a better understanding with a focus on
bridge-like structures such as that observed towards the protostellar multiple
IRAS 16293--2422 by comparing synthetic polarization maps of thermal reemission
with observations. We analyze the magnetic field properties associated with the
formation of a protostellar multiple based on ideal MHD 3D zoom-in simulations
carried out with the RAMSES code. To compare with observations, we post-process
a snapshot of a bridge-like structure that is associated with a forming triple
star system with the radiative transfer code POLARIS and produce
multi-wavelength dust polarization maps. In the most prominent bridge of our
sample, the typical density is about 10^(-16) g cm^(-3), and the magnetic field
strength is about 1 to 2 mG. The magnetic field structure has an elongated
toroidal morphology and the dust polarization maps trace the complex
morphology. In contrast, the magnetic field strength associated with the
launching of asymmetric bipolar outflows is significantly more magnetized (~100
mG). At {\lambda}=1.3 mm, the orientation of grains in the bridge is similar
for the case accounting for radiative alignment torques (RATs) compared to
perfect alignment with magnetic field lines. However, the polarization fraction
in the bridge is three times smaller for the RAT scenario compared to assuming
perfect alignment. At shorter wavelengths ({\lambda} < 200 {\mu}m), dust
polarization does not trace the magnetic field because other effects such as
self-scattering and dichroic extinction dominate the orientation of the
polarization.Comment: 18 pages, 12 figures plus 3 figures in the appendix, accepted for
