"Rest Cure"
"Rest Cure" He sat in the sun with a blanket about him, considering, with his hands lying out like emaciated strangers before him, that today the sun would endure a little longer. Certainly it would survive until the trees below the terrace effaced it, toward four o’clock, like opened parasols. A crime it had been, the invalid thought, turning his head this way and that, to have ever built up one house before another in such a way that one man’s habitation cast a shadow upon another’s. The wh..
Search for the hero: an investigation into the sports heroes of British sports fans
This is an initial study into British sports fans’ heroes. A questionnaire was sent to 95 students (average age ¼ 19.75) to identify their sporting hero, the hero’s sport and nationality and the reasons for this choice. Football was the most common source of sports heroes, identified by 49% of participants with a sporting hero. The majority (60%, N ¼ 48) of heroes chosen by participants were British, with David Beckham the most popular choice. Differences were observed between the gender of participants, gender of hero chosen and the reasons for choosing the hero. The most common reason for selecting a hero was a personal trait rather than skill, while in the questionnaire a category of Local Affiliation was added to those suggested by previous work. It was concluded that to become a hero athletes should combine skill with devotion to family, charity work and a place in popular culture
Dust accretion and destruction in galaxy groups and clusters
We examine the dust distribution around a sample of 70,000 low redshift
galaxy groups and clusters derived from the Sloan Digital Sky Survey. By
correlating spectroscopically identified background quasars with the galaxy
groups we obtain the relative colour excess due to dust reddening. We present a
significant detection of dust out to a clustercentric distance of 30 Mpc/h in
all four independent SDSS colours, consistent with the expectations of weak
lensing masses of similar mass halos and excess galaxy counts. The wavelength
dependence of this colour excess is consistent with the expectations of a Milky
Way dust law with R_V=3.1. Further, we find that the halo mass dependence of
the dust content is much smaller than would be expected by a simple scaling,
implying that the dust-to-gas ratio of the most massive clusters (~10E14
Msun/h) is ~3% of the local ISM value, while in small groups (~10E12.7 Msun/h)
it is ~55% of the local ISM value. We also find that the dust must have a
covering fraction on the order of 10% to explain the observed color
differences, which means the dust is not just confined to the most massive
galaxies. Comparing the dust profile with the excess galaxy profile, we find
that the implied dust-to-galaxy ratio falls significantly towards the group or
cluster center. This has a significant halo mass dependence, such that the more
massive groups and clusters show a stronger reduction. This suggests that
either dust is destroyed by thermal sputtering of the dust grains by the hot,
dense gas or the intrinsic dust production is reduced in these galaxies.Comment: 10 pages, MNRAS, in pres
A National Action Plan for Promoting Preconception Health and Health Care in the United States (2012–2014)
Preconception health and health care (PCHHC) has gained increasing popularity as a key prevention strategy for improving outcomes for women and infants, both domestically and internationally. The Action Plan for the National Initiative on Preconception Health and Health Care: A Report of the PCHHC Steering Committee (2012–2014) provides a model that states, communities, public, and private organizations can use to help guide strategic planning for promoting preconception care projects. Since 2005, a national public–private PCHHC initiative has worked to create and implement recommendations on this topic. Leadership and funding from the Centers for Disease Control and Prevention combined with the commitment of maternal and child health leaders across the country brought together key partners from the public and private sector to provide expertise and technical assistance to develop an updated national action plan for the PCHHC Initiative. Key activities for this process included the identification of goals, objectives, strategies, actions, and anticipated timelines for the five work-groups that were established as part of the original PCHHC Initiative. These are further described in the action plan. To assist other groups doing similar work, this article discusses the approach members of the PCHHC Initiative took to convene local, state, and national leaders to enhance the implementation of preconception care nationally through accomplishments, lessons learned, and projections for future directions

What does a cue do? Comparing phonological and semantic cues for picture naming in aphasia
Purpose: Impaired naming is one of the most common symptoms in aphasia, often treated with cued picture naming paradigms. It has been argued that semantic cues facilitate the reliable categorisation of the picture, and phonological cues facilitate the retrieval of target phonology. To test these hypotheses, we compared the effectiveness of phonological and semantic cues in picture naming for a group of individuals with aphasia. To establish the locus of effective cueing, we also tested whether cue type interacted with lexical and image properties of the targets.
Method: Individuals with aphasia (n=10) were tested with a within-subject design. They named a large set of items (n=175) four times. Each presentation of the items was accompanied by a different cueing condition (phonological, semantic, non-associated word and tone). Item level variables for the targets (i.e., phoneme length, frequency, imageability, name agreement and visual complexity) were used to test the interaction of cue type and item variables. Naming accuracy data was analysed using generalised linear mixed effects models.
Results: Phonological cues were more effective than semantic cues, improving accuracy across individuals. However, phonological cues did not interact with phonological or lexical aspects of the picture names (e.g., phoneme length, frequency). Instead, they interacted with properties of the picture itself (i.e., visual complexity), such that phonological cues improved naming accuracy for items with low visual complexity.
Conclusions: The findings challenge the theoretical assumptions that phonological cues map to phonological processes. Instead, phonological information benefits the earliest stages of picture recognition, aiding the initial categorization of the target. The data help to explain why patterns of cueing are not consistent in aphasia, i.e., it is not the case that phonological impairments always benefit from phonological cues and semantic impairments form semantic cues. A substantial amount of the literature in naming therapy focuses on picture naming paradigms. Therefore, the results are also critically important for rehabilitation, allowing for therapy development to be more rooted in the true mechanisms through which cues are processed
The XMM Cluster Survey: X-ray analysis methodology
The XMM Cluster Survey (XCS) is a serendipitous search for galaxy clusters
using all publicly available data in the XMM-Newton Science Archive. Its main
aims are to measure cosmological parameters and trace the evolution of X-ray
scaling relations. In this paper we describe the data processing methodology
applied to the 5,776 XMM observations used to construct the current XCS source
catalogue. A total of 3,675 > 4-sigma cluster candidates with > 50
background-subtracted X-ray counts are extracted from a total non-overlapping
area suitable for cluster searching of 410 deg^2. Of these, 993 candidates are
detected with > 300 background-subtracted X-ray photon counts, and we
demonstrate that robust temperature measurements can be obtained down to this
count limit. We describe in detail the automated pipelines used to perform the
spectral and surface brightness fitting for these candidates, as well as to
estimate redshifts from the X-ray data alone. A total of 587 (122) X-ray
temperatures to a typical accuracy of < 40 (< 10) per cent have been measured
to date. We also present the methodology adopted for determining the selection
function of the survey, and show that the extended source detection algorithm
is robust to a range of cluster morphologies by inserting mock clusters derived
from hydrodynamical simulations into real XMM images. These tests show that the
simple isothermal beta-profiles is sufficient to capture the essential details
of the cluster population detected in the archival XMM observations. The
redshift follow-up of the XCS cluster sample is presented in a companion paper,
together with a first data release of 503 optically-confirmed clusters.Comment: MNRAS accepted, 45 pages, 38 figures. Our companion paper describing
our optical analysis methodology and presenting a first set of confirmed
clusters has now been submitted to MNRA
ECCO Essential Requirements for Quality Cancer Care : Prostate cancer
Background ECCO Essential Requirements for Quality Cancer Care (ERQCC) are written by experts representing all disciplines involved in cancer care in Europe. They give oncology teams, patients, policymakers and managers an overview of essential care throughout the patient journey. Prostate cancer Prostate cancer is the second most common male cancer and has a wide variation in outcomes in Europe. It has complex diagnosis and treatment challenges, and is a major healthcare burden. Care must only be a carried out in prostate/urology cancer units or centres that have a core multidisciplinary team (MDT) and an extended team of health professionals. Such units are far from universal in European countries. To meet European aspirations for comprehensive cancer control, healthcare organisations must consider the requirements in this paper, paying particular attention to multidisciplinarity and patient-centred pathways from diagnosis, to treatment, to survivorship.Peer reviewe
