Gender and Health: The case for gender-sensitive health policy and health care delivery
There is growing national and international recognition that gender is an important indicator of health differences. The United Kingdom is in danger of falling behind many other countries that are beginning to recognise the crucial importance of gender to the development of effective health policy and practice. This briefing paper sets out some of the reasons why those involved in the gender and health partnership (GAHP) believe that it is time to place gender at the heart of the equalities agenda in health, and why it is important to ensure gender sensitivity in health policy, medical research and services. This briefing paper refers to the United Kingdom; however, Scotland is in the process of producing guidelines specifically on mainstreaming gender in health policy and service delivery
Local Stellar Kinematics from RAVE data - VII. Metallicity Gradients from Red Clump Stars
We investigate the Milky Way Galaxy's radial and vertical metallicity
gradients using a sample of 47,406 red clump stars from the RAVE DR4. This
sample is more than twice the size of the largest sample in the literature
investigating radial and vertical metallicity gradients. The absolute magnitude
of Groenewegen (2008) is used to determine distances to our sample stars. The
resulting distances agree with the RAVE DR4 distances Binney et al. (2014) of
the same stars. Our photometric method also provides distances to 6185 stars
that are not assigned a distance in RAVE DR4. The metallicity gradients are
calculated with their current orbital positions ( and ) and with
their orbital properties (mean Galactocentric distance, and ),
as a function of the distance to the Galactic plane:
d[Fe/H]/d- dex/kpc for kpc and
d[Fe/H]/d- dex/kpc for kpc. This
reaffirms the radial metallicity gradient in the thin disc but highlights that
gradients are sensitive to the selection effects caused by the difference
between and . The radial gradient is flat in the distance
interval 0.5-1 kpc from the plane and then becomes positive greater than 1 kpc
from the plane. The radial metallicity gradients are also eccentricity
dependent. We showed that d[Fe/H]/d-, -,
- and - dex/kpc for , ,
and sub-samples, respectively, in the distance
interval kpc. Similar trend is found for vertical
metallicity gradients. Both the radial and vertical metallicity gradients are
found to become shallower as the eccentricity of the sample increases. These
findings can be used to constrain different formation scenarios of the thick
and thin discs.Comment: 18 pages, including 16 figures and 6 tables, accepted for publication

Energy Pricing Policy and Environmental Quality in Nigeria: A Dynamic CGE Approach
The fuel subsidy policy as a policy had been argued to hamper efforts at environmental sustainability. Thus, this study investigates the extent to which the removal of fuel subsidy influences the level of carbon emissions in Nigeria over a 5 year period. It adopts the recursive dynamic version of the PEP Computable General Equilibrium (CGE) model based on the 2006 Nigerian Social Accounting Matrix (SAM). Simulating a partial, gradual and complete removal of import tariff on imported petrol indicates reduction of ..
Familial adenomatous polyposis coli: A case report
A 25-year-old man was admitted with a 6-month history of rectal bleeding, anal discharge and alteration in bowel habits. He gave a family history of a great grandmother who died of unknown causes but had a colostomy, and a grandmother who died of Carcinoma of the oesophagus. Both relatives were on maternal side. On examination he had a low rectal mass, which was obliterating the anal orifice. Colonoscopy was not possible but rectal biopsy revealed a well-differentiated carcinoma of the rectum. Abdomino- perineal resection was done. During surgery, he was found to have multiple polyps. Colonoscopy through the colostomy and biopsy confirmed the presence of multiple benign polyps involving the entire colon up to the caecum. After counselling, the patient had total colectomy and an ileostomy done. Subsequent screening of family members revealed a 28-yearold sister who had occasional painless rectal bleeding. The 28 year-old sister of the patient above had colonoscopy done and was found to have adenomatous polyps involving most of the colon up to the caecum. A near- total colectomy and ileorectal anastomosis was done and cautery of the rectal polyps. She is being followed up with 6-monthly proctoscopy and is doing well
The use of culturally themed HIV messages and their implications for future behaviour change communication campaigns: The case of Botswana
The ‘ABC' approach promoted at the beginning of the HIV/AIDS epidemic in Botswana has failed to yield significant behaviour change. Formative research was conducted in urban, semi-urban and rural areas to explore how the use of sociocultural messages depicted in posters elicited people's response to HIV/AIDS-related behaviours.The research interrogated values and practices underpinning Tswana philosophy in relation to parentchild communication, voluntary counselling and testing, condom use and faithfulness. A total of 206 individuals aged 15 - 49 years were purposively interviewed.The results showed that this campaign was perceived as an activation of positive Batswana culture to modify harmful norms, values and social practices, drawing upon those cultural aspects favouring more positive behaviour.We conclude that behaviour change communication should promote links to cultural values and principles.This can be achieved by: communication in other languages in order to reach all groups in Botswana; providing opportunities for venturing into other ways of communicating HIV/AIDS messages to Batswana in light of literacy skills; and using communication media that is developed on the basis of cultural approaches and focuses on segmented population groups.

A comprehensive study of the open cluster NGC 6866
We present CCD photometry of the field of the open cluster NGC 6866.
Structural parameters of the cluster are determined utilizing the stellar
density profile of the stars in the field. We calculate the probabilities of
the stars being a physical member of the cluster using their astrometric data
and perform further analyses using only the most probable members. The
reddening and metallicity of the cluster were determined by independent
methods. The LAMOST spectra and the ultraviolet excess of the F and G type
main-sequence stars in the cluster indicate that the metallicity of the cluster
is about the solar value. We estimated the reddening
mag using the vs two-colour diagram. The distance modula, the
distance and the age of NGC 6866 were derived as mag,
pc and Myr, respectively, by fitting
colour-magnitude diagrams of the cluster with the PARSEC isochrones. The
Galactic orbit of NGC 6866 indicates that the cluster is orbiting in a slightly
eccentric orbit with . The mass function slope was
derived by using the most probable members of the cluster.Comment: 14 pages, including 16 figures and 7 tables, accepted for publication
