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

A numerical canonical transformation approach to quantum many body problems
We present a new approach for numerical solutions of ab initio quantum
chemistry systems. The main idea of the approach, which we call canonical
diagonalization, is to diagonalize directly the second quantized Hamiltonian by
a sequence of numerical canonical transformations.Comment: 10 pages, 3 encapsulated figures. Parts of the paper are
substantially revised to refer to previous similar method
Legal socialization effects on democratization
As is the case with all our joint publications, this article represents a genuine research collaboration between the authors, with equal contributions. Therefore, neither is first or second author. This article uses data from a collaborative project that grew out of the Law and Society Associations Working Group on Orientations toward Law and Normative Ordering‘. Ellen S. Cohn, lames L. Gibson, Susan O. White, Joseph Sanders, Joan McCord, and Felice Levine were responsible for the development and implementation of the research design. Funding for the project was provided by the (US) National Science Foundation (SE 13237 and SIR 11403). Our European collaborators include Chantal Kourilsky-Augeven (France), Grazyna Skapska, Iwona Jakubowska-Branicka, and Maria Barucka-Arctowa (Poland), Andras Sajo (Hungary), Rosemary Barberet (Spain), and Stefka Naoumova (Bulgaria). Pam Moore, Kris Guffey, Marika Litras, Julie Nadeau, John Kraft, and Kimberly Smirles provided valuable research assistance
Observed variability in the Fraunhofer line spectrum of solar flux, 1975 - 1980
Over the five years double-pass spectrometer observations of the Sun-as-a-star revealed significant changes in line intensities. The photospheric component weakened linearly with time 0 to 2.3%. From a lack of correlation between these line weakenings and solar activity indicators like sunspots and plage, a global variation of surface properties is inferred. Model-atmosphere analysis suggests a slight reduction in the lower-photospheric temperature gradient corresponding to a 15% increase in the mixing length within the granulation layer. Chromospheric lines such as Ca II H and K, Ca II 8543 and the CN band head weaken synchronously with solar activity. Thus, the behavior of photospheric and chromospheric lines is markedly different, with the possibility of secular change for the former
Who Panics During Panics? Evidence from a Nineteenth Century Savings Bank
Using records of the bank accounts of individual depositors, this paper provides a detailed microeconomic analysis of two nineteenth century banking panics. The panics of 1854 and 1857 were not characterized by an immediate mass panic of depositors and had important time dimensions. We examine depositor behavior using a hazard model. Contagion was the key factor in 1854 but it was not strong enough to create more than a local panic. In contrast, the panic of 1857 began with runs by businessmen and banking sophisticates followed by less informed depositors. Uninformed contagion may have been present, but the evidence suggests that this panic was driven by informational shocks in the face of asymmetric information about the true condition of bank portfolios.

Evidence for symmetric chromosomal inversions around the replication origin in bacteria.
BackgroundWhole-genome comparisons can provide great insight into many aspects of biology. Until recently, however, comparisons were mainly possible only between distantly related species. Complete genome sequences are now becoming available from multiple sets of closely related strains or species.ResultsBy comparing the recently completed genome sequences of Vibrio cholerae, Streptococcus pneumoniae and Mycobacterium tuberculosis to those of closely related species - Escherichia coli, Streptococcus pyogenes and Mycobacterium leprae, respectively - we have identified an unusual and previously unobserved feature of bacterial genome structure. Scatterplots of the conserved sequences (both DNA and protein) between each pair of species produce a distinct X-shaped pattern, which we call an X-alignment. The key feature of these alignments is that they have symmetry around the replication origin and terminus; that is, the distance of a particular conserved feature (DNA or protein) from the replication origin (or terminus) is conserved between closely related pairs of species. Statistically significant X-alignments are also found within some genomes, indicating that there is symmetry about the replication origin for paralogous features as well.ConclusionsThe most likely mechanism of generation of X-alignments involves large chromosomal inversions that reverse the genomic sequence symmetrically around the origin of replication. The finding of these X-alignments between many pairs of species suggests that chromosomal inversions around the origin are a common feature of bacterial genome evolution
Identifying pathways of exposure to highway pollutants in great crested newt (Triturus cristatus) road mitigation tunnels: Exposure pathways of highway pollutants to Triturus cristatus
Road mitigation tunnels are increasingly deployed for amphibians but very little is known about chemical pollution in such schemes. We assessed pollution pressures associated with road runoff at a major great crested newt mitigation scheme in England. Sediments and waters in the mitigation system were analysed for major physico-chemical parameters, trace metals and total petroleum hydrocarbons and compared to a nearby reference site. Seven out of eight tested metals including copper, zinc, lead and iron were in significantly greater concentrations in the tunnels than at a reference site and at environmentally significant concentrations. Water samples also exhibited elevated concentrations of aluminium and chromium and occasionally extreme alkaline pH associated with leaching of portlandite in tunnel cements. High conductivity values in waters and sediments corresponding with seasonal de-icing salt application were also apparent. The study highlights the potential pollutant pressures for amphibians associated with large-scale urban development and road mitigation schemes
Observing the sky at extremely high energies with the Cherenkov Telescope Array: Status of the GCT project
The Cherenkov Telescope Array is the main global project of ground-based
gamma-ray astronomy for the coming decades. Performance will be significantly
improved relative to present instruments, allowing a new insight into the
high-energy Universe [1]. The nominal CTA southern array will include a
sub-array of seventy 4 m telescopes spread over a few square kilometers to
study the sky at extremely high energies, with the opening of a new window in
the multi-TeV energy range. The Gamma-ray Cherenkov Telescope (GCT) is one of
the proposed telescope designs for that sub-array. The GCT prototype recorded
its first Cherenkov light on sky in 2015. After an assessment phase in 2016,
new observations have been performed successfully in 2017. The GCT
collaboration plans to install its first telescopes and cameras on the CTA site
in Chile in 2018-2019 and to contribute a number of telescopes to the
subsequent CTA production phase.Comment: 8 pages, 7 figures, ICRC201
