An Analysis Of Providers\u27 Practices Regarding Smoking Cessation
Clinical guidelines are the basis of any primary care setting. They were developed in order to give the healthcare provider access to information regarding screening, assistance, and management of certain ailments. Smoking cessation education is among the many clinical guidelines. Smoking is also among the modifiable risk factors for many diseases, including heart disease and cancer. A nonexperimental, ex post facto chart review was used to evaluate if healthcare professionals provided and documented smoking cessation education. A random sample o f (N=200) patients’ charts were selected at a clinic site in Northeast Mississippi. The purpose o f the study was to examine tobacco dependent patients’ charts to evaluate if healthcare providers implemented smoking cessation education and documented the health promoting behavior in accordance with the standards of care. The researchers discovered a large number of tobacco dependent patients’ charts that received little documentation o f smoking cessation education. Eight seven percent of the patients were assessed regarding smoking cessation; however, only 16% were advised to avoid smoke through the course o f their illness.

Identifying and prioritizing potential conservation sites in the Upper Oconee subbasin
Proceedings of the 2009 Georgia Water Resources Conference, April 27, 28, and 29, 2009
Athens, Georgia.Landscape scale conservation planning informed
by stakeholders is necessary for effective conservation
action. We developed a watershed level conservation
planning approach by working with two local land
trusts that operate in the Upper Oconee subbasin of northeast
Georgia. Emphasizing the interdependency of ecological
processes and human livelihood to area residents
motivates stewardship; hence, we focused on conservation
values that draw these linkages. In the United States, private
landowner conservation is essential for successful
protection of ecological processes and biodiversity. The
prevalent route for involving private landowners with
conservation is through partnerships with land trusts. A
rapid proliferation of land trusts across the U.S. over the
past decade indicates the increasing importance of private
land conservation efforts. As our primary objective, we
developed a GIS model for evaluating nine conservation
features in the watershed using a weighted scoring system
modified from the Georgia Land Conservation Program
evaluation criteria. We extracted the 70 highest-ranking
parcels as target recruitment parcels. The land trusts will
begin targeting these 70 parcels for easement recruitment
immediately. The second objective included quantifying
these nine conservation features for current easements and
other conservation lands to aid development of strategic
conservation plans. Land trust personnel agreed with the
relative scoring of their current holdings. We provided the
land trusts access to the entire database of values for the
features analyzed in all 34,024 parcels, empowering them
to visit a potential easement site with a priori knowledge;
thereby, enhancing the efficiency of their finite funding
and personnel resources.Sponsored by:

DARPA Phoenix Payload Orbital Delivery System: Progress towards Small Satellite Access to GEO
The emerging practice of hosting payloads on commercial geosynchronous Earth orbit (GEO) satellites is gaining traction throughout the space community because of the flight opportunities and budgetary savings that it offers. Using the hosted payload model, the DARPA Phoenix Payload Orbital Delivery (POD) system is meant to enable a higher tempo to GEO for small‐mass hardware items. The POD system proposes a departure from the typical hosted payload. The POD would provide a controlled release of the hosted payload from the commercial host near GEO. The POD standard user\u27s guide developed under the Phoenix program ensures compatibility with most of the approximately 15 commercial launches to GEO each year. By hosting with a standard user’s guide, commercial satellite providers would be capable of bringing hosted payloads quite late into the typical launch integration cycle. The combination of hightempo commercial launches and late integration would create an “express delivery” capability to GEO orbit. This POD capability would continue the paradigm shift of working with the commercial satellite provider directly to leverage the efficiencies of mass to orbit, reducing interactions with the launch provider. Phoenix is completing the design and ground testing of the POD system to help make access to new orbits more affordable and more routine for small‐mass systems
Bispectrum of the Sunyaev-Zel'dovich Effect
We perform a detailed study of the bispectrum of the Sunyaev-Zel'dovich
effect. Using an analytical model for the pressure profiles of the intracluster
medium, we demonstrate the SZ bispectrum to be a sensitive probe of the
amplitude of the matter power spectrum parameter sigma_8. We find that the
bispectrum amplitude scales as B_SZ ~ sigma_8^{11-12}, compared to that of the
power spectrum, which scales as A_tSZ ~ sigma_8^{7-9}. We show that the SZ
bispectrum is principally sourced by massive clusters at redshifts around
z~0.4, which have been well-studied observationally. This is in contrast to the
SZ power spectrum, which receives a significant contribution from less-well
understood low-mass and high-redshift groups and clusters. Therefore, the
amplitude of the bispectrum at l~3000 is less sensitive to astrophysical
uncertainties than the SZ power spectrum. We show that current high resolution
CMB experiments should be able to detect the SZ bispectrum amplitude with high
significance, in part due to the low contamination from extra-galactic
foregrounds. A combination of the SZ bispectrum and the power spectrum can
sharpen the measurements of thermal and kinetic SZ components and help
distinguish cosmological and astrophysical information from high-resolution CMB
maps.Comment: 12 pages, 8 figures, published in The Astrophysical Journa
Identification of genomic regions determining the phenological development leading to floral transition in wheat (Triticum aestivum L.)
Autumn-seeded winter cereals acquire tolerance to freezing temperatures and become vernalized by exposure to low temperature (LT). The level of accumulated LT tolerance depends on the cold acclimation rate and factors controlling timing of floral transition at the shoot apical meristem. In this study, genomic loci controlling the floral transition time were mapped in a winter wheat (T. aestivum L.) doubled haploid (DH) mapping population segregating for LT tolerance and rate of phenological development. The final leaf number (FLN), days to FLN, and days to anthesis were determined for 142 DH lines grown with and without vernalization in controlled environments. Analysis of trait data by composite interval mapping (CIM) identified 11 genomic regions that carried quantitative trait loci (QTLs) for the developmental traits studied. CIM analysis showed that the time for floral transition in both vernalized and non-vernalized plants was controlled by common QTL regions on chromosomes 1B, 2A, 2B, 6A and 7A. A QTL identified on chromosome 4A influenced floral transition time only in vernalized plants. Alleles of the LT-tolerant parent, Norstar, delayed floral transition at all QTLs except at the 2A locus. Some of the QTL alleles delaying floral transition also increased the length of vegetative growth and delayed flowering time. The genes underlying the QTLs identified in this study encode factors involved in regional adaptation of cold hardy winter wheat
Significant Surface-Water Connectivity of Geographically Isolated Wetlands
We evaluated the current literature, coupled with our collective research expertise, on surface-water connectivity of wetlands considered to be geographically isolated (sensu Tiner Wetlands 23:494–516, 2003a) to critically assess the scientific foundation of grouping wetlands based on the singular condition of being surrounded by uplands. The most recent research on wetlands considered to be geographically isolated shows the difficulties in grouping an ecological resource that does not reliably indicate lack of surface water connectivity in order to meet legal, regulatory, or scientific needs. Additionally, the practice of identifying geographically isolated wetlands based on distance from a stream can result in gross overestimates of the number of wetlands lacking ecologically important surface-water connections. Our findings do not support use of the overly simplistic label of geographically isolated wetlands . Wetlands surrounded by uplands vary in function and surface water connections based on wetland landscape setting, context, climate, and geographic region and should be evaluated as such. We found that the geographically isolated grouping does not reflect our understanding of the hydrologic variability of these wetlands and hence does not benefit conservation of the Nation’s diverse wetland resources. Therefore, we strongly discourage use of categorizations that provide overly simplistic views of surface water connectivity of wetlands fully embedded in upland landscapes
Impact of Cluster Physics on the Sunyaev-Zel'dovich Power Spectrum
We use an analytic model to investigate the theoretical uncertainty on the
thermal Sunyaev-Zel'dovich (SZ) power spectrum due to astrophysical
uncertainties in the thermal structure of the intracluster medium. Our model
accounts for star formation and energy feedback (from supernovae and active
galactic nuclei) as well as radially dependent non-thermal pressure support due
to random gas motions, the latter calibrated by recent hydrodynamical
simulations. We compare the model against X-ray observations of low redshift
clusters, finding excellent agreement with observed pressure profiles. Varying
the levels of feedback and non-thermal pressure support can significantly
change both the amplitude and shape of the thermal SZ power spectrum.
Increasing the feedback suppresses power at small angular scales, shifting the
peak of the power spectrum to lower ell. On the other hand, increasing the
non-thermal pressure support has the opposite effect, significantly reducing
power at large angular scales. In general, including non-thermal pressure at
the level measured in simulations has a large effect on the power spectrum,
reducing the amplitude by 50% at angular scales of a few arcminutes compared to
a model without a non-thermal component. Our results demonstrate that
measurements of the shape of the power spectrum can reveal useful information
on important physical processes in groups and clusters, especially at
high-redshift where there exists little observational data. Comparing with the
recent South Pole Telescope measurements of the small-scale cosmic microwave
background power spectrum, we find our model reduces the tension between the
values of sigma_8 measured from the SZ power spectrum and from cluster
abundances.Comment: 15 Pages, 9 Figures, updated to match version accepted by Ap
Geographically Isolated Wetlands: Rethinking a Misnomer
Abstract We explore the category Bgeographically isolated wetlands^(GIWs; i.e., wetlands completely surrounded by uplands at the local scale) as used in the wetland sciences. As currently used, the GIW category (1) hampers scientific efforts by obscuring important hydrological and ecological differences among multiple wetland functional types, (2) aggregates wetlands in a manner not reflective of regulatory and management information needs, (3) implies wetlands so described are in some way Bisolated,^an often incorrect implication, (4) is inconsistent with more broadly used and accepted concepts of Bgeographic isolation,^and (5) has injected unnecessary confusion into scientific investigations and discussions. Instead, we suggest other wetland classification systems offer more informative alternatives. For example, hydrogeomorphic (HGM) classes based on wellestablished scientific definitions account for wetland functional diversity thereby facilitating explorations into questions of connectivity without an a priori designation of Bisolation.^Additionally, an HGM-type approach could be used in combination with terms reflective of current regulatory or policymaking needs. For those rare cases in which the condition of being surrounded by uplands is the relevant distinguishing characteristic, use of terminology that does not unnecessarily imply isolation (e.g., Bupland embedded wetlands^) would help alleviate much confusion caused by the Bgeographically isolated wetlands^misnomer
