AccessMod 3.0: computing geographic coverage and accessibility to health care services using anisotropic movement of patients

Background Access to health care can be described along four dimensions: geographic accessibility, availability, financial accessibility and acceptability. Geographic accessibility measures how physically accessible resources are for the population, while availability reflects what resources are available and in what amount. Combining these two types of measure into a single index provides a measure of geographic (or spatial) coverage, which is an important measure for assessing the degree of accessibility of a health care network. Results This paper describes the latest version of AccessMod, an extension to the Geographical Information System ArcView 3.×, and provides an example of application of this tool. AccessMod 3 allows one to compute geographic coverage to health care using terrain information and population distribution. Four major types of analysis are available in AccessMod: (1) modeling the coverage of catchment areas linked to an existing health facility network based on travel time, to provide a measure of physical accessibility to health care; (2) modeling geographic coverage according to the availability of services; (3) projecting the coverage of a scaling-up of an existing network; (4) providing information for cost effectiveness analysis when little information about the existing network is available. In addition to integrating travelling time, population distribution and the population coverage capacity specific to each health facility in the network, AccessMod can incorporate the influence of landscape components (e.g. topography, river and road networks, vegetation) that impact travelling time to and from facilities. Topographical constraints can be taken into account through an anisotropic analysis that considers the direction of movement. We provide an example of the application of AccessMod in the southern part of Malawi that shows the influences of the landscape constraints and of the modes of transportation on geographic coverage. Conclusion By incorporating the demand (population) and the supply (capacities of heath care centers), AccessMod provides a unifying tool to efficiently assess the geographic coverage of a network of health care facilities. This tool should be of particular interest to developing countries that have a relatively good geographic information on population distribution, terrain, and health facility locations.

Novel autoantigens immunogenic in COPD patients

Background Chronic obstructive pulmonary disease (COPD) is a respiratory inflammatory condition with autoimmune features including IgG autoantibodies. In this study we analyze the complexity of the autoantibody response and reveal the nature of the antigens that are recognized by autoantibodies in COPD patients. Methods An array of 1827 gridded immunogenic peptide clones was established and screened with 17 sera of COPD patients and 60 healthy controls. Protein arrays were evaluated both by visual inspection and a recently developed computer aided image analysis technique. By this computer aided image analysis technique we computed the intensity values for each peptide clone and each serum and calculated the area under the receiver operator characteristics curve (AUC) for each clone and the separation COPD sera versus control sera. Results By visual evaluation we detected 381 peptide clones that reacted with autoantibodies of COPD patients including 17 clones that reacted with more than 60% of the COPD sera and seven clones that reacted with more than 90% of the COPD sera. The comparison of COPD sera and controls by the automated image analysis system identified 212 peptide clones with informative AUC values. By in silico sequence analysis we found an enrichment of sequence motives previously associated with immunogenicity. Conclusion The identification of a rather complex humoral immune response in COPD patients supports the idea of COPD as a disease with strong autoimmune features. The identification of novel immunogenic antigens is a first step towards a better understanding of the autoimmune component of COPD.

Phylogeny of Pasteurellaceae

This chapter provides an overview on the DNA based phylogeny of the family Pasteurellaceae and the genetic relatedness between taxa taking into account the various gene targets and approaches applied in the literature. The classical 16S rRNA gene based phylogeny as well as phylogenies based on house-keeping genes are described. Moreover, strength and weakness of the different trees and their topology are discussed based on the phylogenetic groups resolved. The data should help to get a clearer picture on the recent, current and future classification and also provide information to genetic characterization of members of the family. The history of phylogeny applied to the family as well as the phylogenetic history of the family is thereby presented. In this way it is the story of the search for the optimal phylogenetic marker without giving a final conclusive suggestion but it is also a resource for choosing the appropriate gene target(s) for people investigating the phylogeny of groups of Pasteurellaceae.

Library Assessment Trends Report, 2010–2011

The field of library assessment continues to grow. The annual Library Assessment Trends Report provides a brief synopsis of the more important trends in library assessment. It is hoped these brief reports will facilitate the Dean of the Library’s understanding of assessment trends. These reports provide information that supports data driven decisions. Additionally, the reports are an outreach method that supports a greater institutional understanding of library assessment. Library assessment supports strategic planning, improved processes, and a greater understanding of our users’ needs.

The Influence of MGA and PG600 on the Out of Season Reproductive Performance of Ewes

Seasonal lamb supply has been established as one of the major hindrances to the American sheep industry. The ability to consistently lamb ewes on an accelerated production system offers additional benefits of reduced maintenance costs, more uniform cash flow along with reduced labor and facility demands. Previous work at McNay with spring breeding indicated that light priming rams regardless of genetic base improved conception rates, however, MGA feeding postweaning gave inconsistent and sometimes depressed reproductive activity in ewes. This study was conducted to evaluate the use of MGA in late lactation and a single PG600 injection at weaning, either individually or in combination.

Use of Ultrasound Backfat Estimates to Form Marketing Groups Prior to Finishing for Feedlot Steers

An experiment was conducted using 95 Continental crossbred steers. The cattle were sorted by ultrasound 160 days before slaughter into a low backfat group (Low BF) and a higher backfat group (High BF). Half of the Low BF and half of the High BF were implanted whereas the other halves were not. Data from the experiment were used in two hypothetical markets. One market was a high yield beef program (HY) that did not allow the use of implants. The second market was a commodity beef program (CM) that allowed the use of implants. The cattle were priced as an unsorted group (ALL) and two sorted groups (Low BF and High BF) within the HY (non-implanted) and CM (implanted) markets. The CM program had a base price of $1.05/lb hot carcass weight (HCW) with a $0.15/lb HCW discount for quality grade (QG) Select and a $0.20/lb HCW discount for yield grade (YG) 4. The HY program used a base price of $1.07/lb HCW with premiums ($/lb HCW) paid for YG £ .9 (.15), 1.0 - 1.4 (.10), and 1.5 - 1.9 (.03). The carcasses were discounted ($/lb HCW) for YG 2.5 - 2.9 (.03), 3.0 - 3.9 (.15), and ³ 4.0 (.35). This data set provides good evidence that the end point at which to sell a group of cattle depends on the particular market. Sorting had an economic advantage over ALL in the HY Low BF and the CM High BF groups. The HY High BF cattle should have been sold sooner due to the discounts recieved for increased YG. The increased YG was directly affected by an increase in BF. Furthermore, the CM Low BF group should have been fed longer to increase the number of carcasses grading Choice.

ISU ADVANCE Annual Report, Year 2: June 2008

The goal of the ISU ADVANCE program is to investigate the effectiveness of a multilevel collaborative effort to produce institutional transformation that results in the full participation of women faculty in science, technology, engineering and math fields in the university. Our approach focuses on transforming departmental cultures (views, attitudes, norms and shared beliefs), practices (what people say and do), and structures (physical and social arrangements), as well as university policies, through active participation of individuals at all levels of the university.

Taking the Law into Your Own Hands: Establishing an In-house Book Repair Program

Law collections pose some unique problems in terms of their physical care due to filing and updating practices, use patterns and special binding structures such as loose-leafs and pocket parts. This workshop is designed to address specific preservation needs of law collections through lecture, demonstration and hands-on opportunities. Participants will learn the fundamentals of book repair, treatment options and decision-making, and preservation best practices. Emphasis will be placed on moving knowledge into practice through guidelines for establishing institution-appropriate in house book repair programs, by training the trainers in basic book repair techniques and providing all participants with a start-up tool kit.

The 1960s: A Bibliography

The time period covered by this bibliography is circa 1960 to 1974, an unusual "decade," to be sure. But because the Civil Rights movements and Watergate framed this era, it became impossible to compile a bibliography on the 1960s without entering the 1970s. The Vietnam War did not end until 1975, which would seem a logical place to end the decade. However, Nixon's resignation sparked more public interest and energy than did the anti-climax of the end of the war. Thus, the time period covered. Although there are some key books on the Civil Rights Movement, which started in the late 1950s, that movement has been adequately covered in other resources.
