Book Description
This report presents the results of JTRP Project: "A Systematic Approach of Identifying Safety Intervention Programs for Indiana (SNIP2)," which aimed to develop SNIP2 to support identification of roads that have excessive crashes of the types defined by the user. In addition, this tool is capable of selecting the best combination of high-crash roads and relevant safety interventions that maximizes the safety benefits and keeps the total cost within the budget and other user-defined constraints.Unlike other studies considering the implementation time of safety projects, the optimization objective of SNIP2 is to identify an optimal combination of countermeasures renewable within a long time horizon. This simplification is accomplished by representing the projects through their annualized costs and benefits. It allows consideration of many projects for large road networks and it makes the SNIP2 suitable for identification of safety focus areas in strategic safety plans. The SNIP optimizer'an heuristic approximation of a large-size mixed integer knapsack problem based on a greedy search was extensively tested and evaluated. It was found producing optimal or near-optimal solutions in a sufficiently short time. Another research result is a comprehensive catalog of countermeasures for Indiana'a list of countermeasure names, road and crash conditions for the countermeasure relevance, corresponding crash modification factors, and countermeasure costs.The SNIP2 is computer software developed with close collaboration with the INDOT future users. It includes an updated crash and state road database. A user's manual describes on the necessary details of the software and various aspects of its use. Two example studies are also included in the manual to illustrate its use and to better presents the SNIP2 features.

Book Description
here, two well-known knee experts have assembled a group of leaders in the field to present a book encompassing the best techniques for total knee arthroplasty. Concise chapters cover indications, contraindications, complications, results, instrumentation, infection, preop planning, prosthetic choice, revision arthroplasty, and more -- with the emphasis on the best techniques and surgical "pearls". Supported by line drawings, intraoperative photographs and radiographs, this definitive volume will serve as the complete and quick reference on total knee arthroplasty.

Book Description
An edited volume with an international spectrum of contributors that places risk and resilience in health and social care in context. The chapters explore the issues of risk and resilience in health and social care, issues fundamental to some of the most complex decision making required by society, services, practitioners and members of the public. They look at issues of risk and resilience across the age spectrum, from children and young people to older adults. Three underpinning concepts are examined: location of responsibility and risk expertise; human rights and citizenship; agency and independence.

Book Description
After a brief account of the recent trends in science indicatiors research, the authors propose a coherent system of scientometric indicators. These indicators are based on the publication performance of each country in 8 science fields and reflect the versatility of the impact of the publication activity in the country in question. The special aim of the indicator system is to characterize and compare the contribution of research-intensive, medium-sized and small countries to the world's overall scientific research activity. Indicator values for 32 such countries are reported and evaluated. Relations to other economic, social and science indicators are discussed.This book is intended both as a data source and an analytic tool for specialists engaged in science policy, science management, science indicators research, scientometrics and other areas of science as well as a tool for practising research scientists.

Book Description
A rising median age at which PhD's receive their first research grant from the National Institutes of Health (NIH) is among the factors forcing academic biomedical researchers to spend longer periods of time before they can set their own research directions and establish there independence. The fear that promising prospective scientists will choose other career paths has raised concerns about the future of biomedical research in the United States. At the request of NIH, the National Academies conducted a study on ways to address these issues. The report recommends that NIH make fostering independence of biomedical researchers an agencywide goal, and that it take steps to provide postdocs and early-career investigators with more financial support for their own research, improve postdoc mentoring and establish programs for new investigators and staff scientists among other mechanisms.
