Download or read book The Practice of Citizenship written by Derrick R. Spires and published by University of Pennsylvania Press. This book was released on 2019-02-08 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the years between the American Revolution and the U.S. Civil War, as legal and cultural understandings of citizenship became more racially restrictive, black writers articulated an expansive, practice-based theory of citizenship. Grounded in political participation, mutual aid, critique and revolution, and the myriad daily interactions between people living in the same spaces, citizenship, they argued, is not defined by who one is but, rather, by what one does. In The Practice of Citizenship, Derrick R. Spires examines the parallel development of early black print culture and legal and cultural understandings of U.S. citizenship, beginning in 1787, with the framing of the federal Constitution and the founding of the Free African Society by Absalom Jones and Richard Allen, and ending in 1861, with the onset of the Civil War. Between these two points he recovers understudied figures such as William J. Wilson, whose 1859 "Afric-American Picture Gallery" appeared in seven installments in The Anglo-African Magazine, and the physician, abolitionist, and essayist James McCune Smith. He places texts such as the proceedings of black state conventions alongside considerations of canonical figures such as Frances Ellen Watkins Harper and Frederick Douglass. Reading black print culture as a space where citizenship was both theorized and practiced, Spires reveals the degree to which concepts of black citizenship emerged through a highly creative and diverse community of letters, not easily reducible to representative figures or genres. From petitions to Congress to Frances Harper's parlor fiction, black writers framed citizenship both explicitly and implicitly, the book demonstrates, not simply as a response to white supremacy but as a matter of course in the shaping of their own communities and in meeting their own political, social, and cultural needs.

Download or read book Applied Econometrics with R written by Christian Kleiber and published by Springer Science & Business Media. This book was released on 2008-12-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: R is a language and environment for data analysis and graphics. It may be considered an implementation of S, an award-winning language initially - veloped at Bell Laboratories since the late 1970s. The R project was initiated by Robert Gentleman and Ross Ihaka at the University of Auckland, New Zealand, in the early 1990s, and has been developed by an international team since mid-1997. Historically, econometricians have favored other computing environments, some of which have fallen by the wayside, and also a variety of packages with canned routines. We believe that R has great potential in econometrics, both for research and for teaching. There are at least three reasons for this: (1) R is mostly platform independent and runs on Microsoft Windows, the Mac family of operating systems, and various ?avors of Unix/Linux, and also on some more exotic platforms. (2) R is free software that can be downloaded and installed at no cost from a family of mirror sites around the globe, the Comprehensive R Archive Network (CRAN); hence students can easily install it on their own machines. (3) R is open-source software, so that the full source code is available and can be inspected to understand what it really does, learn from it, and modify and extend it. We also like to think that platform independence and the open-source philosophy make R an ideal environment for reproducible econometric research.

Download or read book Clinical Practice Guidelines We Can Trust written by Institute of Medicine and published by National Academies Press. This book was released on 2011-06-16 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in medical, biomedical and health services research have reduced the level of uncertainty in clinical practice. Clinical practice guidelines (CPGs) complement this progress by establishing standards of care backed by strong scientific evidence. CPGs are statements that include recommendations intended to optimize patient care. These statements are informed by a systematic review of evidence and an assessment of the benefits and costs of alternative care options. Clinical Practice Guidelines We Can Trust examines the current state of clinical practice guidelines and how they can be improved to enhance healthcare quality and patient outcomes. Clinical practice guidelines now are ubiquitous in our healthcare system. The Guidelines International Network (GIN) database currently lists more than 3,700 guidelines from 39 countries. Developing guidelines presents a number of challenges including lack of transparent methodological practices, difficulty reconciling conflicting guidelines, and conflicts of interest. Clinical Practice Guidelines We Can Trust explores questions surrounding the quality of CPG development processes and the establishment of standards. It proposes eight standards for developing trustworthy clinical practice guidelines emphasizing transparency; management of conflict of interest ; systematic review-guideline development intersection; establishing evidence foundations for and rating strength of guideline recommendations; articulation of recommendations; external review; and updating. Clinical Practice Guidelines We Can Trust shows how clinical practice guidelines can enhance clinician and patient decision-making by translating complex scientific research findings into recommendations for clinical practice that are relevant to the individual patient encounter, instead of implementing a one size fits all approach to patient care. This book contains information directly related to the work of the Agency for Healthcare Research and Quality (AHRQ), as well as various Congressional staff and policymakers. It is a vital resource for medical specialty societies, disease advocacy groups, health professionals, private and international organizations that develop or use clinical practice guidelines, consumers, clinicians, and payers.
