Script analysis for theatre : tools for interpretation, collaboration and production. by Knopf, Robert,1961-(CARDINAL)654301;
Script Analysis for Theatre: Tools for Interpretation, Collaboration and Production provides theatre students and emerging theatre artists with the tools, skills and a shared language to analyze play scripts, communicate about them, and collaborate with others on stage productions. Based largely on concepts derived from Stanislavski's system of acting and method acting, the book focuses on action - what characters do to each other in specific circumstances, times, and places - as the engine of every play. From this foundation, readers will learn to distinguish the big picture of a script, dissect and 'score' smaller units and moment-to-moment action, and create individualized blueprints from which to collaborate on shaping the action in production from their perspectives as actors, directors, and designers.

Preliminary engineering cost trends for highway projects / by North Carolina.Department of Transportation.Research and Analysis Group.(CARDINAL)272064; North Carolina State University.Department of Civil, Construction, and Environmental Engineering.(CARDINAL)307977;
Final report;Includes bibliographical references (pages 76-80).Preliminary engineering (PE) for a highway project encompasses two efforts: planning to minimize the physical, social, and human environmental impacts of projects and engineering design to deliver the best alternative. PE efforts begin years in advance of the project's construction letting, often five years or more. An efficient and accurate method to estimate PE costs would benefit transportation departments. Typically, departments estimate PE costs as a percentage of construction costs disregarding other project-specific parameters. By analyzing 461 North Carolina Department of Transportation bridge projects and 188 roadway projects let between 2001 through 2009, the research team developed statistical models linking variation in PE costs and PE duration with distinctive project parameters. The development of a user interface application aids agency users in executing the models to predict a project's PE cost ratio. Modeling strategies included multiple linear regression, hierarchical linear models, Dirichlet process linear models, and multilevel Dirichlet process linear models (MDPLM). The 461 bridge projects exhibited a mean PE cost ratio of 27.8% (ratio of PE cost over estimated construction cost) and a mean PE duration of 66.1 months. Mean PE cost ratio for the 188 roadway projects was 11.7% with a mean PE duration of 55.1 months. Project parameters utilized in the predictive models included project scope classification such as widening or new location, dimensional variables (project length, structure length, detour length, and number of spans); geographical region; and estimated costs for construction and right of way. The MDPLM minimized the mean absolute prediction error for bridges' PE cost ratio, but interpretation of variable effects and sensitivity is difficult because of the multilevel structure. Regression modeling results are also reported since sensitivity interpretation from them is more direct.

Reproducing racism : how everyday choices lock in white advantage / by Roithmayr, Daria,author.(CARDINAL)405455;
Includes bibliographical references (pages 159-183) and index.The more things change, the more they stay the same : some (incomplete and unsatisfying) explanations for persistent inequality -- Cheating at the starting line : how white racial cartels gained an early unfair advantage during Jim Crow -- Racial cartels in action : an in-depth look at historical racials cartels in housing and politics -- Oh dad, poor dad : how whites' early unfair advantage in wealth became self-reinforcing over time -- It's how you play the game : how whites created institutional rules that favored them over time -- Not what you know, but who you know : how social networks reproduce early advantage -- Please won't you be my neighbor? : How neighborhood effects reproduce racial segregation -- Locked in : how white advantage may now have become hard-wired into the system -- Reframing race : how the lock-in model helps us to think in new ways about racial inequality -- Unlocking lock-in : some general observations (and one or two suggestions) on dismantling lock-in."This book is designed to change the way we think about racial inequality. Long after the passage of civil rights laws and now the inauguration of our first black president, blacks and Latinos possess barely a nickel of wealth for every dollar that whites have. Why have we made so little progress? Legal scholar Daria Roithmayr provocatively argues that racial inequality lives on because white advantage functions as a powerful self-reinforcing monopoly, reproducing itself automatically from generation to generation even in the absence of intentional discrimination. Drawing on work in antitrust law and a range of other disciplines, Roithmayr brilliantly compares the dynamics of white advantage to the unfair tactics of giants like AT&T and Microsoft. With penetrating insight, Roithmayr locates the engine of white monopoly in positive feedback loops that connect the dramatic disparity of Jim Crow to modern racial gaps in jobs, housing and education. Wealthy white neighborhoods fund public schools that then turn out wealthy white neighbors. Whites with lucrative jobs informally refer their friends, who refer their friends, and so on. Roithmayr concludes that racial inequality might now be locked in place, unless policymakers immediately take drastic steps to dismantle this oppressive system. Daria Roithmayr is the George T. and Harriet E. Pfleger Professor of Law at the University of Southern California Gould School of Law. An internationally acclaimed legal scholar and activist, she is one of the country's leading voices on the legal analysis of structural racial inequality. Prior to joining USC, Professor Roithmayr advised Senator Edward Kennedy on the nominations of Clarence Thomas and David Souter, and taught law at the University of Illinois"--

Includes bibliographical references (pages 307-309).Introduction -- Preliminary screening of bridges for detailed evaluation -- Detailed evaluation of existing bridges -- Seismic retrofitting strategies -- Retrofit measures for bearings, seats, and expansion joints -- Retrofit measures for columns, cap beams, and joints -- Retrofit measures for foundations -- Retrofit measures for bridges on hazardous sites -- Retrofit measures using earthquake protective systems -- Appendices -- References.Task report;This manual is an interim revision of the Federal Highway Administration (FHWA) publication "Seismic Retrofitting Guidelines for Highway Bridges", which was published in 1983 as report number FHWA/RD-83/007. It describes an evaluation procedure for retrofitting seismically deficient highway bridges and outlines various measures to upgrade these structures. The guidance provided in this manual is comprehensive in nature and nationally applicable to bridges in different seismic zones. It includes a revised preliminary screening procedure; two methods of detailed evaluation (which include the capacity/demand ratio method and the lateral strength method); and expanded sections on retrofit measures for bearings, columns, footings, foundations, and soils. A new section on the application of seismic isolation to bridge retrofit is also included. The manual is termed an interim revision because the subject matter is still evolving at this time.Sponsored by Office of Engineering and Highway Operations R&D, Federal Highway Administration, under contract no.

Advances in weigh-in-motion using pattern recognition and prediction of fatigue life of highway bridges. by Gagarine, Nicolas.; Albrecht, Pedro.(CARDINAL)328724; United States.Federal Highway Administration.Office of Engineering & Highway Operations Research and Development,sponsor.(CARDINAL)286896; Turner-Fairbank Highway Research Center.(CARDINAL)286897; University of Maryland, College Park.Department of Civil Engineering.(CARDINAL)328723;
Includes bibliographical references (pages 37-40).Introduction -- Background on development of WIM+R system -- Field experiments -- Weigh-in-motion study -- Structural response study -- Pattern recognition study -- Conclusions and recommendations -- Appendices -- References.Final report;The two main objectives of the present study were to: (1) demonstrate the advantages of using the Weigh-in-Motion and Response (WIM+R) system to evaluate the fatigue life of existing bridges and (2) introduce pattern recognition methods in the analysis of WIM+R data. Four steel girder bridges were instrumented to obtain strain data at fatigue critical details, and at sections of maximum strain to compute the gross vehicle weight (GVW) of each truck. Two were simple spans, and two continuous spans. A comparative study of three of the four alternatives suggested by AASHTO showed that the fatigue life computed with direct measurements of the stress ranges were greater than those computed with the simplified approaches. The effect of secondary cycles was negligible for the four bridges. The damage equivalent secondary cycle factor for fatigue was defined. The applicability of three pattern recognition methods for WIM+R was investigated. The dynamic time warping, hidden Markov model, and feed forward neural network methods can classify trucks with the measured strain patterns alone.Sponsored by the Office of Engineering & Highway Operations R & D, and prepared by the Dept. of Civil Engineering, University of Maryland, under contract no.
