This book is about stochastic Petri nets (SPNs), which have proven to be a popular tool for modelling and performance analysis of complex discrete-event stochastic systems. The focus is on methods for modelling a system as an SPN with general firing times and for studying the long-run behavior of the resulting SPN model using computer simulation. Modelling techniques are illustrated in the context of computer, manufacturing, telecommunication, workflow, and transportation systems. The simulation discussion centers on the theory that underlies estimation procedures such as the regenerative method, the method of batch means, and spectral methods.Tying these topics together are conditions on the building blocks of an SPN under which the net is stable over time and specified estimation procedures are valid. In addition, the book develops techniques for comparing the modelling power of different discrete-event formalisms. These techniques provide a means for making principled choices between alternative modelling frameworks and also can be used to extend stability results and limit theorems from one framework to another. As an overview of fundamental modelling, stability, convergence, and estimation issues for discrete-event systems, this book will be of interest to researchers and graduate students in Applied Mathematics, Operations Research, Applied Probability, and Statistics. This book also will be of interest to practitioners of Industrial, Computer, Transportation, and Electrical Engineering, because it provides an introduction to a powerful set of tools both for modelling and for simulation-based performance analysis. Peter J. Haas is a member of the Research Staff at the IBM Almaden Research Center in San Jose, California. He also teaches Computer Simulation at Stanford University and is an Associate Editor (Simulation Area) for Operations Research.
This volume comprises fifteen essays classified in three major sections. Some of these essays raise theoretical and methodological issues while others focus on specific topics. The time span ranges from late biblical period to the present. The volume reflects the current thought of some of the major scholars in the field in various shapes and contexts as well as from a variety of perspectives: inner-biblical, qumranic, New Testament, various rabbinic literature (targumic, midrashic, halachic, and Medieval kabalistic), and some modern interpretation. The essays reflect the contemporary thought of some of the foremost scholars in the field of biblical exegesis from a variety of standpoints, moving the biblical exegesis well beyond its conventional limits, and enriching the knowledge and deepening the understanding of the readers.
Where many textbooks on policy research focus on methodological and statistical theories, leaving students to wonder how they will apply those theories to future policy positions, this innovative textbook takes theories of policy research and puts them into practice, demystifying the subject by translating it into real-world situations in which students can actively engage. Beginning with an orientation and overview of policy research, outlining the processes of policy analysis and evaluation from start to finish, Applied Policy Research, 2e walks students through an examination of case studies to demonstrate how these theories play out in real policy situations. New to this edition: A rewritten Part I that includes several new chapters incorporating the latest developments in applicable policy research design, implementation, and products to provide a framework for conducting policy research. A matrix at the start of Part II to easily identify how each of the fifteen case-study chapters correspond with concepts and topics presented in Part I, showing the reader where to look for a specific real-life example of a given topic or concept. Each case is drawn from real instances of policy research to provide students with an opportunity to consider and learn how to grapple with the challenges posed by the needs of public programs and agencies. Cases include local, state, and nonprofit agencies as well as federal-state-local intergovernmental "hybrids." Each chapter is presented in a uniform format: (1) a detailed description of a policy research problem; (2) a discussion of the unique challenges posed by the problem; (3) a description of the policy research techniques used; (4) a summary of the outcomes or conclusions associated with the research as it was conducted; and (5) conclusions about the implications or lessons for policy research. Illustrative figures help students understand the stages of policy research, and end-of-chapter tools such as discussion questions, assignments and activities, and case studies "at a glance" help students master not only the particulars of each case but the broader skills needed in future research. Applied Policy Research, Second Edition will be essential reading in all policy research courses with a focus on practical outcomes and student preparation for public service.

The new edition of this influential work updates and expands the scope of the original, including more sustained analyses of individual films, from The Birth of a Nation to The Wolf of Wall Street. An interdisciplinary exploration of the relationship between American politics and popular films of all kinds-including comedy, science fiction, melodrama, and action-adventure-Projecting Politics offers original approaches to determining the political contours of films, and to connecting cinematic language to political messaging. A new chapter covering 2000 to 2013 updates the decade-by-decade look at the Washington-Hollywood nexus, with special areas of focus including the post-9/11 increase in political films, the rise of political war films, and films about the 2008 economic recession. The new edition also considers recent developments such as the Citizens United Supreme Court decision, the controversy sparked by the film Zero Dark Thirty, newer generation actor-activists, and the effects of shifting industrial financing structures on political content. A new chapter addresses the resurgence of the disaster-apocalyptic film genre with particular attention paid to its themes of political nostalgia and the turn to global settings and audiences. Updated and expanded chapters on nonfiction film and advocacy documentaries, the politics of race and African-American film, and women and gender in political films round out this expansive, timely new work. A companion website offers two additional appendices and further materials for those using the book in class.

Endorsements: "This book is a study of the Holocaust as problem in ethical theory. How could a whole society participate in an ethic of mass torture and genocide for over a decade without opposition from responsible political, legal, medical, or religious leaders? How does a society create and adopt its ethical norms? This is a study in narrative ethics at its best, yet the author's purpose is to discover how a people redefined evil to the degree that they committed heinous atrocities that were reprehensible under normal circumstances." --Guy Greenfield, Southwestern Journal of Theology "Peter Haas gives us a good overall description of the Holocaust, the way the Nazis and their myriad collaborators treated the Jews. The book . . . is well formulated and well written. It makes a good one-volume introduction to the Holocaust." --Frederick K. Wentz, Lutheran Quarterly "Peter Haas urges us to recognize ourselves in the perpetrators of the Holocaust. . . . In the course of setting forth his position, the author offers a concise and wonderfully accessible account of the formation of German political culture from Bismarck through Hitler. . . . Morality After Auschwitz is a serious book that should provoke long thoughts, and perhaps useful disputes, about the power of ethics to shape political cultures." --First Things
Synopses for Massive Data: Samples, Histograms, Wavelets, Sketches describes basic principles and recent developments in building approximate synopses (i.e., lossy, compressed representations) of massive data. Such synopses enable approximate query processing, in which the user's query is executed against the synopsis instead of the original data. The monograph focuses on the four main families of synopses: random samples, histograms, wavelets, and sketches. A random sample comprises a "representative" subset of the data values of interest, obtained via a stochastic mechanism. Samples can be quick to obtain, and can be used to approximately answer a wide range of queries. A histogram summarizes a data set by grouping the data values into subsets, or "buckets," and then, for each bucket, computing a small set of summary statistics that can be used to approximately reconstruct the data in the bucket. Histograms have been extensively studied and have been incorporated into the query optimizers of virtually all commercial relational DBMSs. Wavelet-based synopses were originally developed in the context of image and signal processing. The data set is viewed as a set of M elements in a vector - i.e., as a function defined on the set {0, 1, 2, . . ., M-1} - and the wavelet transform of this function is found as a weighted sum of wavelet "basis functions." The weights, or coefficients, can then be "thresholded," for example, by eliminating coefficients that are close to zero in magnitude. The remaining small set of coefficients serves as the synopsis. Wavelets are good at capturing features of the data set at various scales. Sketch summaries are particularly well suited to streaming data. Linear sketches, for example, view a numerical data set as a vector or matrix, and multiply the data by a fixed matrix. Such sketches are massively parallelizable. They can accommodate streams of transactions in which data is both inserted and removed. Sketches have also been used successfully to estimate the answer to COUNT DISTINCT queries, a notoriously hard problem. Synopses for Massive Data describes and compares the different synopsis methods. It also discusses the use of AQP within research systems, and discusses challenges and future directions. It is essential reading for anyone working with, or doing research on massive data.
