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."

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.
