For millennia, humans waged war on land and sea. The 20th century
opened the skies and the stars, introducing air and space as
warfare domains. Now, the 21st century has revealed perhaps the
most insidious domain of all: cyberspace, the fifth domain. A realm
free of physical boundaries, cyberspace lies at the intersection of
technology and psychology, where one cannot see one's enemy, and
the most potent weapon is information. The third book in the Great
Power Competition series, Cyberspace: The Fifth Domain, explores
the emergence of cyberspace as a vector for espionage, sabotage,
crime, and war. It examines how cyberspace rapidly evolved from a
novelty to a weapon capable of influencing global economics and
overthrowing regimes, wielded by nation-states and religious
ideologies to stunning effect. Cyberspace: The Fifth Domain offers
a candid look at the United States' role in cyberspace, offering
realistic prescriptions for responding to international cyber
threats on the tactical, strategic, and doctrinal levels, answering
the questions of how can we respond to these threats versus how
should we respond? What are the obstacles to and consequences of
strategic and tactical response options? What technological
solutions are on the horizon? Should the U.S. adopt a more
multi-domain offensive posture that eschews the dominant "cyber vs.
cyber" paradigm? To answer these questions, experts examine the
technological threats to critical infrastructure; cyber operations
strategy, tactics, and doctrine; information influence operations;
the weaponization of social media; and much more.

"The authors of this book contend that the civil service system,
which was devised to create a uniform process for recruiting
high-quality workers to government, is no longer uniform or a
system. Nor does it help government find and retain the workers it
needs to build a government that works. The current civil service
system was designed for a government in which federal agencies
directly delivered most public services. But over the last
generation, privatization and devolution have increased the number
and importance of government's partnerships with private companies,
nonprofit organizations, and state and local governments.
Government workers today spend much of their time managing these
partnerships, not delivering services, and this trend will only
accelerate in the future. The authors contend that the current
system poorly develops government workers who can effectively
manage these partnerships, resulting too often in a gap between
promise and performance. This short, lively, and bipartisan volume,
authored by the nation's leading experts on government management,
describes what the government of the future will look like, what it
will need to work well, and how in particular the nation can build
the next generation of workers required to lead it. "
When data is collected on failure or survival a list of times is
obtained. Some of the times are failure times and others are the
times at which the subject left the experiment. These times both
give information about the performance of the system. The two types
will be referred to as failure and censoring times (cf. Smith
section 5). * A censoring time, t, gives less information than a
failure time, for it is * known only that the item survived past t
and not when it failed. The data is tn and of censoring thus
collected as a list of failure times t , . . . , l * * * times t ,
t , . . . , t * 1 z m 2. 2. Classical methods The failure times are
assumed to follow a parametric distribution F(t;B) with and
reliability R(t;B). There are several methods of estimating density
f(t;B) the parameter B based only on the data in the sample without
any prior assumptions about B. The availability of powerful
computers and software packages has made the method of maximum
likelihood the most popular. Descriptions of most methods can be
found in the book by Mann, Schafer and Singpurwalla (1974). In
general the method of maximum likelihood is the most useful of the
classical approaches. The likelihood approach is based on
constructing the joint probability distrilmtion or density for a
sample.

How can government leaders build, sustain, and leverage the
cross-organizational collaborative networks needed to tackle the
complex interagency and intergovernmental challenges they
increasingly face? Tackling Wicked Government Problems: A Practical
Guide for Developing Enterprise Leaders draws on the experiences of
high-level government leaders to describe and comprehensively
articulate the complicated, ill-structured difficulties they face -
often referred to as "wicked problems" - in leading across
organizational boundaries and offers the best strategies for
addressing them. Tackling Wicked Government Problems explores
howenterprise leaders use networks of trusted, collaborative
relationships to respond and lead solutions to problems that span
agencies. It also offers several approaches fortranslating social
network theory into practical approaches for these leaders to build
and leverage boundary-spanning collaborative networks and achieve
real mission results. Finally, past and present government
executives offer strategies for systematically developing
enterprise leaders. Taken together, these essays provide a way
forward for a new cadre of officials better equipped to tackle
government's twenty-first-century wicked challenges.
This ready-reference contains valuable insight for the engineer
faced with design and manufacture decisions. A continuation of
Sanders' two volumes on maintenance and repair, this volume
represents the first in a subsequent two volume set on mechanical
design and manufacture, completing the remaining portion of his
popular seminar. In this volume, Sanders turns his focus to design
options and the challenges faced in selecting and arranging the
components to optimize unit performance efficiency, reliability,
and safety, providing the reader with the necessary information to
evaluate the performance, refurbishment, and upgrading of a unit.
This book lets you: select the right components and find optimal
unit arrangement; understand the mechanical design and development
process; and, organize and prepare performance testing.
This monograph contains four chapters, each of which provides a
different perspective on biopesticides. Chapter One concerns the
use of biopesticides in sustainable agriculture, including the
interactions between biopesticides and chemical pesticides,
production issues, and opportunities for future research. Chapter
Two describes the bottom-up approach for using Bacillus
thuringiensis (Bt) as a biopesticide and for enhancing host plant
resistance against major foliage feeders through deployment of
suitable cry genes. Chapter Three reviews strategies for mitigating
the spread of Bt resistance and improving insecticidal activity
against Bt-susceptible pests. Lastly, Chapter Four aims to revise,
debate, and evaluate the effects of Bt as phosphate solubilizing
and phosphorus uptake by plant establishment.
