The Animal Production and Health Section of the Joint FAO/IAEA Division of
Nuclear Techniques in Food and Agriculture recognises that the trend towards
intensification of livestock production in developing countries presents both opportunities
and challenges. The potential opportunities are the flow-on benefits to the
producers and local economy while the potential challenges are the flow-on costs
to the environment, animal health and welfare.
We take a critical look at the relationship between the security of cryptographic schemes in the Random Oracle Model, and the security of the schemes that result from implementing the random oracle by so called \cryptographic hash functions". The main result of this paper is a negative one: There exist signature and encryption schemes that are secure in the Random Oracle Model, but for which any implementation of the random oracle results in insecure schemes.
This book is structured in three parts. In Part I, we aim to sensitise you,
the reader, to the complex issues that challenge qualitative researchers
at the planning stage of their projects. In Part II, the challenge of using
different methodologies in practice is critically explored by 15 authors
who share their individual research experiences. Part III examines the
choices we make when we evaluate and present research.
We hope you will find this book both exciting and helpful. Inevitably,
there are many gaps in terms of topics and issues covered, and methodologies
From the very beginning of the transition from the traditional purchasing system reviews to the
redesigned assessment approach that replaced them, it was understood that further refinement
and continuous improvement was planned. Consistent with that long-term strategy, and building
on the originally redesigned federal purchasing assessments, the business system assessment
models of the PEAmembers have evolved to be more aligned with the Balanced Scorecard
(BSC) approach to performance measurement and management, which is currently in use by
many “world class” private corporations.
Interpreting, like playing chess, is a game of problem solving, evaluation, critical
thinking, intuition and forecasting. Every game is different and each game is a challenge,
which requires interpreters, to unceasingly develop knowledge and experience. It is
disciplined study and repeated practice of many techniques and skills that bring victory to
the interpreter. Apart from basic requirements of language mastery and culture sensitivity,
there are quite a few skills that need to be acquired for successful interpreting. One of
them is note-taking skill....
Over the course of a few short years, electronic business has advanced from a buzzword to a thriving new channel for the delivery of goods and services and the mediation of financial transactions, shaping the destiny of numerous contemporary enterprises and significantly affecting entire economies worldwide.
They use geological and distribution
data on the island’s 1,284 plant genera and more than 2,000 endemic plant taxa to
identify 19 biomes there, and they describe complex conservation challenges. The next
chapter by Benny Chan and Pei-Fen Lee explores the biogeography of the barnacles of
Taiwan, relating taxon distributions to coastal geomorphology and the complex array
of oceanic currents around the island. Global climate changes in ocean water
temperature may permit southerly, warmwater taxa to expand northward, invading
habitat presently occupied by coldwater taxa....
The number one concern of start-up entrepreneurs and growing small business
owners and managers is how to finance their venture. When the personal
financial resources of the entrepreneur are exhausted, when the
tradition of going to family and friends for “cradle equity” has been thoroughly
“worked,” and when incurring personal debt from a bank for a loan
is no longer a viable option, then raising private capital can be one of the
toughest challenges for many entrepreneurs.
For the philosopher of history, G.W.F. Hegel, the fundamental challenge for any
student of societal evolution is to apprehend in thought the spirit of the age (or the
zeitgeist)—i.e., to understand the motive force of change while it is still at work
(Lauer, 1974). Catching the zeitgeist ‘in the act,’ so to speak, is a matter of practical
importance; for gaining such an understanding would seem to be a necessary,
if not sufficient, condition for successfully shaping ‘for the better’ any future state
of affairs. Hegel does not give us much cause for optimism here.
A gender audit is essentially a “social audit”, and belongs to the category of “quality audits”,
which distinguishes it from traditional “ﬁ nancial audits”. It considers whether internal practices
and related support systems for gender mainstreaming are effective and reinforce each other and
whether they are being followed. It establishes a baseline; identiﬁ es critical gaps and challenges;
and recommends ways of addressing them, suggesting possible improvements and innovations.
It also documents good practices towards the achievement of gender equality.
Space research is one of the most evocative and challenging fields of human endeavour.
In the half-century that has elapsed since the beginning of the space age, we
have been exposed to wonders beyond the imagination of even the most visionary of
science fiction writers. We have peered deep into the Universe and studied physics
that we can never duplicate on the Earth. We have begun to understand our own
Sun, and the flow of energy outward through the Solar System that is fundamental
to our existence.
This book was born from our combined years exploring the use of optically stimulated
luminescence (OSL) in different areas of radiation dosimetry with a seemingly unending
curiosity about the physics of the process and our aspirations and dreams concerning
potential applications. We wished to learn about and understand the challenges presented
by the many different areas of dosimetry and how OSL could play a useful role and, of
course, we hoped that we would make meaningful contributions to the field.
The development and writing of this report presented considerable challenges in terms of both the
study schedule and the need to avoid conveying sensitive U.S. vulnerabilities to potential adversaries.
Meeting both challenges has been difficult for the study committee and staff, but every effort was made
to respond to the stated need of the Technology Warning Division of the Defense Intelligence Agency
(DIA) for maximum openness.
I wish to express my appreciation to the members of the committee for their contributions to the
preparation of this report.
This informative new book explains, in meticulous detail, what is known scientifically about the effectiveness of complementary and alternative medicine therapies including nutritional, botanical, homeopathic and psychospiritual for HIV/AIDS. The special research methodology challenges involved in the scientific evaluation of complementary and alternative medicine are discussed in depth, and the authors offer valuable new insights into the complex pathogenesis of AIDS.
Project, IT, and change management are not entirely distinct disciplines or methodolo-
gies. The concepts, activities, and outputs in one discipline have parallel—and some-
times identical—features in the other two. We argue that to optimally plan and execute
HIT projects in HDOs requires all three adopted in concert. In this book, we combined
these standards and best practices to create an integrated project, IT, and change man-
Success with HIT projects is never a guarantee.
There is an important lesson that may be inferred from Jason's book. From his descriptions of project
management methodologies it is clear that what Jason has in mind is the "project life cycle" or, as we
prefer to call it, the "project life span". After all, the project life span is defined as: "The complete set of
time periods through which a project passes sequentially in a logical and orderly manner". Further, a
project may be defined as: "A process or undertaking that encompasses an entire set of activities having
. . . well defined objectives" and a process...
Although the vision of P2P systems is grand, the technical challenges associated with them are immense, and as a
result the realization of the vision has been elusive. Because the membership in the system is ad-hoc and dynamic, it is
very difﬁcult to predict or reason about the location and quality of the system’s resources. For example, the placement
of data in content-sharing systems is often na¨ ıve: data placement is largely demand driven, with little regard given to
network bandwidth, load, or historical trustworthiness of the peer on which the data is placed.
A key component of the quality of pharmaceutical drugs is the control of
impurities. It is important to identify and quantify levels of impurities that may
be present to provide safe, effective and well-controlled medicines. The measurement
and identification of impurities to today’s standards presents significant
challenges to the analytical chemist.
This National Research Council (NRC) study, commissioned
by the U.S. Department of Defense (DOD) in response
to a mandate from Congress, addresses the question
of whether there are alternatives to antipersonnel landmines
(APL)—including technologies, tactics, and operational concepts.
The study was conducted at an interesting historical
juncture, when the United States is at peace and, at the same
time, the number of new technologies rich in military possibilities
is unprecedented. The convergence of these two factors
presents the U.S.
