  • 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 represented.

  • 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....

  • 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.

  • 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- agement methodology. 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.

  • 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.
