Product Description

Despite the widespread use of the term “audience” in our popular culture, the meaning of ��audience� � is complex, and it has undergone significant historical shifts over time. Media Audiences explores the concept of media audiences from four broad perspectives, as �victims� of mass media, as market constructions and commodities, as users of media, and as producers and subcultures of mass media.

Product Description

The voices of birds have always been a source of fascination. Nature� s Music brings together some of the world’s experts on birdsong, to review the advances that have taken place in our understanding of how and why birds sing, what their songs and calls mean, and how they have evolved. All contributors have strived to speak, not only to fellow experts, but also to the general reader. The result is a book of readable science, richly illustrated with recordings and pictures of the sounds of birds.

Bird song is much more than just one behaviour of a single, particular group of organisms. It is a model for the study of a wide variety of animal behaviour systems, ecological, evolutionary and neurobiological. Bird song sits at the intersection of breeding, social and cognitive behaviour and ecology. As such interest in this book will extend far beyond the purely ornithological - to behavioural ecologists psychologists and neurobiologists of all kinds.

* The scoop on local dialects in birdsong
* How birdsongs are used for fighting and flirting
* The writers are all international authorities on their subject

Nature's Music: The Science of Birdsong Review

This volume brings together the findings of the dramatic bird song research in the last 50 years. The research was launched by W. H. Thorpe in the 1950s, but it was his student Peter Marler who turned the agenda into an explosion of work and exciting findings. Marler and his students have energized not only biology, but psychology, linguistics, and evolutionary biology. Key results are summarized in this huge volume, dedicated to the memory of the late Luis Baptista, one of Marler's early students.

Some particularly dramatic findings of the last 50 years include the widespread existence of learned song-dialects; the importance of learning in general; the ability of many birds to sing two notes at once; the many purposes to which song is put; and the degree to which birds are conscious of meanings and structures. Before the Marler revolution, biologists usually thought of birds as "birdbrains," driven solely by instinct or primitive stimulus-response learning. Now we know birds learn very complicated songs, often from other species, and plan ahead to accomplish their goals by varied communication strategies. They aren't as smart as humans or apes, but they are far smarter than we used to think we were. They continue to surprise us.

Bird song and bird society can be useful simple models for us; they show how relatively complex systems can evolve, and provide ideas for how human (proto-)language and society might have evolved a million, or a few million, years ago. This book does not get much into that realm of speculation, but some of the authors here (notably W. T. Fitch) have worked with linguists on these questions. We need more work on this. Moreover, humans and songbirds share true music; apes don't seem to have it. To understand how humans evolved musical competence, we have to look at avian models.

Two cautionary notes. First, this is a book for professionals; it won't be easily accessible to the general reader. Fortunately, one of the authors, Don Kroodsma, has filled the gap with his new book THE SINGING LIFE OF BIRDS. The second is that the recording quality of the CD's is uneven; the nightingales sure don't sound as good as they do in the woods of south France!

One chapter treats conservation issues; I wish it were longer and more comprehensive. Since Rachel Carson's classic book SILENT SPRING, Carson's worst fears have come to pass in much of the world. Just in the last five years, spring has become almost totally silent (in regard to bird song) at my house. Not only the pesticides she feared, but urbanization, global warming (fires, droughts...), and now West Nile virus are killing off the songbirds. The cover of the present book portrays a meadowlark. This formerly abundant bird has been reduced in numbers by about 99% in fast-urbanizing southern California since my youth, and is now a genuinely rare bird over almost all its range. The younger authors of this book may live to see their subject matter go extinct. My younger children have grown up in a song-deprived world; my grandchildren hear almost no bird songs at all, except on the wildlife programs they love to watch on TV.

Thus, I would very, very, very strongly urge all students of bird song to get out there and document wild birds and their songs, while there is time. Much of this book deals with experiments on domesticated birds. Such work is very valuable, but we desperately need to get the wild songs documented while yet we can.

Product Description

This is the first book primarily about the satellite payload of satellite communications systems. It represents a unique combination of practical systems engineering and communications theory. It tells about the satellites in geostationary and low-earth orbits today, both the so-called bent-pipe payloads and the processing payloads. The on-orbit environment, mitigated by the spacecraft bus, is described. The payload units (e.g. antennas and amplifiers), as well as payload-integration elements (e.g. waveguide and switches) are discussed in regard to how they work, what they do to the signal, their technology, environment sensitivity, and specifications. At a higher level are discussions on the payload as an entity: architecture including redundancy; specifications--what they mean, how they relate to unit specifications, and how to verify; and specification-compliance analysis ( � budgets� ) with uncertainty. Aspects of probability theory handy for calculating and using uncertainty and variation are presented. The highest-level discussions, on the end-to-end communications system, start with a practical introduction to physical-layer communications theory. Atmospheric effects and interference on the communications link are described. A chapter gives an example of optimizing a multibeam payload via probabilistic analysis. Finally, practical tips on system simulation and emulation are provided. The carrier frequencies treated are 1 GHz and above. Familiarity with Fourier analysis will enhance understanding of some topics. References are provided throughout the book for readers who want to dig deeper.

Payload systems engineers, payload proposal writers, satellite-communications systems designers and analysts, and satellite customers will find that the book cuts their learning time. Spacecraft-bus systems engineers, payload unit engineers, and spacecraft operators will gain insight into the overall system. Students in systems engineering, microwave engineering, communications theory, probability theory, and communications simulation and modelling will find examples to supplement theoretical texts.

Satellite Communications Payload and System Review

As a practicing engineer and business executive, I ordered this book when I needed to get back up to speed, quickly, on the latest developments in satellite communications after working in the submarine fiber optic cable world for a few years. Her focus on comm systems and subsystems (as noted by the previous reviewer) gave me a slightly different and 'fresher' perspective than most of my older textbooks on the subject-- many of which are also excellent-- yet still provided the fundamental body of up-to-date technical knowledge I needed. Dr. Braun's book turned out to be an excellent investment in both money and time, and I highly recommend it.

Product Description

Most security books are targeted at security engineers and specialists. Few show how build security into software. None breakdown the different concerns facing security at different levels of the system: the enterprise, architectural and operational layers. Security Patterns addresses the full spectrum of security in systems design, using best practice solutions to show how to integrate security in the broader engineering process.

• Essential for designers building large-scale systems who want best practice solutions to typical security problems
• Real world case studies illustrate how to use the patterns in specific domains

Security Patterns: Integrating Security and Systems Engineering (Wiley Software Patterns Series) Review

I read six books on software security recently, namely "Writing Secure Code, 2nd Ed" by Michael Howard and David LeBlanc; "19 Deadly Sins of Software Security" by Michael Howard, David LeBlanc, and John Viega; "Software Security" by Gary McGraw; "The Security Development Lifecycle" by Michael Howard and Steve Lipner; "High-Assurance Design" by Cliff Berg; and "Security Patterns" by Markus Schumacher, et al. Each book takes a different approach to the software security problem, although the first two focus on coding bugs and flaws; the second two examine development processes; and the last two discuss practices or patterns for improved design and implementation. My favorite of the six is Gary McGraw's, thanks to his clear thinking and logical analysis. The other five are still noteworthy books. All six will contribute to the production of more security software.

It's important to recognize that "Security Patterns" (SP) is not as narrowly focused as a similar book, Cliff Berg's "High-Assurance Design." SP applies to code, but also to enterprise architecture, and even non-IT scenarios. A case study involving protecting a museum runs throughout much of the text, for example. SP introduces several helpful concepts as well, such as security "properties" (CIA), "services" (authentication, authorization, accounting, auditing, non-repudiation), "approaches" (planning, prevention, detection, response), and "mechanisms" (access control, etc.).

The first part of SP explains the important of patterns, which I found useful as a non-professional programmer. I realized that patterns are significant not just because they help define a solution, but also because they can assist in properly scoping the problem (p 35). However, these patterns do not provide code samples. It's more conceptual than actionable.

Similar to Microsoft's books on secure software development, I thought SP suffered from confusing terminology. For example, SP decides to include "accountability" as a security "property". I am not sure this qualifies as a property, since it's really only needed to know who violated one of the CIA properties. CIA violations should be labeled disclosure, corruption, and denial of service.

SP stumbles when it discusses "threat assessment," defining terms like "threat source" (which should be just "threat"), "threat action" (i.e., "attack"), and "threat consequence" (really an "incident" or "violation"). In several places (pp 116. 118) SP ignores the fact that threats and vulnerabilities are independent aspects of security; they are not synonyms.

Although SP's pattern approach is interesting, sometimes the execution is weak or incorrect. I found the hand-drawn stick figures in ch 9 to be laughable. I cringed when I read about "today's more popular remote shell, /usr/bin/rsh". The authors didn't know what they were talking about when discussing firewalls, either. Packet-filtering firewalls don't just work by inspecting "addresses," and the BSD Packet Filter is a stateful packet filter, not an address-inspecting packet filter. I thought the architecture diagrams were far too simplistic and in some cases poor, such as showing a mainframe and a public Web server in the same network segment.

Overall, I think the idea of using security patterns to provide tools for developers and architects is powerful. Perhaps a second edition or later books will better execute on this idea. I still think SP deserves four stars for breaking fairly new ground with this approach, and using non-digital examples to emphasize concepts applicable to information security problems.
