  • The theoretical metrics developed, such as genetic variance and heritability (Fisher, 1930; Wright, 1931), provided the quantitative standards necessary for the evolutionary synthesis. Further research has focused on the origin of genetic diversity, its maintenance and its role in evolution. Simple questions such as “who breeds with whom” initiated studies on the relatedness of populations.

  • This book is an exploration of the evolutionary process of natural hybridization. My motivation for writing this book comes from the view that crosses between genetically divergent individuals have a major influence on the evolution of some plant and animal species complexes. In particular, I want to examine the role that natural hybridization has as a creative force in organismal evolution. I realize that my emphasis on the "creative" aspect of natural hybridization could lead some to conclude that I believe that this is the only possible outcome from hybridization and gene exchange....

  • Evolution of global technologies has prompted increasing complexity of applications developed in both, the industry and the scientific research fields. These complexities are generally attributed to nonlinearities, poorly defined dynamics and absence of apriori information about the systems. Imprecision, uncertainties and vagueness in information about the system are also playing vital roles in enhancing the complexity of application.

  • As a research scientist in the area of human nutrition, I have observed a sea change in emphasis within my field over the past 10–15 years. There have always been dynamics within the subject: During the first half of the twentieth century, scientists grappled with discovering the essential micronutrients and with characterizing the biological effects of their deficiency. This interest in “too little” was supplanted in the mid-1980s by a preoccu- pation with too much—too much fat, too much sugar, and too much obesity.

  • Our planet is nowadays continuously monitored by powerful remote sensors operating in wide portions of the electromagnetic spectrum. Our capability of acquiring detailed information on the environment has been revolutionized by revealing its inner structure, morphology and dynamical changes. The way we now observe and study the evolution of the Earth’s status has even radically influenced our perception and conception of the world we live in.

  • The Invention of the Phase 21 Concept In 1992 SMG had to stop adding new items to the phase 2 work programme. It was nevertheless clear that there would be something after phase 2. Some proposed to call it ‘‘phase 3’’. This would of course have later caused some confusion with third generation. But the actual reason why SMG rejected this expression is that it would have suggested a phase 2/phase 3 transition similar to the phase 1/phase 2 transition, while it was thought that, for this further evolution, one should aim at a full cross phase compatibility....

  • This chapter develops illustrative applications, including the design of a contemporary SDR infrastructure product, the disaster-relief system. I. THE DESIGN PROCESS The implementation of SDR applications can be structured into an SDR design process. This process begins with the definition of a concept of operations (CONOPS), in which functions of the product are identified. The next stage, system definition, includes rapid prototyping and benchmarking. The third stage, system development, includes the implementation of hardware-software components. ...

  • What can business leaders learn from rock and roll? It’s a question that appears simple, yet it proved to be extraordinarily complex. The answer started as one that was entertaining (to us, and we hope to you), yet it yielded highly educational principles. The topic was conceptually intriguing, yet verbally challenging. These polarities of a seemingly contradictory paradigm excited us as we began talking to friends, professors, and business leaders ranging from frontline salespeople to CEOs about the Brands That Rock concept.

  • The evolutionary origins of nectaries and nectar are relatively obscure, but several researchers, working on a broad scale on the evolution of angiosperm families, have provided overviews of nectary incidence, diversity, origin, and function. Two contrasting examples below show how concepts regarding the origin of nectaries and nectar have been modified in the light of new information. Firstly, in his outline of the classification of the angiosperms, Armen Takhtajan (1980) gives a simple, concise statement on the purpose and origin of nectaries:...

  • Bearing the foregoing in mind, lived experiences have been carefully selected and synchronised with generic ideas and principles of project management. By starting with the evolution of project management, the objective was to locate the discipline in its historical context, thus creating awareness to the project manager that he/she will be practising within a community of professionals. This is followed by the definition of the concept of project, which concomitantly elucidates related terms to which the project manager will find recourse from time-to-time.
