Most contemporary versions of moral realism are beset with difficulties. Many of these difficulties arise because of a faulty conception of the nature of goodness. Goodness, God, and Evil lays out and defends a new version of moral realism that re-conceives the nature of goodness.

Alexander argues that the adjective 'good' is best thought of as an attributive adjective and not as a predicative one. In other words, the adjective 'good' logically cannot be detached from the noun (or noun phrase) that it modifies. It is further argued that this conception of the function of the adjective implies that recent attempts to provide necessary a posteriori identities between goodness and something else must fail.

The convertibility of being and goodness, the privation theory of evil, a denial of the fact-value distinction, human nature as the ground of human morality and even a novel argument for the existence of God are some of the implications of the account of goodness that Alexander offers.

Nature's Machines: An Introduction to Organismal Biomechanics presents the fundamental principles of biomechanics in a concise, accessible way while maintaining necessary rigor. It covers the central principles of whole-organism biomechanics as they apply across the animal and plant kingdoms, featuring brief, tightly-focused coverage that does for biologists what H. M. Frost's 1967 Introduction to Biomechanics did for physicians. Frequently encountered, basic concepts such as stress and strain, Young's modulus, force coefficients, viscosity, and Reynolds number are introduced in early chapters in a self-contained format, making them quickly available for learning and as a refresher. More sophisticated, integrative concepts such as viscoelasticity or properties of hydrostats are covered in the later chapters, where they draw on information from multiple earlier sections of the book. Animal and plant biomechanics is now a common research area widely acknowledged by organismal biologists to have broad relevance. Most of the day-to-day activities of an animal involve mechanical processes, and to the extent that organisms are shaped by adaptive evolution, many of those adaptations are constrained and channelized by mechanical properties. The similarity in body shape of a porpoise and a tuna is no coincidence. Many may feel that they have an intuitive understanding of many of the mechanical processes that affect animals and plants, but careful biomechanical analyses often yield counterintuitive results: soft, squishy kelp may be better at withstanding pounding waves during storms than hard-shelled mollusks; really small swimmers might benefit from being spherical rather than streamlined; our bones can operate without breaking for decades, whereas steel surgical implants exhibit fatigue failures in a few months if not fully supported by bone.

The world is becoming more hazardous as natural and social processes combine to create complex situations of increased vulnerability and risk. There is increasing recognition that this trend is creating exigencies that must be dealt with. The common approach is to delegate the task of preparing an emergency plan to someone. Often that person is expected to get on with job but rarely is the means and instruction of how to write such a plan provided to them. There are a host of instances in which the letter of the law, not the spirit, is honoured by providing a token plan of little validity. David Alexander provides, in this book, the assistance needed to write an emergency plan. It is a practical 'how to' manual and guide aimed at managers in business, civil protection officers, civil security officials, civil defence commanders, neighbourhood leaders and disaster managers who have been tasked with writing, reviewing or preparing emergency plans for all kinds of emergency, disaster or catastrophe. He takes the reader through the process of writing an emergency plan, step by step, starting with the rationale and context, before moving on through the stages of writing and activating a basic, generic emergency plan and concludes with information on specific kinds of plan, for example, for hospitals and cultural heritage sites. This practical guide also provides a core for postgraduate training in emergency management and has been written in such a way that it is not tied to the legal constraints of any particular jurisdiction.

From airplanes to birds, the phenomenon of flight has always amazed and mystified humans. Therefore, it is unsurprising that scientists have invested a substantial amount of research into unraveling the secrets of flight evolution. Over the course of the past decade, the science of flight evolution has recently experienced a research renaissance, most of the information has been confined to the ivory tower of academia. In On the Wing, David Alexander delves into the evolution of flight in each of the four animal groups that evolved powered flight: insects, pterosaurs, birds, and bats. Alexander presents and compares each group's evolutionary history, including diversification and partial or complete extinction, especially as related to flight. The evolution of flight in animals is fascinating story riddled with scientific controversy and colorful characters, from the incredible Archaeopteryx to the recently-discovered feathered dinosaur Microraptor. Chapter topics include aerodynamics, comparisons and contrasts among the powered flyers, and the ultimate evolution away from flight. Alexander even examines the surprisingly diverse group of gliding animals, including squirrels, snakes, and ants. Through rigorous yet accessible writing, Alexander offers a comprehensive and engaging account of the evolution of flight, from dinosaurs to modern birds. On the Wing will delight and inform everyone from bird lovers to dinosaur enthusiasts, and offers key insights into the perpetual mystery of flight.

David E. Alexander's fascination with the many animals and plants that have harnessed the air is evident in "Nature's Flyers: Birds, Insects, and the Biomechanics of Flight," a detailed account of our current scientific understanding of the primary aspects of flight in nature.

Instead of relying on elaborate mathematical equations, Alexander explains the physical basis of flight with sharp prose and clear diagrams. Drawing upon bats, birds, insects, pterosaurs, and even winged seeds, he details the basic operating principles of wings and then moves progressively through more complex modes of animal flight, including gliding, flapping, and maneuvering. In addition to summarizing the latest thinking about flight's energy costs, Alexander presents a holistic view of flight and its ramifications as he explores the ecology and evolution of flying animals, addressing behaviorally important topics such as migration and navigation. With somewhat surprising answers, the author then concludes his study by examining the extent to which natural flight has been inspiring or instructive for the architects of human flight--airplane designers and engineers.
