This extract from Ovid's 'Theban History' recounts the confrontation of Pentheus, king of Thebes, with his divine cousin, Bacchus, the god of wine. Notwithstanding the warnings of the seer Tiresias and the cautionary tale of a character Acoetes (perhaps Bacchus in disguise), who tells of how the god once transformed a group of blasphemous sailors into dolphins, Pentheus refuses to acknowledge the divinity of Bacchus or allow his worship at Thebes. Enraged, yet curious to witness the orgiastic rites of the nascent cult, Pentheus conceals himself in a grove on Mt. Cithaeron near the locus of the ceremonies. But in the course of the rites he is spotted by the female participants who rush upon him in a delusional frenzy, his mother and sisters in the vanguard, and tear him limb from limb. The episode abounds in themes of abiding interest, not least the clash between the authoritarian personality of Pentheus, who embodies 'law and order', masculine prowess, and the martial ethos of his city, and Bacchus, a somewhat effeminate god of orgiastic excess, who revels in the delusional and the deceptive, the transgression of boundaries, and the blurring of gender distinctions. This course book offers a wide-ranging introduction, the original Latin text, study aids with vocabulary, and an extensive commentary. Designed to stretch and stimulate readers, Gildenhard and Zissos's incisive commentary will be of particular interest to students of Latin at AS and undergraduate level. It extends beyond detailed linguistic analysis to encourage critical engagement with Ovid's poetry and discussion of the most recent scholarly thought.

This is the first textbook on pattern recognition to present the Bayesian viewpoint. The book presents approximate inference algorithms that permit fast approximate answers in situations where exact answers are not feasible. It uses graphical models to describe probability distributions when no other books apply graphical models to machine learning. No previous knowledge of pattern recognition or machine learning concepts is assumed. Familiarity with multivariate calculus and basic linear algebra is required, and some experience in the use of probabilities would be helpful though not essential as the book includes a self-contained introduction to basic probability theory.

The functional properties of any molecule are directly related to, and affected by, its structure. This is especially true for DNA, the molecular that carries the code for all life on earth. The third edition of Understanding DNA has been entirely revised and updated, and expanded to cover new advances in our understanding. It explains, step by step, how DNA forms specific structures, the nature of these structures and how they fundamentally affect the biological processes of transcription and replication. Written in a clear, concise and lively fashion, Understanding DNA is essential reading for all molecular biology, biochemistry and genetics students, to newcomers to the field from other areas such as chemistry or physics, and even for seasoned researchers, who really want to understand DNA. Describes the basic units of DNA and how these form the double helix, and the various types of DNA double helix Outlines the methods used to study DNA structure Contains over 130 illustrations, some in full color, as well as exercises and further readings to stimulate student comprehension

Focusing on the concepts of biology, The World of Biology, Fifth Edition emphasizes the evolutionary and ecological relationships of the diverse organisms that inhabit our planet. The principal goals of this text are to provide students with the tools needed to function as biologically literate citizens and to develop in students an appreciation for science as evolving and dynamic. Engaging Chapter introductions, Concept Connections, and new Thinking Critically questions engage students in concepts of biology. A substantially revised Chapter 2 on the process of science encourages students to understand how scientists think. Major revision of genetics, ecology and botany units reflects current research.

In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequencies (Khush, 1973). Gene expression in the pollen might thus at least appear to be a phenomenon of trivial consequence. Indeed, Heslop-Harrison (1979) rightly termed the gametophytic portion of the angiosperm life cycle, the "forgotten generation." This neglect, however, came about despite subtle but constant indications that pollen is the site of intense gene activity and selection. For example, Mok and Peloquin (1975) demonstrated that relatively heterozygous diploid pollen shows heterotic characteristics whereas relatively homozygous diploid pOllen does not. This was proof positive that genes are expressed (that is, transcribed and translated) in the pollen. 1 Department of Botany, University of Massachusetts Amherst, MA 01003, USA viii However, the implications for pollen biology of even this recent and well known study were not widely recognized.
