A thrilling, non-stop adventure packed with puzzles for the reader to solve.

  • Techniques, outils et astuces destinés aux formateurs, aux enseignants et aux animateurs de groupes.

  • Les scènes de crime peuvent contenir des centaines d'éléments de preuve. Les uns sont nets et aussi évidents qu'une empreinte de pas dans la neige ou le marteau utilisé pour casser une vitre. D'autres peuvent être quasi invisibles à l'oeil nu.
    Ce livre montre comment les spécialistes du CSI opèrent pour chercher et enregistrer des preuves sur les lieux d'un crime. -Ils peuvent photographier le site et faire des moules d'empreintes de pas ou de traces de pneus.
    Des empreintes digitales sont « relevées » et envoyées pour être comparées. Des échantillons minuscules de cheveux, de fibres, de verre et de sang sont tous collectés et enregistrés avec soin. Présentant plusieurs exemples et études de cas, Enquêtes CSI illustre comment ces enquêteurs spécialisés font leur travail, à la fois minutieux et essentiel.

  • Les criminels actuels peuvent n'avoir besoin que d'un ordinateur et d'une connexion Internet. Ils peuvent être des cybervandales causant beaucoup de dommages aux systèmes informatiques des entreprises ou des gouvernements, des cybervoleurs ou même des terroristes.
    Les experts judiciaires modernes doivent réagir en fouillant toutes sortes de données électroniques et d'informations numériques invisibles. Ils peuvent rechercher des pirates qui visent à perturber des réseaux informatiques, ou des criminels qui cherchent à s'enrichir en volant des informations ou l'identité d'autres personnes. Présentant de nombreux exemples et études de cas, Cybercrimes montre comment ces spécialistes font leur travail à la fois important et excitant.

  • Anglais The Islanders

    John Rowe Townsend

    The inhabitants of Halcyon Island are ruled by the laws of the Deliverer and follow the same customs and traditions that have prevailed for hundreds of years. The laws state 'No incomers', but when Thomas and Molly find a shipwrecked canoe with a boy and girl, barely alive, inside they are determined not to reject them outright. New blood on the island is bound to cause a disturbance, but the effects the incomers have on the close-knit community are beyond anyone's predictions.

  • Following the work of E. O. Wilson, Desmond Morris, and David Buss, What Women Want--What Men Want offers compelling new evidence about the real reasons behind men's and women's differing sexual psychologies and sheds new light on what men and women look for in a mate, the predicament of marriage in the modern world, the relation between sex and emotion, and many other hotly debated questions.
    Drawing upon 2000 questionnaires and 200 intimate interviews that show how our sexual psychologies affect everyday decisions, John Townsend argues against the prevailing ideologically correct belief that differences in sexual behavior are "culturally constructed." Townsend shows there are deep-seated desires inherited from our evolutionary past that guide our actions. In a fascinating series of experiments, men and women were asked to indicate preferences for potential mates based on their attractiveness and apparent economic status. Women overwhelmingly preferred expensively dressed men to more attractive but apparently less successful men, and men were clearly inclined to choose more attractive women regardless of their professional status. Townsend's studies also indicate that men are predisposed to value casual sex, whereas women cannot easily separate sexual relations from the need for emotional attachment and economic security. Indeed, wherever men possess sexual alternatives to marriage, and women possess economic alternatives, divorce rates will be high. In the concluding chapter, Townsend draws upon the advice of couples who have maintained their marriages over the years to suggest ways to survive our evolutionary predicament.
    Lucidly and accessibly written, What Women Want--What Men Want shows us why we are the way we are and brings new clarity to one of the most intractable debates of our time.

  • Begon, Townsend, and Harper's Ecology has long been regarded as the definitive textbook on all aspects of ecology. This new edition provides a comprehensive treatment of the subject, from the first principles of ecology to the current state of the field, and aims to improve students' preparedness to address the environmental problems of the new millennium.


    Thoroughly revised and updated, this fourth edition includes:


    three new chapters on applied ecology, reflecting a rigorous, scientific approach to the ecological problems now facing mankind

    discussion of over 800 new studies, updating the text throughout

    an updated, user-friendly design with margin notes and chapter summaries that serve as study aids

    dedicated website at www.blackwellpublishing.com/begon

    The resulting textbook is easy to use, lucid and up-to-date, and is the essential reference for all students whose degree program includes ecology and for practicing ecologists.

  • This Open Access volume aims to methodologically improve our understanding of biodiversity by linking disciplines that incorporate remote sensing, and uniting data and perspectives in the fields of biology, landscape ecology, and geography. The book provides a framework for how biodiversity can be detected and evaluated-focusing particularly on plants-using proximal and remotely sensed hyperspectral data and other tools such as LiDAR. The volume, whose chapters bring together a large cross-section of the biodiversity community engaged in these methods, attempts to establish a common language across disciplines for understanding and implementing remote sensing of biodiversity across scales.

    The first part of the book offers a potential basis for remote detection of biodiversity. An overview of the nature of biodiversity is described, along with ways for determining traits of plant biodiversity through spectral analyses across spatial scales and linking spectral data to the tree of life. The second part details what can be detected spectrally and remotely. Specific instrumentation and technologies are described, as well as the technical challenges of detection and data synthesis, collection and processing. The third part discusses spatial resolution and integration across scales and ends with a vision for developing a global biodiversity monitoring system. Topics include spectral and functional variation across habitats and biomes, biodiversity variables for global scale assessment, and the prospects and pitfalls in remote sensing of biodiversity at the global scale.
