Constructing Languages


Book Description

As language historians we believe that the subject of our study is neither natural languages nor idiolects which speakers have always been able to develop individually (loosely what Chomsky calls L-i), but rather the social constructions of reference shared by all speakers (basically what Chomsky terms as L-e ). In this context the language historian essentially studies how a public L-e is built such that it can be understood as the language of all (i.e. hiding L-i variations) and also how L-e succeed in replacing the primary reality of idiolects, even if only in the imagination. Writing represents a crucial turning point in language construction, because it made it possible to materialize the abstraction that, until then, related speakers could only guess and besides it comes into competition with individual languages. In modern centuries, the provision of grammars, dictionaries and other such learning tools and systematizing instruments strengthens the idea that, because of their normative character, languages can be learned through study. Mythical stories encourage the achievement of prescriptive rules and lead speakers to link emotions to their language. Therefore, the topics of reflection that we want to discuss in this volume are: Norms, Myths and Emotions related to language construction.




El descrèdit de la modernitat


Book Description

A pesar d?haver estat qüestionada per una gran part del pensament contemporani, la modernitat encara continua vigent com a actitud crítica i de reflexió sobre el present. L?autora analitza aquest «debat inacabat» al voltant de la modernitat cultural, la modernització social, la crítica del temps històric i la construcció i fragmentació del subjecte.




The Handbook of Mites of Economic Plants


Book Description

Mites pose a serious problem to plants worldwide, attacking crops and spreading disease. When mites damage crops of economic importance the impacts can be felt globally. Mites are among the most diverse and successful of invertebrates, with over 45,000 described species, with many more thousands to be discovered. They are responsible for a significant portion of the losses of crops for food, fibre, industry and other purposes, and require expensive and often controversial pest control measures. Understanding these mites is vital for entomologists, pest researchers, agronomists and food producers. Knowledge of mite pests helps to inform control strategies and optimize the production of economic plants and the agrarian economy. This encyclopedia provides a thorough coverage of the mites and the problems they cause to crops, yet it is easily searchable, organised by mite species and subdivided into helpful headings. It takes a worldwide view of the issue of mites injurious to economic plants, describing mites prevalent in different regions and discussing control methods appropriate in different environments. This book provides an encyclopaedic reference to the major mites, described by family in terms of their internal and external morphology, bio-ecology and family systematics. Methods of mite collection and laboratory study is described, as well as species diagnostic characteristics, worldwide distribution, host plants, identification by the type of damage they cause and control strategies, including chemical and biological intervention and integrated pest management measures. Mites of the following families are included: (Eriophyoidea, Tarsonemidae, Tuckerellidae, Tenuipalpidae, Tetranychidae, Acaridae, Penthaleidae). Mites of Economic Plants is an important resource for students of entomology and crop production, and as a thorough reference guide for researchers and field workers involved with mites, crop damage and food production.







Biology


Book Description

For one or two semester courses in Introductory Biology targeting non- and mixed majors. The goal of this text is to provide an engaging and easy to use book with an innovative and interactive media program. It achieves a unique balance in emphasizing concepts without sacrificing scientific accuracy. The new MediaTutor, found at the end of each chapter, integrates the text and media by providing a brief description of the CD or WEB activity and the time requirement for completion. In creating the book and the media package, the authors and Prentice Hall reached out to the biology community - involving educators from around the country to help address the diverse needs of todays students. How do you engage your students and help make biology relevant to them? *NEW - Chapter-opening Case Studies and chapter-ending Case Studies Revisited - Includes Did Dinosaurs Die from Lack of Sunlight? from the chapter on Photosynthesis and Teaching an Old Grain New Tricks from the chapter on Biotechnology. Provides an innovative framework for students to learn and make connections between biological concepts and processes. *Earth Watch/Health Watch essays - Covers biodiversity, ozone depletion/pre




Citrus Mites


Book Description

Citrus pests are a serious issue for crop growers, causing problems in yield and economic losses. This title studies mites harmful to citrus plants from various citrus growing regions around the world. It addresses methods of removal from plants, describes symptoms of damage caused by pests and discusses methods of eradication and control.




Another Country


Book Description

This book studies the emergence, in the late 1960s and 1970s, of a sophisticated body of gay fiction in Catalan, and examines the relation between the representation of homosexuality and the discourses on national identity that legitimate modern Catalan literature. Gay fiction, argues the author, reveals a tension between the nation and the body in Catalan literature: Catalonia is a nation different from Spain, a cultural and political minority within Europe; but the existence of sexual minorities within its boundaries reveals its inner complexity, which resists homogenization. Catalonia is another country in more ways than one. Drawing on a variety of critical discourses (gay theory, psychoanalysis, and authors such as Foucault, Deleuze and Guattari, and Bourdieu), Another Country explores the intertwinings of identity, cultural politics, and desire in the work of Terenci Moix, Lluis Fernandez, Biel Mesquida, and Lluis Maria Todo. The book analyses how gay writers renegotiate identity discourses in Catalan literature in order to introduce homosexuality into them, often with destabilising effects. The role of gay authors in the process of canon construction (a crucial aspect of contemporary cultural nationalism in Catalonia) is also considered, focusing on postmodernism and the divide between high and mass culture. Finally, Another Country addresses the interplay of homosexual desire within the frame of a distinction between perversion and transgression, and proposes an alliance between queer and nationalist discourses.

Prospects for Biological Control of Plant Feeding Mites and Other Harmful Organisms


Book Description

The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.
