As issues of employee involvement and participation once more evoke considerable controversy, this textbook provides an accessible overview of the main strands, perspectives and debates in current thinking and practice. It adopts a comparative international approach, addressing developments in the United Kingdom and mainland Europe, the United States and elsewhere. The authors identify two main strands of evolution: one driven by managerial interests in enhancing and controlling employee commitment and performance; the other deriving from employees' attempts to influence high-level organizational decision-making. In particular, they examine and analyze: the background of key concepts, issues and philosophies underpinning

Deals with the entire herpetofauna of Trinidad and Tobago, covering 130 species and subspecies and their natural history. Entries on species include information on description and distribution, and contain bandw distribution maps. Includes a section of general information describing the environments of the islands, plus some 170 color photos, and identification keys. For professional and amateur herpetologists, environmentalists, and ecotourists. Annotation copyright by Book News, Inc., Portland, OR.

Ticks of Trinidad and Tobago: An Overview explores tick species prevalent in Trinidad and Tobago (T&T), their distribution, associated pathogens, their effects on the host, and control methods. The book also reviews the basic biology of ticks. Ticks are known to parasitize a wide range of hosts including mammals, reptiles and birds. These parasites are of veterinary and public health significance since they are responsible for the spread of a number of pathogens to humans and animals. Worldwide, ticks are responsible for billions of dollars in losses in the livestock industry annually due to the effects of these pathogens. Based on review of the literature from more than five decades, twenty-three species of both hard and soft tick have been discovered on the twin-island republic with a greater number of species in Trinidad. Tick genera observed and recorded included Argas, Ornithodoros, Amblyomma, Dermacentor, Haemaphysalis, Ixodes, and Rhipicephalus species. The tick species found in Trinidad and Tobago parasitize both wild and domestic species. Hosts include bats, fowl, equids, wild and domestic ruminants, birds, rodents, marsupials, and a variety of reptiles such as toads, tortoises, and snakes. Based on geographical location, most tick species discovered in T&T have also been recorded in other Caribbean islands in the archipelago, North, Central and South America. Both soft and hard tick species found in T&T have also been implicated in a number of blood-borne pathogens including Borrelia, Ehrlichia, Babesia, Hepatozoon, Rickettsia, and Anaplasma. Examines the biology of tick species on hosts endemic to Trinidad and Tobago Provides pictorial keys Facilitates identification, prevention, and control of tick-borne diseases in the tropical region Assists with diagnosing tick-borne diseases

"Written for students at sixth form and undergraduate levels, and for 'the interested adult reader who might want to get a general feel for the subject', this is a systematic introduction to the rich diversity of Trinidad and Tobago's natural history, illustrated with maps and the author's own field photography. To manage a country's natural heritage effectively, the author argues, its organisms and ecosystems must be understood. Chronicling its degradation is not enough."--Publisher's description.

More than sixty species of snakes are found in the eastern United States, the region of highest biodiversity of all reptiles and amphibians in North America. In this brand new guide, stunning photographs, colorful geographic range maps, and comprehensive written accounts provide essential information about each species—including detailed identification characteristics, general ecology and behavior, and conservation status. Carefully researched and written by an expert herpetologist, the guide is directed toward a general audience interested in natural history. Additional information supports the already fact-filled snake species profiles. A chapter on urban and suburban snake ecology focuses on species most commonly found in some of the country’s largest cities and residential settings. A chapter on snake conservation includes information on threats faced by native species in many regions of the eastern United States. Another chapter provides the latest updates on the status of invasive species of pythons and boa constrictors that have now become naturalized permanent residents in certain areas of the country. This is the most accessible and informative guide to snakes of the eastern United States available anywhere. Covers snakes in these states (plus Washington, DC): Alabama, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, West Virginia, and Wisconsin. Features: More than 385 stunning color photographsColorful geographic range mapsSpecies accounts that cover identification, general ecology and behavior, and conservation statusExtra information on snakes in urban and suburban areasStrong conservation message, with a focus on environmental threats to native speciesCoverage of invasive snakes
