The multitrophic level approach to ecology addresses the complexity of food webs much more realistically than the traditional focus on simple systems and interactions. Only in the last few decades have ecologists become interested in the nature of more complex systems including tritrophic interactions between plants, herbivores and natural enemies. Plants may directly influence the behaviour of their herbivores' natural enemies, ecological interactions between two species are often indirectly mediated by a third species, landscape structure directly affects local tritrophic interactions and below-ground food webs are vital to above-ground organisms. The relative importance of top-down effects (control by predators) and bottom-up effects (control by resources) must also be determined. These interactions are explored in this exciting volume by expert researchers from a variety of ecological fields. This book provides a much-needed synthesis of multitrophic level interactions and serves as a guide for future research for ecologists of all descriptions

Les gestes relationnels diffèrent selon les contextes dans lesquels ils ont été incorporés. Cette incorporation n'est pas simplement de l'ordre de l'imitation, mais imprègne tout à la fois le ressenti, la conscience corporelle et l'identité, ainsi que le sens et les valeurs, dans un système complexe. Ces travaux dégagent trois niveaux de cohérence. Une cohérence interne relie les comportements aux intentions et aux valeurs de la personne. Une cohérence interpersonnelle se co-construit dans l'instant de l'échange. Enfin, une cohérence externe relie l'individu et ses milieux d'appartenance. La rencontre de systèmes culturels différents des siens provoque la redécouverte des liens de sens et la prise de conscience de ces différents niveaux écologiques.

Volume 37 in the bi-annual series Studies in Symbolic Interaction is divided into three distinct parts: Part One, Theoretical Openings, focuses on new theoretical work in the interactionist tradition by leading interdisciplinary scholars. It examines the mesodomain of welfare reform through re-negotiating the order of economic inequality, provides a grounded fractal analysis into the medicalization of homelessness and the sociology of the self, and looks at the labeling of immigrant men as criminals. In Part Two, Studies in Social Construction, focus shifts to issues of gender, ethnicity, illness and the urban situation including articles on the social constructions of the non-prejudiced white self, womens interaction with romantic comedies and the impact on their relationship, and engaging cultural narratives of the ethnic restaurant. The third and final part, Autoethnographic Interventions, turns inward to autoethnographic reflections on identity, technology, family, work and self including contributions on the digital evolution of an American identity and nursings moral imperative as the flexible professional and the discourse of unexpected evidence.

Volume 27 of "Studies in Symbolic Interaction" emphasizes new developments in interactional theory and practice, as well as examples of post-modern ethnography and performance texts focused on border crossings and border performances. The volume also presents essays honoring Laurel Richardsons contributions to Symbolic Interaction and Communications, as well as the inaugural address in the "Peter M. Hall Lecture Series".

This volume emphasizes interpretive interactionist work on race, media, culture and identity. Experimental, autoethnographic performance texts are privileged, as are recent theoretical developments in symbolic interaction theory involving critical humanism, pragmatic theories of power and the layered bureaucracy. It also presents essays on the New Iowa School, the work of Gideon. S. Joberg, cultural studies and symbolic interactionism, including the work of Norman Denzin.
