We are pleased to present the proceedings of the 5th Workshop on Algorithms in Bioinformatics (WABI 2005) which took place in Mallorca, Spain, October 3-6, 2005. The WABI 2005 workshop was part of the ?ve ALGO 2005 conf- ence meetings, which, in addition to WABI, included ESA, WAOA, IWPEC, and ATMOS. WABI 2005 was sponsored by EATCS (the European Assoc- tion for Theoretical Computer Science), the ISCB (the International Society for Computational Biology), the Universitat Polit ecnica de Catalunya, the U- versitat de les Illes Balears, and the Ministerio de Educaci on y Ciencia. See http: //www.lsi.upc.edu/ wabi05/ for more details. The Workshop on Algorithms in Bioinformatics highlights research work speci?cally developed to address algorithmic problems in biosequence analysis. Theemphasisisthereforeonstatisticalandprobabilisticalgorithmsthataddress important problems in the ?eld of molecular and structural biology. At present, given the enormous scienti?c and technical e?orts in functional and structural genomics, the relevance of the problem is therefore constrained by the need for sound, e?cient and specialized algorithms, capable of achieving solutions that can be tested by the biological community. Indeed the ultimate goal is to - plement algorithms capable of extracting real features from real biological data sets. Therefore the workshop aims to present recent research results, including signi?cant work in progress, and to identify and explore directions of future research."

What role does an animal play in a child's developing sense of self? Are children and animals interacting in ways no longer recognizable to adults? The Significance of Children and Animals addresses these and other intriguing questions by revealing the interconnected lives of the inhabitants of the preschool classroom - an environment abounding in childish verbal and nonverbal interactions with birds, turtles, toads, birds, bugs, and other creatures. Regarded as a pivotal analysis of child-animal interaction with wider implications for human-animal studies, the original 1998 edition has been revised here to incorporate the recent literature, while preserving the basic nature of the text. This book provides a delightful and rewarding opportunity for parents, educators, and students of early childhood social development, as well as scholars of the intersection of human experience and the natural environment.
