This book discusses innovative methods for mining information from images of plants, especially leaves, and highlights the diagnostic features that can be implemented in fully automatic systems for identifying plant species. Adopting a multidisciplinary approach, it explores the problem of plant species identification, covering both the concepts of taxonomy and morphology. It then provides an overview of morphometrics, including the historical background and the main steps in the morphometric analysis of leaves together with a number of applications. The core of the book focuses on novel diagnostic methods for plant species identification developed from a computer scientist's perspective. It then concludes with a chapter on the characterization of botanists' visions, which highlights important cognitive aspects that can be implemented in a computer system to more accurately replicate the human expert's fixation process. The book not only represents an authoritative guide to advanced computational tools for plant identification, but provides experts in botany, computer science and pattern recognition with new ideas and challenges. As such it is expected to foster both closer collaborations and further technological developments in the emerging field of automatic plant identification.

Person-centred therapy, rooted in the experience and ideas of the eminent psychotherapist Carl Rogers, is widely practised in the UK and throughout the world. It has applications in health and social care, the voluntary sector and is relevant to work with people who are severely mentally and emotionally distressed. As well as being a valuable sourcebook and offering a comprehensive overview, this edition includes updated references and a new section on recent developments and advances. The book begins with a consideration of the principles and philosophy underpinning person-centred therapy before moving to a comprehensive discussion of the classical theory upon which practice is based. Further areas of discussion include: The model of the person, including the origins of mental and emotional distress The process of constructive change A review of revisions of and additions to person-centred theory Child development, styles of processing and configurations of self The quality of presence and working at relational depth Criticisms of the approach are addressed and rebutted and the application of theory to practice is discussed. The new final section is concerned with advances and developments in theory and practice including: Counselling for Depression The Social Dimension to Person-Centred Therapy Person-Centred Practice with People experiencing Severe and Enduring Distress and at the 'Difficult Edge' A Review of Research Throughout the book, attention is drawn to the wider person-centred literature to which it is a valuable key. Person-Centred Therapy will be of particular use to students, scholars and practitioners of person-centred therapy as well as to anyone who wants to know more about one of the major psychotherapeutic modalities.

This fascinating book introduces the rationale, theory and psychotherapeutic practice of psychodrama. It provides an insight into its origins, outlining its techniques and bringing to life the dynamic interrelationships that form the core of the practice. Following the theatrical process that lies at the heart of psychodrama, the book shows how the enactment of scenes from the past, present or future, real or imagined, can benefit the group of individuals involved, leading to unexpected insight and growth through creativity and spontaneity. Psychodramatic terms and processes are explained and illustrated using numerous examples from practice.

It is widely acknowledged that research is an essential component of the counselling and psychotherapy core curriculum. Therapists and all care practitioners not only need to be able to understand and evaluate research literature, but are also increasingly expected to carry out simple practitioner research to monitor their own practice. With its emphasis on practice-based evidence, this book provides a much-needed, reliable and accessible introduction by two trusted and well-known authors. It builds confidence by not only outlining contemporary methodologies in everyday language, but also by explaining how to approach, understand and evaluate a range of published research. Written for complete beginners in the tried and tested, best-selling style of the other books in the "Steps" series, the book covers first principles through to the development of a simple research project. In simple terms "First Steps in Practitioner Research" provides a 'how to understand and do it' resource for students, tutors and practice supervisors with little or no previous experience.

This is the first book to focus on commonly occurring client issues and explore how to work with them from a person-centred perspective. Extensive case studies translate person-centred theory into effective practice, enabling therapists to work successfully with clients presenting a variety of different problems including: - Post Traumatic Stress - Depression - Panic and Anxiety - Drug and Alcohol Issues - Eating difficulties - Self harm - Childhood Sexual Abuse Each chapter covers the origin and meaning of the difficulty, the person-centred therapeutic approach and process, and the outcomes. Drawing from a combined 50 years of experience in the field, Paul Wilkins and Janet Tolan bring together leading person-centred therapists to address how and why each problem can be eased by means of working with the person. This book should be on the desk of every counselling and psychotherapy trainee, and is recommended reading for other practitioners of health and social care working with these client groups.

Tracing the evolution of one of the most ancient major branches of flowering plants, this is a wide-ranging survey of state-of-the-art research on the early clades of the monocot phylogenetic tree. It explores a series of broad but linked themes, providing for the first time a detailed and coherent view of the taxa of the early monocot lineages, how they diversified and their importance in monocots as a whole. Featuring contributions from leaders in the field, the chapters trace the evolution of the monocots from largely aquatic ancestors. Topics covered include the rapidly advancing field of monocot fossils, aquatic adaptations in pollen and anther structure and pollination strategies and floral developmental morphology. The book also presents a new plastid sequence analysis of early monocots and a review of monocot phylogeny as a whole, placing in an evolutionary context a plant group of major ecological, economic and horticultural importance.

Dioscoreales are a small but systematically and economically significant order of monocotyledons. The most diverse and important member is the yam genus, Dioscorea L., a source of dietary starch at macroeconomic to rural community levels. Other species of Dioscorea provided the chemical basis of corticosteroid drugs and oral contraceptives. Ally families comprise the unusual, largely achlorophyllous (heteromycotrophic) Burmanniaceae and the relatively unspecialised Nartheciaceae. The World Checklist of Dioscoreales lists all validly published names of yams and their allies, providing the source of their publication and indication of which names are currently accepted and which are synonyms, making it a standard nomenclatural reference for further research into this important family. The World Checklist of Dioscoreales: .Lists all names ever published .Lists all accepted species with their geographical distribution .Indicates full synonymy .Provides a single source guide to the correct names of all yams and their allies .Provides an invaluable reference for applied yam researchers, e.g. pathologists, geneticists, plant breeders, conservationists, foresters, ethnobotanists, ethnoarchaeologists and anthropologists

Person-Centred Therapy in Focus provides a much-needed exploration of the criticisms levelled against one of the most widespread forms of therapeutic practice. Characterized by its critics as theoretically `light', culturally biased and limited in application, until now the person-centred approach has had comparatively little written in its defence.

Paul Wilkins provides a rigorous and systematic response to the critics, drawing not only on the work of Carl Rogers, but also of those central to more recent developments in theory and practice (including Goff Barrett-Lennard, Dave Mearns, Jerold Bozarth, Germain Leitauer and Brian Thorne). It traces the epistemological foundations of person-centred therapy and places the approach in its social and political context.

Examining the central tenets of the approach, each chapter sets out concisely the criticisms and then counters these with arguments from the person-centred perspective. Chapters cover debates in relation to:

- the model of the person

- self-actualization

- the core conditions

- non-directivity

- resistance to psychopathology

- reflection, and

- boundary issues.

Person-Centred Therapy in Focus fulfills two important purposes: firstly to answer the criticisms of those who have attacked the person-centred approach and secondly to cultivate a greater critical awareness and understanding within the approach itself. As such it makes a significant contribution to the person-centred literature and provides an excellent resource for use in training.

In this title, another distinguished international collection of theorists and practitioners lead the serious student to a cutting-edge appreciation of Unconditional Positive Regard. Once dubbed a 'controversial' condition by Germain Lietaer, and seen by Jerold Bozarth as the 'curative factor' in client-centred therapy, UPR has never before had so much attention focused on it. Readers from all disciplines can discover how contemporary person-centred therapists are thinking about, and working with, this 'core' condition.

`The book is helpfully structured with its cental chapters broadly following the shape of a typical psychodrama session' - Journal of Critical Psychology, Counselling & Psychology `As with all Paul Wilkins writings the book is thorough and well-researched, with a wealth of information arising from wide readership and personal communication.... My own view is that the book fulfils its aim as an introduction to psychodrama for the audience it addresses. It also is packed with information about areas which experienced psychodramatists and sociodramatists will wish to debate' - British Psychodrama Association Journal The text unfolds in such a way that the central feature of psychodrama as an action therapy is spontaneously made manifest. The book is good for students of this method and would be a challenging refresher for practitioners in the field. All the special terms used by psychodramatists are defined in a succinct glossary so that the uninitiated will not be bewildered on first encountering "auxilliary egos", "surplus reality", "social atoms" or even the titillating idea of "act hunger"!
