Download or read book Foraging Theory Applied to Medical Information Searching written by Mai Dwairy and published by Xlibris Corporation. This book was released on 2012-10 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Workload and other constraints prevent General Practitioners from accessing medical evidence for clinical decisions. This problem was studied in New Zealand GPs using Optimal Foraging Theory developed in ecology. GPs' information search strategies were modelled as sequential steps associated with costs and benefits measured from logbooks of actual searches. By consulting the most profitable sources, switching sources when unsuccessful, and double checking, GPs seem close to an optimal trade-off between maximizing search success and information reliability, and minimizing searching time. Subsidised training in information searching and provision of a literature search service are two inferred avenues to access medical evidence.

Download or read book Foraging written by David W. Stephens and published by University of Chicago Press. This book was released on 2008-09-15 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to succeed, and they make extraordinary efforts to do so. For instance, pythons rarely eat, but when they do, their meals are large—as much as 60 percent larger than their own bodies. The snake’s digestive system is normally dormant, but during digestion metabolic rates can increase fortyfold. A python digesting quietly on the forest floor has the metabolic rate of thoroughbred in a dead heat. This and related foraging processes have broad applications in ecology, cognitive science, anthropology, and conservation biology—and they can be further extrapolated in economics, neurobiology, and computer science. Foraging is the first comprehensive review of the topic in more than twenty years. A monumental undertaking, this volume brings together twenty-two experts from throughout the field to offer the latest on the mechanics of foraging, modern foraging theory, and foraging ecology. The fourteen essays cover all the relevant issues, including cognition, individual behavior, caching behavior, parental behavior, antipredator behavior, social behavior, population and community ecology, herbivory, and conservation. Considering a wide range of taxa, from birds to mammals to amphibians, Foraging will be the definitive guide to the field.

Download or read book Mathematical Ecology written by Thomas G. Hallam and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: There isprobably no more appropriate location to hold a course on mathematical ecology than Italy, the countryofVito Volterra, a founding father ofthe subject. The Trieste 1982Autumn Course on Mathematical Ecology consisted of four weeksofvery concentrated scholasticism and aestheticism. The first weeks were devoted to fundamentals and principles ofmathematicalecology. A nucleusofthe material from the lectures presented during this period constitutes this book. The final week and a half of the Course was apportioned to the Trieste Research Conference on Mathematical Ecology whose proceedings have been published as Volume 54, Lecture Notes in Biomathematics, Springer-Verlag. The objectivesofthe first portionofthe course wereambitious and, probably, unattainable. Basic principles of the areas of physiological, population, com munitY, and ecosystem ecology that have solid ecological and mathematical foundations were to be presented. Classical terminology was to be introduced, important fundamental topics were to be developed, some past and some current problems of interest were to be presented, and directions for possible research were to be provided. Due to time constraints, the coverage could not be encyclopedic;many areas covered already have merited treatises of book length. Consequently, preliminary foundation material was covered in some detail, but subject overviewsand area syntheseswerepresented when research frontiers were being discussed. These lecture notes reflect this course philosophy.

This book was released on 2013-06-29 with total page 887 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioural Mechanisms of Food Selection examines animals belonging to diverse trophic groups, from carnivores, herbivores, micro-algal grazers, to filter-feeders and detritus-feeders. In the past Optimal Foraging Theory has been applied to all these groups, but in different ways and in disci plines that rarely overlap. Here concepts and developments hitherto scattered in the literature are drawn together. This uniquely broad synthesis captures the state of the art in the study of diet selection and prescribes new objectives in theoretical development and research.
Download or read book Exploratory Search written by Ryen White and published by Springer Nature. This book was released on 2022-06-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: As information becomes more ubiquitous and the demands that searchers have on search systems grow, there is a need to support search behaviors beyond simple lookup. Information seeking is the process or activity of attempting to obtain information in both human and technological contexts. Exploratory search describes an information-seeking problem context that is open-ended, persistent, and multifaceted, and information-seeking processes that are opportunistic, iterative, and multitactical. Exploratory searchers aim to solve complex problems and develop enhanced mental capacities. Exploratory search systems support this through symbiotic human-machine relationships that provide guidance in exploring unfamiliar information landscapes. Exploratory search has gained prominence in recent years. There is an increased interest from the information retrieval, information science, and human-computer interaction communities in moving beyond the traditional turn-taking interaction model supported by major Web search engines, and toward support for human intelligence amplification and information use. In this lecture, we introduce exploratory search, relate it to relevant extant research, outline the features of exploratory search systems, discuss the evaluation of these systems, and suggest some future directions for supporting exploratory search. Exploratory search is a new frontier in the search domain and is becoming increasingly important in shaping our future world.

Download or read book Systematic Searching written by Paul Levay and published by Facet Publishing. This book was released on 2019-01-15 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: In resource poor, cost saving times, this book provides practical advice on new methods and technologies involved in systematic searching and explores the role of information professionals in delivering these changes The editors bring together expert international practitioners and researchers to highlight the latest thinking on systematic searching. Beginning by looking at the methods and techniques underlying systematic searching, the book then examines the current challenges and the potential solutions to more effective searching in detail, before considering the role of the information specialist as an expert searcher. Systematic Searching blends theory and practice and takes into account different approaches to information retrieval with a special focus being given to searching for complex topics in a health-related environment. The book does not presume an in-depth prior knowledge or experience of systematic searching and includes case studies, practical examples and ideas for further research and reading. The book is divided into three parts: Methods covers theoretical approaches to evidence synthesis and the implications that these have for the search process, including searching for complex topics and choosing the right sources. Technology examines new technologies for retrieving evidence and how these are leading to new directions in information retrieval and evidence synthesis. People considers the future of the information specialist as an expert searcher and explores how information professionals can develop their skills in searching, communication and collaboration to ensure that information retrieval practice is, and remains, evidence-based. Systematic Searching will be essential reading for library and information service providers and information specialists, particularly those in a health-related environment. It will also be of interest to students of library and information science, systematic reviewers, researchers and practitioners conducting complex searches in settings including social care, education and criminal justice.
Download or read book Hidden Markov Models for Time Series written by Walter Zucchini and published by CRC Press. This book was released on 2017-12-19 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hidden Markov Models for Time Series: An Introduction Using R, Second Edition illustrates the great flexibility of hidden Markov models (HMMs) as general-purpose models for time series data. The book provides a broad understanding of the models and their uses. After presenting the basic model formulation, the book covers estimation, forecasting, decoding, prediction, model selection, and Bayesian inference for HMMs. Through examples and applications, the authors describe how to extend and generalize the basic model so that it can be applied in a rich variety of situations. The book demonstrates how HMMs can be applied to a wide range of types of time series: continuous-valued, circular, multivariate, binary, bounded and unbounded counts, and categorical observations. It also discusses how to employ the freely available computing environment R to carry out the computations. Features Presents an accessible overview of HMMs Explores a variety of applications in ecology, finance, epidemiology, climatology, and sociology Includes numerous theoretical and programming exercises Provides most of the analysed data sets online New to the second edition A total of five chapters on extensions, including HMMs for longitudinal data, hidden semi-Markov models and models with continuous-valued state process New case studies on animal movement, rainfall occurrence and capture-recapture data
