Educating Clients with speech and language impairments

Speech and language impairments can result in communication disabilities that can affect clients' capacity to read, write and participate in conversations and social situations.

Linking policies for biodiversity conservation with advances in behavioural economics

Global biodiversity loss and its consequences for human welfare and sustainable development have become major concerns. Economists have, therefore, given increasing attention to the policy issues involved in the management of genetic resources. To do so, they often apply empirical methods developed in behavioral and experimental economics to estimate economic values placed on genetic resources. This trend away from almost exclusive dependence on axiomatic methods is welcomed. However, major valuation methods used in behavioral economics raise new scientific challenges. Possibly the most important of these include deficiencies in the knowledge of the public (and researchers) about genetic resources, implications for the formation of values of supplying information to focal individuals, and limits to rationality. These issues are explored for stated-preference techniques of valuation (e.g., contingent valuation) as well as revealed preference techniques, especially the travel cost method. They are illustrated by Australian and Asian examples. Taking into account behavioral and psychological models and empirical evidence, particular attention is given to how elicitation of preferences, and supply of information to individuals, influences their preferences about biodiversity. Policy consequences are outlined.

Language and disability in Japan

Language relating to disability in the public arena has been a sensitive issue in Japan as elsewhere. Since the 1970s and 80s, major media organisations have replaced words considered derogatory with more acceptable equivalents; laws, statutes and other legal documents have likewise been revised. This article examines how the language used to portray people with disabilities has changed, how the changes came about and how they were received. The debate has largely been played out in four public spaces, which to some extent intersect and overlap: the media (both print and visual), the laws, literature and, increasingly now, the Internet. I argue that while the laws were rewritten primarily as the result of external international trends, such as the International Year of Disabled Persons, disability groups achieved media compliance mainly by exploiting the keen desire of Japanese media organisations to avoid public embarrassment resulting from vocal protests over infractions.

MapScript: A map algebra programming language incorporating neighborhood analysis

Map algebra is a data model and simple functional notation to study the distribution and patterns of spatial phenomena. It uses a uniform representation of space as discrete grids, which are organized into layers. This paper discusses extensions to map algebra to handle neighborhood operations with a new data type called a template. Templates provide general windowing operations on grids to enable spatial models for cellular automata, mathematical morphology, and local spatial statistics. A programming language for map algebra that incorporates templates and special processing constructs is described. The programming language is called MapScript. Example program scripts are presented to perform diverse and interesting neighborhood analysis for descriptive, model-based and processed-based analysis.
