The Cognitive Dimensions framework outlined here is generalised broad-brush approach to usability evaluation for all types of information artifact, from programming languages through interactive systems to domestic devices. It also has promise of interfacing successfully with organisational and sociological analyses.
This tutorial, originally prepared for the BCS HCI Conference of 1998, will provide a concise introduction to Green's "Cognitive Dimensions", with illustrative practical applications. The Cognitive Dimensions Framework is one of the few theoretical approaches that provides a practical usability tool for everyday analysts and designers. It is unique in… (More)
In this paper we propose to decompose the traditional constraint of Foot Binarity (a metrical foot is either bimoraic or disyllabic, Hayes 1985, McCarthy & Prince 1986) into two constraints: Min-2, which sets a lower bound on foot size requiring it to be at least two moras or two syllables, and Lapse (Green 1995). (1) Ft-Binarity: a metrical foot is either… (More)
Drugs of abuse cause activation of the cyclic AMP response element binding protein (CREB) in the nucleus accumbens (NAc). Expression of active CREB in rat NAc medium spiny neurons (MSNs) increased their excitability, whereas dominant-negative CREB had the opposite effect. Decreasing excitability of NAc MSNs in vivo by overexpression of potassium channels… (More)
Rats raised in an enriched condition (EC) during development display increased hyperactivity to the effect of acute amphetamine compared to rats raised in an impoverished condition (IC). The present study determined whether environmental enrichment differentially alters the effects of GBR 12935 administration, a selective dopamine transporter (DAT)… (More)
The Department of Anthropology offers programs of study and research leading to the MA and PhD in anthropology. Additionally, a focus in Maritime Archaeology and Conservation is offered as an MS. Students enrolled within these programs receive training preparing them for professional research and/or teaching careers in academic institutions, governmental… (More)
Production of mRNA from the cocaine- and amphetamine-regulated transcript (CART) gene is regulated by cocaine and other drugs of abuse in the nucleus accumbens (NAc), a brain reward region. Current hypotheses postulate that CART peptides there oppose the rewarding actions of cocaine by opposing the effects of dopaminergic transmission. Since over expression… (More)
