The effect of image complexity on attentional bias towards alcohol-related images in adult drinkers

ADDICTION, Issue 5 2010
Melissa A. Miller
ABSTRACT Aim Visual probe tasks are often used to measure attentional bias (AB) towards alcohol-related images in drinkers, but little is known about the effect of the properties of the images used in this task: specifically, image complexity. Methods AB was examined in a group of adult drinkers (n = 25). Two measures of attentional bias were obtained from a modified visual probe task. First, a traditional dot probe detection task measured attentional bias in drinkers based on their reaction times to probes replacing neutral and alcohol-related images. Secondly, an eye-tracking measure was applied to this task to directly assess the drinkers' eye gazes to the alcohol-related and neutral images. The effect of image complexity was examined by comparing AB towards images classified as simple and complex. Findings Results showed that drinkers displayed AB only towards simple alcohol-related images as measured by both probe RT and fixation times. Conclusion These findings suggest that complex alcohol-related images might be less effective at capturing drinkers' attention and could result in less attentional bias when used in visual probe tasks.

Carbon Nanotubes: (Thermal and Structural Characterizations of Individual Single-, Double-, and Multi-Walled Carbon Nanotubes) Adv.

ADVANCED FUNCTIONAL MATERIALS, Issue 24 2009
Funct.
Here, M. T. Pettes and L. Shi report for the first time the thermal conductance, diameter, and chiral angle for a single single-walled carbon nanotube (SWCNT). A scanning electron micrograph of the suspended micro-thermometer device and transmission electron microscopy images used to determine the SWCNT's (22, 12) chirality are shown in this frontispiece image, along with the rendered unit cell.

Prospects for progress in diagnostic imaging

JOURNAL OF INTERNAL MEDICINE, Issue 4 2000

Abstract. Potchen EJ (Michigan State University, Michigan, USA). Prospects for progress in diagnostic imaging (Internal Medicine in the 21st Century). J Intern Med 2000; 247: 411,424. New fast-imaging MRI systems designed specifically for cardiac magnetic resonance enable new applications of noninvasive vascular imaging. The use of functional MRI and diffusion tensor imaging to map brain function and structure offers a new dimension to an understanding of the human condition. Clinical applications of functional MRI will influence many specialties including surgery, education, and rehabilitation. Functional imaging has the potential to visualize the regional concentration of specific proteins. This imaging at the level of molecules may be possible by use of a contrast material whose signal is changed by local enzymatic activity. The three-dimensional digital data collected in modern imaging techniques allow for virtual endoscopy in the respiratory, alimentary, and cardiovascular systems. Virtual endoscopy may replace many of the more invasive diagnostic methods in the near future. The measurement of clinical decision-making through observer performance studies better informs both the physician and the patient on how to improve upon the quality of clinical practice. These prospects for progress reinforce diagnostic imaging as a cornerstone in medical informatics. The history of creating images used in medicine reveals the invention of diagnostic tools which may provide new information but premature use can result in improper application of a poorly understood technology. Research into the use of new technology may be as important as the technology itself in improving the human condition. [source]

Library portal images that positively influence their users' perception of the portal

PROCEEDINGS OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE & TECHNOLOGY (ELECTRONIC), Issue 1 2008
James P. Smith
This paper provides an example of how visual information , the images used on academic library Web portals (ALWPs) , transforms users' perceptions of, and preference for, the portal. As a result of the information derived from this research the manner in which visual information is presented in ALWPs may be transformed. The study reported here compared the effect that high-image-pertinent (HIP) academic library portals and low-image-pertinent (LIP) academic library portals have on the users' preference for one portal over the other. One hundred undergraduate students searched for the answers to two ten-question information retrieval exercises using matched-pairs of HIP and LIP academic library portals. The exercises were constructed of questions similar to those asked at an academic library's reference desk. Data collected and statistically analyzed included: the scores from the information retrieval exercises, the time to complete the information retrieval exercises, the mouse-clicks used to complete the information retrieval exercises and the users' stated portal preference. The HIP portals outperformed the LIP portals and the subjects preferred the HIP portals to the LIP portals in 3 out of 4 measures of performance and preference. [source]

From sustainable management to sustainable development: a longitudinal analysis of a leading New Zealand environmental reporter

BUSINESS STRATEGY AND THE ENVIRONMENT, Issue 4 2006
Helen Tregidga
Abstract This paper reports the results of an interpretive textual analysis of New Zealand's most consistent and arguably leading reporter on environmental and social impacts. Since 1995, Watercare Services Ltd, an Auckland-based water utility, has been an award winning environmental reporter. The paper works with all of the organization's reports since 1993 through 2003 identifying and analysing the emergence and development of a sustainable development discourse. Focusing on the language and images used to construct meanings, and the context in which the reports emerged, the paper traces the organization's reporting developments. The paper illustrates how, in evolving from environmental reports to sustainable development reports, the organization has (re)constructed itself from one that sustainably manages resources to one that practises sustainable development. The implications of these developments are explored in terms of the literature on ,capture' and organizational change. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment. [source]
