problems in addition to the signs of the Wernicke-Korsakoff syndrome. Many of the patients were closely examined over long periods and the authors make the point that repeated examinations for as long as ten years in some instances allowed them to describe the natural history of the syndrome. and this they do in their third chapter. Again the description of the pathological findings is precise and comprehensive and the authors stress the periventricular distribution of the lesions and their bilateral symmetry. The authors consider specifically the neuropathological substrate on which are based the defective memory, ocular motor signs, the ataxia, the global confusional state and the occasional disturbance of olfactory and gustatory function. They argue a unity between Wernicke's disease and Korsakoff's psychosis and discuss the relationship between these two and alcoholic cerebellar degeneration, central pontine myelinolysis and other myelinolytic syndromes and interestingly discuss the problem of \"alcoholic dementia\" concluding that the nosological status ofalcoholic dementia is by

The successful adoption of technology is becoming increasingly important to functional independence. The present article reports findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) on the use of technology among communitydwelling adults. The sample included 1,204 individuals ranging in age from 18–91 years. All participants completed a battery that included measures of demographic characteristics, self-rated health, experience with technology, attitudes toward computers, and component cognitive abilities. Findings indicate that the older adults were less likely than younger adults to use technology in general, computers, and the World Wide Web. The results also indicate that computer anxiety, fluid intelligence, and crystallized intelligence were important predictors of the use of technology. The relationship between age and adoption of technology was mediated by cognitive abilities, computer self-efficacy, and computer anxiety. These findings are discussed in terms of training strategies to promote technology adoption.

Factors Predicting the Use of Technology: Findings From the Center for Research and Education on Aging and Technology Enhancement (CREATE)

The Protective Action Decision Model (PADM) is a multistage model that is based on findings from research on people's responses to environmental hazards and disasters. The PADM integrates the processing of information derived from social and environmental cues with messages that social sources transmit through communication channels to those at risk. The PADM identifies three critical predecision processes (reception, attention, and comprehension of warnings or exposure, attention, and interpretation of environmental/social cues)--that precede all further processing. The revised model identifies three core perceptions--threat perceptions, protective action perceptions, and stakeholder perceptions--that form the basis for decisions about how to respond to an imminent or long-term threat. The outcome of the protective action decision-making process, together with situational facilitators and impediments, produces a behavioral response. In addition to describing the revised model and the research on which it is based, this article describes three applications (development of risk communication programs, evacuation modeling, and adoption of long-term hazard adjustments) and identifies some of the research needed to address unresolved issues.

The Protective Action Decision Model: Theoretical Modifications and Additional Evidence

During the past four decades (1960–2000), the United States experienced major transformations in population size, development patterns, economic conditions, and social characteristics. These social, economic, and built-environment changes altered the American hazardscape in profound ways, with more people living in high-hazard areas than ever before. To improve emergency management, it is important to recognize the variability in the vulnerable populations exposed to hazards and to develop place-based emergency plans accordingly. The concept of social vulnerability identifies sensitive populations that may be less likely to respond to, cope with, and recover from a natural disaster. Social vulnerability is complex and dynamic, changing over space and through time. This paper presents empirical evidence on the spatial and temporal patterns in social vulnerability in the United States from 1960 to the present. Using counties as our study unit, we found that those components that consistently increased social vulnerability for all time periods were density (urban), race/ethnicity, and socioeconomic status. The spatial patterning of social vulnerability, although initially concentrated in certain geographic regions, has become more dispersed over time. The national trend shows a steady reduction in social vulnerability, but there is considerable regional variability, with many counties increasing in social vulnerability during the past five decades.

Prospective memory situations involve forming intentions and then realizing those intentions at some appropriate time in the future. An interesting feature of most prospective remembering is that recollection of the intended action occurs without an explicit request to attempt retrieval, and we present two views on how this type of remembering can be accomplished. One could strategically monitor the environment for the presence of the target event, or one could rely on anticipated environmental conditions more or less automatically reinstating the intended action. We present data supporting both views and argue that people use multiple approaches for solving the problem of retrieving an intention (prospective memory) after a delay. Moreover, we suggest that the extent to which prospective remembering is supported by relatively automatic processes (versus strategic resource-demanding monitoring) and the probability with which prospective memory is likely to be successful when relying on automatic processes varies as a function of the characteristics of the prospective memory task, target cue, ongoing task, and individual. We argue that the complexity of the empirical findings can best be understood by appealing to this multiprocess view of prospective memory. Copyright © 2000 John Wiley & Sons, Ltd.

Strategic and automatic processes in prospective memory retrieval: a multiprocess framework

Security tools could help developers find critical vulnerabilities, yet such tools remain underused. We surveyed developers from 14 companies and 5 mailing lists about their reasons for using and not using security tools. The resulting thirty-nine predictors of security tool use provide both expected and unexpected insights. As we expected, developers who perceive security to be important are more likely to use security tools than those who do not. But that was not the strongest predictor of security tool use, it was instead developers' ability to observe their peers using security tools.

Quantifying developers' adoption of security tools

The present study examined the perceptions of cellular phone users and nonusers on issues relating to vehicle control and driver distraction. Participants were asked if they own a cellular phone; if so, how much they use it; and their beliefs regarding cellular phone use while driving, including actions involving the use of cellular phones which could potentially cause vehicular accidents and the need for laws. A total of 330 individuals participated; 72% owned a cellular phone. The results indicate that nonusers of cellular phones believed more strongly than users that cellular phone use while driving negatively affects driving performance and that talking on the cellular phone could potentially cause an accident, and they also had a greater preference for new laws limiting such acts. Cellular phone users, more than nonusers, preferred no laws limiting cellular phone use and believed more strongly that other people driving while using a cellular phone were more dangerous than themselves doing the same. Implications of these results are discussed. Actual or potential applications of this research include interventions that limit driver distractibility.

Older adults, aged 65+ , are a rapidly growing segment of the world population. To adequately inform all members of the public, hazard researchers and practitioners must be aware of the information processing capabilities and limitations of this increasingly large group. This paper illustrates how documented age-related normative changes in perception, attention, memory, text comprehension, and decision making can affect the processing of hazard information within the context of the Protective Action Decision Model. For the stages of the model that are heavily reliant on the information processing capabilities of the message recipient, current cognitive aging findings are reviewed and potential elder-friendly information design solutions are suggested for general hazard information and warnings.

Cognitive Aging and the Processing of Hazard Information and Disaster Warnings

Warnings are safety communications that are used to inform people about hazards and to provide instructions so as to avoid or minimize undesirable consequences such as injury of death. Warnings are used in a variety of contexts to address environmental and product-related hazards. In the United States, interest in warnings is also associated with litigation concerns . The adequacy of warnings has become a prevalent issue in product liability and personal injury litigation. According to the Res tatement of Torts (second) and to the Theory of Strict Liability, if a product needs a warning and the warning is absent or defective , then the product is defective (see, e.g. , Madden , 1999). Regulations, standards, and guidelines as to when and how to warn have been developed more extensively in the last three decades. Also, there has been a substantial increase in research activity on the topic during this time. Human factors specialists, or ergonomist s, have
