Objectives: The Internet is a fundamental tool for completing many different instrumental activities of daily living (IADL), including shopping and banking. Persons with HIV−associated Neurocognitive Disorders (HAND) are at heightened risk for IADL problems, but the extent to which HAND interferes with the performance of Internet-based household IADLs is not known. Methods: Ninety-three individuals with HIV disease, 43 of whom were diagnosed with HAND, and 42 HIV− comparison participants completed Internet-based tests of shopping and banking. Participants used mock credentials to log in to an experimenter-controlled Web site and independently performed a series of typical online shopping (e.g., purchasing household goods) and banking (e.g., transferring funds between accounts) tasks. Results: Individuals with HAND were significantly more likely to fail the online shopping task than neurocognitively normal HIV+ and HIV− participants. HAND was also associated with poorer overall performance versus HIV+ normals on the online banking task. In the HAND group, Internet-based task scores were correlated with episodic memory, executive functions, motor skills, and numeracy. In the HIV+ sample as a whole, lower Internet-based task scores were uniquely associated with poorer performance-based functional capacity and self-reported declines in shopping and financial management in daily life, but not with global manifest functional status. Conclusions: Findings indicate that HAND is associated with difficulties in using the Internet to complete important household everyday functioning tasks. The development and validation of effective Internet training and compensatory strategies may help to improve the household management of persons with HAND. (JINS, 2017, 23, 605–615)

Web-based studies have become increasingly common in the social sciences, but have been rare in genetic epidemiology in general and twin studies in particular. We here review the methods, validity checks and preliminary correlational data from an on-line questionnaire collected from 2005–2008. During this time period, 44,112 individuals completed the questionnaire. This sample was 65.3% female, 85.4% 18 years or older, 72.0% Caucasian and had a mean educational level of 12.2 years. The sample included 609 twin, 333 sibling and 201 parent-offspring pairs as well as 342 dating partners, 313 ‘significant other’ pairs, 327 spouses and 2,316 friend pairs. A range of checks suggested low levels of invalid data. Correlations for personality, substance use and misuse, lifetime major depression, social attitudes, educational status, and height and weight were broadly similar to those obtained previously using conventional assessment methods. Web-based studies are a relatively easy and inexpensive way to ascertain large numbers of individuals, although obtaining twin pairs is more difficult, and female and monozygotic pairs are overrepresented. The sample is diverse and pair resemblance is generally similar to that obtained using interviews or mailed questionnaires.

LogicWeb mobile code consists of Prolog-like rules embedded in Web pages, thereby adding logic programming behaviour to those pages. Since LogicWeb programs are downloaded from foreign hosts and executed locally, there is a need to protect the client from buggy or malicious code. A security model is crucial for making LogicWeb mobile code safe to execute. This paper presents such a model, which supports programs of varying trust levels by using different resource access policies. The implementation of the model derives from an extended operational semantics for the LogicWeb language, which provides a precise meaning of safety.

The potential uses of the Internet to behavioural and cognitive psychotherapists and researchers are manifold. This article summarizes what the Internet is, how to connect to it, searching the Web, on-line publishing, discussion forums, chat-rooms, literature searching, transfer of documents and creating a web-site. It considers the potential of Internet technology in therapy and enhancing patient/therapist contact. A web page containing links to many of the sites referred to in this article as well as additional links and resources is accessible through the BABCP website (www.babcp.org.uk).

A six axis robot has been connected to the World Wide Web at http://telerobot.mech.uwa.edu.au/. The robot was made available on the World Wide Web in September 1994 and has been through many revisions since that time. The remote user receives static images of the robot's work space and can manipulate wooden blocks.

The implementation and application of this interface to telerobotics is discussed. Useability and operator behaviour are investigated through analysis of movement records. Questions addressed are: What is the level of interest in this technique and is it a practical interface for telerobotics.

There is a huge need for access to information in the areas of disaster relief disaster medicine, and humanitarian assistance. The extraordinarily rapid increase in the literature in these subject areas attests to this need. However, use of the printed word has substantial limitations that are even more profound in the developing world.

Currently, the information available tends to be fragmented and sequestered by the specific interests of the organizations and governments involved. The evolving electronic methods for the storage, organization, and retrieval of information makes coordination between organizations concerned with disasters within our grasp.

This paper discusses the Center of Excellence in Disaster Management and Humanitarian Assistance and describes the World Wide Web and the implications it has in disaster management and medicine. It describes methods for obtaining user input to the techniques used for the development of the world wide web for the areas of disaster management and disaster medicine. The implementation of an on-line Internet reference desk that will provide: 1) a list of “experts;” 2) a searchable disaster database; and 3) on-line simulation courses and training exercises also is discussed.
