To date, there is no research examining how adults with Amyotrophic Lateral Sclerosis (ALS) or Motor Neurone Disease (MND) and severe communication disability use Twitter, nor the use of Twitter in relation to ALS/MND beyond its use for fundraising and raising awareness. In this paper we (a) outline a rationale for the use of Twitter as a method of communication and information exchange for adu...

Twitter provides an open and rich source of data for studying human behaviour at scale and is widely used in social and network sciences. However, a major criticism of Twitter data is that demographic information is largely absent. Enhancing Twitter data with user ages would advance our ability to study social network structures, information flows and the spread of contagions. Approaches toward...

In the last few years, Twitter has become a powerful tool for publishing and discussing information. Yet, content exploration in Twitter requires substantial efforts and users often have to scan information streams by hand. In this paper, we approach this problem by means of faceted search. We propose strategies for inferring facets and facet values on Twitter by enriching the semantics of indi...

This paper explores the use of twitter in a team based learning scenario. Twitter has been recently used by many educational institutions but most of these have been related to provide the information to the general audience. There has not been much study done to propose twitter as an educational in a classroom scenario. This paper tries to establish the use of twitter with a well establish mod...

Twitter is a social media platform that can be used by people working in health and medicine to distribute information, advocate, debate and network with large numbers of other users. We set out to determine the top 10 Australian Twitter accounts in four categories, ranked by number of Twitter followers. We extracted names with high follower volumes from 'lists' of health and medical Twitter ac...

Twitter has found substantial use in a number of settings. For example, Twitter played a major role in the ‘Arab Spring’ and has been adopted by a large number of the Fortune 100. All of these and other events have led to a large database of Twitter tweets that has attracted the attention of a number of companies and researchers through what has become known as ‘Twitter mining’ (also known as ‘...

We present a set of case studies in which students create, customize, and personalize their own scientific instruments—and thus become engaged in scientific inquiry not only through observing and measuring but also through designing and building. Although computational technologies have, in general, contributed to making today’s scientific instruments more “opaque” (that is, less understandable...

The present research examined the effect of social influence on White, heterosexual individuals’ attraction to targets of varying races (White vs. Black) in two college student samples from the United States (one that leaned politically liberal and one that leaned politically conservative). Using a within-subjects experimental design, participants were given artificial peer evaluation data (pos...

BACKGROUND Twitter is increasingly used to estimate disease prevalence, but such measurements can be biased, due to both biased sampling and inherent ambiguity of natural language. OBJECTIVE We characterized the extent of these biases and how they vary with disease. METHODS We correlated self-reported prevalence rates for 22 diseases from Experian's Simmons National Consumer Study (n=12,305...
