This study examined the relationship between health anxiety and searching for health information online, a phenomenon dubbed 'cyberchondria'. The majority of those with 'high' (n=46) and 'low' (n=36) levels of health anxiety reported seeking health information online. However, those with higher levels of health anxiety sought online health information more frequently, spent longer searching, an...

This paper considers how many character comparisons are needed to find all occurrences of a pattern of length m in a text of length n. The main contribution is to show an upper bound of the form of n + O(n/m) character comparisons, following preprocessing. Specifically, we show an upper bound of n + 8 3(m+1) (n −m) character comparisons. This bound is achieved by an online algorithm which perfo...

An ever-growing number of users participate in online communities such as Flickr, del.icio.us , and YouTube , making friends and sharing content. Users come to these sites to find out about general trends – the most popular tags, or the most recently tagged item – as well as for more specific information, such as the recent posts of one of their friends. While these activities correspond to dif...

We consider the problem of searching for an object on a line at an unknown distance OPT from the original position of the searcher, in the presence of a cost of d for each time the searcher changes direction. This is a generalization of the well-studied linear-search problem. We describe a strategy that is guaranteed to find the object at a cost of at most 9 · OPT + 2d, which has the optimal co...
