How People revisit Web Pages: empirical findings and implications for the design of history systems
- International Journal of Human Computer Studies
, 1997
"... We report on users ’ revisitation patterns to World Wide Web (web) pages, and use the results to lay an empirical foundation for the design of history mechanisms in web browsers. Through history, a user can return quickly to a previously visited page, possibly reducing the cognitive and physical ove ..."

to revisit pages just visited, access only a few pages frequently, browse in very small clusters of related pages and generate only short sequences of repeated URL paths. We compared different history mechanisms, and found that the stack-based prediction method prevalent in commercial browsers is inferior
Revisitation patterns in world wide web navigation

We compared different history presentation styles, and found that the stack-based prediction method prevalent
Contrasting Stack-Based and Recency-Based Back Buttons on Web Browsers
, 2000
"... People frequently use the ubiquitous Back button found in most Web browsers to return to recently visited pages. Because all commercial browsers implement Back as a stack, previously visited branches of the tree are pruned. While this means that people can quickly navigate back up the tree, previous ..."

advantages and trade-offs exist in both methods, we performed a study that contrasted how people used stack vs recency-based Back. Surprising to us, several of our results were contrary to our expectations. First, people have a poor model of both stack and recency-Back. Second, people do not predict what
STAR3D: a stack-based RNA 3D structural alignment tool
, 2015
"... The various roles of versatile non-coding RNAs typ-ically require the attainment of complex high-order structures. Therefore, comparing the 3D structures of RNA molecules can yield in-depth understanding of their functional conservation and evolutionary his-tory. Recently, many powerful tools have b ..."

Although some methods rely on both backbone conformations and base pairing interactions, none of them consider the entire hierarchical formation of the RNA secondary structure. One of the major issues is that directly ap-plying the algorithms of matching 2D
A stacking-based approach to twitter user geolocation prediction
- In Proceedings of the 51st Annual Meeting of the Association for Computational Linguistics (ACL 2013): System Demonstrations
, 2013
"... We implement a city-level geolocation prediction system for Twitter users. The system infers a user’s location based on both tweet text and user-declared metadata using a stacking approach. We demonstrate that the stacking method substantially outperforms benchmark methods, achieving 49 % accuracy o ..."

Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance

"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

VC funds whose parent firms enjoy more influential network positions have significantly better performance, as measured by the proportion of portfolio company investments that are successfully exited through an initial
Combining Estimates in Regression and Classification
- Journal of the American Statistical Association
, 1993
"... We consider the problem of how to combine a collection of general regression fit vectors in order to obtain a better predictive model. The individual fits may be from subset linear regression, ridge regression, or something more complex like a neural network. We develop a general framework for this ..."

Pathogens, personality and culture: Disease prevalence predicts worldwide variability in sociosexuality, extraversion, and openness to experience

The authors investigate the possibility that these cultural differences can be traced, in part, to regional differences in the prevalence in infectious diseases. Th ..."
