Improved algorithms for topic distillation in a hyperlinked environment
- In SIGIR Conference on Research and Development in Information Retrieval
, 1998
"... Abstract This paper addresses the problem of topic distillation on the World Wide Web, namely, given a typical user query to find quality documents related to the query topic. Connectivity analysis has been shown to be useful in identifying high quality pages within a topic specific graph of hyperli ..."

What good are positive emotions
- Review of General Psychology
, 1998
"... This article opens by noting that positive emotions do not fit existing models of emotions. Consequently, a new model is advanced to describe the form and function of a subset of positive emotions, including joy, interest, contentment, and love. This new model posits that these positive emotions ser ..."

The quality of qualitative research.

"... A variety of conceptions of qualitative research exist, with competing claims as to what counts as good quality work. Rather than opting for the criteria promoted by A lot of effort has been expended by methodologists over the years, trying to give some guidance to qualitative researchers in improv ..."

Technological pedagogical content knowledge: A framework for integrating technology in teacher knowledge.
- Teachers College Record,
, 2006
"... Abstract This paper describes a framework for teacher knowledge for technology integration called technological pedagogical content knowledge (originally TPCK, now known as TPACK, or technology, pedagogy, and content knowledge). This framework builds on Lee Shulman's construct of pedagogical c ..."

Moreover, this knowledge is unlikely to be used unless teachers can conceive of technology uses that are consistent with their existing pedagogical beliefs An Approach to Thinking About Technology Integration Faced with these challenges
The Determinants of Credit Spread Changes.
- Journal of Finance
, 2001
"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

Existing literature on credit spread changes is limited. 3 Pedrosa and Roll (1998) document considerable co-movement of credit spread changes among index portfolios of bonds from various industry, quality
The curvelet transform for image denoising
- IEEE TRANS. IMAGE PROCESS
, 2002
"... We describe approximate digital implementations of two new mathematical transforms, namely, the ridgelet transform [2] and the curvelet transform [6], [5]. Our implementations offer exact reconstruction, stability against perturbations, ease of implementation, and low computational complexity. A cen ..."

Existing theory for curvelet and ridgelet transforms suggests that these new approaches can outperform wavelet
SUS: A quick and dirty usability scale
, 1996
"... Usability does not exist in any absolute sense; it can only be defined with reference to particular contexts. This, in turn, means that there are no absolute measures of usability, since, if the usability of an artefact is defined by the context in which that artefact is used, measures of usability ..."

Usability and context Usability is not a quality that exists in any real or absolute sense. Perhaps it can be best summed up as being a
R: RNA sequence analysis using covariance models. Nucleic Aeids Res
, 1994
"... We describe a general approach to several RNA sequence analysis problems using probabilistic models that flexibly describe the secondary structure and primary sequence consensus of an RNA sequence family. We call these models 'covariance models'. A covariance model of tRNA sequences is an ..."

A model can be built automatically from an existing sequence alignment. We also describe an algorithm for learning a model and hence a consensus secondary structure from initially
Purify: Fast detection of memory leaks and access errors

On Clusterings: Good, Bad and Spectral

A simple recursive heuristic is shown to have poly-logarithmic worst-case guarantees under the new measure. The main result of the paper is the analysis of ..."
