Ecology of the family as a context for human development: Research perspectives.
- Developmental Psychology,
, 1986
"... This review collates and examines critically a theoretically convergent but widely dispersed body of research on the influence of external environments on the functioning of families as contexts of human development. Investigations falling within this expanding domain include studies of the interac ..."

Text Classification using String Kernels
"... We propose a novel approach for categorizing text documents based on the use of a special kernel. The kernel is an inner product in the feature space generated by all subsequences of length k. A subsequence is any ordered sequence of k characters occurring in the text though not necessarily contiguo ..."

N-grambased text categorization
- In Proc. of SDAIR-94, 3rd Annual Symposium on Document Analysis and Information Retrieval
, 1994
"... Text categorization is a fundamental task in document processing, allowing the automated handling of enormous streams of documents in electronic form. One difficulty in handling some classes of documents is the presence of different kinds of textual errors, such as spelling and grammatical errors in ..."

in email, and character recognition errors in documents that come through OCR. Text categorization must work reliably on all input, and thus must tolerate some level of these kinds of problems. We describe here an N-gram-based approach to text categorization that is tolerant of textual errors. The system
2007 . Phaser crystallographic software

"... Phaser is a program for phasing macromolecular crystal structures by both molecular replacement and experimental phasing methods. The novel phasing algorithms implemented in Phaser have been developed using maximum likelihood and multivariate statistics. For molecular replacement, the new algorithms ..."

algorithms have proved to be significantly better than traditional methods in discriminating correct solutions from noise, and for single-wavelength anomalous dispersion experimental phasing, the new algorithms, which account for correlations between F + and F, give better phases (lower mean phase error
Scale-free characteristics of random networks: The topology of the world-wide web
- PHYSICA A
, 2000
"... The world-wide web forms a large directed graph, whose vertices are documents and edges are links pointing from one document to another. Here we demonstrate that despite its apparent random character, the topology of this graph has a number of universal scale-free characteristics. We introduce a mod ..."

Measuring praise and criticism: Inference of semantic orientation from association
- ACM Transactions on Information Systems
, 2003
"... The evaluative character of a word is called its semantic orientation. Positive semantic orientation indicates praise (e.g., “honest”, “intrepid”) and negative semantic orientation indicates criticism (e.g., “disturbing”, “superfluous”). Semantic orientation varies in both direction (positive or neg ..."

The argument that follows is based on such a flexible, disaggregated theory of production. When
Information extraction: Identifying protein names from biological papers
- In Proceedings of the Pacific Symposium on Biocomputing '98 (PSB'98
, 1998
"... To solve the mystery of the life phenomenon, we must clarify when genes are expressed and how their products interact with each other. But since the amount of continuously updated knowledge on these interactions is massive and is only available in the form of published articles, an intelligent infor ..."

information extraction (IE) system is needed. To extract these information directly from articles, the system must rstly identify the material names. However, medical and biological documents often include proper nouns newly made by the authors, and conventional methods based on domain speci c dictionaries
Mating systems, philopatry and dispersal in birds
- Biol
, 1980
"... Abstract. Many species of birds and mammals are faithful to their natal and breeding site or group. In most of them one sex is more philopatric than the other. In birds it is usually females which disperse more than males; in mammals it is usually males which disperse more than females. Reproductive ..."

. Reproductive enhancement through increased access to mates or resources and the avoidance of inbreeding are important in promoting sex differences in dispersal. It is argued that the direction of the sex bias is a consequence of the type of mating system. Philopatry will favour the evolution of cooperative
Cognitive Modeling: Knowledge, Reasoning and Planning for Intelligent Characters

It remains difficult, however, to direct autonomous characters to perform specific tasks. This paper addresses the challenge by introduci ..."
