Participants in public distributed computing do not find it easy to trust each other. The massive number of parties involved, their heterogeneous backgrounds, disparate goals and independent nature are not a good basis for the development of relationships through purely social mechanisms. This paper discusses the trust management issues that arise in the context of the XenoServer Open Platform:...

There is a paucity of systematic analysis of the relation between sexual activity and mental health. To address this gap, we ask whether sexual activity associates with lower levels of depression among older adults. We hypothesize that sexual activity—especially if it typically incorporates other forms of physical affection—may be a socially meaningful activity and may create intimacy that prov...

Recently, there has been great interest both in the development of cross-linguistically applicable annotation schemes and in the application of syntactic parsers at web scale to create parsebanks of online texts. The combination of these two trends to create massive, consistently annotated parsebanks in many languages holds enormous potential for the quantitative study of many linguistic phenom...

This paper presents a Chinese dependency syntax for treebanking. The syntax contains 13 word classes and 34 dependency types. A format of treebank based on the syntax is also proposed for the applications of computational and general linguistic research. Some experiments show that the treebank based on the proposed dependency syntax can be used for training and evaluating the dependency parser ...

A definition is given and the physical meaning of quantum transformations of a non-commutative configuration space (quantum group coactions) is discussed. It is shown that non-commutative coordinates which are transformed by quantum groups are the natural generalization of the notion of a tensor operator for usual groups and that the quantum group coactions induce semigroups of transformations ...

CONTEXT Heterosexual anal intercourse is a highly efficient mode of HIV transmission, yet little is known about the contexts in which women engage in it, or when and with whom they use condoms. Similarly, sexuality and reproductive health research has paid little attention to female desire and pleasure-seeking. METHODS In-depth interviews were conducted in Boston in 2006 with 28 women who rep...

This study examines the sense of self of women with physical disabilities in terms of self-esteem, self-cognition (perceptions of how others see them), and social isolation. It was hypothesized that these variables mediate the relation of precursor variables (age, education, severity of disability, and childhood experiences, including overprotection, familial affection, and school environment) ...

The good old days probably weren’t better, but they were certainly calmer. It’s true that the recovery from the international financial crisis that began in Thailand in July 1997 was faster than most observers (myself very much included) had imagined possible. The crisis, however, was terrifying while it lasted, and its aftereffects are still being felt. Indeed, while South Korea and Malaysia h...
