Self-tuning histograms have been proposed in the past as an attempt to leverage feedback from query execution. However, the focus thus far has been on histograms that only store cardinalities. In this paper, we study consistent histogram construction from query feedback that also takes distinct value counts into account. We first show how the entropy maximization (EM) principle can be leveraged...

abstract background: in nursing, self-efficacy is quite critical for skill performance. some factors might influence and predict self-efficacy in nurses. thus, the present study aimed to investigate self-efficacy and the factors predicting nurses’ self-efficacy in clinical setting. materials and methods: in this cross-sectional study, 264 nurses were selected from five hospitals affiliated to s...

Influence Maximization is one of the major tasks in the field of viral marketing and community detection. Based on the observation that social networks in general are multi-parameter graphs and viral marketing or Influence Maximization is based on few parameters, we propose to convert the general social networks into “interest graphs”. We have proposed an improvised model for identifying influe...

The self-interest motive is singularly powerful according to many of the most influential theories of human behavior and the layperson alike. In the present article the author examines the role the assumption of self-interest plays in its own confirmation. It is proposed that a norm exists in Western cultures that specifies self-interest both is and ought to be a powerful determinant of behavio...

This paper argues that self-interest and concern for others influence behavior through different cognitive systems. Self-interest is automatic, viscerally compelling, and often unconscious. Understanding one’s ethical and professional obligations to others, in contrast, often involves a more thoughtful process. The automatic nature of self-interest gives it a primal power to influence judgment ...

Antiviral agents have been hailed to hold considerable promise for the treatment and prevention of emerging viral diseases like H5N1 avian influenza and SARS. However, antiviral drugs are not completely harmless, and the conditions under which individuals are willing to participate in a large-scale antiviral drug treatment program are as yet unknown. We provide population dynamical and game the...

The recent threat of bioterrorism has fueled debate on smallpox vaccination policy for the United States. Certain policy proposals call for voluntary mass vaccination; however, if individuals decide whether to vaccinate according to self-interest, the level of herd immunity achieved may differ from what is best for the population as a whole. We present a synthesis of game theory and epidemic mo...
