We study the contemporaneous and intertemporal partial relation between T-bond pricing and changes in equity risk, as measured by the implied volatility from equity-index options. Our 1992 to 2007 sample is attractive because of the modest inflation risk and sizable time-series variability in equity risk. Over 1997 to 2007 and for inclusive one-half and one-quarter subperiods, we find that the ...

We investigate whether firms “lean against the wind”, i.e., manage earnings upward to offset aggregate (market wide) undervaluation, by examining how firm-specific measures of earnings management correlate with aggregate market conditions. Leaning against the wind has been proposed by prior research as a behavioral explanation for a negative contemporaneous relation and a positive predictive re...

In this paper, we present a new method for fuzzy query processing for document retrieval based on extended fuzzy concept networks. In an extended fuzzy concept network, there are four kinds of fuzzy relationships between concepts, i.e., fuzzy positive association, fuzzy negative association, fuzzy generalization, and fuzzy specialization. An extended fuzzy concept network can be modeled by a re...

The concept of taking conflict personally is largely underexplored by dominant conflict literature. The purpose of this study was to test the cross-cultural predictions of the associations between self-construal, the tendency to personalize conflict, and subsequent outcome variables such as negative feelings of being criticized and motivation to improve. The participants were 457 undergraduates...

Gratitude was examined among 154 students to identify benefits from its experience and expression. Students completed measures of subjective well-being, social support, prosocial behavior, and physical symptoms. Positive associations were found between gratitude and positive affect, global and domain specific life satisfaction, optimism, social support, and prosocial behavior; most relations re...

Relation extraction by universal schema avoids mapping to a brittle, incomplete traditional schema by instead making predictions in the union of all input schemas, including textual patterns. Modeling these predictions by matrix competition with matrix factorization has yielded state-of-the-art accuracies. One difficulty with prior work in matrix factorization, however, is that there is no nega...

We introduce a bipolarly extended veto principle – a positive, as well as negative, large performance differences polarization – which allows us to extend the definition of the classical outranking relation in such a way that the identity between its asymmetric part and its codual relation is preserved.

Suppose a strict preference relation fails to possess maximal elements, so that a choice is not clearly defined. I propose to delete particular instances of strict preferences until the resulting relation satisfies one of a number of known regularity properties (transitivity, acyclicity, or negative transitivity), and to unify the choices generated by different orders of deletion. Removal of st...

Recent work has demonstrated that math anxiety is more than just the product of poor math skills. Psychosocial factors may play a key role in understanding what it means to be math anxious, and hence may aid in attempts to sever the link between math anxiety and poor math performance. One such factor may be the extent to which individuals integrate math into their sense of self. We adapted a we...
