Confirmatory analysis of simultaneous,sequential, and achievement factors on the K-ABC at 11 age levels ranging from 212 to 1212 years

The K-ABC is a recently published measure of children's intelligence based on a theoretical model of information processing. Exploratory factor analyses conducted during the scale's development supported the underlying theoretical model of sequential, simultaneous, and achievement factors. Confirmatory analysis using a Jöreskog method was carried out in the present investigation and completely supported the two-factor processing model. When the achievement measures were included, the two mental processing factors again clearly emerged, along with a third factor defined by the achievement scale subtests, but they did not fit an independent three-factor model.     

On the consistency problem for the calculus

In this paper, we further investigate the consistency problem for the qualitative temporal calculus introduced by Pujari et al. [A.K. Pujari, G.V. Kumari, A. Sattar, INDU: An interval and duration network, in: Australian Joint Conference on Artificial Intelligence, 1999, pp. 291–303]. We prove the intractability of the consistency problem for the subset of pre-convex relations, and the tractability of strongly pre-convex relations. Furthermore, we also define another interesting set of relations for which the consistency problem can be decided by the -closure method, a method similar to the usual path-consistency method. Finally, we prove that the -closure method is also complete for the set of atomic relations of implying that the intervals have the same duration.

To explore the role of perfectionism across anxiety disorders, 175 patients with either panic disorder (PD), obsessive compulsive disorder (OCD), social phobia, or specific phobia, as well as 49 nonclinical volunteers, completed two measures [Frost, R. O., Marten, P., Lahart, C., & Rosenblate, R., (1990). The dimensions of perfectionism. Cognitive Therapy and Research, 14, 449-468; Hewitt, P. L., & Flett, G. L., (1991). Perfectionism in the self and social contexts: Conceptualization, assessment and association with psychopathology. Journal of Personality and Social Psychology, 60, 456-470.] that assess a total of nine different dimensions of perfectionism. Relative to the other groups, social phobia was associated with greater concern about mistakes (CM), doubts about actions (DA), and parental criticism (PC) on one measure and more socially prescribed perfectionism (SP) on the other measure. OCD was associated with elevated DA scores relative to the other groups. PD was associated with moderate elevations on the CM and DA subscales. The remaining dimensions of perfectionism failed to differentiate among groups. The clinical implications of these findings are discussed.

Aggressive driving: the contribution of the drivers and the situation

Aggressive driving is defined in terms of the frustration–aggression model. In that context aggressive driving is a syndrome of frustration-driven behaviors, enabled by the driver's environment. These behaviors can either take the form of instrumental aggression—that allows the frustrated driver to move ahead at the cost of infringing on other road users’ rights (e.g., by weaving and running red lights)—or hostile aggression which is directed at the object of frustration (e.g., cursing other drivers). While these behaviors may be reflective of individual differences in aggression, it is argued that the exclusive focus on the characteristics of the aggressive drivers and how to control them is short-sighted. Instead, this paper proposes a multi-factor approach to the problem. Five studies conducted so far tend to support this approach, by showing that specific aggressive behaviors—such as honking and running red lights—are associated with cultural norms, actual and perceived delays in travel, and congestion. Ergonomics-oriented approaches that involve environmental modifications are proposed.     

On Certainty: Wittgenstein and Einstein

The paper focuses on the role of relativistic ideas in Wittgenstein's philosophy. In particular, it focuses on On Certainty (1969), where in (305), Wittgenstein explicitly invokes Einstein's theory of relativity: “Here once more there is needed a step like the one taken in relativity theory.” The aim of the paper is to establish a connection between Wittgenstein and Einstein that is both theoretically and exegetically sound. In particular, the paper argues that Wittgenstein's reaction to scepticism closely resembles Einstein's reaction to the ether.
