Seismic moment assessment of earthquakes in stable continental regions?I. Instrumental seismicity

Abstract: SUMMARY This Part I study, in conjunction with Part 11, develops a method to determine, within specified uncertainty bounds, the seismic moment, and thus moment magnitude, of all earthquakes of stable continental regions (SCR) for which instrumental or intensity data exist. Its basis is polynomial regression analysis using a database of SCR earthquakes with direct seismic moment determination. The independent variables include modern teleseismic magnitudes and regional magnitudes (Part I), and isoseismal areas or number of recording stations (Part 11). Part I11 is an application of the methodology of Parts I and I1 to several major historical earthquakes. All data used in the regressions are assigned individual uncertainties estimated from the literature or from experience; formal confidence limits (68 per cent or 95 per cent) on both the regression formulas and the predicted seismic moment values are then possible via error propagation analysis. The most complete development is for the teleseismic magnitudes M, and mb. For both, the final regression for log(M,) is a quadratic formula that closely emulates the relationship between amplitude magnitudes and log(M,) expected from dislocation theory and source-scaling arguments. Regressions are also derived for the regional magnitudes mLg and M,, because there are many SCR events, mainly pre- 1964, that have no teleseismic magnitudes. Prediction uncertainties from teleseismic magnitudes in moment magnitude units are in the AO.18-0.28 range, and from regional magnitudes in the kO.23-0.38 range over a wide magnitude band. Finally, the methodology developed here is generic, even though the database is specific. Application to plate-boundary, oceanic intraplate, or active continental intraplate regions should be straightforward.

Hand in motion reveals mind in motion.

Abstract: Recently, researchers have measured hand movements en route to choices on a screen to understand the dynamics of a broad range of psychological processes. We review this growing body of research and explain how manual action exposes the real-time unfolding of underlying cognitive processing. We describe how simple hand motions may be used to continuously index participants’ tentative commitments to different choice alternatives during the evolution of a behavioral response. As such, hand-tracking can provide unusually high-fidelity, real-time motor traces of the mind. These motor traces cast novel theoretical and empirical light onto a wide range of phenomena and serve as a potential bridge between far-reaching areas of psychological science—from language, to high-level cognition and learning, to social cognitive processes.

Effects of family and marital psychotherapies: a meta-analysis.

Abstract: This meta-analysis of 163 randomized trials (including 59 dissertations) examines a number of questions not studied in previous syntheses. These include differences in outcome associated with different theoretical orientations, differences between marital and family therapies versus individual therapies, the clinical significance of therapy outcome, differences between marital versus family therapies in both outcomes and problems treated, and the effects of various substantive and methodological moderators of therapy outcome. The review concludes with some observations about the methodological status of this literature.

Why Do People Use Figurative Language

Abstract: In this article, we examine the discourse goals that are accomplished by the use of eight forms of figurative language: hyperbole, idiom, indirect request, irony, understatement, metaphor, rhetorical question, and simile. Subjects were asked to provide reasons why they would use a particular figure of speech. Based on their responses, a discourse goal taxonomy that includes each of the eight figures was developed. The goal taxonomy indicates that each figure of speech is used to accomplish a unique constellation of communicative goals. The degree of goal overlap between the eight forms was also calculated, and the results provide support for theoretical claims about the relatedness of certain figures. Taken together, the goal taxonomy and overlap scores broaden our understanding of functional and theoretical differences between the various kinds of figurative language.
