The central thesis of this article is that measurement units are theoretical concepts because measurement presumes theoretical definition. New theoretical constructs can be defined in terms of algebraic combinations of previously defined measurement units. Physics has developed an impressive hierarchical knowledge structure on this basis. The unitless measures favored by psychology preclude the generation of such a knowledge hierarchy. It also leads to definitions of reliability and validity in correlational terms which can result in inaccurate measurement. Psychology has long used (...) time as a fundamental unit. Adoption of a second measurement unit would enable construction of a psychological knowledge hierarchy to begin. (shrink)

The major premise of this paper is a well accepted definition taken from the mathematics of information theory; information exists only when uncertainty is reduced by some amount. The minor premise of this paper is that all valid explanations be informative to some degree. Hence, the thesis of this paper is that all valid explanations must reduce uncertainty. The quantification of information is explained, direct and indirect explanations examined, equivalence with regression, correlation, and analysis of variance described, weak and strong (...) versions of uncertainty reduction presented, relationships with determinism and development mentioned, qualitative explanation accepted, and invalid examples of redescription as explanation illustrating reductionism, traits, and cognition are provided. 2012 APA, all rights reserved).

The National Science Foundation (NSF) has, since 1997, attempted to diversify and enrich science research and education in the USA through the Broader Impacts Criterion (BIC), also known as “Criterion Two” or the “Second Criterion”. In doing so, NSF has so successfully integrated BIC into its discovery grant funding programmes that it has become difficult to assess the efficiency (in an economic sense) of BIC activities, as opposed to cataloguing its products (number of trainees, publications, etc.). Moreover, current practice at (...) NSF requires that each and every Principal Investigator receiving a discovery grant address both Science, Technology, Engineering and Math activities and broader impacts, despite the fact that their formal training is most likely to be in only one of these areas. Against this backdrop, I consider NSF spending on broader impacts, conduct a microeconomic analysis of effectiveness of BIC expenditures, and discuss alternative funding models and Principal Investigator profiles and expertise sets that might not only accelerate the goals of expanding NSF's broader impact, but additionally enhance the quality of science funded by this agency.

Instruments are mainly used to provide data for testing theoretical predictions. However, sometimes instrument development sets the occasion for profound theoretical changes which are totally unanticipated. This article presents examples of instrument driven theory derived from biology and physics as well as discussing implications for psychology. The role of theory in the design of instruments is considered.

We present two studies that examine the effects of guanxi on multiple social groups from the perspective of Chinese business people. Study 1 (N = 203) tests the difference in perceived effects of six guanxi contextualizations. Study 2 (N = 195) examines the duality of guanxi as either helpful or harmful to social groups, depending on the contextualization. Findings suggest guanxi may result in positive as well as negative outcomes for focal actors and the aggregate.
