A method of interpreting radial distribution functions (RDF) of amorphous metals is proposed in which the role of the local atomic structure is emphasized. It is found that the width and height of the peaks of the RDF are related to the second moment of the atomic-level hydrostatic stress distribution ⟨p2⟩. The results of this analysis are then used to explain the details of the changes that oc...

Evidence from social psychology suggests that econometricians will avoid evidence that disconfirms their beliefs. Two beliefs of econometricians were examined: (1) Econometric methods provide more accurate short-term forecasts than do other methods; and (2) more complex econometric methods yield more accurate forecasts. A survey of 21 experts in econometrics found that 95% agreed with the first...

Simpson’s paradox refers to the reversal of a statistical relationship between two variables in sub-populations when the sub-populations are combined and analyzed as a population. This article is intended to provide a broad survey of the past, present and future research surrounding the issue. Real data from a discrimination litigation case is examined to identify the occurrence of the paradox....

Statistical ensembles of flexible two-dimensional fluid membranes arise naturally in the description of many physical systems. Typically one encounters such systems in a regime of low tension but high stiffness against bending, which is just the opposite of the regime described by the Polyakov string. We study a class of couplings between membrane shape and in-plane order which break 3-space pa...

In a recent issue of the Journal of American Folklore Bruce Jackson pleads with folklorists to rid themselves of term "folkloristics" ( Jackson 1985). Toward the conclusion of his statement he addresses all of us passionately: "Let's abandon this neologism with its pompous and misleading suffixes, this clumsy construct that does not propel us into the modern age but instead makes us appear slig...

I n economics as in anthropology, old artifacts spur continuing debates. A case in point is Knut Wicksell’s celebrated 1898 analysis of the cumulative process of price inflation in pure credit, cashless economies. Some economists view Wicksell’s model as a milestone in the evolution of quantitytheoretic monetary analysis inasmuch as it constitutes the seminal rigorous explanation of how loan-cr...

The increasing importance of service systems in the global economy prompts researchers to focus on quality to measure the critical interaction between human behavior, IT and society. Building on service-dominant logic and sociomaterialism, this study develops and validates a quality model and measures its overall impact on individual (value, satisfaction), organizational (i.e., continuance inte...

The speed of torsional stress waves transmitted in solid waveguides submerged in a liquid depends, among other things, on the liquid's density and viscosity and the waveguides' cross-sectional geometry. By measuring the speed of torsional stress waves in two waveguides of different cross-sectional geometries, one can obtain both the liquid's density and viscosity. An online, real-time sensor fo...

I examine the response of husbands' and wives' earnings to a tax reform in which husbands' and wives' tax rates changed independently, allowing me to examine the effect of both spouses' incentives on each spouse's behavior. I analyze the large Swedish tax reform of 1990–1991 and find that in response to a compensated fall in one spouse's tax rate, each spouse's earnings rise. I compare these re...

This article examines the effectiveness of using wikis for collaborative projects in college journalism classrooms, with the principles of andragogy as a framework. The use of wikis in two journalism courses at a large university in the American Midwest illustrates how wikis can encourage learners to become more selfdirected by engaging in online collaborative writing about how best to produce ...
