A recent paper evaluating a new rubric-based graduate admissions approach using generic methods tentatively suggested that its decisions differed noticeably from the previous approach in an unspecified way. Using prior knowledge that the often-stated

A recent paper used structural equation modeling to infer the effects of gender-dependent student attitudes on several outcomes of introductory physics courses. The model used is precisely Markov equivalent to an equally plausible approximation in wh

Sound educational policy recommendations require valid estimates of causal effects, but observational studies in physics education research sometimes have loosely specified causal hypotheses. The connections between the observational data and the exp

The anomalously large dielectric aging in ferroelectric partially deuterated potassium dihydrogen phosphate (DKDP) is found to have multiple distinct mechanisms. Two components cause decreases in dielectric response over a limited range of fields aro

We demonstrate the use of the one-and-a-half spectrum as a way of looking at the time-asymmetry of Barkhausen noise. This method is of particular value because it allows us to look in the regime where individual Barkhausen pulses are no longer distin

The temperature dependence of discrete spin fluctuation modes is investigated in the spin glass phase of CuMn, doped with Au to produce strong local anisotropy. As with the locally anisotropic spin glass AuFe, and unlike the nearly isotropic CuMn, in

We compare bridge voltage response measurements to ac magnetic fields from a giant magnetoresistive sensor with noise measurements on the same sensor. The small-signal response (for applied ac magnetic fields between 0.1 mOe rms and 30 mOe) is much l

Equilibrium conductivity fluctuations of mesoscopic domains are found in film and bulk single-crystal manganite colossal magnetoresistive material. Temperature and field dependences of the Boltzmann factors for a collection of two-state fluctuators g
