We develop a general approach to robust inference about a scalar parameter when the data is potentially heterogeneous and correlated in a largely unknown way. The key ingredient is the following result of Bakirov and Székely (2005) concerning the small sample properties of the standard t−test: For a significance level of 5% or lower, the t−test remains conservative for underlying observations t...

We evaluate by Monte Carlo simulations various singular thermodynamic quantities X, for an ensemble of quenched random Ising and Ashkin-Teller models. The measurements are taken at T c and we study how the distributions P(X) (and, in particular, their relative squared width, R X) over the ensemble depend on the system size l. The Ashkin-Teller model was studied in the regime where bond randomne...

OBJECTIVE The Food Craving Questionnaire-Trait (FCQ-T) is commonly used to assess habitual food cravings among individuals. Previous studies have shown that a brief version of this instrument (FCQ-T-r) has good reliability and validity. This article is the first to use Confirmatory factor analysis to examine the psychometric properties of the FCQ-T-r in a cross-validation study. METHOD Habitu...

To explore the effects of formative assessment on student engagement in classroom, 60 upper-intermediate level EFL students, were chosen out of a convenience sample of 120, using the Oxford Placement Test and were randomly assigned to experimental and control groups. After the intervention, the students were asked to complete the Student Course Engagement Questionnaire. Independent sample t-tes...

This work introduces capillary flow in paper microfluidics that features a flow rate Q that is constant in time, t, and independent of the viscosity of liquid sample, µ liquid : Q≠f(t, µ liquid). Compared to conventional paper microfluidics, we enclose the paper in solid walls and add a long and narrow air vent as outlet of the capillary pump, such that the flow rate is dominated by the downstr...
