We extend the random permutation model to obtain the best linear unbiased estimator of a finite population mean accounting for auxiliary variables under simple random sampling without replacement (SRS) or stratified SRS. The proposed method provides a systematic design-based justification for well-known results involving common estimators derived under minimal assumptions that do not require sp...

Processing musical meter—the organization of time into regular cycles strong and weak beats—requires abstraction from the varying rhythmic surface. Several studies have investigated whether meter processing requires attention, or if it can be both pre-attentive attentive. While findings on temporal expectation (processing per se) indicate benefits in complex, dual-task contexts (meter used for ...

A field experiment was performed to investigate the effect of several variables on helping behavior, using the express trains of the New York 8th Avenue Independent Subway as a laboratory on wheels. Four teams of students, each one made up of a victim, model, and two observers, staged standard collapses in which type of victim (drunk or ill), race of victim (black or white) and presence or abse...
