One way in which financial aid is thought to promote college success is by minimizing the time students spend working. Yet, little research has examined if this intended first-order effect occurs, and results are mixed. We leverage a randomized experiment and find that students from low-income families in Wisconsin offered additional grant aid…

This article presents a hybrid methodological technique that fuses elements of experimental design with qualitative strategies to explore mediated communication. Called the "qualitative experiment," this strategy uses focus groups and in-depth interviews "within" randomized stimulus conditions typically associated with…

The need for determining the relative intelligibility of passbands spanning the speech spectrum has been addressed by publications of the American National Standards Institute (ANSI). When the Articulation Index (AI) standard (ANSI, S3.5, 1969, R1986) was developed, available filters confounded passband and slope contributions. The AI procedure…

Computers have changed the landscape of scientific research in profound ways. Technology has always played an important role in scientific experimentation--through the development of increasingly sophisticated tools, the measurement of elusive quantities, and the processing of large amounts of data. However, the advent of social networking and the…

Although phonological representations have been a primary focus of verbal working memory research, lexical-semantic manipulations also influence performance. In the present study, the authors investigated whether a classic phenomenon in verbal working memory, the phonological similarity effect (PSE), is modulated by a lexical-semantic variable,…

Wisconsin's influential Learnfare initiative is a conditional cash penalty program that sanctions a family's welfare grant when covered teens fail to meet school attendance targets. In the presence of reference-dependent preferences, Learnfare provides uniquely powerful financial incentives for student performance. However, a 10-county…

Value-added models, which rate schools for effectiveness while taking into account the poverty and other socioeconomic status of the students, are generating increased interest. This paper describes the use of one such model to evaluate whether school ratings changed when three new programs were introduced: the "Target Teach" curriculum…
