The present paper, which is intended for a diverse audience of evaluation researchers, applied social scientists and research funders, provides a broad overview of the conceptual and statistical issues involved in using multi-site randomized trials to learn about and from variation in program effects across individuals, across policy-relevant and theoretically-relevant subgroups of individuals ...

The analysis of stem alternations (e.g. sang as past of sing) is controversial; there is a lasting tension between morphophonological theories (sang is derived from sing by rule) and stem storage theories (sang and sing are stored allomorphs). This paper argues that in many cases of stem alternation (e.g., Spanish diphthongization) the locality conditions on contextual allomorphy provide crucia...

We study the double cosets of a Lie group by a compact Lie subgroup. We show that a Weil formula holds for double coset Lie hypergroups and show that certain representations of the Lie group lift to representations of the double coset Lie hypergroup. We characterize smooth (analytic) vectors of these lifted representations.

We derive all eighteen Gauss hypergeometric representations for the Ferrers function of second kind, each with a different argument. They are obtained from associated Legendre kind by using limit representation. For 18 arguments which correspond to these representations, we give geometrical descriptions corresponding convergence regions in complex plane. In addition, consider single sum Fourier...

noindent We have two goals in this paper. First, we investigate and construct cofree coalgebras over $n$-representations of quivers, limits and colimits of $n$-representations of quivers, and limits and colimits of coalgebras in the monoidal categories of $n$-representations of quivers. Second, for any given quivers $mathit{Q}_1$,$mathit{Q}_2$,..., $mathit{Q}_n$, we construct a new quiver $math...

D on’t tell your high school football coach, but it is possible to have teamwork even if nobody’s in charge. Inside a cell, for example, myosin VI motors work in concert to haul cargoes along the actin cytoskeleton, Sivaramakrishnan and Spudich reveal (1). Instead of providing muscle power, myosin VI is one of the unconventional myosins whose job is intracellular transportation. Researchers hav...

The present study uses the perceptual-migration paradigm to explore whether Chinese tones and rhymes are encoded separately during Mandarin speech perception. Following the logic of illusory conjunctions, we calculated the cross-ear migration rates of tones, rhymes, and their combination in Chinese and English listeners. For Chinese listeners, we found that tones migrated more than rhymes. The ...

In three experiments, we investigated whether the production of subject-verb number agreement is affected by the phonological realization of grammatical information. Speakers repeated and completed German or Dutch noun phrases along the lines of The position against the demonstrations. We varied the number of the subject noun (position) and the local noun (demonstrations), as well as the number...
