An experimental design was employed in the investigation of the impact of two status cues, language style and source expertise, on people’s perceptions of online political discussants and their intentions and motivations to participate in local online political discussion fora. Specifically, the colloquial form of Singapore English, known as Singlish, was manipulated, together with information ...

GPSS (General Purpose Simulation System) is celebrating its 40 birthday this year. We recognize this notable birthday by assembling a panel of discussants consisting of some of the folks who have contributed significantly to GPSS and its use over the years. The panelists are Springer Cox (GPSS/PC and GPSS World), Jim Henriksen (GPSS/H and Proof Animation), Peter Lorenz (promoter of GPSS in Euro...

The papers collected in this volume grew out of a workshop “Direct Compositionality: A Workshop” sponsored by NSF Grant BCS-0236462 and held in June 2003 at Brown University. In addition to the eleven papers published here, the workshop featured three additional papers: by Daniel Büring, Alexis Dimitriadis, and Danny Fox. Moreover, all of the contributors here plus the three mentioned above ser...

W e use national survey data to examine the extent to which various sources of political information expose people to dissimilar political views. We hypothesize that the individual’s ability and desire to exercise selective exposure is a key factor in determining whether a given source produces exposure to dissimilar views. Although a lack of diverse perspectives is a common complaint against A...

This paper explores the role of technologies in supporting informal science learning from seven perspectives. Together, the authors ask a common question: How can learning technologies—tools, spaces, and places—be designed to support learners within and across environments? Eight exemplars are offered to answer this question through an analysis of a specific instance of technology in a non-scho...

Several discussants (Delaigle, Hall, Wellner, Seregin, Chacón, Critchley) ask about other possible shape constraints. Indeed, Seregin and Wellner (2010) have recently shown that a maximum likelihood estimator exists within the class of d-variate densities of the form f = h ◦ g, where h is a known monotone function and g is an unknown convex function. Certain conditions are required on h, but ta...

We thank the discussants for their varied and thought provoking responses although their number and variety makes a short response difficult. One of our goals, amply fulfilled, was to have extensive discussion of the many questions we raised but did not try to answer. In particular, Fan, Klaassen, and McNeney and Wellner all addressed questions A and B which we respond to further below. Another...
