Abstract This paper is positioned at the interface of second/foreign language (L2) assessment and Conversation Analysis-Second Language Acquisition (CA-SLA). It explores challenges ratability in assessing interactional competence (IC) from three dimensions: an overview conceptual terminological convergence/divergence CA-SLA L2 literature, a micro-analytic Analysis test-taker interactions, opera...

We examine the effects of various political campaign activities on voter preferences in the domain of US Presidential elections. We construct a comprehensive data set that covers the three most recent elections, with detailed records of voter preferences at the state-week level over an election period. We include various types of the most frequently utilized marketing instruments: two forms of ...

In many interactive decision making scenarios there is often no solution that satisfies all of the user’s preferences. The decision process can be helped by providing explanations. Relaxations show sets of consistent preferences and, thus, indicate which preferences can be enforced, while exclusion sets show which preferences can be relaxed to obtain a solution. We propose a new approach to exp...

We study a model in which voters choose between two candidates on the basis of both ideology and competence. While the ideology of the candidates is commonly known, voters are imperfectly informed about competence. Voter preferences, however, are such that it is a dominant strategy to vote according to ideology alone. When voting is compulsory, the candidate of the majority ideology prevails an...

We prove that a universal preference type space exists under much more general conditions than those postulated by Epstein and Wang (1996). To wit, it is enough that preferences can be encoded by a countable collection of continuous functionals, while the preferences themselves need not necessarily be continuous or regular, like, e.g., in the case of lexicographic preferences. The proof relies ...

We present an extrinsic evaluation of a clustering-based approach to computer-assisted scoring of short constructed response items, as encountered in educational assessment. Due to their open-ended nature, constructed response items need to be graded by human readers, which makes the overall testing process costly and time-consuming. In this paper we investigate the prospects for streamlining t...

The extant literature has consistently outlined a limited relationship between peoples' subjective reports of defective memory and their corresponding performances on objective measures of memory functioning. Several variables have been proposed to explain this finding, but few studies have investigated test-taker effort as a variable of interest. The primary aim of the current study was to exa...
