The question of how we deploy logic in developing and justifying scientific theories of any sort is an important one. In this commentary, I consider William Stiles’ (2009) arguments about the logical operations that are deployed especially in theory-building case-study research in psychotherapy. My commentary contains three sections, defined by three sets of distinctions: (a) the distinction be...

There is little agreement on the mechanisms involved in second language (L2) processing of regular and irregular inflectional morphology and on the exact role of age, amount, and type of exposure to L2 resulting in differences in L2 input and use. The article contributes to the ongoing debates by reporting the results of two experiments on Russian verb generation and recognition in a lexical de...

Information Systems researchers often study artifacts in light of their purpose, use, and effects. Their research is often conducted relying on a socio-technical or sociomaterial based ontology. For these realism-based approaches, ever-present security vulnerabilities, conflate the properties of the digital artifact making it impossible to conceive of a universal artifact. This paper explores h...

A key challenge faced by children in vocabulary acquisition is learning which of the many possible meanings is appropriate for a word. The word generalization problem refers to how children associate a word such as dog with a meaning at the appropriate category level in the taxonomy of objects, such as Dalmatians, dogs, or animals. We present extensions to a cross-situational learner that enabl...

We present an analysis of parser performance on speech data, comparing word type and token frequency distributions with written data, and evaluating parse accuracy by length of input string. We find that parser performance tends to deteriorate with increasing length of string, more so for spoken than for written texts. We train an alternative parsing model with added speech data and demonstrate...

A particularly important form of token-reflexive symbol is found in the tenses of verbs. The tenses determine time with reference to the time point of the act of speech, i.e., of the token uttered. A closer analysis reveals that the time indication given by the tenses is of a rather complex structure. Let us call the time point of the token the point of speech. Then the three indications, ‘befo...

Many historians reject quantitative methods as inappropriate to understanding past societies.This article argues that no sharp distinction between qualitative and quantitative concepts can be drawn, as almost any concept used to describe a past society is implicitly quantitative. Many recent advances in understanding have been achieved by deriving quantitative evidence from qualitative evidence...
