Capital Deepening and Wage Differentials: Germany vs. US Capital deepening may affect the evolution of the wage differential between skilled and unskilled workers differently in countries with different labor market institutions. If labor market institutions raise the relative wage of unskilled workers in Germany, firms have incentives to invest relatively more into capital equipment complement...

Automatically detecting discourse segments is an important preliminary step towards full discourse parsing. Previous research on discourse segmentation have relied on the assumption that elementary discourse units (EDUs) in a document always form a linear sequence (i.e., they can never be nested). Unfortunately, this assumption turns out to be too strong, for some theories of discourse like SDR...

Images of reversal twist through many folklore traditions, celebrating the poor fool who becomes king and condemning the powerful to ruin. For Mikhail Bakhtin, such reversals express the creative energy of "a carnival sense of the world." In carnival, laughter and excess push aside the seriousness and the hierarchies of "official" life. Carnival shakes up the authoritative version of language a...

In this report, I will survey the dominant theories employed in the academic subdiscipline of business ethics, describing and critiquing each one. By “theories” I mean not only the various philosophical approaches which inform discourse and research in this field, but also the alternative paradigms to which those approaches pertain according to the following schema. I will adopt for this survey...

Although much has been said about parallelism in discourse, a formal, computational theory of parallelism structure is still outstanding. In this paper, we present a theory which given two parallel utterances predicts which are the parallel elements. The theory consists of a sorted, higher-order abductive calculus and we show that it reconciles the insights of discourse theories of parallelism ...

Looking back the history of formal treatment of linguistics, we cannot disregard the contribution of possible world semantics. Intensional logic of Montague semantics, DRT (Discourse Representation Theory), mental space, and situation theory are closely related to or compared with the notion of possible world. All these theories have commonly clarified the structure of belief context or uncerta...

Over the past decades, the IS community has adapted theories, methodologies, and philosophies from reference disciplines to solidify its domain. This has contributed to the diversity and pluralism in our field. As the IS discipline has evolved with relatively permeable research boundaries over the years, the diversity in theoretical underpinnings has been not only healthy but also essential to ...

The following main ideas have been pointed out and put to work within our paper: (a) Information Structure (IS) theories (topic-focus, theme-rheme, background-contrast, informational and contrastive focus, focus projection rules, etc.) on text are shown to behave currently as a consistent linguistic tool that can stand behind a correct, language and contextual-depending, mapping of text into sp...

We present the first corpus of texts annotated with two alternative approaches to discourse structure, Rhetorical Structure Theory (Mann and Thompson, 1988) and Segmented Discourse Representation Theory (Asher and Lascarides, 2003). 112 short argumentative texts have been analyzed according to these two theories. Furthermore, in previous work, the same texts have already been annotated for thei...
