Cultur Divers Ethnic Minor Psychol 2021 Jul 29. Epub 2021 Jul 29.

Erasmus Research Centre for Media, Communication, and Culture (ERMeCC).

In this article, we present a digital tool (Diversity Perspectives in Annual Reports [DivPAR]) for automated content analysis of annual reports, designed to identify the presence of three cultural diversity perspectives-the Moral, Market, and Innovation perspectives-based on earlier work by Ely and Thomas (2001). In Study 1, we describe the development and validation of the instrument, through an iterative procedure in which manual annotation of independent subsamples ( = 24, 25) by human coders was compared to the computer coding in subsequent rounds, until sufficient agreement was reached. In Study 2, we illustrate the type of data that the script generates, by analyzing the prevalence of the three perspectives in annual reports of 55 Dutch organizations over a period of 2 decades (1999-2018; = 937).

Discretisation and continuity: The emergence of symbols in communication.

Cognition 2021 Jul 21;215:104787. Epub 2021 Jul 21.

Digital and Cognitive Musicology Lab, École Polytechnique Fédérale de Lausanne, 1015 Lausanne, Switzerland.

Vocal signalling systems, as used by humans and various non-human animals, exhibit discrete and continuous properties that can naturally be used to express discrete and continuous information, such as distinct words to denote objects in the world and prosodic features to convey the emotions of the speaker. However, continuous aspects are not always expressed with the continuous properties of an utterance but are frequently categorised into discrete symbols. While the existence of symbols in communication is self-evident, the emergence of discretisation from a continuous space is not well understood. Read More
