Using a novel measure incorporating stylistic and acoustic data on recorded music from 1967 to 2017, we search for trends in the evolution of musical diversity in 125,340 albums. We find that temporal patterns of diversity differ for stylistic and acoustic data. We also find that the patterns differ dramatically by genre. Some genres, such as blues, jazz, and pop-rock, decrease in diversity over time; most other genres increase in diversity. The causes of these different trends present a puzzle for future research. We also find different patterns for recordings that made the Billboard 200 charts compared to all recordings, suggesting an association between selection processes driven by consumer popularity and diversity. Moreover, associations of diversity and industry structure found in prior research do not hold when we analyze data beyond the smaller sample of the more popular recordings found in Billboard. These findings have implications for many prior studies based exclusively on best-selling recordings

We review literature linking patterns of vocal accommodation in the paraverbal range of the voice to small group structures of status and dominance. We provide a thorough overview of the current state of vocal accommodation research, tracing the development of the model from its early focus on patterns of mutual vocal adaptation, to the current focus on structural factors producing patterns of unequal accommodation between group members. We also highlight gaps in existing knowledge and opportunities to contribute to the development of vocal accommodation as an unobtrusive, nonconscious measure of small group hierarchies.

We trace the empirical development of vocal accommodation as a measure of status and power, and discuss connections between vocal accommodation and two prominent theoretical frameworks: communication accommodation theory (CAT) and expectation states theory. We also provide readers with a guide for collecting and analyzing vocal data and for calculating two related measures of vocal accommodation.

Across multiple studies, vocal accommodation significantly predicts observers’ perceptions regarding interactants engaged in debates and interviews. Studies have specifically linked vocal accommodation to perceptions of relative power or dominance, but have not shown a relationship between accommodation and perceptions of prestige.

Vocal accommodation measures have clear applications for measuring and modeling group dynamics. More work is needed to understand how accommodation functions in clearly-defined status situations, how the magnitude of status differences affects the degree of accommodation inequality, and how vocal accommodation is related to other correlates of social status, including openness to influence and contributions to group tasks.

The journey of novelty – from the moment it arises to the time it takes hold – is as fascinating as it is problematic. A new entity, to be recognized as such, needs to be differentiated from what existed before. However, novelty poses cognitive challenges that hamper its appreciation since it is difficult to form expectations about and make sense of something genuinely new. And since novel ideas, products, technologies, or organizational forms often violate existing practices and social structures, they are usually met with skepticism and resistance. In this introductory piece, we take stock of research into the challenges of generating, recognizing, and legitimating novelty. We review each paper in this volume and highlight the new perspectives and insights they offer about how individuals, teams, and organizations search for novelty, see novelty, and sustain novelty. Finally, we outline several research themes that, we believe, are worthy of further scholarly attention.

This chapter focuses on whether perceived emotional intensity and help need is possible to discriminate in expressions of fear and neutrality in brief authentic emergency calls. Extraction of acoustic parameters of fear and neutrality was done prior to letting participants listen to a low-pass-filtered stimuli set. Participants discriminated fear and neutrality in both the intensity and help need condition. In turn, judged intensity and judged help need correlated strongly, with partial correlations indicating that participants use acoustically measured intensity (mean dB) as information to infer the intensity/help need relationship. We also discuss the implications of emotional expression in the call centre domain.

This chapter explores the role of messages in knowledge networks. Messages are characterized in terms of the type of knowledge they represent and their attributes. Messages represent knowledge transactions in a network. The authors describe the type of message in terms of the knowledge capital it contains. The chapter considers what is involved in making all forms of knowledge capital available, accessible, and consumable in a network. Making knowledge available involves articulation – semantic, linguistic, visual, acoustic, and kinesthetic. Making knowledge accessible means encoding the knowledge, formatting, and packaging it as a message. The chapter also addresses factors that influence knowledge consumption, including coherence, completeness, verifiability, usefulness, relevance, orientation, freshness, and redundancy. The authors also provide examples of messaging human, structural, and relational capital.
