Stakeholder Governance: How Stakeholders Influence Corporate Decision Making

Abstract: Purpose – This paper aims to explore how stakeholders are voluntarily granted influence in corporate decision making. Design/methodology/approach – The stakeholder governance practices of 46 companies were explored in a multiple comparative case analysis, drawing on publicly available sources. Findings – The research finds that stakeholders are granted a voice regarding operational, managerial as well as strategic issues. The power granted to stakeholders varies from non-participation to co-decision making. The majority of engagements found are a combination of low power and low scope of participation, which are limited in their potential to align the views of those inside and outside the corporate boundaries. Research limitations/implications – The data used in this research relied on publicly available sources, such as company reports, articles and web sites. Practical implications – By seeing an array of different stakeholder governance mechanisms managers can reflect on their own approach to stakeholders and see how other companies use stakeholder engagement for scenario planning and innovation. Originality/value – The paper is the first to empirically analyse a broad range of companies regarding their voluntary stakeholder engagement mechanisms. This design allows the creation of a heuristic for stakeholder governance as well as for identifying clusters.

The LFM-1b Dataset for Music Retrieval and Recommendation

Abstract: We present the LFM-1b dataset of more than one billion music listening events created by more than 120,000 users of Last.fm. Each listening event is characterized by artist, album, and track name, and further includes a timestamp. On the (anonymous) user level, basic demographics and a selection of more elaborate user descriptors are included. The dataset is foremost intended for benchmarking in music information retrieval and recommendation. To facilitate experimentation in a straightforward manner, it also includes a precomputed user-item-playcount matrix. In addition, sample Python scripts showing how to load the data and perform efficient computations are provided. An implementation of a simple collaborative filtering recommender rounds off the code package. We discuss in detail the LFM-1b dataset's acquisition, availability, statistics, and content, and place it in the context of existing datasets. We also showcase its usage in a simple artist recommendation task, whose results are intended to serve as baseline against which more elaborate techniques can be assessed. The two unique features of the dataset in comparison to existing ones are (i) its substantial size and (ii) a wide range of additional user descriptors that reflect their music taste and consumption behavior.

Exciton-dominated optical response of ultra-narrow graphene nanoribbons

Abstract: Graphene nanoribbons exhibit an electronic bandgap and optical response that can be tuned with the ribbon width. Here, using reflectance difference spectroscopy, Denk et al. investigate the exciton-dominated optical absorption of graphene nanoribbons and its dependence on the exact atomic structure.

User-Centered Awareness in Computer-Supported Cooperative Work-Systems: Structured Embedding of Findings from Social Sciences

Abstract: An increasing number of computer-supported cooperative work (CSCW) software systems try to provide users with awareness information-information about the presence, activities, and availability of members of a community. However, most of these software systems are designed from a feature-oriented, rather than a human-oriented, point of view. In this article, a structured embedding of findings in social sciences is proposed. It reveals the variety of approaches in technology-driven CSCW developments featuring awareness, as well as the variety of empirical evidence in small-group research with respect to awareness. The authors have been looking at different aspects of awareness: the terminology used in both disciplines, the concepts that have been developed, and the different constructs that have evolved from empirical research. Finally, operational instances of awareness have been revisited. From these findings it can be concluded that awareness addresses different constellations of group settings, differen...
