Selection models in the music industry: How a prior independent experience may affect chart success

The is article analyses the two main approaches for artists’ selection in the recording industry: the direct model in which large major companies directly choose new artists from the supply market, and the agency model in which small independent labels realise the first choice and, subsequently, large organisations pick their new artists among those pre-selected by independents.An empirical analysis of chart sales reveals that artists selected through the agency model exhibit a longer presence on the chart due to repeated successes, while they are slower to reach heavy success once they have entered the chart. Conversely, the direct model leads to artists with a faster path to a strong success, but the same artists have a shorter presence on the chart due to the sporadic nature of their success. The profile of artists selected through these two models is also found to be different: big international soloist stars are more frequently selected through the direct model, while national bands are more frequently selected through the agency model.The insights suggest important implications for management in the cultural industries and especially in the recording industry.

Making IT work for municipalities: Building municipal wireless networks

The lack of widely available, affordable broadband Internet access has spurred a movement in which municipalities are rolling out wireless broadband networks. This movement has raised a number of questions including: Why are municipalities acting as the early adopters of wireless broadband technology? How does increased state regulation of municipal broadband networks affect this trend and how can cities respond? As cities use wireless broadband technology to enhance services to citizens, the growth of municipal wireless deployments has transitioned from linear to exponential. In response, many states have passed laws to regulate and restrict cities' ability to own, operate, deploy, or profit from either telecommunications or information services. Current and pending laws will be examined to understand how cities can deploy a wireless broadband network under these regulations. An analysis of municipal facilities and technology expertise illustrates the opportunity for public–private cooperation in wireless deployments. This paper will show that cooperation is beneficial in many cases. Finally, current business models will be examined for their ability to foster cooperation between the public and private sectors, bridge the digital divide, and create competition among private sector providers.

A comparison of two approaches for measuring interdisciplinary research output: The disciplinary diversity of authors vs the disciplinary diversity of the reference list

This study investigates the convergence of two bibliometric approaches to the measurement of interdisciplinary research: one based on analyzing disciplinary diversity in the reference list of publications, the other based on the disciplinary diversity of authors of publications. In particular we measure the variety, balance, disparity and integrated diversity index of, respectively, single-author, multi-author single-field, and multi-author multi-field publications. We find that, in general, the diversity of the reference list grows with the number of fields reflected in a paper’s authors’ list and, to a lesser extent, with the number of authors being equal the number of fields. Further, we find that when fields belonging to different disciplines are reflected in the authors’ list, the disparity in the reference list is higher than in the case of fields belonging to the same discipline. However, this general tendency varies across disciplines, and noticeable exceptions are found at individual paper level.     

Increasing engagement of students with learning disabilities in mathematical problem‐solving and discussion

Engagement in problem‐solving and mathematical discussion is critical for learning mathematics. This research review describes a gap in the literature surrounding engagement of students with Learning Disabilities in standards‐based mathematical classrooms. Taking a sociocultural view of engagement as participation in mathematical practices, this review found that students with LD were supported towards equal engagement in standards‐based mathematics through multi‐modal curriculum, consistent routines for problem‐solving, and teachers trained in Mathematical Knowledge for Teaching. Using this small set of studies (7), we identify the need to deepen the engagement of students with LD in mathematical problem‐solving and discussion. This review concludes with implications for teaching and learning.     

Anatomical societies find new ways to come together in a post-Covid world

The world has been turned upside down by a global health emergency caused by the Covid-19. Given the high contagiousness of the virus and the need to contain its spread, social distancing rules, self-isolation policies, and geographical lockdowns have been enforced globally. Over the pandemic emergency the majority of the planned in-person meetings and congresses of national and international anatomical societies have been postponed or canceled. It is unclear what the future holds, but times of crisis often present possibilities for re-thinking old ways to achieve a more critical approach. It has become increasingly clear that traditional in-person congress formats of scientific societies need to be reevaluated. Over the past year and a half, two types of congressional modalities have been trialed to address the challenge of the pandemic as far as scientific meetings are concerned: the fully virtual congress, in which case the conference program is live streamed to all of the attendees, and the hybrid congress, in which case some of the attendees physically participate at the congress's venue while others interact via a virtual platform. The current study set out to investigate the technical difficulties, social challenges, costs and sustainability, logistics and management issues linked to holding various types of congresses in the post-Covid world. Anatomical societies throughout the world are actively striving to reshape their response to the current global emergency and to uncover new types of conference modalities in the effort to keep scientific exchange alive and flourishing in the post-Covid era.
