This chapter integrates agency research with an institutional perspective and investigates multiple agency conflicts in venture capital (VC) syndicates and their effect on stock-market performance of initial public offerings (IPOs) in the United States and the United Kingdom. Using a matched sample of 402 IPOs, the authors show that the size and diversity of a VC syndicate have a negative impact on performance, but this impact is higher in the United States. Ownership concentration within a syndicate improves performance, but this effect is stronger in the United Kingdom. Results indicate that the extent of multiple agency conflicts and their potential remedies are not universal and depend on formal and informal institutions.

The chapter starts with the discussion of the aesthetic category of “humorous music,” which emerged in the last decade of the eighteenth century, and links it to the theory of multiple agency, proposed by Edward Klorman (2016). There follow two case studies of hypermetric manipulations in the first movements of Haydn’s string quartets Op. 50 No. 3 and Op. 64 No. 1. These analyses reveal how such manipulations act in concert with ingenious deployment of musical topics and contrapuntal-harmonic schemata, and how they affect musical form. The chapter closes with remarks about the role of the first violinist in Haydn’s string quartets.

In field biology, interactions between wildlife and in situ equipment occur often. These interactions have the potential to induce a variety of behaviours in local fauna. Here, we note the destructive behaviour exhibited by the Muskrat (Ondatra zibethicus) following deployment of aquatic invertebrate traps for research purposes at 12 wetlands located in central Saskatchewan. Of 24 aquatic insect emergence traps used on seven wetlands in our study, 14 (58%) required recurring repairs. In addition, on several occasions, leaf litter bags and their anchoring stakes were torn or chewed. The recurring damage took place in wetlands with Muskrat lodges. We recommend structural modifications to aquatic invertebrate traps in wetland complexes densely inhabited by Muskrats and other semi-aquatic rodents.
