The pitch dependency of timbres has not been fully exploited in musical instrument identification. In this paper, we present a method using an F0-dependent multivariate normal distribution of which mean is represented by a function of fundamental frequency (F0). This F0-dependent mean function represents the pitch dependency of each feature, while the F0-normalized covariance represents the non...

Norway has a strong and diverse traditional music scene. It encompasses everything from polka-playing accordion bands in the countryside to highly sophisticated professional musicians collaborating with first class international artists from other music genres. The number of individuals playing, singing and dancing at an impressive level of proficiency is very promising. There are local clubs o...

Since the beginning of Duke Ellington’s career as composer and leader of his own jazz orchestra in the 1920s, a common critical theme has been the comparison with European art music composers such as Delius and Debussy. Assertions such as Constant Lambert’s 1934 statement that Duke Ellington set a “standard by which we may judge . . . highbrow composers” focused on the complex compositional dev...

Some environments or tasks may require multiple agents to work together to survive or thrive. Turn-based combat, found in many popular role-playing games, is one such environment. This paper examines a method to expose agents controlled by neural networks to both the solo and group cases in this domain, as well as difficulties presented by the transition from solo to group combat. The results s...

This study aims to answer the following research question: compared to solo programming, is pair programming a more cost effective method for developing software? This paper proposes a research model based on theories and previous empirical studies. It discusses a multi-study approach to address the question in hand. The first study is a survey of practitioners in regards to their experience an...

This paper presents findings from our empirical study of the creative process of improvisation, which has rarely been the subject of research in cognitive science. In this study, battle scenes in street dance were selected as an example of improvised performances. We conducted an experiment to investigate real-time cognitive processes. The results indicated three features: 1) Dancers mainly use...

The paper presents a method for segmentation and labeling of ethnomusicological field recordings. Field recordings are integral documents of folk music performances and typically contain interviews with performers intertwined with actual performances. As these are live recordings of amateur folk musicians, they may contain interruptions, false starts, environmental noises or other interfering f...

A central issue in the economics of the firm is the effect of organizational form. I use data on oil and gas drilling in the Gulf of Mexico to measure how a corporate alliance – a group of firms that develops an offshore tract as joint owners – performs relative to a solo firm. To address the endogenous matching of investment projects and organizational forms, I employ a regression discontinuit...

We examine twenty years of direct private equity investments by seven large institutions. These direct investments perform better than public market indices, especially buyout investments and those made in the 1990s. Outperformance by the direct investments, however, relative to the corresponding private equity fund benchmarks is limited and concentrated among buyout transactions. Co-investment...
