Knowledge Creation as a Square Dance on the Hilbert Cube

This paper presents a micro-model of knowledge creation and transfer in a small group of people. Our model incorporates two key aspects of the cooperative process of knowledge creation: (i) heterogeneity of people in their state of knowledge is essential for successful cooperation in the joint creation of new ideas, while (ii) the very process of cooperative knowledge creation a¤ects the heterogeneity of people through the accumulation of knowledge in common. The model features myopic agents in a pure externality model of interaction. In the two person case, we show that the equilibrium process tends to result in the accumulation of too much knowledge in common compared to the most productive state. Unlike the two-person case, in the four person case we show that the equilibrium process of knowledge creation may converge to the most productive state. Equilibrium paths are found analytically, and they are a discontinuous function of initial heterogeneity.

The Perceived Effects of Dance for Individuals with Parkinson’s Disease and Healthy Amateurs

The objective of the present study was to compare the effects of dance participation on physical and psychological functioning as perceived by two distinct groups of dancers: dancers with Parkinson's disease (PD) and healthy amateur (HA) dancers. Dancers in the Parkinson's sample group were gathered from participants in the Dance for PD® program, while healthy amateur dancers were recruited from university dance departments and through social media. Both groups were administered measures related to affect, self-efficacy, quality of life, and which aspects of dance classes were most helpful and/or challenging. Several open-ended questions for both groups were included, along with questions specific to each group. Results of the study indicated that there was no difference between the two groups on positive affect experienced while dancing, but that HA dancers experienced higher levels of negative affect than PD dancers. HA dancers exhibited higher levels of self-efficacy, but there was no difference between the groups on perceived quality of life. Additionally, both groups identified the same two components of dance classes as the most helpful: "moving and getting some exercise" and "doing something fun." Thematic analysis of responses to open-ended questions found that, in general, HA and PD dancers identified similar factors which made dance unique from other forms of exercise. The primary differences were that HA dancers more strongly emphasized artistic and spiritual components of dance, whereas PD dancers focused on the importance of the dance instructors and tailoring movements to individuals with PD. More differences were found between the two groups with respect to the negative aspects of dance classes. Notably, PD dancers identified almost no negative aspects, while HA dancers described internal and external pressure, criticism, and competition as problematic. Future research could benefit from ensuring that both groups are administered the same standardized measures to allow for additional comparisons between groups and with normative samples.

The Vetlatori Dance: "Little Angels go to Heaven"

This paper discusses the vetlatori dance performed on the occasion of a baptised infant's death in the Valencia region of Spain until about fifty years ago. Analyses of historical sources that emphasise the noble spirituality of the vetlatori dance are shown to be based on romantic views of traditional culture and emotions related to the loss of an infant, rather than on authentic information. Ethnographic and ethnomusicological data are presented to illustrate that the music and dances performed during the vetlatori dance were meant for entertainment rather than for spiritual impact. Recourse is also had to oral sources, particularly interviews carried out in the 1960s and 1980s with former infant wake participants who experienced the vetlatori dance, and who confirmed the popular nature of the music, song, and dances that were performed. Analysis of written sources and of the choreographic and musical characteristics of the dance also shows that the kind of music performed was typical of festive celebration in the Valencia region. Functional outcomes for such wakes are also proposed.
