Exploring musician-educators’ reflections on a collaborative cross-cultural music making encounter in Singapore

Professional musician-educators from a tertiary arts institution in Singapore collaborated on a cross-cultural performance in Beijing as part of their professional development. Through a case study, semi-structured interviews explored the music making experiences of four of the musician-educators involved: the composer, the singer, the pianist and the erhu performer. Their experiences address the concept of cross-cultural music making and its significance in professional development for musician-educators. The experiences shared by the four musician-educators illuminate challenges, tensions and some areas to further resolve and critically question regarding how cultures are engaged in the process of music-making. Through unpacking the narratives of musician-educators and how they experience interactions with culture in music making, there is the possibility to further understand diverse music making encounters in Singapore.

Institutional isomorphism in collaborative, cross-cultural, project-based development work: an inquiry into the knowledge sharing behaviour of volunteers

Purpose Using an institutionalist lens, this study aims to identify factors that influence the knowledge sharing behaviour of volunteers engaged in collaborative, cross-cultural and project-focussed development work. Design/methodology/approach Following an inductive research design, the authors conducted a thematic analysis of interviews with volunteers to explore the practicalities of knowledge sharing in the context of development aid projects and to examine contributing factors, such as personality, motivations, experience and variations in team members’ understanding of the nature and objective of projects. Findings Through exploring the experiences of volunteers working on cross-cultural development aid programmes, the authors identify and discuss the ways in which the preparation of volunteers and the structuring of project work is shaped by managerialist modes of thinking, with an emphasis on the creation of an environment that is conducive to sustainable knowledge sharing practices for all stakeholders involved. Originality/value The examination of volunteer development work tendency towards institutional isomorphism is a novel contribution intersecting the areas of knowledge sharing in the project, volunteer-led and culturally diverse environments.

Patterns and Mechanisms of Sex Ratio Distortion in the Collaborative Cross Mouse Mapping Population

In species with single-locus, chromosome-based mechanisms of sex determination, the laws of segregation predict an equal ratio of females to males at birth. Here, we show that departures from this Mendelian expectation are commonplace in the 8-way recombinant inbred Collaborative Cross (CC) mouse population. More than one-third of CC strains exhibit significant sex ratio distortion (SRD) at wean, with twice as many male-biased than female-biased strains. We show that these pervasive sex biases persist across multiple breeding environments, are stable over time, and are not mediated by random maternal effects. SRD exhibits a heritable component, but QTL mapping analyses fail to nominate any large effect loci. These findings, combined with the reported absence of sex ratio biases in the CC founder strains, suggest that SRD manifests from multilocus combinations of alleles only uncovered in recombined CC genomes. We explore several potential complex genetic mechanisms for SRD, including allelic interactions leading to sex-biased lethality, genetic sex reversal, chromosome drive mediated by sex-linked selfish elements, and incompatibilities between specific maternal and paternal genotypes. We show that no one mechanism offers a singular explanation for this population-wide SRD. Instead, our data present preliminary evidence for the action of distinct mechanisms of SRD at play in different strains. Taken together, our work exposes the pervasiveness of SRD in the CC population and nominates the CC as a powerful resource for investigating diverse genetic causes of biased sex chromosome transmission.
