Modes of communication during jazz improvisation

This study investigated modes of communication adopted by six student jazz musicians during rehearsal and performance. Six one-hour rehearsal sessions and a performance were observed and videotaped for analysis. Results revealed six modes of communication that formed two main categories, verbal and non-verbal, each containing three distinct modes of communication: instruction, cooperation and collaboration. Non-verbal collaborative mode displayed empathetic attunement, which is a vehicle for empathetic creativity. Empathetic creativity is a theoretical concept proposed by the author based on the concept of empathetic intelligence (Arnold, 2003, 2004). Practical applications of empathetic creativity are discussed with reference to music education, focusing on evaluation of individual contribution to group creative performances

The UK’s first professional symphony orchestra cooperative: social enterprise?

This conference paper reports the results of the first phase of a three phase longitudinal research study designed to examine the initiation and development of the UK‟s first professional symphony orchestra cooperative. Semi-structured interviews were conducted with thirty six professional musicians from a "pool" of forty plus musicians. This "pool" of musicians provides the cooperative with a resource that can be drawn on to form an orchestra to rehearse for and perform concerts and recordings. Preliminary results reveal four themes that emerged from the semi-structured interview data. These themes were interpreted by the researchers as: "commitment", "democracy", "social mission" and "aesthetic aspirations". The themes are presented along with supporting quotations from the interview data that illustrate the characteristics of these four emergent themes. The implications of the themes are then discussed within the context of the prior literature reviewe

Investigating an ‘institutional partnership’ collaborating to develop a funded project into a sustainable work-integration social enterprise (WISE)

This paper reports a research study that examined a partnership between a regional social enterprise development agency and a university as they collaborated to develop a work-integration social enterprise (WISE) in the UK. Participants were members of the board of directors, steering group and the programme delivery and administration staff. The research elicited participant perceptions of the development of the partnership and the WISE over a period of eighteen months. Semi-structured interviews were conducted with participants in three phases: ‘early’, ‘middle’ and ‘late’. Results revealed the problems experienced by the partnership, which ultimately inhibited the development of a sustainable WIS

Investigating the outcome performance of work-integration social enterprises (WISEs): do WISEs offer ‘added value’ to NEETs?

This study takes a comparative approach to study the ‘outcome’ performance of a WISE and a ‘for-profit’ work-integration organisation that both provided employment enhancement programmes to NEETs. Participants at both organisations completed general self-efficacy questionnaires before and after engagement on the programmes. Additionally, semi-structured interviews and focus groups were held with the owners and staff at both organisations. Results revealed no significant difference between the ‘outcome’ performance of the WISE and for-profit organisation. However, analysis of the organisational aims, values and structures suggests that the ‘added value’ offered by the WISE came from the different induction policy that it operate

What are the barriers to investing in social enterprises? An investigation into the attitudes and experiences of social entrepreneurs in the United Kingdom

The ongoing global economic crisis and the restrictions that this is having on government expenditure has meant that current UK policy is being directed at trying to end the grant dependency that currently exists in the third sector. One of the key focuses of this policy initiative has been to try to increase the third sector’s access to both debt finance from lending institutions and equity finance from venture capital investors. However, this policy intervention presupposes that the lack of private sector investment in the third sector is a ‘supply-side’ problem caused by limited funds. This ignores the structural problems in the social enterprise sector related to governance and a lack of organisational capacity. Indeed, as of 2011 the ethical investment sector in the UK was worth approximately £9 billion and was spread across 90 ethical investment funds responsible to 700,000 investors. Additionally, social investment (i.e. those funds targeted specifically at third sector organisations) was worth £165 million as of 2011. This suggests that the lack of private sector investment in social enterprises in the UK is not a ‘supply’ side problem but is instead related to the ‘investment readiness’ of social enterprise

Epidemiology and disease burden of tuberculosis in children: a global perspective

Our understanding of the tuberculosis (TB) epidemic in children is incomplete due to challenges in diagnosis and reporting. Children have also been largely excluded from research and advocacy. However, the tide appears to be turning and interest in pediatric TB is increasing. In this article, we explore the epidemiology of childhood TB by first reviewing the natural history of TB in children and the factors that impact on each of the stages from exposure to disease. We then discuss how these factors affect what we see at a country and regional level. Finally, we assess the burden of childhood TB globally. © 2014 Seddon and Shingadia

Preliminary analysis of fuel tank impact

Following the accident involving the Air France Concorde in 2000 the effects of fluid structure interactions resulting from the impact of a fluid filled tank has become a cause for concern. The work reported here relates to the design of a series of experiments loosely based upon the Concorde incident which aimed to assess whether the probable failure mode in the Concorde accident could occur in land based vessels. Preliminary numerical analyses were undertaken for two of the nine cases that were investigated experimentally in which an empty tank was impacted by a projectile with a velocity of 14m/s and 21.9m/s Initial numerical results for the acceleration at two points on the tank surface and the deformation at the impact zone showed good agreement with test data. Future work is discussed including further numerical modelling incorporating fluid structure interactions for the analysis of the cases when the tank is partially full or completely full

Asymmetric thymocyte death underlies the CD4:CD8 T-cell ratio in the adaptive immune system

It has long been recognized that the T-cell compartment has more CD4 helper than CD8 cytotoxic T cells, and this is most evident looking at T-cell development in the thymus. However, it remains unknown how thymocyte development so favors CD4 lineage development. To identify the basis of this asymmetry, we analyzed development of synchronized cohorts of thymocytes in vivo and estimated rates of thymocyte death and differentiation throughout development, inferring lineage-specific efficiencies of selection. Our analysis suggested that roughly equal numbers of cells of each lineage enter selection and found that, overall, a remarkable ∼75% of cells that start selection fail to complete the process. Importantly it revealed that class I-restricted thymocytes are specifically susceptible to apoptosis at the earliest stage of selection. The importance of differential apoptosis was confirmed by placing thymocytes under apoptotic stress, resulting in preferential death of class I-restricted thymocytes. Thus, asymmetric death during selection is the key determinant of the CD4:CD8 ratio in which T cells are generated by thymopoiesis
