Communities of practice in a community college music program: a case study examining various student expectations for music learning and participation

According to Cohen and Brawer (2008), there are four curricular functions of community colleges. Students who enroll at community colleges may seek academic transfer, vocational or technical education, developmental education, or continuing education, which includes community service. Community college faculty and administrators face a wide range of students enrolling in their courses and are challenged to stay relevant to each student. Using Wenger’s communities of practice (1998) and Lave and Wenger’s legitimate peripheral participation (1991) as a theoretical lens, I conducted a case study of a community college with similarities to my own place of employment to understand: (a) how do faculty members create and maintain appropriate communities of practice, (b) how and in what ways do the communities of practice available reflect the goals of students, and (c) what challenges do faculty members perceive in their attempt to align communities of practice with student needs. I interviewed all student music majors, all music faculty, the department chair, and the Vice-President of Academic Affairs, reviewed field notes, and analyzed pertinent documents available on the college website. I coded the data for the communities of practice concepts of mutual engagement, shared repertoire, and joint enterprise. My findings suggested that faculty members struggled to stay relevant to student expectations, a task that was exacerbated by many students who did not have expectations or who had unrealistic expectations. The diverse student body included many students that did not have career goals, academic expectations, or an understanding of the role of the community college. The case had such a small number of music majors that adding courses and programs was only possible within the structures of the current offerings and only if the cost to faculty members and the institution was minimal. Although idealistic about the potential of new programs that would attract more students, faculty members had to serve the diverse expectations of the student body inside the existing programs and courses. Implications from this research point to the importance of faculty members and administrations promoting open dialogue with one another, as well as with students, to align their goals and expectations

Degassing history of water, sulfur, and carbon in submarine lavas from Kilauea volcano, Hawaii

Major, minor, and dissolved volatile element concentrations were measured in tholeiitic glasses from the submarine portion (Puna Ridge) of the east rift zone of Kilauea Volcano, Hawaii. Dissolved H_(2)O and S concentrations display a wide range relative to nonvolatile incompatible elements at all depths. This range cannot be readily explained by fractional crystallization, degassing of H20 and S during eruption on the seafloor, or source region heterogeneities. Dissolved C0_2 concentrations, in contrast, show a positive correlation with eruption depth and typically agree within error with the solubility at that depth. We propose that most magmas along the Puna Ridge result from (I) mixing of a relatively volatile-rich, undegassed component with magmas that experienced low pressure (perhaps subaerial) degassing during which substantial H_(2)O, S, and C0_2 were lost, followed by (2) fractional crystallization of olivine, clinopyroxene, and plagioclase from this mixture to generate a residual liquid; and (3) further degassing, principally of C0_2 for samples erupted deeper than 1000 m, during eruption on the seafloor. The degassed end member may form at upper levels of the summit magma chamber (assuming less than lithostatic pressure gradients), during residence at shallow levels in the crust, or during sustained summit eruptions. The final phase of degassing during eruption on the seafloor occurs slowly enough to achieve melt/vapor equilibrium during exsolution of the typically CO_(2)-rich vapor phase. We predict that average Kilauean primary magmas with 16% MgO contain ~0.47 wt% H_(2)O, ~900 ppm S, and have δD values of ~-30 to -40‰. Our model predicts that submarine lavas from wholly submarine volcanoes (i.e., Loihi), for which there is no opportunity to generate the degassed end member by low pressure degassing, will be enriched in volatiles relative to those from volcanoes whose summits have breached the sea surface (i.e., Kilauea and Mauna Loa)

Applied Public Health Informatics: An eHealth Discipline Focused on Populations

The discipline of public health informatics, part of the broader eHealth field, brings methods, knowledge, and theories from computer science and information science to support population health and well-being. This branch of informatics is most often found in governmental public health agencies that focus on population-level activities, including surveillance of disease as well as disease prevention. There are several specialised public health information systems used to prevent or mitigate disease, including syndromic surveillance, electronic laboratory reporting, and population health dashboards. This article defines and describes public health informatics and its role in eHealth. The article further discusses the role of public health information systems and challenges they face for the future. Strengthening public health will require greater investment in interoperability as well as analytics and the workforce. Disease outbreaks like COVID-19, Ebola, and H1N1 demonstrate the need for robust public health informatics applications and methods. Yet there is much work to be done to evolve existing tools and methods to strengthen the public health infrastructure for the next pandemic

Charities from Below?: The cases of the emergence, evolution and resourcing strategies of Philanthropic Actions in the Creative and Cultural Industries in Jamaica

Abstract The thesis addresses the lack of research and understanding of indigenous philanthropic practices emerging in the Global South. It challenges mainstream assumptions of a hierarchical philanthropic relationship between (a) corporate foundations and high net worth individuals and (b) their beneficiaries. It deploys a novel combination of Resource Based Theory, through the social bricolage framework, and perspectives on the Social and Solidarity Economy as a lens to analyse the emergence, evolution, and resourcing strategies of philanthropic activities within the Creative and Cultural Industries in Jamaica. The emergence and evolution of these activities were found to be a nuanced response to a mixture of internal personal, familial and organisational factors, and changes in the local and international landscape. They were a series of networked, reciprocal interactions that transcended sector and national boundaries, similar to the little-studied ‘grassroots philanthropy’. The research examined 27 cases of philanthropic organisations, charitable individuals and one event. The findings have implications for the sustainability of philanthropic activities in a resource-constrained, developing country setting. It also challenges the Patrician approach to addressing social problems in the global South and argues that those problems can be tackled by a creative and nuanced use of resources. The thesis introduces the concept of the Cultural Solidarity Economy to fill the conceptual void in our understanding of indigenous philanthropic practices in the global South; this has elements that can ‘re-embed’ the human element into market relationships. The thesis does this by analysing the role of culture in development and viewing the relationship between the giver and receiver as part of a broader eco-system. The concept of Cultural Solidarity Economy is applicable in resource-constrained contexts where there is a close relationship between the state, market and third sector in achieving social development outcomes, and where there is informality within the third sector
