    Public Engagement in the Arts: A Review of Recent Literature

    In recent years, research has found that across the US, arts audiences are declining while arts participation is on the rise. How can both be true at the same time? This literature review on Public Engagement in the Arts that explores this question. It also delves intothe different ways in which "public engagement" can be defined and practiced,the purposes public engagement has been used for in the arts, andhow the terms "audience" and "participant" have evolved and blurred over time.This literature review also places public engagement in the context of one of the most urgent conversations taking place in the arts and culture field today, that of cultural equity and inclusion. How can we ensure that everyone in our community has access to the opportunities and benefits provided by the arts? As this review discusses, public engagement is one tool available to artists, arts organizations and arts educators to help them work toward that goal

    Do all Americans have equal access to the arts? Are the arts accessible and inclusive for all communities? National rates of arts participation as measured by attendance at live benchmark events have been trending down for the past few decades. Consequently, a narrative of arts decline in the US has been largely accepted, even as some accounts show cultural engagement experiencing a renaissance enabled by advanced communication technologies and changing demographics.This report, informed by a review of practitioner and academic literature, charts the concerns of arts stakeholders surrounding public arts engagement since about 2000, beginning with the discovery of a statistically significant decline in benchmark attendance as observed in the Survey of Public Participation in the Arts (SPPA). It also traces the role of the "informal arts" (folk, traditional and avocational arts) in broadening the definition of arts and cultural participation.Authors Henry Jenkins and Vanessa Bertossi (2007) have suggested that we are living in a "new participatory culture" distinguished by four factors:1. Low barriers to artistic expression and civic engagement;2. Strong support for creating and sharing what one creates with others;3. Transmission of knowledge and skills through informal mentorship networks; and4. A degree of social currency and sense of connectedness among participantsThis new culture makes measuring arts participation more difficult because traditional distinctions between amateur and professional, hobbyist and artist, and consumer and producer are blurring. Broadening the definition of arts participation to include leisure time investment in creative pursuits and arts-making helps enlarge the definition of art's value to society (Ramirez, 2000). Expanding our sense of "what counts" initiates new conversations by reframing the old question "Why aren't people attending?" as "What are people doing with their creativity-focused leisure time?" New cultural indicators are revealing the value of arts and culture in people's everyday lives, shifting the narrative about arts participation in the early twenty-first century from decline to resurgence.Even as both the concept and measurement of "engagement" in the arts has evolved over time, the understanding of the purpose of that engagement has varied. For some organizations, engagement has meant creating new inroads to existing programming. For others, engagement has meant developing new programs to capture the attention of new audiences. In 2015, this conversation took a new direction as people moved from talking about engagement as a process to focusing instead on a key outcome: cultural equity and inclusion. In Los Angeles County, as well as across the U.S., arts organizations began to focustheir attention on ensuring that everyone has access to the benefits offered by the arts. Viewed through this lens, this literature review should be seen as a companion ‚Äď a prequel, even ‚Äď to the literature review on cultural equity and inclusion published by the Los Angeles County Arts Commission in March 2016

    Deformation and rigidity of simplicial group actions on trees

    Full text link
    We study a notion of deformation for simplicial trees with group actions (G-trees). Here G is a fixed, arbitrary group. Two G-trees are related by a deformation if there is a finite sequence of collapse and expansion moves joining them. We show that this relation on the set of G-trees has several characterizations, in terms of dynamics, coarse geometry, and length functions. Next we study the deformation space of a fixed G-tree X. We show that if X is `strongly slide-free' then it is the unique reduced tree in its deformation space. These methods allow us to extend the rigidity theorem of Bass and Lubotzky to trees that are not locally finite. This yields a unique factorization theorem for certain graphs of groups. We apply the theory to generalized Baumslag-Solitar groups and show that many have canonical decompositions. We also prove a quasi-isometric rigidity theorem for strongly slide-free G-trees.Comment: Published in Geometry and Topology at http://www.maths.warwick.ac.uk/gt/GTVol6/paper8.abs.htm

    JSJ decompositions of Quadratic Baumslag-Solitar groups

    Full text link
    Generalized Baumslag-Solitar groups are defined as fundamental groups of graphs of groups with infinite cyclic vertex and edge groups. Forester proved (in "On uniqueness of JSJ decompositions of finitely generated groups", Comment. Math. Helv. 78 (2003) pp 740-751) that in most cases the defining graphs are cyclic JSJ decompositions, in the sense of Rips and Sela. Here we extend Forester's results to graphs of groups with vertex groups that can be either infinite cyclic or quadratically hanging surface groups.Comment: 20 pages, 2 figures. Several corrections and improvements from referee's report. Imprtant changes in Definition 5.1, and the proof of Theorem 5.5 (previously 5.4). Lemma 5.4 was adde

    Analysis of the performance of the drive system and diffuser of the Langley unitary plan wind tunnel

    A broad program was initiated at the Langley Research Center in 1973 to reduce the energy consumption of the laboratory. As a part of this program, the performance characteristics of the Unitary Plan Wind Tunnel were reexamined to determine if potential methods for incresing the operating efficiencies of the tunnel could be formulated. The results of that study are summarized. The performance characteristics of the drive system components and the variable-geometry diffuser system of the tunnel are documented and analyzed. Several potential methods for reducing the energy requirements of the facility are discussed
