Finite-size effects on the thermal conductivity of ^4He near T_\lambda
We present results of a renormalization-group calculation of the thermal
conductivity of confined He in a geometry above and
at within model F with Dirichlet boundary conditions for the order
parameter. We assume a heat flow parallel to the boundaries which implies
Neumann boundary conditions for the entropy density. No adjustable parameters
other than those known from bulk theory and static finite-size theory are used.
Our theoretical results are compared with experimental data by Kahn and Ahlers.Comment: 2 pages, 2 figure
The Influence of the Legal Environment On the Development of the Nonprofit Sector
Underlying the beliefs that the evolution of the nonprofit sector in different countries can be significantly affected by the 'favoribility' or 'unfavoribility' of the legal framework within which nonprofit organisations operate. While nonprofit organisations are, to a significant extent, informal organisations, they nevertheless interact with the formal mechanisms of the law in a varity of ways. This may range from the establishment of legal personality and its resulant protection of members and officers from personal legal libility for the organisations' actions, to provisions in the tax law which encourage or discourage contributions to such organisations

Grassroots Creative Hubs: Urban Regeneration, Recovered Industrial Factories and Cultural Production in Buenos Aires and Rio de Janeiro
This chapter examines the nature, functioning and politics of grassroots creative hubs as contained in refurbished industrial factories. The renewal and transformation of factories into arts and cultural venues has been a key feature of post-industrial urbanism in the last three decades. Examples abound across the world, from railway and power stations to post office buildings and chocolate factories, these recovered infrastructures have been re-signified as cultural facilities – performing or multi-arts centres, galleries, cultural centres, creative economy laboratories, incubators and museums. These initiatives, be that they are led by local governments or community groups, are part of broader urban strategies for revitalising historical centres, revalorising cultural heritage and creating work opportunities as well as resources for tourism and business investment. But can a factory building be considered a creative hub? Does the materiality of these urban artefacts provide a solution to the oftentransient nature of ephemeral cultural urbanism?
Refurbishing old industrial factories and warehouses for cultural use and creative production has been the subject of much investigation since the 1980s-1990s, mainly through the study of culture-led urban regeneration and gentrification (Zukin, 1989; Montgomery, 1995; Evans and Shaw, 2004; Mommaas, 2004; Pratt, 2009), and more recently, creative industry clusters and districts (Evans, 2009; Zukin and Braslow, 2011; O’Connor and Gu, 2012). These studies have pointed out the problems that arise from the organisation, management and long-term sustainability of converted industrial sites, as well as from the policy uses and abuses that often pave the way to real-estate development and social displacement.
Drawing on insights from urban sociology and critical geography, the chapter conducts a case-study analysis of two cultural and creative economy factories in Latin America: Fábrica Bhering in Rio de Janeiro, Brazil, and IMPA, la Fábrica Cultural in Buenos Aires, Argentina. The chapter is comprised of three sections: the first discusses whether recovered industrial factories can be thought of as creative hubs in relation to ephemeral cultural urbanism; the second examines the two case-studies in the context of Brazil and Argentina; and the third offers concluding remarks. Overall the chapter contributes a Latin American perspective on culture-led urban regeneration to the study of creative hubs. Particularly, grassroots creative initiatives of urban renewal are presented as an alternative to the exclusionary gentrification processes to which creative hubs and other territorial forms of creativity are often related to, in times largely shaped by neoliberal operations driven by real-estate interests and alliances between political and economic urban elites

Mapping Philanthropic Foundations’ Characteristics: towards an international integrative framework of foundation types
As philanthropic foundations take on increasingly prominent sociopolitical roles, the need for stronger conceptualizations of foundations as an organizational form is articulated widely across academic, policy, and practice contexts. Building on institutional research’s tradition of categorizing, classifying and typologizing organizational forms, our article critically explores the different ways in which foundations have been cast and differentiated in international academic and practice literatures. Examining and integrating these, we propose an integrative framework of foundation types. Incorporating 13 categories—three contextual, five organizational, and five strategic ones—the framework allows for clarifying distinctions and identifying commonalities between different foundation forms, offering a basis for developing more reflective and differentiated research and practice knowledge
Heteronomy in the arts field: state funding and British arts organizations
For Bourdieu, the field of cultural production is comprised of an autonomous and a heteronomous sector. A heteronomous sector is one that is interpenetrated by the commercial field. I discuss an arena that, until recently, was part of the relatively autonomous sector in the field of cultural production—the supported arts sector in the United Kingdom—and argue that it became more heteronomous, due to the penetration by the state. Heteronomy due to the commercial field is present but secondary to, and driven by, the actions of the state. Political parties’ attempts to diffuse and legitimate a particular economic ideology have led to state demands that arts institutions adopt neoliberal business practices in exchange for funding. Government giving to the arts, previously at arms-length, proved to be a Faustian bargain that demanded significant repayment in the form of lost autonomy. Coercive pressures from the state, enacted over time, show how the domination of one field over another can occur, even when the domination is resisted
