Public Opinion and Political Vulnerability: Why Has the National Endowment for the Arts Been Such an Attractive Target?
No full textFederal government arts programs appear to deviate from the rule that legislative behavior closely follows public preferences. Between the mid-1970s and the late 1980s, despite stability in public opinion, the NEA evolved from Congress’s bipartisan darling to its controversial scapegoat. We inspect 55 items from public opinion surveys and re-analyze data from 2 state and 8 national surveys undertaken between 1975 and 1996 to resolve this puzzle. Our conclusions: (1) Arts support is not a salient issue to most voters, leaving legislators relatively unconstrained. (2) Positive responses to general questions about arts funding often mask complex, ambivalent views. (3) The core constituency for federal arts support – college graduates – is difficult to mobilize because their interest in the arts is balanced by skepticism about federal government programs. (4) Opponents of arts spending successfully built on ties to Christian conservative and Republican loyalists to mobilize the stable minorities opposed to the NEA. As a result, arts politics in the U.S. has consisted of a standoff between a committed minority of 15 to 20 percent of the public that strongly opposes federal support for the arts and a weakly committed majority of about 60 percent that favors the federal role.
Nonprofit Organizations and the Intersectoral Division of Labor in the Arts
No full textThis paper takes stock of what we know about the role of nonprofit enterprise in the production and distribution of the arts (broadly defined), primarily in the United States. After briefly discussing measurement, I present data on the extent of nonprofit activity in a range of cultural subfields. I then review theoretical explanations of the prevalence of nonprofits in cultural industries and discuss some puzzles that existing theories do not adequately solve. After reviewing research and theory about behavioral differences between nonprofit and for-profit arts firms, I explore how the art-and-culture sector is evolving in the face of demographic change, the weakening of the cultural hierarchy, and the emergence of new production and distribution technologies. I conclude with a research agenda.
Note: Improvement of the 3w thermal conductivity measurement technique for its application at the nanoscale
No full textConventional techniques for thermal conductivity measurements can lead to unreliable results when applied to nanostructures because heaters and temperature sensors needed for the measurement cannot have a negligible size and therefore perturb the result. In this paper, we focus on the 3w technique, applied to the evaluation of the thermal conductivity of suspended silicon nanoribbons. We introduce a numerical approach based on the finite element solution of the electrical and thermal transport equations and compare its results with those of conventional methods. We show that with our approach we achieve an excellent fit of the experimental data, in particular, for nanostructured materials
Thermal Conductivity Reduction in Rough Silicon Nanomembranes
No full textNanostructured silicon is a promising material for thermoelectric conversion because the thermal conductivity in silicon nanostructures can be strongly reduced with respect to that of bulk materials. We present thermal conductivity measurements, performed with the 3ω technique, of suspended monocrystalline silicon thin films (nanomembranes or nanoribbons) with smooth and rough surfaces. We find evidence for a significant effect of surface roughness on phonon propagation: the measured thermal conductivity for the rough structures is well below that predicted by theoretical models which take into account diffusive scattering on the nanostructure walls. Conversely, the electrical conductivity appears to be substantially unaffected by surface roughness: the measured resistance of smooth and rough nanostructures is comparable, if we take into account the geometrical factors. Nanomembranes are more easily integrable in large area devices with respect to nanowires and are mechanically stronger and able to handle much larger electrical currents, thus enabling the fabrication of thermoelectric devices that can supply higher power levels with respect to existing solutions. © 2002-2012 IEEE
Information Inequality and Network Externalities: A Comparative Study of the Diffusion of Television and the Internet
No full textThis paper sheds light on whether intergroup inequality in Internet access is likely to persist as the diffusion process continues. To what extent is a given level of inequality in technology diffusion (e.g., use of the Internet) a long-term policy challenge or a temporary inconvenience? What general factors account for group-specific patterns of technology adoption? This paper draws on notions of network externalities to help answer this question. It also presents findings from a comparative analysis of household adoption of television from 1948 to 1957 and the Internet from 1994 to 2002.
Organizzare la cultura. Imprenditoria, istituzioni e beni culturali
No full textFinissimo conoscitore di processi e istituzioni culturali, Paul DiMaggio nei contributi raccolti in questo volume approfondisce un tema affascinante: come la produzione di una gerarchia culturale abbia bisogno di un sapiente utilizzo di rituali e contrassegni, destinati a regolare le relazioni tra pubblico e opera d'arte. Così viene istituito, o addirittura sacralizzato, il confine tra cultura "alta" e cultura "popolare"; così la produzione culturale si fa oggetto di imprenditorialità e management; così certi tipi di cultura diventano, in determinati luoghi ed epoche, un preziosissimo capitale, socialmente spendibile. In questa illuminante prospettiva sono qui analizzati i confini socioculturali connessi al teatro, all'opera o alla danza; la nascita di una grande orchestra sinfonica o di un prestigioso museo; la classificazione gerarchica dei generi artistici e le sue sorprendenti trasformazioni.
