Culture and Urban Revitalization: A Harvest Document

Advocates have long argued that the economic benefits of the arts and culture provide a firm rationale for public support. Recent scholarship on the "creative class" and "creative economy" is simply the latest effort to link cultural expression to community prosperity. In contrast, the social benefits of cultural engagement have received relatively little attention, even though -- as we shall see -- they provide a stronger case.We need to avoid a simplistic either-or choice between the economic and social impacts of the arts. People who live in our cities, suburbs, and countryside are simultaneously consumers, workers, residents, citizens, and participants. Culture's role in promoting community capacity and civic engagement is central to its potential for generating vital cultural districts. To separate the economic and the social impacts of the arts makes each more difficult to understand.This document provides an overview of the state-of-the-art literature on culture and urban revitalization. In Part 2, we place the creative sector in contemporary context with a discussion of three social dynamics. The "new urban reality" has restructured our cities by increasing social diversity -- fueled by new residential patterns, the emergence of young adult districts, and immigration; expanding economic inequality; and changing urban form. Shifts in the economic and political environment have changed the structure of the creative sector. Finally, the changing balance of government, nonprofit, and for-profit institutions in social policy development -- the shift to transactional policymaking -- has profound implications for cultural policy and the creative sector broadly defined. These three forces -- the new urban reality, the changing structure of the creative sector, and the emergence of transactional policy-making -- define the context within which culture-based revitalization takes place

The Social Wellbeing of New York City's Neighborhoods: The Contribution of Culture and the Arts

This report presents the conceptual framework, data and methodology, and findings of a two-year study of culture and social wellbeing in New York City by SIAP with Reinvestment Fund. Building on their work in Philadelphia, the team gathered data from City agencies, borough arts councils, and cultural practitioners to develop a 10-dimension social wellbeing framework—which included construction of a cultural asset index—for every neighborhood in the five boroughs. The research was undertaken between 2014 and 2016.The social wellbeing tool enables a variety of analyses: the distribution of opportunity across the city;identification of areas with concentrated advantage, concentrated disadvantage, aswell as "diverse and struggling" neighborhoods with both strengths and challenges; and analysis of the relationship of"neighborhood cultural ecology" to other features of a healthy community

Efficiency of surface-driven motion: nano-swimmers beat micro-swimmers

Surface interactions provide a class of mechanisms which can be employed for propulsion of micro- and nanometer sized particles. We investigate the related efficiency of externally and self-propelled swimmers. A general scaling relation is derived showing that only swimmers whose size is comparable to, or smaller than, the interaction range can have appreciable efficiency. An upper bound for efficiency at maximum power is 1/2. Numerical calculations for the case of diffusiophoresis are found to be in good agreement with analytical expressions for the efficiency

Efficiency of autonomous soft nano-machines at maximum power

We consider nano-sized artificial or biological machines working in steady state enforced by imposing non-equilibrium concentrations of solutes or by applying external forces, torques or electric fields. For unicyclic and strongly coupled multicyclic machines, efficiency at maximum power is not bounded by the linear response value 1/2. For strong driving, it can even approach the thermodynamic limit 1. Quite generally, such machines fall in three different classes characterized, respectively, as "strong and efficient", "strong and inefficient", and "balanced". For weakly coupled multicyclic machines, efficiency at maximum power has lost any universality even in the linear response regime
