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
Post-carboniferous tectonics in the Anadarko Basin, Oklahoma: Evidence from side-looking radar imagery
The Anadarko Basin of western Oklahoma is a WNW-ESE elongated trough filled with of Paleozoic sediments. Most models call for tectonic activity to end in Pennsylvanian times. NASA Shuttle Imaging Radar revealed a distinctive and very straight lineament set extending virtually the entire length of the Anadarko Basin. The lineaments cut across the relatively flat-lying Permian units exposed at the surface. The character of these lineaments is seen most obviously as a tonal variation. Major streams, including the Washita and Little Washita rivers, appear to be controlled by the location of the lineaments. Subsurface data indicate the lineaments may be the updip expression of a buried major fault system, the Mountain View fault. Two principal conclusions arise from this analysis: (1) the complex Mountain View Fault system appears to extend southeast to join the Reagan, Sulphur, and/or Mill Creek faults of the Arbuckle Mountains, and (2) this fault system has been reactivated in Permian or younger times

A PI3K-mediated negative feedback regulates Drosophila motor neuron excitability
Negative feedback can act as a homeostatic mechanism to maintain neuronal activity at a particular specified value. At the Drosophila neuromuscular junction, a mutation in the type II metabotropic glutamate receptor gene (mGluRA) increased motor neuron excitability by disrupting an autocrine, glutamate-mediated negative feedback. We show that mGluRA mutations increase neuronal excitability by preventing PI3 kinase (PI3K) activation and consequently hyperactivating the transcription factor Foxo. Furthermore, glutamate application increases levels of phospho-Akt, a product of PI3K signaling, within motor nerve terminals in an mGluRA-dependent manner. In humans, PI3K and type II mGluRs are implicated in epilepsy, neurofibromatosis, autism, schizophrenia and other neurological disorders; however, neither the link between type II mGluRs and PI3K, nor the role of Foxo in the control of neuronal excitability, had been previously reported. Our work suggests that some of the deficits in these neurological disorders might result from disruption of glutamate-mediated homeostasis of neuronal excitability

Not Just a Theory—The Utility of Mathematical Models in Evolutionary Biology
Models have made numerous contributions to evolutionary biology, but misunderstandings persist regarding their purpose. By formally testing the logic of verbal hypotheses, proof-of-concept models clarify thinking, uncover hidden assumptions, and spur new directions of study. thumbnail image credit: modified from the Biodiversity Heritage Librar
The Role of (Delta)C-13 in the Search for Reduced Organics on the Surface of Mars
The capabilities of the Sample Analysis at Mars (SAM) instrument suite on the Mars Science Laboratory (MSL) to detect trace amounts of organic carbon compounds are unprecedented, and MSL may be the first mission to reveal the presence of organic carbon on Mars. The search for reduced organic carbon on Mars is inextricably tied to: a) the preservation potential of the environment from which we take a solid sample, and b) the evolved gas analysis (EGA) techniques used by SAM to release volatiles from this solid sample. Several prospective targets have been identified for sample analysis at Gale Crater. Stratigraphic sequences of phyllosilicates and sulfates at Gale are thought to represent a period of global climate transition from a moderate pH lacustrine environment to an evaporitic environment, both of which could sequester organic carbon (Thomson et al. 2011). The sediment mound in Gale Crater contains a range of lithologies suggesting changes in redox conditions, and evidence of both lacustrine and fluvial depositional processes, which may have transported organic carbon from the layer in which it formed and resulted in its preservation elsewhere within the crater (Anderson and Bell, 2010). Inverted channel fills suggest erosion resistant material that could serve to preserve organics originally deposited in a low energy aqueous environment. The lithology sampled will affect not only the preservation of organics, but also our ability to detect organics during our evolved gas analysis, based on the sample matrix. For example, reduced organics may be trapped in the mineral structure, and thermal evolution of these organics will occur during thermal decomposition of the host mineral. If organics are occluded in minerals that have very high thermal decomposition temperatures, they may be, in effect, "too well preserved," and difficult to detect during EGA. Alternatively, the possible presence of perchlorate, or other strong oxidants in surface regolith, may result in destruction of structural information identifying organic molecules before reaching the QMS on SAM via oxidation to C02 during heating. If this is the case, the stable carbon isotopic composition (delta 13C) of the C02 evolved and measured by the Tunable Laser Spectrometer (TLS) on SAM may help identify the presence of organics. On Earth, biological activity can cause large fractionations of 13C/12C, which can preserved in sedimentary deposits and distinguish the organic products of biotic processes from inorganic atmospheric and geological reservoirs. It is plausible that similar fractionations could occur on Mars and be preserved in reduced organic matter in sediments. Bulk delta 13C measurements alone may not reveal a signature of trace organic carbon that may be present along with inorganic carbon. If both organic and inorganic carbon compounds are present, it may be possible to detect the organic carbon by comparing the 013C of pyrolysis and combustion experiments. The TLS on SAM is capable of obtaining high precision measurements of delta13C from C02 evolved during pyrolysis and combustion of solid regolith samples. Because carbonates are expected to be present at abundances of 0.1-1 % in Martian soil, and organics in the ppb range (Webster and Mahaffy, 2011), analog samples must represent this mix of reduced organic carbon and carbonate. The work presented here will examine the use of delta13C of C02 produced during combustion of bulk Mars analog samples as a proxy for detection of reduced organic carbon
