Silicon Valley Community Foundation: 10 Years of Innovation and Impact
Over the past 10 years, Silicon Valley Community Foundation has grown to become the world's largest community foundation, engaging, empowering, and collaborating with family, individual, and corporate donors to generate positive impact by supporting organizations within and beyond county lines and national borders. SVCF has also become a comprehensive center for philanthropy, engaging as advocates in pursuit of tackling critical public policy issues, partnering with nonprofit groups and institutions who aim to advance ideas and direct resources strategically toward pressing, critical needs, commissioning research to identify emerging issues and anticipate future needs, and launching strategic initiatives in support of the local community.A combination of stories and data will illustrate how Silicon Valley Community Foundation harnessed a local culture of innovation to become a leader of the field, expanded its reach across the entire globe, and continues to find new ways to generate positive impact
2015 Columbus Survey Findings
"2015 Columbus Survey Findings" presents a snapshot of data on community foundation growth and related operational activity during fiscal year 2015. These findings are based on Columbus Survey responses from 271 community foundations, accounting for over 90 percent of the field's estimated assets. Results from the Survey show a slowdown in asset growth after several years of rapid field expansion, though positive trends in grantmaking, as well as in operating efficiency, are also seen. These findings and more are unpacked and illustrated in this report on the state of the community foundation field
Assessing Community Foundation Needs and Envisioning the Future
Community foundations have several attributes that, taken together, distinguish them from many of their philanthropic brethren, including a local orientation, relationships with many living donors, and a public charity tax status. This affects everything from their approach to solving problems to their business model. Because of this, community foundations have sought out support services that are designed for their particular needs. The infrastructure of organizations serving community foundations has evolved, and there has been confusion among community foundations over where to get their needs met and some frustration over the perceived fragmentation of services.In response to these concerns and to create some clarity, CFLeads and CF Insights, both of which exclusively serve community foundations, decided to map out the current support services and lead a discussion exploring a vision for the future. The findings from a survey of a dozen large community foundations and a one-day symposium are summarized here. Hopefully the results of this partnership provide a better understanding of the ecosystem of organizations serving community foundations and some initial thinking on how to meet needs in the future
International Giving by U.S. Community Foundations: Local Communities with Global Reach
This report, a joint effort by the Council on Foundations and Foundation Center, examines the current state and recent trends in international giving and engagement by large U.S. community foundations. The first-ever analysis of this type suggests that many community foundations are beginning to adopt a broader, more nuanced definition of "community" than they have in the past.The report documents how funds channeled from U.S. community foundations support international programs and recipients and highlights five U.S. community foundations and their approaches to global engagement and international grantmaking. For this report, we analyzed all the international grants made by U.S. community foundations included in Foundation Center's set of 1,000 of the largest U.S. Foundations from 2011 to 2014, which included 10,533 grants worth $697 million
Retarded photooxidation of cyamemazine in biomimetic microenvironments
Cyamemazine (CMZ) is a neuroleptic drug that mediates cutaneous phototoxicity in humans. Here, the photobehavior of CMZ has been examined within (1)-acid glycoproteins, - and -cyclodextrins and SDS micelles. In all these microenvironments, CMZ emission was enhanced and blue-shifted, and its lifetime was longer. Irradiation of the entrapped drug at 355nm, under air; led to the N,S-dioxide. Within glycoproteins or SDS micelles the reaction was clearly slower than in phosphate buffered solution (PBS); protection by cyclodextrins was less marked. Transient absorption spectroscopy in PBS revealed formation of the triplet state ((3)CMZ*) and the radical cation (CMZ(+center dot)). Upon addition of glycoprotein, the contribution of CMZ(+center dot) became negligible, whereas (3)CMZ* dominated the spectra; in addition, the triplet lifetime became considerably longer. In cyclodextrins, this occurred to a lower extent. In all microheterogeneous systems, quenching by oxygen was slower than in solution; this was most remarkable inside glycoproteins. The highest protection from photooxidation was achieved inside SDS micelles. The results are consistent with photooxidation of CMZ through photoionization and subsequent trapping of the resulting radical cation by oxygen. This reaction is extremely sensitive to the medium and constitutes an appropriate probe for localization of the drug within a variety of biological compartments.Financial support from the Spanish Government (CTQ2010-14882, BES-2011-043706, JCI-2010-06204) and from the Generalitat Valenciana (PROMETEOII/2013/005) is gratefully acknowledged.Limones Herrero, D.; PĂ©rez Ruiz, R.; JimĂ©nez Molero, MC.; Miranda Alonso, MĂ.

Down but not out in posterior cingulate cortex : Deactivation yet functional coupling with prefrontal cortex during demanding semantic cognition
The posterior cingulate cortex (pCC) often deactivates during complex tasks, and at rest is often only weakly correlated with regions that play a general role in the control of cognition. These observations led to the hypothesis that pCC contributes to automatic aspects of memory retrieval and cognition. Recent work, however, has suggested that the pCC may support both automatic and controlled forms of memory processing and may do so by changing its communication with regions that are important in the control of cognition across multiple domains. The current study examined these alternative views by characterising the functional coupling of the pCC in easy semantic decisions (based on strong global associations) and in harder semantic tasks (matching words on the basis of specific non-dominant features). Increasingly difficult semantic decisions led to the expected pattern of deactivation in the pCC; however, psychophysiological interaction analysis revealed that, under these conditions, the pCC exhibited greater connectivity with dorsolateral prefrontal cortex (PFC), relative to both easier semantic decisions and to a period of rest. In a second experiment using different participants, we found that functional coupling at rest between the pCC and the same region of dorsolateral PFC was stronger for participants who were more efficient at semantic tasks when assessed in a subsequent laboratory session. Thus, although overall levels of activity in the pCC are reduced during external tasks, this region may show greater coupling with executive control regions when information is retrieved from memory in a goal-directed manner
Exclusive rho^0 muoproduction on transversely polarised protons and deuterons
The transverse target spin azimuthal asymmetry A_UT in hard exclusive
production of rho^0 mesons was measured at COMPASS by scattering 160 GeV/c
muons off transversely polarised protons and deuterons. The measured asymmetry
is sensitive to the nucleon helicity-flip generalised parton distributions E^q,
which are related to the orbital angular momentum of quarks in the nucleon. The
Q^2, x_B and p_t^2 dependence of A_UT is presented in a wide kinematic range.
Results for deuterons are obtained for the first time. The measured asymmetry
is small in the whole kinematic range for both protons and deuterons, which is
consistent with the theoretical interpretation that contributions from GPDs E^u
and E^d approximately cancel.Comment: 20 pages, 9 figures and 4 tables, updated author lis

Spatial planning for a green economy: National-level hydrologic ecosystem services priority areas for Gabon
<div><p>Rapidly developing countries contain both the bulk of intact natural areas and biodiversity, and the greatest untapped natural resource stocks, placing them at the forefront of âgreenâ economic development opportunities. However, most lack scientific tools to create development plans that account for biodiversity and ecosystem services, diminishing the real potential to be sustainable. Existing methods focus on biodiversity and carbon priority areas across large geographies (e.g., countries, states/provinces), leaving out essential services associated with water supplies, among others. These hydrologic ecosystem services (HES) are especially absent from methods applied at large geographies and in data-limited contexts. Here, we present a novel, spatially explicit, and relatively simple methodology to identify countrywide HES priority areas. We applied our methodology to the Gabonese Republic, a country undergoing a major economic transformation under a governmental commitment to balance conservation and development goals. We present the first national-scale maps of HES priority areas across Gabon for erosion control, nutrient retention, and groundwater recharge. Priority sub-watersheds covered 44% of the countryâs extent. Only 3% of the country was identified as a priority area for all HES simultaneously, highlighting the need to conserve different areas for each different hydrologic service. While spatial tradeoffs occur amongst HES, we identified synergies with two other conservation values, given that 66% of HES priority areas intersect regions of above average area-weighted (by sub-watersheds) total forest carbon stocks and 38% intersect with terrestrial national parks. Considering implications for development, we identified HES priority areas overlapping current or proposed major roads, forestry concessions, and active mining concessions, highlighting the need for proactive planning for avoidance areas and compensatory offsets to mitigate potential conflicts. Collectively, our results provide insight into strategies to protect HES as part of Gabonâs development strategy, while providing a replicable methodology for application to new scales, geographies, and policy contexts.</p></div
