The Impact of Social Information on the Voluntary Provision of Public Goods: A Replication Study

Shang and Croson (2009) found that providing information about the donation decisions of others can have a positive impact on individual donations to public radio. In this study, we attempted to replicate their results, however, we found no evidence of that social comparisons affected donation decisions. Most of our donors were renewing members, a group which Shang and Croson also found were not influenced by social information

Global network of computational biology communities: ISCB's regional student groups breaking barriers [version 1; peer review: Not peer reviewed]

Regional Student Groups (RSGs) of the International Society for Computational Biology Student Council (ISCB-SC) have been instrumental to connect computational biologists globally and to create more awareness about bioinformatics education. This article highlights the initiatives carried out by the RSGs both nationally and internationally to strengthen the present and future of the bioinformatics community. Moreover, we discuss the future directions the organization will take and the challenges to advance further in the ISCB-SC main mission: “Nurture the new generation of computational biologists”.Fil: Shome, Sayane.

Survey of Utility-Scale Wind and Solar Developers Report

In 2023, Berkeley Lab conducted the first of its kind survey of industry professionals with direct experience working in community engagement and permitting of land-based, utility-scale wind and solar energy facilities in the U.S. The survey solicited information about project timelines over the last five years, leading causes of project delays and cancelations, community opposition, experience with permitting authorities, community engagement, comparisons between wind and solar, and other related topics. A total of 123 individuals responded to the survey for a response rate of 19.2%. Respondents were employed at 62 unique companies, which together are responsible for approximately half of the wind and solar developed from 2016 to 2023

Community Centered Solar Development (CCSD) Study Interviews

Large-scale solar (LSS, defined here as ground-mounted photovoltaic projects ≥1 MWDC) has grown rapidly in the U.S., accounting for nearly half of new electric generating capacity added to the U.S. grid in 2022. All sources of electricity bring positive and negative impacts to hosting communities and the rapid growth of LSS has increased the urgency to understand those impacts. Yet, information about the potential positive and negative impacts of LSS on host communities, and the factors or drivers leading to support or opposition to a project, is lacking. This information gap limits how project developers, municipalities, and local siting authorities can address community concerns and appropriately align proposed projects to best suit and benefit local communities. As part of Berkeley Lab’s Community-Centered Solar Development (CCSD) project, this research set out to explore deep insights and perceptions from LSS stakeholders that only qualitative data can provide to identify key factors driving project success or threatened failure. Case studies, such as those utilized in this research, are uniquely adept at capturing the subjective experience of individuals and at identifying variables, structures, and interactions between stakeholders. Our case studies included 54 semi-structured interviews across 7 different LSS sites, representing a diversity of geographies, project sizes (MW), site types (i.e., greenfield, agrivoltaic, and brownfield / contaminated sites), zoning jurisdiction types, and more (Table 1). In addition to local residents living in close proximity to these LSS sites, we interviewed other key stakeholders involved in the projects such as developers, decision-makers, utility representatives, landowners, and individuals from community-based organizations. The overarching aim of this case study research was two-fold: (1) to inform subsequent tasks in the CCSD research project (including an upcoming national survey of LSS neighbors), and (2) to provide insights into the following set of research questions: -What are the key positive and negative drivers leading to support and opposition to LSS projects? -To what extent do LSS projects exacerbate or mitigate perceived inequities and marginalization within hosting communities and how can those inequities be mitigated going forward? -What strategies can communities employ to align LSS development with local land-use plans and community needs and values? The research findings and next steps are described in this slide deck report

Perceptions of Large-Scale Solar Project Neighbors: Results From a National Survey

Driven by favorable economics, policy factors, and decarbonization goals, large-scale solar (LSS, defined here as ground-mounted photovoltaic projects ≥1 MWDC) has expanded rapidly in recent years, with more than 90 gigawatts (GW) now installed across the United States. Growth in LSS deployment is anticipated to accelerate in response to growing electricity demand and utility, state, and federal decarbonization goals. This continued expansion hinges, in part, on the continued support of local residents and decision-makers in communities hosting LSS projects. Understanding the perceptions and attitudes of existing LSS neighbors is critical to inform and enable future LSS deployment, and to improve outcomes for those host communities. As of 2022, there were more than 10 million U.S. homes within 3 miles of LSS plants. Yet, until recently, no comprehensive study had examined the experiences and perceptions of these LSS neighbors. In 2023, a Berkeley Lab team worked with the University of Michigan and Michigan State University to conduct the first-of-its-kind nationally representative survey of LSS neighbors as part of the Community-Centered Solar Development research project. The survey effort ultimately collected 984 responses from residents within 3 miles of existing LSS projects. The survey results are available for download via the full summary analysis slide deck report, as well as a shorter (~4 page) summary brief. The survey instrument (questionnaire) is also available for download for those interested in understanding the survey design or replicating questions in future research

Good fences make good neighbors: Stakeholder perspectives on the local benefits and burdens of large-scale solar energy development in the United States

In order to meet decarbonization goals, the number of large-scale solar (LSS) facilities in the US is expected to increase considerably. The advantages of LSS over fossil-fueled power generation are numerous and well documented. However, residents living nearby proposed and existing LSS sites have voiced a number of concerns about LSS, including its possible impacts to farmland and agricultural production, biodiversity, stormwater runoff, home and property values, as well as concerns about solar panels' toxicity and safety. While rapid expansion of LSS currently relies on officials permitting and residents being willing to host these systems, the appetite for LSS in some communities may be waning. Here we examine the perceived benefits and burdens of recent LSS developments, conducting 54 interviews with a broad set of stakeholders including residents, officials and developers at seven LSS sites across the US. We focus on identifying residents' most common concerns regarding LSS systems across states, site types, landscapes and ownership structures. We find concerns are associated with either LSS development processes or impacts, and center on the type and amount of information provided, the community's influence over project design, the efficacy of community subscription efforts, as well as projects' economic, environmental, and visual and landscape impacts. Importantly, we also investigate strategies that have been employed to improve perceptions and project outcomes, which include increasing in-person engagement, more explicit discussion of project tradeoffs, third-party intermediaries acting as community champions, and explicit requirements for meaningful local economic benefits

Controlling anoxic tolerance in adult Drosophila via the cGMP–PKG pathway

In this study we identify a cGMP-dependent protein kinase (PKG) cascade as a biochemical pathway critical for controlling low-oxygen tolerance in the adult fruit fly, Drosophila melanogaster. Even though adult Drosophila can survive in 0% oxygen (anoxia) environments for hours, air with less than 2% oxygen rapidly induces locomotory failure resulting in an anoxic coma. We use natural genetic variation and an induced mutation in the foraging (for) gene, which encodes a Drosophila PKG, to demonstrate that the onset of anoxic coma is correlated with PKG activity. Flies that have lower PKG activity demonstrate a significant increase in time to the onset of anoxic coma. Further, in vivo pharmacological manipulations reveal that reducing either PKG or protein phosphatase 2A (PP2A) activity increases tolerance of behavior to acute hypoxic conditions. Alternatively, PKG activation and phosphodiesterase (PDE5/6) inhibition significantly reduce the time to the onset of anoxic coma. By manipulating these targets in paired combinations, we characterized a specific PKG cascade, with upstream and downstream components. Further, using genetic variants of PKG expression/activity subjected to chronic anoxia over 6 h, ~50% of animals with higher PKG activity survive, while only ~25% of those with lower PKG activity survive after a 24 h recovery. Therefore, in this report we describe the PKG pathway and the differential protection of function vs survival in a critically low oxygen environment
