Collaborative systems for enhancing the analysis of social surveys: the grid enabled specialist data environments
This paper describes a group of online services which are designed to support social
survey research and the production of statistical results. The 'Grid Enabled Specialist
Data Environment' (GESDE) services constitute three related systems which offer
facilities to search for, extract and exploit supplementary data and metadata concerned
with the measurement and operationalisation of survey variables. The services also offer
users the opportunity to deposit and distribute their own supplementary data resources for
the benefit of dissemination and replication of the details of their own analysis.
The GESDE services focus upon three application areas: specialist data relating to the
measurement of occupations; educational qualifications; and ethnicity (including
nationality, language, religion, national identity). They identify information resources
related to the operationalisation of variables which seek to measure each of these
concepts - examples include coding frames, crosswalk and translation files, and
standardisation and harmonisation recommendations. These resources constitute
important supplementary data which can be usefully exploited in the analysis of survey
data. The GESDE services work by collecting together as much of this supplementary
data as possible, and making it searchable and retrievable to others. This paper discusses
the current features of the GESDE services (which have been designed as part of a wider
programme of ‘e-Science’ research in the UK), and considers ongoing challenges in
providing effective support for variable-oriented statistical analysis in the social sciences
Metadata Creation, Transformation and Discovery for Social Science Data Management: The DAMES Project Infrastructure
This paper discusses the use of metadata, underpinned by DDI (Data Documentation Initiative), to support social science data management. Social science data management refers broadly to the discovery, preparation, and manipulation of social science data for the purposes of research and analysis. Typical tasks include recoding variables within a dataset, and linking data from different sources. A description is given of the DAMES project (Data Management through e-Social Science), a UK project which is building resources and services to support quantitative social science data management activities. DAMES provides generic facilities for performing (and recording) operations on data. Specific resources include support for analysis through micro-simulation, and support for access to specialist data on occupations, educational qualifications, measures of ethnicity and immigration, social care, and mental health. The DAMES project tools and services can generate, use, transform, and search metadata that describe social science datasets (including microdata from social survey datasets and aggregate-level macrodata). On DAMES, these metadata are described by various standards including DDI Version 2, DDI Version 3, JSDL (Job Submission Definition Language), and the purpose-designed JFDL (Job Flow Definition Language). The paper describes how DAMES uses metadata with a range of resources that are integrated with a job execution infrastructure, a Web portal, and a tool for data fusion

Updating Carbon Density and Opportunity Cost Parameters in Deforesting Regions in the GCOMAP Model
This paper explores the economics of carbon density and carbon pricing in forestry and in deforested areas. According to a footnote, this paper was commissioned by the [United Kingdom] Office of Climate Change as background work to its report 'Climate Change: Financing Global Forests' (the Eliasch Review)
Enabling quantitative data analysis through e-infrastructures
This paper discusses how quantitative data analysis in the social sciences can engage with and exploit an e-Infrastructure. We highlight how a number of activities which are central to quantitative data analysis, referred to as ‘data management’, can benefit from e-infrastructure support. We conclude by discussing how these issues are relevant to the DAMES (Data Management through e-Social Science) research Node, an ongoing project that aims to develop e-Infrastructural resources for quantitative data analysis in the social sciences
Physics Opportunities with the 12 GeV Upgrade at Jefferson Lab
This white paper summarizes the scientific opportunities for utilization of
the upgraded 12 GeV Continuous Electron Beam Accelerator Facility (CEBAF) and
associated experimental equipment at Jefferson Lab. It is based on the 52
proposals recommended for approval by the Jefferson Lab Program Advisory
Committee.The upgraded facility will enable a new experimental program with
substantial discovery potential to address important topics in nuclear,
hadronic, and electroweak physics.Comment: 64 page
GTOSat: Radiation Belt Dynamics from the Inside
GTOSat, a 6U SmallSat integrated and tested at NASA Goddard Space Flight Center (GSFC), has a scheduled launch date of July 31st, 2022, on an Atlas V. From a low inclination geosynchronous transfer orbit (GTO), GTOSat has the primary science goal of advancing our quantitative understanding of acceleration and loss of relativistic electrons in the Earth’s outer radiation belt. It will measure energy spectra and pitch angles of both the seed and the energized electron populations simultaneously using a compact, high-heritage Relativistic Electron Magnetic Spectrometer (REMS) built by The Aerospace Corporation. A boom-mounted Fluxgate Magnetometer (FMAG), developed by NASA GSFC, will provide 3-axis knowledge of the ambient local magnetic field. The spacecraft bus uses a combination of commercial and in-house/custom designed components. Design, integration, and testing of the spacecraft bus was performed by a small, dedicated team at GSFC. Throughout development GTOSat has encountered numerous challenges, expected and unexpected, that we’re ready to share with the community
Electric dipole moments and the search for new physics
Static electric dipole moments of nondegenerate systems probe mass scales for
physics beyond the Standard Model well beyond those reached directly at high
energy colliders. Discrimination between different physics models, however,
requires complementary searches in atomic-molecular-and-optical, nuclear and
particle physics. In this report, we discuss the current status and prospects
in the near future for a compelling suite of such experiments, along with
developments needed in the encompassing theoretical framework.Comment: Contribution to Snowmass 2021; updated with community edits and
