Assessing U.S. Food Wastage and Opportunities for Reduction

Reducing food wastage is one of the key strategies to combat hunger and sustainably feed the world. We present a comprehensive analysis of available data, despite uncertainties due to data limitation, indicating that the U.S. loses at least 150 million metric tonnes (MMT) of food between farm and fork annually, of which about 70 MMT is edible food loss. Currently, \u3c2% of the edible food loss is recovered for human consumption. A reasonably-attainable goal of food waste reduction at the source by 20% would save more food than the annual increase in total food production and would feed millions of people. This is an opportunity of significant magnitude, offering food security and resource and environmental benefits with few negatives. Seizing this opportunity requires technological innovation, policy intervention, and public outreach. This U.S.-based analysis is pertinent to other mid- to high-income countries

Looking ahead to the future of GeogEd: Creating spaces of exchange between communities of practice

As part of the special issue marking the transition of the Higher Education Research Group to the Geography and Education Research Group, in this final paper we argue that the reformed group has a key role to play in promoting spaces of exchange between the communities of practice that have a stake in the shared endeavours of geography and education. We draw on structured conversations from the group’s launch event, existing literature, and our particular vantage points to identify a range of influences – both heritages that we work with and challenges that we face – that shape the interplay of geography and education in our pedagogical contexts. We argue that the GeogEd Research Group can create spaces of productive exchange between three communities of practice: geographies of education research, geography education research, and pedagogic research. As the research group brings these communities of practice together, it facilitates dialogue, creates new avenues for research, and connects and enhances geography teaching practice across education levels

How special are Brightest Group and Cluster Galaxies?

We use the Sloan Digital Sky Survey to construct a sample of 625 brightest group and cluster galaxies (BCGs) together with control samples of non-BCGs matched in stellar mass, redshift, and color. We investigate how the systematic properties of BCGs depend on stellar mass and on their privileged location near the cluster center. The groups and clusters that we study are drawn from the C4 catalogue of Miller et al. (2005) but we have developed improved algorithms for identifying the BCG and for measuring the cluster velocity dispersion. Since the SDSS photometric pipeline tends to underestimate the luminosities of large galaxies in dense environments, we have developed a correction for this effect which can be readily applied to the published catalog data. We find that BCGs are larger and have higher velocity dispersions than non-BCGs of the same stellar mass, which implies that BCGs contain a larger fraction of dark matter. In contrast to non-BCGs, the dynamical mass-to-light ratio of BCGs does not vary as a function of galaxy luminosity. Hence BCGs lie on a different fundamental plane than ordinary elliptical galaxies. BCGs also follow a steeper Faber-Jackson relation than non-BCGs, as suggested by models in which BCGs assemble via dissipationless mergers along preferentially radial orbits. We find tentative evidence that this steepening is stronger in more massive clusters. BCGs have similar mean stellar ages and metallicities to non-BCGs of the same mass, but they have somewhat higher alpha/Fe ratios, indicating that star formation may have occurred over a shorter timescale in the BCGs. Finally, we find that BCGs are more likely to host radio-loud active galactic nuclei than other galaxies of the same mass, but are less likely to host an optical AGN. The differences we find are more pronounced for the less massive BCGs.Comment: Replaced with slightly modified version accepted by MNRAS. 28 pages, 25 figures.

Precision Measurement of the Beam-Normal Single-Spin Asymmetry in Forward-Angle Elastic Electron-Proton Scattering

A beam-normal single-spin asymmetry generated in the scattering of transversely polarized electrons from unpolarized nucleons is an observable related to the imaginary part of the two-photon exchange process. We report a 2% precision measurement of the beam-normal single-spin asymmetry in elastic electron-proton scattering with a mean scattering angle of theta_lab = 7.9 degrees and a mean energy of 1.149 GeV. The asymmetry result is B_n = -5.194 +- 0.067 (stat) +- 0.082 (syst) ppm. This is the most precise measurement of this quantity available to date and therefore provides a stringent test of two-photon exchange models at far-forward scattering angles (theta_lab -\u3e 0) where they should be most reliable
