The UN Goldstone Report and retraction: an empirical investigation
The United Nations Goldstone Report criminalized self-defense against state-sponsored or state-perpetrated terror. We use voting on the two UN General Assembly resolutions relating to the Goldstone Report to study whether support for the Goldstone principle of criminalization of self-defense against terror was influenced by countries' political institutions. Our results, using two different measures of political institutions, reveal systematic differences in voting by democracies and autocracies: as an example, based on the Chief-in-Executive measure of political institutions, a country with the highest democracy score was some 55 percentage points less likely to vote in favor of the second of the two UN Goldstone resolutions and some 55 percentage points more likely to abstain than a country with the highest autocratic score. The differences between democracies and autocracies in willingness to initiate symmetric welfare are therefore also reflected in differences in sensitivities to loss of life and harm in asymmetric warfare, through broad support by democracies, but not by autocracies, for legitimacy of self-defense against state-supported or state-perpetrated terror. The Goldstone Report is unique among United Nations reports in having been eventually repudiated by its principal author

Landscape diversity and the resilience of agricultural returns: a portfolio analysis of land-use patterns and economic returns from lowland agriculture
<p>Abstract</p> <p>Background</p> <p>Conventional agriculture is increasingly based on highly specialized, highly productive farms. It has been suggested that 1) this specialization leads to farms that lack resilience to changing market and environmental conditions; and 2) that by decreasing agricultural diversity, the resilience of the farming system also decreases.</p> <p>Methods</p> <p>We used agricultural gross margin (GM) forecasts from 1966 to 2010 and remote sensing data from agricultural landscapes in the lowland UK, in conjunction with modern portfolio theory, to test the hypothesis that decreasing land-use diversity results in landscapes that provide higher, but more volatile, economic returns. We considered the role of spatial scale on the expected levels of volatility and resilience of agricultural returns.</p> <p>Results</p> <p>We found that: 1) there was a strong linear trade-off between expected GMs and the expected volatility of those GMs in real lowland agricultural landscapes in the UK; 2) land-use diversification was negatively correlated with expected GMs from agriculture, and positively correlated with decreasing expected volatility in GMs; 3) the resilience of agricultural returns was positively correlated with the diversity of agricultural land use, and the resilience of agricultural returns rose quickly with increased land-holding size at small spatial extents, but this effect diminished after landholdings reached 12,000 hectares.</p> <p>Conclusions</p> <p>Land-use diversity may have an important role in ensuring resilient agricultural returns in the face of uncertain market and environmental conditions, and land-holding size plays a pivotal role in determining the relationships between resilience and returns at a landscape scale. Creating finer-grained land-use patterns based on pre-existing local land uses may increase the resilience of individual farms, while maintaining aggregate yield across landscapes.</p
