The robustness of the optimal weighted majority rule to probability distortion

This study identifies the optimal collective decision rule in a dichotomous symmetric setting, allowing for probabilities distortion as originally assumed by Tversky and Kahneman (Journal of Risk and Uncertainty 5(4):297–323, 1992). We show that previous results that identified the weighted majority rule as the optimal one, and did not consider subjective probabilities, are robust to such distortion in the sense that neither the rule nor the weights are changed.     

The IHRA Definition of Antisemitism: Defining Antisemitism by Erasing Palestinians

The IHRA definition is one of the most contentious documents in the history of efforts to combat antisemitism. Although it first became well known in the UK as a result of disputes within the Labour Party, the definition reaches well beyond that context, and has been adopted by universities, city councils, and governments. With its intensive focus on the critique of Israel as a marker of antisemitism, the IHRA definition has been heavily implicated in the suppression of Israel-critical speech in recent years. This article is among the first to adopt a global perspective on the definition—both its history and its content—clarifying the political stakes of this definition and broader paratextual apparatus for a general audience, and provides an explanation of why it should be rejected rather than used to censor Israel-critical speech.     

Using subsidised seed to catalyse demand-driven bean seed systems in Malawi

Through an innovative public-private partnership, Demeter Agricultural Limited, along with the Malawi National Bean Programme and the International Center for Tropical Agriculture, supplied 2,559 tons of certified bean seed between 2009 and 2012 through the government's Targeted Farm Input Programme. Farmers were satisfied with the variety supplied, timeliness of the operation, pack size, and information provided. Growing numbers also accessed new improved varieties, from 264,661 households in 2009 to 344,200 in 2012. These emerging farmers’ demands and the subsequent DAL responses suggest a base for building sustainable delivery systems. However, decentralised seed-based systems will be needed for promoting varieties suited to micro-ecological niches.     

Polarised narratives and complex realities in Tanzania’s Southern Agricultural Growth Corridor

This article assesses the controversy surrounding a high-profile agricultural investment initiative, the Southern Agricultural Growth Corridor of Tanzania (SAGCOT), which aims to modernise, commercialise, and transform Tanzania’s agricultural sector. Drawing on a review of SAGCOT literature and findings from consultations with SAGCOT stakeholders and intended beneficiaries, the article outlines the polarised narratives of “opportunity” and “risk” informing SAGCOT debates, and presents research findings that challenge these narratives. The findings suggest that agricultural investments are rarely as glamorous or as gloomy in practice as the polarised narratives around SAGCOT suggest, and illustrate the challenges involved in directing agricultural investments in ways that balance multiple interests and objectives in practice.     

The Negev: Land,Settlement, the Bedouin and Ottoman and British Policy 1871–1948

Focusing on the sub-district of Beersheba in British Mandatory Palestine, we examine issues of colonial administration, land use, relations between the government and indigenous nomads and extension of government control over marginal regions. Based on archival primary written sources and maps, we assess British Mandatory policy in the Negev, in the contexts of land ownership, settlement and the Bedouin population. The British Mandatory administration inherited a Southern Palestine Negev region that had been affected by a robust Ottoman policy of increasing administrative intervention, policing, land settlement and overall projection of government power. During 30 years of Mandatory rule, the policy was markedly different. The Beersheba sub-district, which incorporated almost half the area of Mandatory Palestine, was a unique administrative unit, populated almost entirely by nomadic Bedouins. Although the Mandatory authorities foresaw land settlement and sedenterisation as a goal in Palestine, they did not apply their administrative apparatus to fulfil this policy in the Negev, neglecting much of it.     

Volatile voters,short-term choices? An analysis of the vote choice determinants of stable and volatile voters in Great Britain†

The increase of electoral volatility in established democracies is typically interpreted as proof that short-term factors are increasingly important determinants of vote choice. The empirical evidence to support this assertion, however, is relatively weak. This paper addresses this question by investigating the impact of both long- and short-term determinants on the vote choices of stable and volatile voters in Britain. Analysis of three British election panels (1992–1997, 1997–2001 and 2005–2010) indicates that short-term factors – especially economic issues – do have more weight in determining the vote choices of volatile voters compared with stable voters. However, the results also reveal that the growth in instability of voting behaviour is driven mainly by the weakening impact of long-term factors and not by increasing importance of short-term determinants of the vote choice. Short-term predictors are becoming more important, therefore, but this gain in strength is in relative rather than absolute terms.     

Petra Kelly: The Other Green

Petra Kelly enjoyed celebrity status as cofounder and "leader" of the German Greens from 1979 to 1990. A prominent theoretician of the Greens, she broke ranks with the party on the issue of joining the Social Democrats in a governing coalition. She proposed, instead, that the Greens remain a radical parliamentary opposition force. Defeated in the All German parliamentary election of 1990, the Greens rejected Kelly's position and ultimately, in 1998, became the governing partner of the SPD. Ostracized and devastated by the 1990 defeat, Kelly spoke of "moving beyond the Greens." In 1992 she died under tragic circumstances. Her name sank into obscurity. Within our globalized era, however, Petra Kelly's ideas have particular salience. She represents the other Green who laid the foundations for a global political theory and for global political action.
