    Non-Peer ReviewedNo-till farming (NT) is increasing in the Canadian Prairies in recent years because of the economic and environment benefits and its potential to sequester atmospheric carbon into the soil. Because surface residue and stubble act as insulation and impedes the exchange rate of thermal energy between the soil and the atmosphere, lower root-zone temperatures in the NT fields compared with that in the conventionally tilled (CT) fields were widely observed in the spring. Some studies found that low temperatures under NT persisted to the mid-season or throughout the whole growing season. Little attention, however, has been paid to the impact of the cooling effect of NT on the grain yield of wheat. The objective of this study was to investigate if NT could alleviate heat stress and benefit yield

    Foreign Policy and the Ideology of Post-ideology: The Case of Matteo Renzi’s Partito Democratico

    The post-communist Italian Left has experienced a long phase of ideational misalignment between ideas placed at different levels, as a qualified discursive institutionalist approach demonstrates. Background public philosophies have often clashed with post-communist political ideology, while foreign policy programmes have often contradicted specific policies. Under the leadership of Matteo Renzi, however, the PD is now experiencing a moment of remarkable ideational consistency. Rather than being founded on entirely new premises, this new consensus folds old elements into new ones and shows all the defining traits of post-ideology. Yet, by espousing post-ideology, Renzi is making an ultimately ideological move whose limitations may soon start to show
