An improved reactive power optimization algorithm of distribution system is presented, which incorporates distributed generations and running cost. By this method, the comprehensive cost can be reduced to the potential minimum value. Firstly, based on the function between the operations of preliminary main equipments and the comprehensive cost, the optimization model is presented to reduce the comprehensive cost. Secondly, the traditional back/forward sweep method is improved by updating DGs reactive power amount during each iterative step timely. The changing value is gained according to the voltage deviation amount. Thirdly, a novelty hybrid PSO algorithm is presented, which can adapt binary variables and discrete variables in unison. Lastly, the algorithm is realized on the platform of VC++ 6.0 and the case study is done. The results have proved that this method can reduce the comprehensive cost and the optimization problem can be solved quickly.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.
