The article presents the case study of wastewater disposal facilities development performed by the State Unitary Enterprise ‘Vodokanal of St. Petersburg’ which is regarded as one of the ‘green cases’ being implemented in the Russian Federation. It was emphasized that the Vodokanal of St. Petersburg ‘green case’ holds both sectoral and regional significance. Authors discuss approaches towards development and stage-by-stage implementation of reconstruction and modernization programs as to existing treatment facilities and for designing new ones. The implementation stages are considered from the standpoint of improving the environmental and technological policy of the enterprise. The implementation results for modern wastewater treatment techniques (mainly concerning nitrogen and phosphorus removal) are presented. The company’s experience on operating wastewater sludge incineration installations is described. The article demonstrates an urgent need for a detailed analysis of technological and economic risks and opportunities during strategic planning and designing St. Petersburg Water Supply and Disposal Scheme due to the transition to new BAT-based technological regulation in the field of environmental protection. The role of the best available techniques in fulfilling the requirements of the Convention on the Protection of the Marine Environment of the Baltic Sea Region (HELCOM) is emphasized. Authors describe technical solutions implemented by the State Unitary Enterprise ‘Vodokanal of St. Petersburg’ which allowed to remove the enterprise from HELCOM environmental «hot spots» list. Approaches towards further activities on sewage sludge and ash recycling are presented. The article formulates recommendations on improving BAT-related regulatory legal acts based on the results of the case study and notes the expediency for developing a national strategy in the field of using sewage sludge as a secondary resource.

The Genesis and Internal Dynamics of El Salvador's People's Revolutionary Army, 1970–1976

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AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador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.

Culture and the plasticity of perception

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.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.
