Between Planning and Heritage: Cultural Parks and National Heritage Areas
Abstract The number of cultural parks and heritage areas is increasing in Europe and the United States. Those are spreading over other areas where the economic sectors related to tourism and leisure gain weight. Heritage areas or parks are heterogeneous initiatives that place cultural heritage at the heart of spatial planning policy and economic development, aiming at the reinvention of large territories and local community participation in planning. Their relevance stems from their potential influence on the territorial configuration of broad regions and their impact upon the articulation of traditional protected areas. Notwithstanding this, they have attracted scant academic attention so far.
A natural language discourse model to explain linear programming models and solutions
Abstract This paper presents a natural language (i.e., English) discourse model to explain a linear programming model and, possibly, its computed solution (which need not be optimal). Drawing from earlier syntactic translations, a semantic model is presented, based on economic input-output relations commonly found in large-scale linear programs. These are then shown how to form rule-driven explanations, which comprises a fundamental component of an intelligent mathematical programming system.
