Food for all: An agent-based model to explore the emergence and implications of cooperation for food storage

Abstract

A consistent access to food is paramount for humans at individual and group level. Besides providing the basic nutritional needs, access to food defines social structures and has stimulated innovation in food procurement, processing and storage. We focus on the social aspects of food storage, namely the role of cooperation for the emergence and maintenance of common stocks. Cooperative food stocks are examined here as a type of common-pool resource, where appropriators must cooperate to avoid shortage (i.e. the tragedy of commons). ‘Food for all’ is an agent-based model in which agents face the social dilemma of whether or not to store in a cooperative stock, adapting their strategies through a simple reinforcement learning mechanism. The model provides insights on the evolution of cooperation in terms of storage efficiency and considering the presence of social norms that regulate reciprocity. For cooperative food storage to emerge and be maintained, a significant dependency on the stored food and some degree of external pressure are needed. In fact, cooperative food storage emerges as the best performing strategy when facing environmental stress. Likewise, an intermediate control over reciprocity favours cooperation for food storage, suggesting that concepts of closed reciprocity are precursors to cooperative stocks, while excess control over reciprocity is detrimental for such institution.     

Land reform in the 1950s in Italy and the United States: the thinking of Mario Einaudi

The article discusses the thinking of Mario Einaudi in relation to the ambitious measures with which the Italian government sought to move towards land reform in the immediate post–war period. Einaudi, an intellectual and academic, was by birth Italian but moved to the United States during the Fascist period. Like his father Luigi, the noted economist, he was convinced of the need to stimulate the free market in land in order to increase productivity and modernise cultivation methods; in his writings he repeatedly sought to develop a plan of action that would facilitate collaboration between Rome and Washington in this field, identifying the Tennessee Valley Authority approach as especially suited to the Italian case. However, while his ideas achieved a good public airing, they had a limited impact: on the political front, Cold War priorities pushed Italian and US Marshall Plan experts more towards the redistribution of landownership than towards stimulating the productivity of agricultural businesses, in the attempt to rapidly build a consensus behind the government; and on the cultural front, at the end of the 1950s the issue of backwardness in the rural South started to be interpreted in terms of cultural and social anthropology, an approach which did not directly relate to the development of political programmes.     

‘Hidden from view’?: an analysis of the integration of women’s history and women’s voices into Australia’s social history exhibitions

ABSTRACT

‘Women have mostly been left out of history’, boldly asserted Elizabeth Willis in her exhibition text for The Story of Victoria in 1985. Taking Willis’ statement as a starting point, this article aims to trace firstly how women have been rewritten into Australia’s social history exhibitions focusing on the use of voice as a strategy to do so, and secondly how these voices have changed historical master narratives – by allowing a shift from a big picture history to intimate and deeply personal stories that recast our understanding of the past in ways that are inclusive of gendered experiences. We investigate the use of the curatorial voice as reflected in Willis’ work, aligning it with the notion of curatorial activism, before exploring the changing curatorial practices that expanded the potential for an interpretive approach that incorporated the voice of the subjects themselves as a central component in the telling of history. We then analyse the impact of these strategies on traditional understandings of the past through three exhibitions developed by Melbourne Museum over 30 years: The Story of Victoria, a successor exhibition The Melbourne Story, and their Great War centenary exhibition, WWI: Love & Sorrow.
