‘Globalisation’ and African export crop agriculture

It is commonly agreed that Africa has become increasingly marginalised within the current global economy. However, there are few existing attempts to identify the precise contours of this marginalisation or to explicate the dynamics giving it a precise shape. Against the background of a discussion of theoretical entry points to this problem, as well as of some of its broad quantitative dimensions, this article attempts to develop working hypotheses focused on the marginalisation/restructuring of African export crop agriculture.     

A Theoretical and Analytical Synthesis of Autopoiesis and Sociolinguistics for the Study of Organisational Communication

The purpose of this paper is threefold. First, we propose a systemic view of communication based in autopoiesis, the theory of living systems formulated by Maturana & Varela (1980, 1987). Second, we show the links between the underpinning assumptions of autopoiesis and the sociolinguistic approaches of Halliday (1978), Fairclough (1989, 1992, 1995) and Lemke (1995, 1994). Third, we propose a theoretical and analytical synthesis of autopoiesis and sociolinguistics for the study of organisational communication. In proposing a systemic theory for organisational communication, we argue that traditional approaches to communication, information, and the role of language in human organisations have, to date, been placed in teleological constraints because of an inverted focus on organisational purpose-the generally perceived role of an organisation within society-that obscure, rather than clarify, the role of language within human organisations. We argue that human social systems are, according to the criteria defined by Maturana and Varela, third-order, non-organismic living systems constituted in language. We further propose that sociolinguistics provides an appropriate analytical tool which is both compatible and penetrating in synthesis with the systemic framework provided by an autopoietic understanding of social organisation.     

Comment on James E. Rosenbaum,Linda K. Stroh,and Cathy A. Flynn's “Lake Parc Place: A study of mixed‐income housing”

Abstract

Rosenbaum, Stroh, and Flynn confirm existing community leader perceptions that this model mixed‐income development in the predominantly low‐income South Side of Chicago has produced a positive residential environment. Increased tenant voice, not role modeling, seems to be a factor in producing increased resident satisfaction with the building and a strong sense of commitment to the mixed‐income alternative to exclusively low‐income housing projects. The extra resources invested in physical improvements and the extraordinary media attention paid to this model project may have created a “Hawthorne effect,” which also produced higher levels of satisfaction. The existence of this successful model is not sufficient to provide more housing alternatives; community‐based advocacy for more mixed‐income developments is needed.     

Testing proximity versus directional voting using experiments

A long-running debate about how voters use issues to evaluate candidates pits the proximity theory of voting against directional theory. Using surveys, both sides of the debate have found support for their preferred theory, but disagreement remains because of differing ways of analyzing the data. Lewis and King (2000) point out that these researchers make assumptions that bias results in favor of their theory. To avoid these difficulties, our approach creates fictitious candidates with controlled positions, presents these candidates to randomly-assigned subjects, and examines the relationship between subjects’ evaluations of these candidates and their ideological beliefs as a neutral test of proximity and directional theory. Our results provide reasonably strong support for proximity theory but little for directional theory.
