Abstract

Effective explicit algorithms for integrating complex elastoplastic constitutive models, such as those belonging to the Cam clay family, are described. These automatically divide the applied strain increment into subincrements using an estimate of the local error and attempt to control the global integration error in the stresses. For a given scheme, the number of substeps used is a function of the error tolerance specified, the magnitude of the imposed strain increment, and the non‐linearity of the constitutive relations. The algorithms build on the work of Sloan in 1987 but include a number of important enhancements. The steps required to implement the integration schemes are described in detail and results are presented for a rigid footing resting on a layer of Tresca, Mohr‐Coulomb, modified Cam clay and generalised Cam clay soil. Explicit methods with automatic substepping and error control are shown to be reliable and efficient for these models. Moreover, for a given load path, they are able to control the global integration error in the stresses to lie near a specified tolerance. The methods described can be used for exceedingly complex constitutive laws, including those with a non‐linear elastic response inside the yield surface. This is because most of the code required to program them is independent of the precise form of the stress‐strain relations. In contrast, most of the implicit methods, such as the backward Euler return scheme, are difficult to implement for all but the simplest soil models.

Abstract

In 1994, MIT's Sloan School of Management began a global initiative to explore the future of organizations. This initiative was a joint venture between the Sloan faculty and a number of companies from around the world. Part of the early work of the initiative was to shape a clear understanding of the issues organizations must face and resolve in the coming years. We asked three of the principals in this important work to summarize their research approach as a way of setting the stage for this issue's discussion about organizing for the future.

Abstract

Gives an in depth view of the strategies pursued by the world’s leading chief executive officers in an attempt to provide guidance to new chief executives of today. Considers the marketing strategies employed, together with the organizational structures used and looks at the universal concepts that can be applied to any product. Uses anecdotal evidence to formulate a number of theories which can be used to compare your company with the best in the world. Presents initial survival strategies and then looks at ways companies can broaden their boundaries through manipulation and choice. Covers a huge variety of case studies and examples together with a substantial question and answer section.

Abstract

Traditional definitions of decision support systems emphasise their support role in individual decision making and utilise notions of rational choice. By considering decisions as an organisational activity, the interpretation of decision support systems use in organisations can move beyond this technical rational understanding, to include potential political and legitimating roles for these systems. These three possible interpretations are discussed in relation to the implementation of a large decision support system in a local government context described by Dutton (1981). In its technical role, the system was used as part of a rational planning agenda. However, the system was clearly also used politically, to promote particular interests and as a lever in negotiations between various groups. Part of the appeal of the decision support system was the appearance of rationality and technical neutrality that it gave to the planning and decision making process, and the legitimation it provided with external constituents. The paper concludes that an unquestioning acceptance of the technical received view of decision support system use is limiting, and that a more reflective approach to their development, implementation and use is required.

Abstract

Entrepreneurship evolves in and around fields, particularly around the creation of opportunities. A central problem remains that entrepreneurial opportunities are both distributed among and co-created by embedded actors. We propose framing this in cultural terms as a “multiverse problem,” whereby entrepreneurial possibilities are understood within the bounds of a field, but also through traversing adjacent topographies. We argue that a focus on entrepreneurial moments captures important dynamics that bring together adjacent possibles, leading to drastically different pathways. The usefulness of this argument is illustrated in this paper through the articulation of a cultural cartographic approach to mapping and realizing entrepreneurial possibilities. We develop four principles of cultural cartography, apply them to several examples, and demonstrate implications to cultural entrepreneurship and adjacent theoretical traditions.

Abstract

Institutional theory is becoming one of the dominant theoretical perspectives in organization theory and is increasingly being applied in accounting research to study the practice of accounting in organizations. However, most institutional theory research has adequately theorized neither the institutionalization process through which change takes place nor the socio‐political context of the institutional formations. We propose a social theory based framework for grounding and expanding institutional theory to more fully articulate institutionalization processes. Specifically, we incorporate institutional theory and structuration theory and draw on the work of Max Weber in developing a framework of the context and the processes associated with creating, adopting and discarding institutional practices. We propose that the expanded framework depicts the socio‐economic and political context better and more directly addresses the dynamics of enacting, embedding and changing organizational features and processes. Expanding the focus of the institutional theory based accounting research can facilitate a more comprehensive representation of accounting as the object of institutional practices as well as provide a better articulation of the role of accounting in the institutionalization process.
