Corporate intranet implementation : managing emergent technologies and organizational practices

This paper examines the adoption and development of intranets in large business organizations. The authors demonstrate that intranet technology introduces a host of new managerial and technical challenges and requires new approaches to IS development. Evidence from two European corporations indicates that the traditional division of labor and definition of work roles in IS development breaks down. The distinction between developers and users becomes increasingly blurred and new organizational roles and structures associated with intranets are emerging. However, ready-made organizational models for implementing and managing intranets do not exist and the two organizations in this study have followed two different approaches. One organization favors a “planned change” approach, emphasizing management control and careful planning. The other organization prefers an “improvisational” approach, emphasizing experimentation, innovation and local initiative.

Substrate-induced coagulation (SIC) of nano-disperse carbon black in non-aqueous media : a method of manufacturing highly conductive cathode materials for Li-ion batteries by self-assembly

Substrate-induced coagulation (SIC) is a coating process based on self-assembly for coating different surfaces with fine particulate materials. The particles are dispersed in a suitable solvent and the stability of the dispersion is adjusted by additives. When a surface, pre-treated with a flocculant e.g. a polyelectrolyte, is dipped into the dispersion, it induces coagulation resulting in the deposition of the particles on the surface. A non-aqueous SIC process for carbon coating is presented, which can be performed in polar, aprotic solvents such as N-Methyl-2- pyrrolidinone (NMP). Polyvinylalcohol (PVA) is used to condition the surface of substrates such as mica, copperfoil, silicon-wafers and lithiumcobalt oxide powder, a cathode material used for Li-ion batteries. The subsequent SIC carbon coating produces uniform layers on the substrates and causes the conductivity of lithiumcobalt oxide to increase drastically, while retaining a high percentage of active battery material.

Understanding Marxism

Marxism as an intellectual movement has been one of the most important and fertile contributions to twentieth-century thought. No social theory or political philosophy today can be taken seriously unless it enters a dialogue, not just with the legacy of Marx, but also with the innovations and questions that spring from the movement that his work sparked, Marxism.

Marx provided a revolutionary set of ideas about freedom, politics and society. As social and political conditions changed and new intellectual challenges to Marx’s social philosophy arose, the Marxist theorists sought to update his social theory, rectify the sociological positions of historical materialism and respond to philosophical challenges with a Marxist reply. This book provides an accessible introduction to Marxism by explaining each of the key concepts of Marxist politics and social theory. The book is organized into three parts, which explore the successive waves of change within Marxist theory and places these in historical context, while the whole provides a clear and comprehensive account of Marxism as an intellectual system.
