The Knowledge Age or the Age of Ignorance and the Decline of Freedom?

Increasingly knowledge has become a determining factor in achieving life’s potential and is the currency of the age. Without access to Information an individuals’ knowledge base cannot be enriched and without knowledge the individual becomes increasingly powerless. Advances in technology have provided opportunities for some to add to their stock of knowledge but access to sources of information is uneven and can lead to social unrest. The availability of information is an important factor in managing change and empowering citizens. The question about information and power then becomes one of ownership or sovereignty of the information. If we are to create an open society then we need to ensure that there is open access to knowledge through flexible and intelligent information systems that are available for all. In this paper we consider if we are truly entering the knowledge age or the age of ignorance.     

Virtual Action Research for Virtual Organisations?

Business organisations have always existed in a constantly changing environment. To survive it is necessary for them to adapt and adjust to the changes. When analysing complex entities, such as organisations, researchers have frequently adopted the methods of action research. But with the advent of greater use of information and communication technology businesses are changing in their composition and one practical manifestation of this is the rise of virtual teams. Virtual teams reflect the trend for an organisation to comprise ‘satellites’ or clusters of expertise in different parts of the globe. Such a transformation of what we can now take as an organisation creates new challenges for managers and for those inquiring into organisational problems. In this paper we attempt to address the question whether action research is any longer a valid way of organisational intervention for the researcher and consultant alike. In this paper we describe field research in which a soft method of Action Research was used during the analysis phase of IS development as a means of understanding the problem domain, identifying information requirements, evaluating technologies and reducing conflicts. The research was conducted between two institutions that were separated by several thousand miles and all participants connected from individual locations using virtual synchronous ICT. The study provided insight into the use of AR in virtual settings and as a means of conflict resolution in virtual teams. The findings have implications for IS development (which is increasingly conducted in virtual teams), education and management among others.     

GTPase activity of dynamin and resulting conformation change are essential for endocytosis

Dynamin is a large GTPase with a relative molecular mass of 96,000 (Mr 96K) that is involved in clathrin-mediated endocytosis and other vesicular trafficking processes. Although its function is apparently essential for scission of newly formed vesicles from the plasma membrane, the nature of dynamin's role in the scission process is still unclear. It has been proposed that dynamin is a regulator (similar to classical G proteins) of downstream effectors. Here we report the analysis of several point mutants of dynamin's GTPase effector (GED) and GTPase domains. We show that oligomerization and GTP binding alone, by dynamin, are not sufficient for endocytosis in vivo. Rather, efficient GTP hydrolysis and an associated conformational change are also required. These data argue that dynamin has a mechanochemical function in vesicle scission.     

Cooperation,power, and the impact of information systems

Imagination suggests that the computer as a communication tool is potentially a significant factor in enhancing cooperative work, especially where the participants are located over a physical or temporal distance. Implementation of innovative information technology offers enhancement of operational efficiency to an enterprise in a turbulent business environment. Communications and decision making are inseparable. Industrial democracy (ID) is a particular arrangement of decisionmaking power where decision makers have to be informed and decisions have to be communicated. Cooperation implies a redistribution of power and the weakening of the traditional management organizational heirarchy. Cogently, this effect is mirrored by the potential of management information systems to redistribute information and, hence, power within an enterprise. The response of traditional management personnel to the threat of information technology (IT) to established positions of authority, is one of defense. Conventional systems analysis is unsuited for the design task of ID information systems. The methods employed by systems analysis preserve or reproduce the formal hierarchical structure of managerial organization. Soft systems methodology is explored as a means of confronting the sociopolitical factors present in the specification of information systems for an ID.     

Validating Action Research Field Studies: PEArL

The difficulty of establishing the validity of Action Research field studies has been well documented. Enabling interested individuals to follow the route of inquiry, or recover the inquiry process, has provided some means of addressing the difficult issue of validation. Such an approach, however, still fails to provide a sense of the manner in which an inquiry was undertaken, which can be important when individuals, participants in the inquiry or otherwise, are making their own judgments concerning validity. In this paper we argue that by supporting any interested individuals in making their own judgments concerning the manner in which the inquiry process was undertaken, it is possible for a public perception of the authenticity and credibility, or character, of that inquiry process to emerge. We argue that such a perception is an essential aspect of making judgments concerning the validity of an Action Research project.
