Restoring balance: How history tilts the scales against privacy. An Actor-Network Theory investigation

In this paper we problematize the metaphor of balance employed in the area of information privacy. Using Actor-Network Theory we conduct an historical investigation into the continuous release of the same personal data over the course of eight decades. Through the examination of actual enactments of balance over time we find that, in practice, balancing acts are conducted at local levels by local actor-networks within organizations, with limited overall organizational knowledge, raising challenges around interpreting statements made by organizational spokespersons. We also find a surprising lack of knowledge possessed by these local actor-networks about what is subsequently done with personal data and the extent to which networks that extend beyond the organization gravitate towards and form around available data. Through tracing and revealing this historical Actor-Network Theory investigation provides a means of probing and examining actual acts of balance in the area of information privacy and, through revelation, aid in the creation of the possibility of bringing the act of balance more in line with the concept.     

The technological gatekeeper

The present study identifies a two-step flow process of communication mediated by technological gatekeepers for scientific and technical fields characterized by dynamic information environments. Peer identification and a supervisory recognition of the phenomenon validate the gatekeeper finding. Certain characteristics of this study differ from previous research. The external communication needs of military in-house researchers are mitigated greatly by the infusion of technical information into the laboratory which is a part of the everyday activities of the organization. Gatekeepers are differentiated by topic and not the media monitored. Finally, the gatekeeper phenomenon is implicitly recognized, even though the development may be spontaneous; development that results because either the formal media leave a void in information needs or that engineers are not trained in the use of the formal information sources. In either case, the technological gatekeeper is a natural response to an information need.     

A Tale of Two Models: Comparing structuralist and neoclassical computable general equilibrium models for South Africa

This paper compares two working models of the South African economy, an orthodox, neoclassical computable general equilibrium model in which savings drive investment, and a more structuralist, eclectic, model for which there is an independent investment function. Both models are calibrated to the same social accounting matrix. Comparative statics of simplified prototype models are presented and identical simulations with the corresponding applied versions are compared. It is seen that the neoclassical model fully supports the principles of the 'Washington Consensus' while the structuralist model requires a far more heterodox set of policies to avoid slow growth or high inflation.     

On measuring the utilization rate of employed labour

This paper deals with the factors that influence plans to retire from the labour force. We use a theoretical model to explain the empirical findings from a bivariate probit model relating economic, demographic, and social characteristics to retirement plans for over 7000 women and men between the ages of 40 and 64. The results of the analysis concerning retirement intentions suggest that personal, economic and household characteristics are more important determinants of retirement plans for women than men.     

Japanese management style in China? Production practices in Japanese manufacturing plants

Through an examination of twenty Japanese owned manufacturing plants in China, this article seeks to question the usefulness of identifying Japanese competitive success as being associated with specific Japanese production management techniques. Rather Japanese plants adopt, seemingly profitably, various and differentiated production methods, depending on local and parent company circumstances.     

Business @ the Speed of Thought

Bill Gates' first book, "The Road Ahead", focused on the broad impact of technology. His new book, "Business @ the Speed of Thought", asks what this means for business. How should firms organize themselves differently? In what new ways should information flow? What metrics can managers use to judge how far down the path they are to what he calls the "digital nervous system" approach? In this article, Mr Gates comments on some of the themes of the book, including issues within Microsoft itself.     

The Target Zone Model, Non-Linearity and Mean Reversion: is the Honeymoon Really Over?

We estimate a target zone model for three ERM exchange rates for 1983–6 and 1987–91 by the method of simulated moments, taking account of the continuous time specification by using daily data with the interruptions of holidays and weekends. Specification tests are unable to reject the model. The estimates imply, however, an essentially linear relationship between the exchange rate and the fundamentals, with a very limited 'honeymoon effect'. Using Monte Carlo simulations, calibrated on the estimates, we find that standard tests for mean reversion of the exchange rate would largely reject the target zone model when, in fact, it held.     

Knowledge transformation in project networks: A speech act level cross‐boundary analysis

Researchers stress the importance of understanding knowledge transformation in projects. To explore how knowledge is transformed across organizational and specialization boundaries in project networks, we observed 22 knowledge transformation cases in two project networks. We found that new knowledge was created across specialization boundaries and that knowledge was altered across organizational boundaries. When both organizational and specialization boundaries were crossed, new knowledge was created. From these findings, we developed a set of propositions and formulated these into a model of knowledge transformation in project networks. This research contributes to a better understanding of knowledge transformation processes and outcomes in project networks.     

Industrial restructuring and regional policy

The paper examines the changing regional specialisation of UKemployment over the period 1971-94, analysing the extent towhich UK regional policy has altered the industrial structureof the Assisted Area regions, making them less vulnerable toeconomic change. All regional economies are found to have becomemore specialised, but industry has become less geographicallyconcentrated leading to a convergence of regional industrialstructures towards the national pattern of employment. Thesetrends are stronger in the Assisted Areas, and have been promotedby the operation of regional policy, but the major policy effectoccurs through the large-scale capital grants which have acceleratedthe employment decline of the traditional manufacturing industriesin which the Assisted Areas were relatively over-represented.
