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.     

Modelling and forecasting liquidity supply using semiparametric factor dynamics

We model the dynamics of ask and bid curves in a limit order book market using a dynamic semiparametric factor model. The shape of the curves is captured by a factor structure which is estimated nonparametrically. Corresponding factor loadings are modelled jointly with best bid and best ask quotes using a vector error correction specification. Applying the framework to four stocks traded at the Australian Stock Exchange (ASX) in 2002, we show that the suggested model captures the spatial and temporal dependencies of the limit order book. We find spill-over effects between both sides of the market and provide evidence for short-term quote predictability. Relating the shape of the curves to variables reflecting the current state of the market, we show that the recent liquidity demand has the strongest impact. In an extensive forecasting analysis we show that the model is successful in forecasting the liquidity supply over various time horizons during a trading day. Moreover, it is shown that the model's forecasting power can be used to improve optimal order execution strategies.     

Is ‘NAFTA Plus’ an Option in the North American Agrifood Sector?

With the implementation of the North American Free Trade Agreement (NAFTA) nearly complete, there are concerns that the easy gains in efficiency have been achieved and that additional steps towards the economic integration of the member countries are required. This poses a distinct challenge to the NAFTA governments, since the agreement did not create trinational institutions with the supranational authority to facilitate the deepening of the new trading environment. In any initiative to further the economic integration of the NAFTA countries, agriculture will be a difficult sector in which to make progress. However, at an aggregate level, the support provided directly to agricultural producers by the NAFTA governments is similar, as are tariffs at an aggregate level. All three countries have devised income support programmes that contain a countercyclical element. In each of these areas, as well as in the operation of ‘green box’ programmes that are consistent with the member countries’ obligations to the World Trade Organization, cooperation and consultation among the NAFTA members would seem crucial if they are to achieve greater integration in the agrifood sector. This article examines the opportunities and challenges facing the NAFTA members as they seek further integration in the agrifood sector.     

The rise and rise of IFRS: An examination of IFRS diffusion

We seek to understand the ever-increasing push towards the international harmonization of accounting standards and particularly the inexorable rise of standards produced by the International Accounting Standards Board (IASB). While the primary justifications for the increasing recognition given to these standards (IFRS) are economic, we question whether the empirical evidence to date has yielded convincing support for these arguments. We therefore offer an alternative explanation for the origin and diffusion of IFRS that incorporates social and political factors. Outsourcing the manufacture of accounting standards to a single private agency appears to be a rational, lower cost option – lowering both economic and political costs for individual states as long as they continue to retain residual decision rights with respect to the adoption of IFRS. However, such outsourcing must also be perceived to be legitimate. IFRS confer institutionalized legitimacy because they possess three characteristics required of a technology for global governance. These are sponsorship by powerful interest groups/regulators, internationality and plasticity. We therefore conclude that the widespread diffusion today of IFRS can at best be only partially explained as an economically rational phenomenon. Rather, the demand for legitimate action in the face of tightly coupled and complex global markets is at least equally important in generating support for IFRS.     

A survey on pickup and delivery problems

This paper is the first part of a comprehensive survey on pickup and delivery problems. Basically, two problem classes can be distinguished. The first class, discussed in this paper, deals with the transportation of goods from the depot to linehaul customers and from backhaul customers to the depot. This class is denoted as Vehicle Routing Problems with Backhauls (VRPB). Four subtypes can be considered, namely the Vehicle Routing Problem with Clustered Backhauls (VRPCB – all linehauls before backhauls), the Vehicle Routing Problem with Mixed linehauls and Backhauls (VRPMB – any sequence of linehauls and backhauls permitted), the Vehicle Routing Problem with Divisible Delivery and Pickup (VRPDDP – customers demanding delivery and pickup service can be visited twice), and the Vehicle Routing Problem with Simultaneous Delivery and Pickup (VRPSDP – customers demanding both services have to be visited exactly once). The second class, dealt with in the second part of this survey, refers to all those problems where goods are transported between pickup and delivery locations. These are the Pickup and Delivery Vehicle Routing Problem (PDVRP – unpaired pickup and delivery points), the classical Pickup and Delivery Problem (PDP – paired pickup and delivery points), and the Dial-A-Ride Problem (DARP – passenger transportation between paired pickup and delivery points and user inconvenience taken into consideration). Single as well as multi vehicle versions of the mathematical problem formulations are given for all four VRPB types, the corresponding exact, heuristic, and metaheuristic solution methods are discussed.      

Indian call centres and business process outsourcing: a study in union formation

In this exploratory study of union formation in the Indian call centre/business process outsourcing sector, the authors draw upon evidence from the first detailed survey of members of the recently formed UNITES, and from extensive interviews. This paper engages with mobilisation theory and analyses of trade union formation.
