Comparing technology education in the U.S. and U.K.

British and American discourses and experiences with respect to technology education are compared. Out of this comparison important issues are identified that have implications for the larger ongoing conversation on technology beyond these countries. They include the role of the state in establishing and validating the subject, the dual claims of technology literacy and technological capability, and dual curricular approaches — content and process.     

Demand and supply integration: a conceptual framework of value creation through knowledge management

Strategy identifies two primary sets of processes through which the firm creates value for its customers by moving goods and information through marketing channels: demand-focused and supply-focused processes. Historically, firms have invested resources to develop a core differential advantage in one or other of these areas—but rarely in both—often resulting in mismatches between demand (what customers want) and supply (what is available in the marketplace). This paper suggests that successfully managing the supply chain to create customer value requires extensive integration between demand-focused processes and supply-focused processes that is based on a foundation of value creation through intraorganizational knowledge management. Integrating demand and supply processes helps firms prioritize and ensure fulfillment based upon the shared generation, dissemination, interpretation and application of real-time customer demand as well as ongoing supply capacity constraints. We draw upon literature in marketing, logistics, supply chain management and strategy to introduce a conceptual framework of demand and supply integration (DSI). We also offer insights for managerial practice and an agenda for future research in the relatively under-researched, but strategically important, area of demand and supply integration.     

Does mother nature punish rotten kids?

The theory of parent-offspring conflict predicts that mothers and their offspring may not agree about how resources should be allocated among family members. An offspring, for example, may favor a later weaning date than does its mother. Despite a parent's physical superiority, it may be that offspring are able to manipulate their parents' behavior. In this paper, we investigate a two-locus population genetic model of weaning conflict in which offspring can attempt to extort resources from their parents by reducing their own chances of survival if their demands are not met. We find that the frequency of recombination between the genes controlling maternal behavior and those controlling juvenile behavior determines the evolutionary outcome of this genetic conflict. When these genes are tightly linked, the mother will be able to get her way. When they are not, offspring can successfully 'blackmail' their parents into providing additional resources.     

A STRATEGIC FRAMEWORK FOR SUPPLY CHAIN ORIENTED LOGISTICS

The Council of Logistics Management's (CLM) name change to the Council of Supply Chain Management Professionals (CSCMP) has intensified discussions regarding the difference between supply chain management and logistics. This paper merges broadly accepted paradigms from strategic management and marketing to introduce a theoretically consistent framework that differentiates supply chain management from logistics while highlighting the complementary relationship. Supply chain management is portrayed as a firm or SBU level phenomena while logistics is expressed as a competency within supply chain management possessing both strategic and structural capabilities focused exclusively on managing the move/store activities used to fulfill customer orders. Research propositions regarding the interfaces and nature of logistics within a strategic supply chain orientation are drawn to guide thought and development in the discipline.     

Alliance Management: A View from the Past and a Look to the Future

The literature on strategic alliances has focused mainly on issues related to alliance formation and the reasons why firms form these partnerships. Yet the large number of failures would suggest that there exists a gap between an understanding of alliance formation and the practice of alliance management. The purpose of this paper is to narrow that gap. We begin with a review of the extant state-of-knowledge and then discuss areas in which further insight can be gained. More specifically, the remainder of the paper focuses on issues related to managing alliances over time and the role of the alliance manager, a linch-pin in the alliance management process.     

THE SURVIVAL ZONE FOR A BOND WITH BOTH CALL AND PUT OPTIONS EMBEDDED

We present a numerical method to price bonds that have multiple embedded options with an emphasis on the case with both long call and short put options. The valuation framework is a one-factor model for the term structure of interest rates, where the instantaneous interest rate is allowed to follow a fairly general stochastic process. The equilibrium interest rates that define the free boundaries for the embedded call and put options are given. We demonstrate the survival zone within which a bond with both long call and short put options remains afloat. We show that even moderate levels of transaction costs can have a significant effect on exercise of options.     

Risk and Return within the Single-Family Housing Market

The trade-off between risk and return in equity markets is well established. This paper examines the existence of the same trade-off in the single-family housing market. That market is dominated by homeowners, who constitute about two-thirds of U.S. households. For them the choice about how much housing and what house to buy is a joint consumption-investment decision. Furthermore, owner-occupied housing is by nature a lumpy investment whose risk cannot be completely diversified. Does this consumption-investment link negate the risk-return trade-off within the single-family housing market? Theory suggests the link still holds. This paper supplies empirical evidence in support of that theoretical result.     

Design and evaluation of road pricing: state-of-the-art and methodological advances

This article provides an in-depth review of the state-of-the-art and describes methodological advances in the design and evaluation of road network pricing schemes. A number of paradigm shifts from the two polar cases of the marginal social cost pricing of road traffic congestion and revenue-maximizing road toll pricing are analyzed, as induced by the need to address realistic design complexities and constraints. The crucial role of the joint consideration of pricing strategies with optimal capacity provision and several network management measures is manifested and an integrated evaluation framework is suggested to incorporate a wide range of road pricing impacts into the scheme design process.
