On building better construct measures: Implications of a general hierarchical model

Four problems occur in the scale development process: (a) defining the construct, (b) drawing items from multiple domains, (c) identifying dimensions, and (d) showing nomological validity. In order to minimize these problems, the authors propose a general hierarchical model (GHM) that provides an organizational structure for placing many of the individual difference constructs used in marketing and consumer behavior. Three principles, which were derived from the GHM, add to the current scale development paradigm: (a) Define and test the construct within a hierarchical network that includes antecedents and consequences, (b) define and test the construct's dimensionality, and (c) match the construct's items to its level in the hierarchical system. By using these steps in scale development, researchers can build more precise measures possessing higher levels of validity and reliability. © 2008 Wiley Periodicals, Inc.     

Best practice interventions: Short-term impact and long-term outcomes

This paper uses empirical field research to examine whether short-term best practice interventions (BPIs) can lead to improvements that are sustained in the long term. In addition, this research investigates the implied conflict between striving for short-term results and achieving long-term development of capabilities. It also examines the tension between the lack of resources of the typical small and medium sized enterprise (SME) users of BPIs and the time required to develop a critical mass of capability. A longitudinal case-based study of eight SME contexts examined BPI outcomes and factors leading to short- and long-term success and sustaining best practices. The research identifies factors related to the intervention context, implementation and change-agent approach. The data indicate that in resource-limited SMEs BPIs are limited in their ability to develop adequate capability for long-term change.     

Consumption and Wealth in Australia

This paper examines the relationship between consumption and wealth in Australia. We find a steady-state relationship between non-durables consumption, labour income and aggregate household wealth for the period 1988–1999. We also find that changes in both non-financial and financial assets have significant but different short-run and long-run effects in dynamic consumption models. Finally, we place our results within the broader empirical literature and examine whether they are consistent with standard theories of consumption.     

Multiple independent invention and the process of technological innovation

Multiple independent invention, i.e. two or more inventions being made independently of each other (not necessarily at the same time), is a well documented phenomenon. The concept is embodied in the phrase “reinventing the wheel” which is part of common knowledge, and widely used.Although the concept of multiple independent invention has been widely reported, it has rarely been recognised in the context of the process of technological innovation or the diffusion of innovations. In addition the majority of the studies of multiples have been well after the date of invention; little study has taken place of multiples during the subsequent innovation process. This article reports the study of one case of multiple independent innovation, examining the processes of innovation and diffusion in each identified version of the multiple. It tries to show how this concept provides new insights into the process of technological innovation.     

Significant Issues for the Future: Some Additional Perspectives

The rational elements of management dominated the questions raised by our Editorial Board members in the previous issue of JPIM when they offered their ideas in, "Significant Issues For the Future of Product Innovation." In this article, the discussion is continued with some other Board members but this time the human side of managements gets its due attention. The issues presented here add to the picture of complexity that is the reality of product innovation but they also may provoke the thinking that can lead to an improvement in management performance.     

Place,space, and foreign direct investment into peripheral cities

Perspectives drawn from the economic geography literature are increasingly used to generate insights into locational issues in international business. In this paper, we seek to integrate these literatures further by investigating the locational determinants of foreign direct investment (FDI) into peripheral cities within an emerging economy. Peripheral cities in emerging economies are attracting a growing proportion of global FDI flows, but the international business literature lacks a framework for understanding subnational determinants of FDI, particularly into non-core locations. We draw on the core-periphery model to build and test theory on how spatial interdependencies between subnational locations impact on the distribution of FDI inflows into a large and heterogeneous country China. Our results show that whilst peripheral cities tend to have a negative effect on FDI, this effect is positively moderated by proximity to core cities. The results highlight the importance of considering interactions between place and space when investigating locational issues in international business.     

Optimal Harvesting of an Age-Structured Schooling Fishery

Biologists have criticized traditional biomass models in fishery economics for being oversimplified. Biological stock assessment models are more sophisticated with regard to biological content, but rarely account for economic objectives. This study includes a full age-structured population model for studying schooling fisheries and extends the delayed difference approach used in earlier studies. We take the total harvest as the choice variable, resulting in a simple analytical structure. The model produces optimal steady states that may be higher or lower compared to the delayed-difference formulation. The model is applied to the Baltic sprat fishery. Both ecological and harvesting cost data support specifying Baltic sprat as a schooling fishery. Given nonlinear harvesting costs, the optimal solution is a path toward a steady state with smooth annual harvest and population age structure. Sensitivity analysis shows that the optimal solution is highly dependent on the population level of the sprat’s main predator Baltic cod. A linear cost function and an interest rate below 9 % imply pulse fishing instead of smooth continuous harvesting. Given nonlinear harvesting cost, the optimal steady state yield is rather insensitive to changes in the interest rate. However, under a high cod scenario, interest rates of 10 % or higher implies that no optimal steady state exists.     

Equality for women?

Many women still perceive men as their superiors in intellect. Although this double standard is dying, it is dying oh, so slowly.
