Modelling purchase patterns on the basis of incomplete and biased consumer purchase diary and UPC panel data

This study proposes a new approach for the analysis and prediction of product class and brand purchase patterns. The approach is designed to specifically consider data consisting of incomplete and biased purchase histories that may result from diary or UPC panel samples. Alternative approaches are developed that are illustrated on the basis of actual panel diary data and statistical estimation procedures to describe and predict actual product class and brand purchase patterns. A sensitivity analysis demonstrates the potentially substantial errors that may result from the analysis of panel data in practice.     

An evaluation of Delphi

The literature concerning quantitative applications of the Delphi method is reviewed. No evidence was found to support the view that Delphi is more accurate than other judgment methods or that consensus in a Delphi is achieved by dissemination of information to all participants. Existing data suggest that consensus is achieved mainly by group pressure to conformity, mediated by the statistical group response that is fed back to all participants.     

Developing healthcare facilities for a changing environment

When approaching facility and real estate development, healthcare leaders should: Enhance clinical integration and ensure more patient-friendly facilities. Focus on a facility's business requirements and operating needs. Create a business plan that demonstrates how a project would help deliver better care at lower cost during a time of declining payment levels. Develop an approach that balances the needs of all stakeholders, including payers, staff, and patients.     

The relationship between brokers’ influence, strength of ties and NPD project outcomes in innovation-driven horizontal networks

This paper examines the impact of a broker's perceived use of power – position (i.e., coercive, reward and legitimate) and personal (i.e., expert, information and referent) – on strength of ties between network members and new product development (NPD) project outcomes. Our sample consists of 100 individuals drawn from 42 organizations that were involved in different innovation-driven horizontal networks. The results of structural equation modeling suggest that the perceived use of both personal power bases and position power bases by the broker are positively related to the strength of ties between members. Strength of ties, on the other hand, is positively related to NPD project outcomes of design performance and development time. Finally, results show that the relationships between a broker's use of different power bases and NPD project outcomes are fully mediated by the strength of ties between networks members. Implications for research, theory, and practice are discussed.     

欧元对美元：存在统治地位之争吗

经过了虚拟欧元三年的经验,以及在实际欧元问世的前夕,欧元事实上完全有可能挑战美元国际货币的地位。欧元面值债券的发行量已经超过美元面值债券的发行量。世界已经享有一个两极的国际金融市场,尽管还不是一个两极的国际货币体系。持有美元作为大量的国际储备使得这种货币在货币危机时变成瓮中之鳖,完全依赖于美元作为主要储备货币、发票货币、和干预货币带来了根本没有必要的风险。因此,欧元成为美元主要竞争者的时期即将到来。     

A Laddering Approach to the Use of Methods and Techniques to Reduce the Cycle Time of New-to-the-Firm Products

Millson, Raj, and Wilemon have developed the earliest extant knowledge on the implementation of methods and techniques to reduce new product development (NPD) cycle time by suggesting a hierarchy of generic NPD acceleration approaches. The purpose of this article is to extend Millson, Raj, and Wilemon's hierarchy by recasting and augmenting the conceptual basis of their hierarchy for new-to-the-firm products. Taking this hierarchy of generic NPD acceleration approaches as a starting point, the authors set out to form a number of generic NPD acceleration approaches by surveying the literature and conducting an experience survey with academics and managers. A logical and purposeful implementation sequence subsequently is established by using the laddering technique. The results indicate that managers make tradeoffs in NPD with regard to speed, development costs, and customer value, and that not all generic NPD acceleration approaches need to be implemented in order to obtain the greatest effectiveness. © 1999 Elsevier Science Inc.     

Case Studies of Farmers' Use of Information Systems

Exploratory case study research was initiated to study the evolution of management information systems and their use in operational and strategic decisions. The unit of analysis was the management team on farms with innovative or successful information systems. Human factors, such as an analytical nature and commitment to lifelong learning, were perceived to be the most important common elements. Production variables often were critical success factors. Managers annually developed financial statements; enterprise and "what if" analyses were conducted regularly. Learning about questions that innovative producers have difficulty addressing was time-consuming but instructive with respect to research and educational needs.     

A Multi-level Investigation of Authentic Leadership as an Antecedent of Helping Behavior

We develop and test a trickle-down model of how authentic leadership at the department level flows down the organizational hierarchy to encourage team leader authentic leadership and consequently, promotes team and individual-level supervisor-directed helping behavior. Analyses of multi-level and multi-source data collected from a total of 487 employees comprising 122 teams, 47 departments, and 4 different working areas of a major public sector organization in Taiwan show that team leaders’ authentic leadership mediates the relationship between departmental authentic leadership and individual-level leader–member exchange (LMX). We also found that intra-team trust completely mediates the influence of team authentic leadership on both team helping behavior and individual-level supervisor-directed helping behavior. Finally, the results reveal that self-concordance mediates the influence of team authentic leadership on individual-level supervisor helping behavior as well as the influence of individual-level LMX on individual-level supervisor-directed helping behavior. Theoretical and practical implications of these findings are discussed.     

Long‐term Determinants of Deforestation in Ghana: The Role of Structural Adjustment Policies

Abstract: Prior to the 1980s, Ghana witnessed an alternating cycle of boom and scarcity, culminating in the introduction of structural adjustment policies in the early 1980s. This paper uses data from the Ghana Forestry Services, Ministry of Food and Agriculture, FAO Yearbook of Forestry Products, Ghana Timber Marketing Board, Quarterly Digest of the Ghana Statistical Service, World Debt Tables, Bank of Ghana, IMF, COCOBOD and Ministry of Finance to examine the impact of SAP on deforestation in Ghana. The paper reveals a negative impact of structural adjustment on deforestation in Ghana through both direct and indirect channels. The most important channel of the effect of SAP on deforestation resulted from the conversion of forestland to crop farming, particularly cocoa farming, during the post‐adjustment period. Even though wood extraction exhibited a negative impact on deforestation, the impact seemed relatively weaker than that of agricultural land use. In addition, while in the long run, deforestation tended to be more responsive to logging than agriculture, in the short run the elasticity of deforestation with respect to agriculture tended to be greater than that with respect to logging. Finally, agriculture was relatively more important in causing deforestation.     

The effects of supplier capabilities on industrial customers’ loyalty: the role of dependence

This research examines whether suppliers’ capabilities impact OEM customers’ dependence on the supplier and thereby generate customer loyalty. Using a sample of purchasing managers focusing on a single key component supplier, we examine three supplier capabilities, two dependence dimensions, and three aspects of customer loyalty. Core offering capability increases the customer firm’s benefit-based dependence. Operations capability has a more comprehensive effect, enhancing both benefit-based and cost-based dependence. Benefit-based dependence leads to relational loyalty and, through its effect on relational loyalty, to insensitivity to competitive offerings and future purchase expansion. Cost-based dependence motivates insensitivity to competitive offerings, but does not affect relational loyalty or purchase expansion. The supplier’s communication capability is associated with relational loyalty, but this effect does not flow through the customer firm’s dependence. The divergent pattern of antecedents and effects of benefit-based dependence and cost-based dependence may explain the inconsistent and insignificant research findings in previous research on dependence. Our results suggest that adopting a bi-dimensional model of dependence more fully captures the theoretical domain of dependence, thereby permitting researchers to better examine its role in supply chain, channel, and marketing relationships.
