Competing Rationales for Corporate Governance in France: Institutional Complementarities between Financial Markets and Innovation Systems

CORPORATE GOVERNANCE, Issue 2 2008
Soo H. Lee
ABSTRACT Manuscript Type: Conceptual Research Question/Issue: This paper identifies the causes and consequences of corporate governance reform with reference to the French case. By disaggregating institutional complementarities into global and domestic dimensions, we analyze the path of institutional change compelled by financial efficiency and cooperative innovation. Research Findings/Results: Our analysis of the French case shows that both converging and diverging forces of institutional change coexist, shaping selective responses to globalization. While the adoption of the shareholder model is necessary for resource acquirement from the global capital markets, resource allocation in the cooperative innovation systems reinforces the stakeholder model. The French case confirms the sustainability of distinctive institutional complementarities, albeit with selective adaptation based on a sense-making social compromise. Theoretical Implications: The French case reminds us of the importance of distinctive institutional traditions and dominant social rationalities to understand the underlying logic of governance reform. The comparative research on corporate governance needs to address not just the cross-country variations in institutional arrangements and practices, but also the clash of competing rationales for reform explicitly in comparative terms within a single country context. Practical Implications: For foreign investors, it is vital to understand the unique institutional environment of state-centred stakeholder economies if they are to negotiate the best terms of return and to avoid unnecessary conflicts. French managers are expected to devise strategic choices responding to the competing rationales of governance. Managerial sense-making is essential for achieving sound long-term performance, upon which the legitimacy and sustainability of the constellation of selective governance rests. [source]

Integrating intelligent systems into marketing to support market segmentation decisions

INTELLIGENT SYSTEMS IN ACCOUNTING, FINANCE & MANAGEMENT, Issue 3 2006
Sally MckechnieArticle first published online: 13 MAR 200
For the last 50 years market segmentation has been considered to be a key concept in marketing strategy. As a means of tackling market heterogeneity, the underlying logic and managerial rationale for market segmentation is well established in the marketing literature. However, there is evidence to suggest that attempts by organizations to classify customers into distinct segments for whom product or services can be specifically tailored are proving to be difficult to implement in practice. As the business environment in which many organizations operate becomes increasingly uncertain and highly competitive, greater importance is now being attached to marketing knowledge. The purpose of this paper is to highlight market segmentation problems as a relevant area for a greater level of engagement of intelligent systems academic researchers and practitioners with their counterparts within the marketing discipline, in order to explore how data mining approaches can assist marketers in gaining valuable insights into patterns of consumer behaviour, which can then be used to inform market segmentation decision-making. Since the application of data mining within the marketing domain is only in its infancy, a research agenda is proposed to encourage greater interdisciplinary collaboration between information systems and marketing so that data mining can more noticeably enter the repertoire of analytical techniques being employed for segmentation.

Towards an automated deduction system for first-order possibilistic logic programming with fuzzy constants

INTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 9 2002
Teresa Alsinet
In this article, we present a first-order logic programming language for fuzzy reasoning under possibilistic uncertainty and poorly known information. Formulas are represented by a pair (,, ,), in which , is a first-order Horn clause or a query with fuzzy constants and regular predicates, and , , [0, 1] is a lower bound on the belief on , in terms of necessity measures. Since fuzzy constants can occur in the logic component of formulas, the truth value of formulas is many-valued instead of Boolean. Moreover, since we have to reason about the possibilistic uncertainty of formulas with fuzzy constants, belief states are modeled by normalized possibility distributions on a set of many-valued interpretations. In this framework, (1) we define a syntax and a semantics of the underlying logic; (2) we give a sound modus ponens-style calculus by derivation based on a semantic unification pattern of fuzzy constants; (3) we develop a directional fuzzy unification algorithm based on the distinction between general and specific object constants; and (4) we describe a backward first-order proof procedure oriented to queries that is based on the calculus of the language and the computation of the unification degree between fuzzy constants in terms of a necessity measure for fuzzy events. © 2002 Wiley Periodicals, Inc.

Compactness under constructive scrutiny

MLQ- MATHEMATICAL LOGIC QUARTERLY, Issue 6 2004
Hajime Ishihara
Abstract How are the various classically equivalent definitions of compactness for metric spaces constructively interrelated? This question is addressed with Bishop-style constructive mathematics as the basic system , that is, the underlying logic is the intuitionistic one enriched with the principle of dependent choices. Besides surveying today's knowledge, the consequences and equivalents of several sequential notions of compactness are investigated. For instance, we establish the perhaps unexpected constructive implication that every sequentially compact separable metric space is totally bounded. As a by-product, the fan theorem for detachable bars of the complete binary fan proves to be necessary for the unit interval possessing the Heine-Borel property for coverings by countably many possibly empty open balls.
