    Notes: The next generation Web Intelligence (WI) aims at enabling users to go beyond the existing online information search and knowledge queries functionalities and to gain, from the Web, practical wisdom for problem solving. To support such a Wisdom Web, we envision that a grid-like computing infrastructure with intelligent service agencies is needed, where these agencies can interact, self-organize, learn, and evolve their course of actions, identities, and interrelationships for new knowledge creation, as well as scientific and social evolution. In this paper, we first provide an overview of recent development in WI and Semantic/Knowledge Grid. Then, the fundamental capabilities of the Wisdom Web as well as the conceptual architecture of an intelligent Grid for supporting it are described. Technical challenges for realizing Grid Intelligence are highlighted and the recent advancements in related research areas are reviewed.

    Notes: A semantic link peer-to-peer (P2P) network specifies and manages semantic relationships between peers' data schemas and can be used as the semantic layer of a scalable Knowledge Grid. The proposed approach consists of an automatic semantic link discovery method, a tool for building and maintaining P2P semantic link networks (P2PSLNs), a semantic-based peer similarity measurement for efficient query routing, and the schema mapping algorithms for query reformulation and heterogeneous data integration. The proposed approach has three important aspects. First, it uses semantic links to enrich the relationships between peers' data schemas. Second, it considers not only nodes but also the XML structure in measuring the similarity between schemas to efficiently and accurately forward queries to relevant peers. Third, it copes with semantic and structural heterogeneity and data inconsistency so that peers can exchange and translate heterogeneous information within a uniform view.

    Notes: Despite high expectations, in The Netherlands the formation of public-private partnerships (PPPs) in the field of transport infrastructure is stagnating. This article addresses the question of why this is the case. On the basis of a comparative analysis of 9 case studies concerning the building of partnerships, 3 patterns are identified. The first is the successful formation of partnerships resulting in enriched projects. The second pattern is that of early interaction resulting in ambitious proposals for which there is no support. The third pattern shows ineffective market consultations followed by unilateral public planning, leading to stagnating contract negotiations.These patterns are coherent and are caused by a number of generic factors. An important explanation for stagnation is the lack of interaction. As a result, public and private parties will fail to reach a common understanding, will be unable to contribute to the enrichment of the project content and will fail to develop mutual trust. If parties engage in early interaction, the lack of embeddedness of their efforts may result in an uncritical piling up of ambitions and an absence of the capability to realize trade-offs and generate support. These explanations are related to the absence of conscious and systematic attempts to manage and arrange interaction processes aimed at the formation of PPPs. On the basis of these findings the author formulates a number of suggestions to improve the quality and effectiveness of these processes.

    Notes: In the career civil service the US federal government has long been guided by a merit system. This article traces how the principle of merit in appointment and promotion has developed since the nineteenth century and examines contemporary applications of competency frameworks in the US – their development, character, strengths and weaknesses. If core competency discussions and frameworks are to have a broader impact at both the government wide and the agency level, the frameworks will have to be disentangled. Existing notions of competencies for the political appointees, the leadership echelons of the career service, the rest of the career service, the entire government, central agencies, individual agencies, and badly needed future leaders not only suggest superhuman abilities, but also contain seriously conflicting expectations.

    Notes: Since its election in May 1997, the Labour Government in the United Kingdom has emphasized the need for modernization in the improvement of public services. For local government, this emphasis has led to the introduction of a variety of measures intended, primarily, to improve political management and service delivery. Two key policies have been the introduction of Best Value and the Comprehensive Performance Assessment (CPA). CPA is used by the Audit Commission for measuring local authority performance in England and has led to each authority being classified as excellent, good, fair, weak or poor. Each authority's classification has implications, financially and in terms of its freedom to determine priorities and policies. In addition, the structure of local government is being reviewed by central government, alongside discussions as to the merits of establishing regional assemblies. In considering the justification for, and the impact of, changes, it is important to consider the views of local government employees, not least professional groupings and chief officers. This paper reports the findings of a national survey of chief financial officers (CFOs) of the single tier and county council local authorities in England to establish their views on key features of the Government's modernization agenda.

    Notes: Path dependency is an important notion in diachronic approaches to understanding social and political processes. The first section of this paper examines the application of path dependency to policy studies; the advantages of the concept in understanding policy development are highlighted by examples from pension policy and social housing policy in the UK, and the EU budget. The next section considers several criticisms of path dependency: (1) it is a fashionable label for the intuition that ‘history matters’ without a clear and convincing account of decision-making over time; (2) it explains only stability and not change; (3) its normative implications are confused and mostly left unexplored. The final section concludes that path dependency, despite being theoretically inchoate and difficult to operationalize empirically, is a valid and useful concept for policy studies. However, its proper application demands sensitivity from scholars to other temporal dynamics that may operate in policy development.

    Notes: Research on the governance of publicly funded research does not recognize that social science and ‘science’ are distinct activities. Neither does it recognize that regulating research policy in purely science and technology terms has undesirable consequences for the social sciences – intended or otherwise. This paper seeks to correct these omissions and considers the governance of social science through the example of regulating ‘everyday epistemology’ at the science policy level. The British research council system is used in order to demonstrate how social science has been politically constructed as a legitimate enterprise for public funding. We find that social science is in fact regulated by non-social scientists. The result is that social science, seen as a square peg, is forced into the round hole of natural scientific thinking. When this policy is translated into governance structures it creates a ‘slave social science’ and subverts the role of social science as social science.

    Notes: Central government in the UK has introduced performance management regimes that apply rewards and sanctions to local service providers. These regimes assume that organizational performance is attributable to decisions made by local policy-makers rather than circumstances beyond their control. We test this assumption by developing a statistical model of external constraints on service standards and applying this model to the outcomes of comprehensive performance assessment (CPA) in English local government. The results show that CPA scores were significantly influenced by the characteristics – such as social diversity and economic prosperity – of local populations. Thus ‘poor’ performance is partly attributable to difficult circumstances rather than bad choices.

    Notes: This paper, which is based on recent field research, suggests an interpretative model of territorial government in France. Relations between national and local authorities as well as policy- making processes suggest that the centralized state has faced a major decline of its hegemony and that decentralization reforms have induced a polycentric dynamic. Seven basic characteristics and three key properties of the model are discussed. The emerging model fits neither a new localism nor a new centralist pattern. It is the product of ongoing and incremental trade-offs between centrifugal and centripetal rationales. This complexity reflects a situation that is under the rather conservative, as well as tight, control of national politicians who hold multiple local elected mandates.

    Notes: The theoretical and empirical analysis of administrative activities has been an important area of research since the establishment of political science as an academic discipline in Germany at the end of the 1960s. But is administrative science still a significant part of political science in Germany today? I argue here that in Germany a political science oriented administrative science has developed from a science focused on public administration, that is, on organizational questions, to one focused on public policies and thus on questions concerning the conditions and consequences of political problem solving and control (Steuerung). The question of the internal organization of government is increasingly regarded as an irrelevant one; in addition, the institutional promotion and funding of political science administration research has dramatically decreased since the 1970s. Today's new challenges (economization and internationalization) for both government and public administration seem to exceed the capability of political science administrative research. These challenges open up new opportunities, however, since, in the search for solutions beyond the dichotomy of market/managerialism on the one hand and traditional bureaucracy and state government on the other, political science in particular regains more importance. As will be shown, there are now tendencies which indicate that political science administrative research might encounter a stronger political demand. If the consequent research is able to find a new mixture of theory and practice, this in turn could help revitalize political science administrative research in Germany.

    Notes: The current UK government is committed to extending participation in civil society, with the aim of significantly increasing volunteer numbers by 2005. It has put much effort into attracting ‘representative participants’, particularly from traditionally under-represented groups. ‘Natural joiners’ attract far less interest and are often written off as ‘the same old faces’. But the growth in opportunities for participation has actually encouraged the natural joiners because the nature of much modern participation requires people like them. Focusing on natural joiners and their motivations rather than looking at why the non-joiners don’t join, should increase understanding of why people participate and suggest new ways forward. This article looks at people active in tenant participation – a case study of a government ‘Sounding Board’ and some preliminary results of a survey of activists. There are some unexpected findings, including that the motivations of natural joiners are close to those of career professionals in the same field, and that interest in the ‘subject’ of participation may be a motivator, rather than an outcome.

    Notes: While the notion of governance has received considerable scholarly attention, much less is known about change, and its sources, across modes of governance within respective policy domains. This article explores these neglected issues in two policy domains characterized by multi-level governance characteristics: Land (state)-local relationships in the domain of building administration and relationships governing the prisons domain in Germany. It does so in three steps. First, the article explores governance and considers endogenous and exogenous sources of change. Second, it discusses the institutional arrangements in the two domains and analyses modes of governance and their change. Third, the article compares the different dynamics of change and links these findings to wider debates regarding change across and within modes of governance. The analysis of the two domains suggests that ‘hunting around’ effects (i.e. permanent instability) are less prominent than suggested by cultural theory, while external pressures for change are filtered by the preferences of the actors within the respective domains.

    Notes: The tension between the goals of integrated, seamless public services, requiring more extensive data sharing, and of privacy protection, now represents a major challenge for UK policy-makers, regulators and service managers. In Part I of this article (see Public Administration volume 83, number 1, pp. 111–33), we showed that attempts to manage this tension are being made at two levels. First, a settlement is being attempted at the level of general data protection law and the rules that govern data-sharing practices across the public sector. We refer to this as the horizontal dimension of the governance of data sharing and privacy. Secondly, settlements are also being attempted within particular fields of public policy and service delivery; this we refer to as the vertical dimension.In this second part, we enquire whether risks to privacy are greater in some policy sectors than others. We do this, first by showing how the Labour Government's policy agenda is producing stronger imperatives towards data sharing than was the case under previous administrations in three fields of public policy and services, and by examining the safeguards introduced in these fields. We then compare the settlements emerging from differing practices within each of these policy sectors, before briefly assessing which, if any, principles of data protection seem to be most at risk and in which policy contexts. Four strategies for the governance of data sharing and privacy are recapitulated – namely, seeking to make the two commitments consistent or even mutually reinforcing; mitigating the tensions with safeguards such as detailed guidelines; allowing privacy to take precedence over integration; and allowing data sharing to take precedence over privacy. We argue that the UK government has increasingly sought to pursue the second strategy and that the vertical dimension is, in practice, much more important in defining the settlement between data sharing and privacy than is the horizontal dimension. This strategy is, however, potentially unstable and may not be sustainable. The conclusion proposes a radical recasting of the way in which the idea of a ‘balance’ between privacy and data-sharing imperatives is conceived.

    Notes: This paper uses the concept of path dependency to examine the changes to the political management structures of English local government. We note how the possible experience of decreasing returns among some local authority actors combined with the powerful intervention of politicians within New Labour at the national level led to a significant break from past policy and the imposition of measures to establish a separate executive that was claimed as a radical step forward for local democracy. Using survey data from the Evaluating Local Governance research team (), we explore the establishment of a separate political executive in all major local authorities and map out the style of decision-making that is emerging. We find that some established institutional patterns reasserted themselves in the process of implementation, but that increasing returns are not as great as some theorists of path dependency would suggest and they may be a force for system change as well as for stability.

    Notes: This paper is concerned with how administrators in the Housing Benefit (HB) service in Great Britain have reacted to the discretionary powers given to local authorities as a result of the introduction of Discretionary Housing Payments (DHPs). DHPs can be awarded to HB claimants deemed to require additional assistance with their housing costs. The paper first argues that the HB service can be categorized as ‘rule-bound’ before outlining the DHP regime and the nature of the discretion that it affords HB administrators. A brief review of the literature on discretionary decision making in public service organizations suggests four propositions in respect of DHP decision making. The paper then seeks to test these propositions. It concludes that in general HB administrators do not appear to have experienced the difficulties associated with discretionary decision making in rule-bound services that might have been expected on the basis of previous work in this field.

    Notes: In order to examine institutional change in Republic of Ireland (hereinafter referred to as ‘Ireland’ or ‘the Irish case’) as a consequence of European integration, this article looks at the adaptation of national institutions subsequent to EU membership. A new institutionalist approach is taken towards the definition and discussion of institutions in order that the analysis may encompass the broadest range of changes consequent to EU membership: in relation to national structures; decision-making patterns; socialization processes; and overall ‘system change’. The analysis uses the organizing concepts offered by Bulmer and Burch (1998) in their evaluation of the impact of Europeanization on national systems of public administration in Britain. According to this framework, ‘institutions can be analysed in terms of four gradations moving from the formal, through the informal, to the normative and cultural’ (Bulmer and Burch 1998, p. 604).

    Notes: The question can be raised whether the principal effect of interactive policy development is to shore up a (creaking) democratic system or to destabilize its very foundations. In this article, a framework is presented for assessing the democratic credentials of interactive policy development. It is based on four views on how a democracy should work: instrumental or substantial democracy and direct or indirect democracy. Critics and advocates differ in their confidence that the intended aims can ever be realized. Based on extensive case study material of interactive local policy development projects collected between 1997 and 2001, the validity of the various arguments for or against interactive policy-making is analysed. The analysis indicates that whether interactive policy development undermines or sustains democracy depends principally on the extent to which divergences in the expectations of the various groups are made explicit and unrealistic or mistaken expectations are dispelled.

    Notes: Now that it is widely accepted that the European Union (EU) constitutes a system of governance, analysts need actively to explore precisely how it may affect the continuing struggle better to coordinate national and European administrations. In its 2001 White Paper on governance, the European Commission interpreted governance to mean less central control and more network-led steering. Its interpretation of such networks is that they are self-organizing. Drawing upon an empirical study of environmental policy integration (EPI) in the EU, this article shows that this vision may not adequately fit the multi-actor, multi-level coordination challenges associated with some EU problems. By studying the administrative capacities that the European Commission and three member states have created to achieve better environmental coordination, this article shows significant administrative weaknesses. It concludes that the coordination challenges now troubling the EU require a more thoughtful discussion of network management than the White Paper suggests.

    Notes: Competition was one of the guiding threads of public policy under the Conservative Governments of the 1980s and 1990s. But whereas the Conservatives looked to the market primarily for the disciplining and economizing effects of competition, the Labour Government sees the market as a source of innovation and improvement. Following a brief description of these different perspectives, this paper identifies three avenues deserving of further inquiry: the costs and benefits of high trust interorganizational relationships; the way in which partnerships combine the competencies of different sectors; and finally, the extent to which the new partnerships transform public service delivery.

    Notes: Abstract: An optimal online learning algorithm of a wavelet neural network is proposed. The algorithm provides not only the tuning of synaptic weights in real time, but also the tuning of dilation and translation factors of daughter wavelets. The algorithm has both tracking and smoothing properties, so the wavelet networks trained with this algorithm can be efficiently used for prediction, filtering, compression and classification of various non-stationary noisy signals.

    Notes: Abstract: Owing to rapidly changing customer needs and much shorter product life cycles, for developing a successful product it is imperative to employ more efficient and flexible approaches for product conceptualization. To meet this demand, a Web-enabled product definition and customization system (PDCS) is proposed, from a design-knowledge-handling viewpoint, in this paper. It comprises two phases, namely product definition based on the laddering technique and a novel design knowledge hierarchy, and product customization based on an integrated methodology of conjoint analysis and Kohonen association techniques. Basically, this system is a method of conducting design decision-making via customer involvement, i.e. a strategy for transforming customer preference into a specific product concept. A case study on wood golf club design is used to illustrate and validate the proposed Web-enabled PDCS.

    Notes: Abstract: This paper describes the development and tuning methods for a novel self-organizing fuzzy proportional integral derivative (PID) controller. Before applying fuzzy logic, the PID gains are tuned using a conventional tuning method. At supervisory level, fuzzy logic readjusts the PID gains online. In the first tuning method, fuzzy logic at the supervisory level readjusts the three PID gains during the system operation. In the second tuning method, fuzzy logic only readjusts the proportional PID gain, and the corresponding integral and derivative gains are readjusted using the Ziegler–Nichols tuning method while the system is in operation. For the compositional rule of inferences in the fuzzy PID and the self-organizing fuzzy PID schemes two new approaches are introduced: the min implication function with the mean of maxima defuzzification method, and the max-product implication function with the centre of gravity defuzzification method. The fuzzy PID controller, the self-organizing fuzzy PID controller and the PID controller are all applied to a non-linear revolute-joint robot arm for step input and path tracking experiments using computer simulation. For the step input and path tracking experiments, the novel self-organizing fuzzy PID controller produces a better output response than the fuzzy PID controller; and in turn both controllers exhibit better process output than the PID controller.

    Notes: Abstract: Customer retention is a critical issue for the survival of any business in today's competitive marketplace. In this paper, we propose a dynamic procedure utilizing self-organizing maps and a Markov process for detecting and preventing customer defection that uses data of past and current customer behavior. The basic concept originates from empirical observations that identified that a customer has a tendency to change behavior (i.e. trim-out usage volumes) before eventual withdrawal and defection. Our explanatory model predicts when potential defectors are likely to withdraw. Two strategies are suggested to respond to the question of where to lead potential defectors for the next stage, based on anticipating when the potential defector will leave. Our model predicts potential defectors with little deterioration of prediction accuracy compared with that of the multilayer perceptron neural network and decision trees. Moreover, it performs reasonably well in a controlled experiment using an online game.

    Notes: Abstract: Logistics service providers are professionals who serve clients such as manufacturers, raw material suppliers, distributors, retailers and shippers within the supply chain. Traditionally, the formulation of logistics strategies to execute various logistics services has been based solely on experience. In this paper, an intelligent case-based logistics strategy system (CLSS) is designed to help logistics service providers to develop strategies under various customers' demands. The proposed system, which is suitable for use in warehouse operations in the Hong Kong/Pearl River Delta region, enhances the effectiveness of logistics strategies formulations by integrating case-based reasoning technology seamlessly with various data management software such as a data warehouse, on-line analytical processing and a multidimensional database management system. Through applying CLSS in Eastern Worldwide Company, the resource utilization is maximized while work efficiency is greatly enhanced. As a result, the overall logistics operations are smoothened significantly.

    Notes: Abstract: Understanding and adapting to changes in customer behavior is an important aspect for survival in a continuously changing environment. This paper develops a methodology based on decision tree analysis to detect the change in classified customer segments automatically between two data sets collected over time. We first define three types of changes as the emerging pattern, the unexpected change and the added/perished rule. Then, similarity and difference measures are developed for rule matching to detect all types of change. Finally, the degree of change is developed to evaluate the amount of change. Our suggested methodology based on decision tree analysis in the change detection problem can be used in more structured situations in which the manager has a specific research question and it also detects the change of classification criteria in a dynamically changing environment. A Korean Internet shopping mall case is evaluated to represent the performance of our suggested methodology, and practical business implications for this methodology are also provided. We believe that the change detection problem and the suggested methodology will become increasingly important as more data mining applications are implemented.

    Notes: Abstract: Decision tree induction has been widely studied and applied. In safety applications, such as determining whether a chemical process is safe or whether a person has a medical condition, the cost of misclassification in one of the classes is significantly higher than in the other class. Several authors have tackled this problem by developing cost-sensitive decision tree learning algorithms or have suggested ways of changing the distribution of training examples to bias the decision tree learning process so as to take account of costs. A prerequisite for applying such algorithms is the availability of costs of misclassification. Although this may be possible for some applications, obtaining reasonable estimates of costs of misclassification is not easy in the area of safety.This paper presents a new algorithm for applications where the cost of misclassifications cannot be quantified, although the cost of misclassification in one class is known to be significantly higher than in another class. The algorithm utilizes linear discriminant analysis to identify oblique relationships between continuous attributes and then carries out an appropriate modification to ensure that the resulting tree errs on the side of safety. The algorithm is evaluated with respect to one of the best known cost-sensitive algorithms (ICET), a well-known oblique decision tree algorithm (OC1) and an algorithm that utilizes robust linear programming.

    Notes: Abstract: Although sorting techniques (e.g. card sorts) are widely used in knowledge acquisition and requirements acquisition, they have received little formal attention compared to related techniques such as repertory grids and laddering. This paper briefly describes the main sorting techniques, and then provides a detailed tutorial on one variety (repeated single-criterion sorts), using a worked example. Guidelines for choice and sequencing of techniques are given, both in relation to varieties of sorting technique and in relation to other techniques. It is concluded that the sorting techniques are a valuable part of the elicitor's methodological toolkit.

    Notes: Abstract: Among the knowledge elicitation techniques card sorting is notable for its simplicity of use, its focus on subjects' terminology (rather than that of external experts) and its ability to elicit semi-tacit knowledge. Card sorting involves categorizing a set of pictures, objects or labelled cards into distinct groups using a single criterion. This paper focuses on the challenges associated with analyzing the data that result from card sorts, especially when large data sets are generated. Traditional semantic analysis methods that require direct researcher interpretation of elicited linguistic terms are distinguished from methods that are purely syntactic, and hence can be automated. Each paper within this special issue is summarized and its contribution to card sorting in general, and data analysis in particular, is highlighted. The set of novel computational techniques presented in several of the papers in this issue is examined. The paper concludes by noting that even large-scale data sets can be meaningfully analysed by combining well-known interpretative methods with the new computational approaches presented within this special issue.

    Notes: Abstract: Web page design guidelines produce a pressure towards uniformity; excessive uniformity lays a Web page designer open to accusations of plagiarism. In the past, assessment of similarity between visual products such as Web pages has involved an uncomfortably high degree of subjectivity. This paper describes a method for measuring perceived similarity of visual products which avoids previous problems with subjectivity, and which makes it possible to pool results from respondents without the need for intermediate coding. This method is based on co-occurrence matrices derived from card sorts. It can also be applied to other areas of software development, such as systems analysis and market research.

    Notes: Abstract: Picture sorts were used to investigate perceptions of women's office clothes, with a sample of ten male and ten female subjects who normally worked in an office environment. The pictures on the cards were taken from catalogues, and showed women's outfits which might be worn in an office. The subjects sorted the cards repeatedly and generated criteria and categories of their own choice. Some of the criteria and categories had not been previously reported in the clothing research literature. Over half of the male subjects, but none of the female subjects, used ‘married/unmarried woman’ as a sorting criterion, although only one of the images sorted showed a wedding ring. A significantly higher proportion of male than of female subjects used dichotomous categorization (i.e. sorting the cards into two piles for one or more of the criteria). The reasons for this are obscure, but do not appear to be a simple outcome of males not knowing much about female clothing. Previous research into clothing has tended to involve researcher-centred approaches such as semiotics; the results from this study suggest that there would be advantages in wider use of subject-centred approaches such as card sorts, both in this domain and elsewhere. It was concluded that card sorts were a useful method and should be more widely used.

    Notes: Abstract: Card sorts are a knowledge elicitation technique in which participants are given a collection of items and are asked to partition them into groups based on their own criteria. Information about the participant's knowledge structure is inferred from the groups formed and the names used to describe the groups through various methods ranging from simple quantitative statistical measures (e.g. co-occurrence frequencies) to complex qualitative methods (e.g. content analysis on the group names). This paper introduces a new technique for analyzing card sort data that uses quantitative measures to discover rich qualitative results. This method is based upon a distance metric between sorts that allows one to measure the similarity of groupings and then look for clusters of closely related sorts across individuals. By using software for computing these clusters, it is possible to identify common concepts across individuals, despite the use of different terminology.

    Notes: Abstract: Card sorts can be used to study the way human subjects acquire and organize conceptual knowledge. Analyses of card sorts often involve subjective examination of criteria or category names or using clustering techniques, neither of which lend themselves well to direct statistical analysis. This paper defines NMST, a quantitative measure of knowledge discrimination based on repeated, single-criterion card sorts that is independent of criteria or category names and that is particularly amenable to statistical analysis. The NMST measure is illustrated by applying it to a particular data set collected in a large multinational card sort study of subjects, where the knowledge area comes from a first-year programming course. Applied to this data set, the NMST measure is shown to distinguish, with statistical significance, between a set of subjects with only an introduction to programming and a set of subjects who have completed the equivalent of a bachelor's degree or higher in a computing-related discipline.

    Notes: Abstract: This paper presents a case study of the use of a repeated single-criterion card sort with an unusually large, diverse participant group. The study, whose goal was to elicit novice programmers' knowledge of programming concepts, involved over 20 researchers from four continents and 276 participants drawn from 20 different institutions. In this paper we present the design of the study and the unexpected result that there were few discernible systematic differences in the population. The study was one of the activities of the National Science Foundation funded Bootstrapping Research in Computer Science Education project (2003).

    Notes: Abstract: This paper describes a multi-institutional study that used a repeated single-criterion card sort to investigate graduating computer science students' knowledge of programming concepts. The study seeks to improve computer science instruction by gaining insight into how graduating students retain and assimilate introductory programming knowledge into their broader understanding of the discipline. A total of 291 card sorts was elicited from 65 undergraduate students in their final year of study at eight colleges and universities throughout the USA. To fully exploit the rich qualitative and quantitative aspects of the card sort data, an integrative analysis process was used that combined content analysis with two measures, normalized minimum spanning tree and edit distance, both developed specifically to analyze card sort data.

    Notes: Abstract: Administrative knowledge or office knowledge is the knowledge used in conjunction with the support operations in an organization. Systems managing this knowledge are referred to as extended office systems (EOSs). EOSs will be used to support knowledge exchanges in organizations. The types of knowledge handled by EOSs are illustrated and their characteristics are highlighted. Based on these characteristics, a formalism is proposed, which utilizes structural and descriptive links to achieve an extensible, open-ended representation. A prototype system using the representation and incorporating approximately 200 items of knowledge has been developed and can answer questions about a software engineering company.

    Notes: Abstract: In this study a wavelet-based neural network model, employing the multilayer perceptron, is presented for the detection of electrocardiographic changes in patients with partial epilepsy. Decision making is performed in two stages: feature extraction using the wavelet transform, and multilayer perceptron neural networks (MLPNNs) trained with the backpropagation, delta-bar-delta, extended delta-bar-delta and quick propagation algorithms as classifiers. The classification results, the values of statistical parameters and performance evaluation parameters of the MLPNNs trained with different algorithms are compared. Two types of electrocardiogram beats (normal and partial epilepsy) obtained from the MIT-BIH database were classified with accuracy varying from 90.00% to 97.50% by the MLPNNs trained with different algorithms.

    Notes: Abstract: The ship design process is a highly data-oriented, dynamic, iterative and multi-stage algorithm. It utilizes multiple abstraction levels and concurrent engineering techniques. Specialized techniques for knowledge acquisition, knowledge representation and reasoning must be developed to solve these problems for a ship design expert system. Consequently, very few attempts have been made to model the ship design process using an expert system approach. The current work investigates a knowledge representation–reasoning technique for such a purpose. A knowledge-based conceptual design was developed by utilizing a prototype approach and hierarchical decompositioning. An expert system program called ALDES (accommodation layout design expert system) was developed by using the CLIPS expert system shell and an object-oriented user interface. The reasoning and knowledge representation methods of ALDES are explained in the paper. An application of the method is given for the general arrangement design of a containership.

    Notes: Abstract: It is estimated that 4.6 billion tons of non-hazardous solid waste materials are produced annually in the USA. The potential reuse for a portion of the materials in the construction of highways and roads suggests that valuable benefits in terms of economic and environmental gains are possible. This paper describes the development of a prototype computer-assisted tool or expert system to help manufacturers assess and analyze their industrial residuals as potential road construction material. This represents an expansion in the application of intelligent systems to domains where a few, hard-to-find technical reports have represented the main source of expertise available to practitioners for years. The system, developed through the use of an object-oriented software shell, Level5 Object, was designed in a user-friendly Windows environment which allows users with little or no computer training to effectively evaluate material residuals.

    Notes: Abstract: We present a new architecture of a diagnostic system composed of an associative memory with feedback connections. This new architecture requires limited computer resources, it is fast, and it can run on small computers. The diagnostic process is described by a deduction system that performs an abductive inference. The abductive inference itself is explained by the verbal category theory. We model both processes by an associative memory that performs the inference with the aid of the feedback connections. The represented knowledge is arranged in groups that define taxonomy. An embedded diagnostic system for the determination of a disorder with applications in modern industrial machines is presented.

    Notes: Abstract: To cope with the requirements of high dimensional accuracy for injection molding components, it is important to optimize the process parameters in order to sustain the high level dimensional quality of the molded parts. In this respect, a study in the domain of process optimization is of paramount importance in terms of determining the optimal set of injection molding parameters. To this end, a methodology to establish an integrated model which consists of both fuzzy logic reasoning and a genetic algorithm is proposed. These two artificial intelligence techniques can complement each other to form an integrated model which capitalizes on the merits and at the same time offsets the pitfalls of the involved technologies. To validate the feasibility of the proposed model, a case study related to injection molding optimization is also covered in this paper.

    Notes: Autonomous agents that learn about their environment can be divided into two broad classes. One class of existing learners, reinforcement learners, typically employ weak learning methods to directly modify an agent's execution knowledge. These systems are robust in dynamic and complex environments but generally do not support planning or the pursuit of multiple goals. In contrast, symbolic theory revision systems learn declarative planning knowledge that allows them to pursue multiple goals in large state spaces, but these approaches are generally only applicable to fully sensed, deterministic environments with no exogenous events. This research investigates the hypothesis that by limiting an agent to procedural access to symbolic planning knowledge, the agent can combine the powerful, knowledge-intensive learning performance of the theory revision systems with the robust performance in complex environments of the reinforcement learners. The system, IMPROV, uses an expressive knowledge representation so that it can learn complex actions that produce conditional or sequential effects over time. By developing learning methods that only require limited procedural access to the agent's knowledge, IMPROV's learning remains tractable as the agent's knowledge is scaled to large problems. IMPROV learns to correct operator precondition and effect knowledge in complex environments that include such properties as noise, multiple agents and time-critical tasks, and demonstrates a general learning method that can be easily strengthened through the addition of many different kinds of knowledge.

    Notes: This paper describes Eureka, a problem-solving architecture that operates under strong constraints on its memory and processes. Most significantly, Eureka does not assume free access to its entire long-term memory. That is, failures in problem solving may arise not only from missing knowledge, but from the (possibly temporary) inability to retrieve appropriate existing knowledge from memory. Additionally, the architecture does not include systematic backtracking to recover from fruitless search paths. These constraints significantly impact Eureka's design. Humans are also subject to such constraints, but are able to overcome them to solve problems effectively. In Eureka's design, we have attempted to minimize the number of additional architectural commitments, while staying faithful to the memory constraints. Even under such minimal commitments, Eureka provides a qualitative account of the primary types of learning reported in the literature on human problem solving. Further commitments to the architecture would refine the details in the model, but the approach we have taken de-emphasizes highly detailed modeling to get at general root causes of the observed regularities. Making minimal additional commitments to Eureka's design strengthens the case that many regularities in human learning and problem solving are entailments of the need to handle imperfect memory.

    Notes: In this paper we propose a distributed knowledge management framework for semantics and knowledge creation, population, and reuse on the grid. Its objective is to evolve the Grid toward the Semantic Grid with the ultimate purpose of facilitating problem solving in e-Science. The framework uses ontology as the conceptual backbone and adopts the service-oriented computing paradigm for information- and knowledge-level computation. We further present a semantics-based approach to problem solving, which exploits the rich semantic information of grid resource descriptions for resource discovery, instantiation, and composition. The framework and approach has been applied to a UK e-Science project—Grid Enabled Engineering Design Search and Optimisation in Engineering (GEODISE). An ontology-enabled problem solving environment (PSE) has been developed in GEODISE to leverage the semantic content of GEODISE resources and the Semantic Grid infrastructure for engineering design. Implementation and initial experimental results are reported.

    Notes: The expressive power of XML Declarative Description (XDD), a unified XML-based representation language for the Knowledge Grid, is enhanced by a well-defined mechanism for modeling arbitrary XML first-order logical constraints (FLCs)—a special kind of constraints comprising XML expressions and logical symbols. The resulting knowledge representation can uniformly express explicit and implicit information, ontologies, axioms as well as integrity, structural and FLCs. It facilitates direct use of ordinary XML elements as its basic language component and semantic units, and formally defines XML clauses for modeling advanced complex statements. It achieves sound, efficient, and flexible computation or inference by means of the Equivalent Transformation (ET) paradigm—a new computational model based on semantic preserving transformations. Basic ET computational rules for reasoning with XDD descriptions with FLCs are also presented. Due to its well-founded mechanism and expressiveness, employment of the proposed representation and computation framework to model a knowledge grid and its services not only enables direct representation of knowledge bases described by such emerging Semantic Web ontology languages as RDF(S) and OWL, but also offers additional descriptive facilities by allowing expression of and reasoning with rules, relationships, and constraints. Moreover, in order to provide machine-interpretable descriptions of knowledge grid services, standard service description languages, e.g., WSDL, UDDI, OWL-S and WSMO are employed and extended with facilities to define additional service relationships, constraints, and composition rules.

    Notes: The paper addresses the problem of finding a compact representation of the diagnoses within a model-based approach to diagnosis. To this end, we introduce the notion of scenario, a special kind of CNF formula over the component variables, which can be used to encode a large number of diagnoses using the same amount of space needed for encoding just a single diagnosis. We show how the solutions to a diagnostic problem can be computed as sets of scenarios by presenting first an exhaustive algorithm and then an efficient algorithm, which exploits probabilistic information to restrict the result set to preferred scenarios. Finally, we discuss the issue of how to efficiently extract preferred diagnoses from sets of scenarios and characterize a class of system models for which our techniques perform particularly well. Concepts and algorithms introduced in the paper have been tested within the prototype of the diagnostic agent of a space robotic arm; resulting statistics are reported and critically discussed.

    Notes: In this paper we develop an integrated approach towards corporate governance and business ethics. Our central argument is that organisations can learn from the development of strategic planning in the 1970s and 1980s. We identify three weaknesses – a bureaucratic and formalised approach, lack of implementation and lack of integration throughout the organisation – which were prevalent in strategic planning in the past and which are potentially just as problematic for an integrated corporate governance approach to business ethics. We suggest ways these weaknesses might be avoided and provide questions for boards of directors to consider when integrating ethical concerns into their organisations’ corporate governance structures.

    Notes: This paper analyses recent corporate governance codes issued by 20 countries for evidence of convergence in corporate governance systems in Europe. The analysis shows that there has been a degree of convergence towards an Anglo-Saxon model of corporate governance as the audit committee concept is widely accepted in countries with both unitary and two-tier governance systems. Further, the latest audit committee recommendations in countries that have issued several governance codes show a strengthening of the recommendations for an audit committee over time in line with the Anglo-Saxon audit committee concept and convergence with the debate in the US and UK on issues such as the independence and financial expertise of members. However, consistent with the literature on the convergence of European corporate governance systems, at an operational level there is limited consistency in the recommended structure and role of audit committees.

    Notes: We analyse the relationship between firm value, as measured by Tobin's q, and newly released indices of effective corporate governance for a sample of 263 Canadian firms. The results indicate that corporate governance does matter in Canada. However, not all elements of measured governance are important, and the effects of governance do differ by ownership category. For the entire sample of firms we find no evidence that a total governance index affects firm performance. This is mainly because we find no evidence that board independence, the most heavily-weighted sub-index, has any positive effect on firm performance. Indeed, for family-owned firms we find that the effect is negative. In general, sub-indices measuring effective compensation, disclosure and shareholder rights practices enhance performance and this is true for most ownership types. We also find no evidence that governance practices are endogenous.

    Notes: We suggest that the equivocal empirical results of board leadership structure on firm performance have both methodological and conceptual roots. We stress that whether board leadership structure enhances or lowers performance depends on its fit with a firm's internal and external conditions, a point that has not been comprehensively addressed by the extant literature. To guide future research in this field, we develop five testable propositions and offer some suggestions on how these propositions may be empirically tested.

    Notes: This paper examines the effects of board of directors’ network characteristics on firm performance using a sample of 199 large, publicly traded Korean companies from 1990 through 1999. Two board network characteristics are discussed, namely: board network density and board external social capital. Board network density is defined as the extensiveness or the cohesiveness of contact among the members of board of directors, and board external social capital refers to the degree to which board members have outside contacts in the external environment. The test results suggest that a moderate level of board network density enhances firm value, while too cohesive a board network destroys it. It is also found that board members’ elite school networks were positively associated with firm performance.

    Notes: Under what conditions do stakeholders consent to a regime of corporate governance? We propose that consent by the governed in corporate governance cannot be satisfactorily explained without reference to the collective value of procedural fairness that underlies markets. Drawing on the social psychology of justice and the political economy of social choice, we highlight the critical role played by democratic procedures in achieving consent by the governed in modern society. This line of reasoning leads us to suggest that the evolution of corporate governance, too, can be understood in terms of Tocqueville's well-known hypothesis that democracy eventually prevails in all spheres of organised activity. Examining the historical record of institutional reform in France, Germany, the United Kingdom and the United  States,  we  find  that  corporate  governance  has  indeed  evolved  to  make  increasing  use of democratic procedures. Viewed over the long-term of two centuries of capitalist development, corporate governance is seen to have successively incorporated enfranchisement, separation of powers and representation. In conclusion, we consider the implications of basing the study of corporate governance on the question of stakeholder consent and the practice of corporate governance on the procedures of democracy.

    Notes: Recent debates on the corporate governance role of institutional investors have centred around whether they monitor their portfolio firms (exercise voice) or vote with their feet (exit). We examine these competing views in the context of how institutions’ voice vs exit role, proxied by institutional ownership levels, is associated with their portfolio firms’ earnings management in multiple settings. We extend Koh (2003, The British Accounting Review, 35, 105–128) by examining the effect of both short-term and long-term oriented institutional ownership on the extent of earnings management by portfolios firms with different incentives for earnings management. Specifically, we expect that the non-linear relation between institutional ownership and earnings management found in Koh (2003) is more likely to be present for portfolio firms with stronger incentives to meet/beat earnings thresholds. Our results suggest that transient and long-term oriented institutions co-exist and have differential effects on portfolio firms’ earnings management. Transient institutions are associated with upward accruals management, while long-term oriented institutions constrain such upward accruals management for portfolio firms that have strong incentives to do so (specifically, firms with non-discretionary earnings below prior year earnings). This suggests long-term oriented institutions can act as a corporate governance mechanism to mitigate aggressive earnings management. Overall, we find that the association between institutional ownership and earnings management is not systematic across all firms and is context dependent, suggesting complex associations between institutional ownership and earnings management strategies exist.

    Notes: Agency theorists have put forth a number of internal control mechanisms that can reduce agency problems. These different mechanisms are substitutive and thus it is thought that both the board of directors and large external shareholders can influence CEO compensation. Stewardship theory challenges the presumption of self-interest of agency theory, holding that managers view themselves as stewards of their organisation. The first objective of this paper is to study the influence of the control of the board of directors and large external shareholders on CEO compensation. The second objective is to utilise both stewardship and agency theory to analyse the relationship between control mechanisms and compensation, and to see which theory is more applicable. This paper uses the LISREL model to study the influence that the control of the board of directors and external large shareholders has upon CEO compensation, with data drawn from samples of listed manufacturing companies between the years 1997 and 1999 in Taiwan. The following conclusions are reached: (1) the paper supports the viewpoint of stewardship theory whereby the CEO acts as a steward of his/her company when he/she also holds the position of chairman of the company. (2) The findings show that CEO compensation will be high when the board's control is relatively ineffective. (3) The shareholdings of the board of directors can reinforce the degree of control from the board.

    Notes: There is a need for regional studies of women on corporate boards to capture experiences of smaller companies and to understand the nature of local resources for expanding the pool of women candidates for board seats. New findings from a statewide study of women on corporate boards are reported. The paper examines the status of women on corporate boards compared to other regions in the United States and around the world. Change efforts of governments and professional organisations for helping women overcome barriers to the boardroom are described to demonstrate the need for local knowledge in determining an effective change approach. Results from this study indicate that the local pool of women in academia and consulting has provided alternative routes to the boardroom. This knowledge can be used to direct change efforts for promoting women on boards. Practical implications are discussed for women seeking board seats and for firms seeking qualified women director candidates.

    Notes: Empirical literature on corporate governance often assumes independence among different control mechanisms. However, different studies in the Anglo-Saxon context find that control mechanisms are interrelated. The Spanish corporate governance system, unlike the Anglo-Saxon one, is characterised by the dominance of internal controls, mainly the stock ownership concentration and the board of directors. In this internal control context, we specifically analyse the possible substitution of the supervisory potential of the board outsiders by the incentive effects derived from managerial stock ownership and the supervisory role of large shareholders. Our main results show a negative relationship between the proportion of outside directors and managerial and large blockholders’ ownership stake. These findings support the substitution among internal controls and suggest that Spanish firms form an efficient conglomerate of managerial controls, in which deficiencies in a single mechanism can be compensated by the action of an alternative one.

    Notes: In Australia, as in many Western industrialised countries, women accessing corporate board positions are still the exception to the rule. This paper reports research exploring men's and women's views on the factors crucial in attaining a board position. While both groups identified the importance of a strong track record, a good understanding of business principles and business contacts in gaining board positions, we found that women also highlighted the importance of high visibility and family contacts to account for their nomination to boards. It seems that women's competence has to be widely acknowledged in the public domain or through family connections before boards, or their nominating committees, will be prepared to “risk” having a woman on the board.

    Notes: Corporate governance systems develop as a result of cultural underpinnings, legal structures and different forms of financing business. This paper describes these factors in the US and UK, two examples of strong shareholder ownership patterns of financing, and Germany, a country with a tradition of strong creditor financing. Recommendations are made for best practices in governance. Although enhanced governance mechanisms is a sound goal to pursue, the results may be meaningless unless internal controls are strengthened and top management and the board of directors establish an ethical tone at the top.

    Notes: The challenge for boards is to prevent crises in the organisations they govern. Performance evaluation is a key means by which boards can recognise and correct corporate governance problems and add real value to their organisations. Our paper provides a practical introduction to board and director evaluations. We discuss the reasons for governance failures and how board evaluations can help prevent them from occurring. We then review the performance pressures facing boards and the benefits of board evaluations in meeting these pressures. Finally, we introduce our framework for a successful board and/or individual director evaluation, whatever the company type. In this framework, we suggest there are seven key questions to consider when planning a board evaluation and discuss each of these seven decision areas.

    Notes: The catastrophe caused by the failure of Enron could not compare with the damage this company would have caused if it had succeeded. The relentless emphasis on the importance of shareholder value in recent times has created the conditions for the disconnection of corporations such as Enron from their essential moral underpinnings, encouraging them to concentrate exclusively on financial performance, and to neglect not just the wider stakeholder interests of customers and employees, but the essential interests of the economies and communities in which they operate. The problem with established economic theories of corporate governance is that they misconceive the irreducible core of corporate governance, at the same time as underestimating the complexity of the phenomenon.

    Notes: Based on British legislation, the duties of directors are stated in the New Zealand Companies Act 1993. However, “good” governance is not defined within the Act. Considering the relative importance attached by boards to a variety of governance tasks, this paper evaluates directors’ perceptions of the current contribution of fellow board members to different aspects of governance practice. This evaluation is discussed in relation to the influence of board tasks and functions on actions that may be regarded as being in the interests of the company as defined by the Act. The evaluation illustrates the strategic orientation of the board, highlighting the extent to which individual directors and the board as a whole can actually influence key outcomes and, thereby, their governance contribution. The paper reports responses to findings based on a study involving 3000 directors and presents suggestions for enhancing board processes as well as possible changes in expectations that could be encapsulated in legislation.

    Notes: The Canadian Securities Administrators’ National Policy 58-201 Corporate Governance Guidelines (the “Policy”),1 released 15 April 2005, on which the author provided detailed advice, reads that:〈list style="custom"〉• “[t]he board should develop clear position descriptions for the chair and the chair of each board committee” (section 3.5);• the board should engage in an explicit two-step “competencies and skills” recruitment of individual directors (sections 3.12 and 3.14);2 and• individual directors should be regularly assessed and that these assessments should consider “the applicable position description(s), as well as the competencies and skills each individual director is expected to bring to the board” (section 3.18).The Canadian Securities Administrators, subject to receiving the required approvals, intend for the Policy to come into force in Canadian jurisdictions on 30 June 2005.This article canvasses some of the aspects in assessing board leadership.

    Notes: This study, based on a comparison of the Combined Code Guidelines for non-executive directors between listed and unlisted boards, suggests that on unlisted boards non-executive directors have a greater degree of involvement in strategic development, financial monitoring, shareholder communication and overall board contribution than on listed boards, but a lesser degree of involvement in the monitoring of management, the setting of executive remuneration, the appointment and removal of executives, and succession planning. The importance of risk analysis and induction is considered high across both sectors, although board development and independence is considered less important on unlisted boards.

    Notes: Among the many roles boards of directors perform, the monitoring role of the board has received the most attention recently, resulting in higher demands on boards and directors to be vigilant monitors. By presenting a framework to tailor the monitoring role of the board to the specific situation and needs of the company, this paper tries to overcome the negative effects of an excessive focus on control. In so far as boards are, to a certain extent, free to define their own delegation policy, this framework highlights two essential decisions of the board, namely the decision which responsibilities and authorities are delegated to management and the decision whether to delegate them to a single-headed or joint management. Some preliminary empirical findings supporting the central argument are presented, together with some suggestions for further research.

    Notes: After the emergence of the Cadbury Report in 1992, several countries in the EU, including Denmark, issued their own guidelines of corporate governance. However, whether such recommendations benefit shareholders is a controversial question. This article presents an empirical analysis of financial performance and the composition of semi-two-tier boards using a unique sample of Danish listed firms. It is shown that board size, proportion of insiders and positions held by board members in other firms do not significantly impact performance. Only the average age of the board has a significantly negative impact on performance. Thus, it is argued that board structure only plays crucial role when a firm is in financial trouble or faces a major threat – not under normal circumstances.

    Notes: Corporate governance frameworks can be perceived as institutional attempts to create a structured dialogue between companies and their shareholders and stakeholders with the purpose of paving the way for understanding the company's strategic and operational goals, including critical success factors for achieving those goals. This article focuses on the disclosure on corporate governance in Danish companies (SMEs). It also provides evidence from the literature as well as analyses of company annual reports. Furthermore, the findings open the way for a discussion on further research on corporate governance and disclosure on strategic management and transparency.

    Notes: The aim of this paper is to distinguish between different roles of boards of directors in companies and to fit the theoretical debate into a framework for better understanding. A simple framework, constructed from the literature, is used to distinguish between the archetypes of roles from a two-dimensional perspective. The paper includes a preliminary qualitative study of Icelandic companies with the aim of testing the framework and exploring the roles of boards in Iceland. The study shows that boards have various roles or patterns of roles and that the roles can change with change of circumstances.

    Notes: This study examines the behavioural biases of Japanese institutional investors and discusses implications for their role in corporate governance, based on the findings of a questionnaire survey of fund managers carried out in 2003. Statistical analysis of the survey results reveals a short-term bias in fund managers’ investment time horizons, herding and self-marketing to improve the appearance of portfolio performance under the pressure either of customers or of institutional restraints. We conclude that institutional investors’ behaviour contradicts their role as shareholders.

    Notes: The paper discusses to what extent Parmalat's failure can be considered a particularly Italian case. The main characteristics of Parmalat's corporate governance structure are compared and contrasted with those prevailing among Italian listed companies as well as with the highest corporate governance standards in Italy. Empirical evidence seems to confirm the lack of a monitoring structure in making corporate insiders accountable in the presence of a corporate governance system characterised by a controlling shareholder. The role of the ownership and control structure (with special regard to the controlling shareholder's role) and of the board of statutory auditors have Italian traits and might suggest that the Parmalat case is a particularly Italian scandal. However, Italian corporate governance standards were not completely at fault in the Parmalat case. Parmalat's corporate governance structure failed to comply with some of the key existing Italian corporate governance standards of best practice, such as the presence of independent directors and the composition of the internal control committee. Besides, the role of the external auditor as well as the internal control committee as non-effective monitors seem to put Parmalat into the global argument case, not very different, mutatis mutandis, from other corporate scandals.

    Notes: In recent years there has been some debate and uncertainty about the legality of private briefings of some market participants with the management of listed companies in the UK. The Myners (2001) and Higgs (2003) Reports have suggested an increasingly active role for institutional shareholders. However, the message from the Financial Services Authority in its role as the United Kingdom Listing Authority has been that private briefings may be unlawful. This article explores the meaning and scope of the legal rules on insider dealing and market abuse under the Financial Services and Markets Act 2000, the Criminal Justice Act 1993 and those parts of the Listing Rules that govern such briefings. The extent to which such rules apply to various types of meeting between corporate managers and other market participants, such as institutional investors, and the information provided in those meetings, will also be examined. The paper concludes that the mismatch between the apparent legal position and the policy objective of the Government of increasing institutional shareholders’ activism requires a resolution.

    Notes: This paper examines how different control mechanisms relate to one another in the Spanish corporate governance system. We propose a new empirical approach that consists of analysing control mechanisms according to the non-linearity of the value-ownership relation, and emphasising entrenchment and expropriation phenomena. Our evidence contributes to understanding the role played by several control mechanisms in the Spanish corporate governance system, which largely differs from the US one. Our results show that control mechanisms (especially insider ownership, debt and dividends) are used in a complementary way by Spanish firms. Additionally, this complementarity is only observed when the interests of managers and owners converge, but not when there are controlling owners whose interests need not coincide with those of minority shareholders. Therefore, entrenchment and expropriation effects do influence the relationship among control mechanisms.

    Notes: Post 1992 Cadbury Committee report developments in UK corporate governance provisions are reviewed. The role of institutional investors, and the financial sector as a whole, in corporate governance is considered. Practices in “Continental Europe”, the UK and the US are contrasted, along with the roles of banks, strategic investors (“insiders”), institutional investors (“outsiders”) and capital markets. To be effective, capital markets must be efficient and competitive and auditing must be reliable. Current EU and US reform proposals are compared and prospects for convergence in corporate governance procedures assessed.

    Notes: In the UK there has been a recent debate over the role of the independent non-executive director, with that debate resulting in changes to a revised Code applicable to companies reporting after 1 November, 2003. This article reflects on an aspect of the proposed changes that was ignored, namely changes to the legal duties and liabilities of non-executive directors. This appears to have been a missed opportunity in seeking to enhance the effectiveness of independent non-executives and their contributions to enhancing corporate governance. This paper considers enhancing the governance role of non-executive directors by introducing “gatekeeper liability”.
