The board's role in risk disclosure: an exploratory study of Italian listed state-owned enterprises

The determinants of risk disclosure in the annual reports of listed state-owned enterprises (SOEs) have yet to be fully explored. This paper examines the potential impact of the composition of the boards of directors and other company-specific features on risk disclosure levels. The presence of women on a board made a significant difference to risk disclosure, as did the age of board members. Board directors having an accounting or finance/business qualification affected risk disclosure negatively; company size and an internet visibility were positively related to risk disclosure. Although an Italian study, the lessons here will have application to academia and to practitioners, policy-makers and standard-setters worldwide.     

Managing severe airspace flow programs: The Airlines’ side of the problem

This paper presents a heuristic-based approach for minimizing airlines’ schedule disruptions and operation costs associated with severe airspace flow programs. It considers primary decisions made by flight dispatchers such as flight slot substitution and rerouting outside the boundaries of the flow-constrained area. A two-stage heuristic is developed. In the first, a linear approximation of the problem is used to screen inefficient routing and slot substitution alternatives. The second stage examines possible solution improvements through trading flight assignments for every pair of conflicting routes. A genetic algorithm is developed and used to benchmark the performance of the two-stage heuristic. In the algorithm, flight route and slot allocation schemes are modeled as chromosomes. The fitness of these chromosomes measures the magnitude of schedule disruption and overall operating cost. A set of experiments that compare the performance of the two heuristics considering airspace flow programs with different levels of severity is presented.

RPMInter-work: a multi-agent approach for planning the task-role assignments in inter-organisational workflow

ABSTRACT

Workflow management is a core component of modern Enterprise Information Systems (EISs) infrastructure that automates the execution of critical business processes. One of the particular interests of the security community is how to ensure the completion of the workflow execution in the presence of authorisation constraints. These constraints present some restrictions on the users or the roles that are authorised to execute the workflow tasks. The goal is to enforce the legal assignments of access privileges to the executors of the workflow tasks. Despite the variety of approaches proposed in this context, an approach dedicated to the inter-organisational workflows is still missing. In this paper, we take a step towards this goal by proposing a multi-agent-based model, named RPMInter-Work (task-Role assignment Planning Model for Inter-organisational Workflow). Our approach aims to perform the planning of the task-role assignments in inter-organisational workflow in presence of authorisation constraints that are related to task-role assignments. In our research work, this planning problem is formulated as a DisCSP (Distributed Constraint Satisfaction Problem). Our proposed contribution is based on the requirements of inter-organisational workflows, in particular, the autonomy of the participating organisations and the respect of their privacy. A prototype of RPMInter-Work is implemented using JADE (Java Agent DEvelopment) platform and some evaluation results of this prototype are exposed in this paper.

Stock exchange demutualization,self-listing and performance: The case of the Australian Stock Exchange

This paper examines the effects of the recent spate of financial exchange mutual-to-stock conversion phenomenon on the performance of listed exchanges and the quality of the stock market using the Australian Stock Exchange (ASX) as a case study. We find that the ASX stock significantly outperformed the stock index and the control group on a market-adjusted return basis. The stock market performance is driven by strong operating performance. The profitability ratios of the ASX have significantly improved in the five years following the demutualization and self-listing. The performance improvements remain significant even after controlling for growth in the Australian economy. From a market quality perspective, we document evidence of increased trading activity by foreign investors after ASX’s demutualization and self-listing. Interestingly, we also find that bid-ask spreads of the stock market have narrowed in the post-conversion period. In particular, small-cap firms have become more liquid. The results show that stock exchange conversion from mutual to publicly traded exchange is not only value enhancing for the exchange and its shareholders, but it is also beneficial for the stock market as a whole.     

A Distance-Based Collective Preorder Integrating the Relative Importance of the Group's Members

In this paper, we propose an aggregation procedure, which includes two steps. In the first one, the group's members elaborate individually a preorder (total or partial) on the alternatives set. These preorders can be obtained, for example, by applying a multicriterion aggregation procedure such as ELECTRE III, PROMETHEE I or II. In the second step, these individual preorders (total or partial) are aggregated into a collective preorder (total or partial). For this purpose, we first built a distance measure between pairs of binary relations in order to quantify the divergence between two preorders. Then we determine, for each pair of alternatives, the relative importance coefficients of the group's members by using a method based on subjective and objective components. These coefficients and the distance measure are finally exploited by an iterative algorithm in order to elaborate a collective preorder synthesizing the individual preorders.     

Resource-based theory in marketing

The use of resource-based theory (RBT) in marketing research has increased by more than 500% in the past decade, which suggests its importance as a framework for explaining and predicting competitive advantages and performance outcomes. This article provides a comprehensive review of RBT, including a contemporary definitional foundation for relevant terms and assumptions and a synthesis of empirical findings from marketing literature. This multidimensional analysis of RBT also evaluates extant marketing research according to four perspectives: the marketing domains that use RBT, the characteristics and uses of market-based resources that differentiate it from other research contexts, the extension of RBT to the “marketing exchange” as a unit of analysis, and the connection of RBT to related theories. This analysis also reveals some common pitfalls associated with prior research, offers tentative guidelines on how to improve the use of RBT in marketing, and suggests research directions to advance the theorization and empirical testing of RBT in the future.     

Understanding the Determinants of RiskMetrics/ISS Ratings of the Quality of UK Companies' Corporate Governance Practice

We examine the determinants of RiskMetrics/ISS Ratings of the quality of UK companies' corporate governance practice and investigate whether corporate governance mechanisms and firm specific characteristics affect these ratings. We also investigate the association between firms' financial distress and these ratings. Using data for nonfinancial Financial Times Stock Exchange (FTSE) 250 firms over the 2003 to 2009 period, we find that board independence, managerial ownership, institutional ownership, firm size, and profitability are associated with firms' corporate governance ratings. In addition, we find that more independent directors on the board, more institutional ownership, and larger size lead to a high level of board‐related ratings. Finally, we find no association between corporate governance ratings and financial distress. Copyright © 2012 ASAC. Published by John Wiley & Sons, Ltd.
