Regulatory compliance management is now widely recognized as one of the main challenges still to be efficiently dealt with in information systems. In the discipline of business process management in particular, compliance is considered as an important driver of the efficiency, reliability and market value of companies. It consists of ensuring that enterprise systems behave according to some guidance provided in the form of regulations. This paper gives a definition of the research problem of regulatory compliance. We show why we expect a formal policy-based and model-driven approach to provide significant advantages in allowing enterprises to flexibly manage decision-making related to regulatory compliance. For this purpose, we contribute CoReL, a domain-specific modeling language for representing compliance requirements that has a graphical concrete syntax. Informal semantics of CoReL are introduced and its use is illustrated on an example. CoReL allows to leverage business process compliance modeling and checking, enhancing it with regard to, among other dimensions, user-friendliness, genericity, and traceability. [less ▲]

Advances in portable technologies and emergence of new applications stimulate interest in urban vehicular communications for commercial, military, and homeland defense applications. Simulation is an essential tool to study the behavior and evaluate the performance of protocols and applications in large-scale urban vehicular ad hoc networks (VANET). In this paper, we propose CORNER, a low computational cost yet accurate urban propagation model for mobile networks. CORNER estimates the presence of buildings and obstacles along the signal path using information extrapolated from urban digital maps. A reverse geocoding algorithm is used to classify the propagation situation of any two nodes that need to communicate starting from their geographical coordinates. We classify the relative position of the sender and the receiver as in line of sight (LOS) or nonline of sight (NLOS). Based on this classification, we apply different formulas to compute the path loss (PL) metric. CORNER has been validated through extensive on-the-road experiments, the results show high accuracy in predicting the network connectivity. In addition, on-the-road experiments suggest the need to refine the fading model to differentiate between LOS, and NLOS situations. Finally, we show the impact of CORNER on simulation results for widely used applications. [less ▲]

We present the corotational cut Finite Element Method (FEM) for real-time surgical simulation. The only requirement of the proposed method is a background mesh, which is not necessarily conforming to the boundaries/interfaces of the simulated object. The details of the surface, which can be directly obtained from binary images, are taken into account by a multilevel embedding algorithm which is applied to elements of the background mesh that are cut by the surface. Dirichlet boundary conditions can be implicitly imposed on the surface using Lagrange multipliers, whereas traction or Neumann boundary conditions, which is/are applied on parts of the surface, can be distributed to the background nodes using shape functions. The implementation is verified by convergences studies, of the geometry and of numerical solutions, which exhibit optimal rates. To verify the reliability of the method, it is applied to various needle insertion simulations (e.g. for biopsy or brachytherapy) into brain and liver models. The numerical results show that, while retaining the accuracy of the standard FEM, the proposed method can (1) make the discretisation independent from geometric description, (2) avoid the complexity of mesh generation for complex geometries, and (3) provide computational speed suitable for real-time simulations. Thereby, the proposed method is very suitable for patient-specific simulations as it improves the simulation accuracy by automatically, and properly, taking the simulated geometry into account, while keeping the low computational cost.

This paper analyzes the relationship between corporate governance and idiosyncratic skewness of stock returns. We test this hypothesis by analyzing the impact of external as well as internal governance provisions, and are thus able to provide an overall understanding of the relationship between governance and firm-specific return asymmetries. Our results show that better governance leads to a reduction in idiosyncratic skewness in relatively non-competitive industries. In relatively competitive industries, governance has less to no impact on firm-specific return skewness. Furthermore, an overall increase in transparency, quality and disclosure of information, proxied through the Sarbanes Oxley Act, reduces relative idiosyncratic skewness. Our findings can be regarded as detrimental for shareholders, who have a preference for positive idiosyncratic skewness. The evidence contributes to a debate, which suggests that – at the end of the day – an act like Sarbanes-Oxley, which was intended to protect shareholders from accounting errors and frauds and to improve the accuracy of corporate disclosures, comes at the expenses of shareholders. The reduction of idiosyncratic skewness through better governance collides with shareholder’s preference for idiosyncratic and positively skewed stock returns, which present a lottery like upside option of monetary gains and value creation through the right tail. This side effect of governance is also in line with the literature that highlights potential costs of corporate governance. [less ▲]

This paper analyses the rules regarding the internet-based exercise of shareholder rights for public corporations incorporated in Canada, France, Germany, the U.S. (DelGCL & RMBCA), the UK and Switzerland. The traditional doctrine associates information, communication and voting with shareholder meetings. In addition, shareholder meetings regularly prompt reviews of management's activities exercised on behalf of shareholders by accountants or the judiciary. The analysis reveals that the current regimes of shareholder meetings merely provide for voting and information in the context of a digital environment, while communication and review is usually not replicated. The lack of all functions of traditional shareholder meetings is one reason of why exclusively virtual shareholder meetings have not gained widely spread acceptance across jurisdictions. Another reason is that a well-fitting design for the web-based exercise of shareholder rights does not yet exist. Thus, the paper develops an advisable design of Virtual Shareholder Meetings that replicates all for functions of traditional shareholder meetings, while it is likely to reduce shareholder apathy at the same time. It argues that enabling more frequent opportunities for voting is the logical consequence of the developments of continuous disclosure requirements and continuous buy/hold/sell-decisions by market participants. Therefore, the virtual exercise of shareholder rights should be achieved through (1) liberalizing currently existing legislative and practical barriers, and in particular, time and place restrictions on shareholder meetings; (2) re-integrating analyst and institutional investor meetings in the process of shareholder meetings, and (3) substituting for the traditional face-to-face accountability of managers to shareholders through specific electronic means. The latter involves, specifically, the use of RSS-Feed and XBRL-technologies for gathering and evaluating information, the use of the company's website as the central communication platform for management to shareholders and shareholders to shareholders, and the election of an independent shareholder rights manager (firm) by the shareholder body with procedural, technical, and organizational authority for organizing the exercise of shareholder rights. Ideally, the blueprint presented herein achieves the harmonization of voting behavior and market reactions, thereby furthering market efficiency. [less ▲]

This article examines the effects of excess control rights of the controlling shareholder and the presence of multiple large shareholders on financial constraints, proxied by cash flow sensitivity of cash. Using a unique data set of 745 French listed firms during 1998—2013, the results show that firms have high cash flow sensitivity of cash when the controlling shareholder’s control rights exceed its cash-flow ownership. This sensitivity decreases, however, with the contestability of the controlling owner’s power. Taken together, these findings provide empirical support to the argument that firms experiencing excess control rights face considerable financial constraints that are lowered in the presence of high control contestability.
