Increasing size and complexity of software projects have triggered the use of domain-specific languages (DSL). Multiple DSLs, some with cross-cutting concerns, are used to describe software systems. In context of long-living software systems, requirements change over time causing an evolution of domains and subsequently the corresponding DSLs. Transformations are used to generate models and cod...

Role engineering for role-based access control (RBAC) is a process to define roles, permissions, constraints, and role hierarchies. The scenario-driven role engineering process provides a systematic way to elicit the RBAC components. However, the traceability between those components has not been well analyzed. As a result, it is both time-consuming and error-prone to modify the RBAC components...

Software product line engineering has emerged as an approach to developing software which targets a given domain. However, the processes involved in developing a software product line can be time consuming and error prone without adequate lifecycle tool support. In this paper we describe our approach, NAPLES, which uses natural language processing and aspectoriented techniques to facilitate req...

Aspect languages provide different mechanisms to control when an aspect should apply based on properties of the execution context. They however fail to explicitly identify and cleanly capture a property as basic as that of reentrancy. As a result, aspect developers have to resort to low-level and complex pointcut descriptions that are error prone and hamper the understandability of aspect defin...

Introduction: Cognitive linguists believe that metaphor is a cognitive phenomenon, and that what appears in language is just the aspect of cognitive phenomenon Metaphor is one of the basic interdisciplinary concepts that has been paid more attention to its fundamental role in various aspects of psychology, medicine, including cancer in recent years. Methods:. From the point of view of cognitiv...

The capacity to manage financial affairs is a fundamental aspect of individual autonomy in society and represents a cognitively complex set of knowledge and skills that are sadly particularly vulnerable to cognitive aging and

1 Problem Setting Financial markets (FiMa) are often designated as " complex systems " (Johnson et al. 2003, p. 3; Farmer and Foley 2009, p. 685). From the perspective of system theory, this view implies two aspects: Firstly, FiMa can be interpreted as systems having structure and behavior. Secondly, such systems have high structural and behavior-al complexity (e.g. Klir 1969, pp. 50). Investor...
