Abstract
The incorrect behaviour of Graphical User Interfaces (GUIs) can compromise the effective use of the overall software application. One way to discover defects and increase the quality of GUIs is through testing. Test cases can be created manually or produced automatically from a model of the GUI. The size and complexity of GUIs makes it unpractical to do extensive manual testing. However, creating a model of the GUI in order to generate automatically test cases is also a laborious task. This paper presents a reverse engineering approach for diminishing the effort required for constructing the model of an existing GUI. The GUI is exercised by a combination of manual and automatic exploration, and information about its structure and some of its behaviour is automatically extracted, resulting in an incomplete GUI model. This model is subsequently completed manually, validated and used as input for automatic test generation and execution.

Abstract
In today's changing environments, organizational design must take into account; the fact that business processes are incomplete by nature and that they should be managed in such a way that they do not restrain human intervention. In this paper we propose the embedding of social software features, such as collaboration and wiki-like features, in the modeling and execution tools of business processes. These features will foster people empowerment in the bottom-up design and execution of business processes. We conclude this paper by identifying some research issues about the implementation of the tool and its methodological impact on Business Process Management.

Abstract
Meta-architectures, also known as reective architectures, are a specific type of software architectures that are able to inspect their own structure and behavior, and dynamically adapt at runtime, thus responding to new user requirements or changes in their environment. In object-oriented programming, these architectures rely on a small set of core concepts that provide them the means to describe themselves, thus becoming"closed". These three core patterns can be found in almost every object-oriented meta-architecture: Everything is a Thing, Closing the Roof, and Bootstrapping. By delving into the inherent problems they try to solve, and the forces that shape those problems, a developer will improve his ability to adequately make architectural and design choices to build and evolve systems with high-adaptability needs.

Abstract
Documentation is an important part of the captured knowledge of a software project, providing a flexible and effective way of recording informal contents. However, maintaining documentation's consistency requires a considerable effort. Existing solutions encompass different tools and approaches that support the process of creating, evolving and using documents and other artifacts derived from the software development process. Based on existing literature and expertise, we have identified the key problems and solutions for documentation consistency. In concrete, four distinct patterns and their relations were identified, which are here described - Information Proximity, Co-Evolution, Domain-Structured Information and Integrated Environment.

Abstract
This work addresses software quality issues introduced by Aspect-Oriented Programming (AOP). AOP aims at enhancing modularity and thus solving the problem of crosscutting concerns by capturing them into new units of modularity called aspects. With the increasing usage and acceptance of AOP, the task of assuring aspect-oriented systems' correctness has become a challenge, mainly due to its nature. Although several testing techniques have been applied and improved for object-oriented programs through the years, there is still the problem of selecting and verifying which ones can be effectively applied to AOP. This paper presents a perspective on how AOP can improve quality (when applied correctly), identifies a set of key testing issues that arise with AOP and presents weaknesses and strengths of the existing solutions to improve quality in AOP.
