This paper presents a literature survey of action research (AR) studies published in nine major Software engineering (SE) journals and three conference proceedings in the period 1993 to June 2009. A strict selection based on distinguishing SE from Information systems research has identified 16 papers. Although they represent a very small fraction of the studies being conducted in SE, such papers concern with different SE contexts allowing to get information about the increasing tendency in the AR use in software engineering. However, as shown by the initial results, SE researchers should invest more on rigor when defining, applying and reporting AR studies in SE. © 2009 IEEE.

We have proposed a checklist-based usability inspection technique (WDP - Web Design Perspectives-Based Usability Evaluation) specific for Web applications' usability evaluation and we are following an experimentation-based methodology to support its development and improvement. This paper describes an observational study conducted, aimed at eliciting how inspectors apply the WDP technique. We discuss the quantitative and qualitative results of the result and their impact on improving the WDP technique. We analyzed the qualitative data using the procedures from the Grounded Theory (GT) method. © 2009 IEEE.

Peer-to-peer (P2P) offers good solutions for many applications such as large data sharing and collaboration. Thus, it appears as a powerful paradigm to develop scalable distributed applications, as reflected by the increasing number of emerging projects based on this technology. However, building trustworthy P2P collaborative tool is difficult because they must be deployed on a large number of autonomous nodes, which may be part of the virtual community and to make the collaboration effectively happen among the nodes. Within this scenario, this article presents an autonomic recommendation mechanism of knowledge chains, which is based on the apprentice profile and his current knowledge to recommend the best learning strategy after the analysis of the learning community in this peer-to-peer environment.

In a decision-making process, a systematic method to manage and measure negotiation aspects provides crucial information to negotiators and has emerged as a key factor to determine agreements' success or failure. Accordingly, this work aims at presenting a negotiation support system which provides functionalities to create negotiation models through settlements' historical information. These models are interpreted as Fuzzy Cognitive Maps (FCM) and the software tests as the convergence of each model. Thus, the system intends to facilitate decision-markers to predict future negotiations behavior and, consequently, improve the chances of an agreement. Besides, this work examines a case study through the lenses of FCM to illustrate real negotiations outcomes and expected value quantifications. The proposal is to compare a model map developed from old negotiations with the results obtained through FCM simulations. As a result, from the use of these mechanisms, negotiators could better visualize alternative ways to improve the chances of successful agreements.

The technical literature regarding Model-based Testing (MBT) has several techniques with different characteristics and goals available to be applied in software projects. Besides the lack of information regarding these techniques, they could be applied together in a software project aiming at improving the testing coverage. However, this decision needs to be carefully analyzed to avoid loss of resources in a software project. Based on this scenario, this paper proposes an approach with the purpose of supporting the unique or combined selection of MBT techniques for a given software project considering two aspects: the adequacy level between MBT techniques and the software project characteristics and impact of more than one MBT technique in some testing process variables. At the end, preliminary results of an experimental evaluation are presented.

A massively parallel hardware architecture for ray-tracing

Real time performance of non-interactive rendering of three-dimensional scenes is usually unachievable. Ray tracing is one of the methods used for rendering such scenes. The performance achieved by a sequential software-based implementation of ray tracing is far from satisfactory. In contrast, many parallel implementations of ray tracing have been enabling real time performance, as the underlying algorithm can be massively parallelised. Thus, it is expected that a custom parallel design in hardware is likely to achieve the acceptable performance standards. In this paper, we propose a hardware architecture, which we call GridRT, capable of dealing with the main desirable features of ray tracing, such as shadows and reflections effects, imposing low requirements in terms of silicon area while achieving acceptable performance in terms of rendering time. This architecture achieves is efficient yet compact as it explores the massive parallelism offered by the intrinsic structure of the algorithm. The design exploits the usage the spatial data structure of regular grids. Copyright © 2009 Inderscience Enterprises Ltd.

Knowledge has always been an advantage in any social activity that involves dispute. To possess knowledge on the domain of a negotiation can give one the edge to attain one's desired goals. In order to obtain such knowledge, an alternative can be the collaboration between allied negotiators where past experiences, acquired in negotiation, can be important and a powerful tool to future efforts. To facilitate this collaboration, this work presents an application of the 3C model for negotiation, the NK-Sys, a tool whose goal is to support the negotiator in decision-making; this tool takes Knowledge Management into account to allow cooperation between negotiators.

This work presents a spatial distribution analysis of Brazilian Atlantic Forest Bromeliad species catalogued by the Rio de Janeiro Botanical Gardens Research Institute. Our analysis aims at identifying probable endangered species and conservation areas (environmental reservations) for specific Bromeliad species. For that, we propose a solution using Data Mining techniques and the data visualization through the TerraView tool. Thus, it was possible to define where are typical species, allowing more effective field tours.

Man as a social being, as a being in social relations, is in constant motion. Such mobility affects the social networks that Man builds throughout one's existence. Networks that can consist of dozens, hundreds or even thousands of other people, with various degrees of mobility. During the formation of such networks, problems can arise, such as elements that concentrate many relationships, very isolated individuals or peripheral members of a network, people who are the only link between two distinct groups, agglomerations of people in isolated points. This can cause a series of losses to the most important element that flows through social networks: knowledge. In scientific social networks, this assertion takes even more importance, mainly on account of the mobility of researchers and the excess of knowledge circulating in it, making it more vulnerable to the movements of Man. It is with the intent of solving this problem that our work seeks to achieve success, as it analyzes the scientific social networks based on the GCC tool detects the problems related to them, and suggests recommendations of relationships to users considered harmful to the flow of knowledge in the network. We call this process of social network balancing. For the evaluation of this work we conducted a comparison with several similar proposals, and developed a working prototype, which in turn was used to make our case studies.
