Service-oriented architecture (SOA) is a popular design paradigm for distributed systems today but the high adaptivity and complexity of SOA implementations may also introduce additional sources of faults. We first describe typical steps in SOA to understand possible faults. Then, we provide a corresponding fault taxonomy according to the process of service invocation. Finally, we present possible benefits of our taxonomy for dependability enhancement in SOA-based systems.

Previous research by the Modena Group on Stalking (MGS) regarding awareness and recognition of stalking by police officers and general practitioners using case scenarios showed significant differences across three countries. It was also hypothesized that victims used different pathways when seeking help. To explore the experience of requesting help by victims of stalking in different European countries a detailed survey was completed by 391 victims of stalking in Belgium (n = 145), Italy (n = 126) and Slovenia (n = 120). The research confirmed the significant intensity and duration of stalking and psychological distress for victims. Victims used several pathways to survive stalking. Some victims reported that informal interventions they or family/friends implemented were effective, but the majority had to have recourse to helping agencies. Significant differences in help seeking behaviour were found between the three countries. In Belgium victims contacted the police, as well as other helping agencies, more often and more precociously than in Italy and Slovenia. Restriction orders against the stalker were considered the most effective intervention. Police were regarded as the least supportive agency, taking victims less seriously, and not being particularly effective at stopping the stalkers. Police were ranked after family/friends, lawyers and colleagues, with regards effectiveness, except in Belgium, where Police’s effectiveness was ranked second after lawyers. Stalking often requires the mobilization of multiple helping agencies by victims and it is important that victims are aware of what help is available to them and that agencies become more sensitive to their needs.

The presence of MEs has proven to strengthen the Indonesian economic stability. They are important for several reasons: their contributions to the national production, the total units of enterprises, and the creation of employment. Despite the fact that MEs are very potential for building a stable economic growth, developing MEs is a challenging issue. The most critical problem in today’s Indonesian MEs lies on Human Capital related issues. The study aims to explore the current Human Capital Management (HCM) initiatives and how it affect the sustainability of the organization. More specific, the study aims to describe the HCM policies, programs, and practices being employed by medium-sized manufacturing enterprises, and what factors act as enablers that motivate human capital to undertake the current HCM policies, programs, and practices. By using case study approach, preliminary prepositions are developed.

System testing is concerned with testing an entire system based on its specifications. In the context of object-oriented, UML development, this means that system test requirements are derived from UML analysis artifacts such as use cases, their corresponding sequence and collaboration diagrams, class diagrams, and possibly the use of the Object Constraint Language across all these artifacts. Our goal is to support the derivation of test requirements, which will be transformed into test cases, test oracles, and test drivers once we have detailed design information. Another important issue we address is the one of testability. Testability requirements (or rules) need to be imposed on UML artifacts so as to be able to support system testing efficiently. Those testability requirements result from a trade-off between analysis and design overhead and improved testability. The potential for automation is also an overriding concern all across our work as the ultimate goal is to fully support testing activities with high-capability tools.

Distributed Real-time Embedded (DRE) systems are increasingly used in critical domains such as avionics, vehicle and industrial control as well as in medical systems. They must be designed carefully and have to provide safety properties because a failure could mean loss of life. For these reasons, it is recommended to automatically generate a significant part of the code from the models describing the critical aspects. In our approach, we automatically generate two kinds of code from architectural models. The first one plugs the user functional code in the middleware, the second one provides a significant part of the middleware functions. Both rely on a hand coded written middleware that provides the minimal facilities to plug the generated code and to resolve portability issues. In this paper, we present our code generator and the middleware designed to generate High Integrity (HI) systems. We demonstrate via several use-cases how we succeeded in meeting the requirements of DRE sys...

Abstract. Free/Libre and Open Source Software (FLOSS) is a process of software development, a method of licensing and a philosophy. Although FLOSS plays a significant role in several market areas, the impact in the health care arena is still limited. FLOSS is promoted as one of the most effective means for overcoming fragmentation in the health care sector and providing a basis for more efficient, timely and cost effective health care provision. The 2008 European Federation for Medical Informatics (EFMI) Special Topic Conference (STC) explored a range of current and future issues related to FLOSS in healthcare (FLOSS-HC). In particular, there was a focus on health records, ubiquitous computing, knowledge sharing, and current and future applications. Discussions resulted in a list of main barriers and challenges for use of FLOSS-HC. Based on the outputs of this event, the 2004 Open Steps events and subsequent workshops at OSEHC2009 and Med-e-Tel 2009, a four-step strategy has been pr...

Lack of knowledge and skills among small business managers has been well recognised, but how to effectively support small business managers in their knowledge acquisition and decision making with emerging information and communication technologies is still a challenge. This paper describes an application attempt to develop an intelligent web-based training system for SMEs to aid their learning and decision-making regarding the use of the Internet as a new marketing medium. Based on the training needs analysis carried out by a EU-funded research project TRIMAR, a case-based reasoning (CBR) approach is adopted as an effective tool to help small business managers to learn and to make better decisions. Over seventy small business Internet marketing cases were collected and processed. They form a case base for CBR in the system. The initial feedback from users proves using case base reasoning approach is effective, but the quality and the comprehensiveness of case base are key factors fo...

Sandplay therapy has been utilized with various populations, including those with posttraumatic stress disorder (e.g., Coalson, 1995), children with traumatic brain injury (e.g., Plotts, Lasser, & Prater, 2008), and individuals with substance abuse problems (e.g., Marcello, 2008). However, there are scant references to the employment of sandplay therapy with individuals with dementia. Using case studies from the author’s own work, the article provides concrete illustrations of how sandplay therapy may be a significant mode of therapy to consider in working with dementia. This article also explores how sandplay facilitates the individuation process, provides a venue for nonverbal therapy, and promotes the exploration and deepening of an individual’s connection with the unconscious mind. Implications for research are also discussed.

Offshore and outsourced distributed software development models and processes are facing challenges, previously unknown, with respect to computing capacity, bandwidth, storage, security, complexity, reliability, and business uncertainty. Clouds promise to address these challenges by adopting recent advances in virtualization, parallel and distributed systems, utility computing, and software services. In this paper, we envision a cloud-based platform that addresses some of these core problems. We outline a generic cloud architecture, its design and our first implementation results for three cloud forms - a compute cloud, a storage cloud and a cloud-based software service- in the context of global distributed software development (GSD). Our ”compute cloud” provides computational services such as continuous code integration and a compile server farm, ”storage cloud” offers storage (block or file-based) services with an on-line virtual storage service, whereas the on-line virtual labs represent a useful cloud service. We note some of the use cases for clouds in GSD, the lessons learned with our prototypes and identify challenges that must be conquered before realizing the full business benefits. We believe that in the future, software practitioners will focus more on these cloud computing platforms and see clouds as a means to supporting a ecosystem of clients, developers and other key stakeholders.
