This paper proposes the use of metrics in design space exploration that highlight where in the structure of the model and at what point in the behaviour, prevention is needed against transient faults. Previous approaches to tackle transient faults focused on recovery after detection. Almost no research has been directed towards preventive measures. But in real-time systems, hard deadlines are p...

Although a "system approach" to accidents in sociotechnical systems has been frequently advocated, formal system theoretic concepts remain absent in the literature on accident analysis and system safety. To address this gap, we introduce the notions of coordinability and consistency from the hierarchical and multilevel systems theory literature. We then investigate the applicability and the imp...

BACKGROUND Since 2009, Fundación Mundo Sano has implemented an Aedes aegypti Surveillance and Control Program in Tartagal city (Salta Province, Argentina). The purpose of this study was to analyze temporal dynamics of Ae. aegypti breeding sites spatial distribution, during five years of samplings, and the effect of control actions over vector population dynamics. METHODOLOGY/PRINCIPAL FINDING...

Corporations have repeated reported incidents of misuse of material non-public information for illegal insider trading. Though information technologies are being inappropriately used to assist in these activities, creatively using emerging technologies and business process can also aid in preventing and detecting insider trading. This paper first discusses the issues relating to insider trading...

BACKGROUND Trials of complex interventions are associated with high costs and burdens in terms of paperwork, management, data collection, validation, and intervention fidelity assessment occurring across multiple sites. Traditional data collection methods rely on paper-based forms, where processing can be time-consuming and error rates high. Electronic source data collection can potentially add...

Fetal alcohol spectrum disorders (FASD) is caused by maternal drinking during pregnancy. Pre-natal drinking has a range of deleterious effects including physical, mental and behavioural consequences for the affected child. Although FASD is completely preventable, it is irreversible with consequences that last into adulthood. The range of effects of FASD forms a spectrum with fully developed FAS...

Assessment tools based on static and linear concepts like traditional cost-benefit analysis can not reasonably be applied for long-term assessments of complex systems. One major reason is that secondary effects of policies caused by endogenous dynamics of the system are not considered. So, for environmental impacts the Strategic Environmental Assessment (SEA) is developed that already includes ...

Attacks on computer systems have received a great deal of press attention; however, most of the focus has been on how an attacker can disrupt an organization’s operations. Although attack prevention is clearly preferred, preventive measures do fail, and some attacks inevitably succeed in compromising some or all of particular systems. We adopt a fault tolerance approach that addresses all phase...
