"Behavioral addictions" share biological mechanisms with substance dependence, and "drug interactions" have been observed between certain substances and self-reinforcing behaviors. This study examines correlates of patterns of and motivations for playing video games while using or feeling the effects of a substance (concurrent use). Data were drawn from a nationally-representative survey of adu...

The development of concurrent object-oriented programs, from a software engineering perspective, must possess a set of features to allow control of its inherent complexities, such as non-determinism. This dissertation contributes the definition of an approach for constructing concurrent object-oriented programs. The approach is rooted in a divide-and-conquer strategy, in which functional and no...

Concurrent systems are often modeled using an interleaving semantics. Since system designers tend to think sequentially, it is highly probable that they do not foresee some interleavings that their model encompasses. As a consequence, one of the main sources of failure in concurrent systems is unforeseen interleavings. In this paper, we devise an automated method for revealing unforeseen interl...

Due to the importance of distribution, object technologies, and the Web, infrastructures for Distributed Object Computing and Component-based middleware have become common place. However, it is not sufficient to just read the specification of standards such as Java RMI, EJB, or CORBA, and then to build applications using these standards. On one hand the transparency provided by these platforms ...

Structural relation patterns have been introduced recently to extend the search for complex patterns often hidden behind large sequences of data. This has motivated a novel approach to sequential patterns post-processing and a corresponding data mining method was proposed for Concurrent Sequential Patterns (ConSP). This article refines the approach in the context of ConSP modelling, where a com...

Concurrency is unavoidable in modern software development, owing to the increasing complexity of computer systems and the widespread use of parallel computer hardware. Conventional approaches to concurrency are fraught with danger: in particular, uncontrolled access to shared resources, poor scalability and the inability of the programmer to reason about the correctness of a program. Process-or...
