Scientific journals have a central place in protecting research integrity because published articles are the most visible documentation of research. We used SWOT analysis to audit (S)trengths and (W)eaknesses as internal and (O)pportunities and (T)hreats as external factors affecting journals' responsibility in addressing research integrity issues. Strengths include editorial independence, auth...

The Croatian Medical Journal (CMJ), as a small journal that is not part of any publishing group faces serious challenges to prosper in a multitude of diverse biomedical journals. In such a complex situation, adaptations are always necessary. They include changing the editorial policy, embracing new ideas, and introducing new members to the Managing Team. Besides selecting the right articles, ex...

Reinforcement Learning methods based on approximating dynamic programming (DP) are receiving increased attention due to their utility in forming reactive control policies for systems embedded in dynamic environments. Environments are usually modeled as controlled Markov processes, but when the environment model is not known a priori, adaptive methods are necessary. Adaptive control methods are ...

Virtual communities (VCs) are socio-technical systems wherein distributed individuals (human and/or artificial) are grouped together around common objectives and goals [10, 6]. In such systems, participants are massively collaborating with each others by sharing their private resources and knowledge. A collaboration always bears the risk that one partner exhibits uncooperative or malicious beha...

In this paper, we present a formal model, named PobSAM (Policy-based SelfAdaptive Model), for developing and modeling self-adaptive evolving systems. In this model, policies are used as a mechanism to direct and adapt the behavior of self-adaptive systems. A PobSAM model is a collection of autonomous managers and managed actors. The managed actors are dedicated to the functional behavior while ...

Adaptive systems improve their efficiency by modifying their behaviour to respond to changes in their operational environment. Also, security must adapt to these changes and policy enforcement becomes dependent on the dynamic contexts. We study these issues within MLCoDa, (the core of) an adaptive declarative language proposed recently. A main characteristic of MLCoDa is to have two components:...

Feedback Control Loops (FCLs) are the heart of any self-adaptive system. Existing engineering approaches for building self-adaptive systems mask FCL by providing abstraction layers that hide the application complexity. In this paper, we investigate a model-driven approach for the engineering of FCLs whose architecture is based on the Service Component Architecture (SCA) model. Our proposal cons...

When carrying Internet Protocol (IP) traffic over an Asynchronous Transfer Mode (ATM) network, the ATM adaptation layer must determine how long to hold a virtual circuit opened to carry an IP datagram. In this paper we present a formal statement of the problem and carry out a detailed empirical examination of various holding time policies taking into account the issue of network pricing. We off...
