Applying document clustering techniques to multidocument summarization is a challenging problem, mostly because of the redundancy that exists in multiple sources. We compare several document clustering techniques for multi-document summarization in the NTCIR-4 TSC test collection. We conducted an experiment to evaluate the effectiveness of reducing redundancy in the production of summaries. Fro...

INTRODUCTION: Supply chains face various disruptions from human-made to natural disasters preventing proper flow of materials and products. This problem is more important in the healthcare supply chains, especially the blood supply chains, in which human lives are at risk. Making the supply chains resilient, recently addressed by managers and researchers, can be a good way to tackle them. This ...

Achieving high-availability in service-oriented systems is a challenge due to the distributed nature of the architecture. Redundancy, using replicated services, is a common software strategy for improving the availability of services. However, traditional replication strategies are not appropriate for service-oriented systems, where diverse services may be grouped together to provide redundancy...

When people learn that I study lethal injection, they are usually curious to know more (or at least they are polite enough to ask questions). Interestingly, the question that arises most often— from lawyers, law students, and laypeople—is why states behave as they do. In the wake of botched executions and ample evidence of lethal injection‘s dangers, why do states fail to address their executio...

A student, supported by his classmates, throws a piece of chalk at the teacher who is writing on the blackboard. The teacher rapidly turns back and promptly catches him in the act. The student blushes and suddenly realizes how bad it was what he did. What happened to the guy? Why did he decide to throw the piece of chalk? And why, after a few seconds, he would have liked that what he did had ne...

Nowadays, university students suffer from a broad range of problems, such as educational underachievement or the inability to control themselves, that lead to procrastination as a consequence. The present research aimed at analyzing the determinants of decisional procrastination among undergraduate students and at assessing a path model in which self regulated learning strategies mediated the r...
