Machine Learning (ML) algorithms have opened up new possibilities for the acquisition and processing of documents in Information Retrieval (IR) systems. Indeed, it is now possible to automate several labor-intensive tasks related to documents such as categorization and entity extraction. Consequently, the application of machine learning techniques for various large-scale IR tasks has gathered s...

Crowdsourcing contests—events to solicit solutions to problems via an open-call format for prizes—have gained ground as a mechanism for organizations to accomplish tasks. This paper uses game-theoretic models to develop design principles for crowdsourcing contests and answer the questions: what types of tasks should be crowdsourced? Under what circumstances? When a single task is to be complete...

Designing mixed criticality real-time systems raises numerous challenges. In particular, reducing their energy consumption while enforcing their schedulability is yet an open research topic. To address this issue, our approach exploits the ability of tasks with low-criticality levels to cope with deadline misses. On multiprocessor systems, our scheduling algorithm handles tasks with high-critic...

This paper explores how open-mindedness and its exercise can be social in nature. In particular, it argues that an individual regarded as open-minded even though she does not conduct all of the intellectual tasks required by herself; is, delegates some these to her epistemic peers. Thinking about such terms only opens up possibility there are different surprising ways for open-minded, but also ...

The scarcity of talent is a tremendous challenge for firms in the globalized world. This paper investigates the role of labor market imperfection in open economies for the usage of talent in the production process of firms. For this purpose, I set up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low-skilled and high-skilled ...

The management of the corporate information technology (IT) environment is rapidly increasing in complexity as server logic architecture becomes more distributed and the number of entities deployed increases, forcing enterprises to resort to thick, complex and expensive high-end integrated systems and network management solutions. Investing in such systems can be ineffi cient for small and medi...

This study was an attempt to investigate what metacognitive strategies are specifically employed by English learners when it comes to different speaking task types.60 students at advanced level (female) were randomly selected and given an OPT as a test of homogeneity. They were assigned to experimental and control groups. The MS questionnaire (Oxford, 1990) was also administered to see what MS ...
