Despite consensus in focus on form (FOF) instruction over the facilitative role of noticing, controversy has not quelled over ways of directing EFL learners’ attention towards formal features via implicit techniques like input-enhancement or explicit metacognitive feedback and interactive peer-editing on the output they produce. This quasi-experimental study investigated the impact of input enh...

We show how several complex barrier options can be hedged using a portfolio of standard European options. These hedging strategies only involve trading at a few times during the option’s life. Since rolling, ratchet, and lookback options can be decomposed into a portfolio of barrier options, our hedging results also apply.

Despite the importance of hedging in academic productions, its use in different disciplines and genres has been given little attention (Hyland, 1998; Crystal, 1995). More precisely, the role of different genders as contributors to this social phenomenon (i.e., research articles) has been taken as neutral, as if gender is inconsequential in identity construction. The studies done in English sugg...

Aims. Devices that allow using the functionality of natural hand movements are of the greatest interest. The purpose of this study is to select areas of research at the intersection of several fields of science – biomechanics and cybernetics to develop scientific and technical approaches to track the movements of the operator's fingers and form feedback tactile and force communication received ...

Optimal asset allocation strategies of defined-contribution pension plans for members whose terminal utility is a power function of wealth-to-wage ratio is investigated in this paper. The portfolio problem is to maximize the expected terminal utility in the presence of three risk sources, interest risk, asset risk and wage risk. A closed form solution is found for the asset allocation problem a...
