Variabilità fonetico-sintattica nella Commercial Contemporary Music come oggetto di studio per le classi avanzate di inglese come L2

The aim of this research is to set up a consistent theorical arrangement concerning the socio-linguistic and socio-phonetic aspects of contemporary commercial music (CCM), which appears to be more and more uneven and manifold, also taking into account the previous research by Trudgill (1983), Simpson (1999) and others. The massive use of phonetic variation and style switching in contemporary Western singing style is here analyzed mainly focussing on its phonetic, cognitive and semantic relevance. Some examples of metric, socio-linguistic and stylistic variation are provided afterwards, so that a global diagram of linguistic habits might be traced. Other collateral aspects are recollected, mostly concerning the effects of CCM experience on L2 users.

Time-varying relationship between corporate governance and expected stock returns

This paper aims to analyze a time-varying relationship between corporate governance and expected stock returns in Thailand. The time variation of corporate governance premium is estimated by macroeconomic determinants using a two-state Markov switching model. The results indicate the presence of asymmetries in the variations of corporate governance premium over the Thai economic cycles. Investors can take advantage of the time-varying characteristics with the adaptation of switching investment strategy. Incorporation of style switching strategy with value premium in recessions and momentum premium in expansions improves expected returns of corporate governance-sorted portfolios.

On the Style-Based Feedback Trading of Mutual Fund Managers

This paper examines the style-based feedback trading behavior of U.S. mutual fund managers. We provide an empirical version of Barberis and Shleifer’s style-switching model. We find style-based feedback trading for 77% of the funds, half of which is positive (negative) feedback trading. There is evidence for “twin style” switching, where capital is channeled between value and growth, and between large- and small-cap. Growth (value) funds apply more positive (negative) feedback trading. Funds that switch more aggressively are younger and have higher expense ratios. Finally, we find that positive (negative) feedback trading yields positive (negative) alpha.

Modeling Style Rotation: Switching and Re-switching

The purpose of this paper is to investigate the dynamics and statistics of style rotation based on the Barberis–Shleifer model of style switching. Investors in stocks regard the forecasting of style-relative performance, especially style rotation, as highly desirable but difficult to achieve in practice. Whilst we do not claim to be able to do this in an empirical sense, we do provide a theoretical framework for addressing these issues. We develop some new results from the Barberis–Shleifer model which allows us to understand some of the time series properties of styles’ relative performance and determine the statistical properties of the time until a switch between styles. In conclusion, we discuss potential applications of our findings to empirical data.
