Systematic tail risk is considered an important determinant of expected returns on risky assets. We examine its impact from two perspectives in a unified framework which originates simple asset pricing model.

Lutein and zeaxanthin are thought to decrease the incidence of age-related macular degeneration (AMD); however, findings have been inconsistent. We conducted a systematic literature review and meta-analysis to evaluate the relationship between dietary intake of lutein and zeaxanthin and AMD risk. Relevant studies were identified by searching five databases up to April 2010. Reference lists of a...

Microbial contamination is of critical importance when it comes to production processes, especially in the pharmaceutical industry. Avoidance of microbial contamination throughout production processes is therefore crucial. However, what are the essentials of an effective hygiene regime? And what kind of hygiene measures are to be taken in order to be safe and effective? This work demonstrates h...
