Two agarolytic strains of Gram-negative, heterotrophic, facultatively anaerobic, marine bacteria, designated AAM1T and AAT1T, were isolated from seawater samples collected in the shallow coastal region of An-Ping Harbour, Tainan, Taiwan. Cells grown in broth cultures were straight rods that were motile by means of a single polar flagellum. The two isolates(More)
A Gram-negative, heterotrophic, agarolytic, marine bacterium, designated strain SA1T, was isolated from a seawater sample collected in the shallow coastal region of Keelung, Taiwan. Cells were straight to slightly curved rods. Nearly all of the cells were non-motile and non-flagellated during the exponential phase of growth in broth cultures; a few cells(More)
A marine agarolytic bacterium, designated strain TMA1(T), was isolated from a seawater sample collected in a shallow-water region of An-Ping Harbour, Taiwan. It was non-fermentative and Gram-negative. Cells grown in broth cultures were straight or curved rods, non-motile and non-flagellated. The isolate required NaCl for growth and exhibited optimal growth(More)
This paper relates variation in stock market volatility to regime shifts in stock market returns. We apply a Markov switching model to market returns and examine the variation in volatility in different return regimes. We find that stock returns are best characterized by a model containing six regimes with significantly different volatility across the(More)
The ability to conduct hypothesis tests is among the most important statistical skills that our students can learn. Unfortunately, it is also one of the most difficult skills for them to learn. In our survey of 44 introductory business and economics statistics textbooks, we find that textbook authors differ over the better way to explain one-tailed(More)
The stability of electricity prices: estimation and inference of the Lyapunov exponents The views expressed are those of the author and do not necessarily reflect the views of the Bank of Finland. Abstract The aim of this paper is to illustrate how the stability of a stochastic dynamic system is measured using the Lyapunov exponents. Specifically, we use a(More)
