In this study Amplified Fragment Length Polymorphism (AFLP) was applied to species identification of bester hybrids. Hybrids identification was performed by comparison of electrophoresis profiles with parental species. The simultaneous occurrence of diagnostic bands fixed in the parental species, genetic distance and identification and cluster analyses (UPGMA) allow a correct identif...

In a convincing analysis of the conditions and strength of altruism, Bester and Güth [Journal of Economic Behavior & Organization, Vol. 34, 1998, 193-209] unfortunately restrict the interpretation of their results. Their paper provides us with an analysis of the conditions and strength of malevolence (or envy) as well. ©2000 Elsevier Science B.V. All rights reserved. JEL classification: A13; C7...

in order to determine the most effective hormones on the in vitro oocyte maturation (germinal vesicle breakdown - gvbd) in a hybrid sturgeon bester, ovarian follicles were incubated at the migratory nucleus stage in the presence of several steroids, gonadotropin preparations and forskolin. occurrence of gvbd and 17,20β-dihydroxy-4-pregnen-3 -one (dhp) production were followed during an expe...

During the past three decades, every aspect of cardiomyopathy has undergone dramatic change. When examining the literature on the physiological aspects of the failing heart, one immediately recognises that South Africa has made a contribution: Brink, Bester and Lochner evaluated the possible therapeutic aspects of the Bowditch phenomenon and myocardial energetics in cardiomyopathy almost four d...

Bester, a hybrid sturgeon (Huso huso L. females ´ Acipenser ruthenus L. males), neither spermiate nor ovulate in the captivity. Thirteen-year-old adult male and female bester were injected with LH-RHa (0.1-0.3 mg/kg B.W.) intramuscularly and spawning status of the treated fish was checked 24-48 hours later. Additionally, changes in serum levels of DHP in both the responded and the non-responded...

We consider mechanism design problems with n agents when the mechanism designer cannot fully commit to an allocation function. With a single agent (n 5 1) optimal mechanisms can always be represented by direct mechanisms, under which each agent’s message set is the set of his possible types [Bester, H., Strausz, R., 2000. Contracting with imperfect commitment and the revelation principle: the s...
