Ziel der Diplomarbeit ist es, einerseits den Ökotextilmarkt hinsichtlich der eingesetzten Rohstoffe, der angebotenen Produkte und deren Zertifizierungen darzustellen. Andererseits wurden die bisherigen Entwicklungen des Ökotextilmarktes, die Entwicklungschancen von Naturfasern aus...

Ecological resources are resources that have functional value to ecosystems. Frequently, these functions are overlooked in terms of the value they provide to humans. Environmental economics is in search of an appropriate analysis framework for such resources. In such a framework, it is essential...

In ecological population management, years of animal counts are fit to nonlinear, dynamic models (e.g. the Ricker model) because the values of the parameters are of interest. The yearly counts are subject to measurement error, which inevitably leads to biased estimates and adversely affects...

One of the assumptions of analysis of variance (ANOVA) is that the variances of the groups being compared are approximately equal. This assumption is routinely checked before doing an analysis, although some workers consider ANOVA robust and do not bother and others avoid parametric procedures...

E tanulmány azt vizsgálja, hogy a fenntartható fejlődés közgazdasági fogalmát miképpen lehet hatékonyan bevezetni a köznevelésbe és az iskolán kívüli nevelési tevékenységbe. A fenntartható fejlődésre úgy tekintünk, mint gazdasági, társadalmi és környezetvédelmi...

The Bayes factor is commonly used for comparing different evolutionary rate models and different topologies in phylogeny. It is crucial to develop efficient Monte Carlo methods for estimating the marginal likelihoods in the Bayes factor. The Monte Carlo methods currently advocated in the...

The effectiveness of SO{sub 2} emission allowance trading under Title 4 of the 1990 Amendments to the Clean Air Act (CAA) is of great interest due to the innovative nature of this market incentive approach. However, it may be a mistake to frame the compliance problem for a utility as a decision...

This paper deals with the market for SO{sub 2} emission allowances over time and electric utility compliance choices. For currently high emitting plants ( 2.5 lb SO{sub 2}/MMBtu), the 1990 Clean Air Act Amendments (CAAA) provide for about twice as many SO{sub 2} allowances to be issued per year...
