With the INTEGRAL observatory, ESA has provided a unique tool to the astronomical community revealing hundreds of sources, new classes of objects, extraordinary views of antimatter annihilation in our Galaxy, and fingerprints of recent nucleosynthesis processes. While INTEGRAL provides the global overview over the soft gamma-ray sky, there is a growing need to perform deeper, more focused inves...

We study institutional entrepreneurship in an emergent field by analyzing the case of the Global Reporting Initiative (GRI) and its efforts to purposefully institutionalize the practice of sustainability reporting. We suggest that analogies affect institutionalization processes through two mechanisms. In the early stages of institutionalization, analogy operates primarily as a normative mechani...

This paper reviews some of the econometrics problems faced when estimating a rational addiction model of Becker and Murphy (1988) using panel data. This is illustrated with three empirical applications. The …rst application looks at cigarette consumption using macro panel data on American states over time (see Baltagi and Gri¢ n (2001)). The second application looks at liquor consumption using ...

Response of five induced plant height mutants (dwarfs and semi-dwarfs) of barley to gibberellic acid (GA3) treatment was studied. The gibberellic acid response index (GRI) was calculated and based on this value, the mutants have been categorized as sensitive (high or moderate) or insensitive. The GRI value was highest for dwarf mutant followed by early maturing mutant with the former being high...

In light of the growing demand for sustainable behavior and the special interest that has emerged regarding the social and environmental impact of firms, the purpose of this research is to analyze the determinants of the accounting treatment of emission rights. To achieve that purpose, we use a sample composed of 119 firms worldwide from different countries and activity sectors for the period 2...

To frame and motivate the goals pursued in the present article we recall that, loosely speaking, the most common among the blowup algebras are the Rees algebra R[It] = ⊕∞ n=0 I ntn and the associated graded ring grI(R) = ⊕∞ n=0 I n/In+1 of an ideal I in a commutative Noetherian local ring (R,m). The three main clusters around which most of the current research on blowup algebras has been develo...
