Biocentrism environmental ethicists and animal rights defenders have been articulating ethical principles to extend moral standing to nonhuman beings. The natural propensities of living beings to pain and pleasure, being a subject of life, and having specific good and interest (as proposed by Singer, Regan, Tayler, and Goodpaster, respectively), have been taken as a reason to determine the moral status of the beings in question. This article makes the case that none of them can offer all-inclusive ideal for biocentrism to (...) embrace all life forms as moral patients since they are either exclusive, hierarchical, or imprecise. To this end, I argue that it is possible to drive a unifying ideal from Schopenhauer’s metaphysics: the will to live. The will to live is a quality that all living beings share, regardless of their abilities and propensities. Both conscious and unconscious beings, sentient and non-sentient creatures, lower animals and plants are the embodi­ments or physical forms of the ultimate reality that is the will to live. Thus, biocentrism becomes more valid and effective in environmental preservation by incorporating the will to live into its ethical principle. (shrink)

The risky investment game of Gneezy and Potters :631–645, 1997) has been proposed as a simple tool to measure risk aversion in applied settings, especially attractive in settings where participants may have limited education. However, this game can produce a significant endowment effect, so that analysis of the behavior in this game should not be done in the Expected Utility Theory framework. The paper illustrates this point, by showing that risk tolerance can be much higher when the initial endowment concerns (...) a risky lottery. (shrink)

The complex hexaploid wheat genome offers many challenges for genomics research. Expressed sequence tags facilitate the analysis of gene-coding regions and provide a rich source of molecular markers for mapping and comparison with model organisms. The objectives of this study were to construct a high-density EST chromosome bin map of wheat homoeologous group 2 chromosomes to determine the distribution of ESTs, construct a consensus map of group 2 ESTs, investigate synteny, examine patterns of duplication, and assess the colinearity with rice (...) of ESTs assigned to the group 2 consensus bin map. A total of 2600 loci generated from 1110 ESTs were mapped to group 2 chromosomes by Southern hybridization onto wheat aneuploid chromosome and deletion stocks. A consensus map was constructed of 552 ESTs mapping to more than one group 2 chromosome. Regions of high gene density in distal bins and low gene density in proximal bins were found. Two interstitial gene-rich islands flanked by relatively gene-poor regions on both the short and long arms and having good synteny with rice were discovered. The map locations of two ESTs indicated the possible presence of a small pericentric inversion on chromosome 2B. Wheat chromosome group 2 was shown to share syntenous blocks with rice chromosomes 4 and 7. (shrink)
