Mixed martial arts (MMA) fighting in a competition is not necessarily wrong and is often, as far as we can tell, permissible. Our argument has two premises. First, if an act does not infringe on anyone's moral right or violate another side-constraint, then it is morally permissible. Second, MMAviolence does not infringe on anyone's moral right or violate another sideconstraint. The first premise rests on two assumptions. First, if a person does a wrong act, then he wrongs someone. Second, if one person wrongs a second, then the first infringes on the second's right. We then look at Nicholas Dixon's powerful Kantian argument that MMA fighting is wrong.
Research Summary#.,Our objective in this project was to investigate the bioenergetics and physiology of high temperature bacteria. The initial focus was on a hyperthermophilic chemolithotroph, Pyrodictitim brockii (Stetter et al., 1983;Parameswaran et al., 1988; Pihl et al., 1989). This bacterium was chosen for several reasons: it has the reported highest optimum growth temperature (105 0 C) for any organism and it clearly reduces sulfur to sulfide to fulfill some or all of its energetic requirements. Although small amounts of yeast extract stimulate growth, growth proceeds mainly through hydrogen/sulfur autotrophy apparently centered around a series of electron transfer reactions in the cell membrane (Pihl et al., 1989; Pihl et al., 1990). Initially, based on the work on less thermophilic archaebacteria (Danson, 1988), we thought that the absence of significant heterotrophy would simplify the analysis of energetics and allow us to follow growth stoichiometry through gas analysis (i.e., by following the patterns of utilization of CO 2 , H2 and polysulfides, and production of H 2 S). An additional objective was to correlate membrane permeability with changes in energetic efficiency at different temperatures for the bacterium; the hypothesis is that the membranes of high temperature bacteria might be relatively permeable creating an energetic burden (McKay et al., 1982).Continuous culture techniques, developed for P. furiosus (Brown and Kelly, 1989), were modified to grow P. brockii under sulfur-or hydrogen-limiting conditions. Methods for feeding suspensions of colloidal sulfur or polysulfides were developed and a technique to measure cell membrane permeability was adapted to high temperature. Considerable effort was directed at determining the stoichiometry of hydrogen/sulfur autotrophy . However, after much effort, it was found that difficulties in obtaining sufficiently quantitative data for determining maximal yields and maintenance requirements on hydrogen and sulfur made pursuing the planned study infeasible. Also, extremely low biomass yields (2E7 cells/ml corresponding to approximately 5 mg/l cell dry weight) available for proton motive force and membrane permeability measurements and determination of important enzyme activities caused us to re-assess our choice of bacterium for study.As an alternative, we switched to Pyrococcus furiosus, an organism with which we had considerable experience. In many ways, this has proved to be a much better system for study, particularly in view of reproducibility of growth experiments and biomass yields. Also, some details of P. furiosus's physiology have been worked out and a growing list of enzymes from this bacterium have been purified and studied (e.g., Adams, 1990;Aono et al., 1989;Blumentals et al., 1990;Brown et al., 1990; Brown and Kelly, in preparation;Bryant and Adams, 1989;Connaris et al., 1991;Costantino et al., 1990; Blumentals et al., in preparation;Eggen et al., 1990;Koch et al., 1990; Klingeberg et al., 1991). We have been able to use many of the techniq...
Everyone has a different explanation for James Joyce. Thornton Wilder says he is a man divided between a violent love and a violent hate, “a love that cannot integrate its hate” and “a hate that cannot integrate its love”, a love and a hate for the land and the people he left but was unable ever to forget. Harry Levin, insofar as he attempts at all to explain, places great emphasis on Joyce's youthful theory of the development of the arts as a progress from the lyric, through the epic, to the dramatic. Barry Bymo agrees with the importance of this literary theory and suggests that Joyce's problem was the incompatibility between his artistic program and his own capabilities. Gorman, offering us his idol, does not explain Joyce at all except in terms of his high integrity, superb intellect, and remarkable fortitude—an explanation based for the most part on Joyce's own declarations to these effects. And Gogarty, antipathetic, seemingly resentful, attributes Joyce's development to the inherent arrogance which led him to reject his religion but never released him from fears of the consequences of this rejection. Gogarty therefore singles out as the crucial trauma from which Joyce never recovered and toward which he never ceased to react, the sermon on Damnation, Hell, and Eternity which he heard at Belvedere College when he was eleven years old.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
