An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria

The Marine Stewardship Council (MSC) has established a program whereby a fishery may be certified as being sustainable. The sustainability of a fishery is defined by MSC criteria which are embodied in three Principles: relating to the status of the stock, the ecosystem of which the stock is a member and the fishery management system. Since many of these MSC criteria are comparable for global tuna stocks, the MSC scoring system was used to evaluate nineteen stocks of tropical and temperate tunas throughout the world and to evaluate the management systems of the Regional Fishery Management Organizations (RFMO) associated with these stocks

Study of aerodynamic technology for single-cruise engine V/STOL fighter/attack aircraft

A conceptual design analysis is performed on a single engine V/STOL supersonic fighter/attack concept powered by a series flow tandem fan propulsion system. Forward and aft mounted fans have independent flow paths for V/STOL operation and series flow in high speed flight. Mission, combat and V/STOL performance is calculated. Detailed aerodynamic estimates are made and aerodynamic uncertainties associated with the configuration and estimation methods identified. A wind tunnel research program is developed to resolve principal uncertainties and establish a data base for the baseline configuration and parametric variations

Ad Hominem Arguments

Ad hominem arguments (in one sense) argue that some opponent should not be heard and no argument of that opponent should be heard or considered. The opponent has generally pernicious views, false and harmful. Moreover he is diabolically clever at arguing for his views. Thus, the ad hominem argument is essentially a device by which non-intellectuals try to wrest control of a dialectical situation from intellectuals. Stifling intellectuals, disrupting the dialectical situation, is an unpleasant conclusion, but no fallacy has been shown in what leads up to that conclusion

A problem in the one-fallacy theory

According to the one-fallacy theory, the only real fallacy is equivocation. In particular, the fallacy of incomplete evidence draws a conclusion inductively from parts of our evidence while ignoring other parts of it which undermine the conclusion. T his is an equivocation on the relative term \u27probable\u27: the conclusion is probable relative to a part of our evidence but not relative to the whole of it. Unfortunately, this view is not entirely consistent with my meta-theory of fallacies which allows t hat some failures of rationality are errors simply in inductive reasoning rather than being equivocations

Review of \u3ci\u3eDivining Margaret Laurence: A Study of Her Complete Writings\u3c/i\u3e By Nora Foster Stovel

Neil Besner is right to judge Nora Foster Stovel\u27s Divining highly: it ranges across all of Laurence\u27s work ... intelligently and accessibly, as he says on the jacket. Before I augment his praise I must note a couple of blemishes, if Stovel will accept the soft impeachment of an admirer. Malcolm Ross did not teach the future Margaret Laurence or anyone else at United College (now the University of Winnipeg): I was a student with Peggy Wemyss in Ross\u27s stunning Seventeenth-Century Thought on the Fort Garry campus of the University of Manitoba (and in spite of the uncorrected typo of photo #18, following p. 124, of my Alien Heart: The Life and Work of Margaret Laurence [2003]). More serious, Stovel repeats Donez Xiques\u27s misreading (in Margaret Laurence: The Making of a Writer [2005]) of Laurence\u27s early and impressive poem Pagan Point, where one notes the evident opposition of the unearthly paganism of Old Neptune ... and the ancient battle-voice of Thor to what replaced them. Peggy\u27s pagan gods are associated with the cry, / raucous and heathen, of a far-off loon, anticipating the loons heard by Piquette in A Bird in the House. Piquette belongs to the family Tonnerre (some Canadiens recognize that as the family of Thor) and might have been the only one, after all, who had heard the crying of the loons, also heard by Allie Chorniuk in Dance on the Earth who thinks but tonight their voices are silent -Homo sapiens is driving them away from the lakes, or killing them off . .. The thought ... hurts unbearably (quoted in Alien Heart, 449). The opposition here (which Stovel discerns) is also that of Pagan Point : the raucous and heathen loon versus the dim cathedral-full of rest, .... where Man may [sic] find his God. This is like the opposition to Tennyson\u27s meek and mild Lotos Eaters posed by Ulysses, whose aim was echoed in the motto of Peggy Wemyss\u27s high school: To strive, to seek, to find, and not to yield. The attitude of Blake ( Was Jesus gentle ... ? ), was familiar as well to Hagar\u27s creator. This misreading is almost as regrettable as identifying Henry James\u27s definition of the novel as a loose, baggy monster (Divining, 247), a phrase James used in his preface to The Tragic Muse as a critique of certain novels, not as a definition of the genre
