Abstract Bacon, P. J., Gurney, W. S. C., McKenzie, E., Whyte, B., Campbell, R., Laughton, R., Smith, G., and MacLean, J. 2011. Objective determination of the sea age of Atlantic salmon from the sizes and dates of capture of individual fish. – ICES Journal of Marine Science, 68: 130–143. The sea ages of Atlantic salmon indicate crucial differences between oceanic feeding zones that have important implications for conservation and management. Historical fishery-catch records go back more than 100 years, but the reliability with which they discriminate between sea-age classes is uncertain. Research data from some 188 000 scale-aged Scottish salmon that included size (length, weight) and seasonal date of capture on return to the coast were investigated to devise a means of assigning sea age to individual fish objectively. Two simple bivariate probability distributions are described that discriminate between 1SW and 2SW fish with 97% reliability, and between 2SW and 3SW fish with 70% confidence. The same two probability distributions achieve this accuracy across five major east coast Scottish rivers and five decades. They also achieve the same exactitude for a smaller recent dataset from the Scottish west coast, from the River Tweed a century ago (1894/1895), and for salmon caught by rod near the estuary. More surprisingly, they also achieve the same success for rod-caught salmon taken at beats remote from the estuary and including capture dates when some fish could have been in the river for a few months. The implications of these findings for fishery management and conservation are discussed.

Warren F. Kuehl's list of United States and Canadian doctoral dissertations in history is an important American bibliographical reference work which no historian can afford to neglect. Yet, scholars of the history of the Habsburg monarchy find it difficult to make effective use of this valuable bibliography, for the bulk of the entries which are of potential interest to specialists in the field are listed under numerous subdivisions and are not consolidated under appropriate headings in the topical index. For instance, numerous dissertations dealing with nineteenth-century alliances, with multilateral negotiations involving the Austrian empire, such as the Congresses of Vienna, Paris, and Berlin, or with the diplomatic relations of the Habsburg monarchy and the Austrian Republic with neighboring states are listed under such diverse headings as “Eastern Question,” “Europe, Diplomacy,” “Alliance System and Concert of Europe,” or “Near East.” While most scholars use library catalogs largely for finding works written by particular authors, those who peruse dissertation lists are more often interested in ascertaining what has been written on specific topics.

Determinism And Indeterminism

This article focuses on three themes concerning determinism and indeterminism. The first is observational equivalence between deterministic and indeterministic models. The article discusses several results about observational equivalence and presents an argument on how to choose between deterministic and indeterministic models involving indirect evidence. The second is whether Newtonian physics is indeterministic. The article argues that the answer depends on what one takes Newtonian mechanics to be and highlights how contemporary debates on this issue differ from those in the nineteenth century. The third theme is how the method of arbitrary functions can be used to make sense of deterministic probabilities. The article discusses various ways of interpreting the initial probability distributions and argues that they are best understood as physical, biological, and other quantities characterizing the particular situation. The fact that the method of arbitrary functions deserves more attention than it has received so far is also emphasized.
