We describe and analyse how large herbivores strongly diminished a woody vegetation, dominated by the unpalatable shrub Sambucus nigra L. and changed it into grassland. Density of woody species and cover of vegetation were measured in 1996, 2002 and 2012 in the grazed Oostvaardersplassen. In 2002 and 2012 we also measured density and cover in an ungrazed control site. In 2002 we measured intensity of browsing and bark loss of Sambucus shrubs in the grazed and control sites. In the grazed (...) site the density of Sambucus and Salix spp. declined significantly between 1996 and 2012, and large areas changed into grassland. In the control site the density of Sambucus increased significantly during this period, the density of Salix spp. did not change, and the vegetation consisted of a mixture of woody species and a field layer dominated by tall herbs. In 2002 and 2012 the percentages of dead Sambucus shrubs were significantly higher in the grazed site than in the control site. In 2002 the percentages of twigs browsed and ring barked stems of Sambucus shrubs were significantly higher in the grazed site than in the control site. Our results show that debarking caused mature Sambucus shrubs to die, but that heavy browsing may have helped this process. Our results also point to a significant neighbour effect on the break down of Sambucus, suggesting that Aggregational Resistance and Associational Palatability were both active. Essential conditions for the break down of this woody vegetation were the presence of large herbivores, the low ratio between the areas of summer and winter feeding habitats and the competition amongst herbivores. Browsing may have been responsible for seedling death, as seedlings were found only in the control site and not on the old and newly established grasslands in the grazed site. (shrink)

We analyse the extent of possible computations following Hogarth ([2004]) conducted in Malament–Hogarth (MH) spacetimes, and Etesi and Németi ([2002]) in the special subclass containing rotating Kerr black holes. Hogarth ([1994]) had shown that any arithmetic statement could be resolved in a suitable MH spacetime. Etesi and Németi ([2002]) had shown that some relations on natural numbers that are neither universal nor co-universal, can be decided in Kerr spacetimes, and had asked specifically as to the extent of computational limits there. (...) The purpose of this note is to address this question, and further show that MH spacetimes can compute far beyond the arithmetic: effectively Borel statements (so hyperarithmetic in second-order number theory, or the structure of analysis) can likewise be resolved: Theorem A. If H is any hyperarithmetic predicate on integers, then there is an MH spacetime in which any query ? n H ? can be computed. In one sense this is best possible, as there is an upper bound to computational ability in any spacetime, which is thus a universal constant of that spacetime. Theorem C. Assuming the (modest and standard) requirement that spacetime manifolds be paracompact and Hausdorff, for any spacetime there will be a countable ordinal upper bound, , on the complexity of questions in the Borel hierarchy computable in it.

The Limits of the Formal Treatment of Language. Within the philosophy of language, there is a distinction between the natural language philosophers and the ideal language philosophers. The distinction is drawn based on the way these philosophers reflect on language and the world. Natural language philosophers stress the context-based feature of meaning, while the ideal language philosophers emphasize the context-free feature of meaning. In my study I want to show that that even within the formal study of language, in the (...) apparent absence of any context, the notions of valuation and interpretation help us to understand the meaning of sentences.

An edition of the letters of Erasmus, regarded as one of the greatest humanist writers. All 12 volumes of this work have been reissued, complete with their scholarly apparatus of commentary and notes, as well as plates.

We characterize strict Mittag-Leffler modules in terms of free realizations of positive primitive formulas, and rings over which projectives are trivial in terms of various notions of separability of strict Mittag-Leffler modules. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The words I wish to delete in 48-9 spoil a ‘tricolon crescendo’ whose three members are clearly marked and whose verbs are perhaps deliberately varied in person and tense. The parataxis by means of hic is awkward, and the words seem to be a versified gloss. The Scholiast says : id est: to nobilis tantum et imperitus. nam de plebe, id est de humili familia, eloquentes exeunt, qui nobilium imperitorum causas defendunt; but that could be a paraphrase based on the (...) text as it stands in our manuscripts.

SummaryThe Gricean maxims of conversation are regulated by a supermaxim which determines what is relevant or not for a particular conversation. This maxim, involving a pragmatical knowledge, imposes specific restrictions on conversational strategy. It is called the “maxim of conversation topology” because it fixes the topos of a conversation.RésuméDans cet article nous démontrons que les maximes de la conversation, établies par H.P. Grice, sont dominées par une supermaxime qui détermine ce qui est pertinent et ce qui n'est pas pertinent pour (...) une certaine conversation. Cette maxime, qui implique une connaissance ?on;ordre pragmatique, impose des restrictions spécifiques sur la stratégie de conversation. Cette supermaxime, axiomatiquement premiére, est appelée ici la maxime de la topologie de la conversation, puisque c'est elle qui fixe le topos?on;une conversation.ZusammenfassungDie Maximen, die Grice für die Durchführung einer Konversation aufstellt, werden ihrerseits durch eine Obermaxime geregelt, die bestimmt, was für eine gegebene Konversation relevant ist oder nicht. Die Maxime involviert pralctisches Wissen und legt der angewendeten Strategie spezifi‐sche Einschränkungen auf. Sie wird die Maxime der Konversationstopologie genannt, weil sie den Topos einer Konversation festlegt. (shrink)

A review of a conference meeting focused on the philosophy of religion.

ASD VI,7 comprises Erasmus's Annotations on Paul's Epistole to the Romans. Many subjects with respect to, for instance, justification by faith and the relation between Jews and Christians are treated. Hovingh comments on Erasmus's commentary, identifying his sources and his stilistic and grammatical peculiarities.

IN this note I propose to make some general remarks concerning the analytical forays carried out into moral discourse by some leading figures in the modern ‘linguistic’ tradition. The philosophers I am going to speak of, may all be said to be attempting some sort of ‘descriptive’ analysis, but my thesis is that philosophers such as Toulmin and Baier are attempting something that is significantly different from what a philosopher such as Nowell-Smith is attempting. I will suggest, in the following (...) section, that the expression—‘the logic of moral discourse’—seems to be understood by these two groups of linguistic philosophers in two different ways and that one of these ways involves a more ambitious claim, than does the other, on behalf of the philosopher embarking upon a conceptual analysis of moral discourse. The manner in which, it seems to me, Toulmin and Baier understand this expression is the one that involves the more ambitious claim. In the final section of this paper I suggest that the more ambitious claim involves overloading the so-called Linguistic method to force it do a job that it seems at least not suited to perform.
