This paper analyzes two pixel-based classification approaches to support the analysis of land cover transformations based on multitemporal LANDSAT sensor data covering a time space of about 24 years. The research activity presented in this paper was carried out using Lama San Giorgio (Bari, Italy) catchment area as a study case, being this area prone to flooding as proved by its geological and hydrological characteristics and by the significant number of floods occurred in the past. Land cover classes were defined in accordance with on the CN method with the aim of characterizing land use based on attitude to generate runoff. Two different classifiers, i.e. Maximum Likelihood Classifier (MLC) and Java Neural Network Simulator (JavaNNS) models, were compared. The Artificial Neural Networks (ANN) approach was found to be the most reliable and efficient when lacking ground reference data and a priori knowledge on input data distribution.

SUMMARY For the time stationary global geomagnetic field, a new modelling concept is presented. A Bayesian non-parametric approach provides realistic location dependent uncertainty estimates. Modelling related variabilities are dealt with systematically by making little subjective a priori assumptions. Rather than parametrizing the model by Gauss coefficients, a functional analytic approach is applied. The geomagnetic potential is assumed a Gaussian process to describe a distribution over functions. A priori correlations are given by an explicit kernel function with non-informative dipole contribution. A refined modelling strategy is proposed that accommodates non-linearities of archeomagnetic observables: First, a rough field estimate is obtained considering only sites that provide full field vector records. Subsequently, this estimate supports the linearization that incorporates the remaining incomplete records. The comparison of results for the archeomagnetic field over the past 1000 yr is in general agreement with previous models while improved model uncertainty estimates are provided.

Hume's sceptical arguments regarding induction have not yet been successfully answered. However, I shall not in this paper discuss the important attempts to answer Hume since that would be too lengthy a task. On the supposition that Hume's sceptical arguments have not been met, the empirical world is a place where, as the popular metaphor goes, all the glue has been removed. For the Humean sceptic, the only empirical knowledge that we can have is given to us in immediate perception. We have no reason to believe that the patterns of future events will in any way resemble patterns of events in the present or past. We have no reason to believe even that present events not observed resemble present events that are observed, or that knowledge of past and present can be any guide in making new discoveries about what took place in the past. What we have is an ideal setting for the calculation of a priori probabilities. We have a field of distinct events having no logical or evidential ties to one another. The attempt to justify induction that I wish to present is an appeal to a priori probability.

In order to provide textbook authors with empirical data on the acquisition in Dutch of written morphology in nouns, verbs and adjectives, several empirical studies have been undertaken. In this article, the third study reports on the performance of the morpheme -e in a special case of adjectives in Dutch: the adjectives derived from participles. The study tries to determine the possible interference between the morphological rules for verb inflection (past tense) and adjective declension in reading and writing. Five classes of adjectives were distinguished according to order of relative difficulty established a priori. Subjects (n=157, grade 6, 7 and 8 from two schools) individually completed a compre-hension and a production task in which factors were systematically varied. Also a recognition test on the spelling of the past tense of verbs was administered. The results showed an effect of categories of verbal adjectives in the production task, but only for groups 7 and 8; group 6 was not sensitive to the differences between the categories. In the recognition task, no effect of type of adjective (verbal or normal) was found for groups 7 and 8; but for group 6, performance on verbal adjectives was lower for the three most difficult categories of adjectives. In the production task, all three groups performed lower on verbal adjectives than normal adjectives in the two most difficult categories of adjectives. It turned out that groups which acquired spelling rules for the past tense of verbs to a higher level, made more errors in the spelling of verbal adjectives, especially in the two categories of adjectives which related the strongest to the spelling of verbs. It was concluded that indications were found that negative transfer or interference is present. Authors recommend changing the order of phases in which spelling rules are trained: from 'adjective declension-verb inflection (past tense)-verbal adjective declension' to 'adjective declension (including verbal adjective declension)-verb declension (past tense).

Artificial languages—languages which have been consciously designed—have been created for more than 900 years, although the number of them has increased considerably in recent decades, and by the early 21st century the total figure probably was in the thousands. There have been several goals behind their creation; the traditional one (which applies to some of the best-known artificial languages, including Esperanto) is to make international communication easier. Some other well-known artificial languages, such as Klingon, have been designed in connection with works of fiction. Still others are simply personal projects. A traditional way of classifying artificial languages involves the extent to which they make use of material from natural languages. Those artificial languages which are created mainly by taking material from one or more natural languages are called a posteriori languages (which again include well-known languages such as Esperanto), while those which do not use natural languages as sources are a priori languages (although many a posteriori languages have a limited amount of a priori material, and some a priori languages have a small number of a posteriori components). Between these two extremes are the mixed languages, which have large amounts of both a priori and a posteriori material. Artificial languages can also be classified typologically (as natural languages are) and by how and how much they have been used. Many linguists seem to be biased against research on artificial languages, although some major linguists of the past have been interested in them.

Seeking goals carried out by agents with a level of competency requires an “understanding” of the structure of their world. While abstract formal descriptions of a world structure in terms of geometric axioms can be formulated in principle, it is not likely that this is the representation that is actually employed by biological organisms or that should be used by biologically plausible models. Instead, we operate by the assumption that biological organisms are constrained in their information processing capacities, which in the past has led to a number of insightful hypotheses and models for biologically plausible behaviour generation. Here we use this approach to study various types of spatial categorizations that emerge through such informational constraints imposed on embodied agents. We will see that geometrically-rich spatial representations emerge when agents employ a trade-off between the minimisation of the Shannon information used to describe locations within the environment and the reduction of the location error generated by the resulting approximate spatial description. In addition, agents do not always need to construct these representations from the ground up, but they can obtain them by refining less precise spatial descriptions constructed previously. Importantly, we find that these can be optimal at both steps of refinement, as guaranteed by the successive refinement principle from information theory. Finally, clusters induced by these spatial representations via the information bottleneck method are able to reflect the environment’s topology without relying on an explicit geometric description of the environment’s structure. Our findings suggest that the fundamental geometric notions possessed by natural agents do not need to be part of their a priori knowledge but could emerge as a byproduct of the pressure to process information parsimoniously.

Dr. Sidney Coupland, in opening the discussion, said: I need hardly say that I have read Dr. Gettings' paper with great interest, and have found it, as other readers must have done, very instructive as well as entertaining. What gives particular interest to his graphic story is the fact that it is based upon the continuous medical records of an institution for nearly a century, and in this respect it must surely be unique. From a remark in the paper, apparently more zeal in clinical note-taking was exhibited in the earlier than in the later period of the history of Wakefield Asylum, but I feel sure that, if this be so, the lapse can only be temporary. As regards dysentery, it is certainly remarkable that a disease, once fairly common in this country, should have almost entirely disappeared from the community at large, a disappearance which seems to have coincided with that of the last serious visitations of cholera in the middle of last century. Even if we accept the usual explanation that these diseases, like typhus, have been banished in consequence of wide-spread improvement in urban and rural sanitation, especially as regards drainage and water supply, we yet cannot ignore the fact that many an insanitary area still exists which à priori might be expected to favour the spread of such disorders. We know, too, how great a scourge dysentery has been to armies in the field, where conditions of fatigue, exposure, imperfect diet, as well as defective sanitation, favour the development of intestinal disorders. My own limited experience confirms the fact of the rarity of dysentery in the general population. During the past thirty or forty years the average number of cases of dysentery admitted into the wards of the Middlesex Hospital has not exceeded one per annum, and in the seven years (1873–9) that I worked in the post-mortem room I only had to examine two subjects of dysentery, one of whom had contracted the disease in India. I was therefore much surprised to find, on joining the Lunacy Commission, that almost daily notifications were received from asylums of deaths from “colitis,” mostly ulcerative in character, and clinically indistinguishable from dysentery, as had been well shown by Dr. Gemmel just about that time. Dr. Gemmel's monograph, published in 1898, was founded on his personal observations at Lancaster Asylum, where for some years “idiopathic ulcerative colitis” had prevailed. It would, therefore, seem as if dysentery, whilst dying out from the population at large, had found a habitat in asylums, whose inmates, owing to their careful segregation, were less liable to most of the zymotic diseases. Regarded as an infective disease, which Dr. Gettings holds to be a sufficient explanation of its persistence in asylums, one can well understand the difficulty in getting rid of it once it has gained a footing, owing to the conditions of asylum life, and the faulty habits of many of the inmates. But it is only of late that it has been so regarded, for it has been customary to ascribe its occurrence to bad sanitation, of which, indeed, colitis was almost considered to be an index. Such a view seemed to be supported by instances like those mentioned by Dr. Gettings in the Wakefield Asylum, of outbreaks of dysentery coinciding with grave sanitary defects, the removal of which was followed by the subsidence of the disease. A classical instance is that of the outbreak at the Cumberland and Westmorland Asylum in 1864, reported on by Dr. (now Sir) Thomas Clouston, then its medical superintendent. The outbreak, which was a severe one, and accompanied with a high mortality, was connected with the irrigation of fields adjoining the asylum with untreated sewage. Col. Kenneth Macleod referred to this epidemic in a discussion at the Epidemiological Society in 1901, and said that when he himself was assistant medical officer at the Durham Asylum in 1864 there was a similar outbreak of dysentery also, and, as at Garlands, it was associated with sewage irrigation. These and similar instances all lent support to the opinion that dysentery resembled enteric fever in being a “filth disease,” meriting as much as the latter the appellation of “pythogenic,” which Murchison applied to typhoid.

AbstractF.W.J. Schelling’s Ages of the World has just begun to receive the critical attention it deserves as a contribution to the philosophy of history. Its most significant philosophical move is to pose the question of the origin of the past itself, asking what “caused” the past. Schelling treats the past not as a past present (something that used to be a ’now’ but no longer is) — but rather as an eternal past, a different dimension of time altogether, and one that was never a present ’now’. For Schelling, the past functions as the transcendental ground of the present, the true ’a priori’. Schelling’s account of the creation of this past takes the form of a theogeny: in order to exist, God needed to separate the past from the present. By grounding the creation of the past in a free decision of God, Schelling tries to conceptualize temporality so as to preserve the sort of radical contingency and authentic freedom that he considers essential features of history. In so doing, he opens up a way of viewing time that avoids the pitfalls of the Hegelian dialectic and anticipates some of the 20th century developments in phenomenology.

Interpolating a piecewise-linear triangulated surface between two polygons lying in parallel planes has attracted a lot of attention in the literature over the past three decades. This problem is the simplest variant of interpolation between parallel slices, which may contain multiple polygons with unrestricted geometries and/or topologies. Its solution has important applications to medical imaging, digitization of objects, geographical information systems, and more. Practically all currently-known methods for surface reconstruction from parallel slices assume a priori the existence of a non-self-intersecting triangulated surface defined over the vertices of the two polygons, which connects them. Gitlin et al. were the first to specify a nonmatable pair of polygons. In this paper we provide proof of the nonmatability of a “simpler” pair of polygons, which is less complex than the example given by Gitlin et al. Furthermore, we provide a family of polygon pairs with unbounded complexity, which we believe to be nonmatable. We also give a few sufficient conditions for polygon matability.

Michael Petry has observed that “until 1970 there was nobody among the hegelians, not to mention the philosophers of the Naturwissenschaften, willing to recognise Hegel's philosophy of nature as an area of investigation to be taken seriously.” An analogous fate seems to have afflicted Aristotle's Physics, if one agrees with Heidegger that: “The Aristotelian Physics is the arcane (verborgene) fundamental book of Western philosophy and, insofar as arcane, it has never been studied sufficiently.” Fortunately, the past neglect has been amply compensated for by the considerable degree of interest shown, in more recent years, towards both Hegel's and Aristotle's philosophy of nature. With reference to Hegel, that interest may have been nourished initially by the recognition of some isomorphic traits obtaining in Hegel's doctrine and in the methodology of structuralism and gestaltism. Furthermore, part of that interest must have also been triggered by the overall state of bankruptcy and disrepute which have befallen mechanistic, quantitative, empirical or neo-empirical and neo-positivist explanations of reality and of nature. Think of the developments of genetic biology, pathology and genetic engineering. Quantum Mechanics, the highly speculative turn in physics, cosmology, mathematics. By now, the assumptions, methods and findings of these sciences seem to be more kin to Aristotle and Hegel than to Newton and Galileo. Other hypothetical reasons could be offered, to explain the renewed attention paid to Hegel's philosophy of nature. One point, to begin with, emerges from the panorama of recent research on Hegel, namely that - regardless of and despite the recurrent mythical, hyper-animistic, anthropomorphic images, sustained by analogies and metaphorical diction; also despite of the frequent obscurities and downright factual mistakes - the philosopher cannot be sweepingly accused of scientific ignorance, nor of endemically gratuituous a priori, abstract reflection.
