This paper presents a platform for developing, testing and executing synchronous collaborative applications in a distributed, heterogeneous environment. Even though several environments exist nowadays, specific problems are not treated satisfactorily. Especially in ‘real’ network environments, problems like unstable network connections and low bandwidths have to be considered.The DreamTeam platform addresses the special needs of environments with non-optimal characteristics which can, be found in distance learning scenarios. DreamTeam comprises a development environment, a simulation environment and a runtime environment; it is based (...) upon the concept of a fully decentralised architecture and encourages rapid prototyping.DreamTeam supports developers of shared applications through a component concept. Using components helps to divide a software project into well-defined parts. Well-documented interfaces help to reduce integration efforts and improve software quality. A selection of sample applications with DreamTeam validates our design concept. (shrink)

Whereas the Upanishads contain much which is, strictly speaking, of little interest to the historian of Indian thought, the Pre-Upanishadic texts are not completely devoid of passages which are of special importance for anyone who endeavours to trace the origin and oldest form of the main texts of classical Indian philosophy. Too often the difference between Upanishads and Pre-Upanishadic literature has been exaggerated ; too often the philosophical importance of the ritualistic speculations contained in the Brahmanas has been undervalued ; (...) too often these texts have been neglected by the compilers of handbooks. One of those points which have not always received due attention concerns the theoretic foundation of the belief in the possibility of gaining the victory over death and of the efforts to realize this ambition. One of the most important problems in which the Indians have always been interested is the relation between the One and the Many, between this phenomenal world and its source and ground. Already in the Rgveda opinions differ : it has been a divine architect who made the phenomenal world ; it has been an anonymous primeval deity who became a golden germ from which a demiurge was born ; the world has arisen from the impersonal One who desired to create the world, etc. In the course of time these creators and ideas of the original One fused into the great figure of Prajapati, „the Lord of Creatures”. This God, who occupies a central position in the Brdhmawa-texts originally was what he was to remain in popular belief : the deity presiding over biological creation. In the ritualistic speculations of the authors of the Brahmanas he is the Creator, the Father of gods and anti-gods, the origin of creation. In the beginning Prajapati was alone, he was ,all this’, he was the universe in ,concentrated’ and unmanifested form. By way of emanation and self-differentiation he became the manifested universe, including the creatures. After this creative activity he is empty and exhausted, because he has ,entered the universe' or rather transformed himself into the universe. His strength, force and health can however be recovered and restored by means of rites. The world and the creatures which emanated from Prajapati were not perfect ; they were a discontinuum, disintegrated, in the power of death. In order to make life possible and to make the world habitable Prajdpati instituted rites. Prajapati is in the Brahmanas identified with the highest and most general categories ; he is the year, i.e. the complete cycle of time comprising the past and the future, totality and completeness. The year, viewed as an integral structure is the fundamental basis of all that happens. Being also the rite, the sacral act, Prajapati is on the other hand the earthly counterpart of the great cosmic drama. On these two identifications the ritualistic system of these authors is constructed. Among these authorities Sandilya. occupies a prominent place. The mundane events oscillating between the poles of birth and death, of genesis and decay, rites are needed to reintegrate what has become decomposed. They are however also to restore the original unity and totality, to co-ordinate the non-co-ordinated phenomena, to reconstruct Prajapati, to restore his original oneness. The rites reduce, temporarily it is true and with regard to the individual who has them performed, the phenomenal multiplicity to a reintegrated totality, in which the diversity of Prajapati's emanation has been destroyed, and the original unity and oneness has been restored. This theory underlies the structure of the great Fire-altar , by which the sacrificer identifies himself with Prajapati whose original unity is restored. By performing this elaborate ritual the personality of the sacrificer was transformed into a new and divine existence, which was no longer subject to the imperfections proper to this world. That is to say : the sacrificer acquires ,immortality' , he transcends the limits of phenomenal time, he becomes sarva, i.e. safe-andsound, whole. Prajapati-the year will not destroy the man who identifies himself with the totality, with Prajapati-the year, and who has acquired an insight into the meaning of this identification ; that man overcomes disintegration and discontinuity, he gains the victory over death, that is to say : he attains to a sound and complete condition. In the course of time the personal Prajapati and the impersonal Brahman are identified. In the early Upanishads the latter becomes the great fundamental principle. These works resume on the one hand ancient speculations a part of which has been preserved in the Rg- and Atharvavedas, and utilize, on the other hand, the ritualistic theories of the Brdhmawas. The tendency of their authors is however to dissociate themselves from ritualism. Emphasizing the quest for the salvation and spiritual welfare of the individual they go into the problem of the ,Soul' , that is the ,self' or the very core of the personality, which is essentially different from all phenomenal plurality. The hitman is identified with the Punira, the primeval man out of whom the universe arose. It follows that the Atrmn is also cosmic. According to Udddlaka Arum it is the subtle essence of all that exists. All the important potencies in the universe are said to be its manifestations. However, in these works . Htman and Brahman tend to fuse and the great teacher Ydjwavalkya concluded to their being identical. Ordinary men do not understand this identity, but the few who are able to arrive at this highly important insight gain the victory over the imperfections and contingencies of empirical existence. They experience the ecstatic and unanalysable condition of unity, the undifferentiated Plenum or Totality, the ,All'. They know that they are truly Brahman or Sarvam. Now, it is most important to attain to this condition, which implies the victory over death, before one is to die the worldly death. The man who dies without having escaped death will die again and again in the hereafter. Whereas the ritualists attempt to protect themselves from this much feared ,repeated death' by means of rites, especially by the construction of the Fire-altar, the teachers whose words are recorded in the early Upanishads ascribed the delivering power to the esoteric knowledge of the ,under lying theory', to the knowledge of the ritual-cosmic interrelations : the man who knows the relevant speculations will be released. This belief in the redeeming power of the rites and the ,theory' on which they are based was also of special importance with regard to the development of the Karman-doctrine. Thus ritual and spiritual identification with the One which is the Totality, the Primeval Being, the Creator, the Atman enables man by experiencing a transformation to conquer phenomenal time and death.

Geothermal energy accounts for 43% of the electricity expenditure of São Miguel Island, Azores Archipelago. All production comes from the Ribeira Grande high-enthalpy geothermal field. To meet the growing energy demand in the island, it is necessary to extend the exploration efforts to new areas. We evaluated the results of a broadband magnetotelluric reconnaissance survey conducted at Sete Cidades Volcano, placed only 30 km westward of the RG field. The resistivity structure of the Sete Cidades geothermal system was obtained through (...) a simultaneous 3D inversion of the full impedance tensor and tipper. The bathymetry and the topography of the island were treated as fixed features in the model. The geothermal reservoir at Sete Cidades is outlined as a northwest–southeast elongated resistive anomaly, geologically controlled by the Terceira Rift fracture zone. We have also identified high-conductivity zones between 1000 and 4000 m below mean sea level, probably associated with clay cap rocks overlying the geothermal reservoir. (shrink)

A brief preface to the Cambridge Companion to Nietzsche announces the aims of the ambitious series of which this volume is a part: to provide students and nonspecialists with a handy reference volume and to help them overcome the “intimidation” they often feel when encountering a difficult thinker for the first time. Unlike the other volumes that I have seen in the Companion series, this one truly is pitched to the undergraduate and/or popular market. Of the 11 articles, only 4 (...) are grouped under the rubric “Nietzsche as Philosopher,” although Tracy B. Strong’s essay, “Nietzsche’s Political Misappropriation,” and Jörg Salaquarda’s “Nietzsche and the Judeo-Christian Tradition”—both listed under part II, “The Use and Abuse of Nietzsche’s Life and Works”—in their analysis of Nietzsche’s politics and his critique of religion certainly strike philosophical, or at least theoretical, poses. So, we have 6 articles out of eleven, roughly 191 out of 403 pages, that are devoted to the analysis, or at least discussion, of Nietzsche’s philosophy as such. The remaining articles treat broadly biographical topics and Nietzsche’s reception: in the 20th Century in general, in France, and in East Asia. This proportion, sadly, echoes the larger structure of the Nietzsche legend, which often expresses a desire to explain Nietzsche’s philosophy by means of certain biographical details, and which is in fact the central topic of R.J. Hollingdale’s contribution to this volume, “The Hero as Outsider.” That the devotion of such a disproportionate amount of space to what are arguably tangential issues is not inevitable is proven by the splendid Cambridge Companion to Spinoza, edited by Don Garrett, in which one article each is devoted to Spinoza’s life and his reception, with the remaining eight articles organized according to major topics in Spinoza’s philosophy: metaphysics, philosophy of mind, politics, critique of religion, et cetera, thus giving us a proper 8/2 proportion in favor of philosophy—and this vis-à-vis a philosopher with his own “extra-philosophical” legend. Of course, the Nietzsche question is complicated by National Socialism, among other things. (shrink)

We study the problem of existence and generic existence of ultrafilters on ω. We prove a conjecture of $J\ddot{o}rg$ Brendle's showing that there is an ultrafilter that is countably closed but is not an ordinal ultrafilter under CH. We also show that Canjar's previous partial characterization of the generic existence of Q-points is the best that can be done. More simply put, there is no normal cardinal invariant equality that fully characterizes the generic existence of Q-points. We then sharpen results (...) on generic existence with the introduction of $\sigma-compact$ ultrafilters. We show that the generic existence of said ultrafilters is equivalent to $\delta = c$ . This result taken along with our result that there exists a $K_{\sigma}$ non-countably closed ultrafilter under CH, expands the size of the class of ultrafilters that were known to fit this description before. From the core of the proof, we get a new result on the cardinal invariants of the continuum, i.e., the cofinality of the sets with $\sigma-compact$ closure is δ. (shrink)

There are many alternative ways that a mind or brain might represent that two of its representations were of the same object or property, the 'Strawson' model, the 'duplicates' model, the 'synchrony' mode, the 'Christmas lights' model, the 'anaphor' model, and so forth. I first discuss what would constitute that a mind or brain was using one of these systems of identity marking rather than another. I then discuss devastating effects that adopting the Strawson model has on the notion that (...) there are such things as modes of presentation in thought. Next I argue that Evans' idea that there are 'dynamic Fregean thoughts' has exactly the same implications. I argue further that all of the other models of thought discussed earlier are in fact isomorphic to the Strawson model. a search for the source of these difficulties reveals the classical notion of modes of presentation as resting on two assumptions, neither of which I recommend. It depends on denying that the way the mind reacts to or understands the thoughts or ideas that it harbours has any bearing on their intentional contents. And it depends on an internalist view of thought content, in particular, on denying that the natural informational content carried or potentially carried by a thought has any bearing on its intentional content.

It is a pleasure for me to give this opening address to the Royal Institute of Philosophy Conference on ‘Explanation’ for two reasons. The first is that it is succeeded by exciting symposia and other papers concerned with various special aspects of the topic of explanation. The second is that the conference is being held in my old alma mater , the University of Glasgow, where I did my first degree. Especially due to C. A. Campbell and George Brown there (...) was in the Logic Department a big emphasis on absolute idealism, especially F. H. Bradley. My inclinations were to oppose this line of thought and to espouse the empiricism and realism of Russell, Broad and the like. Empiricism was represented in the department by D. R. Cousin, a modest man who published relatively little, but who was of quite extraordinary philosophical acumen and lucidity, and by Miss M. J. Levett, whose translation of Plato's Theaetetus formed an important part of the philosophy syllabus. (shrink)

J.S. Mill's plural voting proposal in Considerations on Representative Government presents political theorists with a puzzle: the elitist proposal that some individuals deserve a greater voice than others seems at odds with Mill's repeated arguments for the value of full participation in government. This essay looks at Mill's arguments for plural voting, arguing that, far from being motivated solely by elitism, Mill's account is actually driven by a commitment to both competence and participation. It goes on to argue that, for (...) Mill, much of the value of political participation lies in its unique ability to educate the participants. That ability to educate is not, however, a product of participation alone; rather, for Mill, the true educative benefits of participation obtain only when competence and participation work together in the political sphere. Plural voting, then, is a mechanism for allowing Mill to take advantage of the educative benefits that arise from the intersection of competence and participation. (shrink)

In its broadest sense, "universality" is a technical term for something quite ordinary. It refers to the existence of patterns of behavior by physical systems that recur and repeat despite the fact that in some sense the situations in which these patterns recur and repeat are different. Rainbows, for example, always exhibit the same pattern of spacings and intensities of their bows despite the fact that the rain showers are different on each occasion. They are different because the shapes of (...) the drops, and their sizes can vary quite widely due to differences in temperature, wind direction, etc. There are different questions one might ask about such patterns. For instance, one might ask why the particular rainbow... (shrink)

Human conflict and its resolution is obviously a subject of great practical importance. Equally obviously, it is a vast subject, ranging from total war at one end of the spectrum to negotiated settlement at its other end. The literature on the subject is correspondingly vast and, in recent times, technical, thanks to the valuable contributions made to it by game theorists, economists, and writers on industrial and international relations. In this essay, however, I shall discuss only one familiar form of (...) conflict-resolution. There is room for such a discussion, because philosophers have lately neglected compromise, despite the interest shown in it by the aforementioned experts, and despite the classic treatments of it by Halifax, Burke and Morley. Truly, ‘…compromise is not so widely discussed by philosophers as one might expect’, and ‘…the idea of compromise has been largely neglected by Anglo-American jurisprudence’. (shrink)
