The choroid plexuses (CPs) are involved in the most-basic aspects of neural function including maintaining the extracellular milieu of the brain by actively modulating chemical exchange between the CSF and brain parenchyma, surveying the chemical and immunological status of the brain, detoxifying the brain, secreting a nutritive “cocktail” of polypeptides and participating in repair processes following trauma. This diversity of functions may mean that even modest changes in the CP can have far-reaching effects. Indeed, changes in the anatomy and physiology (...) of the CP have been linked to aging and several CNS diseases. It is also possible that replacing diseased or transplanting healthy CP might be useful for treating acute and chronic brain diseases. This review focuses on the wide-ranging and under-appreciated functions of the CP, alterations of these functions in aging and neurodegeneration, and recent demonstrations of the therapeutic potential of transplanted CP for neural trauma.

We present integral equations for the scattering amplitudes of three scalar particles, using the Faddeev channel decomposition, which can be readily extended to any finite number of particles of any helicity. The solution of these equations, which have been demonstrated to be calculable, provide a nonperturbative way of obtaining relativistic scattering amplitudes for any finite number of particles that are Lorentz invariant, unitary, cluster decomposable and reduce unambiguously in the nonrelativistic limit to the nonrelativistic Faddeev equations. The aim of this (...) program is to develop equations which explicitly depend upon physically observable input variables, and do not require “renormalization” or “dressing” of these parameters to connect them to the boundary states. As a unitary, cluster decomposible, multichannel theory, physical systems whose constituents are confined can be readily described. (shrink)

The Structures of the Life-World is the final focus of twenty-seven years of Alfred Schutz's labor, encompassing the fruits of his work between 1932 and his death in 1959. This book represents Schutz's seminal attempt to achieve a comprehensive grasp of the nature of social reality. Here he integrates his theory of relevance with his analysis of social structures. Thomas Luckmann, a former student of Schutz's, completed the manuscript for publication after Schutz's untimely death.

Translation and Introduction by Fred Kersten Alfred Schutz’s lecture, “The Problem of Intersubjectivity in Husserl,” was read and discussed at the Husserl-Colloquium in Royaumont on April 28, 1957. The German text of the lecture appeared in Philosophische Rundschau: Eine Vierteljahrsschrift für philosophische Kritik, edited by Hans-Georg Gadamer and Helmut Kuhn, Vol. V, 1957, pp. 81ff. A translation of the lecture by Frederick Kersten in collaboration with Professors Aron Gurwitsch and Professor Thomas Luckmann was published in Alfred Schutz, Collected (...) Papers, Volume III, edited by Ilse Schutz and an Introduction by Aron Gurwitsch. (shrink)

I start, in Section I, with the case for skepticism about the possibility of self-deception. In Sections II and III, I review attempts to explain how self-deception, conceived on a strict interpersonal model, is possible. Section IV addresses a variety of analyses of self-deception that involve modest departures from these strict models and canvasses associated attacks on the standard paradoxes. The emphasis there is on the static paradoxes, discussion of their dynamic coun terparts being reserved largely for Section V. Section (...) VI takes up Herbert Fingarette's apparently radical departure from the interpersonal models of deception, while Section VII distinguishes among three approaches to the philosophical investigation of self-deception. I conclude, in Section VIII, with a comment on a promising direction for future work on the topic. (shrink)

Long debated has been whether or not the “objectivistic” epistemologies, quantitative methods and causal explanations, developed by the natural sciences for the study of physical objects, their actions and interactions, might also be applied to the study of human subjects, their experiences, actions and social interactions. Pointing out that such supposedly objective approaches would be singularly inappropriate to the study of the significance or meanings, qualitative values and freedom of choice, widely regarded as essential aspects of human subjects, their experiences, (...) actions, and social interactions, and drawing attention, a la Alfred Schutz, to the two meanings of the term “subjective” it is first argued that many of the claims of the natural sciences themselves are “empirically” unverifiable, in the Positivistic sense of that term. Moreover, and most crucially, it is further argued that the “objectivity” of an experience cannot be empirically established on the basis of its supposed correspondence to some “objective” world—for, as precisely appearance or experience transcending, the existence of such a world, much less its nature, is clearly empirically unverifiable—and must therefore rest upon inter-subjective coherence, which in turn must, as Schutz has pointed out, depend precisely upon the very subjective experiences which those who would council such an “objective” approach, had ipso facto, sought to avoid as unverifiable. Thus, paradoxically, the criterion of objective verification cannot itself be objectively verified, but rests upon appeals to “subjective” experiences. (shrink)

In early 1864, disappointed by the response to his previous work, the young Manchester academic W. Stanley Jevons announced that he was undertaking a study of the so-called coal question: ‘A good publication on the subject would draw a good deal of attention … it is necessary for the present at any rate to write on popular subjects’. When Jevons's The Coal Question was published in April 1865, however, it received comparatively little attention and sales were slow. Jevons and his (...) publisher, Alexander Macmillan, then began sending complimentary copies to luminaries such as Sir John Herschel and Alfred Tennyson. In February 1866 the marketing campaign produced its first substantial return. Macmillan had sent CQ to William Gladstone who responded with letters to both Macmillan and Jevons, noting that the book had strengthened his ‘conviction’ on the necessity for reducing the National Debt. In April, John Stuart Mill praised CQ in the House of Commons, calling for action on the Debt and, three weeks later, as Chancellor of the Exchequer, Gladstone introduced the budget using half his speech to examine the Debt situation and referring to CQ in support for a proposed measure of Debt reduction. With the extensive publicity given to CQ following Mill's speech and the budget, Jevons had achieved his objective in writing the text which went into a second edition in 1866. On the face of it, CQ 's success was due to its effect of introducing a change in budget policy and this is the impression given by some accounts of the episode. (shrink)

The book (in German) on “Solar Energy – challenge for research, development and international co-operation” is the report of a study group of the Akademie der Wissenschaften zu Berlin. It reviews solar thermal, photovoltaic, and bio mimetic solar energy techniques; prospects of de-central techniques in developing countries; transport and storage of solar energy; and chances for cooperation with Arabic countries and countries of the South of the former Soviet Union. The prospect of large scale energy production in arid areas, and (...) the modern potentials of conducting electricity over long distances by high-voltage DC transmission (V, 2.1) are particularly relevant for the concluding section. Political chances as well as risks were considered for reliable long term cooperation with various Arab countries on these issues. The recommendations appear to be still appropriate 25 years after the book was published, particularly the political advice in favour of cooperation between Europe and suitable countries of the Maghreb. The global time scale of implementation (discussed in chapter I, 7.2) is of the same (high) magnitude as that of other major changes in the history of technology, such as the substitution of sailing ships by steamboats which took almost a century.
