There is no evidence to suggest that even as late as January 1672, when Newton was elected a Fellow of the Royal Society, anyone had any inkling of his new theory of colours. His name exploded on the scientific scene as the inventor and constructor of a new kind of telescope—what later became known as the reflector . Had the erudition of the London virtuosi been a little broader, they would have known that in fact he was not the inventor (...) of the telescope, even though the precise form he gave it was his. Not only was the idea a hundred years old, during which period it was repeatedly suggested by various writers, but also Newton himself took the idea straight from the most recent of these suggestions, namely that included in James Gregory's Optica promota of 1663. The situation becomes even more ironic when we realize that the new instrument was admired for wrong reasons and on merits that were far from Newton's intentions. Nevertheless, admired it was, and there was a good reason for this: Newton's instrument was in fact the first reflector actually to be constructed and, moreover, for a few weeks it performed quite well. Several astonomers became interested because of the high magnifying power relative to its dimensions. (shrink)

This article discusses the different meanings of ‘keyword’ and related terms such as ‘keyphrase', ‘descriptor’, ‘index term’, ‘subject heading’, ‘tag’ and ‘n-gram’ and suggests definitions of each of these terms. It further illustrates a classification of keywords, based on how they are produced or who is the actor generating them and present comparison between author-assigned keywords, indexer-assigned keywords and reader-assigned keywords as well as the automatic generation of keywords. The article also considers the functions of keywords including the use of (...) keywords for generating bibliographic indexes. The theoretical view informing the article is that the assignment of a keyword to a text, picture or other document involves an interpretation of the document and an evaluation of the document’s potentials for users. This perspective is important for both manually assigned keywords and for automated generation and is opposed to a strong tendency to consider a set of keywords as ideally presenting one best representation of a document for all requests.

A table of contents is a kind of document representation as well as a paratext and a kind of finding device to the document it represents. TOCs are very common in books and some other kinds of documents, but not in all kinds. This article discusses the definition and functions of ToC, normative guidelines for their design, and the history and forms of ToC in different kinds of documents and media. A main part of the article is about the role (...) of ToC in information searching, in current awareness services and as items added to bibliographical records. The introduction and the conclusion focus on the core theoretical issues concerning ToCs. Should they be document-oriented or request-oriented, neutral, or policy-oriented, objective, or subjective? It is concluded that because of the special functions of ToCs, the arguments for the request-oriented view are weaker than they are in relation to indexing and knowledge organization in general. Apart from level of granularity, the evaluation of a ToC is difficult to separate from the evaluation of the structuring and naming of the elements of the structure of the document it represents.

The secrets from the inner meaning of Torah form the soul of the Chasidic movement's thought. They inspire, revive, and inflame Jewish souls with a passion to constantly increase observance and devotion. For more than two centuries it has inoculated millions against the ravages of secularism and preserved the spiritual life of the Jewish nation. Chasidus emerged as a protection from the storm winds of modernity. Today's Jewish community might benefit from a new look at the Chasidic movement's beginnings and (...) reflections. Even those Jews who fulfill their religious obligations frequently perform rituals in a lifeless and superficial way. Were we to discover the depth and soulful vitality that fill Chasidic literature, a renewed passion might flame our faltering Jewish experience with the warmth of Torah. Unfortunately, for many of my contemporary American Jews, access to the gem-stones of the Chasidim has been denied. Chasidic works are overwhelmingly in Hebrew, and few good translations exist. This book provides an introduction to the basic terms and ideas of Chasidic texts. It is written for the interested lay reader who may be new to Torah study, as well as the yeshiva student who is knowledgeable about Biblical narratives and Talmudic law but may be new to the world of Chasidus.

The ideas of cultural-historical psychology have led to a new understanding of the human psyche as developing in the process of the subject acting in social and historical contexts. Such a “non-classical” reinterpretation of psychological concepts should be based on a theoretical and philosophical framework in order to explain genetic sources of these concepts. For this purpose, Il’enkov’s philosophy is of great significance. This is illustrated by discussing a possible cultural-historical understanding of the concept of intelligence.

In lieu of an abstract, here is a brief excerpt of the content:Good Neighbors Make Good Fences: Frost’s “Mending Wall”Zev TrachtenbergDefenders of the institution of private property have considered at length its benefits to individuals: for Aristotle it allows for the practice of certain virtues; for Hegel it allows for the expression of free human personality. 1 Property is also, of course, seen as the foundation of political society: for Locke men form government to enforce their property rights; for Jefferson (...) property enables citizens to participate in their institutions of self-government. 2But there is a level of human experience between simple individuality and the formal rules and rights articulated and enforced by society. I have in mind the more immediate form of human association evoked by the word community. Let me offer a rough-and-ready distinction. The social contract tradition prompts us to think of society in terms of the cooperative human enterprise of protecting individuals’ interests; the concept of society calls to mind formal voluntary agreements and associations, contracts, the economy, ultimately laws and rights. 3 We can think of community, by contrast, in affective terms; it calls to mind the direct human relations of people who share a place and mode of living. 4 A society has laws and a government; a community has customs and a culture.In this essay, then, I want to explore the relationship between property and community. It is, I think, an ambiguous one: property can be accused of corroding the human connections that constitute community life, but the maintenance of a property regime can also be seen as itself a communal enterprise. 5 This ambiguity is displayed vividly in Robert Frost’s “Mending Wall.” 6 Reading the poem can help us see the complex ways in which property and community are intertwined. [End Page 114]I“Mending Wall” has two characters: its narrator and his neighbor, owners of adjacent farms, who meet each Spring to repair the stone wall that stands between their properties. The narrator, at first glance, seems to take a somewhat skeptical attitude toward property. (We shall see that his attitude is in fact more complicated.) The poem opens with his words “Something there is that doesn’t love a wall”—a phrase he repeats later, making it a kind of slogan for the position on property he personifies. That position seems to reject human attempts to inscribe the arbitrary divisions of property holdings on the land. The narrator sees in natural processes an attempt to cast off this artificial imposition: that which doesn’t love a wall “sends the frozen-ground-swell under it, /And spills the upper boulders in the sun.” He recognizes that asserting a separation between the two parcels of property by erecting a wall is futile. For, he recognizes, the two parcels are one, connected underneath the wall by natural forces that work unconsciously but actively against human efforts to divide them.The neighbor, by contrast, speaks for an individualistic belief in the value of marking property holdings. “Good fences make good neighbors” are his only words in the poem, repeated in the last line like a counter-slogan to the narrator’s. The neighbor first offers his slogan in response to the fact that the wall is not needed for the practical purpose of keeping his and the narrator’s goods separate. Their goods do not need a wall to be kept apart: they have no cows to wander back and forth across the line, and the narrator’s “apple trees will never get across/And eat the cones under [the neighbor’s] pines.” For the neighbor, that is, the utility of the wall is not economic. Rather it serves to define the sort of relationship he wishes to have with those who surround him: his slogan expresses an ideology of human separation. In the neighbor’s eyes, apparently, all that makes a neighbor is the mere fact of owning an adjacent farm, hence what makes a good neighbor is his separateness. For what else could characterize the goodness of neighbors who are made good by fences?The neighbor thus personifies a position on property that disvalues community. Property is marked by walls, whose main function in his view... (shrink)

The ArgumentThe inclusion of an item within a theory may be essential or accidental, and if the former then the explanation of its meaning and of its inclusion in the theory cannot be by accidental events and circumstances. Since all events and circumstances – be they social, political, religious, psychological, etc. – are accidental vis-à-vis the ideas they occasion, they cannot serve as explanation of these ideas. The only way to explain the ideas is by showing their essentiality to the (...) theory rather than their importance to the people. Thus, the place of spirits and souls within seventeenth-century science is explained by Platonic ideology.This demands a concept of nature which is thoroughly efficient causative, and a concept of explanation which is thoroughly informative. This means that theories must explain any given effect by a cause which is separable from it and is conceptually heterogeneous to it. Such a nature and such an explanation are inherently paradoxical and irrational, which explains the preponderance of these traits in seventeenth-century science as created by Kepler, through Galileo and Descartes to Newton.The primary efficient-causal and explanatory agency is force, which is ontically distinct from matter and from the motion it causes in matter. Soul, spirit and active principle are mere variants of force. Thus, their presence in seventeenth-century science is explained only by their being conceptually essential to any Platonic philosophy of nature. (shrink)

Hospital systems commonly face the challenge of determining just ways to allocate scarce drugs during national shortages. There is no standardised approach of how this should be instituted, but principles of distributive justice are commonly used so that patients who are most likely to benefit from the drug receive it. As a result, clinical indications, in which the evidence for the drug is assumed to be established, are often prioritised over research use. In this manuscript, we present a case of (...) a phase II investigational trial of intravenous thiamine for delirium prevention in patients undergoing haematopoietic stem cell transplantation to emphasise several shortcomings in the overarching prioritisation of clinical over research uses of scarce drugs. Specifically, we present the following considerations: clinical use may not have stronger evidence than research use; a strong scientific rationale for research use may outweigh the claim for clinical indications in which there is weak evidence; treatment within the context of a clinical trial may be the standard of care; and research use may not only benefit patients receiving the treatment but also offers the prospect of improving future clinical care. In summary, we argue against allocation schemes that prohibit all research uses of scarce drugs and instead recommend that allocation schemes include a balanced approach that weighs risks and benefits of access to scarce drugs irrespective of the research versus clinical use designation.

We describe sets of partial Boolean functions being closed under the operations of superposition. For any class A of total functions we define the set ????(A) consisting of all partial classes which contain precisely the functions of A as total functions. The cardinalities of such sets ????(A) can be finite or infinite. We state some general results on ????(A). In particular, we describe all 30 closed sets of partial Boolean functions which contain all monotone and zero-preserving total Boolean functions.

By analysing Rousseau's conception of the general will, Zev Trachtenberg characterises the attitude of civic virtue Rousseau believes individuals must have to cooperate successfully in society. Rousseau holds that culture affects political life by either fostering or discouraging civic virtue. However, while the cultural institutions Rousseau endorses would motivate citizens to obey the law, they would not prepare citizens to help frame it. Rousseau's view of culture thus works against his account of legitimacy, and Trachtenberg concludes that Rousseau's political theory (...) as a whole is inconsistent. (shrink)

This is a critical and exegetical introduction to the work and thought of Hannah Arendt, one of the most powerful and important political thinkers of the twentieth century. The book traces the connections in Arendt's work between public life and political thinking and the ways in which each informs the other. In conclusion, the author suggests why Arendt provides a unique way of rendering the political visible and relevant to people in an everyday setting.
