Twelve-year-old Kalman Gabriel wrote to hundreds of famous -- and infamous -- people to find out what kind of advice for life they would impart upon him. The response was overwhelming. Over two hundred people, from Mother Teresa to Mr. Rogers: from Ray Bradbury and Scott Turow to Naomi Judd and Drew Barrymore, responded to Kalman's letters. Leona Helmsley told Kalman, "Presevere," while Elie Weisel advised, "Study. Read. Share." Kalman's files are compulsively readable and infinitely quotable.

Conventional wisdom holds that Judaism is indifferent or even suspiciously hostile to the visual arts due to the Second Commandment's prohibition on creating "graven images," the dictates of monotheism, and historical happenstance. This intellectual history of medieval and modern Jewish attitudes toward art and representation overturns the modern assumption of Jewish iconophobia that denies to Jewish culture a visual dimension. Kalman Bland synthesizes evidence from medieval Jewish philosophy, mysticism, poetry, biblical commentaries, travelogues, and law, concluding that premodern Jewish intellectuals held (...) a positive, liberal understanding of the Second Commandment and did, in fact, articulate a certain Jewish aesthetic. He draws on this insight to consider modern ideas of Jewish art, revealing how they are inextricably linked to diverse notions about modern Jewish identity that are themselves entwined with arguments over Zionism, integration, and anti-Semitism. Through its use of the past to illuminate the present and its analysis of how the present informs our readings of the past, this book establishes a new assessment of Jewish aesthetic theory rooted in historical analysis. Authoritative and original in its identification of authentic Jewish traditions of painting, sculpture, and architecture, this volume will ripple the waters of several disciplines, including Jewish studies, art history, medieval and modern history, and philosophy.

Buber proclaims that 'in the beginning was relation'; that man is by his very nature a Homo Dialogus - incapable of realizing himself without communion with man, with the creation and with his Creator.Buber sought to anchor Zionism in what he defined as 'Hebrew Humanism': "the path of holiness" as opposed to "holy egoism".

Interest in the intersection between bilingualism and cognitive control and accessibility to neuroimaging methods have resulted in numerous studies with a variety of interpretations of the bilingual cognitive advantage. Neurocomputational Emergentism (or Neuroemergentism for short) is a new framework for understanding this relationship between bilingualism and cognitive control. This framework considers Emergence, in which two small elements are recombined in an interactive manner, yielding a non-linear effect. Added to this is the notion that Emergence can be captured in neural systems (...) using computationally inspired models. This review poses that bilingualism and cognitive control, as examined through the Neuroemergentist framework, are interwoven through development and involve the non-linear growth of cognitive processing encompassing brain areas that combine and recombine, in symbiotic and parasitic ways, in order to handle more complex types of processing. The models that have sought to explain the neural substrates of bilingual cognitive differences will be discussed with a reinterpretation of the entire bilingual cognitive advantage within a Neuroemergentist framework incorporating its neural bases. It will conclude by discussing how this new Neuroemergentist approach alters our view of the effects of language experience on cognitive control. Avenues to move beyond the simple notion of a bilingual advantage or lack thereof will be proposed. (shrink)

The Origin of the ‘Paardekraal Vow’ Contrary to common belief that the ‘1880 Vow' was taken at Paardekraal, on the restoration of the Republic on 13 December 1880, the writer has documentary proof that this ‘Vow’ was in existence almost two years before that date. An agreement is said to have been signed by a number of the Boers at Wonderfontein, where they had gathered between 10 and 13 January 1879 to claim the restoration of the Republic. Both these minutes (...) and the Transvaal press ignored this agreement as it was feared that they would lead to premature armed resistance. The Paardekraal Festival Commission became aware of the agreement in 1945 and adopted it as the ‘Vow of 1880' in their 1946 programme. (shrink)

Condensed detachment is usually regarded as a notation, and defined by example. In this paper it is regarded as a rule of inference, and rigorously defined with the help of the Unification Theorem of J. A. Robinson. Historically, however, the invention of condensed detachment by C. A. Meredith preceded Robinson's studies of unification. It is argued that Meredith's ideas deserve recognition in the history of unification, and the possibility that Meredith was influenced, through ukasiewicz, by ideas of Tarski going back (...) at least to 1939, and possibly to 1930 or earlier, is discussed. It is proved that a term is derivable by substitution and ordinary detachment from given axioms if and only if it is a substitution instance of a term which is derivable from these axioms by condensed detachment, and it is shown how this theorem enables the ideas of ukasiewicz and Tarski mentioned above to be formalized and extended. Finally, it is shown how condensed detachment may be subsumed within the resolution principle of J. A. Robinson, and several computer studies of particular Hilbert-type propositional calculi using programs based on condensed detachment or on resolution are briefly discussed. (shrink)

A recurrent theme in contemporary narratives of grieving is that there is a gap between the griever’s more or less consciously chosen expression of, and acting out of, grief and loss and other people’s seeming lack of acceptance. Starting from the view that the social context of feelings and emotions are constitutive in making an emotional experience what it is, this article explores what is done and experienced in acts of grief. A phenomenological perspective is applied to analyze the conditioning (...) of these experiences, and what the acts of grieving may accomplish in relation to various aspects of the self, indeed selves—that is, in relation to the surviving relative as well as the deceased.

Historians have recently used the Internet to circulate political statements about law. This paper explores the statements they issued against President Clinton's impeachment and President Bush's inauguration. It pays special attention to impeachment, comparing the position taken by historians with that taken by the law professors. While concluding that such statements can be useful, the author advises historians lacking the expertise to evaluate the positions taken in a statement to proceed carefully in signing it. She suggests that historians sign only (...) such documents whose scholarship they have made a preliminary assessment that they could individually defend publicly. She also urges historians to craft statements that give the public a sense of the methods they use in interpreting the past. (shrink)

In the first part of this paper we indicate how Meredith's condensed detachment may be used to give a new proof of Belnap's theorem that if every axiom x of a calculus S has the two-property that every variable which occurs in x occurs exactly twice in x, then every theorem of S is a substitution instance of a theorem of S which has the two-property. In the remainder of the paper we discuss the use of mechanical theorem-provers, based either (...) on condensed detachment or on the resolution rule of J. A. Robinson, to investigate various calculi whose axioms all have the two-property. Particular attention is given to D-groupoids, i.e. sets of formulae which are closed under condensed detachment.

The paper sets out to offer an alternative to the function/argument approach to the most essential aspects of natural language meanings. That is, we question the assumption that semantic completeness (of, e.g., propositions) or incompleteness (of, e.g., predicates) exactly replicate the corresponding grammatical concepts (of, e.g., sentences and verbs, respectively). We argue that even if one gives up this assumption, it is still possible to keep the compositionality of the semantic interpretation of simple predicate/argument structures. In our opinion, compositionality presupposes (...) that we are able to compare arbitrary meanings in term of information content. This is why our proposal relies on an ‘intrinsically’ type free algebraic semantic theory. The basic entities in our models are neither individuals, nor eventualities, nor their properties, but ‘pieces of evidence’ for believing in the ‘truth’ or ‘existence’ or ‘identity’ of any kind of phenomenon. Our formal language contains a single binary non-associative constructor used for creating structured complex terms representing arbitrary phenomena. We give a finite Hilbert-style axiomatisation and a decision algorithm for the entailment problem of the suggested system. (shrink)

Network ranging and clock synchronization based on two-way timing stamps exchange mechanism in complex GPS-denied environments is addressed in this paper. An estimator based on the Extended Kalman filter is derived, according to which, the clock skew, clock offset, and ranging information can be jointly estimated. The proposed estimator provides off-line computation by storing the transmitting timing stamps in advance and could be implemented in asymmetrical and asynchronous scenarios. The simulation results show that the proposed estimator achieves a relative good (...) performance than the existed estimators. In addition, a new Bayesian Cramér–Rao Lower Bound is derived. Numerous simulation results show that the proposed estimator meets the B-CRLB. (shrink)

The strap-down inertial navigation system is a commonly used sensor for autonomous underground navigation, which can be used for shearer positioning under a coal mine. During the process of initial alignment, inaccurate or time-varying noise covariance matrices will significantly degrade the accuracy of the initial alignment of the shearer. To overcome the performance degradation of the existing initial alignment algorithm under complex underground environment, a novel adaptive filtering algorithm is proposed by the integration of the strong tracking Kalman filter and (...) the sequential filter for the initial alignment of the shearer with complex underground environment. Compared with the traditional multiple fading factor strong tracking Kalman filter method, the proposed MSTSKF algorithm integrates the advantage of strong tracking Kalman filter and sequential filter, and multiple fading factor and forgetting factor for east and north velocity measurement are designed in the algorithm, respectively, which can effectively weaken the coupling relationship between the different states and increase strong robustness against process uncertainties. The simulation and experiment results show that the proposed MSTSKF method has better initial alignment accuracy and robustness than existing strong tracking Kalman filter algorithm. (shrink)

The Kalman filtering technique is considered as a part of concurrent data-processing techniques also related to detection, parameter evaluation, and identification. The adaptive properties of the filter are discussed as being related to symmetrical brain structures.

With the widespread application of electric vehicles, the study of the power lithium-ion battery has broad prospects and great academic significance. The state of charge is one of the key parts in battery management system, which is used to provide guarantee for the safe and efficient operation of LIB. To obtain the reliable SOC estimation result under the influence of simple model and measurement noise, a novel estimation method with adaptive feedback compensator is presented in this paper. The simplified dynamic (...) external electrical characteristic of LIB is represented by the one-order Thevenin equivalent circuit model and then the ECM parameters are identified by the forgetting factor recursive least squares method. Fully taking into account the feedback effect of terminal voltage innovation, the combination of adaptive extended Kalman filter and innovation vector-based proportional-integral-derivative feedback is proposed to estimate the LIB SOC. The common single proportional feedback of Kalman filter is replaced by the innovation vector-based PID feedback, which means that the multiple prior terminal voltage innovation is used in the measurement correction step of KF. The results reveal that the AEKF with PID feedback compensation strategy can improve the SOC estimation performance compared with the common AEKF, and it reveals good robust capability and rapid convergence speed for initial SOC errors. The maximum absolute error and average absolute error for SOC estimation are close to 4% and 2.6%, respectively. (shrink)
