The first observations of dislocations by TEM were published in 1956. Since then the technique has been developed into an indispensable tool for the materials scientist, not only for the characterization of the extended defect structure of materials, but also for the elucidation of the mechanisms controlling their properties. To mark the 50th anniversary of the original work, this Special Issue consists of reprints of the three original papers and some 22 current state-of-the-art articles, which provide a snapshot of the (...) tremendous power and versatility of the technique at the present time. It is also hoped that this collection of papers from different areas of application and including different techniques might stimulate some cross-fertilization. In this introduction, we comment briefly on the context in which the original work was performed, trace some of the important developments that have taken place in the intervening period and identify some of the outstanding problems.

This editorial to the special issue addresses the often overlooked question of the ethical nature of social enterprises. The emerging social entrepreneurship literature has previously been dominated by enthusiasts who fail to critique the social enterprise, focusing instead on its distinction from economic entrepreneurship and potential in solving social problems. In this respect, we have found through the work presented herein that the relation between social entrepreneurship and ethics needs to be problematized. Further, we find that a range of conceptual (...) lenses and methodological approaches is valuable as the social entrepreneurship field matures. (shrink)

Scientists and laypeople alike use the sense of understanding that an explanation conveys as a cue to good or correct explanation. Although the occurrence of this sense or feeling of understanding is neither necessary nor sufficient for good explanation, it does drive judgments of the plausibility and, ultimately, the acceptability, of an explanation. This paper presents evidence that the sense of understanding is in part the routine consequence of two well-documented biases in cognitive psychology: overconfidence and hindsight. In light of (...) the prevalence of counterfeit understanding in the history of science, I argue that many forms of cognitive achievement do not involve a sense of understanding, and that only the truth or accuracy of an explanation make the sense of understanding a valid cue to genuine understanding.

Altruistic donation of organs from living donors is widely accepted as a virtue and even encouraged as a duty. Selling organs, on the other hand, is highly controversial and banned in most countries. What is the Jewish legal position on these issues? In this review it is explained that altruistic donation is praiseworthy but in no way obligatory. Selling organs is a subject of rabbinic dispute among contemporary authorities.

This essay makes the case that Livy's version of the tale of Mettius Fufetius transmits certain facts that relate to inherited ritual practices along with formulas used in early law and diplomacy. Although the author may not be fully aware of the original meaning of all he is handing down because he has simply taken materials from his sources without much critical investigation, the traditional elements are important to him because they seem to authenticate this legend about the reign of (...) Tullus Hostilius. For the moralizing historian that Livy certainly is, the treason of Mettius Fufetius and his execution at the command of the Roman king comprise the starting point of a remarkable sequence of episodes in his narrative that demonstrate the dishonorable behavior of Rome's chief rivals in Italy. The legend of Mettius Fufetius thus embodies a kind of “original sin” in the political realm, and becomes the paradigm for Rome's harsh dealing with faithless allies over the next five centuries. The essay concludes that this story typifies many Roman fabulae, insofar as they were often composed on the basis of outdated or unfamiliar idionyms, toponyms, ceremonial words and phrases, and ancient legal terms. In such fabulae characters like Tullus Hostilius and Mettius Fufetius, perhaps mere names in annals and king-lists, become the performers whose ceremonial acts turn into the foundational moments of Rome's public life.

In the Metaphysics , Aristotle examines the various meanings of concludes that its proper and primary meaning is “that which has predicates and is not predicated of anything else.” My aim in this paper is to accept this as an account of the notion of “substance,” and to free it from confusion with other notions, and then to consider whether when it is thus freed any “problem of substance” remains. I shall illustrate from the classical treatments of the subject both (...) the confusions and the development of a clearer view because it has seemed to me that exposition and criticism of those authorities sometimes show the same obscurities as the authorities themselves.

In classical antiquity Propertius' eloquence was renowned. His successor Ovid referred to the blandi praecepta Properti and to blandi…Propertius oris . Quintilian stated that to his taste the most tersus and elegans Latin elegist was Tibullus, but sunt qui Propertium malint. Martial mentioned the facundi carmen iuuenale Properti. Turn now from the opinions of ancient authors to those of some modern commentators as they try to elucidate various passages as presented in the extant manuscripts, and you encounter not the adjectives (...) blandus, tersus, elegans, and facundus, but ‘strange’, ‘obscure’, ‘odd’, ‘slovenly’, and the like. A major reason for such striking differences of opinion should be evident. Ovid, to whom Propertius was blandi oris, read a text separated from Propertius' autograph by at most a few decades. Modern scholars, however, must form their text from a few relatively late manuscripts, none earlier than c. 1200, in which Propertius' eloquence has been obscured by over twelve centuries of careless blundering and deliberate interpolation by a succession of scribes. A generally accepted example of deliberate interpolation in the Propertian archetype is found at 2.32.3-6: nam quid Praenesti dubias, o Cynthia, sortes, quid petis Aeaei moenia Telegoni? cur tua te Herculeum deportant esseda Tibur? Appia cur totiens te uia †ducit anum†? , where the name of some neighbouring town is required in the fourth verse to balance Praeneste, Tusculum, and Herculeum in the preceding three. (shrink)

The book is comprised of essays that utilize Shakespeare as a productive window into topics of contemporary social and political relevance. Its interdisciplinary qualities make the book relevant for students of political studies, literature, philosophy, cultural studies, and history.

Eighteenth-century England saw the rise of a "peculiarly English" art form—landscape gardening—and a corresponding change in attitudes toward the antural world. While the French, who lived under tyranny, had a tightly organized, restrictive gardens, the "free" English enjoyed gardens where they were at liberty to wander. John Dixon Hunt examines eighteenth-century letters, literary and critical works, biographies, paintings, prints, and drawings to trace the gradual movement from formal regularity toward a carefully calculated naturalness.

According to the theory of lexical access presented by Levelt, Roelofs & Meyer, processing of semantic–syntactic information and phonological information proceeds in a strictly discrete, serial manner. We will evaluate this claim in light of recent evidence from the literature and unpublished findings from our laboratory.

Philosophers agree that scientific explanations aim to produce understanding, and that good ones succeed in this aim. But few seriously consider what understanding is, or what the cues are when we have it. If it is a psychological state or process, describing its specific nature is the job of psychological theorizing. This article examines the role of understanding in scientific explanation. It warns that the seductive, phenomenological sense of understanding is often, but mistakenly, viewed as a cue of genuine understanding. (...) The article closes with a discussion of several new paths of research that tie the psychology of scientific explanation to cognate notions of learning, testimony, and understanding. (shrink)
