The interaction between cavity modes and optical transitions leads to new coupled light-matter states in which the energy is periodically exchanged between the matter states and the optical mode. Here we present experimental evidence of optical strong coupling between modes of individual sub-wavelength metamaterial nanocavities and engineered optical transitions in semiconductor heterostructures. We show that this behaviour is generic by extending the results from the mid-infrared to the near-infrared. Using mid-infrared structures, we demonstrate that the light-matter coupling occurs at the (...) single resonator level and with extremely small interaction volumes. We calculate a mode volume of 4.9 × 10 from which we infer that only ~2,400 electrons per resonator participate in this energy exchange process. (shrink)

It has been customary to believe that apart from selection and abridgement Diodorus Siculus made little contribution to his Scholars have admitted the contribution of Diodorus himself when he refers to his native town Agyrium with some pride and to Sicily in general and when he occasionally records details of his own life. Beyond statements of this character, however, the tendency has been to assume that the origin of any particular statement is to be sought in the single source which (...) Diodorus was currently using, or, as others would argue, in the major source supplemented by a subsidiary source, or, as Tarn would postulate for 17, the medley of sources used by the Sicilian historian. An examination of the attribution of one item in 17 may throw some light on Diodorus as an historian. (shrink)

Background Offering financial incentives to achieve medication adherence in patients with severe mental illness is controversial. Aims To explore the views of different stakeholders on the ethical acceptability of the practice. Method Focus group study consisting of 25 groups with different stakeholders. Results Eleven themes dominated the discussions and fell into four categories: (1) ‘wider concerns’, including the value of medication, source of funding, how patients would use the money, and a presumed government agenda behind the idea; (2) ‘problems requiring (...) clear policies’, comprising of practicalities and assurance that incentives are only one part of a tool kit; (3) ‘challenges for research and experience’, including effectiveness, the possibility of perverse incentives, and impact on the therapeutic relationship; (4) ‘inherent dilemmas’ around fairness and potential coercion. Conclusions The use of financial incentives is likely to raise similar concerns in most stakeholders, only some of which can be addressed by empirical research and clear policies. (shrink)

Youths with disruptive behavior disorders and psychopathic traits showed reduced amygdala responses to fearful expressions under low attentional load but no indications of increased recruitment of regions implicated in top- down attentional control. These findings suggest that the emotional deficit observed in youths with disruptive behavior disorders and psychopathic traits is primary and not secondary to increased top- down attention to nonemotional stimulus features.

The current study examined whether Callous-Unemotional (CU) traits, a core component of psychopathy, modulate neural responses of participants engaged in a social exchange game. In this task, participants were offered an allocation of money and then given the chance to punish the offerer. Twenty youth participated and responses to both offers and the participant’s punishment (or not) of these offers were examined. Increasingly unfair offers were associated with increased dorsal anterior cingulate cortex (dACC) activity but this responsiveness was not modulated (...) by CU traits. Increasing punishment of unfair offers was associated with increased dACC and anterior insula activity and this activity was modulated by CU traits. Higher CU trait participants showed a weaker association between activity and punishment level. These data suggest that CU traits are associated with appropriate expectations of other individual’s normative behavior but weaker representations of such information when guiding behavior of the self.

The moral belief problem is that of reconciling expressivism in ethics with both minimalism in the philosophy of language and the syntactic discipline of moral sentences. It is argued that the problem can be solved by distinguishing minimal and robust senses of belief, where a minimal belief is any state of mind expressed by sincere assertoric use of a syntactically disciplined sentence and a robust belief is a minimal belief with some additional property R. Two attempts to specify R are (...) discussed, both based on the thought that beliefs are states that aim at truth. According to the first, robust beliefs are criticisable to the extent that their content fails to match the state of the world. This sense fails to distinguish robust beliefs from minimal beliefs. According to the second, robust beliefs function to have their content match the state of the world. This sense succeeds in distinguishing robust beliefs from minimal beliefs. The conclusion is that the debate concerning the cognitive status of moral convictions needs to address the issue of the function of moral convictions. Evolutionary theorising may be relevant, but will not be decisive, in answering this question. (shrink)

This Note will address the salience of a simple analogy: will privacy law be for the information age what consumer protection law was for the industrial age? At the height of industrialization, the United States market for consumer products faced instability caused by a lack of consumer competence, lack of disclosure about product defects, and advancements in technology that exacerbated the market's flaws. As this Note will show, these same causes of market failure are stirring in today's economy as well. (...) The modern economy is not one of goods but of information, and although consumers have long been aware that their personal information may have marketing value, the Internet has fundamentally changed the scope and depth of information collection, exposing more consumers than ever to injuries requiring not just a comprehensive remedy but a wholesale change in the level of care of the information industry. Just as the mass-production economy precipitated a wave of reforms in consumer protection (in part thanks to a kick-start by author Upton Sinclair), so too must the mass-information economy adapt. After demonstrating the parallels between the problems of today with those of yesterday, this Note will propose parallel solutions, particularly a consolidation of regulatory power and a new tort for breach of information privacy, which draws its inspiration from general products liability. These proposals show that rather than reinvent the wheel, modern lawmakers can (and should) answer today's problems with lessons from the last century. (shrink)

A sub-division (...) is made between those articles published by Russell during his lifetime and those posthumously by his editors. In the Collected Papers there are many further articles now published, whose appearance could not be traced during his lifetime.

R.I.G. Hughes presents a series of eight philosophical essays on the theoretical practices of physics. The first two essays examine these practices as they appear in physicists' treatises (e.g. Newton's Principia and Opticks ) and journal articles (by Einstein, Bohm and Pines, Aharonov and Bohm). By treating these publications as texts, Hughes casts the philosopher of science in the role of critic. This premise guides the following 6 essays which deal with various concerns of philosophy of physics such as laws, (...) disunities, models and representation, computer simulation, explanation, and the discourse of physics.

The most famous and successful teacher of rhetoric at Athens in the fourth century was Isocrates, and he claimed for rhetoric an educational importance which Plato considered to be unmerited and misleading. He made rhetoric the basis of his whole educational system and claimed to teach his pupils to become not only good rhetoricians but good citizens. Plato attacked both aspects of this theory of education. In the Gorgias he exposed the claim of rhetoric to be considered valuable as an (...) instrument of education by showing that rhetorical excellence had no necessary connection with moral excellence. In the Protagoras he exposed the inconsistency of those who claimed to teach men to be good citizens—to teach πολιτιк τ?νη—without an absolute standard of moral values. Even if we believe that in the Gorgias and the Protagoras, as in other dialogues, Plato is representing faithfully the constructive views of the historic Socrates, we can hardly believe that he was unaware of the contemporary relevance of those views, and it is significant that he thought fit to publish them in the form of an attack on a teacher of rhetoric and an attack on a teacher of <ολιτικ τνη At any rate it is reasonable to suppose that the Athenian reading public would expect to find such a contemporary relevance and that they would interpret these attacks as being, in some measure at least, directed against Isocrates.

It is argued that the characterization of the states of an infinite system of indistinguishable particles satisfying Bose-Einstein statistics which follows from the quantum-mechanical analog of de Finetti's theorem (2) can be used to interpret the nonuniqueness of the resolution into a convex combination of pure states of a quantum-mechanical mixed state.

Si bien la importancia de Avicena como fuente del pensamiento de Tomás de Aquino es generalmente reconocida, los detalles de esa dependencia apenas comienzan a trabajarse. Este artículo se ocupa de las enseñanzas de Avicena en lo que respecta a los “sujetos” de las ciencias teoréticas —física, matemáticas y metafísica— tal y como se presentan en la Introducción al Libro de la Curación. Posteriormente, se muestra su influencia en el comentario de Tomás de Aquino al De trinitate, de Boecio, q. (...) 5, art. 1. A través de una comparación entre Avicena y Tomás se muestra la profunda influencia que tuvo Avicena en la comprensión tomista del rango de las tres clases de ciencias teoréticas. (shrink)

Aquinas’s theology, as presented in his Scriptum, is “scientific” in the Aristotelian sense of this term. Some of its arguments for conclusions are based on theology’s “proper” principles—the articles of faith—but many others are purely rational demonstrations. As the basis for his rational arguments in theology, and in particular his treatment of the divine essence in d. 8, he introduces philosophical principles, and offers dialectical arguments for them, which are thoroughly Avicennian. In order to understand Aquinas’s commentary on d. 8, (...) then, it is not just helpful but necessary to see how he makes use of doctrines coming from the Metaphysics of Avicenna’s Book of Healing. So we look first at Aquinas’s source texts in Avicenna, and then at how he makes use of them in his commentary on the Sentences, Bk. 1, d. 8. (shrink)
