An existing industrial hydrogen generation and distribution infrastructure is described, and a number of large-scale investment projects are outlined. All of these projects have the potential to generate significant volumes of low-cost, low-carbon hydrogen. The technologies concerned range from gasification of coal with carbon capture and storage to gasification of a range of biomass streams. These biomass streams derive in turn from the supply chains that feed large liquid biofuel production plants—some operational and the others under construction. Having described how (...) such developments are coming together in a particular location to allow accelerated movement toward a hydrogen economy, this article explores the conditions under which similar acceleration could be seen in other locations.

Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

“Challenging the utility of polygenic scores for social science” is a compelling but limited critique. Phenotypic development is sensitive to both initial conditions and all subsequent states – from conception to senescence. Thus, gene-centric analyses are misleading (and often meaningless) because gene products are transformed, and their phenotypic ‘effects' combined and attenuated with successive propagations from molecular and cellular contexts to organismal and social environments.

The immediate perception after 9/11 was that we were entering a world of “new terrorism”: new actors, new tactics, new responses. And yet more than a decade later, it seems that not much has really changed, or that the changes have been contextual rather than structural. Authors have used the modifier “new” in many different ways, creating a contested and confused understanding of what terrorism is and how it appears in the world. The same applies to how one defines terrorism, (...) examines its domains and forms, delineates its actors and strategies, or compares it to state violence and fear in international relations. This raises the question of why scholars, rather than agreeing on a definition of terrorism, have focused on its many contexts, applications, and psychologies, concluding that there is a substantial and significant difference between the old and the new terrorism. However, when one tests this notion of the “new terrorism” against the case of Al-Qaeda, one finds that the tactical changes, primarily technological, as well as those in motivation and organization, are hardly new, and that the structural, ideological, and political features of terrorism have remained fundamentally the same.

In September 2008, 10 years after the untimely death of Pere Alberch (1954–1998), the 20th Altenberg Workshop in Theoretical Biology gathered a group of Pere’s students, col- laborators, and colleagues (Figure 1) to celebrate his contribu- tions to the origins of EvoDevo. Hosted by the Konrad Lorenz Institute for Evolution and Cognition Research (KLI) outside Vienna, the group met for two days of discussion. The meeting was organized in tandem with a congress held in May 2008 at the Cavanilles Institute (...) for Biodiversity and Evolutionary Biology (ICBiBE) in Valencia, Spain. The talks at the KLI were equal parts: nostalgic remembrance, excitement over new ways of thinking about old problems, and an unrepressed vitriol against the resurgence of reductionist thinking in EvoDevo. Here we highlight some of the key aspects of Pere’s life and work that informed and infused the talks. (shrink)

Résumé Dans cet article, j’explore l’idéalisme d’Érigène selon ses propres termes et conditions, en tentant de saisir la nature spécifique de son application théologique, métaphysique et épistémologique de la relation entre être et non-être. Je suggère que les idéalistes allemands ont raison de considérer Érigène comme l’un des leurs pour sa reconnaissance de l’univers comme un processus d’articulation de soi et de compréhension de soi de l’esprit divin. L’explication d’Érigène de la nature de toutes les existences comme essentiellement immatérielles, son (...) classement ontologique du monde apparemment physique, matériel et sensible sous le niveau de l’esprit et dans un sens spécifique, dépendant de l’esprit, et sa compréhension de toutes choses comme contenues dans l’esprit divin (et par extension dans l’esprit humain comme imago dei ) doivent être considérés non seulement comme constituant un système philosophique original à part entière, mais aussi comme un idéalisme dynamique et intellectualiste. La nature infinie d’Érigène implique l’interaction dialectique du caché et de la manifestation, du néant et de l’être, de l’esprit inconnu de lui-même qui en vient à la connaissance de soi dans un savoir et un non-savoir infinis.

The Crisis of European Sciences and Transcendental Phenomenology has long occupied a position amongst Edmund Husserl’s writings of almost singular renown and influence. It is easy to see why this should be so. The Crisis offered the reading public its first glimpse of a new Husserl, or at least one strikingly different in tone, mode of presentation, and thematic emphasis from the Husserl of Ideas I or Cartesian Meditations. In a seeming reversal of the Augustinian dictum that Husserl used to (...) close Cartesian Meditations,“Noli foras ire, in te redi, in interiore homine habitat veritas.” The Crisis looks outward rather than within, toward the body, history, the intersubjective community, and an analysis of the life-world, arguably Husserl’s most enduring philosophical contribution and the one with which The Crisis is most closely associated. And these concerns are framed against a backdrop o .. (shrink)

This long and complicated sentence has not been correctly translated nor clearly explained by any of the editors of the Phaedo that I have been able to consult. Bekker, Stallbaum, Wohlrab, Geddes, Wagner, Archer-Hind, Williamson, Burnet, in their notes on the passage say much that is true, but all seem to fall into certain errors. None of them has given an accurate and coherent picture of the passage as a whole. In attempting to supply such a picture I have (...) pointed out what I believe to be the mistakes of these editors, and on certain points of grammar, textual criticism, and interpretation I have some new suggestions to offer. So much emphasis on one sentence is not misplaced, for this is an important sentence, the culminating point of the first section of the dialogue, and containing in brief the essence of the ethics which Plato expounds through the mouth of Socrates. It is the peroration of Socrates' Apologia pro Vita sua, introduced by the impressive words: μακριε ειμμ^iota;α, a form of address often used by Socrates in passages of ‘pith and moment’. (shrink)

Distance education has a long and complex history. It accounts for more than one-third of all higher education students in the world and, because of its very nature, has produced some of the top graduates worldwide who were unable to study fulltime and on-campus for various reasons. One of the most prestigious graduates of the DE system was the former state president of South Africa, the late Nelson Mandela. Online learning is a form of DE and fast becoming the preferred (...) method of instruction and delivery. Critiques of online learning, and of DE itself, will argue that, because of the separation of the teacher and the student, only academic skills can be taught and learnt using this medium. The so-called ‘softer skills’ – those that focus on the development of the person – are best taught in a face-to-face, traditional environment. This article focuses on a review of DE theories and models. A particular emphasis is placed on online learning theories, and how the teaching of formational learning skills can be successfully incorporated into this educational setting. The article draws from a range of studies that have been conducted, based on conceptual and empirical research evidence from various authors. Drawing from Garrison, Anderson and Archer’s Community of Inquiry framework for online education, it presents key elements that relate to the formational training of theology students. The article examines research that both supports and cautions against online learning for formative development. It concludes by suggesting a blended model of both face-to-face and online learning, where meaningful interactions between the learner and teacher take place, is desirable. The article highlights the important role that DE can play in developing the human component of education. (shrink)

In almost any domain of endeavour, successes can be attained through skill, but also by dumb luck. An archer’s wildest shots occasionally hit the target. Against enormous odds, some fair lottery tickets happen to win. The same goes in the case of purely cognitive or intellectual endeavours. As inquirers, we characteristically aim to believe truly rather than falsely, and to attain such standings as knowledge and understanding. Sometimes such aims are attained with commendable competence, but of course, not always. (...) Epistemic luck is a species of luck which features in circumstances where a given cognitive success—in the broadest sense, some form of cognitive contact with reality—is attained in a manner that is interestingly lucky—viz., chancy, accidental or beyond our control. In the paradigmatic case, this involves the formation of a belief that is luckily true, and where the subject plausibly deserves little credit for having gotten things right. Although the literature on epistemic luck has focused predominantly on the relationship between luck and propositional knowledge—which is widely taken to exclude luck—epistemologists are increasingly exploring the compatibility of epistemic luck with other kinds of epistemic standings, such as knowledge-how and understanding.

According to I3 Theory, individuals enact aggressive behaviors when (a) instigating triggers are severe, (b) impelling forces are strong, and/or (c) inhibiting forces are weak. Archer's analysis of human sex differences in aggression could be bolstered by a careful analysis of male-female discrepancies in reactivity (or exposure) to instigating triggers, proneness toward impelling forces, and/or proneness toward inhibiting forces.

Information can be public among a group. Whether or not information is public matters, for example, for accounts of interdependent rational choice, of communication, and of joint intention. A standard analysis of public information identifies it with (some variant of) common belief. The latter notion is stipulatively defined as an infinite conjunction: for p to be commonly believed is for it to believed by all members of a group, for all members to believe that all members believe it, and so (...) forth. This analysis is often presupposed without much argument in philosophy. Theoretical entrenchment or intuitions about cases might give some traction on the question, but give little insight about why the identification holds, if it does. The strategy of this paper is to characterize a practical-normative role for information being public, and show that the only things that play that role are (variants of) common belief as stipulatively characterized. In more detail: a functional role for “taking a proposition for granted” in non-isolated decision making is characterized. I then present some minimal conditions under which such an attitude is correctly held. The key assumption links this attitude to beliefs about what is public. From minimal a priori principles, we can argue that a proposition being public among a group entails common commitment to believe among that group. Later sections explore partial converses to this result, the factivity of publicity and publicity from the perspective of outsiders to the group, and objections to the aprioricity of the result deriving from a posteriori existential presuppositions.

Living out of silence, out of a fully functioning, lovingly attentive mind, and not just out of thought, out of a partially functioning mind, is requisite for depth or profundity in living or relating. A fully attentive, truly silent or meditative mind sees that there is real dualism of time and the timeless and that time and the timeless each has its own unique value. The timeless, or real silence, that which alone can make for depth in one's living and (...) relating, can be there only when, in one's awareness, time and all that is related to time, have come to an end. An examination of a wide variety of statements made by writers, both past and present, shows that these understandings are seldom there in contemporary writings, just as they were not there in writings that have come down to us from the past. 'Living beyond the One and the Many' invites readers to consider the possibility that what is presented in it can bring deep meaning to one's way of living in the world"--Publisher's description, back cover.

Should we regard Jennifer Lackey’s ‘Creationist Teacher’ as understanding evolution, even though she does not, given her religious convictions, believe its central claims? We think this question raises a range of important and unexplored questions about the relationship between understanding, factivity and belief. Our aim will be to diagnose this case in a principled way, and in doing so, to make some progress toward appreciating what objectual understanding—i.e., understanding a subject matter or body of information—demands of us. Here is the (...) plan. After some ground clearing in §1, §2 outlines and motivates a plausible working model—moderate factivity—for characterising the sense in which objectual understanding should be regarded as factive. §3 shows how the datum that we can understand false theories can, despite initial suggestions to the contrary, be assimilated straightforwardly within the moderate factivity model. §4 highlights how the inverse kind of case to that explored in §3—viz., a variant of Lackey’s creationist teacher case—poses special problems for moderate factivity. With reference to recent work on moral understanding by Hills, §5 proposes a solution to the problem, and §6 attempts to diagnose why it is that we might originally have been led to draw the wrong conclusion.

Edmund Husserl is the founder of phenomenology. The Logical Investigations is Edmund Husserl's most famous work and has had a decisive impact on the direction of twentieth century philosophy. This is the first time both volumes of this classic work, translated by J.N. Findlay, have been available in paperback. They include a new introduction by Dermot Moran, placing the Logical Investigations in historical context and bringing out its importance for contemporary philosophy.

The achievements of the textile industry in Roman Britain are often underestimated as a result of the meagreness of our available evidence. The Edict on maximum prices issued by Diocletian in A.D. 301 shows that British capes commanded high prices on the markets of the Empire, and that in the late third century A.D. British rugs were the best in the world. In view of the competition from the traditional centres of rug manufacture in the East, this is an astonishing (...) achievement. (shrink)
