Aging is associated with declines in sensorimotor function. Several studies have demonstrated that transcranial direct current stimulation, a form of non-invasive brain stimulation, can be combined with training to mitigate age-related cognitive and motor declines. However, in some cases, the application of tDCS disrupts performance and learning. Here, we applied anodal tDCS either over the left prefrontal cortex, right PFC, supplementary motor complex, the left M1, or in a sham condition while older adults practiced a Discrete Sequence Production, an explicit (...) motor sequence, task across 3 days. We hypothesized that stimulation to either the right or left PFC would enhance motor learning for older adults, based on the extensive literature showing increased prefrontal cortical activity during motor task performance in older adults. Contrary to our predictions, stimulation to the right and left PFC resulted in slowed motor learning, as evidenced by a slower reduction rate of reduction of reaction time and the number of sequence chunks across trials relative to sham in session one and session two, respectively. These findings suggest an integral role of the right PFC early in sequence learning and a role of the left PFC in chunking in older adults, and contribute to mounting evidence of the difficultly of using tDCS in an aging population.

Do American Christians have hope in community, within their congregations and in the wider society, and should they? Putting my fieldwork in five church communities in dialogue with Thomas Aquinas’s account of hope and with insights from congregational studies, I answer yes to both questions. Christian hope is best understood and lived not simply as a theological virtue but as a social virtue. In this understanding, connections forged with others, both inside and outside a church, can develop a community’s realistic, (...) forward-looking trust in social relationships and in the fate of society. I suggest four guidelines for church practices to build up social hope and make it more effectual. (shrink)

For a long time before the ‘climategate’ emails scandal of late 2009 which cast doubt on the propriety of science underpinning the Intergovernmental Panel on Climate Change, attention to climate change science and policy has focused solely upon the truth or falsity of the proposition that human behaviour is responsible for serious global risks from anthropogenic climate change. This article places such propositional concerns in the perspective of a different understanding of the relationships between scientific knowledge and public policy issues (...) from the conventional ‘translation’ model, in which prior scientific research and understanding is communicated and translated into corresponding policies — or not, if it remains disputed and overly uncertain. Explaining some of the key contingencies and bases for uncertainty in IPCC climate projections and human influences, I show how social and technical analysis of climate science is not about denial of the scientific propositional claims at issue, but about understanding the conditional and essentially ambiguous epistemic character of any such knowledge, however technically sophisticated and robust it may be. Contrary to conventional wisdom, it is entirely plausible that existing scientific representations of climate change and its human causes may understate the risks induced by prevailing social-economic processes rather than exaggerate them. As the article shows, the public meanings given to climate science, and to ‘the climate problem’, and thus also the public culture which that knowledge is supposed to inform, are themselves already in key respects presumed and imposed by the science and its framing. This gives rise to perverse effects on public readiness to take informed democratic responsibility for ‘the global climate problem’, and associated cross-cutting issues which existing scientific framings of public policy erase from view.

Dominant social sciences approaches to complexity suggest that awareness of complexity in late-modern society comes from various recent scientific insights. By examining today’s plant and human genomics sciences, I question this from both ends: first suggesting that typical public culture was already aware of particular salient forms of complexity, such as limits to predictive knowledge ; second, showing how up-to-date genomics science expresses both complexity and its opposites, predictive determinism and reductionism, as coexistent representations of nature and scientific knowledge. I (...) suggest we can understand this self-authored epistemic confusion in modern science by avoiding ‘the usual suspects’ – fading simpler discourses left over from previous scientific times; media oversimplifications; or the need to ‘simplify’ to essentials, for ignorant publics – and looking instead at the silent imaginations of extra-scientific reference groups reflected and projectively performed in scientific discourses-practices themselves. Thus contradictions of complex scientific understandings are systematically created by science’s own embodiment of epistemic commitments influenced by commercial cultures, and by imagined publics who are important new constructed objects of institutional scientific concerns – over authority and trust. New dimensions of complexity thus come alive through paying attention to neglected tacit dimensions of science–society interrelations. (shrink)

This article argues that, in public and policy contexts, the ways in which many scientists talk about uncertainty in simulations of future climate change not only facilitates communications and cooperation between scientific and policy communities but also affects the perceived authority of science. Uncertainty tends to challenge the authority of chmate science, especially if it is used for policy making, but the relationship between authority and uncertainty is not simply an inverse one. In policy contexts, many scientists are compelled to (...) talk about uncertainty but do not wish to imply that uncertainty is a serious challenge to the authority of scientific knowledge or to its substantial use in policy making. "Boundary-ordering devices, " the contextual discursive attempts to reconcile uncertainty and authority in science, depend critically for their success on their "dual" interpretation: at a general level across a boundary and differently on either side of it. The authors empirically identify a range of such boundary-ordering devices in the climate field. (shrink)

Andrew Webster proposes that science and technology studies align itself more thoroughly with practical policy contexts, actors and issues, so as to become more useful, and thus more a regular actor in such worlds. This commentary raises some questions about this approach. First, I note that manifest influence in science or policy or both should not become-by default, or deliberately-a criterion of intellectual quality for STS research work. I distinguish between reflective historical work, which delineates the contingent ways in which (...) existing policy and technoscientific cultures have become entrenched as such inscribed and perhaps dysfunctional institutional habit; and, work of the kind that Webster's three case studies exemplify, that is, geared to influence policy-decision outcomes. I suggest that many of the important issues facing STS-and "policy"-are not explicit "policy-decision issues" as such, but implicit "policy syndromes" that need naming, diagnosing and open, if enforced, institutional reflection.

A field K in a ring language $\mathcal {L}$ is finitely undecidable if $\mbox {Cons}(T)$ is undecidable for every nonempty finite $T \subseteq {\mathtt{Th}}(K; \mathcal {L})$. We extend a construction of Ziegler and (among other results) use a first-order classification of Anscombe and Jahnke to prove every NIP henselian nontrivially valued field is finitely undecidable. We conclude (assuming the NIP Fields Conjecture) that every NIP field is finitely undecidable. This work is drawn from the author’s PhD thesis [48, Chapter 3].

It is morally negligent or reckless to believe without sufficient evidence. The foregoing proposition follows from a rule that is a modified expression of W. K. Clifford's ethics of belief. Clifford attempted to prove that it is always wrong to believe without sufficient evidence by advancing a doxastic counterpart to an act utilitarian argument. Contrary to various commentators, his argument is neither purely nor primarily epistemic, he is not a non-consequentialist, and he does not use stoicism to make his case. (...) Clifford's conclusion is a universal generalisation that is in a precarious position because of potential counterexamples. But the counterexamples do not preclude a rule against going beyond the available evidence and it is worthwhile making a moral case for such a rule. (shrink)

Color coded terror alerts, invasion, drone war, rampant surveillance: all manifestations of the type of new power Brian Massumi theorizes in _Ontopower_. Through an in-depth examination of the War on Terror and the culture of crisis, Massumi identifies the emergence of preemption, which he characterizes as the operative logic of our time. Security threats, regardless of the existence of credible intelligence, are now felt into reality. Whereas nations once waited for a clear and present danger to emerge before using (...) force, a threat's felt reality now demands launching a preemptive strike. Power refocuses on what _may_ emerge, as that potential presents itself to feeling. This affective logic of potential washes back from the war front to become the dominant mode of power on the home front as well. This is ontopower—the mode of power embodying the logic of preemption across the full spectrum of force, from the “hard” to the "soft". With _Ontopower_, Massumi provides an original theory of power that explains not only current practices of war but the culture of insecurity permeating our contemporary neoliberal condition.

We live in a world of gross inequality. While a minority live in unprecedented wealth, the majority live in considerable poverty. Though much money has been given in aid by the rich countries to the poor, both by secular and Christian institutions, there has been much criticism that much of that aid has been wasted, indeed much of it has been actually harmful. But while there is truth in some of these criticisms, there is also increasing evidence of where community (...) development has been effective, and sustainable. This article considers the strengths and limitations, and examples, of such a church-based, bottom-up, approach to transforming the physical and spiritual needs of the individuals and their communities. We will see that it is, arguably, the only way that truly holistic transformation can be delivered, and consider some of the implications for Western Christians and Christian NGOs. (shrink)

Drawing on interviews and observational work with practicing U.K. plant scientists, this article uses Michel Callon's work as a tool to explore the issue of collaboration between academic science and business, in particular, calls by the Biotechnology and Biological Sciences Research Council for a return to “public good” plant science. In an article titled “Is Science a Public Good?” Callon contributed to the debate about the commercialization of science by suggesting that commercialization and the public good need not be incompatible. (...) Moving away from arguments that center on the effects of business involvement in science, he suggested that analysts use another model, centered on “diversity.” This model allows us to ask what society might want from science, what public good science might look like, and how public good science can be ensured while also recognizing that science cannot be easily separated from the market.

We show how Richard Jeffrey's The Logic of Decision provides the proper formalism for calculating expected fitness for correlated encounters in general. As an illustration, some puzzles about kin selection are resolved.

The career of John Jackson , Arian theologian and controversialist, provides a key to unlocking the early reception and quick collapse of a Newtonian natural apologetic originally developed by Samuel Clarke. The importance of friendship and discipleship in eighteenth-century intellectual enquiry is emphasised, and the links between Newton and his followers are traced alongside those of a group of Cambridge Lockeans, led by Jackson’s direct contemporary Daniel Waterland, who proved instrumental in the initial dismantling of Clarke’s brand of Newtonian apologetic. (...) The controversial context of this engagement is shown to have been largely provided by the religiously compromising rise of freethinking, and Tindal’s Christianity as old as the creation signalled the dangers to proponents of natural religion as an adjunct of Christian apologetic in such a heated atmosphere. Religious division of the sort that resulted paradoxically played into the hands of the freethinkers in the anticlerical atmosphere of the 1730s, and accusations were exchanged between Newtonians and Lockeans accordingly. The dynamic of England’s Enlightenment experience is, then, a complicated one, and, as the career and writings of Jackson and William Whiston demonstrate, it was one which absorbed as well as repudiated ‘enthusiasm’.Author Keywords: Newtonianism; Enlightenment; Enthusiasm; Natural religion; Arianism; John Jackson.

This essay argues, following an insight of Burckhardt, that the philosophy of history is a ‘centaur’, and that it has a tendency to hinder rather than to encourage the practice of history. It challenges many of the presuppositions of Bevir's study, demonstrating that The Logic of the History of Ideas is not, in any meaningful sense, an historically minded work. The ‘logic’ of the essay looks to the arts, especially literature and music, as providing genuinely illuminating parallels to the discipline (...) involved in the practice of intellectual history. History cannot be understood as a process of philosophical abstraction; pertinent examples are of its essence, and plurality is therefore central to its richly textured nature. It still has much to learn from the reflexive procedures of anthropology. By examining the idea of ‘tradition’ the essay demonstrates that ‘the past’ is never dead, and that the relationship between texts is a living process: the intellectual historian is him/herself an artist, and his/her task is no less demanding than that of the creative artist, and it is always humblingly provisional.

In 'The ethics of belief and Christian faith as commitment to assumptions', Rik Peels attacks the views that I advanced in 'Christianity and the ethics of belief'. Here, I rebut his criticisms of the claim that it is wrong to believe without sufficient evidence, of the contention that Christians are committed to that claim, and of the notion of that faith is not belief but commitment to assumptions in the hope of salvation. My original conclusions still stand.

There is an alternative to the type of moral standing that hypothetically supervenes on other, base or subvenient, properties. Attributed moral standing results when people who have a naturally selected belief that they are worthy of moral consideration negotiate with others with the aim of being acknowledged as having moral standing and are successful. They could successfully negotiate with people who possessed supervenient moral standing. In a hypothetical evolutionary competition with the latter, they would replace them entirely. The result would (...) be a moral community that excludes animals but that includes human infants. Membership in the moral community ends up being what it would be if moral standing supervened on the property of being human. The supervenience doctrine is also criticized on other grounds. (shrink)

Rational self-interest is often seen as being at the heart of liberal economic theory. In _The Power at the End of the Economy_ Brian Massumi provides an alternative explanation, arguing that neoliberalism is grounded in complex interactions between the rational and the emotional. Offering a new theory of political economy that refuses the liberal prioritization of individual choice, Massumi emphasizes the means through which an individual’s affective tendencies resonate with those of others on infra-individual and transindividual levels. This nonconscious (...) dimension of social and political events plays out in ways that defy the traditional equation between affect and the irrational. Massumi uses the Arab Spring and the Occupy Movement as examples to show how transformative action that exceeds self-interest takes place. Drawing from David Hume, Michel Foucault, Gilles Deleuze, Niklas Luhmann and the field of nonconsciousness studies, Massumi urges a rethinking of the relationship between rational choice and affect, arguing for a reassessment of the role of sympathy in political and economic affairs.

To argue that “ought” implies “can,” one can appeal to general principles or to intuitions about specific cases. One general truism that seems to show that “ought” implies “can” is that obligations must be able to guide action, and putative obligations that are unfulfillable are unable to do so. This paper argues that obligations that are unfulfillable can still guide action, and that moral theories which reject the principle that “ought” implies “can” are actually better able to account for how (...) obligations guide than theories which endorse “ought” implies “can.” The paper also argues that any intuitions about specific cases that seem to provide evidence that “ought” implies “can” do not actually give us this evidence. Rather, these intuitions pose similar problems for theories which accept “ought” implies “can” as they pose for theories which reject the principle. Some theories which reject “ought” implies “can” will fit our intuitions at least as well, if not better, than theories which accept it. So, intuitions do not favor accepting that “ought” implies “can,” and appeal to general principles favors its denial. (shrink)

I have some of my properties purely in virtue of the way I am. (My mass is an example.) I have other properties in virtue of the way I interact with the world. (My weight is an example.) The former are the intrinsic properties, the latter are the extrinsic properties. This seems to be an intuitive enough distinction to grasp, and hence the intuitive distinction has made its way into many discussions in ethics, philosophy of mind, metaphysics and even epistemology. (...) Unfortunately, when we look more closely at the intuitive distinction, we find reason to suspect that it conflates a few related distinctions, and that each of these distinctions is somewhat resistant to analysis.

The development of Christian NGOs over the second half of the 20th century has been one of the great stories of the church. At a time when the evangelical church in the West had gone into reverse, away from a holistic gospel, emphasising personal salvation alone and leaving the social gospel to the more liberal and ecumenical branch of the church, individual Christians had responded to the needs of a suffering world by forming CNGOs to tackle the relief and development (...) problems around the world. This paper outlines the background to the CNGO movement, from earliest biblical times, describes the growth of the movement, with special reference to Tearfund, and then discusses the issues and challenges currently being faced. It concludes that by working through the local churches the mission of CNGOs can be holistic, and bring hope to the world. (shrink)

This paper argues that the church should give especial care to the needs of older folk in their communities, needs that are often neglected. It analyses why such folk have especial needs in our contemporary society and suggests practical ways that churches can and should respond. It summarises particular approaches to learning to grow old, and to die well, given by various authors who have had experience in these areas. It considers the problem of pain and suffering and suggests a (...) dualistic approach that can give comfort. (shrink)

This article addresses the challenge philosophical realism poses to the field of rhetoric by exploring the possibility of symbolic communion with nonhuman entities. As a matter of framing, I invoke Timothy Morton’s concept of the hyperobject to better understand the complexities of communicating with and about sublime nonhuman objects such as black holes. I then delineate how the stylistic modality of the weird best exploits the chasm between autonomous thingness and human presentation that is a primary source of consternation for (...) rhetorical realism. Finally, I draw from Kathe Koja’s novel The Cipher to reconsider a bizarre rhetoric of black holes which displays the omnipresent tension of accessible-alterity characteristic of the struggle to rhetorically breach the nonhuman world.

[Brian P. McLaughlin] In recent years, some philosophers have claimed that we can know a priori that certain external world skeptical hypotheses are false on the basis of a priori knowledge that we are in certain kinds of mental states, and a priori knowledge that those mental states are individuated by contingent environmental factors. Appealing to a distinction between weak and strong a priority, I argue that weakly a priori arguments of this sort would beg the question of whether (...) the skeptical hypothesis under assessment is true, and that the prospect of a sound strongly a priori argument of this sort seems dim. \\\ [David Owens] Contemporary discussion of scepticism focuses on the possibility that most or all of our beliefs might be false. I argue that the hypothesis of massive falsity and the associated 'problem of the external world' are inessential to the scepticisms of Descartes and Hume. What drives Cartesian and Humean scepticism is the demand for certainty: any possibility of error, however local, must be ruled out before we can claim either justified belief or knowledge. Contemporary philosophers have ignored this form of scepticism because they doubt that the demand for certainty can be motivated. But Descartes provides a sound motivation for this demand in the Meditations. (shrink)
