Physicalists motivate their position by posing a problem for the opposition: given the causal completeness of physics and the impact of the mental (or, more broadly, the seemingly nonphysical) on the physical, antiphysicalism implies that causal overdetermination is rampant. This argument is, however, equivocal in its use of 'physical'. As Scott Sturgeon has recently argued, if 'physical' means that which is the object of physical theory, completeness is plausible, but the further claim that the mental has a causal impact on (...) the physical is no longer so evident. In this paper I assess the damage due to the ambiguity of 'physical' and provide a repair to the overdetermination strategy. (shrink)

Before Euro-American settlement, many Native American nations intercropped maize (_Zea mays_), beans (_Phaseolus vulgaris_), and squash (_Cucurbita pepo_) in what is colloquially called the “Three Sisters.” Here we review the historic importance and consequences of rejuvenation of Three Sisters intercropping (3SI), outline a framework to engage Native growers in community science with positive feedbacks to university research, and present preliminary findings from ethnography and a randomized, replicated 3SI experiment. We developed mutually beneficial collaborative research agendas with four Midwestern US Native (...) American nations. Ethnographic data highlighted a culturally based respect for 3SI as living beings, the importance it holds for all cultural facets of these Native nations, and the critical impact the practice has on environmental sustainability. One concern expressed by Native growers during ethnographic research was improving soil health—part of the rationale for establishing the 3SI agronomic experiment. To address this, we collaboratively designed a 3SI experiment. After 1 year, 3SI increased short-term soil respiration by 24%, decreased salt-extractable nitrate by 54%, had no effect on soil microbial biomass (but increased its carbon-to-nitrogen ratio by 32%) compared to the average of monoculture crops. The overarching purpose of this collaborative project is to develop a deeper understanding of 3SI, its cultural importance to Native communities, and how reinvigorating the practice—and intercropping in general—can make agroecosystems more sustainable for people and the environment.

J. Angelo Corlett’s response to Leigh Turner defends the current practice of anonymous refereeing in scholarly journals. In reply to him: a slightly refined proposal for signed referees’ reports, with temporarily blind refereeing, would restore to the process of publication, in philosophy at least, the sense of responsibility for rational debate, cooperation, mutual criticism, and simple courtesy which is expected among colleagues in public academic relations, and would also allow more credit for the difficult task for refereeing. Personal observation of (...) the quality of referees’ reports suggests that a gathering of anecdotal evidence would show the need for reform. (shrink)

This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health Systems, 1991] completed a gambling task [Cognition 50 (1994) 7] and the intradimensional/extradimensional (ID/ED) shift task [Nature 380 (1996) 69]. On the gambling task, psychopathic participants showed a global tendency to choose disadvantageously. Specifically, they showed an (...) impaired ability to show learning over the course of the task. On the ID/ED task, the performance of psychopathic individuals was not significantly different from incarcerated controls on attentional set-shifting, but significant impairments were found on response reversal. These results are interpreted with reference to an OFC and amygdala dysfunction explanation of psychopathy. (shrink)

Several recent papers which purport to substantiate or negate arguments in favor of certain theories of absolute space have been based on fallacious principles. In this paper we discuss three related instances, indicating where misconceptions have arisen. We establish, contrary to popular belief, that the classical Lorentz ether theory accounts for all the experimental evidence which supports the special theory of relativity. We demonstrate that the ether theory predicts the null results obtained from pulsar timing and Mössbauer experiments. We conclude (...) that a measurement of the one-way velocity of light has physical meaning within the context of the Lorentz theory, and argue that an adequately designed experiment to measure the one-way velocity of light should be attempted.

Notice is given of the discovery of two reports and an accompanying manuscript map by Andrew Ramsay, on the geology of the St David's area, Pembrokeshire. This adds to previously published information on early geological work in this important region: Ramsay's report throw some light on his attitude towards Murchison's ideas on Welsh stratigraphy. The map is the earliest known version of the Survey's St David's sheet.

Christopher Miles Coope offers a letter, drafted by Helen Taylor but certified by Mill, in which Mill asserts the duty to vote, as evidence that he could not have regarded harmfulness to others as a necessary condition of moral wrongness. But it is clear that Mill regarded the duty to vote as one of imperfect obligation, and the wrongness of not fulfilling it as a matter roughly of not doing enough, in this case not doing one's fair share. He has (...) room for the common-sense harmlessness of staying at home. At the same time he grounds political duties in the harmfulness of neglecting the power of legislation and in the possibility, consistently maintained, that one can harm by inaction. Mill's view, central to his relation between morality and liberty, remains at work here, while also suggesting reflections on the peculiarity of his conception of harm. (shrink)
