It has been reported that behavior of experts and novices in various sporting tasks is impervious to the introduction of blur. However, studies have used diverse methods of blurring the visual stimulus, and tasks that did not always preserve the normal perception-action coupling. In the current study, we developed a novel experimental protocol to examine the effect of different levels of Gaussian blur on interception performance and eye gaze data using an immersive VR task. Importantly, this provided a realistic simulation (...) of a real-world boxing scenario in which expert combat athletes experienced a first-person, adaptive viewpoint of the visual environment, which could be blurred according to their gaze location. We found that participants exhibited similar interception performance in the presence of central blur or peripheral blur compared to a control condition with no blur. However, interception performance was significantly better with a central blur compared to peripheral blur. Eye gaze data indicated that although participants fixated at similar areas of interest irrespective of the presence of blur, fixation duration was significantly longer with a strong level of blur in the peripheral viewing condition than all levels of central blur and the control condition. These findings can be explained by relocating attention to different areas of the environment, which thereby influenced the perception of salient information. Participants also performed better on the first punch of a sequence preceded by a foot feint compared to arm feint or no feint. Still, irrespective of feint type, performance was significantly better on the second and third punch compared to the first punch. These findings are consistent with participants using additional information from the opponent's body movements and situational probabilities to increase performance as the sequence of punches developed. Overall, these are the first evidence for the use of VR as a means to examine gaze-contingent manipulations of the environment, and hence highlight the potential for facilitating learning and transfer to a real sporting situations.

Loot Boxes, i.e., virtual items embedded within video games with numerous features reminiscent of gambling, are increasingly widespread among adolescents. LB use is associated with problem gambling in youth, but few studies have been conducted on the association between LB use and gambling behavior considering adolescents. Thus, the mechanisms underlying this relationship are not clear. As LB use is a significant and positive risk factor for video gaming severity, and video gaming is associated with problem gambling, we hypothesized that (...) LB use would be related to gambling frequency and problem gambling through the intermediary role of video gaming frequency and problem video gaming. We tested our hypothesis before COVID-19-pandemic-related lockdown and during COVID-19-pandemic-related lockdown, in Italy. Study 1 was conducted with 1,078 high school students before COVID-19-pandemic-related lockdown, and Study 2 was conducted with 1,204 high school students during COVID-19-pandemic-related lockdown. A path analysis was carried out to analyze the significance of indirect effects from LB use to gambling behavior and problem gambling through video gaming and problem video gaming. In both the studies, results showed that LB use exerted significant and positive direct effects on video gaming frequency, problem video gaming, and gambling frequency. Moreover, LB use had indirect significant and positive effects on problem gambling through video gaming frequency, problem video gaming, and gambling frequency. Findings attest that LB use can be related to problem gambling through a greater involvement in videogames. Thus, a specific subtype of young gamblers can develop Gambling Disorder symptoms from the use of LBs and through an intense use of video games. Practical implications for prevention and treatment are discussed. (shrink)

Robotic systems consisting of a neuron culture grown on a multielectrode array which is connected to a virtual or mechanical robot have been studied for approximately 15 years. It is hoped that these MEA-based robots will be able to address the problem that robots based on conventional computer technology are not very good at adapting to surprising or unusual situations, at least not when compared to biological organisms. It is also hoped that insights gained from MEA-based robotics can have (...) applications within human enhancement and medicine. In this paper, I argue that researchers within this field risk overstating their results by not paying enough attention to fundamental challenges within the field. In particular, I investigate three problems: the coding problem, the embodiment problem and the training problem. I argue that none of these problems have been solved and that they are not likely to be solved within the field. After that, I discuss whether MEA-based robotics should be considered pop science. Finally, I investigate the ethical aspects of this research. (shrink)

Virtual reality (VR) is the computer simulation of a three‐dimensional environment that a person can interact with using special electronic equipment, such as a headset with an integrated display. Often coupled with VR, exergames are video games that involve physical exercise. Little is known regarding the chronic effects of exergaming through VR chon cognitive functions. Eleven young participants were enrolled in this crossover exploratory study. They had to follow two trainings of 5 consecutive days, 15 min per day, interspaced (...) by a 1‐month washout period. Trainings were performed in a random order: (1) a video training using shadow boxing fitness videos (SBV) and (2) a VR training using a three‐dimensional game where the aim is to cut moving cubes with a sword in each hand. Before and after each training period, a battery of cognitive tests was performed to assess executive functions, such as attention (change blindness), reaction time, response inhibition (go/no‐go, Stroop task), or flexibility (trail making test). Fine motor skills were also evaluated through a Fitt's task. No effect of the SBV training was observed on any of the cognitive functions tested. On the contrary, a significant increased performance in selective attention and observation tests was found after VR training, as well as in inhibitory processes (Stroop and go/no‐go). Other performances were unaffected by either VR or SBV training. The present study argues that VR exergaming is a promising tool to promote cognitive enhancement but targets specific functions according to the type of interface/game that is used. (shrink)

Wegner makes an excellent case that our sense of ownership of our actions depends on multiple factors, to such an extent that it could be called virtual or even illusory. However, two other core functions of will are initiation of movement and maintenance of resolution, which depend on our accurate monitoring of them. This book shows that will is not an imponderable black box but, rather, an increasingly accessible set of specific functions.

Research in political science currently utilizes a no-nonsense principle. Little time is invested in complicated theoretical constructions. Only the facts matter. What is examined is the way in which certain ideas and behaviours cohere with other ideas and behaviours, and the explanations offered for this coherenece are usually quite brief. In some cases, the tone used in an explanation can make us suspect that there are complex underlying presuppositions.Some critics seem to base their opinions on a more optimistic liberal view (...) of human nature, while others have a pessimistic view of the quality of journalism, the disappearance of social capital, the short-sightedness of the political parties and the various popular forms of information and communication. Theoretical presuppositions are seldom the immediate focus of discussion. Facts are opposed to facts, since ultimately facts are the only basis for legitimate argument.Indeed, discussions that are not about facts are of little benefit to anyone. Predictions of doom with no basis in reality can hardly lead to a constructive dialogue. Facts, however, are always interpreted facts, and in order to interpret accurately, one needs theory. When actors are considered as individual black boxes who produce a certain output when confronted with a given input, then it is impossible to explain why people who watch a lot of television also tend to believe that they are powerless politically. And it is even more difficult to provide reasons for why viewers of soaps, game shows and sitcoms are more likely to harbour feelings of insecurity than viewers of news programmes or films, particularly since the latter exhibit images of aggression and conflict.Likewise, it remains unclear why commercial broadcasters give more airtime to reports of crime, or why the presentation of political issues in black and white terms is so rewarding at the polls. In this paper, I will first of all present a broad theoretical perspective, and subsequently come back to the facts. (shrink)

The so-called new economy based on the global network of digitalized communication was welcomed as a platform of innovations and as a vehicle of advancement of democracy. The concept of virtuality captures the essence of the new economy: efficiency and free access. In practice, the new economy has developed into an heterogenic entity dominated by practices such as propagation of trust and commitment to standards and standard-like technological solutions; entrenchment of locally strategic subsystems; surveillance of unwanted behavior. Five empirical cases (...) within the present field of opposing forces serve as fuel for reflection: football hooliganism, sand-boxing, digital vulnerability of nuclear technology, sensitivity of studio projects, and streamlining academic computing. The main argument of the article is that a historic re-materialization is taking place within the new economy. This means cognitive as well as material divisions. Incommensurability in science is comparable with product incompatibility from the point of view of their implications to the users of knowledge and computers. Hype and banal attached to the new media are related to two ways of assessing social capital: as a means of peaceful functionality or a condition for cultural conflicts. The paper ends in proposing that there is a re-materialization of the virtual now taking place especially on the meta-level of the system. (shrink)

If well-designed, the results of a Randomised Clinical Trial can justify a causal claim between treatment and effect in the study population; however, additional information might be needed to carry over this result to another population. RCTs have been criticized exactly on grounds of failing to provide this sort of information Evidence, inference and enquiry. Oxford University Press, New York, 2011), as well as to black-box important details regarding the mechanisms underpinning the causal law instantiated by the RCT result. On (...) the other side, so-called In Silico Clinical Trials face the same criticisms addressed against standard modelling and simulation techniques, and cannot be equated to experiments Philosophy of molecular medicine: foundational issues in research and practice, Routledge, New York, 2017; Parker in Synthese 169:483–496, 2009; Parke in Philos Sci 81:516–536, 2014; Diez Roux in Am J Epidemiol 181:100–102, 2015 and related discussions in Frigg and Reiss in Synthese 169:593–613, 2009; Winsberg in Synthese 169:575–592, 2009; Beisbart and Norton in Int Stud Philos Sci 26:403–422, 2012). We undertake a formal analysis of both methods in order to identify their distinct contribution to causal inference in the clinical setting. Britton et al.’s study :E2098–E2105, 2013) on the impact of ion current variability on cardiac electrophysiology is used for illustrative purposes. We deduce that, by predicting variability through interpolation, ISCTs aid with problems regarding extrapolation of RCTs results, and therefore in assessing their external validity. Furthermore, ISCTs can be said to encode “thick” causal knowledge —as opposed to “thin” difference-making information inferred from RCTs. Hence, ISCTs and RCTs cannot replace one another but rather, they are complementary in that the former provide information about the determinants of variability of causal effects, while the latter can, under certain conditions, establish causality in the first place.

Recognized in his day as a man of letters equaling Rousseau and Voltaire in France and rivaling Samuel Johnson, David Hume passed from favor in the Victorian age--his work, it seemed, did not pursue Truth but rather indulged in popularization. Although Hume is once more considered as one of the greatest British philosophers, scholars now tend to focus on his thought rather than his writing. To round out our understanding of Hume, M. A. Box in this book charts the interrelated (...) development of Hume's literary ambitions, theories of style, and compositional practice from his Treatise in 1739 through the Enquiries. In so doing, Box makes the case for Hume's career-long concern with the presentational modes of reaching an audience for his philosophical writings. Hume reacted to the popular failure of his masterpiece, A Treatise of Human Nature, Box suggests, by self-consciously exploring strategies in his subsequent works for agreeably bringing his readership to participate in the act of philosophizing. Combining a sensitive grasp of the ways Restoration period and eighteenth-century writers conceived the relations between rhetoric and philosophy with sound readings of particular texts, Box shows how Hume's literary concerns went beyond matters of style to involve persona, structure, and doctrine. While this book helps explain long-standing ambiguities surrounding Hume, especially by pointing out the tension between his created persona and his own voice, it also serves as an excellent introduction to his philosophy.

Assisted dying is a divisive and controversial topic and it is therefore desirable that a broad range of interests inform any proposed policy changes. The purpose of this study is to collect and synthesize the views of an important stakeholder group—namely people with disabilities —as expressed by disability rights organisations in Great Britain. Parliamentary consultations were reviewed, together with an examination of the contemporary positions of a wide range of DROs. Our analysis revealed that the vast majority do not have (...) a clear public stance; those that do exhibit a significant diversity of opinion. DROs opposing legislation on assisted dying have argued that it would be premature, misguided, inequitable and culturally undesirable. Some specify conditions that would have to be satisfied before they could support legalisation, such as radical improvements in health and social care services and the elimination of discrimination against PwD. DROs supporting assisted dying maintain that a change in the law would promote autonomy, end intense suffering, can be delivered safely and is supported by the DRO’s membership. The discussion considers the reasons why several DROs adopt a neutral stance and the argument is made that, whatever their overarching stance on the issue, DROs need to be involved in the policy debate so that the crucial perspectives of PwD are heard and addressed. This is an important message for countries around the world that permit, or are considering legalising, assisted dying. (shrink)

The UK Medical Research Council, in order to further its mission of maintaining and improving human health, supports a substantial number of clinical trials on a wide variety of medical questions; some of these trials involve the use of placebos as controls or to maintain blinding. Before providing support, proposed trials are carefully reviewed to assess scientific quality, and to determine whether a placebo is required and is ethical — in addition to ethics review by independent Research Ethics Committees. Some (...) questions such as the choice of placebos in trials in developing countries, in surgical trials and those involving alternative medicine require consideration of additional, specific issues. Involvement of consumers in MRC work has been increasing and includes the establishment of a Consumer Liaison Group; members of this group comment on patient information leaflets for clinical trials, helping to improve patient understanding of trials and ensuring topics like placebo use are explained clearly. Views differ on the value of placebos in clinical care and on their mechanism of action; continuing research is helping to clarify the issues. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 2, November 2003, pp. 223-266 A Diplomatic Transcription of Hume's "volunteer pamphlet" for Archibald Stewart: Political Whigs, Religious Whigs, and Jacobites M. A. BOX, DAVID HARVEY, AND MICHAEL SILVERTHORNE Many scholars interested in David Hume will have encountered his defense of the beleaguered Archibald Stewart as it appears in an appendix in John Valdimir Price's The Ironic Hume (Austin: University of Texas Press, 1965). (...) Additionally they might know of Price's discussion for The Biblioteck of 1973 of a copy with manuscript markings. A reason for revisiting this pamphlet is that the National Library of Scotland has graciously given permission to reproduce a copy (shelfmark NE.10.e.4) featuring a preface and significant markings in manuscript not in the copy that Price reproduced in his book. As Hume assumes considerable familiarity with the events to which he alludes, we have annotated the text to make it fully intelligible to readers two and half centuries after its composition. The rudimentary bibliographic facts and mysteries are as follows. Two editions survive to us, an octavo (in fours) and a rare duodecimo. Although there is no reason to regard the duodecimo as a second edition correcting or augmenting a first edition, it probably was manufactured after, and was textually derivative from, the octavo. We know nothing of the publishing of M. A. Box is Associate Professor of English, University of Alaska, Fairbanks, PO Box 755720, Fairbanks, AK 99775-5720, USA. David Harvey is at the Classics Department, University of Exeter, Queen's Building, Queen's Drive, Exeter EX4 4QH, UK.

Box, David Harvey, and Michael Silverthorne the duodecimo, and doubtless that is as its producers intended. Its title page indicates, like that of the octavo, that the printing was done "for M. Cooper" in 1748, but William Strahan's ledgers register the printing in December 1747 of only the octavo in an edition of 1000 copies.1 The job is listed under bookseller Andrew Millar's account, not Mary Cooper's, probably for the reason that Cooper was a front whose role was to screen the true producers. It is possible that Millar hired someone other than Strahan to print the duodecimo, but it is also possible that someone other than Millar had it printed to mimic the octavo and take the opportunity it offered for concealment.2 A different editorial judgment is evinced in the duodecimo in that cosmetic measures are taken in it to obscure the identities of two military men ridiculed. For example, "Fowke" is rendered as "F—" and "John Cope" as "J-C-----." A digression on Mary Cooper is in order. This remarkable woman (died 1761) took over her husband Thomas's business upon his death 9 February 1743. That business had a history of "publishing" pamphlets and therefore made a plausible front for Millar, who in at least thirty-six other instances, none requiring courage, was willing to have his name appear on a title page with "M. Cooper." (This figure derives from a search by imprints using the English Short-Title Catalogue.) Until Thomas Cooper died, his name appeared on editions of John Armstrong's The Oeconomy of Love (1736 and thereafter) though only Millar's name is listed in the Stationers' Register (Foxon, English Verse A303-A311), and Mary's name is on the title page of the 1753 edition for which Strahan charged Millar (Strahan Papers, Add. MS 48800, s.v. August 1753). It was perhaps in this pattern that the second edition of Hume's heterodox Philosophical Essays (1750) would be reissued in 1751 with a new title page replacing Millar's name with Cooper's. That book was made temporarily a more alarming property by the superstitious panic of the London populace following the winter earthquakes in 1750, presaged by a bloody cloud. Within that year Bishop Thomas Sherlock caused a stir with a pastoral letter (A Letter from the Lord Bishop of London) blaming the earthquakes on several iniquities, "particularly heretical books" (Walpole, Correspondence 20...

The article discusses poet Oliver Goldsmith's remarks, which illustrates philosopher and historian, David Hume's contemporary reputation. Goldsmith lamented, however, that the praise due to literary merit is already occupied by the first writers, who will keep it and get the better even of the superior merit which the moderns may possess. He said David Hume was one of those, who, seeing the first place occupied on the right side, rather than take a second, wants to have a first in what (...) is wrong. (shrink)

Philosophical naturalism faces a dilemma: take it as an ideology, and you face charges of internal incoherence, since the ideological stance itself does not look to be a deliverance of science. Forgo the ideological aspect, on the other hand, and naturalism becomes a merely subjective assessment, a cry of “yay for science!” that carries no normative weight for those who are not inclined to agree. I first argue that both horns of this dilemma are sharp, and that current attempts to (...) negotiate them have failed. I then give a plausible construal of methodological naturalism that is both ideological and internally coherent, and so threads this dilemma. Finally, I consider objections to this formulation of naturalism. (shrink)

To carry on reasoning in the face of the implications of skepticism is what Fred Parker calls “sceptical thinking.” Not to be confused with the engineered vacillation leading to a tranquillizing suspense of judgement, it involves the double perspective of someone conducting a life, believing and reasoning as we do, while acutely aware that the whole endeavor is, in a sense, untenable. If, as Sir Philip Sidney famously said, an imaginative writer “nothing affirms, and therefore never lieth,” then the dilemma (...) posed by skepticism might be less embarrassing for that kind of writer than for philosophers. The latter purport to offer tenets valued according to their truth, however variously defined; the former, on the other hand, create “speaking pictures,” or verbal imitations. Skeptically thinking imaginative writers can create speaking pictures of a life in which knowledge is unavailable though people must reason, believe, and act. In a famous letter Keats went so far as to deem a kind of ataraxy to be a condition of the highest art, adducing Shakespeare’s “Negative Capability... of being in uncertainties, Mysteries, doubts, without any irritable reaching after fact & reason”. Parker does not discuss the possibility that negative capability might conduce to the highest flights of literature. He is concerned with the unresolved tensions of skeptical thinking that he sees as complicating key works of literature in the Hanoverian reigns. For their authors and readers, the negativity of skepticism was “disillusioning and destabilizing” if not ameliorated by a humor like Sterne’s or an irony like Hume’s. Humor or irony arises from the oddity that skepticism is put in its place only when we give up and allow nature to reassert itself. Not heroic measures, but backgammon and making merry with friends prevail over doubt. Sometimes, when the confrontation with skepticism gives rise to the precept of following nature, skepticism can result in “a surprising confidence of assertion”. (shrink)

The aim of this article is to analyze the meaning of the concept of empire during the first years of the Francoist regime and try to clarify the different meanings that the various political and ideological groups that were part of the dictatorship gave to this concept. As will be explained, it is possible to find two main meanings for the concept of empire . The first one was linked to the notion of Hispanidad and was developed by the Catholic (...) and counter-revolutionary groups; in this case, empire was defined through the Catholic religion and the missionary role that Spain had played in the discovery of America, the moment that marked the beginning of the Spanish Empire. The second meaning was developed inside the Falangist party. It contained fascist values and was linked to an ideal of expansionism that would support specific policies. The aim here is to differentiate these meanings by paying attention to the different contexts in which they were produced. (shrink)

The article focuses on the book "Essays, Moral and Political," by David Hume. In this book Hume quoted, but did not identify, two Hudibrastic couplets. He altered them so as to make them grammatically continuous with his prose, but not so much that a polite reader of his day would fail to recognize them.

In order to explore whether and how Jewish teachings influence the attitudes of strictly-orthodox Jews to clinical trials, 10 strictly-orthodox Jews were purposively selected and interviewed, using a semi-structured schedule. Relevant literature was searched for similar studies and for publications covering relevant Jewish teachings. Thematic analysis was used to analyse transcribed interviews and explore relationships between attitudes and Jewish teachings identified in the review. Participants’ attitudes were influenced in a variety of ways: by Jewish teachings on the over-riding importance of (...) preserving life—the need to avoid risks affecting life and health, while taking risks to preserve life—and the religious obligation to help others, as well as by previous experience. Attitudes mirrored those in the general population, enabling many participants to reach conclusions that did not differ materially from those of the general population or research ethics committees.
