Our sense of self includes awareness of our thoughts and movements, and our control over them. This feeling can be altered or lost in neuropsychiatric disorders as well as in phenomena such as “automatic writing” whereby writing is attributed to an external source. Here, we employed suggestion in highly hypnotically suggestible participants to model various experiences of automatic writing during a sentence completion task. Results showed that the induction of hypnosis, without additional suggestion, was associated with a small but significant (...) reduction of control, ownership, and awareness for writing. Targeted suggestions produced a double dissociation between thought and movement components of writing, for both feelings of control and ownership, and additionally, reduced awareness of writing. Overall, suggestion produced selective alterations in the control, ownership, and awareness of thought and motor components of writing, thus enabling key aspects of automatic writing, observed across different clinical and cultural settings, to be modelled.

Using Canada as a case study, this article argues that regulating biotechnology and nanotechnology is made unnecessarily complex and inherently unstable because of a failure to consult the public early and of-ten enough. Furthermore, it is argued that future regulators (and promoters) of nanotechnology may learn valuable lessons from the mistakes made in regulating biotechnology.

Sociologists of science and others have long been interested in how advances in science come about, and their potential social and economic impacts. Developments in nanoscience and nanotechnology will provide social scientists with a unique opportunity to explore how scientific activities form de novo. Additionally, scientists will have the opportunity to examine the factors that drive science and technology in certain directions by considering how different models of innovation may explain how the topography of the knowledge-based economy is being shaped (...) by radically new approaches to science.

Nature contact has associations with emotional ill-being and well-being. However, the mechanisms underlying these associations are not fully understood. We hypothesised that increased adaptive and decreased maladaptive emotion regulation strategies would be a pathway linking nature contact to ill-being and well-being. Using data from a survey of 600 U.S.-based adults administered online in 2022, we conducted structural equation modelling to test our hypotheses. We found that (1) frequency of nature contact was significantly associated with lesser emotional ill-being and greater emotional (...) well-being, (2) effective emotion regulation was significantly associated with lesser emotional ill-being and greater emotional well-being, and (3) the associations of higher frequency of nature contact with these benefits were partly explained via emotion regulation. Moreover, we found a nonlinear relationship for the associations of duration of nature contact with some outcomes, with a rise in benefits up to certain amounts of time, and a levelling off after these points. These findings support and extend previous work that demonstrates that the associations of nature contact with emotional ill-being and well-being may be partly explained by changes in emotion regulation.

Meditation refers to a family of self-regulation practices that focuses on training attention and awareness to foster psycho-emotional well-being and to develop specific capacities such as calmness, clarity, and concentration. We report a prospective convenience-controlled study in which we analyzed the effect of two components of Preksha Dhyāna – buzzing bee sound meditation and color meditation on healthy college students. Mahapran and leśya dhyāna are two Preksha Dhyāna practices that are based on sound and green color, respectively. The study population (...) represents a suitable target as college students experience different stress factors during the school year. This study measures the individual and combined effects of two techniques, on short-term memory, attention, and affect, in novice meditators. We used a battery of cognitive, performance, and compared results with baseline and control values. We found improved cognition, especially attention, short-term memory, and affect in terms of positivity and reduced negativity. Overall, the two techniques produced variable benefits and subjects showed improved scores over baseline for short-term memory, cognitive function, and overall wellbeing. Further studies are required to understand underlying mechanisms for the observed differences between the two techniques and to elucidate mechanisms underlying the more pronounced and global benefits observed with the combined techniques. These results underscore a need to examine individual components of meditation practices in order to individualize treatment approaches for attention disorders in young adults.Clinical Trail Registration:ClinicalTrials.gov Identifier: NCT03779269.

Advances in biotechnology make possible the transition toward a carbohydrate-based economy. By modifying plants to sequester more carbon and survive on marginal lands, more cost-effective means for using biomass are explored. This article discusses how better use of biomass can reduce greenhouse gas emissions and poses questions about how this transition can occur.

At present there is an enormous discrepancy between our nanotechnological capabilities (particularly our nanobiotechnologies), our social wisdom, and consensus on how to apply them. To date, cost considerations have greatly constrained our application of nanotechnologies. However, novel advances in microsystem platform technologies are about to greatly diminish that economic constraint while developing new industries. Properly used in a solid legal and ethical framework, within an educated population, these advances will vastly enrich our quality of life without being intrusive. Improperly used, (...) these technologies could lead to a modern-day Luddism, social turmoil, or possibly even to emulating those societies described in the darkest of novels. These technologies must be developed in tandem with the social and legal frameworks needed to ensure that they improve both individuals and our society. To ensure that this occurs, we need to have the ethical, legal, scientific, and engineering experts working together and with the public. (shrink)

The impetus of this study is to gauge the nexus between economic policy uncertainty and financial innovation in Brazil, Russia, India, China, and South Africa nations for the period from 2004M1 to 2018M12. This study utilizes both the linear and non-linear autoregressive distributed lag models to evaluate the long-run and the short-run association between EPU and financial innovation; furthermore, the causal effects are investigated by following the non-Granger casualty framework. The results of long-run cointegration, i.e., the test statistics of modified (...) F-test, standard Wald test, and tBDM, reject the null hypothesis and establish the presence of the long-run association between EPU and financial innovation. Conversely, long-run asymmetry cointegration revealed the test statistics of FPSS, WPSS, and tBDM in non-linear estimation. Furthermore, both in the long run and short run, the Wald test results disclose asymmetric effects running from EPU to financial innovation. In regards to the asymmetric impact of EPU on financial innovation, this study documents that the positive and negative shocks in EPU are negatively linked with financial innovation in the long run but are insignificant for short-run effects. Besides, financial innovation measured by R&D investment exhibits a positive linkage with shocks in EPU, implying that uncertainty induces innovation in the economy. Referring to causality effects, this study divulges the feedback hypothesis, i.e., bidirectional causality prevails between EPU and financial innovation in all sample countries. (shrink)

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

It is perhaps no accident that one of the finest books to appear on Heidegger in any language should come to us from the East. Mehta’s book was first published in India. The present Harper & Row edition constitutes chapters I, VIII, IX and X of that volume, the chapters devoted to Being and Time in the original having been omitted. That decision can only be regretted because, if the chapters on Being and Time are of the same quality (...) as those here published, they should be made available to us. What we have in fact then is a study of the later Heidegger, preceded by an introductory analysis of Heidegger’s method and language. Mehta’s scholarship is exhaustive, his numerous and lengthy notes touching upon all the major sources in the literature. His interpretation is so incisive that it is no exaggeration to place this book along with the works of Poeggeler and Marx among the outstanding studies of Heidegger’s thought. There is a great need for a thorough and reliable treatment of the later Heidegger in a readable English and Mehta’s book fills the bill.—J. D. C. (shrink)

The paper examines a single, apparently simple argument for the existence of incompatibilities between the virtues as traits of character. This argument appeals not to empirical truths about human psychology or human nature but to the possibility of conflict between the exercise of different virtues in action. There are, for example, situations in which we can exercise the virtue of truthfulness only at the expense of not exercising the virtue of tact, as when we are asked a question to which (...) the straightforward answer will pain our questioner. The person who in these situations would give a straightforward answer possesses the virtue of truthfulness to a higher degree than the person who would respond more evasively, whereas the latter person possesses the virtue of tact to a higher degree than the former. But since the two responses are mutually exclusive, it follows that the degree to which we possess the virtue of truthfulness must, at least in some measure, correlate inversely with the degree to which we possess the virtue of tact. And similarly for many other pairs of virtues. My paper focusses on the two cardinal assumptions of this argument, viz., (i) that sometimes the exercise of one virtue can conflict with the exercise of another, and (ii) that the degree to which a person possesses a virtue correlates directly with the extent of its exercise, and defends both assumptions against a variety of objections which allege that, in different ways, they are insensitive to the complexity of the virtues.

In this paper I want to examine a view of the Darwinian theory of evolution which was put forward fairly recently by A. R. Manser. His approach is of interest not only in itself, but also because it may be expanded to raise some fundamental questions about the nature of the science of biology in general. I shall not consider these further implications here, but shall concentrate on an examination of his thesis in the context in which it is raised. (...) My paper falls into two sections. In the first I shall state Manser's thesis and some of the arguments with which he supports it, and shall try to show how a series of objections raised by A. G. N. Flew and K. Connolly may be answered. In the second I shall offer on my own account a positive argument to provide a possible basis for his point of view, with the aim of indicating why the theory should be of the kind he suggests, and what form the study of evolution must take.

At the risk of proving myself such a caviller, I want to ask a question which I have seldom heard raised, and which I have never seen discussed in anything that I have read about Berkeley. If I am right, it poses a problem for his immaterialism, not only different, but coming from a different direction, from those objections that are commonly levelled against him. If I am wrong, it will show how right Berkeley was to stress the difficulty of (...) using for one purpose our language which has become fashioned for another. At least, I hope that I shall not fail to be the ‘fair and ingenuous reader’for whom he asked. (shrink)

The author has recently shown that a mathematical question regarding the fundamental constituents of hardrons cannot be resolved unless the classical axioms of nonfinite mathematics are revised in such a way as to produce a new theory of particle motion in continuous space-time. Under this new theory, the instantaneous position of a moving object has a magnitude that is increasing as the object's velocity. The purpose of this paper is to show that, quite apart from the question of Cantorian axiomatics, (...) the new theory of motion is more consistent with what physicists really believe than the traditional theory of motion.

In lieu of an abstract, here is a brief excerpt of the content:Humanism, Female Education, and Myth:Erasmus, Vives, and More's To CandidusA. D. CousinsWhen considering pleasure and chance as aspects of human experience, Thomas More sometimes gendered them female; that is to say, at times he represented them by drawing from the mythographies of Venus and of Fortune. But what did he suggest that actual women, as distinct from goddesses, were or should be or might become: what were his notions (...) of being a woman, of femaleness? Further, what did he suggest that women might contribute to the common weal? A useful way to start answering that question is to look at what More seems to have thought about educating women: in particular, women who were entering adult life—entering into what was agreed to be the major female role—by marrying for the first time and therefore newly taking upon themselves the management of a household. In one of his most ambitious Latin poems, as nowhere else, More wrote elaborately, concisely and problematically on the education of women who were in just those circumstances. My discussion attempts a repositioning of that poem, To Candidus: How to Choose A Wife A Poem in Iambic Dimeter Brachycatalectic (Versvs Iambici Dimetri Brachycatalectici ad Candidvm, Qvalis Vxor Deligenda). To make the attempt involves examining More's other Latin poems on women, as would be anticipated; however, I am mainly concerned here with affinities between To Candidus—then, to a lesser extent, some of More's associated Latin poems—and notions about female education that were or were to become part of the already long, and mostly male, debate about the nature of femaleness.1 To be [End Page 213] specific, I am chiefly concerned with affinities between More's poem and writings by Erasmus and by Vives on the education of prospective or of recent brides.Because the primary concern in my discussion is to clarify the relations between More's To Candidus and humanist notions on female education, especially notions put forward by two of More's humanist friends about young brides, I want initially to revisit the early modern debate on educating women, of course an important element of the wider debate about femaleness itself. One medieval and thence early modern idea on female education was that, in addition to what their mothers taught them, most women needed merely to receive religious and ethical instruction from their husbands, who would likewise instruct them in how to govern a household.2 After all, it was often pointed out, the household was women's natural domain: since, therefore, they would not normally engage with the world at large as would men—since, for example, they would not normally be educators, or writers, or politicians—women did not usually need the broad education appropriate to men.3 Assertion to the contrary was variously argued—and differences between or among those contrary assertions did not always depend on whether an author was male or female. In The Book of the City of Ladies (1405), a response to Boccaccio's De Mulieribus Claris and, perhaps unknowingly, also to Plutarch's The Virtues of Women, Christine de Pizan attempted to construct at once a refuge and a resource for [End Page 214] women, whom she recognized as having been misrepresented to themselves no less than to men throughout generations of misogynistic male fictions, ranging from satire to epic, from fable to history.4 Her City, in so far as it is a revisionist history of women, forms a textual space which does indeed offer a refuge as well as a resource, for Christine advocates that women, fulfilling their capabilities as women, aim at "cultivat[ing] virtue" and thereby gaining inclusion in the true, illustrious record of female achievement: membership of a textual community within which they will see themselves reflected and which is at one with the City of God.5 Inseparable from their seeking to do so, she emphasizes, will be their receiving education.6 Despite that emphasis—and despite her emphasizing that women are men's intellectual equals or, not infrequently, superiors—Christine nevertheless defends the concept that the domestic sphere and not the public is in general that "appropriate" to women.7...

The rules of formal logic favor the bootstrap over the fundamentalist interpretation of hadronic constituents.

The claims that Dr. F. H. George makes on behalf of his machines are obscurely stated. Does he claim that a machine has been made and has actually produced a kind of response which is incalculable, given the specification to which it has been built and also the prescribed conditions, what is put in for the particular performance in question? “Incalculable” does not mean that nobody has bothered to calculate, but that somebody has bothered, that the calculations show that the (...) response in question is not among the calculated ones, that it is not chance or mechanical breakdown, but a specific response to something specific among the given conditions. If he could substantiate this claim, then I would reluctantly agree that some machines are cleverer and more thoughtful than I thought possible, and some men sillier and less thoughtful, for they deliberately design machines to do they know not what.

Long term survival, as measured only by being alive, following inhouse cardiac arrest, is about (...) 15% over all age groups.2 In sick elderly patients over 70 years of age who survive a cardiac arrest, the subsequent hospital mortality approaches 100%.

Positivists have excelled at destructive criticism. This criticism has been useful for pruning away absurd and superfluous theories but it is liable to be used to prune away everything else. The latest exponents, the Logical Positivists, are no less adept at criticism than their predecessors. The doctrines of this school have been surrounded with an air of mystery and inquirers have been frightened off by alarming technical apparatus. We all know that the Logical Positivists had proved that everybody else talked (...) nonsense, but we did not know what they themselves talked. Mr. A. J. Ayer's exposition of the doctrine, Language, Truth and Logic , is therefore welcome as it is simple. (shrink)

There are many possible ways of approach to philosophy, and there is also an impossible one, though one that has often been tried. That the philosopher can somehow spin his philosophy out of what he finds inside himself; that he has some private internal source of information in virtue of which he can decide what the Universe must be, without needing to take the trouble to look at it, is a belief that dies hard. But it is now dying, if (...) not dead, so that it is hardly necessary to refute it in detail. It should suffice to say that anybody who cherishes the belief will not find anything to interest him in what follows. I shall simply assume that the philosopher is, what we all are to some extent, a spectator of the world and of man's life in it and a commentator on what he sees. Where the philosopher differs from others is in the kind of interest he takes in the facts, not in the kind of facts that are there to be interested in. (shrink)

Everybody is to some extent pacific, as everybody prefers to attain his ends by peaceful means if he can. Even the most bloodthirsty militarist uses threats of war rather than war, if threats will do the work. Though most people prefer persuasion to violence and peace to war, they are prepared as a last resort to go to war and use violence, when that seems the only means to attaining some end they consider to be of vital importance. The one (...) hundred per cent pacifist, however, refuses to engage in war or support warlike action under any circumstances whatever. It is his case that I wish to consider. It is not my purpose to try to persuade anyone to be a pacifist or to be the opposite, but to point out that absolute pacifism carries with it certain logical consequences which are not particularly palatable. The opposed view, which I shall call the case for civic virtues, also carries unpalatable though different consequences. These two appear to be simple and clear-cut opposed views which I propose to state as fairly as I can, with their consequences. Certain qualifications and modifications will have to be considered later, but I do not think that there is actually any possible mean position which avoids the dilemma I am concerned to present. I shall state the case for civic virtue first and the pacifist case second. (shrink)

Kedrov has reminded us that the development of knowledge proceeds from appearance to essence. That was also true of the development of notions about space and time. Leibniz, for example, defined space as the order of things existing at the same time. However, that definition is rather superficial, and it is only the development of physics, specifically relativity theory, which made it possible to penetrate more deeply into the nature of space and time and to ascribe a precise and mathematically (...) expressible notion to the well-known judgment to the effect that space and time are forms of the existence of matter.

Quantum anomalies in the inverse square potential are well known and widely investigated. Most prominent is the unbounded increase in oscillations of the particle’s state as it approaches the origin when the attractive coupling parameter is greater than the critical value of 1/4. Due to this unphysical divergence in oscillations, we are proposing that the interaction gets screened at short distances making the coupling parameter acquire an effective (renormalized) value that falls within the weak range 0–1/4. This prevents the oscillations (...) form growing without limit giving a lower bound to the energy spectrum and forcing the Hamiltonian of the system to be self-adjoint. Technically, this translates into a regularization scheme whereby the inverse square potential is replaced near the origin by another that has the same singularity but with a weak coupling strength. Here, we take the Eckart as the regularizing potential and obtain the corresponding solutions (discrete bound states and continuum scattering states). (shrink)
