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)

The Problem of Perception offers two arguments against direct realism--one concerning illusion, and one concerning hallucination--that no current theory of ...

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.

Disjunctivism is the focus of a lively debate spanning the philosophy of perception, epistemology, and the philosophy of action. Adrian Haddock and Fiona Macpherson present 17 specially written essays, which examine the different forms of disjunctivism and explore the connections between them.

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)

Unpopular in its day, David Hume's sprawling, three-volume 'A Treatise of Human Nature' (1739-40) has withstood the test of time and had enormous impact on subsequent philosophical thought. Hume's comprehensive effort to form an observationally grounded study of human nature employs John Locke's empiric principles to construct a theory of knowledge from which to evaluate metaphysical ideas. A key to modern studies of eighteenth-century Western philosophy, the Treatise considers numerous classic philosophical issues, including causation, existence, freedom and necessity, and morality.

Compares and contrasts the ethical systems derived from the major religions of the world.

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)
