Relaxed realist theories are becoming more common in metanormative theory. They want the advantages of robust forms of realism but without their metaphysical underpinnings. However, it is not always clear how we should understand relaxed realist theories in general. In this paper I clarify and defend relaxed realism. First, I characterise and distinguish relaxed realist theories from robust realist theories. Second, I defend relaxed realism against a challenge from truthmaker theory.

This study fills an important gap in the literature by providing causal evidence of the impact of relaxing financial constraints on corporate social responsibility (CSR). To isolate this causal link, we examine the enactment of anti-recharacterization laws in some U.S. states, an exogenous shock that has strengthened creditor rights and eased financial constraints of the treated firms. Our difference-in-difference analysis suggests that relaxing financial constraints leads to higher CSR. This evidence is more pronounced in financially constrained firms, firms with more (...) analyst dispersion and increased volatility of cash flows. We also find that the most impacted firms are those with increased post-shock debt financing. In sum, our evidence suggests that easing access to external finance drives corporate goodness, in particular in firms that value external financing. (shrink)

As with all other moral realists, so-called relaxed moral realists believe that there are moral truths. Unlike metaphysical moral realists, they do not take themselves to be defending a substantively metaphysical position when espousing this view, but to be putting forward a moral thesis from within moral discourse. In this paper, I employ minimalism about truth to examine whether or not there is a semantic analysis of the claim ‘There are moral truths’ which can support this moral interpretation of one (...) of moral realism’s key theses. My results are both discouraging and encouraging: Whilst I will argue that the claim ‘There are moral truths’ cannot be shown to be both moral and capable of demarcating relaxed realism from irrealism on the basis of a convincing semantic analysis that would be compatible with relaxed commitments, the moral interpretation of moral realism can be secured by modifying our understanding of what distinguishes relaxed realism from error-theoretic irrealism. Yet, we will see that this moral interpretation of moral realism does not ‘tumble out’ of the semantics provided for its central claims. Rather, hard work needs to be done before we can fully relax.

Nelson’s stochastic quantum mechanics provides an ideal arena to test how the Born rule is established from an initial probability distribution that is not identical to the square modulus of the wavefunction. Here, we investigate numerically this problem for three relevant cases: a double-slit interference setup, a harmonic oscillator, and a quantum particle in a uniform gravitational field. For all cases, Nelson’s stochastic trajectories are initially localized at a definite position, thereby violating the Born rule. For the double slit and (...) harmonic oscillator, typical quantum phenomena, such as interferences, always occur well after the establishment of the Born rule. In contrast, for the case of quantum particles free-falling in the gravity field of the Earth, an interference pattern is observed before the completion of the quantum relaxation. This finding may pave the way to experiments able to discriminate standard quantum mechanics, where the Born rule is always satisfied, from Nelson’s theory, for which an early subquantum dynamics may be present before full quantum relaxation has occurred. Although the mechanism through which a quantum particle might violate the Born rule remains unknown to date, we speculate that this may occur during fundamental processes, such as beta decay or particle-antiparticle pair production.

The ethical question is whether university mask mandates should be relaxed. I argue that the use of face masks by healthy individuals has uncertain benefits, which potential harms may outweigh, and should therefore be voluntary. Systematic reviews by the World Health Organization (WHO) and Cochrane Acute Respiratory Infections concluded that the use of face masks by healthy individuals in the community lacks effectiveness in reducing viral transmission based on moderate-quality evidence. The only two randomized controlled trials of face masks published (...) during the pandemic found little to no benefit. Without high-quality evidence, it is difficult to justify a requirement rather than a recommendation. Notwithstanding, one might argue that the precautionary principle justifies mask mandates. If the precautionary principle can justify implementing mask mandates due to the risk of forgoing possible benefit, then it might also be able to justify not implementing mask mandates due to the risk of potential harm caused by the intervention. It is commonly thought that there is little to lose from the use of face masks, but this is not necessarily true. It is possible that masks have done more harm than good. (shrink)

Relaxed realists hold that there are deep differences between moral truths and the truths studied by the empirical sciences, but they deny that these differences raise troubling metaphysical or epistemological questions about moral truths. On this view, although features such as causal inefficacy, perceptual inaccessibility, and failure to figure in the best explanations of our empirical beliefs would raise pressing skeptical concerns were they claimed to characterize some aspect of physical reality, the same is not true when it comes to (...) the moral domain. This chapter raises some doubts about this general picture of morality and some prominent ways of defending it. First, it takes up a comparison that is frequently invoked by relaxed realists, and one on which they often place a great deal of weight: a comparison between irreducibly normative properties and truths on the one hand, and mathematical properties and truths on the other. It argues that this comparison is much less favorable to the relaxed realist’s cause than is often thought. It then offers an extended critique of a particularly vigorous and sustained presentation of relaxed realism: that offered by Ronald Dworkin in Justice for Hedgehogs. (shrink)

In this paper I argue that relaxed realism can answer questions about normative language and thought without collapsing into one of the familiar views in the literature or becoming implausible. More specifically, contrary to Michael Ridge, I argue that relaxed realists can use an inferentialist approach to metasemantics without their view collapsing into naturalism or quasi-realism. The inferentialist account that I propose is that the role of normative expressions involves language-entry transitions construed as rational intuitions and language-exit transitions explained in (...) terms of rational agency. I argue that this account fits with relaxed realism and keeps the view distinct from naturalism, quasi-realism, and other familiar views in the literature. (shrink)

In this paper I argue that so-called “Relaxed Realism” of the sort defended by T. M. Scanlon fails on its own terms by failing to distinguish itself from its putative rivals—in particular, from Quasi-Realism. On a whole host of questions, Relaxed Realism and Quasi-Realism give exactly the same answers, and these answers make up much of the core of the view. Scanlon offers three possible points of contrast, each of which I argue is not fit for purpose. Along the way (...) I argue that Quasi-Realists can provide a better account of practical rationality than Relaxed Realists can, so insofar as they are distinct Quasi-Realism is superior. (shrink)

I offer an account of normative belief designed specifically for relaxed realists. This proposal not only gives relaxed realists an explicitly robust account of normative belief but also distinguishes their theory from related theories, notably quasi-realist ones. In doing so, it addresses a dilemma raised in the literature against relaxed realist theories.

Can our caring about truth be rooted in “relaxed” naturalism? I argue that it cannot. In order to care about truth we need the universe to be capable of providing non-adventitious good, which relaxed naturalism cannot do. I use Michael Lynch’s work as a springboard to showing this claim.

An esteemed modern Tibetan Buddhist teacher presents a system of meditation instructions designed for achieving relaxation in our stressful, fast-paced world In the late 1990s, shortly after arriving in the United States, it became clear to Dza Kilung Rinpoche that his Western students responded to traditional meditation instructions differently from his students back in Asia. The Westerners didn't know how to relax—and their pressured, fast-paced lifestyles carried over into meditation. With this in mind, Dza Kilung Rinpoche set out to (...) create a meditation system that could break through the noise of Western life. The Relaxed Mind contains instructions for the seven-phase practice that he developed for students in the West. It is adapted from traditional instructions to counteract the overwhelming distraction that is becoming a global culture these days, not only in the West. Beginners will find a wealth of useful, easy-to-understand information while more experienced meditators may be surprised to find their practice deepening through letting go of tension. (shrink)

Ludwig Wittgenstein has often been called a quietist. His work has inspired a rich and varied array of theories in moral philosophy. Some prominent meta-ethicists have also been called quietists, or ‘relaxed’ as opposed to ‘robust’ realists, sometimes with explicit reference to Wittgenstein in attempts to clarify their views. In this chapter, I compare and contrast these groups of theories and draw out their importance for contemporary meta-ethical debate. They represent countercultures to contemporary meta-ethics. That is, they reject in different (...) ways one or more of the common assumptions that, whilst not universally shared, shape how to understand and engage in contemporary meta-ethical debate. Despite striking similarities, I argue that the ‘quietist’ label has obscured the views it is used to describe, the crucial differences between them, and the challenge that they offer to the predominant culture of meta-ethical enquiry. That challenge is this: there are plausible different ways of understanding and doing meta-ethics to those of the meta-ethical orthodoxy. We ignore such heterodoxy at our own peril. (shrink)

In this paper, I develop a metasemantics for relaxed moral realism. More precisely, I argue that relaxed realists should be inferentialists about meaning and explain that the role of evaluative moral vocabulary is to organise and structure language exit transitions, much as the role of theoretical vocabulary is to organise and structure language entry transitions.

This thesis is concerned with a relaxed form of normative realism. Relaxed realists accept the existence of mind-independent normative truths, properties, and facts, but argue that normative truths do not have truthmakers and that normative properties and facts are not metaphysically robust. The thesis develops relaxed realism by responding to various objections and challenges. The first paper argues that relaxed realists can answer questions about normative language without their theory collapsing into one of the familiar theories in the literature or (...) becoming implausible. More specifically, contrary to Michael Ridge (2019), it argues that relaxed realists can embrace an inferentialist account of normative terms without their theory collapsing into naturalism or quasi-realism. The second paper offers an account of normative belief specifically designed for relaxed realists. It argues that relaxed realists can explain normative belief through a functionalist theory of mind. This proposal not only provides relaxed realists with an explicit explanation of normative belief but also distinguishes it from related theories, notably quasi-realist theories. In doing so, it addresses a previously unresolved dilemma raised by Ridge (2019) and Böddeling (2020) concerning the relaxed realist’s view of normative belief. The third paper clarifies and defends relaxed realism. It justifies the claim that normative truths do not have truthmakers by arguing that these truths are true not because of the existence of truthmaking entities but simply because of the way things are normatively. The fourth paper examines the kind of relaxed realist theory that Scanlon (2014) defends within a “domain-centered view” of existence and truth. The article highlights how this view makes relaxed realism more viable by defending it against objections based on substantive domain-independent ideas, such as the idea that all (synthetic) truths must have truthmakers. Additionally, it presents a distinct argument, different from the one presented in the third paper, to justify the claim that normative truths do not have truthmakers. (shrink)

This paper attempts to relax the tension between Adam Smith's claim that sympathy involves an evaluative act of imaginative projection and his claim that sympathy involves a non-evaluative act of imaginative identification. The first section locates the tension specifically in the two different ways Smith depicts the stance adopted by the sympathizer. The second section argues that we can relax this tension by finding an important role for a non-evaluative stance in Smith's normative account of moral evaluation. This solution protects (...) the continuity in Smith's account of sympathy (cf. Griswold 1999: 99–103). Because of the particular way in which it renders intelligible the relationship between the evaluative and non-evaluative stances, this solution also emphasizes the importance that respect for the agent's conscience has in Smith's conception of an ideal moral judge (cf. Darwall 2004; 2006). The third section investigates a possible systematic basis for Smith's normative commitment to respectful moral judgment. (shrink)

IntroductionAn individual’s level of mindfulness can predict his/her level of general health, anxiety, and anger. If we have a valuable tool for measuring mindfulness, we can predict such factors more concisely. Therefore, the aim of this study was to compare a narrowband and a broadband mindfulness scale in predicting the level of general health, anxiety, and anger in a general population.Materials and MethodsThis was a cross-sectional study on an Iranian general population from September 22, 2020 to April 14, 2021. The (...) convenience sampling method was used. Data were collated via electronic and paper forms of the Relaxation/Meditation/Mindfulness Tracker t-Persian version, the Freiburg Mindfulness Inventory- Short-Form-Persian version, the General Health Questionnaire, the trait anxiety section of the State–Trait Anxiety Inventory, and the trait anger section of the State–Trait Anger Expression Inventory-2.ResultsThe FMI-P predicted 0.05% of GHQ variance while the first and third levels of RMMt-P predicted 0.145%. The FMI-P predicted 0.19% of anxiety variance, while the first and third levels of RMMt-P predicted 0.195%. The FMI-P predicted 0.0% of anger variance, while the first, second, and third levels of RMMt-P predicted 0.08%. RMMt-P Level 1 was a better predictor of general health, anger, and anxiety.ConclusionThe current study found that the RMMt-P was a better predictor of general health and anger than the FMI-P. These findings suggest that the type of questionnaire used in the study of mindfulness is important, but more research is needed to determine the extent of these relationships. (shrink)

Robust Realists think that there are irreducible, non-natural, and mind-independent moral properties. Quasi-Realists and Relaxed Realists think the same, but interpret these commitments differently. Robust Realists interpret them as metaphysical commitments, to be defended by metaphysical argument. Quasi-Realists and Relaxed Realists say that they can only be interpreted as moral commitments. These theories thus pose a serious threat to Robust Realism, for they apparently undermine the very possibility of articulating the robust metaphysical commitments of this theory. I clarify and respond (...) to this threat, showing that there is in fact space to develop and defend a robust moral ontology. (shrink)

The generation of complex organ structures such as the eye requires the intricate orchestration of multiple cellular interactions. In this paper, early retinal development is discussed with respect to the structure formation of the optic cup. Although recent studies have elucidated molecular mechanisms of retinal differentiation, little is known about how the unique shape of the optic cup is determined. A recent report has demonstrated that optic‐cup morphogenesis spontaneously occurs in three‐dimensional stem‐cell culture without external forces, indicating a latent intrinsic (...) order to generate the structure. Based on this self‐organizing phenomenon, we introduce the “relaxation‐expansion” model to mechanically interpret the tissue dynamics that enable the spontaneous invagination of the neural retina. This model involves three consecutive local rules (relaxation, apical constriction, and expansion), and its computer simulation recapitulates the optic‐cup morphogenesis in silico. (shrink)

Relaxed naturalism and liberal naturalism both invite us to adopt a philosophy of nature that includes a range of non-scientific phenomena in its inventory while nevertheless keeping the supernatural at bay. This paper considers the question of how relaxed naturalism relates to liberal naturalism and what refinements are required if they are to succeed in their joint cause of developing a tenable alternative to scientific naturalism. Particular attention is given to what might be added to the naturalist’s toolbox when it (...) comes to identifying and dealing with supernatural excesses and clarifying how philosophers can do positive metaphysical work in support of the naturalistic project.

While game theory has been transformative for decision making, the assumptions made can be overly restrictive in certain instances. In this work, we investigate some of the underlying assumptions of rationality, such as mutual consistency and best response, and consider ways to relax these assumptions using concepts from level-k reasoning and quantal response equilibrium (QRE) respectively. Specifically, we propose an information-theoretic two-parameter model called the quantal hierarchy model, which can relax both mutual consistency and best response while still approximating level-k, (...) QRE, or typical Nash equilibrium behavior in the limiting cases. The model is based on a recursive form of the variational free energy principle, representing higher-order reasoning as (pseudo) sequential decision-making in extensive-form game tree. This representation enables us to treat simultaneous games in a similar manner to sequential games, where reasoning resources deplete throughout the game-tree. Bounds in player processing abilities are captured as information costs, where future branches of reasoning are discounted, implying a hierarchy of players where lower-level players have fewer processing resources. We demonstrate the effectiveness of the quantal hierarchy model in several canonical economic games, both simultaneous and sequential, using out-of-sample modelling. (shrink)

In his new book Unbelievable Errors, Bart Streumer argues that there is no way around the result that all metaethical views other than the error theory either fail for the same reasons as metaphysical normative realism, or for the same reasons as expressivism. In this contribution, I seek to show that this is false: We can eschew this result by ‘relaxing’ about normative truths. Even if Streumer were right about the fate of metaphysical normative realism and expressivism, then, relaxed realists (...) can avoid the problems he raises. (shrink)

Transcription and DNA supercoiling are known to be linked by a cause‐effect relationship that operates in both directions. It is proposed here that this two‐way relationship may be exploited by the E. coli genome to facilitate constitutive transcription of supercoil‐sensitive genes by polymerase batteries made up of uniformly spaced RNA polymerase elongation complexes. Specifically, it is argued that (1) polymerases transcribing DNA in tandem cooperate to relax each other's transcription‐driven positive supercoils; and (2) negative supercoils driven upstream by elongation complexes (...) tend to be ‘harnessed’ and used to cooperatively (and periodically) initiate fresh transcription from promoters. Harnessing of transcription‐driven negative supercoils is thought to be achieved through the erection of protein barriers to the rotational upstream propagation of supercoils from transcription events. The possible relevance of such cooperation amongst polymerases to the activation of transcription by DNA‐binding protein factors is emphasized. Some testable predictions are made and implications are discussed. (shrink)

When it comes to evaluating reductive hypotheses in metaphysics, supervenience arguments are the tools of the trade. Jaegwon Kim and Frank Jackson have argued, respectively, that strong and global supervenience are sufficient for reduction, and others have argued that supervenience theses stand in need of the kind of explanation that reductive hypotheses are particularly suited to provide. Simon Blackburn's arguments about what he claims are the specifically problematic features of the supervenience of the moral on the natural have also been (...) influential. But most discussions of these arguments have proceeded under the strong and restrictive assumptions of the S5 modal logic. In this paper we aim to remedy that defect, by illustrating in an accessible way what happens to these arguments under relaxed assumptions and why. The occasion is recent work by Ralph Wedgwood, who seeks to defend non-reductive accounts of moral and mental properties together with strong supervenience, but to evade both the arguments of Kim and Jackson and the explanatory challenge by accepting only the weaker, B, modal logic. In addition to drawing general lessons about what happens to supervenience arguments under relaxed assumptions, our goal is therefore to shed some light on both the virtues and costs of Wedgwood's proposal.

Jay Rosenberg introduces Immanuel Kant's masterwork, the Critique of Pure Reason, from a "relaxed" problem-oriented perspective which treats Kant as an especially insightful practicing philosopher, from whom we still have much to learn, intelligently and creatively responding to significant questions that transcend his work's historical setting. Rosenberg's main project is to command a clear view of how Kant understands various perennial problems, how he attempts to resolve them, and to what extent he succeeds. At the same time the book is (...) an introduction to the challenges of reading the text of Kant's work and, to that end, selectively adopts a more rigorous historical and exegetical stance. Accessing Kant will be an invaluable resource for advanced students and for any scholar seeking Rosenberg's own distinctive insights into Kant's work. (shrink)

This study aims to investigate whether simple and convenient progressive relaxation training is effective in enhancing collegiate student athletes’ mental health and sports performance. An experimental group of 14 and a control group of 10 collegiate student athletes were recruited from among track and field athletes who were preparing for provincial competition. The experimental group was exposed to a PRT intervention in 30-min sessions conducted twice per week for a duration of one month. At baseline, the Competitive State Anxiety (...) Inventory-2, State-Trait Anxiety Inventory, and Eysenck Personality Questionnaire-Revised Short Scale for Chinese were completed, while only the CSAI-2 was reassessed at one, two, and three weeks after initiation of the intervention. Additionally, within half a day after completing all one’s individual competition events, the CSAI-2 was again assessed in the two groups recalling their memory of their precompetition state anxiety. Then, the differences in the three dimensions of the CSAI-2 between the two groups at the five time points introduced above were compared. This study also explored whether PRT affected sports performance, defined by the athletes reaching their best records or not, by logistic regressive analysis. This study found significant between-group differences in the self-confidence dimension score at the second and third time points. Through logistic regression analysis, a positive effect of PRT was found for the enhancement of sports performance. In sum, PRT showed positive effects on precompetition state self-confidence and enhanced sports performance among collegiate student athletes. (shrink)

Growing evidence suggests that natural environments – whether in outdoor or indoor settings – foster psychological health and physiological relaxation, indicated by increased wellbeing, reduced stress levels, and increased parasympathetic activity. Greater insight into differential psychological aspects modulating psychophysiological responses to nature-based relaxation videos could help understand modes of action and develop personalized relaxation interventions. We investigated heart rate variability as an indicator of autonomic regulation, specifically parasympathetic activity, in response to a 10-min video intervention in two (...) consecutive studies as well as heart rate. We hypothesized that a nature-based relaxation video elicits HRV increase and HR decrease, with response magnitude being affected by aspects of early life adversity and trait mindfulness. In Study 1, N = 60 participants watched a relaxation video intervention depicting different natural scenery. We analyzed changes in HR and respiratory sinus arrhythmia as a standard HRV measure, both based on 3-min segments from the experimental session, in multiple growth curve models. We found a decrease in HR and increase of RSA during the video intervention. Higher paternal care and lower trait mindfulness observing skills were associated with higher RSA values before but not during video exposure. In Study 2, N = 90 participants were assigned to three video conditions: natural scenery from Study 1, meditation video, or short clip from “The Lord of the Rings.” Again, HR decreased, and RSA increased during video segments, yet without expected group differences across different video types. We found higher parental care and lower parental overprotection to predict higher RSA at different times during the experiment. Interestingly, lower paternal overprotection predicted overall higher RSA. These results suggest a generic relaxation effect of video interventions on autonomic regulation that we discuss in light of different theories mapping restorative effects of natural environments. Further, psychological characteristics like aspects of early life adversity and trait mindfulness could contribute to individual differences in autonomic regulation. This study contributes to a better understanding of autonomic and psychological responses to relaxation videos. (shrink)

Among contemporary liberal political theorists in the West, there appears to be a standoff between two camps. One camp promotes tighter social bonds through collective responsibility and patriotic fellow-feeling while the other insists on the need for relaxed social bonds through respect for individual freedom. This essay shows how two Vietnamese thinkers—Ho Chi Minh (1872–1969) and Nguyen Manh Tuong (1909–1997)—can help move this intractable debate about collective responsibility and individual freedom beyond statements of principle to a more pragmatic discussion of (...) what should be done to maintain a healthy polity. They present an alternative to the static standoff, arguing that dynamic oscillation between two activities can forge national fraternal solidarity while also respecting individual freedom when the needs arise: ‘criticism and self-criticism' which tightens social bonds, and ‘liberal self-exploration' which relaxes social bonds.

This theoretical paper considers the morality of machine learning algorithms and systems in the light of the biases that ground their correctness. It begins by presenting biases not as a priori negative entities but as contingent external referents—often gathered in benchmarked repositories called ground-truth datasets—that define what needs to be learned and allow for performance measures. I then argue that ground-truth datasets and their concomitant practices—that fundamentally involve establishing biases to enable learning procedures—can be described by their respective morality, here (...) defined as the more or less accounted experience of hesitation when faced with what pragmatist philosopher William James called “genuine options”—that is, choices to be made in the heat of the moment that engage different possible futures. I then stress three constitutive dimensions of this pragmatist morality, as far as ground-truthing practices are concerned: the definition of the problem to be solved, the identification of the data to be collected and set up, and the qualification of the targets to be learned. I finally suggest that this three-dimensional conceptual space can be used to map machine learning algorithmic projects in terms of the morality of their respective and constitutive ground-truthing practices. Such techno-moral graphs may, in turn, serve as equipment for greater governance of machine learning algorithms and systems. (shrink)

Harm-reduction approaches are used to reduce the burden of risky human behaviour without necessarily aiming to stop the behaviour. We discuss what an introduction of harm reduction for doping in sports would mean in parallel with a relaxation of the antidoping rule. We analyse what is ethically at stake in the following five levels: (1) What would it mean for the athlete (the self)? (2) How would it impact other athletes (the other)? (3) How would it affect the phenomenon (...) of sport as a game and its fair play basis (the play)? (4) What would be the consequences for the spectator and the role of sports in society (the display)? and (5) What would it mean for what some consider as essential to being human (humanity)? For each level, we present arguments for and against doping and then discuss what a harm-reduction approach, within a dynamic regime of a partially relaxed antidoping rule, could imply. We find that a harm-reduction approach is morally defensible and potentially provides a viable escape out of the impasse resulting from the impossibility of attaining the eradication of doping. The following question remains to be answered: Would a more relaxed position, when combined with harm-reduction measures, indeed have less negative consequences for society than today9s all-out antidoping efforts that aim for abstinence? We provide an outline of an alternative policy, allowing a cautious step-wise change to answer this question and then discuss the ethical aspects of such a policy change. (shrink)

One of the claims sometimes advanced in favour of anti-doping is that allowing doping would lead to a uniform increase in performance in comparison to no doping. The idea is that if all athletes wo...

This contribution considers whether or not it is possible to devise a coherent form of external skepticism about the normative if we ‘relax’ about normative ontology by regarding claims about the existence of normative truths and properties themselves as normative. I answer this question in the positive: A coherent form of non-normative error-theories can be developed even against a relaxed background. However, this form no longer makes any reference to the alleged falsity of normative judgments, nor the non-existence of normative (...) properties. Instead, it concerns a specifically inferentialist construal of error-theories which suggests that error-theorists should abstain from any claims about normative ontology to focus exclusively on claims about the inferential role of normative vocabulary. As I will show, this suggestion affords a number of important advantages. However, it also comes at a cost, in that it might not only change the letter, but also the spirit of traditional error-theories. (shrink)

The aim of being able to reason about quantities, time or space has been the main objective of the many efforts on the integration of propositional planning with extensions to handle different theories. Planning modulo theories are an approximation inspired by satisfiability modulo theories that generalize the integration of arbitrary theories with propositional planning. Parallel plans are crucial to reduce plan lengths and hence the time needed to reach a feasible plan in many approaches. Parallelization of actions relies on the (...) notion of interference, which is usually determined syntactically at compile time. In this paper we define a semantic notion of interference between actions in PMT. Apart from being strictly stronger than any syntactic notion of interference, we show how semantic interference can be easily and efficiently checked by calling an off-the-shelf SMT solver at compile time, constituting a technique orthogonal to the solving method.

Embodiment theories have proposed a reciprocal relationship between emotional state and bodily reactions. Besides large body postures, recent studies have found emotions to affect rather subtle bodily expressions, such as slumped or upright sitting posture. This study investigated back muscle activity as an indication of an effect of positive and negative emotions on the sitting position. The electromyography activity of six back muscles was recorded in 31 healthy subjects during exposure to positive and negative affective pictures. A resting period was (...) used as a control condition. Increased muscle activity patterns in the back were found during the exposure to negative emotional stimuli, which was mainly measured in the lumbar and thorax regions. The positive emotion condition caused no elevated activity. The findings show that negative emotions lead to increased differential muscle activity in the back and thus corroborate those of previous research that emotion affects subtle bodily expressions.

In “Internalists Beware – We Might All Be Amoralists!” Gunnar Björnsson and Ragnar Francén Olinder [henceforth B&O] offer an original objection to motivational internalism, which promises to move the debate beyond the seeming stalemate between externalists and internalists. The main idea behind this objection is that to pose a challenge to internalists, amoralists need not fail to be motivated to do the right thing – they might reliably be motivated to do the right thing for the wrong reasons. Moreover, we (...) could all be amoralists if enough of us were motivated in this way – at any rate, this is an intelligible hypothesis. This, though, spells trouble for motivational internalism. The challenge is dialectically powerful precisely because internalists often fall back on the idea that although individuals can fail to be motivated to do what they take to be the right thing, the idea that whole communities could fail to be appropriately motivated yet still be making moral judgments makes no sense (Cf. Blackburn 1998: 61–63). The hypothesis put forward by B&O puts pressure on this classic internalist strategy of “going communal” by emphasizing that the assumption of no appropriate motivation is too stark; motivation of the wrong sort would still undermine internalism as it is best interpreted. In this paper, I argue that this intriguing new objection to internalism can, after all, be met if we pay special attention to judgments of blameworthiness. (shrink)

The quasiclassical theory in terms of Feynman path integrals is used to calculate the decay of the Cooperon amplitude caused by transverse gauge field fluctuations in a disordered electron system. It is found that the phase relaxation rate in two dimensions varies linearly with the temperature as in the more common case of electric field fluctuations, but is proportional to the conductance rather than the resistance. A logarithmic correction factor is found in comparison to an earlier qualitative estimate.
