What do we owe each other when we act together? According to normativists about collective action, necessarily something and potentially quite a bit. They contend that collective action inherently involves a special normative status amongst participants, which may, for example, involve mutual obligations to receive the concurrence of the others before leaving. We build on recent empirical work whose results lend plausibility to a normativist account by further investigating the specific package of mutual obligations associated with collective action according to (...) our everyday understanding. However, our results cast doubt on a proposed obligation to seek the permission of co-actors before exiting a collective action, and suggest instead that this obligation is a function of explicit promising. We then discuss how our results pave the path for a new normativism, a theory that neither under- nor overshoots the target given by our common conception of the interpersonal obligations present in collective action.*.

I review prominent historical arguments against scientific realism to indicate how they display a systematic overshooting in the conclusions drawn from the historical evidence. The root of the overshooting can be located in some critical, undue presuppositions regarding realism. I will highlight these presuppositions in connection with both Laudan’s ‘Old induction’ and Stanford’s New induction, and then delineate a minimal realist view that does without the problematic presuppositions.

In retrospecting "Two Dogmas" I find myself overshooting by twenty years. I think back to college days, 61 years agao. I majored in mathematics and was doing my honors reading in mathematical logic, a subject that had not yet penetrated the Oberlin curriculum. My new love, in the platonic sense, was Whitehead and Russell's Principia Mathematica.

The interventionist account of causal explanation, in the version presented by Jim Woodward, has been recently claimed capable of buttressing the widely felt—though poorly understood—hunch that high-level, relatively abstract explanations, of the sort provided by sciences like biology, psychology and economics, are in some cases explanatorily optimal. It is the aim of this paper to show that this is mistaken. Due to a lack of effective constraints on the causal variables at the heart of the interventionist causal-explanatory scheme, as presently (...) formulated it is either unable to prefer high-level explanations to low, or systematically overshoots, recommending explanations at so high of a level as to be virtually vacuous.

Longtermists have argued that humanity should significantly increase its efforts to prevent catastrophes like nuclear wars, pandemics, and AI disasters. But one prominent longtermist argument overshoots this conclusion: the argument also implies that humanity should reduce the risk of existential catastrophe even at extreme cost to the present generation. This overshoot means that democratic governments cannot use the longtermist argument to guide their catastrophe policy. In this paper, we show that the case for preventing catastrophe does not depend on (...) longtermism. Standard cost-benefit analysis implies that governments should spend much more on reducing catastrophic risk. We argue that a government catastrophe policy guided by cost-benefit analysis should be the goal of longtermists in the political sphere. This policy would be democratically acceptable, and it would reduce existential risk by almost as much as a strong longtermist policy. (shrink)

This article examines parallels between the increasing mental burnout and environmental overshoot in the organisational context. The article argues that there is a particular philosophy of management that connects these two phenomena of overshoot and burnout, namely productivism. As there are boundaries in all ecological processes and systems, the productivist aim of having ever more output and growth is deemed absurd. It is proposed that productivity as a management philosophy not only leads to mental ill-health in organisations but (...) also to overshoot in the environment. The article concludes that productivism, which denies the limits in utilisation of humans and other natural resources, fits poorly with circular economy and sustainability. Hence, ecological management should be complemented with a more holistic and processual view of organizations, as well as have an aim of peaceful coexistence between all earthbound objects. This signifies acknowledging and caring for human and non-human needs both now and in future by applying the idea of moderation to production of goods and services. (shrink)

Gilbertson et al should be commended for their insightful exploration of expanded terminal sedation (ETS)1; however, there are a number of concerns that I will address in this response. I will first better characterise the currently accepted and commonplace ‘standard’ TS (STS), and then argue that the advocated forms of ETS draw very close to—and at times clearly constitute a subtype of—euthanasia, as opposed to representing a similar but separate practice. I will then conclude with concerns regarding the inappropriate application (...) of ETS, particularly in the non-voluntary context. Gilbertson et al distinguish ‘gradual’ TS, which they state is the currently accepted form of TS, from ‘rapid’ TS, which is then argued to be a justifiable form of ETS. However, in my experience working in multiple large public teaching hospitals in New South Wales, Australia and consistent with local clinical practice guidelines,2 3 STS falls somewhere in the middle between ‘gradual’ and ‘rapid’ TS. STS explicitly aims to achieve permanent unconsciousness so as to eliminate the potential for (and therefore relieve) suffering; conversely, lighter or more intermittent forms of sedation, or administering sedatives with aims other than to achieve unconsciousness (eg, anxiolysis), do not constitute TS proper. STS uses doses proportionate to the extent of symptoms so as to avoid ‘overshooting’ and inadvertently administering excessive doses which actually hasten/cause death, in order to distinguish STS from euthanasia in this respect. This is achieved by gradually uptitrating doses when the patient appears distressed, and is therefore by definition …. (shrink)

This paper examines the idea of human rights, and how they should be justified. It begins by reviewing Peter Jones?s claim that the purpose of human rights is to allow people from different cultural backgrounds to live together as equals, and suggests that this by itself provides too slender a basis. Instead it proposes that human rights should be grounded on human needs. Three difficulties with this proposal are considered. The first is the problem of whether needs are sufficiently objective (...) for this purpose, to which it responds by drawing a distinction between human needs proper and societal needs. The second is the problem of overshoot: human needs are more expansive than human rights. It responds to this by arguing that where needs conflict, we make trade-offs before specifying the optimum set of human rights. The third is the problem of undershoot: needs cannot be used to ground civil and political rights. Here it suggests that some of these rights can be grounded directly in needs, others can be justified instrumentally, and yet others grounded in the human need for recognition. Finally the paper returns to Jones, and asks which approach to human rights is better able to justify them within both liberal and non-liberal cultures. (shrink)

Few issues in business ethics are as polarizing as the practice of risk classification and underwrit­ ing in the insurance industry. Theorists who approach the issue from a background in economics often start from the assumption that policy-holders should be charged a rate that reflects the ex­ pected loss that they bring to the insurance scheme. Yet theorists who approach the question from a background in philosophy or civil rights law often begin with a presumption against socalled “actuarially fair” premiums (...) and in favor of “community rating,” in which everyone is charged the same price. This paper begins by examining and rejecting the three primary argu­ ments that have been given to show that actuarially fair premiums are unjust. It then considers the two primary arguments that have been offered by those who wish to defend the practice of risk classification. These arguments overshoot their target, by requiring a “freedom to under­ write” that is much greater than the level of freedom enjoyed in most other commercial transac­ tions. The paper concludes by presenting a defense of a more limited right to underwrite, one that grants the legitimacy of the central principle of risk classification, but permits specific deviations from that ideal when other important social goods are at stake.

In this paper we argue that the protocols of subjects recalling the names of their high school classmates, as well as an army of traditional memory phenomena, can be understood from an information processing analysis which interprets retrieval as a problem‐solving process. This characterization of retrieval focuses on the reconstructive and recursive nature of the process of remembering. Retrieval is viewed as a process in which some information about a target item is used to construct a description of the item (...) and this description is used in attempts to recover new fragments of information. A new description i s formed and the process continues recursively. Three subprocesses are identified: FIND A CONTEXT, in which a proper environment for conducting a search i s established: SEARCH, in which bits and pieces of information appropriate to the context are recovered until an adequate description can be formed within the search context; and VERIFY, in which recovery information is checked for consistency.From the perspective this characterization, we examine the protocols of subjects asked to think aloud while recalling the names of their classmates. Subjects' retrievals continued for a surprisingly long period and were characterized by the phenomena of overshoot, systematic hypothesizing, fabrications, establishment of search contexts, self‐corrections, and the use of a number of basic search strategies. The view of memory as a problem‐solving process not only leads us to the identification of these phenomena but also to a framework for a coherent interpretation for them. (shrink)

The strongest arguments for the permissibility of geoengineering (also known as climate engineering) rely implicitly on non-ideal theory—roughly, the theory of justice as applied to situations of partial compliance with principles of ideal justice. In an ideally just world, such arguments acknowledge, humanity should not deploy geoengineering; but in our imperfect world, society may need to complement mitigation and adaptation with geoengineering to reduce injustices associated with anthropogenic climate change. We interpret research proponents’ arguments as an application of a particular (...) branch of non-ideal theory known as “clinical theory.” Clinical theory aims to identify politically feasible institutions or policies that would address existing (or impending) injustice without violating certain kinds of moral permissibility constraints. We argue for three implications of clinical theory: First, conditional on falling costs and feasibility, clinical theory provides strong support for some geoengineering techniques that aim to remove carbon dioxide from the atmosphere. Second, if some kinds of carbon dioxide removal technologies are supported by clinical theory, then clinical theory further supports using those technologies to enable “overshoot” scenarios in which developing countries exceed the cumulative emissions caps that would apply in ideal circumstances. Third, because of tensions between political feasibility and moral permissibility, clinical theory provides only weak support for geoengineering techniques that aim to manage incoming solar radiation.

In recent years, the notion of the body schema has been widely discussed, in particular in fields connecting philosophy, cognitive science, and dance studies, as it seems to have bearing across disciplines in a fruitful way. A main source in this literature is Shaun Gallagher’s distinction between the body schema – the “pre-noetic” conditions of bodily performance – and the body image – the body as intentional object –, another is Merleau-Ponty’s writings on the living body, that Gallagher often draws (...) upon. In this paper, I will first discuss Gallagher’s presumed clarification of body schema–body image, and discuss a recent critique by Saint Aubert (2013), who evaluates it against the backdrop of Merleau-Ponty’s thoughts on this issue. While I believe that Saint Aubert’s criticism overshoots the mark, it is useful for a clarification of Gallagher’s analysis and points to a problematic feature, namely the alleged inscrutability of the body schema to phenomenological reflection. This is particularly interesting in relation to contemporary dance and performance practice, where working with – and against – habitual structures is a core element. Certain contemporary training techniques are explicitly aimed at raising awareness of those bodily aspects that condition movement and expression – that Gallagher sees as pertaining to the body schema – and that in ordinary activities often remain hidden. In order to clarify the role that reflection on our own body and its habitual patterns plays in contemporary dance practice, I will examine the movement language and improvisation practice “Gaga”, where this aspect is arguably fundamental.

According to the standard opinions in the literature, blocking the unacceptable consequences of the notorious slingshot argument requires imposing constraints on the metaphysics of facts or on theories of definite descriptions (or class abstracts). This paper argues that both of these well-known strategies to rebut the slingshot overshoot the mark. The slingshot, first and foremost, raises the question as to the adequate logical formalization of statements about facts, i.e. of factual contexts. It will be shown that a rigorous application (...) of Quine’s maxim of shallow analysis to formalizations of factual contexts paves the way for an account of formalizing such contexts which blocks the slingshot without ramifications for theories of facts or definite descriptions.

Falling down a waterfall is a boundary experience that epitomizes a crisis. This philosophical essay draws an analogy to the maladaptation civilization finds itself in. Falling down a waterfall is a singular event, but it has structure. There are stages that lead up to it, and if one survives the fall, there will be stages that follow it. I suggest that such a mishap is analogous to the ecological overshoot. What leads to the overshoot, and what is entailed (...) by it, is a parallel sequence of stages. As a civilization, we are in an unprecedented situation: we have reached the limits of growth. We are overwhelming the load capacities of the global system, with climate change as tangible symptom. Akin to what leads up to a waterfall, the first stage of the civilizational crisis is a petering-out of familiar pathways. The second stage is reality-denial: the pretense that such petering-out cannot be happening. Stage three is the lure of the risky choice – followed by the great geopolitical freak-out, which is stage four, the core of the crisis. We’re in the current; we’re swept over the edge; we’re going down. And if we survive, the worst isn’t over yet, for now other dangers lurk. This is stage five: the stage of lethal irony. You think you’ve made it and win a Darwin Award anyway. But say you scrape by, then the final stage of the crisis will be a transition to lingering perils: an aftermath of heightened vulnerability.

Time is a fundamental dimension of consciousness. Many studies of the “sense of agency” have investigated whether we attribute actions to ourselves based on a conscious experience of intention occurring prior to action, or based on a reconstruction after the action itself has occurred. Here, we ask the same question about a lower level aspect of action experience, namely awareness of the detailed spatial form of a simple movement. Subjects reached for a target, which unpredictably jumped to the side on (...) some trials. Participants (1) expressed their expectancy of a target shift during the upcoming movement, (2) pointed at the target as quickly and accurately as possible before returning to the start posiment to the target shift if required and (3) reproduced the spatial path of the movement they had just made, as accurately as possible, to give an indication of their awareness of the pointing movement. We analysed the spatial disparity between the initial and the reproduced movements on those with a target shift. A negative disparity value, or undershoot, suggests that motor awareness merely reflects a sluggish record of coordinated motor performance, while a positive value, or overshoot, suggests that participants’ intention to point to the shifting target contributes more to their awareness of action than their actual pointing movement. Undershoot and overshoot thus measure the reconstructive (motoric) and the preconstuctive (intentional) aspects of action awareness, respectively. We found that trials on which subjects strongly expected a target shift showed greater overshoot and less undershoot than trials with lower expectancy. Conscious expectancy therefore strongly influences the experience of the detailed motor parameters of our actions. Further, a delay inserted either between the expectancy judgement and the pointing movement, or between the pointing movement and the reproduction of the movement, had no effect on visuomotor adjustment but strongly influenced action awareness. Delays during either interval boosted undershoots, suggesting increased reliance on a time-limited sensory memory for action. The experience of action is thus strongly influenced by prior thoughts and expectations, but only over a short time period. Thus, awareness of our actions is a dynamic and relatively flexible mixture of what we intend to do, and what our motor system actually does. (shrink)

In this paper, we designed and developed an intelligent tutoring system for teaching Photoshop. We designed the lessons, examples, and questions in a way to teach and evaluate student understanding of the material. Through the feedback provided by this tool, you can assess the student's understanding of the material, where there is a minimum overshoot questions stages, and if the student does not pass the level of questions he is asked to return the lesson and read it again. Eventually (...) this administration is a special teacher for the students and can continue with him until he fully understands the lesson without weariness or boredom, regardless of the level of student.

A less often remarked fact is that a work’s composition can overshoot its completion. It is the description apt for these cases that is the topic of this chapter. But before I get to that, it is useful to describe some of the signs that show a work to be finished.

This article argues that a main hidden driver of the Anthropocene is existential—namely the wholesale denial, in capitalist civilization, of human fragility and mortality. Mainstream economics, which unthinkingly validates the unboundedness of human wants and the necessity for open-ended growth, must give way to existential ecological economics—an approach that recognizes that capitalism, which clearly propels the overshoot of material flows, is itself a device for denying and repressing deep human fears about death.

Gliomas can display marked changes in the concentrations of energy metabolism molecules such as creatine (Cr), phosphocreatine (PCr) and lactate, as measured using magnetic resonance spectroscopy (MRS). Moreover, the BOLD (blood oxygen level dependent) contrast enhancement in functional magnetic resonance imaging (fMRI) can be reduced or missing within or near gliomas, while neural activity is not significantly reduced (so-called neurovascular decoupling), so that the location of functionally eloquent areas using fMRI can be erroneous. In this paper, we adapt a previously (...) developed model of the coupling between neural activation, energy metabolism and hemodynamics, by including the venous dilatation Balloon model of Buxton and Frank. We show that decreasing the cerebral blood flow (CBF) baseline value, or the CBF increase fraction, results in a decrease of the BOLD signal and an increase of the lactate peak during a sustained activation. Baseline lactate and PCr levels are not significantly affected by CBF baseline reduction, but are altered even by a moderate decrease of mitochondrial respiration. Decreasing the total Cr and PCr concentration reduces the BOLD signal after the initial overshoot. In conclusion, we suggest that the coupled use of BOLD fMRI and MRS could contribute to a better understanding of the neurovascular and metabolic decoupling in gliomas. (shrink)

Back and forth swings the pendulum. It is remarkable that Baars can claim that “many scientists now feel that radical behaviorists tossed out the baby with the bathwater” while not being able to see that his own efforts threaten to be an instance of the complementary overshooting–what we might call covering a nice clean baby with dualistic dirt . Yes indeed, radical behaviorism of Skinner’s variety fell from grace some years ago, with the so-called cognitive revolution, to be replaced by (...) a sort of cognitivistic behaviorism that has plenty of room for inner processes, for talking to yourself, for mental imagery, for hunches, feelings, pains, dreams, beliefs and hopes and expectations, but only so long as these are understood to be physical (“informational” or “computational”) processes that could be accomplished by the machinery of the brain. It is an interesting speculative question whether William James would have been a wholehearted cognitivist, or whether he would have insisted that what he meant by the stream of consciousness had to be sharply distinguished from the streams of mere information-manipulation discernible in the activities of cortical subsystems, etc., etc. Making a home for consciousness in the brain, for a distinction between unconscious information-transformations and conscious ones, for instance, is now the work of many hands in many fields (See, e.g., Dennett, 2001, and the other essays in the special issue of Cognition devoted to the cognitive neuroscience of consciousness). The main methodological principle of this research is one shared with the radical behaviorists: only intersubjectively accessible data are to be admitted in this natural science of consciousness. If that allegiance, by itself , counts as ‘behaviorism,” then we should all be behaviorists, and indeed the very researchers Baars cites (Singer, Ericsson and Simon, Hilgard, Crick, and Edelman) scrupulously and unapologetically are behaviorists in this minimal sense. They interview their subjects, under controlled conditions, and take their reports seriously–but not as infallible guides to their subjects’ subjectivity.. (shrink)

This paper develops an adaptive fixed-time trajectory tracking controller of an underactuated hovercraft with a prescribed performance in the presence of model uncertainties and unknown time-varying environment disturbances. It is the first time that the proposed method is applied to the motion control of the hovercraft. To begin with, based on the hovercraft's four degrees of freedom model, the virtual control laws are designed using an error transforming function and the fixed-time stability theory to guarantee that the position tracking errors (...) are constrained within the prescribed convergence rates and minimum overshoot. In addition, by combining the Lyapunov direct method and the adaptive radial basis function neural network, the actual control laws are designed to ensure that the velocity tracking errors converge to a small region containing zero while handling model uncertainties and external disturbances effectively. Finally, all tracking errors of the closed-loop system are uniformly ultimately bounded and fixed-time convergent. Results from a comparative simulation study verify the effectiveness and advantage of the proposed method. (shrink)

Analysts such as Steven Horwitz, with strong prior beliefs, are seldom impressed by mere fact and tend to explain away empirical deviations from their theories. The belief that markets are moved only by fundamentals and not by occasional faddism and overshooting rests on the assumption that market participants form their opinions independently, when in fact they are from time to time driven by emulation. The belief that markets are rational and well?informed but government officials and central bankers incompetent is implausible (...) on its face. The period since 1970 has seen bubble after bubble, some of which seemed likely to lead to financial crisis had it not been for the Federal Reserve. (shrink)

Feedback control in neural systems is ubiquitous. Here we study the mathematics of nonlinear feedback control. We compare models in which the input is multiplied by a dynamic gain (multiplicative control) with models in which the input is divided by a dynamic attenuation (divisive control). The gain signal (resp. the attenuation signal) is obtained through a concatenation of an instantaneous nonlinearity and a linear low-pass filter operating on the output of the feedback loop. For input steps, the dynamics of gain (...) and attenuation can be very different, depending on the mathematical form of the nonlinearity and the ordering of the nonlinearity and the filtering in the feedback loop. Further, the dynamics of feedback control can be strongly asymmetrical for increment versus decrement steps of the input. Nevertheless, for each of the models studied, the nonlinearity in the feedback loop can be chosen such that immediately after an input step, the dynamics of feedback control is symmetric with respect to increments versus decrements. Finally, we study the dynamics of the output of the control loops and find conditions under which overshoots and undershoots of the output relative to the steady-state output occur when the models are stimulated with low-pass filtered steps. For small steps at the input, overshoots and undershoots of the output do not occur when the filtering in the control path is faster than the low-pass filtering at the input. For large steps at the input, however, results depend on the model, and for some of the models, multiple overshoots and undershoots can occur even with a fast control path. (shrink)

An iterative learning control algorithm is presented for the force control circuit of a hydraulic cushion. A control scheme consisting of a PI controller, feed-forward and feedback-linearization is first derived. The uncertainties and nonlinearities of the proportional valve, the main system actuator, prevent the accurate tracking of the pressure reference signal. Therefore, an extra ILC FF signal is added to counteract the valve model uncertainties. The unknown valve dynamics are attenuated by adding a fourth-order low-pass filter to the iterative learning (...) control design, which is split up into two second-order low-pass filters to carry out forward and backward filtering and obtain zero-phase filtering. The addition of the ILC signal presents significant improvements in terms of settling time and overshoot of the pressure signal in the cylinder. (shrink)

Proprioception is a crucial sensory modality involved in the control and regulation of coordinated movements and in motor learning. However, the extent to which proprioceptive acuity is influenced by local muscle fatigue is obscured by methodological differences in proprioceptive and fatiguing protocols. In this study, we used high resolution kinematic measurements provided by a robotic device, as well as both frequency and time domain analysis of signals captured via surface electromyography (sEMG) to examine the effects of local muscle fatigue on (...) wrist proprioceptive acuity in 16 physically and neurologically healthy young adults. To this end, participants performed a flexion/extension ipsilateral joint position matching test (JPM), after which a high-resistive robotic task was used to induce muscle fatigue of the flexor carpi radialis (FCR) muscle. The JPM test was then repeated in order to analyze potential changes in proprioceptive acuity. Results indicated that the fatigue protocol had a significant effect on movements performed in flexion direction, with participants exhibiting a tendency to undershoot the target before the fatigue protocol (-1.218°), but overshooting after the fatigue protocol (0.587°). In contrast, in the extension direction error bias values were similar before and after the fatigue protocol as expected (pre = -1.852°, post = -1.237°) and reflected a tendency to undershoot the target. Moreover, statistical analysis indicated that movement variability was not influenced by the fatigue protocol or movement direction. In sum, results of the present study demonstrate that an individual’s estimation of wrist joint displacement (i.e., error bias), but not precision (i.e., variability), is affected by muscular fatigue in a sample of neurologically and physically healthy adults.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Die Vorsokratiker: Ein philosophisches Portrȧt by Thomas BuchheimIstván BodnárThomas Buchheim. Die Vorsokratiker: Ein philosophisches Portrȧt. München: C.H. Beck, 1994. Pp. 262. Paper, DM 48.00.This book is a continuous narrative of highlights of presocratic philosophy. The vista offered by Buchheim is revisionary. The presocratics are behind a curve of the road of the philosophical enterprise. What we usually perceive is a mirage created by the doxographic tradition, emanating ultimately (...) from Aristotle. This much might be uncontroversial: the history of presocratic philosophy has been for the last two centuríes a continuous effort to liberate the remains of those early philosophers from the imputations of later authors. But Buchheim’s project is more ambitious than our ordinary occupation with the presocratics. He postulates a specific, markedly presocratic type of appropriation of the world, and then uses this as a yardstick to elicit a new understanding of the mutilated body of the early texts. Presocratic thought is not theoretical, but rather reactive; it cannot extricate itself from the situation in which it is directed at its object.While some of his discussion is perceptive, the chapters abound in idiosyncratic interpretations. It will suffice to mention only a few of Buchheim’s central claims by way of illustration. Although it has been widely held that Anaximander’s apeiron is not only boundless, but also indefinite, Buchheim’s contention that it should be seen as a disorienting and chaotic matrix which provides no foothold for the discerning and distinguishing mind overshoots the mark. This claim does not mesh well with the allowance in Anaximander that there can be a plurality of simultaneous worlds. There can be a disorienting extension beyond the single cosmos, but several (and as some testimonies would claim, evenly distanced) worlds cannot possibly be separated by a medium which defies the notion of extension altogether.Few will be convinced by Buchheim’s claim that Heraclitus did not formulate a doctrine of opposites because he, coming before Parmenides, could have had only a conception of “counteractive parties in an originally unifying contention” (82), since Heraclitus’ provocative pronouncements would thereby be diluted into mere platitudes. Since Empedocles never calls his rhizömata elements, Buchheim impugns the Empedoclean origin of the four element doctrine. For this he needs to explain away much of the evidence of the fragments. Some of the images Empedocles deploys would suggest a mere juxtaposition of the ingredients, some might indicate some more intimate bond arising between these. As Buchheim aptly notes, the choice in this matter is not obvious. Nevertheless there are places where Buchheim’s interpretation is at a serious disadvantage. Empedocles B8, on the standard reading would rule out the [End Page 521] notion of a phusis (growth, generation) or teleutë- (end, perishing) of any mortal thing, and would allow for the mixιs (mixing) and diallaxιs (separation) of what is mixed together. Immortal things, devoid of generation and perishing by default, are understandably not taken into account here. On Buchheim’s reading, however, Empedoclean rhizömata would be allowed to grow, and hence, by a similar reasoning, to perish.In Chapter 5, Buchheim accuses Aristotle of systematically replacing the dynamically loaded expressions of the ancient atomists, characterizing the ultimate building blocks of nature, with static, geometric idioms. The sole exception where Aristotle does not rob the atomists of this dynamic conception of atomic nature, Buchheim claims, is Physics 8.9 265b23ff. But the uniqueness of the passage rests on Buchheim’s idiosyncratic translation. On the standard interpretation (going back at least to Simplicius) Aristotle asserts only that, according to the atomists, nature performs local motion, and not—as Buchheim would have it—that the nature of the atoms is the very performing of local motion.Contrary to Buchheim’s general characterization of presocratic thought as imbued or integrated with the circumstances of cognition, Anaxagoras’ nous is pure and distinct, not mixed with any other ingredient of the universe. For this reason, Buchheim in his final chapter presents Anaxagoras as a transitional figure between presocratic thought and later, classical metaphysics. The details of this claim, just like the overall characterization of the presocratics, are bound... (shrink)

As Cuba achieves one of the lowest per capita ecological footprints in the world, the country’s overshoot day was on 1 December 2019, while some European countries already reach this limit in February (e.g., Luxembourg), monitoring the environmental preferences of the Cuban younger generation may offer valuable behavioral or pedagogical insights into such a society. As accepted standardized measures exist in the scales of 2-Major Environmental Values (2-MEV) and the General Ecological Behavior (GEB), both measures are following the necessary (...) psychometric requirement, as they have the unique advantage of repeated independent confirmation (and thus provide an external validity). These captured 40 items of reported behavior originating in six subscales that total in a single main cover score. The first one (2-MEV) monitors individual biocentric and anthropocentric preferences with a 20 item-set by relying upon these two higher-order factors of “Preservation” (PRE) and “Utilization” (UTL). Although many language versions already exist (33 in the case of the 2-MEV) for verifying validities and reliabilities of both scales, a country such as Cuba may affirm that this is due to expected cultural differences as well as their exceptionally low global footprint. Additionally, neither the individual connectedness with nature nor the diurnal preferences within the linear structural model showed a substantial relationship to PRE or UTL. Nevertheless, all the regression scores follow the expected positive or negative directions, albeit not all the fit scores turned out as satisfactorily. Apparently, the applied measures secure a good basis for measuring the attitudinal and behavioral framework, but will need further fine tuning to completely monitor the environmental preferences of Cuban adolescents.

The contributions of the great physicist Ludwig Boltzmann to philosophy and biology are not known sufficiently. In philosophy, he was a realist, and much opposed to his colleague's, Mach's, positivism, but also to Berkeley's, Kant's, Hegel's and Schopenhauer's idealisms. In biology, Boltzmann was a passionate Darwinist and tried to explain on the basis of evolution the meaning of photosynthesis as well as the origin of life and of the mind. Boltzmann argued for evolutionary epistemology. Opposing Kant, he derived the fundamental (...) ideas of space, time and causality from the experience of mankind and its ancestors. The laws of thought were acquired in evolution. While they must be broadly true they need not be faultless. Antinomies arise when thought overshoots the mark, i. e. exceeds the limits of the area for which it evolved. As for Boltzmann the experience of the organism in the course of evolution is the only and exclusive source of knowledge, he may be called an absolute Darwinist. A short account of Boltzmann's Darwinian ideas on the origin of morality, on the sense of beauty and on happiness is also given. (shrink)

Here’s a recipe for one kind of argument from the poverty of the stimulus. To start, present an array of linguistic facts to be explained. Begin with a basic observation about form and/or meaning in some language (or, even better, an observation that crosses linguistic borders). Then show how similar forms and/or meanings crop up in other linguistic phenomena. Next, explain how one could account for the array of facts using domain-general learning mechanisms – such as distributional learning algorithms, ‘cut (...) and paste’ operations or analogy. Follow this by introducing other phenomena that resist explanation on a learning-theoretic account. Make it clear that domain-general learning mechanisms would leave the learner short of the target language or would cause the learner to overshoot, resulting in ‘generalizations’ that are not characteristic of the natural language(s) under consideration. The next step in the recipe is to show how the entire array of linguistic phenomena can be explained using ‘abstract’ principles of Universal Grammar. These principles are not likely to be ‘learned’ because, as just witnessed, the kinds of mechanisms that are offered by learning-theoretic approaches to language development would direct learners away from the target, rather than towards it. This raises the alternative to learning, i.e., innate specification. From that point onward, the proof is in the pudding – the argument should contain an empirical demonstration that children never form the kinds of mistaken generalizations that are anticipated by learning-theoretic accounts of language acquisition. Instead, the argument should be supported by a demonstration that children form the correct generalizations, despite the apparent complexity of the phenomena, and in the absence of supporting evidence in the input.

In the chemical production process, the temperature of the continuous reactor has nonlinear characteristics such as large inertia. An improved autodisturbance control method is proposed. By improving the tracking differentiator with adjustable parameters, the expanded state observer and the control structure obtained an improved automatic disturbance rejection control model and realized the optimal control of the nonlinear and large-delay systems. On the process control training system, the experiment of the continuous system process flow is compared with the anti-interference of the (...) Smith predictive compensation system, which uses an optimal set of data. The reactor temperature fluctuates, but the self-resistance is improved. The optimal overshoot of the disturbance is close to 0. Compared with the original antidisturbance controller, the antidisturbance time is not affected by the number of iterations, which reduces the high requirements on the accuracy of the parameters. Therefore, the improved automatic disturbance rejection control improves the operation and enhances the ability to resist external disturbance that changes the controlled object. (shrink)

How should we combine disagreeing expert judgments on the likelihood of an event? A common solution is simple averaging, which allows independent individual errors to cancel out. However, judgments can be correlated due to an overlap in their information, resulting in a miscalibration in the simple average. Optimal weights for weighted averaging are typically unknown and require past data to estimate reliably. This paper proposes an algorithm to aggregate probabilistic judgments under shared information. Experts are asked to report a prediction (...) and a meta-prediction. The latter is an estimate of the average of other individuals’ predictions. In a Bayesian setup, I show that if average prediction is a consistent estimator, the percentage of predictions and meta-predictions that exceed the average prediction should be the same. An “overshoot surprise” occurs when the two measures differ. The Surprising Overshoot algorithm uses the information revealed in an overshoot surprise to correct for miscalibration in the average prediction. Experimental evidence suggests that the algorithm performs well in moderate to large samples and in aggregation problems where individuals disagree in their predictions. (shrink)

Continuing growth, insofar as it increases human environmental impact, is in conflict with the environment. ‘Green growth’, if it increases the absolute size of the economy, is an oxymoron. Environmental limits are discountenanced, a pretence made possible because they are difficult to specify in advance. The consequent weakness in public discourse, both moral and intellectual, has worsened into contradiction as it has become ever more studiously unadmitted. It is obscured with language that is misleading or self-contradictory, and even issues from (...) institutions that exist to respect correctness. At its most conforming it gives rise to overshoot, by which statements meant to sound authoritative are in fact open to ridicule. Such untruthfulness perpetuates climate change inaction, and in a kind of direct action those using such language, contrary to their public or professional duty, could be asked to justify themselves in plain English.

I consider James Hamilton’s discussion of what I term the complete autonomy thesis, according to which no theatrical performance is a performance of some other work. While agreeing with Hamilton that theatrical performances are often artworks in their own right and that theatrical performance is not a derivative or subsidiary art form, I argue that the complete autonomy thesis overshoots the evidence. Some theatrical performances are autonomous, but many belong to an established tradition of close adherence to the texts of (...) dramatic literature. In such cases, we should say both that the performance itself is an artwork and that it is a performance of some literary work. I suggest that this way of understanding things promotes appreciation of both performances themselves and the dramatic works of literature that are employed in their creation. (shrink)

The two-wheeled self-balancing robot is based on the axletree and inverted pendulum. Its balancing problem requires a control action. To speed up the response of the robot and minimize the steady state error, in this article, a grey wolf optimizer method is proposed for TWSBR control based on state space feedback control technique. The controller stabilizes the balancing robot and minimizes the overshoot value of the system. The dynamic model of the system is derived based on Euler formula and (...) linearized to state space representation to enhance the control technique. Then, the GWO optimizes the state feedback controller parameters. Simulation results show that the system reaches the zero steady-state error with less than 2 ms, which proves the effectiveness of the proposed controller over the classical state feedback controller in terms of fast response, very small overall error, and minimum overshoot.

Automatic Generation Control in modern power systems is getting complex, due to intermittency in the output power of multiple sources along with considerable digressions in the loads and system parameters. To address this problem, this paper proposes an approach to calculate Power System Restoration Indices of a 2-area thermal-hydro restructured power system. This study also highlights the necessary ancillary service requirements for the system under a deregulated environment to cater to large-scale power failures and entire system outages. An abrupt change (...) in consumer load demands and disturbances in any control region of a multiarea system causes severe fluctuations in frequency and interarea power exchanges. However, simple Proportional and Integral controllers are most prevalent in the literature to effectively resolve AGC issues, while its integral gain is smaller due to the larger overshoot in transient performance. Therefore, an attempt has been made with a novel control strategy, known as the pseudoderivative feedforward with feedback controller, is developed to keep the interarea power exchanges and the frequency to the specified limits after load changes. A PDFF controller is designed and implemented using the flower pollination algorithm to obtain optimal dynamic performance for different types of potential power flows in a restructured power system under investigation. The proposed PDFF controller localizes the zero at an optimal place that reduces the rise time of the step-response to reduce the excessive overshoot and gives much better dynamic performances as compared to the PI control structure. The Integral Square Error is considered as a performance criterion to derive the optimized gain of the PDFF control structure using FPA. Different PSRI are computed based on the transient response of the 2-area deregulated multisource system and different restoration measures to be taken are also discussed. The simulation results clearly show that the proposed approach is very powerful in decreasing the frequency and tie-power digressions under different load perturbations. (shrink)

With the rapid development of renewable generators such as distributed photovoltaic and profound changes of the power structure, this paper analyzes the frequency characteristics of the power system with high penetration of renewable generations in the process of low-frequency load shedding and discusses the influence of the distributed renewable generator frequency endurance capabilities on the implementation effect of low-frequency load shedding in detail. Finally, the influences of the distributed renewable generator frequency endurance capability and the capacities of the distributed renewable (...) generator on frequency response characteristics of an actual Hunan power grid are simulated. The simulation results show that more distributed photovoltaic capacity without frequency endurance capability leads to deeper frequency drops after the disturbance and requires more basic rounds of load shedding. When the penetration rate of distributed photovoltaic is too high, it may cause load shedding, resulting in power grid load losses and, at the same time, leading to an overshoot phenomenon in the process of frequency recovery. Therefore, the influence of distributed photovoltaic on the control of low-frequency load shedding should be considered when designing low-frequency load shedding schemes for the power grid with high penetration of distributed photovoltaic.

The rapid technological transition requires the adoptive approach to the digital conduct of public and private institutions. Countries and companies strive to integrate a balanced understanding of digital ethics and sustainability concepts from various standpoints, which results in a dispersed and uncategorized knowledge base. This work presents a literature review on digital ethics published from 2010 to 2020 in three technical libraries and one library maintained by the community of philosophers. The investigation process integrates a thorough review of digital ethics (...) concepts in the leading academic libraries using keywords representing various concept applications. This study’s outcome is a quantitative and sectorial categorization of works on digital ethics, followed by a holistic review of concepts, maturity level, and conclusions on each category. This work aims to understand the trends from a technological and philosophical perspective towards designing a sustainable digital ethical frame-work applied in digital services that fulfill sufficiency thresholds of justice and do not foster overshooting of planetary boundaries. The first version of a holistic framework based on the literature review is presented at the end of this work. It will be extended in future work. (shrink)

Contemporary tort theory is dominated by a debate between legal economists and corrective-justice theorists. Legal economists suppose that tortfeasors and tortious wrongs are false targets for cheapest cost-avoiders and avoidable future losses. Corrective-justice theorists argue powerfully that the economic account of tort as search for cheapest cost-avoiders with respect to future accidents does not capture the most fundamental fact about tort adjudication, namely, that the reason we hold defendants liable in tort is that they have wronged their victims and should (...) therefore repair the harm they have done. Deterring cheapest cost-avoiders from committing future harms no more justifies imposing liability in tort than deterring future crime justifies hanging the innocent. This is a powerful critique of the economic theory of tort, but it overshoots the mark. As an account of tort law, corrective justice puts the cart before the horse Tort is a law of wrongs, not just a law of redress for wrongs. Repairing harm wrongly done is the next best way of complying with an obligation not to do harm wrongly in the first place. Rights and remedies form a unity in which rights have priority. Corrective justice is thus an essential but subordinate aspect of tort. This paper develops this line of criticism of corrective-justice theory and offers an alternative account of tort that places primary norms of harm avoidance and respect for rights at its center. On this conception, tort isa law of wrongs, but its distinctiveness lies in the content and character of the wrongs with which it is concerned. At its core, tort is concerned with protecting essential conditions of individual agency. (shrink)

Time is a fundamental dimension of consciousness. Many studies of the “sense of agency” have investigated whether we attribute actions to ourselves based on a conscious experience of intention occurring prior to action, or based on a reconstruction after the action itself has occurred. Here, we ask the same question about a lower level aspect of action experience, namely awareness of the detailed spatial form of a simple movement. Subjects reached for a target, which unpredictably jumped to the side on (...) some trials. Participants expressed their expectancy of a target shift during the upcoming movement, pointed at the target as quickly and accurately as possible before returning to the start posiment to the target shift if required and reproduced the spatial path of the movement they had just made, as accurately as possible, to give an indication of their awareness of the pointing movement. We analysed the spatial disparity between the initial and the reproduced movements on those with a target shift. A negative disparity value, or undershoot, suggests that motor awareness merely reflects a sluggish record of coordinated motor performance, while a positive value, or overshoot, suggests that participants’ intention to point to the shifting target contributes more to their awareness of action than their actual pointing movement. Undershoot and overshoot thus measure the reconstructive and the preconstuctive aspects of action awareness, respectively. We found that trials on which subjects strongly expected a target shift showed greater overshoot and less undershoot than trials with lower expectancy. Conscious expectancy therefore strongly influences the experience of the detailed motor parameters of our actions. Further, a delay inserted either between the expectancy judgement and the pointing movement, or between the pointing movement and the reproduction of the movement, had no effect on visuomotor adjustment but strongly influenced action awareness. Delays during either interval boosted undershoots, suggesting increased reliance on a time-limited sensory memory for action. The experience of action is thus strongly influenced by prior thoughts and expectations, but only over a short time period. Thus, awareness of our actions is a dynamic and relatively flexible mixture of what we intend to do, and what our motor system actually does. (shrink)

Evidence for motion extrapolation at motion offset is scarce. In contrast, there is abundant evidence that subjects mentally extrapolate the future trajectory of weak motion signals at motion offset. Further, pointing movements overshoot at motion offset. We believe that mental and sensorimotor extrapolation is sufficient to solve the problem of perceptual latencies. Both present the advantage of being much more flexible than motion extrapolation.

The deep and lasting changes to human behaviour that are required to address the global environmental crisis necessitate profound shifts in moral foundations. They amount to a change in what individuals and societies conceive of as progress. This imperative raises important questions about the justification, ends, and means of large-scale changes in people’s ethics. In this essay I will focus on the ends—the direction of moral change as prescribed by the goal of sustainable human flourishing. I shall present a meta-ethical (...) critique of anthropocentrism and propose that only an ecocentric ethic can support the sustainable flourishing of humanity. This proposition does not necessarily contradict itself. My claim will be that the values subsumed under the broad concept of anthropocentrism are categorically counterproductive, informing an undesirable concept of “progress”. I support this claim with two lines of argument. On the one hand, the end values of anthropocentrism are shallow and the “flourishing of humanity” is ill-defined. The conceptual constraints of anthropocentrism itself preclude a more concise definition which would take into account the utter dependence of the flourishing of humanity on the health of ecological support structures. On the other hand, pursuing the values that inform the actions of anthropocentrists (which may be identical with the “flourishing of humanity”) leads to unintended and undesirable outcomes, even from the view of the anthropocentrist herself. Those problems are not encountered with an ecocentric ethic, and the conceptual steps necessary to adopt it are not insurmountable. (shrink)
