This study investigates the characteristics of the generalized gravitation equation in a complex spacetime manifold. The newly applied complex spacetime coordinates were designed to integrate peculiar velocity and the receding velocity of the particle into a single coordinate system. On this basis, the Schwarzschild metric solution was extended to a complexified version, and a generalized geodesic equation was derived in the complex spacetime manifold. It was found from the derived gravitation equation that the gravitation interaction depends on the space (...) class='Hi'>deceleration parameter \ and can act as a repulsive force in the giant space scale that satisfies \. These results require a rapid expansion of space in the early universe and suggest that the gravitational interactions of matter are fundamentally linked to the space expansion characteristics.

This article documents the general tendency of seventeenth-century natural philosophers, irrespective of whether they were atomists or anti-atomists, to regard space, time and matter as magnitudes having the same internal composition. It examines the way in which authors such as Fromondus, Basson, Sennert, Arriaga, Galileo, Magnen, Descartes, Gassendi, Charleton as well as the young Newton motivated their belief in the isomorphism of space, time and matter, and how this belief reflected on their views concerning the relation between geometry and physics. (...) Special attention is paid to the fact that most of the authors mentioned above regarded rarefaction and condensation, on the one hand, and acceleration and deceleration, on the other hand, as analogous phenomena, which consequently had to be explained in similar terms.

In recent years, there has been a rapidly growing body of work in the social sciences that underscores the prevalence of the phenomenon of ‘social acceleration'—the speeding up of social life— in many parts of the Western world. Although research on social acceleration has tended to analyze the phenomenon on a social-structural level, there is also a need to investigate how social acceleration has ‘ramifications for the socially dominant forms of self-relation’. One way to gain a more in-depth understanding of (...) this facet of social acceleration is to investigate the speeding up of social life through the prism of the self. The central argument of this article is that there are at least five images of the self which can be associated with the social acceleration phenomenon: the ‘detached’ self, the ‘reflexive’ self, the ‘reinventive’ self, the ‘stationary’ self and the ‘decelerating’ self. By explaining how these kinds of self relate to the speeding up process, we seek to advance a more nuanced and sophisticated theory of social acceleration, which captures some of the complexities and paradoxes that the phenomenon involves.

Research on surprise relevant to the cognitive-evolutionary model of surprise proposed by Meyer, Reisenzein, and Schützwohl is reviewed. The majority of the assumptions of the model are found empirically supported. Surprise is evoked by unexpected events and its intensity is determined by the degree if schema-discrepancy, whereas the novelty and the valence of the eliciting events probably do not have an independent effect. Unexpected events cause an automatic interruption of ongoing mental processes that is followed by an attentional shift and (...) attentional binding to the events, which is often followed by causal and other event analysis processes and by schema revision. The facial expression of surprise postulated by evolutionary emotion psychologists has been found to occur rarely in surprise, for as yet unknown reasons. A physiological orienting response marked by skin conductance increase, heart rate deceleration, and pupil dilation has been observed to occur regularly in the standard version of the repetition-change paradigm of surprise induction, but the specificity of these reactions as indicators of surprise is controversial. There is indirect evidence for the assumption that the feeling of surprise consists of the direct awareness of the schema-discrepancy signal, but this feeling, or at least the self-report of surprise, is also influenced by experienced interference. In contrast, facial feedback probably does contribute substantially to the feeling of surprise and the evidence for the hypothesis that surprise is affected by the difficulty of explaining an unexpected event is, in our view, inconclusive. Regardless of how the surprise feeling is constituted, there is evidence that it has both motivational and informational effects. Finally, the prediction failure implied by unexpected events sometimes causes a negative feeling, but there is no convincing evidence that this is always the case, and we argue that even if it were so, this would not be a sufficient reason for regarding this feeling as a component, rather than as an effect of surprise.

In lieu of an abstract, here is a brief excerpt of the content:Math Anxiety:Making Room to BreatheValerie Allen (bio) and Todd Stambaugh (bio)"Don't do that to me, Professor," the student said, and everybody laughed, for by this late in the semester, the atmosphere was relaxed. The instructor in question had just reached the point in a worked problem when they could move from reasoning about specific numbers to stating a general principle: x≤y≤z, meaning that y—the value we sought—was always going (...) to be greater than or equal to one value (x) and less than or equal to the other (z). The student who had spoken had earned everyone's affection over the weeks, open about their difficulties with math, ready to risk being wrong, and to ask obvious questions that others may have been reluctant to owning. They had hung in there, despite presenting a classic case of math anxiety, a syndrome long recognized in the scholarship of teaching and learning.Among math anxiety's many symptoms, breathing disruption ranks high: hyperventilation (rapid breathing) and hypoventilation (barely or not breathing). When the energy-conserving parasympathetic nervous system is overtaken by the energy-expending sympathetic nervous system, the long exhalations that decelerate the heart rate are replaced by short, panting puffs from the upper lungs. The timed test provides the perfect environment for math anxiety to flourish. Stress diverts cognitive resources needed for procedural execution, so working memory consequently shrinks.Self-rated metrics for math anxiety have been in place for decades (Richardson and Suinn). Relatively trivial interventions can yield nontrivial results: deep breathing exercises and positive affirmations have a beneficial impact, as does writing about one's nerves immediately prior to an exam (Brunyé et al.). More systemic changes require a reorientation in teaching whereby conceptual mistakes are positively rewarded as opportunities for learning; students compose questions instead of answers; students solve problems together rather than perform solo (Boaler).Return now to that opening scenario to watch it become stereotype incarnate: the student was mature, Black, and female; the teacher, younger, white, and male; her comment was triggered by his shift from a specific [End Page 217] set of numbers into symbolic notation. There is robust evidence to demonstrate that certain demographics are consistently underrepresented in the U.S. math community: women and "African-Americans, Hispanics, American Indians, Alaska Natives, and Pacific Islanders," according to the Mathematical Association of America (MAA) ("Resources for Minority"). Routinely feeling that they do not belong, such groups are particularly vulnerable to math anxiety.Several remedies for such disparity suggest themselves: appointing more women and people of color in the profession; one-on-one tutorial assistance; research projects about the students' personal environment; privileging pre-test, low-stakes work over timed tests; assigning group rather than individual work. When all is said and done, however, such strategies "have little to do with mathematics content" (Martin 304). Mathematicians still need to be able to conceptualize, describe, and manipulate abstract objects, and there seems to be a suspicion that, at heart, abstraction is gendered masculine and colored white.It is possible that the rhetorical immediacy and context-dependence of Black English has misguidedly reinforced such a perception. For poet June Jordan, Black English "devolves from a culture that abhors all abstraction" (Jordan 367). Psychiatrist Alvin Poussaint asks, "Is there a way to say metamorphosis in Ebonics?" (O'Malley). Yet, despite Black English's avoidance of nominalization and similar verbosities that afflict academic prose, abstract logical reasoning flourishes in vernacular idiom, as linguist William Labov demonstrated half a century ago. Our aim is not to explain the asymptote in Black English but rather to consider a feature characteristic of those very minority cultures historically underrepresented in math—storytelling—and to ask how it may be foregrounded in mathematics, where it is decisively sidelined. Storytelling has been claimed by every culture and ethnic group at some point as the repository of wisdom, practical skills, religious beliefs, and shared identity and values; but when it gets corralled into the category of "fiction," and when it gets opposed to "fact," a narrowed concept of truth dispatches storytelling to kindergarten and recreational math. Word problems may supply scenarios but offer none of a plot's satisfactions... (shrink)

This paper focuses on the infamous case of Hwang Woo Suk, the South-Korean national hero and once celebrated pioneer of stem cell research. After briefly discussing the evolution of his publication and research scandal in Science, I will attempt to outline the main reactions that emerged within scientific and bioethical discourses on the problem of research misconduct in contemporary biosciences. What were the ethical lapses in his research? What kind of research misconduct has been identified? How this kind of misconduct (...) affects scientific integrity? How to avoid it? Focusing on these questions, the paper interprets the Hwang’s case as a case study that might shed light on the worst aspects of highstakes global science. This case presents a group of problems that might endanger scientific integrity and public trust. Regulatory oversight, ethical requirements and institutional safeguards are often viewed by the scientific community as merely decelerating scientific progress and causing delays in the application of treatments. The Hwang’s case represents how unimpeded progress works in contemporary science. Thus, the case might shed light on the often neglected benefits of “the social control of science”. (shrink)

In timing perception studies, the timing of one event is usually manipulated relative to another, and participants are asked to judge if the two events were synchronous, or to judge which of the two events occurred first. Responses are analyzed to determine a measure of central tendency, which is taken as an estimate of the timing at which the two events are perceptually synchronous. When these estimates do not coincide with physical synchrony, it is often assumed that the sensory signals (...) are asynchronous, as though the transfer of information concerning one input has been accelerated or decelerated relative to the other. Here we show that, while this is a viable interpretation, it is equally plausible that such effects are driven by shifts in the criteria used to differentiate simultaneous from asynchronous inputs. Our analyses expose important ambiguities concerning the interpretation of simultaneity judgement data, which have hitherto been underappreciated. (shrink)

There is a relationship between time and technology which has been obvious since the classical philosophies of time. Even telling the time necessitates technologies relating to measuring and counting. Technological developments have changed the temporal state of our reality. Key terms such as deceleration, synchronisation, prevention and de-temporalisation point to relevant problem areas in this respect. This yearbook, whose thematic focus is 2021, endeavours to reveal new technological and philosophical perspectives on the temporal conditions in which we think, communicate, (...) work and live.

Instead of relying on the usual price elasticity technique, this book combines economic and engineering analysis to study economic growth and energy demands to the year 2000. It asserts that future energy demand will be determined by two basic factors--the gross national product and the efficiency with which energy is used to produce this output in the household, commercial, industrial, and transport sectors of the economy.Labor hours multiplied by a productivity factor results in the GNP. This study predicts that, in (...) the long run, productivity in the United States will recover most of the sharp losses registered in the past five years. The study points out the decelerating population growth, the higher number of women in the labor force, and new investments as having an influence on this situation.After projecting the size and composition of each of the four energy consuming sectors that account for the total GNP. Energy and Economic Growth estimates efficiency improvements for each. It shows, for example, that higher levels of thermal insulation will reduce sharply energy needs for household heating and cooling. Similarly, the study notes that improvements in energy consumption per dollar of output can be made for each of the energy intensive manufacturing industries, nothing that although the savings in energy are significant, none is a consequence of pushing improvements to known technological limits. Finally, the book establishes the price elasticities that are inherent in the calculated energy requirements and checks these against elasticity estimates made by other researchers. (shrink)

This is a review of the book: Sheehan H. Marxism and the Philosophy of Science. A Critical History. The First Hundred Years. (L.: Verso, 2017. XII. 450 p.). The keynote of the book serves the conviction that Marxism is a sort of “super-theory” that can explain not only any social and political life, but also profound philosophy of science, including natural science. Science is presented in the book as a form of social practice. The main idea of the Marxist philosophy (...) of science is the status of the theory of dialectical materialism. The author shows that Marxist ideas could be considered as the origins of many disciplines: the sociology of science, the history of science, the history of technology; they had a noticeable effect on non-Marxist thought as well. However, Stalinism and Lysenkoism significantly decelerated the development of the Marxist philosophy of science. (shrink)

We have demonstrated, using the Cantor dust method, that the statistical distribution of appearance and disappearance of rodents species (Arvicolid rodent radiation in Europe) follows power laws strengthening the evidence for a fractal structure set. Self-similar laws have been used as model for the description of a huge number of biological systems. With Nottale we have shown that log-periodic behaviors of acceleration or deceleration can be applied to branching macroevolution, to the time sequences of major evolutionary leaps (global life (...) tree, sauropod and theropod dinosaurs postural structures, North American fossil equids, rodents, primates and echinoderms clades and human ontogeny). The Scale-Relativity Theory has others biological applications from linear with fractal behavior to non-linear and from classical mechanics to quantum mechanics. (shrink)

‘Eine weite Wohnung unter freiem Himmel’? On the Aesthetics of Gardens of the Senses Although the common experience of nature and gardens engages all the senses, historical analysis of garden theory shows a clear tendency to reduce green spaces to their imagery and to take the visual arts as the model for garden design. A counter-tendency to this primacy of vision has, however, lately emerged -- namely, gardens of the senses or healing gardens, which accentuate also the tactile and olfactory (...) qualities of vegetation and materials. The literature on gardens of the senses provides useful empirical guidelines for garden designers, but on a rather eclectic theoretical basis that applies mainly to private jardins de plaisir. Nevertheless, the accentuation of tactile and olfactory qualities in gardens constitutes a source of well-being, and contributes to a deceleration of life, a positive experience of the natural order and rhythm, and the habitability of a place. Moreover, they are informal laboratories for the education of the senses, and their empirical taxonomies may be integrated into an aesthetic theory of sensory design. (shrink)

The form of an action has a strong influence on the interaction between humans. According to their mood, people may perform the same gesture in different ways, such as gently or rudely. These aspects of social communication are named vitality forms by Daniel Stern, represent a mean to establish a direct and immediate connection with others. Indeed, the expression of different vitality forms enables us to communicate our affective states and at the same time the perception of these vitality forms (...) enables people around us to understand how we feel in that moment. In the last years of research, different fMRI studies have been carried out to investigate the neural correlates of vitality forms recognition and execution. Moreover, recent psychophysics studies conducted from our research group have demonstrated the presence of an affective contagion effect, during which vitality forms expressed by an agent affect the action perception and the motor response of the receiver. This means that vitality forms expressed by others can influence our mood positively or negatively, modulating as consequence our behavior. Note that vitality forms pervade our lives in a continuous manner and thus they are not expressed and perceived only during social interactions. For example, when we observe an artistic representation at the theatre, the dynamic postures of dancers, together with an alternation of acceleration and deceleration in their movements, communicate to us different affective states. Also when we are in a museum in front of a painting, lines, colors and shapes used by the artist can elicit in us different sensations and modify our attitude. In this view, with the aim to extend the concept of vitality forms from neuroscience and psychology to other disciplines of study, we dedicate part of this review to discuss how art, in all its forms, can be considered a pure expression of vitality forms.

Concussion is a form of mild traumatic brain injury that can occur as a result of contact to the head or other parts of the body that causes a rapid acceleration-deceleration force to the brain that may cause a functional disturbance in an individual’s ability to concentrate or learn new information. Contrary to popular belief, it is not a bruise to the brain, and there is usually nothing detectable on standard imaging such as a computed tomography or magnetic resonance (...) imaging. Symptoms and signs are therefore important to detect and include decreased levels of consciousness, headache, nausea, difficulty concentrating, memory loss, and poor coordination. These signs and symptoms usually occur within minutes after the injury but may also appear several hours or even days later. (shrink)

Life history data, attractiveness ratings of male photographs, and attitudes towards partnership and child-rearing of 321 women were used to test four evolutionary models (quantitative reproductive strategy, male short-age, polygyny indication, and maternal reproductive interests) which attempt to explain the influence of family composition on reproductive strategies. Links between early menarche and other markers of reproductive strategy were investigated. Childhood stress and absence of a father figure, whether genetically related or not, were found to have accelerated menarche whereas having younger (...) siblings decelerated it. Early menarche was associated with attractiveness ratings, the number of partners desired for the immediate future, and the early onset of intimate relationships. It was not linked with sociosexual orientation, mate choice criteria, and investment in the subjects’ own children, but these three markers were interrelated. The implications of the findings for the four evolutionary models are discussed. (shrink)

Over and above differences in terminology and cultural background, we try to show that the quantum physicist, David Bohm, and poststructuralist philosopher, Gilles Deleuze, shared a common aim in thought: to replace the classical image of reality, which is still dominant in our time, with a metaphysics finally in agreement with the concepts and results of relativity, quantum mechanics andcontemporary biology. For these two thinkers, the world of things that are well individuated in space and time, and ordered according to (...) mechanical relations of cause and effect, are nothing but the momentary expression of an “undivided wholeness in flowing movement” that constitutes its true ontological ground. By means of this new metaphysics, the world of daily experience and classical science appears as the explicit manifestation or development of implicate order that undivided wholeness contains virtually in itself at deeper and deeper levels of envelopment and imbrication. The explicit world is the result of a process of repetition, deceleration and temporal stabilization, triggered by the interaction of our measuring instruments – technical devices, sensory organs and motors, a priori forms and categories of the understanding – with moving wholeness, the thinking and observing subject of which represents a momentary and partial reflection rather than a solitaryand autonomous fragment. By criticizing the classical image of thecorrespondence/adequation of being and thought, Bohm and Deleuzeshow that the thought seeking to grasp this wholeness in flowingmovement inevitably interacts with it – by modifying, recreating andaccomplishing it in one direction rather than another. Thought thusresembles a dance that tries to harmonize with the universal flux thatgenerates and carries it away in a single movement with matter. **************************************************************************************************** ***********************Para além das diferenças de terminologia e de background cultural, tenta-se aqui mostrar que o físico quântico David Bohm e o filósofo pós-estruturalista Gilles Deleuze tiverem um objetivo comum de pensamento: substituir a imagem clássica da realidade, ainda dominante em nossa época, por uma metafísica finalmente de acordo com os conceitos e resultados da relatividade, da mecânica quântica e da biologia contemporânea. Para estes dois pensadores, o mundo das coisas bem individuadas no espaço e no tempo, e ordenadas conforme as relações mecânicas de causa e efeito, não é nada outro que a expressão momentânea de uma “Totalidade indivisa em devir” que constitui seu verdadeiro fundamento ontológico. Pelo meio desta nova metafisica, o mundo da experiência cotidiana e da ciência clássica aparece como a manifestação explicita ou desenvolvida da ordem implícita que a totalidade indivisa contém virtualmente nela mesma em níveis de envolvimento e de imbricação sempre mais profundos. O mundo explícito é o resultado de um processo de repetição, desaceleração e estabilização temporal, desencadeado pela interação de nossos instrumentos de medição -- aparelhos técnicos, órgãos sensoriais e motores, formas “a priori” e categorias do entendimento – com uma totalidade movente no qual o sujeito pensante e observante representa um reflexo momentâneo e parcial ao invés de um fragmento solitário e autônomo. Ao criticar a imagem clássica da correspondência/adequação entre o ser e o pensamento, Bohm e Deleuze mostram finalmente que o pensamento que intenta capturar esta Totalidade em devir interage inevitavelmente com ela, modificando-a, recriando-a e realizando-a em uma direção ao invés de outra. O pensamento se aparenta assim a uma dança que tenta se harmonizar com o flux universal que o gera e o leva em um movimento só com a matéria.Palavras-chave: Bohm; Deleuze; totalidade indivisa em devir; física quântica; pós-estruturalismo; ontologia.

In his Ecolinguistics, Stibbe (2020) declares the story of economic growth (the continuous increase in production and consumption) as the ‘master narrative’ that is at the same time the most harmful story we live by. This paper explains where this story of growth comes from and describes how it supplants or suppresses alternatives, such as stories of thrift and sharing. By connecting the biosemiotic model of Funktionskreis (e.g. Uexküll, 1920) as “the primary mechanism of meaning making” (Kull 2020) to cognitive (...) linguistics (e.g. Lakoff, 2009) and critical discourse analysis (e.g. van Leeuwen, 2018), this paper explores how stories of thrift and sharing can be turned into activism that seeks to reframe waste as surplus that can be shared; but they can also hide the old business models of the master narrative. Stories of sharing are often erased to protect corporate interests. Narratives of sharing can be duplicitous, especially in the context of the ‘sharing economy’. Attempts at reframing resources and energy as common wealth owned by everyone are squelched by the master narrative in contexts like resource and energy distribution. Can the new story of shrinking and degrowth become a new alternative to the master narrative and promote new decelerated semiotic habits (Maran, 2023) for a more fulfilling life with less (e.g. Herrmann 2022)?

The general attributes of ecosystems are examined and a naturally occurring reference ecosystem is established, comparable with the isolated system of classical thermodynamics. Such an autonomous system with a stable, periodic input of energy is shown to assume certain structural characteristics that have an identifiable thermodynamic basis. Individual species tend to assume a state of least dissipation; this is most clearly evident in the dominant species (the species with the best integration of energy acquisition and conservation). It is concluded that (...) ecosystem structure results from the antagonistic interaction of two nearly equal forces. These forces have their origin in the Principle of Most Action (least dissipation or least entropy production) and the universal Principle of Least Action. Most action is contingent on the equipartitioning of the energy available, through uniform interaction of similar individuals. The trend to Least action is contingent on increased dissipation attained through increasing diversity and increasing complexity. These principles exhibit a basic asymmetry. Given the operation of these opposing principles over evolutionary time, it is argued that ecosystems originated in the vicinity of thermodynamic equilibrium through the resonant amplification of reversible fluctuations. On account of the basic asymmetry the system was able to evolve away from thermodynamic equilibrium provided that it remained within the vicinity of ergodynamic equilibrium (equilibrium maintained by internal work, where the opposing forces are equal and opposite).At the highest level of generalization there appear to be three principles operating: i) maximum association of free-energy and materials; ii) energy conservation (deceleration of the energy flow) through symmetric interaction and increased homogeneity; and iii) the principle of least action which induces acceleration of the energy flow through asymmetrical interaction. The opposition and asymmetry of the two forces give rise to natural selection and evolution. (shrink)

A half century ago electronic fetal monitoring was rushed into clinical use with the promise that the secrets of fetal heart rate decelerations had been discovered and that the newly discovered knowledge would prevent cerebral palsy with just in time cesarean sections preventing babies from experiencing asphyxia, which was thought to be the primary cause of cerebral palsy. In the years since electronic fetal monitoring’s debut, it has been discovered that asphyxia is a rare cause of cerebral palsy. At the (...) same time electronic fetal monitoring use increased to 85% of all labors, the C-section rate increased to 33% without an attributable decrease in the rate of cerebral palsy.

We present a mini review of the Stueckelberg mechanism, which was proposed to make the abelian gauge theories massive as an alternative to Higgs mechanism, within the framework of Minkowski as well as curved spacetimes. The higher the scale the tighter the bounds on the photon mass, which might be gained via the Stueckelberg mechanism, may be signalling that even an extremely small mass of the photon which cannot be measured directly could have far reaching effects in cosmology. We present (...) a cosmological model where Stueckelberg fields, which consist of both scalar and vector fields, are non-minimally coupled to gravity and the universe could go through a decelerating expansion phase sandwiched by two different accelerated expansion phases. We discuss also the possible anisotropic extensions of the model. (shrink)

The holographic principle was proposed by Nobel laureate Gerard ‘t Hooft in the 1990s and it has also been modeled by Leonard Susskind and Stephen Hawking. We’ve heard light mentioned with regard to the fundamental nature of reality for a long time; God said Let there be light, we are the light of the world, etc. But we haven’t investigated a possible role for the speed of light in our illnesses. This paper will do just that. The central premise is (...) that light’s “speed” is a reflection of the degree to which the observer is removed from its source. In its Platonic state, light’s speed is zero. It is light from which time, by degrees, emerges. The Big Bang can be envisioned as a sphere, the center of which is a point, Alpha. Via expansion, Alpha becomes a sphere, Omega, by degrees, where each degree is c. For any given Alpha, the circumference of a circle on the sphere, Omega, is a set of resonant points that represent the speed of light or “end of time.” Every radius—every line drawn from Alpha to Omega—is an arrow of time, a parallel universe. Alpha and Omega increase in tandem, maintaining the degree of separation required by special relativity, E=mc^2. The holographic sphere of points equidistant from the Big Bang on which we find ourselves is not the only sphere of points equidistant from the Big Bang. There are spheres that are smaller and larger than ours. Where an arrow of time intersects a sphere-brane of light’s speed will be treated here as a “2D hologram.” For an observer behind the hologram, reality will appear to be accelerating/expanding. For an observer in front of it, reality will appear to be decelerating/contracting. For an observer at the speed of light, time is no longer a variable. (shrink)

When describing motion along both the horizontal and vertical axes, languages from different families express the elements encoding verticality before those coding for horizontality (e.g., going up right instead of right up). In light of the motor grounding of language, the present study investigated whether the prevalence of verticality in Path expression also governs the trajectory of arm biological movements. Using a 3D virtual-reality setting, we tracked the kinematics of hand pointing movements in five spatial directions, two of which implied (...) the vertical and horizontal vectors equally (i.e., up right +45° and bottom right −45°). Movement onset could be prompted by visual or auditory verbal cues, the latter being canonical in French (“en haut à droite”/up right) or not (“à droite en haut”/right up). In two experiments, analyses of the index finger kinematics revealed a significant effect of gravity, with earlier acceleration, velocity, and deceleration peaks for upward (+45°) than downward (−45°) movements, irrespective of the instructions. Remarkably, confirming the linguistic observations, we found that vertical kinematic parameters occurred earlier than horizontal ones for upward movements, both for visual and congruent verbal cues. Non-canonical verbal instructions significantly affected this temporal dynamic: for upward movements, the horizontal and vertical components temporally aligned, while they reversed for downward movements where the kinematics of the vertical axis was delayed with respect to that of the horizontal one. This temporal dynamic is so deeply anchored that non-canonical verbal instructions allowed for horizontality to precede verticality only for movements that do not fight against gravity. Altogether, our findings provide new insights into the embodiment of language by revealing that linguistic path may reflect the organization of biological movements, giving priority to the vertical axis.

Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the _Principia_ also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system.

Homonyms, i.e. ambiguous words like ‘score’, have different meanings in different contexts. Previous research indicates that all potential meanings of a homonym are first accessed in parallel before one of the meanings is selected in a competitive race. If these processes are automatic, these processes of selection should even be observed when homonyms are shown subliminally. This study measured the time course of subliminal and supraliminal priming by homonyms with a frequent and a rare meaning in a neutral context, using (...) a lexical decision task. In the subliminal condition, priming across prime-target asynchronies ranging from 100 ms to 1.5 s indicated that the dominant meaning of homonyms was facilitated and the subordinate meaning was inhibited. This indicates that selection of meaning was much faster with subliminal presentation than with supraliminal presentation. Awareness of a prime might decelerate an otherwise rapid selection process.

As a domain of political intervention, speed is a meeting ground for projects of domination and tactics of emancipation, for logics of exclusion coexisting with various forms of collisions, intersections and amalgamations. Instead of reducing the ‘need for speed’ to a linear and unequivocal process, this article makes the case for thinking about speed as an arena of conflict, subject to brutal accelerations but also to at least momentary decelerations. Taking the example of Karachi, where road accidents and larger controversies (...) around transport played a prominent role in the violent postcolonial transformations of the city, it argues that from these collisions emerged a form of political power premised on the regulation of traffic flows. It concludes that moving-power always exceeds the initial intentions of those setting it in motion as it simultaneously builds on and disrupts the forces that give every city its vitality, that is, on the vitalism of speed.

Of the many topics worthy of discussion regarding older adults and bioethics, two seem to provide an especially pointed opportunity for reflection on our aging society. First, is aging itself something that biomedical researchers should focus on as a deficit to be overcome through eventual anti-aging treatments? While aging may not fall neatly into the disease category, it is clearly the primary susceptibility factor for the innumerable diseases of older adults, and therefore its potential deceleration consistent with the compression (...) of morbidity might constitute a salutary biomedical goal. The aging society is no panacea to those who suffer from a host of chronic illnesses and feel overwhelmed by the burden of years. Second, we must concentrate on the most challenging problematic of our current aging society, assuming that anti-aging technologies will only become available in future decades. One immense problem is the harsh reality of irreversible progressive dementia, which will serve here as an example of the rise of chronic illness, for which age itself is the primary risk factor.

Aristotle provides a theory of irregular motion that is tripartite and the passage ought to be interpreted in such a way as to explain this tripartite motion. _Akmē_ is not a ‘top speed’ as it is generally translated, but (...) a point in an object’s motion when _epitasis_ must become _anesis_. Although the terms _epitasis_ and _anesis_ cover ‘acceleration’ and ‘deceleration’ they cannot be reduced to them. (shrink)

This paper traces the history of accelerationism as a political philosophy, from its inception at Warwick University to its deployment by avowed white supremacists. Probing its philosophical commitment to a both a deterministic philosophy of history and a sacrificial logic of politics, I argue that even the initial elaborations of (non-race-based) accelerationism contained the seed of its development into violent white supremacy. The conclusion assesses a politics of deceleration as a strategy for countering accelerationism, ultimately arguing for the superiority (...) of a Benjaminian politics of the emergency brake.

In this study, we analyzed the relationship between the amodal (semantic) development of words and two popular emotional norms (emotional valence and arousal) in English and Spanish languages. To do so, we combined the strengths of semantics from vector space models (vector length, semantic diversity, and word maturity measures), and feature-based models of emotions. First, we generated a common vector space representing the meaning of words at different developmental stages (five and four developmental stages for English and Spanish, respectively) using (...) the Word Maturity methodology to align different vector spaces. Second, we analyzed the amodal development of words through mixed-effects models with crossed random effects for words and variables using a continuous time metric. Third, the emotional norms were included as covariates in the statistical models. We evaluated more than 23,000 words, whose emotional norms were available for more than 10,000 words, in each language separately. Results showed a curve of amodal development with an increasing linear effect and a small quadratic deceleration. A relevant influence on the amodal development of words was found only for emotional valence (not for arousal), suggesting that positive words have an earlier amodal development and a less pronounced semantic change across early lifespan.

Most offenders, even persistent offenders, eventually desist from crime, and the fastest period of deceleration in the frequency of offending is in the early twenties. This article summarises results from a longitudinal study of desistance from or persistence in crime in this age range, illustrated by three case histories. A key finding is that, because of their deep prior engagement in crime, would-be desisters from repeat offending need to make many adjustments to their patterns of daily life. The authors (...) explain why virtue ethics has been found to be a valuable resource in theorising these results. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Literary Common GroundLee Rust BrownLet me make note of a few things that have occurred to me during this conference. Some of these will be observations; some will be practical inferences. One of them, though, involves the crossing of an expectation, or maybe a fear, I had brought with me to Minneapolis. Since this has to do with the whole tone of the conference, we might as well (...) begin with it.It, of course, was the question of the polemical nature of this gathering. Would this conference be diagnostic and denunciatory in nature, or would it seek to start something truly new? Certainly we all feel the need of something new—not new, either, in the sense that movements or ideological positions claim to be new, but in the sense of a fresh gathering of common attention in the place where literature is, the place where each of us who loves literature already goes alone. This would be a possibility for something original rather than just another novelty—which makes the question of polemics all the more urgent. An association that founded itself in complaint would be only one more identity-group making a virtue out of its grudge. And the grudge, in that case, would have been a sad reflex of feeling superseded and powerless.But where have the polemics against current orthodoxies been? I am delighted not to have heard them in any strenuous capacity. Even their relative absence hasn’t commanded any extended attention, and that may be an even more telling point. I take this to be partly the result of foresight and good sense. But the clean air here has been more than a reward for our mutual constraint. Instead, it seems evidence of the fact [End Page 193] that, when literature occupies our attention, there is no need for self-defense. Justice, or justification, happens by itself when we “do our own work,” as Socrates recommended.What is our own work, then? This association has made a point, it seems, of declining to prescribe what it should be. The only thing we are absolutely sure of is that its subject is literature, and that its standards and rewards should be of a literary nature. From there the field opens up—and this conference has succeeded in keeping it open in some very concrete ways.Let’s think briefly about the two panels we attended yesterday. The morning panel on “Intellectual Craftsmanship” seemed unified in its concern with the disciplined ways by which we commit ourselves to literary experience. Literature itself, as well as what we do with it, teaches us this discipline, which is “aesthetic” in every sense of that word. Roger Shattuck set the tone when he described the discipline of reading as an issue of preparation and assimilation on the one hand, and as a kind of complete perceptual openness on the other. Such openness, in our normal experience, allows us to be surprised, to see actual things, perhaps, instead of their institutional categories. But literature also requires that we craft our receptivity. The surprises we prepare ourselves to undergo are achieved breakthroughs, which makes them no less unpredictable but all the more deeply affecting.Criticism cultivates such surprising experience. (I think experience is the crucial word, by the way, since everyone on that first panel seemed to be devoted to a kind of free empiricism.) The spectacular moments of visionary power that Robert Alter isolated in Dickens are places that startle and disturb us—and we track our own surprise, and intensify it, when we look closely at how those dark places of power emerge from Dickens’s refiguring of a world where darkness otherwise tends toward an entirely unredeemable opacity. We have to read “synesthetically,” as Shattuck says, “with both eyes open,” to let ourselves be for a moment blinded by such literary places.Once again, the discipline of reading—devotedly and resistantly—frees us for the achieved experience. Slowing down, in Sven Birkerts’s sense of “retardation and deceleration,” is precisely a matter of stepping into a field of experience shaped (or, in an auditory sense, fostered and conserved) by the special demands of literature. It... (shrink)

Temporality is an under-researched area in entrepreneurship and business ethics, even though entrepreneurs are particularly affected by a fast-paced work environment. How do they position themselves in relation to the acceleration of time in order to construct meaning for their activity? We draw on fifty-four semi-structured interviews with entrepreneurs to outline the different ways in which they perceive a faster pace of work. We show how the meaning they give to their activity varies according to whether they accept or resist (...) the acceleration of time: (1) By claiming to accept a high work rate, entrepreneurs may see work as a way of keeping busy, having fun, forgetting, or achieving efficiency; (2) by asserting that they resist the acceleration of time, they view work as a way of setting ethical goals, doing their job better, experiencing unexpected encounters, or being creative. These two different perspectives on time and meaning are not incompatible: It is possible that achieving a harmonic balance between periods of acceleration and deceleration of time may foster the construction of meaningful entrepreneurship.

Based on a sociological survey carried out in a camp for asylum seekers in Belgium, the article questions the modes of existence in this “out of place” and “out of time” that is the camp. Behind the apparent emptiness of waiting in a decelerated present, the investigation highlights three temporalities that together shape the breathing of the camp and the living conditions of asylum seekers: the rhythm of the framework that holds together daily life, the cycle and the passage that (...) gives a sense of the ordeal and finally the singular time of the articulations between present, past and future which characterize the “being in time” of asylum seekers. After exploring these three temporalities, the author proposes a concept that allows them to hold together in order to understand the texture of time that unfolds in these “out of place”, “out of time” that are the camps.

In order to resolve the cosmological constant problem, the notion of reference frame is re-examined at the quantum level. By using a quantum non-linear sigma model (Q-NLSM), a theory of quantum spacetime reference frame is proposed. The underlying mathematical structure is a new geometry endowed with intrinsic second central moment (variance) or even higher moments of its coordinates, which generalizes the classical Riemannian geometry based on only first moment (mean) of its coordinates. The second central moment of the coordinates directly (...) modifies the quadratic form distance which is the foundation of the Riemannian geometry. At semi-classical level, the second central moment introduces a flow which continuously deforms the Riemannian geometry driven by its classical Ricci curvature, which is known as the Ricci flow. A generalized equivalence principle of quantum version is also proposed to interpret the new geometry endowed with at least second moment. As a consequence, the spacetime is stabilized against quantum fluctuation, and the cosmological constant problem is resolved within the framework. With an isotropic positive curvature initial condition, the long flow time solution of the Ricci flow exists, the accelerating expansion universe at cosmic scale is an observable effect of the spacetime deformation of the normalized Ricci flow. A deceleration parameter − 0.67 consistent with measurement is obtained by using the reduced volume method introduced by Perelman. Effective theory of gravity within the framework is also discussed.

BackgroundTraumatic brachial plexus injury (TBPI) causes a sensorimotor deficit in upper limb (UL) movements.ObjectiveOur aim was to investigate the arm–forearm coordination of both the injured and uninjured UL of TBPI subjects.MethodsTBPI participants (n = 13) and controls (n = 10) matched in age, gender, and anthropometric characteristics were recruited. Kinematics from the shoulder, elbow, wrist, and index finger markers were collected, while upstanding participants transported a cup to their mouth and returned the UL to a starting position. The UL coordination (...) was measured through the relative phase (RP) between arm and forearm phase angles and analyzed as a function of the hand kinematics.ResultsFor all participants, the hand transport had a shorter time to peak velocity (p < 0.01) compared to the return. Also, for the control and the uninjured TBPI UL, the RP showed a coordination pattern that favored forearm movements in the peak velocity of the transport phase (p < 0.001). TBPI participants' injured UL showed a longer movement duration in comparison to controls (p < 0.05), but no differences in peak velocity, time to peak velocity, and trajectory length, indicating preserved hand kinematics. The RP of the injured UL revealed altered coordination in favor of arm movements compared to controls and the uninjured UL (p < 0.001). Finally, TBPI participants' uninjured UL showed altered control of arm and forearm phase angles during the deceleration of hand movements compared to controls (p < 0.05).ConclusionThese results suggest that UL coordination is reorganized after a TBPI so as to preserve hand kinematics.

Two classic theories maintain that aging evolves either because of alleles whose deleterious effects are confined to late life or because of alleles with broad pleiotropic effects that increase early‐life fitness at the expense of late‐life fitness. However, empirical studies often reveal positive pleiotropy for fitness across age classes, and recent evidence suggests that selection on early‐life fitness can decelerate aging and increase lifespan, thereby casting doubt on the current consensus. Here, we briefly review these data and promote the simple (...) argument that aging can evolve under positive pleiotropy between early‐ and late‐life fitness when the deleterious effect of mutations increases with age. We argue that this hypothesis makes testable predictions and is supported by existing evidence. (shrink)

When efficiently used for action, tool becomes part of body, with effect on the spatial temporal movement parameters and body size perception. Until now, no previous investigation was reported about tool embodiment in Parkinson’s disease (PD), that is a neurological disease characterized by several sensory and motor symptoms affecting body and action. We enrolled fourteen individuals affected by PD and eighteen healthy individuals as controls. We studied the spatial-temporal parameters on self-paced free pointing movements task, via an optoelectronic system, before (...) and after a short training in which a 27 cm long rod was used to point toward a far target. Moreover, we investigated changes in estimation of arm length through the Tactile Estimation Task. After the tool use training, controls showed changes in spatial-temporal parameters: they were slower to perform movements and reported higher value of deceleration, respect to the baseline. However, such a difference did not emerged in the PD individuals. In the Tactile Discrimination Task, no difference emerged before and after the tool use training in both groups. Our results were suggestive of possible difficulties of tool embodiment process in PD. We discussed our results in relation to aberrant multisensory integration as well as in terms of the effect of PD sensory and motor symptoms on body schema plasticity. The present study points at a novel way to conceive PD sensory motor signs and symptoms, in terms of their effect on individuals’ body representation. (shrink)

Comme l’organisme vivant chez Hegel, le capital apparait chez Marx comme sujet capable de produire ses contenus particuliers et ce faisant se reproduire lui-même. Le processus de reproduction prend la forme de trois circuits (capital-argent, capital productif et capital-marchandise) qui renvoient aux rythmes de la valorisation, de l’accumulation et de la réalisation de la valeur. La croissance implique la concordance entre les trois. La crise économique, c’est-à-dire la perturbation d’un schéma de reproduction, résulte de l’autonomisation conjoncturelle d’un de ces rythmes (...) par rapport aux deux autres. Alors que la crise des années 1970 est due à la chute du taux de profit (décélération du rythme de valorisation), celle de 2007-2009 est due aux politiques appliquées pour faire face à la crise des années 1970, qui ont restauré le profit au détriment du salaire et ont ainsi transformé une crise de valorisation en une crise de réalisation. La crise économique se transforme ainsi en crise de reproduction sociale et d’hégémonie politique, que la pandémie ne fait qu’aggraver. (shrink)

India now constitutes approximately 17% of the world’s population and has a high proportion of younger people. Philosophy for school children aims to create better citizens of the future. In this article, I establish the need to teach philosophy to children in schools, especially in India. Subsequently, I discuss the readiness of Indians to accept philosophy in the school curriculum, their conundrum in understanding the need for philosophy in a school setting, and the East-West dilemma concerning the teaching of philosophy (...) in schools. The concept of self-realization is important in education. Socrates claimed that an unexamined life is not worth living. However, the self-realization concept of the West differs from that in India. While the former perceives self-realization as a way to construct a good individual, the latter has always emphasized the cessation of the individual and focused on the incomprehensible truth human languages cannot capture. Western philosophy is concerned with questioning, inquiry, and the problems of philosophy. The East is concerned with bringing such questioning to an end. Matthew Lipman focuses on increasing curiosity, accelerating the thinking process, teaching logic and formal reasoning, and the intellectual enhancement of children. Indian philosophy, yoga, and meditation are all concerned with the cessation of consciousness. The key question concerns the approach one may choose to adopt in teaching philosophy – accelerating or decelerating the thought processes of children? Indian parents are the primary decision-makers in their children’s education, and sometimes throughout their careers and lives. Unless clarity emerges in the Indian and global community regarding this issue, there is no clear starting point for teaching philosophy to children in India. This article aims to raise critical awareness among global citizens regarding this conundrum in the collective Indian psyche. Unless the world’s psyche is inserted into the place of the Indian psyche, the great barrier between the West and the East regarding philosophy in the school curriculum cannot be bridged. (shrink)

ABSTRACT A growth mixture modeling (GMM) analysis of neutralization scores in 1,830 youth across six waves of data revealed evidence of a three-class model in which moral neutralization either increased (low accelerating), decreased (high decelerating), or remained the same (moderate stable) over time. Controlling for age, sex, race, group assignment, and Wave 1 delinquency, an analysis of covariance revealed a significantly greater increase in Wave 6 delinquency in the moderate stable group than in the low accelerating group. When the average (...) neutralization score was added as a control variable, the low accelerating group was highest, the moderate stable group next highest, and the high decelerating group lowest on Wave 6 delinquency. These results indicate that change in the pattern of neutralization scores (accelerating, stable, decelerating) may be as important as the level of moral neutralization at any particular point in time in determining the effect of neutralization on future delinquency.

Rattus norvegicus is an important experimental organism and interesting to evolutionary biologists. The recently published draft rat genome sequence1 provides us with insights into both the rat's evolution and its physiology. We learn more about genome evolution and, in particular, the adaptive significance of gene family expansions and the evolution of rodent genomes, which appears to have decelerated since the divergence of mouse and rat. An important observation is that some regions of genomes, many in noncoding regions, show very high (...) sequence conservation, while others show unexpectedly fast evolution. Both of these may be pointers to functional significance. BioEssays 26:1039–1042, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

The aims of this study were to analyze the peak physical demands in elite futsal by quantifying the most demanding scenarios of match play and to identify the differences between playing positions and the seasonal trend for five different rolling average time windows. The most demanding scenarios of external load from distance, speed, acceleration, and deceleration variables were obtained from 14 elite futsal players using a local positioning system during 15 official matches in the premier Spanish Futsal League. The (...) results showed an extremely large effect of the time window for all dependent variables in all positional groups. Another important finding of this study was that, in regard to the seasonal trend, only defenders reported clear moderate-large positive trends for high-speed running efforts, high-acceleration efforts, and high-deceleration efforts. Finally, moderate-large individual differences in player means for all dependent variables and clear differences between games for most dependent variables were found, suggesting how likely contextual factors may exert an influence on how “demanding” the most demanding scenarios are. The findings of this study provide coaches and strength and conditioning coaches further knowledge of the peak physical demands in elite futsal competition. This valuable information may lead to a more precise position-specific training prescription. (shrink)
