Globalized workplace is increasingly moving into complex jobs requiring their employees to exhibit complex knowledge and complex skills. Though acquiring such complex skills or knowledge requires longer time, the pace of business puts pressure on organizations to accelerate the time it takes for their employees to become proficient in their jobs. This shift has challenged the conventional training and learning strategies, structure, methods, instructional design and delivery methodologies generally used by training providers and by the organizations. This paper (...) presents the preliminary research findings of a Doctorate research carried out using Grounded theory approach with over 71 in-depth interviews with leading experts in over 40 industries. Preliminary findings suggest that certain e-learning strategies and platforms hold better potential over others to successfully accelerate time-to-proficiency of individuals in leading organizations. This paper provides first look at 10 e-learning strategies and how those could be orchestrated before, during and after a formal training program to develop job-ready learners in shorter time.

ABSTRACT This article attempts to situate land art in the deserts of the US Southwest in terms of the works’ relation to and rupture with more traditional genres (seventeenth to twentieth centuries) of parks, gardens, and landscape architecture. It argues that the earlier works provide implicit answers to questions concerning Earth’s meaning and offer models of flourishing habitation. In contrast, the more recent works, all constructed in the era of the great acceleration (the Anthropocene), pose questions having to do (...) with new challenges posed by climate change and the devastation of the Earth.

Professional skill development was never as critical as it has become with the changing nature of globalized work place. With the change in pace of business, the customer expectations from organizations has increased in terms of squeezed time-to-market, faster response to customer needs and demands for better services. Organizations are increasingly becoming focused on how workplace professional skill development of employees can be structured or orchestrated to shorten time-to-professional expertise of their employees. It is becoming increasingly challenging for (...) organizations to develop their employees at faster rate so that they can perform their job even more efficiently and effectively. The longer time-to-proficiency of employees may impact time-to-market of organizations and may also result in losing business to competition. This paper presents the review of previous research studies on current modes and modalities of professional skill development in organizations and present initial findings on training and development approaches taken by organizations to accelerate time-to-professional expertise of their employees. This paper is aimed at making a wider call-for-research in the area of organizations’ focus on shortening the time to develop professional skills of their employees. (shrink)

This chapter presents that our model is that of a network whose time is historically constructed by the events that occur within it – inter‐individual communications, intra‐individual categorization, forgetting by erasure or reinforcement – and not the other way around: far from being part of a temporal framework that is always there, these events produce time. The historical‐sociological register shows that the psychological and an historical determinations of the perceived acceleration of time thus interpreted have been (...) over‐determined by the primacy given to communication on cognition in our developed societies. The chapter proposes two complementary interpretations such as psychological interpretation and socio‐historical interpretation, both of which are logically in line with our model of the structure and evolution of our network of individual actors. It examines the meaning that macroscopic expression of entropy can have in our model of a complex socio‐cognitive network of individual actors. (shrink)

This study aimed to explore practices and strategies that have successfully reduced time-to-proficiency of the workforce in large multinational organisations and develop a model based on them. The central research question of this study was: How can organisations accelerate time-to-proficiency of employees in the workplace? The study addressed three aspects: the meaning of accelerated proficiency, as seen by business leaders; the business factors driving the need for shorter time-to-proficiency and benefits accrued from it; and practices and strategies (...) to shorten time-to-proficiency of the workforce. 85 participants (n=85) from 7 countries who represented 10 economic sectors, 20 business sectors and 28 industry groups contributed 66 successful bounded project cases. A qualitative research approach was used. Data were collected through in-depth interviews with project leaders and by collecting additional project case documents. Data were analysed using thematic analysis to identify the themes in the data. Matrix analysis was then used to perform within-case and cross-case analysis to compare the project cases. 11 overarching themes were developed from the data analysis, out of which two overarching themes explained the characteristics of job-role proficiency and accelerated proficiency, while three overarching themes described the magnituide and scale of time-to-proficiency business problem, business drivers for accelerating proficiency and business benefits of reduced time-to-proficiency. Six overarching themes revealed the business practices employed by organisations to reduce time-to-proficiency: (1) Defining business-driven proficiency measures in terms of expected business outcomes from a job role; (2) Developing a proficiency reference map of all the inputs, conditions and roadblocks that determine or influence how required business outcomes are being produced in a job role; (3) Sequencing an efficient proficiency path of activities and experiences ordered to produce the desired business outcomes in the shortest possible time; (4) Manufacturing accelerated contextual experiences by leveraging on-the-job opportunities or training interventions in a compressed time-frame; (5) Promoting an active emotional immersion through engagements, consequences, stakes, feedback and proficiency assessments; and (6) Setting up a proficiency eco-system, providing timely support to performers while doing the job such as enabling job environment, highly involved manager, structured mentoring from experts, purposeful social connectivity with peers, leveraging subject matter experts and on-demand performance support systems. Organisations orchestrated these six business practices as an input-output-feedback system to reduce time-to-proficiency of the workforce. A conceptual model (Accelerated Proficiency Model) was developed representing interactions among six business-level practices/processes as a closed-loop system to explain the concept and process of accelerated proficiency in the workplace. These practices were implemented through a set of twenty-four strategies proven successful in various contexts. The strategies employed were much beyond the boundaries of conventional training interventions. The job itself acted as the primary mechanism to accelerate proficiency. A two-level hierarchical framework (6/24 framework of strategies) was also constructed in the form of a checklist consisting of six practices and twenty-four strategies for practitioners. Overall, the findings of this research study contribute significantly to the body of knowledge on accelerated proficiency. In particular, the conceptual model and the framework developed in this study can be implemented across a range of contexts, business sectors, job types and settings to reduce time-to-proficiency of the workforce.

The most reliable source for a reconstruction of Galileo's progress toward a science of motion is the series of undated fragmentary notes on that subject preserved in Codex A of the Galilean manuscripts at Florence. A gathering of such fragments was published by Favaro in the National Edition of Galileo's works, following the Discorsi. The more sophisticated fragments are clearly associated with the composition of that work, and show a definite and consistent understanding of acceleration. Eliminating those, it will (...) be found that the earlier notes fall into recognizable groups. First, there are some that refer to “moment of gravity”, or to the impetus of a body along a line of descent, and are associated with the discussion of inclined planes in De motu. Second, some refer to descent along arcs and chords of circles, associated with Galileo's letter of 29 November 1602 to Guido Ubaldo. These first two groups of notes do not explicitly refer to accelerated motion, and should not be assumed to do so implicity, where such an assumption can be avoided. (shrink)

In his Contributions to Philosophy, Martin Heidegger introduces "acceleration" as one of the three symptoms--along with "calculation" and the "outbreak of massiveness"--of our technological way of "being-in-the-world." In this article, I unpack the relationship between these symptoms and draw a twofold conclusion. First, interpreting acceleration in terms of time pathologies, I suggest the self is becoming increasingly fragmented and emotionally overwhelmed from chronic sensory arousal and time pressure. This experience makes it difficult for us to qualitatively (...) distinguish what matters to us in our everyday lives, resulting in a pervasive cultural mood of indifference, what Heidegger calls "profound boredom." Second, by drawing on Heidegger's hermeneutic method, I argue that the practice of mainstream psychology, by adopting the reductive methodology of the empirical sciences, largely ignores our accelerated socio-historical situation, resulting in therapeutic models that have a tendency to construct and perpetuate the very pathologies the psychologist is seeking to treat.

It is a remarkable fact that all processes occurring in the observable universe are irre- versible, whereas the equations through which the fundamental laws of physics are formu- lated are invariant under time reversal. The emergence of irreversibility from the funda- mental laws has been a topic of consideration by physicists, astronomers and philosophers since Boltzmann's formulation of his famous \H" theorem. In this paper we shall discuss some aspects of this problem and its connection with the dynamics of (...) space-time, within the framework of modern cosmology. We conclude that the existence of cosmological horizons allows a coupling of the global state of the universe with the local events deter- mined through electromagnetic processes. (shrink)

Critical theory has recently charted the rise of an unprecedented wave of social acceleration transforming Western capitalism. Within that body of work, a tendency has emerged to frame this new temporality as a stable structure lacking in the possibility for visions of alternatives, let alone for substantive revolt or challenge. This essay argues that recent struggles like Occupy and 15-M experimented with an alternative, utopian temporality that challenged and disrupted acceleration, revealing the latter to be prone to generating (...) and expanding the conditions of temporal struggle. Acceleration is therefore unstable, and cannot be adequately understood apart from its increasing cultivation of visions of and experiments in other temporalities. (shrink)

This article constitutes a contribution to the critique of the political economy of contemporary higher education. Its notes form, intended to open "windows" on the thorny issue of metrics permeating academia on both the local/national and global levels, facilitates a conceptualization of the academic law of value as a mechanism responsible for regulating the tempo and speed of academic labor in a higher education system subsumed under capital. First, it begins with a presentation of the Marxist approach to acceleration (...) and measure. Second, it presents the academic law of value as a socially necessary impact/time. Third, it conceptualizes a figure of capital that operates in the contemporary global higher education system. Fourth, it describes the conditions of operation of merchant capital within higher education and explores the close links of global university rankings, metadata providers, and the academic publishing industry. As a fifth and final point, the analysis turns to Central Eastern Europe and the case study of Poland to demonstrate that, to function properly, the academic law of value needs to be imposed by political means, that is, through policy reforms that establish and legitimize the sets of parameters and criteria for the evaluation of academic labor. In conclusion, the argument suggests that the domination of merchant capital over academic labor, resulting in the latter's ongoing and uncontrolled acceleration, cannot be overcome without addressing not so much the issue of private property but, first and foremost, the politically and socially defined metrics.

Digital communication between humans fundamentally changes the nature of communication. One inherent change is the acceleration of communication as a systematic change in societal life, particularly in the workplace. Often, the aim is to release time resources. However, the acceleration of communication also leads to the opposite: a lack of time. This paradoxical development can be based on an acceleration cycle whereby technologies seem to be a solution on the micro-level, but they are also a (...) significant part of the problem on the meso-level.

The high pace business environment poses great competition among firms. The key to an organisation’s survival is its workforce. Time taken by the workforce to reach to full proficiency in their job role takes very long in certain job roles. Thus, shortening time-to-proficiency of employees is a critical business problem for today’s organisations. This qualitative research study explored the proven practices and strategies that have successfully reduced time-to-proficiency of the workforce in various settings. A total of 93 (...) participants from seven countries participated in the research study. Bounded project case was used as sampling unit and unit of analysis in this study. This study collected 67 successful project cases with the evidence of significant reduction in time-to-proficiency of the workforce in their settings. These project cases spanned across nine economic sectors, 20 business sectors and 28 industry groups. This study revealed that project leaders across the board used six practices to successfully reduced the time-to-proficiency. The purpose of this paper is present the model of accelerated proficiency at the workplace developed in this study. (shrink)

We live in turbulent times, our world is changing at accelerating speed. Information is everywhere, but wisdom appears in short supply when trying to address key inter-related challenges of our time such as; runaway climate change, the loss of biodiversity, the depletion of natural resources, the on-going homogenization of culture, and rising inequity. Living in such times has implications for education and learning. This book explores the possibilities of designing and facilitating learning-based change and transitions towards sustainability. In 31 (...) chapters contributors from across the world discuss (re)emerging forms of learning that not only assist in breaking down unsustainable routines, forms of governance, production and consumption, but also can help create ones that are more sustainable. The book has been divided into three parts: re-orienting science and society, re-connecting people and planet and re-imagining education and learning. This is essential reading for educators, educational designers, change agents, researchers, students, policymakers and entrepreneurs alike, who are concerned about the well-being of the planet and convinced of our ability to do better. The content and related issues can be discussed on the blog by editor Arjen Wals: Transformative learning. 'We are living in times of incertitude, complexity, and contestation, but also of connectivity, responsibility, and new opportunities. This book analyses the consequences of these times for learning in formal, non-formal, and informal education. It explores the possibilities offered by the concept of sustainability as a central category of a holistic paradigm which harmonizes human beings with Earth. To change people and to change the world are interdependent processes - this book contributes to both.' Moacir Gadotti, Director of Paulo Freire Institute, São Paulo, Brazil 'I hope you share my excitement about the innovations for sustainability that this book catalogues and analyses. While the ecological news is grim, the human news is not. Even in a time of accelerating change, people are showing their enormous capacities to learn, adapt, restore and protect.' From the Foreword by Juliet Schor, author of ‘True Wealth: how and why millions of Americans are creating a time-rich, ecologically-light, small-scale high-satisfaction economy’ 'This book implies a ‘culture of critical commitment’ in educational thinking and practice - engaged enough to make a real difference to social-ecological resilience and sustainability but reflexively critical enough to learn constantly from experience and to keep options open in working for a sustainability transformation.'

Hartmut Rosa advances an account of the temporal structure of society from the perspective of critical theory. He identifies three categories of change in the tempo of modern social life: technological acceleration, evident in transportation, communication, and production; the acceleration of social change, reflected in cultural knowledge, social institutions, and personal relationships; and acceleration in the pace of life, which happens despite the expectation that technological change should increase an individual's free time. According to Rosa, both (...) the structural and cultural aspects of our institutions and practices are marked by the "shrinking of the present," a decreasing time period during which expectations based on past experience reliably match the future. When this phenomenon combines with technological acceleration and the increasing pace of life, time seems to flow ever faster, making our relationships to each other and the world fluid and problematic. It is as if we are standing on "slipping slopes," a steep social terrain that is itself in motion and in turn demands faster lives and technology. As Rosa deftly shows, this self-reinforcing feedback loop fundamentally determines the character of modern life. (shrink)

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)

Time is a necessary element in understanding AI art. Firstly, time reveals the historical process by which art-theoretical predicates move from the unmarked to the marked, which can thus be utilized as a defense for arguing the legitimacy of AI art as art. Furthermore, AI art should be seen as a “new” art that is temporally ahead of the descriptive forms of art theory. Secondly, time provides a unique interpretation of AI artworks’ characteristics and aesthetic experience. The (...) absence of experience, the de-depth of AI artworks, and the “short experience/short memory” aesthetic mode of the masses are closely linked to the scarcity of time in an age of acceleration. Finally, time reflects the loss of “aura” and the new end of art that AI art may bring about. Time provides a defense and explanation of AI art, as well as a perspective for reflecting on the development of art in contemporary times. (shrink)

This article aims to present the life and work of German thinker Hartmut Rosa as a philosopher of interest for nursing. Although his theoretical framework remains fairly unknown in the nursing domain, its main key concepts open up a philosophical and sociological approach that can contribute to the understanding of a wide range of study phenomena related to nurses, nursing, and healthcare. The concepts of social acceleration, alienation, and resonance are useful to explore healthcare organizations' performance by bringing the (...) time dimension of modernity to the center; to grasp nurses' experiences of caring for patients; and to understand nurses as agents endowed with the capacity to deploy their political agency to create alternative forms of relationship to themselves, to others, and the world, challenging the institutional order of healthcare organizations when it fails to resonate with their professional ethos. In this article, we propose Hartmut Rosa's theoretical framework as a new and inspiring phenomenological and critical lens that should be further explored to advance knowledge concerning phenomena that are found at the crossroads of the nursing domain and other fields of knowledge.

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.

Decoding the human genome in the past decades has brought into focus a computationally intensive operation through DNA profiling. The typical search space for these kinds of problems is extremely large and requires specialized hardware and algorithms to perform the necessary sequence analysis.

Our approach places careful consideration on preprocessing of (...) DNA datasets and runtime performance, while exploiting the full capabilities of the heterogeneous platform it runs on. Finally, we evaluate our models against real-world DNA sequences. (shrink)

The existence of current–time universe’s acceleration is usually modeled by means of two main strategies. The first makes use of a dark energy barotropic fluid entering by hand the energy–momentum tensor of Einstein’s theory. The second lies on extending the Hilbert–Einstein action giving rise to the class of extended theories of gravity. In this work, we propose a third approach, derived as an intrinsic geometrical effect of space–time, which provides repulsive regions under certain circumstances. We demonstrate that (...) the effects of repulsive gravity naturally emerge in the field of a homogeneous and isotropic universe. To this end, we use an invariant definition of repulsive gravity based upon the behavior of the curvature eigenvalues. Moreover, we show that repulsive gravity counterbalances the standard gravitational attraction influencing both late and early times of the universe evolution. This phenomenon leads to the present speed up and to the fast expansion due to the inflationary epoch. In so doing, we are able to unify both dark energy and inflation in a single scheme, showing that the universe changes its dynamics when \, at the repulsion onset time where this condition is satisfied. Further, we argue that the spatial scalar curvature can be taken as vanishing because it does not affect at all the emergence of repulsive gravity. We check the goodness of our approach through two cosmological fits involving the most recent union 2.1 supernova compilation. (shrink)

Accelerating Expansion explores some of the philosophical implications of modern cosmology, focused on the significance that the discovery of the accelerating expansion of the Universe has for our understanding of time, geometry, and physics. The appearance of the cosmological constant in the equations of general relativity allows one to model universes in which space has an inherent tendency towards expansion. This constant, introduced by Einstein but subsequently abandoned by him, returned to centre stage with the discovery of the accelerating (...) expansion. This pedagogically-oriented essay begins with a study of the most basic and elegant relativistic world that involves a positive cosmological constant, de Sitter spacetime. It then turns to the relatives of de Sitter spacetime that dominate modern relativistic cosmology. Some of the topics considered include: the nature of time and simultaneity in de Sitter worlds; the sense in which de Sitter spacetime is a powerful dynamical attractor; the limited extent to which observation can give us information about the topology of space in a world undergoing accelerated expansion; and cosmologists' favourite sceptical worry about the reliability of evidence and the possibility of knowledge, the problem of Boltzmann brains.

Motivated by the ethical dilemma in managerial financial reporting decisions, we explore and reveal an unintended “crash” consequence following accelerated patenting information dissemination. Employing the American Inventor’s Protection Act (AIPA) that accelerated the publication of patent applications, we find that accelerated dissemination of patenting information increases stock price crash risk. This effect is stronger when treated firms are technologically closer to their rival firms and more concerned about proprietary costs. Further analyses indicate that, the heightened crash risk following the AIPA (...) is attributable to managers shifting towards less timely bad news disclosures. Overall, our study documents that accelerated dissemination of patenting information induces managers to strategically withhold negative information, which adds to the comprehension of what and how (un)ethical decisions are undertaken by managers.

Curved multi-dimensional space-times (5D and higher) are constructed by embedding them in one higher-dimensional flat space. The condition that the embedding coordinates have a separable form, plus the demand of an orthogonal resulting space-time, implies that the curved multi-dimensional space-time has 4D de-Sitter subspaces (for constant extra-dimensions) in which the 3D subspace has an accelerated expansion. A complete determination of the curved multi-dimensional spacetime geometry is obtained provided we impose a new type of “equivalence principle”, meaning that there (...) is a geodesic which from the embedding space has a rectliniar motion. According to this new equivalence principle, we can find the extra-dimensions metric components, each curved multi-dimensional spacetime surface’s equation, the energy-momentum tensors and the extra-dimensions as functions of a scalar field. The generic geodesic in each 5D spacetime are studied: they include solutions where particle’s motion along the extra-dimension is periodic and the 3D expansion factor is inflationary (accelerated expansion). Thus, the 3D subspace has an accelerated expansion. (shrink)

In such a context, Palestinians and international solidarity activists find themselves confronting a quintessential 21 st century activist dilemma: how to craft a strategy of what Paul Virilio calls “popular defense” at a time when everyone seems to be implicated in the machinery of global violence? I argue that while this dilemma represents a formidable challenge for Palestinians, it also helps explain why the Palestinian struggle is increasingly able to build bridges with wider struggles for global justice, ecological sustainability, and indigenous rights.

In modern capitalist societies, companies are exposed to enormous pressure to accelerate. However, it has increasingly become apparent that the social and economic acceleration which is the result of systemic imperatives tends to produce conflict both on the micro-level of personal temporal patterns and rhythms and on the macro-ecological level, where it tends to undermine the proper times for natural regeneration and reproduction. Corporations are increasingly called upon as corporate citizens to fulfil their responsibilities to stakeholders such as employees (...) or ecosystems. Business ethics approaches therefore seek to develop strategies for fulfilling this responsibility in view of these conflicts created by social acceleration. In this contribution, we first present a diagnosis of acceleration imperatives for companies based on a sociological analysis of social acceleration. Then we examine the normative aspects of conflicts created by acceleration for employees and the ecosphere using the sociological conception of resonance. We attempt to articulate conceptually the normative requirements for a business ethics which are capable of dealing with the problems of social acceleration in corporations with a particular focus on a resonant stakeholder approach.

Time has multiple aspects and is difficult to define as one unique entity, which therefore led to multiple interpretations in physics and philosophy. However, if the perception of time is considered as a composite time concept, it can be decomposed into basic invariable components for the perception of progressive and support-fixed time and into secondary components with possible association to unit-defined time or tense. Progressive time corresponds to Bergson’s definition of duration without boundaries, which (...) cannot be divided for measurements. Time periods are already lying in the past and fixed on different kinds of support. The human memory is the first automatic support, but any other support suitable for time registration can also be considered. The true reproduction of original time from any support requires conditions identical to the initial conditions, if not time reproduction becomes artificially modified as can be seen with a film. Time reproduction can be artificially accelerated, slowed down, extended or diminished, and also inverted from the present to the past, which only depends on the manipulation of the support, to which time is firmly linked. Tense associated to progressive and support fixed time is a psychological property directly dependent on an observer, who judges his present as immediate, his past as finished and his future as uncertain. Events can be secondarily associated to the tenses of an observer. Unit-defined time is essential for physics and normal live and is obtained by comparison of support-fixed time to systems with regular motions, like clocks. The association of time perception to time units can also be broken. Einstein’s time units became relative, in quantum mechanics, some physicist eliminated time units, others maintained them. Nevertheless, even the complete elimination of time units is not identical to timelessness, since the psychological perception of progressive and support-fixed time still remains and cannot be ignored. It is not seizable by physical methods, but experienced by everybody in everyday life. Contemporary physics can only abandon the association of time units or tenses to the basic components in perceived time. (shrink)

We obtained an exact solution for a uniformly accelerated Unruh–DeWitt detector interacting with a massless scalar field in (3 + 1) dimensions which enables us to study the entire evolution of the total system, from the initial transient to late-time steady state. We find that the conventional transition probability of the detector from its initial ground state to excited states, as derived from time-dependent perturbation theory over an infinitely long duration of interaction, is valid only in the transient (...) stage and is invalid for cases with proper acceleration smaller than the damping constant. We also found that, unlike in (1 + 1)D results, the (3 + 1)D uniformly accelerated Unruh– DeWitt detector in a steady state does emit a positive radiated power of quantum nature at late-times, but it is not connected to the thermal radiance experienced by the detector in the Unruh effect proper.

By focusing on the unique velocity and over-stimulation of metropolitan life, Georg Simmel pioneered an interpretation of cultural boredom that has had a significant impact on contemporary social theory by viewing it through the modern experience of time-pressure and social acceleration. This paper explores Simmel's account of boredom by showing how--in the frenzy of modern life--it has become increasingly difficult to qualitatively distinguish which choices and commitments actually matter to us. Furthermore, this emotional indifference invariably pushes us towards (...) more excessive and risky behavior, towards, what I call, "extreme aesthesia." Insofar as novel experiences quickly become routine in the technological age, it appears that only extreme sensations and experiences can break the spell of boredom, allowing us to momentarily feel strongly for something.

Within Special Relativity accelerated systems can be described as those systems in which standard clock synchronism does not hold. Therefore, the ε -generalized Lorentz equations derived by Winnie are the equations governing accelerated systems. The ε -generalized equation for time is used in analyzing two cases of the clock paradox: (1) the case in which a clock travels in a straight line, stops, and returns, and (2) the case in which a clock travels with uniform velocity in a circular (...) path. The treatment of case (1) of the paradox within this generalization of the Special Theory is compared with Møller's treatment of it within the General Theory. (shrink)

ABSTRACTThe political impact of “social acceleration” has recently attracted much attention in sociology and political theory. The concept, however, has remained entirely unexplored in the discipline of history. Although numerous British historians have noted the prominent position of acceleration in the late‐Victorian and Edwardian imagination, these observations have never expanded beyond the realm of rhetorical flourish. The present paper attempts to build a two‐way interdisciplinary bridge between British political history and the theories of social acceleration that have (...) been posited in the social sciences, arguing that both British political historians and acceleration theorists have much to gain from further dialogue.

In reliability engineering and lifetime analysis, many units of the product fail with different causes of failure, and some tests require stress higher than normal stress. Also, we need to design the life experiments which present methodology for formulating scientific and engineering problems using statistical models. So, in this paper, we adopted a partially constant stress accelerated life test model to present times to failure in a small period of time for Gompertz life products. Also, considering that, units are (...) failing with the only two independent causes of failure and tested under type-I generalized hybrid censoring scheme the data built. Obtained data are analyzed with two methods of estimations, maximum likelihood and Bayes methods. These two methods are used to construct the point and interval estimators with the help of the MCMC method. The developed results are measured and compared under Monte Carlo studying. Also, a data set is analyzed for illustration purposes. Finally, some comments are presented to describe the numerical results. (shrink)

Investigation of joint torque constraint compliance is of significance for robot manipulators especially working in complex environments. A lot of which is attributed to that, on the one hand, it is beneficial to the improvement of both safety and reliability of the mission execution. On the other hand, the energy consumption required by the robot to complete the desired mission can be reduced. Most existing schemes do not take the joint torque limit and other inherent physical structure limits in a (...) manipulator into account at the same time. In addition, many unavoidable uncertainties such as the external environmental disturbance and/or electromagnetism interferences in the circuit system may influence the accuracy and effectiveness of the task execution for a robot. In this study, we cast light on the acceleration level control of redundant robot manipulators considering both four physical constraint limits and interference rejection. A robust unified quadratic-programming-based hybrid control scheme is proposed, where the joint torque constraints are converted as two inequality constraints based on the robots’ dynamics equation. A recurrent-neural-network-based controller is designed for solving the control variable. Numerical experiments performing in PUMA 560 manipulator and planer manipulator illustrate that a rational torque distribution is obtained among the joints and the considered physical structural vectors are all restricted to the respective constraint range. In addition, even disturbed by the noise, the manipulator still successfully tracks the desired trajectory under the proposed control scheme. (shrink)

This article investigates the rate at different periods of the evolutionary process on Earth. The investigation is based on the author's previous investigations of the growth of evolutionary complexity and on other recent investigations of the rates of scientific evolution and information technology. The measures of the evolutionary rates are given in terms of their doubling times, being several million years for animal evolution, and ranging from a million years to some thousand years for human cultural evolution. After the Galilean (...) scientific revolution the doubling time shows a dramatic drop to about only twenty years and is found to be still shorter for modern information technology. The result shows that the totality of the evolutionary processes on Earth follows a superexponentially increasing rate, characterized by steadily decreasing doubling times. (shrink)

We present a stochastic theory for the nonequilibriurn dynamics of charges moving in a quantum scalar field based on the worldline influence functional and the close-time-path (CTP or in-in) coarse-grained effective action method. We summarize (1) the steps leading to a derivation of a modified Abraham-Lorentz-Dirac equation whose solutions describe a causal semiclassical theory free of runaway solutions and without pre-acceleration patholigies, and (2) the transformation to a stochastic effective action, which generates Abraham-Lorentz-Dirac-Langevin equations depicting the fluctuations of (...) a particle’s worldline around its semiclassical trajectory. We point out the misconceptions in trying to directly relate radiation reaction to vacuum fluctuations, and discuss how, in the framework that we have developed, an array of phenomena, from classical radiation and radiation reaction to the Unruh effect, are interrelated to each other as manifestations at the classical, stochastic and quantum levels. Using this method we give a derivation of the Unruh effect for the spacetime worldline coordinates of an accelerating charge. Our stochastic particle-field model, which was inspired by earlier work in cosmological backreaction, can be used as an analog to the black hole backreaction problem describing the stochastic dynamics of a black hole event horizon.

Mining time series data is of great significance in various areas. To efficiently find representative patterns in these data, this article focuses on the definition of a valid dissimilarity measure and the acceleration of partitioning clustering, a common group of techniques used to discover typical shapes of time series. Dissimilarity measure is a crucial component in clustering. It is required, by some particular applications, to be invariant to specific transformations. The rationale for using the angle between two (...) time series to define a dissimilarity is analyzed. Moreover, our proposed measure satisfies the triangle inequality with specific restrictions. This property can be employed to accelerate clustering. An integrated algorithm is proposed. The experiments show that angle-based dissimilarity captures the essence of time series patterns that are invariant to amplitude scaling. In addition, the accelerated algorithm outperforms the standard one as redundancies are pruned. Our approach has been applied to discover typical patterns of information diffusion in an online social network. Analyses revealed the formation mechanisms of different patterns. (shrink)
