On an influential account, chaos is explained in terms of random behaviour; and random behaviour in turn is explained in terms of having positive Kolmogorov-Sinai entropy (KSE). Though intuitively plausible, the association of the KSE with random behaviour needs justification since the definition of the KSE does not make reference to any notion that is connected to randomness. I provide this justification for the case of Hamiltonian systems by proving that the KSE is equivalent to a generalized version of (...) Shannon's communication-theoretic entropy under certain plausible assumptions. I then discuss consequences of this equivalence for randomness in chaotic dynamical systems.

In this research work, we formulate the phenomena of the financial system in the fractional framework to describe the complex nature of finance. The basic definitions and ideas of the Caputo-Fabrizio fractional operator are listed. We introduce a novel numerical technique for the dynamical behaviour of our fractional model. The oscillatory and chaotic behaviour of the model is studied with the variation of various input parameters on the model. We have shown that there exists strong oscillatory and chaotic (...) behaviour in the system; moreover, we highlighted the impact of fractional-order parameter on the model. The conditions for the local complex behaviour of the system are analyzed with the impact of certain parameters on the macroeconomic. Our findings suggest that the values of initial conditions, fractional order, and input parameters can lessen the chaos of the proposed financial system. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Chaos and LiteratureCarl Matheson and Evan KirchhoffIChaos theory was the intellectual darling of pop-science writers of the late 1980s. 1 In their eyes, it would provide a new paradigm by which to describe the world, one that liberated scientists from clockwork determinism—or, alternatively, from incomprehensible randomness. In an introductory textbook of the period, Robert Devaney called chaos theory “the third great scientific revolution of the 20th century, along with (...) relativity and quantum mechanics.” Similar attitudes propagated into philosophy; for example, Stephen Kellert argued that an acceptance of chaos theory would involve a reconfiguration of scientific methodology. 2It was in the domain of literary theory, however, that chaos found its most enthusiastic reception in the humanities, and the enthusiasm lives on. Many literary theorists display no hesitation in touting the supposedly revolutionary implications of chaos science. Katherine Hayles, the chief among them, argues that because the concept of order has undergone a “radical reevaluation” in recent decades, “textuality is conceived in new ways within critical theory and literature, and new kinds of phenomena are coming to the fore within an emerging field known as the science of chaos” (CO, p. 1). She infers that the new “paradigm of orderly disorder” (CB, p. xiii) represented by chaos theory signifies a conceptual revolution in modern culture as a whole. 3 She attempts to establish a parallel between chaos theory and various poststructuralist philosophical positions, including those of Derrida and Foucault, claiming that this new paradigm “may well prove to be as important to the second half of the century as the field concept was to [End Page 28] the first half” (CB, p. xiii), and that chaos may soon be “on a par with evolution, relativity, and quantum mechanics in its impact on the culture” (CO, p. 4). Other theorists make claims for the interpretive power of chaos; according to William Demastes, “chaos theory can help in comprehending several paths that the theatre has followed since the inception of postmodernism” (p. 242). 4 By a conservative estimate, over fifty papers have been published which link chaos theory to literature or literary theory. Clearly, the idea that chaos theory has application outside of science is not restricted to one or two over-eager humanists.In this essay, we wish to address some of the claims which concern the relationship between chaos science and the study of literature. Three such claims are:a. There are significant similarities between the science of chaos, contemporary literary theory, and/or philosophy.b. We can trace a common etiology for chaos theory and poststructuralist criticism. The two are so intimately related that they are really different formulations of a common claim, as filtered through two different fields.c. The science of chaos can help us interpret and understand specific literary works, and perhaps contemporary literature in general.However, before assessing the relationship between chaos and literature, we will briefly introduce chaos theory itself and demonstrate that even a minimal understanding is sufficient to undercut the supposed revolutionary significance of chaos theory. 5IIChaotic systems are deterministic: an exact description of a system at any given time, together with the laws of nature that apply to it, will entail the entire future behavior of the system. In this sense, chaotic systems form a subclass of classical systems (and are to be distinguished from quantum systems, which are indeterministic). However, chaotic systems differ from the systems studied throughout most of the history of science in two major ways. First, the differential equations used to model them are nonlinear, while the history of mathematical physics is largely devoted to a treatment of linear differential equations. Technical issues aside, the ramifications of nonlinearity are: (i) equations which are impossible to solve using the general strategies designed for [End Page 29] linear equations; and consequently (ii) the need for solutions by methods of numerical approximation, generally performed on a computer. Second, chaotic systems exhibit a feature known as “sensitive dependence”—or, more colorfully, as “the butterfly effect,” a figure of speech intended to evoke the worry that our long-term forecasts of the weather can be hopelessly disrupted by the atmospheric fluctuations due to a single butterfly...

This is the first work to apply complex systems science to the psychological interplay of order and chaos. The author draws on thought from a wide range of disciplines-both conventional and unorthodox-to address such questions as the nature of consciousness, the relation between mind and reality, and the justification of belief systems. The material should provoke thought among systems scientists, theoretical psychologists, artificial intelligence researchers, and philosophers.

This article deals with the control of chaos on the convective motion in a ferrofluid filled in a rotating porous medium and under the helical force effect. We performed a truncated expansion of Galerkin and found the Lorenz-type model which described the system. The dynamical system is characterized using appropriate and subsequent criteria. We noticed that the system presents regular and chaotic behaviors according to the parameters at present. A considerable reduction of the chaotic domain is noticed with (...) the increase of the intensity of the helical force and of the Darcy number, thus making it possible to delay the heat transfer in the system. The increase in the viscosity ratio and the Taylor number widen the chaotic domain leading to an acceleration of the heat transfer in the system. (shrink)

New aspects of spectral fluctuations of (quantum) chaotic and diffusive systems are considered, namely autocorrelations of the spacing between consecutive levels or spacing autocovariances. They can be viewed as a discretized two point correlation function. Their behavior results from two different contributions. One corresponds to (universal) random matrix eigenvalue fluctuations, the other to diffusive or chaotic characteristics of the corresponding classical motion. A closed formula expressing spacing autocovariances in terms of classical dynamical zeta functions, including the (...) Perron–Frobenius operator, is derived. It leads to a simple interpretation in terms of classical resonances. The theory is applied to zeros of the Riemann zeta function. A striking correspondence between the associated classical dynamical zeta functions and the Riemann zeta itself is found. This induces a resurgence phenomenon where the lowest Riemann zeros appear replicated an infinite number of times as resonances and sub-resonances in the spacing autocovariances. The theoretical results are confirmed by existing “data.” The present work further extends the already well known semiclassical interpretation of properties of Riemann zeros. (shrink)

In this paper, we investigate the ultimate bound set and positively invariant set of a 3D Lorenz-like chaotic system, which is different from the well-known Lorenz system, Rössler system, Chen system, Lü system, and even Lorenz system family. Furthermore, we investigate the global exponential attractive set of this system via the Lyapunov function method. The rate of the trajectories going from the exterior of the globally exponential attractive set to the interior of the globally exponential attractive set is also (...) obtained for all the positive parameters values a,b,c. The innovation of this paper is that our approach to construct the ultimate bounded and globally exponential attractivity sets assumes that the corresponding sets depend on some artificial parameters ; that is, for the fixed parameters of the system, we have a series of sets depending on λ and m. The results contain the known result as a special case for the fixed λ and m. The efficiency of the scheme is shown numerically. The theoretical results may find wide applications in chaos control and chaos synchronization. (shrink)

Chaos theory is a rapidly growing field. As a technical term, chaos refers to deterministic but unpredictable processes being sensitively dependent upon initial conditions. Neurobiological models and experimental results are very complicated and some research groups have tried to pursue the neuronal chaos. Babloyantz's group has studied the fractal dimension (d) of electroencephalograms (EEG) in various physiological and pathological states. From deep sleep (d=4) to full awakening (d>8), a hierarchy of strange attractors paralles the hierarchy of states of consciousness. In (...) epilepsy (petit mal), despite the turbulent aspect of a seizure, the attractor dimension was near to 2. In Creutzfeld-Jacob disease, the regular EEG activity corresponded to an attractor dimension less than the one measured in deep sleep. Is it healthy to be chaotic? An active desynchronisation could be favourable to a physiological system. Rapp's group reported variations of fractal dimension according to particular tasks. During a mental arithmetic task, this dimension increased. In another task, a P300 fractal index decreased when a target was identified. It is clear that the EEG is not representing noise. Its underlying dynamics depends on only a few degrees of freedom despite yet it is difficult to compute accurately the relevant parameters.What is the cognitive role of such a chaotic dynamics? Freeman has studied the olfactory bulb in rabbits and rats for 15 years. Multi-electrode recordings of a few mm2 showed a chaotic hierarchy from deep anaesthesia to alert state. When an animal identified a previously learned odour, the fractal dimension of the dynamics dropped off (near limit cycles). The chaotic activity corresponding to an alert-and-waiting state seems to be a field of all possibilities and a focused activity corresponds to a reduction of the attractor in state space. For a couple of years, Freeman has developed a model of the olfactory bulb-cortex system. The behaviour of the simple model without learning was quite similar to the real behaviour and a model with learning is developed. (shrink)

This important study makes a convincing case for its thesis that the dramatic form of Shakespeare's plays corresponds to that of a natural system evolving to a more complex state while undergoing symmetry breaking. Drawing upon such key concepts of chaos theory as "global agency and self-similarity," the book constructs a methodology which illuminates many problematic aspects of agency in the selected comedies, tragedies, and histories it examines. Each of these genres is shown to reflect the paradoxical dynamics of a (...) chaotic system. This fresh -systems perspective- offers a serious challenge to the structuralist assumptions underlying many current literary approaches.". (shrink)

Chaos, once considered antithetical to scientific law and order, is presently the subject of a vigorous and progressive scientific research program. "Chaos" as it is used in current scientific literature is a technical term: it refers to stochastic behavior generated by deterministic systems. This behavior has appeared in models of a wide range of phenomena including atmospheric patterns, population dynamics, celestial motion, heartbeat rhythms, turbulent fluids, chemical reactions and social structures. In general, chaos arises in the (...) nonlinear dynamics of complex systems. Grebogi, Ott and Yorke reflect the sentiment of the scientific community when they state that chaotic nonlinear dynamics has "fundamental implications." This dissertation explores these results in a philosophic context. ;The research is organized as follows: The Context of Science. Scientific results are achieved in and make sense in the practical context of research which includes both experiment and theory. Drawing on the work of Dyke, Galison, Garfinkel and Hacking, a philosophic context is described which more accurately reflects the significance of scientific results than do the contexts of discovery and justification. Models. Chaos theory is constituted by a family of numerical models. In this chapter, Giere's account of modeling is extended to both bio-medical and numerical models. Chaos in Scientific Models. This is a rather lengthy primer of chaos theory that is, although technically accurate, accessible to nonspecialists. It constitutes a road map for the primary literature on chaos. Chaos and Prediction. Chaos theory shows a limit of our science, namely, chaotic systems are deterministic yet unpredictable in the long run. The chapter includes a discussion of scientific determinism following Popper and, it concludes by providing evidence against the laplacian claim that deterministic systems are predictable. Chaos and Complexity. This shows what contribution chaos theory makes toward answering the challenge of organized complexity articulated by Weaver. It discusses attempts to characterize complexity and shows how the results of chaos theory can help. I draw on the work of Abraham, Arecchi, Atlan, Chaitin, Eckmann, Peacocke, Rosen, Ruelle, and others. Chaos theory provides a thoroughly nonvitalistic framework for understanding dynamical complexity in organic, as well as inorganic, systems. (shrink)

Approach–avoidance theories describe the major systems that motivate behaviours in reaction to classes of appetitive (rewarding) and aversive (punishing) stimuli. The literature points to two major “avoidance” systems, one related to pure avoidance and escape of aversive stimuli, and a second, to behavioural inhibition induced by the detection of goal conflict (in addition, there is evidence for nonaffective behavioural constraint). A third major system, responsible for approach behaviour, is reactive to appetitive stimuli, and has several subcomponents. A (...) number of combined effects of these systems are outlined. Finally, the hierarchical nature of behavioural control is delineated, including the role played by conscious awareness in behavioural inhibition. (shrink)

Using the concepts of chaotic dynamical systems, we present an interpretation of dynamic neural activity found in cortical and subcortical areas. The discovery of chaotic itinerancy in high-dimensional dynamical systems with and without a noise term has motivated a new interpretation of this dynamic neural activity, cast in terms of the high-dimensional transitory dynamics among “exotic” attractors. This interpretation is quite different from the conventional one, cast in terms of simple behavior on low-dimensional attractors. Skarda (...) and Freeman (1987) presented evidence in support of the conclusion that animals cannot memorize odor without chaotic activity of neuron populations. Following their work, we study the role of chaotic dynamics in biological information processing, perception, and memory. We propose a new coding scheme of information in chaos-driven contracting systems we refer to as Cantor coding. Since these systems are found in the hippocampal formation and also in the olfactory system, the proposed coding scheme should be of biological significance. Based on these intensive studies, a hypothesis regarding the formation of episodic memory is given. Key Words: Cantor coding; chaotic itinerancy; dynamic aspects of the brain; dynamic associative memory; episodic memory; high-dimensional dynamical systems; SCND attractors. (shrink)

The literature on deep brain stimulation (DBS) and adaptive DBS (aDBS) raises concerns that these technologies may affect personality, mood, and behavior. We conducted semi-structured interviews with researchers (n = 23) involved in developing next-generation DBS systems, exploring their perspectives on ethics and policy topics including whether DBS/aDBS can cause such changes. The majority of researchers reported being aware of personality, mood, or behavioral (PMB) changes in recipients of DBS/aDBS. Researchers offered varying estimates of the frequency of (...) PMB changes. A smaller majority reported changes in personality specifically. Some expressed reservations about the scientific status of the term ‘personality,’ while others used it freely. Most researchers discussed negative PMB changes, but a majority said that DBS/aDBS can also result in positive changes. Several researchers viewed positive PMB changes as part of the therapeutic goal in psychiatric applications of DBS/aDBS. Finally, several discussed potential causes of PMB changes other than the device itself. (shrink)

Purpose – The purpose of this study is to investigate the reasons behind unethical behaviour in the Australian Information and Communications Technology workplace. Design/methodology/approach – The study employed a qualitative research methodology. A total of 43 ICT professionals were interviewed during the month of February 2014 in six Australian capital cities. All interviews were conducted face-to-face and followed a semi-structured interviewing format utilising open-end questions and further probing questions. The purposive sample represented ICT professionals from large and small organisations, government (...) and private sector, different geographic locations, ages, genders, types of jobs and employment experience. Data analysis was completed with the help of QSR NVivo 10, a software package for managing qualitative data. Findings – Of the 25 reasons identified for unethical behaviour in ICT workplaces, 30 per cent of participants agreed on five major ones: pressure, bad management, greed, lack of respect towards ICT and communication issues. Practical implications – By focussing on the reasons behind unethical behaviour in the Australian ICT workplace, this article helps those identifying strategies for dealing with unprofessional behaviour to take into account the root causes of unprofessional behaviour. Originality/value – There is hardly any literature on reasons for unethical behaviour in the ICT workplaces. This article seeks to address this imbalance in the literature. Also, integrity systems in ICT are a new focus in collective, organisational ethics. Identification of and resolving unethical ICT workplace practice is an innovative contribution to the literature.

This text addresses the problems of complex systems in understanding natural phenomena and the behaviour of systems related to human activity, from a science and humanities perspective. It discusses molecular behaviour and structures, and offers examples of ecological and environmental modelling.

This text explores how we understand living and other complex systems. The conventional basis of understanding rests on abstract general theories, but this book proposes conceptual continuity as a new means of comparing systems of divergent complexity and resolving problems in complex systems.

An organization's management control system can play an important role in influencing ethical behavior among employees. In this paper a theoretical framework of control is developed by linking various ethics related control mechanisms reported in the literature to the primary components of a management control system. In addition, the findings of a survey of the Financial Post's Top 1 000 Canadian industrial and service companies are reported. The survey investigated organizations' use of ethical codes of conduct, whistleblowing (...) class='Hi'>systems, ethics committees, judiciary boards, employee training in ethics, and ethics focused corporate governance and reward systems. The findings indicate that ethics related control mechanisms, particularly codes of conduct, are being used by a good number of organizations. However, closer analysis of the data suggests that many companies may only be paying lip service to the importance of promoting ethical behavior. (shrink)

The behavior of some systems is non-computable in a precise new sense. One infamous problem is that of the stability of the solar system: Given the initial positions and velocities of several mutually gravitating bodies, will any eventually collide or be thrown off to infinity? Many have made vague suggestions that this and similar problems are undecidable: no finite procedure can reliably determine whether a given configuration will eventually prove unstable. But taken in the most natural way, this (...) is trivial. The state of a system corresponds to a point in a continuous space, and virtually no set of points in space is strictly decidable. A new, more pragmatic concept is therefore introduced: a set is decidable up to measure zero (d.m.z.) if there is a procedure to decide whether a point is in that set and it only fails on some points that form a set of zero volume. This is motivated by the intuitive correspondence between volume and probability: we can ignore a zero-volume set of states because the state of an arbitrary system almost certainly will not fall in that set. D.m.z. is also closer to the intuition of decidability than other notions in the literature, which are either less strict or apply only to special sets, like closed sets. Certain complicated sets are not d.m.z., most remarkably including the set of known stable orbits for planetary systems (the KAM tori). This suggests that the stability problem is indeed undecidable in the precise sense of d.m.z. Carefully extending decidability concepts from idealized models to actual systems, we see that even deterministic aspects of physical behavior can be undecidable in a clear and significant sense.

This paper is expected to introduce a novel memductor-based chaotic system. The local dynamical entities, such as the basic dynamical behavior, the divergence, the stability of equilibrium set, and the Lyapunov exponent, are all investigated analytically and numerically to reveal the dynamic characteristics of the new memductor-based chaotic system as the system parameters and the initial state of memristor change. Subsequently, an active control method is derived to study the synchronous stability of the novel memductor-based chaotic (...) system through making the synchronization error system asymptotically stable at the origin. Further to these, a memductor-based chaotic circuit is designed, realized, and applied to construct a new memductor-based secure communication circuit by employing the basic electronic components and memristor. Furthermore, the design principle of the memductor-based chaotic circuit is thoroughly analyzed and the concept of “the memductor-based chaotic circuit defect quantification index” is proposed for the first time to verify whether the chaotic output is consistent with the mathematical model. A good qualitative agreement is shown between the simulations and the experimental validation results. (shrink)

A growing literature looks at how the design of the electoral system shapes the voting behavior of politicians in parliaments. Existing research tends to confirm that in mixed-member systems the politicians elected in the single-member districts are more likely to vote against their parties than the politicians elected on the party lists. However, we find that in South Korea, the members of the Korean National Assembly who were elected on PR lists are more likely to vote against (...) their party leadership than the members elected in single-member districts (SMDs). This counterintuitive behavior stems from the particular structure of candidate selection and politicians' career paths. This suggests that any theory of how electoral systems shape individual parliamentary behavior needs to look beyond the opportunities provided by the electoral rules for voters to reward or punish individual politicians (as opposed to parties), to the structure of candidate selection inside parties and the related career paths of politicians.

In a previous essay I argued that quantum chaos cannot be exhibited in models of quantum systems within von Neumann's mathematical framework for quantum mechanics, and that it can be exhibited in models within Dirac's formal framework. In this essay, the negative thesis concerning von Neumann's framework is elaborated further by extending it to the case of Hamiltonian operators having a continuous spectrum. The positive thesis concerning Dirac's formal framework is also elaborated further by constructing a chaotic model (...) of an open quantum system in which an entropy measure is shown to approach its maximum value as time goes to infinity. Having such an entropy measure is a characteristic that is closely connected to chaotic behavior in phase space models of classical systems. (shrink)

The literature has suggested that to understand the diffusion of unethical conduct in the workplace, it is important to investigate the underlying processes sustaining engagement in misbehaviour and to study what occurs during vocational education. Drawing on social-cognitive theory, in this study, we longitudinally examined the role of two opposite dimensions of the self-regulatory moral system, regulatory self-efficacy and moral disengagement, in influencing academic cheating behaviour. In addition, in line with the theories highlighting the bidirectional relationship between cognitive processes (...) and behaviour, we aimed to also examine the reciprocal influence of behaviour on these dimensions over time. Overall, no previous studies have examined the longitudinal interplay between these variables. The sample included 866 nursing students who were assessed three times annually from the beginning of their vocational education. The findings from a cross-lagged model confirmed that regulatory self-efficacy and moral disengagement have opposite influences on cheating behaviour, that regulatory self-efficacy negatively influences not only the engagement in misconduct but also the justification mechanisms that allow the divorce between moral standards and action, and that moral disengagement and cheating behaviour reciprocally support each other over time. Specifically, not only did moral disengagement influence cheating behaviour even when controlling for its prior levels, but also cheating behaviour affected moral disengagement one year later, controlling for its prior levels. These findings suggest that recourse to wrongdoing could gradually lead to further normalising this kind of behaviour and morally desensitising individuals to misconduct. (shrink)

Bangladesh is aspiring to achieve universal health coverage by 2030. In this regard, quality and efficient healthcare delivery have been regarded as a major challenge. Proper management of employees is crucial for service organizations like healthcare because in healthcare employees provide life saving services which make them unique from other non-health professionals. They directly interface with the patients or service seekers who make evaluative judgment of the quality of service delivered by the employees. Therefore, it is important that healthcare organizations (...) (both public and private) comprehend specific organizational factors and issues that influence employee’s attitudes and behaviors, which ultimately affect their service behaviour at work. Drawing from the organizational justice principles and other management theories, this article presents a conceptual framework and a set of hypotheses regarding the relationships among distributive justice, procedural justice, interactional justice, employee’s citizenship behaviour, role prescribed behaviour and counterproductive behaviour for the healthcare organizations in Bangladesh. The purpose is to assist the policy makers and service providers in identifying desirable human resource management practices that healthcare organizations in Bangladesh should seek and engage in and at the same time, avoid undesirable practices in order to maintain optimum level of employee commitment, and citizenship behavior essential for ensuring quality and efficient service delivery to the communities. This article is ‘theoretical’ but it has practical implications for the policy makers and service providers who are directly involved with service delivery system. It is also expected that the paper enriches the health service delivery literature and also advocates focusing on justice perspectives particularly in Bangladesh. (shrink)

In 1973, Nickles identified two senses in which the term `reduction' is used to describe the relationship between physical theories: namely, the sense based on Nagel's seminal account of reduction in the sciences, and the sense that seeks to extract one physical theory as a mathematical limit of another. These two approaches have since been the focus of most literature on the subject, as evidenced by recent work of Batterman and Butterfield, among others. In this paper, I discuss a (...) third sense in which one physical theory may be said to reduce to another. This approach, which I call `dynamical systems reduction,' concerns the reduction of individual models of physical theories rather than the wholesale reduction of entire theories, and specifically reduction between models that can be formulated as dynamical systems. DS reduction is based on the requirement that there exist a function from the state space of the low-level model to that of the high-level model that satisfies certain general constraints and thereby serves to identify quantities in the low-level model that mimic the behavior of those in the high-level model - but typically only when restricted to a certain domain of parameters and states within the low-level model. I discuss the relationship of this account of reduction to the Nagelian and limit-based accounts, arguing that it is distinct from both but exhibits strong parallels with a particular version of Nagelian reduction, and that the domain restrictions employed by the DS approach may, but need not, be specified in a manner characteristic of the limit-based approach. Finally, I consider some limitations of the account of reduction that I propose and suggest ways in which it might be generalised. I offer a simple, idealised example to illustrate application of this approach; a series of more realistic case studies of DS reduction is presented in another paper. (shrink)

This paper establishes a model on the upstream and downstream relationship among private enterprises, provincial and local officials, and the central government in the real estate market using the population ecology theory of mutual relations among individual species from the perspective of business ecosystem. A dynamic model is introduced and the complex dynamical behaviors of such a predator-prey model are investigated by means of numerical simulation. The local stability conditions and complex dynamics are investigated, and the existence of chaos is (...) discussed in the sense of Marotto theorem; bifurcation diagrams, Lyapunov exponents, sensitivity analysis for initial values, and time history figure of the system are mapped out and discussed. This shows that there are two routes to complicated dynamics, one of which is the cascade of flip bifurcations resulting in periodic cycles, and the other one is Neimark-Sacker bifurcation which produces attractive invariant closed curves. We arrive at conclusions that the phenomenon of chaos is harmful to private enterprises, and unstable behavior is often unfavorable. Thus, linear feedback control is applied to drive the model to a stable state when the system exhibits chaotic behaviors, achieving the goal of eliminating the negative effects to a large extent.

Organizational culture and employee conduct in financial institutions are coming under increasing scrutiny by regulators who seek to identify the underlying sources of unethical behavior. The literature on ethics in the workplace has often emphasized the importance of the alignment of systems and processes with organizational values and the role of the leader in creating an ethical culture. Less is known about how individual employees experience the ethical decision-making process, especially in complex and high-risk business environments where (...) there are discrepancies between an organization’s formal ethical standards and its informal practices. This article combines ethical decision-making models with key concepts from organization and adult learning theories to develop a deeper and more nuanced view of how individuals in financial institutions deal with ethical issues that arise in their daily work. Eight practical ideas are formulated to help financial institutions narrow the gap between formal ethical standards and actual practices and develop a culture that promotes ethical behavior: challenging authority, creating opportunities for discourse, valuing positive emotion, making time for reflection, rewarding ethical behavior, strengthening escalation processes, eliciting feedback, and establishing a learning culture.

A detailed critique of some quite radical proposals of the Prigogine school is given.

The analogy they want to draw with quantum mechanics is not sufficiently close to (...) support their most radical conclusion. (shrink)

Organizations have increasingly relied on team-based reward systems to boost productivity and foster collaboration. Drawing on the literature on ethics and justice as well as appraisal theories of emotion, we examine how team-based reward systems can have an insidious side effect: They increase the likelihood that employees remain silent when observing a team member engage in unethical behavior. Across four studies adopting different methods, measures, and samples, we found consistent evidence that people are less likely to (...) report (i.e., speak up or provide anonymous feedback about) a team member’s unethical behavior in team-based than in individual-based reward systems. Furthermore, our research reveals that this effect is primarily driven by a decrease in the experience of moral anger, which subsequently leads to a decreased likelihood of reporting unethical behavior when it benefits the team rather than the individual. We do not find support for perceived indirect benefit or envy as alternative explanations, suggesting that the decision to report a team member’s unethical behavior is not driven by calculative and selfish motives, but by moral motives. Finally, we establish that the effect is contingent on the observer and the perpetrator being members of the same team; it dissipates when the observer and the perpetrator are part of different teams. Our work contributes to research on reward systems and business ethics and provides practical implications for human resource practices. (shrink)

Recently, megastable systems have grabbed many researchers’ interests in the area of nonlinear dynamics and chaotic systems. In this paper, the oscillatory terms’ coefficients of the simplest megastable oscillator are forced to blink in time. The forced system can generate an infinitive number of hidden attractors without changing parameters. The behavior of these hidden attractors can be chaotic, tori, and limit cycle. The attractors’ topology of the system seems unique and looks like picture frames. Besides, (...) the existence of different coexisting attractors with different kinds of behaviors reflects the system's high sensitivity. Using the sample entropy algorithm, the system’s complexity for different initial values is assessed. In addition, the circuit of the introduced forced system is designed, and the possibility of implicating the system with analog elements is investigated. (shrink)

Investigating the causes of unethical behaviors in academia, such as scientific misconduct, has become a highly important research subject. The current performance measurement practices (e.g., equating research performance with the number of publications in top-tier journals) are frequently referred to as being responsible for scientists’ unethical behaviors. We conducted qualitative semi-structured interviews with different stakeholders of the higher education system (e.g., professors and policy makers; N = 43) to analyze the influence of performance measurement on scientists’ behavior. We followed (...) a three-step coding procedure and found (1) that the participants described a variety of positive behavioral consequences (e.g., higher productivity) but mainly negative behavioral consequences (e.g., questionable publishing practices) of current performance measurement practices in academia; (2) that scientists’ behavior can be described as gaming performance measurement (i.e., achieving performance goals by reducing performance quality and focusing on those tasks that are measured); and (3) that gaming performance measurement shares the same characteristics as deviant workplace behavior (i.e., a voluntary violation of organizational norms that harms the university). We discuss that gaming performance measurement has not been considered as a type of deviant workplace behavior in the previous literature. Furthermore, we draw from research on deviant workplace behavior and goal setting to discuss psychological processes that may underlie gaming performance measurement. Our results indicate the importance of connecting literature on deviant workplace behavior and goal setting to advance our understanding of gaming performance measurement. (shrink)

We demonstrate by use of a simple one-dimensional model of a square barrier imbedded in an infinite potential well that decoherence is enhanced by chaotic-like behavior. We, moreover, show that the transition h→0 is singular. Finally it is argued that the time scale on which decoherence occurs depends, on the degree of complexity of the underlying quantum mechanical system, i.e., more complex systems decohere relatively faster than less complex ones.

Recent discussions in the philosophy of science have devoted considerable attention to the analysis of conceptual issues relating to the methodology of explanation and prediction in the sciences. Part of this literature has been devoted to clarifying the very ideas of explanation and prediction. But the discussion has also ranged over various related topics, including the status of laws to be used for explanatory and predictive purposes, the logical interrelationships between explanatory and predictive reasonings, the differences in the strategy (...) of explanatory argumentation in different branches of science, the nature and possibility of teleological explanation, etc. The aim of the present article is to examine the issues involved in such questions from the specialized perspective afforded by one particular kind of physical systems--namely, systems, here to be characterized as discrete state systems, whose behavior has been studied extensively in the scientific literature under the general heading of Markov chains. These systems have been chosen as our focus because their behavior over time can be analyzed at once with great ease and with extraordinary precision. (shrink)

This research synthesizes social exchange, organizational culture, and social identity theories to explore the boundary conditions of the relationship between high-performance work systems and employee organizational citizenship behavior. In particular, it draws on the China-specific management context. In this country, in spite of the wide use of a long-term-oriented and loose-control-focused Western-styled strategic human resource management model, a short-term-focused and tight-control-oriented error aversion culture is still popular. The study uses multi-source individual-level survey data in a large state-owned enterprise (...) to test the hypotheses. It is found that employee-experienced, Western-styled high-performance work systems positively impact a China-specific employee’s organizational citizenship behavior, and the—joint—moderation effects of employee-perceived error aversion culture and organizational identification are significant. The research findings deepen the understanding of the HRM-OCB relationship by demonstrating that culture and identity can jointly adjust the effects of HRM on OCB. The findings also challenge an established argument in the HRM-OCB literature that compatibility between employees’ personalities and organizational values – organizational identification – can enhance OCB.

Heinrichs (bio)In considering the specific issues raised by these three very thoughtful commentaries, it is helpful to reflect on the status of a theory or model for a specifically clinical discipline—what is it trying to accomplish and how might it proceed to do so? Kellert (2005) sees my proposal in terms of "borrowed knowledge"—the metaphorical application of a theory established in one field of (...) inquiry to another field—and views my application of chaos theory as a "nonliteral use of knowledge from the natural sciences" (p. 239). He likens it to attempts to explore consequences of relativity theory or quantum mechanics for areas other than those for which they were developed. He notes the rhetorical functions—including appeal to the disciplinary prestige of natural science—of such metaphorical borrowings.Although clearly there are significant metaphorical aspects at work here, there are at least two factors that distinguish this model from, say, the metaphorical application of quantum mechanics to a field other than subatomic physics. First, quantum mechanics purports to say something specific about the behavior of the subatomic world. Its development is wed to that specific content area. On the other hand, nonlinear dynamics, including chaos theory, is a formal mathematical model intending to characterize the behavior of any system of elements that possess certain formal relational properties. It does not start out as field or discipline specific. In fact it is not uniquely tied to the natural sciences at all, beyond the fact that it may be easier to obtain the sort of detailed repeated measures needed to demonstrate chaotic behavior in physical systems. So it is not just a question of whether chaos theory is a useful intuitive device for thinking freshly about clinical psychiatry. Rather, it is the quite literal and nonmetaphorical question as to whether some of the observable aspects of persons that are relevant to their psychiatric care behave chaotically, and if so what are the implications.Now it is quite true that direct, mathematically rigorous demonstrations of chaos in clinically relevant data sets is currently limited. In fact, one hoped for consequence of presenting this model is to encourage just such studies, and I suggest several promising directions for doing so. However, there are good reasons for thinking the presence of such chaotic behavior to be likely, and this relates to the notion of a clinical theory.One of the consequences of what Globus (2005) calls "triumphalist biological psychiatry" (p. 229) is the frequent assumption that the model or paradigm of psychiatry—an applied clinical practice, a techne—is synonymous with the paradigm of neuroscience—a basic science or episteme. This is clearly not so for many reasons, including the fact that the former has to incorporate the comprehensive treatment of discrete individuals in a way that the latter does not. Yet the respective theories are related more than metaphorically. [End Page 243] The paradigms of neuroscience and those of other relevant basic sciences, such as psychology, substantially inform the clinical paradigm and the clinical model must be at least compatible with those of the relevant basic sciences. Thus, it is reasonable to assume that if chaotic processes are demonstrable in the nervous system, for which significant evidence already exists, there is good reason to expect them to be reflected in clinically relevant domains. The clinical paradigm should make room for it and its consequences, rather than thinking within an outmoded neuroscience model that makes no room for the implications of nonlinear dynamics. And when this generates a picture more compatible than the old model with our usual sense of what it is to be human, the odds that we are on to something is further enhanced. Of course until such time that enough clinical research based on this model is completed, considerable speculation—indeed aided by metaphorical devices—is involved in generating a concrete sense of how the model would be applied to specific clinical problems, such as the treatment of depressed persons.One clear task of the clinical paradigm is the methodologic integration of interventions growing out of different informing basic sciences. Because chaotic modeling can be applied across various content domains and... (shrink)

Various organizational factors reported in the hitherto literature affect individual behaviour within a company. In this paper, we conduct a literature review thereof, and propose a notion of the “Organizational Moral Structure” defined as a comprehensive framework of interrelated organizational factors that condition, incite or influence good or bad moral behaviour of individuals within the organization. Drawing from a wide bibliographical review and our own reflection on recent business scandals, we identify seven constituents of the “Organizational Moral Structure”: (...) 1) leader’s values and character, 2) vision and exercise of power, 3) corporate control systems, 4) internal network of influence, 5) organizational culture, 6) internal and competitive pressures, and 7) external influences. The “Organizational Moral Structure” is proposed as a reflective framework for humanistic management and as an invitation to further research in this field. We provide recommendations on how a manager oriented towards humanistic management can use the OMS to secure and promote well-being and dignity of company’s employees. (shrink)

In order for artificial intelligent systems to interact naturally with human users, they need to be able to learn from human instructions when actions should be imitated. Human tutoring will typically consist of action demonstrations accompanied by speech. In the following, the characteristics of human tutoring during action demonstration will be examined. A special focus will be put on the distinction between two kinds of motion events: path-oriented actions and manner-oriented actions. Such a distinction is inspired by the (...) class='Hi'>literature pertaining to cognitive linguistics, which indicates that the human conceptual system can distinguish these two distinct types of motion. These two kinds of actions are described in language by more path-oriented or more manner-oriented utterances. In path-oriented utterances, the source, trajectory, or goal is emphasized, whereas in manner-oriented utterances the medium, velocity, or means of motion are highlighted. We examined a video corpus of adult–child interactions comprised of three age groups of children—pre-lexical, early lexical, and lexical—and two different tasks, one emphasizing manner more strongly and one emphasizing path more strongly. We analyzed the language and motion of the caregiver and the gazing behavior of the child to highlight the differences between the tutoring and the acquisition of the manner and path concepts. The results suggest that age is an important factor in the development of these action categories. The analysis of this corpus has also been exploited to develop an intelligent robotic behavior—the tutoring spotter system—able to emulate children's behaviors in a tutoring situation, with the aim of evoking in human subjects a natural and effective behavior in teaching to a robot. The findings related to the development of manner and path concepts have been used to implement new effective feedback strategies in the tutoring spotter system, which should provide improvements in human–robot interaction.

To sustainably govern a Social-Ecological System (SES), both the academic literature and practitioners recommend involving a broad range of actors—public or private—from the territory in question. Nonetheless, the presence of actors in collaborative SES governance processes is not a given. Since this presence requires time and energy without direct personal reward, it depends on the actors’ likelihood to embrace a stewardship role, which in turn depends on their relationship with their biophysical and social contexts. This paper studies the role (...) played by actors’ places of residence in their stewardship behavior in collaborative SES governance. To this end, we analyze the attendance patterns of over 600 members of a French River Basin Committee over 26 years, to shed light on the biophysical determinants. We find that individuals’ biophysical experience plays a critical role in motivating ‘place stewardship’ behavior—especially for key groups of actors such as farmers. We discuss the challenges that place stewardship poses for SESs and outline measures for fostering broader SES stewardship. (shrink)

In this ground-breaking work, Allan Combs presents a wide-ranging survey of the nature and origins of consciousness research, viewing consciousness as a dynamic and self-organizing process with evolutionary potential. Combs reviews the work of evolutionary theorists such as Pierre Teilhard de Chardin, Ken Wilber, Jean Gebser, and Sri Aurobindo. What emerges is a fascinating study of consciousness that discloses itself as a rich and ongoing act of self-creation, poised at the edge of chaos between past and future.

High-performance work systems -performance research has dominated innovative human resource management studies for two decades. However, mainstream HPWS research has paid little attention to employees’ perceptions of HPWS, or to the relationship between HPWS and corporate social performance. The influence of CSP on employee outcomes such as organizational commitment and organizational citizenship behaviour has thus been similarly neglected. This paper seeks to investigate these missing links in literature using data collected from a sample of 700 employees in China. (...) The findings demonstrate that HPWS is positively related to HPWS satisfaction and employees’ perceptions of CSP. HPWS satisfaction fully mediates the relationship between HPWS and employees’ affective commitment. There are multiple mediators between HPWS and OCB, indicating more complicated mechanisms through which HPWS leads to desired HR outcomes. Employees’ perceived CSP has a significant influence on HPWS satisfaction, AC and OCB, suggesting firms should place a premium on achieving a reputation as being socially responsible. (shrink)

In this book, after discussing the fundamental problems of current science and other philosophic concepts, beginning with controversies between Heraclitus and Parmenides, Ilya Prigogine launches into a message of great hope: the future has not been determined. Contrary to globalisation and the apparent contemporary mass culture society, individual behaviour is beginning to increasingly become the key factor which governs the evolution of both the world and society as a whole. It is a message that challenges existing widespread views, implicitly or (...) explicitly, through mass communication, moreover the importance of the individual's actions implies a reflection of each person on the responsibilities that each one assumes when taking or acting upon a decision. This responsibility is associated with the freedom of thought as well as a critical analysis of fashions, customs, preconceived ideas, and ideologies, externally imposed: exactly contrary to the ideas of those who wish us to be "perfect consumers" in a world dominated only by monetary wealth. Challenging this drive towards the elimination of freedom of though in the individual is now imperative if we are to save man and his planet from catastrophe which seems to be ever imminent and (unfortunately) irreversible. This last book of Ilya Prigogine provides a small, disputable, but nonetheless valuable contribution towards that end. (shrink)

In the present article, we review the theory and research on religious deconversion with a focus on adolescence and young adulthood. First, we present the relevant terminology (e.g. religious deconversion, religious disaffiliation, and religious deidentification) and statistical trends (e.g. the prevalence of religious Nones and Dones). We define religious deconversion as any movement away from religion. Religiosity decreases across adolescence and into young adulthood, and these developmental periods also have heightened rates of religious deidentification, at least in many Western cultures. (...) Second, we review the theory and research on processes, predictors, and outcomes of religious deconversion. Deconversion is discussed both in terms of individuals becoming less religious and possibly deidentifying from religion. In terms of processes of deconversion, we discuss various theoretical models and self-expressed reasons for deconversion. Religious deconversion tends to progress in phases, often initiated by religious and spiritual struggles. In terms of predictors, we identify predictors at the level of the individual (e.g. demographics, personality, norm-violating behavior, and dimensions of religiosity), family (e.g. parent and family religiosity, family dynamics such as parenting styles, and religious socialization), peers (e.g. peer religiosity and religious conversations with peers), religious communities (e.g. supportiveness, engagement, and dialogue), formal education, and social media. In line with developmental systems perspectives, religious deconversion is a complex and dynamic process involving numerous individual and contextual factors. In terms of outcomes of deconversion, we identify potential individual and relational outcomes that are considered both negative and positive. Finally, we outlined 10 promising future directions for research on religious deconversion. (shrink)
