  1. Leonid Grinin, Andrey Korotayev & Sergey Malkov (2010). A Mathematical Model of Juglar Cycles and the Current Global Crisis. In Leonid Grinin, Peter Herrmann, Andrey Korotayev & Arno Tausch (eds.), History & Mathematics: Processes and Models of Global Dynamics.score: 24.0
    The article presents a verbal and mathematical model of medium-term business cycles (with a characteristic period of 7–11 years) known as Juglar cycles. The model takes into account a number of approaches to the analysis of such cycles; in the meantime it also takes into account some of the authors' own generalizations and additions that are important for understanding the internal logic of the cycle, its variability and its peculiarities in the present-time conditions. The authors argue that (...)

    Recent high-profile corporate scandals are reminiscent of the corporate raider scandals of the 1980s, suggesting that ethical scandals may occur in waves. This article provides a framework for analysis of this question by suggesting that ethical attitudes may be cyclical about long-term secular trends. We provide some empirical evidence from previously published work for the existence of cycles as well as a potential mechanism for their propagation, namely widespread publicity about a particularly salient (...)

    The Condorcet efficiency of a social choice procedure is usually defined as the probability that this procedure coincides with the majority winner (or majority ordering) in random samples, given a majority winner exists (or given the majority ordering is transitive). Consequently, it is in effect a conditional probability that two sample statistics coincide, given certain side conditions. We raise a different issue of Condorcet efficiencies: What is the probability that a social choice procedure applied to a sample matches with the (...)

    It is widely believed that women who live together or who are close friends synchronize their menstrual cycles. We reexamined this phenomenon in two ways. First, we collected data on menstrual cycles from 186 Chinese women living in dorms for over a year. We found that women living in groups did not synchronize their cycles. Second, we reviewed the first study reporting menstrual synchrony. We found that group synchrony in that study was at the level of chance. (...)

  5. Jan Heufer (forthcoming). A Geometric Approach to Revealed Preference Via Hamiltonian Cycles. Theory and Decision:1-13.score: 24.0
    It is shown that a fundamental question of revealed preference theory, namely whether the weak axiom of revealed preference (WARP) implies the strong axiom of revealed preference (SARP), can be reduced to a Hamiltonian cycle problem: A set of bundles allows a preference cycle of irreducible length if and only if the convex monotonic hull of these bundles admits a Hamiltonian cycle. This leads to a new proof to show that preference cycles can be of arbitrary length for more (...)

    While recent studies have shed light on the mechanisms that generate gamma (>40Hz) oscillations, the functional role of these oscillations (if any) is still debated. Here we suggest that the purported mechanism of gamma oscillations (feedback inhibition from local interneurons), coupled with lateral connections implementing “Gestalt” principles of object integration, naturally leads to a decomposition of the visual input into object-based “perceptual cycles”, in which neuron populations representing different objects within the scene will tend to fire at successive (...) of the local gamma oscillation. We describe a simple model of V1 in which such perceptual cycles emerge automatically from the interaction between lateral excitatory connections (linking oriented cells falling along a continuous contour) and fast feedback inhibition (implementing competitive firing and gamma oscillations). Despite its extreme simplicity, the model spontaneously gives rise to perceptual cycles even when faced with natural images. The robustness of the system to parameter variation and to image complexity, together with the paucity of assumptions built in the model, support the hypothesis that perceptual cycles occur in natural vision.

    Mixed-strategy equilibria are typically rather unstable in evolutionary game theory. “Monocyclic” games, such as Rock–Paper–Scissors, have only mixed equilibria, some of which are “stable” in the sense that sequential best replies lead to them; yet, even these games are prone to stable cycles under discrete-time simultaneous best replies, giving an unusual equilibrium-selection problem. This article analyzes such games in a random-utility setting where changing strategies is costly, and the speed of the dynamic is, thus, endogenous. The stochastically stable outcome (...)

    We address three issues regarding the relationship between political party affiliation and returns in the equities markets, as measured by the NYSE Composite Index and its sub-indexes. First, we find a tendency for returns to be greater during Democratic presidential administrations; however, this result is statistically insignificant. Second, we conclude that returns during the last two years of presidential administrations are greater than during the first two years. Third, we examine the relationship between the majority party in each house of (...)

    Across the world, the lives of men and women who are otherwise similarly situated tend to differ from each other systematically. Although gender disparities varywidely within and among regions, women everywhere are disproportionately vulnerable to poverty, abuse and political marginalization. This article proposes thatglobal gender disparities are caused by a network of norms, practices, policies, and institutions that include transnational as well as national elements. These interlaced and interacting factors frequently modify and sometimes even reduce gendered vulnerabilities but their overall (...)

    The themes, problems and challenges of developmental systems theory as described in Cycles of Contingency are discussed. We argue in favor of a robust approach to philosophical and scientific problems of extended heredity and the integration of behavior, development, inheritance, and evolution. Problems with Sterelny's proposal to evaluate inheritance systems using his `Hoyle criteria' are discussed and critically evaluated. Additional support for a developmental systems perspective is sought in evolutionary studies of performance and behavior modulation of fitness.

    This item was published as 'Appendix 3: An Implication of the k-option Condorcet jury mechanism for the probability of cycles' in List and Goodin (2001) http://eprints.lse.ac.uk/705/. Standard results suggest that the probability of cycles should increase as the number of options increases and also as the number of individuals increases. These results are, however, premised on a so-called "impartial culture" assumption: any logically possible preference ordering is assumed to be as likely to be held by an individual as (...)

    This paper approaches the choice between the open and closed nuclear fuel cycles as a matter of intergenerational justice, by revealing the value conflicts in the production of nuclear energy. The closed fuel cycle improve sustainability in terms of the supply certainty of uranium and involves less long-term radiological risks and proliferation concerns. However, it compromises short-term public health and safety and security, due to the separation of plutonium. The trade-offs in nuclear energy are reducible to a chief trade-off (...)

    Mechanistic philosophy of science views a large part of scientific activity as engaged in modelling mechanisms. While science textbooks tend to offer qualitative models of mechanisms, there is increasing demand for models from which one can draw quantitative predictions and explanations. Casini et al. (Theoria 26(1):5–33, 2011) put forward the Recursive Bayesian Networks (RBN) formalism as well suited to this end. The RBN formalism is an extension of the standard Bayesian net formalism, an extension that allows for modelling the hierarchical (...)

    Substrate cycles are ubiquitous structures of the cellular metabolism (e.g. Krebs cycle, fatty acids -oxydation cycles, etc... ). Moiety-conserved cycles (e.g. adenine nucleotides and NADH/NAD, etc...) are also important.The role played by such cycles in the metabolism and its regulation is not clearly understood so far. However, it was shown that these cycles can generate multistationarity (bistability), irreversible transitions, enhancement of sensitivity, temporal oscillations and chaotic motions (Hervagault & Canu, 1987; Hervagault & Cimino, 1989; Reich (...)

    Economic stories with a rational choice structure usually entail closure or equilibrium. This paper argues that Knightian uncertainty and Kirznerian alertness allow economists to construct plausible accounts of open-ended processes such as virtuous cycles and vicious circles without abandoning the centrality of instrumental rationality. The basic form of such stories is explored and two example cases are put forward.

    Abstract Rosser's thoughtful and careful review of my book on business cycles reflects a different methodological stance than my own. I believe that economic theory and macroeconomics cannot escape using the concept of risk, even though, as Rosser points out, risk is not a simple unidimensional magnitude in many circumstances. I view the rational expectations assumption as a useful way of presenting a theory, rather than as a descriptive account of real?world expectations.

    Real business cycle theory, as exemplified by Fischer Black's Business Cycles and Equilibrium, posits that business cycles are due to random ?technology shocks,? and not to monetary, fiscal or other government policies. Rational expectations and complete markets are supposed to enable decision makers to avoid the costly mistakes that would otherwise result from policies that distort incentives to borrow and invest. This paper questions the assumptions of rational expectations and complete markets from an Austrian?school perspective. It argues (...)

    The exogenous cycles and population dynamics of the community at Penrith, Cumbria, England, have been studied (1557-1812) using aggregative analysis, family reconstitution and time series analysis. This community was living under marginal conditions for the first 200 years and the evidence presented is of a homeostatic regime where famine, malnutrition and epidemic disease acted to regulate the balance between resources and population size. This provides an ideal historic population for an investigation of the direct and indirect effects of malnutrition. (...)

    In his sociological works Pareto developed a theory of cyclical social change within the general equilibrium framework. Building on an earlier propositional formalization, we translate Pareto's theory into a series of simultaneous equations and simulate the equation system. The dynamic behavior of the simulation is consistent with Pareto's predictions and demonstrates the internal logic of the theory.

    This essay is a reading of Aristotle’s account in Meteorology I.14 of changes in local environmental conditions and its significance for Aristotle’s understanding of nature and change more generally. That account shows how local environments are complex bodies, and so change through habituation: the sedimentation of patterns of activity through repeated activity/change. In turn, this shows how the regularity of what is by nature is a matter of the relative stability of habits in the face of unceasing generation and destruction. (...)
