Abstract:
We investigate the equilibria of CIO work. We apply the punctuated equilibrium paradigm based socio-technical model as our theoretical basis. We use this model to visually describe the impacts of business interruptions (=punctuations) on IT executives' perceived equilibria of work. We enhance the punctuated model with constructs taken from Granovetter's social network theory to better understand social mechanisms influencing IT executives' perceptions. We examined empirically perceptions about the equilibria of work and the role of IT in business in a media company during the years 2010-16. We collected data with the interview data collection method by conducting several interview rounds. Interview findings revealed that the equilibria of work were seen differently at three organizational levels. Also, the role of IT in business and the responsibilities of IT functions were seen in varied ways. The punctuated socio-technical equilibrium model together with the constructs of Granovetter's social network theory offered insightful theoretical explanations for our findings.

Abstract:
When I was invited to participate in a symposium designed to consider the possible implications of the theory of punctuated equilibria for the study of political science, I faced the need to reexamine some fundamental questions. These transcended such issues as whether and how frequently the phenomenon referred to as punctuated equilibrium occurred, and whether it might indeed be similar to some phenomena studied by political scientists. Rather, I felt it necessary to establish for myself whether, when, and how any biologically based theory or set of hypotheses could be applied to the realm of the social sciences and what cautions might be demanded by such application.

Abstract:
From the first realization that organic life on this planet has evolved over geologic time, scientists have speculated about the time interval required for these changes to occur. For many years Darwin's idea of slow incremental changes, gradualism, was the accepted model. In the 1970s Stephen Gould (1941-2002) and Niles Eldridge (b. 1943) provided an alternative model of very rapid evolutionary change, followed by long periods of stability, which they called punctuated equilibria. It now appears that Henry Shaler Williams, a geology professor at Cornell University, arrived at the same interpretation almost one hundred years earlier, but only stated this belief in his class lecture notes. He, like Gould and Eldridge, noticed that the fossil record provides evidence that organisms evolved by very fast physical changes occurring in only a few generations and in a very short geological time interval. Then the organisms appear to undergo almost no change for long periods of time; i.e., long periods of stability through many generations. Exactly why Williams did not produce a formal publication of his concept remains a mystery, but his lecture notes from the early 1880s clearly demonstrate that he had developed the idea of punctuated equilibria.

Abstract:
We re-examine the evolutionary dynamics of RNA secondary structures under directional selection towards an optimum RNA structure. We find that the punctuated equilibria lead to a very slow approach to the optimum, following on average an inverse power of the evolutionary time. In addition, our study of the trajectories shows that the out-of-equilibrium effects due to the evolutionary process are very weak. In particular, the distribution of genotypes is close to that arising during equilibrium stabilizing selection. As a consequence, the evolutionary dynamics leave almost no measurable out-of-equilibrium trace, only the transition genotypes (close to the border between different periods of stasis) have atypical mutational properties.

Abstract:
The reform of public water utilities has received increasing attention over the past decade. In this paper, the reform paths of five public water utilities from five different developing countries are compared. This paper finds that for each case, an external event or crisis brought the issue of water services high on to the political agenda, leading to a window of opportunity in which relatively radical reforms could be implemented. However, as political support for continued reforms withered, performance improvements became difficult to sustain. Without continued political support, performance improvements can be followed by a relapse to poor performance.

Fractals are formed by avalanches, driving the system toward a critical state. This critical state is a fractal in d spatial plus one temporal dimension. Long range spatial and temporal properties are described by different cuts in this fractal attractor. We unify the origin of fractals, 1/f noise, Hurst exponents, Levy flights, and punctuated equilibria in terms of avalanche dynamics, and elucidate their relationships through analytical and numerical studies of simple models.

Abstract:
AbstractStudies of policy change have advanced to the point where the basic contours and factors driving policy sequences are now reasonably well identified and understood with a great deal of empirical evidence pointing to the prevalence of punctuated equilibrium processes in many policy fields. However the reasons why such processes occur is less well understood. Most attention to date has focused upon homeostatic models in which exogenously-driven shocks undermine institutionally entrenched policy equilibria. This article addresses the difficulties this account faces and the conceptual challenges which must be overcome to provide a solid grounding for the understanding and analysis of long-term policy dynamics. It focuses on the merits and demerits of alternative explanations featuring either random junctures and ‘positive-return’ sequences – path dependency – or embedded junctures and ‘reactive’ sequences – process sequencing. Models of policy-making over time using the latter two concepts, it is argued, are more likely to account for the large majority of policy dynamic than the former.

Abstract. The early, coiled stages of Orbulina suturalis and O.universa are described from both Middle Miocene (zones N9–N12) and Quaternary samples. The coiling mode of Orbulina is unique to that genus, and has remained unchanged (as have the spines characteristic of the coiled growth stage) since that genus and its species first evolved. Orbulina universa is monophyletic and its evolutionary history appears to provide an example of “punctuated equilibria” in the development of Cainozoic Globigerinacean development. “O. suturalis “, on the other hand, appears to be a name which has been applied both to the Middle Miocene species and to phylogenetically different forms of Quaternary age.

Full text
Abstract:
AbstractMost of the work on policy dynamics focuses on the agenda-setting stage of the policy cycle and argues that policy issues wax and wane in public attention, generating either a cyclical or evolutionary pattern of governmental activity in particular policy sectors. Anthony Downs's notion of a periodic “issue-attention cycle” and Frank Baumgartner and Bryan Jones's notion of a stepped or “punctuated equilibrium” pattern of policy change are prominent in the literature, but have received little empirical and virtually no cross-national verification. Utilizing the analysis of time-series data gathered on nuclear energy and acid rain issues appearing on government and public agendas in Canada over the period 1977–1992, this article elaborates the elements of the two models and subjects both to empirical testing. The article finds little support for either model in the Canadian case and argues the assumptions behind the models must be altered to account for this anomalous case.

Full text
Abstract:
Explaining the origin and maintenance of biodiversity is critical for understanding the potential consequences of present-day environmental change on ecological communities, as well as the evolutionary history of ecosystems in the Earth's past. Much effort in theoretical ecology has focused on identifying mechanisms that promote stable coexistence of species at equilibrium. However, in a consumer–resource model of competition along an environmental gradient, high-diversity assemblages have the potential to persist in non-equilibrium states for millions of generations with very little species loss. Species' populations in such competitively accommodated communities show slow drift; if disrupted, they rapidly reorganize into alternative persistent states. Fossil examples of prolonged ecological stability lasting 1–5 Myr punctuated by rapid reorganization (e.g. brachiopods from the Permian Reef of west Texas) suggest that some palaeocommunities represent a record of periodically disrupted transient states rather than stable equilibria. The similarity between the theoretical results reported here and palaeontological data suggests that the maintenance of high-diversity communities, both in the past and present, may reflect long-duration, non-equilibrium transient dynamics. If so, this has implications for the response of such communities to present-day environmental change, as well as for the evolution of lineages in such systems.

This collection of essays, written over the past fifteen years by one of the more intrepid defenders of current Darwinian theory, contains material that will be of interest both to historians and philosophers of science and, since Ruse writes well and in an accessible manner, to an even wider audience. A preliminary glance at the contents primes one to expect to be both engaged and provoked; one is not disappointed. The essays include historical speculation on some of the views of Charles Darwin, a defence of human sociobiology and discussion of its feminist critique, punctuated equilibria theory, teleology in biology, extraterrestrial biology and moral theory, the plate tectonic revolution in geology, and the relationship between evolutionary theory and Christian ethics.
