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:
The theory of ‘punctuated equilibria’ was formulated by two paleontologists, Niles Eldredge and Stephen Gould, in 1972 and has been the focus of considerable controversy within the evolutionary sciences ever since. The primary intentions of this thesis are to relate the history of punctuated equilibria and to examine how it has affected evolutionary science. Several modes of analysis have been used to illuminate the history: The sociological perspectives of Pierre Bourdieu and Bruno Latour (who see scientific debate as a ‘struggle for authority’); Rhetorical analysis of some of the key documents; Communication with practising scientists via questionnaires and correspondence; Citation Analysis. Chapter 1 gives a short summary of the history and introduces the methods and socio-philosophical perspectives used to illuminate the history. Chapters 3 and 4 examine the rhetorical process by which Eldredge and Gould constructed the ‘punctuationist revolution’. Chapters 2, 3, 5 and 6 relate the history of punctuated equilibria.

Abstract:
Currently, Title II of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT Act) Act of 2001 appears to be stalled as a result of controversy over the intent and meaning of the law. Proponents of the title advocate the necessity of the act to combat modern terrorism, whereas opponents warn of circumventions of the Fourth Amendment of the U.S. Constitution. Using punctuated equilibrium as the theoretical foundation, the purpose of this case study was to explore the dialogue and legal exchanges between the American Civil Liberties Union and the Department of Justice related to the National Security Agency's metadata collection program. In specific, the study sought to explore the nature of resistance to changes needed to mollify the controversies associated with Title II. Data for this study were acquired through publicly available documents and artifacts including transcripts of Congressional hearings, legal documents, and briefing statements from the US Department of Justice and the American Civil Liberties Union. These data were deductively coded according to the elements of PET and then subjected to thematic analysis. Findings indicate that supporters and opponents of the law are locked in a consistent ideological polarization, with supporters of the law touting the necessity of the authorizations in combatting terrorism and opponents arguing the law violates civil liberties. Neither side of the debate displayed a willingness to compromise or acknowledge the legitimacy of the other viewpoint. Legislators who accept the legitimacy of both researched viewpoints could create positive social change by refining the law to meet national security needs while preserving constitutional protections.

Full text
Abstract:
This thesis provides a study of United Kingdom (UK) macroeconomic policy and economic ideas. Specifically, the thesis seeks to explore the reasons when and why UK macroeconomic policy and economic ideas exhibits change or continuity. The central contention of this thesis is that the model of punctuated equilibrium provides a flawed understanding and explanation of when and why policies and idea exhibit continuity and change in UK macroeconomic policymaking. In particular, the thesis seeks to fill two gaps in our existing knowledge of UK economic policymaking, which emerge from critical literature reviews. The first gap pertains to the need for greater specificity in our understanding and definition of orthodox UK macroeconomic policy. The second gap relates to the need for a superior understanding of when and why UK macroeconomic policy and economic ideas exhibits change and continuity. The original contribution of this thesis to the literature on UK economic policymaking arises from the two research findings generated in Chapters Three and Four, which are then tested in a series of case-study chapters in the second half of the thesis. The first research finding is the provision of greater precision in our understanding and definition of orthodox macroeconomic policy. The second research finding is the identification of a historical pattern in UK macroeconomic policymaking, which is named the orthodox cycle. The orthodox cycle utilises the new understanding and definition of orthodox macroeconomic policy to show the continuity of orthodox policy and ideas in UK macroeconomic policymaking, through a series of distinct phases, in the aftermath of crises and changes in government.

Full text
Abstract:
Punctuated equilibrium, a theory of unexpected and sudden change arising out of evolutionary biology and paleontology, has been applied to decision sciences, physics, organizational theory, and group behavior but never to leadership emergence theories. The purpose of the study was to discover how leadership emerges during a period of punctuated equilibrium, a sudden and unexpected change event, using a naturalistic decision making framework. Thus, the research question probed how leadership emergence could be theoretically modeled in a critical event. This grounded theory study was particularly unique because it drew from, and helped unify the four scientific foundations of complexity science, leadership emergence, punctuated equilibrium theory, and naturalistic decision making. Data from 40 retrospective accounts, described in 15 interviews with critical incident intervention specialists, first responders, and wilderness leadership trainers residing in the northeastern region of the U.S. were supplemented by survey and observational data. Initial analyses employed a reflective coding matrix and a concept identification chart. Analysis of synthesized themes identified an event continuum model in which instinct, compassion, and responsibility served as motivating factors for leadership emergence that appeared in close proximity to the change event. Subsequent observable indicators of leadership emergence often included a sense of calm, quick situational assessment, and the tendency of individuals to ignore physical risk. This study found that punctuated equilibrium stimulated leadership emergence in individuals. The most profound implication for social change was that leadership arose in a time of need guided by compassion and a profound sense of responsibility toward one another regardless of formal position in the group.

Abstract:
Year in year out, hundreds of diplomats and civil society representatives partake in a seemingly endless stream of meetings on nuclear disarmament. These meetings seldom produce materially significant agreements. In fact, no nuclear warhead has ever been dismantled as a direct result of multilateral negotiations. And yet the web of institutions that make up the 'multilateral nuclear disarmament framework' continues to expand. Why? In this thesis, I identify three waves of institutional expansion in the multilateral nuclear disarmament framework (1975-1978; 1991-1999; 2013-2017), linking them to crises of legitimacy in the nuclear order. Institutional expansion, I argue, has been driven by 'struggles for recognition' by non-nuclear powers loath to accept permanent legal subordination. Institutional contestation has allowed non-nuclear powers to exercise symbolic resistance to the frozen nuclear hierarchy enshrined by the Nuclear Non-Proliferation Treaty (NPT) and its distinction between nuclear 'haves' and 'have-nots'. But the relegitimising function of institutional contestation reveals an irony: By solving recurrent crises of legitimacy in the nuclear order, the expansion of the disarmament framework has served to stabilise nuclear inequality in the long term. However, the 2017 adoption of the Treaty on the Prohibition of Nuclear Weapons (TPNW) may signal an end to this cyclical pattern of de- and relegitimisation. After half a century of contestation within the hierarchical NPT framework, the TPNW represents a legal negation of nuclear hierarchy as such.

Bush, Andrew Milton. "Time-Averaging and Morphology: Variability in Modern Populations and Fossil Assemblages of Mercenaria (Bivalvia)." Thesis, Virginia Tech, 1999. http://hdl.handle.net/10919/34912.

Full text
Abstract:
The morphologic variability of a fossil assemblage is of interest in many paleontological studies. However, many fossil assemblages are time-averaged; that is, many generations of non-contemporaneous organisms are mixed into the same fossil bed. Assemblages of robust mollusk shells deposited in nearshore marine environments are often time-averaged over 100's to 1000's of years. Mixing many generations of a taxon can increase measured morphologic variability over that of a single generation if morphology is changing during the interval of time-averaging. If morphology is changing, time-averaging can also alter observed correlations between morphologic variables, as well as allometric growth patterns. If morphology is static, then time-averaging will not increase variability or otherwise obscure patterns of morphologic variability. Testing the effects of time-averaging on morphology will help determine the reliability of information derived from the fossil record.

In this study, morphologic variability was compared between 6 standing crop, living populations of Mercenaria campechiensis (Bivalvia) and two fossil assemblages of M. campechiensis and M. permagna. One fossil sample was collected as a series of superposed units that could be analyzed individually or in aggregate. The x,y coordinates of 13 landmarks and pseudolandmarks were recorded on over 600 valves, and variability was calculated using Least Squares Procrustes Analysis. Once corrections were made for allometry, the variabilities of the samples drawn from single time-averaged fossil beds were indistinguishable from the variabilities of the recent samples. For this data set, the variabilities of the fossil samples could be used without reservation to estimate the variability of the standing crop populations from which they formed. Morphology was quite stable over the 100's to 1000's of years that likely passed as the assemblages accumulated.

A small amount of analytical time-averaging of the samples increases variability slightly, but additional analytical time-averaging causes no further increase. Very slight morphologic fluctuations are evident at time spans exceeding 100's to 1000's of years. Lumping geographically separated samples and samples of different species also increases variability.

Morphologic stasis is evident in Mercenaria over 100's to 1000's of years, but previous studies have indicated that evolutionary rates over this time frame are typically high. These studies are based on colonization events, however, and are biased towards high rates. Data gathered here and in previous studies suggest that local populations may evolve rapidly at their founding, but that stasis follows this initial burst of change. This model describes a pattern similar to Punctuated Equilibrium at a lower level of the genealogical hierarchy, and is here termed "Punctuated Equilibrium, Jr." This model can be further tested in empirical studies and should aid in determining the causes of species-level evolutionary patterns.
