This Element presents several frameworks of strategy-making that serve to analyze organizational evolution processes within and beyond the firm. These frameworks form an integrated evolutionary ecological lens to examine the dynamics of strategy-making in organizational evolution. They highlight the role of the internal selection environment for analyzing processes and practices at various managerial levels (top, middle, and operational) within the organization. The Element also explains the role of the CEO in maintaining and updating the internal selection environment and contributing to organizational evolution, as well as making. fundamental decisions about organizational splits of the firm's business models as an ecosystem evolves.
The Residual Lesion Score is a novel tool for assessing the achievement of surgical objectives in congenital heart surgery based on widely available clinical and echocardiographic characteristics. This article describes the methodology used to develop the Residual Lesion Score from the previously developed Technical Performance Score for five common congenital cardiac procedures using the RAND Delphi methodology.
Methods:
A panel of 11 experts from the field of paediatric and congenital cardiology and cardiac surgery, 2 co-chairs, and a consultant were assembled to review and comment on validity and feasibility of measuring the sub-components of intraoperative and discharge Residual Lesion Score for five congenital cardiac procedures. In the first email round, the panel reviewed and commented on the Residual Lesion Score and provided validity and feasibility scores for sub-components of each of the five procedures. In the second in-person round, email comments and scores were reviewed and the Residual Lesion Score revised. The modified Residual Lesion Score was scored independently by each panellist for validity and feasibility and used to develop the “final” Residual Lesion Score.
Results:
The Residual Lesion Score sub-components with a median validity score of ≥7 and median feasibility score of ≥4 that were scored without disagreement and with low absolute deviation from the median were included in the “final” Residual Lesion Score.
Conclusion:
Using the RAND Delphi methodology, we were able to develop Residual Lesion Score modules for five important congenital cardiac procedures for the Pediatric Heart Network’s Residual Lesion Score study.
As the study of our “house,” ecology considers interactions between humans and our environments. Hutchinson noted modern society’s effects, including from overconsumption, on the major cycles of nitrogen, carbon, and other elements, foretelling research on the Earth system. A major driver is agriculture, including the scale of pesticide use, an alarm sounded by Rachel Carson in Silent Spring. Industrial agriculture keeps crop ecosystems in a perpetual early state, Odum contends, trading off calorie production for services provided by more-mature ecosystems, such as water purification. Holling showed that ecosystems can exist stably in different states and be resilient to impacts. Pastoral ecosystems may not have a single equilibrium state, as shown by Ellis and Swift, with implications for development. Species play various roles in ecosystems, and their loss can affect key services, as noted by Ehrlich and Mooney. Conserving biodiversity will benefit from Indigenous knowledge, argue Gadgil and colleagues, including knowledge of the shifting baseline of fisheries, notes Pauly. As Earth urbanizes, rural to urban gradients present a growing research opportunity, McDonnell and Pickett argue.
Socio-environmental research has a rich legacy. Scholarship has evolved to be more interdisciplinary, as long before. Sustainability science builds on von Humboldt, Marsh, and Meadows. Research on social–ecological systems research is informed by Ostrom; resilience by Holling; vulnerability by White, Sen, and Beck; and CHANS by Marsh and Moran. Ecological economics emphasizes the economy as a subset of the Earth, leveraging Ricardo, Jevons, and Daly. Ecosystem services research, informed by Ehrlich and Odum, quantifies benefits from ecosystems. Industrial ecology views industrial systems ecologically, as done by Graedel, Ayres, and Kneese. Political ecology focuses on power relations, as did Marx, Polanyi, Shiva, and Blaikie and Brookfield. Environmental justice, pioneered by Bullard, considers unequal benefits and harms. Other systems research focuses on a given context, as on cities (Childe, Mumford, and McDonnell and Pickett), land (Melville), and food (Liangji, Malthus, Boserup, and Ho). Integrated assessments build on Meadows. Planetary and Anthropocene perspectives focus on the global scale (see Hutchinson, Boff). Legacy readings can help frame socio-environmental relationships and enrich collaborations.
