New Role Orientations for U.S. EPA Officials in the Next Generation System of Environmental Protection

Ondich, Gregory George 03 May 2001 (has links)
At the start of the twenty-first century, U.S. Environmental Protection Agency (EPA) officials can look back on nearly thirty years of meaningful accomplishments. Toxic releases are down, the air and water are cleaner, and waste disposal methods are greatly improved. Although this is a record of which EPA officials should be proud, is it sufficient to carry them into the next century? Conventional wisdom among scholars, environmental policy advocates, and even EPA officials indicates that it is not. The new century is bringing complex challenges and, in some cases, the changing conditions are threatening the progress EPA has struggled to achieve. Some of the tools and approaches this agency has relied upon historically, such as notice and comment rulemaking, single stakeholder consultations, and positional leadership, are no longer adequate to address existing environmental challenges and new emerging environmental problems. The Common Sense Initiative (CSI) was launched by EPA in mid-1994 as a fundamentally different approach to environmental protection. Its sector-based, multistakeholder, consensus decision-making process was counter to EPA's traditional command-and-control approach. CSI was created with the intent to heal the growing dysfunctional relationships that exist among government co-regulators (i.e., EPA and state and local agencies), the regulated industry, and non-governmental organizations (i.e., environmentalists and environmental justice organizations). Even though EPA officials realized the limitations of the existing regulatory approach, they had trouble "giving up control." Nonetheless, during the four-year history of the CSI process, EPA personnel had an opportunity to see themselves in a different light and to operate in a new organizational regime. Rather than being just regulators, they were able to become solvers of environmental problems. Rather than being position-oriented, they were able to become person-oriented. Instead of seeking ownership and control, they were able to obtain leverage through partnerships and collaboration. In short, EPA officials were building social capital and a new style of management"facilitative leadership. A facilitative leader leads without controlling, communicates without being condescending, and uses synergism to help groups achieve "win-win" results. This new paradigm has the potential to help EPA better adapt in the next generation system of environmental protection. / Ph. D.

Parameter Estimation Using Consensus Building Strategies with Application to Sensor Networks

Dasgupta, Kaushani 12 1900 (has links)
Sensor network plays a significant role in determining the performance of network inference tasks. A wireless sensor network with a large number of sensor nodes can be used as an effective tool for gathering data in various situations. One of the major issues in WSN is developing an efficient protocol which has a significant impact on the convergence of the network. Parameter estimation is one of the most important applications of sensor network. In order to model such large and complex networks for estimation, efficient strategies and algorithms which take less time to converge are being developed. To deal with this challenge, an approach of having multilayer network structure to estimate parameter and reach convergence in less time is estimated by comparing it with known gossip distributed algorithm. Approached Multicast multilayer algorithm on a network structure of Gaussian mixture model with two components to estimate parameters were compared and simulated with gossip algorithm. Both the algorithms were compared based on the number of iterations the algorithms took to reach convergence by using Expectation Maximization Algorithm.Finally a series of theoretical and practical results that explicitly showed that Multicast works better than gossip in large and complex networks for estimation in consensus building strategies.

Consensus Building in Sensor Networks and Long Term Planning for the National Airspace System

Akula, Naga Venkata Swathik 05 1900 (has links)
In this thesis, I present my study on the impact of multi-group network structure on the performance of consensus building strategies, and the preliminary mathematical formulation of the problem on improving the performance of the National Airspace system (NAS) through long-term investment. The first part of the thesis is concerned with a structural approach to the consensus building problem in multi-group distributed sensor networks (DSNs) that can be represented by bipartite graph. Direct inference of the convergence behavior of consensus strategies from multi-group DSN structure is one of the contributions of this thesis. The insights gained from the analysis facilitate the design and development of DSNs that meet specific performance criteria. The other part of the thesis is concerned with long-term planning and development of the NAS at a network level, by formulating the planning problem as a resource allocation problem for a flow network. The network-level model viewpoint on NAS planning and development will give insight to the structure of future NAS and will allow evaluation of various paradigms for the planning problem.

Exercise and physical activity in people with multiple sclerosis : an exploration of priorities, meanings and implications for clinical practice

Stennett, Andrea M. January 2016 (has links)
Aims: Exercise and physical activity have been found to be beneficial in managing disabilities caused by multiple sclerosis (MS). Despite the known benefits, people with MS (pwMS) are inactive. Research has focused on structured exercise programmes, rarely considering a broader range of activities, which pwMS integrate into everyday life. The aims of this study were to gain in-depth understanding of the priorities and meanings of exercise and physical activity from the perspective of pwMS and to explore how these might inform clinical practice. Methods: a mixed methods approach using three interconnected studies was adopted: Study 1: A four-round Delphi questionnaire scoped and determined consensus of priorities for exercise and physical activity and the reasons why pwMS (n=101) engaged in these activities. Content and statistical analyses were utilised. Study 2: Sixteen face-to-face, semi-structured interviews were conducted with pwMS to explore the meanings ascribed to exercise and physical activity in relation to the Delphi study. Study 3: Three focus groups involving 14 physiotherapists explored perceptions about exercise and physical activity. Data were analysed for studies 2 and 3 using Framework Analysis and themes developed. Results: outcome from each phase 1. Study 1 revealed that the prioritised exercise and physical activity practices and the reasons why pwMS (n=70) undertook these activities were diverse. Consensus was found for the exercise and physical activity practices (W=0.744, p < 0.0001) and the reasons why pwMS engaged in these activities (W=0.723, p < 0.0001). 2. Study 2 demonstrated that the meanings pwMS ascribed to exercise and physical activity was beyond ‘movement’ reflecting how they lived with a variable and progressive condition. Contextual factors, specifically personal factors were dominant influences. 3. Study 3 highlighted that physiotherapists shared similar views in some aspects to pwMS, however physiotherapists perceptions of exercise and physical activity were predominately influenced by their theoretical knowledge. Conclusion: The priorities and meanings ascribed to exercise and physical activity were ‘a matter of perspective’ and context driven. Understanding the strategies used by pwMS for prioritisation might help clinicians support pwMS more effectively in their decision making about exercise and physical activity. Taking this approach creates the opportunity to deliver a more focused patient-centred approach in the management of MS. Recommendations for clinical practice and further research were identified.

Strategic consensus building : A single case study in a merged organization

Buijs, Sonja, Langguth, Julia January 2017 (has links)
Background: Considering high merger failure in the process of strategy implementation, there is a need to elaborate on strategic consensus building during this major organizational change. Purpose: To gain understanding about the strategic consensus building process in a merged organization from a teleological perspective. The premerger influence and the intervening circumstances are expected to affect the process of consensus building. Methodology: A single case study approach was taken by interviewing twelve senior managers from two hierarchical levels as well as five managers from the corporate strategy department of a merged organization to gain a comprehensive understanding of the research topic. Findings: The empirical findings indicated that consensus on strategic priorities is essential for further development of a merged organization. In addition, this study has identified three strategic consensus building facilitators vertical communication, transparency, and agility.
