Description
The current practice of municipal stormwater management in the United States has failed to effectively reduce the amount of pollutants discharged into surface waters. Water impairment as a result of polluted stormwater runoff from urbanized areas remains a significant concern despite federally mandated efforts to reduce the impact of these discharges. To begin addressing these shortfalls the Environmental Protection Agency contracted the National Research Council to investigate the extent of the stormwater program and to identify areas that require improvement in order to more effectively implement the program. Their findings indicated widespread, foundational flaws with the stormwater regulatory structure and proposed new permitting guidelines. The purpose of this study was to explore the specific shortcomings of stormwater management in the Maricopa County region and to suggest the establishment of a regional authority. Doing so would require an alternative permitting regime to replace the current approach of population based municipal permitting with a permit that considered the entire urbanized region. The organizational structure, legality concerns and intergovernmental partnerships needed to properly establish such a regional authority were part of this study. The effect of this approach suggested a more effective, efficient and economical model of municipal stormwater management that better addressed certain Integrated Urban Stormwater Management strategies and began to address the program weaknesses identified by the National Research Council.

Description
With the ongoing drought surpassing a decade in Arizona, scholars, water managers and decision-makers have heightened attention to the availability of water resources, especially in rapidly growing regions where demand may outgrow supplies or outpace the capacity of the community water systems. Community water system managing entities and the biophysical and social characteristics of a place mediate communities' vulnerability to hazards such as drought and long-term climate change. The arid southwestern Phoenix metropolitan area is illustrative of the challenges that developed urban areas in arid climates face globally as population growth and climate change stress already fragile human-environmental systems. This thesis reveals the factors abating and exacerbating differential community water system vulnerability to water scarcity in communities simultaneously facing drought and rapid peri-urban growth. Employing a grounded, qualitative comparative case study approach, this thesis explores the interaction of social, biophysical and institutional factors as they effect the exposure, sensitivity and adaptive capacity of community water systems in Cave Creek and Buckeye, Arizona. Buckeye, once a small agricultural town in the West Valley, is wholly dependent on groundwater and currently planning for massive development to accommodate 218,591 new residents by 2020. Amid desert hills and near Tonto National Forest in the North Valley, Cave Creek is an upscale residential community suffering frequent water outages due to aging infrastructure and lack of system redundancy. Analyzing interviews, media accounts and policy documents, a narrative was composed explaining how place based factors, nested within a regional institutional water management framework, impact short and long-term vulnerability. This research adds to the library of vulnerability assessments completed using Polsky et al.'s Vulnerability Scoping Diagram and serves a pragmatic need assisting in the development of decision making tools that better represent the drivers of placed based vulnerability in arid metropolitan regions.

Description
As global competition continues to grow more disruptive, organizational change is an ever-present reality that affects companies in all industries at both the operational and strategic level. Organizational change capabilities have become a necessary aspect of existence for organizations in all industries worldwide. Research suggests that more than half of all organizational change efforts fail to achieve their original intended results, with some studies quoting failure rates as high as 70 percent. Exasperating this problem is the fact that no single change methodology has been universally accepted. This thesis examines two aspect of organizational change: the implementation of tactical and strategic initiatives, primarily focusing on successful tactical implementation techniques. This research proposed that tactical issues typically dominate the focus of change agents and recipients alike, often to the detriment of strategic level initiatives that are vital to the overall value and success of the organizational change effort. The Delphi method was employed to develop a tool to facilitate the initial implementation of organizational change such that tactical barriers were minimized and available resources for strategic initiatives were maximized. Feedback from two expert groups of change agents and change facilitators was solicited to develop the tool and evaluate its impact. Preliminary pilot testing of the tool confirmed the proposal and successfully served to minimize tactical barriers to organizational change.

Description
Rapidly increasing demand for technology support services, and often shrinking budgetary and staff resources, create enormous challenges for information technology (IT) departments in public sector higher education. To address these difficult circumstances, the researcher developed a network of IT professionals from schools in a local community college system and from a research university in the southwest into an interorganizational community of practice (CoP). This collaboration allowed members from participating institutions to share knowledge and ideas relating to shared technical problems. This study examines the extent to which the community developed, the factors that contributed to its development and the value of such an endeavor. The researcher used a mixed methods approach to gather data and insights relative to these research questions. Data were collected through online surveys, meeting notes and transcripts, post-meeting questionnaires, semi-structured interviews with key informants, and web analytics. The results from this research indicate that the group did coalesce into a CoP. The researcher identified two crucial roles that aided this development: community coordinator and technology steward. Furthermore, the IT professionals who participated and the leaders from their organizations reported that developing the community was a worthwhile venture. They also reported that while the technical collaboration component was very valuable, the non-technical topics and interactions were also very beneficial. Indicators also suggest that the community made progress toward self-sustainability and is likely to continue. There is also discussion of a third leadership role that appears important for developing CoPs that span organizational boundaries, that of the community catalyst. Implications from this study suggest that other higher education IT organizations faced with similar circumstances may be able to follow the model presented here and also achieve positive results.

Description
This dissertation integrates research on boards of directors with human and social capital perspectives to examine board appointments. A director's appointment to a board is in part due to the belief that the individual can contribute critical resources and monitoring to the organization. The ability of a director to provide these resources and monitoring depends on his or her level of human and social capital. This dissertation more fully integrates human and social capital perspectives into our understanding of board appointment events. From these theoretical underpinnings, a model is developed proposing that several human and social capital indicators, including educational level, expertise, director experience, and access to network structural holes, affect the likelihood of joining a new board, joining a prestigious board, and exiting a current board. I also consider a number of contextual- and individual-level variables that may potentially moderate the relationship between a director's human and social capital and director mobility. Through this dissertation, I make a number of contributions to the literatures on boards, board appointments, and human and social capital. First, I offer a more comprehensive perspective of the board appointment process by developing an individual-level perspective of board appointments. Second, I contribute to a more comprehensive understanding of the market for corporate directors. Third, I focus on several salient dimensions of director mobility. Fourth, I contribute to the growing literature on human and social capital at the board and director levels. Finally, I add to the growing literature on director selection.

Description
Nowadays ports play a critic role in the supply chains of contemporary companies and global commerce. Since the ports' operational effectiveness is critical on the development of competitive supply chains, their contribution to regional economies is essential. With the globalization of markets, the traffic of containers flowing through the different ports has increased significantly in the last decades. In order to attract additional container traffic and improve their comparative advantages over the competition, ports serving same hinterlands explore ways to improve their operations to become more attractive to shippers. This research explores the hypothesis that lowering the variability of the service time observed in the handling of containers, a port reduces the total logistics costs of their customers, increase its competiveness and that of their customers. This thesis proposes a methodology that allows the quantification of the variability existing in the services of a port derived from factors like inefficient internal operations, vessel congestion or external disruptions scenarios. It focuses on assessing the impact of this variability on the user's logistic costs. The methodology also allows a port to define competitive strategies that take into account its variability and that of competing ports. These competitive strategies are also translated into specific parameters that can be used to design and adjust internal operations. The methodology includes (1) a definition of a proper economic model to measure the logistic impact of port's variability, (2) a network analysis approach to the defined problem and (3) a systematic procedure to determine competitive service time parameters for a port. After the methodology is developed, a case study is presented where it is applied to the Port of Guaymas. This is done by finding service time parameters for this port that yield lower logistic costs than the observed in other competing ports.

Description
In spite of the existence of successful humble CEOs, the current strategic leadership literature has little understanding regarding what humility is and how humble CEOs influence organizational effectiveness by creating a context to motivate managers. After applying the self-concept framework to integrate the humility literature, I proposed four mechanisms through which CEO humility were related to middle manager ambidextrous behaviors and job performance: CEO empowering leadership, empowering organizational climate, top management team integration and heterogeneity. After developing and validating a humility scale in China, I collected survey data from a sample of 63 organizations with 63 CEOs, 327 top management team members and 645 middle managers to test the research model. Except for top management team heterogeneity, the other three CEO-middle manager mediating mechanisms received moderate support. Specifically, I found that humble CEOs were empowering leaders; their empowering leadership behaviors were positively associated with top management team integration and empowering organizational climate, which in turn correlated positively with middle manager ambidexterity and job performance.

Description
Services outsourcing is a prevalent yet problematic phenomenon. On the one hand, more and more firms are outsourcing services function. On the other hand, we are faced with many services outsourcing failures. This research attempts to uncover some of the omitted causes of services outsourcing failure. It extends a conceptual paper that used social network theory to examine the shifting of the triadic relationship structures among the service buyer, service supplier and the buyer's customers at different stages of the services outsourcing arrangements and its performance implications. This study empirically examines these performance implications. Specifically, this research defines the concept of bridge transfer, which denotes the weakening and dissolution of operational ties between the service buyer firms' and their end customers and the appearing and strengthening of operational ties between the service supplier firms and the end customers. It also empirically derives a measurement scale for this new construct. Further, the effects of bridge transfer on supplier's appropriation behavior, buyer's cost of quality and end customers' quality perception are examined in the context of customer facing services and are contrasted with those entail little or no customer interactions. In addition, the moderating roles of buyer-supplier relationship on the effects of bridge transfer are also examined. An Internet-based survey was administered to firms affiliated with CAPS Research and the Institute of Supply Management as the primary data source (n=137). Principal Component Analyses were used to derive a composite score for each of the model construct. Then linear regressions were used to detect the effects of bridge transfer on services outsourcing outcomes and to detect the moderating role of buyer-supplier relationships on these effects. The results show that bridge transfer is positively correlated to suppliers' appropriate behavior and negatively correlated to end customer's quality perception in the context of customer facing services. The effects of bridge transfer are not found for services that entail little or no interactions with the end customers. Instead, buyer-supplier relationship is found to be a key influencing factor to services outsourcing outcomes in this context. This study helps to pinpoint some of the omitted causes of services outsourcing failures and shed light on how to manage services outsourcing for success.

Description
Economic development over the last century has driven a tripling of the world's population, a twenty-fold increase in fossil fuel consumption, and a tripling of traditional biomass consumption. The associated broad income and wealth inequities are retaining over 2 billion people in poverty. Adding to this, fossil fuel combustion is impacting the environment across spatial and temporal scales and the cost of energy is outpacing all other variable costs for most industries. With 60% of world energy delivered in 2008 consumed by the commercial and industrial sector, the fragmented and disparate energy-related decision making within organizations are largely responsible for the inefficient and impacting use of energy resources. The global transition towards sustainable development will require the collective efforts of national, regional, and local governments, institutions, the private sector, and a well-informed public. The leadership role in this transition could be provided by private and public sector organizations, by way of sustainability-oriented organizations, cultures, and infrastructure. The diversity in literature exemplifies the developing nature of sustainability science, with most sustainability assessment approaches and frameworks lacking transformational characteristics, tending to focus on analytical methods. In general, some shortfalls in sustainability assessment processes include lack of: * thorough stakeholder participation in systems and stakeholder mapping, * participatory envisioning of future sustainable states, * normative aggregation of results to provide an overall measure of sustainability, and * influence within strategic decision-making processes. Specific to energy sustainability assessments, while some authors aggregate results to provide overall sustainability scores, assessments have focused solely on energy supply scenarios, while including the deficits discussed above. This paper presents a framework for supporting organizational transition processes towards sustainable energy systems, using systems and stakeholder mapping, participatory envisioning, and sustainability assessment to prepare the development of transition strategies towards realizing long-term energy sustainability. The energy system at Arizona State University's Tempe campus (ASU) in 2008 was used as a baseline to evaluate the sustainability of the current system. From interviews and participatory workshops, energy system stakeholders provided information to map the current system and measure its performance. Utilizing operationalized principles of energy sustainability, stakeholders envisioned a future sustainable state of the energy system, and then developed strategies to begin transition of the current system to its potential future sustainable state. Key findings include stakeholders recognizing that the current energy system is unsustainable as measured against principles of energy sustainability and an envisioned future sustainable state of the energy system. Also, insufficient governmental stakeholder engagement upstream within the current system could lead to added risk as regulations affect energy supply. Energy demand behavior and consumption patterns are insufficiently understood by current stakeholders, limiting participation and accountability from consumers. In conclusion, although this research study focused on the Tempe campus, ASU could apply this process to other campuses thereby improving overall ASU energy system sustainability. Expanding stakeholder engagement upstream within the energy system and better understanding energy consumption behavior can also improve long-term energy sustainability. Finally, benchmarking ASU's performance against its peer universities could expand the current climate commitment of participants to broader sustainability goals.

Description
The wood-framing trade has not sufficiently been investigated to understand the work task sequencing and coordination among crew members. A new mental framework for a performing crew was developed and tested through four case studies. This framework ensured similar team performance as the one provided by task micro-scheduling in planning software. It also allowed evaluation of the effect of individual coordination within the crew on the crew's productivity. Using design information, a list of micro-activities/tasks and their predecessors was automatically generated for each piece of lumber in the four wood frames. The task precedence was generated by applying elementary geometrical and technological reasoning to each frame. Then, the duration of each task was determined based on observations from videotaped activities. Primavera's (P6) resource leveling rules were used to calculate the sequencing of tasks and the minimum duration of the whole activity for various crew sizes. The results showed quick convergence towards the minimum production time and allowed to use information from Building Information Models (BIM) to automatically establish the optimal crew sizes for frames. Late Start (LS) leveling priority rule gave the shortest duration in every case. However, the logic of LS tasks rule is too complex to be conveyed to the framing crew. Therefore, the new mental framework of a well performing framer was developed and tested to ensure high coordination. This mental framework, based on five simple rules, can be easily taught to the crew and ensures a crew productivity congruent with the one provided by the LS logic. The case studies indicate that once the worst framer in the crew surpasses the limit of 11% deviation from applying the said five rules, every additional percent of deviation reduces the productivity of the whole crew by about 4%.
