(Elisabeth Marigo) Interconnection agreements in the telecommunications industry have always been constrained by regulation. Internet interconnection has not received the same level of scrutiny. Recent debates regarding proposed mergers, network neutrality, Internet peering, and last mile competition have generated much discussion about whether Internet interconnection regulation is warranted. In order to determine whether such regulation is necessary, policymakers need appropriate metrics to help gauge a network provider's market power. Since Internet interconnection agreements are typically not published publicly, policymakers must instead rely on proxy metrics and inferred interconnection relationships. Alessio D'Ignazio and Emanuele Giovannetti have attempted to address this challenge by proposing a standard set of metrics that are based on and assessed using network topology data. They suggest two metrics, referred to as customer cone and betweenness, as proxies for market size and market power. This thesis focuses on the efficacy of the proposed customer cone and betweenness metrics as proxies for network market size and market power.

Entrepreneurship is a powerful engine for moving from idea to impact, but for-profit investments in early-stage companies fail to account for investors' charitable objectives and are not rewarded for social returns. Conversely, tax-shielded "charitable" funds are rarely used in for-profit technology companies regardless of their desirable social outcomes. As a result, there is often a limited amount of capital available to companies in areas such as energy, water and human disease because neither pure philanthropic nor pure profit motives sufficiently justify investment. Traditional explanations for funding gaps fail to recognize that the shortfall due to both the risk profile of potential investments, and the poor match between the social and private interests of "investors" and the types of vehicles that might allow a mix of philanthropic and financial motives to sit side-by-side. To address this challenge, we asked a simple question: What financial approaches and organizational structures can be deployed at the intersection of the non-profit and for-profit boundary to address the funding gaps in science and engineering commercialization? To explore this issue, we conducted interviews, reviewed legal texts and relevant literature, and compiled data from online sources. Our findings reveal a sophisticated set of tools that are historically under-used, but which have the potential to advance many areas of science and engineering that hold solutions to global issues, such as health, environment, water, and energy.

(Ariadne Geneviève) This thesis explores the application of open design to the process of developing physical products. Open design is a type of decentralized innovation that is derived from applying principles of open source software and crowdsourcing to product development. Crowdsourcing has gained popularity in the last decade, ranging from translation services, to marketing concepts, and new product funding. However, it is only in the past few years that open design has been considered as a method to create more innovative products in less time and for less money. While truly open design requires participants to collaborate and make contributions at each stage of the product development process, applications of open design to physical product development have been limited to accepting external contributions at only certain, less technical phases of design, such as planning, idea generation, or obtaining idea feedback. This thesis seeks to explore two questions related to creating a tool for open design in physical product development: what kind of tool can be developed to support crowdsourcing the full development of a physical product, and what types of design environments can benefit from this tool? Through a collaboration with GE Global Research for DARPA's Adaptive Vehicle Make (AVM) program, this thesis presents an early prototype of an online tool that allows for the open design of an entire product development process, in application to the development of a vehicle. Then, a framework is developed in order to identify the tool's applicability to other product development industries. Interviews with potential lead users in a number of different industrial sectors were conducted to better understand how this open design environment might be used and adapted for applications outside of a DARPA-driven vehicle design domain. Though the sensitive nature of projects in the defense and medical device industries prohibits this tool from used for its intended crowdsourcing purposes, there is promise for further development of the tool for uses in academic and education environments, and as an internal project management tool in other product development industries, such as aviation and consumer product design.

There is widespread investment of resources in the fields of Science, Technology, Engineering, Mathematics (STEM) education to improve STEM interests and skills. This thesis tackles the dual objectives of building crowdsourcing cluster flight software and educating students using collaborative gaming and competition, both in virtual simulation environments and on real hardware in space. The concept is demonstrated using the SPHERES Zero Robotics Program which is a robotics programming competition. The robots are nanosatellites called SPHERES - an experimental testbed to test navigation, formation flight and control algorithms - onboard the International Space Station (ISS). Zero Robotics allows students to access SPHERES through a web-based interface and the robust programs run on the hardware in microgravity, supervised by astronauts. The apparatus to investigate the influence of collaboration was developed by (1) building new web infrastructure and an Integrated Development Environment where intensive interparticipant collaboration is possible, (2) designing and programming a game to solve a relevant formation flight problem, collaborative in nature - and (3) structuring a tournament such that inter-team collaboration is mandated. The web infrastructure was built using crowdsourcing competitions too, to demonstrate feasibility of building software end-to-end through crowdsourcing. The multi-objective design of experiments had three types of collaborations as variables - within matches (to achieve game objectives), inter-team alliances and unstructured communication on online forums. The data used to evaluate objective achievement were simulation competition scores, website usage statistics, post-competition surveys and satellite telemetry from ISS hardware demonstrations. All types of collaboration showed positive influence on the quality of solutions achieved. Educationally, they showed mixed results and lessons on improving their process of implementation for more impact have been documented. Overall, this thesis ratifies the applicability of the developed framework for crowdsourcing spaceflight software and educating students and maps the utility of collaboration in this framework. A systems dynamics model for generalizing the framework into other programs for simultaneous crowdsourcing and education outreach has been proposed and management policy concerns highlighted.
