Achievement of many long-term goals requires sustained practice over long durations. Examples include goals related to areas of high personal and societal benefit, such as physical fitness, which requires a practice of frequent exercise; self-education, which requires a practice of frequent study; or personal productivity, which requires a practice of performing work. Maintaining these practices can be difficult, because even though obvious benefits come with achieving these goals, an individual's willpower may not always be sufficient to sustain the required effort. This dissertation advocates addressing this problem by designing novel interfaces that provide people with new practices that are fun and enjoyable, thereby reducing the need for users to draw upon willpower when pursuing these long-term goals. To draw volitional usage, these practice-oriented interfaces can integrate key characteristics of existing activities, such as music-making and other hobbies, that are already known to draw voluntary participation over long durations. This dissertation makes several key contributions to provide designers with the necessary tools to create practice-oriented interfaces. First, it consolidates and synthesizes key ideas from fields such as activity theory, self-determination theory, HCI design, and serious leisure. It also provides a new conceptual framework consisting of heuristics for designing systems that draw new users, plus heuristics for making systems that will continue drawing usage from existing users over time. These heuristics serve as a collection of useful ideas to consider when analyzing or designing systems, and this dissertation postulates that if designers build these characteristics into their products, the resulting systems will draw more volitional usage. To demonstrate the framework's usefulness as an analytical tool, it is applied as a set of analytical lenses upon three previously-existing experiential media systems. To demonstrate its usefulness as a design tool, the framework is used as a guide in the development of an experiential media system called pdMusic. This system is installed at public events for user studies, and the study results provide qualitative support for many framework heuristics. Lastly, this dissertation makes recommendations to scholars and designers on potential future ways to examine the topic of volitional usage.

Stroke is a leading cause of disability with varying effects across stroke survivors necessitating comprehensive approaches to rehabilitation. Interactive neurorehabilitation (INR) systems represent promising technological solutions that can provide an array of sensing, feedback and analysis tools which hold the potential to maximize clinical therapy as well as extend therapy to the home. Currently, there are a variety of approaches to INR design, which coupled with minimal large-scale clinical data, has led to a lack of cohesion in INR design. INR design presents an inherently complex space as these systems have multiple users including stroke survivors, therapists and designers, each with their own user experience needs. This dissertation proposes that comprehensive INR design, which can address this complex user space, requires and benefits from the application of interdisciplinary research that spans motor learning and interactive learning. A methodology for integrated and iterative design approaches to INR task experience, assessment, hardware, software and interactive training protocol design is proposed within the comprehensive example of design and implementation of a mixed reality rehabilitation system for minimally supervised environments. This system was tested with eight stroke survivors who showed promising results in both functional and movement quality improvement. The results of testing the system with stroke survivors as well as observing user experiences will be presented along with suggested improvements to the proposed design methodology. This integrative design methodology is proposed to have benefit for not only comprehensive INR design but also complex interactive system design in general.

Informal public transport is commonplace in the developing world, but the service exists in the United States as well, and is understudied. Often called "dollar vans", New York's commuter vans serve approximately 120,000 people every day (King and Goldwyn, 2014). While this is a tiny fraction of the New York transit rider population, it is comparable to the total number of commuters who ride transit in smaller cities such as Minneapolis/St Paul and Phoenix. The first part of this study reports on the use of commuter vans in Eastern Queens based on a combination of surveys and a ridership tally, all conducted in summer 2016. It answers four research questions: How many people ride the vans? Who rides the commuter vans? Why do they ride commuter vans? Do commuter vans complement or compete against formal transit? Commuter van ridership in Eastern Queens was approximately 55,000 with a high percentage of female ridership. Time and cost savings were the main factors influencing commuter van ridership. Possession of a MetroCard was shown to negatively affect the frequency of commuter van ridership. The results show evidence of commuter vans playing both a competing and complementary role to MTA bus and subway transit. The second part of this study presents a SWOT analysis results of commuter vans, and the policy implications. It answers 2 research questions: What are the main strengths, weaknesses, opportunities and threats of commuter vans in Eastern Queens? and How do the current policies, rules and regulations affect commuter van operation? The SWOT analysis results show that the commuter van industry is resilient, performs a necessary service, and, with small adjustments that will help reduce operating costs and loss of profits have a chance of thriving in Eastern Queens and the rest of New York City. The study also discusses the mismatch between policy and practice offering recommendations for improvement to ensure that commuter vans continue to serve residents of New York City.

Bicycle sharing systems (BSS) operate on five continents, and they change quickly with technological innovations. The newest “dockless” systems eliminate both docks and stations, and have become popular in China since their launch in 2016. The rapid increase in dockless system use has exposed its drawbacks. Without the order imposed by docks and stations, bike parking has become problematic. In the areas of densest use, the central business districts of large cities, dockless systems have resulted in chaotic piling of bikes and need for frequent rebalancing of bikes to other locations. In low-density zones, on the other hand, it may be difficult for customers to find a bike, and bikes may go unused for long periods. Using big data from the Mobike BSS in Beijing, I analyzed the relationship between building density and the efficiency of dockless BSS. Density is negatively correlated with bicycle idle time, and positively correlated with rebalancing. Understanding the effects of density on BSS efficiency can help BSS operators and municipalities improve the operating efficiency of BSS, increase regional cycling volume, and solve the bicycle rebalancing problem in dockless systems. It can also be useful to cities considering what kind of BSS to adopt.

ABSTRACT

This research reveals how governments cut budgets during fiscal crises and what pattern may emerge based on the cuts. It addresses a significant gap in literature by looking into the details of an agency for a full recession period to explain how cutback requirements were met. Through investigating a large Arizona state agency during the 2008 recession in the United States, the research reveals that cutback management is a stage-by-stage process lagging the immediate deterioration of the state’s economy and that patterns found among cuts are more often rational than not.

Cutbacks in this agency proceeded through three stages: the beginning, middle and the end period of cuts. In each stage, the author used descriptive analysis, process map analysis and cause and effect analysis to explore the features of cuts made. These methods of analysis were used to break down an annual budget reduction into original appropriation budget cuts, mid year reductions and the final budget cuts required to end the fiscal year in balance. In addition, the analytical methods permitted more detailed analysis of specific appropriation line items. The information used was secondary data collected from seven fiscal years around the recession and from various sources, including budgetary materials, legislation, accounting materials and many program reports related to budget cuts.

The findings suggested that across-the-board cuts are implemented at the beginning of cutback stage mainly to non-mandatory programs without jeopardizing the core functions of the agency. Later, in the middle period of the recession, selective cuts are made on large programs. Fund transfers and excess balance transfers are also preferred to reduce the budgets of other restricted funds. At the end stage of budget cuts, new revenue sources are established to support programs which had relied on general fund revenues in the past.

Overall, the cutback process observed in this research reflects decremental and rational patterns of decision making, contrasting with the randomness observed in previous research on cutback management. Across the board cuts are decremental; the remainders are rational, even strategic decisions. This investigation reminds researchers to be aware of the context and the level of observation when analyzing cutbacks.

Advancements in marine and aerospace technology drive legal reform in admiralty and air law. The increased accessibility and affordability of these technologies demand and motivate lawmakers and federal agencies to anticipate potential threats to peoples’ rights and resources in the seas and skies. Given the recent applications of unmanned aircraft in the public and private sectors, developments in aircraft and air law are rapidly becoming more relevant to American Indian and Alaska Native tribes. In anticipation of legal reform, tribal nations are taking steps to assert, expand, and secure their air rights before agencies or the courts attempt to divest their sovereign authority. An analysis of two case studies through a lens of water and federal Indian law locates spaces in American jurisprudence that have the legal foundation and structural capacity to support a greater presence of Indigeneity in airspace. Research findings from these studies answer the following inquiries about tribal airspace sovereignty: where does Indigeneity reside in the US national airspace system and domestic air law, how are tribal air rights strengthened or weakened by American jurisprudence, what strategies do tribes employ to exercise their sovereignty in airspace, and how are tribes planning for future developments in aircraft and air law? Answers lead to proof of how meaningful consultation through collaborative rulemaking produces far greater mutual benefits than burdens for federal agencies and tribes, and much more. Most importantly, these discoveries celebrate a diverse and accumulative strategic legacy of strengthening and expanding tribal sovereignty in the face of imminent threats and possibilities in tribal airspace.

The purpose of this experimental study was to investigate the effects of textual and visual annotations on Spanish listening comprehension and vocabulary acquisition in the context of an online multimedia listening activity. 95 students who were enrolled in different sections of first year Spanish classes at a community college and a large southwestern university were randomly assigned to one of four versions of an online multimedia listening activity that contained textual and visual annotations of several key words. Students then took a comprehension and vocabulary posttest and a survey to measure cognitive load and general attitudes towards the program. Results indicated that textual annotations had a significant positive effect on listening comprehension and that visual annotations had a significant positive effect on how successful students felt. No statistically significant differences were found for other variables. Participants also reported positive attitudes towards vocabulary annotations and expressed a desire to see more annotations during multimedia listening activities of this type. These findings provide further evidence of the impact that multimedia may have on language acquisition. These findings have implications for multimedia design and for future research. Language listening activities should include a variety of vocabulary annotations that may help students to understand what they hear and to help them learn new vocabulary. Further research is needed outside of the laboratory, in the online and increasingly-mobile language learning environment in order to align the research with the environment in which many students currently study. The incorporation of motivation into multimedia learning theory and cognitive load should be explored, as well as new measures of cognitive load.

Wittgenstein’s claim: anytime something is seen, it is necessarily seen as something, forms the philosophical foundation of this research. I synthesize theories and philosophies from Simondon, Maturana, Varela, Wittgenstein, Pye, Sennett, and Reddy in a research process I identify as a paradigm construction project. My personal studio practice of inventing experiential media systems is a key part of this research and illustrates, with practical examples, my philosophical arguments from a range of points of observation. I see media systems as technical objects, and see technical objects as structurally determined systems, in which the structure of the system determines its organization. I identify making, the process of determining structure, as a form of structural coupling and see structural coupling as a means of knowing material. I introduce my theory of conceptual plurifunctionality as an extension to Simondon’s theory. Aspects of materiality are presented as a means of seeing material and immaterial systems, including cultural systems. I seek to answer the questions: How is structure seen as determining the organization of systems, and making seen as a process in which the resulting structures of technical objects and the maker are co-determined? How might an understanding of structure and organization be applied to the invention of contemporary experiential media systems?
