Although there are many forms of organization on the Web, one of the most prominent ways to organize web content and websites are tags. Tags are keywords or terms that are assigned to a specific piece of content in order to help users understand the common relationships between pieces of content. Tags can either be assigned by an algorithm, the author, or the community. These tags can also be organized into tag clouds, which are visual representations of the structure and organization contained implicitly within these tags. Importantly, little is known on how we use these different tagging structures to understand the content and structure of a given site. This project examines 2 different characteristics of tagging structures: font size and spatial orientation. In order to examine how these different characteristics might interact with individual differences in attentional control, a measure of working memory capacity (WMC) was included. The results showed that spatial relationships affect how well users understand the structure of a website. WMC was not shown to have any significant effect; neither was varying the font size. These results should better inform how tags and tag clouds are used on the Web, and also provide an estimation of what properties to include when designing and implementing a tag cloud on a website.

Description
Fixed-pointer moving-scale tape displays are a compact way to present wide range dynamic data, and are commonly employed in aircraft and spacecraft to display the primary parameters of airspeed, altitude and heading. A limitation of the moving tape format is its inability to natively display off scale target, reference or 'bug' values. The hypothesis tested was that a non-linear fisheye presentation (made possible by modern display technology) would maintain the essential functionality and compactness of existing moving tape displays while increasing situational awareness by ecologically displaying a wider set of reference values. Experimentation showed that the speed and accuracy of reading the center system value was not significantly changed with two types of expanded range displays. The limited situational awareness tests did not show a significant improvement with the new displays, but since no functionality was degraded further testing of expanded range displays may be productive.

Description
Modern day driving continues to burgeon with attention detractors found inside and outside drivers' vehicles (e.g. cell phones, other road users, etc.). This study explores a regularly disregarded attention detractor experienced by drivers: self-regulation. Results suggest self-regulation and WMC has the potential to affect attentional control, producing maladaptive changes in driving performance in maximum speed, acceleration, and time headway.

Description
Cities are increasingly using nature-based approaches to address urban sustainability challenges. These solutions leverage the ecological processes associated with existing or newly constructed Urban Ecological Infrastructure (UEI) to address issues through ecosystem services (e.g. stormwater retention or treatment). The growing use of UEI to address urban sustainability challenges can bring together teams of urban researchers and practitioners to co-produce UEI design, monitoring and maintenance. However, this co-production process received little attention in the literature, and has not been studied in the Phoenix Metro Area.
I examined several components of a co-produced design process and related project outcomes associated with a small-scale UEI project – bioswales installed at the Arizona State University (ASU) Orange Mall and Student Pavilion in Tempe, AZ. Specifically, I explored the social design process and ecohydrological and biogeochemical outcomes associated with development of an ecohydrological monitoring protocol for assessing post-construction landscape performance of this site. The monitoring protocol design process was documented using participant observation of collaborative project meetings, and semi-structured interviews with key researchers and practitioners. Throughout this process, I worked together with researchers and practitioners to co-produced a suite of ecohydrological metrics to monitor the performance of the bioswales (UEI) constructed at Orange Mall, with an emphasis on understanding stormwater dynamics. I then installed and operated monitoring equipment from Summer 2018 to Spring 2019 to generate data that can be used to assess system performance with respect to the co-identified performance metrics.
The co-production experience resulted in observable change in attitudes both at the individual and institutional level with regards to the integration and use of urban ecological research to assess and improve UEI design. My ecological monitoring demonstrated that system performance met design goals with regards to stormwater capture, and water quality data suggest the system’s current design has some capacity for stormwater treatment. These data and results are being used by practitioners at ASU and their related design partners to inform future design and management of UEI across the ASU campus. More broadly, this research will provide insights into improving the monitoring, evaluation, and performance efficacy associated with collaborative stormwater UEI projects, independent of scale, in arid cities.

Description
College and university campuses can play an important role in a student’s life, and campus outdoor spaces have the ability to positively impact various aspects of student health and well-being. It has long been understood that natural environments can promote health and well being, and in recent years research has begun to examine the impact of parks and landscapes in urban settings on subjective well-being (SWB). Subjective well-being (aka “happiness”) refers to
one’s self-reported measure of well-being and is thought of as having a high level of positive affect, low level of negative affect, and high degree of life satisfaction (Diener, 1984).
This study was conducted to assess the interrelationships between affective experiences, SWB, and usage of campus outdoor spaces in order to learn how outdoor spaces on the Arizona State University (ASU) Tempe campus can be enhanced to increase SWB and usage. In total, 832 students completed a survey questionnaire 1,140 times for six campus outdoor spaces. The results showed that students experience the greatest amount of happiness in the Secret Garden
and James Turrell ASU Skyspace, relaxation/restoration is the affective experience most strongly related to SWB, and SWB is negatively correlated with frequency of visits but positively link with duration of visits. To improve student happiness and usage of outdoor spaces on campuses, planners and designers should work on increasing the relaxing/restorative qualities of existing
locations, creating new spaces for relaxation/restoration around campus, reducing the perception of crowding and noise in large spaces, increasing fun/excitement by adding stimuli and/or opportunities for activity and entertainment, and adding equipment necessary for students to perform the activities they want. In addition to the ASU Tempe campus, the methodology and
findings of this research could be used to improve outdoor spaces on other college and university campuses and other types of outdoor environments.

Description
While various collision warning studies in driving have been conducted, only a handful of studies have investigated the effectiveness of warnings with a distracted driver. Across four experiments, the present study aimed to understand the apparent gap in the literature of distracted drivers and warning effectiveness, specifically by studying various warnings presented to drivers while they were operating a smart phone. Experiment One attempted to understand which smart phone tasks, (text vs image) or (self-paced vs other-paced) are the most distracting to a driver. Experiment Two compared the effectiveness of different smartphone based applications (app’s) for mitigating driver distraction. Experiment Three investigated the effects of informative auditory and tactile warnings which were designed to convey directional information to a distracted driver (moving towards or away). Lastly, Experiment Four extended the research into the area of autonomous driving by investigating the effectiveness of different auditory take-over request signals. Novel to both Experiment Three and Four was that the warnings were delivered from the source of the distraction (i.e., by either the sound triggered at the smart phone location or through a vibration given on the wrist of the hand holding the smart phone). This warning placement was an attempt to break the driver’s attentional focus on their smart phone and understand how to best re-orient the driver in order to improve the driver’s situational awareness (SA). The overall goal was to explore these novel methods of improved SA so drivers may more quickly and appropriately respond to a critical event.

Description
As sustainability grows in popularity, it is important to understand what may influence people’s perceptions of the environment so that knowledge of how to motivate people to engage in sustainable practices is obtained. This project investigates people's perceptions on green infrastructure in relation to people’s motivation in order to engage in pro-environmental behavior. This study employs an online survey sent to student athletes at Arizona State University followed up by an semi-constructed interview to understand what kind of access these athletes had to green infrastructure while growing up, how much they value the environment today, and whether or not they attribute their current perceptions of the environment to their childhood access to green infrastructure. Findings suggest that there may be a relationship between student athletes’ access to green infrastructure and a higher value of the environment but only in those who are knowledgeable about how green infrastructure can impact the human population. By showing a possible correlation between access to green infrastructure and motivation to conserve the environment, this study shows the importance of environmental design and how the built environment influences people’s perceptions and behavior toward environmental sustainability.

Description
There are unfortunately very few curricular guides that focus on community engagement within the higher education of landscape architecture. A Beginner’s Guide to Community Engagement in the Curriculum of Landscape Architecture and Urban Planning to Improve Social Justice and Sustainability helps resolve this issue and serves as a resource to students, educators, designers, and more. The guide centralizes a diverse collection of resources, guides students through learning materials, shares insight, and proposes potential community engagement methods. The booklet aims to help readers understand the importance of community engagement in design and shares different curricular approaches to introduce the work to students.

Description
Inequities and exclusions, compounded by the increasing intensity of extreme weather events, pose significant challenges to urban planning for low-elevation coastal zones (LECZ). Inclusive development (ID) and urban flood resilience (UFR) have emerged as widely endorsed solutions by scholars. Granting that they gain substantial support and enthusiasm, they have the potential to transform vulnerable urban areas. While their noble intentions are commendable, the intricacies of ID cannot be overlooked, as UFR often inherits and perpetuates the inequalities ingrained in conventional development paradigms. Given the critical importance of ID and UFR in contemporary urban planning, my dissertation research devolved into their fusion by answering my main research question, what constitutes inclusive urban flood resilience? This investigation was carried out through a series of four secondary research questions distributed over three academic papers, each contributing a unique perspective and insights to this burgeoning field. Through a systematic literature review and employing bibliometric and thematic analyses, Chapter 2 offers a comprehensive understanding of inclusive development and a refined definition of the concept. Subsequently, taking Georgetown, the capital city of Guyana, as a case study, Chapter 3 estimates its UFR and employs dimensionality reduction by way of principal component analysis to present these findings in a transparent manner. Chapter 4 builds on the findings of the previous chapters, by first presenting a novel approach to evaluate inclusive development within the framework of the results of Chapter 2, and secondly, together with a systematic meta-analysis of flood resilience measurements, it offers an examination of the ID-UFR nexus. The findings suggest that the concept of inclusive development is nuanced by context-specific definitions, that flood resilience in Georgetown varies among its sub-districts, and that city dimensions (natural, built, social, economic, and institutional), as assessed by pooling global studies, do not share synergistic relationships, being a measure of inclusive development. These findings are critical to urban planning in Georgetown and similar contexts globally as they provide data-driven guidance for understanding these concepts and applying them toward developing inclusive and flood-resilient cities and communities.

Description
This study explores the processes of designing strategies. The context of this research is scoped to the direct-marketing activities of small farm operators in eastern Iowa. The research intent is to explore and articulate trends in decision-making processes that assist small farm operators in eastern Iowa with direct marketing farm-to-table products, to explore and articulate how the design process creates differentiated value, and to explore and articulate the relationship between the design process and the way that small farm operators in eastern Iowa conceptualize their direct-marketing strategies.
The research design takes a post-positivist approach and uses a grounded theory methodology. The study does not have a starting hypothesis but instead starts with the research intent described previously. Convergent mixed methods and a flexible plan are used for data collection including semi-structured interviews and surveys with key concepts operationalized into Likert scales. The participants are selected from eastern Iowa farmers’ markets and Community Supported Agriculture (CSA) directories. For the qualitative data analysis, a grounded theory method is used to code interview response data, categorize the codes into related groups, and let the themes and sub-themes emerge from the data. For the quantitative data analysis, descriptive and inferential statistics are calculated on the aggregate data set.
The study finds that small farm operators are making strategic decisions about marketing mix variables such as product quality and relationship building, there are statistically significant correlations between design concepts and direct-marketing strategies, and that farmers designed their strategies by using the design process.
