This thesis explores the ecological design of schoolyard environments. It employs a systems approach, and considers energy, hydrologic, biotic, and social systems and their interrelation. The question of how to integrate experiential learning with the school landscape is also examined, as the concept of empowerment through experience in the landscape is a strong component of this project. With insights gained from an extensive literature review, the author tests the design position through the design explorations of a single schoolyard. The design process, described herein, illustrates the potential for ecological schoolyard design. / Master of Landscape Architecture

No / Abstract: This paper focuses on the submerged landscapes of the southern North Sea, an area often referred to as Doggerland, which was inundated as a result of relative sea-level rise at the start of the Holocene. The timing, pattern and process of environmental changes and the implica­ tions for prehistoric (Mesolithic) human communities living in this area have long been a subject of debate and discussion. Recent developments in marine geophysics have pemtitted the mapping of the pre-submergence landscape, leading to the identification oflandforms including river channels and other contexts suitable for the preservation of palaeoecological records. The paper describes multi-proxy (pollen, foraminifera, plant macrofossil and insect) palaeoenvironmental analyses of a vibrocore sequence recovered from a palaeochannel feature c. 80 km off the coast of eastern England. The palaeocbsnnel preserves sediments of Late Pleistocene and Holocene age (MIS2/l); the record suggests that channel incision, probably duting the early Holocene, was followed by a phase of peat formation (c. 9-10 cal ka BP) indicating paludification and the subsequent reactiva­ tion of the cbsnnel (c. 9-6 cal ka BP), initially under freshwater and increasingly brackish/saline conditions, and a final transition to full marine conditions (6-5 cal ka BP). The pollen, macrofossil and beetle records indicate the presence of pre-submergence deciduous woodland, but detailed interpretation of the data is hindered by taphonomic complications.The paper concludes with a dis­ cussion of the problems and potentials of using palaeoenvironmental data to reconstruct complex patterns of environmental change across Doggerland in four dimensions, and considers specific questions concerning the implications of such processes for Mesolithic human communities.

No / The submerged landscape of the North Sea has long been known by archaeologists as an area of Mesolithic occupation, yet despite this the nature of the occupation of this landscape has remained poorly understood due to the submergence of the landscape. This paper presents the results of a “first pass" study to produce an initial model of the carrying capacity of the landscape and its associated demography. This model seeks to explore the impacts of sea level driven landscape change upon the Mesolithic population. The model reveals the diversity of resources present in this landscape and the potential these had to buffer human subsistence from the effects of marine inundation.

No / The UK has recently recognized the importance of tranquil spaces in the National Planning Policy Framework. This policy framework places considerable emphasis on sustainable development with the aim of making planning more streamlined, localized and less restrictive. Specifically it states that planning policies and decisions should aim to "identify and protect areas of tranquillity which have remained relatively undisturbed by noise and are prized for their recreational and amenity value for this reason". This is considered by some (e.g. National Park Authorities) to go beyond merely identifying quiet areas based on relatively low levels of mainly transportation noise, as the concept of tranquillity implies additionally a consideration of visual intrusion of man-made structures and buildings into an Otherwise perceived natural landscape. In the first instance this paper reports on applying a method for predicting the perceived tranquillity of a place and using this approach to classify the level of tranquillity in existing areas. It then seeks to determine the impact of a new build, by taking the example of the construction of wind turbines in the countryside. For this purpose; noise level measurements, photographs and jury assessments of tranquillity at a medium sized land based wind turbine were made. It was then possible to calculate the decrement of noise levels and visual prominence with distance in order to determine the improvement of tranquillity rating with increasing range. The point at which tranquillity was restored in the environment allowed the calculation of the position of the footprint boundary. (C) 2014 Elsevier Ltd. All rights reserved. / yes

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Mary Catherine (Katie) Kingery-Page / Restorative landscapes, healing gardens, and therapeutic gardens can improve mental and physical health. They relieve stress, slow us down and make us appreciate the present moment (Kaplan 1995). Research confirms these benefits: “A restorative environment provides measurable physical and/or psychological benefit to human health” (Krinke 2005, 107). Unfortunately, few restorative landscapes are designed for night time use, though stress and the need for healing occur at all hours of the day and night. To that end, the purpose of this research is to create a set of lighting design strategies that will enable designers to create restorative landscapes for nighttime use and demonstrate how they can be applied. A literature review synthesizing the information on healing garden types, outdoor lighting techniques, and their relationship to Attention Restoration Theory, identified four main components required for a space to be considered restorative. Two precedent studies allowed the author to explore the components of Attention Restoration Theory and healing garden types. The lighting principles that afford these four components and healing garden types that are best suited for an urban public space were layered in a final design to create a restorative urban space that is functional at night. The set of design strategies created with the support of this research was applied to Occidental Square, a public park in Seattle, Washington. The applied design strategies are represented and demonstrated through the site design. With these tools in hand, designers can create spaces for those in need of rejuvenation, restoration, and tranquility not only during the day, but also at night.

Land is a critical element in the formation of, maintenance and continuance of Native identity to tribes in North America. Since time immemorial, Native people have occupied these landscapes in a manner than can perhaps be best described as "persistent." Native views of the land can differ significantly from those of a Western, or Anglo-American tradition. And when managers of these lands come from a Western tradition, dissimilar views on how these lands should be used can become very problematic for Native people. This research examines how five tribes (Pueblo of Acoma, the Hopi Tribe, Pueblo of Laguna, Navajo Nation and Pueblo of Zuni) view their identity and future cultural continuity as their ancestral homelands are inundated by competing uranium mining interests that threaten to destroy the Mount Taylor landscape of northern New Mexico.

Widespread unexplained variations in clinical practices and patient outcomes, together with rapidly growing availability of data, suggest major opportunities for improving the quality of medical care. One way that healthcare practitioners try to do that is by participating in organized healthcare quality improvement collaboratives (QICs). In QICs, teams of practitioners from different hospitals exchange information on clinical practices, with the aim of improving health outcomes at their own institutions. However, what works in one hospital may not work in others with different local contexts, due to non-linear interactions among various demographics, treatments, and practices. I.e., the clinical landscape is a complex socio-technical system that is difficult to search. In this dissertation we develop methods for analysis and modeling of complex systems, and apply them to the problem of healthcare improvement. Searching clinical landscapes is a multi-objective dynamic problem, as hospitals simultaneously optimize for multiple patient outcomes. We first discuss a general method we developed for finding which changes in features may be associated with various changes in outcomes at different points in time with different delays in affect. This method correctly inferred interactions on synthetic data, however the complexity and incompleteness of the real hospital dataset available to us limited the usefulness of this approach. We then discuss an agent-based model (ABM) of QICs to show that teams comprising individuals from similar institutions outperform those from more diverse institutions, under nearly all conditions, and that this advantage increases with the complexity of the landscape and the level of noise in assessing performance. We present data from a network of real hospitals that provides encouraging evidence of a high degree of similarity in clinical practices among hospitals working together in QIC teams. Based on model outcomes, we propose a secure virtual collaboration system that would allow hospitals to efficiently identify potentially better practices in use at other institutions similar to theirs, without any institutions having to sacrifice the privacy of their own data. To model the search for quality improvement in clinical fitness landscapes, we need benchmark landscapes with tunable feature interactions. NK landscapes have been the classic benchmarks for modeling landscapes with epistatic interactions, but the ruggedness is only tunable in discrete jumps. Walsh polynomials are more finely tunable than NK landscapes, but are only defined on binary alphabets and, in general, have unknown global maximum and minimum. We define a different subset of interaction models that we dub as NM landscapes. NM landscapes are shown to have smoothly tunable ruggedness and difficulty and known location and value of global maxima. With additional constraints, we can also determine the location and value of the global minima. The proposed NM landscapes can be used with alphabets of any arity, from binary to real-valued, without changing the complexity of the landscape. NM landscapes are thus useful models for simulating clinical landscapes with binary or real decision variables and varying number of interactions. NM landscapes permit proper normalization of fitnesses so that search results can be fairly averaged over different random landscapes with the same parameters, and fairly compared between landscapes with different parameters. In future work we plan to use NM landscapes as benchmarks for testing various algorithms that can discover epistatic interactions in real world datasets.

Master of Landscape Architecture / Department of Landscape Architecture / Laurence A. Clement, Jr. / Restorative landscapes are a growing trend within health care environments and can have a lasting impact on people if applied within other settings, particularly higher education campuses. Their design captures the many healing qualities of nature that humans are instinctively attracted to (Heerwagen, 2011). Within restorative landscapes, people have been historically found to experience relief of stress, improved morale, and improved overall well-being (Barnes et al., 1999). While campus planning standards do consider the outdoor environment as an extension of the classroom, higher education campuses can do more to utilize the cognitive benefits of nature for students, faculty and staff. This project explores principles and theories of restorative landscape design, empirical psychological research, and campus design to develop a framework that facilitates the creation of restorative campus spaces on higher education campuses. In partnership with the Office of Design and Construction Management at the University of Kansas, the framework was subsequently applied through the design of the landscape for the Center for Design Research on the KU campus. In the context of current campus planning challenges, restorative landscape design is a potentially valuable strategy in strengthening the beneficial roles and efficacy of the campus landscape. This design project explores its application to envision places within a higher education campus that, along with other benefits, relieve stress for students, faculty and staff.

Philosophiae Doctor - PhD / This study investigated the semiotic resources used by Vagina Varsity, a campaign by sanitary towel brand Libresse on the social media platform YouTube to construct meanings around the female body. Vagina Varsity is a South African online advertising campaign on YouTube which marketed their sanitary products, whilst educating, as well as breaking the social stigma, around the black female body. In this study, YouTube was utilized as a space in which to analyze online identities and communication. The study was located within the field of linguistic landscape (LL) studies, including the sub-field virtual linguistic landscapes (VLL), later reformulated as virtual semioscapes. The conceptual framework was undergirded by multimodality/multisemioticity and feminist theory. The study used a mixed methods approach to data collection, and used a virtual linguistic ethnography (VLE) framework to collect the data sources, which included YouTube videos, YouTube comments, and emails. A focus group interview was also conducted, where the Vagina Varsity videos were shown to a group of diverse youth at the University of the Western Cape, South Africa. The embodied discourses which emerged, as well as the discourse strategies of the commentators, were multimodally analysed. The study found that the Vagina Varsity course makes use of multiple modes, including embodied semiotics such as gestures and stylizations of voice, visual modes such as cartoon figures, as well as the strategic use of sound. In addition, the study found that educational content and marketing strategies are both embedded in this campaign, with the educational content overshadowing the advertising aspect. It is for this reason that the YouTube comments and focus group interview were centered on the program itself and not the advertisement. Furthermore, when looking at the medium this campaign used, one sees that the virtual space allows for the teaching of taboo topics, which would not be allowed in traditional educational domains. The virtual space is not only bridging the knowledge gap in the topic of sex education, it also bridges the gap between different communities, as the YouTube comment section allows for people to interact across regional, national and even cultural boundaries. This study also found that Vagina Varsity not only recontextualized the educational genre, but they have also recontextualized the production and consumption of a topic which would otherwise be considered taboo. In terms of the implications for the study, one finds that the stigma that is attached to this subject is removed from this content. Although one cannot say for certain that this type of education will take over the African traditional initiation ceremonies for girls, for example, it can be used to complement some of the content that traditional counselors and social workers use to teach young African women. The fact that the program is formalized in a curriculum that can be found online opens up possibilities for open dialogue across cultures and nations in terms of feminine hygiene. This study contributes to the field of Linguistic Landscapes studies, with specific focus on virtual linguistic landscapes. The study also illustrates that the affordances of the online space allows for a hybrid edutainment space where people can learn about topics which are considered taboo in the domain of formal education. This study also extends the concept of multimodality, by including notions such as semiotic remediation and resemiotization, as well as immediacy and hypermediacy, as tools of multimodal analysis. This study also contributes to studies on gender and sexuality. / 2022-08-31
