Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Jessica Canfield / Landscape architecture is embarking on a new design frontier, one where its practitioners are increasingly being asked by clients to design using credible evidence and to ensure design performance. As design disciplines follow in the footsteps of other evidence-based practices, like medicine and engineering, landscape architecture is poised to become a more scholarly profession – a profession of evidence-based landscape architecture. Evidence-based landscape architecture was first coined and defined in 2011 by Brown and Corry as “the deliberate and explicit use of scholarly evidence in making decisions about the use and shaping of land” (Brown and Corry 2011, 328). Current literature explains the benefits of practicing evidence-based design (EBD). These include ensuring design performance, justifying client investment, quantifying the value of design, systematically managing complex projects, marketing the firm to clients, attracting the most innovative designers to the firm, and adding to the knowledge base of the landscape architecture field. However, little is known about how landscape architecture firms are engaging evidence-based design in daily practice. This thesis examines how four leading landscape architecture firms (Design Workshop, Mithun, Sasaki Associates, and OLIN) have developed unique EBD approaches to integrate, apply, and propagate evidence-based design in professional practice. In order to study and analyze the four firms’ EBD approaches, individual comprehensive case studies were conducted. Qualitative data was collected through: focused interviews with directors and leaders of evidence-based design at each firm; casual observations made during office visits; and, a review of firm literature. A case study framework for EBD approaches in professional practice was developed based on discussion topics that consistently emerged from the interviews. The framework was used to organize, analyze, and present the findings into four major themes. A cross-case analysis was conducted to compare the development, implementation, and effects of EBD approaches at each firm. Findings reveal that each firm has developed an EBD approach to meet the need for engaging complex problems and meeting increasing client expectations for performance. While each firm’s EBD approach is unique, similarities and characteristics emerged between the case studies. The most consistent factors identified across cases include: having academic founders of the firm; the implementation of EBD- or research-specific roles and responsibilities; the creation of tools to organize and understand data; cultivating design cultures to support the EBD approach vision; the communication and transparency of relationships with clients and consultants; and, the reporting of findings for the advancement of the profession. Although any landscape architecture firm is likely to employ at least one of these concepts, the developed integration, application, and propagation of a majority of these concepts is what makes these firms unique and successful in applying EBD in professional practice. It was also found that the design processes themselves vary dramatically across the firms. EBD in practice is therefore not prescriptive and does not always look the same. The findings and case study framework developed in the study are useful primarily for landscape architecture firms looking to develop, integrate, apply, and propagate their own EBD approach.

This dissertation is "A Collective Case Study of Veterans Inside an Arts and Crafts Room and Their Perceptions Regarding Empowerment." This research examined to what degree art making, and in what ways a community of learning contributed to veterans' self-worth and empowerment through their creative activities and interactions inside an arts and crafts room at the VA hospital in Dallas, Texas. Furthermore, an essential reason for this study is to examine veterans in the arts and crafts environment to explore whether their experiences were important, meaningful, and empowering, and especially important in this regard are the interactions among veterans. Empowerment in this context is defined as gaining self-esteem and motivation within oneself. This includes becoming more confident and positive, as well as gaining the ability to learn about one's own identity. It also described how the interactions between the participants are shaped by the social contexts within which they come together. Using post-modern feminist theory, narrative inquiry and care theory, this dissertation describes the ways that the processes and products of creative activity bring empowerment through dialogue and personal stories while using the component of caring during teaching and learning.

The aim of the thesis is to examine how everyday social interactions and relations in a school class in years 8-9 are experienced by pupils and teachers and how they can be understood and improved. The research design is an action research approach and is carried out as a case study involving four teachers and 24 pupils. Four issues are formulated and the teachers and the researcher together suggest how certain problems might be solved, which in turn directs the action process over the period of three school terms. Analytical concepts are used to map and understand pupils’ everyday social relations in terms of peer groups, positions and norms. Eriksson’s (2001) sociological theory on bullying is used to analyze and explain the complexity of a case of bullying. Defined dominating norms that appear to guide the pupils’ social interactions are: (1) You should make room for yourself, be visible and heard, (2) you should have many friends and (3) you should look down on those who study. The everyday social relations are affected by the pupils’ positioning and by the groupings that are formed in the class. Crystalized groups that emerge in the study are: (1) those who make a lot of noise and take up a lot of room, (2) those who study, (3) pupils who are frequently absent, (4) those who feel uncomfortable and (5) those who are outside (a marginalized group). In addition to these findings, three dominating norms among the teachers emerge. These norms guide and affect how the teachers act and think when victimized pupils and their situations are discussed. Teachers’ dominating norms seem to prevail in situations where some pupils are victimized by other pupils in the class. This in turn could contribute to various kinds of moral disengagement on the part of the teachers when dealing with victimizing acts among pupils. From the perspective of the victimized pupils, such a way of acting could be understood as teachers, in their role as “security guarantors”, are unable to prevent the powerlessness of victimized pupils.

Email stress: what are its causes? how is it measured? can it be solved? The literature review revealed that, despite the term being well used and recognised, discussions surrounding the root cause of email stress had reached little consensus and the concept was not well understood. By its very nature, email stress theory had fallen victim to the academic debate between psychological vs. physiological interpretations of stress which, as a result of either choice, limited more progressive research. Likewise an array of email management strategies had been identified however, whilst some generated quick successes, they appeared to suffer longevity issues and were not maintained a few months after implementation in the workplace. The purpose of this research was to determine whether email communication causes employees psychological and physiological stress and investigate the impact of email management strategies in the workplace. A pragmatic philosophy placed the research problem as central and valued the differences between paradigms to promote a mixed-method approach to research. The decision to pair both case studies and action research methods ensured a framework for presenting results and an actionable solution was achieved. In direct response to the research aims an original email stress measuring methodology was devised that combined various data collection tools to measure and investigate email stress. This research design was applied and evaluated 'email free time' and email filing. Results of the study showed an increased stress response to occur during email use, i.e. caused employees' increased blood pressure, heart rate, cortisol and perceived stress, and a number of adverse effects such as managing staff via email, social detachment, blame and cover-your-back culture were identified. Findings revealed 'email free time' was not a desirable strategy to manage email stress and related stressors, whereas email filing was found more beneficial to workers well-being. Consolidation of the data gathered from the literature review and research findings were used to develop an initial conceptualisation of email stress in the form of two models, i.e. explanatory and action. A focus group was conducted to validate the proposed models and a further investigation at the ? was carried out to critique the use of an email training intervention. The results showed some improvements to employees' behaviour after the training, e.g. improved writing style, email checked on fewer occasions each day and fewer sufferers of email addiction. The initial models devised, alongside the latter findings, were synthesised to create a single integrative multidimensional model of email stress and management strategies. The model made an original contribution to knowledge in terms of theory, i.e. to conceptualise email stress, and practice, i.e. to offer practical solutions to the email worker.

Sibling violence is a common occurrence for many children yet this form of family violence has received minimal attention in research compared to other forms of child maltreatment. With parents as an integral component in the lives of many children, parental perceptions and experiences of violence between siblings are important to understand. Furthermore, with the increased variation in family structures within society, inclusion of multiple types of families in research is necessary to encompass a broad understanding of sibling violence. This case study included seven parents from four different family structures to examine their perceptions and experiences of physical and emotional violence between siblings. Three phases of data collection including both quantitative and qualitative data gathered information about participants’ experiences with siblings in childhood, witnessed behaviors between children, behaviors associated with sibling violence and sibling rivalry, and labels used to refer to violence between siblings. Participants were also presented with several case scenarios depicting various sibling interactions in which they processed the degree to which they found the behaviors violent or non-violent. Findings indicate that family structure is less important than past and present environmental and contextual factors in understanding participant differentiation between problematic and non-problematic behaviors between siblings. Data from all three phases helped in the construction of a parental decision-making model of sibling interaction that included consideration of past experiences, children factors, the context of interaction, and family rules when classifying behaviors. Implications of the findings for social work direct practice, policy aimed at addressing violence between siblings, advocacy through parental education, social work education, and future directions for research in the area of sibling violence are presented.

Cluster randomized trials (CRT) are comparative studies designed to evaluate interventions where the unit of analysis and randomization is the cluster but the unit of observation is individuals within clusters. Typically such designs involve a limited number of clusters and thus the variation between clusters is left uncontrolled. Experimental designs and analysis strategies that minimize this variance are required. In this work we focus on the CRT with pre-post intervention measures. By incorporating the baseline measure into the analysis, we can effectively reduce the variance of the treatment effect. Well known methods such as adjustment for baseline as a covariate and analysis of differences of pre and post measures are two ways to accomplish this. An alternate way of incorporating baseline measures in the data analysis is to order the clusters on baseline means and pairmatch the two clusters with the smallest means, pair-match the next two, and so on. Our results show that matching on baseline helps to control the between cluster variation when there is a high correlation between the pre-post measures. Six cases of designs and analysis are evaluated by comparing the variance of the treatment effect and the power of related hypothesis tests. We observed that - given our assumptions - the adjusted analysis for baseline as a covariate without pair-matching is the best choice in terms of variance. Future work may reveal that other matching schemes that reflect the natural clustering of experimental units could reduce the variance and increase the power over the standard methods.

In the literature of information technology acceptance, much empirical evidence exists that is inconsistent with Technology Acceptance (TA) Models. The purpose of this study is to find out why the extant TA models fail to predict in reality as they purport to in theory. This research argues that the extant literature has not been able to explain how individuals actually form their perceptions about using an information technology. Since past research attempting to do this has been unsuccessful or empirically refuted, this research uses an interpretive case study to investigate the experiences of professionals’ adoption and use of an information technology. In particular, this study focuses on the adoption of an Electronic Medical Records System in a healthcare setting. The results of this interpretive investigation show that the interpretive understanding by the traditional TA models researchers is based on the faulty presumption that the people in the organizations are “monolithic users” or “rational decision makers”. This research provides a new interpretive understanding on the adoption and use of an information technology. The adoption and use of an information technology is an emergent phenomenon resulting from the interaction between the technology and the social actors’ different roles. Based on the interpretive understanding, a new positivist understanding is suggested.

This research argues that the information security governance objectives should be grounded in the values of organizational members. Research literature in decision sciences suggest that individual values play an important role in developing decision objectives. Information security governance objectives, based on values of the stakeholders, are essential for a comprehensive security control program. The study uses Value Theory as a theoretical basis and value focused thinking as a methodology to develop 23 objectives for information security governance. A case study was conducted to reexamine and interpret the significance of the proposed objectives in an organizational context. The results suggest three emergent dimensions of information security governance for effective control structure in organizations: resource allocation, user involvement and process integrity. The synthesis of data suggests eight principles of information security governance which guides organizations in achieving a comprehensive security environment. We also present a means-end model of ISG which proposes the interrelationships of the developed objectives. Contributions are noted and future research directions suggested.

The report, A Crucible Moment, published in 2012 by the National Task Force on Civic Learning and Democratic Engagement described a crisis in higher education surrounding the lack of civic learning and engagement opportunities for students. This crisis has led to decreased political participation and a general lack of knowledge in civics education (National Task Force on Civic Learning and Democratic Engagement, 2012). Educating students for citizenship in America’s colleges and universities will assist with sustaining the country’s democracy by engendering a sense of civic responsibility in young adults that will last throughout their lifetime. This qualitative case study examined the relationship between two institutions of higher education (IHEs) and AmeriCorps programs to determine how the partnerships operated and whether they addressed the recommendations for higher education cited in A Crucible Moment. IHEs are using A Crucible Moment as a guiding document to think about civic learning and democratic engagement. While many are in the process of creating new initiatives and programs to address those issues, this study focuses on two existing programs that may provide a framework for strategically integrating civic engagement into higher education using a readily available government resource—AmeriCorps. With recent budget cuts impacting education, it is difficult for many IHEs to obtain additional funding to support initiatives directly related to student learning. As a result, finding resources to implement civic learning and democratic engagement opportunities that are often perceived as tangential to the education process is nearly impossible. AmeriCorps, now in its 20th year of implementation, has had a steady stream of funding and bipartisan support from the government over the years. IHEs that sponsor an AmeriCorps program have the potential to civically engage students and promote mutually beneficial community partnerships. Using inteorganizational collaboration theory as a framework, I examined two different models of IHE-AmeriCorps partnerships. Based on the levels of collaboration, I was able to assess the degree to which these types of partnerships could be feasible at distinctly different IHEs given their organizational structure and resources. Although the findings of this research are not generalizable, they provide insights into how IHE-AmeriCorps partnerships operate and demonstrate that, in the cases examined, they do implement the key recommendations of A Crucible Moment. As a result, an IHE-AmeriCorps partnership could be an effective and relatively inexpensive way for an IHE to enhance their civic engagement opportunities.

This case study examined the leadership practices of one middle school principal in a low-performing rural school in Virginia. The experienced principal participant was in his first year of leadership at the school; he had led other low-performing schools to improved achievement that resulted in earning state accreditation as well as meeting federal Adequate Yearly Progress (AYP) student proficiency targets. The focus school had failed to meet AYP for five consecutive years. The qualitative research design for this study included in-depth, semi-structured interviews with teachers, the principal, the assistant principal, and the principal’s supervisor; a total of 18 interviews were conducted. Throughout the course of the interviews, the principal’s leadership was conceptualized using the framework of the six core components and six key process that form the basis for the Vanderbilt Assessment of Leadership in Education ((VAL-ED) Murphy et al., 2007). The findings that emerged concerning rural school challenges and organizational change affirmed well-supported assertions in the literature. Participants provided a well-conceptualized and expansively defined profile of the principal’s strengths and areas for growth through the lens of the Murphy et al. (2007) framework for learning-centered leadership.
