Scientific advancement of two nature-based interventions for people with dementia, The: adaptive riding and adaptive gardening

2021 Spring.Includes bibliographical references.People living with dementia are at risk for decreased quality of life (QoL). QoL may be supported through adaptive riding and horsemanship activities and adaptive gardening, two nature-based interventions; yet, they require further scientific advancement. This dissertation sought to scientifically advance adaptive riding and adaptive gardening for people with dementia. Study one, a mixed methods descriptive case study, addressed the development of an adaptive riding intervention and resulted in a logic model linking its purpose, assumptions, components, occupational opportunities, and immediate outcomes of QoL for participants with dementia. Study two, a quantitative case study compared adaptive riding and adaptive gardening, targeted development and piloting, and revealed that both supported participants' emotional well-being and participation, two dimensions of QoL, with significantly longer durations of complex participation observed during adaptive riding. Study one provided the first published logic model for a nature-based intervention involving animals, whereas study two served as the first nature comparison for this population. Both interventions were scientifically advanced from development to piloting and described in-depth to inform future replication. Next, care partners' perceptions should be explored. The novel observational approach applied in both studies may be helpful to describe other nature-based interventions, and may also contribute to occupational science with a method for situating occupations in the here and now

Computer Aided Verification

The open access two-volume set LNCS 11561 and 11562 constitutes the refereed proceedings of the 31st International Conference on Computer Aided Verification, CAV 2019, held in New York City, USA, in July 2019. The 52 full papers presented together with 13 tool papers and 2 case studies, were carefully reviewed and selected from 258 submissions. The papers were organized in the following topical sections: Part I: automata and timed systems; security and hyperproperties; synthesis; model checking; cyber-physical systems and machine learning; probabilistic systems, runtime techniques; dynamical, hybrid, and reactive systems; Part II: logics, decision procedures; and solvers; numerical programs; verification; distributed systems and networks; verification and invariants; and concurrency

Social Networking: Closing the Achievement Gap Between Regular and Special Education Students

This applied dissertation was designed to analyze the effects of social networking for educational purposes on the academic achievement of regular and special education students in the secondary school setting. The effect of social networking on student learning has not been determined. There is a limited amount of research on how and to what extent teachers use social networking within the parameters of instruction. There is even less research distinguishing the effects of social networking on the academic achievement on regular and special education students. The student participants engaged in discussion forums as their primary social networking experience. Of the 155 participants, 94 were enrolled in a class that required participation in asynchronous discussion forum, and 61 were enrolled in a class with more traditional instruction devoid of social networking. The treatment consisted of 12 discussion prompts created by the teacher in the Blackboard course management system. The analysis of student test data showed no significant difference in mean scores attributable to social networking when educational status was ignored. When educational status was not ignored, however, the significant difference of mean scores between all regular education and all special education students was found to be highly unlikely to have been due to chance. This study also found that there was an interaction between educational status and social networking. The infusion of educational social networking helped narrow the achievement gap between regular and special education students

Making Representations Matter: Understanding Practitioner Experience in Participatory Sensemaking

Appropriating new technologies in order to foster collaboration and participatory engagement is a focus for many fields, but there is relatively little research on the experience of practitioners who do so. The role of technology-use mediators is to help make such technologies amenable and of value to the people who interact with them and each other. When the nature of the technology is to provide textual and visual representations of ideas and discussions, issues of form and shaping arise, along with questions of professional ethics. This thesis examines such participatory representational practice, specifically how practitioners make participatory visual representations (pictures, diagrams, knowledge maps) coherent, engaging and useful for groups tackling complex societal and organizational challenges. This thesis develops and applies a method to analyze, characterize, and compare instances of participatory representational practice in such a way as to highlight experiential aspects such as aesthetics, narrative, improvisation, sensemaking, and ethics. It extends taxonomies of such practices found in related research, and contributes to a critique of functionalist or techno-rationalist approaches to studying professional practice. It studies how fourteen practitioners using a visual hypermedia tool engaged participants with the hypermedia representations, and the ways they made the representations matter to the participants. It focuses on the sensemaking challenges that the practitioners encountered in their sessions, and on the ways that the form they gave the visual representations (aesthetics) related to the service they were trying to provide to their participants. Qualitative research methods such as grounded theory are employed to analyze video recordings of the participatory representational sessions. Analytical tools were developed to provide a multi-perspective view on each session. Conceptual and normative frameworks for understanding the practitioner experience in participatory representational practice in context, especially in terms of aesthetics, ethics, narrative, sensemaking, and improvisation, are proposed. The thesis places these concerns in context of other kinds of facilitative and mediation practices as well as research on reflective practice, aesthetic experience, critical HCI, and participatory design
