Grounded Figure: A Winery
The nature of figure-ground relationships and their potential for use as a tool for architectural composition was investigated through the design of a winery. Included in the winery were facilities accomodating both the production and consumption of wine. These programmatic elements were used as …

A Grounded Theory of Creative Identity
… collaboration, and reward. A constructivist grounded theory design was employed to examine the meaning of being a creative individual and the associated creative processes utilized by the self-identified participants. The data collected were used to develop a theory of creative identity for …

Grounded Language Learning with Foundation Models
… pretrained on unstructured text can develop some grounded understanding such as accurately capturing perceptual qualities eg. colours of objects. This suggests that large-scale text compression may offer a pathway to learning grounded knowledge. Yet this raises a deeper question: is text-only …

Grounded semantic parsing using captioned videos
… develop a semantic parser which is trained in a grounded setting using pairs of videos captioned with sentences. This setting is both data-efficient requiring little annotation and far more similar to the experience of children where they observe their environment and listen to speakers. The …

Language Modeling from Visually Grounded Speech
… modeling techniques directly from visually grounded speech. We first introduce the Audio-Visual Neural Syntax Learner (AV-NSL), an unsupervised parser that recovers constituency trees directly from raw speech paired with images, demonstrating how visual context effectively bootstraps grammar …

Technological Immersion Learning: A Grounded Theory
… Theory (TILT) was developed through a classic grounded theory study in the seminal tradition of Glaser and Strauss (1967) and Glaser (1978, 1992, 1998, 2001, 2007). The purpose of the study was to investigate an exemplary case of self-determined technology enthusiasts in the hopes of generating …

Developing Computational Thinking Through Grounded Embodied Cognition
Two studies were conducted to examine the use of grounded embodied pedagogy, construction of Imaginary Worlds (Study 1), and context of instructional materials (Study 2) for developing learners' Computational Thinking (CT) Skills and Concept knowledge during the construction of digital artifacts …

European integration reassessed: a grounded theory approach.
… themselves in the creation of the EU. Through grounded theory methodology, an empirical study of the European life insurance industry in general and of the Third Life Assurance Directive in particular, this thesis investigates the extent of sector involvement in the EU's decision-making …

Evaluating visually grounded language capabilities using microworlds
… unifying a range of abilities around visually grounded language understanding in a single problem statement. It has also been an early example for which some of the aforementioned issues were identified. To illustrate the new evaluation approach, this thesis introduces ShapeWorld, a diagnostic …

Building grounded abstractions for artificial intelligence programming
Most Artificial Intelligence (AI) work can be characterized as either "high-level" (e.g., logical, symbolic) or "low-level" (e.g., connectionist, behavior-based robotics). Each approach suffers from particular drawbacks. High-level Al uses abstractions that often have no relation to the way real, …

Grounded Situation Models for Situated Conversational Assistants
… blackboard" representational structure called a Grounded Situation Model (GSM), which is closely related to the cognitive psychology notion of situation models. The GSM serves as a workspace with contents similar to a "theatrical stage" in the agent's "mind". The GSM may be filled either with the …

Neural techniques for modeling visually grounded speech
In this thesis, I explore state of the art techniques for using neural networks to learn semantically-rich representations for visual and audio data. In particular, I analyze and extend the model introduced by Harwath et al. (2016), a neural architecture which learns a non-linear similarity metric …

Appreciative Inquiry Practitioner Formation: A Grounded Theory Study
… in organizations (Ruona & Lynham, 1999). This grounded theory study addressed the question: What is the development journey of AI practitioners? The study introduced a theoretical framework for AI practitioner formation. The findings and discussion from this study suggest that AI formation …

Cancer screening behaviors in older adults: Grounded theory
… and primary purpose of the study. Generation of grounded theory regarding older adults' beliefs and perceptions about cancer screening was the ultimate goal. Formal, unstructured interviews were completed with fifteen older adults who had completed a cancer screening examination and had not …

Mobile Health Supporting Physical Activity: A Grounded Theory
… aim was to develop a substantive theory using grounded theory methodology with a constructivist theoretical stance which guided all sampling and analytical procedures, assisted by the software QSR-NVivo. Participants contributed 34 in-depth, semi-structured interviews (22 purposive and 12 …

Visual analysis and synthesis with physically grounded constraints
… scene. I show how we can incorporate physically grounded constraints such as scene-specific geometry in a non-parametric optimization framework for (1) revealing the missing parts of an image due to removal of a foreground or background element, (2) recovering high spatial frequency details that …
