Despite years of research into human computer interaction (HCI), the environments programmers must use for problem-solving today—with separate modes and tools for writing, compiling, testing, visualizing, and debugging— derive their basic structure from historical accident, and take little advantage of HCI research into the cognitive issues of programming. Neglecting these...
Declarative visual programming languages (VPLs), including spreadsheets, make up a large portion of both research and commercial VPLs. Spreadsheets in particular enjoy a wide audience, including end users. Unfortunately, spreadsheets and most other declarative VPLs still suffer from some of the problems that have been solved in other languages, such...
Although spreadsheets can be argued to be the most widely-used end-user programming languages today, they are very limited compared to other programming languages, supporting only a few built-in types and offering only primitive support for code reuse. The inheritance mechanisms of object-oriented programming might seem to offer help for the...

Otoferlin is a protein that is essential in the process of hearing. Mutations in otoferlin are associated with profound recessive deafness. The long-term goal of the Johnson lab is to understand how otoferlin contributes to hearing and why certain mutations result in deafness. This project sought to characterize the difference...
The commercial groundfish fishing industry and groundfish research have a long concurrent history of activity on the Oregon continental margin. Within the non-whiting groundfish fishery, the target species are primarily flatfishes, sablefish, lingcod, and rockfishes, though landings of each have fluctuated over time. Recent work shows that over the past...
Nursery-grown seedlings are critical for attaining reforestation and restoration success in many ecosystems, including mixed-conifer forests in the Northwest, which is the native range for Douglas-fir (Pseudotsuga menziesii). Seedling establishment after planting depends on coordinated responses in seedling growth, physiology, and hydraulic function. The chapters in this dissertation review growth...
Budburst, the initiation of annual growth in plants, is sensitive to climate variation and is therefore used to monitor physiological responses to climate change. Budburst timing can vary between regions of an individual tree, but this phenomenon it is unaccounted for in current monitoring efforts and may contribute to the...
