Analysis of designed and emergent consequences of mobile banking usage by SME’s in Kenya using ethnographic decision tree modeling
… and emergent consequences. Ethnographic decision tree modelling (EDTM) which is a cognitive research methodology was feasibly employed to obtain the adoption and usage decision criteria from which quantifiable and non-quantifiable consequences were then inferred. Structuration theory was used as a …

Petri net modeling of fault analysis for probabilistic risk assessment
Fault trees and event trees have been widely accepted as the modeling strategy to perform Probabilistic Risk Assessment (PRA). However, there are several limitations associated with fault tree/event tree modeling. These include 1. It only considers binary events; 2. It assumes independence among …

Reliability-based nuclear power plant maintenance resource allocation in order to reduce unfavorable operational publicity
… systems did not. Risk analysis with fault tree modeling was carried out to quantify risk of major components in turbine-generator systems, and in nuclear steam supply systems. The risk was evaluated in terms of the frequency of unplanned shutdowns in order to identify which components are …

Understanding acceptance decisions and identity associated with smartphones: A qualitative enquiry
… smartphones. Employing ethnographic decision tree modeling, this study proposed a model for smartphone acceptance. Using social identity theory as the analytical lens and qualitative content analysis as the research technique, Study 3 examined the ways social identities are formed based on …

Associations Among End-Of-Life Discussions, Healthcare Utilization And Costs, And Race/ethnicity In Persons With Serious Illness
… regression and classification and regression tree modeling (Chapter 4) showed a complex set of variable interactions were associated with PCC timing before death. Results imply need for investment in PCC across racial groups.

Quantification of the Effectiveness of Agricultural Riparian Buffers to Protect Stream Health in Maryland's Coastal Plain and Piedmont Regions
… by buffer presence, type and width. Regression tree modeling was able to delineate a range of minimum effective buffer width between 22-38 meters. All measures of stream health in Piedmont systems were controlled by hydrology and geomorphology. Therefore, insofar as buffers can mediate …

Delination of Coastal Shark Habitat within North Carolina Waters Using Acoustic Telemetry, Fisher-Independent Surveys, and Local Ecological Knowledge
… At the estuarine scale, boosted regression tree modeling of shark catch and environmental data from North Carolina Division of Marine Fisheries (NCDMF) gillnet and longline surveys were used to spatially delineate potential habitat for six species within Pamlico Sound. Inlet distance and …

Avian assemblages and Red-eyed Vireo nest survival within mineland forest
… groundcovers. Despite potential differences in tree species composition, study of the relationship between habitat structure and the avian assemblage within pre-SMCRA mineland forest could provide insight into the species assemblages that future mineland reforestation efforts might yield. Study …

Combined use of airborne laser scanning and hyperspectral imaging for forest inventories
… main topics: the development of new individual tree segmentation algorithms, the assessment of direct and indirect dendrometry methods, tree species classification based on ALS and HI features. A common dependency of these topics is the availability of reliable reference datasets for the …

Feasibility, effectiveness, budget impact and surveillance of partner services for HIV in Kenya
… due to aPS were generated through decision tree modeling. We estimated a range, where the lower-bound cost assumed that all sexual partners tested were HIV-negative and the upper-bound cost assumed that all sexual partners were HIV-positive. All costs were undiscounted and reported …
