Rapid endangered species assessment : a novel approach to improve extinction risk assessments in poorly known species

Creator:: Bianchi, Carlos A.
Abstract:: The number of endangered species is rapidly increasing while paucity of adequate information and resources delays establishment of conservation actions. The IUCN’s listing system is insufficient to determine conservation priorities and many species lack information even to be evaluated (i.e., “data deficient”). Here I proposed and tested the Rapid Endangered...

Survival Assessment, Inactivation Kinetics Models, and Farm-to-Table Quantitative Risk Analysis of Food Pathogens

Creator:: Deng, Kai
Abstract:: About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...

Impact of parameter variability on the food process engineering calculations required for safety, quality and shelf-life estimations

Creator:: Chotyakul, Nattaporn
Abstract:: Quantitative procedures were developed to determine the effect of variability in the model parameters required for the estimation of microbial shelflife and thermal processing time. Monte Carlo simulations combined with these predictive models were implemented in Microsoft Excel™. In the first study, predictive models were used for shelf-life predictions based...

Reasons Behind the Low Enrollment of Women in Computer Science

Creator:: Schneider, Ashley R.
Abstract:: Over the past few decades, the ratio of women to men in many traditionally maledominated fields has become much more equal. However, in science, technology, engineering, and math (STEM) fields the ratio has not improved at the same rate. In computer science the ratio is still very uneven. Today women...

Long-term Effects of Vegetation Management on Biomass Stock and Aboveground Net Primary Productivity of Four Coniferous Species in the PNW

Creator:: Flamenco, Herman N., Jr.
Abstract:: Forest vegetation management (FVM) is an important component of reforestation in the Pacific Northwest (PNW). Several studies have demonstrated the benefits of vegetation management on planted conifer growth and survival. However, few reports have been published on the long-term effects of FVM treatments on total ecosystem biomass accumulation and aboveground...

An Investigation of the Effects of Merge Conflicts on Collaborative Software Development

Creator:: Brindescu, Caius
Abstract:: Merge conflicts have long plagued software development. With larger and more dispersed teams comes greater risk of developers working on the same code at the same time. While merge conflicts are known to be painful, their exact impact on software is still largely unknown. Are merge conflicts an isolated problem,...

Hierarchical graphical models for activity recognition in videos

Creator:: Amer, Mohamed R.
Abstract:: This dissertation addresses the problem of recognizing human activities in videos. Our focus is on activities with stochastic structure, where the activities are characterized by variable space-time arrangements of actions, and conducted by a variable number of actors. These activities occur frequently in sports and surveillance videos. They may appear...

Abstract:: In the contemporary United States, the process of "coming out of the closet," or public disclosure of one's non-normative sexual orientation or gender identity, is ongoing and performative. Particularly within the context of dominant contemporary U.S. society, popular media favors a hegemonic set of defining characteristics, which thereby forces the...

Effects of volcanic and hydrologic processes on forest vegetation: Chaitén Volcano, Chile

Creator:: Swanson, Frederick J., Jones, Julia A., Crisafulli, Charles M., and Lara, Antonio
Abstract:: The 2008-2009 eruption of Chaitén Volcano (Chile) involved a variety of volcanic and associated hydrologic processes that damaged nearby forests. These processes included coarse (gravel) and fine (silt to sand) tephra fall, a laterally directed blast, fluvial deposition of remobilized tephra, a variety of low-temperature mass-movement processes, and a pyroclastic...

Interactive visualization of diversity in multivariate data sets unified across fields of study

Creator:: Pham, Tuan N. T.
Abstract:: The study of the diversity of multivariate objects shares common characteristics across disciplines, including ecology and organizational management. Nevertheless, experts in these two disciplines have adopted somewhat separate diversity concepts and analysis techniques, limiting the ability of potentially sharing and cross comparing these concerns. Moreover, while complex diversity data may...
