How Are Interannual Variations Of Land Surface Phenology In The Highland Pastures Of Kyrgyzstan Modulated By Terrain, Snow Cover Seasonality, And Climate Oscillations? An Investigation Using Multi-Source Remote Sensing Data, Monika Anna Tomaszewska

Electronic Theses and Dissertations

In the semiarid, continental climates of montane Central Asia, with its constant moisture deficit and low relative humidity, agropastoralism constitutes the foundation of the rural economy. In Kyrgyzstan, an impoverished, landlocked republic in Central Asia, herders of the highlands practice vertical transhumance—the annual movement of livestock to higher elevation pastures to take advantage of seasonally available forage resources. Dependency on pasture resource availability during the short mountain growing season makes herds and herders susceptible to changing weather and climate patterns. This dissertation focuses on using remote sensing observations over the highland pastures in Kyrgyzstan to address five interrelated topics: (i) …

“It’S Hard To Get Your Head Around Something Like This”: Figurative And Intense Language For Sensegiving During Severe Weather Coverage, Robert W. Prestley Jan 2019

“It’S Hard To Get Your Head Around Something Like This”: Figurative And Intense Language For Sensegiving During Severe Weather Coverage, Robert W. Prestley

Theses and Dissertations--Communication

During high-impact weather events like Hurricane Harvey, broadcast meteorologists take on the role of sensegiver, as they develop frameworks to help their viewers make sense of the storm. These frameworks are communicated through rhetorical choices evident in the language the meteorologists use to describe the storm’s threat and impact. This study investigates the rhetorical choices of KHOU broadcast meteorologists during Hurricane Harvey in order to make sense of the disaster, using an inductive thematic analysis. The results indicate that the KHOU broadcasters framed Harvey figuratively as an all-encompassing monster and a heat-seeking machine. The meteorologists used emotionally intense language to …

Legislation To Reduce Microplastic Pollution : Understanding The Factors That Facilitated Passage Of The Federal Microbead-Free Waters Act Of 2015, Alyson Kelly Northrup

Legacy Theses & Dissertations (2009 - 2024)

The full environmental impacts of microplastic pollution in aquatic environments remain uncertain, but several detrimental effects have been documented, including adverse health effects in multiple species and the susceptibility of microplastics to adsorb toxins and leach plastic additives. Plastic microbeads from rinse-off personal care products are a source of microplastic pollution that is introduced directly into the environment through runoff, including wastewater treatment plant effluent. In December 2015, the federal Microbead-free Waters Act of 2015 banned the manufacture and sale of all rinse-off personal care products containing plastic microbeads in the United States.

Emotion Forecasting In Dyadic Conversation : Characterizing And Predicting Future Emotion With Audio-Visual Information Using Deep Learning, Sadat Shahriar

Legacy Theses & Dissertations (2009 - 2024)

Emotion forecasting is the task of predicting the future emotion of a speaker, i.e., the emotion label of the future speaking turn–based on the speaker’s past and current audio-visual cues. Emotion forecasting systems require new problem formulations that differ from traditional emotion recognition systems. In this thesis, we first explore two types of forecasting windows(i.e., analysis windows for which the speaker’s emotion is being forecasted): utterance forecasting and time forecasting. Utterance forecasting is based on speaking turns and forecasts what the speaker’s emotion will be after one, two, or three speaking turns. Time forecasting forecasts what the speaker’s emotion will …
