Greenness and greening: Theoretical and practical implications for promoting subjective well-being
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2026-05-01

Mediterranean forest resilience to drought and climate change
… events are important in driving the canopy greenness loss and recovery. I show that despite increasing aridity, and examples of localised die-back events, Spanish forests are mostly becoming denser, with only 12% of locations analysed declining in greenness over the 18-year study period. …

Woody plant richness and landscape preference
… function in a landscape. This study explores how greenness levels and tree species richness affect preference for neighborhood landscapes. I conducted a systematic assessment of greenness and biodiversity and designed multiple virtual reality landscape simulations as alternatives to traditional …

The effect of spirea aphid (Homoptera: aphididae) feeding and nitrogen fertilization on the growth of young apple trees, with comparisons to apple aphid
… rates, leaf chlorophyll content, and greenness. Pn increased linearly with increasing chlorophyll content and greenness; nitrogen rates caused an increase in Pn and leaf greenness. Aphid-days accumulations were strongly correlated to Pn and greenness at each nitrogen rate applied. …

The impact of megaherbivore grazers on grasshopper communities via grassland conversion in a savannah ecosystem
… of grass height and aerial cover, but not in % greenness or richness of forb species. Grass species varied with locality rather than grazing impact. Total numbers of grasshoppers did not differ significantly between the two contrasting areas (100.2 in vs 93.5 out), however grasshopper species …

Models and Techniques for Green High-Performance Computing
… Toward this end, we seek to improve the greenness of HPC systems by improving their performance per watt at the allocated power budget. In this dissertation, we develop a series of models and techniques to manage power at micro-, meso-, and macro-levels of the system hierarchy, …

Tasks, Skills, and Jobs in the Green Economy
… Processing, we develop a method to quantify the "greenness'' of tasks and occupations. Utilizing this index, we explore the significant role of green skills during economic transitions. Our findings offer a comprehensive roadmap for understanding the evolution of green jobs and skills over the …

Comparing Spatial Measures of the Built Environment for Health Research
… Indiana. Walkability index and vegetation greenness variables were evaluated within 400-meter, 1-kilometer, and 2-kilometer Euclidian and network buffers, census block groups and tracts, and 805- X 805-meter grid cells. Results of analyses using each of these methods to test walkability and …

Neighbourhood Built Characteristics and their Associations with Health-related Fitness in Adults
… built characteristics (walkability and greenness) which included muscular strength and body composition, independent of self-reported physical activity and sedentary behaviour. This study found that neighbourhood walkability may support cardiorespiratory and morphological fitness, …

Greening the chemistry curriculum. To embed the concepts of sustainability and environmental responsibility into the chemistry curriculum in order to equip graduates for future practises in the chemical sciences
… terms of ease of use, applicability and judging ¿greenness¿. It was found that these were not very effective for use within an undergraduate laboratory due to applicability and judging ¿greenness¿, however this work highlighted other areas for improvement. As a result of this work an environmental …

Green space, blue space, & neonatal health: exploring the relationship between environmental factors & birth outcomes in New York City
… green spaces act as measures of residential greenness, while proximity to publicly accessible waterfront areas represents access to blue space. The relationships between these factors and risk of adverse birth outcomes are analyzed through mixed-effects logistic regression models. Individual …

Leveraging the Landsat Archive to Track Understory Evergreen Shrub Expansions in the Coweeta Basin, North Carolina
… the past 36 years analyzing changes in winter greenness using harmonized multi-decadal archives of Landsat imagery. We found the greatest change in winter greenness in relatively dry areas: higher elevations (1275–1300 m), steeper slopes (33°–35°), southward aspects, and far from streams …

Climate-Triggered Drought as Causes for Different Degradation Types of Natural Forests
… indices concerning water content deficit and greenness loss, and their variations were spatially assessed with monthly and inter-seasonal precipitation anomalies from 2000 to 2016. Specifically, dimensions of forest droughts were evaluated in relations with the dimensions of meteorological and …

Integrating remote sensing and terrain data in forest fire modeling
… (TM) remotely sensed data produced brightness, greenness, and wetness images. Image subtraction indicated fire induced change in brightness, greenness, and wetness. Field data guided a fuzzy classification of these change images. Because fuzzy classification can characterize a continuum of a …

Application of Spectral Change Detection Techniques to Identify Forest Harvesting Using Landsat TM Data
… cap brightness differencing, 7) tasseled cap greenness differencing, and 8) univariate differencing using TM band 7. A hybrid method that used the results from the eight previous techniques was developed. After performing the change detection, majority filters using window sizes of 3x3 pixels, …

Remote sensing, normalized difference vegetation index (NDVI), and crop yield forecasting
… relationship between the accumulation of crops’ “greenness” over the growing season and the final crops yield. The ultimate goal of the thesis is to examine whether the NDVI model can produce accurate and timely yield forecasts. Due to the unique features of the spatial data (e.g. global coverage, …

An integrated plant nutrition system (IPNS) for corn and cannabis in the Mid-Atlantic USA
… to varying degrees. In 2017, corn height, NDVI, greenness and vigor were sensitive to the application of these biostimulants in different magnitudes and growth stages, however grain yield and nutrient content were not affected. In combined studies from 2018 and 2019 corn height was not impacted …

The incremental value of smart buildings upon effective rents and transaction prices
… to other so-called "innovation" amenities, like greenness and or fiber-lit connectivity. Results documented in this study suggest that buildings that offer a more integral solution (i.e. buildings that are Smart, Connected and Green) have a premium in both rents and transaction prices over …
