A Population-Level Approach to Dementia Risk Reduction
… living with dementia is projected to rise as the population ages. Despite advances in our understanding of the disease, treatment options remain limited. Evidence from the past decade or so has indicated that dementia risk can be lowered at the population level, and several modifiable risk factors …

Enhancing meta-heuristic algorithms using center-based sampling at population level
… can be utilized at either the operation and/or population levels. Despite the overall efficiency of the center-based sampling in population-based algorithms, utilization at the operation level requires customizing the strategy for a specific algorithm which degrades the scheme’s generalization. …

Population-level determinants of obesity in Canada: application of econometric techniques
… and government policy are jointly identified as population-level determinants of obesity that have resulted in its rapid growth. While these population-level determinants have been identified as important, their impact has not been explicitly quantified in Canada. The geographic distribution of …

Characterizing population-level variation in mRNA splicing and implications for human genetic interpretation
… triggers a change in function, happening at the level of a cell, organism, or of fitness. The consequences of splicing variability, and the contribution of genetic variation to this process, remains incompletely characterized. In this thesis, we seek to characterize the splicing events …

Population-Level Differences in Pinus monophylla Whole-Plant Seedling Strategies Under Varying Precipitation Pulses
… reflecting adaptation to local environments. Populations may vary in traits that regulate seedling growth and resource acquisition in response to resource pulse regimes, and some adaptations to historic conditions may become maladaptive under projected climate scenarios. Singleleaf pinyon pine …

Impacts of population-level reproductive success on recruitment dynamics in largemouth bass (Micropterus salmoides)
… the mechanisms that govern recruitment in fish populations is fundamental to informing management decisions that are designed to provide sustainable recreational fisheries. The Largemouth Bass (Micropterus salmoides) is a popular and widely exploited sport fish that provides exclusively paternal …

POPULATION LEVEL CONDITIONS AS SIGNALS OF ENTREPRENEURIAL OPPORTUNITIES: A COGNITVE SYNTHESIS OF THE ENTREPRENEURIAL TRAITS AND POPULATION RATES PERSPECTIVES
… perspective implicitly suggests that population level founding rates, dissolution rates, and density levels influence the likelihood that entrepreneurs will launch new ventures within a given population domain. The central idea is that population rates and densities may act as signals …

Neurochemical Levels Correlate with Population Level Differences in Social Structure and Individual Behavior in the Polyphenic Spider, <em>Anelosimus studiosus</em>.
… with Electrochemical Detection to quantify levels of these neurochemicals among adult females from social (multi-female) and solitary (single-female) webs in east Tennessee. A subset of spiders was scored for individual social tendency. We found that higher octopamine levels are associated …

A Toxicological Analysis of Exposure Magnitude, Duration, and Frequency and the Significance for Monitoring and Management of Episodic Pollution Events
Information on organism and population effects was then expanded through the use of toxicity and population modeling. Several toxicity models were evaluated against organism effects of single and multiple exposures and appropriate models were used to expand the analysis of organism effects to …
