Calcium Requirement Distribution Via Bone Growth Modeling
… on estimating calcium requirements using bone growth data in adolescents. We estimate the peak rate of growth of bone and the variability of this peak growth rate to provide Dietary Reference Intakes (DRIs) for calcium. The specific DRIs of interest are Estimated Average Requirement (EAR) and …

RPK growth modeling for passenger airlines using network-related variables
… variables that allow to forecast the RPK growth of an airline in the following 7 years. Most of the available forecast for air passenger traffic focus on economic variables such as fuel price, GDP of the countries, trade index and population among others. This project wanted to explore if …

Comparison of Event History Analysis and Latent Growth Modeling for College Student Perseverance
Event history analysis is the most prevalent modeling technique used to model event occurrence with longitudinal data (Cox & Oakes, 1984; Menard, 1991; Singer & Willett, 1993, 2003). An alternative is to model longitudinal data within the SEM framework, known as latent variable growth modeling …

Women's body image throughout the adult life span: Latent growth modeling and qualitative approaches
… analysis for quantitative data, latent growth model (LGM) analysis for hypothesis testing, and qualitative data analysis for open-ended responses. Increasing trajectories were found in women's perceptions about their actual body shape, ideal body shape, and actual/ideal body image …

Capturing Latent Abilities and Latent Capacities of Professional Golfers Using Nonlinear Mixed Effects Growth Modeling
… golfers. I used nonlinear mixed effects growth modeling (e.g., Dynamic Measurement Modeling) to measure professional golfers’ ability levels and capacities for improvement. I accomplished this using a two-stage modeling approach. First, a crossed linear mixed effects model estimated each …

A Dynamic Approach of Turnover Procedure: It's About Time and Change
… of statistical analyses, survival analysis and growth modeling, are applied to assess questions that arise from the longitudinal turnover perspective, such as questions surrounding whether and when turnover occurs or questions surrounding the systematic changes of the relationship between …

Theoretical study of MBE growth of indium gallium arsenide semiconductor compound on gallium arsenide substrate
… an experiment with the same conditions. Growth modeling investigates compound semiconductor characteristics during the MBE growth which can achieve the best results to control the quality of growth. Growth modeling also is less expensive and faster than experiments. The wide variation in …

The consequences of ignoring assessment date heterogeneity within waves for latent growth models
In traditional latent growth modeling, researchers assume that assessment dates within waves from longitudinal studies are homogeneous, although they are nearly always heterogeneous. In this study, we present a pedagogical illustration of assessing the consequences of ignoring time-point …

Living On Borrowed Time: A Longitudinal Examination of a Time-Limited Housing Voucher Program
… living in poverty. Using Hierarchical Linear Modeling (HLM) the first analysis addresses what can be predictive of socioeconomic status for families. A second set of analyses were preformed, using both cross-lagged and latent growth modeling, to assess the interconnected nature of resilience …

The Experience of Mindfulness for Children with Autism: An Examination of Self-Report and Electrodermal Response
… for children with autism (N = 35). Multilevel growth modeling revealed that greater mindfulness enjoyment was predicted by higher autism symptoms, greater child motivation to participate in therapy and greater child worry dysregulation. Greater computer enjoyment was predicted by greater child …

Heat transfer through a condensate droplet on hydrophobic and nanostructured superhydrophobic surfaces
… In this thesis, we reconcile classical droplet growth modeling barriers by utilizing two-dimensional axisymmetric numerical simulations to study individual droplet heat transfer on non-wetting surfaces (90° < θ_a < 170°). Incorporation of an appropriate convective boundary condition at the …

Co-development of internalizing and externalizing behaviors during middle childhood and potential moderators of the process
… i.e. parent-child conflicts. Longitudinal growth modeling and longitudinal difference score modeling are used to examine the dynamic relationship and the moderating effects. Comparisons of the two approaches are made with respect to the specific hypotheses of change tested by each model, …

Population Ecology of Invasive Lionfish (Pterois volitans/miles) in the South Atlantic Bight
… Lionfish life history estimates are important to modeling lionfish population growth, modeling future dispersal and evaluating the efficacy of different removal strategies. Since lionfish life history will vary with a suite of environmental, biological and ecological factors, estimates of lionfish …
