Growth Curve Analysis of Soybean Cultivars
To study the methodology for functional growth analysis of soybean and to find out the growth characteristics of soybean cultivars, two experiments were conducted at the Agronomy Plant Pathology South farm of the University of Illinois during the years 1985 and 1986.

Gender differences in symptom change for court-placed youth in residential treatment : a latent growth curve analysis
… symptom severity every four weeks. Latent Growth Curve Modeling (LGCM) was implemented to obtain growth trajectories of symptom change over time. The hypothesis that females would enter residential treatment with greater psychopathological symptoms was supported; however, no gender …

A Latent Growth Curve Analysis of Peer Difficulties, Self-Perceptions, and Peer Beliefs: Links to Psychological and School Adjustment
… avoidance were examined. Findings from latent growth curve analyses supported the contention that relational stressors are related to externalizing problems through more hostile peer beliefs and are associated with internalizing and school adjustment difficulties through maladaptive self and …

A Growth Curve Analysis Study Examining the Relationship Between a Meditation-Based Stress Reduction Program and Components of Subjective Well-Being
Using growth curve analysis (Francis et al., 1991; Rogosa, Brandt, & Zimowski, 1985), this study tested a model for the experience of beginning meditators. I posited that a successful novice meditator, over the course of a six-session Meditation-Based Stress Reduction Program, would experience an …

Mental health policy outcomes: an examination of older adults' mental health service use, 2002-2012
… years. This dissertation conducted a multilevel growth curve analysis in order to examine older adults’ MHS use using a large, nationally-representative panel survey (the Medical Expenditure Panel Survey – Household Component, or MEPS-HC). We considered MHS use in the MEPS-HC for the period of …

Peer victimization across the school years: consequences for middle school social goals
… the hypothesis that early (2nd grade) and growth in (2nd – 7th grade) peer victimization would predict lower levels of mastery goals and elevated levels of performance approach and avoidance goals in the 7th grade. Longitudinal growth curve analysis was employed in a diverse sample of 636 …

Osteohistology and Growth of Edmontosaurus and Assessment of Life History Changes in Hadrosaurid Dinosaurs
… new data and methods to investigate ontogenetic growth and test life history strategies in hadrosaurid populations from the Late Cretaceous of North America, with a particular emphasis on the integration of osteohistological methods with limb growth and size frequency distributions for inferring …

EXPOSURE TO DOWNSIZING: A LONGITUDINAL EXAMINATION OF CHANGE IN COLLECTIVE TRUST
… collective trust over time using a Latent Growth Curve Analysis (LCA). LCA allowed us to determine the trajectory of collective trust when downsizing occurs which we found to be nonlinear with diminishing returns. We found collective trust initially decreases in time period two but shows a …

Investigation of mycobacterial cell wall genes and their requirement for survival in immune related stressful conditions
… not to rifampicin, isoniazid and ethambutol. Our growth curve analysis showed that ftsEX and ripC are not essential for survival in normal growth conditions. However, ftsEX and ripC are conditionally essential for M. smegmatis in low salt media. Growth defects in this condition were characterized …

Using Disability Rating Scale Recovery Curves to Predict PASAT Performance After Closed Head Injury
… attention, and working and immediate memory. . Growth curve analysis was used to fit individual growth curves to the DRS scores and then to produce a best-fit recovery curve model. The utility of this model for predicting PASAT scores at six months was determined. Age and severity of injury …

China Twenty Years After: Substance Use Under Rapid Social Changes
… of community change.</p> <p>Using survival analysis, I have found that general drinking protected against unemployment risk for both men and women, while smoking, even heavy smoking, only protected men but penalized women. However, on the other hand, heavy drinking was not a significant …

Identification and characterization of virulence associated factors of C. jejuni
… of the pathogen towards formic acid. Finally, growth curve analysis indicates that these genes are not related to the utilization of formic acid by formate dehydrogenase.A second gene investigated in this thesis with regard to reduced infectivity of C. jejuni isolate B2 is cj0005c, which …

Homing of 111In-Labeled Bone Marrow Mesenchymal Stem Cells in Acute Brain Trauma Model
… doses (0.4-11.1 Bq/cell) of 111In-tropolone, and growth curve analysis, fluorescent activated cell sorter (FACS) analysis after staining with 5-bromo-2-deoxy-uridine (BrdU), and microscopic evaluation after 5-bromo-4-chloro-3-indolyl-D-galactopyranoside (X-gal) staining were performed until the …

An investigation of the impact of the B cell lymphoma factor Activation Induced Cytidine Deaminase (AICDA/AID) on epigenetic plasticity
… Thereafter, proliferation was assessed using growth curve analysis, and WST-1 assay. Growth curves showed that expressing AICDA significantly enhanced cell proliferation. In addition, the WST-1 cell proliferation assay also showed similar results, indicating that AICDA expression promotes cell …
