Essays in the Economics of Aging
… receiving health insurance through an employer. Previous studies have tried to determine whether EPHI reduces job mobility. However, these studies provide conflicting evidence on the significance and magnitude of job-lock. Chapter Three uses data from the HRS to show the degree to which omitted …

Body image in middle school students
… population had a higher level of body image than previous studies indicate. It also showed that students at this age are engaging in weight-control behaviors. The major influences on body image and weight-control behaviors were found to be peers and the media. This research, along with previous …

Validity of an assessment centre as a measure of competency ratings for development in a large financial institution
… this measure is yet to be fully ascertained as previous studies have shown that although assessment centres have predictive validity, they lack construct validity. The research study therefore set out to establish whether assessment centres used within financial institutions have predictive …

Variation in silicosis prevalence in South African gold miners : an industry-wide study
… since its inception in 1887. There have been two previous studies conducted in black in-service miners using modern epidemiologic methods that found high prevalences of silicosis .The objectives of our study were three-fold. Firstly, to determine silicosis prevalence stratified by certain …

Rock hyraxes (Procavia capensis) and their environments : δ13Ccollagen and δ15Ncollagen as environmental indicators
… at South African archaeological sites. Previous studies have focused on their remains as proxies for aspects of diet and mobility in prehistoric human populations. They have also been recognized as valuable palaeoenvironmental indicators due to the fact that their stratified communal …

Female Mate Selection for Long-Term Relationships
… select partners who are similar to themselves. Previous studies have shown that individuals do tend to select partners who are similar in age, ethnic background, religion, socioeconomic status, psychological characteristics and personality characteristics. In this study the data supports …

Sequential lineups reduce unconscious transference and mistaken lineup identification: but at what cost?
… that was small in magnitude when compared to previous studies. Experiment 2 used the same materials and procedures, except the bystander was replaced in the lineup with the thief. Sequential lineups decreased the rate of correct identifications when compared to previous studies that used …

Evaluation of the dynamic characteristics of the K-Gill anemometer
… and a non-cosine behavior, as shown in previous studies (Ataktürk, 1988; Pond et al., 1979). The turbulence energy spectra from the field test revealed that the propeller anemometer behaves like a single-pole low-pass RC filter, as suggested in previous studies (Ataktürk, 1988; Pond et …

Derivation of an Evolution Equation for Two-Dimensional Waves on Thin Films
… thin liquid layer on a planar incline. Following previous studies, the Marangoni effect is incorporated by a constant surface tension gradient and yields a non-convex flux function in our thin film equation. We extend previous studies by deriving the thin film equation governing two-dimensional …

The trend of wind speed over the United States during 1998 - 2011
… at the upper levels, which is consistent with previous studies. The decreasing trend of near-surface wind speed is statistically significant (p<0.01). However, the statistical significance of the decreasing trend drops with increases in altitude. We identified a largest negative trend in wind …

Identifying Signatures of Plasma Waves and Reconnection Associated with Kelvin-Helmholtz Activity
… of plasma transport into the magnetosphere. Previous studies have shown that there exists a temperature asymmetry in the plasma sheet. During northward IMF, the cold component ions are 30-40% hotter in the dawn flank plasma sheet compared to the dusk flank. However, the mechanisms responsible …

Shear lag in truss core sandwich beams
… stiffness of truss core sandwich beams. In previous studies, the measured values of stiffness in loading have proven to be 50% of the theoretical stiffness during three point bending tests. To test the effect of shear lag on this phenomenon, the beams' dimensions were altered to decrease the …

The term structure of zero-coupon and coupon bonds: a comparative analysis
… bonds parallels the behavior of coupon bonds. Previous studies have demonstrated that there are synchronous changes among different maturities of coupon bonds. Results of statistical and sign tests are used to measure the degree of synchronicity, the relative amplitude of change and the amount …
