their smoking choices. I find that US elderly tend to over-emphasize the importance of their genetic makeup but … underestimate the influence of their health-related choices, such as smoking, on their longevity. This finding can partially explain … effects of their genes and health-related choices on their longevity, then the average smoking rate for the age group analyzed …

This paper utilizes the theory of compensating differentials for job risks from the laboreconomics literature to evaluate farmers’ differences in wage-risk tradeoffs. In thecontext of job risks, the theory predicts that farmers who place a lower value on healthstatus are willing to work for...

This paper examines the changes in nutritional behavior of Russian adults over the ten-year transition period, between 1994 and 2004. We present evidence on the impact of individual as well as regional characteristics on changes in fat, protein, alcohol and cigarette consumption, and on...

Recently, researchers have reformulated Item Response Theory (IRT) models into multilevel models to evaluate clustered data appropriately. Using a multilevel model to obtain item difficulty and person ability parameter estimates that correspond directly with IRT models’ parameters is often...

Item Response Theory (IRT) models are the basis of modern educational measurement. In order to increase testing efficiency, modern tests make ample use of groups of questions associated with a single stimulus (testlets). This violates the IRT assumption of local independence. However, a set of...

This dissertation compares the parameter estimates obtained from two item response theory (IRT) models: the 1-PL IRT model and the MC1-PL IRT model. Several scenarios were explored in which both unidimensional and multidimensional item-level and personal-level data were used to generate the item...

Broadening the term augmented testing to include a combination of multiple measures to assess examinee performance on a single construct, the issues of IRT item parameter and proficiency estimates were investigated. The intent of this dissertation is to determine if different IRT calibration...

As item response theory (IRT) has developed and is widely applied, investigating the fit of a parametric model becomes an important part of the measurement process when implementing IRT. The usefulness and successes of IRT applications rely heavily on the extent to which the model reflects the...
