Abstract
The New Faculty Preparation Survey was designed to measure perceptions of recently hired faculty regarding research, service, and teaching for self and institution, while considering academic preparation. A Rasch measurement model was applied to the calibration sample responses to evaluate the psychometric properties of the instrument, providing a foundation for structural modifications. Rasch results revealed sound reliability; however, item misfit existed, coupled with limited utility of the full rating scale. Studying the measurement properties of the instrument will aid in proper interpretation of the results and in the construction of an instrument that can be used by higher education institutions to better understand faculty, and potentially to enhance programmatic structuring. Accurately measuring and understanding faculty perceptions across research, service, and teaching can aid in professional development training at the university level, future faculty preparation, and general faculty satisfaction.

Impact of Military Expenditure on Domestic Economy: A CGE Modelling Approach for India
The parameter values of a CGE model are computed using a method known as calibration, which enables to generate base year equilibrium values or short run solution. Method of calibration relies on the assumption that the economy is in Equilibrium. This is established by invoking a benchmark dataset to represent equilibrium for the economy in such a manner that the model is actually solved from the dataset for its parameter values. In our analysis benchmark dataset is represented by our constructed SAM. Equilibrium exists because the SAM is a square matrix whose row and column sum for a given account are equal. In the first stage we have to choose functional form for our model which is based on our model assumptions discussed in the previous section. Model equations are supplied with the data in the second stage so that all parameter and variable values are adjusted with corresponding SAM values.
