The Drosophila melanogaster host model

The deleterious and sometimes fatal outcomes of bacterial infectious diseases are the net result of the interactions between the pathogen and the host, and the genetically tractable fruit fly, Drosophila melanogaster, has emerged as a valuable tool for modeling the pathogen–host interactions of a wide variety of bacteria. These studies have revealed that there is a remarkable conservation of bacterial pathogenesis and host defence mechanisms between higher host organisms and Drosophila. This review presents an in-depth discussion of the Drosophila immune response, the Drosophila killing model, and the use of the model to examine bacterial–host interactions. The recent introduction of the Drosophila model into the oral microbiology field is discussed, specifically the use of the model to examine Porphyromonas gingivalis–host interactions, and finally the potential uses of this powerful model system to further elucidate oral bacterial-host interactions are addressed

The Shifting of FHA Discount Points: Actual Vs. Expectations

This study extends the earlier studies by Zerbst and Brueggeman (Z&B) and Colwell, Guntermann and Sirmans (CGS) with regard to the shifting of FHA discount points by the seller to the buyer in the form of a higher selling price. The study extends the earlier studies by reducing the estimation problems of the CGS model and further developing the Z&B model to incorporate expected discount points built into the asking price. The results presented indicate that 100% of the points are not being shifted. Reasons for the less-than-full shifting are given. Copyright American Real Estate and Urban Economics Association.

The Effect of Mortgage Rate Buydowns on Housing Prices:

The model developed in this paper analyzes the effect of builder-financed FHA-VA mortgage subsidies or buydowns on the price of housing. Hedonic pricing equations are estimated for a locationally and qualitatively uniform sample of new tract development homes. The explanatory variables are vectors of physical and financial characteristics. The latter include a continuous variable for discount points paid by builders which is indicative of the magnitude of prepaid finance charges. The results indicate that a substantial portion of mortgage subsidy costs are shifted to buyers in the form of inflated housing prices.

The Effects of Assumption Financing Across Housing Price Categories

This study employs a standard housing valuation model to analyze the capitalization of below-market financing across housing price categories. The study also investigates the effect of secondary financing on housing prices and the effect of the expected holding period on discount capitalization. Using a randomly selected sample of 1981-82 housing transactions the study finds: the discount associated with below-market financing is inversely related to the absolute level of housing prices; secondary financing bears no systematic relationship to housing values; and discount capitalization is inversely related to the expected holding period.
