OBJECTS We carried out an investigation to clarify the real state of indoor air pollution by chlorpyrifos (termiticide) and exposure to chlorpyrifos of residents by measuring its urinary metabolite 3,5,6-trichloro-2-pyridinol (TCP) as an exposure index, such as biological monitoring. METHODS The investigation was conducted in 43 individual houses with termiticide application (whether the term...

Composite samples of freshly voided excreta from 91 poultry houses were tested qualitatively for Salmonella; 26 (29%) were positive. The houses were located on 36 farms, 18 of which (50%) yielded one or more positive samples. In a separate, quantitative study, Salmonella densities ranged from less than 1 to over 34,000 per g of excreta (dry weight). High densities were noted in waste from cage ...

Housing allocation problems deal with assigning indivisible objects (houses) to agents who have preferences over these objects. We examine the housing allocation problem with existing tenants, then with both new and existing tenants. In both cases, we present and evaluate an algorithm for assigning houses. We then consider a version of the housing allocation problem where agents are grouped int...

OBJECTIVES To assess whether HOUSES (HOUsing-based index of socioeconomic status (SES)) is associated with risk of and mortality after rheumatoid arthritis (RA). DESIGN We conducted a population-based case-control study which enrolled population-based RA cases and their controls without RA. SETTING The study was performed in Olmsted County, Minnesota. PARTICIPANTS Study participants were ...

PURPOSE We present the concept of the Green House, articulated by William Thomas as a radically changed, "deinstitutionalized" nursing home well before its first implementation, and we describe and discuss implications from the first Green Houses in Tupelo, Mississippi. DESIGN AND METHODS Green Houses are small, self-contained houses for 10 or fewer elders, each with private rooms and full ba...

Background Sober living houses (SLHs) are peer-managed residences that require sobriety and household participation among residents who rent rooms on a monthly (indefinite) basis and otherwise live normal lives according to personal schedules and needs. The houses do not provide counseling or services, but regular attendance at 12-step or other types of mutual-help groups is generally required....

I construct a dynamic stochastic general equilibrium (DSGE) model in this paper to study the fluctuations in the U.S. housing markets. The model features a market for newly built houses, a secondary market for old houses, and an endogenous term structure of nominal interest rates. Negative technological progress in the housing sector explains the upward trend in house prices over the past four ...

The effectiveness of three operational strategies for the control of Triatoma dimidiata was compared by a field trial in the Department of Madriz, Nicaragua. One strategy involved full pretrial evaluation, followed by spraying of all houses irrespective of whether or not they had been found to be infested. The second strategy minimised the pretrial evaluation by considering the locality infeste...
