Over the past 25 years California has transformed its system of public school finance from one of the least equitable in the nation to one of the most equitable. This paper examines the impact of that transformation on housing values. Specifically, we use data on residential housing sales from Los Angeles County for the years 1975, 1980, 1985, and 1990, to answer three fundamental questions rel...

Production leveling is an essential element of the Toyota Production System. It aims at balancing production volume as well as production mix to reduce waste, overburden, and unevenness. The application of conventional leveling approaches is limited by the requested product diversity. Because of this production leveling is predominantly used in high volume production. Nevertheless it can be imp...

resource allocation and optimal leveling are among the top challenges in project management. this paper presents a dea-based procedure for determining an optimal level of inputs to produce a fixed level of outputs. to achieve this goal, we assume that the levels of outputs can be forecasted in the next season and the procedure will determine optimal level of inputs for all dmus. such as some of...

Resource Planning and Leveling are two critical areas of resource management which need to be implemented by contractors aid in construction project execution. However, the process undertaking these processes their projects, meet a number challenges discourage them from implementing Leveling. Nonetheless, has benefits may not known some contractors. The purpose this research therefore was estab...

In this work, the thermal stabilities of a series of polyethylene glycols (PEG 4000, 6000 and 10000) were investigated after compositing with different kinds of inorganic salts, such as ammonium molybdate tetrahydrate (AMT), NH4VO3, (NH4)2SO4, NH4NO3, Na2SO4, Na2MoO4. It was first observed that all the ammonium salts exerted leveling effects for the thermal stabilities of the PEGs. In other wor...
