A SPATIAL AND TEMPORAL AUTOREGRESSIVE LOCAL ESTIMATION FOR THE PARIS HOUSING MARKET

ABSTRACT This original study examines the potential of a spatiotemporal autoregressive Local (LSTAR) approach in modeling transaction prices for the housing market in inner Paris. We use a data set from the Paris Region notary office (Chambre des notaires d’Île‐de‐France) which consists of approximately 250,000 transactions units between the first quarter of 1990 and the end of 2005. We use the exact X–Y coordinates and transaction date to spatially and temporally sort each transaction. We first choose to use the STAR approach proposed by Pace et al., 1998 . This method incorporates a spatiotemporal filtering process into the conventional hedonic function and attempts to correct for spatial and temporal correlative effects. We find significant estimates of spatial dependence effects. Moreover, using an original methodology, we find evidence of a strong presence of both spatial and temporal heterogeneity in the model. It suggests that spatial and temporal drifts in households socio‐economic profiles and local housing market structure effects are certainly major determinants of the price level for the Paris Housing Market.

古代中国人造蓝紫硅酸铜钡颜料

这篇文章是对四件附着有硅酸铜钡颜料的中国古代器物的研究。其中三个样品是彩陶颗粒,来自甘肃省张家川马家源遗址,它属于战国晚期（474-221BC）。另外是对山东章丘威山汉墓壁画上的（206BC-8AD）单个晶体的单独研究。一个彩陶颗粒样品和单个晶体表明有中国深蓝（BaCu2Si2O7）存在,这是一关于硅酸铜钡的新发现。相对于已知道中国蓝（BaCuSi4O10）和中国紫（BaCuSi2O6）,这种BaCu2Si2O7成分被称为中国深蓝,该彩陶颗粒的颜料层也含有中国蓝中国紫。还运用了SEM和EDX对其表面形态的分析和通过拉曼光谱对中国蓝、中国紫元素成分的分析。x射线对单个晶体的分析知道了BaCu2Si2O7化合物的结构。通过现代仪器的综合分析研究,推断前期硅酸铜石英相谱图,白色Ba2CuSi2O7成分,仅有很小的可能性在历史遗迹中找到该颜料。
