Panel regression models for measuring multidimensional poverty dynamics

This work concerns the study of poverty dynamics and the analysis of the influencing socio-demographic factors. A fuzzy and multidimensional approach has been chosen in order to define two different poverty measures. A panel regression model has been estimated and particular attention has been paid to the treatment of the unobservable heterogeneity among longitudinal units. The specified model combines autoregression with variance components. The empirical analysis has been conducted using the data set of the British Household Panel Survey (BHPS) from 1991 to 1997. This work was co-financed by Murst funds for the projects “Occupazione e disoccupazione in Italia: misura e analisi dei comportamenti”. The paper is the result of the common work of all the authors; in particular G. Betti has written Sects. 2,5.1 and 5.3.1; A. D’Agostino has written sections 4, 5.2 and 5.4; L. Neri has written Sects. 1, 3, 5.3.2 and 6.

钒－4－（2－噻唑偶氮）－间苯二酚的络合吸附波研究

运用单扫描示波极谱法，在ｐＨ５．５的乙酸－乙酸钠介质中找到了钒（Ｖ）－４－（２－噻唑偶氮－）间苯二酚（ＴＡＲ）络合物灵敏的吸附波，发现Ｖ（Ｖ）的浓度在２×ｌ０－３～４×ｌ０－６ｍｏｌ·Ｌ－１范围内与波峰高成线性关系；此吸附波为不可逆的络合吸附波；Ｖ（Ｖ）－ＴＡＲ络合比为１：１．运用该法测定矿石中的微量钒，得到了满意结果。

Sensitivity Analysis for Importance Assessment

We review briefly some examples that would support an extended role for quantitative sensitivity analysis in the context of model-based analysis (Section 1). We then review what features a quantitative sensitivity analysis needs to have to play such a role (Section 2). The methods that meet these requirements are described in Section 3; an example is provided in Section 4. Some pointers to further research are set out in Section 5.     

加强P除环上半正定（正定）自共轭矩阵乘积的特征值

得到了下述结果：１）加强Ｐ除环上两个ｎ阶半正定自共轭矩阵之积在Ｒ中至少有ｎ个形如‖ａ‖~２的特征值；特别地，当它们可换时，其积仍为半正定自共轭矩阵；２）加强Ｐ除环上两个ｎ阶正定自共轭矩阵之积在Ｒ中至少有ｎ个形如‖ａ‖~２（‖ａ‖≠０）的特征值；特别地，当它们可换时，其积仍为正定自共轭矩阵。
