2 1 Introduction The use of panel data with interactive fixed effects in regression analyses has attracted considerable attention in the empirical literature in economics and elsewhere. One of the most common approaches to such models by far is the principal component (PC) approach of Bai (2009)...
College Station, TX: StataCorp LP). The trial was open-label and unmasked as the intervention required overt participation. The trial was however assessor-blinded to laboratory staff that analysed the EID HIV tests and to the authors of the paper. The randomisation code was disclosed to the ...
Because the PVAR model covers both time and fixed effects, the intra-group mean difference method is used to remove the time effect, and the indicators in the above formula (16) are turned into the average of the regional variables:(17)X¯i,t=βX¯i,t-1+δ¯i+ηt+ε¯i,t ...
Among the con- trol variables, economic Development Level (GDPpc), the logarithm of gross fixed assets investment (lnFAI), NTL, and P_built exhibit particularly pronounced differences across different groups. This study provides a robust understanding of the heterogeneous and interactive effects of ...

“bad” dimensions such as ethnoculturalism, a more exclusionary that defines American identity more narrowly in terms of race, ethnicity, and fixed cultural traits. Likewise, race is viewed as having an independent effect on immigration policy preferences, with being white shown to have a negative...
In the multidimensional framework that has emerged from this literature there is a clear argument that the dimensions of identity are interactive, even though much of the empirical work has focused on models that test only independent effects of national identity and of race. This literature has ...
Maximum Von Mises stress is located at the fixed end of the torsion spring. This stress is also caused with the stress concentration. Maximum working stresses occur in a different location of a spring wire due to complex stress conditions, i.e., the simultaneous effect of the bending moment ...
