The dependence of the overlayer growth on the underlying substrate is illustrated in this study of MgCl{sub 2} thin films on the following substrates: Pd(111), Pt(111), Pd(100) and Rh(111). On Pd(111) and Pt(111), the TPD of the deposited MgCl{sub 2} showed a significant substrate-adsorbate interaction as evidenced by a monolayer desorption feature. The interaction was further attested by the formation of two monolayers LEED patterns -- Pd(111)-(4x4)-MgCl{sub 2} and Pd(111)-({radical}13 x {radical}13)-R 13.9{degrees}-MgCl{sub 2}. Also, on Pd(111) and Pt(111), a multilayer coverage pattern was grown, MgCl{sub 2} (1 x 1). When Pd(100) was used as the substrate, the monolayer desorption feature disappeared from the TPD as well as the two monolayer patterns seen on Pd(111), but a MgCl{sub 2} (1 x 1) pattern with multiple rotated domains was created as the multilayer coverage. This difference resulted from the fact that the Pd(100) does not possess the correct angle for the (0001) face of the MgCl{sub 2}. To preserve this angle, the deposition of MgCl{sub 2} was performed on Rh(111) and the reconstructed face of Pt(100). Again, evidence of the strong substrate-adsorbate interaction was gone. The buckling of Pt(100)`s surface layer caused this result. For the Rh(111), the lattice match wasmore » not preserved with the angle.« less

The common understanding of Karl Marx attributes to him a theory of radical polarization and simplification of the class structure, where the maturation of capitalism eventually results in the mechanical subsumption of all intermediate groupings into a growing and increasingly homogeneous and militant working class. A number of common themes emerge in the Weberian treatments of the middle class, in addition to the ones directly or indirectly derived from Weber. Hindsight makes it quite obvious that theories of the middle classes are both responses to preexisting sociopolitical perceptions of these groups and attempts to influence these perceptions. Bourgeois managers can dissimulate the permanence of their rule by confounding themselves into its "middle mass," and foremen reap the symbolic profits attached to being identified with superior occupations. The large body of writings devoted to the middle classes and the executive that flourished in the 1930s, particularly after 1936, borrowed much of its materials from corporatist ideology, social Catholicism, and Italian fascism.
