Extensions of Language Families and Canonical Forms for Full AFL-Structures

We consider the following ways of extending a family of languages $K$ to an "enriched" family $X(K)$: (i) hyper-algebraic extension ($X = H$) based on iterated parallel substitution, (ii) algebraic extension ($X = A$) obtained by nested iterated substitution, (iii) rational extension ($X = R$) achieved by not-self-embedding nested iterated substitution, and (iv) a few subrational extensions ($X = M, S, P, F, C$) based on several kinds of substitution. We introduce full $X$-AFL's, i.e. nontrivial families closed under finite substitution, intersection with regular sets and under $X$, which turn out to be equivalent to well-known AFL-structures such as full hyper-AFL ($X = H$), super-AFL ($A$), substitution-closed AFL ($R$), semi-AFL ($S$), etc. Then we establish Canonical Forms for the smallest full $X$-AFL $\hat{\cal X}(K)$ containing $K$, i.e. we decompose the operator $\hat{\cal X}$ into simpler operators. Using Canonical Forms for full $X$-AFL's we obtain expressions for the smallest full $X$-AFL containing the result of substituting a family of languages into another family

The racial practices of organized labor in the building and construction trades: a contemporary record, 1974

The primary intent of this thesis is to set forth descriptively and analytically, the racial practices of organized labor in the building and construction trades. Primary emphasis will be placed on the skilled segment of this trade, i.e., electricians, plumbers, sheet metal workers and pipe fitters, rather than the trowel trades which includes latherers, brick mason, etc. In the construction industry, trade unions racial practices are the decisive factor in determining the status of Black workers. The basic operational characteristic of craft union in the building trade is that they control access to employment by virtue of their rigid control of the hiring process. In this industry labor unions control the assignment of union members to jobs. The refusal to admit Blacks into membership denies Black workers the opportunity to secure employment. The materials for this study came mainly from civil rights and union organization records and interviews and newspapers. Also, a wide variety of secondary information, books, and periodicals were used

Socialism and nationalism in Australia and the United States, 1890-1914

En la década de 1890, EE.UU. acababa de cerrar oficialmente su frontera y estaba a las puertas de ser un Imperio, redefiniendo su mitología e identidad nacional en medio de un acelerado desarrollo industrial. En esa década, las Colonias Australianas estaban en pleno proceso de separación de Gran Bretaña y construcción nacional. En ambos casos las ideas papelistas y el radicalismo agrario representaban un nacionalismo radical. Este triunfó en EE.UU. por la derrota del populismo. Desde entonces socialismo y radicalismo se han considerado antiamericanos; mientras que en Australia el laborismo identificaba socialismo y construcción nacional
