The Transmission of Women's Fertility, Human Capital and Work Orientation across Immigrant Generations

Using 1995–2006 Current Population Survey and 1970–2000 Census data, we study the intergenerational transmission of fertility, human capital and work orientation of immigrants to their US-born children. We find that second-generation women's fertility and labor supply are significantly positively affected by the immigrant generation's fertility and labor supply respectively, with the effect of mother's fertility and labor supply larger than that of women from the father's source country. The second generation's education levels are also significantly positively affected by that of their parents, with a stronger effect of father's than mother's education. Second-generation women's schooling levels are negatively affected by immigrant fertility, suggesting a quality-quantity tradeoff for immigrant families. We find higher transmission rates for immigrant fertility to the second generation than we do for labor supply or education: after one generation, 40-65% of any immigrant excess fertility will remain, but only 12-18% of any immigrant annual hours shortfall and 18-36% of any immigrant educational shortfall. These results suggest a considerable amount of assimilation across generations toward native levels of schooling and labor supply, although fertility effects show more persistence.immigration, second generation, gender, labor supply, fertility, human capital

Formal vs self-organised knowledge systems: a network approach

In this work we consider the topological analysis of symbolic formal systems in the framework of network theory. In particular we analyse the network extracted by Principia Mathematica of B. Russell and A.N. Whitehead, where the vertices are the statements and two statements are connected with a directed link if one statement is used to demonstrate the other one. We compare the obtained network with other directed acyclic graphs, such as a scientific citation network and a stochastic model. We also introduce a novel topological ordering for directed acyclic graphs and we discuss its properties in respect to the classical one. The main result is the observation that formal systems of knowledge topologically behave similarly to self-organised systems.Comment: research pape

On the behaviour of Brauer pp-dimensions under finitely-generated field extensions

The present paper shows that if $q \in \mathbb P$ or $q = 0$, where $\mathbb P$ is the set of prime numbers, then there exist characteristic $q$ fields $E _{q,k}\colon \ k \in \mathbb N$, of Brauer dimension Brd$(E _{q,k}) = k$ and infinite absolute Brauer $p$-dimensions abrd$_{p}(E _{q,k})$, for all $p \in \mathbb P$ not dividing $q ^{2} - q$. This ensures that Brd$_{p}(F _{q,k}) = \infty$, $p \dagger q ^{2} - q$, for every finitely-generated transcendental extension $F _{q,k}/E _{q,k}$. We also prove that each sequence $a _{p}, b _{p}$, $p \in \mathbb P$, satisfying the conditions $a _{2} = b _{2}$ and $0 \le b _{p} \le a _{p} \le \infty$, equals the sequence abrd$_{p}(E), {\rm Brd}_{p}(E)$, $p \in \mathbb P$, for a field $E$ of characteristic zero.Comment: LaTeX, 14 pages: published in Journal of Algebra {\bf 428} (2015), 190-204; the abstract in the Metadata updated to fit the one of the pape
