Human Capital and Interethnic Marriage Decisions

Despite a longstanding belief that education importantly affects the process of immigrant assimilation, little is known about the relative importance of different mechanisms linking these two processes. This paper explores this issue through an examination of the effects of human capital on one dimension of assimilation, immigrant intermarriage. I argue that there are three primary mechanisms through which human capital affects the probability of intermarriage. First, human capital may make immigrants better able to adapt to the native culture thereby making it easier to share a household with a native. Second, it may raise the likelihood that immigrants leave ethnic enclaves, thereby decreasing the opportunity to meet potential spouses of the same ethnicity. Finally, assortative matching on education in the marriage market suggests that immigrants may be willing to trade similarities in ethnicity for similarities in education when evaluating potential spouses. Using a simple spouse-search model, I first derive an identification strategy for differentiating the cultural adaptability effect from the assortative matching effect, and then I obtain empirical estimates of their relative importance while controlling for the enclave effect. Using U.S. Census data, I find that assortative matching on education is the most important avenue through which human capital affects the probability of intermarriage. Further support for the model is provided by deriving and testing some of its additional implications.

Mercury in the Ocean

Making seafood choices isn't easy for consumers who want to minimize exposure to mercury but also take advantage of healthy Omega-3 fatty acids. Rob Mason's research on mercury in various ocean fish and shellfish, and his discussion of what factors are important to consider, helps readers make wise choices.

What Happens in the Links? Framing Judgment in Context

Scholars of Chaucer’s Canterbury Tales have focused much of their research on the interpretation of individual tales in the collection. The meaning behind these tales is clearly important to the work as a whole, as the Tales discuss grand themes that run throughout human life. The choice of themes and arguments in each pilgrim’s tale can also reflect back on the pilgrim’s own motivations and ideas. However, in searching for some greater meaning for Chaucer’s collection, it is important not to leave out the framework within which the tales exist. The links that join the tales to one another, arguably the portions of the piece that are the most original to Chaucer, do not always receive the same kind of attention that is focused on the most popular tales. In a work that is so complex, with its layered narration and interactions between tale and teller, the tales cannot possibly stand on their own, containing all of the meaning behind the work. The links have the potential to be particularly revealing in terms of how the audience should read the entire story of Chaucer’s Canterbury pilgrimage, because they ground the tales in specific circumstances.

Guessing Solutions to the H-atom Schrodinger Equation

In teaching elementary quantum chemistry, the concept of eigenfunctionality is explored using the H-atom's Hamiltonian and various guessed functions. This is done in Cartesian coordinates, in Spherical Polar coordinates, and in Confocal Elliptical coordinates.
