Evidence from developed and developing countries alike demonstrates a strongly positive relationship between religiosity and happiness, particularly for women and particularly among the elderly. Using survey data from the oldest old in China, we find a strong negative relationship between religious participation and subjective well-being in a rich multivariate logistic framework that controls for demographics, health and disabilities, living arrangements and marital status, wealth and income, lifestyle and social networks, and location. In contrast to other studies, we also find that religion has a larger effect on subjective well-being on men than women.

Calixarenesare macrocycles composed of benzene rings meta linked to each other by one carbon atom. These exotic compounds can be used for a variety of purposes including metalleaching for environmental cleanup, surface technology, luminescent probes, nuclear waste treatment, among others. A variety of calixarenesexist, including azacalix[n]arenesthiocalix[n]arenes(where n = the number of benzene rings) and oxacalix[n]arenes; these macrocycles use nitrogen, sulfur and oxygen, respectively, as the atom whichlinks the benzene rings together. My research has focused on synthesizing oxacalix[6]arenes (“hexamer”) in high yield, which is a synthetic challenge because it is generally accepted that oxacalix[n>4]arenes will thermodynamically decompose to the oxacalix[4]arene (“tetramer”); i.e. heating the reaction mixture will yield the tetramer, not the hexamer. To generate the hexamer, “trimer”precursors have been synthesized, in the hopes of facilitating hexamer ring closure.
