Men's psychological functioning in the context of women's breast cancer

Previous research indicates that men are affected when their female partners have breast cancer. However, little is known about what predicts men's psychological well-being in this context. The current investigation involved couples in which the woman had early stage breast cancer and explored the degree to which men's positive and negative well-being was related to women's well-being, women's physical symptoms, relationship functioning, and relationship duration. The findings indicate that all of these factors play a role and interact in predicting men's well-being. In particular, when women have a high level of physical symptoms, the typical associations between men's well-being with women's well-being and relationship adjustment no longer persist. Implications for working with couples addressing health problems are provided.     

Negative Dependence in Sampling

Abstract. The strong Rayleigh property is a new and robust negative dependence property that implies negative association; in fact it implies conditional negative association closed under external fields (CNA+). Suppose that and are two families of 0‐1 random variables that satisfy the strong Rayleigh property and let . We show that {Z_i} conditioned on is also strongly Rayleigh; this turns out to be an easy consequence of the results on preservation of stability of polynomials of Borcea & Brändén (Invent. Math., 177, 2009, 521–569). This entails that a number of important π ps sampling algorithms, including Sampford sampling and Pareto sampling, are CNA+. As a consequence, statistics based on such samples automatically satisfy a version of the Central Limit Theorem for triangular arrays.
