Older adults' perceptions of work

Traditional definitions of work may not reflect the activities of older adults. A broader definition that incorporates non-economic as well as economic measures may better describe their participation in the labor force and the meanings they ascribe to these activities. Because productive activity has been linked to successful aging, it is important to understand how elders perceive work. Twenty-six community-residing older adults were interviewed over a two-year period. Participants were mostly female and represented diverse cultural, religious and educational backgrounds. All these individuals participated in some activities they perceived as work. Three themes emerged as describing their attributions of meaning or importance to productive activities: contribution to self-concept, giving back to community, and staying engaged. Findings suggest that the productive activities of older adults contribute to quality of life for them and have implications for society as well.     

Personal meanings of occupation for women in later life: two women compared

Understanding the meaning of occupation for older women presents challenges to care providers because of the highly individual manner in which they enact those meanings. Two women interviewed in depth over a two-year period demonstrate the unique characteristics of activity patterns of older women, the meanings they ascribe to them, and the contribution of those activities to quality of life. The women were demographically similar, and described engaging in several common activity categories (connection to others, doing good, spiritual expression) that were particularly meaningful to them. The specific activities that they undertook were quite different. Findings suggest the importance of obtaining detailed information about older women in making plans for intervention to support desired activities in later life.     

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.
