This study examined differences in kin and nonkin networks among African Americans, Caribbean Blacks (Black Caribbeans), and nonHispanic Whites. Data are taken from the National Survey of American Life, a nationally representative study of African Americans, Black Caribbeans, and non-Hispanic Whites. Selected measures of informal support from family, friendship, fictive kin, and congregation/ c...

Research indicates that friendship contributes to wellbeing in later life in various ways: through the provision of companionship in daily life, support during stressful transitions, sustainment of identity under changing circumstances and adaptation to old age. However not all older people have friends available who fulfil these different functions. In order to promote wellbeing and reduce lon...

We examined the cognitive processes that might account for the impact of cross-group friendship on novel intergroup situations. Study 1 demonstrated that closeness with outgroup members predicts an association of the outgroup with the self, both in terms of the group itself and the personality traits stereotypically associated with the group. In Studies 2 and 3, we manipulated the accessibility...

A graph G is H-saturated if G does not contain H as a subgraph but for any nonadjacent vertices u and v, G+uv containsH as a subgraph. The parameter sat(H, n) is theminimum number of edges in an H-saturated graph of order n. In this paper, we determine sat(H, n) for sufficiently large nwhen H is a union of cliques of the same order, an arbitrary union of two cliques and a generalized friendship...

An important subclass of social choice functions, so-called majoritarian (or C1) functions, only take into account the pairwise majority relation between alternatives. In the absence of majority ties—e.g., when there is an odd number of agents with linear preferences—the majority relation is antisymmetric and complete and can thus conveniently be represented by a tournament. Tournaments have a ...

The Friendship theorem states that if any two people in a party have exactly one common friend, then there exists a politician who is a friend of everybody. In this paper, we generalize the Friendship Theorem. Let λ be any nonnegative integer and μ be any positive integer. Suppose each pair of friends have exactly λ common friends and each pair of strangers have exactly μ common friends in a pa...

In this note, we consider the i-block intersection graphs (i-BIG) of a universal-friend friendship 3-hypergraph and show that they are pancyclic for i = 1, 2. We also show that the 1-BIG of a universalfriend friendship 3-hypergraph is Hamiltonian-connected.

This multi-study investigation identified and confirmed the factor structure of ideal friendship standards. Study 1 (N = 307) conducted an exploratory factor analysis on 30 existing subscales of friendship expectations. Study 2 (N = 401) reduced 181 items from past subscales and singleitem measures of friendship expectations to 51 items measuring six factors. Study 3 (N = 668) used an internati...
