Roads and roadblocks to dual commitment: Similar and dissimilar antecedents of union and company commitment

Dual commitment received wide attention during the 1950s and, after a waning of interest during the 1960s and 1970s, interest has grown anew. In this study of dual commitment we used a model of investment and returns, applied referent theory to it, and grounded the investigation in an industrial relations context at an airline carrier in order to examine both company and union commitment. We found that wages were a positive income elastic good with respect to company commitment, but they were a negative good with respect to union commitment. Information obtained from the firm or the union also resulted in divergencies in the commitments. External labor market variables were unrelated to union commitment, but they were related to company commitment. Finally, job influence and perceptions concerning a labor-management program were positive predictors of the two commitments; as such, they have implications for the way firms and unions may want to build dual commitment.

Deinstitutionalization: a public policy perspective

1. Deinstitutionalization was initiated in an era of social reform to protect the rights of the mentally ill; however, a strong research base was absent and led to major flaws in the policy's implementation. 2. The chronically mentally ill are frequently poor advocates for themselves and, without even the most simple needs fulfilled, end up homeless. 3. The homeless mentally ill require comprehensive support systems with assured continuity of care. An emerging concept to deal with this issue is that of case management. 4. The mental health professional can strive to influence future public policy as patient advocate and nonpartisan educator.     

Siblings of handicapped children

There is a strong suggestion that the siblings of handicapped children are at risk psychologically. Factors which contribute to this risk, aspects of the sibling relationship, and the siblings' issues, concerns and feelings are discussed so that professionals may have a framework within which to assess and evaluate these children's needs. Case examples are given.     

Strategy-proofness on Euclidean spaces

 In this paper we characterize strategy-proof voting schemes on Euclidean spaces. A voting scheme is strategy-proof whenever it is optimal for every agent to report his best alternative. Here the individual preferences underlying these best choices are separable and quadratic. It turns out that a voting scheme is strategy-proof if and only if (α) its range is a closed Cartesian subset of Euclidean space, (β) the outcomes are at a minimal distance to the outcome under a specific coordinatewise veto voting scheme, and (γ) it satisfies some monotonicity properties. Neither continuity nor decomposability is implied by strategy-proofness, but these are satisfied if we additionally impose Pareto-optimality or unanimity.
