BEYOND DIRECT AND SYMMETRICAL EFFECTS: THE INFLUENCE OF DEMOGRAPHIC DISSIMILARITY ON ORGANIZATIONAL CITIZENSHIP BEHAVIOR.
研究员工与同事在人口学特征（如种族、年龄）上的差异如何通过信任、自尊等心理机制影响其组织公民行为，且这种影响因员工自身特征和团队构成而异。
It is argued that employees' attraction to and trust in their peers, and their organization-based self-esteem mediate the effect of demographic dissimilarity on organizational citizenship behavior (OCB). Data from a held study support a model in which the relationship between demographic dissimilarity and OCB is contingent on demographic characteristics and work group composition and mediated to an extent by the proposed mediators. The influence of race dissimilarity varied in strength for white and minority employees, but the influence of age dissimilarity varied in direction for older and younger employees.
