請依下文回答第 46 題至第 48 題：Who really makes the changes in an organization? It’s not always the people with the highest executive titles. Agrowing body of research has pointed to the importance of informal leaders known as “brokers,” who have the gift ofconnecting employees in productive new ways. New research by Professor Brands has uncovered bias surroundingbrokerage roles. Professor Brands examined what are known as “friendship networks” within organizations. In this sense,friends are the people you turn to for help, advice, and information, whether or not they are in your work group. Simplyput, you like and trust them. It’s within these friendship networks that much of an organization’s work gets done.In a study of two separate groups–employees of an electronic-components distributor and a cohort of M.B.A.students–she identified brokers based on the high level of connectivity they displayed. They also identified the peoplewho were perceived by their colleagues to be brokers. Researchers asked members to evaluate their colleagues, includingthe actual and perceived brokers. This is where gender differences emerged. The researchers found that people tended toignore the activities of female brokers and to exaggerate how much men served as brokers. If women were recognized asbrokers, they were perceived more negatively. “They incurred reputation penalties,” Professor Brands says. “They wereseen as more competent, but less warm.” Other research, she says, has shown that men who take on brokerage roles tendto receive benefits in the form of compensation and promotions, whereas female brokers’ careers are negatively affected.Professor Brands also analyzed the performance of the brokers’ teams. They found that women who were thought by theirteams to be brokers tended to perform well individually, but at the expense of their overall team’s performance. Theprofessors noted that men are traditionally defined by words like aggressive, forceful, independent, and decisive. Womenare expected to be kind, helpful, sympathetic, and concerned about others. Women are thought to excel in the socialrealm–so you would think that they would be seen as good work brokers, the researchers said. But “despite thewidespread notion of women as social specialists, perceptions of the network position of women will be distorted becauseof the expectation that brokerage is man’s work,” they wrote.
