Concept and career-stage differentiation in obsolescence research
基于544名以色列高科技专业人士的调查，研究了过时概念的区分、更新相关认知的区分以及职业阶段差异，发现对过时威胁的反应表现为收缩，且管理路径比技术路径更有利于更新。
The study aimed to further the differentiation in obsolescence research in three directions: differentiation of obsolescence concepts, differentiation of updating-related cognitions, and career-stage differentiation. Survey data from 544 professionals employed by high-tech organizations in Israel were collected. The analyses of differentiation in obsolescence and its related cognitions showed that the response to the obsolescence threat was characterized by constriction. Constriction was manifested in higher levels of updatedness in the closer scope, in the shorter time span, and in comparison to the more immediate reference groups. Other indications of constriction were the salience of the present job and the significant role played by the immediate supervisor in the updating pursuit. Two different meanings of updating could be distinguished—formal updating and incidental updating. The analyses of career differentiation identified stage differences in the extent of updating, obsolescence and organizational support of updating. They were mostly higher at more advanced stages. The managerial route was more advantageous to updating compared to the technical route. Finally, whereas the link of organizational support to updating behavior strengthened with career progress, its link to the obsolescence experience loosened. Implications of the findings are discussed.
