Advancing Theory with Review Articles

Reviewing a body of work presents unique opportunities for making a theoretical contribution. Review articles can make readers think theoretically differently about a given field or phenomenon. Yet, review articles that advance theory have been historically under-represented in Journal of Management Studies. Accordingly, the purpose of this editorial is to propose a multi-faceted approach for fashioning theoretical contributions in review articles, which we hope will inspire more authors to develop and submit innovative, original, and high-quality theory-building review articles. We argue that advancing theory with review articles requires an integrative and generative approach. We propose a non-exhaustive set of avenues for developing theory with a review article: exposing emerging perspectives, analysing assumptions, clarifying constructs, establishing boundary conditions, testing new theory, theorizing with systems theory, and theorizing with mechanisms. As a journal, Journal of Management Studies is a journal of ideas – new ideas; ideas drawn from reflections on extant theory and ideas with potential to change the way we understand and interpret theory. With this in mind, we think that advancing theory with review articles is an untapped source of new ideas.     

The Information Content of Segment Disclosures: Australian Evidence

This paper investigates whether the voluntary decomposition of consolidated earnings disclosures into industry segments has information content in the sense that such disclosures better enable investors to predict earnings. The broad rationale underlying the experimental design is that if segment disclosure does enable investors to better predict earnings then residual abnormal returns (after controlling for unexpected earnings) surrounding the earnings announcements of firms providing segment disclosures should on average be significantly lower than a matched' group of firms that do not provide this type of disclosure. Using a short event window design, our results support this view.

Perceptions of predictive testing for those at risk of developing a chronic inflammatory disease: a meta-synthesis of qualitative studies*

Background: The availability of tests to predict the risk of developing chronic diseases is increasing. The identification of individuals at high risk of disease can trigger early intervention to reduce the risk of disease and its severity. In order for predictive tests to be accepted and used by those at risk, there is a need to understand people’s perceptions of predictive testing. Method: A meta-synthesis of qualitative research that explored patient and public perceptions of predictive testing for chronic inflammatory diseases was conducted. Studies were coded by researchers and patient research partners, and then organised into common themes associated with the acceptability or use of predictive testing. Results: Perceived barriers to predictive testing were identified, including a concern about a lack of confidentiality around the use of risk information; a lack of motivation for change; poor communication of information; and a possible impact on emotional well-being. In order to reduce these barriers, the literature shows that a patient-centred approach is required at each stage of the testing process. This includes the consideration of individual needs, such as accessibility and building motivation for change; readily available and easy to understand pre and post-test information; support for patients on how to deal with the implications of their results; and the development of condition specific lifestyle intervention programmes to facilitate sustainable lifestyle changes. Conclusion: Patients and members of the public had some concerns about predictive testing; however, a number of strategies to reduce barriers and increase acceptability are available. Further research is required to inform the development of a resource that supports the individual to make an informed decision about whether to engage in a predictive test, what test results mean, and how to access post-test support.     

基于层次分析法与变权理论的桥梁状态评估

层次分析法（AHP）将一个复杂问题分解为有序的阶递层次结构,并将定性因素定量化,在一定程度上减少了主观的影响,使评估更趋科学化。变权综合法比常权综合法更能反映出对于个别构件状态变化对总体评估结果的影响。文中将层次分析法和变权综合理论相结合建立了桥梁状态评估系统,提高了评估的质量。

The wage–employment relationship in Modigliani's 1944 article

Modigliani's 1944 “Econometrica” article is considered one of the most important efforts to reconcile Keynes with classical economic thinking through the wage rigidity hypothesis. The paper reconstructs the genesis of Modigliani's article and compares Modigliani's and Patinkin's interpretation of the wage–employment relationship. It also discusses Modigliani's contribution to the neoclassical synthesis, arguing that Modigliani's attention to the monetary origin of and solution to unemployment contrasts with the neoclassical synthesis neglecting of the monetary side of the system and its inclination towards fiscal policy.     

市场化改革后国有企业创造就业机会的途径研究

本文通过计算1999-2004年国有企业的综合就业系数和就业扩张比。证明国有企业的减员增效和战略性调整，虽降低了国有企业直接创造就业机会的能力，但间接创造就业机会的能力增强了，总的效果是国有企业创造就业机会的能力不降反升。因此在现代市场经济条件下，国有企业创造就业机会的途径，由原来的仅仅通过增加本企业的就业，转变为通过投入产出联系带动相关产业中其他企业的就业。这样。国有企业就可以通过不增加冗员的方式，承担创造就业机会的社会职能。
