The dissemination of misleading and false information through media can jeopardize a company’s reputation, thus posing a threat to its stock and performance. Institutional investors are known to influence capital markets. Therefore, this paper investigates whether institutional investors engage in shaping the media sentiment stock nexus, stabilize company stocks and enhance performance.

We first investigate the effect of media sentiment on market reactions by using panel regression models. To examine the role of institutional investors, we design a quasi-experiment by exploiting the Financial Crisis of 2008 and go further by examining the heterogeneity across levels of institutional ownership. Due to risk-averse, investors may respond asymmetrically to pessimistic and positive sentiment. Accordingly, we split the sample into two sub-types, good news and bad news, based on keywords representing positive or negative content.

We find supportive evidence that institutional investors have impacts on how the markets react to media news, and the impacts are heterogeneous in the face of bad and good news. We conjecture that institutional investors act as a stabilizer of stock prices through media sentiment management.

This paper confirms the distinctive effects of institutional investors on capital markets, and uncovers the behind-the-scenes intervention and possible causal link running from institutional investors to media sentiment management. It contributes to the broad field of institutional investors' behavior, media news involvement in capital markets and market efficiency.

The National Bibliographic Information Network (NBINet) in Taiwan is a bibliographic database established on 30 October 1991 and maintained by the National Central Library. In 1998 there were 26 member libraries and 70 non‐member libraries in NBINet, which is considered a comprehensive database for Chinese studies worldwide and contains more than 1.6 million bibliographic records. This paper discusses the problems encountered in the establishment of NBINet and the solutions related to computers and networks, NBINet’s utilization on the Internet, and user expectations of NBINet.

Metadiscourse is an important dialogue technique used in productive knowledge building to help a group evaluate and advance their knowledge progress. Previous studies have identified and defined various types of metadiscourse. However, there is scant knowledge about how different metadiscourse types emerge among different groups or what implicit correlations lie between progressive discourse and metadiscourse. Moreover, research on how different types of metadiscourse influence groups' knowledge advancement and artifacts is still inadequate. Therefore, this study aims to further examine the roles that different types of metadiscourse play in the collaborative knowledge building community on both a fine-grained (i.e. progressive discourse) and coarse-grained (i.e. group knowledge advancement and group artifacts) level.

Data for this study are drawn from the behaviour of undergraduate students participating in a 12-week course at a key university in China. On the fine-grained level, epistemic network analysis (ENA) is applied to illustrate how metadiscourse promotes the development of progressive discourse. On the coarse-grained level, two different chi-square tests are conducted to examine the roles of different types of metadiscourse in groups' knowledge advancement and artifacts.

The analysis allowed several conclusions to be drawn. First, the types of metadiscourse that students most often adopted were reflecting on ideas development (RD) and commenting on ideas (CI); they less frequently adopted setting group goals (SG) and making group plans (MP). Second, most types of metadiscourse correlated with developments in progressive discourse, particularly RD and CI. Third, the metadiscourse types RD, CI and coordinating group efforts (CE) played essential roles in knowledge advancement. Fourth, higher-quality artifacts could be created by using the metadiscourse type reviewing the state of knowledge building progress (RP).

A more profound comprehension of the role that metadiscourse plays in the collaborative knowledge building community not only contributes to the literature in the knowledge building field but also carries a significant meaning in regulating community, promoting learner agency and sustained knowledge, and consequently improving collaborative learning performance.

This study addresses a central research question: Is individuals’ propensity to hide knowledge a “political phenomenon” among researchers in the Indian higher education institutions? Drawing upon social exchange and uncertainty management theories, the authors examine how a three-way interaction effect of perceptions of organizational politics, political will and political skill contributes to knowledge hiding. In addition, this study aims to develop a nuanced understanding of the knowledge hiding phenomenon in the Indian higher education context.

This study adopts a mixed-method study design with an explanatory sequential approach. The authors gathered data through a cross-sectional survey of 286 researchers (Study 1) followed by two focus group discussions (Study 2) involving 13 academic researchers from five Indian universities. The sample includes full-time faculty members, postgraduate and full-time doctoral students engaged in research.

The results of Study 1 indicate that researchers’ perceptions of organizational politics positively relate to their knowledge hiding. The findings of this study also suggest that the positive relationship between perceptions of organizational politics and knowledge hiding turns negative for individuals with high political will and high political skill. The focus group discussions (Study 2) explore significant predictors of knowledge hiding. This study unveils various characteristics of knowledge, knowledge hider, knowledge seeker and interpersonal dynamics as the key drivers of knowledge hiding in Indian academia.

The significant contributions of this study are to provide new insights into the relationship between organizational politics and knowledge hiding and to unravel the various factors that incite knowledge hiding among researchers in the Indian higher education context. This study is one among the few in the knowledge hiding literature to adopt a mixed-method research design with an explanatory sequential approach.
