Abstract
Purpose
The aim of this paper is to extend the understanding of the configuration of inter-organizational information exchange (IOIE) and the role of each aspect of IOIE in realizing potential communication benefits.
Design/methodology/approach
A conceptual framework on the configuration of IOIE was developed by examining the relationships between companies in the poultry supply chain in China. A sample of 165 buying companies and a sample of 96 sellers were analyzed by partial least square modeling.
Findings
Communication willingness plays a critical role in improving communication quality and realizing potential communication benefits. Modern media remain as a huge potential opportunity for improving performance. Meanwhile, the power of face-to-face communication should never be neglected, even in the coming Information Age. Higher communication frequency contributes to better understanding of companies' changing requirements and expectations. Taking use of senior managers and staff from different functions helps sellers grasp better changing markets. Communication quality is found as a multi-dimensional concept and plays a critical mediating role in realizing communication benefits.
Originality/value
The proposition of the model of configuration of inter-organizational information exchange and the quantitative empirical examination of the model fills an important research gap.

Abstract
Purpose
Hydraulic instabilities are one of the most important reasons causing vibrations and fatigues in hydraulic turbines. The present paper aims to find the relationship between pressure pulsations and fatigues of key parts of a Kaplan turbine.
Design/methodology/approach
3D unsteady numerical simulations were preformed for a number of operating conditions at high heads for a prototype Kaplan turbine, with the numerical results verified by online monitoring data. The contact method and the weak fluid‐structure interaction method were used to calculate the stresses in the multi‐body mechanism of the Kaplan turbine runner body based on the unsteady flow simulation result.
Findings
The results show that vortices in the vaneless space between the guide vanes and blades cause large pressure pulsations and vibrations for high heads with small guide vane openings. The dynamic stresses in the runner body parts are small for high heads with large guide vane openings, but are large for high heads with small guide vane openings.
Originality/value
A comprehensive numerical method including computational fluid dynamics analyses, finite element analyses and the contact method for multi‐body dynamics has been used to identity the sources of unit vibrations and key part failures.

Abstract
Purpose
The present paper constructed a new framework for government data governance based on the concept of a data middle platform to elicit the detailed requirements and functionalities of a government data governance framework.
Design/methodology/approach
Following a three-cycle activity, the design science research (DSR) paradigm was used to develop design propositions. The design propositions are obtained based on a systematic literature review of government data governance and data governance frameworks. Cases and experts further assessed the effectiveness of the implementation of the artifacts.
Findings
The study developed an effective framework for government data governance that supported the digital service needs of the government. The results demonstrated the advantages of the framework in adapting to organizational operations and data, realized the value of data assets, improved data auditing and oversight and facilitated communication. From the collection of data to the output of government services, the framework adapted to the new characteristics of digital government.
Originality/value
Knowledge of the “data middle platforms” generated in this study provides new knowledge to the design of government data governance frameworks and helps translate design propositions into concrete capabilities. By reviewing earlier literature, the article identified the core needs and challenges of government data governance to help practitioners approach government data governance in a structured manner.
