The advancement of enterprise social networks (ESNs) facilitates information sharing but also presents the challenge of managing information boundaries. This study aims to explore the factors that influence the information-control behavior of ESN users when continuously sharing information.

This study specifies the information-control behaviors in the “wall posts” channel and applies communication privacy management (CPM) theory to analyze the effects of the individual-specific factor (disposition to value information), context-specific factors (work-relatedness and information richness) and risk-benefit ratio (public benefit and public risk). Data on actual information-control behaviors extracted from ESN logs are examined using multilevel mixed-effects logistic regression analysis.

The study's findings show the direct effects of the individual-specific factor, context-specific factors and risk-benefit ratio, highlighting interactions between the individual motivation factor and ESN context factors.

This study reshapes the relationship of CPM theory boundary rules in the ESN context, extending information-control research and providing insights into ESNs' information-control practices.

The use of social networking sites (SNSs) can promote life satisfaction mainly because of their social relationship benefits. Although prior studies examined the roles of different types of social capital (SC), the association between online and offline SC is ignored. This research addresses this gap by uncovering a mechanism of transformation between online and offline SC in terms of bonding and bridging types when linking SNSs usage and life satisfaction.

Categorizing the concept of SC into four sub-types from bonding/bridging and online/offline dimensions, the paper establishes a theoretical framework based on the transformation mechanism among these four kinds of SC. A component-based approach, partial least square method, is chosen for hypothesis testing with a survey-based sample collected from WeChat users.

First, SNSs usage is positively related to life satisfaction and four types of SC (i.e. online/offline and bonding/bridging SC). Second, both online bonding SC and offline bridging SC are positively related to life satisfaction and can mediate the relationship between SNSs usage and life satisfaction. Third, offline bonding SC is positively related to online bonding SC and can mediate the relationship between SNSs usage and online bonding SC; on the contrary, online bridging SC is positively related to offline bridging SC and can mediate the relationship between SNSs usage and offline bridging SC.

In the environment of SNSs, users can take vigorous strategies to better balance online and offline spaces and improve life satisfaction by adapting to the characteristics of SNSs in developing different types of SC. Specifically, it is encouraged for users to transfer online bridging SC into offline space and offline bonding SC into online space.

To the best of the authors’ knowledge, this is the first study exploring the association between online and offline SC when linking SNSs usage and life satisfaction. Instead of the single transformation direction from online to offline in prior Internet research, this research has revealed different transformation directions between online and offline SC in terms of bonding and bridging types in the context of SNSs.

Social networking services (SNSs) have been praised for their social capital (SC) benefits. However, the time displacement hypothesis in Internet research may challenge such an optimistic view. In response to this challenge, this study aimed to develop a theoretical model that uncovers the transformation, rather than displacement among online and offline SC in terms of bonding and bridging types during SNSs use.

The concept of SC was divided into the following four types: offline bonding, online bonding, offline bridging and online bridging. A theoretical model grounded in individual ambidexterity theory was developed that uncovered the transformation among these types of SC, and it was tested a sample of WeChat users in China. Furthermore, the theoretical model included the concept of cognitive ambidexterity, which promotes transformation.

As an exploitation process, offline bonding SC mediated the relationship between SNSs use and online bonding SC. As an exploration process, online bridging SC mediated the association between SNSs use and offline bridging SC. In addition, cognitive ambidexterity moderated the exploration and exploitation processes positively.

This study demonstrated that SNSs users strategically and successfully manage SC benefits through exploitation and exploration processes, and ambidextrous individuals can do this more effectively. Accordingly, this study proposed the transformation hypothesis in the SNSs context.

The purpose of this paper is to explore how to use social media in e-government to strengthen interactivity between government and the general public.

Categorizing the determinants to interactivity covering depth and breadth into two aspects that are the structural features and the content features, this study employs general linear model and ANOVA method to analyse 14,910 posts belonged to the top list of the 96 most popular government accounts of Sina, one of the largest social media platforms in China.

The main findings of the research are that both variables of the ratio of multimedia elements, and the ratio of external links have positive effects on the breadth of interactivity, while the ratio of multimedia features, and the ratio of originality have significant effects on the depth of interactivity.

The contributions are as follows. First, the authors analyse the properties and the topics of government posts to draw a rich picture of how local governments use the micro-blog as a communications channel to interact with the public. Second, the authors conceptualize the government online interactivity in terms of the breadth and depth. Third, the authors identify factors that will enhance the interactivity from two aspects: structural features and content features. Lastly, the authors offer suggestions to local governments on how to strengthen the e-government interactivity in social media.

This study aims to answer few questions, such as which factors influence the local government’s choice of private firm investments; what factors influence private firms’ choice of specific local government to make a local investment; and why do some private firms gain a competitive edge by choosing a stakeholder management model of “running the government” in the context of the Chinese transition economy.

Using a case study approach, this paper provides an in-depth analysis of the Daqing–Geely Case, 2010, and explains why Geely chose Daqing considering the firm perspective and why the Daqing city Government chose Geely considering the local governments’ perspective.

This study highlights the concept of “co-beneficial” cooperation between government–business by virtue of the institutional innovation of the quasi-property system. In addition, it reveals that the private firms and local governments in the “Daqing–Geely mode” work together for mutual benefits by putting fair negotiation and contract mechanisms in place. Resultantly, private firms secure the commercial interests, and the local governments bring in improved efficiency.

This study consolidates the theory of stakeholders, thereby strengthening the current understanding of “special offer” and “universal offer.”

This study aims to improve the tribological properties of hydrodynamic journal bearing via surface texture, as well as the wear and antifriction mechanisms of textured bearing were represented. It provides a design direction for solving the tribological problem of rotor-bearing system.

In this paper, the variation of surface texture parameters (e.g. texture diameter, d; area density, sp; and depth, hp) were analyzed based on finite difference method. The optimal surface texture parameters were obtained by designing orthogonal experiments, and the relationship between friction and wear properties and microstructure was studied via combining electron probe microanalyzer, scanning electron microscope, X-ray diffractometer and friction and wear testing machine.

Dimensionless film pressure P increased as the d increased, whereas P first increased and then decreased as the sp and hp increased, and the maximum P was got as sp = 15% and hp = 25 µm, respectively. The friction coefficient of textured surface with suitable parameters was effectively reduced and the textured surface with the best antifriction effect was 5#. Orthogonal experimental design analysis showed that the influence order of factors on friction coefficient was as follows: sp > sp × d > d > d × hp > hp > sp × hp and the friction coefficient first decreased and then increased as the sp, d and hp increased. In addition, the friction and wear mechanism of textured bearing were three body friction and abrasive wear as the matrix structure and hard phase were a single β phase and Mn5Si3, respectively. While the antifriction mechanism of textured surface was able to store abrasive particles and secondary hydrodynamic lubrication was formed.

The sample with reasonable texture parameter design can effectively reduce friction and wear of hydrodynamic journal bearing without reducing the service life, which can provide a reference for improving the lubrication performance and mechanical efficiency of rotor-bearing system.

The aim of this paper is to examine the evolution and development of the selection process and methods used by the Chinese government for appointing public officials.

The paper adopts an approach combining literature and document reviews with discussion with field experts.

China has a long history of selecting the most able individuals for government officials. During the political turmoil of the twentieth century, this was abandoned for ideological reasons. Current selection criteria and process are increasingly based on solid psychology and management approaches.

This paper is an overview of developments in Chinese government official selection approaches and process.

It may serve as a baseline for future research and practice on exploring sound and institutionalized selection methods and processes.

This is an initial attempt to explore senior Chinese officials' selection process.

The paper aims to identify and analyze passengers’ riding paths for providing better operational support for digital transformation in megacity metro systems.

The authors develop a method to leverage certain passengers’ deterministic riding paths to corroborate other passengers’ uncertain paths. Using Automatic Fare Collection data and train schedules, a witness model is built to recover the actual riding paths for passengers whose paths are unknown otherwise. The identification and analysis of passenger riding paths between three different types of origin–destination) pairs reveal the complexity of passenger path choice.

The results show that passenger path choice modeling is usually characterized by complexity, experience and partial blindness. Some passengers choose paths that are not optimal due to their experience and limited access to overall metro system information. These passengers could be the subject of improved path guidance in light of riding efficiency improved through digital transformation.

This research contributes to the improvement of metro management and operations by leveraging ongoing digital transformation in megacity metro systems. Based on the riding paths and trip chains of a large number of individual passengers identified by the proposed method, metro operation management could prevent risks in areas with concentrated passenger flow in advance, optimally adjust train schedules on a daily basis and deliver real-time riding guidance station by station, which would greatly improve megacity metro systems’ service safety, quality and operational efficacy over time.
