Abstract

Purpose

First, the authors analyze the key problems faced by the protection of digital library readers' data privacy and behavior privacy. Second, the authors introduce the characteristics of all kinds of existing approaches to privacy protection and their application limitations in the protection of readers' data privacy and behavior privacy. Lastly, the authors compare the advantages and disadvantages of each kind of existing approaches in terms of security, efficiency, accuracy and practicality and analyze the challenges faced by the protection of digital library reader privacy.

Design/methodology/approach

In this paper, the authors review a number of research achievements relevant to privacy protection and analyze and evaluate the application limitations of them in the reader privacy protection of a digital library, consequently, establishing the constraints that an ideal approach to library reader privacy protection should meet, so as to provide references for the follow-up research of the problem.

Findings

As a result, the authors conclude that an ideal approach to reader privacy protection should be able to comprehensively improve the security of all kinds of readers' privacy information on the untrusted server-side as a whole, under the premise of not changing the architecture, efficiency, accuracy and practicality of a digital library system.

Originality/value

Along with the rapid development of new network technologies, such as cloud computing, the server-side of a digital library is becoming more and more untrustworthy, thereby, posing a serious threat to the privacy of library readers. In fact, the problem of reader privacy has become one of the important obstacles to the further development and application of digital libraries.

Abstract

Purpose

The purpose of this paper is to provide a conceptual model for examining the effects of trust (competence trust, goodwill trust) and cooperation on partner opportunism and for exploring the moderating effects of guanxi on the relationships among trust, cooperation and opportunism in joint ventures.

Design/methodology/approach

The sample for this paper comprises 981 manufacturing joint ventures from various industrial sectors. A total of 354 valid questionnaires were collected, representing a 36 per cent response rate. The conceptual model is tested with structural equation modeling adopting AMOS software.

Findings

The empirical findings indicate that both competence trust and goodwill trust reduce partner opportunism in a joint venture through fostering cooperation. Competence trust also exerts significant influence on preventing opportunism, whereas opportunistic behavior is not greatly affected by goodwill trust. Additionally, the results reveal that guanxi helps strengthen the negative relationship between cooperation and opportunism.

Originality value

This paper makes a threefold contribution: First, it investigates empirically the direct influence of two types of trust on partner opportunism. Second, it tests indirect influence of trust on partner opportunism through the path of cooperation. Third, it explores the moderating effects of guanxi in relationships on trust, cooperation and partner opportunism. Implications offers suggestions for management practice to reduce partner opportunism in joint-venture manufacturing.

Abstract

Purpose

Motivated by the need for research on the relationship between health app usage and health-related outcomes in the form of health status and life satisfaction, this study builds on self-regulation theory to construct a research model for elucidating how health app quality affects health information literacy, health app usage and physical activity.

Design/methodology/approach

To empirically validate the proposed research model, a large-scale questionnaire survey on health app usage was administered on a sample of 6,948 respondents recruited from a university in China. Structural equation modeling was employed for data analysis.

Findings

Empirical findings demonstrate that health app quality positively affects self-regulation with respect to health app usage, health information literacy and physical activity. Taken together, these self-regulated behaviors drive health-related outcomes for health status and life satisfaction.

Originality/value

This study advances extant literature on health app usage through the application of self-regulation theory to investigate the effects of technological interventions in healthcare. Findings offer practical implications for how health apps can be leveraged to realize positive health-related outcomes.

Abstract

Purpose

This study aims to examine the association between fair value accounting and the cost of corporate bonds, proxied by bond yield spread. In addition, this study explores the moderating role of auditor industry expertise at both the national and the city levels.

Design/methodology/approach

This study first examines the effect of the use of fair value on yield spread by estimating firm-level regression model, where fair value is the testing variable and yield spread is the dependent variable. To test the differential impact of the three levels of fair value inputs, this paper divides the fair value measures based on the three-level hierarchy, Level 1, Level 2 and Level 3, and replace them as the test variables in the regression model.

Findings

This study finds that the application of fair value accounting is generally associated with a higher bond yield spread, primarily driven by Level 3 estimates. The results also show that national-level auditor industry expertise is associated with lower bond yield spreads for Level 1 and Level 3 fair value inputs, whereas the impact of city-level auditor industry expertise on bondholders is mainly on Level 3 fair value inputs.

Research limitations/implications

The paper innovates by exploring the impact of fair value accounting in a setting that extends beyond financial institutions, the traditional area of focus. Moreover, most prior research considers private debt, whereas this study examines public bonds, for which investors are more likely to rely on financial reporting for their information about a firm. Finally, the study differentiates between city- and national-level industry expertise in examining the role of auditors.

Practical implications

This research has several practical implications. First, firms seeking to raise debt capital should consider involving auditors, with either industry expertise or fair value expertise, due to the roles that auditors play in safeguarding the reliability of fair value measures, particularly for Level 3 measurements. Second, from standard-setting and regulatory perspectives, the study’s findings that fair value accounting is associated with higher bond yield spread cast further doubt on the net benefits of applying a full fair value accounting regime. Third, PCAOB may consider enhancing guidance to auditors on Level 2 fair value inputs, to further enhance audit quality. Finally, creditors can be more cautious in interpretating accounting information based on fair value while viewing the employment of auditor experts as a positive signal.

Originality/value

First, the paper extends research on the role of accounting information in public debt contracting. Second, this study adds to the auditing literature about the impact of industry expertise. Finally, and more generally, this study adds to the ongoing controversy on the application of fair value accounting.

Abstract

Purpose

The purposes of this paper are to prepare the carbon nanotube (CNT) grease, to contrast the tribology properties of the CNT grease with the original grease and to find the lubricating mechanism of the CNT grease.

Design/methodology/approach

The CNTs (single-wall and multi-wall) are added into the polyalphaolefin oils (DURASYN_166) to form stable and homogeneous CNT grease with potential heat transfer, conductive and lubricative properties. The friction of this new type of CNT grease was determined by wear experiments under three conditions: dry friction, with the base oil grease and with the CNT grease.

Findings

The research is about the tribological properties of CNT greases; it shows better lubricating performance and wear resistance than the base oil grease. The performance improvement of CNT grease is owing to the unique hexagonal structure and the high thermal conductivity of CNTs.

Originality/value

The paper documents that CNTs can obviously improve the lubricating effect of grease, and the lubricating mechanism of the CNT grease is also discussed.

Abstract

Purpose

The authors develop a theoretical framework of how foreign competition in a firm's home country jointly interacts with other environmental factors to influence the internationalization pace. This study moves beyond the debate on whether foreign competition promotes or inhibits the internationalization pace by unpacking the nature of pace across strategic and operational dimensions. By differentiating the internationalization paces of market scope and international commitment, the study results show that foreign competition has a positive effect on the former and a negative effect on the latter. This indicates that the determinants of different paces are conditional upon the different knowledge types among foreign competitors.

Design/methodology/approach

Using a panel data set of Chinese construction corporations over the period from 2009 to 2015, the authors extend previous research on the effect of home country environment on internationalization behavior in an emerging economy by examining the effects of the interplay between foreign competition in home country and industrial contexts. The authors also explore the moderating effect of subnational institutions on the relationship between foreign competition and internationalization pace. They use a Poisson model and a GEE model to examine the main effects and moderating effects involved.

Findings

The results indicate that industry dynamism strengthens the positive effect of foreign competition and the pace of market scope, while industry munificence weakens the negative effect of foreign competition and the pace of international commitment. The authors’ findings support the coexistence of “pushing” and “pulling” effects of environmental factors from a firm's home country. The authors extend the argument of “institutional escapism” by focusing on subnational institutions. They show that firms located in a region with a low level of marketization are more likely to respond by accelerating the pace of their international expansion to escape from their home country.

Originality/value

The authors’ findings have implications for practitioners and policymakers working with emerging market firms (EMFs). The authors suggest that local governments should consider building high-quality institutions that can reduce the possibility of investment opportunities escaping EMFs. The authors’ findings indicate that international knowledge from foreign competitors may also assist EMFs in understanding more about the cultural environment before entering host countries, although it cannot help them to resolve cultural uncertainty when operating in host countries. Hence, managers should carefully evaluate their competitiveness before they decide to engage in global competition at an accelerated rate.

Abstract

Purpose

Due to the frequent occurrence of data breaches, managing the cost of these events has become one of the biggest challenges confronting modern businesses. Firms urgently require strong security and effective event response strategies to tackle data breaches.

Design/methodology/approach

This study first quantified the cost of 196 data breach events between 2016 and 2019 using the event study method and then utilized the crisp-set qualitative comparative analysis (csQCA) method to investigate the influencing mechanisms of the data breach cost from the configured perspectives of firm, event and response strategy.

Findings

The results of the event study revealed significant differences in the cost of data breaches and their influencing factors between traditional and Internet-based firms. While Internet-based firms tended to experience a negative market reaction following a data breach, traditional firms did not show the same pattern. Based on the configuration analysis, six different strategies for cost control were identified, including mitigation and apology strategies for internet-based firms and indifference, fact-statement, silence-keeping and reputation-building strategies for traditional firms.

Originality/value

The findings of this study can provide deeper insights into the market reaction to data breach events as well as their influencing mechanisms. Furthermore, this study offers practical suggestions for corporations to manage and control the strikes of data breach incidents.

Abstract

Several multivariate statistical methods were comprehensively used to interpret the temporal, spatial patterns and source identification of surface water pollution in Bohai Bay with the large and complex data. Twelve variables water quality indices were surveyed at 12 sites three times a year (May, August, and October) from 1995 to 2005. Cluster analysis (CA) grouped the eleven years into two clusters, Cluster A (1995 to 2001 except 1998) and cluster B (2002 to 2005 and 1998), and spatial CA divided the entire area into three groups. The results of discriminant analysis showed that the temporal CA and spatial CA were effective with 90% and 83.3% correct assignments, respectively. In cluster A, the pollution sources mainly were nutrient factor from non-point source and Hg pollution, oil and organic pollutions were relatively light. In Cluster B, the organic pollution became the mainly pollution source, and the nutrient pollution was still serious problem. In the results of spatial analysis, the group 1 was mainly affected by anthropogenic pollution, the group 3 was seriously affected by oil spill pollution and nutrients pollution, and the group 2 reflected relatively strong water self-purification ability.

Abstract

Purpose

The purpose of this paper is to further explore the co-citation and bibliographic-coupling relationship among the core authors in the field of Chinese information science (IS), to expose research activity and author impact, and to make induction analyses about Chinese IS research patterns and theme evolution.

Design/methodology/approach

The research data include 8,567 papers and 70,947 cited articles in the IS field indexed by Chinese Social Sciences Citation Index from 2000 to 2009. Author co-citation analysis, author bibliographic-coupling analysis, social network analysis, and factor analysis were combined to explore co-citation and bibliographic-coupling relationships and to identify research groups and subjects.

Findings

Scholars with greatest impact are different from the most active scholars of Chinese IS; there is no uniform impact pattern forming since authors’ impact subjects are scattered and not steady; while authors’ research activities present higher independence and concentration, there is still no steady research pattern due to no deep research existing. Furthermore, Chinese IS studies can be delineated by: foundation or extension. The research subjects of these two parts, as well as their corresponding/contributing authors, are different under different views. The general research status of core authors is concentrated, while their impact is broad.

Originality/value

The combined use of some related methods could enrich the development and methodology research of the discipline, and the results establish a reference point on the development of IS research.

Abstract

Purpose

The purpose of this study is to explore the feasibility of utilizing agricultural (almond shell, rice husk and wood) waste biochars for partial cement replacement by evaluating the relationships between the physiochemical properties of biochars and the early-age characteristics of cement pastes.

Design/methodology/approach

Biochars are prepared through the thermal decomposition of biomass in an inert atmosphere. Using varying percentages, biochars are used to replace ordinary Portland cement (OPC) in cement pastes at a water/binder ratio of 0.35. Characterization methods include XPS, FTIR, SEM, TGA, BET, Raman, loss-on-ignition, setting, compression and water absorption tests.

Findings

Accelerated setting in biochar-modified cement pastes is attributed to chemical interactions between surface functional groups of biochars and calcium cations from OPC, leading to the early development of metal carboxylate and alkyne salts, alongside the typical calcium-silicate-hydrate (C-S-H). Also, metal chlorides such as calcium chlorides in biochars contribute to the accelerate setting in pastes. Lower compression strength and higher water absorption result from weakened microstructure due to poor C-S-H development as the high carbon content in biochars reduces water available for optimum C-S-H hydration. Amorphous silica contributes to strength development in pastes through pozzolanic interactions. With its optimal physiochemical properties, rice-husk biochars are best suited for cement replacement.

Research limitations/implications

While biochar parent material properties have an impact on biochar properties, these are not investigated in this study. Additional investigations will be conducted in the future.

Practical implications

Carbon/silicon ratio, oxygen/carbon ratio, alkali and alkaline metal content, chlorine content, carboxylic and alkyne surface functional groups and surface areas of biochars may be used to estimate biochar suitability for cement replacement. Biochars with chlorides and reactive functional groups such as C=C and COOH demonstrate potential for concrete accelerator applications. Such applications will speed up the construction of concrete structures and reduce overall construction time and related costs.

Social implications

Reductions in OPC production and agricultural waste deterioration will slow down the progression of negative environmental and human health impacts. Also, agricultural, manufacturing and construction employment opportunities will improve the quality of life in agricultural communities.

Originality/value

Empirical findings advance research and practice toward optimum utilization of biomass in cement-based materials.
