The purpose of this paper is to construct an index for systemic risk in China.
Abstract
Purpose
The purpose of this paper is to construct an index for systemic risk in China.
Design/methodology/approach
This paper develops a systemic risk index for China (SRIC) using textual information from 26 leading newspapers in China. Our index measures the systematic risk from 21 topics relating to China’s economy and provides narratives of the sources of systemic risk.
Findings
SRIC effectively predicts changes in GDP, aggregate financing to the real economy and the purchasing managers’ index. Moreover, SRIC explains several other commonly used macroeconomic indicators. Our risk measure provides a helpful monitoring tool for policymakers to manage systemic risk.
Originality/value
The paper construct an index of systemic risk based on the information extracted from newspaper articles. This approach is new to the literature.

This study investigated the asymmetric effects of changes in policy uncertainty on real sector variables in Brazil, China, India and South Africa.
Abstract
Purpose
This study investigated the asymmetric effects of changes in policy uncertainty on real sector variables in Brazil, China, India and South Africa.
Design/methodology/approach
The study used the nonlinear autoregressive distributed lag (NARDL) modeling framework.
Findings
The results showed that both in the long run and short run, rising uncertainty not only increases consumer prices significantly in these economies, but also impedes aggregate and sectoral output growths, and deters investment, employment and private consumption. Contrary to economic expectation, the results also showed that in the long run, declining uncertainty impedes aggregate and sectoral output growths in these economies, and significantly hinders employment in South Africa and Brazil. This suggests that in the long run, economic agents in these economies somewhat behave as if uncertainty is rising. The authors also found significant asymmetric effects in the response of real sector variables to uncertainty both in the long run and short run, which justifies the choice of NARDL framework for this study.
Research limitations/implications
The sample is limited to Brazil, India, China and South Africa. While Brazil, India and China are three of the most prominent large emerging market economies, South Africa is the largest emerging market economy in Africa.
Practical implications
To lessen the adverse effects of policy uncertainty observed in the results, there is need for sound institutions and policy regimes that can promote predictable policy responses in these economies so that policy neither serves as a source of uncertainty nor as a channel through which the effects of other shocks are transmitted.
Originality/value
Apart from using the NARDL framework to capture the asymmetric effects of policy uncertainty, this study also accounted for the sectoral effects of uncertainty in emerging markets.

Abstract
Purpose
In Hong Kong, over 20,000 private residential buildings will be 50 plus years old by 2039. However, building maintenance has not been owners’ popular interest because of the high cost as well as the complexities in justifying whether the quantities and prices of the maintenance works are reasonable. This paper therefore aims to validate the practicality of adopting Scan-to-BIM: Terrestrial Laser Scan (TLS) and Building Information Modelling (BIM) to perform quantity take-offs (QTO) for estimating building maintenance costs.
Design/methodology/approach
A 64-year-old tenement building was selected to conduct a case study. In this instance, the building had undergone a Scan-to-BIM survey approach to generate QTO for the bills of quantities for external painting works. The Scan-to-BIM approach includes site visit, positioning of scanning equipment, assignment of circular scan routes, point cloud registration and identification of residual error. After that, time, cost and quality data were logged into contrast with QTO on as-built plans for external wall plastering works.
Findings
The “time”, “cost” and “quality” of the Scan-to BIM practice were then examined and compared with the prevailing practices of manual measurements on as-built drawings. As noted from the results, the initial cost of Scan-to BIM is high, owing to the cost of equipment, software and capable available operators. However, the authors identified that the time and cost can be significantly minimised by developing and implementing efficient practices such as preparing a detailed scan plan, equipping modeller with quantity surveying knowledge, using automated object recognition and 5D BIM software packages such as Vico Office and CostX.
Practical implications
The upshot is that Scan-to-BIM could be one of the measures to advance the clarity in the QTO and estimated price of the maintenance projects.
Originality/value
The practicability of Scan-to-BIM has received limited attention on existing building maintenance project. The Scan-to-BIM approach was examined using a case building of a 64-year-old tenement building. The approach demonstrated in this research study is promised to advance the clarity in the QTO and estimated price of maintenance project.

Abstract
Purpose
In the current study based on the resource-based view (RBV), a three-way interaction model tests the relationships among human and social capital resources, innovation orientation (IO) and innovation capability in the context of new ventures.
Design/methodology/approach
Hierarchical linear regression modeling presents the linear relations at two decision layers of start-ups, their founders and managers. Data is collected and analyzed from 233 new ventures in Turkey.
Findings
Findings of the two and three-way interaction analyses indicate a positive relationship between human capital and innovation capability when social capital and IO are high; however, the relation turns off when low.
Research limitations/implications
The study extends the previous works on the proposed link between intellectual capital (IC) resources and innovation, by confirming the moderating role of social capital and IO on the positive association between human capital resources and innovation capability.
Practical implications
The results show that for start-up companies, the co-existence of strong social capital and the strategic orientation towards innovation is required for the effective utilization of human capital for generating innovation capability within the organization. Thus, this study highlights the importance of networks, alliances and social relationships, together with the unification of strategic thinking, organizational learning and a culture of innovation for attaining innovation goals, which are crucial for the survival and success of these units.
Originality/value
This study presents the first model in the literature which examines the moderating effects of IO and social capital on the human capital-innovation capability relationship.

Abstract
Purpose
This study aims to use emotions-as-social information theory to investigate how physical (customer perceived store atmosphere) and social servicescapes (customer information searching) influence the effects of employees’ positive affective displays on customer outcomes via customer positive moods and positive expectation disconfirmation.
Design/methodology/approach
This research included two studies, each using a distinct research design, to empirically test the proposed model. Study 1 involved 200 observational data points on objective purchase amounts from designer watch shops. In Study 2, data were collected from 230 customers in designer jewelry stores.
Findings
The results of path analyses revealed that: employee positive affective displays are positively associated with customer purchase outcomes; employee positive affective displays had positive indirect effects on customer purchase outcomes by enhancing customer positive moods and positive expectation disconfirmation; these positive indirect effects were strengthened when customers engaged in information search behaviors; and these positive indirect effects were attenuated when customers perceive store atmosphere as favorable, indicating a substitution effect of customer perceived store atmosphere.
Originality/value
Previous research has not thoroughly examined the role of the servicescape in moderating the effects of employees’ positive affective displays on customer purchase outcomes. This present study not only clarified the affective and cognitive mechanisms that link employees’ positive affective displays on purchase outcomes but also identified servicescape as a critical boundary condition of these effects.

Abstract
Purpose
Propagation characteristics of millimeter wave (mmW) frequencies that are being explored for implementing 5G network are quite different from sub 3GHz frequencies in which 4G network is operating, and hence antenna design for mmW 5G network is going to be significantly different. The purpose of this paper is to bring forth the unique challenges and opportunities of planar antenna design for mmW 5G network.
Design/methodology/approach
A lot of notable contemporary work has been investigated for this study and reported in this paper. A comparison of 4G and 5G technologies has been carried out to understand the difference between the air interface of two technologies that governs the antenna design. Important research gaps found after collating the work already done in the field have been bullet pointed for the use by many researchers working in this direction.
Findings
Several antenna design considerations have been laid out by the authors of this work, and it has been claimed that mmW 5G antenna design must satisfy these design considerations. In addition, prominent research gaps have been identified and thoroughly discussed.
Originality/value
As research in the field of mmW antenna design for 5G applications is still evolving, a lot of work is currently being done in this area. This study can prove to be important in understanding different challenges, opportunities and current state-of-art in the field of mmW planar antenna design for 5G cellular communication.

Abstract
Purpose
The purpose of this research is twofold; firstly, to propose and test a measuring instrument for the efficient and effective integration of management systems (MSs), identifying the particular aspects that may distinguish the substantive (internalized) from the superficial (ceremonial) integration; and secondly, to propose and test a scale for corporate sustainability performance (CSP).
Design/methodology/approach
A literature review has identified pertinent variables and yielded relevant measuring items. A field survey has been conducted. The survey instrument has been administered to Greek organizations certified to two or more MS standards. Collected data from 280 respondents has been processed using exploratory factor analysis.
Findings
Internalization has been identified as the main construct to interpret substantial MS integration in terms of resources and the extent of integration. The extracted internalization factors are human resources, strategic resources, information systems, integration tools, outsourcing, internal processes integration level and audits' integration level. CSP has been operationalized in terms of the company's relationships with its stakeholders. The extracted CSP factors are customer–supplier relationship, the employees, investors/shareholders, financial institutions, the environment, state and society.
Practical implications
This research findings can be used by management professionals, certification bodies and governmental authorities in order to foster the implementation of multiple MSs and highlight the critical issues for their successful integration and internalization, which is imperative for their prosperity and contribution toward CSP. Practitioners are also provided with an instrument to monitor CSP through the company's relationships with its stakeholders toward satisfaction of their needs.
Originality/value
To the best of the authors' knowledge, this is the first empirical study on the internalization of integrated MSs. In addition, the development of a CSP scale intends to bring together corporate sustainability management with CSP.

Abstract
Purpose
Due to the unknown location, size and timing of disasters, the rapid response required by humanitarian operations (HO) faces high uncertainty and limited time to raise funds. These harsh realities make HO challenging. This study aims to systematically capture the complex dynamic relationships between operations in humanitarian settings.
Design/methodology/approach
To achieve this goal, the authors undertook a systematic review of the extant academic literature linking HO to system dynamics (SD) simulation.
Findings
The research reviews 88 papers to propose a taxonomy of different topics covered in the literature; a framework represented through a causal loop diagram (CLD) to summarise the taxonomy, offering a view of operational activities and their linkages before and after disasters; and a research agenda for future research avenues.
Practical implications
As the authors provide an adequate representation of reality, the findings can help decision makers understand the problems faced in HO and make more effective decisions.
Originality/value
While other reviews on the application of SD in HO have focused on specific subjects, the current research presents a broad view, summarising the main results of a comprehensive CLD.

Abstract
Purpose
Purpose: The main purpose of the study is to understand the factors that facilitate correction behavior among individuals. In this study the authors examine the impact of self-perceived media literacy (SPML) and reflection on participants’ correction behavior.
Design/methodology/approach
Methods: Data for the study were collected from Amazon's MTurk using an online survey. Data were collected after a certificate of exemption was received by the Institutional Review Board in a research university in the United States (US) Qualtrics software was used to collect data. The total number of participants was 797.
Findings
Findings: The findings show that although both SPML and reflection are positively associated with rumor refutation, higher SPML alone is not enough. Reflective judgment is critical for individuals to take part in this behavior online, such that individuals with higher reflective judgment indicated that they refute rumors online, irrespective of their SPML score.
Originality/value
Originality: The authors tested the relationship of multiple variables with participants correction behavior. Although research shows the importance of social correction, there is not much knowledge about what facilitates actual misinformation correction.
