Abstract

Purpose

This study aims to identify the level of security from existing work, analyze categories of security as a service (SECaaS) and classify them into a meaningful set of groups. Further, the report will advise commercial applications and advice of SECaaS as an extended context to help firms make decisions.

Design/methodology/approach

This paper compares the SECaaS categories in Cloud Security Alliance (CSA) with the security clauses in ISO/IEC 27002:2013 to give a comprehensive analysis of those SECaaS categories. Reviewed from a number of related literature, this paper analyzes and categorizes SECaaS into three major groups including protective, detective and reactive based on security control perspectives. This study has discussed the three groups and their interplay to identify the key characteristics and problems that they aim to address.

Findings

This paper also adds new evidence to support a better understanding of the current and future challenges and directions for SECaaS. Also, the study reveals both the positive and negative aspects of SECaaS along with business cases. It advises on various sizes and domains of organizations to consider SECaaS as one of their potential security approaches.

Originality/value

SECaaS has been demonstrated to be one of the increasingly popular ways to address security problems in Cloud computing. As a new concept, SECaaS could be treated as integrated security means and delivered as a service module in the Cloud. However, it is still in infancy and not very widely investigated. Recent studies suggest that SECaaS is an efficient solution for Cloud and real industries. However, shortcomings of SECaaS have not been well-studied and documented. Moreover, reviewing the existing research, researchers did not classify the SECaaS-related categories.

Abstract

Purpose

Polyurethane concrete (PUC), as a new type of steel bridge deck paving material, the bond-slip pattern at the interface with the steel plate is not yet clear. In this study, the mechanical properties of the PUC and steel plate interface under the coupled action of temperature, normal force and tangential force were explored through shear tests and numerical simulations. An analytical model for bond-slip at the PUC/steel plate interface and a predictive model for the shear strength of the PUC/steel plate interface were developed.

Design/methodology/approach

The new shear test device designed in this paper overcomes the defect that the traditional oblique shear test cannot test the interface shear performance under the condition of fixed normal force. The universal testing machine (UTM) test machine was used to adjust the test temperature conditions. Combined with the results of the bond-slip test, the finite element simulation of the interface is completed by using the COHENSIVE unit to analyze the local stress distribution characteristics of the interface. The use of variance-based uncertainty analysis guaranteed the validity of the simulation.

Findings

The shear strength (τf) at the PUC-plate interface was negatively correlated with temperature while it was positively correlated with normal stress. The effect of temperature on the shear properties was more significant than that of normal stress. The slip corresponding to the maximum shear (D1) positively correlates with both temperature and normal stress. The interfacial shear ductility improves with increasing temperature.

Originality/value

Based on the PUC bond-slip measured curves, the relationship between bond stress and slip at different stages was analyzed, and the bond-slip analytical model at different stages was established; the model was defined by key parameters such as elastic ultimate shear stress τ0, peak stress τf and interface fracture energy Gf.

Abstract

Purpose

The purpose of this paper is to explore the influencing mechanism of coaching leadership (CL) on employee voice behavior (VB) based on cognitive-affective system theory of personality (CAPS). Specifically, the study intends to build a model of psychological security (PS) and openness to change (OC) that mediate the relationship between CL and employee VB at an individual-level and group-level from cognitive-affective dual perspective.

Design/methodology/approach

CL, employee VB, PS and OC were assessed in an empirical study based on a supervisor–subordinate dyads sample of 287 employees and 72 team leaders from enterprises in Southern China.

Findings

From CAPS theory perspective, the authors found that CL promotes employee VB and that PS and OC mediate the relationship between CL and VB.

Practical implications

Results underscore the importance of encouraging managers to engage in CL behaviors, which are conductive to enhancing employee PS and OC thereby improving employee VB. These results also highlight the significance of managerial attention to a secure voice atmosphere and the improvement of employees’ affective commitment to organizational change.

Originality/value

The research findings provide a significant contribution to the literature in that it shows PS and OC as crucial dual mediating mechanism through which CL influences VB. Moreover, this paper is one of the few studies answering the call to examine the effect of leadership at multiple levels.

Abstract

Purpose

This study focuses on how entrepreneurial bricolage (EB) drives both competitive advantage (CA) and sustainability performance (SP).

Design/methodology/approach

Relying on structural equation modeling, data were collected from 200 small and medium-sized enterprise (SME) manufacturers in Ghana.

Findings

The results indicate that EB drives both CA and SP positively. SL positively moderated the relationship between EB and CA, while the moderating role of SL in the relationship between EB and SP was not supported.

Originality/value

The study concludes that EB can enhance SP, a notion prior study grossly overlooked.

Abstract

Purpose

The purpose of this paper is to verify the feasibility of lunar capture braking through three methods based on particle swarm optimization (PSO) and compare the advantages and disadvantages of the three strategies by analyzing the results of the simulation.

Design/methodology/approach

The paper proposes three methods to verify capture braking based on PSO. The constraints of the method are the final lunar orbit eccentricity and the height of the final orbit around the Moon. At the same time, fuel consumption is used as a performance indicator. Then, the PSO algorithm is used to optimize the track of the capture process and simulate the entire capture braking process.

Findings

The three proposed braking strategies under the framework of PSO algorithm are very effective for solving the problem of lunar capture braking. The simulation results show that the orbit in the opposite direction of the trajectory has the most serious attenuation at perilune, and it should consume the least amount of fuel in theoretical analysis. The methods based on the fixed thrust direction braking and thrust uniform rotation braking can better ensure the final perilune control accuracy and fuel consumption. As for practice, the fixed thrust direction braking method is better realized among the three strategies.

Research limitations/implications

The process of lunar capture is a complicated process, involving effective coordination between multiple subsystems. In this article, the main focus is on the correctness of the algorithm, and a simplified dynamic model is adopted. At the same time, because the capture time is short, the lunar curvature can be omitted. Furthermore, to better compare the pros and cons of different braking modes, some influence factors and perturbative forces are not considered, such as the Earth’s flatness, light pressure and system noise and errors.

Practical implications

This paper presents three braking strategies that can satisfy all the constraints well and optimize the fuel consumption to make the lunar capture more effective. The results of comparative analysis demonstrate that the three strategies have their own superiority, and the fixed thrust direction braking is beneficial to engineering realization and has certain engineering practicability, which can also provide reference for lunar exploration orbit design.

Originality/value

The proposed capture braking strategies based on PSO enable effective capture of the lunar module. During the lunar exploration, the capture braking phase determines whether the mission will be successful or not, and it is essential to control fuel consumption on the premise of accuracy. The three methods in this paper can be used to provide a study reference for the optimization of lunar capture braking.

Abstract

Purpose

How to foster voice behavior has always been a hot topic in organizational research; however, the mechanism through which performing decent work affects employee voice behavior remains to be fully understood. To address this deficiency, the current study investigates how basic need satisfaction may relate to perceived decent work and voice behavior and the moderating role of gender. Our research draws upon self-determination theory and social information processing theory.

Design/methodology/approach

The theoretical model was tested using two-wave investigation data collected from a sample of 349 employees and 85 supervisors in Southwest China.

Findings

Decent work perception was positively related to voice behavior, and this relationship was partially mediated by basic need satisfaction. In addition, the relationship between decent work perception and basic need satisfaction as well as the indirect effect of decent work perception on voice behavior via basic need satisfaction was stronger for men than for women.

Originality/value

This study highlights the pivotal roles of basic need satisfaction and gender in the consequences of decent work perception in the workplace. The authors provide new insights into the relationship between decent work perception and voice behavior and inspire scholars to elucidate other explanatory mechanisms in this link.

Abstract

Purpose

It is unclear what constitutes the tourism live streaming (TLS) servicescape and how it affects users' travel intention (TI). The study aims to explore the composition of the TLS servicescape, the influence mechanism of the TLS servicescape on users' TI and the formation of users' TI.

Design/methodology/approach

Based on stimulus organism response theory (SOR), we develop a mediation model to explore the influence of TLS servicescape on users' TI. This study collected data from 432 Chinese TLS users through an online questionnaire, and we used the structural equation model and the SPSS PROCESS macro to test the proposed model. In addition, we tested the variable relationships using fuzzy-set qualitative comparative analysis (fsQCA).

Findings

TLS servicescape is a second-order variable that can be categorized into physical element (PE), social element (SOE), symbolic element (SYE) and natural element (NE). TLS servicescape influences TI by affecting social presence (SP) and customer engagement (CE). The fsQCA reveals seven combinations of PE, SOE, SYE, NE, SP and CE that form a high TI for TLS users.

Originality/value

Using multiple data analysis methods, the study emphasizes the significance of the TLS servicescape for TLS. It explores how to evoke users' TI in TLS and provides a reference for TLS marketing.

Abstract

Purpose

The purpose of this study is to improve the surface electrical conductivity and corrosion resistance of AISI430 stainless steel (430 SS) as bipolar plates for direct formic acid fuel cell (DFAFC).

Design/methodology/approach

The niobium diffusion layers have been successfully synthesized on 430 SS substrate by the plasma surface diffusion alloying technique under different diffusion alloying time.

Findings

The surface morphology of Nb-modified 430 SS prepared under the diffusion alloying time of 2 h is more homogeneous, relatively sleek and compact without surface micropore and other common surface blemishes. The potentiostatic and potentiodynamic polarization measurements manifest that Nb-modified 430 SS prepared under the diffusion alloying time of 2 h enormously ameliorate the corrosion resistance of bare 430 SS compared with other Nb-modified 430 SS samples and its corrosion current density is maintained at −1.4 µA cm−2 in simulated anodic environment of DFAFC (0.05 M H2SO4 + 2 ppm HF + 10 M formic acid at 50 °C).

Originality/value

The effect of diffusion alloying time on the corrosion resistance and surface conductivity of Nb-modified 430 SS has been carefully studied. The Nb-modified 430 SS samples prepared at the diffusion alloying time of 2 h have the best surface electrical conductivity and corrosion resistance in the simulated anodic environment of DFAFC.

Abstract

Purpose

Business ecosystem is described as a web of loose relationships, thereby posing some challenges to coordination. In attempt to ensure coordination in business relationships, scholars have proposed relational and contractual governance mechanisms. Hence, this study aims to examine the effects of governance mechanisms on coordination in the pharmaceutical business ecosystem (BE), with the potential mediating effects of closeness and opportunistic behavior.

Design/methodology/approach

The study adopted quantitative approach with cross-sectional survey research design to collect data from the business ecosystem of pharmaceutical company X in Ghana. A structured questionnaire based on a five-point Likert scale was employed to collect data. Analysis was based on 173 institutions (both local and international) selected from pharmaceutical BE. Various validity and reliability checks were conducted before the presentation of the actual analysis, which was conducted using ordinary least squares (OLS) regression in Statistical Product and Service Solutions (SPSS).

Findings

The results of the study revealed that both relational and contractual governance have a direct positive effect on coordination between pharmaceutical BE members and the focal firm. The effect of contractual governance on coordination is however, partially mediated by opportunistic behavior. Finally, closeness also fully mediated the effect of relational governance on coordination.

Originality/value

The study builds on the governance mechanisms in exchange relationship, which was hitherto largely limited to the dyadic and triadic business network, partnerships and strategic alliances studies. The contribution to BE literature provides further understanding into transaction cost economics and relational exchange theory, which was dominantly applied in dyadic relationships ties such as partnerships, alliances and networks.

Abstract

Purpose

While much research has examined the effect of media literacy in combatting misinformation, whether and to what extent news media literacy influences misinformation-related behaviors (i.e. misinformation sharing, misinformation correction) and the mediating effect of news media skepticism in the process remain less explored. Moreover, this line of research has extensively focused on a polarized information context (e.g. the USA) with less attention to a context where news information is more regulated and centralized. This paper aims to discuss the aforementioned objective.

Design/methodology/approach

The authors conducted a survey study of 720 Chinese adults.

Findings

This study reveals that greater new media literacy predicts higher misinformation correction behaviors, but fails to predict caution in sharing misinformation. Findings further demonstrate a nuanced mediating effect of news media skepticism that challenges previous assertions about its protective role. That is, higher news media literacy is associated with lower news media skepticism; lower skepticism is in turn related to lower misinformation sharing and greater misinformation correction.

Originality/value

The current study integrates news media literacy and news media skepticism in understanding misinformation-related behaviors. Findings generally speak to the tangible benefits of news media literacy in helping motivate corrective actions among the general public. However, this study also strikes a cautious note that future investigations of news media skepticism would benefit from a cultural perspective. Its connections with perceptions and effects on behaviors could vary according to different types of media and political landscapes.
