Abstract

Purpose

The purpose of this paper is to take advantage of Internet of Things (IoT) for intelligent route programming of crowd emergency evacuation in metro station. It is a novel approach to ensure the crowd safety and reduce the casualties in the emergency context. An evacuation route programming model is constructed to select a suitable evacuation route and support the emergency decision maker of metro station.

Design/methodology/approach

The IoT technology is employed to collect and screen information, and to construct an expert decision model to support the metro station manager to make decision. As a feasible way to solve the multiple criteria decision-making problem, an improved multi-attributive border approximation area comparison (MABAC) approach is introduced.

Findings

The case study indicates that the model provides valuable suggestions for evacuation route programming and offers practical support for the design of an evacuation route guidance system. Moreover, IoT plays an important role in the process of intelligent route programming of crowd emergency evacuation in metro station. A library has similar structure and crowd characteristics of a metro station, thus the intelligent route programming approach can be applied to the library crowd evacuation.

Originality/value

The highlights of this paper are listed as followings: the accuracy and accessibility of the metro station’s real-time information are improved by integrating IoT technology with the intelligent route programming of crowd emergency evacuation. An improved MABAC approach is introduced to the expert support model. It promotes the applicability and reliability of decision making for emergency evacuation route selection in metro station. It is a novel way to combine the decision-making methods with practice.

Abstract

Purpose

This comparative study aims to examine the role of Socio-Economic Status (SES) on the academic performance of university students who hold both the status of Residential College (RC) and non-RC. The study further investigates whether the RC is able to offset the effects of SES on students' learning performance to ensure education equity and inclusion in China.

Design/methodology/approach

Data are collected through a questionnaire given to RC and non-RC students enrolled in three public universities in China. A quasi-experimental design is implemented to investigate the potential correlation, if any, between SES, RC and academic performance.

Findings

The results reveal that SES influences academic performance of RC students. Furthermore, the findings strongly suggest that RCs negatively moderate the effect of SES on academic performance.

Research limitations/implications

This study examines RCs within a specific type of university in China, which may limit the generalizability of findings. Additionally, it uses a quasi-experimental method and relies solely on quantitative data, which may also introduce limitations.

Practical implications

Provided in this study is evidence that RCs can be an innovative way to bolster inclusive and equitable quality education for students from diverse backgrounds in China.

Originality/value

This study enriches the existing literature by exploring the relationships between RC, SES and academic performance in China. In addition, it provides significant references to whether RC can fulfill students' education equity and inclusion.

Abstract

Purpose

Community governance plays an important role in the prevention and control of the Coronavirus disease 2019 (COVID-19) pandemic in China. Community workers, the main executors in community governance, experience a huge amount of stress, which affects their physical and mental health. Thus, it is crucial to pay more attention to the stressors and stress responses of community workers and propose strategies to alleviate such responses. This paper aims to analyze the work stress of community workers during the COVID-19 pandemic in China.

Design/methodology/approach

Based on a questionnaire survey of 602 community workers during COVID-19 in China, the four main stressors and 14 stress factors of community workers were identified and six factors at three levels of stress responses were defined. A stress analysis model is proposed that tests the mediating role of psychological capital and the moderating role of organizational climate.

Findings

The results show that stressors influence stress responses through the moderating role of psychological capital, organizational climate plays a negative mediator role between stressors and psychological capital and the main stressors for community workers are work, safety and performance stress.

Originality/value

This paper contributes to existing research because it offers suggestions for reducing the impact of stress on the community workers during the COVID-19 pandemic. Further, it can promote the control and prevention of the COVID-19.

Abstract

Purpose

In the face of major disasters, the Chinese people's willingness to donate has increased and the result is that the donation paths have increased. However, there are certain differences in the choice of donation paths for different types of individuals. It is crucial to pay more attention to the attitude and donation path selection of donors and propose strategies to promote individual donation behavior. The purpose of this study is to propose a conceptualized moderated mediation model for testing the linkage between individual attitude and donation path selection through the mediating effect of donors' behavioral intention and the moderating effect of behavioral difficulty perception or social pressure between donors' attitude and their donation path selection.

Design/methodology/approach

Based on a questionnaire survey of 628 community workers during COVID-19 in China. Self-reported measures were used to obtain data on IA, BI, SP, BDP and DPS. Survey data were used to test the proposed model using hierarchical regression analysis. Mediation analyses with bootstrap via PROCESS were used to ascertain the proposed relationship.

Findings

The results showed that individual attitude are positively related to donation path selection. Moreover, this study finds that behavioral intention serves as a mediator in the relationships between individual attitude and donation path selection. The social pressure and behavioral difficulty perception negatively moderate the relationship between individual attitude and behavioral intention.

Research limitations/implications

There are still some shortcomings in this study: First, although the data collected at multiple points in this study are all individual data. Future research can add evaluations of relatives, friends or colleagues to individual scheduling of survey subjects to reduce homology errors. Second, although this study has verified the mediating role of the opposite sex, some of the mediating results show that there may be other variables that play a role in the relationship between individual attitudes and donation path selection. In the research on path selection, the integrated theoretical perspective has rich connotations but has not attracted enough attention from the academic community. This research is only based on this single theoretical perspective to construct, verify and explain the model, and there should be other integrated theories. The fit point can be used to analyze the influence mechanism of individual attitudes on the choice of donation path.

Practical implications

First of all, we must deepen our understanding of the connotation and role of individuals' attitudes. In the event of a major epidemic, the following two types of measures will be taken to improve individuals' attitudes toward specific donation paths: First, the sponsors of each donation should do their best to donors and provide more information about donations, because the more information resources they have, the stronger the experience of the corresponding donation path, and the more they will choose the path. The sponsor of the second donation must show concern for major epidemics that are prone to occur and a desire to help people affected by disasters, so as to enhance the emotional identity of the donor, thereby increasing the probability of the donor choosing a specific donation path. Secondly, donation sponsors should be wary of the negative influence of social pressure on the donation path selection of individual donors. Donation sponsors can train individuals who are willing to donate, guide them in social relations, online public opinion and other pressure methods and improve the possibility of individuals choosing specific donation routes.

Social implications

Deepen the understanding of the content and effectiveness of the behavioral difficulty perception that has a profound impact on the donor. The greater the tendency to make a path choice is often affected by the individual's perception of the difficulty of behavior. The perception of difficulty of a certain donation path will cause the individual to retreat and inhibit the possibility of the individual choosing the path. Therefore, donation sponsors should take all measures to make their own donation channels simpler and more efficient, thereby reducing the individual's perception of the difficulty of donation behavior.

Originality/value

Drawing on TPB theory, a theoretical framework is constructed that specifies the process through which individual attitude affects donation path selection to expand collective understandings of individual attitude in the donation context. Furthermore, the boundary conditions of the underlying process are investigated, which further enhances the contribution of this paper to the extant literature on individual attitude.

Abstract

Purpose

This study aims to consider active vision in low-visibility environments to reveal the factors of optical properties which affect visibility and to explore a method of obtaining different depths of fields by multimode imaging.Bad weather affects the driver’s visual range tremendously and thus has a serious impact on transport safety.

Design/methodology/approach

A new mechanism and a core algorithm for obtaining an excellent large field-depth image which can be used to aid safe driving is designed and implemented. In this mechanism, atmospheric extinction principle and field expansion system are researched as the basis, followed by image registration and fusion algorithm for the Infrared Extended Depth of Field (IR-EDOF) sensor.

Findings

The experimental results show that the idea we propose can work well to expand the field depth in a low-visibility road environment as a new aided safety-driving sensor.

Originality/value

The paper presents a new kind of active optical extension, as well as enhanced driving aids, which is an effective solution to the problem of weakening of visual ability. It is a practical engineering sensor scheme for safety driving in low-visibility road environments.

Abstract

Purpose

Major public cloud providers, such as AWS, Azure or Google, offer seamless experiences for infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). With the emergence of the public cloud's vast usage, administrators must be able to have a reliable method to provide the seamless experience that a public cloud offers on a smaller scale, such as a private cloud. When a smaller deployment or a private cloud is needed, OpenStack can meet the goals without increasing cost or sacrificing data control.

Design/methodology/approach

To demonstrate these enablement goals of resiliency and elasticity in IaaS and PaaS, the authors design a private distributed system cloud platform using OpenStack and its core services of Nova, Swift, Cinder, Neutron, Keystone, Horizon and Glance on a five-node deployment.

Findings

Through the demonstration of dynamically adding an IaaS node, pushing the deployment to its physical and logical limits, and eventually crashing the deployment, this paper shows how the PackStack utility facilitates the provisioning of an elastic and resilient OpenStack-based IaaS platform that can be used in production if the deployment is kept within designated boundaries.

Originality/value

The authors adopt the multinode-capable PackStack utility in favor of an all-in-one OpenStack build for a true demonstration of resiliency, elasticity and scalability in a small-scale IaaS. An all-in-one deployment is generally used for proof-of-concept deployments and is not easily scaled in production across multiple nodes. The authors demonstrate that combining PackStack with the multi-node design is suitable for smaller-scale production IaaS and PaaS deployments.

Abstract

Purpose

In response to the 2008 financial crisis, the performance of the Chinese construction industry seems to be more successful, especially in total factor productivity growth (TFPG) and its contribution (TFPGC). Hence, the purpose of this paper is to investigate and reveal the potential successful lessons in this regard.

Design/methodology/approach

This study is conducted innovatively based on a special comparative analysis of TFPG and TFPGC between pre- and post-2008 financial crisis. Solow Residual Approach is used to measure TFPG and TFPGC for the period 2002–2016. Given that the crisis hit China at the end of 2008, the pre-2008 financial crisis period is from 2002 to 2008, and the post-2008 financial crisis period is limited to 2009–2016.

Findings

The results indicate that the industry indeed has better performance in promoting TFPG and TFPGC, TFP thus achieved significant accumulative growth before and after the crisis. However, from an evolutionary perspective, both TFPG and TFPGC presented an overall downward trend from before the crisis to after the crisis. Further, the game between the centrally planned economy and the market-oriented economy was identified and revealed as the essential reason behind the evolution of TFPG and TFPGC.

Practical implications

Some valuable lessons for policies and practices in promoting TFPG and TFPGC were summarized and learned from the Chinese experience, such as reducing administrative intervention and making the construction market play a decisive role.

Originality/value

This study provides some new empirical evidence to enrich the overall body of knowledge on growth theory, especially in promoting TFPG and TFPGC.

Abstract

Compares and contrasts the contractual roles of modern waybills against the traditional straight bills of lading in the context of Greek, US and English law. Chronicles the development of international lading bills; identifies the emergence of straight bills and waybills to ameliorate the logistical problems associated with order bills of lading. Discusses the legal status and contractual roles of these lading bills in the context the legislative provisions and associated case law in each of the three countries. Concludes that sea waybills (regulating marine transport of goods) and straight bills of lading have, in essence, the same contractual status, despite the confused and unconsolidated picture of international lading provisions and practices. Recommends measures ‐ involving amendments to English legislation ‐ to consolidate the regulation of international trade.

Abstract

Following a general trend in software development, CDROM applications are increasingly implementing Graphical User Interfaces (GUIs). The general assumption is that GUIs offer advantages in terms of ease of learning and use, especially for non‐expert users. Moreover, the adoption of GUIs for CDROMs has been suggested as a means of providing a de facto standard interface. This study assesses the appropriateness of GUIs, more specifically Windows‐based interfaces for CDROM. An evaluation model was devised to carry out an expert evaluation of the interfaces of seven CDROM products. The model identified two levels of interaction, the dialogue level and task level, and focused on general interface features, search and retrieval tasks, and output and processing options as well as the help facilities. The results are discussed in the light of HCI Usability Criteria and design guidelines (including general interface design guidelines, specific Windows design guidelines and The CDROM Consistent Interface Guidelines) to assess to what extent the applications comply and appropriate recommendations are made.

Abstract

Purpose

A rapidly growing segment of the internet is e‐commerce. The future of economic competitiveness for most enterprises relies on entrance and active participation in the e‐commerce market. About a third of the time users fail when they try to purchase products on an e‐commerce site. An essential problem with e‐commerce is that the controls and organization are different for each site. There is no standard way of building the navigation of the e‐commerce site. Most sites do not have a global navigation system and the local one may be confusing, like solving a maze. The goal of this study is to minimize users' look up time and make e‐commerce sites usable so visitors can easily and quickly access information. The objective of this study is to provide an implementation method by which an agent of the artificial intelligence (AI) user interface creates a standard navigation menu, called E‐menu, to increase the usability of e‐commerce.

Design/methodology/approach

The selected E‐menu items are based on a study of the graphical user interface (GUI) used in Windows environment and an evaluation of one hundred and two (102) e‐commerce sites. The prototype of the E‐menu system proves that a standard menu can be created by an intermediate intelligent agent, acting on behalf of the system user. Three sites out of 102 were chosen to be edited by the E‐menu server for the pilot study. This study also applies the Technology Acceptance Model (TAM) identifying components of usefulness and ease of use that predict user attitude toward the usage of the E‐menu system by conducting a Web‐based survey.

Findings

The survey result is promising and indicates that the e‐commerce users accept the idea of the E‐menu system. The E‐menu system makes it possible to create a standard navigation menu globally for e‐commerce sites. Although E‐menu is not ready for prime time, the prototype proves that a standard menu can be created by an intermediate intelligent agent, acting on behalf of the system user. These types of agents will become more popular in the internet paradigm as the number of e‐commerce sites increase and the usability of the sites decrease due to rapid deployment strategies and technological deficiencies.

Originality/value

The paper provides information on a method to increase the usability of e‐commerce sites.
