Supply chain integration (SCI) is key to implementing omni-channel retailing (OCR) strategy. In this paper, the authors explore the role of digitalization as a driver of SCI, as well the role of human capital (HC) in digitalization, using a knowledge management (KM) perspective.

An empirical study was conducted using survey research. A sample of 188 omni-channel retailers in the Chinese market was analyzed using factor analysis and structured equation modeling (SEM) to examine the hypotheses presented in the conceptual model.

This study reveals that HC is positively related to the level of a firm's digitalization in OCR, and that digitalization is positively related to the retailer's SCI. Moreover, the authors found that employees' capital has a greater impact on digitalization than managers' capital, while digitalization has a stronger driving effect on internal and customer integration.

The findings suggest that although digitalization requires retailers to accept the long-term investment challenges, it has a significant positive effect on the key of OCR strategy implementation, i.e. SCI. The findings also provide evidence for the application of KM in OCR, as this theoretical lens enriches our understanding of the phenomena of SCI in OCR and provides explanation to our results by linking digitalization and HC.

Digitalization is quantified and examined in OCR. Moreover, this study reveals the importance of HC on the implementation of digitalization and the different effects of digitalization on each dimension of SCI.

The purpose of this paper is to apply the dynamic capability view to identify relationships between human capital (HC), supply chain integration (SCI) and firm’s performance. It also examines the moderating effect of product variety (PV) on these relationships in the context of omni-channel retailing (OCR).

An empirical study was conducted based on survey research. In total, 230 retailers in China’s market adopting omni-channel strategy were surveyed to examine the hypotheses proposed in our conceptual model using statistical techniques.

This study reveals that HC has a positive impact on SCI, and the impact of employees’ capital is greater on the success of SCI than that of managers’ capital. Moreover, the results confirm that SCI facilitates the achievement of superior performance. Organization integration contributes the most to performance improvement in OCR. Additionally, this study identifies the positive moderating effect of PV on the relationship between HC and SCI, while the moderating effect is insignificant to the influence of SCI on performance.

We obtained valuable insights for both academicians and practitioners. On the one hand, this could be an early attempt as an interdisciplinary study to empirically analyze supply chain management in OCR from human resource perspective. It reveals the importance of human resource management (HRM) and the contribution of SCI to OC retailers. Therefore, this study fills current research gaps. On the other hand, this study provides several practical insights to top management: the importance of improving an individual’s competency to sustain a retailer’s dynamic capability; and the importance of strengthening the organization’s integration to better achieve effective SCI in OCR. Additionally, this study proposes future research based on its limitations.

SCI is investigated in the context of OCR from the HRM perspective. Moreover, this study reveals the importance of HRM and discusses the moderator’s effect in OCR.

The purpose of this paper is to apply resource-based theory to identify the relationships between logistics integration capability, supply chain integration (SCI), and performance in the context of omni-channel retailing (OCR).

An empirical study was conducted based on a mixed methodology that integrates survey research and focus group. In total, 243 retailers in China have been surveyed to examine the hypotheses of the proposed conceptual model, and focus group discussion has been applied to interpret the results and identify the critical concerns on the implementation of omni-channel (OC) strategy.

This study reveals that the information integration capability and organization integration capability in logistics management significantly affects SCI, while the integrated supply chain has a greater significant influence on financial performance than operational performance to OC retailers. Moreover, a firm’s characteristics can be regarded as contextual factors influencing performance in OCR.

The authors obtained valuable insights for both academics and practitioners based on the findings. On the one hand, this is an early attempt to empirically study SCI of OCR, revealing the importance of a firm’s nature in the performance. Therefore, this study fills a current research gap. On the other hand, this research provides top managers of OC retailers, particularly supply chain managers, the awareness of the importance of improving of organizational integration and human-resource management capability. Additionally, this study proposes future research based on its limitations.

SCI is investigated in the context of OCR from a logistics perspective. Moreover, this study reveals that the human-resource management and organization management are the main concerns in the implementation of OCR.

A zero-day vulnerability is a complimentary ticket to the attackers for gaining entry into the network. Thus, there is necessity to device appropriate threat detection systems and establish an innovative and safe solution that prevents unauthorised intrusions for defending various components of cybersecurity. We present a survey of recent Intrusion Detection Systems (IDS) in detecting zero-day vulnerabilities based on the following dimensions: types of cyber-attacks, datasets used and kinds of network detection systems.

Purpose: The study focuses on presenting an exhaustive review on the effectiveness of the recent IDS with respect to zero-day vulnerabilities.

Methodology: Systematic exploration was done at the IEEE, Elsevier, Springer, RAID, ESCORICS, Google Scholar, and other relevant platforms of studies published in English between 2015 and 2021 using keywords and combinations of relevant terms.

Findings: It is possible to train IDS for zero-day attacks. The existing IDS have strengths that make them capable of effective detection against zero-day attacks. However, they display certain limitations that reduce their credibility. Novel strategies like deep learning, machine learning, fuzzing technique, runtime verification technique, and Hidden Markov Models can be used to design IDS to detect malicious traffic.

Implication: This paper explored and highlighted the advantages and limitations of existing IDS enabling the selection of best possible IDS to protect the system. Moreover, the comparison between signature-based and anomaly-based IDS exemplifies that one viable approach to accurately detect the zero-day vulnerabilities would be the integration of hybrid mechanism.

Because of the advantages of high deposition efficiency and low manufacturing cost compared with other additive technologies, robotic wire arc additive manufacturing (WAAM) technology has been widely applied for fabricating medium- to large-scale metallic components. The additive manufacturing (AM) method is a relatively complex process, which involves the workpiece modeling, conversion of the model file, slicing, path planning and so on. Then the structure is formed by the accumulated weld bead. However, the poor forming accuracy of WAAM usually leads to severe dimensional deviation between the as-built and the predesigned structures. This paper aims to propose a visual sensing technology and deep learning–assisted WAAM method for fabricating metallic structure, to simplify the complex WAAM process and improve the forming accuracy.

Instead of slicing of the workpiece modeling and generating all the welding torch paths in advance of the fabricating process, this method is carried out by adding the feature point regression branch into the Yolov5 algorithm, to detect the feature point from the images of the as-built structure. The coordinates of the feature points of each deposition layer can be calculated automatically. Then the welding torch trajectory for the next deposition layer is generated based on the position of feature point.

The mean average precision score of modified YOLOv5 detector is 99.5%. Two types of overhanging structures have been fabricated by the proposed method. The center contour error between the actual and theoretical is 0.56 and 0.27 mm in width direction, and 0.43 and 0.23 mm in height direction, respectively.

The fabrication of circular overhanging structures without using the complicate slicing strategy, turning table or other extra support verified the possibility of the robotic WAAM system with deep learning technology.

The 2019 novel coronavirus (COVID-19) outbreak is projected to have adverse consequences on the global tourism and hospitality industry. This paper aims to examine how the outbreak may alter Chinese tourists’ lifestyle choices, travel behaviour and tourism preferences in the short and long term.

This paper is based on the synthesis of news broadcasted by several media outlets to be supported by an overview of the related literature on tourism marketing, tourism management and tourist behaviour. The authors’ experiences investigating trends in tourism and hospitality at the local and international level have also contributed to the study.

This paper predicts that COVID-19 will likely affect Chinese travellers’ consumption patterns, such as the growing popularity of free and independent travel, luxury trips and health and wellness tourism. New forms of tourism including slow tourism and smart tourism may also drive future tourism activities. Such changes are likely to force businesses to reconsider their service designs and distribution channels.

While Chinese and other potential visitors rethink how they travel, professionals, too, should reflect upon how to bring positive or negative changes to the tourism industry following this pandemic. Subsequent research should also consider how to mitigate the effects of similar public health crises in the future.

Recommendations for industry practitioners and policymakers focus on tailoring travel arrangements to tourists’ backgrounds. The suggestions may help to alleviate outbreak-related stress, offer travellers newly enriching experiences and partially mitigate the effects of COVID-19 on the tourism and hospitality industry. These recommendations can also apply more broadly to global tourist markets.

The COVID-19 outbreak has already brought significant impacts to nearly every society and industry. Tourism scholars and practitioners should carefully consider this tragedy and how it may inform industry and social practices. This and other public health crises represent sterling opportunities to view the industry holistically in terms of its effects on the environment, climate and travellers themselves.

This paper presumably represents a frontier study, critically examining the possible impacts of COVID-19 on Chinese travellers’ consumption patterns and how the tourism and hospitality industry may respond to such changes in the future.

The purpose of this paper is to conduct a comprehensive study on building, fire and evacuation, so as to effectively improve the efficiency of building fire evacuation and the management level of fire evacuation site. Make up for the difficulties of BIM technology in effectively connecting building information and fire data.

First, this paper establishes a fire model and an evacuation model based on BIM information. Then, the safety index (SI) is introduced as a comprehensive index, and the IRI is established by integrating the SI function to evaluate the safety of evacuation routes. Based on these two indices, the IRI-based fire evacuation model is established.

This study offers an Improved Risk Index (IRI)-based fire evacuation model, which may achieve effective evacuation in fire scenes. And the model is verified by taking the fire evacuation of a shopping center building as an example.

This paper proposes a fire evacuation principle based on IRI, so that the relevant personnel can comprehensively consider the fire factors and evacuation factors to achieve the optimization of building design, thereby improving the fire safety of buildings.

This paper aims at building a discharge model for the power cable bellows based on plasma energy deposition and analyzing the discharge ablation problem.

Aiming at the multiphysical mechanism of the discharge ablation process, a multiphysical field model based on plasma energy deposition is established to analyze the discharge characteristics of the power cable bellows. The electrostatic field, plasma characteristics, energy deposition and temperature field are analyzed. The discharge experiment is also carried out for result validation.

The physical mechanism of the bellows ablative effect caused by partial discharge is studied. The results show that the electric field intensity between the aluminum sheath and the buffer layer easily exceeds the pressure resistance value of air breakdown. On the plasma surface of the buffer layer, the electron density is about 4 × 1,019/m³, and the average temperature of electrons is about 3.5 eV. The energy deposition analysis using the Monte Carlo method shows that the electron range in the plasma is very short. The release will complete within 10 nm, and it only takes 0.1 s to increase the maximum temperature of the buffer layer to more than 1,000 K, thus causing various thermal effects.

Its physical process involves the distortion of electric field, formation of plasma, energy deposition of electrons, and abrupt change of temperature field.

The purpose of this paper is to concern the community festival of a Jing minority village in the China–Vietnam border area. Since it was designated as a national-level Intangible Cultural Heritage in 2006, the festival has undergone many changes. The festival has steadily expanded and evolved, assuming characteristics of globalization. How is the globalized character of the Wanwei festival manifested? What are the forces behind the elevation of this local festival onto the register of national events and how did it turn into an event organized by the township?

The paper is based on the results of the author’s research on the culture of Kinh people in Wanwei from 2000 to the present. From the anthropological approach, the author mainly uses method of participant observation and in-depth interviews. The author has observed the Wanwei communal festival from 2000 to the present, interviewing about 40 villagers in Wanwei in depth, they can be leaders, intellectuals, civil servants, officials or working people.

The paper is a case study of the new aspect of globalization of a village festival. The author argues that globalization can lead to a spread of global flows but in this process of globalization, villagers also want to define the local identity, they reinvent the tradition, rewrite history, create new nuances for the gods with many different purposes. Practicing the current Wanwei village festival is a vivid example of globalization from below and the politics of tradition.

The paper adds a theoretical dimension to current globalization research. The paper also points out the political, economic and social dynamics that govern the transformation of a village festival in particular and the village culture in general in the border areas. The paper is a testament to the dynamism and flexibility of villagers when participating in the current globalization process.
