High-ductility cementitious composites (HDCC) have an excellent crack controlled capacity and corrosion resistance capacity, which has a promising application in structure engineering under harsh environment. The purpose of this study is to explore the corrosion mechanism of steel bar in HDCC.

Intact and the pre-cracked HDCC specimens under the coupled action of different dry–wet cycles and chloride attack were designed, and intact normal concrete (NC) was also considered for comparison. Corrosion behavior of a steel bar embedded in HDCC was analyzed by an electrochemical method, a chloride permeability test and X-ray computed tomography.

Steel corrosion probability is related to the chloride permeability of the HDCC cover, and the chloride permeability resistance of HDCC is better than that of NC. Besides, crack is the key factor affecting the corrosion of steel bars, and the HDCC with narrower cracks have a lower corrosion rate. Slight pitting occurs at the crack tips. In addition, the self-healing products and corrosion products fill up the cracks in HDCC, preventing the external aggressive ions from entering and thereby decreasing the steel corrosion rate.

HDCC has a superior corrosion resistance than that of NC, effects of variable crack width on corrosion behavior of steel bar in HDCC under the coupled actions of different dry–wet cycles and chloride attack are investigated, which can provide the guide for the design application of HDCC material in structure engineering exposed to marine environment.

Using data from Vietnam to reveal which factors affected the impressive growth of Vietnam's e-commerce during the COVID-19 pandemic.

Drawing on the Stimulus–Organism–Response (S-O-R) framework, the study proposed a conceptual model in which the influence of COVID-19 information overload (IO) on online purchase intention (OPI) was discovered. The authors were also interested in examining the moderator roles of self-construal (SC), perceived ease of use (PEOU) and perceived usefulness (PU) in inducing the intention to make an online purchase.

Perceived threat (PT) and cyberchondria (C) played full mediation roles in the impact of IO on OPI. Moreover, PT was found to be a partial mediator of the relationship between IO and C. Furthermore, interdependent self-construal (IntSC) positively moderated the positive effect of IO on PT. Finally, PU and PEOU showed significant moderated moderation effects, in which PU moderated the effects of PT and C on OPI, whereas PU itself was moderated by PEOU.

Understanding the positive effects of IO, C and PT on OPI can be useful for marketers. In addition, managers should improve the ease-of-use and usefulness of online stores/platforms to attract more consumers to online channels.

Marketers and managers should learn more about how to take advantage of IO, PT and C. For instance, to sell medical supplements, marketer should push up related-health information such as obesity, diabetics, to make consumers perceive a threat to their health and search for ways to improve their health condition. This is the time when advertisements for medical supplements bring into play. This method can be applied in many different fields. The key is that marketers should find out what is the threat that their targeted customers can perceive and then spread out a huge amount of relevant information.

The government should control infodemic and guide people to obtain official information. This helps to restrain the PT and C, which seriously harm people's health and affect their behaviors, such as making unusual or panicked purchases. This study also suggests a considerable concern that residents of Asian cultures, where IntSC is dominant, may perceive threat more than residents of Western cultures.

Limited research addresses the relationship between PEOU and PU when they act as moderators. Current research not only explains the moderation effect of PU under the influence of PEOU but also suggests that PEOU may be more important than PU in emerging markets due to customers' inexperience in online markets or channels. It also explores the factors that influenced OPI in Vietnam during the COVID-19 outbreak and contributes to the scientific literature on Vietnam, especially in terms of discovering the tendency of SC, which has not been mentioned before in research about Vietnamese.

The purpose of this paper is to examine the impact of consumers’ attitudes towards organic food on online impulse buying behaviour as well as the moderating effect of three website features (visual, information and navigation design) on this relationship.

Survey data were collected via an online survey using social media platforms. A total of 653 online questionnaires were collected (response rate = 72.5 per cent) and analysed by applying exploratory and confirmatory factor analyses. The proposed hypotheses were tested through structural equation modelling.

Social media forums, ratings and reviews shape Chinese consumers’ attitudes towards organic food and positively influence their online impulse buying in this market. Website features are critical for disseminating information on organic food. Informative webpages featuring product quality and certification have a greater moderating effect on purchase. Information cues such as nutritional content; production and processing methods, and environmentally friendliness also influence consumers’ attitudes and thus impulse buying decisions.

Marketers should reconsider their tactics for dealing with modern consumers, as webpages should be user-friendly and visually appealing with a social learning mechanism to drive organic food consumption.

This study bridges a gap in the literature on social commerce initiatives for developing consumers’ attitudes towards organic food and online impulse buying. Further, it proposes measures that can enhance organic consumption and contributes to the literature on the importance of social factors, resulting in enhanced knowledge on the online impulse buying of organic food.

The purpose of this paper is to study fabrication of optical‐PCBs on panel scale boards in a conventional modern PCB process environment. It evaluates impacts on board design and manufacturing with the developed optical board verifiers outlining challenges and requirements for manufacturing low‐loss waveguide structures and optical building blocks. The study aims to expand the current knowledge in the field by adding results obtained by utilizing industrial production infrastructure and developed scalable manufacturing processes to fabricate optical‐PCBs and board assemblies in high‐volumes and low‐cost manner.

Impacts on board design and manufacturing were studied with the developed optical technology verifiers. One verifier is optical‐PCB with embedded waveguides, integrated i/o couplers and optical vias. Another verifier is large size PCB with optical layer. A system‐level optical board assembly with 12.5 Gb/s Tx/Rx devices on surface mounted ball grid array (BGA) modules is designed for optical link analysis. Fabricated optical structures on verifiers are evaluated of their physical characteristics utilizing optical, SEM, LSCM analysis methods. Performance testing is conducted using standard optical transmission measurement methods and equipment.

The paper provides empirical results about fabrication of multimode optical waveguides with conventional PCB process equipment. Results suggest that current coating and imaging equipments are capable of producing optical waveguide patterns with high resolution and size accuracy. However, fabricators would require larger process window and defect tolerance for processing optical materials to obtain low‐loss waveguides with sufficient yields.

Because of the limited amount of design variants in production verifiers evaluated in this paper, some impacts like effect of base material, board construction, optical layer location and beam coupling solution were not evaluated. Likewise, impacts on long‐term stability and cost were not addressed. These factors however require further investigation to address technical feasibility of optical PCBs technology prior commercial high volume production.

The paper includes implications for the development of a fabrication methods and testing procedures for optical polymer waveguide layers on PCBs.

This paper fulfils need to provide results on design, fabrication and characterization of optical PCBs and backplanes from industrial fabricator's perspective. The paper provides input for end‐user and developers to evaluate technical performance, robustness, and maturity of building blocks and supply chain to support polymer waveguide based technology for intra‐system optical links.

The purpose of this paper is to investigate the electronic word-of-mouth (eWOM) motivations of regulatory-focused customers with positive and negative consumption experiences.

An online survey is conducted in Beijing and Shanghai. A random sampling technique is used to collect data from 854 respondents. Two scenarios of eWOM communication – positive and negative consumption experiences – are randomly assigned to each respondent. This study employs the structural equation modeling and confirmatory factor analysis techniques. However, it uses ordinary least squares and logistic regression to analyze 137 participants in the experimental study.

Promotion-focused customers that aim for self-enhancement and obtaining social benefits are motivated to spread positive eWOM on social networking sites. However, prevention-focused customers are driven by vengeance and anxiety, revealing higher intentions to post negative eWOM on review sites. eWOM generation is subject to gender, as promotion-focused male customers spread it more than both prevention-focused and promotion-focused female customers. Moreover, platform assistance (PA) has a significant positive impact upon regulatory-focused customers and eWOM (positive vs negative) relationships.

This study provides a deeper understanding of motivational factors of eWOM communication. Specifically, in case of product or service failure, negative consumption experiences drive prevention-focused customers to generate negative eWOM. Thus, using various tactics, marketers need to shift customers from focusing on prevention to focusing on promotion. For example, redeemable free coupons can shift customer attention and generate positive eWOM.

This study provides unique insights about eWOM motivation across genders. It examines regulatory focus, positive vs negative consumption experiences and moderation of PA.

The paper aims to investigate the level of student satisfaction with campus student housing facilities (SHF) at Malaysian research universities (RUs) and the relationship between satisfaction and loyalty behaviour.

The student residential satisfaction (SRS) framework has been proposed to investigate residential satisfaction from the students' viewpoint. Questionnaires were distributed to respondents in three RUs. The data were analysed using descriptive statistics.

In general, students are satisfied with the provided SHF with the SRS index of 2.96 or 74 per cent satisfaction level and there is a significant relationship between overall satisfaction and loyalty behaviour. The results also confirmed that the proposed model is an adequate instrument to measure SRS.

The existence of quality SHF is likely to act as an effective medium to attract local and international students to enrol in Malaysian universities. Further actions should be geared towards achieving a higher score of SRS index.

This paper introduces a practical model of SRS to be applied to universities in other countries with similar climate and culture.

In response to the top-down professional development (PD) practice, this study conceptualizes lesson study (LS) as a bottom-up approach to foreign language teacher PD in the Turkish context. Relatedly, the authors seek to empower teachers so that they can engage in reflexive PD and claim voice over their practices.

An LS project including four teachers was implemented at a higher education language centre and conducted as a critical ethnographic study. Using ethnographic research qualitative data collection methods such as field notes, interviews and artefacts, the data were analysed with a thematic analytic approach.

Drawing on cultural-historical activity theory (CHAT), findings revealed that LS was a meta-activity that allowed teachers to be agents of the PD practices. More significantly, LS empowers teachers to have a situated impact on their development activities in addition to the meta-activity's impact on them.

This study is one of the few that goes beyond the reflective value of LS and gives contextual evidence of how reflexive PD can occur in LS. The reflexive relationship between the agent (participant–teachers) and the process (LS practice) provides a strong implication revealing the transformative impact of bottom-up PD activit(ies).

The purpose of this paper is to examine the factors explaining the success of Hong Kong’s Independent Commission Against Corruption (ICAC) and the challenges which it faces in maintaining that success.

Utilising a review of primary and secondary sources, a syndrome of success characteristics is developed and analysed against a backdrop of recent high-level scandals involving corruption and unethical behaviour.

The paper concludes that the institutionalisation of key structures and processes has enabled the ICAC to perform successfully to date but that the prospect of political interference may represent a significant future challenge.

Although there has been widespread attention to ICAC success factors, some important features have been neglected and little academic attention has been devoted to recent political challenges to its position.

The purpose of this paper is to examine the business-government nexus in Hong Kong as a special case, thereby contributing to a comparative examination of various significant variables affecting the study of political and economic developments in East Asia.

The paper considers the privileged position afforded to the major business groups in Hong Kong’s political system as part of the pro-Beijing United Front. It adopts a historical perspective, relying on existing literature including media reports. As the author is both an academic and a long-term pro-democracy activist, his actual experiences and extensive interviews with various important participants in Hong Kong’s business and political communities offer valuable perspectives.

In the past, the business-government nexus was perceived to be a positive factor that contributed to the territory’s economic growth. In the past decade or so, though, increasing dissatisfaction with the Hong Kong government’s performance and the widening gap between the rich and the poor have led to the emergence of a legitimacy deficit on the part of the government, resulting in rising demands for democracy which have not been met. Divisions on these issues within the local business community have posed a severe challenge to the continuation of the business-government nexus.

The author’s actual experiences and his interviews with other participants in Hong Kong’s politics provide observations of significant value. The Occupy Central campaign, which took off in the territory in 2014, demands serious consideration in terms of its political development and a key element for consideration is the response of the business-government nexus to it.
