This paper aims to focus on establishing the bond-slip constitutive relation of mortar anchor under high loading rates by the dynamic pull-out test.

Self-made specimens were made for the dynamic pull-out test to explore the bond performance of mortar anchor, and the bond-slip constitutive relation of mortar anchor under high loading rates was established according to the analysis of test data.

During the loading process, the position of the peak bond stress was observed to translate to the free end. The bearing capacity of the mortar anchor was enhanced to some extent due to the increase of the loading rate.

The bond-slip constitutive relation of mortar anchor under high loading rates was established with the introduction of the position function and dynamic-load expanded coefficient.

The purpose of this paper is to articulate the impact of COVID-19 on marketing. It will shift from “physical first” to “digital first,” and from “selling to serving” the customers. This will impact all 4 Ps of marketing, as well as branding and innovation.

It is a conceptual paper based on literature review. The underlying construct used is transaction cost economics (TCE).

Using TCE, the paper finds that both consumers and marketers are very willing to shift to e-commerce and digital platforms which are both convenient, as well as cost-effective. Also, customer support organization will become a strategic advantage in interactive marketing.

This is an original paper written specifically for the special issue on the post-pandemic shock.

The consumption of supplementary cementitious materials (SCMs) has increased enormously in the construction industry. These SCMs are often waste materials or industrial by-products. This study aims to investigate the bond strength using reinforcing bars in Normal Strength Concrete (M20 grade) and High Strength Concrete (M40 grade), developed using SCMs and data was compared with concrete prepared with ordinary portland cement (OPC). The findings of the study will help in reducing the dependency on OPC and promote the utilization of waste materials in Construction.

In the present study, the bond behavior between the steel bars and the concrete was investigated in controlled, binary and quaternary concretes of M20 and M40 grades. Following the conventional procedures, samples were prepared and mechanical tests conducted (as per IS:2770–1 code for M20 and M40 grade concrete structures), which showed an improvement in the bond strength depending on the extent of overall calcium and silica content in these composite mixtures, and thus reflected the importance of vigilant utilization of used industrial waste in the OPC as a replacement without exceeding silica content beyond certain percentages for enhanced structural properties.

Experimental evaluation of bond behavior results showed a brittle nature for the controlled (OPC) concrete mixtures. While binary and quaternary concrete was able to resist the load-carrying capacity under large deformations and prevented the split cracking and disintegration of the concretes. Among different variations in the chemistry, for both M20 and M40 grades, the maximum bond strengths were observed for 10% Metakaolin + 10% Silica Fume + 30% Fly Ash + 50% OPC composition and this could be attributed to the fineness of the additives, better packing and enhanced calcium silicate hydrate (C-S-H).

Quaternary concrete may be a future option in place of OPC concrete. Very limited data is available related to the bond strength of quaternary concrete. Experimental analysis on quaternary concrete shows that its use in construction can reduce both construction cost and a burden on natural raw materials used to make OPC.

This study seeks to explore the idea that consumers select a particular shopping mode – i.e. bricks and mortar versus online outlet – based on their perceptions about whether a product or service is best bought from one or the other. It aims to posit that this perception is associated with the importance allocated to various shopping motivation dimensions.

Data for this study were collected using a self‐administered mail survey from 689 internet‐enabled US households. They represent a 28 percent response from 2,500 households that received the survey. Extensive non‐response analysis ruled out serious bias in the data.

The results from this empirical study suggest that different shopping motivations indeed influence perceptions of service type and shopping mode congruence differently. In addition, the results also suggest that services are more likely to be associated with the online shopping mode, whereas more tangible products are likely to be associated with bricks and mortar stores.

The findings have significant implications for services retail managers of both bricks and mortar and online service outlets in the areas of segmentations, targeting, and retail mix strategies. Apparently, consumers also tend to group related services or products into homogeneous shopping baskets based on their perception of congruence between the product or service and the shopping mode – online versus bricks and mortar store. These findings should help a manager plan for retailing mix strategies, catering to various shopping motivation dimensions, thus enhancing consumer satisfaction. In addition, the results hold important implications in the areas of segmentation and targeting decisions.

The purpose of this paper is to examine perceptions of institutional encroachment and community responses to it. Specifically, it focuses on residents’ perceived effects of hospital and university expansion and the role of place making on gentrification in core city neighborhoods. This study offers insights into the processes driving neighborhood displacement and the prospects for grassroots efforts to curb it.

Data were collected through focus groups with residents and other stakeholders in working class, minority neighborhoods which were identified as being in the early stages of gentrification. Nine focus groups were held across three neighborhoods experiencing institutional encroachment. The analysis was guided by standpoint theory, which focuses on amplifying the voices of groups traditionally disenfranchized from urban planning and policy processes.

The findings suggest that residents perceived institutional encroachment as relatively unabated and unresponsive to grassroots concerns. This led to heightened concerns about residential displacement and concomitant changes in the neighborhoods’ built and social environments. Experiences with encroachment also increased residents’ calls for greater grassroots control of development.

This analysis illuminates how gentrification and displacement results from both physical redevelopment activities of anchor institutions and their decisions related to place making. The conclusions highlight the importance of empowering disenfranchized groups in the place-making process to minimize negative externalities at the neighborhood level.

The transition to omnichannel retail is the recognized future of retail, which uses digital technologies (e.g. augmented reality shopping assistants) to enhance the customer shopping experience. However, retailers struggle with the implementation of such technologies in brick-and-mortar stores. Against this background, the present study investigates the impact of a smartphone-based augmented reality shopping assistant application, which uses personalized recommendations and explainable artificial intelligence features on customer shopping experiences.

The authors follow a design science research approach to develop a shopping assistant application artifact, evaluated by means of an online experiment (n = 252), providing both qualitative and quantitative data.

Results indicate a positive impact of the augmented reality shopping assistant application on customers' perception of brick-and-mortar shopping experiences. Based on the empirical insights this study also identifies possible improvements of the artifact.

This study's assessment is limited to an online evaluation approach. Therefore, future studies should test actual usage of the technology in brick-and-mortar stores. Contrary to the suggestions of established theories (i.e. technology acceptance model, uses and gratification theory), this study shows that an increase of shopping experience does not always convert into an increase in the intention to purchase or to visit a brick-and-mortar store. Additionally, this study provides novel design principles and ideas for crafting augmented reality shopping assistant applications that can be used by future researchers to create advanced versions of such applications.

This paper demonstrates that a shopping assistant artifact provides a good opportunity to enhance users' shopping experience on their path-to-purchase, as it can support customers by providing rich information (e.g. explainable recommendations) for decision-making along the customer shopping journey.

This paper shows that smartphone-based augmented reality shopping assistant applications have the potential to increase the competitive power of brick-and-mortar retailers.

The purpose of the paper is to examine the benefits delivered to traditional retailers from using shopping portals as their entry mechanism to the online trading environment. The paper also aims to highlight the possible drawbacks inherent in such an approach.

A case study approach was used with an online portal, combining documentary analysis and semi‐structured interviews, using a team‐based interviewing approach. This facilitated the development of a multi‐layered picture of the organisation.

Using a shopping portal delivers several benefits to traditional retailers in terms of marketing synergies, site traffic generation, access to web site management and fulfilment services, and the ability to offer customers a multi‐channel retailing experience. Drawbacks may include partner interdependence and turnover, restricted organisational learning and restricted delivery capabilities.

Highlighting the benefits and drawbacks of shopping portals generates guidelines that traditional retailers can consider to help them decide whether such portals are the right choice for their individual firm or not.

This paper expands the literature on the phenomenon of the online portal by demonstrating its potential as a mechanism for traditional retailers to engage in electronic retailing.

With the booming of live commerce, sellers provide products through not only their traditional channels but also the anchors who show products by live broadcast, forming a live commerce supply chain. In fact, such selling mode generates two effects: the live broadcast service of the anchor affects the return rate of products sold live (live commerce effect) and related products of the manufacturer sold via its own channel (live commerce spillover effect). In this paper, the authors investigate the impacts of both live commerce and live commerce spillover effect on the price decisions as well as the anchor's service effort.

The authors establish a live commerce supply chain model where the manufacturer sells related products directly and by the anchor with a wholesale price contract. The manufacturer decides the price of product sold directly based on the anchor's broadcast effort since there exists the live commerce spillover effects. Backward induction is used to solve the Stackelberg game between the manufacturer and the anchor.

The results show that (1) the existence of the live commerce spillover effect brings more profit to the manufacturer while it reduces the anchor's profit. Moreover, the total profit of the live commerce supply chain first decreases and then increases as the intensity of the live commerce spillover effect improves. (2) The pricing of products sold directly by the manufacturer and sold through the anchor is nonmonotonic with respect to the live commerce spillover effect. (3) The increase in return cost always leads to an increase in the profit of the anchor, whether it is borne by the anchor or by the consumer. (4) If the baseline return probability is high, the anchor should increase her effort, thus securing more profit. However, the spillover effect of live commerce and the horizontal differences between products will discourage the anchor from increasing the live streaming service level.

The study proposes the live commerce supply chain model where the anchor balances the cost and benefit of her live broadcast effort, which lowers the consumers expected return possibility. In addition the live commerce spillover effect is introduced, reducing the expected return rate for the related products without live broadcast (in the direct channel). With the inter-influence of live commerce, the price competition between the live anchor and the manufacturer becomes more complex. By solving the typical live commerce game model, managerial insights are given for the decision makers among the live commerce supply chain.
