Artificial intelligence (AI) is experiencing growth and prosperity worldwide because of its convenience and other benefits. However, AI faces challenges related to consumer resistance. Thus, drawing on the user resistance theory, this study explores factors that influence consumers’ resistance to AI and suggests ways to mitigate this negative influence.

This study tested four hypotheses across four studies by conducting lab experiments. Study 1 used a questionnaire to verify the hypothesis that AI’s “substitute” image leads to consumer resistance to AI; Study 2 focused on the role of perceived threat as an underlying driver of resistance to AI. Studies 3–4 provided process evidence by the way of a measured moderator, testing whether AI with servant communication style and literal language style is resisted less.

This study showed that AI’s “substitute” image increased users' resistance to AI. This occurs because the substitute image increases consumers’ perceived threat. The study also found that using servant communication and literal language styles in the interaction between AI and consumers can mitigate the negative effects of AI-substituted images.

This study reveals the mechanism of action between AI image and consumers’ resistance and sheds light on how to choose appropriate image and expression styles for AI products, which is important for lowering consumer resistance to AI.

This study aims to investigate the properties of mortar made from a bottom ash substitute as a sustainable construction material. It is believed that the use of cement in concrete construction contributes to the release of carbon dioxide into the atmosphere, which has been a consistent increase in recent years. The utilization of bottom ash waste is expected to reduce pollution associated with cement production.

Bottom ash is used as replacement materials for cement and fine aggregate in the manufacture of mortar. Bottom ash substituted for cement of 10%, 20% and 30% of the total weight of the binder, whereas bottom ash substituted for the fine aggregate of 30%, 40% and 50% of the total weight of the sand. Binder properties were determined using scanning electron microscopy and energy dispersive X-ray. Meanwhile, the fresh properties (slump flow) and hardened properties were determined (compressive strength and mass density). In the hardened properties test, two types of curing were used: water and sealed curing.

The compressive strength of mortar decreased as the amount of bottom ash as cement replacement. However, the compressive strength increased when bottom ash was used as aggregate replacement. Additionally, bottom ash was sufficient as a substitute for fine aggregate than as a substitute for cement.

This research presents test results that are more straightforward to apply in the construction site.

The purpose of this study is to explore the substitute scarcity appeals (unit scarcity or option scarcity) effect on experiential gift’s purchase intention, based on difference in gift attribute (hedonic or utilitarian gift) and difference in the types of givers (close or distant giver), which is a new consideration.

This study was conducted with two experiments and examined four hypotheses in total. These hypotheses were examined using a 2 × 2 between-subjects designs, and a two-factorial covariance analysis was conducted.

Empirical results show that unit scarcity produces greater purchase intention than the option scarcity of close givers. For hedonic gifts, unit scarcity produced greater purchase intention than the option scarcity.

The originality of this study is to explore the substitute scarcity appeals effect on experiential gift’s purchase intention based on different types of givers and different types of gifts. The result serves as the gift marketing strategy of online platform operators and the future reference for marketers to create more value and purchase intention.

The purpose of this study is to evaluate the quality and sensory properties of cookies produced from wheat flour using avocado puree as fat substitute.

Cookies were produced from wheat flour using avocado puree as fat substitute in ratio 0%, 25%, 50%, 75% and 100%, respectively. The formulation of margarine and avocado puree blends was done by using D-Optimal Mixture Design. In all, 20 samples were produced from each substitution level and analyses were done in triplicates to obtain mean values using standard methods. Means were separated by Duncan’s multiple range test, and significances were accepted at less than 5% confidence level (p < 0.05). Proximate and functional analyses were conducted on the flour samples, while cookie samples were subjected to proximate and sensory analyses.

The results of this study revealed that the values of loose bulk density, packed bulk density, oil absorption density, water absorption capacity, swelling power, solubility and dispersibility of the flours at p < 0.05 are 0.3–0.4 g/ml, 0.5–0.7 g/ml, 16.9%–94.0%, 39.7%–80.6%, 461.2%–618.2%, 6.0%–29.8% and 69.0%–82.8%, respectively. The moisture, protein, fat, total dietary fiber, total ash and carbohydrate contents of the cookies at p < 0.05 are 3.6%–16.7%, 6.5%–9.9%, 2.5%–19.2%, 1.7%–1.9%, 1.1%–3.0% and 65.0%–70.7%, respectively. The taste, color, crispiness, texture and overall acceptability of the cookies at p < 0.05 are 7.4–7.8, 6.9–7.5, 7.2–7.9, 7.3–7.7 and 7.4–8.3, respectively. The sensory scores showed that panelists preferred the taste, crispiness and texture of the cookies produced from wheat flour using avocado puree as fat substitute at varying proportion. The sensory characteristics of sample WF⁴ (100% avocado puree) were rated overall best in all the parameters tested followed by sample WF³ (75% avocado puree). Hence, this study established the possibility of producing cookies from wheat flour using avocado puree as fat substitute without a negative impact on the sensory characteristics and the consumers’ acceptability.

The cookies produced from this study are not meant for vegetarians because eggs were added in the formulations and recipes but could be valuable to ovo-vegetarians that may take food with eggs without restriction. The major challenge of this study was that avocados are very expensive in much of the world, so this is only suitable and viable where there is an excess of the fruit.

This study examined the use of avocado puree as fat substitute in cookie production. Effects of avocado puree on proximate composition and functionality of cookies produced from wheat flour were also determined. This approach was novel, and it will encourage the use of avocado for value-added in industrial food production.

The purpose of this study is to examine whether voluntary disclosure (VD) and corporate governance (CG) are substitutes or complements to each other in improving firms’ value in a non-Anglo-Saxon setting, namely, France.

This study uses a sample of 990 listed firms in France from 2010 to 2020 to test the theoretical predictions. A random effect regression and two-stage least squares estimators are used to test the relationships. The results are largely robust across a number of econometric models that take into account diverse kinds of endogeneities.

This study reveals that VD and CG are positively associated with firm value. The finding also indicates that VD and CG work together as substitutes rather than as complements. Furthermore, the author’s evidence suggests that ownership structure and CEO characteristics are substitutive with VD in their effect on firm value. This evidence is consistent with the view that VD can add value to the firm but only under a number of conditions.

The results shed further light on how a firm could improve its value among stakeholders by designing VD and CG practices effectively. Specifically, as VD generally acts as a substitute to CG, to accomplish their optimal economic outcomes, firms need to be discerning in executing VD and governance practices. In addition, firms have strategic flexibility in constructing VD and governance practices contingent on their own settings. Policymakers, investors and managers could use these results to examine CG and VD practices in France following the implementation of new regulations.

This study extends and contributes to the mixed or equivocal evidence of the relationships between VD, CG mechanisms and firm value. It contributes to the extant literature by first providing additional evidence, which suggests value-increasing effects of better-governed and more transparent firms. Second, this study reconciles extant disparate results by suggesting that VD can substitute CG in improving firm value. These findings have profound implications for policymakers, investors and firm’s managers.

The comment addresses the idea of substituting professional elder care with informal care provided by early retirees to save economic costs.

The comment arose from reading “How to handle gerontocracy”, scientific research and critical, analytical thinking.

While having early pensioners deliver elderly care has positive implications, substituting professional with informal care must be challenged. First, the “unused reservoir” of early pensioners might be overestimated, as they often already have care responsibilities. Second, the substitution of professional services is already happening due to staff shortages. Third, untrained caregivers might struggle to provide the needed care quality, resulting in worse health outcomes (and higher follow-up costs). Finally, there are concerns of social sustainability: because of role expectations, mainly women may take on care tasks, reinforcing social inequality. Also, the third sector might lose hours of volunteer work.

The comment appeals to a critically rethinking of the idea of substituting professional services with informal care provision and argues for differentiated and well-tailored policy measures, taking into account the complex nature of (informal) caregiving.

This paper aims to examine whether financial technology is complementing the performance of domestic financial institutions or substituting their performance in Ghana.

The paper used data from the Bank of Ghana Payment System Statistics and Time Series Data of the Bank of Ghana from 2012 to 2021, by using autoregressive distributive lags estimation technique.

The results showed that in both the long run and short run, financial technology has a significant negative impact on bank performance, indicating that fintech serves as substitutes rather than complements for Ghanaian banks. These results suggest that there must be a critical review on the interoperability policy in Ghana and that banks should take advantage of the financial technology to increase profit.

Based on the authors’ study, no empirical work has been extensively done in the Ghanaian context by examining how financial technology serves as either a complement or substitute for domestic banking institutions. This paper focuses on exploring the key definition of financial technology in Ghana and how transactions through these media are affecting or improving the performance of banks.

This study aims to investigate two newly developed (3 + 1)-dimensional Kairat-II and Kairat-X equations that illustrate relations with the differential geometry of curves and equivalence aspects.

The Painlevé analysis confirms the complete integrability of both Kairat-II and Kairat-X equations.

This study explores multiple soliton solutions for the two examined models. Moreover, the author showed that only Kairat-X give lump solutions and breather wave solutions.

The Hirota’s bilinear algorithm is used to furnish a variety of solitonic solutions with useful physical structures.

This study also furnishes a variety of numerous periodic solutions, kink solutions and singular solutions for Kairat-II equation. In addition, lump solutions and breather wave solutions were achieved from Kairat-X model.

The work formally furnishes algorithms for studying newly constructed systems that examine plasma physics, optical communications, oceans and seas and the differential geometry of curves, among others.

This paper presents an original work that presents two newly developed Painlev\'{e} integrable models with insightful findings.

The purpose of this paper is threefold. First, to explore the importance of specific work environment facets for the overall job satisfaction (JS) of primary full-time permanent teachers (PTs) and substitute/temporary teachers (STs). Second, to highlight the similarity or difference in JS patterns among PTs and STs. Third, to provide guidelines for effective evidence-based human resource management (HRM) interventions targeting to boost PTs and STs JS levels by considering: (1) the perceived importance of individual work facets for them and (2) the school's performance in providing a satisfactory work environment.

Data on overall and important JS facets (i.e. satisfaction with opportunities for self-fulfillment, work intensity/load, salary/income, leadership and collegial relations) were collected from a sample of 438 PTs and STs in Greece. Moreover, MUSA, a method that combines Multi-Criteria Decision (MCDA) and Importance-Performance Analysis (IPA), was applied to uncover the critical work environment facets of PTs and STs overall JS that call for interventions.

The findings suggest that PTs seem to value, more than STs, the transactional and economic aspects of the school environment. More precisely, on the part of PTs, self-fulfillment and salary/income are the main contributors to their JS, whilst leadership is the least important facet of JS. For STs self-fulfillment and collegial relationships are the aspects of work that contribute the most to their overall JS, whilst salary/income is the least important contributor. The study results further indicate that self-fulfillment is the strong attribute of Greek schools' work environment in boosting TJS regardless teachers' status, whilst salary/income and workload are potential threats.

It is one of the few studies that provide insights into the differing JS patterns of STs and PTs through the application of a MCDA/IPA method. Therefore, it offers evidence-based guidelines that take into consideration both the school's performance (overall and facet JS) and importance of core aspects of the work experience for STs and PTs.

The purpose of this paper is to investigate the opaque inventory information disclosure strategy for an online retailer who sells two substitutable products to customers in two selling periods.

The authors develop a two-period model where an online retailer sells two substitute products with two inventory composition structures to maximize profits. The authors investigate the optimal inventory disclosure decision from both ex post and ex ante perspectives. Sensitivity analysis is performed to investigate the effects that discount rate, transaction cost and the probability of agreeable inventory situation have on the equilibrium disclosure outcome. The authors also consider risk-averse customers and horizontally differentiated products to highlight the robustness of our results.

The authors find that the online retailer will choose the opaque information disclosure when attempting to increase revenue and reduce the mismatch of supply and demand in both ex post and ex ante inventory information conditions. Comparing with ex post disclosure strategies, ex ante opaque disclosure is optimal in a larger price region, and the total revenues gap between opaque disclosure and complete disclosure gradually increase as discount rate, transaction cost or the probability of agreeable inventory situation decreases. Furthermore, strategic customers may tend to be risk neutral when faced with opaque inventory information in a two-period sales setting.

This current paper is the first paper to study the online retailer's inventory information disclosure strategy in two selling periods. Moreover, this paper presents the conditions under which the online retailer should share complete or opaque inventory information with customers to maximize the online retailer's total revenues.
