Abstract
Purpose
This paper aims to study the frictional performance of reciprocating pair with high velocity by using hydrodynamic lubrication principle and fish scale textured piston model.
Design/methodology/approach
Based on the idea of function characteristic approximation and coordinate change, a mathematical representation model of imitating fish scale texture pit section is established. According to the principle of dynamic pressure lubrication of the textured fluid, a three-dimensional numerical model of flow field for fish scale texture is established without considering cavitation. Numerical analysis of the model carp scale texture unit by orthogonal experimental design and FLUENT software is carried out.
Findings
Effects of fish scale pit texture on friction properties for a reciprocating pair piston surface with high velocity (impact piston) are acquired. Effects of texture characterization parameters and flow rate on the surface friction performance for impact piston are found. Effects of different characteristic parameters combination of imitating fish scale texture on friction performance for impact piston surface are obtained.
Originality/value
The model is an effective tool to study the friction and wear of reciprocating pair with high velocity. The effects of fish scale textured piston pair supply a theory lead to design the reciprocating pair with better friction performance.

Abstract
Purpose
This study aims to move beyond the current understanding of corporate social responsibility (CSR) to propose the concept of just-in-time (JIT) CSR as a metaphor that reflects hospitality operators’ endeavors to expedite socially responsible measures to both internal and external organizational stakeholders during times when functional and emotional supports are urgently needed.
Design/methodology/approach
This research used a qualitative approach in two studies. Study 1 engaged a media analysis to better grasp the knowledge of the research problem at hand. Study 2 involved interviews from stakeholders to assess their emotions and perceptions of meanings of major contents discerned from the first study.
Findings
This research highlights a process in which operators’ CSR practices (e.g. for business practices, for organizational strategy and for stakeholder well-being) during the COVID-19 crisis are imbued with connotative meanings (e.g. place-as-safety, place-as-partnership and place-as-warmth) that ultimately give shape to three core outcomes (e.g. individual rejoinder, brand resonance and societal resilience).
Research limitations/implications
While JIT CSR is not an antidote for all devastations caused by COVID-19, it is posited as a needed mechanism that operators could use to ameliorate the situation and to go beyond their own stake to bring a broader array of societal benefits to humanity.
Originality/value
This research underscores how hospitality operators expedite crisis responses to the pandemic, and how their societal objectives transform the image of a place from a commercial venue into a place imbued with meaning associated with safety, partnership and warmth.

Abstract
Purpose
As the use of AI techniques becomes more prevalent in evaluation activities, researchers have suggested integrating AI and human evaluators to address potential AI aversions from applicants. This study was conducted in response to this call, utilizing a Chinese sample.
Design/methodology/approach
This study examined applicants’ responses to decisions made by a human–AI hybrid jury with varying levels of AI agency. Using a three (AI agency: low, medium and high) × 2 (outcome favorability: favorable and unfavorable) between-subjects design, we analyzed the moderated mediation relationship between machine heuristics and organizational assessment, with fairness perceptions serving as a mediator and AI agency level and outcome favorability as moderating variables.
Findings
The results revealed that positive machine heuristics enhanced fairness perception only at high AI agency levels, irrespective of outcome favorability. Negative machine heuristics impaired fairness perception at medium or high AI agency levels only in cases where participants failed the test. Machine heuristics did not directly influence participants’ assessment of the organization but could indirectly influence organization assessments through fairness perception, contingent on the composition of AI agency level and outcome favorability.
Originality/value
By having participants go through a real intelligence exam and explore their experiences, this study had theoretical and practical implications for AI evaluation.

Abstract
Purpose
This research paper aims to explore Airbnb’s online experience initiative, which has sparked a new wave of virtual tourism to improvise a large assortment of experiential activities through cyberspace. It works to answer questions pertinent to the type of virtual experiences tourists seek and how these experiences could fulfill tourist needs, thereby rendering favorable socio-mental outcomes through experiences encountered.
Design/methodology/approach
Drawing on travel experience and transformative tourism theoretical tenets, this qualitative inquiry used data collected from social media posts from virtual tourists.
Findings
Results reveal four major themes of online experiences – hedonism, attention restoration, social relatedness and self-exaltation – that encompass 12 experiential categories. They further underscore four types of transformative mechanisms pinpointing hedonic well-being, environmental-mastery well-being, social well-being and eudaimonic well-being.
Research limitations/implications
Research findings demonstrate how Airbnb exercised marketing agility during severe environmental plight; while expediting strategic initiatives that offer tourists and residents alike a means to reengage in leisure and travel activities at home. They also salvage the peer-to-peer community by turning accommodation hosts into online experience ambassadors.
Originality/value
The contribution of this inquiry lies in assessing virtual experiences and reconnecting how different cyber experiences can meet an array of tourist needs. This study further highlights the transformative virtual experience paradigm to lay the necessary theoretical foundation for future research on virtual transformative tourism. This research goes beyond the common understanding of transformative tourism that relies merely on corporeal encounters. From a practical point of view, this study brings light to a novel concept – sharing experience economy – that incorporates the nuances between sharing economy and experience economy.

Abstract
Purpose
The coronavirus (COVID-19) pandemic response is not only devastating nations and economies across the globe but it is also severely disrupting the event industry, with government and health authorities forcing many events to be postponed or cancelled. The purpose of this study is to investigate the prospective attendees’ emotional responses to cancelled events. This study draws upon grief cycle theory to articulate different layers of the grief process in the event domain of inquiry.
Design/methodology/approach
The National Collegiate Athletic Association basketball tournament was selected as the research context. Taking user-generated messages from Twitter, this study first performed content analysis to organize lexical patterns into categories and higher-order themes based on the grief cycle. It also performed social network analyses using UCINET to illustrate how different grief phases are inter-related.
Findings
Results not only point to attendees’ self-expression manifested through a continuum of denial, anger, bargaining and acceptance but they also reveal a three-layer hierarchy of grief, namely, event-related, socio-politics-related and crisis-related. The network analysis further illustrates how grief phases are tied into a complex network of grief messages.
Originality/value
This study advances the event literature by improving knowledge about attendees’ emotional responses to cancelled events. It increases our understanding of the grieving process in the aftermath of COVID-19. The proposed triple grief cycle helps advance the literature by showcasing how voices from prospective attendees represent three pillars of grief hierarchy. The findings also underscore the emotional crisis of the COVID-19 aftermath.

Abstract
Purpose
Soil nutrient management and fertilizer use by farmers are important for sustainable grain production. The authors examined the effect of an experimental agricultural extension program, the science and technology backyard, in promoting sustainable soil nutrient management in the North China Plain (NCP). The science and technology backyard integrates farmer field schools, field demonstrations, and case-to-case counselling to promote sustainable farming practices among rural smallholders.
Design/methodology/approach
The authors conducted a large-scale household survey of more than 2,000 rural smallholders. The authors used a multivariate regression analysis as the benchmark to assess the effect of the science-and-technology backyard on smallholder soil nutrient management. Furthermore, the authors used coarse exact matching (CEM) methods to control for potential bias due to self-selection and the (endogenous) switching regression approach as the main empirical analysis.
Findings
The results show that the science-and-technology backyard program increased smallholders' wheat yield by approximately 0.23 standard deviation; however, no significant increase in maize yield was observed. Regarding soil nutrient use efficiency, the authors found a significant improvement in smallholders' phosphorus and potassium use efficiencies for both wheat and maize production, and a significant improvement in nitrogen use efficiency for wheat production, but no significant improvement of nitrogen use efficiency for maize production.
Originality/value
This study evaluated a novel participatory agricultural extension model to improve soil nutrient management practices among smallholders. The integration of agronomists' scientific knowledge and smallholders' local contextual experiences could be an effective way to improve farmers' soil nutrient management. This study provides the first quantitative estimates based on rigorous impact assessment methods of this novel extension approach in rural China.

Abstract
Purpose
The purpose of this paper is to explore the expansion of agricultural production into marginal lands, also known as “wasteland,” and examine the association between political capital, household income, and using additional marginal lands for agriculture in the Xinjiang Uyghur Autonomous Region of western China.
Design/methodology/approach
The paper uses exploratory data analyses methods, including descriptive statistics, graphical analysis, econometrics and propensity score matching, and data from a 2008 survey of 342 households in Awat County of Aksu Prefecture to explore the role of political capital in an agricultural household setting.
Findings
Preliminary results suggest that wasteland usage has a positive association with income, and that household political capital, in the form of Communist Party membership or being a village cadre, correlates with wasteland usage because it improves access to irrigation water.
Originality/value
A constant topic of debate in China is the role of political capital in influencing livelihoods. The authors aim to add modest insights into this debate and provide a starting point to foster additional debates regarding the role of political capital, rural livelihoods, and natural resource usage.

Abstract
Purpose
In the evolving digital landscape, customers connect with the diversified digital marketing platforms, posing both obstacles and opportunities to consumers. In response to the changing landscape of social media and technical advances within the fashion business, the study aims to investigate the role of virtual fitting rooms in influencing consumer behaviour and purchase intentions through social media, with respect to fashion products.
Design/methodology/approach
The study used a combination of primary and secondary data, relying on secondary sources to identify research gaps and construct the conceptual framework and a survey-based approach enabled the collection of 352 responses from metropolitan cities of India like Bangalore, Chennai, Kolkata and New Delhi using snowball sampling for studying research variables. The hypothetical relationships were tested using various statistical techniques such as multiple regression analysis, measurement model assessment using confirmatory factor analysis and structural equation modeling (SEM).
Findings
The present study connects the dots between social media, virtual fitting rooms, engagement characteristics, buying intentions and consumer purchasing behaviour by manifesting a positive association with engagement metrics that correspond to the current user-behaviour pattern. As per results, virtual fitting rooms are significantly associated with effectiveness of social media. Moreover, social media as a mediator significantly amplifies the impact of virtual fitting rooms on the intents and behaviour of consumers while making purchases.
Originality/value
Research spotlights the novel findings (i.e. interactive, visual, personalized shopping moments and social capabilities features) of social media in enhancing the interaction with virtual fitting rooms, which shapes the fashion purchasing decisions.

Abstract
Purpose
This study aims to determine whether the stock holdings of equity mutual funds are informative for predicting future stock performance in the Chinese market. It is a puzzle that actively managed mutual funds underperform passive benchmarks, whereas retail investors still delegate investment decisions to the fund managers. The present study sheds light on whether mutual fund managers possess security selection skills in their top ten holdings.
Design/methodology/approach
By regression analysis and portfolio sorting, this study focuses on 830 Chinese A-share stocks in the industry research reports from the Guotai Junan Securities Company. It collects mutual fund's top ten holdings data from the Wind Financial Terminal between 2019Q1 and 2021Q1. As robustness checks, the result holds for the fixed-effect model, an additional measure of ranks in the top ten holdings, the predictability test based on the confusion matrix and two stage least square (2SLS) regression.
Findings
The authors find that the top ten holdings by equity mutual funds are informative for predicting stock performance and can provide valuable information for investors to support their decision-making.
Practical implications
The findings of this study provide insightful guidance for retail investors in making investment decisions and support the hypothesis that active fund management adds value.
Originality/value
Firstly, the authors find that the top ten holdings of Chinese mutual funds show significantly positive signals for future stock excess returns, indicating the selection skills of fund managers. Secondly, the above positive relationship exhibits a diminishing marginal effect with more funds holding this stock. Thirdly, the authors find that the predictability horizon of the number of overweighing funds is up to three quarters and then diminishes in the fourth quarter. Finally, investors have a 59% prediction accuracy for the whole stock sample and an 85% precision conditional on the predicted positive subsample to outperform the market. The authors also address the endogeneity and reverse causality issues.
