Abstract
Purpose
To prove the effectiveness of the proposed design method, this study aims to propose the Fisher equation and temperature cooling fins that control high-speed aerospace vehicles.
Design/methodology/approach
A new approach whereby the control of aerospace vehicles can be achieved by fuzzy controller and appropriate Navier–Stokes equations in this article. The design of the controller based on models of Navier–Stokes equations simplified complex mathematical simulations and approximations.
Findings
If the fuzzy controller cannot stabilize the system, the Navier–Stokes fuzzy function is injected into the system as a controller tool, and the system is asymptotically stabilized by adjusting the fuzzy parameters.
Originality/value
The simulation results show that if the tuning frequency is high enough, the fuzzy controller and fuzzy observer can create chaotic movements by adjusting the dither amplitude appropriately. The demonstration of the Fisher equation and the temperature-cooled fin control problem for high-speed aerospace vehicles has displayed the benefits of combining fuzzy control with the Navier–Stokes equation.

Abstract
Purpose
This study aims to examine the effects of coworker incivility on employees' behaviors using a moderated mediation model that conceptualizes coworker exchange (CWX) as a mediator and servant leadership as a moderator.
Design/methodology/approach
The data were collected using a multi-temporal research design. The hypotheses were tested on a sample of 1,272 participants using confirmatory factor analysis (CFA), hierarchical regression analysis and moderated path analysis. In addition, supervisor incivility was added as a control variable to partial out the potential influence on employees' behaviors.
Findings
The results of CFA ensured that all measures had discriminant and convergent validity. In addition, the results of hierarchical regression analysis and moderated path analysis indicated that CWX mediates the relationship between coworker incivility and employees' behaviors. Furthermore, servant leadership exacerbates the negative relationship between coworker incivility and CWX.
Practical implications
Leaders and practitioners should invest in communication training programs for developing employees' communication skills to avoid incivility. In addition to viewing incivility as inappropriate behavior, leaders and practitioners should understand the meaning beyond those incivilities.
Originality/value
This study utilized incivility spiral theory to examine how coworker incivility affects employees' behaviors. The mediated path analysis found that CWX mediates the relationship between these variables, which has been ignored by previous research. Furthermore, this study introduced servant leadership as a moderator to account for the “when” in incivility spiral theory, i.e. what kind of social context facilitates or inhibits the influence of coworker incivility on CWX.

Abstract
Purpose
Based on the job demands-resources model, the present study proposes viewing abusive supervision as one type of job demand causing employees' emotional exhaustion, which results in psychological withdrawal behavior. In addition, job crafting can be viewed as a means to acquire job resources, and it buffers the influence of abusive supervision on employees' emotional exhaustion. Moreover, the present study also proposes the moderating effect of job crafting on abusive supervision and psychological withdrawal behavior will be mediated by emotional exhaustion.
Design/methodology/approach
Considering the issue of common method variance, data were not only collected in a multi-temporal research design but also tested by Harman's one-factor test. In addition, a series of confirmatory factor analyses was conducted to ensure the discriminant validity of measures. The moderated mediation hypotheses were tested on a sample of 267 participants.
Findings
The process model analysis showed that emotional exhaustion partially mediates the relationship between abusive supervision and psychological withdrawal behavior. Moreover, job crafting buffers the detrimental effect of abusive supervision on emotional exhaustion, and the less exhausted employees exhibit less psychological withdrawal behavior than those exhausted.
Originality/value
This study proposed a moderated mediation model to examine how and when abusive supervision leads to more employees' psychological withdrawal behaviors, and found that emotional exhaustion is one potential mechanism and job crafting is one potential moderator. Specifically, it was revealed that employees view abusive supervision as a kind of social and organizational aspect of job demands which will exacerbate emotional exhaustion, and, in turn, lead to more psychological withdrawal behavior. However, when employees view themselves as job crafter, they can adopt various job crafting behaviors to decrease the emotional exhaustion, and thus less psychological withdrawal behavior.

Abstract
Purpose
The purpose of this paper is to attempt to unlock how and why abusive supervision influences employees’ day-to-day behaviors. Thus, the present study proposes that employees who are continuously faced with a supervisor’s hostile verbal and nonverbal behavior might obstruct their willingness to exhibit two different kinds of extra-role behaviors [i.e. organizational citizenship behavior (OCB) and voice] because sustained abusive behavior might hinder employees from their tasks and result in disengagement. Abused employees are more likely to disengage from their current tasks, and this is likely to in turn result in lower OCB and voice.
Design/methodology/approach
The data were collected from a Taiwan mid-sized high-tech manufacturing company. The present study adopted a within-person approach (a daily-basis research design) and collected data from 60 front-line employees over 10 working days. Although all variables were self-rated, common method variance is minor. Confirmatory factor analysis (CFA) was conducted to ensure discriminant and convergent validity, and hierarchical linear modeling (HLM) was used to test the hypotheses.
Findings
The results of CFA ensure the measures have discriminant and convergent validity, while the results of HLM analysis showed that work engagement fully mediates the negative relationship between abusive supervision and the two kinds of extra-role behaviors. The bootstrapping results also support the full mediation effect of work engagement.
Originality/value
The present study used the job demands-resources model to examine how abusive supervision influences employees’ OCB and voice and found that work engagement is one possible mechanism between these two types of extra-role behavior. Specifically, a daily research design discovered that in a given working day, once a leader exhibits abusive supervision behavior, compared with any given day without abusive behaviors, employees will find it difficult to focus on their current tasks (i.e. through exhibiting decreased work engagement), which will in turn influence their willingness to exhibit OCB and voice on that particular day. Thus, both researchers and managers should focus on the daily interactions between leaders and employees because it is impossible to achieve organization success in one day, but rather such success is the aggregate result of both leaders’ and employees’ daily efforts.

Abstract
Purpose
The vast majority of research on traditional leadership focuses on effective and positive leadership behavior. However, scholars have begun to pay attention to the impact of negative leadership behavior on employees and the organization. Hence, the main purpose is to examine the effects of abusive supervision. While the literature does not examine the time future orientation of the effects of abusive supervision, the purpose of this paper is to fill up this gap and examine the moderating role of future orientation.
Design/methodology/approach
A total of 584 valid questionnaires were collected from respondents aged between 21 and 30 years old and analyzed using the hierarchical regression and structural equation modeling method.
Findings
The main results show that abusive supervision positively affects counterproductive work behavior and future orientation positively moderates both the relationship between abusive supervision and originality behavior and the relationship between abusive supervision and organizational citizenship behavior (OCB).
Originality/value
This study demonstrates the moderating roles of future orientation in the effects of abusive supervision, and thus deepens the understanding of the moderating effect. It departs from the prior works and presents a more detailed examination examines the distinct dimensions of personality traits. It makes three main theoretical contributions. First, it introduces uncertainty management theory as a means to interpret the effects of abusive supervision. Second, it contributes to the literature on abusive supervision. Third, it does not lead to discovery as an OCB and originality, conclusions which differ from the results suggested in past literature.

Abstract
Purpose
In a context where retail stores are closing down and high streets are declining, the purpose of this paper is to analyse on-site shopping by tourists. This work identifies the drivers that lead tourists to use digital information sources at the beginning of the shopping process. Understanding these drivers can help destination managers and retailers encourage tourists to shop.
Design/methodology/approach
A personal survey was conducted in a Spanish city noted for its shopping facilities (Logroño), using a sample of 430 tourists with purchase intention. The survey was designed based on the extended unified theory of acceptance and use of technology (UTAUT2) model. A multivariate analysis, based on structural equation modelling, was carried out using partial least squares (PLS), based on variance.
Findings
The study’s finding is that performance expectancy, effort expectancy, social influence, facilitating conditions and habit influence intention to use digital sources of information to make purchases in a destination. Tourists prioritise utilitarian over hedonic motivations in the intention to use digital sources of information in tourist shopping.
Originality/value
It has been recognised that tourists are the perfect target to revitalise on-site shopping and, therefore, destinations must provide attractive shopping experiences from the outset. Prior to purchase, the search for available information is the first stage of the tourist shopping journey. Although many studies have analysed tourist shopping behaviour, none have focused, using the UTAUT2, on the digital information sources tourists consult pre-purchase. This research develops understanding of tourist shopping behaviour in this new technological context. This can help retailers/destinations provide better services and optimise the shopper's experience from the first stage of the process.
研究目的
零售商店陸續倒閉,商業街的經營業務逐漸式微;本文旨在分析遊客在這背景下的現場購物活動。本文擬確定遊客在購物過程的初期驅使他們使用數位資訊來源的誘因;了解這些誘因,將有助目的地管理經理和零售商推動遊客購物活動。
研究設計/方法/理念
研究人員在一個以購物設施馳名的西班牙城市(洛格羅尼奧) 進行個人調查,樣本為430名有意購物的遊客。調查是以整合性科技接受使用理論的延伸模型(UTAUT2)為基礎而設計的。研究人員使用以方差為基礎的偏最小平方,來進行以結構方程模型為基礎的多變數分析。
研究結果
績效期望、付出期望、社群影響、促成條件和習慣均影響遊客為目的地購物而使用數位資訊來源的意慾。而就這意慾而言,功利動機在優先次序上比享樂動機佔更高的位置。
原創性/價值
我們承認,要使現場購物得以復甦,遊客是最適當的目標。因此,旅遊目的地必須從一開始就要給遊客提供愉快的購物體驗。遊客購物前、尋找有關的購物資訊便是這個旅遊購物旅程的第一個階段。分析遊客購物行為的研究為數不少,唯使用第2代整合型科技接受理論(UTAUT2) 、重點探討遊客購物前使用數位資訊來源來尋找資訊的研究則從未見過。本研究讓我們更深入了解遊客在這個新技術背景下的購物行為,這有助零售商/目的地經營者為遊客提供更佳的服務、及優化遊客從購物過程首階段開始的購物體驗。

Abstract
This chapter examines the role of heritage as a means of empowering destination communities and providing deeper and more meaningful encounters between tourists and their destination, which contributes to the notion of Destination Conscience by highlighting more sustainable and humane ways of ‘doing’ tourism and opening places up to greater community involvement and access by visitors. This includes heritage concepts such as Indigenous communities, local spirituality and religious traditions, public archaeology and ordinary heritage, and how these translate into deeper engagement between residents and tourists, community empowerment and a more creative and holistic tourist experiences. Conceptually, this chapter highlights notions of empowerment, tourists' experiences and Destination Conscience.

Abstract
Purpose
Food choices profoundly affect one's dietary, nutritional and health outcomes. Using alcoholic beverages as a case study, the authors assess the potential of genetic data in predicting consumers' food choices combined with conventional socio-demographic data.
Design/methodology/approach
A discrete choice experiment was conducted to elicit the underlying preferences of 484 participants from seven provinces in China. By linking three types of data (—data from the choice experiment, socio-demographic information and individual genotyping data) of the participants, the authors employed four machine learning-based classification (MLC) models to assess the performance of genetic information in predicting individuals' food choices.
Findings
The authors found that the XGBoost algorithm incorporating both genetic and socio-demographic data achieves the highest prediction accuracy (77.36%), significantly outperforming those using only socio-demographic data (permutation test p-value = 0.033). Polygenic scores of several behavioral traits (e.g. depression and height) and genetic variants associated with bitter taste perceptions (e.g. TAS2R5 rs2227264 and TAS2R38 rs713598) offer contributions comparable to that of standard socio-demographic factors (e.g. gender, age and income).
Originality/value
This study is among the first in the economic literature to empirically demonstrate genetic factors' important role in predicting consumer behavior. The findings contribute fresh insights to the realm of random utility theory and warrant further consumer behavior studies integrating genetic data to facilitate developments in precision nutrition and precision marketing.

Abstract
Purpose
This paper aims to explore what environmental justice (EJ) can offer to sport management research and highlights the urgency for sport management scholars interested in environmental and ecological issues to engage with EJ as an important research agenda.
Design/methodology/approach
This paper is primarily a position and conceptual paper. Drawing from multidisciplinary literature (e.g. critical human geography, environmental sociology, Indigenous studies and postcolonial studies), it provides an overview of the major conceptualizations of EJ and discusses important premises for sport management researchers to engage with EJ topics.
Findings
EJ offers opportunities for sport management researchers to form stronger analyses on existing racial, socio-economic, and gender-related inequities manifest in the sport industry. The incorporation of EJ can strengthen the emerging sport ecology research in sport management and offer opportunities for sport management researchers to form stronger analyses on existing racial, class and gender-related inequities manifest in the sport industry.
Originality/value
It provides a critical and original intervention to the sport management literature. EJ's emphasis on power and its position at the convergence of social movements, public policy, and scholarship hold important potential for sport management researchers to advance scholarship with “actions,” addressing environmental harms and seeking practical solutions for enhancing communities' well-being.
