This paper aims to provide a novel integrated fault detection method for industrial process monitoring.

A novel integrated fault detection method based on the combination of Mallat (MA) algorithm, weight-elimination (WE) algorithm, conjugate gradient (CG) algorithm and multi-dimensional Taylor network (MTN) dynamic model, namely, MA-WE-CG-MTN, is proposed in this paper. First, MA algorithm is taken as data pre-processing. Second, in virtue of approximation ability and low computation complexity owing to the simple structure of MTN, MTN dynamic models are constructed for each frequency band. Furthermore, the CG algorithm is used to discipline the model parameters and the outputs of MTN model of each frequency band are gained. Third, the authors introduce the WE algorithm to cut down the number of middle layer nodes of MTN, reducing the complexity of the network. Finally, the outputs of MTN model for each frequency band are superimposed to achieve outputs of MTN model, and fault detection is proceeded by the residual error generator based on the difference between the output of MTN model and the actual output.

The novel proposed method is used to perform fault detection for industrial process monitoring effectively, such as the Benchmark Simulation Model 1 wastewater treatment process.

The novel proposed method has generality and provides considerably improved performance and effectiveness, which is used to perform fault detection for industrial process monitoring. The proposed method has good robustness, low complexity and easy implementation.

This paper aims to investigate multidimensional customer engagement behaviors (CEBs) as antecedents of action loyalty in hospitality contexts and examine service conditions that inhibit and facilitate the former relationship.

This paper tests a holistic framework based on transaction data from 5,855 active members of a hotel firm. The hypotheses are examined using ordinary least squares regression.

By integrating transaction-related CEBs with non-transaction-related CEBs, this paper found that three CEB constructs (i.e. feedback, mobilizing and cross-buying) contribute significantly to action loyalty in hospitality contexts. These effects vary depending on the inhibitor (service failure) and the facilitator (service customization).

Hotel managers should value customer engagement as a marketing tool to retain customers. When engaged customers encounter service failure and customization, managers can react differently to facilitate consumers’ action loyalty.

Contrary to prior studies focusing on the effects of general CEBs on attitudinal loyalty, this study examines the diverse impacts of multidimensional CEBs on customers’ action loyalty and confirms boundary conditions to coordinate the effects between CEBs from a hotel firm’s perspective.

The purpose of this paper is to identify the double-edged sword of customer involvement (perceived relationship quality and coordination cost) in new service development in the hotel industry, and to explore when customers should be involved from the service provider’s view.

A total of 252 valid questionnaires were collected from hotel managers, and ordinary least squares regression analysis was conducted to test the hypotheses.

Results not only show that customer involvement causes higher coordination cost but also show no direct positive effect on perceived relationship quality. Furthermore, this study finds that service climate reduces the negative effect of customer involvement and enhances its positive effect. By contrast, customer complexity intensifies the negative effect of customer involvement.

This study empirically examines the double-edged sword of customer involvement and tests the boundary conditions associated with hotel back and front office factors (service climate versus customer complexity).

The purpose of this paper is to explore the transformation from service engagement through hotel consumption behavior to subsequent product purchases and identify marketing strategies to facilitate this transformation.

Using a 1.5-year data set of transactional data from a typical hotel firm, the authors examined 4,999 valid purchase events via ordinary least squares regression to test the hypotheses proposed.

Contrary to studies indicating that heavy hospitality users are resistant to external change, the authors found that hotel service engagement (in terms of recency, frequency and monetary value) significantly informed subsequent product purchases. Effects varied based on customized solutions and product purchase channel.

Product managers in hospitality should target customers who have recently patronized hotels as well as hotel customers with high monetary value and frequency. Managers can adopt distinct marketing strategies (e.g. customized solutions and purchase channels) to sell hotel customers more products.

Prior studies have framed the cross-selling of hospitality services as a vital revenue management strategy from hotel firms’ or frontline employees’ perspectives. However, to the best of the authors’ knowledge, this is the first study to test how hotels cross-sell tangible products by targeting customers engaging in hotel consumption and by examining two major product marketing strategies that may facilitate or hinder this cross-selling process.

This study aims to examine how three types of information technology (IT) capability (supplier technological capability, customer technology-sensing capability and relatedness of IT infrastructure) facilitate knowledge acquisition by the customer when the supplier is dominant in the supplier-customer relationship.

The unit of analysis was project. The authors designed two different questionnaires that were responded by the project manager of an enterprise resource planning (ERP) software supplier and the contact person of the customer organization in the same project, respectively. The two questionnaires were matched by means of project name. The final sample included a total of 136 projects. The authors used ordinary least squares to test the research hypotheses.

The authors found that supplier power advantage negatively influenced knowledge acquisition by the customer. The three types of IT capability did not have direct impacts on knowledge acquisition. The moderating effect of customer technology-sensing capability was not significant either. However, supplier technological capability and relatedness of IT infrastructure attenuated the negative effect of supplier power advantage on knowledge acquisition, indicating that both factors promoted knowledge acquisition.

Knowledge acquisition is important for the success of software implementation in the supplier-customer relationship. There is limited evidence in the literature on how to apply externally oriented IT capability to enhance knowledge management, improve knowledge acquisition and manage the business relationship that is typically dominated by the software supplier. The authors provide evidence to examine related issues.

Global brands are attracted to emerging markets because of increasing wealth among their middle classes. However, amid increasing levels of consumer financial stress in many emerging markets, evidence points towards increased preferences for domestic products. The purpose of this paper is to examine the psychological constructs that mediate and moderate the relationship between reduced perceived financial well-being (PFWB) and domestic product purchases.

The authors develop a model drawing from three theoretical perspectives: consumer stress and coping, consumer information processing and social identity theory. Hypotheses are tested via structural equation modelling and moderated mediation analyses using data from a survey of Brazilian consumers (n=1,043).

Results show that the positive relationship between reduced PFWB and domestic product purchases is partially mediated by perceived value of global brands and frugality descriptive norm. Further analyses demonstrate that consumer confidence moderates the mediating effects of perceived value of global brands and pro-social consumer ethnocentrism on the relationship between reduced PFWB and domestic product purchases.

The antecedents of domestic product purchases identified in this study indicate opportunities for marketers of domestic and foreign products to respond to reduced PFWB, especially in relation to pricing, branding and communications. Future research should examine implications of PFWB on different populations, including other emerging markets, developed markets and lower-income consumers.

This study contributes to international marketing literature by examining the hitherto unexplored influence of reduced PFWB on domestic product purchases.

Limited research has paid attention to the physical attractiveness stereotype in peer-to-peer sharing accommodation settings. Since the high-risk situations in sharing accommodations, this paper aims to exam whether beauty premium is still relevant in peer-to-peer (P2P) accommodation.

The mixed method, including 2,506 secondary data analysis and two scenario experiments, is carried out to test the research framework.

The results show that both beauty premium and beauty penalty exist in the e-commerce context. Excessively high attractiveness and plain looking of hosts are likely to decrease consumers’ booking decision while moderately attractive hosts will stimulate more booking behaviors. Moreover, perceived trustworthiness mediates the effect of physical attractiveness on booking decision. Additionally, similarity between hosts and consumers plays a moderating role in the relationship between physical attractiveness and perceived trustworthiness.

This study reveals the physical attractiveness stereotype effects in P2P accommodation and carry implications to P2P platforms and hosts for providing moderately attractive profile photos, enhancing trustworthiness and similarity between hosts and consumers. Further studies can investigate the robustness of the findings as well as more possible reasons for its occurrence.

The research provides a clearer understanding of physical attractiveness stereotype effect in peer-to-peer sharing accommodation platforms. Besides, the linkage between physical attractiveness and perceived trustworthiness is dynamic; a high host – consumer similarity weakens the negative impact of both excessively high attractiveness and plain looking on consumers’ perceived trustworthiness.

Drawing upon cognitive control theory, we examine the effects of self-regulation failure (SRF) on the relationships between perceptions of organizational politics (POPs) and tension, exhaustion, satisfaction, work effort, perceived resource availability and performance/contribution.

We test hypotheses across three unique studies (Study 1: 310 employees from various occupations; Study 2: 124 administrative/support employees; Study 3: 271 Chinese hotel managers) using hierarchical moderated regression analyses.

Across studies, results suggest that POPs had a minimal impact on work attitudes, behaviors and health-related outcomes when SRF was low. However, employees experiencing high SRF reported adverse consequences in high POPS settings.

These studies relied on self-report data. However, we implemented design features to mitigate potential concerns and analytic techniques to determine method effects. This paper contributed to the POPs literature by explaining how SRF and POPs interact to impact meaningful work outcomes.

Leaders should receive training to help them identify and address indicators of SRF. Leaders can also implement intervention programs to help calm employees who experience SRF.

Leaders should receive training to help them identify and address indicators of SRF. Leaders can also implement programs to help assist employees who demonstrate adverse effects from SRF.

This paper integrates the research on SRF and politics to examine the collective impact these variables have on workers. Our three-study package also addresses the call for more studies to examine how politics operate across cultures.

This paper aims to reasonably quantify the radial deformation of turbine blade from a probabilistic design perspective. A probabilistic design for turbine blade radial deformation considering non-linear dynamic influences can quantify risk and thus control blade tip clearance to further develop the high performance and high reliability of aeroengine. Moreover, the need for a cost-effective design has resulted in the development of probabilistic design method with high computational efficiency and accuracy to quantify the effects of these uncertainties.

An extremum response surface method-based support vector machine (SVM-ERSM) was proposed based on SVM of regression to improve the computational efficiency and precision of blade radial deformation dynamic probabilistic design regarding non-linear material properties and dynamically thermal and mechanical loads.

Through the example calculation and comparison of methods, the results show that the blade radial deformation reaches at the maximum at t = 180 s; the probabilistic distribution and inverse probabilistic features of output parameters and the major factors (rotor speed and gas temperature) are gained; besides, the SVM-ERSM holds high computational efficiency and precision in the non-linear dynamic probabilistic design of aeroengine typical components.

The present efforts provide a method to design turbine besides other aeroengine components considering dynamic and non-linear factors base on probabilistic design for further research.

Moreover, the present study provides a way to design dynamic (motion) structures from a probabilistic perspective.

It is proved that the dynamic probabilistic design-based SVM-ERSM could produce a more reasonable blade radial deformation while maintaining low failure probability, as well as offer a useful reference for blade-tip clearance control and a promising insight to the optimal design of aeroengine typical components.
