Abstract

Purpose

The purpose of this paper is to investigate the effects of initial trust on control in the construction projects from the perspective of the client. The results are a good resource in managing the relationship between trust and control in the construction industry in China, and formulating a good working relationship with contractors.

Design/methodology/approach

Using a set of questionnaire, data were collected from project managers of the clients, who are responsible for the overall project management and have face-to-face interaction with the contractors. The data were analyzed by structural equation modeling to identify the effects of initial trust on control for the contractors.

Findings

Trust is examined in the construction industry in China through calculative and relational trust. Their effects are examined on three modes of inter-organizational control: outcome control, behavior control and social control. The results show that the calculative trust has strong effects on outcome-based and behavior control, while the relational trust, on social control.

Research limitations/implications

First, the conclusion of this research is based on the construction industry in China. It may not be suitable for other industries or other countries. Second, there may be other factors that influence the relationship between trust and control, such as the characteristics of the client and organizational culture, which are not taken into consideration in this research.

Practical implications

The effects of initial trust on control have been testified in the study. For the client, it is wise to take suitable control measures to face with the contractors with the consideration of initial trust. The contractors would apply the rule in the relationship between initial trust and control, and set up good relationship with the client.

Originality/value

This research has certain originality and value in theory and practice. First, this research analyzes the relationship between trust and control in a dynamical way, which has innovative significance to some extent. Second, research on inter-organization supplies a new perspective about project control. Finally, this research would offer a perspective to improve the present situation of the construction industry in China. If the clients use the trust and control measures appropriately, the harmonious relation can be achieved and projects performance can be improved.

This paper aims to present an investigation on flight quality analysis and design of tilt-rotor aircraft combined with corresponding flight quality specifications.

Abstract

Purpose

This paper aims to present an investigation on flight quality analysis and design of tilt-rotor aircraft combined with corresponding flight quality specifications.

Design/methodology/approach

From the perspective of modal characteristics of tilt-rotor aircraft, it focuses on the analysis of the change rules of the longitudinal short-term motion mode, lateral roll convergence mode, spiral mode and Dutch roll mode. Then, the flight quality design research is carried out using the explicit model tracking control method. The quantitative relationship between flight quality requirements and explicit model is established. Accordingly, the closed-loop flight quality of XV-15 tilt-rotor aircraft is evaluated.

Findings

The stability of spiral mode is the result of the interaction of various aerodynamic derivatives and spiral instability occurs in helicopter mode. The other motion modes are stable in full flight mode and meet the requirements of level 1 specified in ADS-33E-PRF and MIL-F-8785C flight quality specifications. There is a quantitative relationship between flight quality requirements and explicit model, and the flight quality of tilt-rotor aircraft is improved through the explicit model tracking control method.

Practical implications

The presented analysis results showed the influence of motion modes and flight quality and the effectiveness of explicit model tracking control method in flight quality improvement, which could be considered as new information for further flight quality design of tilt-rotor aircraft.

Originality/value

The originality of the paper lies in the proposed design and analysis method of the flight quality of tilt-rotor aircraft from the direction of the influence of its aerodynamic derivatives and motion modes.

Abstract

Purpose

The purpose of this paper is to propose a fault diagnosis method for rolling bearings, in which the fault feature extraction is realized in a two-dimensional domain using scale invariant feature transform (SIFT) algorithm. This method is different from those methods extracting fault feature directly from the traditional one-dimensional domain.

Design/methodology/approach

The vibration signal of rolling bearings is first transformed into a two-dimensional image. Then, the SIFT algorithm is applied to the image to extract the scale invariant feature vector which is highly distinctive and insensitive to noises and working condition variation. As the extracted feature vector is high-dimensional, kernel principal component analysis (KPCA) algorithm is utilized to reduce the dimension of the feature vector, and singular value decomposition technique is used to extract the singular values of the reduced feature vector. Finally, these singular values are introduced into a support vector machine (SVM) classifier to realize fault classification.

Findings

The experiment results show a high fault classification accuracy based on the proposed method.

Originality/value

The proposed approach for rolling bearing fault diagnosis based on SIFT-KPCA and SVM is highly effective in the experiment. The practical value in engineering application of this method can be researched in the future.

Abstract

Purpose

This study examines how ethical leadership (EL) influences followers' willingness to conduct unethical pro-organizational behavior (UPB) via reciprocity beliefs at the individual level and political climate at the group level.

Design/methodology/approach

Two-point survey data were collected from 423 Chinese followers from 81 groups, and multilevel structural equation modeling was conducted to test the hypotheses.

Findings

Individual-level EL unintentionally increases follower UPB willingness by fostering reciprocity beliefs, while group-level EL intentionally reduces follower UPB willingness by controlling the political climate. The political climate plays both a cross-level moderated mediation role and a mediated moderation role between EL and UPB.

Practical implications

When seeking to decrease followers' intention to conduct UPB, managers are advised to use individual-level EL with care when the focus is on reciprocity, and they should consider using group-level EL more when the focus is on controlling political climate.

Originality/value

The study supports two distinct mediating mechanisms by examining individual-level EL (as a moral person) vs group-level EL (as a moral manager) on UPB, thereby revealing the reason for the mixed effects of EL on UPB.

Abstract

Purpose

The purpose of this paper is to explore the heterogeneity and correlations of agricultural greenhouse gas (GHG) emissions among provinces in China, and then policy implications are proposed.

Design/methodology/approach

After agricultural GHG accounting and a pre-analysis of inter-provincial heterogeneity, improved gravity model and the Social Network Analysis (SNA) methods are introduced to construct the network, being carried out from three aspects of the whole network, individual provincial characteristics and cluster analysis.

Findings

(1) There are significant regional variations in agricultural GHG scale among provinces owing to the layout of agricultural production, and the temporal trends show that the direction and speed of agricultural GHG scale change vary among provinces; (2) In terms of inter-provincial correlations, there exists a complex spatial network of agricultural GHG among provinces, which tends to be more complex, intensive and stable, while the status of the provinces in the network also has gradually become more balanced. All provinces played their respective roles in the four clusters of the network with agricultural layout and comparative advantages, and the distribution has continuously optimized.

Practical implications

The inter-provincial network characteristics of agricultural GHG emissions and its evolution have practical implications for differentiated and coordinated agricultural GHG reduction policies at the provincial levels.

Originality/value

This paper innovatively study inter-provincial agricultural GHG correlations in China with the SNA methods used to study economic and social connections in the past. There is some originality in the introduction of network theory and application of the SNA methods, which can provide some reference for researches in similar fields.

Abstract

Purpose

The purpose of this paper is to examine the possibility that individual differences in consumer choice of cognac are at least partially influenced by parental cultural capital. Also examined are ten value orientations factors (e.g. hedonism and self-direction) and attitudes toward France, cognac’s country-of-origin that may affect the degree of this intergenerational influence.

Design/methodology/approach

The survey research measures parents’ cultural capital, value orientations and attitude toward France and purchase intention using recognized scales. Data were collected from the faculty and students of a major university located in the southeast of the USA. The sample size was 234.

Findings

The results confirm that parental cultural capital, consumer value orientations and attitudes toward France have significant impacts on the consumer’s willingness to purchase cognac. Adult children of high cultural capital parents are more likely to buy cognac.

Practical implications

The findings of this paper provide meaningful insights into intergenerational influences on consumer purchase intention of cognac and socialization theory. The paper provides several managerial implications for segmentation, targeting and positioning of cognac in the US market.

Originality/value

As the first of its kind, this paper introduces the parents’ cultural capital into the consumer research regarding cognac. The longer-term effects that parents can have on grown children’s consumer behavior are confirmed, suggesting that parental influence persists well into adulthood and has impact on their brand preference.

Abstract

Purpose

Improving the prediction accuracy of design time for complex products is significant for improving the accuracy of product development and control plans. The purpose of this study is to propose an intelligent pre-estimation method of design time for complex products based on v-SVM.

Design/methodology/approach

First, an evaluation model for designer knowledge abilities based on v-SVM is built, which considers the fuzziness and dynamics of designer knowledge abilities. Next, a pre-estimation method for the design time of complex products based on v-SVM is built. This method takes into account the impacts of designer knowledge abilities and design task characteristics on the design time. Then, an adaptive genetic algorithm is programmed to optimize the parameters in the evaluation model and the pre-estimation method. Finally, a practical application and comparative analysis of the proposed pre-estimation method is suggested to verify the validity and applicability of this research.

Findings

First, the evaluation of designer knowledge abilities is a prediction problem that is both fuzzy and multivariate time series. Second, the pre-estimation of design time is a problem that is fuzzy and multivariate. Third, the pre-estimation accuracy of the proposed method is higher when compared with traditional methods.

Originality/value

This paper presents an intelligent pre-estimation method of design time for complex products. Unlike previous research, the pre-estimation method takes into account the impacts of both the designer knowledge abilities and the design task characteristics on the design time.

Abstract

Purpose

As a relationship‐oriented culture, customer‐firm relationship plays an important role in consumer decision making process in China. Moreover, there are significant regional differences of Chinese consumers in terms of relationship proneness and its impact on relationship marketing outcomes. The purpose of this paper is to examine the differences of relationship proneness and its effect on relational satisfaction, relationship commitment and benefits between consumers from north and south of mainland China.

Design/methodology/approach

Based on previous research and relationship marketing theories, a series of hypotheses were developed comparing the two populations on relationship‐related variables. Data were collected from two cities of China using survey method.

Findings

Regional differences exist between the two groups of Chinese consumers in relationship proneness, commitment, trust, and relationship benefits perceptions. Gender differences also exist. Relationship proneness interacts with region resulting in moderating effects on relationship marketing outcomes.

Research limitations/implications

This research has treated two groups of Chinese consumers as cohorts and individual differences are not taken into consideration. The sample includes only graduate students whose attitudes toward relationship marketing may deviate from average consumers of the country as they have higher education levels but lower income levels.

Practical implications

The findings of the research provide managerial implications for marketing segmentation in China. International and domestic marketers should consider using different marketing strategies on consumers from different regions of China.

Originality/value

The paper confirms the regional differences of Chinese consumers in relationship proneness, trust, relationship benefits and commitment. The paper contributes to the relationship marketing literature by relating consumer relationship proneness to relationship benefits, and confirming the moderating effect of relationship proneness on relationship benefits and relationship commitment.
