Abstract
Purpose
To meet the high stiffness requirement of bearings used in high-precision spindles, this paper aims to propose a novel kind of bearing composited by hydrostatic cavities and tilting pads with preload.
Design/methodology/approach
Cavities are cut on the oil seal surface of a hybrid bearing, in which the tilting pads are set up. The load of the bearing is carried by the hydrostatic cavities and tilting pads. The structural features of this compound bearing and the controlling variables of the main stiffness coefficient are presented. Two basic design principles are proposed on the basis of equal machining clearance (EMC) and equal installation clearance (EIC).
Findings
The theoretical analysis indicates that the stiffness of compound bearings under the EMC condition increases to infinity monotonously when the preload coefficient of the tilting pad tends to 1, while the stiffness under the EIC condition has a peak value. Therefore, a synthetic design principle is proposed by synthetically using the above-mentioned two principles. The applicable range of the three principles is discussed through an example.
Originality/value
The study about technological combination of hydrostatic cavity and tilting pad in this paper can provide suggestions for the design of a high-stiffness bearing in a precision spindle.

Abstract
Purpose
An ideal method for predicting the fatigue life of spherical thrust elastomeric bearings has not been reported, thus far. This paper aims to present a method for predicting the fatigue life of laminated rubber spherical thrust elastomeric bearings.
Design/methodology/approach
First, the mechanical properties of standard rubber samples were tested; the axial stiffness, cocking stiffness, torsional stiffness and fatigue life of several full-size spherical thrust elastomeric bearings were tested. Then, the stiffness results were calculated using the neo-Hookean, Mooney–Rivlin and Yoeh models. Using a modified Mooney–Rivlin constitutive model, this paper proposes an improved method for fatigue life prediction, which considers the laminated characteristics of a spherical thrust elastomeric bearing and loads of multiple multi-axle conditions.
Findings
The Mooney–Rivlin model could accurately describe the stiffness characteristics of the spherical thrust elastomeric bearings. A comparative analysis of experimental results shows that the model can effectively predict the life of a spherical thrust elastomeric bearing within its range of use and the prediction error is within 20%.
Originality/value
The fatigue parameters of elastomeric bearings under multiaxial loads were fitted and corrected using experimental data and an accurate and effective multiaxial fatigue-life prediction expression was obtained. Finally, the software was redeveloped to improve the flexibility and efficiency of modeling and calculation.

Abstract
Purpose
This paper aims to determine the effect of personal values and buying intention on repurchase intention. This paper is based on the social exchange theory (Cropanzano and Mitchell, 2005) as a basis for understanding the relationship between tourists who give or exchange each other that contains embraced values or personal values between individuals from tourists based on certain social arrangements placing a moderating variable. As an illustration of social phenomena, especially tourism, which shows a non-linear relationship.
Design/methodology/approach
This study used a mixed-method research, combining quantitative and qualitative research techniques, in a single study. The use of mix method research is based on the consideration that the research variables are variables that are rarely used in previous studies so that there is limited literature to explain the research results. In the early stages of the research, a questionnaire was compiled based on all the research variables mentioned above. The questionnaire was then distributed to 160 respondents. The pre-test was carried out using the construct validity and the assistance of the SPSS 13.0 program for the level of reliability. The questionnaire was distributed using the purposive sampling method. The number of samples taken at each tourist attraction was 40 respondents in each tourist destination, namely, Nusa Dua, Kuta, Tanah Lot, Sanur and Ubud. Bali, fits the criteria of Hair et al. (2014).
Findings
This study has two novelties, the first is demographic variable that positions as a moderating variable the influence of personal value on buying intention and personal value on repurchase intention; and the second variable buying intention as an intervening variable between the influence of personal value on repurchase intention.
Research limitations/implications
This study has a limitation in that the questionnaire was only distributed to tourist destinations in Kuta, Nusa Dua, Sanur, Tanah Lot and Ubud. The object of this research is only focused on Chinese tourists, not other tourists either. Furthermore, this study does not distinguish between tourists who visit for the first time and tourists who visit several times which may be a moderating variable for the influence of personal value and buying intention on repurchase intention and the influence of personal value on buying intention.
Practical implications
The practical implications are as follows: tourism managers can use a tourism destination marketing strategy model that integrates independent and moderating variables in increasing buying intention and repurchase intention for Chinese tourists visiting Bali. Strategies that can be carried out by tourism managers in increasing buying intention and repurchase intention of tourists to visit Bali by identifying and creating values that are understood as values for tourists visiting Bali (personal value).
Social implications
Personal values that are adjusted to trends in the world of tourism that are felt and desired by a destination through tourists visiting Bali are one of the marketing strategies for tourism managers to increase the buying intention and repurchase intention of these tourists.
Originality/value
This study integrates personal values, demographics, buying intention and repurchase intention in evaluating Chinese tourists visiting Bali. Demographic variables in Chinese tourists as moderating variables based on age, education, gender, family, including their region of origin, it is very important to pay attention to the unique characteristics of Chinese tourists and the main differences between them, as an illustration of social phenomena, especially tourism, which shows a nonlinear relationship.

The aim of this study is to investigate the impact of local political uncertainty on the asymmetric cost behavior (i.e. cost stickiness) for listed firms in China.
Abstract
Purpose
The aim of this study is to investigate the impact of local political uncertainty on the asymmetric cost behavior (i.e. cost stickiness) for listed firms in China.
Design/methodology/approach
In this study, the authors manually collect the turnover data of prefecture-city officials as a measure of exogenous fluctuations in political uncertainty and obtain firm-level financial information from the China Stock Market Accounting Research (CSMAR) database. To perform the analysis, the authors augment the traditional cost stickiness model by including the interaction terms of the prefecture-city official turnover, and firm-level and prefecture-city level control variables.
Findings
The authors find that political turnover leads to a higher degree of cost stickiness, implying that firms retain slack resources when political uncertainty is high. Moreover, the effect of political turnover on cost stickiness is more pronounced for firms residing in regions with weaker institutional environments, and firms that are privately owned and with smaller size. The authors further provide evidence that policy uncertainty and the threat of losing political connection are two underlying channels. Overall, this study documents that the local political process is an important channel that influences corporate operational decisions.
Originality/value
This study provides the first piece of evidence on the relation between political uncertainty and cost stickiness at the local government level. Moreover, the authors propose and demonstrate two underlying channels through which political uncertainty affects firms' asymmetric cost behavior.
