The purpose of this paper is to examine the effect of self-worth on status consumption, focusing on the mediation of self-enhancement and self-compensation and the moderation of power distance belief (PDB) in the relationship of threats to self-worth and consumer choice.

Experiments are used to collect data. Three studies are designed to test the relationship between self-worth, self-enhancement and self-compensation, PDB and status consumption. In total, 180 MBA students participate Study 1, 186 and 244 undergraduate students participate Studies 2 and 3, respectively. ANOVA and bootstrapping method are adopted to analyze the data by using SPSS version 19.0. Study 1 tests the influence of self-worth on status consumption; Study 2 examines the mediation role of self-enhancement and self-compensation; and Study 3 tests the moderation role of PDB.

Results indicate that situational self-worth perception has dual path effects on status consumption. Both improvements in – and threats to – self-worth have a positive impact on status consumption. Improvements in self-worth affect status consumption through the mediation of self-enhancement motives. Threats to self-worth affect status and non-status consumption through the mediation of the self-compensation motive. In the context of a threat to self-worth, compared with consumers with a low PDB, high-PDB consumers have higher purchase intention for status goods but not non-status goods.

In this study, improvements in – and threats to – self-worth are momentarily manipulated. The authors present one product in each experiment, but what would happen if both status goods and non-status goods were shown to participants? Which one will the authors choose under different self-worth manipulations? And how long can the effects last? These questions should be answered in future research.

This research provides a venue for marketers to introduce and advertise status goods. Marketing practitioners should establish the link between self-worth and status consumption appeals. In the Asia-Pacific markets, Confucian value is important to consumers, and high power distance is important in Confucianism. Thus when developing markets in China, international companies should emphasize Confucian values in the design of advertisements or other promotional items. Further, marketing for status goods should attach importance to the expression of their symbolic meanings.

This study contributes to the literature on self-worth and status consumption. It also explores the dual path of the effect of self-worth on status consumption. The motives of self-enhancement and self-compensation are first proposed and tested to explain the mechanism, which differentiates the study from prior work and gives a more reasonable explanation for status and compensatory consumption. The moderation role of PDB delineates the boundary for the effect of a threat to self-worth on status consumption.

This article is the fourth part of a serial studies about constant and variable compensations of the closed-type hydrostatic plane-pad bearing, which is presented for the double-action membrane-type restrictor and self-type compensation. The paper aims to discuss these issues.

The load capacity and static stiffness in thrust direction of the planar bearing is determined by the flow continuity equation which belongs to the same approaches as shown in previous parts of this serial studies.

The results reveal that the appropriate range of recess pressure ratio and design parameters of bearing and restrictor for the infinite or maximum stiffness can be obtained. Also, the influence of design parameters on negative stiffness that should be avoided in bearing design is revealed in detail.

The determination of design parameters of a double-action membrane-type restrictor can be yielded from finding results of this study for maximum stiffness in design of hydrostatic bearings.

It has been noted that the spin-valve sensor exhibits lower sensitivity with higher temperature because of the variation of GMR ratio, which could lead to the measurement error in applications where working temperature changes largely over seasons or times. This paper aims to investigate and compensate the temperature effect of the spin-valve sensor.

A spin-valve sensor is fabricated based on microelectronic process, and its temperature relevant properties are investigated, in which the transfer curves are acquired within a temperature range of −50°C to 125°C with a Helmholtz coil and temperature chamber.

It is found that the sensitivity of spin-valve sensor decreases with temperature linearly, where the temperature coefficient is calculated at −0.25 %/°C. The relationship between sensitivity of spin-valve sensor and temperature is well-modeled.

The temperature drift model of the spin-valve sensor’s sensitivity is highly correlated with tested results, which could be used to compensate the temperature influence on the sensor output. A self-compensation sensor system is proposed and built based on the expression modeled for the temperature dependence of the sensor, which exhibits a great improvement on temperature stability.

This paper aims to propose a hybrid method based on polynomial fitting bias self-compensation, grey forward-backward linear prediction (GFBLP) and moving average filter (MAF) for error compensation in micro-electromechanical system gyroscope signal especially under motion state.

The error compensation can be divided into two processes: bias correction and noise reduction. A polynomial drift angle fitting algorithm is used to correct bias before denoising processing. For noise reduction, operation can be taken in two stages: detection and processing. First, sample variances are used to judge motion state. According to the detection results, algorithmic system switches between grey GFBLP and MAF to ensure fast convergence rate and small steady-state error.

Experimental results show that the proposed method can correct bias effectively for practical gyroscope signal, and can eliminate noise effectively for both practical gyroscope signal and synthetic signal, which indicates the effectiveness of the proposed method.

Bias correction and noise reduction are considerations. Noise contained in practical or synthetic signal can be reduced rapidly and effectively, which benefits from the new idea of combination grey GFBLP, MAF and sample variances. And most importantly, it is applicable for signal denoising under arbitrary motion state condition, which is different from other methods where the convergence performance is seldom analyzed.

This paper aims to develop a low-cost hot-point which can facilitate the conductivity type of N-type and P-type zinc oxide (ZnO) films. In this study, a diode was made out of the N-type and P-type ZnO films, and current-voltage (I-V) characteristic measurements were conducted.

A low-cost hot-point probe consists of a soldering iron station, digital multimeter and a pair of probes. The setup is adopted to identify N-type and P-type ZnO films. In particular, P-type films have been deployed for the first time.

Hot-point probe setup has been successfully developed. Measurements of N-type films give a positive voltage reading, whereas P-type films give a negative voltage reading. The measured voltage dominates at 1 per cent for N-type Ga and at 15 per cent for P-type Na. I-V characteristics of the fabricated diode showed a similar trend to the conventional diode.

N-type has been often attempted. However, P-type has rarely been attempted because of the self-compensation effect in ZnO. There is a need to verify the conductivity type of ZnO films, especially P-type, as P-type films are not stable. The hot-point probe setup serves as a quick means to verify P-type ZnO films.

To the best of the authors’ understanding, this verification tool was developed and deployed to verify the N-type and P-type ZnO films. The P-type films are coated on top of the N-type films for diode I-V measurements.

The purpose of this study is to present the state of the art for fiber Bragg grating (FBG) acceleration sensing technologies from two aspects: the principle of the measurement dimension and the principle of the sensing configuration. Some commercial sensors have also been introduced and future work in this field has also been discussed. This paper could provide an important reference for the research community.

This review is to present the state of the art for FBG acceleration sensing technologies from two aspects: the principle of the measurement dimension (one-dimension and multi-dimension) and the principle of the sensing configuration (beam type, radial vibration type, axial vibration type and other composite structures).

The current research on developing FBG acceleration sensors is mainly focused on the sensing method, the construction and design of the elastic structure and the design of a new information detection method. This paper hypothesizes that in the future, the following research trends will be strengthened: common single-mode fiber grating of the low cost and high utilization rate; high sensitivity and strength special fiber grating; multi-core fiber grating for measuring single-parameter multi-dimensional information or multi-parameter information; demodulating equipment of low cost, small volume and high sampling frequency.

The principle of the measurement dimension and principle of the sensing configuration for FBG acceleration sensors have been introduced, which could provide an important reference for the research community.

This paper aims to study the impact of external fairness of executive compensation on M&A premium, and examine the moderate role of institutional investors. The high M&A premium is the main factors that induce the huge impairment of listed companies’ goodwill and the plummeting performance. Executives are the decision-makers of M&As, and their decision-making process is inevitably affected by the psychological factors. In recent years, institutional investors have become an important external force that can affect the governance of listed companies.

The authors use M&A data of listed companies from 2008 to 2018 and use OLS regression to test the relationship between executive compensation fairness and M&A premium.

The results show that the lower the external fairness of executive compensation, the greater the M&A premium. Institutional investors can effectively reduce the impact of external compensation unfairness on M&A premiums. The mechanism tests show that executives' psychological perception of fairness induced by external unfairness reduces their motivation to work and prompts them to use high premium to seek alternative compensation incentives. Further examinations of executive characteristics and corporate characteristics show that the role of external unfairness in executive compensation in driving M&A premiums is more pronounced in companies with longer executive tenure, weaker executive reputation incentives and private property.

This paper enriches the research on the pre-factors of M&A premiums from the perspective of executives’ psychological perception of fairness, provides evidence that institutional investors play a positive governance role and provides decision-making references for companies to take corresponding measures to reduce M&A premium risks.

Describes how homeostatic models can be applied to modelling the normal processes, as well as the critical phenomena, such as paralysis, shock or collapse, which work in the polarised world. Discusses the development of civilisation against a background of the fight for resources, territories, spheres of influence, as well as the war between the technologies, behind which are the people. This produces an ultimately bad effect upon the ecology. Thus, unless the human race does not think better of it and changes the prevailing paradigm in relation to the nature and to the people themselves, a bitter pay‐off – the global ecological catastrophe – is due. Outlines a created simulating model of the community, which shows that a global ecological catastrophe is likely to occur between 2020 and 2050. This time frame represents a zone of bifurcation, which, it is said, may result in either the death of civilisation, or an excruciating process of rebirth, which would also involve a transition to the new information technologies (based on the principles of the plasma, vacuum, or torsion fields, and so forth). In order to avert the global ecological catastrophe, suggests that it is necessary to accept the noospheric thinking code and, among other changes the organisational structure of the United Nations Organization (UNO), and the relationships between countries.

The coefficient of thermal expansion (CTE) and modulus of elasticity (ME) values of mortar and stone from room temperature to cryogenic temperatures provide an experimental basis for the design of liquefied natural gas (LNG) storage tanks.

The CTE and ME of mortar and limestone were measured by resistance strain gauge testing technology at cryogenic temperatures.

The test results showed that CTE values of mortar and stone decreased with the decrease of temperature and CTE values of mortar was greater than that of stone from 0 °C to −165 °C. The ME values of mortar increased significantly at cryogenic temperatures, and less change in stone.

The material at cryogenic temperatures may continue to work in the elastic phase due to the continuous increase of elastic modulus. Therefore, the study of material in the elastic stage may be more important than in the ultimate bearing capacity stage, and it is necessary to carry out further study surrounding the deformation properties of materials at cryogenic temperatures. The CTE and ME values of mortar and stone from room temperature to cryogenic temperatures provide an experimental basis for the design of LNG storage tanks.
