Abstract
Purpose
The purpose of this paper is to present a novel scheme of high‐dynamic global positioning system (GPS) software receiver in order to improve the capturing speed and trading accuracy of GPS receiver.
Design/methodology/approach
First, the beginning of C/A code can be found through the delay and multiply approach. To solve the problems of estimating a certain satellite's Doppler shift from the signals of several visible satellites, the “delay and accumulation unit” is put forward, and besides, performance of inertial navigation system‐assisted tracking loop in high‐dynamic circumstance is analysed by means of mathematical modelling and simulation experiments, whose results verified the validity of the proposed tracking scheme.
Findings
In this paper, the two‐dimension searching process in conventional acquisition scheme is transformed into two one‐dimension searching processes, thus improving the capturing speed.
Research limitations/implications
This software receiver has only been verified by means of mathematical simulation, and the validity in hardware receiver is still obscured.
Originality/value
This paper presents a novel high‐dynamic GPS software receiver scheme, which can be seen as a reference of engineering application and simulation research.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Practical implications
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.
Originality/value
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.

The purpose of this paper is to study the influence of perceived control on product preferences of consumers under self-threat.
Abstract
Purpose
The purpose of this paper is to study the influence of perceived control on product preferences of consumers under self-threat.
Design/methodology/approach
By conducting four experiments, this paper manipulated the participants’ self-threat and three sources of perceived control – namely, the controllability of the threat itself, the internal and external locus of control of the individual and priming the existing positive or negative experience of the individuals. After the manipulations, the participants’ product preferences for self-growth goods or hedonic goods were measured.
Findings
The findings of this research indicated that when consumers have a higher perceived control of the threats they are facing, they are more likely to adopt problem-focused coping strategies and show a preference for self-growth goods, which can help them resolve their threats. However, when consumers have a lower perceived control on the threats they are facing, they are more likely to adopt emotion-focused coping strategies and show a preference for hedonic goods, which can help them adjust their emotions.
Originality/value
This paper systematically confirms the interactive effect of perceived control and self-threat on consumers’ product preferences, as well as the meditation role of problem-focused coping and emotion-focused coping. It also provides insights for marketers to know what factors may affect consumers’ preferences for products in self-threat situations, thus contributing to marketing practices.
