To study strategic information transmission in organizations, we conduct a simplified version (with only three states) of the sender-receiver game experiment designed by Wang

Abstract

To study strategic information transmission in organizations, we conduct a simplified version (with only three states) of the sender-receiver game experiment designed by Wang, Spezio, and Camerer (2010), in which an informative sender advises an uninformed receiver to take an action (to match the true state), but has incentives to exaggerate. We also have the same subjects play the original five-state game. We find similar “overcommunication” behavior with Taiwanese subjects – messages reveal more information about the true state than what equilibrium predicts – that let us classify subjects into various level-k types. However, results from the simplified version are closer to equilibrium prediction, with more senders robustly classified as level-2.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between e-buyers and e-sellers in the context of the Chinese culture. It examines the relationships among swift guanxi, trust, uncertainty, and repurchase intentions. This study probes the possible mediation effects caused by the process where consumers form their thoughts and actions.

Design/methodology/approach

This study developed a theoretical model to examine how swift guanxi, trust, and uncertainty influence repurchase intentions of online auction consumers. The mediation effects of trust and uncertainty were also examined. This study gathered 455 valid samples and analyzed data by applying a structural equation modeling.

Findings

The results confirm that swift guanxi has significant and positive effects on trust and repurchase intentions, but swift guanxi has a significant and negative effect on uncertainty. In addition, trust has a significant and positive effect on repurchase intentions. On the other hand, uncertainty has a significant and negative effect on repurchase intentions. Finally, both trust and uncertainty have partial mediation effects between swift guanxi and repurchase intention.

Research limitations/implications

The findings extend the current state of knowledge about the relationships among swift guanxi, trust, uncertainty, and repurchase intentions, as well as reveal the psychological mechanism of the effects of trust and uncertainty on repurchase intentions.

Practical implications

The findings provide a deeper understanding of the effect of customers’ swift guanxi on repurchase intentions under different perspectives of the double-edged sword of trust and uncertainty in Yahoo! Online auction.

Originality/value

This study decomposes the constructs of swift guanxi, trust, and uncertainty into various dimensions and investigates the relationships between these dimensions and repurchase intentions. It has not been done in this way previously. The results contribute to the understanding of online auction customers’ behaviors.

Abstract

Purpose

Under the de-capacity circumstances of coal production in China, the purpose of this paper is to examine the processes underlying the association between job insecurity (JI) and miners’ safety performance, proposing that resource consumption is a prominent theoretical explanation for this association. By developing a mediation model, the authors examined the mediating role of emotional exhaustion (EE) between JI and miners’ safety performance.

Design/methodology/approach

Through the time-lagged survey method, the authors collected 349 samples from three coal mines in Shanxi Lu’an Group, the hypotheses were tested through confirmatory factor analysis, structural equation model analysis and bootstrapping in AMOS software.

Findings

Results shed light on that JI negatively predicts the safety performance subfactors, including safety compliance (SC) and safety participation (SP). EE plays a partial mediating role between JI and safety performance. In particular, the finding indicated that JI exerts a more significant impact on SP than SC, revealing that JI produces a more significant adverse effect on miners’ conscious safety behaviors than skill-based safety behaviors.

Originality/value

This study contributes to display the influence path of JI as a stressor on miners’ safety performance in the coal mine rather than a stimulus. The mediation model results not only help us understand the association between JI and safety performance but also provide a feasible way to mitigate the negative effects of JI.

Abstract

Purpose

During the construction process of the China Railway Track System (CRTS) I type filling layer, the nonwoven fabric bags have been used as grouting templates for cement asphalt (CA) emulsified mortar. The porous structure of nonwoven fabrics endowed the templates with breathability and water permeability. The standard requires that the volume expansion rate of CA mortar must be controlled within 1%–3%, which can generate expansion pressure to ensure that the cavities under track slabs are filled fully. However, the expansion pressure caused some of the water to seep out from the periphery of the filling bag, and it would affect the actual mix proportion of CA mortar. The differences in physical and mechanical properties between the CA mortar under track slabs and the CA mortar formed in the laboratory were studied in this paper. The relevant results could provide important methods for the research of filling layer materials for CRTS I type and other types of ballastless tracks in China.

Design/methodology/approach

During the inspection of filling layer, the samples of CA mortar from different working conditions and raw materials were taken by uncovering the track slabs and drilling cores. The physical and mechanical properties of CA mortar under the filling layer of the slab were systematically analyzed by testing the electrical flux, compressive strength and density of mortar in different parts of the filling layer.

Findings

In this paper, the electric flux, the physical properties and mechanical properties of different parts of CA mortar under the track slab were investigated. The results showed that the density, electric flux and compressive strength of CA mortar were affected by the composition of raw materials for dry powders and different parts of the filling layer. In addition, the electrical flux of CA mortar gradually decreased within 90 days’ age. The electrical flux of samples with the thickness of 54 mm was lower than 500 C. Therefore, the impermeability and durability of CA mortar could be improved by increasing the thickness of filling layer. Besides, the results showed that the compressive strength of CA mortar increased, while the density and electric flux decreased gradually, with the prolongation of hardening time.

Originality/value

During 90 days' age, the electrical flux of the CA mortar gradually decreased with the increase of specimen thickness and the electrical flux of the specimens with the thickness of 54 mm was lower than 500 C. The impermeability and durability of the CA mortar could be improved by increasing the thickness of filling layer. The proposed method can provide reference for the further development and improvement of CRTS I and CRTS II type ballastless track in China.

Abstract

Purpose

The construction of cement asphalt (CA) emulsified mortar can obviously disturb the slab status after the fine adjustment. To decrease or eliminate the influence of CA mortar grouting on track slab geometry status, the effects of grouting funnel, slab pressing method, mortar expansion ratio, seepage ratio and grouting area on China Railway Track System Type (CRTS I) track slab geometry status were discussed in this paper.

Design/methodology/approach

Combined with engineering practice, this paper studied the expansion law of filling layer mortar, the liquid level height of the filling funnel, the pressure plate device and the amount of exudation water and systematically analyzed the influence of filling layer mortar construction on the state of track slab. Relevant precautions and countermeasures were put forward.

Findings

The results showed that the track slab floating values of four corners were different with the CA mortar grouting and the track slab corner near CA mortar grouting hole had the maximum floating values. The anti-floating effect of “7” shaped slab pressing device was more efficient than fixed-joint angle iron, and the slab floating value could be further decreased by increasing the amount of “7” shaped slab pressing devices. After CA mortar grouting, the track slab floating pattern had a close correlation with the expansion rate and water seepage rate of CA mortar over time and the expansion and water seepage rate of the mortar were faster when the temperature was high. Furthermore, the use of strip CA mortar filling under the rail bearing platform on both sides could effectively reduce the float under the track slab, and it could also save mortar consumption and reduce costs.

Originality/value

This study plays an important role in controlling the floating values, CA mortar dosage and the building cost of projects by grouting CA mortar at two flanks of filling space. The research results have guiding significance for the design and construction of China's CRTS I, CRTS II and CRTS III track slab.

Abstract

Purpose

Concrete-filled double skin tube (CFDST) columns are considered one of the most effective steel-concrete composite sections owing to the higher load carrying capacity as compared to its counterpart concrete-filled tube (CFT) columns. This paper aims to numerically investigate the performance of axially loaded, circular CFDST short columns, with the innovative strengthening technique of providing stiffeners in outer tubes. Circular steel hollow sections have been adopted for inner as well as outer tubes, while varying the length of rectangular steel stiffeners, fixed inside the outer tubes only, to check the effect of stiffeners in partially and full-length stiffened CFDST columns.

Design/methodology/approach

The behaviour of these CFDST columns is investigated numerically by using a verified finite element analysis (FEA) model from the ABAQUS. The behaviour of 20-unstiffened, 80-partially stiffened and 20-full-length stiffened CFDST columns is studied, while varying the strength of steel (fyo = 250–750 MPa) and concrete (30–90 MPa).

Findings

The FEA results are verified by comparing them with the previous test results. FEA study has exhibited that, there is a 7%–25% and 39%–49% increase in peak-loads in partially stiffened and full-length stiffened CFDST columns, respectively, compared to unstiffened CFDST columns.

Originality/value

Enhanced strength has been observed in partially stiffened and full-length stiffened CFDST columns as compared to unstiffened CFDST columns. Also, a significant effect of strength of concrete has not been observed as compared to the strength of steel.
