Abstract

Purpose

The purpose of this paper is to provide a variety of viewpoints to illustrate the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges, which is validated by a symmetrical structure.

Design/methodology/approach

Based on the smooth and convergent bridge shapes obtained by the initial shape analysis, the one-element cable system (OECS) and multi-element cable system (MECS) models of the symmetric harp cable-stayed bridge are developed to verify the applicability of the analytical model and numerical formulation from the field observations in the authors’ previous work. For this purpose, the modal analyses of the two finite element models are conducted to calculate the natural frequency and normalized mode shape of the individual modes of the bridge. The modal coupling assessment is also performed to obtain the generalized mass ratios among the structural components for each mode of the bridge.

Findings

The findings indicate that the coupled modes are attributed to the frequency loci veering and mode localization when the “pure” deck-tower frequency and the “pure” stay cable frequency approach one another, implying that the mode shapes of such coupled modes are simply different from those of the deck-tower system or stay cables alone. The distribution of the generalized mass ratios between the deck-tower system and stay cables are useful indices for quantitatively assessing the degree of coupling for each mode. For each identical group of stay cables in the MECS model, the local modes with similar natural frequencies and normalized mode shapes consist of the participation of one or more stay cables. These results are demonstrated to fully understand the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges.

Originality/value

It is important to investigate the deck-stay interaction with the appropriate initial shape of a cable-stayed bridge. This is because such initial shape not only reasonably provides the geometric configuration as well as the prestress distribution of the bridge under the weight of the deck-tower system and the pretension forces in the stay cables, but also definitely ensures the satisfaction of the relations for the equilibrium conditions, boundary conditions and architectural design requirements. However, few researchers have studied the deck-stay interaction considering the initial shape effect. The objective of this paper is to fully understand the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges, which is validated by a symmetrical structure. The modal coupling assessment is also performed for quantitatively assessing the degree of coupling for each mode of the bridge.

Abstract

Purpose

The purpose of this paper is to examine the underlying mechanisms of how consumers respond to health-claim framing via experimental design.

Design/methodology/approach

Across the two experiments conducted for this research, the authors examine the moderating effects of self-perceived health status and individuals’ need for cognition on health-claim framing.

Findings

The results indicate that personal differences moderate the effects of health-claim framing on consumers’ food-product evaluation. Consumers with poor health status evaluate food product more favorably when the reduced-disease-risk claims are offered. However, consumers with good health status evaluate food product similarly between the two health claims. Moreover, consumers with a high need for cognition evaluate food product more favorably when the reduced-disease-risk claims are used, whereas consumers with a low need for cognition evaluate food product more favorably when the enhance function claims are used.

Practical implications

This research provides that reduced-disease-risk claims may be the better communication message used to persuade consumers no matter they rate themselves as poor health status or good health status. Moreover, the results of the present research also indicate the importance of market segmentation. Marketers could design proper advertisements and select the appropriate media vehicles for low need for cognition readers and high need for cognition readers separately.

Originality/value

There has been few studies addressed consumers’ product choice with respect to different health-claim framing. Further, this research presents a new concept of the effects between individual differences and health-claim framing on consumers’ food-product evaluation.

Abstract

Purpose

This paper aims to compare US market reactions to the restatement announcements of foreign firms listed in the USA and those of US firms by applying the Capital Market Liability of Foreignness (CMLOF) concept. It further investigates the incremental effect of an improved information environment, proxied by analyst following, on mitigating the negative market reaction to a restatement for foreign vs domestic firms.

Design/methodology/approach

Regression tests are performed on a matched-sample, which matches foreign and domestic firms based on industry and firm size. Market reaction is defined as three-day abnormal stock returns calculated using a market model. The sources of CMLOF are defined as institutional distance, information costs, unfamiliarity costs and cultural distance.

Findings

Results suggest that, on average, the magnitude of the market reaction to a restatement is 1.8 per cent lower for foreign firms than for domestic firms. Information and unfamiliarity costs contribute to the differing market reactions. In addition, it appears that the improved information environment created by a higher analyst following is more important for foreign firms who face CMLOF than for domestic firms.

Originality/value

While prior research establishes a negative market reaction to restatement announcements, comparing the market reactions for foreign and domestic firms provides evidence regarding whether US investors treat foreign and domestic firms differently. Additionally, to the best of the authors’ knowledge, this is the first study that examines CMLOF using restatement announcements.

Abstract

Purpose

This paper examines the impact of audit quality on the managerial preferences between real and accrual earnings management (REM and AEM, respectively) in oil and gas firms operating in the Gulf Cooperation Council (GCC) member countries.

Design/methodology/approach

The study relies on the modified Jones model’s (Dechow et al., 1995) to capture AEM and employs Roychowdhury (2006) approach to examine the use of REM through abnormal cash flows, abnormal production and abnormal discretionary expenditures. Audit quality is measured by auditor-industry specialization. The analyses are based on a sample of 30 oil and gas firms from 2008 to 2019.

Findings

The findings highlight that sample companies may substitute between earnings management strategies and tend to shift from AEM to REM when audited by an industry expert. Further analysis points out that the trade-off decision of the pooled sample stems from both upstream and downstream sectors.

Research limitations/implications

This study is subject to two main limitations. First, the narrowed scope of audit quality related factors due to the scarcity of corporate governance reports of companies. Second, the sample size is reduced.

Practical implications

The regulators and users of financial statements should be aware that REM strategy is used by oil and gas firms even when scrutinized by a high quality auditor, calling for extra caution when auditing or analyzing the financial information.

Originality/value

The current research is the first, unveiling the association between audit quality and the trade-off between AEM and REM in a less inspected sector and a unique institutional setting.
