Abstract

Purpose

Recent studies have proposed the application of local fatigue approaches based on fracture mechanics or on strain-life material relations for the fatigue analysis of metallic structures. However, only few studies in the literature apply local approaches in the riveted bridges analysis; although these approaches can be applied to any type of connections, requiring a detailed stress analysis of joints and, consequently, considerable computational resources costs. The approach based on S-N curves, formulated in nominal or net stresses, is more usual in the fatigue analysis of riveted bridges. Due to economic factors, riveted bridges have had their operating life extended, while changes in the transport system over the years have subjected such structures to overloads different from those originally planned. These bridges, most of them centenary, were not originally designed accounting for fatigue damage; they represent an important group of structures that are very likely subjected to significant fatigue damage indexes. These factors make necessary detailed residual fatigue life studies to substantiate the decisions of extend (or not) the operational period of these bridges. The paper aims to discuss these issues.

Design/methodology/approach

The present paper presents a methodology aiming at applying the local approaches in the fatigue analysis of riveted joints of metallic bridges, through the use of sub-modeling techniques and procedures automation. The use of such techniques made such an application viable by keeping the computational costs involved at a moderate level. The proposed procedures were demonstrated using the Trezói Railway Bridge, located on the Beira Alta line, Portugal, built shortly after the Second World War. The proposed set of procedures allowed, through finite elements analysis, to obtain the relevant stresses to perform local fatigue damage analysis. A global structural model was constructed, using beam elements, and local models of a critical node were built with solid finite elements. The structure is analyzed under the passage of regulatory trains. The details of the modeling performed and the computation of the principal stresses in the vicinity of a node and the tangential/circumferential stresses at the holes of two critical riveted connections of that node are analyzed and a fatigue damage analysis is carried out.

Findings

In the proposed submodelling approach, disassembling the complex riveted nodes into riveted subassemblies allowed the evaluation of the local stresses at riveted holes at an affordable computational cost.

Originality/value

A methodology is proposed to allow the application of local fatigue analysis in real complex riveted joints, mitigating the computational costs that would result from a full model of the node with all rivets.

Abstract

Purpose

The purpose of this paper is to investigate consumer preferences towards innovative rice products, and cross-cultural determinants of customers’ perceived value and loyalty.

Design/methodology/approach

A self-administered survey was designed to obtain participants’ perceptions about Thai rice, and preferences towards innovative Thai rice products. A total of 937 surveys were distributed and 908 valid surveys were returned, yielding a 96.7 per cent overall response rate. Confirmatory factor analysis was used to assure the reliability and validity of the measures used in the survey instrument. Structural equation modelling was employed to assess the five hypothesised relationships between the four elements of the marketing mix, customer perceived value, and post-purchase behaviour, and to compare the path coefficients across the two cultural groups.

Findings

The findings reported herein show that eastern and western customers’ perceptions of marketing mix variables positively impact their perceptions of value, in turn, enhancing their loyalty to Thai rice. A successful marketing strategy should meet changing customer needs through adopting new products, services and unique marketing mix bundles. Such strategies should be tailored to the differing needs across cultures, and can address issues arising from changing competitive and environmental landscapes.

Research limitations/implications

The first limitation concerns the scope of the study. Specifically, the authors only conducted surveys during a two-month time period in 2018; the sampling sites were limited to several shopping malls in Bangkok; and the authors surveyed a high proportion of young, single, educated participants. The second limitation pertains to the selection and adaptation of constructs and their observed variables (such as the 4P indicators). Most of the observed variables were selected based on a literature review and the opinions of the scholars who participated in this study.

Practical implications

These results should be beneficial to members of the international rice industry, Thai rice exporters, the Thai government and to academics. Long-term success will be supported by focused attention on target segments and launch of innovative rice products that match differing preferences across nationalities.

Originality/value

Understanding consumers’ perspectives and preferences are critical to appropriate positioning and marketing of value-added Thai rice products. This study represents one of the first attempts to integrate marketing mix decisions, customers’ perceived value and loyalty within a Thai rice purchase behaviour context across eastern and western customers.

Abstract

Purpose

This chapter explores social media and athlete mental health and well-being from a sociological perspective. The chapter provides an overview of current literature and encourages future research to address the mental health and well-being impacts of social media use among athletes.

Design/methodology/approach

The chapter synthesizes existing literature focusing on sociological approaches to mental health, social media's impact on mental health, and athlete mental health and well-being. Focus is given to the ways social media can impact athlete mental health and well-being through virtual maltreatment and using the platforms for social change and challenging stigmatization.

Findings

Virtual maltreatment typically manifests in the intersectionality between gender, race, and sexual orientation adding to mental health challenges of vulnerable groups. Conversely, athletes could help challenge stigmatization of mental health and use their status to create social change among social groups experiencing higher rates of mental health challenges.

Research limitations/implications

The chapter reveals that sociological perspectives around athlete mental health and well-being related to social media are growing, yet predominately concentrate on publicly available social media content. Therefore, more concentrated efforts are needed to fully understand these impacts in the short and long-term.

Originality/value

The chapter provides one of the first insights on social media and athlete mental health and well-being from a sociological perspective and argues that athletes contend with unique stressors compared to the general population which can exacerbate mental health challenges. The chapter advances that more research is needed to inform practice and help safeguard vulnerable populations of athletes.

Abstract

Key account management plays a pivotal role for managers and practitioners in maintaining successful customer–supplier relationships. Yet, little is known conceptually and empirically as to how suppliers can develop international key account management capabilities in international customer–supplier relationships. Drawing from resource-based view and dynamic capability literature, we develop and test a model of the impact of IT capabilities on international key account management capabilities and firm performance. An explorative case study of Taiwanese electronics suppliers reveals that IT capabilities are critical to develop supplier international key account management capabilities. Moreover, IT capabilities can enhance supplier performance through improving international KAM capabilities.

Abstract

The main argument of this paper is that the accounting profession in Canada exercises hegemonic leadership over the development of tax education in terms of cadence and direction of reforms. To support this argument, the paper uses the development of the microeconomic approach to teaching taxation and the correlation between the numbers of tax courses taught in undergraduate programs and exemptions provided by the provincial institutes of the Canadian Chartered Accountants to students joining them. It uses arguments from institutional isomorphism to elucidate expected resistance to adopting new developments, such as the microeconomic approach, in the accounting field. The paper also builds on Gramsci’s theory of hegemony to imply that business schools have given their consent to the Canadian Institute of Chartered Accountants by closely linking their curriculum, at least the taxation courses, to that of the institute.

The purpose of this paper is to explore and evaluate the current legal position on the admissibility and exclusion of illegally obtained evidence in money laundering cases.

Abstract

Purpose

The purpose of this paper is to explore and evaluate the current legal position on the admissibility and exclusion of illegally obtained evidence in money laundering cases.

Design/methodology/approach

A thorough exploratory analytical analysis signifies that such illegally obtained evidence from money laundering offences is admissible, provided it does not undermine the administration of justice or the right to a fair trial.

Findings

By virtue of the lack of written or codified rules governing the admissibility and exclusion of illegally obtained evidence in cases involving money laundering, the rule of admissibility remains the primary foundational principle for the governance of the admissibility and exclusion of illegally obtained evidence in money laundering cases.

Originality/value

The Malaysian Criminal Justice System has historically relied on the long-standing admissibility principles to admit and exclude illegally obtained evidence. For decades, courts have used their discretion to admit illegally obtained evidence based on the relevancy test, and they have further demonstrated to use the same discretion to exclude gravely prejudicial evidence. Evidence obtained illegally but if relevant to the matter in issue is deemed admissible. Evidence derived from an act associated with unlawful activities or a predicate offence in money laundering may be obtained illegally, which may influence the prosecution case and conversely, defend the accused’s rights to a fair trial.

Abstract

Purpose

The purpose of the paper is to emphasize the performance benefits of a long-term innovation and value creation perspective. This paper responds to the recent concept of the imagination premium method for valuing companies. It offers four key takeaways to create a long-term innovation-focused orientation for future value creation.

Design/methodology/approach

The research is based on both consulting experience and insight from several studies of executives that were supported by the U.S. Conference Board.

Findings

The research differentiates how high versus low innovators create long-term perspectives and value. High innovators have explicit processes that support innovation, leadership that focuses on long-term performance, resources committed to long-term projects and innovation and knowledge management systems that transfer knowledge throughout the organization.

Research limitations/implications

The research offers strategic directives aimed at creating long-term value but acknowledges that there are other means to accomplish such objectives.

Practical implications

This paper offers strategies for executives to create an innovation-focused organizational culture that drives lasting long-term value.

Social implications

Focusing on long-term innovation prioritizes larger social, environmental and business objectives over superficial short-term stock price changes, leading to greater value-creation.

Originality/value

This paper advocates that leadership play the long game and adopt a longer-term view of innovation due to its long-term competitive, employee engagement, sustainability and performance benefits.
