Abstract

Purpose

The purpose of this paper is to present the findings of the MobiCert project, which utilises mobile commerce technology to enhance information access and provision for organic primary producers, so as to improve their integration into the grocery supply chain. This paper is a precursor to developing a mobile solution for both conventional and organic primary producers across Australia and potentially other countries.

Design/methodology/approach

The rapid appraisal research approach is selected for this research paper as it is particularly suited for gathering fast, rich and deep data in rural and remote areas.

Findings

This paper discusses the development of a mobile information community prototype for organic primary producers in rural South Australia which provides information access and data gathering functionalities through the use of a PDA/Smart phone. The Rural Area Technology Acceptance and Diffusion of Innovation Model is developed to investigate acceptance of mobile technology and the likely diffusion of this innovation in rural areas. It offers a theoretical underpinning for the project, and illustrates how this paper contributes to the management/marketing literature.

Originality/value

This research project is of considerable value for primary producers in rural and remote areas, because it enables and enhances their access to and provision of information – a critical factor for timely and effective access to the grocery supply chain.

Abstract

Purpose

The purpose of this study is therefore to detail an additive manufacturing process for printing TiD parts for implant applications. Titanium–diamond (TiD) is a new composite that provides biocompatible three-dimensional multimaterial structures. Thus, the authors report a powder-deposition and print optimization strategy to overcome the dual-functionality gap by printing bulk TiD parts. However, despite favorable customization outcomes, relatively few additive manufacturing (AM) feedstock powders offer the biocompatibility required for medical implant and device technologies.

Design/methodology/approach

AM offers a platform to fabricate customized patient-specific parts. Developing feedstock that can be 3D printed into specific 3D structures while providing a favorable interface with the human tissue remains a challenge. Using laser metal deposition, feedstock powder comprising diamond and titanium was co-printed into TiD parts for mechanical testing to determine optimal manufacturing parameters.

Findings

TiD parts were fabricated comprising 30% and 50% diamond. The composite powder had a Hausner ratio of 1.13 and 1.21 for 30% and 50% TiD, respectively. The flow analysis (Carney flow) for TiD 30% and 50% was 7.53 and 5.15 g/s. The authors report that the printing-specific conditions significantly affect the integrity of the printed part and thus provide the optimal manufacturing parameters for structural integrity as determined by micro-computed tomography, nanoindentation and biocompatibility of TiD parts. The hardness, ultimate tensile strength and yield strength for TiD are 4–6 GPa (depending on build position), 426 MPa and 375 MPa, respectively. Furthermore, the authors show that increasing diamond composition to 30% results in higher osteoblast viability and lower bacteria count than titanium.

Originality/value

In this study, the authors provide a clear strategy to manufacture TiD parts with high integrity, performance and biocompatibility, expanding the material feedstock library and paving the way to customized diamond implants. Diamond is showing strong potential as a biomedical material; however, upscale is limited by conventional techniques. By optimizing AM as the avenue to make complex shapes, the authors open up the possibility of patient-specific diamond implant solutions.

Abstract

Purpose

Travel destinations worldwide are seeking smart ways to reduce the negative impact of tourism, and the public bike rental service (PBRS) is one of them. To investigate the usage intention of this service among visitors, the author of this research employs an integrated approach consisting of two psychological frameworks: the Norm Activation Model (NAM) and the Technology Acceptance Model (TAM).

Design/methodology/approach

The integrated NAM-TAM model is implemented to conduct a survey (sample n = 777) with visitors to Hanoi, Danang, and Ho Chi Minh City regarding the factors underlying their intentions to continue using the PBRS TNGo.

Findings

Structural equation models suggested that: (1) the NAM-TAM can explain behavioural intention to use a smart PBRS. Perceived Usefulness (PU), Perceived Ease of Use (PE), and Awareness of Consequences (AC) have positive and significant impacts on Attitude Towards Using (AT) and, thus, on Behavioural Intention to Use (BI). Also, Personal Norms (PN) positively influence BI. (2) Among the four independent variables, tourists' AC produces the most potent effect on the intention to continue using a PBRS.

Research limitations/implications

This study can start a new research direction of combining the NAM with other theoretical frameworks to explain customer behaviour in the field of sustainable tourism practices. Future research should explore the proposed model based on comparisons of different tourists’ backgrounds, including nationality, length of stay, spending level, visiting purpose, etc.

Practical implications

This research provides strategic implications for destination management organisations in boosting the use of PBRS amongst tourists, contributing to the environmental sustainability targets of the tourism industry.

Originality/value

This study responds to the existing gap by examining both functional value (indicated by PU and PE) and perceived environmental/social value (proxied by AC) in forming tourists’ attitudes towards PBRS and their usage intention. Our study, therefore, actively contributes to the research stream of tourist behaviour in the field of sustainable tourism practices from the altruistic behavioural perspective.

Abstract

Purpose

This study aims to identify and prioritize barriers to corporate social responsibility (CSR) in the construction sector.

Design/methodology/approach

A literature review was first conducted to identify barriers to CSR performance. After that, construction professionals were invited to validate the appropriateness of the obstacles. The discussion allowed the establishment of a list of barriers to CSR performance and their corresponding categories. Data collected from the survey were then analyzed to prioritize the importance of these barriers by the fuzzy DEMATEL-based ANP (DANP) technique.

Findings

The findings presented 16 barriers to CSR, which were categorized into four clusters. The fuzzy DANP analysis showed that strategic vision is the most crucial cluster, followed by the measurement system, stakeholder perspective and scarce resources. Among the sixteen barriers examined, lack of awareness, knowledge and information of CSR; low priority of CSR; lack of metrics to quantify CSR benefits; lack of guidelines and coherent strategies; and lack of CSR enforcement mechanism are the five most crucial barriers.

Originality/value

This study is one of the first that proposes a comprehensive model to prioritize barriers to CSR performance of contractors considering their interrelationships. It provides construction stakeholders with a framework for understanding the linkage between the barriers and CSR framework under the umbrella of stakeholder theory. Thus, the findings might assist construction practitioners and academics in fostering the success of CSR implementation.

Abstract

Purpose

The theoretical and empirical relationships between corporate social responsibility (CSR) and corporate financial performance are not without controversy. Yet, CSR activities are increasingly undertaken by a large number of firms, not only in developed countries but also in emerging countries. This paper aims to investigate the moderating effect of different aspects of corporate governance, which are foreign and state ownership, board size and board independence, on the relationship between CSR and financial performance.

Design/methodology/approach

A sample of Vietnamese listed firms is analyzed. Robust regression analysis is performed using ordinary least squares as well as fixed-effects and two-stage least squares model.

Findings

Ordinary least squares regression results show that CSR activities affect the financial performance of firms positively. Furthermore, corporate governance features like foreign ownership, board size and board independence strengthen the positive relationship between CSR and financial performance, but there is no such impact of state ownership.

Originality/value

Previous studies mostly investigate the direct effect of CSR on financial performance. A few studies examine the moderating effect of corporate governance, which is ownership concentration and board gender diversity. As an emerging country, Vietnam has some specific characteristics on corporate governance. This paper contributes by investigating the moderating effect of few major aspects of corporate governance, which are foreign and state ownership, board size and board independence.

Abstract

Purpose

This study aims to investigate the association between corporate governance (CG) and the corporate social responsibility (CSR) information disclosure as well as the moderating role of state-ownership between CG and CSR disclosure.

Design/methodology/approach

To examine the relationship between CG and CSR disclosure, this study used the feasible general least squares and generalized method of moments method on a sample of 165 non-financial quoted companies over the 2015–2018 period, which account for about three-fourths of the Vietnamese stock exchange.

Findings

The findings suggest that enterprises with smaller board size consisting mainly of independent directors have a higher CSR disclosure level. Moreover, when the chief executive officer is concurrently the chairman of the board, the level of CSR disclosure falls. Additionally, the moderating role of state ownership enhances CSR disclosure.

Research limitations/implications

The empirical results of this study form a solid foundation for policymakers and other stakeholders’ decisions in investing or establishing policies.

Originality/value

This study provides empirical evidence on the relationship between CG and CSR disclosure in Vietnam – a developing country with no legal requirement on CSR disclosure. Moreover, this study emphasizes the moderating role of state ownership between CG and CSR disclosure, which clarifies the role of state ownership in establishing CG mechanisms.

Abstract

Purpose

In order to improve the safety of seafood in the domestic seafood distribution chains (DSDCs) in Vietnam, a better understanding of current hygiene and practices compliance with government regulations is needed. The paper aims to discuss this issue.

Design/methodology/approach

Infrastructure conditions and documents related to hygiene procedures of 50 trading places were evaluated using checklists. The hygiene handling practices of 135 fish distributors were also observed by using notational analysis methods. This notational analysis method focused on actions related to microbiological contamination in terms of hand washing or glove changing and the cleaning and sanitising of tools and equipment. Additionally, microbiological quality of 135 samples of raw finfish at points along distribution chains was compared with national standards.

Findings

The results indicated that all trading places could be classified as non-compliant or seriously non-compliant with the regulations. The practices of fish distributors were also assessed to be at high risk for contamination of raw fish. The findings showed that approximately 42 and 39 per cent of samples from fishing ports and fish markets, respectively were classified as unacceptable according to the microbiological standards of Vietnam.

Research limitations/implications

The present study is limited to research only from fish landing at fishing ports to the distribution to consumers at retail markets.

Originality/value

Recommendations for improving food safety in the DSDCs in Vietnam have been developed from the findings of this study and are provided. However, due to similarities with fish distribution chains in other countries, these recommendations may have broader application.
