Abstract

Purpose

The purpose of this paper is to identify risk patterns of road and bridge projects in Vietnam, where the construction market is emerging but attractive to construction organizations, especially foreign companies.

Design/methodology/approach

Using a questionnaire, experienced practitioners of various contractors were interviewed to collect risk-related data in terms of actual likelihood and impact from road and bridge construction projects in Vietnam. Using the collected data of actual likelihood and impact, the specific probability and impact of risk factors were determined for different types of road and bridge projects, including small and medium type, big type, government-funding type, and other-funding type (e.g. official development assistance funds, public-private partnership).

Findings

The results of analysis indicate the specific probability and impact of risk factors in four risk themes, including contractor-related, project-related, owner-related, and external risks. Actual risk patterns for different types of road and bridge projects in Vietnam were identified.

Practical implications

The identification of actual risk patterns could help practitioners to know which risk factors are severe in frequency and/or impact. Hence, they could establish proper strategies to manage risk-related problems of road and bridge projects, in which they are directly involved.

Originality/value

The findings of this study could provide construction companies, especially foreign companies, with a better understanding of real risk panorama in Vietnamese road and bridge construction. Hence, they could make effective improvements on risk management of road and bridge projects in Vietnam.

Abstract

Purpose

Time is an important factor in any project, especially in construction projects. Although using detailed scheduling techniques is unavoidable, a model to predict or benchmark time performance has interested many researchers. For an exploratory purpose, this paper aims to investigate the time‐cost relationship proposed by Bromilow with data from construction projects in Korea.

Design/methodology/approach

The data are collected from 34 historical building projects in Korea. Construction cost is adjusted using a building price index. Analysis is carried out on variety of project characteristics.

Findings

It is shown that a time‐cost relationship is applicable to the Korean construction industry. Further analysis indicates that the original Bromilow time‐cost model is not the best fit regression form, and alternative models are proposed.

Research limitations/implications

The data are limited to a small sample of 34 building projects. This limitation arises because of the data collection approach, which is direct contact with historical project documents supplied by construction firms.

Originality/value

Models from this study can serve as a reference tool for practitioners in the early stages of building projects in Korea. The results from this study are not intended to reject or replace detailed construction scheduling techniques.

Abstract

Purpose

The purpose of this article is to identify and explore pertinent conflicting factors in construction projects; which would be helpful for project planners and implementers in assessing and taking proactive measures for reducing the adverse effect of conflict.

Design/methodology/approach

To achieve the study objectives, a 43‐item questionnaire survey in a five‐point Likert scale was carried out to collect professionals' experience on conflicting activities in Korean construction projects. Responses from 124 professionals working for owners, consultants and contractors were analyzed. Furthermore, ten face‐to face interviews were also carried out to ratify the findings from the field survey. Later, analytical hierarchical process method was employed to find out the importance weighting as well as responsible party for the perceived conflicts.

Findings

This study has found out six critical construction conflicting factors pertinent in Korean context. These factors with importance weighting are: differing site condition (24.1 percent), public interruption (22.5 percent), differences in change order evaluation (21 percent), design errors (17.1 percent), excessive contract quantities variation (8.2) and double meaning of specifications (7.1 percent). The study has revealed that owner (35.6 percent) and consultant (34.18 percent) are mostly responsible parties for conflicts in construction projects.

Originality/value

As the previous researches have been indicating increase in conflicts in construction field, this paper is very topical at the moment. This work has tried to explore the underlying problems of the construction field. The study provides field level experiences from which the inexperience construction site professionals could learn the instances of conflicts and not repeat the mistakes in their projects.

Abstract

The concept and practice of e-services has become essential in business transactions. Yet there are still many organizations that have not developed e-services optimally. This is especially relevant in the context of Indonesian Airline companies. Therefore, many airline customers in Indonesia are still in doubt about it, or even do not use it. To fill this gap, this study attempts to develop a model for e-services adoption and empirically examines the factors influencing the airlines customers in Indonesia in using e-services offered by the Indonesian airline companies. Taking six Indonesian airline companies as a case example, the study investigated the antecedents of e-services usage of Indonesian airlines. This study further examined the impacts of motivation on customers in using e-services in the Indonesian context. Another important aim of this study was to investigate how ages, experiences and geographical areas moderate effects of e-services usage.

The study adopts a positivist research paradigm with a two-phase sequential mixed method design involving qualitative and quantitative approaches. An initial research model was first developed based on an extensive literature review, by combining acceptance and use of information technology theories, expectancy theory and the inter-organizational system motivation models. A qualitative field study via semi-structured interviews was then conducted to explore the present state among 15 respondents. The results of the interviews were analysed using content analysis yielding the final model of e-services usage. Eighteen antecedent factors hypotheses and three moderating factors hypotheses and 52-item questionnaire were developed. A focus group discussion of five respondents and a pilot study of 59 respondents resulted in final version of the questionnaire.

In the second phase, the main survey was conducted nationally to collect the research data among Indonesian airline customers who had already used Indonesian airline e-services. A total of 819 valid questionnaires were obtained. The data was then analysed using a partial least square (PLS) based structural equation modelling (SEM) technique to produce the contributions of links in the e-services model (22% of all the variances in e-services usage, 37.8% in intention to use, 46.6% in motivation, 39.2% in outcome expectancy, and 37.7% in effort expectancy). Meanwhile, path coefficients and t-values demonstrated various different influences of antecedent factors towards e-services usage. Additionally, a multi-group analysis based on PLS is employed with mixed results. In the final findings, 14 hypotheses were supported and 7 hypotheses were not supported.

The major findings of this study have confirmed that motivation has the strongest contribution in e-services usage. In addition, motivation affects e-services usage both directly and indirectly through intention-to-use. This study provides contributions to the existing knowledge of e-services models, and practical applications of IT usage. Most importantly, an understanding of antecedents of e-services adoption will provide guidelines for stakeholders in developing better e-services and strategies in order to promote and encourage more customers to use e-services. Finally, the accomplishment of this study can be expanded through possible adaptations in other industries and other geographical contexts.

Abstract

The purpose of this article is to present an overview of the history and development of transaction log analysis (TLA) in library and information science research. Organizing a literature review of the first twenty‐five years of TLA poses some challenges and requires some decisions. The primary organizing principle could be a strict chronology of the published research, the research questions addressed, the automated information retrieval (IR) systems that generated the data, the results gained, or even the researchers themselves. The group of active transaction log analyzers remains fairly small in number, and researchers who use transaction logs tend to use this method more than once, so tracing the development and refinement of individuals' uses of the methodology could provide insight into the progress of the method as a whole. For example, if we examine how researchers like W. David Penniman, John Tolle, Christine Borgman, Ray Larson, and Micheline Hancock‐Beaulieu have modified their own understandings and applications of the method over time, we may get an accurate sense of the development of all applications.

Abstract

The Incheon Region has numerous assets that fall within a Pentaport model.' These include the Incheon International Airport, the Port of Incheon, a coastal industrial park, free economic zones, a leisure port, and Songdo new town designed to be the future Silicon Valley of Korea. This paper looks at how Northeast Asia trade flows between China and Korea might be enhanced by application of the Pentaport model in making the Incheon region a North East Asian Hub. It looks also at their trade and logistics systems as well as their water borne commerce. It proposes an integrated transportation system for the Yellow Sea Region being beneficial to the economies of the Northeast Asia. It also stresses that innovative technologies for ships, terminals and cargo handling systems should be introduced to develop a competitive short sea shipping system in the region and cooperation among the regional countries will be essential to achieve the final goal. The potential of methods of container shipping is discussed as it might apply to short sea shipping in the Yellow Sea Region that could greatly facilitate Incheon's situation with respect to the broader region in application of the Pentaport model.

Abstract

Purpose

Food waste is a systemic problem, with waste occurring at all stages in the supply chain and consumption process. There is a need to unpack which strategies, approaches and tools can be applied to reduce the amount of food wasted. Understanding the extent of social marketing principles used offers insights into the additional means that can be applied to increase voluntary behavioral change.

Design/methodology/approach

Following preferred reporting items for systematic reviews and meta-analyses guidelines, a systematic quantitative literature review was undertaken focused on outcome evaluation studies conducted since 2000. Six databases were examined, and cross rating was used to identify previous programs tackling food waste behavior at a household level. A total of 23 programs were analyzed against 8 social marketing components.

Findings

Overall, only 2 out of 23 food waste programs self-identified as social marketing programs. A lack of application of social marketing elements was observed across all studies, indicating a tendency to implement non-voluntary change approaches. The most commonly targeted behaviors were source-separation. Personal interaction involved the distribution of information in person (typically through door knocking). Personal interaction strategies were identified as the most effective program techniques. Program effectiveness was greater when the social marketing components of behavioral change, theory and marketing mix were used, indicating the potential for voluntary approaches to be applied more in the future.

Originality/value

To the best of the authors’ knowledge, the current study was the first systematic literature review to examine the extent of social marketing application in food waste programs reported in peer-reviewed academic literature using eight components of social marketing. The study revealed behavioral change was more likely when more social marketing components were used. Future research is recommended to consider the application of full range of social marketing elements to extend beyond involuntary approaches, which can be subjected to criticism from community.

Abstract

Purpose

Measuring service quality in online retail is critical. The purpose of this paper is to put in foreground key methodological issues of prevailing research related to scale development for the measurement of service quality in the context of online retail.

Design/methodology/approach

Content analysis of 30 research papers sourced from prestigious databases has been done to detect defects within research and sampling methods, survey administration, item generation and purification, dimensionality analysis, reliability and validity assessment. Also observations regarding dimensionality of online service quality constructs have been highlighted.

Findings

Study revealed deficiencies in sample size and composition, quantitative orientation in research methods, leniency in item generation/purification and negligent assessment of reliability and validity. It was found that e-service quality is multidimensional in nature and there is no consensus on number and nature of dimensions, although security/privacy, website design, reliability, responsiveness and information emerged as most cited dimensions. Electronic and traditional service quality dimensions displayed analogy in direct or adapted form.

Originality/value

This paper is first to highlight key methodological issues of prevailing research on e-service quality scale development in context of online retail. Implications for researchers and managers are summarized at the end of the study.

Abstract

Purpose

The study explores Degree Apprenticeship Identity (DAI) conceptualisation to enrich understanding to enhance work-integrated learning (WIL). Lived experiences of degree apprentices (DAs) are examined, and a model of DAI developed to support teaching and learning interventions on this relatively new and significant programme.

Design/methodology/approach

It draws pragmatically upon qualitative data from semi-structured interviews with Chartered Manager Degree Apprenticeship from diverse backgrounds in a higher education institutes (HEI). Data were explored abductively, using thematic analysis to investigate common patterns that influence identity; investigating personal experiences, socio-economic and cultural background, educational context and social interactions.

Findings

Influential themes surfaced, including pride in work, supporting others, sharing experiences and belonging, facilitating DAI model formation. The model illustrates that DAI is composed of existing personal, necessary professional and power of learning transformation through social identity by interventions that encourage peer engagement, group reflection and group-actualisation.

Research limitations/implications

As this is a small-scale exploratory study, it is not intended to be representative of wider populations, which results in generalisability of findings. Data were collected from a well-established closed cohort programme led by the researcher, previously programme director. Interviews generated a broad range of anecdotal evidence, surfacing valuable insights relating to DAI formation.

Practical implications

To enhance WIL, tutors can foster social interventions that encourage peer dialogue, heighten DAs sense of self as capable learners and increase confidence growth.

Originality/value

The research provides a DAI Model, a fresh approach to understanding ways to enhance WIL for DAs through a stronger focus on group identity through social interventions. This preliminary model presents an opportunity for further research; other apprenticeships, larger and/or open cohorts.
