With the rapid technological advancements, E-commerce deliveries in Sri Lanka have been flourishing tremendously. However, payments have still been identified as one of the main obstacles to the developments of the E-commerce sector. The Cash on Delivery (COD) method has played a significant role in driving the growth of the E-commerce industry and accounts for more than 60% of all E-commerce transactions in Sri Lanka. Although COD is so important, many companies still waver with its processes as it has become a notoriously problematic area in terms of on-time and successful deliveries. Hence, the purpose of this study was to investigate the critical factors influencing online customers' preference of cash on the delivery method to provide insights into the management of E-commerce and logistics industries on the usage of appropriate payment methods for E-commerce transactions. This empirical study is based on the primary data obtained through a survey conducted among Sri Lankan online customers. The data were analyzed using the Partial Least Squares–Structural Equation Modelling technique. Consequently, 'Sri Lankan origin of the online seller,' 'Selling specialized products by the online seller,' 'Availability of wide choice of payment methods,' 'Offering a wide assortment of foreign products by the online seller,' 'Lack of trust on online payments' has been identified as the critical factors influencing Sri Lankan online customers' preference of cash on delivery method.

PurposeThe image of the construction industry in China, as in many other countries, is tarnished by its poor safety record. With the rapid development of subway systems in Chinese urban areas, construction workers are being exposed to new risks which are poorly understood and managed. Subway construction projects are large scale and scattered over many construction sites, and involve numerous stakeholders and sophisticated technologies in challenging underground environments. Accident rates are high and have significant economic and social consequences for the firms and people involved. Addressing the gap in research about the safety risk in these projects, the purpose of this paper is to advance understanding of the factors influencing the safety of Chinese subway construction projects with the overall objective of reducing accident rates.Design/methodology/approachA survey was conducted with 399 subway construction professionals across five stakeholder groups. Follow-up interviews were also conducted with five experienced experts in safety management on subway projects to validate the results.FindingsIt was found that the eight most critical factors perceived by stakeholders to influence safety risks on Chinese subway projects are: project management team; contractor-related factors; site underground environment; safety protection during the use of machines; safety management investment; site construction monitoring and measurement; hazard identification and communication; and use of machines in all stages. This indicates that in allocating limited project resources to improve the safety of subway projects, managers should focus on: developing safety knowledge and positive attitudes in leadership teams; formulating effective risk management systems to identify, assess, mitigate, measure and monitor safety risks on site; improving communications with stakeholders about these risks and effectively managing plant, equipment and machinery.Originality/valueThis research contributes a new multi-stakeholder perspective to the lack of safety research in Chinese subway construction projects. The research findings provide important new insights for policymakers and managers in improving safety outcomes on these major projects, producing potentially significant social and economic benefits for society and the construction industry.

The problem of resource allocation in the construction industry is a global phenomenon. Resource allocation plays an important role in Indian construction projects. The effective resource management is a prerequisite for project success. This paper aims to identify the critical factors that influence the resource allocation in Indian construction projects in private and public sectors. From extensive literature survey and based on experts’ opinion, forty four factors influencing resource allocation in Indian construction industry were identified. For the quantitative confirmation of the effectiveness of factors influencing resource allocation during the construction stage of a project, a questionnaire survey was conducted with construction professionals like clients, consultants and contractors. Subsequently the collected data was analyzed using the descriptive statistical method and the factors were measured and ranked under each group with Impact index. The findings reveal that the eleven top most critical factors such as materials selection and changes in types and specifications during construction, improper maintenance of equipment, shortage in construction materials, financing between the owner and contractor, force majeure (Fire, Wind damage, Hurricane, Flood), shortage of labours , poor procurement of materials, skill of labours, available of equipment and poor quality of materials. Results show that there is relatively highest agreement between contractor and consultant of about 66.7%. The resources like manpower, materials and equipment related factors are having a total contribution of about 60% and other groups are having of about 40% in resource allocation. However this paper presents recommendations for a better resource management techniques and procedures which can be adopted during conceptual , detailed planning and execution phases of the construction project.

Purpose The purpose of this study is to investigate and rank the critical factors influencing the bid/no bid criteria and their importance in the Australian construction industry. Design/methodology/approach The research study has been undertaken by conducting an extensive literature review on bid/no bid decision-making criteria. As a result, the researchers identified 26 most common bid/no bid decision-making criteria that are accordingly grouped into five distinct categories, namely, “project”, “market”,“contractor”, “client” and “contract”. The literature review was followed by a national survey that was designed and utilised by the researchers to collect data for this purpose. The survey was sent to potential 450 Australian construction companies in various locations and responses were received from 81 Australian construction companies. Response data were subjected to descriptive and inferential statistics. Kruskal Wallis one-way analysis of variance (ANOVA) was applied to detect significant differences between the mean score grouped according to the organisation size (contract value). Findings The descriptive and empirical analysis demonstrated a disparity of ranking of the 26 bid/no bid criteria factors among the groups; however no statistically significant differences among the 26 bid/no criteria factors despite the absolute differences in the rankings and mean scores in the following four factors: (1) “bidding condition”, (2) “strength/weaknesses”, (3) “contract payment terms” and (4) “number of competitors/bidders”. Based on the overall sample, the highly ranked four factors were “client financial capability”, “project risk”, “project future benefits and profitability” and “number of competitors/bidders”. The following were the least ranked: “contractors’ financial situation”, “project duration” and “contractors’ material availability”. “Client financial capability”and “project risk” were jointly ranked as the most important by large, whereas “client financial capability” was also rated highly for smaller Australian construction contractors (ACCs). The medium ACCs had “project risk”as highly ranked. Research limitations The majority of the participants were small construction contractors in Australia. The reason is that the researchers were not aware of the contractors’ size prior to inviting them for participation in the research study. Second, the findings may not generalise to other industries or to organisations operating in other countries. Practical implications The identified “bid/no bid criteria” increase the awareness of existing decision-making practices and play a critical role in the future decisions of the construction companies, where decision makers need to evaluate the next opportunities encountered. Furthermore, knowledge and possession of these identified “bid/no bid” criteria would enable contractors to select a project with a higher probability of success in the future, which will accordingly result in long-term financial benefits and higher performance. Finally, the awareness of these factors could contribute to changing the contractor’s behaviours when bidding in a competitive environment or market conditions. Originality/value The study contributes to the body of knowledge on tendering and bidding practices among contractors in Australia, an area previously under explored. Second, this study provides some insights on the factors influencing the bid/no bid decisions among the ACCs.

The infectious disease COVID-19 has swept across the world in 2020, and it continues to cause massive losses of life and severe economic problems in all countries. Providing emergency supplies such as protective medical equipment and materials required to secure people’s livelihood is thus currently prioritized by governments. Establishing a reliable emergency logistics system is critical in this regard. This paper used the Delphi method to design a formal decision structure to assess emergency logistics system reliability (ELSR) by obtaining a consensus from a panel of experts. Assessing ELSR is a typical multiple-attribute decision making (MADM) problem, and the related MADM methods are usually on the basis of symmetry principles. A hybrid MADM model, called the Decision Making Trial and Evaluation Laboratory (DEMATEL)-based Analytical Network Process (D-ANP), was developed to identify the critical factors influencing ELSR. An analysis of empirical evidence showed that the emergency logistics command and coordination system and the emergency material supply system play important roles in ELSR, while the emergency logistics transportation and distribution system and the emergency information system are not so important. This conclusion is different from previous research about traditional disaster emergency logistics. Moreover, the cause–effect relationships among the key factors indicated that the system of command and coordination for emergency logistics and the supply system for emergency materials should be improved. Accordingly, effective suggestions for emergency logistics services for epidemic prevention are provided in this paper. The main contributions of this paper are (1) establishing a comprehensive and systematic evaluating index of ELSR for epidemic prevention; (2) employing a kind of structured, namely D-ANP, to identify the critical factors with non-commensurable and conflicting (competing) characteristics; and (3) comparing the differences of reliable criteria between the emergency logistics of epidemic prevention and the traditional disaster emergency logistics.

To date there has been a theoretical and empirical gap in workplace-centered health promotion research—particularly as it applies to blue-collar men’s diets. To begin addressing the paucity of research, five qualitative focus groups ( N = 53) were conducted in Australian training colleges to explore the dietary behaviors of apprentices. Thematic analysis was used by the researcher who concludes that although some apprentices were health conscious and attempted to eat healthy foods, many had diets high in saturated fats and sugar. These types of diets are associated with increased risks for developing chronic disease and are associated with decreased life expectancy. As such it poses a serious challenge for health promoters. Apprentices’ dietary practices were also found to be moderated by convenience, availability, and cost of foods in their environment. Their nutritional beliefs, significant others, colleagues in the workplace, and their body image also influence their food choices.
