The Impact

Purpose – Asset management has recently gained significance due to emerging business models such as Product Service Systems where the sale of asset use, rather than the sale of the asset itself, is applied. This leaves the responsibility of the maintenance tasks to fall on the shoulders of the manufacturer/supplier to provide high asset availability. The use of asset monitoring assists in providing high availability but the level of monitoring and maintenance needs to be assessed for cost effectiveness. There is a lack of available tools and understanding of their value in assessing monitoring levels. The paper aims to discuss these issues. Design/methodology/approach – This research aims to develop a dynamic modelling approach using Discrete Event Simulation (DES) to assess such maintenance systems in order to provide a better understanding of the behaviour of complex maintenance operations. Interviews were conducted and literature was analysed to gather modelling requirements. Generic models were created, followed by simulation models, to examine how maintenance operation systems behave regarding different levels of asset monitoring. Findings – This research indicates that DES discerns varying levels of complexity of maintenance operations but that more sophisticated asset monitoring levels will not necessarily result in a higher asset performance. The paper shows that it is possible to assess the impact of monitoring levels as well as make other changes to system operation that may be more or less effective. Practical implications – The proposed tool supports the maintenance operations decision makers to select the appropriate asset monitoring level that suits their operational needs. Originality/value – A novel DES approach was developed to assess asset monitoring levels for maintenance operations. In applying this quantitative approach, it was demonstrated that higher asset monitoring levels do not necessarily result in higher asset availability. The work provides a means of evaluating the constraints in the system that an asset is part of rather than focusing on the asset in isolation.

Purpose This paper aims to investigate how and to what extent the Fijian sustainable banking regulations or guidelines are designed, communicated, implemented and monitored within the financial system in Fiji. A scorecard is introduced for this purpose to assess the effectiveness of Fiji’s financial battle against climate change (FBACC). Design/methodology/approach This study uses a mixed-method methodology. Data were collected mainly from a survey and supplemented by interviews, observations and documents. The scorecard was developed by building on existing two theoretical frameworks, namely, the Sustainable Banking Assessment and Climate Change Governance Index, to make them more appropriate and practically applicable to less developed financial systems in emerging economies such as Fiji. This FBACC scorecard consists of four perspectives, eight critical factors and 24 criteria. Findings The results show that the overall FBACC score averages 40.75%, and all the perspectives scored below 50%, the benchmark. Only the CF “policy” scored 54.25% because of a high positive response of 82.3% for the “political leadership” criterion. The relative contributions of each perspective in constructing the overall score are distributed as 28%, 25%, 24% and 23% among planning, action, accountability and control, respectively. Research limitations/implications These results were complemented by the information shared during the interviews and confirmed that the existing political initiatives need to be effectively communicated and/or implemented in the financial system by the regulatory agencies. Practical implications This FBACC scorecard can be applied to other underdeveloped systems in emerging countries to assess the effectiveness of the sustainable banking regulations and/or guidelines in those countries in relation to the FBACC. It can also be applied to individual firms to assess their contribution to the FBACC. Originality/value To the authors’ best knowledge, this might be the first study in Fiji that considers the impact of climate-related financial risk on the Fijian financial system.

Purpose The purpose of this paper is to explore certain resources, capabilities and competencies needed to improve the performance of physical asset management (PAM). Design/methodology/approach The analytic hierarchy process (AHP) is used to select and prioritize the most appropriate factors for improving performance. A multi-criteria approach is used to analyze and compare the importance of 6 main criteria and 18 subcriteria identified from a survey of relevant literature. Findings The study revealed that not all factors are viewed as having equal importance in improving PAM performance, as three of the main factors attained greater importance among the six factors. Research limitations/implications This study explored the factors required for managing assets only within the third stage of asset lifecycle, that is, the utilization stage. It is recommended that future studies be conducted in such a way as to determine the importance of similar factors in the other stages of the asset lifecycle, or to identify new factors and add new criteria. Practical implications Knowledge of the differential impacts of the factors on the performance of PAM can impact asset managers and decision makers in their allocation of resources and focus their work on the highest-ranked rather than the lowest-ranked factors. Also, AHP used provides an effective mean for asset managers to identify priorities among decision criteria in their organization. Originality/value To date, no study has explored the impact of six combined factors on the performance of PAM. Previous studies have found that these factors each had equal importance. However, their relative ranking in practice and when they appear together have remained unrecognized.

The same principles that have made other skilled-trade-based industries more efficient are being deployed in construction through Industrialization, which requires understanding skilled trade work and segregating/externalizing the work from the jobsite. The construction industry still relies heavily on skilled trades and their tacit knowledge, while most of the information available at the points of installation is not passed on. A significant increase of work externalization requires a measuring and tracking method that can: 1) tap into this tacit knowledge as the basis for work planning and control; and 2) understand, quantify, and minimize the manipulation effort done onsite for the prefabricated assemblies. As such, this paper presents a planning and control framework for industrialized construction operations that integrates information entropy and the novel concept of work manipulations to monitor and measure the expected performance outcomes, in a more sophisticated approach beyond measuring äóìhoursäó� and äóìquantitiesäó� of the work. The development of the proposed framework is based on the analysis of a set of case studies that illustrate the impact of information predictability manipulation strategies on construction prefabrication decisions.

The Impact

Purpose The purpose of this paper is to identify the factors influencing the citizens to use robots that would improve the quality of life of the citizens. Design/methodology/approach With the help of different adoption theories and models and with the support of background studies, some hypotheses have been formulated and a conceptual model has been developed with the consideration of the impact of artificial intelligence regulation (IAR) that controls the use of robots as a moderator. The model has been validated and the hypotheses have been tested by statistical analysis with the help of survey works involving consideration of feedbacks from 503 usable respondents. Findings The study reveals that the use of robots by the citizens would appreciably increase if government imposes strict artificial intelligence (AI) regulatory control concerning the use of robots, and in that case, it appears that the use of robots would improve the quality of life of the citizens. Research limitations/implications The duly validated model would help the authority to appropriately nurse and nurture the factors such as ethical dilemma, perceived risks and control beliefs for enhancing the intention of the citizens to use robots for many purposes including domestic usage in the context of appropriate restrictions imposed through AI regulation. Such use of robots would eventually improve the quality of life. Originality/value There are a few studies covering analysis of IAR as a moderator on the linkages of the predictors with the intention of the citizens to use robots. In this context, this study is claimed to have offered a novel contribution.

Purpose The purpose of this paper is to examine the development of family protective factors in participants of Help Me Grow Utah (HMGU), a community-based system that promotes child development, seeks early detection of developmental delays, and links families to services. Design/methodology/approach In this paper, standard quasi-experimental survey design was utilized. HMGU and control group participants completed the FRIENDS Protective Factors Survey, which was slightly modified into a retrospective pre-test and post-test format to address previous survey concerns of response-shift bias, self-serving assessments, and family maturation. Participants were asked to respond to ten questions at present and then again from the perspective of two years previous. Findings Participants in HMGU had statistically significant increases in protective factor scores in all but one subscale, with dramatic increases in two subscale questions on knowledge of parenting and child development. Control group scores statistically increased in four subscales, albeit at lower rates than HMGU participants. Interestingly, control group scores on two subscale questions relating to child maltreatment risk were significantly lower on post-tests as compared to their retrospective pre-test scores. Research limitations/implications Participants in HMGU clearly increased in the development of protective factors. Replication of this study is recommended and the need for a control group in protective factor studies is imperative. Practical implications Findings from this study suggest that child services focused on enhancing knowledge of parenting and child development might also expect to improve protective factors. One-on-one care coordination with families seems particularly effective. The findings might also benefit other social programs as they utilize retrospective pre-test, post-test, and control groups in their evaluations. Originality/value HMGU is the first affiliate to utilize retrospective pre-test/post-test methodology, which can overcome confounding results attributable to response-shift bias. Also, the use of a control group affords inclusion of natural maturation in considering findings.

The Impact

PurposeThe aim of this paper is to quantify the impact of transboundary air pollutants, particularly those related to urban traffic, on health outcomes. The importance of focusing on the health implications of transboundary pollution is due to the fact that these emissions originate from another jurisdiction, thus constituting international negative externalities. Thus, by isolating and quantifying the impact of these transboundary air pollutants on domestic health outcomes, the authors can understand more clearly the extent of these externalities, identify their ramifications for health and emphasise the importance of cross-country cooperation in the fight against air pollution.Design/methodology/approachThe authors employ panel data regression analysis to look at the relationship between emissions of transboundary air pollution and mortality rates from various respiratory diseases among a sample of 40 European countries, over the period 2003–2014. In turn, the authors use annual data on transboundary emissions of sulphur oxides (SOx), nitrogen oxides (NOx) and fine particulate matter (PM2.5), together with detailed data on the per capita incidence of various respiratory diseases, including lung cancer, asthma and chronic obstructive pulmonary disease (COPD). The authors consider a number of different regression equation specifications and control for potential confounders like the quality of healthcare and economic prosperity within each country.FindingsThe results show that transboundary emissions of PM2.5 are positively and significantly related to mortality rates from asthma in our sample of countries. Quantitatively, a 10% increase in PM2.5 transboundary emissions per capita from neighbouring countries is associated with a 1.4% increase in the asthma mortality rate within the recipient country or roughly 200 deaths by asthma per year across our sample.Originality/valueThese findings have important policy implications for cross-country cooperation and regulation in the field of pollution abatement and control, particularly since all the countries under consideration form a part of the UN's Convention on Long-Range Transboundary Air Pollution (CLRTAP), a transnational cooperative agreement aimed at curtailing such pollutants on an international level.

Purpose The purpose of this paper is to analyze the effect of management accounting and control systems (MACS) on environmental innovation practices and operational performance. Specifically, this study relies on Simons’ levers of control (LOC) framework to investigate how managers implement environmental innovation practices. This paper hypothesizes that a forward-looking use of MACS (i.e. interactive use) triggers the implementation of environmental innovation practices, resulting in higher operational performance. Furthermore, the authors argue that the monitoring role of MACS (i.e. diagnostic use) combined with environmental training improves the effect of environmental innovation practices on operational performance. Design/methodology/approach Hypotheses are examined through a questionnaire survey. The analyses are based on responses in an empirical study from 89 Brazilian hotels. Findings Empirical findings from a hierarchical moderated regression analysis support the hypothesized links. Originality/value This study contributes to the environmental management and management control literature by providing novel evidence on the roles MACS play in the field of sustainable development. Based on the LOC framework, the authors shed light on the understanding of how managers introduce and monitor environmental innovation practices, as well as also outlining the key effects of environmental training in enabling the novel abilities of managers and employees to better understand environmental data and identify novel potential environmentally friendly solutions in the case of deviations. This paper also adds to Wijethilake et al. (2017), providing new empirical evidence on how firms design, implement and use MACS that capture institutional pressures for sustainability from multiple stakeholders.

PurposeEmployee engagement has been directly linked to organizational outcomes, and at present, improving employee engagement has increasingly been a main focus for organizations. However, studies evaluating the impact of storytelling interventions on increasing the level of employee engagement are limited. Storytelling is one of the intervention methods that can provide cognitive stimulus to employees, which in turn could change their attitudes toward work including employee engagement. The purpose of this study is to determine the effectiveness of storytelling as an intervention tool for increasing employee engagement in one of the state-owned enterprises (SOEs) in West Java, Indonesia.Design/methodology/approachThis study uses a quantitative method. Employees from a West Java branch of large SOEs were randomly assigned into experimental and control groups. The research design used a pretest and a post-test with an expressive writing method to identify the extent of employee engagement by comparing participant groups and measuring the increase of employee engagement as a result of the storytelling intervention. The experimental group participated in three storytelling sessions that had been set up by panels of experts, while the control group was not given any treatment. The expressive writing analysis was conducted using software that has been developed and tested for validity and reliability. Furthermore, statistical analysis was used to test the results of expressive writing scoring to determine the impact of storytelling interventions.FindingsDirect storytelling is proven to be one of the most effective methods of increasing employee engagement in one of the SOEs in the West Java region. The results of this study showed that there were differences between the experiment and control groups after experiencing a direct storytelling intervention where there was a significant increase in the dimensions of employee engagement. Participants in experimental group had higher scores than participants in control group in most of the employee engagement dimensions. Additionally, expressive writing methods are also proven to be able to provide a stimulus for employees in expressing thoughts, perceptions and motivations for employee engagement in the company.Research limitations/implicationsAs direct storytelling has not been frequently used, especially to improve employee engagement, more studies should be conducted in various settings, with different measurement tools, and in a more controlled environment to confirm the effects of the intervention.Practical implicationsThis paper provides insight into how companies can use direct storytelling to improve the dimensions of employee engagement. Additionally, this research can also be used as a reference by companies in Indonesia, especially SOEs, for applying the same method in an effort to improve work-related attitudes, such as employee satisfaction and organizational commitment.Social implicationsThis study raises social implications in which employees enthusiasm increases in improving personal relationships between employees and storytellers, who are middle or upper management employees. In addition, employees also more appreciate their struggles when starting their careers, so they care more about increasing their role and involvement in the company.Originality/valueThis paper provides resources and information for companies and organizations to improve employee engagement through the implementation of direct storytelling. The focus of this paper is to gain information on the role of direct storytelling in improving employee engagement within a company or organization.

Purpose The purpose of this paper is to suggest a strong structuration-based framework for the study of management accounting change. Design/methodology/approach A retrospective field study was designed to investigate the impact of the 2008 financial crisis on budgeting and control practices of Greek hospitality organisations. Conduct analysis addresses agents’ perceptions of the changes upon themselves. Context analysis explores the changing context, and how the agents modified their in-situ control structures accordingly. The framework is demonstrated through one case study. Findings The agents in the case, triggered by the crisis, gradually come to criticise the way they practice budgeting. The first response is to practice budgeting more normatively, but later they criticise and modify these norms. As their formal mentalities co-mediated action, variance management became proactive rather than reactive. Variations in the ways agents draw upon structures – unreflectively or critically – and on how they act to reproduce structures – routinely or strategically – characterise change in management accounting practice. Agents’ reasoning and conduct leading to action is local, and these local changes in conduct and context are significant in understanding management accounting change. Originality/value This framework for studying management accounting change balances structural conditions of action, with action and interaction. It can be used to study how, why, and by whom institutionalised management accounting practices may change.
