Abstract

Turnaround maintenance (TAM) is an essential activity in process industry. It plays an important role in maintaining consistent productive capacity. It is a major project that requires sound planning, execution and control. In this paper guidelines for a structured approach for managing TAM is outlined and the current practice of TAM in petrochemical industry is assessed. The assessment of the current practice is conducted through a structured questionnaire that covers all the essential phases and activities of TAM. Suggestions for improving the practice of TAM are also provided in the paper. Practical implications. This paper provided a structured approach and guidelines for initiating, planning, executing and terminating TAM. The guidelines are expected to evolve into a manual that can be utilized by process industry for managing TAM.

Abstract

Smart card-based E-payment systems are receiving increasing attention as the number of implementations is witnessed on the rise globally. Understanding of user adoption behavior of E-payment systems that employ smart card technology becomes a research area that is of particular value and interest to both IS researchers and professionals. However, research interest focuses mostly on why a smart card-based E-payment system results in a failure or how the system could have grown into a success. This signals the fact that researchers have not had much opportunity to critically review a smart card-based E-payment system that has gained wide support and overcome the hurdle of critical mass adoption. The Octopus in Hong Kong has provided a rare opportunity for investigating smart card-based E-payment system because of its unprecedented success. This research seeks to thoroughly analyze the Octopus from technology adoption behavior perspectives.

Cultural impacts on adoption behavior are one of the key areas that this research posits to investigate. Since the present research is conducted in Hong Kong where a majority of population is Chinese ethnicity and yet is westernized in a number of aspects, assuming that users in Hong Kong are characterized by eastern or western culture is less useful. Explicit cultural characteristics at individual level are tapped into here instead of applying generalization of cultural beliefs to users to more accurately reflect cultural bias. In this vein, the technology acceptance model (TAM) is adapted, extended, and tested for its applicability cross-culturally in Hong Kong on the Octopus. Four cultural dimensions developed by Hofstede are included in this study, namely uncertainty avoidance, masculinity, individualism, and Confucian Dynamism (long-term orientation), to explore their influence on usage behavior through the mediation of perceived usefulness.

TAM is also integrated with the innovation diffusion theory (IDT) to borrow two constructs in relation to innovative characteristics, namely relative advantage and compatibility, in order to enhance the explanatory power of the proposed research model. Besides, the normative accountability of the research model is strengthened by embracing two social influences, namely subjective norm and image. As the last antecedent to perceived usefulness, prior experience serves to bring in the time variation factor to allow level of prior experience to exert both direct and moderating effects on perceived usefulness.

The resulting research model is analyzed by partial least squares (PLS)-based Structural Equation Modeling (SEM) approach. The research findings reveal that all cultural dimensions demonstrate direct effect on perceived usefulness though the influence of uncertainty avoidance is found marginally significant. Other constructs on innovative characteristics and social influences are validated to be significant as hypothesized. Prior experience does indeed significantly moderate the two influences that perceived usefulness receives from relative advantage and compatibility, respectively. The research model has demonstrated convincing explanatory power and so may be employed for further studies in other contexts. In particular, cultural effects play a key role in contributing to the uniqueness of the model, enabling it to be an effective tool to help critically understand increasingly internationalized IS system development and implementation efforts. This research also suggests several practical implications in view of the findings that could better inform managerial decisions for designing, implementing, or promoting smart card-based E-payment system.

Abstract

Purpose

The purpose of this study is to propose an extended model of technology acceptance model (TAM) in the use of financial technology (Fintech) in the context of Islamic philanthropy, especially by studying and exploring the role of trust, image and religiosity in TAM, and to provide policy recommendation for the authorized organizations in Indonesia regarding several crucial factors that need to be considered so that Indonesian Muslims are willing to use Fintech for philanthropic purposes.

Design/methodology/approach

Online surveys were conducted to collect the data, of which 425 respondents have completed and returned the questionnaire. Multiple linear regression model and multi-variate analysis of variance are applied to test the statistical hypotheses.

Findings

This study supports the theory of reasoned action and the TAM. In which, the relationship between perceived ease of use and perceived usefulness with TAM is determined by trust and religiosity.

Research limitations/implications

It is worth to note the limitation of this study lies in the sampling technique and data collection. Indonesia is a fast archipelago country and consists of 34 provinces, but not all of the provinces are represented in the sample. The selected respondent heavily depends on the previous respondent’s willingness to share the questionnaire. So that the number of respondents does not proportionate to region or province.

Originality/value

This study offers an extended model of TAM that has never been done before, namely, by exploring the role of trust, religiosity and image, in the context of Islamic philanthropy.

Abstract

Purpose

A comprehensive operational framework is proposed to explain young consumers’ (i.e. generations Y and Z) engagement with brands on social media sites (SMSs). This paper aims to synthesize two motivational theories: uses and gratifications (U&G) theory and the technology acceptance model (TAM).

Design/methodology/approach

A selective literature review was conducted to examine recent publications related to young consumers’ brand-driven engagement behavior on SMSs in which either TAM or U&G theory was applied. A three-stage method was used: an initial search was followed by vertical and horizontal searches and then a targeted search of scholarly publications. At each stage, the university’s library databases and Google Scholar were searched for relevant, mainly peer-reviewed articles, using appropriate filters and keywords. The articles’ references and the studies that cited those articles were added to the initially identified research pool (vertical search), coupled with publications of a similar nature based on keywords (horizontal search). The final stage, the targeted search, involved identifying and adding specific articles (e.g. literature reviews and integrated models).

Findings

After a review of a significant number of U&G and TAM studies, similarities and differences of the two theories were identified, and an integrated operational framework was developed. Based on empirical findings of existing U&G and TAM studies, testable propositions were presented.

Research limitations/implications

The proposed hybrid model and the associated propositions provide a research opportunity to empirically examine how young consumers’ motivational (i.e. motivating and demotivating) drivers, normative influence, perceived value and attitudes (toward brand content and engagement) predict intention or actual brand-related behavior on SMSs.

Practical implications

Much of current research indicates that generations Y and Z (“digital natives”) spend considerably more time on SMSs than any of the older generations (“digital immigrants”). Thus, brands that aim to target this cohort need to develop successful engagement strategies (e.g. gamification and influencer marketing) on current and emerging SMSs. The suggested conceptualization provides guidelines for companies to effectively use such communication strategies to motivate young people to engage with their brands on sites such as Twitter, Instagram and Facebook.

Originality/value

A review of TAM research indicates that it lacks rich motivating/demotivating constructs, and thus borrows from other theories to complement this weakness. An examination of U&G frameworks, particularity Ducoffe (1996)-based models, indicates that these frameworks mainly test engagement with social media advertising but seldom other types of brand-driven engagement on SMSs. In addition, many U&G studies focus less than TAM studies do on outcome variables such as behavioral intentions and behavior. Thus, the authors propose a synthesized U&G and TAM framework that mitigates both theories’ weaknesses and builds on their strengths, enriching the growing research on brand-driven engagement behavior via SMSs.

Abstract

Purpose

This study aims to address the following questions: What is enduring about consumer behavior on social media given that digital and social media (DSM) technologies change rapidly? Why do millennials use social media to the extent they do? The authors’ review revealed that a prevailing theoretical approach that may help answer these questions is inadequate. The technology acceptance model (TAM) from information systems was grafted into marketing to explain consumer technology adoption. TAM predicts Facebook adoption effectively, as demonstrated in the authors’ first study, but does not go beyond that in explaining the why’s behind its use. In a second study, the authors used the means-end approach (MEC) complementarily to unearth the why’s of millennials’ use of Facebook.

Design/methodology/approach

The authors used a mixed-methods design combining the structural modeling of TAM with the probing one-on-one interviews and laddering of MEC.

Findings

The authors found that the laddering process both widened and deepened TAM’s scope. It not only confirmed the importance of the TAM attributes, perceived ease of use and perceived usefulness, but it also revealed others, in determining adoption. It was also able to dig deeper from these to uncover a mesh of fundamental values that millennials used Facebook to satisfy, such as belongingness, pleasure, social acceptance and inner harmony, in their quest for inner and relational contentment. The authors also found negative aspects that kept consumers away, such as its lack of privacy and the overwhelming nature of unwanted video in its feed, tying these back to important values.

Research limitations/implications

The authors build on prior exploratory work relating to DSM use and uncover psychological drivers of consumer behavior on social media, by blending TAM in a consumer context, and the MEC approach. The TAM-MEC framework used here offers a technology-independent template for other DSM research, by focusing on how and why consumers use media socially.

Practical implications

Managerially, the authors discuss the building of sustainable marketing strategy on enduring consumer values rather than on transient attributes or technologies. The authors also discuss potential areas of vulnerability for Facebook, such as its increasing use of video and live content, which creates negative consumer sentiment and which may drive consumers to competitors.

Originality/value

By blending the quantitative TAM and the qualitative MEC, something that has not been done before in marketing, this research provides trustworthy answers to the research questions. In so doing, this study also contributes some cohesion to the fragmented DSM research field, as called for recently in prominent journals, by anchoring DSM study in well-established theories in marketing.

Abstract

Purpose

The purpose of this study is to empirically examine the utility of information systems (IS) success models in mandatory e-government services, as opposed to the volitional ones that have been the focus of previous studies. The models include the technology acceptance model (TAM) (1989) and Seddon’s model (1997), which involve three (ease of use, usefulness and citizens satisfaction) and four variables (system quality, information quality, usefulness and citizen satisfaction).

Design/methodology/approach

The models were compared based on a survey conducted on 780 foundation year students of government universities in Saudi Arabia. The Saudi Government has launched a mandatory e-government service geared to assist high school graduates in the university academic admission process. The goodness-of-fit and parsimony of fit indices and the explanatory power were used to compare the two models.

Findings

The structural equation modeling techniques revealed that overall, the two models both exhibited reasonable fit with the collected data, whereas TAM showed the best fit to the sample data and yielded superior goodness-of-fit indices over Seddon’s model. In terms of explanatory power, Seddon’s model predicted 28% (R2 = 0.28) of the variance explained for citizen satisfaction, whereas TAM predicted 21% (R2 = 0.21). All the parsimony of fit indices favored TAM over Seddon’s model.

Research limitations/implications

This study examined the validity of TAM and Seddon’s model, using citizen satisfaction as the dependent variable to compare them. TAM and Seddon’s model were modified to better fit the current research context of mandatory e-government services; thus, the findings may not hold for their original or other voluntary settings. In addition, the focus on a single survey for a certain time in a certain territory of mandatory e-government service may have limited the generalizability of the results to other mandatory contexts. Future research should make use of large, cross-sectional samples in different mandatory contexts to enhance result generalization.

Practical implications

This study’s findings can provide e-government practitioners with deeper perceptions of how to address citizen satisfaction with mandatory e-government services. The results exposed usefulness as the common and major construct, having the strongest influence on citizen satisfaction in both TAM and Seddon’s model; thus, maximizing the benefits of e-government services for citizens is crucial to their success. The causal relationship between information quality and citizen satisfaction was not supported. This supports the perspective that e-government services are currently evolving quickly, becoming more integrated and easier-to-use, generally requiring only a few clicks and less information.

Originality/value

This study has extended the assessment of the validity of IS success models to a mandatory IS usage setting. The comparison study of different IS success models is crucial as it acts as a guide for researchers to determine the trade-off between the models used to conduct research on a particular context. The study concludes that TAM is the most parsimonious and universal model for the study of user satisfaction in mandatory contexts. The findings will provide e-government practitioners with insights into IS success measures suited to enhance the effectiveness of newly and future mandated e-government services.

Abstract

Purpose

Theory is a kind of condensed human knowledge. This paper is to examine the mechanism of interdisciplinary diffusion of theoretical knowledge by tracing the diffusion of a representative theory, the Technology Acceptance Model (TAM).

Design/methodology/approach

Based on the full-scale dataset of Web of Science (WoS), the citations of Davis's original work about TAM were analysed and the interdisciplinary diffusion paths of TAM were delineated, a supervised machine learning method was used to extract theory incidents, and a content analysis was used to categorize the patterns of theory evolution.

Findings

It is found that the diffusion of a theory is intertwined with its evolution. In the process, the role that a participating discipline play is related to its knowledge distance from the original disciplines of TAM. With the distance increases, the capacity to support theory development and innovation weakens, while that to assume analytical tools for practical problems increases. During the diffusion, a theory evolves into new extensions in four theoretical construction patterns, elaboration, proliferation, competition and integration.

Research limitations/implications

The study does not only deepen the understanding of the trajectory of a theory but also enriches the research of knowledge diffusion and innovation.

Originality/value

The study elaborates the relationship between theory diffusion and theory development, reveals the roles of the participating disciplines played in theory diffusion and vice versa, interprets four patterns of theory evolution and uses text mining technique to extract theory incidents, which makes up for the shortcomings of citation analysis and content analysis used in previous studies.

Abstract

Purpose

This paper is the second of two concerned with a meta‐analysis of the technology acceptance model (TAM). This part aims to present a rigorous and quantitative meta‐analytic review of 569 findings from 95 TAM studies as a basis for identifying gaps and providing guidelines for implementation management and conduct of future research. The paper also seeks to investigate the potential impact of methodological characteristics on the meta‐analytic findings.

Design/methodology/approach

The approach consists of meta‐analysis following Hedges and Olkin's procedures, moderator‐analysis using homogeneity Q‐values, analogue to ANOVA and weighted regression method.

Findings

The dominant focus in empirical investigations of the TAM has been on modelling intention for its effect on self‐reported usage behaviour, while the attitudinal construct has been neglected. This raises three questions: whether the exclusion of attitude from the TAM is beneficial for understanding of technology usage behaviour in mandatory settings; whether the revised TAM holds equally for mandatory and voluntary settings; and whether the emphasis on measuring intentions and self‐report use rather than actual usage is warranted. An additional question answered in the meta‐analysis is about the relative importance of PU and PEOU.

Originality/value

The paper provides a rigorous meta‐analysis to progress towards a unified view of the TAM.

Abstract

Purpose – The purpose of this paper is to provide a case study for professionals who are in research and practice in maintenance engineering. Design/methodology/approach – This is a case study. Therefore, on‐site involvement in the development of steps for maintenance projects has been included. Findings – The case study shows that, if project management practice and involvement of external experts and parties are allowed in the maintenance projects, then issues in maintenance projects can be addressed more clearly and the cost and schedule for such a maintenance project can also be optimized. The use of information technology in the whole process can be facilitated not only during the planning phase, but also during the execution and review process. Research limitations/implications – Implication of this study can be seen in TAM projects where time and energy have to be spent to get the best practice. The case study will show a real life example of TAM. Practical implications – The paper should help one to understand the implications of starting a turn‐around maintenance project and the issues built therein. The case study highlights that collaborative planning and execution of TAM are useful. Collaboration could be in terms of internal parties, such as decision makers and managers, or of external parties, such as external experts and contractors. Originality/value – There are only a few studies in the turn‐around management process. As oil refining is an important economic process, learning of cases in one of the major oil‐refining plants can help others to emulate the process so that overall efficiency of turn‐around maintenance can be increased across the industry.
