The purpose of this study is to present the theoretical framework of the “data envelopment analysis (DEA) Energy Management System (DEMS)” proposed to assist individual departments occupying the same buildings on university campus in assessing the energy efficiencies of their facilities, as well as to demonstrate the implementation results of the DEMS applied in the case of the Department of Architecture of NTUST in Taiwan.

The proposed DEMS considers each “space” within a department in a given “time” (such as a month) as a decision-making unit (DMU). Then, regression analysis is performed on data of “existing environment”, “occupancy” factors and “actual energy consumption EUI (energy usage intensity)” related variables. The regression equation derived is then used to calculate the “predicted EUI” for all DMUs. The “actual EUI” is further considered as the input data and the “predicted EUI” as the output data of the DEMS, on which data envelopment analysis is conducted to produce three types of energy-efficiency scores (overall efficiency, scale efficiency, pure technical efficiency) to indicate the energy efficiencies of all DMUs.

The DEMS was developed and further implemented in the Department of Architecture of NTUST in Taiwan to illustrate how it can be used to assist individual departments within universities in assessing the energy management effectiveness of their spaces.

The accuracy of the energy-efficiency scores depends greatly on the accuracy of the predicted EUIs of spaces, and, therefore, it is critical to identify a better regression model with higher predictability (R2). The relatively low actual EUIs of certain student spaces during winter and summer breaks may greatly affect the resulting energy-efficiency scores.

The DEMS allows facility managers to assess and compare the energy-efficiency scores “among different spaces”, to further review the energy efficiency of a space “over time” and to recognize the benchmark cases and pursue actions for energy improvement.

This study explores the research concepts of “space type” and “internal benchmark” with an analytical method “data envelopment analysis” to assess the energy efficiency of an individual department which may only occupy certain floors of a building.

The purpose of this paper is to present and discuss a conceptual model of purchase intentions, trust, and e‐servicescape that presents online physical environments as comprising three dimensions. It aims to develop and extend existing research into physical service environments through proposing, operationalizing, and testing a model of online servicescape.

The study utilizes a survey approach to gather data regarding consumers' perceptions of online servicescape. Surveys were administered to 257 respondents regarding a broad range of web sites.

A measure of e‐servicescape is evaluated that comprises three dimensions and 52 items while relationships between the dimensions of e‐servicescape, trust, and purchase intentions are described.

The first contribution of this study stems from the successful operationalization of a comprehensive multi‐item (in total 52 items), multi‐scale (nine scales), multi‐dimensional (three) measure of e‐servicescape. Second, a contribution is made through the finding that trust constitutes a key variable during online exchange. Third, we contribute insights into the antecedents of consumers' purchase intentions. Finally, the study reveals that consumers' interpretations of online environments exert a powerful influence over trust and purchase intentions.

The findings of this study also have numerous implications for both services managers and internet developers. The findings supply valuable insights into which factors practitioners should focus their attention to better tailor their approaches. This study strongly endorses the view that the loyalty intentions of online customers are linked to the extent to which they trust the service provider.

Assessing front end engineering design (FEED) accuracy is significant for project owners because it can support informed decision-making, including confidence in cost and schedule predictions. A framework to measure FEED accuracy does not exist in the literature or in practice, not does systematic data directly linking FEED accuracy to project performance. This paper aims to focus first on gauging and quantifying FEED accuracy, and second on measuring its impact on project performance in terms of cost change, schedule change, change performance, financial performance and customer satisfaction.

A novel measurement scheme was developed for FEED accuracy as a comprehensive assessment of factors related to the project leadership and execution teams, management processes and resources; to assess the environment surrounding FEED. The development of this framework built on a literature review and focus groups, and used the research charrettes methodology, guided by a research team of 20 industry professionals and input from 48 practitioners representing 31 organizations. Data were collected from 33 large industrial projects representing over $8.8 billion of installed cost, allowing for a statistical analysis of the framework's impact on performance.

This paper describes: (1) twenty-seven critical FEED accuracy factors; (2) an objective and scalable method to measure FEED accuracy; and (3) data showing that projects with high FEED accuracy outperformed projects with low FEED accuracy by 20 percent in terms of cost growth in relation to their approved budgets.

FEED accuracy is defined as the degree of confidence in the measured level of maturity of the FEED deliverables to serve as a basis of decision at the end of detailed scope, prior to detailed design. Assessing FEED accuracy is significant for project owners because it can support informed decision-making, including confidence in cost and schedule predictions.

FEED accuracy has not been assessed before, and it turned out to have considerable project performance implications. The new framework presented in this paper is the first of its kind, it has been tested rigorously, and it contributes to both the literature body of knowledge as well as to practice. As one industry leader recently stated, “it not only helped to assess the quality and adequacy of the technical documentation required, but also provided an opportunity to check the organization's readiness before making a capital investment decision.”

The purpose of this paper is to deal with the practical challenge faced by modern logistics enterprises to accurately evaluate driving performance with high computational efficiency under the disturbance of road smoothness and to identify significantly associated performance influence factors.

The authors cooperate with a logistics server (G7) and establish a driving grading system by constructing real-time inertial navigation data-enabled indicators for both driving behaviour (times of aggressive speed change and times of lane change) and road smoothness (average speed and average vibration times of the vehicle body).

The developed driving grading system demonstrates highly accurate evaluations in practical use. Data analytics on the constructed indicators prove the significances of both driving behaviour heterogeneity and the road smoothness effect on objective driving grading. The methodologies are validated with real-life tests on different types of vehicles, and are confirmed to be quite effective in practical tests with 95% accuracy according to prior benchmarks. Data analytics based on the grading system validate the hypotheses of the driving fatigue effect, daily traffic periods impact and transition effect. In addition, the authors empirically distinguish the impact strength of external factors (driving time, rainfall and humidity, wind speed, and air quality) on driving performance.

This study has good potential for providing objective driving grading as required by the modern logistics industry to improve transparent management efficiency with real-time vehicle data.

This study contributes to the existing research by comprehensively measuring both road smoothness and driving performance in the driving grading system in the modern logistics industry.

This study aims to examine the effects of cyberbullying on the academic lives of Ghanaian university students. It also establishes whether cyberbullying victims, perpetrators, victim-perpetrators and bystanders differed in their thoughts on the effects of cyberbullying on students’ academic lives.

This study is anchored on Bandura’s theory of triadic reciprocal determinism and Abraham Maslow’s theory of needs. This study uses a cross-sectional survey design and quantitative approach to collect the data from 1,374 students from three public universities. The authors use descriptive statistics and ANOVA techniques to analyse the data.

The results show that the effects of cyberbullying on academic life are difficulty concentrating on studies, difficulty studying in groups and difficulty assessing important academic information online. There is also a statistically significant difference among cyberbullying victims, perpetrators, victim-perpetrators and bystanders in their thoughts on the effects of cyberbullying on students’ academic lives.

This research contributes to the literature on cyberbullying in the Ghanaian tertiary education environment. Even though the impact of cyberbullying on academics in Ghanaian universities may seem minimal, it is still imperative that it be checked, as it is significant enough to disrupt effective academic work. Thus, this study adds to the existing literature on cyberbullying from a developing country perspective.

The use of digital technology in firms has drawn attention of innovation management scholars and policy-makers, especially the imitation of digital technology and competition among peer firms. Drawing on dynamic competition theory, this paper examines how firms react to their peers' digital innovation behavior and the effect of external environment mechanisms on the magnitude of peer effects.

This paper utilizes a text mining method to construct a baseline model with a Tobit estimator using data obtained for Chinese listed firms.

The findings suggest that peer effects on digital innovation behavior are robust and significant positive in China. Moreover, peer effects on digital innovation participation are positively magnified by firms' strong social network and high Fintech development. However, peer effects are relatively higher in non-state-owned enterprises (non-SOEs), low-profitability and high R&D firms.

The authors' findings contribute to the digital management literature by showing that firms need digital technological imitation and diffusion of innovations in the digital era.

Managers should provide insights into firms' imitation of their peers' acts to preserve competitive parity. Besides, firms should integrate employees within the organization and communicate digital innovation concepts and behaviors to external peer firms.

First, this paper contributes to explaining how firms change their digital innovation strategy through the influence of peers' digital innovation behavior. Second, this paper fills the literature gaps related to the moderating effects of external environment factors in peer effects of digital innovation behavior.

The purpose of this paper is to examine the potential influence of the mobile banking (M banking) servicescape on customer attitude and engagement. The stimulus-organism-response framework was adapted to formulate a conceptual model, in which the M banking servicescape was modelled as an antecedent (stimulus) of customer attitudes towards M banking (organism), in turn directing customer behaviour (response), namely, customer engagement.

A web-based survey of 345 M banking users was conducted to gather data. The structural equation modelling technique was employed to analyse the conceptual model and test the proposed set of hypotheses.

The results of data analyses showed that M banking servicescape is a strong predictor of customer attitude towards M banking, which then influences customer engagement. The findings also demonstrate that customer attitudes towards M banking mediate both the M banking servicescape and engagement.

The extension of servicescape literature from the physical to the online context of M banking provides a notable new realm in which academicians can extend the current paradigms. This study also enhances understanding of potential improvements to customer attitude towards and engagement with M banking.

The purpose of the study is to develop and empirically test a model which examines the relationship between e-servicescape dimensions, website quality dimensions, website stickiness, website loyalty and word-of-mouth (WOM). The role of WOM in influencing consumer behaviour is documented in literature. However, despite its growing importance, research on the antecedents of WOM in the e-retail context is sparse.

Data were collected by circulating the questionnaire using an online survey from the graduate and undergraduate students enrolled in a large university in the northeastern USA. Out of 660 questionnaires distributed, 509 were usable. Data were analysed using confirmatory factor analysis and structural equation modelling.

Results show that website stickiness and website loyalty are two different constructs which form the immediate antecedents of WOM. Results also show the indirect effects of e-servicescape and website quality dimensions on WOM.

The findings of the study provides a better understanding of the factors likely to influence the WOM behaviour of e-retail store customers. Findings also provide valuable insights into the factors which managers need to focus on to make their e-retail website increasingly stickier.

The contribution of the paper lies in eliciting the differences between stickiness to and loyalty to retail websites and extending the research on e-servicescapes.

Information and communications technology (ICT) offers enormous opportunities for individuals, businesses and society. The application of ICT is equally important to economic and non-economic activities. Researchers have increasingly focused on the adoption and use of ICT by small and medium enterprises (SMEs) as the economic development of a country is largely dependent on them. Following the success of ICT utilisation in SMEs in developed countries, many developing countries are looking to utilise the potential of the technology to develop SMEs. Past studies have shown that the contribution of ICT to the performance of SMEs is not clear and certain. Thus, it is crucial to determine the effectiveness of ICT in generating firm performance since this has implications for SMEs’ expenditure on the technology. This research examines the diffusion of ICT among SMEs with respect to the typical stages from innovation adoption to post-adoption, by analysing the actual usage of ICT and value creation. The mediating effects of integration and utilisation on SME performance are also studied. Grounded in the innovation diffusion literature, institutional theory and resource-based theory, this study has developed a comprehensive integrated research model focused on the research objectives. Following a positivist research paradigm, this study employs a mixed-method research approach. A preliminary conceptual framework is developed through an extensive literature review and is refined by results from an in-depth field study. During the field study, a total of 11 SME owners or decision-makers were interviewed. The recorded interviews were transcribed and analysed using NVivo 10 to refine the model to develop the research hypotheses. The final research model is composed of 30 first-order and five higher-order constructs which involve both reflective and formative measures. Partial least squares-based structural equation modelling (PLS-SEM) is employed to test the theoretical model with a cross-sectional data set of 282 SMEs in Bangladesh. Survey data were collected using a structured questionnaire issued to SMEs selected by applying a stratified random sampling technique. The structural equation modelling utilises a two-step procedure of data analysis. Prior to estimating the structural model, the measurement model is examined for construct validity of the study variables (i.e. convergent and discriminant validity).

The estimates show cognitive evaluation as an important antecedent for expectation which is shaped primarily by the entrepreneurs’ beliefs (perception) and also influenced by the owners’ innovativeness and culture. Culture further influences expectation. The study finds that facilitating condition, environmental pressure and country readiness are important antecedents of expectation and ICT use. The results also reveal that integration and the degree of ICT utilisation significantly affect SMEs’ performance. Surprisingly, the findings do not reveal any significant impact of ICT usage on performance which apparently suggests the possibility of the ICT productivity paradox. However, the analysis finally proves the non-existence of the paradox by demonstrating the mediating role of ICT integration and degree of utilisation explain the influence of information technology (IT) usage on firm performance which is consistent with the resource-based theory. The results suggest that the use of ICT can enhance SMEs’ performance if the technology is integrated and properly utilised. SME owners or managers, interested stakeholders and policy makers may follow the study’s outcomes and focus on ICT integration and degree of utilisation with a view to attaining superior organisational performance.

This study urges concerned business enterprises and government to look at the environmental and cultural factors with a view to achieving ICT usage success in terms of enhanced firm performance. In particular, improving organisational practices and procedures by eliminating the traditional power distance inside organisations and implementing necessary rules and regulations are important actions for managing environmental and cultural uncertainties. The application of a Bengali user interface may help to ensure the productivity of ICT use by SMEs in Bangladesh. Establishing a favourable national technology infrastructure and legal environment may contribute positively to improving the overall situation. This study also suggests some changes and modifications in the country’s existing policies and strategies. The government and policy makers should undertake mass promotional programs to disseminate information about the various uses of computers and their contribution in developing better organisational performance. Organising specialised training programs for SME capacity building may succeed in attaining the motivation for SMEs to use ICT. Ensuring easy access to the technology by providing loans, grants and subsidies is important. Various stakeholders, partners and related organisations should come forward to support government policies and priorities in order to ensure the productive use of ICT among SMEs which finally will help to foster Bangladesh’s economic development.
