Abstract
Purpose
At airport security checkpoints, baggage screening is aimed to prevent transportation of prohibited and potentially dangerous items. Observing the projection images generated by X-rays scanner is a critical method. However, when multiple objects are stacked on top of each other, distinguishing objects only by a two-dimensional picture is difficult, which prompts the demand for more precise imaging technology to be investigated for use. Reconstructing from 2D X-ray images to 3D-computed tomography (CT) volumes is a reliable solution.
Design/methodology/approach
To more accurately distinguish the specific contour shape of items when stacked, multi-information fusion network (MFCT-GAN) based on generative adversarial network (GAN) and U-like network (U-NET) is proposed to reconstruct from two biplanar orthogonal X-ray projections into 3D CT volumes. The authors use three modules to enhance the reconstruction qualitative and quantitative effects, compared with the original network. The skip connection modification (SCM) and multi-channels residual dense block (MRDB) enable the network to extract more feature information and learn deeper with high efficiency; the introduction of subjective loss enables the network to focus on the structural similarity (SSIM) of images during training.
Findings
On account of the fusion of multiple information, MFCT-GAN can significantly improve the value of quantitative indexes and distinguish contour explicitly between different targets. In particular, SCM enables features more reasonable and accurate when expanded into three dimensions. The appliance of MRDB can alleviate problem of slow optimization during the late training period, as well as reduce the computational cost. The introduction of subjective loss guides network to retain more high-frequency information, which makes the rendered CT volumes clearer in details.
Originality/value
The authors' proposed MFCT-GAN is able to restore the 3D shapes of different objects greatly based on biplanar projections. This is helpful in security check places, where X-ray images of stacked objects need to be distinguished from the presence of prohibited objects. The authors adopt three new modules, SCM, MRDB and subjective loss, as well as analyze the role the modules play in 3D reconstruction. Results show a significant improvement on the reconstruction both in objective and subjective effects.

Abstract
There is strong consensus that the Internet has the potential to positively impact firms, and SMEs in particular; however, not all firms have realized benefits from adoption. The present study extends research in the area by addressing the need to examine the “chain” of variables explaining Internet adoption. We do this by exploring SME owner/manager Internet-related usefulness and ease-of-use cognitions and intention to use the Internet for supplier information management. We also explore the influence of behavioral norms and two broader strategic perspectives, market and learning orientation, on the Internet-related cognitions. Findings have implications for researchers and practitioners by identifying factors that contribute to effectively leveraging the Internet in an important area for SMEs.

Abstract
Purpose
Consumer ethnocentrism (CE) is a matter of interest for marketers over the decades. However, buying intentions toward domestically produced household electronic products in developing and underdeveloped countries have not been examined sufficiently. Hence, this study investigated the consumers' ethnocentrism and attitude toward domestically-produced household electronic goods. The purpose of this study is to examine the influence of consumer demographic attributes on ethnocentrism and its moderating effect on choosing domestically produced household electronic goods in the context of Bangladesh.
Design/methodology/approach
Primary data have been collected from a sample of 172 respondents using a mall-intercept survey. Consumers' ethnocentrism level has been measured using CETSCALE on a five-point Likert scale. ANOVA and t-test were performed to compare different demographic groups regarding ethnocentrism levels. This study also applied the qualitative method by applying a manual approach.
Findings
The result shows that consumers' ethnocentrism levels do not vary with gender and income level. However, other demographic attributes, like occupation, age and education level, play a considerable role in CE tendency.
Originality/value
The study is one of the few that examines the consumers' ethnocentrism and attitudes toward electronic products produced in a developing country. The researchers expect that the outcome of the study would contribute to the domestic manufacturer focusing more rigorously on producing electronic products that would be accepted locally as well as globally.

Abstract
Purpose
Concepts of health and wellbeing have long been conceived as relevant to leisure, recreation and rejuvenation. These are now conceived as being necessary and useful as potential measures of success in community development and in that subset of leisure and recreation pursuits that is designated as tourism at a destination. The paper aims to discuss this issue.
Design/methodology/approach
A post-modern approach to development of community and markers of sustainable development more-or-less correspond to sustainable development goals (there are 17) that often overlay the concepts of good health and wellbeing that concern all stakeholders.
Findings
This paper encompasses best practice experiences from two case studies conducted in a tourism “hot spot” in the environs of the first National Park established in Derbyshire in the UK. There is some urgency about this topic as resources for community development are increasingly under pressure from local, central government and the expectation is now that local communities take full responsibility for that development. An inter-disciplinary approach using concepts of health and wellbeing is recommended.
Originality/value
Wellbeing may demand a greater allocation of scarce resources in an era of self-determination, bottom-up and locally sourced community aspiring to become, or remain, a destination of choice. Two case studies’ outcomes in this development are presented with a special focus on creation of a repository for the know-how and know what of the learning acquired.

Abstract
Purpose
Drawing upon the resource-based view and the contingency theory, the purpose of this paper is to build and test a framework of: the interaction between market orientation (MO) and accountants’ participation in strategic decision making; and its subsequent effect on the use of management accounting systems (MASs), which, in turn, enhances firm performance.
Design/methodology/approach
The hypotheses were empirically tested using partial least square-structural equation modeling with survey data from 171 large business firms in Vietnam. The standardized root mean squared residual value of the composite model was also examined using SmartPLS3 to test the model fit. The marker-variable technique was employed to test common method bias.
Findings
This study has two key findings: first, the use of MAS (in terms of broad scope, timeliness, aggregation, and integration) mediates the effect of MO on firm performance. Second, the degree of accountants’ participation in strategic decision making elevates the positive relationship between MO and the use of MAS.
Originality/value
This study is one of the first empirical attempts to test the contingent roles of accountants’ participation in strategic decision making and the use of MAS information in driving performance of market-oriented firms in the context of a transition market.
