Abstract
Purpose
The purpose of this study is to evaluate the effect of motivation on job satisfaction and organizational performance in the context of container shipping companies in Taiwan. Four motivation dimensions were identified based on an exploratory factor analysis, including remuneration, job achievement, job security and job environment. In addition, five job satisfaction dimensions were identified, namely: job policy, job autonomy, job workload, job performance and job status. Organizational performance dimensions included financial and non-financial performance.
Design/methodology/approach
Factor analysis was used to summarize a large number of motivation, job satisfaction and organizational performance attributes to identify the crucial factors. Reliability tests based on Cronbach’s alpha and corrected item-total correlation coefficients was used to test the internal consistency of questionnaire responses. ANOVA tests were subsequently used to test for differences in respondents’ perception of these factors according to selected demographics. Finally, a multiple regression model analysis was conducted to examine the relationships between motivation, job satisfaction and organizational performance.
Findings
Results indicated that remuneration and job performance had a positive effect on financial performance dimensions such as return on assets, turnover growth rate and profitability while job environment and job autonomy had a positive effect on non-financial performance dimensions, such as customer service, employee productivity and service quality.
Originality/value
This study has drawn attention to the importance of the relationships between motivation, job satisfaction and organizational performance in the container shipping context. The findings have significant implications for researchers and shipping practitioners. Despite the existence of research on the inter-relationships between motivation, job satisfaction and organizational performance in other disciplines, no empirical study was discussed in previous shipping or transportation-related research.

Abstract
Purpose
The purpose of this study is to identify the critical success factors to international ship finance centre (ISFC) and to understand the reasons behind ship financing decision by shipowners and their views on the potential of Shanghai to become an ISFC in the near future.
Design/methodology/approach
Survey questionnaire and follow-up interviews were conducted. The survey of this study was conducted by firstly sending online questionnaire with interview questions via email and then carrying out interview either on telephone or in-person with the interview questions to collect factual data and views from individual interviewees.
Findings
This study identified governmental support and stable policy, sound and favourable legal system, advanced maritime cluster and dynamic source of finance as critical success factors which can help Shanghai to evolve into an international maritime centre with dual function as an ISFC which is a synthesis with the maritime sector of an international finance centre.
Originality/value
This paper is known to be the first to link international maritime centre with ISFC.

To review conceptual links between research on personal epistemological beliefs and leadership behaviours associated with the transformational‐transactional leadership model.
Abstract
Purpose
To review conceptual links between research on personal epistemological beliefs and leadership behaviours associated with the transformational‐transactional leadership model.
Design/methodology/approach
Transformational leaders act as facilitators of learning in organisations, and therefore their beliefs, cognitions and behaviours can be explored in the same manner as teachers in classroom settings. Research on both personal epistemological beliefs and the transformational‐transactional leadership model is reviewed and key conceptual links are identified in the areas of underlying beliefs, metacognition and cognition, and implications for training.
Findings
The literature review suggests that strong conceptual links exist between mature personal epistemology and beliefs and behaviours associated with transformational leadership. Similarly, conceptual links exist between less mature personal epistemology and beliefs and behaviours associated with transactional leadership.
Research limitations/implications
This is a conceptual paper that will require further empirical investigation. However, studies of the personal epistemology of leaders may provide insights into their behaviours and beliefs associated with transformational and transactional leadership.
Practical implications
Research indicates that personal epistemology can be affected through appropriate interventions. Thus, training programmes designed to facilitate adoption of transformation leadership behaviours could be informed by such research.
Originality/value
This paper is original in its conceptualisations of beliefs potentially underpinning transformational leadership. It offers a new line of inquiry for further research into transformational leadership behaviours and ways that such behaviours can be influenced through metacognitive and cognitive interventions.

Abstract
Purpose
Cantilever plates subject to axial flow can lose stability by flutter and properties such as viscoelasticity and laminar friction affect dynamic stability. The purpose of the present study is to investigate the dynamic stability of viscoelastic cantilever plates subject to axial flow by using the differential quadrature method.
Design/methodology/approach
Equation of motion of the viscoelastic plate is derived by implementing Kelvin-Voigt model of viscoelasticity and applying inverse Laplace transformation. The differential quadrature method is employed to discretize the equation of motion and the boundary conditions leading to a generalized eigenvalue problem. The solution is verified using the existing results in the literature and numerical results are given for critical flow velocities
Findings
It is observed that higher aspect ratios lead to imaginary part of third frequency becoming negative and causing single-mode flutter instability. It was found that flutter instability does not occur at low aspect ratios. Moreover the friction coefficient is found to affect the magnitude of critical flow velocity, however, its effect on the stability behaviour is minor.
Originality/value
The effects of various problem parameters on the dynamic stability of a viscoelastic plate subject to axial flow were established. It was shown that laminar friction coefficient of the flowing fluid increases the critical fluid velocity and higher aspect ratios lead to single-mode flutter instability. The effect of increasing damping of viscoelastic material on the flutter instability was quantified and it was found that increasing viscoelasticity can lead to divergence instability.

– The purpose of this paper is to propose a social semiotic approach to analysing objects of learning in terms of their critical aspects.
Abstract
Purpose
The purpose of this paper is to propose a social semiotic approach to analysing objects of learning in terms of their critical aspects.
Design/methodology/approach
The design for this paper focuses on how the semiotic resources – including language, equations, and diagrams – that are commonly used in physics teaching realise the critical aspects of a common physics object of learning. A social semiotic approach to the analysis of a canonical text extract from optics is presented to illustrate how critical aspects can be identified.
Findings
Implications for university teaching and learning of physics stemming from this social semiotic approach are suggested.
Originality/value
Hitherto under-explored similarities between the Variation Theory of Learning, which underpins learning studies, and a social semiotic approach to meaning-making are identified. These similarities are used to propose a new, potentially very powerful approach to identifying critical aspects of objects of learning.

Abstract
Purpose
The purpose of this study is to design a wearable medical device as a human care platform and to introduce the design details, key technologies and practical implementation methods of the system.
Design/methodology/approach
A multi-channel data acquisition scheme based on PCI-E (rapid interconnection of peripheral components) was proposed. The flexible biosensor is integrated with the flexible data acquisition card with monitoring capability, and the embedded (device that can operate independently) chip STM32F103VET6 is used to realize the simultaneous processing of multi-channel human health parameters. The human health parameters were transferred to the upper computer LabVIEW by intelligent clothing through USB or wireless Bluetooth to complete the transmission and processing of clinical data, which facilitates the analysis of medical data.
Findings
The smart clothing provides a mobile medical cloud platform for wearable medical through cloud computing, which can continuously monitor the body's wrist movement, body temperature and perspiration for 24 h. The result shows that each channel is completely accurate to the top computer display, which can meet the expected requirements, and the wearable instant care system can be applied to healthcare.
Originality/value
The smart clothing in this study is based on the monitoring and diagnosis of textiles, and the electronic communication devices can cooperate and interact to form a wearable textile system that provides medical monitoring and prevention services to individuals in the fastest and most accurate way. Each channel of the system is precisely matched to the display screen of the host computer and meets the expected requirements. As a real-time human health protection platform technology, continuous monitoring of human vital signs can complete the application of human motion detection, medical health monitoring and human–computer interaction. Ultimately, such an intelligent garment will become an integral part of our everyday clothing.

Abstract
Purpose
The purpose of this paper is to study the mechanical property of three-dimensional (3D) Printed photopolymer (Vero Yellow and Tango Black) with different constant strain rate. According to the experimental results, three constitutive models are used to describe the stress-strain and stress-time relation in the tension and stress relaxation process.
Design/methodology/approach
The Stratasys Objet 260 was used to prepare the four groups of samples with different photopolymers (Vero Yellow and Tango Black). The stress-strain and stress-time relations are obtained by the uniaxial tensile tests and relaxation tests performed at room temperature with different constant strain rates. The generalized Kelvin model (GKM), standard linearized model (SLM) and fractional order model (FOM) are used to describe experimental data by means of the curve-fitting approach.
Findings
Experimental results show that the tension stress increases faster at a higher strain-rate for tensile tests. Relaxation stress is influenced by the preload strain-rate for relaxation tests. For the theoretical fitting, the error comparison between three constitutive models and experimental data are calculated to demonstrate the high accuracy in describing the stress-strain relationship for tension. For stress relaxation, the error comparison confirms higher accuracy of FOM with the largest error within 3%, while the error of GKM and SLM up to 10%.
Originality/value
The paper confirms the viscous-elastic mechanical property of 3D printed photopolymer composites (Vero Yellow and Tango Black) for Stratasys PolyJet. As FOM shows high accuracy both in describing stress-strain and stress-time relation for tension and stress relaxation process, it can be directly used as a constitutive model to predict mechanical properties for engineering application.

Abstract
Purpose
The purpose of this paper is to provide a summarization and review of the present author's main investigations on failure modes of reticular metal foams under different loadings in engineering applications.
Design/methodology/approach
With the octahedral structure model proposed by the present authors themselves, the fundamentally mechanical relations have been systematically studied for reticular metal foams with open cells in their previous works. On this basis, such model theory is continually used to investigate the failure mode of this kind of porous materials under compression, bending, torsion and shearing, which are common loading forms in engineering applications.
Findings
The pore-strut of metal foams under different compressive loadings will fail in the tensile breaking mode when it is brittle. While it is ductile, it will tend to the shearing failure mode when the shearing strength is half or nearly half of the tensile strength for the corresponding dense material and to the tensile breaking mode when the shearing strength is higher than half of the tensile strength to a certain value. The failure modes of such porous materials under bending, torsional and shearing loads are also similarly related to their material species.
Originality/value
This paper presents a distinctive method to conveniently analyze and estimate the failure mode of metal foams under different loadings in engineering applications.
