Future waterborne transport operations in short-sea, sea-river, and inland waterways can be performed by autonomous vessels. The automation of maritime shipping directly emphasizes reducing crew numbers, minimizing operational costs, andmitigating human error during the operation. Recent researches have focused on understanding autonomous navigation while the reliability of unattended machinery plant has received very little attention. This paper aims at developing a method for predicting the performance of failure-sensitive components that may be left unattended in autonomous shipping. The presented methodology adopts Bayesian Inference as the basis of the artificial intelligence for predicting maintenance schedules including repair, inspection, and irregular checks of unattended systems. A Multinomial Process Tree (MPT) is used to model the failures within the system, identify faulty components, and to predict their failure times. A real case study from a short sea voyage is adopted to demonstrate the application of the presented methodology. The results of this research will assist decision and policy-makers to prevent costly failures in Maritime Autonomous Surface Ships (MASS) and extend the service life of autonomous systems before any human intervention.

Women’s empowerment has been at the centre of research focus for many decades. Extant literature examined the process, outcome and various challenges. Some claimed substantial success, while others contradicted with evidence of failure. But the success remains a matter of debate due to lack of empirical evidence of actual empowerment of women around the world. The current study aimed to address this gap by taking a case study method. The study critically evaluates 20 cases carefully sampled to include representatives from the entire country of Bangladesh. The study demonstrates popular beliefs about microfinance often misguide even the borrowers and they start living in a fabricated feeling of empowerment, facing real challenges to achieve true empowerment in their lives. The impact of this finding is twofold; firstly there is a theoretical contribution, where the definition of women’s empowerment is proposed to be revisited considering findings from these cases. And lastly, the policy makers at governmental and non-governmental organisations, and multinational donor agencies need to revise their assessment tools for funding.

Financial inclusion and startup are two topics, which recently get attention of academic researchers and policy makers in Vietnam. One of the important factors for setting up a successful startup is the financial capability of the owners. Therefore, financial inclusion has a strong correlation with startup establishment. This article tested the effects of several factors in financial index (findex) developed by World Bank on startup establishment in some OECD countries. The result showed that borrowing from friends and relatives along with from credit institutions and opening a debit account at banks have  significant impacts on startup establishment in these countries. Finally, the article presented several recommendations for policy makers to stimulate the startup growth in Vietnam in the next time.

The objective of this study was to measure the level of cruise tourists' satisfaction as well as the relationship between satisfaction, recommendation, return intention, and expenditure. Also, the impact of factors such as nationality, length of the visit, and age on the level of expenditure was measured. An empirical approach for data collection was followed and a total of 152 questionnaires were collected from cruise tourists visiting the capital city of Oman, Muscat, as cruise liners anchor at Sultan Qaboos Port. Results of the regression analysis supported the existence of a causal relationship between satisfaction with destination attributes, overall satisfaction, recommendation, return intention, and expenditure. It was found that the average expenditure varies according to age and length of the visit. Recommendations for policy makers were suggested on how to increase the role of cruise tourism in strengthening the economy.

This paper aims to propose a comprehensive framework for a clear description of system boundary conditions in life cycle energy assessment (LCEA) analysis in order to promote the incorporation of embodied energy impacts into building energy-efficiency regulations (BEERs). The proposed framework was developed based on an extensive review of 66 studies representing 243 case studies in over 15 countries. The framework consists of six distinctive dimensions, i.e., temporal, physical, methodological, hypothetical, spatial, and functional. These dimensions encapsulate 15 components collectively. The proposed framework possesses two key characteristics; first, its application facilitates defining the conditions of a system boundary within a transparent context. This consequently leads to increasing reliability of obtained LCEA results for decision-making purposes since any particular conditions (e.g., truncation or assumption) considered in establishing the boundaries of a system under study can be revealed. Second, the use of a framework can also provide a meaningful basis for cross comparing cases within a global context. This characteristic can further result in identifying best practices for the design of buildings with low life cycle energy use performance. Furthermore, this paper applies the proposed framework to analyse the LCEA performance of a case study in Adelaide, Australia. Thereafter, the framework is utilised to cross compare the achieved LCEA results with a case study retrieved from literature in order to demonstrate the framework’s capacity for cross comparison. The results indicate the capability of the framework for maintaining transparency in establishing a system boundary in an LCEA analysis, as well as a standardised basis for cross comparing cases. This study also offers recommendations for policy makers in the building sector to incorporate embodied energy into BEERs.

This paper sets out to enhance current Maritime Crew Resource Management (MCRM) training, and with that to improve the training of technical and non-technical skills given to bachelor maritime officers. The rationale for CRM training is improving safety performance by reducing accidents caused by human error. The central notion of CRM training is that applying good resource management principles during day-to-day operations will lead to a beneficial change in attitudes and behaviour regarding safety. This article therefore indicates that enhanced MCRM should play a more structural role in the training of student officers. However, the key question is: what are the required changes in attitude and behaviour that will create sufficient adaptability to improve safety performance? To provide an answer, we introduce the Resilience Engineering (RE) theory. From an RE point of view, we elaborate on the relation between team adaptability and safety performance, operationalized as a competence profile. In addition, a case study of the ‘Rotterdam Approach’ will be presented, in which the MCRM training design has been enhanced with RE, with the objective to train team adaptability skills for improved safety performance.

During the last few decades, research and development (R&D) have always been regarded as the most important or even the only factor in the attempt to explain the innovation capability and performance of enterprises, industries and economies, while to a large extent, those heterogeneous innovation activities beyond formal R&D are ignored or underestimated. Some research has shown that non-R&D innovation activities contribute to make full use of resources beyond R&D to promote performance, especially to small- and medium-sized enterprises (SMEs) with weak R&D capability. However, non-R&D innovators’ behavior is still a black box by far, and especially few empirical research have been conducted in China context. This paper first explores the heterogeneous innovation patterns of non-R&D innovation by survey among Chinese SMEs in Zhejiang Province. It shows that, product and service customization, imitation and design, technology adoption and incremental modification, organizational innovation and marketing innovation are the main patterns of non-R&D innovation in China. Then, a case study is followed to cross-validate the patterns and relationships between non-R&D innovation and growth of SMEs in China. Generally, this study has implications for both academia and policy-makers. As it demonstrates, non-R&D innovation is an effective way for SMEs to quickly grow and sustain competitiveness in competition. On the other hand, this study helps to optimize some of current innovation policies for SMEs in China, where policy incentives are mainly R&D-focused. It also likely sheds light on the SMEs in other emerging economies.

The total area of solar collectors installed in Taiwan had exceeded 2 million square meters by the end of 2010. However, there were only 98 systems in operation with area of solar collectors installed exceeding 100 square meters from 2001 to 2010. To increase industrial awareness of solar water heating technologies, a nursery greenhouse was chosen as the case study to evaluate its thermal performance throughout the months of May 2010 to April 2011. The results showed that the solar energy collected and heat loss during the night hours would affect the thermal efficiency, economic viability and attractiveness of a SWH. This study would provide useful information for all parties related to this market, manufacturers, potential users and policy-makers.

Purpose – The purpose of this paper is twofold. First, to explore to what extent being located in a territory is value-relevant for a company. Second, to understand if a company is aware of, and how it can sustain, the territorial tangible and intangible assets present in the economic area in which it is located. Design/methodology/approach – The study presents an empirical multiple case-study, investigating ten mid-/large-sized Italian companies in manufacturing sectors. Findings – The results indicate that the sampled manufacturing companies are intertwined with the environment in which they are embedded, both in their home country and in host ones. The domestic territorial capital has provided, and still provides, enterprises with workers endowed with the necessary technical skills that they can have great difficulty in finding in other places. In turn, companies support territorial capital generation through their activities. Research limitations/implications – To increase the generalisability of the results, future research should expand the sample and examine firms based in different countries and sectors. Practical implications – Implications for policy makers: developing effective initiatives to support and guide a sustainable territorial capital growth. Implications for managers and investors: improving managerial and investors’ decisions by disclosing a complete picture of the enterprise, also outside the firm boundaries. Originality/value – The study contributes to intangibles/intellectual capital literature by shedding light on the importance of including territorial capital in a company’s report to improve the definition of the firm’s value. Accounting of the territorial capital would increase the awareness of the socio-economic environment value in which companies are located and its use.


The study explores the adversities faced by wompreneurs (Women Entrepreneurs) of Odisha and talks about their work-life balance issues. The paper presents the viewpoint (motivation) of wompreneurs as to why they think of starting an enterprise of their own. Focus is also laid onthe supportive factors of wompreneurs and factors that disrupt maintaining their work-life balance.The present exploratory paper is the outcome of a pilot study that has been performed using thematic investigation & analysis to find out solutions for the above-mentioned issues. For this paper, Qualitative research is used, which is conducted by assimilating data from personal interviews and thematically analyzing it. Suggestions for better work-life balance are given at the end. The area of work-life balance is devoid of studies in India, where wompreneurs are expected to have a better work-life balance as they are their own “boss”, the paper tries to explore the authenticity of such assumptions. The model has been devised with the above research objectives to provide insight into motivating factors and work-life balance issues of wompreneurs, which can help the Government, policy-makers, research fraternity and other training counselling institutions to emphasize such emerging issues that would lead to empowered women as well as an empowered Nation. Keywords: Entrepreneurship, Wompreneurs, Case study, Work-life balance, Role conflict
