Knowing the challenges of keeping and manipulating more and more immutable transaction records in a blockchain network of various supply chain parties and the opportunities of leveraging sophisticated analyses on the big data generated from these records, design of a robust blockchain architecture based on a cloud infrastructure is proposed. This paper presents this technical design with consideration of the technical sustainability in terms of scalability and big data processing and analytics. A case study was used to illustrate how the technical sustainability is achieved by applying the proposed technical design to the real-time detection of the maritime risk management. This case also illustrates how machine learning mechanism helps to reduce maritime risk by guiding a cargo ship to adjust to the planned or safe route from a detour to a danger zone. This paper also discusses the implications for further research direction.

This paper examines the correlation between curriculum reforms and the development of generic competencies among Hong Kong tertiary students (or secondary leavers who were admitted to Associate Degree and Higher Diploma). A total number of 3626 freshmen completed a set of self-assessment questionnaires, which were used to analyse the correlation between five generic competencies, across three academic years from 2010 to 2012. Five of the generic competencies, which were highlighted in the proposed new three-year New Senior Secondary (NSS) academic structure, were measured and compared between students from different academic backgrounds. The finding of the study indicated significantly higher scores in generic competencies for the traditional Hong Kong Advanced Level Examination (HKALE) secondary school curriculum in 2012 compared to earlier cohorts, whilst in general no significant difference was found between students from the traditional curriculum and the new academic structure of the Hong Kong Diploma of Secondary Education (HKDSE) in the mixed 'double cohort' year of 2012. The result points to the potential early impact of NSS on students' generic skill development across both the old and new curriculum.

PurposeA new academic structure for senior secondary and higher education was introduced to Hong Kong in 2009/2010. This paper aims to: (1) compare the cohort from the old academic structure (Cohort 2010) and the cohort from the new academic structure (Cohort 2015) on the 14 categories of generic competencies; and (2) compare these attributes among students from different divisions in a tertiary institution in Hong Kong.Design/methodology/approachSelf-Assessment of All-Round Development (SAARD) questionnaires were distributed to students who took the two-year sub-degree programmes offered by the College of Professional and Continuing Education, The Hong Kong Polytechnic University in 2010 and 2015 on a self-administered basis. A total of 4,424 students have returned the questionnaires. Data were analyzed with t-test to compare between the two cohorts.FindingsWhen comparing Cohort 2015 with Cohort 2010, significantly higher scores were observed on five areas such as global outlook and healthy lifestyle (p<0.05). Significantly lower scores were observed on the other five areas such as problem solving, critical thinking and leadership (p<0.05). Students from all divisions unanimously showed higher perceived rating on social and national responsibility but lower perceived rating on leadership (p<0.05).Originality/ValueThe elimination of one public examination, the newly included components such as Other Learning Experiences (OLE) and the compulsory Liberal Studies were believed to contribute partially to the diverse responses of the two cohorts. The dramatic change of the curriculum has not changed the examination culture in Hong Kong which may hinder the development of generic skills among students.
