Time to seize the digital evolution: Adoption of blockchain in operations and supply chain management among Malaysian SMEs

This study aims to investigate the effects of relative advantage, complexity, upper management support, cost, market dynamics, competitive pressure and regulatory support on blockchain adoption for operations and supply chain management among Small-Medium Enterprises (SMEs) in Malaysia. Unlike existing studies that employed linear models with Technology Acceptance Model or United Theory of Acceptance and Use of Technology that ignores the organisational and environmental factors, we adopted the Technology, Organisation and Environment Framework that covers the technological dimensions of relative advantage and complexity, organisational dimensions of upper management support and cost and environmental dimensions of market dynamics, competitive pressure and regulatory support. Empirical data from 194 SMEs were investigated and ranked using a nonlinear non-compensatory PLS-ANN approach. Competitive pressure, complexity, cost and relative have significant effects on behavioural intention. Market dynamics, regulatory support and upper management support were insignificant predictors. SMEs often lack resources for technological investments but faces same requirements for streamlining business processes to optimise returns and blockchain presents a viable option for SMEs’ sustainability due to its features of immutability, transparency and security that have the potential to revolutionise businesses. This study contributes new knowledge to the literature on factors that affect blockchain adoption and justifications were discussed accordingly.

Detection ofNeisseria Gonorrhoeae by polymerase chain reaction (PCR)

Three different sets of primers were designed using FASTA homology search and PRIMERSELECT for the specific detection ofNeisseria gonorrhoeae using polymerase chain reaction (PCR). These primers amplified the highly conserved regions of genes for Open Reading Frame (ORF), Outer Membrane Protein (OMP) and 23S rRNA sequences ofN. gonorrhoeae. Each of the PCR primer set was evaluated using the DNA samples isolated from eight different positive isolates ofN. gonorrhoeae cultured from urethral swabs of patients visiting Maulana Azad Medical College and Safdarjung Hospital. Amplification products were analyzed on agarose gel electrophoresis. Two sets of PCR primers, designated as Ngu1/Ngu2 and Ngu5/Ngu6, specific for ORF and OMP gene respectively, amplified four regions of the gene which may help to differentiate the various strains ofN. gonorrhoeae infecting indigenous population. In contrast, a single, specific PCR product of 650 bp was visualized on agarose gel with primers Ngu3/Ngu4, amplifying the 23S rRNA gene. Under optimum conditions, as low as 25ng of DNA isolated from eight different clinical strains ofN. gonorrhoeae could be detected by PCR using Ngu3/Ngu4 set of primers. Our results suggested that Ngu3/Ngu4 could serve as good primers for the specific, reproducible and sensitive diagnosis ofNeisseria gonorrhoeae from clinical samples.
