There are essentially no reports on the use of modern biotechnological methods on the study of cestode parasites in the Philippines, Indonesia or Malaysia. The only recent reports of cestode studies in these countries have been on reports of new species in animals and on prevalence rates of cestode parasites in humans; Taenia solium and cysticercosis, Taenia saginata and Hymenolepis nana, etc. Reports on the use of biotechnology has emanated from outside the area on cestodes of humans and animals, and some of these methods could be used to study cestodes in this part of the world.
Plaque reduction neutralization tests, using five group A arboviruses (chikungunya, Ross River, Getah, Bebaru and Sindbis), were done on sera from human populations in 44 Southeast Asia and Pacific island localities. Specificity of the plaque neutralization test was determined by examining convalescent sera from patients with known alphavirus infections. Chikungunya-specific neutralizing antibodies were demonstrated in sera of persons living in South Vietnam, Northern Malaysia, Indonesia (Kalimantan and Sulawesi), as well as Luzon, Marinduque, Cebu and Mindanao islands in the Philippines. Evidence of Ross River virus infection was found among populations living in West New Guinea and Papua New Guinea mainland, the Bismark Archipelago, Rossel Island and the Solomon Islands. There appeared to be no geographic overlap in the distribution of chikungunya and Ross River viruses, with the separation in their distribution corresponding with Weber's line in the Pacific. Sindbis neutralizing antibodies were found in 7 of 21 populations sampled, but in general the prevalence of infection was low. Four sera, from Vietnam, Malaysia and Mindanao gave monospecific reactions with Getah virus. No evidence of specific Bebaru virus infection was detected. The epidemiology of these five alphaviruses in Southeast Asia and the Pacific islands is discussed.
In recent years, the concept of a circular economy (CE) has gained importance and attracted significant attention among scholars and practitioners. Research that examines the firm's supply chain capabilities and orientation for performance is well established nonetheless still lacking in supporting the transition from a linear economy to a circular economy. The firms can foster a closed-loop supply chain orientation (CLSCO) through strategic green capabilities as an alternative obtainable to SC firms to achieve CE performance. Thus, this study is interested to examine the antecedents and outcomes of CLSCO by applying the Resource-Based View and Natural Resource-Based View theories. In total, 150 Malaysian manufacturers responded to the survey and were analysed using the SEM Lisrel method. Among the hypotheses tested, only one had no direct effect on CLSCO, and that was the recovery capacities. The remaining hypothesis indicates that CLSCO is positively affected by integration and production capabilities. In contrast, the results of CLSCO indicate that the extent of a company's CLSCO does affect its success in the circular economy. The study concludes, based on the RBV and NRBV principles, that the success of firms in optimising their resources would enable them to use the CLSCO and attain CE performance. Thus, there are numerous ways in which this study can provide practitioners with valuable research insights.
