Tuna resources in the Western and Central Pacific Ocean are the world's largest and most valuable fisheries of their type and are vital to the economy and the sustainable development of the region. However, the region witnesses a rapid decline in tuna resources and the depletion of species such as bigeye and yellowfin tunas, and overharvesting of the other species. This study investigated the collaborative management model used to manage migratory tuna resources. The study followed a case study design with a focus on the Western and Central Pacific Ocean Fisheries Commission. Forty interviews were conducted with key stakeholders. The findings indicated that six factors, namely, structure and size, self-interest, self-enforcement, leadership style, equality of power, and culture, affected significantly the outcomes of a collaborative management model. The findings also provide important insights on how the factors influenced the outcomes. The study contributes to a better understanding of international governance of common-pool resources (CPRs) and its challenges, and thus helps policymakers develop strategies for managing migratory fishing resources for the sake of economic viability and sustainability in the region.

PurposeThe well-being of the elderly is a growing issue of concern for countries around the world. One way to enhance the elderly well-being is to provide housing options suitable to their needs and lifestyle. Retirement village is an accommodation concept foreign to the Malaysian population. Therefore, the purpose of this paper is to bridge this literature gap by analyzing factors that may inhibit or motivate the buying intention of a retirement village unit among the elderly in Malaysia.Design/methodology/approachData were collected from 261 Malaysian elderly and analyzed using structural equation modeling PLS.FindingsThe results indicated that attitude, subjective norm, perceived behavioral control and social sustainability were significant predictors that explained elderly buying intention of retirement village.Originality/valueThe study also found a significant moderating role of religion in attitude–intention relationship. The paper concludes with the study's implications, limitations and recommendations for future research.

Using severe accident analysis program MELCOR, the small break loss of coolant accident (SBLOCA) analysis model was established for a marine reactor. The release and migration of radionuclides were analyzed during a severe accident induced by SBLOCA. The analysis of the hydrogen source term release showed that the maximum hydrogen release amount was 248.567 kg, and the hydrogen release amount accounted for less than 4% of the air volume. So, there would be no danger of hydrogen explosion accidents. The research mainly focused on the behaviors of the release, the transport, the retention, and the final distribution of inert gases represented by Xe, volatile gases represented by CsI, and nonvolatile nuclides represented by Ba. The results showed that the reactor core exposed completely with a lagging by 510 s and the initial release time of nuclides was lagged by 1916 s. The release shares of Xe in the primary circuit system, the containment, and the environment were 0.013%, 0.06%, and 32.71%, respectively. Also, Ba shared 0.016%, 0.0032%, and 3.28%, respectively, and CsI shared 0.0145%, 0.0012%, and 2.845%, respectively.
