The flame behavior of engine fires, such as those caused by leaked fuel coming into contact with an ignition source, is significant in practical applications, where flame detection is used to minimize the damage of the attendant ship fire safety problem. In this work, the flame behavior of hot-surface ignition (HSI) under crossflow was studied, with a particular focus on the difference in lateral airflow velocities for HSI-driven flame deviations at the windward and leeward sides of a ship engine room; a problem such as this has not previously been quantified. Full-scale experiments were conducted in a ship engine room using marine diesel and hydraulic oil as the fuel, and by adopting lateral airflow with the velocities of 0 m/s, 1.0 m/s, 3.0 m/s, and 5.0 m/s, together with an HSI mechanism consisting of marine diesel and hydraulic oil coming into contact with elevated hot-surface temperatures. The results show that the effects of disturbing the combustible gaseous mixture for marine fuel HSI, at both the windward and leeward sides, strengthened as the airflow velocity increased. The HSI position of the leaked marine fuel in the engine room was strongly dependent on ventilation, while that under the airflow condition decreased with the increase in the hot-surface temperature. A model was proposed to characterize this difference on the basis of the HSI height, which was defined as the ratio of the height during the initial HSI to the stationary period. The results indicate that the scale of the flame gradually increased in the horizontal direction, which was significantly different from the result in the scenario without mechanical ventilation. The results also revealed that the fluctuation of hydraulic oil through the temperature field was significant and lasted for a long time under a low HSI temperature.

To extend initial ignition-related fire prevention in ship engine room, this work presents a case study of marine diesel leakage for identifying accidental ignition by hot surface. Based on a self-designed experimental platform, a full-scale innovative experimental arrangement was conducted for diesel leakage-related hot surface ignition (HSI) tests in a ship engine room. A series of parameters (e.g., heat transfer, evaporation mode, ignition position, ignition delay time, flame instability, and combustion behavior) for improving the initial HSI of diesel leakage on an edge-limited hot surface were analyzed. A transient sequence corresponding to a change in leakage flow rates ranging from 7.5 mL to 25 mL was tested, and hot surface temperatures (HSTs) were adjusted between 390 °C to 525 °C. Puffing motion accelerated the mixing of HSI-driven vapors with fresh air, which was affected by the edge-based limitation and HSTs. The case study identified the effects of hot surface shape and the most important combinations of HSI-driven combustion characteristics for estimating initial ignition responses. Based on this current work, prediction models were proposed for determining the HSI height of marine diesel for varying leakage flow rates and HSTs. The results indicate that HSI height increases with leakage flow rate and HSI position is influenced by edged hot surfaces, leading the vertical centerline to shift towards the side of the edge structure. The results also revealed that the ignition delay time of diesel leaked onto an edged hot surface decreases as leakage flow rate increases. This change causes the initial HSI to occur earlier, potentially creating an extra risk in ship engine rooms.

As humanity’s moral failure leads to wild aquatic resources decline, habitat destruction and community tension, an ethically sound path towards good governance is increasingly needed globally. To epitomize sustainable paradigm shifts of grassroots practicalities in the fish sector, an ethical governance framework is initially conceptualized with a meta-governance infrastructure and a value-based decision-making mechanism. The ethical approach is then contextualized by using fish-specific evidence and outlining evolution of participatory fisheries and aquaculture management in rural China as a case study. The empirical investigation of socio-ecological justice manifested in social empowerment, ethical conduct and ecological resilience reveals that in China: fisheries and aquaculture governance models have been transforming from hierarchical governance to integrated governance combining hierarchy, market and community; participatory ethics are embedded in civil organizations upgraded from fishery association, offices, leagues to societies and cooperatives, indicating a multi-stakeholder governance mechanism steered by the government as meta-governor; villagers’ committees play a critical intermediary role in extending township governance and promoting autonomy of fishermen (farmers); local knowledge and traditional code of conduct regulates fish activities of fishermen (farmers) ready for community cooperation and mutual assistance; fish communities adopt socio-ecological measures to ensure property rights to fish (farm) and conserve aquatic resources. The current study aims to provide value reference in leveraging justified policy tools while promoting legitimacy of fish grassroots governance, in hope of contributing to a greener future of fisheries and aquaculture worldwide.

As a geographical dimension of justice, spatial justice is characterized by the interplay of social justice and heterogeneous spaces, including the ocean. Despite the generous contribution of ocean to humankind, concerns over aquatic spatial justice are disproportionately lacking. Among the core disruptors of ocean justice, illegal, unreported and unregulated (IUU) fishing imposes a major threat to global fisheries governance. The synthesis of spatial analysis and justice perspective can generate new insights to help understand and potentially address IUU fishing. To examine the spatial (in)justices concerning IUU fishing, we first propose a novel tripartite framework that envisions space as a form of opportunity, society and rights to externalize its socio-environmental implications. Then we integrate productive, distributive and consumptive justices to examine the spatial variations of IUU stakeholders along the fish value chain, and use stakeholder analysis to investigate spatial powers and conflicts regarding both a micro scale of fish communities, and a macro scale of states (coastal state, flag state, port state and market state) and supernational players (regional fisheries management organizations and marine protected areas). It is discovered that certain regions provide greater spatial benefits that stimulate IUU behaviors; IUU misconducts cause spatial differentiation and spatial deprivation that disrupt social orders in fish communities; space can empower stakeholders’ inclusive and proper engagement into the place-based management process against IUU fishing. Since the spatialized vision has been increasingly highlighted in marine fisheries management, it is suggested to intervene in the world ocean by leveraging spatial knowledge, managing spatial conflicts and facilitating spatial action, in order to promote spatial justice and better combat IUU fishing globally.

By leveraging their own featured specialties to facilitate the training of Master of Translation and Interpreting (MTI) program, industrial-oriented colleges and universities can seize the golden opportunity brought by the "new liberal arts" initiative to cultivate interdisciplinary language service talents tailored to the market needs. Through a status quo analysis, this study attempts to examine multiple aspects concerning the training models of MTI program in industry colleges and universities, including educational objectives, curriculum setting, faculty allocation, and practical training, in an effort to discover a unique path of training compound MTI professionals. Given the shared challenges faced by such institutions, it is suggested to further create a favorable interdisciplinary learning environment, improve the whole process of talent training, and boost the employability of students in future.
