Data were obtained from the IMO GISIS database (2012–2023), comprising 3859 ships. Due to significant data gaps in key parameters (e.g., Vref, PME, Draught), Random Forest Regression (RFR) was employed to impute missing values and enable complete EEDI calculation based on the IMO formula under a Heavy Fuel Oil assumption. Model performance was validated using R<sup>2</sup> and Mean Absolute Error (MAE) metrics, and time series stationarity was assessed using the Augmented Dickey-Fuller (ADF) test. Following data refinement, a multiple linear regression model was used to predict 2030 EEDI values, using ship-specific features such as DWT, year of delivery, Vref, and PME. Results indicate that container ships are on track to meet or exceed Phase 3 requirements, while bulk carriers and tankers may fall short without further technological or operational improvements. The study demonstrates the utility of machine learning in addressing maritime data limitations and provides a data-driven forecast framework for evaluating regulatory compliance and informing policy decisions in coastal and oceanic transport planning.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107910"},"PeriodicalIF":5.4,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three studies were conducted, each testing the effects of monolingual, bilingual, and trilingual packaging formats. A total of 445 participates were recruited, with a final valid sample is 397 respondents. The empirical analysis employed structural equation modeling (SEM) to examine the influence of different packaging language strategies on tourists' perceptions of both functional value and emotional value, and their subsequent purchase intention. In addition, comparative analyses were performed to assess the relative impact of the monolingual, bilingual, and trilingual packaging conditions. The findings reveal that monolingual and bilingual packaging significantly enhance tourists' perception of functional value, while trilingual packaging more effectively stimulates emotional value, thereby leading to stronger purchase intentions. Furthermore, the study identifies cultural identity as a key moderating variable in multilingual packaging contexts, influencing the strength and direction of tourists’ responses to linguistic cues. These results provide valuable insights into how tourists interpret and respond to multilingual packaging, offering practical guidance for the tourism sector in developing targeted promotional strategies. By aligning product communication with cultural values and tourist identity, stakeholders can not only increase purchase likelihood but also contribute to sustainable development goals in the ocean and coastal tourism sector.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107902"},"PeriodicalIF":5.4,"publicationDate":"2025-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144919693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using Hong Kong as a case study, this paper explores social preferences for various eco-shoreline design alternatives focusing on three key aspects: morphological changes, biodiversity enhancement, and the provision of recreational facilities, via the application of a discrete choice experiment. An online survey was conducted during October to November 2021, from which a total of 308 valid responses were received. The analytical results, based on the mixed logit models and the Equality Constrained Latent Class model, reveal that mangrove eco-shoreline is the most preferred, followed by rocky eco-shoreline and vertical eco-shoreline, while biodiversity enhancement and provision of recreational facilities are less preferred. About 54.9 % of the respondents pay little attention to the amount of donation associated with eco-shoreline implementation, corroborating a relatively strong social preference for transforming existing seawalls into eco-shorelines, irrespective of the amount of donation they might have to make. This study not only sheds additional light into the societal preference and valuation for eco-shoreline implementation, but also generates scientific evidence to inform plans and policies for concurrent coastal protection and biodiversity conservation.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107906"},"PeriodicalIF":5.4,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144913368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms through which multiple SDGs interact to influence SDG 14 across different spatial scales remain unclear. This study first identifies the five key SDGs (SDGs 6, 8, 9, 11, 12) most closely related to SDG 14, then it employs partial least squares structural equation modelling (PLS-SEM) to analyze the local impact of SDG synergies on SDG 14 in Chinese coastal areas. A spatial econometric model with a land-sea weight matrix further quantifies the cross-border effects of inland SDGs synergies on the performance of coastal SDG 14. We found that in terms of local interaction in coastal areas, economic growth (SDG 8) and sustainable consumption and production (SDG 12) positively impact SDG 14 in coastal areas, with direct effects of 0.55 and 0.422, respectively. In contrast, industrialization and infrastructure (SDG 9) and sustainable cities and communities (SDG 11) exert suppressive effects, with direct impacts of −0.567 and −0.554. It is worth noting that all indirect effects are insignificant, suggesting that SDG synergies in coastal areas have no impact on SDG 14. This is due to the complexity of the interaction pathways, which causes the effects to cancel each other out. At the level of cross-border interaction between land and coastal area, inland SDG synergies generate positive spillover effects on coastal SDG 14, with stronger effects from non-adjacent inland provinces than from adjacent ones. These findings underscore the need for policy interventions to strengthen coordination among the Sustainable Development Goals (SDGs) to avoid offsetting effects; Cross-regional coordination is essential, especially to encourage non-adjacent inland contributions.

It is observed that regular nourishments serve to halt structural coastline retreat. The coastline built out, on average, which was necessary to achieve maintenance of the most erosive areas. Additionally, strong dune growth is observed since the start of coastline maintenance, thanks to wind-driven transport of nourished sand and more dynamic dune management. Nourishments thus contribute positively to flood safety, although flood safety is not an automatic benefit of coastline maintenance. Space for recreation and nature is maintained or improved: the dry beach width was unaffected, and dune areas have grown. Further, it is reported that the impact of nourishments on the coastal ecosystem is local and temporary, leading to the inference that uses and values of the coast are being maintained sustainably through regular nourishments.

Through desk research and 18 stakeholder interviews, we identify key barriers and enablers within six governance functions: knowledge development, direction of search, legitimacy creation, resource mobilisation, market formation and entrepreneurial experimentation. Our findings reveal that while market formation shows promise across regions, significant challenges persist in legitimacy creation and knowledge development. Regulatory complexity and fragmented responsibilities emerge as primary barriers to innovation, particularly affecting small and medium-sized enterprises. Resource constraints manifest differently across regions, from infrastructure limitations in Sicily to workforce shortages in Denmark and Estonia. Based on these insights, we propose three key policy interventions: regulatory process simplification through sandboxes and administrative one-stop shops, innovative financing mechanisms including blue bonds and accelerator programs, and enhanced collaborative frameworks through regional networks and public-private partnerships. This study contributes to innovation systems theory and practice by demonstrating how systematic analysis of governance functions can inform targeted interventions to support sustainable blue bioeconomy development.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107899"},"PeriodicalIF":5.4,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144893467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
