    Abstract Abstract Hainan Island fishermen have been engaged in fishing in Nanhai Zhudao (the Nanhai Islands) since ancient times. From sailing to the emergence of motorboats, the South China Sea fishermen have experienced different seafaring eras. Fishermen who work and live on the islands and reefs also have experienced living on islands seasonally to long-term. This article uses the inhabiting fishermen groups of the Xuande and Yongle Islands in Xisha Qundao (the Xisha Islands) as examples to demonstrate the unique livelihoods of the fishermen and reveal their role in the use of marine ecology to achieve sustainable development.

    Abstract Green credit is an important financial tool to coordinate the relationship between economic development and environmental protection. The Green Credit Guidelines (GCGs) issued in 2012 comprise the first formal, dedicated green credit policy. To test the effectiveness of the GCGs in green governance, in this study, we use the differences-in-differences (DID) method to test the impact of the implementation of the GCGs on enterprise green mergers and acquisitions (M&As) and further examine the performance of green M&As. The results show that the implementation of the GCGs have significantly promoted the green M&A activities of heavily polluting enterprises, and the promotion effect is more significant in enterprises with poor green innovation ability and enterprises with low financial marketization levels. Further research reveals that green M&As can improve the green innovation performance of enterprises. From the perspective of green M&As, in this paper, we expand the research on the effect of green credit policy, providing a decision-making reference for the promotion and improvement of subsequent green credit policy.

    Abstract Bi <semantics> 2 </semantics> Te <semantics> 3 </semantics> has been extensively used because of its excellent thermoelectric properties at room temperature. Here, 230–420 nm of Bi <semantics> 2 </semantics> Te <semantics> 3 </semantics> hexagonal nanosheets has been successfully synthesized via a “green” method by using ethylene glycol solution and applying polyvinyl pyrrolidone (PVP) as a surfactant. In addition, factors influencing morphological evolution are discussed in detail in this study. Among these parameters, the reaction temperature, molar mass of NaOH, different surfactants, and reaction duration are considered as the most essential. The results show that the existence of PVP is vital to the formation of a plate-like morphology. The reaction temperature and alkaline surroundings played essential roles in the formation of Bi <semantics> 2 </semantics> Te <semantics> 3 </semantics> single crystals. By spark plasma sintering, the Bi <semantics> 2 </semantics> Te <semantics> 3 </semantics> hexagonal nanosheets were hot pressed into solid-state samples. We also studied the transport properties of solid-state samples. The electrical conductivity <semantics> σ </semantics> was 18.5 × 10 <semantics> 3 </semantics> Sm <semantics> − 1 </semantics> to 28.69 × 10 <semantics> 3 </semantics> Sm <semantics> − 1 </semantics> , and the Seebeck coefficient S was −90.4 to −113.3 µVK <semantics> − 1 </semantics> over a temperature range of 300–550 K. In conclusion, the observation above could serve as a catalyst for future exploration into photocatalysis, solar cells, nonlinear optics, thermoelectric generators, and ultraviolet selective photodetectors of Bi <semantics> 2 </semantics> Te <semantics> 3 </semantics> nanosheet-based photodetectors.

    Abstract Introduction In an ageing society, older adults are the main users of healthcare services, and Chinese healthcare systems have been struggling to meet the care demand of older adults. Due to the illness, many older inpatients cannot finish daily activities independently and require healthcare from caregivers. Evaluating the care needs of older adults and exploring the factors affecting safe care at multiple levels are conducive to providing systematic care services for older inpatients. This study aims to examine which and how factors impact safe care for older inpatients and propose a safe care theory to provide directions on improving the safe care system in the hospital.Methods and analysis A mixed-methods study with three interrelated research streams will be designed. (1) A safe care concept model: we will conduct a scoping review to extract the facilitators and barriers influencing the safe care of older inpatients and construct a concept model based on the socio-ecological model and the Yorkshire Contributory Factors Framework. (2) A safe care theory model: we will conduct a qualitative study with thematic analysis (aimed at older inpatients, caregivers and nurses) to define the concept connotations and propose a theory model. (3) A safe care theory: we will use the scales related to the theory model to test the concepts and statements. We will revise the theory model and derive a safe care theory based on the mixed-methods study results. This study will start in October 2023 and end in October 2025.Ethics and dissemination This study was approved by the ethics committee (No. 20221598). All participants will be provided with consent forms prior to data collection. The study will be disseminated via peer-reviewed manuscripts and conferences.Trial registration number ChiCTR2300067421.

    Abstract The dynamic prediction of large spacecraft is a time-consuming process. The impulse-based substructuring (IBS) method is an efficient and accurate method for the dynamic analysis of large-scale structures. The ordinary IBS method couples the substructure impulse response functions (IRFs) with coincident interface nodes. However, the interface nodes in a practical structure are usually mismatched. This paper extends the ordinary IBS method and presents a method for coupling multi-domain substructures, including IBS, FEM and modal substructures, with non-matching interfaces. Both displacement compatibility and force equilibrium are satisfied on the non-matching interfaces of substructures by introducing the normalized interpolation technique into the framework of IBS. To evaluate the performance of the proposed method, numerical models and a practical application with a lunar lander and a rover are presented. The main bodies of the lander and the rover are coupled by non-matching interfaces, and the coupled system is excited by a buffer load. With the employment of this proposed method, the computing time of the landing simulation of the lunar lander is dramatically reduced, and the results show strong agreement with references. It is demonstrated that the proposed method is accurate and efficient in the transient dynamic analysis of engineering structures.

    Abstract Hepatocellular carcinoma (HCC) is one of the cancers that has the highest morbidity and mortality rates. In clinical practice, there are still many limitations in surveilling, diagnosing, and treating HCC, such as the poor detection of early HCC, the frequent post-surgery recurrence, the low local tumor control rate, the therapy resistance and side effects. Therefore, improved, or innovative modalities are urgently required for early diagnosis as well as refined and effective management. In recent years, nanotechnology research in the field of HCC has received great attention, with various aspects of diagnosis and treatment including biomarkers, ultrasound, diagnostic imaging, intraoperative imaging, ablation, transarterial chemoembolization, radiotherapy, and systemic therapy. Different from previous reviews that discussed from the perspective of nanoparticles’ structure, design and function, this review systematically summarizes the methods and limitations of diagnosing and treating HCC in clinical guidelines and practices, as well as nanomedicine applications. Nanomedicine can overcome the limitations to improve diagnosis accuracy and therapeutic effect via enhancement of targeting, biocompatibility, bioavailability, controlled releasing, and combination of different clinical treatment modalities. Through an in-depth understanding of the logic of nanotechnology to conquer clinical limitations, the main research directions of nanotechnology in HCC are sorted out in this review. It is anticipated that nanomedicine will play a significant role in the future clinical practices of HCC.
